Detailed Description
The application provides a rotating shaft device, and this rotating shaft device can give consideration to a plurality of stable formations of using the gesture when obtaining big corner scope, helps satisfying user's user demand better.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 to 18, an embodiment of the present application provides a rotating shaft device, including a first rotating shaft, a second rotating shaft and a control structure assembly, where the first rotating shaft and the second rotating shaft satisfy a parallel condition, that is, the rotating shaft device is a two-shaft hinge structure, and a first connecting member 41 is connected to a base (including a first base 11, a second base 12 and a third base 13, which will be described later) through the first rotating shaft, that is, the first rotating shaft provides relative rotation between the first connecting member 41 and the base; the second link 42 is connected to the base by a second pivot axis, i.e. the second pivot axis provides for relative rotation of the second link 42 and the base. The control structure assembly comprises a first control group and a second control group, wherein the first control group is used for providing a first control point and a second control point, the first control point is used for controlling the first rotating shaft to rotate around the second rotating shaft, namely, the first rotating shaft can be prevented from rotating through the first control point, at the moment, the rotating function of the rotating shaft device can be provided through the second rotating shaft, and therefore, when the second rotating shaft provides rotation, the first rotating shaft rotates around the second rotating shaft; the second control point is used for controlling the second rotating shaft to rotate around the first rotating shaft, namely the second rotating shaft can be prevented from rotating through the second control point, the rotating function of the rotating shaft device can be provided through the first rotating shaft, and therefore the second rotating shaft rotates around the first rotating shaft when the first rotating shaft provides rotation. The second control member group is used for controlling the reciprocating switching between the first control point and the second control point, that is, the second control member group can selectively enable the first control point or the second control point to exert a control function.
The second control group is used for controlling the reciprocating switching between the first control point and the second control point, and comprises switching from the first control point to the second control point and switching from the second control point to the first control point, namely the second control group can provide at least two times of switching in the unidirectional rotation process provided by the rotating shaft device, wherein the unidirectional rotation process refers to rotation towards the same direction without reversing midway, for example, when the rotating shaft device is used for connecting a display part and a main machine part of a notebook computer, the rotation of the display part and the main machine part is opened or closed. Preferably, in the present embodiment, the number of switching times provided by the second control member group in the unidirectional rotation process provided by the rotating shaft device is two, as shown in fig. 14 to 17, in the first posture shown in fig. 14, the first connecting member 41 is at 0 degree with respect to the second connecting member 42, that is, the first connecting member 41 and the second connecting member 42 satisfy the parallel condition, and the first connecting member 41 is located above the second connecting member 42, at this time, the first control point plays a control role, that is, the first rotating shaft does not provide rotation, and in the process of unfolding the rotating shaft device from the first posture to the second state shown in fig. 15, the second rotating shaft provides rotation, and the first connecting member 41 and the base are locked together to rotate around the second rotating shaft by a first angle, for example, 120 ° with respect to the second connecting member 42. In the second posture shown in fig. 15, the second control member group provides the first switching, i.e., the switching from the first control point to the second control point, releases the locking of the first link 41 and the base while allowing the second control point to exert a control action, and then the second rotating shaft does not provide rotation but provides rotation from the first rotating shaft, and during the unfolding of the rotating shaft device from the second posture to the third state shown in fig. 16, the first link 41 rotates relative to the locked first link 41 and the base by a second angle, for example, 160 ° about the first rotating shaft. In the third position shown in fig. 16, the second control member group provides a second switching from the second control point to the first control point, releasing the locking of the second link 42 and the base while allowing the first control point to exert a control action, and then the first pivot does not provide rotation but the second pivot provides rotation, and during the unfolding of the pivot device from the third position to the fourth position shown in fig. 17, the first link 41 and the base are locked together and rotated about the second pivot by a first angle, for example 120 °, with respect to the second link 42. In the fourth posture shown in fig. 17, the first connecting member 41 is 360 degrees relative to the second connecting member 42, that is, the first connecting member 41 and the second connecting member 42 satisfy the parallel condition and the first connecting member 41 is located below the second connecting member 42, that is, the first angle, the second angle and the third angle together form 0 ° to 360 °, that is, the rotating shaft device of the embodiment can provide a complete rotation. Of course, the respective specific values of the first angle, the second angle and the third angle and the rotation angle range formed by the three angles can be flexibly set according to the requirement. Since the second control member group can provide at least two times of switching in the unidirectional rotation process provided by the rotating shaft device, the rotating shaft device provided by the application can divide the whole rotation range into at least three sections, which has the advantage that when the rotation range of the rotating shaft device is required to be 360 degrees, when the rotation angles borne by the first rotating shaft and the second rotating shaft are distributed, for example, the rotation angle borne by the second rotating shaft can be divided into two sections which are separated, and the first section of the two sections can provide the rotation of the rotating shaft device from the first posture of 0 degree to the second posture, and the first section can enable the base to be in the second posture to be not more than 180 degrees relative to the second connecting piece 42. Taking a notebook computer as an example, the first connecting element 41 is connected with the display part, the second connecting element 42 is connected with the host part, the display part and the host part can relatively rotate 360 degrees, when a user uses the notebook computer on a desktop, the second state shown in fig. 15 is mainly used, and because the base is not more than 180 degrees relative to the second connecting element 42 in the second posture, the base can be prevented from hitting the desktop and prying (or supporting) one end of the host part close to the display part. More preferably, the base in the second posture can be slightly less than 180 degrees, for example, 170 degrees, relative to the second connecting member 42, so that while the display portion (the first connecting member 41) of the notebook computer is ensured to be more than 90 degrees relative to the main body portion (the second connecting member 42), the lower end of the display portion is away from the desktop to form a gap, and the gap provides a passage for air emitted from a heat dissipation air opening (located on the side of the main body portion close to the second rotating shaft) of the main body portion, thereby reducing the amount of hot air flowing to the front surface of the display portion and protecting the display screen to a certain extent.
The first control group is configured to provide a first control point and a second control point, and in this embodiment, the first control group includes: a first assembly having a first control point, fixedly connected to the first shaft, for rotation with the first shaft; and the second component is provided with a second control point and is fixedly connected with the second rotating shaft and rotates along with the second rotating shaft. And in the rotation process provided by the rotating shaft device, when the first control point is opposite to the second control point, the second control group controls the first control point and the second control point to be switched. That is to say, the first control point is arranged on the first component rotating along with the first rotating shaft, and the second control point is arranged on the second component rotating along with the second rotating shaft, so that the overall structure of the first control component group is compact, and moreover, because the first control point rotates along with the first rotating shaft and the second control point rotates along with the second rotating shaft, the first control point and the second control point can be opposite in the rotating process provided by the rotating shaft device, and the switching is more rapid and reliable when the first control point and the second control point are opposite. Specifically, in the present embodiment, the first component includes a first cam 21 coaxially disposed with the first rotating shaft, the first control point is an arc depression (i.e., a first slot 211) on the circumferential surface of the first cam 21, the second component includes a second cam 22 coaxially disposed with the second rotating shaft, and the second control point is an arc depression (i.e., a second slot 221) on the circumferential surface of the second cam 22. As shown in fig. 14 to 18, the 0 degree, 120 degree, 280 degree and 360 degree in fig. 18 refer to the angles of the first link 41 relative to the second link 42, and correspond to the first posture shown in fig. 14, the second posture shown in fig. 15, the third posture shown in fig. 16 and the fourth posture shown in fig. 14, respectively, and the arc-shaped recess of the first cam 21 and the arc-shaped recess of the second cam 22 are opposite to each other at 120 degrees and 280 degrees, so that switching is completed once at 120 degrees and 280 degrees, that is, switching from the first control point to the second control point is completed at 120 degrees, and switching from the second control point to the first control point is completed at 280 degrees. It should be noted that the first control point playing a control role in the rotation process of 0 degree to 120 degrees and the first control point playing a control role in the rotation process of 280 degrees to 360 degrees are two cambered concave surfaces on the first cam 21, as shown in fig. 5, the first cam 21 has two first locking grooves 211, and an angle between the two first locking grooves 211 is equal to the second angle, which is 160 ° in this embodiment.
In this embodiment, the first control group includes: and the third assembly is positioned between the first assembly and the second assembly and is used for being locked with the first control point to control the first rotating shaft to rotate around the second rotating shaft and used for being locked with the second control point to control the second rotating shaft to rotate around the first rotating shaft. That is, the third component can be selectively locked with the first control point or the second control point, that is, the first control point and the second control point share the same component to exert a control function, which is beneficial to simplifying the structure of the first control group. Specifically, in this embodiment, the third component is a slider 8, and two ends of the slider 8 have arc protrusions respectively adapted to the first engaging groove 211 and the second engaging groove 221. As shown in fig. 18, the slider 8 is slidably disposed on the first base 11, the slider 8 slides upward to enable the arc protrusion at the upper end of the slider to be clamped into the arc recess of the first cam 21 for locking, and the slider 8 slides downward to enable the arc protrusion at the lower end of the slider to be clamped into the arc recess of the second cam 22 for locking. When the first control point and the second control point are not opposite to each other, that is, when the first control point and the second control point are not rotated to the switchable posture, the arc protrusion of the slider 8 abuts against the peripheral surface of the first cam 21 or the second cam 22 to maintain the current lock, and during the process from 0 degree to 120 degrees, for example, the arc protrusion at the lower end of the slider 8 abuts against the peripheral surface of the second cam 22 to maintain the lock between the slider 8 and the first cam 21.
Further, this embodiment causes the second control group to include: and the unlocking piece is used for driving the third assembly and the first control point to be unlocked in the process that the third assembly and the first control point are locked and rotate around the second rotating shaft together and/or driving the third assembly and the second control point to be unlocked in the process that the third assembly and the second control point are locked and rotate around the first rotating shaft together. That is, the unlocking member can unlock the third component from the first control point and/or the second control point through the rotation process, so that the user can unlock the slider 8 from the first cam 21 and/or the second cam 22 in the process of opening or closing the hinge device, and the electronic device such as a notebook computer using the hinge device is more convenient to use. Preferably, the unlocking piece of the present embodiment includes a first stopping member 6 and a second stopping member 7, and by the cooperation of the first stopping member 6 and the second stopping member 7, the third component is locked with the first control point and rotates around the second rotating shaft together to drive the first rotating shaft to rotate so as to unlock the third component from the first control point, and the third component is locked with the second control point and rotates around the first rotating shaft together to drive the second rotating shaft to rotate so as to unlock the third component from the second control point. The cooperation of the first stop member 6 and the second stop member 7 can provide an accurate physical stop point, that is, when the first stop member 6 abuts against the second stop member 7, the relative position relationship between the first stop member 6 and the second stop member 7 is determined, so that the posture of the spindle device can be accurately reproduced, thereby ensuring that the spindle device completes the unlocking at the preset posture position. Specifically, the present embodiment makes the second control member group include the first gear 3 disposed coaxially with the first rotation axis and fixed relative to the first cam 21, the first stop 6 is a sector gear drivingly connected to the first gear 3 through the idle gear 5, and the second stop 7 is disposed fixedly relative to the second cam 22. As shown in fig. 1 and 2, the second control member group is disposed between the second base 12 and the third base 13, the first gear 3 and the first cam 21 both rotate along with the first rotation shaft, the second stopper 7 and the second cam 22 both rotate along with the second rotation shaft, and when the first gear 3 rotates relative to the base, the first gear 3 drives the sector gear to rotate relative to the base through the idle gear 5.
As shown in fig. 18, the second stopper 7 has a non-circular hole connected to the second rotating shaft to enable the second stopper 7 to rotate with the second rotating shaft after being mounted on the second rotating shaft, the second stopper 7 has a protruding stopper on the circumferential surface, and in the process of 0 degree to 120 degrees, the slider 8 is locked with the first cam 21, so that the first rotating shaft does not provide rotation, i.e. the first gear 3 does not rotate relative to the base, so that the first gear 3, the idler gear 5, the sector gear and the base rotate integrally relative to the second stopper 7 around the second rotating shaft, i.e. the second rotating shaft provides rotation. At 120 deg., the sector gear touches the convex stopper of the second stopper 7, the instant the convex stopper abuts against the sector gear prevents the base from continuing to rotate around the second rotation axis relative to the second stopper 7, and at the same time, the arc depression of the first cam 21 is opposite to the arc depression of the second cam 22, providing a space for the sliding of the slider 8, so as the first connecting member 41 continues to unfold relative to the second connecting member 42, the first rotation axis is driven to rotate so as to drive the first cam 21 and the first gear 3 to rotate relative to the base at the same time, the rotation of the first cam 21 relative to the base forces the slider 8 to slide relative to the base, the slider 8 slides towards the second cam 22 and is locked with it, and the rotation of the first gear 3 relative to the base drives the sector gear to rotate relative to the base. During the subsequent 120 to 280 degrees the second shaft does not provide rotation, i.e. the second stop 7 does not rotate relative to the base, and the first cam 21 and the first gear wheel 3 simultaneously rotate relative to the base, i.e. the first shaft provides rotation. In the process, the sector gear rotates relative to the base and again touches the convex stop of the second stop 7 at 280 degrees, the sector gear is prevented from further rotating relative to the base at the moment the convex stop abuts against the sector gear, the first gear 3 is prevented from further rotating relative to the base by the convex stop since the sector gear is meshed with the idle gear 5 and the idle gear 5 is meshed with the first gear 3, the first cam 21 is prevented from further rotating relative to the base since the first cam 21 and the first gear 3 rotate along with the first rotating shaft, namely the first cam 21 and the first gear 3 are relatively fixedly arranged, and the first cam 21 is prevented from further rotating relative to the base, and at the moment, the cambered surface depression of the first cam 21 is opposite to the cambered surface depression of the second cam 22, so that a space is provided for the sliding of the sliding block 8, and the first gear 3, the idle gear 5 are driven as the first connecting piece 41 is continuously unfolded relative to the second connecting piece 42, The sector gear and the base rotate integrally relative to the second stop 7 around the second rotation axis, and since the second stop 7 is fixedly arranged relative to the second cam 22, that is, the first gear 3, the idler gear 5, the sector gear and the base rotate integrally relative to the second cam 22 around the second rotation axis, the rotation of the second cam 22 relative to the base forces the slide block 8 to slide relative to the base, and the slide block 8 slides towards and is locked with the first cam 21. During the subsequent 280 to 360 degrees the slider 8 is locked with the first cam 21 so that the first axis of rotation is not provided, i.e. the first gear wheel 3 is not rotated relative to the base, so that the first gear wheel 3, the idler wheel 5, the sector gear and the base as a whole are rotated about the second axis of rotation, i.e. the second axis of rotation, relative to the second stop 7. When moving from 360 degrees to 0 degrees, the motion principle is the same as the process motion principle, but the motion direction is opposite, and the description is omitted here.
The present application also provides a rotation method, including:
the first body and the shell of the rotating shaft device form a first locking together to rotate around the second rotating shaft by a first angle through a first control point of a first control point group of the rotating shaft device;
the first body rotates around the first rotating shaft through a second control member group of the rotating shaft device to release the first locking;
the second body and the shell of the rotating shaft device form a second locking through a second control point of the first control piece group and rotate around the first rotating shaft for a second angle together;
the second body enables the second body to rotate around the second rotating shaft through the second control member group to release the second locking;
the first body and the shell of the rotating shaft device form a first locking through a first control point of the first control piece group and rotate around the second rotating shaft for a third angle together.
The rotation method provided by the application realizes the relative rotation of the first body and the second body through the rotating shaft device, firstly, the first body and the shell of the rotating shaft device form locking and rotate around the second rotating shaft, then the first body and the shell of the rotating shaft device are unlocked, the second body and the shell of the rotating shaft device form locking and rotate around the second rotating shaft, then the second body and the shell of the rotating shaft device are unlocked, and the first body and the shell of the rotating shaft device form locking and rotate around the second rotating shaft. The rotating method provided by the application enables the rotating angle born by the second rotating shaft to be divided into two sections (namely, a first angle and a third angle) at intervals, so that when the relative rotating angle of the first body and the second body is more than 180 degrees, the rotating angles born by the first rotating shaft and the second rotating shaft can be better distributed, and the use requirement can be met under the condition that the first angle is set to be a smaller value.
As shown in fig. 14 to 17, in the present embodiment, the first angle, the second angle and the third angle together form 0 ° to 360 °, that is, the first body can rotate once relative to the second body.
