when the battery is required to be overhauled or replaced, the drawing plate 3 is drawn out, at this moment, because the metal spring sheet 10 clamps the metal sheet 6, the movable slide bar 8 and the storage battery 4 synchronously move outwards, the push-pull rod 1307 drives the L-shaped clamping plate 1305 to move, further, the push-pull rod 1303 is driven by the telescopic rod to rotate along the fixed shaft 1302, the pulling piece of the air switch 12 is pushed downwards, at this moment, the air switch 12 is disconnected, the air switch 12 has an arc extinguishing effect, no electric spark is generated when the power is off, the power is safer, after the electric connection between the storage battery 4 and the energy storage box 1 is cut off, the drawing plate 3 is continuously drawn outwards, the movable slide bar 8 moves to the limit position, the metal spring sheet 10 is separated from the metal sheet 6, at this moment, the circuit on the storage battery 4 is not connected, no electric spark is generated, the operation is safer, the maintenance or the battery replacement can be carried out after the drawing plate 3 is drawn out, the maintenance is finished, and the storage battery 4 is put into the placing groove 1402, the limiting block 1406 is pressed into the groove 1306, then the pulling plate 3 is pushed inwards, the extrusion block 1106 abuts against the triangular groove 1108, so that the moving slide bar 8 cannot move, when the metal sheet 6 is completely inserted between the two metal elastic sheets 10, the moving rod 1102 is pushed to move inwards, the extrusion rod 1104 is separated from the extrusion block 1106, the extrusion block 1106 loses the support of the extrusion rod 1104 and is separated from the triangular groove 1108, then the moving slide bar 8 can shrink into the fixed sleeve 7, the metal elastic sheets 10 and the metal sheet 6 are tightly connected before being electrified, no electric spark is generated when the circuit is not connected, when the metal elastic sheets 10 and the metal sheet 6 are rubbed, the pulling plate 3 continues to move inwards, the push-pull rod 1307 slides along the long groove 1312 after contacting with the limiting rod 1309, stops moving after contacting with the limiting block 1406, then pushes the limiting rod 1309 forwards, when the air switch 12 is turned on, the power can be completed, an operator does not need to control the switch in the whole process, the operation is more convenient and safer, in addition, when the limiting rod 1309 moves to the middle position of the limiting groove 1311, the two magnetic blocks are nearest to each other, when the limiting rod 1309 passes through the middle position, under the repulsive acting force of the two magnetic blocks, the limiting rod 1309 can rapidly move towards the other end of the limiting groove 1311, in addition, the push-pull rod 1307 can move in the long groove 1312, the rapid movement of the limiting rod 1309 cannot be blocked, and accordingly the air switch 12 can be turned on and off more rapidly and is turned off, and the power on and off safety is improved.
In summary, by the triggering mechanism 13, before the storage battery 4 is installed or removed, the air switch 12 is automatically turned on and off rapidly, so that the maintenance process is more convenient and safer;
through the fastening mechanism 11, electric sparks are prevented from being generated when the storage battery 4 is electrified, meanwhile, the connection strength of the storage battery 4 is improved, and the safety of the storage battery 4 in the installation and use processes is further improved;
by the safety mechanism 14, the air switch 12 is not turned on under the condition that the storage battery 4 is not stored, the service life of the air switch 12 is prolonged, and the practicability of the device is improved.
While the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes may be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
