It can be understood that the hub 1311 is provided with an insertion hole 1311a in the axial direction of the rim 1313, and the insertion hole 1311a is used for mounting the fixing member so as to connect the hub 1311 and the rotating member. It can be understood that when the wheel 131 is connected to the frame 11 and the wheel 131 is righted, the width direction of the wheel 131 is parallel to the width direction of the frame 11, i.e. the width direction of the wheel 131 is parallel to the left-right direction.

[0033] In some embodiments, the rim 1313 is annular, the axial direction of the rim 1313 is parallel to the width direction of the wheel 131, and the radial direction of the rim 1313 is perpendicular to the width direction of the wheel 131.

[0034] With reference to Figure 1 and Figure 4 In some embodiments, the wheel 131 further comprises a tire 1314 arranged on the rim 1313. The tire 1314 is used to form elastic contact between the rim 1313 and the road surface, and is used to play the effects of shock absorption and increased friction.

[0035] The wheel 131 further comprises a decorative assembly 200 arranged on the side of the wheel spoke 1312 away from the frame 11 along the width direction of the wheel 131, so that the decorative assembly 200 covers the wheel spoke 1312 and the wheel hub 1311 to play a protective effect on the wheel spoke 1312 and the wheel hub 1311. In other embodiments, the decorative assembly 200 can also cover the rim 1313 to play a protective effect on the rim 1313.

[0036] With reference to Figure 4 and Figure 5 The decorative assembly 200 comprises a decorative cover 21, a clamping member 22, and a plurality of clamping members 23. The plurality of clamping members 23 are arranged around the width direction of the wheel 131, the clamping members 23 are fixedly connected to the decorative cover 21, and the plurality of clamping members 23 are clamped to the wheel spoke 1312.

[0037] Exemplarily, the decorative cover 21 is substantially disc-shaped, and the decorative cover 21 is arranged in a fully enclosed manner. It can be understood that the decorative cover 21 is a structure without holes on the surface and the decorative cover 21 completely covers the wheel spoke 1312 and the wheel hub 1311.

[0038] In some embodiments, the plurality of clamping members 23 are uniformly distributed in sequence along the circumferential direction, and the distribution path of the plurality of clamping members 23 can be defined as a distribution circle 201. Optionally, the distribution circle 201 is concentric with the outer edge of the decorative cover 21.

[0039] The clamping member 22 is sleeved on the outer periphery of the plurality of clamping members 23, and the clamping member 22 has a switchable clamping state and a loose state. When the clamping member 22 is switched from the loose state to the clamping state, the clamping member 22 clamps the clamping members 23 and causes the clamping members 23 to elastically bend and deform towards the center line direction of the rim 1313, so that the clamping members 23 are separated from the wheel spoke 1312.

[0040] With reference to Figures 4 to 6In some embodiments, the spoke 1312 is provided with a clamping hole 1312a along the width direction of the wheel 131, the clamping member 23 comprises a clamping rod 231 and a clamping protrusion 232, the clamping protrusion 232 is arranged on the clamping rod 231, the clamping rod 231 is arranged on the decorative cover 21 and is inserted into the clamping hole 1312a, and the clamping protrusion 232 and the decorative cover 21 abut the side walls on opposite sides of the spoke 1312, respectively, wherein, along the radial direction of the distribution circle 201, the clamping protrusion 232 is located on the side of the corresponding clamping rod 231 away from the center of the distribution circle 201, and the clamping protrusion 232 abuts the side wall of the spoke 1312 on the side of the corresponding clamping hole 1312a away from the center of the distribution circle 201. In other embodiments, the clamping protrusion 232 abuts the side wall of the spoke 1312 on the side away from the decorative cover 21 along the width direction of the wheel 131, and the decorative cover 21 can abut the protruding structure on the spoke 1312 or the rim 1313.

[0041] Exemplarily, the clamping protrusion 232 is integrally formed with the clamping rod 231, and the clamping rod 231 is integrally formed with the decorative cover 21. In other embodiments, the clamping rod 231 can also be connected with the decorative cover 21 by clamping or screw connection, etc.

[0042] In some embodiments, the clamping member 22 comprises a clamping ring 221 and an operation part 222, the clamping ring 221 has two free ends, a variable gap 2211 is formed between the two free ends, and the operation part 222 is used to adjust the opening width of the variable gap 2211 to adjust the size of the area enclosed by the clamping ring 221. Exemplarily, the opening width of the variable gap 2211 is defined by the straight-line distance between the two free ends. When the opening width of the variable gap 2211 decreases, the area enclosed by the clamping ring 221 decreases, so that the clamping rod 231 surrounded by the clamping ring 221 is deformed in the direction of the center line of the rim 1313 to move the clamping protrusion 232 towards the clamping hole 1312a and away from the spoke 1312, and then the decorative cover 21 is moved away from the spoke 1312 along the width direction of the wheel 131, i.e. the decorative cover 21 can be removed. In some embodiments, the clamping ring 221 is an elastic ring with an opening formed by bending a steel rod. In other embodiments, the clamping ring 221 can also be a ring structure with an opening formed by a steel wire or other materials. In other embodiments, the clamping ring 221 can also be a closed ring structure formed by a steel wire, and the corresponding clamping ring 221 is switched to the clamping state by winding the steel wire.

[0043] The clamping piece 23 is provided with a limiting groove 233 for accommodating the clamping ring 22, and the limiting groove 233 can restrict the movement of the clamping ring 22 relative to the clamping piece 23 in the axial direction of the rim 1313. It can be understood that, in the radial direction of the rim 1313, the limiting groove 233 is located on the side of the clamping rod 231 away from the center line of the rim 1313. When the clamping ring 22 is switched from the loose state to the clamping state, the clamping ring 22 moves towards the groove bottom of the corresponding limiting groove 233 and abuts against the groove bottom of the limiting groove 233. The limiting groove 233 is located at the end of the clamping piece 23 away from the decorative cover 21, and the opening of the limiting groove 233 is arranged in the direction away from the central axis of the rim 1313. The end of the clamping piece 23 away from the decorative cover 21 is provided with a guide surface 234, and the distance between the guide surface 234 and the decorative cover 21 gradually decreases in the direction gradually away from the central axis of the rim 1313.

[0044] Referring to Figure 6 and Figure 7 In some embodiments, the operation part 222 is in a closed ring shape, and the two free ends of the clamping ring 221 are respectively provided with a connecting part 2212, both of which are connected to the operation part 222, and at least one of which can slide along the operation part 222. In some embodiments, the connecting part 2212 is curved and wound around the operation part 222, and the connecting part 2212 can slide relative to the operation part 222 in the extension direction of the operation part 222.

[0045] The operation part 222 has a clamping position 2221 and a loose position 2222, and when the connecting part 2212 slides from the loose position 2222 to the clamping position 2221, the opening width of the variable gap 2211 changes from large to small. In some embodiments, the operation part 222 also has a protruding position 2223, which is located between the clamping position 2221 and the loose position 2222 in the extension direction of the operation part 222. The opening width of the variable gap 2211 can be denoted as D1 when the connecting part 2212 slides to the protruding position 2223, and the opening width of the variable gap 2211 can be denoted as D2 when the connecting part 2212 slides to the clamping position 2221, and D1 is less than D2. Since D1 is less than D2, further deformation of the clamping ring 221 is required under the action of external force to make the connecting part 2212 pass the protruding position 2223 and slide to the loose position 2222 from the clamping position 2221, so that the connecting part 2212 can be stably placed at the position of the clamping position 2221 without the action of external force, so that the clamping ring 221 can be stably clamped.

[0046] In some embodiments, the operation part 222 is provided in a symmetrical structure, and a reference surface 202 is defined as a symmetrical surface of the operation part 222. Two sets of the tightening position 2221, the protruding position 2223 and the loose position 2222 are symmetrically arranged along the reference surface 202. The distance between the two tightening positions 2221 is smaller than the distance between the two loose positions 2222, and the distance between the two protruding positions 2223 is smaller than the distance between the two tightening positions 2221. One of the connecting parts 2212 can slide between one set of the tightening position 2221, the protruding position 2223 and the loose position 2222, and the other connecting part 2212 can slide between the other set of the tightening position 2221, the protruding position 2223 and the loose position 2222. When the two connecting parts 2212 slide to the corresponding tightening positions 2221 respectively, the clamping ring 221 is in the clamping state; when the two connecting parts 2212 slide to the two loose positions 2222 respectively, the clamping ring 221 is in the loose state.

[0047] In other embodiments, one of the connecting parts 2212 is fixedly connected with the operation part 222, and the other connecting part 2212 can slide relative to the operation part 222. By sliding the connecting part 2212 that can slide from the tightening position 2221 to the loose position 2222, the opening width of the variable gap 2211 can be adjusted to adjust the size of the area surrounded by the clamping ring 221.

[0048] In other embodiments, the operation part 222 can also include a bolt and a nut, the bolt is inserted into the two connecting parts 2212 and screwed with the nut, and by screwing the nut, the distance between the two connecting parts 2212 can be adjusted to achieve the effect of adjusting the opening width of the variable gap 2211. In other embodiments, the operation part 222 can be other structures that can adjust the opening width of the variable gap 2211.

[0049] In some embodiments, the clamping part 22 is arranged on the side of the spoke 1312 away from the decorative cover 21.

When the clamping part 22 separates the clamping protrusion 232 from the spoke 1312, the decorative cover 21 can be moved away from the spoke 1312 along the axial direction of the rim 1313 to move the clamping protrusion 232 into the clamping hole 1312a. When the clamping part 22 abuts against the spoke 1312, the clamping protrusion 232 is separated from the clamping hole 1312a, so that the decorative cover 21 can be separated from the spoke 1312. In other embodiments, the clamping part 22 can be arranged between the spoke 1312 and the decorative cover 21. For example, an operation hole can be provided on the decorative cover 21, and the clamping part 22 can be operated through the operation hole to switch the clamping part 22 from the loose state to the clamping state.

[0050] Reference Figure 2and Figure 5 In some embodiments, the wheel rim 1313 is provided with a limiting portion 1313a, and the decorative cover 21 is provided with a cooperating portion 211, the limiting portion 1313a is inserted into the cooperating portion 211 to restrict the rotation of the decorative cover 21 around the axis of the wheel rim 1313 relative to the wheel spoke 1312. In some embodiments, the limiting portion 1313a extends along the radial direction of the wheel rim 1313 to the axis of the wheel rim 1313 in a protruding manner, and the limiting portion 1313a is integrally formed with the wheel rim 1313; the cooperating portion 211 is in a groove shape, and the cooperating portion 211 is integrally formed with the decorative cover 21. By inserting and cooperating the limiting portion 1313a and the cooperating portion 211, the rotation of the decorative cover 21 around the axis of the wheel rim 1313 relative to the wheel rim 1313 is restricted, so that the decorative cover 21 is stably connected with the wheel spoke 1312.

[0051] In other embodiments, the cooperating portion 211 can be in a protruding shape, and the limiting portion 1313a is in a groove shape or a hole shape.

[0052] When it is necessary to disassemble the decorative cover 21, the clamping member 22 can simultaneously separate the plurality of clamping members 23 from the wheel spoke 1312 after the clamping member 22 is switched from the loose state to the clamping state, so that the decorative cover 21 can be quickly disassembled, and the operation is relatively simple, time-saving and labor-saving.

[0053] In addition, those skilled in the art should understand that the above embodiments are only used to illustrate the present application, and are not used as a limitation to the present application, and any appropriate changes and modifications to the above embodiments within the spirit and principles of the present application are within the scope of the present application.
