[0002] During the production and processing of the battery module, the purpose of applying glue to the side panel and fixing it on the side of the battery module and curing the glue is to enhance the connection strength and sealing between the side panel and the battery module, ensure the structural stability of the battery module and prevent interference from external factors. Prevent the side panel from loosening, deformation or damage caused by external factors. At the same time, the curing treatment can ensure that the glue reaches the best performance and effect at a certain temperature and time.

[0003] In the prior art, the side panels need to be coated with glue and fixed on the sides of the battery module, and then transported to a heating oven for glue curing at a certain temperature and time. Due to thermal expansion of the glue during the heating and curing process, gaps appear between the side panels and the sides of the battery module, and they cannot fit completely, which reduces the connection strength and sealing between the side panels and the battery module, causing the battery module to become loose, damaged, and leak.

DETAILED DESCRIPTION

[0017] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. Before describing in detail the technical solutions of each embodiment of the present invention, the nouns and terms involved are explained. In this specification, components with the same name or the same number represent similar or identical structures and are only for illustrative purposes.

[0018] like Figure 1As shown, a battery module side plate pressure maintaining device includes a main frame 10 placed on the top of a battery module with parallel side plates on both sides. The battery module can be square, polygonal or flat. The polygon is selected so that the two side walls are parallel and symmetrical. The battery module is preferably square. It also includes fixed clamps 103, which are located at both ends of the main frame 10, and at least one fixed clamp 103 slides relative to the main frame 10, and the plane of the fixed clamp 103 faces the side plate of the battery module; and an adjusting member 20, which is installed at one end of the main frame 10 and can drive the fixed clamp 103 sliding relative to the main frame 10 to move in the vertical direction of the battery module side plate, wherein the two ends of the main frame 10 are symmetrically arranged about the middle part thereof, and the two fixed clamps 103 are arranged at the two ends of the main frame 10, and one or two fixed clamps 103 can slide relative to the main frame 10. When only one of the fixing clamps 103 can slide relative to the main frame 10, the adjusting member 20 drives the fixing clamp 103 to move toward the side plate of the battery module until the other side of the battery module rests on the fixing clamp 103 installed on the main frame 10, that is, the side plate is pressed against the battery module through the fixing clamp 103; when both fixing clamps 103 can slide relative to the main frame 10, the number of adjusting members 20 is equal to the slidable fixing clamp 103, and the adjusting members 20 on both sides drive the corresponding fixing clamps 103 to move toward the side plate of the battery module, so that the side plate is pressed against the battery module. After the battery module and the side plate are pressed, a certain holding force is given to the side plate, so that the battery module on the tray and the pressure-maintaining device enter the heating drying room together, and the battery module glue is heated and cured to avoid the problem of incomplete fitting between the side plate and the battery module.

[0019] like Figure 1-Figure 3 As shown, the adjustment member 20 includes a fixing rod 205 installed on the fixing clamp 103 and a pair of angle steels 201 fixedly installed at one end of the main frame 10, a second angle piece 210 is rotatably installed between the two angle steels 201, and the fixing rod 205 is rotatably connected to the end away from the fixing clamp 103 with a first angle piece 209 that rotates relative to the second angle piece 210, wherein the rotation of the second angle piece 210 can drive the first angle piece 209 to rotate, and the rotation of the first angle piece 209 drives the fixing rod 205 to move outward, and the fixing rod 205 on one side drives the two fixing clamps 103 to move relatively away from each other, so that after the battery module and the side panel are bonded in the heating oven, the fixing clamp 103 loosens the battery module and the side panel for subsequent removal.

[0020] An adjusting support rod 202 is rotatably connected between a pair of angle steels 201, and the back-and-forth rotation of the adjusting support rod 202 can drive the extension and contraction of the fixing rod 205, wherein a first positioning axis 206, a second positioning axis 207 and a third positioning axis 208 distributed in a triangle are fixedly installed between the two angle steels 201, one end of the second angle piece 210 is rotatably connected to the angle steel 201 through the second positioning axis 207, the first positioning axis 206 is installed at the other end of the second angle piece 210, and is plugged into a pair of first angle pieces 209 ends and rotatably connected to the first angle piece 209, and the adjusting support rod 202 includes a first positioning axis 208 rotatably connected to the third positioning axis 208. The shift block 2022, a handle 2021 fixedly installed at one end of the shift block 2022 and a waist-shaped hole 2023 opened at the other end of the shift block 2022, the waist-shaped hole 2023 is sleeved on the outside of the first positioning shaft 206, the shift block 2022 is located between a pair of first angle pieces 209, and the fixed rod 205 can be driven to retract back and forth through the shift block 2022 by toggling the handle 2021 back and forth. It also has a self-locking function. The above-mentioned device is an elbow clamp assembly, which is a prior art, thereby driving the fixed clamp plate 103 to be pressed toward the side plate of the battery module to prevent the glue from expanding due to heat in the heating oven, resulting in a gap between the side plate and the battery module.

[0021] like Figure 2 and Figure 3 As shown, an adjusting cap 204 is provided on the fixing rod 205, and the end of the adjusting cap 204 away from the fixing rod 205 is threadedly connected to the connecting rod 203, and the connecting rod 203 and the first angle piece 209 are rotatably connected at one end facing each other, wherein the distance between the fixing rod 205 and the connecting rod 203 can be adjusted by twisting the adjusting cap 204, thereby adjusting the distance between the two fixing clamps 103, so as to clamp the side panels of different battery modules.

[0022] In addition to the above-mentioned method, the adjusting member 20 can also be pushed by a screw, that is, the screw is threadedly connected to the side of the main frame 10, one end of the screw is rotatably connected to the fixed clamp 103, and a handle can be installed on the other end of the screw. The fixed clamp 103 is driven to move back and forth relative to the battery module by rotating the handle, and the side panel can also be pressed on the side of the battery module to facilitate heating and drying.

[0023] like Figure 1As shown, the main frame 10 includes at least two main frames 101 arranged equidistantly, and a reinforcing plate 106 is installed between several main frames 101. The number of main frames 101 is preferably two. If two main frames 101 are used, the adjusting member 20 is located on the side of the two main frames 101 facing away from each other. If the number of main frames 101 is large, the adjusting member 20 is located on the side of the two main frames 101 facing away from each other at the end. The main frame 101 is preferably n-shaped, and the middle part of the main frame 101 is placed on the top of the battery module. The middle part of the main frame 101 is installed with an insulating pad 102 separated from the top of the battery module. The insulating pad 102 is used to separate the main frame 101 from the battery module to avoid short circuit.

[0024] like Figure 1 As shown, a guide shaft 107 slidably connected to a reinforcing plate 106 is fixedly installed on one side of a fixed splint 103 that slides relative to the main frame 10, wherein a hole is opened on the reinforcing plate 106, in which a guide bearing is installed, and the guide shaft 107 slides back and forth between the guide bearing and the reinforcing plate 106, thereby improving the stability of the back and forth movement of the fixed splint 103.

[0025] The fixing plates 103 are each installed with a backing plate 104 on the side facing each other. The backing plate 104 presses the side plate against the side wall of the battery module to prevent hard contact between the fixing plates 103 and the battery module to avoid excessive support force and damage to the battery module.

[0026] The above-described embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
