In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many different forms other than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention, and it is therefore not to be limited to the specific embodiments disclosed below.
Referring to fig. 1, 2, 3 and 4, an embodiment of the present invention provides the rocker device. The rocker device includes a rocker including a main lever 210, a touch pad 220, and a main control circuit 230. The touch pad 220 is disposed on the surface of the main rod 210, and is used for generating a trigger signal when a capacitance difference is detected. The main control circuit 230 is electrically connected to the touch pad 220, and configured to receive the trigger signal and release the locking state of the joystick according to the trigger signal.
It is understood that the joystick device generates two-stage signals during the manipulation, and when the finger of the medical staff touches the touch pad 220, the parasitic capacitance of the human body is coupled to the static capacitance on the touch pad 220 (i.e., the capacitance existing between the touch pad 220 and the ground when no finger is touched), the capacitance on the touch pad 220 changes, and generates a capacitance difference compared with the previous capacitance, thereby generating a minute current, i.e., the trigger signal, is now sent to the master control circuit 230 as a first stage pass signal, so that the main control circuit 230 releases the locking state of the rocker according to the trigger signal, and further, and according to the operation of the rocker, an operation signal generated by a potentiometer or a Hall chip in the rocker device is used as a second-stage transmission signal and is sent to the medical examination bed, so that the medical examination bed can move in multiple dimensions according to the operation signal. In addition, when the palm leaves the rocker, the trigger signal disappears, and the main control circuit locks the rocker. In this embodiment, by adding the touch pad 220, the touch pad 220 generates a trigger signal when detecting the capacitance difference, so that the main control circuit 230 releases the locking state of the rocker according to the trigger signal, and then the rocker can be operated to limit other objects except a human body from triggering the rocker device, thereby avoiding potential safety hazards caused by mistaken touch. In addition, medical personnel do not need to worry about misoperation caused by not touching the rocker, and the use experience of the user is improved.
