The present embodiments provide a force feedback device that includes two parts, a trigger and a tactile feedback assembly.
The trigger comprises a bracket 12, a trigger 13 and a second elastic piece, wherein the trigger 13 is rotatably arranged on the bracket 12 through a hinged shaft; the second elastic component is a torsion spring sleeved on the hinged shaft, one torsion arm of the torsion spring is connected with the bracket 12, and the other torsion arm is connected with the trigger 13.

First elastic component 3, balanced magnetism group 11 and electromagnetic component then act on main part 2 and supporting part respectively to drive main part 2 and supporting part and take place relative movement according to the mode of predetermineeing, and then realize the force feedback control to trigger 13, thereby provide abundant force feedback for trigger 13.
The main body 2 is a cylindrical shell structure, and comprises a cylinder with one end sealed at the bottom and an end cover in adaptive connection with the cylinder, and is suitable for providing an installation space. The supporting part comprises a connecting part 1, a sliding part 7 and a connecting rod 8, wherein the sliding part 7 is annular, is shorter than the cylinder in height and is suitable for being attached to the inner side surface of the cylinder in the main body 2 through the outer side surface to realize relative sliding; the connecting rod 8 is a plurality of, and the one end of a plurality of connecting rods 8 all is connected on the cyclic annular terminal surface of sliding part 7, and the other end sets up from the main part 2 end cover dodges the hole and stretches out and be connected with circular shape connecting portion 1. In practical application, one of the main body 2 and the supporting portion may be fixedly mounted on the bracket 12, and the other may be detachably contacted with the trigger 13, specifically, in this embodiment, the supporting portion is fixedly connected to the bracket 12, and the main body 2 is detachably contacted with the trigger 13.
The first elastic part 3 is a spring, one end of the spring is abutted to the connecting part 1, the other end of the spring is abutted to the end cover of the main body 2, and in the working state, the spring is in a compressed state and is suitable for applying a supporting force in the opposite direction to the main body 2 and the supporting part. In order to ensure the state of the spring, a limiting column 9 for sleeving the spring is also erected on the side surface of the connecting part 1 facing the end cover. Specifically, the length of the limit post 9 is greater than the fully compressed length of the spring and less than the natural length of the spring, so as to limit the relative range of motion between the support part and the main body 2, and simultaneously avoid the spring from losing elasticity due to the full compression. The spring is that the magnitude of the supporting force applied by the supporting part and the main body 2 is in direct proportion to the deformation length thereof, namely, the relative displacement of the supporting part of the main body 2.
The electromagnetic component comprises a magnetic circuit component and a coil 6 which is correspondingly arranged, wherein one of the magnetic circuit component and the coil 6 is connected with the main body 2, the other one is connected with the supporting part, the coil 6 is positioned in a magnetic field formed by the permanent magnet, and is acted by ampere force during power-on, so that driving force capable of driving the main body 2 and the supporting part to move relatively can be applied to the main body 2 and the supporting part during power-on, and the magnitude of the driving force is in direct proportion to the relative displacement of the main body and the supporting part. In this embodiment, the permanent magnet is connected to the main body 2 and is fixedly disposed in the inner cavity of the main body 2. Specifically, the magnetic circuit assembly includes a first magnetic member 4 and a second magnetic member 5, and the first magnetic member 4 and the second magnetic member 5 are both columnar and are sequentially spaced along the central axis of the sliding portion 7 in a manner that opposite poles are opposite to each other and are disposed in the main body. First magnetic part 4 and second magnetic part 5 accessible bonding mode such as with main part 2 fixed connection, can also make first magnetic part 4 and the bottom surface butt of main part 2, second magnetic part 5 and end cover butt through setting up magnetic conduction board 10 between first magnetic part 4 and second magnetic part 5. The first magnetic member 4 and the second magnetic member 5 are used for providing a stable magnetic field, and the direction of the magnetic field is parallel to the relative sliding direction of the support part and the main body 2. The coil 6 is connected with the supporting part and is wound in an annular groove on the outer annular surface of the sliding part 7, so that the coil is sleeved outside the magnetic assembly. When the power is on, the coil 6 takes ampere force as driving force, and then drives the sliding part 7 to move in the main body 2, so that the relative sliding between the supporting part and the main body 2 is realized, and the control of the driving force and the driving direction can be realized through the control of the current direction and the current magnitude.
The balance magnetic group 11 is arranged on the main body 2 or the supporting part and is attracted with the other one, so that an attractive magnetic acting force exists between the main body 2 and the supporting part, the balance magnetic group 11 comprises permanent magnets which are arranged in pairs, and the magnetizing directions of the two paired permanent magnets are opposite and are parallel to the sliding directions of the main body and the supporting part. Specifically, two permanent magnets arranged in pairs are cuboids, and the side surfaces of the two cuboids where the non-magnetic poles are located are attached to each other. Specifically, the number of the balance magnetic groups 11 is plural, and the balance magnetic groups are uniformly embedded in the connecting portion 1 of the supporting portion, preferably, in order to avoid the influence of the balance magnetic groups 11 on the relative displacement between the supporting portion and the main body 2, the plurality of balance magnetic groups 11 are uniformly distributed on the plane of the connecting portion 1 far away from the main body 2, and are distributed in the process of being distributed. In order to achieve attraction with the balance magnet assembly 11, in this embodiment, the end cap is made of a magnetic material to attract the balance magnet assembly 11. The arrangement of the balance magnet group 11 enables the magnetic induction lines of the two permanent magnets to form a loop basically when the support part and the main body 2 are far away, and attract the main body 2 when the support part and the main body 2 are near, so that the magnetic force brought by the balance magnet group has a small value and a small correlation between the value change and the stroke when the main body and the support part are far away, and has a large value and a large correlation between the value change and the stroke when the main body and the support part are near, that is, the relationship between the magnetic force provided by the balance magnet group 11 and the relative displacement between the main body 2 and the support part is shown in fig. 6 c.
Because the supporting portion is fixed on the bracket 12 and the main body 2 is detachably contacted with the trigger 13, when the main body 2 is contacted with the trigger 13, the tactile feedback assembly is in a working mode, and when the main body 2 is separated from the trigger 13, the tactile feedback assembly is in a non-feedback mode. Correspondingly, the maximum stroke position of the main body 2 is set as A, and the trigger 13 is in the initial position and is abutted against the main body 2; taking the middle stroke position of the main body 2 as B, the trigger 13 is at the end-of-movement position and is abutted against the main body 2; when the main body 2 and the support portion are in contact with each other, the trigger 13 is completely separated from the main body 2. The haptic feedback assembly is in a force feedback mode when the body 2 is between a and B and in a no feedback mode when the body 2 is between B and C.
At this time, the control and switching of the operation mode of the haptic feedback assembly can be achieved by setting the magnitude and direction of the supporting force, the driving force, and the magnetic acting force between the main body 2 and the supporting part. Specifically, F1 denotes the feedback force of the torsion spring, F2 denotes the driving force, F3 denotes the magnetic acting force, and F4 denotes the supporting force.
The torsion spring is arranged such that the feedback force F1 of the torsion spring is of the magnitude shown in fig. 6 a.
Arranging an electromagnetic assembly to have two working states, wherein one working state is a normal state, and the force value of the driving force F2 is F2-1; one is a switching state where the force value of the driving force F2 is F2-2, and F2-2 is a multiple of F2-1. The direction of the driving force F2 can be freely adjusted for both operating states. The magnitude versus stroke curve of the specific driving force F2 is shown in fig. 6 b.
The balance magnet assembly 11 is arranged so that its abrupt change in value is between positions B-C, i.e. the magnitude of the magnetic retaining force F3 versus the travel curve is shown in fig. 6C.
The supporting force F4 is set such that its magnitude versus stroke curve is shown in fig. 6 d.
The size relationships of F2, F3 and F4 are set so that F4-F2-1 > F3 > F4-F2-2 when F3 is between position A and position B, and F4+ F2-2 > F3 > F4 when F3 is at position C.
Through the arrangement, the force feedback device has the following working modes:
a no feedback mode: the tactile feedback assembly is disengaged from trigger 13, and trigger 13 is acted upon only by torsion spring feedback force F1;
a powerful feedback mode: the tactile feedback assembly intervenes between trigger travel positions A-B, the body 2 cannot pass position B to return to position C for self-retention due to F4-F2-1 > F3 > F4-F2-2, and can provide force feedback to the trigger 13 between position A and position B, with the force feedback threshold range of the trigger 13 being F1+ F4-F2-1 to F1+ F4+ F2-1.
Mode switching:
and (4) exiting the feedback mode: switching F2 to F2-2 mode and directing its direction to the support, where F3 > F4-F2-2, the mover 4 retracts, and at position C F3 > F4, so that the body 2 is self-retaining after de-energizing the electromagnetic assembly of the tactile feedback assembly after it has stopped operating;
intervention feedback mode: the electromagnetic assembly is activated and F2 is configured to F2-2 mode and opposite to the magnetic holding force F3, at position C, F3 < F4+ F2-2, the main body 2 is disengaged from the support and enters the force feedback mode.
And because the numerical value of the magnetic acting force is suddenly changed between the positions B-C, the magnetic acting force F3 is very small in the section A-B and is suddenly increased when approaching the point C, the phenomenon of mistaken attraction of the touch feedback assembly at the position B is further avoided, and the control can be accurately realized, so that abundant force feedback experience is provided.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
