Description

[Technical Field]

[0001] This invention relates to an electronic device, and more particularly to an electronic device having a torque adjustment design. [Previous Technology]

[0002] A notebook computer is typically composed of a first unit with logical operation capabilities, a second unit with image display capabilities, and a hinge structure. The second unit is connected to the first unit through the hinge structure, so the second unit can rotate relative to the first unit to switch between a closed state and an open state.

[0003] In detail, the positioning torque generated by the hinge structure can be used to fix the state of the second body relative to the first body, such as fixing the second body in a closed state or fixing the opening angle of the second body relative to the first body. Generally speaking, the positioning torque value that the hinge structure can generate is set at the factory, so it is difficult for the user to adjust it independently according to the actual use situation, and it lacks operational flexibility. [Summary of the Invention]

[0004] The present invention provides an electronic device that not only has excellent operational flexibility and convenience, but also meets the user's need for independent operation.

[0005] One embodiment of the present invention provides an electronic device including a first body, a second body, a hinge structure, and a torque adjustment member. The second body is pivotally connected to the first body via the hinge structure and is adapted to rotate relative to the first body about an axis. The torque adjustment member is rotatably disposed between the first body and the second body. The torque adjustment member includes an operating part and an adjusting part, and the adjusting part engages with the hinge structure. When the operating part contacts the first body, the torque of the hinge structure is maintained at a preset torque value. When the operating part rotates about an axis toward the second body and separates from the first body, the adjusting part increases the torque of the hinge structure to be greater than the preset torque value.

[0006] In one embodiment of the present invention, the first body described above has a groove adjacent to the hinge structure, and the operating part is housed within the groove. When the operating part is positioned within the groove, the torque of the hinge structure is maintained at a preset torque value. When the operating part is removed from the groove, the adjusting part increases the torque of the hinge structure to a value greater than the preset torque value.

[0007] In one embodiment of the present invention, the second body is rotated along a first rotation direction to unfold from the first body, and the torque adjustment member is adapted to rotate along a second rotation direction that is in the same direction as the first rotation direction to increase the torque of the hinge structure.

[0008] In one embodiment of the present invention, the second body is rotated in a third rotation direction opposite to the first rotation direction to close to the first body, and the torque adjustment member is adapted to rotate in a fourth rotation direction in the same direction as the third rotation direction to reduce the torque of the hinge structure.

[0009] In one embodiment of the present invention, the second body is adapted to be extended to the maximum extension angle relative to the first body. When the operating part moves away from the first body and rotates to contact the second body which is maintained at the maximum extension angle, the adjusting part adjusts the torque of the hinge structure to the maximum torque value.

[0010] In one embodiment of the present invention, the first body has a pivot groove, and the second body includes a first pivot portion and a second pivot portion arranged side by side. An adjustment portion, the first pivot portion, and the second pivot portion are disposed within the pivot groove, and the adjustment portion is located between the first pivot portion and the second pivot portion. A hinge structure passes through the second pivot portion to engage with the adjustment portion.

[0011] In one embodiment of the present invention, the hinge structure includes a first bracket, a rotating shaft, a second bracket, a set of washers, and an adjusting nut. The first bracket is fixedly connected to a first body. The rotating shaft is fixedly connected to the first bracket. The second bracket is fixedly connected to a second body and rotatably connected to the rotating shaft. The set of washers is disposed on the rotating shaft. The adjusting nut is screwed to the end of the rotating shaft. The set of washers is positioned between the adjusting nut and the second bracket, and the adjusting part engages with the adjusting nut.

[0012] In one embodiment of the present invention, the adjustment part has an adjustment hole that cooperates with the adjustment nut, and the adjustment hole is sleeved on the adjustment nut.

[0013] In one embodiment of the present invention, the above-mentioned rotating shaft and adjusting part are coaxially arranged.

[0014] Another embodiment of the present invention provides an electronic device including a first body, a second body, a hinge structure, and a torque adjustment member. The second body is pivotally connected to the first body via the hinge structure. The torque adjustment member is rotatably and slidably disposed between the first body and the second body. The torque adjustment member includes an operating part and an adjusting part, and the adjusting part is detachably engaged with the hinge structure. When the operating part contacts the first body, the torque of the hinge structure remains at a preset torque value. As the operating part rotates about the axis through the hinge structure toward the second body and separates from the first body, the adjusting part increases the torque of the hinge structure to be greater than the preset torque value. When the torque adjustment member slides along a first direction parallel to the axis to disengage the adjusting part from the hinge structure, the torque of the hinge structure is locked.

[0015] In another embodiment of the present invention, after the torque of the hinge structure is locked, the operating part is adapted to rotate around the axis toward the first body to contact the first body, and then the torque adjusting member is slid along a second direction opposite to the first direction so that the adjusting part engages with the hinge structure.

[0016] In another embodiment of the present invention, the side of the first body described above has a finger-receiving groove and a recess adjacent to the hinge structure, and the finger-receiving groove and the recess are connected. The operating part and the adjusting part are respectively housed in the finger-receiving groove and the recess. When the operating part is positioned in the finger-receiving groove, the torque of the hinge structure is maintained at a preset torque value. When the operating part rotates around the axis and moves out of the finger-receiving groove, the adjusting part rotates in the recess and adjusts the torque of the hinge structure to be greater than the preset torque value.

[0017] In another embodiment of the present invention, the first body includes a first pivot portion adjacent to the groove, and the second body includes a second pivot portion rotatably connected to the first pivot portion. A portion of the hinge structure is disposed within the first pivot portion, and an adjustment portion is inserted into the first pivot portion.

[0018] In another embodiment of the present invention, the second body is rotated along the first rotation direction to unfold on the first body, and the torque adjustment member is adapted to rotate along the second rotation direction in the same direction as the first rotation direction to increase the torque of the hinge structure.

[0019] In another embodiment of the present invention, the two bodies are rotated in a third rotation direction opposite to the first rotation direction to close to the first body, and the torque adjustment member is adapted to rotate in a fourth rotation direction in the same direction as the third rotation direction to reduce the torque of the hinge structure.

[0020] In another embodiment of the present invention, when the adjustment part is separated from the hinge structure, the torque of the hinge structure does not change with the torque adjustment member rotating along the second rotation direction or the fourth rotation direction.

[0021] In another embodiment of the present invention, the hinge structure described above includes a first bracket, a rotating shaft, a second bracket, a set of washers, and an adjusting nut. The first bracket is fixedly connected to a first body. The rotating shaft is fixedly connected to the first bracket. The second bracket is fixedly connected to a second body and rotatably connected to the rotating shaft. The set of washers is disposed on the rotating shaft. The adjusting nut is screwed to the end of the rotating shaft. The set of washers is positioned between the adjusting nut and the second bracket, and the adjusting part engages with the adjusting nut.

[0022] In another embodiment of the present invention, the hinge adjustment part described above has an adjustment hole that cooperates with the adjustment nut, and the adjustment hole is detachably sleeved on the adjustment nut.

[0023] In another embodiment of the present invention, the above-mentioned rotating shaft and adjusting part are coaxially arranged.

[0024] Based on the above, depending on the actual usage, the user can adjust the torque of the hinge structure by rotating the torque adjustment component. Therefore, the electronic device of the present invention not only has excellent operational flexibility and convenience, but also meets the user's need for independent operation.

[0025] In order to make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below, and detailed descriptions are given in conjunction with the accompanying drawings.

Implementation Method

[0027] FIG1A is a schematic diagram of the electronic device of the first embodiment of the present invention in a first mode. FIG1B is a schematic diagram of the internal structure of the electronic device of FIG1A and the torque adjustment member and hinge structure. FIG1C is a schematic diagram of the internal structure of the electronic device of FIG1B when switched to a second mode, wherein the position of the torque adjustment member 140 in FIG1C is specifically indicated by solid lines to clearly show the position of the torque adjustment member 140 in the following description. Referring to FIG1A and FIG1B, in this embodiment, the electronic device 100 may be a notebook computer and includes a first body 110, a second body 120, a hinge structure 130 and a torque adjustment member 140.

[0028] The second body 120 is pivotally connected to the first body 110 via a hinge structure 130, and the torque generated by the hinge structure 130 can fix the unfolding angle of the second body 120 relative to the first body 110. On the other hand, a torque adjustment member 140 is rotatably disposed between the first body 110 and the second body 120, wherein the torque adjustment member 140 includes an operating part 141 and an adjusting part 142, and the adjusting part 142 engages with the hinge structure 130.

[0029] As shown in Figures 1A and 1B, when the operating part 141 contacts the first body 110, the torque of the hinge structure 130 remains at a preset torque value. As shown in Figure 1C, depending on the actual usage, the user can rotate the torque adjustment part 140 to adjust the torque of the hinge structure 130. Specifically, the user can apply force to the operating part 141, causing the operating part 141 to rotate towards the second body 120 and separate from the first body 110. At the same time, the adjustment part 142, which rotates synchronously with the operating part 141, can adjust the torque of the hinge structure 130 to be greater than the preset torque value. After adjusting the torque of the hinge structure 130 to be greater than the preset torque value, it is possible to avoid the second body 120 from wobbling or accidentally falling due to insufficient positioning torque after unfolding relative to the first body 110.

[0030] As shown in Figures 1A to 1C, the second body 120 is adapted to rotate along a first rotation direction R1 to unfold onto the first body 110, and to rotate along a third rotation direction R3 opposite to the first rotation direction R1 to close onto the first body 110. On the other hand, the torque adjustment member 140 is adapted to rotate along a second rotation direction R2 in the same direction as the first rotation direction R1 to increase the torque of the hinge structure 130, and to rotate along a fourth rotation direction R4 in the same direction as the third rotation direction R3 to decrease the torque of the hinge structure 130.

[0031] Specifically, the user can apply force to operate the operating part 141 to control the adjustment part 142 to rotate in the second rotation direction R2, thereby increasing the torque of the hinge structure 130 by rotating the adjustment part 142. Conversely, the user can apply force to press down on the operating part 141 to control the adjustment part 142 to rotate in the fourth rotation direction R4, thereby decreasing the torque of the hinge structure 130 by rotating the adjustment part 142 in the opposite direction.

[0032] As shown in Figures 1A to 1C, the first body 110 has a groove 111 adjacent to the hinge structure 130, and the operating part 141 is housed within the groove 111. When the operating part 141 is positioned within the groove 111, the torque of the hinge structure 130 remains at a preset torque value. Conversely, when the operating part 141 moves out of the groove 111, the adjusting part 142, which rotates synchronously with the operating part 141, adjusts the torque of the hinge structure 130 to be greater than the preset torque value.

[0033] After the second body 120 is extended to the maximum extension angle MA relative to the first body 110 along the first rotation direction R1, the user can apply force to move the operating part 141 away from the first body 110. For example, the user can apply force to move the operating part 141 out of the groove 111 and rotate it along the second rotation direction R2 until it contacts the second body 120 which is held at the maximum extension angle MA. At the same time, the adjustment part 142, which rotates synchronously with the operating part 141, adjusts the torque of the hinge structure 130 to the maximum torque value.

[0034] Conversely, during the process of the second body 120 rotating along the third rotation direction R3 to close with the first body 110, the second body 120 can push the operating part 141, which has not yet returned to its initial position, to rotate along the fourth rotation direction R4, so as to reduce the torque of the hinge structure 130 by means of the adjusting part 142 rotating synchronously with the operating part 141. Specifically, when the operating part 141 rotates along the fourth rotation direction R4 and re-contacts the first body 110, the operating part 141 moves back into the groove 111, and the adjusting part 142 rotating synchronously with the operating part 141 adjusts the torque of the hinge structure 130 back to the preset torque value.

[0035] As shown in Figures 1B and 1C, the first body 110 further has a pivot groove 112 communicating with the recess 111, and the second body 120 includes a first pivot portion 121 and a second pivot portion 122 arranged side by side. Specifically, the adjustment portion 142, the first pivot portion 121, and the second pivot portion 122 are disposed within the pivot groove 112, and the adjustment portion 142 is located between the first pivot portion 121 and the second pivot portion 122. On the other hand, the hinge structure 130 passes through the second pivot portion 122 and is inserted into the adjustment portion 142 to engage with it.

[0036] In this embodiment, the hinge structure 130 includes a first bracket 131, a rotating shaft 132, a second bracket 133, a washer assembly 134, and an adjusting nut 135. The first bracket 131 is fixedly connected to the first body 110, and the rotating shaft 132 is fixedly connected to the first bracket 131. The second bracket 133 is fixedly connected to the second body 120 and rotatably connected to the rotating shaft 132. The washer assembly 134 is disposed on the rotating shaft 132, and the adjusting nut 135 is screwed to the end of the rotating shaft 132.

[0037] The pivot 132 and the adjusting part 142 are coaxially configured, wherein the pivot 132 passes through the second pivot part 122, and the shim set 134 is located inside the second pivot part 122. In addition, the end of the pivot 132 and the adjusting nut 135 are inserted into the adjusting part 142, and the adjusting part 142 engages with the adjusting nut 135. Furthermore, the shim set 134 is positioned between the adjusting nut 135 and the second bracket 133. The user can apply force to the operating part 141 to control the adjusting part 142 to rotate along the second rotation direction R2, so that the adjusting nut 135 is rotated by the adjusting part 142, causing the adjusting nut 135 to move on the pivot 132 closer to the shim set 134, and increasing the tightness of the shim set 134 and the frictional resistance between the shim set 134 and the second bracket 133, so as to achieve the effect of increasing the torque of the hinge structure 130.

[0038] In contrast, the user can apply force to press down the operating part 141 to control the adjustment part 142 to rotate in the fourth rotation direction R4, so that the adjustment nut 135 can be rotated by the adjustment part 142, so that the adjustment nut 135 moves away from the shim group 134 on the rotating shaft 132, and reduces the amount of tightening on the shim group 134 and the frictional resistance between the shim group 134 and the second bracket 133, so as to achieve the effect of reducing the torque of the hinge structure 130.

[0039] As shown in Figures 1B and 1C, the second body 120 is adapted to rotate relative to the first body 110 about an axis AX passing through a pivot 132, while the operating unit 141 is adapted to rotate between the first body 110 and the second body 120 about the axis AX. When the operating unit 141 rotates about the axis AX or along the second rotation direction R2 toward the second body 120 and separates from the first body 110, the adjusting unit 142 increases the torque of the hinge structure 130 to a value greater than a preset torque value. Conversely, when the operating unit 141 rotates about the axis AX or along the fourth rotation direction R4 toward the first body 110, the adjusting unit 142 decreases the torque of the hinge structure 130.

[0040] As shown in FIG1B, the adjusting part 142 has an adjusting hole 142a that mates with the adjusting nut 135, and the adjusting hole 142a is fitted onto the adjusting nut 135. For example, the adjusting hole 142a may be a hexagonal hole, and the adjusting nut 135 may be a hexagonal nut that mates with the hexagonal hole, but this is not a limitation.

[0041] FIG2A is a schematic diagram of the electronic device of the second embodiment of the present invention in a first mode. FIG2B is a schematic diagram of the internal structure of the electronic device of FIG2A. FIG2C is a schematic diagram of the torque adjustment member and hinge structure of FIG2B from two different perspectives. Referring to FIG2A to FIG2C, in this embodiment, the electronic device 200 may be a notebook computer and includes a first body 210, a second body 220, a hinge structure 230 and a torque adjustment member 240.

[0042] The second body 220 is pivotally connected to the first body 210 via a hinge structure 230, and the torque generated by the hinge structure 230 can fix the unfolding angle of the second body 220 relative to the first body 210. On the other hand, a torque adjustment member 240 is rotatably and slidably disposed between the first body 210 and the second body 220, wherein the torque adjustment member 240 includes an operating part 241 and an adjusting part 242, and the adjusting part 242 engages with the hinge structure 230.

[0043] Figure 2D is a schematic diagram of the internal structure of the electronic device 2B when switching to the second mode. As shown in Figures 2A and 2B, when the operating part 241 contacts the first body 210, the torque of the hinge structure 130 is maintained at a preset torque value. As shown in Figure 2D, depending on the actual usage, the user can rotate the torque adjustment part 240 to adjust the torque of the hinge structure 230. Specifically, the user can apply force to the operating part 241, causing the operating part 241 to rotate around the axis AX passing through the hinge structure 230 toward the second body 220 and separate from the first body 210. At the same time, the adjustment part 242, which rotates synchronously with the operating part 241, can increase the torque of the hinge structure 230 to be greater than the preset torque value. After the torque of the hinge structure 230 is increased to be greater than the preset torque value, it is possible to avoid the second body 220 from wobbling or accidentally falling due to insufficient positioning torque after unfolding relative to the first body 210.

[0044] Figures 2E and 2F are internal structural schematic diagrams of the process by which the second body of Figure 2D closes to the first body. As shown in Figures 2B, 2D, 2E, and 2F, the second body 220 is adapted to rotate along a first rotation direction R1 to unfold onto the first body 210, and to rotate along a third rotation direction R3 opposite to the first rotation direction R1 to close onto the first body 210. On the other hand, the torque adjustment member 240 is adapted to rotate along a second rotation direction R2 in the same direction as the first rotation direction R1 to increase the torque of the hinge structure 230, and to rotate along a fourth rotation direction R4 in the same direction as the third rotation direction R3 to decrease the torque of the hinge structure 230.

[0045] Specifically, the user can apply force to operate the operating part 241 to control the adjusting part 242 to rotate in the second rotation direction R2, thereby increasing the torque of the hinge structure 230. Conversely, the user can apply force to press down on the operating part 241 to control the adjusting part 242 to rotate in the fourth rotation direction R4, thereby decreasing the torque of the hinge structure 230.

[0046] The side of the first body 210 has a finger-receiving groove 211 and a recess 212 adjacent to the hinge structure 230, wherein the finger-receiving groove 211 and the recess 212 are connected, and the operating part 241 and the adjusting part 242 are respectively housed in the finger-receiving groove 211 and the recess 212. When the operating part 241 is positioned in the finger-receiving groove 211, the torque of the hinge structure 230 is maintained at a preset torque value. Conversely, when the operating part 241 rotates around the axis AX along the second rotation direction R2 and moves out of the finger-receiving groove 211, the adjusting part 242 rotates synchronously in the recess 212 and adjusts the torque of the hinge structure 230 to be greater than the preset torque value.

[0047] During the process of the second body 220 rotating in the third rotation direction R3 to close with the first body 210, the second body 220 can push the operating part 241, which has moved out of the finger groove 211, to rotate in the fourth rotation direction R4, so as to reduce the torque of the hinge structure 130 by means of the adjusting part 242, which rotates synchronously with the operating part 241. Specifically, when the operating part 241 rotates in the fourth rotation direction R4 and comes into contact with the first body 210 again, the operating part 241 moves back into the finger groove 211, and the adjusting part 242, which rotates synchronously with the operating part 241, adjusts the torque of the hinge structure 130 back to the preset torque value.

[0048] Figure 2G is a schematic diagram of the internal structure of the electronic device in Figure 2D when it switches to the third mode. Figure 2H is a schematic diagram of the internal structure of the torque adjustment member in Figure 2G when it rotates back to its initial position. Referring to Figures 2D, 2G and 2H, after increasing the torque of the hinge structure 130, the user can drag the torque operation part 241 to slide along the first direction D1 parallel to the axis AX, so that the adjustment part 242, which slides synchronously with the operation part 241, separates from the hinge structure 230, thereby locking the torque of the hinge structure 130. That is, when the adjustment part 242 separates from the hinge structure 230, the torque of the hinge structure 230 does not change with the torque adjustment member 240 rotating along the second rotation direction R2 or the fourth rotation direction R4.

[0049] As shown in Figures 2G and 2H, after the torque of the hinge structure 230 is locked, the user can apply force to press down the operating part 241, causing the operating part 241 to rotate around the axis AX in the fourth rotation direction R4 towards the first body 210 to contact the first body 210. Then, the user can apply force to push the torque adjustment member 240 to slide in the second direction D2 opposite to the first direction D1, so that the operating part 241 moves back into the finger groove 211 and the adjustment part 242 re-engages with the hinge structure 230.

[0050] It should be noted that the state in which the adjusting part 242 re-engages with the hinge structure 230 can be referred to in FIG2B, but the torque of the hinge structure 230 shown in FIG2H has been adjusted to be greater than the torque of the hinge structure 230 shown in FIG2B.

[0051] As shown in Figures 2B to 2D, the first body 110 includes a first pivot portion 213 adjacent to the groove 212, and the second body 220 includes a second pivot portion 221 rotatably connected to the first pivot portion 213. Specifically, a portion of the hinge structure 230 is disposed within the first pivot portion 213, and the adjusting portion 242 is further inserted from the groove 212 into the first pivot portion 213 to engage with the hinge structure 230.

[0052] In this embodiment, the hinge structure 230 includes a first bracket 231, a rotating shaft 232, a second bracket 233, a washer assembly 234, and an adjusting nut 235. The first bracket 231 is fixed to the first body 210, wherein the rotating shaft 232 is fixed to the first bracket 231, and the axis AX passes through the rotating shaft 232. The second bracket 233 is fixed to the second body 220 and rotatably connected to the rotating shaft 232. The washer assembly 234 is disposed on the rotating shaft 232, and the adjusting nut 235 is screwed to the end of the rotating shaft 232.

[0053] The pivot 232 and the adjusting part 242 are coaxially configured, wherein the pivot 232 passes through the second pivot 221, and the end of the pivot 232 and the adjusting nut 235 are inserted into the first pivot 213. The shim set 234 is located in the first pivot 213, and the end of the adjusting part 242 inserted into the first pivot 213 is engaged with the adjusting nut 235. Furthermore, the shim set 234 is positioned between the adjusting nut 235 and the second bracket 233. The user can apply force to the operating part 241 to control the adjusting part 242 to rotate in the second rotation direction R2, so that the adjusting nut 235 is rotated by the adjusting part 242, causing the adjusting nut 235 to move closer to the shim set 234 on the pivot 232, and increasing the tightness of the shim set 234 and the frictional resistance between the shim set 234 and the second bracket 233, so as to achieve the effect of increasing the torque of the hinge structure 230.

[0054] In contrast, the user can apply force to press down the operating part 241 to control the adjustment part 242 to rotate in the fourth rotation direction R4, so that the adjustment nut 235 can be rotated by the adjustment part 242, so that the adjustment nut 235 moves away from the shim group 234 on the rotating shaft 232, and reduces the amount of tightening on the shim group 234 and the frictional resistance between the shim group 234 and the second bracket 233, so as to achieve the effect of reducing the torque of the hinge structure 230.

[0055] As shown in Figures 2C and 2D, the end of the first pivot portion 213 inserted into the adjusting portion 242 has an adjusting hole 242a that mates with the adjusting nut 235, and the adjusting hole 242a is detachably fitted onto the adjusting nut 235. For example, the adjusting hole 242a may be a hexagonal hole, and the adjusting nut 235 may be a hexagonal nut that mates with the hexagonal hole, but this is not a limitation.

[0056] In summary, depending on the actual usage, the user can adjust the torque of the hinge structure by rotating the torque adjustment component. Therefore, the electronic device of the present invention not only has excellent operational flexibility and convenience, but also meets the user's need for independent operation. Specifically, after adjusting the torque of the hinge structure to a value greater than the preset torque, it can prevent the second body from wobbling or accidentally falling due to insufficient positioning torque after unfolding relative to the first body.

[0057] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims. [Simplified Explanation of the Diagram]
