[0026] Specifically, the power mechanism of the toy car drives the shaft 32 to rotate, and then drives the driving part 31 to rotate, the driving part 31 drives the wheel hub 2, and the wheel hub 2 drives the tire 1. When the external force applied to the tire 1 is too large, the driving part 31 of the axle 3 and the wheel hub 2 will rotate relative to each other, avoiding damage to the toy wheel. The contact area between the reinforced protrusion 41 and the driving part 31 is small, which can not only play the role of limiting the axle 3 but also reduce friction, reducing the probability of damage when the driving part 31 of the axle 3 and the wheel hub 2 rotate relative to each other, and solving the problem that the axle 3 and the wheel hub 2 are easily separated and damaged when the external force is too large.

[0027] Furthermore, in some embodiments, the driving portion 31 includes a driving portion body 311 and an abutting protrusion 312 that protrudes circumferentially from the driving portion body 311 , the circumferential surface of the abutting protrusion 312 abuts against the inner wall of the mounting groove 21 , and the reinforcing protrusion 41 abuts against the side wall of the abutting protrusion 312 .

[0028] Specifically, the shaft 32 drives the driving part body 311 and the abutting protrusion 312 to rotate, the abutting protrusion 312 drives the wheel hub 2, and the reinforcing protrusion 41 limits the driving part 31 by abutting against the side wall of the abutting protrusion 312. The axle baffle 4 is provided with an air avoidance hole for the driving part body 311 to pass through.

[0029] Furthermore, in some embodiments, the driving portion body 311 includes a first portion and a second portion, and the diameter of the first portion is greater than the diameter of the second portion.

[0030] Specifically, the driving part body 311 is in a stepped shape, and the radius decreases gradually from the abutting protrusion 312 to the shaft rod 32 to form a transition, thereby avoiding direct connection between the shaft rod 32 and the abutting protrusion 312 of the driving part body 311, avoiding excessive stress concentration, and reducing the chance of damage to the axle 3.

[0031] Furthermore, in some embodiments, the toy wheel also includes an inner baffle 5; the inner baffle 5 is arranged in the mounting groove 21, between the driving portion 31 and the bottom of the mounting groove 21; a protruding hemispherical protrusion 51 is provided on the middle part of the inner baffle 5 toward the bottom of the mounting groove 21, and the hemispherical protrusion 51 presses against the bottom of the mounting groove 21.

[0032] Specifically, the inner baffle 5 can fill the gap between the driving portion 31 and the bottom of the mounting groove 21 to prevent the driving portion 31 from swinging left and right in the mounting groove 21, so that the toy wheel can roll normally in a straight line; and the hemispherical protrusion 51 presses against the bottom of the mounting groove 21 to reduce the friction between the inner baffle 5 and the wheel hub 2, thereby reducing the resistance when the axle 3 and the wheel hub 2 are relatively displaced.

[0033] Furthermore, in some embodiments, the hub 2 is provided with a decorative hole 22 communicating with the outside and the mounting groove 21 .

[0034] Specifically, the decorative hole 22 can have a decorative effect, making the toy wheel more beautiful, and can also reduce the amount of production materials and reduce production costs; and the inner baffle 5 can play the role of shielding the observable area of ​​the decorative hole 22, making the toy wheel more beautiful, and can also block some debris from entering the gap between the axle 3 and the mounting groove 21, preventing the debris from affecting the normal operation of the toy wheel.

[0035] Furthermore, in some embodiments, the driving portion 31 is hollow inside, and an opening 313 is provided at one end of the driving portion 31 facing the bottom of the mounting groove 21 . The inner baffle 5 is provided with an inserting protrusion 52 at one end facing the driving portion 31 , and the inserting protrusion 52 is inserted into the opening 313 .

[0036] Specifically, the plug-in protrusion 52 is inserted into the opening 313 to assemble the axle 3 and the inner baffle 5 together.

[0037] Furthermore, in some embodiments, the shaft 32 is hollow, and the hollow portion of the shaft 32 is communicated with the hollow portion of the driving portion 31 .

[0038] Specifically, the hollow shaft 32 can reduce the material used for the shaft 32 and reduce the cost of the axle 3 .

[0039] Furthermore, in some embodiments, the reinforcing protrusion 41 is in the shape of a ring or a plurality of sub-protrusions distributed in a ring shape.

[0040] Specifically, in some embodiments, the reinforcing protrusion 41 is an integral ring; in some embodiments, the reinforcing protrusion 41 is composed of a plurality of sub-protrusions distributed in a ring; the specific design and production are based on actual needs.

[0041] Furthermore, in some embodiments, the axle 3 is an integral component.

[0042] Specifically, the axle 3 being an integral component can provide the axle 3 with better strength, allowing the axle 3 to better perform its function.

[0043] Furthermore, in some embodiments, the axle baffle 4 and the wheel hub 2 are connected by interference fit, adhesive bonding or threaded connection.

[0044] Specifically, the axle baffle 4 needs to be well fixedly connected to the wheel hub 2 so that the axle baffle 4 can effectively limit the axle 3. The axle baffle 4 and the wheel hub 2 are fixed by connection methods including but not limited to interference fit connection, adhesive connection or threaded connection.

[0045] The present application also provides a toy car, which adopts the above-mentioned toy wheels.

[0046] The present invention provides a toy wheel and a toy car. The power mechanism of the toy wheel and toy car drives the shaft 32 to rotate, thereby driving the driving part 31 to rotate, the driving part 31 drives the wheel hub 2, and the wheel hub 2 drives the tire 1. When the external force applied to the tire 1 is too large, the driving part 31 of the axle 3 and the wheel hub 2 will rotate relative to each other, thereby avoiding damage to the toy wheel. In addition, the contact area between the reinforced protrusion 41 and the driving part 31 is small, which not only plays the role of limiting the axle 3 but also reduces friction, thereby reducing the probability of damage when the driving part 31 of the axle 3 and the wheel hub 2 rotate relative to each other, thereby solving the problem that the axle 3 and the wheel hub 2 are easily separated and damaged when the external force is too large.
