DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figures 1 - 5 , the present utility model provides two technical solutions:

[0026] The first embodiment: A four - corner positioning frame device for a lithium - battery PACK combination, including a rear plate 1. A fixing component 2 is arranged on the front side of the rear plate 1 to fix the position of the lithium battery. The fixing component 2 includes:

[0027] The positioning component 21 is arranged on the front side of the rear plate 1 for positioning the lithium battery. The positioning component 21 includes slots 213 fixedly installed at the left and right ends of the front side of the rear plate 1. A connecting frame 214 is movably installed on the front side of the slot 213, and a fixing plate 215 is fixedly installed on the front side of the connecting frame 214.

[0028] The disassembly component 22 is arranged on the rear side of the clamping plate 225 for facilitating the disassembly and replacement of a single lithium battery. The disassembly component 22 includes a movable slot 221 opened inside the fixing plate 215. Two limiting plates 223 are opened on the front side of the fixing plate 215. Movable plates 222 are movably installed at both the left and right ends inside the movable slot 221. Two second connecting plates 229 are movably hinged to the rear sides of the movable plates 222, and the two second connecting plates 229 are obliquely installed. One ends of the two second connecting plates 229 are movably hinged to a clamping plate 225. A driving component is arranged inside the movable slot 221 for driving the clamping plate 225 to move back and forth. The driving component includes a positive and reverse screw rod 224 movably installed inside the movable slot 221. Movable cylinders 227 are threadedly installed at both the top and bottom of the outer side of the positive and reverse screw rod 224. First connecting plates 226 are movably hinged to both the left and right sides of the movable cylinder 227, and the first connecting plates 226 are obliquely installed. First insulating films 228 are fixedly installed at both the left and right ends of the front side of the rear plate 1. A second insulating film 2210 is fixedly installed on the rear side of the clamping plate 225, and the insulating performance of the device can be improved through the first insulating film 228 and the second insulating film 2210. One ends of the two second connecting plates 229 movably penetrate through the inside of the two limiting plates 223 and are movably hinged to the front side of the clamping plate 225, and the two second connecting plates 229 can limit the movement track of the movable plate 222 through the two limiting plates 223. The bottom end of the positive and reverse screw rod 224 is movably installed on the bottom surface of the movable slot 221. The top end of the positive and reverse screw rod 224 movably penetrates through the inside of the movable slot 221 and extends to the top surface of the fixing plate 215. One end of the first connecting plate 226 is movably hinged to the opposite side of the movable plate 222, and rotating the positive and reverse screw rod 224 can drive the movable cylinder 227 to move towards the opposite side. Then the movable cylinder 227 will drive the first connecting plate 226 to move the movable plate 222.

[0029] By setting the positive and reverse screw rod 224 and the second insulating film 2210, it is convenient to disassemble and repair a single lithium battery. When it is necessary to disassemble the lithium battery, rotate the positive and reverse screw rod 224 to drive the movable cylinder 227 to move towards the opposite side. Then the movable cylinder 227 will drive the first connecting plate 226 to push the movable plate 222 to move horizontally. At this time, the movable plate 222 will make the clamping plate 225 move forward away from the outside of the lithium battery through the second connecting plate 229. Then the lithium battery can be disassembled, which is convenient for disassembling a single lithium battery and avoids causing unnecessary damage to other battery components, and has good practicability.

[0030] The second implementation mode, the main difference from the first implementation mode is that: the positioning component 21 further includes first positioning blocks 211 fixedly installed at the left and right ends of the top and bottom surfaces of the rear plate 1. A positioning frame 212 is provided on the front side of the slot 213. A front plate 216 is fixedly installed on the front side of the fixing plate 215. Second positioning blocks 217 are fixedly installed at the left and right ends of the top and bottom surfaces of the front plate 216, and the second positioning blocks 217 and the first positioning blocks 211 are of matching size specifications. The rear side of the connecting frame 214 is closely attached to the inner side of the positioning frame 212, and the connecting frame 214 can fix the lithium battery through the positioning frame 212 and the slot 213.

[0031] The lithium battery can be fixed by the provided slot 213 and the connecting frame 214. During use, place the lithium battery inside the slot 213. Then pick up the front plate 216 and insert the connecting frame 214 into the positioning frame 212. At this time, the disassembly component 22 is attached to the front side of the lithium battery. Then pass the bolt through the first positioning block 211 and the second positioning block 217 to connect the front plate 216 and the rear plate 1 together to fix the lithium battery, which is convenient for assembly.

[0032] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0033] During use, the user places the lithium battery inside the slot 213. Then pick up the front plate 216 and insert the connecting frame 214 into the positioning frame 212. At this time, the clamping plate 225 will be attached to the front side of the lithium battery. Then pass the bolt through the first positioning block 211 and the second positioning block 217 to thread the front plate 216 and the rear plate 1 together. Multiple rear plates 1 and front plates 216 can be threaded outside the bolt for connection to form a battery pack as needed. Then rotate the nut to make multiple front plates 216 and rear plates 1 closely fit together to fix the lithium battery. When it is necessary to disassemble one group of lithium batteries, when it is necessary to disassemble the lithium battery, rotate the left-right threaded screw 224 to drive the movable cylinder 227 to move towards the opposite side. Then the movable cylinder 227 will drive the first connecting plate 226 to make the push movable plate 222 move horizontally. At this time, the movable plate 222 will make the clamping plate 225 move forward away from the outside of the lithium battery through the second connecting plate 229. Then the lithium battery can be disassembled and replaced.
