Detailed Description
The application provides a rotating shaft device, which can be used for stabilizing a plurality of using postures while obtaining a large rotating angle range, and is beneficial to better meeting the using requirements of users.
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1 to 18, an embodiment of the present application provides a rotating shaft device, which includes a first rotating shaft, a second rotating shaft, and a control structure assembly, wherein the first rotating shaft and the second rotating shaft satisfy a parallel condition, that is, the rotating shaft device is of a double-shaft hinge structure, and a first connecting member 41 is connected with a base (including a first base 11, a second base 12, and a third base 13 described later) through the first rotating shaft, that is, the first rotating shaft provides relative rotation of the first connecting member 41 and the base; the second connector 42 is coupled to the base by a second shaft, i.e., the second shaft provides relative rotation of the second connector 42 and the base. The control structure assembly comprises a first control element group and a second control element group, wherein the first control element 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 not provide rotation through the first control point, at the moment, the rotation function of the rotating shaft device can be provided through the second rotating shaft, and therefore the first rotating shaft rotates around the second rotating shaft when the second rotating shaft provides rotation; the second control point is used for controlling the second rotating shaft to rotate around the first rotating shaft, namely the second control point can realize that the second rotating shaft does not rotate, at the moment, 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 rotates. The second control element group is used for controlling the reciprocating switching between the first control point and the second control point, that is, the second control element group can selectively enable the first control point or the second control point to exert a control effect, preferably, in the rotation process provided by the rotating shaft device, one of the first control point and the second control point must exert a control effect at the same moment, that is, only one of the first rotating shaft and the second rotating shaft provides rotation at the same moment, and the other one does not provide rotation.
The second control element 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 also comprises switching from the second control point to the first control point, namely the second control element 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 in the same direction without midway reversing, for example, when the rotating shaft device is used for connecting a display part and a host part of a notebook computer, the rotation opening process of the display part and the host part is adopted, or the rotation folding process is adopted. Preferably, in this embodiment, the number of times of switching provided by the second control member group during the unidirectional rotation provided by the rotation shaft device is made to be two, as shown in fig. 14 to 17, in the first posture shown in fig. 14, the first connecting member 41 is at 0 ° 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 above the second connecting member 42, at which time the first control point plays a control role, that is, the first rotation shaft does not provide rotation, and in the process of unfolding the rotation shaft device from the first posture to the second state shown in fig. 15, rotation is provided by the second rotation shaft, the first connecting member 41 and the base are locked together to rotate around the second rotation shaft by a first angle, for example, 120 °. In the second position shown in fig. 15, the second control member set provides a first switch, i.e. from the first control point to the second control point, releasing the locking of the first link 41 and the base while allowing the second control point to exert a control action, after which the second spindle provides no rotation but rotation by the first spindle, the spindle arrangement being unfolded from the second position to the third position shown in fig. 16, the first link 41 being rotated by a second angle, e.g. 160 °, about the first spindle with respect to the first link 41 and the base locked together. In the third position shown in fig. 16, the second control member set provides a second switch, i.e. from the second control point to the first control point, releasing the locking of the second connection member 42 and the base while allowing the first control point to exert control action, after which the first rotation axis provides no rotation but rotation by the second rotation axis, and the rotation axis device is unfolded from the third position to the fourth position shown in fig. 17, the first connection member 41 and the base are locked together to rotate around the second rotation axis by a first angle, e.g. 120 °. In the fourth posture shown in fig. 17, the first connecting member 41 is 360 degrees 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 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 present embodiment can provide a full rotation. Of course, the specific values of the first angle, the second angle and the third angle and the angle range formed by the three angles can be flexibly set according to the requirement. Since the second control member set is capable of providing at least two shifts during the unidirectional rotation provided by the spindle means, the spindle means provided by the present application may divide its overall rotation range into at least three segments, which has the advantage that when a 360 ° rotatable range of the spindle means is required, the rotation angle assumed by the first spindle and the second spindle may be divided into two segments at intervals, for example, when the rotation angle assumed by the second spindle is allocated, and thus the first segment of the two segments provides a rotation of the spindle means from a first position of 0 degrees to a second position, which first segment may allow the base to assume a position of not more than 180 degrees with respect to the second connecting member 42 in the second position. Taking a notebook computer as an example, the first connecting piece 41 is connected with the display part, the second connecting piece 42 is connected with the host part, the display part and the host part can rotate 360 degrees relatively, 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 at least 180 degrees relative to the second connecting piece 42 in the second posture, the base can be prevented from being beaten to the desktop, and one end, close to the display part, of the host part can be prevented from being pried (or supported). More preferably, the base may be slightly smaller than 180 degrees, for example 170 degrees, with respect to the second connecting member 42 in the second posture, so that the display portion (the first connecting member 41) of the notebook computer is ensured to be larger than 90 degrees with respect to the main unit portion (the second connecting member 42), and a gap is formed between the lower end of the display portion and the table top, and the gap provides a channel for air emitted from the heat dissipation air outlet (a side, close to the second rotating shaft, of the main unit portion) of the main unit portion, so that the amount of hot air flowing to the front surface of the display portion is reduced, and a certain protection effect is provided for the display screen.
The first control group is used for providing a first control point and a second control point, and the embodiment enables the first control group to comprise: the first assembly is provided with a first control point and is fixedly connected with the first rotating shaft and rotates along with the first rotating shaft; the second component with a second control point is fixedly connected with the second rotating shaft and rotates along with the second rotating shaft. And when the first control point is opposite to the second control point in the rotating process provided by the rotating shaft device, the second control piece group controls the first control point to be switched with the second control point. That is, the first control point is disposed on the first component rotating along with the first rotating shaft, and the second control point is disposed on the second component rotating along with the second rotating shaft, so that the overall structure of the first control member group is compact. Specifically, in this embodiment, the first assembly includes a first cam 21 coaxially disposed with the first rotating shaft, the first control point is a cambered surface recess (i.e. a first clamping groove 211) on the circumferential surface of the first cam 21, and the second assembly includes a second cam 22 coaxially disposed with the second rotating shaft, and the second control point is a cambered surface recess (i.e. a second clamping groove 221) on the circumferential surface of the second cam 22. As shown in fig. 14 to 18, 0 degrees, 120 degrees, 280 degrees, and 360 degrees in fig. 18 refer to angles of the first link 41 with respect to the second link 42, and correspond to a first posture shown in fig. 14, a second posture shown in fig. 15, a third posture shown in fig. 16, and a fourth posture shown in fig. 14, respectively, and at 120 degrees and 280 degrees, the arc surface depression of the first cam 21 is opposite to the arc surface depression of the second cam 22, so that the switching is completed once at 120 degrees and 280 degrees, that is, the switching from the first control point to the second control point is completed at 120 degrees, and the 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 that performs the control function during the rotation of 0 to 120 degrees and the first control point that performs the control function during the rotation of 280 to 360 degrees are two cambered surface recesses on the first cam 21, as shown in fig. 5, the first cam 21 has two first clamping grooves 211, and the angle between the two first clamping grooves 211 is equal to the aforementioned second angle, which is 160 ° in the present embodiment.
The present embodiment provides for the first control group to include: the third component is positioned between the first component and the second component 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, i.e., the first control point and the second control point multiplex the same component to exert the control function, which is advantageous in 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 cambered surface protrusions, which are respectively adapted to the first clamping groove 211 and the second clamping groove 221. As shown in fig. 18, the slider 8 is slidably disposed on the first base 11, the slider 8 slides upward to make the cambered surface protrusion at the upper end of the slider block into the cambered surface recess of the first cam 21 to lock, and the slider 8 slides downward to make the cambered surface protrusion at the lower end of the slider block into the cambered surface recess of the second cam 22 to lock. When the first control point and the second control point are not opposed, that is, when the first control point and the second control point are not rotated to the switchable posture, the arc surface protrusion of the slider 8 abuts against the circumferential surface of the first cam 21 or the second cam 22 to keep the current lock, for example, from 0 degrees to 120 degrees, and the arc surface protrusion of the lower end of the slider 8 abuts against the circumferential surface of the second cam 22 to keep the slider 8 locked with the first cam 21.
Further, the present embodiment makes the second control group include: the unlocking piece is used for driving the third component to unlock with the first control point in the process of locking the third component and rotating around the second rotating shaft together with the first control point and/or driving the third component to unlock with the second control point in the process of locking the third component and rotating around the first rotating shaft together with the second control point. That is, the unlocking of the third component and the first control point and/or the second control point can be achieved by the unlocking member through the rotation process, so that the user can unlock the sliding block 8 and the first cam 21 and/or the second cam 22 in the process of opening or closing the rotating shaft device, and the electronic equipment such as a notebook computer and the like using the rotating shaft device is more convenient to use. Preferably, the unlocking member includes a first stopper 6 and a second stopper 7, and the third component is locked with the first control point and rotates around the second rotation axis together to drive the first rotation axis 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 rotation axis together to unlock the third component from the second control point by the first stopper 6 and the second stopper 7 being engaged. The cooperation of the first stopper 6 and the second stopper 7 can provide an accurate physical stop point, that is, when the first stopper 6 abuts against the second stopper 7, the relative positional relationship of the first stopper 6 and the second stopper 7 is determined, so that the posture of the rotating shaft device can be accurately reproduced, thereby ensuring that the rotating shaft device is unlocked at a preset posture position. Specifically, in this embodiment, the second control member set includes a first gear 3 coaxially disposed with the first rotation shaft and fixed relative to the first cam 21, the first stop member 6 is a sector gear in driving connection with the first gear 3 via the idle gear 5, and the second stop member 7 is fixedly disposed 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 together with the first rotation shaft, the second stopper 7 and the second cam 22 both rotate together 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 idler gear 5.
As shown in fig. 18, the second stopper 7 has a non-circular hole connected to the second rotation shaft to enable the second stopper 7 to rotate together with the second rotation shaft after being mounted to the second rotation shaft, the second stopper 7 has a protruding stopper on its circumferential surface, and the slider 8 is locked with the first cam 21 during 0 degrees to 120 degrees so that the first rotation 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 integrally rotate about the second rotation shaft, i.e., the second rotation shaft provides rotation relative to the second stopper 7. At 120 degrees, the sector gear hits the protruding stop of the second stop 7, the moment that this protruding stop abuts against the sector gear prevents the base from continuing to rotate around the second rotation axis relative to the second stop 7, and just at this time, the cambered surface recess of the first cam 21 and the cambered surface recess of the second cam 22 are opposite, providing space for the sliding of the slider 8, so as the first connecting piece 41 continues to spread out relative to the second connecting piece 42, the first rotation axis is driven to rotate so as to drive the first cam 21 and the first gear 3 to rotate simultaneously relative to the base, 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 locks 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 rotation axis 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 3 simultaneously rotate relative to the base, i.e. the first rotation axis provides rotation. In this process, the sector gear rotates relative to the base and hits the protruding stop of the second stop 7 again at 280 degrees, the moment that the protruding stop abuts against the sector gear prevents the sector gear from continuing to rotate relative to the base, the sector gear is meshed with the idler gear 5, the idler gear 5 is meshed with the first gear 3, the protruding stop prevents the first gear 3 from continuing to rotate relative to the base, the first cam 21 does not continue to rotate relative to the base again because the first cam 21 and the first gear 3 are both arranged along with the first rotating shaft, namely, the first cam 21 and the first gear 3 are fixedly arranged relative to each other, and the cambered surface concave of the first cam 21 is opposite to the cambered surface concave of the second cam 22 at the moment, so that space is provided for sliding of the sliding block 8, and as the first connecting piece 41 continues to be unfolded relative to the second connecting piece 42, the first gears 3 and 5, the whole of the sector gear and the base are driven to rotate relative to the second stop 7 around the second rotating shaft, namely, the first gear 3, the idler gear 5, the whole of the sector gear and the base rotate relative to the second cam 22 around the second rotating shaft, the second cam 22 are forced to rotate relative to the sliding block 8 around the second cam 22. During the subsequent 280 to 360 degrees, the slide 8 is locked with the first cam 21, so that the first rotation axis 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 as a whole rotate about the second rotation axis relative to the second stop 7, i.e. the second rotation axis. When the motion is from 360 degrees to 0 degrees, the motion principle is the same as that of the process and only the motion direction is opposite, and the description is omitted here.
The application also provides a rotation method, which comprises the following steps:
the first body and the shell of the rotating shaft device form a first lock through a first control point of a first control piece group of the rotating shaft device and rotate around a second rotating shaft together by a first angle;
the first body rotates around the first rotating shaft to release the first locking through a second control piece group of the rotating shaft device;
the second body and the shell of the rotating shaft device form a second lock through a second control point of the first control piece group to rotate around the first rotating shaft for a second angle;
the second body rotates around the second rotating shaft through the second control piece group to release the second locking;
the first body and the shell of the rotating shaft device form a first lock together through a first control point of the first control piece group to rotate around the second rotating shaft for a third angle.
The application provides a rotation method, which is characterized in that the first body and the second body are two objects with relative rotation requirements, such as a display part and a host part of a notebook computer, and the relative rotation of the first body and the second body is realized through a rotating shaft device. The rotation method provided by the application has the advantages that the rotation angle borne by the second rotation shaft is divided into two sections (namely the first angle and the third angle) at intervals, so that when the relative rotation angle of the first body and the second body is required to be more than 180 degrees, the rotation angle borne by the first rotation shaft and the second rotation shaft can be conveniently and 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 one turn with respect to the second body.
