Referring to Fig. 1 to Fig. 7 of attached drawing, the device with pedal of the electric keyboard instrument of embodiment according to the present utility model will be
Be elucidated in following description, wherein the extension of bar portion solves the density issue of path channels, pedal rotational angle compared with
The relatively narrow problem of audio range caused by small, realizes and obtains biggish potentiometer rotational angle with lesser pedal rotational angle,
To obtain bigger audio range.
As shown in attached drawing 1 to attached drawing 3, the device with pedal of the present embodiment is in first beginning and end stress, including pedal body
10 and potentiometer 20, the potentiometer 20 is equipped with the bar portion 21 for driving the potentiometer 20 to rotate, and sets in the bar portion 21
There are the extension 22 of the front end side extension towards the pedal body 10,10 bottom of pedal body and the extension 22
Corresponding position is equipped with transfer part 11；Wherein
The upper surface of the extension 22 and the lower surface of the transfer part 11 offset, and the upper surface of the extension 22
For cambered surface 24, the bottom brought into linear contact with the transfer part 11 is remained in relative movement thereof.
More specifically, the lower surface of transfer part 11 and 24 starting point of cambered surface of the upper surface of extension 22 offset, described
The upper surface of extension 22 has 24 vertex of cambered surface and the first position 25 and the second position 26 at 24 both ends of cambered surface, the
One position 25 is 24 starting point of cambered surface of the upper surface of extension 22, and the second position 26 is the upper surface of extension 22
24 clearing end of cambered surface, the transfer part 11 during the pushing of the pedal body 10 with the contact position of the extension 22
From the first position 25 gradually to the smooth movement of the second position 26, in moving process, transfer part 11 always with extension 22
Line contact is kept, extension 22 conducts power to bar portion 21, and then potentiometer 20 is driven to rotate, and potentiometer 20 is mounted in circuit base
On plate, potentiometer 20 is set to rotate respective angles by the pushing angle of pedal, to input corresponding voltage value via connection electricity
Cable exports electron keyboard instrument, so that the musical sound for exporting electric keyboard instrument brings the audio of corresponding pedal depression amount.
And the bar portion 21 of the present embodiment is used, since extension 22 is arranged, and extension 22 is to the front end of pedal body 10
Portion side extends, and makes pedal body 10 during the depression process, first presses extension 22, rotates down extension 22, band electrokinetic potential
Device 20 rotates, and the angle that extension 22 rotates is greater than the rotational angle of pedal body 10, from realizing with lesser pedal angle of rotation
Degree obtains biggish 20 rotational angle of potentiometer, to obtain bigger audio range；In this way using as introduced in background technique
Existing patent 21 structure of bar portion, be equivalent to the transfer part 11 of pedal body 10 and directly relatively moved with the second position 26,
The rotating torque very little of bar portion 21, the power acted on potentiometer 20 will be very big, and feedback to the strength on pedal is uneven
, potentiometer 20 is more easy to damage.The upper surface that the extension 22 of the present embodiment is contacted with transfer part 11 is cambered surface 24, and from first
The 25 to the second position of position 26 is rounding off, and the curvature of the upper surface of the lower surface and extension 22 of transfer part 11 is not
Together, so that it is line contact always that the two is in opposite sliding process, the collision in face and face in motion process is eliminated, collision is eliminated
Noise；It is maximized as far as possible using contact point stress torque of the extension 22 between rotation process and transfer part 11 simultaneously, thus
Potentiometer 20 is reduced by axial impact force, avoids that potentiometer 20 is caused to damage, improves the service life of potentiometer 20.Such as
Shown in the drawings, the pedal body 10 of the present embodiment declines 10 °, and extension 22 and potentiometer 20 rotate 45 °.
At the same time, the amount of spin of pedal body 10 corresponds to the rotation input quantity of potentiometer 20 also by 11 following table of transfer part
The shape in face determines, by suitably change 11 lower surface of transfer part shape can any 10 input quantity of setting pedal body with it is right
The relationship of the voltage value of electric keyboard instrument output, in the present embodiment, in order to realize that lesser amount of spin corresponds to biggish output
Voltage range, the bottom surface of the transfer part 11 form to the rear end portion side of the pedal body 10 and decline inclined inclined surface 12,
The inclined surface 12 is contacted with the upper surface line of the extension always.
As shown in Fig. 5, structural schematic diagram when the second position 26 is located at for the transfer part 11 of the present embodiment, works as transmitting
When portion 11 is moved to the second position 26 with respect to extension 22, between the rear end and the bar portion 21 of 22 upper surface of extension
Equipped with drop notch, second position 26 is the highest point of the rear end of 22 upper surface of extension, if pedal body 10
It needs to continue to push, then transfer part 11 will continue to be contacted with the second position 26 until pedal body 10 presses to the limit.
Bar portion 21 needs that potentiometer 20 is driven to rotate together, therefore turns between bar portion 21 and potentiometer 20 there can be no opposite
Dynamic, as shown in Fig. 7, bar portion 21 includes sleeve part 23 and extension 22, and sleeve part 23 is set in the transmission shaft 201 of potentiometer 20
On, it is rotated synchronously with transmission shaft 201, detent component 30, the detent group is equipped between the bar portion 21 and the transmission shaft 201
Part 30 includes fixture block 32 and card slot 31 compatible with the fixture block 32, the setting of one of the fixture block 32 and the card slot 31
In the bar portion 21, in the transmission shaft 201, the fixture block 32 is clamped described to connect with the card slot 31 for another one setting
Bar portion 21 and the transmission shaft 201.More specifically, as shown in the embodiment of attached drawing, the side of the transmission shaft 201 is equipped with
Notch face 33, the fixture block 32 are provided projectingly on the notch face 33；On the inner wall of the sleeve part 23 of the bar portion 21 with
The corresponding cooperation plane 34 in the notch face 33, the card slot 31 are correspondingly arranged in the cooperation plane 34, are worth noting
, the position of card slot 31 and fixture block 32 is interchangeable, is not limited by embodiment shown in attached drawing, card slot 31 may be provided at transmission
Corresponding on axis 201, fixture block 32 is arranged on 21 inner wall of bar portion, and fixture block 32 and card slot 31 are clamped to drive potentiometer 20 with bar
Portion 21 rotates.The purpose that notch face 33 is arranged and cooperates plane 34 is, makes bar portion 21 and the contact area of transmission shaft 201 more
Greatly, strength transmitting is more stable, and is less likely to be damaged junction.
In order to realize the reset of potentiometer 20, it is arranged with return mechanism in the bar portion 21, more specifically, sleeve part 23
Outer sheath be equipped with torsional spring 27, the mounting portion 28 of one end and 22 side of extension of torsional spring 27 offsets, the other end and potentiometer 20
