A welding fixture is welded to the front part of the upper surface of the vehicle body. An adjusting foot is provided in the inner frame part of the welding fixture. Arc grooves are opened on the outer walls of both sides of the welding fixture. A connecting rod is slidably connected to the groove opening. An adjusting handle and a rotating cap are respectively installed at both ends of the connecting rod. The connecting rod is hinged to the adjusting handle.

[0007] As a further embodiment of this utility model: the front and rear parts of the arc groove are provided with grooves, and the grooves are concave.

[0008] As a further embodiment of this utility model: a vertical cylinder is welded to the front end of the adjusting foot, a support plate is welded to the bottom of the vertical cylinder, a damping spring is installed on the lower surface of the support plate, and a top rod is installed on the top of the vertical cylinder.

[0009] As a further embodiment of this utility model: a second connecting rod is provided below the first connecting rod, and the second connecting rod is fixedly connected to the inner frame of the welding fixture.

[0010] As a further improvement of this utility model: a through hole is provided on the lower part of the outer wall of the adjusting foot, and a connecting rod 2 is provided at the cavity of the through hole, and the diameter of the cavity of the through hole is larger than the radius of the connecting rod 2.

[0011] As a further improvement of this utility model, the number of welding fixtures is two sets, and both sets of welding fixtures are in a semi-arc support shape.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this utility model, an arc groove inside the welding fixture is used for the sliding of connecting rod one. By loosening the adjusting handle, connecting rod one can slide at the opening of the arc groove. When connecting rod one slides to the groove, the vertical cylinder will be tilted onto the vehicle board. When connecting rod one slides to another set of grooves, as shown in Figure 3, the vertical cylinder is perpendicular to the vehicle board. Connecting rod two, installed between the two sets of welding fixtures, is used to cooperate with the through hole opened on the lower part of the outer wall of the adjusting foot, so that the vertical cylinder will not shift after tilting towards the vehicle board. Its structure is more optimized and its design is more reasonable. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4. In this embodiment of the present invention, a foldable electric vehicle frame includes a vehicle plate 1, a support leg 9 hinged to the side of the vehicle plate 1, a rear plate 7 fixedly connected to the rear part of the upper surface of the vehicle plate 1, and a damping spring 8 installed at the rear drive wheel part of the vehicle plate 1. A welding fixture 2 is welded to the front part of the upper surface of the vehicle plate 1. An adjusting foot 10 is provided in the inner frame part of the welding fixture 2. Arc grooves 11 are opened on the outer walls of the left and right sides of the welding fixture 2. A connecting rod 14 is slidably connected to the groove opening of the arc groove 11. An adjusting handle 13 and a rotating cap 15 are respectively installed at both ends of the connecting rod 14. The connecting rod 14 and the adjusting handle 13 are hinged together.

[0021] The front and rear parts of the groove 11 are provided with grooves 12, which are concave.

[0022] A vertical cylinder 4 is welded to the front end of the adjusting foot 10, a support plate 3 is welded to the bottom of the vertical cylinder 4, a damping spring 6 is installed on the lower surface of the support plate 3, and a top rod 5 is installed on the top of the vertical cylinder 4.

[0023] A second connecting rod 16 is provided below the first connecting rod 14, and the second connecting rod 16 is fixedly connected to the inner frame of the welding fixture 2.

[0024] A through hole 17 is provided on the lower part of the outer wall of the adjusting foot 10. A connecting rod 16 is provided at the cavity opening of the through hole 17, and the diameter of the cavity opening of the through hole 17 is larger than the radius of the connecting rod 16.

[0025] There are two sets of welding fixtures 2, and both sets of welding fixtures 2 are in a semi-arc support shape.

[0026] The working principle of this utility model is as follows:
