Description

Technical Field

[0001] This application relates to the field of power banks, and more particularly to a power bank with a replaceable cable. Background Technology

[0002] In recent years, the shared power bank industry has developed rapidly, leading to a continuous expansion of the power bank market. Generally, a power bank includes: a casing, a main circuit board, a battery module, and a charging cable. The main circuit board is located inside the casing, and the battery module is also located inside the casing and electrically connected to the main circuit board. One end of the charging cable extends into the casing and is electrically connected to the main circuit board, while the other end extends to the outside of the casing and has a charging plug for plugging into the charging port of a mobile phone or other charging device. Currently, most power bank malfunctions are due to broken charging cables or damaged charging plugs; the battery module and main circuit board inside the casing are usually not the problem. Therefore, simply replacing the charging cable will allow the power bank to be used again.

[0003] Replacing the charging plug of a current power bank is quite troublesome. It requires opening the casing, disassembling and separating the circuit board from the battery module, and then removing the circuit board from inside the casing before the charging cable can be replaced. This makes replacing the charging cable cumbersome and inefficient. Summary of the Invention

[0004] To make charging cable replacement simpler and more convenient, and to improve the efficiency of charging cable replacement, this application provides a power bank that is easy to replace the cable.

[0005] The power bank provided in this application, which facilitates cable replacement, adopts the following technical solution:

[0006] A power bank with easy cable replacement includes a housing, a circuit assembly, and a charging assembly. The circuit assembly includes a battery module and a circuit motherboard. The battery module and the circuit motherboard are both fixedly disposed inside the housing, and the circuit motherboard is electrically connected to the battery module.

[0007] The charging assembly includes a charging bracket, a charging motherboard, and multiple charging cables. One end of the housing has a connecting slot, and the charging bracket is detachably connected to the connecting slot. The charging motherboard is fixedly mounted on the charging bracket. Both the charging motherboard and the circuit motherboard are fixedly and electrically connected to connectors. One connector is a female connector, and the other is a male connector. When the two connectors are plugged into each other to achieve electrical connection, the charging motherboard and the circuit motherboard are electrically connected. Each charging cable is mounted on the charging bracket and electrically connected to the charging motherboard.

[0008] Optionally, the female connector has four electrical contact points, such that when the male connector is inserted into the female connector, the female connector grips the pins of the male connector.

[0009] Optionally, the connecting groove has a guide groove, and the charging bracket is fixedly provided with a guide block. When the charging bracket passes through the connecting groove, the guide block passes through and slides into the guide groove.

[0010] Optionally, the groove of the connecting slot is fixedly provided with a plurality of snap-fit ​​blocks, and the charging bracket is provided with a plurality of snap-fit ​​slots. When the charging bracket is inserted into the connecting slot, each of the snap-fit ​​blocks is inserted into and snap-fitted into each of the snap-fit ​​slots.

[0011] Optionally, the charging bracket has multiple wiring slots, and one end of each charging cable passes through each wiring slot.

[0012] Optionally, the charging bracket has a through-hole for connecting screws, and the housing is threaded with a connecting bolt. When the charging bracket and the housing are detachably connected, the connecting bolt passes through and is threaded into the connecting screw hole.

[0013] Optionally, the housing is snapped with a protective cover, which covers the connecting bolts to protect them.

[0014] Optionally, the charging bracket is fixedly provided with at least one pull-out protrusion so that the charging bracket can be pulled out of the connecting slot through the pull-out protrusion.

[0015] Optionally, the charging motherboard is fixedly and electrically connected to multiple infrared lamps, the charging bracket is provided with multiple infrared covers, the charging bracket has multiple infrared slots, each infrared cover is inserted and snapped into each infrared slot, and each infrared cover covers each infrared lamp respectively.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] When the charging cable on a power bank is damaged and needs replacement, the fixed connection between the charging bracket and the shell is released, and the charging bracket is moved away from the connection slot. This disengages the two connectors, causing the charging motherboard and circuit board to disconnect electrically. The charging assembly then detaches from the shell along with the charging bracket. Using tools such as a soldering iron, the damaged charging cable is removed from the charging motherboard and replaced with a new one, achieving a quick replacement of the charging cable. The charging bracket is then re-inserted into the connection slot and fixed to the shell, enabling rapid repair and replacement of the power bank's charging cable. This makes charging cable repair and replacement simpler, more convenient, and more efficient. Alternatively, the entire charging assembly can be replaced for quick cable replacement and repair. This improves upon the cumbersome process of replacing the charging plug in existing power banks, which required opening the shell, disassembling the circuit board and battery module, and then removing the circuit board from inside the shell before the charging cable could be replaced, resulting in a cumbersome and inefficient charging cable replacement.

[0031] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0032] This application discloses a power bank that facilitates cable replacement. (See also...) Figures 1 to 3 A power bank that is easy to replace cables includes a housing 1, a circuit assembly 2 and a charging assembly 3. The circuit assembly 2 is disposed inside the housing 1, and the charging assembly 3 is detachably connected to the housing 1 and electrically connected to the circuit assembly 2.

[0033] Reference Figure 3 The housing 1 has a rectangular shape and includes a front shell 11 and a bottom shell 12, which are snapped together. The circuit assembly 2 includes a battery module 21, a circuit board 22, a wireless charging module 23, and a cell support 24. The battery module 21, circuit board 22, wireless charging module 23, and cell support 24 are all fixedly installed inside the housing 1. The battery module 21 and the wireless charging module 23 are electrically connected to the circuit board 22. The battery module 21 is used to store and supply power to the power bank, the wireless charging module 23 is used to wirelessly charge the device, and the cell support 24 is used to cooperate with the housing 1 to fix the battery module 21, thereby making the position of the battery module 21 inside the housing 1 more stable.

[0034] Reference Figure 3In this embodiment of the application, the circuit board 22 is electrically connected to the lamp board 221. The lamp board 221 is fixedly disposed at one end of the housing 1, and the housing 1 is fixedly disposed with a cover plate 2211 for protecting the lamp board 221. The circuit board 22 is also fixedly and electrically connected to a button 222. A through key hole 2221 is provided on one side of the housing 1, and the button 222 passes through the key hole 2221 to be exposed on the surface of the housing 1.

[0035] Reference Figures 4 to 10 In this embodiment, the charging component 3 includes a charging bracket 31, a charging motherboard 32, and multiple charging cables 33. One end of the housing 1 has a connecting groove 13. The charging bracket 31 is detachably connected to the connecting groove 13 so that the charging component 3 can be detachably connected to the housing 1. The charging motherboard 32 is fixedly mounted on the charging bracket 31. The charging motherboard 32 and the circuit motherboard 22 are both fixedly and electrically connected to connectors. One connector is a female connector 321, and the other connector is a male connector 223. The male connector 223 is connected to the circuit motherboard 22, and the female connector 321 is connected to the charging motherboard 32. When the two connectors are plugged into each other to achieve electrical connection, the charging motherboard 32 and the circuit motherboard 22 are electrically connected. Each charging cable 33 is mounted on the charging bracket 31 and electrically connected to the charging motherboard 32.

[0036] Reference Figure 6 In a further embodiment, the female connector 321 has four electrical contact points, so that when the male connector 223 is inserted into the female connector 321, the female connector 321 holds the pin of the male connector 223 tightly, so that the insertion and engagement between the male connector 223 and the female connector 321 is more stable, and the electrical connection between the charging motherboard 32 and the circuit motherboard 22 is more stable.

[0037] Reference Figure 11 and Figure 12 In a further embodiment, the connecting groove 13 has guide grooves 131 on both sides along the width direction of the housing 1. The guide grooves 131 have a U-shaped structure. The charging bracket 31 is fixedly provided with two guide blocks 311. When the charging bracket 31 passes through the connecting groove 13, the two guide blocks 311 pass through and slide into the two guide grooves 131 respectively, so that the position of the charging bracket 31 passing through the connecting groove 13 is more stable, thereby ensuring the electrical connection between the male connector 223 and the female connector 321. The connecting groove 13 away from the housing 1 has two snap-fit ​​blocks 132 fixedly provided. One end of the charging bracket 31 has two snap-fit ​​grooves 312. When the charging bracket 31 passes through the connecting groove 13, each snap-fit ​​block 132 passes through and snaps into each snap-fit ​​groove 312, thereby making the connection between the charging bracket 31 and the housing 1 more stable.

[0038] Reference Figure 1 , Figure 8 as well as Figure 10 In a further embodiment, the charging bracket 31 has a through-hole connecting screw hole 313, and the housing 1 is threaded with a connecting bolt 14. When the charging bracket 31 and the housing 1 are detachably connected, the connecting bolt 14 passes through and is threaded into the connecting screw hole 313. The face shell 11 has a through-hole connecting hole. When the connecting bolt 14 is threaded into the housing 1, the connecting bolt 14 passes through the connecting hole and is threaded into the bottom shell 12, thereby making the connection between the charging bracket 31 and the housing 1 more stable. Two pull-out protrusions 314 are fixedly provided at one end of the charging bracket 31 so that the charging bracket 31 can be pulled out from the connecting groove 13 by pulling out the protrusions 314. The face shell 11 is snapped and fixed with a protective cover 15. The protective cover 15 covers the connecting bolt 14 and each pull-out protrusion 314 to protect the connecting bolt 14 and each pull-out protrusion 314. The protective cover 15 mainly serves to protect the connecting bolt 14.

[0039] Reference Figure 9 In a further embodiment, the charging bracket 31 has multiple wiring slots 315, and one end of each charging cable 33 passes through each wiring slot 315. Among them, one charging cable 33 is a Tape-C charging cable 33; one charging cable 33 is a Lightning charging cable 33; and one charging cable 33 is a Micro charging cable 33. The charging motherboard 32 is fixed and electrically connected to multiple infrared lamps 322. The charging bracket 31 is provided with multiple infrared covers 316. The charging bracket 31 has multiple infrared slots 3161. Each infrared cover 316 passes through and is snapped into each infrared slot 3161. Each infrared cover 316 covers each infrared lamp 322.

[0040] Reference Figure 3 In a further embodiment, the front shell 11 is provided with a plurality of placement slots 111 and a wire-removing slot 112. The wire-removing slot 112 is connected to each placement slot 111. When each charging cable 33 is not in use, each charging cable 33 is threaded through and snapped into each placement slot 111. When each charging cable 33 is in use, the user can easily remove each charging cable 33 from each placement slot 111 through the wire-removing slot 112. Both the circuit board 22 and the front shell 11 are fixedly provided with a plurality of magnetic suction members 224, so that when the front shell 11 and the bottom shell 12 are connected to each other, each magnetic suction member 224 located on the circuit board 22 is magnetically attracted and fixed to each magnetic suction member 224 located on the front shell 11, thereby further increasing the connection stability between the front shell 11 and the bottom shell 12.

[0041] The implementation principle of a power bank that facilitates cable replacement according to an embodiment of this application is as follows: When the charging cable 33 on the power bank is damaged and needs to be replaced, the protective cover 15 is knocked open from the front shell 11 using a disassembly tool, thereby exposing the connecting bolt 14 from the surface of the front shell 11. Then, the connecting bolt 14 is tightened with a tool to release the fixed connection between the charging bracket 31 and the shell 1. Next, the charging bracket 31 is moved away from the connecting groove 13 by the pull-out protrusions 314, thereby disengaging the two connectors from the plug-in engagement, thereby disengaging the charging motherboard 32 and the circuit motherboard 22 from electrical connection. Subsequently, the charging component 3 is detached from the shell 1 as the charging bracket 31 is detached from the connecting groove 13. Then, the damaged charging cable 33 is removed from the charging motherboard 32 using repair tools such as a soldering iron. The charging cable 33 can be quickly replaced by replacing it with a new one. Then, the charging bracket 31 is re-inserted into the connecting slot 13 and fixedly connected to the housing 1, which enables the quick repair and replacement of the charging cable 33. This makes the repair and replacement of the charging cable 33 simpler, more convenient and more efficient. Alternatively, the entire charging assembly 3 can be replaced directly to achieve quick replacement and repair of the charging cable 33. This improves the problem of the current power bank where it is more troublesome to replace the charging plug. It requires opening the housing 1, disassembling and separating the circuit board 22 from the battery module 21, and then removing the circuit board 22 from inside the housing 1 before the charging cable 33 can be replaced, which makes the replacement of the charging cable 33 more troublesome and inefficient.

[0042] 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.
