The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 and 2, a wind deflector assembly in the prior art includes a rigid mounting member 1 and an elastic wind deflector 2, the mounting member 1 includes two metal frameworks which are long and distributed along the length direction of the mounting member, the wind deflector 2 is a rubber wind deflector, the mounting member 1 is arranged on the upper side of the wind deflector 2, and the mounting member 1 and the wind deflector 2 are fixedly connected through a plurality of push nails 4.

Because in the above-mentioned deep bead assembly, need use a plurality of ejector pins 4 to be connected installed part 1 and deep bead 2, the quantity of spare part has been increased, thereby make manufacturing procedure comparatively complicated, and manufacturing cost has been increased, in addition, because installed part 1 and ejector pin 4 are made by metal material, and during the deep bead assembly used, mostly expose outside, consequently receive external environment's influence easily (including the sunshine, the wind blows, rain), it is ageing to lead to installed part 1 and ejector pin 4 to take place the corrosion easily, make appear becoming flexible between installed part 1 and the deep bead 2, influence the use of deep bead assembly, and its life has been shortened.

Based on the above factors, the present invention provides four embodiments, as follows:

example 1

As shown in fig. 3 and 4, the hybrid molded windshield assembly of the heavy truck according to embodiment 1 includes a rigid mounting member 1 and an elastic windshield 2, the mounting member 1 is an EPDM composite sheet, the windshield 2 is a rubber windshield, the mounting member 1 and the windshield 2 are both long and parallel in the length direction, and the mounting member 1 is disposed above the windshield 2 and is mold-pressed and connected with the windshield 2.

In this embodiment, adopt the mould pressing to be connected between installed part 1 and the deep bead 2, consequently need not to carry out fixed connection through pushing away the nail, practiced thrift manufacturing cost and mould pressing connection convenient operation, simplified production processes. Installation component 1 is the EPDM composite sheet, compares in traditional sheet metal, has avoided the possibility of taking place the corrosion, has alleviateed weight, and has further reduced manufacturing cost. The wind shield 2 is arranged below the mounting part 1 and is made of rubber, and the wind shield has elasticity, so that the shock absorption and the buffering of a heavy truck are facilitated.

It should be noted that, for convenience of molding production, the material for producing the mounting member 1 is not limited to the EPDM (ethylene propylene diene monomer) material disclosed in this embodiment, and other high temperature resistant (specifically, 120 ℃ or higher) elastic materials can be used for producing the wind deflector assembly, so as to achieve the purposes of reducing weight and preventing rust. In addition, other materials with elasticity can be selected for the wind deflector 2, and the function of shock absorption and buffering is achieved.

The upside of deep bead 2 is provided with two rows of mould pressing holes 3, and two rows of mould pressing holes 3 set up side by side along the direction of height of deep bead 2, and mould pressing hole 3 on every row of mould pressing hole 3 is along the length direction interval distribution of deep bead 2, and mould pressing hole 3 is the mould pressing through-hole.

After adopting above-mentioned design, in carrying out the mould pressing production process, the production material of installed part 1 can flow into to mould pressing hole 3 in to increase the area of contact of installed part 1 and deep bead 2, make in the deep bead assembly after the shaping, deep bead 2 is strengthened with the joint strength of installed part 1. The mould pressing hole 3 is provided with two rows, and the mould pressing hole 3 of every row is provided with a plurality ofly to increased the quantity in mould pressing hole 3, further strengthened being connected between deep bead 2 and installed part 1, guaranteed this deep bead assembly's structural strength.

The wind shield 2 is arranged between two side surfaces of the mounting part 1 and has the same distance with the two side surfaces of the mounting part 1; the thickness of the wind deflector 2 is 2 mm.
