The third friction wheel 63 and the fourth friction wheel 64 are both slidably connected to the second rotation shaft 4 and are both not rotatable about the second rotation shaft 4. The third friction wheel 63 is abutted against the third rotating wheel 53, and an elastic piece 7 is arranged on the end surface of the third friction wheel 63 far away from the third rotating wheel 53; the fourth friction wheel 64 abuts against the fourth rotating wheel 54, and an end surface of the fourth friction wheel 64 away from the fourth rotating wheel 54 is provided with an elastic member 7.
Specifically, the first bracket 1 is provided at both ends thereof with one rotating wheel 5, which will be referred to as a first rotating wheel 51 and a second rotating wheel 52 for convenience of description. The first rotating wheel 51 and the second rotating wheel 52 are fixedly connected to the first bracket 1, and the first rotating wheel 51 and the second rotating wheel 52 can be integrally formed with the first bracket 1. The first rotating wheel 51 and the second rotating wheel 52 are both sleeved on the first rotating shaft 3 and are in rotating connection with the first rotating shaft 3, so that the first bracket 1 can also rotate around the first rotating shaft 3. Similarly, the second bracket 2 is also provided at both ends thereof with one rotating wheel 5, which will be referred to as a third rotating wheel 53 and a fourth rotating wheel 54 for convenience of description. The third rotating wheel 53 and the fourth rotating wheel 54 are fixedly connected to the second bracket 2, and the third rotating wheel 53 and the fourth rotating wheel 54 may be integrally formed with the second bracket 2. The third rotating wheel 53 and the fourth rotating wheel 54 are both sleeved on the second rotating shaft 4 and are rotatably connected with the second rotating shaft 4, so that the second bracket 2 can also rotate around the second rotating shaft 4.
When the first and second shafts 3, 4 are fixed to the support in the foldable electronic device, the first bracket 1 can be rotated about the first shaft 3 and the second bracket 2 can be rotated about the second shaft 4. However, at this time, the rotation resistance between the first bracket 1 and the first rotation shaft 3 is small, and the rotation resistance between the second bracket 2 and the second rotation shaft 4 is small, so that the folding screen in the foldable electronic device cannot be kept in a certain unfolded state. Therefore, a certain rotation resistance needs to be applied during the rotation of the first bracket 1 and the first rotation shaft 3, and the second bracket 2 and the second rotation shaft 4, so that the first bracket 1 cannot easily rotate around the first rotation shaft 3, and the second bracket 2 cannot easily rotate around the second rotation shaft 4. So that the folding screen of the foldable electronic device does not automatically unfold in a folded state, and the folding screen can be maintained at a certain angle without continuing to apply external force after being unfolded to the angle.
In an embodiment of the present application, friction wheels 6 are sleeved on the first rotating shaft 3 and the second rotating shaft 4, and the friction wheels 6 can slide along the first rotating shaft 3 or the second rotating shaft 4. And the friction wheel 6 collides with the rotating wheel 5 for increasing the resistance when the rotating wheel 5 rotates, thereby increasing the resistance when the first bracket 1 rotates around the first rotating shaft 3 and increasing the resistance when the second bracket 2 rotates around the second rotating shaft 4.
Specifically, since the first bracket 1 is rotatably connected to the first rotation shaft 3 through the first rotation wheel 51 and the second rotation wheel 52. Therefore, the first rotating shaft 3 is sleeved with the first friction wheel 61 and the second friction wheel 62, and the first friction wheel 61 and the second friction wheel 62 are positioned between the first rotating wheel 51 and the second rotating wheel 52. The first friction wheel 61 and the second friction wheel 62 can slide along the first rotating shaft 3, so that the first wheel and the second rotating wheel 52 are prevented from being blocked, and the rotation of the first bracket 1 is prevented from being influenced. But the first and second friction wheels 61 and 62 cannot rotate around the first rotation shaft 3, otherwise, they rotate with the first and second rotation wheels 51 and 52, and cannot provide rotation resistance to the first and second rotation wheels 51 and 52.
Wherein the first friction wheel 61 collides with the first rotating wheel 51, and the second friction wheel 62 collides with the second rotating wheel 52. The end surface of the first friction wheel 61, which is far from the first rotating wheel 51, is provided with an elastic member 7, and the end surface of the second friction wheel 62, which is far from the second rotating wheel 52, is provided with an elastic member 7. The elastic member 7 is in a compressed state for the purpose of making the first friction wheel 61 collide with the first rotation wheel 51 more tightly and making the second friction wheel 62 collide with the second rotation wheel 52 more tightly to increase the rotation resistance when the first bracket 1 rotates.
Because the damping rotating shaft mechanism is of a symmetrical structure, a third friction wheel 63 and a fourth friction wheel 64 are sleeved on the second rotating shaft 4, and the third friction wheel 63 and the fourth friction wheel 64 are positioned between the third rotating wheel 53 and the fourth rotating wheel 54. Similarly, the third friction wheel 63 and the fourth friction wheel 64 can slide along the second rotation shaft 4 but cannot rotate around the second rotation shaft 4. Wherein the third friction wheel 63 collides with the third rotating wheel 53, and the fourth friction wheel 64 collides with the fourth rotating wheel 54. The end surface of the third friction wheel 63, which is far from the third rotating wheel 53, is provided with an elastic member 7, and the end surface of the fourth friction wheel 64, which is far from the fourth rotating wheel 5, is provided with an elastic member 7. The elastic member 7 is in a compressed state for the purpose of making the third friction wheel 63 collide more tightly with the third rotation wheel 53 and making the fourth friction wheel 64 and the fourth rotation wheel 54 collide more tightly to increase the rotation resistance when the second bracket 2 rotates.
In an embodiment of the present application, in order to increase the friction between the rotating wheel 5 and the friction wheel 6, thereby increasing the resistance provided by the first rotating structure and the second rotating structure, a protrusion is provided on the surface of the rotating wheel 5 close to the friction wheel 6, a groove is provided on the surface of the friction wheel 6 close to the rotating wheel 5, the protrusion is matched with the structure of the groove, and the protrusion and the groove are in a separated state or a matched state when the rotating wheel 5 rotates.
Specifically, as shown in fig. 3, protrusions are provided on each of the first rotating wheel 51, the second rotating wheel 52, the third rotating wheel 53 and the fourth rotating wheel 54, and grooves are provided on each of the first friction wheel 61, the second friction wheel 62, the third friction wheel 63 and the fourth friction wheel 64. It should be noted that the shape and size of the protruding knot on each rotating wheel 5 may be the same or different, and the corresponding grooves on each friction wheel 6 may be the same or different. But the protrusions and recesses on each pair of rotating wheels 5 and friction wheels 6 match. The provision of the protrusions and recesses is intended to increase the rotational resistance provided by the first rotational structure/the second rotational structure, rather than to prevent rotation thereof. Therefore, when the protrusions and the grooves are provided, the protrusions are generally provided in a circular arc shape, and correspondingly, the openings of the grooves are also in a circular arc shape. When the rotating wheel 5 rotates, the bulge can slide out of the groove, so that the friction wheel 6 directly clamps the rotating wheel 5 when the bulge is clamped in the groove, and the first rotating structure/the second rotating structure cannot rotate.
In this embodiment, the elastic members 7 abutting against the first friction wheel 61, the second friction wheel 62, the third friction wheel 63 and the fourth friction wheel 64 may be elastic members 7 of the same specification, or may be elastic members 7 of different specifications, and in this embodiment, springs are used as the elastic members 7.
By providing the first rotating structure and the second rotating structure, that is, adopting the form that the friction wheel 6 and the rotating wheel 5 form an interference, the rotating resistance of the first bracket 1 and the second bracket 2 can be increased, so that the capability of keeping the first bracket 1 and the second bracket 2 at the current position after rotating is increased. However, there may be a problem of insufficient resistance due to the frictional resistance generated by the friction wheel 6 alone, so that the first bracket 1 and the second bracket 2 cannot maintain their rotated angle after being rotated by a certain angle.
In an embodiment of the present application, one or more first damping structures 8 are disposed on the first rotating shaft 3, the first damping structures 8 are located between the two rotating wheels 5 of the first bracket 1, the first damping structures 8 are fixedly connected with the first bracket 1, and the first damping structures 8 are used for increasing the resistance of the first bracket 1 rotating around the first rotating shaft 3. In addition, one or more second damping structures 9 are arranged on the second rotating shaft 4, the second damping structures 9 are located between the two rotating wheels 5 of the second support 2, the second damping structures 9 are fixedly connected with the second support 2, and the second damping structures 9 are used for increasing the resistance of the second support 2 to rotate around the second rotating shaft 4. In this embodiment, the damping rotation shaft mechanism is described by taking a symmetrical structure as an example, so the second damping structure 9 and the first damping structure 8 may have the same structure and size, and the cooperation between the second damping structure 9 and the second rotation shaft 4 and the second support 2 may also be fully referred to the cooperation between the first damping structure 8 and the first rotation shaft 3 and the first support 1.
As shown in fig. 3, the first damping structure 8 includes a first damping ring 81 and a first friction plate 82, where the first damping ring 81 is rotationally connected with the first rotating shaft 3 and is fixedly connected with the first bracket 1. When the first bracket 1 rotates around the first rotating shaft 3, the first bracket 1 may drive the first damping ring 81 to rotate around the first rotating shaft 3, that is, the first damping ring 81 rotates synchronously with the first rotating wheel 51 and the second rotating wheel 52. The first friction plate 82 is slidable along the first rotation shaft 3, but the first friction plate 82 cannot rotate around the first rotation shaft 3, in order to avoid that both the first friction plate 82 and the first damping ring 81 rotate around the first rotation shaft 3, so that friction force cannot be generated between the first friction plate 82 and the first damping ring 81. The first friction plate 82 is mutually abutted with the first damping ring 81, and an elastic piece 7 is arranged on the end face, far away from the first damping ring 81, of the first friction plate 82. The elastic member 7 is used to make the first friction plate 82 collide with the first damping ring 81 more tightly. When the first bracket 1 rotates, the first damping ring 81 is driven to rotate, at this time, the first friction plate 82 is abutted against the first damping ring 81, and the first friction plate 82 cannot rotate along with the first rotating shaft 3, and friction force is generated between the first damping ring 81 and the first friction plate 82 in the rotating process, so that the rotating resistance of the first bracket 1 is increased.
Similarly, the second damping structure 9 includes a second damping ring 91 and a second friction plate 92, where the second damping ring 91 is rotationally connected with the second rotating shaft 4 and is fixedly connected with the second bracket 2. When the second bracket 2 rotates around the second rotation axis 4, the second bracket 2 may rotate the second damper ring 91 around the second rotation axis 4, that is, the second damper ring 91 rotates in synchronization with the third rotation wheel 53 and the fourth rotation wheel 54. The second friction plate 92 is slidable along the second rotation shaft 4, but the second friction plate 92 cannot rotate around the second rotation shaft 4, in order to avoid that both the second friction plate 92 and the second damping ring 91 rotate around the second rotation shaft 4, resulting in no friction between the second friction plate 92 and the second damping ring 91. The second friction plate 92 is in contact with the second damping ring 91, and an elastic member 7 is disposed on an end surface of the second friction plate 92 away from the second damping ring 91. The elastic member 7 serves to make the second friction plate 92 collide with the second damper ring 91 more tightly. When the second bracket 2 rotates, the second damping ring 91 is driven to rotate, at this time, the second friction plate 92 abuts against the second damping ring 91, and the second friction plate 92 does not rotate along with the second rotating shaft 4, and friction force is generated between the second damping ring 91 and the second friction plate 92 in the rotation process, so that the rotation resistance of the second bracket 2 is increased.
The elastic members 7 abutting against the first friction plate 82 and the second friction plate 92 may be the same specification of elastic members 7. In addition, it should be noted that the elastic members 7 abutting against the friction plate and the friction wheel 6 in the embodiment of the present application may be two independent elastic members 7, or may be the same elastic member 7. When the elastic piece 7 is the same elastic piece, one end of the elastic piece 7 is abutted against the end face of the friction wheel 6 away from the rotating wheel 5, and the other end is abutted against the end face of the first friction plate 82/the second friction plate 92 away from the first damping ring 81/the second damping ring 91.
In an embodiment of the present application, referring to fig. 4, fig. 4 is a schematic structural diagram of another damping spindle mechanism according to an embodiment of the present application. Fig. 4 differs from fig. 3 in that both sides of the first damping ring 81 are provided with first friction plates 82, and both sides of the second damping ring 91 are provided with second friction plates 92.
As shown in fig. 4, first friction plates 82 are disposed on both sides of the first damping ring 81, and an elastic member 7 is disposed on an end surface of each first friction plate 82 away from the first damping ring 81. Compared with the first friction plate 82 arranged on one side of the first damping ring 81, the first friction plates 82 are arranged on two sides of the first damping ring 81, so that two side surfaces of the first damping ring 81 are friction surfaces, the rotation resistance of the first damping ring 81 can be doubled, and the rotation resistance of the first bracket 1 is increased.
Similarly, the two sides of the second damping ring 91 are provided with second friction plates 92, and the end face of each second friction plate 92, which is far away from the second damping ring 91, is provided with an elastic piece 7. To increase the rotational resistance of the second bracket 2.
As shown in fig. 4, only one first damping structure 8 is provided on the first shaft 3, and only one second damping structure 9 is provided on the second shaft 4. The first damping structure 8 comprises a first damping ring 81 and first friction plates 82 arranged on two sides of the first damping ring 81, and the two first friction plates 82 are abutted against the first damping ring 81. A first spring 71 is provided between the first friction plate 82 adjacent to the first friction wheel 61 and the first friction wheel 61, and the first spring 71 is in a compressed state. One end of the first spring 71 abuts against the first friction wheel 61, and the other end of the first spring 71 abuts against the first friction plate 82 adjacent to the first friction wheel 61. A second spring 72 is disposed between the first friction plate 82 adjacent the second friction wheel 62 and the second friction wheel 62, the second spring 72 being in a compressed state. One end of the second spring 72 abuts against the second friction wheel 62, and the other end of the second spring 72 abuts against the first friction plate 82 adjacent to the second friction wheel 62.
The second damping structure 9 includes a second damping ring 91 and second friction plates 92 disposed on both sides of the second damping ring 91, and both the second friction plates 92 are abutted against the second damping ring 91. A third spring 73 is provided between the second friction plate 92 adjacent to the third friction wheel 63 and the third friction wheel 63, and the third spring 73 is in a compressed state. One end of the third spring 73 abuts against the third friction wheel 63, and the other end of the third spring 73 abuts against the second friction plate 92 adjacent to the third friction wheel 63. A fourth spring 74 is disposed between the second friction plate 92 adjacent the fourth friction wheel 64 and the fourth friction wheel 64, the fourth spring 74 being in a compressed state. One end of the fourth spring 74 abuts against the fourth friction wheel 64 and the other end of the fourth spring 74 abuts against the second friction plate 92 adjacent to the fourth friction wheel 64.
With the above arrangement, when the first bracket 1 rotates, the first and second friction wheels 61 and 62 can provide rotational resistance to the first and second rotating wheels 51 and 52, respectively, and at the same time, the first friction plates 82 provided at one side or both sides of the first damping ring 81 can provide rotational resistance to the first damping ring 81. Since the first rotating wheel 51, the second rotating wheel 52 and the first damping ring 81 are fixedly connected to the first bracket 1, the above-mentioned rotation resistance can be transmitted to the first bracket 1, so that the first bracket 1 does not automatically rotate around the first rotating shaft 3 without external force. Meanwhile, due to the multiple rotation resistance, when the first bracket 1 rotates around the first rotating shaft 3, a certain external force is needed to drive the first bracket 1 to rotate, so that the stability of the first bracket 1 after rotation is improved.
Similarly, when the second bracket 2 rotates, the third and fourth friction wheels 63 and 64 may provide rotational resistance to the third and fourth rotating wheels 53 and 54, respectively, and at the same time, the second friction plates 92 provided at one side or both sides of the second damping ring 91 may provide rotational resistance to the second damping ring 91. Since the third rotating wheel 53, the fourth rotating wheel 54 and the second damping ring 91 are fixedly connected to the second bracket 2, the above-mentioned rotation resistance can be transmitted to the second bracket 2, so that the second bracket 2 does not automatically rotate around the second rotation shaft 4 without being subjected to external force. Meanwhile, due to the multiple rotation resistance, when the second bracket 2 rotates around the second rotating shaft 4, a certain external force is required to drive the second bracket 2 to rotate, so that the stability of the second bracket 2 after rotation is improved.
When the damping rotating shaft mechanism is applied to the foldable electronic device, since the two screens of the folding screen are respectively connected (directly connected or indirectly connected) to the first bracket 1 and the second bracket 2, and the first bracket 1 and the second bracket 2 are affected by the rotation resistance, a certain force is required when the foldable electronic device is folded or unfolded by a user, so that the folding screen has a certain feeling of being in a certain state in the folding or unfolding process. In addition, after the folding screen is unfolded to a certain angle, the folding screen can maintain the angle under the influence of the increased rotation resistance, so that a user can operate the folding screen to improve the use experience of the user.
In one embodiment of the present application, another damped spindle mechanism is also provided. Referring to fig. 5, fig. 5 is a schematic structural diagram of still another damping spindle mechanism according to an embodiment of the present disclosure. Fig. 5 differs from fig. 4 in that in fig. 5 two first damping structures 8 and two second damping structures 9 are provided.
As shown in fig. 5, two first damping structures 8 are disposed on the first rotating shaft 3, and two second damping structures 9 are also disposed on the second rotating shaft 4. The two first damping structures 8 have the same structure and comprise a first damping ring 81 and first friction plates 82 arranged on two sides of the first damping ring 81, and the two first friction plates 82 are abutted against the first damping ring 81. The connection of the two first damping rings 81 to the first shaft 3, the first carrier 1 and the friction wheel 6 is described with reference to the previous embodiments. A fifth spring 75 is disposed between the two first damping structures 8, and specifically, a fifth spring 75 is disposed between the first friction plates 82 that are close to each other in the two first damping structures 8. Both ends of the fifth spring 75 respectively abut against the first friction plates 82 which are close to each other in the two first damping structures 8.
The two second damping structures 9 are also identical in structure, and each second damping structure comprises a second damping ring 91 and second friction plates 92 arranged on two sides of the second damping ring 91, and the two second friction plates 92 are abutted against the second damping ring 91. The connection of the two second damping rings 91 to the second rotation shaft 4, the second bracket 2 and the friction wheel 6 is described with reference to the previous embodiments. The sixth spring 76 is disposed between the two second damping structures 9, and specifically, the sixth spring 76 is disposed between the second friction plates 92 that are close to each other in the two second damping structures 9. Both ends of the sixth spring 76 respectively abut against the second friction plates 92 adjacent to each other in the two second damping structures 9.
Since the first friction plates 82 are arranged on both sides of the first damping ring 81 in each first damping structure 8, the first damping structure has two friction surfaces; similarly, the second damping structure 9 also has two friction surfaces. By arranging two first damping structures 8, four friction surfaces are added for the rotation of the first bracket 1; by providing two second damping structures 9 four friction surfaces are added for the rotation of the second bracket 2. The rotational resistance of the first bracket 1 and the second bracket 2 is further increased.
Furthermore, in an embodiment of the present application, three (or more) first damping structures 8 are disposed on the first rotating shaft 3, and each first damping structure 8 includes a first damping ring 81 and first friction plates 82 disposed on two sides of the first damping ring 81. Three (or more) second damping structures 9 are also arranged on the second rotating shaft 4, and each second damping structure 9 comprises a second damping ring 91 and second friction plates 92 arranged on two sides of the second damping ring 91. The connection of the first damping ring 81 to the first shaft 3, the first bracket 1 and the friction wheel 6 is described with reference to the previous embodiments, and the connection of the second damping ring 91 to the second shaft 4, the second bracket 2 and the friction wheel 6 is described with reference to the previous embodiments. The two adjacent first damping structures 8 are in abutting connection through the elastic piece 7, and the two adjacent second damping structures 9 are in abutting connection through the elastic piece 7.
By arranging three or more first damping structures 8 and second damping mechanisms, the rotation resistance of the first bracket 1 and the second bracket 2 can be further increased, and the stability of the rotating first bracket and the rotating second bracket can be improved. It should be noted that, since the first damping structure 8 is disposed between the two rotating wheels 5 of the first bracket 1, and the second damping structure 9 is disposed between the two rotating wheels 5 of the second bracket 2, it is impossible to provide the first damping structure 8 on the first rotating shaft 3 infinitely, and the second damping structure 9 on the second rotating shaft 4 infinitely, because of the size of the first bracket 1 and the second bracket 2. The specific number of settings may be determined according to the specific dimensions of the first support 1/second support 2 and the first damping structure 8/second damping structure 9.
