Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to micro-sized lithium batteries. Background Technology

[0002] Lithium-ion batteries, also known as lithium metal batteries, generally use manganese dioxide as the positive electrode material, lithium metal or its alloys as the negative electrode material, and a non-aqueous electrolyte solution. Due to their large capacity and stable charge and discharge, lithium-ion batteries are widely used in various electrical devices. However, current miniature lithium-ion batteries are not easy to recycle after use because the internal parts are difficult to disassemble, reducing recycling efficiency. Patent number CN212366131 U, entitled "A Miniature Lithium-ion Battery," describes a method of welding the upper and lower casings using welding plates. However, using welding technology on miniature lithium-ion batteries requires extremely high precision, and because the welding plates are located on the side face of the lithium-ion battery, it alters the battery's external shape, making it unsuitable for the current installation methods for miniature lithium-ion batteries. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a micro-miniature lithium battery.

[0004] According to the technical solution provided in the embodiments of this application, a micro-sized lithium battery includes an upper shell and a lower shell that wraps around the lower end of the upper shell. The bottom surface inside the lower shell is fixedly provided with a horizontally placed support ring by a support column. The lower end of the upper shell is located inside the support ring. A movable ring is movably sleeved on the support ring. The movable ring is fixedly connected to a vertically placed disassembly column. The disassembly column is fixed by the clamping of the upper shell and the lower shell. The disassembly column separates the upper shell and the lower shell by the movement of the movable ring on the support ring.

[0005] Furthermore, the upper end face of the disassembly column is located above the upper end face of the lower housing, making it convenient for disassembly.

[0006] Furthermore, the movable ring has an opening through which the support column can pass, facilitating the movement of the disassembly column on the support ring via the movable ring.

[0007] Furthermore, there are two disassembly columns, which are symmetrically placed at the center points of the upper shell to facilitate the rotation of the disassembly columns.

[0008] Furthermore, the end face of the disassembly column that abuts against the upper shell is an arc-shaped surface, which increases the contact area between the disassembly column and the outer end face of the upper shell, making disassembly easier.

[0009] Furthermore, the disassembly column can be tilted and rotated on the support ring via the movable ring, allowing the lower housing to detach from the upper housing.

[0010] In summary, the beneficial effects of this application are as follows: The device of this application is equipped with a disassembly column that can move at the connection between the upper and lower shells on a micro-sized button battery. The disassembly column can be directly pried open and rotated on the lithium battery to separate the upper and lower shells, which facilitates the disassembly and recycling of micro-sized lithium batteries. At the same time, the disassembly column in the device of this application does not increase the installation and use space of traditional lithium batteries, and has a wide range of applications.

[0017] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Micro-sized lithium batteries, such as Figure 1 As shown, the lower housing 2 wraps around the lower end of the upper housing 1, and the vertically placed disassembly column 6 is located between the lower housing 2 and the upper housing 1 and is clamped and fixed by the upper housing 1 and the lower housing 2.

[0020] like Figure 2 and Figure 3 As shown, a horizontally placed support ring 4 is fixed on the bottom surface of the lower housing 2 by a number of support columns 3, while two vertically placed disassembly columns 6 are movably connected to the support ring 4 through a movable ring 5, which can move on the support ring 4.

[0021] like Figure 4 As shown, the lower end face of the moving ring 5 is provided with an opening 51, and the width of the opening 51 is greater than the diameter of the support column 3, so that the moving ring 5 can pass through the support column 3 when it moves on the support ring 4.

[0022] When Figure 1 When the power in the micro-sized lithium battery shown is used up and needs to be recycled, first use a wrench to pry the two disassembly pins 6 outwards from the lower housing 2, causing a part of the lower housing 2 to separate from the upper housing 1. Then, hold down the lithium battery body (i.e., the upper housing 1), and then manually rotate (or use a pointed screwdriver) one hand (or one end of the screwdriver) and push one of the disassembly pins 6, causing the disassembly pin 6 to rotate on the lithium battery body. As the disassembly pin 6 rotates, the moving ring 5 on the lower end face of the disassembly pin 6 moves on the support ring 4, causing the disassembly pin 6 to separate the upper housing 1 from the lower housing 2. After separation, the disassembly pin 6 moves on the support ring 4 and then prys the lower housing 2 outwards, increasing the distance between the lower housing 2 and the upper housing 1. In this way, the upper housing 1 can be easily removed from the lower housing 2, realizing the recycling of the materials inside the upper housing 1 and the lower housing 2.

[0023] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and other solutions employed. Furthermore, the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
