DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 6 The utility model provides the following technical solutions: a shared electric vehicle frame, including an electric vehicle frame 1, a mounting plate 2 is installed at one end of the electric vehicle frame 1, a support column 3 is fixed by bolts on the inner side of the mounting plate 2, an adjusting rotating rod 4 is rotatably connected inside the support column 3, a positioning hole 7 is opened on the outer side of the adjusting rotating rod 4, an end of the adjusting rotating rod 4 extending out of the support column 3 is connected to a support frame 5, and an auxiliary wheel 6 is rotatably connected to the end of the support frame 5; a positioning rod 9 is elastically connected to the side of the support column 3 through a first spring 8, and the positioning rod 9 and the positioning hole 7 are engaged with each other;

[0028] Furthermore, the support frame 5 forms a rotating structure with the support column 3 by adjusting the rotating rod 4. The support frame 5 is symmetrically arranged about the longitudinal center line of the electric frame 1, and the angle of the support frame 5 can be flexibly adjusted, so as to realize the retraction and extension of the auxiliary wheel 6; the position of the positioning hole 7 corresponds to the position of the positioning rod 9, and the center lines of the two positioning holes 7 are perpendicular to each other. After the angle of the support frame 5 is adjusted by 90°, the positioning rod 9 can be inserted into the positioning hole 7 at the corresponding position to limit the adjusting rotating rod 4 and the support frame 5;

[0029] When it rains, snows, and freezes in winter, the positioning rod 9 can be pulled, and the positioning rod 9 stretches and stores force on the first spring 8, and the positioning rod 9 is moved out of the positioning hole 7, and the positioning of the adjusting rotating rod 4 is released, and the support frame 5 can be moved to rotate downward through the adjusting rotating rod 4, and rotated 90°. At this time, the auxiliary wheel 6 contacts the ground, and the positioning rod 9 is released. The first spring 8 can control the positioning rod 9 to be stuck in the positioning hole 7 at the corresponding position, and the adjusting rotating rod 4 is locked to stabilize the position of the auxiliary wheel 6. The symmetrically distributed auxiliary wheels 6 are used to improve the stability of the electric vehicle frame 1 and ensure its smooth walking;

[0030] Furthermore, an enclosure outer frame 10 and a mounting frame 11 are installed on the inner side of the electric frame 1. The mounting frame 11 is arranged on the inner side of the enclosure outer frame 10. The corners of the mounting frame 11 are elastically connected with an adjusting rod 17 through a second spring 16. One end of the adjusting rod 17 extending into the mounting frame 11 is connected with a reinforcing plate 18. A through groove 12 is provided on the side of the mounting frame 11. A support plate 14 is slidably connected to the inner side of the mounting frame 11. A moving rod 13 is connected to the side of the support plate 14. A protrusion 15 is connected to the end of the moving rod 13.

[0031] Specifically, the enclosure outer frame 10 is a "U"-shaped structure, and there is a gap between the enclosure outer frame 10 and the protrusion 15. The enclosure outer frame 10 is used to enclose the structure at the installation frame 11 to ensure its smooth operation and prevent the frame crossbeam structure from blocking its operation; one end of the moving rod 13 is a bent structure, and the moving rod 13 passes through the through groove 12 and can slide in the through groove 12. The moving rod 13 can be used to support and limit the support plate 14 to ensure its vertical movement, and it can smoothly drive the moving rod 13 to drive the protrusion 15 to move and push the adjustment rod 17; the protrusion 15 is a trapezoidal structure, and the contact between the protrusion 15 and the adjustment rod 17 is a smooth structure, which can reduce the friction between the protrusion 15 and the adjustment rod 17 and gradually push the adjustment rod 17 to move;

[0032] When the battery is placed in the installation frame 11, the gravity of the battery itself will press the support plate 14 downward, and the support plate 14 moves downward in the installation frame 11. At this time, the moving rod 13 installed at the corner of the support plate 14 slides in the through groove 12 to ensure the vertical downward movement of the support plate 14. At the same time, the moving rod 13 controls the protrusion 15 installed at the end to move downward, and the protrusion 15 pushes the fitting adjustment rod 17 to move. The adjustment rod 17 squeezes and accumulates the second spring 16. At the same time, the adjustment rod 17 controls the reinforcement plate 18 installed at the end to move in the direction of fitting the corner of the battery, and squeezes and fixes the battery at four corners, so that the battery is firmly positioned in the installation frame 11 to prevent the battery from shaking. When the battery is taken out, the pressure on the support plate 14 is released. At this time, the second spring 16 can control the adjustment rod 17 to reset and move, and push the protrusion 15 to move up and reset, thereby controlling the moving rod 13 to drive the support plate 14 to move up and reset for subsequent use.
