Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] With the rapid development of electronic devices, foldable screen electronic devices are becoming increasingly popular among users. Existing foldable screen electronic devices typically consist of a first body and a second body, connected by a hinge. This allows the first and second bodies to open and close relative to each other, enabling the device to switch between an unfolded and folded state. However, the first and second bodies are prone to relative swaying, requiring users to manually control the folding angle. This makes it difficult to suspend the first and second bodies at the desired angle, potentially impacting the user experience. Summary of the Invention

[0003] This application aims to provide an electronic device that at least solves one of the problems in the prior art where it is inconvenient to suspend the first and second bodies of the foldable screen electronic device at the folding angle required by the user, which easily affects the user experience.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides an electronic device, including: a first housing, a second housing, a hinge mechanism, and a locking mechanism, wherein the locking mechanism is disposed on the first housing, and the first housing and the second housing are rotatably connected by the hinge mechanism;

[0006] The locking mechanism includes a driving member, a linkage transmission assembly, and a clamping assembly. The linkage transmission assembly includes multiple hinged links. The clamping assembly includes a clamping part and a connecting part connected to the linkage transmission assembly. The driving member drives the clamping part to move through the linkage transmission assembly, so that the clamping part switches between a locked position and an unlocked position.

[0007] When the clamping part is in the locked position, the clamping assembly abuts against the hinge mechanism to restrict the rotation of the first housing relative to the second housing; when the clamping part is in the unlocked position, the clamping assembly releases the restriction on the clamping mechanism, and the first housing is rotatably connected to the second housing through the hinge mechanism.

[0008] In embodiments of this application, the first housing and the second housing can be rotatably connected via the hinge mechanism, allowing them to be relatively unfolded or folded, thereby enabling the electronic device to switch between unfolded and folded states. The driving member can drive the clamping part to move via a linkage transmission assembly. When the clamping part is in the unlocked position, the clamping assembly can release the restriction on the hinge mechanism, allowing the first housing to be rotatably connected to the second housing via the hinge mechanism, facilitating adjustment of the folding angle between the first and second housings. After determining the folding angle between the first and second housings, the driving member can be used to drive the clamping part to the locked position, causing the clamping assembly to abut against the hinge mechanism to restrict the rotation of the first housing relative to the second housing, thus locking the first and second housings at the desired folding angle and improving the user experience.

[0022] The following is combined Figure 1 - Figure 5 The electronic device described in this application is described.

[0023] like Figure 1 and Figure 2 As shown in some embodiments of this application, an electronic device is proposed, including: a first housing 11, a second housing 12, a hinge mechanism 3, and a locking mechanism 4. The locking mechanism 4 is disposed on the first housing 11, and the first housing 11 and the second housing 12 are rotatably connected by the hinge mechanism 3. The locking mechanism 4 includes a driving member 41, a linkage transmission assembly 43, and a clamping assembly 42. The linkage transmission assembly 43 includes a plurality of hinged links. The clamping assembly 42 may include a clamping part 423 and a connecting part 422 connected to the linkage transmission assembly 43. The driving member 41 drives the clamping part 423 to move through the linkage transmission assembly 43, so that the clamping part 423 switches between a locked position and an unlocked position. When the clamping part 423 is in the locked position, the clamping assembly 42 abuts against the hinge mechanism 3 to restrict the rotation of the first housing 11 relative to the second housing 12. When the clamping part 423 is in the unlocked position, the clamping assembly 42 releases the restriction on the hinge mechanism 3, and the first housing 11 is rotatably connected to the second housing 12 through the hinge mechanism 3.

[0024] In the embodiments of this application, the first housing 11 and the second housing 12 can be rotatably connected by a hinge mechanism 3, allowing the first housing 11 and the second housing 12 to be relatively unfolded or folded, thereby enabling the electronic device to switch between unfolded and folded states. The driving member 41 can drive the clamping part 423 to move via a linkage transmission assembly 43. When the clamping part 423 is in the unlocked position, the clamping assembly 42 can release the restriction on the hinge mechanism 3, allowing the first housing 11 to be rotatably connected to the second housing 12 via the hinge mechanism 3, facilitating adjustment of the folding angle between the first housing 11 and the second housing 12. After determining the folding angle between the first housing 11 and the second housing 12, the driving member 41 can be used to drive the clamping part 423 to the locked position, causing the clamping assembly 42 to abut against the hinge mechanism 3 to restrict the rotation of the first housing 11 relative to the second housing 12, thus locking the first housing 11 and the second housing 12 at the desired folding angle, improving the user experience.

[0025] Specifically, in this embodiment, the locking mechanism 4 can switch between a locked state and an unlocked state. When the clamping part 423 is in the locked position, the locking mechanism 4 can switch to the locked state; when the clamping part 423 is in the unlocked position, the locking mechanism 4 can switch to the unlocked state, so that the first housing 11 and the second housing 12 can be fixed at any folding angle, which can improve the stability of the electronic device and the user experience. Moreover, the locking mechanism 4 has a simple structure, low cost, and high feasibility.

[0026] The electronic devices described in this application embodiment include, but are not limited to, mobile phones, tablets, laptops, smart wearable devices, game consoles, etc., and can be set according to actual needs. This application embodiment does not make specific limitations in this regard.

[0027] Specifically, the electronic device includes a first housing 11 and a second housing 12 rotatably connected by a hinge mechanism 3. When the first housing 11 and the second housing 12 are folded relative to each other, the electronic device can be in a folded state, which is small in size and easy to carry and store. When the first housing 11 and the second housing 12 are unfolded relative to each other, the electronic device can be in an unfolded state, which has a larger display area and is easy to display.

[0028] The hinge mechanism 3 described in this embodiment is disposed between the first housing 11 and the second housing 12. The hinge mechanism 3 may also include only one set of hinge components 31. The hinge component 31 may include a rotating shaft 311 and a swing arm 312. The swing arm 312 may be fixedly connected to the first housing 11, and the rotating shaft 311 may be fixedly connected to the second housing 12. The swing arm 312 is sleeved on the rotating shaft 311 and can rotate around the rotating shaft 311, thereby realizing the rotational connection between the first housing 11 and the second housing 12.

[0029] Alternatively, the hinge mechanism 3 may include a connecting plate and two sets of hinge assemblies 31 respectively disposed on opposite sides of the connecting plate. The two sets of hinge assemblies 31 may include a first hinge assembly and a second hinge assembly. The first hinge assembly is rotatably connected to the connecting plate and the first housing 11 respectively, so that the folding angle of the first housing 11 can be adjusted. The second hinge assembly is rotatably connected to the connecting plate and the second housing 12 respectively, so that the folding angle of the second housing 12 can be adjusted. In this way, under the combined action of the first hinge assembly and the second hinge assembly, the folding angle between the first housing 11 and the second housing 12 can be adjusted, making it easy to realize that the electronic device can present any folding angle.

[0030] Optionally, such as Figure 4 As shown, the hinge mechanism 3 includes two sets of hinge components 31. The hinge mechanism 3 also includes a first gear 315 disposed on one of the rotating shafts 311, a second gear 321 disposed on the other rotating shaft 311, and a synchronous gear set 33. The synchronous gear set 33 includes a third gear 331 and a fourth gear 332 that move synchronously and in opposite directions. The third gear 331 is meshed with the first gear 315, and the fourth gear 332 is meshed with the second gear 321, so that the first gear 315 and the second gear 321 move synchronously and in opposite directions, thereby enabling the two sets of hinge components 31 to move synchronously and in opposite directions, and the first housing 11 and the second housing 12 to rotate synchronously and in opposite directions.

[0031] Furthermore, when both sets of hinge assemblies are locked simultaneously, the first housing 11 and the second housing 12 are relatively fixed; when one set of hinge assemblies is unlocked, the folding angle between the first housing 11 and the second housing 12 can be adjusted.

[0032] The locking mechanism 4 described in this embodiment can be disposed in the first housing 11, and may specifically include a driving member 41, a linkage transmission assembly 43 and a clamping assembly 42; the driving member 41 can be connected to the clamping assembly 42 through the linkage transmission assembly 43.

[0033] Specifically, the linkage transmission assembly 43 may include multiple hinged links. The number of links may be two, three, four, or five, etc., and can be set according to actual needs. This application embodiment does not specifically limit this.

[0034] Specifically, the clamping assembly 42 may include a clamping part 423 and a connecting part 422 connected to the linkage drive assembly 43; specifically, the clamping part 423 may be disposed on the side of the connecting part 422 away from the linkage drive assembly 43, so that the linkage drive assembly 43 can drive the clamping part 423 to switch between a locked position and an unlocked position through the connecting part 422.

[0035] Specifically, the connecting part 422 and the clamping part 423 can be fixed by means of bonding, welding or bolting; the connecting part 422 and the clamping part 423 can also be an integrally formed structure, which can be set according to actual needs, and this application embodiment does not make specific limitations in this regard.

[0036] Furthermore, the driving component 41 can drive the linkage transmission assembly 43 to move. The linkage transmission assembly 43 can drive the clamping part 423 to move through the connecting part 422, thereby causing the clamping part 423 to switch between a locked position and an unlocked position. When the clamping part 423 is in the locked position, the clamping assembly 42 abuts against the hinge mechanism 3 and can restrict the movement of the hinge mechanism 3, so that the hinge mechanism 3 is fixed, thereby ensuring that the first housing 11 and the second housing 12 are relatively fixed. When the clamping part 423 is in the unlocked position, the clamping assembly 42 can release the restriction on the hinge mechanism 3, so that the hinge mechanism 3 can rotate, thereby adjusting the folding angle between the first housing 11 and the second housing 12.

[0037] Optionally, when the clamping part 423 is in the locked position, the connecting rod connected to the drive member 41 is in the first extreme position, so that the connecting rod transmission assembly 43 is in a locked state.

[0038] In this embodiment, when the clamping part 423 is in the locked position, the linkage transmission assembly 43 is in a locked state. In this way, when the driving member 41 stops driving, the linkage transmission assembly 43 can lock the position of the clamping part 423, so that the clamping part 423 can be locked in the locked position, which can improve the reliability of restricting the rotation of the first housing 11 relative to the second housing 12.

[0039] Specifically, the linkage transmission assembly 43 includes a locked state and an unlocked state. In the locked state, the link connected to the drive member 41 in the linkage transmission assembly 43 moves to a first limit position, causing the linkage transmission assembly 43 to be in a dead position. The drive member 41 can output a thrust hundreds of times greater than its own thrust through the linkage transmission assembly 43 in the locked state, so as to ensure that the clamping part 423 can achieve reliable limiting, thereby restricting the movement of the first housing 11 relative to the second housing 12. In the unlocked state, the link in the linkage transmission assembly 43 releases the restriction on the clamping part 423, and the clamping part 423 releases the restriction on the hinge mechanism 3. The first housing 11 rotates relative to the second housing 12 through the hinge mechanism 3.

[0040] Specifically, such as Figure 2 As shown, when the connecting rod 44 connected to the drive component 41 is in the first extreme position, the linkage transmission assembly 43 can be switched to the locked state; as Figure 3 As shown, when the adapter link 44 connected to the drive component 41 leaves the first limit position, the link transmission assembly 43 can be switched to the unlocked state.

[0041] Optionally, the linkage drive assembly 43 can be disposed between the clamping assembly 42 and the driving member 41, with the clamping part 423 fixedly connected to the connecting part 422; the linkage drive assembly 43 may include a first clamping connecting part, a second clamping connecting part and a driving connecting part, the first clamping connecting part being connected to the connecting part 422 located on one side of the clamping part 423, and the second clamping connecting part being connected to the connecting part 422 located on the other side of the clamping part 423; the driving connecting part 422 is located between the first clamping connecting part and the second clamping connecting part and is connected to the driving member 41.

[0042] In this embodiment, the drive connection portion 422 is located between the first clamping connection portion and the second clamping connection portion and is connected to the drive member 41, so that the drive member 41 drives the first clamping connection portion and the second clamping connection portion to move respectively through the drive connection portion 422. Since the first clamping connection portion is connected to the connection portion located on one side of the clamping portion 423, and the second clamping connection portion is connected to the connection portion 422 located on the other side of the clamping portion 423, the first clamping connection portion and the second clamping connection portion can apply driving force to the connection portion 422 from both sides of the clamping portion 423, which can improve the smoothness of the movement of the clamping portion 423 driven by the connection portion 422.

[0043] Specifically, the linkage transmission assembly 43 is disposed between the clamping assembly 42 and the driving member 41, so that the driving member 41 can drive the clamping assembly 42 to move through the linkage transmission assembly 43.

[0044] Specifically, the first clamping connection may include one, two, or three connecting rods, and the second clamping connection may include one, two, or three connecting rods, etc. The specific configuration can be determined according to actual needs, and this application embodiment does not impose any specific limitations on this.

[0045] Specifically, such as Figure 2 As shown, the first clamping connection may include a first link 431, a second link 432 and a third link 433, and the second clamping connection may include a fourth link 434, a fifth link 435 and a sixth link 436. Other configurations can be referenced.

[0046] Optionally, the drive connection portion is opposite to the clamping portion 423, and the moving direction of the drive connection portion is the same as the moving direction of the clamping assembly 42; in the moving direction perpendicular to the clamping assembly 42, the clamping portion 423 is located at the middle position of the first clamping connection portion and the second clamping connection portion, and the drive connection portion may be located at the middle position of the first clamping connection portion and the second clamping connection portion.

[0047] In this embodiment, in the direction of movement perpendicular to the clamping assembly 42, the clamping part 423 is located at the middle position of the first clamping connecting part and the second clamping connecting part, and the driving connecting part is located at the middle position of the first clamping connecting part and the second clamping connecting part, so that the two sides of the clamping part 423 are subjected to the same force, which can improve the reliability and convenience of the driving connecting part in transmitting the driving force to the first clamping connecting part and the second clamping connecting part respectively, thereby improving the stability of the connecting part 422 driving the clamping part 423 to move.

[0048] In an optional embodiment of this application, the locking mechanism 4 may further include a fixed bracket 45. The linkage transmission assembly 43 includes a first link 431, a second link 432, a third link 433, a fourth link 434, a fifth link 435, a sixth link 436, and a transition link 44. The fixed bracket 45 is fixedly connected to the first housing 11, and the transition link 44 is connected to the drive member 41. One end of the first link 431 is rotatably connected to the connecting part 422, and the other end is hinged to the second link 432 via the first pin 51. The end of the second link 432 away from the first link 431 is hinged to the fixed bracket 45. One end of the fourth link 434 is rotatably connected to the connecting part 422, and the other end is hinged to the fifth link 435 via the second pin 52. The end of the fifth link 435 away from the fourth link 434 is hinged to the fixed bracket 45. One end of the third link 433 is rotatably connected to the first pin 51, and the other end is hinged to one end of the transition link 44. One end of the sixth link 436 is rotatably connected to the second pin 52, and the other end is hinged to the other end of the transition link 44.

[0049] In this embodiment, the driving member 41 can drive the transition link 44 to move. The transition link 44 can drive the third link 433 and the sixth link 436 to move, and then drive the first pin 51 and the second pin 52 to move. The first pin 51 can drive the first link 431 and the second link 432 to move, and the second pin 52 can drive the fourth link 434 and the fifth link 435 to move. Since the fixed bracket 45 is fixedly connected to the first housing 11, the first link 431 and the fourth link 434 can drive the connecting part 422 to move, thereby realizing the switching of the clamping part 423 between the locked position and the unlocked position.

[0050] Specifically, the fixing bracket 45 can be fixed to the first housing 11 by screws, or by adhesive or welding. The specific setting can be made according to actual needs, and this application embodiment does not make specific limitations in this regard.

[0051] Specifically, the first link 431 and the third link 433 are respectively located on both sides of the transition link 44; the second link 432 and the fifth link 435 are respectively located on both sides of the transition link 44.

[0052] Specifically, the first link 431 is hinged to the connecting part 422 via the third pin 53, the second link 432 is hinged to the fixed bracket 45 via the fourth pin 54, the fourth link 434 is hinged to the connecting part 422 via the fifth pin 55, and the fifth link 435 is hinged to the fixed bracket 45 via the sixth pin 56. When the clamping part 423 is in the locked position, the first pin 51, the first link 431, the third pin 53, the second link and the fourth pin 54 are on the same straight line, and the second pin 52, the fourth link 434, the fifth pin 55, the fifth link 435 and the sixth pin 56 are on the same straight line, so that the link transmission assembly 43 is in the dead point position.

[0053] Specifically, when the clamping part 423 is in the locked position, the third link 433, the transition link 44 and the sixth link 436 are on the same straight line and can be perpendicular to the first link 431.

[0054] Specifically, such as Figure 3 As shown, the driving component 41 drives the adapter link 44 to move closer to the center. Figure 2 During the movement to the first extreme position shown, the clamping part 423 moves from the unlocked position to the locked position. The connecting rod 44 drives the third connecting rod 433 and the sixth connecting rod 436 upwards respectively; the third connecting rod 433 drives the first connecting rod 431 and the second connecting rod 432 outwards and drives the first connecting rod 431 upwards; the sixth connecting rod 436 drives the fourth connecting rod 434 and the fifth connecting rod 435 outwards and drives the fourth connecting rod 434 upwards; the first connecting rod 431 and the fourth connecting rod 434 together drive the connecting part 422 upwards, and the connecting part 422 drives the clamping part 423 upwards, as shown... Figure 2 As shown, when the clamping part 423 is switched to the locking position, the first link 431 and the second link 432 are on the same straight line and perpendicular to the third link 433; the fourth link 434 and the fifth link 435 are on the same straight line and perpendicular to the sixth link 436, so that the link transmission assembly 43 is in the dead point position, the clamping part 423 can firmly press the hinge mechanism 3, so that the hinge mechanism 3 cannot move, thereby fixing the first housing 11 relative to the second housing 12.

[0055] Specifically, during the movement of the clamping part 423 from the locked position to the unlocked position, the driving member 41 drives the transition link 44 to move away from the first limit position. The transition link 44 drives the third link 433 and the sixth link 436 to move downwards respectively. The third link 433 drives the first link 431 and the second link 432 to move, and the sixth link 436 drives the fourth link 434 and the fifth link 435 to move, so that the linkage transmission assembly 43 crosses the dead point position. The clamping assembly 42 can release the restriction on the hinge mechanism 3. The hinge mechanism 3 is unlocked, and the movement of the linkage transmission assembly 43 is no longer constrained. The first housing 11 can rotate freely relative to the second housing 12.

[0056] The adapter link 44 has a first extreme position and a second extreme position away from the first extreme position during its movement. As the clamping part 423 switches between the locked and unlocked positions, the adapter link 44 moves between the first and second extreme positions. As the clamping part 423 moves from the locked position to the unlocked position, the drive member 41 drives the adapter link 44 to move from the first extreme position to the second extreme position. The second extreme position is closer to the drive member 41 than the first extreme position. When the adapter link 44 moves to the second extreme position, the clamping assembly 42 releases the restriction on the hinge mechanism 3.

[0057] Optionally, the drive unit 41 may include a motor 411 and a motor shaft 412; one end of the motor shaft 412 is telescopically connected to the motor 411, and the other end of the motor shaft 412 is fixedly connected to the adapter rod 44, and the motor 411 drives the adapter rod 44 to move through the motor shaft 412.

[0058] Specifically, the motor 411 can be fixedly connected to the first housing 11, or the motor can be fixedly connected to the fixed bracket 45. One end of the motor shaft 412 is fixed to the adapter rod 44, and the other end is telescopically connected to the motor 411, so that the telescopic movement of the motor shaft 412 can drive the adapter rod 44 to move. Further, when the motor shaft 412 is retracted into the motor 411, the adapter rod 44 can drive the clamping part 423 to switch to the unlocked position through the linkage transmission assembly 43; when the motor shaft 412 extends out of the motor 411, the adapter rod 44 can drive the clamping part 423 to switch to the locked position through the linkage transmission assembly 43.

[0059] Specifically, the motor 411 can be the power device of the locking mechanism 4, specifically a stepper motor or a servo motor, etc., which can be set according to actual needs. This application embodiment does not make specific limitations in this regard.

[0060] Specifically, the motor shaft 412 can be connected to the center position of the adapter link 44, or it can be connected to one end of the adapter link 44. The specific configuration can be determined according to actual needs, and this embodiment does not impose any specific limitations on this. The adapter link 44 can transmit the thrust or pull force of the motor 411 to the third link 433 and the sixth link 436. Furthermore, when the linkage transmission assembly 43 is in the dead position, the motor 411 outputs a larger thrust, allowing the clamping part 423 to firmly clamp the hinge mechanism 3.

[0061] Specifically, in this embodiment, the working mode of the motor 411 can be controlled by the application program in the electronic device, so that the motor 411 can automatically control the locking mechanism 4 without the need for manual buttons. This reduces the number of openings in the housing, provides better waterproof performance, makes the structure of the electronic device more complete and aesthetically pleasing, and also improves the ease of operation.

[0062] Alternatively, the motor 411 can also be replaced by a cylinder, which can be set according to actual needs. This application does not impose specific limitations on this.

[0063] Optionally, the locking mechanism 4 may further include a first guide rail 61 and a second guide rail 62; the first guide rail 61 and the second guide rail 62 are fixed at a distance from the first housing 11, and both the first guide rail 61 and the second guide rail 62 extend along the moving direction of the clamping part 423; the connecting part 422 is located between the first guide rail 61 and the second guide rail 62, one end of the connecting part 422 is limited to the first guide rail 61, and the other end of the connecting part 422 is limited to the second guide rail 62.

[0064] In this embodiment, one end of the connecting part 422 is limited to the first guide rail 61, and the other end is limited to the second guide rail 62, so that the first guide rail 61 and the second guide rail 62 are respectively disposed at both ends of the connecting part 422. Since the first guide rail 61 and the second guide rail 62 both extend along the moving direction of the clamping part 423, the guiding effect of the first guide rail 61 and the second guide rail 62 on the connecting part 422 can be improved, and the reliability of the clamping part 423 switching between the locked position and the unlocked position can be improved.

[0065] Specifically, the first guide rail 61 can be fixed to the first housing 11 by screws, or by bonding or welding; the second guide rail 62 can be fixed to the first housing 11 by screws, or by bonding or welding. The way the first guide rail 61 and the second guide rail 62 are fixed to the first housing 11 can be set according to actual needs, and this application embodiment does not specifically limit this.

[0066] In some alternative embodiments of this application, the locking mechanism 4 may further include a limiting rod 46, which may be connected to the hinge mechanism 3. The clamping assembly 42 may further include a fixing part 421. The driving member 41 pushes the clamping part 423 to move between a locked position near the fixing part 421 and an unlocked position away from the fixing part 421 through the linkage transmission assembly 43. When the clamping part 423 is in the locked position, the clamping part 423 and the fixing part 421 clamp and fix the limiting rod 46 from both sides, thereby restricting the rotation of the hinge mechanism 3.

[0067] In this embodiment, the limiting rod 46 is clamped from both sides by the fixing part 421 and the clamping part 423, which can effectively fix the limiting rod 46 and thus restrict the rotation of the hinge mechanism 3, thereby improving the convenience and reliability of the locking mechanism 4 in restricting the movement of the hinge mechanism 3.

[0068] Specifically, the fixing part 421 can be fixedly connected to the first housing 11. Specifically, it can be fixed to the first housing 11 by screws, or it can be fixed to the first housing 11 by adhesive or welding. The specific configuration can be set according to actual needs, and this application embodiment does not make specific limitations in this regard.

[0069] Specifically, the clamping part 423 can be disposed opposite to the fixing part 421, and the clamping part 423 can move between a locked position close to the fixing part 421 and an unlocked position away from the fixing part 421.

[0070] Optionally, the limiting rod 46 may include a first limiting connecting rod 461 and a second limiting connecting rod 462. One end of the first limiting connecting rod 461 is rotatably connected to the hinge mechanism 3, and the other end of the first limiting connecting rod 461 may be hinged to the second limiting connecting rod 462. When the clamping part 423 is in the locked position, the clamping part 423 and the fixing part 421 cooperate to clamp the second limiting connecting rod 462 to restrict the movement of the second limiting connecting rod 462. When the clamping part 423 is in the unlocked position, the clamping part 423 separates from the second limiting connecting rod 462.

[0071] In this embodiment, the clamping part 423 and the fixing part 421 cooperate to clamp the second limiting connecting rod 462, and the movement of the hinge mechanism 3 can be restricted by restricting the movement of the second limiting connecting rod 462; the separation of the clamping part 423 from the second limiting connecting rod 462 can also release the restriction on the hinge mechanism 3.

[0072] Specifically, the hinge mechanism 3 may include a rotating shaft 311 and a swing arm 312; the swing arm 312 is sleeved outside the rotating shaft 311 and is rotatably connected to the rotating shaft 311; the swing arm 312 is fixedly connected to the first housing 11; the rotating shaft 311 is rotatably connected to the end of the first limiting connecting rod 461 away from the second limiting connecting rod 462, so that after the second limiting connecting rod 462 is restricted, the first limiting connecting rod 461 can be fixed, thereby driving the rotating shaft 311 to be fixed, so that the first housing 11 is fixed relative to the second housing 12.

[0073] Specifically, a slide rail may be provided on the first housing 11 so that the second limiting connecting rod 462 can slide along the slide rail, thereby improving the reliability of the second limiting connecting rod 462 slidingly connected to the first housing 11.

[0074] Optionally, the locking mechanism 4 further includes two guide members 47, which can be arranged opposite to each other and are both fixedly connected to the first housing 11; the guide member 47 has a through hole for the second limiting connecting rod 462 to slide along the through hole.

[0075] Specifically, when the folding angle between the first housing 11 and the second housing 12 reaches the user's desired angle, the locking mechanism 4 can be activated with a single click via an application in the electronic device, such as... Figure 3 As shown, motor 411 can drive motor shaft 412 to extend, causing adapter link 44 to drive third link 433 and sixth link to unfold to both sides. Third link 433 pushes second link 432 and first link 431 to straighten, and sixth link 436 pushes fourth link 434 and fifth link 435 to straighten. During the straightening process of first link 431, clamping assembly 42 can be pushed to move forward along first guide rail 61. During the straightening process of sixth link 436, clamping assembly 42 can be pushed to move forward along second guide rail 62. After the clamping part 423 contacts the second limiting connecting rod 462, the clamping part 423 and the fixing part 421 squeeze the second limiting connecting rod 462. As the third link 433 and the sixth link 436 continue to unfold, the clamping force on the second limiting connecting rod 462 continues to increase. When the third link 433 is fully unfolded, the clamping force on the second limiting connecting rod 462 reaches its maximum. Under this condition, the clamping force on the second limiting connecting rod 462 can lock the second limiting connecting rod 462 and prevent the second limiting connecting rod 462 from sliding. Furthermore, the first limiting connecting rod 461 locks the rotating shaft 311 to achieve the fixation of the first housing 11 and the second housing 12.

[0076] Optionally, the clamping part 423 has a first limiting recess, and the fixing part 421 may have a second limiting recess; when the clamping part 423 is in the locked position, the first limiting recess and the second limiting recess are opposite to each other to limit the second limiting connecting rod 462, and the shapes of the first limiting recess and the second limiting recess match the second limiting connecting rod 462.

[0077] In this embodiment of the application, the first limiting recess and the second limiting recess are used to limit the second limiting connecting rod 462, which can improve the reliability of the clamping part 423 and the fixing part 421 in fixing the second limiting connecting rod 462.

[0078] Specifically, the shape of the first limiting recess matches the shape of the second limiting connecting rod 462, and the shape of the second limiting recess matches the shape of the second limiting connecting rod 462. For example, the second limiting connecting rod 462 is a circular rod, and the corresponding first and second limiting recesses are both arc-shaped structures; or, the second limiting connecting rod 462 is a square rod, and the corresponding first and second limiting recesses are both square structures. The specific design can be adjusted according to actual needs, and this embodiment does not impose specific limitations on this.

[0079] Furthermore, anti-slip pads can be provided on the inner walls of the first and second limiting recesses to increase the coefficient of friction between the first and second limiting recesses and the second limiting connecting rod 462. This allows the anti-slip pads to deform and better hold the second limiting connecting rod 462 during the clamping process using the first and second limiting recesses, while also preventing damage to the second limiting connecting rod 462. The anti-slip pads can be one of rubber, plastic, or latex pads.

[0080] Optionally, the hinge mechanism 3 may include a pivot 311, and a clamping part 423 is disposed opposite to the pivot 311. When the clamping part 423 is in the locked position, the clamping part 423 abuts against the pivot 311 to restrict the rotation of the pivot 311. When the clamping part 423 is in the unlocked position, the clamping part 423 separates from the pivot 311 to release the restriction on the pivot 311.

[0081] In this embodiment, the clamping part 423 abuts against the rotating shaft 311 to restrict the rotation of the rotating shaft 311, thereby fixing the hinge mechanism 3 and fixing the first housing 11 relative to the second housing 12; the clamping part 423 separates from the rotating shaft 311 to release the rotating shaft 311, thereby releasing the restriction on the hinge mechanism 3 and allowing the first housing 11 to rotate relative to the second housing 12 through the hinge mechanism 3.

[0082] Specifically, such as Figure 5As shown, the hinge mechanism 3 may include a swing arm 312; the swing arm 312 is sleeved on the outside of the rotating shaft 311, the swing arm 312 is rotatably connected to the rotating shaft 311, and the swing arm 312 is fixedly connected to the first housing 11; when the clamping part 423 is switched to the locked position, the clamping part 423 abuts against and locks the rotating shaft 311; when the clamping part 423 is switched to the unlocked position, the clamping part 423 separates from the rotating shaft 311 and unlocks the rotating shaft 311.

[0083] Specifically, the swing arm 312 can be bolted to the first housing 11 using screws, or it can be fixed to the first housing 11 by means of bonding or welding. The specific configuration can be set according to actual needs, and this application embodiment does not make specific limitations in this regard.

[0084] Specifically, when the folding angle between the first housing 11 and the second housing 12 reaches the user's desired angle, the locking mechanism 4 can be activated with a single key press via the application in the electronic device. The motor 411 can drive the motor shaft 412 to extend, causing the connecting rod 44 to drive the third connecting rod 433 and the sixth connecting rod 436 to unfold to both sides. The third connecting rod 433 pushes the second connecting rod 432 and the first connecting rod 431 on both sides to straighten, and the sixth connecting rod 436 pushes the fourth connecting rod 434 and the fifth connecting rod 435 to straighten. During the straightening process of the first connecting rod 431, the connecting part 422 can be pushed forward along the first guide rail 61. During the straightening process of the fourth connecting rod 434, the connecting part 422 can be pushed forward along the second guide rail 62. After the clamping part 423 contacts the rotating shaft 311, the clamping part 423 begins to squeeze the rotating shaft 311. As the third link 433 and the sixth link 436 continue to unfold, the clamping force on the rotating shaft 311 from the clamping part 423 continues to increase. When the third link 433 and the sixth link 436 are fully unfolded, the clamping force on the rotating shaft 311 reaches its maximum. Under this condition, the clamping force on the rotating shaft 311 can lock the rotating shaft 311 and prevent the rotating shaft 311 from sliding, thereby locking the hinge mechanism 3 to achieve the fixation of the first housing 11 and the second housing 12.

[0085] Specifically, when the clamping part 423 is in the locked position, the third link 433, the sixth link 436 and the transition link 44 are collinear, and the first link 431 and the second link 432 are collinear and perpendicular to the third link 433. At this time, the linkage transmission assembly 43 is in the dead position and does not change the position of the linkage transmission assembly 43. The clamping assembly 42 can apply a constant clamping force to the rotating shaft 311. Therefore, after the clamping part 423 reaches the locked position, the power to the motor 411 can be cut off.

[0086] Specifically, when unlocking the first housing 11 and the second housing 12, the locking mechanism 4 can be activated with a single click via an application in the electronic device. The motor 411 drives the motor shaft 412 to retract, causing the connecting rod 44 to retract the third connecting rod 433 and the sixth connecting rod 436. The connecting part 422 moves backward along the first guide rail 61 and the second guide rail 62, allowing the linkage transmission assembly 43 to cross the dead point position. The clamping part 423 separates from the rotating shaft 311, allowing the rotating shaft 311 to rotate freely. The folding angle between the first housing 11 and the second housing 12 can be adjusted. The motor 411 can stop working after the motor shaft 412 is fully retracted.

[0087] The electronic device described in this application has at least the following advantages:

[0088] In embodiments of this application, the first housing and the second housing can be rotatably connected via the hinge mechanism, allowing them to be relatively unfolded or folded, thereby enabling the electronic device to switch between unfolded and folded states. The driving member can drive the clamping part to move via a linkage transmission assembly. When the clamping part is in the unlocked position, the clamping assembly can release the restriction on the hinge mechanism, allowing the first housing to be rotatably connected to the second housing via the hinge mechanism, facilitating adjustment of the folding angle between the first and second housings. After determining the folding angle between the first and second housings, the driving member can be used to drive the clamping part to the locked position, causing the clamping assembly to abut against the hinge mechanism to restrict the rotation of the first housing relative to the second housing, thus locking the first and second housings at the desired folding angle and improving the user experience.
