Description

Technical Field

[0001] The invention relates to the technical field of lithium battery protection plates, in particular to a shock-proof and collision-proof lithium battery protection plate. Background Art

[0002] In the patent application with application announcement number CN209981414U, it includes a top layer, a bottom layer, an IC chip and a fixed layer. The top layer and the bottom layer are stacked in sequence, and the top layer is provided with a plurality of inclined through holes; the side wall of the IC chip is provided with a plurality of pins, and the pins extend along the inclined through holes to the bottom layer; the fixed layer is provided at the contact point between the pins and the through holes of the top layer. The advantages are: the top layer and the bottom layer are stacked in sequence, and the top layer is provided with a plurality of inclined through holes; the plurality of pins on the side wall of the IC chip extend along the inclined through holes to the bottom layer; the fixed layer is provided at the contact point between the pins and the through holes of the top layer to fix the pins on the top layer. The insertion of the pins into the inclined through holes increases the contact area between the two, and then after the fixed layer is fixed, a greater friction force is generated to resist the external force generated by vibration, thereby extending the service life of the lithium battery protection board.

[0003] In the prior art including the above-mentioned patents, the lithium battery protection plates in the above-mentioned patents and prior art have relatively simple effects. When driving, obstacles may be encountered due to changeable road conditions. Once the obstacles enter the bottom of the vehicle, they may impact the lithium battery and cause damage to the lithium battery. In these unexpected situations, the impact force is mostly a frontal impact. The impact from the front will cause the outer shell of the protection plate to deform and collapse inward, eventually causing damage to the lithium battery body, thereby causing the lithium battery to spontaneously combust or explode. In summary, the above-mentioned lithium battery protection plates have relatively simple effects and cannot reduce the probability of the lithium battery body being damaged, and thus cannot provide protection for driving safety.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: 1. Through the setting of the anti-collision component 1, when encountering a higher obstacle, the obstacle can be forced to move to the sides, which can not only avoid direct collision with the obstacle, but also play the role of removing obstacles, providing a certain guarantee for the smooth driving of the car. It is worth mentioning that if the obstacle is heavy or the speed is too fast and the obstacle cannot be removed in time, the pneumatic rod will collapse backwards while offsetting the impact force. At this time, it can cooperate with the connection component to force the battery pack to move backwards and avoid the battery pack from being damaged after the shell is deformed; in addition, when the car is driving, the air guide groove and its related components can be used to blow away the softer and thinner obstacles (including but not limited to plastic bags, ropes, snakeskin bags) hanging outside the mounting plate 1 to prevent them from affecting the normal operation of the anti-collision component 1; 2. By setting the anti-collision component 2, it is possible to prevent obstacles from scratching the shell. Specifically, when the obstacle is located at the bottom of the shell, the roller 2 can roll along the surface of the obstacle and change its position upward, which can avoid generating a large external force when encountering an obstacle and prevent the obstacle from directly hitting the bottom of the shell when rolling, thereby preventing the bottom of the shell from being scratched by the obstacle, thereby improving the shockproof effect of the device and making the device have a certain impact resistance effect; 3. The setting of the shockproof component can prevent frequent vibrations from affecting the battery pack. Specifically, when the car enters a bumpy road, the battery pack can be kept relatively still with the ground, and when starting or stopping or receiving an external force impact, the battery pack can be prevented from directly hitting the inner wall of the shell, thereby reducing the impact of vibration or inertia on the battery pack, so that the battery pack can work normally and reduce the probability of damage to the body or disconnection of the line; and the shockproof component can not only solve the vertical or horizontal forces, but also when the car is on uphill or downhill or other special road conditions, with the cooperation of all components of the shockproof component, it can cope with external forces from different directions.

[0028] On the outer side of the slider 601, a connecting plate 604 is rotatably arranged. The connecting plate 604 is used to connect the slider 601 so that the slider 601 can be linked. On the side of the slider 601 away from the connecting plate 604, a roller two 605 is arranged. Between the rollers two 605, they are rotatably connected through a connecting piece 606. The connecting piece 606 can move upward so that the rollers two 605 move upward together.

[0029] A slide groove 7 is provided at the lower end of the front side of the shell 1, and the slide groove 7 is located above the second mounting seat 508. A second mounting plate 705 is fixedly arranged above the second mounting seat 508 on the side away from the first mounting plate 501. The second mounting plate 705 is arranged in an L shape, and the second mounting plate 705 is slidably connected to the shell 1. A card slot 706 is provided at the end of the second mounting plate 705 away from the anti-collision component 5. A sink groove 701 is provided on one side of the card slot 706, which is located in the middle of the shell 1. A second mounting column 702 is fixedly arranged inside the sink groove 701. The second mounting columns 702 form a group of two, and there are eight groups in total. A stopper 703 is slidably arranged on the outer surface of each group of the second mounting columns 702, and a spring 5 704 is arranged around the second mounting column 702 below the stopper 703.

[0030] The working principle and use process of the present invention are as follows: when the automobile is traveling daily and vertical bumps are generated, the mounting seat 1 203 can slide up and down, and the dampers 1 204 and springs at the upper and lower ends thereof cooperate with each other during sliding to reduce the vibration during bumps. When encountering horizontal bumps or inertia generated during start-stop, the limiting column 202 and the mounting seat 1 203 on the rotating base 201 will rotate in the direction of the force. At this time, the dampers 206 and springs 207 on both sides of the mounting seat 1 203 cooperate with each other to reduce the impact of the horizontal force on the battery pack 4. When the rotating base 201 rotates, the foot 210 can slide on the outer surface of the slide bar 209, so that the support plate 3 can change its position in accordance with the rotation of the base 201, and under the action of the spring 3 211, the position of the support plate 3 can be prevented from changing too quickly or colliding with the anti-vibration component 2. In summary, through the setting of the anti-vibration component 2, forces from any direction can be coped with, and the anti-vibration effect on the battery pack 4 can be enhanced. When the car is driving, if the obstacle is not avoided in time, the roller 2 605 can prevent the obstacle from scratching the bottom of the shell 1 and reduce the friction between the obstacle and the shell 1, so that it can pass through more smoothly when encountering the obstacle; and when the obstacle is under the roller 2 605, the connecting pieces 606 on both sides of the roller 2 605 can make each anti-collision component 2 6 move upward to avoid the protrusions on the surface of the obstacle being stuck in the gap between the anti-collision components 2 6 when encountering an irregular obstacle, thereby further enhancing the anti-scratch effect; it is worth mentioning that when encountering an obstacle, after the first anti-collision component 2 6 is displaced, the next anti-collision component 2 6 can be moved upward in advance through the connecting plates 604 on both sides thereof, so that when the obstacle encounters the second anti-collision component 2 6, it can be smoother and avoid the obstacle directly hitting the anti-collision component 2 6, thereby ensuring the anti-scratch effect while avoiding additional impact force; When the car is driving, if the obstacle encountered is too high, the obstacle will directly contact the roller 502 in the mounting plate 501. The impact force can be offset by the pressure rod 507 and the obstacle can be moved to both sides under the action of the roller 502 and the mounting plate 501, so that it can be discharged from the rear of the car to avoid damaging other components of the device. It is worth mentioning that the air guide groove 505 can guide the oncoming wind to the impeller 506, and under the pressurized action of the impeller 506, it is transported to the air hole 503 through the air guide pipe 504, so that the plastic bags, paper towels and other light and soft foreign objects hanging outside the device can be removed by air to avoid affecting the normal operation of the device. In addition, when the mounting plate 1 501 is hit hard, the pneumatic rod 507 can slide out from the mounting seat 2 508 located in the front and force the mounting seat 2 508 located in the rear to move backward, and at this time, the mounting plate 2 705 above it can be driven to move backward, and the upper support plate 3 and the battery pack 4 can be forced to move backward together through the pull rope 707, and when the slot 706 moves to the top of the corresponding stop block 703, the stop block 703 can be bounced up by the spring 5 704, and the mounting plate 2 705 cannot rebound at this time. In this way, when the shell 1 receives a huge impact, the battery pack 4 can be kept away from the front end of the shell 1 to avoid the deformation of the shell 1 from causing pressure on the battery pack 4, thereby further improving the anti-collision performance of the device.
