Description

  The present invention relates to an engine cover that covers an engine member of a vehicle.

  The engine cover is a member that covers an engine member including an engine, a cylinder head cover, and the like, and reduces noise leaking from the engine member to the outside. The engine cover is generally composed of a cover body, a sound absorbing member, and a grommet (see, for example, Patent Document 1). An exploded perspective view schematically showing a general engine cover and engine members is shown in FIG. 6, and a conventional engine cover mounting structure will be described below.

  A general engine cover 101 includes a cover member 102, a grommet 104, and a sound absorbing member 106. The cover member 102 includes a cover portion 120 that covers the engine member 109 and an attachment portion 130 that is formed to protrude on the back surface 121 side of the cover portion 120. The attachment part 130 has a hollow shape. The grommet 104 is attached to the attachment portion 130 by being partially inserted into the attachment portion 130. The sound absorbing member 106 is disposed on the back surface 121 side of the cover part 120. The engine member 109 (or another member disposed in the vicinity of the engine member 109) is provided with a mounting protrusion 190. The engine cover 101 is directly or indirectly attached to the engine member 109 by inserting the attachment protrusion 190 into the grommet 104.

  By the way, as described above, the cover member 102 has the mounting portion 130 protruding so that the sound absorbing member 106 is disposed avoiding the mounting portion 130. Specifically, the sound absorbing member 106 is provided with a through-hole-shaped opening 162, and the attachment portion 130 is inserted through the opening 162. For this reason, the sound absorbing member 106 is not disposed inside the attachment portion 130. Therefore, part of the noise leaked to the outside from the engine member 109 has leaked to the outside of the engine cover 101 through the inside of the mounting portion 130. For this reason, the engine cover 101 which can further reduce noise is desired.

  In addition, it is difficult to suppress the displacement of the sound absorbing member 106 with respect to the cover member 102 only by inserting the attachment portion 130 into the opening 162 of the sound absorbing member 106. For example, when a thermoplastic resin (such as PET) is selected as the material of the sound absorbing member 106, the sound absorbing member 106 can be welded to the resin cover member 102 by a method such as ultrasonic welding, and the sound absorbing member 106 is covered with the cover member. 102 can be fixed. However, when a thermosetting resin is selected as the material of the sound absorbing member 106, the sound absorbing member 106 cannot be welded to the cover member 102. For example, urethane foam (foamed polyurethane) is a material having excellent sound absorption characteristics, but cannot be welded to the cover member 102 because it is a kind of thermosetting resin. For this reason, conventionally, the fixing protrusion 180 provided on the cover member 102 is inserted into the fixing opening 181 provided on the sound absorbing member 106, and a star washer (so-called chrysanthemum washer) 183 is provided at the tip of the fixing protrusion 180. The sound absorbing member 106 is fixed to the cover member 102 by being attached. However, in this case, there is a problem that the number of parts of the engine cover 101 increases, and the work man-hours (assembly man-hours) for assembling the cover member 102, the grommet 104, and the sound absorbing member 106 increase.

Example 1
The engine cover of the first embodiment is attached to a cylinder head cover of a vehicle and covers the upper surface of the engine member. The engine cover of the first embodiment includes the above (2), (3), and (5). FIG. 1 is an exploded perspective view schematically showing the engine cover of the first embodiment. FIG. 2 shows an enlarged cross-sectional view of a main part schematically showing a state in which the engine cover of Example 1 is cut along a plane extending in the up, down, left and right directions in FIG. Hereinafter, in this specification, the terms “up,” “down,” “left,” “right,” “front,” and “rear” refer to “upper, lower, left, right, front, and rear” shown in FIG.

  The engine cover 1 according to the first embodiment includes a cover member 2, a grommet 4, and a sound absorbing member 6. The cover member 2 has a cover part 20 and four attachment parts 30. The cover member 2 is made of PA, and the cover portion 20 and the attachment portion 30 are integrally formed by injection molding. The cover part 20 has a substantially plate shape. Each attachment portion 30 has substantially the same shape, and protrudes outward (in detail, downward in FIG. 1) from the back surface 21 of the cover portion 20. Each mounting portion 30 has a hollow shape and has an opening 31 on a side surface. Specifically, each mounting portion 30 has a top wall 32 and a side wall 33 having a substantially U-shaped cross section. The top wall 32 of each mounting portion 30 has a holding groove 34. The side walls 33 of the two attachment portions 30 open leftward, and the opening 31 faces leftward. The holding grooves 34 of the two attachment portions 30 are also opened leftward. The side walls 33 of the other two attachment portions 30 open to the right, and the opening 31 faces to the right. The holding grooves 34 of the two attachment portions 30 are open to the right.

  The upper part of the grommet 4 which will be described later is inserted into the holding groove 34, and the peripheral part (referred to as the peripheral engaging part 35) of the holding groove 34 in the top wall 32 is engaged with the annular groove 41 of the grommet 4 which will be described later. Yes. Two ribs 36 extending from the lower part of the side wall 33 toward the upper part are formed on the side wall 33 of the attachment part 30. The ribs 36 are spaced apart from each other and project from the side surface of the mounting portion 30 toward the outer peripheral side (from the outer peripheral surface of the side wall 33 toward the outer peripheral side of the side wall 33). The rib 36 corresponds to a cover engaging portion in the present invention.

  The grommet 4 is made of rubber and has a substantially cylindrical shape. Specifically, the outer circumferential surface 40 of the grommet 4 is formed with an annular groove 41 that engages with the peripheral edge engaging portion 35 described above. Inside the grommet 4, an engagement hole portion 42 that extends in the axial direction of the grommet 4 and forms a groove shape is formed. An attachment projection 90 is formed on the cylinder head cover 9. The head 91 of the attachment projection 90 is inserted into the engagement hole 42. The engagement hole 42 engages with the head 91 of the attachment protrusion 90.

  The sound absorbing member 6 is made of urethane foam, and has a sound absorbing general portion 60 having a substantially plate shape and four sound absorbing mounting portions 61 having a substantially columnar shape. The sound absorbing general portion 60 has a through-hole-shaped opening 62 at a position corresponding to each attachment portion 30. In addition, a slit-like sound absorption engagement portion 63 is formed at a position corresponding to the rib 36 of the attachment portion 30 on the peripheral edge portion of the opening 62 in the sound absorption general portion 60. The opening diameter of each opening 62 is slightly smaller than the outer diameter of the corresponding attachment portion 30. Each sound absorbing portion 61 is disposed inside each opening 62. The height of each sound absorbing mounting portion 61 (the length of the sound absorbing general portion 60 in the thickness direction) is larger than the thickness of the sound absorbing general portion 60. Accordingly, each of the sound absorbing attachment portions 61 extends downward from the sound absorbing general portion 60. Each sound absorbing attachment portion 61 has a base portion 64 and an extension portion 65. The extension portion 65 is continuous with the lower side of the base portion 64. The base portion 64 is a portion that is inserted into the upper side of the mounting portion 30, and the extension portion 65 is a portion that is inserted into the lower side of the mounting portion 30. The extending portion 65 has a standing wall shape extending along the outer peripheral side portion of the base portion 64. Therefore, the radial cross section of the extending portion 65 (cross section cut along a plane extending in the front-rear and left-right directions in FIG. 1) is substantially U-shaped. The base 64 has a surface facing the side wall 33 of the mounting portion 30 (first surface 66) and a surface facing the opening 31 of the mounting portion 30 (second surface 67). The first surface 66 is not curved, and the second surface 67 is substantially planar. The upper part of the second surface 67 and the sound absorbing general part 60 are integrated. A substantially U-shaped slit 68 is formed between the first surface 66 and the sound absorbing general portion 60. The outer diameter of the base portion 64 (the circumferential length of the first surface 66) is slightly larger than the inner diameter of the lower portion of the attachment portion 30. The outer diameter of the extension part 65 is slightly larger than the inner diameter of the upper part of the attachment part 30. The inner diameter of the extension portion 65 is slightly smaller than the outer diameter of the grommet 4.

  The procedure for assembling the cover member 2, the grommet 4, and the sound absorbing member 6 in the engine cover 1 of the first embodiment is as follows.

  First, the sound absorbing member 6 is attached to the cover member 2. At this time, the mounting portion 30 of the cover member 2 is inserted into the opening 62 of the sound absorbing member 6 while the sound absorbing mounting portion 61 of the sound absorbing member 6 is bent toward the first surface 66 side to expose the opening 62. Then, the sound absorbing member 6 is slid toward the cover member 2. Then, as shown in FIG. 2, the sound absorbing general part 60 contacts the back surface 21 of the cover part 20. At this time, the rib 36 is inserted into the sound absorbing engagement portion 63. Next, the sound absorbing attachment portion 61 is inserted into the attachment portion 30. The sound absorbing mounting portion 61 is easily inserted into the mounting portion 30 due to elasticity. Therefore, the peripheral edge portion of the mounting portion 30 on the back surface 21 of the cover portion 20 is covered with the sound absorbing general portion 60, the sound absorbing mounting portion 61 is inserted inside the mounting portion 30, and the side wall 33 of the mounting portion 30 is the sound absorbing member 6. It is sandwiched between the slits 68. As described above, the outer diameter of the base portion 64 and the outer diameter of the extension portion 65 are slightly larger than the inner diameter of the attachment portion 30, so that the sound absorbing attachment portion 61 (base portion 64 and extension portion 65) is attached to the attachment portion 30. Press contact with the inner surface (inner peripheral surface). Moreover, since the opening diameter of each opening 62 in the sound absorbing member 6 is slightly smaller than the outer diameter of the corresponding mounting portion 30, the sound absorbing general portion 60 is in pressure contact with the outer surface (outer peripheral surface) of the mounting portion 30.

  Next, the grommet 4 is attached to the cover member 2. Specifically, the grommet 4 is disposed on the opening 31 side of the attachment portion 30, and the annular groove 41 is opposed to the peripheral engagement portion 35. Then, the grommet 4 is slid toward the attachment portion 30. Then, the annular groove 41 of the grommet 4 engages with the peripheral edge engaging portion 35 of the attachment portion 30 (specifically, the top wall 32). The upper part of the grommet 4 is inserted into the mounting part 30, and the lower part of the grommet 4 is exposed to the lower side of the mounting part 30 through the holding groove 34. At this time, the extending portion 65 is sandwiched between the grommet 4 and the inner surface of the mounting portion 30 (specifically, the inner surface of the side wall 33). Therefore, the extension part 65 in the engine cover 1 of Example 1 is equivalent to the 2nd clamping part in this invention. Since the inner diameter of the extension part 65 is slightly smaller than the outer diameter of the grommet 4, the extension part 65 comes into pressure contact with the grommet 4. In the engine cover 1 of the first embodiment, the lower surface of the base portion 64 and the top surface (upper surface) of the grommet 4 are not in contact with each other.

  In the engine cover 1 of the first embodiment, the back surface of the portion located outside the mounting portion 30 in the cover portion 20 is covered with the sound absorbing general portion 60. In addition, a sound absorbing mounting portion 61 that is a part of the sound absorbing member 6 is inserted into the mounting portion 30. For this reason, the sound absorbing member 6 covers not only the part located outside the attachment part 30 in the cover part 20 but also the part located inside the attachment part 30. Therefore, according to the engine cover 1 of the first embodiment, the noise that has reached the inside of the attachment portion 30 can be absorbed by the sound absorption attachment portion 61, and the noise that leaks out of the engine cover 1 through the inside of the attachment portion 30 can be suppressed.

  Further, a portion of the back surface 21 of the cover portion 20 located inside the attachment portion 30 is covered with the sound absorbing attachment portion 61 without any defects. The outer peripheral edge portion of the attachment portion 30 on the back surface 21 of the cover portion 20 is covered with the sound absorbing general portion 60 without any defects. For this reason, according to the engine cover 1 of Example 1, the noise generated by the engine member can be absorbed with high reliability.

  Furthermore, the extension part 65 (that is, the second sandwiching part in the engine cover of the present invention) that is a part of the sound absorbing attachment part 61 includes the side wall 33 of the attachment part 30 that is a part of the cover member 2 and the grommet 4. , Is sandwiched between. For this reason, the sound absorbing member 6 is fixed to the cover member 2 and is not easily displaced with respect to the cover member 2. Moreover, since the cover member 2, the sound absorbing member 6, and the grommet 4 are assembled in a very simple process, an increase in the number of assembling steps can be suppressed.

  Furthermore, although the sound absorbing member 6 made of urethane foam is used, since no other member is required when the cover member 2, the sound absorbing member 6 and the grommet 4 are assembled, excellent sound absorbing without increasing the number of parts. The effect is demonstrated.

  Further, in the engine cover 1 of the first embodiment, the rib 36 of the attachment portion 30 is inserted into the sound absorbing engagement portion 63 of the sound absorbing member 6, and the rib 36 and the sound absorbing engagement portion 63 are engaged. Therefore, according to the engine cover 1 of the first embodiment, the sound absorbing member 6 can be firmly fixed to the cover member 2.

  Furthermore, since the lower surface of the base portion 64 and the top surface (upper surface) of the grommet 4 are not in contact with each other, when the grommet 4 is attached to the attachment portion 30, frictional resistance between the grommet 4 and the base portion 64 does not occur. Therefore, the engine cover 1 of Example 1 is further excellent in attachment workability.

(Example 2)
The engine cover of the second embodiment is the same as the engine cover of the first embodiment except that the sound absorbing general portion before assembly does not have a sound absorbing engagement portion and the shape of the sound absorbing mounting portion. The engine cover of the second embodiment includes the above (1), (3), and (5). FIG. 3 shows an enlarged cross-sectional view of a main part schematically showing a state in which the engine cover of Example 2 is cut at the same position as FIG.

  The sound absorbing mounting portion 61 in the engine cover 1 of the second embodiment does not have the extending portion 65 and is configured by only the base portion 64. The height of the base portion 64 in the engine cover 1 of the second embodiment is higher than the height of the base portion 64 in the engine cover 1 of the first embodiment, and the lower surface of the base portion 64 is the top surface 45 ( It is in contact (pressure contact) with the top surface. For this reason, the sound absorbing mounting portion 61 in the engine cover 1 of the second embodiment is sandwiched between the cover portion 20 and the grommet 4. Specifically, the base portion 64 is sandwiched between the back surface 21 (lower surface) of the cover portion 20 located inside the mounting portion 30 and the top surface 45 of the grommet 4. Therefore, the base 64 in the engine cover 1 of the second embodiment corresponds to the first clamping portion in the engine cover of the present invention. For this reason, the sound absorbing member 6 in the engine cover 1 of the second embodiment is fixed to the cover member 2 similarly to the sound absorbing member 6 in the engine cover 1 of the first embodiment.

  Further, a sound absorbing mounting portion 61 is disposed inside the mounting portion 30, and the sound absorbing mounting portion 61 is in pressure contact with the inner side surface of the mounting portion 30. Therefore, the back surface 21 (lower surface) of the cover portion 20 located inside the mounting portion 30 is covered with the sound absorbing mounting portion 61 without any defects. For this reason, the engine cover 1 according to the second embodiment can reduce noise leaking to the outside of the engine cover 1 through the inside of the mounting portion 30, similarly to the engine cover 1 according to the first embodiment.

  Further, the mounting portion 30 in the engine cover 1 of the second embodiment has a rib 36 (cover engaging portion), similarly to the mounting portion 30 in the engine cover 1 of the first embodiment. However, the sound absorbing general portion 60 in the engine cover 1 of the second embodiment does not have the sound absorbing engaging portion 63 in a state before being assembled to the cover member 2. In the engine cover 1 of the second embodiment, when the sound absorbing member 6 is assembled to the cover member 2, the peripheral edge portion of the opening 62 in the sound absorbing general portion 60 is cut by the rib 36 and shaped into a shape corresponding to the rib 36. . In other words, the sound absorbing engagement portion 63 in the engine cover 1 of the second embodiment is formed when the sound absorbing member 6 is assembled to the cover member 2. For this reason, the sound absorbing member 6 in the engine cover 1 of the second embodiment is firmly fixed to the cover member 2 in the same manner as the sound absorbing member 6 in the engine cover 1 of the first embodiment.

  In addition, you may provide the extension part 65 similar to the engine cover of Example 1 in the sound absorption attaching part 61 in the engine cover 1 of Example 2. FIG. In this case, the base portion 64 (first sandwiching portion) is sandwiched between the back surface 21 of the cover portion 20 and the top surface 45 of the grommet 4, and the extension portion 65 (second sandwiching portion) is the side wall of the mounting portion 30. 33 and the outer peripheral surface 40 of the grommet 4. Therefore, in this case, the sound absorbing member 6 is more firmly fixed to the cover member 2.

(Example 3)
The engine cover of the third embodiment is the same as the engine cover of the first embodiment except that the mounting portion does not have a rib, the sound absorbing general portion does not have a sound absorbing engaging portion, and the shape of the sound absorbing mounting portion. . The engine cover of the third embodiment includes the above (2), (4), and (5). FIG. 4 shows an enlarged perspective view of a main part schematically showing a sound absorbing member in the engine cover of the third embodiment. FIG. 5 shows an enlarged cross-sectional view of a main part schematically showing a state where the engine cover of the third embodiment is cut at the same position as that in FIG.

  As shown in FIGS. 4 and 5, the height of the sound absorbing portion 61 in the engine cover 1 of the third embodiment is approximately the same as the thickness of the sound absorbing general portion 60. A sound absorbing engagement portion 63 having a through hole shape is formed inside the sound absorbing mounting portion 61. The grommet 4 is inserted into the sound absorbing engagement portion 63. The peripheral edge portion of the sound absorbing engagement portion 63 and the outer peripheral surface 40 of the grommet 4 are in pressure contact. Therefore, the sound absorbing engagement portion 63 and the outer peripheral surface 40 of the grommet 4 are engaged.

  In the engine cover 1 according to the third embodiment, a portion of the back surface 21 of the cover portion 20 that is located inside the sound absorbing mounting portion 61 is covered with the sound absorbing mounting portion 61 and the grommet 4 without any problems. For this reason, the noise that has reached the inside of the attachment portion 30 is sound-insulated by the grommet 4 and is absorbed by the sound absorption attachment portion 61. Therefore, the engine cover 1 of the third embodiment can also suppress noise leaking through the attachment portion 30 and out of the engine cover 1.

  As shown in FIGS. 4 and 5, the portion 69 located on the opposite side of the opening 31 of the mounting portion 30 in the sound absorbing mounting portion 61 is sandwiched between the side wall 33 of the mounting portion 30 and the grommet 4. For this reason, the sound absorbing member 6 in the engine cover 1 of the third embodiment is fixed to the cover member 2 similarly to the sound absorbing member 6 in the engine cover 1 of the first and second embodiments.

  Further, the sound absorbing member 6 is fixed to the engine member (cylinder head cover 9) via the grommet 4 because the sound absorbing engaging portion 63 and the outer peripheral surface 40 of the grommet 4 are engaged. For this reason, the sound absorbing member 6 in the engine cover 1 of the second embodiment is firmly fixed to the cover member 2 similarly to the sound absorbing member 6 in the engine cover 1 of the first and second embodiments.

  In addition, although the sound absorption engaging part 63 in the engine cover 1 of Example 3 makes a through-hole shape, you may make other concave shapes, such as a dead end hole shape. Also in this case, if the grommet 4 is inserted into the sound absorption engagement portion 63 and the sound absorption engagement portion 63 and the outer peripheral surface 40 of the grommet 4 are engaged, the sound absorption member 6 is covered with the cover member via the grommet 4. 2 can be firmly fixed.
