Problems solved by technology

[0006] With regard to the invention described in Patent Document 1, in order to obtain sufficient strength by the inner reinforcing plate, the cover body structure becomes heavy, and the weld marks are easily exposed to the outside.
In addition, the sound insulation performance and sound absorption performance are insufficient
[0007] Regarding the invention described in Patent Document 2, when the engine cover is opened, the inner lining parts such as the sound absorbing material can be seen from the outside, so it is unsightly and cannot obtain sufficient strength

Embodiment Construction

[0036] Refer below Figure 1 to Figure 7 An embodiment is shown to illustrate the invention in detail.

[0037] Such as Figure 4 As shown, a hydraulic excavator 10 as mechanical equipment is provided with an upper revolving body 12 that can rotate relative to a lower traveling body 11, and a cab 13 and a working device 14 are mounted on the upper revolving body 12, and an engine is mounted thereon. 15 and the air filter, radiator, etc. associated with the engine 15, the engine 15 is covered by the engine cover 16, and the air filter and radiator are covered by double-opening side door panels (hereinafter referred to as panels) 17,18. Figure 5 Denotes the plate 17 on the air filter side, Image 6 Plate 18 on the radiator side is indicated.

[0038] figure 1 It is an enlarged view of a part of these plates 17, 18. These plates 17, 18 have: an outer thin plate 21; an inner thin plate 23 fixed to the inner surface of the outer thin plate 21 and forming a space 22; foam mat...

Abstract

The invention provides a panel and a manufacturing method, wherein the panel realizes satisfactory strength, weight reduction and acoustic performance. Panel (17,18) has cavity (22) defined by inside thin sheet (23) fixed to the inside surface of outside thin sheet (21), and the cavity (22) is filled with foam (24). Preferably, the foam (24) consists of a rubber acoustic material of high expansion. For the inside thin sheet (23), not only circumferential edge portion (26) and circumferential side portion (25) for defining the cavity (22) but also recessed portion (27) for increasing the panel strength is draw formed on the side of outside thin sheet (21). The bottom surfaces of the circumferential edge portion (26) and recessed portion (27) of the inside thin sheet (23) are bonded to the outside thin sheet (21) by a thermosetting adhesive.

Description

technical field [0001] The present invention relates to a panel with foamed material and a method for its manufacture. Background technique [0002] There is a cover structure in which an inner reinforcing plate having a concave portion is welded to an outer plate of a construction machine (for example, refer to Patent Document 1). [0003] Also, in construction machines, there is an engine cover in which a sound insulating material or a sound absorbing material is attached as a lining member inside a cover main body (for example, refer to Patent Document 2). [0004] Patent Document 1: Japanese Patent Application Laid-Open No. 9-228412 (page 3, Figure 7 ) [0005] Patent Document 2: Japanese Patent No. 3457804 (page 2, figure 1 ) [0006] In the invention described in Patent Document 1, in order to obtain sufficient strength by the inner reinforcing plate, the cover body structure becomes heavy, and welding traces tend to be exposed to the outside. In addition, sound ...
