Detailed Implementation

[0032] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0033] This application provides a battery pack, which may include a housing, a target object, and a fixing component. The target object is disposed in the housing, and the fixing component can fix the target object to prevent it from shaking inside the housing.

[0034] It should be noted that the target object can include at least one of copper busbars, pipes, and cables. The fixing component can fix different types of target objects; for example, it can be used to fix copper busbars, pipes, or cables. The fixing component can also fix target objects of the same type but different sizes.

[0035] Specifically, the fixing component may include a preset carrier, a battery pack bracket 100 and multiple buckles. The preset carrier is located inside the box, and the battery pack bracket 100 is set on the preset carrier. The same battery pack bracket 100 can be used to cooperate with buckles of different sizes, and buckles of different sizes can be used to fix target objects of different sizes.

[0036] It should be noted that "target objects of different sizes" in this article can include target objects of different types and sizes, as well as target objects of the same type but different sizes.

[0037] It should be noted that the size of the target object can be understood as follows: for cylindrical targets, the size of the target object is the outer diameter of the target object; for non-cylindrical targets, the size of the target object is the outer perimeter of the cross-section of the target object.

[0038] In one embodiment, the preset carrier may include crossbeams, longitudinal beams, etc. inside the box.

[0039] In one embodiment, the buckle may include cable ties, spring clips, hooks, etc.

[0040] Figure 1 This is a schematic diagram of the structure of a battery pack bracket provided for an exemplary embodiment of this application. Figure 1 As shown, this application embodiment also provides a battery pack bracket 100, which may include a base 110 and a frame 120. The frame 120 is connected to the base 110, and the base 110 can be connected to the aforementioned preset carrier. The battery pack bracket 100 can be fixed on the preset carrier through the base 110.

[0041] In one embodiment, the base 110 and the frame 120 can be fixed by welding, bonding or other methods; or, the base 110 and the frame 120 can be integrally molded by injection molding; or, the base 110 and the frame 120 can be detachably connected by fasteners.

[0042] In one embodiment, the base 110 and the preset carrier can be fixed by welding, bonding or other means; or, the base 110 and the preset carrier can be detachably connected by fasteners.

[0043] like Figure 1 As shown, the frame 120 is provided with multiple mounting holes 130, at least some of which have different diameters. In this way, mounting holes 130 with different diameters can be adapted to buckles of different sizes, and buckles of different sizes can be used to snap and fix target objects of different sizes.

[0044] Therefore, the battery pack bracket 100, fixing assembly, and battery pack provided in this application embodiment, by providing multiple mounting holes 130 on the frame 120 and making at least some of the mounting holes 130 have different diameters, can realize the assembly of buckles of different sizes, thereby achieving the function of fixing target objects of different sizes. In this way, the same battery pack bracket 100 can be used to fix target objects of different sizes (including target objects of different types and different sizes, as well as target objects of the same type but different sizes), which can effectively improve the problem of poor bracket adaptability, reduce the number of battery pack brackets 100 used, and reduce the manufacturing cost of the battery pack.

[0045] It should be noted that at least some of the mounting holes 130 have different diameters, including some of the mounting holes 130 having different diameters than another part of the mounting holes 130; or, all of the mounting holes 130 have different diameters.

[0046] like Figure 1 As shown, the base 110 is provided with mounting holes 140. The base 110 can be fixed to a preset carrier through the mounting holes 140.

[0047] In one embodiment, the mounting hole 140 engages with a fastener (e.g., a bolt or stud), and the fastener is connected to a preset carrier, thereby fixing the base 110 relative to the preset carrier.

[0048] In one embodiment, there are multiple mounting holes 140, which are located along the length of the base 110 (see reference). Figure 1 (distributed at intervals along the X-axis).

[0049] like Figure 1 As shown, the battery pack bracket 100 may also include an inner liner 150 disposed within the mounting hole 140.

[0050] In practical applications, the inner liner 150 can be used to directly mate with fasteners. This improves the installation stability of the fasteners. Specifically, the battery pack bracket 100 is typically made of plastic (which has the advantages of low weight and low manufacturing cost), while the inner liner 150 is typically made of steel. Compared to the method of directly mates with the fasteners through the mounting holes 140, the method of directly mates with the fasteners through the inner liner 150 improves the installation strength and stability of the fasteners.

[0051] like Figure 1 As shown, a portion of the inner liner 150 protrudes relative to the surface of the seat 110. In this way, when the fastener and the inner liner 150 are engaged, the end of the fastener abuts against the protruding portion of the inner liner 150 relative to the surface of the seat 110, which can prevent the end of the fastener from directly acting on the surface of the seat 110 and prevent the surface of the seat 110 from being damaged by the fastener.

[0052] In one embodiment, the end of the liner 150 is provided with a flange 151, which is located outside the mounting hole 140. The flange 151 protrudes from the surface of the base 110, and the outer diameter of the flange 151 is larger than the diameter of the mounting hole 140. In this way, on the one hand, during the process of assembling the liner 150 into the mounting hole 140, the liner 150 abuts against the surface of the base 110, which can play a limiting role and prevent the liner 150 from dislodging from the mounting hole 140; on the other hand, after the fastener is assembled into the liner 150, the end of the fastener abuts against the flange 151, and the flange 151 can prevent the fastener from directly contacting the surface of the base 110, thus protecting the surface of the base 110.

[0053] It should be understood that the height of the inner lining 150 protruding from the surface of the seat 110 can be set according to the actual situation. For example, the height of the inner lining 150 protruding from the surface of the seat 110 may be 0.5 mm, 1 mm, etc.

[0054] like Figure 1 As shown, the base 110 is provided with a positioning hole 160. In practical applications, a positioning part can be provided on the preset carrier. During the process of assembling the base 110 onto the preset carrier, the positioning hole 160 cooperates with the positioning part of the preset carrier to quickly determine the installation position of the base 110, which plays the role of installation positioning and error prevention, and can effectively improve the installation efficiency and installation accuracy of the battery pack bracket 100.

[0055] In one embodiment, the positioning part on the preset carrier may include positioning pins, positioning protrusions, etc.

[0056] In one embodiment, the number of positioning holes 160 can be one, two, three, etc.

[0057] like Figure 1 As shown, the frame 120 may include a wall structure 125 and a plurality of reinforcing ribs 126. The wall structure 125 is connected to the base 110. The wall structure 125 can be used to set the aforementioned assembly holes 130. The plurality of reinforcing ribs 126 are connected to the wall structure 125, and some of the reinforcing ribs 126 are connected to the base 110. The plurality of reinforcing ribs 126 can improve the overall strength of the wall structure 125, making the wall structure 125 less prone to deformation, bending, or breakage.

[0058] It should be understood that the angle between the wall structure 125 and the base 110 can be set according to the actual situation, such as 60°, 90°, 120°, etc.

[0059] In one embodiment, the wall structure 125 and the reinforcing rib 126 are injection molded. The wall structure 125 facilitates the uniform flow of molten material during the injection molding process, which can improve the quality and efficiency of injection molding.

[0060] like Figure 1 As shown, the frame 120 may include a first frame 121 and a second frame 122, the first frame 121 and the second frame 122 being along the length direction of the base 110 (see reference). Figure 1 The components are distributed at intervals along the X-axis. In this way, the area between the first frame 121 and the second frame 122 can be used to avoid other components inside the box, thus preventing interference between the frame 120 and other components inside the box.

[0061] In one embodiment, both the first frame 121 and the second frame 122 are provided with mounting holes 130. The first frame 121 and the second frame 122 can be used to fix different target objects respectively, or to fix different parts of the same target object respectively.

[0062] In one embodiment, the portion of the base 110 located between the first frame 121 and the second frame 122 may be provided with mounting holes 140, and the area between the first frame 121 and the second frame 122 may facilitate the assembly of the liner 150 and fasteners by the workers.

[0063] Figure 2 A schematic diagram of the structure of a battery pack bracket provided as another exemplary embodiment of this application. (See diagram below.) Figure 2 As shown, the seat 110 may include a first seat 111 and a second seat 112, the first seat 111 and the second seat 112 being along the length direction of the frame 120 (see reference). Figure 2 The first seat 111 and the second seat 112 are spaced apart along the X-axis direction in the housing, and are connected by the frame 120. In this way, the area between the first seat 111 and the second seat 112 can be used to avoid other components inside the housing, thus preventing the seat 110 from interfering with other components inside the housing.

[0064] Figure 3 A schematic diagram of the structure of a battery pack bracket provided as another exemplary embodiment of this application. (See diagram below.) Figure 3 As shown, the frame 120 may include a third frame 123 and a fourth frame 124, which are respectively located in the thickness direction of the base 110 (see reference). Figure 3 On opposite sides along the Y-axis (in the middle), the third frame 123 and the fourth frame 124 are both provided with the aforementioned mounting holes 130. In this way, the third frame 123 and the fourth frame 124 can be used to fix different target objects on opposite sides of the base 110, or to fix the same target object at different locations on opposite sides of the base 110.

[0065] It should be noted that in practical applications, the appropriate installation location can be selected based on the distribution of the components inside the enclosure. Figure 1 , Figure 2 or Figure 3The battery pack bracket 100 shown is adapted to different installation environments inside the enclosure, which can effectively expand the application range of the battery pack bracket 100.

[0066] like Figures 1 to 3 As shown, the wall structure 125 mentioned above may include a side wall 1251 and a top wall 1252. The side wall 1251 is connected to the base 110, and the top wall 1252 is connected to the side of the side wall 1251 away from the base 110. The aforementioned mounting hole 130 may be provided on the side wall 1251 (see reference). Figure 3 Alternatively, the aforementioned mounting hole 130 can be provided on the top wall 1252 (see reference). Figure 1 and Figure 2 Alternatively, mounting holes 130 can be provided on both the side wall 1251 and the top wall 1252. In one embodiment, the side wall 1251 and the base 110 can be arranged vertically or inclined relative to each other.

[0067] like Figure 1 and Figure 2 As shown, the top wall 1252 includes multiple steps, and at least some of the steps have mounting holes 130 on their step surfaces 12521. In practical applications, the number of steps, the distribution of multiple steps, and the step height of different steps can be set according to the distribution of various components inside the housing, so that the area between multiple steps can be used to avoid target objects and other components inside the housing, preventing mutual interference and facilitating installation.

[0068] In one embodiment, a portion of the step surface 12521 may be provided with mounting holes 130; alternatively, all the step surfaces 12521 may be provided with mounting holes 130.
