[0010] Figure 1 4 is a principle block diagram of the push control device of the mobile DR in the embodiment. DETAILED DESCRIPTION

[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0012] like Figure 1 As shown, a push control device for a mobile DR includes a push-pull handle, a displacement sensor, a main control chip, and a motor. The displacement sensor is set on the push-pull handle to detect the displacement vector of the push-pull handle, and the motor is a wheel-side motor. The displacement sensor is connected to the signal input terminal of the main control chip via an analog-to-digital conversion chip. The analog-to-digital conversion chip is used to convert the analog signal output by the sensor chip into a digital signal. The control signal output terminal of the main control chip is connected to the motor. The main control chip outputs a corresponding control instruction based on the displacement vector detected by the displacement sensor to control the start of the motor to drive the mobile DR to move. The push-pull handle is an important component for the mobile DR operator to control the movement of the mobile DR. The displacement sensor detects its displacement and the main control chip can determine the movement trend of the mobile DR, thereby controlling the start of the motor.

[0013] Specifically, the displacement sensor includes a follow-up strong magnetic plate and a sensor chip arranged on the push-pull handle. The follow-up strong magnetic plate moves with the movement of the push-pull handle. The follow-up strong magnetic plate and the sensor chip are connected. When the follow-up strong magnetic plate moves, the sensor chip detects the corresponding displacement signal and transmits it to the main control chip.

[0014] The push-pull handle is also equipped with an elastic reset element, which is used to reset the push-pull handle and the follower strong magnetic plate. The elastic reset element can be a spring plate. In addition to its reset function, it also helps to fix the push-pull handle and the follower strong magnetic plate. When the push-pull handle is not under force, it can prevent the push-pull handle from being affected by other external factors and prevent the motor from starting accidentally.

[0015] The principle of this utility model is as follows:

[0016] When the entire machine is stationary, the push-pull handle remains stationary, and the reset spring helps secure the handle so that it is not affected by external forces that could cause misalignment. At this point, the follower magnetic plate is relatively stationary, and the sensor chip detects this state and generates an analog signal that is transmitted to the analog-to-digital conversion chip. This signal is then converted into a digital signal and transmitted to the main control chip for analysis. Finally, the main control chip sends a command to the motor to stop.

[0017] When the machine is pushed forward, the push-pull handle moves forward, and the follower strong magnetic plate also moves forward. The sensor chip detects this state and converts the coordinates of the displacement into analog signals, which are continuously transmitted to the analog-to-digital conversion chip. After being converted into digital signals, they are transmitted to the main control chip for analysis and send instructions to control the speed of the motor rotation, thereby controlling the acceleration of the entire machine. At this time, the reset spring plate continuously generates a reverse force due to the push of the handle. When the push stops, this force quickly helps the push-pull handle and the follower strong magnetic plate return to the relative position when the machine was stationary.

[0018] When the whole machine is pulled backward, the principle is the same as when it is pushed forward.

[0019] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
