Description

Grip handle buffer structure of car {STRUCTURE FOR DAMPING A GRIP HANDLE OF AN AUTOMOBILE}

The present invention relates to a grip handle buffer structure of an automobile.

Generally, as shown in FIG. 1, an inside handle 10 for opening a door is provided on a side door of a vehicle, and a grip handle 20 for promoting a passenger's body stability while driving. To raise.

Therefore, the occupant is to maintain the body stability in the state of holding the grip handle 20.

However, such a grip handle has the advantage of maintaining the body stability of the occupant while driving, while inherent in the fatal injury to the arm in the event of a crash.

That is, when a strong collision accident occurs during high-speed driving in a state where the occupant holds the grip handle 20, the occupant's body is biased in the advancing direction, and at the same time, the occupant grips the grip handle 20 with a strong force so as not to bias the occupant. Because of this, as well as lethal injury to the wrist by the mutual repulsive force, as well as causing problems such as severely broken shoulder bones.

The present invention was created in order to solve such a conventional problem, the grip handle of a vehicle that can prevent the injury to the wrist and shoulder bones by imparting a cushioning force to the grip handle that the occupant is holding during a strong collision accident The purpose is to provide a buffer structure.

In order to achieve the above object, the present invention, the grip handle consisting of a main grip protruding out of the door panel adjacent to the passenger seat, both ends are fixed to the door panel, and a sub grip is slidably installed inside the main grip. and; A first cushioning means interposed between the main grip and the sub grip, the first buffer means for attenuating an impact applied to the occupant's hand in the event of a collision; And a second cushioning means interposed between both ends of the main grip and the door panel to attenuate the impact secondarily.

Referring to FIG. 1 and as shown in FIGS. 2 to 4, the present invention is roughly divided into a grip handle 20 and first and second shock absorbing means 30 and 40.

The grip handle 20 is installed to protrude to the outside of the door panel 1 and is provided to be held by a passenger. In particular, the grip handle 20 is slidable along the inside of the main grip 21 and the main grip 21. It consists of a sub grip 22.

The first cushioning means 30 is provided in the grip handle 20 itself, that is, interposed between the main grip 21 and the sub grip 22 so that the sub grip 22 moves into the main grip 21. It is to give a cushioning force when sliding is conveyed.

In the detailed structure of the first shock absorbing means, a shock absorbing plate 31 is fixed to the inner side of the main grip 21, and the shock absorbing plate 31 has a predetermined radius of curvature along the traveling direction. It consists of the guide part 31a, the press part 31c in which the bellows type rib 31b was formed, and the engaging part 31d of a predetermined radius of curvature.

On the other hand, the hook 32 is provided on the outer surface of the sub grip 22, the hook 32 is initially seated on the guide portion 31a of the buffer plate 31, the pressing portion 31c at the time of collision It is seated on the locking portion 31d.

The second shock absorber 40 is provided between both ends of the main grip 21 and the door panel 1, that is, the door inner panel 2, and performs a function of attenuating the impact secondarily.

In the detailed structure of the second shock absorbing means 40, the shock absorbing member 41 is fixedly installed on the inner surface of the door inner panel 2 corresponding to both ends of the main grip 21.

As the shock absorbing member 41, a rubber or sponge having excellent shock absorption may be used.

In addition, the coupling protrusion 42 extends from both ends of the main grip 21 to penetrate and engage the door inner panel 2, and the coupling protrusion 42 is in contact with the side surface of the shock absorbing member 41.

Reference numeral 3 is a door outer panel, and 4 is a door trim.

According to the present invention configured as described above, when a crash occurs in a state where the occupant holds the grip handle 20, the occupant's body is biased in the direction of travel.

In this way, the hand holding the grip handle 20 by bias in the advancing direction is also exerted a force in the advancing direction. At this time, the shock is buffered through the first and second shock absorbing means 30 and 40 to injure the hand. Is prevented.

In more detail, an initial collision occurs, and the sub grip 22 slides inwardly of the main grip 21 to cushion the impact first.

That is, the hook 32 on the sub grip 22 presses the bellows type rib 31b while passing through the pressing portion 31c via the guide portion 31a of the buffer plate 31 in the main grip 21. Passed to obtain a buffer force and at the same time is caught by the locking portion (31d).

In this way, since the first shock is buffered, the sub grip 22 is engaged with the engaging portion 31c of the main grip 21, so that the force is applied in the advancing direction together, and at both ends of the main grip 21. The coupling protrusion 42 formed is in contact with the shock absorbing member 41 on the door inner panel 2 to thereby receive a second shock absorbing effect.

As described above, in the present invention, a collision accident occurs in a state where the occupant grips the grip handle, and a cushioning action between the main grip and the sub grip forming the grip handle, and a buffering action provided between the main grip and the cushioning member provided inside the door panel. Shock can be absorbed in the first and second order.

Therefore, a large force is not applied to the hand or shoulder of the occupant holding the grip handle, and thus, there is an advantage of preventing injury to the wrist and the shoulder blade.
