All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
As shown in fig. 1 to 4, the present embodiment provides a hinge mechanism, which includes a first connecting plate 100, a second connecting plate 200 and a control assembly. The first connecting plate 100 is connected with a first rotating shaft 110; the second connecting plate 200 is connected with a second rotating shaft 210; the control component is used for controlling the first connecting plate 100 and the second connecting plate 200 to switch between the first relative position and the second relative position; the control component is rotatably connected with the first rotating shaft 110 and the second rotating shaft 210; the first connecting plate 100 and the second connecting plate 200 are located at a first relative position, the first connecting plate 100 and the second connecting plate 200 are folded relatively, a first surface of the first connecting plate 100 is arranged opposite to a first surface of the second connecting plate 200, and a first distance is formed between the first rotating shaft 110 and the second rotating shaft 210; the first connecting plate 100 and the second connecting plate 200 are located at a second relative position, the first connecting plate 100 and the second connecting plate 200 are unfolded relatively, and a second distance is formed between the first rotating shaft 110 and the second rotating shaft 210; the second pitch is greater than the first pitch.
According to the rotating shaft mechanism provided by the embodiment of the application, the control component controls the first connecting plate 100 and the second connecting plate 200 to switch between the first relative position and the second relative position, so that the distance between the first rotating shaft 110 connected with the first connecting plate 100 and the second rotating shaft 210 connected with the second connecting plate 200 is changed. The first connecting plate 100 and the second connecting plate 200 are located at a first relative position, the first connecting plate 100 and the second connecting plate 200 are folded relatively, and a first distance is formed between the first rotating shaft 110 and the second rotating shaft 210; the first connecting plate 100 and the second connecting plate are located at a second relative position, the first connecting plate 100 and the second connecting plate 200 are unfolded relatively, and a second distance is formed between the first rotating shaft 110 and the second rotating shaft 210. Since the second distance is greater than the first distance, during the operation from the first relative position (the first connection plate 100 and the second connection plate 200 are folded relatively) to the second relative position (the first connection plate 100 and the second connection plate 200 are unfolded relatively), the region of the first connection plate 100 connected to the first rotation shaft 110 and the region of the second connection plate 200 connected to the second rotation shaft 210 are away from each other, the movement paths of the first connection plate 100, the second connection plate 200 and the component (housing, etc.) connected to the first connection plate 100 or the second connection plate 200 during the rotation are prevented from interfering with each other, the surface of the component (including the first connection plate 100, the second connection plate 200 and the component connected to the first connection plate 100 or the second connection plate 200) is not required to be deformed, only the distance between the first rotation shaft 110 and the second rotation shaft 210 is required to be adjusted, a sufficient rotation space can be provided for the component, and the distance between the first connection plate 100 and the second connection plate 200 in the first relative position is ensured to be reduced (the first distance is smaller than the second distance).
The distance between the first rotating shaft 110 and the second rotating shaft 210 is adjustable, and the structure of the rotating shaft cover does not need to be changed, so that the appearance smoothness of the electronic equipment is realized, and the thinning design of the electronic equipment under the folding state is facilitated.
The hinge mechanism also enables the third position state of the first and second link plates 100 and 200 for convenience of use. That is, the control assembly is also used for controlling the first connecting plate 100 and the second connecting plate 200 to switch between the second relative position and the third relative position; the control component is rotatably connected with the first rotating shaft 110 and the second rotating shaft 210; the first connecting plate 100 and the second connecting plate 200 are located at a third relative position, the first connecting plate 100 and the second connecting plate 200 are folded relatively, the second surface of the first connecting plate 100 is arranged opposite to the second surface of the second connecting plate 200, and a third distance is formed between the first rotating shaft 110 and the second rotating shaft 210; the second pitch is greater than the third pitch.
The first surface and the second surface of the first connecting plate 100 are two surfaces on which the first connecting plate 100 is disposed, and the first surface and the second surface of the second connecting plate 200 are two surfaces on which the second connecting plate 200 is disposed. That is, the first connecting plate 100 and the second connecting plate 200 are located at the first relative position, so that the first surface of the first connecting plate 100 and the first surface of the second connecting plate 200 are located on the outer side surface of the integral rotating shaft mechanism; the first connecting plate 100 and the second connecting plate 200 are located at a second relative position, which realizes that the second surface of the first connecting plate 100 and the second surface of the second connecting plate 200 are located at the outer side surface of the integral rotating shaft mechanism. The user can adjust according to actual use requirements.
Preferably, the second distance is greater than the third distance, and as above, the surface of the component (including the first connecting plate 100, the second connecting plate 200 and the component connected to the first connecting plate 100 or the second connecting plate 200) does not need to be cut, and only the distance between the first rotating shaft 110 and the second rotating shaft 210 needs to be adjusted to provide a sufficient rotating space for the component, and the distance between the first connecting plate 100 and the second connecting plate 200 at the third relative position after being folded is reduced (the third distance is smaller than the second distance), so that the design of thinner thickness after being folded is realized.
In this embodiment, the first distance and the third distance may be the same, that is, when the first connecting plate 100 and the second connecting plate 200 are at the first relative position and at the third relative position, the gap formed between the first rotating shaft 110 and the second rotating shaft 210 is the same. Through the arrangement, the control assembly can be conveniently designed into an axisymmetric structure.
Of course, the first pitch and the third pitch may be different. The first distance may be greater than the second distance, that is, the distance between the first rotating shaft 110 and the second rotating shaft 210 when the first connecting plate 100 and the second connecting plate 200 are in the first relative position is greater than the distance between the first rotating shaft 110 and the second rotating shaft 210 when the first connecting plate 100 and the second connecting plate 200 are in the third relative position. Of course, the first distance may be smaller than the second distance, that is, the distance between the first rotating shaft 110 and the second rotating shaft 210 when the first connecting plate 100 and the second connecting plate 200 are at the first relative position is smaller than the distance between the first rotating shaft 110 and the second rotating shaft 210 when the first connecting plate 100 and the second connecting plate 200 are at the third relative position. Through the setting, can adjust corresponding structure according to actual design demand to in the concrete structure that sets up pivot mechanism according to the in-service use scene, improved the adaptation degree of pivot mechanism.
It should be noted that the first distance is only the distance between the first rotating shaft 110 and the second rotating shaft 210 when the first connecting plate 100 and the second connecting plate 200 are in the first relative position, and is not the total thickness of the relative folding when the first connecting plate 100 and the second connecting plate 200 are in the first relative position; the third distance is only the distance between the first rotating shaft 110 and the second rotating shaft 210 when the first connecting plate 100 and the second connecting plate 200 are in the third relative position, and is not the total thickness of the relative folding of the first connecting plate 100 and the second connecting plate 200 in the third relative position. The total thickness of the first connecting plate 100 and the second connecting plate 200 folded relatively depends on the position of the connecting plates (the first connecting plate 100 and the second connecting plate 200) where the rotating shafts (the first rotating shaft 110 and the second rotating shaft 210) are arranged and the specific structure of the connecting plates. Therefore, the position of the first rotating shaft 110 fixed on the first connecting plate 100 and the position of the second rotating shaft 210 fixed on the second connecting plate 200 can be adjusted according to actual requirements.
The control component comprises a supporting structure 300 and an intermediate transmission component connected with the first rotating shaft 110 and the second rotating shaft 210, the first rotating shaft 110 is rotatably connected with a first connecting position of the supporting structure 300, and the second rotating shaft 210 is slidably and rotatably connected with a second connecting position of the supporting structure 300; the intermediate transmission assembly controls the first rotating shaft 110 and the second rotating shaft 210 to rotate synchronously.
