Detailed Description
Hereinafter, an electronic device including a bevel-gear type biaxial hinge structure according to a preferred embodiment of the present invention will be described in detail with reference to the drawings.
Referring to fig. 1 to 7, an electronic apparatus including a bevel-gear type biaxial hinge structure according to an embodiment of the present invention has the following features.
The present invention is an electronic device (for example, a mobile device such as a notebook computer or a tablet computer) having a bevel gear type biaxial hinge structure in which a main body 10 having an input part and a display part 11 for displaying image information are hinged so as to be foldable relative to each other, the electronic device having the bevel gear type biaxial hinge structure, comprising:
a first driving shaft 15 including a first fixing groove 13 for fixing the first hinge 12 mounted to the body 10 and a first bevel gear 14 formed at one side of an outer circumference;
a second driving shaft 19 opposite to the first driving shaft 15, including a second fixing groove 17 for fixing the second hinge 16 mounted on the display unit 11 and a second bevel gear 18 formed on one side of the outer circumference; and (c) a second step of,
a linkage shaft 21 having third bevel gears 20 formed at both ends thereof to be engaged with the first bevel gears 14 and the second bevel gears 18 (i.e., formed such that the directions of the first and second driving shafts 15 and 19 are maintained at 90 degrees to the direction of the linkage shaft 21),
when the main body 10 and the display unit 11 are folded relative to each other within an arbitrary angular range, one of the first and second drive shafts 15 and 19 performs a rotational motion in a forward direction or a reverse direction, and the other of the first and second drive shafts 15 and 19 performs a rotational motion in an opposite direction at the same speed by the third bevel gear 20.
As shown in fig. 1, 2a, 2b, and 3, the electronic device having the bevel-gear type biaxial hinge structure according to the more preferred embodiment is characterized in that the above-described interlocking shaft 21 further includes a fixed block 25, and the fixed block 25 is rotatably coupled to the interlocking shaft 21 on one side and is formed with engaging hubs 24 on the other side, into which the extending shafts 22 and 23 of the first and second drive shafts 15 and 19 are rotatably fitted, respectively.
Therefore, when the main body 10 and the display unit 11 are folded in an arbitrary angle range, the third bevel gear 20 can be prevented from moving in the left-right direction and being disengaged from the first bevel gear 14 or the second bevel gear 18, and smooth interlocking movement of the first, second, and third bevel gears 14, 18, and 20 can be ensured.
Accordingly, when the main body 10 or the display portion 11 described above is folded relatively within an arbitrary angle range, the main body 10 or the display portion 11 can be folded relatively by rotating the first bevel gear 14 or the second bevel gear 18 by the third bevel gear 20 which meshes with and interlocks with the first and second bevel gears 14 and 18.
At this time, the third bevel gear 20 engaged with the first and second bevel gears 14 and 18 described above is formed at both ends of the interlocking shaft 21, and the fixing block 25 to which the interlocking shaft 21 is rotatably coupled on one side prevents the third bevel gear 20 from moving in the left-right direction and being separated from the first bevel gear 14 or the second bevel gear 18, and ensures smooth interlocking movement of the first, second, and third bevel gears 14, 18, and 20, thereby improving reliability of the biaxial hinge structure.
As shown in fig. 4, when the third bevel gear 20 is formed separately from the interlocking shaft 21 and coupled to both ends of the interlocking shaft 21, the workability of processing the third bevel gear 20 can be improved, and when the third bevel gear 20 is integrally formed at both ends of the interlocking shaft 21, the workability of assembling them can be improved.
As shown in fig. 5, the electronic device having the bevel-gear type biaxial hinge structure according to the present embodiment is characterized in that it can be applied to an electronic device having a short inter-axial distance L1 or L2 or an electronic device having a relatively long inter-axial distance L1 or L2 when the inter-axial distances L1 or L2 between the first and second fixing grooves 13 and 17 of the first and second drive shafts 15 and 19 are variably adjusted.
Accordingly, the aforementioned length of the interlocking shaft 21 of the third bevel gear 20 is variably adjusted to shorten the inter-axis distance L1 between the first and second drive shafts 15 and 19 or to lengthen the inter-axis distance L2 between the first and second drive shafts 15 and 19, and thus the present invention can be variously applied to electronic devices having a short inter-axis distance L1 or electronic devices having a relatively long inter-axis distance L2 using the same two-axis hinge structure.
As shown in fig. 7, the electronic device having the bevel-gear type biaxial hinge structure according to the present embodiment further includes a case 26 for covering and protecting the first and second drive shafts 15 and 19 and the fixing block 25.
Accordingly, in a case where the body 10 and the display part 11 described above are relatively folded at an arbitrary angle, the first and second driving shafts 15 and 19 and the fixing block 25 are received and wrapped by the housing 26, and thus, the appearance of the biaxial hinge structure is neat and they can be protected from the outside.
An electronic device including a bevel-gear type biaxial hinge structure according to an embodiment of the present invention will be described below with reference to the drawings.
As shown in fig. 1 to 7, when the main body 10 and the display unit 11 are folded relative to each other, and when the folded angle between the main body 10 and the display unit 11 is maintained at 0 degree or 360 degrees, the first and second hinges 12 and 16 attached to the main body 10 and the display unit 11 are maintained in a horizontal (parallel) state.
When the folding angle of the main body 10 and the display unit 11 is gradually increased from 90 degrees to 270 degrees, the first and second hinges 12 and 16 are rotated to 90 degrees, 180 degrees, and 270 degrees, and at this time, the first bevel gear 14 or the second bevel gear 18 formed on the first and second drive shafts 15 and 19 attached to the main body 10 and the display unit 11 are rotated in the opposite direction, and the third bevel gear 20 is simultaneously linked.
That is, as shown in fig. 2a, when the main body 10 or the display part 11 is folded relatively, the first bevel gear 14 rotates in a reverse direction (counterclockwise direction) and the second bevel gear 18 rotates in a forward direction (clockwise direction), the third bevel gear 20 rotates in a reverse direction.
On the contrary, as shown in fig. 2b, when the main body 10 or the display part 11 is folded relatively, the first bevel gear 14 rotates in a forward direction (clockwise direction) and the second bevel gear 18 rotates in a reverse direction (counterclockwise direction), the third bevel gear 20 rotates in a forward direction.
As described above, the first and second hinges 12 and 16 integrally fixed to the main body 10 and the display 11 are fixed to the first and second fixing grooves 13 and 17 of the first and second driving shafts 15 and 19, and the first and second bevel gears 14 and 18 of the first and second driving shafts 15 and 19 are engaged with the third bevel gear 20 (interlocked by the first bevel gear 14 or the second bevel gear 18) of the interlocking shaft 21, so that the first and second driving shafts 15 and 19 and the interlocking shaft 21 are simultaneously interlocked and rotated when the main body 10 or the display 11 is folded relatively.
That is, in the case where one of the first and second drive shafts 15, 19 described above is rotated, the first bevel gear 14 or the second bevel gear 18 of the first drive shaft 15 or the second drive shaft 19 is rotated, and the third bevel gear 20 engaged with the first and second bevel gears 14, 18 is rotated, whereby the other of the first and second drive shafts 15, 19 is rotated in the opposite direction.
At this time, since the first and second driving shafts 15 and 19 maintain the same speed although the rotation directions are opposite to each other, the main body 10 and the display unit 11 can be folded at any angle relative to each other.
Although the present invention has been described in the foregoing specification with reference to the preferred embodiments, those skilled in the art will appreciate that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the appended claims.
