Technical Field

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

[0002] In related technologies, tri-fold screen electronic devices include a first body, a second body, and a third body connected together. When unfolding the electronic device, it is necessary to operate the electronic device with both hands. Specifically, after the left hand pries open the first body, the right hand needs to pry open the third body from below. The opening method is inconvenient, and the third body is difficult to pry open due to its awkward angle, which is very unfriendly to users. Summary of the Invention

[0003] This application aims to provide an electronic device that solves the problem of inconvenient unfolding process of electronic devices.

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

[0005] This application provides an electronic device comprising: a first folding section, a second folding section, a third folding section, and a linkage mechanism; the first folding section, the second folding section, and the third folding section are connected in sequence; the electronic device has a folded state and an unfolded state, wherein in the folded state, the first folding section, the second folding section, and the third folding section are stacked; in the unfolded state, any one of the first folding section, the second folding section, and the third folding section unfolds relative to its adjacent counterpart; the linkage mechanism is connected to the first folding section, the second folding section, and the third folding section, during which the first folding section rotates relative to the second folding section, drives the third folding section to rotate relative to the second folding section, thereby switching the electronic device between the folded state and the unfolded state.

[0006] In the embodiments of this application, the electronic device includes a first folding section, a second folding section, a third folding section, and a linkage mechanism. The first folding section, the second folding section, and the third folding section are connected in sequence, and both the first folding section and the third folding section are rotatable relative to the second folding section. The linkage mechanism is connected to the first folding section, the second folding section, and the third folding section. During the rotation of the first folding section relative to the second folding section, the linkage mechanism moves, causing the third folding section to rotate relative to the second folding section. Thus, during the unfolding and folding of the electronic device, the opening and closing of the electronic device can be achieved through the linkage of the linkage mechanism, without the need to operate the first folding section and the third folding section separately, making the opening and closing of the electronic device more convenient.

[0029] The following is combined Figures 1-14 This application describes an electronic device according to an embodiment of the present application.

[0030] like Figure 1 , Figure 2 and Figure 12 As shown, an electronic device according to some embodiments of this application includes: a first folding part 1, a second folding part 2, a third folding part 3, and a linkage mechanism 4; the first folding part 1, the second folding part 2, and the third folding part 3 are connected in sequence; the electronic device has a folded state and an unfolded state. In the folded state, the first folding part 1, the second folding part 2, and the third folding part 3 are stacked; in the unfolded state, any one of the first folding part 1, the second folding part 2, and the third folding part 3 unfolds relative to the adjacent one; the linkage mechanism 4 is connected to the first folding part 1, the second folding part 2, and the third folding part 3. During the rotation of the first folding part 1 relative to the second folding part 2, the linkage mechanism 4 drives the third folding part 3 to rotate relative to the second folding part 2, so that the electronic device switches between the folded state and the unfolded state.

[0031] In the embodiments of this application, the electronic device includes a first folding part 1, a second folding part 2, a third folding part 3, and a linkage mechanism 4. The first folding part 1, the second folding part 2, and the third folding part 3 are connected in sequence, and both the first folding part 1 and the third folding part 3 are rotatable relative to the second folding part 2. The linkage mechanism 4 is connected to the first folding part 1, the second folding part 2, and the third folding part 3. During the rotation of the first folding part 1 relative to the second folding part 2, the linkage mechanism 4 moves, causing the third folding part 3 to rotate relative to the second folding part 2. Thus, during the unfolding and folding of the electronic device, the opening and closing of the electronic device can be achieved through the linkage of the linkage mechanism 4, without the need to operate the first folding part 1 and the third folding part 3 separately, making the opening and closing of the electronic device more convenient.

[0032] Specifically, in the folded state, the first fold 1, the second fold 2, and the third fold 3 are stacked. In the unfolded state, any one of the first fold 1, the second fold 2, and the third fold 3 unfolds relative to its adjacent counterpart. Thus, during the process of switching the electronic device from the folded state to the unfolded state, the first fold 1 rotates relative to the second fold 2 towards the unfolded position, and the linkage mechanism 4 drives the third fold 3 to rotate relative to the second fold 2, causing the first fold 1 and / or the third fold 3 to unfold relative to the second fold 2. During the process of switching the electronic device from the unfolded state to the folded state, the first fold 1 rotates relative to the second fold 2 towards the folded position, and the linkage mechanism 4 drives the third fold 3 to rotate relative to the second fold 2, thereby causing the first fold 1 and the third fold 3 to fold relative to the second fold 2.

[0033] It is understandable that during the switching between the unfolded and folded states of the electronic device, the third folding part 3 may move relative to the second folding part 2, and the first folding part 1 may move relative to the second folding part 2 through the linkage mechanism 4, so that the electronic device is in the unfolded or folded state.

[0034] It should be noted that when any one of the first folding section 1, the second folding section 2, and the third folding section 3 is unfolded relative to its adjacent counterpart, including when the first folding section 1 is unfolded relative to the second folding section 2, and when the third folding section 3 is unfolded relative to the second folding section 2, the first folding section 1 unfolding relative to the second folding section 2 includes having an angle between the two sections, specifically, the angle is greater than 0° and less than or equal to 180°. Similarly, when the third folding section 3 is unfolded relative to the second folding section 2, the third folding section 3 unfolding relative to the second folding section 2 includes having an angle between the two sections, specifically, the angle is greater than 0° and less than or equal to 180°.

[0035] In practical applications, the first folding part 1 is rotatably connected to the second folding part 2, and the third folding part 3 is rotatably connected to the second folding part 2.

[0036] It is understood that at least two of the first folding part 1, the second folding part 2, and the third folding part 3 can be rotated relative to each other by the user to drive the other one through the linkage mechanism 4, or the linkage mechanism 4 can be driven by the drive mechanism to move, so that the first folding part 1 and the third folding part 3 move relative to the second folding part 2.

[0037] In specific applications, when the electronic device is in a folded state, the first fold 1 and the third fold 3 are located on opposite sides of the second fold 2, forming a Z-shaped fold; or the first fold 1 and the third fold 3 can be located on the same side of the second fold 2. Specifically, the first fold 1 is located between the third fold 3 and the second fold 2, or the second fold 2 is located between the first fold 1 and the third fold 3.

[0038] like Figures 2 to 6 As shown, according to some embodiments of this application, the linkage mechanism 4 includes a first linkage part 40, which is connected to the first folding part 1, the second folding part 2 and the third folding part 3 to drive the first folding part 1 and the third folding part 3 to rotate at the same angle relative to the second folding part 2. The unfolded state includes a first state in which the first folding part 1, the second folding part 2 and the third folding part 3 are laid flat.

[0039] In this embodiment, such as Figure 3 and Figure 4As shown, the linkage mechanism 4 includes a first linkage part 40, which is connected to the first folding part 1, the second folding part 2, and the third folding part 3. The first linkage part 40 drives the first folding part 1, the second folding part 2, and the third folding part 3 to move, so that the first folding part 1 and the third folding part 3 rotate at the same angle relative to the second folding part 2, thereby achieving synchronous unfolding of the first folding part 1 and the third folding part 3, allowing the electronic device to switch between a folded state and a first state. That is, as... Figure 5 and Figure 6 As shown, the first linkage part 40 can drive the first folding part 1, the second folding part 2 and the third folding part 3 to be fully unfolded so as to display through the first folding part 1, the second folding part 2 and the third folding part 3, thereby realizing the large display screen mode of the electronic device.

[0040] It is understood that the electronic device also includes a damping mechanism, which is connected to the first folding part 1, the second folding part 2 and the third folding part 3, so that the first folding part 1 can be suspended relative to the second folding part 2 and the third folding part 3 can be suspended relative to the second folding part 2. Then, through the drive of the first linkage part 40, the first folding part 1 and the third folding part 3 can be suspended to different positions with the same rotation angle, so that the electronic device has multiple unfolding postures to adapt to different usage scenarios.

[0041] With the second folding part 2 as a reference, under the drive of the first linkage part 40, the first folding part 1 rotates at the same angle relative to the second folding part 2 as the third folding part 3 rotates at the same angle relative to the second folding part 2.

[0042] like Figures 7 to 11 As shown, according to some embodiments of this application, the linkage mechanism 4 includes a second linkage part 42, which is connected to the first folding part 1, the second folding part 2 and the third folding part 3 to drive the first folding part 1 and the third folding part 3 to rotate at different angles relative to the second folding part 2.

[0043] In this embodiment, the linkage mechanism 4 includes a second linkage part 42, which is connected to the first folding part 1, the second folding part 2 and the third folding part 3. During the unfolding or folding of the electronic device, the second linkage part 42 can drive the first folding part 1 and the third folding part 3 to rotate at different angles relative to the second folding part 2, thereby realizing different unfolding postures of the electronic device to adapt to different usage scenarios.

[0044] It is understandable that when an electronic device has both a first linkage part 40 and a second linkage part 42, the first linkage part 40 or the second linkage part 42 can be selected to be used according to the actual usage situation, so that the electronic device has different unfolding states.

[0045] According to some embodiments of this application, such as Figure 7 and Figure 8 As shown, the unfolded state also includes a second state. In the second state, the first fold 1 and the second fold 2 are laid flat, and the third fold 3 has an angle with the second fold 2 and is located on the first side of the second fold 2, which is used to support the second fold 2 and the first fold 1.

[0046] In this embodiment, the unfolded state also includes a second state. In the second state, the third fold 3 is located on the first side of the second fold 2 and serves to support the second fold 2 and the first fold 1. At the same time, the first fold 1 and the second fold 2 are unfolded in a flat manner, and then displayed through the first fold 1 and the second fold 2, which increases the usage scenarios of the electronic device.

[0047] The third folding part 3 is located on the first side of the second folding part 2 and acts as a support. Thus, even without the support of the support, the electronic device can be put into a second state by the action of the second linkage part 42, making it convenient for the user to use.

[0048] According to some embodiments of this application, such as Figure 9 and Figure 10 As shown, the unfolded state also includes a third state. In the third state, the first folding part 1 is tilted relative to the second side of the second folding part 2, and the third folding part 3 is tilted relative to the first side of the second folding part 2 to support the second folding part 2 and the first folding part 1. The first folding part 1 is provided with a camera module.

[0049] In this embodiment, driven by the second linkage part 42, the electronic device can be in the third state of unfolded state. In the third state, the third folding part 3 and the first folding part 1 are respectively tilted relative to the first side and the second side of the second folding part 2, so that the third folding part 3 is used as a support on the second side of the second folding part 2 to support the first folding part 1 and the second folding part 2. At the same time, a camera module is provided on the first folding part 1, and the first folding part 1 is tilted relative to the second side of the second folding part 2, so that the first folding part 1 can face the object to be photographed, so as to facilitate the application of the photography scene.

[0050] like Figure 2 , Figure 4 , Figure 6 and Figure 13As shown, according to some embodiments of this application, the first linkage part 40 includes: a first gear 401, a second gear 402, a third gear 403, a fourth gear 404, and a first transmission member 405; the first gear 401 is disposed in the first folding part 1, the first transmission member 405, the second gear 402, and the third gear 403 are disposed in the second folding part 2, and the first transmission member 405 is movably connected to the second folding part 2, and the fourth gear 404 is disposed in the third folding part 3; wherein, during the process of the electronic device switching between the unfolded state and the folded state through the first linkage part 40, the first gear 401 is meshed with the second gear 402, the third gear 403 is meshed with the fourth gear 404, and the second gear 402 and the third gear 403 are connected through the first transmission member 405.

[0051] In this embodiment, the first linkage part 40 includes a gear linkage structure. Specifically, the first linkage part 40 includes a first gear 401 disposed in the first folding part 1, a first transmission member 405 disposed in the second folding part 2, a second gear 402 and a third gear 403 disposed in the second folding part 2, a transmission member that is connected to the second gear 402 and the third gear 403, and a fourth gear 404 disposed in the third folding part 3. In the process of switching an electronic device from a folded state to an unfolded state, taking the first folding part 1 driving the third folding part 3 via the first linkage part 40 as an example, when the first folding part 1 rotates relative to the second folding part 2, the first gear 401 meshes with the second gear 402, causing the transmission component to drive the third gear 403 to rotate. Then, through the meshing between the third gear 403 and the fourth gear 404, the third folding part 3 rotates relative to the second folding part 2 until it is in the unfolded state. Correspondingly, in the process of the electronic device moving from the unfolded state to the folded state, taking the first folding part 1 driving the third folding part 3 via the first linkage part 40 as an example, when the first folding part 1 rotates relative to the second folding part 2, the first gear 401 meshes with the second gear 402, causing the transmission component to drive the third gear 403 to rotate. Then, through the meshing between the third gear 403 and the fourth gear 404, the third folding part 3 rotates relative to the second folding part 2 until it is in the folded state. Through the meshing transmission between the gears, the rotation of the first folding part 1 and the third folding part 3 relative to the second folding part 2 is made smoother and more reliable.

[0052] It is understood that the rotation axes of the first gear 401, the second gear 402, the third gear 403, and the fourth gear 404 are in the same direction. The first transmission component 405 includes a transmission belt. Specifically, the diameters of the first gear 401, the second gear 402, the third gear 403, and the fourth gear 404 are the same.

[0053] In practical applications, the electronic device switches between an unfolded state and a folded state via the first linkage unit 40.

[0054] According to some embodiments of this application, the first gear 401 is movably connected to the first folding portion 1 so that the first gear 401 and the second gear 402 switch between engagement and disengagement.

[0055] In this embodiment, the first gear 401 is movably connected to the first folding part 1, allowing the first gear 401 to mesh with and disengage from the second gear 402. When the first gear 401 and the second gear 402 are meshed, the first linkage part 40 can link the first folding part 1 and the third folding part 3, causing them to rotate at the same angle relative to the second folding part 2, thus switching between different unfolded states. When the first gear 401 and the second gear 402 are disengaged, the first linkage part 40 cannot link the first folding part 1 and the third folding part 3, and users can manually switch to other unfolded states.

[0056] When the linkage mechanism 4 includes a second linkage part 42, and when the first gear 401 and the second gear 402 are separated, the linkage part 42 can be switched to link the first folding part 1 and the third folding part 3.

[0057] It is understandable that the fourth gear 404 can also be designed to be movably connected to the third folding part 3, so that the fourth gear 404 and the third gear 403 can switch between engagement and disengagement.

[0058] like Figure 2 , Figure 4 and Figure 6 As shown, according to some embodiments of this application, the first transmission member 405 is provided with a first mating part 406 and a first limiting part 407. The first mating part 406 is engaged with the second gear 402 and the third gear 403 for transmission, and the first limiting part 407 is used to restrict the rotation of the second gear 402 and the third gear 403 in the first state.

[0059] In this embodiment, the first transmission member 405 is provided with a first engaging portion 406 and a first limiting portion 407 at positions corresponding to the second gear 402 and the third gear 403, respectively. The first engaging portion 406 corresponding to the second gear 402 can mesh with the second gear 402 for transmission, and the first engaging portion 406 corresponding to the third gear 403 can mesh with the third gear 403 for transmission. This achieves power transmission, enabling the first folding portion 1 and the third folding portion 3 to move synchronously. Simultaneously, the first limiting portion 407 is used to restrict the rotation of the second gear 402 and the third gear 403 in the first state, thereby ensuring the stability of the electronic device in the first state.

[0060] In practical applications, the first mating part 406 includes teeth that mesh with the second gear 402 and the third gear 403. The first limiting part 407 includes stops that are disposed at both ends of the first mating part 406. Specifically, stops are provided at both ends of the first mating part 406 corresponding to the second gear 402, and stops are provided at both ends of the first mating part 406 corresponding to the third gear 403.

[0061] like Figure 8 , Figure 11 and Figure 14 As shown, according to some embodiments of this application, the second linkage part 42 includes: a fifth gear 421, a sixth gear 422, a seventh gear 423, an eighth gear 424, and a second transmission member 425; the fifth gear 421 is disposed in the first folding part 1, the second transmission member 425, the sixth gear 422, and the seventh gear 423 are disposed in the second folding part 2, and the second transmission member 425 is movably connected to the second folding part 2, and the eighth gear 424 is disposed in the third folding part 3; during the process of the electronic device switching between the unfolded state and the folded state through the second linkage part 42, the fifth gear 421 is meshed with the sixth gear 422, the seventh gear 423 is meshed with the eighth gear 424, and the sixth gear 422 and the seventh gear 423 are connected through the second transmission member 425, wherein the diameter of the seventh gear 423 and the eighth gear 424 is smaller than the diameter of the fifth gear 421 and the sixth gear 422.

[0062] In this embodiment, the second linkage 42 includes a fifth gear 421 disposed in the first folding part 1, a sixth gear 422 and a seventh gear 423 disposed in the second folding part 2, a second transmission member 425 connecting the sixth gear 422 and the seventh gear 423, and an eighth gear 424 disposed in the third folding part 3. During the process of switching the electronic device from an unfolded state to a folded state, taking manual opening as an example, the first folding part 1 rotates towards the second folding part 2. The fifth gear 421 drives the sixth gear 422 to rotate, the sixth gear 422 drives the seventh gear 423 to rotate via the second transmission member 425, and the seventh gear 423 drives the eighth gear 424 to rotate through meshing with it, thereby driving the third folding part 3 to rotate, thus switching the electronic device to the folded state. During the process of switching the electronic device from a folded state to an unfolded state, the first folding part 1 rotates away from the second folding part 2. The fifth gear 421 drives the sixth gear 422 to rotate, and the sixth gear 422 drives the seventh gear 423 to rotate via the second transmission member 425, which in turn drives the eighth gear 424 to rotate. This causes the third folding part 3, which is connected to the eighth gear 424, to rotate away from the second folding part 2 until it reaches the unfolded state. The diameters of the seventh gear 423 and the eighth gear 424 are smaller than the diameters of the fifth gear 421 and the sixth gear 422. Therefore, the angle of rotation of the first folding part 1 relative to the second folding part 2 is different from the angle of rotation of the third folding part 3 relative to the second folding part 2, thus achieving different unfolded postures.

[0063] In practical applications, the electronic device switches between the second unfolded state, the third state, and the folded state via the second linkage unit 42.

[0064] It is understandable that, such as Figure 14 As shown, the diameters of the seventh gear 423 and the eighth gear 424 are smaller than the diameters of the fifth gear 421 and the sixth gear 422, thereby changing the transmission ratio. This makes the angle of rotation of the third folding part 3 relative to the second folding part 2 smaller than the angle of rotation of the first folding part 1 relative to the second folding part 2, thus enabling the electronic device to be supported by the third folding part 3.

[0065] Furthermore, the rotation axes of the fifth gear 421, the sixth gear 422, the seventh gear 423, and the eighth gear 424 are in the same direction. The second transmission component 425 includes a transmission belt.

[0066] According to some embodiments of this application, the fifth gear 421 is movably connected to the first folding portion 1 so that the fifth gear 421 and the sixth gear 422 switch between engagement and disengagement.

[0067] In this embodiment, the fifth gear 421 is movably connected to the first folding part 1, so that the fifth gear 421 can mesh with or disengage from the sixth gear 422. Thus, when the fifth gear 421 meshes with the sixth gear 422, the second linkage part 42 can realize the linkage of the first folding part 1, the second folding part 2, and the third folding part 3. When the fifth gear 421 disengages from the sixth gear 422, the second linkage part 42 cannot realize the linkage of the first folding part 1 and the third folding part 3, and can be switched to other unfolded states by manual operation by the user.

[0068] When the linkage mechanism 4 includes a first linkage part 40 and a second linkage part 42, and when the fifth gear 421 and the sixth gear 422 are separated, the linkage can be switched to the first linkage part 40 to link the first folding part 1 and the third folding part 3.

[0069] It is understandable that the eighth gear 424 can also be designed to be movably connected to the third folding part 3 so that the eighth gear 424 and the seventh gear 423 can switch between engagement and disengagement.

[0070] In specific applications, when the linkage mechanism 4 includes a first linkage part 40 and a second linkage part 42, the linkage mode of the first linkage part 40 and the second linkage part 42 for the first folding part 1, the second folding part 2 and the third folding part 3 can be switched. Specifically, when the first folding part 1 and the third folding part 3 need to rotate by the same angle, the linkage is switched to the first linkage part 40 to link the first folding part 1 and the third folding part 3. Further, the fifth gear 421 is disengaged from the sixth gear 422, and the first gear 401 is engaged with the second gear 402. When the first folding part 1 and the third folding part 3 need to rotate by different angles, the linkage is switched to the second linkage part 42 to link the first folding part 1 and the third folding part 3. Further, the fifth gear 421 is engaged with the sixth gear 422, and the first gear 401 is disengaged from the second gear 402.

[0071] like Figure 10 and Figure 11 As shown, according to some embodiments of this application, the second transmission member 425 includes a second mating part 426 and a second limiting part 427. The second mating part 426 engages with the sixth gear 422 and the seventh gear 423 for transmission, and the second limiting part 427 is used to limit the rotation of the sixth gear 422 and the seventh gear 423 in the second state or the third state.

[0072] In this embodiment, the second transmission member 425 is provided with a second mating part 426 and a second limiting part 427 at positions corresponding to the sixth gear 422 and the seventh gear 423, respectively. The second mating part 426 corresponding to the sixth gear 422 can mesh with the sixth gear 422 for transmission, and the second mating part 426 corresponding to the seventh gear 423 can mesh with the seventh gear 423 for transmission, thereby realizing the transmission of power. At the same time, the second limiting part 427 is used to restrict the rotation of the sixth gear 422 and the seventh gear 423 in the second state or the third state, thereby ensuring the stability of the electronic device in the second state or the third state.

[0073] In practical applications, the second mating portion 426 includes teeth that mesh with the sixth gear 422 and the seventh gear 423. The second limiting portion 427 includes stops that are disposed at both ends of the second mating portion 426. Specifically, stops are provided at both ends of the second mating portion 426 corresponding to the sixth gear 422, and stops are provided at both ends of the second mating portion 426 corresponding to the seventh gear 423.

[0074] According to some embodiments of this application, when the linkage mechanism 4 includes a first linkage part 40 and a second linkage part 42, the first linkage part 40 includes: a first gear 401, a second gear 402, a third gear 403, a fourth gear 404, and a first transmission member 405; the first gear 401 is movably disposed within the first folding part 1, the second gear 402 and the third gear 403 are disposed within the second folding part 2, and the fourth gear 404 is disposed within the third folding part 3; the second linkage part 42 includes a sixth gear 422, a seventh gear 423, an eighth gear 424, and a second transmission member 425; the sixth gear 422 and the seventh gear 423 are ...4 are disposed within the first folding part 1, the second gear 402 and the third gear 403 are disposed within the second folding part 2, and the fourth gear 404 is disposed within the second folding part 3. Inside the second folding section 2, the eighth gear 424 is located inside the third folding section 3; the third gear 403 is meshed with the fourth gear 404, and the second gear 402 and the third gear 403 are connected through the first transmission member 405; the seventh gear 423 is meshed with the eighth gear 424, and the sixth gear 422 and the seventh gear 423 are connected through the second transmission member 425, wherein the diameter of the seventh gear 423 and the eighth gear 424 is smaller than the diameter of the first gear 401 and the sixth gear 422; the first gear 401 is movably connected to the first folding section 1 so that the first gear 401 meshes with the second gear 402 or with the sixth gear 422.

[0075] In this embodiment, when the linkage mechanism 4 includes both a first linkage part 40 and a second linkage part 42, the switching of the first linkage part 40 and the second linkage part 42 can be achieved by switching the first gear 401. Specifically, the first linkage part 40 includes a first gear 401 disposed in the first folding part 1, a second gear 402 and a third gear 403 disposed in the second folding part 2, a first transmission member 405 connected to the second gear 402 and the third gear 403, and a fourth gear 404 disposed in the third folding part 3. The second linkage part 42 includes a sixth gear 422 and a seventh gear 423 disposed in the second folding part 2, a second transmission member 425 connecting the sixth gear 422 and the seventh gear 423, and an eighth gear 424 disposed in the third folding part 3. The first gear 401 is movably connected to the first folding part 1, allowing it to mesh with the second gear 402 and the sixth gear 422 respectively. When the first gear 401 and the second gear 402 are engaged, as the first folding part 1 rotates relative to the second folding part 2, the second gear 402 drives the third gear 403 to rotate. The third gear 403 meshes with the fourth gear 404, thus rotating the third folding part 3. Consequently, the first folding part 1 and the third folding part 3 can rotate at the same angle relative to the second folding part 2. When the first gear 401 and the sixth gear 422 are engaged, the first folding part 1 rotates, causing the first gear 401 and the sixth gear 422 to mesh and drive the seventh gear 423 via the second transmission member 425. The meshing between the seventh gear 423 and the eighth gear 424 rotates the third folding part 3, allowing the first folding part 1 and the third folding part 3 to rotate at different angles relative to the second folding part 2. By movably configuring the first gear 401, the number of gears used is reduced, lowering the cost and weight of the electronic device.

[0076] In practical applications, the first gear 401 is slidably connected to the first folding part 1.

[0077] like Figure 4 As shown, according to some embodiments of this application, the electronic device further includes: a drive motor 5, connected to the linkage mechanism 4, for driving the linkage mechanism 4 to move so that the electronic device switches between an unfolded state and a folded state.

[0078] In this embodiment, the electronic device also includes a drive motor 5, which is connected to the linkage mechanism 4. The drive motor 5 can drive the linkage mechanism 4 to move, thereby causing the first folding part 1, the second folding part 2 and the third folding part 3 to move, so that the electronic device switches between an unfolded state and a folded state.

[0079] Furthermore, the drive motor 5 is connected to the third gear 403 and / or the seventh gear 423 of the linkage mechanism 4, and furthermore, the drive motor 5 is connected to the gear shaft of the third gear 403 and / or the gear shaft of the seventh gear 423 of the linkage mechanism 4.

[0080] According to some embodiments of this application, the electronic device further includes a control unit connected to the drive motor 5 for turning the drive motor 5 on or off.

[0081] In this embodiment, the electronic device further includes a control unit, which can control the electronic device to unfold or fold through electronic control or switch to manual mode to unfold or fold the electronic device.

[0082] It is understandable that when the control unit controls the drive motor 5 to drive the linkage mechanism 4 to move, the electronic device can be opened and closed automatically. When the control unit does not control the drive motor 5 to drive the linkage mechanism 4 to move, the electronic device can be opened and closed manually.

[0083] like Figure 12 As shown, according to some embodiments of this application, the electronic device further includes: a button 6 connected to a control unit, the control unit being used to receive pressing information of the button 6; when the linkage mechanism 4 includes a first linkage part 40 and a second linkage part 42: when the pressing information includes a first pressing, the control unit controls the drive motor 5 to drive the first linkage part 40 to move, and when the pressing information includes a second pressing, the control unit controls the drive motor 5 to drive the second linkage part 42 to move.

[0084] In this embodiment, the electronic device also includes a button 6, which is connected to a control unit. The control unit switches the linkage mode according to the pressing information of the button 6. Specifically, when the pressing information includes a first press, the control unit controls the drive motor 5 to drive the first linkage part 40 to move, so that the first folding part 1 and the third folding part 3 rotate at the same angle relative to the second folding part 2. When the pressing information includes a second press, the control unit controls the drive motor 5 to drive the second linkage part 42 to move, so that the first folding part 1 and the third folding part 3 rotate at different angles relative to the second folding part 2, thereby realizing multiple unfolding postures of the electronic device.

[0085] In practical applications, the press information includes a first press and a second press, which are specifically defined as the number of presses and / or the press duration. Further, the first press specifically includes one press or a first press duration, and the second press includes two presses or a second press duration. The first and second press durations can be set according to actual conditions.

[0086] According to some embodiments of this application, in the folded state, the first folded portion 1 and the third folded portion 3 are located on opposite sides of the second folded portion 2.

[0087] In this embodiment, in the folded state, the first fold 1 and the third fold 3 are located on both sides of the second fold 2, reducing the overall volume of the electronic device in the folded state.

[0088] In practical applications, the electronic device proposed in this application is a synchronous belt chain drive mechanism that can be started manually or electrically.

[0089] like Figure 12 As shown, the first folding section 1 houses a first gear 401, the second folding section 2 houses a second gear 402 and a third gear 403, and the third folding section 3 houses a fourth gear 404. The first gear 401 meshes with the second gear 402, and the third gear 403 meshes with the fourth gear 404. The second gear 402 and the third gear 403 are connected by a synchronous belt. The synchronous belt has teeth designed to drive the gears to rotate, causing the second gear 402 and the third gear 403 to rotate synchronously. When the electronic device is manually opened, the first folding section 1 is first opened. The first gear 401 rotates outward, causing the second gear 402 to rotate inward. Simultaneously, the synchronous belt is pulled, causing the third gear 403 to rotate outward, and the fourth gear 404, which meshes with the third gear 403, rotates inward, causing the third folding section 3 to open downward.

[0090] In electric mode, the motor inside the shaft of the third gear 403 drives the third gear 403 to rotate. When the third gear 403 rotates outward, the synchronous belt drives the second gear 402 to rotate inward. The first gear 401, which meshes with the second gear 402, rotates outward, applying a pulling force to the first folding part 1, causing the first folding part 1 to open outward. At the same time, the fourth gear 404, which meshes with the third gear 403, rotates inward, applying a downward pushing force to the third folding part 3, causing the third folding part 3 to open downward. The gears gradually rotate from the closed state to the open state. Figure 3 and Figure 4 It is in a half-open state.

[0091] like Figure 6 As shown, the timing belt is designed with teeth that drive the gear to rotate. The length of the teeth matches the rotation stroke. The timing belt has long teeth at both ends of the tooth stroke. When it rotates to the fully open or fully closed state, the gear is jammed by the long teeth and can no longer rotate, thus protecting the screen and the body. It will not pull on the screen or hit the body.

[0092] Furthermore, such as Figure 12As shown, this application designs two sets of gear structures. In the power-off state, the motor gear stops at the first synchronous shaft 7 for manual control. In the power-on state, control is achieved by pressing the button 6. Pressing the button 6 twice will jump to the second linkage part 42 for gear 2 control. The first folding part 1 houses the fifth gear 421, the second folding part 2 houses the sixth gear 422 and the seventh gear 423, and the third folding part 3 houses the eighth gear 424. The fifth gear 421 meshes with the sixth gear 422, and the seventh gear 423 meshes with the eighth gear 424. The sixth gear 422 and the seventh gear 423 are connected by a synchronous belt. The synchronous belt is designed with a locking mechanism to drive the gears to rotate, causing the sixth gear 422 and the seventh gear 423 to rotate synchronously. In electric mode, the motor inside the shaft of the seventh gear 423 drives the seventh gear 423 to rotate. When the seventh gear 423 rotates outward, the synchronous belt drives the sixth gear 422 to rotate inward. The fifth gear 421, which meshes with the sixth gear 422, rotates outward, providing a pulling force to the first folding part 1 and causing it to open outward. At the same time, the eighth gear 424, which meshes with the seventh gear 423, rotates inward, providing a downward pushing force to the third folding part 3 and causing it to open downward. The gears gradually rotate from the closed state to the open state. Figure 8 The principle behind the semi-open state is that the seventh gear 423 and the eighth gear 424 have smaller diameters than the fifth gear 421 and the sixth gear 422, so the rotation stroke is adjusted according to different proportions, thereby adjusting different gears.

[0093] To turn on all electronic devices, you can first close the electronic devices, then switch to level 1 to start, switching to the fully open mode. Level 1 is controlled by the first linkage unit 40.

[0094] Specifically, button 6 allows for electric opening and adjustment of different positions. The first folding section 1 is the main body of the phone, housing the screen and other components; button 6 is also located on this main body. The first linkage section 40 is responsible for the linkage opening of the Z-shaped tri-fold phone and contains a first gear 401, a second gear 402, a third gear 403, and a fourth gear 404. The first synchronous shaft 7 connects two sets of gears: the first gear 401, the second gear 402, the fifth gear 421, and the sixth gear 422. The second transmission component 425 (synchronous belt) provides synchronous rotation; within the second linkage section 42, it connects the sixth gear 422 and the seventh gear 423 for synchronous rotation. The first transmission component 405 (synchronous belt) also provides synchronous rotation; within the first linkage section 40, it connects the second gear 402 and the third gear 403 for synchronous rotation. The second folding section 2 is the middle body of the phone, housing a portion of the first linkage section 40 and a portion of the second linkage section 42, and housing other components, circuit boards, etc. Second Synchronous Shaft 8: The second synchronous shaft 8 connects two sets of gears, the third gear 403 and the fourth gear 404, the seventh gear 423 and the eighth gear 424, and has a built-in motor. Second Linkage Unit 42: Links the opening of the Z-shaped tri-fold phone, including the built-in fifth gear 421, sixth gear 422, seventh gear 423 and eighth gear 424. Third Folding Unit 3: The lower body of the phone, housing the screen and other components; the camera can be designed into this body.

[0095] It should be noted that this invention employs a synchronous belt chain transmission mechanism, allowing for the simplest and most elegant way to open a Z-shaped 3-fold phone, solving the user's intuition-insensitive pain point of opening it with both hands. In related technologies, it is difficult to open with both hands, resulting in a tight opening; this design makes it much easier to open. The electronic device proposed in this application can be opened and closed manually or electrically. In certain scenarios, such as with wet hands, there may be slippery conditions, making it difficult to open with sufficient force. This design, through a linkage mechanism, applies a force in one direction to the third fold section 3, making it easier to open. When the inner screen needs to be used and a stand is not available, it can support a large screen, allowing for use without a stand. Adjusting the angle is more convenient, and different settings can be designed. The angle adjustment effect is enhanced for photography scenarios, with two rotating axes and two degrees of freedom. The third fold section 3 can act as a stand and is fixed in place by the chain transmission mechanism. The built-in mechanism protects the screen, using a toothed travel to fix and limit the opening; once opened to a preset angle, it cannot be opened further, preventing damage to the screen. The built-in mechanism protects the device by using a toothed jaw to limit the movement of the gears, preventing further closure once a preset angle is reached, thus protecting the device from impact. The gear mechanism ensures a smooth, even opening process. In electric mode, different gear sets can be used to adjust the speed and angle dynamically, adapting to various scenarios.

[0096] The interconnected Z-shaped 3-fold screen phone solution provided by this invention can be applied not only to mobile phone products, but also to other electronic products with screen display functions, such as tablet computers and laptops.
