Description

Technical Field

[0001] This utility model relates to the field of starter end cover technology, specifically to a starter end cover with a waterproof structure. Background Technology

[0002] The starter motor is primarily used to start a car by powering the engine. The increased speed of the starter motor forces out a one-way valve, which then engages with the engine, thus increasing the engine speed and assisting in starting. The starter motor includes a drive end cap, which is prone to water accumulation and requires a drainage structure. As existing technology, Chinese patent CN217115799U proposes a starter motor end cap, including an end cap body. Its features include: a flexible water-absorbing structure that releases water upon compression; a water-squeezing structure for compressing the flexible water-absorbing structure; and a drainage structure for expelling water from the flexible water-absorbing structure after compression. While this solution addresses the issue of water retention in the drainage holes, water entering the end cap body tends to accumulate on the inner bottom wall, and some water may not be able to flow into the drainage holes, resulting in retention. Further improvement is needed. Utility Model Content

[0003] The purpose of this invention is to provide a starter end cover with a waterproof structure to solve the problems mentioned in the background art.

[0004] To solve the above technical problems, this utility model adopts the following technical solution: a starter end cap with a waterproof structure, wherein the end cap body is provided with a flexible water-absorbing structure that can release water by squeezing, a water-squeezing structure for squeezing the flexible water-absorbing structure is provided on the end cap body, and a drainage structure is provided on the end cap body for the water in the flexible water-absorbing structure to be squeezed out and discharged from the end cap body after being squeezed out, the drainage structure including a plurality of drainage holes provided on the bottom wall of the end cap body, the inner bottom of the end cap body is provided with an annular groove, and the inner wall of the end cap body is provided with a removable waterproof plate. The waterproof plate and the groove are spaced apart vertically. The waterproof plate has several water guide holes that run vertically through it, and the several water guide holes and several drainage holes are arranged one-to-one. It also includes a squeegee. The length of the squeegee is the same as the difference between the inner and outer diameters of the groove. The lower end of the squeegee can slide circumferentially with the bottom wall of the groove. The inner wall of the end cap body has an annular opening. The cross-section of the opening is L-shaped and extends through the bottom of the end cap body. The squeegee is connected to an L-shaped push handle. The lower end of the push handle extends out of the opening and can slide circumferentially within the opening.

[0005] By adopting the above technical solution, when water enters the interior of the end cover body, a waterproof plate is installed to block the water. The blocked water can fall directly into the drain hole through the water guide hole for discharge. If some water cannot be guided to the drain hole and stagnates on the bottom wall of the groove, the push handle is driven to slide circumferentially in the opening, thereby causing the lower end of the wiper blade to slide circumferentially with the bottom wall of the groove. The wiper blade pushes the stagnant water into the drain hole for discharge, thereby reducing water accumulation, extending the service life of the starter end cover, and achieving a better waterproof effect.

[0006] As a further optimization of this utility model, the waterproof plate is provided with an inclined water guide plate around the top of the water guide hole.

[0007] By adopting the above technical solution, a water guide plate is installed to facilitate the water flow into the water guide hole.

[0008] As a further optimization of this utility model, the inner wall of the opening is provided with a sliding groove, and the push handle is provided with a slider that is adapted to slide circumferentially with the sliding groove.

[0009] As a further optimization of this utility model, the inner wall of the end cap body is provided with a plurality of locking blocks, and the bottom of the waterproof plate is provided with a locking groove, the locking groove and the locking blocks being connected by a snap-fit ​​mechanism.

[0010] As a further optimization of this utility model, the sidewall of the groove is symmetrically provided with a pair of protruding limiting blocks, and the wiper blade is provided with two of them, which are located on both sides of the line connecting the pair of limiting blocks.

[0011] By adopting the above technical solution, two wiper blades can be set up to wipe water simultaneously, thereby improving the wiping efficiency. A limit block is set up to restrict the circumferential movement path of the wiper blades and prevent the two wiper blades from colliding.

[0012] The beneficial effects of this utility model are as follows: When water enters the interior of the end cover body, a waterproof plate is installed to block the water. The blocked water can fall directly into the drain hole through the water guide hole for discharge. If some water cannot be guided to the drain hole and stagnates on the bottom wall of the groove, the push handle is driven to slide circumferentially in the opening, thereby driving the lower end of the wiper blade to slide circumferentially with the bottom wall of the groove. The wiper blade pushes the stagnant water into the drain hole for discharge, thereby reducing water accumulation, extending the service life of the starter end cover, and achieving a better waterproof effect.
