In order to realize the control of the electronic device, as shown in fig. 1, the electronic device provided by the present application includes a key structure 10, and the electronic device is controlled by pressing the key structure 10.

In order to control an electronic device by using the key structure 10, in the related art, a key structure 10 is provided, as shown in fig. 2, the key structure 10 includes a key panel 100, a key cap 200, a resilient member 300, a tact switch 400 and a circuit board 500, a channel 110 is formed on the key panel 100, the circuit board 500 is fixed to one side of the key panel 100, the tact switch 400 is disposed on the circuit board 500 and is located in the channel 110, the resilient member 300 is disposed above the tact switch 400, the resilient member 300 is fixed on the circuit board 500, and the key cap 200 is disposed on one side of the resilient member 300 away from the circuit board 500 and is fixedly connected to the resilient member 300.

Through above-mentioned setting, when need be operated dabbing switch 400, press key cap 200 to drive rebound piece 300 downstream, and with dabbing switch 400 butt, make dabbing switch 400 closed, then remove the pressing force of applying on key cap 200, key cap 200 resets under the elastic action of rebound piece 300 this moment, thereby makes dabbing switch 400 disconnection. Thereby achieving the operation of the tact switch 400.

However, in actual mounting, it is necessary to mount resilient member 300 between key cap 200 and tact switch 400, and to fixedly connect resilient member 300 to key cap 200 and circuit board 500, respectively, which complicates the assembly process of key structure 10.

In order to solve the above problem, as shown in fig. 3, the present application provides a key structure 10, which includes a key panel 100, a circuit board 500, a key cap 200 and a tact switch 400, as shown in fig. 4, the key panel 100 includes a plate 120 and an elastic arm 130, the plate 120 is mounted on an electronic device, a channel 110 is formed on the plate 120, and the elastic arm 130 is connected to the plate 120; the circuit board 500 is fixed to one side of the channel 110; as shown in fig. 5, the key cap 200 includes a body 210, a contact arm 220 and a contact plate 230, the body 210 is rotatably connected to the plate 120 and can rotate between a first position and a second position, the contact arm 220 is connected to the body 210, extends into the channel 110, and is located between the body 210 and the circuit board 500, the contact plate 230 is connected to the body 210, extends into the channel 110, and is located between the body 210 and the circuit board 500, an included angle between a rotation axis of the body 210 and a thickness direction of the plate 120 is a, and a is greater than 0 ° and less than or equal to 90 °; the tact switch 400 is disposed between the circuit board 500 and the abutting arm 220, the tact switch 400 is electrically connected to the circuit board 500, the abutting plate 230 abuts against the elastic arm 130 in the case of the first position, the abutting arm 220 abuts against the tact switch 400, and the tact switch 400 is in the closed state, and the tact switch 400 is in the open state in the case of the second position.

Therefore, when the tact switch 400 needs to be closed, the body 210 is pressed, so that the body 210 rotates from the second position to the first position along the first direction, at this time, the abutting arm 220 abuts against the tact switch 400, and the tact switch 400 is in the closed state, and because the abutting plate 230 and the elastic arm 130 are also in the abutting state at this time, after the pressing force is removed, under the effect of the elastic arm 130, the abutting plate 230 can be rebounded, so that the body 210 is driven to rotate from the first position to the second position along the opposite direction of the first direction, and further, the abutting force between the abutting arm 220 and the tact switch 400 is reduced, and the tact switch 400 is in the open state.

Because the on-off of the tact switch 400 is realized by the interaction force between the elastic arm 130 and the abutting plate 230, and the elastic arm 130 is disposed on the plate body 120, i.e. the elastic arm 130 is already manufactured and disposed on the plate body 120 before the assembly, when the key structure 10 is assembled, the body 210 only needs to be rotatably connected to the plate body 120, so that the complexity of the assembly process of the key structure 10 can be reduced.

In addition, since the resilient member 300 is not required to be disposed between the body 210 and the circuit board 500, the consumption of materials can be reduced to a certain extent, and the cost can be reduced.

It can be understood that, when the body 210 is pressed, in order to enable the body 210 to rotate and drive the abutting arm 220 to abut against the tact switch 400, the side of the body 210 where the abutting arm 220 is located should be pressed.

An included angle between the rotation axis of the body 210 and the thickness direction of the plate body 120 is a, where a is greater than 0 ° and less than or equal to 90 °, i.e., a may be any one of angles of 10 °, 20 °, 40 °, 80 °, 90 °, etc., for convenience of design and installation, a =90 °, i.e., the rotation axis of the body 210 is perpendicular to the thickness direction of the plate body 120, and the channel 110 extends along the thickness direction of the plate body 120. Therefore, when the channel 110 is opened, it is convenient, and the installation difficulty of the body 210 during the rotation connection can be reduced in the same rotation connection manner.

In addition, the tact switch 400 may be a short stroke tact switch, that is, the tact switch 400 can be made to respond by pressing a short distance, and the stroke of the short stroke tact switch 400 is generally between 0.3 mm and 0.4 mm. Since the short stroke tact switch has a shorter stroke, the occupied space thereof is also smaller, so that the internal space of the key structure 10 can be reduced.

In this case, in the case of the second position, the abutment arm 220 can be separated from the short stroke tact switch. That is, when the body 210 is not pressed, the contact arm 220 and the short-stroke tact switch are spaced apart from each other, that is, the short-stroke tact switch is not pre-pressed. Therefore, the short-stroke tact switch can be prevented from being pre-pressed, so that the short-stroke tact switch can be prevented from acting when the body 210 is not pressed, and a certain safety space is reserved. Alternatively, the tact switch 400 may be a long-stroke tact switch.

In some embodiments, to effect rotation of the body 210 between the first and second positions, the tact switch 400 can be transitioned between the closed and open states. As shown in fig. 6, the rotation axis of the body 210 is located between the abutment arm 220 and the abutment plate 230; in the first position, the plate surface of the abutment plate 230 on the side away from the rotation axis of the body 210 abuts against the elastic arm 130.

In this way, when the tact switch 400 needs to be closed, as shown in fig. 6, an operator may apply a downward external force (a vertical downward arrow in fig. 6) to a portion of the body 210 on the side where the abutting arm 220 is located, so as to rotate the body 210 along a first direction (a direction represented by a curved arrow in fig. 6), and drive the abutting arm 220 to move downward to abut against the tact switch 400, so as to close the tact switch 400.

Meanwhile, the abutting plate 230 and the elastic arm 130 are abutted together, and at this time, if the tact switch 400 needs to be turned off, as shown in fig. 7, only by removing the external force by the user, under the elastic action of the elastic arm 130, the body 210 rotates around the direction opposite to the first direction (the direction represented by the arrow in fig. 7), and drives the abutting arm 220 to move upward, so that the abutting force between the tact switch 400 and the abutting arm 220 is reduced, and the tact switch 400 is in an off state.

It can be understood that since the tact switch 400 has a certain stroke, that is, when the tact switch 400 is in an off state, the tact switch 400 may be in contact with the abutting arm 220 or may be separated from the abutting arm 220. As long as the tact switch 400 is in the off state.

In addition, as shown in fig. 8, the elastic arm 130 may be disposed on a side wall of the board body 120, and the circuit board 500 is fixed on a side of the elastic arm 130 away from the board body 120. Since the elastic arm 130 is disposed on the sidewall of the plate body 120, there is no obstacle around the elastic arm 130, and when the abutting plate 230 abuts against the elastic arm 130, the deformation of the elastic arm 130 can be facilitated. In this case, in order to prevent the circuit board 500 from affecting the abutment between the abutment plate 230 and the elastic arm 130, the circuit board 500 may be fixed on a side of the elastic arm 130 away from the board body 120.

Alternatively, as shown in fig. 9, the elastic arm 130 may be partially located on the inner wall of the channel 110 and partially located on one side of the plate body 120. Alternatively, the resilient arms 130 may be entirely located on the inner wall of the channel 110.

In addition, in the second position, in order to prevent the body 210 from freely rotating along the rotation axis of the body 210, as shown in fig. 10, in the second position, one side plate surface of the abutting plate 230 away from the rotation axis of the body 210 is in contact with the elastic arm 130.

Through the above arrangement, when the body 210 is at the initial position, that is, when the user does not press the body, the abutting plate 230 is already in a contact state with the elastic arm 130, and the rotation axis of the body 210 is fixed, so the body 210 can be clamped between the elastic arm 130 and the rotation axis of the body 210, and the body 210 can be prevented from rotating along the rotation axis of the body 210 when no external force is applied, thereby ensuring the installation stability of the body 210.

To further enhance the stability, a plate surface of the abutting plate 230 away from the rotation axis of the body 210 may abut against the elastic arm 130, i.e., an interference fit therebetween. In this way, the body 210 is clamped between the elastic arm 130 and the rotation axis of the body, so as to further prevent the body 210 from rotating around the rotation axis, and further improve the installation stability of the body 210.

In addition, in this case, when there is a gap between the contact arm 220 and the tact switch 400, and there is an idle stroke, the contact plate 230 and the elastic arm 130 are in contact with each other, so that the contact arm 220 is not strongly supported in the idle stroke section when the user presses the body 210, and thus the pressing feeling can be enhanced, and the user experience can be improved.

It can be understood that the interference between the abutting plate 230 and the elastic arm 130 can be adjusted, and the interference between the abutting plate 230 and the elastic arm 130 is adjusted to change the resilience of the elastic arm 130 to the abutting plate 230, for example, when the body 210 is pressed, the elastic force of the elastic arm 130 to the abutting plate 230 is greater than 10% -15% of the pressing force of the force applier to the body 210, so that the pressing feeling can be better increased, and the user experience is improved. The selection can be made according to the material of the elastic arm and the requirement of the user.

In other embodiments, the body 210 can be rotated between the first position and the second position to allow the tact switch 400 to transition between the closed and open states. As shown in fig. 11, the rotation axis of the body 210 may be located on the side of the contact plate 230 away from the contact arm 220, and in the first position, the arm surface of the elastic arm 130 close to the body 210 may be brought into contact with the contact plate 230.

With the above arrangement, when the tact switch 400 needs to be closed, as shown in fig. 11, a user may apply a downward external force (vertical downward arrow in fig. 11) to a portion of the body 210 on a side of the abutting arm 220, so as to rotate the body 210 in a first direction (direction represented by curved arrow in fig. 11), and drive the abutting arm 220 to move downward and abut against the tact switch 400, so as to close the tact switch 400.

At the same time, the abutting plate 230 and the elastic arm 130 are abutted together due to the rotation of the body 210. At this time, if the tact switch 400 needs to be turned off, as shown in fig. 12, the user only needs to remove the external force, and under the elastic action of the elastic arm 130, the body 210 rotates around the direction opposite to the first direction (the direction represented by the arrow in fig. 12) and drives the abutting arm 220 to move upward, so that the abutting force between the tact switch 400 and the abutting arm 220 is reduced, and the tact switch 400 is in the off state.

Alternatively, the rotation axis of the body 210 may be located on the side of the abutting arm 220 away from the abutting plate 230. In this case, the movement states of the abutting arm 220, the abutting plate 230 and the tact switch 400 are the same as above, and are not described herein again.

On this basis, to achieve the rotational connection between the bodies 210, as shown in fig. 13, at least a portion of the bodies 210 extends into the channel 110; the key structure 10 further includes a rotating shaft 600 and a rotating hole 610, one of the rotating shaft 600 and the rotating hole 610 is disposed on at least a portion of the body 210, the other of the rotating shaft 600 and the rotating hole 610 is disposed on an inner wall of the channel 110, and the rotating shaft 600 extends into the rotating hole 610; the rotational axis of the body 210 coincides with the axis of the rotary shaft 600.

The rotating shaft 600 is inserted into the rotating hole 610, the rotating shaft 600 can rotate in the rotating hole 610, and when the body 210 is pressed, the body 210 can rotate around the axis of the rotating shaft 600, so that the body 210 can rotate between the first position and the second position.

In this case, in order to realize the installation of the body 210, a downward force may be directly applied to the body 210 from one end of the channel 110 far away from the circuit board 500, under the action of the force, the rotating shaft 600 and the plate body 120 may deform to a certain extent, so that the rotating shaft 600 and the rotating hole 610 may move relatively along the channel 110, and when the rotating shaft 600 moves to a position opposite to the rotating hole 610 and the rotating shaft 600, the rotating shaft 600 may enter the rotating hole 610, thereby realizing the installation. To further facilitate the installation, a guide slope may be provided on the rotation shaft 600, and the rotation shaft 600 may be guided into the rotation hole 610 by the guide slope.

Illustratively, as shown in fig. 14, a rotation hole 610 is formed on at least a portion of the body 210, a rotation shaft 600 is disposed on an inner wall of the channel 110, and the rotation shaft 600 extends into the rotation hole 610, so that the rotation connection between the bodies 210 is realized by the cooperation of the two.

Illustratively, as shown in fig. 15, the rotation hole 610 is opened on the inner wall of the channel 110, the rotation shaft 600 is disposed on at least a portion of the body 210, and the rotation connection between the bodies 210 is realized by cooperation between the two.

In order to increase the stability of the rotation of the body 210, as shown in fig. 16, two rotating shafts 600 and two rotating holes 610 are respectively provided, the rotating shafts 600 and the rotating holes 610 are arranged in a one-to-one correspondence, the rotating shafts 600 extend into the corresponding rotating holes 610, and the axes of the two rotating shafts 600 are collinear. The two rotating shafts 600 and the rotating holes 610 are provided, and the rotating shafts 600 are inserted into the corresponding rotating holes 610, so that the body 210 can be uniformly supported in the axial direction of the rotating shafts 600, and the stable rotation of the body 210 is ensured.

Of course, the rotating shaft 600 and the rotating hole 610 may be provided one by one, and the provision of one rotating shaft 600 and one rotating hole 610 may save raw materials.

In some embodiments, as shown in fig. 17, the key panel 100 further includes a protrusion 700, the protrusion 700 is located on the board body 120 and located on a side of the board body 120 away from the circuit board 500, and the protrusion 700 is disposed around the end of the channel 110; as shown in fig. 18, the body 210 includes a connection plate 240 and a top cover 250, the connection plate 240 extends into the passage 110, and one of the rotation shaft 600 and the rotation hole 610 is provided on the connection plate 240; the top cover 250 is connected with the connecting plate 240 and located on one side of the connecting plate 240 away from the circuit board 500, a gap is formed between the top cover 250 and the board body 120, a groove 251 is formed on one side of the top cover 250 facing the circuit board 500, and the abutting plate 230 and the abutting arm 220 are connected to the groove wall of the groove 251; the projection 700 extends into the groove 251.

Since the groove 251 is formed on the side of the top cover 250 facing the circuit board 500, the protrusion 700 surrounding the channel 110 is formed on the board body 120, and the protrusion 700 extends into the groove 251, when air enters the channel 110 from the end of the channel 110 far from the circuit board 500, the air is blocked by the top cover 250 and the protrusion 700, and during the blocking process, dust adheres to the groove wall of the groove 251 and the protrusion 700, so that the probability of dust entering the channel 110 from the end of the channel 110 far from the circuit board 500 can be reduced, and dust deposition on the circuit board 500 can be avoided.

It can be understood that a gap is provided between the top cover 250 and the plate body 120 to ensure that the gap provides a rotation space for the body 210 when the body 210 is pressed. Therefore, the gap needs to be large enough to ensure that the abutting arm 220 abuts against the tact switch 400 and the tact switch 400 can be in a closed state when the body 210 is pressed.

When the body 210 is pressed, the part of the body 210 on the side of the abutting arm 220 needs to be pressed to make the tact switch 400 in the closed state. Therefore, in order to avoid the pressing error of the user, the user presses the part of the body 210 on the side of the abutting plate 230, as shown in fig. 18, a cushion block 800 is arranged on the surface of the top cover 250 facing the circuit board 500, and the cushion block 800 is located in the gap between the top cover 250 and the board body 120 and is located at the part of the gap on the side close to the abutting plate 230. Therefore, when the user presses the button incorrectly, the body 210 cannot rotate due to the existence of the cushion block 800, and the function of reminding the user can be achieved.

The above description is only an embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions within the technical scope of the present disclosure should be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
