Description

Technical Field

[0001] The utility model relates to the technical field of power battery structures, in particular to a structure capable of limiting the rotation of a protective cover of a power battery module. Background Art

[0002] At present, in the traditional design of the connection and assembly between the power battery module protective cover and the high-voltage support, the protective cover is in a free-rotating state when opened. Due to the effect of gravity, the protective cover will naturally fall down when opened, and needs to be reopened when operated again, as shown in technical solution 202322020315.X, which affects the efficiency of assembly and increases labor costs.

[0003] Due to the occurrence of this problem, in the existing assembly and connection process of the protective cover and the high-voltage support of the power battery module, most of them increase the contact area by increasing the rib position and the interference fit between the rotating movable column of the high-voltage support through the rotating movable column of the protective cover, thereby increasing the friction during closed use of the protective cover, so as to achieve the purpose that the protective cover will not fall off easily when it is opened during the production process. However, this method makes it difficult to accurately control the size of the increased contact area due to the interference fit during the production process, which occasionally leads to problems such as insufficient or non-standard interference fit, directly causing the scrapping of parts and further increasing costs. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a structure that can limit the rotation of the power battery module protective cover, so as to solve the problem in the prior art that the protective cover is in a state of free rotation when opened, affecting the efficiency of assembly and increasing labor costs, and the use of interference fit of a rotating moving column to increase the contact area, and the size of the contact area is difficult to accurately control during the production process, resulting in the scrapping of parts and the increase of costs.

[0005] The utility model provides a structure capable of limiting the rotation of a protective cover of a power battery module, comprising a protective cover, a base and a positioning assembly;

[0006] The protective cover is provided with a first assembly fixing area;

[0007] The base is provided with a second assembly fixing area, the second assembly fixing area is provided with an assembly hole, a first assembly groove and a first positioning groove, the first assembly groove is connected to the assembly hole, and the first positioning groove is arranged on one side of the assembly hole;

[0008] The positioning assembly includes a rotating column and a positioning extension. The rotating column is connected to the first assembly and fixing area of ​​the protective cover and can be rotatably inserted into the assembly hole of the second assembly and fixing area. The positioning extension is arranged on one side of the rotating column and is adapted to the first positioning groove.

[0009] Different from the prior art, the above technical solution has the following advantages: by setting the first positioning groove, the first positioning groove is adapted to the positioning extension piece of the Dong Wei assembly, and when the rotating column is rotated to the open state, it is convenient to rely on the extended positioning piece to be installed in the first positioning groove for positioning processing, thereby ensuring that the opening angle of the protective cover can be limited when it is opened, and avoiding the protective cover from always rotating freely in the assembly hole of the second assembly fixing area of ​​the base, thereby ensuring the assembly efficiency, and the overlapped and fixed structure only needs to be connected to the first assembly groove on one side to limit the angle, thereby avoiding the problem of component scrapping caused by the tolerance of the interference fit.

[0010] As a preferred embodiment of the present application, the number of the first positioning grooves is more than two, and the first positioning grooves are arranged around the assembly hole. By providing more than two first positioning grooves and surrounding the assembly hole, it is easy to achieve multi-angle positioning of the protective cover around the assembly hole, which is convenient for operators to select a specific opening angle.

[0011] As a preferred embodiment of the present application, the positioning extension is arranged on the first assembly fixing area on both sides of the protective cover. By arranging the positioning extension on the first assembly fixing area on both sides of the protective cover, it is convenient to perform positioning processing in both directions, thereby improving the fixing stability of the protective cover.

[0012] As a preferred embodiment of the present application, the first positioning groove is connected to the assembly hole. By setting the first positioning groove to be connected to the assembly hole, it is convenient to increase the adaptation tolerance of the first positioning groove and the positioning extension piece, thereby improving the assembly and use stability of the protective cover.

[0013] As a preferred embodiment of the present application, one end of the positioning extension piece is connected to the rotating column. By connecting one end of the positioning extension piece to the rotating column, it is convenient to increase the fixing area of ​​the positioning extension piece and the first positioning groove on the protective cover, and increase the stability of the open state fixation.

[0014] As a preferred embodiment of the present application, the second fixing area of ​​the base is connected to the base via an extension portion. By providing the extension portion, it is convenient to design the rotating column to be moved outward to avoid interference between the protective cover and the base.

[0015] As a preferred embodiment of the present application, the projection surface of the first positioning groove and the extension part do not overlap. By making the projection surface of the first positioning groove and the extension part not overlap, the first positioning groove is highlighted, and it is convenient for operators to observe whether the positioning extension piece reaches the first assembly groove. The extended structure facilitates the deformation of the second assembly fixing area, and facilitates the positioning extension piece to be separated from the first positioning groove during the closing process, thereby avoiding a large amount of structural damage and wear and tear, and improving the service life of the structure.

[0016] As a preferred embodiment of the present application, the first assembly groove is provided with a first assembly inclined surface. By providing the first assembly inclined surface of the first assembly groove, the guiding access of the rotating column is facilitated.

[0017] As a preferred embodiment of the present application, a second assembly slope is provided at the non-connecting end of the rotating column. By providing the second assembly slope at the non-connecting end of the rotating column, the revetment and the rotating column are connected to the assembly hole.

[0018] As a preferred embodiment of the present application, the depth of the first positioning groove is smaller than the depth of the assembly groove. By making the depth of the first positioning groove smaller than the depth of the assembly groove, it is convenient for operators to judge the access position and ensure the access effect of the first assembly groove.
