Description

Technical Field

[0001] This invention relates to a keyboard module, and more particularly to a keyboard module that uses magnetic force to control the raising and lowering of keys. Background Technology

[0002] With the advancement of technology, portable electronic products are gradually becoming thinner and more compact. While existing portable computers retain a certain key height, when the screen is closed, the keys protruding from the keyboard frame will come into contact with the screen, causing marks or wear. Besides screen damage, the keycaps may also develop scratches.

[0003] To address these issues, existing portable computers maintain a gap between the screen and the keyboard frame to accommodate the keys and their protruding portions. This, however, hinders the design towards a thinner form factor. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a keyboard module and an electronic device having the keyboard module, which, compared with the prior art, can drive the overall key movement to be completed with a lower driving force, and also has the effect of noise reduction.

[0005] According to one embodiment, a keyboard module includes a substrate, a circuit board, a plurality of keys, a plurality of magnetic components, and at least one link.

[0006] A circuit board is located on a substrate. Multiple buttons are located above the circuit board, each button comprising a keycap, a magnetic element, and a support device. The keycap is located above the circuit board and has a top surface. The magnetic element is located inside the keycap. The support device is located between the keycap and the circuit board, and is used to support the keycap. The number of magnetic components corresponds to the number of magnetic elements, and each magnetic component is located below the substrate and corresponds to a magnetic element. A linkage connects the magnetic components in series. In the descending state, the linkage is rotated by a first force, which drives the magnetic components to rotate, causing each magnetic component to generate an attractive magnetic force with its corresponding magnetic element. The attractive magnetic force drives the keycap to move towards the circuit board.

[0007] According to one embodiment, in the raised state, the connecting rod is rotated by a second force to drive the magnetic components to rotate, so that each magnetic component generates a repulsive magnetic force with its corresponding magnetic element, driving the keycap to move away from the circuit board.

[0008] According to one embodiment, the keyboard module further includes a frame located on a circuit board. The frame has multiple openings, and the keys are disposed within the openings. In a lowered state, the keycaps move to a position where the top surface is at the same height as or lower than the surface of the frame in the vertical direction.

[0009] According to one embodiment, the support device includes a scissor-leg structure and an elastic pad, the scissor-leg structure having an opening and the elastic pad being located within the opening.

[0010] The present invention also proposes an electronic device according to an embodiment, comprising a keyboard module, a connecting device, multiple rotating members, and a rotating shaft device. The keyboard module has multiple connecting rods, each connected in series with a magnetic component, and one end of each connecting rod is defined as a first end. The connecting device is located below the keyboard module and includes a connecting member and multiple sliding blocks. The connecting member includes multiple bodies and multiple movable holes, which are alternately arranged, wherein the first end of each connecting rod is located in each movable hole. Multiple sliding blocks are respectively connected to the bodies. Each rotating member is connected in series with each connecting rod corresponding to each movable hole, and each rotating member includes a rotating part and a pushed part, the rotating part and the pushed part being connected, and each pushed part abutting against a corresponding sliding block. The rotating shaft device is connected to the connecting device, wherein, in a lowered state, the rotating shaft device is used to move the connecting member from a first position to a second position in the horizontal direction, each sliding block pushing against a corresponding pushed part, causing the rotating part to rotate, providing a first force to each connecting rod.

[0011] According to some embodiments, the electronic device further includes an auxiliary moving part, which includes a first magnetic component and a second magnetic component. The first magnetic component is connected to a connector. In the raised state, the first magnetic component and the second magnetic component have a first distance, which is greater than or equal to the distance between a first position and a second position, and the first magnetic component and the second magnetic component have a repulsive force. In the lowered state, the first magnetic component and the second magnetic component have an attractive force, which drives the first magnetic component to move toward the second magnetic component.

[0012] According to some embodiments, the electronic device further includes an auxiliary moving part, which includes a rack and a gear. The rack is connected to a connector. In the raised state, the gear meshes with the rack and has a second distance from the connector. The second distance is greater than or equal to the distance between the first position and the second position. In the lowered state, the gear rolls on the rack, causing the connector to move toward the gear.

[0013] According to some embodiments, the keyboard module includes a frame with a simple structure, which helps manufacturers reduce production costs. According to some embodiments, the keyboard module is applied to electronic devices, such as laptops, to meet their thinness requirements. According to some embodiments, the magnetic force generated by magnetic elements and magnetic components (less than the supporting force of the supporting device, or a repulsive force) allows the user to feel that the keys are stable and do not float when pressed.

[0014] According to some embodiments, the electronic device controls the rotation of the magnetic component by means of a rotating shaft device, a connecting device and a linkage, etc., which further drives the overall button to rise and fall. With this structural design, compared with the prior art, it can be completed with a lower driving force and also has the effect of noise reduction.

[0073] The structural and working principles of the present invention will be described in detail below with reference to the accompanying drawings:

[0074] Please see Figures 1 to 4 , Figure 1 A schematic diagram of the appearance of a keyboard module 1 according to an embodiment of the present invention is shown. Figure 2 A schematic diagram illustrating a button 13 in a raised state according to an embodiment of the present invention is shown. Figure 3 Draw Figure 2 The illustrated embodiment is a schematic diagram in the descent state.

[0075] like Figure 2 and Figure 3As shown, the keyboard module 1 includes a base plate 11, a circuit board 12, a plurality of keys 13, a plurality of magnetic components 14, and a connecting rod 15. The circuit board 12 is located on the base plate 11. The plurality of keys 13 are located above the circuit board 12, and each key 13 includes a keycap 131, a magnetic element 132, and a support device 133. The keycap 131 is located above the circuit board 12, and there is a key travel (i.e., space for the keycap 131 to move up and down) between the keycap 131 and the circuit board 12. The keycap 131 has a top surface 131a and an opposite bottom surface 131b, and the magnetic element 132 is located inside the keycap 131. According to some embodiments, the magnetic element 132 is located on the bottom surface 131b of the keycap 131 (e.g., the magnetic element 132 is adhered to the bottom surface 131b). According to some embodiments, a portion or all of the magnetic element 132 is embedded in the bottom surface 131b (e.g., by injection molding, the magnetic element 132 is embedded in the bottom surface 131b of the keycap 131, so that a portion or surface of the magnetic element 132 is exposed above the bottom surface 131b). A support device 133 is located between the keycap 131 and the circuit board 12. In the raised state, the support device 133 provides a supporting force to support the keycap 131 at a certain height in the vertical direction D1. The support device 133 is elastic; when the keycap 131 is pressed (the force is greater than the supporting force), the support device 133 provides a restoring force to return the keycap 131 to its position. According to some embodiments, the support device 133 includes a scissor-leg structure 1331 and an elastic pad 1332. The scissor-leg structure 1331 has an opening, and the elastic pad 1332 is located within the opening. According to some embodiments, the elastic pad 1332 is made of rubber.

[0076] The number of magnetic components 14 corresponds to the number of magnetic elements 132. Each magnetic component 14 is located below the substrate 11 and corresponds to the magnetic element 132. A connecting rod 15 connects the magnetic components 14 in series. In the descending state, the connecting rod 15 is rotated under force to drive the magnetic components 14 to rotate, so that each magnetic component 14 generates a phase attraction magnetic force with its corresponding magnetic element 132. The phase attraction magnetic force is greater than the supporting force of the supporting device 133, and drives the keycap 131 to move toward the circuit board 12.

[0077] The first force on the connecting rod 15 can be the driving force provided by a connected motor, or it can be the force that drives the connecting rod 15 to rotate through the action of the rotating shaft device 23. The present invention is not limited to this.

[0078] Both the magnetic component 14 and the magnetic element 132 have surfaces with two different magnetic poles, according to Figure 2 and Figure 3 In the embodiment shown, the surface of the magnetic element 132 facing the magnetic component 14 is defined as the attracting surface 1321, and the two surfaces of the magnetic component 14 are defined as the first magnetic surface 141 and the second magnetic surface 142, respectively. Figure 2As shown, in the raised state, the attracted surface 1321 faces downwards in the vertical direction D1 between the first magnetic surface 141 and the second magnetic surface 142. At this time, the magnetic force between the magnetic element 132 and the magnetic component 14 is small, and the supporting force provided by the supporting device 133 is greater than this magnetic force. Therefore, the keycap 131 remains in the raised state. In the lowered state, as... Figure 3 As shown, the connecting rod 15 rotates under a first force, causing the magnetic component 14 to rotate. The first magnetic surface 141 of the magnetic component 14 faces the attracting surface 1321. Since the magnetic poles of the attracting surface 1321 and the first magnetic surface 141 are opposite, an attractive magnetic force is generated between the magnetic element 132 and the magnetic component 14, causing the keycap 131 to move towards the circuit board 12, and the button 13 to retract. This invention does not limit the magnetic poles of the attracting surface 1321 and the first magnetic surface 141. When the attracting surface 1321 is the N pole, the first magnetic surface 141 is the S pole; when the attracting surface 1321 is the S pole, the first magnetic surface 141 is the N pole. According to some embodiments, the connecting rod 15 rotates under a second force, causing the magnetic component 14 to return to its original position. Figure 2 As shown, the keyboard module 1 is in a raised state due to the support of the support device 133.

[0079] Please see Figure 4 This diagram illustrates a key 13 in its raised state according to an embodiment of the present invention. According to this embodiment, the connecting rod 15 rotates under a second force, causing the second magnetic surface 142 of the magnetic component 14 to face the attracting surface 1321 of the magnetic element 132. Since the magnetic poles of the second magnetic surface 142 and the attracting surface 1321 are the same, a repulsive magnetic force is generated between the magnetic component 14 and the magnetic element 132, driving the keycap 131 to move away from the circuit board 12. At this point, the keycap 131 returns to its raised state. The second force can be a driving force provided by a motor, or it can be a force that drives the connecting rod 15 to rotate via a rotating shaft device 23 (which may be the same as or different from the aforementioned rotating shaft device 23). The present invention is not limited to these methods.

[0080] in accordance with Figure 3 and Figure 4 In the illustrated embodiment, the keyboard module 1 further includes a frame 16 located on the circuit board 12. The frame 16 has a plurality of openings 161, the number of which corresponds to the number of keys 13. The keys 13 are disposed within the openings 161. In the lowered state, the keycaps 131 move to a position where the top surface 131a is at the same height as or lower than the surface of the frame 16 in the vertical direction D1. According to some embodiments, when the keyboard module 1 is applied to an electronic device 100, such as a laptop computer, when the screen 4 is closed over the keyboard module 1 (see...), Figure 8When the keyboard module 1 is in the lowered state, the keycaps 131 of the keys 13 move towards the circuit board 12 until the height of the top surface 131a of the keycaps 131 in the vertical direction D1 is equal to or lower than the surface of the frame 16. This prevents the keycaps 131 from scratching the screen 4 and also allows the notebook computer to meet the requirements of thinness. In some embodiments, the frame 16 is the housing 3 of the applied electronic device 100 (see...). Figure 7 Part of ).

[0081] Please see Figure 5 and Figure 6 , Figure 5 A schematic diagram illustrating the relationship between the connecting device 2 and the rotating shaft device 23 in an electronic device 100 according to an embodiment of the present invention is shown. Figure 6 Draw Figure 5 The embodiment shown is a schematic diagram of the relationship between the connecting device 2 and the rotating shaft device 23. Figure 5 and Figure 6 The diagrams represent the interaction between the hinge device 23, the connecting device 2, and the connecting rod 15 in the raised and lowered states of the keyboard module 1, respectively. The base plate 11, the circuit board 12, and the multiple buttons 13 are omitted.

[0082] The electronic device 100 includes a keyboard module 1, a connecting device 2, and a rotating device 23. The keyboard module 1 has multiple connecting rods 15, each of which is connected in series with a portion of the magnetic component 14, and one end of each connecting rod 15 is defined as a first end 151.

[0083] The connecting device 2 is located below the keyboard module 1. The connecting device 2 includes a connector 21 and multiple sliding blocks 26. The connector 21 includes multiple bodies 211 and multiple movable holes 212, which are arranged alternately according to… Figure 5 and Figure 6 In the illustrated embodiment, the first end 151 of the connecting rod 15 is located in the movable hole 212. The movable hole 212 is a slot. In some embodiments, the movable hole 212 is an elongated hole extending along the normal direction of the connecting rod 15. According to some embodiments, the first end 151 of the connecting rod 15 is fixed to a component within the electronic device 100.

[0084] Multiple sliding blocks 26 are respectively connected to the main body 211. A rotating member 22 is connected in series with the connecting rod 15 corresponding to the movable hole 212. The rotating member 22 includes a rotating part 221 and a pushing part 222. The rotating part 221 and the pushing part 222 are connected, and the pushing part 222 abuts against the corresponding sliding block 26, such as... Figure 5 As shown.

[0085] The hinge device 23 is connected to the connecting device 2. According to some embodiments, the hinge device 23 is connected to the screen 4 of the electronic device 100. The screen 4 is pivotally connected to the housing 3. The opening and closing of the screen 4 relative to the housing 3 will drive the hinge device 23 to operate. When the screen 4 is closed relative to the housing 3, the keyboard module 1 is in a lowered state. At this time, the hinge device 23 drives the connecting member 21 to move from the first position P1 to the second position P2 along the horizontal direction D2. The sliding block 26 pushes against the corresponding pushed part 222, driving the rotating part 221 to rotate, providing the first force to the connecting rod 15. In addition to causing the connecting rod 15 to rotate, it also drives the magnetic component 14 to rotate, so that the magnetic element 132 and the magnetic component 14 generate a magnetic attraction force, driving the keycap 131 to move towards the circuit board 12.

[0086] When the screen 4 is opened relative to the housing 3, the keyboard module 1 will be in the raised state again. The pivot device 23 drives the connector 21 to move from the second position P2 to the first position P1 along the horizontal direction D2. The pushed part 222 returns to the state where it is not pushed by the sliding block 26, and the sliding block 26 is in the state of abutting against the pushed part 222. Figure 4 As shown, the pushed part 222 drives the magnetic component 14 to return, and the magnetic force between the magnetic element 132 and the magnetic component 14 is small (see...). Figure 2 ), or it could be due to repulsive magnetic force (see Figure 4 When the attractive magnetic force between the magnetic element 132 and the magnetic component 14 is less than the supporting force provided by the support device 133 to the keycap 131, the keycap 131 returns to its original height in the vertical direction D1 by means of this supporting force. When the magnetic element 132 and the magnetic component 14 generate a repulsive magnetic force, it further assists the support device 133 in supporting the keycap 131, helping the keycap 131 return to its original height in the vertical direction D1. The aforementioned repulsive magnetic force does not affect the user's ability to press the key 13. The magnitude of the supporting force, attractive magnetic force, and repulsive magnetic force depends on the manufacturer's choice of materials and size design, and this invention is not limited thereto.

[0087] Please see Figure 7 and Figure 8 , Figure 7 A schematic diagram illustrating the relationship between the connecting device 2 and the auxiliary moving part in an electronic device 100 according to an embodiment of the present invention is shown. Figure 8 Draw Figure 7The illustrated embodiment shows a schematic diagram of the relationship between the connecting device 2 and the auxiliary moving part. According to this embodiment, the electronic device 100 further includes an auxiliary moving part 24, which includes a first magnetic component 241 and a second magnetic component 242. The first magnetic component 241 is connected to the connecting member 21 and is, for example, disposed between the connecting member 21 and the rotating shaft device 23. The first magnetic component 241 and the second magnetic component 242 have a first distance H1, and the first distance H1 is greater than or equal to the distance between the aforementioned first position P1 and second position P2. The two magnetic poles of the first magnetic component 241 are defined as a first magnetic pole 2411 and a second magnetic pole 2412, and the two magnetic poles of the second magnetic component 242 are defined as a third magnetic pole 2421 and a fourth magnetic pole 2422. According to this embodiment, the second magnetic component 242 can be disposed on another connecting rod 15', which is linked to the rotating shaft device 23.

[0088] like Figure 7 As shown, in the raised state (i.e., the screen 4 is open relative to the housing 3), the first magnetic component 241 and the second magnetic component 242 have a repulsive force, maintaining a first distance H1 between them. That is, in the raised state, the first magnetic pole 2411 faces the third magnetic pole 2421, and the two have the same magnetic poles, thus generating a repulsive force. Figure 8 As shown, in the lowered state (i.e., the screen 4 is closed relative to the housing 3), the other connecting rod 15' is rotated by the pivot device 23, causing the first magnetic pole 2411 to face the fourth magnetic pole 2422. Since the magnetic poles of the first magnetic pole 2411 and the fourth magnetic pole 2422 are opposite, an attraction is generated between them, driving the first magnetic component 241 to move towards the second magnetic component 242. If the screen 4 is opened again relative to the housing 3, the keyboard module 1 will be in the raised state. The other connecting rod 15' is rotated by the pivot device 23, and the other connecting rod 15' rotates the second magnetic component 242 to return to the raised state. Figure 7 The state shown is as follows. With this structural design, the auxiliary moving part 24 can assist the connecting member 21 in moving back and forth between the first position P1 and the second position P2.

[0089] Please see Figure 9 and Figure 10 , Figure 9 A schematic diagram illustrating the relationship between the connecting device 2 and the auxiliary moving part 25 in an electronic device 100 according to an embodiment of the present invention is shown. Figure 10 Draw Figure 9The illustrated embodiment shows a schematic diagram of the relationship between the connecting device 2 and the auxiliary moving part 25. According to this embodiment, the auxiliary moving part 25 includes a rack 251 and a gear 252, with the rack 251 connected to the connector 21. In the raised state (i.e., the screen 4 is open relative to the housing 3), the gear 252 meshes with the rack 251 and has a second distance H2 with the connector 21, the second distance H2 being greater than or equal to the distance between the first position P1 and the second position P2. In the lowered state (i.e., the screen 4 is closed relative to the housing 3), the gear 252 rolls counterclockwise on the rack 251, causing the connector 21 to move toward the gear 252.

[0090] When screen 4 is open relative to housing 3 again, gear 252 rotates clockwise on rack 251, causing connector 21 to move away from gear 252 and return to its original position. Figure 9 The state shown is as follows. With this structural design, the auxiliary moving part 25 can assist the connecting member 21 in moving back and forth between the first position P1 and the second position P2.

[0091] According to some embodiments, there are two rotating shaft devices 23 and connecting devices 2, respectively disposed on opposite sides of the housing 3 (i.e., both ends of the connecting rod 15). There are two rotating parts 22 on the connecting rod 15, respectively located at the first end 151 and the opposite second end (not shown). For the actuation relationship of the rotating shaft device 23, connecting device 2 and connecting rod 15, please refer to the above description.

[0092] According to some embodiments, the keyboard module includes a frame with a simple structure, which helps manufacturers reduce production costs. According to some embodiments, the keyboard module is applied to electronic devices, such as laptops, to meet their thinness requirements. According to some embodiments, the magnetic force generated by magnetic elements and magnetic components (less than the supporting force of the supporting device, or a repulsive force) allows the user to feel that the keys are stable and do not float when pressed.

[0093] According to some embodiments, the electronic device controls the rotation of the magnetic component by means of a rotating shaft device, a connecting device and a linkage, etc., which further drives the overall button to rise and fall. With this structural design, compared with the prior art, it can be completed with a lower driving force and also has the effect of noise reduction.

[0094] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
