Detailed Implementation

[0055] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details a rotating mechanism and electronic device according to this utility model, including its specific implementation, structure, features, and effects. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0057] Currently, some electronic devices such as laptops on the market use a dual-switching hinge structure to connect the display and system ends, allowing the display and system ends to rotate independently. The dual-switching hinge innovatively solves the functional requirement of dual switching, while also featuring a high-precision switching angle design and stable production output. However, the current dual-switching hinge structure has many components, requiring high installation precision for each component.

[0058] like Figures 1 to 4 As shown, this utility model embodiment provides a rotating mechanism, which mainly includes a rotating shaft assembly and a switching assembly.

[0059] The rotating shaft assembly mainly includes a first rotating shaft 1 and a second rotating shaft 2. The first rotating shaft 1 can connect to the first body to be rotated, and the second rotating shaft can connect to the second body to be rotated. The switching assembly mainly includes a first rotating wheel 3, a second rotating wheel 4, a slider 6, and a switching block 7. The first rotating wheel 3 is fixed on the first rotating shaft 1 and can rotate synchronously with the first rotating shaft 1, and the second rotating wheel 4 is fixed on the second rotating shaft 2 and can rotate synchronously with the second rotating shaft 2.

[0060] The first rotating wheel 3 is provided with an adjacent and fixedly connected first guide part 31 and first locking part 32 along its axial direction, and the second rotating wheel 4 is provided with an adjacent and fixedly connected second guide part 41 and second locking part 42 along its axial direction.

[0061] In this embodiment, the guide portion and the locking portion on the two rotating wheels are adjacent and fixedly connected. It can be understood that the guide portion and the locking portion are two independent parts on the first rotating wheel. These two independent parts are relatively stationary and close to each other. It can also be understood that the guide portion and the locking portion can be machined separately on the same rotating wheel.

[0062] like Figure 2 and Figure 3 As shown, the switching block 7 is located between the first locking part 32 and the second locking part 42, and the slider 6 is located between the first guide part 31 and the second guide part 41.

[0063] The switching block 7 can move relative to the rotating shaft assembly and cooperate with either the first locking part 32 or the second locking part 42 to lock the corresponding rotating shaft so that the locked rotating shaft cannot rotate, and to release the other rotating shaft so that the released rotating shaft can rotate. The slider 6 can cooperate with the first guide part 31 and the second guide part 41 respectively, so that the released first rotating shaft 1 or second rotating shaft 2 can rotate by a preset angle. Locking the rotating shaft can be understood as restricting its rotation, while releasing the rotating shaft can be understood as allowing it to rotate.

[0064] For example, when the switching block 7 is engaged with the first locking part 32, the first rotating shaft 1 is locked so that it cannot rotate, while the second rotating shaft 2 is released so that it can rotate; when the switching block 7 is engaged with the second locking part 42, the second rotating shaft 2 is locked so that it cannot rotate, while the first rotating shaft 1 is released so that it can rotate.

[0065] The switching block 7 cooperates with either the first locking part 32 or the second locking part 42 to lock the corresponding rotating shaft so that the locked rotating shaft cannot rotate, and releases the other rotating shaft so that the released rotating shaft can rotate. The situations include at least the following:

[0066] When the switching block 7 engages with the first locking part 32 to lock the first rotating shaft 1, the second rotating shaft 2 can rotate a certain angle. Then, when the switching block 7 is moved to engage with the second locking part 42 to lock the second rotating shaft, the first rotating shaft 1 rotates another certain angle. The sum of the rotation angles of the second rotating shaft 2 and the first rotating shaft 1 can be 360 ​​degrees.

[0067] Alternatively, when the switching block 7 engages with the first locking part 32 to lock the first rotating shaft 1, the second rotating shaft 2 can rotate a certain angle. Then, when the switching block 7 is moved to engage with the second locking part 42 to lock the second rotating shaft, the first rotating shaft 1 rotates another certain angle. Finally, the switching block 7 is moved again to engage with the first locking part 32 to lock the first rotating shaft 1, and the second rotating shaft 2 rotates another certain angle. The sum of the rotation angles of the second rotating shaft 2 and the first rotating shaft 1 can be 360 ​​degrees.

[0068] And / or, the switching block 7 can move relative to the rotating shaft assembly and separate from the first locking part 32 and the second locking part 42 respectively, so as to release the first rotating shaft 1 and the second rotating shaft 2 respectively, so that the first rotating shaft 1 and the second rotating shaft 2 rotate synchronously, and the slider 6 can cooperate with the first guide part 31 and the second guide part 41 respectively, so that the first rotating shaft 1 and the second rotating shaft 2 rotate synchronously by a preset angle. Here, separation can be understood as the switching block 7 having no cooperation with the first locking part 32 and the second locking part 42, and the two rotating shafts are not locked but released simultaneously, thereby realizing the synchronous rotation of the two rotating shafts.

[0069] Among them, the situations in which the switching block 7 separates from the first locking part 32 and the second locking part 42 respectively, so as to release the first rotating shaft 1 and the second rotating shaft 2 respectively, and make the first rotating shaft 1 and the second rotating shaft 2 rotate synchronously include at least the following situations:

[0070] After the switching block engages with the two locking parts in sequence, it then disengages from the two locking parts respectively. That is, after the first rotating shaft 1 and the second rotating shaft 2 rotate independently by a certain angle, the first rotating shaft 1 and the second rotating shaft 2 can rotate synchronously by a certain angle.

[0071] Alternatively, after the switching block 7 engages with the first locking part 32, it can be separated from both the first locking part 32 and the second locking part 42, and then engage with the second locking part 42 again. That is, after the second rotating shaft 2 rotates independently by a certain angle, the first rotating shaft 1 and the second rotating shaft 2 rotate synchronously by a certain angle, and finally the first rotating shaft 1 rotates independently by a certain angle.

[0072] Alternatively, after the switching block 7 engages with the second locking part 32, it can be separated from the first locking part 32 and the second locking part 42 respectively, and then engage with the first locking part 42 again. That is, after the first rotating shaft 2 rotates independently by a certain angle, the first rotating shaft 1 and the second rotating shaft 2 rotate synchronously by a certain angle, and finally the second rotating shaft 2 rotates independently by a certain angle.

[0073] In this embodiment, the preset angle range of rotation of the first rotating shaft 1 and / or the second rotating shaft 2 is not specifically limited, and can be determined according to the structure of the slider 6, the first guide part 31 and the second guide part 41.

[0074] In this embodiment, the rotating mechanism has a first guide portion 31 and a first locking portion 32 that are adjacent to and fixedly connected on the first rotating wheel 3, and a second guide portion 41 and a second locking portion 42 that are adjacent to and fixedly connected on the second rotating wheel 4. Compared to the traditional method where the guide portion and locking portion are separate, this invention integrates the first guide portion 31 and the first locking portion 32, as well as the second guide portion 41 and the second locking portion 42, onto a single rotating wheel. This reduces the number of components in the rotating mechanism, improves the installation accuracy, and lowers costs. Furthermore, compared to the traditional method of assembling the guide portion before the locking portion, or vice versa, this application integrates the guide portion and the locking portion onto a single rotating wheel, simplifying the assembly process and improving the assembly efficiency of the rotating mechanism.

[0075] It should be noted that the rotating mechanism of this embodiment is applicable to electronic devices such as laptops that include a display and a system. This embodiment only uses a laptop as an example for illustration. The system in the laptop is fixedly connected to the first rotating shaft 1 of the rotating mechanism, and the display in the laptop is fixedly connected to the second rotating shaft 2 of the rotating mechanism. This rotating mechanism allows the display to rotate relative to the system.

[0076] like Figure 5 and Figure 6 As shown, in some embodiments, the first guide portion 31 and the first locking portion 32 can be integrally formed to form the first rotating wheel 3. And / or, the second guide portion 41 and the second locking portion 42 can be integrally formed to form the second rotating wheel 4.

[0077] The integral molding can be understood as the first guide part 31 and the first locking part 32 being directly machined on the first rotating wheel 3, and the second guide part 41 and the second locking part 42 being machined on the second rotating wheel 4.

[0078] Machining guide parts and locking parts separately on the rotating wheel not only facilitates machining but also reduces positioning errors between the two, thereby reducing the overall installation error of the rotating shaft structure.

[0079] In some embodiments, the switching block 7 is movable relative to the rotating shaft assembly and has at least a first position, a second position, and a third position in the direction of movement. For example... Figure 2 As shown, when the switching block 7 is moved to the first position, the switching block 7 engages with the first locking part 32.

[0080] like Figure 4 As shown, when the switching block 7 moves to the second position, the switching block 7 engages with the second locking part 42.

[0081] In some embodiments, when the switching block 7 moves from the first position or the second position to the third position, the switching block 7 separates from the first locking part 32 and the second locking part 42, respectively.

[0082] Therefore, in the rotating mechanism of this application, when the switching block 7 is in the first or second position, one of the two rotating shafts can rotate; when it is in the third position, both rotating shafts can rotate synchronously. That is, the rotating mechanism of this application can achieve both asynchronous and synchronous rotation.

[0083] The structure of the guide portion and the locking portion on the two rotating wheels of the rotating mechanism in this application is different when the two shafts rotate synchronously, compared with the structure of the guide portion and the locking portion on the two rotating wheels when the two shafts rotate asynchronously. This embodiment will only be described using the case of the rotating mechanism rotating synchronously on two shafts as an example.

[0084] Furthermore, in this embodiment, the first position and the second position can be any two intervals between the cutting block 2 in its direction of movement, or two extreme positions. For example, when the switching block 2 moves in the vertical direction, the first position can be the bottommost position in the vertical direction, and the second position can be the topmost position in the vertical direction. The third position can be any position between the first position and the second position.

[0085] The switching block 7 can move relative to the rotating shaft assembly. It can move along the axis perpendicular to the rotating shaft assembly or in other directions. In this embodiment, we will only use the example of the switching block 7 moving along the axis perpendicular to the rotating shaft assembly as an example.

[0086] like Figures 1 to 4 As shown, in some embodiments, the rotating mechanism includes a connecting component 5, which is rotatably connected to the first rotating shaft 1 and the second rotating shaft 2, respectively. The connecting component 5 is mainly used to enable the two rotating shafts to be arranged side by side, and the two rotating shafts can rotate relative to the connecting component 5 respectively.

[0087] The connecting assembly 5 includes at least a first connecting piece 51 and a second connecting piece 52. The first connecting piece 51 is opposite to the first end of the first rotating wheel 3 and the first end of the second rotating wheel 4, respectively, and the second connecting piece 52 is opposite to the second end of the second rotating wheel 4. That is, the first rotating wheel 3 and the second rotating wheel 4 are respectively located between the two connecting pieces.

[0088] The slider 6 is slidably connected to the first connecting piece 51 to guide its movement. Specifically, the slider 6 moves relative to the rotating shaft assembly under the constraint of the first connecting piece 51. The switching block 7 is slidably connected to the second connecting piece 52 to guide its movement. Specifically, the switching block 7 moves relative to the rotating shaft assembly under the constraint of the second connecting piece 52.

[0089] Connecting the two rotating shafts with two connecting pieces not only maintains the rigidity and stability of the rotating structure, but also guides the movement of the slider 6 and the switching block 7, reducing the need for additional components.

[0090] Meanwhile, the first connecting piece 51 contacts the end face of the first end of the first rotating wheel 3, and the second connecting piece 52 contacts the end face of the second end of the second rotating wheel 4. The two connecting pieces can provide friction surfaces, thereby stabilizing and improving the torque of the rotating structure.

[0091] The structure of the two connecting pieces in this embodiment is not specifically limited. Each of the two connecting pieces is provided with two opposite pivot holes. The first pivot 1 and the second pivot 2 pass through the pivot holes of the corresponding two connecting pieces.

[0092] The two connecting pieces are preferably made of abrasion-resistant materials, such as common stainless steel and special alloy steel, or polymer materials such as polyimide, polycarbonate and nylon.

[0093] like Figure 7 As shown, in some embodiments, the first connecting piece 51 has a first guide plate 511 and a second guide plate 512. The first guide plate 511 and the second guide plate 512 can be located on opposite sides of the slider 6, and the slider 6 is slidably connected to the first guide plate 511 and the second guide plate 512 respectively. When the first rotating shaft 1 or the second rotating shaft 2 is rotated, the first guide plate 511 and the second guide plate 512 cooperate with each other to make the slider 6 move along the axial direction of the two rotating shafts, thereby preventing the slider 6 from rotating.

[0094] There are several ways in which the slider 6 can be slidably connected to the first guide plate 511 and the second guide plate 512. For example, the distance between the first guide plate 511 and the second guide plate 512 is approximately the same as the thickness of the slider 6. The slider 6 is placed between the two guide plates, and the outer circumferential surface of the slider 6 abuts against the two guide plates respectively. The two guide plates extend along the axial direction of the rotating shaft respectively, and the slider 6 moves along the axial direction of the rotating shaft within the space defined by the two guide plates.

[0095] For example, such as Figure 7 and Figure 8 As shown, in some other embodiments, the first guide plate 511 and the second guide plate 512 are respectively provided with transverse grooves 513 extending along the axial direction of the rotating shaft assembly on their opposite sides. The slider 6 is provided with a transverse slider 63 embedded in the transverse groove 513. The transverse groove 513 and the transverse slider 63 cooperate with each other to ensure that the slider 6 moves along the axial direction of the rotating shaft assembly.

[0096] like Figure 9 As shown, in some embodiments, the second connecting piece 52 has a third guide plate 521 and a fourth guide plate 522. The third guide plate 521 and the fourth guide plate 522 are located on opposite sides of the switching block 7. The switching block 7 is slidably connected to the third guide plate 521 and the fourth guide plate 522 respectively, and the third guide plate 521 and the fourth guide plate 522 cooperate with each other to make the switching block 7 move in the radial direction of the two rotating axes, thereby preventing the switching block 7 from rotating.

[0097] The cooperation method between the switching block 7 and the third guide plate 521 and the fourth guide plate 522 can be the same as the cooperation method between the slider 6 and the first guide plate 511 and the second guide plate 512.

[0098] like Figure 9 and Figure 10As shown, in some implementations, the third guide plate 521 and the fourth guide plate 522 are respectively provided with vertical sliders 523, and the switching block 7 is provided with a vertical groove 70. The vertical sliders 523 of the two guide plates are respectively embedded in the vertical groove 70. With the cooperation of the vertical sliders 523 and the vertical groove 70, the switching block 7 moves in the radial direction of the rotating shaft assembly.

[0099] like Figure 1 As shown, in some embodiments, the first guide plate 511 and the second guide plate 512 on the first connecting piece 51 extend toward the second connecting piece 52, and the third guide plate 521 and the fourth guide plate 522 on the second connecting piece 52 extend toward the first connecting piece 51. This structural arrangement can make the rotating mechanism structure more compact.

[0100] like Figure 1 As shown, in some embodiments, the rotating mechanism further includes a first friction plate 8, which is rotatably connected to the first rotating shaft 1 and the second rotating shaft 2 respectively. The first friction plate 8 is located on the side of the first connecting plate 51 opposite to the second connecting plate 52. A second friction plate 9 is provided between the first friction plate 8 and the first connecting plate 51. The second friction plate 9 contacts the first friction plate 8 and the first connecting plate 51 respectively, that is, one side of the second friction plate 9 contacts the first connecting plate 51, and the other side of the second friction plate 9 contacts the second connecting plate 52, thereby further improving the friction of the torque of the two rotating shafts.

[0101] The structure of the first friction plate 8 and the second friction plate 9 is not specifically limited. The first friction plate 8 can be connected to the first rotating shaft 1 and the second rotating shaft 2 at the same time. The second friction plate 9 can be divided into two pieces, that is, the first rotating shaft 1 and the second rotating shaft 2 are each equipped with a second friction plate 9.

[0102] like Figure 1 As shown, in some embodiments, the first rotating shaft 1 is provided with a first connecting part 10 for connecting the system end, and the second rotating shaft 2 is provided with a second connecting part 20 for connecting the display end. The first connecting part 10 and the second connecting part 20 are respectively located on the side of the first friction plate 8 away from the second friction plate 9 on the corresponding rotating shaft and are in contact with the first friction plate 8, so that both sides of the first friction plate 8 provide friction force.

[0103] In some embodiments, the first guide portion 31 on the first rotating wheel 3 is located on the side of the first locking portion 32 facing the first connecting portion, and the second guide portion 41 on the second rotating wheel 4 is located on the side of the second locking portion 42 facing the second connecting portion.

[0104] In some embodiments, as Figure 5 and Figure 6As shown, the first locking part 32 on the first rotating wheel 3 includes a first groove 320 provided on the outer peripheral wall of the rotating wheel and a first annular part 321 located in the same circumferential direction as the first groove 320. The second locking part 42 on the second rotating wheel 4 includes a second groove 420 provided on the outer peripheral wall of the rotating wheel and a second annular part 421 located in the same circumferential direction as the second groove 420.

[0105] The first end of the switching block 7 has a first protrusion 71 that can be inserted into the first groove 320, and the second end has a second protrusion 72 that can be inserted into the second groove 420.

[0106] It should be noted that when the switching block 7 moves radially along the shaft assembly so that its first protrusion 71 is inserted into the first groove 320 on the first rotating wheel 3, and the second protrusion 72 abuts against the second annular surface 421 on the second rotating wheel 4, the first rotating shaft 1 is locked and cannot rotate. At this time, the position of the switching block 7 is the first position. When the switching block 7 moves radially along the shaft assembly so that its second protrusion 72 is inserted into the second groove 420 on the second rotating wheel 4, and the first protrusion 71 abuts against the first annular surface 321 on the first rotating wheel 3, the second rotating shaft 2 is locked and cannot rotate. At this time, the position of the switching block 7 is the second position.

[0107] like Figure 5 As shown, the first guide portion 31 is a first guide groove provided on the outer peripheral wall of the first rotating wheel 3. The first guide groove is a spiral groove. Figure 6 As shown, the second guide part 41 is a second guide groove provided on the outer peripheral wall of the second rotating wheel 4. The second guide groove includes a first annular groove 410, a first straight groove 411 and a second annular groove 412 connected sequentially along the axial direction of the second rotating wheel 4. That is, the end of the first annular groove 410 is connected to the beginning of the first straight groove 411, and the end of the first straight groove 411 is connected to the beginning of the second annular groove 412.

[0108] The axes of the first annular groove 410 and the second annular groove 412 are coaxial with the axis of the second rotating wheel 4. For example... Figure 8 As shown, the slider 6 has a first guide block 61 at its first end along the axial direction perpendicular to the rotating shaft assembly, and the first guide block 61 is inserted into the first guide groove. The slider 6 has a second guide block 62 at its second end along the axial direction perpendicular to the rotating shaft assembly, and the second guide block 62 is inserted into the second guide groove.

[0109] It should be noted that the direction of rotation of the first guide groove and the relative position of the first annular groove 410 and the second annular groove 412 in this embodiment determine whether the released first rotating shaft 1 and the second rotating shaft 2 rotate in a counterclockwise direction or in a counterclockwise direction.

[0110] by Figures 2 to 4 The rotating structure shown is used as an example for explanation, wherein the rotation direction of the first guide groove on the first rotating wheel 3 is counterclockwise. For example... Figure 2 As shown, when the angle between the system end and the display end is the first angle, for example, 0 degrees, the first protrusion 71 of the first end of the switching block 7 is inserted into the first groove 320 on the first rotating wheel 3, and the second protrusion 72 of the second end abuts against the second annular surface 421 on the second rotating wheel 4. At this time, the degree of freedom of the switching block 7 in the direction perpendicular to the rotating axis is restricted, thereby locking the first rotating shaft 1 and preventing it from rotating. The first guide block 61 of the first end of the slider 6 is located at the left end of the first guide groove, and the second guide block 62 of the second end is located at the free end of the first annular groove 410. At this time, the second rotating shaft 2 can be rotated counterclockwise, and the second guide block 62 moves along the first annular groove 410. When it moves to the connection between the first annular groove 410 and the first straight groove 411, since the angle between the first straight groove 411 and the first annular groove 410 is 90 degrees, the second rotating shaft 2 cannot continue to rotate. When the angle between the system end and the display end is the second angle, see Figure 3 As shown, at this time, the second groove 420 on the second rotating wheel 4 is opposite to the second protrusion 72 of the slider 6, and the freedom restriction of the switching block 7 in the direction perpendicular to the rotating shaft assembly is removed. Therefore, the first rotating shaft 1 is unlocked and the first rotating shaft 1 can rotate.

[0111] like Figure 3 As shown, when the angle between the system end and the display end is the second angle, for example, 90 degrees, since the first rotating shaft 1 is unlocked and the rotation direction of the first guide groove is counterclockwise, the first rotating shaft 1 can be rotated clockwise. This simultaneously moves the second guide block 62 on the slider 6 along the first straight groove 411, and the first guide block 61 on the slider 6 along the first guide groove. The first rotating shaft 1 also pushes the switching block 7 upwards, causing the second protrusion 72 of the slider 6 to insert into the second groove 420 on the second rotating wheel 4, thereby locking the second rotating shaft 2 so that it cannot rotate. Figure 4 As shown, when the second guide block 62 moves to the connection between the first straight groove 411 and the second annular groove 412, the first guide block 61 at the first end of the slider 6 also moves to the right end of the first guide groove. At this time, the first rotating shaft 1 cannot continue to rotate, and the angle between the system end and the display end is the third angle, for example, the third angle is 270 degrees.

[0112] Therefore, the rotating mechanism in this embodiment realizes asynchronous rotation of two rotating shafts, that is, only one rotating shaft can rotate within a certain time period.
