Technical Field

[0001] The utility model relates to the technical field of power-type Pack boxes, and particularly relates to a Pack box convenient for assembly. Background Art

[0002] At present, the batteries on the market have a relatively complex structure and great assembly difficulty. When assembling the batteries, it is necessary to install battery cells, and all electrical components need to be assembled inside the box. It is impossible to install them in separate processes. Moreover, due to the large number of electrical components during the assembly process, the wire harnesses and wire terminals may be squeezed, which poses a great hidden danger, and the wiring is numerous, requiring a large amount of human resources and capital costs.

[0003] The invention patent with the publication number of CN110416459A discloses a multi-module combined PACK box body. In this invention patent, a base, a middle waist, and a cover plate are provided, and the internal space of the middle waist is divided into several accommodation grooves by partition plates. An accommodation cavity is also provided on the base, and the corresponding accommodation grooves and accommodation boxes communicate with each other up and down. The manufacturing process of this invention is simple and it has good heat dissipation at the same time. However, the structure of this installation method is not very stable and has great potential safety hazards.

[0004] Therefore, it is very necessary to develop a Pack box with a stable structure, convenient for assembly and stable structure, which can not only ensure that the Pack box is easy to install, but also ensure its stable and safe structure. Content of the Utility Model

[0005] Aiming at the deficiencies existing in the prior art, the utility model aims to provide a Pack box with a stable structure, convenient installation, and safety and reliability.

[0006] To achieve the above object, the utility model provides a Pack box convenient for assembly, which includes a detachable upper box body and a lower box body. An electrical installation plate is arranged between the upper box body and the lower box body. The electrical installation plate is fixedly installed on the upper box body. The lower box body is equipped with a battery cell module, and the battery cell module is connected to the electrical components on the electrical installation plate through a power interface and a collection interface respectively.

[0007] Based on the above, the utility model sets the detachable upper box body and lower box body structure. When installing the battery cell module, it is only necessary to connect the power interface and the collection interface to the electrical components of the electrical installation plate. Each process can be pre-assembled in advance, and there is no need for complex disassembly and assembly every time, making the installation of the battery cell module more convenient and efficient. It not only improves the installation efficiency but also ensures the product quality.

[0008] Further, one side of the upper box body is provided with a switch, a communication port, a circular meter, an antenna, a charging interface, and a discharging interface connected to the electrical installation plate.

[0009] Based on the above, the discharge interface, charging interface, switch, communication port, meter, and antenna are installed on the upper box body. Combining the detachable structure of the upper box body and the lower box body, it does not affect the stability of the overall electrical connection of the Pack box when the battery is disassembled.

[0010] Furthermore, transverse reinforcing ribs are provided on the four sides of the internal space of the lower box body.

[0011] Based on the above, the transverse reinforcing ribs play a role in strengthening the structure of the lower box body, improving the stability of the Pack box.

[0012] Furthermore, a fixing frame is fixedly installed inside the lower box body, and the fixing frame is used to fixedly install the battery cell module.

[0013] Based on the above, while the fixing frame is used to fixedly install the battery cell module, it can also strengthen the structure of the lower box body of the Pack box, making the installation structure inside the lower box body more stable and reliable.

[0014] Furthermore, the battery cell module is formed by welding a number of battery cells through aluminum sheets using a laser welding device. The battery cell module includes a first battery cell module, a second battery cell module, and a third battery cell module. Battery cell module fixing end plates are provided on both sides of the first battery cell module, the second battery cell module, and the third battery cell module, and the battery cell module fixing end plates are fixedly installed on the fixing frame through bolts.

[0015] Based on the above, disassembling the battery cell module into three parts facilitates the installation and disassembly of the battery cell module. At the same time, the battery template is fixedly installed inside the lower box body using the fixing frame.

[0016] Furthermore, an insulating Mylar sheet is provided below the electrical installation board.

[0017] Based on the above, the insulating property of the insulating Mylar sheet makes the electronic components safer during use, improving the safety of the product.

[0018] Furthermore, the upper box body is provided with a maintenance cover, and lifting rings are also provided on the surface of the upper box body.

[0019] Based on the above, when a fault occurs in the Pack box, the maintenance cover can be opened to repair the upper box body. When the Pack box needs to be lifted, the Pack box is lifted to the installation position for installation using the lifting rings.

[0020] To more clearly elaborate the above features of the present utility model and the purposes to be achieved, the following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments. Description of the Drawings
