Description

[Detailed description of the invention] This invention relates to the cab structure of a freight vehicle, and its purpose is to
The instrument panel connection structure has been improved to improve the strength of both ends of the lower part of the front window.

Conventionally, the coupling structure between an instrument panel and a front pillar is as shown in FIG.

That is, a gusset 4 having a single mounting surface is fixed by welding to a vertical wall surface on the side of the vehicle at the inner corner of the front pillar 2 between the front panel 1 and the outer pillar 2as the inner pillar 2b, and the instrument is attached to the vertical wall surface on the side of the vehicle. At the same time as fixing the lower panel 5b, a reinforcement 3 is fixed to the inner upper edge of the front panel 1, and an instrument upper panel 5a is fixed to this to form an instrument panel 5 combined with the instrument lower panel 5b. was.

In some cases, the instrument upper panel 5a was directly fixed to the inner upper edge of the front panel 1 without fixing the reinforcement 3.

In the former case, in order to reliably weld the instrument upper panel 5a and the reinforcement 3 to the front pillar 2 side, spot welding is not possible due to the cab structure and assembly order, and gas welding, which has poor workability, has to be performed. There wasn't.

Also, in the former and latter cases, the panel corresponding to the instrument lower panel 5b is displaced rearward from the front pillar 2 at both ends.

Therefore, in this case, the gusset 4 must be welded to the front pillar 2 side and the instrument lower panel 5b must be joined, which has a negative effect on work efficiency and reduces the strength of the joints on both sides of the instrument panel 2. There were also some difficulties.

The present invention solves the above-mentioned problems of the conventional structure.

Its feature is that it has a gusseted shape, and the instrument upper panel can be attached entirely by spot welding, which improves workability and improves strength.

Embodiments of the present invention will be described below with reference to FIGS. 2 and 3.

1 is a front panel, and 2 is a front pillar, which is composed of an outer pillar 2as and an inner pillar 2b, and a bent part 2c perpendicular to the inner pillar 2b is formed at the joint with both ends of the front panel 1. The bent portion 2c and the front panel 1 are joined together by spot welding.

Therefore, the bent portion 2C forms a surface in the same direction as the surface of the front panel 1, and the bent portion 2C and the inner pillar 2b
and form a right-angled corner.

Two right-angled fixing surfaces 5a formed in an L shape corresponding to the right-angled corner between the bent portion 2c and the inner pillar 2b.
, 5b are spot welded.

That is, one fixed surface 6a is fixed to the surface of the bent portion 2c, which is a vertical wall surface at the front of the vehicle, and the other fixed surface 6b is fixed to the surface of the inner pillar 2b, which is a vertical wall surface at the side of the vehicle.

The instrument upper panel 5a of the instrument panel 5 is spot welded to the inner upper edge of the front panel 1 and the upper edge formed by bending the gusset 6 at right angles around the fixing surface 6a+6b of the right angle surface. Further, the instrument lower panel 5b is fastened and fixed to the bent end surface of the fixing surface 6b of the gusset 6 at a position displaced rearward from the front pillar 2, and is coupled to the instrument upper panel 5a.

Since the present invention has the above-mentioned structure, the instrument upper panel can be installed by spot welding the inner upper edge of the front panel and the upper edge bent around the L-shaped gusset. This eliminates the need for gas welding, which is difficult to work with, and improves the efficiency of installation work.In addition, since the instrument panel and front pillar are connected via an L-shaped gusset, there is no corner The strength of the corner portions is increased, and the deformation and movement of the instrument panel toward the rear of the vehicle in the event of a frontal or front end collision is reduced, resulting in the advantage of securing a survival space.

Claims (1)

[Scope of utility model registration request] At the internal corner of the front pillar and front panel of the cab, there is an L-shaped fixing surface with two right-angled sides to connect the instrument ronnel, and around this fixing surface there is a peripheral edge bent at right angles to the fixing surface. The instrument upper panel is spot welded to the front panel and the upper edge of the gusset, and the instrument lower panel is attached to the edge of the gusset at a position displaced rearward from the front pillar. Cab structure characterized by tightening and fixing to the edge.
