Detailed Description
The following is further detailed by way of specific embodiments:
the first embodiment is as follows:
as shown in fig. 1:
the rotary encoder with the display 7 comprises a main control board 1, a trigger module and the display 7, wherein the main control board 1 is the existing mature technology and is provided with a main control IC (integrated circuit) for identifying and calculating the rotation direction of the trigger module, and the description is omitted; the display 7 is a display device, is arranged on the main control board 1 and is arranged on a cylindrical shell, the trigger module is arranged on the outer side of the circular shell of the display 7 and is rotationally connected with the circular shell; the trigger method module comprises a knob 2, a first microswitch 3, a second microswitch 4 and a gear, wherein the gear is fixedly arranged at the bottom of the knob 2, the knob 2 is rotatably connected with a display 7, the two ends of the gear are respectively provided with the first microswitch 3 and the second microswitch 4, and one microswitch of the first microswitch 3 and the second microswitch 4 is abutted against the top of the gear, so that the microswitch is triggered; the other micro switch is positioned in a space between two teeth of the gear, so that the micro switch is in an un-triggered state; the state is always kept no matter how the knob 2 rotates the two micro switches; when the knob 2 rotates forwards or backwards, the two micro-motions are sequentially switched on and off, the main control IC on the main control board 1 judges that the rotation state of the knob 2 is the forward rotation or the backward rotation according to the characteristics, and the display 7 is driven to display data of corresponding functions, parameters and the like.
When the gear is the external gear 5, the two micro switches are respectively positioned at the two ends of the outer side of the gear.
The second embodiment:
as shown in fig. 2 and 3:
the second embodiment is different from the first embodiment in that the gear of the first embodiment is an external gear 5, the gear of the second embodiment is an internal gear 6, and the first microswitch 3 and the second microswitch 4 of the second embodiment are positioned inside the internal gear 6.
The specific implementation process is as follows:
when using this rotary encoder who takes display 7, at first install this rotary encoder on corresponding equipment, and the circuit has been received, twist knob 2 afterwards, knob 2 drives gear revolve, the tooth of the gear portion triggers one in first micro-gap switch 3 and the second micro-gap switch 4, and another micro-gap switch is then released, first micro-gap switch 3 and second micro-gap switch 4 trigger with by the master control IC on the main control board 1 of the signal passback that releases, master control IC is according to received signal, judge the direction of rotation of knob 2, and then drive display screen shows corresponding function, data such as parameter.
According to the rotary encoder with the display 7, the knob 2 is rotated, the knob 2 drives the gear to rotate, the teeth of the gear sequentially trigger the first microswitch 3 and the second microswitch 4, the first microswitch 3 and the second microswitch transmit signals back to the main control board 1, the main control board 1 recognizes the triggering sequence of the first microswitch 3 and the second microswitch 4, the rotating direction of the knob 2 is further recognized, and the function of the encoder is realized; the rotary encoder is simple in structure, long in service life and low in failure rate.
The foregoing are merely exemplary embodiments of the present invention, and no attempt is made to show structural details, features, or other details of the present invention in the form of a more detailed description, which is presented for the purpose of illustration only, the more detailed description being taken by way of example only, and the more detailed description being presented for the purpose of illustrating the principles of the invention as embodied in the form of a more complete and readily available computer-readable medium.
