Abstract
A front wall structure of a cab of a commercial vehicle comprises an upper cross beam (1), a lower cross beam (2) and a front wall baffle (3), wherein the upper cross beam (1) is welded with the upper part of the front wall baffle (3), and the upper part of the lower cross beam (2) is welded with the lower part of the front wall baffle (3); the upper cross beam (1) is of an L-shaped opening structure (4); the lower cross beam (3) is of a groove-shaped structure, and the lower cross beam (2) and the front wall baffle (3) are welded to form a closed beam cavity (5). The weight is light and the cost is low; the area of the functional part mounting hole is large, and the functional configuration of the cab is increased.
Description
Technical Field
The utility model relates to a enclose before the driver's cabin, more specifically the structure is enclosed before commercial car driver's cabin that says so belongs to car body structure technical field.
Background
At present, the front wall of an automobile cab is generally in a plate type structure, and the front wall is formed by punching and molding inner and outer thick plates and then is welded and combined together. However, the plate-type structure is heavy and is not in line with the current trend of light weight; and two large-scale plate materials are punched, pressed and welded to form a beam cavity, so that the beam cavity is difficult to form, the requirement on punching equipment is high, and the manufacturing cost is high.
Disclosure of Invention
The utility model aims to provide a enclose structure before commercial car driver's cabin to the weight that the apron structure exists before current auttombilism room heavier, the difficult scheduling problem of shaping.
In order to achieve the above object, the technical solution of the present invention is: the utility model provides a structure is enclosed before commercial car driver's cabin, includes entablature, bottom end rail and before enclose the baffle, entablature with before enclose baffle upper portion and weld mutually, bottom end rail upper portion with before enclose baffle lower part and weld mutually.
The upper cross beam is of an L-shaped opening structure.
The lower cross beam is of a groove-shaped structure, and a closed beam cavity is formed after the lower cross beam and the front wall baffle are welded.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model is formed by sequentially welding the upper beam, the front wall baffle and the lower beam, and has light weight and low cost; the area of the functional part mounting hole is large, and the functional configuration of the cab is increased.
2. The utility model discloses play the energy-absorbing effect when middle and upper cross beam collides, transmit the impact force when the bottom end rail collides, protect the passenger, provide safe living space.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an exploded view of the present invention.
Fig. 3 is a side view of the present invention.
Fig. 4 is a sectional view a-a in fig. 3.
In the figure, an upper cross beam 1, a lower cross beam 2, a front wall baffle 3, an L-shaped opening structure 4 and a closed beam cavity 5.
Detailed Description
The invention is described in further detail below with reference to the following description of the drawings and the detailed description.
Referring to fig. 1 to 2, a front wall structure of a cab of a commercial vehicle comprises an upper cross beam 1, a lower cross beam 2 and a front wall baffle 3; the upper cross beam 1 is welded with the upper part of the front wall baffle 3, and the upper part of the lower cross beam 2 is welded with the lower part of the front wall baffle 3.
Referring to fig. 3 to 4, further, the upper cross beam 1 is an L-shaped opening structure 4. The structure plays a role in energy absorption during collision, protects passengers and provides a safe living space.
Referring to fig. 3 to 4, further, the lower cross beam 2 is of a groove-shaped structure, and the lower cross beam 2 and the dash panel 3 are welded to form a closed beam cavity 5. The structure transmits force to the floor rail at the time of collision, thereby reducing the frontal impact force.
Referring to fig. 1 to 4, when the technical solution of the present invention is applied to a D320 cab, the weight of the front wall structure is usually 26kg, which is lighter than other racing cars and has lower cost.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, above-mentioned structure should all be regarded as belonging to the utility model discloses a protection scope.
Claims (3)
1. The utility model provides a enclose structure before commercial car driver's cabin which characterized in that: the front wall baffle plate is characterized by comprising an upper cross beam (1), a lower cross beam (2) and a front wall baffle plate (3), wherein the upper cross beam (1) is welded with the upper part of the front wall baffle plate (3), and the upper part of the lower cross beam (2) is welded with the lower part of the front wall baffle plate (3).
2. A commercial vehicle cab front wall structure according to claim 1, characterized in that: the upper cross beam (1) is of an L-shaped opening structure (4).
