[0038] The box door 2 is sealed and slidably connected to the box body 1. A vacuum pump 8 is fixedly provided on one side of the box body 1. The vacuum pump 8 is connected to the inside of the box body 1 through an exhaust pipe. The vacuum pump 8 is used to evacuate the inside of the box body 1 to prevent the battery from catching fire at high temperature.

[0039] The working principle of a household charging box provided by the present invention is as follows:

[0040] When you need to charge the battery, Figure 2 As shown, the pull rod 5 is pulled upward to drive the clamping plate 7 to move upward, so that the clamping plate 7 is disengaged from the clamping slot 4, thereby releasing the restriction on the door 2, and then the door 2 is pulled leftward.

[0041] The box door 2 drives the first toothed plate 9 to move. When the box door 2 moves a certain distance, the first toothed plate 9 contacts the first gear 11, so as not to interfere with the movement of the placement plate 13. The movement of the first toothed plate 9 drives the first gear 11 to rotate, and the first gear 11 drives the first screw rod 10 to rotate. The rotation of the first screw rod 10 drives the placement plate 13 to move outside the box body 1.

[0042] When the placement plate 13 moves, it drives the second gear 24 to move. The second gear 24 drives the second bevel gear 22 to rotate through the rotating rod 23. The second bevel gear 22 drives the first bevel gear 21 to rotate. The first bevel gear 21 drives the second screw rod 14 to rotate. The second screw rod 14 drives the moving plate 15 to move. The moving plate 15 drives the movable plate 18 to move. The movable plate 18 drives the charging spring 19 to move away from the charging pad 20.

[0043] When the box door 2 is fully opened, the distance between the movable plate 15 and the charging pad 20 is the farthest, so it is convenient to put the battery to be charged into the groove on the top of the placement plate 13, and fit one side of the battery with the side of the groove close to the charging pad 20, so that the battery is in contact with the charging pad 20. At the same time, after the box door 2 is opened after charging, the distance between the movable plate 15 and the charging pad 20 is the farthest, which is convenient for taking out the battery.

[0044] Then push the box door 2 to the right, the box door 2 drives the placement plate 13 to move into the box body 1, and the placement plate 13 drives the battery to move into the box body 1. When the box door 2 is completely closed, the battery contacts the charging pad 20. At the same time, the moving plate 15 drives the charging spring 19 on the movable plate 18 to contact the battery. Through the cooperation of the telescopic rod 16 and the second spring 17, batteries of different sizes can be charged.

[0045] When the box door 2 comes into contact with the card plate 7 during the process of closing, the inclined wedge surface at the bottom of the card plate 7 cooperates with the sliding rod of the box door 2 and drives the card plate 7 to move upward, while compressing the first spring 6. When the card plate 7 is aligned with the slot 4, the card plate 7 is inserted into the slot 4 under the action of the restoring force of the first spring 6 to limit the box door 2.

[0046] Insert the plug into the socket 27 and turn on the power to charge the battery. At the same time, the plug drives the circular plate 29 to compress the third spring 30, and the controller causes the electromagnet 32 ​​to generate magnetic force, which generates magnetic force to adsorb and fix the magnetic block on the sliding cylinder 31, thereby preventing the circular plate 29 from being separated from the socket 27 by the elastic force of the third spring 30.

[0047] The vacuum pump 8 is started to evacuate the box 1, so that the box 1 is in a vacuum state to prevent the battery from catching fire due to high temperature during charging. During the battery charging process, when the temperature sensor 25 detects that the temperature in the box 1 reaches a set threshold range, the signal is transmitted to the controller, and the controller controls the alarm light 34 to sound an alarm, which serves as a warning to remind the charging personnel that the battery temperature is high.

[0048] When the temperature sensor 25 detects that the temperature inside the box 1 exceeds the set threshold range and the battery is prone to fire, the temperature sensor 25 transmits a signal to the controller, and the controller cuts off the power to the electromagnet 32. After the electromagnet 32 ​​loses its magnetism, the third spring 30 drives the plug to be pulled out of the socket 27 under the action of the reset force, thereby cutting off the power to the battery to prevent the battery from continuing to be at high temperature.

[0049] When the battery is fully charged, a signal is transmitted to the controller, and the controller controls the electromagnet 32 ​​to cut off the power, so that the battery is no longer charged, thereby avoiding affecting the service life of the battery.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
