Abstract
The utility model provides a device with running -board control motor rotation number, including the bottom plate with set up the running -board on the bottom plate, what the running -board was rotatable fixes on the bottom plate, is connected with the spring between the middle part of running -board and the bottom plate, is provided with apart from the inductor on the terminal bottom plate that corresponds of running -board, links to each other with circuit control module apart from the inductor, circuit control module realizes the control to motor rotation number according to running -board end apart from the inductor conveying and the distance between the bottom plate: when the running -board is trampled to the forward, between the rotational speed of motor and running -board end and the bottom plate apart from the inverse ratio, when backward trampling the running -board, the rotational speed of motor and the distance between running -board end and the bottom plate are directly proportional. The device can realize motor rotation number's linear accurate control.
Description
Technical field
The utility model relates to a kind of motor speed control device of Sewing machines.
Background technology
Sewing machines control rotating speed of the prior art is that the connecting rod by pedal arranges magnetic patch, and the side of magnetic patch arranges magnetic induction sensor, and the magnetic force direction sensed by magnetic induction sensor and magnetic force size are controlled the rotating speed of motor and turn to.The exact linear that this control mode can not realize rotating speed controls.
Utility model content
In order to solve the above problem existed in background technology, the utility model provides a kind of device controlling motor speed with pedal, and this device can realize controlling the exact linear of motor speed.
For achieving the above object, the utility model adopts following technical scheme:
A kind of device controlling motor speed with pedal, comprise base plate and be arranged on the pedal on base plate, it is characterized in that, pedal is rotating to be fixed on base plate, spring is connected with between the middle part of pedal and base plate, the base plate that the end of pedal is corresponding is provided with distance-sensor, distance-sensor is connected with circuit control module, distance between the pedal end that circuit control module transmits according to distance-sensor and base plate realizes the control to motor speed: when forward tramples pedal, the rotating speed of motor and the distance inverse ratio between pedal end and base plate, when oppositely trampling pedal, the rotating speed of motor is directly proportional to the distance between pedal end and base plate.
When just stepping on pedal, circuit control module controls motor and rotates forward.
Anti-when stepping on pedal, circuit control module controls motor reversal.
Described spring is bidirectional spring.
The beneficial effects of the utility model are:
1, the damping of pedal is realized by reactive spring force;
2, by the position of sensor determination pedal;
3, by the pedal position signal that range sensor exports, circuit control module realizes motor speed and the linear accurate control accelerated.
Accompanying drawing explanation
Fig. 1 is the structural representation controlling motor speed device with pedal described in the utility model.
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, the utility model to be further described:
Embodiment 1
As shown in Figure 1, a kind of device controlling motor speed with pedal, comprises base plate 1, pedal assembly 2, spring 3, distance-sensor 4 and circuit control module.Pedal assembly 2 is arranged on base plate 1, and pedal assembly 2 comprises pedal and rotating base, and pedal is rotating to be arranged on rotating base, and rotating base is fixed on base plate 1.Be provided with spring 3 between the middle part of pedal and base plate 1, spring 3 is bidirectional spring, and on the base plate that the end of pedal is corresponding, 1 is provided with distance-sensor 4, and distance-sensor 4 can sense the distance of pedal end-to-end distance from base plate.Trample forward, the elastic force that pedal overcomes spring moves downward, the range information sensed is fed back to circuit control module by distance-sensor 4, and circuit control module controls the rotating forward rotating speed of motor with this.The pedal end-to-end distance of range sensor induction is inversely proportional to from distance and the motor speed of base plate, namely pedal from base plate distance more close to, the rotating speed of motor is higher, thus realizes the linear rotating speed lifting of motor.Anti-when stepping on pedal, overcome the tensile force of spring, circuit control module controls motor reversing, and the pedal end-to-end distance of range sensor induction is directly proportional from the distance of base plate to motor speed, namely pedal from base plate more away from, the rotating speed of motor is higher.
It will be recognized by those skilled in the art; under the prerequisite not departing from protection domain of the present utility model; various amendment, change and combination can be carried out to above-mentioned embodiment, and think that this amendment, change and combination are within the scope of originality thought.
Claims (4)
1. one kind controls the device of motor speed with pedal, comprise base plate and be arranged on the pedal on base plate, it is characterized in that, pedal is rotating to be fixed on base plate, spring is connected with between the middle part of pedal and base plate, the base plate that the end of pedal is corresponding is provided with distance-sensor, distance-sensor is connected with circuit control module, distance between the pedal end that circuit control module transmits according to distance-sensor and base plate realizes the control to motor speed: when forward tramples pedal, the rotating speed of motor and the distance inverse ratio between pedal end and base plate, when oppositely trampling pedal, the rotating speed of motor is directly proportional to the distance between pedal end and base plate.
