Description

[0001] DESCRIPTION [0002] DOOR RATCH IMPROBING HANDLING FEELING OF DOOR [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a door latch having improved door operation feeling for improving the operational feeling when a door of a vehicle is opened.

The vehicle is equipped with a door that opens when a passenger gets on and off.

When the passenger operates the handle 1 installed on the door at the time of getting on and off, the operating force F transmitted to the door handle 1 is transmitted to the door And is delivered to the locking door latch.

When the operation force is transmitted to the door latch, the operation force causes the pawl 110 to rotate, and the door is released from the claw 120 keeping the door in the locked state. The pawl 110 which is restraining the rotation of the claw 120 rotates and moves away from the claw 120 so that the claw 120 rotates to open the door.

However, the door latch of the related art as described above has a feeling that the door is torn when the handle 1 is operated.

That is, when the handle of the door is operated, the contact area between the contact surface 121 of the claw 120 and the contact surface 111 of the pawl 110 is minimum The frictional force is concentrated on the contact portion between the claw 120 and the pawl 110 and acts as a tear feeling when the claw 120 is released to cause a feeling of rejection from the occupant. That is, when the claw 120 suddenly increases the pulling force of the door immediately before the release, the door opens as if the door is opened when the door is released. As a result, the passenger feels rejection.

In recent years, the reaction force of the weather strip has been increased to improve the performance of NVH (noise, vibration, harshness) and improve the door opening / closing sound around the advanced car. This is because the frictional force between the claw 120 and the pole 110 Increases the sense of snatching increases.

Such a cut-off feeling does not affect the running performance, the fuel consumption, or the exhaust gas reduction of the vehicle, but is a factor that deteriorates the emotional quality of the vehicle.

On the other hand, the following prior art document discloses a technique relating to a 'door lock device for a vehicle'.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a door latch according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

A door latch having improved door operation feeling according to the present invention includes a pawl (10) provided on a door to rotate according to a manipulation of a door handle, and a pawl (10) which releases the locked state of the door when the pawl A door latch comprising a claw (20), wherein friction between the claw (20) and the pawl (10) to reduce friction between the claw (20) and the pawl Abatement means is installed.

The basic structure of the claw 20 for performing the locking and unlocking of the door in the door of the vehicle and the pawl 10 for operating the claw 20 is well known in the art and will not be described here.

In the door latch having improved door operation feeling according to the present invention, friction between the claw 20 and the pawl 10 is removed from the claw 20, So that the so called tearing feeling is removed when the door is opened.

The claw 20 performs locking and unlocking of the door by rotation. The claw 20 is installed on the door so as to be rotatable about a rotation axis. The claw 20 is locked when the scraper is fixed to the door by rotation, and when the claw 20 is detached from the striker, the door is unlocked.

When the door handle (1) is operated, the pawl (10) is rotatably installed on the door by the operation force of operating the pawl (10). The portion where the pole 10 contacts the roller 23 becomes the contact surface 11.

The pawl 10 prevents the claw 20 from rotating when the door is locked, thereby preventing the claw 20 from unlocking the door. In addition, the pawl 10 is separated from the cowl 20 by a lock release of the door, thereby allowing the cowl 20 to be in a rotatable state, thereby unlocking the door.

At this time, a friction reducing means for reducing the friction between the claw 20 and the pawl 10 is provided at a portion where the claw 20 and the pawl 10 are in contact with each other.

As a specific example of the friction reducing means, a roller 23 provided at the end of the claw 20 may be mentioned.

That is, a roller 23 is provided at a portion of the claw 20 that is in contact with the pawl 10, thereby removing the frictional force acting between the claw 20 and the pawl 10. [

The roller 23 is installed in the claw 20 at a position where the claw 20 and the pawl 10 are in contact with each other.

The roller 23 is formed as a contact surface of the claw in the prior art. The contact surface is removed, and a roller mounting groove 21 is formed in the roller mounting groove 21, So that the roller 23 is rotatably installed.

Particularly, the roller 23 is located inside the roller installation groove 21 and is provided so as to penetrate the rotation shaft 24 of the roller 23 at a portion extending from the surface of the claw 20, The roller 23 is rotatably installed at the end of the roller 20.

In the prior art, a large frictional force acts between the claw and the pawl because the claw and the pawl are in surface contact with each other. However, in the present invention, by providing the roller 23 on the claw 20 side, the frictional force is removed .

The operation of the door latch having the above-described configuration with improved door operation feeling according to the present invention will be described.

When the door handle 1 is operated to open the door of the vehicle, the pawl 10 is rotated by the operating force.

For example, in FIGS. 6 to 8, the pole 10 is shown rotated clockwise.

6), until the contact surface 11 of the pawl 10 is separated from the roller 23, the claw 20 is pushed by the pawl 10 Since the rotation is inhibited, the lock state of the door is maintained.

The contact surface 11 of the pawl 10 is rotated in a direction in which the contact surface 11 is separated from the roller 23 while the pawl 10 rotates and the friction between the contact surface 11 and the roller 23 , The roller 23 rotates (see Fig. 7).

At this time, only frictional force for rotating the roller 23 is applied between the contact surface 11 of the pawl 10 and the roller 23, so that a force acting between the claw 20 and the pawl 10 Frictional force is minimal.

8, when the pawl 10 continues to rotate and is disengaged from the roller 23, the pawl 10 no longer restrains the claw 20, so that the claw 20 Is rotated clockwise in Fig. 8, the door is unlocked to open the door.

In the present invention, by removing the frictional force acting between the claw 20 and the pawl 10 through the roller 23, a so-called sense of touch that the user feels when opening the door is removed, thereby improving the sensibility of the vehicle.
