[0007] As a further technical solution of the present invention, a circular hole is provided at one end of the crooked bracket to cooperate with the hinge bolt of the tailgate hinge and be fixed by the bolt. The shape of the crooked bracket matches the curved surface of the top of the tailgate, and a gap is required at the top of the tailgate after installation.

[0008] The other end of the crutch also has a round hole, and the crossbar is fixed by bolts or quick-release bolts;

[0009] The knee brackets are used in pairs or in combination and are respectively installed on the hinge bolts of the tailgate hinge at different positions.

[0010] As a further technical solution of the present invention, the ladder is bolted or welded to the crossbar, and is vertical to the ground as a whole, with vertical pipes or vertical poles on the left and right sides and a horizontal pipe or beam in the middle;

[0011] The vertical tube of the ladder fits the overall curvature of the tailgate, and a gap is left to ensure space for fingers;

[0012] The ladder is welded close to the license plate or the license plate fixing frame is fixed with quick-release bolts, and the license plate is placed on the license plate fixing frame and fixed to the tailgate with the license plate bolts;

[0013] The ladder is centered or to one side relative to the tailgate;

[0014] The ladder also has a plurality of mounting holes for fixing other devices on the ladder.

[0015] As a further technical solution of the utility model,

[0016] After the ladder and the crossbar are fixed, there is a certain gap between them and the tailgate, and a buffer block is added at the gap to prevent the gap from becoming smaller;

[0017] The bottom area of ​​the buffer block is relatively large and is bonded to the tailgate. There is a protrusion on the top and a groove in the middle of the protrusion. The groove cooperates with the ladder and the crossbar. The height of the buffer block is slightly larger than the gap height.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The utility model relates to a lift-up door ladder, comprising a crank frame, a cross bar and a ladder. The crank frame is fixed to the hinge bolt of the tailgate hinge by a nut, which does not damage the door structure and is very firm. The cross bar is fixed to the crank frame by a nut. The ladder is also provided with a license plate fixing frame, which is fixed to the license plate hole of the car. The cross bar and the ladder are also provided with buffer blocks that fit the tailgate to prevent deformation during driving of the car. The ladder is also provided with fixing holes for fixing other devices and equipment.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0030] like Figures 1 to 4 As shown, a lift-up door ladder includes a crooked frame 1, a crossbar 2, and a ladder 3. The crooked frame 1 is fixed to the hinge bolts 7 of the tailgate hinge 5 by nuts 6. It is fixed at two positions on the left and right or fixed at multiple positions to increase strength. The tailgate hinge 5 at the rear of a normal car 10 is fixed by four bolts; the crossbar 2 is fixed to the crooked frame 1 by nuts 6. The ladder 3 also has a license plate fixing bracket 4 fixed to the license plate hole of the car 10.

[0031] like Figure 6 As shown, there are buffer blocks 8 on the crossbar 2 and the ladder 3.

[0032] like Figures 1 to 3 As shown, one end of the crooked bracket 1 has a circular hole that fits with the hinge bolt 7 of the tailgate hinge 5 and is fixed by a bolt 6. Its shape matches the curved surface of the top of the tailgate 9, and there should be a gap at the top of the tailgate 9 after installation.

[0033] The other end of the bending bracket 1 also has a circular hole, which is used to fix the cross bar 2 by bolts. Two or more bending brackets are used in combination and are respectively installed on the hinge bolts 7 of the tailgate hinge 5 at different positions.

[0034] like Figure 4 and Figure 5 As shown, the ladder 3 is fixed or welded to the crossbar 2 by bolts or quick-release bolts. When the tailgate 9 is closed, the ladder 3 is vertical to the ground as a whole and slightly tilted backward. There are vertical pipes or vertical poles on the left and right sides of the ladder 3 and a horizontal pipe or beam in the middle.

[0035] The vertical tube of the ladder 3 is in line with the overall curvature of the tailgate, especially the top has a larger curvature, and a gap is left between the ladder 3 and the tailgate 9 to ensure space for fingers.

[0036] like Figure 4As shown, the ladder 3 is welded or fastened with the license plate holder 4 by quick-release bolts close to the license plate, and the license plate is placed on the license plate holder 4 and fixed to the license plate mounting hole on the tailgate 9 by the license plate bolts;

[0037] The ladder is centered or to one side relative to the tailgate;

[0038] like Figure 5 As shown, the ladder also has multiple mounting holes for fixing other devices on the ladder.

[0039] like Figure 6 As shown, after the ladder 3 and the crossbar 2 are fixed, there is a certain gap between them and the tailgate 9, and the buffer block 8 is bonded at the gap to increase the fixing strength and prevent the gap from becoming smaller due to vibration and deformation displacement;

[0040] The bottom 8 of the buffer block has a large area and is bonded to the tailgate 9. There is a bulge on the top and a groove in the middle of the bulge. The groove cooperates with the ladder 3 and the cross bar 2. The height of the buffer block is slightly larger than the gap height. It can be compressed appropriately and the bonding position can be arranged at will according to the usage.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
