[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] To further understand the content of the present invention, the present invention will be described in detail with reference to the accompanying drawings.

[0021] Combined with Figure 1 , a fixing and clamping device for a lithium battery includes a transport box 1 and a box cover 2 movably arranged at the top end of the transport box 1. A fixing component 3 for fixing a storage battery is arranged inside the transport box 1.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Embodiment 1:

[0024] Please refer to Figures 1 - 4 , the fixing component 3 includes a first spring 31 fixedly connected to the bottom end of the inner wall of the transport box 1, a placement plate 32 fixedly connected to the top end of the first spring 31, a placement groove 33 opened on the upper surface of the placement plate 32, a first sponge pad 38 fixedly connected to the top end of the placement groove 33, a support plate 34 fixedly connected to the top end of the placement plate 32, a second spring 35 fixedly connected to one side of the support plate 34 close to the placement groove 33, a fixing plate 36 fixedly connected to one end of the second spring 35, and a second sponge pad 37 fixedly connected to one side of the fixing plate 36 close to the placement groove 33. Place the storage battery on the top end of the placement groove 33. At this time, the second sponge pad 37 is in contact with the side surface of the storage battery, and the second spring 35 is compressed by force. The reaction force generated by the second spring 35 acts on the side surface of the storage battery. Four groups of fixing components 3 are provided, which are firmly fixed on the four sides of the storage battery to fix the storage battery on the top end of the placement groove 33. The design of the first sponge pad 38 and the second sponge pad 37 is convenient for effectively absorbing the vibration and impact of the storage battery during transportation, reducing the physical damage to the lithium battery. The combined use of the first spring 31 and the second spring 35 applies an appropriate pressure to the lithium battery through the elastic force, ensuring that the battery remains stable in the transport box 1 and improving the transport safety.

[0025] One side of the placement plate 32 away from the support plate 34 is fixedly connected with a slider 321. A chute 11 is formed in the inner wall of the transport box 1. The slider 321 is slidably connected with the chute 11. The tightly fitted structure of the chute 11 and the slider 321 provides additional lateral stability support for the placement plate 32, effectively preventing the placement plate 32 and the battery on its top from moving laterally during transportation, and further enhancing the overall stability.

[0026] A first limiting block 4 is slidably connected inside the chute 11. One side of the first limiting block 4 is fixedly connected with a second limiting block 41. A limiting groove 13 is formed at the top of the transport box 1. The limiting groove 13 communicates with the chute 11. A limiting bolt 411 is threadedly connected between the limiting groove 13 and the second limiting block 41. The second limiting block 41 is fitted with the limiting groove 13. The bottom end of the first limiting block 4 is in contact with the top end of the slider 321. The second limiting block 41 is fixed to the limiting groove 13 by the limiting bolt 411. When severe vibration or bump occurs during transportation, the second limiting block 41 is convenient for effectively preventing excessive movement of the slider 321, providing a safer and more stable storage environment for the lithium battery, and reducing the potential damage risk caused by displacement.

[0027] A groove 21 is formed on the lower surface of the box cover 2. A motor 6 is fixedly connected to the top end of the inner wall of the groove 21. The output end of the motor 6 is fixedly connected with a rotating rod 61. One end of the rotating rod 61 is fixedly connected with a mounting seat 611. A fan blade 612 is fixedly connected to the outer surface of the mounting seat 611. The motor 6 drives the rotating rod 61 to rotate, thereby driving the mounting seat 611 and the fan blade 612 to rotate, forming an air flow inside the transport box 1, which is convenient for effectively improving the air circulation inside the box.

[0028] A ventilation opening 12 is formed on the outer surface of the transport box 1. A cleaning block 5 is slidably connected inside the ventilation opening 12. A handle 51 is fixedly connected to the outside of the cleaning block 5. The setting of the ventilation opening 12 helps the air circulation inside and outside the transport box 1, reduces the humidity inside the box, and prevents the battery from getting damp. By sliding the cleaning block 5 through the handle 51, it is convenient to clean the ventilation opening 12, avoid the accumulation of dust and dirt, and keep the air circulation unobstructed.

[0029] A locking bolt 22 is threadedly connected between the transport box 1 and the box cover 2. The transport box 1 and the box cover 2 are fixed by the locking bolt 22, effectively preventing the accidental opening of the box cover 2 during handling, transportation or being impacted by external forces.

[0030] During use, place the storage battery on the top of the placement groove 33. At this time, the second sponge pad 37 is in contact with the side of the storage battery, and the second spring 35 is compressed by the force. The reaction force generated by the second spring 35 acts on the side of the storage battery. There are four groups of fixing components 3, which are firmly fixed on the four sides of the storage battery to fix the storage battery on the top of the placement groove 33. The designs of the first sponge pad 38 and the second sponge pad 37 are convenient for effectively absorbing the vibration and impact of the storage battery during transportation, reducing the physical damage to the lithium battery. The combined use of the first spring 31 and the second spring 35 applies an appropriate pressure to the lithium battery through the elastic force, ensuring that the battery remains stable in the transportation box 1 and improving the transportation safety. Fix the second limiting block 41 to the limiting groove 13 through the limiting bolt 411. At this time, the bottom end of the first limiting block 4 is in contact with the top end of the slider 321. The second limiting block 41 is convenient for effectively preventing the excessive movement of the slider 321, providing a safer and more stable storage environment for the lithium battery, and reducing the potential damage risk caused by displacement. Drive the rotating rod 61 to rotate through the motor 6, thereby driving the mounting seat 611 and the fan blade 612 to rotate, forming an air flow inside the transportation box 1, which is convenient for effectively improving the air circulation in the box. Slide the cleaning block 5 through the handle 51 to facilitate cleaning the ventilation opening 12, avoiding the accumulation of dust and dirt, and keeping the air circulation unobstructed.
