Referring to fig. 1 to 5, this embodiment discloses a musical instrument lid buffer structure, including apron 1, box body 2, buffer 3, buffering arm 4 and magnetic path 5, apron 1 articulates in the upper portion of box body 2, and apron 1 can upwards and overturn downwards relative to box body 2, and buffer 3 connects in box body 2 is inside, and buffering arm 4 connects in buffer 3, and magnetic path 5 is fixed in buffering arm 4, and apron 1 butt with buffering arm 4 during the upset downwards and inhale mutually with magnetic path 5.

It should be noted that, when the cover plate 1 is in a normal open state, the cover plate 1 may contact with the buffer arm 4 or not contact with the buffer arm 4, when the cover plate 1 is turned down, the cover plate may be connected with the buffer arm 4 all the time in the whole process of turning down, or may be connected with the buffer arm 4 after turning down to a certain stroke, in a word, before the cover plate 1 is closed, the cover plate 1 contacts with the buffer arm 4, and as the cover plate 1 is gradually turned down, the opening angle becomes smaller and smaller, the cover plate 1 drives the buffer arm 4 to rotate, the rotation direction of the buffer arm 4 is the same as the turning down direction of the cover plate 1, and in this rotation direction, the buffer arm 4 rotates more and more toward the direction of the large resistance of the buffer 3, so that the damping effect of the buffer 3 is good, the resistance fed back to the cover plate 1 becomes larger and larger, that the cover plate 1 is closer to the closed state, the closing speed is slower, and the hands of a player are protected from being pinched during the closing process, it has enough time handle to move out from the keyboard, avoids taking place the incident.

With reference to fig. 3 to 5, in this embodiment, the bottom of the cover plate 1 is connected with the connecting arm 6, the connecting arm 6 is provided with the connecting shaft 7, the connecting shaft 7 is used for abutting against the buffer arm 4, and an auxiliary structure for facilitating the stress of both sides can be arranged between the connecting shaft 7 and the buffer arm 4, that is, when the cover plate 1 is turned down, the stress is transferred by the contact between the connecting shaft 7 and the buffer arm 4, and the stress is more uniform and effective.

Furthermore, the connecting arm 6 is L-shaped, the front end of the connecting arm 6 is connected with the cover plate 1, the rear end of the connecting arm 6 extends to one side facing the buffer 3, the connecting shaft 7 is welded at the rear end of the connecting arm 6, and when the cover plate 1 is turned over, the connecting shaft 7 at the rear end of the connecting arm 6 and the buffer arm 4 are driven to generate stress and displacement changes.

As an implementation mode, the connecting arm 6 is made of a magnetic metal material, the magnetic block 5 and the connecting arm 6 are attracted magnetically, and the strong magnetic attraction between the magnetic block 5 and the connecting arm 6 is utilized to further improve the connecting force between the connecting arm 6 and the buffer arm 4, so that the connecting arm 6 and the buffer arm are always in contact in the buffer effective stroke, and the cover closing impact force is reduced.

In this embodiment, the buffer 3 is a one-way buffer 3, the buffering direction of the buffer 3 is the downward-turning direction of the cover plate 1, that is, when the cover plate 1 is opened, the buffer 3 generates a buffering damping effect, and when the cover plate 1 is opened, the buffer 3 does not provide resistance to the cover plate 1, so that the cover is opened quickly.

As an implementation mode, the cover plate 1 is in the downward overturning process, pass through a free overturning stroke before the butt with the buffer arm 4, namely at the initial stage of the cover plate 1 closing process, because the cover plate 1 is greater from the opening angle of the box body 2, the hand clamping accident can not be generated at this moment, in this section of free overturning stroke, the connecting arm 6 is not in contact with the buffer arm 4, the buffer 3 does not generate the damping effect, after the free overturning stroke is completed, the connecting arm 6 is in contact with the buffer arm 4, and the magnetic block 5 also generates the magnetic attraction effect, the cover plate 1 is overturned again at this moment, the buffer 3 generates the buffering damping effect, so that the damping effect arrangement of the whole cover closing process of the cover plate 1 is more reasonable, the cover plate 1 is freely overturned in the first half, the cover plate 1 is slowly overturned in the second half, namely, the cover closing timeliness is ensured, and the cover closing safety is ensured.

In some embodiments, while the connecting shaft 7 abuts against the buffer arm 4, the connecting arm 6 is in contact with the magnetic block 5, that is, the connecting arm 6 is in direct contact with the magnetic block 5 to maintain the state of magnetic attraction; in contrast, in the process of closing the cover plate 1, although the magnetic force between the magnetic block 5 and the connecting arm 6 is kept to attract each other, the magnetic block and the connecting arm are not in contact with each other and keep a certain magnetic attraction distance therebetween.

In summary, compared with the prior art, the above-mentioned embodiment provides a musical instrument lid buffer structure, when the apron 1 overturns downwards, apron 1 and buffering arm 4 butt, and the magnetic path 5 on the buffering arm 4 adsorbs apron 1, make buffering arm 4 and apron 1 contact always, increase the power of being connected between apron 1 and the buffering arm 4, when apron 1 continues to overturn downwards, apron 1 leans on to the center of buffer 3 more and more, the resistance of buffer 3 is bigger, make apron 1 close the lid more and more slowly, realize the buffering effect, avoid hidden danger such as apron 1 tong.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
