Description

Technical Field

[0001] This invention belongs to the field of electronic equipment technology, specifically designing a force feedback device and a handle. Background Technology

[0002] Currently, in order to improve the user experience, game device manufacturers are adding force feedback devices to game controllers to simulate the immersive feeling of specific game scenarios, such as drawing a bow and shooting an arrow, pulling the trigger of various guns, and other game operations with force feedback.

[0003] However, the force curves of existing force feedback devices are fixed, making it inconvenient to adjust them according to different game scenarios, which makes it difficult to provide users with a good gaming experience. Summary of the Invention

[0004] The objective of this invention is to at least solve the problem of inconvenient adjustment of the feedback force in force feedback devices. This objective is achieved through the following means:

[0005] A first aspect of the present invention provides a force feedback device, the force feedback device comprising:

[0006] case;

[0007] A transmission assembly is disposed inside the housing. The transmission assembly includes a first transmission member and a second transmission member. The first transmission member is sleeved on the outside of the second transmission member and is threadedly driven by the second transmission member.

[0008] A trigger, at least part of which is located inside the housing, with an elastic element between the trigger and the second transmission member, the trigger being capable of reciprocating along the axial direction of the second transmission member, and being able to compress the elastic element and abut against the first transmission member during the movement of the trigger toward the second transmission member;

[0009] A drive assembly, which is connected to the second transmission member and is used to drive the second transmission member to rotate.

[0010] According to the force feedback device of the present invention, since an elastic element is provided between the second transmission member and the trigger, the device is always subjected to the force feedback action of the elastic element during the process of pressing the trigger.

[0011] When the drive assembly does not provide driving force, and the trigger moves to abut against the first transmission member, and the trigger can drive the first transmission member to continue moving towards the second transmission member, due to the threaded transmission between the first and second transmission members, pressing the trigger is not only subject to the force feedback of the elastic member, but also to the frictional force between the first and second transmission members.

[0012] When the drive assembly provides driving force to the second transmission component, causing the first transmission component to move toward the trigger under the action of the second transmission component and come into contact with the trigger, pressing the trigger is not only subject to the force feedback of the elastic component, but also to the frictional force between the first and second transmission components, as well as the driving force of the drive assembly. This effectively adjusts the feedback force, thereby increasing the range of the feedback force and improving the user experience.

[0013] In addition, the force feedback device according to the present invention may also have the following additional technical features:

While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0042] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0043] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0044] For ease of description, in the context of this specification, when an element is referred to as being "on" another element, it can be directly on the other element or indirectly on the other element if one or more intermediate elements are inserted therebetween. Furthermore, in the context of this specification, when an element is referred to as being "connected," "joined," or "attached" to another element, it can be directly connected, joined, or attached to the other element or indirectly connected, joined, or attached to the other element if one or more intermediate elements are inserted therebetween. Additionally, when an element is referred to as being "engaged" to another element, it can be directly engaged or in contact with the other element, or indirectly engaged or in contact with the other element if one or more intermediate elements are inserted therebetween.

[0045] Spatial relative terms may also be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, then an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0046] To at least address the problem of inconvenient adjustment of the feedback force in force feedback devices, this application proposes a force feedback device and a handle incorporating it. The device allows for adjustment of the feedback force in multiple modes, thereby increasing the range of force values ​​and improving the user experience. This force feedback device can be used in various technical fields, such as medical, modeling, training, virtual assembly, robot control, games, entertainment, and VR, to provide feedback and enhance the user experience. For ease of description, the embodiments described in this application are exemplified only by the application of this force feedback device to a handle.

[0047] Combination Figures 1 to 3 As shown, in some embodiments of the present invention, the force feedback device 1 includes a housing 10, a transmission assembly 20, a trigger 30, and a drive assembly 50. The transmission assembly 20 is disposed inside the housing 10 and includes a first transmission member 21 and a second transmission member 22. The first transmission member 21 is sleeved on the outside of the second transmission member 22 and is threadedly driven by the second transmission member 22. At least part of the trigger 30 is disposed inside the housing 10. An elastic member 40 is provided between the trigger 30 and the second transmission member 22. The trigger 30 can reciprocate along the axial direction of the second transmission member 22, and can squeeze the elastic member 40 and abut against the first transmission member 21 during the movement of the trigger 30 toward the second transmission member 22. The drive assembly 50 is connected to the second transmission member 22 and is used to drive the second transmission member 22 to rotate.

[0048] Specifically, the housing 10 has an internal cavity where the transmission assembly 20, part of the trigger 30, and part of the drive assembly 50 can be housed. These components provide feedback force when the trigger 30 is pressed, through a transmission engagement. The housing 10 includes a detachably connected first housing portion 11 and a second housing portion 12, which together form the cavity, facilitating disassembly and assembly. Since the first transmission member 21 is sleeved outside the second transmission member 22 and threadedly driven by it, when the drive 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 it along its axial direction. This adjusts the distance between the first transmission member 21 and the trigger 30, thereby adjusting the form of the feedback force received by the trigger 30.

[0049] The first transmission member 21, under the action of the drive assembly 50 and the second transmission member 22, can reciprocate along the axial direction of the second transmission member 22, and has a first limit position, a second limit position, and an intermediate position between the first limit position and the second limit position. When the first transmission member 21 is in the first limit position, the first transmission member 21 is located away from the trigger 30 and cannot continue to move in the direction away from the trigger 30. When the first transmission member 21 is in the second limit position, the first transmission member 21 is located at the end of the second transmission member 22 close to the trigger 30 and is in close contact with the trigger 30. When the first transmission member 21 is in the intermediate position, the first transmission member 21 is spaced apart from or in close contact with the trigger 30 and can continue to move in the direction away from the trigger 30.

[0050] According to the force feedback device 1 of the present invention, since an elastic element 40 is provided between the second transmission member 22 and the trigger 30, the device is always subjected to the force feedback action of the elastic element 40 during the process of pressing the trigger 30.

[0051] like Figure 1 As shown, at this time, the drive assembly 50 does not provide driving force, the first transmission member 21 is in the first extreme position, the first transmission member 21 is spaced apart from the trigger 30, and during the process of pressing the trigger 30, it is only subjected to the force feedback of the elastic member 40, until the trigger 30 moves to the position shown. Figure 2 The position shown. If at this time, the drive assembly 50 still does not provide driving force, the trigger 30 is only subjected to the force feedback of the elastic element 40. If at this time, the drive assembly 50 provides driving force and causes the first transmission element 21 to tend to move towards the trigger 30, then the trigger 30 is not only subjected to the force feedback of the elastic element 40, but also to the driving force provided by the drive assembly 50.

[0052] When the drive assembly 50 does not provide 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 continue moving towards the second transmission member 22, due to the threaded transmission between the first transmission member 21 and the second transmission member 22, pressing the trigger 30 is not only subject to the force feedback of the elastic member 40, but also to the frictional force between the first transmission member 21 and the second transmission member 22.

[0053] like Figure 4 As shown, at this time, the first transmission member 21 is in the second extreme position, abutting against the trigger 30, and the trigger 30 can drive the first transmission member 21 to continue moving towards the second transmission member 22. If the drive 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 pressing of the trigger 30. There is friction between the threaded transmission of the first transmission member 21 and the second transmission member 22. Therefore, pressing the trigger 30 is not only affected by the force feedback of the elastic member 40, but also by the friction between the first transmission member 21 and the second transmission member 22. If the drive assembly 50 provides driving force at this time, pressing the trigger 30 is not only affected by the force feedback of the elastic member 40, but also by the friction between the first transmission member 21 and the second transmission member 22, as well as the driving force of the drive assembly 50.

[0054] like Figure 5 As shown, at this time, the first transmission member 21 is in the middle, abutting against the trigger 30, and the trigger 30 can drive the first transmission member 21 to continue moving towards the second transmission member 22. If the drive 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. There is friction between the threaded transmission of the first transmission member 21 and the second transmission member 22. Therefore, pressing the trigger 30 is not only affected by the force feedback of the elastic member 40, but also by the friction between the first transmission member 21 and the second transmission member 22. If the drive assembly 50 provides driving force at this time, pressing the trigger 30 is not only affected by the force feedback of the elastic member 40, but also by the friction between the first transmission member 21 and the second transmission member 22, as well as the driving force of the drive assembly 50.

[0055] like Figure 6 As shown, at this time, the first transmission component 21 is in the middle, and the first transmission component 21 is spaced apart from the trigger 30. The trigger 30 can travel a certain distance before driving the first transmission component 21 to continue moving towards the second transmission component 22. If, at this time, the drive assembly 50 does not provide driving force, the trigger 30 moves towards the first transmission component 21 during the pressing of the trigger 30. During this process, it is only subject to the force feedback of the elastic element 40. When the trigger 30 reaches the point of contact with the first transmission component 21, as... Figure 5 As shown, if the trigger 30 is pressed and the drive assembly 50 does not provide driving force, 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. There is friction between the threaded transmission of the first transmission member 21 and the second transmission member 22. Therefore, pressing the trigger 30 is not only subject to the force feedback of the elastic member 40, but also to the friction between the first transmission member 21 and the second transmission member 22. Figure 5 As shown, if the drive assembly 50 provides driving force at this time, the pressed trigger 30 is not only subject to the force feedback of the elastic element 40, but also to the frictional force between the first transmission element 21 and the second transmission element 22, as well as the driving force of the drive assembly 50.

[0056] According to the force feedback device 1 of this application, the feedback force can be effectively adjusted, thereby increasing the range of the feedback force value and improving the user experience.

[0057] Combination Figure 2 and Figure 3 As shown, in some embodiments of the present invention, 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 protruding 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. The first protruding rib 212 is inserted into the first sliding groove 111 in a manner that allows it to slide along the axial direction of the first sliding groove 111, thereby ensuring that the first transmission member 21 can only move in a straight line and cannot rotate. This ensures that under the action of the driving assembly 50, the second transmission member 22 and the first transmission member 21 rotate relative to each other and generate friction, without the first transmission member 21 rotating together with the second transmission member 22.

[0058] Specifically, in some embodiments of the present invention, the inner wall surface of the first housing portion 11 is provided with a first sliding groove 111. The first transmission member 21 includes a main body portion 211, which is generally a cylindrical structure with open ends. The outer wall surface of the main body portion 211 is provided with a first rib 212. The first rib 212 is inserted into the first sliding groove 111 in a manner that allows it to slide along the axial direction of the first sliding groove 111. The axial direction of the first sliding groove 111 is consistent with the axial direction of the second transmission member 22, thereby ensuring that the first transmission member 21 slides along the axial direction of the second transmission member 22. In order to ensure the smooth operation of the first transmission member 21 and prevent the first transmission member 21 from rotating or jamming during linear motion, the number of first ribs 212 is at least two, and at least two first ribs 212 are spaced apart along the outer peripheral surface of the main body portion 211.

[0059] Combination Figure 2 and Figure 3As shown, in some embodiments of the present invention, the trigger 30 has a second rib 31 at one end inside the housing 10. The second rib 31 is inserted into the first slide groove 111 in a manner that allows it to slide along the axial direction of the first slide groove 111, and the second rib 31 can abut against the first transmission member 21, thereby ensuring the smooth operation of the trigger 30 within the housing 10 and preventing the trigger 30 from rotating or jamming during linear movement. In some embodiments of the present invention, the second rib 31 can be provided on the outer peripheral surface of the end of the trigger 30 facing the first transmission member 21. The end face of the second rib 31 and the end face of the trigger 30 facing the first transmission member 21 abut against the first transmission member 21, thereby driving the first transmission member 21 to slide along the axial direction of the second transmission member 22.

[0060] Combination Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the surface of the first rib 212 is recessed with a first groove, and the force feedback device 1 further includes a magnetic element 60 and a magnetic induction element 70. The magnetic element 60 is disposed in the first groove, and the magnetic induction element 70 is disposed in the housing 10 and used to detect the position of the magnetic element 60.

[0061] A magnetic component 60 is disposed within the first groove. The magnetic component 60 moves in tandem with the movement of the first transmission component 21. By detecting the position of the magnetic component 60 using a magnetic induction component 70, the position of the first transmission component 21 can be determined, thereby accurately positioning the initial position of the first transmission component 21 and enabling the trigger 30 to abut against the first transmission component 21 at any position, providing force feedback. The magnetic component 60 may include a magnet, and the magnetic induction component 70 may include a Hall sensor.

[0062] Combination Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the drive assembly 50 includes a drive motor 51 and a transmission gear 52. The transmission gear 52 is driven to the output shaft of the drive motor 51. The second transmission member 22 includes a screw portion 221 and a gear portion 222 arranged sequentially along the axial direction. The screw portion 221 is threaded to the first transmission member 21, and the gear portion 222 meshes with the transmission gear 52.

[0063] Specifically, the screw portion 221 is located at the end of the second transmission member 22 facing the trigger 30, and the gear portion 222 is located at the end of the second transmission member 22 away from the trigger 30. The outer circumferential surface of the screw portion 221 is provided with an external thread, and the inner circumferential surface of the main body portion 211 is provided with an internal thread. The external thread and the internal thread cooperate to realize the threaded transmission between the main body portion 211 and the screw portion 221. When the drive motor 51 rotates, the transmission gear 52 rotates together with the output shaft of the drive motor 51. The gear portion 222 meshes with the transmission gear 52, thereby driving the second transmission member 22 to rotate as a whole. Due to the threaded transmission between the main body portion 211 and the screw portion 221, and the first protrusion 212 on the main body portion 211 being inserted into the first sliding groove 111, the first transmission member 21 is driven to move along the axial direction of the second transmission member 22. The direction of movement of the first transmission member 21 is determined according to the rotation direction of the output shaft of the drive motor 51.

[0064] Combination Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the drive motor 51 is a bidirectional motor. By providing a bidirectional motor, the first transmission member 21 can be controlled to slide in a direction close to the trigger 30, or the first transmission member 21 can be controlled to slide in a direction away from the trigger 30, thereby positioning and adjusting the position of the first transmission member 21.

[0065] Most of the drive motor 51 is located outside the housing 10, with only the output shaft inserted inside the housing 10 and driven by the transmission gear 52, thus effectively reducing the size of the housing 10. Meanwhile, the portion of the drive motor 51 located outside the housing 10 is situated at the end where the trigger 30 is located, such as... Figure 6 This reduces the overall size of the force feedback device 1. In some embodiments of the present invention, such as... Figure 7 As shown, the drive motor 51 can also be located outside the housing 10 at the end away from the trigger 30, which makes it easier to fix the drive motor 51 to other components.

[0066] Because 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 component 21 can be switched as needed. Figure 5 As shown, the trigger 30 abuts against the first transmission member 21. At this time, the drive motor 51 provides driving force and moves the first transmission member 21 towards the trigger 30. Pressing the trigger 30 at this time is not only subject to the force feedback from the elastic member 40, but also to the frictional force between the first transmission member 21 and the second transmission member 22, as well as the driving force from the drive assembly 50. If the bidirectional motor is controlled to rotate in the opposite direction at this time, and the first transmission member 21 moves away from the trigger 30, as... Figure 6As shown, the trigger 30 and the first transmission component 21 are spaced apart at this time, and pressing the trigger 30 only receives force feedback from the elastic component 40. Therefore, by repeatedly switching the rotation direction of the bidirectional motor, different degrees of force feedback can be applied to pressing the trigger 30, thereby achieving a vibration effect.

[0067] Combination Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the elastic element 40 is a spring, and the second transmission element further includes an extension end 223. The extension end 223, the screw portion 221 and the gear portion 222 are arranged sequentially 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 abuts against the trigger 30, and the other end of the spring is sleeved on the outside of the extension end 223 and abuts against the end of the screw portion 221.

[0068] Specifically, the trigger 30 has an internal receiving cavity. One end of the spring is inserted into the receiving cavity and abuts against the inner wall of the cavity. The other end of the spring is sleeved on the outside of the protruding end 223 and abuts against the end of the screw portion 221. This ensures that the elastic element 40 is compressed when the trigger 30 is pressed towards the second transmission member 22, and force feedback is provided through the elastic element 40. At the same time, since the second transmission member 22 can rotate under the action of the drive assembly 50, in order to prevent the spring from rotating with the second transmission member 22 and avoid spring failure or breakage, the other end of the spring is sleeved on the outside of the protruding end 223, ensuring that the second transmission member 22 can rotate relative to the other end of the spring.

[0069] A second aspect of the invention also provides a handle having the force feedback device 1 in any of the above embodiments. Since this handle has the same technical features as the force feedback device 1 in any of the above embodiments and can achieve the same technical effect, it will not be described in detail here.

[0070] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
