Description

[Detailed description of the invention] <Industrial application field> The present invention relates to an easy-to-install automobile door structure that can provide a wide space for getting in and out of the vehicle on the sides of the vehicle with a small amount of rotation at the beginning of the opening of the door. .

<Conventional technology> A step for getting on and off is provided below the front end of the door opening.
If a vehicle such as a truck whose front end of the door is hinged to the door opening of the vehicle body is parked close to a wall in a narrow space such as a warehouse, the front edge of the door ( There is not enough opening width or space for getting in and out (around the door hinge). Particularly in vehicles such as cab-over type trucks, where the floor of the driver's seat is quite high from the ground, and which is equipped with a step for getting in and out below the front end of the door opening as described above, if the door is not opened considerably, the driver's seat will be near the step. Because there is no space between the two, the driver cannot even put his feet on the steps when getting on and off the vehicle, making it extremely difficult to get on and off the vehicle.

Therefore, as a support device for automobile doors, Jitsukaisho
As disclosed in Publication No. 48-6718, two types of links of different lengths, namely short links and long links, are arranged in the longitudinal direction of the automobile, and are arranged near the center of the door and near the front end of the door opening of the vehicle body. It has been proposed that the door is supported on the vehicle body by connecting the two.

<Problems to be solved by the invention> However, the link described in the above-mentioned Utility Model Publication is long and connected to the center of the door and the front end of the door opening of the vehicle body, resulting in a large structure. It is inconvenient to get on and off the vehicle, and since two types of links are attached to the door and the vehicle body individually, assembly is difficult, and it is necessary to provide separate door stoppers for each.

The purpose of this invention is to have a large degree of freedom in door placement.
Another object of the present invention is to provide an automobile door structure that is easy to assemble to a vehicle body, does not require a separate stopper, and can provide a wide space for getting in and out with a slight rotation.

<Means for Solving the Problems> In order to achieve the above object, the door structure of the present invention includes a vehicle body side support plate and a door side support plate each having a U-shaped cross section that opens outward from the vehicle body when installed. In between, short and long connecting plates having flanges at both ends that sandwich the U-shaped cross section are rotatably connected to the vehicle body side and outside thereof, respectively, and the U-shaped cross section of the short connecting plate A door hinge with a door stopper formed on the vehicle body side end surface of the door that comes into contact with the vehicle body side support plate before the door is opened to its maximum extent, is attached to the vehicle body side support plate in the space between the front end of the door body and the vehicle body. The side support plates are attached to the front end of the door body.

<Operation> When the door D with the hinge attached is pushed open in the direction of the arrow X in FIG.
The long connecting plates 3 and 4 are connected to the vehicle body side support plate 1, respectively.
Rotates at different radii around pins 5 and 6 of
The door D is moved as shown in FIG. 3B and C via the door support plate 2 attached with the pins 7 and 8, respectively.

In this movement, the front end of the door D is rotated while moving away from the vehicle body B, so the door as a whole moves away from the vehicle body B to the side, and at an early stage when the door is opened, the side wall surface of the vehicle body and the door D are rotated. A wide space for getting on and off is created between the two. Therefore, the occupant of the vehicle can easily step on the step, and even in places where both sides are narrow, it is possible to get in and out of the vehicle by lying on one's side.

<Example> To explain the embodiment of the present invention using the drawings, first, the door hinge used in the door structure of the vehicle of the present invention is attached near the front end of the door opening O of the vehicle body B, as shown in FIGS. 1 and 2. A vehicle body side support plate 1 made of a plate material having a U-shaped cross section 1a to be attached, a door side support plate 2 having a U-shaped cross section 2a to be attached to the front end surface D' of the main body d of the door D, and the above-mentioned both ends. A short connecting plate 3 and a long connecting plate 4 each having flange portions 3a, 4a sandwiching the U-shaped cross-sectional portions 1a, 2a of the support plates 1, 2, and having U-shaped cross-sectional portions 3b, 4b formed in the middle. When the above-mentioned support plates 1 and 2 are attached to the vehicle body and door, the short connection plate 3 is arranged on the side facing the vehicle body, and the long connection plate 4 is arranged on the outside thereof. It is rotatably mounted by pins 5, 6, 7, and 8 set in the U-shaped cross sections 1a and 2a of the plates 1 and 2. At this time, for example, the long The connecting plate 4 is bent in the middle so as to avoid the end of the short connecting plate 3. Further, the end surface 3c on the vehicle body side of the U-shaped cross-section 3b of the short connecting plate 3 has a shape that reaches the maximum opening of the door D. A door stopper is formed which abuts near one end of the vehicle body side support plate 1 in front of the vehicle body.

The door hinge with the above structure is attached to the upper and lower parts of the door D, as shown in FIG. Door D with the above-mentioned hinge installed
If you push it open in the direction of arrow The door D is rotated, and the door D is moved as shown in FIG. In this movement, the door D does not simply rotate, but rotates while moving the front end of the door D away from the vehicle body B. This causes the door as a whole to move away from the vehicle body B to the side, making it easier to open the door. At this time, a space for getting in and out is created between the side wall surface of the vehicle body and the door D, which is wider than that of a conventional door supported by a single shaft. Therefore, the occupant of the vehicle can easily step on the step, and even in places where both sides are narrow, it is possible to get in and out of the vehicle by lying on one's side.

<Effects of the invention> As described above, the present invention provides a flange portion that sandwiches the U-shaped cross section between the vehicle body side support plate and the door side support plate, each of which has a U-shaped cross section that opens outward from the vehicle body when installed. A short connecting plate and a long connecting plate at each end are rotatably connected to the vehicle body side and the outside thereof, respectively, and the U-shaped cross section of the short connecting plate is attached to the vehicle body side end surface before the door is opened to the maximum. In the space between the front end of the door body and the vehicle body, a door hinge formed with a door stopper that comes into contact with the vehicle body side support plate is attached to the vehicle body and the door side support plate to the front end of the door body, respectively. Therefore, the following effects are obtained.

(1) Short and long connecting plates each having a flange portion on both ends that sandwich the U-shaped cross section between the vehicle body side support plate and the door side support plate, each having a U-shaped cross section that opens outwards from the vehicle body when installed. By using hinges that are pivotably connected to the vehicle body side and the outside thereof, respectively, the door is moved away from the vehicle body B as a whole to the side when the door is opened, and the vehicle body is A wider space for getting in and out can be created between the side wall surface and the door D than in a conventional door supported by a single axis, and the vehicle occupant can easily step on the step.
Even in places where both sides are narrow, it is possible to get on and off by lying on your side.

(2) Short and long connecting plates each having a flange portion on both ends that sandwich the U-shaped cross section between the vehicle body side support plate and the door side support plate, each having a U-shaped cross section that opens outward from the vehicle body when installed. Door hinges are rotatably connected to the vehicle body side and outside, respectively, and are compact, highly rigid, and easy to assemble, allowing for greater freedom in door arrangement, as well as high rigidity near the door hinges. A door structure that is easy to assemble with the vehicle body can be obtained.
