[0024] The pole head assembly is designed with multiple sets of switches with different functions, which can be programmed to perform different functions to adapt to different task requirements.
[0025] This utility model patent contains 24 components, as shown in the figure below.
[0026] 1) The outer frame is made of aluminum protective plate, which can play a role in moisture protection, dust protection and electromagnetic shielding.
[0027] 2) The spring cylinder adopts a two-way pressure spring, which ensures that the rod head exerts pressure on the spring in all directions, thereby ensuring that the force is consistent in all directions. Moreover, the durability and reliability of the spring under compression is much greater than that under tension. This design can greatly increase the service life of the device.
[0028] 3) The rocker arm assembly can transmit the horizontal movement of the sensor to the pitch and roll movement of the control stick;
[0029] 4) Bearings are steering components in motion;
[0030] 5) The connecting rod is a component that transmits motion;
[0031] 6) The rocker arm is a component that provides proportional transmission and steering for motion;
[0032] 7) Rotary dampers are used to provide damping in the pitch and roll directions;
[0033] 8) A linear sensor is a component for measuring stroke;
[0034] 9) The handle base is used to connect the handle and the bearing;
[0035] 10) The pitch assembly includes components such as springs, sensors, and dampers in the pitch direction;
[0036] 11) The roll assembly includes components such as spring cylinders, sensors, and dampers in the roll direction;
[0037] 12) The control stick includes the stick head and the stick head switch;
[0038] 13) The limit seat is used to adjust the maximum travel;
[0039] 1) Pushing the control stick forward causes the handle base to move the pitch assembly bearing in the opposite direction. The sensor measures the distance moved and sends the data back to the acquisition system. During the movement, a compression of the longitudinal control force spring assembly provides a force proportional to the distance moved.
[0040] 2) Pulling the control stick backward causes the handle base to move the pitch assembly bearing in the opposite direction. The sensor measures the movement distance and sends the data back to the acquisition system. During the movement, a compression of the longitudinal control force spring assembly provides a force proportional to the movement distance.
[0041] 3) Pressing the control stick to the left causes the handle base to move the roll assembly bearing in the opposite direction. The sensor measures the distance moved and sends the data back to the acquisition system. During the movement, the compression of the lateral control force spring assembly provides a force proportional to the distance moved.
[0042] 4) Pressing the control stick to the right causes the handle base to move the roll assembly bearing in the opposite direction. The sensor measures the distance moved and sends the data back to the acquisition system. During the movement, a compression spring assembly provides a force proportional to the distance moved.
[0043] 5) When the control stick is pressed diagonally, the handle base simultaneously drives the pitch and roll assembly bearings to move in the opposite direction. Sensors measure the movement distance and feed it back to the data acquisition system. During the movement, the longitudinal and lateral control force spring assemblies are compressed to provide a force proportional to the movement distance. The two directional assemblies move independently during this movement without affecting each other.
