Description

Technical Field

[0001] This invention relates to the field of rotating shaft equipment technology, and more specifically to a rotating shaft mechanism and electronic equipment. Background Technology

[0002] Typically, flip-top electronic devices such as laptops and mobile phones have a hinge mechanism between the monitor and keyboard to provide the torque needed to open the monitor relative to the keyboard. However, for purely manual hinge mechanisms, considering that providing the appropriate torque to allow the top cover to remain at any angle requires additional parts such as friction plates and cams, resulting in excessive parts and inconvenient manufacturing and assembly, and potentially requiring users to exert considerable effort to open or close the device due to excessive torque, electrically driven hinge mechanisms have been developed. However, these fully electrically driven hinge mechanisms suffer from several drawbacks: the maximum rotation angle is entirely limited by the electric drive mechanism, failing to meet users' requirements for fine-tuning according to their usage habits, and the electronic device becomes completely unusable in the event of a malfunction in the electric drive mechanism. Summary of the Invention

[0003] Therefore, in order to overcome the above problems, the present invention provides a rotating shaft mechanism that can realize dual control of electronic drive and manual operation, as well as an electronic device corresponding to the rotating shaft mechanism.

[0004] In a first aspect, the present invention provides a rotating shaft mechanism, comprising:

[0005] The component consists of a fixed part and a rotating part. The rotating part is sleeved on the outside of a bearing, and the bearing passes through the fixed part and can rotate relative to the fixed part.

[0006] The first torque assembly and the second torque assembly are both sleeved on the outside of the bearing, and the second torque assembly is connected to the rotating component; the first torque assembly is used to generate a first torque when the bearing rotates, and the second torque assembly is used to generate a second torque when the rotating component rotates relative to the bearing.

[0007] A rotary drive has a first meshing member at its output end and a corresponding second meshing member fixed to the outside of the bearing. The rotary drive can drive the bearing to rotate via the first and second meshing members.

[0008] The rotating component has a first state in which it rotates synchronously with the bearing when the rotating drive is working, and a second state in which it rotates relative to the bearing under the drive of an external force greater than the second torque when the rotating drive is not working.

[0009] Furthermore, the second torque assembly includes a locking member and an elastic member. The locking member is fixedly connected to the bearing, and the elastic member is sleeved outside the bearing. One end of the elastic member abuts against the locking member, and the other end abuts against the rotating member.

[0010] Furthermore, the rotating shaft mechanism also includes:

[0011] The driven member is sleeved outside the bearing, and the driven member and the rotating member are fixedly arranged relative to each other along the circumference of the bearing so that the driven member and the rotating member rotate synchronously.

[0012] Furthermore, the rotating component and the driven component are respectively provided with corresponding first fixing grooves and first fixing blocks, and the driven component and the rotating component are fixedly arranged relative to each other along the circumference of the bearing through the first fixing grooves and the first fixing blocks.

[0013] Furthermore, the rotating shaft mechanism also includes:

[0014] The first fixed shim is sleeved on the outside of the bearing and is fixedly disposed relative to the bearing in both the circumferential and axial directions; the first fixed shim is disposed between the driven member and the rotating member.

[0015] Furthermore, the rotating shaft mechanism also includes:

[0016] The second fixing washer is sleeved on the outside of the bearing and is fixed relative to the bearing in both the circumferential and axial directions; the second fixing washer is located on the side of the driven member away from the rotating member, and the elastic member abuts against the second fixing washer.

[0017] Furthermore, the rotating shaft mechanism also includes:

[0018] The third fixing washer is sleeved on the outside of the bearing and is fixed relative to the bearing in both the circumferential and axial directions; the rotating component abuts against the first fixing washer on the other side relative to the second torque assembly.

[0019] Furthermore, the second torque component is the first torque envelope, and the rotating component is fixed on the outer circumference of the first torque envelope.

[0020] Furthermore, the rotating shaft mechanism also includes:

[0021] The first angle sensor is set up corresponding to the bearing to detect the first rotation angle of the bearing;

[0022] The second angle sensor is configured corresponding to the bearing and the second torque component to detect the second rotation angle of the second torque component relative to the bearing.

[0023] In a first aspect, the present invention provides an electronic device, comprising:

[0024] The first body, the second body, and the rotating shaft mechanism described in any embodiment of the first aspect, wherein the first body is connected to the fixed component in the rotating shaft mechanism, and the second body is connected to the rotating component in the rotating shaft mechanism.

[0025] Furthermore, an electronic lock is installed between the first and second units. The electronic lock includes:

[0026] The lock body is located inside the first mechanism and has a locking control mechanism and a bolt. The bolt can slide under the control of the locking control mechanism to extend out of the lock body or retract into the lock body.

[0027] A locking tongue groove corresponding to the locking tongue is provided on the second body;

[0028] When the rotation angle of the rotating part relative to the fixed part is 0 degrees, the locking control mechanism controls the locking tongue to slide out into the locking tongue groove to lock the first body and the second body.

[0029] The technical solution of this invention has the following advantages:

[0030] The rotating shaft mechanism provided by this invention, by setting a first torque component that generates a first torque when the bearing rotates, and a second torque component connected to the rotating member that generates a second torque when the rotating member rotates relative to the bearing, ensures that when the rotating drive is working and drives the bearing to rotate via the first and second engaging components, the rotating member will rotate synchronously with the bearing under the drive of the second torque component (there is no other force at the rotating member that can overcome the second torque, so its rotation is limited by the second torque component connected to it). This also ensures that the top cover of the electronic device corresponding to this rotating shaft mechanism can be opened by the rotating drive, and that this rotation must overcome the first torque. The force allows the corresponding electronic device to open more smoothly, and the top cover can be suspended at the controlled opening angle. At the same time, when the rotary drive is not working, if an external force greater than the second torque is applied to the rotary component, the rotary component can disengage from the synchronous state driven by the second torque component and generate rotation relative to the bearing. This means that the opening angle of the electronic device corresponding to the rotating shaft mechanism is not completely limited by the drive of the rotary drive. Users can fine-tune the opening of the top cover of the corresponding electronic device according to their own needs after the rotary drive drives the top cover of the electronic device to open to a certain angle. Users can also manually open the top cover of the electronic device in case of failure of the rotary drive. Attached Figure Description

[0069] Furthermore, to provide a concise description of exemplary embodiments, not all features of actual embodiments (i.e., those features not related to the currently considered best mode for carrying out the invention, or those features not related to implementing the invention) may be described. Moreover, the technical features involved in the different embodiments of the invention described below may be combined with each other as long as they do not conflict with each other.

[0070] Example 1

[0071] Please refer to Figure 1 The present invention provides an electronic device, which includes a first body 1, a second body 2 and a rotating shaft mechanism 3, wherein both the first body 1 and the second body 2 are connected to the rotating shaft mechanism 3, and the second body 2 can rotate relative to the first body 1 through the rotating shaft mechanism 3.

[0072] Please refer to Figure 2 and Figure 3The rotating shaft mechanism 3 includes a fixed component 301, a rotating component 302, a bearing 303, a first torque component 304, a second torque component 305, a rotating drive component 306, a first meshing component 307, and a second meshing component 308. The rotating component 302 is sleeved on the outside of the bearing 303; the bearing 303 passes through the fixed component 301 and can rotate relative to the fixed component 301; the first torque component 304 and the second torque component 305 are both sleeved on the outside of the bearing 303, and the second torque component 305 is connected to the rotating component 302; the first torque component 304 is used to generate a first torque when the bearing 303 rotates, and the second torque component 305 is used to generate a second torque when the rotating component 302 rotates relative to the bearing 303; the output end of the rotary drive component 306 is provided with a first engagement component 307, and a corresponding second engagement component 308 is fixed on the outside of the bearing 303; the rotary drive component 306 can drive the bearing 303 to rotate via the first engagement component 307 and the second engagement component 308; the rotating component 302 has a first state in which it rotates synchronously with the bearing 303 when the rotary drive component 306 is working, and a second state in which it rotates relative to the bearing 303 under the drive of an external force greater than the second torque when the rotary drive component 306 is not working.

[0073] Specifically, the second body 2 in the electronic device is fixedly connected to the rotating component 302, and the first body 1 is fixedly connected to the fixing component 301.

[0074] Specifically, the rotary drive 306 can be Figure 3 The motor shown in the figure, the first engaging member 307 and the second engaging member 308 can be Figure 3 The diagram shows two meshing bevel gears. The first meshing element 307 and the second meshing element can also be two meshing spur gears. The first meshing element 307 and the second meshing element 308 can also be a spur gear and a worm gear, respectively.

[0075] Furthermore, although not shown in the figure, those skilled in the art should understand that, in order to control the operation of the rotary drive 306, the electronic device also includes a drive controller.

[0076] Please refer to Figure 3 To accurately obtain the opening angle of the first body 1, the rotating shaft mechanism 3 may further include a first angle sensor 313 and a second angle sensor 314. The first angle sensor 313 is correspondingly arranged with the bearing 303 to detect the first rotation angle of the bearing 303. The second angle sensor 314 is correspondingly arranged with the bearing 303 and the second torque component 305 to detect the second rotation angle of the second torque component 305 relative to the bearing 303. Both the first angle sensor 313 and the second angle sensor 314 are connected to the drive controller so that the drive controller can obtain the opening angle of the first body 1.

[0077] At this point, please refer to Figure 4 An electronic lock can also be installed between the first body 1 and the second body 2. The electronic lock includes a lock body 41 installed in the first body 1 and a latch groove installed on the second body 2. The lock body 41 has a locking control mechanism 42 and a latch 43. The latch 43 can slide out of the lock body 41 or retract into the lock body 41 under the control of the locking control mechanism 42. When the rotation angle of the rotating member 302 relative to the fixed member 301 is 0 degrees, the locking control mechanism 42 controls the latch 43 to slide out into the latch groove to lock the first body 1 and the second body 2.

[0078] Specifically, when both the first and second rotation angles acquired by the drive controller are 0 degrees, the drive controller can directly command the locking control mechanism 42 to lock; when the second rotation angle acquired by the drive controller is 0 degrees, but the first rotation angle is greater than 0 degrees, the drive controller controls the rotary drive component 306 to run until the first rotation angle is also 0 degrees, and then commands the locking control mechanism 42 to lock; when the first rotation angle acquired by the drive controller is 0 degrees, but the second rotation angle is greater than 0 degrees, the drive controller controls the rotary drive component 306 to continue running in the closing direction, causing the bearing 303 to drive the rotary drive component 306 to rotate. The rotating component 302 continues to rotate towards the closing direction at the angle corresponding to the second rotation angle (at this time, although the values ​​of the first rotation angle and the second rotation angle are not 0, the rotation angle of the rotating component 302 relative to the fixed component 301 has returned to 0 degrees), and then instructs the locking control mechanism 42 to lock. Based on this situation, the initial positions of the first angle sensor 313 and the second angle sensor 314 will change when the first body 1 is opened next time. Therefore, the drive controller initializes the first angle sensor 313 and the second angle sensor 314 after each instruction to the locking control mechanism 42 to lock.

[0079] Please refer to Figure 2 and Figure 3 The fixing member 301 can be a fixing sleeve, which can be installed in the corresponding mounting slot inside the first body 1. The rotary drive member 306, the first engaging member 307, and the second engaging member 308 are all disposed inside the fixing sleeve to protect them and ensure stable operation. The second torque assembly 305 is fixed inside the fixing sleeve so that it does not rotate with the rotation of the bearing 303. The mounting part of the rotating member 302 for connecting to the second body 2 is located outside the fixing sleeve. The sleeve part of the rotating member 302 for sleeved outside the bearing 303, as well as the aforementioned first torque assembly 304, second torque assembly 305, first angle sensor 313, and second angle sensor 314, can all be disposed inside or outside the fixing sleeve as needed.

[0080] In this embodiment, the rotating shaft mechanism 3 is equipped with a first torque component 304 that generates a first torque when the bearing 303 rotates, and a second torque component 305 that is connected to the rotating member 302 and generates a second torque when the rotating member 302 rotates relative to the bearing 303. This ensures that when the rotating drive 306 operates and drives the bearing 303 to rotate via the first engagement member 307 and the second engagement member 308, the rotating member 302 will rotate synchronously with the bearing 303 under the influence of the second torque component 305 (since there is no other force at the rotating member 302 that can overcome the second torque, its rotation is limited by the second torque component 305 connected to it). This also allows the top cover of the electronic device corresponding to the rotating shaft mechanism 3 to be controlled by the rotating drive 306. The opening mechanism requires the rotation to overcome the first torque, thus ensuring a smoother opening of the corresponding electronic device and allowing the top cover to hover at the controlled opening angle. Simultaneously, when the rotation drive 306 is not working, if an external force greater than the second torque is applied to the rotation component 302, the rotation component 302 can disengage from the synchronous state driven by the second torque component 305, generating rotation relative to the bearing 303. This means that the opening angle of the electronic device corresponding to the rotating shaft mechanism 3 is not entirely limited by the rotation drive 306. Users can fine-tune the opening of the top cover of the corresponding electronic device according to their needs after the rotation drive 306 drives it to a certain angle. Alternatively, the top cover of the electronic device can be manually opened in case of a malfunction of the rotation drive 306.

[0081] Example 2

[0082] Please refer to Figure 3 and Figure 5 This is a schematic diagram of the structure of a rotating shaft mechanism 3 provided in this embodiment. The rotating shaft mechanism 3 includes a fixing member 301, a rotating member 302, a bearing 303, a first torque component 304, a second torque component 305, a rotation drive member 306, a first meshing member 307, and a second meshing member 308. A rotating component 302 is sleeved on the outside of a bearing 303; the bearing 303 passes through a fixed component 301 and can rotate relative to the fixed component 301; a first torque component 304 and a second torque component 305 are both sleeved on the outside of the bearing 303, and the second torque component is connected to the rotating component 302; the first torque component 304 is used to generate a first torque when the bearing 303 rotates, and the second torque component 305 is used to generate a second torque when the rotating component 302 rotates relative to the bearing 303; a first engaging component 307 is provided at the output end of the rotating drive component 306, and a corresponding second engaging component 308 is fixed on the outside of the bearing 303; the rotating drive component 306 can drive the bearing 303 to rotate via the first engaging component 307 and the second engaging component 308; the rotating component 302 has a first state in which it rotates synchronously with the bearing 303 when the rotating drive component 306 is working, and a second state in which it rotates relative to the bearing 303 under the drive of an external force greater than the second torque when the rotating drive component 306 is not working.

[0083] Please refer to Figure 3 and Figure 5 The second torque assembly 305 includes a locking member 305a and an elastic member 305b. The locking member 305a is fixedly connected to the bearing 303, and the elastic member 305b is sleeved on the outside of the bearing 303, with one end of the elastic member 305b abutting against the locking member 305a and the other end abutting against the rotating member 302. Specifically, the elastic member 305b can be an elastic sleeve, a compression spring, or a disc spring, etc. The locking member 305a can be a locking nut.

[0084] Please refer to Figure 3 and Figure 5 To improve the rotational stability of the rotating component 302 relative to the bearing 303, a driven component 309 can be provided outside the bearing 303. This driven component 309 is fixedly positioned relative to the rotating component 302 along the circumferential direction of the bearing 303, allowing it to rotate synchronously with the rotating component 302. Specifically, corresponding first fixing grooves 302a and first fixing blocks 309a can be provided on the rotating component 302 and the driven component 309, respectively, so that the driven component 309 and the rotating component 302 are fixedly positioned relative to each other along the circumferential direction of the bearing 303 via the first fixing grooves 302a and the first fixing blocks 309a. It should also be noted that although... Figure 3 and Figure 5 The diagram shows a first fixing groove 302a disposed on the rotating member 302 and a first fixing block 309a disposed on the driven member 309. However, those skilled in the art should understand that the first fixing groove 302a can also be disposed on the driven member 309 and the first fixing block 309a can be disposed on the rotating member 302.

[0085] Please refer to Figure 3 and Figure 5To prevent damage to the rotating member 302 or the driven member 309 caused by the second torque assembly 305 directly abutting against it, and also to generate a certain torque (i.e., the rotating member 302 needs to overcome the torque generated at the first fixing washer 310, the second fixing washer 311, and the third fixing washer 312 when rotating relative to the bearing 303; that is, the first fixing washer 310, the second fixing washer 311, and the third fixing washer 312 can also be considered as components of the second torque assembly 305), a first fixed washer sleeved on the outside of the bearing 303 can be provided. Fixed shims 310, 311, and 312 (or only some of them may be provided) are provided. The first fixed shim 310, the second fixed shim 311, and the third fixed shim 312 are fixedly disposed relative to the bearing 303 along the circumferential and axial directions of the bearing 303. The first fixed shim 310 is disposed between the driven member 309 and the rotating member 302. The second fixed shim 311 is disposed on the side of the driven member 309 away from the rotating member 302. The elastic member 305b abuts against the second fixed shim 311. The third fixed shim 312 is disposed on the side of the rotating member 302 away from the driven member 309.

[0086] It should be noted that the relative fixing of the first fixing shim 310, the second fixing shim 311, and the third fixing shim 312 along the axial direction of the bearing 303 refers to their relative fixing after the shaft mechanism 3 is assembled. During the assembly of the shaft mechanism 3, the first fixing shim 310, the second fixing shim 311, and the third fixing shim 312 can all slide along the axial direction of the bearing 303 to reach the preset position and complete the assembly.

[0087] In addition, a fourth fixing washer 315 may be provided between the elastic member 305b and the locking member 305a.

[0088] Please refer to Figure 3 and Figure 5 The first torque component 304 can be a torque envelope (distinct from the first torque envelope 305A described below; the first torque component 304 can be referred to as a second torque envelope), and it can be as follows: Figure 3 and Figure 5 The image shown is a covered circle with an opening, but it can also be a complete covered circle without an opening.

[0089] Furthermore, all other descriptions of the rotating shaft mechanism 3 in Embodiment 1 above can be incorporated into the rotating shaft mechanism 3 in this embodiment.

[0090] Example 3

[0091] Please refer to Figure 6This is a schematic diagram of the structure of a rotating shaft mechanism 3 provided in this embodiment. The rotating shaft mechanism 3 includes a fixing member 301, a rotating member 302, a bearing 303, a first torque component 304, a second torque component 305, a rotation drive member 306, a first meshing member 307, and a second meshing member 308. A rotating component 302 is sleeved on the outside of a bearing 303; the bearing 303 passes through a fixed component 301 and can rotate relative to the fixed component 301; a first torque component 304 and a second torque component 305 are both sleeved on the outside of the bearing 303, and the second torque component is connected to the rotating component 302; the first torque component 304 is used to generate a first torque when the bearing 303 rotates, and the second torque component 305 is used to generate a second torque when the rotating component 302 rotates relative to the bearing 303; a first engaging component 307 is provided at the output end of the rotating drive component 306, and a corresponding second engaging component 308 is fixed on the outside of the bearing 303; the rotating drive component 306 can drive the bearing 303 to rotate via the first engaging component 307 and the second engaging component 308; the rotating component 302 has a first state in which it rotates synchronously with the bearing 303 when the rotating drive component 306 is working, and a second state in which it rotates relative to the bearing 303 under the drive of an external force greater than the second torque when the rotating drive component 306 is not working.

[0092] Please refer to Figure 6 The second torque component 305 is the first torque envelope 305A, and the rotating component 302 is fixed on the outer circumference of the first torque envelope 305A. Similarly, the first torque envelope 305A can be an envelope with an opening or a complete envelope without an opening.

[0093] At this point, the sleeve portion in the second torque assembly 305 and the rotating member 302 can be considered as the same component.

[0094] In addition, although Figure 6 The first angle sensor 313 and the second angle sensor 314 are not directly shown in the text, but those skilled in the art should understand that the description of the rotating shaft mechanism 3 in the above embodiment 1 can be applied to the rotating shaft mechanism 3 in this embodiment.

[0095] Example 4

[0096] Please refer to Figure 7 and Figure 8This is a schematic diagram of the structure of a rotating shaft mechanism 3 provided in this embodiment. The difference between the rotating shaft mechanism 3 in the above embodiment 3 and the first engaging member 307 and the second engaging member 308 in this embodiment are not directly engaged, but indirectly engaged through a third engaging member 316. The third engaging member 316 includes a first engaging portion 316a and a second engaging portion 316b connected to each other. The first engaging portion 316a engages with the first engaging member 307, and the first engaging portion 316b engages with the second engaging member 308.

[0097] At this time, similar to the first engaging member 307 and the second engaging member 308, the third engaging member 316 is also disposed within the fixing member 301. However, the fixing member 301 in this embodiment is different from the relevant description in Embodiment 1 above. In this embodiment, the fixing of the rotary drive member 306 is not achieved by the fixing member 301 together, but by a set of drive fixing members 317 disposed outside the rotary drive member 306.

[0098] Specifically, the first meshing member 307 can be set as a spur gear, and a spur gear structure can be correspondingly provided on the first meshing part 316a. The second meshing member 308 can be set as a worm gear, and a threaded structure (worm gear structure) can be correspondingly provided on the second meshing part 316b.

[0099] The third meshing member 316 provided in this embodiment can achieve the effect of a speed reducer, thereby improving the opening smoothness of the second body 2.

[0100] Example 5

[0101] Please refer to Figure 9 This is a schematic diagram of the structure of a rotating shaft mechanism 3 provided in this embodiment. The difference between this rotating shaft mechanism 3 and the one in embodiment 4 is that the rotating member 302 in this embodiment is not directly fixed to the outer circumference of the first torque envelope 305A. Instead, the rotating member 302 includes a sleeve portion 302A, a height adjustment portion 302B, and a connecting portion 302C connected in sequence. The sleeve portion 302A is fitted outside the first torque envelope 305A. The height adjustment portion 302B is disposed between the sleeve portion 302A and the connecting portion 302C to increase the distance between the connecting portion 302C and the rotation axis of the bearing 303. The connecting portion 302C is used to connect to the second body 2.

[0102] Furthermore, in order to increase the tightness of the fit between the sleeve portion 302A and the first torque envelope 305A, and to prevent the sleeve portion 302A from rotating relative to the first torque envelope 305A, such as Figure 9As shown, a matching second fixing block 305A1 and a second fixing groove 302A1 can also be provided on the first torque envelope 305A and the sleeve portion 302A respectively, so that the first torque envelope 305A and the sleeve portion 302A are fixedly connected and rotate synchronously.

[0103] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
