Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a semi-waterproof structure for a square motor. Background Technology

[0002] The square motors used in car door handles are easily affected by the external environment. Air humidity and seasonal changes can easily cause water to enter the square motor and cause it to become damp, leading to malfunctions. Therefore, how to waterproof square motors has always been an urgent problem for motor manufacturers to solve. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a semi-waterproof structure for square motors, which addresses the problem that existing square motors are prone to moisture, thereby solving the waterproofing problem of square motors.

[0004] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0005] A semi-waterproof structure for a square motor includes: a waterproof sleeve fitted over one end of the square motor for inserting a terminal block; two annular protrusions are provided on the inner wall of the waterproof sleeve, and two annular grooves are correspondingly provided on the housing of the square motor, with each annular protrusion embedded in the corresponding annular groove to prevent the waterproof sleeve from falling off and to increase waterproofness.

[0006] In a preferred embodiment of this invention, a terminal hole is provided on the side wall of the waterproof sleeve. The terminal passes through the terminal hole and is inserted into the square motor. The terminal hole consists of a cylindrical hole and a flared hole that are interconnected. The cylindrical hole is located on the outer bottom of the waterproof sleeve, and the flared hole is located on the inner bottom of the waterproof sleeve. The smaller diameter end of the flared hole communicates with the cylindrical hole. Because the terminal hole is smaller on the outside and larger on the inside, the plug terminal is tightly wrapped, thereby achieving the purpose of waterproofing.

[0007] In a preferred embodiment of this utility model, the annular groove and the annular protrusion are both adapted semi-circular shapes.

[0008] By adopting the above technical solution, this utility model can solve the waterproofing problem of square motors, and has the advantages of simple structure, convenient installation, easy production, fewer processes, and greatly reduced production costs. Attached Figure Description

[0012] Figure 4 This is a schematic diagram of the structure of the waterproof sleeve of this utility model. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] See Figures 1 to 4 The figure shows a semi-waterproof structure for a square motor, including: a waterproof sleeve 100, which is fitted onto one end of the square motor 200 for inserting a terminal block.

[0015] Two annular protrusions 110 are spaced apart and parallel on the inner wall of the waterproof sleeve 100, and two annular grooves 211 are correspondingly provided on the housing 210 of the square motor 200. The annular grooves 211 and the annular protrusions 110 are both matching semi-circular shapes.

[0016] After the waterproof sleeve 100 is fitted onto the end of the square motor 200 used for inserting the terminal block, each annular protrusion 110 is embedded in the corresponding annular groove 211 to prevent the waterproof sleeve from falling off and also to increase waterproofness.

[0017] A terminal hole 130 is provided on the side wall 120 of the waterproof sleeve 100. The terminal (not shown in the figure) passes through the terminal hole 130 and is inserted into the square motor 200.

[0018] The terminal block perforation 130 consists of a cylindrical hole 131 and a flared hole 132 that are interconnected. The cylindrical hole 131 is located on the outer side of the side wall 110 of the waterproof sleeve 100, and the flared hole 132 is located on the inner side of the side wall 120 of the waterproof sleeve 100. The smaller diameter end of the flared hole 132 communicates with the cylindrical hole 131. Because the terminal block perforation 130 is smaller on the outside and larger on the inside, the plug terminal is tightly wrapped, thereby achieving the purpose of waterproofing.
