Detailed Description
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1 to 8, an embodiment of the invention discloses a rotating shaft assembly 1, which is disposed between a first main body 2 and a second main body 3 of an electronic device to realize a rotating connection therebetween. The rotary shaft assembly 1 includes a first rotary shaft 10, a second rotary shaft 20, and a force application structure 30. The first shaft 10 is configured to be axially movably connected to the first body 2. The second shaft 20 is configured to be fixedly coupled to the second body 3. The first rotating shaft 10 and the second rotating shaft 20 are coaxially arranged and are abutted in the axial direction, one of two opposite end walls 11 and 21 of the first rotating shaft 10 and the second rotating shaft 20 is provided with at least one convex part 12, and the other is provided with at least one groove 22 matched with the convex part 12. The biasing structure 30 acts on the first rotating shaft 10 to keep the first rotating shaft 10 and the second rotating shaft 20 in contact with each other at all times. The relative rotation of the first rotating shaft 10 and the second rotating shaft 20 can make the convex part 12 slide out of and into the groove 22, when the convex part 12 slides out of the groove 22, the first rotating shaft 10 generates axial movement and increases the potential energy of the force application structure 30, and the potential energy of the force application structure 30 makes the first rotating shaft 10 have the tendency of resetting in the axial direction.
When the first rotating shaft 10 and the second rotating shaft 20 rotate relatively, the convex part 12 can slide out of and into the groove 22, so that when the electronic device with the rotating shaft assembly 1 is in a certain open state, the positioning can be realized by the clamping of the convex part 12 and the groove 22, and the situation that the electronic device shakes due to slight force is avoided. Moreover, the force application structure 30 acts on the first rotating shaft 10 to keep the first rotating shaft in contact with the second rotating shaft 20, which is beneficial to reducing the attenuation of the torsion and prolonging the service life of the rotating shaft assembly 1.
Referring to fig. 3 to 6, in some embodiments, a plurality of grooves 22 are circumferentially distributed on the other of the two opposite end walls 11 and 21 of the first rotating shaft 10 and the second rotating shaft 20. When the first rotating shaft 10 and the second rotating shaft 20 rotate relatively, each of the at least one convex portion 12 can slide between at least two adjacent grooves 22, that is, when the first rotating shaft 10 and the second rotating shaft 20 rotate relatively, the convex portion 12 can slide out from one groove 22 to the corresponding end wall 21, the first rotating shaft 10 moves axially under the action of the convex portion 12 and increases the potential energy of the force application structure 30, as the relative rotation of the first rotating shaft 10 and the second rotating shaft 20 continues, the convex portion 12 can slide into the next groove 22 from the end wall 21 due to the tendency of the force application structure 30 to restore the first rotating shaft 10 in the axial direction, and when the first rotating shaft 10 and the second rotating shaft 20 rotate relatively in opposite directions, the convex portion 12 reversely performs the actions of sliding out and sliding into the groove 22 in cooperation with the force application structure 30.
Since each of the convex portions 12 is slidable between at least two adjacent concave grooves 22, the electronic device can be positioned at different opening angles (which may include zero degrees) when the hinge assembly 1 is assembled to the electronic device. In the case that the protrusion 12 can slide between the plurality of grooves 22, it is advantageous to solve the problem of the electronic device being covered or opened rapidly, and it is also possible to position the electronic device at a more opened angle.
It should be noted that the number of the projections 12 may be one or more than one. In the present invention, the number of the concave grooves 22 is not limited to a plurality of ones, and it is not excluded that only one or two concave grooves 22 are provided, as long as positioning in at least one state can be achieved by cooperation of the convex portion 12 and the concave groove 22.
Further, referring to fig. 3 to 6, the number of the protrusions 12 is at least two and is equally distributed along the circumferential direction of one of the two opposite end walls 11, 21 of the first rotating shaft 10 and the second rotating shaft 20; the plurality of grooves 22 are circumferentially equally spaced along the other of the facing end walls 11, 21 of the first and second shafts 10, 20. Because the convex parts 12 and the grooves 22 are circumferentially and equidistantly distributed, the first rotating shaft 10 and the second rotating shaft 20 can be always stressed in a balanced manner, and stable relative rotation and stable positioning between the first rotating shaft 10 and the second rotating shaft 20 can be further realized. When the number of the convex portions 12 is two and the convex portions 12 are circumferentially and equidistantly distributed, that is, when the two convex portions 12 are oppositely arranged, the opposite ends of the two convex portions 12 may be connected into a whole, and at this time, the convex portions 12 may also be regarded as one convex portion 12, correspondingly, the plurality of grooves 22 form at least two sets of two pairs of opposite grooves 22, the opposite ends of the two opposite grooves 22 of each set are communicated, and at this time, the grooves 22 may also be regarded as one groove 22 to be matched with the corresponding convex portion 12 (as shown in fig. 6 b).
Of course, the circumferentially equidistant distribution of the protrusions 12 and the grooves 22 is only an optional implementation manner, the arrangement of the protrusions 12 and the grooves 22 is not limited to this, the protrusions 12 and/or the grooves 22 may not be circumferentially equidistant distribution, the number of the protrusions 12 and the grooves 22 is not limited, and the positioning in at least one state can be realized by the cooperation of the protrusions 12 and the grooves 22.
Referring to fig. 4 and 5, in some embodiments, the end wall 11 of the first shaft 10 is provided with a protrusion 12, and the end wall 21 of the second shaft 20 is provided with a groove 22. Of course, in other embodiments, the end wall 11 of the first rotating shaft 10 may be provided with the groove 22, and the end wall 21 of the second rotating shaft 20 may be provided with the protrusion 12. The invention is not limited in this regard.
Referring to fig. 3, 4, 7 and 8, in some embodiments, the rotating shaft assembly 1 further includes a connecting sleeve 40, and the connecting sleeve 40 is configured to be fixedly connected to the first body 2; the first rotating shaft 10 is coaxially and slidably arranged in the connecting sleeve 40, a connecting structure allowing the first rotating shaft 10 to axially slide is arranged between the connecting sleeve 40 and the first rotating shaft 10, and the connecting structure drives the first rotating shaft 10 to rotate when the connecting sleeve 40 rotates. The arrangement of the connecting sleeve 40 can limit the first rotating shaft 10 to slide in the axial direction, the arrangement of the connecting structure enables the connecting sleeve 40 to drive the first rotating shaft 10 to rotate when rotating, and meanwhile, the connecting structure can not limit the axial reciprocating sliding of the first rotating shaft 10 in a certain range, so that the actions of sliding the convex part 12 out of and into the groove 22 can be realized when the first rotating shaft 10 and the second rotating shaft 20 rotate relatively.
Of course, the way of connecting the connecting sleeve 40 with the first main body 2 and using the connecting sleeve 40 and the connecting structure to drive the first rotating shaft 10 to rotate and allow the first rotating shaft 10 to axially reciprocate during the rotation process is only an optional implementation way, and the invention is not limited thereto. Any implementation manner that can be thought of by those skilled in the art may be implemented as long as the first rotating shaft 10 can be driven to rotate when the first main body 2 rotates, and at the same time, the axial reciprocating movement of the first rotating shaft 10 within a certain range is not limited, so that the convex portion 12 can slide out of and into the groove 22.
Further, the connecting sleeve 40 is fixedly connected with the first support 50, the first support 50 is fixedly installed on the first main body 2, and the first main body 2 is driven by the first support 50 to rotate conveniently. Second pivot 20 and second support 60 fixed connection, second support 60 fixed mounting borrow the connection of second support 60 in second main part 3, are convenient for realize the drive to second pivot 20 when second main part 3 rotates. Specifically, the first bracket 50 may be fixedly mounted to the first body 2 by screws or the like, and the second bracket 60 may be fixedly mounted to the second body 3 by screws or the like.
Further, a moving groove 13 is formed in the side wall of the first rotating shaft 10; the connecting structure comprises a locking member 70 fixedly connected with the connecting sleeve 40, the locking member 70 penetrates through the side wall of the connecting sleeve 40 and extends into the moving groove 13, and the locking member 70 can perform axial relative movement along the moving groove 13; when the connecting sleeve 40 rotates, the locking member 70 drives the first rotating shaft 10 to rotate. By means of the arrangement of the locking member 70, after the first rotating shaft 10 is installed into the connecting sleeve 40, the locking member 70 can penetrate through the outer side of the connecting sleeve 40, so that the connection between the first rotating shaft 10 and the connecting sleeve 40 is realized; in addition, since the moving groove 13 allows the locking member 70 to perform axial relative movement along the moving groove, the locking member 70 does not prevent the first rotating shaft 10 from axially reciprocating due to force during the rotation of the first rotating shaft 10 with the connecting sleeve 40, so that the protrusion 12 can slide out of and into the groove 22.
Of course, the connection structure is not limited to the manner of using the locking member 70, and accordingly, the first rotating shaft 10 is not limited to having the moving groove 13. As long as the connection between the first rotating shaft 10 and the connecting sleeve 40 can be realized so as to drive the first rotating shaft 10 to rotate by the connecting sleeve 40, and at the same time, the axial reciprocating movement of the first rotating shaft 10 in a certain range is not limited, so that the convex portion 12 can slide out of and into the groove 22, the connection structure may also adopt other various manners as will occur to those skilled in the art.
Further, the moving groove 13 penetrates the first rotating shaft 10; one end of the locking member 70 passes through the moving groove 13 and is fixedly coupled to the connection sleeve 40. Since the locking member 70 can pass through the first rotating shaft 10 and both ends of the locking member 70 are respectively connected to the connecting sleeve 40, the stable arrangement of the locking member 70 and the stability of the locking member 70 in cooperation with the first rotating shaft 10 can be ensured.
In a specific example, the locking member 70 is a pin, but is not limited thereto.
Further, the force application structure 30 is disposed in the connection sleeve 40 and acts on an end wall of the first rotation shaft 10 away from the second rotation shaft 20. It is understood that the force application structure 30 is not necessarily disposed in the connection sleeve 40, as long as a force can be always applied to the first rotating shaft 10 so that the first rotating shaft 10 and the second rotating shaft 20 always keep abutting.
Further, one end of the connecting sleeve 40 away from the second rotating shaft 20 is provided with a connecting portion 41, and the force application structure 30 is disposed between the connecting portion 41 and one end wall 14 of the first rotating shaft 10 away from the second rotating shaft 20. The installation of the force application structure 30 is facilitated by the installation of the connection portion 41. Of course, the manner in which the force application structure 30 is disposed within the connection sleeve 40 is not limited thereto.
In the example shown in fig. 3 and 4, the connection portion 41 is an end wall of the connection sleeve 40 itself, but is not limited thereto. The connecting portion 41 may be integrally formed with the connecting sleeve 40 (which may be, but is not limited to, an end wall of the connecting sleeve 40), or may be fixedly disposed on the connecting sleeve 40, and the specific configuration of the connecting portion 41 is not limited as long as the force application structure 30 can be disposed.
Specifically, the force application structure 30 includes an elastic member 31, and the elastic member 31 abuts between the connecting portion 41 and an end wall 14 of the first rotating shaft 10 away from the second rotating shaft 20; when the first rotating shaft 10 moves towards the connecting portion 41, the elastic member 31 is compressed to increase its elastic potential, and the elastic potential of the elastic member 31 makes the first rotating shaft 10 have a tendency to move towards the second rotating shaft 20. The elastic member 31 is used as the biasing structure 30 and is in contact with the connection portion 41 and the first rotating shaft 10, and the first rotating shaft 10 can be reliably reciprocated in the axial direction by repeated compression and rebound of the elastic member 31, so that the movement of sliding out the convex portion 12 and sliding into the concave groove 22 can be reliably realized when the first rotating shaft 10 and the second rotating shaft 20 relatively rotate, and the engagement effect of the convex portion 12 and the concave groove 22 can be ensured.
More specifically, the elastic member 31 may be, but is not limited to, a spring, and may also be an elastic structure having other spring-like functions.
It should be noted that the elastic member 31 is not limited to be directly abutted between the connecting portion 41 and the end wall 14 of the first rotating shaft 10 away from the second rotating shaft 20, and may be indirectly disposed between the connecting portion 41 and the end wall 14 of the first rotating shaft 10 away from the second rotating shaft 20, or may be disposed in another manner, as long as it can play a role of providing the elastic force to the first rotating shaft 10.
It should be noted that the force application structure 30 is not limited to the elastic member 31, for example, the force application structure may further include a magnetic structure (as shown in fig. 9), the magnetic structure may include a first magnetic member 32 disposed on the first rotating shaft 10 and a second magnetic member 33 disposed on the connecting sleeve 40, the second magnetic member 33 and the first magnetic member 32 repel each other, when the protruding portion 12 slides out of the groove 22, the axial movement of the first rotating shaft 10 makes the first magnetic member 32 approach the second magnetic member 33, so that the repulsive force of the second magnetic member 33 on the first magnetic member 32 is increased, and the first rotating shaft 10 may be pushed to reset as the first rotating shaft 10 and the second rotating shaft 20 continue to rotate relatively, so that the protruding portion 12 slides into the groove 22 again, and the positioning of the first rotating shaft 10 and the second rotating shaft 20 is achieved. Specifically, the first magnetic member 31 and the second magnetic member 32 may be respectively disposed on an end wall 14 of the first rotating shaft 10 away from the second rotating shaft 20 and the connecting portion 41, but are not limited thereto, as long as the first rotating shaft 10 can be always provided with a force toward the second rotating shaft 20.
Referring to fig. 3 and 4, in some embodiments, the first shaft 10 and the force application structure 30 are respectively disposed on two axial sides of the second shaft 20. Both end walls 21 of the second rotating shaft 20 are provided with one of the convex portions 12 and the concave grooves 22, and the corresponding end walls 11 of the first rotating shafts 10 are provided with the other of the convex portions 12 and the concave grooves 22, respectively. That is, both end walls 21 of the second rotating shaft 20 may be simultaneously provided with the protrusions 12, and correspondingly, the corresponding end walls 11 of both the first rotating shafts 10 are provided with the grooves 22; or both end walls 21 of the second rotating shaft 20 may be provided with grooves 22, and correspondingly, the corresponding end walls 11 of both the first rotating shafts 10 are provided with protrusions 12; or one of the two end walls 21 of the second rotating shaft 20 is provided with a protrusion 12 and the other is provided with a groove 22, and correspondingly, one of the corresponding end walls 11 of the two first rotating shafts 10 is provided with a groove 22 and the other is provided with a protrusion 12.
Because the second rotating shaft 20 can not move in the axial direction, the first rotating shaft 10 and the force application structure 30 can be respectively arranged on two axial sides of the second rotating shaft 20 to be matched with the second rotating shaft, so that the electronic equipment can be opened and closed by matching one second rotating shaft 20 with two first rotating shafts 10, the two second rotating shafts 20 do not need to be matched with one first rotating shaft 10, and meanwhile, the electronic equipment can be turned over always within a safe angle, and the service life of the electronic equipment is prolonged. It will be appreciated that this is only an alternative implementation of the invention.
Referring to fig. 1 to 8, an embodiment of the present invention further discloses an electronic device, which includes a first body 2 and a second body 3, wherein a rotating shaft assembly 1 is disposed between the first body 2 and the second body 3, and the rotating shaft assembly 1 is as described in the foregoing embodiments. By means of the arrangement of the rotating shaft assembly 1, the first main body 2 and the second main body 3 can be connected in a rotating mode, when the first main body 2 and the second main body 3 are in a certain opening state, the positioning can be achieved by the aid of the clamping of the convex portions 12 and the grooves 22, and the situation that the electronic equipment shakes due to slight force is avoided. In addition, the force application structure 30 acts on the first rotating shaft 10 to keep the first rotating shaft in contact with the second rotating shaft 20, which is beneficial to reducing the attenuation of the torsion and prolonging the service life of the rotating shaft assembly 1. In addition, when the convex portion 12 can slide between the plurality of concave grooves 22, in addition to positioning the electronic device in a plurality of states, the technical problem that the electronic device is easily and rapidly closed and opened can be solved. Preferably, the convex portion 12 can be engaged with the corresponding concave groove 22 when the electronic device is in the closed state and in a plurality of open states, so as to realize the positioning of the electronic device.
The electronic device may be, but is not limited to, a notebook computer, and when the electronic device is a notebook computer, the first body 2 is one of a system side and a screen side, and the second body 3 is the other of the system side and the screen side. In the example shown in the drawings, the first body 2 is a screen end, and the second body 3 is a system end, but the invention should not be limited thereto.
In the specific example shown in fig. 2, a positioning sleeve T is provided on the second body 3, and the connecting sleeve 40 is inserted into the positioning sleeve T to fix the position. Of course, the invention is not limited to this specific embodiment.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention is not limited by the appended claims.
