[0002] A motor refers to an electromagnetic device that realizes electrical energy conversion or transmission based on the law of electromagnetic induction. The motor generally includes a casing and a rotor installed in the casing. A motor front end cover is installed at the front end of the casing, and a motor rear end cover is installed at the rear end of the casing.

[0003] In the prior art, in order to ensure the heat dissipation effect of the motor, a heat dissipation port is opened on the rear end cover of the motor. However, in order to avoid damaging the overall strength of the rear end cover, a dot matrix opening is generally used. The dot matrix heat dissipation opening cannot effectively discharge the heat generated when the motor is working. Later, a heat dissipation port with a large opening was designed. However, in order to increase the strength of the rear end cover of this structure, the overall weight is too large, resulting in excessively high production costs. Utility Model Content

[0004] The utility model aims to solve the problem that the strength of the rear end cover of the motor is weakened due to the opening of the heat dissipation port in the prior art, and proposes the following technical solutions:

[0005] The motor rear end cover structure and the motor include:

[0006] A mounting cover and a support seat arranged on a surface of the mounting cover;

[0007] The support seat includes a connecting seat, the upper end of the connecting seat has reinforcing ribs in a circular array, ventilation grooves are provided between adjacent reinforcing ribs, a bearing seat is connected between the reinforcing ribs, and a bearing positioning hole is provided inside the bearing seat.

[0008] As an improvement of the above technical solution, the reinforcing ribs are overall arc-shaped structures connected to the middle bearing seat, and the reinforcing ribs are provided in multiple groups, and the cross-sectional shape and curvature radius of each group are the same.

[0009] As an improvement of the above technical solution, a snap-in groove is provided at a position of the side wall of the reinforcing rib corresponding to the ventilation groove.

[0010] As an improvement of the above technical solution, the installation cover includes a connection cover, and positioning grooves are provided at four corners of the connection cover, and installation holes are provided on both sides of the positioning grooves of the connection cover.

[0011] As an improvement of the above technical solution, a dustproof net is further installed inside the support seat, and the dustproof net includes a mounting frame, and a mesh plate is arranged inside the mounting frame.

[0012] As an improvement of the above technical solution, a non-slip adhesive strip is further provided on the surface of the installation frame, and the installation frame is fixed by inserting the non-slip adhesive strip into the inside of the clamping groove.

[0013] Another object of the present invention is to provide a motor, comprising any one of the above rear end cover structures.

[0014] Beneficial effects of the utility model:

[0015] The support base is composed of reinforcing ribs arranged in a circular array, which can further improve the overall strength, so that when a large-opening ventilation slot is opened in between, the strength of the end cover can also be guaranteed, avoiding the risk of breakage caused by one end of the motor rotor during rotation. At the same time, the ventilation slots can effectively improve the heat dissipation effect of the motor when it is working, avoiding the risk of heat generated inside the motor due to excessively high rotation speed and being unable to be discharged.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0022] Example 1

[0023] The motor rear end cover structure and the motor include:

[0024] A mounting cover 1, and a support base 2 arranged on the surface of the mounting cover 1, wherein a dustproof net 3 is also installed inside the support base 2;

[0025] The installation cover 1 comprises a connection cover 11, and positioning grooves 12 are formed at four corners of the connection cover 11, and installation holes 13 are formed at both sides of the positioning grooves 12 of the connection cover 11;

[0026] The connecting cover 11 is provided to close the end of the motor when it is installed with the motor, and the positioning groove 12 is provided to stably limit the connection during installation. At the same time, the mounting screws are installed inside the mounting hole 13 to connect with the motor, thereby improving the stability after installation and avoiding falling off due to vibration generated during the use of the motor.

[0027] The support seat 2 includes a connecting seat 21, a reinforcing rib 22 is provided in an annular array on the upper end of the connecting seat 21, a ventilation slot 23 is provided between adjacent arc-shaped reinforcing ribs 22, a bearing seat 24 is connected between the reinforcing ribs 22, a bearing positioning hole 25 is provided inside the bearing seat 24, and a clamping slot 26 is provided at a position corresponding to the ventilation slot 23 on the side wall of the reinforcing rib 22;

[0028] The connection seat 21 provided can provide excessive buffering when connected to the connection cover 11, thereby improving the strength of the connection and avoiding overall breakage caused by vibration of the motor during use. The reinforcing ribs 22 are provided in the upper annular array to further improve the overall strength, so that when a ventilation slot 23 with a large opening is provided in between, the strength of the end cover can also be guaranteed, thereby avoiding the risk of breakage caused by rotation of one end of the motor rotor. At the same time, the ventilation slots 23 provided can effectively improve the heat dissipation effect when the motor is working, thereby avoiding the risk of heat generated inside the motor due to excessive speed and being unable to be discharged. In addition, a snap-in slot 26 is provided on the side wall of the reinforcing rib 22, so that the dustproof net 3 can be easily installed to avoid damage caused by external debris entering the motor during operation. The bearing seat 24 provided in the middle and the internal bearing positioning hole 25 can enable the rotor shaft to be inserted into the motor after being connected to the motor, thereby improving the stability of the rotor of the motor when it is working.

[0029] As an improvement of the above technical solution, the reinforcing rib 22 is an arc-shaped structure as a whole and is connected to the middle bearing seat 24. There are multiple groups of reinforcing ribs 22, and the cross-sectional shape and curvature radius of each group are the same. By adopting the arc-shaped reinforcing ribs 22, the overall structure of the end cover can be raised, which makes it more convenient to cover and install the rotor structure inside the motor, increase the internal space, and improve the heat dissipation efficiency. In addition, multiple groups of reinforcing ribs 22 can further enhance the overall strength of the end cover to avoid the end cover from breaking due to excessively high speed of the motor rotor during operation.

[0030] The dustproof net 3 includes a mounting frame 31, and a net plate 32 is arranged inside the mounting frame 31;

[0031] The installation frame 31 is provided so that the dustproof net 3 can be clipped during installation, thereby ensuring that the strength of the overall structure is higher, thereby preventing the dustproof net 3 from breaking during use and entering the motor to damage the motor. At the same time, the mesh plate 32 is clamped inside the installation frame 31, which can be installed more stably and can be replaced more conveniently when the mesh plate 32 is damaged.

[0032] As an improvement of the above technical solution, a non-slip adhesive strip is also provided on the surface of the installation frame 31. The installation frame 31 is fixed by being inserted into the inside of the snap-in groove 26 through the non-slip adhesive strip. It can be pasted and fixed after installation to avoid falling off due to the vibration of the motor during use.

[0033] The present utility model also provides a motor, including the rear end cover structure of the above embodiment. Since the rear end cover structure of the above embodiment is provided, the motor has at least the beneficial effects of the rear end cover structure of the above embodiment, and the details are not repeated. Other structures of the motor, such as the conventional structures of the stator and the rotating shaft, are not described and limited in detail, and are known and easily implemented by those skilled in the art.

[0034] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
