Description

Exciter and electronic equipment

Technical Field

The invention relates to the technical field of vibration devices, in particular to an exciter and electronic equipment using the same.

Background

Conventional vibration devices create the illusion of "acting as if it were oriented in a certain direction" by constantly making asymmetric vibrations, which are also referred to as anisotropic vibrations.

There are two means for realizing the force sense, namely, a method for inputting an asymmetric signal to a linear resonator and generating illusion by using human sense. In principle, this method only produces a continuous directional force sensation, and does not allow discrete vibration outputs. Meanwhile, the equivalent force perceived by the method is small, and the asymmetric signal can generate redundant vibration, so that clear sense of direction is difficult to obtain. The other is to generate a strong force sense by rapidly braking the linear resonator. The method can generate vibration with large asymmetry, and has the characteristics of small redundant vibration proportion and individual and clear force sense. However, this method requires that the vibration part and the braking part are independently formed, and the vibration part or the braking part is continuously moved to switch the energy storage and braking states, so that the high-speed continuous operation is not possible, and the structure of the device is complicated.

However, this type of device only achieves vibration in a straight direction, and does not generate a force feeling in a rotation direction.

Optionally, the first rotating assembly 2 is arranged close to the second side wall 13 and the fourth rotating assembly 5 is arranged close to the first side wall 12.

In the present embodiment, the first rotating portion 22/second rotating portion 32/third rotating portion 42/fourth rotating portion 52 is respectively connected to the output ends of the first driving member 21/second driving member 31/third driving member 41/fourth driving member 51 and is eccentrically disposed. It will be appreciated that the first rotating portion 22/second rotating portion 32/third rotating portion 42/fourth rotating portion 52 may be an eccentric structure, or one end of the first rotating portion 22/second rotating portion 32/third rotating portion 42/fourth rotating portion 52 may be connected to the output end of the first driving member 21/second driving member 31/third driving member 41/fourth driving member 51, so that when the first driving member 21/second driving member 31/third driving member 41/fourth driving member 51 drives the first rotating portion 22/second rotating portion 32/third rotating portion 42/fourth rotating portion 52 to rotate, the first rotating portion 22/second rotating portion 32/third rotating portion 42/fourth rotating portion 52 moves circumferentially around the output end of the first driving member 21/second driving member 31/third driving member 41/fourth driving member 51, that is, the position where the first rotation portion 22/second rotation portion 32/third rotation portion 42/fourth rotation portion 52 is connected to the output end of the first driver 21/second driver 31/third driver 41/fourth driver 51 is located at an eccentric position of the first rotation portion 22/second rotation portion 32/third rotation portion 42/fourth rotation portion 52 itself (the position where the first rotation portion 22/second rotation portion 32/third rotation portion 42/fourth rotation portion 52 is connected to the output end of the first driver 21/second driver 31/third driver 41/fourth driver 51 does not coincide with the center of the first rotation portion 22/second rotation portion 32/third rotation portion 42/fourth rotation portion 52).

It should be noted that, in the present embodiment, the structures of the first rotating assembly 2, the second rotating assembly 3, the third rotating assembly 4 and the fourth rotating assembly 5 are the same or similar, that is, the first rotating assembly 2, the second rotating assembly 3, the third rotating assembly 4 and the fourth rotating assembly 5 all include a driving member structure and a rotating portion structure, and the rotating portion structure is connected to the output end of the driving member structure and is eccentrically disposed. It can be understood that the rotating part structure can be an eccentric structure, or one end of the rotating part structure is connected to the output end of the driving part structure, so that when the driving part structure drives the rotating part structure to rotate, the rotating part structure performs circular motion around the output end of the driving part structure, that is, the output end of the driving part structure is located at the eccentric position of the rotating part structure.

In the present embodiment, the actuator has a clockwise rotation feeling by controlling the first and second rotary members 2 and 3 to operate, and has a counterclockwise rotation feeling by controlling the third and fourth rotary members 4 and 5 to operate. It will be appreciated that the actuator 100 may utilize a long, high frequency drive to produce a fast, multiple frequency, two unidirectional rotational sensations on the same axis, i.e., the actuator 100 produces a clockwise rotational sensation and a counter-clockwise rotational sensation.

It will be appreciated that by simultaneously controlling the first driving member 21 and the second driving member 31 to synchronously drive the first rotating portion 22 and the second rotating portion 32 such that the first rotating portion 22 and the second rotating portion 32 simultaneously strike the second side wall 13 and the second partition 15, respectively, or such that the first rotating portion 22 and the second rotating portion 32 simultaneously strike the first partition 14, it is possible to achieve the effect of two extreme positions, that is, when the first rotating portion 22 and the second rotating portion 32 simultaneously strike the second side wall 13 and the second partition 15, respectively, torque can be generated in the clockwise rotation direction, so that the actuator 100 can generate a force sense in the clockwise rotation direction, that is, a sense of rotation in a single direction is formed, and the first rotating portion 22 and the second rotating portion 32 simultaneously strike the first partition 14 to generate forces in opposite directions, thereby canceling out, so that it can be ensured that the actuator 100 can generate a force sense in the single rotation direction.

Of course, by simultaneously controlling the third driving member 41 and the fourth driving member 51 to synchronously drive the third rotating portion 42 and the fourth rotating portion 52 such that the third rotating portion 42 and the fourth rotating portion 52 simultaneously strike the second partition 15 and the first side wall 12, respectively, or such that the third rotating portion 42 and the fourth rotating portion 52 simultaneously strike the first partition 14, respectively, it is possible to achieve the effect of two extreme positions, that is, when the third rotating portion 42 and the fourth rotating portion 52 simultaneously strike the second partition 15 and the first side wall 12, respectively, torque can be generated in the counterclockwise rotating direction, so that the actuator 100 can generate a force sense in the counterclockwise rotating direction, that is, a sense of rotation in a single direction is formed, and the third rotating portion 42 and the fourth rotating portion 52 simultaneously strike the first partition 14 to generate a force in the same direction and opposite directions, thereby canceling, so that it is ensured that the actuator 100 can generate a force sense in the single direction.

Meanwhile, by setting the first rotating assembly 2/second rotating assembly 3/third rotating assembly 4/fourth rotating assembly 5 to the rotating structure of the first driving member 21/second driving member 31/third driving member 41/fourth driving member 51 driving the eccentrically disposed first rotating portion 22/second rotating portion 32/third rotating portion 42/fourth rotating portion 52, not only is the structure of the actuator 100 effectively simplified, but also the actuator 100 is made to realize a high-speed continuous operation, and a strong and clear force feeling is generated.

The actuator 100 further includes a controller or control structure capable of controlling the first driver 21 and the second driver 31 to drive the first rotating portion 22 and the second rotating portion 32 to rotate, or controlling the third driver 41 and the fourth driver 51 to drive the third rotating portion 42 and the fourth rotating portion 52 to rotate. It is understood that the controller or control structure may be a separate controller or remote controller, or may be a control circuit or control key integrated on the actuator 100, which is not limited herein.

In the present embodiment, as shown in fig. 3 to 6, the first rotating member 2 and the second rotating member 3 are located between the second side wall 13 and the extension line of the second partition 15, and the third rotating member 4 and the fourth rotating member 5 are located between the first side wall 12 and the extension line of the second partition 15.

It should be noted that, as shown in fig. 3, the first driving member 21 and the second driving member 31 are controlled to rotate in the forward direction to drive the first rotating portion 22 and the second rotating portion 32 to rotate in the clockwise direction, so that the first rotating portion 22 and the second rotating portion 32 simultaneously strike the second side wall 13 and the second partition 15, respectively, thereby generating a torque in the clockwise direction, so that the actuator 100 can generate a force sense in the clockwise direction, and as shown in fig. 4, the first driving member 21 and the second driving member 31 are controlled to rotate in the reverse direction to drive the first rotating portion 22 and the second rotating portion 32 to rotate in the counterclockwise direction, so that the first rotating portion 22 and the second rotating portion 32 strike the first partition 14 simultaneously, thereby generating a force in the same direction and opposite to the counterclockwise direction, so as to cancel, so that the actuator 100 can generate a force sense in the clockwise direction.

As shown in fig. 5, the third driving member 41 and the fourth driving member 51 are controlled to rotate in the forward direction to drive the third rotating portion 42 and the fourth rotating portion 52 to rotate in the counterclockwise direction, so that the third rotating portion 42 and the fourth rotating portion 52 simultaneously strike the first sidewall 12 and the second partition 15, respectively, thereby generating a torque in the counterclockwise direction so that the actuator 100 can generate a force feeling in the counterclockwise direction, and as shown in fig. 6, the third driving member 41 and the fourth driving member 51 are controlled to rotate in the reverse direction to drive the third rotating portion 42 and the fourth rotating portion 52 to rotate in the clockwise direction, so that the third rotating portion 42 and the fourth rotating portion 52 simultaneously strike the first partition 14, thereby generating a force in the opposite direction in the clockwise direction so as to cancel, thus ensuring that the actuator 100 can generate a force feeling in the counterclockwise direction in the unidirectional direction.

It will be appreciated that when the fourth rotating portion 52 impacts the first sidewall 12/first baffle 14, the fourth rotating portion 52 forms a fourth impact point 121 on the first sidewall 12/first baffle 14, the fourth impact point 121 coinciding with the fourth impact point.

In the present embodiment, the fourth buffer portion 53 may be provided on the first side wall 12 and/or the first partition 14 of the housing 1, and located at the fourth impact. Of course, the fourth buffer portion 53 may be disposed on the fourth rotating portion 52, so that the fourth buffer portion 53 abuts against the fourth impact portion when the fourth driving member 51 drives the fourth rotating portion 52 to rotate.

In the present embodiment, the fourth buffer portion 53 includes a plurality of fourth buffer portions 53, and the plurality of fourth buffer portions 53 are provided on the first side wall 12 and the first separator 14, respectively.

It will be appreciated that when the rotor motor is driven, the first 22/second 32/third 42/fourth 52 rotary portions rotate rapidly about the rotational axis 211 of the rotor motor. When the first rotary part 22/second rotary part 32/third rotary part 42/fourth rotary part 52 moves to the two limit movement positions, they collide with the corresponding second side wall 13/second partition 15, second partition 15/first side wall 12 of the housing 1, respectively. When the first rotating portion 22/second rotating portion 32/third rotating portion 42/fourth rotating portion 52 collides with the housing 1, a rapid braking effect is generated and a corresponding impact feeling is received on the housing 1. By driving a plurality of rotor motors in combination, the effect of two limit states, that is, one side is a sense of rotation in one direction and the other side is a sense of rotation in the same direction, can be achieved. The magnitude of the rotational feel on both sides is related to the product of the corresponding force and moment arm. And further, the two unidirectional rotation touch feeling, namely clockwise rotation touch feeling and anticlockwise rotation touch feeling, of the same coordinate axis with high speed and multiple frequencies are generated by long-time and high-frequency driving.

When the first rotating portion 22 and the second rotating portion 32 move to the limit positions, the impact forces of the first rotating portion 22 and the second rotating portion 32 on the housing 1 are parallel to each other and the moment arms are equal, so that the effect of simple clockwise rotation touch feeling is achieved. When the third rotary part 42/fourth rotary part 52 moves to the limit position, the impact forces of the third rotary part 42/fourth rotary part 52 to the housing 1 are parallel to each other and the moment arms are equal, thereby realizing the effect of simple counterclockwise rotation touch feeling.

It can be understood that in the motion cancellation state, when the first rotating portion 22 and the second rotating portion 32 rotate anticlockwise to collide with the first partition 14, two impact forces generated by the first rotating portion 22 and the second rotating portion 32 on the housing 1 are coincident with the centroid connecting line of the first rotating portion 22 and the second rotating portion 32, so that the housing 1 receives two acting forces with the same magnitude and opposite directions, and the motion impact cancellation effect is realized. In the other state, that is, when the first rotating portion 22 and the second rotating portion 32 rotate clockwise to collide with the second side wall 13 and the second partition 15, the impact forces of the first rotating portion 22 and the second rotating portion 32 on the housing 1 are equal to each other in parallel moment arms, so that the effect of simple clockwise rotation touch feeling is realized.

Of course, when the third rotating portion 42 and the fourth rotating portion 52 rotate clockwise to collide with the first partition 14, two impact forces generated by the third rotating portion 42 and the fourth rotating portion 52 on the housing 1 are coincident with the mass center connecting line of the third rotating portion 42 and the fourth rotating portion 52, so that the housing 1 receives two acting forces with the same magnitude and opposite directions, and the effect of counteracting the motion impact is achieved. In the other state, that is, when the third rotating portion 42 and the fourth rotating portion 52 rotate counterclockwise to collide with the first side wall 12 and the second partition 15, the impact forces of the third rotating portion 42 and the fourth rotating portion 52 on the housing 1 are equal to each other in parallel moment arms, thereby realizing the effect of simple counterclockwise rotation touch feeling.

In the actual use process, two limits of the same rotation can be comprehensively utilized, and one group of force arms can be longer according to the split of the structure, so that better tactile feedback is obtained, and the method is not limited.
