Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a hood support structure for an automobile with a hood.

[Conventional technology]

Many four-wheel drive vehicles for off-road driving are equipped with a canopy to cover the cargo bed behind the passenger compartment. Such a vehicle is provided with a portal-shaped hood frame whose base ends of both legs are rotatably supported in the longitudinal direction of the vehicle body between the central part or the rear end of both side frames of the cargo bed in the longitudinal direction of the vehicle body. The hood is
It is configured to cover the cargo platform in a box shape with the rear corner portion supported by a horizontal shaft portion extending in the vehicle width direction at the upper portion between the legs of the top bone. In addition, when fixing the top to the vehicle body, usually the middle part of the top is fixed in advance to the horizontal axis in the vehicle width direction of the top rib so that the top has a box shape, and the hem part of the top is fixed in advance. This is done by hooking it to the vehicle body. In other words, the front hem of the hood in the longitudinal direction of the vehicle body is connected to the gate-shaped roll bar that separates the cargo bed from the passenger compartment, the hem portions on both sides are connected to the frames on both sides of the cargo bed, and the rear hem are each hooked to the rear frame of the cargo bed. However, when attaching the top to the car body by hooking the top as described above, there is inevitably a gap between the unhooked part of the bottom of the top and the car body, so when the top is in use, the top and the car body are separated. There was a problem that the watertightness between the two was very poor. In particular, there was a significant problem at the connection between the front hem of the hood, which is fixed with the hem facing forward in the longitudinal direction of the vehicle, and the rear edge of the roll bar. In order to solve the above-mentioned problem, the applicant of the present application has added to the above-mentioned portal-shaped rear hood, in which the proximal ends of both legs are rotatably supported in the longitudinally intermediate portions of both side frames of the cargo platform.
A standing posture in close contact with the rear edge of the roll bar of the loading platform,
It is equipped with a gate-shaped front hood rib that is rotatably supported so that it can take a backward tilting position that leans down along the upper surface of both side frames of the cargo bed. We have proposed a canopy support structure in which the upper rear corner is supported and the front of the canopy is watertightly secured to the front canopy bone (Japanese Patent Application No. 62-22771). In the above proposed canopy support structure, the front canopy is attached to the other end of the link arm of a predetermined length, which is connected at its proximal end to link brackets fixed on both side frames of the loading platform so as to be rotatable in the front and back direction. The base end of the leg of the front hood bone is connected so as to be rotatable in the front-rear direction, so that it is rotatably supported in the front-rear direction with respect to the vehicle body. Due to this link mechanism, between the rotation fulcrum of the roll bar and the link bracket, the front hood bone moves linearly diagonally downward and connects to the roll bar as the link arm tilts forward and rotates. On the other hand, it is designed so that it can take the above-mentioned standing posture. This link mechanism prevents damage to the seal structure between the rear edge of the roll bar and the front hood bone due to repeated rotation of the front hood bone. The above proposed canopy support structure improves the watertightness between the canopy and the roll bar when the canopy is in use, and completely prevents rainwater from entering.

[Problem that the invention attempts to solve]

However, in the front canopy of the canopy support structure according to the above application, the canopy is fixed in a watertight manner,
Furthermore, when the top is attached, it must be directly rotated, and when the top is in use, it must be able to overcome the tension of the top and be fixed to the roll bar in a watertight manner. For this reason, the anterior hood bone is
It needs to be stronger than the rear hood bone, and its support structure is also required to be strong. The link arm in the front canopy support structure is rotatably supported by a link bracket fixed on the side frame of the cargo bed, and in the upright position when the top is in use and in the rearward tilted position when the top is stored. Take a leaning position along both side frames of the loading platform. In the above application, in order to rotatably support this link arm, it has a support shaft in the vehicle width direction, which is commonly used, and this support shaft can be rotated by a support wall in the longitudinal direction of the vehicle body. Adopted a link bracket to support it. However, due to lack of strength, the rotation of the canopy bone is unstable when attaching and removing the canopy, and the link arm is not fixed enough when using and storing the canopy, causing the canopy rib to wobble. It turned out that there was an additional issue that needed to be solved. The present invention was devised in view of the above-mentioned circumstances, and it solves the above problems and stabilizes the rotation of the canopy bone by firmly supporting the link arm, and when the canopy is in use. Another object of the present invention is to provide a canopy support structure that can prevent the canopy from rattling during storage.

[Means to solve the problem]

In order to solve the above problems, the present invention has the following features:
The following technical measures have been taken: That is, in the present invention, the front edge and rear corner portions are supported by portal-shaped front hood bones and rear hood bones that are provided on both side frames of the cargo platform behind the roll bar so as to be rotatable in the longitudinal direction of the vehicle body. In a vehicle with a hood, the vehicle is configured such that when the front hood rib is erected along the rear edge of the roll bar, the cargo platform is covered in a box shape by the hood, the front hood rib is constructed by connecting the base ends of the legs so as to be rotatable in the front and back directions to the tips of link arms of a predetermined length, which are connected at the base ends so as to be rotatable in the front and back directions, to the brackets mounted on the side frames of the loading platform. The bracket is characterized in that it is provided with left and right guide walls that are respectively formed to protrude upwardly so as to sandwich the link arm in a tight-fitting manner from both the left and right sides when the link arm assumes the tilted position.

[Functions and effects of the idea]

The link bracket in the canopy support structure of the present invention not only has a support wall for supporting the link shaft like the conventional one, but also has a support wall that supports the link arm from side to side when the link arm assumes the forward and backward tilted position. Left and right guide walls are respectively formed to protrude upward from both sides so as to tightly fit between them. In the posture where the front hood bone stands up when using the hood,
The arm part of the link arm that assumes the forward tilting position is firmly fixed by tightly fitting between the left and right guide walls in front of the link shaft from both the left and right sides. Even in the rearward tilted position, the arm portion of the link arm in the rearward tilted position is similarly tightly fitted and firmly fixed between the left and right guide walls at the rear of the link shaft from both the left and right sides. This can prevent the canopy ribs from wobbling when the canopy is used and stored. Furthermore, the guide wall not only has the function of fixing the link arm of the canopy bone when using and storing the canopy as described above, but also has the function of fixing the link arm of the front canopy bone to the roll bar when the canopy is installed. It also has the function of guiding the rotation of the arm from both the left and right sides, stabilizing the rotation locus, and stabilizing the rotation of the canopy.
