Description

Technical Field

[0001] This utility model relates to the field of discharge equipment technology, specifically to a starting device with a self-demagnetizing power bank emergency starting power supply. Background Technology

[0002] With the rapid development of the automotive industry, car jump starters have become an essential tool for many car owners. Traditional jump starters mostly adopt an integrated design, where the power supply and emergency starting components are combined. While this design simplifies the usage process to some extent, it also brings some inconveniences. First, integrated jump starters are difficult to carry and store due to their larger size during packaging and transportation. Furthermore, if either the power supply or the emergency starting component fails, the entire device may need to be replaced, increasing operating costs. Moreover, the location of the emergency starting interface may vary depending on the car model, limiting the flexibility of the integrated design. Utility Model Content

[0003] In view of the above-mentioned defects of the prior art, the purpose of this utility model is to provide a starting device with a self-demagnetizing power bank emergency starting power supply.

[0004] The technical solution of this utility model is: a starting device with a self-demagnetizing power bank emergency starting power supply, including a power bank and a self-demagnetizing emergency starting device, which are detachably connected by a separate plug-in connection.

[0005] Furthermore, one end of the power bank is equipped with a positive output interface and a negative output interface, and the self-demagnetizing emergency start device has a positive input connector and a negative input connector, which are respectively inserted into the positive output interface and the negative output interface.

[0006] Furthermore, the self-demagnetizing emergency start device is an emergency start box. The positive and negative input terminals are located at one end of the emergency start box, and the other end of the emergency start box is connected to two alligator clips via wires.

[0007] Furthermore, the self-demagnetizing emergency start device consists of two separate independent emergency start boxes, one of which has a positive input connector and the other has a negative input connector. Each of the two separate independent emergency start boxes is connected to an alligator clip.

[0008] Furthermore, the starting device with self-demagnetizing power bank emergency starting power supply includes a controller. The controller is connected to a power information display module, a first LED light, a one-button zero-power-consumption power-on / off module, a battery balancing management module, a voltage signal detection module, a bulging detection module, a wireless charging module, and a USB bidirectional control module. The battery balancing management module is connected to the voltage signal detection module and the bulging detection module. The wireless charging module is connected to the USB bidirectional control module and the first LED light. The one-button zero-power-consumption power-on / off module is connected to the voltage signal detection module.

[0009] Furthermore, the controller is connected to a single-plug high-current output module, the bulging detection module is connected to the single-plug high-current output module, the single-plug high-current output module is connected to a second LED light; the bulging detection module is connected to a single-plug high-current connection cable.

[0010] Furthermore, the one-button zero-power power-on / off module includes: a button switch circuit, a power-off detection circuit, a self-locking circuit, and a main control module; the button switch circuit includes a button SW3, which is connected to the positive power supply terminal BAT+; the power-off detection circuit is connected in series between the positive power supply terminal BAT+ and the input terminal of the main control module via the button SW3; the self-locking circuit includes a MOSFET Q15, a transistor Q16, resistors R84, R85, and R87; the collector of transistor Q16 is connected to the gate of MOSFET Q15 via resistor R84; the source of MOSFET Q15 is connected to the positive power supply terminal BAT+; resistors R85 and R87 are connected in series between the drain of MOSFET Q15 and the base of transistor Q16 to form a self-locking circuit; the common terminal of resistors R85 and R87 is connected to the output terminal of the main control module.

[0011] Button SW3 is connected to the base of transistor Q16 through a voltage divider resistor. Pressing button SW3 causes transistor Q16 to saturate and conduct, which in turn turns on the MOSFET, thus powering on the device. Pressing button SW3 again causes the power-off detection circuit to detect the voltage and transmit it to the main control module. The main control module then outputs a low level, which turns off transistor Q16 and disconnects the MOSFET Q15, thus powering off the device.

[0012] Furthermore, the one-button zero-power-consumption power-on / off module automatically shuts down all input and output functions when the emergency power supply with self-demagnetizing charging bank stops working, achieving zero current consumption.

[0013] Furthermore, the bulging detection module includes a first metal sheet and a second metal sheet. The first metal sheet is fixed to the upper surface of the lithium battery, and the second metal sheet is fixed to the inner wall of the upper shell of the lithium battery. When the first metal sheet comes into contact with the second metal sheet, it feeds back to the battery equalization management module. The battery equalization management module determines that the lithium battery has bulged and promptly stops the input or output function of the device with the self-demagnetizing power bank emergency start-up power supply.

[0014] Furthermore, the emergency starter with self-demagnetization uses a relay as a high-current output control switch. When the relay contacts are closed and a large DC current passes through, the magnetic field generated by the current magnetizes the contact circuit and prevents it from separating and shutting off normally. The emergency starter with self-demagnetization sets a permanent magnet inside the relay to reverse the magnetic field generated by the large DC current, so that the magnetic fields cancel each other out and achieve the purpose of demagnetization.

[0015] The beneficial effects of this utility model are as follows: Through the separate, detachable, pluggable connection design of the power bank and the self-demagnetizing emergency start device, users can carry the power bank or the device separately as needed, greatly improving the portability and flexibility of the device. This design also facilitates the storage and transportation of the device and reduces space occupation. When a part of the power bank or the device malfunctions, the user only needs to replace the damaged part instead of replacing the whole device, thereby reducing the cost of use. In addition, this modular design simplifies the maintenance process and improves the maintainability of the device. Attached Figure Description

[0027] Example 1: As Figure 8 As shown, the starting device is an emergency starter power supply with a self-demagnetizing power bank, including a power bank 1 and an emergency starter with a self-demagnetizing function. The power bank 1 and the emergency starter with a self-demagnetizing function are detachably connected via a separate plug-and-play connection. One end of the power bank 1 is provided with a positive output interface 101 and a negative output interface 102. The emergency starter with a self-demagnetizing function has a positive input connector 4 and a negative input connector 5, which are respectively inserted into the positive output interface 101 and the negative output interface 102. The emergency starter with a self-demagnetizing function is an emergency starter box 2. The positive input connector 4 and the negative input connector 5 are located at one end of the emergency starter box 2, and the other end of the emergency starter box 2 is connected to two alligator clips (not shown in the figure) via wires.

[0028] like Figure 1 — Figure 7 As shown, the power bank 1 emergency jump starter includes a controller 6. The controller 6 is connected to a power information display module 7, a first LED light 8, a one-button zero-power on / off module 9, a battery balancing management module 10, a voltage signal detection module 11, a bulge detection module 12, a wireless charging module 13, and a USB bidirectional control module 14. The battery balancing management module 10 is connected to the voltage signal detection module 11 and the bulge detection module 12. The wireless charging module 13 is connected to the USB bidirectional control module 14 and the first LED light 8. The one-button zero-power on / off module 9 is connected to the voltage signal detection module 11. The controller 6 is connected to a single-plug high-current output module 15. The bulge detection module 12 is connected to the single-plug high-current output module 15, and the single-plug high-current output module 15 is connected to a second LED light 16. The bulge detection module 12 is connected to a single-plug high-current connection cable 17.

[0029] The one-button zero-power power-on / off module 9 includes: a button switch circuit, a power-off detection circuit, a self-locking circuit, and a main control module; the button switch circuit includes a button SW3, which is connected to the positive power supply BAT+; the power-off detection circuit is connected in series between the positive power supply BAT+ and the input terminal of the main control module via button SW3; the self-locking circuit includes a MOSFET Q15, a transistor Q16, resistors R84, R85, and R87; the collector of transistor Q16 is connected to the gate of MOSFET Q15 via resistor R84; the source of MOSFET Q15 is connected to the positive power supply BAT+; resistors R85 and R87 are connected in series between the drain of MOSFET Q15 and the base of transistor Q16 to form a self-locking circuit; the common terminal of resistors R85 and R87 is connected to the output terminal of the main control module.

[0030] Button SW3 is connected to the base of transistor Q16 through a voltage divider resistor. Pressing button SW3 causes transistor Q16 to saturate and conduct, which in turn turns on the MOSFET, thus powering on the device. Pressing button SW3 again causes the power-off detection circuit to detect the voltage and transmit it to the main control module. The main control module then outputs a low level, which turns off transistor Q16 and disconnects the MOSFET Q15, thus powering off the device.

[0031] The one-click zero-power power-on / off module 9 automatically shuts down all input and output functions when the power bank 1 emergency start-up power supply stops working, achieving zero current energy consumption.

[0032] The bulging detection module 12 includes a first metal sheet and a second metal sheet. The first metal sheet is fixed to the upper surface of the lithium battery, and the second metal sheet is fixed to the inner wall of the upper shell of the lithium battery. When the first metal sheet comes into contact with the second metal sheet, it feeds back to the battery equalization management module 10. The battery equalization management module 10 determines that the lithium battery has bulged and promptly stops the input or output function of the emergency power supply of the power bank 1.

[0033] The emergency start device with self-demagnetization uses a relay as a high-current output control switch. When the relay contacts are closed and a large DC current passes through, the magnetic field generated by the current magnetizes the contact circuit and prevents it from separating and turning off normally. The emergency start device with self-demagnetization sets a permanent magnet inside the relay to reverse the magnetic field generated by the large DC current, so that the magnetic fields cancel each other out and achieve the purpose of demagnetization.

[0034] Example 2: Figure 9 As shown, the difference between Embodiment 2 and Embodiment 1 is that the self-demagnetizing emergency start device consists of two separate independent emergency start boxes 3. One of the separate independent emergency start boxes 3 has a positive input connector 4, and the other separate independent emergency start box 3 has a negative input connector 5. Each of the two separate independent emergency start boxes 3 is connected to an alligator clip (not shown in the figure).

[0035] This invention features a separate, detachable, pluggable design for the power bank 1 and the self-demagnetizing emergency start device. Users can carry either the power bank 1 or the device separately as needed, greatly improving the portability and flexibility of the device. This design also facilitates storage and transportation, reducing space occupancy. When a part of the power bank 1 or the device malfunctions, users only need to replace the damaged part, rather than replacing the entire device, thus reducing operating costs. Furthermore, this modular design simplifies the maintenance process and improves the maintainability of the device.

[0036] This utility model achieves intelligent management of the emergency power supply of the power bank 1 through the integrated controller 6 and its related modules (such as power information display, one-click zero-power switch, battery equalization management, etc.). In particular, the one-click zero-power switch module 9 can automatically shut down all input and output functions when the device stops working, achieving zero current consumption, effectively extending the service life of the device and saving energy.

[0037] The bulging detection module 12 of this utility model is designed to detect the swelling of the battery in a timely manner and immediately stop the input or output function of the device, effectively preventing safety accidents caused by battery failure and improving the safety performance of the device.
