Technical Field

[0001] This invention relates to the field of electronic devices, and more particularly to a hinge structure, electronic devices, and a method for assembling cables on the hinge structure. Background Technology

[0002] With the continuous advancement of technology, laptops have become essential tools in people's daily lives, serving as the primary electronic device. The laptop screen and motherboard are opened and closed via hinges located at the edges. Traditional hinges are typically raised, recessed, or multi-hinge types. These traditional hinges achieve opening and closing through direct friction, resulting in the screen not being able to be stably fixed at any angle. Alternatively, increasing friction to achieve stable screen fixation at any angle requires more effort from the user, leading to a poor user experience.

[0003] Therefore, it is necessary to provide a new method for assembling a hinge structure, electronic devices, and cables on a hinge structure to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a method for assembling a hinge structure, electronic equipment, and cables on a hinge structure to optimize the interlocking force when the first body and the second body are opened and closed.

[0011] The rotating shaft structure also includes a cable that passes through the first channel, and the cable, rotating shaft module and bracket are combined into one unit.

[0012] The bracket includes a body and mounting holes disposed at opposite ends of the body. One end of the drive shaft has an anti-slip texture, which is inserted into the mounting hole, while the damping texture protrudes outside the mounting hole.

[0013] As a further improvement of the present invention, the damping texture portion is provided with a plurality of damping textures, and the plurality of damping textures are arranged around the outer wall of the transmission shaft in the circumferential direction.

[0014] As a further improvement of the present invention, two adjacent damping patterns have a gap in the axial direction of the transmission shaft, and the formula for calculating the distance of the gap is:

[0015] The distance of the gap = weight of the second body / minimum self-locking opening and closing angle between the first body and the second body * 100%.

[0016] As a further improvement of the present invention, the bracket further includes a positioning part, which is disposed on one side of the main body and configured to be fixedly connected to the first body.

[0017] As a further improved technical solution of the present invention, the transmission base has a tube and a fixing part disposed on the side wall of the tube. The tube is sleeved on the outside of the damping texture, the inner wall of the tube is in contact with the damping texture, and the fixing part is configured to be connected to the second body.

[0041] This invention discloses an electronic device comprising a first body and a second body, wherein the first body and the second body constitute a foldable electronic device. The electronic device also includes a hinge structure 100, through which opposite sides of the first body and the second body are pivotally connected. In embodiments of the application, the electronic device includes, but is not limited to, a laptop computer, where the first body is, for example, a system unit, the second body is, for example, a screen, and the hinge structure 100 allows the first body and the second body to open and close relative to each other. A detailed description follows.

[0042] Please refer to Figure 1 The hinge structure 100 also includes a cable 200, which has high-speed signal transmission capabilities. The first end 202 of the cable 200 has a CPU contact terminal, which is electrically connected to the CPU in the first housing. The second end 203 of the cable 200 has an integrated terminal for a display screen, touchscreen, camera, and sensors, and is electrically connected to a display module in the second housing. In embodiments of this application, the cable 200 includes, but is not limited to, electronic wires and coaxial cables. The cable 200 is externally covered with insulating or conductive materials to improve its protection and shielding capabilities.

[0043] Please refer to Figures 1 to 10 The rotating shaft structure 100 includes a bracket 1 and a rotating shaft module 2. The bracket 1 is used to be installed at the edge of the first body. One end of the rotating shaft module 2 is connected to the bracket 1, and the other end of the rotating shaft module 2 is connected to the second body.

[0044] Please refer to Figures 1 to 2 as well as Figure 7 The bracket 1 is generally elongated and extends along a first direction AA. The first direction AA is consistent with the edge extension direction of the first body. The bracket 1 includes a body 11 and mounting holes 12 disposed at opposite ends of the body 11 along the first direction AA. One end of the rotating shaft module 2 is fixed in the mounting hole 12. In the embodiment of this application, the body 11 is mounted at the edge of the first body. The bracket 1 also includes a positioning part 13, which is disposed on one side of the body 11 and configured to be fixedly connected to the first body. Specifically, the positioning part 13 protrudes towards one side of the first body and has a plurality of positioning holes 131. The first body is fixedly connected to the positioning holes 131 by screws, thereby enabling the bracket 1 to be fixed to the first body. The body 11 also has a plurality of snap-fit ​​parts 14, which are disposed opposite to the positioning part 13 and snap-fit ​​connected to the edge of the first body. The main body 11 has a mounting groove 101, the first body is connected to the mounting groove 101, and the mounting hole 12 is connected to the mounting groove 101. Therefore, the cable 200 can enter the second body through the mounting hole 12 and the mounting groove 101. Preferably, the bracket 1 is integrally formed, thereby ensuring the appearance quality of the bracket 1.

[0045] Please refer to Figures 1 to 3 The rotating shaft module 2 includes two rotating shaft assemblies 21. The two opposite ends of the rotating shaft assembly 21 are mounted on the two ends of the bracket 1, and the opposite ends of the rotating shaft assembly 21 are respectively used to connect with the second body.

[0046] Please refer to Figures 2 to 6 The rotating shaft assembly 21 includes a drive shaft 211 and a drive base 212. The drive shaft 211 has a first channel 201 that passes through opposite ends of the drive shaft 211. A cable 200 passes through the first channel 201. The cable 200, the rotating shaft module 2, and the bracket 1 are integrated into one unit. The drive shaft 211 has a first end and a second end that are arranged opposite to each other. The first end of the drive shaft 211 is connected to the bracket 1. The drive base 212 is sleeved on the outer wall of the second end of the drive shaft 211 and is pivotally connected to the drive shaft 211.

[0047] Please refer to Figure 4 as well as Figure 6 The outer wall of the second end of the drive shaft 211 has a damping groove 2111, which contacts the inner wall of the drive base 212. The damping groove 2111 protrudes towards the inner wall of the drive base 212. When the drive base 212 and the drive shaft 211 pivot, the damping groove 2111 can optimize the engagement force between the drive base 212 and the drive shaft 211, thereby improving the user experience when the first and second bodies open and close.

[0048] In the embodiment illustrated in the present invention, the damping texture portion 2111 is provided with multiple damping textures, which are arranged circumferentially around the outer wall of the drive shaft 211. Adjacent damping textures have a gap in the axial direction of the drive shaft 211. In one embodiment, the multiple damping textures are spirally arranged around the outer wall of the drive shaft 211, connected end-to-end. In another embodiment, the multiple damping textures are annularly arranged around the outer wall of the drive shaft 211, and each damping texture is parallel to the others. Both the first and second embodiments optimize the engagement force between the transmission base 212 and the drive shaft 211 during pivoting.

[0049] The formula for calculating the distance between two adjacent damping grooves is:

[0050] The gap distance = weight of the second unit / minimum self-locking opening and closing angle between the first and second units * 100%.

[0051] In the embodiments of this application, the minimum self-locking opening and closing angle between the first body and the second body is 15° to 30°. When the opening and closing angle between the first body and the second body is 15° to 30°, the first body and the second body will slowly close to achieve the self-locking function, thereby providing a better user experience.

[0052] Preferably, in the first direction AA, the total length of the multiple damping grooves is 2 / 3 of the length of the drive shaft 211. By calculating the spacing and length of the damping grooves, the stability of the first and second bodies is improved during opening and closing.

[0053] Please refer to Figures 2 to 5 The transmission base 212 has a tube 2121 and a fixing part 2122 disposed on the side wall of the tube 2121. The fixing part 2122 is configured to connect with the second body. Specifically, the tube 2121 is hollow and is sleeved on the outside of the damping groove part 2111. The inner wall of the tube 2121 contacts the damping groove part 2111. The damping groove part 2111 can optimize the meshing force between the transmission shaft 211 and the transmission base 212 during pivoting, thereby improving the user experience.

[0054] Please refer to Figures 5 to 6 The fixing part 2122 has a protrusion 21221, which is provided at one end of the fixing part 2122 facing the drive shaft 211 and protrudes from the tube part 2121. Specifically, the protrusion 21221 extends toward the drive shaft 211 along the axial direction of the tube part 2121. When the drive shaft 211 is assembled with the drive base 212, the fixing part 2122 rotates around the circumference of the drive shaft 211. At this time, the protrusion 21221 of the fixing part 2122 can cooperate with the drive shaft 211 to restrict the rotation of the drive base 212 within a fixed angle, thereby limiting the opening and closing of the second body and the first body within the maximum angle.

[0055] Please refer to Figures 2 to 6 The outer wall of the first end of the drive shaft 211 has an anti-slip textured portion 2112, which is integrally formed with the damping textured portion 2111. The anti-slip textured portion 2112 is inserted into the mounting hole 12. Specifically, the anti-slip textured portion 2112 makes frictional contact with the inner wall of the mounting hole 12 to restrict the rotation of the drive shaft 211 within the mounting hole 12, thereby fixing the drive shaft 211 to the bracket 1.

[0056] Please refer to Figures 5 to 6The drive shaft 211 has a stop portion 2113, which is located on the side of the damping texture portion 2111 away from the tube portion 2121. The protrusion 21221 can contact the stop portion 2113 during rotation. Specifically, the stop portion 2113 is located between the damping texture portion 2111 and the anti-slip texture portion 2112. The stop portion 2113 is arc-shaped and is arranged circumferentially along the drive shaft 211. The stop portion 2113 has a first stop portion 21131 and a second stop portion 21132, which are located at opposite ends of the arc of the stop portion 2113. When the transmission base 212 rotates circumferentially around the transmission shaft 211, the upper and lower surfaces of the protrusion 21221 can respectively make rotational contact with the first stop 21131 and the second stop 21132, thereby restricting the protrusion 21221 of the transmission base 212 from rotating within the arc-shaped notch formed by the first stop 21131 and the second stop 21132. The arc-shaped notch of the first stop 21131 and the second stop 21132 is consistent with the maximum opening and closing angle of the first body and the second body.

[0057] Please refer to Figure 1 as well as Figures 7 to 10 The shaft structure 100 also includes several washers 3, which are fitted onto the cable 200. One of the washers 3 elastically abuts against the side edge of the damping texture 2111, and another washer 3 elastically abuts against the side edge of the mounting hole 12. The washers 3 can reinforce the cable 200 so that it will not move between the shaft assembly 21 and the bracket 1, thereby improving assembly efficiency.

[0058] The present invention also discloses an assembly method for a rotating shaft structure 100, comprising the following steps:

[0059] The transmission base 212 is fitted onto the damping texture 2111 of the transmission shaft 211;

[0060] The anti-slip textured parts 2112 of the two drive shafts 211 are respectively installed in the mounting holes 12 at opposite ends of the bracket 1;

[0061] The transmission base 212 is fitted onto the damping texture 2111 of the transmission shaft 211, or the anti-slip texture 2112 of the two transmission shafts 211 are respectively installed into the mounting holes 12 at opposite ends of the bracket 1. The order of the above installation steps is not limited in this application.

[0062] Cable 200 passes through the first channel 201.

[0063] In the first assembly method, the second end 203 of the cable 200 is first welded to the display module inside the second housing. After the welded cable 200 is covered with insulating material, the first washer 3 is fitted over the insulation layer of the cable 200 from the first end 202. The first end 202 of the cable 200 passes through the tube 2121 away from the drive shaft 211 along the first channel 201 towards the mounting hole 12. Then, the second washer 3 is fitted over the insulation layer of the cable 200 from the second end 203. The position of the cable 200 is adjusted so that the first washer 3 is adjusted to elastically abut against the outer wall of the tube 2121, and the second washer 3 is adjusted to elastically abut against the outer wall of the mounting hole 12. This positions the cable 200 within the first channel 201, preventing the cable 200 from moving within the first channel 201 during assembly and affecting assembly efficiency. Finally, the first end 202 of the cable 200 enters the first housing through the mounting slot 101 and is soldered to the CPU in the first housing to complete the assembly of the shaft structure 100 on the electronic device.

[0064] In the second assembly method, the first end 202 of the cable 200 is soldered to the CPU inside the first housing. After the soldered cable 200 is covered with insulating material, the first washer 3 is placed over the insulation layer of the cable 200. The second end 203 of the cable 200 passes through the mounting groove 101 and the mounting hole 12 from the first channel 201, exiting from the side of the tube 2121 away from the drive shaft 211. The second washer 3 is then placed over the insulation layer of the cable 200 from the second end 203 of the cable 200. The position of the cable 200 is adjusted so that the first washer 3 is adjusted to elastically abut against the outer wall of the mounting hole 12, and the second washer 3 is adjusted to elastically abut against the outer wall of the tube 2121. This positions the cable 200 within the first channel 201, preventing the cable 200 from moving within the first channel 201 during assembly and affecting assembly efficiency. Finally, the second end 203 of the cable 200 is soldered to the display module inside the second body to complete the assembly of the hinge structure 100 on the electronic device.

[0065] The above two assembly methods allow the cable 200 to pass through the transmission base 212, the transmission shaft 211, and the mounting hole 12 of the bracket 1, so that the cable 200, the transmission base 212, the transmission shaft 211, and the bracket 1 form an integrated structure. This makes assembly more convenient and simple, reduces production costs, and also makes the overall structure of the electronic device thinner and lighter.

[0066] In summary, the rotating shaft structure 100 of the present invention includes a bracket 1 and a rotating shaft module 2. The bracket 1 is installed at the edge of the first body. The rotating shaft module 2 includes two rotating shaft assemblies 21. The two opposing ends of the rotating shaft assemblies 21 are installed at both ends of the bracket 1, and the two opposing ends of the rotating shaft assemblies 21 are respectively used to connect to the second body. The rotating shaft assembly 21 includes a drive shaft 211 and a drive base 212. One end of the drive shaft 211 is fixedly connected to the bracket 1, and the drive base 212 is sleeved on the outer wall of the other end of the drive shaft 211 and pivotally connected to the drive shaft 211. The drive shaft 211 has a first channel 201 that passes through the opposite ends of the drive shaft 211 for the cable 200 to pass through. By providing a damping texture 2111 on the outer wall of the drive shaft 211, the engagement force between the drive shaft 211 and the drive base 212 is increased when the drive base 212 pivots around the drive shaft 211, thereby improving the user experience.

[0067] The above embodiments are for illustrative purposes only and are not intended to limit the technical solutions described in this invention. The understanding of this specification should be based on those skilled in the art. For example, the directional descriptions such as "front," "back," "left," "right," "up," and "down" are important. Although this specification has described the invention in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify or make equivalent substitutions to this invention. All technical solutions and improvements that do not depart from the spirit and scope of this invention should be covered within the scope of the claims of this invention.
