Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a plug-type fully 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 fully waterproof structure with a plug for square motors, which addresses the problem that existing square motors are prone to moisture.

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

[0005] A fully waterproof structure for a square motor includes two waterproof sleeves: one sleeve is fitted over the end of the square motor for inserting a terminal block, and the other sleeve is fitted over the end of the square motor having an output shaft; the two waterproof sleeves are interlocked; each waterproof sleeve has a shaft through hole at its bottom, and during installation, the output shaft of the square motor passes through the entire square motor and through the shaft through hole of one waterproof sleeve, while the shaft through hole of the other waterproof sleeve is plugged with a waterproof plug.

[0006] In a preferred embodiment of this utility model, a plurality of annular grooves are provided on the inner wall of one waterproof sleeve, and a plurality of annular protrusions are provided on the outer wall of another waterproof sleeve. Each annular protrusion is embedded in a corresponding annular groove to form the interlocking structure to increase waterproofness.

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

[0008] In a preferred embodiment of the present invention, the waterproof plug has a cover portion and a plug portion. The outer diameter of the cover portion is larger than the outer diameter of the plug portion and larger than the inner diameter of the shaft through hole. During installation, the plug portion of the waterproof plug is inserted into the shaft through hole of a waterproof sleeve through which the output shaft of the square motor does not pass.

[0009] In a preferred embodiment of this utility model, the edge of the cover portion is beveled.

[0010] In a preferred embodiment of the present invention, the outer peripheral surface of the plug body is wavy.

[0011] In a preferred embodiment of the present invention, an annular protrusion is provided on the plug body portion away from the cover body portion to prevent the waterproof plug from being easily pulled out of the shaft through hole.

[0012] By employing the above technical solution, this utility model utilizes two waterproof sleeves and a fully enclosed square motor structure. With the added benefits of elasticity and friction, its waterproof capability is significantly enhanced. It solves the waterproofing problem of square motors and boasts advantages such as simple structure, convenient installation, ease of production, fewer steps, and greatly reduced production costs. During installation, a waterproof plug is inserted into the shaft perforation hole of one of the waterproof sleeves that is not passed through by the output shaft of the square motor, further improving the waterproofing effect.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] See Figures 1 to 3 The figure shows a fully waterproof structure for a square motor, comprising two waterproof sleeves 100 and 300. One waterproof sleeve 300 is fitted onto the end of the square motor 200 for inserting the terminal block, and the other waterproof sleeve 100 is fitted onto the end of the square motor 200 having an output shaft 210. The two waterproof sleeves 100 and 300 are interlocked in an alternating structure. Specifically, several annular grooves 310 are provided on the inner wall of one waterproof sleeve 300, and several annular protrusions 110 are provided on the outer wall of the other waterproof sleeve 100. The annular grooves 310 and the annular protrusions 110 are both matching semi-circular shapes.

[0018] Each annular protrusion 110 is embedded in a corresponding annular groove 310, forming an interlocking structure. The use of two waterproof sleeves 100 and 300 and a fully enclosed square motor 200 structure, combined with elasticity and friction, enhances its waterproof capabilities.

[0019] Each waterproof sleeve 100 and 300 has a shaft through hole 120 and 320 at its bottom. During installation, the output shaft 210 of the square motor 200 passes through the entire square motor 200 and through the shaft through hole 120 of one waterproof sleeve 100. The shaft through hole 320 of the other waterproof sleeve 300 is blocked by a waterproof plug 400.

[0020] The waterproof plug 400 has a cover portion 410 and a plug portion 420. The outer diameter of the cover portion 410 is larger than the outer diameter of the plug portion 420 and larger than the inner diameter of the shaft through holes 120 and 320. The edge of the cover portion 410 is beveled. After installation, due to the small stress area, it will not easily fall off, which facilitates production. The outer peripheral surface of the plug portion 420 is wavy.

[0021] During installation, the plug body 420 of the waterproof plug 400 is inserted into the shaft through hole 320 of a waterproof sleeve 300 through which the output shaft 210 of the square motor 200 does not pass. An annular protrusion 430 is provided on the plug body 420 away from the cover body 420 to prevent the waterproof plug 400 from being easily pulled out of the shaft through hole 320.
