Description

Technical Field

[0001] The present application relates to the field of motors, and more specifically to an anti-detachment structure of a reduction gearbox end cover of a window-lifting motor and a disassembly device thereof. Background Art

[0002] During long-term operation of the motor, the upper cover often becomes loose or even falls off, causing the motor to be not waterproof or even not operate. As part of the reduction gearbox, it is crucial to ensure that the upper cover fits tightly with the gear box to prevent the upper cover from falling off, thereby causing other parts inside the reduction gearbox to fall off.

[0003] There are two structures currently used in the market. One is a plastic cover with a hook structure with a long hook, which is easy to break during transportation and storage. There is also a cover without a hook that is ultrasonically welded and cannot be disassembled. The other is a metal cover that hooks the gear box with the help of a machine, but due to structural limitations, it is impossible to achieve multiple uniform clamping points, resulting in uneven force on the sealing circumference, which is prone to water leakage. 1. Compared with the method of hooking the gear box with a long cover of the same material, the long hook of the cover is easy to break the foot during transportation and storage. The cover of this structural design has no hook, which is convenient for storage and suitable for small motors. 2. Compared with other materials that use machines to squeeze and hook the gear box around the cover, which is heavy and complicated to install, this structural design only needs to open the skirt of the cover to allow the cover buckle to be assembled. It is simple to install and light in weight, and is suitable for lightweight and low-cost motors. The present invention is proposed to solve the above problems. The purpose is to use a simple and effective method to achieve a tight fit between the gear box and the cover to prevent falling off, and at the same time provide a disassembly structure that is easy to disassemble the cover body, so as to facilitate the subsequent repair and maintenance of the product.
