Hub motors are motors designed to integrate the vehicle's power system, transmission system, and brake system. Their working principle is a permanent magnet synchronous motor. Wheel-side motors and hub motors refer to motors installed in different positions on the vehicle.

[0003] Since industrial hub motors generate heat when in use, and hub motors generally only conduct heat through their own housing, the heat dissipation effect is poor, which can easily affect the service life of the hub motor; since the hub motor is installed inside the wheel, it is close to the ground. If there are water stains on the ground, it is easy to splash onto the surface of the hub motor. Therefore, the cover of the hub motor is generally sealed to the housing through a sealing ring, but the sealing ring is prone to aging after a long time, which can easily affect the sealing and waterproof effect of the hub motor when in use; the cover of the industrial hub motor is generally fixed to the housing by at least four screws. If maintenance is required, the disassembly and assembly of the cover is cumbersome, which reduces the convenience of hub motor maintenance. Utility Model Content

[0014] Preferably, an airbag is provided on one side of the sealing ring, the airbag is adhered to the inner wall of the groove, and the surface of the airbag is tightly fitted with the surface of the insertion frame.

At the same time, under the action of the heat dissipation frame 2011, the temperature-sensitive phase-change liquid 2012 can be cooled to achieve the efficient heat dissipation function of the hub motor.

[0027] Furthermore, if Figure 3As shown, the hub motor body 1 and the cover plate 102 are detachably connected through the maintenance mechanism 3, and the maintenance mechanism 3 is composed of an maintenance component 301 and an outer screw ring 302. The outer screw ring 302 is fixed on the surface of the hub motor body 1, and the hub motor body 1 and the cover plate 102 are detachably connected through the maintenance component 301. The interior of the maintenance component 301 includes an inner screw ring 3011, a fastening bolt 3012 and a turning handle 3013.

[0028] When in use, the cover plate 102 is put onto one end of the rotating shaft 101, so that the inner screw ring 3011 is inserted into the inner side of the outer screw ring 302, and then the turning handle 3013 is rotated to make the turning handle 3013 drive the inner screw ring 3011 to rotate, and the cover plate 102 and the hub motor body 1 are quickly fixed under the thread cooperation of the inner screw ring 3011 and the outer screw ring 302, and then the fastening bolt 3012 is rotated to fix the turning handle 3013 and the hub motor body 1 to prevent the inner screw ring 3011 from loosening, so as to realize the function of facilitating the disassembly and assembly of the cover plate 102 of the hub motor.

[0029] Furthermore, if Figure 4 As shown, a high-efficiency waterproof mechanism 4 is arranged between the hub motor body 1 and the cover plate 102, and the interior of the high-efficiency waterproof mechanism 4 includes a waterproof component 401 and an insertion frame 402. The insertion frame 402 is fixed at the edge of the cover plate 102, and the side structure of the insertion frame 402 is a conical structure. A waterproof component 401 is arranged on the outside of the insertion frame 402, and the waterproof component 401 consists of an airbag 4011, a sealing ring 4012 and a groove 4013. A groove 4013 is opened on one side of the surface of the hub motor body 1, and the groove 4013 and the insertion frame 402 are plugged into each other. A sealing ring 4012 is adhered to the inner wall of the groove 4013, and the surface of the sealing ring 4012 is tightly fitted with the surface of the insertion frame 402. An airbag 4011 is arranged on one side of the sealing ring 4012, and the airbag 4011 is adhered to the inner wall of the groove 4013, and the surface of the airbag 4011 is tightly fitted with the surface of the insertion frame 402.

[0030] During use, when the cover plate 102 covers the surface of the hub motor body 1, the insertion frame 402 is inserted into the groove 4013. At this time, the sealing ring 4012 is tightly attached to the insertion frame 402, and the insertion frame 402 and the groove 4013 are sealed. At the same time, since the insertion frame 402 is a conical structure, the middle part of the insertion frame 402 squeezes the airbag 4011, so that the two sides of the airbag 4011 are tightly attached to the two sides of the insertion frame 402, and the insertion frame 402 and the groove 4013 are sealed again to achieve the efficient sealing and waterproof function of the hub motor.

[0031] Working principle: When in use, first put the cover plate 102 onto one end of the rotating shaft 101, insert the inner screw ring 3011 into the inner side of the outer screw ring 302, then rotate the turning handle 3013, so that the turning handle 3013 drives the inner screw ring 3011 to rotate, and quickly fix the cover plate 102 to the hub motor body 1 under the thread cooperation of the inner screw ring 3011 and the outer screw ring 302, and then rotate the fastening bolt 3012 to fix the turning handle 3013 to the hub motor body 1 to prevent the inner screw ring 3011 from loosening, so as to realize the function of facilitating the disassembly and assembly of the cover plate 102 of the hub motor, thereby improving the convenience of overhauling the hub motor.

[0032] When the cover plate 102 covers the surface of the hub motor body 1, the insertion frame 402 is inserted into the groove 4013. At this time, the sealing ring 4012 is in close contact with the insertion frame 402, and the insertion frame 402 and the groove 4013 are sealed. At the same time, since the insertion frame 402 is a conical structure, the middle part of the insertion frame 402 squeezes the airbag 4011, so that the two sides of the airbag 4011 are in close contact with the two sides of the insertion frame 402, and the insertion frame 402 and the groove 4013 are sealed again to achieve the efficient sealing and waterproof function of the hub motor, thereby improving the sealing and waterproof effect when the hub motor is in use.

[0033] Before use, the temperature-sensitive phase-change liquid 2012 is injected into the heat dissipation frame 2011 through the threaded liquid guide tube 2014, and then the threaded cover 2013 is covered on the surface of the threaded liquid guide tube 2014, and then the threaded cover 2013 is tightened to block the threaded liquid guide tube 2014. The heat generated by the hub motor when working is discharged through the heat dissipation fins 202. At this time, the temperature-sensitive phase-change liquid 2012 near the over-temperature part of the hub motor body 1 will quickly vaporize and absorb heat, and the over-temperature part of the hub motor body 1 will be cooled. Cooling, at the same time, the pressure of the temperature-sensitive phase-change liquid 2012 at other lower temperature places is relatively small, and the temperature-sensitive phase-change liquid 2012 will flow to other lower temperature places after being vaporized, and condense and release heat, and become liquid again. At the same time, under the action of the heat dissipation frame 2011, the temperature-sensitive phase-change liquid 2012 can be cooled to achieve the efficient heat dissipation function of the hub motor, so that the hub motor is not easily damaged due to excessive temperature, thereby extending the service life of the hub motor and finally completing the use of the hub motor.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
