Specifically, the second end is formed with a mounting groove 42, the mounting groove 42 is used for accommodating the flat coil 32a, and when the flat coil 32a is driven by an ampere force, the flat coil 32a applies an acting force to a side wall of the mounting groove 42, so as to realize the force feedback of the magnetic driving of the key 2. In order to achieve the thinness possible, in the present embodiment, the mounting groove 42 is an annular groove in which the flat coil 32a is held, and the peripheral side of the flat coil 32a is held by the peripheral wall of the annular groove, and the annular groove may be set to the same height as the flat coil 32a or smaller in size to achieve the flattening while ensuring the strength of the pushing part 4.
Further, referring to fig. 4 and 7, in this embodiment, the magnet structure 31a includes a magnet assembly 30, the magnet assembly 30 includes two magnets 301, a magnetic gap is formed between the two magnets 301, the flat coil 32a is disposed in the magnetic gap, the stator 31 includes two magnets 301, and the mover 32 includes the flat coil 32 a. When the pancake coil 32a is energized with an alternating current, a portion of the pancake coil 32a that is in the magnetic gap will generate an ampere force, which can be determined according to the left-hand rule: the left hand is stretched to enable the thumb to be perpendicular to the other four fingers and in the same plane, so that the magnetic induction lines flow in from the palm of the hand, the four fingers point to the current direction, and the thumb points to the ampere force direction (namely the conductor stress direction). Therefore, the direction of the force applied to the flat coil 32a in the magnetic field can be obtained, when the resistance of the feedback force needs to be increased, the direction of the current in the flat coil 32a can be set to be the direction of the ampere force generated by the flat coil towards the finger of the user, and when the leakage force needs to be generated, the direction of the current in the flat coil 32a can be set to be the direction of the ampere force generated by the flat coil to be back to the finger of the user.
It should be noted that, since the ampere force is a force generated by the interaction between the magnet 301 and the energized conductive wire, it is understood that the stator 31 may include two magnets 301, the mover 32 includes the flat coil 32a, when the two magnets 301 are fixed to the housing 1, the flat coil 32a is driven to move by the ampere force, of course, when the flat coil 32a is fixed to the housing 1, the ampere force acts on the two magnets 301, the flat coil 32a may be regarded as the stator 31, and the two magnets 301 may be regarded as the mover 32.
Further, since the current directions of the wires of the two portions of the flat coil 32a on the cross section are arranged in opposite directions, in order to make the strength of the feedback force have a larger interval value, and to fully satisfy the experience feeling of the user, in this embodiment, the magnet groups 30 are arranged in at least two groups, two groups of the magnet groups 30 are arranged in the first direction, the polarities of the magnets 301 of the two groups of the magnet groups 30 located on the same side of the magnetic gap are arranged in opposite directions, so that the magnetic fields of the magnetic gap at the positions corresponding to the two groups of the magnet groups 30 are opposite, and the two oppositely arranged sides of the flat coil 32a in the first direction are correspondingly located in the magnetic gap corresponding to the two groups of the magnet groups 30. Thus, two opposite sides of the flat coil 32a in the first direction can simultaneously sense the same direction of ampere force, so that the theoretical value of the feedback force is doubled. Of course, adjusting the magnitude of the feedback force can change the current value of the flat coil 32a besides more magnet groups 30 and flat coils 32a, and the ampere force is larger when the current value is larger, and conversely the ampere force is smaller.
Further, in order to match with the flat and ultra-thin design of the flat coil 32a, when the installation channel is rectangular or square, the plurality of side portions further include a third side portion and a fourth side portion which are oppositely arranged, the key 2 is slidably arranged in the installation channel along the first direction, and the magnet structure 31a and the flat coil 32a are stacked between the third side portion and the fourth side portion, so that the key structure 100 is compact in structure in the thickness direction and is suitable for requirements of different types of handle triggers.
In this embodiment, the key structure 100 further includes a controller, a displacement sensor and a power supply module, the power supply module is configured to provide currents with different magnitudes and different current directions to the flat coil 32a, the displacement sensor is configured to detect a displacement signal of the key 2, and the controller is electrically connected to the displacement sensor and the power supply module to control the current magnitude and the current direction of the power supply module according to the displacement signal.
Further, referring to fig. 1, in this embodiment, the key structure 100 further includes a spring 5 disposed between the key 2 and the housing 1, wherein one end of the spring 5 is connected to the key 2, and the other end is connected to the housing 1, so as to provide a restoring force when the key 2 moves relative to the housing 1. When the user needs to press the key 2, the elastic force generated by the spring 5 is fed back to the user's finger, and provides a reset force for resetting the key 2, and during the operation of pressing the key 2, the resultant force formed by the elastic force generated by the spring 5 and the ampere force between the mover 32 and the stator 31 is fed back to the user's finger.
In practical application, when a user uses a game, the user pulls a trigger to press the key 2 to perform game operation, for example, when the user assumes that the game is racing, when an automobile in the game is in a static state, no current is generated in game information, and at this time, after the user presses the key 2, the sensed feedback force is the return elastic force generated by the spring 5; when the automobile is started, the resistance in a game scene is small at this time, the current provided by the power supply module is negative current, the negative current passes through the flat coil 32a, the direction of the ampere force generated between the negative current and the magnet structure 31a is opposite to the direction of the repulsive force, and the feedback force felt by the user is the resultant force of subtracting the ampere force from the reset elastic force, namely, the game feedback force felt by the user is small and is easy to start; similarly, when the automobile collides with an obstacle, the current provided by the power supply module is the forward current, and the direction of the ampere force is the same as that of the reset elastic force, so that the game feedback force felt by the user is the sum of the reset elastic force and the ampere force, and the feedback force corresponding to the game content is increased and is difficult to start.
The present invention further provides an electronic device, where the electronic device may be a game pad, a game console, a game operating device, or a mobile terminal device, and the electronic device includes the key structure 100, and the specific structure of the key structure 100 refers to the above embodiments, and since the electronic device adopts all technical solutions of all the above embodiments, the electronic device at least has all beneficial effects brought by all technical solutions of all the above embodiments, and details are not repeated here.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
