[0034] See also Figure 1 and Figure 3 A foldable double-layer car transport rack is mainly used for ocean transportation of container ships, container flat-bottom bulk carriers, and road transportation. The car transport rack includes a bottom frame 1, end walls 2, an upper frame 3, a support rod 4, and a diagonal support rod 5. Both ends of the bottom frame 1 are hinged with end walls 2. Both ends of the upper frame 3 are detachably connected to the middle of the end walls 2 at both ends of the bottom frame 1. The bottom frame 1 and the upper frame 3 are used to support the car. The two ends of the upper frame 3 are installed in the middle of the end walls 2 at both ends of the bottom frame 1. The two end walls 2 can be used to support the two ends of the upper frame 3.

[0035] See also Figures 2 to 4 The lower end of the support rod 4 is hinged to the middle part of the bottom frame 1, a sleeve 41 is sleeved on the support rod 4, the sleeve 41 is hinged to the middle part of the upper frame 3, a plurality of first through holes 42 are opened on the support rod 4, and the upper and lower ends of the sleeve 41 are provided with stoppers 43, and the stoppers 43 are inserted into the first through holes 42 to fix the position of the sleeve 41; the support rod 4 supports the middle part of the upper frame 3, and the stoppers 43 are inserted into the first through holes 42 located at the upper and lower ends of the sleeve 41, and the two stoppers 43 limit the sleeve 41 to fix the sleeve 41, and the upper frame 3 is fixed at this time;

[0036] The lower end of the diagonal brace 5 is hinged to the bottom frame 1, and the upper end is detachably connected to the end wall 2. The diagonal brace 5 is used to support the end wall 2 and strengthen the connection between the bottom frame 1 and the end wall 2. By using the two end walls 2 to support the two ends of the upper frame 3, using the support rod 4 to support the middle of the upper frame 3, and using the diagonal brace 5 to strengthen the connection between the bottom frame 1 and the end wall 2, the supporting force of the upper frame 3 is effectively improved, so that the upper frame 3 can carry multiple cars. The bottom frame 1 is placed on a flat ground and can also carry multiple cars. Therefore, this car transport rack is suitable for the scene where multiple cars are placed on each floor. Fig.12 When the car transport rack is in use, two cars are placed on the upper layer and two cars are placed on the lower layer. In some other embodiments, the upper frame 3 and the bottom frame 1 can be provided with more placement positions, not limited to placing two cars on each layer. In addition, since the lower end of the diagonal brace 5 is hinged to the bottom frame 1 and the upper end is detachably connected to the end wall 2, after the upper end of the diagonal brace 5 is disassembled from the end wall 2, the diagonal brace 5 can be folded on the bottom frame 1.

[0037] Since the lower end of the support rod 4 is hinged to the middle of the bottom frame 1, a sleeve 41 is sleeved on the support rod 4, and the sleeve 41 is hinged to the middle of the upper frame 3. After the upper frame 3 is disassembled from the end wall 2 and the stopper 43 is pulled out, the upper frame 3 can slide down along the support rod 4 to the lower end of the support rod 4 through the sleeve 41. At this time, the upper frame 3 is placed on the top surface of the bottom frame 1, and the lower end of the support rod 4 is hinged to the bottom frame 1, so that the support rod 4 can be laid on the bottom frame 1. In addition, after the upper end of the diagonal support rod 5 is disassembled from the end wall 2, the diagonal support rod 5 can be folded on the bottom frame 1, the end wall 2 is hinged to the bottom frame 1, and the end wall 2 can also be folded. Therefore, see Fig.11 When the automobile transport rack is idle, firstly, the upper rack 3 is suspended by a sling and then the two ends of the upper rack 3 are disassembled from the two end walls 2; then, the limit piece 43 is pulled out to allow the sleeve 41 to slide, so as to facilitate the lifting and lowering of the upper rack 3; then, the upper rack 3 is lowered to the top surface of the base frame 1 by the sling, and the support rod 4 is laid down on the base frame 1; finally, the upper end of the diagonal support rod 5 is disassembled from the end wall 2, the diagonal support rod 5 is folded and laid down on the base frame 1, and the end wall 2 is folded and laid down on the base frame 1, so that the entire automobile transport rack is folded, thereby saving the occupied space when the transport rack is idle.

[0038] In this embodiment, support rods 4 are provided on both the front and rear sides of the upper frame 3, which has a stronger supporting effect than that provided on one side; in addition, when the lengths of the upper frame 3 and the bottom frame 1 are long, it is possible to consider providing multiple support rods 4 in the length direction of the bottom frame 1 to support the upper frame 3, so as to further improve the supporting effect on the upper frame 3. In this embodiment, the diagonal support rods 5 are located at the corners of the bottom frame 1, and one diagonal support rod 5 is provided at each corner, with a total of four diagonal support rods 5, which support the front and rear sides of the two end walls 2.
