[0059] In summary, the working principle of a battery cell safety structure provided by an embodiment of the present invention is: during the driving process of a new energy vehicle equipped with a battery cell 2, since the general battery cell 2 is installed at the bottom of the vehicle, it is easy for the battery cell 2 to be lifted up and damaged by stones or other obstacles due to the bottom support during driving. Therefore, in the embodiment of the present invention, firstly, by setting the impurity removal component 5, when the vehicle is driving, by starting the motor 504, the conveyor belt 501 can be driven to rotate, and the conveyor belt 501 can drive multiple impurity removal plates 503 to rotate, and the impurity removal plates 503 can take away impurities at the bottom of the vehicle body by rotating, so that the impurity removal component 5 can actively remove impurities at the bottom of the vehicle, and prevent these impurities from being pushed to the bottom side of the battery cell protective shell 1, thereby fully protecting the safety of the battery cell 2;

[0060] Secondly, if the car is supported on the bottom, so that the impurity removal component 5 is damaged, first of all, the buffer bag 6 can play a buffering role, which can further protect the safety of the battery cell 2. At the same time, if the bottom plate 11 is broken, the broken material will puncture the buffer bag 6. At this time, the self-repairing material in the buffer bag 6 can flow out and seal the gap. In rainy and snowy weather, or when the car is wading, it can prevent water from entering the battery cell protection shell 1 and causing the battery cell 2 to short-circuit. In addition, when the bottom plate 11 is broken, the installation component 4 can be pushed open, so that the installation frame 401 moves, and the installation frame 401 moves through the extrusion block 403 in the limiting groove 402, so as to ensure that the installation frame 4 01 is restricted to only vertical movement, and the mounting frame 401 can timely push out the locking assembly 8 through vertical movement to ensure the operation of the opening assembly 7; when the mounting frame 401 is pushed open, the mounting frame 401 can lead the two push rods 803 to move, and the two push rods 803 can push out the locking frame 801, so that the two connecting strips 702 can be unlocked. At this time, under the resilience of the reset spring 707, the two connecting strips 702 can be reset, and the connecting strip 702 can drive the cover 703 to open, so that the battery cell 2 can obtain sufficient space for upward movement, while avoiding collision with the cover 703, thereby avoiding further loss;

[0061] Furthermore, at the same time, when the connecting strip 702 moves, the driving plate 901 can be driven to move, the driving plate 901 drives the tooth plate 905 to move, the tooth plate 905 can drive the gear 904 to rotate, the gear 904 drives the ejection rod 906 to rotate through the adapter shaft 903, and the ejection rod 906 can push the plug out to achieve the purpose of disconnecting the socket 3. The plug on the socket 3 can be pushed out by the ejection component 9 to avoid the problem of burning the circuit of the entire vehicle body caused by a short circuit;

[0062] In addition, it should be emphasized that when the power shaft 505 rotates, the power shaft 505 can drive the power rod 1005 to rotate, and the power rod 1005 drives the push-pull rod 1004 to rotate by connecting the rotating shaft 1006. The push-pull rod 1004 can drive the swing shaft 1003 to swing, and the swing shaft 1003 can drive the cleaning scraper 1001 to swing. When the power shaft 505 rotates one circle, it can drive the cleaning scraper 1001 to swing back and forth once, which can effectively avoid mutual interference between the cleaning scraper 1001 and the debris removal plate 503.

[0063] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
