DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outside handle for a vehicle door, and more particularly to an automatic locking device for an outside handle of a vehicle door which is automatically maintained in a locked state in a side collision. .

[0002]

2. Description of the Related Art In an outside handle assembly of a vehicle door, as shown in FIG.
The levers 8 erected on both sides of the outside handle 6 are rotatably supported by hinges 10 on the support bases 4 erected on both sides of the upper part.

An elastic member 12 such as a torsion coil spring is installed on one side of the hinge shaft 10, and a free end on one side thereof is connected to a lever 8 on one side of the outside handle 6.
Is elastically supported by the upper end of the housing 2 and the other free end is elastically supported by the housing 2 so that the outside handle 6
Of the housing 2 is located in the recessed portion in the housing 2.

[0004] Therefore, when the driver or the passenger pulls up the outside handle 6 when the door is opened and the driver tries to board the vehicle, the outside handle 6 is moved to the hinge shaft 1.
By rotating around the zero and operating the outside handle rod, the locking state of the door latch is released and the door can be opened and closed.

[0005] The outside handle assembly for a vehicle door as described above includes locking means for preventing the door from opening in the event of a side collision, thereby ensuring the safety of the driver and the occupant. .

In the conventional locking means, a shock is applied to the door from the side by mounting a balance weight capable of maintaining the center of weight of the outside handle above the lever portion of the outside handle. In this case, the outside handle was arbitrarily rotated to prevent the door from opening.

[0007]

However, in the conventional locking means as described above, since the arbitrary rotation of the outside handle depends only on the balance weight, the rotation range becomes inaccurate, and the safety is ensured. There was a problem that can not be expected. In addition, there is a problem that a predetermined large space must be secured in consideration of the rotation in order to mount the balance weight.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a driver and a boarding vehicle which are automatically and securely maintained in a locking state in a side collision. It is an object of the present invention to provide an automatic locking device for an outside handle of a vehicle door in which safety of a person is secured and a space for mounting a locking means is minimized to increase a space utilization rate.

[0009]

In order to achieve the above object, an automatic locking device for an outside handle of a vehicle door according to the present invention is provided on a support stand provided on both upper sides of a housing. Lever provided on both sides is rotatably supported by a hinge shaft, and a vehicle having an elastic member provided on the hinge shaft for applying an elastic force for maintaining the outside handle in an initial state. An automatic locking device for an outside handle assembly of a door, comprising: a rotating member disposed at a predetermined position of the lever so as to rotate when a predetermined impact force is applied from a side surface; and a vicinity of the rotating member. And a locking portion that holds the rotating member when the rotating member rotates by a predetermined angle or more.

It is preferable that the rotating member has a tooth portion on an outer peripheral surface thereof and has a predetermined mass so that the rotating member can rotate when an impact force of a predetermined value or more is applied to the door.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of an automatic locking device for an outside handle of a vehicle door according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a rear view showing an outside handle assembly of a vehicle door to which the present invention is applied. In this outside handle assembly, a support is provided upright on both upper sides of a housing 2. Lever 8 erected on both sides of outside handle 6 on table 4 is rotatably supported by hinge shaft 10.

An elastic member 12 such as a torsion coil spring is installed on one side of the hinge shaft 10, and one free end of the elastic member 12 is connected to a lever 8 on one side of the outside handle 6.
Is elastically supported by the upper end of the housing 2 and the other free end is elastically supported by the housing 2 so that the outside handle 6
Of the housing 2 is located in the recessed portion in the housing 2. When the outside handle 6 is pulled up, the outside handle 6 rotates around the hinge shaft 10,
Activating the outside handle rod opens the door.

As shown in FIGS. 2 and 3, the outside handle assembly includes a lever 8 on one side and a support 4 supporting the lever 8 with a locking means. That is, the locking means according to the present invention includes a rotating member 14 having an upper end rotatably supported on one side of the intermediate portion of the lever 8, and holding the rotating member 14 when the rotating member 14 is rotated outward. A locking portion 16 for preventing the handle 6 from rotating arbitrarily.

The rotating member 14 has a fan shape having a predetermined mass, and has teeth 18 formed on the outer peripheral surface thereof. The mass of the rotating member 14 is set according to the operating range of the applied vehicle or the locking means. In a preferred embodiment, the impact force applied to the door is 2 to 5 G (2 to 5 × 9.8 k).
g / m / sec ² ). Of course, this numerical value is not limited to this, and can be largely changed according to the vehicle type and the required operating range.

An engaging portion 16 for holding the rotating member 14 when the rotating member is rotated is formed at a predetermined portion of the support base 4 corresponding to the rotating member when the rotating member is rotated. It can also be formed as a stop member. In the illustrated example, the locking portion 16 is formed as a tooth corresponding to the tooth portion 8 of the rotating member 14 on the inner surface of the support base 4 supporting the outside handle 6. Therefore, when the rotating member 14 rotates outside, that is, clockwise in the drawing, the rotating member 1
The fourth tooth portion 18 and the locking portion 16 are engaged.

At a position above the rotating member 14 of the lever 8, a restricting means for restricting the rotation of the rotating member 14 is formed. In the illustrated example, an arc-shaped projection 20 is provided as the limiting means. The arc-shaped projection 20 is for preventing reverse rotation of the rotating member 14 due to running vibration of the vehicle, and is formed of an elastic body so that its length can be adjusted as needed.

In the locking device of the present invention constructed as described above, in a normal state, as shown in FIG. 4, the rotating member 14 is maintained in a state of naturally hanging downward, so that the outside handle is provided. It does not act as any obstruction in operating the door 6 to open and close the door.

When a predetermined impact force is applied to the door due to a side collision in such a normal state, as shown in FIG. 5, the rotating member 14 having a predetermined mass is rotated clockwise by inertia, as shown in FIG. As shown in FIG. 6, the outside handle 6 rotates clockwise.

Then, the engagement of the teeth 18 of the rotating member 14 with the locking portions 16 of the support base 4 restricts the rotation of the outside handle 6 from being performed any more. Will not open. That is, when an impact is applied from the side, the rotation member 14 performs a role as a cradle, so that the rotation of the outside handle 6 can be prevented.

In the above-described operation process, the rotation of the rotating member 14 is limited by the arc-shaped projection 20 as a limiting means even when the impact force is large, and therefore, the rotating member 14 does not rotate completely. 18 can be easily engaged with the locking portion 16 and the connected state can be maintained firmly.

Further, when the vertical length of the rotating member 14 is set, it is preferable that the setting is made so that the outside handle 6 does not rotate more than 8 ° in consideration of the rotation range of the outside handle 6.

[0023]

As described above, according to the present invention,
The outside handle is automatically locked at the time of a side collision, and the locking state is maintained firmly, so that the safety of the driver and the occupant can be improved. Further, the operating range of the rotating member is small, and the mounting space thereof can be minimized.
