Description:A LID ACTUATING ASSEMBLY AND A METHOD THEREOF
FIELD OF THE INVENTION
[0001]
The present subject matter is related, in general to a lid assembly of a vehicle, and more particularly, but not exclusively to an actuation of the lid actuating assembly of the vehicle.
BACKGROUND OF THE INVENTION 5
[0002]
In recent times, there has been a growing dependence on electrical energy to power a wide range of electronic devices and increase in demand of electric vehicle (EV) industry. For charging of the EVs and HEVs, an ingress port or a charging port in a vehicle is provided to enable the charging of the vehicle's electric or hybrid powertrain. The ingress ports serves as the interface through which 10 electrical energy is supplied to a battery assembly of the vehicle's, allowing the battery assembly to store energy for later use in powering the electric motor or supporting the vehicle's hybrid operation. The presence of the ingress port is a fundamental feature in electric and plug-in hybrid vehicles. On the other hand, for traditional internal combustion engine vehicles, a fuel input port is common feature. 15 Further, all such vehicles also include a lid member which plays a crucial role in the overall functionality of an ingress port, serving as a protective barrier and ensuring the safety and efficiency of the charging process. The lid serves as a cover for the charging port, safeguarding it from external elements such as dust, debris, water, and other environmental factors that could potentially compromise the 20 integrity of the charging system.
[0003]
Typically, a lid is attached to an ingress port through a hinge mechanism that allows the lid to pivot when the lid is in open condition. A critical element in this mounting process is the spring mechanism. The spring is integrated into the hinge mechanism or directly connected to the lid to assist in the controlled 25 movement of the lid member. It applies force to facilitate the opening and closing operation, ensuring that the lid remains securely closed when not in use.

[0004]
Usually, to access the ingress port the lid is opened by push mechanism which can directly open the lid. In the push mechanism, the lid is equipped with a push-release mechanism that is typically integrated near the edge of the lid or in a predefined designated area. When a user applies a moderate amount of pressure to the predefined designated area, the push mechanism is activated. Upon activation, 5 the push mechanism releases a latch of the lid or disengages the locking mechanism, allowing the lid to pivot open. Furthermore, as per yet another known art, the lid is opened by means of an external switch which is easily accessible to any person. For example, an external switch is disposed at a dashboard assembly of the vehicle. When the external switch is pressed the latch mechanism, or the spring mechanism 10 is disengaged for open the lid of the vehicle.
[0005]
However, a major concern in the conventional means and method of opening the lid member is that the lid member can be opened by individual. For example, even unintended user can accidently open the lid by pushing the lid or pressing the external switch which is easily accessible. The unintended user is the 15 one who does not intend to open the lid member. More particularly, effortless access for opening the lid of an electric or plug-in hybrid vehicle by any random person poses significant security and safety risks. One of the primary concerns is unauthorized access to the vehicle's electrical components and the charging infrastructure. If the lid can be easily opened by anyone, there is a heightened risk 20 of malicious tampering, theft, or vandalism. Unintended access could lead to potential damage to the charging port, connectors, or even the vehicle's electrical system, disrupting the charging process and potentially rendering the vehicle inoperable. Moreover, unintended access to the charging infrastructure poses a safety risk, as individuals with malicious intent could tamper with electrical 25 components, creating hazards such as short circuits or electrical fires.
[0006]
Further, the cover member of the lid member is connected such that it can cover the charging terminals of the charging port or the components of the ingress port. However, it is observed that due to prolonged usage of the vehicle, or while the vehicle is operating on a rugged road, the cover member tends to vibrate or 30
4
loosen, due to which the charging terminals or the internal components of the
ingress port is exposed to dust, water or any other foreign elements.
[0007]
To overcome the above challenges, it is crucial to ensure secure opening of the lid such that the lid can be opened by an intended user, however effortless or unintended opening of the lid by the user is hindered or prevented. The intended 5 user is a person who intends to open the lid member. This not only protects the vehicle and its components but also contributes to the overall safety of the electric vehicle technology and safety of the surrounding of the vehicle.
[0008]
Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of 10 described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.

The aforesaid and other advantages of the present subject matter would be described in greater detail in conjunction with the figures & embodiment in the following description.
[00031]
Figure 1 illustrates a rear view of a portion of a vehicle comprising a lid actuating assembly (100) as per an embodiment of the present invention. As per an 5 embodiment, the vehicle comprises an ingress port (102), such as a charging port for an electric or hybrid vehicle (not shown), and a fuel inlet port for a conventional IC engine vehicle. For eliminating accidental or unintended opening of the lid member (104) by any unauthorized person, the vehicle includes the lid actuating assembly (100) for opening and closing of the lid member (104), the vehicle 10 includes the lid actuating assembly (100). The vehicle includes a frame assembly which provides structural support to the vehicle and mounting of other vehicle components. The frame assembly comprises a head tube (101), a left side frame (103), and a right-side frame (not shown). The left side frame and the right-side frame extends from the headtube towards the rear portion of the vehicle. The lid 15 actuating assembly (100) is disposed in between the left side frame (103), and the right-side frame.
[00032]
Figure 2 illustrates a side view of a portion of a vehicle comprising a lid actuating assembly (100) as per an embodiment of the present invention. Figure 3 illustrates an enlarged side view of a portion of a lid actuating assembly (100) as 20 per an embodiment of the present invention. Figure 4 illustrates a side view of a lid actuating assembly (100) as per an embodiment of the present invention. The Figure 2, the Figure 3 and Figure 4 are described together for sake of brevity and comprehensive explanation. The lid actuating assembly (100) comprises the lid member (104), a junction assembly (202), and an actuator member (206). The lid 25 member (104) covers at least a portion of the ingress port (102) of the vehicle. The lid actuating assembly (100) receives power from a power unit (208) of the vehicle. As per an embodiment, the power unit (208) is a battery unit of the vehicle. As per yet another embodiment, the power unit (208) is an auxiliary battery unit of the
9
vehicle, which enable the lid actuating
assembly (100) to be activated even while the vehicle ignition is in OFF condition.
[00033]
The junction assembly, the junction assembly (202) comprises a junction member (204); one or more coupling members (204a, 204b, 204 c) which extends from the junction member (204). More particularly, the one or more coupling 5 members (204a, 204b, 204 c) comprises a first coupling member (204a); a second coupling member (204b), and a third coupling member (204c). As per an embodiment, one or more coupling members (204a, 204b, 204 c) are cables or wires which extend from the junction member (204). The lid member is coupled to the junction assembly (202) by the first coupling member (204a) at a first portion (302) 10 of the junction member (204). On the other hand, and the actuator member (206) is coupled with the junction assembly (202) by the second coupling member (204b) at a second portion (304) of the junction member (204). As per an embodiment, the junction member (204) is a polygon shaped structure and the first portion (302), and the second portion (304) are one of the edges of the polygon structure. For example, 15 the first portion (302) and the second portion (304) are disposed laterally opposite to each other. The junction assembly (202) is disposed between the lid member (104) and the actuator member (206) when the vehicle is viewed in side view. Further, the third coupling member (204c) extends from the junction member (204) to the second portion (304) of the junction member (204). As per an embodiment, 20 the third coupling member (204c) is a freely hanging cable which can be accessed by from a cut out portion (not shown) of the vehicle. For example, the user can mechanically operate the third coupling member (204c) by pulling it through a cut out portion (not shown) of the vehicle.
[00034]
Furthermore, the junction assembly (202) also comprises a bottom member 25 (306). The bottom member (306) supports the junction member (204). More particularly, the bottom member (306) comprises a guiding structure (306a), for example guiding rails. The junction member (204) is supported on the bottom member (306) through the guiding structure (306a). The guiding structure (306a) enables sliding of the junction member (204) on top of the bottom member (306). 30
10
Furthermore, the
actuator member (206) comprises a motor (not shown), an actuator spring (not shown), and the actuator member (206) is configured to be connected to a control unit (not shown). The actuator member (206) receives an input signal from one or more electronic units (not shown). For example, the one or more electronic units are personal device equipment (PDE) and an electronic switch on 5 the vehicle. As per an embodiment, the electronic switch is configured to send the input signal only while the ignition of the vehicle is in ON condition. Thus, when a user intends to operate the lid member (104) by opening it, a mechanical force i.e., a pulling force is exerted on the junction member (204) by at least one of the second coupling member (204b) and the third coupling member (204c). The pull force on 10 the junction member (204) slides the junction member on the guiding structure (306a) away from the lid member (104), which eventually exerts a force on the first coupling member. Thus, when the first coupling member (204a) experiences a force a spring mechanism (not shown) or the latch mechanism (not shown) of the lid member (104) is disengaged and the lid member (104) is opened. The polygon 15 shaped structure of the junction member (204) provides an anti-rotation effect while the junction member (204) slide on the guiding structure (306a). The detailed explanation of the lid actuating assembly 's (100) method is provided in the subsequent descriptive paragraph.
[00035]
Figure 5 illustrates a flow chart of actuating the lid member by the lid 20 actuating assembly (100) as per an embodiment of the present invention. The process of the lid actuating assembly (100) starts at step (502). There could be two states i.e., when the vehicle ignition is in OFF condition, and the while the vehicle ignition is in ON condition, in which a user can intend to open the lid member (104) of the vehicle. If the vehicle is in OFF condition at step (504), the user can enable 25 the operation of the lid member (104) through two options as per step (506). The first option is that the user can transmit the input signal to the actuator member (206) via the control unit through a personal device equipment (PDE) such as a mobile phone. On the other hand, the second option is that the user can mechanically operate the third coupling member (204c) by accessing it from the 30 cut-out portion of the vehicle. If the vehicle ignition is in ON condition, the user
11
can transmit the input signal to the
actuator member (206) through the personal device equipment, or the electronic switch (not shown) on the vehicle at step 516.
[00036]
The third coupling member (204c) can be operated by the user at all vehicle conditions for opening the lid member (104). If the user, mechanically operate the third coupling member (204c), for example, if the user pulls the third coupling 5 member (204c) the junction member (204) experiences a pull force which enables sliding of the junction member (204) on the guiding structure (306a) away from the lid member (104), which eventually exerts a force on the first coupling member (204a), thereby the lid member (104) is opened if the lid member (104) is in closed position as per step (518). 10
[00037]
However, if the user transmits the input signal to the control unit, the control unit determines if a state of charge (SOC) of the power unit (208) is below a predefined threshold value. For example, as per an embodiment the predefined threshold value range between 1-25% of the maximum power of the power unit (208). If the state of charge (SOC) of the power unit (208) is below the predefined 15 threshold value, for example the SOC of the power unit (208) is 10%, the actuator member (206) will not be actuated or activated. Thus, the user can mechanically operate the third coupling member (204c) by accessing it from the cut-out portion of the vehicle. However, if the state of charge (SOC) of the power unit (208) is below the predefined threshold value, for example the SOC of the power unit (208) 20 is 30%, once the actuator member (206) receives the input signal, the actuator member (206) is actuated or activated at step (512). After the actuator member (206) is activated, the motor of the actuator member (206) starts operating which exerts a force on the actuator spring, which eventually exerts a mechanical pull in the second coupling member (204b) at step (514). Similar, to the third coupling member 25 (204c), once the second coupling member (204b) experiences a mechanical force, the mechanical force enables the lid member (104) to be opened if the lid member (104) is in closed position as per step (518). Once the lid member (104) is opened the process of opening the lid member (104) by the lid actuating assembly (100) is ended at step (520). 30
12
[00038]
Advantageously, the present invention provides a lid actuating assembly (100) which is enabled to open the lid member (104) automatically when the intentional user sends the input signal through a PDE or by the electronic switch which can operate only when the vehicle ignition is in ON condition. While the present invention also enables that the lid actuating assembly (100) can open the lid 5 by mechanically operating the third coupling member (204c), through a cut out portion on the vehicle. Thus, the present invention ensures that only authorised users can open the lid member (104) of the vehicle, while ensuring that accidental or unintentional opening of the lid member (104) is eliminated. Thus, the present invention successfully prevents unintentional access to the ingress port (102), 10 connectors, or even the vehicle's electrical assembly (100), which can disrupt the charging process and potentially rendering the vehicle inoperable. Moreover, unintended access to the charging infrastructure poses a safety risk, as individuals with malicious intent could tamper with electrical components, creating hazards such as short circuits or electrical fires. 15
[00039]
Further advantageously the third coupling member (204c) can be accessed by the authorised user through a cut out portion of the vehicle at all vehicle conditions. Thus, while the SOC of the power unit (208) is below a predefined threshold, which is unable to power the lid actuating assembly (100) the user can mechanically access the third coupling member (204c) to open the lid member 20 (104). Further, positioning of the third coupling member (204c) through the cut-out portion prevents any accidental access or opening of the lid member (104).
[00040]
Further advantageously, the bottom member (306) comprises a guiding structure (306a) which enables smooth sliding or movement of the junction member (204). This ensures to enable opening of the lid member (104) smoothly without 25 unwanted frictions. Moreover, the polygon-shaped structure of the junction member (204) exhibits an anti-rotation effect while sliding on a guiding structure (306a) due to its inherent geometric properties. Unlike a simple cylindrical or round shape, a polygonal structure, with its flat surfaces or edges, introduces resistance to rotational movement. In other words, the geometric configuration of a polygon, 30
13
with its multiple sides and angular characteristics, enhances stability and reduces
the likelihood of unwanted rotation.
