The moving directions of the first lock rod 7 and the second lock rod 8 are perpendicular to the moving direction of the top pressure switch 3, the first lock rod 7 and the second lock rod 8 are on the same straight line, after the first lock rod 7 and the second lock rod 8 are inserted into the lock holes on the outer decorative plate, the outer decorative plate can be locked and fixed on the mounting framework 13. After the first lock rod 7 and the second lock rod 8 are moved out of the lock holes on the outer decorative plate, the outer decorative plate can be disassembled from the mounting framework 13.

[0026] As shown in the drawings, Figure 3 and Figure 4 The first spring 4 is arranged between the top pressure switch 3 and the inner plate 2, the first spring 4 is a cylindrical helical spring and is a compression spring, the first spring 4 is used for exerting an elastic force on the top pressure switch 3 to move it to a position away from the first reversing rod 5 and the second reversing rod 6, so as to realize the reset of the top pressure switch 3.

[0027] As shown in the drawings, Figure 3 and Figure 4 The second spring 9 is arranged between the first lock rod 7 and the inner plate 2, the second spring 9 is a cylindrical helical spring and is a compression spring, the second spring 9 is used for exerting an elastic force on the first lock rod 7 to move it to insert into the lock hole of the outer decorative plate. The third spring 10 is arranged between the second lock rod 8 and the inner plate 2, the third spring 10 is a cylindrical helical spring and is a compression spring, the third spring 10 is used for exerting an elastic force on the second lock rod 8 to move it to insert into the other lock hole of the outer decorative plate.

[0028] As shown in the drawings, Figure 3 and Figure 4 One end of the first reversing rod 5 is in contact with the top pressure switch 3, the other end of the first reversing rod 5 is in contact with the end of the first reversing rod 5, the first reversing rod 5 is rotatably connected to the inner plate 2 at a position between the two ends, when the first reversing rod 5 rotates, it can push the first reversing rod 5 to move linearly on the inner plate 2, and the second spring 9 is compressed.

[0029] As shown in the drawings, Figures 1 to 4As shown, the mounting frame 13 is equipped with multiple buffer blocks for contact with the exterior trim panel. The main function of the buffer blocks is to cushion the exterior trim panel when it is closed, absorbing the impact and vibration that may be generated during the closing process.

[0030] like Figures 1 to 4 As shown, in this embodiment, two buffer blocks are provided, and the two buffer blocks are respectively installed at opposite ends of the mounting frame 13. The two buffer blocks are the first buffer block 11 and the second buffer block 12.

[0031] When the top pressure switch 3 at the bottom of the exterior trim panel is pressed, the first locking rod 7 and the second locking rod 8 move towards each other. The first locking rod 7 and the second locking rod 8 move out of the lock hole on the exterior trim panel. After the exterior trim panel is rotated at a specific angle, it can be disassembled from the mounting frame 13 in a specific direction, thereby realizing the disassembly of the exterior trim panel from the mounting frame 13.

[0032] like Figures 1 to 4 As shown, a fixed shaft is provided on the mounting frame 13. The outer trim panel has mounting holes for inserting the fixed shaft and notches for passing through it; the notches communicate with the mounting holes. Two fixed shafts are provided, with two mounting holes at each end of the outer trim panel along its length. The two fixed shafts are inserted into the two mounting holes respectively. The notches on the outer trim panel are through holes extending from the outer surface of the trim panel towards the mounting holes, allowing the fixed shafts to pass through during trim panel assembly and disassembly. The fixed shafts have a flat structure, and their outer surfaces include two parallel planes and two oppositely arranged arc surfaces. The two arc surfaces are coaxial, with the two planes parallel to the axes of the two arc surfaces. The axes of the two arc surfaces are located between the two planes, and the ends of the two planes connect to the ends of the arc surfaces along their arc length. The thickness of the fixed shaft (the distance between the two planes) is less than the width of the notch, and the diameter of the arc surfaces is greater than the width of the notch. When the outer trim panel is rotated until one arc surface of the fixed shaft aligns with the notch, the outer trim panel can be removed from the mounting frame 13, allowing the fixed shafts to pass through the notches. When the exterior trim panel is closed, the arc surface of the fixed shaft is offset from the notch.

[0033] The specific motion principle of the locking mechanism is as follows: the top-pressure switch 3 is positioned on the inner plate 2 through the guide groove and constrained to slide along the Z direction on the inner plate 2; the first spring 4 is positioned between the inner plate 2 and the top-pressure switch 3 through the limiting boss to provide a holding force to ensure the gap between the top-pressure switch 3 and the outer trim panel; the first reversing rod 5 and the second reversing rod 6 are respectively mounted on the rotating shaft on the inner plate 2, and their function is to convert the Z-direction transmission force of the top-pressure switch 3 into the Y-direction transmission force required by the first locking rod 7 and the second locking rod 8; the first locking rod 7 and the second locking rod 8 are respectively positioned on the inner plate 2 through the limiting groove at a specific angle and constrained to slide along the Y direction on the inner plate 2.

[0034] When the maintenance cover is in the closed state, the first lock rod 7 and the second lock rod 8 are respectively inserted into the corresponding lock holes of the mounting frame 13; the second spring 9 is positioned between the inner plate 2 and the first lock rod 7 through the limiting boss to provide the required holding force for the cooperation of the lock rod and the lock hole, and the corresponding second lock rod 8 and the inner plate 22 are also designed with the third spring 10 to provide the holding force.

[0035] Compared with the traditional buckle clamping or bolt screwing scheme, the front engine compartment maintenance cover assembly has the advantages of easy disassembly, aesthetic appearance, etc.; compared with the traditional pull wire lock or PUSH lock structure scheme, the front engine compartment maintenance cover assembly has the advantages of low cost, light structure, small space ratio, etc.

[0036] The utility model further provides a vehicle, including above-mentioned structure's front engine compartment maintenance cover assembly. The front engine compartment maintenance cover assembly can refer to Figures 1 to 4 , and will not be repeated here. Since the vehicle of the utility model includes the front engine compartment maintenance cover assembly in the above embodiment, it has all the advantages of the above-mentioned front engine compartment maintenance cover assembly.

[0037] The utility model is exemplarily described above in combination with the drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned mode. As long as various non-essential improvements are carried out by adopting the method concept and technical scheme of the utility model; or without improvement, the above-mentioned concept and technical scheme of the utility model are directly applied to other occasions, which are all within the protection scope of the utility model.
