[0032] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0033] This embodiment provides a novel wheel hub motor, including:

[0034] A main body, including a stator structure;

[0035] The mounting bracket 2 is detachably mounted on the stator structure.

[0036] During implementation, the stator structure is first installed in the main body, and then the mounting bracket 2 is installed on the stator structure. Then, the main body is installed on the walking device through the mounting bracket 2. The main body drives the walking device to travel on the road. When the main body needs to be replaced with other walking devices, and the other walking devices have different matching connection structures, the original mounting bracket 2 can be removed and replaced with a mounting bracket 2 that meets the installation conditions of other walking devices. This mounting bracket 2 is installed on the stator structure, and then the mounting bracket 2 is installed on other walking devices. In this way, there is no need to disassemble the internal structure of the main body, thereby avoiding damage to the internal structure of the main body.

[0037] In some embodiments, the stator structure includes a stator seat with an installation cavity and a stator, the stator is installed on the stator seat, and the mounting bracket includes a fixing part and an installation part, the fixing part is detachably installed in the installation cavity; the installation part is arranged at one end of the fixing part, and an installation structure is provided on the installation part.

[0038] During implementation, the fixing part 202 is installed in the installation cavity 101, and the installation part 201 is installed on the walking device through the installation structure. When the installation bracket 2 needs to be replaced, the installation part 201 is first removed from the walking device, and then the fixing part 202 is removed from the installation cavity 101, and then the new installation bracket 2 is installed in the installation cavity 101 and installed on the walking device according to the installation steps.

[0039] In some embodiments, a fixing screw hole 205 is provided on the fixing portion 202, and a through hole corresponding to the fixing screw hole is provided on the stator seat 1. The mounting structure includes a mounting screw hole 205 arranged on the mounting portion 201, and a connecting wire channel is provided on the fixing portion 202 and the mounting portion 201.

[0040] During implementation, the bolt passes through the through hole on the stator seat and is then screwed into the fixing screw hole of the fixing part, so that the fixing part is fixed in the installation cavity. When it needs to be installed on a walking device, the docking component and the installation screw hole on the walking device can be connected by bolts. The wire channel is used for the access of the power-carrying wire, and the power-carrying wire is connected to the internal components of the main body.

[0041] Specifically, the wire channel includes a U-shaped groove 203 and a wire through hole 206. The wire through hole 206 is arranged in the fixing part 202. The wire through hole 206 is located at the center of the fixing part 202. The fixing screw hole 204 and the wire through hole 206 are perpendicular to each other. The U-shaped groove 203 is arranged on the mounting part 201. The U-shaped groove 203 and the wire through hole 206 are vertically connected. The wire first passes through the U-shaped groove 203 and then to the wire through hole 206, and enters the main body from the wire through hole 206. The mounting bracket 2 plays a role in protecting the wire. The wire passes through the U-shaped groove 203 and the wire through hole 206 that are perpendicular to each other. When the mounting part 201 is installed on the walking equipment through the mounting structure, it will not affect the wire passing through the U-shaped groove 203 and the wire through hole 206.

[0042] In some cases, the mounting structure includes a threaded flange disposed on the mounting portion and connected to the walking device via the threaded flange.

[0043] It should be noted that when it is necessary to install on different walking equipment, installation brackets with different installation structures can be used. For example, the docking component of the walking equipment that needs to be replaced may be larger in shape, so the installation bracket that matches the shape of the docking component can be replaced, that is, the predetermined model of the installation bracket can be matched to different walking equipment.

[0044] In some embodiments, the subject comprises:

[0045] The housing 3 is mounted on the stator seat through a rolling bearing;

[0046] The rotor 5 is mounted on the housing 3 and is coaxially arranged with the stator 4 .

[0047] During implementation, the rotor 5 is installed in the shell 3, the stator 4 is installed on the stator seat 1, and the shell 3 is installed on the stator seat 1 through a rolling bearing. When the stator 4 generates a rotating magnetic field, the rotor 5 on the shell 3 senses the rotating magnetic field generated by the stator 4, and the rotor 5 drives the shell 3 to rotate on the stator seat 1. The shell 3 serves as an external rotating structure and also protects the stator 4 and the rotor 5.

[0048] In some embodiments, the housing 3 comprises:

[0049] The rotating shell 301 has a cavity inside and an opening communicating with the cavity is provided on the rotating shell 301;

[0050] The end cover 302 is mounted at the opening of the rotating shell 301 and is provided with a through hole.

[0051] During implementation, the end cover 302 is installed at the opening of the rotating shell 301 . The end cover 302 and the rotating shell 301 are combined to form a shell 3 with an accommodating cavity inside. The stator seat 1 is installed in the cavity of the rotating shell 301 through the through hole on the end cover 302 .

[0052] Specifically, the end cover 302 is provided with a bearing groove at the through hole, and a rolling bearing is provided in the bearing groove. When the stator seat 1 passes through the through hole on the end cover 302 and also passes through the bearing on the end cover 302, the end cover 302 can rotate on the mounting shaft through the rolling bearing, and the rotating shell 301 connected to the end cover 302 can also rotate accordingly.

[0053] In some embodiments, a central shaft 303 is disposed on the rotating shell 301 , and the central shaft 303 is disposed in the installation cavity 101 via a rolling bearing.

The central shaft 303 passes through the rolling bearing in the installation cavity 101 of the stator seat 1, so that the central shaft 303 is rotatably installed in the installation cavity 101. When the rotating shell 301 rotates, the central shaft 303 rotates in the installation cavity 101 through the rolling bearing. Through the rotatable connection of the central shaft 303 in the installation cavity 101 of the stator seat 1, the rotating shell 301 can be fixed on the stator seat 1 and can also rotate relative to the stator seat 1. At the same time, the installation of the central shaft 303 in the stator seat 1 also saves the space occupied by components, thereby reducing the overall space occupied.

[0055] Specifically, one end of the central axis 303 is fixed to the bottom of the rotating shell 301, and the other end of the central axis 303 passes through the rolling bearing in the mounting cavity 101 so that the central axis 303 is set in the mounting cavity 101. There are two rolling bearings in the mounting cavity 101, and two annular step surfaces are set in the central axis 303. Each rolling bearing is correspondingly set on an annular step surface, and the annular step surface is used to limit the position of the bearing.

[0056] In some embodiments, a bearing groove is provided on the rotating shell 301, a rolling bearing is provided in the bearing groove, and the stator seat 1 is fixed in the fixed bearing.

[0057] In some embodiments, the rotor 5 includes a plurality of permanent magnets 501 , which are fixed around the rotating shell 301 .

[0058] During implementation, the permanent magnet 501 is fixed on the rotating shell 301 . When the stator 4 generates a rotating magnetic field, the permanent magnet 501 on the rotating shell 301 senses the rotating magnetic field generated by the stator 4 , and the rotor 5 drives the rotating shell 301 to rotate on the stator base 1 .

[0059] In some embodiments, a limiting bracket 304 is disposed on the rotating shell 301 , and a plurality of slots 305 are disposed on the limiting bracket 304 . Each permanent magnet 501 corresponds to a slot 305 and is locked in the slot 305 .

[0060] During implementation, the limiting bracket 304 is installed in the rotating shell 301, and then each permanent magnet 501 is correspondingly clamped into the clamping slot 305 of the limiting bracket 304. The limiting bracket 304 limits the position of the permanent magnet 501 on the rotating shell 301 to prevent the permanent magnet 501 from shifting on the rotating shell 301.

[0061] Specifically, the limit bracket 304 is a circular structure, and a plurality of clamping strips 306 extend from the limit bracket 304 , and the plurality of clamping strips 306 are equidistantly surrounded on the limit bracket 304 , and there is a clamping slot 305 between every two clamping strips 306 , and the permanent magnet 501 is clamped in the clamping slot 305 formed by the two clamping strips 306 .
