DETAILED DESCRIPTION

[0018] Certain embodiments of the present disclosure will be described with reference to the accompanying drawings. The descriptions are exemplary and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, numerous details are set forth in order to provide a thorough understanding of certain embodiments of the present disclosure. Embodiments may be implemented without the described details. Descriptions of certain well-known structures and techniques are omitted to avoid unnecessarily obscuring the concepts of the present disclosure.

[0019] The terms used herein are for the purpose of describing particular embodiments and are not intended to limit the present disclosure. The terms "having," "comprising," or the like, as used herein, indicate the presence of the features, steps, acts, and / or components, but do not preclude the presence or addition of one or more other features, steps, acts, or components.

[0020] Terms (including technical and scientific terms) used herein, unless otherwise defined, have the meanings commonly understood in the technical field. The terms used herein should be interpreted to have a meaning consistent with the context of the present disclosure and should not be interpreted in an idealized or overly rigid manner.

[0021] When using terms such as “at least one of A, B and C or the like”, the terms are interpreted according to the meaning of the term as generally understood in the technical field (for example, “a system comprising at least one of A, B and C” is intended to include, among other things, a system comprising only A; only B; only C; A and B; A and C; B and C; and / or A, B, C or the like).

[0022] Electronic devices such as laptop computers and foldable phones comprise a first body, a second body, and a connector. The connector may comprise two connectors. The first body and the second body are each connected by a connector component. The first body and the second body are unfolded and closed by relative rotation of the two connector components.

[0023] Due to the modeling parameters, the plane formed by the axes of the two connecting components may have an inclination angle relative to the first body, so that the plane is in a non-perpendicular state to the first body. When the electronic device is in a closed state, the free end of the first body and the free end of the second body are generally flush. The modeling parameters may cause the size of the first body and the size of the second body to be unequal in the first direction, which is perpendicular to the direction of rotation.

[0024] The relative rotation between the first body and the second body can be achieved by a synchronous transmission connection device. In a synchronous transmission connection device, the first body and the second body have the same deployment angle. For example, when the first body rotates 180 degrees in the forward direction, the second body rotates 180 degrees in the reverse direction, so that the electronic device unfolds 360 degrees. However, because the sizes of the first body and the second body are unequal, a step offset exists between the first body and the second body when the electronic device is in the unfolded state. The step offset is manifested in that the free end of the first body is not flush with the free end of the second body, and there is a certain distance between the two free ends in the first direction.The step offset affects the user experience.

[0025] The relative rotation between the first body and the second body can be achieved by an asynchronous transmission linkage. The asynchronous transmission linkage is used, and the linkage includes a first link component and a second link component. The process of unfolding the first body and the second body from the minimum angle to the maximum angle includes three phases. The first phase is to control only the rotation of the first link component, the second phase is to control only the rotation of the second link component, and the third phase is to control only the rotation of the first link component. However, the asynchronous transmission linkage may have the following features.

[0026] When the deployment angle of the first body and the second body reaches a predetermined switching angle, switching from the first phase to the second phase may occur, where the predetermined switching angle is, for example, 120 degrees. Taking a laptop computer as an example of the electronic device, the deployment angle of the first body and the second body during normal use is approximately between 100 degrees and 130 degrees, and this angle range is referred to as the normal use angle. Since the normal use angle is quite similar to the predetermined switching angle, switching may occur during the opening of the electronic device during normal use, and the switching may cause a feeling of frustration, affecting the opening sensation.

[0027] Certain electronic devices have touchscreens. In the asynchronous transmission connection device, one connection component may remain stationary at any stage, while the other connection component may rotate under the action of an external force, which is equivalent to using one connection component to support the display screen. The support force of the display screen is comparatively small. Therefore, the display screen may vibrate when the user operates the touchscreen, resulting in poor stability.

[0028] Certain embodiments of the present disclosure provide a connector and an electronic device having the connector. Compared to a synchronous transmission connector, the connector provided by certain embodiments of the present disclosure helps reduce or eliminate step offset, thereby improving the user experience. In certain embodiments, the connector helps reduce frustration experienced during normal use of the electronic device, thereby improving the feel of use. In certain embodiments, the connector helps support the first body and the second body at angles within the range of normal use, thereby improving stability.

[0029] The technical solution provided by the present disclosure will be described with reference to the accompanying drawings.

[0030] With reference to Fig. 1, the present disclosure provides, in certain embodiments, a connection device that can be applied to electronic devices such as laptop computers, mobile phones, or the like. The electronic device may include a first body 600 and a second body 700 that can be opened and closed. Taking a laptop computer as an example of the electronic device, one of the first body 600 and the second body 700 may be a display terminal having a display screen, and the other body may be a system terminal having a keyboard. The connection device may include a first connection component 100, a second connection component 200, and a setting component 300.

[0031] The first connecting component 100 is used to connect the first body 600. For example, the first connecting component 100 may include a first rotating shaft 110 and a first rotating shaft connecting portion 120. The first rotating shaft connecting portion 120 may be wound on and supported by the outer periphery of the first rotating shaft 110. The first rotating shaft connecting portion 120 may be fixedly connected to the first body 600 by a mechanical structure such as screws, so that the first body 600 and the first connecting component 100 rotate synchronously.

[0032] The second connecting component 200 is used to connect the second body 700. For example, the second connecting component 200 may include a second rotating shaft 210 and a second rotating shaft connecting portion 220. The second rotating shaft connecting portion 220 may be wound on and supported by the outer periphery of the second rotating shaft 210. The second rotating shaft connecting portion 220 may be fixedly connected to the second body 700 by a mechanical structure such as screws, so that the second body 700 and the second connecting component 200 rotate synchronously.

[0033] The adjustment component 300 is connected to the first connection component 100 and the second connection component 200 and is used to position the first connection component 100 with respect to the second connection component 200. The relative rotation of the first connection component 100 and the second connection component 200 includes two processes, namely the first rotation process and the second rotation process.

[0034] Taking a laptop computer as an example of the electronic device, the screen end and the system end of the laptop computer can be opened and closed between a minimum angle and a maximum angle, where the minimum angle can be 0 degrees and the maximum angle can be 360 ​​degrees. The first rotation process can represent a folding between the minimum angle and the predetermined angle, for example, the first rotation process represents a rotation from the Fig. 2A to the state shown in Fig. 2B. The second rotation process may represent a folding between a predetermined angle and a maximum angle, for example, the first rotation process represents a rotation from the state shown in Fig. 2B to the state shown in Fig. 2C. The predetermined angle may be 260 degrees or another angle; this is not limited in the present disclosure. The second rotation process may also represent a folding between the minimum angle and the first predetermined angle, and the first rotation process may represent a folding between the first predetermined angle and the maximum angle.

[0035] In the first rotation process, the first link component 100 and the second link component 200 rotate synchronously through the adjustment component 300. Synchronous rotation can be achieved through structures such as gears and timing belts, and the present disclosure does not limit the method for achieving synchronous rotation.

[0036] In the second rotation process, the adjustment component 300 is controlled to facilitate rotation of the first connecting component 100 or the second connecting component 200. That is, in the second rotation process, the adjustment component 300 disconnects the transmission between the first connecting component 100 and the second connecting component 200, so that one connecting component remains immobile and the other connecting component can rotate relative to a transmission assembly. In the second rotation process, the first connecting component 100 and the second connecting component 200 rotate asynchronously.

[0037] According to certain embodiments of the present disclosure, the adjustment component 300 may cause the first connection component 100 and the second connection component 200 to rotate synchronously in the first rotation process and to rotate asynchronously in the second rotation process, that is, the connection device utilizes a hybrid mode of synchronous and asynchronous rotation.

[0038] Since asynchronous transmission can be performed when the first body 600 and the second body 700 are unfolded from the minimum angle to the maximum angle, the rotation angle of the first connecting component 100 is unequal to the rotation angle of the second connecting component 200. The difference between the two rotation angles can be used to compensate for the step offset between the free end of the first body 600 and the free end of the second body 700, thereby improving the user experience.

[0039] In certain embodiments, synchronous transmission may be performed first, followed by asynchronous transmission. By setting the angle at which switching occurs between the first rotation process and the second rotation process, the predetermined switching angle is set within the angle range of abnormal use, so that the rotation process does not switch when the first body 600 and the second body 700 are unfolded to the angle of normal use. Therefore, during normal use, switching of the rotation shaft does not occur during the opening process, thereby reducing the sense of frustration and improving the usage experience.In addition, since synchronous transmission can be performed, the first transmission component and the second transmission component can be used to support the body during the synchronous transmission process, and the supporting force can be sufficiently large to avoid strong vibration when the user operates the display screen, thereby improving stability.

[0040] In certain embodiments, the connecting device may include a first connecting component 100, a second connecting component 200, and an adjustment component 300, wherein the adjustment component 300 may include a first coupling element 310, a second coupling element 320, and a control element 330.

[0041] The first coupling element 310 and the first connecting component 100 may be fixedly connected via a mechanical structure, and the first coupling element 310 and the first connecting component 100 may rotate synchronously.

[0042] The second coupling element 320 and the second connecting component 200 may be fixedly connected by a mechanical structure, and the second coupling element 320 and the second connecting component 200 may rotate synchronously. Additionally, the second coupling element 320 has a first connecting portion and a second connecting portion.

[0043] The control component 330 is used to limit the rotation of the first coupling element 310 during the second rotation process. The control element 330 and the first coupling element 310 may be connected to each other by a mechanical structure. For example, one of the control element 330 and the first coupling element 310 may have a groove, and the other of the two may have a protrusion, with the groove and protrusion engaging to achieve the limitation.

[0044] During the first rotation process, the first connecting portion of the second coupling member 320 is in transmission connection with the first coupling member 310, and the first coupling member 310 and the second coupling member 320 can rotate synchronously. The first coupling member 310 drives the first connecting component 100 to rotate, and the first connecting component 100 drives the first body 600 to rotate; the second coupling member 320 drives the second connecting component 200 to rotate, and the second connecting component 200 drives the second body 700 to rotate, so that the first body 600 and the second body 700 can rotate synchronously, and the opening and closing can be realized.

[0045] During the second rotation process, the second connecting portion of the second coupling element 320 disconnects the transmission between the first coupling element 310 and the second coupling element 320. Considering the second connecting component 200 as stationary, the second body 700 becomes or remains stationary. The first coupling element 310 drives the first connecting component 100 to rotate, and the first connecting component 100 drives the first body 600 to rotate, thereby realizing asynchronous rotation of the first body 600 and the second body 700.

[0046] In certain embodiments, the first coupling element 310 and the second coupling element 320 can realize a transmission connection and a transmission separation, and during the transmission separation process, the control element 330 is used to limit the rotation of the first coupling element 310 about its own axis to achieve locking of the first coupling element 310. The first connecting component 100 can be locked such that the first body 600 connected to the first connecting component 100 maintains an unchanged extension angle, so that the extension angle between the first body 600 and the second body 700 is a maximum angle upon completion of the second rotation process.

[0047] With a view to Fig. 3A to Fig. 3C, in certain embodiments, the connecting device may include a first connecting component 100, a second connecting component 200, and an adjustment component 300, wherein the adjustment component 300 may include a first coupling element 310, a second coupling element 320, and a control element 330.

[0048] The first coupling element 310 is a first gear. Accordingly, the first connecting component 100 may include a first rotating shaft 110. The first gear may be threaded onto and supported by the outer periphery of the first rotating shaft 110. The first gear and the first rotating shaft 110 may be an integral structural element or secured by a mechanical structure.

[0049] The second coupling element 320 is a second gear. Accordingly, the second connecting component 200 may include a second rotary shaft 210. The second gear may be threaded onto and supported by the outer periphery of the second rotary shaft 210. The second gear and the second rotary shaft 210 may be an integral structural member or may be fixedly held by a mechanical structure. In certain specific embodiments, the second gear is a half gear, the second gear has an annular sidewall, and a portion of the peripheral surface of the annular sidewall is provided with gears 321, and the gears 321 on the surface of the annular sidewall are the first connecting portion mentioned elsewhere herein.Another portion of the peripheral surface of the annular side wall is not provided with gears 321 to form an avoidance surface 322, and the avoidance surface 322 is the second connecting portion mentioned elsewhere herein.

[0050] In certain embodiments, the teeth of the first gear are transmission-connected to the teeth 321 of the second gear. If the rotation direction of the first gear and the second gear are the same, the first body 600 and the second body 700 rotate in the same direction, making normal opening and closing of the electronic device impossible.Therefore, in certain embodiments, the rotational directions of the first gear and the second gear are opposite, so that the meshing transmission of the first gear and the second gear drives the first rotary shaft 110 in the first connecting component 100 and the second rotary shaft 210 in the second connecting component 200 to rotate in opposite directions, and then drives the first body 600 and the second body 700 to approach or move away from each other through the first connecting component 100 and the second connecting component 200, thereby realizing the opening and closing of the electronic device.

[0051] In certain embodiments, the first coupling element 310 uses a first gear, and the second coupling element 320 uses a second gear with a half-tooth structure. The transmission connection between the first coupling element 310 and the second coupling element 320 is realized by the teeth 321 of the second gear, and the transmission separation between the first coupling element 310 and the second coupling element 320 is realized by the avoidance surface 322 of the second gear. The first coupling element 310 and the second coupling element 320 can together realize synchronous transmission with the desired transmission accuracy, and the switching angle between the first rotation process and the second rotation process can be controlled with increased precision.

[0052] In certain embodiments, the transmission connection between the first gear and the second gear can be achieved in various ways. In one example, during the first rotation process, the teeth 321 on the annular sidewall surface can directly mesh with the first gear for transmission. During the second rotation process, the avoidance surface 322 can avoid the teeth of the first gear, thereby separating the transmission between the first gear and the second gear. In another example, during the first rotation process, the teeth 321 on the annular sidewall surface can mesh with the first gear through a transmission assembly, and the transmission assembly can include a transmission gear 400. In the second rotation process, the avoidance surface 322 can avoid the teeth of the transmission gear 400, thereby separating the transmission between the first gear and the second gear.Compared to the direct meshing of the first gear and the second gear, in certain embodiments, the transfer gear 400 is arranged between the first gear and the second gear to increase the distance between the first connecting component 100 and the second connecting component 200, which provides more installation space for the control element 330 and thereby facilitates assembly. In certain embodiments where only a single transfer gear 400 is provided between the first gear and the second gear, the first gear and the second gear rotate in the same direction.Therefore, the number of transmission gears 400 may be an even number, for example, the number of transmission gears 400 is 2 or 4, to ensure that the first gear and the second gear rotate in opposite directions, thereby ensuring the normal opening and closing of the first body 600 and the second body 700.

[0053] It will be Fig. 4, Fig. 5, Fig. 7 and Fig. 8. In certain embodiments, the connecting device may include a first connecting component 100, a second connecting component 200, and an adjustment component 300, wherein the adjustment component 300 may include a first coupling element 310, a second coupling element 320, and a control element 330, and the control element 330 may include a first control element, a second control element, and a sliding element.

[0054] The first control element is connected to the first connecting component 100 and arranged coaxially with the first coupling element 310. For example, the first control element may utilize a wheel body, a gear, or the like in its structure, and the first control element and the first coupling element 310 may each be aligned coaxially with the first connecting component 100 to form the coaxial arrangement.

[0055] The second control element is connected to the second connecting component 200 and arranged coaxially with the second coupling element 320. For example, the first control element may utilize a wheel body, a gear, or the like in its structure, and the second control element and the second coupling element 320 may be aligned coaxially with the first connecting component 100 to form the coaxial arrangement.

[0056] The sliding element is arranged between the first control element and the second control element and is used to switch between the first connecting component 100 and the second connecting component 200, such that the first connecting component 100 or the second connecting component 200 provides rotation during the second rotation process. For example, the sliding element can lock one of the first control element and the second control element by sliding in a predetermined direction and allow the other element to continue rotating freely, where the predetermined direction can be a direction parallel to the rotation axis of the first connecting component 100 or another direction.

[0057] In certain embodiments, the control element 330 comprises a first control element, a second control element and a sliding element, the first control element and the second control element are arranged coaxially with the first connecting component 100 and the second connecting component 200, respectively, and the switching of the rotation process is achieved by controlling the sliding element.

[0058] In certain embodiments, a mounting bracket 500 may be used to support the assembly of various components and elements. For example, the mounting bracket 500 may include a first bracket 510, a second bracket 520, a third bracket 530, and a fourth bracket 540. The present disclosure is not limited to any specific structure of the mounting bracket 500.

[0059] For example, some of the mounting brackets 500 may be simultaneously fitted onto the outer peripheries of the first rotary shaft 110 in the first connecting component 100 and the second rotary shaft 210 in the second connecting component 200. The mounting bracket 500 is mainly used to support and restrict various components. For example, the transmission gear 400 may be arranged between the second bracket 520 and the third bracket 530 so that the second bracket 520 and the third bracket 530 can engage the end surface of the transmission gear 400, thereby restricting the axial position of the transmission gear 400.The first control element, the second control element, and the sliding element may be arranged between the third bracket 530 and the fourth bracket 540, such that the third bracket 530 and the fourth bracket 540 may axially confine the first control element and the second control element and may confine the sliding direction of the sliding element.

[0060] It will be Fig. 4, Fig. 5, Fig. 7 and Fig. 8. In certain embodiments, the first control element is a first gear body 331, and the first gear body 331 is arranged coaxially with the first coupling element 310. For example, the first connection component 100 includes a first rotating shaft 110, and the first coupling element 310 may be a first gear that is threaded onto the outer periphery of the first rotating shaft 110, or the first coupling element 310 may also take on other structures. The first gear body 331 may be threaded onto the outer periphery of the first rotating shaft 110.

[0061] In certain embodiments, the second control element is a second gear body 332, and the second gear body 332 is arranged coaxially with the second coupling element 320. For example, the second connection component 200 includes a second rotating shaft, and the second coupling element 320 may be a second gear threaded onto the outer periphery of the second rotating shaft, or the second coupling element 320 may also take on other structures. The second gear body 332 may be threaded onto the outer periphery of the second gear rotating shaft.

[0062] In certain embodiments, the sliding member is a slider 333, and the slider 333 has a first end and a second end.

[0063] During the first rotation process, and in certain embodiments, the first end of the slider 333 slides with the first gear body 331 and the second end of the slider 333 slides with the second gear body 332 without restricting the transmission between the first coupling element 310 and the second coupling element 320.

[0064] During the second rotation process, and in certain embodiments, the first end of the slider 333 is connected to the first gear body 331 at a limited position. The limited position connection can be an abutment, for example, the first end of the slider 333 abuts the surface of the first gear body 331 and remains relatively unmoved or stationary. The limited position connection can also be a sliding connection, for example, the slider 333 can slide relative to the first gear body 331 in one direction (for example, the axial direction of the first gear body 331) but remains unmoved or stationary relative to the first gear body 331 in another direction (for example, the circumferential direction of the first gear body 331). The rotation of the first gear body 331 is limited by the limited position connection. The second end of the slider 333 is slidably engaged with the second gear body 332.

[0065] In certain embodiments, a mounting bracket 500 may be used to support the assembly of various components and elements. For example, the mounting bracket 500 may include a first bracket 510, a second bracket 520, a third bracket 530, and a fourth bracket 540. The present disclosure may utilize any suitable mounting bracket 500 structure.

[0066] For example, some of the mounting brackets 500 may be simultaneously fitted onto the outer peripheries of the first rotary shaft 110 in the first connecting component 100 and the second rotary shaft 210 of the second connecting component 200. The mounting bracket 500 is mainly used to support various components and limit their position. For example, the transmission gear 400 may be arranged between the second bracket 520 and the third bracket 530 so that the second bracket 520 and the third bracket 530 can engage the end surface of the transmission gear 400, thereby limiting the axial position of the transmission gear 400.The first control element, the second control element, and the sliding element may be arranged between the third bracket 530 and the fourth bracket 540, such that the third bracket 530 and the fourth bracket 540 may axially limit the first control element and the second control element and may also limit the sliding direction of the sliding element.

[0067] In certain embodiments, each of the first control element and the second control element adopts a wheel body structure, wherein synchronous rotation, asynchronous rotation, and switching of the rotation process are achieved by the rotation of the wheel body and the cooperation with the slider 333.

[0068] The connecting device according to certain embodiments is described herein in connection with Fig. 4 to Fig. 7C described.

[0069] The connection device according to certain embodiments comprises a first connection component 100, a second connection component 200, and an adjustment component 300. The adjustment component 300 may comprise a first coupling element 310, a second coupling element 320, and a control element 330. The control element 330 may comprise a first control element, a second control component, and a sliding element. Descriptions of the structures of these components can be found elsewhere herein and are not repeated for the sake of brevity. In certain embodiments, the first control element is the first wheel body 331, the second control element is the second wheel body 332, and the sliding element is the slider 333. The first wheel body 331, the second wheel body 332, and the slider 333 are described herein in connection with Fig. 4 and Fig. 5 described.

[0070] In certain embodiments, the first wheel body 331 is a concave wheel. The sidewall of the outer periphery of the first wheel body 331 has an arcuate curved surface 3311 and a concave surface 3312. The concave surface 3312 is concave relative to the arcuate curved surface 3311.

[0071] In certain embodiments, the second gear body 332 is a cam, the sidewall of the outer circumference of the second gear body 332 has a first arcuate surface 3321 and a second arcuate surface 3322, and the radius of the first arcuate surface 3321 is smaller than the radius of the second arcuate surface 3322. The sidewall of the outer circumference of the second gear body 332 can have a transition surface located between the first arcuate surface 3321 and the second arcuate surface 3322 to create a smooth transition between the different radii of the first arcuate surface 3321 and the second arcuate surface 3322.

[0072] In certain embodiments, the first end of the slider 333 adopts a convex arc structure to facilitate engagement with the concave surface 3312 of the first wheel body 331, and the second end of the slider 333 may adopt a flat surface or curved surface structure.

[0073] In certain embodiments, the first body 600 and the second body 700 of the electronic device can be opened and closed between a minimum angle and a maximum angle, the minimum angle can be 0 degrees and the maximum angle can be 360 ​​degrees, wherein the first rotation process can represent the rotation between the minimum angle and the predetermined angle and the second rotation process can represent the rotation between the predetermined angle and the maximum angle. With regard to Fig. 4 to Fig. In Figure 6C, the unfolding process of the electronic device is described, assuming a predetermined angle of 260 degrees as an example. The predetermined angle may also be any suitable angle other than 260 degrees.

[0074] It will be Fig. 4, Fig. 5 and Fig. 6A. During the process of unfolding the electronic device from 0 degrees to 260 degrees (e.g., the first rotation process), the transmission between the first coupling member 310 and the second coupling member 320 occurs synchronously. A description of the method of synchronous transmission is provided elsewhere herein. The transmission is performed, for example, by the meshing of the teeth of the first gear and the teeth of the second gear. The first gear and the second gear each rotate 130 degrees, thereby driving the first connecting component 100 and the second connecting component 200 to each rotate 130 degrees, so that the first body 600 and the second body 700 are unfolded 260 degrees.In certain embodiments, the first end of the slider 333 is slidably engaged with the arcuate curved surface 3311 of the concave wheel of the first wheel body 331 and the second end of the slider 333 is slidably engaged with the first arcuate surface 3321 of the second wheel body 332, and the slider 333 does not exert any restraining effect on the first wheel body 331 and the second wheel body 332.

[0075] It will be Fig. 4, Fig. 5 and Fig. 6B. When the electronic device is unfolded to 260 degrees, a transmission disconnection occurs between the first coupling member 310 and the second coupling member 320. A description of the transmission disconnection method is found elsewhere herein. For example, when the second gear rotates, the avoidance surface 322 on the second gear rotates to the meshing position of the second gear and other components (such as the transmission gear 400), and the teeth of the second gear disengage from the transmission gear 400, thus disconnecting the transmission between the first gear and the second gear.In certain embodiments, the second end of the slider 333 slides to the end portion of the first arcuate surface 3321 of the second gear body 332, and the transition surface or the initial portion of the first arcuate surface 3321 pushes the slider 333 to move toward the first gear body 331 until the first end of the slider 333 engages the concave surface 3312 of the first gear body 331, thereby limiting the rotation of the first rotary shaft 110, but allowing the second end of the slider 333 to continue sliding around the second arcuate surface 3322 of the second gear body 332, and switching from the first rotation process to the second rotation process.

[0076] It will be Fig. 4, Fig. 5 and Fig. 6C. During the process of unfolding the electronic device from 260 degrees to 360 degrees (e.g., the second rotation process), the separation of the transmission between the first coupling member 310 and the second coupling member 320 is maintained. For example, the avoidance surface 322 on the second gear is separated from the teeth of other components, so that the rotation of other components cannot be transmitted to the second coupling member. In certain embodiments, the first end of the slider 333 abuts against the concave surface 3312 of the first gear body 331 to limit the rotation of the first gear body 331, thereby limiting the rotation of the first connecting component 100. In certain embodiments, the second arc surface 3322 of the second gear body 332 abuts against and slides with the second end of the slider 333.In the second rotation process, the slider 333, the first wheel body 331 and the first link component 100 remain relatively unmoved or stationary, while the second link component 200 rotates about its own axis, and the second link component 200 can further rotate by 100 degrees.

[0077] Certain features of the electronic device's deployment process from 0 degrees to 360 degrees have been described. The electronic device's closing process from 360 degrees to 0 degrees can be the opposite of, or a reversal of, the deployment process, and the description of the closing process will not be repeated for brevity.

[0078] In certain embodiments, the synchronous transmission and the asynchronous transmission of the first link component 100 and the second link component 200 are realized, and the switching between the synchronous transmission and the asynchronous transmission is realized by the cooperation of the concave wheel, the convex wheel or cam, and the slider 333.

[0079] Through the above deployment process, and in certain embodiments, the first body 600 rotates 130 degrees under the drive of the first connecting component 100, and the second body 700 rotates 230 degrees under the drive of the second connecting component 200. The rotation angles of the first body 600 and the second body 700 are not equal. The angle difference is used to compensate for the step offset between the free end of the first body 600 and the free end of the second body 700, thereby improving the user experience.

[0080] In certain embodiments, the deployment process first performs synchronous transmission and then asynchronous transmission, and the switching angle between synchronous transmission and asynchronous transmission is 260 degrees. Taking a laptop computer as an example of the electronic device, the deployment angle of the electronic device normally used by the user is approximately between 100 degrees and 130 degrees. Therefore, when the first body 600 and the second body 700 are deployed to the normal use angle, no switching between synchronous transmission and asynchronous transmission occurs, thereby reducing the sense of frustration and improving the usage experience. Furthermore, the process of deploying the first body 600 and the second body 700 to the normal use angle is a synchronous transmission process.During the synchronous transmission process, the first transmission assembly and the second transmission assembly can be used to simultaneously support the first body 600, and the supporting force is comparatively large. When the user operates the first body 600, strong vibration is reduced or eliminated, thereby improving stability.

[0081] The connecting device according to certain embodiments is designed with a view to Fig. 7 to Fig. 9C described.

[0082] In certain embodiments, the connection device comprises a first connection component 100, a second connection component 200, and an adjustment component 300. The adjustment component 300 may comprise a first coupling element 310, a second coupling element 320, and a control element 330. The control element 330 may comprise a first control element, a second control element, and a sliding element. A structural description of these components can be found elsewhere herein and is not repeated for brevity. In certain specific embodiments, the first control element is a first wheel body 331, the second control element is a second wheel body 332, and the sliding element is a slider 333. A description of the first wheel body 331, the second wheel body 332, and the slider 333 can be found in connection with Fig. 7 and Fig. 8.

[0083] In certain embodiments, the outer wall of the first wheel body 331 is formed with a first limiting structure 3313 and a second limiting structure 3314. The first limiting structure 3313 is strip-shaped and extends along the circumference of the first wheel body 331. The second limiting structure 3314 is strip-shaped and extends in the axial direction of the first wheel body 331. In certain specific embodiments, respective ends of the first limiting structure 3313 and the second limiting structure 3314 are connected to form an L-shaped structure.

[0084] In certain embodiments, the outer sidewall of the second wheel body 332 is formed with a third limiting structure 3323 and a fourth limiting structure 3324. The third limiting structure 3323 is strip-shaped and extends along the circumference of the second wheel body 332, and the third limiting structure 3323 corresponds to the position of the first limiting structure 3313. The fourth limiting structure 3324 is spiral-shaped, and the respective ends of the third limiting structure 3323 and the fourth limiting structure 3324 are connected.

[0085] The end of the slider 333 may be provided with a structure that matches the first wheel body 331 and the second wheel body 332. In certain embodiments where each of the first limiting structure 3313, the second limiting structure 3314, the third limiting structure 3323, and the fourth limiting structure 3324 is a groove structure, a protrusion structure may be provided at the end of the slider 333. In certain embodiments where all four of the above limiting structures are protrusion structures, a groove structure may be provided at the end of the slider 333.

[0086] In certain embodiments and further with regard to Fig. 7 to Fig. 9C, the unfolding process of the electronic device is described by assuming the first rotation process as a rotation between 0 degrees and 260 degrees and the second rotation process as a rotation between 260 degrees and 360 degrees as an example.

[0087] It will be Fig. 7, Fig. 8 and Fig. 9A. During the process of unfolding the electronic device from 0 degrees to 260 degrees (e.g., the first rotation process), the transmission between the first coupling member 310 and the second coupling member 320 occurs synchronously. A description of the method of synchronous transmission is provided elsewhere herein. Transmission is performed, for example, by the meshing of the teeth of the first gear and the teeth of the second gear. The first gear and the second gear each rotate 130 degrees, thereby driving the first connecting component 100 and the second connecting component 200 to each rotate 130 degrees, so that the first body 600 and the second body 700 are unfolded 260 degrees.In certain specific embodiments, the first end of the slider 333 is slidably engaged with the first limiting structure 3313 of the first gear body 331, and the second end of the slider 333 is slidably engaged with the third limiting structure 3323 of the second gear body 332. In certain embodiments where the slider 333 is considered a stationary part, the first gear body 331 and the second gear body 332 each rotate about their own axis, and the slider 333 does not affect the synchronous transmission between the first connecting component 100 and the second connecting component 200, so that the first connecting component 100 and the second connecting component 200 rotate synchronously.

[0088] It will be Fig. 7, Fig. 8 and Fig. 9B. In certain embodiments, transmission separation occurs between the first coupling member 310 and the second coupling member 320 when the electronic device is unfolded to 260 degrees. A description of the transmission separation method is provided elsewhere herein. For example, as the second gear rotates, the avoidance surface 322 on the second gear rotates to the meshing position of the second gear and other components (such as the transmission gear 400). Then, the first end of the slider 333 slides to the connecting portion of the first limiting structure 3313 and the second limiting structure 3314, the second end of the slider 333 slides to the connecting portion of the third limiting structure 3323 and the fourth limiting structure 3324, and the first rotation process switches to the second rotation process.

[0089] It will be Fig. 7, Fig. 8 and Fig. 9C. During the process of unfolding the electronic device from 260 degrees to 360 degrees (e.g., the second rotation process), the separation of the transmission between the first coupling element 310 and the second coupling element 320 is maintained. For example, the avoidance surface 322 on the second gear is separated from the gear teeth of other components (such as the transmission gear 400), so that the rotation of other components is not transmitted to the second coupling. In certain embodiments, the first end of the slider 333 slides with the second limiting structure 3314 of the first gear body 331, and the second end of the slider 333 slides with the fourth limiting structure 3324 of the second gear body 332.The fourth limiting structure 3324 exerts a force on the second end of the slider 333, causing the slider 333 to slide in a direction parallel to the axis of the first gear body 331. As the slider 333 slides, the first end of the slider 333 cooperates with the second limiting structure 3314 and limits rotation of the first gear body 331 about its own axis. During the second rotation process, the first gear body 331 and the first connecting component 100 remain relatively unmoved or stationary. Considering the first gear body 331 and the first connecting component 100 as stationary, the second connecting component 200 rotates about its own axis, allowing the second connecting component 200 to rotate a further 100 degrees, and the slider 333 slides in a direction parallel to the axis of the first gear body 331.

[0090] Certain features of the electronic device's deployment process from 0 degrees to 360 degrees have been described. The electronic device's closing process from 360 degrees to 0 degrees can be the opposite of, or a reversal of, the deployment process, and the description of the closing process will not be repeated for brevity.

[0091] In certain embodiments, the synchronous transmission and the asynchronous transmission of the first connection component 100 and the second connection component 200 are realized, and the switching between the synchronous transmission and the asynchronous transmission is realized by the cooperation of the groove-wheel structure and the slider 333.

[0092] Through the above deployment process, and in certain embodiments, the first body 600 rotates 130 degrees under the drive of the first connecting component 100, and the second body 700 rotates 230 degrees under the drive of the second connecting component 200. The rotation angles of the first body 600 and the second body 700 are not equal. The angle difference is used to compensate for the step offset between the free end of the first body 600 and the free end of the second body 700, thereby improving the user experience.

[0093] In certain embodiments, the deployment process first performs synchronous transmission and then asynchronous transmission, and the switching angle between synchronous transmission and asynchronous transmission is approximately 260 degrees. Taking a laptop computer as an example of the electronic device, the deployment angle of the electronic device normally used by the user is approximately between 100 degrees and 130 degrees. Therefore, when the first body 600 and the second body 700 are deployed to the normal use angle, no switching between synchronous transmission and asynchronous transmission occurs, thereby reducing the sense of frustration and improving the usage experience. The process of deploying the first body 600 and the second body 700 to the normal use angle is a synchronous transmission process.During the synchronous transmission process, the first transmission assembly and the second transmission assembly can be used to simultaneously support the first body 600, and the supporting force is comparatively large. When the user operates the first body 600, strong vibration is reduced or eliminated, thereby improving stability.

[0094] The present disclosure also provides an electronic device, which may be a laptop computer, a foldable mobile phone, or the like. The electronic device may include a first body 600 and a second body 700 that can be opened and closed. Taking a laptop computer as an example of the electronic device, one of the first body 600 and the second body 700 may be a display terminal having a display screen, and the other body may be a system terminal having a keyboard. The electronic device also includes a connector, which may be any of the connectors described elsewhere herein.

[0095] In certain embodiments, the connecting device comprises a first connecting component 100, a second connecting component 200, and an adjustment component 300, wherein the first connecting component 100 is connected to the first body 600, the second connecting component 200 is connected to the second body 700, and the adjustment component 300 is connected to the first connecting component 100 and the second connecting component 200. The adjustment component 300 is used to facilitate rotation between the first connecting component 100 and the second connecting component 200. When the first body 600 is in a first rotation mode relative to the second body 700, during the first rotation process of the connecting device, the first connecting component 100 and the second connecting component 200 rotate synchronously through the adjustment component 300.When the first body 600 is in a second rotation mode relative to the second body 700, during the second rotation process, the connection device is controlled by the adjustment component 300 to allow rotation of the first connection component 100 or the second connection component 200.

[0096] The electronic device provided according to certain embodiments contributes to mitigating the problem of step misalignment, thereby improving the user experience. Furthermore, the frustration associated with opening the electronic device during normal use can be alleviated, the feel of use can be improved, and the stability of the first body 600 and the second body 700 can be improved.

[0097] In certain embodiments, the first body 600 and the second body 700 are rectangular, and the direction perpendicular to the rotational direction of the first connecting component 100 is referred to as the first direction. The size of the first body 600 in the first direction is smaller than the size of the second body 700 in the first direction, and the first direction is perpendicular to the rotational direction of the first connecting component 100.

[0098] Of the two opposite ends of the first body 600, one end is connected to the first connecting component 100 in the connecting device, and this end is referred to as the connecting end; the other end is not connected to the first connecting component 100, and this end is referred to as the free end. Similarly, of the two opposite ends of the second body 700, one end is connected to the second connecting component 200 in the connecting device, and this end is referred to as the connecting end; the other end is referred to as the free end.

[0099] In certain embodiments and with regard to Fig. 10A, the first body 600 is in a first position relative to the second body 700, and the free end of the first body 600 is flush with the free end of the second body 700. The first position may be a relative position of the electronic device in a closed state. For example, the first position may be when the deployment angle between the first body 600 and the second body 700 is 0 degrees.

[0100] In certain embodiments and with regard to Fig. 10B, the first body 600 is in a second position relative to the second body 700, the free end of the first body 600 is flush with the free end of the second body 700, and the second position may be the relative position of the electronic device in the deployed state. For example, the second position may be such that the deployment angle between the first body 600 and the second body 700 is 360 degrees.

[0101] In certain embodiments, the connecting device comprises a first connecting component 100 and a second connecting component 200. The first connecting component 100 may include a first rotary shaft 110 and a first rotary shaft connecting portion 120. The first rotary shaft connecting portion 120 may be fixedly connected to the first body 600 by a mechanical structure such as a screw. The second connecting component 200 may include a second rotary shaft 210 and a second rotary shaft connecting portion 220. The second rotary shaft connecting portion 220 may be fixedly connected to the second body 700 by a mechanical structure such as screws.

[0102] The end of the first rotary shaft connecting portion 120 remote from the first rotary shaft 110 is referred to as the first end, the end of the second rotary shaft connecting portion 220 remote from the second rotary shaft 210 is referred to as the second end, and the distance between the first end and the second end in the first direction is referred to as the connecting portion step offset. In certain embodiments, when the first body 600 is at the first position and the second position relative to the second body 700, the connecting portion step offset between the first rotary shaft connecting portion 120 and the second rotary shaft connecting portion 220 is the same. For example, in the first position, the connecting portion step offset is 1 cm (centimeter), and in the second position, the connecting portion step offset is also 1 cm.By adjusting the connecting portion step offset of the first rotary shaft connecting portion 120 and the second rotary shaft connecting portion 220 in two positions (for example, the first position and the second position), it is ensured that the first body 600 and the second body 700 are flush with each other in the two positions.

[0103] In certain embodiments, the first body 600 has a display surface for display and a first surface facing away from the display surface, and the second body 700 has an input surface for input and a second surface facing away from the input surface. The direction parallel to the direction of rotation of the first connecting component 100 is referred to as the second direction.

[0105] In the second position, the first surface and the second surface are arranged opposite each other, and when projected in the second direction, a line formed by the connecting end of the first body 600 and the connecting end of the second body 700 has a second tilt angle relative to the first body 600. In certain specific embodiments, the first tilt angle is equal to the second tilt angle.

[0106] In certain embodiments, the first tilt angle is equal to the second tilt angle such that when the first body 600 is in the first position and in the second position relative to the second body 700, the free end of the first body 600 is flush with the free end of the second body 700, thereby enhancing the user experience.
