[0034] Specifically, the above-mentioned power-off protection mechanism includes the communication assembly 4 installed in the inner wall of box 1, and the communication assembly 4 is connected between first electricity block 2 and second electricity block 3, so that the circuit is communicated.The communication assembly 4 includes electromagnet 41, first electrode sheet 44 and second electrode sheet 45, electromagnet 41 is electrically connected with first electricity block 2, first electrode sheet 44 is electrically connected with electromagnet 41, second electrode sheet 45 is electrically connected with second electricity block 3, and first electrode sheet 44 and second electrode sheet 45 are oppositely arranged.The magnetic force of electromagnet 41 is proportional to the current through the coil, and the greater the current, the stronger the magnetic force generated.Second electricity block 3 and electromagnet 41 are communicated through first electrode sheet 44 and second electrode sheet 45, and power off when second electrode sheet 45 is away from first electrode sheet 44.

[0035] Further, the above-mentioned power-off protection mechanism further comprises an automatic circuit breaking mechanism 5, which is used to drive the second electrode sheet 45 away from the first electrode sheet 44 when the charger current changes. The automatic circuit breaking mechanism 5 is connected with the second electrode sheet 45, and is used to drive the second electrode sheet 45 away from the first electrode sheet 44 when the charger current changes, so as to disconnect the second electrode sheet 45 from the first electrode sheet 44. The automatic circuit breaking mechanism 5 comprises a magnetic attraction part which is arranged opposite to the electromagnet 41. The automatic circuit breaking mechanism 5 comprises a moving plate 51 which is arranged on the same side of the second electrode sheet 45, and the magnetic attraction part is an iron block 52 which is arranged on one side of the moving plate 51 which faces the electromagnet 41. After the electromagnet 41 generates a magnetic force, the iron block 52 is attracted, so that the moving plate 51 is fixed on the side of the electromagnet 41. The automatic circuit breaking mechanism 5 further comprises two groups of limiting rods 53 which are arranged along the relative moving direction of the first electrode sheet 44 and the second electrode sheet 45. The moving plate 51 is slidably sleeved on the limiting rods 53, and the limiting rods 53 are fixedly connected between the fixed plate 6 and the box body 1. The position of the limiting rods 53 is fixed, so that the moving plate 51 moves stably under the limiting action of the limiting rods 53. A first spring 54 is sleeved and arranged on the limiting rods 53, one end of the first spring 54 abuts against the moving plate 51, and the other end abuts against the inner wall of the box body 1, so that the moving plate 51 has a tendency to move away from the inner wall of the box body 1. The first spring 54 is used to release the elastic force, so that the moving plate 51 moves away from the electromagnet 41 when the magnetic force of the electromagnet 41 changes, so as to cut off the power. One end of the moving plate 51 which is close to the fixed block 42 is fixedly connected with a connecting plate 55, and the connecting plate 55 moves synchronously with the moving plate 51. Four groups of connecting rods 56 are slidably connected in the connecting plate 55, and the four groups of connecting rods 56 are fixedly connected on the sides of the two groups of second electrode sheets 45 which are away from the first electrode sheet 44.

The limiting plate 58 is used to prevent the second electrode sheet 45 from being separated from the connecting plate 55.

[0036] Further, the power-off protection mechanism includes a push rod motor 61 on the side of the automatic circuit breaking mechanism 5 away from the communication assembly 4, which is used to drive the second electrode sheet 45 to approach the first electrode sheet 44, so that the second electrode sheet 45 is in electrical contact with the first electrode sheet 44. The fixed plate 6 is fixedly connected to the inner wall of the box body 1, and the push rod motor 61 is installed on one side of the fixed plate 6. The fixed plate 6 is used to separate the internal space of the box body 1, on the one hand to protect the push rod motor 61, and on the other hand to reduce the moving stroke of the automatic circuit breaking mechanism 5, thereby improving the power connection accuracy. The push rod motor 61 is used to drive the moving plate 51 to approach the electromagnet 41 after being started, so as to facilitate the circuit to be in an open state when charging starts.

[0037] Finally, the power-off protection mechanism further includes two sets of buffer assemblies 7 arranged on the fixed plate 6. The buffer assemblies 7 are used to buffer when the moving plate 51 moves away from the electromagnet 41, so as to prevent the moving plate 51 from directly impacting the fixed plate 6. The buffer assembly 7 includes a buffer plate 71 arranged on the side of the fixed plate 6 close to the moving plate 51. Two sets of buffer rods 72 are fixedly connected to the side of the buffer plate 71 away from the moving plate 51. A third spring 73 is sleeved and installed on the buffer rod 72. The third spring 73 is arranged between the buffer plate 71 and the fixed plate 6, and is used to buffer the impact force when the moving plate 51 is driven to move by the release of the elastic force of the first spring 54. The end of the buffer rod 72 away from the buffer plate 71 penetrates through the fixed plate 6 and is fixedly connected to a limiting disc 74, so as to prevent the buffer plate 71 and the buffer rod 72 from being separated from the fixed plate 6.

[0038] The fixed block 42 is fixedly connected to the inner wall of the box body 1, and the recess 43 is arranged in the fixed block 42. The first electrode sheet 44 is installed in the recess 43, so that the position of the first electrode sheet 44 is fixed. The second electrode sheet 45 moves in the recess 43 under the action of the automatic circuit breaking mechanism 5, away from or close to the first electrode sheet 44. The recess 43 limits the second electrode sheet 45, so as to ensure the relative accuracy of the first electrode sheet 44 and the second electrode sheet 45, thereby improving the power connection accuracy.

At this time, the electromagnet 41 generates a larger magnetic force to adsorb the iron block 52, so that the moving plate 51 is fixed on the side of the electromagnet 41, at the same time, the second spring 57 releases the elastic force to make the second electrode sheet 45 tightly contact with the first electrode sheet 44. After starting charging, the push rod motor 61 is retracted, only the magnetic force of the electromagnet 41 is used to fix the position of the iron block 52. When the battery is fully charged, the power of the charger is reduced, at the same time, the current in the circuit is reduced, so that the magnetic force of the electromagnet 41 is reduced. At this time, the first spring 54 releases the elastic force to drive the moving plate 51 to be away from the electromagnet 41, at the same time, the connecting plate 55 is driven to be away from the first electrode sheet 44, so that the second electrode sheet 45 is synchronously away from the first electrode sheet 44, automatic power-off is realized.

[0040] The above specific embodiments are only optional embodiments of the utility model, based on the technical scheme of the utility model and the related inspiration of the above embodiments, the person skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
