Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a cylindrical battery and an electronic device thereof. Background Art

[0002] Game peripherals, also known as game accessories or game peripheral devices, refer to devices that are used in conjunction with game consoles, computers, virtual / augmented reality headsets, etc. to enhance the gaming experience or provide additional functions. These devices have a broad market prospect. Common game peripherals include headsets, joystick controllers, gloves, positioning sensors, etc.

[0003] To enhance the user experience, game peripherals usually adopt a wireless connection method. Therefore, batteries, especially rechargeable batteries, are one of the important components of game peripherals. However, for a cylindrical battery, when it is installed in a game peripheral, the electrodes at both ends have been connected to the power supply circuit by the battery compartment. When charging is required, the battery needs to be removed from the battery compartment, which results in a poor user experience of the game peripheral.

[0004] To avoid the cumbersome steps of removing the battery during charging, the electrodes at both ends of the cylindrical battery can be guided to the side wall of the cylindrical battery, thereby increasing the electrical contact positions where the battery can be charged. In the prior art, a cylindrical battery for game peripherals usually consists of a flat-top battery, an insulating lining, a false cap, and a housing. The front end of the false cap is provided with a top protrusion, and the rear end extends to the side wall of the flat-top battery to realize guiding the electrodes to the side wall of the battery.

[0005] However, in the current solution, the false cap needs to be welded to the flat-top battery. Thus, problems such as false soldering, explosion soldering, and floating of the false cap are difficult to completely solve, which affects the quality of the battery. At the same time, the current solution also has disadvantages such as more processes and higher costs. Summary of the Utility Model

[0028] To better illustrate the purpose, technical solution, and advantages of the present utility model, the following detailed description of the specific embodiments of the present utility model will be further described with reference to the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0029] Such as Figures 1 to 3As shown in the figure, a cylindrical battery according to an embodiment of the present utility model is provided. The cylindrical battery is composed of a battery core 10, a lining insulation component 20, an electrode lead-out component 30, and a housing component 40. Among them, the battery core 10 is a rechargeable nickel-metal hydride battery and is in the shape of a cylinder. An electrode cap 11 is provided at the first end of the battery core 10, while the second end of the battery core 10 is a flat structure without a convex cap. In other words, the battery core 10 is a top-convex battery. The electrode lead-out component 30 is composed of a cap structure 31, a top structure 32, and a side structure 33. Generally speaking, the electrode cap 11 is the positive electrode of the battery. The electrode lead-out component 30 is used to be arranged at the first end of the battery core 10, so as to lead out the electrode of the electrode cap 11 to the side wall of the battery core 10. When the electrode lead-out component 30 is installed at the first end of the battery core 10, the cap structure 31 is in contact with the electrode cap 11 arranged on the battery core 10, the top structure 32 is located at the first end of the battery core 10, and the side structure 33 is located at the side wall of the battery core 10. At the same time, the top structure 32 is electrically connected to the cap structure 31, and the side structure 33 is electrically connected to the top structure 32. The electrode lead-out component 30 has been electrically conductively connected to the positive electrode of the battery core 10. Correspondingly, the lining insulation component 20 is used to isolate the contact between the electrode lead-out component 30 and the negative electrode of the battery core 10. The housing component 40 is arranged on the outermost side of the battery core 10, the lining insulation component 20, and the electrode lead-out component 30, so as to play a role in protecting the cylindrical battery and stabilizing each component.

[0030] The working principle of this embodiment is as follows: After the electrode lead-out component 30 is fixedly connected to the battery core 10, the electrode cap 11, which is the positive electrode of the battery core 10, contacts and conducts electricity with the cap structure 31 of the electrode lead-out component 30, and is led out to the side wall of the battery core 10 through the top structure 32 and the side structure 33 of the electrode lead-out component 30 in sequence. When in use, the cap structure 31 of the electrode lead-out component 30 can replace the electrode cap 11 of the battery core 10 as the first lead-out positive electrode of the cylindrical battery and supply power to electronic devices such as game peripherals. At the same time, the side structure 33 of the electrode lead-out component 30 can be used as the second lead-out positive electrode of the cylindrical battery, so that electronic devices such as game peripherals can directly charge the cylindrical battery through the side structure 33.

[0031] It can be seen that for the cylindrical battery of the present utility model, by using the battery core 10 with the electrode cap 11 and cooperating with the electrode lead-out component 30 with the cap structure 31, the top structure 32, and the side structure 33, the battery core 10 and the electrode lead-out component 30 only need to be connected through the physical contact between the electrode cap 11 and the cap structure 31, reducing the welding process, avoiding problems such as virtual soldering, explosion soldering, floating of false caps, etc., and avoiding the problem of battery charge and discharge failure caused by poor spot welding, realizing the improvement of battery quality stability, the simplification of the manufacturing process, and the reduction of manufacturing costs.

[0032] Reference Figure 2 and Figure 3 Specifically, in this embodiment, the cap structure 31, the top structure 32, and the side structure 33 in the electrode lead component 30 are integrally formed by stamping with a metal conductive material. Therefore, each part of the electrode lead component 30 does not need to be welded, and the processing efficiency is high. In this embodiment, the side structure 33 is in the shape of a cylindrical surface, the top structure 32 is in the shape of a circle, and the top structure 32 and the side structure 33 are combined to form a cap shape, which matches the first end of the cylindrical battery. The cap structure 31 is also in the shape of a cap, which matches the electrode cap 11 of the battery cell 10. The shape of the electrode lead component 30 is easy to process, has a large area, and can be firmly arranged on the cylindrical battery.

[0033] Reference Figure 2 and Figure 3 Specifically, in this embodiment, the first end of the battery cell 10 is configured as the positive electrode of the battery, while the second end and the side wall of the battery cell 10 are configured as the negative electrode of the battery. Thus, the second end of the battery cell 10 can be used as the first lead-out negative electrode for discharging connection. At the same time, the side wall of the battery cell 10 can be used as the second lead-out negative electrode for charging connection. However, the electrode lead component 30 cannot directly contact the side wall of the battery cell 10. The inner lining insulating component 20 covers the side wall of the battery cell 10 to isolate the contact between the electrode lead component 30 and the negative electrode of the battery cell 10. For this purpose, the inner lining insulating component 20 covers the edge of the first end of the battery cell 10 to isolate the edge at the top of the outer wall of the battery cell 10 from the top structure 32 of the electrode lead component 30. At the same time, the inner lining insulating component 20 also covers the first part of the side wall of the battery cell 10 adjacent to the first end to isolate the outer wall of the battery cell 10 adjacent to the first end from the side structure 33 of the electrode lead component 30. The inner lining insulating component 20 also exposes the second part of the side wall of the battery cell 10 near the second end. The second part of the side wall of the battery cell 10 is used as the second lead-out negative electrode. Preferably, the length of the side structure 33 of the electrode lead component 30 is less than the side length of the inner lining insulating component 20 to further avoid the contact between the side structure 33 and the outer wall of the battery cell 10.

[0034] In order to protect the cylindrical battery, the outer shell component 40 is arranged on the outermost side of the cylindrical battery. In order to expose the second lead-out positive electrode and the second lead-out negative electrode, the outer shell component 40 is provided with a first opening 41 and a second opening 42. The first opening 41 exposes the side structure 33 of the electrode lead component 30, and the second opening 42 exposes the side wall of the electrode lead component 30. The outer shell component 40 is formed by heat shrinking a heat shrinkable tube, so that the outer shell component 40 closely fits on the outermost side of the cylindrical battery, while protecting and fixing the battery cell 10, the inner lining insulating component 20, and the electrode lead component 30.

[0035] It is understandable that in other embodiments according to the present utility model, the negative electrode of the battery cell 10 can be shared for charging and discharging. The negative electrode of the battery cell 10 is only provided at the second end. Further, the housing component 40 can be provided with only the first opening 41.

[0036] It is understandable that in other embodiments according to the present utility model, the electrode lead-out component 30 may not be provided in a cap shape, that is, the top structure 32 and the side structure 33 can be provided with voids, as long as the fixing function of the electrode lead-out component 30 with the battery cell 10 can be realized, and the electrode can be led out from the electrode cap 11 of the battery cell 10 to the outer wall of the battery cell 10.

[0037] It is understandable that in other embodiments according to the present utility model, the battery cell 10 can also be a rechargeable battery such as a lithium-ion battery or a lithium iron phosphate battery configured in a cylindrical shape.

[0038] The above embodiments mainly describe the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
