The embodiment of the application provides a mechanical axis body, includes: the device comprises a shell, an elastic body, an operation column, a reset piece, a contact block and a driving part.

The elastic body, the reset piece, the operation column and the driving part are all arranged on the shell, and the operation column can move along the height direction of the mechanical shaft body; the two opposite ends of the reset piece are respectively abutted against the operating column and the shell so as to reset the operating column after moving; the contact block is arranged on the operation column.

The driving part enables the elastic body and the contact block to have a first interval, the operation column is pressed along the height direction of the mechanical shaft body, and the elastic body and the contact block keep the first interval; the driving part generates a second interval between the elastic body and the contact block, and presses the operation column along the height direction of the mechanical shaft body, so that the contact block and the elastic body generate contact collision.

In some embodiments, the mechanical shaft body is in a linear feel state when the elastomer and the contact block are kept at the first interval; when the contact block and the elastic body generate contact collision, the mechanical shaft body is in a hand feeling state of a section.

In this embodiment, in the initial state, the driving portion makes the elastic body and the contact block have a first interval, and at this time, the operation column is pressed downward along the height direction of the mechanical shaft body, and the elastic body and the contact block maintain the first interval, where maintaining the first interval means: the operating column drives the contact block to move downwards, although the distance between the contact block and the elastic body is shortened, the contact block and the elastic body still have an interval therebetween so that the contact block cannot be in contact with the elastic body, at the moment, the operating column moves downwards and cannot make an obvious sound, and then the linear hand feeling state of the mechanical shaft body is realized.

When the mechanical shaft body needs to be switched into a section to feel, the driving part enables the elastic body and the contact block to have a second interval, the operation column is pressed downwards along the height direction of the mechanical shaft body at the moment, the operation column can drive the contact block to be in contact collision with the elastic body, so that a 'clicking' sound is emitted, and the linear hand feeling state of the mechanical shaft body is further realized. The second spacing here means: when the operation column does not move downwards, the driving part enables the elastic body and the contact block to be spaced, and when the operation column moves downwards to drive the contact block to move downwards, the second spacing between the contact block and the elastic body is gradually reduced, and the contact block can be in contact with and collide with the elastic body.

It can be seen from the above that the mechanical shaft body that this application embodiment provided, through setting up the drive division, utilize the drive division adjustment to be in first interval or second interval between contact piece and the elastomer, and when being in first interval between contact piece and the elastomer, contact piece downstream can not contact with the elastomer, and then realize the linear of mechanical shaft body and feel. When the contact block and the elastic body are located at the second interval, the contact block moves downwards and can be in contact collision with the elastic body to make a click sound, and therefore paragraph hand feeling of the mechanical shaft body is achieved.

In some embodiments, in a case where the elastic body has a first interval from the contact block, the driving part moves the elastic body in a first direction to have a second interval from the contact block; the first direction is the height direction of the mechanical shaft body.

In this embodiment, the driving unit moves the elastic body in the height direction of the mechanical shaft body to adjust the first interval between the elastic body and the contact block to the second interval. That is, the driving portion drives the position of the elastic body to change, so that the first interval between the elastic body and the contact block becomes the second interval. Therefore, when the operation column moves downwards, the contact block is driven to move downwards to be in contact collision with the elastic body so as to generate a 'click' sound, and the hand feeling of the mechanical shaft body is realized.

It can be understood that, when the mechanical shaft body needs to be switched from the paragraph hand feeling to the linear hand feeling, the driving portion enables the elastic body to move along the height direction of the mechanical shaft body, so as to adjust the second interval between the elastic body and the contact block by the first interval. When the first interval between the elastic body and the contact block is adjusted to be the second interval, the driving part enables the elastic body to move downwards along the height direction of the mechanical shaft body. When the second interval between the elastic body and the contact block is adjusted to the first interval, the driving part enables the elastic body to move upwards along the height direction of the mechanical shaft body.

In some embodiments, in the case that the elastic body has a first interval with the contact block, the driving part moves the contact block in the second direction to generate a second interval between the elastic body and the contact block; the second direction is a direction around the height direction of the mechanical shaft body.

That is, the driving part drives the position of the contact block to change, so that the first interval between the elastic body and the contact block becomes the second interval. Therefore, when the operation column moves downwards, the contact block is driven to move downwards to be in contact collision with the elastic body so as to generate a 'click' sound, and the hand feeling of the mechanical shaft body is realized.

It can be understood that, when the mechanical shaft body needs to be switched from the paragraph hand feeling to the linear hand feeling, the driving part makes the contact block move along the height direction of the mechanical shaft body, so as to adjust the second interval between the elastic body and the contact block by the first interval. When the first interval between the elastic body and the contact block is adjusted to be the second interval, the driving part enables the contact block to rotate clockwise around the height direction of the mechanical shaft body. When the second interval between the elastic body and the contact block is adjusted to the first interval, the driving part enables the contact block to rotate anticlockwise around the height direction of the mechanical shaft body. Alternatively, when the first interval between the elastic body and the contact block is adjusted to the second interval, the driving unit rotates the contact block counterclockwise around the height direction of the mechanical shaft body. When the second interval between the elastic body and the contact block is adjusted to the first interval, the driving part enables the contact block to rotate clockwise along the height direction of the mechanical shaft body.

The mechanical key 1100B includes a key cap (not shown) and a mechanical shaft body 1110, wherein the key cap covers the mechanical shaft body 1110 as a position directly contacted by a human hand.

The mechanical shaft body 1110 is mounted on the main body 1120 of the keyboard 1100, specifically, the housing 100 of the mechanical shaft body 1110 is connected to the main body 1120 of the keyboard 1100, and the pins of the static contact 500 and the pins of the movable contact 400 are respectively connected to the circuit board 1130 of the keyboard 1100. The directions of the X, Y and Z axes of the mechanical shaft body 1110 are the same as those of a desktop computer.

It should be noted that the terms "top", "upper", "bottom", "lower", "left", "right", "front", and "back" used in the description of the mechanical shaft body 1110 in the embodiments of the present application are mainly explained according to the orientations of the mechanical shaft body 1110 shown in fig. 3 and fig. 4, where the positive direction toward the Z axis is "top", "upper", "the negative direction toward the Z axis is" bottom "," lower "," the positive direction toward the X axis is "right", the negative direction toward the X axis is "left", the positive direction toward the Y axis is "back", and the negative direction toward the Y axis is "front", which do not form a limitation on the orientation of the mechanical shaft body 1110 in the actual application scenario.

The operation column 300 can move along the Z-axis direction, a user presses the keycap, when the operation column 300 moves along the Z-axis negative direction, the operation column 300 can push the movable contact piece 400, the movable contact piece 400 is elastically deformed and then contacts with the static contact piece 500, the movable contact piece 400 and the static contact piece 500 are electrically connected with the circuit board 1130, at the moment, an instruction input by the user can be transmitted to the circuit board 1130 of the keyboard 1100 and then transmitted to the host 1300 through the circuit board 1130 of the keyboard 1100, and after the host 1300 executes corresponding information, the display 1200 displays a final result. It is understood that the action of pressing the operation rod 300 by the user is an input instruction. When the user presses the operating column 300, the resetting piece 600 is compressed, and after the user loosens the operating column 300, the resetting piece 600 resets to drive the operating column 300 to move along the positive direction of the Z axis, so that the operating column 300 resets.

The driving unit 700 has a first gap between the elastic body 200 and the contact block 710, and presses the operation column 300 in the height direction of the mechanical shaft body 1110, thereby maintaining the first gap between the elastic body 200 and the contact block 710. The driving unit 700 generates a second interval between the elastic body 200 and the contact block 710, and presses the operation rod 300 in the height direction of the mechanical shaft body 1110, so that the contact block 710 makes contact and collision with the elastic body 200. To achieve a linear or segmented feel of the mechanical shaft body 1110. When the operating column 300 moves along the negative direction of the Z axis, if the contact block 710 of the operating column 300 can contact with the elastic body 200 to generate a "click" sound, a paragraph hand feeling can be realized; when the contact block 710 of the operating rod 300 moves in the negative Z-axis direction, a linear feel can be achieved if the contact block 710 of the operating rod 300 does not contact the elastic body 200.

In some embodiments, in the initial state, the driving portion makes the elastic body and the contact block have a first interval, and at this time, the operation column is pressed downward along the height direction of the mechanical shaft body, and the elastic body and the contact block maintain the first interval, where maintaining the first interval means: the operating column drives the contact block to move downwards, the distance between the contact block and the elastic body is shortened, but an interval still exists between the contact block and the elastic body, so that the contact block cannot be in contact with the elastic body, at the moment, the operating column moves downwards, no obvious sound is emitted, and the linear hand feeling state of the mechanical shaft body is further realized.

When the mechanical shaft body needs to be switched into a section to feel, the driving portion enables the elastic body and the contact block to have a second interval, the operation column is pressed downwards along the height direction of the mechanical shaft body at the moment, the operation column can drive the contact block to be in contact collision with the elastic body, so that a 'click' sound is emitted, and then the linear hand feeling state of the mechanical shaft body is achieved. The second spacing here means: when the operation column does not move downwards, the driving part enables the elastic body and the contact block to be spaced, and when the operation column moves downwards to drive the contact block to move downwards, the second spacing between the contact block and the elastic body is gradually reduced, and the contact block can be in contact with and collide with the elastic body.

It can be seen from the top that through setting up the drive division, utilize the drive division adjustment to be in first interval or second interval between contact piece and the elastomer, and when being in first interval between contact piece and the elastomer, contact piece downstream can not contact with the elastomer, and then realizes the linear of mechanical axis body and feels. When the contact block and the elastic body are located at the second interval, the contact block moves downwards and can be in contact collision with the elastic body to make a click sound, and therefore paragraph hand feeling of the mechanical shaft body is achieved.

In some embodiments, in the case that the elastic body has a first interval with the contact block, the driving part moves the contact block in a second direction to generate a second interval between the elastic body and the contact block; the second direction is a direction around the height direction of the mechanical shaft body.

The driving unit moves the contact block in a direction around the height direction of the mechanical shaft body to adjust a first interval between the elastic body and the contact block to a second interval. That is, the driving portion drives the position of the contact block to change, so that the first interval between the elastic body and the contact block becomes the second interval. From this, when the control column moves down, drive contact block move down and collide with the elastomer contact in order to send the sound of "clicking", realize that the paragraph of mechanical axis body feels.

In some embodiments, the driving portion is an operation column, and the operation column rotates along the second direction relative to the housing to drive the contact block to move along the second direction.

The operation post is as drive division, can encircle the direction of height rotation of mechanical axis body, and then drives the contact block and remove along the direction of height of mechanical axis body for have the second interval between contact block and the elastomer, and then realize that the paragraph of mechanical axis body feels. It can be understood that when the paragraph is required to be switched to the linear hand feeling, the operation column can be rotated, so that the operation column drives the contact block to move, and further the second interval between the contact block and the elastic body is switched to the first interval, at the moment, when the operation column moves downwards to drive the contact block to move downwards, the contact block cannot be contacted with the elastic body, and the linear hand feeling is realized.

The specific principle of switching linear hand feeling and paragraph hand feeling when the hand feeling state in the paragraph is used as an initial state and the linear hand feeling is needed is as follows: the pressing section 310 of the operating column 300 is rotated to rotate the connecting section 320, so that the first connecting plate 323 faces the first separating plate 150, the contact block 710 is connected to the first connecting plate 323, the elastic body 200 is connected to the first separating plate 150, and the first contact section 220 of the elastic body 200 extends to block (cross along the X direction) the escape opening 151, so that the contact block 710 and the elastic body 200 are located on the same side of the operating column 300 by the rotating operating column 300, the projection of the contact block 710 on the bottom plate 136 of the base 110 and the projection of the elastic body 200 on the bottom plate 136 of the base 110 at least partially coincide in the Z-axis direction, and a second interval is formed between the contact block 710 and the elastic body 200. At this time, the contact block 710 is protruded out of the installation groove 322 and at least partially protruded into the escape groove 127 by the elastic member 720.

When a user applies a downward force to the pressing section 310 of the operation rod 300 through the key cap, the connecting section 320 of the operation rod 300 drives the contact block 710 to move downward away from the avoiding groove 127 and move to the avoiding opening 151, so as to contact with the first contact section 220 of the elastic body 200, and then the pressing force makes the contact block 710 continue to move downward, and the contact block 710 pushes the first contact section 220 of the elastic body 200 and passes over the first contact section 220. After the first contact section 220 is pushed, the first contact section 220 moves downward and drives the spiral section 210 to form a trend of clockwise rotation, the trend of clockwise rotation of the spiral section 210 drives the second contact section 230 to form a trend of leftward movement (X-axis negative direction), but because the second contact section 230 abuts against the fourth side plate 135, the second contact section 230 cannot move leftward, at this time, the trend of leftward movement of the second contact section 230 is converted into a counter-clockwise force, the trend of clockwise rotation of the spiral section 210 is converted into a counterclockwise rotation force, and the counterclockwise rotation force is transmitted to the first contact section 220, so that the first contact section 220 generates an upward counter-clockwise force. The resilience of the first contact segment 220 causes the first contact segment 220 to rebound to the upper side (Y direction) of the contact block 710, and in the process, the contact block 710 pushes against the first contact segment 220 of the elastic body 200 to make a "click" sound, thereby realizing a segment touch.

When the pressing section 310 of the operating column 300 is rotated to rotate the connection section 320 until the second connection plate 324, the third connection plate or the fourth connection plate faces the first partition plate 150, and the first connection plate 323 is staggered from the first partition plate 150, the contact block 710 is connected to the first connection plate 323, and the elastic body 200 is connected to the first partition plate 150, so that the contact block 710 and the elastic body 200 are located on different sides of the operating column 300, at this time, the contact block 710 is retracted into the installation groove 322 under the pressing action of the limiting wall 128 (the inner surface of the second connection plate, the third connection plate or the fourth connection plate), and the projections of the contact block 710 and the elastic body 200 are completely staggered, and a first interval is formed between the contact block 710 and the elastic body 200. When a user applies a downward force to the operation rod 300 through the key cap, the contact block 710 fails to contact the elastic body 200, so that a linear feel is realized.

In either the linear or the paragraph touch state, when the user applies a downward force to the pressing section 310 of the operation rod 300 through the key cap, the guide rod 330 of the operation rod 300 slides downward along the hole wall of the guide hole 171 of the guide cylinder 170 at the same time, and the end of the pressing section 310 of the operation rod 300 presses the reset piece 600, so that the reset piece 600 is compressed. Meanwhile, the pushing block on the outer side wall of the connecting section 320 moves downwards to push the movable contact 400, so that the movable contact 400 is elastically deformed and then contacts with the stationary contact 500, at this time, an instruction input by a user can be transmitted to the circuit board 1130 of the keyboard 1100, and then transmitted to the host 1300 through the circuit board 1130 of the keyboard 1100, and after the host 1300 executes corresponding information, the display 1200 displays a final result. When the user releases the operating rod 300, the reset member 600 is reset, and the pressing section 310 of the operating rod 300 is moved upwards, so that the operating rod 300 is reset.

In this embodiment, the mechanical shaft body 1110 is through setting up contact block 710 on the operation post 300, and set up the operation post 300 and can rotate along guide cylinder 170, when the pressing section 310 of user operation post 300 rotates, make the linkage segment 320 of operation post 300 rotatable, and then make the linkage segment 320 drive contact block 710 and rotate, make contact block 710 can contact or contactless with elastomer 200, switch with the paragraph of realizing mechanical shaft body 1110 feels and linear feel, therefore the user only need purchase a keyboard can, it is very convenient to use, the user purchases the cost reduction of keyboard, and resources are saved.

In another embodiment, referring to fig. 15, fig. 15 is a schematic structural diagram of another mechanical shaft of the keyboard shown in fig. 2. The side wall surfaces of the first connecting plate 323 and the third connecting plate facing away from the guide cavity 321 (the outer surfaces of the first connecting plate 323 and the third connecting plate) are each provided with one of the above-mentioned mounting grooves 322. The number of the contact blocks 710 is two, one of the contact blocks 710 is mounted in the mounting groove 322 of the first connection plate 323, and the other contact block 710 is mounted in the mounting groove 322 of the third connection plate. It can be understood that a contact block 710 is connected to each of the first connecting plate 323 and the third connecting plate, so that the mechanical shaft body 1110 is switched once every 90 degrees of rotation of the connecting section 320.

Specifically, in an initial state (the initial state may be factory setting), the first connection plate 323 faces the first partition plate 150. Since the contact block 710 is connected to the first connection plate 323, the elastic body 200 is connected to the first partition plate 150, and the first contact section 220 of the elastic body 200 extends to block (cross in the X direction) the escape opening 151, the operating column 300 is rotated such that the contact block 710 and the elastic body 200 are located on the same side of the operating column 300. In the Z-axis direction, the projection of the contact block 710 on the bottom plate 136 of the base 110 and the projection of the elastic body 200 on the bottom plate 136 of the base 110 at least partially coincide. At this time, the contact block 710 is protruded out of the installation groove 322 and at least partially protruded into the escape groove 127 by the elastic member 720.

When the connecting section 320 is rotated 90 degrees clockwise, the second connecting plate 324 faces the first separating plate 150, and since the first connecting plate 323 is connected with the contact block 710 and the elastic body 200 is connected to the first separating plate 150, the contact block 710 and the elastic body 200 are located on different sides of the operating column 300, at this time, the contact block 710 is retracted into the mounting groove 322 under the pressing action of the limiting wall 128, and the projections of the contact block 710 and the elastic body 200 are completely staggered. When a user applies a downward force to the operation rod 300 through the key cap, the contact block 710 fails to contact the elastic body 200, so that a linear feeling is realized. When the connecting section 320 continues to rotate clockwise by 90 degrees, the third connecting plate faces the first separating plate 150, and the mechanical shaft body 1110 becomes a hand feeling of a paragraph. Thereby increasing convenience of use.

In other embodiments, in the case that the elastic body has a first interval with the contact block, the driving part moves the elastic body in a first direction to have a second interval with the contact block; the first direction is the height direction of the mechanical shaft body. The drive unit moves the elastic body in the height direction of the mechanical shaft body to adjust the first interval between the elastic body and the contact block to a second interval. That is, the driving part drives the position of the elastic body to change, so that the first interval between the elastic body and the contact block becomes the second interval. Therefore, when the operation column moves downwards, the contact block is driven to move downwards to be in contact collision with the elastic body so as to generate a 'click' sound, and the hand feeling of the mechanical shaft body is realized.

It can be understood that, when the mechanical shaft body needs to be switched from the paragraph hand feeling to the linear hand feeling, the driving part makes the elastic body move along the height direction of the mechanical shaft body, so as to adjust the second interval between the elastic body and the contact block by the first interval. When the first interval between the elastic body and the contact block is adjusted to be the second interval, the driving part enables the elastic body to move downwards along the height direction of the mechanical shaft body. When the second interval between the elastic body and the contact block is adjusted to the first interval, the driving part enables the elastic body to move upwards along the height direction of the mechanical shaft body.

The driving part comprises a switching piece and a positioning piece, the switching piece and the positioning piece are arranged in the shell, and the positioning piece positions the switching piece so that the switching piece can enable the elastic body and the contact block to have a first interval; or the switching piece drives the elastic body to move along the first direction, so that the elastic body and the contact block have a second interval. When the switching piece enables the elastic body and the contact block to have a first interval, the switching piece is positioned by the positioning piece, so that the switching piece is kept still, the relative position between the elastic body and the contact block is prevented from changing, the stable first interval between the elastic body and the contact block is ensured, and the mechanical shaft body has a stable linear hand feeling state. When the mechanical shaft body needs to be switched into a section to feel, the positioning function of the positioning piece on the switching piece is temporarily cancelled, then the switching piece drives the elastic body to move downwards along the height direction of the mechanical shaft body, the positioning piece positions the switching piece after the elastic body is driven to be in place by the switching piece, the switching piece is kept still, and then the elastic body and the contact block are enabled to have a stable second interval, and the mechanical shaft body is enabled to have a stable section hand feeling state.

The switch 740 is slidably coupled to the first cover 122 of the upper housing 120. Specifically, the first cover 122 has a receiving groove 129, two opposite groove walls of the receiving groove 129 have guiding grooves (not shown), two opposite sides of the rod 741 are respectively located in the two guiding grooves, and the switching element 740 slides up and down along the guiding grooves in the receiving groove 129. The operation protrusion 742 is exposed to the outside, and after the upper shell 120 is connected to the base 110, the switch protrusion 743 protrudes from the escape opening 151 into the first cavity 137, and the switch protrusion 743 at least partially overlaps with a projection of the first contact section 220 of the elastic body 200 on the bottom plate 136 of the base 110 along the Z-axis direction.

The first electromagnet 750 is located in the through hole 121 of the upper case 120 and is fixedly connected to a hole wall of the through hole 121. The second electromagnet 760 is disposed in the first chamber 137 of the base 110 and is fixedly connected to the side wall of the first side plate 132 facing the first chamber 137. The electric energy of the first electromagnet 750 and the second electromagnet 760 comes from the circuit board 1130, and specifically, the first electromagnet 750 and the second electromagnet 760 are connected with the circuit board 1130 through wires. Whether the first electromagnet 750 and the second electromagnet are powered on or not can be achieved by combining a control button (not shown) with a single-pole double-throw switch (not shown), specifically, the control button and the single-pole double-throw switch can be arranged on the casing 100, the control button is connected with the single-pole double-throw switch, the control button is arranged outside the casing 100, the single-pole double-throw switch is arranged in the first chamber 137 of the base 110 or the through hole 121 of the upper casing 120, and the single-pole double-throw switch is connected to a wire between the circuit board 1130 and the first electromagnet 750 and the second electromagnet 760.

When the user control button is lifted, the single-pole double-throw switch enables a path between the first electromagnet 750 and the circuit board 1130 to be conducted, so that the first electromagnet 750 is electrified, and the second electromagnet 760 is not electrified. When the user operates the control button to descend, the single-pole double-throw switch makes a path between the second electromagnet 760 and the circuit board 1130 be conductive, so that the first electromagnet 750 is not electrified and the second electromagnet 760 is electrified. The single-pole double-throw button can ensure that only one of the first electromagnet 750 and the second electromagnet 760 is electrified, and the other electromagnet is not electrified, so that the situation that the first electromagnet 750 and the second electromagnet 760 are both electrified or both are not electrified is prevented.

In the second embodiment, the user operates the control button to lift up to energize the first electromagnet 750, the second electromagnet 760 is not energized, and at this time, the first electromagnet 750 generates a first attraction force on the switch projection 743, and the first attraction force attracts the switch projection 743, so that the switch member 740 slides upward along the guide groove in the accommodation groove 129 to move the switch projection 743 away from the first contact section 220 of the elastic body 200, and at this time, the first contact section 220 of the elastic body 200 is located within the stroke range of the contact block 730 of the operation post 300, and a second interval is provided between the contact block 710 and the elastic body 200. When a user applies a downward acting force to the pressing section 310 of the operation column 300 through the keycap, the pressing section 310 of the operation column 300 moves downward to drive the connecting section 320 of the operation column 300 to move downward, the contact block 730 moves downward to the avoiding opening 151 along with the connecting section 320 of the operation column 300 at the same time, and then contacts with the first contact section 220 of the elastic body 200, then the pressing force makes the contact block 730 move downward continuously, and the contact block 730 pushes the first contact section 220 of the elastic body 200 and goes over the first contact section 220. After the first contact section 220 is pushed, the first contact section 220 moves downward and drives the spiral section 210 to form a trend of clockwise rotation, the trend of clockwise rotation of the spiral section 210 drives the second contact section 230 to form a trend of leftward movement (X-axis negative direction), but because the second contact section 230 abuts against the fourth side plate 135, the second contact section 230 cannot move leftward, at this time, the trend of leftward movement of the second contact section 230 is converted into a counter-clockwise force, the trend of clockwise rotation of the spiral section 210 is converted into a counterclockwise rotation force, and the counterclockwise rotation force is transmitted to the first contact section 220, so that the first contact section 220 generates an upward counter-clockwise force. The resilience of the first contact segment 220 causes the first contact segment 220 to rebound to the upper side (Y direction) of the contact block 730, and in the process, the contact block 730 pushes against the first contact segment 220 of the elastic body 200 to make a "click" sound, thereby realizing a segment touch.

Referring to fig. 21 and 22, fig. 21 is a schematic diagram of the mechanical shaft shown in fig. 16 in a state of linear feel, wherein the upper housing is open relative to the base. Fig. 22 is a cross-sectional schematic view of the mechanical shaft body shown in fig. 16 in a linear feel, with the upper housing not shown.

The user controls the button to descend so that the first electromagnet 750 is not energized, the second electromagnet 760 is energized, and the second electromagnet 760 generates a second attraction force on the switch protrusion 743, and the second attraction force attracts the switch protrusion 743, so that the switch member 740 slides downward along the guide slot at the accommodation groove 129, and the switch protrusion 743 pushes the first contact section 220 of the elastic body 200 downward, and the first contact section 220 of the elastic body 200 is located outside the stroke range of the contact block 730, and a first interval is provided between the contact block 710 and the elastic body 200. When a user applies downward acting force to the operation column 300 through the keycap, the pressing section 310 of the operation column 300 moves downward to drive the connecting section 320 of the operation column 300 to move downward, and the contact block 730 moves downward along with the connecting section 320 of the operation column 300 at the same time, but because the first contact section 220 of the elastic body 200 is pushed out of the stroke range of the contact block 730 by the switching protrusion 743, the contact block 730 cannot contact with the first contact section 220 of the elastic body 200 when moving downward, so that linear hand feeling is realized.

Whether linear or sectional, when a user applies a downward force to the pressing section 310 of the operation rod 300 through the key cap, the guide rod 330 of the operation rod 300 slides downward along the hole wall of the guide hole 171 of the guide cylinder 170, and the end of the pressing section 310 of the operation rod 300 presses the reset piece 600, so that the reset piece 600 is compressed. Meanwhile, the pushing block on the outer side wall of the connecting section 320 moves downwards to push the movable contact 400, so that the movable contact 400 is elastically deformed and then contacts with the stationary contact 500, at this time, an instruction input by a user can be transmitted to the circuit board 1130 of the keyboard 1100, and then transmitted to the host 1300 through the circuit board 1130 of the keyboard 1100, and after the host 1300 executes corresponding information, the display 1200 displays a final result. When the user releases the operating rod 300, the reset member 600 resets, and the pressing section 310 of the operating rod 300 is moved upward, so that the operating rod 300 resets.

In other embodiments, whether the first electromagnet 750 and the second electromagnet are energized or not may be implemented by the user operating the operating protrusion 742 of the switch 740 in combination with a single pole double throw switch; specifically, a single-pole double-throw switch and a distance sensor (not shown) may be disposed on the casing 100, the single-pole double-throw switch and the distance sensor are respectively electrically connected to the control module of the circuit board 1130, the single-pole double-throw switch and the distance sensor are disposed in the first chamber 137 of the base 110 or the through hole 121 of the upper case 120, and the single-pole double-throw switch is connected to the wires between the circuit board 1130 and the first and

second electromagnets

750 and 760.

When a user holds the operating protrusion 742 and moves the switching member 740 upward, the distance sensor detects that the distance between the switching protrusion 743 and the first electromagnet 750 is a first distance, the control module of the circuit board 1130 compares the first distance with a preset distance after acquiring the first distance, and if the first distance is smaller than or equal to the preset distance, the control module controls the single-pole double-throw switch to enable a path between the first electromagnet 750 and the circuit board 1130 to be conducted, so that the first electromagnet 750 is powered on, and the second electromagnet 760 is not powered on. When the user holds the operation protrusion 742 with a hand and moves the switching member 740 downward, the distance sensor detects that the distance between the switching protrusion 743 and the second electromagnet 760 is the second distance, the control module of the circuit board 1130 obtains the second distance, compares the second distance with the preset distance, and if the second distance is smaller than or equal to the preset distance, the control module controls the single-pole double-throw switch to conduct the path between the second electromagnet 760 and the circuit board 1130, so that the first electromagnet 750 is not electrified and the second electromagnet 760 is electrified.

The switch 740 includes a rod 741, an operation protrusion 742 and a switch protrusion 743, wherein the operation protrusion 742 and the switch protrusion 743 are respectively fixedly connected to two opposite ends of the rod 741 and located on the same side of the rod 741. The contact block 730 is shaped like a triangle and has an arc-shaped outer surface. The switch pin 770 is shaped like a rectangular parallelepiped, the switch pin 770 includes an upper surface 773 and a lower surface 774 that are disposed along the back of the Z axis, the upper surface 773 of the switch pin 770 is provided with a switching groove 771 that is recessed downward, and a groove bottom wall 772 of the switching groove 771 is inclined with respect to the switch 740.

The switch 740 is slidably coupled to the first cover 122 of the upper housing 120. Specifically, the first cover 122 has a receiving groove 129, two opposite groove walls of the receiving groove 129 have guiding grooves (not shown), two opposite sides of the rod 741 are respectively located in the two guiding grooves, and the switching element 740 slides up and down along the guiding grooves in the receiving groove 129. The operation protrusion 742 is exposed to the outside, and after the upper shell 120 is connected to the base 110, the switch protrusion 743 protrudes into the first cavity 137 from the escape opening 151, and the switch protrusion 743 at least partially overlaps with a projection of the first contact section 220 of the elastic body 200 on the bottom plate 136 of the base 110 along the Z-axis direction.

After the switch 740 is installed in the mounting groove 322, the operation protrusion 742 abuts against the bottom wall 772 of the switch groove 771. When the switch pin 770 slides along the X direction, the operation protrusion 742 always abuts against the bottom wall 772 of the switch groove 771, because the bottom wall 772 is inclined (lower left and higher right), when the switch pin 770 slides leftward, the operation protrusion 742 abuts against the left side of the bottom wall 772 and gradually becomes to abut against the right side of the bottom wall 772, because the right side of the bottom wall 772 is higher, which is equivalent to the operation protrusion 742 being gradually pushed upward along the X direction by the bottom wall 772, so that the switch member 740 moves upward (positive direction of Y axis), after the switch member 740 moves upward, the switch protrusion 743 of the switch member 740 is driven to be away from the first contact section 220 of the elastic body 200, at this time, the first contact section 220 of the elastic body 200 is located in the stroke range of the contact block 730 of the operation column 300, and at this time, a second interval exists between the contact block 710 and the elastic body 200.

When the switch pin 770 slides rightward, the operating protrusion 742 gradually comes into contact with the right side of the bottom wall 772 and gradually comes into contact with the left side of the bottom wall 772, because the left side of the bottom wall 772 is lower, which is equivalent to that the bottom wall 772 is gradually guided and slid downward by the bottom wall 772, so that the switch 740 moves downward, and after the switch 740 moves downward, the switch protrusion 743 of the switch 740 is driven to push the first contact section 220 of the elastic body 200 downward, and at this time, the first contact section 220 of the elastic body 200 is located outside the stroke range of the contact block 730. When a user applies a downward force to the operation rod 300 through the key cap, the operation rod 300 moves downward, and the contact block 730 moves downward together with the operation rod 300, but since the first contact section 220 of the elastic body 200 is pushed out of the stroke range of the contact block 730 by the switching protrusion 743, a first interval is formed between the contact block 710 and the elastic body 200. The contact block 730 cannot contact the first contact section 220 of the elastic body 200 while moving downward, so that a linear feel is achieved.

In the third embodiment, the frictional force between the switch pin 770 and the horizontal plate 122b of the housing positions the switch pin 770. The switch pin 770 has an inclined groove bottom wall, so that when the user operates the switch pin 770 to slide along the direction perpendicular to the Z-axis, the operating protrusion 742 is pushed to move along the Z-axis, so that the switch protrusion 743 pushes the elastic body or loses the pushing force on the elastic body. After the switching protrusion 743 pushes the elastic body out of the stroke range of the contact block, the user releases the switching pin 770, and at this time, the frictional force between the switching pin 770 and the horizontal plate 122b of the first cover 122 makes the switching pin 770 to remain stationary, that is, when no external force is applied, the frictional force between the switching pin 770 and the horizontal plate 122b of the first cover 122 may fix the switching pin 770. When the user operates the switching pin 770 to slide on the horizontal plate 122b of the first cover 122, it is necessary to forcibly overcome the frictional force between the switching pin 770 and the horizontal plate 122b of the first cover 122 so that the switching pin 770 can slide.
