[0045] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0046] like Figures 1 to 7As shown, this embodiment provides a wheel quick-release assembly, comprising a fixing tube 1, a wheel, and a locking member. The fixing tube 1 is connected to the vehicle frame 8, and the fixing tube 1 is at least partially inserted into the mounting cavity of the vehicle frame 8. The wheel comprises a wheel body and a wheel axle 2. The wheel axle 2 is connected to the rotation center of the wheel body. The outer peripheral surface of the wheel axle 2 is provided with a locking groove 21. The wheel axle 2 can be inserted into the inner cavity of the fixing tube 1 and is at least partially located within the mounting cavity. The locking member comprises a wrench 3, a latch 4, and an elastic member 5. The wrench 3 is partially inserted into the mounting cavity and is rotatably connected to the vehicle frame 8. The latch 4 and the elastic member 5 are both located within the mounting cavity. The first end of the latch 4 is rotatably inserted into the mounting hole 321 of the wrench 3. The elastic member 5 is used to ensure that the wrench 3 always has a force toward one side of the wheel axle 2, so that the second end of the latch 4 can pass through the limiting hole on the fixing tube 1 and be inserted into the locking groove 21, thereby achieving the latch 4 locking the wheel axle 2 within the mounting cavity. When the wheel axle 2 needs to be unlocked, an external force can be applied to the wrench 3 to rotate the wrench 3 toward the side away from the wheel axle 2 and squeeze the elastic member 5, so that the wrench 3 can drive the latch 4 rotatably connected thereto to move toward the side away from the wheel axle 2, thereby allowing the second end of the latch 4 to disengage from the locking groove 21, thereby unlocking the wheel axle 2 with the latch 4, allowing the wheel axle 2 to be removed from the installation cavity. In addition, the axial direction of the latch 4 is perpendicular to the axial direction of the wheel axle 2, and the locking groove 21 is circumferentially arranged on the outer circumference of the wheel axle 2. When the latch 4 is inserted into the locking groove 21, the latch 4 will not interfere with the rotation of the wheel axle 2, but will only hinder the movement of the wheel axle 2 along its own axial direction. The fixing tube 1 and the locking member of the wheel quick-release assembly provided in this embodiment can be installed on the frame 8 in advance. When the wheel needs to be connected to the frame 8, an external force can be applied to the wrench 3 first to rotate the wrench 3 toward the side away from the fixing tube 1, so that the latch 4 can leave the locking position, and then the wheel axle 2 is inserted into the fixing tube 1. The external force applied to the wrench 3 is then released, and the elastic member 5 forces the wrench 3 to rotate toward the frame 8, that is, the wheel axle 2, so that the latch 4 can return to the locking position, that is, the position where the latch 4 is inserted into the locking groove 21, thereby realizing the connection between the wheel and the frame 8.

[0047] In specific implementation, the fixing tube 1 is coaxially disposed with the wheel axle 2. The shape of the limiting hole in the fixing tube 1 matches the outer shape of the latch 4. Specifically, the limiting hole is used to restrict the latch 4 to movement along its own axis, preventing rotation about its first end. This ensures that when no external force is applied to the wrench 3, the latch 4 remains positioned within the locking groove 21, thereby maintaining the locking effect of the wheel quick-release assembly. In this embodiment, the vehicle frame 8 is provided with a first cavity and a second cavity communicating with the mounting cavity. The locking member can be partially inserted into the mounting cavity through the first cavity, while the fixing tube 1 can be partially inserted into the mounting cavity through the second cavity.

[0048] Optionally, an anti-slip strip 323 is provided on the portion of the wrench 3 outside the mounting cavity. This strip 323 increases friction between the user and the wrench 3 when the user applies external force, facilitating rotation of the wrench 3. In this embodiment, clockwise rotation of the wrench 3 moves the latch 4 away from the stationary tube 1, releasing the latch 4 from the wheel axle 2. This allows the user to simply press down on the anti-slip strip 323 on the wrench 3, making operation convenient.

[0049] Alternatively, as Figures 1 to 4 As shown, the locking member also includes a fixing seat 6, which is fixed at the first cavity. In this embodiment, the position where the frame 8 is connected to the wheel is a tubular structure, the installation cavity is the inner cavity of the tubular structure, and the end of the tubular structure is the first cavity of the installation cavity. The fixing seat 6 is fixed at the first cavity. The fixing seat 6 is used to limit the wrench 3 from being partially inserted into the installation cavity and not being detached from the first cavity. Specifically, a through groove 60 is provided on the fixing seat 6, and the wrench 3 includes a first part 31 and a second part 32. The first part 31 is located in the installation cavity, the elastic member 5 is clamped between the first part 31 and the fixing seat 6, and the second part 32 is inserted into the through groove 60. The raised edge 322 of the second part 32, which is away from the first part 31 in the axial direction of the latch 4, is located outside the installation cavity, and the raised edge 322 presses against the first cavity. That is, when the elastic member 5 is in the compressed state, its two ends respectively abut against the first portion 31 and the fixing seat 6, so that the wrench 3 always has a tendency to move toward the side of the fixed tube 1, and the raised edge 322 abuts against the first cavity opening to limit the minimum distance between the wrench 3 and the fixed axis, thereby preventing the wrench 3 from slipping into the installation cavity.

[0050] In this embodiment, Figure 1 As shown, the second portion 32 is provided with a first rotation hole 324 and a second rotation hole 325. The locking member further includes a first rotating shaft and a second rotating shaft. The first rotating shaft rotatably extends through the first rotation hole 324 and is connected to the latch 4. The second rotating shaft extends through the second rotation hole 325 and is rotatably connected to the fixing base 6. The fixing base 6 is also provided with a first fixing hole 613. The frame 8 is provided with a first through hole corresponding to the first fixing hole 613. The locking member further includes a first fixing member that extends through the first through hole in the frame 8 and is connected to the first fixing hole 613, thereby achieving a fixed connection between the fixing base 6 and the frame 8. In a specific embodiment, when an external force is applied to the wrench 3 to rotate the wrench 3 clockwise, since the fixing base 6 is fixed to the frame 8, the wrench 3 will rotate relative to the fixing base 6 about the second rotating shaft as the rotation center. The wrench 3 will also rotate relative to the latch 4 about the first rotating shaft as the rotation center, thereby synchronously driving the latch 4 to move away from the fixing tube 1. In addition, the distance that the latch 4 can move toward the side away from the fixed tube 1 mainly depends on the angle at which the wrench 3 can rotate relative to the fixed seat 6, and this rotation angle must ensure that the latch 4 is always inserted into the limiting hole of the fixed tube 1.

[0051] In specific implementation, the first end of latch 4 is rotatably inserted into mounting hole 321 of wrench 3. Specifically, the inner diameter of mounting hole 321 must be larger than the outer diameter of latch 4 to ensure that wrench 3 has room to rotate relative to latch 4. In this embodiment, mounting hole 321 is a waist-shaped hole with its length oriented vertically. This ensures that when wrench 3 rotates, even if latch 4 is restricted by the stopper hole and cannot rotate about its first end, latch 4 will not hinder rotation of wrench 3. Instead, it will alter the angle between the axial direction of latch 4 and the axial direction of mounting hole 321. However, in other embodiments, mounting hole 321 may alternatively be a circular hole, with dimensions larger than those of latch 4, to ensure that wrench 3 can rotate relative to latch 4.

[0052] Optionally, a limiting groove 311 is provided on the side of the first portion 31 facing the elastic member 5, and one end of the elastic member 5 is disposed in the limiting groove 311. The depth of the limiting groove 311 is the axial direction of the latch 4. The provision of the limiting groove 311 can prevent the elastic member 5 from deforming or moving in any direction other than the axial direction of the latch 4 during use.

[0053] Optionally, a limiting post 611 is provided on the side of the fixing base 6 facing the elastic member 5, and the other end of the elastic member 5 is sleeved on the limiting post 611. The axial direction of the limiting post 611 is the axial direction of the latch 4. The provision of the limiting post 611 can also prevent the elastic member 5 from deforming and moving in any direction other than the axial direction of the latch 4 during use.

[0054] Furthermore, the fixing seat 6 includes a fixing portion 61 and a limiting portion 62. The fixing portion 61 is disposed within the mounting cavity and is connected to the vehicle frame 8, while the limiting portion 62 is located outside the mounting cavity and abuts the first cavity opening of the mounting cavity. The fixing portion 61 and the limiting portion 62 form a stepped surface in the axial direction of the latch 4. When the fixing seat 6 is inserted into the first cavity opening, the stepped surface abuts the first cavity opening to limit the installation depth of the fixing seat 6 at the first cavity opening. The first fixing hole 613 and the second through hole 612 corresponding to the second rotation hole 325 are both provided in the fixing portion 61. When the fixing seat 6 is installed in place, the first fixing hole 613 will be concentric with the first through hole, while the second through hole 612 will be concentric with the second rotation hole 325, facilitating the assembly of the first fixing member and the second rotating shaft.

[0055] During specific implementation, the raised edge 322 will also press against the first cavity opening to limit the installation depth of the wrench 3 at the first cavity opening. After the wrench 3 is installed in place, the first rotating hole 324 on the wrench 3 will also be concentric with the third through hole 41 set on the pin 4, facilitating the assembly of the first rotating shaft.

[0056] Furthermore, the wheel quick-release assembly also includes a bushing 7, which is mounted on the wheel axle 2 and located within the inner cavity of the fixing tube 1. In this embodiment, the vehicle frame 8, fixing tube 1, and wheel axle 2 are all metal frames, while the bushing 7 is a plastic component. The fixing tube 1 is welded to the vehicle frame 8, and the bushing 7 is installed between the wheel axle 2 and the fixing tube 1. This prevents direct contact between the fixing tube 1 and the wheel axle 2, thereby reducing wear on both and extending the service life of the wheel axle 2 and the fixing tube 1. The bushing 7 is detachably connected to the wheel axle 2 and the fixing tube 1, making it easy to replace the bushing 7.

[0057] Optionally, a positioning protrusion is provided on one of the bushing 7 and the fixing tube 1, and a positioning groove is provided on the other, with the positioning protrusion being inserted into the positioning groove. In this embodiment, the positioning protrusion is provided on the end edge of the bushing 7, and the positioning groove is provided on the end edge of the fixing tube 1. When the bushing 7 is inserted into the fixing tube 1 along the axial direction of the fixing tube 1, the positioning protrusion can be inserted into the positioning groove. A fourth through hole is provided on the bushing 7. When the bushing 7 is installed in place, the fourth through hole is concentric with the limiting hole on the fixing tube 1, and the latch 4 can simultaneously pass through the limiting hole and the fourth through hole and be inserted into the locking groove 21.

[0058] This embodiment also provides a balance vehicle, comprising a frame 8 and the aforementioned wheel quick release assembly, wherein the wheel quick release assembly is connected to the frame 8. Figure 6 and Figure 7 As shown, the wheel quick-release assembly includes a fixing tube 1, a wheel and a locking piece. The frame 8 has an installation cavity. The fixing tube 1 is arranged at the first cavity opening of the installation cavity. The locking piece is arranged at the second cavity opening of the installation cavity. The wheel is inserted into the fixing tube 1 through the wheel axle 2, and the wheel axle 2 can be quickly locked and unlocked with the pin 4 of the locking piece, saving time and effort.

[0059] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications are possible without departing from the spirit and scope of the present invention. Such changes and modifications are within the scope of the present invention.
