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.
Description
technical field [0001] The invention relates to automobile engine technology, in particular to a connection structure between an engine decorative cover and an engine cylinder head. Background technique [0002] In the assembly of the engine trim cover, the engine trim cover is usually fixed on the mounting boss of the engine cylinder head with ordinary bolts. The biggest disadvantage of this installation method is that it is difficult to disassemble and assemble. Since it is connected by bolts, a wrench or a screwdriver must be used for disassembly and assembly, and the engine decorative cover is a part that often needs to be disassembled, so this installation structure will give users Bring a lot of inconvenience. Moreover, there is a rigid connection between the engine decorative cover and the engine cylinder head. If the connecting bolts are not tightened, or the wires are slipped due to repeated disassembly and assembly, the vibration of the engine will make the engine...
