Description

Technical Field

[0001] This invention relates to the field of automotive emergency power supply technology, specifically a 12V and 24V adaptive universal automotive emergency jump starter. Background Technology

[0002] Most car jump starters on the market are currently only available with a single 12V output, suitable only for small vehicles such as sedans and SUVs. Larger vehicles such as trucks, buses, and construction machinery generally use 24V power supply systems and require a separate 24V jump starter. Users facing different voltage vehicle types need to carry two devices, resulting in high operating costs and inconvenience.

[0003] Existing dual-voltage jump starters mostly use a manual toggle switch, which is cumbersome and prone to voltage mismatch due to accidental switching, potentially damaging the vehicle's electrical system or the jump starter itself. This results in insufficient safety and convenience. Therefore, the market lacks a universal emergency jump starter that can automatically identify and switch voltages, and is compatible with both 12V and 24V vehicles. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a 12V / 24V adaptive universal automotive emergency jump starter that is structurally sound, safe to use, and automatically identifies voltage. This allows a single device to be compatible with both passenger cars and commercial vehicles, eliminating the need for manual adjustment, avoiding misoperation, and improving ease of use and safety.

[0005] The technical solution adopted by this invention to solve its technical problem is: a 12V and 24V adaptive universal automotive emergency jump starter, including an energy storage cell group, a voltage switching module, a main control unit, a voltage detection unit, a protection circuit, and output terminals. The energy storage cell group is divided into a first cell group and a second cell group, each cell group outputting a 12V voltage. The voltage switching module connects the two cell groups to the output terminals, achieving parallel output of 12V or series output of 24V under the control of the main control unit. The voltage detection unit is connected to the output terminals, acquiring the external vehicle battery voltage signal in real time and transmitting it to the main control unit. The main control unit automatically determines whether the vehicle voltage is 12V or 24V based on the voltage signal, controlling the voltage switching module to execute the corresponding mode, completing automatic adaptation. Furthermore, the voltage switching module is composed of relay components, which realize the switching between parallel and series states of the battery cell group by combining the switching of parallel and series relays.

[0006] Furthermore, the present invention includes a manual switching switch, which allows for manual mode selection when the automatic mode fails or special needs arise, thereby improving the applicability of the equipment.

[0007] Furthermore, the protection circuit integrates multiple protections including reverse connection, overcurrent, overvoltage, undervoltage, short circuit, and backflow prevention to ensure safe use.

[0008] Furthermore, the device also integrates functions such as charging management, power display, LED lighting, and USB output, expanding its application scenarios.

[0009] The working principle of this invention is as follows: when the positive and negative clips of the output terminal are connected to the vehicle battery, the voltage detection unit immediately collects the battery voltage; if the detected voltage is 12V, the main control unit controls the voltage switching module to connect the two sets of battery cells in parallel and output a large current of 12V for starting; if the detected voltage is 24V, the main control unit controls the two sets of battery cells in series and outputs a voltage of 24V for starting; the whole process does not require manual operation and is automatically completed.

[0010] The beneficial effects of this invention are: A single device is compatible with both 12V passenger vehicles and 24V commercial vehicles, replacing two devices with one, reducing costs and making it easy to carry.

[0011] It automatically identifies the battery voltage and switches modes automatically, eliminating the need for manual operation and preventing damage to equipment and vehicles due to misoperation.

[0012] It features multiple safety protection circuits, making it safer and more reliable to use.

[0013] It integrates multiple functional modules, making it more practical and applicable to a wider range of situations.
