[0031] In one embodiment of this utility model, such as Figures 1-3 As shown, an adjustable charging and discharging tray for lithium batteries is provided, including a tray body 1, a fixed beam 2, a slide rail 3, a fixed plate 4, a first adjustment component 5, a second adjustment component 6, and a charging and discharging component 7. The fixed beam 2, the slide rail 3, and the fixed plate 4 are all fixedly connected to the tray body 1. The first adjustment component 5 and the second adjustment component 6 are both slidably connected to the slide rail 3. The charging and discharging component 7 is respectively disposed on the fixed plate 4, the first adjustment component 5, and the second adjustment component 6.

[0032] The first adjustment assembly 5 includes a first guide post 51, a first elastic element, and a first adjustment plate 53. One end of the first guide post 51 is connected to the pallet body 1, and the other end is movably inserted through the first adjustment plate 53. The first elastic element is connected to both the pallet body 1 and the first adjustment plate 53, and is movably inserted through the first guide post 51. The first adjustment plate 53 is slidably connected to the slide rail 3 and the fixed beam 2. Two first guide posts 51 and two first elastic elements are provided, with the two guide posts arranged parallel and spaced apart. The first elastic element is a first spring 52, which is fixedly connected to both the pallet body 1 and the first adjustment plate 53, and movably inserted through the first guide post 51. A first pin 54 is provided on the first adjustment plate 53, and the first pin 54 is inserted sequentially into the first adjustment plate 53 and the fixed beam 2. One end of the first guide post 51 is fixed to the pallet body 1, and the other end is inserted through the first adjustment plate 53, providing guidance for the sliding of the first adjustment plate 53, limiting its sliding trajectory (to prevent deviation), and simultaneously providing mounting support for the first elastic element (serving as a carrier for the elastic element). The first elastic element (first spring 52) is sleeved on the first guide post 51, with its two ends connected to the tray body 1 and the first adjusting plate 53, respectively. It applies an elastic force to the first adjusting plate 53 through its own elastic deformation. During adjustment, it can assist the first adjusting plate 53 in resetting, and during charging and discharging, it can buffer the contact pressure between the lithium battery and the adjusting plate (avoiding damage from hard contact). The first adjusting plate 53, as a load-bearing component (such as the first cathode terminal for mounting the charging and discharging assembly 7), can slide along the slide rail 3 and the fixed beam 2, and its position can be adjusted to adapt to lithium batteries of different sizes.

[0033] The second adjustment assembly 6 includes a second guide post 61, a second elastic element, and a second adjustment plate 63. One end of the second guide post 61 is connected to the pallet body 1, and the other end is movably inserted through the second adjustment plate 63. The second elastic element is connected to both the pallet body 1 and the second adjustment plate 63, and movably inserted through the second guide post 61. The second adjustment plate 63 is slidably connected to the slide rail 3 and the fixed beam 2. Two second guide posts 61 and two second elastic elements are provided, with the two guide posts arranged parallel and spaced apart. The second elastic element is a second spring 62, which is fixedly connected to both the pallet body 1 and the second adjustment plate 63, and movably inserted through the second guide post 61. A second pin 64 is provided on the second adjustment plate 63, and the second pin 64 is sequentially inserted into the second adjustment plate 63 and the fixed beam 2. One end of the second guide post 61 is fixed to the pallet body 1, and the other end passes through the second adjustment plate 63, providing guidance for the sliding of the second adjustment plate 63 and limiting its sliding trajectory (to prevent deviation), while also providing mounting support for the second elastic element (serving as a carrier for the elastic element). The second elastic element (second spring 62) is sleeved on the second guide post 61, with its two ends connected to the tray body 1 and the second adjusting plate 63, respectively. Through its own elastic deformation, it applies an elastic force to the second adjusting plate 63. During adjustment, it assists in resetting the second adjusting plate 63, and during charging and discharging, it buffers the contact pressure between the lithium battery and the adjusting plate (avoiding damage from hard contact). The second adjusting plate 63, as a load-bearing component (such as the second cathode terminal 72 for mounting the charging / discharging assembly 7), can slide along the slide rail 3 and the fixed beam 2, and its position can be adjusted to accommodate lithium batteries of different sizes.

[0034] In another embodiment of this utility model, the charging and discharging assembly 7 includes a first cathode terminal, a second cathode terminal 72, and an anode terminal 73. Two first cathode terminals are provided, each fixedly connected to a first adjusting plate 53; two second cathode terminals 72 are provided, each fixedly connected to a second adjusting plate 63; and two anode terminals 73 are provided, each fixedly connected to a fixed plate 4. The first cathode terminal and the second cathode terminal 72 are adjusted by sliding the first adjusting plate 53 and the second adjusting plate 63 respectively, adapting to the cathode positions of different sizes of the lithium battery and ensuring stable contact with the negative electrode of the lithium battery. The anode terminal 73 is fixed to the fixed plate 4 and connected to the positive electrode of the lithium battery, forming a complete charging and discharging circuit in conjunction with the movable cathode terminals.

[0035] In another embodiment of this utility model, two slide rails 3 are provided, which are parallel and spaced apart, and both are fixedly connected to the tray body 1. The parallel and spaced arrangement of the two slide rails disperses the force on the first adjusting component 5 and the second adjusting component 6 through two-point support, preventing the first adjusting plate 53 and the second adjusting plate 63 from tilting or shaking, and enhancing the overall structural rigidity.

[0036] In another embodiment of this utility model, a plurality of heat dissipation holes 11 are provided at the bottom of the tray body 1, and are evenly distributed on the tray body 1. During the charging and discharging process of the lithium battery, heat is generated. The multiple evenly distributed heat dissipation holes 11 can form an air circulation channel, accelerate the air exchange between the tray body 1 and the outside, and dissipate the heat released by the lithium battery in a timely manner, so as to avoid heat accumulation in the tray.

[0037] In another embodiment of this utility model, a plurality of positioning holes 12 are provided on the side of the tray body 1, and are evenly distributed on the tray body 1. When the tray is placed on a charging and discharging device or related tooling rack, the positioning holes 12 can cooperate with positioning pins and other components on the device to quickly determine the installation position of the tray.

[0038] The adjustable charge / discharge tray for lithium batteries provided in this application operates as follows:

[0039] First, adjust the positions of the first adjusting component 5 and the second adjusting component 6 according to the size of the lithium battery to be charged and discharged. Specifically, loosen the first pin 54 and the second pin 64 to allow the first adjusting plate 53 and the second adjusting plate 63 to slide along the slide rail 3. Move the first adjusting plate 53 and the second adjusting plate 63 according to the length of the lithium battery so that the distance between them matches the length of the lithium battery; adjust the positions of the first adjusting component 5 and the second adjusting component 6 on the slide rail 3 according to the width of the lithium battery. After adjustment, insert the first pin 54 and the second pin 64 to fix the first adjusting plate 53 and the second adjusting plate 63 to the fixed beam 2.

[0040] Place the lithium battery on the tray body 1, so that the anode of the lithium battery contacts the anode terminal 73 on the fixing plate 4, and the cathode of the lithium battery contacts the first cathode terminal on the first adjusting plate 53 or the second cathode terminal 72 on the second adjusting plate 63. Then the charging and discharging operation can be performed.

[0041] During charging and discharging, the first and second elastic elements act as buffers, reducing the impact of vibrations generated during charging and discharging on the lithium battery. Simultaneously, the heat dissipation holes 11 at the bottom of the tray body 1 help dissipate heat from the lithium battery, improving its lifespan and safety.

[0042] The adjustable charging and discharging tray for lithium batteries provided in this application can be flexibly adjusted according to the actual size of the lithium battery through the setting of the first adjustment component 5 and the second adjustment component 6, thereby adapting to lithium batteries of different sizes. There is no need to equip a separate tray for each size of lithium battery, which improves the versatility and ease of use of the tray.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
