[0028] It can be understood that, with reference to Figures 1 to 5 The utility model discloses a kind of automobile tailgate devices, including support 100, tailgate 200, lifting mechanism 300 and turnover mechanism 400, support 100 is rotatably connected with rotating support 110, rotating support 110 can abut support 100, to limit rotating support 110 rotates to the direction close to support 100;The bottom of tailgate 200 is provided with connecting seat 210, connecting seat 210 is rotatably connected with roller 220, roller 220 protrudes from the bottom of connecting seat 210;Lifting mechanism 300 includes connecting arm 310 and first driving part 320, both ends of connecting arm 310 are rotatably connected in rotating support 110 and tailgate 200, the fixed end of first driving part 320 is rotatably connected in rotating support 110, the telescopic end of first driving part 320 is rotatably connected in connecting arm 310, first driving part 320 drives connecting arm 310 to rotate around the one end of connecting arm 310 connecting rotating support 110 by telescopic, to drive tailgate 200 to lift and move;Turnover mechanism 400 includes second driving part 410, the fixed end of second driving part 410 is rotatably connected in support 100, the telescopic end of second driving part 410 is rotatably connected in connecting seat 210, second driving part 410 drives tailgate 200 to rotate around the one end of connecting arm 310 connecting tailgate 200 by telescopic.

[0029] The support 100 is fixedly installed on the beam at the rear of the automobile, and the tail plate 200 is vertically erected at the rear of the vehicle compartment. When loading and unloading the goods, the second driving member 410 is driven to extend and retract to drive the tail plate 200 to rotate around one end of the connecting arm 310 connected to the tail plate 200, so that the tail plate 200 is turned from the vertical state to the horizontal state, thereby facilitating the loading of the goods onto the tail plate 200. Then the first driving member 320 is driven to extend and retract to drive the connecting arm 310 to rotate around one end of the connecting arm 310 connected to the support 100, so as to drive the tail plate 200 to move downward to the ground. Since the rollers 220 protrude from the bottom of the connecting seat 210, the rollers 220 first abut against the ground to reduce the possibility of damage to the first driving member 320, the second driving member 410 and the tail plate 200 due to collision with the ground, thereby prolonging the service life. Then the first driving member 320 drives the tail plate 200 to continue to move downward, the rollers 220 are driven to rotate the rotating bracket 110 in the direction away from the support 100 due to the force of the ground, and the rollers 220 roll along the ground to lift the tail plate 200, and at the same time, the tail plate 200 is rotated and inclined around one end of the connecting arm 310 connected to the tail plate 200 in the direction of the ground until the tail plate 200 abuts against the ground, so that an angle is formed between the tail plate 200 and the ground, which facilitates loading and unloading of the goods onto the tail plate 200, thereby improving the loading and unloading efficiency and quality.

[0030] After loading and unloading the goods from the ground, the first driving member 320 is driven to extend and retract to drive the connecting arm 310 to rotate around one end of the connecting arm 310 connected to the support 100, so as to drive the tail plate 200 to move upward. At the same time, the rotating bracket 110 is rotated in the direction close to the support 100 due to the action of gravity until it abuts against the support 100 to limit the rotation of the rotating bracket 110, so that the tail plate 200 returns to the horizontal state. Then the first driving member 320 drives the tail plate 200 to move upward to the position of the vehicle compartment. Since the tail plate 200 is in the horizontal state during the lifting process, the possibility of the goods falling over and falling off can be reduced, thereby improving the stability of loading and unloading the goods.

[0031] In addition, the connecting arm 310 and the first driving member 320 are synchronously moved by the rotating bracket 110 to replace the balance oil cylinder to adjust the angular position of the tail plate 200, which can reduce the complexity of the structure and reduce the overall volume and weight of the automobile tail plate device.

[0032] It should be noted that the first driving member 320 and the second driving member 410 can be air cylinders or electric push rods, etc., which can drive the connecting arm 310 or the tail plate 200 to rotate by extension and retraction.

[0033] A slope 230 can be arranged at the bottom of the tail plate 200 away from the side of the connecting arm 310, the slope 230 is inclined upward away from the connecting arm 310, so that the tail plate 200 is rotated to the position where the slope 230 is attached to the ground in the direction close to the ground, and the tail plate 200 is supported by the cooperation of the slope 230 and the roller 220, which can improve the position stability of the tail plate 200.

[0034] A plurality of reinforcing ribs 240 can be arranged at the bottom of the tail plate 200, which can reduce the weight of the tail plate 200 while improving the structural strength of the tail plate 200, so as to improve the carrying capacity of the tail plate 200.

[0035] It can be understood that, with reference to Figures 2 to 5 , the support 100 is provided with a limiting plate 120, and the rotating support 110 can abut against the limiting plate 120 to limit the rotating support 110 from rotating in the direction close to the support 100. After loading and unloading the goods from the ground, the connecting arm 310 is driven to rotate around the one end of the connecting arm 310 connected to the support 100 by the first driving member 320, so as to drive the tail plate 200 to move upward, and at the same time, the rotating support 110 is rotated in the direction close to the support 100 due to gravity, until it abuts against the limiting plate 120 to limit the rotating support 110 from rotating in the direction close to the support 100, so that the tail plate 200 returns to the horizontal state, thereby improving the stability of loading and unloading the goods.

[0036] Specifically, with reference to Figure 5 , the limiting plate 120 is provided with a vertically extending sliding hole 121, and the sliding hole 121 is provided with a positioning bolt 130, the positioning bolt 130 is threadedly connected to the rotating support 110, and the nut of the positioning bolt 130 can abut against the side of the limiting plate 120 away from the rotating support 110 to limit the rotating support 110 from rotating in the direction away from the support 100. Since the limiting plate 120 is provided with the vertically extending sliding hole 121, and the sliding hole 121 is provided with the positioning bolt 130, the positioning bolt 130 is threadedly connected to the rotating support 110, when the rotating support 110 rotates in the direction away from the support 100, the positioning bolt 130 moves with the rotating support 110 and slides vertically upward along the sliding hole 121, until the nut of the positioning bolt 130 abuts against the side of the limiting plate 120 away from the rotating support 110 to limit the rotating support 110 from rotating in the direction away from the support 100, which can position the rotating position of the rotating support 110, so as to reduce the possibility of the tail plate 200 being damaged due to excessive inclination, thereby improving the stability of the tail plate 200 rotating and inclining to the ground.

[0037] It can be understood that, with reference to Figure 2 and Figure 3The two connecting arms 310 are symmetrically arranged on opposite sides of the tail plate 200, and the two connecting arms 310 are connected by the cross rod 330. Since the two connecting arms 310 are symmetrically arranged on opposite sides of the tail plate 200, the support 100 and the tail plate 200 are connected from opposite sides of the tail plate 200 by the two connecting arms 310, and the two connecting arms 310 are connected by the cross rod 330, so that the stress can be dispersed to improve the overall structural strength, thereby improving the carrying strength. In addition, since the two connecting arms 310 are connected by the cross rod 330, the synchronism of the rotation of the two connecting arms 310 can be improved to improve the stability of the lifting movement of the tail plate 200.

[0038] It can be understood that, referring to Figures 2 to 4 The telescopic end of the first driving member 320 is threadedly connected with a first rotating block 321, and the first rotating block 321 is rotationally connected to the connecting arm 310. Since the telescopic end of the first driving member 320 is threadedly connected with the first rotating block 321, and the first rotating block 321 is rotationally connected to the connecting arm 310, the telescopic end of the first driving member 320 can be detached from the connecting arm 310 by rotating the telescopic end of the first driving member 320, so as to facilitate the disassembly and maintenance of the first driving member 320.

[0039] It can be understood that, referring to Figures 2 to 4 The telescopic end of the second driving member 410 is threadedly connected with a second rotating block 411, and the second rotating block 411 is rotationally connected to the connecting seat 210. Since the telescopic end of the second driving member 410 is threadedly connected with the second rotating block 411, and the second rotating block 411 is rotationally connected to the connecting seat 210, the telescopic end of the second driving member 410 can be detached from the connecting seat 210 by rotating the telescopic end of the second driving member 410, so as to facilitate the disassembly and maintenance of the second driving member 410.

[0040] It can be understood that, referring to Figure 3 The turnover mechanism 400 further comprises a rotating shaft 420, the telescopic end of the second driving member 410 is rotationally connected to the connecting seat 210 through the rotating shaft 420, and the roller 220 is rotationally connected to the rotating shaft 420. Since the telescopic end of the second driving member 410 is rotationally connected to the connecting seat 210 through the rotating shaft 420, the rotation stability of the telescopic end of the second driving member 410 can be improved, and since the roller 220 is rotationally connected to the rotating shaft 420, the roller 220 and the telescopic end of the second driving member 410 are located at the same axial position, so that they can move synchronously. In addition, since the roller 220 protrudes from the bottom of the connecting seat 210, the telescopic end of the second driving member 410 is limited from abutting against the ground by abutting against the ground through the roller 220, so that the possibility of the telescopic end of the second driving member 410 colliding with the ground can be reduced.

[0041] It can be understood that, referring to Figure 3The first driving member 320 and the second driving member 410 are both hydraulic cylinders. Since the first driving member 320 and the second driving member 410 are both hydraulic cylinders, the stability of the lifting and overturning of the tail plate 200 and the carrying capacity of the tail plate 200 can be improved by using the stability of extension and contraction and high output force of the hydraulic cylinders.

[0042] It can be understood that, referring to Figure 2 and Figure 3 , the lifting mechanism 300 is arranged in two groups, and the two groups of lifting mechanisms 300 are symmetrically arranged on opposite sides of the support 100. The stability of the lifting movement of the tail plate 200 and the carrying capacity of the tail plate 200 can be improved by driving the tail plate 200 to lift and move from opposite sides of the support 100 through the two groups of lifting mechanisms 300.

[0043] It can be understood that, referring to Figure 2 and Figure 3 , the overturning mechanism 400 is arranged in two groups, and the two groups of overturning mechanisms 400 are symmetrically arranged on opposite sides of the support 100. The stability of the overturning of the tail plate 200 and the carrying capacity of the tail plate 200 can be improved by driving the tail plate 200 to overturn from opposite sides of the support 100 through the two groups of overturning mechanisms 400.

[0044] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by those skilled in the art without departing from the purpose of the utility model.
