Description

  The present invention relates to an engine cover that covers an upper surface of an engine-side member of an automobile.

  An engine side member is disposed in the engine room of the automobile. The engine-side member is formed by integrating members such as an engine and a cylinder head cover. The upper surface of the engine side member is generally covered with an engine cover. The engine cover covers the engine side member to enhance the design of the engine room, and blocks or attenuates noise emitted from the engine to the outside. The engine cover is designed in various shapes according to the shape of the engine side member, the shape of the engine room, and the like. By the way, when arranging a tower bar in an engine room, for example, an engine cover may be constituted by a plurality of divisions. This is because the engine cover can be easily attached to and detached from the engine side member.

  By the way, when an engine cover is comprised by several divisions, when an engine cover is attached to an engine side member, a level | step difference may arise in the joint of divisions. If a step occurs at the joint between the split bodies, the split bodies cannot be arranged flush with each other, and the design of the engine room may deteriorate. In addition, when the engine cover vibrates due to vibrations transmitted from the engine or vibrations generated when the vehicle travels, the end of one split hits the end of the other split at the joint, resulting in noise. May occur.

  Patent Document 1 introduces an assembly structure of split bodies on a trunk side composed of a plurality of split bodies. In the assembly structure of split bodies introduced in Patent Document 1, a step portion is provided at an end portion of one split body, and an engagement hole is provided in the step portion. And the engaging member engaged with this engaging hole is provided in the edge part of the other division. According to this technique, the level | step difference produced in the joint of two divisions can be reduced.

However, the assembly structure of the split bodies introduced in Patent Document 1 requires a relatively wide space for the assembly work. On the other hand, the engine cover is disposed in an engine room which is a narrow space. For this reason, when this technology is diverted to the engine cover, there is a problem that the assembly work efficiency deteriorates. Further, when the two segments are made of a hard material, there is also a problem that noise is still generated at the joint between the segments when the engine cover vibrates.
