Abstract
The invention relates to a lifting mechanism of a keyboard or a second screen of an electronic device, which comprises a connecting frame, a first rotating shaft, a first driving piece, a linkage piece, a second rotating shaft and a tappet. The first rotating shaft, the first driving piece and the second rotating shaft are rotatably arranged on the combining frame. The first driving member rotates along with the first rotating shaft and is provided with a first driving part. The linkage piece is movably arranged on the combination frame and is provided with a guide sliding groove, and the shape of the guide sliding groove corresponds to the moving path of the linkage piece, wherein the guide sliding groove comprises a lifting surface and a maintaining surface. When the angle of the first rotating shaft is larger than a critical angle, the linkage part does not move along with the rotation of the first rotating shaft. Therefore, the keyboard can be fixed at the optimal ergonomic angle after the main screen is lifted over the critical angle, so as to improve the typing comfort.
Description
Technical Field
The present invention relates to a structural component of an electronic device, and more particularly, to a lifting mechanism for a keyboard or a second screen of a notebook computer.
Background
The keyboard of the traditional notebook computer (hereinafter referred to as pen power) is directly and fixedly arranged on the base, so that when the pen power is placed on a desktop for use, the keyboard is parallel to the desktop and does not form any included angle. However, in terms of ergonomics, the keyboard should be kept at a proper inclination, so that current manufacturers design a power supply with an automatic keyboard lifting mechanism, and when a user lifts the screen, the keyboard is driven by the screen rotating shaft to be automatically lifted to form an inclined shape.
Referring to fig. 15 and 16, the electronic keyboard 91 may be obliquely disposed on the base 92, and a keyboard lifting mechanism (not shown) is disposed below the keyboard 91, such that when the user lifts the screen 93, the rotation shaft of the screen 93 drives the keyboard 91 through the keyboard lifting mechanism and tilts the keyboard 91 relative to the base 92.
Referring to fig. 16 and 17, however, the conventional keyboard lifting mechanism has a disadvantage in that the tilting degree of the keyboard 91 is changed whenever the opening angle of the screen 93 is changed, that is, the keyboard 91 cannot be fixed at an ergonomically optimum tilting angle, and thus the typing comfort is poor.
Specifically, when the user operates the pen, the user needs to tilt the screen 93 to different angles according to the surrounding environmental conditions, such as the height of the desktop or the reflection of light. However, the optimum ergonomic angle (about 7 degrees) of the keyboard 91 is not significantly different due to environmental factors, so that the keyboard 91 is prone to be tilted too much or not sufficiently with the change of the opening angle of the screen 93, and the typing comfort is poor.
Therefore, the keyboard lifting mechanism in the prior art needs to be improved.

Detailed Description
The technical means adopted by the invention to achieve the predetermined creation purpose is further described below by combining the drawings and the preferred embodiments of the invention.
Referring to fig. 1 to 3, the electronic device of the present invention includes a base a1, a lifting mechanism a2, a lifting seat A3, and a main screen a 4. The electronic device is preferably a notebook computer with a keyboard capable of being automatically lifted, or a multi-screen notebook computer with a built-in sub-screen (i.e., a second screen).
In the present embodiment, the base a1 has a main receiving groove a11 and a tappet guide groove a12, the main receiving groove a11 is formed on the top surface of the base a1, and the tappet guide groove a12 is formed on the wall of the main receiving groove a 11.
The lifting seat A3 can be obliquely disposed on the base a1, and the lifting seat A3 of the embodiment is provided with a keyboard, but in other embodiments, a screen can be disposed on the lifting seat A3. Specifically, the lifting seat A3 is disposed in the main receiving groove a11 of the base a1, one side of which is pivoted to the base a1 through the pivot a31, and the other side of which is connected to the lifting mechanism a2, and the inclination of which is controlled by the lifting mechanism a 2.
Referring to fig. 2 to 4, the lifting mechanism a2 includes a connecting frame 10, a first rotating shaft 20, a first driving member 30, a linking member 40, a second rotating shaft 50, and a tappet rod 60; and in the present embodiment, further comprises an intermediate shaft 70 and a second driving member 80.
The above-mentioned combination rack 10 has a lifting seat connecting part 11, which is connected with the lifting seat a 3; the coupling frame 10 is preferably directly connected to the lift pins A3, but may be indirectly connected to the lift pins A3. In the embodiment, the combination rack 10 includes a plurality of plate bodies parallel to each other and spaced apart from each other, the plate bodies include a first plate body 12, a second plate body 13, and a third plate body 14, wherein the second plate body 13 further includes a linking limiting groove 133, and the third plate body 14 further includes a rotation limiting groove 144.
The first shaft 20 is rotatably disposed on the connecting frame 10, one end of the first shaft 20 is a main screen connecting end 21, and the main screen connecting end 21 is connected to the main screen a4 through the connecting member 23. In the present embodiment, a main gear 22 is disposed on the first rotating shaft 20.
Referring to fig. 11 to 14, the middle shaft 70 is rotatably disposed on the connecting frame 10. A pinion 71 is provided on the intermediate shaft 70, the pinion 71 engaging the primary gear 22 of the first shaft 20, thereby rotating the intermediate shaft 70 with the first shaft 20.
The first driving member 30 is rotatably disposed on the coupling frame 10 and rotates with the first rotating shaft 20. Specifically, the first driver 30 is provided on the intermediate rotating shaft 70, and the first driver 30 is rotated along with the first rotating shaft 20 by the meshing of the primary gear 22 and the secondary gear 71, but the intermediate rotating shaft 70 may be omitted, and the first driver 30 may be provided directly on the first rotating shaft 20.
The first driving member 30 has a first driving portion 31. The first drive part 31 is offset from the axis of rotation of the first driver 30, i.e. the first drive part 31 is not located on the axis of rotation of the first driver 30, but in a radial direction of the axis of rotation. When the first driving member 30 rotates, the first driving portion 31 moves along a circle, and a moving path of the first driving portion 31 is defined as a driving path P1 (as shown in fig. 14). In the present embodiment, the first driving member 30 is substantially disc-shaped, and the first driving portion 31 is formed to protrude from one side surface of the first driving member 30 and is cylindrical.
Referring to fig. 4 and 11 to 13, the linking member 40 is movably disposed on the combining frame 10 and has a lifting surface 41, a holding surface 42 and a linking portion 43. In the embodiment, a guiding sliding groove 44 is formed on one side surface of the linking member 40, and the guiding sliding groove 44 is specifically J-shaped. The lifting surface 41 and the maintaining surface 42 are located on one of the two opposite groove walls of the guiding sliding groove 44, but not limited thereto, the lifting surface 41 and the maintaining surface 42 may also be the outer peripheral surface or other outer surfaces of the linking member 40. The linking part 43 is specifically a long groove which is formed on the same side surface of the linking member 40 as the guide sliding groove 44 and preferably extends up and down.
The lifting surface 41 is preferably located in the straight section of the J-shaped guide runner 44. The maintaining surface 42 is connected to one end of the rising surface 41. The maintaining surface 42 is a curved surface and has a shape corresponding to the driving path P1 of the first driving portion 31 of the first driving member 30; that is, the maintaining surface 42 extends along an extension line P2 (shown in fig. 14) in a curved shape, and the extension line P2 corresponds in shape to the driving path P1 of the first driving portion 31 of the first driving member 30.
Referring to fig. 14, the shape of the maintaining surface 42 corresponds to the driving path P1, in this embodiment, the maintaining surface 42 and the driving path P1 are parallel to each other, that is, the driving path P1 and the extension line P2 are parallel to each other. However, the maintaining surface 42 and the driving path P1 are not limited to be completely parallel, and only need to achieve the effect of "making the linking member 40 not move along with the rotation of the first rotating shaft 20" as described below.
More specifically, the driving path P1 is circular and has a single radius of curvature; the holding surface 42 of the present embodiment is a curved surface having a single radius of curvature, and the extension line P2 is a circular arc having a circular arc shape and a single radius of curvature.
The first driving portion 31 of the first driving member 30 slidably penetrates the guide chute 44. The first shaft 20 has a critical angle with respect to the coupling rack 10, and the critical angle is a specific rotation angle of the first shaft 20, which may be an angle value (e.g. 83 degrees) or an angle range (e.g. 80 to 86 degrees) when the coupling rack 10 is used as a reference; the critical angle of the present embodiment is 83 degrees, and corresponds to the main screen a4 being opened to a state close to vertical.
When the rotation angle of the first rotating shaft 20 is smaller than the critical angle (as shown in fig. 11 and 12), the first driving portion 31 of the first driving member 30 abuts against the lifting surface 41 of the linking member 40, and meanwhile, the linking guiding portion 45 abuts against the linking limiting groove 133 of the second plate 13, so that the linking member 40 moves along with the rotation of the first rotating shaft 20. Specifically, the lifting surface 41 is a plane extending vertically, and when the first shaft 20 rotates, the moving path of the first driving portion 31 (i.e., the driving path P1) is circular arc, so that the first driving portion 31 pushes against the lifting surface 41 to move the interlocking member 40.
When the rotation angle of the first rotation shaft 20 is greater than the critical angle (as shown in fig. 14), the first driving portion 31 abuts against the maintaining surface 42 of the linking member 40, and the linking member 40 does not move along with the rotation of the first rotation shaft 20. Specifically, since the extending direction (i.e., the extending line P2) of the maintaining surface 42 is parallel to the moving path (i.e., the driving path P1) of the first driving unit 31, the interlocking member 40 is not moved by the movement of the first driving unit 31 when the first rotating shaft 20 rotates. In addition, since the first driving portion 31 passes through the guiding sliding slot 44, when the angle of the first rotating shaft 20 is larger than the critical angle, the interlocking member 40 is further restricted by another slot wall of the guiding sliding slot 44 and fixed at a specific position relative to the coupling rack 10.
When the rotation angle of the first rotating shaft 20 is greater than the critical angle (as shown in fig. 14), the first driving portion 31 abuts against the maintaining surface 42 of the linking member 40, at this time, the movement of the first driving portion 31 does not move the linking member 40, and then the other end of the second driving portion 81 abuts against the rotation limiting groove 144 of the third plate 14 during the limiting sliding, so that the main screen can still perform the pivoting motion continuously.
The second shaft 50 is rotatably disposed on the coupling frame 10. The second rotating shaft 50 is connected to the linking part 43 of the linking member 40 so that the second rotating shaft 50 rotates along with the movement of the linking member 40, and the specific manner of converting the movement into the rotation is as follows.
The second driving element 80 is disposed on the second shaft 50 and has a second driving portion 81. The second driving portion 81 is offset from the rotation axis of the second driving member 80 and slidably penetrates the interlocking portion 43 of the interlocking member 40. When the linking member 40 is driven by the first shaft 20 to move, the groove wall of the linking portion 43 pushes against the second driving portion 81 to rotate the second shaft 50. In the present embodiment, the second driving member 80 is substantially disc-shaped, and the second driving portion 81 is formed to protrude from one side surface of the second driving member 80 and is cylindrical.
The manner of converting the movement of the linking member 40 into the rotation of the second rotating shaft 50 is not limited to the above, and various conventional structures may be adopted according to circumstances, for example, the linking portion 43 is a rack, and the second rotating shaft 50 is provided with a gear capable of meshing with the rack.
Referring to fig. 2 and 8 to 10, the tappet 60 is disposed on the second rotating shaft 50 and rotates along with the second rotating shaft 50. The opposite ends of the tappet 60 are a proximal end and a distal end, respectively, the proximal end is connected to the second rotating shaft 50, and the distal end extends toward the radial direction of the second rotating shaft 50. The distal end of the tappet 60 abuts downward against the base a1 of the electronic device, and approaches or moves away from the coupling rack 10 as the second rotating shaft 50 rotates. In the present embodiment, the tappet 60 is formed with a tappet limiting portion 61 protruding from the distal end of the tappet 60 and extending in the axial direction of the second rotating shaft 50. The tappet stopper 61 is slidably inserted through the tappet guide groove a12 of the base a1, thereby preventing the distal end of the tappet 60 from being separated from the base a1 of the electronic device.
Referring to fig. 5, 8 and 11, when the main screen a4 of the electronic device is closed, the first driving portion 31 of the first driving member 30 penetrates through the top end of the guiding chute 44 (i.e., the top end of the lifting surface 41). As shown in fig. 12, when the user lifts the main screen a4, the first rotating shaft 20 rotates and rotates the first driving member 30 via the middle rotating shaft 70, so that the first driving portion 31 of the first driving member 30 pushes the lifting surface 41 and the linking member 40 moves.
The first driving part 31 gradually moves downward with respect to the guide chute 44 as the main screen a4 is opened. Referring to fig. 6, 9 and 13, when the main screen a4 is opened to a specific angle, the first driving portion 31 instead abuts against the retaining surface 42 at one end of the lifting surface 41. The critical angle is an angle of the first rotating shaft 20 relative to the coupling rack 10 when the first driving portion 31 is switched from the lifting surface 41 to the maintaining surface 42. In the present embodiment, when the first rotating shaft 20 is at the critical angle (i.e. the state shown in fig. 6, 9 and 13), the angle between the main screen a4 and the base a1 is 83 degrees, and the inclination angle of the lifting seat A3 relative to the base a1 is 7 degrees.
Referring to fig. 7, 10 and 14, when the included angle between the main screen a4 and the base a1 is greater than 83 degrees, the first driving portion 31 abuts against the maintaining surface 42 of the linking member 40. At this time, even if the user adjusts the angle of the main screen a4 (e.g., from 95 degrees to 140 degrees), the tilt angle of the lifting seat A3 with respect to the base a1 does not change with the main screen a4, and is always maintained at 7 degrees.
In summary, the lifting surface 41 and the maintaining surface 42 with different shapes are disposed on the linking member 40, so that when the angle of the first rotating shaft 20 is smaller than the critical angle, the first rotating shaft 20 drives the second rotating shaft 50 and the tappet 60 to rotate through the first driving member 30 and the lifting surface 41 of the linking member 40; when the angle of the first rotating shaft 20 is greater than the critical angle, the moving path of the first driving portion 31 of the first driving member 30 corresponds to the extension line P2 of the maintaining surface 42 of the interlocking member 40, so that the interlocking member 40 is fixed at the same position and does not move when the first rotating shaft 20 rotates, and the second rotating shaft 50 and the tappet 60 are maintained at a fixed angle. In short, by designing the lifting surface 41 and the maintaining surface 42 on the linking member 40, the first rotating shaft 20 can drive the second rotating shaft 50 and the tappet 60 to rotate in an angular range, and simultaneously can fix the second rotating shaft 50 and the tappet 60 in another angular range, so that the keyboard or the sub-screen of the electronic device can be fixed at an ergonomically optimal angle after the main screen is lifted beyond a specific angle without changing the angle with the main screen, and the typing or reading comfort can be improved.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
