Description
Technical Field
The utility model relates to the technical field of motors, in particular to a rear bracket component of a four-pole motor.
Background
The shell, the front cover and the rear cover of the common motor are arranged compactly, and the heat dissipation effect is poor. Therefore, for applications requiring less water and dust resistance, a new structure has been proposed to improve the heat dissipation effect. For example, chinese patent with publication number CN 213906440U proposes a front bracket of a four-pole motor, which improves the heat dissipation effect of the motor compared with that of a common motor, but does not improve the rear bracket, and still needs to be further improved. In view of the defects in the prior art, the utility model provides a rear bracket of a four-pole motor, which can further improve the heat dissipation effect of the four-pole motor.
It can be seen that there is a need for improvements and improvements in the art.
Disclosure of Invention
In view of the above-mentioned shortcomings of the prior art, the present utility model aims to provide a rear bracket assembly of a four-pole motor, which aims to solve the technical problem that the heat dissipation effect of the four-pole motor is to be improved in the prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a rear bracket assembly of a four-pole motor comprises a rear bracket, wherein the rear bracket comprises a body and four mounting lugs, each mounting lug comprises a cross arm, a vertical arm and a mounting arm, and each mounting arm is provided with a connecting hole; the bearing chamber is arranged on the body, the base plate and the carbon brush plate are arranged on the inner side of the body, and four carbon brush boxes are uniformly arranged on the inner side of the carbon brush plate.
Furthermore, in the four-pole motor rear bracket component, the four mounting lugs have the same specification and are uniformly distributed on the body.
Further, in the four-pole motor rear bracket assembly, the body and the four mounting lugs are integrally formed.
Further, in the four-pole motor rear bracket assembly, the included angle between each vertical arm and the corresponding cross arm is 90-110 degrees.
Furthermore, in the four-pole motor rear bracket component, the backing plate and the carbon brush plate are both insulating plates.
Further, in the four-pole motor rear bracket assembly, the four carbon brush plates correspond to the four mounting lugs one by one.
The beneficial effects are that: compared with the prior art, the rear bracket of the four-pole motor provided by the utility model can be conveniently connected with the stator of the four-pole motor by arranging the body and the four mounting lugs, so that the compact structure of the four-pole motor is ensured, and the heat dissipation effect of the four-pole motor is further improved.

Fig. 1 is a perspective view of a rear bracket assembly of a four-pole motor provided by the utility model.
Fig. 2 is an exploded view of the rear bracket assembly of the four-pole motor provided by the utility model.
Fig. 3 is a schematic view of an application state of the rear bracket assembly of the four-pole motor.
Description of the embodiments
The utility model provides a rear bracket of a four-pole motor, which is further described in detail below for the purpose, technical scheme and effect of the utility model to be clearer and more definite. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1 to 3, the present utility model provides a rear bracket assembly of a four-pole motor. The drawings are only for the purpose of illustrating the structural principles and are not to scale with respect to actual products. The "cross arm" and "vertical arm" are described herein for ease of illustration only and are not intended to limit the specific orientation of the product.
A rear bracket assembly of a four-pole motor comprises a rear bracket, wherein the rear bracket comprises a body 1 and four mounting lugs 2, each mounting lug comprises a cross arm 21, a vertical arm 22 and a mounting arm 23, and each mounting arm is provided with a connecting hole 20; the bearing chamber 11 is arranged on the body, the base plate and the carbon brush plate 34 are arranged on the inner side of the body, and four carbon brush boxes 5 are uniformly arranged on the inner side of the carbon brush plate. The body, the backing plate and the carbon brush plate are connected through bolts 19.
Preferably, the four mounting ears are identical in size and are evenly distributed on the body. This arrangement makes the rear bracket easier to install.
Further, the body and the four mounting ears are integrally formed. Specifically, the body and the mounting lug can be integrally formed in a stamping mode, and the body and the mounting lug can be conveniently machined.
Preferably, the included angle between each vertical arm and the corresponding cross arm is 90-110 degrees. The included angle between the vertical arm and the corresponding cross arm is not smaller than 90 degrees, so that interference between the rear bracket and the stator during actual installation can be avoided; the included angle between the vertical arm and the corresponding cross arm is not more than 110 degrees, so that the mounting arm can be prevented from being excessively far away from the stator, and the rear bracket is compact in structure.
Preferably, the backing plate and the carbon brush plate are both insulating plates.
Preferably, the positions of the four carbon brush plates and the four mounting lugs are in one-to-one correspondence, and the carbon brush plates have enough mounting positions by the arrangement, so that the diameter of the body is prevented from being too large.
As appears from fig. 3, in actual installation, the connection holes of each installation arm pass through the bolts 91 and are connected with the stator 9 of the corresponding four-pole motor, respectively. The four-pole motor has compact structure on the whole and improves the heat dissipation effect.
It will be understood that equivalents and modifications will occur to those skilled in the art based on the present utility model and its spirit, and all such modifications and substitutions are intended to be included within the scope of the present utility model.
