The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

A kind of folding tailgate device of the utility model; As shown in Figure 1, it comprises tailgate panel 1, connects support 2, bearing 3, hoist cylinder 4, connecting rod 5, and tailgate panel 1 front end is with to be connected support 2 rear ends hinged; It is hinged to connect support 2 front ends and bearing 3; Bearing 3 captive joint automobile tails, an end of hoist cylinder 4 support 2 rear ends that are articulated and connected, the other end hinged support 3 of hoist cylinder 4.When hoist cylinder 4 stretches, connect support 2 around connecting the jointed shaft rotation of support 2 with bearing 3, tailgate panel 1 up-and-down movement.Connecting rod 5 front end hinged supports 3; Hinged tailgate panel 1 front end in connecting rod 5 rear ends, tailgate panel 1 can turn to forward and connect support 2 tops, have reduced taking up room of this folding tailgate device; The utility model can place in the automobile tail below; Its scientific structure is simple, and it is little to take up room, applicable to multiple vehicle.

Like Fig. 7, shown in Figure 8, tailgate panel 1 is provided with torsion spring 11, and torsion spring 11 is arranged at tailgate panel 1 and the hinged place that is connected support 2, and is more laborsaving when torsion spring 11 can make upset tailgate panel 1.

Further, like Fig. 7, shown in Figure 8, the rear end of tailgate panel 1 is hinged with extension plate 6; Extension plate 6 can be around the jointed shaft rotation of tailgate panel 1 with extension plate 6; When extension plate 6 rotated to maximum angle backward, tailgate panel 1 was concordant with the upper surface of extension plate 6, at this moment; Tailgate panel 1 constitutes objective table together with extension plate 6, has enlarged cargo area.

As shown in Figure 7, tailgate panel 1 is provided with anti-skidding lines with extension plate 6 upper surfaces, can increase the friction force of tailgate panel 1 and extension plate 6 upper surfaces, prevents that article or people from sliding.

The hoist cylinder 4 of the utility model is two, and two hoist cylinders 4 laterally arrange, and it is more steady that this folding tailgate device is gone up and down, and rotating torque is bigger, can hold up heavier article.

The connecting rod 5 of the utility model is two, and two connecting rods 5 laterally arrange, and can make tailgate panel 1 upset of this folding tailgate device more steady.

Can be installed on the different automobiles for the ease of this folding tailgate device, bearing 3 connects automobile tail through connecting device 7, and the size of connecting device 7 is adjusted according to automotive type.Particularly, as shown in Figure 1, connecting device 7 comprises connecting panel 71, crossbeam 72, adapter plate 73, and bearing 3 passes through bolted connection connecting panel 71, connecting panel 71 captive joint crossbeams 72, and crossbeam 72 is through adapter plate 73 captive joint automobile tails.The folding tailgate device of the utility model can be installed easily, dismantle.

The principle of work of the utility model:

As shown in Figure 1, the tailgate panel of this folding tailgate device 1 holds up to the compartment with extension plate 6, can be easily with the article carrying in the compartment to tailgate panel 1, extension plate 6, and also can be to the compartment with the article carrying on tailgate panel 1, the extension plate 6.

As shown in Figure 2, tailgate panel 1 descends: the piston rod of hoist cylinder 4 shrinks, and tailgate panel 1 moves downward, and in motion process the maintenance level.

Like Fig. 3, shown in Figure 4, upset extension plate 6: extension plate 6 can manually overturn forward, makes extension plate 6 be captured in tailgate panel 1 top.

As shown in Figure 5; Turn on the tailgate panel 1: the piston rod elongation of overturning oil cylinder 5; Tailgate panel 1 rotates forward with the jointed shaft that is connected support 2 around tailgate panel 1, is captured in to connect support 2 tops, and extension plate 6 is with 1 upset of tailgate panel; At this moment, tailgate panel 1, extension plate 6 all are positioned at the automobile tail below.

As shown in Figure 6, the tailgate panel rises: elongation hoist cylinder 4, hoist cylinder 4 drives and connects support 2, tailgate panel 1, extension plate 6 upward movements, makes tailgate panel 1, extension plate 6 near the automobile tail lower end.

Said process is the process that places of the folding tailgate device of the utility model, otherwise, can it be stretched from the automobile bottom, be used to load and unload article.

Like Fig. 1, shown in Figure 2, successively bonded assembly tailgate panel 1, connect support 2, bearing 3, connecting rod 5 and constitute parallelogram sturcutres, so during tailgate panel 1 loading and unloading article, tailgate panel 1 can keep level, does not overturn.

Should be noted that at last; Above embodiment is only in order to explain the technical scheme of the utility model; But not to the restriction of the utility model protection domain, although with reference to preferred embodiment the utility model has been done explanation at length, those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement the technical scheme of the utility model, and not break away from the essence and the scope of the utility model technical scheme.
