[0007] Furthermore, the liquid crystal display is a display module of VP014AKG-01.

[0008] Furthermore, the button switch adopts a 3-position non-locking button switch.

[0009] Furthermore, the vehicle-mounted hand control device also includes a handle, which is fixed on the side of the front box body.

[0040] The handle 5 can be made of a hard material or a flexible material. By providing the handle 5, it is convenient for an operator to grasp the vehicle-mounted hand control device during use.

[0041] Figure 2 It is a schematic diagram of the structure of the vehicle-mounted hand control device. Figure 2 As shown, the integrated circuit board includes a microprocessor, an isolated CAN transceiver, and an RS232 serial port module.

[0042] The isolated CAN transceiver is connected to the microprocessor and also to the aviation plug 3. The aviation plug 3 is connected to the execution structure through a cable, so that the integrated circuit board can communicate with the actuator. The isolated CAN transceiver is used to feed back the status information of the actuator to the microprocessor to realize communication between the vehicle-mounted hand control device and the actuator.

[0043] Preferably, the main control chip of the microprocessor can adopt the SG32F103ZE chip, the working voltage of the chip is 3.3V, and it also has CAN communication, serial communication, SPI and other communication modes, which is easy to use and has wide applicability.

[0044] Preferably, the isolated CAN transceiver can be selected as model Glb1050C, which can provide differential transmission capability and differential reception capability for the bus and CAN controller respectively, and supports a communication rate of up to 1Mbps.

[0045] Considering the compatibility with the LCD, the RS232 serial port module is selected as the communication module between the microprocessor and the LCD. The RS232 serial port module is connected to the microprocessor and the LCD respectively, and is used to send the state information of the actuator received by the microprocessor to the LCD in the form of serial communication.

[0046] The working principle of the vehicle-mounted manual control device controlling the action of the actuator is introduced below.

[0047] The actuator includes a controller, a left actuator and a right actuator. The controller is connected to an isolated CAN transceiver and communicates via a CAN bus. The left actuator is equipped with a motor (referred to as the left motor), and the right actuator is equipped with a motor (referred to as the right motor). Two button switches are used to control the actions of the left and right actuators. Specifically, one of the button switches (hereinafter referred to as the left motor button switch) is used to control the rotation of the left motor, and the other button switch (hereinafter referred to as the right motor button switch) is used to control the rotation of the right motor.

[0048] First, the controller controls the corresponding motor to execute the action by receiving the switch value from the button switch (forward / reverse of the left motor button switch, forward / reverse of the right motor button switch). At the same time, the controller transmits the real-time status information of the motor to the integrated circuit board in the form of CAN bus through the isolated CAN transceiver, converts the CAN communication into RS232 communication through the RS232 serial port module and sends the converted real-time status information of the motor to the LCD display, which displays the real-time status information of the motor.

[0049] Specifically, the operator controls the corresponding actuator actions by operating the two button switches. When the left motor button switch is turned to forward rotation, the controller receives the forward rotation signal and controls the left motor to turn on and the left actuator to turn on. When it is turned to reverse rotation, the controller receives the reverse rotation signal and controls the left motor to turn off and the left actuator to turn off. When the right motor button switch is turned to forward rotation, the controller receives the forward rotation signal and controls the right motor to turn on and the right actuator to turn on. When it is turned to reverse rotation, the controller receives the reverse rotation signal and controls the right motor to turn off and the right actuator to turn on.

[0050] In the process of controlling the corresponding actuator actions through the button switch, the isolated CAN transceiver receives the status information of the left and right actuators and feeds it back to the microprocessor. The microprocessor receives the status information of the actuator and sends it to the LCD display in the form of serial communication. The status information of the left and right actuators is displayed in real time through the LCD display. The status information of the actuator includes motor stroke, actuator switch in place status, corresponding sensor status, etc.

[0051] In the present embodiment, a vehicle-mounted hand control device is provided. By arranging a liquid crystal display on the surface of the front box body, during the process of controlling the action of the actuator by a button switch, the status information of the corresponding actuator can be displayed in real time, and the progress of the motor that controls the action of the actuator can be displayed. When the actuator switch is in place, the status information of the corresponding sensor can be displayed, which is convenient for the operator to judge the working status of the actuator at this time, avoiding reciprocating operations between the vehicle control host and the computer, and at the same time, it can also avoid failure of the limit mechanism.

[0052] Preferably, the accommodating cavity is filled with silicone rubber, and the silicone rubber completely wraps the two button switches.

[0053] In this embodiment, silicone rubber is filled in the accommodating cavity and the two button switches are completely wrapped with silicone rubber, so that the internal electronic components of the button switches can be prevented from being damaged when the vehicle-mounted hand control device falls. At the same time, liquids such as rainwater can be prevented from penetrating into the accommodating cavity from the connection between the front box body and the rear cover (such as the screw connection hole or the connector connection), thereby protecting the internal electronic components of the vehicle-mounted hand control device.

[0054] Preferably, at least one of the front box body and the rear cover is provided with bosses at four corners.

[0055] In this embodiment, by configuring bosses at the four corners of the front box body and / or the rear cover, it is convenient to place the vehicle-mounted hand control device and can also greatly avoid surface wear of the front box body and / or the rear cover.

[0056] Preferably, the surface of the toggle switch is concave.

[0057] In this embodiment, by setting the surface of the button switch to be a concave surface, accidental touch prevention can be achieved.
