Description

Technical Field

[0001] The present invention relates to the technical field of interactive terminals, and in particular to a force feedback structure and an interactive device. Background Art

[0002] Interactive terminal devices often need to provide corresponding force feedback based on the user's force operations such as pressing and pushing. The force feedback is transmitted to the user, allowing the user to feel feedback effects such as vibration and shaking, thereby improving the user's interactive experience with the device.

[0003] In related technologies, the force feedback structure in interactive terminal devices is generally complex, with significant force transmission losses and poor force feedback effects. Taking the force feedback of a trigger on a handle as an example, the handle typically uses a motor as the power source, which transmits feedback force to the trigger through multiple transmission components such as a worm gear, worm, connecting rod, and push rod. The trigger then provides force feedback to the user. Transmitting feedback force through multiple transmission components not only increases the structural complexity of the force feedback structure, but also introduces significant transmission losses, increased motor output requirements, and poor force feedback effects at the trigger end. Summary of the Invention

[0004] The main purpose of the present invention is to propose a force feedback structure, aiming to simplify the force feedback structure and improve the force feedback effect.

[0007] a trigger assembly, the trigger assembly comprising a trigger rotatably connected to the housing and at least two first magnets disposed on the trigger, the trigger passing through the through opening and partially located within the mounting slot; and

[0008] At least two coil assemblies are provided in the mounting groove and are respectively located on both sides of the trigger; the coil assemblies are used to apply a force to the first magnet when energized, so that the first magnet drives the trigger to rotate.

[0010] In one embodiment of the present invention, the force feedback structure further includes a second magnet, which is disposed on a side wall of the mounting slot facing the through opening and is configured to exert a repulsive force on the first magnet closest to the side wall.

[0011] In one embodiment of the present invention, at least two first magnets are spaced apart on the trigger along the moving direction of the trigger, the magnetization direction of each first magnet is perpendicular to the moving direction of the trigger, and the magnetization directions of two adjacent first magnets are opposite.

[0012] In one embodiment of the present invention, each of the coil assemblies includes a skeleton and a coil;

[0013] The two skeletons are accommodated in the mounting groove and are respectively located on both sides of the trigger; an annular groove is provided on the outer peripheral wall of each skeleton, and each coil is wound in the annular groove along the circumference of the bottom wall of the annular groove.

[0014] In one embodiment of the present invention, limiting posts are provided on opposite side walls of the installation slot;

[0036] Interactive devices are generally equipped with a force feedback structure. The force feedback structure in the relevant interactive devices is often complex in structure. The power output by the power source often needs to pass through multiple transmission parts to be transmitted to the output end of the force feedback, which brings more force transmission losses. The force feedback effect output by the force feedback end is often greatly reduced, which is not conducive to reducing the output power and energy consumption of the power source.

[0037] In response to the above technical problems, the present invention proposes a force feedback structure. The force feedback structure is achieved by disposing a coil assembly 5 in the mounting groove 11 of the housing 1 and disposing at least two first magnets 22 on the trigger 21 that is movably inserted into the opening 12 of the housing 1. When the coil assembly 5 is energized, the at least two first magnets 22 can apply an Ampere force to the coil assembly 5, and the coil assembly 5 also applies a reaction force of the Ampere force to the first magnet 22. In this way, when the coil assembly 5 is fixed, the force applied by the coil assembly 5 on the first magnet 22 will drive the first magnet 22 and drive the trigger 21 to move along the opening 12 toward the inside or outside of the mounting groove 11, providing force feedback output to the user through the trigger 21. The force feedback structure of the present invention avoids the design of multiple intermediate transmission parts, avoiding the force transmission loss caused by multiple transmission parts. The overall structure is simple. Under the drive of the coil assembly 5, the force feedback action of the trigger 21 is rapid, which is conducive to improving the force feedback effect of the trigger 21.

[0038] Combine Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the force feedback structure includes a housing 1, a trigger assembly 2, and at least two coil assemblies 5. The housing 1 is provided with a mounting slot 11 and a through-hole 12 communicating with the mounting slot 1. The trigger assembly 2 includes a trigger 21 rotatably connected to the housing 1 and at least two first magnets 22 disposed on the trigger 21. The trigger 21 passes through the through-hole 12 and is partially located within the mounting slot 11. The at least two coil assemblies 5 are disposed within the mounting slot 11, one on each side of the trigger 2. When energized, the coil assemblies 5 are configured to apply a force to the first magnets 22, causing the first magnets 22 to rotate the trigger. In this embodiment, the housing 1 can be a magnetically conductive structure, such as a yoke. The through-hole 12 in the housing 1 can be formed through the sidewall of the mounting slot 11, communicating with the interior of the mounting slot 11. The trigger 21 serves as a force feedback output terminal, providing force feedback to the user, thereby enabling interaction between the interactive device employing this force feedback structure and the user. One end of the trigger 21 can be rotatably connected to one end of the shell 1, and the free end of the trigger 21 can be movably inserted into the through opening 12. When the trigger 21 rotates, the free end of the trigger 21 can move into the mounting groove 11 through the through opening 12 or move to the outside of the shell 1 through the through opening 12.

[0039] At least two first magnets 22 may be spaced apart along a first direction, which may be the direction of movement of the trigger 2. The two coil assemblies 5 may be spaced apart along a second direction, which may be the axial direction of the at least two coil assemblies 5 when coaxially arranged. The first direction and the second direction are not parallel. This ensures that the magnetic field generated by the magnetic circuit formed by the two first magnets 22 can exert an Ampere force on the two coil assemblies 5, enabling the trigger 21 to move rapidly under the action of the two coil assemblies 5.

[0040] When this force feedback structure is in use, the trigger 2 is pressed and moves into the mounting slot 11. The energized coil assembly 5 cuts the magnetic field generated by at least two first magnets 22 on the trigger 21. The first magnets 22 exert an Ampere force on the coil assembly 5. The coil assembly 5 then exerts a reaction force on the first magnets 22, forcing the first magnets 22 to drive the trigger 2 toward the inside or outside of the mounting slot 11. The coil assembly 5 further cuts the magnetic field generated by the first magnets 22 to maintain the trend of movement. The magnitude and direction of the force exerted by the coil assembly 5 on the first magnets 22 can be controlled by controlling the current within the coil assembly 5. For example, when a positive current is passed through the coil assembly 5, the force exerted by the coil assembly 5 on the first magnets 22 is manifested as driving the first magnets 22 to drive the trigger 2 toward the inside of the mounting slot 11. When a reverse current is passed through the coil assembly 5, the force exerted by the coil assembly 5 on the first magnets 22 is manifested as driving the first magnets 22 to drive the trigger 2 toward the outside of the mounting slot 11. By changing the magnitude of the current flowing into the coil assembly 5, the magnitude of the force applied by the coil assembly 5 to the first magnet 22 can be correspondingly changed. In this way, the magnitude of the feedback force output by the trigger 21 to the user has many possibilities, which can greatly enrich the force feedback form of the trigger 21 and enhance the force feedback effect of this force feedback structure.

[0041] When the coil assembly in the force feedback structure of this embodiment is energized, the magnetic field generated by the at least two first magnets 22 exerts an Ampere force on the coil assembly 5. When the coil assembly 5 is fixed with the housing 1, the at least two first magnets 22, driven by the reaction force of the Ampere force exerted by the coil assembly 5, move the trigger 2 along the opening 12 toward the inside or outside of the mounting slot 11, thereby providing force feedback to the user through the trigger 2. The force feedback structure of the present invention avoids the design of multiple intermediate transmission components, thereby avoiding the force transmission losses caused by multiple transmission components. The overall structure is simple. Under the drive of the coil assembly 5, the force feedback action of the trigger 2 is rapid, which is conducive to improving the force feedback effect of the trigger 2.

[0042] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, at least two first magnets 22 are spaced apart on the trigger 2 along the moving direction of the trigger 2 , and the polarities of adjacent sides of two adjacent first magnets 22 are the same.

[0043] In this embodiment, the magnetization direction of each first magnet 22 is perpendicular to the axial direction of the coil assembly 5. When the first magnet 22 and the coil assembly 5 generate relative motion and the coil assembly 5 is energized, at least two first magnets 22 can apply Ampere force to the coil assembly 5. The coil assembly 5 applies a reaction force of the Ampere force to the first magnet 22, and drives the first magnet 22 to drive the trigger 21 to move along the opening 12 toward the inside or outside of the mounting groove 11, providing force feedback output to the user through the trigger 21.

[0044] Optionally, the force feedback structure further includes a second magnet 3, which is disposed on the side wall of the mounting slot 11 facing the through opening 12 and is configured to exert a repulsive force on the first magnet 22 closest to the side wall. When current is passed through the coil assembly 5 in different directions, the force exerted by the coil assembly 5 on the first magnet 22 can manifest as a thrust that pushes the first magnet 22 toward the outside of the mounting slot, or a pull that pulls the first magnet 22 toward the inside of the mounting slot. The above-mentioned thrust or pull applied by the coil assembly 5 to the first magnet 22 will be combined with the repulsive force applied by the second magnet to the first magnet 22, so that the force acting on the first magnet 22 is the above-mentioned repulsive force minus the above-mentioned pulling force, and the resultant force on the first magnet 22 is manifested as a tendency for the first magnet 22 to move toward the outside of the installation slot; or, the force acting on the first magnet 22 is the above-mentioned repulsive force plus the above-mentioned pulling force, and the resultant force on the first magnet 22 is manifested as a tendency for the first magnet 22 to move toward the outside of the installation slot; so as to enrich the size and form of the force feedback output by the trigger, and after the trigger 2 is pressed and moves into the installation slot 11, the trigger 2 can be reset under the action of the coil assembly 5 and the second magnet 3.

[0045] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, at least two first magnets 22 are spaced apart on the trigger 2 along the moving direction of the trigger 2 . The magnetizing direction of each first magnet 22 is perpendicular to the moving direction of the trigger 2 , and the magnetizing directions of two adjacent first magnets 22 are opposite.

[0046] In this embodiment, the magnetization direction of the first magnet 22 is perpendicular to the movement direction of the trigger 2. When the trigger 2 is pressed to move into the mounting slot 11, the coil assembly 5 perpendicularly cuts the magnetic flux lines of the magnetic field generated by the first magnet 22. At this time, the coil assembly 5 can exert a strong force on the first magnet 22, driving the first magnet 22 to drive the trigger to move quickly, thereby improving the force feedback speed of the trigger 22.

[0047] Optionally, the force feedback structure further includes an elastic member (not shown), which connects the trigger 2 and the side wall of the mounting slot 11 facing the opening 12 and is located between the trigger 2 and the side wall of the mounting slot 11. When the coil assembly 2 is energized and applies a force to the first magnet 22 to move inwardly of the mounting slot 11, the first magnet 22 drives the trigger 2 to move inwardly of the mounting slot 11, at which time the elastic member is compressed. When the coil assembly 5 is de-energized, the force applied by the coil assembly 5 to the first magnet 22 disappears, the elastic member elastically stretches and pushes the trigger 2, allowing the trigger 2 to reset. The elastic member can be a spring, an elastic sleeve, etc., which is not limited here.

[0048] To improve the reliability and stability of the connection between the trigger 21 and the housing 1:

[0049] Combine Figure 1 、 Figure 3 as well as Figure 4 As shown, in one embodiment of the present invention, one end of the shell 1 is provided with two spaced-apart protrusions 13, and one end of the trigger 21 is provided with an axial hole 211; the force feedback structure also includes a rotating shaft 4 passing through the axial hole 211 and the two protrusions 13, and the trigger 21 is rotatably connected to the shell 1 through the hole-axis fit of the axial hole 211 and the rotating shaft 4.

[0050] In this embodiment, the protrusion 13 is a protruding structure extending from one end of the shell 1. The protrusion 13 can be provided with an opening for the rotating shaft 4 to pass through. The two ends of the rotating shaft 4 are respectively arranged in the two openings, and the middle part of the rotating shaft 4 passes through the shaft hole 211 on the trigger 21. The trigger 21 is located between the two protrusions 13. In this way, when the trigger 21 is pressed, the free end of the trigger 21 is limited in the through opening 12. The free end of the trigger 21 can be rotated into the mounting groove 11 through the shaft hole 211 and the hole axis of the rotating shaft 4, thereby realizing a stable and reliable connection between the trigger 21 and the shell 1.

[0051] When the trigger 21 rotates, a portion of it is always located within the mounting groove 11, while the other portion is located outside the housing 1. The trigger 21 is defined as being able to rotate relative to the housing 1 at an angle α, 20°≤α≤30°. This ensures that the rotation angle of the trigger 21 is not too large, thereby preventing the coil assembly 5 from exerting too little force on the first magnet 22, thereby maintaining reliable driving of the first magnet 22 by the coil assembly 5. To prevent the trigger 21 from completely sliding out of the mounting groove 11 through the opening 12 during rotation, a stopper protrusion may be provided on the portion of the trigger 21 located within the mounting groove 11. When the trigger 21 moves to a certain extent outside the housing 1, the stopper protrusion abuts against the sidewall of the mounting groove 11, thereby preventing the trigger 21 from further rotating and sliding out of the mounting groove 11.

[0052] Optionally, combined Figure 4 and Figure 5 As shown, each coil assembly 5 includes a frame 51 and a coil 52. Each frame 51 is housed within the mounting slot 11 and positioned on either side of the trigger 2. An annular groove 511 is defined on the outer peripheral wall of each frame 51, and each coil 52 is wound within the annular groove 511 along the circumference of the bottom wall of the annular groove 511. The coil 52 may comprise multiple turns of wire wound around the frame 51 and confined within the annular groove 511. When current flows through the coil 52, each coil 52 forms a closed conductive loop. When the trigger 2 and the coil 52 move relative to each other, the coil 52 cuts the magnetic flux lines of the magnetic field generated by the first magnet 22, generating an interaction force between the coil 52 and the first magnet 22. When the coil 52 is fixed by the mounting of the housing, the force exerted by the coil 52 on the first magnet 22 drives the first magnet 22 to move the trigger 2 inward or outward of the mounting slot 11, thereby achieving force feedback output from the trigger 21.

[0053] To ensure the reliability of the frame 51 being installed and fixed in the installation groove 11:

[0054] Combine Figure 4 and Figure 5 As shown, in one embodiment of the present invention, the opposite side walls of the mounting groove 11 are provided with limiting columns 14; each frame 51 is provided with a limiting hole 512, each annular groove 511 is arranged around a limiting hole 512, and the two limiting columns 14 are respectively inserted into the two limiting holes 512.

[0055] In this embodiment, the opposite side walls of the mounting groove 11 can be two side walls connected to the side walls of the mounting groove 11 facing the through opening 12, and the two limiting columns 14 are respectively arranged on the opposite side walls of the mounting groove 11 and are respectively located on the opposite sides of the trigger 2. The two limiting columns 14 can be coaxially arranged, and each limiting column 14 is plugged into a limiting hole 512. Each skeleton 51 is fixed in the mounting groove 11 through the plug-in cooperation between the limiting hole 512 and the limiting column 14, thereby realizing reliable installation and fixation of the skeleton 51. At the same time, the coil 52 is limited in the annular groove 511 of the skeleton 51, and the coil 52 is fixed as the skeleton 51 is fixed. Among them, the outer wall of the limiting column 14 can be provided with multiple ribs, and the side wall of the limiting hole 512 can be opened with multiple rib grooves. When the limiting column 14 is plugged into the limiting hole 512, each rib is clamped in a rib groove, thereby preventing the limiting column 14 from rotating relative to the limiting hole 512, and improving the reliability of the frame 51 being installed and fixed on the limiting column 14.

[0056] In order to enable the electromagnetic field generated when the coil 52 is energized to provide a more reliable and stronger driving force to the two first magnets 22:

[0057] Combine Figure 4 and Figure 5 As shown, in one embodiment of the present invention, the bottom wall of the annular groove 511 includes a plurality of straight segments 5111 and a plurality of corner segments 5112; the two ends of each straight segment 5111 are respectively connected to two corner segments 5112, and the two ends of each corner segment 5112 are respectively connected to two straight segments 5111, so that the plurality of straight segments 5111 and the plurality of corner segments 5112 are connected to form a ring.

[0058] In this embodiment, the bottom wall of the annular groove 511 is a non-circular annular structure, such as an annular structure with a triangular cross-section. The bottom wall of the annular groove 511 is formed by connecting a plurality of straight segments 5111 and corner segments 5112. The straight segments 5111 are the straight extending portions of the bottom wall of the annular groove 511, and the corner segments 5112 are the curved or bent portions of the bottom wall of the annular groove 511. The bottom wall of the annular groove 511 is arranged in a pattern of straight segments 5111, corner segments 5112, straight segments 5111, corner segments 5112, straight segments 5111, etc., with the straight segments 5111 and the corner segments 5112 being alternately arranged and sequentially connected to form a ring. The advantage of adopting this structural design for the annular groove 511 is that, after the coil 52 is wound circumferentially around the bottom wall of the annular groove 511, the coil 52 also becomes a non-circular annular coil 52. This makes it easier to design the coil 52 so that, when the trigger 2 rotates, the coil 52 cuts as many magnetic flux lines generated by the first magnet 22 as possible. Consequently, under the action of the two coils 52, the first magnet 22 can be driven more quickly and accurately, simultaneously driving the trigger 21 to provide rapid and accurate force feedback.

[0059] To improve the reliability of the connection between the first magnet 22 and the trigger 21:

[0060] Combine Figure 2 and Figure 4 As shown, in one embodiment of the present invention, the trigger 21 is provided with at least two limiting slots 212 spaced apart from each other, and each first magnet 22 is accommodated and limited in a limiting slot 212 .

[0061] In this embodiment, at least two limiting grooves 212 may be spaced apart along the first direction, with the notch of each limiting groove 212 facing upward. Each first magnet 22 is inserted into a limiting groove 212, and the outer peripheral wall of each first magnet 22 abuts against the inner peripheral wall of a limiting groove 212 to limit the position, so that the two first magnets 22 are reliably fixed on the trigger 21. Optionally, to further improve the reliability of the first magnet 22 being fixed in the limiting groove 212, the first magnet 22 can be bonded to the groove wall of the limiting groove 212 by glue.

[0062] To prevent the trigger 21 from completely sliding into the mounting slot 11:

[0063] Combine Figures 1 to 3 As shown, in one embodiment of the present invention, the trigger 21 is provided with a stop portion 213 ; the stop portion 213 is located outside the housing 1 and is used to cooperate with the peripheral stop of the through opening 12 .

[0064] In this embodiment, the stop portion 213 can be a raised structure on the end of the trigger 21 away from the second magnet 3. When the trigger 21 is pressed and slides a certain distance into the mounting groove 11, the stop portion 213 will abut against the periphery of the opening 12 and stop the trigger 21 from continuing to move into the mounting groove 11. This can prevent the trigger 21 from sliding completely into the mounting groove 11, and at the same time prevent the first magnet 22 on the trigger 21 from partially moving to the rear side of the coil assembly 5, so that the repulsive force applied by the coil assembly 5 to the first magnet 22 cannot drive the first magnet 22 to drive the trigger 21 to move out of the mounting groove 11, causing the trigger 21 to be unable to reset.

[0065] An embodiment of the present invention also proposes an interactive device, which includes the force feedback structure in the above embodiment. Among them, the interactive device includes but is not limited to a game controller and a somatosensory device. The interactive device can provide corresponding feedback information according to the user's operation. For example, when the interactive device is a game controller, the interactive device provides corresponding damping feedback on the key body according to the user's pressing operation on the key. The force feedback structure in the interactive device can be used to provide different trigger 21 force feedback experiences according to the game content or game scene, so as to enrich the force feedback form and enhance the human-computer interaction experience. The specific structure of the force feedback structure in this interactive device refers to the above embodiment. Since the interactive device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0066] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
