Description

Technical Field

[0001] This utility model belongs to the field of battery component technology, and in particular relates to a long-life battery terminal sealing structure. Background Technology

[0002] A battery terminal sealing structure refers to a structural design used to seal the battery terminals. Its main purpose is to prevent electrolyte leakage and protect the terminals from external environmental corrosion. This sealing structure typically includes multiple components, such as sealing rings, gaskets, and sealant, which work together to ensure the battery's sealing and safety. However, it still has the following drawbacks in practical use:

[0003] When the battery terminals are sealed, they are directly installed in the appropriate position through the sealing structure. During the installation process, they can only be sealed with sealant to seal the gaps between the battery electrodes and the external power connection structure and the top cover. The stability of the seal is not long enough.

[0004] When the battery terminals are sealed by a sealing structure, they directly contact the battery electrodes through the internal sealing structure before being connected to the outside. During the connection process, factors such as deformation of the battery structure can easily cause poor contact between the terminals and the connection structure, affecting the connection effect. Utility Model Content

[0005] The purpose of this utility model is to provide a long-life battery terminal sealing structure. By setting a movable sleeve, a rotating block, a fixed plate and a spring-loaded component, it solves the problem that the sealing life of the battery terminal sealing structure is not long enough and that it is easy to cause poor contact between the terminal and the connection structure.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a long-life battery terminal sealing structure, comprising a movable sleeve, a rotating block, a fixed plate, and a spring-loaded assembly. An external threaded cylinder is fixed to the top of the movable sleeve, and an internal threaded cylinder is threadedly connected to the periphery of the external threaded cylinder. A rotating block is fixed to the top of the internal threaded cylinder, and a fixed plate is fixed to the center of the top of the rotating block. A spring-loaded assembly is fixed to the bottom of the rotating block outside the internal threaded cylinder, and a compression spring is fixed to the bottom of the rotating block. During operation, the external threaded cylinder is connected to the movable sleeve, the internal threaded cylinder is connected to the external threaded cylinder, and the rotating block is connected to the internal threaded cylinder. The spring-loaded assembly and the fixed plate are connected to the rotating block. The fixed plate is connected to an external power-connected structure. The spring-loaded assembly engages to press the fixed plate at the bottom of the movable sleeve against the top of the battery.

[0008] Furthermore, a fixed plate is fixed to the lower periphery of the movable sleeve. The inner diameter of the movable sleeve is equal to the inner diameter of the external threaded cylinder, and the outer diameter of the movable sleeve is larger than the outer diameter of the external threaded cylinder. When the movable sleeve is working, the sealing ring is connected to it through the fixed plate.

[0009] Furthermore, a flexible sealing ring is fixed to the top of the fixed plate. The flexible sealing ring is located on the outside of the movable sleeve to seal the space between the battery top cover and the movable sleeve.

[0010] Furthermore, the bottom end of the compression spring is fixed with an abutment block. The compression spring is disposed inside the movable sleeve and the external threaded cylinder, and the abutment block is disposed inside the movable sleeve, so that when working, the battery electrode post and the ear plate are stably connected.

[0011] Furthermore, two symmetrical ear plates are fixed to the top of the fixing plate, and each ear plate has a through-hole for mounting, so that it can be installed in conjunction with the external power connection structure during operation.

[0012] Furthermore, the rebound assembly includes a fixed ring and a second compression spring. The second compression spring is fixed to the bottom end of the fixed ring. The fixed ring is fixed to the bottom of the rotating block. Both the fixed ring and the second compression spring are located on the outside of the internal threaded cylinder, so that the movable sleeve and the rotating block are securely mounted on the battery top cover during operation.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of insufficient sealing life of the battery terminal sealing structure by setting up a movable sleeve, a rotating block, and a spring-loaded assembly. After the movable sleeve and the rotating block are installed on the battery top cover, the compression spring is compressed, providing an upward thrust to the rotating block, so that the flexible sealing ring on the fixed plate abuts against the inner top of the battery top cover, thus making the sealing life of the battery terminal sealing structure longer.

[0015] This invention solves the problem of poor contact between the battery terminal sealing structure and the power connection structure by setting up a movable sleeve, a rotating block, and a fixed plate. The movable sleeve is installed on the top cover of the battery. After the top cover of the battery is installed, the abutting block at the bottom of the compression spring abuts against the terminal inside the battery, so that the ear plate on the fixed plate is stably connected to the terminal inside the battery, and the battery terminal sealing structure and the battery terminal are well and stably connected.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0026] Please see Figure 1-5This utility model relates to a long-life battery terminal sealing structure, comprising a movable sleeve 1, a rotating block 2, a fixed plate 3, and a spring-loaded assembly 4. An externally threaded cylinder 103 is fixed to the top of the movable sleeve 1. During operation, the movable sleeve 1 is movably connected to the battery top cover and is threadedly connected to an internally threaded cylinder 201 via the externally threaded cylinder 103. The circumferential side of the externally threaded cylinder 103 is threaded with the internally threaded cylinder 201, which in turn is threaded onto the externally threaded cylinder 103. This allows the movable sleeve 1 to be mounted on the battery top cover. A rotating block 2 is fixed at the top of the cylinder 201. When the rotating block 2 rotates, it drives the internal thread cylinder 201 to rotate. A fixing plate 3 is fixed at the center of the top of the rotating block 2. The ear plate 301 is connected through the fixing plate 3. A spring-loaded assembly 4 is fixed at the bottom of the rotating block 2 on the outside of the internal thread cylinder 201. The spring-loaded assembly 4 increases the fixing plate 101 to abut against the inner top of the battery top cover. A compression spring 202 is fixed at the bottom of the rotating block 2. The compression spring 202 is pressed against the battery terminal by the abutment block 203 to connect to the power supply.

[0027] Specifically, a fixed plate 101 is fixed to the lower part of the periphery of the movable sleeve 1. The inner diameter of the movable sleeve 1 is equal to the inner diameter of the external threaded cylinder 103, and the outer diameter of the movable sleeve 1 is greater than the outer diameter of the external threaded cylinder 103. When the movable sleeve 1 is working, it is connected to the flexible sealing ring 102 through the fixed plate 101. Because the outer diameter of the movable sleeve 1 is greater than the outer diameter of the external threaded cylinder 103, when the internal threaded cylinder 201 is screwed to the periphery of the external threaded cylinder 103, the position is fixed by the movable sleeve 1.

[0028] Furthermore, a flexible sealing ring 102 is fixed to the top of the fixed plate 101. The flexible sealing ring 102 is located on the outside of the movable sleeve 1. When the fixed plate 101 is working, the flexible sealing ring 102 abuts against the inner top of the battery top cover to seal the gap between the movable sleeve 1 and the battery top cover.

[0029] Furthermore, the bottom end of the compression spring 202 is fixed with an abutment block 203. The compression spring 202 is set inside the movable sleeve 1 and the external threaded cylinder 103. The abutment block 203 is set inside the movable sleeve 1. When the rotating block 2 is installed on the outside of the external threaded cylinder 103, the bottom end of the abutment block 203 abuts against the top end of the battery terminal. The compression spring 202 makes the abutment block 203 abut against the battery terminal.

[0030] Furthermore, two symmetrical ear plates 301 are fixed on the top of the fixing plate 3. Each ear plate 301 has a through mounting hole 302. When the fixing plate 3 is working, the external power connection structure is first placed between the two ear plates 301 on the fixing plate 3, and then installed by mounting bolts and mounting nuts.

[0031] The operation process of this embodiment is as follows: During operation, the movable sleeve 1 is placed at the opening position corresponding to the battery terminal on the battery top cover. The movable sleeve 1 and the external threaded cylinder 103 are passed through the inside of the battery top cover. Then, the internal threaded cylinder 201 at the bottom of the rotating block 2 is aligned with the external threaded cylinder 103. The rotating block 2 is then rotated to drive the internal threaded cylinder 201 to rotate. Through the rotation of the internal threaded cylinder 201, the internal threaded cylinder 201 and the external threaded cylinder 103 are rotatably connected together. The movable sleeve 1 is installed on the battery top cover. After the battery top cover is installed, the abutment block 203 at the bottom of the compression spring 202 abuts against the terminal inside the battery, so that the ear plate 301 on the fixing plate 3 is stably connected to the terminal inside the battery. After the battery is assembled, the battery is connected to the outside by inserting the installation bolt into the mounting hole 302 and then installing it with the installation nut. Specific Implementation Example 2

[0032] Please see Figure 1-6 Based on the first specific embodiment, the rebound assembly 4 includes a fixing ring 401 and a compression spring 402. The bottom end of the fixing ring 401 is fixed with the compression spring 402. The fixing ring 401 is fixed to the bottom of the rotating block 2. Both the fixing ring 401 and the compression spring 402 are located on the outside of the internal threaded cylinder 201. When the rebound assembly 4 is working, it is connected to the rotating block 2 through the fixing ring 401 and abuts against the top of the battery top cover through the compression spring 402, so that the rotating block 2 is lifted upward when working.

[0033] The operation process of this embodiment is as follows: After the movable sleeve 1 and the rotating block 2 are installed on the battery top cover, the compression spring 402 is compressed, providing an upward thrust to the rotating block 2, so that the flexible sealing ring 102 on the fixed plate 101 abuts against the inner top of the battery top cover, thus sealing the gap between the movable sleeve 1 and the battery top cover. At the same time, the inner threaded cylinder 201 is threaded to the periphery of the outer threaded cylinder 103, sealing the top of the movable sleeve 1 and providing a sealed electrical connection for the battery electrodes.
