[0040] Combine the following Figures 4 to 13 A hinge structure 100 , a hinge assembly 200 , and an electronic device 300 according to an embodiment of the present application are described.

[0041] like Figure 4 As shown, the present application provides a hinge structure 100, including: a first cam 110, one end of which is provided with a protrusion 112; a second cam 120, which is located on one side of the first cam 110, and the second cam 120 and the first cam 110 are rotatably connected, and the first end surface of the second cam 120 is provided with a damping portion 122 and a guide portion 124, the damping portion 122 and the guide portion 124 are adjacently arranged on the first end surface, and the first end surface is the surface on which the second cam 120 contacts the first cam 110; wherein, when the protrusion 112 is separated from the damping portion 122, the first cam 110 and the second cam 120 can automatically rotate under the action of the guide portion 124.

[0042] In an embodiment of the present application, the hinge structure 100 includes a first cam 110 and a second cam 120, and the first cam 110 and the second cam 120 are rotatably connected. A protrusion 112 is provided at one end of the first cam 110, and a damping portion 122 and a guide portion 124 are provided on the first end face of the second cam 120 facing the first cam 110, and the damping portion 122 and the guide portion 124 are adjacent to each other. When the first cam 110 and the second cam 120 are rotated to the point where the protrusion 112 and the damping portion 122 are separated, the protrusion 112 cooperates with the guide portion 124, so that the protrusion 112 automatically slides along the guide portion 124, thereby realizing the automatic rotation of the first cam 110 and the second cam 120. When the hinge structure 100 is applied to other devices, for example, an electronic device 300, the electronic device 300 can automatically unfold after being opened to a certain angle, thereby reducing the difficulty of operating the electronic device 300.

[0043] Specifically, the first end surface of the second cam 120 may be entirely the damping portion 122 and the guide portion 124 , or may be partially the damping portion 122 and the guide portion 124 .

[0044] When the protrusion 112 slides along the damping portion 122 , an external force is required to do work.

[0045] like Figure 5 As shown, the hinge structure 100 has a first state, a second state and a third state during rotation. The first state is when the user does work to open the hinge, the second state is when the first cam 110 is in an automatic state, and the third state is when the hinge structure 100 is fully opened.

[0046] Specifically, since the relative rotation angle between the first cam 110 and the second cam 120 can be 90 degrees or 180 degrees, the number of the protrusions 112, the damping portions 122 and the guide portions 124 can be set to one group, two groups, three groups or four groups, etc., as long as the protrusion 112 only passes through the damping portion 122 once when the two hinge structures are switched from the folded state to the unfolded state.

[0047] like Figure 6 As shown, during the rotation of the first cam 110 and the second cam 120 in the hinge structure 100 , the hinge structure 100 experiences a first state, a second front state, a second rear state, and a third state.

[0048] In the first state, external work is performed to open the hinge structure 100. In the second front state, the protrusion 112 moves to the end of the damping portion 122 and is about to enter the guide portion 124. In the second rear state, the protrusion 112 slides along the guide portion 124 driven by the elastic member 130. In the third state, the protrusion 112 moves to the end of the guide portion 124 and the hinge structure 100 is fully opened.

[0049] Specifically, the protrusion 112 is provided on the first cam 110 , and the damping portion 122 and the guide portion 124 are provided on the second cam 120 , or the protrusion 112 is provided on the second cam 120 , and the damping portion 122 and the guide portion 124 are provided on the first cam 110 .

[0050] As a possible embodiment, it also includes: an elastic member 130, which is located at one end of the first cam 110 away from the second cam 120 or on the side of the second cam 120 away from the first cam 110, so that the protrusion 112 abuts against one end of the second cam 120 provided with a damping portion 122 and a guide portion 124, and the elastic member 130 is used to drive the protrusion 112 to slide along the guide portion 124.

[0051] Specifically, an elastic member 130 is provided on one side of the first cam 110 and the second cam 120. Under the action of the elastic member 130, the first cam 110 and the second cam 120 are abutted against each other, wherein the protrusion 112 and the first end face are abutted against each other. Specifically, the protrusion 112 is located on one side of the damping portion 122. When the first cam 110 and the second cam 120 rotate, the protrusion 112 cooperates with the damping portion 122, and then the user performs work on the first cam 110 and the second cam 120, so that the cam slides along the damping portion 122. After the protrusion 112 leaves the damping portion 122 and enters the guide portion 124, under the action of the elastic member 130, the protrusion 112 slides along the guide portion 124, thereby realizing automatic rotation of the protrusion 112.

[0052] Furthermore, the elastic member 130 can generate a pre-tightening force on the first cam 110 and the second cam 120 to ensure the stability of the first cam 110 and the second cam 120 .

[0053] like Figure 7As shown, during the rotation of the hinge structure 100, the first cam 110 rotates from 0 degrees to A degrees, which requires external force to do work. Then, under the action of the elastic member 130, the first cam 110 automatically rotates. When it rotates to the point where the first magnetic member 142 and the second magnetic member 144 interact with each other, the elastic force of the elastic member 130 is offset to a certain extent, thereby reducing the friction between the first cam 110 and the second cam 120, making the first cam 110 rotate more smoothly, reducing the wind direction in which the first cam 110 is stuck, and facilitating the automatic rotation of the first cam 110. When the first cam 110 rotates 180 degrees, the hinge structure 100 is fully opened.

[0054] like Figure 4 As shown, as a possible implementation, it also includes: a first magnetic member 142, which is arranged on the first cam 110; a second magnetic member 144, which is arranged on the second cam 120, and the first magnetic member 142 and the second magnetic member 144 form a repulsive force.

[0055] Specifically, a first magnetic member 142 is provided on the first cam 110, and a second magnetic member 144 is provided on the second cam 120. The first magnetic member 142 and the second magnetic member 144 are arranged in a manner that the same magnetic poles are opposite to each other, thereby reducing the pressure between the first cam 110 and the second cam 120, and further reducing the friction between the first cam 110 and the second cam 120, making it easier for the first cam 110 and the second cam 120 to rotate under the action of the elastic member 130.

[0056] The second magnetic member 144 can set the position of the guide portion 124 so that when the first magnetic member 142 and the second magnetic member 144 rotate to relative to each other, the repulsive force between the first magnetic member 142 and the second magnetic member 144 reduces the friction between the first cam 110 and the second cam 120, thereby facilitating the automatic rotation of the first cam 110 and the second cam 120.

[0057] Among them, the end face of the first cam 110 is an annular structure, the first magnetic component 142 can be set on the protrusion 112, or set on the annular structure at a position opposite to the protrusion 112, or set at other positions on the end face, the first end face is an annular structure, the second magnetic component 144 can be set on the guide part 124, or set at the starting position of the damping part 122, or set on the annular structure at a position opposite to the starting position of the damping part 122.

[0058] Specifically, the first magnetic member 142 may be buried in the first cam 110, embedded in the first cam 110, or disposed on the surface of the first cam 110, and the second magnetic member 144 may be buried in the second cam 120, embedded in the second cam 120, or disposed on the surface of the second cam 120. The first magnetic member 142 and the second magnetic member 144 may have N poles facing each other, or S poles facing each other, and the number of the first magnetic member 142 may be one or more, the number of the second magnetic member 144 may be one or more, and the number of the first magnetic member 142 and the second magnetic member 144 may be the same or different.

[0059] like Figure 8 As shown, as a possible implementation, it also includes: a rotating shaft 150 , the first cam 110 and the second cam 120 are sleeved on the rotating shaft 150 , and the damping part 122 and the guide part 124 are arranged on the annular end surface of the second cam 120 .

[0060] Specifically, the first cam 110 and the second cam 120 are sleeved on the outside of the rotating shaft 150, so that the relative surfaces of the first cam 110 and the second cam 120 are annular structures, and the damping part 122 and the guide part 124 form an annular end face, thereby reducing the circumferential size of the first cam 110 and the second cam 120, and when the first cam 110 and the second cam 120 rotate, a continuous motion state can be formed.

[0061] Furthermore, the rotating shaft 150 can be used to limit the rotation direction of the first cam 110 and the second cam 120, thereby saving space.

[0062] As a possible implementation manner, when the protrusion 112 moves from one end of the damping portion 122 to the other end of the damping portion 122 , the relative rotation angle between the first cam 110 and the second cam 120 is less than or equal to 30 degrees.

[0063] Specifically, during the entire process of the protrusion 112 moving from one end of the damping portion 122 to the other end of the damping portion 122, the first cam 110 rotates as a whole by A degree, and A degree is less than or equal to 30 degrees, thereby reducing the angle of the work rotation of the first cam 110 and reducing the work done by rotating the first cam 110, making it easier to use the opening device 330 to control the rotation of the first cam 110. For example, the magnetic drive is limited by distance, so reducing the value range of A degree can make it easier to drive the automatic rotation of the first cam 110.

[0064] Among them, the value of A degree can be 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees or 30 degrees.

[0065] like Figure 4As shown, as a possible implementation, the damping portion 122 includes an ascending surface; the guiding portion 124 includes a descending surface, and the protrusion 112 automatically rotates when in contact with the guiding portion 124 .

[0066] Specifically, the damping part 122 includes an ascending surface, and the guide surface includes a descending surface. The ascending surface and the descending surface are connected in sequence to form an annular structure, and the damping of the damping part 122 is provided by the elastic member 130. The first cam 110 and the second cam 120 can adopt an integrated structure without changing the local material or surface roughness, etc., so that the hinge structure 100 has a simple structure and is easy to produce.

[0067] Specifically, one side of the protrusion 112 can fit with the damping portion 122, thereby improving the stability of the first cam 110 and the second cam 120, and then the first cam 110 and the second cam 120 can completely fit under the action of the elastic member 130 to achieve seamless connection.

[0068] The damping part 122 also includes a plane, that is, the damping part 122 can be a combination of a plane and a rising surface, that is, when the protrusion 112 moves onto the plane, the user is also required to do work on the first cam 110 and the second cam 120 .

[0069] like Figure 8 As shown, as a possible implementation, the hinge structure 100 includes a plurality of first cams 110 , a plurality of second cams 120 and a plurality of elastic members 130 .

[0070] Specifically, the hinge structure 100 includes multiple first cams 110, multiple second cams 120 and multiple elastic members 130, thereby sharing the force required for the electronic device 300 to rotate, reducing the possibility of the electronic device 300 being damaged due to excessive local force. The multiple first cams 110, multiple second cams 120 and multiple elastic members 130 can be arranged on a rotating shaft 150.

[0071] Specifically, the hinge structure 100 may include two first cams 110 , two second cams 120 , and two elastic members 130 , or three, four, five, or the like.

[0072] like Figure 8 As shown, the present application provides a hinge assembly 200, comprising: two hinge structures 100 as provided in the embodiment, multiple hinge structures 100 are arranged side by side, and in the two hinge structures 100, the directions of automatic rotation of the first cam 110 and the second cam 120 are opposite, and the two first cams 110 or the two second cams 120 of the two hinge structures 100 are connected.

[0073] The hinge assembly 200 provided in the present application includes two hinge structures 100 arranged side by side, the first cam 110 and the second cam 120 of one of the two hinge structures 100 automatically rotate to the left, and the first cam 110 and the second cam 120 of the other hinge structure 100 automatically rotate to the right, and the two first cams 110 or the two second cams 120 of the two hinge structures 100 are connected, so that the rotation width can be increased. When the hinge assembly 200 is applied to an electronic device 300, the distance between the first body 310 and the second body 320 in the electronic device 300 can be increased, so as to facilitate the bending of the electronic device 300, for example: an electronic device 300 with a flexible screen, and then the hinge assembly 200 includes two hinge structures 100, which can reduce the bending angle of the flexible screen and reduce the wind direction in which the flexible screen is damaged due to folding.

[0074] Since the relative rotation angle of the first cam 110 and the second cam 120 of each of the two hinge structures 100 is 90 degrees, the number of the protrusions 112, the damping parts 122 and the guide parts 124 can be set to one group, two groups, three groups or four groups, etc., as long as the protrusions 112 only pass through the damping parts 122 in sequence when the first body 310 and the second component of the electronic device 300 are switched from the folded state to the unfolded state. That is, the first cams 110 or the second cams 120 of the two hinge structures 100 rotate 180 degrees relative to each other.

[0075] like Figure 8 As shown, as a possible implementation, it also includes: a linkage component 210, which is arranged on the two hinge structures 100 and is used to make the two first cams 110 or the two second cams 120 linked.

[0076] Specifically, the linkage assembly 210 can be used to realize the linkage of the two hinge structures 100, and then when the hinge assembly 200 opens and closes, the two first cams 110 or the two second cams 120 are linked, so that the movement of the entire hinge assembly 200 can be more unified, that is, the first cams 110 of the two hinge structures 100 enter the automatic rotation state at the same time, and then when the hinge assembly 200 is applied to the electronic device 300, the electronic device 300 can be automatically fully unfolded.

[0077] The linkage assembly 210 may be a gear set, and the rotating shaft 150 may be disposed through the gear set, so that the hinge assembly 200 forms a whole. Different gears on the gear set are respectively connected to the first cam 110 or the second cam 120 in the two hinge structures 100.

[0078] like Figure 8 As shown, as a possible implementation, it further includes: a bracket 220 , and the two hinge structures 100 are installed on the bracket 220 .

[0079] Specifically, two hinge structures 100 are installed on the bracket 220 , thereby improving the aesthetic appearance of the hinge assembly 200 , and making the entire hinge form an integral structure to achieve modularization of components. The linkage assembly 210 is located at both ends of the bracket 220 .

[0080] like Figure 8 As shown, as a possible implementation, it also includes: a first connecting member 232 connected to a first cam 110 of a hinge structure 100.

[0081] Specifically, the first connection portion is used to be connected to an external component.

[0082] like Figure 8 As shown, as a possible implementation, it also includes: a second connecting member 234 connected to the first cam 110 of another hinge structure 100.

[0083] Specifically, the second connection portion is used to be connected to an external component.

[0084] The first connection portion and the second connection portion may be connected to the first body 310 and the second body 320 of the electronic device 300 respectively.

[0085] like Fig. 9 As shown, during the opening process of the hinge assembly 200, the two hinge structures 100 pass through the first state, the second state and the third state.

[0086] In the first state, the two hinge structures 100 remain in a closed state. In the second state, the first cams 110 of the two hinge structures 100 rotate to both sides respectively and enter an automatic rotation state. In the third state, the two hinge structures 100 are fully opened.

[0087] like Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, the present application provides an electronic device 300, including: a first body 310 and a second body 320; a hinge structure 100 as provided in any of the above embodiments or a hinge assembly 200 as provided in any of the above embodiments, the first body 310 and the second body 320 are switched between an unfolded state and a folded state through the hinge structure or the hinge assembly 200.

[0088] Specifically, when the first body 310 and the second body 320 of the electronic device 300 are connected through the hinge structure 100 , the first body 310 and the second body 320 are connected to the first cam 110 and the second cam 120 , respectively.

[0089] When the first body 310 and the second body 320 of the electronic device 300 are connected through the hinge assembly 200 , the first body 310 and the second body 320 are connected to two first bodies 310 or two second bodies 320 , respectively.

[0090] The electronic device 300 provided in the present application includes the hinge structure 100 provided in any of the above embodiments or the hinge assembly 200 provided in any of the above embodiments, and therefore has all the beneficial effects of the hinge structure 100 provided in any of the above embodiments or the hinge assembly 200 provided in any of the above embodiments, which are not listed one by one here.

[0091] like Fig.10 , Fig.11 and Fig.13 As shown, as a possible implementation, it also includes: an opening device 330, which is provided on the first body 310 and the second body 320, and is used to drive the first body 310 and the second body 320 to transition from a folded state to an unfolded state, and to make the first cam 110 or the second cam 120 in the hinge structure 100 or the hinge assembly 200 enter an automatic rotation state.

[0092] Specifically, the electronic device 300 also includes an opening device 330, which can drive the first body 310 and the second body 320 to move, so that the first cam 110 in the hinge structure 100 or the hinge assembly 200 rotates greater than or equal to A degrees, and then, only the opening device 330 needs to be started, and the first body 310 and the second body 320 will automatically rotate, so that the first cam 110 in the hinge structure 100 or the hinge assembly 200 rotates greater than or equal to A degrees, so that the protrusion 112 disengages from the damping part 122 and adapts to the guide part 124, so that the first cam 110 and the second cam 120 can automatically rotate under the action of the elastic member 130, and then the entire unfolding process of the electronic device 300 does not require the user to do work, and only the opening device 330 and the elastic member 130 need to do work.

[0093] Specifically, the opening device 330 includes a third magnetic part 332 and an electromagnetic part 334, which are respectively arranged on the first body 310 and the second body 320, so that the state between the first body 310 and the second body 320 can be adjusted by controlling the current direction and current size of the electromagnetic part 334.

[0094] For example: Fig.10 and Fig.11As shown, when the first body 310 and the second body 320 are in the folded state, by adjusting the direction of the current, the electromagnetic member 334 and the third magnetic member 332 are in the same magnetic pole position relative to each other, and then the electromagnetic member 334 and the third magnetic member 332 generate a repulsive force, so that the first body 310 and the second body 320 move to the unfolded state, as shown in FIG. Fig.12 As shown, when the first body 310 rotates until the first cam 110 rotates to an angle of A, the first cam 110 and the second cam 120 enter an automatic rotation state, thereby achieving full expansion of the first body 310 and the second body 320.

[0095] like Fig.10 and Fig.11 As shown, when the first body 310 and the second body 320 are in a folded state, by adjusting the direction of the current, the electromagnetic component 334 and the third magnetic component 332 have opposite magnetic poles, and then the electromagnetic component 334 and the third magnetic component 332 generate suction, thereby improving the reliability of the first body 310 and the second body 320 in the folded state.

[0096] like Fig.13 As shown, when the first body 310 and the second body 320 are in the unfolded state or moving from the unfolded state to the folded state, by adjusting the direction of the current, the electromagnetic component 334 and the third magnetic component 332 are made to have opposite magnetic poles, and then the electromagnetic component 334 and the third magnetic component 332 generate suction, so that the first body 310 and the second body 320 can automatically move to the folded state at a certain angle.

[0097] The third magnetic member 332 may be a permanent magnet or an electromagnet.

[0098] The trigger switch of the opening device 330 may be a volume key or a power key, that is, the current direction and / or current magnitude of the electromagnetic component 334 may be controlled by the volume key or the power key.

[0099] Alternatively, the opening device 330 may be an elastic switch, and when the elastic switch is turned on, the first body 310 and the second body 320 rotate under the action of elastic force, thereby triggering the automatic rotation of the first cam 110 and the second cam 120 .

[0100] Specifically, the electronic device 300 includes a mobile phone, a laptop computer, a tablet computer or a wearable device.
