[0033] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] Reference Figures 1 to 6As shown, this embodiment provides a light storage integrated machine 100, including a box 101 and a battery wiring module arranged in the box 101. The box 101 includes a first box 1012 and a second box 1013, and the second box 1013 has a bottom wall 1011. Specifically, the first box 1012 is an upper box, and the second box 1013 is a lower box. A plurality of power components are arranged in the upper box, and a battery is arranged in the lower box. One end of the battery wiring module is connected to the battery, and the other end is connected to the power component.

[0035] Furthermore, the battery wiring module includes a copper busbar 1, one end of which is used to connect to the battery of the integrated photovoltaic and storage device 100, and the other end is used to connect to the power components of the integrated photovoltaic and storage device 100. Furthermore, the copper busbar 1 has multiple wiring parts 11, and the multiple wiring parts 11 are in different multiple planes for connection with multiple wiring terminals, and the multiple wiring terminals are used to connect multiple batteries. During operation, the rivet nut 6 is first crimped on the wiring part 11, and then the wiring terminal and the wiring part 11 are locked together by screws. The wiring terminals and batteries here are not shown in the figure. The wiring terminals of this embodiment specifically refer to OT terminals, and the batteries are specifically storage batteries.

[0036] Furthermore, combined with Figure 5 As shown, multiple planes are parallel to each other and have a spacing, each wiring portion 11 is configured to be connected to a wiring terminal, and the distance between two adjacent wiring portions in the first direction is 19-25mm. Specifically in this embodiment, the distance between two adjacent wiring portions in the first direction is 20mm, and sufficient wiring space is reserved, and the OT terminals will not interfere with each other. It should be noted that the first direction here refers to the height direction. The same copper bus 1 is connected to multiple wiring terminals, and the wiring terminals are arranged in a staggered manner. The staggered arrangement not only saves space, but also prepares for wiring.

[0037] There are at least two copper bars, wherein the wiring portion 11 of one copper bar 1 is used to connect the positive terminal of the battery, and the other is used to connect the negative terminal of the battery. Specifically in the present embodiment, the number of the wiring portion 11 and the copper bar 1 is two, and the wiring portion is in two parallel planes with a spacing. The wiring portion 11 of one copper bar 1 connects the positive terminal of two groups of batteries, and the wiring portion 11 of the other copper bar connects the negative terminal of two groups of batteries. That is, a pair of copper bars can be used to connect two groups of batteries. Compared with the two pairs of copper bars in the prior art that connect two groups of batteries, not only is the structure relatively simple, the production cost is reduced, but also the internal space of the optical storage integrated machine is saved. It should be noted that in other embodiments, the number of the wiring portion 11 may not be limited to two, but may be three or even more, corresponding to more groups of batteries that can be connected. The number of the wiring portion 11 is not limited here, and can be adjusted according to actual usage.

[0038] Combination Figure 2 and Figure 6 As shown, the battery wiring module also includes a copper bar support device 2 for supporting the copper bar 1. One copper bar support device 2 corresponds to one copper bar 1 and the structural shape of the copper bar support device 2 is designed according to the structure of the copper bar, so that the copper bar can be easily fixed. Furthermore, the copper bar support device 2 and the housing 101 of the integrated optical storage device 100 are fixedly connected by a first fixing component 3, and the copper bar support component 2 and the copper bar 1 are fixedly connected by a second fixing component 4.

[0039] Specifically, the first fixing component 3 is specifically a rivet screw 31 and a flange nut 32. During the specific operation, two rivet screws 31 are firstly riveted on the bottom wall 1011 (lower surface) of the box body 101. The bottom of the copper bar support device 2 passes through the rivet screws 31 and is locked by the flange nut 32, so that the copper bar support device 2 and the box body 101 are fixedly connected. The second fixing component 4 includes a nut 41 and a screw 42, and the nut is a copper nut. During the specific operation, two copper nuts are first embedded on the copper bar support device 2, and the height of the copper nuts cannot exceed the upper surface of the copper bar support device 2. The copper bar 1 is placed on the copper bar support device 2 and locked by the screw 42, so that the copper bar 1 and the copper bar support device 2 are fixedly connected.

[0040] The copper bar support device is made of plastic, which has excellent insulation and can be well combined with copper nuts. On the other hand, plastic can be easily processed into various complex shapes and sizes. The copper bar support device adopts an upper and lower stacking structure, which is easy to operate when fixing the copper bar. Figure 5 As shown, the copper busbar support device 2 includes a body 21 and a hollow area 22, and a reserved space 5 is provided between the body 21 and the connection portion 11 of the copper busbar 1. The reserved space 5 facilitates the fixed connection between the copper busbar support device 2 and the copper busbar 1, and more specifically, is to facilitate the smooth locking of the screws 42 of the second fixing assembly 4, that is, the reserved space ensures that the copper busbar 1 is effectively fixed.

[0041] Furthermore, the hollow area 22 is located between the body 21 and the bottom wall 1011 of the box body 101. The design of multiple hollow areas 22 saves material costs and reduces the size of the device while ensuring that the copper bar support device can adequately support the copper bar.

[0042] The copper busbar 1 of this embodiment adopts a flat-bend structure, and a pair of copper busbars are used to connect two groups of batteries, wherein the connection portion of one copper busbar is connected to the positive terminal of the battery, and the connection portion of the other copper busbar is connected to the negative terminal of the battery. The structure is relatively simple, which not only saves the internal space of the box, but also reduces the cost. Further, the flat-bend structure includes a first straight portion 12, a bent portion 13, and a second straight portion 14, wherein the bent portion 13 is located between the first straight portion 12 and the second straight portion 14, wherein the length of the second straight portion 14 is 16-21 mm, wherein the angle between the bent portion 13 and the first straight portion 12 is 90-100°, and the angle between the bent portion 13 and the second straight portion 14 is 90-100°.

[0043] The copper bar support device 2 is used to support the copper bar 1 and is designed according to the structure of the copper bar. The device has a simple structure, adopts an upper and lower stacked structure, is small in size, is easy to operate when fixing the copper bar, and has sufficient wiring space reserved. While ensuring that the copper bar can be supported and fixed, the material cost is also low, meeting the diverse wiring needs of customers.
