[0026] The tailgate escape cover of the present invention will be further described below in conjunction with specific embodiments to help those skilled in the art to have a more complete, accurate and in-depth understanding of the technical solution of the present invention.

[0027] Example 1

[0028] like Figure 3-10 As shown, the back door escape cover of this embodiment includes a back door lower trim 100, an escape cover 200, a rotating shaft 300, a spring 400, a spring 500 and a switch group 600. The back door lower trim 100 is provided with an escape opening 110, and the first hook seat 120 and the second hook seat 130 are provided on both sides of the upper edge of the escape opening 110. The first hook seat 120 includes a first fixing seat and a first U-shaped hook, and the second hook seat 130 includes a second fixing seat and a second U-shaped hook. The first fixing seat and the second fixing seat are located on the back door lower trim 100, and the first U-shaped hook and the second U-shaped hook are located above the escape opening 110. A slot structure is provided on the first U-shaped hook. A lock tongue seat 150 is provided at the lower end of the escape opening 110. The first rotating shaft mounting structure 220 and the second rotating shaft mounting structure 230 are provided on both sides of the upper end of the escape cover 200. A door-shaped groove structure 210 is disposed in the middle of the escape cover plate 200 , and a locking tongue 250 is disposed in the lower portion of the escape cover plate 200 .

[0029] The switch group 600 is arranged on the bolt seat 150, the first end of the spring 400 is fixedly engaged with the door-shaped groove structure 210 of the escape cover 200, and the second end of the spring 400 is fixedly engaged with the groove structure on the first U-shaped hook. The escape cover 200 matches the lower tailgate trim 100 and makes the first rotating shaft mounting structure 220 and the second rotating shaft mounting structure 230 located between the first hook seat 120 and the second hook seat 130, the first rotating shaft mounting structure 220 and the first hook seat 120 are adjacent, and the second rotating shaft mounting structure 230 and the second hook seat 130 are adjacent. The open end of the rotating shaft 300 passes through the first U-shaped hook, the first rotating shaft mounting structure 220, the spring 400, the second rotating shaft mounting structure 230 and the second U-shaped hook in sequence to rotatably connect the lower tailgate trim 100 and the escape cover 200, and the bolt 250 cooperates with the switch group 600. The spring sheet 500 is arranged between the open end of the rotating shaft 300 and the second hook seat 130 to fix the axial direction of the rotating shaft 300. The locking tongue 250 cooperates with the switch group 600 to control the locking and opening of the escape cover 200. When the switch group 600 is pressed, the position switch is in the open state. Under the action of the spring 300, the escape cover 200 automatically opens around the rotating shaft 300. When the switch group 600 is pressed again, the position switch is in the locked state and the escape cover 200 is closed.

[0030] This embodiment is improved on the basis of the existing structure. A rotating shaft structure is arranged at the upper edge of the rear door lower trim panel where the escape cover plate matches. The escape cover plate and the rear door lower trim panel are respectively designed with their own injection molding structures to be connected and fixed to the rotating shaft. A combination switch is arranged at the center of the lower edge of the rear door lower trim panel where the escape cover plate matches to control the locking and opening of the escape cover plate. This solves the problems of small disassembly opening of the rear door escape cover plate, destructive opening, and difficulty in opening the escape cover plate by hand.

[0031] For ordinary technicians in this field, the specific embodiments are only illustrative descriptions of the utility model. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, they are all within the protection scope of the utility model.
