Detailed Description
The technical solution of the present invention is further described in detail with reference to the drawings and the specific embodiments of the specification.
Fig. 1 to 4 are schematic structural diagrams of an electronic device, in which fig. 1 to 4 all show a hinge structure, and fig. 5 is a side view of a special hinge structure. As can be seen from the above illustration, the present embodiment provides a hinge structure, including:
a shaft core 110;
a drum 120 located at the periphery of the shaft 110 and capable of rotating relative to the shaft 110;
wherein, a sliding groove 130 for changing the position of the shaft center 110 is arranged in the rotating cylinder 120; the sliding groove 130 includes: a first end and a second end;
when the hub 110 is at the first end, the drum 120 is capable of rotating relative to the hub 110 from a first position to a second position;
when the hub 110 is at the second end, the drum 120 is capable of rotating relative to the hub 110 from the second position to a third position.
In this embodiment, the rotating shaft structure may be a rotating structure connecting two opposite portions. The single rotating shaft at least comprises: a hub 110 and a drum 120. In this embodiment, the shaft 110 and the drum 120 may be both one, so the rotating shaft structure provided in this embodiment may be a structure of a single rotating shaft.
In this embodiment, the hub 110 is located outside the drum 120, and the drum 120 is generally rotatable relative to the hub 110. The shaft 110 may be a solid shaft 110, or may be a hollow shaft with a hollow interior. In some implementations, the hub 110 can be a solid hub 110 in order to minimize the volume of the shaft structure and provide strength to the shaft structure. In some embodiments, the core 110 may be a solid core 110 made of a metal or alloy material having a density lower than a predetermined density threshold and a strength greater than a predetermined light weight, such as an aluminum alloy or the like.
The drum 120 may be a cylindrical structure provided with a hollow space for mounting the hub 110. That is, a hollow cavity is disposed in the drum 120, and the shaft 110 is located in the hollow cavity.
As shown in the figure, in the present embodiment, a sliding groove 130 for sliding the shaft center 110 is further disposed in the drum 120, and the sliding groove 130 is opened along the extending direction of the drum 120. When the position of the shaft 110 in the sliding groove 130 is changed, the rotational angle between the shaft 110 and the drum 120 is changed again.
The first end may be a position of one end point of the sliding groove 130, and the second end may be a position of the other end point of the sliding groove 130, when the shaft 110 is at the first end, the drum may rotate from the first position to the second position relative to the shaft 110, where the first position and the second position may be relative to other reference points, for example, ground, independent of the shaft 110 and the drum 120. If the hub 110 slides from the first end to the second end, the drum 120 may continue to rotate from the second position to the third position. The first position and the third position are different positions with respect to the reference point.
If it is assumed that the hub shown in fig. 1 and 2 is located at a first end, the hub shown in fig. 3 is located at a second end. Fig. 5 shows that one end of the sliding groove 130 is included in the center of the drum 120, whereas in fig. 1 to 4, the sliding groove 130 itself does not pass through the center of the drum 120.
If the center point of the rotating cylinder 120 is taken as the center point, the angle covered by the sliding groove 130 on the side surface of the rotating cylinder 120 may be not greater than 180 degrees, and may be 90 degrees or 145 degrees, and may be between 90 and 180 degrees in general, but is not limited to this in the specific implementation.
Generally, the rotation angle of the single shaft 110 and the drum 120 for the electronic device is 145 degrees, and does not exceed 180 degrees at most. In the present embodiment, the single shaft 110 and the drum are directly used, and the rotatable angle of the two parts connected to the shaft 110 and the drum 120 can be enlarged by providing the sliding groove 130 in the drum 120. Therefore, the device has the characteristics of simple structure, small volume and large rotatable range.
For example, the angle of rotation of the drum 120 from the first position to the second position is a first angle; the angle of rotation of the drum 120 from the second position to the third position is a second angle; the sum of the first angle and the second angle is greater than 180 degrees.
In some embodiments, the sum of the first and second angles may be 270 degrees, 225 degrees, or even 360 degrees.
In short, the rotation shaft structure provided by the embodiment can realize the rotation of a large rotation angle between two different parts connected to the shaft center 110 and the rotating drum 120, and has the characteristics of simple structure, small volume and high strength.
Optionally, when the hub 110 is at the first end, the drum 120 is capable of rotating in a first rotational direction relative to the hub 110 from a first position to a second position;
when the hub 110 is at the second end, the drum 120 is rotatable relative to the hub 110 in the first rotational direction from the second position to a third position.
The rotation direction in this embodiment may include: the drum 120 rotates in both a clockwise direction and a counterclockwise direction relative to the hub 110. In this embodiment, the first rotating direction may be the clockwise rotating direction, or the counterclockwise rotating direction.
In this embodiment, the first position to the second position is a first rotation direction, the second position to the third position is a continuous rotation along the original rotation direction, and if the second position is a limit position where the shaft center 110 is located at the first end, the rotating drum 120 can rotate relative to the shaft center 110, it is obvious that the shaft center 110 can rotate in the original rotation direction continuously by moving from the first end to the second end, and the rotating drum 120 can rotate from the second position to the third position, so that the expanded rotatable angle of the rotating drum 120 relative to the shaft center 110 has a large rotatable range.
The sliding groove 130 includes: a segment of arc-shaped groove.
As shown in fig. 1 to 3, the sliding groove 130 may be a one-segment arc-shaped groove; the arc-shaped groove is continuously and smoothly changed everywhere. In a one-piece arc slot, the shaft 110 moves smoothly.
Alternatively, as shown in fig. 4, the sliding groove 130 includes: at least two sections of communicated arc-shaped grooves;
and smooth separation bulges are arranged at the junction positions of the arc-shaped grooves at the two connected ends.
In this embodiment, the one-segment arc-shaped groove is provided, the sliding groove 130 provided therein is formed by connecting a plurality of segments of arc-shaped grooves, and a separation protrusion is provided between the segments, so that the separation protrusion applies a certain blocking force to the shaft center 110 at the separation protrusion of the sliding groove 130, and in this way, the shaft center 110 can stably stay at the separation protrusion of the two segments of arc-shaped grooves, so that a user can move the shaft center 110 to different segments of arc-shaped grooves as required, thereby controlling the rotatable angle of the rotating drum 120 relative to the shaft center 110.
In short, the separation protrusion is used to provide the supporting force required by the hub 110 at the interface position. The support force is sufficient to stabilize the hub 110 at the interface position.
In this embodiment, if the center point of the rotating drum 120 is taken as the center point, the sliding groove 130 covers the side surface of the rotating drum 120 at an angle, the sliding groove 130 is formed by a plurality of segments of arc-shaped grooves that are communicated, and the angle covered by the arc-shaped grooves on the side surface of the rotating drum may be any angle, for example, may be 90 degrees, 180 degrees, or even 270 degrees to 360 degrees. The total angle of coverage after the arc-shaped grooves of the multiple sections are communicated can be 360 degrees. In this way, the shaft 110 can slide to another position of the sliding groove 130 at any position of the person.
As shown in fig. 1 to 4, the present embodiment provides an electronic device including:
the first body portion 210 is formed in a first body portion,
the second body portion 220 is connected by a hinge structure provided in any one of the above-mentioned embodiments.
The first body portion 210 and the second body portion 220 are fixedly connected to the hub 110 and the drum 120, respectively, such that the first body portion 210 and the second body portion 220 can rotate relative to each other based on the relative rotation between the hub 110 and the drum 120.
In this embodiment, the first body portion 210 may include: the first screen comprises a first shell and a first screen positioned in the first shell; the first screen can be various display screens such as a liquid crystal display screen, an Organic Light Emitting Diode (OLED) display screen, an electronic ink display screen or a projection display screen.
In some embodiments, the second body portion 220 may include: the second casing and be located the second screen in the second casing. Similarly, the second screen may be a liquid crystal display screen, an Organic Light Emitting Diode (OLED) display screen, an electronic ink display screen, or a projection display screen.
In other embodiments, the second body portion 220 may further include: a second shell and a keyboard and/or a touch panel and the like positioned in the second shell.
Optionally, the first body portion 210 is fixedly connected to the drum 120 of the spindle structure;
the second body portion 220 is fixedly connected to the portion of the hub 110 exposed outside the drum 120.
For example, the shaft 110 may have a length greater than the length of the drum 120, the shaft 110 may be exposed from both ends of the drum 120, and the second body portion 220 may be connected to the exposed portions of both ends.
In some embodiments, the drum 120 may include: two drums 120 of identical construction are a first drum and a second drum, respectively. The first and second drums are fitted at two symmetrical positions that are symmetrical about the center point of the shaft center 110.
In any case, the second body portion 220 may be connected to the portion of the hub 110 exposed outside of the drum 120.
In this embodiment, at least one of the first body portion 210 and the second body portion 220 includes a display screen.
One specific example is provided below in connection with any of the embodiments described above:
for the current single-shaft electronic equipment, the maximum opening angle is usually 180 degrees, which is limited by the shaft itself and the connection structure between the electronic equipment and the shaft. An arc-shaped groove communicated with the hollow cavity where the axis 110 is located is formed in the single-shaft barrel, and the arc-shaped groove can be also called as a sliding track of the axis 110. The shaft 110 can move along a sliding track within the drum 120.
After the rotating drum 120 rotates to a certain position, the shaft center 110 slides along the sliding track under the continuous action of the acting force pushing the rotating drum 120, and after the shaft center 110 can not move any more or moves to a certain position, the acting force enables the rotating drum 120 to rotate continuously relative to the shaft center 110 again, so that the rotation of the single shaft center 110 up to 360 degrees can be effectively realized.
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 appended claims.
