Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery casing technology, and in particular to a novel lithium battery casing. Background Technology
[0002] Lithium-ion batteries are a type of electrochemical battery that uses lithium metal or lithium ions as electrode materials. With advantages such as high energy density, long cycle life, and low self-discharge rate, they have become the core power source for modern electronic devices. Their working principle is based on the insertion and extraction of lithium ions between the positive and negative electrodes. During charging, lithium ions move from the positive electrode to the negative electrode, and during discharging, they move in the opposite direction, realizing the conversion of electrical energy into chemical energy. According to their structure, they can be divided into liquid lithium batteries and solid lithium batteries. They are widely used in mobile phones, electric vehicles, energy storage systems and other fields. However, attention should be paid to the risk of thermal runaway caused by overcharging and over-discharging, and they need to be used in conjunction with protection circuits.
[0003] In existing technologies, the internal lithium battery needs to be protected by an outer casing to prevent damage from collisions. Most existing lithium battery casings are rectangular, which is convenient for transportation and placement. However, in actual use, lithium batteries need to be stacked during bulk transportation. Since there is no connection between existing lithium battery casings, they are prone to tipping over or misalignment once shaken after stacking, which has certain shortcomings. In view of this, we propose a new type of lithium battery casing. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0024] Please see Figure 1-5 This utility model provides a technical solution: a novel lithium battery casing, including a lithium battery casing 1. Two mounting plates 2 are fixedly connected to the left and right sides of the lithium battery casing 1, and a connecting shaft 3 is fixedly connected between the two mounting plates 2. A handle 4 is rotatably sleeved on the outer surface of the connecting shaft 3. Limiting baffles 5 are fixedly connected to the upper surfaces of the two mounting plates 2. A docking groove 6 is opened on the upper surface of the lithium battery casing 1. Slots 7 are opened on the inner walls of the left and right sides of the docking groove 6. The two slots 7 are staggered. A docking plate 8 is fixedly connected to the lower surface of the lithium battery casing 1. Blocks 9 are provided on the left and right sides of the docking plate 8. The lower surface of the blocks 9 is inclined. The blocks 9 are adapted to the slots 7. The docking plate 8 is adapted to the docking groove 6. A docking component is provided on the handle 4. When multiple lithium battery casings 1 are stacked, docking can be completed through the cooperation of the docking plate 8, docking groove 6, slots 7 and blocks 9. This ensures safety during transportation, preventing misalignment between lithium battery casings 1 due to shaking.
[0025] Furthermore, the docking assembly includes a connecting rod 10, which is rotatably connected to the lower surface of the handle 4. Extension slots 11 are respectively formed on the left and right surfaces of the lithium battery casing 1. A motion cavity 12 is formed inside the lithium battery casing 1, communicating with the extension slots 11. A U-shaped motion plate 13 is slidably connected inside the motion cavity 12. The two horizontal plates of the U-shaped motion plate 13 extend outwards from the lithium battery casing 1 through the two extension slots 11. A connecting frame 14 is fixedly connected to the ends of the two horizontal plates of the U-shaped motion plate 13. The end of the connecting rod 10 is rotatably connected to the connecting frame 14. The surfaces of the two adjacent left and right locking blocks 9 slide through the interior of the docking plate 8. A spring 15 is fixedly connected between the locking blocks 9 and the inner wall of the docking plate 8. Two fixing plates 16 are fixedly connected to the inner wall of the 8, and a roller 17 is rotatably connected between the two fixing plates 16. A connecting rope 18 is fixedly connected to the lower surface of the U-shaped moving plate 13. The connecting rope 18 is fixedly connected to the locking block 9 after passing through the roller 17. A support column 19 is fixedly connected to the lower surface of the lithium battery shell 1. A heat dissipation fin 20 is fixedly connected to the lower surface of the lithium battery shell 1. A clearance groove 21 adapted to the support column 19 and the heat dissipation fin 20 is opened on the upper surface of the lithium battery shell 1. When unlocking multiple lithium battery shells 1, the whole operation does not require any extra steps. Just hold the handle 4 and pull it up. It is intuitive to operate. Moreover, the heat dissipation fin 20 can effectively assist in heat dissipation and ensure the safety of the lithium battery during operation.
[0026] The connecting rope 18 has a certain degree of elasticity, which allows the locking block 9 to be pulled into the docking plate 8 when the handle 4 is in a horizontal state without breaking the connecting rope 18. At the same time, the length of the support column 19 is greater than that of the heat dissipation fins 20 and the docking plate 8, preventing the heat dissipation fins 20 and the docking plate 8 from directly contacting the ground.
[0027] Working principle: When docking multiple sets of lithium battery casings 1 for transportation, one lithium battery casing 1 can be placed on top of another lithium battery casing 1, with the support column 19 inserted into the recess 21. Due to gravity, the handle 4 is in a drooping state. When the docking plate 8 enters the docking groove 6, the inner wall of the docking groove 6 presses against the locking block 9. The inclined shape of the lower surface of the locking block 9 forces it to retract into the docking plate 8. Simultaneously, the spring 15 is compressed as the locking block 9 moves. When the docking plate 8 continues to move, aligning the locking block 9 with the groove 7, the spring force of the spring 15 causes the locking block 9 to pop out again and re-enter the groove 7. At this point, the upper surface of the locking block 9 contacts the surface of the groove 7. To disconnect the two lithium battery casings 1, and then remove them, you can hold the two handles 4 with both hands and pull upwards. During the pull, the handles 4 will first rotate upwards to a horizontal position. At this time, the upper surface of the handles 4 will contact the limiting baffle 5. As the handles 4 rotate, they will simultaneously drive the connecting rod 10 to move. The connecting rod 10 will then drive the connecting frame 14 and the U-shaped moving plate 13 to move vertically. When the U-shaped moving plate 13 moves, it will simultaneously pull the locking block 9 with the connecting rope 18 and the roller 17. After the locking block 9 moves, it will retract back into the docking plate 8 to complete the unlocking. At this time, the lithium battery casing 1 can be removed. The entire operation requires no extra steps; simply hold the handles 4 and pull upwards. It is intuitive to operate.
[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
