Description

Technical Field

[0001] The present 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 announcement number CN209981414U, it includes a top layer, a bottom layer, an IC chip, and a fixing layer. The top layer and the bottom layer are stacked in sequence, and the top layer is provided with multiple inclined through-holes. The IC chip sidewall is provided with multiple pins, and the pins extend along the inclined through-holes to the bottom layer. The fixing layer is provided at the point where the pins contact 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 multiple inclined through-holes. The multiple pins on the side wall of the IC chip extend along the inclined through-holes to the bottom layer. The fixing layer is provided at the point where the pins contact the through-holes of the top layer, fixing the pins to the top layer. The pins inserted into the inclined through-holes increase the contact area between the two, and after being fixed by the fixing layer, greater friction is generated to resist the external force caused 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 changing 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, and then cause 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. Summary of the Invention

[0004] The problem to be solved by the present invention is that the lithium battery protection plate will form a depression when subjected to impact force from the front. The depression squeezes the lithium battery and increases the probability of lithium battery self-ignition and explosion, making it inconvenient to provide driving safety.

[0012] Preferably, a connecting plate is rotatably provided on the outer side of the slider, and the connecting plate is used to connect the sliders so that multiple sliders can be linked and connected through the connecting plate. The slider is provided with a second roller on the side away from the connecting plate.

[0013] Preferably, a slide groove is provided at the lower end of the front side of the shell, and the slide groove is located above the mounting seat 2, and a mounting plate 2 is fixedly provided above the mounting seat 2 on the side away from the mounting plate 1, and the mounting plate 2 is arranged in an L-shape, and the mounting plate 2 is slidably connected to the shell, and a card slot is provided at the end of the mounting plate 2 away from the anti-collision component 1, and a sink groove is provided on one side of the card slot located in the middle of the shell, and a mounting column 2 is fixedly provided inside the sink groove, and the mounting columns 2 are grouped into two, and a total of eight groups are provided, and a stop block is slidably provided on the outer surface of each group of the mounting columns 2, and a spring 5 is provided around the mounting column 2 below the stop block.

[0014] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0015] 1. The anti-collision component 1 can force the obstacle to move to the side when encountering a high obstacle, preventing direct collision and removing the obstacle, ensuring the vehicle's smooth driving. It's worth mentioning that if the obstacle is heavy or the vehicle is traveling too fast, preventing timely removal, the pneumatic rod will collapse backward while offsetting the impact. This can then work in conjunction with the connecting component to force the battery pack to move backward, avoiding damage to the battery pack caused by deformation of the housing. Furthermore, while the vehicle is driving, the air guide duct and its associated components can be used to blow away softer, thinner obstacles (including but not limited to plastic bags, ropes, and snakeskin bags) hanging from the outside of the mounting plate 1, preventing them from affecting the normal operation of the anti-collision component 1.

[0016] 2. The second anti-collision component prevents obstacles from scratching the housing. Specifically, when an obstacle is located at the bottom of the housing, the second roller can roll along the surface of the obstacle and change its position upward. This can not only avoid the generation of large external forces when encountering an obstacle, but also prevent the obstacle from directly hitting the bottom of the housing during rolling, thereby preventing the bottom of the housing from being scratched by the obstacle, thereby improving the shockproof effect of the device and giving the device a certain degree of impact resistance.

[0017] 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. When starting or stopping or being hit by external forces, the battery pack can be prevented from directly hitting the inner wall of the shell. This can reduce the impact of vibration or inertia on the battery pack, so that the battery pack can work normally and reduce the chance of damage to the battery pack or disconnection of the line. 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.

[0041] 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 mounting seat 2 508. A mounting plate 2 705 is fixedly provided above the mounting seat 2 508 on the side away from the mounting plate 1 501. The mounting plate 2 705 is arranged in an L shape, and the mounting plate 2 705 is slidably connected to the shell 1. A card slot 706 is provided at the end of the mounting plate 2 705 away from the anti-collision component 1 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 mounting column 2 702 is fixedly provided inside the sink groove 701. The mounting columns 2 702 are grouped into two, and a total of eight groups are provided. A stop block 703 is slidably provided on the outer surface of each group of mounting columns 2 702, and a spring 5 704 is provided around the mounting column 2 702 below the stop block 703.

[0042] The working principle and use process of the present invention are as follows: when the car is moving in daily motion and vertical bumps are generated, the mounting seat 1 203 can slide up and down, and the dampers 1 204 and the springs at the upper and lower ends cooperate with each other to reduce the vibration during bumps. When encountering horizontal bumps or inertia generated during start-stop, the limit column 202 on the rotating base 201 and the mounting seat 1 203 will rotate in the direction of the force. At this time, the dampers 206 and the 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 base 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, it can cope with forces from any direction and enhance the anti-vibration effect on the battery pack 4.

[0043] 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 it, so that it can pass through the obstacle more smoothly; 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, so as to avoid the protrusions on the surface of the obstacle being stuck in the gaps 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, avoiding the obstacle directly hitting the anti-collision component 2 6, thereby avoiding generating additional impact force while ensuring the anti-scratch effect;

[0044] When the car is driving, if the obstacle encountered is too high, it will directly contact the roller 1 502 inside the mounting plate 1 501. The pressure rod 507 can offset the impact force and move the obstacle to the sides under the action of the roller 1 502 and the mounting plate 1 501, so that it can be discharged from the rear of the car to prevent it from 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 pressure of the impeller 506, it is transported to the air hole 503 through the air guide tube 504. In this way, light and soft obstacles such as plastic bags and paper towels hanging outside the device can be removed by air to prevent them from affecting the normal operation of the device.

[0045] In addition, when the mounting plate 1 501 is hit hard, the pneumatic rod 507 can slide out from the mounting seat 2 508 at the front and force the mounting seat 2 508 at the rear to move backward. At this time, the mounting plate 2 705 above it can be driven to move backward. 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. At this time, the mounting plate 2 705 cannot rebound. 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, avoiding the deformed shell 1 from causing pressure on the battery pack 4, thereby further improving the anti-collision performance of the device.
