[0044] At the same time, the present invention can achieve rigid installation and fixation of the exterior cover plate 2 by using the fixed locking block 9 and the sliding locking block 51, avoiding the problem of the exterior cover plate 2 being prone to sagging when connected with a traditional hinge structure.

[0045] In the present invention, the mounting structure is the basic frame portion of the inspection cover assembly, which is used to support and fix the entire inspection cover assembly.

[0046] The mounting structure mainly includes a cover plate bracket 1, which provides a mounting base for the exterior cover plate 2. In the present invention, the cover plate bracket 1 is connected to the vehicle body frame through fasteners, such as bolts.

[0047] In the present invention, the exterior cover plate 2 is the outer covering part of the inspection cover plate assembly, which is mainly used to cover the components inside the vehicle to play a protective and aesthetic role.

[0048] It is also convenient for the subsequent opening to facilitate the inspection, maintenance and replacement of parts in the front cabin area of the vehicle, and it is also convenient for the refilling of windshield washer fluid, etc.

[0049] In addition, in the present invention, the fixing structure is a key part connecting the mounting structure and the exterior cover plate 2, which is used to ensure that the exterior cover plate 2 is firmly fixed to the mounting structure and can achieve reliable opening and closing functions.

[0050] The locking mechanism 5 is a core component of the fixed structure, and its design directly determines the reliability and operational convenience of the inspection cover.

[0051] The locking mechanism 5 includes the following two key components:

[0052] The fixed locking block 9 is installed on the cover bracket 1 to play the role of fixing and positioning.

[0053] The sliding locking block 51 is connected to the exterior cover plate 2 and can cooperate with the fixed locking block 9 to achieve locking and unlocking functions.

[0054] In the present invention, the sliding locking block 51 can slide, and the exterior cover plate 2 is locked by combining the sliding locking block 51 with the fixed locking block 9, and the exterior cover plate 2 is unlocked by separating the sliding locking block 51 from the fixed locking block 9.

[0055] How it works

[0056] Locked state: When the sliding locking block 51 is hooked on the fixed locking block 9, the exterior cover 2 is firmly fixed on the cover bracket 1 to ensure that it will not loosen during the driving of the vehicle.

[0057] Unlocked state: By operating the sliding locking block 51 to disengage it from the fixed locking block 9, the exterior cover 2 can be opened to facilitate inspection or maintenance of the vehicle interior.

[0058] The cooperation between the fixed locking block 9 and the sliding locking block 51 simplifies the complex locking structure of the traditional inspection cover.

[0059] The hooking method of the sliding locking block 51 and the fixed locking block 9 is simple and reliable, and can effectively prevent the exterior cover plate 2 from loosening during the driving of the vehicle.

[0060] The operation of the sliding locking block 51 is simple and intuitive, and the user can easily open and close the inspection cover.

[0061] This design reduces the number and complexity of parts, thereby reducing manufacturing costs.

[0062] Furthermore, the mounting structure in the present invention further includes a crossbeam 3 on the cover plate; in the present invention, the crossbeam 3 on the cover plate acts as a connecting member and also acts as an exterior decorative member.

[0064] In the present invention, the cross beam 3 on the cover plate is a part of the mounting structure and is connected to the cover plate bracket 1 .

[0065] The main function of the crossbeam 3 on the cover is to provide additional support and fixing points to enhance the structural strength and stability of the entire inspection cover assembly; at the same time, it can realize the plug-in fixation of the upper end of the exterior cover 2.

[0066] In the present invention, the plug-in mechanism is an important component of the fixing structure, which is used to further ensure a firm connection between the exterior cover plate 2 and the mounting structure.

[0067] In the present invention, the plug-in mechanism includes a bracket plug-in slot 33 and a cover plate latch 6 .

[0068] The bracket insertion slot 33 is provided on the cover plate cross beam 3 for receiving the cover plate latch 6 .

[0069] The cover plate latch 6 is provided on the exterior cover plate 2 and is used to cooperate with the bracket insertion slot 33 .
