The force feedback device can be used in various technical fields such as medical treatment, modeling, training, virtual assembly, robot control, games, entertainment, VR and the like, so that feedback force is provided for a user, experience of the user is enhanced, and for convenience of description, the embodiment of the application is only exemplified by the fact that the force feedback device is applied to a handle.
Referring to fig. 1 to 3, in some embodiments of the present application, a force feedback device 1 includes a housing 10, a transmission assembly 20, a trigger 30, and a driving assembly 50, where the transmission assembly 20 is disposed in the housing 10, the transmission assembly 20 includes a first transmission member 21 and a second transmission member 22, the first transmission member 21 is sleeved outside the second transmission member 22 and is in threaded transmission with the second transmission member 22, at least part of the trigger 30 is disposed in the housing 10, an elastic member 40 is disposed between the trigger 30 and the second transmission member 22, the trigger 30 can reciprocate along an axial direction of the second transmission member 22, and during a movement of the trigger 30 toward the second transmission member 22, the elastic member 40 can be pressed and abutted against the first transmission member 21, and the driving assembly 50 is connected with the second transmission member 22 and is used for driving the second transmission member 22 to rotate.
Specifically, the housing 10 is internally formed with a receiving chamber in which the transmission assembly 20, part of the trigger 30, and part of the driving assembly 50 may be disposed, and provide a feedback force in a state of pressing the trigger 30 by a transmission fit. Wherein, the casing 10 includes a first casing part 11 and a second casing part 12 which are detachably connected, and the first casing part 11 and the second casing part 12 enclose a containing cavity, thereby facilitating disassembly and assembly. Because the first transmission member 21 is sleeved outside the second transmission member 22 and is in threaded transmission with the second transmission member 22, when the driving assembly 50 drives the second transmission member 22 to rotate, the second transmission member 22 can drive the first transmission member 21 to move relative to the second transmission member 22 along the axial direction of the second transmission member 22, so that the distance between the first transmission member 21 and the trigger 30 is adjusted, and the feedback force form received by the trigger 30 is adjusted.
The first transmission member 21 can reciprocate along the axial direction of the second transmission member 22 under the action of the driving assembly 50 and the second transmission member 22, and has a first limit position and a second limit position, and an intermediate position between the first limit position and the second limit position. When the first transmission piece 21 is in the first extreme position, the first transmission piece 21 is far away from the trigger 30 and can not move continuously in the direction far away from the trigger 30, when the first transmission piece 21 is in the second extreme position, the first transmission piece 21 is located at one end of the second transmission piece 22 close to the trigger 30 and is in fit connection with the trigger 30, and when the first transmission piece 21 is in the middle position, the first transmission piece 21 and the trigger 30 are arranged at intervals or in fit connection and can move continuously in the direction far away from the trigger 30.
According to the force feedback device 1 of the present application, since the elastic member 40 is disposed between the second transmission member 22 and the trigger 30, the force feedback action of the elastic member 40 is always received during the pressing of the trigger 30.
As shown in fig. 1, the driving assembly 50 does not provide driving force, the first transmission member 21 is at the first limit position, the first transmission member 21 is spaced from the trigger 30, and the force feedback action of the elastic member 40 is only applied during the pressing of the trigger 30 until the trigger 30 moves to the position shown in fig. 2. If the driving assembly 50 still does not provide driving force at this time, the pressing trigger 30 is only subjected to the force feedback action of the elastic member 40, and if the driving assembly 50 provides driving force and the first transmission member 21 has a tendency to move toward the direction approaching the trigger 30 at this time, the pressing trigger 30 is subjected to the force feedback action of not only the elastic member 40 but also the driving force provided by the driving assembly 50.
When the driving assembly 50 does not provide the driving force and the trigger 30 moves to abut against the first transmission member 21, and the trigger 30 can drive the first transmission member 21 to move toward the second transmission member 22, the pressing trigger 30 is not only subjected to the force feedback action of the elastic member 40, but also to the friction force between the first transmission member 21 and the second transmission member 22 due to the threaded transmission between the first transmission member 21 and the second transmission member 22.
As shown in fig. 4, at this time, the first transmission member 21 is at the second limit position, the first transmission member 21 is abutted against the trigger 30, and the trigger 30 can drive the first transmission member 21 to move towards the second transmission member 22 continuously. If the driving assembly 50 does not provide driving force at this time, the first transmission member 21 can move along the axial direction of the second transmission member 22 during the process of pressing the trigger 30, and friction exists between the first transmission member 21 and the threaded transmission of the second transmission member 22, so that the pressing trigger 30 is subjected to not only the force feedback action of the elastic member 40, but also the friction between the first transmission member 21 and the second transmission member 22. If the driving unit 50 provides driving force at this time, the pressing trigger 30 is subjected to not only the force feedback action of the elastic member 40 but also the friction force between the first transmission member 21 and the second transmission member 22, and the driving force of the driving unit 50.
As shown in fig. 5, the first transmission member 21 is in the middle, the first transmission member 21 is abutted against the trigger 30, and the trigger 30 can drive the first transmission member 21 to move towards the second transmission member 22 continuously. If the driving assembly 50 does not provide driving force at this time, the first transmission member 21 can move along the axial direction of the second transmission member 22 during the process of pressing the trigger 30, and friction exists between the first transmission member 21 and the threaded transmission of the second transmission member 22, so that the pressing trigger 30 is subjected to not only the force feedback action of the elastic member 40, but also the friction between the first transmission member 21 and the second transmission member 22. If the driving unit 50 provides driving force at this time, the pressing trigger 30 is subjected to not only the force feedback action of the elastic member 40 but also the friction force between the first transmission member 21 and the second transmission member 22, and the driving force of the driving unit 50.
As shown in fig. 6, the first transmission member 21 is in the middle, the first transmission member 21 and the trigger 30 are spaced apart, and the trigger 30 can move a certain distance to drive the first transmission member 21 to move towards the second transmission member 22. If the driving assembly 50 does not provide driving force at this time, the trigger 30 moves toward the direction of the first transmission member 21 during the process of pressing the trigger 30, and only receives force feedback action of the elastic member 40 during the process, when the trigger 30 moves to abut against the first transmission member 21, as shown in fig. 5, and continues to press the trigger 30, if the driving assembly 50 does not provide driving force at this time, the first transmission member 21 can move along the axial direction of the second transmission member 22 during the process of pressing the trigger 30, and friction exists between the first transmission member 21 and the threaded transmission of the second transmission member 22, so that the pressing trigger 30 receives force feedback action of not only the elastic member 40, but also friction between the first transmission member 21 and the second transmission member 22. As shown in fig. 5, if the driving unit 50 provides driving force at this time, the pressing trigger 30 is subjected to not only force feedback of the elastic member 40 but also friction force between the first transmission member 21 and the second transmission member 22 and driving force of the driving unit 50.
According to the force feedback device 1 provided by the application, the feedback force can be effectively regulated, so that the force value range of the feedback force is improved, and the experience of a user is improved.
In some embodiments of the present application, as shown in fig. 2 and 3, one of the inner wall surface of the housing 10 and the outer wall surface of the first transmission member 21 is provided with a first rib 212, and the other of the inner wall surface of the housing 10 and the outer wall surface of the first transmission member 21 is provided with a first sliding groove 111, and the first rib 212 is inserted into the first sliding groove 111 in a manner of being slidable along the axial direction of the first sliding groove 111, so that the first transmission member 21 can only move in a linear direction and cannot rotate, and further, the second transmission member 22 and the first transmission member 21 can rotate relatively under the action of the driving assembly 50, and friction force is generated, so that the first transmission member 21 cannot rotate together with the second transmission member 22.
Specifically, in some embodiments of the present application, the inner wall surface of the first housing portion 11 is provided with a first slide groove 111. The first transmission member 21 includes a main body portion 211, the main body portion 211 is substantially in a cylindrical structure with two open ends, the outer wall surface of the main body portion 211 is provided with a first rib 212, and the first rib 212 is inserted into the first sliding groove 111 in a manner of being capable of sliding along the axial direction of the first sliding groove 111, wherein the axial direction of the first sliding groove 111 is consistent with the axial direction of the second transmission member 22, so that the first transmission member 21 is ensured to slide along the axial direction of the second transmission member 22. Wherein, in order to ensure the smooth running of the first transmission member 21, the first transmission member 21 is prevented from rotating or jamming during the linear motion, the number of the first ribs 212 is at least two, and at least two first ribs 212 are disposed at intervals along the outer peripheral surface of the main body 211.

In some embodiments of the present application, the second rib 31 may be disposed on an outer circumferential surface of an end of the trigger 30 facing the first transmission member 21, and the second rib 31 and an end surface of the end of the trigger 30 facing the first transmission member 21 are together abutted against the first transmission member 21, so as to drive the first transmission member 21 to slide along the axial direction of the second transmission member 22.
As shown in fig. 2 and 3, in some embodiments of the present application, the surface of the first rib 212 is concavely provided with a first groove, and the force feedback device 1 further includes a magnetic member 60 and a magnetic induction member 70, wherein the magnetic member 60 is disposed in the first groove, and the magnetic induction member 70 is disposed in the housing 10 and is used for detecting the position of the magnetic member 60.
The magnetic piece 60 is arranged in the first groove, the magnetic piece 60 can move together along with the movement of the first transmission piece 21, the position of the first transmission piece 21 can be determined by detecting the position of the magnetic piece 60 through the magnetic induction piece 70, so that the initial position of the first transmission piece 21 is accurately positioned, the trigger 30 is abutted with the first transmission piece 21 at any position, and force feedback is provided. Wherein the magnetic member 60 may comprise a magnet and the magnetic induction member 70 may comprise a hall sensor.
As shown in connection with fig. 2 and 3, in some embodiments of the present application, the driving assembly 50 includes a driving motor 51 and a driving gear 52, the driving gear 52 is drivingly connected with an output shaft of the driving motor 51, and the second driving member 22 includes a screw portion 221 and a gear portion 222 sequentially disposed in an axial direction, wherein the screw portion 221 is screw-driven with the first driving member 21, and the gear portion 222 is engaged with the driving gear 52.
Specifically, the screw portion 221 is disposed at an end of the second transmission member 22 facing the trigger 30, and the gear portion 222 is disposed at an end of the second transmission member 22 facing away from the trigger 30. The outer peripheral surface of the screw part 221 is provided with external threads, the inner peripheral surface of the main body part 211 is provided with internal threads, and the external threads and the internal threads are matched to realize the thread transmission of the main body part 211 and the screw part 221. When the driving motor 51 rotates, the transmission gear 52 rotates together with the output shaft of the driving motor 51, the gear portion 222 is meshed with the transmission gear 52 to drive the second transmission member 22 to rotate integrally, and the first rib 212 on the main body portion 211 is inserted into the first chute 111 due to the threaded transmission of the main body portion 211 and the screw portion 221, so as to drive the first transmission member 21 to move along the axial direction of the second transmission member 22, and the moving direction of the first transmission member 21 is determined according to the rotating direction of the output shaft of the driving motor 51.

By providing a bi-directional motor, the first transmission member 21 can be controlled to slide in a direction approaching the trigger 30, or the first transmission member 21 can be controlled to slide in a direction departing from the trigger 30, thereby positioning and adjusting the position of the first transmission member 21.
Wherein, most structures of the driving motor 51 are arranged outside the shell 10, and only the output shaft part is spliced in the shell 10 and is in driving connection with the transmission gear 52, thereby effectively reducing the volume of the shell 10. Meanwhile, the portion of the driving motor 51 provided outside the housing 10 is provided at the end where the trigger 30 is located, as illustrated in fig. 6, thereby reducing the overall volume of the force feedback device 1. In some embodiments of the present application, as shown in FIG. 7, the drive motor 51 may also be provided on the exterior of the housing 10 at an end remote from the trigger 30, thereby facilitating the attachment of the drive motor 51 to other components.
Since the bidirectional motor can switch the rotation direction of the output shaft at any time, the control of the movement direction of the first transmission member 21 can be switched at any time as needed. As shown in fig. 5, the trigger 30 abuts against the first transmission member 21, and at this time, the driving motor 51 provides driving force and moves the first transmission member 21 in a direction approaching the trigger 30, and at this time, the pressing trigger 30 is subjected to not only force feedback action of the elastic member 40 but also friction force between the first transmission member 21 and the second transmission member 22 and driving force of the driving assembly 50. If the bi-directional motor is controlled to rotate in the opposite direction and the first transmission member 21 is moved in a direction away from the trigger 30, as shown in fig. 6, the trigger 30 is spaced from the first transmission member 21, and the pressing trigger 30 is only subjected to the force feedback action of the elastic member 40. Therefore, the rotation direction of the bidirectional motor can be repeatedly switched, so that the trigger 30 is subjected to the action of force feedback with different degrees when being pressed, and the vibration effect is achieved.
In some embodiments of the present application, as shown in fig. 2 and 3, the elastic member 40 is a spring, and the second transmission member further includes an extension end 223, where the extension end 223, the screw portion 221 and the gear portion 222 are sequentially disposed along the axial direction, the diameter of the extension end 223 is smaller than the diameter of the screw portion 221, one end of the spring is abutted with the trigger 30, and the other end of the spring is sleeved outside the extension end 223 and abutted with the end of the screw portion 221.
Specifically, the inside of the trigger 30 is provided with a receiving cavity, one end of the spring is inserted into the receiving cavity and abuts against the inner wall of the end of the receiving cavity, and the other end of the spring is sleeved outside the extending end 223 and abuts against the end of the screw portion 221, so that the elastic member 40 can be ensured to be extruded in the process of pressing the trigger 30 towards the second transmission member 22, and force feedback is provided through the elastic member 40. Meanwhile, since the second transmission member 22 can rotate under the action of the driving assembly 50, in order to prevent the spring from rotating together with the second transmission member 22 and avoid failure or breakage of the spring, the other end of the spring is sleeved outside the extending end 223, and the second transmission member 22 can rotate relative to the other end of the spring.
The second aspect of the application also proposes a handle with a force feedback device 1 according to any of the embodiments described above. Since the handle has the same technical features as the force feedback device 1 of any of the above embodiments, the same technical effects can be achieved, and a detailed description thereof will be omitted.
The present application is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present application are intended to be included in the scope of the present application. Therefore, the protection scope of the application is subject to the protection scope of the claims.
