Problems solved by technology

[0007] The purpose of the present invention is to provide a wiper motor end cover using chrome-plated anti-rust technology, so as to solve the problem of the time-consuming screwing between the wiper motor end cover and the wiper motor in the prior art, and when a thread slips , the entire thread is declared scrapped, and a wiper motor end cover that uses a thread segment structure for screw connection is designed. The segmental design mode can ensure that even if there is a thread slippage, the entire The situation that the screw connection part is scrapped occurs; because the thread sections do not interfere with each other, when a certain thread slips in a certain section, the entire screw connection part will not be scrapped; and the use of straight threads instead of ordinary threads makes the screw connection The part is more stable and there will be no deformation

Embodiment 1

[0026] A wiper motor end cover using chrome-plated anti-rust technology, which solves the problem that in the prior art, it takes a long time to screw the connection between the wiper motor end cover and the wiper motor, and when there is a trace of thread slippage, the entire thread will be announced. For the inadequacy of scrapping, we designed a wiper motor end cover that uses a threaded segment structure for screwing. Its segmental design mode can ensure that even if there is a thread slippage, the entire screwed part will not be scrapped. situation occurs; because the thread segments do not interfere with each other, when a certain thread slips in a certain section, the entire screw connection will not be scrapped; and the use of straight threads instead of ordinary threads makes the screw connection more stable and There will be no deformation, such as figure 1 , figure 2 As shown, it includes the wiper motor end cover body that has been treated with plating and anti-r...

Embodiment 2

[0030] This embodiment is further optimized on the basis of the above-mentioned embodiments. Further, in order to better realize the present invention, the connection between the wiper motor and the end cover of the wiper motor can be more in line with mechanical stability, such as figure 1 , figure 2 As shown, the following structure is particularly arranged: the straight threaded sections 6 are 4 sections, and the 4 straight threaded sections 6 are evenly distributed along the circumference of the outer cylinder 7 of the end cover of the wiper motor.

Embodiment 3

[0032] This embodiment is further optimized on the basis of the above-mentioned embodiments, further to better realize the present invention, and further ensure a stable connection with the stator or rotor in the wiper motor, such as figure 1 , figure 2 As shown, the following structure is particularly arranged: the wiper motor end cover body is also provided with a wiper motor end cover inner cylinder 4, and the wiper motor end cover inner cylinder 4 and the wiper motor end cover outer cylinder 7 is concentrically arranged on the bottom 5 of the end cover of the wiper motor; on the inner wall of the inner tube 4 of the end cover of the wiper motor, a circle of bosses 3 which are geometrically evenly distributed is arranged.

Abstract

The invention discloses a wiper motor end cover employing a chrome-plating rust-proof technology. The wiper motor end cover comprises a wiper motor end cover body, wherein the inside and the outside of the wiper motor end cover body are treated by the chrome-plating rust-proof technology; the wiper motor end cover body comprises a wiper motor end cover bottom and a wiper motor end cover barrel; at least two segments of straight thread segments which are not connected with one another are arranged on the inner wall of the wiper motor end cover barrel; the crest widths of the straight thread segments are 1.1-1.5mm; a through hole is formed in the center of the wiper motor end cover bottom; and four straight thread segments are arranged and are evenly distributed along the circumferential direction of the wiper motor end cover barrel. By a segment design mode, the condition that the whole threaded part is not scrapped even if one segment of thread slips can be ensured. Various thread segments are not interfered with one another, so that when one segment of thread slips, the whole threaded part is not scrapped; and an ordinary thread is replaced with a straight thread, so that the threaded part is relatively stable; and the problem of deformation is avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a wiper motor end cover using chrome-plated anti-rust technology. Background technique [0002] The wiper motor is driven by the motor, and the rotation of the motor is converted into the reciprocating motion of the wiper arm through the linkage mechanism, so as to realize the wiper action. Generally, the wiper can work when the motor is turned on. By selecting high-speed and low-speed gears, it can change The current of the motor controls the speed of the motor and then the speed of the scraper arm. [0003] The wiper of the car is driven by the wiper motor, and the potentiometer is used to control the motor speed of several gears. [0004] There is a small gear transmission enclosed in the same housing at the rear end of the wiper motor to reduce the output speed to the required speed. This device is commonly known as the wiper drive assembly. The output sha...
