The escape cover has a rotating shaft structure on each side of its upper edge, and a hook structure on each side of its lower edge. A recessed circular hole mounting structure is located at the center of the lower end of the escape cover. The rear door lower trim panel has a square groove structure that matches the rotating shaft structure, and the rotating shaft structure and the square groove structure cooperate with each other. Double-sided locking structures are located on both sides of the lower end of the rear door lower trim panel, and the hook structure engages and is fixed to the double-sided locking structure. An opening knob with a locking tongue structure is located at the center of the lower end of the escape cover. The opening knob is mounted on the recessed circular hole mounting structure and can rotate around the axis of the recessed circular hole mounting structure. A square hole locking groove structure is located on the rear door lower trim panel, and the locking tongue structure cooperates with the square hole locking groove structure to control the locking and unlocking of the escape cover.

[0005] The opening knob is provided with a protruding structure, and the recessed circular hole mounting structure of the escape cover is provided with a limiting groove structure; the protruding structure and the limiting groove structure cooperate with each other to control the rotation stroke of the opening knob.

[0006] The limiting groove structure has two parts.

[0007] The rotating shaft structure and the escape cover are integrally injection molded structures.

[0008] The square groove structure has a circular arc feature.

[0009] Compared with the prior art, the flip-open rear hatch escape cover assembly of this utility model has the following advantages:

[0010] This invention features self-injected rotating shaft structures on both sides of the upper edge of the escape cover, allowing the escape cover to flip and open around the rotating shaft. A knob structure is also added to control the locking and unlocking of the escape cover. At the same time, hooks that meet the disassembly requirements are used to fix the escape cover, solving the problems of small disassembly openings for the rear door escape cover, destructive opening, and difficulty in opening the escape cover by hand.

[0021] The following will further elaborate on the flip-open rear hatch escape cover assembly of this utility model with reference to specific embodiments, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the technical solution of this utility model.

[0022] Example 1

[0023] like Figure 3-8As shown, the flip-open rear door escape cover assembly of this embodiment includes a rear door lower trim panel 100, an escape cover 200, and an opening knob 300. The upper end of the escape cover 200 flips open around a rotation axis, and the lower end is fixed to the rear door lower trim panel 100 by a snap-fit ​​structure that meets disassembly requirements. The opening knob controls the locking and unlocking of the escape cover. Specifically, the upper edge of the escape cover 200 has integrally injection-molded rotation axis structures 210 on both sides, the lower edge of the escape cover 200 has snap-fit ​​structures 220 on both sides that meet disassembly requirements, and the lower center of the escape cover 200 has a recessed round hole mounting structure 230. The rear door lower trim panel 100 is provided with a square groove structure 110 with arc-shaped features that matches the rotation axis structure. The rotation axis structure 210 and the square groove structure 110 with arc-shaped features cooperate with each other, so that the escape cover 200 can be flipped open around the rotation axis. The lower rear door trim panel 100 has double-sided locking structures 120 on both sides of its lower end. The hook structure 220 of the escape cover 200 is interlocked and fixed with the double-sided locking structures 120 of the lower rear door trim panel 100, ensuring the hook structures are not damaged during the opening of the escape cover. An opening knob 300 with a locking tongue is arranged at the center of the lower end of the escape cover 200. The opening knob 300 is mounted on the recessed circular hole mounting structure 230 and can rotate around the axis of the recessed circular hole mounting structure 230. The opening knob 300 has a protruding point structure, and the recessed circular hole mounting structure 230 of the escape cover 200 has two limiting groove structures. The protruding point structure and the limiting groove structure cooperate to control the rotation stroke of the opening knob 300. Figure 9-10 As shown, the opening knob 300 is designed with a locking tongue structure, and the lower trim panel 100 of the rear door is provided with a square hole locking groove structure 130. The locking tongue structure and the square hole locking groove structure 130 cooperate with each other to control the locking and unlocking of the escape cover 200. The flip-open rear door escape cover assembly of this embodiment is designed with a rotating shaft and a square groove structure. The upper part of the escape cover flips around the rotating shaft, opening in a flip-open manner, which solves the problem of difficult opening of the escape cover. The opening knob is designed to control the locking of the escape cover, which solves the problem of small opening for disassembly and difficulty in opening the escape cover by hand. The lower end of the escape cover is provided with a snap-fit ​​structure that meets the disassembly requirements and is fixed to the lower trim panel of the rear door, which solves the problem of destructive opening of the escape cover and reduces costs.

[0024] For those skilled in the art, the specific embodiments are merely exemplary descriptions of the present invention. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention are within the protection scope of the present invention.
