Description

Technical Field

[0001] The invention relates to the technical field of conductors, and in particular to a cylindrical battery based on optimized conductive electrode columns. Background Art

[0002] Cylindrical batteries are batteries with a cylindrical shell, usually used for power supply and energy storage. They are widely used in many electronic devices. The poles of cylindrical batteries are the conductive parts of the battery's internal electrochemical reaction to generate current, which are divided into positive and negative poles. The battery is connected to the external circuit through the conductive poles to complete the storage and release of electrical energy. When the battery is placed in the battery slot of an external device and is not used for a long time, the positive and negative poles of the battery in the battery slot are still in contact with the conductive electrode sheet in the battery slot. Even if the device is not in use, it will consume a certain amount of current on the battery, causing deep discharge damage to the battery after a long time. In addition, even if it is not used, the battery will self-discharge. Long-term insertion in the device may cause the risk of poor contact or short circuit. Severe battery leakage will damage the device. Usually, the battery is removed from the battery slot of the external device when it is not used for a long time.

[0003] Most of the existing battery conductive electrodes are fixed, which also results in a certain length of the battery. When the external device is not used for a long time, the electrodes at both ends of the battery are still at risk of contacting the battery slot electrodes, and the battery needs to be taken out of the battery slot and stored separately. However, when it is used next time, the placement of the battery may be forgotten, resulting in the need to purchase another battery, which increases the cost of use and delays the use of the equipment. In addition, the battery length is relatively fixed. When the battery slot length is designed to be too long, it cannot contact the battery electrode well to achieve a stable electrical connection, and the use effect is not good. For this reason, we propose a cylindrical battery based on conductive electrode optimization. Summary of the invention

[0004] The purpose of the present invention is to provide a cylindrical battery based on conductive electrode optimization to solve the problem mentioned in the above background technology that most of the existing battery electrodes are fixed, and when the external device is not used for a long time, it is not convenient to disconnect the contact between the battery electrode and the electrode in the battery slot when the battery is placed in the battery slot of the external device. In addition, when the error in the battery slot design is too long, it is not possible to make the battery electrode and the electrode in the battery slot have stable contact to improve the stability of the conductive connection.

[0005] To achieve the above object, the present invention provides the following technical solution: a cylindrical battery based on conductive electrode column optimization, comprising:

[0006] An aluminum shell, wherein a protective component for external collision buffering is detachably connected to the outer surface of the aluminum shell;

[0007] A first conductive electrode column is arranged on the lower surface of the aluminum shell;

[0008] A conductive component is disposed on the aluminum shell;

[0009] The conductive component includes a base, a second conductive electrode column and an elastic structure. The base is riveted on the aluminum shell. The inner side of the base is electrically connected to the second conductive electrode column through the elastic structure, and the outer surface of the second conductive electrode column has a threaded portion to cooperate with the base when the battery is not discharging to the outside.

[0010] Preferably, the elastic structure includes a spring, a spring wire, a ring tube, a slider and a slide groove, the base is provided with a slide groove, a ring tube is fixed to the lower surface of the second conductive electrode column, and a slider matching the slide groove is provided on the side wall of the ring tube, a spring is provided on the inner side of the ring tube, and one end of the spring is in contact with the base, and the inner side of the spring has a spring wire that electrically connects the base with the second conductive electrode column.

[0011] Preferably, an annular groove for the slider to rotate is provided at the inner lower end of the slide groove along the circumferential direction of the base, and a threaded groove cooperating with the annular cylinder is provided at the lower end of the inner surface of the base.

[0012] Preferably, the slider is rectangular, and two sliders are symmetrically arranged along the second conductive electrode column.

[0013] Preferably, the buffer assembly includes a first protective cover, a second protective cover, a cavity and a rubber block. The first protective cover and the second protective cover are arranged side by side on the upper and lower ends of the aluminum shell, and the corresponding ends of the first protective cover and the second protective cover are matched through a threaded portion. The outer surface of the aluminum shell is provided with a stopper to limit the movement of the other end of the first protective cover or the second protective cover. There is a cavity between the first protective cover and the aluminum shell, and a rubber block is provided at the other end of the inner surface of the first protective cover corresponding to the stopper.

[0014] Preferably, the inner surface of the first protective cover is provided with a bauxite layer, and the inner side of the bauxite layer is provided with an aluminum foil layer.

[0015] Preferably, the cross section of the rubber block is "L"-shaped, and the rubber block is provided at two locations, with the other rubber block being provided at the other end of the inner surface of the second protective cover.

[0016] Preferably, a sealing ring is provided on the outer surface of the conductive component inside the aluminum shell, the top of the aluminum shell has a lower plastic that insulates the conductive component, and the lower surface of the conductive component is provided with a current collecting plate connected to the battery cell inside the aluminum shell.

[0018] Preferably, an explosion-proof valve sheet is provided on the edge of the lower surface of the aluminum shell.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention avoids the problem of the length of the battery being fixed by providing a base, a second conductive electrode column and an elastic structure. When the battery is not used for a long time, the battery is still electrically connected to the electrode inside the battery slot, which causes the battery to discharge to the outside for a long time and cause short circuit damage to the battery itself. When not in use, the length of the battery can be adjusted so that the conductive component does not contact the electrode in the battery slot, thereby disconnecting the circuit and reducing the inconvenience of having to take the battery out of the battery slot and place it elsewhere. The operation is simple and the conductive component can be elastically stretched to electrically connect to the electrode in the battery slot, thereby ensuring the stability of the circuit. The battery of the present invention is made of an aluminum shell, which greatly reduces the cost of traditional steel shell production and increases the practicality of the device.

[0021] (2) By providing the first protective cover, the second protective cover, the cavity and the rubber block, the battery is prevented from directly contacting and colliding with the outside during use or transportation, thereby preventing the battery from causing significant collision damage. The device can perform elastic buffering well, and by arranging a bauxite layer and an aluminum foil layer on the inner side of the first protective cover and the second protective cover, the aluminum shell can be isolated from the outside, thereby reducing the leakage of flames to the outside when the battery explodes, reducing damage to the outside, and improving the safety of use.

[0042] Preferably, the buffer assembly includes a first protective cover 2, a second protective cover 3, a cavity 6 and a rubber block 16.

At the same time, it expands when exposed to heat and can well seal the rupture of the first protective cover 2 to increase the fire prevention and heat insulation effect. The inner side of the bauxite layer 14 has an aluminum foil layer 15 for better temperature reflection and reducing the heat transferred to the outside when the battery explodes.

[0044] Preferably, the cross section of the rubber block 16 is "L"-shaped, and the rubber block 16 is provided at two locations, with the other rubber block 16 being provided at the other end of the inner surface of the second protective cover 3 to facilitate better elastic buffering.

[0048] The working principle and use process of the present invention are as follows: when in use, the cylindrical aluminum shell 1 with the battery core can be installed inside the battery slot to supply power to external devices. During the power supply process, the first conductive electrode column 4 is also connected to the electrode sheet in the battery slot. In addition, the elastic force of the spring 903 can well connect the second conductive electrode column 902 to another electrode sheet in the battery slot to maintain stable power supply. When not in use, the second conductive electrode column 902 can be pressed to move toward the base 901, and then the ring tube 905 can be used to cooperate with the threaded groove 909 of the base 901 to shorten the length of the entire battery. At this time, even if the battery is placed in the battery slot, due to the battery One end cannot be connected to the electrode sheet of the device, thereby reducing the discharge of the battery to the external device when it is placed for a long time. During the transportation of the aluminum shell 1, the cavity 6 and the rubber block 16 formed between the outer surface of the aluminum shell 1 and the first protective cover 2 and the second protective cover 3 can easily avoid direct collision between the aluminum shell 1 and external objects. The cavity 6 and the rubber block 16 can provide an elastic ring to improve the safety of the aluminum shell 1. Further, when the aluminum shell 1 fails and explodes, the flame of the aluminum shell 1 can be isolated from the outside through the bauxite layer 14 and the aluminum foil layer 15 to reduce damage to the outside. The first protective cover 2 and the second protective cover 3 are easy to disassemble and assemble, thereby improving the practicality of the device.
