Abstract

A remote controller comprises a shifter lever structure, a controller, and a signal emission device. The shifter lever structure comprises a base, a press key movably connected to the base, a shifter lever arranged surrounding the press key and movably connected to the base, and a sensor coupled to the press key and the shifter lever and configured to obtain moving state information about the press key and the shifter lever. A movement mode of the shifter lever is different from a movement mode of the press key. The controller is electrically coupled to the sensor. The signal emission device is electrically coupled to the controller. The controller is configured to receive the moving state information from the sensor and emit a control signal corresponding to the moving state information via the signal emission device.

First claim

What is claimed is:

1. A remote controller comprising:
a shifter lever structure comprising:
a base;
a press key movably connected to the base;
a shifter lever arranged surrounding the press key and movably connected to the base, wherein a movement mode of the shifter lever is different from a movement mode of the press key; and
a sensor coupled to the press key and the shifter lever and configured to obtain moving state information about the press key and the shifter lever;

a controller electrically coupled to the sensor; and
a signal emission device electrically coupled to the controller,
wherein the controller is configured to receive the moving state information from the sensor and emit a control signal corresponding to the moving state information via the signal emission device, and
wherein the press key and the shifter lever are configured to perform at least one of:
the press key sliding relative to the base, or
the shifter lever rotating around the press key, wherein the shifter lever is configured to automatically return to an original position or remain at a current rotation position when the shifter lever is released after rotation.

2. The remote controller according to claim 1 , wherein a sliding direction of the press key approximately coincides with a lengthwise direction of the shifter lever.

3. The remote controller according to claim 1 , wherein the press key comprises a connecting rod inserted in the base and configured to slide in the base along a lengthwise direction of the connecting rod.

4. The remote controller according to claim 3 , wherein:
the connecting rod passes through the shifter lever and is configured to slide relative to the shifter lever, and
the shifter lever is configured to rotate around the connecting rod.

5. The remote controller according to claim 3 , wherein the press key further comprises a button arranged at one end of the connecting rod.

6. The remote controller according to claim 5 , wherein the shifter lever comprises a rotating part and a shifting part connected, to the rotating part, and the shifting part is configured to drive the rotating part to rotate around the connecting rod.

7. The remote controller according to claim 6 , wherein:
a top surface of the rotating part includes an accommodating groove for accommodating the button,
the button is configured to slide in the accommodating groove, and
the connecting rod passes through a bottom part of the accommodating groove.

8. The remote controller according to claim 7 , wherein the shifter lever further comprises a rotary barrel, a first end of the rotary barrel being an opening end fixedly connected to the rotating part, and a second end of the rotary barrel including a through hole for the connecting rod to pass through.

9. The remote controller according to claim 8 , wherein:
the shifter lever structure further comprises a rotation trigger fixedly connected to the second end of the rotary barrel and arranged corresponding to the sensor, and
the sensor is further configured to obtain a rotating state information about the shifter lever by sensing a rotating state of the rotation trigger.

10. The remote controller according to claim 9 , wherein:
the rotation trigger includes a bush mating with the rotary barrel, and
the second end of the rotary barrel is fixed in the hush and is configured to drive the bush to rotate.

11. The remote controller according to claim 9 , wherein the shifter lever structure further comprises a rotation damping mechanism for providing damping during rotation of the shifter lever structure.

12. The remote controller according to claim 11 , wherein:
the rotation damping mechanism comprises:
a plurality of limiting parts arranged on the base and being spaced apart from each other;
an elastic reset member accommodated in an accommodating groove in the rotation trigger; and
a roller ball accommodated in the accommodating groove in the rotation trigger and abutting against the elastic reset member, the roller ball being configured to selectively fit with one of the limiting parts to provide a rotation resistance, or

the rotation damping mechanism comprises:
a plurality of limiting parts spaced apart from each other and arranged on one of the base and the rotation trigger; and
an elastic snapping strip arranged on another one of the base and the rotation trigger and configured to selectively abut against one of the limiting parts to provide the rotation resistance.

13. The remote controller according to claim 9 , wherein:
the shifter lever structure further comprises a circuit board for carrying the sensor, and
the base comprises a mounting barrel for accommodating the rotation trigger and the sensor, the mounting barrel being fixedly connected to the circuit board to form a sealed cavity.

14. The remote controller according to claim 13 , wherein:
an end face at an end of the mounting barrel far away from the circuit board includes an accommodating part, a bottom part of the accommodating part including a penetration hole in communication with an inner cavity of the mounting barrel,
the rotating part is rotatably accommodated in the accommodating part, and
the rotary barrel passes through the penetration hole.

15. The remote controller according to claim 9 , wherein the shifter lever structure further comprises a locking member, an end of the connecting rod far away from the button being connected to the locking member to prevent the connecting rod from falling off the rotation trigger.

16. The remote controller according to claim 3 , wherein the shifter lever structure further comprises a sliding, reset member providing an elastic restoring force to the connecting rod.

17. The remote controller according to claim 1 , wherein the sensor comprises at least one of an angle sensor, an angular displacement sensor, an angular velocity sensor, an angular acceleration sensor, a torque sensor, a distance sensor, a linear displacement sensor, a linear velocity sensor, a linear acceleration sensor, or a pressure sensor.

18. The remote controller according to claim 1 , wherein the press key is configured to automatically reset to an original position or remain at a current sliding position when the press key is released after sliding.
