In this embodiment, the mounting platform 31 on the base 3 is fixedly installed in cooperation with the connecting component 4, and the connecting component 4 can be a joint or fuselage, a frame or other structure of a mobile device, an inner diameter connecting portion 22 is provided on the end cover 2, and a gap is formed between the inner diameter connecting portion 22 and the mounting platform 31, and a material stopper 23 is provided on the gap to prevent debris from entering the motor when the hub motor is driving, and is suitable for various smart homes, such as floor scrubbers, cleaning robots and other mobile robots. It protects the internal structure of the motor and extends its service life.
[0027] In the above embodiment, the inner diameter connecting portion 22 is provided with a retaining ring 221 protruding toward the connecting component 4, and the connecting component 4 is provided with a first matching groove 421, and one end of the retaining ring 221 vertically extends into the first matching groove 421; the retaining ring 221 is vertically extended into the first matching groove 421 to cooperate with each other to form a curved maze channel to prevent external debris from entering the interior of the motor.
[0028] The anti-winding design of the above embodiment prevents hair or other objects from winding around the motor housing 1 or entering the motor by rotatably connecting the base 3 to the motor housing 1 and providing an outer diameter connecting portion 21 on the end cover 2 to connect to the motor housing 1.
[0029] In the above embodiment, a mounting platform 31 is provided on the base 3, and there is a gap between the mounting platform 31 and the inner diameter connection part 22. At the same time, a material stopper 23 is provided on the inner diameter connection part 22 toward the mounting platform 31. This design can ensure that hair or other objects will not enter the inside of the motor through the gap during the operation of the motor. The material stopper 23 plays a role in preventing entangled objects from entering the inside of the motor, effectively protecting the safe operation of the internal components of the motor.
[0030] A yoke portion 11 is provided on the outer periphery of the motor housing 1, a connecting platform 12 is provided on the top of the yoke portion 11, a connecting ring 211 is provided on the outer diameter connecting portion 21, and the inner diameter of the connecting platform 12 is fitted with the outer diameter of the connecting ring 211. In this embodiment, by providing the yoke portion 11 and the connecting platform 12 on the outer periphery of the motor housing 1, and providing the connecting ring 211 on the outer diameter connecting portion 21, the effect of preventing windings from entering the interior of the motor is achieved. The fitting design of the connecting platform 12 and the connecting ring 211 can prevent windings from entering the interior of the motor along the surface of the housing, and effectively protect the safe operation of the internal components of the motor. The arrangement of the yoke portion 11 provides additional structural strength and stability on the motor housing 1. This design can increase the rigidity of the housing, reduce the deformation and vibration of the housing, and improve the overall stability and reliability of the motor. By optimizing the design of the yoke portion 11 and the connecting platform 12, the unevenness and friction resistance on the surface of the motor housing 1 are reduced, which helps to improve the operating efficiency and power output of the motor.
[0031] After the connecting platform 12 is connected to the connecting ring 211, a placement cavity 121 is formed in the motor housing 1, and the base 3 is provided with a blocking step 32, a blocking groove 33 formed between the blocking step 32 and the inner diameter connecting part 22, and one end of the material blocking part 23 protrudes toward the blocking groove 33. In this embodiment, the placement cavity 121 formed after the connecting platform 12 is connected to the connecting ring 211 can be used to install the stator and mover components of the motor. By placing these components in the placement cavity 121, the stable operation of the motor is ensured. The blocking groove 33 formed between the blocking step 32 and the inner diameter connecting part 22 can be used to block external debris from entering the motor, preventing the winding from interfering with and damaging the operation of the motor. One end of the material blocking part 23 protrudes toward the blocking groove 33, which can further prevent the components in the placement cavity 121 from entering the blocking groove 33. The raised design of the material blocking part 23 increases the physical barrier of the blocking groove 33, improves the anti-winding effect, and ensures the safe operation of the motor.
[0032] A blocking seal 34 is provided in the blocking groove 33, and the blocking seal 34 seals the blocking groove 33, and one end of the material stopper 23 abuts against the blocking seal 34. In this embodiment, by providing the blocking seal 34 in the blocking groove 33, effective sealing of the blocking groove 33 can be achieved. The installation of the blocking seal 34 can prevent the penetration of external media, liquids or gases into the blocking groove 33, thereby preventing the winding from entering the interior of the base 3 or leaking out. The design and material selection of the blocking seal 34 can ensure that it fits tightly with the blocking groove 33, thereby improving the overall sealing performance. This sealing design can effectively prevent the winding from entering the interior of the base 3 along the edge of the blocking groove 33, ensuring the normal operation and reliability of the motor. One end of the material stopper 23 abuts against the blocking seal 34, which can increase the tightness of the seal. This design ensures physical contact between the material stopper 23 and the blocking seal 34, further preventing the winding from entering the interior of the base 3 through the material stopper 23.
[0033] The stopper 23 is arranged at the inner diameter of the retaining ring 221. Specifically, the end cover 2 is provided with a sink 222 on the outer periphery of the retaining ring 221, and the end cover 2 is provided with a boss 223 on the outer side of the sink 222. The connecting component 4 includes a fixed connecting portion 41 and a matching step 42, wherein the fixed connecting portion 41 is connected to the mounting platform 31, and the matching step 42 is arranged on one side of the fixed connecting portion 41, and the matching step 42 is used to match the retaining ring 221. The matching step 42 includes a matching boss 422 and a second matching groove 423 connected in sequence, wherein the matching boss 422 extends toward the sink 222, and the second matching groove 423 is used to match the boss 422 to form a labyrinth-shaped through groove. In this embodiment, the convex arrangement of the retaining ring 221 and the arrangement of the stopper 23 effectively prevent the winding from entering the connecting component 4. The retaining ring 221 acts as a physical barrier to block the entry of the winding, while the stopper 23 limits the position of the winding to ensure that it does not interfere with the connecting component 4. The arrangement of the sink 222 and the boss 223 on the end cover 2 increases the barrier against winding. As a part of the material retaining portion 23, the sink 222 further limits the range of winding. The boss 223 guides the winding flow to the through groove, forming a maze structure, which enhances the anti-winding effect. The design of the matching step 42 ensures the stability of the connecting component 4. The matching relationship between the first matching groove 421, the matching boss 422 and the second matching groove 423 ensures the tight connection between the connecting component 4 and the retaining ring 221, and provides reliable support and fixation.
[0034] The base 3 is provided with a shaft assembly 35, and the base 3 is rotatably connected to the motor housing 1 through the shaft assembly 35. In this embodiment, the shaft assembly 35 is composed of a rotating shaft and a bearing, and the bearing is fixedly connected to the motor housing 1, and the rotating shaft can rotate under the action of the bearing.
[0035] A mobile device includes an anti-winding structure of a hub motor. The device is particularly suitable for use in robots in the fields of smart homes and the like, and is used as a mobile component to prevent external substances from winding around or entering the motor.
