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 laptops have a fixed hinge, so when the screen is flipped open, the relative distance between the screen and the main unit is fixed. In order to achieve thinness and aesthetics, laptops are designed with a relatively small distance between the screen and the main unit, which affects the heat dissipation of the main unit. Utility Model Content

[0004] In view of this, the present disclosure provides a hinge assembly and an electronic device that can improve the heat dissipation effect of the electronic device.

[0005] Specifically, the following technical solutions are included: In a first aspect, the present disclosure provides a rotating shaft assembly, including a first shaft, a first fixing member, a second fixing member, a first gear, and a second gear, wherein one end of the first shaft is fixedly connected to the first fixing member; The first gear is fixedly sleeved on the first shaft, and the second gear is fixedly connected to the side of the second fixing member near the first fixing member, and the first gear meshes with the second gear.

[0006] In some embodiments of this disclosure, the second fixing member includes a fixing plate and a connecting portion, the connecting portion being connected to one side of the fixing plate, and a portion of the tooth surface of the second gear being fixedly connected to the connecting portion. The connecting portion covers a portion of the tooth surface of the second gear, thereby limiting the angle at which the second gear can mesh with the first gear, and thus limiting the angle at which the first fixing member can rotate relative to the second fixing member.

[0007] In some embodiments of this disclosure, the first fastener is provided with at least one first mounting hole; and / or The mounting plate is provided with at least one second mounting hole. The first mounting hole is used to fix the first fixing member to the screen part of the electronic device, and the second mounting hole is used to fix the second fixing member to the main body part of the electronic device.

[0008] In some embodiments of this disclosure, the rotating shaft assembly further includes a second shaft and a first connecting piece. The second shaft passes through the second gear and is coaxially arranged with the second gear. One end of the first connecting piece is sleeved on the first shaft, and the other end of the first connecting piece is sleeved on the second shaft. The first connecting piece and the second shaft are used to fix the relative positions of the first shaft and the second shaft, thereby keeping the first gear meshing with the second gear.

[0009] In some embodiments of this disclosure, the rotating shaft assembly further includes a second connecting piece, one end of which is sleeved on the first shaft body, and the other end of which is sleeved on the second shaft body. The first gear and the second gear are located between the first connecting piece and the second connecting piece. The second connecting piece and the first connecting piece cooperate to connect the first shaft body and the second shaft body, ensuring stable meshing between the first gear and the second gear.

[0010] In some embodiments of this disclosure, the shaft assembly further includes a torque structure connected to the end of the first shaft away from the first fixing member. The torque structure provides resistance to the rotation of the first shaft, allowing the first shaft to remain relatively stationary with respect to the second shaft when no force is applied.

[0011] In some embodiments of this disclosure, a stepped surface is provided at the connection between the first fixing member and the first shaft body, and the first connecting piece and the second connecting piece are clamped between the stepped surface and the torsion structure. The clamping structure formed by the stepped surface and the torsion structure helps to improve the assembly stability of the shaft assembly.

[0012] In some embodiments of this disclosure, a portion of the edge of one end of the first connecting piece coincides with the edge of the first gear in the axial direction of the first gear, and a portion of the edge of the other end of the first connecting piece coincides with the edge of the second gear in the axial direction of the second gear; and / or A portion of the edge at one end of the second connecting piece coincides with the edge of the first gear along its axial direction, and a portion of the edge at the other end of the second connecting piece coincides with the edge of the second gear along its axial direction. The structure of the first connecting piece and / or the second connecting piece prevents contact between the first connecting piece and / or the second connecting piece and the first or second fixing member, thereby preventing the first connecting piece and / or the second connecting piece from affecting the rotatable angle of the third fixing member relative to the fourth fixing member.

[0013] In some embodiments of this disclosure, the radius of the first gear is smaller than the radius of the second gear. A larger second gear can increase the distance the first fixing member can move in the vertical direction, thereby increasing the distance between the first and second fixing members.

[0014] Secondly, embodiments of this disclosure provide an electronic device, the electronic device including a first housing, a second housing and a rotating shaft assembly as described in any of the first aspects above, wherein the first housing is fixedly connected to the first fixing member, and the second housing is fixedly connected to the second fixing member.

[0015] In some embodiments of this disclosure, the electronic device is a laptop computer, which further includes a screen module, a keyboard module, and a host module. The screen module is disposed in the first housing, and the keyboard module and the host module are disposed in the second housing.

[0016] The beneficial effects of the technical solutions provided in this disclosure include at least the following: In the rotating shaft assembly provided in this embodiment, the first fixing member and the second fixing member are respectively used to connect the screen part and the host part of the electronic device. When the first fixing member rotates away from the second fixing member, the first fixing member is connected to the first gear. The first gear rolls along the circumference of the second gear, causing the first fixing member to move away from the second fixing member during rotation. This increases the distance between the screen part and the host part, preventing the screen part from being too close to the host part and affecting the heat dissipation of the host part, thus improving the heat dissipation effect of the electronic device.

[0020] The accompanying drawings have illustrated specific embodiments of this disclosure, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0021] 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.

[0022] 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 first fixing member 3, a second fixing member 4, a first gear 5, and a second gear 6. One end of the first shaft 1 is fixedly connected to the first fixing member 3. The first gear 5 is fixedly sleeved on the first shaft 1, and the second gear 6 is fixedly connected to the side of the second fixing member 4 near the first fixing member 3. The first gear 5 and the second gear 6 mesh.

[0023] In the rotating shaft assembly provided in this embodiment, the first fixing member 3 and the second fixing member 4 are respectively used to connect the screen part and the host part of the electronic device. When the first fixing member 3 rotates away from the second fixing member 4, since the first fixing member 3 is connected to the first gear 5, the first gear 5 rolls along the circumference of the second gear 6, causing the first fixing member 3 to move away from the second fixing member 4 during rotation. This increases the distance between the screen part and the host part, preventing the screen part from being too close to the host part and affecting the heat dissipation of the host part, which is beneficial to improving the heat dissipation effect of the electronic device.

[0024] 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.

[0025] See Figure 1The rotating shaft assembly provided in this embodiment includes a first shaft 1, a first fixing member 3, a second fixing member 4, a first gear 5, and a second gear 6. One end of the first shaft 1 is fixedly connected to the first fixing member 3. The first gear 5 is fixedly sleeved on the first shaft 1. The second gear 6 is fixedly connected to the side of the second fixing member 4 near the first fixing member 3, and the first gear 5 and the second gear 6 mesh. When the first fixing member 3 rotates relative to the second fixing member 4, the first shaft 1 drives the first gear 5 to rotate circumferentially along the second gear 6, causing the first shaft 1 to move away from the second fixing member 4, thus increasing the distance between the first fixing member 3 and the second fixing member 4. Since the first fixing member 3 is used to connect to the screen of the electronic device, and the second fixing member 4 is used to connect to the main unit of the electronic device, this rotating shaft assembly can increase the distance between the screen and the main unit, preventing the screen from being too close to the main unit and affecting the heat dissipation of the main unit, thereby improving the heat dissipation effect of the electronic device.

[0026] In some embodiments of this disclosure, such as Figure 1 As shown, the second fixing member 4 includes a fixing plate 401 and a connecting part 402. The connecting part 402 is connected to one side of the fixing plate 401, and a portion of the tooth surface of the second gear 6 is fixedly connected to the connecting part 402. The location of the connecting part 402 on one side of the fixing plate 401 facilitates the connection of the fixing plate 401 to the housing of the electronic device, avoiding the connecting part 402 occupying excessive volume within the housing. Furthermore, the connecting part 402 covers a portion of the tooth surface of the second gear 6, thereby limiting the meshing angle between the second gear 6 and the first gear 5, and thus limiting the rotational angle of the first fixing member 3 relative to the second fixing member 4.

[0027] It should be noted that a lubricant may be applied between the first gear 5 and the second gear 6 to reduce the resistance when rotating the first shaft 1 and to improve the service life of the shaft assembly.

[0028] Optionally, see Figure 2 The first fixing member 3 is provided with at least one first mounting hole 301; and / or the fixing plate 401 is provided with at least one second mounting hole 403. The first mounting hole 301 is used to fix the first fixing member 3 to the screen part of the electronic device, and the second mounting hole 403 is used to fix the second fixing member 4 to the host part of the electronic device.

[0029] For example, the first fastener 3 is provided with three first mounting holes 301, and the fixing plate 401 is provided with four second mounting holes 403.

[0030] In some embodiments of this disclosure, such as Figure 1As shown, the rotating shaft assembly also includes a second shaft 2 and a first connecting piece 7. The second shaft 2 passes through the second gear 6 and is coaxially arranged with the second gear 6. One end of the first connecting piece 7 is sleeved on the first shaft 1, and the other end of the first connecting piece 7 is sleeved on the second shaft 2. The first connecting piece 7 and the second shaft 2 are used to fix the relative positions of the first shaft 1 and the second shaft 2, thereby keeping the first gear 5 meshing with the second gear 6.

[0031] Optionally, see Figure 1-2 The rotating shaft assembly also includes a second connecting piece 8. One end of the second connecting piece 8 is sleeved on the first shaft 1, and the other end is sleeved on the second shaft 2. The first gear 5 and the second gear 6 are located between the first connecting piece 7 and the second connecting piece 8. The second connecting piece 8 and the first connecting piece 7 cooperate to connect the first shaft 1 and the second shaft 2, and are located on opposite sides of the first gear 5 and the second gear 6, respectively, thereby ensuring stable meshing between the first gear 5 and the second gear 6.

[0032] In some embodiments of this disclosure, such as Figure 1 As shown, the rotating shaft assembly also includes a torque structure 9, which is connected to the end of the first shaft 1 away from the first fixing member 3. The torque structure 9 is used to provide resistance to the rotation of the first shaft 1, so that the first shaft 1 can remain relatively stationary with respect to the second shaft 2 when no force is applied.

[0033] In some embodiments of this disclosure, see Figure 1 A stepped surface 101 is provided at the connection between the first fixing member 3 and the first shaft 1. The first connecting piece 7 and the second connecting piece 8 are clamped between the stepped surface 101 and the torsion structure 9. The clamping structure formed by the stepped surface 101 and the torsion structure 9 helps to improve the assembly stability of the rotating shaft assembly.

[0034] In some embodiments of this disclosure, such as Figure 1-2 As shown, a portion of the edge of one end of the first connecting piece 7 coincides with the edge of the first gear 5 in the axial direction, and a portion of the edge of the other end of the first connecting piece 7 coincides with the edge of the second gear 6 in the axial direction; and / or, a portion of the edge of one end of the second connecting piece 8 coincides with the edge of the first gear 5 in the axial direction, and a portion of the edge of the other end of the second connecting piece 8 coincides with the edge of the second gear 6 in the axial direction. The fact that both ends of the first connecting piece 7 and / or the second connecting piece 8 coincide with the edges of the first gear 5 and the second gear 6 respectively prevents contact between the first connecting piece 7 and / or the second connecting piece 8 and the first fixing member 3 or the second fixing member 4, thereby preventing the first connecting piece 7 and / or the second connecting piece 8 from affecting the rotatable angle of the third fixing member 3 relative to the fourth fixing member 4.

[0035] Figure 3This is a schematic diagram illustrating the hinge assembly provided in an embodiment of this disclosure in an unfolded state and a folded state. See also some embodiments of this disclosure. Figure 3 The radius of the first gear 5 is smaller than the radius of the second gear 6. The larger second gear 6 can increase the distance that the first fixing member 3 can move in the vertical direction, thereby increasing the distance between the first fixing member 3 and the second fixing member 4. This is beneficial for further increasing the distance between the screen part and the host part, thereby improving the heat dissipation effect of the electronic device.

[0036] like Figure 3 As shown, in the folded state, the plane where the first fixing member 3 is located is roughly parallel to the screen where the second fixing member 4 is located, and the first shaft 1 is located diagonally above the second shaft 2. In the unfolded state, the first shaft 1 rotates to be directly above the second shaft 2, thereby increasing the distance between the first fixing member 3 and the second fixing member 4.

[0037] Furthermore, embodiments of this disclosure also provide an electronic device, Figure 4 This is a schematic diagram illustrating the unfolded and folded states of the electronic device provided in the embodiments of this disclosure. Figure 4 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 3, and the second housing 200 is fixedly connected to the second fixing member 4.

[0038] 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 3 rotates away from the second fixing member 4, since the first fixing member 3 is connected to the first gear 5, the first gear 5 rolls along the circumference of the second gear 6, causing the first fixing member 3 to move away from the second fixing member 4 during rotation. This increases the distance between the screen portion and the host portion, preventing the screen portion from being too close to the host portion and affecting the heat dissipation of the host portion, thus improving the heat dissipation effect of the electronic device.

[0039] 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 laptop computer also includes a screen module 300, a keyboard module 400, and a host module 500. 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 drive the screen module 300 to move away from the keyboard module 400, so that the screen module 300 is further away from the host module 500, thereby avoiding the screen module 300 being too close to the host module 500 and affecting heat dissipation.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
