Vehicle emergency starting device with hand-operated power generation function

Abstract

The invention provides a vehicle emergency starting device with hand-cranking power generation, and relates to the technical field of vehicles. The vehicle emergency starting device specifically comprises a shell internally provided with a control panel, a hand-cranking power generation assembly, a voltage processing circuit, and an energy storage component, wherein the hand-cranking power generation assembly comprises a rocking handle which is arranged outside the shell, one end of the rocking handle penetrates through the shell and extends towards the interior of the shell, the hand-crankingpower generation assembly further comprises a power generator which is arranged in the shell, the end, facing the shell, of the rocking handle is connected with the power generator through a gear set, the voltage processing circuit is arranged on the control panel and is connected with the generator; the energy storage component is arranged on the control panel, is at least one super capacitor and is connected with the output end of the voltage processing circuit; the energy storage part is provided with a large-current output end. The vehicle emergency starting device has the advantages thatthe super capacitor is used for replacing an ultrahigh-rate lithium battery, a vehicle is started more safely and conveniently, the hand-cranking power generation assembly is additionally arranged tocharge the super capacitor, and the charging is more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle emergency starting device with hand-operated power generation. Background technique [0002] Existing vehicle emergency starting devices all use batteries to ignite and start automobile engines. The batteries used are ultra-high-rate lithium battery packs, usually composed of three ultra-high-rate batteries in series. The rated voltage of a single battery is 3.7V. When fully charged The voltage is 4.2V, and the fully charged voltage of a set of batteries is 12.6V, which is basically the same as the voltage of a lead-acid battery in a car. The instantaneous discharge rate of this battery can reach more than 100C, and some can even reach 200C. If it is a 3A battery, the instantaneous It can output a current of 300A, which can easily drive the starter motor of the vehicle to start the engine of the vehicle. However, the ultra-high-rate lithium battery pack used in the ex...

Problems solved by technology

However, the ultra-high-rate lithium battery pack used in the existing vehicle emergency starting device has a huge output current during operation, usually above 200A, and the inside of the battery is prone to overheating. In severe cases, the diaphragm is damaged and an internal short circuit occurs. It is a dangerous product, and the ultra-high rate lithium battery adopts a more active chemical system, which makes it more dangerous and less safe than the ordinary rate lithium battery, and the working temperature range of the lithium battery is narrow, and the discharge capacity is sharp at low temperature. Decrease, and the lithium battery pack needs to ensure that the battery has enough remaining power to start the car. When the lithium battery pack is stored for a long time and forgets to charge, the car cannot be started, and it is not convenient to charge outdoors, so the limitation is relatively large
