The sealing piece is used to cooperate with the carbon brush to clamp the first spring, and the first spring is used to connect the internal circuit installed on the inner wall of the end cover body through a first wire.

[0003] Although the motor end cap for ABS, ESC, ESP and the motor containing the same can install the internal circuit in the end cap body and then connect the internal circuit with the inductor and carbon brush, etc., the motor end cap for ABS, ESC, ESP and the motor containing the same still have the following disadvantages: since the internal circuit needs to be pre-buried in the mold when the end cap body is manufactured, although the space in the end cap is saved, the internal circuit is built into the end cap body, which makes the production steps of the end cap body cumbersome and reduces the production efficiency. At the same time, after the internal circuit is built into the end cap body, only a small part of it is leaked for welding, which is easy to cause cold welding. At the same time, it is not convenient to detect where the circuit is broken after the internal circuit is built into the end cap body. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0020] like Figures 1 to 3 As shown, the utility model discloses an automobile air suspension motor end cover structure, comprising: an end cover body 1, a brush box 2, a welding foot 3, a carbon brush 4 and an inductor 5; a first placement position and a second placement position are provided on the end cover body 1, the first placement position is used to install the inductor 5, the second placement position is used to install the brush box 2, and the first placement position is located next to the second placement position; the brush box 2 extends to form a welding foot 3, the brush box 2 and the welding foot 3 are both made of conductive material, the welding foot 3 is electrically connected to the inductor 5, the welding foot 3 is electrically connected to the carbon brush 4 through an intermediate connector 6, the carbon brush 4 is installed in the brush box 2, and the carbon brush 4 can move in the radial direction of the end cover body 1 relative to the brush box 2.

[0021] A welding pin 3 for connecting the inductor 5 is arranged on one side of the brush box 2 close to the first placement position, and another welding pin 3 for connecting the intermediate connector 6 is arranged on the side of the brush box 2 away from the first placement position. Two welding pins 3 are arranged on both sides of the brush box 2, one welding pin 3 is convenient for connecting the inductor 5, and the other welding pin 3 is convenient for connecting the intermediate connector 6, and the intermediate connector 6 does not pass through the inductor 5, so as to avoid the electromagnetic field generated around the intermediate connector 6 from affecting the inductor 5, thereby realizing the separation of the inductor 5 and the intermediate connector 6.

[0022] The intermediate connecting member 6 is a brush braid wire. The brush braid wire is made of soft material and will not hinder the movement of the carbon brush 4, making the movement of the carbon brush 4 smoother.

[0023] A positioning assembly 7 is provided on the end cap body 1, and the positioning assembly 7 is used to position the middle of the intermediate connector 6. The positioning assembly 7 positions the middle of the intermediate connector 6, so that the intermediate connector 6 will not move at will, and the intermediate connector 6 is prevented from sticking to other electrical components and affecting the operation of other electrical components.

[0024] The positioning assembly 7 includes: a surrounding column 71, a first blocking block 72, and a second blocking block 73. The end cover body 1 protrudes to form the surrounding column 71, the first blocking block 72, and the second blocking block 73. The first blocking block 72 and the second blocking block 73 are respectively located on both sides of the surrounding column 71. The surrounding column 71 is used to surround the middle part of the intermediate connector 6. The gap between the surrounding column 71 and the first blocking block 72 is used for the intermediate connector 6 to pass through. The gap between the surrounding column 71 and the second blocking block 73 is used for the intermediate connector 6 to pass through. The surrounding column 71 is used to surround the middle part of the intermediate connector 6. The intermediate connector 6 is inserted between the surrounding column 71 and the first blocking block 72. The intermediate connector 6 is also inserted between the surrounding column 71 and the second blocking block 73. After being inserted, the intermediate connector 6 is restricted from disengaging by friction, thereby realizing the positioning of the middle part of the intermediate connector 6.

[0025] The bottom of the brush box 2 extends to form a box hook 20, which passes through the end cover body 1 and hooks the end cover body 1. The box hook 20 and the brush box 2 are formed integrally during manufacturing. During installation, the box hook 20 passes through the end cover body 1, and then the box hook 20 is riveted to make the box hook 20 a curved structure, so that the box hook 20 hooks the end cover body 1, and then restricts the entire brush box 2 from being separated from the end cover body 1. The installation steps are simple, and the installation efficiency is improved.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
