To the technical problem that the background art reflects, the utility model provides a trigger button device aims at providing more high-quality tactile feedback for the user and experiences to satisfy the user to the sense organ requirement of relevant equipment (for example all kinds of operating handle, toy gun, virtual reality equipment, augmented reality equipment etc.).

The specific structure of the trigger button device of the present invention will be described in the following embodiments:

as shown in fig. 1 to 5, 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;

a pendulum 40, wherein the pendulum 40 has a mounting end 41 and a swinging end 43 connected with each other, the mounting end 41 is rotatably connected to the base 10, and a rotation center is coaxially arranged with a rotation center of one end of the two-bar linkage 30 rotatably connected with the base 10, so that the pendulum 40 has a first contact position and a second contact position; when the pendulum 40 is in the first contact position, it contacts the two-bar linkage 30 in the closed state; the pendulum 40 swings from the first contact position to the second contact position, and drives the two link mechanisms 30 to convert from the folded state to the unfolded state; and

a driving assembly 50, wherein the driving assembly 50 is disposed on the base 10 for driving the pendulum 40 to swing between the first contact position and the second contact position.

It is understood that the base 10 can provide a stable mounting platform for the button 20, the two-bar linkage 30, the pendulum 40, the driving assembly 50, 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 pendulum 40, the driving assembly 50, etc., or may be a housing of the electronic device.

The key 20 may be a key 20 of various types of operation handles (for example, a game handle, etc.), a trigger of a toy gun, a key 20 of a virtual reality device (VR device for short), or a key 20 of an augmented reality device (AR device 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, one end of the first link 31 is rotatably connected with one end of the second link 33, one end of the first link 31 departing from the second link 33 is rotatably connected with the moving end 23 of the key 20, and one end of the second link 33 departing from the first link 31 is rotatably connected with 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 the present embodiment, when the two-bar linkage 30 is in the unfolded state, the first bar 31 and the second bar 33 are disposed at an acute angle closer to 90 ° (as shown in fig. 1), and correspondingly, the key 20 is located at the "pop-up position"; when the two-bar linkage 30 is in the folded state, the first bar 31 and the second bar 33 are disposed at an acute angle closer to 0 ° (as shown in fig. 6), and accordingly, the key 20 is located at the "down position". It should be noted that the unfolding state and the folding state of the two-link mechanism 30 are relative to themselves, that is, when the two-link mechanism 30 is converted from the unfolding state to the folding state, the included angle between the first link 31 and the second link 33 is decreasing and tends to be folded; 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, the base 10 is also provided with a pendulum 40 and a driving assembly 50: the mounting end 41 of the pendulum 40 is rotatably connected with the base 10, so that the swinging end 43 of the pendulum 40 can swing around the mounting end 41 to generate displacement, and a first contact position and a second contact position can be obtained; the drive assembly 50 is drivingly connected to the pendulum 40 to actuate the pendulum 40 between the first contact position and the second contact position. When the pendulum 40 is at the first contact position, the pendulum 40 contacts the two-bar linkage 30 in the folded state; when the pendulum 40 is in the second contact position, the pendulum 40 is in contact with the two-bar linkage 30 in the deployed state; in the process that the pendulum 40 moves from the first contact position to the second contact position, the pendulum 40 swings towards the side where the key 20 is located and pushes the two-bar linkage 30 to deform, so as to drive the two-bar linkage 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 will be understood that, when the two-bar linkage 30 is driven by the pendulum 40 and has a tendency to transform from the folded state to the unfolded state, the key 20 accordingly has a tendency to move from the "depressed position" to the "sprung 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 pendulum 40 no longer drives the two-bar linkage 30, the tendency of the two-bar linkage 30 to change from the folded state to the unfolded state is cancelled, and the tendency of the key 20 to move 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, and better tactile feedback experience is provided for the 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) are met.

Moreover, it can be understood that the pendulum 40 is used to drive the two-bar linkage 30, that is, the two-bar linkage 30 is driven 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.

The driving unit 50 may be a motor 57, a worm 55, a worm wheel 53, a gear 51, a rack 47, and the like (described later); the linear driving assembly 50 (e.g., the linear motor 57, 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 50, and drive the two-link mechanism to switch between the folded state and the unfolded state; other reasonable and effective forms are also possible, such as that the end of the second link 33 of the two-link mechanism 30 facing away from the first link 31 is further mounted on the output shaft of the motor 57, so that the second link 33 is driven to swing by the rotation of the output shaft of the motor 57, thereby driving the two-link mechanism 30 to convert between the folded state and the unfolded state.

As shown in fig. 1 to 5, in an embodiment of the trigger button device 100 of the present invention, two opposite connecting plates 231 are disposed on a side of the moving end 23 facing the two-bar linkage 30, each connecting plate 231 is provided with a connecting hole 233, and the two connecting 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 to 5, in an embodiment of the trigger button device 100 of the present invention, two opposite mounting plates 11 are disposed on one side of the base 10 facing the button 20, each mounting plate 11 has a mounting hole 13, and the two mounting holes 13 are disposed 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 60, wherein the button position sensor 60 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 60, 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 show corresponding and accurate behaviors by accurately controlling the operation of the motor 57 conveniently, so as to provide better tactile feedback experience for users.

Specifically, the key position sensor 60 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. 1 to 5, in an embodiment of the trigger button device 100 of the present invention, an end of the first link 31 facing away from the second link 33 and the swinging end 43 are respectively located at two sides of the second link 33;

a pushing structure 45 is convexly arranged on one side of the pendulum 40 facing the second connecting rod 33, and the pendulum 40 is in contact with the second connecting rod 33 through the pushing structure 45.

In this embodiment, the pendulum 40 has a substantially fan-shaped structure having two sides extending from the mounting end 41 to the swinging end 43, one side facing the key 20 and the other side facing away from the key 20. At this time, a pushing structure 45 is protruded on one side of the fan-shaped structure facing the key 20, and the pushing structure 45 has a pushing surface 451. When the pendulum 40 is in the first contact position, the pushing surface 451 contacts with a side of the second link 33 opposite to the key 20; in the process that the pendulum 40 moves from the first contact position to the second contact position, the pushing surface 451 is always in contact with the side of the second link 33 opposite to the key 20; that is, in the process of the pendulum 40 moving from the first contact position to the second contact position, the pushing surface 451 pushes the two-bar linkage 30 to deform, so as to drive the two-bar linkage 30 to change from the folded state to the unfolded state, and further drive the button 20 to move from the "sinking position" to the "bouncing position".

Of course, in other embodiments, the pushing structure 45 can be in other effective and reasonable forms, such as a rod, a bump, a hemisphere, etc.

It can be understood that the pushing structure 45 is provided to facilitate the contact between the pendulum 40 and the two-bar linkage 30; therefore, on one hand, the swinging stroke of the pendulum bob 40 can be reduced, the energy required for driving the pendulum bob 40 to swing is reduced, and the energy consumption is reduced; on the other hand, the pendulum 40 can be prevented from being badly influenced by the large-scale swing to other parts, thereby facilitating the stability of the internal structure of the trigger button device 100.

Moreover, it can be understood that, by coaxially arranging the mounting end 41 of the pendulum 40 and the end of the second link 33 away from the first link 31, the pendulum 40 and the second link 33 can synchronously swing without generating relative displacement therebetween, so that the problem of frictional resistance can be effectively solved, the pendulum 40 can drive the two-link mechanism 30 more stably and reliably, and a better tactile feedback experience can be provided for a user.

As shown in fig. 1 to 5, in an embodiment of the trigger button device 100 of the present invention, the trigger button device 100 further includes a connecting shaft 100b, one end of the connecting shaft 100b is inserted into the base 10, one end of the second connecting rod 33 deviating from the first connecting rod 31 is rotatably sleeved on the connecting shaft 100b, the mounting end 41 is rotatably sleeved on the connecting shaft 100b, and one end of the second connecting rod 33 deviating from the first connecting rod 31 is located between the base 10 and the mounting end 41.

Specifically, a first assembly hole 15 is opened on the surface of the base 10 facing the mounting end 41, a second assembly hole 411 is opened on the surface of the mounting end 41 facing the base 10, and a through hole 331 is opened on the end of the second link 33 away from the first link 31; one end of the connecting shaft 100b is inserted into the first fitting hole 15, and the other end thereof is inserted into the second fitting hole 411 after passing through the through hole 331.

Understandably, with such a design, the end of the second link 33 away from the first link 31 can be rotatably connected with the base 10 through one connecting shaft 100b, and the mounting end 41 of the pendulum 40 can be rotatably connected with the base 10, so that the structure is simple, the assembly is fast, and the stability and the reliability are excellent. Moreover, the mounting end 41 of the pendulum 40 and the end of the second link 33 away from the first link 31 are rotatably connected to the same connecting shaft 100b, which is also beneficial to improving the coaxiality of the pendulum 40 and the second link 33, thereby improving the operation stability of the pendulum 40 and the second link 33, avoiding relative displacement between the two and avoiding friction.

Further, in order to make the contact between the pendulum 40 and the second link 33 more stable, so as to facilitate the pendulum 40 to form a stable driving force for the two-link mechanism 30, and to facilitate providing a better tactile feedback experience for the user, the second link 33 may be further configured as follows:

as shown in fig. 1 to 5, in an embodiment of the trigger button device 100 of the present invention, a limiting surface 333 is formed on a side of the second link 33 facing away from the base 10, and the limiting surface 333 is disposed facing the pendulum 40; when the pendulum 40 is in the first contact position, the second link 33 contacts the pendulum 40 through the limiting surface 333.

Specifically, when the pendulum 40 is in the first contact position, the pushing surface 451 is in contact with a side of the second link 33 facing away from the key 20, and the limiting surface 333 is in contact with a side of the pendulum 40 facing the key 20; in addition, in the process that the pendulum bob 40 moves from the first contact position to the second contact position, the pushing surface 451 is always in contact with one side of the second connecting rod 33, which is back to the key 20, and the limiting surface 333 is always in contact with one side of the pendulum bob 40, which faces the key 20; that is, in the process that the pendulum 40 moves from the first contact position to the second contact position, the pushing surface 451 pushes the two-bar linkage 30 to deform, and the limiting surface 333 bears the pushing force from the side of the pendulum 40 facing the key 20 to deform the two-bar linkage 30, so as to drive the two-bar linkage 30 to change from the folded state to the unfolded state, and further drive the key 20 to move from the "down position" to the "up position".

Further, as shown in fig. 1, 6, 7 and 8, 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 use requirements at different times, the trigger button device 100 is further configured as follows:

the pendulum 40 swings relative to the base 10 and also has an escape position; the swinging direction of the pendulum bob 40 from the first contact position to the second contact position is opposite to the swinging direction of the pendulum bob 40 from the first contact position to the avoidance position; the pendulum 40 is spaced from the two-bar linkage 30 when in the retracted position.

At this time, the complete state of the swinging process of the pendulum 40 is:

when the pendulum 40 is in the first contact position, the pendulum 40 is in contact with the two-bar linkage 30 in the collapsed state;

(1) when the pendulum 40 swings towards the side of the key 20, it can push the two-link mechanism 30 to deform, thereby driving the two-link mechanism 30 to change from the folded state to the unfolded state; until the pendulum 40 comes to the second contact position, and accordingly, the two-link mechanism 30 is converted into the unfolded state;

(2) when the pendulum 40 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 pendulum 40 comes to the escape position to be spaced apart from the two-link mechanism 30 in the unfolded state;

that is, when the pendulum 40 swings between the first contact position and the second contact position, the force feedback function of the trigger button device 100 is turned on; while the pendulum 40 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, it should be noted that the pendulum 40 may be driven by a gear 51, a rack 47 and related structures (described later); it can also be, for example, a linear motor 57, a cylinder, an electric cylinder, a screw transmission mechanism, etc. to push or pull the pendulum 40 to swing by using the sliding end which makes a linear motion therein; other reasonable and effective forms are also possible, such as further mounting the mounting end 41 of the pendulum 40 to the output shaft of the motor 57, so that the pendulum 40 is driven to swing by the rotation of the output shaft of the motor 57.

As shown in fig. 1 to 5, in an embodiment of the trigger button device 100 of the present invention, the end surface of the swing end 43 is provided with a rack 47 extending along the swing path of the swing end 43;

the driving assembly 50 includes a gear 51, and the gear 51 is rotatably connected to the base 10 and engaged with the rack 47 to drive the swinging end 43 to swing.

Thus, when the gear 51 rotates relative to the base 10, the gear 51 drives the rack 47 to displace about the center of rotation of the mounting end 41 of the pendulum 40; the displacement of the rack 47 drives the swinging end 43 of the pendulum 40 to swing, so that the pendulum 40 moves between the avoidance 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 51 and the rack 47 are engaged is adopted to drive the pendulum 40 to swing, which is beneficial to realize a precise transmission action, thereby being beneficial to controlling the swing angle of the pendulum 40, being beneficial to controlling the thrust exerted by the pendulum 40 on the two-bar linkage 30, and finally being beneficial to providing a better tactile feedback experience for a user.

In this embodiment, the rack 47 and the pendulum bob 40 are integrally formed (e.g., injection molding, machining, etc.) to form an integral 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 rack 47 and the pendulum 40 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.

In addition, it should be noted that the driving gear 51 may rotate in various ways, such as:

(1) the gear 51 is arranged on a driven wheel, and a driving wheel which is separated 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 57; the forward rotation and the reverse rotation of the gear 51 can be realized by the forward rotation and the reverse rotation of the motor 57;

(2) driving the gear 51 by using other gears 51 or gear 51 groups to realize the forward rotation and reverse rotation of the gear 51;

(3) the gear 51 is directly mounted on the output shaft of the motor 57; the forward rotation and the reverse rotation of the gear 51 can be realized by the forward rotation and the reverse rotation of the motor 57;

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 51, and the details are not repeated herein.

As shown in fig. 1 to 5, in an embodiment of the trigger button device 100 of the present invention, the driving assembly 50 further includes a worm wheel 53, a worm 55 and a motor 57, the worm wheel 53 is rotatably connected to the base 10, the gear 51 is disposed on the worm wheel 53 and is coaxial with the worm wheel 53 so as to rotate with the rotation of the worm wheel 53;

the motor 57 is disposed on the base 10, an output shaft of the motor 57 is in transmission connection with the worm 55 to drive the worm 55 to rotate, and the worm 55 is meshed with the worm wheel 53 to drive the worm wheel 53 to rotate.

Thus, when the motor 57 is operated, the worm 55 is driven to rotate; when the worm 55 rotates, the worm wheel 53 is driven to rotate; when the worm wheel 53 rotates, the drivable gear 51 rotates, thus effecting the driving of the gear 51 and of the oscillating weight 40 through the gear 51-the rack 47. 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 is also beneficial to realizing the transverse arrangement of the motor 57, thereby being beneficial to reducing the thickness of the trigger key device 100 and further being convenient for installing and fixing the trigger key device 100 in the electronic equipment.

In this embodiment, the worm wheel 53 and the gear 51 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 worm gear 53 and the gear 51 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.

In practical applications, the motor 57 may be configured as follows:

At this time, the motor 57 body is in transmission connection with the worm 55 through the speed reducing mechanism, and the high rotation speed of the output shaft of the motor 57 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 55 obtains a better movement rate, and further the gear 51, the rack 47, the pendulum 40, 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 51 set or other effective form.

In particular, the motor 57 may be in the form of a geared motor 57.
