[0059] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0060] See also Figures 1 to 11 As shown, the shaft component 100 of the embodiment of the present invention includes a bracket 1, a swing arm 2, a support member 3 and a connecting rod 4. The swing arm 2 is rotatably connected to the bracket 1, and the swing arm 2 can swing around the bracket 1. The swing arm 2 is provided with a slide groove 25. The swing arm 2 can be used to connect with other components outside the shaft component 100 to achieve the installation and fixation of the shaft component 100. The support member 3 is rotatably connected to the swing arm 2. The support member 3 includes a connected support member body 31 and a first connecting portion 32. The first connecting portion 32 is provided with a first arc groove 321. The support member body 31 is used to support the screen 8 to keep the screen 8 flat. The support member 3 can be made of lightweight materials such as plastic to reduce its dead weight. In this case, the support member 3 can be made by injection molding to omit the connection step between the support member body 31 and the first connecting portion 32, thereby achieving rapid assembly of the shaft component 100. One end of the connecting rod 4 is rotatably connected to the bracket 1, and the other end of the connecting rod 4 can be slidably matched in the first arc groove 321 and the slide groove 25.

[0061] When the swing arm 2 rotates around the bracket 1, the swing arm 2 drives the connecting rod 4 to rotate around the bracket 1. During this process, one end of the connecting rod 4 slides in the slide groove 25 and the first arc groove 321 at the same time. Since the support member 3 is rotatably connected to the swing arm 2, the connecting rod 4 pulls the support member 3 to rotate around the swing arm 2 when sliding in the slide groove 25.

[0062] Compared with the related art, the rotating shaft component 100 of the embodiment of the present invention has better reliability, a simpler structure and occupies less space.

[0063] In some embodiments, the swing arm 2 includes a rotating portion 21, a first engaging portion 22, a first guiding portion 23, and a second connecting portion 24. Among them, the rotating portion 21 is rotatably connected to the bracket 1, enabling the swing arm 2 to swing around the rotating portion 21. The rotating portion 21 is connected to the first engaging portion 22 and arranged side by side. The first guiding portion 23 is rotatably connected to the support member 3. A sliding groove 25 is located on the first guiding portion 23.

An arc-shaped second guide portion 311 is provided on the support body 31 , and the second guide portion 311 is rotatably connected to the second shaft groove 234 .

[0069] Figure 4 This is a schematic diagram of the support member 3 and the swing arm 2 after being separated, see Figure 4 and Figure 7 As shown, the front end and the rear end of the first guide portion 23 are both provided with a second shaft groove 234 , the second guide portion 311 is installed in the second shaft groove 234 , and the support member 3 can rotate around the second shaft groove 234 .

[0070] In some embodiments, a second stopper 237 is disposed in the second shaft groove 234 , and an outer peripheral surface of the second stopper 237 is at least partially an arc surface. The second guide portion 311 is rotatably engaged between the second stopper 237 and the second shaft groove 234 .

[0071] like Figure 7 As shown, in order to realize the rotational connection between the second guide portion 311 and the second shaft groove 234, a second stopper 237 is arranged above the second shaft groove 234, and the bottom of the second stopper 237 is an arc surface, so that an arc-shaped groove is formed between the second stopper 237 and the second shaft groove 234, and the second guide portion 311 is an arc-shaped plate, and the second guide portion 311 is inserted between the second stopper 237 and the second shaft groove 234 and can rotate between the second stopper 237 and the second shaft groove 234.

[0072] In some embodiments, the first guiding portion 23 includes a first part 231, a second part 232, and a third part 233 that are sequentially connected. The first part 231 and the third part 233 are arranged side by side and at intervals. The first part 231 is connected to the other end of the second connecting portion 24. The second part 232 is located on the side of the first part 231 away from the second connecting portion 24. Second shaft grooves 234 are provided on the sides of the first part 231 and the third part 233 away from the second part 232. The second stopper 237 extends along the second part 232 to the second shaft grooves 234. The side wall of the second stopper 237 is spaced from the side wall of the second shaft grooves 234 to accommodate the second guiding portion 311.

[0073] As Figure 7 shown, the first part 231, the second part 232, and the third part 233 are integrally connected. The left end of the first part 231 is connected to the right end of the second connecting portion 24. The second part 232 and the rotating portion 21 are both located at the rear side of the second connecting portion 24. Second shaft grooves 234 are provided at the front end of the first part 231 and the rear end of the third part 233. The second stopper 237 is fixedly connected to the second part 232. The chute 25 is opened on the end surface of the third part 233 opposite to the first part 231. One end of the connecting rod 4 having the second pin shaft 42 is arranged between the first part 231 and the second part 232. The above-mentioned first connecting portion 32 is arranged between the connecting rod 4 and the third part 233.

[0074] As Figure 3 shown, at this time, the swing arm 2 and the bracket 1 are in the same plane. The upper end surface of the support member body 31 is flush with the upper end of the bracket 1. The support member body 31 is used to support the screen 8. Figure 3 In, the swing arm 2 on the right side of the bracket 1 rotates counterclockwise around the first pin shaft 41, and the swing arm 2 on the left side of the frame body rotates clockwise around the first pin shaft 41. During the rotation of the swing arm 2 around the bracket 1, the second pin shaft 42 slides in the chute 25 and the first arc groove 321 at the same time, and the second pin shaft 42 gradually approaches the bracket 1. At the same time, under the action of the second pin shaft 42, the support member 3 rotates by a certain angle around the second shaft groove 234. In Figure 3 In, the swing arm 2 on the right side of the frame body and the swing arm 2 on the left side of the frame body can rotate to the Figure 2 state shown after rotating 90 degrees. As Figure 2 shown, at this time, the two swing arms 2 are parallel to each other, while there is an included angle between the two support member bodies 31. A space that is narrow at the top and wide at the bottom is formed between the two support member bodies 31 and the bracket 1. The above-mentioned space can be used to accommodate the bent area of the screen 8. Since the lower part of this space is wider, the screen 8 can be prevented from being bent excessively.

[0075] In some embodiments, the bracket 1 is further provided with a supporting portion 13 for supporting the second connecting portion 24. The supporting portion 13 extends along the direction from the rotating portion 21 to the first engaging portion 22. A notch 241 corresponding to the supporting portion 13 is provided on the side of the second connecting portion 24 facing away from the first guiding portion 23. As Figure 6 shown, the front end of the bracket 1 has two supporting portions 13, and the two supporting portions 13 are spaced apart to form a notch for cooperating with the first limiting member 51 between the two supporting portions 13. As Figure 7 shown, the above-mentioned notch 241 is opened at the bottom of the second connecting portion 24. The provided notch 241 is used to prevent interference between the swing arm 2 and the supporting portion 13 during rotation.

[0076] In some embodiments, the bearing surfaces of the first portion 231 and the third portion 233 are inclined surfaces 235, and first mounting holes 236 are provided on the bearing surfaces of the first portion 231 and the third portion 233. As Figure 7 shown, inclined surfaces 235 are provided at the upper left ends of the first portion 231 and the third portion 233, so that the thickness of the left ends of the first portion 231 and the third portion 233 is smaller than that of the right ends. By providing the inclined surfaces 235, interference between the support member body 31 and the first portion 231 and the third portion 233 during rotation is avoided. The inclination angle of the above-mentioned inclined surfaces 235 can be determined according to Figure 2 the included angle between the two support member bodies 31. First mounting holes 236 are opened on the first portion 231 and the third portion 233. The first mounting holes 236 are used to fix the swing arm 2 to the housing 7.

[0077] In some embodiments, the bracket 1 is further provided with a hinged portion 15. One end of the connecting rod 4 is hinged to the hinged portion 15. The third portion 233 is spaced from the rotating portion 21 of the swing arm 2. Sliding grooves 25 are provided on two opposite side surfaces of the first portion 231 and the third portion 233. The openings of the sliding grooves 25 face the side of the rotating portion 21 of the swing arm 2. The other end of the connecting rod 4 is slidably engaged in the sliding grooves 25.

A second torsion portion 531 cooperating with the first torsion portion 511 is provided at one end of the torsion member 53.

[0086] The second limiting member 54 is provided at the end of the transmission member 52 away from the first limiting member 51. The elastic member 55 is sleeved on the outside of the transmission member 52. One end of the elastic member 55 abuts against the torsion member 53, and the other end of the elastic member 55 abuts against the second limiting member 54. As Figure 8 shown, the second limiting member 54 is fixed to the end of the transmission member 52 away from the first limiting member 51. The elastic member 55 is sleeved on the outside of the transmission member 52 and is located between the first limiting member 51 and the second limiting member 54. The elastic member 55 applies a thrust force to the torsion member 53. When the swing arm 2 rotates, the torsion member 53 rotates synchronously with the transmission member 52. The second torsion portion 531 on the torsion member 53 cooperates with the first torsion portion 511 on the first limiting member 51. Under the elastic force of the elastic member 55, the second torsion portion 531 on the torsion member 53 is in close contact with the first torsion portion 511 on the first limiting member 51, and the torsion member 53 moves away from or approaches the first limiting member 51.

[0087] When the torsion member 53 approaches the first limiting member 51, the first torsion portion 511 and the second torsion portion 531 are engaged with each other. At this time, a certain amount of force needs to be applied to the swing arm 2 to make the swing arm 2 rotate. At this time, the swing arm 2 correspondingly is in the closed position as Figure 2 shown or the flattened position as Figure 3 shown. Therefore, the locking of the swing arm 2 in the flattened position and the closed position is realized. When the torsion member 53 moves away from the first limiting member 51, the first torsion portion 511 and the second torsion portion 531 are in contact with each other. At this time, a relatively large force does not need to be applied to the swing arm 2 to make the swing arm 2 rotate, and the swing arm 2 is in a position between the flattened position and the closed position. Thus, it is ensured that the swing arm 2 can be easily switched from the flattened position to the closed position.

[0088] In some embodiments, a second through hole 14 is provided on the bracket 1. One end of the transmission member 52 adjacent to the bracket 1 is rotatably fitted in the second through hole 14. As Figure 6 shown, two second through holes 14 are provided at the front end of the bracket 1. The distance between the two second through holes 14 is equal to the distance between the two first torsion portions 511. One end of the transmission member 52 is inserted into the second through hole 14 and can rotate in the second through hole 14. Thus, the limitation of the end of the transmission member 52 is realized, and the shaking of the transmission member 52 can be effectively prevented.

[0089] In some embodiments, a second engaging portion 521 is provided at one end of the transmission member 52. The first engaging portion 22 of the swing arm 2 is engaged with the second engaging portion 521. As Figure 11As shown, the second engaging portion 521 is fixedly connected to the transmission member 52. The second engaging portion 521 rotates synchronously with the transmission member 52. The first engaging portion 22 engages with the second engaging portion 521 to achieve the transmission between the swing arm 2 and the transmission member 52. When the swing arm 2 rotates, the transmission member 52 rotates with the swing arm 2. Among them, the above-mentioned second engaging portion 521 can be a gear, and the first engaging portion 22 is provided with teeth matching the second engaging portion 521.

[0090] In some embodiments, the transmission member 52 is provided with a first limiting portion 522. The torsion member 53 is sleeved on the transmission member 52, and the torsion member 53 is provided with a second limiting portion 532 corresponding to the first limiting portion 522. The first limiting portion 522 and the second limiting portion 532 cooperate to achieve the circumferential limit of the torsion member 53 on the transmission member 52. As Figure 11 shown, a cut surface is arranged along the length direction of the transmission member 52 to form the above-mentioned first limiting portion 522. As Figure 10 shown, a fourth through hole 535 is opened on the torsion member 53. The transmission member 52 is inserted into the fourth through hole 535. The first limiting portion 522 and the second limiting portion 532 cooperate with each other to prevent the torsion member 53 from rotating relative to the transmission member 52, ensuring that the torsion member 53 rotates synchronously with the transmission member 52.

[0091] In some embodiments, the first limiting member 51 is provided with a first groove 512. The bottom of the first groove 512 is provided with a first through hole 513 and a first torsion portion 511. The transmission member 52 is fitted in the first through hole 513. The first torsion portion 511 is arranged on the periphery of the first through hole 513. One end of the torsion member 53 adjacent to the first limiting member 51 is provided with a second torsion portion 531. The second torsion portion 531 and the first torsion portion 511 are slidably fitted. As Figure 9 shown, two first grooves 512 are opened on the front end face of the first limiting member 51. The positions of the first grooves 512 correspond to the positions of the first torsion portions 511 one by one. The first through hole 513 penetrates through the front and rear end faces of the first limiting member 51 and is used for the transmission member 52 to pass through.

[0092] In some embodiments, the cross-sectional area of the first torsion portion 511 gradually increases in the direction from the notch to the bottom of the first groove 512; the torsion member 53 has a first end 533 and a second end 534 in its length direction. The cross-sectional area of the second torsion portion 531 gradually increases in the direction from the first end 533 to the second end 534 of the torsion member 53. In specific implementation, the surfaces of the first torsion portion 511 and the second torsion portion 531 can both be designed as smooth curved surfaces.

[0093] In some embodiments, a third through hole 514 and a second arc-shaped groove 515 are further provided on the first limiting member 51. On one side of the first engaging portion 22 away from the rotating portion 21, a first plug-in member 26 and a second plug-in member 27 are provided. The first plug-in member 26 is rotatably fitted in the third through hole 514, and the second plug-in member 27 is slidably fitted in the second arc-shaped groove 515. The shape of the second arc-shaped groove 515 described above is arc-shaped, and the center of the circle thereof coincides with the center of the third through hole 514. When the first plug-in member 26 rotates in the third through hole 514, the second plug-in member 27 slides in the second arc-shaped groove 515, and the angle range of the swing of the swing arm 2 can be limited by the second arc-shaped groove 515.

[0094] Among them, the central angle corresponding to the second arc-shaped groove 515 is greater than or equal to 90 degrees. When the central angle corresponding to the second arc-shaped groove 515 is equal to 90 degrees, the angle by which the swing arm 2 can rotate relative to the bracket 1 is also 90 degrees. Moreover, when the second plug-in member 27 is at the lowermost end of the second arc-shaped groove 515, the swing arm 2 is in the flattened position; when the second plug-in member 27 is at the uppermost end of the second arc-shaped groove 515, the swing arm 2 is in the closed position. It should be noted that the second arc-shaped groove 515 is mainly used to limit the swing range of the swing arm 2. When there are different requirements for the swing range of the swing arm 2, the central angle corresponding to the second arc-shaped groove 515 can be increased or decreased accordingly.

[0095] In some embodiments, at least part of the upper surface of the bracket 1 and at least part of the upper surface of the first limiting member 51 are both arc surfaces 18, and the extension surfaces of the arc surfaces 18 on the upper surface of the bracket 1 and the extension surfaces of the arc surfaces 18 on the upper surface of the first limiting member 51 coincide. As Figure 6 shown, arc surfaces 18 are provided at the top of the bracket 1 and the top of the first limiting member 51, and the radian of the arc surface 18 at the top of the bracket 1 is equal to the radian of the arc surface 18 at the top of the first limiting member 51. As Figure 2 shown, when the swing arm 2 swings to the state shown in the figure, the bottom of the space formed between the support member body 31 and the bracket 1 is arc-shaped, and at this time, the shape of the above space can match the bending shape of the screen 8.

[0096] As Figure 7 shown, a mating surface 28 is provided at one end of the rotating portion 21 and the first engaging portion 22 adjacent to the first guiding portion 23. When the swing arm 2 rotates to Figure 2 the state shown, the mating surface 28 on the swing arm 2 is tangent to the arc surfaces 18 on the bracket 1 and the first limiting member 51, thereby preventing the swing arm 2 from interfering with the screen 8 and avoiding wear of the screen 8.

[0097] See Figures 1 to 4As shown in the figure, the terminal device according to the embodiment of the present invention includes a shielding member 6, a housing 7, a screen 8, and the above-mentioned rotating shaft component 100. The rotating shaft component 100 is provided inside the shielding member 6. The provided shielding member 6 is used to prevent the rotating shaft component 100 from being exposed during the rotation of the terminal device, protecting the rotating shaft component 100 and enhancing the aesthetic feeling of the terminal device at the same time; the housing 7 is fixedly connected to the swing arm 2, and when the housing 7 rotates, the swing arm 2 rotates synchronously with the housing 7; the screen 8 is a flexible screen and is laid on the housing 7, and the support member 3 is located on the back surface of the screen 8. When the terminal device is in the flattened state, the back surface of the screen 8 contacts the support member body 31. By providing the support member body 31, the support for the screen 8 is realized, preventing the middle part of the screen 8 from collapsing when the terminal device is in the flattened state and keeping the screen 8 flat.

[0098] The above-mentioned housing 7 includes a first housing 71 and a second housing 72 of the same size. The above-mentioned rotating shaft components 100 are two, and the two rotating shaft components 100 are arranged between the first housing 71 and the second housing 72. The two swing arms 2 on the rotating shaft component 100 are respectively fixed to the first housing 71 and the second housing 72. The above-mentioned shielding member 6 is also arranged between the first housing 71 and the second housing 72, and both ends of the shielding member 6 are respectively fixed to the bottom of the brackets 1 on the two rotating shaft components 100. When the terminal device is in the flattened state, the shielding member 6 is hidden in the space between the bracket 1 and the housing 7. Due to the limitation of the support member body 31, the bending part of the screen 8 is approximately in the shape of a water droplet at this time, effectively avoiding excessive bending of the screen 8 and reducing the risk of damage to the screen 8.

[0099] In summary, the rotating shaft component 100 of the embodiment of the present application can be used as the hinge of a foldable terminal device. Compared with the hinge structure in the related art, the rotating shaft component 100 has the advantages of simple assembly, high reliability, small occupied space, and good synchronism. The terminal device using the above-mentioned rotating shaft component 100 in the present application can effectively save the space inside the terminal device, which is beneficial to the development of the terminal device towards being thinner and lighter. At the same time, the rotating shaft component 100 can realize the locking and holding of the terminal device in the flattened / folded state, making the terminal device have a damping feel during the unfolding and folding processes.
