Problems solved by technology

[0009] However, in the technology disclosed in Patent Document 2, in the assembled state, since the circular fitting neck portion fits into the substantially triangular mounting hole, the posture of the rubber damper tends to become unstable, and the rubber damper may become unstable. Shock absorber falls out of mounting hole

Embodiment approach 1

[0039]The engine cover 1 according to the present embodiment shown in FIGS. 1 to 4 has: a cover main body portion 1; a mounting seat plate portion 20 integrally provided on the cover main body portion 10; and three mounting seats (not shown). As shown in the figure), they are integrally provided on the cover main body 10. The cover main body portion 10, the mounting seat plate portion 20, and the three mounting seats are integrally formed by injection molding of synthetic resin such as PP (polypropylene) or PA (nylon).

[0040] As shown in FIG. 1 , the cover body 10 has a substantially quadrangular tray shape. On the cover main body 10 , a mounting seat plate portion 20 is provided near one of the four corners, and mounting seats (not shown) are arranged at the other three positions of the four corners. In addition, three mounts are integrally provided on the rear surface of the cover main body 10 .

[0041] The mounting seat plate portion 20 is provided in a cantilever shap...

Embodiment approach 2

[0060] In this embodiment shown in FIG. 5 , the shape of the circular mounting hole 30 is changed.

[0061] That is, the circular mounting hole 30 on the engine cover 1 according to the present embodiment has, as in the first embodiment described above, a pair of arc-shaped fitting recesses 31, 31 which face each other in the radial direction; The relief recesses 32, 32 are radially opposite. In addition, at the boundary between each arc-shaped fitting recessed portion 31 and each relief recessed portion 32 , instead of the aforementioned corner portion 33 , a curved surface portion 34 is formed, respectively.

[0062] Thus, if the curved surface portion 34 is formed instead of the corner portion 33, it is considered that the degree of freedom and deformation amount of the locking head portion 43 pressed into the circular mounting hole 30 increase. Therefore, the ease of assembly of the rubber mount 40 with respect to the circular mounting hole 30 can be further improved.

other Embodiment approach

[0065] In addition, in Embodiment 1 or 2 above, it has been described that the mounting seat plate portion 20 provided in the shape of a cantilever beam at the side end portion of the engine cover 1 is formed in a circular shape having the arc-shaped engagement recess 31 and the relief recess 32 . An example of the installation hole 30, but the present invention is not limited thereto. For example, a circular mounting hole 30 having an arcuate engagement recess 31 and a relief recess 32 may be formed in the mounting seat plate portion of the mounting seat provided on the back surface of the engine cover 1 .

[0066] Also, the number of mounting seat plate portions forming the circular mounting hole 30 having the arcuate engagement recess 31 and the relief recess 32 is not limited in the engine cover 1 , and may be one or plural.

[0067]In addition, in the circular mounting hole 30, the number and size of the arc-shaped engagement recesses 31 and the relief recesses 32 are not...

Abstract

The invention provides an engine hood, which ensures the strength of a soleplate integrally arranged on the engine hood, and increases the assembling facility of the rubber mount relative to the mounting hole. The engine hood (1) has a hood main body (10); an assembling base plate (20), integrally arranged on the hood main body (10) and impenetrated with circular mounting holes (30); and a rubber mount assembled and kept in the circular mounting holes (30), which include the following parts: at least a circular tabling trough (31), with a corresponding arc with the tabling neck of the rubber mount; and a conceding trough (32) arranged at least one position of the circumference of the circular mounting holes (30). When the conceding trough (32) performs the assemble of the rubber mount relative to the circular mounting holes (30), the head part of the rubber mount is partly entered.

Description

technical field [0001] The present invention relates to an engine cover for covering an engine, and more particularly, to an engine cover in which the structure of a mounting portion attached to an engine is improved. Background technique [0002] An engine cover is attached to a vehicle engine to, for example, cover the upper surface of a cylinder head to prevent noise leaking from the engine or to improve the appearance of the engine room. The engine cover is attached to, for example, pins, bolts, etc. protruding from the engine side (for example, refer to Patent Document 1). [0003] In the engine cover mounting structure disclosed in Patent Document 1, a mounting seat is integrally provided on the rear surface of the engine cover, and a rubber mount having an engaging recess is assembled and held on the mounting seat. And, the engine cover is attached to the engine body by pressing the pin protrudingly provided on the engine body side into the engagement recess of the r...
