Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of batteries, in particular to a circular battery with high stability. Background Art
[0002] A circular battery is a common chemical battery, also known as a button battery, which mainly consists of four basic components: a primary battery, a sealing gasket, a metal shell, and a bottom cover. Due to its portability, high energy density, and long lifespan, etc., the circular battery is widely used in various portable electrical appliances and electronic products. The traditional circular battery is generally protected by an integrated shell. When the circular battery is impacted, the shell is prone to dent and deform. Since the traditional integrated shell cannot collapse and absorb energy, the deformation of the shell will further invade and squeeze the battery core, resulting in damage to the circular battery, affecting the normal use of the circular battery, and thus causing economic losses. Therefore, a circular battery with high stability is proposed. Summary of the Utility Model
[0003] The purpose of the utility model is to solve any of the above technical problems, and thus a circular battery with high stability is proposed, which includes a shell and a battery body. The battery body is fixedly installed inside the shell. The top of the battery body is provided with a positive terminal. The top of the shell is installed with a top cover, and multiple buffer pads are installed on the side wall of the shell.
[0004] Furthermore, a boss is provided at the top of the shell. The top cover is in a circular ring shape, and a groove is opened at the bottom of the top cover. The size of the boss is adapted to the size of the groove.
[0005] Furthermore, multiple installation slots are opened at the top of the boss. The installation slots are arranged in an equidistant and circumferential manner. Multiple buckles are provided in the groove of the top cover. The buckles are arranged in an equidistant and circumferential manner.
[0006] Furthermore, the buckles are snap-fitted and fixed in the installation slots, and the top cover is fixed on the boss by a dotting process.
[0007] Furthermore, multiple buffer grooves are opened on the side wall of the shell in an equidistant and circumferential manner. The buffer grooves are arc-shaped. The number of the buffer pads is the same as that of the buffer grooves. The buffer pads are snap-fitted and fixed in the buffer grooves.
[0008] Furthermore, the length of the buffer pad is slightly less than the length of the buffer groove, and the buffer pad can undergo elastic deformation.
[0009] Advantageous Effects: By arranging multiple buffer grooves in the shell and providing buffer pads in the buffer grooves, when the shell is impacted and dents and deforms, the buffer grooves and the buffer pads can collapse and absorb energy, effectively preventing the deformed shell from further invading and squeezing the battery body, resulting in damage to the battery body, and significantly improving the safety and stability of the battery body.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0017] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model.
[0018] Next, a circular battery with high stability according to an embodiment of the present utility model will be described with reference to the accompanying drawings, as Figures 1 to 4 shown. The circular battery with high stability includes an outer shell 1 and a battery body 2. The battery body 2 is fixedly installed in the outer shell 1. A positive terminal 201 is provided at the top of the battery body 2. A top cover 3 is installed at the top of the outer shell 1, and a plurality of buffer pads 4 are installed on the side wall of the outer shell 1.
[0019] Preferably, a boss 101 is provided at the top of the outer shell 1. The top cover 3 is in a circular ring shape, and a groove 301 is opened at the bottom of the top cover 3. The size of the boss 101 is adapted to the size of the groove 301.
[0020] Preferably, a plurality of mounting grooves 102 are opened at the top of the boss 101. The mounting grooves 102 are arranged at equal intervals in a circumferential manner. A plurality of buckles 302 are provided in the groove 301 of the top cover 3. The buckles 302 are arranged at equal intervals in a circumferential manner.
[0021] Preferably, the buckle 302 is snap-fitted and fixed in the mounting groove 102, and the top cover 3 is fixed on the boss 101 by a dotting process.
[0022] In a specific embodiment: The battery body 2 is nested and fixed inside the outer shell 1. There is a clearance fit between the buckle 302 and the installation groove 102. When installing the top cover 3 onto the boss 101, first drip glue into the installation groove 102, and then insert the buckle 302 into the installation groove 102. The buckle 302 is fixed in the installation groove 102 by the glue, thereby realizing the fixed installation of the top cover 3 on the boss 101.
[0023] Among them, the dispensing process is mainly a conventional means for those skilled in the art, and its specific process will not be elaborated.
[0024] Preferably, a plurality of buffer grooves 103 are equidistantly and circumferentially formed on the side wall of the outer shell 1. The buffer grooves 103 are arc-shaped. The number of buffer pads 4 is the same as that of the buffer grooves 103, and the buffer pads 4 are snap-fitted and fixed in the buffer grooves 103.
[0025] Preferably, the length of the buffer pad 4 is slightly less than the length of the buffer groove 103. The buffer pad 4 can undergo elastic deformation. By setting the length of the buffer pad 4 to be slightly less than the length of the buffer groove 103, there is a certain gap after the buffer pad 4 is installed in the buffer groove 103, which can provide space for the deformation of the buffer pad 4.
[0026] In a specific embodiment: When the outer shell 1 is impacted and dented and deformed, the deformation of the outer shell 1 can be effectively absorbed through the arrangement of the plurality of buffer grooves 103, avoiding the deformation of the outer shell 1 from further invading the interior and pressing the battery body 2, resulting in damage to the battery body 2. At the same time, by arranging the buffer pads 4 in the buffer grooves 103, the buffer pads 4 can undergo elastic deformation in the buffer grooves 103, and the buffer pads 4 can effectively absorb energy through deformation, further reducing the risk of the deformation of the outer shell 1 from further invading the interior and pressing the battery body 2. Through the arrangement of the plurality of buffer grooves 103 and the buffer pads 4, it can effectively prevent the dented deformation of the outer shell 1 from further invading and squeezing the battery body 2, resulting in damage to the battery body 2, and significantly improving the safety and stability of the battery body 2.
[0027] Working principle: During use, the top cover 3 is fixedly installed on the boss 101 of the outer shell 1 through the dispensing process. When the outer shell 1 is impacted and dented and deformed, the deformation of the outer shell 1 can be effectively absorbed through the arrangement of the plurality of buffer grooves 103, avoiding the deformation of the outer shell 1 from further invading the interior and pressing the battery body 2, resulting in damage to the battery body 2. At the same time, by arranging the buffer pads 4 in the buffer grooves 103, the buffer pads 4 can undergo elastic deformation in the buffer grooves 103, and the buffer pads 4 can effectively absorb energy through deformation, further reducing the risk of the deformation of the outer shell 1 from further invading the interior and pressing the battery body 2. Through the arrangement of the plurality of buffer grooves 103 and the buffer pads 4, it can effectively prevent the dented deformation of the outer shell 1 from further invading and squeezing the battery body 2, resulting in damage to the battery body 2, and significantly improving the safety and stability of the battery body 2.
