Description

Technical Field

[0001] The utility model relates to the technical field of automobile motor gear box structures, in particular to an automobile motor gear box structure. Background Art

[0002] The small motor used in the existing automobile electric window requires that the motor not only provide good glass rising and falling functions, but also has waterproof and dustproof functions; the waterproof function requires the gear box to be sealed, and when the gear box is sealed, it is necessary to seal and connect through the gear box, the upper cover and the O-ring, and the sealing connection is to achieve ideal sealing performance while saving costs; there are two existing sealing methods: one is the upper and lower sealing structure of the O-ring. When connected, the gear box has poor sealing performance due to the uneven pressing force between the upper cover and the gear box, which will cause water leakage and dust ingress; the other is the integral injection molding of the sealing ring and the upper cover. Although this structure has good sealing performance, it requires secondary molding of the upper cover, so the process is relatively complicated and the cost is relatively high.

[0003] A motor gear box sealing structure, an automobile electric window motor and an automobile are disclosed in the Chinese utility model patent application disclosure specification CN216742744U. Although the motor gear box sealing structure, the automobile electric window motor and the automobile have the advantages of effectively sealing and dustproofing, and convenient molding and processing, the motor gear box sealing structure, the automobile electric window motor and the automobile still have disadvantages: First, the motor gear box sealing structure, the automobile electric window motor and the automobile are packaged and connected in the form of upper cover clamping. In actual use, the connection strength of the lock may not be guaranteed after a period of use, which may cause problems with the upper cover being poorly sealed; Second, the motor gear box sealing structure, the automobile electric window motor and the bottom gear box of the automobile are often arranged as an integral whole. In actual use, when the gears are disassembled and assembled, they are installed on the inner bottom of the gear box, so the operation may not be very convenient during installation and subsequent maintenance and replacement.
