Description

Technical Field

[0001] The utility model relates to the technical field of battery transport boxes, in particular to a lithium battery transport box. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. Due to the highly active chemical properties of lithium metal, its processing, storage, and use place very high demands on the environment. With the advancement of science and technology, lithium batteries have become mainstream and can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries, the fifth generation of rechargeable batteries, were introduced in 1996. They offer superior safety, specific capacity, self-discharge rate, and performance-price ratio to lithium-ion batteries. However, due to their inherent high technology and limited transportation requirements, only a few companies in a few countries currently produce these lithium metal batteries.

[0003] In order to solve the above problems, some existing patents have proposed transporting lithium-ion batteries through special battery transport boxes. For example, patent publication number CN214453046U discloses a lithium battery transport box, comprising a box body, wherein the inner bottom wall of the box body is fixedly connected to symmetrical support columns, the right side of each support column is provided with a first through hole, a support rod is placed inside each first through hole, the ends of the two support rods that are away from each other are fixedly connected to a stopper, the outer surface of each support rod is sleeved with a compression spring, the ends of the two support rods that are close to each other are fixedly connected to a protective block, and a support plate is placed inside the box body. This lithium battery transport box can buffer lithium batteries to avoid accidents caused by collisions and vibrations, can cool lithium batteries, and play a role in cooling lithium batteries. It can protect lithium batteries to avoid bumps during transportation, and can allow air to circulate in the transport box while filtering impurities, achieving the effect of avoiding the influence of external factors.

[0004] However, the device in the above patent can only hold one battery. If a large number of batteries need to be transported, multiple devices need to be stacked in the vehicle compartment, which will take up a large amount of space and have low space utilization. In addition, stacking the devices together makes it difficult to ventilate the batteries inside. Therefore, this patent proposes a lithium battery transport box to solve the above problems.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0021] A lithium battery transport box includes a storage rack 1, an exhaust assembly 4, a fixing assembly 9, and a shock-absorbing assembly 5. The size of the storage rack 1 is adapted to that of a freight car. The front side of the storage rack 1 is provided with placement cavities 2 distributed in a rectangular array. The rear walls of the inner cavities of the placement cavities 2 are provided with connecting holes 3. The rear side of the storage rack 1 is provided with exhaust assemblies 4 connected to the connecting holes 3. The bottom walls of the inner cavities of the placement cavities 2 are provided with shock-absorbing assemblies 5. A battery body 8 that fits tightly with the front side of a rubber pad 7 is placed on the top of the shock-absorbing assembly 5. A baffle 6 is fixedly connected to the rear side of the shock-absorbing assembly 5. The front side of the shock-absorbing assembly 5 is provided with a fixing assembly 9 that fits tightly with the front side of the corresponding battery body 8.

[0022] The beneficial effects of adopting the above technical solution are as follows: the storage rack 1 is fixed horizontally and equidistantly in the freight compartment, the air extraction assembly 4 is connected to the outside of the freight compartment, multiple battery bodies 8 are placed on top of the corresponding shock absorbing assembly 5, the fixing assembly 9 is rotated so as to contact the front side of the corresponding battery body 8, and the battery body 8 moves toward the baffle on the top of the corresponding shock absorbing assembly 5 until the back side of the battery body 8 is tightly fitted with the front side of the corresponding rubber pad 7, and then the air extraction assembly 4 is started. As a result, the air around the battery body 8 is extracted to the outside of the freight compartment by the air extraction assembly 4 through the connecting hole 3, so that all batteries can be ventilated. When the freight compartment moves and shakes, the shock absorbing assembly 5 absorbs the vibration by elastic deformation, thereby cushioning the battery body 8 corresponding to the top of the shock absorbing assembly 5. This lithium battery transport box has the advantages of high utilization of compartment space for storing multiple batteries and convenient ventilation of all batteries.

[0023] Furthermore, the exhaust assembly 4 includes a collecting shell 401, an exhaust fan 402 and an exhaust hose 403; the rear side of the storage rack 1 is fixedly connected to the collecting shell 401 which is connected to the connecting holes 3, the left side of the collecting shell 401 is fixedly connected to the exhaust fan 402 whose input end is connected to the collecting shell 401, and the output end of the exhaust fan 402 is fixedly connected to the exhaust hose 403, and the exhaust hose 403 extends to the outside of the freight compartment at one end away from the exhaust fan 402.

[0024] The beneficial effect of adopting the above further solution is that when the exhaust fan 402 is started, the air around the battery body 8 is collected into the collecting shell 401 through the connecting hole 3, and then discharged to the outside of the freight compartment through the exhaust fan 402 and the exhaust hose 403, so that all battery bodies 8 can be ventilated.

[0025] Furthermore, the shock-absorbing assembly 5 includes a shock-absorbing spring 501, a placement plate 502 and a ball 503; the bottom wall of the inner cavity of the placement cavity 2 is fixedly connected with the shock-absorbing springs 501 distributed in four corners, the top of the shock-absorbing spring 501 is fixedly connected with the same placement plate 502, the top of the placement plate 502 is embedded with balls 503 that are movably connected to it and distributed in a rectangular array, the rear side of the placement plate 502 is fixedly connected with a baffle 6, and the top of the ball 503 is placed with the same battery body 8.

[0026] Furthermore, the fixing assembly 9 includes a slide rod 901, a push block 902 and a threaded rod 903; the front side of the placement plate 502 is fixedly connected to the slide rod 901 which is symmetrically distributed on the left and right, and the outer side of the slide rod 901 is slidably connected to the same push block 902, and the rear side of the push block 902 is tightly fitted with the front side of the corresponding battery body 8, and the front side of the push block 902 is threadedly connected to the threaded rod 903 which extends to the front side of the placement plate 502 and is rotatably connected to the placement plate 502.

[0027] The beneficial effect of adopting the above-mentioned further scheme is that the battery body 8 is placed above the ball 503, and the threaded rod 903 is rotated. The force generated by the rotation of the thread drives the push block to move along the slide rod 901 toward the battery body 8. When the rear side of the push block 902 contacts the front side of the battery body 8, the battery body 8 is pushed toward the baffle 6. At the same time, the battery body 8 drives the ball 503 to roll on the top of the placement plate 502 to avoid friction with the bottom of the battery body 8 until the rear side of the battery body 8 is tightly fitted with the front side of the corresponding rubber pad 7. Stop rotating the threaded rod 903 to fix the battery body 8 in the placement cavity. When the freight car moves and shakes, the shock-absorbing spring 501 absorbs the vibration by elastic deformation, thereby cushioning the corresponding battery body 8 above the placement plate 502.

[0028] The working principle of the lithium battery transport box of the present invention is: the first step: fix the storage rack 1 horizontally and equidistantly in the freight compartment, connect the end of the exhaust hose 403 away from the exhaust fan 402 to the outside of the freight compartment, place multiple battery bodies 8 on the top of the corresponding placement plates 502, so that the battery body 8 contacts the ball 503, rotate the threaded rod 903, and the force generated by the rotation of the thread drives the push block 902 to move along the slide rod 901 toward the corresponding battery body 8. When the rear side of the push block 902 contacts the front side of the corresponding battery body 8, it pushes the battery body 8 to move toward the corresponding baffle 6. At the same time, the battery body 8 drives the ball 503 to roll on the top of the placement plate 502 to avoid friction with the bottom of the battery body 8, until the rear side of the battery body 8 is tightly fitted with the front side of the corresponding rubber pad 7, stop rotating the threaded rod 903, and the battery body 8 can be fixed in the placement cavity 2.

[0029] Step 2: Start the exhaust fan 402. The air around the battery body 8 is collected into the collecting shell 401 through the connecting hole 3. Then, it is discharged to the outside of the freight car through the exhaust fan 402 and the exhaust hose 403. All battery bodies 8 can be ventilated.

[0030] Step 3: When the freight car moves and shakes, the shock absorbing spring 501 absorbs the vibration by elastic deformation, thereby cushioning the battery body 8 corresponding to the placement plate 502.
