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 trigger key 10, said trigger key 10 having an initial position and a depressed position;
the elastic component 30 is arranged on the inner side of the trigger key 10, the elastic component 30 comprises a plurality of elastic members 31 which are sequentially arranged and have different stiffness coefficients, and the free end of one of the elastic members 31 is arranged towards the trigger key 10 and is used for bearing the downward pressure generated in the process that the trigger key 10 is changed from the initial position to the sinking position; and
the driving assembly 50 is arranged on the inner side of the trigger key 10, is in transmission connection with the elastic assembly 30, and is used for driving the elastic assembly 30 to move, so that the elastic member 31 capable of bearing the downward pressure of the trigger key 10 is changed among the elastic members 31.
The parts such as the trigger key 10, the elastic member 30, and the driving member 50 may be mounted on a base provided separately from the housing of the electronic apparatus 1000, or may be housed in the housing of the electronic apparatus 1000 and directly mounted on the housing. The following description will be made by taking as an example that the trigger key 10, the elastic member 30, the driving member 50, etc. are mounted on the base:
the trigger key 10 may be a key of various operation handles (for example, a game handle, etc.), a trigger of a toy gun, a key of a virtual reality device (for short, VR device), or a key of an augmented reality device (for short, AR device). The trigger key 10 is used for contacting with a finger of a user to realize force feedback, specifically (taking the example that the trigger key 10 is installed in a rotating connection manner in the present embodiment): the trigger key 10 has a fixed end 11 and a movable end 13 connected with each other, the fixed end 11 of the trigger key 10 is rotatably connected with the base, so that the movable end 13 of the trigger key 10 can rotate around the fixed end 11 to displace, and can be bounced to the highest position to obtain an initial position (as shown in fig. 2) or sunk to the lowest position to obtain a sunk position (as shown in fig. 4), and further the trigger key 10 can feed back an acting force to a finger of a user or cancel the acting force fed back to the finger of the user, thereby completing interaction with the user.
Further, the base is further provided with an elastic component 30 and a driving component 50, wherein: the elastic component 30 is movably disposed on the base, and the movable form may be a translation, a rotation (described in detail later), or other simple or complex movable form, and those skilled in the art may reasonably design according to different actual application scenarios (e.g. action scenarios such as jumping, shooting, running, etc.), and details thereof are not repeated herein. It will be understood that the purpose of the movement of the elastic assembly 30 is to enable one of the elastic elements 31 to move to a particular position (defined as the loading position); at this time, the elastic member 31 located at the bearing position may cooperate with the trigger key 10 to bear the downward force of the trigger key 10 during the movement of the trigger key 10 from the "initial position" to the "down position", thereby generating a reaction force on the trigger key 10, so that the reaction force may be transmitted to the user's finger through the trigger key 10 to realize the force feedback output.
On the other hand, since the elastic assembly 30 is driven by the driving assembly 50 to move, each elastic member 31 in the elastic assembly 30 can be switched between the bearing position and other positions, so that the elastic members 31 with different stiffness coefficients can come to the bearing position to cooperate with the trigger key 10, so as to generate reaction forces with different force value curves on the trigger key 10, thereby realizing different force feedback outputs, so as to adapt to different application scenarios, and finally providing a better tactile feedback experience for the user, thereby satisfying the sensory requirements of the user on related devices (such as various operation handles, toy guns, virtual reality devices, augmented reality devices, and the like).
In addition, it should be further noted that, if the elastic component 30 moves in a translational manner, the plurality of elastic members 31 in the elastic component 30 may be arranged along a straight line (specifically, a suitable bearing jig may be used to implement the installation and fixation of the plurality of elastic members 31), and a linear mechanism (for example, a screw rod transmission mechanism, an air cylinder, an electric cylinder, a linear motor 55, etc.) may be configured to drive the plurality of elastic members 31 to translate along the arrangement direction thereof (specifically, the linear mechanism may drive the bearing jig on which the plurality of elastic members 31 are installed to translate), so that the plurality of elastic members 31 may sequentially come to the same position (i.e., a bearing position) to form a cooperation with the trigger key 10, thereby implementing different force feedback outputs. Of course, compared to the method of using a suitable carrying fixture to simultaneously drive the plurality of elastic members 31 to move horizontally, the method can also separately drive the plurality of elastic members 31, that is: the plurality of linear mechanisms are used to drive the plurality of elastic members 31 to translate to the same position (i.e., the loading position).
As for the elastic member 31, it may be a member having elasticity, such as a spring sheet, a spring 313, a rubber pad, etc., one end of which is fixed on the carrying jig and the other end of which is disposed toward the trigger key 10 for contacting with the trigger key 10 to generate a reaction force on the trigger key 10. As for the elastic member 31, it may also be composed of a member having elasticity and other components cooperating therewith, such as the elastic member 31 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.
Regarding the movement of the trigger key 10, besides the above-mentioned rotation, it can also be a sliding manner, i.e. sliding connection with the base or sliding connection with the housing of the electronic device 1000, and sinking to the "sinking position" by sliding manner, and bouncing to the "initial position" by sliding manner.
As shown in fig. 2 to 4, in an embodiment of the force feedback device 100 of the present invention, a trigger portion 15 is protruded toward the elastic component 30 from a side of the trigger key 10 facing the elastic component 30, and a free end of the trigger portion 15 abuts against and engages with a free end of one of the elastic members 31 in a process of the trigger key 10 being changed from the initial position to the lowered position.
It can be understood that, by the trigger part 15, not only the distance between the trigger key 10 and the elastic member 31 can be shortened, which facilitates the stable matching relationship between the trigger key 10 and the elastic member 31; but also can improve the directivity of the trigger key 10, so that the trigger key 10 can more accurately form a stable matching relation with the target elastic member 31, and the occurrence of mistaken touch is avoided. In this way, the force feedback effect can be provided more stably and more accurately to the trigger key 10, thereby providing a better tactile feedback experience for the user.
As shown in fig. 2 to 4, in an embodiment of the force feedback device 100 of the present invention, a receiving space 30a for receiving a free end of the triggering portion 15 is formed between two adjacent elastic members 31.
It is understood that the receiving space 30a can be moved to align with the triggering portion 15 of the trigger key 10 by driving the elastic member 30 to move when the force feedback function is not required. Thus, during the process of moving the trigger key 10 from the initial position to the lowered position, the triggering portion 15 of the trigger key 10 will gradually approach and enter the receiving space 30a, thereby preventing the elastic member 31 from abutting against the receiving space. By means of the design, the force feedback device 100 can be flexibly switched between the on state of the force feedback function and the off state of the force feedback function, and the sudden force leakage process of the force feedback effect can be achieved, so that the use requirements of more scenes are met, and the high-quality tactile feedback experience is provided for users.
As shown in fig. 2 to 4, in an embodiment of the force feedback device 100 of the present invention, the elastic component 30 further includes a rotating disc 33, a plurality of elastic members 31 are sequentially disposed along a circumferential direction of the rotating disc 33, and the driving component 50 is connected to the rotating disc 33 in a transmission manner for driving the rotating disc 33 to rotate.
It can be understood that, in the technical solution of the present embodiment, the elastic component 30 is movable in a rotating manner, which not only realizes the switching of the positions of the plurality of elastic members 31, but also provides a plurality of stable force feedback effects for the trigger key 10; and the mode is simple, quick and reliable, and the configuration and the layout of the required driving assembly 50 are relatively simple. Furthermore, the plurality of elastic members 31 may be arranged along the circumferential direction of the turntable 33, which is also beneficial to achieve a compact layout of the force feedback device 100, and is beneficial to reduce the volume of the force feedback device 100, thereby facilitating the installation and layout thereof in the related electronic device 1000.
As shown in fig. 2 to 4, in an embodiment of the force feedback device 100 of the present invention, the elastic member 31 includes a top cover 311 and a spring 313, one end of the spring 313 is fixed on the rotation plate 33, and the other end of the spring is provided with the top cover 311 and protrudes from a side plate surface of the rotation plate 33 facing the trigger key 10 to form a free end of the elastic member 31.
It will be appreciated that the spring 313 provides a stable and reliable resilient support for the resilient member 31, and the top cover 311 provides a stable and reliable contact surface for the trigger end of the trigger key 10, which cooperate to provide a more stable engagement between the resilient member 31 and the trigger key 10, and a more stable force feedback effect, thereby providing a better tactile feedback experience for the user.
As shown in fig. 2 to 4, in an embodiment of the force feedback device 100 of the present invention, the rotary plate 33 includes a bottom plate 331, a front plate 333 and a rotary shaft 335, the bottom plate 331 and the front plate 333 are disposed opposite to each other and both sleeved on the rotary shaft 335 to rotate synchronously with the rotary shaft 335, the bottom plate 331 is located on a side of the front plate 333 opposite to the key, and the driving component 50 is connected to the rotary shaft 335 in a transmission manner for driving the rotary shaft 335 to rotate;
the top cover 311 includes a barrel 3111 and an extending portion 3113, the barrel 3111 is open at one end and closed at one end, the extending portion 3113 is formed by extending the open end of the barrel 3111, the barrel 3111 is disposed through the panel 333 and protrudes from a surface of the panel 333 facing the trigger key 10, and the extending portion 3113 abuts against a surface of the panel 333 facing the bottom plate 331;
one end of the spring 313 abuts against a surface of the bottom plate 331 facing the face plate 333, and the other end is inserted into the barrel portion 3111.
It will be appreciated that during the switching of the trigger key 10 from the initial position to the lowered position, the trigger portion 15 of the trigger key 10 will abut against the end surface of the closed end of the barrel 3111 of the top cover 311 and drive the barrel 3111 through the clearance hole of the panel 333 toward the bottom plate 331. In the process, the extension 3113 of the top cover 311 is separated from the surface of the panel 333 facing the bottom plate 331, and the spring 313 is compressed, thereby providing a force feedback effect on the trigger key 10. When the pressure applied to the trigger key 10 is removed, the spring 313 returns to the initial state, driving the barrel 3111 to pass through the relief hole of the panel 333 in a direction away from the bottom plate 331 until the extension 3113 of the top cover 311 abuts against the surface of the panel 333 facing the bottom plate 331 again. At this time, the panel 333 serves to limit the position of the top cover 311, and prevents the top cover 311 from falling off the spring 313. In this way, each elastic member 31 can be stably engaged with the trigger key 10, providing a variety of stable force feedback effects for the trigger key 10, thereby providing a better tactile feedback experience for the user.
In order to make the engagement of the elastic member 31 with the trigger key 10 more stable and the force feedback effect more stable, thereby providing a better tactile feedback experience for the user, the dial 33 may be further configured as follows:
as shown in fig. 1 and fig. 2, in an embodiment of the force feedback device 100 of the present invention, a positioning pillar 337 is protruded from a surface of the bottom plate 331 facing the front plate 333, and an end of the spring 313 facing the bottom plate 331 is sleeved on the positioning pillar 337.
In this embodiment, a plurality of positioning posts 337 are convexly disposed on a surface of the bottom plate 331 facing the panel 333, the positioning posts 337 are spaced apart along a circumference of the bottom plate 331, and each spring 313 is sleeved on one positioning post 337.
As shown in fig. 2 to 4, in an embodiment of the force feedback device 100 of the present invention, the driving assembly 50 includes a driving wheel 51, a driven wheel 53 and a motor 55, wherein the driving wheel 51 is sleeved on an output shaft of the motor 55 to rotate under the driving of the motor 55; the driven wheel 53 is coaxially connected with the turntable 33 and is in transmission connection with the driving wheel 51 so as to rotate under the driving of the driving wheel 51.
Understandably, through the cooperation of the driving wheel 51, the driven wheel 53 and the motor 55, the driving of the turntable 33 is realized, the structure is simple, the dismounting is convenient, and the advantages of strong stability and high reliability are also realized, so that the elastic part 31 corresponding to the control is fast and accurately matched with the trigger key 10, and a better tactile feedback experience is provided for a user. Moreover, the design of the embodiment can also avoid the motor 55 from blocking rotation, and prolong the service life of the motor 55, thereby increasing the reliability of the force feedback device 100.
In this embodiment, the driving wheel 51 and the driven wheel 53 are both bevel gears, the driving wheel 51 is coaxially fixed on the output shaft of the motor 55, and the driven wheel 53 is sleeved on the rotating shaft 335 of the rotating disc 33 and meshed with the driving wheel 51. Thus, the motor 55 operates to drive the driving wheel 51 to rotate; the driving wheel 51 rotates to drive the driven wheel 53 to rotate; the driven wheel 53 rotates to drive the rotating shaft 335 to rotate; the rotating shaft 335 rotates to drive the bottom plate 331 and the panel 333 to rotate; therefore, the elastic pieces 31 on the driving device are driven to rotate by taking the rotating shaft 335 as a center, the switching of positions is realized, the matching of the elastic pieces 31 with different stiffness coefficients and the trigger key 10 is realized, and different force feedback effects are generated so as to meet the requirements of different scenes.
In the present embodiment, the driving wheel 51 is located on the side of the driven wheel 53 opposite to the trigger key 10, and the motor 55 is located on the side of the driving wheel 51 facing the driven wheel 53; in this way, it is also beneficial to make the structure of the force feedback device 100 compact, and to reduce the volume of the force feedback device 100, thereby facilitating the installation and layout thereof in the electronic apparatus 1000.
Of course, in other embodiments, the driving wheel 51 and the driven wheel 53 may also assume other effective and rational forms, such as: the driving wheel 51 and the driven wheel 53 are straight gears and realize transmission through direct meshing or an intermediate gear set; another example is: the driving wheel 51 and the driven wheel 53 are belt pulleys, and transmission is realized by sleeving belts.
It can be understood that those skilled in the art can make reasonable selections according to different requirements of practical applications, and details are not described herein.
As shown in fig. 2 to 4, in an embodiment of the force feedback apparatus 100 of the present invention, the driving assembly 50 further includes a potentiometer 70, and the potentiometer 70 is connected to the output shaft of the motor 55 for monitoring the rotation process of the motor 55.

The potentiometer 70 may be a rotary potentiometer 70, and the rotary shaft 335 of the rotary potentiometer 70 is coaxially connected to the output shaft of the motor 55; thus, when the motor 55 is running, the rotary potentiometer 70 can monitor the rotation of the motor 55.
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 further includes a hall element (not shown) and a magnetic member 90, and one of the hall element and the magnetic member 90 is disposed on the trigger key 10 for monitoring the position of the trigger key 10.
