[0004] Although this bracket can assist construction workers in repairing tires on electric tricycles, it requires the construction workers to lift the electric tricycle frame onto the bracket, which is time-consuming and labor-intensive. In addition, the bracket is designed for the frame of a sidecar three-wheeled motorcycle, and there is currently no bracket structure that can match the frame of an electric tricycle used at a construction site. Therefore, it is necessary to provide an electric tricycle repair bracket that can solve the problem that there is no bracket structure in the prior art that can match the frame of an electric tricycle used at a construction site. Summary of the Invention

[0019] In the figure, 1 is a lever arm, 2 is a wheel arm, 3 is a support rod, 4 is a support bracket, 5 is a reinforcing rib, 6 is a handle, and 7 is a moving wheel. DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Please see the attached Figure 1 , a maintenance stand for an electric tricycle, comprising a lever arm 1, a wheel arm 2, a support rod 3, a support bracket 4 and a moving wheel 7; one end of the lever arm 1 is vertically connected to one end of the support rod 3 to form an L-shaped structure, the middle part of the wheel arm 2 is connected to both sides of the connection node between the lever arm 1 and the support rod 3, and the two ends of the wheel arm 2 extend to both sides of the lever arm 1 and the support rod 3 respectively, and a pair of moving wheels 7 are rotatably mounted on the two ends of the wheel arm 2; the support bracket 4 is arranged at the other end of the support rod 3, and when the lever arm 1 and the wheel arm 2 are placed on the ground, the support bracket 4 is vertically erected through the support rod 3, and the frame rods of the electric tricycle are placed on the support bracket 4.

[0022] Construction workers raise lever arm 1, forming a V-shaped structure with support rod 3 above the ground. Movable wheels 7, mounted on both ends of wheel arms 2, allow the entire support to be flexibly moved around the construction site. Once the support is positioned next to the electric tricycle to be repaired, the angle between support rod 3 and the ground can be adjusted by rotating lever arm 1, thereby adjusting the height of support bracket 4.

[0023] When the support bracket 4 is adjusted to below the rod member of the electric tricycle frame that needs to be supported, the lever principle can be used to press the force arm 1 downward to rotate the support rod 3 upward, thereby lifting the electric tricycle frame upward through the support bracket 4, so that the electric tricycle wheel frame is set high, which is convenient for disassembly, replacement or repair of the electric tricycle wheel, saving time, effort and labor.

[0024] The support bracket 4 can be made according to the rod to be supported so that it can support the rod to be supported. The entire bracket structure is simple and has good matching and applicability to the electric tricycle frame at the construction site.

[0025] The distance between the two ends of the opening of the support bracket 4 is greater than the thickness of the support rod 3 , and reinforcing ribs 5 are respectively provided between the two ends of the opening of the support bracket 4 and the support rod 3 .

[0026] If the rod to be supported is large, the distance between the two ends of the opening of the support bracket 4 will also be correspondingly large. In order to improve the support stability of the support bracket 4 on the rod to be supported and prevent deformation and damage of the support bracket 4, the end support strength of the support bracket 4 can be increased by using reinforcing ribs 5. The reinforcing ribs 5 transfer the end load of the support bracket 4 to the support rod 3. The length of the reinforcing ribs 5 can be adaptively selected according to the actual load requirements.

[0027] The support rod 3, support bracket 4 and reinforcing rib 5 are connected into an integrated structure, so that the supporting node has high strength, strong load capacity, and is not easy to deform or damage. It can be made by welding steel pipes, which is easy to obtain materials and manufacture, and can be customized according to the support requirements of the electric tricycle frame, with good adaptability and versatility.

[0028] The support bracket 4 is in an arc-shaped structure, and the axial direction of the support bracket 4 is parallel to the axial direction of the wheel arm 2 and perpendicular to the axial direction of the lever arm 1 and the axial direction of the support rod 3.

[0029] If the rod to be supported is a rod with a circular cross-section, a support bracket 4 with an arc-shaped structure can be used, which can provide a larger contact area and optimal shape matching, thereby ensuring stable support for the electric tricycle frame. Other shapes of support brackets 4 can also be used according to the actual shape of the supported rod.

[0030] The other end of the lever arm 1 is provided with a handle 6 , which is connected to the lever arm 1 to form an integral structure.

[0031] By providing the handle 6 , the lever arm 1 can be gripped more conveniently and easily, and the rotation control of the lever arm 1 is also facilitated.

[0032] The force arm rod 1, wheel arm 2 and support rod 3 are vertically connected in pairs.

[0033] The lever arm 1 and the wheel arm 2 can be located in the same plane, and the wheel arm 2 and the support rod 3 can be located in the same plane, so that the bracket can be stably placed on the ground, and the support bracket 4 stably supports the frame of the electric tricycle upward.

[0034] The force arm 1, wheel arm 2, support rod 3 and support bracket 4 are connected into an integrated structure, so that the entire bracket has higher structural strength and integrity, thereby ensuring its load performance.

[0035] The length of the lever arm 1 is greater than that of the support rod 3 .

[0036] The length of the lever arm 1 can be adaptively adjusted according to actual use requirements, making the lever arm longer and more labor-saving when lifting the electric tricycle frame. The length of the support rod 3 can be adaptively adjusted according to the installation height of the electric tricycle frame, so as to facilitate the maintenance and replacement of the electric tricycle wheels.

[0037] Please see the attached Figure 1 , the manufacturing method of the utility model is:

[0038] The lever arm 1 and support rod 3 are made of square steel pipes, while the wheel arm 2 is made of round steel pipe. A circular groove matching the diameter of the wheel arm 2 is cut at one end of the lever arm 1. The middle of the wheel arm 2 is inserted into the circular groove and welded in place. One end of the support rod 3 is welded to the outer wall of one end of the lever arm 1, vertically connecting the lever arm 1, wheel arm 2, and support rod 3 into a single unit.

[0039] Support bracket 4 is made of arc-shaped steel plate. Its dimensions are tailored to the desired supporting components of the electric tricycle frame, ensuring reliable support. The center of support bracket 4 is welded to the other end of support rod 3. Typically, the supporting components on electric tricycles are round tubes, so support bracket 4 is made of matching arc-shaped steel plate. If the supporting components are square tubes, support bracket 4 can be made of a matching right-angled U-shaped bracket.

[0040] The reinforcing ribs 5 are made of flat steel plates. The widths of the support rods 3, support brackets 4 and reinforcing ribs 5 are consistent. The distance between the two ends of the opening of the support bracket 4 is greater than the thickness of the support rod 3. A pair of reinforcing ribs 5 are symmetrically connected between the two ends of the opening of the support rod 3 and the support bracket 4.

[0041] A pair of moving wheels 7 are respectively mounted on both ends of the wheel arm 2 through a wheel axle, and the outer diameter of the moving wheel 7 is larger than the diameter of the wheel arm 2. A handle 6 is made of an arc-shaped steel plate and welded to the lever arm 1 so that the handle 6 can be easily held.

[0042] Please see the attached Figure 1 , the usage method and working principle of the utility model are:

[0043] The construction worker holds the handle 6 and lifts the lever 1, and can flexibly move the entire bracket through a pair of moving wheels 7, move the bracket to the side of the electric tricycle that needs to be repaired, and make the supporting bracket 4 located under the rod that needs to be supported on the electric tricycle.

[0044] The support bracket 4 is used to support the rods required to be supported on the electric tricycle. The pressure arm 1 is pressed down by the handle 6, and a pair of moving wheels 7 are used as fulcrums. The force arm 1 is used as a lever to rotate the support rod 3 to a vertical state, so that the support bracket 4 is synchronously rotated to the top of the support rod 3 vertically set, and the rods required to be supported on the electric tricycle are synchronously supported upward.

[0045] The lever arm 1 is pressed down to the ground, and the T-shaped structure formed by the lever arm 1 and the wheel arm 2 is placed on the ground, so that the bracket is erected with high stability, thereby safely and stably supporting the frame of the electric tricycle, making it easy to repair the electric tricycle.

[0046] After the maintenance is completed, it is only necessary to rotate the lever arm 1 upwards through the handle 6 to rotate the support rod 3 downwards synchronously, and then lower the frame of the electric tricycle and slowly land it on the ground.

[0047] During the process of supporting and lowering the frame of the electric tricycle, it is only necessary to hold the frame of the electric tricycle by hand to prevent it from deflecting and shaking. There is no need to manually lift the frame of the electric tricycle, and the operation is time-saving, labor-saving and safe.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
