Description

Technical Field

[0001] The utility model relates to the technical field of positioning pins, in particular to a positioning pin with a clamping structure for a lithium battery pack. Background Technique

[0002] A lithium battery is a primary battery and a rechargeable lithium-ion battery using a non-aqueous electrolyte solution with lithium metal or lithium alloy as the negative electrode material, which is different from a lithium-ion polymer battery. The inventor of the lithium battery is Edison. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high requirements for the environment. Therefore, lithium batteries have not been applied for a long time. With the development of microelectronics technology at the end of the 20th century, the number of miniaturized devices has increased day by day, putting forward high requirements for power sources. Lithium batteries have thus entered the large-scale practical stage. During the production process of lithium batteries, it is necessary to clamp the lithium batteries.

[0003] When the existing positioning pins are installed and used, the structure is simple, and they can only fixedly clamp a single model of lithium battery pack, which is not convenient for workers to clamp and fix lithium battery packs of different specifications. At the same time, it is impossible to dissipate heat from the lithium battery pack in the working state in a timely manner, which brings certain adverse effects to the use process of people. In order to solve the deficiencies of the existing technology, we propose a positioning pin with a clamping structure for a lithium battery pack. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a positioning pin with a clamping structure for a lithium battery pack, which can effectively solve the problems in the background technique.

A fixing screw is arranged between the heat dissipation fan and the base. A square hole is arranged on the inner wall above the base. A top cover is arranged above the base. A clamping groove is arranged on the inner wall above the base. A fixing clamping block is arranged below the top cover. The fixing clamping block is inside the clamping groove. A convex block is arranged below the fixing clamping block. The number of the convex blocks is four groups. A handle is arranged on the upper surface of the top cover.

[0012] Beneficial effects

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] 1. In the present utility model, the storage battery is placed inside the base. The fixed side plate is pushed by the provided spring and expansion rod to fix the periphery of the storage battery. After the storage battery is placed, the staff covers the top cover, and the fixing block below the top cover is stuck inside the slot, and at the same time, the convex block below the fixing block is stuck inside the square hole. The provided convex block and square hole facilitate the staff to install and disassemble the top cover and the base. At the same time, the provided fixing block and slot limit the top cover and the base to prevent them from shifting during the installation process.

[0015] 2. In the present utility model, when the staff fixes the top cover above the base, it will drive the spring and the telescopic rod to expand and contract, and at the same time control the pressing plate to contact the upper surface of the storage battery, so as to fix the storage battery in the up and down direction and prevent it from sliding inside the base. The through holes provided facilitate the staff to pass the positive and negative electrodes above the storage battery through the middle of the through holes, so that they are exposed above the top cover, which is convenient for the staff to connect them. The handle provided facilitates the staff to carry the fixed storage battery. The connecting block provided facilitates the staff to fix the storage battery. When the staff fixes the storage battery, the cooling fan is started while the storage battery is operating.

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.

[0022] Such as Figure 1 - Figure 2As shown in the figure, a positioning pin with a clamping structure for a lithium battery pack includes a base 1. Inside the base 1, there are multiple groups of fixed side plates 14. The storage battery 12 is placed inside the fixed side plates 14, and the multiple groups of fixed side plates 14 are used to fix the storage battery 12. After the staff fixes the storage battery 12, the top cover 7 is placed above the base 1. The fixed clamping block 10 below the top cover 7 is stuck inside the card slot 13, and at the same time, the convex block 11 is inside the square hole 6. The convex block 11 and the square hole 6 are provided to facilitate the connection between the top cover 7 and the base 1 by the staff, which is convenient for the staff to install and disassemble it, and is convenient for the staff to repair and replace the storage battery 12 later. At the same time, the connection blocks 2 provided on both sides of the base 1 facilitate the staff to fix the base 1. When the storage battery 12 starts to operate, the cooling fan 4 is started. The heat generated by the storage battery 12 is released to the outside through the cooling fan 4 provided. The multiple air inlets 3 provided accelerate the flow rate of air entering the inside of the base 1, thereby improving the heat dissipation effect of the cooling fan 4. The fixing screws 5 provided facilitate the staff to install and disassemble the cooling fan 4.

[0023] As Figure 3 - Figure 4 As shown in the figure, for a positioning pin with a clamping structure for a lithium battery pack, when the staff places the storage battery 12 inside the base 1, the storage battery 12 will squeeze the fixed side plates 14, thereby squeezing the springs 15 and the telescopic rods 16. The springs 15 and the telescopic rods 16 provided push the fixed side plates 14 to make them close to the side of the storage battery 12, fixing the outside of the storage battery 12. Through holes are provided inside the fixed side plates 14 to reduce the contact area between the fixed side plates 14 and the storage battery 12, increase the air flow speed, and prevent the heat generated when the storage battery 12 works from not being dissipated in time, affecting the battery life. When the staff fixes the top cover 7 above the base 1, the pressure plate 17 is simultaneously pressed against the upper surface of the storage battery 12. When the staff presses down the top cover 7, the springs 15 and the telescopic rods 16 will be squeezed. When the staff sticks the convex block 11 inside the square hole 6, the staff stops squeezing the top cover 7. Under the action of the springs 15 and the telescopic rods 16, the top cover 7 will be bounced upward, making the convex block 11 in close contact with the square hole 6, thereby fixing the top cover 7 and the base 1. The fixed clamping block 10 and the card slot 13 provided facilitate the staff to align the top cover 7 and the base 1, preventing the top cover 7 and the base 1 from shifting. The handle 8 provided facilitates the staff to carry the fixed storage battery 12, greatly reducing the labor intensity of the staff, facilitating the operation of the workers, improving the practicability of the equipment, reducing the input cost, and enhancing the market competition advantage.
