Technical Field
[0001] This utility model relates to the field of new energy technology, and in particular to a battery box for new energy vehicles. Background Technology
[0002] In the field of new energy vehicle battery boxes, with the market's increasing sensitivity to product lightweighting, compactness, and cost, the hinge structure, as a core component connecting the upper and lower shells of the battery box, has made the optimization of its manufacturing process a key direction for industry technological upgrading. Traditional battery box hinges mostly adopt a shell-hole structure design, that is, the shaft hole structure is formed by an integral mold to achieve rotation. However, this type of design suffers from problems such as complex mold structure manufacturing, long manufacturing cycle, and relatively high manufacturing cost. Therefore, it is necessary to propose further solutions to these problems. Utility Model Content
[0003] The purpose of this utility model is to provide a battery box to overcome the shortcomings of the existing technology.
[0004] To achieve the above-mentioned utility model objectives, this utility model provides a battery box, which includes: an upper cover and a lower shell; the upper cover is connected to the opening of the lower shell through at least one set of pivoting structures;
[0005] The pivoting structure includes: a first pivot hinge, a second pivot hinge, and a third pivot hinge; the second pivot hinge and the third pivot hinge are spaced apart, and the second pivot hinge is pivotally engaged between the second pivot hinge and the third pivot hinge; the first pivot hinge, the second pivot hinge, and the third pivot hinge are coaxially connected by a pivot shaft.
[0006] As an improvement to the battery box of this utility model, the pivoting structure is configured as two sets, and the two sets of pivoting structures are arranged alternately between the upper cover and the opening.

[0020] The present invention will now be described in detail with reference to various embodiments. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.
[0021] like Figure 1-3 As shown, one embodiment of this utility model provides a battery box. In this embodiment, the battery box includes an upper cover 10 and a lower shell 20; the upper cover 10 is connected to the opening of the lower shell 20 through at least one set of pivoting structures 30. The pivoting structure 30 is changed to a structure in which the upper and lower shells 20 each have separate hinges, forming a complete shaft hole after docking. This avoids the need for complex mechanisms such as machining deep holes or side core pulling on the mold. This significantly reduces the design and processing difficulty of the mold.
[0022] Specifically, the pivot structure 30 of this embodiment includes: a first pivot hinge 31, a second pivot hinge 32, and a third pivot hinge 33; the second pivot hinge 32 and the third pivot hinge 33 are spaced apart, and the second pivot hinge 32 can pivotally engage with the second pivot hinge 32 and the third pivot hinge 33; the first pivot hinge 31, the second pivot hinge 32, and the third pivot hinge 33 are coaxially connected by a pivot shaft.
[0023] Thus, by pivoting and connecting the first pivot hinge 31, the second pivot hinge 32, and the third pivot hinge 33, a complete shaft hole structure is formed, overcoming the drawbacks of the shell-shaped circular hole structure design in the prior art. Furthermore, as mentioned above, the simplification of the mold structure directly leads to a significant reduction in mold manufacturing costs. It eliminates the need for complex side core-pulling mechanisms, deep hole machining, or special inserts, reducing the investment in mold materials, machining time, and assembly and debugging.
[0024] To improve the robustness of the connection between the upper cover 10 and the lower shell 20, in one embodiment, the pivot structure 30 is configured as two sets, with the two sets of pivot structures 30 spaced apart between the upper cover 10 and the opening. In this embodiment, each set of pivot structures 30 includes: three first pivot hinges 31, and a second pivot hinge 32, a third pivot hinge 33, and a second pivot hinge 32 arranged sequentially to cooperate with the three first pivot hinges 31.
[0025] For a specific structural form, the first pivot hinge 31 is inclined and includes: a first hinge body 311, a first pivot connection hole 312 disposed at one end of the first hinge body 311, and clearance grooves 313 disposed on both sides of the surface of one end of the first hinge body 311. In one embodiment, one end of the first hinge body 311 is a horizontally arranged cylindrical structure, which helps to increase the strength of the hinge.
[0026] The second pivot hinge 32 includes: a second hinge body 321 and a second pivot connection hole 322 disposed at the end of the second hinge body 321. One end of the second hinge body 321 is horizontally disposed, and the other end is inclined; the second pivot connection hole 322 is disposed at the inclined end of the second hinge body 321. In one embodiment, the inclined end of the second hinge body 321 is a laterally disposed cylindrical structure, which helps to increase the strength of the hinge.
[0027] The third hinge 33 includes: a third hinge body 331 and a third pivot connection hole 332 disposed at the end of the third hinge body 331. One end of the third hinge body 331 is horizontally disposed, and the other end is inclined; the third pivot connection hole 332 is disposed at the inclined end of the third hinge body 331. In one embodiment, the third hinge body 331 is a plug-in plate, so as to facilitate assembly between the two first pivot hinges 31.
[0028] Regarding the forming method, the first pivot hinge 31 can extend integrally from the opening of the lower shell 20; the second pivot hinge 32 and the third pivot hinge 33 can extend integrally from the edge of the upper cover 10.
[0029] In addition, for locking the upper cover 10 and the lower shell 20, the battery box also includes a latching structure 40. One end of the latching structure 40 is pivotally connected to one of the upper cover 10 or the lower shell 20, and the other end is engaged with the other end of the upper cover 10 or the lower shell 20.
[0030] In summary, this utility model's battery box replaces the original complex one-piece circular hole hinge structure with separate hinges on the upper and lower shells, which, when joined, form a complete shaft hole structure. This avoids the need for complex mechanisms such as deep hole machining or side core pulling on the mold. This significantly reduces the design and manufacturing difficulty of the mold. Furthermore, the simplified mold structure directly leads to a significant reduction in mold manufacturing costs. Eliminating complex side core pulling mechanisms, deep hole machining, or special inserts reduces the investment in mold materials, machining time, and assembly and debugging.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity.
