[0033] See also Figure 4 The upper ends of the bottom plate 1 401 and the bottom plate 2 402 are fixedly connected with the top plate 405, the two sides of the bottom plate 1 401 are fixedly embedded with sealing strips 1 406, and the side of the bottom plate 2 402 close to the bottom plate 1 401 is fixedly embedded with sealing strips 2 407, the sealing strips 1 406 and the sealing strips 2 407 are both made of silicone material, and the sealing strips 1 406 and the sealing strips 1 406 and the sealing strips 1 406 and the sealing strips 2 407 are movably abutted against each other, and the sealing strips 1 406 and the sealing strips 2 407 can prevent dust or moisture from entering the bottom of the power battery.

[0035] See also Figure 8 The detection structure 7 includes a laser emitter 701 and a laser receiver 702. The connection between the laser emitter 701 and the laser receiver 702 is an electrical connection. The laser receiver 702 can receive the laser emitted by the laser emitter 701. A straight screw 703 is fixedly installed at the center of the lower end of the laser emitter 701, and the straight screw 703 passes through the fixed rod 607. The laser receiver 702 is electrically connected to the central control of the car.

[0036] See also Figure 8 A threaded seat 704 is fixedly installed at the center of the upper end of the laser receiver 702, a nut 705 is threadedly sleeved on the lower end of the straight screw 703, a bent screw 706 is installed on the internal thread of the threaded seat 704, and the connection between the bent screw 706 and the protective frame 2 is a fixed connection. The laser transmitter 701 and the laser receiver 702 are located on the same horizontal line.

[0037] Working principle of preventing the bottom plate from squeezing the power battery pack: When the bottom plate structure 4 on the lower side of the power battery pack of the new energy vehicle is hit, the bottom plate 1 401 or the bottom plate 2 402 will move upward under the drive of the obstacle, so that the multiple bottom plates 1 401 and the two bottom plates 2 402 can avoid the obstacle, and because the bottom cross-section of the bottom plate 1 401 and the bottom plate 2 402 is conical, the bottom plate 1 401 and the bottom plate 2 402 are not easily deformed when hit; when the car is running normally, the multiple bottom plates 1 401 and the two bottom plates 2 402 are distributed in a straight line, and at this time the laser receiver 70 2 can receive the laser emitted by the laser emitter 701, and when the bottom plate 1 401 or the bottom plate 2 402 is collided and the height changes, the bottom plate 1 401 or the bottom plate 2 402 will block the laser emitted by the laser emitter 701, and the laser receiver 702 cannot receive the laser emitted by the laser emitter 701. At this time, the laser receiver 702 will send a warning to the central control of the car to remind the driver that the bottom plate structure 4 on the lower side of the power battery pack is collided, so as to avoid deepening the collision degree of the bottom plate structure 4, and can effectively prevent the bottom plate 1 401 and the bottom plate 2 402 from deforming and squeezing the power battery pack;

[0038] When the laser transmitter 701 or the laser receiver 702 is damaged, the personnel can unscrew the nut 705 from the straight screw 703, and the straight screw 703 can be pulled out from the fixed rod 607, so that the laser transmitter 701 can be easily replaced. The personnel can rotate the laser receiver 702 to disengage the threaded seat 704 from the bent screw 706, so that the laser receiver 702 can be easily replaced.

[0039] Embodiment 2

[0040] See also Figure 7 This embodiment further explains Example 1. The deceleration assembly 5 includes a cam 501 movably embedded in the bracket 1. The outer side of the cam 501 is fixedly sleeved with an anti-slip pad 502. A limited rotation groove 503 is provided inside the bracket 1 at a position corresponding to the cam 501. The limited rotation groove 503 can limit the rotation angle of the cam 501. A positioning shaft 504 is fixedly installed on the outer side of the cam 501.

[0041] See also Figure 7 The cam 501 is rotatably connected to the bracket 1 through a limit groove 503 and a positioning shaft 504. Two symmetrically distributed coil springs 505 are fixedly sleeved on the outer side of the positioning shaft 504, and the outer ends of the coil springs 505 are fixedly connected to the bracket 1. The coil springs 505 can drive the cam 501 to rotate. The cam 501 is in active contact with the tooth plate 9 through the anti-skid pad 502, and the anti-skid pad 502 can increase the friction between the cam 501 and the tooth plate 9.

[0042] When the tooth plate 9 is moved upward by the obstacle, the tooth plate 9 will move upward accordingly. During the upward movement, the tooth plate 9 drives the cam 501 to rotate in the limit groove 503 through the anti-skid pad 502. At this time, the cam 501 will not affect the upward movement speed of the tooth plate 9. When the bottom plate 401 or the bottom plate 402 is free from the obstacle, the bottom plate 401 or the bottom plate 402 will be reset under the drive of multiple springs 403. During the process of the tooth plate 9 moving down and restoring with the bottom plate 1 401 or the bottom plate 2 402, the cam 501 cannot rotate under the obstruction of the limit groove 503, so the tooth plate 9 and the anti-skid pad 502 of the cam 501 are in contact and friction, which can effectively reduce the downward movement speed of the bottom plate 1 401 or the bottom plate 2 402, and avoid the spring 403 driving the bottom plate 1 401 or the bottom plate 2 402 to move down and reset too fast to produce secondary impact vibration.

[0043] Embodiment 3

[0044] See also Figure 2 and Figure 6This embodiment further explains the second embodiment. The reset mechanism 6 includes a dual-axis motor 601 installed inside the new energy vehicle. A rotating shaft 602 is fixedly installed at both ends of the dual-axis motor 601. A roller 603 is fixedly sleeved on one end of the rotating shaft 602 away from the dual-axis motor 601. The roller 603 can reel in a steel cable 604. The steel cable 604 is wound around the outer side of the roller 603. A plurality of connecting seats 605 are movably sleeved on the outer side of the steel cable 604. When the roller 603 is in a tightened state with respect to the steel cable 604, the steel cables 604 on the outer sides of the bottom plate 1 401 and the bottom plate 2 402 are in a horizontal straight line.

[0045] See also Figure 6 , multiple connecting seats 605 are fixedly connected to the bottom plate 1 401 and the bottom plate 2 402 respectively, and multiple steel balls 606 distributed equidistantly in a circle are installed inside the connecting seat 605. Multiple steel balls 606 are distributed on the outside of the steel cable 604. The connection method between the multiple steel balls 606 and the steel cable 604 is a rolling connection. The multiple steel balls 606 can reduce the friction between the steel cable 604 and the connecting seat 605. The end of the steel cable 604 away from the roller 603 is fixedly connected to a fixing rod 607. The fixing rod 607 cooperates with the roller 603 to straighten the steel cable 604. The outer side of the fixing rod 607 is fixedly sleeved with multiple fixing frames 608 distributed equidistantly, and the fixing frames 608 are fixedly connected to the protective frame 2.

[0046] In this embodiment, when the bottom plate 1 401 or the bottom plate 2 402 moves upward due to the obstruction of an obstacle, the bottom plate 1 401 or the bottom plate 2 402 moves upward to pull the steel cable 604 through the connecting seat 605, so that the roller 603 rotates to release the wire. When the bottom plate 1 401 or the bottom plate 2 402 fails to completely return to its original position under the drive of the spring 403, the central control of the car can still receive the warning issued by the laser receiver 702. At this time, the car driver controls the dual-axis motor 601 to operate, and the dual-axis motor 601 drives the roller 603 to rotate and rewind the steel cable 604. In the process of the roller 603 rewinding the steel cable 604, the steel cables on the outer sides of the multiple bottom plates 1 401 and the two bottom plates 2 402 are rewound. The cable 604 is gradually straightened. During the straightening process of the cable 604, the cable 604 drives the multiple bottom plates 1 401 and the two bottom plates 2 402 to be located on the same horizontal line through the connecting seat 605. At this time, the sealing strip 1 406 and the sealing strip 2 407 between the bottom plate 1 401 and the bottom plate 2 402 abut against each other, and the two sealing strips 1 406 between the two bottom plates 1 401 abut against each other. The top plate 405 at the upper ends of the bottom plates 1 401 and the bottom plates 2 402 abut against the sealing gasket 8 at the upper end of the bracket 1, so that the bottom plate structure 4 and the bracket 1 have good sealing performance, avoiding the existence of gaps between the sealing strips due to incomplete resetting of the bottom plate 1 401 or the bottom plate 2 402.
