Detailed Description

Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood that the description is illustrative only and is not intended to limit the scope of the present disclosure. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present disclosure.

The words "a", "an" and "the" and the like as used herein are also intended to include the meanings of "a plurality" and "the" unless the context clearly dictates otherwise. Furthermore, the terms "comprises," "comprising," and the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.

All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It is noted that the terms used herein should be interpreted as having a meaning that is consistent with the context of this specification and should not be interpreted in an idealized or overly formal sense.

An embodiment of the present disclosure provides an electronic device including a first body, a second body, and a hinge through which the first body and the second body are connected. The hinge comprises a rotating shaft, a rotating shaft fixing structure integrated with the rotating shaft, a shaft sleeve matched with the surface of the rotating shaft, a shaft sleeve fixing structure integrated with the shaft sleeve and a buffer structure. The rotating shaft is fixed on the first body through the rotating shaft fixing structure. The shaft sleeve is fixed on the second body through the shaft sleeve fixing structure. The shaft sleeve is sleeved on the rotating shaft and can rotate relative to the rotating shaft. The buffer structure is used for starting to contact with the shaft sleeve when the shaft sleeve rotates to a preset angle relative to the rotating shaft from a preset initial position so as to buffer the current rotating speed of the shaft sleeve relative to the rotating shaft.

The electronic equipment provided by the embodiment of the disclosure can prevent mechanical structure damage caused by too high speed and too large force when a user rotates the first body and the second body of the electronic equipment to a certain extent, for example, a screw column for fixing a rotating shaft in an electronic equipment host with a sunken rotating shaft is broken, so that the electronic equipment is protected, and the reliability and the service life of the electronic equipment are improved.

Meanwhile, according to the electronic device provided by the embodiment of the disclosure, since the impact force generated when the first body and the second body of the electronic device rotate to the maximum angle is effectively reduced by the buffer structure, the strength of the system structure required for fixing the rotating shaft can be reduced, for example, the strength of the rotating shaft fixing structure, the strength of a screw column connected with the rotating shaft fixing structure, the strength of the first body connected with the rotating shaft fixing structure, and the like can be reduced. Furthermore, the above-mentioned structural strength of the electronic device can be reduced by reducing the corresponding structural size (for example, reducing the thickness), even if the electronic device reduces the structural space required for fixing the rotating shaft, or even can reduce a part of the reinforcing structure.

Fig. 1A and 1B schematically show an outline structure of an electronic apparatus according to an embodiment of the present disclosure.

As shown in fig. 1A and 1B, the electronic device 10 includes a first body 100, a second body 200, and a hinge 300, and the first body 100 and the second body 200 are connected by the hinge 300.

The hinge 300 includes a rotation shaft, a rotation shaft fixing structure integrated with the rotation shaft, a shaft sleeve matched with the surface of the rotation shaft, a shaft sleeve fixing structure integrated with the shaft sleeve, and a buffer structure.

The rotating shaft is fixed on the first body 100 through the rotating shaft fixing structure.

The sleeve is fixed on the second body 200 by the sleeve fixing structure.

The shaft sleeve is sleeved on the rotating shaft and can rotate relative to the rotating shaft.

The buffer structure is used for starting to contact with the shaft sleeve when the shaft sleeve rotates to a preset angle relative to the rotating shaft from a preset initial position so as to buffer the current rotating speed of the shaft sleeve relative to the rotating shaft.

Specifically, the electronic device 10 may be a notebook computer, a learning machine, an electronic dictionary, a medical device, or any other electronic device that requires a hinge, and the disclosure is not limited thereto.

According to the embodiment of the present disclosure, the position of the buffer structure may be located on the rotating shaft fixing structure shown in fig. 2A to 4B, or located on the shaft sleeve fixing structure, or located at the connecting position of the rotating shaft and the shaft sleeve. As long as the buffering structure can buffer the current rotation speed of the shaft sleeve relative to the rotating shaft when the shaft sleeve rotates to a preset angle relative to the rotating shaft from a preset initial position, which is not specifically limited by the present disclosure. For example, the sleeve is sleeved on the rotating shaft, and meanwhile, the sleeve is provided with a gap which extends for a certain angle along the circumferential direction, and the buffer structure can be positioned on the rotating shaft at a position corresponding to the gap. Thus, after the shaft sleeve rotates at a certain position relative to the shaft, one end face of the gap is contacted with the buffer structure, so that the buffer structure can act on the shaft sleeve to buffer the current rotating speed of the shaft sleeve relative to the rotating shaft. Other arrangement modes of the buffer structure can be more, and the details are not repeated.

It should be further noted that, as shown in fig. 2A to fig. 4B, the buffering structure may use a spring damping element to achieve the buffering effect, or may use a magnetic damping element, a hydraulic damping element, a compressed air damping element, a rubber damping element, a pulse damping element, a viscous damping element, and the like, which is not specifically limited in this disclosure.

According to the embodiment of the present disclosure, after the relative rotation of the first body 100 and the second body 200 of the electronic device 10 causes the bushing on the hinge 300 to contact with the buffering structure, the buffering structure may slow down the speed of the bushing continuing to rotate relative to the rotating shaft, so as to slow down the current rotating speed of the bushing in the hinge 300 relative to the rotating shaft, and accordingly slow down the speed of the first body 100 and the second body 200 continuing to rotate relative to each other.

In this way, the electronic device 10 can prevent the mechanical structure from being damaged when the user rotates the first body 100 and the second body 200 of the electronic device 10 at too high speed and with too much force. When the user rotates the first body 100 and the second body 200 of the electronic device 10 too fast and the force is too large, the shaft sleeve comes into contact with the buffer structure when the first body 100 and the second body 200 rotate relatively to a certain degree, so that the buffer structure acts on the shaft sleeve to slow down the speed of the relative rotation of the first body 100 and the second body 200, and the user feels the resistance to the continuous rotation of the first body 100 and the second body 200, in this way, the user is prompted that the current relative angle of the first body 100 and the second body 200 is close to the maximum angle, so that the user stops rotating the first body 100 and the second body 200, or the user reduces the force of the continuous rotation.

According to the embodiment of the disclosure, the buffering result is arranged in the hinge of the electronic device 10, so that the reliability of the electronic device 10 is improved, the service life of the electronic device 10 is prolonged, the strength and space of a system structure required by the electronic device for fixing the rotating shaft are reduced, and even a corresponding reinforcing structure can be reduced. In this way, the cost of the electronic device 10 can be reduced, which is beneficial to the light and thin of the electronic device 10.

Fig. 2A to 4B schematically show structural state diagrams of a hinge of an electronic apparatus according to an embodiment of the present disclosure in different states.

As shown in fig. 2A to 4B, the hinge 300 includes a rotation shaft 310 and a rotation shaft fixing structure 320 integrated with the rotation shaft 310, a shaft sleeve 330 fitted to a surface of the rotation shaft 310 and a shaft sleeve fixing structure 340 integrated with the shaft sleeve 330, and a buffer structure 350.

The rotation shaft 310 is fixed to the first body 100 (not shown in fig. 2A to 4B) by a rotation shaft fixing structure 320.

The bushing 330 is fixed to the second body 200 (not shown in fig. 2A to 4B) by a bushing fixing structure 340.

The sleeve 330 is sleeved on the rotating shaft 310 and can rotate relative to the rotating shaft 310.

And a buffering structure 350 for beginning to contact the sleeve 330 when the sleeve 330 starts to rotate to a preset angle with respect to the rotation shaft 310 from a preset initial position to buffer the current rotation speed of the sleeve 330 with respect to the rotation shaft 310.

Specifically, fig. 2A schematically illustrates a structure view of the hinge 350 when the positions of the first body 100 and the second body 200 of the electronic device 10 according to the embodiment of the present disclosure are overlapped.

The sleeve fixing structure 340 coincides with a portion of the rotation shaft fixing structure 320 in fig. 2A, corresponding to a state in which the first body 100 and the second body 200 of the electronic device 10 are closed, i.e., the state of the electronic device 10 shown in fig. 1B. At this time, the sleeve 330 does not contact the buffer structure 350, which can be clearly seen from the partially enlarged view of the buffer structure in this state in fig. 2B.

Fig. 3A schematically illustrates a structure view of the hinge 350 when the second body 200 of the electronic device 10 rotates to a preset angle with respect to the first body 100 according to an embodiment of the present disclosure.

In fig. 3A, the shaft sleeve fixing structure 340 and the rotation shaft fixing structure 320 form an included angle, which corresponds to a state where the first body 100 and the second body 200 of the electronic device 10 are opened, i.e., the state of the electronic device 10 shown in fig. 1A.

Further, with respect to the state of the hinge 300 in fig. 2A and 2B, the sleeve fixing structure 340 and the rotation shaft fixing structure 320 in fig. 3A rotate relatively to each other by a predetermined angle. At this time, the buffer structure 350 comes into contact with the boss 330, which can be clearly seen from a partially enlarged view of the buffer structure in this state in fig. 3B.

Fig. 4A schematically illustrates a structure view of the hinge 350 when the second body 200 of the electronic device 10 rotates to a maximum angle with respect to the first body 100 according to an embodiment of the present disclosure.

The hinge 350 in fig. 4A is in a state that the angle between the sleeve fixing structure 340 and the rotation shaft fixing structure 320 is further increased to a maximum angle in the state of fig. 3A, and specifically, as can be seen from the enlarged view of the buffering structure in this state in fig. 4B, the buffering structure 350 has been moved to a maximum displacement, so that the sleeve 330 cannot rotate any more.

As shown in fig. 2A to 4B, according to an embodiment of the present disclosure, the buffer structure 350 is located on the rotating shaft fixing structure 320.

Specifically, when the first body 100 and the second body 200 relatively rotate, for example, a pushing force is applied to the second body 200 to rotate the second body 200, the sleeve fixing structure 340 fixed to the second body 200 rotates in synchronization with the second body 200, so that the sleeve 330 rotates relative to the rotating shaft 310 from a preset initial position. When rotated to a preset angle, the buffer structure 350 comes into contact with the sleeve 340 to buffer the current rotation speed of the sleeve 330 with respect to the rotation shaft 310 (as shown in fig. 3A-4B). In this way, the buffering structure 350 can prevent the mechanical structure of the electronic device 10 from being damaged due to the over-fast rotation speed and the over-large force of the first body 100 and the second body 200 to a certain extent, thereby improving the reliability and the lifespan of the electronic device 10, reducing the structural strength and the space of the system required for fixing the rotating shaft 310, reducing the reinforcing structure, reducing the cost, and facilitating the lightening and thinning of the electronic device 10.

As shown in fig. 2B, the buffer structure 350 includes a damping structure 351 and a stopper 352, wherein the damping structure 351 is embedded inside the rotating shaft fixing structure 320, and the stopper 352 is fixed at one end of the damping structure 351 and is higher than the surface of the rotating shaft fixing structure 320.

The side of the sleeve 330 near the buffer structure 350 includes a fan-shaped notch, and the angle of the fan-shaped notch is the predetermined angle.

The contact of the bumper 350 with the boss 330 includes the contact of the stopper 352 with the scalloped notch of the boss 330.

Specifically, when the sleeve 330 rotates relative to the rotating shaft 310 from a predetermined initial position, when the sleeve 330 rotates to a predetermined angle, one end of the fan-shaped notch of the sleeve 330 contacts the stopper 352, and if the sleeve 330 continues to rotate, the stopper 352 is pushed to move, so that the damping structure 351 is acted, and the damping structure 351 generates a certain reaction force. This reaction force causes the stop 352 to provide some resistance to the hub 330 to dampen the current rotational speed of the hub 330 relative to the shaft 310.

It should be noted that the predetermined angle is smaller than the maximum angle that the first body 100 and the second body 200 of the electronic device 10 can rotate, and the maximum angle is equal to the predetermined angle and the angle that the sleeve 330 can continue to rotate after beginning to contact the stop 352. For example, if the maximum angle at which the first body 100 and the second body 200 in the electronic device 10 can rotate relatively is 140 °, the preset angle may be 135 °, and the maximum angle at which the sleeve 330 can continue to rotate after it starts to contact the stopper 352 is 5 °. Thus, when the user rotates the first body 100 or the second body 200 of the electronic device 10, the user starts to feel a certain resistance when the relative angle between the two bodies is 135 °, but can continue to rotate. Thus, on the one hand, the user is prompted to stop rotating the first body 100 and the second body 200 of the electronic device 10 in time, and at the same time, if the speed of rotating the first body 100 or the second body 200 is too fast or too large before the user starts to feel the resistance, even if the user immediately stops applying the external force to the electronic device 10, the first body 100 and the second body 200 themselves continue to rotate relative to each other by a certain angle due to inertia, and thus, the relative angle when the first body 100 and the second body 200 finally stop rotating is naturally greater than 135 °. Accordingly, the reserved sleeve 330 can continue to rotate a certain angle after it comes into contact with the stopper 352, providing a space for such inertial movement between the first body 100 and the second body 200.

It should be noted that the predetermined angle can be determined by the size of the fan-shaped notch included in the sleeve 330 according to the actual requirements of the electronic device 10 during design and manufacture. For example, if the electronic device 10 is a notebook computer, and the maximum angle that the screen can be opened is 140 ° for the convenience of the user, if it is desired to start from 135 ° and prompt the user, the preset angle may be 135 °, that is, the angle of the fan-shaped notch included in the shaft sleeve 330 should be 135 °.

Fig. 2C schematically illustrates an exploded view of the cushioning structure of fig. 2B.

In conjunction with fig. 2C and 2B, damping structure 351 includes a groove 3511, a sliding element 3512, and a damping element 3513, in accordance with an embodiment of the present disclosure.

The groove 3511 includes a sliding rail groove and a damping buffer groove. Slide element 3512 includes a first portion located in the damping bumper channel and a second portion located in the sliding track channel. A damping member 3513 is positioned in the damping bumper in contact with the first portion of the slide member 3512.

Stop 352 is secured to a second portion of slide member 3512.

The slide member 3512 is movable along the slide rail groove with the stopper 352.

Specifically, when the sleeve 330 rotates to a predetermined angle with respect to the rotating shaft 310 from a predetermined initial position (e.g., the position shown in fig. 2A and 2B), one end of the scalloped gap of the sleeve 330 contacts the stopper 352 (as shown in fig. 3A and 3B).

If the sleeve 330 continues to rotate, the sleeve 330 will push the stop 352 forward. Since stop 352 is fixed to the second portion of slide 3512, slide 3512 is urged to move along the slide track groove in groove 3511 along with stop 352.

Upon movement of slide element 3512, damping dampening grooves in groove 3511 compress damping element 3513 in contact with the first portion of slide element 3512, thereby causing damping element 3513 to generate a counter force that resists movement.

This opposing force will create some resistance to the hub 330 by the stop 352. And the longer the sliding element 3512 travels in the sliding track groove in groove 3511, the more compression is applied to damping element 3513, such that the greater the reaction force generated by damping element 3513. Accordingly, the greater the resistance to the sleeve 330, the more effectively the current rotational speed of the sleeve 330 relative to the shaft 310 can be damped.

In accordance with an embodiment of the present disclosure, sliding element 3512 may be in an "" configuration, wherein the first portion includes a "chevron" configuration, the second portion includes a "|" configuration below the first portion, and damping element 3513 is fitted over a vertical leg in the middle of the "chevron".

According to the embodiment of the present disclosure, the damping buffer groove of the groove 3511 may further include a sliding groove with a narrower width at an end of the damping buffer groove far from the sliding member 3512. As the slide element 3512 moves along the slide track groove, the vertical leg, which houses the damping element 3513, is able to enter and move within the slide groove while compressing the damping element 3513. Therefore, the vertical branch can fix the damping element 3513, and can better determine the moving track of the sliding element 3512, so as to avoid the blocking of the buffer structure 350, and the like, so that the buffer structure 350 is more durable and reliable.

According to an embodiment of the present disclosure, the damping structure 351 further includes a rubber 3514, the rubber 3514 is located at an end of the damping buffer slot of the groove 3511 far from the sliding element 3512, so as to avoid hard collision with the damping buffer slot when the sliding element 3512 moves to the top end of the damping buffer slot.

Specifically, when the sleeve 330 rotates to a predetermined angle relative to the rotating shaft 310 from a predetermined initial position, one end of the fan-shaped notch of the sleeve 330 contacts the stopper 352 (as shown in fig. 3A and 3B). If the sleeve 330 continues to rotate, the sleeve 330 will push the stopper 352 to move forward, and since the stopper 352 is fixed on the sliding member 3512, the sliding member 3512 moves along the sliding track groove along with the stopper 352, and when the sliding member 3512 moves to the top of the damping buffer groove, it can not move forward until contacting the rubber 3514, and at the same time, the sleeve 330 can not rotate any more (as shown in fig. 4A and 4B). Due to the soft texture of the rubber 3514, the sliding element 3512 can be effectively prevented from hard collision with the damping buffer groove when moving to the top end of the damping buffer groove, so that abrasion among the elements can be avoided.

It should be noted that the damping element 3513 shown in fig. 2A to 4B is a spring only as an example. The damping element 3513 may also be any other damping element, such as a magnetic damping element, a rubber damping element, a pulse damping element, a viscous damping element, etc., as long as the damping element 3513 is capable of generating a counter force that resists movement of the sliding element 3512, which is not specifically limited by this disclosure.

According to an embodiment of the present disclosure, damping element 3513 comprises a hydraulic damping element.

According to an embodiment of the present disclosure, damping element 3513 comprises a rubber damping element.

According to an embodiment of the present disclosure, damping element 3513 comprises a compressed air damping element.

According to an embodiment of the present disclosure, the damping element 3513 comprises a spring damping element.

According to the electronic apparatus 10 of the embodiment of the present disclosure, when the first body 100 and the second body 200 of the electronic apparatus 10 are rotated, for example, an initial state is preset in which an angle between the first body 100 and the second body 200 is 0 °, that is, the second body 200 is completely folded to cover the first body 100, as shown in fig. 1B. The state of the hinge 300 at this time is as shown in fig. 2A, and the relationship of the boss 330 and the buffer structure is as shown in fig. 2B. At this time, one end of the fan-shaped notch of the sleeve 330 is not in contact with the stopper 352 of the buffer structure and is farthest away.

When the first body 100 and the second body 200 of the electronic device 10 are relatively rotated, the sleeve 330 fixed to the second body 200 is also rotated relative to the rotation shaft 310 from a predetermined initial position in synchronization. When the relative rotation angle reaches a predetermined angle, one end of the scalloped notch of the sleeve 330 contacts the stopper 352, as shown in fig. 3A and 3B.

At this time, even if the user immediately stops applying the external force to the electronic device 10 to rotate the first body 100 or the second body 200, the first body 100 and the second body 200 may continue to rotate relatively for a certain distance in consideration of a certain reaction time required by the user or a certain inertial motion of the first body 100 and the second body 200 themselves. Thus, the stopper 352 is correspondingly pushed to move synchronously, the movement of the stopper 352 drives the sliding element 3512 to move in the sliding track groove of the groove 3511, and the sliding element 3512 compresses the damping element 3513 in the damping buffer groove after moving, so that the damping element 3513 generates a reverse force for stopping the movement. Further, the longer the moving distance of the sliding member 3512 is, the larger the reverse force of the damping member 3513 against the movement is, and thus the larger the resistance force received by the sleeve 330 is, so that the rotation of the sleeve 330 with respect to the rotating shaft 310 can be rapidly reduced, thereby effectively performing a buffering function.

In this way, on one hand, the electronic device 10 can prevent the mechanical structure from being damaged due to too high speed and too large force when the user rotates the first body and the second body of the electronic device to a certain extent, and the reliability and the service life of the electronic device 10 are improved.

On the other hand, the impact force generated when the first body and the second body of the electronic device 10 rotate to the maximum angle is effectively reduced by the buffering structure, so that the electronic device 10 can also reduce the strength of the system structure required for fixing the rotating shaft, reduce the structural space required for fixing the rotating shaft 310, and even reduce a part of the reinforcing structure. Therefore, while ensuring the reliability of the electronic device 10, it is also beneficial to reduce the cost and the product is light and thin.
