Among this preceding defrosting structure, preceding defrosting grid direct design for with instrument board reinforcing plate integral type structure, compare in current individual joint structure, reduced spare part quantity and reduced the mould and examined a development, the cost is reduced, simple structure moreover has also reduced weight to a certain extent. Simultaneously cooperate the protruding muscle structure of welding on the instrument board reinforcing plate, paste through the protruding muscle of welding between instrument board reinforcing plate and the instrument board body and lean on and realize vibration friction welding, preceding defrosting grid and instrument board fit clearance have been eliminated, the poor not good problem of face, the intensity of installation has been promoted, adopt to accomplish vibration friction welding between the form of the protruding muscle of welding and the instrument board body moreover, for plane welding, there can not be the welding clearance after the welding, the welded firmness is higher, welded operation is more simple and convenient simultaneously.
In the front defrosting structure of the automobile, the instrument panel reinforcing plate is provided with a plurality of groups of the welding convex ribs, the plurality of groups of the welding convex ribs are distributed at intervals along the width direction of the instrument panel reinforcing plate, and the plurality of welding convex ribs in each group are distributed at intervals along the length direction of the instrument panel reinforcing plate. Through set up array's welding protruding muscle on the instrument board reinforcing plate for preceding defrosting grid and instrument board reinforcing plate's an organic whole piece can be fine and realize vibration friction welding between the instrument board body, and can not have weld gap after the welding, the welding strength of each department is all better and even, and welded firmness is higher, and welded operation is more simple and convenient simultaneously, has guaranteed the intensity of installation.
In the front defrosting structure of the automobile, the welding convex ribs are all in a long strip shape. The welding convex rib is in a long strip shape, so that a larger welding area is provided, the welding firmness is higher, and the installation strength is ensured.
In the front defrosting structure of the automobile, the welding convex rib is trapezoidal in section along the vertical direction, and the lower bottom edge of the trapezoid is connected with the instrument panel reinforcing plate. Through the arrangement, the operation of vibration friction welding is simpler and more convenient.
In the front defrosting structure of the automobile, the instrument panel body comprises an instrument panel framework and an instrument panel skin which is fixedly covered on the instrument panel framework, and the welding convex ribs on the instrument panel reinforcing plate are fixed with the instrument panel framework through vibration friction welding. During the installation, earlier with before the integral type defrost grid with the instrument board reinforcing plate through vibration friction welding on instrument board skeleton, again with before defrost tuber pipe and instrument board skeleton through the self-tapping screw fastening loading together, be connected to together with the air conditioner and realize with windshield defrosting, defogging function before the car, simple to operate has promoted intensity, has eliminated the clearance face of assembly poor.
In the above front defrosting structure of an automobile, the front defrosting grille and the instrument panel reinforcing plate are integrally formed by injection molding. Simple structure, the preparation is convenient, and is with low costs, has eliminated the assembly clearance face difference that produces because of the joint moreover, and integrated into one piece intensity is also higher moreover.
Compared with the prior art, this preceding defrosting structure of car has following advantage: preceding defrosting grid direct design for with instrument board reinforcing plate integral type structure, and through vibration friction welding between welding protruding muscle and the instrument board body, compare in current individual joint structure, spare part quantity has been reduced, and mould and examine a development have been reduced, the cost is reduced, preceding defrosting grid and instrument board fit clearance have been eliminated, the poor not good problem of face, the intensity of installation has been promoted, and simple structure, weight has also been reduced to a certain extent, there is not welding gap after the welding, the welded firmness is higher, welded operation is more simple and convenient simultaneously.
