Description

A locking apparatus for vehicle

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a vehicle lock device, and more particularly, to a vehicle lock device in which productivity of a product is improved by reducing the number of parts of a lock device to simplify an assembling process and reduce a material cost.

Generally, a vehicle refers to a device that moves a user, including a wheel. Here, the vehicle includes various forms such as a motorcycle, a bicycle, and an automobile. Motorcycles that use fossil fuels to drive the engine are widely used because of their low cost, small size and low energy consumption.

In particular, interest in motorcycles with low energy consumption is increasing due to the recent rapid rise in oil prices and exhaustion of fossil fuels. Furthermore, the convenience of movement and storage that can be provided to the user through the motorcycle is presented as a solution to the severe traffic jam and parking space shortage in the urban area. However, unlike automobiles, the above-mentioned motorcycle is vulnerable to crimes such as theft by exposing the lock device to the outside. Conventionally, various methods have been proposed to prevent theft of the two-wheeler.

1, a conventional motorcycle locking device 100 includes a rotor 1, a cam body 2, a stopper 4, and a spring 3. The conventional locking device 100 of the motorcycle is started when the key K is inserted into the rotor 1 and the key K is rotated from the locked position to the starting position when the engine is started. After that, the key K is rotated in the opposite direction and is driven so as to be able to operate at the traveling position.

When the engine is stopped, the key is rotated from the travel position to the lock position. At this time, the projecting portion of the cam body 2 is caught by one end of the stopper 4 to stop the rotation of the key, and when the key K is rotated with the rotor 1 held in this state, The projection passes through the tip of the stopper 4 and is pivoted to the lock position to fix the handle.

However, the locking device 100 of the conventional motorcycle uses a stopper 4 connected to the spring 3 to control the rotatable state and the fixed state of the cam body 1, There is a problem that it is not only complicated but also frequently causes a malfunction due to frequent failures.

In addition, when the key is released from the rotor 1 due to vibration or user error during driving, the steering wheel is fixed and the driving direction can not be adjusted, resulting in a serious accident.

In recent years, a configuration has been proposed in which a locking function of the motorcycle not only performs start-up and handle locking but also provides a function of opening and closing a trunk for storing articles, thereby providing improved usability. However, in order to open and close the trunk, a separate shaft member is needed in addition to the shaft member that performs the starting and the steering wheel lock, so that the number of parts increases. As a result, the production process and production cost are increased, There was a problem.
