Description

Technical Field

[0001] This utility model belongs to the field of battery electrode protection technology, specifically relating to a protective structure for the positive and negative terminals of a new energy battery. Background Technology

[0002] New energy batteries are a new type of energy storage device that can convert various forms of energy into chemical energy for storage and release it for people to use when needed. The basic components of a new energy battery include positive electrode materials, negative electrode materials, electrolytes, and separators. The selection of these materials has a significant impact on the battery's performance. The positive and negative electrodes inside a new energy battery need to be protected during use to avoid direct contact with external corrosive substances and excessively high temperatures, which could lead to short circuits, affect the normal use of the new energy battery, and even affect its lifespan. Therefore, protecting the positive and negative electrodes of a new energy battery is of great importance.

[0003] Chinese patent CN221239766U discloses a protective structure for the positive and negative terminals of a lithium-ion battery pack. This falls under the technical field of battery pack cover technology. It primarily addresses the problems of existing terminal protection structures, such as numerous component types, complex installation steps, low installation efficiency, and long product development cycles. Its main features are: a cover and terminals; a protective cap connected to the cover that can seal at least one side of the exposed portion of the terminals; and the protective cap being made of insulating material. This invention features protection of the battery's positive and negative terminals, effective sealing of the cover, reduced component types, lower product development cycle and cost, and improved assembly efficiency. It is mainly used for terminal protection of lithium-ion power batteries.

[0004] However, while the above-mentioned technical solution can achieve the purpose of protecting the lithium-ion battery terminals, the lack of a corresponding limiting structure after the protective cover protects the terminals means that if the lithium-ion battery is placed in a car and moves with the vehicle, the protective cover will move up and down with the vehicle. This up-and-down movement will cause the terminals to be exposed at times, making them susceptible to contact with excessively high temperatures, impurities, or dust inside the car. This can lead to poor contact during use, affecting the normal operation of the vehicle, and thus has certain limitations in its use. Utility Model Content

[0005] The purpose of this invention is to provide a protective structure for the positive and negative terminals of a new energy battery, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A protective structure for the positive and negative terminals of a new energy battery includes: a battery body, a sliding groove on one side of the top of the battery body, terminals inside the battery body, two sliding blocks slidably connected inside the sliding groove, a first movable clamp fixedly connected to the top of the sliding block, a movable rod hinged to the surface of the first movable clamp, a protective cover connected to the top of the battery body, a horizontal plate fixedly connected to the top of the surface of the protective cover, second movable clamps fixedly connected to both sides of the horizontal plate, and the end of the movable rod away from the first movable clamp hinged to the surface of the second movable clamp, a positioning rod fixedly and penetrating inside the sliding groove, a compression spring sleeved on the surface of the positioning rod, and the two ends of the compression spring fixedly connected to the opposite sides of the two sliding blocks respectively.

[0008] Preferably, a fixing plate is fixedly connected to one side of the first movable clamp surface, and a lead screw is threadedly connected to the inside of the fixing plate.

[0009] Preferably, a circular groove is formed on one side of the top of the battery body, and the terminal post is located inside the circular groove, and an annular groove is formed on the inner bottom wall of the circular groove.

[0010] Preferably, two L-shaped rods are fixedly connected to the bottom end of the inner sidewall of the protective cover, and a sealing ring is fixedly connected to the bottom end of the L-shaped rods. A first sealing strip is provided at the bottom of the sealing ring.

[0011] Preferably, an abutment block is fixedly connected to the bottom of the protective cover, and a second sealing strip is provided at the bottom of the abutment block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The terminals set inside the new energy battery can play a protective role. When the protective cover is placed on the surface of the terminal, it can prevent the protective cover from loosening through the resistance of the compression spring, thus ensuring the safety performance of the battery, extending the battery's service life, reducing the battery's failure rate, and improving the battery's efficiency. This not only helps to improve the overall performance of the battery, but also provides users with a safer, more reliable, and more efficient battery experience.

[0014] (2) When the two sliding blocks move to opposite positions to lift the protective cover, the staff can screw the screw into the two fixed blocks to lift the protective cover. This eliminates the need for the staff to hold the sliding blocks with their hands for a long time, reducing the labor intensity of the staff. At the same time, when the protective cover descends, it plays a double sealing role through the two sealing rings. Attached Figure Description

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.

[0021] Example 1:

[0022] Please see Figure 1 , Figure 2 and Figure 4As shown, a protective structure for the positive and negative terminals of a new energy battery includes a battery body 1. A sliding groove 2 is provided on one side of the top of the battery body 1. A terminal 3 is provided inside the battery body 1. Two sliding blocks 4 are slidably connected inside the sliding groove 2. A first movable clamp 5 is fixedly connected to the top of the sliding block 4. A movable rod 6 is hinged to the surface of the first movable clamp 5. A protective cover 7 is connected to the top of the battery body 1. A horizontal plate 8 is fixedly connected to the top of the surface of the protective cover 7. A second movable clamp 9 is fixedly connected to both sides of the horizontal plate 8. The end of the movable rod 6 away from the first movable clamp 5 is hinged to the surface of the second movable clamp 9. A positioning rod 10 is fixedly and penetrates inside the sliding groove 2. A compression spring 11 is sleeved on the surface of the positioning rod 10. The two ends of the compression spring 11 are fixedly connected to the opposite sides of the two sliding blocks 4, respectively. The sliding groove 2 allows the sliding block 4 to slide inside it. The first movable clamp 5 allows the movable rod 6 to be hinged to its surface. The movable rod 6 allows the cross plate 8 to be lifted to a certain height by the second movable clamp 9 and the movable rod 6. The positioning rod 10 provides a guiding function for the sliding block 4 during movement. The surface of the positioning rod 10 penetrates the interior of the two sliding blocks 4. The compression spring 11 causes the two sliding blocks 4 to come close to each other and be squeezed. When the two sliding blocks 4 need to be separated, they can automatically reset. The protective cover 7 is made of insulating material.

[0023] Example 2:

[0024] Please see Figures 1 to 3 As shown, a fixing plate 12 is fixedly connected to one side of the surface of the first movable clamp 5, and a screw rod 13 is threadedly connected to the inside of the fixing plate 12. The screw rod 13 allows it to be screwed into the inside of the fixing plate 12. It should be noted that the front sides of both first movable clamps 5 are fixedly connected to the fixing plate 12. After the two first movable clamps 5 are brought close together, the operator can screw the screw rod 13 into the inside of the fixing plate 12 inside the left first movable clamp 5. At this time, the two first movable clamps 5 are fixed together, and the compression spring 11 is in a compressed state.

[0025] A circular groove 14 is provided on one side of the top of the battery body 1, and the terminal post 3 is located inside the circular groove 14. An annular groove 15 is provided on the inner bottom wall of the circular groove 14.

[0026] Two L-shaped rods 16 are fixedly connected to the bottom of the inner wall of the protective cover 7. A sealing ring 19 is fixedly connected to the bottom of the L-shaped rod 16, and a first sealing strip 20 is provided at the bottom of the sealing ring 19. By opening the annular groove 15, the sealing ring 19 can drive the first sealing strip 20 to abut against its inner wall, further ensuring the safety of the pole post 3.

[0027] A contact block 17 is fixedly connected to the bottom of the protective cover 7, and a second sealing strip 18 is provided at the bottom of the contact block 17. The contact block 17 and the second sealing strip 18 ensure the sealing of the protective cover 7 after it is pressed down and connected to the battery body 1, thus preventing the terminal post 3 from contacting the outside.

[0028] The working principle of this utility model is as follows: The operator pushes the two sliding blocks 4 to opposite positions. Then, the two ends of the movable rod 6 are hinged to the surfaces of the first movable clamp 5 and the second movable clamp 9, which lifts the horizontal plate 8 to a certain height. During this process, the two sliding blocks 4 move towards each other through the positioning rod 10, and the compression spring 11 is squeezed and compressed. After the two sliding blocks 4 move to a position close to each other, the operator screws the screw rod 13 into the fixed plate 12 on the left side. At this time, the two sliding blocks 4 are fixed, and the protective cover 7 is lifted to a certain height. Then, the pole post 3 is directly exposed. To protect it, the operator simply reverses the operation so that the protective cover 7 fits onto the surface of the pole post 3. At the same time, the sealing ring 19 drives the first sealing strip 20 to abut against the inside of the annular groove 15, and the abutting block 17 drives the second sealing strip 18 to abut against the top of the battery body 1, which achieves a double sealing effect on the pole post 3.
