When a particular device is described as being coupled to other devices, the particular device may be directly coupled to the other devices without intervening devices or may be directly coupled to the other devices with intervening devices.

In a first aspect, referring to fig. 3 to 4, the present embodiment provides a plastic hardware combination bracket for a musical instrument keyboard, including a metal member 1 and a plastic member 2, where the metal member 1 includes a head key group 11, at least one middle key group 12, and a tail single key 13, which are sequentially arranged on a metal coil material along a first direction, and according to the length of the musical instrument keyboard, metal coil materials with different lengths are cut, where the first direction may be a sequential direction of die stamping on the metal coil material, after the die stamping, the head key group 11, the middle key group 12, and the tail single key 13 are formed on the metal coil material, and preferably, in one stamping process, an octave length corresponding to 12 key positions is formed on the metal coil material.

Wherein, the head key group 11 comprises 12 keys arranged in sequence along a first direction, wherein, the first head key 14 is a half key structure, which is equivalent to 0.5 key, and the rest 11 keys are complete keys;

each middle key group 12 comprises 12 complete key positions which are sequentially arranged along a first direction;

the tail single key 13 is a half-key structure, which is equivalent to a 0.5 key;

the number of the keys in the head key group 11 is the same as that of the keys in the single middle key group 12, the plastic component 2 is coated on the outer surface of the tiled metal component 1, and corresponding splicing parts are respectively formed in the direction of the first head key 14 and the free end of the tail single key 13.

It should be noted that, the stamped metal member 1 is a flat material, if the first head key 14 at the head end of one metal member 1 is bent and spliced with the tail single key 13 at the tail end, a complete key can be spliced, and the total length of the metal member 1 is equivalent to the length of a stamping die in integral multiple and also equivalent to the length of eight degrees in integral multiple, no matter whether a musical instrument keyboard for producing 25 keys, 37 keys, 49 keys, 61 keys and 73 keys is produced, the first head key 14 at the head end is always kept in a half-key structure, the tail single key 13 at the tail end is in a half-enclosure structure, only the eight-degree length in integral multiple needs to be stamped, and the half-key positions before and after stamping do not cause material waste, and the production efficiency is improved.

As shown in fig. 5, compared with the old 25-key metal component, the metal component 1 in the embodiment has the dashed frames at the head and tail ends omitted from the new metal component 1, and has half a key position at the head end and one key position at the tail end, the original old metal component 1 needs 25.5 key positions, the new metal component 1 only needs 24 key positions, and the half key positions at the two ends are made up by plastic injection splicing, so that the metal material is saved, and the zero-waste production is realized.

In this embodiment, the numbers of the key bits in the head key bit group 11 and the middle key bit group 12 are both integer multiples of 12, as shown in the figure, 12 key bits of the head key bit group 11 may be correspondingly equipped with 12 keys, and the first head key bit 14 of the half-key bit structure corresponds to one key; 12 keys of the middle key group 12 can be correspondingly provided with 12 keys; the tail single key 13 of the half key structure corresponds to a key; the total number of the keys is 25, and the requirement of a 25-key musical instrument keyboard is met.

Referring to fig. 6 and 7, as shown in fig. 6, when a new metal member 1 is stamped, the dashed line frame in the figure is the length of stamping, and a new metal member 1 is produced by stamping only twice; as shown in fig. 7, the dashed line box in the figure is the length of stamping, and an old metal component is produced, which needs to be stamped three times, and the metal material stamped out for the third time needs to be cut, resulting in material waste.

As an implementation mode, the combined bracket adopts a mode that a plastic component 2 wraps a metal component 1, in order to improve the structural strength of a first head key position 14 positioned at the head end and a tail single key 13 positioned at the tail end, two splicing parts are formed in the injection molding stage, wherein one splicing part is a head end splicing part 21, the other splicing part is a tail end splicing part 22, the head end splicing part 21 is positioned in the direction of the free end of the first head key position 14, and the head end splicing part 21 and the first head key position 14 of a half-key structure are spliced into a complete key position; the tail end splicing part 22 is positioned in the direction of the free end of the tail single key 13, and the tail end splicing part 22 and the tail single key 13 of the half-key structure are spliced into a complete key position.

It should be noted that, the first head key 14 and the other half key structure of the tail single key 13 are respectively supplemented at the head end and the tail end by injection molding, so that the finally formed combined bracket forms a structure of a complete key position by splicing and fusing plastic and five metallographic phases at both ends, and the plastic splicing length is short, and the single side is only half key position, thereby meeting the strength requirement of use.
