[0029] Please refer to Figure 1 and Figure 2 To solve the above technical problems, the utility model provides a kind of vehicle rear wheel fixing device, including fixed frame 31, rear wheel fixing part 32 and rear wheel turnover part 33 are installed in the fixed frame 31;
[0030] The fixed frame 31 is provided with accommodating cavity 311, and the accommodating cavity 311 is used to install the rear wheel fixing part 32 and the rear wheel turnover part 33;The rear wheel fixing part 32 is fixedly arranged at the front end of the fixed frame 31, and the rear wheel turnover part 33 is rotatably arranged at the rear end of the fixed frame 31;The rear wheel turnover part 33 is turned back and forth towards the direction of the rear wheel fixing part 32, and the rear wheel fixing part 32 and the rear wheel turnover part 33 form a rear wheel containing groove 34 for fixing the rear wheel of the vehicle, and the rear wheel containing groove 34 is arranged sunken relative to the upper surface of the fixed frame 31.
[0031] By arranging the rear wheel fixing part 32 and the rear wheel turnover part 33 on the fixed frame 31, the rear wheel containing groove 34 for fixing the rear wheel is formed between the rear wheel fixing part 32 and the rear wheel turnover part 33, and the rear wheel containing groove 34 is arranged sunken relative to the upper surface of the fixed frame 31. When parking the vehicle, the rear wheel of the vehicle is placed in the rear wheel containing groove 34, and the rear wheel of the vehicle presses the rear wheel turnover part 33 under the action of its own weight, and the rear wheel fixing part 32 fixes the front part of the rear wheel. At this time, the front and rear ends of the rear wheel respectively abut against the rear wheel fixing part 32 and the rear wheel turnover part 33, so as to lock the rear wheel in the rear wheel containing groove 34. The rear wheel of the vehicle can be fixed, and the parking stability of the rear wheel is improved. The problem that the rear wheel of the existing vehicle cannot be fixed and the parking stability is poor can be solved.
[0032] Please refer to Figure 1 and Figure 2Further, the rear wheel fixing part 32 comprises a front baffle 321 in the accommodating cavity 311.
[0033] The lower end of the front baffle 321 is fixedly connected to the bottom of the fixed frame 31, the upper end of the front baffle 321 is fixedly connected to the upper end surface of the fixed frame 31, and the front baffle 321 is inclined upward away from the rear wheel turnover part 33.
[0034] By setting the upwardly inclined front baffle 321, when the rear wheel enters the rear wheel accommodating groove 34, the outer peripheral wall of the rear wheel can be tangent to the plane of the front baffle 321, which can increase the contact area of the rear wheel and the front baffle 321, and help to tightly press the rear wheel on the front baffle 321.

[0036] Preferably, the left and right sides of the front baffle 321 are respectively and symmetrically connected with the side baffles 322, and the distance between the two side baffles 322 gradually increases from the front baffle 321 to the horizontal direction of the rear wheel turnover part 33. By setting the side baffles 322, and gradually increasing the distance between the two side baffles 322 from the front baffle 321 to the direction of the rear wheel turnover part 33, it is helpful to fix wheels of different size specifications between the two side baffles 322.
[0037] Please refer to Figures 1 to 3 Further, the rear wheel turnover part 33 comprises a first turnover part 331, a second turnover part 332 and a first pivot part 333.
[0038] The first turnover part 331 comprises a first turnover bottom plate 3311, the second turnover part 332 comprises a second turnover bottom plate 3321, and the first turnover bottom plate 3311 and the second turnover bottom plate 3321 are connected in a V shape.
