[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a skateboard wheel hub motor that facilitates internal cleaning: A skateboard wheel hub motor that facilitates internal cleaning includes an electric trolley 1, a hub motor 3 that is rotatably connected to one end of the electric trolley 1 via a rotating shaft, a tire 4 that is fitted into the outer wall of the hub motor 3, and a cleaning mechanism 2 that is fitted into the side of the tire 4 on one side of the electric trolley 1.

[0022] The cleaning mechanism 2 includes a limiting block 201, a motor cover 202, a positioning plate 203, and bolts 205. The positioning plate 203 is slidably fitted inside one side of the electric flatbed trolley 1. The motor cover 202 is installed on one side of the positioning plate 203 and slidably fitted inside one side of the tire 4, contacting one side of the outer wall of the hub motor 3. The motor cover 202 and the positioning plate 203 are rotatably connected by a shaft. Multiple limiting blocks 201 are provided, and multiple limiting blocks 201 are circumferentially fixed to one side of the outer wall of the hub motor 3 and penetrate into the interior of the motor cover 202. The limiting blocks 201 and the hub motor 3 are integrally formed by heat pressing. The bolt 205 is installed on the outer wall of one side of the positioning plate 203 and extends through the positioning plate 203 into the interior of the electric cart 1. When in use, the hub motor 3 can be started to operate. At this time, the hub motor 3 drives the vehicle hub to rotate through the rotor, and the vehicle hub drives the tire 4 to rotate. At the same time, the electric cart 1 moves the user under the push of the tire 4. When it is necessary to clean the hub motor 3, the hub motor 3 and the tire 4 can be easily disassembled through the cleaning mechanism 2, which is conducive to cleaning and maintenance of the hub motor 3. Then, the above operation is reversed to facilitate the reuse of the electric cart 1.

[0023] The cleaning mechanism 2 also includes a limiting plate 204, a connecting rod 206, a limiting pressure plate 207, and a spring 208. The limiting plate 204 is fixed to one side of the positioning pressure plate 203 and extends into the interior of the electric trolley 1, located at one end of the bolt 205. The limiting plate 204 and the positioning pressure plate 203 are fixedly connected by welding. The connecting rod 206 is fixed to the side of the limiting plate 204 away from the positioning pressure plate 203. The connecting rod 206 and the limiting plate 204 are integrally formed by hot pressing. The limiting pressure plate 207 is fixed to the connecting rod 206. On the side away from the limiting plate 204, the limiting pressure plate 207 and the connecting rod 206 are integrally formed by hot pressing. The spring 208 is set on the outer wall of one side of the limiting pressure plate 207 and is sleeved with the connecting rod 206. By rotating the bolt 205 to remove it, the positioning pressure plate 203 is pulled away from the inside of the electric trolley 1. At the same time, the positioning pressure plate 203 drives the motor cover 202 to detach from the inside of one side of the tire 4 through the rotating shaft. At this time, the motor cover 202 separates from the hub motor 3 and the limiting insert 201. Meanwhile, the limiting plate 204 is positioned on the positioning pressure plate 203. Driven by the movement, the motor cover 202 detaches from the interior of the electric cart 1. At this time, the limiting plate 204, through the connecting rod 206, drives the limiting pressure plate 207 to slide along the inner wall of the electric cart 1. Simultaneously, the limiting pressure plate 207 compresses the spring 208. The spring 208, blocked by the protrusion of the electric cart 1, contracts under the pressure of the limiting pressure plate 207. When the motor cover 202 is completely detached from the interior of the tire 4 and located on one side of the electric cart 1, the positioning pressure plate 203 is pulled to rotate around the connecting rod 206 as the axis. Simultaneously, the motor cover 202 is positioned... Driven by the pressure plate 203, it flips to the top of one side of the electric trolley 1, and then the positioning pressure plate 203 is released. At this time, the spring 208 pushes the limiting pressure plate 207 to reset by rebound. At the same time, the limiting pressure plate 207 pulls the limiting clamping plate 204 to reset through the connecting rod 206. At this time, the positioning pressure plate 203 is tightly attached to the outer wall of one side of the electric trolley 1 under the action of the limiting clamping plate 204, so as to limit and fix the motor cover 202 and the positioning pressure plate 203, so as to facilitate the easy disassembly of the hub motor 3 and the tire 4, and facilitate the cleaning and maintenance of the hub motor 3.

[0024] Among them, the outer wall of the limiting plug 201 away from the hub motor 3 is conical. The motor cover 202 is provided with a mating slot that matches its outer wall at the position where it connects with the multiple limiting plugs 201. Through the mutual cooperation between the conical outer wall and the mating slot, the motor cover 202 can contact the outer wall of the hub motor 3 and block and limit the limiting plug 201 when it is sleeved.

[0025] Among them, the outer wall of the hub motor 3 and the motor cover 202 fits into the inner wall of the tire 4. The electric cart 1, the positioning plate 203 and the bolt 205 are connected by a threaded groove that matches their external thread. The bolt 205 can pass through the positioning plate 203 and rotate into the interior of the electric cart 1, thereby limiting and fixing the positioning plate 203.

[0026] The electric trolley 1 has a sliding slot at the junction with the positioning plate 203 and the limiting plate 204. The electric trolley 1 has a rotating groove at the junction with the connecting rod 206 and the limiting plate 207. The electric trolley 1 has a protrusion on the side of the spring 208 away from the limiting plate 207 that matches the outer wall of the connecting rod 206. Through the cooperation of the limiting slot and the rotating groove, the limiting plate 204 can be moved by the connecting rod 206 to pull the limiting plate 207 under the drive of the positioning plate 203. At the same time, the limiting plate 207 squeezes the spring 208. At this time, the spring 208 is blocked by the protrusion of the electric trolley 1 and is compressed by the limiting plate 207.

[0027] Working Principle: During use, the hub motor 3 is activated to rotate the tire 4. Simultaneously, the electric trolley 1 moves the user under the push of the tire 4. When cleaning the hub motor 3 is required, the bolt 205 is rotated off, and then the positioning plate 203 is pulled away from the electric trolley 1. Simultaneously, the positioning plate 203, via a rotating shaft, causes the motor cover 202 to detach from one side of the tire 4. At this point, the motor cover 202 separates from the hub motor 3 and the limiting block 201. Simultaneously, the limiting plate 204, driven by the positioning plate 203, detaches from the electric trolley 1. The limiting plate 204, via the connecting rod 206, causes the limiting plate 207 to slide along the inner wall of the electric trolley 1. Simultaneously, the limiting plate 207 compresses the spring 208. At this time, the spring 208, blocked by the protruding block of the electric trolley 1, is pushed away by the limiting plate 207. When the motor cover 202 is completely detached from the inside of the tire 4 and located on one side of the electric trolley 1, the positioning pressure plate 203 is pulled to rotate around the connecting rod 206. At the same time, the motor cover 202 is flipped to the upper side of the electric trolley 1 under the action of the positioning pressure plate 203. Then the positioning pressure plate 203 is released. At this time, the spring 208 pushes the limiting pressure plate 207 to reset through rebound. At the same time, the limiting pressure plate 207 pulls the limiting clamping plate 204 to reset through the connecting rod 206. At this time, the positioning pressure plate 203 is pressed against the outer wall of one side of the electric trolley 1 under the action of the limiting clamping plate 204, thereby limiting and fixing the motor cover 202 and the positioning pressure plate 203, so as to facilitate the easy disassembly of the hub motor 3 and the tire 4, and to facilitate the cleaning and maintenance of the hub motor 3. Then the above operation is reversed to facilitate the reuse of the electric trolley 1.
