DETAILED DESCRIPTION

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The utility model discloses a clamping and placing tool suitable for a battery pack module. The structure of the clamping and placing tool is as follows: Figure 1 and Figure 2 As shown, the main structural components include: a load-bearing beam 1-1, a lifting ring assembly, a side plate 1-7, a retractable connecting arm 1-9, a No. 1 screw assembly 1-2 and a No. 2 screw assembly 1-6;

[0029] The load-bearing beam 1-1 is used as a basic framework, and is welded together by a square tube 1-1a, an upper welding bracket 1-1b, and a lower welding bracket 1-1c. The upper welding bracket 1-1b is welded and fixed above the middle position of the square tube 1-1a, and the upper welding bracket 1-1b is subsequently used for the installation of the lifting ring assembly;

[0030] There are two lower welding brackets 1-1c in total. The two lower welding brackets 1-1c are welded and fixed below the two ends of the square tube 1-1a. The two lower welding brackets 1-1c are symmetrically distributed. The lower welding brackets 1-1c are subsequently used for the installation of the side panels 1-7, so that the side panels on both sides can form a space for module clamping.

[0031] The lifting ring assembly is used for lifting of the clamping and placing tooling. It is assembled to the upper welding bracket 1-1b through the No. 1 screw assembly 1-2. An up and down movable waist hole 1-10 is opened on the welding bracket 1-1b. The No. 1 screw assembly 1-2 is installed in the up and down movable waist hole 1-10 to meet the up and down sliding stroke of the No. 1 screw assembly 1-2 during the lifting process of the lifting ring assembly.

[0032] The lifting ring assembly specifically includes a lifting ring fixing plate 1-4, a lifting ring 1-5 and a fixing nut 1-3; the lifting ring fixing plate 1-4 is provided with a through hole for the screw of the first screw assembly 1-2 to penetrate, so as to achieve synchronous movement of the lifting ring fixing plate 1-4 and the first screw assembly 1-2. The lifting ring 1-5 is locked and connected to the top of the lifting ring fixing plate 1-4 through the fixing nut 1-3.

[0033] As for the side plates 1-7, there are two symmetrically distributed on both sides of the load-bearing beam 1-1, which are used to clamp the battery pack module, and the side plates 1-7 are fixed with pins 1-8, and the pins 1-8 are adapted to the pin fixing holes 16 on the end plates 15 of the module 3 (such as Figure 4 shown).

[0034] The side plate 1-7 is specifically assembled to the lower welding bracket 1-1c through the No. 2 screw assembly 1-6. A lateral movable waist hole 1-11 is provided on the lower welding bracket 1-1c, and the No. 2 screw assembly 1-6 is installed in the lateral movable waist hole 1-11, so that the side plate 1-7 can slide in the horizontal direction. Preferably, the top of the side plate 1-7 is folded upward to form a side fixing ear 1-12, and a through hole for the No. 2 screw assembly 1-6 to penetrate is provided on the side fixing ear 1-12, so that the side plate 1-7 is assembled and set on the lower welding bracket 1-1c by using the side fixing ear.

[0035] In order to enable the lifting and lowering actions of the lifting ring assembly to link the horizontal movement of the side plate 1-7 and realize the clamping and opening actions of the side plate, a retractable connecting arm 1-9 is provided for connection. One end of the retractable connecting arm 1-9 is hingedly connected to the first screw assembly 1-2, and the other end is hingedly connected to the second screw assembly 1-6.

[0036] The retractable connecting arm 1-9 specifically includes an outer connecting rod 1-9a and an inner connecting rod 1-9b; wherein, the outer connecting rod 1-9a and the inner connecting rod 1-9b are hingedly connected to the No. 1 screw assembly 1-2 at one end; the outer connecting rod 1-9a is hingedly connected to the No. 2 screw assembly located on one side of the load-bearing beam 1-1 at the other end; the inner connecting rod 1-9b is hingedly connected to the No. 2 screw assembly located on the other side of the load-bearing beam 1-1 at the other end.

[0037] Furthermore, the assembly process of the clamping and placement tooling for the battery pack module disclosed in the present invention is introduced to facilitate the understanding of its structural arrangement.

[0038] First, the square tube 1-1a, the upper welding bracket 1-1b, and the lower welding bracket 1-1c are spot welded to form the basic framework of the load-bearing beam 1-1. During the spot welding process, the horizontal and vertical planes of the framework are checked to prevent the upper welding bracket and the lower welding bracket from being skewed during the welding process, which will affect the installation of the outer connecting rod 1-9a and the inner connecting rod 1-9b in the later stage. After the spot welding is completed, the welds of the relevant transition positions are reinforced to ensure the bearing strength of the load-bearing beam.

[0039] On the basis of welding to obtain the load-bearing beam, the lifting ring 1-5 is fixed to the lifting ring fixing plate 1-4 by fixing the nut 1-3 to ensure the reliability of the lifting ring during the lifting process; then the lifting ring fixing plate is assembled with the upper welding bracket of the load-bearing beam by the screw of the No. 1 screw assembly 1-2, and the screw of the No. 1 screw assembly is used to match the shaft holes of the outer connecting rod and the inner connecting rod, and then the nut of the No. 1 screw assembly is locked. When the lifting ring 1-5 is lifted or lowered by a rope, the vertical upward and downward moving waist hole 1-10 opened on the upper welding bracket can meet the lifting or lowering requirements of the lifting ring fixing plate.

[0040] On the basis of the above assembly, the side plate 1-7 is assembled with the lower welding bracket using the screw of the No. 2 screw assembly 1-6, and the screw of the No. 2 screw assembly is used to match the shaft holes of the outer connecting rod and the inner connecting rod, and then the nut of the No. 2 screw assembly is locked to complete the assembly of the clamping and placing tooling. The outer connecting rod and the inner connecting rod form a contraction connecting arm to achieve the transmission effect. The horizontal lateral movement waist hole 1-11 opened on the lower welding bracket can meet the needs of the side plate contraction, opening and closing movement, thereby realizing the installation and release of the pins on the side plate to the module end plate.

[0041] After the clamping and placing tooling is assembled by the above assembly method, it is applied to the assembly of the battery pack module. Figure 3 and Figure 4 As shown, an assembly of a battery pack module and its key components are listed, including an inter-module connection bar 2, a module 3, a box weldment 4, a communication plug-in 5, a high-voltage plug-in 6, a total positive connection bar 7, a BMS component 8, an explosion-proof valve 9, an aerosol bracket 10, an aerosol 11, and a total negative connection bar 12;

[0042] First, assemble the basic components of the battery pack box, including the box weldments, high-voltage plug-ins, communication plug-ins, and explosion-proof valves. After the installation is completed, use the module lifting tool to lift the lifting ring fixing plate. During the lifting process, the side plate is retracted by sliding the inner and outer connecting rods upward, so that the pins on the side plate are installed and matched with the pin fixing holes 16 on the module end plate 15, thereby realizing the module lifting.

[0043] When the module is lifted to the appropriate position for the battery pack installation spacing, the lifting ring fixing plate is lowered, thereby driving the inner and outer connecting rods to slide downward, realizing the opening of the side plate, clamping and placing the pins on the side plate of the tooling and the module end plate pin fixing holes to release, thereby releasing the current module, and then threading and fixing the module fixing holes 14 of the module end plate with the module fixing holes 13 of the mounting beam through bolt fasteners. Other modules are installed according to the above clamping and releasing methods.

[0044] After all modules are placed, they are fixed with bolts, fasteners, fire aerosols and BMS components. 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.

[0045] In summary, the clamping and placement tooling suitable for the battery pack module disclosed in the utility model utilizes an inner and outer connecting rod type retractable connecting arm structure for transmission, and is combined with the lifting and lowering operations of the clamping and placement tooling to realize the clamping and opening actions of the side panels. Since the module is placed in a fixed spacing space in the battery pack using the module clamping and placement tooling, the accuracy of the module placement position can be improved. While reducing the probability of scratches and wear on the protective layer diaphragm of the outer battery cell of the module, the problem of crooked placement of the existing module hole position is solved, thereby improving the installation efficiency of the module clamping and placement battery pack module and the assembly efficiency of the entire battery pack.

[0046] 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.
