Description

Technical Field

[0001] This invention relates to the field of conductor technology, and more specifically to a cylindrical battery based on optimized conductive electrode posts. Background Technology

[0002] Cylindrical batteries are batteries with a cylindrical casing, typically used for power supply and energy storage. They are widely used in many electronic devices. The terminals of a cylindrical battery are the conductive parts that generate current through the electrochemical reaction inside the battery, and are divided into positive and negative terminals. The battery is connected to an external circuit through the conductive terminals to complete the storage and release of electrical energy. When a battery is placed in the battery compartment of an external device and is not used for a long time, the positive and negative terminals of the battery in the battery compartment are still in contact with the conductive plates in the battery compartment. Even when the device is not in use, it will still consume a certain amount of current from the battery, leading to deep discharge damage to the battery after a long period of time. In addition, even when not in use, the battery will self-discharge. Leaving it plugged into the device for a long time may cause poor contact or short circuit. Severe battery leakage can damage the device. Usually, the battery should be removed from the battery compartment of the external device when it is not in use for a long time.

[0003] Existing battery terminals are mostly fixed, which results in a fixed battery length. When the external device is not used for a long time, there is still a risk that the terminals at both ends of the battery will come into contact with the battery tray electrodes. The battery needs to be removed from the battery tray and stored separately. However, when it is used again, the battery placement location may be forgotten, resulting in the need to purchase a new battery, increasing usage costs and delaying the use of the device. In addition, the fixed battery length means that if the battery tray is designed to be too long, it is not possible to make good contact with the battery terminals to achieve a stable electrical connection, resulting in poor performance. To address this, we propose a cylindrical battery based on optimized terminal terminals. Summary of the Invention

[0004] The purpose of this invention is to provide a cylindrical battery based on optimized conductive electrode posts, in order to solve the problems mentioned in the background art, where existing battery posts are mostly fixed. When the external device is not used for a long time, it is not easy to disconnect the contact between the battery posts and the electrode plates in the battery compartment. In addition, when there is a large error in the design of the battery compartment, it is not possible to make stable contact between the battery posts and the electrode plates in the battery compartment to improve the stability of the conductive connection.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cylindrical battery based on optimized conductive electrode posts, comprising:

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

[0007] The first conductive electrode post is disposed on the lower surface of the aluminum shell;

[0008] Conductive components are mounted on an aluminum casing;

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

[0010] The elastic structure includes a spring, a spring wire, a ring cylinder, a slider, and a groove. The base has a groove. The ring cylinder is fixed on the lower surface of the second conductive electrode post, and the side wall of the ring cylinder is provided with a slider that cooperates with the groove. The inner side of the ring cylinder is provided with a spring, and one end of the spring abuts against the base. The inner side of the spring has a spring wire that electrically connects the base and the second conductive electrode post.

[0011] The lower inner end of the slide groove is provided with an annular groove along the circumference of the base for the slider to rotate, and the lower inner surface of the base has a threaded groove that mates with the annular cylinder.

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

[0013] Preferably, the protective 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 sleeved 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 engaged by a threaded part. A stop block is provided on the outer surface of the aluminum shell to restrict 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. A rubber block is provided on the other end of the inner surface of the first protective cover corresponding to the stop block.

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

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

[0016] Preferably, a sealing ring is provided on the inner side of the aluminum shell on the outer surface of the conductive component, the top of the aluminum shell has a lower plastic layer that insulates the conductive component, and a current collector is provided on the lower surface of the conductive component that connects to the battery cell inside the aluminum shell.

[0017] Preferably, the upper surface of the aluminum shell is provided with an upper plastic, and a steel ring is fixed inside the upper plastic to prevent the conductive components from twisting. The lower surface of the steel ring protrudes downward to form a claw that cooperates with the upper plastic.

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

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) By providing a base, a second conductive electrode post, and an elastic structure, this invention avoids the problem of a fixed battery length. When the battery is not used for a long time, the battery and the electrode inside the battery compartment are still electrically connected, which leads to prolonged discharge of the battery to the outside and short circuit damage. This device can adjust the battery length when not in use so that the conductive component does not contact the electrode inside the battery compartment, thereby disconnecting the circuit. This reduces the inconvenience of having to remove the battery from the battery compartment and place it elsewhere. The operation is simple, and the conductive component can be effectively extended to make an electrical connection with the electrode in the battery compartment, ensuring the stability of the circuit. In addition, the battery of this invention is made of aluminum shell, which greatly reduces the cost of traditional steel shell construction and increases the practicality of the device.

[0021] (2) By setting up a first protective cover, a second protective cover, a cavity and a rubber block, the battery is prevented from directly contacting and colliding with the outside during use or transportation, which would cause significant impact damage to the battery. This device can provide good elastic buffering. Furthermore, by arranging a bauxite layer and an aluminum foil layer inside the first and second protective covers, the aluminum shell can be isolated from the outside, reducing the leakage of flames to the outside when the battery explodes, thus reducing external damage and improving the safety of use.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-10 This invention provides a technical solution: a cylindrical battery based on optimized conductive electrode posts, comprising:

[0035] The aluminum shell 1 has a detachable protective component on its outer surface to buffer against external collisions. This reduces the direct contact between the aluminum shell 1 of the battery and external objects, thus minimizing the impact. This device helps to buffer the impact and improve the safety of the battery cells inside the aluminum shell 1.

[0036] The first conductive electrode post 4 is disposed on the lower surface of the aluminum shell 1;

[0037] Conductive component 9 is disposed on aluminum shell 1;

[0038] The conductive component 9 includes a base 901, a second conductive electrode post 902, and an elastic structure. The base 901 is riveted to the aluminum shell 1. The second conductive electrode post 902 is electrically connected to the inner side of the base 901 through the elastic structure, which facilitates external discharge. At the same time, the elastic force of the elastic structure allows the second conductive electrode post 902 to contact the external conductive electrode sheet to achieve stable current transmission. The outer surface of the second conductive electrode post 902 has a threaded portion to cooperate with the base 901 when the battery is not discharging externally, which facilitates reducing the overall length of the battery. This avoids contact discharge with the electrode sheet inside the battery compartment after placement, making it convenient to store the battery when not in use.

[0039] Preferably, the elastic structure includes a spring 903, a spring wire 904, an annular cylinder 905, a slider 906, and a groove 907. The base 901 has a groove 907. The lower surface of the second conductive electrode post 902 is fixed with an annular cylinder 905, and the side wall of the annular cylinder 905 is provided with a slider 906 that cooperates with the groove 907, so as to facilitate the vertical up and down movement of the second conductive electrode post 902. The annular cylinder 905 is provided with a spring 903, and one end of the spring 903 abuts against the base 901, so as to facilitate the up and down movement of the second conductive electrode post 902. The inner side of the spring 903 has a spring wire 904 that electrically connects the base 901 and the second conductive electrode post 902, so that the second conductive electrode post 902 can be electrically connected to the battery cell inside the aluminum shell 1 through the base 901.

[0040] Preferably, the lower inner end of the slide groove 907 is provided with an annular groove 908 for the slider 906 to rotate around the base 901, and the lower inner surface of the base 901 has a threaded groove 909 that mates with the ring cylinder 905, so as to fix the ring cylinder 905 to the base 901 and restrict the up and down movement of the second conductive electrode post 902.

[0041] Preferably, the slider 906 is rectangular, and two sliders 906 are symmetrically arranged along the second conductive electrode post 902 to facilitate better vertical up-and-down movement of the second conductive electrode post 902.

[0042] Preferably, the protective assembly includes a first protective cover 2, a second protective cover 3, a cavity 6, and a rubber block 16. The first protective cover 2 and the second protective cover 3 are sleeved side by side on the upper and lower ends of the aluminum shell 1, and the corresponding ends of the first protective cover 2 and the second protective cover 3 are engaged by a threaded part, which facilitates the disassembly and maintenance of the first protective cover 2 and the second protective cover 3 in the later stage. A stop block 13 is provided on the outer surface of the aluminum shell 1 to restrict the movement of the other end of the first protective cover 2 or the second protective cover 3. There is a cavity 6 between the first protective cover 2 and the aluminum shell 1. A rubber block 16 is provided on the other end of the inner surface of the first protective cover 2 corresponding to the stop block 13, which facilitates elastic buffering through the cavity 6 and the rubber block 16.

[0043] Preferably, the inner surface of the first protective cover 2 is provided with a bauxite layer 14, which facilitates fire prevention and expands when heated, effectively sealing any cracks in the first protective cover 2 to enhance fire prevention and heat insulation. The inner side of the bauxite layer 14 has an aluminum foil layer 15, which facilitates better temperature reflection and reduces the heat transferred to the outside when the battery explodes.

[0044] Preferably, the cross-section of the rubber block 16 is "L" shaped, and there are two rubber blocks 16. The other rubber block 16 is located at the other end of the inner surface of the second protective cover 3, which facilitates better elastic cushioning.

[0045] Preferably, a sealing ring 10 is provided on the inner side of the aluminum shell 1 on the outer surface of the conductive component 9, and a lower plastic 7 is provided on the top of the aluminum shell 1 to insulate the conductive component 9. A current collector 11 connected to the battery cell inside the aluminum shell 1 is provided on the lower surface of the conductive component 9 to facilitate the effective conduction of the battery internal current to the second conductive electrode post 902 in the conductive component 9.

[0046] Preferably, an upper plastic 8 is provided on the upper surface of the aluminum shell 1, and a steel ring 12 is fixed inside the upper plastic 8 to prevent the conductive component 9 from twisting. The lower surface of the steel ring 12 protrudes downward to form a claw 121 that cooperates with the upper plastic 8, which facilitates the improvement of the torque effect at the conductive component 9 and increases the firmness.

[0047] Preferably, an explosion-proof valve plate 5 is provided on the lower surface edge of the aluminum shell 1, which facilitates the release of excessive pressure when abnormal pressure occurs inside the battery, preventing the battery from exploding and causing damage to external objects.

[0048] The working principle and usage process of this invention are as follows: During use, a cylindrical aluminum shell 1 containing the battery cell can be installed inside the battery compartment to supply power to external devices. During power supply, the first conductive electrode post 4 is also connected to the electrode plate inside the battery compartment. Additionally, the elastic force of the spring 903 effectively connects the second conductive electrode post 902 to another electrode plate inside the battery compartment, maintaining stable power supply. When not in use, the second conductive electrode post 902 can be pressed to move towards the base 901. Then, the ring cylinder 905 engages with the threaded groove 909 of the base 901, shortening the overall length of the battery. Even when the battery is placed inside the battery compartment, the battery... One end cannot be connected to the electrode plate of the device, thereby reducing the discharge of the battery to external devices during long-term storage. During the transportation of aluminum shell 1, the cavity 6 formed between the outer surface of aluminum shell 1 and the first protective cover 2 and the second protective cover 3 and the rubber block 16 facilitate the avoidance of direct collision between aluminum shell 1 and external objects. The cavity 6 and the rubber block 16 provide an elastic ring to improve the safety of aluminum shell 1. Furthermore, in the event of a malfunction and deflagration of aluminum shell 1, the bauxite layer 14 and the aluminum foil layer 15 can isolate the flame of aluminum shell 1 from the outside to reduce external damage. Moreover, the first protective cover 2 and the second protective cover 3 are easy to disassemble and assemble, which improves the practicality of the device.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
