Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric vehicle technology, and in particular to an anti-reverse connection structure for the side cover and top cover of a vehicle body, and an electric vehicle. Background Technology
[0002] Currently, the exterior components of electric vehicles are mainly plastic parts, including side covers, top covers, and rear covers. The side covers are typically assembled with the top and rear covers using snap-fit and / or screw connections. Different exterior components have different shapes, and the location and number of snap-fit and screw mounting points also vary. For some connection areas, snap-fit and screw connections are usually placed adjacent to each other to prevent the top cover from detaching from the side cover (i.e., preventing it from coming off). However, for some vehicle models, the exterior components have special shapes. Due to space constraints at the connection points, adjacent connection points cannot be placed in the same location, causing a technical problem where deformation and gaps can easily occur under stress. Utility Model Content

[0034] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0035] See Figures 1 to 4 The anti-retraction connection structure of the vehicle body side cover and top cover in this embodiment includes a side cover 2 and a top cover 1. The bottom two sides of the top cover 1 are provided with a plurality of first docking positions, which are distributed at intervals along the length of the vehicle body. The upper side of the side cover 2 is provided with a plurality of second docking positions corresponding to the first docking positions. The first docking positions are used to cooperate with the second docking positions to limit the upper cover 1 and the side cover 2 to move up and down, that is, to prevent the top cover 1 from moving up or the side cover 2 from moving down.
[0036] The first docking position includes a figure-eight hook 3, and the second docking position includes a retaining rib 7 and a positioning groove 21; or, the first docking position includes a retaining rib 7 and a positioning groove 21, and the second docking position includes a figure-eight hook 3.
[0037] At least one of the seven-shaped hooks 3 has a mounting hole 4;
[0038] On the side cover 2 or the top cover 1, a first threaded connection position 6 is provided in the area corresponding to the position of the hook 3 with the mounting hole 4. It is used to align with the mounting hole 4 and lock it with the locking member to limit the left and right movement of the top cover 1 and the side cover 2, that is, to prevent the two from separating in the horizontal direction, thereby eliminating the gap at the connection.
[0039] Specifically, the locking element can be a self-tapping screw.
[0040] Specifically, both the side cover 2 and the top cover 1 are plastic parts.
[0041] As a preferred method, such as Figure 5 As shown, the structure of the figure-eight hook 3 includes a main body 31 and a bent portion 32 that bends to one side from the main body 31. Specifically, the main body 31 and the bent portion 32 form a figure-eight shape. After the figure-eight hook 3 is assembled with the positioning groove 21, the main body 31 is limited by the positioning groove 21, while the bent portion 32 extends to one side after extending out of the positioning groove 21. A first wedging surface 321 for wedging with the retaining rib 7 is formed on the upper side of the bent portion 32. The mounting hole 4 is provided on the bent portion 32.
[0042] It is understandable that, for ease of fitting, the width of the main body 31 is limited by the positioning groove 21, and the length of the positioning groove 21 is greater than the length of the main body 31.
[0043] It is understandable that the wedge-shaped clamp 7 and the figure-eight hook 3 are tightly fitted together by elastic deformation and compression. As a preferred method, such as... Figure 8 As shown, the retaining rib 7 is strip-shaped, and its bottom surface has a second wedge-tightening surface 701 that fits vertically with the first wedge-tightening surface 321.
[0044] In this embodiment, the top cover and side cover can be quickly positioned during installation via the positioning groove. The interlocking ribs and the figure-eight hooks provide initial vertical restraint. However, traditional figure-eight hooks only provide vertical restraint. Because the positioning groove is longer than the main body, the top cover and side cover are not fully locked together, requiring additional screws or self-tapping screws for horizontal fastening. This embodiment cleverly places at least one fastening point on the bend of the figure-eight hook. At this location, multiple functions are achieved: positioning of the top cover and side cover (positioning groove and figure-eight hook), vertical restraint between them (figure-eight hook and interlocking rib), and horizontal fastening (mounting hole and first threaded connection). This improves space utilization and effectively reduces the number of individually installed threaded connections, making it suitable for compact vehicle models with high space requirements.
[0045] As a preferred embodiment, the bent portion 32 extends toward the rear of the vehicle body.
[0046] As a preferred embodiment, the first mating position is a figure-eight hook 3, and the second mating position is a retaining rib 7 and a positioning groove 21. Several figure-eight hooks 3 are arranged at intervals along the bottom of the upper cover 1, and a mounting hole 4 is provided on one of the figure-eight hooks 3 at the end. This end is preferably the end closest to the rear of the vehicle body.
[0047] As a preferred embodiment, a second threaded connection position 5 is provided at the other end of the side cover 2 and the top cover 1, away from the hook 3 with the mounting hole 4.
[0048] See Figure 6 and Figure 7 As a preferred embodiment, the upper side of the side cover 2 is provided with an L-shaped edge, which includes a horizontal edge 22 extending horizontally inward from the body of the side cover 2 and a vertical edge 23 extending vertically upward from the horizontal edge 22. The positioning groove 21 is provided on the horizontal edge 22. The retaining rib 7 is provided on the inner side of the horizontal edge 22.
[0049] As a preferred embodiment, the body of the top cover 1 is integrally formed with the first mating position, and the body of the side cover 2 is integrally formed with the second mating position.
[0050] This embodiment also provides an electric vehicle, including the aforementioned anti-reverse connection structure between the side cover and the top cover of the vehicle body.
[0051] For ease of observation, Figure 1 Only the connection structure between one side cover and the top cover is shown. Those skilled in the art will understand that during actual assembly, the left and right side covers are symmetrically connected to the left and right sides of the lower part of the top cover with the same structure.
[0052] It will be understood by those skilled in the art that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
