Wherein: 1. the device comprises a palm support, a shield, a proximity switch, a shield adjusting bush, a miniature pressure sensor, a simulation key, a display screen lower arm, a damping hinge, a display screen upper arm, a display screen, a data processing board, a display screen shell and a display screen back plate, wherein the shield adjusting bush is arranged at 4.5.6.6.7.10.11.12.13.13.13.13.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiment is only one embodiment, not all embodiments, of the present invention.
As shown in fig. 1 to 3, the present embodiment provides a piano finger-raising trainer comprising a finger-pressing mechanism, a palm retainer, a display member, and a stand portion. The finger key mechanism comprises five sets of analog keys 6 and a miniature pressure sensor 5, the palm retainer comprises a proximity switch 3, a shield 2 and a shield adjusting bush 4, the display part comprises a display screen 10, a data processing board 11, a display screen shell 12 and a display screen back board 13, and the support part comprises a palm support 1, a display screen lower arm 7 and a display screen upper arm 9.
The simulation key 6 is C-shaped, the upper part is thinner and is a cantilever beam, and the lower part is fixed on the palm support 1 through a fixing hole; the miniature pressure sensor 5 is fixed in the groove at the lower part, and a certain gap is reserved between the miniature pressure sensor and the cantilever beam. After heat treatment, the cantilever beam of the simulation key 6 has certain elasticity and can automatically bounce after being pressed down. When a trainer presses a cantilever of the simulation key 6, the cantilever is contacted with the miniature pressure sensor 5, and the miniature pressure sensor 5 transmits a pressure value signal to the data processing board 11 of the display part; different pressing degrees will display corresponding pressure values. The width of the simulated keys 6 and the distance between the simulated keys are the same as the size of standard piano keys so as to train the hand feeling of the distance between fingers of a trainer.
The proximity switch 3 is clamped on the palm support 1 through two nuts, and the installation height of the proximity switch is adjustable so as to adapt to different palm heights of different trainers. When the palm distance approach switch exceeds a set value, the approach switch 3 sends a signal to the display part, and the display part judges that the hand shape is wrong and gives a prompt. The guard shield 2 erects outside proximity switch 3 through guard shield adjustment bush 4, and the department that corresponds proximity switch 3 on the guard shield 2 is equipped with the opening, and guard shield 2 is used for protecting proximity switch 3, and the height of guard shield 2 is adjusted to accessible guard shield adjustment bush 4 to adapt to different palm heights. The protective cover 2 does not contact the palm during normal training, and the palm can rest on the protective cover 2 when training is stopped.
The data processing board 11 receives signals of the five micro pressure sensors 5 and the proximity switch 3, processes and judges the signals, and sends results to the display screen 10 for real-time display and alarm so as to correct the actions of the trainer. The data processing board 11 may also store training data for a certain period of time. The electrical schematic diagram is shown in fig. 4, and the 5-path A/D sampling module collects analog quantity of the 5-path pressure sensor and transmits the analog quantity to the data processing module; the switching value signal of the proximity switch is also transmitted to the data processing module for processing; and sending the result to a human-computer interface for display after the processing is finished.
The working flow chart of the trainer of the invention is shown in figure 5, and after the device is started, the program is initialized, the current count is cleared, and the device is ready for testing. When the test is started, whether the palm is lifted is judged according to a signal of the proximity switch, and if the palm is not lifted (namely the palm is too close to the proximity switch 3, the proximity switch 3 acts), a hand type error is prompted on a human-computer interface; if the pressure rises, the value of the micro pressure sensor 5 is acquired. If the collected pressure value does not exceed the threshold value (which can be set according to different personnel to ensure that the press exceeding a certain pressure is recorded), the value is not displayed on the human-computer interface; if the pressure value exceeds the threshold value, the effective count of the corresponding finger is increased, and the pressure value grade is displayed (classified into different grades according to the size of the pressure value and set in the factory). And when the training is finished, recording the key pressing times and the key pressing strength grade of the whole training period.
A damping hinge 8 is arranged between the lower arm 7 of the display screen and the upper arm 9 of the display screen, the angle of the display screen 10 can be adjusted and kept according to the sight heights of different trainers, the training condition can be observed conveniently in real time, and the error action can be corrected. After the exercise is completed, the display screen 10 can be folded down and the trainer is converted to palm size for easy storage and carrying, as shown in fig. 6. The palm support 1 is provided with a fixing groove for the simulation key 6, the simulation key 6 is arranged in the groove, and the fixing hole is a waist-shaped hole and has a certain front-back adjusting space to adapt to the finger lengths of different trainers.
Details not described in this specification are within the skill of the art that are well known to those skilled in the art.
The above description is only exemplary of the invention and should not be taken as limiting the invention, as any modification, equivalent replacement, or improvement made without departing from the spirit and principle of the invention should fall within the protection scope of the invention.
