SIDE WIND SCREEN AND REAR VIEW MIRROR WIPERS

FIELD OF INVENTION

This invention generally related to Side Wind Screen and Rear View mirror a wiper which is to wipe and clean the fogs and rainwater from the rear view mirrors and side windscreen of automotive vehicles without manual effort during inclement weather conditions. This wiping system comprises wiper motor, servo motor, magnets, wiper arms and wiping blades.

PRIOR ART

Driving cars or trucks during inclement weather like raining or fog is difficult to clear rainwater, snow and other form of dusts while driving in highway or adventurous road conditions. Nowadays windshield wipers are mounted in front and back of vehicle to clear rainwater and snows from rear and front windshield. However, wipers or any cleaning for outside rearview mirrors have not become popular even though the safety features of such devices are self-evident.

The drivers are cleaning the side windshield and rear view glass by cloth manually while driving, which lead fatal accidents.

Previously the car companies are developing some mechanisms for wiping rainwaters in the rearview mirror but such mechanisms are not popular because of maintenance problem and non-aesthetic looks.

OBJECT OF THE INVENTION

Object of this invention is to forefront issues in cleaning the rear view mirror, side windscreen and its associated difficulties. Windscreen wipers are in use today to wipe of the rain waters from the front and back windshields. If the rear view mirror become fogged or covered with rain or the like, it is difficult while the vehicle is traveling to clean such mirror or mirrors, and they become useless and this situation is dangerous and creates a safety problem. The problem of providing a clean rear view mirror under rainy and foggy conditions has been partially solved or overcome by applicants improved wiper equipment as shown.
This project develops a state of art attachments to clean rearview mirror and side windscreen of the vehicle.

The invention has been explained in relation to specific embodiment. It is referred that the foregoing description is only illustrative of the present invention and it is not intended that the iiivention be limited or restrictive thereto. Many other specific embodiments of the present invention will be apparent to one skilled in the art from the foregoing disclosure. All substitution, alterations and modifications of the present invention, which come within the scope of the following claims, are to which the present invention is readily susceptible without departing from the spirit of the invention.

The scope of the invention should therefore be determined not with reference to the above description but should be determined with reference to appended claims along with full scope of equivalents to which such claims are entitled.

Side wind screen unit is fixed on the side of driver door (2) of the car (1) In the Side wind screen unit, PDMC motor (7) i% connected to rack and pinion gear (10) using the spindle of motor shaft (8) for transferring motor power to the rack and pinion gear. The rack and pinion gear changes the rotational motion to linear motion, which actuates the piston cylinder (6); the Piston is design to up and down movement in the Piston Cylinder. The limit switch (11) controls the directional movement of the piston. The magnetic wiper holder (9) is fixed on the piston cylinder, which is in contact with the wind screen to wipe of the dust, fog, mist and rain water from the wind screen.

Car side mirror unit (4) is fixed on the side of the car, and the EDC Box (12) is fixed behind the rear view mirror unit, which consists of power supply, protection circuit, relay, with interlock switch. It is used to control the wiper up and down automatically with the cyclic timer in side mirror cleaning. The EDC unit is connected to the stepper motor (13) which actuates and rotational motion is controlled by the gear mechanism (14) and transfers the rotational power to pulley (15) by belt. The pulley is in contact with the wiper holder (16) and move the wiper holder by up and down direction using Wiper Piston (3) which is holding the car side mirror wiper (5) to clean dust, fog, mist and rain water from the rear glass (17).

The whole side mirror unit is protected by the cover (18) from external weather and corrosions.

Detailed Description of the Invention with Reference to Drawing
1. Car is a wheeled, self-powered motor vehicle used for transportation. Most definitions of the term specify that cars are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods.

2. Car Driver door is situated by the side of driver seat, during driving
at rain season the side door mirror began blind spots due to freezing water in glass. There will no clear way to right or left turn. To reduce the risk of driving to design the glass cleaning wiper in the project.

3. Wiper Piston is holding the cleaning wiper toward the side mirror
. and wind screen. The Piston is design to up and down movement
in the Piston Cylinder.

4. Car Side Mirror is situated in side front of the car, which is mainly

used for rear view vehicle movement.
5. Car side mirror wiper is the rubber material blade, which wipe off
the dust, fog and water from the side mirror

6. Piston Cylinder is used to guide the piston movement freely in
cylinder

7. PMDC Motor is extensively used where small dc motors are
required and also very effective control is not required, such as in automobiles starter, No input power in consumed for excitation which improves efficiency of dc motor. It is Cheaper and economical for fractional kW rated applications.

8. Motor Shaft is connecting the high speed motor with gear box
which reduce the speed and increase the torque of wiper movement.

9. Magnet wiper holder has magnetic property which is used to hold
the wiper blade.

10. Rack and pinion combination is used to change the rotational movement to linear movement, where the rotation of a shaft powered by hand or by a motor is converted to linear motion. The rack carries the full load of the actuator directly and so the driving pinion is usually small, so that the gear ratio reduces the torque, may still be substantial and so it is common for there to be a reduction gear immediately before this by either a gear or worm gear reduction. Rack gears have a higher ratio, thus require a greater driving torque, than screw actuators.

11. Limit Switch is used for controlling as part of a control system, as a safety interlocks. A limit switch is an electromechanical device that consists of an actuator mechanically linked to a set of contacts. The device operates the contacts to make or break an electrical connection. Relay wiff be directly controlled by the contacts of an Wiper Motor, the limit switch will be wired through a control relay, a motor contactor control circuit, or as an input to a programmable logic controller.

12. Electrical Drives Control (EDC) box consisting of power supply, protection circuit, relay, with interlock switch. It is used to control the wiper up and down automatically with the cyclic timer in side mirror cleaning.

13. Stepper Motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. - The stepper motor is an electromagnetic device that converts digita.1 pulses into mechanical shaft rotation. Advantages of step motors are low cost, high
. reliability, high torque at low speeds and a simple, rugged construction that operates in almost any environment.

14. Gear Mechanism inside the wiper unit is used the control the speed of the rotation, torque and direction of the wiper.

15. Pulley is a wheel on an axle that is designed to support movement and change of direction wiper movement using belt along its circumference

16. Wiper Holder is used to hold the wiper rigidly

17. Rear glass is a Convex mirror which is used for rear view enlarge

18. Cover is designed with weather proof material which covers the whole side mirror unit.

ADVANTAGES OF THE INVENTION

1. Equipment wipes off the fogs and rain water from rear view mirror without manual effort by using hand cloths.

2. The equipment wipes off the fogs and other obstacles from the side windscreen for clear visibility to rearview mirror.

3. Exclusively designed to easily mount and dismount from the vehicle.

4. Extinguisher can be moved to desired place to put off the fire as it is supported by trolley and lifting arrangement

5. Construction cost is very economic.
