Problems solved by technology
[0002] At present, most automobiles adopt a master control structure. When the electronic control unit (ECU), circuit, throttle system, intake system, accelerator pedal, and accelerator mechanical connection system of the automobile fail or are affected, the engine cannot reset to idle state. It will be very dangerous, because the high-speed engine works with high power, the vehicle may run at high speed, so braking the vehicle will not stop the vehicle immediately, and there is a high possibility of sideslip or violent collision; turning off the car key may be more dangerous, because After the engine is turned off, the brake booster system, steering system, ABS system, body stabilization system, etc. may also be turned off, and the steering wheel may even be locked, which is extremely dangerous; It will still run at high speed, and the brake assist system, steering system, ABS system, body stability system and other systems may not work properly due to the high speed of the engine

Embodiment Construction
[0011] The structure and operating principle of the automobile idling safety device of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0012] As shown in the accompanying drawings, the automobile idling safety device of the present invention includes an air inlet 1 and a throttle mechanism 2, on which the throttle mechanism 2 is provided with a forced throttle closer 3, and the throttle forced closer 3 is electrically connected with an idle safety Switch 4, when the idle speed safety switch 4 is in the open state, the throttle valve will be closed forcibly, and only the normal idle speed of the engine will be maintained; , circuit, throttle system, accelerator pedal, throttle mechanical connection system, etc. are faulty or affected, and the engine cannot reset to idle state, the driver or co-pilot can directly turn on the idle safety switch. The throttle valve only keeps the engine at normal idle speed, preventi...

The invention discloses an auto idle speed safety device, which belongs to the technical field of auto control mechanisms and has the main technical characteristics that: the device comprises a throttle mechanism, a throttle forced closer is arranged at the throttle mechanism and electrically connected with an idle speed safety switch, when the idle speed safety switch is in an opening state, the throttle is forcibly closed and an engine only keeps an normal idle speed; when the idle speed safety switch is in a closed state, the throttle operates normally. When a singlechip electronic control unit, lines, a throttle system, an accelerator pedal and an accelerator mechanical connect system and the like of an automobile have a fault or are affected, and the engine cannot reset to the idle state, a driver or co-pilot can directly open the idle safety switch, so that the throttle forced closer forcibly closes the throttle and the engine only keeps a normal idle speed. Thus, accidents are avoided.
