DETAILED DESCRIPTION

[0035] 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.

[0036] Figure 1 A schematic diagram of the structure of a wiring harness isolation plate provided by an exemplary embodiment of the present application. The wiring harness isolation plate 100 provided by the embodiment of the present application may include an outer frame 110 and a plurality of inner brackets 130, wherein the plurality of inner brackets 130 are slidably matched with the inner wall of the outer frame 110, and a plurality of mounting areas 140 are formed between the plurality of inner brackets 130 and the outer frame 110, and each mounting area 140 may be used to accommodate a busbar.

[0037] It should be noted that by operating the plurality of inner brackets 130 to slide relative to the outer frame 110 , the sizes of the plurality of installation areas 140 can be adjusted, so that the installation areas 140 after the size adjustment can be used to adapt to the busbars with changed sizes.

[0038] Specifically, when the number of battery cells in the battery changes but the overall size of the battery does not change, it means that the size of each battery cell has changed, and correspondingly, the size of the bus on each battery cell has also changed. In this case, the number of inner brackets 130 is adjusted, and then the multiple inner brackets 130 are operated to slide relative to the outer frame 110, and the sizes of the multiple installation areas 140 are adjusted. The adjusted sizes of the installation areas 140 are adapted to the bus on the battery cells after the size change. In this way, replacement of different types of wiring harness isolation plates 100 can be avoided, which not only improves assembly efficiency, but also eliminates the need to prepare different types of wiring harness isolation plates 100, thereby reducing resource waste.

[0039] Figure 2 A schematic structural diagram of an outer frame provided for an exemplary embodiment of the present application. Figure 3 for Figure 2 A magnified schematic diagram of center A. Figure 4 A schematic structural diagram of a connecting plate provided for an exemplary embodiment of the present application. Figure 5 for Figure 4 A magnified schematic diagram of point B in the middle. Figure 6 A schematic diagram of the structure of the inner bracket 130 provided by an exemplary embodiment of the present application. Figures 1 to 6 As shown, the outer frame 110 includes a first side wall 111, and the first side wall 111 is provided with a first slide groove 114. A connecting plate 150 is also provided in the outer frame 110, and the side wall of the connecting plate 150 is provided with a second slide groove 151; correspondingly, the inner bracket 130 includes a first sliding body 131 and a second sliding body 132 arranged opposite to each other, and the inner bracket 130 is arranged between the connecting plate 150 and the first side wall 111, and the first sliding body 131 is slidably matched with the first slide groove 114, and the second sliding body 132 is slidably matched with the second slide groove 151.

[0040] It should be understood that when the size of the installation area 140 needs to be adjusted, the inner bracket 130 is operated to slide, the first slide body 131 slides along the first slide groove 114, and the second slide body 132 slides along the second slide groove 151. The first slide groove 114 and the second slide groove 151 guide the inner bracket 130 to prevent the inner bracket 130 from deviating from the predetermined path.

[0041] Combination Figure 1 and Figure 2 In one embodiment, there are two first side walls 111, which are arranged opposite to each other and parallel to each other. Second slide grooves 151 are provided on opposite sides of the connecting plate 150, wherein the first slide groove 114 of one of the first side walls 111 corresponds to one of the second slide grooves 151, and the first slide groove 114 of the other first side wall 111 corresponds to the other second slide groove 151.

[0042] like Figure 5As shown, the connecting plate 150 is provided with a notch 152, and the notch 152 is connected to the second slide groove 151. In practical applications, the second slide body 132 can be passed through the notch 152, so that the second slide body 132 is inserted into the second slide groove 151 or the second slide body 132 is moved to the second slide groove 151, so as to facilitate and quickly adjust the number of the inner brackets 130 and improve the adjustment efficiency.

[0043] In one embodiment, the number of the notches 152 may be one, two, or the like.

[0044] like Figure 3 and Figure 6 As shown, the inner wall of the first slide groove 114 is recessed with a limiting groove 115, and the first sliding body 131 is provided with a barb 133, and the barb 133 is embedded in the limiting groove 115. In this way, the matching structure of the barb 133 and the limiting groove 115 can limit the first sliding body 131 from detaching from the first slide groove 114, thereby improving the stability of the inner bracket 130 during the sliding process.

[0045] like Figure 6 As shown, in one embodiment, the first sliding body 131 is a U-shaped body, and both ends of the first sliding body 131 are provided with hooks 133. In this way, in the process of assembling the first sliding body 131 into the first sliding groove 114, the front and back sides of the first sliding body 131 can achieve the cooperation between the hooks 133 and the limiting grooves 115, and there is no need to deliberately adjust the posture of the first sliding body 131, which can effectively improve the assembly efficiency.

[0046] like Figure 6 As shown, the inner bracket 130 may also include a first carrier 134, a first boss 135 and a second boss 153. The first boss 135 and the second boss 153 are both arranged on the first carrier 134. The first carrier 134, the first boss and the second boss 153 can limit the movement of the bus in different directions to ensure the stability of the bus assembly in the installation area 140.

[0047] Specifically, the bus is placed on the first carrier 134, the first carrier 134 is used to support the bus and limit the movement of the bus along the first direction, the first boss 135 and the second boss 153 are arranged perpendicular to each other, the first boss 135 abuts the bus to limit the movement of the bus along the second direction relative to the first carrier 134, and the second boss 153 abuts the bus to limit the movement of the bus along the third direction relative to the first carrier 134.

[0048] It should be noted that the first direction, the second direction and the third direction are perpendicular to each other. In practical applications, Figure 2 As shown, the directions of the X-axis, the Y-axis, and the Z-axis in the spatial rectangular coordinate system can be used to represent the second direction, the third direction, and the first direction, respectively.

[0049] like Figure 6 As shown, the first boss 135 can separate the first carrier 134 into two adjacent carrier portions 1341 . The two adjacent carrier portions 1341 can be used to carry unused bus bars respectively. The second boss 153 is disposed on both carrier portions 1341 .

[0050] like Figure 6 As shown, a first clamping block 136 is provided on one side of the first boss 135 away from the first carrier 134. The first clamping block 136 is used to clamp the busbar, and the first clamping block 136 can limit the busbar from being separated from the first carrier 134 along the first direction. In this way, under the clamping action of the first clamping block 136 and the first carrier 134, the busbar can be more stably held on the inner bracket 130.

[0051] In one embodiment, first clamping blocks 136 may be disposed at opposite ends of the first protrusion 135 to clamp the opposite ends of the bus bar, thereby further improving the assembly stability of the bus bar.

[0052] like Figure 1 and Figure 6 As shown, a third slide groove 137 and a third slide body 138 are provided at opposite ends of the first carrier 134 . In two adjacent inner brackets 130 , the third slide body 138 of one inner bracket 130 slidably cooperates with the third slide groove 137 of the other inner bracket 130 .

[0053] Specifically, in practical applications, after the size of the busbar changes, the relative position between the two adjacent inner brackets 130 is adjusted through the cooperation of the third sliding body 138 and the third sliding groove 137, thereby changing the size of the installation area 140 between the two inner brackets 130, so that the size of the adjusted installation area 140 is adapted to the size of the busbar. It should be understood that the cooperation structure of the third sliding body 138 and the third sliding groove 137 can play a good guiding role in the process of relative sliding of the two adjacent inner brackets 130, thereby preventing the two adjacent inner brackets 130 from deviating from the predetermined path.

[0054] like Figure 6 and Figure 8 As shown, the outer frame 110 includes a second side wall 112 and a third side wall 113 that are oppositely arranged. The second side wall 112 is provided with a fourth sliding body 116 , and the third side wall 113 is provided with a connecting body 117 . The connecting body 117 is provided with a fourth sliding groove 118 .

[0055] In practical applications, the fourth slide body 116 is slidably matched with the third slide groove 137 of the inner bracket 130 closest to the second side wall 112, and the fourth slide groove 118 is slidably matched with the third slide body 138 of the inner bracket 130 closest to the third side wall 113. In this way, not only the stability of the inner bracket 130 after assembly can be ensured, but also the sliding of the inner bracket 130 relative to the outer frame 110 can be facilitated, and the adjustment efficiency of the size of the installation area 140 can be effectively improved.

[0056] like Figure 3 and Figure 8 As shown, the second side wall 112 is protruded toward the installation area 140 with a second carrier 119 and a second block 120 that are spaced apart. In actual application, a portion of the bus is disposed between the second carrier 119 and the second block 120. The second carrier 119 and the second block 120 are used to hold the bus to improve the stability of the bus after assembly.

[0057] Similarly, the third side wall 113 is provided with second carriers 119 and second clamping blocks 120 that are spaced apart and protrude toward the mounting area 140 . The second carriers 119 and second clamping blocks 120 can also be used to clamp the busbar close to the third side wall 113 .

[0058] like Figure 3 As shown, a groove 121 is formed on the top of the third side wall 113 . After the busbar is assembled into the mounting area 140 , the groove 121 can be used to accommodate a portion of the busbar so as to facilitate connection between the busbar and components outside the outer frame 110 .

[0059] Combination Figure 2 In one embodiment, the groove 121 may also be disposed on the top of the second side wall 112 .

[0060] The embodiment of the present application further provides a battery, which includes the wiring harness isolation plate 100 described in the above embodiment and has all the functions of the wiring harness isolation plate 100.
