AI Technical Summary
The existing rotating mechanism has poor door panel movement accuracy during use, resulting in inaccurate folding of electronic devices.
A rotating mechanism is adopted, including a base, a first door panel, a first swing arm, and a first connecting member. The first connecting member is prevented from moving in a specific direction, ensuring that the position where it intersects with the rotation axis between the first swing arm and the first door panel does not move, thereby improving the motion accuracy.
This effectively improves the precision of the door panel during rotation, avoids wobbling, and ensures a more accurate folding process for electronic devices.

Rotating mechanism and electronic device TECHNICAL FIELD
[0001] Embodiments of the present application relate to the technical field of electronic devices, and in particular to a rotating mechanism and an electronic device. BACKGROUND
[0002] With the development of folding screen technology, electronic devices with folding screens have become a hot technology. The existing folding methods are divided into inner folding and outer folding, that is, the screen is folded on the inside or the outside.
[0003] In order to facilitate the folding of the electronic device, a rotating mechanism with folding function is generally provided on the electronic device.
[0004] However, the rotating mechanism in the related art has poor motion precision of the door plate during use.
[0005] SUMMARY
[0006] Embodiments of the present application provide a rotating mechanism and an electronic device, which can improve the motion precision of the door plate.
[0007] To solve the above technical problems, in a first aspect, the present application provides a rotating mechanism, comprising: a base, a first door plate, a first swing arm and a first connecting piece;
[0008] One end of the first swing arm is rotationally connected with the base, the other end of the first swing arm is rotationally connected with one end of the first connecting piece, and the other end of the first connecting piece is rotationally connected with the first door plate.
[0009] During rotation of the first swing arm relative to the base, the first connecting piece drives the first door plate to rotate relative to the base, and the first connecting piece is hindered from moving in the first direction and the second direction, wherein the first direction intersects a first rotation axis between the first swing arm and the first connecting piece, and the second direction intersects a second rotation axis between the first connecting piece and the first door plate.
[0010] The rotating mechanism provided by the embodiments of the present application can drive the first door panel to rotate relative to the base through the first connecting piece during the rotation of the first swing arm relative to the base. During the rotation, the first connecting piece cannot move in the intersecting line direction of the first rotation axis between the first swing arm and the first connecting piece, and cannot move in the intersecting line direction of the second rotation axis between the first connecting piece and the first door panel, because the first connecting piece is hindered from moving in the first direction and the second direction. Thus, the first connecting piece cannot move in the intersecting line direction of the first rotation axis on the first swing arm during the rotation of the first connecting piece relative to the first swing arm, and only rotation exists between the first connecting piece and the first swing arm, so that the first connecting piece cannot shake relative to the first swing arm. Similarly, the first connecting piece cannot move in the intersecting line direction of the second rotation axis on the first door panel during the rotation of the first connecting piece relative to the first door panel, and only rotation exists between the first connecting piece and the first door panel, so that the first connecting piece cannot shake relative to the first door panel, thereby effectively improving the accuracy of the first door panel during rotation.
[0011] In one of the embodiments, the first connecting piece comprises a first transmission piece.
[0012] One end of the first transmission piece is rotationally connected to one end of the first swing arm away from the base, and the other end of the first transmission piece is rotationally connected to the side of the first door panel facing the first swing arm.
[0013] The first transmission piece is hindered from moving in the first direction and the second direction. Thus, the first swing arm and the first door panel can be connected through the first transmission piece.
[0014] In one of the embodiments, the first connecting piece further comprises a first pin shaft, the first pin shaft is arranged on the first swing arm, and the first pin shaft is rotationally connected to the first transmission piece; or,
[0015] The first pin shaft is arranged on the first transmission piece, and the first pin shaft is rotationally connected to the first swing arm; or,
[0016] One end of the first pin shaft is rotationally connected to the first swing arm, and the other end of the first pin shaft is rotationally connected to the first transmission piece. Thus, the first swing arm and the first transmission piece can be conveniently connected through the first pin shaft.
[0017] In one of the embodiments, when the first pin shaft is arranged on the first swing arm, the first pin shaft is fixedly connected to the first swing arm. Since the first pin shaft is fixed on the first swing arm, the first pin shaft and the first swing arm can be prevented from shaking.
[0018] In one of the embodiments, the first pin shaft is fixedly connected with the first transmission member when the first pin shaft is arranged on the first transmission member. Since the first pin shaft is fixed on the first transmission member, the first pin shaft and the first transmission member can be prevented from shaking.
[0019] In one of the embodiments, the first swing arm is provided with a first shaft hole at one end away from the base, one end of the first pin shaft is rotatably connected with the first swing arm through the first shaft hole, and the other end of the first pin shaft is rotatably connected with the first transmission member.
[0020] The first pin shaft is prevented from moving in any radial direction of the first shaft hole.
[0021] In this way, the first pin shaft can be used to connect the first transmission member and the first swing arm. Since the first pin shaft is prevented from moving in any radial direction of the first shaft hole, i.e. the first pin shaft cannot move in any radial direction relative to the first shaft hole, the first pin shaft cannot shake relative to the first shaft hole, and the first pin shaft can only rotate relative to the first shaft hole under the limitation of the first shaft hole, thereby improving the transmission precision between the first swing arm and the first pin shaft.
[0022] In one of the embodiments, the first transmission member is provided with a second shaft hole, and the other end of the first pin shaft is rotatably connected with the first transmission member through the second shaft hole.
[0023] The first pin shaft is prevented from moving in any radial direction of the second shaft hole. In this way, the connection between the first pin shaft and the first transmission member is facilitated. Since the first pin shaft is prevented from moving in any radial direction of the second shaft hole, i.e. the first pin shaft cannot move in any radial direction relative to the second shaft hole, the first pin shaft cannot shake relative to the second shaft hole, and the first pin shaft can only rotate relative to the second shaft hole under the limitation of the second shaft hole, thereby improving the transmission precision between the first pin shaft and the first transmission member.
[0024] In one of the embodiments, the diameter of one end of the first pin shaft is equal to the diameter of the first shaft hole. In this way, the first pin shaft can be effectively prevented from shaking in the first shaft hole.
[0025] In one of the embodiments, the diameter of the other end of the first pin shaft is equal to the diameter of the second shaft hole. In this way, the first pin shaft can be effectively prevented from shaking in the second shaft hole.
[0026] In one of the embodiments, the first connecting member further comprises a second pin shaft, the second pin shaft is arranged on the first transmission member, and the second pin shaft is rotatably connected with the first door panel; or,
[0027] The second pin shaft is arranged on the first door plate, and the second pin shaft is rotationally connected with the first transmission member; or,
[0028] One end of the second pin shaft is rotationally connected with the first transmission member, and the other end is rotationally connected with the first door plate. In this way, the first door plate and the first transmission member can be conveniently connected together through the second pin shaft.
[0029] In one of the embodiments, under the condition that the second pin shaft is arranged on the first transmission member, the second pin shaft is fixedly connected with the first transmission member. Since the second pin shaft is fixed on the first transmission member, in this way, it can be avoided that the second pin shaft and the first transmission member shake.
[0030] In one of the embodiments, under the condition that the second pin shaft is arranged on the first door plate, the second pin shaft is fixedly connected with the first door plate. Since the second pin shaft is fixed on the first transmission member, in this way, it can be avoided that the second pin shaft and the first transmission member shake.
[0031] In one of the embodiments, the first door plate is provided with a third shaft hole on the side facing the first swing arm, and the second pin shaft is rotationally connected with the first door plate through the third shaft hole at the end away from the first transmission member.
[0032] The second pin shaft is hindered from moving in any radial direction of the third shaft hole. In this way, the connection of the second pin shaft and the first door plate is facilitated. At the same time, since the second pin shaft is hindered from moving in any radial direction of the third shaft hole, that is, the second pin shaft cannot move in any radial direction relative to the third shaft hole, at this time, the second pin shaft will not shake relative to the third shaft hole, and the second pin shaft will only rotate relative to the third shaft hole under the limitation of the third shaft hole, thereby improving the transmission precision between the second pin shaft and the first door plate.
[0033] In one of the embodiments, the diameter of the second pin shaft is equal to the diameter of the third shaft hole. In this way, it can be effectively avoided that the second pin shaft shakes in the third shaft hole.
[0034] In one of the embodiments, the protruding part at one end of the first transmission member towards the first swing arm is in an arc shape, and the recessed part at one end of the first swing arm towards the first transmission member is in an arc shape, under the condition that the first swing arm drives the first door panel to be folded to a preset angle relative to the base through the first transmission member. In this way, no collision occurs between the first transmission member and the first swing arm when the first door panel is folded to the preset angle relative to the base. Moreover, since the protruding part at one end of the first transmission member towards the first swing arm is in an arc shape, and the recessed part at one end of the first swing arm towards the first transmission member is in an arc shape, the gap between the first transmission member and the first swing arm can be designed to be smaller.
[0035] In one of the embodiments, the rotating mechanism further comprises a first connecting block, which is arranged on the first door panel, and a boss is arranged on the first connecting block, and one end of the first transmission member is in a plane structure.
[0036] Under the condition that the first swing arm drives the first door panel to be folded to a preset angle relative to the base through the first transmission member, the boss is in abutment with the plane structure. In this way, when the boss is in abutment with the plane structure on the first transmission member, the first transmission member plays a counter-supporting role for the boss. Since the boss is arranged on the first connecting block, and the first connecting block is connected to the first door panel, the first transmission member plays a counter-supporting role for the first door panel, thereby avoiding the shaking phenomenon of the first door panel when being folded to the preset angle.
[0037] In one of the embodiments, the first direction is perpendicular to the rotation axis between the first swing arm and the first connecting member.
[0038] In one of the embodiments, the second direction is perpendicular to the rotation axis between the first connecting member and the first door panel.
[0039] In one of the embodiments, the rotating mechanism further comprises a second door panel, a second swing arm and a second connecting member.
[0040] One end of the second swing arm is rotationally connected to the base, the other end of the second swing arm is rotationally connected to one end of the second connecting member, and the other end of the second connecting member is rotationally connected to the second door panel.
[0041] In the process of rotating the second swing arm relative to the base, the second connecting member drives the second door panel to rotate relative to the base, and the second connecting member is hindered from moving in a third direction and a fourth direction, wherein the third direction intersects with a third rotation axis between the second swing arm and the second connecting member, and the fourth direction intersects with a fourth rotation axis between the second connecting member and the second door panel.
[0042] In the process of the second swing arm rotating relative to the base, the second connecting member can drive the second door panel to rotate relative to the base. In this process, since the second connecting member is hindered from moving in the third direction and the fourth direction, the third direction intersects the third rotation axis between the second swing arm and the second connecting member, and the fourth direction intersects the fourth rotation axis between the second connecting member and the second door panel, therefore, the second connecting member cannot move in the intersecting line direction of the third rotation axis, and at the same time, the second connecting member cannot move in the intersecting line direction of the fourth rotation axis. In this way, when the second connecting member rotates relative to the second swing arm, the second connecting member cannot move in the intersecting line direction of the third rotation axis on the second swing arm, at this time, only rotation exists between the second connecting member and the second swing arm, the second connecting member cannot sway relative to the second swing arm, and similarly, when the second connecting member rotates relative to the second door panel, the second connecting member cannot move in the intersecting line direction of the fourth rotation axis on the second door panel, at this time, only rotation exists between the second connecting member and the second door panel, the second connecting member cannot sway relative to the second door panel, thereby effectively improving the accuracy of the second door panel when rotating.
[0043] Secondly, the application provides an electronic device, which comprises the rotating mechanism as described in any one of the embodiments of the application.
[0044] It can be understood that the electronic device provided by the second aspect has the beneficial effects as described in the first aspect and any possible design manner, which will not be described herein. BRIEF DESCRIPTION OF DRAWINGS

[0062] The terms used in the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0063] The present application provides an electronic device, which is a kind of electronic device with a folding screen. Specifically, the electronic device 100 includes but is not limited to a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a personal computer, a notebook computer, a vehicle-mounted device, and a wearable device (such as a watch), and the like.
[0064] Please refer to FIG. 1, which is a perspective view of an electronic device 100 according to some embodiments of the present application. In the present embodiment, the electronic device 100 is a folding screen mobile phone. The electronic device 100 includes a folding screen 10 and a supporting device 20. It can be understood that FIG. 1 only schematically shows some components included in the electronic device 100, and the actual shape, actual size, actual position, and actual structure of these components are not limited by FIG. 1.
[0065] The folding screen 10 is used to display images, videos, etc. The folding screen 10 can be folded into a first part 11 and a second part 12. The folding screen 10 further comprises a third part 13 between the first part 11 and the second part 12. At least the third part 13 of the folding screen 10 is made of a flexible material. The first part 11 and the second part 12 can be made of a flexible material, can be made of a rigid material, or can be partially made of a rigid material and partially made of a flexible material, which is not limited here.
[0066] Specifically, the folding screen 10 can be an organic light-emitting diode (OLED) screen, a micro organic light-emitting diode (micro OLED) screen, a quantum dot light-emitting diode (QLED) screen, a liquid crystal display (LCD), etc.
[0067] The folding screen 10 can be folded between an unfolded state and a folded state.
[0068] Referring to FIG. 2, which is a structural schematic diagram of the electronic device 100 shown in FIG. 1 when the folding screen 10 is in the unfolded state. When the folding screen 10 is in the unfolded state, the first part 11, the second part 12, and the third part 13 are coplanarly arranged and face the same direction. In this state, large-screen display can be achieved, which can provide users with more abundant information and better user experience.
[0069] The support device 20 is used to support the folding screen 10 and allow the folding screen 10 to be folded between the unfolded state and the folded state. Referring to FIG. 3, which is a perspective view of the support device 20 in the electronic device 100 shown in FIG. 1. In this embodiment, the support device 20 comprises a first housing 21, a second housing 22, and a rotating mechanism 23. It can be understood that FIG. 3 only schematically shows some components included in the support device 20, and the actual shape, actual size, actual position, and actual structure of these components are not limited by FIG. 3.
[0070] The first housing 21 is used to fix and support the first part 11 of the folding screen 10 in FIG. 1, and the second housing 22 is used to fix and support the second part 12 of the folding screen 10 in FIG. 1. The inside of the first housing 21 forms a first accommodating cavity (not shown in the figure). The inside of the second housing 22 forms a second accommodating cavity (not shown in the figure). The first accommodating cavity and the second accommodating cavity are used to accommodate the main board, the battery, the camera module, the speaker, the earpiece, and other electronic devices of the electronic device 100.
[0071] The first shell 21 can be a structural whole or can be assembled by multiple parts. Similarly, the second shell 22 can be a structural whole or can be assembled by multiple parts.
[0072] The rotating mechanism 23 is used to support the third part 13 of the folding screen 10. The rotating mechanism 23 is connected between the first shell 21 and the second shell 22, and the first shell 21 and the second shell 22 are rotatably connected through the rotating mechanism 23.
[0073] The number of the rotating mechanism 23 can be one, two or more. The number can be determined according to actual conditions, which is not limited in the embodiments of the present application.
[0074] Referring to FIG. 4 and FIG. 5, the rotating mechanism 23 includes a base 231, a first door plate 232, a second door plate 233, a first swing arm 234, a second swing arm 235, a first connecting block 236, a second connecting block 237, a first pin shaft 238 and a second pin shaft 239. The first door plate 232 is provided with a first rotating part 2321, and the first rotating part 2321 is provided with a first sliding groove 23211. The second door plate 233 is provided with a second rotating part 2331, and the second rotating part 2331 is provided with a second sliding groove 23311. It can be understood that FIG. 5 only schematically shows some components of the rotating mechanism 23, and the actual shape, actual size, actual position and actual structure of these components are not limited by FIG. 5.
[0075] The one end of the first swing arm 234 is rotatably connected with the base 231, and the other end of the first swing arm 234 is connected with the first pin shaft 238. Meanwhile, the first pin shaft 238 is located in the first sliding groove 23211. The first connecting block 236 is bolted on the first door plate 232, and the first door plate 232 is connected with the first shell 21 through the first connecting block 236. When the first swing arm 234 rotates relative to the base 231, the first swing arm 234 can drive the first pin shaft 238 to move in the first sliding groove 23211, and then drive the first door plate 232 to rotate through the first rotating part 2321. The one end of the second swing arm 235 is rotatably connected with the base 231, and the other end of the second swing arm 235 is connected with the second pin shaft 239. Meanwhile, the second pin shaft 239 is located in the second sliding groove 23311. The second connecting block 237 is bolted on the second door plate 233, and the second door plate 233 is connected with the second shell 22 through the second connecting block 237. When the second swing arm 235 rotates relative to the base 231, the second swing arm 235 can drive the second pin shaft 239 to move in the second sliding groove 23311, and then drive the second door plate 233 to rotate through the second rotating part 2331.
[0076] Since the first rotating part 2321 is arranged on the first door plate 232, when the first door plate 232 rotates relative to the first swing arm 234, in order to avoid interference between the first rotating part 2321 and the first swing arm 234, as shown in FIG. 4, the gap H1 between the first door plate 232 and the first swing arm 234 is generally designed to be large. In this way, when the first door plate 232 rotates to 90° relative to the base 231, since the gap H1 between the first door plate 232 and the first swing arm 234 is large, at this time, the first door plate 232 and the first swing arm 234 do not contact each other, the first door plate 232 is not supported, and the first door plate 232 will shake relative to the first swing arm 234.
[0077] Referring to FIG. 5, generally, the distance a1 between the two inner walls in the first sliding groove 23211 is greater than the diameter of the first pin shaft 238, and the distance a2 between the two inner walls in the second sliding groove 23311 is greater than the diameter of the second pin shaft 239. In this way, the first pin shaft 238 will shake in the a1 direction between the two inner walls in the first sliding groove 23211, and the second pin shaft 239 will shake in the a2 direction between the two inner walls in the second sliding groove 23311. When the first swing arm 234 drives the first door plate 232 to rotate through the first pin shaft 238, since the first pin shaft 238 will shake in the first sliding groove 23211, the movement of the first door plate 232 cannot be accurately controlled through the first pin shaft 238. Similarly, the movement of the second door plate 233 cannot be accurately controlled through the second pin shaft 239.
[0078] In order to solve the above problems, as shown in FIG. 6 and in combination with FIG. 7, an embodiment of the present application provides a rotating mechanism 33, which comprises a base 331, a first door plate 332, a first swing arm 334 and a first connecting piece 336. One end of the first swing arm 334 is rotationally connected with the base 331, the other end of the first swing arm 334 is rotationally connected with one end of the first connecting piece 336, and the other end of the first connecting piece 336 is rotationally connected with the first door plate 332. In the process of rotating the first swing arm 334 relative to the base 331, the first connecting piece 336 drives the first door plate 332 to rotate relative to the base 331, and the first connecting piece 336 is hindered from moving in a first direction and a second direction. The first direction intersects with a first rotation axis between the first swing arm 334 and the first connecting piece 336, and the second direction intersects with a second rotation axis between the first connecting piece 336 and the first door plate 332.
[0079] Referring to FIGS. 7 and 8, the base 331 and the first door plate 332 in the embodiment are long strip structures. Of course, it can be understood that the base 331 and the first door plate 332 can also be square structures, and the specific structure can be determined according to actual conditions, and the embodiment of the present application does not limit this.
[0080] In the embodiment, as shown in FIG. 8, the base 331 is provided with an axle hole 3311, as shown in FIG. 9, the first swing arm 334 is also provided with an axle hole 3342, and the first swing arm 334 and the base 331 are rotationally connected through a pin shaft passing through the axle holes 3311 and 3342. The end of the first swing arm 334 away from the base 331 is rotationally connected with the first connecting piece 336. The embodiment is not limited to the connection structure of the first swing arm 334 and the base 331, and can be determined according to actual conditions.
[0081] In the embodiment, the first swing arm 334 is rotationally connected with the first connecting piece 336, and the first connecting piece 336 is rotationally connected with the first door plate 332. In use, in the process that the first swing arm 334 drives the first connecting piece 336 to rotate relative to the base 331, the first connecting piece 336 can drive the first door plate 332 to rotate relative to the base 331, so as to realize unfolding or folding of the first door plate 332 relative to the base 331.
[0082] The rotating mechanism 33 provided by the embodiment can drive the first connecting piece 336 to rotate relative to the base 331 in the process that the first swing arm 334 rotates relative to the base 331. In this process, since the first connecting piece 336 is hindered from moving in the first direction and the second direction, the first direction intersects with the first rotation axis between the first swing arm 334 and the first connecting piece 336, and the second direction intersects with the second rotation axis between the first connecting piece 336 and the first door plate 332, therefore, the first connecting piece 336 cannot move in the intersecting line direction of the first rotation axis, and at the same time, the first connecting piece 336 cannot move in the intersecting line direction of the second rotation axis. In this way, when the first connecting piece 336 rotates relative to the first swing arm 334, the first connecting piece 336 will not move in the intersecting line direction of the first rotation axis on the first swing arm 334.
[0083] Since any perpendicular line on the first rotation axis also intersects with the first rotation axis, at this time, the first connecting piece 336 will not move in the direction of any perpendicular line of the first rotation axis on the first swing arm 334, that is, the first connecting piece 336 will not shake relative to the first swing arm 334, and only rotation exists between the first connecting piece 336 and the first swing arm 334. Similarly, when the first connecting piece 336 rotates relative to the first door plate 332, the first connecting piece 336 will not move in the intersecting line direction of the second rotation axis on the first door plate 332, at this time, only rotation exists between the first connecting piece 336 and the first door plate 332, and the first connecting piece 336 will not shake relative to the first door plate 332, thereby effectively improving the accuracy of the first door plate 332 in rotation.
[0084] In some embodiments, as shown in FIG. 10, the first connecting member 336 comprises a first transmission member 3361, wherein, as shown in FIG. 11, one end of the first transmission member 3361 is rotationally connected to the end of the first swing arm 334 away from the base 331, and the other end of the first transmission member 3361 is rotationally connected to the side of the first door panel 332 facing the first swing arm 334; and the first transmission member 3361 is prevented from moving in the first direction and the second direction.
[0085] In the present embodiment, the first transmission member 3361 can be a connecting plate, a connecting rod or the like, which can be determined according to actual conditions, and the present specification embodiments are not limited in this regard.

[0098] In this embodiment, since the first swing arm 334 is provided with the first shaft hole 3341, the first pin shaft 3362 and the first swing arm 334 can be conveniently connected together.
[0099] Meanwhile, since the first pin shaft 3362 is hindered from moving in any radial direction along the first shaft hole 3341, that is, the first pin shaft 3362 cannot move in any radial direction relative to the first shaft hole 3341, at this time, the first pin shaft 3362 cannot shake relative to the first shaft hole 3341, and the first pin shaft 3362 can only rotate relative to the first shaft hole 3341 under the limitation of the first shaft hole 3341, thereby improving the transmission precision between the first swing arm 334 and the first pin shaft 3362.

[0101] In this embodiment, since the first transmission member 3361 is provided with the second shaft hole 33611, the first pin shaft 3362 can be conveniently connected with the first transmission member 3361.
[0102] Meanwhile, since the first pin shaft 3362 is hindered from moving in any radial direction along the second shaft hole 33611, that is, the first pin shaft 3362 cannot move in any radial direction relative to the second shaft hole 33611, at this time, the first pin shaft 3362 cannot shake relative to the second shaft hole 33611, and the first pin shaft 3362 can only rotate relative to the second shaft hole 33611 under the limitation of the second shaft hole 33611, thereby improving the transmission precision between the first pin shaft 3362 and the first transmission member 3361.
[0103] In some embodiments, the diameter of the one end of the first pin shaft 3362 is equal to the diameter of the first shaft hole 3341.
[0104] In this embodiment, when the one end of the first pin shaft 3362 is installed into the first shaft hole 3341, the first pin shaft 3362 can rotate relative to the first shaft hole 3341. Meanwhile, since the diameter of the one end of the first pin shaft 3362 is equal to the diameter of the first shaft hole 3341, the first pin shaft 3362 can be prevented from shaking in the first shaft hole 3341.
[0105] In some embodiments, the diameter of the other end of the first pin shaft 3362 is equal to the diameter of the second shaft hole 33611.
[0106] In this embodiment, when the one end of the first pin shaft 3362 is installed into the second shaft hole 33611, the first pin shaft 3362 can rotate relative to the second shaft hole 33611. Meanwhile, since the diameter of the one end of the first pin shaft 3362 is equal to the diameter of the second shaft hole 33611, the first pin shaft 3362 can be prevented from shaking in the second shaft hole 33611.
[0107] In some embodiments, as shown in FIG. 11 and in combination with FIG. 12, the first connecting piece 336 further comprises a second pin shaft 3363, wherein the second pin shaft 3363 is arranged on the first transmission member 3361 and rotationally connected with the first door plate 332, or the second pin shaft 3363 is arranged on the first door plate 332 and rotationally connected with the first transmission member 3361, or one end of the second pin shaft 3363 is rotationally connected with the first transmission member 3361 and the other end is rotationally connected with the first door plate 332.

[0109] The second pin shaft 3363 is arranged to conveniently connect the first transmission member 3361 and the first door plate 332.
[0110] In some embodiments, as shown in FIG. 11, when the second pin shaft 3363 is arranged on the first transmission member 3361, the second pin shaft 3363 is fixedly connected with the first transmission member 3361.
[0111] In this embodiment, the second pin shaft 3363 can be integrally formed with the first transmission member 3361 or welded, which can be determined according to actual conditions and is not limited in the embodiments of the present application.
[0112] Since one end of the second pin shaft 3363 is fixedly connected with the first transmission member 3361 and the other end is rotationally connected with the first door plate 332, when the first transmission member 3361 drives the first door plate 332 to rotate through the second pin shaft 3363, the second pin shaft 3363 and the first transmission member 3361 will not move relative to each other, so that the second pin shaft 3363 and the first transmission member 3361 will not shake, thereby improving the transmission precision between the second pin shaft 3363 and the first transmission member 3361.
[0113] In some embodiments, when the second pin shaft 3363 is arranged on the first door plate 332, the second pin shaft 3363 is fixedly connected with the first door plate 332.
[0114] In the embodiment, the second pin shaft 3363 can be integrally formed with, welded to, or the like, the first door plate 332, which can be determined according to actual conditions, and the embodiments of the present specification do not limit this.
[0115] Since one end of the second pin shaft 3363 is fixedly connected with the first door plate 332 and the other end is rotationally connected with the first transmission member 3361, when the first transmission member 3361 drives the first door plate 332 to rotate through the second pin shaft 3363, relative movement between the second pin shaft 3363 and the first door plate 332 does not occur, so that shaking between the second pin shaft 3363 and the first door plate 332 is avoided, and the transmission precision between the second pin shaft 3363 and the first door plate 332 is improved.
[0116] In some embodiments, as shown in FIG. 13, a third shaft hole 3321 is arranged on a side of the first door plate 332 facing the first swing arm 334, and an end of the second pin shaft 3363 away from the first transmission member 3361 is rotationally connected with the first door plate 332 through the third shaft hole 3321. The second pin shaft 3363 is prevented from moving in any radial direction of the third shaft hole 3321.
[0117] In the embodiment, since the third shaft hole 3321 is arranged on the first door plate 332, the second pin shaft 3363 can be conveniently connected with the first door plate 332.
[0118] At the same time, since the second pin shaft 3363 is prevented from moving in any radial direction of the third shaft hole 3321, that is, the second pin shaft 3363 cannot move in any radial direction relative to the third shaft hole 3321, at this time, the second pin shaft 3363 does not shake relative to the third shaft hole 3321, and the second pin shaft 3363 only rotates relative to the third shaft hole 3321 under the limitation of the third shaft hole 3321, so that the transmission precision between the second pin shaft 3363 and the first door plate 332 is improved.
[0119] In some embodiments, the diameter of the second pin shaft 3363 is equal to the diameter of the third shaft hole 3321.
[0120] In the embodiment, when one end of the second pin shaft 3363 is installed into the third shaft hole 3321, the second pin shaft 3363 can rotate relative to the third shaft hole 3321. At the same time, since the diameter of the one end of the second pin shaft 3363 is equal to the diameter of the third shaft hole 3321, shaking of the second pin shaft 3363 in the third shaft hole 3321 is avoided.
[0121] In some embodiments, as shown in FIG. 14 and in combination with FIG. 15, when the first swing arm 334 drives the first door panel 332 to fold to a preset angle relative to the base 331 through the first transmission member 3361, the protruding portion at one end of the first transmission member 3361 towards the first swing arm 334 is in an arc structure, and the recessed portion at one end of the first swing arm 334 towards the first transmission member 3361 is in an arc structure.
[0122] In the embodiment, when the first swing arm 334 drives the first door panel 332 to fold to 90° relative to the base 331 through the first transmission member 3361, the protruding portion at one end of the first transmission member 3361 towards the first swing arm 334 is in an arc structure, and the recessed portion at one end of the first swing arm 334 towards the first transmission member 3361 is in an arc structure.
[0123] At this time, no collision occurs between the first transmission member 3361 and the first swing arm 334. Moreover, since the protruding portion at one end of the first transmission member 3361 towards the first swing arm 334 is in an arc structure, and the recessed portion at one end of the first swing arm 334 towards the first transmission member 3361 is in an arc structure, the gap H2 between the first transmission member 3361 and the first swing arm 334 can be designed to be smaller, as long as no collision occurs between the first transmission member 3361 and the first swing arm 334 when rotating.
[0124] In the embodiment, since the gap between the first transmission member 3361 and the first swing arm 334 is small, when the first door panel 332 rotates to 90° relative to the base 331, the first connecting block 380 connected on the first door panel 332 together with the weight generated by the first door panel 332 can be transmitted to the first swing arm 334. Since the gap between the first swing arm 334 and the first transmission member 3361 on the first door panel 332 is small, the first swing arm 334 can play a role of counter-supporting the first transmission member 3361.
[0125] When the rotating mechanism 33 falls, at this time, since the first transmission member 3361 and the first swing arm 334 support each other, the first door panel 332 can be stably positioned on the first swing arm 334 through the first transmission member 3361, avoiding the first door panel 332 from shaking or colliding relative to the first swing arm 334. In this way, the folding screen connected on the first door panel 332 can also be prevented from shaking, thereby playing a role of protecting the folding screen.
[0126] In some embodiments, as shown in FIG. 14 and in combination with FIG. 16, the rotating mechanism further comprises a first connecting block 380 arranged on the first door plate 332, the first connecting block 380 is provided with a boss 3801, and one end of the first transmission member 3361 is in a planar structure; under the condition that the first swing arm 334 drives the first door plate 332 to be folded to a preset angle relative to the base 331 through the first transmission member 3361, the boss 3801 abuts against the planar structure.
[0127] In this embodiment, when the first swing arm 334 drives the first door plate 332 to be folded to 90° relative to the base 331 through the first transmission member 3361, the first connecting block 380 is provided with a boss 3801 at one end facing the first transmission member 3361, and the first transmission member 3361 is in a planar structure at one end facing the first connecting block 380.
[0128] At this time, the boss 3801 abuts against the planar structure 33612 on the first transmission member 3361, and the first transmission member 3361 plays a counter-supporting role for the boss 3801. Since the boss 3801 is located on the first connecting block 380, and the first connecting block 380 is connected to the first door plate 332, the first transmission member 3361 will play a counter-supporting role for the first door plate 332.
[0129] When the rotating mechanism 33 falls, at this time, since the first connecting block 380 and the first transmission member 3361 support each other, the first door plate 332 can be stably located on the first transmission member 3361 through the first connecting block 380, avoiding the first door plate 332 from shaking or colliding relative to the first transmission member 3361. In this way, the folding screen connected to the first door plate 332 can also be prevented from shaking, thereby playing a protective role for the folding screen.
[0130] In some embodiments, the first direction is perpendicular to the rotation axis between the first swing arm 334 and the first connecting member 336.
[0131] Referring to FIG. 11, in this embodiment, the first direction is any radial direction of the first pin shaft 3362.
[0132] In this embodiment, after the first swing arm 334 is connected to the first connecting member 336, that is, after the first swing arm 334 is connected to the first transmission member 3361 through the first pin shaft 3362, since the first transmission member 3361 is hindered from moving in the first direction, which is any radial direction of the first pin shaft 3362, when the first transmission member 3361 and the first pin shaft 3362 rotate, the first transmission member 3361 cannot move in any radial direction of the first pin shaft 3362. In this way, only rotation can exist between the first transmission member 3361 and the first pin shaft 3362, thereby improving the accuracy of the first swing arm 334 and the first transmission member 3361 when rotating.
[0133] In some embodiments, the second direction is perpendicular to the rotation axis between the first connecting member 336 and the first door plate 332.
[0134] Referring to FIG. 11, the second direction in the embodiment is any radial direction of the second pin shaft 3363.
[0135] In the embodiment, after the first connecting member 336 and the first door plate 332 are connected, i.e., after the first transmission member 3361 is connected to the first door plate 332 through the second pin shaft 3363, the first transmission member 3361 is prevented from moving in the second direction, which is any radial direction of the second pin shaft 3363, so that the first transmission member 3361 cannot move in any radial direction of the second pin shaft 3363 when the first transmission member 3361 and the second pin shaft 3363 rotate. In this way, only rotation can exist between the first transmission member 3361 and the second pin shaft 3363, thereby improving the accuracy of the rotation of the first transmission member 3361 and the first door plate 332.
[0136] In some embodiments, as shown in FIG. 11, the rotating mechanism further includes a second door plate 333, a second swing arm 335, and a second connecting member 337; one end of the second swing arm 335 is rotationally connected to the base 331, the other end of the second swing arm 335 is rotationally connected to one end of the second connecting member 337, and the other end of the second connecting member 337 is rotationally connected to the second door plate 333; in the process of rotation of the second swing arm 335 relative to the base 331, the second connecting member 337 drives the second door plate 333 to rotate relative to the base 331, and the second connecting member 337 is prevented from moving in a third direction and a fourth direction, wherein the third direction intersects a third rotation axis between the second swing arm 335 and the second connecting member 337, and the fourth direction intersects a fourth rotation axis between the second connecting member 337 and the second door plate 333.
[0137] The second connecting member 337 in the embodiment includes a second transmission member 3371, a third pin shaft 3372, and a fourth pin shaft 3373, wherein the second door plate 333 is provided with a shaft hole 3331, one end of the second swing arm 335 in the embodiment is rotationally connected to the base 331, the other end is rotationally connected to the second transmission member 3371 through the third pin shaft 3372, and the second transmission member 3371 is rotationally connected to the shaft hole 3331 on the second door plate 333 through the fourth pin shaft 3373. Meanwhile, the second door plate 333 is further connected with a second connecting block 390 through a bolt.
[0138] The connection structure of the base 331, the second swing arm 335, the third pin shaft 3372, the second transmission member 3371, the fourth pin shaft 3373, the shaft hole 3331 and the second door plate 333 in sequence is the same as the connection structure of the base 331, the first swing arm 334, the first pin shaft 3362, the first transmission member 3361, the second pin shaft 3363, the third shaft hole 3321 and the first door plate 332 in sequence, which will not be described here.
[0139] For the convenience of description, referring to FIG. 11, the third direction is defined as any radial direction of the third pin shaft 3372, and the fourth direction is defined as any radial direction of the fourth pin shaft 3373.
[0140] The rotating mechanism 33 provided in the embodiment of the present application can drive the second door plate 333 to rotate relative to the base 331 through the second transmission member 3371 during the rotation of the second swing arm 335 relative to the base 331. During this process, since the second connecting member 337 is hindered from moving along the first direction and the second direction, the first direction is any radial direction of the third pin shaft 3372, and the fourth direction is any radial direction of the fourth pin shaft 3373, the second transmission member 3371 cannot move along any radial direction of the third pin shaft 3372 when the second transmission member 3371 rotates with the third pin shaft 3372, so that only rotation exists between the second transmission member 3371 and the third pin shaft 3372, thereby improving the accuracy of the rotation of the second swing arm 335 and the second transmission member 3371.
[0141] Similarly, after the second transmission member 3371 is connected with the second door plate 333, that is, after the second transmission member 3371 is connected with the second door plate 333 through the fourth pin shaft 3373, since the second transmission member 3371 is hindered from moving along the fourth direction, the fourth direction is any radial direction of the fourth pin shaft 3373, the second transmission member 3371 cannot move along any radial direction of the fourth pin shaft 3373 when the second transmission member 3371 rotates with the fourth pin shaft 3373, so that only rotation exists between the second transmission member 3371 and the fourth pin shaft 3373, thereby improving the accuracy of the rotation of the second transmission member 3371 and the second door plate 333.
