Description

Technical Field

[0001] This disclosure relates to the field of electronic technology, and in particular to a rotating shaft assembly and an electronic device. Background Technology

[0002] With the rapid development of the consumer electronics industry, users have increasingly higher demands for the portability and ergonomic features of electronic products, and laptops have begun to develop in the direction of becoming thinner and lighter.

[0003] Traditional laptop hinges have a fixed pivot point, meaning the relative distance between the screen and the main unit remains constant when the screen is flipped open. This places the opened screen on the side of the main unit furthest from the user, increasing the distance between the screen and the user, making the laptop occupy more space, and negatively impacting the user experience. Utility Model Content

[0004] In view of this, the present disclosure provides a hinge assembly and an electronic device that can reduce the distance between the screen and the user.

[0005] Specifically, the following technical solutions are included: In a first aspect, embodiments of this disclosure provide a rotating shaft assembly, including a first shaft, a second shaft, a first slider, a first fixing member, and a second fixing member. The first shaft is fixedly connected to the first fixing member, the first slider is located on a first surface of the second fixing member and slides with the second fixing member, and the first shaft and the second shaft are rotatably connected to the first slider. A first gear is provided on the first shaft, a second gear is provided on the second shaft, and a rack is provided on the first surface of the second fixing member. The first gear meshes with the second gear, and the second gear meshes with the rack.

[0006] In some embodiments of this disclosure, a slide rail is provided on the second surface of the second fixing member, the second surface being adjacent to the first surface, and a slide groove is provided on the first slider, with the slide rail slidably engaging with the slide groove. The first slider can slide along the slide rail on the second fixing member, thereby changing the relative position of the first shaft and the second fixing member.

[0007] In some embodiments of this disclosure, the shaft assembly further includes a second slider connected to one side of the first slider, and a receiving space is formed between the first and second sliders, within which the first gear and the second gear are located. The receiving space can provide protection for the first and second gears and contain lubricant applied to the first and second gears.

[0008] In some embodiments of this disclosure, the rotating shaft assembly further includes a guide post. A guide hole is provided at one end of the second slider near the first surface. The guide post is connected to the first surface of the second fixing member, passes through the guide hole, and slidably engages with the guide hole. This slidable engagement between the guide post and the guide hole restricts the movement direction of the second slider, thereby increasing the stability of the rotating shaft assembly during movement.

[0009] In some embodiments of this disclosure, the first surface of the second fixing member is provided with a receiving groove, and the two ends of the guide post are respectively connected to the inner walls of opposite sides of the receiving groove, with the second slider portion located within the receiving groove. The receiving groove can accommodate a portion of the second slider, thereby reducing the height of the second slider and helping to reduce the space occupied by the rotating shaft assembly.

[0010] In some embodiments of this disclosure, the rotating shaft assembly further includes a connecting piece located on the side of the second slider away from the first slider. The connecting piece is provided with a first connecting hole and a second connecting hole. One end of the first shaft passes through the second slider and the first connecting hole in sequence, and one end of the second shaft passes through the second slider and the second connecting hole in sequence. The connecting piece is used to limit the relative position of the first rotating shaft and the second rotating shaft.

[0011] In some embodiments of this disclosure, the shaft assembly further includes a first torque structure sleeved on one end of the first shaft. The first torque structure provides resistance when the first shaft rotates and keeps the first fixing member and the second fixing member relatively stationary when no external force is applied to the first fixing member.

[0012] In some embodiments of this disclosure, the shaft assembly further includes a second torque structure sleeved on one end of the second shaft. The second torque structure provides resistance to rotation of the second shaft and keeps the first and second fixing members relatively stationary when no external force is applied to the first fixing member.

[0013] In some embodiments of this disclosure, a clearance groove is provided on the first surface of the second fastener, and the second torsional structure portion is located within the clearance groove. The clearance groove is used to accommodate the second torsional structure, preventing interference between the second torsional structure and the second fastener.

[0014] In some embodiments of this disclosure, the first fastener is provided with at least one first mounting hole; and / or The second fastener is provided with at least one second mounting hole. The first mounting hole is used to fix the first fastener to the screen portion of the electronic device, and the second mounting hole is used to fix the second fastener to the main unit portion of the electronic device.

Detailed Implementation

[0022] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0023] Figure 1 An exploded view of the rotating shaft assembly provided in the embodiments of this disclosure; Figure 2 This is a schematic diagram of a rotating shaft assembly provided in an embodiment of this disclosure. Figure 1-2 As shown, the rotating shaft assembly provided in this embodiment includes a first shaft 1, a second shaft 2, a first slider 3, a first fixing member 5, and a second fixing member 6. The first shaft 1 is fixedly connected to the first fixing member 5. The first slider 3 is located on the first surface 601 of the second fixing member 6 and slides with the second fixing member 6. The first shaft 1 and the second shaft 2 are rotatably connected to the first slider 3. A first gear 101 is provided on the first shaft 1, a second gear 201 is provided on the second shaft 2, and a rack 602 is provided on the first surface 601 of the second fixing member 6. The first gear 101 meshes with the second gear 201, and the second gear 201 meshes with the rack 602.

[0024] In the rotating shaft assembly provided in this embodiment, the first fixing member 5 and the second fixing member 6 are respectively used to connect the screen part and the host part of the electronic device. When the first fixing member 5 rotates away from the second fixing member 6, the first fixing member 6 is transmitted to the second fixing member 6 through the first gear 101, the second gear 201 and the rack 602, so that the first fixing member 4 moves to the side facing the screen part during the rotation, thereby reducing the distance between the screen part and the user, saving the space occupied by the screen part, and improving the user experience.

[0025] To make the technical solutions and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, the rotating shaft assembly provided in this embodiment includes a first shaft 1, a second shaft 2, a first slider 3, a first fixing member 5, and a second fixing member 6. One end of the first shaft 1 is fixedly connected to the first fixing member 5. The first shaft 1, the second shaft 2, the first slider 3, and the first fixing member 5 are located on the side near the first surface 601 of the second fixing member 6. The first slider 3 is slidably engaged with the second fixing member 6, and the first shaft 1 and the second shaft 2 are rotatably connected to the first slider 3. A first gear 101 is provided on the first shaft 1, a second gear 201 is provided on the second shaft 2, and a rack 602 is provided on the first surface 601 of the second fixing member 6. The first gear 101 meshes with the second gear 201, and the second gear 201 meshes with the rack 602. The first fixing member 5 is used to connect to the screen part of the electronic device, the second fixing member 6 is used to connect to the host part of the electronic device, and the first slider 3 is used to limit the first shaft 1 and the second shaft 2 so that the distance between the first shaft 1 and the second shaft 2 is kept consistent, thereby making the first gear 101 and the second gear 201 mesh stably.

[0027] In some embodiments of this disclosure, such as Figure 1 As shown, the second surface 603 of the second fixing member 6 is provided with a slide rail 604, and the second surface 603 is adjacent to the first surface 601. The first slider 3 is provided with a slide groove 301, and the slide rail 604 is slidably engaged with the slide groove 301. The length direction of the slide groove 301 and the slide rail 604 is parallel to the length direction of the rack 602. When the second gear 201 rolls relative to the rack 602, the relative position of the first shaft 1 and the first slider 3 is fixed, and the first slider 3 can slide along the slide rail 604 on the second fixing member 6, thereby changing the relative position of the first shaft 1 and the second fixing member 6.

[0028] In some embodiments of this disclosure, such as Figure 1-2As shown, the rotating shaft assembly also includes a second slider 4, which is connected to one side of the first slider 3. A receiving space 400 is formed between the first slider 3 and the second slider 4, and the first gear 101 and the second gear 201 are located within the receiving space 400. The first slider 3 and the second slider 4 together serve to receive the first gear 101 and the second gear 201, providing protection for the first gear 101 and the second gear 201, and containing the lubricant coated on the first gear 101 and the second gear 201.

[0029] For example, the first slider 3 rolls with the first shaft 1 and the second shaft 2, and the second slider 4 rolls with the first shaft 1 and the second shaft 2, which can provide support for the first shaft 1 and the second shaft 2 and ensure stable meshing between the first gear 101 and the second gear 201.

[0030] Optionally, see Figure 1 The rotating shaft assembly also includes bolts 11, which can be two bolts, for fixing the first slider 3 and the second slider 4 together.

[0031] In some embodiments of this disclosure, such as Figure 1 As shown, the rotating shaft assembly also includes a guide post 7. A guide hole 401 is provided at one end of the second slider 4 near the first surface 601. The guide post 7 is connected to the first surface 601 of the second fixing member 6, passes through the guide hole 401, and slides in cooperation with the guide hole 401. This sliding cooperation between the guide post 7 and the guide hole 401 restricts the movement direction of the second slider 4, thereby increasing the stability of the rotating shaft assembly during movement.

[0032] Optionally, see Figure 1 The first surface 601 of the second fixing member 6 is provided with a receiving groove 605. The two ends of the guide post 7 are respectively connected to the inner walls of the opposite sides of the receiving groove 605. The second slider 4 is partially located in the receiving groove 605. The receiving groove 605 can accommodate part of the second slider 4, thereby reducing the height of the second slider 4 and helping to reduce the space occupied by the rotating shaft assembly.

[0033] For example, one end of the receiving groove 605 is provided with a threaded hole and the other end is provided with a through hole. One end of the guide post 7 is provided with an external thread. The end of the guide post 7 with the external thread passes through the through hole into the receiving groove 605 and is connected to the threaded hole at the other end of the receiving groove 605.

[0034] Figure 3 This is a partial schematic diagram of a rotating shaft assembly provided in an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 1-3As shown, the rotating shaft assembly also includes a connecting piece 8, which is located on the side of the second slider 4 away from the first slider 3. The connecting piece 8 has a first connecting hole 801 and a second connecting hole 802. One end of the first shaft 1 passes through the second slider 4 and the first connecting hole 801 in sequence, and one end of the second shaft 2 passes through the second slider 4 and the second connecting hole 802 in sequence. The connecting piece 8 is used to limit the relative position of the first shaft 1 and the second shaft 2, allowing the first shaft 1 and the second shaft 2 to rotate relative to the connecting piece 8.

[0035] In some embodiments of this disclosure, such as Figure 1-2 As shown, the rotating shaft assembly also includes a first torque structure 9, which is sleeved on one end of the first shaft 1. The first torque structure 9 is used to provide resistance when the first shaft 1 rotates, and to keep the first fixing member 5 and the second fixing member 6 relatively stationary when no external force is applied to the first fixing member 5.

[0036] The rotating shaft assembly also includes a second torque structure 10, which is sleeved on one end of the second shaft 2. The second torque structure 10 provides resistance to the rotation of the second shaft 2 and keeps the first fixing member 5 and the second fixing member 6 relatively stationary when no external force is applied to the first fixing member 5.

[0037] Optionally, see Figure 2 The first surface 601 of the second fastener 6 is provided with a relief groove 606, and the second torsion structure 10 is partially located in the relief groove 606. The relief groove 606 is used to accommodate the second torsion structure 10 and avoid interference between the second torsion structure 10 and the second fastener 6.

[0038] In some embodiments of this disclosure, see Figure 2 The first fixing member 5 is provided with at least one first mounting hole 501; and / or the second fixing member 6 is provided with at least one second mounting hole 607. The first mounting hole 501 is used to fix the first fixing member 5 to the screen part of the electronic device, and the second mounting hole 607 is used to fix the second fixing member 6 to the host part of the electronic device.

[0039] Figure 4 A schematic diagram illustrating the rotation process of the rotating shaft assembly provided in this embodiment of the disclosure; Figure 5 This is a cross-sectional schematic diagram illustrating the rotation process of the rotating shaft assembly provided in an embodiment of this disclosure. Please refer to... Figure 4-5The rotation process of the rotating shaft assembly is shown. When the rotating shaft assembly is closed, the plane where the first fixing member 5 is located is approximately parallel to the plane where the second fixing member 6 is located. When the first fixing member 5 rotates counterclockwise, the first gear 101 rotates counterclockwise and transmits power to the second gear 201. The clockwise rotating second gear 201 transmits power to the rack 602, thereby causing the first shaft 1 to translate to the right relative to the second fixing member 6. Finally, the axis of the first shaft 1 translates to the right by a distance a, which also causes the first fixing member 5 to translate to the right by a distance a.

[0040] Furthermore, embodiments of this disclosure also provide an electronic device, Figure 6 This is a schematic diagram of an electronic device provided according to an embodiment of this disclosure. (As shown...) Figure 6 As shown, the electronic device includes a first housing 100, a second housing 200, and a rotating shaft assembly of any of the above embodiments. The first housing 100 is fixedly connected to the first fixing member 5, and the second housing 200 is fixedly connected to the second fixing member 6.

[0041] In the electronic device provided in this embodiment, the first housing 100 is used to accommodate the screen portion, and the second housing 200 is used to accommodate the host portion. When the first fixing member 5 rotates away from the second fixing member 6, the first fixing member 5 is transmitted to the second fixing member 6 through the first gear 101, the second gear 201 and the rack 602, so that the first fixing member 5 is translated to the side facing the screen portion during the rotation, thereby reducing the distance between the screen portion and the user, saving the space occupied by the screen portion, and improving the user experience.

[0042] It should be noted that the electronic device provided in this disclosure embodiment may be, but is not limited to, a remote control, a tablet computer, an MP3 player (Moving Picture Experts Group Audio Layer III), an MP4 player (Moving Picture Experts Group Audio Layer IV), or a laptop computer.

The screen module 300 is disposed on the first housing 100, and the keyboard module 400 and the host module 500 are disposed on the second housing 200. When the laptop computer is opened, the first housing 100 can be rotated relative to the second housing 200, thereby causing the first fixing member 5 to rotate relative to the second fixing member 6. At this time, the first fixing member 5 can move the screen module 300 closer to the keyboard module 400, making the screen module 300 closer to the user.
