Description

Technical Field

[0001] The utility model relates to the technical field of battery module fastening, in particular to a battery module transverse fastening mechanism with strong compatibility. Background Art

[0002] During the processing of the battery module, in order to ensure the stability of its position, a tightening mechanism is usually required to limit its lateral position. The battery module is usually placed at one end fixed by the tightening mechanism, and then the tightening of the battery module is achieved by moving one set of clamping components. For example, a square battery module tightening device with publication number CN219959281U arranges the square batteries in order on the support rail at the bottom of the carrier, tightens the square battery module laterally, starts the linear cylinder to drive the longitudinal tightening plate to move, and tightens the square battery module longitudinally. When the tightening pressure reaches the preset value of the pressure sensor, the servo motor stops and the lateral tightening ends. After bundling the square battery module, the longitudinal and transverse tightening structures are loosened, the square battery module is taken out, and the next process is entered. The utility model simplifies the structure and shortens the tightening and loosening process. However, the square battery module tightening device still has the following disadvantages during actual use:

[0003] Although the above-mentioned clamping device realizes the limitation of the battery module, the same clamping mechanism cannot be applied to the limitation of the battery module with a planar structure or a curved structure, and has limitations in use. Moreover, when the battery module is processed after being limited, instability is prone to occur, resulting in displacement of the processing position. In view of the above problems, it is urgently necessary to carry out innovative design based on the original clamping mechanism. Utility Model Content

[0004] The purpose of the utility model is to provide a battery module lateral tightening mechanism with strong compatibility, so as to solve the problem that the same tightening mechanism proposed in the above-mentioned background technology cannot be applied to the positioning of flat structure or arc structure battery modules, has limitations when used, and is prone to instability when processing the battery module after positioning, resulting in processing position deviation.

[0005] To achieve the above object, the utility model provides the following technical solutions: a battery module transverse tightening mechanism with strong compatibility, provided with a base, a motor is installed on the side of the base through bolts, and the output shaft of the motor is connected to a screw rod, a movable seat is threadedly installed on the outer side of the screw rod, and the movable seat is slidably arranged above the base;

[0006] It comprises: a first clamping mechanism, which is arranged on the side of the movable seat, and the first clamping mechanism is moved close to the second clamping mechanism to tighten the battery module;

[0007] The fixing seat is fixed to an end of the base away from the motor, and a second clamping mechanism is arranged on a side surface of the fixing seat.

[0008] Preferably, the first clamping mechanism includes a first clamping plate fixed to the side of the movable seat, and an adjusting rod is passed through the inside of the movable seat and the first clamping plate, and the adjusting rod and the movable seat are slidably connected, the connecting plate can be slidably installed on the movable seat through the adjusting rod, and the connecting plate and the first clamping plate can be locked by rotating the adjusting rod.

When the connecting plate is installed, it is convenient for the first clamping plate to clamp the battery module with a planar structure, and after the connecting plate is removed, it is convenient for the first clamping plate to clamp the battery module with an arc structure.

[0010] Preferably, the side of the connecting plate close to the first clamping plate is a curved structure, and the other side of the connecting plate is flush with the surface of the first clamping plate, and the connecting plate and the fixing groove match each other. At the same time, the fixing groove is opened on the side of the first clamping plate away from the movable seat. After installation, the connecting plate can be flush with the first clamping plate, and after disassembly, the surface of the first clamping plate is in a concave state.

[0011] Preferably, the second clamping mechanism includes a movable rod penetrating the side of the fixing seat, and the fixing seat is hollow, and the movable rod and the fixing seat are slidably connected, and when the second clamping plate is pushed, the movable rod and the fixing plate can be driven to slide on the fixing seat.

[0012] Preferably, a spring is wound around the outer side of the movable rod to reset it, and a fixed plate is fixed to one end of the movable rod, and the fixed plate and the inner wall of the fixed seat slide in close contact, and after the fixed plate moves, negative pressure is generated between it and the fixed seat, and the negative pressure gas can be transmitted to the second splint through the gas pipe.

[0013] Preferably, the top of the fixing seat is connected to the second clamping plate through an air pipe, and the second clamping plate is hollow inside, and the second clamping plate is fixed to the other end of the movable rod, and fixing holes are evenly reserved on the side of the second clamping plate away from the fixing seat. After the battery module is clamped, the gas between the fixing hole and the battery module can be sucked out to achieve negative pressure limiting of the battery module.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the battery module transverse tightening mechanism with strong compatibility can be adjusted according to the shape of the battery module, thereby meeting the position limitation of the battery module with a planar structure or a curved structure, and after the battery module is limited, the stability can be further improved by negative pressure adsorption for subsequent processing. The specific contents are as follows:

[0015] 1. When the side of the battery module is a planar structure, the connecting plate can be slidably installed in the movable seat through the adjusting rod, and then the connecting plate is kept stable and the adjusting rod is rotated to make the connection between the connecting plate and the movable seat stable through the threaded connection, so that the surface of the first clamping plate is a planar structure;

[0016] Furthermore, when the side of the battery module is a curved structure, the adjusting rod can be rotated to drive the connecting plate to separate from the fixing groove. After the connecting plate is removed, the surface of the first clamping plate is in a concave state, thereby tightening the battery module with the curved structure.

[0017] 2. When the second clamping plate is pushed, it drives the movable rod and the fixed plate to move in the fixed seat, so that negative pressure is generated between the fixed plate and the fixed seat, which can draw the gas between the fixing hole and the battery module into the second clamping plate, and then transmit it to the fixed seat through the gas pipe. In this way, after clamping the battery module, the clamping stability can be improved by negative pressure adsorption. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0027] Embodiment 1: In order to solve the problems existing in the prior art, this embodiment adopts the following technical scheme: a transverse clamping mechanism for a battery module with strong compatibility is provided, which is provided with a base 1, and a motor 2 is installed on the side of the base 1 by bolts, and the output shaft of the motor 2 is connected to a screw rod 3, and a movable seat 4 is installed on the outer thread of the screw rod 3, and the movable seat 4 is slidably arranged above the base 1; it includes: a first clamping mechanism, which is arranged on the side of the movable seat 4, and the first clamping mechanism realizes the clamping of the battery module by moving toward the second clamping mechanism; a fixed seat 9, which is fixed to the end of the base 1 away from the motor 2, and a second clamping mechanism is arranged on the side of the fixed seat 9.

[0028] The existing tightening mechanism is not suitable for the positioning of flat or curved battery modules and has limitations when used, such as Figure 1-Figure 4 As shown, the first clamping mechanism includes a first clamping plate 5 fixed to the side of the movable seat 4, and the movable seat 4 and the first clamping plate 5 are penetrated by an adjusting rod 6, and the adjusting rod 6 and the movable seat 4 are slidably connected; a connecting plate 7 is provided at the end of the adjusting rod 6, and the adjusting rod 6 and the connecting plate 7 are rotatably connected, and the adjusting rod 6 and the first clamping plate 5 are threadedly connected; the side of the connecting plate 7 close to the first clamping plate 5 is an arc surface structure, and the other side of the connecting plate 7 is flush with the surface of the first clamping plate 5, and the connecting plate 7 and the fixing groove 8 are consistent with each other, and the fixing groove 8 is opened on the side of the first clamping plate 5 away from the movable seat 4; firstly, the battery module to be tightened is placed on the end of the base 1 close to the fixing seat 9, and then the first clamping plate is adjusted according to the shape of the side of the battery module 5 is adjusted. When the side of the battery module is a flat structure, the connecting plate 7 can be slidably installed in the movable seat 4 through the adjusting rod 6, and then the stability of the connecting plate 7 is maintained and the adjusting rod 6 is rotated. The connection between the connecting plate 7 and the movable seat 4 is stable through the threaded connection, so that the surface of the first clamping plate 5 is a flat structure. When the side of the battery module is a curved structure, the adjusting rod 6 can be rotated to drive the connecting plate 7 to separate from the fixing groove 8. After the connecting plate 7 is removed, the surface of the first clamping plate 5 is in a concave state, so that the battery module with the curved structure is tightened. Then the motor 2 drives the screw rod 3 to rotate, and through the threaded transmission between the screw rod 3 and the movable seat 4, the movable seat 4 and the first clamping plate 5 are driven to move horizontally toward the fixed seat 9 to clamp the battery.

[0029] Embodiment 2: When the existing tightening mechanism is used to process the battery module after limiting the position, it is easy to become unstable, resulting in the deviation of the processing position. Therefore, this embodiment adopts the following technical solutions, such as Figure 1-Figure 5 - Figure 6As shown, the second clamping mechanism includes a movable rod 10 that passes through the side of the fixed seat 9, and the fixed seat 9 is hollow, and the movable rod 10 and the fixed seat 9 are slidably connected; a spring for returning the movable rod 10 is wound around the outside of the movable rod 10, and a fixing plate 11 is fixed to one end of the movable rod 10, and the fixing plate 11 and the inner wall of the fixed seat 9 fit and slide; the top of the fixed seat 9 is connected to the second clamping plate 13 through the air pipe 12, and the second clamping plate 13 is hollow, and the second clamping plate 13 is fixed to the other end of the movable rod 10, and the second clamping plate 13 is evenly reserved on the side away from the fixed seat 9 with fixing holes 14; when the first clamping plate 5 contacts the battery module, the battery module can be pushed to fit closely with the second clamping plate 13, and the second clamping plate 13 can be pressed against the battery module. After being pushed, the plate 13 drives the movable rod 10 to slide on the fixed seat 9, and the movable rod 10 drives the fixed plate 11 to move in the fixed seat 9, so that negative pressure is generated between the fixed plate 11 and the fixed seat 9, and the gas between the fixing hole 14 and the battery module can be drawn into the second clamping plate 13, and then transmitted to the fixed seat 9 through the air pipe 12. In this way, after the battery module is clamped, the clamping stability can be improved by negative pressure adsorption. When the processing of the battery module is completed later, the first clamping plate 5 is separated from the battery module to release the push on it, and the second clamping plate 13 can be driven to move through the resilience of the spring, and the battery module can be pushed to move, so that the negative pressure between the battery module and the second clamping plate 13 can disappear, making it convenient to take out the battery module.
