Technical Field

[0001] The utility model relates to the technical field of drive motors, and particularly relates to a brush end cover for a vehicle engine drive motor. Background Art

[0002] In the development of automotive electrification technology, the engine drive motor plays a crucial role. To ensure the long-term efficient operation of the motor, a heat dissipation component is usually installed on the rear end cover of the motor to ensure that the motor maintains an appropriate temperature during operation.

[0003] The long-term use of the drive motor will cause a large amount of dust to be adsorbed on the surface of the protective cover of the heat dissipation component, which may affect the heat dissipation effect. Therefore, it is necessary to clean and maintain the protective cover. When disassembling the protective cover, it is necessary to unscrew the bolts fixed on the rear end cover to disassemble and assemble the protective cover. Therefore, there is a problem that it is not convenient to disassemble and assemble the protective cover. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a brush end cover for a vehicle engine drive motor, which can effectively solve the problems raised in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A brush end cover for a vehicle engine drive motor, comprising a rear end cover, a heat dissipation mechanism and a disassembly and assembly mechanism. The disassembly and assembly mechanism is fixedly connected to the outer surface of the rear end cover, and the heat dissipation mechanism is fixedly connected to the outer surface of the disassembly and assembly mechanism. The disassembly and assembly mechanism includes an installation frame fixedly connected to the outer surface of the rear end cover, and a plug-in block is slidably connected to the inner side surface of the installation frame;

[0007] A docking frame is fixedly connected to the outer surface of the plug-in block, and a card slot is opened on the outer surface of the plug-in block;

[0008] The heat dissipation mechanism includes a protective cover fixedly connected to the outer surface of the docking frame. A rotating cylinder is rotatably connected to the inner side surface of the protective cover, and multiple groups of fan blades are fixedly connected to the outer surface of the rotating cylinder;

[0009] Further, a spring is fixedly connected to the inner wall of the installation frame, the other end of the spring is fixedly connected to a rotating plate, and a rotating shaft is fixedly connected to the outer surface of the rotating plate. The outer surface of the rotating shaft is rotatably connected to the inner wall of the installation frame;

[0010] Further, a pressing rod is fixedly connected to the surface of the rotating plate away from the spring, and a clamping block for cooperating with the plug-in block is fixedly connected to the outer surface of the rotating plate;

[0011] Further, the disassembly and assembly mechanism further includes a magnetic plate adsorbed on the outer surface of the rear end cover, and the outer surface of the magnetic plate is fixedly connected to the outer surface of the protective cover;

[0012] Further, through holes are formed in the outer surface of the protective cover, and a clamping block is fixedly connected to the inner side surface of the rotating cylinder;

[0013] Further, the heat dissipation mechanism further includes a plurality of heat dissipation back plates fixedly connected to the outer surface of the rear end cover, and the outer surface of the heat dissipation back plate does not contact the outer surface of the fan blade;

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. By pressing the pressing rods on both sides of the installation frame, the other end of the rotating shaft drives the clamping block to move towards the outer side surface of the installation frame, so that the clamping block and the plug block are separated, facilitating the release of the limit on the protective cover. Then, by pulling the protective cover, the plug block and the installation frame are separated, thus facilitating the disassembly of the protective cover and facilitating the cleaning of the dust adsorbed on the outer surface of the protective cover. After the cleaning is completed, the plug block is inserted into the installation frame again, and the outer surface of the magnetic plate adsorbs the outer surface of the rear end cover, thus facilitating the quick disassembly and assembly of the protective cover.

[0016] 2. The clamping block facilitates the clamping connection between the rotating cylinder and the output shaft of the rotor. Thus, when the rotor rotates, it drives the rotating cylinder to rotate. The rotation of the rotating cylinder drives a plurality of fan blades to rotate. The fan blades rotate to blow the gas towards the outer surface of the heat dissipation back plate, facilitating the removal of the heat on the outer surface of the heat dissipation back plate. At the same time, the air flow blows out from the through holes, thus facilitating the heat dissipation of the outer surface of the rear end cover and improving the service life of the drive motor.

Specific implementation mode

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0023] As Figure 1 - Figure 4 shown, a brush end cover of a vehicle engine-driven motor includes a rear end cover 1, a heat dissipation mechanism 2 and a disassembly and assembly mechanism 3. The disassembly and assembly mechanism 3 is fixedly connected to the outer surface of the rear end cover 1, and the outer surface of the disassembly and assembly mechanism 3 is fixedly connected with a heat dissipation mechanism 2. The disassembly and assembly mechanism 3 includes an installation frame 301 fixedly connected to the outer surface of the rear end cover 1. The inner side surface of the installation frame 301 is slidably connected with an insertion block 306. The outer surface of the insertion block 306 is fixedly connected with a docking frame 304, and a card slot is opened on the outer surface of the insertion block 306.

[0024] In order to facilitate the disassembly and assembly of the protective cover 205, a spring 308 is fixedly connected to the inner wall of the installation frame 301. The other end of the spring 308 is fixedly connected with a rotating plate 303. The outer surface of the rotating plate 303 is fixedly connected with a rotating shaft 307. The outer surface of the rotating shaft 307 is rotatably connected to the inner wall of the installation frame 301. The spring 308 facilitates the reset of the rotating plate 303. A pressing rod 302 is fixedly connected to the side of the rotating plate 303 away from the spring 308, and a clamping block 309 for cooperating with the insertion block 306 is fixedly connected to the outer surface of the rotating plate 303. The clamping block 309 facilitates the limitation of the insertion block 306, so that the insertion block 306 can be quickly inserted into the installation frame 301. The disassembly and assembly mechanism 3 further includes a magnetic attraction plate 305 adsorbed on the outer surface of the rear end cover 1. The outer surface of the magnetic attraction plate 305 is fixedly connected to the outer surface of the protective cover 205. The magnetic attraction plate 305 facilitates the adsorption of the protective cover 205 on the outer surface of the rear end cover 1, increasing the connection strength between the protective cover 205 and the rear end cover 1.

[0025] It is worth mentioning that by pressing the pressing rods 302 on both sides of the mounting frame 301, the other end of the rotating shaft 307 drives the clamping block 309 to move towards the outer side of the mounting frame 301, so that the clamping block 309 and the plug-in block 306 are separated, facilitating the release of the limit on the protective cover 205. Then, by pulling the protective cover 205, the plug-in block 306 and the mounting frame 301 are separated, thus facilitating the disassembly of the protective cover 205 and facilitating the cleaning of the dust adsorbed on the outer surface of the protective cover 205. After cleaning, the plug-in block 306 is inserted back into the mounting frame 301, and the outer surface of the magnetic attraction plate 305 adsorbs the outer surface of the rear end cover 1, thus facilitating the quick disassembly and assembly of the protective cover 205.

[0026] To dissipate heat from the rear end cover 1, the heat dissipation mechanism 2 includes a protective cover 205 fixedly connected to the outer surface of the docking frame 304. A rotating cylinder 202 is rotatably connected to the inner side of the protective cover 205. A plurality of fan blades 201 are fixedly connected to the outer surface of the rotating cylinder 202. A through hole 204 is formed in the outer surface of the protective cover 205. A clamping block 206 is fixedly connected to the inner side of the rotating cylinder 202. The clamping block 206 facilitates the clamping connection between the rotating cylinder 202 and the output shaft of the rotor. Thus, when the rotor rotates, it drives the rotating cylinder 202 to rotate, facilitating the heat dissipation of the outer surface of the rear end cover 1. The heat dissipation mechanism 2 further includes a plurality of heat dissipation backplates 203 fixedly connected to the outer surface of the rear end cover 1. The outer surface of the heat dissipation backplate 203 does not contact the outer surface of the fan blade 201. The plurality of heat dissipation backplates 203 facilitate increasing the heat dissipation area of the rear end cover 1 and improving the heat dissipation efficiency of the rear end cover 1.

[0027] It is worth mentioning that the clamping block 206 facilitates the clamping connection between the rotating cylinder 202 and the output shaft of the rotor. Thus, when the rotor rotates, it drives the rotating cylinder 202 to rotate. The rotation of the rotating cylinder 202 drives the plurality of fan blades 201 to rotate. The rotation of the fan blades 201 blows the gas towards the outer surface of the heat dissipation backplate 203, facilitating the removal of the heat on the outer surface of the heat dissipation backplate 203. At the same time, the air flow blows out from the through hole 204, thus facilitating the heat dissipation of the outer surface of the rear end cover 1 and improving the service life of the drive motor.

[0028] Working principle: By pressing the pressing rods 302 on both sides of the mounting frame 301, the pressing rods 302 drive the rotating plate 303 to rotate around the rotating shaft 307 as the central axis, and then squeeze the spring 308, so that the other end of the rotating shaft 307 drives the clamping block 309 to move towards the outer side of the mounting frame 301, and then the clamping block 309 and the plug-in block 306 are separated, which is convenient for releasing the limit on the protective cover 205. Then, pull the protective cover 205 to separate the plug-in block 306 from the mounting frame 301, which is convenient for disassembling the protective cover 205 and cleaning the dust adsorbed on the outer surface of the protective cover 205. After cleaning, insert the plug-in block 306 into the mounting frame 301 again, so that the outer surface of the magnetic adsorption plate 305 adsorbs the outer surface of the rear end cover 1, which is convenient for quickly disassembling and assembling the protective cover 205. The rotating cylinder 202 and the output shaft of the rotor can be clamped by the clamping block 206. Then, when the rotor rotates, it drives the rotating cylinder 202 to rotate. The rotation of the rotating cylinder 202 drives multiple groups of fan blades 201 to rotate. The rotation of the fan blades 201 blows the gas towards the outer surface of the heat dissipation back plate 203, which is convenient for taking away the heat on the outer surface of the heat dissipation back plate 203. At the same time, the air flow blows out from the through hole 204, which is convenient for dissipating the heat on the outer surface of the rear end cover 1 and improving the service life of the driving motor.
