Technical Field
[0001] This utility model relates to the field of mobile power supply technology, specifically a mobile power supply that utilizes a physical structure to cut off power. Background Technology
[0002] With the widespread use of portable electronic devices, power banks have become an indispensable power supply device for people's daily work, life, and travel. Whether it is consumer electronics such as smartphones and tablets, or smart wearable devices and small office equipment, their battery life is often insufficient to meet the needs of long-term outdoor use or long-distance travel. Power banks, with their advantages of portability and efficient power replenishment, effectively solve this pain point, and the market demand continues to rise.
[0003] However, existing power banks suffer from significant standby power loss issues in their technical design. Traditional power banks typically use electronic switches or logic control circuits to connect the battery and motherboard. Even in standby mode, when no external devices are connected and no power is required, the motherboard remains in a low-power operating mode, continuously consuming battery power. This standby power loss not only shortens the power bank's standby time, causing rapid power loss during long-term storage or carrying, resulting in insufficient power delivery during use, but also accelerates battery aging due to repeated low-power consumption, reducing battery cycle life and increasing user costs.
[0004] Therefore, developing a portable power bank that can effectively cut off standby power loss and completely disconnect the battery from the motherboard through physical isolation, thereby extending standby time and service life, has become an important direction to meet users' actual needs and make up for the shortcomings of existing technologies. Summary of the Invention
[0005] The purpose of this invention is to provide a portable power bank that utilizes a physical structure to cut off power, aiming to solve the problems of continuous power loss, short standby time, and reduced battery life of existing portable power banks in standby mode.
[0006] This utility model is implemented as follows: a mobile power supply that utilizes a physical structure to cut off power includes a housing, a physical isolation switch assembly, a circuit board, and a battery disposed inside the housing. The input terminal of the physical isolation switch assembly is electrically connected to the battery, and the output terminal of the physical isolation switch assembly is electrically connected to the circuit board. The physical isolation switch assembly is used to control the physical connection and disconnection of the circuit between the battery and the circuit board.
[0007] Furthermore, the physical isolation switch assembly is configured as a normally open or normally closed switch.
[0008] Furthermore, the physical disconnect switch assembly includes a base and a cover, the cover being detachably fastened to the base, and the two forming a mounting cavity. A fixed end is provided in the mounting cavity, and an electrical connection socket is provided on the fixed end, the electrical connection socket being connected to a first connecting wire. A movable end is slidably disposed in the mounting cavity, and a metal plug is provided on the movable end, the metal plug being connected to a second connecting wire. The first and second connecting wires are electrically connected to the battery and the circuit board, respectively. A push button is connected to the movable end, the push button causing the movable end to slide along the mounting cavity, allowing the metal plug to be inserted into or removed from the electrical connection socket, thereby realizing the physical switching of the circuit between the battery and the circuit board.
[0009] Furthermore, a first magnetic attractor is provided on the fixed end, and a second magnetic attractor is provided on the movable end. When the metal plug is inserted into the electrical connection socket, the first magnetic attractor and the second magnetic attractor attract each other.
[0010] Furthermore, the mobile terminal is provided with a linkage hole, and the push button is provided with a limit foot. The limit foot is inserted into the linkage hole so that the push button moves synchronously with the mobile terminal.
[0011] Furthermore, the upper surface of the cover is provided with a mounting groove, the mounting groove is provided with a clearance hole, the push key is provided in the mounting groove, and its limiting foot passes through the clearance hole and is connected to the linkage hole of the moving end.
[0012] Furthermore, the upper end of the cover is flush with or partially exposed to the outer wall of the housing, and an observation window made of transparent material is provided on the cover at the position where the metal plug is connected to the electrical connection socket.
[0013] Furthermore, the housing wall is provided with a display screen, a charging socket, and a push-button switch, all of which are electrically connected to the circuit board.
[0014] Furthermore, a charging cable assembly is provided on the outside of the housing. The charging cable assembly includes a first charging cable and a second charging cable. One end of the first charging cable and the second charging cable passes through the housing and is connected to the circuit board. The other end is provided with a first charging plug and a second charging plug, respectively.
[0015] Furthermore, the charging cable assembly also includes a fixing bracket, which has a first fixing groove and a second fixing groove. The first charging plug and the second charging plug are respectively disposed in the first fixing groove and the second fixing groove. Both ends of the first fixing groove are open, and the openings are of different sizes, and the first charging plug can only pass through the larger opening.

[0021] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: like Figures 1-3 As shown, a portable power bank utilizing physical structure for power disconnection includes a housing 1, a physical isolation switch assembly 2, a circuit board 3, and a battery 4 disposed inside the housing 1. A display screen 5, a charging socket 6, and a push-button switch 7 are mounted on the housing wall of the housing 1. The input terminal of the physical isolation switch assembly 2 is electrically connected to the battery 4, and the output terminal is electrically connected to the circuit board 3. The physical isolation switch assembly 2 is configured as a normally open or normally closed switch, used to control the physical connection and disconnection of the circuit between the battery 4 and the circuit board 3. The display screen 5, charging socket 6, and push-button switch 7 are all electrically connected to the circuit board 3. The display screen 5 can be used to display the battery's charge level and charging status. The charging socket is used to connect a charging cable and an external power source to charge the battery 4, and can also be used as a charging output interface. The push-button switch 7 is a power switch used to control the power supply to the circuit board 3, and can work with the physical isolation switch assembly 2 to achieve tiered power disconnection management of the portable power bank.
[0022] like Figure 1 , Figure 3 and Figure 4As shown, the physical disconnect switch assembly 2 includes a base 21 and a cover 22. The cover 22 is fastened to the base 21 by a snap-fit structure. The snap-fit structure includes snap blocks on the cover 22 and corresponding slots on the base 21, or the snap-fit structure includes slots on the cover 22 and corresponding snap blocks on the base 21. The base 21 and the cover 22 form a mounting cavity 23. A fixed end 24 and a movable end 26 are provided in the mounting cavity 23. The movable end 26 is slidably disposed in the mounting cavity 23. The fixed end 24 is provided with an electrical connection socket 241, and a metal wire is provided on the inner wall of the socket. The electrical connection socket 241 is connected to a first connecting wire 25. The movable end 26 is provided with a metal plug 261, which is connected to a second connecting wire 27. The first connecting wire 25 and the second connecting wire 27 are electrically connected to the battery 4 and the circuit board 3, respectively. The mobile terminal 26 is connected to a push button 28, which can drive the mobile terminal 26 to slide along the mounting cavity 23, so that the metal plug 261 can be inserted into or removed from the electrical connection socket 241, thereby realizing the physical switching of the circuit between the battery 4 and the circuit board 3.
[0023] like Figure 4 As shown, a first magnetic clasp 242 is provided on the fixed end 24, and a second magnetic clasp 262 is provided on the movable end 26. When the metal plug 261 is inserted into the electrical connection socket 241, the first magnetic clasp 242 and the second magnetic clasp 262 attract each other. The first magnetic clasp 242 and the second magnetic clasp 262 securely maintain the insertion and engagement of the metal plug 261 and the electrical connection socket 241, preventing accidental circuit disconnection due to vibration or collision during use, and improving the reliability of circuit continuity.
[0024] like Figure 4 As shown, the mobile end 26 is provided with a linkage hole 263, and the push button 28 is provided with a limiting foot 281. The limiting foot 281 is inserted into the linkage hole 263, so that the push button 28 moves synchronously with the mobile end 26. The upper surface of the cover 22 is provided with a mounting groove 221, and the mounting groove 221 is provided with a clearance hole 222. The push button 28 is set in the mounting groove 221, and its limiting foot 281 passes through the clearance hole 222 and connects to the linkage hole 263 of the mobile end 26. The mounting groove 221 and the clearance hole 222 must be of sufficient length so that the push button 28 can drive the mobile end 26 to complete the sliding stroke along the mounting cavity 23 from the metal plug 261 being fully inserted into the electrical connection socket 241 to being fully disengaged, ensuring effective switching of the circuit on and off states. The upper end of the housing 1 is provided with a through hole for the cover 22 to pass through. The upper end of the cover 22 is flush with or partially exposed with the outer wall of the housing 1, so that the user can easily operate the push button 28. The cover 22 has a transparent viewing window 29 at the position where the metal plug 261 is connected to the electrical connection socket 241, so that the user can intuitively see the insertion or disconnection status of the metal plug 261.
[0025] like Figure 1 and Figure 5 As shown, a charging cable assembly 8 is provided on the outside of the housing 1. The charging cable assembly 8 includes a first charging cable 81, a second charging cable 82, and a fixing bracket 83. One end of the first charging cable 81 and the second charging cable 82 passes through the housing 1 and is connected to the circuit board 3. The other end is provided with a first charging plug 811 and a second charging plug 821, respectively. The fixing bracket 83 is provided with a first fixing groove 831 and a second fixing groove 832. The first charging plug 811 and the second charging plug 821 are respectively disposed in the first fixing groove 831 and the second fixing groove 832. Both ends of the first fixing groove 831 are open, and the openings are of different sizes. The first charging plug 811 can only pass through the larger opening. A through-hole 833 is provided on one side wall of the first fixing groove 831, which connects the two openings of the first fixing groove 831. The first charging cable 81 can pass through the through-hole 833. The first charging cable 81 has three position states: a retracted state, a semi-extended state, and a fully extended state. In the retracted state, the first charging plug 811 is secured within the first fixing slot 831. In the semi-extended state, the first charging plug 811 extends out of a large opening, suitable for short-distance charging scenarios. In the fully extended state, the first charging plug 811 is completely detached from the first fixing slot 831, and the first charging cable 81 passes through the through-hole 833, suitable for longer-distance and more flexible charging needs. The second fixing slot 832 has openings at both ends, with different opening sizes. The second charging plug 821 can only pass through the larger opening. The second charging cable 82 also has three position states: retracted, semi-expanded, and fully expanded. In the retracted state, the second charging plug 821 is secured in the second fixing slot 832. In the semi-expanded state, part of the second charging plug 821 protrudes from the larger opening, suitable for short-distance charging scenarios. In the fully expanded state, the second charging plug 821 is completely detached from the second fixing slot 832, meeting the needs for longer-distance and more flexible charging. Moreover, the fixing bracket 83 will not completely detach from the second charging cable 82 at this time, so that the fixing bracket 83 will not be lost.
[0026] In addition, such as Figure 1 As shown, when the first charging cable 81 and the second charging cable 82 are both in the storage state, the first charging cable 81, the second charging cable 82 and the fixed card holder 83 form a hanging rope structure, which is convenient for carrying.
[0027] In summary, this invention achieves physical on / off control of the circuit between the battery 4 and the circuit board 3 by setting up a physical isolation switch assembly 2, which can completely disconnect the circuit connection between the battery 4 and the circuit board 3. Compared with traditional electronic switches, it effectively avoids the problem of continuous power loss after the circuit is disconnected, and at the same time helps to improve standby time and battery life.
[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
