Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

A plurality of corbels 6 are detachably connected to the two cross frames 3 located on both sides, the positions of the corbels 6 can be set according to actual needs, and the corbels 6 are used to connect other components of the motor home such as mudguards and steps. The corbels 6 are slidingly connected to sliding rods 7, the sliding rods 7 are used for limiting and bearing, and the two ends of the sliding rods 7 are located between the two first longitudinal frames 2. A spare tire frame 8 is fixedly connected to the tail part of the frame body 1, the spare tire frame 8 comprises two triangle frames 9, the two triangle frames 9 are connected through a connecting rod 10, one connecting lug 11 is fixedly connected to each side of the triangle frame 9, the triangle frame 9 is bolted to two mounting frames 12 through the connecting lugs 11 on both sides, the two mounting frames 12 are fixedly connected to the two cross frames 3 located in the middle, and a stiffening rod 13 is fixedly connected between the first longitudinal frame 2 located at the tail side and the tail end of the two cross frames 3 located in the middle, and the stiffening rod 13 is used to improve the supporting force of the tail end of the cross frame 3.

[0023] The four ends of the cross support frames 5 are fixedly installed at the intersection of the cross frames 3 and the second longitudinal frames 4, the cross support frames 5 have three groups, one group located in the middle and two groups located on both sides are installed on the front and back of the frame body 1 respectively.

[0024] A plurality of first screw holes 14 are formed in the two cross frames 3, and a second screw hole is formed in one end of the bracket 6 and penetrates the upper and lower surfaces of the bracket 6. The first screw holes 14 have the same inner diameter as the second screw hole, and the first screw holes 14 and the second screw hole are used to detachably connect the bracket 6 to the cross frame 3 by means of the first screw.

[0025] A through hole is formed in the bracket 6 and penetrates the left and right sides of the bracket 6. The inner diameter of the through hole matches the diameter of the slide rod 7, and the bracket 6 is slidably connected to the slide rod 7 at the through hole.

[0026] A threaded hole is formed in the apex of the tripod 9, and a thread is formed in the two ends of the connecting rod 10 and matches the threaded hole. The connecting rod 10 is detachably connected to the tripod 9 at the thread.

[0027] The opposite sides of the two mounting frames 12 are smooth arc surfaces.
