The shell 10 is connected through a detachable structure, and the whole part is made of carbon steel materials, so that the shell 10 is ensured to be light and has corresponding structural strength. Specifically, the housing 10 includes an upper case 11 having a U-shaped cross section in a width direction thereof, a bottom edge 12 provided at both ends of the upper case 11 and extending inward, a bottom plate 13 provided at a bottom of the upper case 11 and connected to the bottom edge 12, and side plates 14 provided at both ends of the upper case 11 and connected to the upper case 11. In the present embodiment, fastening is achieved by a screw structure between the bottom plate 13 and the upper case 11 and both sides of the side plate 14 and the upper case 11.

The upper end face of the housing 10 has an inclined operation face 15 in the width direction, and the MIDI controller in this embodiment is a pedal type, and is placed close to the operation foot in use, and the inclined operation face 15 enables an operator to more clearly see the key position and operate the key position.

The casing 10 is internally provided with a circuit board 20 parallel to the inclined operation surface 15, the circuit board 20 has a PLC control module, and the self-circuit and program control in the circuit board 20 are suitable for a MIDI controller, which is the prior art and will not be described herein.

The upper end inner wall of the upper shell 11 is provided with connecting columns 16 which are fixedly connected with the circuit board 20 at intervals, the connecting columns 16 and the upper shell 11 are integrally injection-molded, screw holes are formed in the connecting columns 16, and the circuit board 20 is fixedly connected with the connecting columns 16 through a thread structure. The structural design enables the upper shell 11 and the circuit board 20 to be connected integrally, replaces the original circuit board 20 to be installed on the lower shell part, improves the installation and positioning effects, and avoids the problem of key position dislocation caused by installation errors of the upper shell 11 and the circuit board 20. In addition, the circuit board 20 may also adopt a built-in power supply and a wireless connection module, or may adopt an interface opened on the side surface of the housing 10 to realize wired power supply and data connection.

The key assembly 30 comprises a plurality of micro switches 21 which are arranged on the circuit board 20 at intervals, wherein the micro switches 21 are commercial parts and are arranged on the circuit board 20, and the purpose of program control is achieved by switching on and off of circuit lines through the micro switches 21.

The nail-stepping key 31 on the upper end surface of the shell 10 is vertically arranged on the inclined operation surface 15, the nail-stepping key 31 and the inclined operation surface 15 are correspondingly arranged at a position close to the connecting column 16, and when the foot part is correspondingly stepped on the nail-stepping key 31, the stress deformation of the upper shell 11 and the circuit board 20 is reduced.

The inclined operation surface 15 of the upper shell 11 is provided with mounting holes 17 which are linearly arranged, the mounting holes 17 are internally provided with radial inward anti-rotation shoulders 18, and the pedal nail mounting is correspondingly arranged in the mounting holes 17 to realize linear positioning mounting.

The nail-stepping button 31 comprises a mounting sleeve 34 embedded on the upper shell 11, and the mounting sleeve 34 is provided with a positioning groove 341 for clamping the anti-rotation shoulder 18, so that the mounting sleeve 34 is prevented from being stressed and twisted in the mounting hole 17. The middle part of the installation sleeve 34 is provided with an annular groove 342 and a step surface, the axial position of the step surface facing the installation sleeve 34 is positioned, a sealing ring 343 which is abutted on the inclined operation surface 15 is sleeved in the annular groove 342, the sealing performance of the upper shell 11 after the hole is opened is improved through the sealing ring 343 of the external surface on the inclined operation surface 15, and the problems that the circuit board 20 is damaged due to water inflow and the like are avoided.

The nail shaft 35 is axially connected to the inner end of the mounting sleeve 34, the output shaft is axially connected to the output shaft, the nail shaft 35 is axially connected to the output shaft, the return spring 36 is abutted to the nail shaft 35 in the mounting sleeve 34, the return spring 36 is abutted to the nail shaft 35, the nail shaft 35 is forced to protrude from the mounting sleeve 34 under the action of no external force, or after the external force is lost, the nail shaft 35 is returned to protrude from the mounting sleeve 34, the elastic sleeve 33 protruding from the end face of the output end 32 is sleeved on the circumferential outer wall of the output end 32, and the elastic sleeve 33 serves as secondary elastic protection of the nail pressing key 31 and the micro switch 21. In this embodiment, the elastic sleeve 33 does not directly contact the micro switch 21, the elastic sleeve 33 contacts the plane around the micro switch 21 earlier than the output end 32, the elastic sleeve 33 is deformed under force and then is flush with the end face of the output end 32, and the output end 32 contacts the micro switch 21 to complete the circuit closing. In the use process, the secondary deformation resistance of the elastic sleeve 33 is used for providing compression buffering, the pressing operation is required to be completed by keeping the stable pressing force of the pressing pin for a long time, the problem of single-key false touch is avoided, and the single-key double-click problem is also reduced due to the obvious paragraph difference between the single-key double-click.

Specifically, the output end 32 has a truncated cone structure with a wide inside and a narrow outside, a limiting groove 321 is arranged at the inner side of the output end 32, one end of the elastic sleeve 33 is embedded into the limiting groove 321, and one end of the elastic sleeve 33, which is close to the outer side of the output end 32, is attached to the outer wall of the output end 32. The limiting groove 321 increases the single-end positioning property of the elastic sleeve 33, and the output end 32 of the truncated cone structure gives the elastic sleeve 33 a good deformation space.

Since the nail-stepping key 31 is linearly mounted on the inclined operation surface 15, the height of the axially moving lowest point of the nail-stepping shaft 35 positioned on the inclined operation surface 15 is greater than the height of the axially moving highest point of the nail-stepping shaft 35 positioned at the adjacent lower end in the width direction of the inclined operation surface 15, namely, when the foot is operated, the simultaneous stepping of the nail-stepping keys 31 at two different heights in the same row is avoided.
