Detailed Description
In order to make the technical solutions of the present invention clearer and clearer for those skilled in the art, the present invention will be described in further detail with reference to the following embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.
As shown in fig. 1-4, the thin wall of moulding plastics of a MQB instrument front shroud that this embodiment provided includes instrument front shroud support 1, foam-rubber cushion 8 and filtration screen panel 9, is provided with foam-rubber cushion 8 on the inside both sides wall of instrument front shroud support 1, is provided with cavity 11 in the instrument front shroud support 1 inner wall, and foam-rubber cushion 8 is provided with connecting pipe 10 in cavity 11 one side, and connecting pipe 10 runs through instrument front shroud support 1 one side and is connected with filtration screen panel 9.
The connecting pipe 10 is connected with the inside of the instrument front cover support 1 in a clamping mode through a clamping groove, the inside of the connecting pipe 10 is communicated with the cavity 11 through a hollow structure, and the sponge cushion 8 is connected with the connecting pipe 10 and the inner wall assembly of the instrument front cover support 1 through a sealant 7.
