Description

Technical Field

[0001] This utility model relates to the field of storage box technology, and more specifically, to a battery cycle test storage cabinet. Background Technology

[0002] With the rapid development of electric vehicles, aluminum-cased lithium batteries, as a type of rechargeable battery with high specific capacity, long cycle life, and environmental friendliness, are becoming increasingly widely used. During the production process of aluminum-cased lithium batteries, cycle life testing is required. Cycle life refers to the number of cycles a battery can withstand before its capacity drops to a specified value under a certain charge-discharge regime; one charge and one discharge cycle constitutes one cycle. Because cycle life testing is time-consuming, it is necessary to monitor various battery parameters.

[0003] Traditional testing methods involve placing the battery in a test chamber, where the heat dissipation vents are typically fixed. In low-temperature environments, the vents cannot be reduced in size, which can lead to excessive heat loss and excessively low battery temperatures, affecting battery performance. Conversely, in high-temperature environments or under high load conditions, the vents cannot be enlarged, hindering timely heat dissipation and potentially causing the battery temperature to rise continuously, thus affecting the accuracy of battery testing. Utility Model Content

[0004] The present invention aims to solve the technical problems mentioned in the background art and provide a battery cycle test storage cabinet.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery cycle test storage cabinet, comprising: an outer shell, a connecting box provided on one end surface of the outer shell, multiple ventilation openings provided at the connection between the outer shell and the connecting box, a heat dissipation opening provided on the outer surface of the connecting box, an adjustment component provided inside the connecting box, a cover plate slidably connected inside the other end of the outer shell, slide rails provided at the upper and lower ends of one side of the outer shell, sliders provided at the upper and lower ends of the cover plate, the sliders slidably connected inside the slide rails, and a disassembly component provided between the upper right side of the cover plate and the outer shell.

[0006] A further preferred embodiment: the adjustment assembly includes: a lead screw, a slider, a connecting rod, a lead screw, a moving rod, a rotating shaft, and an adjustment plate; the adjustment plate is provided inside the heat dissipation vent, and the two ends of the adjustment plate are fixedly connected to the rotating shaft, which is rotatably connected to the two ends of the heat dissipation vent; the lead screw is rotatably connected inside the connecting box; the slider is threadedly connected to the outer surface of the lead screw; the left and right ends of the slider are fixedly connected to the connecting rod; the right end of the connecting rod is fixedly connected to the upper end of the moving rod; and one end of the inner side of the adjustment plate is connected to the moving rod via a hinge.

[0007] A further preferred embodiment: The disassembly assembly includes: an outer box, an L-shaped pull rod, and a plug rod; the outer box is embedded and connected to the right side of the upper surface of the outer shell, and the plug rod is telescopically connected inside the outer box, with the upper end of the plug rod fixedly connected to the L-shaped pull rod.

[0008] A further preferred embodiment: a limiting block is fixedly connected to the outer surface of the insertion rod.

[0009] A further preferred embodiment: a spring is provided at the upper end of the limiting block, and the spring is wound around the outer surface of the insertion rod.

[0010] A further preferred embodiment: a slot matching the insertion rod is provided on the right side of the upper surface of the cover plate.

[0011] A further preferred embodiment: the upper end of the connecting box is threaded with a rotating rod, and the lower end of the rotating rod is fixedly connected to a lead screw. Beneficial effects

[0012] 1. When simulating a high-temperature environment, the rotating rod can be rotated to make the lead screw rotate, which in turn causes the slider to move the moving rod up and down on the lead screw surface. When the moving rod moves upward, it causes the adjusting plate to rotate and change its angle, thus gradually moving the adjusting plate closer to the vertical position. At this time, the heat dissipation vents will gradually decrease, and the ventilation volume will also gradually decrease. When simulating a low-temperature environment, rotating the rotating rod will move the moving rod downward until the adjusting plate is in a horizontal position. At this time, the heat dissipation vents will reach their maximum, and the ventilation volume will also reach its maximum.

[0013] 2. By setting up the disassembly assembly, when inspecting the battery, pulling the L-shaped lever upwards causes the insertion rod to completely disengage from the slot. At this time, the limiting block will slide within the inner wall of the outer casing, and the spring will be compressed. Then, pulling the cover outwards will allow the cover to slide smoothly out of the casing. During installation, align the sliders at both ends of the cover with the slide rails at both ends of the casing, then push the cover inwards until the left side of the cover is completely flush with the left end of the casing. Release the L-shaped lever; under the spring's rebound force, the insertion rod will insert into the slot, thus braking the cover. This eliminates the need to remove the bolts one by one to remove the cover for inspection, greatly improving work efficiency. Attached Figure Description

[0021] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0022] Please see Figure 1-5 In this embodiment of the utility model, a battery cycle test storage cabinet includes: a shell 1, which serves as the main structure of the entire storage box and is capable of storing cycle batteries. The bottom of the shell 1 has an opening for connecting power lines. A connecting box 3 is disposed on one end surface of the shell 1. Multiple ventilation holes are provided at the connection between the shell 1 and the connecting box 3. A heat dissipation vent 11 is disposed on the outer surface of the connecting box 3 for dissipating heat during battery cycling, simulating temperatures under different working scenarios. An adjustment component is provided inside the heat dissipation vent 11, which can be adjusted according to different environments and working states to achieve flexible control of the heat dissipation effect to adapt to different conditions such as low temperature and high temperature. A cover plate 2 is slidably connected to the inside of the other end of the shell 1, providing a certain degree of protection for the inside of the battery. Slide rails are provided at the upper and lower ends of one side of the shell 1, and sliders are provided at the upper and lower ends of the cover plate 2. The sliders are slidably connected inside the slide rails, allowing the cover plate 2 to slide smoothly inside the shell 1 for easy installation and disassembly. A disassembly component is provided between the upper right side of the cover plate 2 and the shell 1, mainly for convenient and quick disassembly of the cover plate 2 to perform operations such as inspection of internal battery components, thereby improving maintenance efficiency.

[0023] In this embodiment of the invention, the adjustment assembly includes: a lead screw 14, a slider 15, a connecting rod 16, a moving rod 17, a rotating shaft 13, and an adjustment plate 10. The adjustment plate 10 is disposed inside the heat dissipation vent 11. The rotating shaft 13 is fixedly connected to both ends of the adjustment plate 10 and rotatably connected to both ends of the heat dissipation vent 11, providing support and a rotation axis for the rotation of the adjustment plate 10, ensuring that the adjustment plate 10 can stably adjust its angle within the heat dissipation vent 11. The lead screw 14 is rotatably connected inside the connecting box 3, providing the basis for power transmission of the entire adjustment assembly. The rotation of the lead screw 14 drives the movement of other components. The slider 15 is threadedly connected to the outer surface of the lead screw 14, so that the rotation of the lead screw 14 can be converted into the movement of the slider 15. The linear motion is achieved to realize precise displacement control. The connecting rod 16 is fixedly connected to the left and right ends of the slider 15, and transmits the motion of the slider 15 to the moving rod 17, which plays the role of connection and transmission. The right end of the connecting rod 16 is fixedly connected to the upper end of the moving rod 17. The moving rod 17 is connected to one end of the inner side of the adjusting plate 10 through hinges, and the up and down movement of the moving rod 17 is converted into the rotation of the adjusting plate 10, thereby changing the specifications of the heat dissipation vent 11.

[0024] In this embodiment of the utility model, the disassembly assembly includes: an outer box 4, an L-shaped pull rod 5, and a plug rod 6. The outer box 4 is embedded and connected to the right side of the upper surface of the outer shell 1, providing space for the installation and accommodation of other components of the disassembly assembly, while also providing a certain degree of protection. The plug rod 6 is telescopically connected inside the outer box 4, and its telescopic movement cooperates with the slot 7 to fix or unlock the cover plate 2, playing a key role in braking. The L-shaped pull rod 5 is fixedly connected to the upper end of the plug rod 6, facilitating manual operation by the operator. By pulling the L-shaped pull rod, the plug rod 6 is moved, thereby changing the locked state of the cover plate 2. It is a control component that directly interacts with the operator, and its L-shaped design makes it easier to operate.

[0025] In this embodiment of the utility model, the limiting block 8 is fixedly connected to the outer surface of the insertion rod 6. On the one hand, it is fixed to the outer surface of the insertion rod 6, which can limit the extension and retraction range of the insertion rod 6, ensuring that the insertion rod 6 moves within a specific stroke and avoiding excessive extension and retraction that could lead to structural failure or malfunction. On the other hand, during the extension and retraction of the insertion rod 6, the limiting block 8 cooperates with the inner wall of the outer box 4 and other structures to guide and stabilize the movement, ensuring the accuracy and reliability of the insertion rod 6's movement.

[0026] In this embodiment of the utility model, the spring 9 is disposed on the upper end of the limiting block 8 and is wrapped around the outer surface of the insertion rod 6. When the insertion rod 6 is pulled upward, the spring 9 is compressed, and at this time, the spring 9 stores elastic potential energy. When the L-shaped pull rod 5 is released, the spring 9 uses the stored elasticity to push the limiting block 8 and the insertion rod 6 to reset, thereby realizing that the insertion rod 6 automatically inserts into the slot 7 to play a braking role. The arrangement of the spring 9 wrapped around the outer surface of the insertion rod 6 can make the force of the spring 9 more evenly applied to the insertion rod 6, ensuring the stability and reliability of the movement of the insertion rod 6, and also making the whole structure more compact and reasonable.

[0027] In this embodiment of the invention, a slot 7 matching the insert rod 6 is located on the right side of the upper surface of the cover plate 2. The main function of the slot 7 is to cooperate with the insert rod 6. When the insert rod 6 is inserted into the slot 7, it can fix the cover plate 2, ensuring that the cover plate 2 remains stably closed when needed and preventing it from being accidentally opened. The slot 7 is located on the right side of the upper surface of the cover plate 2 to correspond to the position of the insert rod 6, so as to achieve accurate locking and unlocking functions. This positional relationship ensures that the disassembly assembly can effectively perform the function of fixing and loosening the cover plate 2.

[0028] In this embodiment of the utility model, the rotating rod 12 is threadedly connected to the upper end of the connecting box 3, providing a stable installation position and support for the rotating rod 12, enabling it to perform reliable rotation operation on the connecting box 3. The lower end of the rotating rod 12 is fixedly connected to the lead screw 14. When the rotating rod 12 is rotated, the rotational power can be directly transmitted to the lead screw 14, thereby driving the lead screw 14 to rotate, which in turn drives the movement of subsequent related components, realizing the adjustment of the specifications of the heat dissipation vent 11. This connection method ensures the directness and effectiveness of power transmission, reduces energy loss, and makes the entire adjustment process smoother and more precise.

[0029] Working principle: First, when simulating a high-temperature environment, rotating rod 12 causes lead screw 14 to rotate, which in turn causes slider 15 to move moving rod 17 up and down on the surface of lead screw 14. When moving rod 17 moves upward, it causes adjusting plate 10 to rotate and change angle, thus gradually moving adjusting plate 10 closer to the vertical position. At this time, heat dissipation vent 11 will gradually decrease, and ventilation volume will also gradually decrease. When simulating a low-temperature environment, rotating rod 12 causes moving rod 17 to move downward until adjusting plate 10 is in a horizontal position. At this time, heat dissipation vent 11 reaches its maximum, and ventilation volume also reaches its maximum. When repairing the battery, pulling L-shaped lever 5 upward causes insertion rod 6 to... When the cover plate 2 is completely disengaged from the slot 7, the limiting block 8 will slide within the inner wall of the outer box 4, and the spring 9 will be compressed. Then, by pulling the cover plate 2 outward, the cover plate 2 can be smoothly slid out of the outer shell 1. During installation, the sliders at both ends of the cover plate 2 are aligned with the slide rails at both ends of the outer shell 1. The sliders are slidably connected inside the slide rails. Then, the cover plate 2 is pushed inward until the left side of the cover plate 2 is completely attached to the left end of the outer shell 1. After releasing the L-shaped pull rod 5, the insertion rod 6 will be inserted into the slot 7 under the action of the spring 9, thereby braking the cover plate 2. This eliminates the need to remove the bolts one by one to remove the cover plate 2 for maintenance, greatly improving work efficiency.
