Abstract

The utility model relates to a key cover device of a digital piano, in particular to a cover turning device of the digital piano, comprising a front key cover, a rear key cover, a key cover hinge, a key cover long hinge, a key cover guide rail and a key cover wheel, wherein the front key cover and the rear key cover are connected through the key cover long hinge; and the rear key cover is fixed with the key cover wheel which can slide on the key cover guide rail at the rear part of a keyboard. When a user turns up the front key cover, the key cover hinge rotates around a rotating shaft, the front key cover drives the rear key cover to move through the key cover long hinge, and the rear key cover moves along the key cover guide rail. The adoption of the cover turning device leads the keyboard of the digital piano to have the appearance close to that of the traditional piano and also no need of large width in an opening state, and the cover turning device has simple structure and scientific and reasonable design.

Description

A kind of digital piano overthrow lid arrangement

[technical field]

The utility model relates to a kind of key cap assembly of digital piano, relates in particular to a kind of lid arrangement of overthrowing of digital piano.

[background technology]

Digital piano is a kind of electrophonic musical instrument, is used for replacing in some occasion the electrophonic musical instrument of traditional piano.At present, the popularity rate of digital piano is more and more higher, and the tone color of digital piano is also more and more near traditional piano.But because digital piano Duo a control panel than traditional piano, so digital piano key lid general employing pushing cover or renovate dual mode at present.And traditional piano generally is to adopt to renovate form, so digital piano just has certain gap with traditional piano in appearance when adopting pushing cover, and key covers than broad, push in fully need qin width than broad.If adopt and to renovate, because the key lid is wideer than the key lid of traditional piano, very big difference is still arranged, and influence acoustics during tip-up state so dig the effect and the traditional piano that come.

[summary of the invention]

At the problems referred to above, the purpose of this utility model provides a kind of digital piano keyboard that makes when open mode, both, do not need very big width near the outward appearance of traditional piano yet, and can not influence digital piano acoustic digital piano overthrow lid arrangement.

For achieving the above object, technical solution adopted in the utility model is as follows:

A kind of digital piano overthrow lid arrangement, key lid, back key lid, key lid hinge, key lid band andgudgeon chain, key lid guide rail and key lid wheel before comprising, key lid hinge is positioned at an end of preceding key lid and covers at preceding key by screw retention, preceding key lid is connected by key lid band andgudgeon chain with back key lid, one end of back key lid has key lid wheel by screw retention, key lid guide rail is positioned at the rear portion of keyboard, and key lid wheel can cover to cooperate on the guide rail and slide at key.

The low domatic in high back before described key lid guide rail is.

The utility model is fixed key lid hinge owing to covering at preceding key, with key lid band andgudgeon chain preceding key lid and back key lid is coupled together, and back key covers the Gu Dingyijiangai wheel, and the key lid is taken turns and can be slided on the key lid guide rail at keyboard rear portion.When key covered before the user digs, key lid hinge was rotated around turning axle, and preceding key lid covers the band andgudgeon chain by key and drives back key lid motion, and back key covers along key lid guide rail movement.Owing to adopt this lid arrangement of overthrowing, make the digital piano keyboard when open mode, both, do not need very big width near the outward appearance of traditional piano yet; Back key lid moves on key lid guide rail by key lid wheel, the noise that brings in the time of can effectively reducing back key lid motion, and the low domatic in high back before key lid guide rail is when assembling can prevent effectively when keyboard opens fully that like this key lid from turning over forward.

[description of drawings]

Fig. 1 is the structural representation reference diagram of the utility model when covering.

Fig. 2 is the structural representation reference diagram of the utility model in opening procedure.

Fig. 3 is the structural representation reference diagram of the utility model when opening fully.

Fig. 4 is applied in a kind of status architecture signal reference diagram on the digital piano for the utility model.

Fig. 5 is applied in another user mode structural representation reference diagram on the digital piano for the utility model.

Among the figure, 1 is that key lid after preceding key lid, 2 is, 3 is that key lid take turns for key covers band andgudgeon chain, 5 for key builds guide rail, 6 for key covers hinge, 4.

[embodiment]

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Shown in accompanying

drawing

1,2 and 3, a kind of digital piano overthrow lid arrangement, key lid 1, back key lid 2, key lid hinge 3, key lid band andgudgeon chain 4, key lid guide rail 5 and key lid wheel 6 before comprising, key lid hinge 3 is covered on 1 at preceding key by screw retention, before key lid 1 is connected by key lid band andgudgeon chain 4 with back key lid 2, an end of back key lid 2 has a key to cover by screw retention to take turns 6, key covers the rear portion that guide rail 5 is positioned at keyboard, the low domatic in high back before being, key lid wheel 6 can cover to cooperate on the guide rail 5 and slide at key.

During use, key lid 1 before digging, key lid hinge 3 will be rotated around turning axle, preceding key lid 1 drives the back key by key lid band andgudgeon chain 4 and covers 2 motions, back key lid 2 covers on the guide rail 5 slowly to lower slider at key by key lid wheel 6, when back key lid 2 slides into the bottom of key lid guide rail 5, the lid of overthrowing of digital piano can be opened and used fully; When needs cover, key lid 1 before turning down, key lid hinge 3 is rotated around turning axle, preceding key lid 1 drives the back key by key lid band andgudgeon chain 4 and covers 2 motions, back key lid 2 slowly upwards slides on key lid guide rail 5 by key lid wheel 6, when back key lid 2 slides into the top of key lid guide rail 5, can cover the keyboard of digital piano.Back key lid 2 covers wheel 6 motion on key lid guide rail 5 by key, has effectively reduced the noise that brings when back key lid 2 moves; The low domatic in high back before key lid guide rail 5 is when assembling, the key lid can prevent effectively when opening fully that the key lid from turning over forward.

A kind of digital piano of the utility model overthrow lid arrangement, make the digital piano keyboard when open mode, both, do not need very big width yet, and can not influence the acoustics of digital piano near the outward appearance of traditional piano, simple in structure, design science is reasonable.
