Description:FIELD OF THE INVENTION

[0001] The present invention relates to a vehicle window occluding device that is developed to manage and control sunlight exposure, temperature, and air quality inside a vehicle by utilizing adaptive and dynamic shading means and air purification features, thereby improving the overall driving experience.

BACKGROUND OF THE INVENTION

[0002] In vehicles, the need to manage sunlight and ensure the comfort of occupants has long been addressed using various traditional solutions, such as manual window shades, blinds, or curtains. These methods, however, suffer from several drawbacks, including limited adjustability, cumbersome installation, and insufficient ability to regulate the intensity of sunlight. Additionally, manual adjustment of such arrangements is inconvenient and ineffective in optimizing comfort for all passengers. The lack of efficient air filtration and cooling options further contributes to discomfort, especially when vehicles are exposed to prolonged direct sunlight. Hence, more efficient, automated solutions were sought to improve occupant experience.

[0003] Traditionally, for blocking sunlight inside a vehicle people generally use manually operated window shades and curtains. These were typically made from fabric or vinyl and drawn up or down to block the sun. However, the user had to manually adjust these curtains, which is inconvenient, especially while driving. So, people also use sunshades and visors as these small, foldable equipment’s, usually placed on the windshield or side windows, and were used to reduce glare and heat during sunny days. Some vehicles also featured adjustable visors attached to the dashboard or rearview mirror. But these equipment’s often block visibility and do not provide full sun protection, making them less effective in managing sunlight and heat across the entire vehicle.

[0004] US6275998B1 discloses about an invention that includes a vision occluding eye shield which completely blocks the peripheral vision of the wearer to the discernment of motion and which blocks most or all of the superior field of vision of the wearer, and preferably also blocks an upper portion of the inferior field of vision of the wearer, to the discernment of motion. When worn by a vehicle passenger the device prevents car sickness by blocking perception of objects passing through the peripheral field of vision in the side windows and through the front window, while allowing the wearer to focus on tasks or objects within the vehicle by looking through the unoccluded portion, or to look out the vehicle windows by slightly tilting the head back.

[0005] CN219948092U discloses about an invention that includes a shielding device and a vehicle, wherein the shielding device comprises: the driving device is arranged on the window shade; the driving device is arranged in the ceiling; one end of the window shade is arranged on the driving device and is in transmission connection with the driving device, and the other end of the window shade penetrates through the through hole and can be hidden in the ceiling and selectively lifted in the space below the ceiling under the driving action of the driving device. Through setting up the window shade in the ceiling to use drive arrangement to drive the window shade, thereby can make the window shade rise and descend, shrink in the ceiling when the window shade is not used, can realize the hidden design of window shade, through the through-hole downwardly stretching when the window shade is used, can stop at any time, and can reach the effect of shielding when stretching to a certain extent, thereby form safe individual space.

[0006] Conventionally, many devices have been developed that are capable of occluding vehicle window. However, these devices are incapable of efficiently controlling both sunlight and air quality within a vehicle. Additionally, these existing devices also lack in reducing the reliance on the vehicle’s power supply.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that is capable of efficiently controlling both sunlight and air quality within a vehicle by using adaptive means that respond to real-time conditions, thereby ensuring comfort and enhancing the well-being of occupants. In addition, the developed device also harnesses available energy from natural sources to power itself, thereby reducing the reliance on the vehicle’s power supply.

[0009] An object of the present invention is to develop a device that is capable of dynamically managing the intensity of sunlight entering a vehicle, in view of ensuring that occupants are shielded from excessive exposure to sunlight while maintaining an optimal level of comfort within the vehicle.

[0010] Another object of the present invention is to develop a device that is capable of adjusting and regulating environmental conditions inside the vehicle, such as temperature and air quality, without requiring manual intervention from the user.

[0011] Yet another object of the present invention is to develop a device that is capable of adjusting the position and movement of occupants, for ensuring that shading and air purification means are optimally positioned to address specific needs.

[0020] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0021] The present invention relates to a vehicle window occluding device that enable the adjustment of sunlight penetration into the vehicle, in view of allowing for effective protection of occupants from harsh sunlight while maintaining an ideal atmosphere for comfort within the vehicle.

[0022] Referring to Figure 1, a perspective view of a vehicle window occluding device is illustrated, comprising a frame 101 having a plurality of suction cups 102 mounted at a rear portion of the frame 101, a pair of L-shaped telescopic arms 103, each having a motorised roller 104 at an upper end, each of the roller 104 is provided with a spool of a shielding sheet, a plurality of hooks 105 arranged at an edge of the frame 101, a sliding unit 106 provided with each lateral edge of the frame 101, a plurality of clamps 107 are disposed at each the sliding unit 106, the shielding sheets comprising a first shielding sheet 108 provided with one of the roller 104, the first shielding sheet 108 having a plurality of pouches 109 arranged in a grid, a container 110 disposed in the frame 101, the shielding sheets further comprising a second sheet 111 spooled in one of the roller 104, having a plurality of hollow sections having filter, each of the sections is provided with a pair of iris holes 112, an iris aperture 113 provided in the sheets, a plurality of rectangular plates 114 along periphery of the frame 101 by means of articulated L-shaped telescopic bars 115, an air blower 116 is attached with the frame 101, an artificial intelligence-based imaging unit 117, installed on the frame 101, a solar cell 118 is embedded on each of the plates 114, an L-shaped articulated telescopic pole 119 having a motorised brush 120 at an end.

[0023] The device disclosed herein comprising a frame 101 that is equipped with a plurality of suction cups 102 (preferably 2 to 6 in numbers) strategically positioned at the rear portion of the frame 101, enabling the secure mounting of the frame 101 over a vehicle window. These suction cups 102 are designed to adhere firmly to the smooth surface of the vehicle window, providing stability and support for the frame 101 during operation.

[0024] The suction cups 102 are regulated to create a vacuum seal, ensuring that the frame 101 remains securely attached to the window without causing damage to the surface. This allows for reliable and temporary mounting of the frame 101 on the vehicle window, facilitating ease of installation and removal.

[0025] The suction cups 102 work by creating a vacuum seal between the cup and the surface it is applied to. Upon pressing the suction cups 102 onto a surface, air is expelled from the cup, reducing the internal pressure. The external atmospheric pressure then pushes the suction cups 102 tightly against the surface, forming a secure attachment. A valve is used to hold the air in, maintaining the vacuum, and ensuring that the suction cups 102 stays in place. The seal is maintained as long as the pressure difference remains intact, providing a firm grip until released manually.

[0026] A pair of L-shaped telescopic arms 103 mounted on the frame 101, connected by means of ball and socket joints, allowing for rotational and angular adjustments. Each arm 103 is equipped with a motorized roller 104 at its upper end, with each roller 104 spooled with a shielding sheet. The roller 104 enable the controlled deployment or retraction of the shielding sheets, which is extended or retracted as needed to cover or uncover the intended surface.

[0027] The arms 103 are pneumatically actuated, wherein the pneumatic arrangement of the arms 103 comprises of a cylinder incorporated with an air piston and the air compressor, wherein the compressor controls discharging of compressed air into the cylinder via air valves which further leads to the extension / retraction of the piston. The piston is attached to the telescopic arms 103, wherein the extension / retraction of the piston corresponds to the extension / retraction of the arms 103. The actuated compressor allows extension of the arms 103 to position the motorised roller 104 at an appropriate position.

[0028] The motorized roller 104 mentioned above is a mechanical unit designed to rotate on its axis with the help of an integrated electric motor. The cylindrical roller tube serves as a surface for supporting, and unwinding the positioned shielding sheet. The motorized roller 104 is equipped with an electric motor that provides the rotational power necessary to turn the roller 104. The motor is connected to the roller tube through a drive mechanism, which involves gears, belts to transfer the motor’s rotational force to the roller 104, causing it to rotate for unrolling shielding sheet.

[0029] Synchronously, the motorized ball and socket joint mentioned here consists of a ball-shaped element that fits into a socket, which provides rotational freedom in various directions. The ball is connected to a motor, typically a servo motor which provides the controlled movement. The arms 103 is attached to the socket of the motorized ball and socket joint, the microcontroller sends precise instructions to the motor of the motorized ball and socket joint. The motor responds by adjusting the ball and socket joint and rotates the ball in the desired direction, and this motion is transferred to the socket that holds the arms 103. As the ball and socket joint move, it provides the necessary movement to the arms 103.

[0030] A user interface is designed for integration with a computing unit, which facilitates communication with a communication unit linked to a microcontroller positioned on the frame 101. This configuration enables the user to input commands via the interface to selectively control the deployment of the shielding sheets. The microcontroller processes these inputs and actuates the necessary components of the device, ensuring that the shielding sheets are deployed or retracted based on the user's preferences and requirements. This allows for efficient operation and customization of the device's functionality.

[0031] A plurality of hooks 105 (preferably 2 to 6 in numbers)are strategically positioned along the edge of the frame 101, designed to engage with iris aperture 113 incorporated within the shielding sheets. This engagement serves to stabilize the position of the deployed sheets, ensuring that they remain securely in place during use. The hooks 105, by interfacing with the iris aperture 113, effectively prevent any shifting or undesired movement of the sheets, maintaining their intended alignment and functionality.

[0032] On each lateral edge of the frame 101 a sliding unit 106 is provided that is directed by the microcontroller to translate multiple clamps 107 (preferably 2 to 6 in numbers) that are disposed at each the sliding unit 106. The sliding unit 106 consists of a pair of sliding rail fabricated with grooves in which the wheel of a slider is positioned that is further connected with a bi-directional motor via a shaft. The microcontroller actuates the bi-directional motor to rotate in clockwise and anti-clockwise direction that aids in rotation of shaft, wherein the shaft converts the electrical energy into rotational energy for allowing movement of the wheel to translate over the sliding rail by a firm grip on the grooves. The movement of the slider results in translation of the clamps 107.

[0033] The clamps 107 used herein has an open side and a curved side, forming a partial circle or a half-moon shape. At the open side of the clamps 107, there is a screw mechanism which includes a threaded screw or spindle and an electric motor. As the motor rotates it causes the screw to move in or out, which in turn adjusts the width of the clamps 107 opening and eventually applies the required force to grip the edges of the sheet to prevent a flapping of the sheet.

[0034] The shielding sheets disclosed above include a first shielding sheet 108, which is mounted on one of the roller 104. This first shielding sheet 108 is designed with a plurality of pouches 109 arranged in a grid pattern, with each pouch 109 containing liquid crystal. The liquid crystal serves to partially occlude sunlight, providing adjustable shading. The liquid crystal is supplied to these pouches 109 through conduits that are connected to a container 110 housed within the frame 101. The container 110 holds the liquid crystal and ensures its distribution into the pouches 109, allowing for the regulation of sunlight penetration for enhancing the effectiveness of the shielding sheets.

[0035] Simultaneously, a temperature sensor is installed within the container 110, which monitors temperature of the liquid crystal. The temperature sensor comprises crucial components such as an infrared sensor, an optical arrangement, and a detector. It functions on the principle of detecting infrared radiation emitted by the liquid crystal. When the temperature exceeds absolute zero, it emits infrared radiation. The sensor captures this radiation using its optical arrangement, directing it onto a detector. Common detectors, are like thermopiles or pyroelectric sensors, which then convert the received infrared energy into an electrical signal. This signal undergoes processing by microcontroller, translating it into a temperature reading of the liquid crystal stored within the container 110.

[0036] The microcontroller compares the monitored temperature with a pre-feed range of temperature stored in a database linked with the microcontroller. In case the monitored temperature exceeds / recedes the range the microcontroller subsequently actuates a Peltier unit is installed in the container 110. The Peltier unit consists of two semiconductor plates, known as Peltier plates, connected in series and sandwiched between two ceramic plates. When an electric current is applied to the Peltier unit, one side of the unit absorbs heat from its surroundings, while the other side releases heat, thereby maintaining a temperature of the liquid crystal within the predetermined temperature range.

[0037] An air blower 116 is affixed to the frame 101 of the device via a ball and socket joint. This configuration enables the air blower 116 to be adjusted freely, providing optimal air flow directed toward the pouches 109 of the first shielding sheet 108. The air is blown onto the liquid crystal-filled pouches 109 to facilitate the cooling of the liquid crystal, thus regulating its transparency and enhancing the functionality of the shielding sheet. The blower 116 operation ensures that the liquid crystal remains within the desired temperature range, maintaining the sheet’s ability to effectively occlude sunlight as required.

[0038] The air blower 116 is activated by the microcontroller upon detecting a need for cooling. Once engaged, the motorized fan within the air blower 116 begins to rotate, generating airflow. This airflow is directed through ducts or nozzles connected to the blower 116, which is positioned near the liquid crystal pouches 109. The airflow cools the liquid crystal by dissipating excess heat. As the air passes over the pouches 109, it helps maintain the liquid crystal's operational temperature, preventing overheating and ensuring its continued effectiveness in occluding sunlight.

[0039] The shielding sheets further comprise a second sheet 111, which is spooled onto one of the rollers 104. This second sheet 111 features a plurality of hollow sections, each equipped with filters designed to purify the air inside the vehicle. Each hollow section contains a pair of iris holes 112, strategically placed to allow air to pass through the filters. This ensure that purified air circulates within the vehicle, improving the air quality for the occupants.

[0040] The iris holes 112 within each hollow section of the second sheet 111 are designed to control the airflow across the filter. As air enters through these holes 112, the size and positioning of the iris holes 112 regulate the volume of air flowing through the filter. The filter captures dust, allergens, and other particulates, and the purified air is directed into the vehicle. The iris holes 112, by adjusting the airflow, help ensure optimal filtration and efficient air purification inside the vehicle.

[0041] The frame 101 is installed with an artificial intelligence-based imaging unit 117, that locate occupants in the vehicle. The imaging unit 117 disclosed herein comprises of an image capturing arrangement including a set of lenses that captures multiple images of the surroundings and the captured images are stored within memory of the imaging unit 117 in form of an optical data. The imaging unit 117 also comprises of the processor which processes the captured images.

[0042] This pre-processing involves tasks such as noise reduction, image stabilization, or color correction. The processed data is fed into AI protocols for analysis which utilizes machine learning techniques, such as deep learning neural networks, to extract meaningful information from the visual data which are processed by the microcontroller to locate occupants in the vehicle.

[0043] The imaging unit 117 is installed via a motorized swivel joint that provides 360-degree rotation to the imaging unit 117. The motorized swivel joint allows for the rotation and movement of imaging unit 117. The motorized swivel joint comprises a motor that drives a rotating joint, often using gears or bearings to enable smooth movement. The joint permits 360-degree rotation, accommodating changes in direction to the imaging unit 117. Internal seals and bearings ensure that the connection remains leak-proof and operates with minimal friction and provides 360-degree rotation capability to the imaging unit 117, in order to aid the imaging unit 117 to locate occupants in the vehicle efficiently.

[0044] Simultaneously, a sun sensor that is integrated into the frame 101, detects the angle of incoming sunlight. This sensor continuously monitors the sunlight's position relative to the vehicle's location. Upon detecting the angle, the sensor transmits data to the microcontroller, which processes this information to perform required operation. The sun sensor works by detecting the intensity and angle of incoming sunlight. The sun sensor uses photodiodes to sense the direction and amount of light. When sunlight strikes the sensor, it measures the angle at which the light arrives and converts this data into electrical signals. The sensor then sends these signals to the microcontroller, which analyzes them and directs plurality of rectangular plates 114 arranged along the periphery of the frame 101, which are mounted via articulated L-shaped telescopic bars 115.

[0045] Further these bars 115 work in the similar manner as of arms 103 mentioned above and allow for the rotation of the plates 114, thereby enabling partial or complete occlusion of incoming sunlight. The rotation of these plates 114 is controlled in such a manner as to adjust their position, allowing for the regulation of sunlight entering the vehicle, thus enhancing comfort and reducing glare for the occupants. This also ensures that the plates 114 are efficiently adjusted to the desired angle in response to the environmental conditions.

[0046] Each of the rectangular plates 114 on the frame 101 is embedded with a solar cell 118 designed to convert incident solar energy into electrical energy. The solar cell 118 is strategically positioned to receive sunlight, and its purpose is to harness solar energy, which is then converted into electrical power. This electricity is utilized to power various components of the device, for ensuring that the device remains self-sustaining. The conversion process involves the photovoltaic effect, which occurs within the solar cell 118, generating electricity from the absorbed sunlight, and feeding this energy into the device for use.

[0047] The solar cell 118 captures sunlight, and the energy from the photons excites electrons within the semiconductor material. These excited electrons flow through the material to generate a direct current. This current is then collected by electrical contacts, producing usable electrical energy. The current generated is directly proportional to the intensity of the sunlight hitting the solar cell 118. The electricity generated is in a battery for later use when there is no sunlight.

[0048] A dust sensor is integrated into each of the plates 114 to detect the presence of dust particles on the surface of the solar cell 118. Upon detection of dust, the sensor transmits a signal to the microcontroller, which triggers the activation of an L-shaped articulated telescopic pole 119 that works similar as of arms 103 mentioned above. The pole 119 is fitted with a motorized brush 120 at its end, which is actuated to move across the solar cell 118. The brush 120 effectively scrubs the surface, removing any dust or debris, thereby ensuring that the solar cell 118 remains clean and maintains its optimal energy conversion efficiency.

[0049] The dust sensor continuously monitors the surface of the solar cell 118 for the accumulation of dust particles. When dust particles accumulate beyond a threshold level, the sensor detects the obstruction by analyzing changes in light reflection or optical clarity. Upon identifying the presence of dust, the sensor sends an electrical signal to the microcontroller, and triggering the cleaning process, for ensuring the solar cell 118 remains free of any type of dust build-up.

[0050] The motorized brush 120 is coupled with a DC motor that works on the principle of electromagnetic induction: the stator and the rotor. The stator generates a magnetic field which usually consists of a permanent magnet or as set of coils through which direct current flows. The rotor is the moving part of the motor. The armature is connected to a commutator which is a rotary switch that reverses the direction of the current in the coil every half-turn. As the armature rotates, the brush 120 ensure a continuous flow of current by reversing its direction at the right moments. When the DC is applied to the armature, a magnetic field is created around the coil due to the current flowing through the coil. As the DC electric motor rotates, the rotational force rotates the brush 120 to scrub the cell for cleaning of the dust.

[0051] Moreover, the battery is associated with the device for powering up electrical and electronically operated components associated with the device and supplying a voltage to the components. The battery used herein is preferably a Lithium-ion battery which is a rechargeable unit that demands power supply after getting drained. The battery stores the electric current derived from an external source in the form of chemical energy, which when required by the electronic component of the device, derives the required power from the battery for proper functioning of the device.

[0052] In an embodiment the present invention works in the best manner, where the frame 101 having the plurality of suction cups 102 are mounted at the rear portion of the frame 101 for mounting of the frame 101 over the vehicle window. The pair of L-shaped telescopic arms 103 are mounted on the frame 101 by means of ball and socket joints, each having the motorised roller 104 at the upper end. Each of the roller 104 is provided with the spool of the shielding sheet. The user interface is adapted to be installed with the computing unit to enable the computing unit to connect with the communication unit linked with the microcontroller provided on the frame 101, for deployment of the sheets. Plurality of hooks 105 are arranged at the edge of the frame 101 for engaging with iris holes 112 provided in the sheets, to stabilise the position of deployed sheets. The sliding unit 106 is provided with each lateral edge of the frame 101 having plurality of clamps 107 for gripping onto edges of the sheet to prevent the flapping of the sheet. The shielding sheets comprising the first shielding sheet 108 provided with one of the roller 104. The first shielding sheet 108 is having the plurality of pouches 109 each filled with the liquid crystal for partially occluding sunlight. The liquid crystal is filled into the pouches 109 by means of conduits connected with the container 110 containing liquid crystal. Thereafter the Peltier unit maintains the temperature of the liquid crystal within the predetermined temperature range.

[0053] In continuation, the Peltier unit also regulates in accordance with the temperature of the liquid crystal in the container 110 detected by the temperature sensor in the container 110. The air blower 116 blows air onto the pouches 109 for cooling of the liquid crystal. The shielding sheets further comprising the second sheet 111 spooled in one of the roller 104, having the plurality of hollow sections having filter. Each of the sections is provided with the pair of iris holes 112 for passage of air across the filters, for providing purified air in the vehicle. Plurality of rectangular plates 114 are arranged along periphery of the frame 101 by means of articulated L-shaped telescopic bars 115, for partially or completely occluding incoming sunlight by rotation of the plates 114. Further the artificial intelligence-based imaging unit 117, locates occupants in the vehicle to position the plates 114 to block sunlight from reaching the occupants. The solar cells 118 converts incident solar energy into electrical energy. Furthermore, the dust sensor detects dust on the solar cells 118 and simultaneously the microcontroller directs the L-shaped articulated telescopic pole 119 having the motorised brush 120 at the end for scrubbing the cells for cleaning of the dust.
