Description

[Detailed description of the invention] This invention is a car body bracket to be attached to a car body,
This relates to an automobile door hinge that connects a door bracket to be attached to the door with a link, and its purpose is to make it easy and safe for people to get on and off when the door is opened.

Conventionally, general automobile door hinges are constructed so that the door bracket rotates around a fixed axis relative to the vehicle body bracket, so when the door is opened, the side edge of the door is attached. Go inside the room.

Particularly in modern cars, the upper parts of both sides of the car body are curved inward due to the car body design.In this way, when the car door is opened, the upper edge of the side part deeply digs into the passenger compartment, making it difficult to enter and exit the car. In addition, there is a risk of injuring people's heads when getting on and off the vehicle, especially at the rear door.

The purpose of this invention is to solve this problem, and the vehicle body bracket and the door bracket are connected and pivoted via a link so that the door bracket can be rotated with respect to the vehicle body bracket. , and by providing a guide mechanism in which the tip of the door bracket moves in a direction away from the pivot point of the vehicle body bracket when the door is rotated to open the door, the door can be installed by separating the side edge from the vehicle body and preventing the above-mentioned biting. This prevents passengers from getting on and off at the entrance and exits easily and safely.

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 shows an open state of a rear door D of a car attached to a car body B using the hinge 1 of the present invention as an upper hinge and a ball joint type hinge 10 as a lower hinge, and shows an edge of the rear door D on the car body side. rotates along a plane that forms part of a cone with the lower hinge 10 at its apex, and in the open state, the upper edge of the rear door D on the vehicle body side is spaced outward, so even if the iron part is curved inward. To make it easy and safe to get on and off at an entrance without getting wedged into a room even when the user is in a room.

In the embodiment shown in FIGS. 2 and 3, the hinge 1 of the present invention comprises a vehicle body bracket 2 to be attached to a vehicle body (pillar) B, and a door bracket 3 to be attached to a door D. Flange portion 21a, 21
A vehicle body bracket 2 having a U-shaped cross section and a door bracket 3 having a U-shaped cross section and having upper and lower flanges 31a and 31b are placed opposite each other and connected by upper and lower links 3a and 3b.

That is, the upper flange portions 21a and 31 of both brackets 2 and 3
A dogleg-shaped flat plate link 4a, 4b is inserted between the lower flange portions 21b, 31b, respectively, and one end of these is connected to the upper and lower flanges 21a, 21b of the vehicle body bracket.
21b, and the other end is pivotally connected to a shaft 6 that extends between the upper and lower flanges 31a and 31b of the door bracket, and both brackets 2 and 3 are attached to the link 4a.
, 4b, relative rotation is possible.

As shown in FIG. 2, the upper flange portion 3 of the door bracket 3
a is formed by bending the base portion to which the door D is attached into a hook shape, and is located between the two pivot points formed by the shafts 5 and 6, and an upper flange portion 213 of the vehicle body bracket facing the tip portion a. A pin 7 is provided between them, and the pin 7 is inserted into a guide groove 8 formed in the upper flange portion 21a.

The guide groove 8 extends in a direction away from the pin 5 from the position of the pin 7 in the door closed state at a position between the rear of the vehicle body B (rightward direction in FIG. 2) and the outward direction of the vehicle body B.

A stopper 221 is formed on the edge of the vehicle body bracket 2 to restrict rotation of the door bracket 3 in the closing direction.

The illustrated door hinge device uses the hinge of the present invention as an upper hinge and a ball joint type hinge as a lower hinge. Door bracket 12 and ball joint mechanism 1
It is a normal hinge connected by 3.

When the upper hinge 1 and the lower hinge 7 are installed, the axis 5 and axis 6 of the upper hinge 1 and the ball 14 of the lower hinge 10 are such that the extension line of the axis of the axis 5 and the axis of the axis 6 is the ball 14. They are placed at a position where they intersect at the center of the two.

Now, when opening a door connected to the vehicle body using the door hinge device, when the door D is operated in the opening direction from the door closed state shown in FIG. It revolves around the heart.

At this time, the tip of the upper flange portion 31 of the door bracket located between the shafts 5 and 6 is guided by the guide groove 8 and moves toward the rear and outside of the vehicle body with respect to the shaft 5 and away from the shaft 5.

As a result, the upper part of the edge of the vehicle body side of the door D moves away from the vehicle body and rotates along a conical surface with the center of the ball 14 of the lower hinge 10 as the apex. As shown in Figure 1, the entire door is inclined and its upper part is separated from the vehicle body, so that the upper part of the entrance/exit space is maintained wide.

And getting on and off can be done easily and safely.

In the above embodiment, the hinge of the present invention was used only for the upper hinge, but it is also possible to use the hinge of the present invention for both the upper and lower hinges. In this case, the door does not slope and the entire edge of the door is aligned with the vehicle body. Rotate further apart.

Further, the guide mechanism may be formed by any appropriate means other than the type in which a groove is formed.

As mentioned above, the door hinge of the present invention has an extremely simple structure in which a link is interposed between the vehicle body bracket and the door bracket, and a guide mechanism is provided at the tip of the vehicle body bracket. It is designed to operate without any restriction, and exhibits excellent practical effects, especially in the current vehicle shape where the upper part of the vehicle body is curved inward.
