Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to a force feedback device and an electronic device. Background Technology

[0002] With the development of technology, electronic devices have become increasingly sophisticated in function. They have become indispensable tools in people's daily lives, including travel, entertainment, and communication. In related technologies, to enhance the tactile experience of operating electronic devices, vibration mechanisms are incorporated. These mechanisms vibrate the device, providing tactile feedback. However, these vibration mechanisms can only drive the overall vibration of the electronic device and cannot provide precise tactile feedback for trigger presses.

[0003] Therefore, the aforementioned problems prevent the vibration mechanism in the relevant technology from providing accurate tactile feedback to the trigger pressed by the user. Summary of the Invention

[0004] This application aims to provide a force feedback device and electronic device that at least solves the technical problem in the related art that the vibration mechanism cannot provide accurate tactile feedback to the trigger pressed by the user.

[0005] In a first aspect, embodiments of this application propose a force feedback device, comprising:

[0006] Base;

[0007] The trigger is rotatably connected to the base;

[0008] The first transmission assembly is connected to the trigger drive;

[0009] The second transmission assembly includes a first gear, a transmission gear, a gear ring, and a rotating bracket. The transmission gear meshes between the first gear and the gear ring. The gear ring is fixed to the base. The rotating bracket is connected to the transmission gear and can rotate relative to the first gear and the gear ring. One of the rotating bracket and the first gear is the first transmission end of the second transmission assembly, and the other is the second transmission end of the second transmission assembly. The first transmission end is connected to the first transmission assembly in a transmission manner.

[0010] The drive component is connected to the second transmission end and is capable of driving the second transmission end to rotate.

[0011] When the trigger rotates relative to the base, the trigger can drive the first transmission end to rotate through the first transmission assembly, and the drive assembly can drive the second transmission end to rotate in order to block or assist the rotation of the first transmission end.

[0012] Secondly, embodiments of this application provide an electronic device including any of the force feedback devices provided in the first aspect.

[0013] In the embodiments of this application, by setting a first transmission component and a second transmission component to be connected between the trigger and the drive component, the first transmission component and the second transmission component can transmit power between the trigger and the drive component; by setting the drive component to drive the second transmission end to rotate, thereby blocking or assisting the rotation of the first transmission end, the drive component can assist or hinder the rotation of the trigger relative to the base through the first transmission component and the second transmission component, so that the trigger can realize tactile feedback such as damping, force release, vibration, and rebound. This tactile feedback is accurately fed back to the user through the trigger, improving the realism and accuracy of the tactile feedback.

[0030] The following is combined with Figures 1 to 10 Describes a force feedback device 100 according to an embodiment of this application.

[0031] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4A force feedback device 100 includes a base 1, a trigger 2, a first transmission assembly 4, a second transmission assembly 5, and a drive assembly 3. The trigger 2 is rotatably connected to the base 1. The first transmission assembly 4 is drive-connected to the trigger 2. The second transmission assembly 5 includes a first gear 53, a transmission gear 54, a gear ring 52, and a rotating bracket 51. The transmission gear 54 meshes between the first gear 53 and the gear ring 52. The gear ring 52 is fixed to the base 1. The rotating bracket 51 is connected to the transmission gear 54 and can rotate relative to the first gear 53 and the gear ring 52. One of the rotating bracket 51 and the first gear 53 is the first transmission end of the second transmission assembly 5, and the other is the second transmission end of the second transmission assembly 5. The first transmission end is drive-connected to the first transmission assembly 4. The drive assembly 3 is drive-connected to the second transmission end and can drive the second transmission end to rotate. When the trigger 2 rotates relative to the base 1, the trigger 2 can drive the first transmission end to rotate through the first transmission assembly 4. The drive assembly 3 can block or assist the first transmission end to rotate by driving the second transmission end to rotate.

[0032] The force feedback device 100 provided in this application can be installed in an electronic device, such as a gamepad, remote control, etc., for interacting with other electronic devices. It can also be a mobile phone, tablet computer, laptop computer, PDA, in-vehicle electronic device, augmented reality (AR) / virtual reality (VR) device, video game console, etc. This application does not limit the specific type of electronic device. For ease of description, the following description uses the application of the force feedback device 100 to a gamepad as an example.

[0033] The base 1 can provide a mounting base for the trigger 2 and the drive assembly 3, and can also provide a receiving space for the first transmission assembly 4 and / or the second transmission assembly 5 to accommodate at least a portion of the first transmission assembly 4 and / or at least a portion of the second transmission assembly 5. For example, the first gear 53, the transmission gear 54, the gear ring 52, and the rotating bracket 51 can be housed together in the base 1.

[0034] At least a portion of the trigger 2 is exposed outside the handle housing, allowing the user to touch and apply force to the trigger 2. The trigger 2 is rotatably connected to the base 1, and the user can apply force to the trigger 2 and push it to rotate relative to the base 1, thereby changing the rotation of the trigger 2 relative to the base 1 between a first position and a second position.

[0035] The trigger 2, the first transmission assembly 4, the second transmission assembly 5, and the drive assembly 3 are connected in sequence. When the trigger 2 rotates in the first position and the second position, the trigger 2 can drive the first transmission assembly 4 to move, and the first transmission assembly 4 drives the second transmission assembly 5 to move. The drive assembly 3 can also output power to the second transmission assembly 5, causing the second transmission assembly 5 to move, and the second transmission assembly 5 drives the first transmission assembly 4 to move. The first transmission assembly 4 drives or restricts the trigger 2 to rotate in the first position and the second position.

[0036] The first transmission assembly 4 may include one or more of a transmission rod, gear, worm gear, transmission belt, and chain to transmit power from the trigger 2 to the second transmission assembly 5, or to transmit power from the second transmission assembly 5 to the trigger 2.

[0037] The transmission gear 54 can revolve around the first gear 53, and the transmission gear 54 also rotates on its own axis. In the embodiments provided in this application, the second transmission assembly 5 has a first transmission end and a second transmission end, and the second transmission assembly 5 can provide at least the following two transmission connection methods:

[0038] In the first configuration, the rotating bracket 51 serves as the first transmission end, and the first gear 53 as the second transmission end. The rotating bracket 51 is connected to the first transmission assembly 4, and the first gear 53 is connected to the drive assembly 3. When the drive assembly 3 outputs power to the second transmission end, the drive shaft of the drive assembly 3 drives the first gear 53 to rotate. The first gear 53 drives the transmission gear 54, which meshes with it, to rotate around the central axis of the first gear 53. Since the gear ring 52 is fixed to the base 1, the gear ring 52 does not rotate with the transmission gear 54. The transmission gear 54 drives the rotating bracket 51 to rotate, and the rotating bracket 51 outputs power to the first transmission assembly 4. The direction of force transmission when the first transmission assembly 4 outputs power to the first transmission end is opposite to the direction of force transmission when the drive assembly 3 outputs power to the second transmission end; this will not be elaborated further here.

[0039] In the second configuration, the first gear 53 is the first transmission end, and the rotating bracket 51 is the second transmission end. The first gear 53 is connected to the first transmission assembly 4, and the rotating bracket 51 is connected to the drive assembly 3. When the drive assembly 3 outputs power to the second transmission end, the drive shaft of the drive assembly 3 drives the rotating bracket 51 to rotate. The rotating bracket 51 drives the transmission gear 54 connected to it to rotate around the central axis of the first gear 53. Since the gear ring 52 is fixed to the base 1, the gear ring 52 does not rotate with the transmission gear 54. The transmission gear 54 drives the first gear 53 to rotate, and the first gear 53 outputs power to the drive assembly 3. The direction of force transmission when the first transmission assembly 4 outputs power to the first transmission end is opposite to the direction of force transmission when the drive assembly 3 outputs power to the second transmission end, which will not be elaborated further here.

[0040] The drive assembly 3 may include a rotary motor, linear motor, or other driving components. The drive assembly 3 can directly or indirectly output power in both directions to the second transmission assembly 5. When the power output by the drive assembly 3 is in the same direction as the trigger 2 driving the second transmission end to rotate via the first transmission assembly 4, the power output by the drive assembly 3 assists the second transmission end in rotating. When the power output by the drive assembly 3 is in the opposite direction to the trigger 2 driving the second transmission end to rotate via the first transmission assembly 4, the power output by the drive assembly 3 opposes the rotation of the second transmission end. By adjusting parameters such as the direction of the output power, the magnitude of the torque, and the duration of the power output by the drive assembly 3, tactile feedback such as pressing damping, force release, vibration, and rebound can be achieved.

[0041] In the force feedback device 100 provided in this embodiment, a first transmission component 4 and a second transmission component 5 are connected to the trigger 2 and the drive component 3, allowing power to be transmitted between the trigger 2 and the drive component 3. A transmission gear 54 is engaged between a first gear 53 and a gear ring 52, and a rotating bracket 51 is connected to the transmission gear 54. The transmission ratio of the second transmission component 5 can be adjusted by adjusting the number of teeth of the transmission gear 54, the first gear 53, and the gear ring 52, enabling the force feedback device 100 to achieve force feedback responses of different precisions. The drive component 3 can drive the second transmission end to rotate, thereby blocking or assisting the rotation of the first transmission end. The drive component 3 can assist or hinder the rotation of the trigger 2 relative to the base 1 through the first transmission component 4 and the second transmission component 5, enabling the trigger 2 to achieve tactile feedback such as damping, force release, vibration, and rebound. This tactile feedback is accurately transmitted to the user through the trigger 2, improving the realism and accuracy of the tactile feedback.

[0042] With the gear ring 52 fixed, the first gear 53 as the power input end, and the rotating bracket 51 as the power output end, the transmission ratio of the second transmission assembly 5 is greater than 1, and the rotational speed of the power input end of the second transmission assembly 5 is greater than the rotational speed of the power output end. The second transmission assembly 5 then performs a deceleration and torque increase motion. With the gear ring 52 fixed, the rotating bracket 51 as the power input end, and the first gear 53 as the power output end, the transmission ratio of the second transmission assembly 5 is less than 1, and the rotational speed of the power input end of the second transmission assembly 5 is less than the rotational speed of the power output end. The second transmission assembly 5 then performs an acceleration and torque decrease motion. Therefore, those skilled in the art can determine whether the drive assembly 3 is connected to the rotating bracket 51 or the gear ring 52 based on the requirements for increasing or decreasing the output rotational speed of the drive assembly 3 and the requirements for increasing or decreasing the output torque of the drive assembly 3.

[0043] In some embodiments, the first transmission end is a rotating bracket 51, the second transmission end is a first gear 53, and the first transmission assembly 4, the rotating bracket 51, the first gear 53 and the drive assembly 3 are arranged sequentially along the first direction X.

[0044] Since the rotating bracket 51 is connected to the first transmission assembly 4 and the first gear 53 is connected to the drive assembly 3, the torque input by the drive mechanism through the first gear 53 can be amplified through the second transmission assembly 5. This increases the torque that the drive assembly 3 can exert on the trigger 2 through the first transmission assembly 4 and the second transmission assembly 5 while keeping the maximum output torque of the drive assembly 3 constant.

[0045] Please refer to the following: Figure 5 and Figure 6 , Figure 5 This is a three-dimensional structural diagram of the force feedback device 100 when the trigger 2 is in the first position. Figure 6 This is a three-dimensional structural diagram of the force feedback device 100 when the trigger 2 is in the second position. For example, the first position is when the trigger 2 is in the initial position relative to the base 1, and the second position is when the trigger 2 is in the pressed position relative to the base 1.

[0046] For example, such as Figure 2 and Figure 5 As shown, the user presses trigger 2, causing trigger 2 to move along the path shown in the figure. Figure 5 The dashed arrow indicates that the trigger 2 and base 1 rotate from the first position to the second position. Figure 2 As shown, axis L1 rotates, and under the drive of trigger 2, rotating bracket 51 rotates around... Figure 2 The axis L2 shown rotates, and the rotating bracket 51 drives the transmission gear 54 to rotate while simultaneously revolving around the first gear 53. The transmission gear 54 inputs a driving force to the first gear 53, causing it to rotate in the first circumferential direction. When the drive assembly 3 outputs a driving force to the first gear 53 to rotate in the first circumferential direction, the drive assembly 3 can assist the first gear 53 in rotating in the first circumferential direction, allowing the user to experience tactile feedback of effortless triggering 2. The first and second circumferential directions are opposite. When the drive assembly 3 outputs a driving force to the first gear 53 to rotate in the second circumferential direction, the drive assembly 3 can hinder the first gear 53 from rotating in the first circumferential direction, allowing the user to experience tactile feedback of increased resistance, i.e., more effort required to press the trigger 2.

[0047] For example, such as Figure 6As shown, the user presses the trigger 2, which is in the second position. When the drive assembly 3 outputs a driving force to the first gear 53 to rotate in the second circumferential direction, the drive assembly 3 drives the first gear 53 to rotate in the second circumferential direction. The first gear 53 drives the transmission gear 54 to rotate while revolving around the first gear 53. The transmission gear 54 drives the rotating bracket 51 to rotate. The rotating bracket 51 outputs power to the first transmission assembly 4, which can drive the trigger 2 to rotate from the second position to the first position, so that the user feels the tactile feedback of the trigger 2 rebounding, that is, the trigger 2 returns to the initial position.

[0048] For example, when a user lightly touches the trigger 2, the drive assembly 3 outputs a driving force to the first gear 53 to reciprocate along the first circumferential direction and the second circumferential direction. The drive assembly 3 drives the first gear 53 to reciprocate along the first circumferential direction and the second circumferential direction. The first gear 53 drives the transmission gear 54 to rotate while revolving around the first gear 53. The transmission gear 54 drives the rotating bracket 51 to rotate. The rotating bracket 51 outputs power to the first transmission assembly 4 to reciprocate along the first circumferential direction and the second circumferential direction. The first transmission assembly 4 can drive the trigger 2 to reciprocate between the first position and the second position, so that the user can feel the tactile feedback of the trigger 2 vibrating.

[0049] In the embodiments provided in this application, the first transmission component 4, the rotating bracket 51, the first gear 53 and the drive component 3 are arranged sequentially along the first direction X. When the trigger 2 moves or the drive mechanism drives, the rotating bracket 51 and the first gear 53 rotate, and the transmission gear 54 rotates around the first gear 53 at the same time, so that the first transmission component 4 does not move in the first direction X, and the power transmission can be realized. This eliminates the need to reserve a moving space for the second transmission component 5 in the first direction X, and reduces the length of the force feedback device 100 in the first direction X.

[0050] Please see Figure 7 and Figure 8 In some embodiments, the base 1 has a first opening 12 and a second opening 13 arranged along a first direction X, the second transmission assembly 5 is disposed in the base 1, a portion of the rotating bracket 51 extends out of the base 1 through the first opening 12 and is connected to the first transmission assembly 4, and a portion of the drive assembly 3 extends into the base 1 through the second opening 13 and is connected to the first gear 53.

[0051] The first transmission assembly 4 can be disposed on one side of the base 1 along the first direction X, and the drive assembly 3 can be disposed on the other side of the base 1 along the first direction X. The base 1 not only provides a receiving space for housing the gear ring 52, the first gear 53, and the transmission gear 54, but also confines the lubricant used for lubricating the gear ring 52, the first gear 53, and the transmission gear 54 within the base 1, and also provides a mounting base for the gear ring 52, the rotating bracket 51, and the drive assembly 3.

[0052] By placing the gear ring 52, the first gear 53, and the transmission gear 54 in the base 1, impurities and other contaminants are prevented from entering the base 1 and interfering with the mutual movement of the gear ring 52, the first gear 53, and the transmission gear 54.

[0053] In some embodiments, the base 1 includes a first cover 14 and a second cover 15 that fit together, a first opening 12 is disposed on the first cover 14, a second opening 13 is disposed on the second cover 15, and a toothed ring 52 is fixed to the first cover 14 and / or the second cover 15.

[0054] The first cover 14 and the second cover 15 fit together, defining a receiving space. A gear ring 52 is fixed to the first cover 14 and / or the second cover 15, so that when the transmission gear 54 rotates, the gear ring 52 fixed to the first cover 14 and / or the second cover 15 does not rotate. Figure 8 In the embodiment shown, the toothed ring 52 is fixed to the second cover 15, and the toothed ring 52 and the second cover 15 are integrally formed to increase the connection stability of the toothed ring 52 and the second cover 15.

[0055] In some embodiments, the toothed ring 52 is fixed to the second cover 15, the first cover 14 includes a cover plate 141 and a side plate 142, the side plate 142 is disposed on the cover plate 141 and is disposed around the toothed ring 52, and the second cover 15 is disposed on the side plate 142.

[0056] The gear ring 52 has an internal tooth surface that meshes with the transmission gear 54, and the outer surface of the gear ring 52 is positioned opposite to the side plate 142. During assembly, the first gear 53, the transmission gear 54, the rotating bracket 51, and the gear ring 52 on the second cover 15 can be assembled first, and then the first cover 14 can be placed on the second cover 15, so that part of the rotating bracket 51 extends out of the first opening 12.

[0057] By setting the side plate 142 around the gear ring 52, the side plate 142 can protect the gear ring 52, reduce or avoid damage to the gear ring 52 by external forces, and improve the stability of the movement of the second transmission component 5.

[0058] In some embodiments, the rotating bracket 51 includes a mounting plate 541, a first connecting rod 542 and a second connecting rod 543. The first connecting rod 542 and the second connecting rod 543 are connected to both sides of the mounting plate 541 along the first direction X. The first connecting rod 542 extends out of the base 1 and is connected to the first transmission assembly 4. The second connecting rod 543 is connected to the transmission gear 54.

[0059] By providing a first connecting rod 542 and a second connecting rod 543 on the mounting plate 541, power can be transmitted between the second gear 42 and the transmission gear 54 by rotating the bracket 51.

[0060] In some embodiments, there are multiple transmission gears 54, which are arranged around the first gear 53, and the rotating bracket 51 is connected to the multiple transmission gears 54 respectively.

[0061] When there are multiple transmission gears 54, there are also multiple second connecting rods 543, with each second connecting rod 543 corresponding to one of the multiple transmission gears 54. The more transmission gears 54 there are, the greater the load that the second transmission assembly 5 can bear. Multiple transmission gears 54 can share the load, thereby reducing the force between each transmission gear 54 and the second connecting rod 543, and reducing the size of the transmission gears 54.

[0062] To balance the radial force at each meshing point of the transmission gears 54 and the centrifugal force generated by the revolution of the transmission gears 54, multiple transmission gears 54 can be evenly spaced around the first gear 53, increasing the smoothness of the rotation and revolution of the transmission gears 54. Figure 8 In the embodiment shown, there are three transmission gears 54, which are evenly arranged around the first gear 53. The first connecting rod 542 is coaxially arranged with the first gear 53, and the projections of the three second connecting rods 543 on the mounting plate 541 are arranged around the projection of the first connecting rod 542 on the mounting plate 541.

[0063] Please see Figure 9 In some embodiments, to facilitate user pressing of the trigger 2, the travel distance of the trigger 2 from the first position to the second position is relatively short. This means that when the trigger 2 rotates from the first position to the second position, the travel distance of the transmission gear 54 around the first gear 53 is less than the circumference of the first gear 53. That is, during the rotation of the trigger 2 from the first position to the second position, the transmission gear 54 does not need to revolve a full circle around the first gear 53. Therefore, in some embodiments, the gear ring 52 includes multiple arc-shaped racks 521 and limiting members 522 disposed at both ends of the arc-shaped racks 521. The multiple arc-shaped racks 521 are arranged sequentially and spaced apart around the first gear 53, and the multiple transmission gears 54 mesh with the multiple arc-shaped racks 521 one by one.

[0064] The limiting member 522 can be a protrusion of the relative arc-shaped member along the radial direction of the gear ring 52 towards the first gear 53. The two limiting members 522 located between the two arc-shaped racks 521 can be a single piece, and the arc-shaped racks 521 and the limiting members 522 are alternately arranged around the first gear 53.

[0065] The limiting member 522 can limit the revolution stroke of each transmission gear 54 and ensure that the length of the corresponding meshing arc rack 521 of the transmission gear 54 is consistent, thereby limiting the revolution stroke of the transmission gear 54 and limiting the angle of rotation of the trigger 2 relative to the base 1.

[0066] Optionally, when the trigger 2 is in the first position relative to the base 1, each transmission gear 54 contacts the limiting member 522 located at one end of the arc-shaped rack 521; when the trigger 2 is in the second position relative to the base 1, each transmission gear 54 contacts the limiting member 522 located at the other end of the arc-shaped rack 521. By providing the limiting member 522, the trigger 2 can be prevented from rotating relative to the base 1 beyond the first or second position. The arc-shaped rack 521 can have the same length.

[0067] Please refer to the following: Figure 8 and Figure 10 In some embodiments, the second transmission assembly 5 further includes a bearing 55, which is sleeved between the rotating bracket 51 and the base 1.

[0068] The bearing 55, fitted between the rotating bracket 51 and the base 1, can reduce the friction between the rotating bracket 51 and the base 1. Optionally, the bearing 55 is fitted between the first connecting rod 542 and the first cover 14. A clearance recess 145 may be provided on the cover plate 141 of the first cover 14. The bearing 55 can be placed in the clearance recess 145. The clearance recess 145 can limit the bearing 55 and at the same time accommodate at least part of the bearing 55, improving the assembly compactness of the second transmission assembly 5 and the base 1.

[0069] In some embodiments, the first transmission assembly 4 includes a swing arm 41 and a second gear 42. One end of the swing arm 41 is rotatably connected to the trigger 2, and the trigger 2 can drive the swing arm 41 to rotate relative to the base 1. The second gear 42 is connected to the rotating bracket 51 and meshes with the swing arm 41. The second gear 42, the second transmission assembly 5, and the drive assembly 3 are sequentially connected along the first direction X. The second transmission assembly 5 and the trigger 2 are spaced apart along the second direction Y. The first direction X and the second direction Y are intersected.

[0070] One end of the swing arm 41 and the trigger 2 can be integrally formed. When the trigger 2 rotates at a certain angular velocity, the swing arm 41 can rotate together at the same angular velocity. The other end of the swing arm 41 has meshing teeth that mesh with the second gear 42. When the swing arm 41 rotates, it can drive the second gear 42 to rotate. The rotational force generated by the rotation of the second gear 42 is input to the first rotating end to drive the second rotating end to rotate.

[0071] In this embodiment, by setting the swing arm 41 and the second gear 42, the rotation of the trigger 2 can be transmitted to the second transmission assembly 5. By setting the number of teeth of the second transmission assembly 5, the transmission ratio between the first rotating end and the second rotating end can be adjusted, improving the precision of the force feedback of the drive assembly 3 to the rotation of the trigger 2 through the first transmission assembly 4 and the second transmission assembly 5. The second transmission assembly 5 is set at a distance from the trigger 2 along the second direction Y to reduce the length of the force feedback device 100 in the first direction X.

[0072] Optionally, the trigger 2 rotates between a first position and a second position around a first axis L. The trigger 2 drives the swing arm 41 to rotate and translate within a reference plane around the first axis L. The first axis L extends along a first direction X. The second gear 42, the rotating bracket 51, the gear ring 52, and the first gear ring 52 extend along... Figure 2 The axis L2 shown is coaxially arranged. The first direction X and the second direction Y are perpendicularly arranged, and this reference plane can be arranged with the base 1 along the first direction X.

[0073] In some embodiments, the force feedback device 100 further includes a detection mechanism 6 and a control mechanism. The detection mechanism 6 includes a first sensor 61 and a second sensor 62. One of the first sensor 61 and the second sensor 62 is disposed on the first transmission assembly 4, and the other is disposed on the base 1. When the trigger 2 rotates relative to the base 1 between a first position and a second position, the first sensor 61 moves away from or closer to the second sensor 62. The first sensor 61 can generate relative position information of the first sensor 61 and the second sensor 62. The control mechanism is electrically connected to the drive assembly 3 and the first sensor 61, respectively. The control mechanism can control the drive assembly 3 to drive the second transmission end to rotate according to the relative position information.

[0074] A first sensor 61 and a second sensor 62 are provided so that the distance between them can be detected, which is equivalent to obtaining the relative positional relationship between the trigger 2 and the base 1. One of the first sensor 61 and the second sensor 62 can be a magnetic element, and the other can be a Hall element.

[0075] The relative position information can be an analog signal or a digital signal. The control mechanism includes a control chip, and the detection mechanism 6 can be electrically connected to the control chip to send the detected analog or digital signal to the control chip. The control chip can generate a control signal for the drive component 3 based on the analog or digital signal. The drive component 3 outputs power in different directions and magnitudes according to the control signal, thereby enabling the drive component 3 to output power in different directions and magnitudes according to the different relative positions of the trigger 2 and the base 1.

[0076] Since different specifications of electronic devices require adaptation to triggers 2 with different shapes, the first sensor 61 is mounted on the swing arm 41 to facilitate the force feedback device 100 in replacing triggers 2 of different specifications. Because the trigger 2 needs to be exposed outside the housing of the electronic device and bear the thrust applied by the user, the swing arm 41 has better stability than the trigger 2. By mounting the first sensor 61 on the swing arm 41, the stability of the first sensor 61 is improved.

[0077] In some embodiments, the force feedback device 100 further includes a rotating shaft 71 and a return spring 73. The trigger 2, the base 1 and the return spring 73 are all sleeved on the rotating shaft 71, and the return spring 73 abuts between the base 1 and the trigger 2.

[0078] As the user applies force to press the trigger 2 to rotate relative to the base 1, the return spring 73 deforms under the action of the base 1 and the trigger 2. When the user releases the trigger 2, the elastic restoring force of the return spring 73 drives the relative rotation of the base 1 and the trigger 2 to return to its original position.

[0079] For example, the first position is the initial position of trigger 2 relative to base 1, and the second position is the pressed position of trigger 2 relative to base 1. When the user presses trigger 2, trigger 2 rotates from the first position to the second position, causing deformation of the return spring 73 due to the compression of trigger 2 and base 1. When the user releases trigger 2, the elastic restoring force of return spring 73 drives base 1 and trigger 2 to rotate from the second position to the first position.

[0080] By setting the trigger 2, base 1 and return spring 73 to be sleeved on the rotating shaft 71, it is ensured that the trigger 2 and base 1 can rotate relative to each other around the axial direction of the rotating shaft 71; by setting the return spring 73 to abut between the base 1 and the trigger 2, the trigger 2 can automatically return from the first position to the second position, or automatically return from the second position to the first position, when there is no user pressing.

[0081] In some embodiments, the trigger 2 includes a main body 22 and a first rotating part 21 connected together. The first rotating part 21, which is spaced apart, is sleeved on the rotating shaft 71. The base 1 includes a side plate 142 and a second rotating part 144 connected together. The second rotating part 144, which is spaced apart, is sleeved on the rotating shaft 71. The return spring 73 abuts between the main body 22 and the side plate 142.

[0082] During the rotation of the first rotating part 21 and the second rotating part 144 around the rotating shaft 71, the main body 22 and the side plate 142 move closer together, so that the return spring 73, which abuts against the main body 22 and the side plate 142, can be compressed by the main body 22 and the side plate 142.

[0083] The first rotating part 21 and the second rotating part 144 may have through holes, and the rotating shaft 71 can be inserted into the through holes along the first direction X. The first cover 14 of the base 1 includes a side plate 142, a cover plate 141 and a connecting plate arranged at intervals along the first direction X, the side plate 142 connects the cover plate 141 and the connecting plate, and the areas with through holes on the cover plate 141 and the connecting plate are reused as the spaced second rotating parts 144.

[0084] In some embodiments, the base 1 includes a protrusion that protrudes away from the drive assembly 3 relative to the first cover 14. The protrusion is disposed opposite to the swing arm 41. A first sensor 61 is disposed on the side of the swing arm 41 near the protrusion, and a second sensor 62 is disposed on the protrusion. By disposing the second sensor 62 on the protrusion, the mounting base can avoid movement of the swing arm 41. Optionally, the mounting base has a first surface, and the protrusion protrudes relative to this first surface. The swing arm 41 can rotate within a reference plane containing the first surface.

[0085] In some embodiments, the force feedback device 100 has at least one of a first operating mode, a second operating mode, and a third operating mode.

[0086] When the force feedback device 100 is in the first working mode, the drive assembly 3 drives the second transmission end to rotate, so that the trigger 2 reciprocates between the first position and the second position relative to the base 1.

[0087] When the force feedback device 100 is in the second working mode and the trigger 2 rotates between the first position and the second position relative to the base 1, the trigger 2 drives the first transmission end to rotate along the first circumferential direction through the first transmission component 4, and the drive component 3 drives the second transmission end to rotate along the first circumferential direction.

[0088] When the force feedback device 100 is in the third working mode and the trigger 2 rotates between the first position and the second position relative to the base 1, the trigger 2 drives the first transmission end to rotate along the first circumferential direction through the first transmission component 4, and the drive component 3 drives the second transmission end to rotate along the second circumferential direction.

[0089] The first and second circumferential directions are opposite.

[0090] The first working mode can be vibration mode. The drive component 3 drives the second transmission end to reciprocate in the counterclockwise and clockwise directions. After being transmitted through the first transmission component 4 and the second transmission component 5, the trigger 2 reciprocates between the first position and the second position relative to the base 1, and the user feels the vibration of the trigger 2.

[0091] The second working mode can be a force-relieving mode. During the process of the user pressing the trigger 2 to rotate, the second transmission end rotates along the first circumference, and the drive component 3 drives the second transmission end to rotate along the first circumference, so that the user feels the force being released when pressing the trigger 2.

[0092] The second working mode can be a rebound mode. After the user presses and releases the trigger 2, the drive component 3 drives the second transmission end to rotate along the first or second circumferential direction. Under the action of the first transmission component 4, the trigger 2 is positioned relative to the base 1, and the user feels the trigger 2 rebound to the initial position.

[0093] The second operating mode can be a damped mode. As the user presses the trigger 2 to rotate, the second transmission end rotates along the first circumference, and the drive assembly 3 drives the second transmission end to rotate along the second circumference, requiring the user to apply a greater force to the trigger.

[0094] The force feedback device 100 may also have an initial wear function. When the force feedback device 100 is first powered on, the drive assembly 3 drives the second transmission end to rotate so that the trigger 2 is in a preset initial position relative to the base 1.

[0095] This application also discloses an electronic device including the force feedback device 100 from any of the above embodiments. Applying the force feedback device 100 from any of the above embodiments to this electronic device allows for tactile feedback such as damping, force release, vibration, and rebound via the trigger 2. This tactile feedback is accurately transmitted to the user via the trigger 2, improving the realism and accuracy of the tactile feedback.
