Description

Key and keyboard

Technical Field

The application relates to the field of mechanical structures, in particular to a key and a keyboard.

Background

The key types of the mechanical keyboard are mainly classified into mechanical axis keys, optical axis keys, magnetic axis keys, capacitance axis keys and the like. Mechanical axis keys are the most commonly used type at present. The mechanical shaft key has different types of shaft body types such as green shaft, tea shaft, black shaft, white shaft and the like aiming at different paragraph sense, feedback and knocking sound. These shaft types are most largely categorized as having paragraphs and no paragraphs. When a user needs to switch the mechanical keyboard with the section sense to the mechanical keyboard without the section sense, the corresponding mechanical shaft keys need to be replaced, and the process of replacing the mechanical shaft keys is very complicated.

Disclosure of Invention

The application provides a button and keyboard, when being convenient for not changing the mechanical axis button, can make the button have the paragraph to feel and do not have the paragraph to feel two kinds of states and switch.

A first aspect of the embodiments of the present application provides a key, including a housing, a shaft, an elastic member, and a lever. The shell is provided with a containing cavity. The shaft body comprises a guide column part and a protruding part, wherein the guide column part is at least partially accommodated in the accommodating cavity, the protruding part is connected with the guide column part, and the guide column part drives the protruding part to move relative to the shell along the pressing direction when moving relative to the shell along the pressing direction. The elastic piece comprises a first torsion arm and a second torsion arm, wherein the first torsion arm is fixedly connected with the shell, and the second torsion arm is provided with a contact part. The driving lever comprises a lever body and a rotating part, wherein the lever body is rotatably connected with the shell through the rotating part, and a first rotating arm and a second rotating arm are formed on two sides of the rotating part. The first rotating arm extends out of the shell, and the second rotating arm is arranged in the accommodating cavity and used for contacting the elastic piece. When the first rotating arm rotates around the rotating part to the first position, the second rotating arm acts on the elastic piece in the first state. When the second rotating arm rotates around the rotating part to the second position, the second rotating arm acts on the elastic piece in the second state. When the elastic piece is in the first state, the projection of the contact part is positioned in the projection of the convex part on the projection plane perpendicular to the pressing direction. When the elastic piece is in the second state, the projection of the contact part is positioned outside the projection of the convex part on the projection plane perpendicular to the pressing direction.

The push button is driven by the shift lever to move the elastic member so that the projection of the contact portion is located inside or outside the projection of the projection on the projection plane perpendicular to the pressing direction. When the projection of the contact part is positioned in the projection of the bulge, the bulge can contact the contact part along the pressing direction, so that the contact part of the elastic piece is driven to elastically move, and the section sense of the pressing shaft body is formed. When the projection of the contact part is positioned outside the projection of the bulge, the bulge does not contact the contact part when moving along the pressing direction, and the movement of the shaft body along the pressing part is not elastically acted by the elastic piece, so that the shaft body does not have paragraph feeling. The push button is provided with a first rotating arm and a second rotating arm in a rotating mode, and the relative length of the first rotating arm and the second rotating arm is adjusted, so that the force applied to the first rotating arm and the driving stroke of the first rotating arm can be adjusted. When the keyboard using the key needs light and thin processing, the length ratio of the first rotating arm and the second rotating arm can be reduced, so that less driving stroke is applied to the first rotating arm, namely, the contact part of the second rotating arm has larger stroke, and the contact part is driven to move a longer distance. When the keyboard using the key has only a low-power driving piece, the length ratio of the first rotating arm to the second rotating arm can be increased, so that less driving force is applied to the first rotating arm, and the contact part of the second rotating arm can drive the contact part to move.

Based on the first aspect, in one possible implementation manner, the key further includes a rebound member, one end of the rebound member acts on the shaft body, and the other end acts on the housing for moving the driving shaft in a direction opposite to the pressing direction relative to the housing.

In this possible embodiment, after the shaft body is moved in the pressing direction by applying a pressing force to the shaft body, if the pressing force is reduced, the shaft body can be returned in the opposite direction of the pressing direction by the spring-back member.

Based on the first aspect, in one possible implementation manner, the elastic member includes a first torsion arm and a second torsion arm that are elastically matched, and the first torsion arm acts on the housing, and the contact portion is located on the second torsion arm. The second torsion arm can elastically move relative to the first torsion arm so that the elastic piece is restored to the first state from the second state.

In this possible implementation, when the elastic member is in a torsion spring structure, there is a first torsion arm and a second torsion arm that are elastically matched, and when the first torsion arm acts on the housing, the second torsion arm can elastically deform relative to the housing. When the contact portion is triggered by the projection moving in the pressing direction, the contact portion applies an elastic force to the projection so as to have a soft paragraph. The first torsion arm and the second torsion arm can also realize automatic recovery to the first state, and the transition from the second state to the first state can be realized only by releasing the thrust from the first state to the second state without additional driving force.

Based on the first aspect, in one possible implementation manner, the first rotating arm and the second rotating arm are disposed at an acute angle.

In this possible implementation, the first and second rotating arms are at an acute angle, which may further limit the space occupation of the lever.

Based on the first aspect, in one possible implementation manner, a portion of the second rotating arm for contacting the elastic member forms a force application surface, and when the second rotating arm rotates around the rotating portion to the second position, the force application surface is parallel to the pressing direction.

In this possible implementation manner, when the second rotating arm rotates to the second position, the elastic member is driven to enter the second state, and at this time, the elastic member has a tendency to return to the first state, and the probability of the elastic member accidentally returning to the first state can be reduced by the force application surface being parallel to the pressing direction.

Based on the first aspect, in one possible implementation manner, the housing is provided with a mounting opening, and the first rotating arm extends out of the housing through the mounting opening. The mounting opening is provided with a limiting piece, and the limiting piece is used for limiting the first rotating arm at a first position or a second position.

In this possible implementation manner, the position of the shift lever can be limited to a certain extent by arranging the limiting piece, and when the shift lever is limited, the elastic force of the elastic piece can be reduced to drive the shift lever to move, so that the shift lever is difficult to position the elastic piece to the first state or the second state.

Based on the first aspect, in one possible implementation manner, the limiting piece includes a deformable bump extending from an inner wall of the mounting hole, and the mounting hole forms a first split and a second split on two sides of the deformable bump. The first opening is used for accommodating the first rotating arm at the first position, and the deformable lug limits the first rotating arm at the first position to move to the second position. The second opening is used for accommodating the first rotating arm at the second position, and the deformable lug limits the first rotating arm at the second position to move to the first position.

In this possible implementation, the deformable tab deforms when a sufficient force is received to form a gap that allows the first rotating arm to move between the first position and the second position, and a sufficient force is required to rotate the first rotating arm to cause the deformable tab to rotate the first rotating arm between the first position and the second position. When the sufficient force is greater than the force of the resilient member to switch between the first state and the second state, the resilient member alone is insufficient to drive the lever. Thereby improving the stability of the position of the deflector rod relative to the shell.

Based on the first aspect, in one possible implementation manner, the housing includes a first housing portion and a second housing portion, the first housing portion is detachably connected with the second housing portion, and the accommodating cavity is formed between the first housing portion and the second housing portion.

In this possible embodiment, the difficulty of assembling the shaft body with the housing can be reduced by the detachable first housing part and the second housing part.

A second aspect of embodiments of the present application provides a keyboard comprising a frame, a driving structure and one or more keys provided in any implementation manner of the first aspect. The first rotating arm extends out of the shell to form a force receiving part. The frame is fixedly connected with the shell of one or more keys. The driving structure is connected with the frame, and the driving structure is connected with the stress part of one or more keys and is used for driving the first rotating arm to move between a first position and a second position.

The keyboard drives the first rotating arms of the plurality of keys to move at the first position and the second position through the driving structure, and can enable the keys on the keyboard to contact with the contact part or not contact with the contact part when pressing the shaft body, so that the keyboard comprises two modes of paragraph feeling and non-paragraph feeling when pressing the shaft body.

Based on the second aspect, in one possible implementation manner, the driving structure includes a first driving member and a driving rod. The first driving piece is connected with the frame, and the output end of the first driving piece is connected with the driving rod so as to drive the driving rod to move parallel to the pressing direction. The driving rod is connected with the stress part of the key in a locking manner in the pressing direction.

In this possible implementation manner, the driving rod is matched with the stress parts of the keys, so that the driving rod can drive the stress parts to move, and when the driving rod is matched with the stress parts of the plurality of keys, the same driving rod can drive the plurality of stress parts to move.

Based on the second aspect, in one possible implementation manner, the driving rod has a limiting hole, the limiting hole has a first inner surface and a second inner surface opposite along the pressing direction, and the stress portion of the key is located between the first inner surface and the second inner surface.

In this possible implementation, the form of the limiting hole is provided by the driving rod, and only the stressed part of the key needs to be inserted into the limiting hole.

Based on the second aspect, in one possible implementation manner, the driving structure includes an electromagnet, the electromagnet has a first magnetic surface facing the force-receiving portion, and the force-receiving portion has a second magnetic surface facing the electromagnet. The first rotating arm is driven to move between the first position and the second position through the attraction or repulsion of the magnetism of the first magnetic surface and the second magnetic surface.

In this possible implementation manner, the magnetism of the force-receiving part is changed by the electromagnet to realize magnetic attraction or magnetic repulsion, so as to drive the force-receiving part to move.

Based on the third aspect, in one possible implementation manner, the driving structure includes a second driving member and a roller, the roller is provided with a cam guiding surface corresponding to the stress portion, and the second driving member is used for driving the roller to roll, so that different positions of the cam guiding surface act on the stress portion.

In this possible embodiment, the rotation of the cam is converted into a translation of the force-receiving part by means of the form of the cam, so that the force-receiving part of the pushbutton arranged in the axial direction of the roller is moved.

Based on the third aspect, in one possible implementation manner, the driving structure further includes a reset element, where one end of the reset element acts on the housing or the frame, and the other end acts on the stress portion. The reset piece is used for applying elastic force close to the cam guide surface to the force receiving part.

In this possible embodiment, the restoring element can make the force-receiving portion stably engage the cam guide surface, so that the force-receiving portion moves along the changing direction of the cam guide surface.

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Fig. 1 shows a schematic structural diagram of a keyboard 001 in one embodiment of the present application. Fig. 2 is a schematic diagram showing a partial internal structure of a keyboard 001 in one embodiment of the present application.

As shown in fig. 1 and 2, the keyboard 001 includes a frame 030, a driving structure 050, and a plurality of keys 010. Both the key 010 and the driving structure 050 are connected to the frame 030. The fixing of the relative positions of the plurality of keys 010 is achieved by the frame 030. Based on the pressing feeling of the key 010, the key 010 has a paragraph feeling state and a no paragraph feeling state. The driving structure 050 is used for driving the key 010 to switch between a paragraph sense state and a no paragraph sense state.

Fig. 3 shows a schematic structural diagram of a key 010 in an embodiment of the present application. Fig. 4 shows a schematic structural view of the key 010 in an embodiment of the present application, the first rotating arm 511 is located at the first position, and the first housing part 110 is removed. Fig. 5 shows an exploded schematic view of a key 010 in an embodiment of the present application. Fig. 6 shows a schematic structural view of the key 010 in an embodiment of the present application, the first rotating arm 511 is located at the second position, and the first housing part 110 is removed.

As shown in fig. 3, such a key 010 includes a housing 100 and a shaft 200. The shaft 200 is partially located within the housing 100. Referring to fig. 4 and 5 in combination, the housing 100 has a receiving chamber 101, and the receiving chamber 101 has an opening at one end in the pressing direction X. The shaft body 200 includes a guide pillar portion 210, where a part of the guide pillar portion 210 is located in the accommodating cavity 101, and one end of the guide pillar portion protrudes from the accommodating cavity 101 through the opening. The shaft body 200 is slidably coupled to the housing 100 such that the shaft body 200 can move parallel to the pressing direction X with respect to the housing 100. The outer circumference of the shaft body 200 contacts the inner wall of the opening, which may guide the movement direction of the shaft body 200, thereby reducing the probability that the direction of movement of the shaft body 200 with respect to the housing 100 deviates from the pressing direction X.

The housing 100 includes a first housing portion 110 and a second housing portion 130. The first and second shell portions 110 and 130 are arranged along the pressing direction X. The receiving cavity 101 is formed between the first and second shell portions 110 and 130. When the shaft body 200 is assembled with the housing 100, the first and second housing portions 110 and 130 may be separated, one end of the guide pillar portion 210 may be extended from the first housing portion 110, and then the first and second housing portions 110 and 130 may be connected such that a portion of the guide pillar portion 210 is accommodated in the accommodating cavity 101 between the first and second housing portions 110 and 130.

The key 010 further comprises a rebound member 300. One end of the rebound member 300 acts on the shaft body 200, and the other end acts on the housing 100. The rebound member 300 may store elastic potential energy when the shaft body 200 moves in the pressing direction X. When the elastic potential energy is released from the elastic member 300, the elastic member 300 may move the driving shaft body 200 in the opposite direction of the pressing direction X. Optionally, the resilient member 300 is a compression spring. The extension direction of the compression spring is parallel to the pressing direction X. When the shaft body 200 is moved in the pressing direction X by the pressing force, the compression spring is compressed in the pressing direction X, thereby storing elastic potential energy. When the pressing force on the shaft body 200 is reduced, the compression spring releases elastic potential energy so that the shaft body 200 moves in the opposite direction of the pressing direction X.

The key 010 further comprises an elastic member 400. The elastic member 400 is connected to the housing 100 and disposed in the accommodating cavity 101. The elastic member 400 has a contact portion 451, and the contact portion 451 is elastically movable with respect to the housing 100. The elastic movement finger contact portion 451 can be elastically restored to the pre-relative movement position by itself of the elastic member 400 after movement relative to the housing 100. The shaft body 200 further includes a protrusion 230. The protruding portion 230 is fixedly connected to the guide pillar portion 210, and when the guide pillar portion 210 moves in the pressing direction X relative to the housing 100, the protruding portion 230 also moves in the pressing direction X relative to the housing 100. The protrusion 230 is adapted to cooperate with the contact portion 451 such that the key 010 creates a feeling of a paragraph. Specifically, when the user presses the shaft body 200, so that the protruding portion 230 and the guide pillar portion 210 move along the pressing direction X relative to the housing 100, if the protruding portion 230 contacts the contact portion 451, the contact portion 451 feeds back an elastic force to the protruding portion 230, and the elastic force makes the user pressing the shaft body 200 feel a change in force, so as to generate a paragraph sense. If the contact portion 451 is also capable of performing a movement of a predetermined path according to the outer shape of the protrusion 230, and the contact portion 451 is separated from the protrusion 230 after the protrusion 230 moves a certain stroke in the pressing direction X, the user is also capable of feeling the abrupt disappearance of the elastic force, further enhancing the feeling of the paragraph.

The key 010 further comprises a lever 500. The lever 500 includes a lever body 510 and a rotating portion 530. The rotating portion 530 is a cylindrical bump, a cylindrical groove is disposed in the accommodating cavity 101 of the housing 100, and the cylindrical bump is accommodated in the cylindrical groove, so that the lever 500 is rotatably connected with the housing 100, and an axis of rotation of the lever 500 and the housing 100 is an axis of the rotating portion 530.

Referring to fig. 4 and 6 in combination, the lever 500 forms a first rotating arm 511 and a second rotating arm 513 at both sides of the rotating part 530. When the lever body 510 rotates around the rotating part 530, the first rotating arm 511 and the second rotating arm 513 have the same angular velocity. The first rotating arm 511 extends out of the housing 100 to form a force receiving portion 5111, and the lever 500 can be driven to rotate around the rotating portion 530 by applying an external force to the force receiving portion 5111. The second rotating arm 513 is provided corresponding to the contact portion 451. When the force receiving portion 5111 receives an external force to rotate the first rotating arm 511 to the first position, the second rotating arm 513 acts on the elastic member 400, so that the elastic member 400 is in the first state. When the force receiving portion 5111 receives an external force to rotate the first rotating arm 511 to the second position, the second rotating arm 513 acts on the elastic member 400, so that the elastic member 400 is in the second state. Wherein the first state of the elastic member 400 corresponds to the paragraph feeling state of the key 010, and the second state of the elastic member 400 corresponds to the no paragraph feeling state of the key 010.

When the elastic member 400 is in the first state, on a projection plane perpendicular to the pressing direction X, the projection of the contact portion 451 is located within the projection of the projection 230. At this time, the protrusion 230 is able to contact the contact portion 451 when moving in the pressing direction X, so that the elastic force of the contact portion 451 acts on the shaft body 200 and is fed back to the user.

When the elastic member 400 is in the second state, the projection of the contact portion 451 is located outside the projection of the projection 230 on the projection plane perpendicular to the pressing direction X. At this time, when the protrusion 230 moves in the pressing direction X, the contact portion 451 is not contacted, so that a user does not receive feedback of a paragraph feeling caused by the contact of the contact portion 451 with the protrusion 230 in the process of pressing the shaft body 200.

The elastic member 400 is a torsion spring. Spring 400 includes a body portion 410, a first torsion arm 430, and a second torsion arm 450. First torsion arm 430 and second torsion arm 450 are disposed about body portion 410. The accommodating chamber 101 has a mounting groove. The first torsion arm 430 is disposed in the mounting groove and acts on the housing 100 such that the first torsion arm 430 is difficult to move relative to the housing 100. The contact portion 451 is located on the second torsion arm 450, and when the second torsion arm 450 receives an external force, the first torsion arm 430 acts on the housing 100 to be stationary with respect to the housing 100, and the second torsion arm 450 and the housing 100 generate a relative movement to cause the elastic member 400 to deform. The body portion 410 of the resilient member 400 and the second torsion arm 450 themselves exert a resilient force such that the second torsion arm 450 has a tendency to return to a pre-movement position relative to the housing 100. When the protrusion 230 acts on the contact portion 451 of the second torsion arm 450, such that the second torsion arm 450 moves relative to the housing 100, the elastic force generated by the main body portion 410 and the second torsion arm 450 can enable the contact portion 451 of the second torsion arm 450 to feedback the elastic force to the protrusion 230, so that the user receives the feedback of the paragraph sense. The protrusion 230 has a first face 231 and a second face 233 opposite in the pressing direction X. The first surface 231 is inclined to the pressing direction X, and the second surface 233 is also inclined to the pressing direction X. For ease of description, an imaginary separating plane is defined, which is perpendicular to the pressing direction X, with the first plane 231 and the second plane 233 being located on both sides of the separating plane. When the protrusion 230 contacts the contact portion 451 and continues to move in the pressing direction X, the first face 231 guides the movement of the contact portion 451 such that the contact portion 451 also has a movement perpendicular to the pressing direction X away from the guide pillar portion 210. After the first face 231 guides the contact portion 451 to displace to the edge of the first face 231, the contact portion 451 is separated from the first face 231 and corresponds to the second face 233. The force of the contact portion 451 acting on the protrusion 230 is a force in the opposite direction to the pressing direction X when the contact portion 451 corresponds to the first surface 231, but the force of the contact portion 451 acting on the protrusion 230 is a force in the pressing direction X when the contact portion 451 corresponds to the second surface 233, so that when the contact portion 451 changes from acting on the first surface 231 to acting on the second surface 233, a user can significantly feel a force change when pressing the shaft body 200, and a more pronounced paragraph feeling is generated.

It will be appreciated that in other embodiments, the resilient member 400 may be a spring having one end secured to the housing 100 and the other end defining the contact portion 451. The reed itself may also be elastically deformed to act on the protrusion 230 to provide a user with a paragraph feedback.

Alternatively, the first rotating arm 511 and the second rotating arm 513 of such a lever 500 are disposed at an acute angle, so that the first rotating arm 511 and the second rotating arm 513 occupy a small space. When the second rotating arm 513 is substantially parallel to the pressing direction X, the first rotating arm 511 can have a smaller extension in the direction perpendicular to the pressing direction X, so that the key 010 occupies less space perpendicular to the pressing direction X.

The second rotating arm 513 has a biasing surface 5131. When the first rotating arm 511 rotates between the first position and the second position, the second rotating arm 513 contacts the elastic member 400 through the biasing surface 5131 to control the elastic member 400 to switch between the first state and the second state. When the second rotating arm 513 rotates to the second position about the rotating portion 530, the urging surface 5131 is parallel to the pressing direction X. When the second rotating arm 513 rotates to the second position, the elastic member 400 is driven to enter the second state, and at this time, the elastic member 400 has a tendency to return to the first state, and the force application surface 5131 is parallel to the pressing direction X, so that the probability of the elastic member 400 accidentally returning to the first state can be reduced.

The housing 100 is provided with a mounting opening 150, and the first swing arm 511 extends out of the housing 100 through the mounting opening 150. A gap is also provided between the first rotation arm 511 and the inner wall of the mounting port 150 in the pressing direction X, so that the rotation arm can move in the mounting port 150, thereby driving the lever body 510 of the lever 730 to rotate around the rotation portion 530.

A stopper is provided in the mounting port 150. The limiter may limit the movement of the first rotating arm 511 from the first position to the second position when the first rotating arm 511 is located at the first position. The limiter may limit the first rotation member from moving from the second position to the first position when the first rotation arm 511 is located at the second position. The stop includes a deformable tab 170. The deformable projection 170 extends from the inner wall of the mounting port 150 into the mounting port 150. The deformable projection 170 divides the mounting port 150 into a first split 151 and a second split 153 distributed in the pressing direction X.

When the first rotating arm 511 is located at the first position, the first rotating arm 511 is accommodated in the first sub-opening 151, and the deformable protrusion 170 contacts one end of the first rotating arm 511 near the second sub-opening 153. The deformable protrusion 170 can limit the movement of the first rotating arm 511 toward the second split 153. When the external force acting on the first rotating arm 511 is sufficiently large, the first rotating arm 511 transmits the external force to the deformable protrusion 170, and the deformable protrusion 170 is sufficiently deformed so that there is enough space between the first and second sub-ports 151 and 153 for the first rotating arm 511 to move, the first rotating arm 511 can move from the first sub-port 151 into the second sub-port 153, and at this time, the first rotating arm 511 moves from the first position to the second position.

When the first rotating arm 511 is located at the second position, the first rotating arm 511 is accommodated in the second sub-opening 153, and the deformable protrusion 170 contacts one end of the first rotating arm 511 near the first sub-opening 151. The deformable protrusion 170 can restrict the movement of the first rotating arm 511 toward the first split 151. When the external force acting on the first rotating arm 511 is sufficiently large, the first rotating arm 511 transmits the external force to the deformable protrusion 170, and the deformable protrusion 170 is sufficiently deformed so that there is enough space between the second slit 153 and the first slit 151 to allow the first rotating arm 511 to move, the first rotating arm 511 can move from the second slit 153 into the first slit 151, and at this time, the first rotating arm 511 moves from the second position to the first position.

The deformable protrusion 170 restricts the movement of the first rotating arm 511 between the first position and the second position, i.e., restricts the movement of the second rotating arm 513, corresponding to the synchronous movement of the first rotating arm 511 and the second rotating arm 513, so as to restrict the transition of the elastic member 400 between the first state and the second state. It is necessary to apply a sufficient external force to the first rotating arm 511 to switch the elastic member 400 between the first state and the second state, so that the probability of the elastic member 400 accidentally switching states can be reduced.

It is understood that the deformable tab 170 may be integrally formed with the housing 100. Or may be made of a different material from the housing 100, and then fixedly connected to the housing 100, for example, made of a rubber material.

Fig. 7 shows a cross-sectional view taken along VII-VII in fig. 3, with the first swing arm 511 in a first position. Fig. 8 shows a cross-sectional view of the keyboard 001 in one embodiment of the present application, the cross-sectional view being the same as fig. 7, but with the first swing arm 511 in the second position.

Referring to fig. 7 and 8, the method for using the key 010 from the state without paragraph feeling to the state with paragraph feeling includes:

s101, driving the first rotating arm 511 so that the first rotating arm 511 moves from the second position to the first position, and the second torsion arm 450 is abutted against the second rotating arm 513 and moves following the second rotating arm 513 due to the elastic force of the elastic member 400, so that the elastic member 400 enters the first state from the second state;

s102, pressing the shaft body 200 so that the protrusion 230 moves toward the contact portion 451;

s103, the protruding part 230 contacts the contact part 451, and the contact part 451 is deformed, the contact part 451 generates elastic force and acts on the protruding part 230, and then the elastic force is transferred to the guide pillar 210 to generate paragraph feeling;

s104, the contact portion 451 moves along the first surface 231 until the contact portion 451 is separated from the first surface 231 and acts on the second surface 233, and the force of the contact portion 451 acting on the protrusion 230 is reversed, so that the shaft body 200 generates a more obvious paragraph feel than the step S103;

s105, the shaft body 200 is no longer pressed in the pressing direction X, and the resilient member 300 releases elastic potential energy so that the shaft body 200 moves in a direction opposite to the pressing direction X, in which process, since the second surface 233 is inclined to the pressing direction X, the contact portion 451 can be guided to have a movement amount perpendicular to the pressing direction X to be separated from the second surface 233 and correspond to the first surface 231, and finally the contact portion 451 is separated from the first surface 231.

The method for using the key 010 from the paragraph sense state to the no paragraph sense state comprises the following steps:

s201, driving the first rotating arm 511 so that the first rotating arm 511 moves from the first position to the second position, and the second torsion arm 450 moves due to the driving of the second rotating arm 513 so that the elastic member 400 enters the second state from the first state;

s202, pressing the shaft body 200 so that the protrusion 230 moves toward the contact portion 451, in which process the protrusion 230 of the shaft body 200 does not contact the contact portion 451, thus not producing a feeling of a paragraph;

s203, the shaft body 200 is no longer pressed along the pressing direction X, and the resilient member 300 releases the elastic potential energy to move the shaft body 200 in the direction opposite to the pressing direction X.

It can be understood that such a key 010 is a process of releasing elastic potential energy to restore the shape when the elastic member 400 is moved from the second state to the first state, and a process of moving the elastic member 400 from the first state to the second state is a process of driving the elastic member 400 to deform by the second rotating portion 530. In other embodiments, the key 010 may be configured such that the elastic member 400 enters the first state from the second state as the second rotating portion 530 drives the elastic member 400 to deform, and the elastic member 400 enters the second state from the first state as the process of releasing elastic potential energy to restore the shape.

As shown in fig. 2, such a drive structure 050 includes a first drive 710 and a drive rod 730. The first driver 710 includes a motor. The motor is fixedly connected with the frame 030 of the keyboard 001. The motor has an output that is connected to a drive rod 730. The motor may be coupled to the first driving member 710 in a form in which a gear is engaged with a rack. A gear is disposed at the output end of the motor, a rack is disposed at one side of the driving rod 730, and the rotation of the output end of the motor can be the translation of the driving rod 730. The driving lever 730 is connected to the force receiving portions 5111 of the plurality of keys 010 arranged at intervals in the arrangement direction Y. The arrangement direction Y is perpendicular to the pressing direction X. When the driving lever 730 moves, the force receiving portions 5111 of the plurality of keys 010 connected to the driving lever 730 are driven to move together. So that the first rotating arm 511 of the plurality of keys 010 simultaneously moves between the first position and the second position.

The driving lever 730 has a limiting hole 731. The limiting holes 731 extend in the arrangement direction Y. The force receiving portions 5111 of the plurality of keys 010 are inserted into the limiting holes 731. The limiting hole 731 has a first inner surface 7311 and a second inner surface 7313 opposite in the pressing direction X. When the motor moves the driving lever 730 in the pressing direction X, the first inner surface 7311 of the driving lever 730 acts on the force receiving portion 5111 of the plurality of keys 010 to drive the first rotating arm 511 of the plurality of cases to move from the first position to the second position. When the motor moves the driving lever 730 in the pressing direction X, the second inner surface 7313 of the driving lever 730 acts on the force receiving portion 5111 of the plurality of keys 010 to drive the first rotating arm 511 of the plurality of cases to move from the second position to the first position.

It is understood that the force receiving portions 5111 of the plurality of keys 010 may be fixedly connected to the driving rod 730 by means of gluing or the like. As long as the force receiving portion 5111 can be lockingly connected with the driving lever 730 in the pressing direction X, so that when the driving lever 730 moves parallel to the pressing direction X, the force receiving portion 5111 can follow the driving lever 730 to move parallel to the pressing direction X.

Fig. 9 is a schematic diagram showing a partial internal structure of a keyboard 001 in one embodiment of the present application.

As shown in fig. 9, such a drive structure 050 includes an electromagnet 750. The electromagnet 750 is fixedly connected to the frame 030 of the keyboard 001. The electromagnet 750 has a first magnetic surface 751 facing the plurality of force receiving portions 5111, and the first magnetic surface 751 is capable of changing the magnetic pole. The force receiving portion 5111 is a permanent magnet, and the force receiving portion 5111 has a second magnetic surface 5113 facing the electromagnet 750. The electromagnet 750 is controlled to magnetically attract or magnetically repel the force receiving portion 5111 by controlling the first magnetic surface 751.

The electromagnet 750 is disposed on an extension line of the force receiving portion 5111 from the second position to the first position. If the second magnetic surface 5113 is an S pole, the first magnetic surface 751 is controlled to be an N pole, so that the electromagnet 750 magnetically attracts the force receiving portion 5111, thereby driving the force receiving portion 5111 to move from the second position to the first position. The electromagnet 750 and the force receiving portion 5111 are magnetically repelled by controlling the first magnetic surface 751 to be the S pole, so as to drive the force receiving portion 5111 to move from the first position to the second position.

Fig. 10 is a schematic diagram showing a partial internal structure of a keyboard 001 in one embodiment of the present application.

As shown in fig. 10, such a driving structure 050 includes a second driving member 770 and a roller 790. The second driver 770 includes a motor. The motor is fixedly connected with the frame 030 of the keyboard 001. The motor has an output end, and the output end is fixedly connected with the roller 790.

The plurality of keys 010 are arranged at intervals along the arrangement direction Y. The roller 790 is provided with a cam guide surface 791. The cam guide surface 791 contacts the force receiving portions 5111 of the plurality of keys 010. When the second driver 770 drives the roller 790 to rotate, the force receiving portion 5111 slides along the surface of the cam guide surface 791, and the cam guide surface 791 may guide the first rotating arm 511 to move from the first position to the second position.

The drive structure 050 also includes a reset element. The return member may be a compression spring. Frame 030 includes extension bars. The extension rod and the roller 790 are disposed opposite to each other along the pressing direction X, and the force receiving portion 5111 is located between the extension rod and the roller 790. One end of the restoring member acts on the extension rod and the other end acts on the force receiving portion 5111, and the restoring member is used for applying an elastic force to the force receiving portion 5111 near the cam guiding face 791. After the driving roller 790 rotates to enable the cam guiding surface 791 to guide the first rotating arm 511 to move from the first position to the second position, the driving roller 790 is driven to rotate, and the restoring member can enable the stress portion 5111 to be attached to the cam guiding surface 791 and return to the first position from the second position. It will be appreciated that, since the frame 030 is fixedly connected to the housing 100 of the key 010, the restoring member may be configured such that one end acts on the housing 100 and the other end acts on the force receiving portion 5111, and the elastic force near the cam guiding surface 791 can be applied to the force receiving portion 5111.

It will be appreciated that another roller 790 may be used to drive the first rotary arm 511 from the second position back to the first position. Two rollers 790 are disposed on both sides of the force receiving portion 5111 in the pressing direction X. The cam guide surface 791 of one of the rollers 790 is for driving the force receiving portion 5111 from the first position to the second position, and the cam guide surface 791 of the other roller 790 is for driving the force receiving portion 5111 from the second position to the first position.

It can be understood that the driving structure 050 is connected to the force receiving portions 5111 of the plurality of keys 010 at the same time, so as to realize simultaneous driving of the force receiving portions 5111 of the plurality of keys 010, and may be connected to the force receiving portion 5111 of only one key 010, so as to drive the force receiving portion 5111 of only one key 010.

The keys 010 of such a keyboard 001 drive the elastic member 400 to move through the lever 500 such that the projection of the contact portion 451 is located inside or outside the projection of the protrusion 230 on the projection plane perpendicular to the pressing direction X. When the projection of the contact portion 451 is located within the projection of the protrusion 230, the protrusion 230 moves in the pressing direction X to contact the contact portion 451, thereby driving the contact portion 451 of the elastic member 400 to elastically move, forming a sectional sense of the pressing shaft body 200. When the projection of the contact portion 451 is located outside the projection of the protrusion 230, the protrusion 230 does not contact the contact portion 451 when moving in the pressing direction X, and the movement of the shaft body 200 along the pressing portion is not elastically affected by the elastic member 400, without having a feeling of a paragraph. The push button 010 is adjusted to have a sense of paragraph by the push button 500, and the push button 500 is provided with the first rotary arm 511 and the second rotary arm 513 in a rotary manner, and the relative length of the first rotary arm 511 and the second rotary arm 513 is adjusted, so that the force applied to the first rotary arm 511 and the driving stroke of the first rotary arm 511 can be adjusted. When the keyboard 001 using such a key 010 requires a light and thin process, the length ratio of the first rotating arm 511 and the second rotating arm 513 can be reduced, so that a smaller driving stroke is applied to the first rotating arm 511, i.e., the contact portion 451 of the second rotating arm 513 can be made to have a larger stroke, thereby driving the contact portion 451 to move a longer distance. When the keyboard 001 using such a key 010 has only a low-power driving member, the length ratio of the first rotating arm 511 and the second rotating arm 513 can be increased, so that less driving force is applied to the first rotating arm 511, and the contact portion 451 of the second rotating arm 513 can be caused to move by the contact portion 451. The driving structure 050 can simultaneously drive the force receiving portions 5111 of the plurality of keys 010, thereby realizing state transition of the plurality of keys 010.

The foregoing is merely a specific embodiment of the present application, but the protection 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 in the scope of the disclosure of the present application.
