Description

DETAILED DESCRIPTION OF THE INVENTION <<Industrial Application Field>> The present invention relates to a front body structure of a cab-over type vehicle, and more particularly to a body structure of a lamp housing portion disposed on the side of the front part.

<<Prior Art>> As is well known, there is a so-called cab-over type vehicle body structure in which an engine is disposed at the front side of the vehicle body and a driver's seat is provided above the engine.

The front body structure of this model was developed in the 1980s, for example.
It is disclosed in Publication No. 9771.

As shown in the same issue, in this type of vehicle body structure, lamp housings are generally placed on the left and right edges of the front panel to form a recess that is open at the front. It houses lamps and vehicle side lights.

By the way, head lamps, blinker lamps,
Bulbs used in vehicle side lights usually have a limited lifespan, and the filament breaks around the end of the lifespan, rendering them unusable.

Furthermore, the filament may break due to vibrations caused by driving, etc., before reaching the end of its service life.

When a headlamp becomes unusable, it must be replaced, but there was a particular problem that only existed in cab-over type cars, where the headlamp bulb was replaced.

<<Problem to be solved by the invention>> In other words, when driving at night, the direction in which the headlights of automobiles illuminate the front is strictly set, so if the bulb burns out, it is possible to change the direction of illumination by replacing the entire headlamp. have to readjust,
Usually only the internal valve is replaced because it is difficult.

However, in cab-over type cars, there is no space on the back of the lamp housing for replacement work as in normal bonnet type cars, and the back side is spaced a little apart into the passenger compartment.

Therefore, if you want to convert a headlamp bulb, you must remove the floor mat inside the vehicle interior or the cover panel that covers the opening formed in the lamp housing. The work space was narrow due to equipment, seats, etc., making work from inside the vehicle extremely tedious.

This invention was made in view of the above-mentioned conventional problems, and its purpose is to provide a cab-over type headlamp that allows the headlamp bulb to be easily replaced from outside the vehicle body without any troublesome work. The purpose is to provide a front body structure for a car.

<<Means for Solving the Problems>> In order to achieve the above object, the present invention provides a front body structure for a cab-over type vehicle, in which a lamp housing disposed between a front panel and a front pillar is attached to the front pillar. The cross-sectional shape is approximately L-shaped, and includes a rear wall extending inward from the front edge of the rear wall, and a side wall extending from the inner end of the rear wall toward the front panel.

Further, a headlamp having a removably installed headlamp bulb is disposed in front of the rear wall of the lamp housing at a required distance from the rear wall.

Furthermore, a combination lamp including a turn signal lamp and a vehicle auxiliary lamp is removably provided between the headlamp and the front pillar.

<<Function>> With the front body structure of a cab-over type vehicle configured as described above, if the lamp bulb of the headlamp is disconnected, when the combination lamp is installed and removed, there will be a gap between the headlamp and the rear wall of the lamp housing. Since there is a work space, you can easily insert your hand into the space and replace the valve.
