Problems solved by technology

However, in the support structure, when the cover member is assembled above the engine and the intake manifold, the bending force acting on the rod-shaped member may excessively act on the protrusion due to force. on, which may cause the raised part to crack (crack)

[0029] 1 to 8 are drawings illustrating a first embodiment of the present invention. 1 is an exploded perspective view showing an engine 10 and an intake manifold 20 including a support structure of a cover member 30 , and the cover member in a state detached from the engine 10 and intake manifold 20 . In addition, in this figure, the outlines of the cylinder block 2 of the engine 10 and various auxiliary mechanisms provided around it are shown by phantom lines (dashed lines). In addition, in FIG. 1 , the right side of the drawing corresponds to the rear side of the engine 10 , and the left side of the drawing corresponds to the front side of the engine 10 .

[0030] The engine 10 has an engine main body 4 composed of a cylinder block 2 and a cylinder head 3 provided above the cylinder block 2 . In addition, the engine 10 is an inline 4-cylinder engine provided with four cylinders along the longitudinal direction D1 of the engine main body 4 . The engine 10 is provided such ...

[0057] In the above-mentioned first embodiment, the structure in which the second support mechanism portion 50 provided on the side of the intake manifold 20 is integrally formed with the upper surface of the middle divided molded body 20B has been described, but the present invention is not limited thereto. The second support mechanism part is formed integrally with the upper surface of the outer divided molded body 20A, and the same effect as the support structure of the lid member 30 in the first embodiment can be obtained. 9 and 10 are a front view and a side view, respectively, of a second support mechanism part 70 in an example (second embodiment) in which the second support mechanism part is formed integrally with the upper surface of the outer divided molded body 20A. Hereinafter, the same reference numerals are assigned to the same configurations as those of the above-mentioned first embodiment, and description thereof will be omitted.

Abstract

A supporting framework of the cap body part (30) of the invention includes a base (51) formed together with the suction manifold on the upper surface of the suction manifold (20), an axle-shaped part (52) extending along the direction orthogonal to the cylinder orientation of the engine (10) seeing from the downward direction, a flexible part (56) mounted on the axle-shaped part which is inserted inside of the flexible part, a supporting part (53) for limiting downwards displacement of the axle-shaped part and the flexible part, in which a clamping part (62) for clamping the flexible part is provided on the cap body part. The invention can not only ensure easy assembling performance of the cap body part, but also improve the supporting intensity relative to the cap body part.

Description

technical field [0001] The present invention relates to a support structure of a cover member covering an engine and an intake manifold provided on either side of the engine. Background technique [0002] As we all know, the upper part of the engine mounted in the engine room of the vehicle and its surroundings are intricately provided with components such as harnesses and hoses. Therefore, the engine seen after opening the bonnet The visual state of the interior is not necessarily ideal. In addition, various radiated sound waves emitted from the engine can also enter the vehicle interior through the dash panel. In recent years, in order to improve the above-mentioned problems, the structure of providing a cover member covering the top of the engine has become more and more widely used. [0003] In order to further expand the effect of improving the visual state of the engine compartment and suppressing the radiated sound waves from entering ...
