[0046] Example 1

[0047] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 3 To further explain, the wireless communication module includes a wireless receiver 61 and a wireless transmitter 71. The wireless receiver 61 is installed in the intelligent tailgate central controller 6, and the wireless transmitter 71 is installed in the wireless control operation box 7. The input module includes a button 72. The button 72 includes a two-hand switch 721, a door opening switch 722, a door closing switch 723, an upward switch 724 and a downward switch 725. The two-hand switch 721, the door opening switch 722, the door closing switch 723, the upward switch 724 and the downward switch 725 convert the door opening command into a corresponding radio signal through the internal circuit and send the wireless signal to the wireless receiver 61 through the wireless transmitter 71. After receiving the wireless signal, the wireless receiver 61 transmits it to the main control unit MCU62, which controls the hydraulic tailgate body 1 to open the door after parsing by the main control unit MCU62.

[0048] A door opening command is issued by pressing the two-hand switch 721 and the door opening switch 722, the door closing switch 723, the rising switch 724 and the falling switch 725 of the wireless control operation box 7 at the same time, and the door opening command is converted into a corresponding radio signal through the internal circuit and the signal is sent through the wireless transmitter 71.

[0049] The wireless receiver 61 of the intelligent tailgate central controller 6 detects in real time. When the wireless receiver 61 detects this wireless signal, the wireless receiver 61 in the intelligent tailgate central controller 6 transmits the signal to the main control unit MCU62 for analysis. The main control unit MCU62 analyzes and confirms that the obtained signal is a door opening signal. At this time, the main control unit MCU62 issues a control instruction according to the door opening signal and the real-time signal monitored by the sensor 11 and drives the buzzer on the main control unit MCU62 to issue a door opening prompt sound.

[0050] At the same time, the control driving device 12 controls the hydraulic tailgate body 1 to open the door according to logic

[0051] Example 2

[0052] On the basis of embodiment 1, the following improvements are made to better control the hydraulic tailgate body 1:

[0053] like Figure 4 As shown, the wireless communication module includes a wireless transceiver 5, which is respectively installed in the intelligent tailgate central controller 6 and the wireless control operation box 7, the input module includes a voice control module, the voice control module includes the wireless control operation box MCU73, a voice recognition module 74 and a language output module 75, the output end of the voice recognition module 74 is electrically connected to the signal receiving end of the wireless control operation box MCU73, the control output end of the wireless control operation box MCU73 is electrically connected to the language output module 75, the wireless control operation box MCU73 converts the door opening command into a corresponding radio signal and sends the wireless signal to the wireless transceiver 5 in the intelligent tailgate central controller 6 through the wireless transceiver 5, the wireless transceiver 5 in the intelligent tailgate central controller 6 receives the wireless signal and transmits it to the main control unit MCU62, and the main control unit MCU62 analyzes and controls the hydraulic tailgate body 1 to open the door.

[0054] When the language recognition module detects that an instruction is transmitted to the wireless control operation box MCU73, it recognizes and analyzes the voice content to confirm that it is a user who has been entered into the system and that the instruction content is normal. If there is any abnormality, the wireless control operation box MCU73 will remind and confirm again through the language output module 75 whether it is the user. It must be confirmed that the instruction is issued by the user before the system action can be controlled.

[0055] When the voice command is for the tailgate to rise, the wireless control operation box 7 starts the wireless transceiver 5 to send a wireless signal for the hydraulic tailgate body 1 to rise. The wireless transceiver 5 of the intelligent tailgate central controller 6 detects in real time. When the wireless transceiver 5 captures the wireless signal, the wireless transceiver 5 in the intelligent tailgate central controller 6 transmits the signal to the main control unit MCU62 for analysis, and the main control unit MCU62 obtains the rising signal through analysis. At this time, the main control unit MCU62 sends out the control command according to the rising signal and the real-time signal monitored by the sensor 11, and drives the buzzer on the main control unit to send out the door opening prompt sound, and sends the received signal through the wireless transceiver 5 of the intelligent tailgate central controller 6 to send the received signal feedback, and at the same time controls the driving device 12 to control the hydraulic tailgate body 1 to perform the rising action of the hydraulic tailgate body 1 according to the logic.
