[0024] In this embodiment, a balancing vehicle is provided, as shown in Fig. Figure 1 illustrates this balance vehicle. It comprises a vehicle frame 100, a wheel 200, and an assembly / disassembly mechanism. The wheel 200 can be mounted or dismounted at each end of the vehicle frame 100 using this mechanism. This balance vehicle is primarily designed to help children learn to walk and develop their sense of balance. To reduce the transport volume during packaging at the factory and during shipping, the wheels 200 are removed before shipment. Upon receipt, parents can mount the two front and rear wheels 200 onto the vehicle frame 100 according to the instruction manual. However, the assembly / disassembly mechanisms of the existing technology are not only complex but also make mounting and dismounting the wheels 200 from the vehicle frame 100 difficult, significantly impacting the user experience.

[0025] To solve this problem, this embodiment provides an assembly and disassembly structure for mounting and dismounting a wheel 200 on the vehicle frame 100. As shown in the Fig. As shown in Figures 2 to 4, this assembly and disassembly structure comprises a wheel axle 10, a locking component 20, and a separation component 30. The first end of the wheel axle 10 is pivotably connected to the wheel 200. A limiting groove 11 is arranged on the outer circumference of the second end. The second end can be inserted into the vehicle frame 100; the locking component 20 comprises a locking pin 21 and a locking seat 22, wherein a projecting limiting section 211 is arranged at one end of the locking pin 21, the locking seat 22 being mounted on the vehicle frame 100 and being able to push the locking pin 21 in the direction of the wheel axle 10 so that the limiting section 211 can be inserted accordingly into the limiting groove 11; The separating component 30 can release the limiting section 211 of the locking pin 21 from the limiting groove 11 in order to remove the wheel axle 10.

[0026] To mount the wheel 200, only the second end of the wheel axle 10 needs to be inserted into the vehicle frame 100. This allows the locking seat 22 to engage the limiting section 211 of the locking pin 21 in the limiting groove 11, thus securing the wheel axle 10 and preventing it from slipping out of the vehicle frame 100. Since the wheel 200 is rotatably connected to the first end of the wheel axle 10, it can rotate about its axis. To remove the wheel 200, only the release component 30 needs to be actuated. This releases the limiting section 211 of the locking pin 21 from the limiting groove 11. In this state, the wheel axle 10 is no longer secured. By pulling the wheel axle 10 away from the vehicle frame 10, the wheel 200 can be removed together with the wheel axle 10.The structure is not only simple, but also requires little assembly and disassembly effort, enabling quick assembly and disassembly and is efficient, which significantly improves the user experience.

[0027] In particular, the locking component 20 comprises, as shown in the Fig. Figures 2 to 4 show a first elastic element 23, wherein one end of the first elastic element 23 rests against the locking pin 21, while the other end rests against the locking seat 22. The elastic force of the first elastic element 23 can cause the limiting section 211 to engage in the limiting groove 11. Since the locking seat 22 is mounted on the vehicle frame 100 and is thus fixed, the elastic force of the first elastic element 23 can push the locking pin 21 away from the locking seat 22 until the limiting section 211 of the locking pin 21 engages in the limiting groove 11, thereby completing the locking action. The entire process is simple and smooth, requiring no manual locking, as the first elastic element 23 automatically completes the locking action.

[0028] It should be noted that the limiting groove 11 is an annular groove. This means that after the wheel axle 10 has rotated through any angle and been inserted into the vehicle frame 100, the limiting section 211 can always engage appropriately in the annular groove. This eliminates the need for alignment during assembly, saving time and effort.

[0029] Furthermore, the limiting section 211 is provided with a guide chamfer, whereby, after the wheel axle 10 is inserted into the vehicle frame 100, the second end can slide against the guide chamfer and drive the locking pin 21 to compress the first elastic element 23. The provision of a guide chamfer on the limiting section 211 reduces the resistance when inserting the wheel axle 10 into the vehicle frame 100, thus increasing the smoothness of the insertion process and further improving ease of assembly. Once the limiting section 211 slides towards the limiting groove 11, the elastic force of the first elastic element 23 can push the locking pin 21 towards the limiting groove 11, causing the limiting section 211 to engage in the limiting groove 11.In other embodiments, a guide ramp can additionally be attached to the second end of the wheel axle 10 to further increase assembly efficiency and speed.

[0030] As in Fig. As shown in Figure 2, the locking pin 21 is further provided with a mounting groove 212 on the side facing away from the limiting section 211, wherein the first elastic element 23 is positioned in the mounting groove 212 and rests against the bottom of the mounting groove 212. The arrangement of the mounting groove 212 allows the end of the first elastic element 23, which rests against the locking pin 21, to be limited in order to prevent wobbling during extension and retraction and to ensure good stability.

[0031] Furthermore, as in Fig. Figure 3 shows the locking seat 22 on the side facing the vehicle frame 100 being provided with a first receiving groove 221, wherein the first elastic element 23 is positioned in the first receiving groove 221 and rests against the bottom of the first receiving groove 221. The arrangement of the first receiving groove 221 allows the end of the first elastic element 23, which rests against the locking seat 22, to be limited in order to prevent wobbling during extension and retraction and to ensure good stability.

[0032] As in the Fig. As shown in Figures 2 to 4, the separating component 30 comprises a separating element 31, the separating element 31 being provided with a sliding part 311, the sliding part 311 being able to enter the locking seat 22 and come into contact with the locking pin 21. When the separating element 31 is pushed towards the inner wall of the locking seat 22, the sliding part 311 can push the locking pin 21, so that the limiting section 211 can be released from the limiting groove 11. This arrangement is not only simple in design but also user-friendly. It is sufficient to push the separating element 31 to cause the limiting section 211 to be released from the limiting groove 11, thereby allowing the wheel axle 10 to be removed from the vehicle frame 100 – simply and efficiently.

[0033] In particular, the separation component 30 comprises, as in the Fig. Figures 2 to 4 show a second elastic element 32, wherein one end of the second elastic element 32 rests against the separating element 31, while the other end rests against the locking seat 22. The locking seat 22 is provided with a mounting hole 222, the end of the separating element 31 facing away from the sliding part 311 being provided with a step 314. The separating element 31 is mounted in the mounting hole 222, and the elastic force of the second elastic element 32 can press the step 314 against the outer circumferential wall of the mounting hole 222. Since the separating element 31 is mounted in the mounting hole 222, protrusion of the structure is prevented. After the separating element 31 has been pressed into the locking seat 22, the second elastic element 32 can reset the separating element 31 to allow for its next use.At the same time, the elastic force of the second elastic element 32 can press the step 314 of the separating element 31 against the outer circumferential wall of the mounting hole 222 to prevent it from popping out of the mounting hole 222, while the end of the step 314 can protrude from the mounting hole 222 so that an operator can push the separating element 31 inwards, further increasing ease of use.

[0034] It should be emphasized that, as in Fig. Figure 3 shows that a second receiving groove 313 is arranged in the separating element 31, wherein the second elastic element 32 is positioned in the second receiving groove 313 and rests against the bottom of the second receiving groove 313. The arrangement of the second receiving groove 313 allows the end of the second elastic element 32, which rests against the separating element 31, to be limited in order to prevent wobbling during extension and retraction and to ensure good stability.

[0035] Furthermore, it should be explained that in this embodiment, both the first elastic element 23 and the second elastic element 32 are springs. Springs are simple in design, cost-effective, easy to install and use, and can effectively reduce manufacturing costs as well as assembly and disassembly effort.

[0036] As in Fig. As shown in Figure 4, the sliding part 311 and the locking pin 21 fit together due to a complementary concave-convex shape. This concave-convex fit between the sliding part 311 and the locking pin 21 ensures the stability of the connection between them, thus guaranteeing the disassembly effect when sliding the separating element 31 and improving the user experience.

[0037] In particular, as in the Fig. 3 and Fig.As shown in Figure 4, the locking pin 21 is provided with a projection 213 on both sides. The separating element 31 is provided with a sliding part 311 on both sides, the ends of which are each provided with a groove 312. This arrangement ensures an even distribution of force on both sides of the locking pin 21, while the fit between the projection 213 and the groove 312 ensures the stability of the connection. This results in a good sliding effect, which ensures that when the separating element 31 is pushed towards the interior of the locking seat 22, sufficient force is present to release the limiting section 211 from the limiting groove 11 without tilting. The structure is simple and allows for high disassembly efficiency.

[0038] The following explains the usage process of the assembly and disassembly structure in this exemplary embodiment with reference to the drawings: First, the locking component 20 and the separating component 30 are mounted on the vehicle frame 100.

[0039] Next, the end of the wheel axle 10, the one furthest from the wheel 200, is inserted into the vehicle frame 100 until the limiting section 211 clicks into the limiting groove 11, thus completing the assembly. At this point, the balance bike can be used by children.

[0040] Finally, after the balance vehicle has been used, the separating element 31 is pressed towards the interior of the locking seat 22, whereby the pushing element 311 can push the projection 213 of the locking pin 21 to release the limiting section 211 from the limiting groove 11. Now the wheel axle 10 can be removed from the vehicle frame 100, thus completing the disassembly.

[0041] In summary, the assembly and disassembly structure in this embodiment is not only simple in design but also requires minimal operator effort and enables high assembly and disassembly speeds. Applying this assembly and disassembly structure to a balancing vehicle significantly improves the user experience.

[0042] It is obvious that the embodiments of the present utility model described above serve only to clarify the present utility model and do not constitute a limitation of the embodiments of the present utility model.
