Abstract
The invention relates to a connection structure of an engine decorative cover and an engine cylinder cover. The connection structure comprises an installation seat fixed on the engine decorative cover and a ball stud fixed on an installation boss of the engine cylinder cover. A cavity with a side opening is arranged on the lower end of the installation seat. An installation hole communicated with the cavity is arranged in the lower end face of the installation seat. An elastic connection sleeve is assembled in the cavity, and the lower end of the elastic connection sleeve cooperates with the installation hole. A protruding part used for preventing the connection sleeve from falling out of the installation hole is arranged on the connection sleeve. A clamp groove which is provided with a downward opening and used for storing a head part of the bulb stud is arranged in the connection sleeve. The connection structure is simple and convenient to disassemble. Problems of noise generated by an engine decorative cover and of resonance generated by the engine decorative cover and an engine in the prior art are effectively solved. Abnormal sound of an engine compartment caused by looseness of the engine decorative cover is effectively avoided. The connection sleeve can be disassembled and assembled via the side opening in the cavity conveniently and quickly without damage to the installation seat during the assembling and disassembling processes.

The linkage structure of a kind of decorative cover of engine of the present invention and engine cylinder cover, comprise the fitting seat be fixed on decorative cover of engine, the mode that is threaded connection is fixed on ball stud on the installation base of engine cylinder cover, the lower end of described fitting seat is provided with the cavity of lateral opening, and the lower end surface of described fitting seat is provided with the mounting hole with described cavity connects; The connecting sleeve with its upper side wall Elastic Contact is equipped with in described cavity, described connecting sleeve has elasticity and its lower end coordinates with described mounting hole, described connecting sleeve is provided with the protuberance for preventing connecting sleeve from deviating from from described mounting hole, and described connecting sleeve is provided with that Open Side Down, for holding the draw-in groove of the ball head on described ball stud.
Adopt technique scheme, the connection between decorative cover of engine and engine cylinder cover is realized by ball stud, so both be convenient to decorative cover of engine cover from engine cylinder and take apart, again by the elastic buffer of connecting sleeve, avoid being rigidly connected between decorative cover of engine and engine cylinder cover, effectively solve the problem that the noise problem of decorative cover of engine in prior art and decorative cover of engine and motor easily produce resonance.Connecting sleeve carries out dismounting by the lateral opening on cavity simultaneously, and convenient and swift, can not damage fitting seat in cargo handling process, because connecting sleeve is easily damaged parts, the fitting seat of this structure extends the working life of fitting seat and decorative cover of engine.
Further, be provided with toroidal cavity in described connecting sleeve, described toroidal cavity is between the outer side wall and described draw-in groove of connecting sleeve, and toroidal cavity enhances the buffering and damping effect of connecting sleeve.
Further, described fitting seat comprises the side plate that cross section is ∩ shape, and the upper end of described side plate is fixed on described decorative cover of engine, and the lower end of described side plate is provided with two pieces of flat boards to surround described cavity; Be provided with the gusset of reinforing function in two pieces of flat boards between one flat plate by the top and described decorative cover of engine, described mounting hole to be located in two pieces of flat boards on one flat plate on the lower.Fitting seat structure is simple, and cost of production is low, and gusset ensure that the reliability of fitting seat, erection & lift seat vertical applied force ability.
Further, described fitting seat and described decorative cover of engine one-body molded, make fitting seat fixing more firm.
Structure of the present invention is simple, be convenient to dismounting, again by the elastic buffer of connecting sleeve, effectively solve the problem that the noise problem of decorative cover of engine in prior art and decorative cover of engine and motor easily produce resonance, effectively prevent decorative cover of engine and loosen produced engine compartment abnormal sound; Connecting sleeve carries out dismounting by the lateral opening on cavity simultaneously, convenient and swift, can not damage fitting seat, extend the working life of fitting seat and decorative cover of engine in disassembly process.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
A kind of decorative cover of engine as shown in Figure 1 and the linkage structure of engine cylinder cover, comprise the fitting seat 2 be fixed on decorative cover of engine 1, the mode that is threaded connection be fixed on ball stud 3 on the installation base 4 of engine cylinder cover.Fitting seat 2 is one-body molded with decorative cover of engine 1, and the lower end of fitting seat 2 is provided with the cavity 7 of lateral opening, and the lower end surface of fitting seat 2 is provided with the mounting hole 8 be communicated with cavity 7.The connecting sleeve 5 with its upper side wall Elastic Contact is equipped with in cavity 7, connecting sleeve 5 has elasticity and its lower end coordinates with mounting hole 8, connecting sleeve 5 is provided with the protuberance 10 for preventing connecting sleeve 5 from deviating from from mounting hole 8, and connecting sleeve 5 is provided with that Open Side Down, for holding the draw-in groove 9 of the ball head 6 on ball stud 3.
As shown in Figure 3, be provided with toroidal cavity 15 in connecting sleeve 5, toroidal cavity 15 is between the outer side wall and draw-in groove 9 of connecting sleeve 5.
As shown in Figure 2, fitting seat 2 comprises the side plate 12 that cross section is ∩ shape, and the upper end of side plate 12 is fixed on decorative cover of engine 1, and the lower end of side plate 12 is provided with two pieces of flat boards 11 to surround cavity 7.The gusset 13 of reinforing function has been provided with between one flat plate by the top and decorative cover of engine 1 in two pieces of flat boards 11; Mounting hole 8 to be located in two pieces of flat boards 11 on one flat plate on the lower.The outer of side plate 12 is arranged with the stiffening rib 14 be in tilted layout.
As shown in Figure 2 and Figure 4, decorative cover of engine 1 is provided with 4 fitting seats 2, decorative cover of engine 1 is arranged on engine cylinder by linkage structure of the present invention and covers, the mode that now ball stud 3 is threaded connection is fixed on the installation base 4 of engine cylinder cover, ball head 6 on ball stud 3 coordinates with draw-in groove 9, and connecting sleeve 5 can bumper and absorbing shock.During dismounting decorative cover of engine 1, because ball head 6 and connecting sleeve 5 amount of interference are little, so the withdrawal force that ball head 6 departs from even needed for draw-in groove 9 is smaller, and the protuberance 10 on connecting sleeve 5 can effectively prevent connecting sleeve 5 from deviating from from mounting hole 8, in the unloading process of decorative cover of engine 1, connecting sleeve 5 can not skid off from mounting hole 8.Connecting sleeve 5 is arranged in cavity 7, from the lateral opening of cavity 7, connecting sleeve 5 can be taken apart when connecting sleeve 5 damages, unloading process can not damage fitting seat 2, and because connecting sleeve 5 is easily damaged parts, the fitting seat 2 of this structure substantially prolongs the working life of fitting seat 2 and decorative cover of engine 1.Upper and lower in the present invention is as the criterion with accompanying drawing 1.
