Rearview mirror wiper for overall wiping and rearview mirror thereof

Abstract

The invention relates to a rearview mirror wiper for overall wiping and a rearview mirror thereof. The rearview mirror wiper comprises a wiper portion which is arranged on the outer surface of a mirror plate and used for overall wiping, a sliding mechanism which is arranged on the back surface of the mirror plate, enables the wiper portion to carry out up-down wiping and is provided with a sliding rail, and a driving device used for driving the sliding mechanism. The upper end and lower end of the sliding rail have limiting points and are provided with wiper position sensors which are used for sensing the up-down movement position of a sliding block. The driving device comprises a stepping motor and a toothed driving wheel arranged at the output end of the stepping motor. The rearview mirror wiper for overall wiping and the rearview mirror thereof have the beneficial effects that the structure can fill in the blank in the prior art and can overall wipe rectangular rearview mirrors like oblong or square rearview mirrors, especially for rearview mirrors of buses, trucks and the like; vertical worms are used for driving wiper bars for parallel wiping, so that the cleaning effect is improved and no dead corners are left; and the wiper structure does not affect position adjustment of the rearview mirror.

Description

technical field [0001] The invention relates to the technical field of windshield wipers for vehicles, in particular to a rearview mirror wiper and a rearview mirror which are convenient for comprehensive sweeping. Background technique [0002] Traditional wiper generally refers to a tool for simple cleaning on the front glass of a motor vehicle to prevent rainwater and other dirt from affecting the line of sight. The wiper or wiper is an essential part of the car. It is used to turn the water droplets on the car glass into a uniform water film. The uniform water film will not cause light refraction, so that the driver can get a clear vision and improve driving. Safety. At present, traditional wipers are generally installed on the surface of the front windshield or the rear windshield. They only clean up the rainwater in these two areas, and cannot clean up other important parts of the vehicle, such as the rearview mirrors on both sides of the vehicle. . [0003] When it i...

Problems solved by technology

[0006] For example, the rearview mirror wiper uses a worm to drive the gear and the connecting piece to rotate, so that the wiper swings and removes the accumulated water in the rearview mirror. The basic principle is: start the switch, and after the motor is powered on, it drives the worm at the output end of the motor to rotate, and the worm drives the rotating gear Rotate, and then drive the wiper shaft to rotate through a series of connecting rods, and finally the wiper shaft drives the wiper blade of the rearview mirror to swing to achieve the purpose of removing the rain on the mirror surface. This type of wiper device with more transmission mechanisms is adopted , requires a series of connecting rods and gears to be engaged to achieve rotation. After a long period of use, it is necessary to lubricate, replace or maintain the corresponding mechanical components. So many mechanical transmission components are difficult to achieve thorough maintenance. At the same time, these The mechanical components of the mechanical transmission rearview mirror wiper are arranged in a fixed box in order to meet the effective mechanical transmission. The mechanical components are messy and irregular, which causes great trouble for disassembly and assembly.

[0007] At the same time, it needs to be emphasized that even if it is easy to install and adjust the above-mentioned similar mechanical transmission rearview mirror wiper device, since the previous wiper adopts heating or swinging up and down brushes, the swing will always have a specific range. Therefore, these The rearview mirror wiper device cannot realize comprehensive sweeping of the rectangular rearview mirror of the bus. If the existing rearview mirror wiper is used for sweeping, blind spots and dead spots will inevitably appear. The water droplets on the blind spot will still gradually flow with the driving of the vehicle, which will inevitably blur the rearview mirror again

[0008] In addition, the previous mechanically driven rearview mirror wiper has poor controllability, which is not conducive to vertically reciprocating comprehensive sweeping without dead ends
