Detailed Description

In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

As shown in fig. 1 to 3, the deformation effect of the automatically deformable tailgate system changes the angle between the rear windshield and the trunk, which is specific to the three-compartment vehicle, into a negative angle through deformation, thereby achieving the effect of expanding the space.

Referring to fig. 3 to 9, the automatic deformation tailgate system includes a rear windshield 1 and a tailgate 2, the rear windshield 1 includes a first cross member 101, a side post 102, a first driving motor 103, a first hinge assembly 104, and a rear windshield glass 105, the first cross member 101 and the side post 102 enclose a quadrilateral first base frame, the rear windshield glass 105 and the first base frame are connected by welding, the first driving motor 103 is fixed on the lower side of the side post 102 by bolts, and the first driving motor 103 is fixed by bolts to the first hinge assembly 104. The first hinge assembly 104 includes a hinge 1041 and a hinge 1042, the first driving motor 103 is connected to the hinge 1042, the first driving motor 103 can drive the hinge 1042 to rotate, the hinge 1041 is fixed to a sheet metal bolt on the roof, the hinge 1042 is hinged to the hinge 1041, when the hinge is opened, the first driving motor drives the hinge 1042 to rotate, and the hinge drives the rear windshield 1 fixed to the hinge to rotate upward.

The trunk lid 2 includes a second cross member 201, a longitudinal member 202, a second drive motor 203, a second hinge assembly 204, and an upper cover plate 205. The second cross beam 201 and the longitudinal beam 202 form a quadrilateral second base frame, and the upper cover plate 206 and the second base frame are welded through welding connection. The second driving motor 203 is fixed on the lower side of the longitudinal beam 202 through bolts, an end bolt of the second driving motor 203 and the second hinge combination is fixed, the second driving motor 203 can drive the second hinge combination to rotate, and the other end of the second hinge rotation combination is fixed with a trunk sheet metal bolt. When the second hinge assembly 204 is opened, the second driving motor 203 drives one end of the second hinge assembly 204 to rotate, and the second hinge assembly 204 drives the trunk lid 2 fixed thereon to rotate upwards. The trunk lid 2 and the rear windshield 1 are rotatably connected by a locking lever 3.

As shown in fig. 3, after the back door is deformed, the side space 4 enclosed by the side pillars 102, the longitudinal beams 202 and the lower car body is sealed by using flexible leather and fabric, and the waterproof and windproof performance is satisfied.

Control buttons are arranged on a cab control panel and a vehicle key, the first driving motor 103 and the second driving motor 203 are connected, and deformation of the backdoor is controlled through the control motors.

And (3) deformation process: the control button sends out a deformation signal, the locking of the roof and the rear windshield, the locking of the rear windshield and the trunk lid, and the locking of the trunk lid and the back door lock are released, the first driving motor drives the rear windshield, the second driving motor drives the trunk lid to deform according to a deformation track, the roof and the rear windshield, the rear windshield and the trunk lid, and the trunk lid and the back door are locked, and the expansion is completed.

The invention is applied to three-box cars, the back door is of a lifting type, and the deformation of the back door can be realized by directly replacing the back door.

The folding mechanism can be hidden and folded, does not influence the driving of the vehicle and the wind resistance, has certain air tightness, does not leak rain or wind, and does not influence the visual field of a driver. When having big luggage article and need not put into the trunk, accessible trunk control button operation, the trunk can be automatic to be expanded, and increase trunk space also does not influence current trunk space when the deformation door is packed up.
