Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a front body structure of a cab-over vehicle, and more particularly, to a front wiper mounting portion of a cab-over vehicle.

[0002]

[Prior Art]

 The front wiper of a cab-over vehicle is generally driven by a wiper arm driving device provided inside the vehicle, with the lower end of the wiper arm attached to the front panel of the cab-over vehicle from outside the vehicle.

By the way, the front portion of a cab-over vehicle, particularly the front wiper mounting portion, has conventionally been structured as follows. That is, as shown in FIG. 3, front windshield wipers 1A and 1B for wiping the windshield glass W are attached to the front panel P constituting the front portion of the cab-over vehicle at positions along the lower edge of the windshield glass W, respectively. There is. FIG. 4 is a sectional view of the main part taken along the line IV-IV in FIG. In the figure, the lower end portion of the wiper arm 11 of the front wiper 1B is reciprocally attached to a wiper pivot portion 12 attached to the front panel P. On the other hand, a wiper motor 21 that constitutes the wiper arm driving device 2 and a link mechanism 22 that transmits the rotation of the wiper motor 21 to the rotation shaft 13 of the wiper pivot portion 12 are provided in the vehicle interior. R is a reinforcement provided inside the vehicle and covers the wiper pivot portion 12. The wiper motor 21 is supported by a support means (not shown) such as a stay provided on the reinforcement R.

[0004]

[Problems to be solved by the device]

 In the conventional front body structure of the cab-over type vehicle having the above-mentioned structure, since the wiper motor 21 and the link mechanism 22 constituting the wiper arm drive device 2 are inside the vehicle compartment, there is a problem that these operating sounds are directly transmitted to the passenger. there were. Further, the wiper arm drive device 2 and its parts must be replaced from the inside of the vehicle, which is troublesome.

The present invention has been made in view of the above circumstances. In the front of a cab-over type vehicle, the operation noise of the wiper arm drive device can be locked out to the outside of the vehicle compartment, and the wiper arm drive device and parts thereof can be easily replaced. It is intended to provide a partial body structure.

[0006]

[Means for Solving the Problems]

 As shown in FIG. 1, the present invention provides a reinforcement R having an upper edge and a lower edge fixed to a front panel P at a rear portion of a front panel P of a cab-over type vehicle, and is partitioned from a vehicle compartment by the front panel P. While forming a space portion K for storing the wiper arm driving device 2 inside, a service hole S for storing the wiper arm driving device 2 in the space portion K from the outside of the vehicle is provided on the front panel P, and a service hole S is provided in the service hall S. Is provided with a lid L detachably covering the same.

[0007]

[Action]

 The wiper arm drive device 2 is housed in the space K formed by the front panel P and the reinforcement R and separated from the vehicle compartment, so that the operating noise can be locked out of the vehicle. Further, by providing the service hole S in the front panel P, the lid L provided in the service hole S can be removed, and the work of attaching and detaching the wiper arm drive device 2 and components can be easily performed from outside the vehicle.

[0008]

First Embodiment A front body structure of a cab-over type vehicle of this embodiment will be described in detail with reference to FIG. FIG. 1 is a sectional view of an essential part of a front vehicle body structure according to this embodiment. A reinforcement R is provided at a rear portion of the front panel P, and an upper end portion of the front panel P and an upper edge portion of the reinforcement R are joined to each other. The lower edge is joined.

Below the upper edge portion of the front panel P, a wiper pivot portion 12 that pivotally supports the lower end portion of the wiper arm 11 so as to reciprocate is attached. Below the mounting position of the wiper arm 11 on the front panel P, a service hole S having a predetermined size is provided so as to penetrate therethrough.

The reinforcement R has a substantially U-shaped cross section, and its lower edge portion is joined to the end portion of the front panel P along the lower edge of the service wheel S. A space portion K that is separated from the passenger compartment is formed by R and the passenger compartment. A wiper arm drive device 2 for driving the wiper arm 11 is stored in the space K from the outside of the vehicle.

The wiper arm drive device 2 includes a wiper motor 21 and a link mechanism 22 that transmits the drive of the wiper motor 21 to the rotary shaft 13 of the wiper pivot portion 12. The wiper motor 21 is fastened and fixed to the support body 3 attached to the reinforcement R. One end of a first pivot arm 221 constituting a link mechanism 22 is rotatably connected to the wiper motor 21, and the other end of the first pivot arm 221 is connected to a second pivot via a wiper link 222. The end of the second pivot arm 223 is connected to one end of the arm 223, and the other end of the second pivot arm 223 is connected to the rotary shaft 13 of the wiper pivot part 12.

The service hole S penetrating the front panel P is provided with a lid L which also serves as an ornament and which covers the service hole S detachably, and the outer surface of the lid L is substantially flush with the outer surface of the front panel P. Is becoming

According to the front body structure of the cab-over type vehicle of the first embodiment having the above structure, the wiper arm driving device 2 is provided in the space K formed by the front panel P and the reinforcement R being separated from the vehicle compartment. Since it is stored, its operating noise is blocked without being transmitted to the passenger compartment. When the wiper arm drive unit 2 needs to be replaced or repaired, the lid L can be removed and repaired or replaced from the service hole S. Good sex. Also, since the service hole S is normally covered with the lid L, it is possible to prevent rain, snow, etc. from entering the space K.

[0014]

[Embodiment 2] This embodiment will be described with reference to FIG. 2. In the front panel P, a service hole S is provided so as to extend above the mounting position of the wiper pivot portion 12. Similar to the first embodiment, the reinforcement R provided at the rear portion of the front panel P has its upper edge portion joined to the upper end portion of the front panel P and its lower end portion along the lower edge of the service hole S. It is joined to the end of the panel P.

The wiper arm drive device 2 is housed in a space K formed between the front panel P and the reinforcement R so as to be separated from the vehicle compartment, and is installed in the wiper arm 11 via the wiper pivot part 12. This is connected so that it can reciprocate. The wiper pivot part 12 is fixed to the reinforcement R by a support 31 provided inside the space K.

In normal times, the service hole S is covered with the lid L. The lid L has a through hole L1 at a position corresponding to the wiper pivot portion 12 fixed to the reinforcement R, and the tip of the rotary shaft 13 of the wiper pivot portion 12 projects from the lid L. The lower end of the wiper arm 11 is fastened to the tip of the rotary shaft 13 of the wiper pivot portion 12 protruding from the lid L with a nut 14.

The other structure of this embodiment is substantially the same as that of the first embodiment.

According to the front body structure of the cab-over type vehicle of the second embodiment having the above structure, the wiper arm drive device 2 is housed in the space K separated from the vehicle compartment, as in the first embodiment. Therefore, the operating noise is cut off from the passenger compartment.

Further, when the wiper drive device 2 is repaired or replaced, after loosening the nut 14 to remove the wiper arm 11, the lid L is removed, and the service hole S provided in the front panel P is used to repair or replace the vehicle from outside the vehicle. Can be done.

[0020]

[Effect of the device]

 According to the front body structure of the cab-over type vehicle of the present invention, it is possible to prevent the operating noise of the wiper arm drive device from entering the interior of the vehicle and to make the interior of the vehicle quiet, and to repair and replace the wiper arm drive. Etc. can be performed more easily from outside the vehicle.
