[0022] Refer to Figure 1-7 , a roof guard frame that can self-adjust the distance to adapt to different wheelbase frames, includes a front assembly and a rear assembly. The front assembly is butt-jointed and fixed with the rear assembly. The design meets the structural integrity of the roof guard frame, has high strength, does not damage the original strength of the roof guard frame, and the opening of the roof guard frame considers the mainstream lifting method for battery replacement, making it more practical;

[0023] The front assembly includes a left front leg 1 and a right front leg 2. An instrument rack assembly 3, a front plate 5 and a first rectangular steel pipe 6 are fixed between the left front leg 1 and the right front leg 2. A first L-shaped connecting block 9 is fixed at the top of the left front leg 1. A second rectangular steel pipe 7 is fixed on the surface of the first L-shaped connecting block 9. One end of the second rectangular steel pipe 7 far from the first L-shaped connecting block 9 is fixed with a second L-shaped connecting block 10. When installing the left front leg 1 and the right front leg 2 of the roof guard frame, the three-degree inclination welding method is more in line with the aesthetic needs of people;

[0024] The rear assembly includes a left rear leg 13 and a right rear leg 14. Special-shaped telescopic frames 15 are fixed at the tops of the left rear leg 13 and the right rear leg 14.
