[Industrial applications]

 The present invention relates to an engine service cover, and more particularly to an engine service cover that is lightweight and has a reduced number of parts.

[0002]

[Prior art]

 Conventionally, engine service covers have been used for vehicles such as minibuses and one-box cars where the engine is under the floor. A conventional example of this engine service cover is shown in FIGS. The engine service cover acts as a cover that isolates the inside and outside of the engine from above and also on the aisle that moves to the driver's seat and passenger seat.Therefore, the engine service cover is rigid enough to prevent people from riding on it. Must be secured. Also, by opening this engine service cover, daily engine service is performed. FIG. 4 is a perspective view showing an assembled state of the conventional example, and FIG. 5 is a sectional view taken along line BB (CC) of FIG. 4 and 5, the engine service cover 6 is attached to the hole 71a of the front floor 71 of the vehicle. The engine service cover 6 consists of two parts 6a and 6b. The structure of each of the portions 6a and 6b is as follows. That is, a lauan board 61 is placed in the middle, and a mat 62 is arranged on the upper side of the board 61. A mat set plate 63 for pressing the end of the mat 62 is fixed to the board 61 with screws 64. An iron panel 65 is attached to the board 61 with screws 66 on the lower side of the board 61, and a glass wool silencer 67 is fixed to the lower side of the panel 65 (engine room side). Further, a weather strip 68 is attached to the peripheral portion of the lower surface of the board 61. The weather strip 68 is a long and narrow rubber sealing material and is used to bring the parts 6a and 6b of the engine service cover 6 into close contact with the edges of the hole 71a of the front floor 71.

[Problems to be solved by the device]

 However, since the engine service cover of the above-mentioned conventional example has a large number of parts, it takes a long time to assemble it, and in particular, it takes a long time to assemble the mat set plate. Further, since the engine service cover of the conventional example is heavy in weight, it is not easy to attach / detach the engine service cover, and further, an iron plate is added to secure its rigidity.

Therefore, an object of the present invention is to provide an engine service cover in which the number of parts is reduced, the number of assembling steps is reduced, and the weight is further reduced in order to eliminate the above-mentioned drawbacks of the conventional example.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the structure of the present invention is a flat engine service cover body made of synthetic resin and having ribs formed on the lower surface, and a metal panel fixed to the lower surface of the engine service cover body. The engine service cover includes a silencer such as glass wool fixed to the lower surface of the metal panel.

[0006]

[Action]

 In the engine service cover having the above structure, a flat plate-shaped engine service cover body made of synthetic resin and having a rib formed on the lower surface secures the rigidity of the engine service cover, and is a metal panel fixed to the lower surface of the engine service cover body. And a silencer such as glass wool fixed to the lower surface of the metal panel blocks heat and noise of the engine arranged under the floor.

[0007]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view showing an assembled state of an embodiment of the present invention, FIG. 2 is a perspective view showing a back surface of the embodiment of the present invention, and FIG. 3 is a partially enlarged sectional view of the embodiment of the present invention. is there. 1 and 2 and 3, in the engine service cover 1, a metal panel 21 is fixed to a lower surface 11b of a rigid plate-shaped engine service cover body 11 having ribs 12 formed on a lower surface 11b of synthetic resin. A silencer 31 such as glass wool is fixed to the lower surface of the metal panel 21, and a cushion 41 is fixed to the peripheral portion of the lower surface 11b of the engine service cover body 11. The engine service cover body 11 is made of glass fiber reinforced plastic (FRP). The rib 12 is integrally formed on the lower surface 11b of the engine service cover body 11, is a part of the engine service cover body 11, and secures the rigidity of the engine service cover body 11. Further, due to the ribs 12, an air layer 51 is formed between the lower surface 11b of the engine service cover body 11 and the panel 21 described later. The pattern 13 formed on the upper surface 11a of the engine service cover body 11 has a large number of circular low protrusions to prevent slippage, and secures the safety of the floor 52 in the vehicle. A hook 15 is formed on the side surface 11c of the engine service cover body 11. The hook 15 is for hooking on a locking tool (not shown) in the vehicle. The metal panel 21 is fixed to the screw holes 14a of a large number of protrusions 14 formed on the lower surface 11b of the engine service cover main body 11 with a screw (not shown) through the mounting holes 21c of the panel 21. Since the ribs 12 formed on the lower surface 11b of the engine service cover body 11 as described above ensure the rigidity of the engine service cover, the thickness of the panel 21 can be reduced. The silencer 31 such as glass wool is attached to the lower surface of the panel 21 in the drawing by inserting a clip 32 into the attachment hole 21a of the panel 21 and the attachment hole 31a of the silencer 31. The rubber cushion 41 is fixed to the screw hole 14a of the protrusion 14 at the peripheral portion of the lower surface 11b of the engine service cover body 11 through the hole 21b of the panel 21 in a screwed manner. Since the cushion 41 supports the engine service cover body 11 on the floor 52 in the vehicle, the weight of the engine service cover 1 and the load of the person when the engine service cover 1 is placed on the floor of the vehicle can be reduced. It plays the role of telling the follower 52.

With the above configuration, when a person rides on the engine service cover 1, the ribs 12 formed on the entire lower surface of the engine service cover body 11 ensure the rigidity of the engine service cover body 11 and provide a cushion. 41 supports the engine service cover body 11 on a floor 52 inside the vehicle. Since the engine service cover 1 is located above the engine (not shown), it is susceptible to heat generated by the engine. It is also necessary to prevent the heat from being transmitted indoors. Therefore, the heat is blocked by the air layer 51 in the gap between the lower surface 11b of the engine service cover body 11 and the panel 21 and the silencer 31. Furthermore, the panel 21 and the silencer 31 also have a structure for insulating and absorbing noise generated from the engine. Further, similarly to the above-mentioned conventional example, the engine service cover 1 is attachable to and detachable from the hole of the floor 52, and can be detached from the hole of the floor 52 as needed.

[Effect of device]

 As described in detail above, according to the engine service cover of the present invention, the number of parts of the engine service cover can be significantly reduced. In particular, the mat set plate of the conventional example and the screw for fixing it to the board can be eliminated. Further, instead of the conventional mat, a pattern is integrally formed on the upper surface of the engine service cover body, so that the mat can be eliminated. Also, by reducing the number of parts, the man-hours for assembling the engine service cover can be reduced. In addition, the engine service cover body is made of synthetic resin, so the engine service cover can be made significantly lighter. In addition, the elimination of the mat set plate improved the appearance of the engine service cover, and the engine service cover itself was made of synthetic resin, creating a sense of unity between the engine service cover and the floor inside the vehicle.
