[0002] A car tailgate, also known as a car lift tailgate, car loading and unloading tailgate, lifting tailgate, hydraulic car tailgate, or truck tailgate, is a hydraulic lifting and loading / unloading device powered by the vehicle's battery, installed at the rear of trucks and various vehicles. Car tailgates can be classified as: cantilever tailgates, vertical tailgates, rocker arm tailgates, and folding tailgates. As a vehicle loading and unloading tool, the tailgate can greatly improve the efficiency and convenience of loading and unloading, and is widely used in aerospace, military, fire protection, postal, financial, petrochemical, commercial, food, pharmaceutical, environmental protection, logistics, manufacturing and other industries.

[0003] Chinese Patent Announcement CN216508075U discloses an automatic lifting tailgate structure for automobiles. Its key technical features include: a mounting box and a lifting mechanism; the mounting box has symmetrically arranged columns on its upper left side, with mounting brackets slidably connected to the upper ends of both columns, and rotating holes at the lower ends of both mounting brackets rotatably connected to the rotating shaft at the right end of the tailgate; the lifting mechanism is located inside the mounting box, with its upper end threadedly connected to threaded holes corresponding to the rear ends of the two mounting brackets; baffles are provided at the openings at both the front and rear ends of the mounting box, and the front and rear ends of the lifting mechanism are rotatably connected to through holes in the middle of the baffles on the same side; wherein, fixing holes are evenly distributed on the right end of the mounting box.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0029] like Figures 1 to 4As shown, a vertical lifting high-strength composite material tailgate includes two sliding vertical beams 1, a connecting crossbeam 2 between the two sliding vertical beams 1, a flipping base 3 on each of the two sliding vertical beams 1, a tailgate 4 rotatably connected to each of the flipping bases 3, a flipping assembly for driving the tailgate 4 to flip on each of the two sliding vertical beams 1, a composite plate 19 between the two tailgates 4, a transition plate 5 at the end of each of the two tailgates 4, a compensation plate 6 on each of the two transition plates 5 for compensating for the height difference on the ground, and two sets of rotating assemblies for driving the compensation plate 6 to rotate on the compensation plate 6.

[0030] Two sets of rotating components are connected to two transition plates 5 respectively. Two sliding vertical beams 1 and connecting crossbeams 2 form a stable support structure. The compensation plate 6 should be a single long plate with two sets of rotating components connected to both ends. Through the corresponding connection between the sliding vertical beam 1 and the vehicle body, the sliding vertical beam 1 can drive the whole to move up and down accordingly. The sliding vertical beam 1 can be driven by a motor or cylinder, etc. This part is relatively existing, so it will not be described in detail. The tail plate 4 is driven by the flipping component to flip accordingly, so that the goods can easily enter the transition plate 5 and the tail plate 4, and then enter the carriage. The transition plate 5 can form a slope with the ground, so that the goods can be pushed onto the tail plate 4 with less effort. However, the angle of the transition plate 5 is relatively fixed. On some ground, pushing the goods may cause swaying due to the height difference. At this time, the compensation plate 6 forms a corresponding angle with the ground to provide support, so that the transition plate 5 will not sway or deviate.

[0031] A flipping arm 7 is rotatably connected to the flipping base 3, and one end of the flipping arm 7 away from the flipping base 3 is connected to the tail plate 4; the flipping assembly includes an electric push rod 8, the fixed end of the electric push rod 8 is rotatably connected to the sliding vertical beam 1 through a shaft pin, and the electrically driven telescopic end is rotatably connected to a flipping seat 9, which is fixedly connected to the side wall of the flipping arm 7.

[0032] The flip base 3 provides support for the flip arm 7, enabling the flip arm 7 to drive the tail plate 4 to flip. The electric push rod 8 is the driving source. The electric push rod 8 drives the tail plate 4 to flip accordingly through the flip arm 7. The electric push rods 8 at both ends simultaneously drive the tail plate 4 to flip accordingly.

[0033] The rotating assembly includes a rotating top plate 10 disposed at the bottom of the compensation plate 6, a driving assembly disposed on the rotating top plate 10, and a rotating base plate 12 slidably connected to the bottom of the rotating top plate 10 via two rotating slides 11. The two ends of the rotating base plate 12 are provided with slide grooves 13 for the rotating slides 11 to slide. One side of the rotating base plate 12 is bolted to the inner wall of the transition plate 5. The driving assembly includes a rotating worm gear 14 disposed on the rotating top plate 10, the rotating worm gear 14 passing through the bottom of the rotating top plate 10, the rotating worm gear 14 meshing with a rotating worm wheel 15, the rotating worm gear 14 being disposed on the rotating base plate 12, and a rotating motor 16 being drivenly connected to the rotating worm gear 14. The rotating motor 16 is bolted to the rotating top plate 10 via a rotating seat 17.

[0034] The rotating slide 11 slides within the slide groove 13. Through its fixed connection with the rotating top plate 10, it can drive the rotating top plate 10 to rotate accordingly. The rotating motor 16 is the power source and can drive the rotating worm 14 to rotate through its output shaft. The rotating worm 14 meshes with the rotating worm wheel 15, driving the rotating top plate 10 to rotate. It also has a self-locking function, allowing the compensation plate 6 to form a corresponding angle with the ground, compensating for the height difference between the transition plate 5 and the ground. The transition plate 5 and the tail plate 4 will not wobble or shift.

[0035] Two sliding vertical beams 1 are provided with locking seats 18 on the top of the side facing the tail plate 4; the tail plate 4 is locked in place by the locking seats 18, providing a force so that the tail plate 4 will not flip due to the shaking of the vehicle body during the driving process, causing the cargo to spill out.

[0036] The composite panel 19 includes an intermediate layer 20, which is specifically a continuous fiber reinforced thermoplastic honeycomb panel. An upper aluminum alloy plate 21 is bonded to the upper surface of the intermediate layer 20, and a lower aluminum alloy plate 22 is bonded to its lower surface.

[0037] The thickness of the intermediate layer 20 is 30-40mm, the thickness of the upper aluminum alloy plate 21 is 1.5-3mm, and the thickness of the lower aluminum alloy plate 22 is 1-3mm; the surface of the upper aluminum alloy plate 21 is provided with wear-resistant patterns.

[0038] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
