[0030] In order to solve the technical problem of the hard-on-hard assembly process in the related technology and the safety risk, the present application provides a battery that realizes a soft connection through a first buffer part and a second buffer part, thereby improving the overall shock resistance of the battery and the safety of the battery and extending the service life of the battery.

[0031] In some exemplary embodiments, Figure 1 As shown, a battery can store or discharge energy. The battery is suitable for electronic equipment products that have strict requirements on vibration, drop, rolling, sound quality and sound effects, and provides power for electronic equipment to ensure that the electronic equipment can be used normally and meet the needs of users.

[0032] Refer to the picture - Figure 5 As shown, the battery includes a cell module 1, a first buffer 2, a chip assembly 3, a shell 4 and a second buffer 5, which are assembled and connected to facilitate the use of the battery.

[0033] The battery module 1 has multiple battery cells 11, which are suitable for products with different numbers of battery cells and different series and parallel modes. The battery cell 11 is, for example, a cylindrical battery cell, which has the advantages of high standardization, high production efficiency, high energy density, and high safety. It is convenient to combine and replace with other equipment or battery packs, and can store more energy in a smaller volume, realizing large energy storage, and meeting the user's demand for electricity. Exemplarily, the cylindrical battery cell includes two electrodes, an electrolyte, a shell, and a hollow PC sheet. The shell is usually made of metal or plastic, has good mechanical strength and corrosion resistance, and can improve the safety of the battery. The two electrodes are, for example, a positive electrode and a negative electrode, respectively, to realize the reflux and discharge of the battery. The positive electrode and the negative electrode are correspondingly arranged at the two axial ends of the cylindrical battery cell. The specific corresponding position shall be subject to the actual situation.

[0034] The plurality of battery cells 11 are arranged in sequence along the radial direction thereof, and the number of battery cells may be two, three or four, for example, depending on the actual situation. In the present application, two are taken as an example for further explanation.

[0035] Reference Figure 2 , Figure 3 As shown, the first buffer 2 is arranged between two adjacent battery cells 11 to achieve a soft connection between the battery cells 11, improve the shock resistance, and prevent the battery cells 11 from colliding with each other and being damaged, which affects the safety of the battery cell module 1. Among them, the first buffer 2 is, for example, foam, which has high density and good flexibility. It can effectively withstand external impact or vibration, absorb or scatter external impact force, provide effective protection, and thus protect the interior of the battery cell module 1. And foam is an environmentally friendly material and will not pollute the environment. The first buffer 2 can be a sheet or block structure, as long as it can separate the two battery cells 11, saving costs.

[0036] Reference Figure 2-Figure 4 As shown, the chip assembly 3 is, for example, disposed at the first end 14 of the battery cell module 1 , and the chip assembly 3 is electrically connected to the battery cell module 1 to facilitate control of the charging and discharging of the battery.

[0037] Reference Figure 2 , Figure 5 As shown, the shell 4 is mounted on the battery module 1 to ensure the flatness of the battery appearance, realize the assembled structure, and protect the battery module 1 to avoid damage to the inside of the battery.

[0038] The second buffer member 5 is attached to the outside of the housing 4 and protrudes from the housing 4 to reduce the shock of the battery as a whole and improve the safety of the battery as a whole. When the battery is installed in the battery compartment of the electronic device, the second buffer member 5 can avoid direct contact between the battery and the inner wall of the battery compartment, achieve soft connection, and reduce safety hazards. The second buffer member 5 is, for example, foam, and its performance has been described in detail in the above example, and will not be repeated here.

[0039] In some examples, the second buffer member 5 includes a first ring 51 and a second ring 52, which are respectively mounted on the housing 4. The first ring 51 and the second ring 52 are respectively close to both ends of the housing 4, which reduces material costs and can also achieve earthquake resistance.

[0040] In this embodiment, if Figure 2 , Figure 4 As shown, the chip assembly 3 includes a control module 31 (Pulse Code Modulation, PCM for short), a chip module 32 (Process Chip, PC for short) and a terminal portion 33 .

[0041] The control module 31 is, for example, a plate-shaped structure and is electrically connected to the battery module 1 to realize the corresponding control function. The chip module 32 is, for example, also a sheet-shaped structure and is attached to a side of the control module 31 away from the battery module 1 and is electrically connected to the control module 31 .

[0042] The terminal portion 33 is connected to the control module 31 and extends from the housing 4 to facilitate connection with the electronic device. The terminal portion 33 includes, for example, a wire body 331 and a terminal connector 332. One end of the wire body 331 is welded to the control module 31, and the other end of the wire body 331 is connected to the terminal connector 332. The terminal connector 332 is detachably connected to the electronic device to achieve circuit connectivity.

[0043] The outer side of the terminal part 33 is wrapped with a flexible member 34 , which is also foam, for example, to protect the terminal part 33 .

[0044] In some examples, the flexible member 34 includes a first flexible sleeve 341 and a second flexible sleeve 342, wherein the first flexible sleeve 341 is sleeved on the wire body 331 of the terminal portion 33 to wrap and protect the wire body 331. The terminal connector 332 extends out of the first flexible sleeve 341 to ensure that it can be plugged into an electronic device.

[0045] The second flexible sleeve 342 is sleeved on the first flexible sleeve 341 and is close to the housing 4. The second flexible sleeve 342 and the first flexible sleeve 341 achieve double protection, further protecting the wire 331 near the housing 4 to avoid breakage or leakage at the connection, etc. The foam has good insulation and can improve the safety of the terminal part 33. The length of the second flexible sleeve 342 is less than that of the first flexible sleeve 341, achieving local protection and effectively reducing costs.

[0046] In this embodiment, if Figure 2 , Figure 4As shown, the chip assembly 3 further includes a cushion layer 35, which is disposed between the control module 31 and the chip module 32. The cushion layer 35 can protect the control module 31 and the chip module 32, form a partial separation, and prevent the control module 31 and the chip module 32 from colliding with each other. The cushion layer 35 is made of, for example, a silicone material, so that it has high temperature resistance, corrosion resistance, aging resistance, plasticity, etc. The control module 31 and the chip module 32 will heat up during operation, and the cushion layer 35 can be used for a long time in a high temperature environment without deformation, expansion, or melting.

[0047] In some examples, the cushion layer 35 includes, for example, a cushion plate 351 and two supporting bosses 352, and the two supporting bosses 352 are disposed on the cushion plate 351. The cushion plate 351 is connected to the battery cell module 1, and the two supporting bosses 352 are connected to the control module 31, and support the control module 31 to improve the stability of the control module 31. The cushion plate 351 has good comprehensive durability, can maintain its mechanical strength and elasticity for a long time, and effectively avoid collapse.

[0048] In this embodiment, if Figure 2 , Figure 3 As shown, the battery cell module 1 further includes at least one first nickel sheet 12 and at least one second nickel sheet 13 .

[0049] The first nickel sheet 12 is disposed at the first end 14 of the battery cell module 1 and connected to the chip assembly 3 . The second nickel sheet 13 is disposed at the second end 15 of the battery cell module 1 .

[0050] The number of the first nickel sheets 12 is consistent with the number of the battery cells 11, for example, to achieve a one-to-one correspondence, or one first nickel sheet 12 may be provided to connect to all the battery cells 11. The second nickel sheet 13 is provided in the same manner as the first nickel sheet 12, and will not be described in detail herein. The number of the first nickel sheet 12 and the second nickel sheet 13 shall be determined according to the actual situation, such as Figure 3 As shown, the first nickel sheet 12 in the present application is exemplified by two, and the second nickel sheet 13 is exemplified by one.

[0051] In some examples, the first nickel sheet 12 includes a first body 121 and a first lead-out section 122. The first body 121 is connected to the battery cell module 1. One end of the first lead-out section 122 is connected to the first body 121, and the other end is bent relative to the first body 121. The first lead-out section 122 can be overlapped to the surface of the control module 31 to achieve connection.

[0052] The second nickel sheet 13 is connected to the chip assembly 3 via the voltage collection line 16 to achieve electrical connection. The control module 31 in the chip assembly 3 is provided with a through hole 311 so that the voltage collection line 16 can pass through the through hole 311 to connect to the chip module 32 .

[0053] In some examples, the second nickel sheet 13 includes, for example, a second body 131 and a second lead-out section 132, the second body 131 is connected to the battery module 1, one end of the second lead-out section 132 is connected to the second body 131, and the other end is bent relative to the second body 131. One end of the voltage collection line 16 is connected to the second lead-out section 132, and the other end of the voltage collection line 16 passes through the through hole 311 and is connected to the chip module 32.

[0054] Nickel sheets are used to connect the battery cells 11, etc., so that they have good conductivity, corrosion resistance and high temperature resistance, are easy to process, and maintain stable performance.

[0055] In this embodiment, if Figure 2 , Figure 5 As shown, the shell 4 includes a cylinder 41 , a first cover 42 and a second cover 43 to protect the battery module 1 .

[0056] The cylinder 41 is mounted on the battery module 1 to wrap the battery module 1 and protect the battery module 1 in the circumferential direction. The first cover 42 is disposed at the first end 14 of the battery module 1 and is connected to the cylinder 41 to shield the chip module 32 and prevent the chip module 32 from being exposed, which affects the service life and safety. The second cover 43 is disposed at the second end 15 of the battery module 1 and is connected to the cylinder 41 to shield the second nickel sheet 13 and prevent the inside from being exposed.

[0057] The cylinder 41 is, for example, a thermoplastic sleeve (thermoplastic engineering plastic <compliant with UL94V-0>) or a plastic shell, which has good insulation and wear resistance, can effectively protect the safety of the battery under high voltage environment, and is waterproof and moisture-proof, and can protect the battery from damage in a humid environment.

[0058] The first cover 42 and the second cover 43 are made of a flexible material, such as foam, and the first cover 42 and the second cover 43 respectively provide axial protection for the battery, and cooperate with the cylinder 41 to further enhance the overall anti-vibration capability of the battery.

[0059] The present disclosure also provides an electronic device, including a device body (not shown in the figure) and a battery as in the above embodiment, which is used to power the electronic device to ensure that the electronic device can be used normally. The electronic device is, for example, a portable device such as a speaker, a mobile phone, a smart home, a drone, and other products that need to realize shock absorption, vibration prevention, and drop prevention structures.

[0060] The device body is provided with a battery compartment, in which the battery is arranged, and connected through a terminal connector. The outer wall of the battery is provided with a second buffer member to reduce friction or impact between the battery and the battery compartment, improve the safety of the battery during use, and extend the battery life.

[0061] The above batteries can be used in products with strict requirements on vibration, drop, roll, sound quality and sound effects. If applied to speakers, the vibration problem can be solved through soft connection, while considering anti-vibration, anti-drop risks and roll test requirements.

[0062] In the related art, there is an acetate cloth + silicone ring process or a glue dispensing process to achieve earthquake resistance. However, there are many types of acetate cloth + silicone rings, which are not easy to choose, and the types are uneven. Although the glue dispensing process can use glue dispensing equipment, the final effect is not easy to control because the glue is flowing. The battery in this application has been greatly optimized in terms of material category and assembly process. While reducing material costs, the assembly process has also been relatively simplified. For example, soft contact is achieved by using foam, etc. The materials are simple, conventional and low-cost, which effectively solves the problem of high material costs. The battery in this application can be automated, with a simple assembly process and high production efficiency, which saves labor costs and simplifies the process.
