Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery production technology, specifically to a battery module cover plate mounting device. Background Technology
[0002] A battery module is a unit assembled from multiple battery cells. Its main function is to increase the voltage and energy storage capacity of the battery system by connecting multiple battery cells to meet the power needs of different applications. It is usually composed of several battery cells, connectors, battery management system and casing, etc. The casing is divided into structures such as cover and cover plate. Therefore, special mounting devices are usually used when encapsulating the casing.
[0003] However, when installing and sealing existing battery modules with cover plates, the battery modules are usually placed on the fixture platform of the device. After the battery module is placed, the fixture platform needs to be adjusted to ensure that the fixture clamps the battery module and fix it to the device. During the fixture adjustment process, the fixed position of the battery module is prone to misalignment with the position of the cover plate, which affects the accuracy of the cover plate installation. In addition, traditional battery module cover plates are usually installed by directly covering the cover plate after the battery module is fixed and then pressing it with a hydraulic system. When the battery module is subjected to excessive pressure due to improper operation, it is easy for the battery module to be damaged or even explode. Since the battery module has no explosion-proof mechanism, the shock wave generated by the explosion can directly cause serious injury to the operators around the device, resulting in a significant safety hazard during the installation of battery module cover plates. Utility Model Content
[0004] The purpose of this utility model is to provide a battery module cover mounting device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery module cover plate mounting device, including a base box, a top frame fixedly connected to the top of the base box, a hydraulic cylinder mounted on the top of the top frame, a pressure sensor mounted on one side of the hydraulic cylinder, a piston rod provided at the output end of the hydraulic cylinder, a pressure plate mounted at the bottom end of the piston rod, a top opening in the middle of the top of the base box, deformation strips provided on both sides of the inner wall of the top opening, a cover plate provided on the top of the deformation strips, a sliding table provided on the front of the base box, side plates fixedly connected to both side walls of the sliding table, a groove provided on the inner side of the side plate, a battery module placed inside the groove, and an explosion-proof plate embedded inside the base box.
[0006] Preferably, a controller is installed on one side wall of the top frame, the pressure sensor is electrically connected to the output pipeline of the hydraulic cylinder, and the controller is electrically connected to the pressure sensor.
[0007] Preferably, a pad is fixedly connected to the bottom end of the pressure plate, and the pressure plate is movably embedded in the top opening through a piston rod.

[0009] Preferably, a drive motor is installed on the back of the base box, and the output end of the drive motor is fixedly connected to the back of the slide table.
[0010] Preferably, a side opening is provided in the center of the front of the base box, the slide is slidably connected to the side opening via a drive motor, and the battery module is slidably connected to the base box via the slide.
[0011] Preferably, the cover plate is connected to the battery module through a top opening.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This battery module cover mounting device, through a top opening, notch, deformation strip, side plate, and groove, allows the cover to be placed on the device at the position directly above the battery module. At the same time, the side plate and groove allow the battery module to be placed directly on the device without the need for adjusting clamps to fix the battery module. This enables the battery module and cover to be quickly and accurately aligned, thereby reducing the probability of misalignment between the battery module and the cover and improving the accuracy of the cover during installation.
[0014] 2. This battery module cover installation device, through pressure sensors and pads, prevents excessive pressure on the battery module and cover during installation. Furthermore, the relatively enclosed structure formed by the explosion-proof plate and sliding table within the base box ensures that if the battery module explodes during installation, the shock wave generated can be blocked by the explosion-proof plate, reducing the probability of injury to personnel around the device and minimizing safety hazards during battery module installation.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] like Figures 1 to 4As shown, the battery module cover mounting device in this embodiment includes a base box 6. A top frame 1 is fixedly connected to the top of the base box 6. A hydraulic cylinder 2 is installed on the top of the top frame 1. A pressure sensor 3 is installed on one side of the hydraulic cylinder 2. A piston rod 15 is provided at the output end of the hydraulic cylinder 2. A pressure plate 4 is installed at the bottom end of the piston rod 15. A top opening 7 is provided in the middle of the top of the base box 6. Deformation strips 9 are provided on both sides of the inner wall of the top opening 7. A cover plate 14 is provided on the top of the deformation strips 9. A slide table 11 is provided on the front of the base box 6. Side plates 16 are fixedly connected to both sides of the slide table 11. A groove 17 is provided on the inner side of the side plate 16. A battery module 13 is placed inside the groove 17. An explosion-proof plate 18 is embedded inside the base box 6.
[0024] Specifically, the base box 6 has no other openings besides the side opening on the front and the top opening 7 on the top, making the interior of the base box 6 a well-sealed structure. This helps to block the shock wave generated by the battery module 13 during combustion and explosion, thereby reducing personal injury to nearby operators. The top frame 1 allows the pressure plate 4 for installing the cover plate 14 to be raised to a suitable position so that the cover plate 14 can be placed into the top opening 7 of the base box 6. The hydraulic cylinder 2 drives the pressure plate 4 to press the cover plate 14 downwards in the top opening 7 using hydraulic force, so that the cover plate 14 can be installed on top of the battery module 13 placed in the base box 6, thereby achieving the installation of the battery module. The installation of cover plate 14 involves a hollow silicone deformation strip 9 protruding from both sides of the top opening 7, which supports the cover plate 14 placed inside the top opening 7, facilitating the subsequent installation of cover plate 14 by pressure plate 4. The slide table 11 slides out from the bottom box 6, making it easy to remove the battery module 13 with cover plate 14 installed. The groove 17 limits the battery module 13 placed on the slide table 11, avoiding the need to use clamps or other auxiliary tools to fix the battery module 13, and eliminating the need to adjust the clamps, making it easier for users to operate. The explosion-proof plate 18 absorbs the shock wave generated when the battery module 13 explodes, reducing the damage caused by the explosion.
[0025] Furthermore, a controller 8 is installed on one side wall of the top frame 1. The pressure sensor 3 is electrically connected to the output pipeline of the hydraulic cylinder 2. The controller 8 is electrically connected to the pressure sensor 3. The pressure sensor 3 can detect the pressure output by the hydraulic cylinder 2, so that the force output by the hydraulic cylinder 2 is not too large. At the same time, when the output pressure is too large, it can be controlled by the controller 8 to reduce the probability of damage and explosion of the battery module 13 due to excessive extrusion pressure.
[0026] Furthermore, a pad 5 is fixedly connected to the bottom end of the pressure plate 4. The pressure plate 4 is movably embedded in the top opening 7 through the piston rod 15. The size of the pressure plate 4 is adapted to the size of the top opening 7, so that the force on the cover plate 14 is more uniform when it is pushed down by the pressure plate 4, thereby reducing the probability of damage to the cover plate 14 during installation.
[0027] Furthermore, a notch 10 is provided on the front of the top opening 7. The cover plate 14 is slidably connected to the top opening 7 through the notch 10. The function of the notch 10 is to allow the cover plate 14 to be pushed into the top opening 7 in the horizontal direction, so that the user can place the cover plate 14 into the top opening 7 of the bottom box 6. At the same time, it is more conducive to aligning the cover plate 14 with the battery module 13 in the bottom box 6.
[0028] Furthermore, a drive motor 12 is installed on the back of the base box 6. The output end of the drive motor 12 is fixedly connected to the back of the slide table 11. The function of the drive motor 12 is to apply force to the slide table 11, so that the slide table 11 can slide in and out of the front of the base box 6, thereby facilitating the slide table 11 to drive the battery module 13 to slide in and out, making it easier for the user to operate.
[0029] Furthermore, a side opening is provided in the center of the front of the base box 6. The slide table 11 is slidably connected to the side opening through the drive motor 12. The battery module 13 is slidably connected to the base box 6 through the slide table 11. The function of the side opening is to allow the slide table 11 to slide in and out from the front of the base box 6 under the action of the drive motor 12, thereby facilitating the placement of the battery module 13 in the device and facilitating the removal of the battery module 13.
[0030] Furthermore, the cover plate 14 is connected to the battery module 13 through the top opening 7. The cover plate 14 can be pushed onto the top of the battery module 13 on the slide table 11 under the action of the pressure plate 4, thereby realizing the installation of the cover plate 14 of the battery module 13. When the pressure plate 4 is pressed down, the top opening 7 of the bottom box 6 will be closed by the pressure plate 4, and the side opening on the front of the bottom box 6 will be closed by the slide table 11, so that the interior of the bottom box 6 can become a closed space.
[0031] The usage method of this embodiment is as follows: Before using the battery module 13 cover plate 14 installation device, the device needs to be connected to an external power supply, and then the drive motor 12 is started, so that the drive motor 12 pushes the slide table 11 out from the front of the bottom box 6. Then, the battery module 13 to be packaged can be placed in the groove 17 of the slide table 11. Then, the drive motor 12 will drive the slide table 11 back into the bottom box 6 until the front of the slide table 11 coincides with the front of the bottom box 6. The top of the battery module 13 will be directly below the top opening 7. Then, the cover plate 14 can be pushed in from the notch 10, so that the cover plate 14 slides into the top opening 7 along the top of the deformation strip 9. When the cover plate 14 can no longer be pushed in along the notch 10, the hydraulic cylinder 2 will be activated. The piston rod 15 pushes the pressure plate 4 towards the cover plate 14 placed in the top opening 7, causing the cover plate 14 to be pressed downwards to the top of the battery module 13. During the downward push of the cover plate 14, the deformation strip 9 will be squeezed and deformed until the cover plate 14 is pressed tightly on the top of the battery module 13, at which point the deformation strip 9 will return to its original shape, thus completing the installation of the cover plate 14 of the battery module 13. At the same time as the cover plate 14 is installed, the pressure sensor 3 will detect the force output by the hydraulic cylinder 2. If the output force is detected to be too large, the controller 8 will adjust the force output by the hydraulic cylinder 2, so that when the cover plate 14 is pressed down to the top of the battery module 13, it is not easy for it to be damaged or even exploded due to excessive pressure.
[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
