[0051] As shown in Figures 1 and 5, after the control chip U1 of the remote control main control module 1 sends control commands to the LCD color screen module 4, the LCD color screen module 4 controls the LCD color screen to display the corresponding color screen display information through connectors J1 and J2, thereby realizing the display effect of various color screen changes of the remote control.

[0053] As shown in Figures 1 and 7, the voltage regulator chips U2 and U3 of the battery voltage regulator module 6 regulate the output power of the rechargeable battery 7 and output power, which then supplies power to the remote control main control module 1 and the LCD color screen module 4, respectively.

[0054] As shown in Figures 1 and 8, during the operation of the remote control, the MOSFETs Q2 and Q3 of the battery monitoring module 8 are turned on, sending the battery monitoring signal of the rechargeable battery 7 to the main control module 1 of the remote control.

[0055] As shown in Figures 1 and 9-10, during charging, the charging interface module 9 is connected to the charging cable to input an external power source.
