[0030] Reference Figure 1-Figure 3 A lithium battery transportation device includes: a frame 100 for accommodating a battery body 10; a blocking device 200, which is arranged above the frame 100 and can move relative to the frame 100; the blocking device 200 can block the liquid injection port 11 on the battery body 10.

[0031] A battery receiving slot for receiving the battery body 10 may be provided on the frame 100 , or the frame 100 may receive the battery body 10 by providing a buckle for snapping the battery body 10 or providing a magnet for adsorbing the battery body 10 .

[0032] like Figure 3 , Figure 4 By using the lithium battery transportation device of the present invention, during the transportation of the lithium battery, the blocking device 200 can be controlled to move downward to block the liquid injection port 11 on the battery body 10. When the lithium battery needs to be taken out, the blocking device 200 can be controlled to move upward to release the blocking of the liquid injection port 11. During the entire transportation process, since the liquid injection port 11 is blocked, the electrolyte is difficult to splash out.

[0033] Among them, since the blocking device 200 is located above the battery receiving slot 110, during the transportation process, the blocking device 200 can also block the liquid filling port 11 and play a role in fixing the battery body 10.

[0034] Among them, the blocking device 200 can move relative to the frame 100 in a variety of ways, such as setting a slide rail on the bracket and setting a slide groove that cooperates with the slide rail on the blocking device 200; or setting an electromagnet on the frame 100, and controlling the movement of the blocking device 200 by controlling the magnetic force of the electromagnet; or manually driving the blocking device 200 to block the liquid filling port 11 on the battery body 10.

[0035] Preferably, the movement of the blocking device 200 relies on the lifting of the push rod 340 to open the blocking device 200, and the push rod is disengaged from 340, and the tension spring 360 pulls the blocking device 200 back and blocks the liquid injection port.

[0036] It should be noted that the blocking device 200 may be connected to the frame 100 and move relative to the frame, or the blocking device 200 may be disposed on the battery body 10 to block the liquid injection port 11 without being connected.

[0037] Here, the sealing device 200 can also seal the liquid injection port 11 in a variety of ways, such as providing a rubber plug on the sealing device 200 to block the liquid injection port 11, or using a magnetic suction piece with a similar shape to the liquid injection port 11 to abut against the outer wall of the liquid injection port 11 so that the liquid injection port 11 is blocked.

[0038] like Figure 3 , Figure 5 In order to facilitate the operation of the blocking device 200, a driving device 300 for driving the blocking device 200 to block the liquid injection port 11 or release the blockage can be set on the frame 100; wherein the driving device 300 can realize the operation of the blocking device 200 through various methods such as a cylinder, a hydraulic piston, etc., and can also control the anti-blocking device by manually operating the driving rod by setting a driving rod.

[0039] like Figure 5 As shown, in order to make the movement trajectory of the blocking device 200 a curve, so that the blocking device 200 can avoid the movement path of the battery removal when contacting the blockage, thereby facilitating the battery removal, the driving device 300 includes a first connecting rod 310 and a second connecting rod 320 rotatably connected to the frame 100, and also includes a third connecting rod 330 connected to the blocking device 200, and the third connecting rod 330 is rotatably connected to the first connecting rod 310 and the second connecting rod 320; the operation of the blocking device 200 is controlled by a planar four-bar mechanism.

[0040] Furthermore, in order to prevent the blocking device 200 from rotating during the rising or falling process, the first connecting rod 310, the second connecting rod 320, the third connecting rod 330 and the frame 100 form a parallelogram connecting rod mechanism; at this time, the third connecting rod 330 always maintains linear motion during the movement, ensuring that the blocking device 200 will not rotate, causing the electrolyte adhered to the blocking device to splash and volatilize, polluting the environment.

[0041] In order to realize automatic control of the blocking device 200, the driving connecting rod 340 can be driven and connected to the first connecting rod 310, specifically, as follows: Figure 5 As shown, the driving connecting rod 340 is drivingly connected to the first connecting rod 310 via the rotating shaft 350, and the rotating shaft 350 is rotationally connected to the frame 100. The end of the driving connecting rod 340 away from the first bracket can be connected to the cylinder, and the driving connecting rod 340 is rotated by the movement of the cylinder piston.

[0042] In order to avoid the dead point of the planar four-bar mechanism, the extending direction of the driving connecting rod 340 is not parallel to the extending direction of the first connecting rod 310 .

[0043] like Figure 1-Figure 3 As shown, in order to prevent the driving device 300 from causing additional bending moment to the blocking device 200 , at least two driving devices 300 are connected to the blocking device 200 ; specifically, the two driving devices 300 are respectively arranged on both sides of the frame 100 .

[0044] like Figure 1 , Figure 5 As shown, an elastic member 360 is provided on the frame 100, and the elastic member 360 is connected to the blocking device 200, and the elastic member 360 provides a force that causes the blocking device 200 to abut against the liquid filling port 11; during transportation, the elastic force provided by the elastic member 360 can cause the blocking device 200 to be pulled, so that the blocking device 200 firmly abuts against the battery; specifically, the elastic member 360 is a spring, and the spring connects the frame 100 and the second connecting rod 320, and the second connecting rod 320 is pulled by the spring, so that the blocking device 200 abuts against the battery, thereby blocking the liquid filling port 11.

[0045] It is understandable that the blocking device 200 can also provide a force to abut against the liquid injection port 11 by its own weight, and in this case, the elastic member 360 is not required to provide elastic force.

[0046] Specifically, Figure 1 As shown, a plurality of sealing plugs 210 are provided on the sealing connecting rod 220, and a plurality of battery receiving slots 110 are provided on the frame 100. The plurality of sealing plugs are used to seal a plurality of liquid injection ports 11 of a plurality of battery bodies 10 in the plurality of battery receiving slots 110; when the sealing device 200 moves downward, the liquid injection holes of a plurality of battery bodies 10 can be sealed at the same time.

[0047] like Figure 1 , Figure 2 As shown, the lithium battery transportation device includes at least two sealing devices 200, and a plurality of battery receiving slots 110 are arranged on the frame 100; specifically, two rows of battery receiving slots 110 are arranged on the frame 100, a sealing device 200 is arranged above each row of battery receiving slots 110, and driving devices 300 are arranged on both sides of each sealing device 200.

[0048] Among them, in order to enhance the compatibility with batteries with different injection port positions, a slide groove can be set in the third connecting rod 330, and the blocking connecting rod 220 part cooperates with the slide groove. The position of the blocking connecting rod 220 in the slide groove can be adjusted according to the needs of different injection port positions to ensure the effectiveness of the blocking device.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
