The lower end of the windshield is inserted into the V-shaped opening; the raised portion and the bottom of the opening are both against the outer surface of the instrument sheet metal.

An anti-collision sponge is arranged between the front glass and the front instrument cover.

The beneficial effects of the present invention are:

In this technical solution, the windshield sealing strip is set between the ventilation cover, the front windshield and the instrument sheet metal, and the structure of the ventilation cover and the front windshield sealing strip makes the assembly between the front windshield and the ventilation cover It is convenient and through the use of the anti-collision pad between the front windshield and the front windshield sealing strip, the protection assembly efficiency is improved, and the airflow in the cabin can be prevented from entering the cab, and the front windshield is also protected. Impact protection.

Detailed ways

The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.

As shown in Figure 1, the engine cabin outer panel 1 is connected with an end of the engine cabin sound insulation panel 13, the engine cabin outer panel 1 is overlapped with the ventilation cover plate 12, and one end of the lower bottom edge of the running water tank 11 is connected to the bottom of the ventilation cover panel 12. The bottom surface is lapped, and the other end of the lower bottom edge of the water tank 11 is connected with the front wall sheet metal 10, the front wall reinforcement sheet metal 8 and the dash panel inner sheet metal 9, and the dash panel inner sheet metal 9 and the cowl reinforcement sheet metal 8 are all connected to the instrument sheet metal 7, the instrument sheet metal 7 is overlapped with the front windshield 2 and the ventilation cover 12 through the front windshield sealing strip 14, and a front connecting glass is arranged between the instrument sheet metal 7 and the front windshield 2 Glue 3, the front windshield 2 and the front instrument cover 6 are overlapped by the anti-collision sponge 4, and a wiper 5 is arranged on the outside of the front windshield 2.

In this application, the surface of the front windshield that is in contact with the wiper is the outer surface, and the surface opposite to the cab is the inner surface. In other parts of the application, such as the ventilation cover, the surface opposite to the cabin is the inner surface. Surface, the surface opposite to the inner surface is the outer surface, as for the inner and outer surfaces of the windshield sealing strip, the inner and outer surfaces are determined according to the direction of the front windshield.

As shown in Figure 2, the front windshield weather strip 14 includes a weather strip body 141, the lower end of the weather strip body 141 is provided with an arc-shaped bend to form an opening 142; The bent portion 143 , the bent portion reduces the opening of the opening, and prevents the inserting portion 121 from being removed from the opening 142 when the inserting portion 121 of the ventilation cover is inserted into the opening 142 .

On the outer surface of the joint between the opening 142 and the weather strip body 141, an extension 144 extending obliquely upward is provided, and a V-shaped opening is formed between the extension portion 144 and the weather strip body 141; the lower end of the windshield 2 is inserted into the V-shaped opening inwards; in this way, the extension serves to seal the gap between the vent flap and the windshield.

A raised portion 145 is provided on the inner surface of the weather strip body 1 . Bottoms of the raised portion 145 and the opening 142 are both against the outer surface of the instrument panel 7 . Through the bottom of the raised portion 145 and the opening 142, the double-layer seal between the windshield 2 and the instrument sheet metal 7 is realized, which ensures the sealing effect.

A first reinforcing rib 146 is disposed in the sealing strip body 141 and the opening, and a second reinforcing rib 147 is disposed in the extension portion, and the first reinforcing rib and the second reinforcing rib are not connected.

The first reinforcing rib of this application is spoon-shaped. In this application, the material of the front windshield sealing strip is rubber, which can ensure the elasticity of the front windshield sealing strip and play the role of shock absorption and sound insulation between two adjacent parts. , and can guarantee a certain strength and play a fixed role.

The ventilation cover 12 includes a ventilation cover body and an inserting portion 121 arranged on the lower surface of the ventilation cover body; it realizes the connection between the ventilation cover body and the windshield sealing strip and plays a sealing role.

The inserting part 121 is a diamond-shaped structure. During installation, the inserting part is directly inserted into the opening by pressing, reducing the structure of fixed connection, easy to operate, and good in sealing performance.

An anti-collision rubber pad 15 is provided between the weather strip body 141 and the front windshield.
