The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention. Furthermore, it should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation, not limitation. In the present invention, unless stated to the contrary, the terms of orientation such as "upper" and "lower" used herein generally refer to the upper and lower positions of the device in actual use or operation, specifically, the direction of the drawing in the drawings; while "inner" and "outer" are with respect to the outline of the device.
Referring to fig. 1 and 2, an embodiment of the present invention provides a waterproof and dustproof sealing structure for a motor, including a motor 1 and a cooler 2 installed on the top of the motor 1, an air inlet 3 and an air outlet 4 are formed on the top of the motor 1 and the bottom of the cooler 2, and the cooler 2 is thermally connected to the inside of the motor 1 through the air inlet 3 and the air outlet 4, so that heat generated by an internal heating element of the motor 1 can be dissipated to the surrounding environment by using the cooler 2.
In order to improve the sealing performance between motor 1 and cooler 2, the embodiment of the utility model provides a surround in the periphery of air intake 3 and air outlet 4 and be provided with two at least protruding circles 5, adjacent protruding circle 5 intervals set up in order to inject and lie in sealed recess 6 between the two, the embedded annular elastic sealing circle 7 that is equipped with of sealed recess 6, elastic sealing circle 7 can encircle the periphery that sets up at air intake 3 and air outlet 4, thereby inject an inclosed heat transfer space between motor 1 and cooler 2, can effectively prevent the rainwater, in the dust etc. gets into motor 1, also can avoid motor 1 decompression simultaneously.
When the volume of the motor 1 is small, only two convex rings 5 can be arranged, a sealing groove 6 is formed between the two convex rings 5 at intervals, and an elastic sealing ring 7 can be arranged on the peripheries of the air inlet 3 and the air outlet 4 through the sealing groove 6 to realize sealing; when the size of the motor 1 is large, three or more than three convex rings 5 can be arranged according to the size of the top of the motor 1, and a plurality of sealing grooves 6 which are concentrically distributed are formed by utilizing the interval between two adjacent convex rings 5, so that a plurality of elastic sealing rings 7 which are nested can be arranged on the peripheries of the air inlet 3 and the air outlet 4, and sealing is enhanced. It can be understood that the convex ring 5 and the elastic sealing ring 7 can be arranged at the bottom of the cooler 2 or at the top of the motor 1, and it is only necessary to ensure that the elastic sealing ring 7 can be arranged around the peripheries of the air inlet 3 and the air outlet 4 when the cooler 2 and the motor 1 are installed together. For reference, the convex ring 5 in the embodiment is formed by directly welding a strip-shaped flat steel on the top of the motor 1, so that the installation is convenient.
