The connecting plate 222 is used to be rotatably connected to the first shaft 15. The connecting side plate 221 is connected to the first enclosure 211 of the first section 21. In this embodiment, the connecting side plate 221 is inserted into the notch 213.

In this embodiment, the rotating slot 224 is arc-shaped, and the number thereof can be two. Each guide body 122 is accommodated in a rotating slot 224, and the guide body 122 can move in the rotating slot 224. The two rotating slots 224 are arranged at intervals around the first axis 15. The rotating slot 224 is configured to limit the rotation angle of the guide body 122, thereby limiting the rotation angle of the rotating body 10 relative to the support body 20. In other possible embodiments, the rotating slot 224 is annular, and the number thereof can be one, and two guide bodies 122 can be accommodated in one rotating slot 224 and move therein.

The hole axis of the second through hole 226 is the same as the length direction of the second section 22.

[0061] The second sub-channel 225 is connected to the first sub-channel 212 for the cable 300 to pass through. The extension direction of the second sub-channel 225 is the same as the length direction of the second section 22, and the extension direction of the second sub-channel 225 intersects with the extension direction of the first sub-channel 212. The first sub-channel 212 and the second sub-channel 225 together constitute the second channel 24 of the channel described above. It can be understood that the support body 20 includes the second channel 24. In this embodiment, the cable 300 can be sequentially arranged in the second sub-channel 225 and the first sub-channel 212 without being exposed to the housing 40, which not only avoids the complicated routing of the cable 300, but also ensures that the appearance of the electronic device is simple and beautiful. Since the cable 300 is arranged inside the support body 20, the wear of the cable 300 by the rotating support structure 100 is reduced when rotating.

[0062] In other possible embodiments, the second section 22 includes a second enclosure. The second enclosure is connected to the first enclosure 211. One end of the second enclosure is embedded in the notch 213. The second enclosure forms a second sub-channel 225 and a second through hole 226. The second enclosure is provided with a first fixing hole 2231 and a rotating slide groove 224 on one side facing the rotating body 10.

[0063] In this embodiment, the second section 22 is a hollow steel pipe structure. The second section 22 can be made by a square pipe stamping process, thereby reducing the production cost of the steel pipe.

[0064] A limiting plate 23 is arranged between the connecting plate 222 of the second section 22 and the bottom plate 12 of the rotating body 10, and a limiting slot 231 is provided on the limiting plate 23, and the limiting slot 231 runs through two surfaces of the limiting plate 23 in the thickness direction. The limiting slot 231 is used for the guide body 122 to pass through, and the guide body 122 passes through the limiting slot 231 and extends into the rotating slot 224. In this embodiment, the limiting slot 231 is arc-shaped, and the number of the limiting slots 231 is two. Each limiting slot 231 is arranged corresponding to a rotating slot 224, and the shape of the limiting slot 231 is consistent with the shape of the rotating slot 224, both of which are arc-shaped. The limiting slot 231 is configured to limit the rotation angle of the guide body 122, that is, the limiting plate 23 plays a role in limiting the rotation angle of the rotating body 10 relative to the support body 20. The limiting plate 23 can be made of a copper sheet or a rubber sheet. In other possible embodiments, the limiting sliding groove 231 is annular, and there is one of them.

[0070] The fixing body 37 is convexly arranged on the second surface 32 and is arranged at the edge of the mounting hole 33. The fixing body 37 is used to connect with the third housing 43 to realize the connection between the mounting plate 30 and the third housing 43. In this embodiment, the number of the fixing bodies 37 is two. The two fixing bodies 37 are arranged at intervals on the same side edge of the mounting hole 33. In this embodiment, the mounting plate 30 is connected to the third housing 43 through the fixing body 37 and the clamping hole 34. The fixing body 37 and the clamping hole 34 are respectively arranged on opposite sides of the mounting hole 33.

[0071] Please refer to Figures 6 to 9 , Fig. 9 for Figure 3 The structural diagram of the partial structure of the rotating support structure shown in FIG. Fig. 9 The housing 40 is not shown, which is only for illustrating the rotational connection relationship between the mounting plate 30 , the rotating body 10 and the supporting body 20 , and does not represent the assembly sequence of the rotating supporting structure 100 .

[0072] The first section 21 of the support body 20 is connected to the electronic device body, and the second section 22 of the support body 20 is connected to the rotating body 10. It can be understood that the end of the rotating body 10 away from the mounting plate 30 is connected to the second section 22. The limit plate 23 is connected between the second section 22 and the rotating body 10, reducing the friction generated when the rotating body 10 rotates relative to the second section 22, thereby protecting the rotating body 10 and the second section 22 from damage.

[0073] In this embodiment, the first shaft 15 is disposed through the top plate 11 and the bottom plate 12 of the rotating body 10, the stop plate 23, and the connecting plate 222 of the second section 22, and is connected to the rotating body 10 and the supporting body 20 by cooperating with the nut. One end of the first shaft 15 is located on the side of the top plate 11 facing away from the first channel 14. The first shaft 15 passes through the first channel 14 of the rotating body 10, and the other end thereof is located in the second sub-channel 225 of the second section 22.

[0074] In other possible embodiments, the first shaft 15 is disposed through the bottom plate 12 of the rotating body 10, the stop plate 23, and the connecting plate 222 of the second section 22, and is connected to the rotating body 10 and the supporting body 20 by cooperating with the nut. One end of the first shaft 15 is located in the first channel 14 of the rotating body 10, and the other end thereof is located in the second sub-channel 225 of the second section 22.

[0075] Combination Figure 5-Figure 7 As shown, the guide body 122 of the bottom plate 12 is inserted into the limiting slide groove 231 of the limiting plate 23 and the rotating slide groove 224 of the connecting plate 222, and can move in the limiting slide groove 231 and the rotating slide groove 224. In this embodiment, the two guide bodies 122 are symmetrically arranged about the axis of the first shaft 15, the two limiting slide grooves 231 are symmetrically arranged about the axis of the first shaft 15, and the two rotating slide grooves 224 are symmetrically arranged about the axis of the first shaft 15.

[0076] In this embodiment, the angle of rotation of the rotating body 10 relative to the supporting body 20 is related to the limiting slide groove 231 and the rotating slide groove 224. The angle can be set according to the actual needs. The curvature of the limiting slide groove 231 or the rotating slide groove 224 can be any curvature within the range of 0-360 degrees. It can be explained that, with the first direction X as the reference, along the second direction Y, the angle of rotation of the rotating body 10 relative to the supporting body 20 is greater than or equal to 0 degrees and less than or equal to 360 degrees. That is, along the second direction Y, the rotating body 10 can rotate 0 degrees, 150 degrees or 360 degrees relative to the supporting body 20; or, with the first direction X as the reference, along the opposite direction of the second direction Y, the angle of rotation of the rotating body 10 relative to the supporting body 20 is greater than or equal to 0 degrees and less than or equal to 360 degrees, that is, along the opposite direction of the second direction Y, the rotating body 10 can rotate 0 degrees, 150 degrees or 360 degrees relative to the supporting body 20.

[0077] Exemplarily, the arcs of the limiting slide groove 231 and the rotating slide groove 224 are both 60 degrees. It can be explained that, with the first direction X as a reference, along the second direction Y, the angle at which the rotating body 10 rotates relative to the supporting body 20 is greater than or equal to 0 degrees and less than or equal to 30 degrees. That is, along the second direction Y, the rotating body 10 can rotate relative to the supporting body 20 by 0 degrees, 15 degrees, or 30 degrees; or, with the first direction X as a reference, along the opposite direction of the second direction Y, the angle at which the rotating body 10 rotates relative to the supporting body 20 is greater than or equal to 0 degrees and less than or equal to 30 degrees. That is, along the opposite direction of the second direction Y, the rotating body 10 can rotate relative to the supporting body 20 by 0 degrees, 15 degrees, or 30 degrees.

[0078] In this embodiment, the extension direction of the first channel 14 of the rotating body 10 intersects with the extension direction of the first subchannel 212 of the first section 21 , and the hole axis of the first through hole 121 of the rotating body 10 intersects with the hole axis of the second through hole 226 of the second section 22 .

[0079] One end of the rotating body 10 is connected to the mounting plate 30. The first surface 31 of the mounting plate 30 faces away from the rotating body 10, and the second surface 32 of the mounting plate 30 faces the rotating body 10. The first channel 14 of the rotating body 10 is opposite to and connected with the mounting hole 33 of the mounting plate 30. In this embodiment, the two side plates 13 of the rotating body 10 are located between the two connecting bodies 36 of the mounting plate 30. Each second shaft 16 of the rotating body 10 is passed through a side plate 13 and a connecting body 36, and cooperates with a nut to realize the rotational connection between the rotating body 10 and the mounting plate 30. The opening of the limiting opening 361 of the connecting body 36 faces the limiting body 131. The limiting body 131 can be rotatably connected to the limiting opening 361.

[0080] In other possible embodiments, the two connectors 36 of the mounting plate 30 are located between the two side plates 13 of the rotating body 10. The limiting body 131 is located in the first channel 14 of the rotating body 10. The limiting opening 361 of the connector 36 opens toward the limiting body 131. The limiting body 131 is rotatably connected to the limiting opening 361.

[0081] In this embodiment, the angle at which the mounting plate 30 rotates relative to the rotating body 10 is related to the limit opening 361, and the angle can be set according to the actual needs. For example, the arc of the limit opening 361 is 40 degrees. It can be explained that, with the second direction Y as a reference, along the third direction Z, the angle at which the mounting plate 30 rotates relative to the rotating body 10 is greater than or equal to 0 degrees and less than or equal to 25 degrees. That is, along the third direction Z, the mounting plate 30 rotates relative to the rotating body 10 by 0 degrees, 15 degrees or 25 degrees; or, with the second direction Y as a reference, along the opposite direction of the third direction Z, the angle at which the mounting plate 30 rotates relative to the rotating body 10 is greater than or equal to 0 degrees and less than or equal to 15 degrees. That is, along the opposite direction of the third direction Z, the mounting plate 30 rotates relative to the rotating body 10 by 0 degrees, 10 degrees or 15 degrees.

[0082] In this embodiment, the rotating body 10 and the supporting body 20 are rotatably connected via the first shaft 15, and the mounting plate 30 and the rotating body 10 are rotatably connected via the second shaft 16. The axial direction of the first shaft 15 is perpendicular to the axial direction of the second shaft 16, and the rotation direction between the mounting plate 30 and the rotating body 10 is perpendicular to the rotation direction between the rotating body 10 and the supporting body 20, which increases the rotatable range of the rotating support structure 100 and increases the angular range of the display screen 200 connected to the rotating support structure 100 that can rotate relative to the electronic device body (not shown), which is not only convenient for users to watch, but also meets the convenience of using the electronic device (not shown) on site.

[0106] Please refer to Fig.13 and Fig.14 , Fig.14 for Figure 1 The cross-sectional structure diagram of the first embodiment of the cable routing of the electronic device shown is shown. It should be noted that: Fig.14 The cable 300 is shown to highlight the relationship between the cable 300 and the channel, so only the cable 300 is cross-sectioned.

[0110] The same contents between this embodiment and the first embodiment are not repeated here. The difference between the rotating support structure 100 in this embodiment and the rotating support structure 100 in the first embodiment is that the position of the first channel 14 in this embodiment is different from the position of the first channel 14 in the first embodiment.

Among them, the avoidance hole 4251 of the second shell 42 is located in the second channel 24 for the cable 300 to pass through. And along the width direction of the protrusion 223, there is a gap between the two side edges of the protrusion 223 and the through hole 427 of the second sub-shell 422, and the gap is used for the cable 300 to pass through (i.e., the second direction Y). Exemplarily, the cable 300 connected to the circuit board 230 is sequentially penetrated through the threading hole 2101 of the shell 210, the mounting hole 33 of the mounting plate 30, the first channel 14 of the rotating body 10, the gap between the through hole 427 of the second sub-shell 422 and the protrusion 223, and the second channel 24 of the support body 20, and extends to the electronic device body (not shown) to be electrically connected thereto.

The diversified structure of the channel of the rotating support structure 100 makes the storage method of the cable 300 through the rotating support structure 100 diversified, which is convenient for the storage of the cable 300.
