Description

  The present invention relates to a van type truck, and more particularly to a van type truck having a solar panel mounted on the upper surface of a packing box.

  This type of van type truck is known to have an opening / closing mechanism that secures a carry-in space such as a forklift when the wing provided in the cargo box is opened and allows cargo to be loaded up to the ceiling of the cargo box. (See, for example, Patent Document 1).

Japanese Patent Laid-Open No. 8-216691

In recent years, van-type trucks equipped with hybrid technology have been put into practical use in order to significantly reduce carbon dioxide (CO2) emissions compared to diesel trucks and achieve low fuel consumption, and electric vehicles are also practical for small trucks. It has become.
In particular, a van type truck with a large loading capacity has a long cargo box in the vehicle length direction, so a solar panel (solar cell panel) is placed on the top panel of this cargo box, and is always illuminated by sunlight while the truck is running. It is conceivable that the power generated by the solar panel is converted into energy related to vehicle driving or stored by effectively utilizing the upper surface space of the packing box.

  On the other hand, the double opening wing of the conventional packing box is composed of two wings each having an L-shaped cross section, which is formed by dividing the top panel of the packing box and comprising the divided top panel and the side panel of the packing box. The packing box is opened by rotating the wings while raising the lower ends of the side panels of the wings upward with the support portion provided at the divided portion of the top panel of the packing box as a base point.

  In the open state of the packing box, each side panel is positioned horizontally, and the upper panel is divided at the divided portion and positioned facing the vertical direction. Therefore, during the cargo handling operation, the solar panel cannot directly receive the sunlight irradiated from above, and the solar panel cannot be placed on the above-mentioned divided portion. There is a problem that the area becomes small and efficient power generation and storage cannot be performed.

  In addition, the conventional wing of the conventional packing box has an L-shaped cross section, and the lower end of the side surface of the wing projects to the side of the packing box at a relatively low position during the opening and closing operation. In addition to ensuring safety, the cargo box may not be opened and closed when the cargo handling work area is narrow. In addition, there is also known a conventional packing box provided with a wing that is asymmetric in the vehicle width direction that can be opened from only one side of the side, but in this case, the lower end of the side of the wing is the side of the packing box. Since the bulge extends further to the side, it is necessary to secure a larger cargo handling work area. Accordingly, these conventional trucks impose a double burden on the workers engaged in the cargo handling work, ensuring the safety of the surroundings and securing the cargo handling work area where the wings can be opened and closed.

In particular, the conventional double wing requires double opening / closing of the wings on both sides of the packing box, which doubles the burden on the worker.
Further, since the conventional packing box described above requires a packing box opening / closing mechanism independent of the frame structure of the packing box, the structure of the packing box becomes complicated and the weight of the packing box increases.
In addition, the above-described conventional packing box is provided with a so-called tilt that surrounds the floor panel, and the side panel of the packing box is divided into a tilt and a side of the wing. A locking mechanism with the wing is provided. Projections such as this locking mechanism hinder advertising and other wrapping and painting processes on the side panels of the packing box, which in turn restricts the design of the packing box, and further, objects and people on the protruding parts while the vehicle is running Assuming the contact of, there is a risk of hindering safety.

Further, in order to ensure the strength of the packing box on the box body wall, the side surface of the packing box is generally often processed with irregularities, which also impairs the aesthetics of the packing box, This hindered the painting process and hindered the freedom of design of the packing box.
An object of the present invention is to enable efficient power generation and power storage by a solar panel placed on the top panel of a packing box, and to greatly reduce the burden on workers during loading and unloading work. The object is to provide a future-oriented van-type truck that has a lightweight structure, excellent design performance, and improved safety.

  In order to achieve the above object, a van type truck according to the present invention includes a cargo box that constitutes a first structure that forms a part of a box wall of a cargo compartment from an upper panel and left and right side panels, and an upper panel. The solar panel placed on the top and the first structure are raised to form a panel housing space between the cargo compartment and the top panel, and each side panel is lifted while being tilted inward of the panel housing space. , Moved to a position where the upper surface panel and the side panel overlap each other, forming a second structure in which the upper surface panel and each side panel overlap, and lowering the second structure to the vicinity of the cargo compartment Panel accommodating means for opening the box.

Preferably, each side panel is divided in the vehicle height direction, and the panel housing means rises while gradually tilting each divided panel toward the inner side of the panel housing space, and is close to and substantially parallel to the top panel. Then, the second structure is formed by sequentially moving to the overlapping position.
Preferably, the panel housing means rises while simultaneously tilting the side panels toward the inner side of the panel housing space, and simultaneously moves to a position overlapping in close proximity to and parallel to the top panel to form the second structure. To do.

Specifically, the panel accommodating means includes a guide rail formed on a frame constituting the framework of the cargo box, and a front and rear end portion of each side panel protruding in the vehicle length direction and engaged with the guide rail. It has a link mechanism consisting of joints.
Specifically, the link mechanism includes a flexible connecting member that connects each side panel in the vicinity of each upper end thereof, a pulley that spans the connecting member, and each side panel that is above the pulley. And a flexible traction member connected in the vicinity of the upper end of one of them.

  Preferably, the outer surface of each side panel is a flat surface.

According to the present invention, by providing the above-described panel housing means, the solar panel placed on the top panel of the packing box is prevented from being shaded even when the packing box is opened, and irradiated from above. Therefore, efficient power generation and power storage can be achieved even during cargo handling work.
In addition, by tilting each side panel while tilting it toward the inner side of the panel housing space, it is possible to prevent the bottom end of each side panel from protruding greatly to the side of the packing box at a low position during opening and closing of the packing box. Is done. Thereby, while the surroundings including a pedestrian can be secured during opening and closing of the cargo box, the cargo box can be opened and closed even when the cargo handling work area is narrowed. Therefore, the double burden on the worker, that is, ensuring the safety of the surroundings and securing the cargo handling work area where the packing box can be opened and closed is alleviated, and the burden on the worker during the cargo handling work can be greatly reduced.

  In addition, when each side panel is lifted while being tilted stepwise toward the inner side of the panel housing space by ascending each side panel divided in the vehicle height direction, the side panels are lifted while being tilted without being divided. In contrast, the overhang width at which the lower end of each side panel projects to the side of the packing box during opening and closing of the packing box can be further reduced. Thereby, the burden of ensuring the surrounding safety at the time of the worker's cargo handling work and securing the cargo handling work area can be further reduced.

In addition, each side panel is lifted while simultaneously tilting to the inner side of the panel housing space, and simultaneously moved to a position where it overlaps in close proximity to the top panel, thereby opening and closing work on both sides of the packing box at a time. Since it can be performed, it is possible to further reduce the burden on the worker during cargo handling work.
The panel housing means includes a guide rail formed on the frame constituting the framework of the packing box, and an engaging portion that protrudes from the front and rear ends of each side panel in the vehicle length direction and engages with the guide rail. It has the link mechanism which becomes. Thereby, since the panel accommodating means can be formed using the frame structure of the packing box, the structure of the packing box can be simplified and the weight thereof can be reduced.

  The link mechanism includes a flexible connecting member that connects each side panel in the vicinity of each upper end portion, a pulley on which the connecting member is bridged, and the upper end portion of any one of the side panels above the pulley. And a flexible traction member to be connected. As a result, by pulling the towing member from either side of each side panel, the opening and closing work on both sides of the cargo box can be performed on either side of each side panel, so that when the worker is handling cargo Can be further reduced.

  Further, by forming the panel accommodating means using the frame structure of the packing box, the rigidity as the box body including the opening and closing mechanism of the packing box is mainly secured by the frame structure, and the outer surface of each side panel is for reinforcement. It is not necessary to provide irregularities. Further, by forming the panel accommodating means having the link mechanism described above, it is not necessary to provide a protrusion such as a lock mechanism on the outer surface of each side panel, so that the outer surface of each side panel can be made flat. is there. Thereby, lapping processing such as advertisements and painting processing can be easily performed on each side panel while enhancing the aesthetics, and the side surface of the highly safe packing box with less unevenness can be formed. Therefore, it is possible to increase both the degree of freedom of design and safety of the packing box.
