In view of the above technical problems, the present invention provides a trigger button device 100, which is intended to provide a better tactile feedback experience for a user, so as to meet the sensory requirements of the user on related devices (e.g., various operation handles, virtual reality devices, augmented reality devices, etc.).

The specific structure of the trigger button device 100 of the present invention will be described below in the specific embodiment:

as shown in fig. 1, 2, 6 and 7, in an embodiment of the trigger button device 100 of the present invention, the trigger button device 100 includes:

a base 10;

the key 20 is provided with a fixed end 21 and a movable end 23 which are connected, and the fixed end 21 is rotatably connected to the base 10, so that the key 20 has a bounce position and a sinking position;

one end of the two-bar linkage 30 is rotatably connected to the moving end 23, and the other end of the two-bar linkage 30 is rotatably connected to the base 10, the two-bar linkage 30 has an expanded state and a collapsed state, the two-bar linkage 30 drives the key 20 to be located at the bounce position when in the expanded state, and the two-bar linkage 30 drives the key 20 to be located at the sink position when in the collapsed state; and

and the driving component 40 is arranged on the base 10 and used for driving the two-link mechanism 30 to be converted from the folded state to the unfolded state.

It can be understood that the base 10 can provide a stable mounting platform for the keys 20, the two-bar linkage 30, the driving assembly 40, etc.; the base 10 may be a separate component from the housing of the electronic device, which is specially provided for mounting the key 20, the two-bar linkage 30, the driving unit 40, and the like, or may be a housing of the electronic device.

The keys 20 may be keys of various operation handles (e.g., game handles), keys of virtual reality devices (VR devices for short), or keys of augmented reality devices (AR devices for short); the keys 20 are for contact with the user's fingers: the fixed end 21 of the key 20 is rotatably connected with the base 10, so that the movable end 23 of the key 20 can rotate around the fixed end 21 to displace, and can bounce to the highest position to obtain a bounce position, or sink to the lowest position to obtain a sink position, so that the key 20 can feed back an acting force to the finger of a user, or cancel the acting force fed back to the finger of the user, and further complete the interaction with the user.

A two-bar linkage 30 is further connected between the moving end 23 of the key 20 and the base 10, that is, one end of the two-bar linkage 30 is rotatably connected with the moving end 23 of the key 20, and the other end of the two-bar linkage 30 is rotatably connected with the base 10. The method specifically comprises the following steps: the two-link mechanism 30 comprises a first link 31 and a second link 33, wherein one end of the first link 31 is hinged to one end of the second link 33, one end of the first link 31, which is away from the second link 33, is hinged to the moving end 23 of the key 20, and one end of the second link 33, which is away from the first link 31, is hinged to the base 10; at this time, the base 10, the key 20, the first link 31, and the second link 33 together constitute a "four-link mechanism". In addition, in the present embodiment, when the two-bar linkage 30 is in the unfolded state, the first link 31 and the second link 33 are arranged at an obtuse angle (as shown in fig. 6), and correspondingly, the key 20 is located at the "pop-up position"; when the two link mechanisms 30 are in the folded state, the first link 31 and the second link 33 are disposed at an acute angle (as shown in fig. 7), and accordingly, the key 20 is located at a "down position". It should be noted that the expanded state and the collapsed state of the two-link mechanism 30 are relative to each other, that is, when the two-link mechanism 30 is converted from the expanded state to the collapsed state, the included angle between the first link 31 and the second link 33 is decreasing and tends to be collapsed; on the contrary, when the two-link mechanism 30 is converted from the folded state to the unfolded state, the included angle between the first link 31 and the second link 33 is enlarged and tends to be unfolded; the actual size of the included angle between the first link 31 and the second link 33 can be set by those skilled in the art according to the specific application, and is not limited.

Further, a driving assembly 40 is disposed on the base 10, and the driving assembly 40 can drive the two-bar linkage 30 to change from the folded state to the unfolded state. It will be appreciated that when the two-bar linkage 30 is driven by the driving assembly 40 and has a tendency to transition from the folded state to the unfolded state, the button 20 accordingly has a tendency to move from the "down position" to the "up position"; at this time, when the user's finger presses the key 20, the key 20 feeds back an acting force to the user's finger, thereby realizing a force feedback function. When the driving component 40 no longer drives the two-bar linkage 30, the trend of the two-bar linkage 30 from the folded state to the unfolded state is cancelled, and the trend of the key 20 from the 'sinking position' to the 'bouncing position' is cancelled; at this point, the force of the feedback on the user's finger is removed and the key 20 can be moved from the "pop-up" position to the "down" position by the user's depression. Therefore, the interaction with the fingers of the user can be completed, more realistic tactile feedback experience is provided for the user, and the sensory requirements of the user on related equipment (such as various operation handles, virtual reality equipment, augmented reality equipment and the like) are finally met.

It should be noted that the driving assembly 40 can be a swinging rod 41 and related structures (described later); the linear driving assembly 40 (e.g., the linear motor 46, the air cylinder, the electric cylinder, the screw rod transmission mechanism, etc.) may also be used to push or pull the two-link mechanism 30 by using the sliding end of the linear driving assembly 40 that moves linearly, and drive the two-link mechanism to change from the folded state to the unfolded state; for example, an end of the second link 33 of the two-link mechanism 30, which is away from the first link 31, is further sleeved on the output shaft of the motor 46, so that the second link 33 is driven to swing by the rotation of the output shaft of the motor 46, thereby driving the two-link mechanism 30 to convert from the folded state to the unfolded state.

Referring to fig. 3, in an embodiment of the trigger button device 100 of the present invention, two opposite connection plates 231 are disposed on a side of the moving end 23 facing the two link mechanisms 30, each connection plate 231 is disposed with a connection hole 233, and the two connection holes 233 are disposed opposite to each other; two connection columns 311 are disposed at an end of the two link mechanisms 30 facing the moving end 23, and each connection column 311 is disposed facing one of the connection plates 231 and inserted into one of the connection holes 233. That is, in the two-bar linkage 30, one end of the first bar 31 away from the second bar 33 is protruded with two connection posts 311, and the two connection posts 311 are disposed in opposite directions and inserted into the two connection holes 233, respectively.

At this time, the two connecting plates 231 clamp the first link 31 at both sides of the first link 31 of the two-link mechanism 30, and one end of the first link 31 facing the key 20 is rotatably connected to the two connecting plates 231 at the same time; in this way, the state transition process of the two-bar linkage 30 can be more stable, thereby providing a better tactile feedback experience for the user through the key 20.

Further, the side wall of the connecting plate 231 is provided with an installation notch 235 communicated with the connecting hole 233, and the connecting column 311 is guided into the connecting hole 233. Therefore, the connection process of the end of the two-link mechanism 30 facing the moving end 23 and the moving end 23 can be effectively simplified, the assembly difficulty between the two ends is reduced, and the assembly efficiency is improved.

Specifically, the mounting notch 235 is opened on the non-bearing side of the hole wall of the connection hole 233, and the width thereof is smaller than the aperture of the connection hole 233; the cross section of the connecting column 311 is similar to that of a kidney-shaped hole, the diameter of the circumference of the two arc-shaped side walls of the connecting column is equivalent to that of the connecting hole 233, and the distance between the two plane side walls of the connecting column is equivalent to the width of the mounting notch 235. Thus, when the connector post 311 is installed, one of the arc-shaped sidewalls of the connector post 311 is aligned with the installation notch 235 and pushed inward, so that the connector post 311 can be installed in the connection hole 233; in the process of rotating the connecting column 311, the two arc-shaped side walls of the connecting column 311 are in clearance fit with the hole wall of the connecting hole 233, so that the connecting column 311 can stably rotate. Understandably, the design avoids a 'rough' mode of installation by means of extrusion and elastic deformation, effectively protects related structures and avoids structural damage.

As shown in fig. 1 and fig. 2, in an embodiment of the trigger key device 100 of the present invention, one side of the base 10 facing the key 20 is provided with two opposite mounting plates 11, each mounting plate 11 is provided with a mounting hole 13, and the two mounting holes 13 are opposite to each other; the fixed end 21 is inserted between the two mounting plates 11 and is provided with a shaft hole 211 with two through ends; the trigger key device 100 further includes a shaft body 100a, the shaft body 100a penetrates through the shaft hole 211, and two ends of the shaft body are respectively inserted into the two mounting holes 13.

At this time, the two mounting plates 11 clamp the key 20 at two sides of the key 20, and the key 20 is rotatably connected with the two mounting plates 11 at the same time; in this way, the rotation process of the key 20 can be made more stable, which is beneficial for providing a better tactile feedback experience for the user. In addition, with such a design, the push button 20 can be easily and efficiently attached and detached by inserting and removing the shaft body 100 a.

Further, the trigger button device 100 further includes a button position sensor 50, wherein the button position sensor 50 is disposed between the two mounting plates 11 and faces the inner side surface of the button 20 for detecting the position of the button 20.

At this time, the position of the key 20 can be monitored by the key position sensor 50, and the position of the key 20 actually between the "bounce position" and the "sink position" after being pressed by an external force and/or being acted by the two-link mechanism 30 is obtained; therefore, the control system can know the current state of the key 20 conveniently, and the control system can make the key 20 present corresponding and accurate behaviors by accurately controlling the operation of the motor 46, so as to provide better tactile feedback experience for users.

Specifically, the key position sensor 50 employs a distance sensor such as an optical distance sensor, an infrared distance sensor, an ultrasonic distance sensor, or the like.

As shown in fig. 2, 4, 6 and 7, in an embodiment of the trigger button device 100 of the present invention, the driving assembly 40 includes a swing rod 41, the swing rod 41 has a connecting mounting end 411 and a swing end 413, the mounting end 411 is rotatably connected to the base 10, so that the swing rod 41 has a first contact position and a second contact position;

when the swing lever 41 is at the first contact position, it contacts the two-link mechanism 30 in the folded state; the swing rod 41 swings from the first contact position to the second contact position, and drives the two link mechanisms 30 to change from the folded state to the unfolded state.

Specifically, a first assembling hole 15 is opened on the surface of the base 10 facing the mounting end 411, and a second assembling hole 4111 is opened on the surface of the mounting end 411 facing the base 10; the trigger key device 100 further includes a connecting shaft 100b, one end of the connecting shaft 100b is inserted into the first assembling hole 15, and the other end is inserted into the second assembling hole 4111; thus, the swing lever 41 can swing with respect to the base 10, that is, the swing end 413 of the swing lever 41 can be displaced by being rotated about the mounting end 411. When the swing lever 41 is at the first contact position, the swing lever 41 contacts the two-link mechanism 30 in the folded state; when the swing lever 41 is in the second contact position, the swing lever 41 is in contact with the two-link mechanism 30 in the deployed state; in the process that the swing rod 41 moves from the first contact position to the second contact position, the swing rod 41 swings towards one side of the key 20 and pushes the two-link mechanism 30 to deform, so as to drive the two-link mechanism 30 to change from the folded state to the unfolded state, and further drive the key 20 to move from the "sinking position" to the "bouncing position".

It can be understood that the design of driving the two-bar linkage 30 by using the swing lever 41 is that the driving of the two-bar linkage 30 is realized by circular motion; therefore, the defect of large occupied space caused by adopting a linear driving mode can be avoided, the size of the trigger key device 100 is favorably reduced, and the trigger key device is convenient to mount and fix in electronic equipment.

Further, in order to reduce the operation energy consumption of the trigger key device 100, a pushing structure 415 is convexly disposed on a side of the swing lever 41 facing the two-bar linkage 30, and the swing lever 41 is in contact with the two-bar linkage 30 through the pushing structure 415.

In this embodiment, the pushing structure 415 is a protrusion, and the swing rod 41 contacts the two-bar mechanism 30 through the protrusion thereon to push the two-bar mechanism 30 to perform the state conversion. Of course, in other embodiments, the pushing structure 415 may be in other effective and reasonable forms, such as a rod.

It can be understood that the pushing structure 415 is provided to facilitate the contact between the swing lever 41 and the two-bar linkage 30; therefore, on one hand, the swing stroke of the swing rod 41 can be reduced, the energy required for driving the swing rod 41 to swing is reduced, and the energy consumption is reduced; on the other hand, the adverse effect of the wide-range swing of the swing lever 41 on other parts can be avoided, thereby contributing to the stability of the internal structure of the trigger key device 100.

Further, referring to fig. 8 and 9, in order to enable the trigger button device 100 to freely open or close the force feedback function, thereby more flexibly meeting the user's requirements of different periods, the trigger button device 100 is further configured as follows:

the swing rod 41 swings relative to the base 10 and also has an avoidance position; the swinging direction of the swinging rod 41 from the first contact position to the second contact position is opposite to the swinging direction of the swinging rod 41 from the first contact position to the avoidance position; the swing lever 41 is spaced apart from the two-link mechanism 30 in the escape position.

At this time, the complete state of the swing process of the swing lever 41 is:

when the swing lever 41 is in the first contact position, the swing lever 41 contacts the two-link mechanism 30 in the collapsed state;

(1) when the swing rod 41 swings towards one side of the key 20, the two-link mechanism 30 can be pushed to deform, so that the two-link mechanism 30 is driven to be converted from the folded state to the unfolded state; until the swing lever 41 comes to the second contact position, the two-link mechanism 30 is converted into the unfolded state;

(2) when the swing lever 41 swings in the direction away from the side where the key 20 is located, the contact with the two-link mechanism 30 can be released; until the swing lever 41 comes to the avoidance position and is spaced from the two link mechanisms 30 in the folded state;

that is, when the swing lever 41 swings between the first contact position and the second contact position, the force feedback function of the trigger key device 100 is turned on; when the swing lever 41 swings between the first contact position and the escape position, the force feedback function of the trigger button device 100 is turned off.

In addition, the driving manner of the swing lever 41 may be a gear 42-a rack 43 and related structures (described later); or may be, for example, a linear motor 46, an air cylinder, an electric cylinder, a screw transmission mechanism, etc. to push or pull the swing lever 41 to swing by using the sliding end which makes a linear motion therein; other reasonable and effective forms are also possible, such as further sleeving the mounting end 411 of the swing lever 41 on the output shaft of the motor 46, so as to drive the swing lever 41 to swing by using the rotation of the output shaft of the motor 46.

As shown in fig. 2, 4, 5 and 6, in an embodiment of the trigger button device 100 of the present invention, the driving assembly 40 further includes a gear 42 and a rack 43, the gear 42 is rotatably connected to the base 10, the rack 43 is disposed at the swinging end 413 and extends along a swinging path of the swinging end 413;

the gear 42 is engaged with the rack 43 to drive the swinging end 413 to swing.

Thus, as shown in fig. 6 to 9, when the gear 42 rotates relative to the base 10, the gear 42 drives the rack 43 to displace about the center of rotation of the mounting end 411 of the swing lever 41; at this time, since the rack 43 is fixed to the swing end 413 of the swing lever 41, the displacement of the rack 43 swings the swing end 413 of the swing lever 41, so that the swing lever 41 moves between the escape position and the first contact position and between the first contact position and the second contact position.

It can be understood that, in the present embodiment, a transmission manner that the gear 42 and the rack 43 are engaged with each other is adopted to drive the swing rod 41 to swing, which is beneficial to realizing a precise transmission action, so as to be beneficial to controlling a swing angle of the swing rod 41, and to controlling a thrust force applied by the swing rod 41 on the two-link mechanism 30, and finally, to providing a better tactile feedback experience for a user.

In this embodiment, the rack 43 and the swing lever 41 are integrally formed (e.g., injection molding, machining, etc.) so as to reduce the number of parts, facilitate assembly, and facilitate providing a more stable transmission relationship. Of course, in other embodiments, the rack 43 and the swing rod 41 may be two parts that are separately manufactured and then assembled together by screw connection, snap connection, mortise and tenon connection, welding, and the like.

Furthermore, it should be noted that the driving gear 42 can rotate in various ways, such as:

(1) the gear 42 is arranged on the driven wheel, and a driving wheel which is spaced from the driven wheel is arranged; a synchronous belt is sleeved on the driving wheel and the driven wheel, and the driving wheel is arranged on an output shaft of the motor 46; the forward rotation and the reverse rotation of the gear 42 can be realized by the forward rotation and the reverse rotation of the motor 46;

(2) driving the gear 42 by using other gears 42 or gear 42 groups to realize the forward rotation and reverse rotation of the gear 42;

(3) mounting the gear 42 directly on the output shaft of the motor 46; the forward rotation and the reverse rotation of the gear 42 can be realized by the forward rotation and the reverse rotation of the motor 46;

of course, besides the above three modes, those skilled in the art can select other effective and reasonable modes according to the requirements of the actual application scenario to realize the rotation of the gear 42, and the details are not repeated herein.

As shown in fig. 2, 4, 5 and 6, in an embodiment of the trigger button device 100 of the present invention, the driving assembly 40 further includes a worm gear 44, a worm 45 and a motor 46, the worm gear 44 is rotatably connected to the base 10, the gear 42 is disposed on the worm gear 44 and is coaxial with the worm gear 44 so as to rotate with the rotation of the worm gear 44;

the motor 46 is arranged on the base 10, an output shaft of the motor 46 is in transmission connection with the worm 45 to drive the worm 45 to rotate, and the worm 45 is meshed with the worm wheel 44 to drive the worm wheel 44 to rotate.

Thus, as shown in fig. 6 to 9, when the motor 46 is operated, the worm 45 is driven to rotate; when the worm 45 rotates, the worm wheel 44 can be driven to rotate; when the worm wheel 44 rotates, the driving gear 42 rotates, so that the driving of the gear 42 is realized, and the driving of the oscillating lever 41 through the gear 42-the rack 43 is realized. Understandably, such a manner is stable and reliable, and the transmission is accurate, which is beneficial for providing better tactile feedback experience for users. Moreover, such a design also facilitates the transverse placement of the motor 46, thereby facilitating the reduction of the thickness of the trigger button device 100 and facilitating the installation and fixation of the trigger button device 100 in the electronic device.

In this embodiment, the turbine 44 and the gear 42 are integrally formed (e.g., injection molded, machined, etc.) to form a unitary structure, which is beneficial to reducing the number of parts, facilitating assembly, and providing a more stable transmission relationship. Of course, in other embodiments, the worm gear 44 and the gear 42 may be separately manufactured as two parts and then assembled together by screw connection, snap connection, mortise and tenon connection, welding, and the like.

In practice, the motor 46 may be configured as follows:

the motor 46 comprises a motor 46 body and a speed reducing mechanism, the speed reducing mechanism is sleeved on an output shaft of the motor 46 body and is in transmission connection with the output shaft of the motor 46 body, and the worm 45 is in transmission connection with the output shaft of the speed reducing mechanism. At this time, the motor 46 body is in transmission connection with the worm 45 through the speed reducing mechanism, and the high rotation speed of the output shaft of the motor 46 body can be converted into the low rotation speed of the output shaft of the speed reducing mechanism through the speed reducing mechanism, so that the worm 45 obtains a better movement rate, and further the gear 42, the rack 43, the swing rod 41, the two-link mechanism 30 and the key 20 obtain a better movement rate. It will be appreciated that the reduction mechanism may be a gear 42 set or other effective form.

In particular embodiments, the motor 46 may take the form of a reduction motor 46 directly. Thus, the trigger button device 100 is not only advantageous for reducing the size thereof, facilitating the installation and fixation thereof and saving the occupied space, but also the gear motor 46 has the advantages of high efficiency, high reliability, long service life, simple and convenient maintenance, etc.

As shown in fig. 4 to 6, in an embodiment of the trigger button device 100 of the present invention, the gear 42 is located inside the rack 43.

It can be understood that the rack 43 extends along the swing path of the swing end 413 to form an arc structure, and one side of the center of the arc structure is the inner side of the rack 43; accordingly, a plurality of teeth on the rack 43 are each provided on the inner side of the rack 43, and the pinion 42 is meshed with the rack 43 from the inner side of the rack 43. At this time, by disposing the gear 42 inside the rack 43, the entire engaging structure of the worm 44, the worm 45, and the motor 46 below the gear 42 can be moved to the side where the key 20 is located, so that the structure of the trigger key device 100 is more compact, the space occupation ratio of the trigger key device 100 is reduced, and the mounting and fixing in the electronic apparatus are facilitated.

As shown in fig. 1, 2, 5 and 6, in an embodiment of the trigger key device 100 of the present invention, a rotating shaft 47 is protruded on a disk surface of the turbine 44 facing the base 10, and a through hole 17 is opened on a surface of the base 10 facing the turbine 44; the trigger button device 100 further includes a turbine rotation angle sensor 60, the turbine rotation angle sensor 60 is disposed on a side of the base 10 away from the turbine 44 and faces the through hole 17, and the rotation shaft 47 is disposed through the through hole 17 and connected to the turbine rotation angle sensor 60.

At this time, the rotation condition of the turbine 44 can be monitored by the turbine rotation angle sensor 60, so that the control system can know the current operation state of the driving assembly 40, the control system can accurately control the operation of the motor 46, more accurate transmission action can be realized, and a better tactile feedback experience can be provided for a user. Moreover, since the turbine angle sensor 60 is disposed on the side of the base 10 away from the turbine 44, the space occupying the side of the base 10 facing the turbine 44 can be avoided, and the interference of the turbine angle sensor 60 with other parts on the base 10 can be avoided; thus, not only is the overall structure stable, but also the internal structure of the trigger button device 100 can be greatly simplified, and the space occupation ratio of the trigger button device 100 is reduced.

Specifically, the turbine rotation angle sensor 60 is an angle sensor, and a detection hole is disposed in the angle sensor, and an end of the rotating shaft 47 facing away from the turbine 44 is inserted into the detection hole after penetrating through the base 10. Thus, the rotation of the turbine 44 can be calibrated by the rotation of the rotating shaft 47.

In this embodiment, the rotating shaft 47 and the turbine 44 are integrally formed (e.g., injection molding, machining, etc.) so as to reduce the number of parts, facilitate assembly, and facilitate providing a more stable transmission relationship. Of course, in other embodiments, the rotating shaft 47 and the turbine 44 may be two parts that are separately manufactured and then assembled together by means of screw connection, snap connection, mortise and tenon connection, welding, and the like.

As shown in fig. 1 and fig. 2, in an embodiment of the trigger key device 100 of the present invention, the trigger key device 100 further includes an elastic member 70, wherein one end of the elastic member 70 abuts against the base 10, and the other end abuts against the key 20, so as to drive the key 20 to reset. At this time, not only can the automatic reset of the key 20 be realized, but also the structure is simple, the manufacture is convenient, the installation is rapid, and the stability and the reliability are excellent.
