Description

{DOOR OPENING PREVENTION STRUCTURE BY INERTIAL FORCE}

The present invention relates to a structure for preventing a door from being opened by an inertia force, and more particularly, to a structure for preventing a door from being open when a side collision occurs in a vehicle.

Generally, when a door is opened in a side collision of a vehicle, the occupant is thrown out of the vehicle, resulting in further injury.

In consideration of this point, a problem that the door is opened when the side of the vehicle collides is solved by applying the balance weight capable of imparting the inertia resistance to the door out side handle.

Normally, when the vehicle collides with a side of the vehicle, the opening of the door causes the door outer side handle to be pulled by the inertia force generated at the time of the collision, thereby releasing the restraint of the slider.

To counter this problem, the balance weight is connected to the lever of the outside handle to prevent the opening of the outside handle due to the inertial force generated during the collision.

For example, an inside of the handle is provided with an outside handle lever rotatable about a hinge axis, and a balance weight is formed at the outside handle lever at this time.

Therefore, immediately after the collision of the vehicle side, the outside handle is pulled by the force directed toward the outside of the vehicle by the inertia force of the vehicle. When the outside handle is pulled by the inertia, the outside handle lever is rotated to open the door Occurs.

In consideration of this, the balance weight is mounted on the hinge axis of the outside handle lever to cancel the inertia force of the outside handle, thereby preventing the door from being opened.

Various apparatuses such as Korean Patent No. 10-0897693 and Korean Patent No. 10-0792931 disclose devices for preventing the door from being opened when a side collision occurs in a vehicle.

However, the conventional door opening prevention apparatus has the following disadvantages. Cost and weight are increased by unnecessary parts. That is, in the outside handle lever, the balance weight exists only to prevent the door from being opened during the side impulse, and it must have a size corresponding to the handle size (weight), thereby providing sufficient inertial force for preventing the door from being opened during a side collision. As a result, the burden of the cost and the weight becomes large.

In addition, there is a problem of newly producing and tuning the balance weight according to the development vehicle type. In other words, as the size and design of the steering wheel differ according to the type of vehicle, the balance weight should also be applied to various types of vehicles. Accordingly, various molds are manufactured for each vehicle type, and the test is repeated several times.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a structure for preventing a door from being opened when a vehicle collides with a side, and to provide a door opening prevention structure by a simple structure, a volume, and a low inertia force.

As described above, the door opening prevention structure by the inertia force according to the embodiment of the present invention has the structure that prevents the door from being opened due to the collision inertia force, and has a door handle arranged to be pulled by an external force, And a lever unit arranged to pull the door opening cable by rotating about the center pin, wherein the lever unit is arranged to rotate about the rotation center pin by the handle, and a torque transmission projection A first lever which is formed to be protruded, a second lever which is rotated around the rotation center pin and is arranged to pull the cable, and one end is rotatably fixed to one side of the second lever, Wherein when the first lever rotates, the rotation force transmitting projection causes the rotational force of the first lever to pass through the phase And the inertia pin transmits the rotation force of the first lever to the second lever when the inertia pin is rotated in the second lever by the collision inertia force and the other end is disengaged from the torque transmission projection, .

And an inertia pin elastic member elastically holding the rotational position of the inertial pin such that an inertial pin head formed at the other end of the inertial pin is disposed corresponding to the rotational force transmitting projection.

The inertia fin may be disposed in parallel with the rotation center pin in a state in which no collision inertial force is generated.

Wherein the inertia pin is vertically disposed at a predetermined distance from the rotation center pin, and the other end of the inertia pin is close to the rotation center pin And the fixing pin may pass through the inertia fin.

And a latching protrusion for pulling one side of the first lever so that the first lever rotates about the rotation center pin may protrude from one side of the handle.

One end surface of the inertia fin is formed with a spring groove to be engaged with the inertia pin elastic member, and the inertia pin elastic member can elastically stop the rotation of the inertia pin through the spring groove.

And an inertial pin housing having an inertial pin insertion groove for inserting the inertial pin in parallel with the rotation center pin is formed on the other side of the second lever, .

And an inertia pin elastic member that is engaged with the inertia pin housing and resiliently holds the rotational position of the inertial pin such that an inertial pin head formed at the other end of the inertia pin is disposed corresponding to the rotational force transmitting projection.

Wherein the inertia pin is vertically disposed at a predetermined distance from the rotation center pin, and the inertia pin head formed at the other end of the inertia pin is positioned at a predetermined distance from the rotation center pin, The stationary pin may pass through the inertial pin such that the stationary pin moves closer to or away from the rotational center pin.

According to the present invention for achieving such object, it is possible to prevent a passenger from bouncing out through a structure for preventing a door from being opened when a vehicle collides with a side, thereby improving stability.

In addition, the door opening prevention structure at the time of side collision has a relatively simple structure, and the weight is reduced, so that the degree of freedom of design of the vehicle can be improved.

Referring to FIG. 2, an inertial force is generated in the handle 100 when a side collision occurs in the vehicle, so that the handle 100 is pulled. The locking protrusion 107 pulls the first lever 105 to rotate the first lever 105 about the rotation center pin 110.

The inertia pin 115 receives the elastic force of the inertia pin elastic member 114 and rotates about the fixing pin 112 to rotate the first lever 105 and the second lever 120, The rotational force transmission path of the motor is interrupted.

Accordingly, the second lever 120 is not rotated, the cable 125 is not pulled, and the door is not opened in a locked state.
