Aiming at the technical problems reflected by the background technology, the invention provides a force feedback device, which aims to provide better tactile feedback experience for a user, so that the sensory requirements of the user on related equipment (such as various operating handles, toy guns, virtual reality equipment, augmented reality equipment and the like, such as a game handle shown in fig. 1) are met.
The specific structure of the force feedback device proposed by the present invention will be described below in specific embodiments:
as shown in fig. 2 to 4, in an embodiment of the force feedback device 100 of the present invention, the force feedback device 100 includes:
a base 10;
the trigger 20 is rotatably connected to the base 10 and has an initial position and a sinking position;
a ratchet mechanism 30, wherein the ratchet mechanism 30 comprises a ratchet wheel 31, a driving pawl 32 and a non-return pawl 33, the ratchet wheel 31 is arranged on the base 10 and is positioned at the inner side of the trigger 20; the active pawl 32 is mounted on the inner side surface of the trigger 20 for engagement with the ratchet wheel 31 as the trigger 20 is depressed; the check pawl 33 is engaged with the ratchet wheel 31; and
and the tightening mechanism 40 is installed on the base 10, is elastically connected with the check pawl 33, and is used for tightening the check pawl 33 on the ratchet wheel 31.
It is understood that the base 10 can provide a stable mounting platform for the trigger 20, the ratchet mechanism 30, the tightening mechanism 40, etc.; the base 10 may be a component separate from the housing of the electronic apparatus 1000, which is provided specifically for mounting the trigger 20, the ratchet mechanism 30, the abutting mechanism 40, and the like, or may be a housing of the electronic apparatus 1000.
The trigger 20 may be a button of various operation handles (for example, a game handle, etc.), a trigger 20 of a toy gun, a button of a virtual reality device (for short, VR device), or a button of an augmented reality device (for short, AR device). The trigger 20 is used for contact with the user's finger to effect force feedback, specifically: the trigger 20 has a fixed end 21 and a movable end 22 connected with each other, the fixed end 21 of the trigger 20 is rotatably connected with the base 10, so that the movable end 22 of the trigger 20 can rotate around the fixed end 21 to displace, and can "bounce" to the highest position to obtain an "initial position", or "sink" to the lowest position to obtain a "sink position", and further the trigger 20 can feed back an acting force to the finger of the user, or cancel the acting force fed back to the finger of the user, thereby completing the interaction with the user.
Furthermore, the base 10 is also provided with a ratchet wheel 31 and a jacking mechanism 40, the ratchet wheel 31 is rotationally connected to the base 10 and can rotate relative to the base 10; the two pawls used in cooperation with the ratchet 31, i.e., the active pawl 32 and the non-return pawl 33, are spaced apart 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 is engaged with the ratchet 31 during the process of falling of the trigger 20 from the "initial position" to the "down position", specifically: an active pawl 32 is mounted on trigger 20 to engage ratchet wheel 31 following movement of trigger 20 and drive rotation of ratchet wheel 31; the check pawl 33 is installed between the tightening mechanism 40 and the ratchet wheel 31 to be tightened against the ratchet wheel 31 by the tightening mechanism 40 to prevent the ratchet wheel 31 from rotating backwards. At this time, the specific process of force feedback is as follows (see fig. 4 to 8):
when the trigger 20 is pressed by the finger of the user, the trigger 20 pushes the ratchet wheel 31 to rotate through the active pawl 32 in the process of moving from the initial position to the sinking position; when the ratchet wheel 31 starts to rotate, the teeth of the ratchet wheel 31 push the check pawl 33 to move away from the ratchet wheel 31 in the radial direction of the ratchet wheel 31. In the process, as the jacking mechanism 40 exerts the function of pre-pressing elasticity on the non-return pawl 33, the jacking mechanism 40 will jack the non-return pawl 33 to press the non-return pawl 31 tightly; at this time, the pressing force and the friction force between the check pawl 33 and the ratchet wheel 31 are fed back to the trigger 20 through the active pawl 32, thereby forming a feedback force. And, each time the trigger 20 is pressed by the user's finger, the active pawl 32 will push the ratchet wheel 31 to rotate "one tooth"; thus, when the teeth contacting the check pawl 33 are shifted to the teeth grooves, the check pawl 33 will move back to the original position in the radial direction of the ratchet wheel 31 in the direction approaching the ratchet wheel 31, so that the force of the ratchet wheel 31 is not transmitted to the active pawl 32, and the force of the active pawl 32 is not transmitted to the trigger 20, thereby causing the trigger 20 to generate the sense of quick force leakage. Also, after the user's finger releases the trigger 20, the trigger 20 may return to its original position, i.e., the "home" position, under the influence of a return member, such as a spring, of the trigger 20, waiting for the next press and force feedback output; at the same time, the active pawl 32 is also returned to the home position, waiting for the next action and reaction with the ratchet wheel 31.
That is, according to the technical solution of this embodiment, the ratchet mechanism 30 is disposed between the trigger 20 and the tightening mechanism 40, and the pre-pressing elastic force of the tightening mechanism 40 can be converted into a force feedback effect on the trigger 20 during the pressing process through the ratchet mechanism 30, so as to complete the interaction with the fingers of the user, provide a better tactile feedback experience for the user, and meet the sensory requirements of the user on the related devices (e.g., various operation handles, toy guns, virtual reality devices, augmented reality devices, etc.).
In the present embodiment, the base 10 includes a bottom plate 11, a side plate 12, and a connecting portion 13; the bottom plate 11 is horizontally arranged; the side plate 12 is vertically arranged, is positioned on one side of the bottom plate 11 and is connected with the bottom plate 11; the connecting portion 13 is protruded from a surface of the side plate 12 facing away from the bottom plate 11.
Further, as shown in fig. 2 to 4, a trigger rotating shaft 14 is horizontally inserted through the connecting portion 13, two mounting lugs 211 are protruded from an inner side of the fixed end 21 of the trigger 20 and arranged side by side, each mounting lug 211 is provided with a mounting hole 2111, the two mounting holes 2111 are arranged oppositely, the connecting portion 13 is inserted between the two mounting lugs 211, and two ends of the trigger rotating shaft 14 are respectively inserted into 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 rotating shaft 14, so that the trigger 20 and the base 10 are rotatably connected, and the trigger has strong stability and high reliability. And, the trigger rotating shaft 14 is further sleeved with a trigger torsion spring 15, one supporting arm of the trigger torsion spring 15 is supported on the base 10, and the other supporting arm of the trigger torsion spring 15 is supported on the trigger 20 for driving the trigger 20 to return to the "original position" after the pressing is cancelled.
Further, as shown in fig. 2 to 4, a fixed column 23 is convexly disposed between the fixed end 21 and the moving end 22 on the inner side of the trigger 20, the fixed column 23 is disposed toward the ratchet 31, one end of the active pawl 32 is disposed toward the ratchet 31, and one end of the active pawl 32 away from the ratchet 31 is rotatably connected to a free end of the fixed column 23 through a pawl rotating shaft 34. It can be understood that the distance between the active pawl 32 and the ratchet wheel 31 can be shortened through the fixing pillar 23, so that a stable matching relationship between the active pawl 32 and the ratchet wheel 31 is facilitated, a stable force feedback effect is facilitated for the active pawl 32 and the trigger 20, and a better tactile feedback experience is provided for a user. Moreover, the rotation of the active pawl 32 relative to the fixed column 23 is also designed to be "unidirectional", that is: the active pawl 32 is unable to rotate relative to the fixed column 23 during the "sinking" with the trigger 20, so as to abut against the walls of the tooth grooves of the ratchet wheel 31, thereby pushing the ratchet wheel 31 to rotate; while active pawl 32 is able to rotate relative to fixed post 23 during the "pop-up" process with trigger 20 in order to "sweep" the teeth of ratchet wheel 31 smoothly into the next tooth slot. The specific structure is as follows (see fig. 2 to 4): two opposite mounting parts 321 are formed at one end of the driving pawl 32, which is far away from the ratchet wheel 31, and the free end of the fixed column 23 is inserted between the two mounting parts 321 and is rotatably connected to the two mounting parts 321 through a pawl rotating shaft 34; moreover, a bearing platform 322 is further disposed between the two mounting portions 321, the bearing platform 322 has a platform surface disposed back to the base 10, and one side of the free end of the fixing column 23 facing the base 10 abuts against the platform surface of the bearing platform 322.
Further, as shown in fig. 2 to 4, a strip-shaped hole 111 is formed in the surface of the bottom plate 11, one end of the strip-shaped hole 111 is disposed toward the trigger 20, and the other end of the strip-shaped hole 111 is disposed in a direction away from the trigger 20. The surface of the bottom plate 11 is further convexly provided with two fixing plates 16 arranged side by side, the strip-shaped hole 111 is transversely arranged between the two fixing plates 16, the ratchet wheel 31 is clamped between the fixing plates 16, penetrates through the bottom plate 11 through the strip-shaped hole 111, and is rotatably connected to the two fixing plates 16 through the ratchet wheel rotating shaft 35. Therefore, the ratchet wheel 31 is rotatably connected with the base 10, and the device has the advantages of strong stability and high reliability; and through the design that the strip-shaped hole 111 is used for the ratchet wheel 31 to pass through, the height of the ratchet wheel 31 relative to the base 10 can be reduced, and the ratchet wheel 31 and the active pawl 32 are convenient to form stable matching, so that the stability and the reliability of the force feedback effect are improved, and a better tactile feedback experience is provided for a user.
Further, it should be noted that the urging mechanism 40 may be a member having elasticity, such as a spring, a rubber pad, etc., and one end thereof is fixed to the base 10 and the other end thereof is urged against the check pawl 33 to urge the check pawl 33 against the ratchet 31. The tightening mechanism 40 may also be formed by a member having elasticity and other components cooperating therewith, such as the tightening mechanism 40 described later. Those skilled in the art can make a reasonable selection according to the requirements of the actual application scenario, and details are not repeated here.
As shown in fig. 2 to 4, in an embodiment of the force feedback device 100 of the present invention, the tightening mechanism 40 includes:
the limiting block 41 is arranged on one side, back to the ratchet wheel 31, of the non-return pawl 33, and the limiting block 41 is spaced from the non-return pawl 33 to form an installation space; and
the elastic piece 42 is arranged in the installation space, one end of the elastic piece 42 abuts against the non-return pawl 33, and the other end of the elastic piece 42 abuts against the limiting block 41.
It can be understood that the existence of the limiting block 41 provides a supporting basis for the compression of the elastic member 42, so that one end of the elastic member 42 departing from the limiting block 41 can stably abut against the non-return pawl 33, and further provides a stable pre-pressing elastic force for the non-return pawl 33, and a stable force feedback effect can be obtained when the trigger 20 is pressed. In addition, the design of the embodiment also has the advantages of simple structure, convenience in manufacturing, rapidness in assembly and the like.
It should be noted that the check pawl 33 and the stopper 41 may be disposed on the same side of the base 10, for example, the check pawl 33 and the stopper 41 are disposed on the upper surface of the bottom plate 11 of the base 10. Further, the check pawl 33 may be slidably coupled with the base 10 to enable a process of moving away from the ratchet wheel 31 and a process of moving closer to the ratchet wheel 31 to be performed more smoothly by a sliding manner. The limiting block 41 may be fixed on the base 10, or may be disposed on the base 10 in a manner of sliding connection with the base 10 later, which is not described herein again.
As shown in fig. 2 to 4, in an embodiment of the force feedback device 100 of the present invention, the limiting block 41 can move toward or away from the check pawl 33 to adjust the size of the installation space.
It is understood that the size of the installation space determines the amount of compression of the elastic member 42 and determines the magnitude of the pre-pressure elastic force of the urging mechanism 40 acting on the check pawl 33. Therefore, the distance between the limiting block 41 and the non-return pawl 33 is adjusted, so that the installation space can be adjusted, the pre-pressing elastic force of the jacking mechanism 40 acting on the non-return pawl 33 is adjusted, different pressing forces and friction forces are generated between the non-return pawl 33 and the ratchet wheel 31, the active pawl 32 and the trigger 20 obtain force feedback effects of different sizes, and force feedback effects of different sizes on fingers of a user are achieved. Therefore, the output of curves with different force values can be realized, and a user can obtain richer touch experience according to different application scenes.
It should be noted that, regarding the locking after the movement of the limiting block 41 and the releasing after the locking, at least the following manners are adopted: (1) a plurality of positioning holes are configured on the base 10 along the moving direction of the limiting block 41, and when the limiting block 41 slides to different positioning holes, the limiting block 41 is locked at the corresponding positioning holes by using locking members (such as screws and nuts); (2) along the moving direction of the limiting block 41, a slideway is configured on the base 10, so that the limiting block 41 slides in the slideway; two clamping strips are respectively arranged on two side walls of the slideway, and a driving mechanism is arranged to drive the two clamping strips to mutually approach (so as to clamp the fixed limiting block 41) or mutually separate (so as to release the limiting block 41).
Of course, the locking after the movement of the stopper 41 and the releasing after the locking can also be performed as follows:
as shown in fig. 2 to 4, in an embodiment of the force feedback device 100 of the present invention, the tightening mechanism 40 further includes:
a motor 43, wherein the motor 43 is arranged on the base 10;
the screw rod 44 extends along the moving direction of the limiting block 41, and is in transmission connection with an output shaft of the motor 43 so as to rotate under the driving of the motor 43, and the limiting block 41 is sleeved on the screw rod 44 and is in threaded connection with the screw rod 44 so as to move towards or away from the non-return pawl 33 under the driving of the screw rod 44.
By the aid of the design, locking and releasing after locking can be achieved after the limiting block 41 moves, stepless adjustment can be achieved, a user can obtain richer touch experience according to different application scenes, and meanwhile automatic control can be achieved conveniently, so that the adjusting process is more convenient and accurate.
As shown in fig. 2 to 4, in an embodiment of the force feedback device 100 of the present invention, the base 10 is provided with a rail 17a, the rail 17a extends along a moving direction of the stopper 41, and the stopper 41 is disposed in the rail 17a to move along the rail 17 a.
Understandably, the design of the track 17a can assist the sliding of the limiting block 41, so that the sliding process of the limiting block 41 is more stable, the process of the pre-pressing elasticity of the jacking mechanism 40 can be more stable, and the user can be provided with better tactile feedback experience. In addition, the design of the track 17a can also play a role in preventing the limiting block 41 from rotating along with the screw rod 44, so that the stability of the sliding process of the limiting block 41 is further improved, and a better tactile feedback experience is provided for a user.
It should be noted that, in this embodiment, two limiting strips 17 are further protruded from the upper surface of the bottom plate 11 of the base 10, the two limiting strips 17 are both extended along the moving direction of the limiting block 41, and the two limiting strips 17 are arranged side by side to form the track 17 a. In addition, in the present embodiment, a strip-shaped through hole 112 is further formed in the bottom wall of the rail 17a, and is used for accommodating the screw rod 44; the motor 43 is arranged at one end of the screw rod 44, which is far away from the ratchet wheel 31, and is used for driving the screw rod 44 to rotate; at this time, the bottom of the limiting block 41 penetrates through the through hole 112, and is sleeved on the screw rod 44 and in threaded connection with the screw rod 44. Thus, due to the restriction of the hole walls on the two sides of the through hole 112 and the restriction of the two side walls of the track 17a, when the screw rod 44 rotates, the limiting block 41 can be driven to move along the length direction of the screw rod 44, thereby realizing the adjustment of the installation space.
