The one-way rotation process realizes the reciprocating movement of the functional components, and particularly realizes the reciprocating process of descending the keyboard from ascending to descending in the notebook computer. In the above structure, in order to prevent the rotating member 2 from affecting the sufficient attachment of the first guiding inclined surface 3 and the first matching inclined surface 6, and the second guiding inclined surface 4 and the second matching inclined surface 7 in the rotating process, it is preferable that the four inclined surfaces extend obliquely relative to the axis of the rotating shaft 1, and there is a certain radian in the radial direction of the rotating shaft 1, so that the four inclined surfaces are curved surfaces (curved surfaces of the blades of the fan, for example) which are matched with each other in pairs, and in the rotating process of the rotating member 2, the four inclined surfaces can be attached more tightly and slide relatively more smoothly in pairs.
Compared with the prior art, the driving mechanism has the advantages that the scheme that the functional part can only be driven to move in a single direction in the process of rotating the rotating shaft 1 in a single direction rotation mode, the scheme that the functional part can only be driven to move in a single direction in the process of rotating the rotating shaft 1 in a single direction and the functional part can be pulled to return through the spring can be realized, the reciprocating movement of the functional part can be realized, the working effect and the intelligent degree of electronic equipment are improved, the use of the spring is avoided, the noise is reduced, the occurrence of the spring fracture condition is avoided, the working stability of the driving mechanism is also improved, and the useless work done by the rotating shaft 1 is reduced.
In order to further optimize the technical solution, in the driving mechanism provided in this embodiment, the rotating part 2 is a partial shaft section of the rotating shaft 1, or the rotating part 2 is a cylindrical part sleeved on the rotating shaft 1, or the rotating part 2 is a cylindrical part coaxially connected to an end of the rotating shaft 1. In this embodiment, the matching manner of the rotating member 2 and the rotating shaft 1 in the driving mechanism can be selected from the above-mentioned many options, but in order to improve the working reliability and simplify the structure, it is preferable that the rotating member 2 is a partial shaft section of the rotating shaft 1, that is, the end of the rotating shaft 1 is processed to become the rotating member 2, and the sliding member 5 is slidably sleeved on the rotating member.
As shown in fig. 1 to 3, the slider 5 includes: a shaft sleeve 51 slidably fitted over the rotary member 2 to allow the sliding member 5 to reciprocate in the axial direction of the rotary shaft 1; and two convex matching projections 52 which are convexly arranged on two end surfaces of the shaft sleeve 51, wherein the side walls of the two convex matching projections 52 are respectively a first matching inclined surface 6 and a second matching inclined surface 7. Meanwhile, as shown in fig. 1 to 3, it is preferable that the rotation member 2 includes: the body 21 is sleeved with the shaft sleeve 51; a plurality of guide protrusions 22 provided on the outer circumferential wall of the body 21, located at both ends of the body 21, and protruding the outer circumferential wall; the guiding protrusions 22 located at the same end of the body 21 and adjacently arranged define a guiding groove 23 allowing the mating protrusion 52 to slide in, and the side wall of the guiding groove 23 is the first guiding inclined surface 3 or the second guiding inclined surface 4. The sliding member 5 and the rotating member 2, which are constructed as described above, are provided with specific structures to ensure operational reliability and simplify the structure, while ensuring normal operation, because the installation space in the electronic apparatus is limited.
In addition, the guide projection 22 of the rotation member 2 is formed as an integral structure with the body 21, and the guide projection 22 and the guide groove 23 are formed by notching the circumferential outer wall of the rotation member 2 at the time of processing.
Of course, the rotating member 2 and the sliding member 5 can be matched by other structures, for example, the sleeve 51 can be replaced by a spiral guide rail arranged on the body 21 and extending around the axis of the body 21, and a sliding block arranged on the spiral guide rail in a sliding manner, the sliding block is connected with the two matching projections 52, when the rotating member 2 rotates, the sliding block slides on the spiral guide rail, but the track of the sliding rail is a straight line parallel to the axis of the rotating shaft 1, and the two matching projections 52 are connected on the spiral guide rail and are symmetrically arranged around the perpendicular line of the axis of the rotating member, i.e. the matching projections 52 are arranged and configured in the same manner as the matching projections 52 in the former structure (i.e. the structure with the sleeve 51). This configuration also satisfies the requirements of the engagement of the rotor 2 and the slider 5.
Preferably, the guiding groove 23 is an isosceles triangle groove or an isosceles trapezoid groove, and the matching protrusion 52 is an isosceles triangle protrusion or an isosceles trapezoid protrusion capable of being spliced with the guiding groove 23, as shown in fig. 1 to 3. In this arrangement, two opposite side walls of the guiding groove 23 are symmetrical, that is, the two guiding grooves 23 not only have the first guiding inclined surface 3 and the second guiding inclined surface 4, but also have the third guiding inclined surface symmetrical to the first guiding inclined surface 3 and the fourth guiding inclined surface symmetrical to the second guiding inclined surface 4, the first guiding inclined surface 3 and the third guiding inclined surface enclose one guiding groove, the second guiding inclined surface 4 and the fourth guiding inclined surface enclose another guiding groove, similarly, two inclined surfaces of the matching protrusion 52 opposite to the rotating member 2 in the circumferential direction are symmetrical, that is, the two matching protrusions 52 not only have the first matching inclined surface 6 and the second matching inclined surface 7, but also have the third matching inclined surface symmetrical to the first matching inclined surface 6 and the fourth matching inclined surface symmetrical to the second matching inclined surface 7, wherein, the first engagement inclined surface 6 and the third engagement inclined surface belong to the same engagement projection 52, and the second engagement inclined surface 7 and the fourth engagement inclined surface belong to the other engagement projection 52, so that the rotation member 2 and the sliding member 5 can be reversely engaged, that is, the aforementioned process of descending to ascending to descending of the keyboard can be completed in the process of opening the notebook computer, or during the clockwise (or counterclockwise) rotation of the shaft 1, while when closing the notebook computer, when making pivot 1 anticlockwise (also can be clockwise) rotate promptly, can realize the keyboard again by the cooperation of third direction inclined plane and third cooperation inclined plane, the cooperation of fourth direction inclined plane and fourth cooperation inclined plane, make the reciprocal lift of keyboard can all be realized to the in-process that opens and shuts to the keyboard by descending to rise again.
In addition, the guide groove 23 and the matching convex block 52 in the structure can also enable the rotating part 2 and the sliding part 5 to be better clamped, ensure that the first guide inclined plane 3 and the first matching inclined plane 6, the second guide inclined plane 4 and the second matching inclined plane 7 are better and fully attached, and improve the working reliability of the driving mechanism.
In the present embodiment, it is also preferable that the side wall is the guide groove 23 of the second guide slope 4, and the length of the bottom wall thereof in the circumferential direction of the rotating shaft 1 is larger than the length of the end face of the fitting projection 52 (this end face refers to the wall face parallel to the end face of the boss 51 on the end of the fitting projection 52 away from the boss 51). That is, the guide groove 23 of the second guide slope 4 is formed on one end of the rotating member 2, and the bottom wall of the guide groove extends in the circumferential direction of the rotating shaft 1 to a length greater than that of the end face of the engaging protrusion 52, so that when the first engaging slope 6 is pushed by the first guide slope 3 and separated from the first guide slope 3, that is, the sliding member 5 moves from the guide groove 23 on one end of the rotating member 2 to the guide groove 23 on the other end, since the length of the bottom wall is greater than that of the end face, when the sliding member 5 moves into the other guide groove 23, the second engaging slope 7 of the sliding member 5 is not yet engaged with the second guide slope 4, and there is a gap therebetween, so that the sliding member 5 does not move in the axial direction during the next rotation of the rotating member 2, and the rotating member 2 rotates only in the circumferential direction relative to the sliding member 5, therefore, the rotating shaft 1 can not drive the sliding part 5 to move within a certain rotating angle, and particularly in a notebook computer, the keyboard can not be driven to move when the included angle between two parts of the notebook computer is changed within the range of 120-240 degrees, so that the keyboard is always kept at a rising position. When the second guiding inclined surface 4 of the rotating member 2 rotates to the position where the second matching inclined surface 7 stays, the two guiding inclined surfaces are attached to each other and push the sliding member 5 to move in the opposite direction along with the continuous rotation of the rotating member 2, and at the moment, the included angle between the two parts of the notebook computer exceeds 240 degrees, so that the keyboard of the notebook computer is lowered in the process of converting to the flat plate shape. In this arrangement, in consideration of the fact that the notebook computer is in the notebook form, the included angle between the screen component and the host portion (i.e., the portion provided with the keyboard) needs to be adjusted according to the sitting postures and heights of different users, and in this process, if the keyboard descends under the cooperation of the second guide inclined surface 4 and the second matching inclined surface 7, the normal use of the notebook computer is affected, so that through the arrangement of the structure, the notebook computer has a certain range of free opening and closing angles, the working performance of the notebook computer can be enabled, and the influence on the arrangement of the driving mechanism provided by the embodiment can be avoided.
Further preferably, the matching projection 52 and the shaft sleeve 51 are of an integral structure; the guide projection 22 and the body 21 are of an integral structure. The sliding part 5 and the rotating part 2 which are integrally structured are convenient to process and have higher self rigidity, so that the driving mechanism provided by the embodiment has longer service life.
Based on the above driving mechanism, the present embodiment further provides an electronic device, which includes a keyboard frame (not shown in the drawings) for carrying a keyboard and a driving mechanism for driving the keyboard frame to move up and down, the driving mechanism is the above driving mechanism, and preferably, the electronic device is a notebook computer.
In particular, the keyboard frame is connected to the slide 5 by a link 8, as shown in fig. 1-3. In this embodiment, the component for driving the keyboard frame and the sliding member 5 is preferably a relatively simple and small-sized link 8, so as to better adapt to a small installation environment inside the electronic device.
In the present specification, the structures of the respective portions are described in a progressive manner, and the structure of each portion is mainly described as being different from the existing structure, and the whole and partial structures of the driving mechanism can be obtained by combining the structures of the plurality of portions.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
