Description

Technical Field

[0001] This disclosure relates to the technical field of removable cylindrical pouch batteries, and in particular to a fixed support structure and a removable cylindrical pouch battery. Background Technology

[0002] Cylindrical pouch batteries are small in size and are generally used in small electrical devices, such as remote controls and smart handheld devices. However, most cylindrical pouch batteries on the market are fixed in the battery compartment of the device by welding. This makes the installation or removal of cylindrical pouch batteries time-consuming and laborious, and may also damage the battery or device due to improper operation. This greatly increases the difficulty of installing and removing cylindrical pouch batteries, thus greatly reducing the convenience of using pouch cylindrical batteries.

[0003] To address the aforementioned technical challenges, some manufacturers have conducted further research and development. For example, an existing quick-assembly pouch cylindrical battery discloses a battery cell and two injection-molded parts located at opposite ends of the cell. The battery cell has two electrode tabs, which are exposed to the outside through the injection-molded parts. This pouch cylindrical battery can be directly connected to the customer's flexible terminal via the injection-molded parts, reducing the need for wire connections and achieving rapid assembly. This significantly reduces the difficulty of installing and disassembling the pouch cylindrical battery, thereby greatly improving its ease of use.

[0004] However, the aforementioned pouch cylindrical battery relies on the elastic properties of the client's flexible terminals to maintain its position within the battery compartment. This results in poor installation reliability, making the pouch cylindrical battery prone to loosening or displacement when subjected to external vibrations or impacts. This significantly increases the likelihood of poor contact between the pouch cylindrical battery and the client's flexible terminals. Furthermore, the elastic properties of the client's flexible terminals gradually decrease when under prolonged compression, further reducing the installation reliability of the pouch cylindrical battery. Consequently, this greatly diminishes the installation reliability and operational stability of the pouch cylindrical battery. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a fixed bracket structure and a detachable cylindrical soft-pack battery that not only have better ease of use, but also better installation reliability and usage stability.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A fixing bracket structure is provided for mounting and fixing the cylindrical soft-pack battery cells of a detachable cylindrical soft-pack battery. The fixing bracket structure has a cell mounting area for mounting and fixing the cylindrical soft-pack battery cells. A snap-fit ​​groove is formed on the side of the fixing bracket structure opposite to the cell mounting area. The snap-fit ​​groove is adapted to fit with the snap-fit ​​flange of the battery compartment of the electrical device, so that the fixing bracket is snapped and fixed in the battery compartment through the snap-fit ​​groove.

[0008] In one embodiment, the fixed support structure is a one-time injection molded structure.

[0009] In one embodiment, the fixed bracket structure includes a cell fixing component and a snap-fit ​​component. The cell mounting area is formed on the cell fixing component. The cell fixing component is fixedly connected to the snap-fit ​​component. The snap-fit ​​groove is formed on one side of the snap-fit ​​component opposite to the cell fixing component. The fixed bracket structure is snapped and fixed in the battery compartment by the snap-fit ​​component.

[0010] In one embodiment, the cell fixing member and the snap-fit ​​member are integrally formed.

[0011] In one embodiment, the cell fixing component includes a first fixing part, a second fixing part, and a connecting part. The first fixing part and the second fixing part are respectively fixed to both ends of the connecting part. The first fixing part and the second fixing part are arranged at a distance from each other so that the first fixing part, the second fixing part, and the connecting part together define the cell mounting area. The first fixing part and the second fixing part are respectively used to fix and connect to both ends of the cylindrical soft-pack cell.

[0012] In one embodiment, the snap-fit ​​element further has a clearance opening communicating with the snap-fit ​​groove, the clearance opening being adapted to fit with the snap-fit ​​flange of the battery compartment.

[0013] In one embodiment, the bottom of the snap-fit ​​groove is further formed with a limiting groove that communicates with the snap-fit ​​groove, the limiting groove being adapted to the snap-fit ​​flange of the battery compartment.

[0014] In one embodiment, the first fixing part, the second fixing part, and the connecting part are integrally formed.

[0015] In one embodiment, the fixed bracket structure has a disassembly groove formed at one end adjacent to the snap-fit ​​slot.

[0016] In one embodiment, a first stepped flange is formed on one side of the first fixing part adjacent to the cell mounting area. The first stepped flange is used to fix the cylindrical soft-pack battery cell. A second stepped flange is formed on one side of the second fixing part adjacent to the cell mounting area. The second stepped flange is used to fix the cylindrical soft-pack battery cell to the cell mounting area.

[0017] A detachable cylindrical pouch battery includes a cylindrical pouch cell and a fixing bracket structure as described in any of the above embodiments, wherein the cylindrical pouch cell is mounted and fixed in the cell mounting area of ​​the fixing bracket structure.

[0018] In one embodiment, the fixing bracket structure is injection molded and fixed to the cylindrical soft-pack battery cell.

[0019] In one embodiment, the detachable cylindrical pouch battery further includes a control circuit board, which is mounted and fixed to the end of the fixing bracket structure away from the snap-fit ​​groove. The end of the fixing bracket structure away from the snap-fit ​​groove has a connection port that communicates with the cell mounting area. The conductive end of the cylindrical pouch cell passes through the connection port and is electrically connected to the control circuit board.

[0020] Compared with the prior art, this disclosure has at least the following advantages:

[0021] 1. The aforementioned fixed support structure, by forming a cell mounting area, is used to install and fix cylindrical soft-pack cells to support and protect them. This not only improves the structural strength of the cylindrical soft-pack cells but also effectively prevents the cylindrical soft-pack cells from being squeezed or collided with the inner wall of the battery compartment of the electrical device during the installation or removal of the removable cylindrical soft-pack battery. This greatly reduces the possibility of damage or even destruction of the cylindrical soft-pack cells, thereby significantly improving the service life and stability of the removable cylindrical soft-pack battery.

[0022] 2. Because the fixed bracket structure has a snap-fit ​​groove on the side away from the cell mounting area, the snap-fit ​​groove is adapted to match the snap-fit ​​flange of the battery compartment of the electrical device, so that the fixed bracket is snapped and fixed in the battery compartment through the snap-fit ​​groove. Compared with the method of quick-assembly soft-pack cylindrical batteries in the above-mentioned related technologies, which are held in place in the battery compartment by elastic terminals, the method of snapping and fixing the detachable cylindrical soft-pack battery in the battery compartment of the electrical device through the snap-fit ​​groove in this application not only makes the detachable cylindrical soft-pack battery more securely placed in the battery compartment, but also makes the detachable cylindrical soft-pack battery more securely placed in the battery compartment. The possibility of loosening or displacement of the removable cylindrical pouch battery when subjected to external vibration or impact is greatly reduced. Furthermore, it ensures that the removable cylindrical pouch battery remains securely contained within the battery compartment during prolonged use, further reducing the likelihood of loosening or displacement. This significantly reduces the possibility of poor contact between the conductive ends of the removable cylindrical pouch battery and the conductive ends of the battery compartment, thereby greatly improving the installation reliability and operational stability of the removable cylindrical pouch battery.

However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0031] Unless otherwise defined, 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 is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0033] like Figures 1 to 5 As shown, in one embodiment, a fixing bracket structure 100 is used to install and fix the cylindrical soft-pack cells 200 of the removable cylindrical soft-pack battery 10. The fixing bracket structure 100 forms a cell mounting area 110, which is used to install and fix the cylindrical soft-pack cells 200 to support and protect the cylindrical soft-pack cells 200. This not only improves the structural strength of the cylindrical soft-pack cells 200, but also effectively avoids the cylindrical soft-pack cells 200 from being squeezed or collided with the inner wall of the battery compartment of the electrical device during the installation or removal process. This greatly reduces the possibility of damage or even destruction of the cylindrical soft-pack cells 200, thereby greatly improving the service life and stability of the removable cylindrical soft-pack battery 10.

[0034] like Figures 1 to 5As shown, furthermore, a snap-fit ​​groove 120 is formed on the side of the fixed bracket structure 100 opposite to the cell mounting area 110. The snap-fit ​​groove 120 is adapted to fit with the snap-fit ​​flange of the battery compartment of the electrical device, so that the fixed bracket is snapped and fixed in the battery compartment through the snap-fit ​​groove 120. Compared with the method of quick-assembly soft-pack cylindrical batteries in the above-mentioned related technologies, which are held in place in the battery compartment by elastic pressure of elastic terminals, the method of snapping and fixing the detachable cylindrical soft-pack battery 10 in the battery compartment of the electrical device through the snap-fit ​​groove 120 not only makes the detachable cylindrical soft-pack battery 10 more securely held in the battery compartment. This design significantly reduces the likelihood of the removable cylindrical pouch battery 10 becoming loose or displaced when subjected to external vibrations or impacts. Furthermore, it ensures that the removable cylindrical pouch battery 10 remains securely contained within the battery compartment during extended use, further reducing the possibility of loosening or displacement. This also greatly reduces the likelihood of poor contact between the conductive ends of the removable cylindrical pouch battery 10 and the conductive ends of the battery compartment, thereby significantly improving the installation reliability and operational stability of the removable cylindrical pouch battery 10.

[0035] The aforementioned fixed support structure 100, having a cell mounting area 110 for mounting and fixing cylindrical soft-pack cells 200, provides support and protection for the cylindrical soft-pack cells 200. This not only improves the structural strength of the cylindrical soft-pack cells 200 but also effectively prevents the cylindrical soft-pack cells 200 from being squeezed or collided with the inner wall of the battery compartment of the electrical device during the installation or removal process. This greatly reduces the possibility of damage or even destruction to the cylindrical soft-pack cells 200, thereby significantly improving the service life and stability of the removable cylindrical soft-pack battery 10.

[0036] Furthermore, since the fixed bracket structure 100 has a snap-fit ​​groove 120 formed on the side opposite to the cell mounting area 110, the snap-fit ​​groove 120 is adapted to fit the snap-fit ​​flange of the battery compartment of the electrical device, so that the fixed bracket is snapped and fixed in the battery compartment through the snap-fit ​​groove 120. Compared with the method of quick-assembly soft-pack cylindrical batteries in the above-mentioned related technologies, which are held and limited in the battery compartment by elastic terminals, the method of snapping and fixing the detachable cylindrical soft-pack battery 10 in the battery compartment of the electrical device through the snap-fit ​​groove 120 not only makes the detachable cylindrical soft-pack battery 10 more securely limited in the battery compartment, This significantly reduces the likelihood of the removable cylindrical pouch battery 10 loosening or shifting when subjected to external vibrations or impacts. Furthermore, it ensures that the removable cylindrical pouch battery 10 remains securely contained within the battery compartment during prolonged use, further reducing the possibility of loosening or shifting. This also greatly reduces the likelihood of poor contact between the conductive ends of the removable cylindrical pouch battery 10 and the conductive ends of the battery compartment, thereby significantly improving the installation reliability and operational stability of the removable cylindrical pouch battery 10.

[0037] like Figures 1 to 3 As shown, in one embodiment, the fixing bracket structure 100 is a one-time injection molded structure, so that the fixing bracket structure 100 can be injection molded according to the shape and size of the battery compartment. This allows the cylindrical soft-pack battery cell 200 to be adapted to the battery compartments of different electrical devices through the fixing bracket, thereby greatly improving the applicability of the removable cylindrical soft-pack battery 10. At the same time, manufacturing the fixing bracket structure 100 by injection molding can effectively reduce the steps of the removable cylindrical soft-pack battery 10, thereby reducing the production difficulty of the removable cylindrical soft-pack battery 10 and greatly improving the production efficiency of the removable cylindrical soft-pack battery 10.

[0038] like Figures 1 to 4 As shown, in one embodiment, the fixing bracket structure 100 includes a cell fixing member 130 and a snap-fit ​​member 140. A cell mounting area 110 is formed on the cell fixing member 130. The cell fixing member 130 is fixedly connected to the snap-fit ​​member 140. A snap-fit ​​groove 120 is formed on one side of the snap-fit ​​member 140 away from the cell fixing member 130. The fixing bracket structure 100 is snapped and fixed in the battery compartment by the snap-fit ​​member 140, so that the cell fixing member 130 can be reliably snapped and fixed in the battery compartment by the snap-fit ​​member 140, so that the removable cylindrical soft-pack battery 10 can be reliably confined in the battery compartment, thereby greatly improving the stability of the removable cylindrical soft-pack battery 10 in use.

[0039] like Figures 1 to 4As shown, in one embodiment, the cell fixing member 130 and the snap-fit ​​member 140 are integrally formed to improve the structural compactness of the fixing bracket structure 100.

[0040] like Figures 1 to 4 As shown, in one embodiment, the cell fixing member 130 includes a first fixing part 131, a second fixing part 132, and a connecting part 133. The first fixing part 131 and the second fixing part 132 are respectively fixed to both ends of the connecting part 133. The first fixing part 131 and the second fixing part 132 are arranged at a distance from each other so that the first fixing part, the second fixing part 132, and the connecting part 133 together define the cell mounting area 110. The first fixing part 131 and the second fixing part 132 are respectively used to fix and connect the two ends of the cylindrical soft-pack cell 200 so that the cylindrical soft-pack cell 200 can be reliably fixed on the cell fixing member 130. This allows the cylindrical soft-pack cell 200 to be reliably confined in the battery compartment by the fixing bracket structure 100, thereby greatly improving the stability of the removable cylindrical soft-pack battery 10. At the same time, it can also increase the contact area between the cylindrical soft-pack cell 200 and the air, thereby improving the heat dissipation effect of the removable cylindrical soft-pack battery 10.

[0041] like Figures 3 to 4 As shown, in one embodiment, the snap-fit ​​member 140 also has a clearance opening 141 communicating with the snap-fit ​​groove 120. The clearance opening 141 is adapted to the snap-fit ​​flange of the battery compartment so that the snap-fit ​​flange can be quickly snapped into the snap-fit ​​groove 120 through the clearance opening 141. This greatly reduces the difficulty of snapping and fixing the snap-fit ​​member 140 to the snap-fit ​​flange, and greatly reduces the installation difficulty of the removable cylindrical soft-pack battery 10. At the same time, the snap-fit ​​member 140 can also be quickly separated from the snap-fit ​​flange through the clearance opening 141, which greatly reduces the disassembly difficulty of the removable cylindrical soft-pack battery 10, and thus greatly reduces the replacement difficulty of the removable cylindrical soft-pack battery 10, thereby improving the ease of use of the removable cylindrical soft-pack battery 10.

[0042] like Figures 3 to 4 As shown, in one embodiment, the bottom of the snap-fit ​​groove 120 is further formed with a limiting groove 121 that communicates with the snap-fit ​​groove 120. The limiting groove 121 is used to be adapted to the snap-fit ​​flange of the battery compartment so that when the snap-fit ​​flange is snapped into the snap-fit ​​groove 120, the snap-fit ​​flange can be snapped and limited in the limiting groove 121, so that the fixed bracket structure 100 can be more securely limited in the battery compartment. This further reduces the possibility of the detachable cylindrical soft-pack battery 10 loosening or shifting when subjected to external vibration or impact. As a result, the possibility of poor contact between the conductive end of the detachable cylindrical soft-pack battery 10 and the conductive end of the battery compartment is greatly reduced, thereby greatly improving the installation reliability and usage stability of the detachable cylindrical soft-pack battery 10.

[0043] like Figures 3 to 4 As shown, in one embodiment, the first fixing part 131, the second fixing part 132 and the connecting part 133 are integrally formed to improve the structural compactness of the battery cell fixing member 130.

[0044] like Figures 3 to 4 As shown, in one embodiment, a disassembly groove 142 is formed at one end of the fixed bracket structure 100 adjacent to the snap-fit ​​groove 120. When it is necessary to remove the removable cylindrical soft-pack battery 10 from the battery compartment, the production personnel can obtain an additional force application point through the disassembly groove 142. At the same time, the contact area between the finger and the fixed bracket structure 100 is effectively increased, which greatly increases the friction between the finger and the fixed bracket structure 100, thereby greatly reducing the difficulty of disassembling the removable cylindrical soft-pack battery 10 and further improving the ease of use of the removable cylindrical soft-pack battery 10.

[0045] like Figures 1 to 4 As shown, in one embodiment, a first stepped flange 1311 is formed on one side of the first fixing part 131 adjacent to the cell mounting area 110. The first stepped flange 1311 is used to fix and connect with the cylindrical soft-pack cell 200. A second stepped flange 1321 is formed on one side of the second fixing part 132 adjacent to the cell mounting area 110. The second stepped flange 1321 is used to fix and connect with the cylindrical soft-pack cell 200, so that the cylindrical soft-pack cell 200 is installed and fixed in the cell mounting area 110. The first stepped flange 1311 can effectively increase the thickness of the first fixing part 131, and the second stepped flange 1321 can also effectively increase the thickness of the second fixing part 132, so that the structural strength of the first fixing part 131 and the second fixing part 132 is greatly improved, thereby greatly improving the structural strength of the fixing bracket structure 100, and thus greatly improving the stability and service life of the detachable cylindrical soft-pack battery 10.

[0046] This disclosure also provides a detachable cylindrical pouch battery 10, including a cylindrical pouch cell 200 and a fixing bracket structure 100 as described in any of the above embodiments, wherein the cylindrical pouch cell 200 is mounted and fixed to the cell mounting area 110 of the fixing bracket structure 100.

[0047] like Figures 1 to 2As shown, in one embodiment, the fixing bracket structure 100 is injection molded and fixed to the cylindrical soft-pack battery cell 200. This not only greatly reduces the difficulty of installing and fixing the cylindrical soft-pack battery cell 200 to the fixing bracket structure 100, but also ensures that the cylindrical soft-pack battery cell 200 is securely fixed to the fixing bracket structure 100. This allows the cylindrical soft-pack battery cell 200 to be securely confined within the battery cell installation area 110, thereby greatly reducing the production difficulty of the removable cylindrical soft-pack battery 10 and also greatly improving the stability of the removable cylindrical soft-pack battery 10 in use.

[0048] like Figures 1 to 2 As shown, in one embodiment, the removable cylindrical pouch battery 10 further includes a control circuit board 300. The control circuit board 300 is mounted and fixed to the end of the fixing bracket structure 100 away from the snap-fit ​​groove 120. The end of the fixing bracket structure 100 away from the snap-fit ​​groove 120 forms a connection port (not shown) that communicates with the cell mounting area 110. The conductive end of the cylindrical pouch cell 200 passes through the connection port and is electrically connected to the control circuit board 300, so that the removable cylindrical pouch battery 10 can detect and control the voltage and current of the cylindrical pouch cell 200 in real time through the control circuit board 300, thereby greatly improving the stability and safety of the removable cylindrical pouch battery 10.

[0049] Compared with the prior art, this disclosure has at least the following advantages:

[0050] 1. The aforementioned detachable cylindrical pouch battery 10, due to the fixed bracket structure 100 forming a cell mounting area 110, is used to install and fix the cylindrical pouch cell 200 to support and protect the cylindrical pouch cell 200. This not only improves the structural strength of the cylindrical pouch cell 200, but also effectively avoids the cylindrical pouch cell 200 from being squeezed or collided with the inner wall of the battery compartment of the electrical device during the installation or removal process. This greatly reduces the possibility of damage or even destruction of the cylindrical pouch cell 200, thereby greatly improving the service life and stability of the detachable cylindrical pouch battery 10.

[0051] 2. Because the fixed bracket structure 100 has a snap-fit ​​groove 120 formed on the side opposite to the cell mounting area 110, the snap-fit ​​groove 120 is adapted to match the snap-fit ​​flange of the battery compartment of the electrical device, so that the fixed bracket is snapped and fixed in the battery compartment through the snap-fit ​​groove 120. Compared with the method of quick-assembly soft-pack cylindrical batteries in the above-mentioned related technologies, which are held and limited in the battery compartment by elastic terminals, the method of snapping and fixing the detachable cylindrical soft-pack battery 10 in the battery compartment of the electrical device through the snap-fit ​​groove 120 not only makes the detachable cylindrical soft-pack battery 10 more securely limited in the battery compartment, This significantly reduces the likelihood of the removable cylindrical pouch battery 10 becoming loose or displaced when subjected to external vibrations or impacts. Furthermore, it ensures that the removable cylindrical pouch battery 10 remains securely contained within the battery compartment during prolonged use, further reducing the possibility of loosening or displacement. This also greatly reduces the likelihood of poor contact between the conductive ends of the removable cylindrical pouch battery 10 and the conductive ends of the battery compartment, thereby significantly improving the installation reliability and operational stability of the removable cylindrical pouch battery 10.

[0052] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
