The body includes a power supply set, a microcontroller, a calling knob, and a wireless communication module. The operational panel includes multiple buttons so that when pressing any one of the multiple buttons, the microcontroller starts the transmission mechanism to actuate the sickbed to lift or descend. The switch is arranged on the body and moves close to or away from the calling knob. When the switch is pushed to abut against the calling knob, the calling knob is maintained on a locking position and does not generate a calling signal. When the switch is pushed to move away from the calling knob, the calling knob is maintained on a starting position and is pressed to conduct the power and to send the calling signal. ## Claims ### Claim 1 A remote control for a sickbed, the sickbed including a holding plate and a transmission mechanism, the remote control being electrically connected with the transmission mechanism to control the holding plate to lift or descend, and the remote control communicating with a remote management platform wirelessly; the remote control comprising: a body; a calling assembly received in the body and including a power supply set, a microcontroller unit, a calling knob, and a wireless communication module which are electrically connected, wherein the microcontroller unit drives and controls the holding plate to lift or descend in a programmable editing manner, the calling knob generates a calling signal, and the calling signal is sent to the remote management platform via the wireless communication module; an operational panel located on the body and including multiple buttons electrically connected with the microcontroller, wherein when pressing any one of the multiple buttons, the microcontroller starts the transmission mechanism to actuate the holding plate to lift or descend; and a switch arranged on the body and moving close to or away from the calling knob, wherein when the switch is pushed to abut against the calling knob, the calling knob is maintained on a locking position and does not generate the calling signal; when the switch is pushed to move away from the calling knob, the calling knob is maintained on a starting position and is pressed to conduct the power and to send the calling signal. ### Claim 2 (depends on 1) The remote control as claimed in claim 1, wherein the body includes a first casing, a second casing connected with the first casing, and an accommodation chamber defined between the first casing and the second casing; the first casing has a first orifice defined on a first end thereof, a second orifice formed beside the first orifice and communicating with the accommodation chamber with the first orifice, wherein the calling knob is received in the first orifice, and the switch is accommodated in the second orifice. ### Claim 3 (depends on 2) The remote control as claimed in claim 2, wherein the first casing of the body further includes a first engagement portion and a second engagement portion which are formed on two sides of the second orifice and located on an inner fringe of the first casing; the switch includes a U-shaped extension fitted on a side of the calling knob, a straight extension located beside the U-shaped extension, a fixing trench defined on a center of the U-shaped extension, a protruded portion extending from the straight extension and out of the second orifice of the body, and a first connection portion and a second connection portion which are located beside the protruded portion. ### Claim 4 (depends on 2) The remote control as claimed in claim 2, wherein the first casing further includes a first defining groove and s second defining groove which are defined on an inner fringe of the first casing, and the second defining groove is away from the first defining groove. ### Claim 5 (depends on 1) The remote control as claimed in claim 1, wherein the power supply set of the calling assembly has a power cable connected with the transmission mechanism. ### Claim 6 (depends on 5) The remote control as claimed in claim 5, wherein the power supply set has a USB connector configured to connect with the power cable parallelly. ### Claim 7 (depends on 1) The remote control as claimed in claim 1, wherein the calling assembly further includes a microphone drive circuit electrically connected with the microcontroller, a speaker drive circuit electrically connected with the microcontroller, a microphone connected with the speaker drive circuit, and a speaker connected with the speaker drive circuit. ### Claim 8 (depends on 1) The remote control as claimed in claim 1, wherein the wireless communication module of the calling assembly sends the calling signal by using Wi-Fi or Bluetooth. ### Claim 9 (depends on 1) The remote control as claimed in claim 1, wherein the calling knob has a display lamp arranged therein so as to emit lights after the calling knob is pressed. ### Claim 10 (depends on 1) The remote control as claimed in claim 1 further comprising a hook arranged on the body.
