Description

Technical Field

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

[0002] With the rapid growth of the consumer electronics industry, users have increasingly higher demands for the portability and ergonomic features of electronic products, and laptops are beginning to develop in the direction of being thinner, lighter, and more user-friendly.

[0003] In pursuit of extreme thinness and aesthetics, laptops in related technologies often lack space on the bottom of the main unit for ventilation gaps, which increases the difficulty of heat dissipation. Utility Model Content

[0004] This application provides a hinge device and electronic device that can solve the problem that the lack of space on the bottom of a laptop host to arrange heat dissipation gaps increases the difficulty of heat dissipation.

[0005] The technical solution is as follows: On the one hand, a rotating shaft device is provided, the rotating shaft device comprising: a first fixing member, a second fixing member, and a reverse thrust member; The first fixing member and the thrust member are rotatably connected to the second fixing member, and the first fixing member and the thrust member are drive-connected. The rotating shaft device includes an open state and a closed state; When switching from the closed state to the open state, the first fixing member rotates relative to the second fixing member, and drives the push member to rotate relative to the second fixing member. At least a portion of the push member protrudes in a direction away from the first fixing member and the second fixing member, and generates a push force on the second fixing member.

[0006] The rotating shaft device of this application is suitable for connecting two movable modules of an electronic device. The two movable modules are respectively connected to a first fixed member and a second fixed member. The first fixed member and the thrust member are rotatably connected to the second fixed member, and the first fixed member and the thrust member are drively connected. When the rotating shaft device switches from a closed state to an open state, the first fixed member can drive the thrust member to rotate. The thrust member can protrude in a direction away from the first fixed member and the second fixed member. When the thrust member presses against the external support surface, the second fixed member can be lifted by the thrust member under the push of the reaction force. The second fixed member drives the movable module to lift up, and a heat dissipation gap can be formed between the bottom of the movable module and the external support surface. The rotating shaft device can not only realize the rotatable connection of the two movable modules, but also lift the movable module connected to the second fixed member in the open state, thereby improving the heat dissipation performance of the electronic device.

[0007] In some possible implementations, the thrust reverser includes a thrust reverser arm, the first end of which is rotatably connected to the second fixing member and kinetically connected to the first fixing member; the second end of the thrust reverser arm is capable of protruding in a direction away from the second fixing member.

[0008] With the above arrangement, the thrust reverser can utilize the thrust reverser arm to achieve a larger length, so that when the thrust reverser arm rotates around the first end, the second arm of the thrust reverser arm can protrude outward to a greater height, thereby raising the movable module connected to the second fixed member to a greater height.

[0009] In some possible implementations, the second end of the thrust arm is provided with a pushing part, which is used to press against the external support surface so that the thrust member generates a thrusting force on the second fixing member.

[0010] With the above arrangement, the pushing part can serve as the contact point between the thrust arm and the external support surface, providing a stable and reliable thrust force for the second fixing member.

[0011] In some possible implementations, the first fastener includes a first supporting plane, and the second fastener includes a second supporting plane; The rotating shaft device includes a closed state and an open state; In the closed state, the first support plane, the second support plane, and the thrust arm are parallel to each other; In the open state, the first support plane and the thrust arm are located on the upper and lower sides of the second support plane, respectively, and the first support plane and the thrust arm are arranged at an angle to the second support plane.

[0012] With the above arrangement, the first fastener can be connected to one of the movable modules of the electronic device using the first support surface, and the second fastener can be connected to another movable module of the electronic device using the second support surface, resulting in higher connection reliability.

[0013] Furthermore, in the closed state, the first support plane, the second support plane, and the thrust arm are parallel to each other, resulting in a smaller overall height for the entire rotating shaft device, which is beneficial for its widespread application in thin and light electronic devices. In the open state, the first support plane and the thrust arm are located on the upper and lower sides of the second support plane, respectively. The movable module connected to the first support plane is supported above the movable module connected to the second support plane, and the thrust arm can protrude to the bottom of the movable module connected to the second support plane, lifting the movable module upwards and creating a heat dissipation space at the bottom of the movable module.

[0014] In some possible implementations, when the first fixing member rotates relative to the second fixing member in a first direction, the first fixing member drives the thrust member to rotate relative to the second fixing member in a second direction, wherein the first direction and the second direction are the same or opposite.

[0015] With the above arrangement, the rotation direction of the thrust member relative to the second fixed member can be the same as or different from the rotation direction of the first fixed member relative to the second fixed member. The rotating shaft device has higher flexibility and can meet the usage requirements in different scenarios.

[0016] In some possible implementations, the rotating shaft device further includes a first rotating shaft component, a second rotating shaft component, and a gear assembly; The first rotating shaft is fixedly connected to the first fixed member, the second rotating shaft is fixedly connected to the thrust member, and the first rotating shaft and the second rotating shaft are respectively rotatably connected to the second fixed member; The gear assembly includes at least two meshing gear components, one of which is coaxially fixedly arranged on the first rotating shaft component, and the other gear component is coaxially fixedly arranged on the second rotating shaft component. The first rotating shaft component is connected to the second rotating shaft component through the at least two gear components.

[0017] With the above arrangement, the first fixed member is rotatably connected to the second fixed member via the first rotating shaft, and the thrust member is rotatably connected to the second fixed member via the second rotating shaft. Moreover, the gear assembly between the first rotating shaft and the second rotating shaft can realize the transmission connection between the first fixed member and the thrust member. The rotation of the first fixed member relative to the second fixed member can drive the thrust member to rotate relative to the second fixed member.

[0018] The first fixing component and the reverse thrust component are connected by a gear assembly, which has a simple structure, higher transmission reliability, and better compactness of the gear assembly. This helps to reduce the size of the rotating shaft device and promote its application in thin, light, and small electronic devices.

[0019] In some possible implementations, the gear component includes a first gear component and a second gear component; The first gear component is located on the first rotating shaft component, the second gear component is located on the second rotating shaft component, and the diameter of the first gear component is smaller than the diameter of the second gear component.

[0020] With the above arrangement, the first rotating shaft can drive the second gear with a larger diameter using the first gear with a smaller diameter, which can reduce the speed and increase the torque. Thus, the second gear can apply a large torque to the thrust reverser through the second rotating shaft. As a result, the thrust reverser can also generate a large thrust force on the second fixed member under the action of a smaller lever arm, without the need to use a thrust reverser with a large length, which is beneficial to reduce the size of the rotating shaft device.

[0021] In some possible implementations, the gear assembly further includes a third gear assembly and a fourth gear assembly, wherein the third gear assembly meshes with the first gear assembly, the fourth gear assembly meshes with the third gear assembly, and the second gear assembly meshes with the fourth gear assembly.

[0022] With the above arrangement, a third and fourth gear component are arranged between the first and second gear components, which enables the gear assembly to have multi-stage cooperative capability, achieve two-stage reduction, multi-stage distributed reduction ratio, uniform gear size, and a more compact overall structure, which is conducive to reducing the volume of the rotating shaft device.

[0023] In some possible implementations, the rotating shaft device further includes a torque mechanism located on at least one of the first rotating shaft and the second rotating shaft.

[0024] With the above arrangement, a torque mechanism is set on the first hinge and / or the second hinge. The torque mechanism can generate a stable resisting force to counteract the gravitational torque of the first fixing part. For example, the laptop screen can stop at any angle from 0° (closed) to 180° (fully open) or even 360° (2-in-1 laptop) without automatically falling due to gravity (for example, when opened to 45° or 90°, the screen can maintain its posture steadily without the need for hand support).

[0025] On the other hand, an electronic device is provided, which includes the rotating shaft device described in this application.

[0026] The electronic device in this embodiment uses the rotating shaft device of this application and has all the beneficial technical effects of all embodiments herein.

[0027] In some possible implementations, the electronic device is a laptop computer, and the electronic device further includes a first housing, a second housing, a screen module, and a host module. The screen module is disposed in the first housing, the host module is disposed in the second housing, and the screen module and the host module are communicatively connected. The first housing is connected to the first fixing member, and the second housing is connected to the second fixing member.

[0028] With the above arrangement, the laptop computer can utilize the hinge device provided in this application to improve heat dissipation performance.

[0029] In some possible implementations, when the first housing rotates open relative to the second housing, the first housing causes the first fixing member to rotate relative to the second fixing member, the first fixing member causes the thrust member to rotate relative to the second fixing member, at least a portion of the thrust member protrudes toward the bottom of the second housing and generates an upward thrusting force on the second fixing member, and the second fixing member causes the second housing to lift upward.

[0030] With the above arrangement, after the first shell of the laptop drives the screen module to flip open, the push-back component and the second fixing component can lift the second shell and the host module upward. A heat dissipation space is formed between the edge of the second shell near the first shell and the external support surface, thereby improving the heat dissipation effect of the laptop.

[0037] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0039] On the one hand, combined with Figure 1 and Figure 2 As shown, this application embodiment provides a rotating shaft device 100, which includes: a first fixing member 1, a second fixing member 2, and a thrust member 3.

[0040] The first fixing member 1 and the thrust member 3 are rotatably connected to the second fixing member 2, and the first fixing member 1 and the thrust member 3 are connected by transmission.

[0041] The rotating shaft device 100 includes an open state and a closed state.

[0042] When switching from the closed state to the open state, the first fixing member 1 rotates relative to the second fixing member 2, and drives the push member 3 to rotate relative to the second fixing member 2. At least a portion of the push member 3 protrudes in a direction away from the first fixing member 1 and the second fixing member 2, and generates a push force on the second fixing member 2.

[0043] The rotating shaft device 100 of this application is suitable for connecting two movable modules of an electronic device. The two movable modules are respectively connected to a first fixing member 1 and a second fixing member 2. The first fixing member 1 and the push-back member 3 are rotatably connected to the second fixing member 2, and the first fixing member 1 and the push-back member 3 are drive-connected. When the rotating shaft device 100 switches from a closed state to an open state, the first fixing member 1 can drive the push-back member 3 to rotate. The push-back member 3 can protrude in a direction away from the first fixing member 1 and the second fixing member 2. When the push-back member 3 presses against the external support surface 001, the second fixing member 2 can be lifted by the push-back member 3 under the push of the reaction force. The second fixing member 2 drives the movable module to lift up. A heat dissipation gap can be formed between the bottom of the movable module and the external support surface 001. The rotating shaft device 100 can not only realize the rotatable connection of the two movable modules, but also lift the movable module connected to the second fixing member 2 in the open state, thereby improving the heat dissipation performance of the electronic device.

[0044] Combination Figure 3 and Figure 4 As shown, in some possible implementations, the thrust reverser 3 includes a thrust reverser arm 31, the first end 31a of which is rotatably connected to the second fixing member 2 and is drive-connected to the first fixing member 1; the second end 31b of the thrust reverser arm 31 can protrude in a direction away from the second fixing member 2.

[0045] With the above arrangement, the thrust reverser 3 can utilize the thrust reverser arm 31 to arrange a larger length, so that when the thrust reverser arm 31 rotates around the first end 31a, the second arm of the thrust reverser arm 31 can protrude outward to a greater height, thereby raising the movable module connected to the second fixing member 2 to a greater height.

[0046] In some possible implementations, the width of the second end 31b of the thrust reverser 31 is smaller than the width of the first end 31a of the thrust reverser 31. This not only allows the first end 31a of the thrust reverser 31 to have sufficient size to be rotatably connected to the first fixing member 1, but also reduces the weight of the second end 31b of the thrust reverser 31, thereby reducing the moment of inertia of the thrust reverser 31.

[0047] Combination Figure 3 and Figure 4 As shown, in some possible implementations, the second end 31b of the thrust arm 31 is provided with a pushing part 311, which is used to press against the external support surface 001 so that the thrust member 3 generates a thrusting force on the second fixing member 2.

[0048] With the above arrangement, the pushing part 311 can serve as the contact point between the thrust arm 31 and the external support surface 001, providing a stable and reliable thrust force for the second fixing member 2.

[0049] In some possible implementations, the pushing part 311 includes a roller structure, which is rotatably arranged at the second end 31b of the thrust arm 31. When the pushing part 311 presses against the outer support surface 001, the roller structure can roll on the outer support surface 001, thereby helping to reduce the friction between the pushing part 311 and the outer support surface. The thrust arm 31 rotates more smoothly relative to the outer support surface, which helps to reduce the difficulty of the thrust arm 31 rotating out or rotating back.

[0050] Combination Figure 3 and Figure 4 As shown, in some possible implementations, the first fastener 1 includes a first support plane 11a, and the second fastener 2 includes a second support plane 20a.

[0051] The rotating shaft device 100 includes a closed state and an open state.

[0052] In the closed state, the first support plane 11a, the second support plane 20a, and the thrust arm 31 are parallel to each other.

[0053] In the open state, the first support plane 11a and the thrust arm 31 are located on the upper and lower sides of the second support plane 20a, respectively, and the first support plane 11a and the thrust arm 31 are arranged at an angle to the second support plane 20a.

[0054] With the above arrangement, the first fastener 1 can be connected to one of the movable modules of the electronic device using the first support surface, and the second fastener 2 can be connected to another movable module of the electronic device using the second support surface, resulting in higher connection reliability.

[0055] Furthermore, in the closed state, the first support plane, the second support plane 20a, and the thrust arm 31 are parallel to each other, resulting in a smaller overall height for the rotating shaft device 100, which is beneficial for its widespread application in thin and light electronic devices. In the open state, the first support plane 11a and the thrust arm 31 are located on the upper and lower sides of the second support plane 20a, respectively. The movable module corresponding to the first support plane 11a is supported above the movable module corresponding to the second support plane 20a, and the thrust arm 31 can protrude to the bottom of the movable module corresponding to the second support plane 20a, lifting the movable module upwards and creating a heat dissipation space at the bottom of the movable module.

[0056] Among some possible implementations, refer to Figure 3 , Figure 4 and Figure 5 As shown, the first fixing member 1 includes a support plate 11, at least a portion of which is plate-shaped, and the surface of the support plate 11 facing the second fixing member 2 forms a first supporting plane 11a.

[0057] In some possible implementations, when the first fixing member 1 rotates relative to the second fixing member 2 in a first direction, the first fixing member 1 drives the reverse thrust member 3 to rotate relative to the second fixing member 2 in a second direction, where the first direction and the second direction are the same or opposite.

[0058] With the above arrangement, the rotation direction of the thrust member 3 relative to the second fixing member 2 can be the same as or different from the rotation direction of the first fixing member 1 relative to the second fixing member 2. The rotating shaft device 100 has higher flexibility and can meet the usage requirements in different scenarios.

[0059] Combination Figure 3 , Figure 4 and Figure 5 As shown, in some possible implementations, the rotating shaft device 100 further includes a first rotating shaft 4, a second rotating shaft 5, and a gear assembly 6.

[0060] The first rotating shaft 4 is fixedly connected to the first fixed member 1, the second rotating shaft 5 is fixedly connected to the reverse thrust member 3, and the first rotating shaft 4 and the second rotating shaft 5 are respectively rotatably connected to the second fixed member 2.

[0061] The gear assembly 6 includes at least two meshing gear components 61, one of which is coaxially fixed on the first rotating shaft 4, and the other gear component 61 is coaxially fixed on the second rotating shaft 5. The first rotating shaft 4 is connected to the second rotating shaft 5 through the at least two gear components 61.

[0062] With the above arrangement, the first fixing member 1 is rotatably connected to the second fixing member 2 via the first rotating shaft 4, and the thrust member 3 is rotatably connected to the second fixing member 2 via the second rotating shaft 5. Moreover, the gear assembly 6 between the first rotating shaft 4 and the second rotating shaft 5 can realize the transmission connection between the first fixing member 1 and the thrust member 3. The rotation of the first fixing member 1 relative to the second fixing member 2 can drive the thrust member 3 to rotate relative to the second fixing member 2.

[0063] The first fixing member 1 and the reverse thrust member 3 are connected by a gear assembly 6, which has a simple structure, higher transmission reliability, and better compactness of the gear assembly 6. This helps to reduce the size of the rotating shaft device 100 and promote the application of the rotating shaft device 100 in thin, light and small electronic devices.

[0064] Among some possible implementations, refer to Figure 5 As shown, the axes of the first rotating shaft 4 and the second rotating shaft 5 are arranged parallel to each other on the second fixing member 2. Exemplarily, the first fixing member 1 and the thrust member 3 are located on opposite sides of the axial direction of the second fixing member 2.

[0065] Among some possible implementations, refer to Figure 3 , Figure 4 and Figure 5 As shown, the first fixing member 1 includes a support plate 11 and a bending plate 12. The bending plate 12 is located at the edge of the support and is bent toward the side where the second fixing member 2 is located. The first rotating shaft 4 is fixedly arranged on the bending plate 12.

[0066] Among some possible implementations, refer to Figure 3 , Figure 4 and Figure 5 As shown, the second fixing member 2 includes a first side plate 21 and a second side plate 22. The first side plate 21 and the second side plate 22 are arranged in parallel and spaced apart, and are respectively rotatably connected to the first rotating shaft member 4 and the second rotating shaft member 5. The gear assembly 6 is located between the first side plate 21 and the second side plate 22.

[0067] Combined with the diagram Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the top of the first side plate 21 and the second side plate 22 are respectively provided with a bent portion 23. The bent portions 23 on the first side plate 21 and the second side plate 22 are kept parallel and can form a second support plane 20a.

[0068] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some possible implementations, gear 61 includes a first gear 61a and a second gear 61b.

[0069] The first gear component 61a is located on the first rotating shaft component 4, and the second gear component 61b is located on the second rotating shaft component 5, and the diameter of the first gear component 61a is smaller than the diameter of the second gear component 61b.

[0070] With the above arrangement, the first rotating shaft 4 can drive the second gear 61b with a larger diameter using the first gear 61a with a smaller diameter, which can reduce the rotational speed and increase the torque. Thus, the second gear 61b can apply a large torque to the thrust reverser 3 through the second rotating shaft 5. As a result, the thrust reverser 3 can also generate a large thrust force on the second fixed member 2 under the action of a smaller lever arm, without the need to use a thrust reverser 3 with a larger length, which is beneficial to reducing the size of the rotating shaft device 100.

[0071] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some possible implementations, gear 61 further includes a third gear 61c and a fourth gear 61d, the third gear 61c being meshed with the first gear 61a, the fourth gear 61d being meshed with the third gear 61c, and the second gear 61b being meshed with the fourth gear 61d.

[0072] With the above arrangement, a third gear 61c and a fourth gear 61d are arranged between the first gear 61a and the second gear 61b, so that the gear assembly 6 has a multi-stage cooperative capability, can achieve two-stage reduction, multi-stage distributed reduction ratio, uniform gear size, and a more compact overall structure, which is conducive to reducing the volume of the rotating shaft device 100.

[0073] Combination Figure 2 and Figure 5 As shown, in some possible implementations, the rotating shaft device 100 further includes a torque mechanism 7, which is located on at least one of the first rotating shaft member 4 and the second rotating shaft member 5.

[0074] With the above arrangement, a torque mechanism 7 is provided on the first pivot 4 and / or the second pivot 5. The torque mechanism 7 can generate a stable resisting force to counteract the gravitational torque of the first fixing member 1. For example, it can stop the laptop screen at any angle from 0° (closed) to 180° (fully open) or even 360° (2-in-1 laptop) without automatically falling due to gravity (for example, when opened to 45° or 90°, the screen can maintain its posture steadily without the need for hand support).

[0075] On the other hand, combining Figure 6 , Figure 7 and Figure 8 As shown in the figure, an embodiment of this application provides an electronic device, which includes the rotating shaft device 100 of this application.

[0076] The electronic device in this embodiment uses the rotating shaft device 100 of this application and has all the beneficial technical effects of all embodiments herein.

[0077] Combination Figure 6 , Figure 7 and Figure 8 As shown, in some possible implementations, the electronic device is a laptop computer, which also includes a first housing 200, a second housing 300, a screen module 400, and a host module 500. The screen module 400 is disposed in the first housing 200, and the host module 500 is disposed in the second housing 300. The screen module 400 and the host module 500 are communicatively connected.

[0078] The first housing 200 is connected to the first fixing member 1, and the second housing 300 is connected to the second fixing member 2.

[0079] With the above arrangement, the laptop computer can use the hinge device 100 provided in this application to improve heat dissipation performance.

[0080] In some possible implementations, the first support surface is parallel to the extending direction of the first housing 200, and the second support surface is parallel to the extending direction of the second housing 300. For example, the first support surface may be attached to the outer surface of the first housing 200 or embedded inside the first housing 200. The second support surface may be attached to the outer surface of the second housing 300 or embedded inside the second housing 300.

[0081] Combination Figure 6 , Figure 7 and Figure 8 As shown, in some possible implementations, when the first housing 200 is rotated open relative to the second housing 300, the first housing 200 drives the first fixing member 1 to rotate relative to the second fixing member 2. The first fixing member 1 drives the push member 3 to rotate relative to the second fixing member 2. At least a portion of the push member 3 protrudes towards the bottom of the second housing 300 and generates an upward push force on the second fixing member 2. The second fixing member 2 drives the second housing 300 to lift upward.

[0082] With the above arrangement, after the first shell of the laptop drives the screen module to flip open, the push-back component and the second fixing component can lift the second shell and the host module upward.
