The inside protection machanism that is equipped with of shell 1, protection machanism includes standing groove 9, standing groove 9 lower wall runs through and is equipped with the pivot, this pivot is the damping pivot, guarantee under the artificial pivoted condition of non-, pivot self can not rotate, the pivot is located the one end fixedly connected with turn-button in standing groove 9, the pivot is located the inside one end fixedly connected with adjusting magnet 10 of shell 1, adjusting magnet 10 is close to the one end and the heteropolar looks of wire magnetic path 19 of movable block 17 and is inhaled, movable block 17 right wall is through a plurality of springs and 13 inner wall elastic connection of control box.

Under initial state, the battery has no inside electric quantity, initiative piece 22 is located and returns die cavity 21 leftmost side, and follower 7 is located and returns die cavity 21 rightmost side, and identification block 12 is located mounting groove 11 rightmost side, and at this moment, identification block 12 shows that the battery electric quantity is zero, and after charging for the battery, the battery internal circuit switches on, and resistance wire 14 begins to release heat, and according to joule law, Q ═ I²Rt, where Q represents the amount of heat generated and I represents the current of the circuit, since the battery is charged with electricity and the current is increased gradually, the amount of heat generated is increased gradually, so that the air at the left end of the magnetic strip 15 is expanded to push the magnetic strip 15 to move right, and when the circuit is turned on, the solenoid valve 23 is also turned onOn the other hand, the magnetic stripe 15 can attract the active block 22 to move right, and it is noted that, at this time, the current passes through the solenoid 16, the solenoid 16 is electrified to generate magnetism, according to the right-hand rule, the upper end of the solenoid 16 is an N pole, and the lower end is an S pole, which is opposite to the magnetic field direction of the magnetic stripe 15, so that, under the action of the reverse magnetic field, the field strength of the integrated magnetic field formed by the magnetic stripe 15 and the solenoid 16 is weakened, that is, the attraction force between the magnetic stripe 15 and the active block 22 is weakened, under normal conditions, the transverse acting force (the direction is right) of the external air pressure on the magnetic stripe 15 is smaller than the transverse component (the direction is left) of the attraction force of the active block 22 on the magnetic stripe 15, the air pressure cannot push the magnetic stripe 15 to move, and the transverse component is weakened after the attraction force, so that the external air pressure can push the magnetic stripe 15 to move, the heat is more and more, and when the electric quantity was full, magnetic stripe 15 moved to the fixed block 20 rightmost end under (not with the movable block 17 contact), and simultaneously, from moving block 7 and moving back the type chamber 20 leftmost end, identification block 12 moved the mounting groove 11 leftmost end, showed that the electric quantity has been full.

When the charging is stopped, the electromagnetic valve 23 is closed, the driving block 22 and the driven block 7 cannot move, the solenoid coil 16 loses magnetism, namely a reverse magnetic field disappears, the temperature at the left end of the magnetic strip 15 gradually decreases, air begins to shrink, and under the condition that other factors are not considered, the air pressure at the right end pushes the magnetic strip 15 to move to the left, however, at the moment, the attraction force between the magnetic strip 15 and the driving block 22 is increased, the force (the left direction) of the air pressure at the right end on the magnetic strip 15 is smaller than the transverse component force (the right direction) of the attraction force of the driving block 22 on the magnetic strip 15, and because the driving block 22 cannot move, the magnetic strip 15 cannot move, and at the moment, the identification block 12 is still located at the.

In the process of using the battery, the current is gradually weakened, when the battery is just used, the circuit is conducted, the electromagnetic valve 23 is opened, the attraction force between the magnetic strip 15 and the active block 22 is reduced, as the air at the left end of the magnetic strip 15 is increased for a required time (the resistance wire 14 releases heat quickly, the required time is short), therefore, the magnetic strip 15 moves left for a distance quickly under the action of the air pressure at the right end, moves right after the temperature at the left end rises (because the time of the process is very short, the display of the battery capacity is not influenced), then the current is gradually weakened according to the reduction of the battery capacity, the heat released by the resistance wire 14 is gradually weakened, the temperature is reduced, the magnetic strip 15 moves left slowly along with the reduction of the temperature at the left end, and attracts the driving block 22 to move left slowly, so that the driven block 7 moves right slowly, further, the identification block 12 is also slowly moved to the right, and the longer the identification block 12 is moved to the right, the weaker the electric quantity is.

When the battery is used for half and stops using, the circuit is disconnected, the electromagnetic valve 23 is closed again, the attraction force between the magnetic strip 15 and the driving block 22 is increased again, the magnetic strip 15, the driving block 22, the driven block 7 and the identification block 7 stop moving, when the battery is used again, the above operations are repeated, the identification block 12 moves leftwards, and when the electric quantity of the battery is used up, the identification block 12 moves to the rightmost end.

When a battery circuit is in fault and short circuit, the heat released by the resistance wire 14 is rapidly increased, the temperature of the left end of the magnetic strip 15 is rapidly increased, the magnetic strip 15 is rapidly pushed to move to the right, the magnetic strip 15 is further contacted with the moving block 17 and pushes the moving block 17 to move to the right, when the moving block 17 moves to the lower end of the adjusting magnetic block 10, the magnetic poles of the adjusting magnetic block 10 opposite to the conductive magnetic block 19 are opposite poles, so the conductive magnetic block 19 is attracted to the adjusting magnetic block 10 to move upwards and separated from a conducting wire, the circuit is disconnected, meanwhile, the moving block 17 moves to the right and can extrude a spring, after a period of time, the temperature of the left end of the magnetic strip 15 is reduced, but the leftward thrust of the spring to the moving block 17 (including the internal conductive magnetic block 19) is smaller than the transverse component force (in the rightward direction) of the attraction of the adjusting magnetic block 10 to the conductive magnetic block 17, namely, the moving block 17 cannot move to the left, that is, the electromagnetic conducting block 19 cannot move to the left end of the adjusting magnetic block 10, so that the electromagnetic conducting block 19 cannot fall to connect the circuit, and further the situation of short circuit again is prevented.

Only after people repair the circuit, the rotating button is rotated to change the magnetic poles of the adjusting magnetic block 10, the magnetic poles of the conductive magnetic block 19 opposite to the adjusting magnetic block 10 are homopolar, the conductive magnetic block 19 falls, the circuit recovers, the moving block 17 moves to the left, the battery is normally used, and then the rotating button is rotated.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
