For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Example 1

[0037] The battery pack fixing member provided in this embodiment is used for connecting the upper shell and the lower shell of the battery pack.

[0038] like Figure 1 and Figure 2 As shown, a specific implementation of the battery pack fixing component provided in this embodiment includes a first clamping member 1, a second clamping member 3 and a connecting member 7, the first clamping member 1 has a first clamping section 2; the second clamping member 3 has a second clamping section 4; the connecting member 7 connects the first clamping member 1 and the second clamping member 3 respectively, and a clamping space for accommodating the member to be clamped is defined between the first clamping member 1, the second clamping member 3 and the connecting member 7; the first clamping section 2 and / or the second clamping section 4 can produce elastic deformation to clamp the member to be clamped.

[0039] The connection member 7 not only serves as a connection between the two clamping sections, but also further improves the fixing stability of the fixing member, thereby preventing the clamped member from moving easily in the clamping space.

[0040] Specifically, the connecting member 7 includes but is not limited to Figure 1 The sheet structure shown in the figure, the connecting member 7 can also be an arc-shaped structure; the first clamping section 2 and the second clamping section 4 are symmetrically arranged along the center plane of the connecting member 7, so that the forces exerted on the two clamping sections are the same, and the clamping is more stable.

[0041] The battery pack fixing member replaces the traditional bolts to connect the clamped parts in the battery pack, namely the upper shell and the lower shell. The assembly can be performed in any order, and the battery pack fixing member can be reused, which reduces the process flow and cost of assembling the upper shell and the lower shell. The operation is easy to use and reduces the installation time. When clamping is required, the first clamping section and / or the second clamping section are elastically deformed by external force to expand the clamping space to accommodate the clamped parts, and the upper shell and the lower shell are clamped by the elastic recovery of the first clamping section and / or the second clamping section.

[0042] Specifically, the first clamping member 1 and the second clamping member 3 may be made of a stainless steel material capable of producing elastic deformation. It should be noted that the present application does not limit the specific material, and any stainless steel material capable of producing elastic deformation known in the prior art may be used.

[0043] In a specific implementation manner, the first clamping member 1 and the second clamping member 3 are symmetrically arranged, and the first clamping section 2 and the second clamping section 4 can both produce elastic deformation and clamp the top and the bottom of the clamped member at the same time.

[0044] In addition, as an alternative embodiment, only one of the first clamping section 2 and the second clamping section 4 can produce elastic deformation, and the other is a horizontally arranged fixing member. When clamping is required, the one that can produce elastic deformation is deformed by external force to expand the clamping space. After the clamped object is placed in the clamping space, the one that can produce elastic deformation is released. Under the effect of elastic recovery, the first clamping section 2 and the second clamping section 4 cooperate to complete the clamping.

[0045] In a specific implementation manner, the first clamping section 2 and the second clamping section 4 are both sheet-type structures. The arrangement of the sheet-type structure can achieve maximum clamping surface contact, better clamping effect, and greater clamping force.

[0046] like Figure 1 and Figure 2As shown, the battery pack fixing component provided in this embodiment, the first clamping member 1 also includes a first connecting section 8, and the first clamping section 2 is connected to the connecting member 7 through the first connecting section 8; the second clamping member 3 also includes a second connecting section 9, and the second clamping section 4 is connected to the connecting member 7 through the second connecting section 9; wherein, the first connecting section 8 and / or the second connecting section 9 can produce elastic deformation to adapt to the thickness of the member to be clamped. The provision of the first connecting section 8 and the second connecting section 9 makes the battery pack fixing component more versatile, and can be used in the shell connection of battery packs of different thicknesses. With such a provision, when clamping, it is necessary to overcome the elasticity between the two clamping sections and the elasticity between the two connecting sections, and the clamping effect is better.

[0047] Specifically, the first connecting section 8 and the second connecting section 9 include but are not limited to Figure 1 The sheet-type structure shown in can also be an arc-shaped structure.

[0048] In a specific implementation manner, both the first connecting section 8 and the second connecting section 9 can generate elastic deformation, and the first connecting section 8 and the second connecting section 9 are symmetrically arranged on the connecting member 7 .

[0049] In addition, as an alternative embodiment, only one of the first connecting section 8 and the second connecting section 9 may have elastic deformation capability, and the one of the first connecting section 8 and the second connecting section 9 with elastic deformation capability corresponds to the one of the first clamping section 2 and the second clamping section 4 that can produce elastic deformation. With such a configuration, adaptation to the thickness of the clamped part can be achieved by simply adjusting the first clamping section 2 and the first connecting section 8, or simply adjusting the second clamping section 4 and the second connecting section 9.

[0050] like Figure 1 and Figure 5 As shown, in the battery pack fixing component provided in this embodiment, the height dimension of the connecting member 7 is greater than the thickness of the member to be clamped, so that after the clamping is completed, the first connecting section 8 and the second connecting section 9 will not reach the elastic limit position, avoiding elastic failure after a long period of deformation, affecting the clamping effect, and ensuring its greater clamping force.

[0051] In addition, as an alternative embodiment, the first connecting section 8 and the second connecting section 9 may not be provided, and the connecting member 7 directly connects the first clamping section 2 and the second clamping section 4. In this case, the height dimension of the connecting member 7 is set to be consistent with the thickness of the part to be clamped, so that after elastic deformation, the part to be clamped can be clamped with the maximum contact area.

[0052] like Figure 5As shown, the battery pack fixing member provided in this embodiment, when clamping is required, the first clamping section 2 and the second clamping section 4 abut against the top and bottom of the part to be clamped, and the inner side wall of the connecting member 7 abuts against the side wall of the part to be clamped.

[0053] By setting the first clamping section 2 and the second clamping section 4 to abut against the top and bottom of the part to be clamped, and the inner wall of the connecting member 7 to abut against the side wall of the part to be clamped, good contact is achieved between the battery pack fixing component and the part to be clamped, and the clamping of the part to be clamped can be achieved with the maximum contact area, thereby ensuring firm clamping and achieving a better clamping effect.

[0054] like Figure 1 As shown, in the battery pack fixing member provided in this embodiment, one end of the clamping space close to the connecting piece 7 is a first opening end 10, and the other end is a second opening end 11. In the initial state of the battery pack fixing member, the height dimension of the first opening end 10 is greater than the height dimension of the second opening end 11.

[0055] Specifically, for example, in an embodiment including a first connecting segment 8 and a second connecting segment 9, the cross-sectional shape of the clamping space between the first connecting segment 8 and the second connecting segment 9 is a trapezoidal structure, and the cross-sectional shape of the clamping space between the first clamping segment 2 and the second clamping segment 4 is a trapezoidal structure or a triangular structure. When the size of the first opening end 10 is the same, the smaller the opening size of the second opening end 11, the greater the clamping force.

[0056] In the battery pack fixing component provided in this embodiment, the first clamping member 1, the second clamping member 3 and the connecting member 7 are an integrally formed structure. The setting of the integrally formed structure ensures that the clamping section and the connecting section have good elastic deformation ability.

[0057] Example 2

[0058] like Figures 3 to 5 As shown, a specific implementation of the battery pack provided in this embodiment includes a shell body and the battery pack fixing member described in Example 1, the shell body includes an upper shell 12 and a lower shell 13, the upper shell 12 has an upper connecting plate 14, the lower shell 13 has a lower connecting plate 15, and the battery pack fixing member is clamped on the shell body to fix the upper connecting plate 14 and the lower connecting plate 15. The fixing is completed by the battery pack fixing member, the operation is simple, and the process flow and cost are reduced.

[0059] Furthermore, a first limiting portion 5 is provided on the first clamping section 2 and the second clamping section 4 of the battery pack fixing component, and a second limiting portion 6 is provided on the upper connecting plate 14 and the lower connecting plate 15 of the shell body; the first limiting portion 5 cooperates with the second limiting portion 6.

[0060] like Figure 1 , Figure 2 and Figure 5 As shown, the first limiting portion 5 is a protrusion or a groove, and the second limiting portion 6 is a groove or a protrusion that cooperates with the first limiting portion 5. The cooperation between the protrusion and the groove provides a limit to the battery pack fixing component to prevent the battery pack fixing component from easily falling out.

[0061] In a specific embodiment, the first limiting portion 5 is a groove, which is arranged on the inner side walls of the first clamping section 2 and the second clamping section 4, and the second limiting portion 6 is a protrusion, which is arranged on the upper connecting plate 14 and the lower connecting plate 15; specifically, the protrusion can be a full-length rectangular protrusion structure arranged along the length direction of the upper connecting plate 14, or it can be a short protrusion structure arranged at intervals; in addition, as an alternative embodiment, the protrusions on the upper connecting plate 14 and the lower connecting plate 15 can also be circular structures, and multiple protrusions are arranged, and circular grooves are arranged on the clamping sections, and the circular grooves and circular protrusions are arranged one by one.

[0062] During actual use, the battery pack fixing component can be installed by using a push clamp, saving time and effort; the battery pack fixing component is suitable for various types of battery packs, such as battery packs with profile structures or sheet metal structures.

[0063] like Figure 1 As shown, the battery pack provided in this embodiment has a plurality of battery pack fixing members, and the plurality of battery pack fixing members are sandwiched at intervals on the upper connecting plate 14 and the lower connecting plate 15 to ensure uniform clamping.

[0064] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present utility model.
