Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile, especially a kind of automobile tailgate device. BACKGROUND

[0002] The automobile tailgate device is installed at the tail of the automobile to facilitate loading and unloading of goods. The existing automobile tailgate device mainly consists of a support, a tailgate and a driving member. The support is fixed to the girder at the tail of the automobile. The tailgate is rotatably connected to the support. The tailgate is vertically erected at the tail of the cargo compartment. When loading and unloading goods, the tailgate is driven downward by the driving member to abut the ground. The upper end surface of the tailgate is inclined downward. The goods slide along the upper end surface of the tailgate. The inclination angle of the tailgate is too large, which makes it difficult to push the goods upward into the cargo compartment during loading. Or the goods are easily damaged due to tilting during unloading, thereby affecting the loading and unloading efficiency and quality. SUMMARY

[0003] The utility model aims to solve at least one of the technical problems in the related art to some extent. Therefore, the utility model provides an automobile tailgate device, which can realize the lifting and tilting of the tailgate, thereby improving the loading and unloading efficiency and quality of goods.

[0004] According to the utility model embodiment, an automobile tailgate device is provided, which comprises a support, a tailgate, a lifting mechanism and a tilting mechanism. The support is provided with a mounting plate. The lifting mechanism comprises a connecting arm and a first driving member. Both ends of the connecting arm are rotatably connected to the support and the tailgate respectively. The fixed end of the first driving member is rotatably connected to the mounting plate. The telescopic end of the first driving member is rotatably connected to the connecting arm. The first driving member drives the connecting arm to rotate around one end of the connecting arm connected to the support through telescopic driving, so as to drive the tailgate to move up and down. The tilting mechanism comprises a second driving member. The fixed end of the second driving member is rotatably connected to the support. The telescopic end of the second driving member is rotatably connected to the tailgate.

[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 provided with mounting plate 110;Lifting mechanism 300 includes connecting arm 310 and first driving part 320, the both ends of connecting arm 310 are rotatably connected to support 100 and tailgate 200, the fixed end of first driving part 320 is rotatably connected to mounting plate 110, the telescopic end of first driving part 320 is rotatably connected to connecting arm 310, first driving part 320 drives connecting arm 310 around connecting arm 310 connecting the rotation of one end of support 100, 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 to support 100, the telescopic end of second driving part 410 is rotatably connected to tailgate 200, second driving part 410 drives tailgate 200 around connecting arm 310 connecting the rotation of one end of tailgate 200.

[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 unloading, the second driving member 410 is telescopically driven to rotate the tail plate 200 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 carrying of the goods onto the tail plate 200. Then, the first driving member 320 is telescopically driven to rotate the connecting arm 310 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, thereby adjusting the height position of the tail plate 200, and facilitating the carrying of the goods from the tail plate 200 to the ground. When loading, the goods are carried from the ground to the tail plate 200, and the first driving member 320 is telescopically driven to rotate the connecting arm 310 around one end of the connecting arm 310 connected to the support 100, so as to drive the tail plate 200 to move upward to the position of the vehicle compartment, thereby facilitating the carrying of the goods from the tail plate 200 to the vehicle compartment, and improving the loading and unloading efficiency and quality of the goods.

[0030] In addition, the first driving member 320 and the second driving member 410 are respectively driven to drive the tail plate 200 to move up and down and to turn over, so that the moving up and down and the turning over of the tail plate 200 can be independently performed, and the lifting position and the turning angle of the tail plate 200 are conveniently controlled.

[0031] When the first driving member 320 is telescopically driven to rotate the connecting arm 310 around one end of the connecting arm 310 connected to the support 100, so as to drive the tail plate 200 to move up and down, the tail plate 200 is always in the horizontal state, thereby reducing the possibility of goods falling during the lifting of the tail plate 200.

[0032] Secondly, the double driving members are used to drive the tail plate 200 to move up and down and to turn over, thereby reducing the structural complexity and the overall size and weight of the automobile tail plate device, and being suitable for small environmental protection vehicles and small trucks.

[0033] It should be noted that the telescopic end of the first driving member 320 can be rotatably connected to the middle segment of the connecting arm 310, so as to reduce the telescopic distance of the telescopic end of the first driving member 320, and to improve the overall load strength.

[0034] The first driving member 320 and the second driving member 410 can be air cylinders, hydraulic cylinders or electric push rods, and can be telescopically driven to rotate the connecting arm 310 and the tail plate 200.

[0035] 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 through the cross bar 330. The telescopic end of the first driving member 320 is rotationally connected to the cross bar 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 through the two connecting arms 310, which can disperse the stress, improve the overall structural strength, and improve the carrying strength. In addition, since the two connecting arms 310 are connected through the cross bar 330, the cross bar 330 is driven to move by the telescopic driving of the first driving member 320, so as to drive the connecting arms 310 on opposite sides to rotate synchronously around one end of the connecting arm 310 connected to the support 100, which can improve the stability of the lifting movement of the tail plate 200.

[0036] Specifically, referring to Figure 2 and Figure 3 , the telescopic end of the first driving member 320 is threadedly connected with a first rotating block 340, and the first rotating block 340 is rotationally connected to the cross bar 330. Since the telescopic end of the first driving member 320 is threadedly connected with the first rotating block 340, and the first rotating block 340 is rotationally connected to the cross bar 330, the telescopic end of the first driving member 320 can be detached from the cross bar 330 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.

[0037] It can be understood that, referring to Figures 1 to 5 , the bottom of the tail plate 200 is provided with a connecting seat 210, and the telescopic end of the second driving member 410 is rotationally connected to the connecting seat 210. By providing the connecting seat 210 at the bottom of the tail plate 200, and rotationally connecting the telescopic end of the second driving member 410 to the connecting seat 210, the telescopic end of the second driving member 410 can be driven to rotate the tail plate 200 from the bottom of the tail plate 200, and the connection between the telescopic end of the second driving member 410 and the tail plate 200 is staggered with the connection between the connecting arm 310 and the tail plate 200, so as to ensure the smoothness of the overturning of the tail plate 200.

[0038] In order to facilitate the carrying of goods between the tail plate 200 and the ground, when the tail plate 200 is lowered to a position close to the ground, the tail plate 200 is driven to rotate towards the ground by the second driving member 410, so that the upper end of the tail plate 200 is inclined downward in a direction away from the connecting arm 310 and abuts against the ground, thereby facilitating the loading and unloading of goods. However, the tail plate 200 is prone to collision and friction with the ground during rotation, which may cause damage to the tail plate 200.

[0039] Specifically, referring to Figure 3The turnover mechanism 400 further comprises a roller 420 rotatably connected to the connecting seat 210, and the roller 420 protrudes from the bottom of the connecting seat 210. Since the roller 420 protrudes from the bottom of the connecting seat 210, the tail plate 200 can be lowered to a position where the roller 420 abuts against the ground, and then the tail plate 200 is driven by the second driving member 410 to rotate towards the ground, the tail plate 200 rotates around the roller 420 as the fulcrum, which can improve the stability of the rotation of the tail plate 200, and at the same time, the roller 420 rolls along the ground to reduce the frictional resistance between the roller 420 and the ground, thereby improving the smoothness of the rotation of the tail plate 200.

[0040] It should be noted that an inclined surface 220 can be arranged on the bottom of the tail plate 200 away from the connecting arm 310, and the inclined surface 220 is inclined upward away from the connecting arm 310, so that the tail plate 200 is rotated to a position where the inclined surface 220 abuts against the ground, and the tail plate 200 is supported by the inclined surface 220 and the roller 420, which can improve the positional stability of the tail plate 200.

[0041] A plurality of reinforcing ribs 230 can be arranged on the bottom of the tail plate 200 in a longitudinal and transverse staggered manner, which can reduce the weight of the tail plate 200 while improving the structural strength of the tail plate 200, thereby improving the carrying capacity of the tail plate 200.

[0042] Specifically, referring to Figure 2 and Figure 3 , the turnover mechanism 400 further comprises a rotating shaft 430, and the second driving member 410 is rotatably connected to the connecting seat 210 through the rotating shaft 430, and the roller 420 is rotatably connected to the rotating shaft 430. Since the second driving member 410 is rotatably connected to the connecting seat 210 through the rotating shaft 430, the rotation stability of the second driving member 410 can be improved, and since the roller 420 is rotatably connected to the rotating shaft 430, the roller 420 and the second driving member 410 are located on the same axis, so that they can move synchronously, and since the roller 420 protrudes from the bottom of the connecting seat 210, the second driving member 410 is prevented from abutting against the ground by the roller 420, thereby reducing the possibility of the second driving member 410 colliding with the ground.

[0043] It can be understood that, referring to Figure 2 and Figure 3 , the second driving member 410 is threadedly connected with a second rotating block 440, and the second rotating block 440 is rotatably connected to the connecting seat 210. Since the second driving member 410 is threadedly connected with the second rotating block 440, and the second rotating block 440 is rotatably connected to the connecting seat 210, the second driving member 410 can be detached from the connecting seat 210 by rotating the second driving member 410, which facilitates the disassembly and maintenance of the second driving member 410.

[0044] It can be understood that, with reference to Figure 2 and Figure 3 , the fixed end of the first driving member 320 is provided with a first bolt 350, and the fixed end of the first driving member 320 is rotatably connected to the mounting plate 110 through the first bolt 350. Since the fixed end of the first driving member 320 is rotatably connected to the mounting plate 110 through the first bolt 350, by screwing the first bolt 350, the first bolt 350 is threaded out of the fixed end of the first driving member 320, so that the fixed end of the first driving member 320 can be detached from the mounting plate 110, thereby facilitating the disassembly and maintenance of the first driving member 320.

[0045] It can be understood that, with reference to Figure 2 and Figure 3 , the fixed end of the second driving member 410 is provided with a second bolt 450, and the fixed end of the second driving member 410 is rotatably connected to the support 100 through the second bolt 450. Since the fixed end of the second driving member 410 is rotatably connected to the support 100 through the second bolt 450, by screwing the second bolt 450, the second bolt 450 is threaded out of the fixed end of the second driving member 410, so that the fixed end of the second driving member 410 can be detached from the support 100, thereby facilitating the disassembly and maintenance of the second driving member 410.

[0046] It can be understood that, with reference to Figure 2 and Figure 3 , the 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 extension and retraction stability and high output force of the hydraulic cylinders are utilized to drive the tail plate 200 to lift and overturn, so that the stability of the tail plate 200 to lift and overturn and the carrying capacity of the tail plate 200 can be improved.

[0047] 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.
