Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to a cylindrical lithium battery that is easy to install. Background Technology

[0002] A lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Depending on the electrolyte material, lithium batteries can be divided into several types, the most common of which are lithium-ion batteries and lithium polymer batteries. Lithium-ion batteries use lithium alloy metal oxide as the positive electrode material and graphite as the negative electrode material, while lithium polymer batteries use polymers to gel liquid organic solvents or directly use all-solid-state electrolytes.

[0003] As disclosed in the patent application CN212676386U, this utility model discloses a novel lithium battery that is easy to install. It includes an upper casing and a lower casing. Several cylindrical springs are horizontally mounted on the top of the upper casing's inner cavity. A first rubber plate is fixedly connected to the bottom of each cylindrical spring, and an upper conductive plate is fixedly connected to the bottom of the first rubber plate. A lower conductive plate with the same structure as the upper conductive plate is mounted on the bottom of the lower casing's inner cavity. Multiple battery separators are horizontally mounted on the inner cavity of the lower casing. A circuit separator is located on the left side of the lower casing's inner cavity. Horizontal covers are located on both bottom sides of the upper casing, and longitudinal covers are located on the outer sides of the two horizontal covers. The upper and lower casings house the lithium battery within the inner cavity, protecting it from external impacts and preventing damage. Simultaneously, the battery separators separate each lithium battery, avoiding heat conduction between multiple batteries and reducing their lifespan.

[0004] Although the aforementioned patents utilize a combination of cylindrical springs, battery separators, and lateral caps to install lithium batteries, these patents, as well as most commercially available mounting structures for cylindrical lithium batteries, cannot be adjusted according to the battery's diameter. Since different brands and models of cylindrical lithium batteries vary in diameter, and existing mounting structures often only accommodate batteries of specific diameters, users encounter compatibility issues when replacing batteries. When the new battery diameter does not match the existing mounting structure, the user must replace the entire structure, increasing costs. Furthermore, during transportation or storage, mismatches between the cylindrical lithium battery's diameter and the mounting structure's dimensions can easily lead to loosening or insecure fixing during installation, resulting in displacement or dropping of the cylindrical lithium battery. Utility Model Content

[0005] The purpose of this invention is to provide a cylindrical lithium battery that is easy to install, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical lithium battery that is easy to install, including a fixing plate, wherein the top of the fixing plate is provided with a plurality of mounting structures.

[0007] The mounting structure includes a circular block fixedly connected to a fixed plate. A transmission block is rotatably connected to the bottom of the inner cavity of the circular block. A torsion spring is fixedly connected to the inner cavity of the transmission block. A positioning block is fixedly connected to one end of the torsion spring. One side of the positioning block is fixedly connected to the circular block. A transmission rod is fixedly connected to the top of the transmission block. The top end of the transmission rod extends through to the top of the circular block and is fixedly connected to a rotating block. The bottom of the rotating block is in contact with the circular block. Six guide grooves arranged in a ring are formed on the surface of the rotating block. A movable rod is slidably connected to the inner cavity of the guide groove. A moving rod is fixedly connected to the bottom of the movable rod. A limiting groove adapted to the moving rod is formed on the top of the circular block. A mounting plate is fixedly connected to one end of the limiting groove. The six mounting plates on opposite sides together form a mounting groove.

[0008] The inner cavity of the mounting slot is equipped with a cylindrical lithium battery.

[0009] Furthermore, in a preferred embodiment of this invention, a placement block is rotatably connected to the top of the rotating block, the bottom of the placement block is in contact with the circular block and the moving rod, and the top of the placement block is in contact with the cylindrical lithium battery.

[0010] Furthermore, as a preferred embodiment of this utility model, the top of the mounting plate is provided with an inclined surface, and the inner surface of the mounting plate is provided with anti-slip texture.

Whether the battery is large or small in diameter, it can be tightly adapted by adjusting the internal components of the installation structure. There is no need to equip each size of battery with a separate installation structure, which reduces the user's usage cost. Secondly, because it can fit batteries of different diameters tightly, it can effectively prevent the battery from becoming loose or not being fixed firmly after installation. During transportation and storage, it can prevent the battery from shifting or falling off the installation plate due to vibration or impact, thereby protecting the battery from damage and reducing potential safety risks.

[0022] As attached Figure 1 To be continued Figure 4 As shown: This embodiment provides a cylindrical lithium battery that is easy to install, including a fixing plate 1, and a plurality of mounting structures 2 are provided on the top of the fixing plate 1.

[0023] Mounting structure 2 includes a circular block 21 fixedly connected to the fixing plate 1. A transmission block 22 is rotatably connected to the bottom of the inner cavity of the circular block 21. A torsion spring 23 is fixedly connected to the inner cavity of the transmission block 22. A positioning block 24 is fixedly connected to one end of the torsion spring 23. One side of the positioning block 24 is fixedly connected to the circular block 21. A transmission rod 25 is fixedly connected to the top of the transmission block 22. The top end of the transmission rod 25 extends through to the top of the circular block 21 and is fixedly connected to a rotating block 26. The bottom of the rotating block 26 contacts the circular block 21, allowing rotation. The surface of block 26 has six guide grooves 27 arranged in a ring. A movable rod 28 is slidably connected to the inner cavity of the guide groove 27. A moving rod 29 is fixedly connected to the bottom of the movable rod 28. A through hole adapted to the transmission rod 25 is opened at the top of the moving rod 29. The surface of the transmission rod 25 is rotatably connected to the through hole. A limiting groove 210 adapted to the moving rod 29 is opened at the top of the circular block 21. A mounting plate 211 is fixedly connected to one end of the limiting groove 210. The six mounting plates 211 together form a mounting groove on opposite sides.

[0024] The inner cavity of the mounting slot is equipped with a cylindrical lithium battery 3.

[0025] Specifically, the top of the rotating block 26 is rotatably connected to the placement block 212, the bottom of the placement block 212 is in contact with the circular block 21 and the moving rod 29, and the top of the placement block 212 is in contact with the cylindrical lithium battery 3.

[0026] In this embodiment, the placement block 212 serves to separate the cylindrical lithium battery 3 from the guide groove 27, thus preventing the movement of the movable rod 28 in the inner cavity of the guide groove 27 from damaging the cylindrical lithium battery 3.

[0027] Specifically, the top of the mounting plate 211 is provided with a slope 213, and the inner surface of the mounting plate 211 is provided with anti-slip texture.

[0028] In this embodiment, the use of the inclined surface 213 and the anti-slip texture makes it easier for the user to place the cylindrical lithium battery 3 into the inner cavity of the mounting slot, and increases the friction between the mounting plate 211 and the surface of the cylindrical lithium battery 3.

[0029] Specifically, the top of the fixing plate 1 has several fixing grooves 4 that are adapted to the circular block 21.

[0030] In this embodiment, the fixing groove 4 provides space for the installation structure 2 to be connected to the fixing plate 1.

[0031] The working principle and usage process of this utility model are as follows: The user places the cylindrical lithium battery 3 vertically from top to bottom into the inner cavity of the mounting slot. Six mounting plates 211 simultaneously expand outwards according to the diameter of the cylindrical lithium battery 3. As the mounting plates 211 expand outwards, they drive six moving rods 29 to expand outwards as well. The moving rods 29 pull the movable rod 28 to slide within the inner cavity of the guide groove 27. Due to the shape of the guide groove 27, the movable rod 28 drives the rotating block 26 to rotate as it slides. The rotating block 26 drives the transmission rod 25 to rotate. 5. The torsion spring 23 is rotated and tightened by the transmission block 22. Under the elastic force of the torsion spring 23, the inner surfaces of the six mounting plates 211 are always in contact with the surface of the cylindrical lithium battery 3, thereby completing the installation of the cylindrical lithium battery 3 and the fixing plate 1. When it is necessary to separate the fixing plate 1 and the cylindrical lithium battery 3, the user can directly move the cylindrical lithium battery 3 upward to separate the cylindrical lithium battery 3 from the mounting plate 211. Under the elastic force of the torsion spring 23 and in cooperation with the above-mentioned related parts, the mounting plate 211 returns to its original position.

[0032] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0033] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
