DETAILED DESCRIPTION

[0037] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0038] Figure 1 This is a schematic diagram of a portion of a bracket assembly and a battery box provided by an exemplary embodiment of the present application. Figure 1 As shown, the bracket assembly 100 provided in the embodiment of the present application may include a bracket body 110 and an anti-rotation buckle 160. The bracket body 110 is provided with a first installation space 120. The copper busbar 200 can be fixed in the first installation space 120 so that the copper busbar 200 and the bracket body 110 are relatively fixed. Furthermore, the anti-rotation buckle 160 is connected to the bracket body 110. The anti-rotation buckle 160 is located on the outside of the bracket body 110. The anti-rotation buckle 160 can be used to clamp the battery box 300. In this way, the anti-rotation buckle 160 can be fixed relative to the battery box 300.

[0039] It should be understood that, since the bracket body 110 is connected to the anti-rotation buckle 160, after the anti-rotation buckle 160 is snapped onto the battery box 300, the bracket body 110 can also be fixed relative to the battery box 300; and, since the copper busbar 200 is fixed in the first installation space 120, when the bracket body 110 is fixed relative to the battery box 300, the copper busbar 200 can also be fixed relative to the battery box 300. In this way, the problem of the copper busbar 200 being easily moved relative to the battery box 300 can be effectively improved, and relative movement between the copper busbar 200 and components can be avoided, thereby effectively ensuring that the battery pack can work normally.

[0040] In one embodiment, a crossbeam may be provided in the battery box 300 , and the crossbeam may serve as a mounting carrier for the bracket assembly 100 . The anti-rotation buckle 160 is clipped onto the crossbeam, so that the bracket body 110 is fixed relative to the crossbeam.

[0041] Figure 2This is a schematic diagram of the structure of the adjusting member, the base frame and the anti-rotation buckle provided by an exemplary embodiment of the present application. Figure 1 and Figure 2 As shown, the anti-rotation buckle 160 includes a connecting plate 161 and a plurality of clips 162. The connecting plate 161 is connected to the bracket body 110. The plurality of clips 162 are connected to a side of the connecting plate 161 away from the bracket body 110. The plurality of clips 162 are distributed along the circumference of the connecting plate 161. The plurality of clips 162 are all used to clip into the battery box 300.

[0042] It should be understood that multiple clips 162 are all snapped into the battery box 300, which can improve the snap-on stability between the anti-rotation buckle 160 and the battery box 300, making it difficult for the anti-rotation buckle 160 to move or shake relative to the battery box 300, thereby further improving the stability of the copper busbar 200 relative to the battery box 300 and ensuring that the copper busbar 200 and components are not easily loose relative to each other.

[0043] In one embodiment, the connection plate 161 and the bracket body 110 may be connected together by welding, bonding, clamping, etc.

[0044] like Figure 1 and Figure 2 As shown, the bracket body 110 may include a base frame 140 and a fixing frame 150, the base frame 140 includes a first side 141 and a second side 142 that are oppositely arranged, the first side 141 is connected to the anti-rotation buckle 160, the fixing frame 150 and the base frame 140 are stacked and distributed, and a first installation space 120 is formed between the fixing frame 150 and the second side 142. The aforementioned copper busbar 200 is fixed in the first installation space 120. It can be understood that the fixing frame 150 and the second side 142 play a fixing role on the copper busbar 200, and the copper busbar 200 is fixed between the fixing frame 150 and the second side 142.

[0045] like Figure 1 and Figure 2 As shown, the bracket body 110 may further include an adjusting member 130, the adjusting member 130 is connected to the base frame 140, and the fixing frame 150 is movably connected to the adjusting member 130. It should be understood that during the movement of the fixing frame 150 relative to the adjusting member 130, the distance between the fixing frame 150 and the second side 142 will change, so that the height of the first installation space 120 changes accordingly.

[0046] It should be noted that when the fixing frame 150 moves to the target position relative to the adjusting member 130, the adjusting member 130 can limit the fixing frame 150 at the target position, thereby limiting the fixing frame 150 and the base frame 140 to the current distance. In other words, by moving the fixing frame 150 to different target positions, the fixing frame 150 and the base frame 140 can be at different distances, and the adjusting member 130 can limit the fixing frame 150 and the base frame 140 to different distances. In this way, in practical applications, the position of the fixing frame 150 can be adjusted according to the number of copper bars 200 and the height of the stack. After the position adjustment of the fixing frame 150 is completed, the adjusting member 130 can limit the fixing frame 150 and the base frame 140 to the current distance, so that the first installation space 120 between the fixing frame 150 and the base frame 140 can meet the demand for fixing the copper bar 200, effectively expanding the application range of the bracket assembly 100, and being able to achieve a fixing effect for copper bars 200 of different numbers and heights.

[0047] Figure 3 This is a schematic diagram of the structure of a fixing frame provided by an exemplary embodiment of the present application. Figures 1 to 3 As shown, the fixing frame 150 is provided with an assembly hole 154, and a plurality of first latch teeth 170 are provided in the assembly hole 154. The adjusting member 130 is provided with a plurality of second latch teeth 131. After the adjusting member 130 is matched with the assembly hole 154, some of the second latch teeth 131 can be engaged with the first latch teeth 170 in the assembly hole 154.

[0048] It should be understood that after the second latch 131 is engaged with the first latch 170 in the assembly hole 154, the adjustment member 130 can limit the fixing frame 150 and the base frame 140 at the current distance. After the fixing frame 150 and the base frame 140 fix the copper busbar 200, relative looseness is not likely to occur, and the copper busbar 200 can be continuously fixed.

[0049] In practical applications, according to the stacking condition of the copper busbars 200, if it is necessary to adjust the distance between the fixing frame 150 and the base frame 140, the adjusting member 130 can be pulled so that the second latching teeth 131 at different positions are engaged with the first latching teeth 170 in the assembly holes 154. In this way, the distance between the fixing frame 150 and the base frame 140 can be adjusted, and the fixing frame 150 and the base frame 140 are limited to the current distance.

[0050] In one embodiment, the adjusting member 130 may be a cable tie, a rack, or the like.

[0051] like Figures 1 to 3As shown, the second side 142 of the base frame 140 is provided with a first positioning groove 143, and a positioning body 151 is convexly provided on one side of the fixing frame 150 close to the second side 142. In the process of assembling the fixing frame 150 on the base frame 140, the positioning body 151 can cooperate with the first positioning groove 143 to improve the assembly efficiency and assembly accuracy of the fixing frame 150 and the base frame 140, and ensure that the fixing frame 150 and the base frame 140 can play an ideal fixing effect on the copper busbar 200.

[0052] It should be noted that the number of the first positioning grooves 143 may be one, two, three, four, etc. Correspondingly, the number of the positioning bodies 151 may be one, two, three, four, etc.

[0053] In one embodiment, the number of the first positioning grooves 143 is four, and the four first positioning grooves 143 are located at the four vertices of the rectangle in the second side 142. The number of the positioning bodies 151 is four, and the four positioning bodies 151 are located at the four vertices of the rectangle on one side of the fixing frame 150 close to the second side 142. The four positioning bodies 151 correspond one-to-one to the four first positioning grooves 143, which can improve the assembly accuracy and assembly stability between the base frame 140 and the fixing frame 150.

[0054] Figure 4 This is a schematic diagram of the structure of a fixing frame provided by another exemplary embodiment of the present application. Figure 4 As shown, the positioning body 151 may include a support column 1511 and a boss 1512, the support column 1511 includes a first end 15111 and a second end 15112 that are relatively arranged, the first end 15111 is connected to a side of the fixing frame 150 close to the second side 142, the boss 1512 is connected to the second end 15112, and the projection of the boss 1512 on the end surface of the second end 15112 is located within the outer contour of the end surface of the second end 15112.

[0055] During the process of assembling the fixing frame 150 and the base frame 140, the boss 1512 cooperates with the first positioning groove 143 to play a guiding and positioning role, thereby improving the assembly efficiency and accuracy of the fixing frame 150 and the base frame 140. The support column 1511 abuts against the second side 142 to support the fixing frame 150, thereby facilitating the formation of a first installation space 120 for fixing the copper busbar 200 between the fixing frame 150 and the base frame 140.

[0056] In one embodiment, the boss 1512 is adapted to the shape of the first positioning groove 143. For example, if the first positioning groove 143 is a rectangular groove, the boss 1512 can be a corresponding cuboid; if the first positioning groove 143 is a cylindrical groove, the boss 1512 can be a corresponding cylinder.

[0057] like Figure 4As shown, a pressure body 153 is provided on one side of the fixing frame 150 close to the second side 142, and the pressure body 153 is used to press the copper busbar 200 in the first installation space 120 to fix the copper busbar 200 in the first installation space 120, prevent the copper busbar 200 from shaking in the first installation space 120, and prevent the copper busbar 200 from escaping from the first installation space 120.

[0058] like Figure 4 As shown, the pressing body 153 includes two relatively arranged pressure strips 1531, and the two pressure strips 1531 are used to press different parts of the copper busbar 200, which can further improve the stability of the copper busbar 200 in the first installation space 120 and further prevent the copper busbar 200 from shaking in the first installation space 120.

[0059] Figure 5 This is a schematic diagram of the structure of a layering strip provided by an exemplary embodiment of the present application. Figure 5 As shown, the pressure strip 1531 includes a connecting section 15311 and a pressing section 15312, one end of the connecting section 15311 is connected to a side of the fixing frame 150 close to the second side 142, the pressing section 15312 is connected to an end of the connecting section 15311 away from the fixing frame 150, and the angle between the connecting section 15311 and the pressing section 15312 is an obtuse angle. In this way, when pressing and fixing the copper bar 200, the pressing section 15312 can directly contact the copper bar 200, and the contact area between the pressing section 15312 and the connecting section 15311 and the copper bar 200 is large, so that the copper bar 200 is prevented from being damaged due to stress concentration, and the copper bar 200 is better protected.

[0060] In one embodiment, the pressure strip 1531 may be made of plastic material and press the copper busbar 200 through plastic deformation.

[0061] like Figures 1 to 4 As shown, the second positioning groove 152 and the aforementioned positioning body 151 are respectively provided on the opposite sides of the fixing frame 150. There are multiple fixing frames 150, and the multiple fixing frames 150 are stacked and distributed. In two adjacent fixing frames 150, the positioning body 151 of the upper fixing frame 150 cooperates with the second positioning groove 152 of the lower fixing frame 150, and a second installation space 180 for fixing the copper busbar 200 is formed between any two adjacent fixing frames 150.

[0062] It should be understood that different second installation spaces 180 can be used to fix different copper bars 200 , so that the number of fixed copper bars 200 can be increased.

[0063] It should be understood that, in the process of assembling two adjacent fixing frames 150 with each other, the positioning body 151 of the upper fixing frame 150 cooperates with the second positioning groove 152 of the lower fixing frame 150, so as to improve the assembly efficiency and assembly accuracy of the two adjacent fixing frames 150, and ensure that the two adjacent fixing frames 150 can achieve an ideal fixing effect on the copper busbar 200.

[0064] It should be noted that the number of the second positioning grooves 152 can be one, two, three, four, etc. Correspondingly, the number of the positioning bodies 151 can be one, two, three, four, etc.

[0065] In one embodiment, the number of the second positioning grooves 152 is four, and the four second positioning grooves 152 are located at the four vertices of the rectangle. The number of the positioning bodies 151 is four, and the four positioning bodies 151 are located at the four vertices of the rectangle. The four positioning bodies 151 correspond one-to-one to the four first positioning grooves 143, which can improve the assembly accuracy and assembly stability between two adjacent fixing frames 150.

[0066] like Figures 1 to 4 As shown, the aforementioned adjustment member 130 can also movably connect multiple fixing frames 150, and the adjustment member 130 can limit any two adjacent fixing frames 150 at different distances. In this way, the heights of different second installation spaces 180 can be adjusted, so that different second installation spaces 180 can be at different heights according to the stacking conditions of the copper busbars 200 to fix the copper busbars 200 in different stacking conditions, thereby effectively expanding the application range of the bracket assembly 100.

[0067] In one embodiment, part of the second latching teeth 131 of the adjusting member 130 may be engaged with the first latching teeth 170 in the assembly holes 154 of two adjacent fixing frames 150 , thereby limiting the two adjacent fixing frames 150 to a current distance.

[0068] In one embodiment, each fixing frame 150 may also be provided with the aforementioned pressing body 153 (refer to the positional relationship and connection relationship between the aforementioned pressing body 153 and the fixing frame 150). In two adjacent fixing frames 150, the pressing body 153 of the upper fixing frame 150 may be used to press against the copper busbar 200 in the second installation space 180, thereby improving the stability of the copper busbar 200 in the second installation space 180.

[0069] The embodiment of the present application further provides a battery pack, which may include a battery box 300 and a bracket assembly 100, wherein the bracket assembly 100 is located in the battery box 300, and the anti-rotation buckle 160 of the bracket assembly 100 is engaged with the battery box 300.

[0070] It should be understood that the battery pack has all the functions of the bracket assembly 100 , and the beneficial effects of the battery pack can refer to the beneficial effects of the aforementioned bracket assembly 100 .
