Description

Technical Field

[0001] This invention relates to a hinge structure, and more particularly to a dual-axis hinge structure. Background Technology

[0002] Common foldable electronic devices include laptops, dual-screen laptops, foldable phones, foldable tablets, and similar products. Specifically, most common foldable electronic devices use a dual-axis hinge structure to pivotally connect two components. To enable the two components to rotate synchronously in opposite directions, existing dual-axis hinge structures primarily use four gears to achieve this synchronous, counter-rotating motion. However, such a design occupies a significant amount of space, hindering the trend towards thinner and lighter foldable electronic devices. Summary of the Invention

[0003] The present invention provides a hinge structure with a small volume, which helps to reduce the size of the foldable electronic device to which it is applied.

[0004] A dual-axis hinge structure of the present invention includes a fixing member, a first rotating shaft, a first guiding portion, a second rotating shaft, a second guiding portion, and a sliding guide member. The first rotating shaft passes through the fixing member. The first guiding portion is integrally formed on the first rotating shaft. The second rotating shaft passes through the fixing member and is arranged side-by-side with the first rotating shaft. The second guiding portion is integrally formed on the second rotating shaft. The first and second rotating shafts pass through the sliding guide member. The sliding guide member has a third guiding portion that engages with the first guiding portion and a fourth guiding portion that engages with the second guiding portion. When one or both of the first and second rotating shafts rotate relative to the fixing member, the sliding guide member slides relative to the first and second rotating shafts through the guiding engagement between the first and third guiding portions and / or between the second and fourth guiding portions, thereby causing the first and second rotating shafts to rotate synchronously in opposite directions by the same amount of rotation.

[0005] In one embodiment of the present invention, the first guide portion, the second guide portion, the third guide portion and the fourth guide portion described above are all spiral guide surfaces.

[0006] In one embodiment of the present invention, the above-described dual-axis hinge structure further includes a first co-moving member and a second co-moving member. The first co-moving member is connected to a first rotating shaft. A sliding guide member is located between the first guiding portion and the first co-moving member. The second co-moving member is connected to a second rotating shaft. The sliding guide member is located between the second guiding portion and the second co-moving member. The sliding guide member has a fifth guiding portion and a sixth guiding portion. The first co-moving member has a seventh guiding portion corresponding to the fifth guiding portion, and the second co-moving member has an eighth guiding portion corresponding to the sixth guiding portion.

[0007] In one embodiment of the present invention, the fifth, sixth, seventh and eighth guiding parts described above are spiral guiding surfaces.

[0008] In one embodiment of the present invention, the first guide portion and the second guide portion are respectively helical protrusions, and the third guide portion and the fourth guide portion are respectively helical grooves.

[0009] In one embodiment of the present invention, the sliding guide member has a first shaft hole and a second shaft hole. A third guide portion is located in the first shaft hole, and a fourth guide portion is located in the second shaft hole.

[0013] A dual-axis hinge structure of the present invention includes a fixing member, a first rotating shaft, a first guiding portion, a second rotating shaft, a second guiding portion, a first sliding guide member, and a second sliding guide member. The first rotating shaft passes through the fixing member. The first guiding portion is integrally formed on the first rotating shaft.

The second rotating shaft passes through the second sliding guide member. The second sliding guide member has a fourth guiding portion that cooperates with the second guiding portion and a pushing portion corresponding to the groove. The pushing portion slides within the groove. When one or both of the first and second rotating shafts rotate relative to the fixed member, the pushing part moves on one side of the slide groove until it abuts against the other side of the slide groove, and continues to rotate one or both of the first and second rotating shafts so that the first sliding guide and the second sliding guide push against each other, thereby causing the first sliding guide and the second sliding guide to slide relative to the first and second rotating shafts, so that the first and second rotating shafts rotate in opposite directions and the amount of rotation between the first and second rotating shafts has a difference.

[0073] Figure 1 This is a three-dimensional schematic diagram of the dual-axis hinge structure according to the first embodiment of the present invention. Figure 2 yes Figure 1 An exploded view of a dual-axis hinge structure. Figure 3 yes Figure 1 A partially enlarged schematic diagram of the dual-axis hinge structure. Figure 4 and Figure 5 yes Figure 2 This provides a 3D schematic diagram of the sliding guide from different viewpoints. Cartesian coordinates (x, y, z) are also provided to facilitate understanding the perspective relationships between the various views. Please refer to... Figure 1 , Figure 2 , Figure 4 as well as Figure 5 The dual-axis hinge structure 100 of this embodiment is applicable to foldable electronic devices, such as laptops, dual-screen laptops, foldable screen mobile phones, foldable screen tablet computers or similar electronic products. The dual-axis hinge structure 100 includes a fixing member 110, a first pivot 120, a first guide part 130, a second pivot 140, a second guide part 150, and a sliding guide member 160.

[0074] Specifically, both the first rotating shaft 120 and the second rotating shaft 140 pass through the fixing member 110 and the sliding guide member 160, with the second rotating shaft 140 arranged side by side with the first rotating shaft 120. The first guide portion 130 is integrally formed on the first rotating shaft 120, and the second guide portion 150 is integrally formed on the second rotating shaft 140. The sliding guide member 160 has a third guide portion 161 that cooperates with the first guide portion 130 and a fourth guide portion 162 that cooperates with the second guide portion 150.

[0075] In this embodiment, when one or both of the first rotating shaft 120 and the second rotating shaft 140 rotate relative to the fixed member 110, the sliding guide member 160 is driven to slide relative to the first rotating shaft 120 and the second rotating shaft 140 through the guiding engagement between the first guide portion 130 and the third guide portion 161 and / or between the second guide portion 150 and the fourth guide portion 162, thereby causing the first rotating shaft 120 and the second rotating shaft 140 to rotate synchronously in opposite directions by the same amount of rotation. Therefore, the dual-axis hinge structure 100 of the present invention does not require the use of four gears as in the conventional manner, thus having a smaller volume and helping to reduce the size of the applied foldable electronic device.

[0076] Please refer to Figure 1 , Figure 2 as well as Figure 3 The dual-axis hinge structure 100 also includes a first moving member 170, a second moving member 180, another fixing member 190, and a torsion member 195.

[0077] The first rotating shaft 120 has a first engaging surface 121, and a first co-moving member 170 is engaged with the first engaging surface 121 of the first rotating shaft 120 to rotate synchronously with the first rotating shaft 120. The second rotating shaft 140 has a second engaging surface 141, and a second co-moving member 180 is engaged with the second engaging surface 141 of the second rotating shaft 140 to rotate synchronously with the second rotating shaft 140.

[0078] The sliding guide 160 has a fifth guide portion 163 and a sixth guide portion 164. The first co-moving member 170 has a seventh guide portion 171 corresponding to the fifth guide portion 163, and the second co-moving member 180 has an eighth guide portion 181 corresponding to the sixth guide portion 164. In this embodiment, the first guide portion 130, the second guide portion 150, the third guide portion 161, the fourth guide portion 162, the fifth guide portion 163, the sixth guide portion 164, the seventh guide portion 171, and the eighth guide portion 181 are all helical guide surfaces. The helical guide surface defined here refers to these guide surfaces spirally surrounding their respective axes of rotation; in terms of the figures, the helical guide surfaces spirally surround the x-axis.

[0079] A sliding guide 160 is located between a fixed member 110 and a torque member 195, and is also located between a fixed member 110 and another fixed member 190, and is adapted to slide between the fixed member 110 and the other fixed member 190. A first co-moving member 170 and a second co-moving member 180 are located between the sliding guide 160 and the other fixed member 190. Another fixed member 190 is located between the first co-moving member 170 and the torque member 195, and is also located between the second co-moving member 180 and the torque member 195, wherein the torque member 195 provides torque for the rotation of the first rotating shaft 120 and the second rotating shaft 140.

[0080] The sliding guide 160 is slidably located between the first guide portion 130 and the seventh guide portion 171 of the first co-moving member 170, and the sliding guide 160 is slidably located between the second guide portion 150 and the eighth guide portion 181 of the second co-moving member 180. The first rotating shaft 120 and the second rotating shaft 140 pass through another fixing member 190 and the torque member 195.

[0081] Figure 6 yes Figure 1 The diagram shows the front view of the dual-axis hinge structure, which is the initial mode of the dual-axis hinge structure before rotation (the included angle is 0 degrees). Figure 7 yes Figure 6 A schematic diagram showing the transformation of the dual-axis hinge structure to another mode, with the included angle of the dual-axis hinge structure being 180 degrees. Figure 8 yes Figure 7 The diagram illustrates the transition from one mode to another, showing a 360-degree angle between the two-axis hinge structure. Please refer to... Figure 1 , Figure 2 , Figure 6 as well as Figure 7 In the dual-axis hinge structure 100 from Figure 6 The mode shown is switched to Figure 7 In the illustrated process, one or both of the first rotating shaft 120 and the second rotating shaft 140 rotate relative to the fixed member 110. The first guide part 130 pushes the third guide part 161 to slide the sliding guide member 160, the second guide part 150 pushes the fourth guide part 162 to slide the sliding guide member 160, the fifth guide part 163 slides relative to the seventh guide part 171, and the sixth guide part 164 slides relative to the eighth guide part 181, so that the first rotating shaft 120 and the second rotating shaft 140 can rotate synchronously in opposite directions by the same amount of rotation. In other words, the sliding guide member 160 only produces movement in the x-axis direction, and the first co-moving member 170 and the second co-moving member 180 rotate in opposite directions in the x-axis direction with the first rotating shaft 120 and the second rotating shaft 140, but do not produce movement in the x-axis direction.

[0082] Further reference Figure 8 In the dual-axis hinge structure 100 from Figure 7 The mode shown is switched to Figure 8In the illustrated process, the first guide section 130 continuously pushes the third guide section 161 to slide the sliding guide member 160, the second guide section 150 continuously pushes the fourth guide section 162 to slide the sliding guide member 160, the fifth guide section 163 continuously slides relative to the seventh guide section 171, and the sixth guide section 164 continuously slides relative to the eighth guide section 181, so that the first rotating shaft 120 and the second rotating shaft 140 can continuously and synchronously rotate in opposite directions by the same amount of rotation. Therefore, the sliding guide member 160 also only produces movement in the x-axis direction.

Figure 13 yes Figure 12 This diagram illustrates the transition from one dual-axis hinge structure to another, where the included angle of the dual-axis hinge is 360 degrees. Cartesian coordinates (x, y, z) are also provided to aid in understanding the visual relationships between the various views. Please refer to... Figure 9 , Figure 10 as well as Figure 11 The dual-axis hinge structure 200 of this embodiment includes a fixing member 210, a first rotating shaft 220, a first guiding part 230, a second rotating shaft 240, a second guiding part 250, and a sliding guiding member 260.

[0084] Specifically, both the first rotating shaft 220 and the second rotating shaft 240 pass through the fixing member 210 and the sliding guide member 260, with the second rotating shaft 240 arranged side by side with the first rotating shaft 220. The first guide portion 230 is integrally formed on the first rotating shaft 220, and the second guide portion 250 is integrally formed on the second rotating shaft 240. The sliding guide member 260 has a third guide portion 261 that cooperates with the first guide portion 230 and a fourth guide portion 262 that cooperates with the second guide portion 250.

[0085] In this embodiment, when one or both of the first rotating shaft 220 and the second rotating shaft 240 rotate relative to the fixed member 210, the sliding guide member 260, through the guiding engagement between the first guide portion 230 and the third guide portion 261 and / or between the second guide portion 250 and the fourth guide portion 262, drives the sliding guide member 260 to slide relative to the first rotating shaft 220 and the second rotating shaft 240, thereby causing the first rotating shaft 220 and the second rotating shaft 240 to rotate synchronously in opposite directions by the same amount of rotation. Therefore, the dual-axis hinge structure 200 of the present invention does not require the use of four gears as in the conventional manner, thus having a smaller volume and helping to reduce the size of the applied foldable electronic device.

[0086] The first rotating shaft 220 has an integrally formed first positioning part 222, and the second rotating shaft 240 has an integrally formed second positioning part 242. The first positioning part 222 is located between the fixing member 210 and the first guide part 230, and the second positioning part 242 is located between the fixing member 210 and the second guide part 250.

[0087] The sliding guide 260 has a first shaft hole 265 and a second shaft hole 266. A third guide portion 261 is located in the first shaft hole 265, and a fourth guide portion 262 is located in the second shaft hole 266. The first guide portion 230 and the second guide portion 250 are helical protrusions, and the third guide portion 261 and the fourth guide portion 262 are helical grooves. As shown in the figures, the first guide portion 230, the second guide portion 250, the third guide portion 261, and the fourth guide portion 262 are helically wound around the x-axis, but the present invention is not limited thereto.

[0088] The dual-axis hinge structure 200 also includes another fixing member 290 and a torque member 295. A sliding guide 260 is located between the fixing member 210 and the torque member 295, and is adapted to slide between the fixing member 210 and the other fixing member 290. The torque member 295 provides torque for the rotation of the first pivot 220 and the second pivot 240.

[0089] Please refer to Figure 10 , Figure 11 , Figure 12 as well as Figure 13 In the dual-axis hinge structure 200 from Figure 11 The mode shown is switched to Figure 12 The pattern shown and from Figure 12 The mode shown is switched to Figure 13In the illustrated process, the first guide section 230 slides the sliding guide member 260 via the third guide section 261, and the second guide section 250 slides the sliding guide member 260 via the fourth guide section 262, so that the first rotating shaft 220 and the second rotating shaft 240 can rotate synchronously in opposite directions by the same amount of rotation. In other words, the sliding guide member 260 only produces movement in the x-axis direction.

Figure 19 yes Figure 18 This diagram illustrates the transition from one dual-axis hinge structure to another, where the included angle of the dual-axis hinge is 360 degrees. Cartesian coordinates (x, y, z) are also provided to aid in understanding the visual relationships between the various views. Please refer to... Figure 14 , Figure 15 as well as Figure 16 The dual-axis hinge structure 300 of this embodiment includes a fixing member 310, a first rotating shaft 320, a first guiding part 330, a second rotating shaft 340, a second guiding part 350, a first sliding guide member 360A, and a second sliding guide member 360B.

[0091] Specifically, both the first rotating shaft 320 and the second rotating shaft 340 pass through the fixing member 310, and the first rotating shaft 320 and the second rotating shaft 340 are arranged side by side. The first guide portion 330 is integrally formed on the first rotating shaft 320, and the second guide portion 350 is integrally formed on the second rotating shaft 340. The first rotating shaft 320 passes through the first sliding guide member 360A, and the second rotating shaft 340 passes through the second sliding guide member 360B. The first sliding guide member 360A has a third guide portion 361A and a groove 362A that cooperate with the first guide portion 330, and the second sliding guide member 360B has a fourth guide portion 361B that cooperates with the second guide portion 350 and a pushing portion 362B corresponding to the groove 362A, wherein the pushing portion 362B slides within the groove 362A.

[0092] Please refer to Figure 15 , Figure 17 , Figure 18 as well as Figure 19When one or both of the first rotating shaft 320 and the second rotating shaft 340 rotate relative to the fixed member 310, the sliding groove 362A and the pushing part 362B first slide and then come into contact, causing the first sliding guide 360A and the second sliding guide 360B to push each other, thereby driving the first sliding guide 360A and the second sliding guide 360B to slide relative to the first rotating shaft 320 and the second rotating shaft 340. It should be noted that, like the first embodiment and the second embodiment, this embodiment causes the first rotating shaft 320 and the second rotating shaft 340 to rotate in opposite directions; unlike the first embodiment and the second embodiment, this embodiment allows the amount of rotation between the first rotating shaft 320 and the second rotating shaft 340 to have a difference.

[0093] In other words, by varying the sliding distance between the pushing part 362B and the slide groove 362A, a certain amount of free travel is generated in the movement of either the first sliding guide 360A or the second sliding guide 360B. Thus, after one of the first rotating shafts 320 and 340 rotates by a certain amount, the first rotating shaft 320 and the second rotating shaft 340 begin to rotate synchronously in opposite directions. Therefore, the dual-axis hinge structure 300 of the present invention does not require four gears as in the conventional method, thus having a smaller volume and helping to reduce the size of the applied foldable electronic device.

[0094] On the other hand, the most obvious effect of the idle stroke is: rotation from 0 degrees to 360 degrees (in sequence from...). Figures 17 to 19 (the direction of rotation), the second shaft 340 is more easily induced to rotate, and rotates from 360 degrees to 0 degrees (in sequence from...). Figures 19 to 17 During the rotation (in another direction), the first pivot 320 is more easily actuated. Therefore, applying the dual-axis hinge structure 300 of the third embodiment to a foldable electronic device can provide the user with the starting angle at the moment of preparing to open the screen (e.g., from 0 degrees to 24 degrees) and preparing to close the screen (e.g., from 360 degrees to 336 degrees), allowing for single-handed and / or less force application, and providing the user with different tactile sensations.

[0095] Specifically, the dual-axis hinge structure 300 from Figure 17 The initial mode rotates to Figure 18In another mode of operation, the easily rotatable second pivot 340 first rotates a certain amount of rotation (e.g., 24 degrees) relative to the fixed member 310 toward the negative x-axis, while the pushing part 362B moves along the x-axis from one side S1 of the slide groove 362A until it abuts against the other side S2 of the slide groove 362A. Up to this point, the first pivot 320 has not rotated. In other words, the distance difference in sliding distance between the pushing part 362B and the slide groove 362A causes the second sliding guide 360B to have a free travel, preventing it from driving the first sliding guide 360A. Thus, in practical applications, when the second pivot 340 and the first pivot 320 are respectively mounted on the screen side and the main unit side of a foldable electronic device, the free travel of the second sliding guide 360B provides the user with the effect of being able to open the screen with one hand and / or with a small amount of force at the moment of opening, and subsequently, it is preferable to use both hands to apply even force to flip the screen side and the main unit side. Then, once the second rotating shaft 340 rotates beyond the aforementioned certain amount of rotation (i.e., the aforementioned 24 degrees), the pushing part 362B continuously abuts against the other side S2 of the slide groove 362A (as shown in the image). Figure 18 As shown), at this moment, the second sliding guide 360B and the first sliding guide 360A begin to push against each other, causing the second sliding guide 360B and the first sliding guide 360A to slide together relative to the second rotating shaft 340 and the first rotating shaft 320 along a positive x-axis. This causes the first rotating shaft 320 and the second rotating shaft 340 to rotate in opposite directions with a difference in rotational amount until... Figure 18 Another pattern is shown.

[0096] It should be noted here that... Figure 18 The second rotating shaft 340 will first rotate towards the negative x-axis to a preset 90 degrees, but the first rotating shaft 320 will only rotate towards the positive x-axis by 66 degrees, leaving a 24-degree difference before reaching the preset 90 degrees. During the rotation of the first rotating shaft 320 from 66 degrees to the preset 90 degrees, the first sliding guide 360A will continuously move along the positive x-axis (the second sliding guide 360B will not move temporarily), causing the slide groove 362A to move until it reaches one side S1 of the slide groove 362A (e.g., ...). Figure 19 As shown, the slide groove 362A (slide 360A) abuts against the pusher 362B. Then, once the first rotating shaft 320 rotates to a preset 90 degrees, one side S1 of the slide groove 362A continues to abut against the pusher 362B. At this moment, the first sliding guide 360A and the second sliding guide 360B begin to push against each other, causing the first sliding guide 360A and the second sliding guide 360B to continue sliding along the positive x-axis relative to the first rotating shaft 320 and the second rotating shaft 340. This causes the first rotating shaft 320 and the second rotating shaft 340 to rotate in opposite directions and operate with the same differential rotational amount until… Figure 19 Another pattern shown.

[0097] Conversely, if the dual-axis hinge structure 300 is to be moved from... Figure 19 Another mode reset to Figure 18In another mode, the easily rotatable first pivot 320 first rotates relative to the fixed member 310 towards the negative x-axis by a certain amount of reverse momentum (e.g., -24 degrees), while the slide 362A moves along the negative x-axis until the other side S2 of the slide 362A abuts against the push member 362B. Up to this point, the second pivot 340 has not rotated and the first sliding guide 360A has a free travel and cannot push the second sliding guide 360B. In practical applications, this provides the user with the ability to close the screen in 360-degree flip mode with one hand and / or with minimal force. Then, as soon as the first pivot 320 rotates beyond the aforementioned certain amount of reverse momentum (i.e., the aforementioned -24 degrees), the other side S2 of the slide 362A (e.g., -24 degrees) moves towards the negative x-axis until the other side S2 of the slide 362A (e.g., -24 degrees) abuts against the push member 362B. Figure 18 The position shown will continuously abut against the pushing part 362B. At this moment, the first sliding guide 360A and the second sliding guide 360B begin to push against each other, causing the first sliding guide 360A and the second sliding guide 360B to slide together relative to the second rotating shaft 340 and the first rotating shaft 320 along a negative x-axis. As a result, the first rotating shaft 320 and the second rotating shaft 340 rotate in opposite directions and operate with a difference in rotation until they are reset. Figure 18 Another pattern is shown.

[0098] For resetting Figure 18 In the process, the first rotating shaft 320 will first rotate towards the negative x-axis to a preset -90 degrees, but the second rotating shaft 340 will only rotate towards the positive x-axis by -66 degrees, which is -24 degrees short of the preset -90 degrees. During the rotation of the second rotating shaft 340 from -66 degrees to the preset -90 degrees, the second sliding guide 360B will continuously move along the negative x-axis (the first sliding guide 360A will not move temporarily), causing the pushing part 362B to move from the other side S2 of the slide groove 362A until it abuts against one side S1 of the slide groove 362A (e.g., ...). Figure 17 (as shown in the image). Then, once the second rotating shaft 340 rotates to a preset -90 degrees, the pushing part 362B continues to abut against one side S1 of the slide groove 362A. At this moment, the first sliding guide 360A and the second sliding guide 360B push against each other, causing the first sliding guide 360A and the second sliding guide 360B to continue sliding along a negative x-axis relative to the first rotating shaft 320 and the second rotating shaft 340, thereby causing the first rotating shaft 320 and the second rotating shaft 340 to rotate in the opposite direction and reset to their original positions. Figure 17 The initial pattern shown.

[0099] The dual-axis hinge structure 300 also includes a first moving member 370, a second moving member 380, another fixing member 390, and a torsion member 395.

The second rotating shaft 340 has a second engaging surface 341, and a second cooperating member 380 is engaged with the second engaging surface 341 of the second rotating shaft 340 to rotate synchronously with the second rotating shaft 340.

[0101] The first sliding guide 360A has a fifth guide portion 363A, and the second sliding guide 360B has a sixth guide portion 363B. The first co-moving member 370 has a seventh guide portion 371 corresponding to the fifth guide portion 363A, and the second co-moving member 380 has an eighth guide portion 381 corresponding to the sixth guide portion 363B. In this embodiment, the first guide portion 330, the second guide portion 350, the third guide portion 361A, the fourth guide portion 361B, the fifth guide portion 363A, the sixth guide portion 363B, the seventh guide portion 371, and the eighth guide portion 381 are all helical guide surfaces. The helical guide surface defined here refers to these guide surfaces spirally surrounding their respective axes of rotation; in terms of the figures, the helical guide surfaces spirally surround the x-axis.

[0102] The first sliding guide 360A is located between the first guide portion 330 and the first co-moving member 370, and the second sliding guide 360B is located between the second guide portion 350 and the second co-moving member 380. It should be noted that, as in the first embodiment, in the third embodiment, the first co-moving member 370 and the second co-moving member 380 rotate in opposite directions along the x-axis with the first rotating shaft 320 and the second rotating shaft 340, but do not produce any movement along the x-axis.

[0103] The first rotating shaft 320 and the second rotating shaft 340 pass through another fixing member 390. The first sliding guide 360A and the second sliding guide 360B are located between the fixing member 310 and the other fixing member 390, and the first sliding guide 360A and the second sliding guide 360B are adapted to slide between the fixing member 310 and the other fixing member 390.
