Description

Automobile sudden start prevention device

The present invention relates to a device for preventing sudden start and departure of a vehicle, and more particularly, is installed in a power transmission structure between a throttle valve and a motor of a vehicle, and when the motor is operated by an electric error without the driver stepping on an accelerator pedal, It relates to a sudden start prevention device of the vehicle to prevent the sudden start by mechanically blocking the transmission of power to the throttle valve.

In general, when the driver presses the accelerator pedal, air is supplied to the engine while the throttle valve is opened, and the amount of fuel is increased by the amount of air supplied, so that the engine's RPM increases and oscillates with the force.

In recent years, as the electronic control method by the ECU has been widely adopted in automobiles, sudden oscillation often occurs in a vehicle equipped with an automatic transmission. The electronic control unit has a fuel injection, an ignition timing, and a supply of a mixer. It is widely applied from engine control such as brake system and transmission.

In an electronically controlled engine, a desired engine output is obtained by injecting fuel so as to have an appropriate air-fuel ratio based on the amount of air introduced, and fuel reduction and exhaust gas reduction are achieved. The exact cause of sudden oscillation caused by the installation of the electronic control engine and the electronic control automatic transmission is not known, but it is a malfunction during the signal transmission process between the electronic control unit (ECU) and the automatic transmission control unit (TCU). Due to the inflow of secondary voltage noise), the car's engine suddenly starts to rise regardless of the driver's intention, as the engine's arpm rises sharply even though the accelerator pedal is not pressed at the start, drive or reverse positions. have.

Many attempts have been made to prevent vehicle rush, but there are no proposals to solve the problem fundamentally, and this causes a problem of enormous loss of life and property.

The upper plate 420 and the relay gear 400 are moved upward along the inclined surface SL of the protrusion 734. In the present embodiment, the lower protrusion 730 and the upper protrusion 430 is composed of two each on the left and right sides for stability, but only one may be installed.

Subsequently, the relay gear separating means includes a support plate 800 fitted to the outer surface of the relay gear 400 at the bottom of the rotating plate 700. The supporting plate 800 is assembled to be fitted between the rotary plate 700 and the relay gear 400 by the boss 810 extending upward in the upper surface, so that the relay gear 400 is rotated on the inner surface of the boss 810 and the rotating plate. 700 is configured to rotate on the outer surface of the boss 810.

In the state where the restoring spring 900 is inserted between the spring seating groove 820 and the spring insertion groove 740, one end is coupled to be fitted into the lower spring fixing groove 822, and the other end is connected to the spring upper fixing groove 742. When the rotary pedal 700 is rotated when the rotary pedal 700 is rotated by being fitted to be fitted, the rotary pedal 700 is restored to its original state by the restoring force of the restoring spring 900 when the accelerator pedal is released.

Subsequently, in the present invention, the pressing spring 910 is installed between the housing 10 and the upper surface of the upper plate 420 so that the coupling protrusion 410 of the relay gear 400 is coupled to the coupling groove 310 of the transmission gear 300. It is configured to provide an elastic force in the direction coupled to. That is, the pressing spring 910 provides an elastic force to elastically press the relay gear 400 downward while maintaining the compressed state when the relay gear 400 is raised.

When the motor (M) is operated in a state in which the accelerator pedal is pressed down, the relay gear 400 and the transmission gear 300 are maintained in a state in which the power is normally operated by the valve shaft ( S) while opening the valve (B) as shown in Figure 3, when the motor (M) is operated by an electrical error in the state without pressing the accelerator pedal occurs when the relay gear disconnect means as shown in Figure 4 The relay gear 400 is forcibly raised so that the relay gear 400 is separated from the transmission gear 300 so that power is cut off and the valve B is automatically closed as shown in FIG. 5 to stop the driving of the vehicle.

In more detail, when the vehicle is in a stopped state as shown in FIG. 1, when the accelerator pedal is pressed to drive the vehicle, the wire W is pulled as shown in FIG. 3 to rotate the rotating plate 700. Rotated. Then, the position of the lower left protrusion 732 and the lower right protrusion 734 rotates while the rotating plate 700 rotates. In this state, the power of the motor M is driven by the driving gear 100. And the transmission gear 300 is transmitted to the relay gear 400, the relay gear 400 is rotated at a predetermined angle. At this time, since the positions of the lower left protrusion 732 and the right lower protrusion 734 are rotated, the upper left protrusion 432 and the right upper protrusion 434 of the upper plate 420 even if the relay gear 400 rotates. The lower left protrusion 732 and the lower right protrusion 734 are not in contact with each other. The relay gear 400 and the driven gear 500 meshed with the relay gear 400 rotate together to open the valve B by rotating the valve shaft S. FIG. Of course, if you release the accelerator pedal to stop the driving of the vehicle, the operation of the motor (M) is stopped and the valve (S) is rotated in the opposite direction by the restoring force of the return spring 600 to close the valve (B). . In addition, the rotating plate 700 is restored to its original state by the restoring force of the restoring spring 900 to pull the wire W into a state as shown in FIG. 1.

On the other hand, when the motor (M) is operated by an electrical error without pressing the accelerator pedal and sudden start occurs, power of the motor (M) is momentarily driven by the driving gear (100), the transmission gear (300), and the relay gear. 400, the driven gear 500 is transferred to the valve shaft S to open the valve B, but since the rotating plate 700 is not rotated, the left lower protrusion 732 and the right lower protrusion ( The position of the 734 is not changed. Therefore, when the relay gear 400 rotates, the lower left protrusion 732 and the right lower protrusion corresponding to the upper left protrusion 432 and the right upper protrusion 434 as shown in FIG. 4. In contact with 734, the upper plate 420 and the relay gear 400 are lifted up along the inclined surface SL. Then, the coupling protrusion 410 of the relay gear 400 is separated from the coupling groove 310 of the transmission gear 300 to be separated from each other, and the power of the motor M is transmitted through the transmission gear 300. Passing to 400 is blocked. Then, as shown in FIG. 5, the valve shaft S is rotated in the opposite direction by the restoring force of the return spring 600 so that the valve B is closed. At this time, while the relay gear 400 also rotates in the opposite direction, the upper left protrusion 432 and the upper right protrusion 434 are separated from the corresponding lower left protrusion 732 and the right lower protrusion 734, and the motor M ) Is operated so that the transmission gear 300 is rotating, so that the coupling protrusion 410 of the relay gear 400 is not inserted into the coupling groove 310 of the transmission gear 300, but the upper portion of the transmission gear 300 is fixed. It is placed on the floor to keep the power from being transmitted. Of course, when the sudden start-up problem is solved, and when the pedal pedals to drive the car again, the transmission gear 300 rotates slowly while the coupling protrusion 410 of the relay gear 400 is the coupling groove 310 of the transmission gear 300. When the matched state with the relay gear 400 is raised while the relay gear 400 is lowered by the restoring force of the pressing spring 910 that was compressed while the coupling protrusion 410 is inserted into the coupling groove 310, Figure 3 It is in a state of transmitting power again.

While the invention has been shown and described in connection with specific embodiments, it will be understood that various modifications and variations can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone can grow up easily.
