[Detailed description of the invention] (Field of industrial application) This invention relates to a front body structure of a cab-over type vehicle.

(Prior Art and its Problems) Conventionally, there is a structure shown in FIGS. 2 and 3 as a front body structure of a cab-over type vehicle.

In the figure, a windshield 53 is installed on a front panel 52 that constitutes the front part of a vehicle body 51, and a wiper arm 54 is installed on the upper edge of the front panel 52 to wipe off the windshield 53. A wiper blade 55 that comes into contact with the window glass 53 is provided at the tip of the wiper arm 54 . The main part of the mounting part of the wiper arm 54 is shown in FIG. 3. The lower end of the wiper arm 54 is connected to a wiper pivot 58 that protrudes forward from the front panel 52. By being rotated via the pivot arm 60 and wiper link 61 installed on the side, the wiper arm 54 is moved toward the windshield 5.
It has a structure that allows it to reciprocate along 3.

In the figure, 59 is a pivot cover that covers the tip of the wiper pivot 58, 57 is a reinforcement, and 56 is a sealing gasket.

In such a structure, the wiper pivot 58 protrudes to the front side of the front panel 52 and is exposed to the outside of the vehicle, which causes problems such as poor appearance from the front side of the vehicle body 51 and the generation of wind noise when the vehicle is running. The point was hot.

In order to solve such a problem, as shown in FIG. 4, a projecting portion 1a is formed on the front panel 1 constituting the front of the vehicle body 51 at a lower portion of the windshield 53, and this projecting portion 1a is formed to extend forward. Exit part 1
A cover member 2 is attached to the front end of the front panel 1 in an upwardly extending manner via an end rubber 3, and the exposed part of the wiper pivot 58 that protrudes forward from the upper end of the front panel 1 is covered by the cover member 2 in a concealed manner from the front. The front body structure has been devised. However, in such a structure, the pivot arm 60 and the wiper link 6 are located inside the front panel 1.
1st class is installed, so in order to repair these drive devices, it is necessary to go to the instrument panel on the inside of the vehicle,
It is necessary to remove the wiper link 61 etc. after removing parts such as the steering wheel, heater unit, brake master bag, etc. from the inside of the vehicle interior, and there is a problem that attaching and detaching the wiper link 61 etc. is very troublesome. Furthermore, since the front panel 1 is responsible for supporting the wiper pivot 58, there is a problem in terms of rigidity.

(Means for Solving the Problems) The present invention has been devised in view of the above-mentioned conventional problems, and aims to provide a strong front body structure for cab-over vehicles that allows easy attachment and detachment of wiper links, etc. The purpose and gist of the vehicle is to provide a front body structure in which a cover member that conceals the lower end of the wiper arm from the front is removably attached to the front panel that constitutes the front part of a cab-over type vehicle. A lower cover is provided behind the front panel to separate a wiper arm drive device connected to a lower end of the wiper arm from a vehicle interior, and a pivot stay for supporting the drive device is provided between the lower cover and the cover member. and forming an opening for introducing outside air in the pivot stay,
The wiper arm drive device can be attached and detached from the outside of the vehicle interior in front of the lower cover through the opening, and the lower cover is also formed with an opening that communicates with the interior of the vehicle, and the opening and the pivot stay are connected to each other. A drain pipe was installed at the bottom between the openings to drain rainwater to the outside of the vehicle.

(Function) A cover member that covers the lower end of the wiper arm is attached to the front panel.
The lower end of the wiper arm is hidden from the front side by the cover member and protruding parts such as the wiper pivot are not exposed to the front, so the appearance from the front side is improved, and the cover member prevents wind noise when driving. Improves aerodynamic performance, etc. Furthermore, by removing the cover member, the wiper link, etc. can be attached and detached through the outside air introduction opening of the pivot stay, so the wiper arm drive device can be attached and detached from the outside of the vehicle cabin in front of the lower cover through the opening, etc. This makes repair work, etc. extremely easy. Further, since the pivot stay is hidden from the outside by the cover member, the pivot stay can be formed to have a strong shape and thickness, and the supporting rigidity of the drive device such as the wiper pivot can be strengthened accordingly. Furthermore, since openings are provided in the pivot stay and lower cover, outside air can be taken into the vehicle interior through both openings, and both openings can be formed to have a large area.
Ventilation resistance when outside air flows in can be extremely reduced. Moreover, even when rainwater or the like flows in together with outside air, the rainwater or the like flows out of the vehicle through the drain pipe, so that it is possible to effectively prevent rainwater or the like from flowing into the vehicle interior.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In this example, a cover member 12 that covers the wiper pivot 58 protruding forward from the front is attached to the upper edge side of the front panel 11, and a lower cover 15 is further disposed on the interior side of the front panel 11. A pivot stay 14 is provided on the front side of the lower cover 15. The lower edge of the window glass 53 is joined to the joint between the upper end of the pivot stay 14 and the upper end of the lower cover 15 via a gasket 56, and between the pivot stay 14 and the lower cover 15 a pivot arm 60, which is a drive device for the wiper pivot 58, and a wiper link are connected. 61 has been installed.
Further, at the lower end of the pivot stay 14 there is a support panel 16 that is connected to the inside of the front panel 11.
is arranged, and a drain pipe 17 is joined to the lower end of the support panel 16 and the lower cover 15,
A drain hose 18 communicating with the outside of the vehicle is connected to the lower end of the drain pipe 17. Furthermore, a second air intake portion 15a communicating with the vehicle interior is opened in the lower cover 15, and the pivot stay 1
4 is also provided with a first intake portion 14a that communicates with the outside of the vehicle.

Therefore, in the structure of this example, since the cover member 12 is installed in front of the wiper pivot 58, the lower end of the wiper arm 54 is hidden from the front side, improving the appearance from the front side, and the lower cover 15 Since the pivot arm 60 and the wiper link 61 are separated from the inside of the vehicle, conventionally, when the wiper link 61, the pivot arm 60, etc. are to be attached or removed for repairs, etc., they are attached to the instrument panel, steering wheel, heater unit, etc. on the inside of the vehicle. It was necessary to remove parts such as the brake master bag from the interior of the vehicle before removing the wiper link 61 and the like from the interior of the vehicle, but in this example structure, the cover member 12
By removing the first pivot stay 14,
Wiper link 61 via intake part 14a
etc. can be attached and detached from the outside of the vehicle, which has the effect of making repair work extremely easy. Also, since the pivot stay 14 is hidden from the outside by the cover member 12, the pivot stay 14 has a strong shape and wall thickness. In this example, the pivot stay 14 and the lower cover 15 are provided with the first intake portion 14a and the second intake portion 15a. Since this is provided, outside air can be taken into the vehicle interior from above the cover member 12 through the first intake section 14a and the second intake section 15a, and an air conditioning unit etc. can be installed inside the vehicle interior of the second intake section 15a. If connected, the air conditioning in the vehicle interior can be controlled extremely well, and since the inflow of outside air can be done well through the first intake part 14a and the second intake part 15a, the inflow of outside air is more efficient than in the past. The ventilation resistance can be extremely reduced. In other words, in the past, intake holes for outside air were provided in the front of the headlamp case or front panel, so the opening area was not large enough, resulting in extremely large ventilation resistance, which caused problems such as insufficient wind power and spoiling the external appearance. However, in this example, the first intake part 14a and the second intake part 15a having large holes can be opened in the pivot stay 14 and the lower cover 15 that are hidden by the cover member 12, and the ventilation resistance can be reduced. At the same time, sufficient air volume can be obtained. Moreover, the external shape of the vehicle body seen from the front side is not impaired in any way. Note that when rainwater or the like flows in from the first intake portion 14a together with outside air, the rainwater or the like flows out of the vehicle through the drain pipe 17 and the drain hose 18, so that it is possible to effectively prevent rainwater or the like from flowing into the interior of the vehicle. It is something that can be done.

The wiper arm drive mechanism is connected to the lower end of the wiper arm. A lower cover is provided behind the front panel which separates the wiper arm drive mechanism from the vehicle interior. A pivot stay is provided between the lower cover and the cover member. An opening is formed in the pivot stay to introduce outside air. The wiper arm drive mechanism can be attached and detached from the vehicle interior through the opening. In addition, an opening communicating with the interior of the vehicle is formed in the lower cover, and a drain pipe for draining rainwater to the outside of the vehicle is disposed in a lower portion between the opening and the opening of the pivot stay, so that the lower end of the wiper arm is concealed from the front by the cover member and the protruding parts of the wiper pivot, etc. are not exposed forward, improving the appearance from the front side, and further, by removing the cover member, the wiper link, etc. can be attached and detached through the opening for introducing outside air in the pivot stay, so that the attachment and detachment of the wiper arm drive device can be performed from the outside of the vehicle through the opening, making repair work, etc., extremely easy. Also, since the pivot stay is concealed from the outside by the cover member, the pivot stay can be formed to have a strong shape and thickness, which increases the support rigidity of the drive device such as the wiper pivot. Furthermore, since openings are provided in the pivot stay and the lower cover, outside air can be taken into the vehicle cabin through both openings, and both openings can be formed to have a large area, which greatly reduces the ventilation resistance when outside air flows in. Moreover, even when rainwater or the like flows in together with the outside air, the rainwater or the like flows out through the drain pipe, which has the effect of effectively preventing the rainwater or the like from flowing into the vehicle interior.
