For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figures 1 to 3As shown, the pedal device 100 of the present invention includes: a lifting mechanism 2, which includes an electric push rod 2.1, a guide rod 2.2, a bearing support 2.5, an intermediate support beam 2.6, a pedal assembly 3 and a control panel (not shown) connected to the electric push rod 2.1, the intermediate support beam 2.6 is arranged horizontally and the top of the electric push rod 2.1 is connected to the intermediate support beam 2.6, and the electric push rod 2.1 can drive the intermediate support beam 2.6 to do lifting and lowering movements. The two ends of the intermediate support beam 2.6 are respectively connected to the tops of the two bearing supports 2.5, the two bearing supports 2.5 are arranged symmetrically, and the inside of each bearing support 2.5 is penetrated by a guide rod 2.2, each guide rod 2.2 is arranged vertically, and the two bearing supports 2.5 are connected to the pedal assembly 3. The control panel is located on the operating table in the operating room, including a controller and a plurality of control buttons connected to the controller, which can control the start and stop of the electric push rod 2.1 by powering on and off, and can also control the extension and retraction of the electric push rod 2.1 by controlling the forward and reverse rotation of the motor. It should be noted that the electric push rod 2.1 has a built-in worm gear self-locking structure. When the electric push rod 2.1 loses power, it can automatically lock the lifting mechanism 2 to prevent the pedal assembly 3 from abnormally moving under the action of external force.

[0031] According to the present invention, a lifting mechanism 2 is provided, and it includes an electric push rod 2.1, a guide rod 2.2, a bearing support 2.5, an intermediate support beam 2.6, a pedal assembly 3, and a control panel electrically connected to the electric push rod 2.1. Since the top of the electric push rod 2.1 is connected to the intermediate support beam 2.6, the electric push rod 2.1 can drive the intermediate support beam 2.6 to perform lifting and lowering movements. Since the two ends of the intermediate support beam 2.6 are respectively connected to the tops of the two bearing supports 2.5, each bearing support 2.5 is provided with a guide rod 2.2 inside, and the two bearing supports 2.5 are connected to the pedal assembly 3, so that the intermediate support beam 2.6 can drive the bearing support 2.5, and the bearing support 2.5 further drives the pedal assembly 3 to perform lifting and lowering movements, thereby controlling the lifting and lowering of the pedal assembly 3. The lifting mechanism 3 described in the present invention uses the electric push rod 2.1 as a power source, and the driver and passengers can control the extension and retraction of the electric push rod 2.1 through the control buttons on the control panel.

[0032] When the driver or passenger issues an ascending command through the control button on the control panel, the motor of the electric push rod 2.1 rotates forward, the electric push rod 2.1 extends, drives the middle support beam 2.6 to rise, the middle support beam 2.6 drives the bearing support 2.5 to rise, and the bearing support 2.5 drives the pedal assembly 3 to rise. When it rises to a suitable position, a power-off command can be issued through the control button to cut off the power supply to the electric push rod 2.1, and the pedal assembly 3 immediately stops and locks; when the driver or passenger issues a descending command through the control button on the control panel, the motor of the electric push rod 2.1 rotates reversely, the electric push rod 2.1 retracts, drives the middle support beam 2.6 to descend, the middle support beam 2.6 drives the bearing support 2.5 to descend, and the bearing support 2.5 drives the pedal assembly 3 to descend. When it descends to a suitable position, a power-off command can be issued through the control button to cut off the power supply to the electric push rod 2.1, and the pedal assembly 3 immediately stops and locks. Therefore, the lifting and lowering of the pedal assembly 3 can be controlled quickly and conveniently, and the pedal assembly 3 can be stopped at any position, so as to meet the footrest and control requirements of different drivers and improve the driving safety and comfort.

When the electric telescopic rod 2.1.1 is driven by the motor to make an ascending movement, the magnet can move to the ascending magnetic induction switch 2.1.3 and cooperate with the ascending magnetic induction switch 2.1.3 by magnetic induction, and the ascending magnetic induction switch 2.1.3 can then cut off the power supply, and the pedal 3.1 will stop rising, thereby providing an upper dead point for the pedal 3.1. Accordingly, when the electric telescopic rod 2.1.1 is driven by the motor to move downward, the magnet can move to the downward magnetic induction switch and cooperate with the downward magnetic induction switch, and the downward magnetic induction switch can then cut off the power supply, and the pedal 3.1 will stop descending, thereby providing a bottom dead point for the pedal 3.1.
