[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0039] The following will be described in conjunction with Figures 1 to 6 , the embodiments of the present utility model.

[0040] According to an embodiment of the present utility model, on the one hand, a storage device for storing lithium batteries 9 is provided, including: a placement box 1, a plurality of placement racks 2, and a driving component 3. The interior of the placement box 1 has an accommodation space 101. The plurality of placement racks 2 can be folded along the vertical direction, and the interior has a placement space for placing the lithium batteries 9. The plurality of placement racks 2 are arranged in the accommodation space 101 and are assembled and connected in sequence along the vertical direction. The placement rack 2 has an unlocked state that can be folded or unfolded along the vertical direction, and a locked state that maintains the unfolded state. The driving component 3 is arranged in the placement box 1 and is connected to the placement rack 2 near the top of the accommodation space 101. The driving component 3 is adapted to drive the placement rack 2 to move along the vertical direction.

[0041] Applying the storage device of this embodiment, a plurality of placement racks 2 are stacked and placed inside the placement box 1. Each placement rack 2 can place a plurality of lithium batteries 9. A single placement box 1 can store a large number of lithium batteries 9 in the vertical space. Compared with a single tray 8, the number of stored batteries is more and it is more convenient for classified storage. The entire placement box 1 can be transferred simultaneously through a transfer device, which can greatly improve the handling efficiency of the lithium batteries 9. In addition, since a driving component 3 is provided inside the storage device, when taking the lithium batteries 9 out of the placement box 1, it can be carried out sequentially from bottom to top along the vertical direction. After the lithium battery 9 at the bottom is taken out, the placement rack 2 is changed to the unlocked state, and the driving component 3 drives the placement rack 2 at the top to move downward, so that the placement rack 2 at the bottom can be folded, thereby reducing the height of the upper placement rack 2 and making it more convenient for the operator to take the lithium batteries 9 on the top placement rack 2, effectively solving the problem that the existing storage and handling methods of lithium batteries are not convenient for management and have low efficiency.

[0042] Among them, it should be noted that the vertical direction refers to Figure 1 the direction of "vertical" indicated by the arrow in

[0043] Specifically, there is no limitation on the specific folding form of the placement rack 2. It can be a folding form of a plug and a sleeve telescoping, or a folding form of a connecting rod, or a folding form of a slider and a guide rail, and can be flexibly selected according to requirements.

[0044] In this embodiment, the placement rack 2 includes a top plate 201, a connecting component, a bottom plate 202, and a locking component. The connecting component includes a plurality of connecting rod groups. The connecting rod group includes a first connecting rod 203 and a second connecting rod 204 that are hinged. The upper end of the first connecting rod 203 is hinged to the edge of the top plate 201, and the lower end of the second connecting rod 204 is hinged to the edge of the bottom plate 202. The locking component is arranged on the connecting component and is in locking cooperation with the connecting component. The structure of the placement rack 2 is simple and reliable, and folding and unfolding can be achieved by the swinging of the components in the connecting component.

[0045] Specifically, as Figure 3 andFigure 4 As shown, the top plate 201 and the bottom plate 202 are rectangular plates, and the positions near the four corners of the top plate 201 and the bottom plate 202 are connected by a connecting rod group to ensure the stability of the support; when folded, the first connecting rod 203 and the second connecting rod 204 are bent toward the inside of the placement space, avoiding the first connecting rod 203 and the second connecting rod 204 from bending outward and interfering with the placement box 1, thereby effectively improving the utilization rate of the internal space of the placement box 1. In addition, the first connecting rod 203 and the second connecting rod 204 are bent toward the inside of the placement space, which can also effectively reduce the space required for the placement rack 2 when in use, and can reduce the width of the placement box 1.

[0046] In this embodiment, a slide groove 2041 is provided on the outer wall of the second connecting rod 204, and the slide groove 2041 extends from the hinge rotation center of the lower end of the second connecting rod 204 along the extension direction of the second connecting rod 204. The locking assembly includes a shift rod 205, and the shift rod 205 cooperates with the slide groove 2041 through a slider provided on its own outer wall. The shift rod 205 slidably cooperates with the slide groove 2041 of at least two adjacent second connecting rods 204 on the same side. When the shift rod 205 moves to the bottom of the slide groove 2041, the first connecting rod 203 and the second connecting rod 204 can be swung, folded or unfolded. When the placement rack 2 is in the unfolded state, the shift rod 205 is moved upward to disengage from the bottom of the slide groove 2041, and a support can be formed between the second connecting rod 204, thereby preventing the second connecting rod 204 from swinging and folding. The operator can switch the placement rack 2 between the locked state and the unlocked state by toggling the shift rod 205. The locking method is simple and effective, and is easy to process and manufacture.

[0047] Specifically, in order to enable the gear lever 205 to maintain its current position in the slide groove 2041, an anti-skid layer or an anti-skid pad is provided on the slider surface of the gear lever 205 to increase the friction between the slider and the slide groove 2041, so that the gear lever 205 can maintain its current position and prevent the gear lever 205 from falling automatically.

[0048] Furthermore, the lever 205 is arranged on the side of the storage box 1 where the door body is arranged or the open side. When the lever 205 is lifted, the function of restraining the lithium battery 9 can be realized, which can effectively prevent the battery from slipping due to uneven ground or during transportation.

[0049] In this embodiment, the driving assembly 3 includes a driving member 301, a rotating cylinder 302, and a connecting rope 303. The driving member 301 is disposed at the top of the accommodating space 101 and is adapted to drive the rotating cylinder 302 to rotate. One end of the connecting rope 303 is connected to the circumferential surface of the rotating cylinder 302, and the other end is connected to the top plate 201 of the corresponding placement rack 2. The driving method is simple and reliable. The placement rack 2 can be lifted or lowered by pulling the connecting rope 303 through the rotating cylinder 302. In addition, when the rotating cylinder 302 rotates to lower the connecting rope 303, the placement rack 2 folds itself under the action of gravity, which can prevent the driving assembly 3 from forcibly driving the placement rack 2 to move and damage the placement rack 2 when the placement rack 2 gets stuck, thus improving safety.

[0050] It can be understood that as an alternative embodiment, the driving assembly 3 can also be a telescopic cylinder, and the telescopic end of the telescopic cylinder drives the top plate 201 of the placement rack 2 to move vertically.

[0051] Specifically, as Figure 2 shown, the driving assembly 3 further includes a rotating frame 304 and a mounting frame 305. The rotating cylinder 302 is rotatably disposed at the top of the accommodating space 101 through the rotating frame 304, and the driving member 301 is disposed at the top of the accommodating space 101 through the mounting frame 305. The driving end 3011 of the driving member 301 is assembled and connected to the rotating cylinder 302 and can drive the rotating cylinder 302 to rotate. The connecting rope 303 is wound around the outer circumferential surface of the rotating cylinder 302, and one end of the connecting rope 303 is fixedly connected to the connecting rod of the top plate 201 of the placement rack 2.

[0052] Preferably, the driving member 301 is a driving motor.

[0053] It should be noted that in order to increase the driving force of the driving member 301, necessary speed reduction and torque increase components such as a speed reducer are also included.

[0054] In this embodiment, an operation panel 4 is further included. The operation panel 4 is connected to the driving assembly 3. The operation panel 4 has a timing unit and a display unit. The operation panel 4 can display the putting-in time of the lithium battery 9. The operator can control the start and stop of the driving assembly 3 through the operation panel 4, and the operation structure is simple and reliable.

[0055] In this embodiment, a temperature detection member 5 and an alarm assembly 6 are further included. The temperature detection member 5 is disposed in the accommodating space 101 and is connected to the operation panel 4. The alarm assembly 6 is disposed on the outer wall of the placement box 1 and is connected to the operation panel 4. The operation panel 4 can display the temperature inside the placement box 1. When the set storage time on the operation panel 4 is met or the preset safe temperature is exceeded, the alarm assembly 6 can give an alarm in time to remind the operator. This can not only remind the operator to pick up the battery in time, but also remind the operator to check when there are large abnormal temperature fluctuations.

[0056] Specifically, the operation panel 4 can set the storage time of the storage battery, and can choose to set the storage time for each layer of the placement rack 2 or the entire placement box 1. When the storage time is completed, the operator can be reminded to take the battery in time. In addition, the temperature detection component 5 can real-time feedback the ambient temperature inside the placement box 1, and when the ambient temperature is abnormal, the operator can understand and handle it in time.

[0057] In this embodiment, a pulley assembly 7 is further included. A plurality of pulley assemblies 7 are provided at the bottom of the placement box 1. The pulley assembly 7 has a rotatable moving state and a non-rotatable fixed state. Through the pulley assembly 7, the operator can easily and labor-savingly push the placement box 1 to move, reducing the moving burden of the placement box 1.

[0058] Specifically, the pulley assembly 7 includes a universal wheel 701 and a brake pad 702. The universal wheel 701 can randomly change the moving direction when the placement box 1 moves, facilitating the operator to push and transfer. The brake pad 702 can lock the universal wheel 701, making the universal wheel 701 unable to rotate, preventing the placement box 1 from moving randomly due to external force when it is stationary, and improving the safety of the placement box 1;

[0059] In this embodiment, the placement box 1 includes a main box 102, a shock-absorbing pad 103 and a bearing platform 104. The main box 102 has an accommodation space 101. The bearing platform 104 is located at the bottom of the main box 102, and the shock-absorbing pad 103 is located between the placement box 1 and the bearing platform 104. When the placement box 1 is transported, it can play a shock-absorbing role, effectively protecting the main box 102 and the lithium battery 9 inside, and can avoid the situation that the battery shakes violently inside the main box 102 during the transportation process.

[0060] Among them, the specific type of the shock-absorbing pad 103 is not limited, and it can be a rubber pad, a plastic pad, etc., as long as it can play a shock-absorbing role.

[0061] In this embodiment, a tray 8 placed on the top surface of the bottom plate 202 is further included. The placement rack 2 further includes rollers 206 provided on the top surface of the bottom plate 202. The tray 8 has a plurality of placement grooves 801 that are spaced apart and open upward. The placement grooves 801 are used to place the lithium battery 9. The placement grooves 801 can effectively restrict the position of a single lithium battery 9, preventing adjacent lithium batteries 9 from contacting. In addition, when the tray 8 moves, it cooperates with the rollers 206, which can reduce the friction when the tray 8 moves, making it more convenient to extract and move the tray 8.

[0062] Specifically, the specific type of the rollers 206 is not limited, and the one-way rollers 206 can be spherical rollers that can rotate in any direction.

[0063] Further, as Figure 3 and Figure 4As shown, a plurality of rollers 206 are spaced on the top surface of the bottom plate 202 to facilitate uniform cooperation with the bottom surface of the tray 8.

[0064] In this embodiment, a plurality of placement slots 801 are arranged in an array. The tray 8 is provided with a plurality of heat dissipation channels 802 along the horizontal and vertical directions. The plurality of placement slots 801 along the horizontal and vertical directions are connected through the heat dissipation channels 802. The heat dissipation channels 802 can accelerate the rapid diffusion of the ambient temperature to the surface of each battery. When the trays 8 are stacked together for storage, the heat of the lithium batteries 9 can also be dissipated outward, which is more convenient for the storage process of the batteries.

[0065] Among them, the horizontal direction refers to Figure 5 the "horizontal" direction indicated by the arrow in Figure 5 and the vertical direction refers to

[0066]

[0067] Specifically, the cross-sectional shape of the heat dissipation channel 802 is not specifically limited and can be rectangular, circular, triangular or other shapes as long as it is convenient for heat transfer.
