With the continuous development of peripheral devices such as various operation handles, virtual reality devices, augmented reality devices and the like in recent years, the sensory requirements of users on the use of the peripheral devices are also increasing. As such, how to meet the sensory requirements of users on related devices (such as various operation handles, virtual reality devices, augmented reality devices, etc.) is also a problem to be solved by research personnel.
In view of the above technical problems, the present invention proposes a trigger button device 100, which aims to provide a better haptic feedback experience for a user, so as to meet the sensory requirements of the user on related devices (such as various operation handles, virtual reality devices, augmented reality devices, etc.).
The specific structure of the trigger button apparatus 100 of the present invention will be described in the following in the specific embodiment:
as shown in fig. 1, 2,6 and 7, in one embodiment of the trigger button device 100 of the present invention, the trigger button device 100 includes:
A base 10;
A key 20, wherein the key 20 has 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 sprung position and a sunk position;
The two-bar linkage 30, one end of the two-bar linkage 30 is rotatably connected to the moving end 23, the other end is rotatably connected to the base 10, the two-bar linkage 30 has an unfolded state and a folded state, the two-bar linkage 30 drives the key 20 to be positioned at a bouncing position in the unfolded state, and the two-bar linkage 30 drives the key 20 to be positioned at a sinking position in the folded state; and
The driving assembly 40 is disposed on the base 10, and is used for driving the two link mechanisms 30 to convert from the folded state to the unfolded state.
As can be appreciated, the base 10 can provide a stable mounting platform for the keys 20, the two-bar linkage 30, the drive assembly 40, etc.; the base 10 may be a component that is specifically provided for mounting the key 20, the two-bar linkage 30, the driving unit 40, etc. and is independent of the electronic device casing, or may be used as the electronic device casing.
The key 20 may be a key of various operation handles (such as a game handle, etc.), a key of a virtual reality device (abbreviated as VR device), or a key of an augmented reality device (abbreviated as AR device); the keys 20 are for contact with the user's finger: 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 "pop up" to the highest position to obtain "pop-up position", or "sink" to the lowest position to obtain "sink position", so that the key 20 can feed back acting force to the finger of the user, or cancel the acting force fed back to the finger of the user, and further complete interaction with the user.
Two link mechanisms 30 are further connected between the moving end 23 of the key 20 and the base 10, namely one end of each link mechanism 30 is rotationally connected with the moving end 23 of the key 20, and the other end of each link mechanism 30 is rotationally connected with the base 10. The method 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 with one end of the second link 33, one end of the first link 31, which is away from the second link 33, is hinged with 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 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-bar linkage". In the present embodiment, when the two link mechanisms 30 are in the unfolded state, the first link 31 and the second link 33 are disposed at an obtuse angle (as shown in fig. 6), and accordingly, 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 the "sinking position". It should be noted that, the unfolded state and the folded state of the two link mechanisms 30 are relative to each other, that is, when the two link mechanisms 30 are converted from the unfolded state to the folded state, the included angle between the first link 31 and the second link 33 is smaller and the two link mechanisms tend to be folded; conversely, when the two link mechanisms 30 are converted from the folded state to the unfolded state, the included angle between the first link 31 and the second link 33 is increased and the two link mechanisms are unfolded; the actual size of the included angle between the first link 31 and the second link 33 can be set reasonably by those skilled in the art according to specific application conditions, and is not limited.
Further, the base 10 is further provided with a driving assembly 40, and the driving assembly 40 can drive the two-bar linkage 30 to change from the folded state to the unfolded state. As can be appreciated, when the two-bar linkage 30 is driven by the driving assembly 40 and has a tendency to transition from the collapsed state to the expanded state, the key 20 accordingly has a tendency to move from the "sinking position" to the "bouncing position"; at this time, if the user's finger presses the key 20, the key 20 will feedback the acting force to the user's finger, thereby realizing the force feedback function. When the driving assembly 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 time, the force fed back to the user's finger is removed, and the key 20 is moved from the "pop-up position" to the "sink position" by the user's press. Thus, the interaction with the fingers of the user can be completed, more realistic haptic feedback experience is provided for the user, and finally the sensory requirements of the user on related devices (such as various operation handles, virtual reality devices, augmented reality devices and the like) are met.
It should be noted that the driving assembly 40 may be a swing lever 41 and related structures (which will be described later); the driving assembly 40 may also be a linear driving assembly (such as a linear motor 46, a cylinder, an electric cylinder, a screw rod transmission mechanism, etc.), so as to push or pull the two link mechanisms 30 by using the sliding end of the linear driving assembly 40 to make a linear motion, and drive the two link mechanisms to convert from a folded state to an unfolded state; other reasonable and effective forms are also possible, for example, one end of the second link 33 of the two-link mechanism 30, which is far 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 using the rotation of the output shaft of the motor 46, and the two-link mechanism 30 is driven to be converted 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 oppositely disposed connecting plates 231 are disposed on a side of the movable end 23 facing the two link mechanisms 30, each connecting plate 231 is provided with a connecting hole 233, and the two connecting holes 233 are oppositely disposed; two connecting posts 311 are disposed at one end of the two link mechanisms 30 facing the moving end 23, and each connecting post 311 is disposed facing one connecting plate 231 and inserted into one connecting hole 233. That is, two connecting posts 311 are protruding from one end of the first link 31 facing away from the second link 33 in the two-link mechanism 30, and the two connecting posts 311 are disposed in opposite directions and are respectively inserted into the two connecting holes 233.
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 simultaneously connected with the two connecting plates 231 in a rotating manner; in this way, the state transition process of the two-bar linkage 30 can be more stable, thereby being beneficial to providing better haptic feedback experience for users through the keys 20.
Further, a mounting notch 235 is formed on a side wall of the connecting plate 231 and is connected to the connecting hole 233, so as to guide the connecting post 311 into the connecting hole 233. Therefore, the connecting process between one end of the two link mechanisms 30 facing the movable end 23 and the movable 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 formed on the non-bearing side of the wall of the connecting hole 233, and its width is smaller than the aperture of the connecting hole 233; the cross-sectional shape of the connecting post 311 is similar to that of the waist-shaped hole, the diameter of the circumference of the two arc-shaped side walls is equal to that of the connecting hole 233, and the distance between the two plane side walls is equal to the width of the mounting notch 235. Thus, when the connecting column 311 is installed, one of the arc-shaped side walls of the connecting column 311 is aligned with the installation notch 235 and pushed inwards, so that the connecting column 311 can be installed in the connecting 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. It will be appreciated that such a design avoids the "rough" way of mounting by means of extrusion and elastic deformation, effectively protecting the relevant structure and avoiding structural damage.
As shown in fig. 1 and 2, in an embodiment of the trigger button device 100 of the present invention, two opposite mounting plates 11 are disposed on a side of the base 10 facing the button 20, each mounting plate 11 is provided with 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 ends penetrating; the trigger button device 100 further includes a shaft body 100a, where the shaft body 100a is disposed 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 both sides of the key 20, and the key 20 is simultaneously connected with the two mounting plates 11 in a rotating manner; in this way, the rotation process of the key 20 can be made more stable, thereby facilitating a better haptic feedback experience for the user. In addition, by the above design, the key 20 can be easily and efficiently attached and detached by pulling and inserting the shaft body 100 a.
Further, the trigger key device 100 further includes a key position sensor 50, where the key position sensor 50 is disposed between the two mounting plates 11 and faces the inner side surface of the key 20, so as to detect the position of the key 20.
At this time, the position of the key 20 can be monitored by the key position sensor 50, so as to obtain the position between the "bouncing position" and the "sinking position" after the key 20 is pressed by the external force and/or acted by the two-bar linkage 30; thus, the control system is convenient to know the current state of the key 20, and the control system is convenient to accurately control the operation of the motor 46 to enable the key 20 to present corresponding and accurate behaviors, so that better haptic feedback experience is provided 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 lever 41, the swing lever 41 has a mounting end 411 and a swing end 413 connected to each other, and the mounting end 411 is rotatably connected to the base 10, so that the swing lever 41 has a first contact position and a second contact position;
The swinging rod 41 contacts with the two link mechanisms 30 in the folded state when in the first contact position; the swing rod 41 swings from the first contact position to the second contact position, so as to drive the two link mechanisms 30 to be converted from the folded state to the unfolded state.
Specifically, a surface of the base 10 facing the mounting end 411 is provided with a first assembly hole 15, and a surface of the mounting end 411 facing the base 10 is provided with a second assembly hole 4111; the trigger button device 100 further includes a connecting shaft 100b, wherein one end of the connecting shaft 100b is inserted into the first assembly hole 15, and the other end is inserted into the second assembly hole 4111; in this way, 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 rotating about the mounting end 411. When the swing lever 41 is at the first contact position, the swing lever 41 is in contact with the two link mechanisms 30 in the folded state; when the swing lever 41 is at the second contact position, the swing lever 41 is in contact with the two-bar linkage 30 in the unfolded state; in the process of moving the swing lever 41 from the first contact position to the second contact position, the swing lever 41 swings towards the side where the key 20 is located and pushes the two link mechanisms 30 to deform, so as to drive the two link mechanisms 30 to convert 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 swinging rod 41 is that the driving of the two-bar linkage 30 is realized by circular motion; in this way, the defect of large occupied space caused by adopting a linear driving mode can be avoided, the size of the trigger button device 100 is reduced, and the installation and the fixation of the trigger button device in electronic equipment are facilitated.
Further, in order to reduce the operation energy consumption of the trigger button device 100, a pushing structure 415 is protruding from a side of the swing rod 41 facing the two-bar linkage 30, and the swing rod 41 contacts with the two-bar linkage 30 through the pushing structure 415.
In this embodiment, the pushing structure 415 is a protruding portion, and the swing lever 41 contacts the two link mechanisms 30 through the protruding portion thereon to push the two link mechanisms 30 to perform state transformation. Of course, in other embodiments, the pushing structure 415 may take other effective and reasonable forms, such as a rod.
As can be appreciated, the pushing structure 415 can make the contact between the swing rod 41 and the two-bar linkage 30 easier; thus, on one hand, the swinging stroke of the swinging rod 41 can be reduced, the energy required for driving the swinging rod 41 to swing is reduced, and the energy consumption is reduced; on the other hand, the swing lever 41 can be prevented from swinging in a large range to cause adverse effects on other parts, so that the stability of the internal structure of the trigger button device 100 is facilitated.
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, so as to more flexibly meet the use requirements of users in different periods, the trigger button device 100 is further configured as follows:
The swinging rod 41 swings relative to the base 10 and also has a 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 avoiding position; the swing lever 41 is spaced from the two-bar linkage 30 in the retracted position.
At this time, the complete state of the swing process of the swing lever 41 is:
when the swing lever 41 is at the first contact position, the swing lever 41 is in contact with the two-bar linkage 30 in the folded state;
(1) When the swinging rod 41 swings towards the side where the key 20 is located, the two link mechanisms 30 can be pushed to deform, so that the two link mechanisms 30 are driven to be converted from a furled state to an unfolded state; until the swing lever 41 comes to the second contact position, the two link mechanisms 30 are correspondingly converted into the unfolded state;
(2) When the swinging rod 41 swings towards the direction away from the side where the key 20 is located, the swinging rod can be separated from contact with the two-bar linkage 30; until the swing lever 41 comes to avoid the yielding position and is separated from the two link mechanisms 30 in the furled 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; and when the swing lever 41 swings between the first contact position and the escape position, the force feedback function of the trigger button apparatus 100 is turned off.
Note that, the driving manner of the swing lever 41 may be a gear 42, a rack 43, and related structures (which will be described later); or may be, for example, a linear motor 46, an air cylinder, an electric cylinder, a screw transmission mechanism, or the like, to push or pull the swing lever 41 to swing with a sliding end in which linear motion is performed; other reasonable and effective forms are also possible, for example, the mounting end 411 of the swinging rod 41 is further sleeved on the output shaft of the motor 46, so that the swinging rod 41 is driven to swing by 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, and 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 gear 43 to drive the swing 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 around the rotation center 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 drives the swing end 413 of the swing lever 41 to swing, so that the swing lever 41 moves between the avoidance position and the first contact position and between the first contact position and the second contact position.
It can be appreciated that the present embodiment adopts the transmission manner of meshing the rack 43 and the gear 42 to drive the swing rod 41 to swing, which is beneficial to realizing accurate transmission motion, thereby being beneficial to controlling the swing angle of the swing rod 41, controlling the thrust force exerted on the two-bar linkage 30 by the swing rod 41, and finally providing better haptic feedback experience for users.
In this embodiment, the rack 43 and the swing rod 41 are integrally formed (e.g. injection molding, machining, etc.), which is advantageous in reducing the number of parts, facilitating assembly, and providing a more stable driving relationship. Of course, in other embodiments, the rack 43 and the swing rod 41 may be two separately manufactured components, and then assembled together by screw connection, snap connection, mortise-tenon connection, welding, etc.
In addition, it should be noted that there are various ways to rotate the driving gear 42, for example:
(1) A gear 42 is mounted on the driven wheel and a driving wheel spaced from the driven wheel is provided; 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 motor 46 can realize the forward rotation and the reverse rotation of the gear 42;
(2) Driving the gear 42 with other gears 42 or groups of gears 42 to achieve forward and reverse rotation of the gear 42;
(3) Mounting gear 42 directly on the output shaft of motor 46; the forward rotation and the reverse rotation of the motor 46 can realize the forward rotation and the reverse rotation of the gear 42;
Of course, besides the above three modes, a person skilled in the art may select other effective and reasonable modes according to the requirements of the actual application scenario, so as to realize the rotation of the gear 42, which is not described 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 wheel 44, a worm 45 and a motor 46, the worm wheel 44 is rotatably connected to the base 10, and the gear 42 is disposed on the worm wheel 44 and coaxially disposed with the worm wheel 44 so as to rotate along with the rotation of the worm wheel 44;
The motor 46 is disposed 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 gear 42 can be driven to rotate, thereby realizing the driving of the gear 42 and the driving of the swing rod 41 through the gear 42 and the rack 43. It will be appreciated that in this manner, a stable and reliable, accurate transmission is advantageous for providing a better haptic feedback experience to the user. Moreover, such a design is also advantageous for achieving a transverse placement of the motor 46, thereby facilitating a reduction in the thickness of the trigger button apparatus 100, and thus facilitating the installation and fixation of the trigger button apparatus 100 in an electronic device.
In this embodiment, the worm gear 44 and the gear 42 are integrally formed (e.g., injection molded, machined, etc.), which is advantageous in reducing the number of parts, facilitating assembly, and providing a more stable driving relationship. Of course, in other embodiments, the worm gear 44 and the gear 42 may be two separately manufactured components, and then assembled together by screw connection, snap connection, mortise-tenon connection, welding, etc.
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 the gear 42, the rack 43, the swinging rod 41, the two-bar mechanism 30 and the key 20 all obtain a better movement rate. It will be appreciated that the reduction mechanism may be in the form of a set of gears 42 or other effective form.
In particular embodiments, the motor 46 may take the form of a gear motor 46 directly. Thus, the size of the trigger button device 100 is reduced, the installation and fixation are facilitated, the occupied space is saved, and the gear motor 46 has the advantages of high efficiency, high reliability, long service life, simple maintenance and the like.

It can be appreciated that the rack 43 extends along the swing path of the swing end 413 to form an arc structure, and the side of the arc structure where the center of the circle is located is the inner side of the rack 43; accordingly, the plurality of teeth on the rack gear 43 are provided on the inner side of the rack gear 43, and the gear 42 is engaged with the rack gear 43 from the inner side of the rack gear 43. At this time, by disposing the gear 42 inside the rack 43, the whole of the matching structure of the worm gear 44, the worm 45 and the motor 46 below the gear 42 can be moved to the side of the key 20, 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 installation and the fixation of the trigger key device 100 in the electronic device are facilitated.

At this time, the rotation condition of the worm wheel 44 can be monitored by the worm wheel rotation angle sensor 60, so that the control system can know the current running state of the driving assembly 40, and can accurately control the running of the motor 46, thereby realizing more accurate transmission action and providing better haptic feedback experience for users. Moreover, because the worm wheel rotation angle sensor 60 is arranged on one side of the base 10, which is far away from the worm wheel 44, the space occupying one side of the base 10, which faces the worm wheel 44, can be avoided, and the interference of the worm wheel rotation angle sensor 60 to other parts on the base 10 can be avoided; thus, not only is the stability of the overall structure facilitated, 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 can be reduced.
Specifically, the worm wheel rotation angle sensor 60 is an angle sensor having a detection hole disposed therein, and an end of the rotation shaft 47 facing away from the worm wheel 44 penetrates the base 10 and is inserted into the detection hole. Thus, the rotation of the worm wheel 44 can be calibrated by the rotation of the rotation shaft 47.
In this embodiment, the rotation shaft 47 and the worm wheel 44 are integrally formed (e.g. injection molded, machined, etc.), which is advantageous in reducing the number of parts, facilitating assembly, and providing a more stable driving relationship.
