Problems solved by technology

[0003] The main disadvantages of the traditional upper side beam structure are: 1. Water accumulation in the upper area is easy to cause rust, so the parts in this area use galvanized sheets or add covering rubber strips to solve the rust problem, and the cost is high; 2. Solve it by laser welding There is a problem of rusting on the cutting edge, but laser welding requires high manufacturing precision, and the cost of laser welding is high

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Figure 1 to Figure 3 The reference numerals in the figure are: upper side beam 1; front wheel house 2; engine hood hinge lower support 3; front wheel house upper reinforcing plate 4; sealing coating glue 5.

[0020] Such as Figure 1 to Figure 3 As shown, a front cabin upper side sill structure includes an upper side sill 1, a front wheel house 2, a bonnet hinge lower bracket 3 and a front wheel house upper reinforcement plate 4, and the upper side sill 1 and the hood hinge lower bracket 3 Enclosed to form a hollow cavity, the upper end of the reinforcement plate 4 on the front wheel house is overlapped with the upper end of the lower bracket 3 of the hood hinge, and the lower end of the reinforcement plate 4 on the front wheel house is connected to the front wheel. One end of the cover 2 is overlapped, the other end of the front whee...

Abstract

The invention provides a nose cabin roof side rail structure which comprises a roof side rail, a front wheel cover, an engine cover hinge lower support and a front wheel cover upper reinforcing plate. The roof side rail and the engine cover hinge lower support enclose a hollow cavity. The upper end of the front wheel cover upper reinforcing plate is in lap joint with the upper end of the engine cover hinge lower support. The upper end of the front wheel cover upper reinforcing plate, the upper end of the engine cover hinge lower support and the upper end of the roof side rail are stacked. The upper end of the engine cover hinge lower support is disposed between the upper end of the front wheel cover upper reinforcing plate and the upper end of the roof side rail. The upper end of the engine cover hinge lower support is lower than the upper end of the front wheel cover upper reinforcing plate and the upper end of the roof side rail, so that a gluing groove which is high on two sides and low in the middle and is filled with sealing coating glue is formed. The nose cabin roof side rail structure has the advantage that rust prevention can be achieved under the premise that cost is not increased.

Description

technical field [0001] The invention relates to a car body, in particular to a front cabin upper side beam structure in the car body. Background technique [0002] The upper side rail of the front compartment of the engine compartment of the vehicle body is one of the important areas that affect the passive safety of the vehicle body, and it is also an important installation hard point of the front suspension shock absorber. The quality of its structure directly affects the collision safety and the durability of the front suspension installation point. [0003] The main disadvantages of the traditional upper side beam structure are: 1. It is easy to accumulate water in the upper end area and cause rust, so the parts in this area use galvanized sheets or add covering rubber strips to solve the rust problem, and the cost is high; 2. Solve it by laser welding There is a problem of rusting on the cutting edge, but laser welding requires high manufacturing precision, and the cost...
