Referring to fig. 6C, 7A and 7B, in the case that the width W of the tailgate, the length L2 of the rack body 1, the rotation axis 021 of the tailgate, the vertical axis 11 of the rack body 1 (i.e., the rotation axis of the rack body 1) and the distance L1 and the horizontal included angle α between the rotation axis 021 of the tailgate and the vertical axis 11 are determined, the opening degree of the tailgate 02 depends on the distance L3 between the central axis of the positioning slider 41 and the U-shaped bottom of the U-shaped mounting plate 42 in the rack mounting structure 4 and the distance L4 between the central axis of the rack mounting structure 4 and the end of the tailgate 02, and the opening degree of the tailgate 02 is not less than 90 ° by properly designing the sizes of L3 and L4. Referring to fig. 6C and 7B, as can be seen from the movement trajectories of the end of the tail gate 01, the end of the rack body 1 and the central axis of the rack mounting structure 4, the intersection point of the end of the rack body 1 and the horizontal line is B, the intersection point of the central axis of the rack mounting structure 4 and the horizontal line is a, the intersection point of the end of the tail gate 02 and the horizontal line is C, in the horizontal direction (i.e., the closed state of the tail gate 02) and the fully opened state of the tail gate 02, the mounting position of the rack mounting structure 4 on the tail gate 02 is constrained by the stroke of the positioning slider 41, i.e., L4 is at least greater than the distance between B, C, and the closer the rack mounting structure 4 is to the end of the tail gate, the larger the opening degree of the tail gate 02 is until the end of the tail gate 02 butts against the rack body 1; the greater the distance L3 between the center axis of the positioning slider 41 and the U-shaped bottom of the U-shaped mounting plate 42, the greater the opening degree of the tailgate 02.
In another embodiment, a handle 5 is arranged at one end part of the bracket body 1 far away from the vertical shaft 11, when the tail door 02 is opened, the tail door 02 can be opened by pulling the handle 5, and the spare tire bracket moves along with the tail door 02. It is obvious that the handle arranged on the tail gate 02 itself can be pulled to open the tail gate.
It should be noted that the present invention is not limited to the specific technical solutions disclosed in the above embodiments, and the technical concept of the present invention can still be realized through simple deformation or component replacement, for example, the appearance of the support body 1 can be changed at will, and only the installation of the spare tire installation structure 3 and the installation of the positioning sliding shaft 14 need to be ensured, or the shapes and the sizes of the support body 1 and the support installation structure 4 need to be adjusted, only the slidable and rotatable matching relationship between the positioning slider 41 and the positioning sliding shaft 14 needs to be ensured, and the shape and the installation relationship of the positioning slider 41 are not limited.
