The technical field to which the design belongs and the prior art in the field

Automobiles are generally classified according to the style and structure of the body, and classified into sedan, limousine, coupe and wagon depending on the use, and according to the roof type, close body, hard top and soft top. According to the classification is classified into two doors (three doors), four doors (five doors).

According to the rear style of the car, it is classified into notch bag, hatch bag, and fast bag, and the boxes are classified into 1 box, 2 box, 3 box, and modified box (1.5 box, 2.5 box).

In addition, the body of the vehicle consists of a door (front / rear), an engine hood panel, a panda panel, a bumper, a pillar, a window, a roof panel, a mirror, a trunk, and the like.

First, the bumper is a shock absorber installed at the front and rear of the body to prevent obstacles from directly contacting the body, and the rounded iron plate for the fenders is called a panda panel.

The window may be a front window, a side window, a rear window, or the like.

The pillar refers to the pillar next to the window, the pillar between the windshield and the side window is called the front pillar, the pillar between the front and rear side windows is called the center pillar or the side pillar, and the pillar between the side window and the rear window is called the rear pillar. have.

The front pillar is also called an A pillar, the center pillar is a B pillar, and the rear pillar is also called a C pillar.

The engine hood panel refers to an opening / closing lid placed on an engine room, and is generally called a bonnet, and a classification according to the opening / closing method includes a front hinge type and a rear hinge type.

The roof panel is an English term for the roof of an automobile and is referred to as a saw in the United States.

The trunk is classified into a trunk room and a trunk lid. A lid for opening and closing the trunk room is called a trunk lid.

The parts that can be opened and closed by the ignition key of the car include the driver's door and the passenger seat door, the glove box, the fuel tank cap and the trunk lid. Each of these parts is equipped with a lock cylinder that matches the tumbler of the ignition key.

In addition, the frame that forms the skeleton of the car mainly uses a monocoque body, which is a frameless body, and most of today's cars adopt this structure.

Since the body is integrated with the chassis frame, it is not only lightweight but also has the advantage of absorbing shock energy during collision and collision accidents while driving a vehicle, and has a structure that can absorb and absorb external shocks to the whole body.

Since the chassis portion is directly mounted on the body, the riding comfort is lower than that of the frame structure, but recently, the development of suspension and engine mounting technology has been solved.

In addition, there is an advantage in that the interior floor can be lowered compared to the frame body, and such a monocoque body has a large front body / rear body / under body / side body. body).

The front body is attached to the engine, front wheel suspension, radiator, steering gear box, etc. and has a variety of rigidity, and also has a variety of functions to protect the driver and occupant in the car interior by absorbing the impact energy due to the collision in the event of a crash It is developed and commercially available.

The shape of the rear body varies depending on the shape of a sedan, hatchback, wagon, etc. according to the appearance of the vehicle.

The underbody is equipped with a rear suspension or a deceleration gear driving device, and plays an important role in that the body is rigid. As a countermeasure against the movement and vibration of a suspension, a member and a reinforcing material are attached.

The side body is called the side body of the automatic side, that is, the front door and the rear door surroundings, to minimize the deformation when the vehicle is overturned by an accident during the driving of the car, and each door to the interior of the car in the event of a side collision accident In order to prevent it from coming in, and durability by it, etc. are considered, and it is produced.

The inside handle 100 of the conventional door is fixed to the handle housing 120 is installed between the door inner panel 220 and the door trim 240, as shown in Figure 4, the handle housing 120 is a housing in the rear portion A fixture 180 is formed and fixedly installed to the door inner panel 220. A circular damper 300 is formed on a contact surface of the handle housing 120 and the handle knob 140 to reduce contact noise and impact generated when the handle knob 140 and the handle housing 120 come into contact with each other. However, such a conventional damper 300 is simply provided with a circular shape in the form of a thin plate, the handle knob 140 is not provided with an area to sufficiently absorb and mitigate noise as the contact is in contact with the continuous use of the door inside handle Due to the problem that the increase in contact noise and the impact caused by abrasion increases due to the inconvenience to the user.

[Technical Challenges to be Done]

The present invention provides a door inside handle for a vehicle having a noise prevention structure that can prevent the noise by reducing / suppressing the noise generated when operating the handle knob of the door inside handle, the present invention is a handle knob of the door inside handle It is achieved by providing a door inside handle for an automobile having a noise prevention structure by providing a cushioning damper in which a raised portion and a groove portion formed therebetween are continuously formed as a handle housing in surface contact with the handle housing.

[Configuration and Action of Design]

1 and 2 illustrate a door inside handle for an automobile having a noise preventing structure according to the present invention, and the inside handle 10 for a car door 20 having the noise preventing structure includes a door trim 22 and a door. It is coupled between the inner panel, the handle knob 14 is coupled to the front portion.

In addition, the handle housing 12 which is in surface contact with the handle knob 14 includes a plurality of raised portions 34 and a buffer damper 30 continuously formed with grooves 36 provided between the raised portions 34. Is coupled, the damping damper 30 is coupled to the handle housing 12 is formed integrally with the binding portion 32 in the rear portion,

The ridge 34 of the buffer damper 30 has at least five revisions, and the groove 36 has four revisions.

3 shows a buffer damper 310 of another embodiment according to the present invention, which is formed in an elliptical shape with a hollow portion 314 formed therein.

The buffer damper 310 has a binding portion 312 formed integrally with the rear portion and is coupled to the handle housing 12.

In other words, the damper 30 is formed by the handle housing 12 which is in surface contact with the handle knob 14 of the door inside handle 10, and the ridge 34 and the groove 36 formed therebetween are continuously formed. In this case, the buffer damper 30 deforms the bulge 34 upon contact with the handle knob 14 to absorb and mitigate the impact.

In addition, the buffer damper has an noise prevention structure characterized in that it is formed in an ellipse shape having a hollow portion 314 provided therein, so that the hollow portion 314 is deformed and restored at the same time as the impact with the handle knob 14. To absorb and mitigate shock.

[Effect of design]

With reference to Figure 2 will be described the effect of the present invention.

When the occupant pulls the handle knob 14 of the inside handle 10 to open the door 20 and releases the handle knob 14 again, the handle knob 14 returns the hinge to its original position with respect to the shaft and the handle housing ( 12), wherein the ridge 34 of the damper damper 30 is deformed by the contact shock, so that the shock is absorbed and alleviated so that noise is suppressed.

In addition, according to the damper damper 310, the impact of the contact of the handle knob 14 is deformed while the hollow part 314 is reduced to absorb absorption.

Therefore, the noise generated at each operation of the door inside handle 10 is absorbed by the buffer dampers 30 and 310 to be reduced.

Therefore, damage to the handle knob 14 and the handle housing 12 in contact therewith can be prevented and noise by use can be suppressed or prevented to provide convenience to the user.
