Description

Technical Field

[0002] A carbon brush is a device used in electric motors or generators. It is made of carbon graphite material and is usually installed on the commutator or slip ring of the motor. As a sliding contact that conducts current, it can change the direction of the current, enabling the motor to operate normally. The role of the carbon brush in the motor is very important. It can introduce the direct current from the power supply into the rotor through the commutator or slip ring, thereby changing the conductive coil of the rotor, changing the rotor magnetic pole, and thus changing the direction of the motor's movement. At the same time, the carbon brush also has good conductivity and high temperature resistance, and can withstand the mechanical shock and high temperature environment of the motor.

[0003] The problem with existing technology is that when the motor is working, the heat of the motor is transferred to the surface of the carbon brush, which accelerates the wear of the carbon brush. At the same time, the carbon brush needs to be cleaned regularly. However, the existing method of fixing the carbon brush with screws requires the use of corresponding tools for installation and disassembly, which is relatively troublesome. Utility Model Content

[0028] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0029] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] like Figures 1 to 4As shown, the present invention provides a motor carbon brush protection device, including a first motor 1, a mounting part 2 and a carbon brush 3. The mounting part 2 is located on the front side of the first motor 1, and the carbon brush 3 is located inside the mounting part 2 and extends to the top and bottom of the mounting part 2. A heat dissipation mechanism 4 is provided on the front side of the mounting part 2.

[0031] The heat dissipation mechanism 4 includes a vent 401, a fan 402, and a second motor 403. The vent 401 is located on the front side of the mounting component 2. The fan 402 is fixedly connected to the front side of the mounting component 2. The second motor 403 is located on the front side of the fan 402. The fan 402 is fixedly connected to the transmission end of the second motor 403.

[0032] Clamping mechanism 5 is disposed on the surface of carbon brush 3;

[0033] Telescopic mechanism 6 is located on top of clamping mechanism 5.

[0034] refer to Figure 4 The clamping mechanism 5 includes a transmission box 501, two clamping plates 502 and two first springs 503. The transmission box 501 is located on the top of the carbon brush 3, the clamping plates 502 are located on both sides of the carbon brush 3 and extend into the interior of the transmission box 501, and the first springs 503 are fixedly connected to the opposite side of the clamping plates 502.

[0035] The above solution is adopted: by setting up a clamping mechanism 5, the carbon brush 3 can be clamped and positioned.

[0036] refer to Figure 3 The telescopic mechanism 6 includes a fixed plate 601, a telescopic rod 602, and a telescopic groove 603. The fixed plate 601 is fixedly connected to the top of the front side of the mounting component 2, the telescopic rod 602 is fixedly connected to the top of the transmission box 501, the telescopic groove 603 is opened inside the fixed plate 601 and extends to the top and bottom of the fixed plate 601, and the telescopic rod 602 is slidably connected to the inside of the telescopic groove 603.

[0037] The above solution is adopted: by setting the telescopic mechanism 6, the transmission box 501 can be moved through the telescopic mechanism 6, so as to avoid affecting the installation of carbon brush 3.

[0038] refer to Figure 4 Each of the clamping plates 502 has a handle 7 fixedly connected to the opposite side and extends to both sides of the transmission box 501. Both sides of the transmission box 501 have openings 8 that cooperate with the handle 7.

[0039] The above solution is adopted: by setting handle 7 and opening 8, handle 7 can facilitate manual movement of clamping plate 502, and opening 8 can limit the movement of handle 7.

[0040] refer to Figure 3 The bottom of the fixing plate 601 is fixedly connected to the second spring 9, which is located on the surface of the telescopic rod 602.

[0041] The above solution is adopted: by setting a second spring 9, the transmission box 501 and the clamped carbon brush 3 can be transmitted through the second spring 9, so that the carbon brush 3 is kept in contact with the surface of the first motor 1.

[0042] refer to Figure 4 Both sides of the bottom of the transmission box 501 are provided with movable grooves 10 that cooperate with the clamping plate 502 and are connected to the opening 8. The first spring 503 is fixedly connected to the inner wall of the movable groove 10.

[0043] By adopting the above solution, by setting the movable groove 10, the clamping plate 502 can be moved inside the transmission box 501.

[0044] refer to Figure 4 Limiting rods 11 are fixedly connected to the top of opposite sides of the clamping plate 502, and the inner wall of the moving groove 10 is provided with a limiting groove 12 that is slidably connected to the limiting rods 11.

[0045] The above solution is adopted: by setting the limiting rod 11 and the limiting groove 12, the clamping plate 502 can be limited to move by the cooperation of the limiting rod 11 and the limiting groove 12, so that the clamping plate 502 can only move to the left and right.

[0046] The working principle of this utility model:

[0047] When installing carbon brush 3, the user first manually moves handle 7 to the opposite side, causing the clamping plate 502 to move to the opposite side and simultaneously retracting the first spring 503. Then, the user manually moves the transmission box 501 upward, causing the second spring 9 to retract. The carbon brush 3 is then placed inside the mounting part 2. The transmission box 501 is then moved downward, making it fit against the carbon brush 3. The user then releases handle 7, and the automatic extension of the first spring 503 causes the clamping plate 502 to move to the corresponding side, clamping the carbon brush 3. The installation is then complete. The second motor 403 then operates, driving the fan 402 to work. The fan 402 dissipates heat from the carbon brush 3, preventing it from being exposed to high temperatures for extended periods and increasing wear.

[0048] In summary, this motor carbon brush protection device, through the arrangement of a heat dissipation mechanism 4, a clamping mechanism 5, and a telescopic mechanism 6, achieves the following: the heat dissipation mechanism 4 dissipates heat from the carbon brush 3; the clamping mechanism 5 clamps and positions the carbon brush 3; and the telescopic mechanism 6 allows the transmission box 501 to move, preventing interference with the installation of the carbon brush 3. It offers the advantages of heat dissipation for the carbon brush 3 and easy disassembly and cleaning. This solves the problem that in existing motors, heat is transferred to the surface of the carbon brush during operation, accelerating carbon brush wear and requiring regular cleaning. Furthermore, existing methods use screws to fix the carbon brush, requiring tools for installation and disassembly, making installation and disassembly cumbersome.
