Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electronic devices, and particularly to a rotating shaft device and an electronic device. Background Art

[0002] At present, the heat dissipation capacity of laptop computers is weak, so that the heat generated during the operation of laptop computers cannot be dissipated in time, which will lead to too high a temperature of laptop computers, thus resulting in a decline in the performance of laptop computers and further failing to meet the usage requirements of users. Therefore, how to improve the heat dissipation capacity of laptop computers has become an urgent problem to be solved. Summary of the Invention

[0003] The embodiments of the present application provide a rotating shaft device and an electronic device, which can improve the heat dissipation capacity of the electronic device.

[0004] In a first aspect of the present application, a rotating shaft device is provided, including a first rotating shaft, a second rotating shaft, and a link mechanism. The link mechanism includes a first rod, a second rod, and a third rod. The first end of the first rod is movably connected to the first end of the second rod, the second end of the first rod is movably connected to the first end of the third rod, the third end of the first rod is used for fixedly connecting with a foot pad, and the second end of the second rod is connected to the second rotating shaft. The first rotating shaft is in transmission connection with the second rotating shaft. The first rotating shaft is used for receiving a driving force. During the rotation of the first rotating shaft, the second rotating shaft is used for driving the foot pad to perform a linear motion through the link mechanism under the drive of the first rotating shaft.

[0005] Since the first rod is fixedly connected to the foot pad, the first rod and the foot pad move linearly synchronously during the process that the second rotating shaft drives the foot pad to perform a linear motion through the link mechanism. When the rotating shaft device is applied to an electronic device, after the first rotating shaft receives the driving force, the first rotating shaft drives the second rotating shaft to rotate. While the second rotating shaft rotates, it drives the second rod to rotate. While the second rod rotates, it drives the first rod to perform a linear motion. While the first rod performs a linear motion, the third rod rotates. Since the second rod and the third rod are respectively connected to both ends of the first rod, the structure of the link mechanism is similar to that of a four-bar linkage, so that the reliability and stability of the linear motion of the first rod can be improved, and further the smoothness and stability of the linear motion of the foot pad can be improved.

[0006] In addition, since the foot pad is fixedly connected to the first rod, the first rod can drive the foot pad to move linearly while moving linearly, so that the length of the foot pad extending out of the electronic device can become longer, and thus the space between the electronic device and the tabletop supporting the electronic device is increased, so as to increase the heat dissipation capacity of the electronic device. At the same time, since the foot pad is an existing part in the electronic device, improving the heat dissipation capacity of the electronic device by adjusting the length of the foot pad extending out of the electronic device will not damage the appearance of the electronic device. In addition, the rotating shaft device will not limit the thickness of the electronic device and can reduce the thickness of the electronic device to meet the design requirements of thin and light.

[0007] In a possible implementation manner, the link mechanism further includes at least one fourth rod, and at least one fourth rod is arranged on at least one of the opposite sides of the first rod. Opposite ends of each fourth rod are respectively rotatably connected to the second rod and the third rod.

[0008] When a fourth rod is arranged on one of the opposite sides of the first rod, the first rod, the second rod, the third rod and the fourth rod can form a stable parallelogram structure, which can further improve the smoothness and stability when the first rod moves. Or, when fourth rods are respectively arranged on the opposite sides of the first rod, the second rod, the third rod and the two fourth rods can form a stable parallelogram structure, which can also further improve the smoothness and stability when the first rod moves.

[0009] In addition, by connecting the second rod and the third rod through the fourth rod, the second rod can drive the third rod to rotate through the fourth rod, so that the third rod can also drive the first rod to move linearly, and further the overall force on the first rod can be made uniform to make the movement of the first rod smoother and more stable.

[0010] In a possible implementation manner, one of the first rod and the second rod is provided with a first strip-shaped hole, and a part of the other is movably arranged inside the first strip-shaped hole.

[0011] The rotating shaft device provided by the embodiment of the present application can drive the first rod to move linearly while the second rod rotates by providing a first strip-shaped hole on the first rod or the second rod.

[0012] In a possible implementation manner, the first rod is provided with a first strip-shaped hole, and the second rod includes a first branch at least partially arranged inside the first strip-shaped hole. With such a setting, on the premise of realizing that the second rod drives the first rod to move linearly, the structures of the first rod and the second rod can be simplified.

[0013] In a possible implementation manner, one of the first rod and the third rod is provided with a second strip-shaped hole, and a part of the other is movably arranged inside the second strip-shaped hole.

[0014] The shaft device provided by the embodiment of the present application can avoid the interference of the third rod on the linear motion of the first rod by providing a second strip-shaped hole on the first rod or the third rod. In addition, when the third rod is connected to the second rod through the fourth rod, the third rod can also drive the first rod to perform a linear motion through the second strip-shaped hole, so as to improve the smoothness and reliability of the motion of the first rod.

[0015] In a possible implementation manner, the first rod is provided with a second strip-shaped hole, and the third rod includes a second branch portion at least partially disposed in the second strip-shaped hole. Such a setting can simplify the structures of the first rod and the third rod on the basis of realizing the linear motion of the first rod. In addition, when the second rod is connected to the third rod, the connection difficulty between the second rod and the third rod can be reduced.

[0016] In a possible implementation manner, the shaft device further includes a support member, and the support member includes a guiding portion connected to the first rod, and the guiding portion is used to make the first rod perform a linear motion.

[0017] During the process of the second rod driving the first rod to move, through the guiding of the first rod by the guiding portion, the first rod can perform a linear motion.

[0018] In a possible implementation manner, one of the guiding portion and the first rod includes a guiding hole, and the other includes a protruding portion at least partially disposed in the guiding hole.

[0019] During the process of the second rod driving the first rod to move, the protruding portion is in sliding fit with the inner wall of the guiding hole, so that the inner wall of the guiding hole can guide the protruding portion to perform a linear motion, and further the guiding portion can guide the first rod to perform a linear motion.

[0020] In a possible implementation manner, the guiding portion is provided with a plurality of guiding holes, and the first rod includes a plurality of protruding portions, and each protruding portion corresponds to a guiding hole.

[0021] The shaft device provided by the embodiment of the present application guides the first rod to perform a linear motion by matching a plurality of guiding holes with a plurality of protruding portions, which can improve the accuracy of the first rod performing a linear motion.

[0022] In a possible implementation manner, the number of the guiding portions is two, and the first rod is disposed between the two guiding portions.

[0023] The shaft device provided by the embodiment of the present application guides the first rod to perform a linear motion through two guiding portions, which can not only further improve the guiding effect of guiding the first rod, but also avoid the first rod moving in a direction perpendicular to the arrangement direction of the two guiding portions, and can improve the reliability of the motion of the first rod.

[0024] In a possible implementation, the guiding portion is disposed between the second rod member and the third rod member. The space between the second rod member and the third rod member can be utilized to arrange the guiding portion, which can improve the integration degree of the rotating shaft device and is beneficial to the miniaturization of the rotating shaft device.

[0025] In a possible implementation, the supporting member is further provided with an avoidance notch for avoiding the first rotating shaft, the second rotating shaft, the first rod member, and the second rod member.

[0026] The rotating shaft device provided by the embodiment of the present application can avoid the first rotating shaft, the second rotating shaft, the first rod member, and the second rod member through the avoidance notch, which can prevent the supporting member from interfering with the movement of the first rotating shaft, the second rotating shaft, the first rod member, and the second rod member, thereby improving the integration degree of the rotating shaft device and further being beneficial to the miniaturization of the rotating shaft device.

[0027] In a possible implementation, the supporting member is further provided with at least one of a first groove, a second groove, a third groove, and a fourth groove. The first groove is used for avoiding the first rod member, the second groove is used for avoiding the second rod member, the third groove is used for avoiding the third rod member, and the fourth groove is used for avoiding the fourth rod member.

[0028] The rotating shaft device provided by the embodiment of the present application is provided with at least one of a first groove, a second groove, a third groove, and a fourth groove on the supporting member, so that the supporting member can avoid the first rod member, the second rod member, the third rod member, and the fourth rod member, thereby improving the integration degree of the rotating shaft device on the premise of satisfying the movement of the link mechanism and further being beneficial to the miniaturization of the rotating shaft device.

[0029] In a possible implementation, the supporting member further includes a first stop portion, and the first rotating shaft further includes a second stop portion. The first stop portion is used for abutting against the second stop portion to limit the rotation of the first rotating shaft.

[0030] The rotating shaft device provided by the embodiment of the present application can prevent the first rotating shaft from continuing to rotate by the abutment of the first stop portion and the second stop portion, thereby restricting the angular range of rotation of the first rotating shaft.

[0031] In a possible implementation, the first rotating shaft includes a first tooth portion, and the second rotating shaft includes a second tooth portion. During the meshing of the first tooth portion and the second tooth portion, the second rotating shaft drives the first rod member to perform a linear motion through the second rod member.

[0032] During the rotation of the first rotating shaft, the first rotating shaft can drive the second rotating shaft to rotate through the engagement of the first tooth part and the second tooth part, so as to transmit the driving force to the second rotating shaft, and the second rotating shaft drives the first rod to move linearly. In addition, the distance of the linear motion of the first rod can be controlled by controlling the engagement time of the first tooth part and the second tooth part, and the length of the foot pad extending out of the electronic device can be controlled. In addition, during the process when the first tooth part and the second tooth part are not engaged, the first rotating shaft will not drive the second rotating shaft to rotate while rotating, which can improve the application range of the first rotating shaft.

[0033] In a possible implementation manner, the first rotating shaft includes a first convex part, and the second rotating shaft includes a second convex part. Wherein, the first convex part is provided with a first notch, and during the process of the first rotating shaft driving the second rotating shaft to rotate, the first notch is used to avoid the second convex part, which can prevent the first convex part and the second convex part from interfering with each other, so as to avoid the first rotating shaft and the second rotating shaft from being unable to rotate, and further ensure that the first rotating shaft transmits the driving force to the second rotating shaft.

[0034] In a possible implementation manner, the first rotating shaft includes a first convex part, and the second rotating shaft includes a second convex part. Wherein, during the process when the first rotating shaft does not drive the second rotating shaft to rotate, the second notch is used to cooperate with the first convex part to prevent the second rotating shaft from rotating in the reverse direction relative to the first rotating shaft. By the cooperation of the first convex part and the second notch, the second rotating shaft does not rotate while the first rotating shaft rotates, so as to avoid the first rod from retracting due to the reverse rotation of the second rotating shaft, and further keep the length of the foot pad extending out of the electronic device unchanged.

[0035] In a possible implementation manner, the second convex part is further provided with a third notch, and during the rotation of the second rotating shaft, the third notch is used to avoid the first rod, which can ensure the normal operation of the second rotating shaft and the first rod. In addition, the distance between the second rotating shaft and the first rod can be reduced, so as to reduce the size of the rotating shaft device in the arrangement direction of the second rotating shaft and the first rod, which is beneficial to the miniaturization of the rotating shaft device.

[0036] In a possible implementation manner, the rotating shaft device further includes a foot pad, and the foot pad is fixedly connected to the third end of the first rod.

[0037] In the second aspect of the present application, an electronic device is provided, including a first part, a second part and a rotating shaft device according to any one of the first aspect, the first part is fixedly connected to the first rotating shaft of the rotating shaft device, and the second part is provided with an opening, wherein: the electronic device further includes a foot pad fixedly connected to the first rod of the rotating shaft device, and a part of the foot pad is arranged outside the second part through the opening. Or, a part of the foot pad of the rotating shaft device is arranged outside the second part through the opening.

[0038] When the electronic device is placed on a tabletop, the first part rotates relative to the second part, causing the angle between the first part and the second part to gradually increase, so as to unfold the electronic device. During the unfolding process, the first part drives the first rotating shaft to rotate, and the first rotating shaft can drive the foot pad to move linearly through a link mechanism and the second rotating shaft, so that the length of the foot pad extending out of the electronic device increases, thereby increasing the space between the electronic device and the tabletop, and further improving the heat dissipation capacity of the electronic device. In addition, the method of increasing the length of the foot pad extending out of the electronic device by using the rotating shaft device in the first aspect will not affect the appearance of the electronic device. In addition, the thickness of the electronic device can be reduced, which is beneficial to the thinning design.

[0039] In a possible implementation manner, the number of the rotating shaft devices is two, and the two rotating shaft devices are symmetrically arranged. Each first rod of the rotating shaft device is connected with a foot pad. BRIEF DESCRIPTION OF THE DRAWINGS

[0084] In the related art, the heat dissipation ability of a laptop is weak, so that the heat generated when the laptop is working cannot be dissipated in time, which will cause the temperature of the laptop to be too high, thus resulting in a decline in the performance of the laptop, and further unable to meet the usage requirements of users. Therefore, how to improve the heat dissipation ability of a laptop has become an urgent problem to be solved.

[0085] In view of this, the embodiments of the present application provide a rotating shaft device 500 and an electronic device 100. By receiving a driving force through the rotating shaft device 500 and driving the foot pad 400 to perform a linear motion, the length of the foot pad 400 extending out of the electronic device 100 can be increased, so that the space between the electronic device 100 and the tabletop supporting the electronic device 100 can be increased, and further the heat dissipation ability of the electronic device 100 can be improved. In addition, since the foot pad 400 is an existing part of the electronic device 100, the appearance of the electronic device 100 will not be damaged. In addition, the rotating shaft device 500 and the foot pad 400 can also be decoupled from the thickness of the electronic device 100, so that the thickness of the electronic device 100 can be reduced, and further a thinning design can be achieved.

[0086] The electronic device 100 in the embodiments of the present application may include, but is not limited to, a laptop, a keyboard device for detachably connecting to a tablet computer, etc. Among them, in the embodiments of the present application, a laptop is taken as an example of the above-mentioned electronic device 100 for illustration.

[0087] Figure 1 FIG. is a schematic structural diagram of an electronic device provided by an embodiment of the present application, Figure 2 is Figure 1 an exploded view of the electronic device in.

[0088] Referring to Figure 1 as shown, the electronic device 100 provided by the embodiments of the present application may include a first part 200, a second part 300, a foot pad 400, and a rotating shaft device 500. Among them, the first end of the rotating shaft device 500 is fixedly connected to the first part 200, and the second end of the rotating shaft device 500 is fixedly connected to the foot pad 400. The second part 300 is provided with an opening, and a part of the foot pad 400 is disposed outside the second part 300 through the opening. The foot pad 400 is used to abut against the tabletop to support the electronic device 100.

[0089] It should be noted that in addition to being juxtaposed with the rotating shaft device 500, the foot pad 400 can also be one of the components constituting the rotating shaft device 500. Therefore, in some embodiments, the electronic device 100 may also include a first part 200, a second part 300, and a rotating shaft device 500. The rotating shaft device 500 may include a foot pad 400 partially disposed outside the second part 300 through an opening.

[0090] See Figure 2 As shown, the number of the rotating shaft devices 500 can be two. The two rotating shaft devices 500 are symmetrically arranged, and each rotating shaft device 500 is connected with a foot pad 400, which can ensure the stability of the electronic device 100.

[0091] Since the electronic device 100 is a laptop computer, therefore, see Figure 2 As shown, the first part 200 may include a display screen 210 and a first housing 220, and the second part 300 may include a keyboard module 310 and a second housing 320. The keyboard module 310 may include a third housing and a keyboard. Among them, the first part 200 is rotatably connected to the second housing 320, so that the first part 200 is rotatably connected to the second part 300.

[0092] See the figure. The rotating shaft device 500 is disposed inside the second part 300. The first rotating shaft 10 of the rotating shaft device 500 is used for fixedly connecting with the first housing 220, and the bearing member 40 of the rotating shaft device 500 is used for fixedly connecting with the second housing 320. During the rotation of the first part 200 relative to the second part 300, the first housing 220 drives the foot pad 400 to perform a linear motion through the rotating shaft device 500, so that the length of the foot pad 400 extending out of the second part 300 becomes longer.

[0093] When the electronic device 100 is placed on a tabletop, the first part 200 rotates relative to the second part 300, so that the angle between the first part 200 and the second part 300 gradually increases to unfold the electronic device 100. During the unfolding process, the first part 200 drives the foot pad 400 to perform a linear motion through the rotating shaft device 500, so that the length of the foot pad 400 extending out of the electronic device 100 increases, thereby increasing the space between the electronic device 100 and the tabletop, and further improving the heat dissipation capacity of the electronic device 100.

[0094] Figure 3 For Figure 1 is a schematic structural diagram of the electronic device in the closed state, Figure 4 For Figure 1 is a schematic diagram of the electronic device when the unfolding angle is N1°, Figure 5 For Figure 1 is a schematic diagram of the electronic device when the unfolding angle is N°.

[0095] Since the electronic device 100 is a laptop computer, the electronic device 100 has a closed state (e.g., Figure 3 as shown) and an unfolded state (e.g., Figure 4 or Figure 5 as shown). Combining Figure 3 it can be seen that when the electronic device 100 is in the closed state, the included angle between the first part 200 and the first part 200 is 0°, in other words, the unfolding angle of the electronic device 100 is 0°. When the electronic device 100 is in the unfolded state, the included angle between the first part 200 and the second part 300 is greater than 0° and less than or equal to N°, in other words, the range of the unfolding angle of the electronic device 100 is 0 to N°. Wherein, N is greater than 0 and less than 180, for example, N can be 120. In addition, N° can be understood as the maximum unfolding angle of the electronic device 100. For example, in the embodiments of the present application, N° can be 120° (e.g., Figure 5 as shown).

[0096] During the unfolding process of the electronic device 100, there is no limitation on when the rotating shaft device 500 drives the foot pad 400 to move linearly, so that the length of the foot pad 400 extending out of the electronic device 100 increases. Exemplarily, combining Figure 3 and Figure 5 it can be seen that during the process of the unfolding angle of the electronic device 100 changing from 0° to N1°, the rotating shaft device 500 drives the foot pad 400 to move linearly, so that the length of the foot pad 400 extending out of the electronic device 100 gradually increases until the unfolding angle of the electronic device 100 reaches N1° and then stops. Subsequently, combining Figure 4 and Figure 5 it can be seen that the unfolding angle of the electronic device 100 changes from N1° to N°. During this process, the rotating shaft device 500 does not drive the foot pad 400 to move linearly, and the length of the foot pad 400 extending out of the electronic device 100 does not change.

[0097] Of course, in addition to moving linearly during the process of the unfolding angle of the electronic device 100 changing from 0° to N1°, in some embodiments, the foot pad 400 can also move linearly during the process of the unfolding angle of the electronic device 100 changing from N1° to N2°, so that the length of the foot pad 400 extending out of the electronic device 100 increases, where 0° < N1° < N2° < N°. Or in some embodiments, the foot pad 400 can also move linearly during the process of the unfolding angle of the electronic device 100 changing from N1° to N°, so that the length of the foot pad 400 extending out of the electronic device 100 increases, where 0° < N1° < N°. Or in some embodiments, the foot pad 400 can also move linearly during the process of the unfolding angle of the electronic device 100 changing from 0° to N°, so that the length of the foot pad 400 extending out of the electronic device 100 increases.

[0098] In the embodiment of the present application, taking the example that the foot pad 400 moves linearly during the process that the unfolding angle of the electronic device 100 changes from 0° to N1° for illustration.

[0099] Next, in conjunction with the accompanying drawings, the implementation manner of the rotating shaft device 500 provided in the embodiment of the present application will be elaborated.

[0100] Figure 6 It is the first three-dimensional structure schematic diagram of the first rotating shaft device provided in the embodiment of the present application. Figure 7 is Figure 6 the second three-dimensional structure schematic diagram of the rotating shaft device in Figure 8 is Figure 6 the top view structure schematic diagram of the rotating shaft device in Figure 9 is Figure 6 the explosion schematic diagram of the rotating shaft device in

[0101] Refer to Figure 6 As shown, the rotating shaft device 500 in the embodiment of the present application includes a first rotating shaft 10, a second rotating shaft 20 and a link mechanism 30. Among them, the link mechanism 30 includes a first rod 31, a second rod 32 and a third rod 33. The first end of the first rod 31 is movably connected to the first end of the second rod 32, the second end of the first rod 31 is movably connected to the first end of the third rod 33, the third end of the first rod 31 is used for fixedly connecting with the foot pad 400, and the second end of the second rod 32 is connected to the second rotating shaft 20. The first rotating shaft 10 is in transmission connection with the second rotating shaft 20. The first rotating shaft 10 is fixedly connected to the first part 200. The first rotating shaft 10 is used for receiving a driving force. During the rotation of the first rotating shaft 10, the second rotating shaft 20 is used for driving the foot pad 400 to move linearly through the link mechanism 30 under the drive of the first rotating shaft 10.

[0102] Combined with Figure 2 and Figure 3 It can be known that during the unfolding process of the electronic device 100, the first part 200 applies a driving force to the first rotating shaft 10 to make the first rotating shaft 10 rotate. After the first rotating shaft 10 receives the driving force, the first rotating shaft 10 drives the second rotating shaft 20 to rotate. While the second rotating shaft 20 rotates, it drives the second rod 32 to rotate. While the second rod 32 rotates, it drives the first rod 31 to move linearly along the first direction Z. While the first rod 31 moves linearly, it also drives the third rod 33 to rotate through the first rod 31. Since the foot pad 400 is fixedly connected to the first rod 31, the first rod 31 drives the foot pad 400 to move linearly along the first direction Z.

[0103] Refer to Figure 7As shown, the first end of the first rod member 31 is connected to the first end of the second rod member 32, and the second end of the first rod member 31 is connected to the first end of the third rod member 33, such that the structure of the link mechanism 30 is similar to a four-bar linkage structure, thereby improving the reliability and stability of the linear motion of the first rod member 31, and further improving the smoothness and stability of the linear motion of the foot pad 400.

[0104] Since the foot pad 400 is fixedly connected to the first rod member 31, the first rod member 31 can drive the foot pad 400 to perform a linear motion while performing a linear motion, so that the length of the foot pad 400 extending out of the electronic device 100 can be increased, and further the space between the electronic device 100 and the tabletop supporting the electronic device 100 is increased, so as to increase the heat dissipation capacity of the electronic device 100.

[0105] There is no limitation on the specific structure of the first rod member 31 here. Exemplarily, for example Figure 9 As shown, the first rod member 31 may include a body portion 313 and a fixing portion 314. The first end and the second end of the body portion 313 are respectively connected to the third rod member 33 and the fixing portion 314, and the third end of the body portion 313 is connected to the second rod member 32. The fixing portion 314 is used for fixedly connecting with the foot pad 400. Among them, there is no limitation on the specific structure of the body portion 313 here. For example Figure 9 As shown, the body portion 313 may be a rod-shaped structure with a rectangular cross-section. There is no limitation on the specific structure of the fixing portion 314 here. For example Figure 9 As shown, the fixing portion 314 may be a rectangular plate-shaped structure.

[0106] See Figure 6 As shown, the second rotating shaft 20 is fixedly connected to the second end of the second rod member 32. Thus, during the rotation of the second rotating shaft 20, the second rotating shaft 20 will drive the second rod member 32 to rotate around the axis of the second rotating shaft 20, and further the second rod member 32 will drive the first rod member 31 and the third rod member 33 to move. There is no limitation on how the second rotating shaft 20 is fixedly connected to the second rod member 32 here. Exemplarily, the second end of the second rod member 32 may include a fixing hole for the second rotating shaft 20 to be inserted, and the second rotating shaft 20 is in interference fit with the fixing hole.

[0107] In addition to the second rotating shaft 20 being fixedly connected to the third end of the second rod member 32 to drive the second rod member 32 to rotate around the axis of the second rotating shaft 20, in some implementation manners, the rotating shaft device 500 may further include a transmission member (not shown in the figure). The first end and the second end of the transmission member are respectively in transmission connection with the second rotating shaft 20 and the second end of the second rod member 32, and the second rotating shaft 20 drives the second rod member 32 to rotate around the axis of the second rotating shaft 20 through the transmission member. Here, there is no limitation on the specific structure of the transmission member. In some implementation manners, the transmission member may include a first gear and a second gear. The first gear is fixed to the second rotating shaft 20, the second gear is fixed to the second end of the second rod member 32, and the first gear meshes with the second gear.

[0108] Figure 10 is Figure 8 the sectional view at A-A in.

[0109] In order to realize the movable connection between the first rod member 31 and the second rod member 32, in some possible implementation manners, one of the first rod member 31 and the second rod member 32 may be provided with a first strip-shaped hole 311, and a part of the other may be movably disposed inside the first strip-shaped hole 311. For example Figure 7 and Figure 10 as shown, the first strip-shaped hole 311 is provided in the first rod member 31 and a part of the second rod member 32 is movably disposed inside the first strip-shaped hole 311. Of course, the first strip-shaped hole 311 may also be provided in the second rod member 32 and a part of the first rod member 31 is movably disposed inside the first strip-shaped hole 311.

[0110] During the rotation of the second rotating shaft 20, the second rotating shaft 20 drives the second rod member 32 to rotate. The part of the second rod member 32 disposed in the first strip-shaped hole 311 slides along the inner wall of the first strip-shaped hole 311 and abuts against the inner wall of the first strip-shaped hole 311 in the first direction Z (for example Figure 10 as shown), so that the first rod member 31 makes a linear motion in the first direction Z, and thus the first rod member 31 can drive the foot pad 400 to make a linear motion in the first direction Z.

[0111] See Figure 7 as shown, the first rod member 31 is composed of a fixing part 314 and a body part 313, and the first strip-shaped hole 311 is provided in the body part 313. In addition, along the second direction Y, the first strip-shaped hole 311 may also penetrate through the body part 313, which can simplify the structure of the first rod member 31 and also reduce the processing difficulty of the first rod member 31.

[0112] There is no limitation on the specific structure of the second rod member 32 here. Exemplarily, as Figure 9As shown, the second rod member 32 may include a first main body portion 322 and a first branch portion 321. One end of the first main body portion 322 is fixedly connected to the second rotating shaft 20, and the other end of the second main body portion 332 is fixedly connected to the first branch portion 321. A part of the first branch portion 321 is disposed inside the first strip-shaped hole 311 (see Figure 7 as shown). Of course, the first branch portion 321 may also be disposed inside the first strip-shaped hole 311.

[0113] Here, no limitation is imposed on the specific structure of the first branch portion 321. Exemplarily, for example Figure 9 as shown, the first branch portion 321 may be a cylindrical structure, which can reduce the resistance between the first branch portion 321 and the first strip-shaped hole 311. Of course, the first branch portion 321 may also be a columnar structure with a polygonal cross-section.

[0114] Here, no limitation is imposed on the specific shape of the second rod member 32. Exemplarily, as Figure 9 shown, the other end of the first main body portion 322 is connected to the middle of the first branch portion 321, so that the shape of the second rod member 32 may be similar to a "T" shape. Of course, the second rod member 32 may also be other shapes. For example, the shape of the second rod member 32 may also be similar to an "L" shape.

[0115] In order to achieve the movable connection between the first rod member 31 and the third rod member 33, in some possible implementation manners, one of the first rod member 31 and the third rod member 33 may be provided with a second strip-shaped hole 312, and a part of the other may be movably disposed inside the second strip-shaped hole 312. For example Figure 7 and Figure 10 as shown, the second strip-shaped hole 312 is provided in the first rod member 31 and a part of the third rod member 33 is movably disposed inside the second strip-shaped hole 312. Of course, the second strip-shaped hole 312 may also be provided in the third rod member 33 and a part of the first rod member 31 is movably disposed inside the second strip-shaped hole 312.

[0116] During the rotation of the second rotating shaft 20, the second rotating shaft 20 drives the first rod member 31 to perform a linear motion along the first direction Z through the second rod member 32. At the same time, the part of the third rod member 33 disposed in the second strip-shaped hole 312 slides along the inner wall of the second strip-shaped hole 312 and abuts against the inner wall of the second strip-shaped hole 312, which can improve the stability and reliability of the first rod member 31 during movement. In addition, when the third rod member 33 is connected to the second rod member 32 through the fourth rod member 34, the third rod member 33 can also drive the first rod member 31 to perform a linear motion through the second strip-shaped hole 312 to improve the smoothness and reliability of the movement of the first rod member 31.

[0117] See Figure 7As shown, the first rod member 31 is composed of a fixing portion 314 and a body portion 313, and a second elongated hole 312 is provided in the body portion 313. Additionally, along the second direction Y, the second elongated hole 312 may also penetrate through the body portion 313, which can simplify the structure of the first rod member 31 and also reduce the processing difficulty of the first rod member 31.

[0118] For example Figure 10 As shown, along the first direction Z, the first elongated hole 311 and the second elongated hole 312 are arranged at the same height. Of course, the first elongated hole 311 and the second elongated hole 312 may also be arranged at different heights. Correspondingly, whether the first elongated hole 311 and the second elongated hole 312 are arranged at the same height or at different heights does not affect the linear movement of the first rod member 31. When the first elongated hole 311 and the second elongated hole 312 are arranged at the same height, the design difficulty of the link mechanism 30 can be reduced.

[0119] Regarding the specific structure of the third rod member 33, no limitation is imposed here. Exemplarily, for example Figure 9 As shown, the third rod member 33 may include a second branch portion 331 and a second main body portion 332. One end of the second main body portion 332 is connected to the second branch portion 331, and a part of the second branch portion 331 is disposed inside the second elongated hole 312. Of course, the second branch portion 331 may also be disposed inside the second elongated hole 312.

[0120] Among them, regarding the specific structure of the second branch portion 331, no limitation is imposed here. Exemplarily, for example Figure 9 As shown, the second branch portion 331 may be a cylindrical structure, which can reduce the resistance between the second branch portion 331 and the second elongated hole 312. Of course, the second branch portion 331 may also be a columnar structure with a polygonal cross-section.

[0121] Regarding the specific shape of the third rod member 33, no limitation is imposed here. Exemplarily, as Figure 9 As shown, the other end of the second main body portion 332 is connected to the middle of the second branch portion 331, so that the shape of the third rod member 33 may be similar to a "T" shape. Of course, the third rod member 33 may also be of other shapes. For example, the shape of the third rod member 33 may also be similar to an "L" shape.

[0122] In some possible implementation manners, the link mechanism 30 further includes at least one fourth rod member 34, for example Figure 7 As shown, the number of the fourth rod members 34 is two. Of course, the number of the fourth rod members 34 may also be one. At least one fourth rod member 34 is disposed on at least one side of the opposite sides of the first rod member 31, for example Figure 8As shown, along the second direction Y, a fourth rod member 34 is respectively arranged on the opposite sides of the first rod member 31, and each fourth rod member 34 is arranged at an interval from the first rod member 31. Along the third direction X, the opposite ends of each fourth rod member 34 are respectively rotatably connected to the second rod member 32 and the third rod member 33 (as Figure 8 shown), and the axis of rotation of the fourth rod member 34 connected to the second rod member 32 is parallel to the axis of rotation of the fourth rod member 34 connected to the third rod member 33.

[0123] For example Figure 8 as shown, when the fourth rod members 34 are respectively arranged on the opposite sides of the first rod member 31, the second rod member 32, the third rod member 33 and the two fourth rod members 34 can form a stable parallelogram structure, which can further improve the smoothness and stability of the movement of the first rod member 31. In addition, when the fourth rod member 34 is arranged on one side or both sides of the first rod member 31, the second rod member 32 and the third rod member 33 can be connected through the fourth rod member 34, so that the second rod member 32 can drive the third rod member 33 to rotate through the fourth rod member 34, and thus the third rod member 33 can also drive the first rod member 31 to perform a linear motion, and further the overall force on the first rod member 31 can be made uniform so that the first rod member 31 moves more smoothly and smoothly.

[0124] Regarding the specific structure of the fourth rod member 34, no limitation is made here. For example Figure 9 as shown, the fourth rod member 34 can be a rod-shaped structure with a rectangular cross-section.

[0125] Regarding how the fourth rod member 34 is rotatably connected to the second rod member 32 and the third rod member 33, no limitation is made here. Exemplarily, the fourth rod member 34 can be rotatably connected to the second rod member 32 or the third rod member 33 through a pin.

[0126] Combined with Figure 8 and Figure 9 it can be known that since the second rod member 32 is composed of the first main body portion 322 and the first branch portion 321, the opposite ends of the first branch portion 321 can be respectively fixedly connected to one end of the two fourth rod members 34, and a part of the first branch portion 321 is arranged inside the first strip-shaped hole 311.

[0127] Combined with Figure 8 and Figure 9 it can be known that since the third rod member 33 is composed of the second main body portion 332 and the second branch portion 331, the opposite ends of the second branch portion 331 can be respectively fixedly connected to the other end of the two fourth rod members 34, and a part of the second branch portion 331 is arranged inside the second strip-shaped hole 312.

[0128] See Figure 6As shown, the rotating shaft device 500 further includes a supporting member 40. The second ends of the first rotating shaft 10, the second rotating shaft 20, and the third rod member 33 can be respectively connected to the supporting member 40, such that the second rotating shaft 20 cooperates with the first rotating shaft 10 and the second rod member 32 respectively, and the first rod member 31 cooperates with the second rod member 32 and the third rod member 33 respectively. In addition, the supporting member 40 can also be used for fixedly connecting with the second housing 320 to fix the rotating shaft device 500 inside the second part 300.

[0129] There is no limitation on the specific structure of the supporting member 40 here. Exemplarily, referring to Figure 7 As shown, the supporting member 40 can include a first supporting frame 44 and a second supporting frame 45. The first supporting frame 44 and the second supporting frame 45 are detachably connected, which can reduce the manufacturing cost of the supporting member 40. In addition, it can also reduce the difficulty of the cooperation between the first rotating shaft 10, the second rotating shaft 20, the second rod member 32, and the third rod member 33 and the supporting member 40.

[0130] It should be noted that the supporting member 40 can also be removed. In this case, the first rotating shaft 10, the second rotating shaft 20, and the third rod member 33 can also be installed on the second housing 320, and it can also make the first rotating shaft 10, the second rotating shaft 20, and the link mechanism 30 cooperate with each other.

[0131] In order to guide the first rod member 31 to move linearly, in some possible implementation manners, for example Figure 6 or Figure 7 As shown, the supporting member 40 can further include a guiding portion 41. Wherein, the guiding portion 41 is connected to the first rod member 31. During the rotation of the second rotating shaft 20, the guiding portion 41 is used to make the first rod member 31 move linearly.

[0132] Correspondingly, during the process of the second rod member 32 driving the first rod member 31 to move, through the guiding of the first rod member 31 by the guiding portion 41, the first rod member 31 can move linearly along the first direction Z, so that the length of the foot pad 400 extending out of the electronic device 100 can change.

[0133] It should be noted that when the supporting member 40 is removed from the rotating shaft device 500, in some implementation manners, the rotating shaft device 500 can further include a guiding member (not shown in the figure). The guiding member is used to guide the first rod member 31 to move linearly during the rotation of the second rotating shaft 20, and the guiding member can be connected to the second housing 320. Wherein, the connection structure between the guiding member and the first rod member 31 can be similar to the connection structure between the guiding portion 41 and the first rod member 31.

[0134] Combined with Figure 7 As shown, a guiding portion 41 is respectively provided on the first supporting frame 44 and the second supporting frame 45. Of course, a guiding portion 41 can also be provided on one of the first supporting frame 44 and the second supporting frame 45.

[0135] Figure 11 is Figure 9 a top view structural schematic diagram of the first rod member in. There is no limitation here on how the guiding portion 41 is connected to the first rod member 31 to guide the first rod member 31 to move linearly. Exemplarily, one of the guiding portion 41 and the first rod member 31 may include a guiding hole 411, and the other may include a protruding portion 315 at least partially disposed in the guiding hole 411. For example, the guiding hole 411 may be provided in the guiding portion 41 (as shown in Figure 10 ), and the first rod member 31 has a protruding portion 315 (as shown in Figure 11 ). Of course, the guiding hole 411 may also be provided in the first rod member 31 and the protruding portion 315 may also be provided in the guiding portion 41.

[0136] Combined with Figure 10 it can be seen that during the process of the second rod member 32 driving the first rod member 31 to move, the protruding portion 315 slides in cooperation with the inner wall of the guiding hole 411. Thus, the inner wall of the guiding hole 411 can guide the protruding portion 315 to move linearly along the first direction Z, and further, the guiding portion 41 can guide the first rod member 31 to move linearly. In addition, providing the guiding hole 411 in the guiding portion 41 can simplify the structure of the support member 40.

[0137] Among them, the guiding portion 41 may be provided with a plurality of guiding holes 411, and the first rod member 31 includes a plurality of protruding portions 315, and each protruding portion 315 corresponds to a guiding hole 411. For example, as shown in Figure 10 , the guiding portion 41 is provided with two guiding holes 411 arranged at intervals along the third direction X, and each guiding hole 411 corresponds to a protruding portion 315. Correspondingly, by cooperating a plurality of guiding holes 411 with a plurality of protruding portions 315 to guide the first rod member 31 to move linearly, the accuracy of the linear movement of the first rod member 31 can be improved. Among them, the first direction Z, the second direction Y, and the third direction X are perpendicular to each other.

[0138] For example, as shown in Figure 7 , the number of the guiding portions 41 may be two, and the first rod member 31 is disposed between the two guiding portions 41. Of course, the number of the guiding portions 41 may also be one. Therefore, the number of the guiding portions 41 may be one or two, and both can guide the first rod member 31 to move linearly along the first direction Z. However, by guiding the first rod member 31 to move linearly with two guiding portions 41, not only can the guiding effect of guiding the first rod member 31 be further improved, but also the first rod member 31 can be prevented from moving in the arrangement direction of the two guiding portions 41 (such as the Y direction in Figure 8 ), and the reliability of the movement of the first rod member 31 can be further improved.

[0139] It should be noted that when the number of the guiding parts 41 is two, each guiding part 41 may be provided with a plurality of guiding holes 411, or each guiding part 41 may also be provided with one guiding hole 411, or one of the two guiding parts 41 may be provided with one guiding hole 411 and the other may be provided with two guiding holes 411. In addition, when the number of the guiding parts 41 is one, the guiding part 41 may be provided with one or more guiding holes 411.

[0140] For example Figure 7 As shown, the guiding part 41 may also be arranged between the second rod member 32 and the third rod member 33. The space between the second rod member 32 and the third rod member 33 can be utilized to arrange the guiding part 41, which can improve the integration degree of the rotating shaft device 500 and is beneficial to the miniaturization of the rotating shaft device 500. Of course, the guiding part 41 may not be arranged between the second rod member 32 and the third rod member 33, and the guiding part 41 may also guide the first rod member 31 to move linearly.

[0141] For example Figure 7 As shown, the guiding part 41 may also be arranged between two fourth rod members 34. The space between the two fourth rod members 34 can be utilized to arrange the limiting part, which can reduce the space required for arranging the rotating shaft device 500 and can reduce the arrangement difficulty of the rotating shaft device 500. Of course, the guiding part 41 may not be arranged between the two fourth rod members 34, and the guiding part 41 may also guide the first rod member 31 to move linearly.

[0142] In some embodiments, for example Figure 9 As shown, the bearing member 40 may also be provided with an avoidance notch 51 for avoiding the first rotating shaft 10, the second rotating shaft 20, the first rod member 31 and the second rod member 32.

[0143] During the linear movement of the first rod member 31, by avoiding the first rotating shaft 10, the second rotating shaft 20, the first rod member 31 and the second rod member 32 through the avoidance notch 51, the interference of the bearing member 40 with the movement of the first rotating shaft 10, the second rotating shaft 20, the first rod member 31 and the second rod member 32 can be avoided, so that the integration degree of the rotating shaft device 500 can be improved, and further it is beneficial to the miniaturization of the rotating shaft device 500.

[0144] In some embodiments, the bearing member 40 may also be provided with at least one of a first groove 52, a second groove 53, a third groove 54 and a fourth groove 55. For example Figure 9 As shown, the bearing member 40 may be provided with a first groove 52, a second groove 53, a third groove 54 and a fourth groove 55. Among them, the first groove 52 is used for avoiding the first rod member 31, the second groove 53 is used for avoiding the second rod member 32, the third groove 54 is used for avoiding the third rod member 33, and the fourth groove 55 is used for avoiding the fourth rod member 34.

[0145] During the linear motion of the first rod 31, by providing at least one of a first groove 52, a second groove 53, a third groove 54, and a fourth groove 55 on the support member 40, it is possible to avoid the first rod 31, the second rod 32, the third rod 33, and the fourth rod 34 from being unable to move due to the interference of the support member 40. Thus, on the premise of satisfying the movement of the linkage mechanism 30, the integration degree of the rotating shaft device 500 can be improved, which is conducive to the miniaturization of the rotating shaft device 500.

[0146] In some embodiments, the support member 40 can also be used for rotatably connecting to at least one of the first rotating shaft 10, the second rotating shaft 20, and the third rod 33. For example Figure 7 As shown, both ends of the first rotating shaft 10 are rotatably connected to the support member 40, both ends of the second rotating shaft 20 are rotatably connected to the support member 40, and the third rod 33 is rotatably connected to the support member 40. By rotatably connecting the support member 40 to the first rotating shaft 10, the second rotating shaft 20, and the third rod 33, the utilization rate of the support member 40 can be improved, thereby reducing the number of parts of the rotating shaft device 500 and simplifying the structure of the rotating shaft device 500.

[0147] See Figure 7 As shown, the support member 40 can include a first support 44 and a second support 45, and the first support 44 and the second support 45 are detachably connected. Among them, the third rod 33 can be rotatably connected to the first support 44 or the second support 45. Both ends of the first rotating shaft 10 are rotatably connected to the first support 44 and the second support 45 respectively. Both ends of the second rotating shaft 20 are rotatably connected to the first support 44 and the second support 45 respectively.

[0148] In some embodiments, for example Figure 7 As shown, the support member 40 can further include a first stop portion 42 (see Figure 9 As shown), and the first rotating shaft 10 further includes a second stop portion 13 (see Figure 12 As shown). Among them, during the rotation of the first rotating shaft 10, by abutting the first stop portion 42 against the second stop portion 13, the rotation of the first rotating shaft 10 can be restricted, so that the unfolding angle of the electronic device 100 is the maximum unfolding angle.

[0149] Regarding the specific structure of the second stop portion 13, no limitation is made here. Exemplarily, for example Figure 7 As shown, the second stop portion 13 can be a strip-shaped structure extending along the axial direction of the first rotating shaft 10.

[0150] Figure 12 For Figure 9 is a schematic three-dimensional structure diagram of the cooperation between the first rotating shaft and the second rotating shaft. See Figure 12As shown, the first rotating shaft 10 may include a first tooth portion 11, and the second rotating shaft 20 may include a second tooth portion 21. The first tooth portion 11 is used to mesh with the second tooth portion 21. During the meshing process of the first tooth portion 11 and the second tooth portion 21, the first rotating shaft 10 can drive the second rotating shaft 20 to rotate, and the second rotating shaft 20 drives the first rod 31 to move linearly through the second rod 32.

[0151] Along the circumferential direction of the first rotating shaft 10, a partial area of the first rotating shaft 10 may be provided with the first tooth portion 11 (for example Figure 12 as shown). In other words, the multiple first tooth portions 11 in the first rotating shaft 10 do not form a complete gear structure. Along the circumferential direction of the second rotating shaft 20, a partial area of the second rotating shaft 20 is provided with the second tooth portion 21, and the multiple second tooth portions 21 in the second rotating shaft 20 do not form a complete gear structure.

[0152] Therefore, during the meshing process of the first tooth portion 11 and the second tooth portion 21, when the first rotating shaft 10 rotates, it can drive the second rotating shaft 20 to rotate, so that the second rotating shaft 20 drives the foot pad 400 to move linearly through the link mechanism 30, so that the length of the foot pad 400 extending out of the electronic device 100 increases. During the process when the first tooth portion 11 and the second tooth portion 21 are not meshed, when the first rotating shaft 10 rotates, it will not drive the second rotating shaft 20 to rotate either. At this time, the length of the part of the foot pad 400 extending out of the electronic device 100 remains unchanged.

[0153] It should be noted that in addition to the way shown in Figure 10 to realize the intermittent driving of the second rotating shaft 20 by the first rotating shaft 10, in some embodiments, the multiple first tooth portions 11 in the first rotating shaft 10 may also form a complete gear structure. Correspondingly, although the multiple second tooth portions 21 in the second rotating shaft 20 do not form a complete gear structure, the first tooth portion 11 and the second tooth portion 21 can be separated during the rotation of the first rotating shaft 10 to avoid the rotation of the second rotating shaft 20. Or in some embodiments, although the multiple first tooth portions 11 in the first rotating shaft 10 do not form a complete gear structure, the multiple second tooth portions 21 in the second rotating shaft 20 may also form a complete gear structure, and the first tooth portion 11 and the second tooth portion 21 can be separated during the rotation of the first rotating shaft 10 to avoid the rotation of the second rotating shaft 20.

[0155] Combined with Figure 13 As can be seen, when the unfolding angle of the electronic device 100 is 0°, the first tooth part 11 meshes with the second tooth part 21. Therefore, during the process of the unfolding angle of the electronic device 100 changing from 0° to N1°, combined with Figures 13 to 17 As can be seen, the first rotating shaft 10 can drive the second rotating shaft 20 to rotate, so that the second rotating shaft 20 can drive the foot pad 400 to perform a linear motion through the link mechanism 30, increasing the length of the foot pad 400 extending out of the electronic device. When the unfolding angle of the electronic device 100 becomes N1°, the first tooth part 11 and the second tooth part 21 are not meshed, or it can be said that the first tooth part 11 and the second tooth part are disengaged from meshing. Therefore, during the process of the unfolding angle of the electronic device 100 changing from N1° to N°, the first rotating shaft 10 does not drive the second rotating shaft 20 to rotate, so that the length of the foot pad 400 extending out of the electronic device 100 remains unchanged.

[0157] Combined with the above Figure 12 shown, and referring to Figure 18 shown, the first rotating shaft 10 may further include a first convex part 12, and the second rotating shaft 20 may further include a second convex part 22. Wherein, along the third direction X, the projection of the first convex part 12 overlaps with the projection of the second convex part 22. The first convex part 12 may be provided with a first notch 121, which can avoid the first convex part 12 from touching the second convex part 22 during the rotation of the first rotating shaft 10 driving the second rotating shaft 20 to ensure the rotation of the first rotating shaft 10 and the second rotating shaft 20, or it can be understood that the first notch 121 can be used to avoid the second convex part 22.

[0158] During the process of the unfolding angle of the electronic device 100 changing from 0° to N1°, in combination with Figure 18 and Figure 19 it can be known that the second convex portion 22 can be partially disposed inside the first notch 121, so that the first convex portion 12 can avoid the second convex portion 22, so as to prevent the first rotating shaft 10 and the second rotating shaft 20 from being unable to rotate due to their contact.

[0159] During the process of the unfolding angle of the electronic device 100 changing from N1° to N°, since the first tooth portion 11 and the second tooth portion 21 are not engaged, the second rotating shaft 20 may reverse, resulting in the length of the foot pad 400 extending out of the electronic device 100 becoming shorter, making the heat dissipation space of the electronic device 100 smaller, which is not conducive to the heat dissipation of the electronic device 100. Among them, the reverse rotation of the second rotating shaft 20 can be understood as the direction opposite to the direction in which the first rotating shaft 10 drives the second rotating shaft 20 to rotate. For example, as shown in Figure 15 If the first rotating shaft 10 drives the second rotating shaft 20 to rotate clockwise, then the reverse rotation direction of the second rotating shaft 20 is counterclockwise. Therefore, it is necessary to prevent the second rotating shaft 20 from rotating during the process of the unfolding angle of the electronic device 100 changing from N1° to N°, so as to ensure that the length of the foot pad 400 extending out of the electronic device 100 does not change.

[0160] Exemplarily, as shown in Figure 18 the second convex portion 22 can also be provided with a second notch 221. During the process when the first rotating shaft 10 does not drive the second rotating shaft 20 to rotate, the second notch 221 is used to cooperate with the first convex portion 12 to prevent the second rotating shaft 20 from rotating relative to the first rotating shaft 10. In other words, by the cooperation of the second notch 221 and the first convex portion 12, it is possible to achieve the rotation of the first rotating shaft 10 while the second rotating shaft 20 does not rotate.

[0161] In combination with Figure 19 it can be known that when the unfolding angle of the electronic device 100 is N1°, a part of the first convex portion 12 is disposed inside the second notch 221 and is in sliding cooperation with the inner wall of the second notch 221. The second notch 221 and the first convex portion 12 can form a limiting structure, which can achieve the rotation of the first rotating shaft 10 while the second rotating shaft 20 does not rotate, thereby avoiding the retraction of the first rod 31 caused by the reverse rotation of the second rotating shaft 20, and further enabling the length of the foot pad 400 extending out of the electronic device 100 to remain unchanged. In combination with Figure 19 and Figure 20 it can be known that during the process of the unfolding angle of the electronic device 100 changing from N1° to N°, that is, during the process when the first rotating shaft 10 does not drive the second rotating shaft 20 to rotate, through the limiting structure formed by the second notch 221 and the first convex portion 12, it is possible to prevent the second rotating shaft 20 from rotating relative to the first rotating shaft 10, and avoid the shortening of the length of the foot pad 400 extending out of the electronic device 100.

[0162] It can be understood that when the electronic device 100 is placed on the tabletop, the foot pads 400 are in contact with the tabletop, causing the foot pads 400 to tend to contract towards the inside of the electronic device 100. During the process of the unfolding angle of the electronic device 100 changing from N1° to N°, referring to Figure 19 and Figure 20 As shown, if the foot pads 400 contract towards the inside of the electronic device 100, then the foot pads 400 will drive the second rotating shaft 20 to rotate clockwise through the link mechanism 30, causing the second rotating shaft 20 to rotate in the reverse direction, which will make the space between the electronic device 100 and the tabletop smaller. However, since the second notch 221 and the first convex portion 12 form a limiting structure, when the second rotating shaft 20 rotates in the reverse direction, the second convex portion 22 will be in contact with the first convex portion 12, so that the second rotating shaft 20 cannot rotate in the reverse direction, and thus the foot pads 400 will not contract, ensuring that the size of the space between the electronic device 100 and the tabletop remains basically unchanged.

[0163] Combined with Figure 18 and Figure 19 It can be known that during the process of the unfolding angle of the electronic device 100 changing from 0° to N1°, the first convex portion 12 can also be avoided by the second notch 221, preventing the first rotating shaft 10 and the second rotating shaft 20 from being unable to rotate due to interference between the first convex portion 12 and the second convex portion 22.

[0164] Referring to Figure 18 As shown, the second notch 221 can be an arc-shaped notch, so that the inner wall of the second notch 221 can be adapted to the outer wall of the first convex portion 12, thereby restricting the rotation of the second rotating shaft 20 while the first rotating shaft 10 rotates.

[0165] Referring to Figure 19 As shown, the inner wall of the second notch 221 can be in sliding fit with the outer wall of the first convex portion 12. On the premise that the first convex portion 12 and the second notch 221 form a limiting structure to prevent the second rotating shaft 20 from rotating, it can be ensured that the first rotating shaft 10 can rotate relative to the second rotating shaft 20. Of course, in order to further improve the smoothness and quietness of the sliding contact between the inner wall of the second notch 221 and the first convex portion 12, a gap for accommodating a lubricating medium can also be provided between the first convex portion 12 and the inner wall of the second notch 221. For example, the lubricating medium can be lubricating oil.

[0166] In some possible implementation manners, for example Figure 20 As shown, the second convex portion 22 can also be provided with a third notch 222. Among them, during the rotation of the second rotating shaft 20, combined with Figure 6 and Figure 7It can be seen that the third notch 222 is used to avoid the first rod 31, which can ensure the normal operation of the second rotating shaft 20 and the first rod 31. In addition, the distance between the second rotating shaft 20 and the first rod 31 can be reduced, thereby reducing the size of the rotating shaft device 500 in the third direction X, which is conducive to the miniaturization of the rotating shaft device 500.

[0167] Figure 23 For Figure 8 the left view schematic diagram of the rotating shaft device in

[0168] In some possible implementation manners, referring to Figure 7 as shown, the first rotating shaft 10 may further include a first shaft body portion 14, and the bearing member 40 may include a mating portion 43, and the mating portion 43 defines a mating hole 431. Wherein, one end of the first shaft body portion 14 is disposed in the mating hole 431 and is in interference fit with the mating portion 43 (as Figure 23 shown), so that there is a certain interference amount between the bearing member 40 and the first rotating shaft 10, and the first rotating shaft 10 will not rotate when the first rotating shaft 10 does not receive an external force. The other end of the first shaft body portion 14 is used for fixedly connecting with the first part 200, so that the first rotating shaft 10 drives the second rotating shaft 20 to rotate under the drive of the first part 200.

[0169] Since the mating portion 43 is in interference fit with the first shaft body portion 14, there is a torsion force that keeps the first rotating shaft 10 stationary between the first rotating shaft 10 and the mating portion 43. Therefore, when the electronic device 100 is unfolded and no external force is applied to change the unfolding angle, the included angle between the first part 200 and the second part 300 can remain unchanged to ensure the normal use of the electronic device 100.

[0170] Referring to Figure 7 as shown, the first shaft body portion 14 may further include a spline portion 15, and the spline portion 15 is used for being inserted into the inside of the first part 200, so that the first rotating shaft 10 is fixedly connected with the first part 200 by riveting.

[0171] Referring to Figure 7 as shown, the bearing member 40 may further include two first supporting portions 46, and the two first supporting portions 46 are respectively sleeved on the outer wall of the first shaft body portion 14 and are respectively rotationally connected with the first shaft body portion 14. The two first supporting portions 46 are arranged at intervals along the axial direction of the first rotating shaft 10. Thus, the first rotating shaft 10 can be rotationally connected to the bearing member 40, and further the number of parts of the rotating shaft device 500 can be reduced to simplify the structure of the rotating shaft device 500.

[0172] Referring to Figure 7As shown, the support member 40 may further include two second support portions 47, and the second rotating shaft 20 may further include a second shaft body portion 23. The two second support portions 47 are respectively rotatably connected to opposite ends of the second shaft body portion 23, so that the second rotating shaft 20 can be rotatably connected to the support member 40, thereby reducing the number of parts of the rotating shaft device 500 to simplify the structure of the rotating shaft device 500.

[0173] Figure 24 FIG. 4 is a schematic structural diagram of a second rotating shaft device provided by an embodiment of the present application. Figure 25 is Figure 24 an exploded schematic diagram of the torsion assembly in FIG. Figure 26 is Figure 24 a three-dimensional structural schematic diagram of the connecting member in FIG.

[0174] Figure 24 Different from Figure 6 is that the torsion implementation scheme of the first rotating shaft 10 and the support member 40 is different, and the connection manner between the first rotating shaft 10 and the first part 200 is different. Specifically, for example Figure 24 As shown in FIG. 5, the rotating shaft device 500 may further include a torsion assembly 60. Among them, as Figure 25 shown in FIG. 6, the torsion assembly 60 may include a disc spring 61 and a fixing member 62. The disc spring 61 and the fixing member 62 are respectively sleeved on the first rotating shaft 10. The disc spring 61 is located between the fixing member 62 and the support member 40 and abuts against the fixing member 62 and the support member 40 respectively. When the first rotating shaft 10 rotates, the disc spring 61 will generate frictional force due to being squeezed, thereby increasing the torsion, and further keeping the unfolding angle of the electronic device 100 unchanged.

[0175] Among them, the number of the disc springs 61 may be one or more. For example Figure 25 as shown in FIG. 7, the number of the disc springs 61 is five. Of course, the number of the disc springs 61 may also be more or less than five. In addition, when the number of the disc springs 61 is multiple, the multiple disc springs 61 are arranged between the fixing member 62 and the support member 40.

[0176] Among them, no limitation is imposed on the specific structure of the fixing member 62. Exemplarily, as Figure 25 shown in FIG. 8, the fixing member 62 may be a locknut for sleeving on the first rotating shaft 10 and being threadedly connected to the first rotating shaft 10.

[0177] For example Figure 25 as shown in FIG. 9, the torsion assembly 60 may further include two gaskets 63. One gasket 63 is arranged between the fixing member 62 and the disc spring 61, and the other gasket 63 is arranged between the disc spring 61 and the support member 40.

[0178] Combined with Figure 25 it can be seen that the rotating shaft device 500 may further include a connecting member 70. Among them, for exampleFigure 24 As shown, the other end of the first rotating shaft 10 is fixedly connected to the first part 200 through a connecting member 70. Specifically, referring to Figure 2 it can be known that the rotating shaft device 500 is arranged inside the second part 300, the supporting member 40 is fixedly connected to the second housing 320, and the other end of the first rotating shaft 10 is fixedly connected to the first housing 220 through a connecting member 70.

[0179] There is no limitation on the specific structure of the connecting member 70 here. Exemplarily, as Figure 26 shown, the connecting member 70 can be an L-shaped plate structure. One end of the connecting member 70 is fixedly connected to the other end of the first rotating shaft 10, and the other end of the connecting member 70 can be fixedly connected to the first part 200 through screws.
