In normal use, the rotating axle is parallel to the movable axle. The movable axle and the axle can be embedded in the hollow tube and positioned by the first buckle to prevent sliding in the horizontal position. At this time, the tire is perpendicular to the hollow tube, which is a normal driving state. When folding the wheel, pull the wheel to expose the hollow tube body completely, and then turn to the wheel shaft so that it is perpendicular to the movable shaft. At this time, the wheel is parallel to the hollow tube body and is in a folded state. By cooperating with the second buckle, the wheel axle is locked and positioned at the opening of the hollow tube body to maintain the folded state of the wheel. In addition, the entire folding structure can be accommodated in the hollow tube body, with a very small space occupation, and can be applied to balance cars of different styles.

[0035] The terminology used here is only for describing specific embodiments and is not intended to limit the exemplary embodiments. Unless the context clearly dictates otherwise, the singular forms "a" and "one" used herein are also intended to include the plural. It should also be understood that the terms "including" and/or "comprising" used herein specify the existence of the stated features, integers, steps, operations, units and/or components, and do not exclude the existence or addition of one or more Other features, integers, steps, operations, units, components, and/or combinations thereof.
[0036] The following combination Figure 1-12 The concept of the present invention is further explained.
[0037] This embodiment discloses a balance vehicle, which includes a vehicle body; the vehicle body is provided with a wheel fixing structure. The wheel fixing structure includes a hollow tube body; the hollow tube body is sleeved with a movable shaft and a first buckle; the wheel shaft of the wheel can be sleeved into the hollow tube body; one end of the movable shaft is movably connected with the wheel shaft, and the other end is on the wheel shaft When stored in the hollow tube body, it is matched and fixed with the first buckle; the opening of the hollow tube body is provided with a second buckle which is matched and fixed with the side wall of the wheel axle when the wheel is folded. The buckle should be understood in a broad sense, and the conventional latch, circlip and other structures that can be used to fix the buckle should fall within the scope of the buckle of the present invention.
[0038] Optionally, a cap sleeve is sleeved at the opening of the hollow tube body; the aperture of the cap sleeve is smaller than the inner diameter of the hollow tube opening; the second snap is fixed on the cap sleeve. The cap sleeve is fixed at the opening of the hollow tube body by threads. The cap cover can facilitate the disassembly and assembly of the movable shaft and the wheel shaft.
[0039] The inner top surface and the bottom surface of the cap sleeve are both flat surfaces; correspondingly, the upper surface and the lower surface of the movable shaft are also flat surfaces, which cooperate with the inner top surface and the bottom surface of the cap sleeve to form a limit structure that restricts the rotation of the movable shaft. The inner diameter shape of the cap sleeve is used to limit the movable shaft to prevent the rotating shaft from rotating, so that there is no need to set a limit structure in the hollow tube, and the production cost is reduced.
[0040] The length of the axle is greater than the caliber of the cap sleeve. In this way, when the rotating shaft is perpendicular to the cap sleeve, that is, when the wheel is folded, the second buckle is clamped at the cap sleeve opening at the cap sleeve opening to realize automatic positioning.
[0041] The fixed end of the movable shaft and the wheel shaft is provided with a groove; the two inner walls of the groove are provided with a rotating shaft; correspondingly, the wheel shaft is embedded in the groove; the wheel shaft is provided with a through hole for the rotating shaft; When the wheel shaft rotates parallel to the movable shaft, the rotating shaft can be embedded in the hollow tube together with the movable shaft; when the rotating shaft rotates perpendicular to the movable shaft, the rotating shaft is fixed at the opening of the cap sleeve through the second buckle.
[0042] The wheel shaft includes a fixed part that is matched with the groove and a base connected to the fixed part; the end surface of the movable shaft at one end of the groove is a concave arc surface; the connection between the base and the fixed part is provided with a concave Convex curved surface adapted to the curved surface. The curved surface helps reduce friction when rotating the axle.
[0043] A disc is connected to the opposite end of the movable shaft and the wheel shaft; the outer diameter of the disc is consistent with the inner diameter of the hollow tube.
[0044] Optionally, the present invention does not necessarily require a cap, and it is also feasible to directly form a positioning structure of the spring and the movable shaft inside the hollow tube. This has fewer parts and a more compact structure. Specifically, the hollow tube body adopts a non-circular structure inside, which can be elliptical, rectangular, etc., of course, the top and bottom surfaces of the interior can also be flat; correspondingly, the upper and lower surfaces of the movable shaft are also flat. Cooperating with the inner top surface and bottom surface of the hollow tube body to form a limit structure that limits the rotation of the movable shaft. At this time, the length of the axle is greater than the inner diameter of the hollow tube body. The movable shaft, wheel shaft and other structures can refer to the previous description, and will not be repeated here.
[0045] Compared with the prior art, the technical effect of the present invention is that the present invention utilizes the cooperation of the hollow tube body, the movable shaft, the first buckle and the second buckle to realize the folding of the wheel of the balance vehicle. In normal use, the rotating axle is parallel to the movable axle. The movable axle and the axle can be embedded in the hollow tube and positioned by the first buckle to prevent sliding in the horizontal position. At this time, the tire is perpendicular to the hollow tube, which is a normal driving state. When folding the wheel, pull the wheel to expose the hollow tube body completely, and then turn to the wheel shaft so that it is perpendicular to the movable shaft. At this time, the wheel is parallel to the hollow tube body and is in a folded state. By cooperating with the second buckle, the wheel axle is locked and positioned at the opening of the hollow tube body to maintain the folded state of the wheel. In addition, the entire folding structure can be accommodated in the hollow tube body, with a very small space occupation, and can be applied to balance cars of different styles.
