Aiming at the technical problems reflected in the background technology, this application proposes a force feedback device, which aims to provide users with a better tactile feedback experience, so as to satisfy users' requirements for related equipment (such as various operating handles, toy guns, virtual reality equipment, etc.) , augmented reality equipment, etc., the sensory requirements of the gamepad shown in Figure 1).

The specific structure of the force feedback device proposed by the present application will be described in specific embodiments below:

As shown in Figures 2 to 4, in an embodiment of the force feedback device 100 of the present application, the force feedback device 100 includes:

base 10;

A trigger 20, the trigger 20 is rotatably connected to the base 10, and has an initial position and a sinking position;

A ratchet mechanism 30, the ratchet mechanism 30 includes a ratchet 31, an active pawl 32 and a non-return pawl 33, the ratchet 31 is installed on the base 10 and is located inside the trigger 20; the active pawl 32 is mounted on the inner surface of the trigger 20, and is used to engage with the ratchet 31 as the trigger 20 sinks; the non-return pawl 33 is engaged with the ratchet 31; and

The tightening mechanism 40 , the tightening mechanism 40 is installed on the base 10 and is elastically connected with the non-return pawl 33 , and is used for tightening the non-return pawl 33 on the ratchet 31 .

It can be understood that the base 10 can provide a stable installation platform for the trigger 20, the ratchet mechanism 30, the tightening mechanism 40, etc.; Components independent of the housing of the electronic device 1000 may also be served by the housing of the electronic device 1000 .

The trigger 20 can be a button of various operating handles (such as a game handle, etc.), or a trigger 20 of a toy gun, or a button of a virtual reality device (referred to as a VR device), or an augmented reality device (abbreviated as a VR device). AR device) buttons. The trigger 20 is used to contact with the user's finger to realize force feedback, specifically: the trigger 20 has a fixed end 21 and a moving end 22 connected, and the fixed end 21 of the trigger 20 is connected to the base 10 in rotation, so that the moving end of the trigger 20 22 can be rotated around the fixed end 21 to be displaced, so that it can "bounce" to the highest point to obtain the "initial position", or "sink" to the lowest position to obtain the "sinking position", so that the trigger 20 can move toward the The user's finger feedback force, or cancel the feedback force on the user's finger, and then complete the interaction with the user.

Further, the base 10 is also equipped with a ratchet 31 and a tightening mechanism 40. The ratchet 31 is rotatably connected to the base 10 and can rotate relative to the base 10; The non-return pawl 33 is at intervals in the circumferential direction of the ratchet 31, wherein the non-return pawl 33 is engaged with the ratchet 31, and the active pawl 32 sinks as the trigger 20 moves from the "initial position" to the "sinking position". Engage with the ratchet 31 during the process, specifically: the active pawl 32 is installed on the trigger 20 to follow the movement of the trigger 20 to engage with the ratchet 31 and drive the ratchet 31 to rotate; the non-return pawl 33 is installed on the jacking mechanism 40 Between the ratchet wheel 31, the ratchet wheel 31 is tightened against the ratchet wheel 31 under the action of the tightening mechanism 40 to prevent the ratchet wheel 31 from rotating backwards. At this point, the specific process of force feedback is as follows (see Figure 4 to Figure 8):

When the user's finger presses the trigger 20, the trigger 20 will push the ratchet 31 to rotate through the active pawl 32 during the movement from the "initial position" to the "sinking position"; The gear teeth will push the non-return pawl 33 to move away from the ratchet 31 along the radial direction of the ratchet 31 . During this process, since the clamping mechanism 40 exerts a pre-compression elastic force on the non-return pawl 33, the clamping mechanism 40 will withstand the non-return pawl 33, making it pressed against the ratchet 31; at this time, The pressing force and frictional force between the non-return pawl 33 and the ratchet wheel 31 will be fed back to the trigger 20 through the active pawl 32 to form a feedback force. And, every time the user's finger presses the trigger 20, the active pawl 32 will push the ratchet 31 to rotate "one tooth"; Move quickly along the radial direction of the ratchet 31 in the direction close to the ratchet 31 and return to the original position, so that the ratchet 31 no longer transmits force to the active pawl 32, and the active pawl 32 no longer transmits force to the trigger 20, so that the trigger 20 Produces a quick release of force. And, after the user's finger releases the trigger 20, the trigger 20 can return to the original position, that is, the "initial position" under the action of a return member such as the spring of the trigger 20, thereby waiting for the next press and force feedback output; At the same time, the active pawl 32 also returns to its original position, thereby waiting for the next action and reaction with the ratchet wheel 31 .

That is to say, in the technical solution of this embodiment, a ratchet mechanism 30 is arranged between the trigger 20 and the tightening mechanism 40. Through the ratchet mechanism 30, the pre-compression elastic force of the tightening mechanism 40 can be converted into the force of the trigger 20 during pressing. Force feedback, so that the interaction with the user's fingers can be completed, providing users with a better tactile feedback experience, so as to meet the user's requirements for related equipment (such as various operating handles, toy guns, virtual reality equipment, augmented reality equipment, etc. ) sensory requirements.

It should be noted that, in this embodiment, the base 10 includes a bottom plate 11, a side plate 12 and a connecting portion 13; the bottom plate 11 is arranged horizontally; the side plate 12 is arranged vertically, and is located on one side of the bottom plate 11, and is connected to the bottom plate 11; The connecting portion 13 protrudes from a surface of the side plate 12 facing away from the bottom plate 11 .

Further, as shown in FIGS. 2 to 4 , the connecting portion 13 is horizontally pierced with the trigger shaft 14 , and the inner side of the fixed end 21 of the trigger 20 protrudes from two mounting ears 211 arranged side by side, and each mounting ear 211 has a There is a mounting hole 2111, and two mounting holes 2111 are arranged opposite to each other. The connecting part 13 is inserted between the two mounting ears 211, and the two ends of the trigger shaft 14 are respectively inserted in the two mounting holes 2111. In this way, the fixed end 21 of the trigger 20 is rotatably connected to the connecting portion 13 of the base 10 through the trigger shaft 14 , so that the rotatable connection between the trigger 20 and the base 10 is realized, and the stability and reliability are high. Moreover, the trigger rotating shaft 14 is also sleeved with a trigger torsion spring 15, a support arm of the trigger torsion spring 15 is supported on the base 10, and the other support arm of the trigger torsion spring 15 is supported on the trigger 20, for driving the trigger 20 on the Restore to "initial position" after pressing cancel.

Further, as shown in FIGS. 2 to 4 , the inner side of the trigger 20 is protrudingly provided with a fixed post 23 between the fixed end 21 and the movable end 22 , the fixed post 23 is arranged facing the ratchet 31 , and one end of the active pawl 32 faces the ratchet 31 It is provided that the end of the active pawl 32 away from the ratchet wheel 31 is rotatably connected to the free end of the fixed column 23 through the pawl rotating shaft 34 . It can be understood that the distance between the active pawl 32 and the ratchet wheel 31 can be shortened by the fixed column 23, thereby facilitating the formation of a stable cooperative relationship between the active pawl 32 and the ratchet wheel 31, and facilitating the active pawl 32 and the trigger 20 Obtain a stable force feedback effect, thereby providing users with a better tactile feedback experience. Moreover, the rotation of the active pawl 32 relative to the fixed column 23 is also designed as "one-way rotation", that is, the active pawl 32 cannot rotate relative to the fixed column 23 during the process of "sinking" together with the trigger 20 The purpose is to resist the groove wall of the tooth groove of the ratchet wheel 31, thereby pushing the ratchet wheel 31 to rotate; while the active pawl 32 can rotate relative to the fixed column 23 during the process of "bounce" with the trigger 20, for What is important is to "sweep lightly" the teeth of the ratchet 31 and smoothly transition to the next tooth groove. The specific structure is as follows (referring to Fig. 2 to Fig. 4): one end of the active ratchet 32 away from the ratchet wheel 31 is formed with two opposite installation parts 321, the free end of the fixed post 23 is inserted between the two installation parts 321, and Rotately connected on the two mounting parts 321 by the ratchet shaft 34; and, between the two mounting parts 321, a bearing platform 322 is also provided, and the bearing platform 322 has a table top facing away from the base 10, and the free end of the fixed column 23 faces the base 10. One side abuts against the platform of the carrying platform 322 .

Further, as shown in FIGS. 2 to 4 , a bar-shaped hole 111 is opened on the surface of the bottom plate 11 , one end of the bar-shaped hole 111 is set toward the trigger 20 , and the other end of the bar-shaped hole 111 is set in a direction away from the trigger 20 . The surface of the bottom plate 11 is also protrudingly provided with two fixed plates 16 arranged side by side. The strip hole 111 is transversely separated between the two fixed plates 16. The ratchet 31 is sandwiched between the fixed plates 16 and penetrates through the bottom plate 11 through the strip hole 111. It is arranged and connected to the two fixed plates 16 through the rotation of the ratchet rotating shaft 35 . In this way, not only the rotational connection between the ratchet 31 and the base 10 is realized, which has the advantages of strong stability and high reliability; but also the design of the ratchet 31 passing through the strip hole 111 can also reduce the height of the ratchet 31 relative to the base 10 , so that it can form a stable cooperation with the active pawl 32, thereby improving the stability and reliability of force feedback, and providing users with a better tactile feedback experience.

In addition, it should also be noted that the tightening mechanism 40 can be an elastic member, such as a shrapnel, a spring, a rubber pad, etc., one end of which is fixed on the base 10, and the other end is tightened on the non-return pawl 33, so as to The non-return pawl 33 is tight on the ratchet 31. The tightening mechanism 40 can also be composed of elastic members and other components matched therewith, such as the tightening mechanism 40 described later. Those skilled in the art can make reasonable selections according to the requirements of actual application scenarios, and details will not be repeated here.

As shown in FIGS. 2 to 4 , in an embodiment of the force feedback device 100 of the present application, the clamping mechanism 40 includes:

A limiting block 41, the limiting block 41 is arranged on the side of the non-return pawl 33 facing away from the ratchet 31, and is spaced from the non-return pawl 33 to form an installation space; and

The elastic member 42 is disposed in the installation space, one end of the elastic member 42 abuts against the non-return pawl 33 , and the other end abuts against the limiting block 41 .

It can be understood that the existence of the limit block 41 provides a support basis for the compression of the elastic member 42, so that the end of the elastic member 42 away from the limit block 41 can stably abut against the non-return pawl 33, thereby preventing the return The pawl 33 provides a stable pre-compression elastic force to ensure that a stable force feedback effect can be obtained when the trigger 20 is pressed. Moreover, the design of this embodiment also has the advantages of simple structure, convenient manufacture, and quick assembly.

It should be noted that the non-return pawl 33 and the limit block 41 can be arranged on the same side of the base 10 , for example, the non-return pawl 33 and the limit block 41 are both arranged on the upper surface of the bottom plate 11 of the base 10 in this embodiment . Further, the non-return ratchet 33 can be slidably connected with the base 10, so that the process of moving away from the ratchet 31 and approaching the ratchet 31 can be performed more smoothly. The limiting block 41 can be fixed on the base 10 , or can be set on the base 10 in a manner of sliding connection with the base 10 hereinafter, which will not be repeated here.

As shown in FIGS. 2 to 4 , in an embodiment of the force feedback device 100 of the present application, the limiting block 41 can move toward or away from the non-return pawl 33 to adjust the size of the installation space.

It can be understood that the size of the installation space determines the amount of compression of the elastic member 42 and the size of the pre-compressed elastic force that the tightening mechanism 40 acts on the non-return pawl 33 . In this way, by adjusting the distance between the limit block 41 and the non-return pawl 33, the adjustment of the size of the installation space can be realized, and the adjustment of the pre-compression elastic force of the top tightening mechanism 40 acting on the non-return pawl 33 can be realized, thereby Different pressing forces and frictional forces are generated between the non-return pawl 33 and the ratchet wheel 31, so that the active pawl 32 and the trigger 20 can obtain force feedback effects of different sizes, and realize force feedback effects of different sizes on the user's fingers . In this way, the output of different force value curves can be realized, so that users can obtain a richer tactile experience according to different application scenarios.

It should be noted that, the locking after the movement of the limiting block 41 and the release after locking can be carried out at least in the following manner: (1) a plurality of positioning holes are arranged on the base 10 along the moving direction of the limiting block 41, When the limit block 41 slides to different positioning holes, the limit block 41 is locked at the corresponding positioning hole by a locking member (such as a screw and a nut); (2) along the moving direction of the limit block 41, on the base 10 is configured with a slideway so that the stopper 41 slides in the slideway; a clamping strip is respectively arranged on both side walls of the slideway, and a driving mechanism is configured to drive the two clamping strips to move closer to each other (to clamp and fix the stopper). 41) or away from each other (release limit block 41).

Of course, the locking after the movement of the limiting block 41 and the release after locking can also be carried out in the following manner:

As shown in Figures 2 to 4, in an embodiment of the force feedback device 100 of the present application, the clamping mechanism 40 further includes:

A motor 43, the motor 43 is mounted on the base 10;

Screw mandrel 44, described screw mandrel 44 is extended along the movement direction of described limiting block 41, and transmission is connected with the output shaft of described motor 43, so as to rotate under the drive of described motor 43, described limiting block 41 is sheathed on the threaded rod 44 and is threadedly connected with the threaded rod 44 to move toward or away from the non-return pawl 33 driven by the threaded rod 44 .

It can be understood that such a design can not only realize locking and releasing after the movement of the limit block 41, but also realize "stepless" adjustment, so that users can get richer tactile experience according to different application scenarios , and can also facilitate automatic control, making the adjustment process more convenient and precise.

As shown in Figures 2 to 4, in an embodiment of the force feedback device 100 of the present application, the base 10 is provided with a track 17a, and the track 17a is extended along the moving direction of the limit block 41, and the limit block 41 Bit blocks 41 are provided in said rail 17a to move along said rail 17a.

It can be understood that the design of the track 17a can play an auxiliary role in the sliding of the limiting block 41, making the sliding process of the limiting block 41 more stable, and enabling the process of "changing the preloaded elastic force" of the clamping mechanism 40 to be carried out smoothly. It is more stable, so as to provide users with a better tactile feedback experience. Moreover, the design of the track 17a can also prevent the limit block 41 from rotating together with the screw rod 44, further improving the stability of the limit block 41 during the sliding process, thereby providing users with a better tactile feedback experience.

It should be noted that, in this embodiment, the upper surface of the bottom plate 11 of the base 10 is also protrudingly provided with two limiting bars 17, and the two limiting bars 17 are all extended along the moving direction of the limiting block 41, and the two limiting bars 17 arranged side by side to form the aforementioned track 17a. Moreover, in this embodiment, the bottom wall of the track 17a is also formed with a strip-shaped through hole 112 for accommodating the screw rod 44; the motor 43 is arranged at the end of the screw rod 44 away from the ratchet 31, and is used to drive the screw rod 44 to rotate; at this time, the bottom of the limit block 41 is pierced through the through hole 112, and is sleeved on the screw rod 44, and is threadedly connected with the screw rod 44. In this way, due to the restriction of the two side walls of the through hole 112 and the restriction of the two side walls of the track 17a, when the screw mandrel 44 rotates, the stop block 41 can be driven to move along the length direction of the screw mandrel 44, thereby realizing the Adjustment of the size of the installation space. And, in this embodiment, the inner surface of the limiting bar 17 is also provided with a chute, the chute is arranged along the length direction of the limiting bar 17, and the side of the limiting block 41 facing the chute is protrudingly provided with a slider, and the sliding The block is accommodated in the sliding groove, so as to slide in the sliding groove with the movement of the limiting block 41 . It can be understood that the cooperation of the slider and the chute can improve the stability of the movement of the limit block 41, and make the process of "changing the preload elastic force" of the clamping mechanism 40 more stable, thereby providing users with more Premium tactile feedback experience.

In addition, in order to assist the sliding of the non-return pawl 33, the sliding process of the non-return pawl 33 is more stable, so that the pressing force and friction between the non-return pawl 33 and the ratchet wheel 31 can be generated more stably. force, so as to provide a more stable force feedback output for the trigger 20, and provide users with a better tactile feedback experience. The process and the process of approaching the ratchet 31 can be achieved by sliding in the track 17a. In this way, the sharing of structures can be realized, and the effective unification of enrichment of functions and simplification of structures can be realized.

In addition, the setting of the track 17a can also play a role in standardizing the position of the elastic member 42, helping the compression and elongation process of the elastic member 42 to be carried out more smoothly, so that the non-return pawl 33 and the ratchet 31 can be more stable. The pressing force and the frictional force are stably generated, thereby providing a more stable force feedback output for the trigger 20 and providing a user with a better tactile feedback experience.

As shown in Figures 2 to 4, in an embodiment of the force feedback device 100 of the present application, the force feedback device 100 further includes a potentiometer 50, the potentiometer 50 is installed on the base 10, and is located on the The side of the movement path of the limit block 41;
