DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] In view of the fact that in the design process of existing battery packs, in order to increase the energy volume density of a single pack, the internal space of the battery pack is mostly left relatively small, which causes inconvenience in assembling the battery pack module, a placement tool suitable for the mobile charging pile battery pack module is specially designed. The overall structure of the placement tool is as follows: Figure 1As shown, the main structural components include: a tooling frame, a side plate 1-3, a support seat 1-4, a movable shaft assembly, a No. 1 bottom plate 1-5, a lifting lug 1-9 and a pin 1-14;

[0025] The tooling frame serves as a structural support and is composed of welded cross beams 1-1 and longitudinal beams 1-2 that are staggered.

[0026] The No. 1 base plate 1-5 is arranged based on the tooling frame. The No. 1 base plate 1-5 is respectively distributed at the two ends below the tooling frame. The No. 1 base plate 1-5 provides an installation plane and a location for the arrangement of the support seat 1-4.

[0027] Support seats 1-4 are mainly used for setting the movable shaft assembly, such as Figure 2 As shown, the movable shaft assembly includes a movable shaft 1-12 and a shaft sleeve 1-13; the movable shaft 1-12 is installed in the shaft sleeve 1-13, and the shaft sleeve 1-13 is matched and installed in the shaft hole of the support seat 1-4, thereby realizing the installation of the movable shaft assembly at the support seat 1-4.

[0028] The output end of the movable shaft assembly is connected with the side plate 1-3, and specifically, the conveying end of the movable shaft 1-12 is locked and connected with the side plate 1-3 through a fixing nut 1-10, and the sliding movement of the movable shaft can synchronously drive the side plate 1-3 to move.

[0029] The side panels 1-3 are symmetrically distributed on both sides of the tooling frame, and the side panels 1-3 on both sides jointly form a module clamping space. In order to make the side panels 1-3 and the battery pack module cooperate more reliably, pins 1-14 are fixed on the side panels 1-3, and the pins 1-4 are adapted to the pin fixing holes 5 on the end panels 4 of the module 2 (such as Figure 4 In addition, the movable shaft connected to one side of the side plate needs to be limited, while the other side does not need to be limited, so as to achieve the sliding of one side of the side plate, and to achieve the installation and release of the pins 1-14 on the side plate and the pin fixing holes 5 on the end plate 4 of the module 2, so as to form the clamping or placement of the module 2.

[0030] The limit setting of the side plate 1-3 on one side can be realized by the limit bracket 1-11 structure, and mounting holes for installing the limit bracket 1-11 are respectively provided on the movable shaft 1-12 and the support seat 1-4. Figure 1 As shown, one side panel 1-3 is connected with two sets of movable shaft assemblies. Therefore, by installing the limiting bracket 1-11 between any one of the movable shaft assemblies and the support seat 1-4, the limiting of one side panel 1-3 can be achieved.

[0031] In order to meet the hoisting use of the placement tooling, and to facilitate the use of ropes or hook tools to lift or place the module later, lifting ears 1-9 are provided, and lifting ear fixing plates 1-8 are symmetrically fixed on the tooling frame, and then the lifting ears 1-9 for lifting are installed and fixed through the lifting ear fixing plates 1-8.

[0032] Preferably, a second base plate 1-7 of the same thickness as the first fixed plate 1-5 is fixed at the middle position below the tooling frame, and the silicone plate 1-6 is fixed to the base plate by bolt fasteners. After fixation, the bolt fasteners are insulated and protected to ensure that during the process of hoisting the module, metal parts are prevented from scratching the module and causing internal short circuit.

[0033] Furthermore, the assembly process of the placement tooling of the mobile charging pile battery pack module disclosed in the utility model is introduced to facilitate a better understanding of the structural setting of the placement tooling:

[0034] First, the cross beam 1-1 and the longitudinal beam 1-2 are placed in staggered positions to form the tooling frame foundation, and the relevant transition positions are spot welded. During the spot welding process, the horizontal and vertical surfaces of the frame shape are checked. After the tooling frame is welded, the No. 1 bottom plate 1-5, the No. 2 bottom plate 1-7, and the ear fixing plate 1-8 are spot welded and fixed according to the positions of the relevant components, so that the overall structure of the weldment is formed. After the overall spot welding of the weldment is completed, the transition positions of the relevant welding components are reinforced and welded to ensure the overall welding strength of the frame.

[0035] Secondly, on the basis of obtaining the skeleton shape by welding, the support seat 1-4 and the silicone plate 1-6 are bolted and connected by bolt fasteners to ensure the firmness of the installation parts; the bolt fasteners are insulated and protected.

[0036] On the basis of the above, the shaft holes of the bushing 1-13 and the support seat 1-4 are matched and installed, and then the shaft holes of the movable shaft 1-12 and the bushing 1-13 are matched. After the installation of the movable shaft is completed, the side panel 1-3 is installed. By matching the mounting holes of the side panel 1-3 with the hole positions of the movable shaft, the side panel 1-3 and the movable shaft are fixed by the fixing nut 1-10. Then, the limiting bracket 1-11 is limitedly matched with the movable shaft, bushing and support seat with preset limiting mounting holes to form a fixed structure, so as to achieve the limiting of one side panel, while the limiting operation is not performed on the other side panel, so as to achieve the sliding of this side panel, which is used for the pins 1-14 and Figure 4 The pin fixing holes 5 on the end plates 4 of the module 2 are squeezed or released, thereby clamping or placing the module.

[0037] On the basis of the above, the lifting lugs 1-9 are installed on the lifting lug fixing plate 1-8, so that the entire tooling can be lifted or placed by a rope locking tool or a hook tool.

[0038] At this point, the assembly of the battery pack module placement tooling for the mobile charging pile is completed.

[0039] For the use of the new placement tool, such as Figure 3 As shown, it shows the situation when it is applied to a battery pack. The figure shows some key components of the battery pack module installation, including module 2, box weldment 3, inter-module connection bar 6, total positive connection bar 7, high-voltage plug-in 8, communication plug-in 9, BMS component 10, explosion-proof valve 11, aerosol bracket 12, aerosol 13, total negative connection bar 14;

[0040] First, assemble the basic components of the battery pack, including the box weldment, high-voltage plug-in, communication plug-in, and explosion-proof valve. After the installation is completed, use the new placement tool to clamp the module 2, and align the pins on the side plate (non-sliding) on ​​one side of the limited bracket with the pin fixing holes 5 on the module end plate. Then, install the pins on the side plate (sliding) on ​​the other side into the pin fixing holes 5 on the module end plate through the sliding side plate.

[0041] After the assembly of the placement tool and the module is completed, the module is hoisted by ropes and placed in the corresponding fixed module position in the box, and the module fixing holes 15 of the module end plate and the module fixing holes 16 of the mounting beam are threadedly connected and fixed by bolt fasteners to complete the installation of the module. After the module is placed, the pins on the side plate (slidable side) can be released to realize the disassembly of the placement tool.

[0042] The installation of other modules is achieved according to the clamping and releasing method of the above modules.

[0043] After all modules are placed, the fire aerosol bracket and BMS components are fixed by bolt fasteners. After the installation is completed, the inter-module connecting bars, the total positive connecting bars, and the total negative connecting bars are fixed to complete the assembly of the box assembly.

[0044] In summary, the placement tooling for the mobile charging pile battery pack module provided by the utility model completes the placement of the module by lifting and clamping, thereby solving the problem that the battery pack module cannot be conveniently assembled in the existing small space, thereby avoiding the problem of scratches on the module cells or crooked placement of the module holes during the placement of the battery pack module, thereby improving the installation efficiency of the module placement battery pack and the assembly efficiency of the entire battery pack.

[0045] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
