The water tank 30 contains a solution for extinguishing fire, and illustratively, the water tank 30 contains water, and the solution in the water tank 30 can perform a fire extinguishing process on the charging device 40 dropping into the water tank 30 when the charging device 40 is thermally runaway, so as to prevent the thermal runaway from spreading.

Fig. 4 is a schematic structural view of the charging device 40 of the battery charging and power-exchanging cabinet 01 provided by the embodiment of the present invention, fig. 5 is a schematic partial structural view of the charging device 40 of the battery charging and power-exchanging cabinet 01 provided by the embodiment of the present invention, fig. 6 is a schematic partial structural view of the charging device 40 of the battery charging and power-exchanging cabinet 01 provided by the embodiment of the present invention. Referring to fig. 4 to 6, in the present embodiment, the charging device 40 includes a supporting frame 401, a battery compartment 402, a locking mechanism 403, and an ejection mechanism 404.

The supporting frame 401 is disposed in the cabinet 10 and is fastened to the inner wall of the cabinet 10. The interior of the battery compartment 402 forms a chamber that can house the batteries 02. Meanwhile, the battery compartment 402 is movably supported by the support frame 401, and the position of the battery compartment 402 relative to the support frame 401 is locked or unlocked by the locking mechanism 403. When the battery 02 is charged and the thermal runaway of the battery 02 does not occur, the position of the battery compartment 402 is locked by the locking mechanism 403, so that the stability and safety of the charging process of the battery 02 can be ensured. When the thermal runaway occurs in the battery 02, the position of the battery compartment 402 is unlocked by the locking mechanism 403, and at this time, the battery compartment 402 can move relative to the support frame 401 so as to fall into the water tank 30, so that the thermal runaway can be prevented from spreading in the cabinet 10.

In this embodiment, a cross beam 407 is provided in the cabinet 10, the cross beam 407 extends along a left-right direction (i.e., a direction perpendicular to the inside or the outside in fig. 1), and two cross beams 407 are disposed at an interval along a moving direction of the battery compartment 402, an extending direction of each cross beam 407 forms an included angle with the moving direction of the battery compartment 402, both ends of each cross beam 407 are fastened and connected to an inner wall of the cabinet 10, the supporting frame 401 is fixedly disposed in the mounting cavity 103 of the cabinet 10, and is fastened and connected to the cross beam 407, that is, the supporting frame 401 is fastened and connected to the inner wall of the cabinet 10 through the cross beam 407, the cross beam 407 can ensure stability of the supporting frame 401, and the cross beam 407 and the supporting frame 401 can ensure strength of the cabinet 10 together. Of course, in other embodiments of the present invention, the supporting frame 401 may also be directly connected to the inner wall of the cabinet 10, and this embodiment is not limited.

It should be noted that, in the present embodiment, the water tank 30 is disposed behind the charging device 40, and the direction in which the battery compartment 402 moves relative to the supporting frame 401 is a front-to-back direction (i.e., a left-to-right direction in fig. 1). In order to facilitate the movement of the battery compartment 402, the supporting frame 401 is disposed obliquely, and the rear end of the supporting frame 401 is closer to the water tank 30 than the front end, so that the battery compartment 402 can move toward the water tank 30 under the gravity and inertia and fall into the water tank 30 after the position of the battery compartment 402 is unlocked. Of course, in other embodiments, the water tank 30 may also be disposed at a side portion of the charging device 40, and at this time, the battery compartment 402 is correspondingly disposed to be able to move to the side portion to drop into the water tank 30, which is not described herein again.

The ejection mechanism 404 includes at least one top member 419 and at least one resilient member 425. Each top piece 419 is movably disposed on the supporting frame 401 and is engaged with the battery compartment 402. Each resilient member 425 is coupled to at least one top member 419, and each resilient member 425 is configured such that the top member 419 coupled thereto always applies a force to the battery compartment 402 to allow the battery compartment 402 to move relative to the support frame 401 and drop into the water reservoir 30 when the locking mechanism 403 unlocks the position of the battery compartment 402. When the position of the battery compartment 402 is locked by the locking mechanism 403, the top member 419 is constrained between the battery compartment 402 and the supporting frame 401 by the battery compartment 402 being pressed against the elastic force of the elastic member 425, and when the position of the battery compartment 402 is unlocked by the locking mechanism 403, the constraint force of the battery compartment 402 on the top member 419 is cancelled, so that the battery compartment 402 can be driven by the movement of the top member 419 under the action of the elastic member 425 to move the battery compartment 402, so that the battery compartment 402 can move relative to the supporting frame 401 and fall into the water tank 30.

That is, the battery charging and exchanging cabinet 01 enables the top piece 419 to drive the battery compartment 402 with the unlocked position to move towards the water tank 30 under the action of the elastic piece 425 through the arrangement of the ejection mechanism 404, so as to quickly drop into the water tank 30, thereby relieving the problem that the battery compartment 402 drops into the water tank 30 slowly only under the action of self gravity, and preventing thermal runaway from spreading in the cabinet body 10. Meanwhile, as the elastic piece 425 in the ejection mechanism 404 provides driving force for the movement of the top piece 419, the ejection mechanism has low cost and convenient installation and replacement, and can also ensure the working efficiency and quality.

It should be noted that, in order to facilitate the user to put in and take out the battery 02, in the present embodiment, the cabinet 10 is provided with a plurality of openings 101, the plurality of openings 101 correspond to the plurality of charging devices 40 one by one, the battery compartment 402 of each charging device 40 is further provided with an inlet 415 communicated with the cavity, and the inlet 415 of each charging device 40 is opposite to and communicated with the corresponding opening 101. Meanwhile, the battery charging and replacing cabinet 01 further comprises a plurality of shutters 20 corresponding to the plurality of openings 101 one by one, the shutters 20 are movably connected with the cabinet body 10 or the support frame 401 (exemplarily, can be pivotally connected with the cabinet body 10) and used for opening or closing the corresponding openings 101, and when the shutters 20 open the openings 101, a user can take out the batteries 02 in the cavity or put the batteries 02 into the cavity through the openings 101 and the entrance 415.

Of course, in order to ensure the stability when the door 20 closes the corresponding opening 101, the door 20 may be provided with a hook 201, the cabinet 10 or the support frame 401 may be provided with a lock 102, and the hook 201 and the lock 102 cooperate to protect the safety of the battery 02 in the battery compartment 402. When a user needs to perform a charging operation of the battery 02, the lock 102 can be controlled to be separated from the hook 201, so that the door 20 opens the corresponding opening 101, and after the user places the battery 02 into the cavity of the battery compartment 402 through the opening 101 and the entrance 415, the door 20 closes the corresponding opening 101 and drives the hook 201 to be matched with the lock 102. After charging, the lock 102 is controlled to be separated from the hook 201 again, so that the door 20 opens the corresponding opening 101, so that the user can take the battery 02 in the cavity of the battery compartment 402 through the opening 101 and the entrance 415.

It should be further noted that, a sensor (not shown) may also be disposed in the cavity of the battery compartment 402 of the charging device 40 as required, where the sensor includes a temperature sensor for detecting a temperature in the cavity and/or a smoke sensor for detecting a smoke concentration in the cavity, and the battery charging and discharging cabinet 01 is further provided with a control mechanism (not shown) configured to control the locking mechanism 403 to unlock or lock the position of the battery compartment 402 according to a detection signal output by the sensor. Illustratively, the sensor includes a temperature sensor for detecting the temperature in the battery compartment 402, when the temperature is higher than a set value, which indicates that a thermal runaway may occur in the battery 02 of the battery compartment 402, the control mechanism may control the locking mechanism 403 to unlock the position of the battery compartment 402, so that the battery compartment 402 can move relative to the supporting frame 401 and drop into the water tank 30 for fire extinguishing or temperature reduction treatment, so as to substantially prevent the thermal runaway from spreading.

Referring to fig. 1 to 6 again, in the present embodiment, the supporting frame 401 specifically includes two supporting members 405 and a mounting plate 408 disposed between the two supporting members 405. The two supporting members 405 are spaced apart from each other at an angle to the moving direction of the battery compartment 402, and illustratively, the two supporting members 405 are spaced apart from each other in the left-right direction (i.e., the direction inward or outward in fig. 1), and each supporting member 405 has a strip-shaped structure.

On one hand, the locking mechanism 403 and the ejection mechanism 404 are respectively located on two sides of the mounting plate 408, so that the mounting space on two sides of the mounting plate 408 can be fully utilized, and the whole charging device 40 is more compact and reliable in structure. On the other hand, the lock 418 is directly connected to the battery compartment 402, so that the electronic lock 417 locks the battery compartment 402 more reliably, and the stability of the charging operation of the battery 02 can be ensured.

It should be noted that in other embodiments, the structure of the locking mechanism 403 may also be adjusted according to requirements, and for example, the locking mechanism 403 may be configured to include a motor and a limiting member.

When the latch hook of the electronic lock 417 is separated from the latch hook 418, the position of the bin body 412 is unlocked, the pressing force of the battery bin 402 acting on the top piece 419 through the stopper 413 is cancelled, so that the top piece 419 can be driven to rotate around the hinge shaft 426 under the action of the elastic force of the elastic piece 425, the stopper 413 is driven to move, the bin body 412 is driven to move relative to the supporting frame 401, and the battery 02 is driven to fall into the water tank 30 to extinguish a fire, so that the spread of thermal runaway is prevented.

On one hand, the lock 418 is arranged on the stopper 413, so that the locking mechanism 403 can lock the bin body 412 conveniently, and the reliability of the bin body 412 can be improved; on the other hand, the stopper 413 is also used for abutting against the top piece 419, so that one part of the stopper 413 can realize the locking function and the linkage function with the top piece 419, the cost is saved, and the smoothness and the reliability of moving the battery compartment 402 to the water tank 30 are ensured.

Alternatively, each support 405 is provided with a rail 406 extending in the moving direction of the battery compartment 402. The rail 406 may be "U" shaped or "C" shaped. Two support plates 414 of battery compartment 402 correspond to two guide rails 406 one by one, each support plate 414 is provided with at least two rollers 416 arranged at intervals in the front-rear direction, and the roller 416 on each support plate 414 is supported on the corresponding guide rail 406 and can roll along the guide rail 406, so that battery compartment 402 falls into water tank 30 from front to rear, that is, compartment 412 is movably supported on the guide rails 406 of two support members 405 through rollers 416. After the locking mechanism 403 unlocks the position of the battery compartment 402 through the cooperation of the guide rail 406 and the roller 416, the battery compartment 402 can move towards the water tank 30 more smoothly under the driving of the top piece 419, so as to fall into the water tank 30 in time for fire extinguishing treatment, and thus the spread of thermal runaway is prevented.

Referring to fig. 7 to 9 again, in the present embodiment, the top member 419 has a long bar structure, a rod structure or a shaft structure, and has a connecting portion 421 and a driving portion 420. The connecting portion 421 is connected to the elastic member 425, and the driving portion 420 abuts on the stopper 413 of the battery case 402. The hinge shaft 426 is hinged to a portion of the top member 419 between the connecting portion 421 and the driving portion 420, that is, the hinge shaft 426 is located between the connecting portion 421 and the driving portion 420. Illustratively, the hinge hole 423 is opened at a middle position of the top member 419 in the length direction, and the connecting portion 421 and the driving portion 420 are respectively located at two ends of the top member 419 in the length direction.

With this arrangement, when the position of the cartridge body 412 is locked by the locking mechanism 403, the position of the cartridge body 412 relative to the supporting frame 401 is fixed, so that the stopper 413 causes the elastic member 425 to generate an elastic force by pressing the driving portion 420 of the top piece 419. Conversely, when the locking mechanism 403 unlocks the position of the cabin body 412, the pressing force of the stopper 413 on the driving part 420 of the top piece 419 is cancelled, and at this time, the elastic piece 425 can drive the top piece 419 to rotate around the hinge shaft 426 through the connecting part 421, so that the cabin body 412 can be driven by the top piece 419 to move relative to the supporting frame 401 and fall into the water tank 30.

Since the hinge shaft 426 is located at the middle of the top member 419, the rotation of the top member 419 by the elastic member 425 is more smooth and reliable, thereby facilitating the smooth and reliable movement of the battery compartment 402. In other embodiments, the hinge shaft 426 may also be disposed at the end of the top member 419, and at this time, the connecting portion 421 and the driving portion 420 are disposed at the same side of the hinge shaft 426, so as to ensure the stability of the cooperation between the elastic member 425 and the top member 419, and the cooperation between the top member 419 and the stopper 413, which is not described in detail in this embodiment.

The elastic member 425 is a pressure spring, when the locking mechanism 403 locks the position of the bin body 412, the stopper 413 abuts against the ejector 419 to force the ejector 419 to compress the pressure spring, and when the locking mechanism 403 unlocks the position of the bin body 412, the acting force of the stopper 413 abutting against the ejector 419 is cancelled, the pressure spring recovers deformation, the ejector 419 abuts against the stopper 413 and drives the battery bin 402 to move towards the water tank 30 so as to drop into the water tank 30. Under the structure, the mounting groove can be used as a limiting mechanism for the movement of the elastic member 425 and the top member 419, so that the top member 419 can move linearly, and can also be used as a mounting mechanism for the elastic member 425 and the top member 419, and the movement stability and reliability of the elastic member 425 and the top member 419 are ensured.
