Description

Technical Field

[0001] The present invention relates to the technical field of storage, and specifically to a lithium battery storage cabinet. Background Art

[0002] In today's energy field, lithium batteries are widely used in various devices due to their high energy density, long service life, environmental protection and many other advantages. Their presence can be found everywhere, from electric vehicles to portable electronic devices. With the sharp increase in the usage of lithium batteries, the replacement and storage of lithium batteries have become a key issue.

[0003] In the prior art, in order to improve space utilization, lithium battery storage cabinets are usually designed in a relatively high style. This design makes the cavities for accommodating lithium batteries in the storage cabinet relatively high. When operators perform lithium battery replacement operations, they face many difficulties and risks. On the one hand, when placing the old battery into the storage cabinet, the operator needs to lift the heavy lithium battery to a relatively high position and then put it into the accommodation cavity. This process places extremely high physical requirements on the operator and is extremely inconvenient to operate. On the other hand, when it is necessary to take out the lithium battery in the storage cabinet, especially for larger and heavier lithium batteries, due to their large own gravity, when leaving the accommodation cavity, a huge downward force will be exerted on the operator. This situation is extremely likely to cause the lithium battery to hit the operator, posing a serious threat to their personal safety. At the same time, if the lithium battery accidentally drops to the ground, it will not only damage the lithium battery itself, affecting its performance and service life, but also bring great potential safety hazards due to possible short circuits, fires, etc. of the lithium battery. Summary of the Invention

[0004] The purpose of the present invention is to provide a lithium battery storage cabinet to solve the problems raised in the above background art.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] The present invention provides a lithium battery storage cabinet, including a cabinet body 1, on which a plurality of accommodation cavities 2 are provided. The accommodation cavities 2 are distributed in a grid pattern on the cabinet body 1. A cabinet door is provided on the accommodation cavity 2, and the cabinet door can be opened through an online program operation, which will not be elaborated here.

[0028] Please refer to Figure 1, on both sides of the cabinet body 1, columns 3 are provided at positions corresponding to multiple accommodating cavities 2. Slide grooves 4 are provided on the surfaces of the two columns 3. Both of the two slide grooves 4 communicate with the inside of the columns 3. And a lead screw 12 is rotatably connected in each of the two columns 3. The lead screw 12 can be rotatably connected in the column 3 through a bearing, which will not be elaborated here. Nut blocks 5 are threadedly connected to both of the two lead screws 12. The two nut blocks 5 are connected by multiple guide shafts 6. The multiple guide shafts 6 are jointly connected to a slider 7. The slider 7 is slidably connected to the multiple guide shafts 6. The part of the slider 7 connected to the guide shafts 6 can be provided with an oil-free bushing or a linear bearing, which will not be elaborated here. A support plate 8 is provided on the slider 7. The support plate 8 and the slider 7 can be bolted or snap-connected.

[0029] Please refer to Figure 2 , a synchronous pulley B15 is provided on one of the lead screws 12, and a synchronous pulley A13 is provided on the other lead screw 12. The synchronous pulley B15 and the synchronous pulley A13 are driven by a synchronous belt A14. The synchronous pulley B15 is a double-layer mechanism. The other layer of the synchronous pulley B15 is connected to a synchronous pulley C16 through a synchronous belt B17. The synchronous pulley C16 and the synchronous pulley B15 are driven. A rocker 11 is provided on the synchronous pulley C16. And in order to protect the synchronous belt A14 and the synchronous belt B17, a protective shell 9 and a housing 10 are provided outside the synchronous belt A14 and the synchronous belt B17 for protection.

[0030] The rocker 11 passes through the housing 10 and extends to the outside. Manually rotate the rocker 11 to drive the synchronous pulley C16 to rotate, drive the synchronous pulley B15 and one of the lead screws 12 to rotate through the synchronous belt B17. At the same time, the synchronous pulley B15 drives the synchronous pulley A13 and the other lead screw 12 to rotate through the synchronous belt A14. The two lead screws 12 rotate synchronously, and the two nut blocks 5 threadedly connected to the two lead screws 12 move, driving the guide shafts 6 and the slider 7 to move upward. At this time, only need to place the lithium battery on the support plate 8 in advance, and then by rotating the rocker 11, the vertical movement of the lithium battery can be realized.

[0031] Since the slider 7 is slidably connected to the guide shafts 6, by pushing the slider 7 by hand, the support plate 8 and the lithium battery can be driven to move horizontally, so that the lithium battery can be moved in front of the corresponding accommodating cavity 2.

[0032] The diameter of the synchronous pulley C16 is smaller than the diameter of the synchronous pulley B15, and the diameter of the synchronous pulley B15 is equal to the diameter of the synchronous pulley A13. Thus, the synchronous pulley B15 and the synchronous pulley A13 can rotate synchronously, and according to the lever principle and the torque balance principle, the synchronous pulley C16 can be driven to rotate with a smaller force, and at the same time, it is also convenient to more precisely control the rising height of the support plate 8.

[0033] The position where the lithium battery moves mainly refers to the position of the opened accommodation cavity 2. The opened cabinet door can be controlled through a mini-program or software, and then drive the pallet 8 and the lithium battery to move through the above method, so as to move the pallet 8 and the lithium battery to the specified position. Moreover, the lead screw 12 and the nut block 5 can be self-locked, so that even if the hand is released, the pallet 8 and the lithium battery will not fall under the action of gravity.

[0034] In order to improve the self-locking ability between the lead screw 12 and the nut block 5, the helix angle of the lead screw 12 and the nut block 5 is generally between 5 and 15 degrees, and the number of thread starts is set between 2 and 4.

[0035] At this time, the lithium battery in the accommodation cavity 2 can be moved onto the pallet 8 to complete the replacement of the lithium battery.

[0036] Embodiment 2, on the basis of the above, in order to make it more convenient to replace the lithium battery in the accommodation cavity 2, the following solution is provided:

[0037] Please refer to Figures 3 to 5 , the pallet 8 is provided with a placement area A81, a connection area 82, and a placement area B83. An old battery label is pasted on the placement area A81, a new battery label is pasted on the placement area B83, and a plurality of rollers 19 are provided on both the placement area A81 and the placement area B83. Through the rollers 19, it is convenient for the lithium battery to slide between the placement area A81, the connection area 82, and the placement area B83.

[0038] A plurality of groups of corresponding slide rails 20 are provided both in the accommodation cavity 2 and on the connection area 82. A placement plate 21 is slidably connected in the accommodation cavity 2. A plurality of rollers 23 are provided on the placement plate 21. The rollers 23 are rollingly connected in the slide rails 20. The placement plate 21 is slidably connected in the accommodation cavity 2 through the rollers 23. A limiting mechanism is further provided between the placement plate 21 and the accommodation cavity 2, which can limit the moving distance of the placement plate 21 to prevent the placement plate 21 from completely moving out of the accommodation cavity 2.

[0039] A plurality of rollers 19 are also provided on the placement plate 21, and a handle 22 is further provided on the placement plate 21 to facilitate pulling the placement plate 21 to move.

[0040] After aligning the pallet 8 with the corresponding accommodation cavity 2, pull out the placement plate 21 through the handle 22. The placement plate 21 slides to the connection area 82 on the pallet 8, and the rollers 23 on the placement plate 21 slide into the slide rails 20 on the connection area 82, which can reduce the friction force.

[0041] The size of the placement plate 21 fits the connection area 82. When the placement plate 21 is stored on the connection area 82, on the horizontal plane, the height of the placement area A81 is equal to the height of the combination of the connection area 82 and the placement plate 21, and the height of the placement area B83 is equal to the height of the combination of the connection area 82 and the placement plate 21.

[0042] In this way, the old lithium battery can be placed on the placement area A81. After moving the pallet 8 and the lithium battery to the corresponding accommodation cavity 2, the placement plate 21 with a new lithium battery (a fully charged lithium battery, the same below) is pulled out through the handle 22, and the placement plate 21 is moved to the connection area 82 and aligned. At this time, the new lithium battery on the placement plate 21 is pulled towards the placement area B83, and then the old lithium battery stored on the placement area A81 is pulled towards the placement plate 21. Then, the placement plate 21 is pushed towards the inside of the accommodation cavity 2, and the placement plate 21 and the old lithium battery are pushed back into the accommodation cavity 2 to complete the storage of the old lithium battery.

[0043] In order to facilitate the corresponding connection between the placement plate 21 and the connection area 82, the slide rail 20 on the connection area 82 can be set to a flared type.

[0044] In addition, corresponding to the height difference between every two accommodation cavities 2 on the same horizontal line, the transmission ratio between the synchronous pulley C16 and the synchronous pulley B15 can be set. Rotating the synchronous pulley C16 five times makes the pallet 8 drive the lithium battery to move by the height of one accommodation cavity 2, facilitating the quick alignment of the pallet 8 with the accommodation cavity 2.

[0045] Guardrails are provided at all ends of the pallet 8 except for the end close to the accommodation cavity, which can limit the lithium battery inside.

[0046] After the lithium battery is replaced, the rocker 11 is shaken in the reverse direction. The synchronous pulley C16 drives the synchronous pulley B15 and one of the lead screws 12 to rotate in the reverse direction through the synchronous belt B17. At the same time, under the drive of the synchronous belt A14, the synchronous pulley A13 and the other lead screw 12 will also rotate in the reverse direction, so that the pallet 8 drives the lithium battery to move downward until it moves to a suitable position and the lithium battery is removed.

[0047] The replacement of the lithium battery is completed, saving the physical strength of the replacement personnel. At the same time, driving the lithium battery to move through the pallet 8 can also avoid the problem of the lithium battery falling caused by manual handling, prevent the lithium battery from falling and being damaged, reduce the occurrence of accidents, and protect the safety of the replacement personnel.

[0048] For the convenience of use, markings are provided on the column 3, and the markings correspond to each layer of accommodation cavity 2, which can facilitate the user to quickly and accurately align the pallet 8 with the placement plate 21.

[0049] A protective brush 18 is provided in each chute 4. The protective brush 18 is arranged on both sides inside the chute 4. When the nut block 5 moves in the chute 4, it will squeeze the protective brush 18, causing the protective brush 18 to deform. Thus, the nut block 5 can slide normally in the chute 4. The part of the protective brush 18 not squeezed by the nut block 5 will stand up. Referring to the scenario of pressing a toothbrush by hand, the inside of the column 3 is isolated from the outside world to prevent external impurities from entering the column 3 and affecting the operation of the structure.

[0050] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention. Any reference signs in the claims should not be construed as limiting the claims involved.
