Description

Technical Field

[0001] This application relates to the technical field of mobile battery cells, and in particular to a mobile power supply that facilitates battery cell replacement. Background Technology

[0002] Currently, charging small mobile devices primarily relies on AC mains power, using a charging socket to convert 220V to 5V to replenish their power. In situations where AC mains power is inconvenient or during disasters, portable power banks or other portable chargers are effective supplementary methods for charging small mobile devices.

[0003] Most current portable power banks and similar devices use multiple battery cells connected in series, requiring specialized welding equipment to process them before they can operate. If a single battery cell malfunctions, the entire device becomes unusable, necessitating cell replacement. However, cell replacement requires welding, making it a highly specialized process and inconvenient for users. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a portable power bank with easily replaceable battery cells, which has the advantages of facilitating battery cell replacement and ensuring the normal operation of the portable power bank.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A portable power bank with easy-to-replace battery cells includes battery cells and a fixing shell for fixing electrical properties. A circuit board is disposed on the fixing shell, and a quick connector for interconnection is disposed between the circuit board and the battery cells.

[0007] The quick-connect component includes a pair of inverted "V"-shaped pins. The two pins are electrically connected to the positive and negative poles of the circuit board, respectively. The fixing shell is provided with positioning grooves for the pins to engage one by one. The two positioning grooves are correspondingly set with the two poles of the battery cell, and the two pins abut against the two poles of the battery cell.

[0008] The fixing shell includes a base and a top cover that are fastened to the outside of the battery cell, and a locking element is provided between the base and the top cover for locking them together.

[0009] To achieve the above technical solution, during assembly, simply place the battery cell on the base, then fasten the top cover onto the base, and finally use the locking assembly to press and lock the top cover onto the base, thus securing the battery cell. Simultaneously, the pin on the top cover gradually presses against the terminals on the battery cell, connecting the two terminals of the battery cell to the pin, thereby supplying power to the circuit board. When the battery cell becomes depleted and damaged due to prolonged disuse, simply open the base and top cover using the locking assembly, remove the old battery cell, replace it with a new one, and then lock it back in place. Replacement is completed without soldering, facilitating user operation and maintenance. Furthermore, the "U"-shaped design ensures a tight connection between the pin and the battery cell, reducing the occurrence of arcing due to loose connections and thus extending the battery's lifespan.

[0010] As a preferred embodiment of this application, the upper cover is provided with a bracket for mounting the circuit board, and the bracket is provided with a clearance groove for the pin to pass through.

[0011] The above technical solution ensures that the pin is constrained by the bracket, thereby guaranteeing the stability of the pin.

[0012] As a preferred embodiment of this application, the upper cover is provided with a rotating handle.

[0013] The above technical solution allows personnel to carry the handle to the place where it is needed.

[0014] As a preferred embodiment of this application, the locking element includes a screw and nut.

[0015] To achieve the above technical solution, the bottom support and the top cover are locked together with screws and nuts, thereby securing the battery cell.

[0016] As a preferred embodiment of this application, the top cover is provided with a USB output port that is connected to the circuit board.

[0017] The above technical solution is implemented to ensure normal output results.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. During assembly, simply place the battery cell on the base, then fasten the top cover onto the base. The locking assembly then presses the top cover firmly against the base, securing the battery cell. Simultaneously, the pin on the top cover gradually presses against the terminals on the battery cell, connecting the two terminals to the pin and supplying power to the circuit board. When the battery cell becomes depleted and damaged due to prolonged disuse, simply open the base and top cover using the locking assembly, remove the old battery cell, and replace it with a new one. Locking the old battery cell back in place completes the replacement process without soldering, facilitating use and maintenance. The "U"-shaped design ensures a tight connection between the pin and the battery cell, reducing the risk of arcing due to loose connections and extending the battery's lifespan.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] This application discloses a portable power bank that facilitates the replacement of battery cell 1. (Refer to...) Figure 1 The portable power supply that facilitates the replacement of the battery cell 1 includes the battery cell 1 and a fixing shell 2 for fixing the electrical properties. A circuit board 3 is provided on the fixing shell 2, and a quick connector 4 for interconnection is provided between the circuit board 3 and the battery cell 1.

[0027] The fixing shell 2 includes a bottom support 21 and a top cover 22 that are fastened to the outside of the battery cell 1. A locking member 5 for locking each other is provided between the bottom support 21 and the top cover 22. In this application, the locking member 5 is a screw and nut. The bottom support 21 and the top cover 22 are locked together by the screw and nut, thereby holding and fixing the battery cell 1.

[0028] The quick-connect component 4 includes a pair of inverted "V"-shaped pins 41. The two pins 41 are electrically connected to the positive and negative terminals of the circuit board 3, respectively. The fixing housing 2 is provided with positioning grooves 42 for the pins 41 to engage one by one. The two positioning grooves 42 are correspondingly set with the two terminals 11 of the battery cell 1, and the two pins 41 abut against the two terminals 11 of the battery cell 1. Thus, during assembly, it is only necessary to place the battery cell 1 on the base 21, then fasten the top cover 22 onto the base 21, and then press and lock the top cover by the locking component 5 assembly. The base 21 holds the battery cell 1 securely, while the pin 41 on the top cover 22 gradually presses against the terminals 11 on the battery cell 1, connecting the two terminals 11 of the battery cell 1 with the pin 41, thus supplying power to the circuit board 3. When the battery cell 1 is depleted and damaged due to prolonged disuse, simply open the base 21 and top cover 22 using the locking device 5, remove the old battery cell 1, replace it with a new one, and then lock it back in place using the locking device 5. Replacement of the battery cell 1 is completed without soldering, facilitating user operation and maintenance. The "U"-shaped design ensures a tight connection between the pin 41 and the battery cell 1, reducing the occurrence of arcing due to loose connections and thus extending its service life.

[0029] The top cover 22 is provided with a bracket 6 for mounting the circuit board 3. The bracket 6 is provided with a relief groove 61 for the pin 41 to pass through, thereby restricting the pin 41 by the bracket 6 and ensuring the stability of the pin 41. The top cover 22 is provided with a USB output port 7 connected to the circuit board 3, thereby ensuring normal output.

[0030] To facilitate use, the cover 22 is equipped with a rotating handle 8, which allows people to carry it to the place where it is needed.

[0031] The implementation principle of a portable power bank with easy-to-replace battery cell 1 according to an embodiment of this application is as follows: During assembly, the battery cell 1 is simply placed on the base 21, and then the top cover 22 is fastened onto the base 21. The locking assembly 5 then presses and locks the top cover onto the base 21, thus securing the battery cell 1. Simultaneously, the pin 41 on the top cover 22 gradually presses against the terminals 11 on the battery cell 1, thereby connecting the two terminals 11 of the battery cell 1 with the pin 41, and then supplying power to the circuit board 3. When the battery cell 1 is depleted and damaged due to prolonged disuse, the base 21 and top cover 22 can be opened using the locking assembly 5, the old battery cell 1 can be removed and replaced with a new one, and then the locking assembly 5 can be used to lock the battery cell 1 in place. No soldering is required, making it convenient for personnel to use and maintain. Furthermore, the "U"-shaped design ensures a tight connection between the pin 41 and the battery cell 1, reducing the occurrence of arcing due to loose connections, thus ensuring service life.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
