Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge device for a trunk lid which supports a trunk lid at a front end of the trunk lid via a four-bar linkage so as to be freely opened and closed.

[0002]

2. Description of the Related Art Conventionally, as a hinge device of this type, as disclosed in Japanese Utility Model Laid-Open Publication No. Sho 60-49077, a pair of front and rear links are provided on the lower surface of a front edge of a trunk opening of a vehicle body at a connecting joint at an upper end thereof. The two links are pivotally attached to a hinge arm extending below the front edge from the front end of the trunk lid at a connection node at the lower end thereof, and the trunk lid is pivoted rearward while swinging the two links rearward. It is known to open the door. In this case, a stopper is attached to the rear link so as to abut on the lower surface of the front edge near the trunk opening when the trunk lid is fully opened, so that the trunk lid can be restrained at the fully opened position.

[0003]

In the above device, a four-joint link mechanism for hinges comprising a hinge arm and a pair of front and rear links is provided below the front edge of the trunk opening. There is a problem that the height dimension decreases.

In view of the above points, the present invention has a simple structure in which a large effective height in the trunk room is ensured and the trunk lid can be reliably stopped at the fully closed position and the fully opened position. It is an object of the present invention to provide a hinge device of a joint mechanism.

[0005]

In order to achieve the above object,
The present invention comprises a pair of long and short links having a front connection node pivotally connected to the trunk lid and a rear connection node pivotally connected to the vehicle body, and connects the rear link connection node of the short link to the long link. The link is located forward of the connecting node at the rear end, so that the two links are raised rearward and upward from a substantially horizontal falling posture when the trunk lid is opened, and abut on the front end of the trunk lid when fully closed. In addition, a stopper member that comes into contact with the long link when fully opened is attached.

[0006]

When the trunk lid is opened, the pair of long and short links rises rearward and upward, and the trunk lid is lifted upward and rearward, and the short link swings at an angle larger than that of the long link. The link at the front end of the short link is the point of force and the link at the front end of the long link is the fulcrum.The stopper is attached to the trunk lid at the fully open position, and the stopper attached to the trunk lid contacts the long link to further tilt the trunk lid. Is stopped, and the trunk lid is stopped at the fully open position.

[0007] On the other hand, when the trunk lid is fully closed, both links are in a substantially horizontal lying posture, and the amount of downward extension of the link mechanism with respect to the trunk lid is reduced as much as possible.
A large effective height in the trunk room is secured.
By the way, when both links fall substantially horizontally, the load acting on the front end of the trunk lid cannot be supported by the link mechanism. In this state, the lower surface of the front edge of the trunk lid is strongly pressed against the seal member attached to the trunk opening edge. According to the present invention, since the stopper member comes into contact with the vehicle body when fully closed, the load of the trunk lid is received by the vehicle body via the stopper member, and the seal member is attached to the trunk opening edge. The trunk lid is stopped in the fully closed position without applying excessive force to the members.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, reference numeral 1 denotes a vehicle body, and 2 denotes a trunk lid. The trunk lid 2 is supported on the vehicle body 1 on both sides of its front end via a four-joint link mechanism 3 so as to be freely opened and closed.

The link mechanism 3 is, as clearly shown in FIG.
It is composed of a pair of long and short links 4 and 5, and each link 4 and 5
Is connected to a downwardly bent lug 6a formed on a bracket 6 fixed to the lower surface of the front end of the trunk lid 2 by a connecting node 4 at the front end.
a and 5a, and at the rear end connecting sections 4b and 5b to the trunk opening side edge of the vehicle body 1.
Here, the connecting section 5b at the rear end of the short link 5 is located forward of the connecting section 4b at the rear end of the long link 4, and the front end of the short link 5 is provided on the outer front surface of the ear piece 6a. And a long link 4 on the rear inner surface of the ear piece 6a.
And the link 4a at the front end is provided so that when the trunk lid 2 is fully closed, both the links 4, 5 are tilted to a substantially horizontal lying posture.

When the trunk lid 2 is opened, the links 4 and 5 stand upright from the lying down position to raise the front end of the trunk lid 2 rearward and upward, and the short link 5 has a larger angle than the long link 4. , The orbital link 5a at the front end of the short link revolves around the orbital joint 4a at the front end of the long link 4, and the connecting node 5a exerts a force on the connecting node 4a.
The trunk lid 2 is tilted rearward with the
The trunk lid 2 is opened from the fully closed position indicated by A in the drawing to the fully opened position indicated by D via the states indicated by B and C. According to this, even in a vehicle in which the lower window center portion of the rear window projects greatly in the shape of an arch rearward, the trunk lid 2 can be greatly opened without causing interference with the rear window glass.

The bracket 6 has a trunk lid 2
When the trunk lid 2 is fully opened, a rubber stopper member 7 that abuts on the vehicle body 1 at a position forward of the connecting node 4a at the front end of the long link 4 is fixed.
The stopper member 7 is brought into contact with the long link 4 from the front thereof by tilting the trunk lid 2 with the fulcrum as a fulcrum,
Thus, the trunk lid 2 can be restricted between the fully closed position and the fully opened position by the stopper member 7.

[0012]

As is apparent from the above description, according to the present invention, the length of the four-bar linkage supporting the trunk lid, which extends downward, is reduced, and the effective height in the trunk room is increased. In addition, the trunk lid can be restrained between the fully closed position and the fully opened position, and this restraint is provided by a common stopper member, which has an effect that the structure is simplified and the cost is reduced.
