Abstract

By inducing a strong magnetic field of the electromagnet to the engine valve of the car to apply the manpower and repulsive force to open and close the valve to reduce the power loss, the structure can be manufactured in a simple structure, and the precise opening and closing to improve the performance. Since the valve is opened and closed by driving the rocker arm, there is a difficulty in assembling according to the connection structure and power loss due to mechanical contact. The coil 20 is wound around the mandrel 18 provided at the upper end of the 12 to detect the rotation of the crankshaft 30 with a sensor, convert it into an electrical signal, and convert the valve 12 into a magnetic force generated by the electromagnet 22. Power loss due to electronic operation of valve in cylinder Reduce an effect of simply done making airborne as well as reducing the production costs led to more precise opening and closing valves improves performance by using the structure.

Description

Valve opening and closing device of automobile valve opening and closing mechanism

The present invention relates to an improvement of an intake and exhaust valve for discharging air and waste gas required for engine operation of a vehicle. More particularly, the magnetic force of the electromagnet is induced to the valve to apply an attractive force and repulsive force to open and close the valve. The present invention relates to a valve opening and closing device for a vehicle valve opening and closing mechanism to reduce losses, to allow a simple structure, and to improve performance by precise opening and closing.

In general, a valve operated by a valve opening and closing mechanism of an automobile is disposed in a cylinder to suck a mixer necessary for power administration of a four cycle engine into a combustion chamber and to discharge combustion gas to the outside.

Such a valve is provided with a cam shaft 2 in the cylinder head 1, as shown in FIG. 1, with a cam 3 interlocking with the cam shaft 2, and a rocker arm corresponding to the cam 3, respectively. It is comprised so that the valve 4 may be opened and closed by pin-shaft | pinning (5) and the driving force of the cam 2. As shown in FIG.

Accordingly, when the cam shaft 2 rotates, the cam 3 interlocks to drive the rocker arm 5 corresponding to the cam 3 so that the valve 4 opens and closes at the cylinder head 1. To achieve the intake and exhaust stroke.

However, since the valve is opened and closed by driving the cam and rocker arm, it has difficulty in assembling according to the connection structure and power loss due to mechanical contact. .

Accordingly, the present invention has been made in order to solve the above-mentioned drawbacks, the purpose of which is to open and close the operation of the valve by an electronic valve, while reducing the power loss, the simple opening and closing of the automobile valve can be obtained stable performance by precise opening and closing It is to provide a valve opening and closing device of the mechanism.

The present invention for achieving the above object is that the valve which is disposed in the cylinder head 10 is transmitted to the rotational force of the crankshaft to achieve the vertical movement opening and closing the cylinder of the cylinder head,

The coil is wound around the mandrel provided on the upper end of the valve to detect the rotation of the crankshaft by a sensor, converts it into an electrical signal, and is configured to open and close as the valve moves up and down by a magnetic force generated by an electromagnet. It is achieved by technical means configured to be spaced apart from the upper end of the valve by a predetermined gap.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is a front view of the present invention and FIG. 3 is a configuration diagram of the valve device according to the present invention. Referring to these drawings, the valve opening and closing device of the valve opening and closing mechanism for an automobile according to the present invention includes a cylinder head 10 having a cylinder 40. In the valve 12 which is disposed in the crankshaft 30 and the rotational force of the crankshaft 30 is transmitted to form a vertical movement, the opening and closing of the cylinder 40 of the cylinder head 10,

The mandrel 18 is disposed on the upper end of the valve 12, and the coil 20 is wound around the mandrel 18 to form an electromagnet 22.

In addition, the electromagnet 22 provided in the mandrel 18 is configured to sense the rotation of the crankshaft 30 with a sensor, convert it into an electrical signal, and generate a magnetic force to achieve the opening and closing operation of the valve 12 by vertical movement. It is becoming.

In addition, the core rod 18 wound around the coil 20 is configured to be spaced apart from the upper end of the valve 12 by a predetermined gap.

In the present invention having such a configuration, magnetic force is generated in the electromagnet 22 provided by the coil 20 wound around the core rod 18 by arranging the core rod 18 at a predetermined gap on the upper end of the valve 12. The valve 12 is detected by the magnetic force generated by the electromagnet 22 provided by the coil 20 wound on the mandrel 18 by detecting the rotation of the crank shaft 30 by a sensor and converting it into an electrical signal again. Opening and closing operation is achieved in the cylinder 40 of the cylinder head 10.

Therefore, the valve 12 for opening and closing the cylinder 40 of the cylinder head 10 is not operated by the mechanical contact of the rocker arm which is interlocked with the camshaft, but the valve acts electronically by the magnetic force of the electromagnet, thereby reducing the power loss. It is possible to achieve precise movement.

The present invention composed of the above configuration has the effect of improving the performance of the valve by performing the electronic operation in the cylinder to reduce the power loss and simplify the structure to achieve a more precise valve opening and closing while reducing manufacturing costs and manufacturing costs .
