Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 2, an embodiment of the present invention provides a rotating assembly B, including:

a first joint 1, wherein one side or two sides of the first joint 1 are provided with rotating tiles 11;

a second joint 2, wherein one side or two sides of the second joint 2 are provided with a rotating shaft 21;

the inner arc surface of the rotating tile 11 forms a rotating space 12 matched with the rotating shaft 21, and the rotating tile 11 is sleeved with the rotating shaft 21 to form rotating fit.

In the embodiment of the invention, the first joint 1 can have two structures, and for the first joint 1, the two sides are provided with the rotating tiles 11; the second joint 1 is provided with a rotation shoe 11 on one side. Correspondingly, the second joint 2 can have two structures, and the two sides of the first second joint 2 are provided with the rotating tiles 11; the second joint 2 of the second type has a rotation shaft 21 provided on one side thereof. The first joint 1 may be referred to as a female joint and the second joint 2 may be referred to as a male joint.

Thus, for the first joint 1, because the two sides of the first joint are provided with the rotating shoes 11, the first joint 1 can be sleeved with the two second joints 2; as for the first second joint 2, since the rotation shafts 21 are provided on both sides thereof, the second joint 2 can be coupled to the two first joints 1. Since the second type of first joint 1 is provided with the rotation shoe 11 only on one side thereof, the first type of joint 1 can be fitted to only one second joint 2; since the second joint 2 is provided with the rotation shaft 21 only on one side thereof, the second joint 2 can be fitted to only one first joint 1.

In particular, as shown in fig. 3 to 9, the first joint 1 and the second joint 2 should cooperate to form a hinge a with a rotation function. If the hinge a is to be formed, at least one first joint 1 and at least one second joint 2 are required, and these first joint 1 and second joint 2 need to be connected alternately in order. The joints at two ends of the hinge A can be a first joint 1 of a second type or a second joint 2 of the second type; the joint located in the middle of the hinge a should be a first joint 1 and/or a second joint 2 of a first type.

The rotation angle (or bending angle) and the rotation amplitude (or bending amplitude) of the hinge A are related to the number of the joints and the size of the joints, and the larger the number of the joints is, the larger the rotation angle of the hinge A is; the larger the size of the joint is, the larger the rotation amplitude of each joint of the hinge A is. If the rotation angle of the hinge a is as large as possible and the rotation amplitude of each joint of the hinge a is as small as possible, the thickness of the joint may be set as small as possible and the number of joints may be set as large as possible.

In addition, the reduction of the gap between two adjacent joints is also beneficial to enabling the rotation amplitude of each joint of the hinge A to be as small as possible, and the arrangement of each joint of the hinge A can be more compact. In order to reduce the gap between the adjacent two joints, the first joint 1 may be configured to be more compact, and the second joint 2 may be configured to be more compact.

However, if the structure of the first joint 1 is made more compact, the axial line 111 of the rotating shoe 11 can be arranged as close as possible to the central axis of the first joint 1. Thus, the first joint 1 may be provided with a first concave arc surface 112, and the first concave arc surface 112 and the inner arc surface of the rotating tile 11 may jointly form the rotating space 12.

If the second joint 2 is configured to be more compact, the axis 211 of the rotating shaft 21 may be disposed as close to the central axis of the second joint 2 as possible. Thus, the second joint 2 may be provided with a second concave arc surface 212, and the second concave arc surface 212 may form an arc gap 22 with the outer arc surface of the rotating shaft 21 to match with the rotating shoe 11.

The hinge a in the embodiment of the present invention may be used to connect two components that need to be rotated relative to each other, as shown in fig. 10, and may be used for a foldable or foldable electronic device that includes a first base 3 and a second base 4, and the first base 3 and the second base 4 are connected by the hinge a. When the first base body 3 and the second base body 4 of the electronic device are folded or folded relatively, each joint of the hinge a needs to rotate relatively, so that the hinge a bends along with the rotation of the joint.

When the hinge A is connected with the first base body 3 and the second base body 4, the hinge A can be directly connected with the first base body 3 and the second base body 4 through joints at two ends of the hinge A respectively, and connecting pieces 5 can also be arranged at two ends of the hinge A and are connected with the first base body 3 and the second base body 4 through the connecting pieces 5 respectively. This connecting piece 5 can set up to the structure with first base member 3 and second base member 4 matched with to make hinge A and the connection of first base member 3 and second base member 4 simple, convenient, swift more.

In an embodiment of the present invention, the electronic Device may be a Computer (Computer), a Mobile phone, a tablet personal Computer (tablet personal Computer), a Laptop Computer (Laptop Computer), a personal digital assistant (PDA for short), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), an electronic reader, a navigator, a digital camera, and the like.

Taking a mobile phone as an example, the electronic device may be a foldable dual-screen mobile phone or a foldable flexible-screen mobile phone. For a foldable dual-screen mobile phone, a first display screen can be arranged on the first base body, and a second display screen can be arranged on the second base body. For the foldable flexible screen mobile phone, the first base body and the second base body can be provided with the flexible display screen which is connected into a whole.

When the hinge A is bent, one ends of the joints of the hinge A, which are far away from the rotating part (the rotating shaft 21 or the rotating tile 11), can be mutually opened (or unfolded), in order to improve the integrity of the hinge A, the adjacent first joint 1 and the second joint 2 of the hinge A can be connected through a flexible connecting belt 6, and the flexible connecting belt 6 can be stretched or folded along with the opening and closing of the adjacent first joint 1 and the adjacent second joint 2.

The flexible connecting belt 6 may be an elastic connecting belt, or an inelastic connecting belt.

Optionally, a flexible connecting strap 6 is attached to opposing side walls adjacent the first and

second joints

1, 2.

Because the flexible connecting belt 6 is attached between the first joint 1 and the second joint 2, on one hand, when the hinge A is in a bending state, the flexible connecting belt 6 can not expose the surface of the joint, and the integrity and the attractiveness of the hinge when each joint is opened can be improved; on the other hand, when the hinge A is in a flat state, the flexible connecting belt 6 can be well hidden between two adjacent joints, and the flexible connecting belt 6 is guaranteed to be well formed when being reset.

In addition, flexible connection area 6 can seal and connect adjacent first joint 1 and second joint 2, like this, when hinge A was in the state of buckling, flexible connection area 6 can seal the clearance between each joint, not only can improve hinge A's waterproof dustproof performance effectively, can also cover hinge A's inner structure, is favorable to improving hinge A's wholeness and aesthetic property.

Alternatively, the rotation shoe 11 is provided at an end of the first joint 1, and the rotation shaft 21 is provided at an end of the second joint 2.

In the embodiment of the present invention, if the gap between the first joint 1 and the second joint 2 is large enough to provide a sufficient rotation distance when the first joint 1 and the second joint 2 rotate relatively, both the rotation shoe 11 and the rotation shaft 21 may not be necessarily disposed at the end of the joint. As described above, the smaller the gap between the first joint 1 and the second joint 2 is, the smaller the rotation range of each joint of the hinge a is, and the more compact the arrangement of each joint of the hinge a is. Therefore, while the gap between the first joint 1 and the second joint 2 is reduced, the joint ends near the rotation center may restrict the rotation. In this way, the pivot shoe 11 can be provided at the end of the first joint 1, and the pivot shaft 21 can be provided at the end of the second joint 2. Thus, the end of the joint where the rotation shoe 11 or the rotation shaft 21 is provided can be a rotation center, and the other end of the joint can be opened or closed with rotation as a free end.

Optionally, an end surface where the rotation shoe 11 of the first joint 1 is located is a plane, and an end surface where the rotation shaft 21 of the second joint 2 is located is a plane.

In the case where the rotation shoe 11 is provided at the end of the first joint 1, the end surface of the first joint 1 where the rotation shoe 11 is located may be a plane; in the case where the rotation shaft 21 is provided at the end of the second joint 2, the end surface of the second joint 2 where the rotation shaft 21 is located may be a flat surface.

Accordingly, the end surface of the first joint 1 remote from the rotation shoe 11 may be a flat surface, and the end surface of the second joint 2 remote from the rotation shaft 21 may be a flat surface.

Thus, when the hinge A is in a closed state, the end face of the hinge A forms a horizontal attaching surface. Alternatively, the upper and lower surfaces of the hinge a may form a horizontal attachment surface without bending the hinge a. Taking the hinge A for a foldable double-screen mobile phone as an example, when the double-screen mobile phone is opened, the hinge A is in a flat state, and the end surfaces of all joints are positioned on the same plane, so that the connection between the hinge A and the double-screen mobile phone is more attractive.

Optionally, the hinge a is formed by sequentially connecting a plurality of first joints 1 and a plurality of second joints 2 in a staggered manner;

when the hinge A is in a folding state, the end face of the hinge A forms a horizontal attaching surface;

when the hinge A is in an opening state, the end face of the hinge A forms an arc-shaped attaching surface.

In order to make the surface formed by bending the hinge A as smooth as possible, the thickness of the joints should be reduced and the number of joints should be increased. Thus, the end faces of all the joints can form an approximately smooth arc-shaped surface when the hinge A is bent. In this embodiment, the hinge a has better bending performance, and the electronic device is not easily damaged by bending of the hinge a. Taking the hinge A as an example for a foldable flexible screen mobile phone, when the hinge A is in a flat state, the flexible screen can be well laid on the hinge A due to the fact that the surface of the hinge A is a horizontal attaching surface; when hinge A was in the state of buckling, because hinge A's the surface towards flexible screen forms the arc surface of laminating to, its length towards the surface of flexible screen can not change, and flexible screen can be the arc along with buckling of hinge A and buckle, and the flexible screen after buckling also can paste in hinge A's surface well.

Optionally, adjacent first joints 1 and adjacent second joints 2 of the hinge a are connected by a limiting member, and the limiting member can limit the relative sliding between the adjacent first joints 1 and the adjacent second joints 2 along the axial direction of the rotating shaft 21.

The limiting member may be a support rod (not shown in the drawings) connecting two adjacent joints, the support rod is disposed at an end of the joint far from the rotating portion (the rotating shaft 21 or the rotating tile 11), the support rod can only be opened along with the opening of the joint and closed along with the closing of the joint, and the support rod cannot be deflected along the axial direction of the rotating shaft. Therefore, the adjacent two joints can not relatively slide along the axial direction of the rotating shaft under the limitation of the supporting rod, and the dislocation of each joint can be effectively prevented.

Optionally, the limiting member is a pin 7, the pin 7 connects the adjacent first joint 1 and the second joint 2, and the pin 7 is disposed at an end of the joint where the rotating portion (the rotating shaft 21 or the rotating shoe 11) is disposed.

Optionally, each joint of the hinge a is provided with a routing through hole 8, and the adjacent first joint 1 of the hinge a is communicated with the routing through hole 8 of the second joint 2.

When the hinge a is applied to an electronic device, the electronic device may be provided with a wiring from the first base to the second base to implement the related function. For example, when hinge a is used in a foldable dual-screen mobile phone, it may be necessary to provide the two display screens with associated wiring. Therefore, for the convenience of circuit arrangement, the communicated routing through holes 8 can be formed in each joint. Therefore, the circuit inside the electronic equipment can be hidden in the hinge A, the circuit can be protected, and the integrity and the attractiveness of the electronic equipment can be improved.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
