Description

Technical Field

[0001] The invention relates to the technical field of lithium battery protection plates, in particular to an impact-resistant high-strength lithium battery protection plate. Background Art

[0002] A lithium battery protection board is a circuit board that is usually used in lithium battery packs to protect lithium batteries from damage such as overcharging, over-discharging, and short circuits, thereby extending the life of the lithium battery and ensuring the safety performance of the lithium battery pack.

[0003] The current lithium battery protection board is directly installed on the top of the lithium battery when in use, and is connected to the lithium battery through a connecting cable. However, when the above-mentioned lithium battery protection board is installed in the use position, when the use position vibrates or is subjected to external impact, the lithium battery protection board is directly impacted and easily damaged. At the same time, the vibration generated by the protection board will act on the cable connected to the lithium battery, making the cable connection easy to become unsoldered under the action of vibration, thereby affecting the basic use effect of the lithium battery protection board and the stable use of the lithium battery.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Please refer to Figure 1-2, the impact-resistant high-strength lithium battery protection plate includes a plate cover 1, mounting plates 2 are fixed at both ends of the inner wall of the plate cover 1, a protection plate 3 is placed on the mounting plate 2, connecting plates 14 are fixed at the lower ends of both sides of the protection plate 3, the connecting plate 14 is in contact with the top of the mounting plate 2, a positioning bolt 15 is threadedly penetrated between the connecting plate 14 and the mounting plate 2, a plurality of cables 4 are connected to the bottom of the protection plate 3, screw rods 5 are threadedly penetrated at the lower ends of both sides of the plate cover 1, a rotating block 16 for driving the screw rods 5 to rotate is fixed at one end away from each other, a clamping plate 6 is sleeved at the end of the screw rod 5 through a rotating component, a buffer protection component is provided between the inner wall of the clamping plate 6 and the rod wall of the screw rod 5 on both sides, and the buffer protection component includes two symmetrically arranged rubber pads 7, placement grooves are opened on both sides of the inner wall of the clamping plate 6, one end of the rubber pad 7 is slidably embedded in the inside of the placement groove, and the other end of the rubber pad 7 is in contact with the rod wall of the screw rod 5.

[0025] Before the lithium battery protection board performs protection work, the cable 4 is connected to the lithium battery, and the board cover 1 is put on the outside of the lithium battery, and then the rotating block 16 is rotated so that the rotating block 16 can drive the screw 5 to rotate. Driven by the screw 5, the two clamping plates 6 can approach and contact the lithium battery, so that the board cover 1 can be stably fixed on the upper end of the outer side of the lithium battery. After the position of the board cover 1 is determined, the lithium battery protection board can be impact-resistant through the setting of the board cover 1. Even when the board cover 1 and the protection board 3 are impacted, the impact can be effectively buffered through the setting of multiple rubber pads 7, and the impact on the lithium battery can be avoided as much as possible, so as to effectively protect the lithium battery.

[0026] Please refer to Figures 3-4. Multiple splints 6 are all U-shaped. The rotating assembly includes a connecting block 9, which is rotatably connected to the end of the screw rod 5. A through hole is opened inside the splint 6. The connecting block 9 is cylindrical and is arranged in the through hole. A disassembly and assembly mechanism for disassembling the splint 6 is provided between the outer side of the connecting block 9 and the inner wall of the through hole. The disassembly and assembly mechanism includes two symmetrically arranged plug blocks 10. Slots are opened on both sides of the inner wall of the through hole. Moving grooves are opened on both sides of the outer surface of the connecting block 9. Springs 11 are fixedly provided on the side of the inner walls of the two moving grooves that are close to each other. The plug block 10 and the spring 11 are fixedly connected and arranged in the moving groove. One end of the plug block 10 away from the spring 11 is inserted into the slot. Both ends of the side of the connecting block 9 away from the screw rod 5 are provided with strip holes. The strip hole is connected to the moving groove. A sliding rod 12 is slidably penetrated in the strip hole. One end of the sliding rod 12 is fixedly connected to the plug block 10, and the other end passes through the strip hole and extends to the outside.

[0027] Due to the rotational connection between the connecting block 9 and the screw rod 5, when the clamping plate 6 contacts the lithium battery, the screw rod 5 can rotate and push the clamping plate 6 to squeeze the lithium battery to complete the position determination of the plate cover 1. After the rubber pad 7 has been used for a long time inside the clamping plate 6, after the plate cover 1 is removed from the lithium battery, the two slide bars 12 are pulled so that the slide bars 12 drive the plug block 10 to be pulled out of the slot. At this time, the connecting block 9 can be separated from the clamping plate 6, and the rubber pad 7 inside the clamping plate 6 can be taken out and replaced to ensure that the rubber pad 7 can always have a good buffer protection effect.

[0028] Please refer to Figure 1. The internal thread of the protection plate 3 is penetrated by a plurality of positioning rods 8. The upper end of the positioning rod 8 is provided with a thread. The upper end of the positioning rod 8 is matched with the thread of the plate cover 1. A clamping positioning mechanism is provided between the positioning rod 8 and the cable 4. The clamping positioning mechanism includes a pull ring 13. The lower end of the positioning rod 8 is provided with a threading hole. The cable 4 passes through the threading hole and extends to the outside. The bottom of the protection plate 3 is provided with a plurality of pressing grooves. The pressing grooves are matched with the cable 4 and the positioning rod 8. The pull ring 13 is rotatably sleeved on the internal upper end of the positioning rod 8. The internal upper end of the positioning rod 8 is provided with a rotating hole that cooperates with the rotation of the pull ring 13. Before the cable 4 is connected, the cable 4 is passed through the threading hole of the positioning rod 8 to connect with the lithium battery, and then the pull ring 13 is rotated to rotate and move the positioning rod 8 upward. With the cooperation of the pressing groove, the positioning rod 8 cooperates with the threading hole to squeeze one end of the cable 4 into the pressing groove, and fixes one end of the cable 4, so that when the plate cover 1 and the protective plate 3 are impacted and vibrated, the cable 4 cannot be desoldered and separated from the protective plate 1, so that the protective plate 3 can stably protect the lithium battery in time.
