[0002] A square-shell battery module is a device for storing and providing electrical energy, and is typically used in electric vehicles, energy storage systems, and other applications that require large-capacity batteries. They are typically composed of multiple battery cells, integrated in a housing or module, for ease of installation, management, and maintenance. During the battery pack production process, in order to ensure the stability of the battery module in the battery pack and the space utilization rate, the battery module needs to be compacted after buffer foam is affixed between the batteries in the module. After the battery module is boxed, the buffer foam naturally expands to saturate the space occupancy rate, thereby preventing the battery from shaking or colliding during movement. However, existing compacting devices often lack flexibility and are difficult to adapt to the battery module compacting requirements of battery packs of different specifications. Furthermore, the control of the compacting force places high demands on the operator and is not easy to control, resulting in low compacting flexibility of the battery module, which affects the compacting flexibility of the battery module.

When the battery seat 3 works with the base, it is convenient for the user to perform transverse pressing operation on the external battery module, avoiding the situation that the battery module processing operation is difficult to perform transverse pressing, thereby improving the convenience of battery module pressing.
[0031] Reference Figure 1-Figure 4 In a preferred embodiment, the transverse clamping mechanism includes a screw seat 4, which is fixedly connected to the front side of the top of the base plate 1, and a screw 5 is threadedly connected to the screw seat 4. A limit plate 6 is installed on the rear side of the screw 12. The top of the base plate 1 is fixedly connected to a limit seat 7 located on the rear side of the limit plate 6. A transverse guide rail 8 is fixedly connected to the top of the base plate 1. A transverse guide seat 9 rotatably connected to the screw 5 is installed on the top of the transverse guide rail 8. The battery tooling 10 is installed on the front side of the left side of the top of the base plate 1, and the longitudinal clamping mechanism is installed on the rear side of the left side of the top of the base plate 1. By rotating the screw 5 and cooperating with the screw seat 4, a thrust is applied to the limit plate 6, so that the limit plate 6 moves toward the limit seat 7, and the battery mold seat at the top of the electrical socket is pressed. At the same time, the transverse guide seat 9 follows the screw 5 in the transverse direction. Move to the top of the guide rail 8, guide and stabilize the limit plate 6 during the moving process, so that the limit plate 6 cooperates with the limit seat 7 to stably press the battery mold seat, and the longitudinal pressing mechanism includes a screw seat 11, a screw 12, a contact plate 13 and a contact seat 14. The screw seat 11 is installed on the rear side of the left side of the top of the base plate 1, and the screw 12 is threadedly connected to the inside of the screw seat 11. The contact plate 13 is installed on the right side of the screw 12, and the contact seat 14 is installed on the right side of the top of the base plate 1.

[0032] Reference Figure 1-Figure 4In a preferred embodiment, pressure sensors 15 are installed on the surfaces of the contact plate 13 and the limit plate 6, and the outer sides of the pressure sensors 15 are respectively connected to the screw 12 and the lead screw 5. The pressure sensor 15 is electrically connected to the pressure digital display 2 through a wire. When the screw 12 and the lead screw 5 are working, the pressure of the screw 12 and the lead screw 5 can be monitored, and the electrical signal can be displayed through the pressure digital display 2 so that the staff can understand the pressure value of the lead screw 5 when the screw 12 is working, thereby avoiding the situation where the pressure is difficult to control when the screw 12 and the lead screw 5 are working, thereby improving the control convenience of the screw 12 and the lead screw 5. A longitudinal guide rail 16 is installed on the left side of the top of the bottom plate 1, and a longitudinal guide seat 17 connected to the screw 12 is installed on the top of the longitudinal guide rail 16. When the screw 12 cooperates with the contact plate 13 to work, the trajectory of the screw 12 pushing the contact plate 13 can be guided and restricted, thereby avoiding the situation where the screw 12 shakes and is difficult to stably apply thrust to the contact plate 13 when working, thereby improving the working stability of the screw 12.
[0033] Reference Figure 1-Figure 3 In a preferred embodiment, by fixing adjustment seats 18 on both sides of the top of the bottom plate 1, the adjustment seats 18 are respectively located at the bottom of the screw seat 11 and the contact seat 14, so that when the contact seat 14 and the screw seat 11 are working, it is convenient for the user to adjust the contact seat 14 and the screw seat 11 according to the actual pressed battery mold seat, so that the screw 12 and the contact plate 13 can be better pressed and used according to the battery mold seat, avoiding the situation that the screw seat 11 and the contact seat 14 are difficult to adjust according to the battery mold seat when they are used, The use flexibility of the screw seat 11 and the contact seat 14 is improved, and the two sides of the top of the adjustment seat 18 are fixedly connected with sliding bars 19, and the tops of the sliding bars 19 are slidably connected to the bottoms of the screw seat 11 and the contact seat 14 respectively. When the adjustment seat 18 is used in conjunction with the screw seat 11 and the contact seat 14, the sliding connection and guiding work can be performed between the adjustment seat 18 and the screw seat 11 and the contact seat 14 to avoid the screw seat 11 and the contact seat 14 being separated from the adjustment seat 18 when adjusting, thereby improving the adjustment stability of the screw seat 11 and the contact seat 14.
[0034] Reference Figure 1-Figure 4In a preferred embodiment, by installing stabilizing seats 20 on both sides of the top of the adjustment seat 18, the inner sides of the stabilizing seats 20 are in contact with the outer sides of the screw seat 11 and the contact seat 14 respectively, so that when the adjustment seat 18 is used in conjunction with the screw seat 11 and the contact seat 14, a medium for stabilizing the screw seat 11 and the contact seat 14 after adjustment can be provided to the user, thereby avoiding the situation where the screw seat 11 and the contact seat 14 are difficult to work stably after adjustment, thereby improving the convenience of adjusting the screw seat 11 and the contact seat 14, a connecting plate 21 is installed on the top of the contact plate 13, and connecting frames 22 are installed on both sides of the left side of the battery tooling 10, which can provide the battery tooling 10 with a medium for installation and connection with the contact plate 13 when the battery tooling 10 is used in conjunction with the contact plate 13, thereby avoiding the situation where the battery tooling 10 is difficult to connect with the contact plate 13 when in use, thereby improving the convenience of battery installation and use.
[0035] Specifically, the working process or working principle of the square shell battery module clamping mechanism is as follows: when in use, the battery fixtures 10 of different sizes are installed according to the battery modules to be clamped according to actual needs, so that the contact plate 13 is switched to a mode suitable for different battery module arrangements. During the installation of the battery fixture 10, the mobile battery fixture 10 drives the connecting frame 22 to plug into the connecting frame 22 on the top of the contact plate 13, so that the battery fixture 10 can be connected to the contact plate 13. Subsequently, according to the actual clamping position and needs of the battery module, the screw seat 11 and the contact seat 14 are moved, and the positions of the screw 12 and the contact plate 13 are adjusted so that the contact plate 13 can better apply force to the battery module for clamping work. , the slide bar 19 performs sliding guiding work between the screw seat 11 and the contact seat 14 and the adjustment seat 18. After the screw seat 11 and the contact seat 14 are adjusted, the stable seat 20 and the adjustment seat 18 are installed and stabilized by bolts, and it is ensured that the stable seat 20 and the adjusted screw seat 11 and the contact seat 14 apply a limiting stabilizing force, so that the adjusted screw seat 11 and the contact seat 14 are stabilized on the top of the adjustment seat 18. Then, the battery module that needs to be pressed is placed on the top of the electrical socket, and the screw rod 5 is first rotated to cooperate with the screw seat 4 to apply the actual thrust to the limit plate 6, so that the limit plate 6 cooperates with the limit seat 7 to perform horizontal pressing work on the battery work on the top of the battery seat 3, and then the screw 12 is rotated to cooperate with the screw seat 11 to press the contact plate 13 and The battery fixture 10 applies a thrust, so that the contact plate 13 cooperates with the contact seat 14 to perform longitudinal compression on the battery mold seat on the top of the battery seat 3, so that the battery module is fully compressed on the top of the battery seat 3. Since the screw seat 11 is a floating base, when the screw 12 is rotated to compress the battery, the spring is compressed, and the screw seat 11 moves backward, and the spring force is cleverly used to compress the battery module, which solves the problem that the operator is not easy to control the force directly applied to the battery module by rotating the screw 5, reduces the difficulty of operation, and improves the safety of the equipment. In this process, the transverse guide seat 9 and the longitudinal guide seat 17 move with the screw 5 and the screw 12 respectively, and guide and stabilize the screw 5 and the screw 12 during the working process. The screw rod 5 and the screw rod 12 ensure the stability of the thrust applied to the limit plate 6 and the contact plate 13. At the same time, the pressure sensor 15 monitors the pressure value of the limit plate 6 and the contact plate 13 in real time during the process of pressing the battery module, and transmits the signal to the pressure digital display 2 for display on the pressure digital display 2, so that the actual pressure when the contact plate 13 and the limit plate 6 press the battery module can be understood, and the pressing force of the contact plate 13 and the limit plate 6 can be adjusted, so that the staff can better adjust the pressing force of the contact plate 13 and the limit plate 6 to press the battery module, so that the operator can accurately control the pressing force to prevent damage to the battery module, reduce the difficulty of operation, and improve the safety of the equipment.
[0036] It should be noted that the pressure digital display 2 and the pressure sensor 15 are both devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
