[0053] It should be noted that one battery cell unit 210 is composed of a plurality of battery cells. Therefore, during the installation process, with the inner wall of the bottom plate 110 as the placement plane, the battery cells are installed along a third direction, so that while the bottom plate 110 can provide support for the battery cell unit 210, it can also ensure the flatness of the battery cell installation.

[0054] Furthermore, please refer to Figures 1 - 6 , Figure 3 is Figure 2 the cross-sectional view at A-A in Figure 4 is the structural schematic diagram of the side plate 120 provided by the embodiment of the present utility model; Figure 5Schematic diagram of the partition 130 provided by the embodiment of the present utility model; Figure 6 Schematic diagram of the insertion plate 140 provided by the embodiment of the present utility model.

Thus, during subsequent maintenance, it is convenient for the staff to disassemble the insertion plate 140 and the partition 130, so as to facilitate the disassembly of the battery cells in the accommodating cavity 101.

[0057] It should be noted that the opening directions of the first clamping grooves 131 and the second clamping grooves 141 in this embodiment are opposite. The number of the first clamping grooves 131 is equal to the number of the second clamping grooves 141 and they correspond one by one, and the axis of each first clamping groove 131 coincides with the axis of the corresponding second clamping groove 141.

[0058] In other embodiments, the bottom plate 110, the side plates 120, the partition 130 and the insertion plate 140 can also be fixedly connected together by welding, so as to improve the structural strength of the housing 100. The operator can choose different connection modes according to the actual situation.

[0062] Please refer to Figures 1 - 7 , Figure 7 which is an exploded view of the battery module 200 provided by the embodiment of the present utility model.

Each middle accommodation cavity 101 is jointly enclosed by two partition plates 130 and two insertion plates 140. Therefore, the battery cell unit 210 accommodated in the middle accommodation cavity 101 is attached to the side plate 120 and the partition plate 130.

[0064] It can be understood that by providing a plurality of partition plates 130 and a plurality of insertion plates 140 and making the battery cell unit 210 attached to the partition plates 130 and the insertion plates 140, the contact surface between the battery cell unit 210 and the housing 100 is increased, so that the heat of the battery cell unit 210 can be transferred to the housing 100, thereby improving the heat dissipation efficiency of the battery module 200.

[0065] It should be noted that during the installation of the battery module 200, there is a certain gap between the battery cell unit 210 and the housing 100.

The battery module 200 also includes an integrated PCB board 220, which is connected to one end of the two side panels 120 away from the bottom plate 110 and a plurality of battery cell units 210, thereby replacing the series-parallel reflux of the battery cells in the prior art and the collection function of the FPC (Flexible Printed Circuit) to distribute current and voltage. This embodiment utilizes the integrated PCB board 220, which can improve the heat dissipation efficiency, reduce costs, and make the structure simpler.

[0067] It should be noted that the integrated PCB board 220 is mainly used for connecting and fixing electronic components. The integrated PCB board 220 forms a wiring structure of the electronic circuit by printing a conductive copper line on an insulating substrate, so that the electronic components can be electrically connected in a predetermined manner. FPC is a circuit board with high flexibility and bendability, and has the characteristics of high wiring density, light weight, thin thickness, and good bendability. Among them, the heat dissipation effect of the integrated PCB board 220 is stronger than that of FPC, and the cost is lower.

[0068] According to the above structure, the integrated PCB board 220 includes a body 221, a positive plug-in 222, a negative plug-in 223 and a low-voltage collection plug-in 224. The positive plug-in 222, the negative plug-in 223 and the low-voltage collection plug-in 224 are arranged on the body 221, wherein the positive plug-in 222 and the negative plug-in 223 are connected to external electronic components to form a complete circuit; the low-voltage collection plug-in 224 is used to collect and detect low-voltage signals to ensure the stability of the battery pack 300 during operation, avoid short circuits and other phenomena, and thus ensure safety.

[0069] Please refer to Figures 1 - 11 , Figure 9 An exploded schematic diagram of a battery pack 300 provided in an embodiment of the utility model from a first viewing angle; Figure 10 A schematic diagram of the structure of a housing 310 provided in an embodiment of the utility model; Figure 11 This is a schematic structural diagram of a battery pack 300 provided in an embodiment of the present invention from a second viewing angle.

[0070] The embodiment of the utility model provides a battery pack 300, which includes a shell 310 and a battery module 200, wherein the battery module 200 is disposed in the shell 310.

[0071] Specifically, a plurality of second mounting grooves 123 are arranged at intervals in the third direction, and a plurality of first mounting grooves 121 and a plurality of second mounting grooves 123 are arranged alternately in the third direction. Combining the foregoing content, it can be understood that the clamping holes 122 are opened in the second mounting grooves 123.

[0072] It should be noted that the opening directions of the first mounting grooves 121 and the second mounting grooves 123 are opposite.

[0073] The housing 310 of the battery pack 300 is provided with reinforcing ribs 311 to improve the structural strength and stability, thereby improving the protection effect on the battery module 200 and ensuring the safety of the battery pack 300. And, in order to avoid the housing 100 of the battery module 200 from obstructing the housing 310 during the installation process, the second mounting grooves 123 are provided to avoid the reinforcing ribs 311.

[0074] It should be noted that in this embodiment, the numbers and shapes of the second mounting grooves 123 provided on the two side plates 120 are not the same.

In other embodiments, the staff can adjust the numbers and shapes of the second mounting grooves 123 according to the actual situation.

[0075] In this embodiment, the number of the second mounting grooves 123 provided on one of the two side plates 120 is less than the number of the second mounting grooves 123 provided on the other side plate 120. In the third direction of the side plate 120 with fewer second mounting grooves 123, there is a certain distance between the second mounting groove 123 and the end plate of the side plate 120, so that when the battery module 200 is installed into the housing 310, there is a certain space between the side plate 120 and the housing 310 to install structures such as electronic components.

[0076] Furthermore, the battery pack 300 further includes a thermal conductive adhesive layer 320, and the thermal conductive adhesive layer 320 is attached to the inner wall of the housing 310 and the side of the integrated PCB board 220 facing away from the plurality of battery cell units 210; the thermal conductive adhesive layer 320 is used to transfer the heat of the integrated PCB board 220 to the housing 310. Thus, the battery pack 300 can fix the integrated PCB board 220 and the housing 310 through the adhesiveness of the thermal conductive adhesive layer 320; and improve the heat dissipation efficiency of the battery pack 300 through the thermal conductivity.

[0077] According to the above structural settings, please refer to Figures 1 - 11, the battery pack 300 further includes a pressure plate 330 and a limit support plate 340.

[0078] During the installation process, the position of the battery module 200 can be determined through the limit support plate 340, that is, the bottom plate 110 is connected to the limit support plate 340. After the battery module 200 is installed into the housing 310, the pressure plate 330 is set to press the battery module 200, and the pressure plate 330 is connected to the housing 310 and the battery module 200, so as to fix the battery module 200 and prevent the battery module 200 from shaking.

[0079] In summary, the housing 100 is provided with a bottom plate 110, and the bottom plate 110 is used to support the battery cell unit 210, so that the battery cell unit 210 can be placed on the bottom plate 110 to ensure the flatness of the installation of the battery cell unit 210. The housing 100 improves the structural strength of the housing 100 by providing two side plates 120, a plurality of partition plates 130 and a plurality of insertion plates 140; and through the connection relationship between the two side plates 120, the plurality of partition plates 130 and the plurality of insertion plates 140, they jointly enclose a plurality of accommodation cavities 101 for accommodating the battery cell unit 210, so as to protect the battery cell unit 210 by using the side plates 120, the partition plates 130 and the insertion plates 140, thereby avoiding damage to the battery cell unit 210 and improving the safety of the battery pack 300.

[0080] The battery module 200 includes a plurality of battery cells and a housing 100. A plurality of battery cell units 210 are all attached to at least one partition plate 130 and at least one insertion plate 140; some battery cell units 210 are attached to one side plate 120, so that the contact area between the battery cell unit 210 and the housing 100 is increased, thereby transferring the heat of the battery cell unit 210 to the housing 100, and further improving the heat dissipation effect of the battery cell unit 210.

[0081] The battery pack 300 includes a housing 310 and a battery module 200.
