The working principle is as follows: when the lithium battery protection device is used;
the first step is as follows: when the battery is placed, the top cover 3 is firstly opened, then the blocking ring 26 is held by hands to pass through the inside of the clamping column 5, the lower sliding column 24 and the cone 27 at the lower end of the blocking ring 26 are pressed downwards, when the blocking ring is pressed downwards, the cone 27 can extrude the blocking plate 23 in the clamping slot 25, at the moment, the blocking plate 23 exits from the clamping slot 25, then the clamping plate 6 is moved in the direction of the clamping plate 6 by rotating the clamping plate 6 and the clamping column 5, the opening for placing the battery 7 downwards is opened, then the battery 7 is placed above the battery bottom plate 8 in the placing box 1, then the clamping column 5 and the clamping plate 6 are reset, the blocking ring 26, the lower sliding column 24 and the cone 27 are reset again through the inside of the clamping column 5 in a sliding manner, the blocking plate 23 is clamped in the clamping slot 25 in the clamping column 5 again, so that the clamping plate 6 is pressed downwards again, the clamping plate 6 drives the clamping column 5 to be pressed downwards, and the battery bottom plate 8 upwards extrudes the battery, the clamping plate 23 on the inner part of the sliding opening 22 moves upwards to be clamped at the clamping opening 25, so that the battery is clamped on the surface of the battery bottom plate 8, and the battery 7 is better fixed and more convenient, flexible and simple to disassemble the battery 7 without the fixation of screws in such a way;
the second step is that: when the electric car moves, under the action of the buffer spring 10 fixed on the lower surface of the battery bottom plate 8, the battery 7 is pressed on the clamping groove opening 25 on the clamping column 5 again under the action of inertia force, the clamping plate 23 on the battery bottom plate 8 is pressed on the clamping groove opening 25 again under the action of inertia force, and the shape of the clamping plate 23 is set to be a flat rectangular plate at the upper part and an inclined rectangular plate at the lower part, so that the battery 7 only moves upwards and is pressed and does not slide downwards due to the upward movement of the pressing, and therefore, the battery 7 is more shaken and more tightly pressed above the battery bottom plate 8 in the movement, the battery 7 is not greatly collided in the shaking process, the battery 7 is more and more tightly fastened in the shaking process, and the battery 7 is more stable and cannot collide under the action of the buffer spring 10, so that the service life of the battery 7 is not reduced by external factors;
the third step: after the battery 7 is placed on the battery bottom plate 8, the battery bottom plate 8 and the battery 7 can drive the buffer spring 10 and the pressing column 11 at the lower end of the battery bottom plate 8 to press downwards due to shaking when the electric car moves, so that the battery 7 moves on the battery bottom plate 8 simultaneously due to inertia force under the action of the buffer spring 10, the battery bottom plate 8 extrudes the buffer spring 10 at the moment, the buffer spring 10 is extruded and bounced above the interlayer plate 9, and the collision to the battery 7 can not be caused during the bouncing because the top cover 3 and the battery 7 have a certain distance, so that the battery 7 can not be collided and damaged by the buffer spring 10 during shaking, and thus the problem that the battery 7 can not be effectively fixed and controlled in the traditional battery placing box is well solved, the collision of the battery 7 is caused to cause damage or midway line extrusion fracture, the time is caused to people riding the bicycle, and the like, and the service life and the use of the battery 7 are greatly damaged, so that the collision of the battery 7 in motion is well controlled, the protection of the battery 7 can be well improved, the service life of the battery 7 is prolonged, and the line disconnection caused by the collision in use is reduced;
the fourth step: during shaking, the buffer spring 10 continuously moves up and down, so that the lower pressing column 11 slides up and down in the interlayer plate 9, when the lower pressing column 11 is downwards extruded, the lower pressing column 11 can touch the rocker 15, the rocker 15 is downwards pressed on the fixed column 16 to shake due to the action of the fixed column 16, the rotating shaft 17 and the bottom plate 29 which are arranged below the rocker 15, and after the rocker 15 is downwards pressed, the rocker 15 can reset due to the spring 18 connected between the rocker 15 and the bottom plate 29, so that the rotating shaft 17 continuously rotates in a reciprocating manner, the rotation is well controlled without electric power, shaking is generated by a natural force manner, simplicity and effectiveness are realized, whether the shaking is generated under the conditions that an electric vehicle moves and stops is realized, and the required rotation is well controlled;
the fifth step: when the rotating shaft 17 rotates, the gear 21 on the rotating shaft 17 is driven to rotate, and the bevel gear 19 is driven to rotate left and right under the drive of the gear 21, so that the rotating shaft 13 fixed on the bevel gear 19 is driven to rotate, and the fan blades 14 at the upper end of the rotating shaft 13 are driven to rotate to generate certain wind power, so that the battery 7 is guaranteed to be ventilated by air and the heat of the battery 7 is reduced when in a heating state during operation, and the mode not only saves electric power well, but also promotes an active response to the environment conservation and protection, generates flowing air well, controls the temperature in the placing box 1, prevents the heat from damaging the battery 7, prolongs the service life of the battery 7 and protects the use mode of the battery 7;
and a sixth step: the surfaces of the battery bottom plate 8 and the interlayer plate 9 are provided with the flow openings 12, so that air of the fan blades 14 can enter and exit along with the flow openings 12, the left side and the right side of the placing box 1 are provided with the ventilation openings 4, the positions of the ventilation openings 4 are arranged above the inside of the surface of the placing box 1 and below the outside, when the top cover 3 is covered, the rainproof function can be achieved, heat inside the placing box 1 can be dissipated, external air can enter, when rain falls, rainwater cannot enter the inside of the placing box 1 due to the positions of the ventilation openings 4, the damage to the battery is caused, and the service life of the battery is protected.
