Description
Technical field
the present invention relates to motor car engine, especially relate to a kind of decorative cover of engine and install and linkage structure.
Background technique
decorative cover of engine is assemblied in motor car engine one part for decorating, and purposes has two: 1, block the part such as wire harness and pipeline in engine compartment, to strengthen aesthetic appearance; 2, effect that is heat insulation, sound insulation is played, to improve the NVH(noise of vehicle, vibration and sound vibration roughness) performance.Existing decorative cover of engine is mostly integrated through injection molding part, to be threaded connection or non-dismountable connection and motor or its support installing are fixed, installation and the unloading process more complicated of decorative cover of engine will be caused like this, even also need to utilize spanner or screw-driver, for the motor needing often maintenance, to a certain extent, add labor intensity beyond doubt, bring inconvenience.
in addition, due to the frequent dismounting of the vibration in vehicle using process and decorative cover of engine, need to provide effective twelve Earthly Branches to support to decorative cover of engine, ensure its enough installation strength.Otherwise in vehicle travels, decorative cover of engine there will be the problem loosened with abnormal sound, even easily causes distortion and subsides.
Summary of the invention
the decorative cover of engine that the object of the present invention is to provide a kind of dismounting simple and convenient, fixed is installed and linkage structure, it can solve loosening and sending the problem of abnormal sound of the decorative cover of engine produced because of vibration in vehicle travel process effectively, the problem of decorative cover of engine dismounting inconvenience when simultaneously can also solve engine maintenance, maintenance.
the object of the present invention is achieved like this:
a kind of decorative cover of engine is installed and linkage structure, comprise decorative cover of engine and cylinder cover of engine, feature is: in the cover chamber of decorative cover of engine reverse side, corner is provided with four as the decorative cover supporting post connected, sidewall and downwards equal opening is on one side provided with in decorative cover supporting post, the supporting post chamber of inverted cone, an accent stiffening rib is provided with at the accent in supporting post chamber, more than one lower stiffening rib is provided with at the inner wall lower in supporting post chamber, accent draw-in groove is formed between accent stiffening rib and lower stiffening rib, rubber sleeve to be installed in accent draw-in groove from the sidewall opening of decorative cover supporting post and to be stuck in accent draw-in groove, the rubber sleeve through hole of up/down perforation is provided with at the center of rubber sleeve, cylinder cover of engine is provided with the installation base of integrally casting, installation base is provided with the installation base cavity of upward opening, connecting rod bulge loop is provided with at lower end, the middle part sidewall of connecting rod, the bottom of the connecting rod bulge loop of connecting rod is inverted cone lower beam, the top of the connecting rod bulge loop of connecting rod is to extend in the rubber sleeve through hole of rubber sleeve, the upper boom that sidewall is smooth, the flat head of upper and lower chamfering is provided with on the top of the upper boom of connecting rod, the inverted cone lower beam of connecting rod is connected in the installation base cavity of installation base by sulfuration, the upper boom of connecting rod runs through the rubber sleeve through hole of rubber sleeve by interference fit, and be tightly fixedly connected with rubber sleeve, flat-nosed external diameter is slightly larger than the external diameter of the rubber sleeve through hole of rubber sleeve.
in rubber sleeve sidewall be provided with more than one annular rubber sleeve draw-in groove (a rubber sleeve draw-in groove and accent stiffening rib supporting, plural rubber sleeve draw-in groove and accent stiffening rib and more than one lower stiffening rib all supporting), the accent stiffening rib of decorative cover supporting post is installed in the rubber sleeve draw-in groove of rubber sleeve.
four rubber sleeve positive stop lug boss are provided with on the top of " U " shape accent stiffening rib of decorative cover supporting post.
the horizontal cross sectional geometry of supporting post chamber, accent stiffening rib, lower stiffening rib, accent draw-in groove is " U " shape.
" U " shape opening in the supporting post chamber of two the decorative cover supporting posts in left and right is oppositely arranged.
decorative cover supporting post of the present invention is connected by interference fit with the copper connecting rod on the installation base of cylinder cover of engine by rubber sleeve, so both be beneficial to dismounting and the installation of decorative cover of engine and cylinder cover of engine, again by having installed the rubber sleeve with elastic buffer effect additional, thus can effectively solve because of in vehicle traveling, loosening and abnormal sound problem of the decorative cover of engine that engine luggine causes, and mounted engine adorns distortion and the collapse phenomenon of cover.Meanwhile, connecting rod made of copper also can avoid the frictional loss that produces because of frequent relative movement between connecting rod and rubber sleeve.In addition, rubber sleeve is installed into accent draw-in groove from the side of decorative cover supporting post, and be not related with other parts in disassembly process like this, this mounting connection structure can ensure the working life of decorative cover of engine.
because decorative cover of engine and decorative cover supporting post are integral type, the production and processing of such decorative cover of engine is just very simple, and cost is also low, and enhance the intensity of engine decorative cover body, ensure that and installs fixing reliability.
sidewall and downwards all opening, supporting post chamber in inverted cone is provided with in decorative cover supporting post, an annular accent stiffening rib is provided with at the accent in supporting post chamber, be provided with the lower stiffening rib of more than one annular at the inner wall lower in supporting post chamber, such structure function is: 1, can play reinforing function; 2, accent stiffening rib and lower stiffening rib can form accent draw-in groove, are convenient to rubber sleeve and install or remove from the side; Meanwhile, decorative cover supporting post also can be installed in the rubber sleeve draw-in groove in the middle part of rubber sleeve, forms mutual card structure, and serves double buffering damping effect.
described connecting rod is copper material, and copper material can reduce the frictional loss produced because of relative movement.The upper boom of connecting rod runs through the rubber sleeve through hole of rubber sleeve by interference fit, and be tightly fixedly connected with rubber sleeve, flat-nosed external diameter is slightly larger than the external diameter of the rubber sleeve through hole of rubber sleeve, such structure function is: 1, can prevent automobile connecting rod in Zhi Yunhang from exiting because of vibration from the rubber sleeve through hole of rubber sleeve, decorative cover of engine is separated with cylinder cover of engine; 2, be convenient to installation and removal, and the effect of bumper and absorbing shock can be played.
therefore, project organization of the present invention is simple, and be easy to realize, its beneficial effect is: the noise significantly reducing motor, serves heat insulation, cushioning effect, and easy accessibility, quick, need not any assistant tool, is convenient to the maintenance, repair of motor.
