Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery technology, specifically to a lithium-ion battery with a protective structure. Background Technology

[0002] A lithium-ion battery is a type of rechargeable battery that primarily relies on the movement of lithium ions between the positive and negative electrodes to function. During charging and discharging, Li+ ions move back and forth between the two electrodes, inserting and deintercalating. When charging, Li+ ions are deintercalated from the positive electrode and inserted into the negative electrode via the electrolyte, leaving the negative electrode in a lithium-rich state. The opposite occurs during discharging. Lithium-based batteries are divided into lithium batteries and lithium-ion batteries. Mobile phones and laptops use lithium-ion batteries, which are commonly referred to as lithium batteries.

[0003] Some existing lithium-ion batteries lack protective structures. During use, they are easily damaged by impacts from external objects when the carrier collides with the battery, which can even cause fires in severe cases. To address these issues, the inventors propose a lithium-ion battery with a protective structure. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-5 As shown, this utility model provides a lithium-ion battery with a protective structure, including a lithium-ion battery body 1 and a protective shell 2. The lithium-ion battery body 1 is installed inside the protective shell 2. The protective shell 2 includes an upper shell 21 and a lower shell 22. One end of the upper shell 21 is hinged to one end of the lower shell 22. Anti-collision strips 4 are fixedly installed on the four sides of the upper surface of the upper shell 21 and the four sides of the lower surface of the lower shell 22. Both ends of the protective shell 2 have reserved openings 3. Two mirror-distributed limiting components 7 are installed on one end of the protective shell 2, which can hold the lithium-ion battery body. 1. Installed inside the protective shell 2, the protective shell 2 can protect the lithium-ion battery body 1 and prevent external objects from directly impacting the lithium-ion battery body 1. It can prevent the lithium-ion battery body 1 from being damaged by abnormal conditions such as dents, cracks or deformation due to impact or friction. The anti-collision strip 4 can buffer and unload the force when external objects hit the protective shell 2, reducing a certain impact force. The reserved openings 3 at both ends of the protective shell 2 facilitate the connection of the positive and negative terminals at both ends of the lithium-ion battery body 1. The limiting component 7 can control the opening and closing of the protective shell 2, which is convenient for the installation and removal of the lithium-ion battery body 1.

[0021] Both limiting components 7 include a sliding plate 72, and a lever 71 is fixedly installed on one side of each sliding plate 72. Limiting blocks 73 are fixedly installed on the top sides of the two sliding plates 72 that are close to each other.

[0022] By adopting the above technical solution, the sliding plate 72 and the limiting block 73 are driven to slide by the pusher block 71.

[0023] Two symmetrically distributed first sliding grooves 8 are provided at one end of the lower housing 22, and the sliding plate 72 is slidably installed in the corresponding first sliding groove 8.

[0024] By adopting the above technical solution, the sliding plate 72 and the limiting block 73 are driven by the pusher block 71 to slide in the corresponding first slide groove 8.

[0025] A fixing rod 74 is fixedly installed in each of the two first sliding grooves 8, and the fixing rod 74 is inserted through the corresponding sliding plate 72. A spring 75 is sleeved on each of the two fixing rods 74.

[0026] By adopting the above technical solution, the sliding plate 72 and the limiting block 73 are driven by the toggle block 71 to slide along the fixed rod 74 in the corresponding first slide groove 8, and the sliding plate 72 can be reset by the rebound force of the spring 75.

[0027] Two symmetrically distributed second sliding grooves 9 are provided at one end of the upper housing 21, and the sliding plate 72 can slide in the corresponding second sliding groove 9.

[0028] By adopting the above technical solution, the sliding plate 72 can slide within the corresponding second sliding groove 9.

[0029] Each of the two second slide grooves 9 has a limiting groove 76, and the limiting block 73 can be inserted into the corresponding limiting groove 76.

[0030] By adopting the above technical solution, after the protective shell 2 is closed, the sliding plate 72 drives the limiting block 73 to insert into the corresponding limiting groove 76, thereby limiting the upper shell 21.

[0031] Heat dissipation holes 5 are provided on the upper surface and both sides of the upper housing 21 and on the lower surface and both sides of the lower housing 22.

[0032] By adopting the above technical solution, the lithium-ion battery body 1 can dissipate heat and ventilate through the heat dissipation holes 5.

[0033] Both the upper housing 21 and the lower housing 22 have pads 6 fixedly installed inside them.

[0034] By adopting the above technical solution, the pad 6 is made of rubber, which can prevent the protective shell 2 from damaging the lithium-ion battery body 1, and can also provide further protection for the lithium-ion battery body 1 in the event of an impact.

[0035] Working principle: In use, the lever 71 is first manually moved. The lever 71 drives the sliding plate 72 and the limiting block 73 to slide along the fixed rod 74 within the corresponding first sliding groove 8, and compresses the spring 75, causing the limiting block 73 to disengage from the limiting groove 76. Then, the upper housing 21 is opened, the lithium-ion battery body 1 is placed into the lower housing 22, and the upper housing 21 is closed. Then, the lever 71 is released, and the spring 75's rebound force causes the sliding plate 72 to drive the limiting block 73 into the corresponding limiting groove 76, thus aligning the upper and lower housings. The casing 21 provides a limit, and the protective casing 2 can protect the lithium-ion battery body 1, preventing external objects from directly impacting the lithium-ion battery body 1 and avoiding damage to the battery caused by abnormal conditions such as dents, cracks or deformations due to impact or friction. The anti-collision strip 4 can buffer and unload force when external objects impact the protective casing 2, reducing a certain impact force. The reserved openings 3 at both ends of the protective casing 2 facilitate the connection of the positive and negative terminals at both ends of the lithium-ion battery body 1. The lithium-ion battery body 1 can dissipate heat and ventilate through the heat dissipation holes 5.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
