The second magnetic component 26 is fixed to the accommodating hole 2531 of the fixing member 253. The fixing member 253 is partially accommodated in the third shaft through hole 2526. The connection end 2126 of the second rod body 212 passes through the first shaft through hole 2506 and the second shaft through hole 2516 sequentially and is finally fixedly connected to the fixing member 253. The second circuit board 27 is fixedly mounted to the two mounting posts 2503 of the connecting bracket 250. In this way, the joystick mechanism 20 is obtained through the assembly.

Referring to FIG. 20, the joystick mechanism 20 is placed in the cavity 120. After passing through a bottom portion of the bottom housing 12, bolts are inserted into and fixed to three mounting posts 2503 of the connecting bracket 250. The second circuit board 27 abuts the bottom portion of the bottom housing 12. The upper housing 11 covers the opening of the cavity 120. The engagement block 112 is correspondingly inserted into the slot 122. The groove 114 correspondingly accommodates the protrusion 124. In this way, the joystick device 100 (for which, reference may also be made to FIG. 4) of this embodiment of the present application is obtained through the assembly.

Referring to FIG. 21, an upward pulling force is applied to the first rod body 210, so that when the pin shaft 214 linearly moves along the first direction (for example, an upward direction in FIG. 21) from an initial position together with the first rod body 210, the first limiting post 2204 abuts one of the abutment portions 2222, the pin shaft 214 drives the other abutment portion 2222 to open along the first direction, and the elastic component 224 is stretched. The first magnetic component 23 is driven by the first rod body 210 to linearly move along the first direction from an initial position. The first magnetic sensor 242 senses a magnetic field change of the first magnetic component 23, to obtain a movement position of the first magnetic component 23 along the first direction. The first circuit board 24 generates a control instruction according to the movement position of the first magnetic component 23 that is obtained by the first magnetic sensor 242. The remote control 200 sends the control instruction to the controlled mobile device, so that the mobile device linearly moves along the first direction.

Referring to FIG. 22, when the pulling force applied to the first rod body 210 disappears, the stretched elastic component 224 restores to an original state, to pull the opening swing block 222 to reset, thereby driving the pin shaft 214, the first rod body 210 and the first magnetic component 23 to reset, so that the first magnetic component 23 moves to the initial position along the second direction.

Referring to FIG. 23, a downward thrust is applied to the first rod body 210, so that when the pin shaft 214 linearly moves along the second direction (for example, a downward direction in FIG. 23) from an initial position together with the first rod body 210, the first limiting post 2204 abuts one of the abutment portions 2222, the pin shaft 214 drives the other abutment portion 2222 to open along the second direction, and the elastic component 224 is stretched. The first magnetic component 23 is driven by the first rod body 210 to linearly move along the second direction from an initial position. The first magnetic sensor 242 senses a magnetic field change of the first magnetic component 23, to obtain a movement position of the first magnetic component 23 along the second direction. The first circuit board 24 generates a control instruction according to the movement position of the first magnetic component 23 that is obtained by the first magnetic sensor 242. The remote control 200 sends the control instruction to the controlled mobile device, so that the mobile device linearly moves along the second direction.

When the thrust applied to the first rod body 210 disappears, the stretched elastic component 224 restores to an original state, to pull the opening swing block 222 to reset, thereby driving the pin shaft 214, the first rod body 210 and the first magnetic component 23 to reset, so that the first magnetic component 23 moves to the initial position along the first direction.

Referring to FIG. 24 and FIG. 25, a twisting force is applied to the first rod body 210, so that the first rod body 210 drives the second rod body 212, the first reset assembly 22 and the first circuit board 24 to rotate along the third rotation direction or the fourth rotation direction. The connection end 2126 drives the rotating member 251 and the fixing member 253 to rotate relative to the connecting bracket 250 and the second circuit board 27 along the third rotation direction or the fourth rotation direction.

When the fixing member 253 rotates relative to the second circuit board 27 along the third rotation direction or the fourth rotation direction, the second magnetic component 26 rotates relative to the second magnetic sensor 272 along the third rotation direction or the fourth rotation direction from an initial position. The second magnetic sensor 272 senses a magnetic field change of the second magnetic component 26, to obtain a rotation amount of the second magnetic component 23 along the third rotation direction or the fourth rotation direction. The second circuit board 27 generates a control instruction according to the rotation amount of the second magnetic component 26 that is obtained by the second magnetic sensor 272. The remote control 200 sends the control instruction to the controlled mobile device, so that the mobile device rotates along the third rotation direction or the fourth rotation direction.

When the rotating member 251 rotates relative to the connecting bracket 250, one of the torsion spring mounting arms 2521 is pushed by one end of the arc-shaped outer side wall 2512 to move along the third rotation direction or the fourth rotation direction toward one end of the other torsion spring mounting arm 2521 and the arc-shaped inner side wall 2506, and one end of the arc-shaped outer side wall 2512 and one end of the arc-shaped inner side wall 2506 respectively press the two torsion spring mounting arms 2521, so that the torsion spring 252 is compressed.

When the twisting force applied to the first rod body 210 disappears, the torsion spring 252 restores to an original shape. The two torsion spring mounting arms 2521 separately pushes one end of the arc-shaped outer side wall 2512 and one end of the arc-shaped inner side wall 2506. The rotating member 251 rotates relative to the connecting bracket 250 along the fourth rotation direction or the third rotation direction, to drive the fixing member 253, the first rod body 210, the second rod body 212, the first reset assembly 22 and the first circuit board 24 to reset along the fourth rotation direction or the third rotation direction, so that the second magnetic component 26 rotates to the initial position along the fourth rotation direction or the third rotation direction.

Referring to FIG. 26, a structure of a joystick device 300 provided in another embodiment of the present application is basically the same as that of the joystick device 100 provided in the foregoing embodiment. A difference lies in that the joystick device 300 adopts a potentiometer 274 instead of the magnetic sensor 272 of the joystick device 100.

The potentiometer 274 is disposed on the circuit board 27. The connection end 2126 is inserted into the potentiometer 274 and in contact with the potentiometer 274.

When the connection end 2126 rotates relative to the potentiometer 274 and the second circuit board 27 along the third rotation direction or the fourth rotation direction, the potentiometer 274 obtains, according to a change in a resistor value or a voltage, a rotation amount of the connection end 2126 along the third rotation direction or the fourth rotation direction. A processor disposed on the circuit board 27 generates a corresponding control instruction. The remote control 200 sends the control instruction to the controlled mobile device, so that the mobile device rotates along the third rotation direction or the fourth rotation direction.

In the joystick devices 100 and 300 in the embodiments of the present invention, the first rod body 210 has movements in only four directions: linearly moving along the first direction and the second direction and rotating along the third rotation direction and the fourth rotation direction. The operations are simple and are easy to remember by a user. Moreover, when the force applied to the first rod body 210 disappears, the first reset assembly 22 or the second reset assembly 25 is capable of making the first rod body 210 reset, thereby further simplifying operations of the joystick device 100.

In some embodiments, the mobile device is a UAV. The remote control 200 is configured to control the UAV. When the first rod body 210 linearly moves along the first direction (for example, the upward direction in FIG. 21), the remote control 200 controls the UAV to ascend. When the first rod body 210 linearly moves along the second direction (for example, the downward direction in FIG. 23), the remote control 200 controls the UAV to descend. When the first rod body 210 rotates along the third rotation direction or the fourth rotation direction, the remote control 200 controls the UAV to rotate leftward or rotate rightward. A moving direction of the first rod body 210 corresponds to a moving direction of the UAV, so that operations of the remote control 200 are intuitive and simple. In addition, the first rod body 210 has movements in only four directions, which is easy to remember by a user. Moreover, when the force applied to the first rod body 210 disappears, the first reset assembly 22 or the second reset assembly 25 is capable of making the first rod body 210 reset, thereby further simplifying operations of the remote control 200.
