[0036] The present application provides a trigger device 1, which can be used in gamepad, VR handle or other human-computer interaction equipment. In combination with Figure 1 and Figure 2 As shown, the trigger device 1 of the embodiment includes a mounting seat 30, a trigger button 20 and a detection assembly 40.

Specifically, the magnetic inductor 42 of the embodiment is a Hall sensor, which has good linearity and can obtain high-precision detection results.

[0037] According to the trigger device 1 of the present application, by sleeving the annular magnet 41 on the rotating shaft 10 and synchronously rotating with the trigger button 20, fixing the magnetic sensor 42 on the mounting seat 30 and oppositely arranging the annular magnet 41, when the trigger button 20 rotates, the magnetic field direction of the annular magnet 41 changes, the magnetic sensor 42 detects the change of the magnetic field direction to determine the rotation angle of the trigger button 20, thereby real-time detecting and feeding back the position of the trigger button 20, and further improving the accuracy of the position feedback of the trigger button 20.

[0038] Specifically, as shown in Figure 1 and Figure 2 , the rotating shaft 10 of the present embodiment is rotatably connected to the mounting seat 30, the mounting seat 30 is provided with two bearings coaxially and spaced apart, the two ends of the rotating shaft 10 are respectively inserted into the two bearings and can rotate, thereby realizing the rotational connection between the rotating shaft 10 and the mounting seat 30. The trigger button 20 includes a trigger body 21, the trigger body 21 is provided with at least two fixed ears 23 spaced apart, specifically, the number of fixed ears 23 of the present embodiment is two, and the fixed ears 23 are provided with through holes. The rotating shaft 10 passes through the through holes on the fixed ears 23 and is fixedly connected with the trigger button 20, and the specific connection mode can be gluing, clamping or welding, thereby realizing the common rotation of the trigger button 20 and the rotating shaft 10 around the axial direction of the rotating shaft 10.

[0039] Further, the rotating shaft 10 of the present embodiment is also provided with assembly ears 22, the number of assembly ears 22 is also two and is respectively arranged on the two sides of the two fixed ears 23, the annular magnet 41 can be sleeved on the rotating shaft 10 and connected with the assembly ears 22, and the specific connection mode can be gluing or clamping. The mounting seat 30 is provided with a magnetic sensor 42, and the specific connection mode can be gluing or clamping, and the annular magnet 41 and the magnetic sensor 42 are oppositely arranged to ensure that the magnetic sensor 42 can quickly and effectively detect the change of the magnetic field of the annular magnet 41. By fixing the annular magnet 41 on the rotating shaft 10 and synchronously rotating with the rotating shaft 10, the accuracy of detecting the rotation angle of the trigger button 20 can be further ensured. In other embodiments of the present application, the annular magnet 41 can also be fixed on the side of the trigger button 20 facing the magnetic sensor 42.

[0040] In other embodiments of the present application, the rotating shaft 10 can be fixedly connected to the mounting seat, such as gluing, welding or clamping, so that the rotating shaft 10 cannot rotate around its axial direction. The trigger button 20 is rotatably connected to the rotating shaft 10, specifically, a bearing can be arranged in the through hole of the fixed ear 23 of the trigger button 20, the trigger button 20 is matched with the rotating shaft 10 through the bearing, and is sleeved on the outside of the rotating shaft 10 in a rotatable manner around the axial direction of the rotating shaft 10, and the annular magnet 41 is fixed on the assembly ear 22 of the trigger button 20 and rotates with the trigger button 20.

[0041] In the above embodiments, the magnetic sensor 42 is fixed on the mounting seat 30, and the annular magnet 41 is fixed on the trigger button 20 or the rotating shaft 10. In other embodiments of the present application, the annular magnet 41 can also be fixed on the mounting seat 30, and the magnetic sensor 42 is arranged on the trigger button 20 or the rotating shaft 10 and rotates together with the trigger button 20. Similarly, the change of the magnetic field direction of the annular magnet 41 can be detected by the magnetic sensor 42, so as to determine the rotation angle of the trigger button 20, and then the position of the trigger button 20 can be detected and fed back in real time, and the accuracy of the position feedback of the trigger button 20 is improved.

[0042] Further, the annular magnet 41 of the present embodiment further comprises a cutaway portion 411, and the trigger body 21 or the assembly lug 22 is provided with a limiting portion (not shown in the figure) matched with the cutaway portion 411. Through the limiting portion, the annular magnet 41 can be positioned and installed, and the annular magnet 41 is driven to rotate together with the trigger button 20. Specifically, the annular magnet 41 of the present embodiment is magnetized along one diameter direction, that is, one side of the radial direction of the annular magnet 41 is S pole, and the other side of the radial direction is N pole. At the same time, in order to facilitate the monitoring of the rotation direction of the trigger button 20, the magnetization direction of the annular magnet 41 of the present embodiment is parallel to the plane where the cutaway portion 411 is located, so as to facilitate the identification of the magnetic field direction of the installed annular magnet 41.

[0043] Further, as shown in Figure 1 and Figure 2 , the trigger body 21 of the present embodiment comprises a small end 211 and a large end 212, wherein the small end 211 is arranged close to the magnetic sensor 42, and the large end 212 is arranged away from the magnetic sensor 42. The assembly lug 22 and the fixed lug 23 are arranged on the side of the small end 211 facing the magnetic sensor 42, and the rotating shaft 10 passes through the through hole of the assembly lug 22 and the fixed lug 23 and is arranged on one side of the small end 211. By pressing the large end 212, the trigger button 20 rotates around the side where the small end 211 is located, so as to facilitate the pressing of the trigger button 20. At the same time, the annular magnet 41 arranged on the rotating shaft 10 is arranged closer to the magnetic sensor 42, the change of the magnetic field when the annular magnet 41 rotates is more obvious, and the detection result of the magnetic sensor 42 is more accurate.

[0044] Further, as shown in Figures 3 to 5 , the annular magnet 41 of the present embodiment is sleeved on the outside of the rotating shaft 10, and in the initial position of the trigger button 20, the S pole of the annular magnet 41 is arranged close to the magnetic sensor 42, and the N pole of the annular magnet 41 is arranged away from the magnetic sensor 42. When the trigger button 20 is pressed under the action of the pressing force, the S pole of the annular magnet 41 is arranged away from the magnetic sensor 42, and the N pole of the annular magnet 41 is arranged close to the magnetic sensor 42. Figure 3When the trigger button 20 rotates in the counterclockwise direction in the figure, the S pole of the annular magnet 41 gradually moves away from the magnetic sensor 42, and the N pole of the annular magnet 41 gradually moves close to the magnetic sensor 42. When the distance between the S pole and the N pole and the magnetic sensor 42 is equal, the induced current of the magnetic sensor 42 is zero at this time, and the rotation position of the trigger button 20 at this time is defined as the middle position. Further rotation of the trigger button 20 causes the N pole to be arranged close to the magnetic sensor 42 and the S pole to be arranged away from the magnetic sensor 42. At this time, the output current of the magnetic sensor 42 is opposite to the output current at the initial position, and finally the magnitude of the reversed output current is the same as the magnitude of the output current at the initial position. The rotation of the trigger button 20 is stopped, and the rotation position of the trigger button 20 at this time is defined as the end position. In this way, the rotation angle and position of the trigger button 20 are accurately determined according to the magnitude and direction of the output current of the magnetic sensor 42 after the change of the magnetic field.

[0045] Further, the trigger device 1 of the embodiment further includes a torsion spring (not shown in the figure) sleeved on the rotating shaft 10. Two force arms of the torsion spring are respectively abutted or fixed to the mounting seat 30 and the trigger button 20, and are used to restore the trigger button 20 to the original position after being pressed. When the trigger button 20 is pressed, the torsion spring is compressed and has elastic force. When the pressing force of the trigger button 20 disappears or decreases, the trigger button 20 is restored to the original position under the elastic force of the torsion spring.

[0046] The application further provides a human-computer interaction device having the trigger device 1 of any of the above embodiments.

[0047] The human-computer interaction device of the application has the trigger device 1 of any of the above embodiments, and has the same technical effects as the trigger device 1 of the application, which will not be described here.

[0048] The above is only a preferred specific embodiment of the application, but the protection scope of the application is not limited to this. Any changes or replacements within the technical range disclosed in the application can be easily thought of by those skilled in the art, and should be covered in the protection scope of the application.
