Detailed Description

For the purpose of making the purpose, technical solutions and advantages of the present disclosure more apparent, the present disclosure will be described in further detail below with reference to the accompanying drawings and detailed description. It should be understood that the detailed description and specific examples, while indicating the scope of the disclosure, are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein in the description of the disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure.

The column type battery, especially the cylindrical battery has the characteristics of better monomer consistency, good monomer mechanical property and the like. Moreover, compared with a square battery or a soft package battery, the cylindrical battery has higher bending strength on one hand; on the other hand, the energy of the monomer is small, and the control is easy when an accident occurs. Therefore, the cylindrical battery is often used as a power supply source for some electronic devices (e.g., notebook computers, remote controllers, unmanned aerial vehicles, etc.) and new energy vehicles.

However, in the conventional cylindrical battery, the battery core is sealed in the cylinder by welding, and the packaging method of the battery can well maintain the stability of the internal environment of the cylindrical battery. But also means that the process of disassembling the column type battery for maintenance is abnormally difficult once the inside of the column type battery is broken down, and the maintenance cost is even higher than the self cost of the column type battery. Therefore, once the inside of the column battery fails, the post-service battery is discarded directly and then replaced with a new battery.

In recent years, with the rapid depletion of raw materials of lithium batteries worldwide, the production cost of the batteries is higher and higher, and how to realize the maintenance and the recycling of the column-type batteries and reduce the after-sale cost of electronic equipment or automobiles is a problem which needs to be solved urgently by the industry.

Based on this, the present disclosure provides a column type battery that can realize quick assembly and disassembly to make maintenance and reuse convenient, so that the after-sales cost of a device to which the column type battery is applied can be effectively reduced.

For a better understanding of the present disclosure, an automobile provided with the foregoing pillar type battery will be described below with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a partial exploded view of an automobile according to an embodiment, and the present disclosure provides an automobile 1 including an automobile body 10 and a pillar type battery 20, wherein the automobile body 10 is provided with a battery compartment 11 for mounting the pillar type battery 20. Since the pillar type battery 20 provided to the automobile 1 can be quickly attached and detached for maintenance and recycling. Therefore, when a certain column type battery 20 on the automobile 1 is out of order, the out-of-order column type battery 20 can be quickly repaired for reuse, rather than being directly discarded and replaced with a new battery, which is advantageous for reducing the after-sales cost of the automobile 1.

Similarly, the pillar-type battery 20 can also be applied to an electronic device to reduce the after-sales cost of the electronic device, and will not be described herein again.

Referring to fig. 2 to 4, fig. 2 is a schematic structural view of the pillar-type battery shown in fig. 1, fig. 3 is an exploded schematic structural view of the pillar-type battery shown in fig. 2, and fig. 4 is a sectional view of the center a-a of the pillar-type battery shown in fig. 2. The cylindrical battery 20 comprises a cylinder 21 made of conductive material, a mounting part 22, a conductive part 23 and a battery core 30; the cylinder 21 made of conductive material comprises an accommodating cavity 211 and an opening 212 communicated with the accommodating cavity 211; the conductive element 23 is insulated from the barrel 21, the conductive element 23 is detachably arranged on the barrel 21 through the mounting element 22, and the conductive element 23 and the mounting element 22 cooperate to seal the opening 212; the battery cell 30 is arranged in the accommodating cavity 211, the battery cell 30 comprises a first conductor 31 and a second conductor 32, the first conductor 31 is electrically connected with the conductive piece 23, and the second conductor 32 is electrically connected with the barrel 21; at least one of the mounting member 22 and the conductive member 23 is provided with a mounting portion 40, so that the conductive member 23 is mounted on and dismounted from the barrel 21 by the mounting portion 40. Since the mounting member 22 and the conductive member 23 are provided with the mounting portion 40. Thus, when the inside of the cylindrical battery 20 malfunctions, the conductive member 23 can be disassembled from the cylindrical body 21 by the disassembling part 40 to perform maintenance of the battery through the opening 212. When the maintenance of the cylindrical battery 20 is completed, the conductive member 23 is assembled to the cylindrical body 21 by the assembling portion 40, and the assembling member 22 and the conductive member 23 are engaged to seal the opening 212. Thus, the column-type battery 20 can be quickly disassembled and assembled, and the column-type battery 20 can be conveniently maintained and reused. It is understood that the conductive member 23 may be used as an electrode of the pillar type battery 20 for supplying power to an external electric device, such as a common positive pillar. The first and second electrical conductors 31 and 32 may include, but are not limited to, tabs 311 of the battery cell 30, and the first and second electrical conductors 31 and 32 function to connect the battery cell 30 to exposed positive and negative electrodes in the battery case, which is not limited herein.

Specifically, the second electrical conductor 32 may be electrically connected to the inner side of the barrel 21, such as shown in fig. 4. Therefore, compared with the current technical scheme of electrically connecting the negative electrode of the battery cell 30 with the bottom of the barrel 21, the embodiment can realize the electrical connection between the battery cell 30 and the barrel 21 without forming an opening at the bottom of the barrel 21, simplify the structure of the cylindrical battery 20, and facilitate the improvement of the manufacturing efficiency of the cylindrical battery 20.

Further, in some embodiments, the second electrical conductor 32 may be a metal sheet having elasticity. So, when placing electric core 30 in the chamber 211 that holds of barrel 21, the inner wall of barrel 21 can be laminated automatically to second electric conductor 32 under the effect of elastic force, need not to adopt welding process alright realize the electricity of second electric conductor 32 with barrel 21, has simplified the assembly process of post type battery 20.

Specifically, the manner of electrically connecting the conductive member 23 and the first conductive member 31 may include, but is not limited to: by means of fastening, such as welding, by means of an articulated connection, etc. For example:

referring to fig. 4, fig. 4 is a sectional view of the cylindrical battery shown in fig. 2 taken along the center a-a, in some embodiments, the first conductive member 31 is fixedly connected to the conductive member 23, and the length of the first conductive member 31 is adjustable, so that the conductive member 23 can be separated from the cylindrical body 21. Because the length of the first conductor 31 is adjustable, when the conductive member 23 is detached from the barrel 21, the first conductor 31 can extend along with the movement of the conductive member 23, which is beneficial to avoiding the damage of the fixed connection between the first conductor 31 and the conductive member 23 when the conductive member 23 is detached.

Further, with continued reference to fig. 4, in order to make the first conductive body 31 stretch out better with the detachment of the conductive member 23, in other embodiments, at least a portion of the first conductive body 31 is spiral or bent. Since the spiral or bent structure has a certain deformation capability, when the conductive member 23 is mounted on the cylindrical body 21 after the conductive member 23 is fixedly connected to the first conductive member 31, the spiral or bent first conductive member 31 can be compressed in the accommodating cavity 211 of the cylindrical body 21 by the compression force. When the conductive member 23 needs to be detached from the cylinder 21, the length of the first conductive member 31 in a spiral or bent shape can be changed along with the movement of the conductive member 23, which is beneficial to preventing the fixed connection between the two from being damaged due to pulling or twisting.

Alternatively, referring to fig. 5, fig. 5 is a central cross-sectional view of a pillar-type battery shown in another embodiment. The first conductor 31 includes a tab 311 electrically connected to the battery cell 30 and a conductive wire 312 fixedly connected to the tab 311, the conductive wire 312 is fixedly connected to the conductive member 23, and at least a portion of the conductive wire 312 is formed in a spiral shape or a bent shape. Since the conductive wire 312 is relatively flexible, it can be well crimped inside the cylinder 21, and the conductive wire 312 is also relatively inexpensive. Therefore, the attachment/detachment work of the column battery 20 is facilitated, and the cost of the column battery 20 can be further reduced.

Still alternatively, referring to fig. 6, fig. 6 is a central sectional view of a pillar type battery shown in another embodiment. Since when the mounting member 22 or the conductive member 23 is detachably mounted on the barrel 21 by screwing, if the conductive member 23 is fixedly connected to the battery cell 30, the connection between the conductive member 23 and the battery cell 30 is easily damaged by being twisted during the rotation of the mounting member 22 or the conductive member 23 compared to the barrel 21. Therefore, in some other embodiments, in order to detach the conductive member 23 from the cylinder 21 without any fear that the connection between the conductive member 23 and the first conductive member 31 will be damaged, the first conductive member 31 includes a conductive ferrule 313. The conductive ferrule 313 is an annular body structure, and the conductive ferrule 313 is placed in the accommodating cavity 211 of the cylinder 21. One end of the conductive member 23 is detachably inserted into the inner ring of the conductive ferrule 313, and the conductive member 23 is in contact with the surface of the conductive ferrule 313 to achieve electrical connection. Meanwhile, the conductive ferrule 313 is electrically connected with the battery cell 30 in a fixed manner, and the conductive ferrule 313 does not rotate relative to the inner wall of the barrel 21. Thus, when the conductive member 23 needs to be rotatably detached from the cylinder 21, the conductive ring 313 cannot rotate relative to the cylinder 21 because the conductive member 23 can rotate and linearly move relative to the conductive ring 313. During the process of disassembling the conductive member 23, the conductive ferrule 313 does not generate a rotational movement and is not pulled unlimitedly along with the movement of the conductive member 23. Therefore, in the process of disassembling the conductive piece 23, the joint between the conductive piece 23 and the battery core 30 is not damaged, so that the whole disassembling process is smoother. When the conductive member 23 is mounted on the barrel 21 after the maintenance of the cylindrical battery 20 is completed, the conductive member 23 is automatically inserted into the conductive collar 313 to automatically achieve the electrical connection with the battery core 30.

It should be noted that the conductive ferrule 313 may not rotate relative to the inner wall of the cylinder 21, and the conductive ferrule 313 may be in interference fit with the cylinder 21; or the conductive ferrule 313 and the cylinder 21 are matched through a spline structure, that is, one of the conductive ferrule 313 and the cylinder 21 is provided with spline teeth, and the other is provided with spline grooves, so that the conductive ferrule 313 is prevented from rotating relative to the cylinder 21 through the matching of the spline teeth and the spline grooves.

Still alternatively, referring to fig. 7, fig. 7 is a central cross-sectional view of a cylindrical battery shown in another embodiment, in yet another embodiment, the first conductor 31 is an elastic member with conductive performance, such as a compression spring made of metal, one end of the elastic member is electrically connected to the conductive member 23, and the other end of the elastic member is electrically connected to the battery cell 30. Because the elastic part has certain elastic deformation capacity, the elastic part is taken as the first conductor 31, so that the first conductor 31 can be conveniently adjusted in length, and the battery can be more conveniently disassembled and assembled. Because the elastic member is automatically compressed when the conductive member 23 is mounted to the cylinder 21, and automatically extended when the conductive member 23 is removed from the cylinder 21 so that the conductive member 23 can be smoothly separated from the cylinder 21.

Specifically, the elastic element may be electrically connected to the conductive element 23 and the battery cell 30 in a manner that the conductive element 23 is fixedly connected to the elastic element, and the battery cell 30 abuts against the elastic element; or the conductive piece 23 abuts against the elastic piece, and the battery cell 30 is fixedly connected with the elastic piece; or, the conductive member 23 and the battery cell 30 may be fixedly connected or abutted to the elastic member, and this is not limited in this respect.

For example, in one embodiment, one end of the elastic member is fixedly connected to the battery cell 30, and the other end of the elastic member is electrically connected to the conductive member 23 by abutting against the conductive member. Because the elastic element is connected with the conductive element 23 in an abutting manner, when the conductive element 23 is detached from the barrel 21, the electric connection relationship between the conductive element 23 and the battery cell 30 is not damaged, because the electric connection relationship between the conductive element 23 and the battery cell 30 is automatically disconnected when the conductive element 23 is detached, but the electric connection relationship between the conductive element 23 and the battery cell 30 is restored when the conductive element 23 is installed, and the disassembly and assembly operation of the cylindrical battery 20 is more convenient. And because the compressed elastic element has a tendency of recovering, after the conductive element 23 is mounted on the cylinder 21, the first conductive body 31 can effectively maintain the electrical connection relationship with the conductive element 23 and the battery cell 30, and the occurrence of poor circuit contact is avoided.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a cylindrical battery shown in an embodiment, in order to reduce the number of parts to be disassembled during the disassembling and assembling process of the cylindrical battery 20, so as to improve the disassembling efficiency. In some embodiments, the conductive member 23 is fixedly connected to the mounting member 22 and insulated from each other, and the mounting member 22 is detachably connected to the cylinder 21.

Illustratively, referring to fig. 3 and 4, fig. 3 is an exploded view of the structure of the pillar-type battery shown in fig. 2, and fig. 4 is a sectional view of the center a-a of the pillar-type battery shown in fig. 2. In an embodiment, the conductive member 23 is fixedly disposed on the mounting member 22 and insulated from the mounting member 22, the mounting member 22 is provided with an external thread 221, and the opening 212 of the barrel 21 is provided with an internal thread 213 threadedly engaged with the external thread 221. The threaded connection facilitates both the removal and installation of the mounting member 22 and the sealing of the opening 212, as well as providing some sealing action.

Specifically, in an embodiment, the mounting member 22 is provided with a mounting hole 222, and the conductive member 23 is embedded in the mounting member 22 through the mounting hole 222, so as to fix the conductive member 23 to the mounting member 22, as shown in fig. 5. Because, the mounting hole 222 can play a certain role in positioning and fixing the conductive member 23. Therefore, the technical solution of providing the mounting hole 222 on the mounting member 22 and embedding the conductive member 23 in the mounting hole 222 can make the conductive member 23 more stable.

Further, with reference to fig. 3 and 4, in another embodiment, the material of the cylinder 21 and the material of the mounting member 22 are both metal materials, and the pillar battery 20 further includes a sealing sleeve 50 made of an insulating material, wherein the sealing sleeve 50 is disposed in the mounting hole 222 and clamped between the mounting member 22 and the conductive member 23. Since the metal material has good ductility and pressure resistance, the material of the cylindrical body 21 and the mounting member 22 is selected from metal, which is advantageous for improving the structural stability of the cylindrical battery 20. Meanwhile, the existence of the sealing sleeve 50 not only realizes insulation between the conductive member 23 and the barrel 21, but also plays a role in sealing, thereby being beneficial to improving the sealing performance of the column-type battery 20, ensuring the environmental stability inside the column-type battery 20 and further improving the safety and reliability of the column-type battery 20.

Referring to fig. 4, fig. 4 is a central sectional view of the pillar-shaped battery shown in fig. 2, in order to facilitate a user to distinguish the positive electrode and the negative electrode of the battery during the use of the battery, in an embodiment, at least a portion of the conductive member 23 is exposed and protrudes out of the mounting hole 222. Therefore, the conductive member 23 can be controlled to protrude from the surface of the mounting member 22, so that the user can quickly identify the positive and negative electrodes of the battery.

Referring to fig. 5, fig. 5 is a central cross-sectional view of a cylindrical battery in another embodiment, in which the conductive member 23 needs to have both conductive performance and insulation from the cylindrical body 21. Therefore, in some embodiments, in order to simplify the number of components of the cylindrical battery 20 and reduce the production cost of the cylindrical battery 20, the mounting member 22 is made of an insulating material, for example, the mounting member 22 may be made of plastic or ceramic, and the conductive member 23 is embedded in the mounting member 22. Therefore, the conductive piece 23 and the cylinder 21 can be insulated without additionally arranging an insulating piece, the assembly process of the cylindrical battery 20 is simplified, and the production cost of the cylindrical battery 20 is reduced.

Of course, it is understood that in other embodiments, the mounting member 22 may also be made of an insulating material, for example, the mounting member 22 may be made of plastic or ceramic, the mounting member 22 is fixedly connected to the barrel 21, the conductive member 23 is detachably connected to the mounting member 22, and the detachable portion is disposed on the conductive member 23, as shown in fig. 8, for example. As such, when assembling the battery 20, the mounting member 22 need not be assembled; when the conductive member 23 needs to be detached from the cylindrical body 21, the mounting member 22 does not need to be detached, the number of parts to be assembled and disassembled in the cylindrical battery 20 is reduced, and the improvement of the disassembling and assembling efficiency is facilitated.

Referring to fig. 8, fig. 8 is a central cross-sectional view of a pillar type battery in yet another embodiment, in one embodiment, the barrel 21 includes a bottom portion disposed opposite to the opening 212, the pillar type battery 20 further includes a buffer 60 having an insulating property, the buffer 60 is disposed at the bottom portion, and the battery cell 30 is disposed on the buffer 60. Since the buffer pad 60 has a certain buffering performance, the battery cell 30 is disposed on the buffer pad 60, which is beneficial to preventing the battery cell 30 from being damaged when the battery is vibrated.

Referring to fig. 2 to 4, fig. 2 is a schematic structural view of a pillar type battery according to an embodiment, fig. 3 is an exploded schematic structural view of the pillar type battery shown in fig. 2, and fig. 4 is a sectional view of the center a-a of the pillar type battery shown in fig. 2. In order to facilitate the process of attaching and detaching the battery, the detaching part 40 includes at least one recess structure provided on the mounting member 22. When the battery needs to be disassembled and assembled, the battery can be disassembled and assembled quickly only by inserting the shaft-shaped object into the recess and rotating the mounting part 22 relative to the barrel 21 without using other special tools.

For example, in some embodiments, the detachable portion 40 is two holes, and the two holes are symmetrically disposed on the outer side surface of the mounting member 22. Specifically, the hole may be a circular hole or a polygonal hole, which is not particularly limited herein.

Of course, the detachable portion 40 may also be disposed on the conductive member 23, such as shown in fig. 8, and is not limited herein.

Still alternatively, the detachable portion 40 can have other configurations, such as, in some embodiments, the detachable portion 40 includes at least one raised feature disposed on the mounting member 22. Thus, the convex structure can be used as a force application point, so that when the dismounting part is of the convex structure, the dismounting of the battery can be completed by bare hands without adopting tools.

In the present disclosure, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integral; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present disclosure can be understood by those of ordinary skill in the art as appropriate.

In the present disclosure, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

It will be understood that when an element is referred to as being "secured to," "disposed on," "secured to," or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. Further, when one element is regarded as being fixedly connected with the other element in a transmission manner, the two elements can be detachably connected and also can be fixed in an undetachable manner, power transmission can be achieved, such as sleeving, clamping, integrally-formed fixing, welding and the like, and the traditional technology can achieve the purpose of no encumbrance. When an element is perpendicular or nearly perpendicular to another element, it is desirable that the two elements are perpendicular, but some vertical error may exist due to manufacturing and assembly effects. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only show several embodiments of the present disclosure, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the inventive concept of the present disclosure, which falls within the scope of the present disclosure.
