Description

Technical Field

[0001] The present invention relates to a rotating shaft structure, and in particular to a rotating shaft structure with a simple structure and convenient assembly and disassembly, and a rotating module and an electronic device equipped with the rotating shaft structure. Background Art

[0002] Currently, many electronic devices utilize hinges to pivotally connect a rotating module (e.g., a display, camera, support frame, door cover, etc.) to the device body. This allows the rotating module to be opened or closed by rotating the hinge relative to the device body, and the rotating module can be retained in a specific position relative to the device body by the torque generated by the hinge. Conventional hinges have complex structures, and the torque cannot be adjusted. Replacing the hinge is expensive, and users cannot easily disassemble and install the hinge.

[0003] Therefore, it is necessary to provide an electronic device, a rotating module, and a rotating shaft structure to solve the above problems. Summary of the Invention

[0004] The present invention provides a rotating shaft structure with a simple structure and convenient assembly and disassembly, and a rotating module and an electronic device equipped with the rotating shaft structure to solve the above problems.

[0005] According to one embodiment, an electronic device of the present invention includes a device body and a rotation module. The device body includes a first axial hole. The rotation module includes a first fixing structure and a first rotation axis structure. The first rotation axis structure includes at least one elastic arm, at least one protrusion, and a fixing portion. The at least one elastic arm and the fixing portion are located on opposite sides of the first rotation axis structure. The at least one protrusion extends from each of the at least one elastic arm. The fixing portion is fixed to the first fixing structure. The at least one elastic arm is disposed in the first axial hole. The at least one protrusion abuts against the inner wall of the first axial hole.

[0006] According to one embodiment, the rotation module of the present invention includes a first fixing structure and a first rotating shaft structure. The first rotating shaft structure includes at least one elastic arm, at least one protrusion, and a fixing portion. The at least one elastic arm and the fixing portion are located on opposite sides of the first rotating shaft structure. The at least one protrusion extends from each of the at least one elastic arm. The fixing portion is fixed to the first fixing structure.

[0007] According to another embodiment, the hinge structure of the present invention includes a base, a head, at least one elastic arm, at least one protrusion, and a fixed portion. The head is detachably connected to the base. The at least one elastic arm is located on the head. The at least one protrusion is located on the head and extends from each of the at least one elastic arm. The fixed portion is located on the base. The at least one elastic arm and the fixed portion are located on opposite sides of the hinge structure.

[0008] In summary, the hinge structure of the present invention primarily consists of an elastic arm, a protrusion, and a fixed portion, resulting in a relatively simple structure. Furthermore, the hinge structure is secured to the fixed structure of the rotation module via the fixed portion, making assembly and disassembly quite convenient. When the rotation module rotates relative to the device body, the hinge structure provides torque through the friction between the protrusion on the elastic arm and the axial hole in the device body, allowing the rotation module to remain in a specific position relative to the device body. Therefore, the present invention can adjust the torsional force of the hinge structure by varying the hinge structure's material, the thickness and width of the elastic arm, and / or the position of the protrusion, thereby making the hinge structure more flexible in use.

[0061] See also Figures 1 to 7 , Figure 1 is a three-dimensional diagram of an electronic device 1 according to an embodiment of the present invention, Figure 2 for Figure 1 A perspective view of the rotating module 12 opened relative to the device body 10, Figure 3 for Figure 2 The internal partial stereoscopic view of the device body 10, Figure 4 for Figure 3 The exploded view of the device body 10 and the rotating module 12, Figure 5 for Figure 4 The internal stereogram of the rotating module 12 in another perspective, Figure 6 for Figure 5 A partial exploded view of the rotation module 12, Figure 7 for Figure 6 A three-dimensional view of the first rotating shaft structure 124 at another viewing angle.

[0062] like Figure 1 and Figure 2 As shown, the electronic device 1 includes a device body 10 and a rotating module 12. The rotating module 12 is pivotally connected to the device body 10 so that the rotating module 12 can be rotated relative to the device body 10 to open or close. In this embodiment, the device body 10 may be an all-in-one (AIO) computer, and the rotating module 12 may be a camera. In another embodiment, the device body 10 may be a base of a notebook computer, and the rotating module 12 may be a display of the notebook computer. In another embodiment, the device body 10 may be a tablet computer, a smart phone or other mobile device, and the rotating module 12 may be a support frame. In another embodiment, the device body 10 may be the shell of any electronic device, and the rotating module 12 may be a door cover. It should be noted that the types of the device body 10 and the rotating module 12 may be determined according to actual applications and are not limited to the above-mentioned embodiments.

[0063] like Figure 3 and Figure 4 As shown, the device body 10 includes a first axial hole 100 and a second axial hole 102, wherein the first axial hole 100 is a circular hole and the second axial hole 102 is a C-shaped hole. The first axial hole 100 and the second axial hole 102 are arranged opposite each other. In this embodiment, the first axial hole 100 can be formed on a first axial seat 104 of the device body 10, and the second axial hole 102 can be formed on a second axial seat 106 of the device body 10.

[0064] like Figures 3 to 6 As shown, the rotation module 12 includes a first fixing structure 120, a first through hole 122, a first rotation axis structure 124, and a shaft portion 126. In this embodiment, the first fixing structure 120, the first through hole 122, and the shaft portion 126 can be integrally formed on the housing of the rotation module 12, wherein the first fixing structure 120 and the first through hole 122 are located on one side of the rotation module 12, and the shaft portion 126 is located on the other side of the rotation module 12.

[0065] The first rotating shaft structure 124 includes at least one elastic arm 1240, at least one protrusion 1242, and a fixing portion 1244, wherein the at least one elastic arm 1240 and the fixing portion 1244 are located on two opposite sides of the first rotating shaft structure 124, and the at least one protrusion 1242 extends from the at least one elastic arm 1240. In addition, the first rotating shaft structure 124 may further include at least one reinforcing rib 1246, wherein the at least one reinforcing rib 1246 extends from the bottom of the at least one elastic arm 1240, as shown in FIG. Figure 7As shown. In this embodiment, the first rotating shaft structure 124 may include four elastic arms 1240, four protrusions 1242 and four reinforcing ribs 1246, wherein each protrusion 1242 extends from one of the four elastic arms 1240, and each reinforcing rib 1246 extends from the bottom of one of the four elastic arms 1240. It should be noted that the number of elastic arms 1240, protrusions 1242 and reinforcing ribs 1246 can be determined according to actual application and is not limited to the embodiment shown in the figure. The reinforcing ribs 1246 can increase the moment of inertia of the elastic arm 1240 to increase the elastic force of the elastic arm 1240. If the elastic force of the elastic arm 1240 itself meets the requirements, the reinforcing ribs 1246 can be omitted.

[0066] The fixing portion 1244 of the first rotating shaft structure 124 passes through the first through hole 122 and is fixed to the first fixing structure 120. At this time, at least a portion of the first rotating shaft structure 124 is located in the first through hole 122, and the first through hole 122 is located between the protruding portion 1242 and the fixing portion 1244. In this embodiment, the fixing portion 1244 of the first rotating shaft structure 124 can be a through hole, and the first fixing structure 120 can be a screw hole. Therefore, Figure 5 and Figure 6 As shown, the present invention can utilize the screw 30 to pass through the fixing portion 1244 and be locked to the first fixing structure 120 , so that the fixing portion 1244 of the first rotating shaft structure 124 is fixed to the first fixing structure 120 .

[0067] In this embodiment, the first through-hole 122 may include a positioning rib 1220, and the first rotating shaft structure 124 may include a positioning groove 1248. The positioning groove 1248 of the first rotating shaft structure 124 is located between the elastic arm 1240 and the fixing portion 1244. When the fixing portion 1244 of the first rotating shaft structure 124 passes through the first through-hole 122, the positioning rib 1220 aligns with and enters the positioning groove 1248. The positioning rib 1220 and the positioning groove 1248 cooperate to position the first rotating shaft structure 124 in the first through-hole 122. In another embodiment, the first through-hole 122 may also include a positioning groove 1248, and the first rotating shaft structure 124 may also include a positioning rib 1220. In this case, the positioning rib 1220 is located between the elastic arm 1240 and the fixing portion 1244. In other words, one of the first hinge structure 124 and the first through hole 122 may include a positioning rib 1220, and the other of the first hinge structure 124 and the first through hole 122 may include a positioning groove 1248, depending on the actual application. Furthermore, the number of positioning ribs 1220 and positioning grooves 1248 may be one or more sets, also depending on the actual application. In another embodiment, the positioning ribs 1220 and positioning grooves 1248 may be omitted.

[0068] After the fixing portion 1244 of the first rotating shaft structure 124 is fixed to the first fixing structure 120, the first rotating shaft structure 124 and the shaft portion 126 are located on opposite sides of the rotating module 12. When assembling the rotating module 12 to the device body 10, the user can first insert the elastic arm 1240 of the first rotating shaft structure 124 into the first shaft hole 100. Then, the user can place the shaft portion 126 of the first rotating shaft structure 124 into the second shaft hole 102. When removing the rotating module 12 from the device body 10, the user can first remove the shaft portion 126 of the first rotating shaft structure 124 from the second shaft hole 102. Then, the user can pull the elastic arm 1240 of the first rotating shaft structure 124 out of the first shaft hole 100. Therefore, the rotating module 12 of the present invention is very convenient to assemble and disassemble.

[0069] After the rotating module 12 is assembled to the device body 10, the elastic arm 1240 of the first rotating shaft structure 124 is disposed in the first shaft hole 100, and the protrusion 1242 on the elastic arm 1240 abuts against the inner wall of the first shaft hole 100. Figure 3 As shown. At the same time, the shaft portion 126 is disposed in the second shaft hole 102. When the rotation module 12 rotates relative to the device body 10, the rotation shaft structure 12 will provide a torque by means of the friction between the protrusion 1242 on the elastic arm 1240 and the first shaft hole 100 of the device body 10, so that the rotation module 12 can stay in a specific position relative to the device body 10. The first rotation shaft structure 124 of the present invention is mainly composed of the elastic arm 1240, the protrusion 1242 and the fixing portion 1244, and the structure is quite simple. In addition, the present invention can adjust the torsional force of the first rotation shaft structure 124 by changing the material of the first rotation shaft structure 124, the thickness and width of the elastic arm 1240, and / or the position of the protrusion 1242, so that the first rotation shaft structure 124 is more flexible in use.

[0070] See also Figure 8 as well as Figure 9 , Figure 8 is a partial internal perspective view of an electronic device 1' according to another embodiment of the present invention. Figure 9 for Figure 8 Exploded view of the electronic device 1'.

[0071] The main difference between the electronic device 1' and the above-mentioned electronic device 1 is that the device body 10 of the electronic device 1' further includes a second shaft hole 102', and the rotation module 12 of the electronic device 1' further includes a second fixing structure 120', a second through hole 122' and a second rotating shaft structure 124'. Figure 8 and Figure 9As shown. In this embodiment, the configuration of the second axis hole 102', the second fixing structure 120', the second through hole 122' and the second rotating shaft structure 124' is the same as the configuration of the first axis hole 102, the first fixing structure 120, the first through hole 122 and the first rotating shaft structure 124 described above, and the first rotating shaft structure 124 and the second rotating shaft structure 124' are located on opposite sides of the rotating module 12. The present invention can utilize another screw 30' to fix the second rotating shaft structure 124' to the second fixing structure 120'. In other words, the electronic device 1' can replace the second axis hole 102 and the shaft portion 126 of the electronic device 1 with the second axis hole 102', the second fixing structure 120', the second through hole 122' and the second rotating shaft structure 124'. The working principle of the second rotating shaft structure 124' is the same as that of the above-mentioned first rotating shaft structure 124, which will not be repeated here.

[0072] See also Figure 10 as well as Figure 11 , Figure 10 This is an internal perspective view of a rotation module 12' according to another embodiment of the present invention. Figure 11 for Figure 10 A partial exploded view of the rotation module 12'.

[0073] The main difference between the rotating module 12' and the rotating module 12 mentioned above is that the fixing portion 1244 of the first rotating shaft structure 124 of the rotating module 12' is a slot, and the first fixing structure 120 of the rotating module 12' is a protruding column. Figure 10 and Figure 11 Therefore, the fixing portion 1244 of the first rotating shaft structure 124 can be engaged with the first fixing structure 120 , so that the fixing portion 1244 of the first rotating shaft structure 124 is fixed to the first fixing structure 120 .

[0074] In another embodiment, Figure 8 and Figure 9 The second fixing structure 120' and the second rotating shaft structure 124' can also be Figure 10 and Figure 11 The first fixing structure 120 is replaced with the first rotating shaft structure 124.

[0075] See also Figures 12 to 16 , Figure 12 This is a three-dimensional diagram of a first rotating shaft structure 124" according to another embodiment of the present invention. Figure 13 for Figure 12 An exploded view of the first rotating shaft structure 124" is shown in FIG. Figure 14 for Figure 12 A stereoscopic view of the head 1252 in another perspective, Figure 15 for Figure 12 A cross-sectional view of the first rotating shaft structure 124" is shown in FIG. Figure 16 for Figure 15 A cross-sectional view of the limiting member 1254 after being pressed.

[0076] The main difference between the first rotating shaft structure 124 ″ and the above-mentioned first rotating shaft structure 124 is that the first rotating shaft structure 124 ″ further includes a base 1250 , a head 1252 , a stopper 1254 and an elastic member 1256 , such as Figures 12 to 16 As shown. The above-mentioned fixing portion 1244 and positioning groove 1248 can be located on the base 1250, and the above-mentioned elastic arm 1240 and protrusion 1242 can be located on the head 1252. In this embodiment, the head 1252 can be detachably connected to the base 1250. For example, the base 1250 can include an external thread 1258, and the head 1252 can include an internal thread 1260. The internal thread 1260 can be screwed with the external thread 1258, so that the head 1252 can be detachably connected to the base 1250. Furthermore, the user can rotate the head 1252 so that the head 1252 moves relative to the base 1250 through the cooperation between the internal thread 1260 and the external thread 1258. In this way, the user can remove the head 1252 from the base 1250 or assemble the head 1252 to the base 1250.

[0077] In addition, the base 1250 may include a receiving groove 1262, the head 1252 may include a limiting hole 1264, and the limiting member 1254 may include a limiting portion 1266. Figure 15 As shown, the limiting member 1254 is movably disposed in the accommodating groove 1262, and the limiting portion 1266 is engaged with the limiting hole 1264. In addition, the elastic member 1256 is disposed in the accommodating groove 1262, and the two opposite ends of the elastic member 1256 abut against the limiting member 1254 and the base 1250. In this embodiment, the elastic member 1256 can be a spring, but is not limited to this. After the first rotating shaft structure 124" is assembled, the elastic member 1256 will push the limiting member 1254 toward the limiting hole 1264, so that the limiting portion 1266 is engaged with the limiting hole 1264. Thereby, the head 1252 can be prevented from rotating relative to the base 1250. When the user wants to rotate the head 1252 to move the head 1252 relative to the base 1250, the user can first press the limiting portion 1266 to disengage the limiting portion 1266 from the limiting hole 1264, as shown in FIG. Figure 16 Then, the user can rotate the head 1252 to move the head 1252 relative to the base 1250.

[0078] See also Figure 17 , Figure 17 for Figure 16 Schematic diagram of the first rotating shaft structure 124" being arranged in the first shaft hole 100. Figure 17As shown, the diameter of the first shaft hole 100 is fixed. When the torque of the first rotating shaft structure 124″ decreases due to wear of the first shaft hole 100, the user can rotate the head 1252 so that the head 1252 moves relative to the base 1250 in the direction of arrow A1 or A2 to adjust the contact position between the protrusion 1242 and the first shaft hole 100. In this way, the torque of the first rotating shaft structure 124″ can be restored.

[0079] See also Figure 18 , Figure 18 for Figure 16 Another schematic diagram of the first rotating shaft structure 124" being disposed in the first shaft hole 100. Figure 18 As shown, the diameter of the first shaft hole 100 decreases from the base 1250 toward the head 1252. The user can rotate the head 1252 so that the head 1252 moves relative to the base 1250 in the direction of arrow A1 to increase the elastic deformation of the elastic arm 1240. This can increase the rotational friction and thereby increase the torque of the first rotating shaft structure 124". On the other hand, the user can rotate the head 1252 so that the head 1252 moves relative to the base 1250 in the direction of arrow A2 to reduce the elastic deformation of the elastic arm 1240. This can reduce the rotational friction and thereby reduce the torque of the first rotating shaft structure 124". In other words, when the head 1252 moves relative to the base 1250, the elastic deformation of the elastic arm 1240 will change with the change in the diameter of the first shaft hole 100 to adjust the torque of the first rotating shaft structure 124".

[0080] See also Figure 19 , Figure 19 for Figure 16 Another schematic diagram of the first rotating shaft structure 124" being disposed in the first shaft hole 100. Figure 19 As shown, the diameter of the first shaft hole 100 increases from the base 1250 toward the head 1252. The user can rotate the head 1252 so that the head 1252 moves relative to the base 1250 in the direction of arrow A1 to reduce the elastic deformation of the elastic arm 1240. In this way, the rotational friction can be reduced, thereby reducing the torque of the first rotating shaft structure 124". On the other hand, the user can rotate the head 1252 so that the head 1252 moves relative to the base 1250 in the direction of arrow A2 to increase the elastic deformation of the elastic arm 1240. In this way, the rotational friction can be increased, thereby increasing the torque of the first rotating shaft structure 124". In other words, when the head 1252 moves relative to the base 1250, the elastic deformation of the elastic arm 1240 will change with the change in the diameter of the first shaft hole 100 to adjust the torque of the first rotating shaft structure 124".

[0081] The first rotating shaft structure 124 and the second rotating shaft structure 124' can be replaced by the first rotating shaft structure 124", and the apertures of the first shaft hole 100 and the second shaft hole 102' can be designed according to the actual application. Figures 17 to 19 When the contact point of the head 1252 of the first rotating shaft structure 124″ with the first rotating shaft hole 100 is worn, the user can rotate the head 1252 to remove the head 1252 from the base 1250. Then, the user can assemble another new head 1252 onto the base 1250 and adjust the torque of the first rotating shaft structure 124″ according to the above method.

[0082] In summary, the hinge structure of the present invention primarily consists of an elastic arm, a protrusion, and a fixed portion, resulting in a relatively simple structure. Furthermore, the hinge structure is secured to the fixed structure of the rotation module via the fixed portion, making assembly and disassembly quite convenient. When the rotation module rotates relative to the device body, the hinge structure provides torque through the friction between the protrusion on the elastic arm and the axial hole in the device body, allowing the rotation module to remain in a specific position relative to the device body. Therefore, the present invention can adjust the torsional force of the hinge structure by varying the hinge structure's material, the thickness and width of the elastic arm, and / or the position of the protrusion, thereby making the hinge structure more flexible in use.
