Description

Technical Field

[0001] This utility model belongs to the field of lithium battery technology, and in particular relates to a portable lithium battery. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Lithium-ion batteries have advantages such as large capacity, high operating voltage, and strong charge retention, and are therefore widely used in various fields. However, current lithium-ion batteries lack portability, making them inconvenient for users to carry for outdoor use.

[0003] For example, patent application number 202222645591.0 describes a portable lithium battery, comprising a casing, a mounting bracket, a rotating plate, a lithium battery body, a cover plate, screws, and chucks. The mounting bracket is fixed to both the left and right sides of the front of the casing. The lithium battery body is located inside the casing. The rotating plate is rotatably mounted on the mounting bracket, and the cover plate is rotatably mounted on the lower rear of the casing. Screws are threaded onto the rotating plate and threadedly connected to the cover plate. Chucks are fixed to both the left and right sides of the casing. By loosening the connecting rod, the elastic element resets, causing the sliding rod and connecting rod to move inward. The inward movement of the sliding rod engages with the chucks, thereby limiting the handle and preventing it from rotating arbitrarily.

[0004] The above structure can solve the problem of lithium batteries being inconvenient to carry, but the above structure still has the following drawbacks:

[0005] 1. Existing technology opens the outer casing by rotating the cover and then directly inserts the lithium battery into the casing. However, the above structure lacks the function of limiting the lithium battery, which makes the lithium battery easy to shake inside the casing when carrying it out. This causes friction or even collision between lithium batteries and between the lithium battery and the casing, which can lead to damage to the lithium battery.

[0006] 2. Existing heat dissipation structures are fixed in location and can only provide concentrated heat dissipation for a portion of the lithium battery. Ineffective heat dissipation is not possible on the contact surface between the lithium battery and external objects, or in the area between two adjacent lithium batteries, resulting in poor heat dissipation performance of the lithium battery. Utility Model Content

[0007] To overcome the shortcomings of the prior art, this utility model provides a portable lithium battery. This utility model uses multiple clamping plates and limiting rods to clamp and limit the lithium battery at four positions (front, back, left, and right) to prevent the lithium battery from shaking or being bumped inside the box. In addition, with the first cavity, second cavity, multiple first exhaust holes and multiple second exhaust holes, air is blown to various positions inside the box to dissipate heat from various parts of the lithium battery, resulting in good heat dissipation effect.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a portable lithium battery, comprising a housing, a partition plate disposed inside the housing, multiple pairs of clamping plates slidably disposed on both sides of the partition plate within the housing, multiple first sliding grooves disposed at the bottom of the housing, the lower ends of the clamping plates slidably disposed within the first sliding grooves, a guide plate disposed at the upper end of each clamping plate, each guide plate being inclined, a first cavity disposed on the inner wall of the housing, a second cavity disposed within the partition plate, the first cavity and the second cavity being interconnected, an air inlet pipe disposed on one side of the housing, the air inlet pipe being interconnected with the first cavity, and an exhaust port disposed on the other side of the housing.

[0009] Preferably, the upper end of the box is hinged with an end cap, and the upper surface of the end cap is provided with a carrying handle.

[0010] Preferably, multiple first exhaust holes are provided on both ends of the partition plate.

[0011] Preferably, a plurality of second exhaust holes are provided on one side of the first cavity on the inner wall of the box.

[0012] Preferably, a first spring is provided on one side of the clamping plate between the housing and the box body.

[0013] Preferably, the clamping plate is provided with multiple ventilation holes.

[0014] Preferably, two second sliding grooves are provided on one end face of the clamping plate, and a limit rod is slidably provided in each second sliding groove. The upper end face of the limit rod is provided with an arc surface, and a cooling cavity is provided in the limit rod. The cooling cavity is filled with refrigerant. A second spring is provided on both sides of the limit rod in the second sliding groove, and the other end of the second spring is connected to the clamping plate.

[0015] Preferably, a bracket is provided below the air inlet pipe outside the housing, a motor is provided on the bracket, and multiple fan blades are connected to the output end of the motor.

[0016] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0017] (1) This utility model uses multiple clamping plates, a first spring, multiple limiting rods and a second spring to clamp and limit the lithium battery in four positions: front, back, left and right, to prevent the lithium battery from shaking or being bumped in the box. It also has the function of self-adapting to lithium batteries of different sizes, and is highly practical.

[0018] (2) This utility model uses an air inlet pipe, a first cavity, a second cavity, multiple first exhaust holes, multiple second exhaust holes and multiple ventilation holes to allow air to be blown to various positions inside the box, which can dissipate heat to various positions of the lithium battery, resulting in good heat dissipation effect of the lithium battery. Furthermore, the lithium battery can be dissipated again through the refrigerant, which effectively improves the heat dissipation efficiency of the lithium battery. Attached Figure Description

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] refer to Figures 1-8As shown, a portable lithium battery includes a housing 1, a partition plate 2 inside the housing 1, and multiple pairs of clamping plates 3 slidably disposed on both sides of the partition plate 2 inside the housing 1. Multiple first sliding grooves 21 are provided at the bottom of the housing 1, and the lower ends of the clamping plates 3 are slidably disposed in the first sliding grooves 21. Each clamping plate 3 has a guide plate 4 at its upper end, and each guide plate 4 is inclined. A first cavity 5 is provided on the inner wall of the housing 1, and a second cavity 6 is provided inside the partition plate 2. The first cavity 5 and the second cavity 6 are interconnected. An air inlet pipe 20 is provided on one side of the housing 1, and the air inlet pipe 20 is interconnected with the first cavity 5. An exhaust port 16 is provided on the other side of the housing 1.

[0030] In use, open the housing 1, place the lithium battery between the two support plates 3, and press the lithium battery down. At this time, the lithium battery, through the setting of the guide plate 4, causes the two clamping plates 3 to slide in the opposite direction through the first sliding groove 21 as the lithium battery moves downward, until the lower section of the lithium battery contacts the bottom of the housing 1. At this time, the two clamping plates 3 achieve clamping and limiting of the lithium battery. Since the clamping plates 3 can slide freely, they can adapt to lithium batteries of different sizes. The operation is simple and practical. Since the clamping plates 3 are set on both sides of the partition plate 2 and there are multiple clamping plates, multiple lithium batteries can be stored and managed, making it convenient to carry a large number of lithium batteries. Through the air inlet pipe 20, the first cavity 5 and the second cavity 6, the air can enter various positions in the housing 1, so that the lithium battery and the housing and the lithium batteries can also be ventilated, thus making the heat dissipation of the lithium battery in the housing 1 good. Finally, the air in the housing 1 can be discharged through the exhaust port 16.

[0031] For details, please refer to Figure 1 As shown, an end cover 7 is hinged to the upper end of the box 1, and a carrying plate 8 is provided on the upper surface of the end cover 7.

[0032] The end cap, which is hinged to the box body 1, can be opened or closed. When opened, it is convenient to place the lithium battery, and when closed, the carrying handle 8 makes the box body 1 easy to carry, thus making the lithium battery easy to carry.

[0033] For details, please refer to Figure 4 As shown, multiple first exhaust holes 9 are provided on both ends of the partition plate 2.

[0034] Air enters through the air inlet pipe 20, then enters the second cavity 6, and is discharged through multiple first exhaust holes 9, so that air is exhausted into the box 1 from both sides of the partition plate 2, thereby effectively dissipating heat from the lithium battery inside the box 1.

[0035] For details, please refer to Figure 4 As shown, a plurality of second exhaust holes 10 are provided on one side of the first cavity 5 on the inner wall of the box 1.

[0036] The air inside the first cavity 5 is discharged through multiple second exhaust holes 10, and together with the multiple first exhaust holes 9, the air on both sides of the lithium battery comes into contact with the air, which effectively increases the flow coverage area outside the lithium battery and ensures the heat dissipation quality.

[0037] For details, please refer to Figure 3 As shown, a first spring 11 is provided on one side of the clamping plate 3 between the box body 1.

[0038] When the two clamping plates 3 move in opposite directions on the first slide groove 21, the first spring 11 is compressed. The spring 11 itself limits the lithium battery on both sides, preventing the lithium battery from shaking or bumping inside the housing 1.

[0039] For details, please refer to Figure 3 As shown, the clamping plate 3 is provided with multiple ventilation holes 12.

[0040] The air inside the housing 1 can pass through multiple ventilation holes 12, so that the clamping surface between the clamping plate 2 and the lithium battery, as well as the contact surface between the lithium batteries, can be effectively cooled, thus improving the heat dissipation quality.

[0041] For details, please refer to Figure 3 , Figure 5 , Figure 6 As shown, two second sliding grooves 22 are provided on one side end face of the clamping plate 3. A limit rod 13 is slidably provided in each second sliding groove 22. An arc surface 23 is provided on the upper end face of the limit rod 13. A cooling chamber 14 is provided in the limit rod 13. The cooling chamber 14 is filled with refrigerant. A second spring 15 is provided on both sides of the limit rod 13 in the second sliding groove 22. The other end of the second spring 15 is connected to the clamping plate 3.

[0042] When the lithium battery is placed into the housing 1, the guide plate 4 causes the two clamping plates 2 to move in opposite directions. At the same time, the upper arc surface 23 of the limiting rod 12 causes the two limiting rods to move in opposite directions. Simultaneously, multiple springs 15 extend and retract. After the lower section of the lithium battery contacts the bottom of the housing 1, it indicates that the lithium battery has been placed. At this time, the two clamping plates 3 and the four limiting rods 13 limit the lithium battery at four positions, which has a good limiting effect and prevents the lithium battery from shaking or being bumped in the housing 1. Since the cooling chamber 14 inside the limiting rod 13 is filled with refrigerant, the refrigerant can dissipate heat from the lithium battery again, resulting in good heat dissipation effect and high heat dissipation efficiency. The refrigerant in this solution is existing technology and will not be elaborated on further.

[0043] For details, please refer to Figure 7 , Figure 8 As shown, a bracket 17 is installed below the air inlet pipe 20 outside the housing 1. A motor 18 is installed on the bracket 17, and multiple fan blades 19 are connected to the output end of the motor 18.

[0044] When the motor 18 is started, it drives multiple fan blades 19 to rotate. The air generated by the rotation of the multiple fan blades 20 enters the housing 1 through the air inlet pipe 20 to dissipate heat from the lithium battery inside the housing 1. The motor 18 and the multiple fan blades 19 are existing technologies and can be modified according to actual needs. This solution does not impose too many restrictions.
