DETAILED DESCRIPTION

[0038] The following are optional embodiments of the present application. It should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements are also considered within the scope of protection of the present application.

[0039] Please refer to Figure 1 and Figure 2 , Figure 1 The structural schematic diagram of the display device provided for an embodiment. Figure 2 The structural schematic diagram of the support device and the to-be-supported piece provided for another embodiment of the present application.

[0040] The present embodiment provides a support device 10 for supporting a to-be-supported piece 20, wherein the to-be-supported piece 20 has a connecting surface 20a. The support device 10 comprises a base 100 and a support assembly 200, wherein the support assembly comprises a first support 210 and a second support 220, one end of the first support 210 is connected to the base 100, the other end of the first support 210 is connected to one end of the second support 220, and the other end of the second support 220 is used for connecting the connecting surface of the to-be-supported piece 20; wherein the other end of the first support 210 is rotationally connected to one end of the second support 220, or the other end of the second support 220 is used for rotationally connecting the to-be-supported piece 20, so that the rotating direction of the to-be-supported piece 20 is parallel to the connecting surface 20a; and the to-be-supported piece 20 can also move in the direction of approaching or moving away from the base 100; wherein when the to-be-supported piece 20 rotates relative to the base 100, the to-be-supported piece 20 can also move synchronously relative to the base 100.

[0041] Furthermore, the terms "comprise", "comprising", "have", "having", "include", "including", "contain", "containing", "provide", "providing", "offer", "offering", "specify", "specifying", "create", "creating", "form", "forming", "use", "using", "make", "making" and any variations thereof in the description and in the claims are intended to cover a non-exclusive inclusion.

[0042] The support device 10 provided by the embodiment includes a base 100, which is used to connect the support assembly 200. The base 100 has a bottom surface 100a, which is used to be placed on any plane. The base 100 improves the assembly stability of the support assembly 200. The shape, material and thickness of the base 100 are not limited in the present application.

[0043] The support device 10 provided by the embodiment includes a support assembly 200, which is used to connect the base 100 and the to-be-supported member 20. The connection mode of one end of the support assembly 200 to the base 100 includes but is not limited to rotary connection, sliding connection, fixed connection and the like. Alternatively, when the connection mode of one end of the support assembly 200 to the base 100 is rotary connection, the rotary direction of the support assembly 200 relative to the base 100 can be different. Specifically, the support assembly 200 can be rotated relative to the bottom surface 100a to change the angle between the support assembly 200 and the bottom surface 100a, or the support assembly 200 can be rotated along the axial direction of itself. The shape, material and thickness of the support assembly 200 are not limited in the present application.

[0044] The other end of the support assembly 200 is connected to the side of the to-be-supported member 20 opposite to the connection surface 20a. The connection mode of the to-be-supported member 20 to the other end of the support assembly 200 includes but is not limited to rotary connection, sliding connection, fixed connection and the like. Alternatively, when the connection mode of the to-be-supported member 20 to the other end of the support assembly 200 is rotary connection, the to-be-supported member 20 can be rotated along the direction parallel to the connection surface 20a (for example, as shown by the direction D2 in the figure), or the to-be-supported member 20 can be rotated relative to the support assembly 200 to change the angle between the to-be-supported member 20 and the support assembly 200. Figure 1

[0045] In other words, the to-be-supported member 20 can be rotated along the direction parallel to the connection surface 20a in clockwise or counterclockwise direction to realize the conversion between landscape mode and portrait mode or the conversion between portrait mode and landscape mode. In the embodiment, the to-be-supported member is rotated along the direction close to or away from the base (for example, as shown by the direction D1 in the figure) to realize the conversion between landscape mode and portrait mode or the conversion between portrait mode and landscape mode. Figure 1 ​The second support 220 can rotate along its axial direction, thereby driving the to-be-supported member 20 to rotate along the axial direction of the second support 220, and the second support 220 can also be synchronously raised or lowered relative to the base 100 and the first support 210. When the other end of the second support 220 is rotationally connected to the connecting surface 20a of the to-be-supported member 20, the to-be-supported member 20 can rotate along a direction parallel to the connecting surface 20a, and the second support 220 can also be synchronously raised or lowered relative to the base 100 and the first support 210. In this case, the second support 220 will not rotate along its axial direction. The to-be-supported member 20 includes but is not limited to a display screen, and when the to-be-supported member 20 is a display screen, the display screen has a display surface 20b. The display screen can be a liquid crystal display screen or an organic electroluminescent display screen, a television screen (TV), a computer screen (MNT), etc., which provides functions such as text reading, video interaction, and screen projection for users. The shape, material, and thickness of the to-be-supported member 20 are not limited in this embodiment.

[0046] In an embodiment, one end of the support assembly 200 is rotationally connected to the base 100, and the support assembly 200 can rotate around its axial direction. Since the other end of the support assembly 200 is connected to the to-be-supported member 20, rotation of the support assembly 200 can drive the to-be-supported member 20 to rotate synchronously. The connection relationship between the other end of the support assembly 200 and the to-be-supported member 20 is not limited in this embodiment.

[0047] In another embodiment, the to-be-supported member 20 can also rotate along a direction parallel to the connecting surface 20a. In other words, one end of the support assembly 200 away from the base 100 is at the connecting position of the to-be-supported member 20, and the to-be-supported member 20 rotates around the connecting position as the center. The connection relationship between the support assembly 200 and the base 100 is not limited in this embodiment.

[0048] In another embodiment, the support assembly 200 can also synchronously raise the to-be-supported piece 20 when the to-be-supported piece 20 switches from the horizontal screen state to the vertical screen state; the support assembly 200 can also synchronously lower the to-be-supported piece 20 when the to-be-supported piece 20 switches from the horizontal screen state to the vertical screen state. Of course, in other embodiments, the support assembly 200 can also synchronously raise the to-be-supported piece 20 when the to-be-supported piece 20 switches from the vertical screen state to the horizontal screen state; the support assembly 200 can also synchronously lower the to-be-supported piece 20 when the to-be-supported piece 20 switches from the vertical screen state to the horizontal screen state, which should all belong to the protection scope of the present embodiment.

[0049] Based on the fact that most of the TV screens and computer screens on the market are in the horizontal screen state, the screen length-width ratio is usually 4:3 or 16:9, and most of the mobile devices used by users are in the vertical screen state, the switching between the horizontal screen and the vertical screen is not convenient and smooth when the mobile device is projected to the display screen.

[0050] The present application provides the specific structures of two support assemblies. Please refer to Figure 2 , Figure 2 The structure diagram of the support device and the to-be-supported piece provided by another embodiment of the present application.

[0051] In the first structure, the support assembly 200 provided by the present embodiment includes a first support piece 210, which is used to connect the base 100 and the to-be-supported piece 20. The present application does not limit the shape, material and thickness of the first support piece 210.

[0052] In an embodiment, one end of the first support piece 210 is rotationally connected to the base 100, and the other end of the support piece is used to connect the to-be-supported piece 20. Wherein, the end of the first support piece 210 close to the base 100 can control the rotation of the first support piece 210 relative to the base 100. For example, the first support piece 210 can rotate relative to the bottom surface 100a to change the angle between the first support piece 210 and the bottom surface 100a, or the first support assembly 200 can rotate along the axial direction of itself. The end of the first support piece 210 away from the base 100 is connected to the side of the to-be-supported piece 20 away from the connecting surface 20a. Wherein, the connection mode between the first support piece 210 and the to-be-supported piece 20 includes but is not limited to rotational connection, sliding connection, fixed connection and the like. The present embodiment does not make specific limitation.

[0053] In another embodiment, one end of the first support 210 is connected to the base 100, and the other end is used for rotationally connecting the to-be-supported member 20. The connection between the end of the first support 210 close to the base 100 and the base 100 includes, but is not limited to, rotationally connecting, slidingly connecting, fixedly connecting, and the like. The present embodiment is not specifically limited. The end of the first support 210 away from the base 100 is rotationally connected to the to-be-supported member 20. The to-be-supported member 20 can rotate relative to the bottom surface 100a to change the angle between the first support 210 and the to-be-supported member 20, or the to-be-supported member 20 can rotate along a direction parallel to the connecting surface 20a.

[0054] The present embodiment can achieve connection by setting a conventional connection mode at both ends of the first support 210, and can also be rotationally connected, so that the to-be-supported member 20 can move in various angular postures in space, improve the flexibility of the support device 10, meet the use function of the product in various situations of the user, and improve the use experience of the user.

[0055] In the second structure, please refer to Figure 3 , Figure 3 The support device and the structure of the to-be-supported member provided in the embodiment of the present application are shown in the structural schematic diagram.

[0056] The support assembly 200 provided in the present embodiment includes a first support 210 and a second support 220. One end of the first support 210 is connected to the base 100, the other end of the first support 210 is connected to one end of the second support 220, and the other end of the second support 220 is used for connecting the to-be-supported member 20. The present application does not limit the shape, material, and thickness of the first support 210 and the second support 220.

[0057] The connection between the end of the first support 210 close to the base 100 and the base 100 includes, but is not limited to, rotationally connecting, slidingly connecting, fixedly connecting, and the like. Alternatively, when the first support 210 is rotationally connected to the base 100, the first support 210 can rotate around a direction parallel to the bottom surface 100a, or the first support 210 can rotate along the axial direction of itself. The end of the first support 210 close to the base 100 can adjust the rotation of the first support 210 relative to the base 100.

[0058] The end of the second support 220 is connected to the end of the first support 210 away from the base 100. The connection mode includes but is not limited to rotation connection, sliding connection, fixed connection, etc. Alternatively, when the second support 220 is rotationally connected to the first support 210, the second support 220 can rotate around the direction parallel to the bottom surface 100a at the end of the first support 210 away from the base 100, or the second support 220 can rotate along the axial direction of itself. To achieve that the second support 220 can rotate relative to the first support 210.

[0059] Specifically, the end of the second support 220 away from the first support 210 is connected to the side of the to-be-supported part 20 away from the connecting surface 20a. The connection mode of the to-be-supported part 20 to the second support 220 includes but is not limited to rotation connection, sliding connection, fixed connection, etc. Alternatively, the to-be-supported part 20 is rotationally connected to the second support 220, and the to-be-supported part 20 can rotate along the direction parallel to the connecting surface 20a, or the to-be-supported part 20 can rotate around the direction parallel to the bottom surface 100a.

[0060] The first support 210 can swing relative to the base 100, the second support 220 can swing relative to the first support 210, and the to-be-supported part 20 can rotate relative to the second support 220, so that the support device 10 can adjust the to-be-supported part 20 in multiple angles and postures.

[0061] Please continue to refer to Figure 3 , Figure 3 The structure diagram of the support device and the to-be-supported part provided by an embodiment of the present application.

[0062] The other end of the second support 220 is used to rotationally connect the to-be-supported part 20. Specifically, the end of the second support 220 away from the first support 210 is rotationally connected to the to-be-supported part 20. It can be understood that when the second support 220 is rotationally connected to the to-be-supported part 20, the to-be-supported part 20 can rotate along the direction parallel to the connecting surface 20a, so that the to-be-supported part 20 can switch between the horizontal screen state and the vertical screen state. The connection mode of the first support 210 and the second support 220 includes but is not limited to rotation connection, sliding connection, fixed connection, etc. The embodiment is not limited in particular.

[0063] Another embodiment provides that the other end of the first support 210 is rotationally connected to one end of the second support 220. Specifically, the end of the first support 210 away from the base 100 is rotationally connected to the end of the second support 220 away from the to-be-supported member 20. Understandably, when the first support 210 is rotationally connected to the second support 220, the second support 220 can rotate along the axial direction of itself. The connection mode of the second support 220 to the to-be-supported member 20 includes, but is not limited to, rotational connection, sliding connection, fixed connection, etc. The present embodiment is not limited in particular. The to-be-supported member 20 can be switched between the horizontal screen state and the vertical screen state.

[0064] Further, the end of the second support 220 away from the first support 210 can be rotationally connected to any region of the to-be-supported member 20 away from the connection surface 20a. Alternatively, the end of the second support 220 away from the first support 210 can be connected to the central region of the to-be-supported member 20 away from the connection surface 20a, so that the to-be-supported member 20 is uniformly stressed when supported on the support assembly 200, facilitating the adjustment of the support assembly 200 to rotate the to-be-supported member 20 and improving the assembly stability of the to-be-supported member 20 and the support assembly 200.

[0065] The support device 10 provided by the present embodiment realizes the support of the to-be-supported member 20 by connecting the connection surface 20a of the to-be-supported member 20 to the other end of the second support 220. The to-be-supported member 20 can also rotate relative to the base 100, and the rotation direction of the to-be-supported member 20 is parallel to the connection surface 20a, thereby realizing the conversion between the horizontal screen and the vertical screen. The to-be-supported member 20 can also move relative to the base 100, i.e., move in the direction of approaching or moving away from the base 100, thereby realizing the lifting and lowering of the to-be-supported member 20.

[0066] In addition, the present application can make the to-be-supported member 20 move relative to the base 100 when the to-be-supported member 20 rotates relative to the base 100. In other words, when the to-be-supported member 20 is converted between the horizontal screen and the vertical screen, the to-be-supported member 20 can be simultaneously lifted and lowered, thereby reducing the operation difficulty of the support device and making the operation simpler.

[0067] Please refer to Figures 4-6 , Figure 4 The structural schematic diagram of the support device and the to-be-supported member provided by another embodiment of the present application. Figure 5 The structural schematic diagram of the support device and the to-be-supported member provided by another embodiment of the present application. Figure 6 The connection schematic diagram of the first rotating member, the second rotating member, and the rack provided by an embodiment of the present application.

[0068] In one embodiment, when the other end of the first support 210 is rotationally connected to one end of the second support 220, the support device 10 further comprises a first rotating member 310, a second rotating member 320, and a rack 330 arranged in the first support 210, the extending direction of the rack 330 being parallel to the axial direction of the first support 210; the first rotating member 310 is fixedly connected to one end of the second support 220, the first rotating member 310 is rotationally connected to the second rotating member 320, and the second rotating member 320 is rotationally connected to the rack 330.

[0069] The side of the first support 210 away from the base 100 is provided with a sliding groove 211, the extending direction of the sliding groove 211 being parallel to the axial direction of the first support 210. The first rotating member 310, the second rotating member 320, and the rack 330 are arranged in the sliding groove 211. The sliding groove 211 has a first side surface 211a and a second side surface 211b arranged oppositely, and a third side surface 211c connecting the first side surface 211a and the second side surface 211b.

[0070] The first rotating member 310 provided by the embodiment comprises a first gear 311 and a first connecting shaft 312, the first gear 311 is sleeved on one end of the first connecting shaft 312, and the end of the connecting shaft away from the first gear 311 is connected to the end of the second support 220 away from the support-to-be-supported 20. For example, when the second support 220 rotates, the second support 220 drives the first connecting shaft 312 to rotate, and the rotation of the first connecting shaft 312 drives the first gear 311 to rotate. The rotating direction of the first rotating member 310 is parallel to the third side surface 211c, and the first rotating member 310 has a spacing with the third side surface 211c. The rotating direction of the first rotating member 310 is consistent with the rotating direction of the second support 220. The first rotating member 310 can rotate clockwise or counterclockwise. The shape, material, and thickness of the first gear 311 and the first connecting shaft 312 are not limited in the embodiment. The connection mode of the connecting shaft and the second support 220 includes but is not limited to clamping, bonding, and the like. The embodiment is not specifically limited.

[0071] The second rotating member 320 provided by the embodiment includes a second gear 325 and a second connecting shaft 323, and the first gear 311 is sleeved on the first connecting shaft 312. The side of the second gear 325 away from the first side surface 211a is in gear transmission with the first gear 311. For example, when the first transmission member rotates, the first connecting shaft 312 rotates to drive the first gear 311 to rotate, and the first gear 311 drives the second gear 325 to rotate. The rotating direction of the second rotating member 320 is parallel to the third side surface 211c, and the second rotating member 320 has a spacing with the third side surface 211c. The second rotating member 320 can rotate clockwise or counterclockwise. The rotating direction of the second rotating member 320 is opposite to the rotating direction of the first rotating member 310. For example, when the first rotating member 310 rotates clockwise, the second rotating member 320 rotates counterclockwise. The shape, material and thickness of the second gear 325 and the second connecting shaft 323 are not limited in the embodiment.

[0072] The rack 330 provided by the embodiment can be arranged on the first side surface 211a or the second side surface 211b of the first support member 210, which is not limited in the embodiment. The rack 330 is in gear transmission with the second gear 325. The second gear 325 can move along the extending direction of the rack 330. The rack 330 also has a starting end 331 and an ending end 332. Alternatively, the end of the rack 330 close to the base 100 is the starting end 331, and the end of the rack 330 away from the base 100 is the ending end 332. The first rotating member 310 and the second rotating member 320 can move between the starting end 331 and the ending end. When the to-be-supported member 20 is in the horizontal screen state, the first rotating member 310 and the second rotating member 320 are located at the starting end 331; when the to-be-supported member 20 is in the vertical screen state, the first rotating member 310 and the second rotating member 320 are located at the ending end 332. The shape, material and thickness of the rack 330 are not limited in the embodiment.

[0073] In the embodiment, when the to-be-supported member 20 rotates, the second support member 220, the first rotating member 310 and the second rotating member 320 are sequentially driven to rotate, and in turn drive the to-be-supported member 20 to move synchronously along the axial direction of the first support member 210.

[0074] It can be understood that when the to-be-supported part 20 is switched from the horizontal screen state to the vertical screen state, the connecting surface 20a of the to-be-supported part 20 rotates along the clockwise direction parallel to the connecting surface 20a, and the second supporting part 220 synchronously rotates in the clockwise direction along with the rotating direction of the to-be-supported part 20. At the same time, the second supporting part 220 drives the first rotating part 310 to rotate in the clockwise direction, and since the first rotating part 310 and the second rotating part 320 are in meshing transmission, the second transmission part rotates in the counterclockwise direction, and finally the second transmission part can move on the rack 330 from the starting end 331 to the direction of the terminal end 332, that is, moves upwards as shown in Figure 4

[0075] Conversely, when the to-be-supported part 20 is switched from the vertical screen state to the horizontal screen state, the connecting surface 20a of the to-be-supported part 20 rotates along the counterclockwise direction parallel to the connecting surface 20a, and the second supporting part 220 synchronously rotates in the counterclockwise direction along with the rotating direction of the to-be-supported part 20. At the same time, the second supporting part 220 drives the first rotating part 310 to rotate in the counterclockwise direction, and since the first rotating part 310 and the second rotating part 320 are in meshing transmission, the second transmission part rotates in the clockwise direction, and finally the second transmission part can move on the rack 330 from the terminal end 332 to the direction of the starting end 331, that is, moves downwards as shown in Figure 5

[0076] The supporting device 10 provided by the embodiment realizes that the first rotating part 310 can synchronously rotate along with the rotation of the to-be-supported part 20 by arranging the first rotating part 310, the second rotating part 320 and the rack 330 on the first supporting part 210, and rotatingly connecting the second supporting part 220 and the first rotating part 310. Considering that when the to-be-supported part 20 is switched from the horizontal screen state to the vertical screen state, the distance between the to-be-supported part 20 and the base 100 will be reduced, in order to prevent the to-be-supported part 20 from colliding with the base 100, the embodiment opens the sliding groove 211 in the first supporting part 210, and arranges the rack 330 in the sliding groove 211, and further adds the second rotating part 320 matched with the rack 330 and the linkage relationship between the second rotating part 320 and the first rotating part 310, so that when the to-be-supported part 20 is switched from the horizontal screen state to the vertical screen state, the to-be-supported part 20 can move away from the base 100, thereby avoiding the collision between the to-be-supported part 20 and the base 100, improving the safety factor of the to-be-supported part 20 and the base 100, and enhancing the user experience.

[0077] Please refer to​​Figure 4 、 Figure 5 、 Figure 7 , Figure 4 Structure diagram of the support device and the to-be-supported member according to another embodiment of the present application. Figure 5 Structure diagram of the support device and the to-be-supported member according to another embodiment of the present application. Figure 7 Connection diagram of the first rotating member, the second rotating member and the rack according to another embodiment of the present application.

[0078] The second rotating member 320 provided by the embodiment comprises the second gear 325, which comprises a first sub-gear 321 and a second sub-gear 322 arranged coaxially, and a second connecting shaft 323 connected to the first sub-gear 321 and the second sub-gear 322, wherein the first sub-gear 321 is rotationally connected to the first gear 311, and the second sub-gear 322 is rotationally connected to the rack 330.

[0079] The first sub-gear 321 and the second sub-gear 322 are arranged at two ends of the second connecting shaft 323 respectively, and the first sub-gear 321 and the second sub-gear 322 rotate coaxially. The first sub-gear 321 is rotationally connected to the first gear 311, and the second sub-gear 322 is rotationally connected to the rack 330. The first gear 311 is in meshing transmission with the first sub-gear 321 and the second sub-gear 322 is in meshing transmission with the rack 330.

[0080] It can be understood that when the to-be-supported part 20 is switched from the horizontal screen state to the vertical screen state, the connecting surface 20a of the to-be-supported part 20 rotates along the clockwise direction parallel to the connecting surface 20a, and the second supporting part 220 rotates synchronously in the clockwise direction along with the rotating direction of the to-be-supported part 20. Meanwhile, the second supporting part 220 drives the first rotating part 310 to rotate in the clockwise direction, the first gear 311 is in meshing transmission with the first sub-gear 321, when the first gear 311 rotates in the clockwise direction, the first sub-gear 321 rotates in the counterclockwise direction, since the first sub-gear 321 and the second sub-gear 322 are coaxially arranged, the second sub-gear 322 also rotates in the counterclockwise direction, the second sub-gear 322 is in meshing transmission with the rack 330, thus the second sub-gear 322 moves on the rack 330 from the direction close to the starting end 331 to the direction of the terminal end 332. The second sub-gear 322 drives the first sub-gear 321 and the second connecting shaft 323 to synchronously move in the direction of the terminal end 332. The first sub-gear 321 drives the first gear 311 to move in the direction of the terminal end 332, the first sub-gear 321 drives the second supporting part 220 and the to-be-supported part 20 to move in the direction of the terminal end 332. So as to prevent the to-be-supported part 20 from colliding with the base 100 when switched from the horizontal screen state to the vertical screen state. Conversely, when the to-be-supported part 20 is switched from the vertical screen state to the horizontal screen state, the corresponding transmission principle is the same, which will not be described herein.

[0081] In an embodiment, during the process of switching from the horizontal screen to the vertical screen, the to-be-supported part 20 will move upward, but in order to further avoid the to-be-supported part 20 from interfering with the base 100 or other components, the moving value of the second sub-gear 322 on the rack 330 should be greater than the minimum spacing value between the to-be-supported part 20 and the base 100. For example, when the number of teeth of the first gear 311 is 1-10 times the number of teeth of the first sub-gear 321, the above requirement can be met. Alternatively, the number of teeth of the first sub-gear 321 can be 14-25, and the number of teeth of the first gear 311 is 14-100. Specifically, when the number of teeth of the first gear 311 is 4 times the number of teeth of the first sub-gear 321, when the to-be-supported part 20 rotates 90 degrees, the first gear 311 synchronously rotates 90 degrees, and the first sub-gear 321 and the second sub-gear 322 rotate 360 degrees, the second sub-gear 322 rotates a circle relative to the rack 330, that is, the moving value of the second sub-gear 322 on the rack 330 is 2 times the diameter of itself. It can be understood that the moving value of the second sub-gear 322 on the rack 330 is at least the spacing value between the to-be-supported part 20 and the base 100.

[0082] The first gear 311 has a number of teeth in the range of 1-10 times the number of teeth of the first sub-gear 321, so that the support-to-be-supported 20 can avoid collision with the base 100 when rotating, thereby improving the safety of the support device 10.

[0083] Please refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 , Figure 3 The structure schematic diagram of the support device and the support-to-be-supported provided by an embodiment of the present application.

Figure 8 The structure schematic diagram of the rotating sleeve and the rotating shaft provided by an embodiment of the present application. Figure 9 The cross-sectional view of the rotating sleeve and the rotating shaft provided by an embodiment of the present application.

[0084] In the embodiment, one end of the first support 210 and the base 100, or the other end of the first support 210 and the support-to-be-supported 20, or the other end of the first support 210 and one end of the second support 220, or the other end of the second support 220 and the support-to-be-supported 20 can be rotationally connected by the rotating shaft 410 and the rotating sleeve 420, and the rotating sleeve 420 is sleeved on the rotating shaft 410.

[0085] In an embodiment, one end of the second support 220 away from the first support 210 and the support-to-be-supported 20 are rotationally connected by the rotating shaft 410 and the rotating sleeve 420.

[0086] Optionally, the rotating shaft 410 is arranged at one end of the second support 220 away from the first support 210, and the connection mode of the rotating shaft 410 and the second support 220 includes but is not limited to clamping, bonding, etc., or the rotating shaft 410 is integrally formed with the second support 220. The shape, material and thickness of the rotating shaft 410 are not limited in the embodiment.

[0087] Further, the rotating sleeve 420 is arranged on a side of the to-be-supported member 20 away from the connecting surface 20a, and the rotating sleeve 420 can be protruded from the to-be-supported member 20. The connecting manner between the rotating sleeve 420 and the to-be-supported member 20 includes but is not limited to clamping, bonding and the like, or the rotating shaft 410 and the second supporting member 220 are integrally formed. Of course, in other embodiments, the rotating sleeve 420 can also be recessed in the to-be-supported member 20. The shape, material and thickness of the rotating sleeve 420 are not limited in the embodiment.

[0088] Optionally, the rotating shaft 410 can also be arranged on a side of the to-be-supported member 20 away from the connecting surface 20a, and the rotating shaft 410 is protruded from the to-be-supported member 20. The connecting manner between the rotating shaft 410 and the to-be-supported member 20 includes but is not limited to clamping, bonding and the like, or the rotating shaft 410 and the second supporting member 220 are integrally formed. The shape, material and thickness of the rotating shaft 410 are not limited in the embodiment.

[0089] Further, the rotating sleeve 420 is arranged on a side of the to-be-supported member 20 away from the connecting surface 20a, and the rotating sleeve 420 can be protruded from the to-be-supported member 20. The connecting manner between the rotating sleeve 420 and the to-be-supported member 20 includes but is not limited to clamping, bonding and the like, or the rotating shaft 410 and the second supporting member 220 are integrally formed. Of course, in other embodiments, the rotating sleeve 420 can also be recessed in the to-be-supported member 20. The shape, material and thickness of the rotating sleeve 420 are not limited in the embodiment.

[0090] The rotating shaft 410 and the rotating sleeve 420 are rotatably connected, so that the to-be-supported member 20 can rotate relative to the second supporting member 220, to achieve that the to-be-supported member 20 can be switched between the horizontal screen state and the vertical screen state, and improve user experience.

[0091] Of course, in other embodiments, for example, one end of the first supporting member 210 and the base 100, or the other end of the first supporting member 210 and the to-be-supported member 20, or the other end of the first supporting member 210 and one end of the second supporting member 220 can be rotatably connected through the rotating shaft 410 and the rotating sleeve 420. The specific connecting manner and arrangement manner are consistent with the above description, and will not be described here.

[0092] Further optionally, the outer circumferential side of the rotating shaft 410 includes a plurality of first sub-surfaces 410a connected by bending. The inner circumferential side of the rotating sleeve 420 includes a plurality of second sub-surfaces 420a connected by bending and corresponding to the plurality of first sub-surfaces 410a.

[0093] The outer circumferential surface of the rotating shaft 410 is provided with a plurality of first sub-surfaces 410a connected in sequence by bending. The radial section of the rotating shaft 410 is in a polygonal shape. Optionally, the radial section of the rotating shaft 410 can be in a regular polygonal shape, which has higher stability due to the equal length of each side of the regular polygon. The inner circumferential surface of the rotating sleeve 420 is provided with a plurality of second sub-surfaces 420a connected in sequence by bending. The radial section of the rotating sleeve 420 is in a polygonal shape. Optionally, the radial section of the rotating sleeve 420 can be in a regular polygonal shape, which has higher stability due to the equal length of each side of the regular polygon.

[0094] When the rotating shaft 410 is sleeved on the rotating sleeve 420, the first sub-surfaces 410a correspond to and abut against the second sub-surfaces 420a. When the rotating shaft 410 rotates relative to the rotating sleeve 420, the first sub-surfaces 410a will rotate in sequence to the adjacent first sub-surfaces 410a and abut against the adjacent second sub-surfaces 420a. Since the rotating shaft 410 and the rotating sleeve 420 are both in a polygonal structure, when the rotating shaft 410 rotates, the rotating sleeve 420 is supported by the edges of the rotating shaft 410 and will be deformed radially. When the first sub-surfaces 410a abut against the adjacent second sub-surfaces 420a, the rotating sleeve 420 will return to the normal state. Since the radial sections of the rotating shaft 410 and the rotating sleeve 420 are both in a regular polygonal shape, the rotating shaft 410 is limited to rotate in the sleeve 540 without external force, realizing the function of limiting rotation.

[0095] In the embodiment, the plurality of first sub-surfaces 410a are arranged on the outer circumferential surface of the rotating shaft 410 and the plurality of second sub-surfaces 420a are arranged on the inner circumferential surface of the rotating sleeve 420, so that the rotating shaft 410 and the rotating sleeve 420 both have the functions of rotation and limiting. The mechanical mobility of the rotating shaft 410 and the rotating sleeve 420 is further improved.

[0096] Please refer to Figures 1-3 , Figure 1 The structure schematic diagram of the support device and the supported member provided in an embodiment of the present application. Figure 2 The structure schematic diagram of the support device and the supported member provided in another embodiment of the present application. Figure 3 The structure schematic diagram of the support device and the supported member provided in an embodiment of the present application.

[0097] The first support 210 can be rotatably connected to the base 100, the second support 220, and the object to be supported 20 by a rotating structure, so as to change the angle between the first support 210, the second support 220, the object to be supported 20, and the base 100.

[0098] In one embodiment, when the support assembly 200 only includes the first support 210, either end of the first support 210 can be provided with the rotating structure. For example, if the rotating structure is provided at the connection between the first support 210 and the base 100, the rotating shaft 410 and the rotating sleeve 420 are provided at the connection between the end of the first support 210 away from the base 100 and the object to be supported 20; or if the rotating structure is provided at the connection between the end of the first support 210 away from the base 100 and the object to be supported 20, the rotating shaft 410 and the rotating sleeve 420 are provided at the connection between the first support 210 and the base 100.

[0099] In another embodiment, when the support assembly 200 includes the first support 210 and the second support 220, and the support assembly 200 is provided with only one rotating structure, the rotating structure can be provided at the connection between the base 100 and the first support 210, the connection between the first support 210 and the second support 220, or the connection between the second support 220 and the object to be supported 20.

[0100] In other embodiments, when the support assembly 200 includes the first support 210 and the second support 220, and the support assembly 200 is provided with only two rotating structures, the rotating structures can be provided at the connection between the base 100 and the first support 210 and the connection between the first support 210 and the second support 220, or the connection between the base 100 and the first support 210 and the connection between the second support 220 and the object to be supported 20.

[0101] When the connection between the first support 210 and the second support 220 is provided with the rotating structure, the rotating shaft 410 and the rotating sleeve 420 are provided at the connection between the second support 220 and the object to be supported 20, so that the object to be supported 20 can rotate in a direction parallel to the connection surface 20a.

[0102] When the second support 220 is provided with a rotating structure at the connection with the support-to-be-supported 20, the rotating shaft 410 and the rotating sleeve 420 are arranged at the connection between the first support 210 and the second support 220, so that the second support 220 can rotate along its own axis, thereby driving the support-to-be-supported 20 to rotate in a direction parallel to the connecting surface 20a.

[0103] The embodiment changes the angle and posture of the support-to-be-supported 20 relative to the base 100 by arranging at least one rotating structure at any joint connection of the support device 10. The rotating structure can be arranged individually or in pairs, thereby enhancing the functionality of the product and increasing the options for users.

[0104] Please refer to Figure 10 、 Figure 11 , Figure 10 for Figure 5 the cross-sectional view along the line A-A in FIG. 1. Figure 11 for Figure 5 another cross-sectional view along the line A-A in FIG. 1.

[0105] The rotating structure provided by the embodiment includes two rotating seats 510, a rotating member 520, a shaft 530, a shaft sleeve 540, and an elastic member 550. The rotating member 520 is arranged between the two rotating seats 510, the shaft 530 penetrates the two rotating seats 510 and the rotating member 520, and the shaft sleeve 540 can be threadedly connected to the shaft 530.

[0106] The two rotating seats 510 provided by the first embodiment are oppositely arranged on a side of the base 100 facing away from the bottom surface 100a. The rotating seats 510 are protruded from the base 100. The base 100 has a first through hole 510a penetrating the rotating seats 510 in a direction parallel to the bottom surface 100a. The first through hole 510a is used to accommodate the shaft 530, the shaft sleeve 540, and the elastic member 550. The shape, material, and thickness of the rotating seats 510 are not limited in the embodiment.

[0107] The rotating member 520 is arranged at one end of the first support member 210 close to the base 100. The rotating member 520 can be connected to the first support member 210 by clamping, welding, or bonding, or the rotating member 520 and the first support member 210 can be integrally formed. The rotating member 520 has a second through hole 530a penetrating the rotating member 520 in a direction parallel to the bottom surface 100a, and the second through hole 530a is sleeved on the shaft 530. The shape, material, and thickness of the rotating member 520 are not limited in the embodiment.

[0108] The shaft 530 has a first connecting end 531 and a second connecting end 532. The first connecting end 531 is connected to one side of the rotating seat 510. The connection mode includes, but is not limited to, clamping, bonding, and the like. The second connecting end 532 has a threaded hole for connecting the shaft sleeve 540. The radial dimension of the second connecting end 532 is smaller than the radial dimension of the first through hole 510a, and the radial dimension of the second connecting end 532 is the same as the size of the second through hole 530a, so that the second connecting end 532 can penetrate the rotating seat 510, and the rotating member 520 is sleeved on the circumferential side of the second connecting end 532. The shape, material, and thickness of the shaft 530 are not limited in the embodiment.

[0109] The shaft sleeve 540 has a third connecting end 541 and a fourth connecting end 542. The fourth connecting end 542 has threads matched with the second connecting end 532. The fourth connecting end 542 is screwed with the second connecting end 532, so that the shaft sleeve 540 can be fixed on the shaft 530. The shape, material, and thickness of the shaft sleeve 540 are not limited in the embodiment.

[0110] The elastic member 550 is a spring. The elastic member 550 has a first state and a second state. The first state is an extended state, and the second state is a compressed state. The elastic member 550 is sleeved on the shaft 530. The two ends of the elastic member 550 in the extension direction abut against the shaft 530 and the shaft sleeve 540, respectively.

[0111] In an embodiment, when the first support 210 and the base 100 need to keep a fixed posture, the shaft sleeve 540 is screwed with the shaft 530, one end of the shaft sleeve 540 presses the elastic member 550, so that the elastic member 550 is compressed, the elastic member 550 is deformed from the first state to the second state, and the elastic member 550 abuts against the rotating member 520. When the side close to the first connecting end 531 of the elastic member 550 reaches the compression limit by pressing, the side close to the first connecting end 531 of the elastic member 550 is pressed towards the rotating member 520, and the side close to the third connecting end 541 of the elastic member 550 is also pressed towards the rotating member 520, so as to limit the rotation of the rotating member 520, thereby preventing the first support 210 from rotating relative to the base 100.

[0112] In an embodiment, when the first support 210 and the base 100 need to change a posture, the shaft sleeve 540 is unscrewed from the shaft 530, one end of the shaft sleeve 540 releases the elastic member 550, so that the elastic member 550 is stretched, the elastic member 550 is deformed from the second state to the first state, and the elastic member 550 releases the rotating member 520, so that the rotating member 520 can rotate around the shaft 530, thereby realizing the rotation of the first support 210 relative to the base 100.

[0113] It can be understood that in other embodiments, the rotating structure can also be arranged at the connection between the first support 210 and the second support 220, and the connection between the second support 220 and the to-be-supported member 20. The specific connection mode is as described above, which will not be repeated here.

[0114] In the embodiment, the shaft 530, the shaft sleeve 540 and the elastic member 550 are arranged in the rotating structure. Through the cooperation of the shaft 530 and the shaft sleeve 540, the elastic member 550 is arranged between the shaft 530 and the shaft sleeve 540 to limit or loosen the rotation of the rotating member 520, so that the first support 210 and the base 100 can be adjusted in angle and posture according to actual needs of a user, and the user experience is improved.

[0115] Please refer to Figure 12 , Figure 12 The planar schematic view of the base provided in an embodiment of the present application.

[0116] The support device 10 further comprises at least one suction accessory 610, at least one air pipe 620, a one-way valve 630, and a switch 640. The switch 640 is arranged on the base 100. One end of the one-way valve 630 is connected to the switch 640, and the other end is connected to the at least one air pipe 620. Each air pipe 620 is connected to one suction accessory 610. The at least one suction accessory 610 is arranged on the side of the base 100 away from the support assembly 200.

[0117] The suction accessory 610 can be a suction disc structure. The suction accessory 610 is fixedly connected to the base 100. The connection manner includes but is not limited to clamping, bonding, or being integrally formed with the base 100. The suction accessory 610 has a suction surface 610a. The suction surface 610a includes but is not limited to a circular arc surface. The suction surface 610a is recessed towards the side away from the base 100. The suction surface 610a can be detachably or adsorptively arranged on a to-be-supported member 20. The to-be-supported member 20 includes but is not limited to a platform, a table top, a ground, and a structure with a horizontal surface, etc. Optionally, four suction accessories 610 are arranged on the side of the base 100 away from the support assembly 200. The four suction accessories 610 are arranged opposite to each other. The suction accessories 610 are adsorptively arranged on the to-be-supported member 20. The adsorption forces of the four suction accessories 610 are uniformly distributed. The stability of the support device 10 is improved.

[0118] The air pipe 620 is used to supply air to the suction accessory 610. One end of the air pipe 620 is connected to the one-way valve 630. The suction accessory 610 has an air hole 610b arranged on the side away from the suction surface 610a. The other end of the air pipe 620 is connected to the air hole 610b. Optionally, the air hole 610b is arranged in the central region of the suction surface 610a. When air flows into the air hole 610b, the air can be uniformly diffused around the air hole 610b. The suction accessory 610 can be separated from the to-be-supported member 20. The shape, material, and thickness of the air pipe 620 are not limited in particular.

[0119] The switch 640 is arranged on the base 100. Optionally, the switch 640 is arranged on the side of the base 100 perpendicular to the bottom surface 100a. The switch 640 is connected to the one-way valve 630. The switch 640 is used to open or close the one-way valve 630. The shape, material, and thickness of the switch 640 are not limited in particular.

[0120] The one-way valve 630 is arranged on the bottom surface 100a close to the switch 640, and the gas flows from one end of the one-way valve 630 to the air holes 610b of the suction members 610 through the gas pipes 620. The shape, material and thickness of the one-way valve 630 are not limited in the embodiment.

[0121] In one embodiment, the at least one suction member 610 is used to adsorb the base 100 to the to-be-supported member 20, and the switch 640 is used to make the gas enter the one-way valve 630 and then enter the at least one suction member 610 through the at least one gas pipe 620, so as to separate the base 100 from the to-be-supported member 20.

[0122] It can be understood that when the base 100 is placed on the to-be-supported member 20, the switch 640 is in a closed state, and the gas cannot flow from the one-way valve 630 to the gas pipe 620. The suction member 610 is adsorbed to the to-be-supported member 20, so that the support device 10 can be stably placed on the to-be-supported member 20. The connection force between the base 100 and the to-be-supported member 20 is improved, and the support stability of the support device 10 is improved.

[0123] Further, when the base 100 needs to be moved, the switch 640 is opened, the gas flows from the one-way valve 630 to the gas pipe 620, and then flows to the air holes 610b of the suction members 610 through the gas pipes 620. The gas flows out from one end of the adsorption surface 610a, so that the adsorption surface 610a is separated from the to-be-supported member 20. In order to move the base 100, the convenience of use of the user is improved.

[0124] In the embodiment, a plurality of suction members 610 are arranged on the side of the base 100 away from the support assembly 200. On the one hand, the connection force between the base 100 and the to-be-supported member is enhanced, and the support stability of the support device 10 is improved. At the same time, the length and width dimensions of the base 100 can be appropriately reduced, the material of the base 100 is reduced, and the occupied space of the base 100 is saved. On the other hand, by arranging the switch 640, the one-way valve 630 and the gas pipe 620 on one side of the base 100, the suction members 610 can be easily separated from the to-be-supported member 20, the maneuvering sensitivity of the support device 10 is further improved, and the user experience is improved.
