Detailed Implementation

[0050] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0051] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0052] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows:

[0053] Example 1

[0054] Reference Appendix Figure 1 Appendix Figure 2 and attached Figure 3 The connecting device provided in this application embodiment includes a torque assembly 1, two rotating arms 2, and a protective member 3. The two rotating arms 2 are movably connected to the torque assembly 1, and the two rotating arms 2 move relative to each other under the action of the torque assembly 1. The protective member 3 at least covers the target side of the two rotating arms 2, and the protective member 3 deforms with the relative movement of the two rotating arms 2. The protective member 3 is used to protect electronic components 4 located on the target side of the electronic device when the connecting device is installed on the electronic device. Figure 2 The rotating arm 2 of the shaft (i.e., the connecting device) shown is covered by the protective member 3. Figure 2 The part of the rotating arm 2 of the rotating shaft that connects to the body of the electronic device is not shown.

[0055] Understandably, in order to address the technical problem of black spots (GDS) caused by the contact device supporting the switching between unfolded and folded postures of flexible screens in existing foldable electronic devices due to contact or compression of the flexible screen, especially with reference to the attached... Figure 5 As shown, during the bending process of the flexible screen corresponding to electronic component 4, the rotating arm 2 needs to contact or squeeze the flexible screen in order to constrain its bending to form the target shape or state. During this process, it is very easy to cause sharp point contact and abnormal squeezing of the flexible screen. In this embodiment, the protective component 3 covers the target side of the rotating arm 2, that is, the side facing the electronic component 4, thereby forming a protective layer between the rotating arm 2 and the electronic component 4, i.e., the flexible screen. This prevents the rotating arm 2 from causing black spots (GDS) or even screen damage due to contact or squeezing of the electronic component 4, i.e., the flexible screen. It effectively protects the electronic component 3, i.e., the flexible display screen, and improves the stability and safety of the connection device.

[0056] The connecting device provided in this embodiment can be applied to, but is not limited to, foldable electronic devices, such as foldable mobile phones, laptops, etc. The torque component 1 of the connecting device is used to generate, transmit, and control rotational motion and torque. The rotating arm 2 is used to connect the relatively rotating electronic device body and rotate relative to the torque component 1 to achieve folding. It is easy to understand that the aforementioned electronic component 4 can be a deformable display screen located on the target side of the connecting device on the electronic device. The display screen covers the connecting device, and thus, when the two rotating arms 2 of the connecting device move relative to each other, it can drive the display screen to deform, i.e., fold or flatten. Folding can include both forward folding and reverse folding, meaning that the two parts of the electronic device capable of relative folding can flip and fold between 0 degrees and 360 degrees. In foldable electronic devices, the number of connecting devices can be designed and adjusted according to actual needs, for example: one in the middle of the folding axis, one at each end of the folding axis, or multiple at intervals along the folding axis, etc.

[0057] Among them, reference appendix Figure 2 and attached Figure 3 In this embodiment, the torque component 1 can be a torque component comprising two parallel rotating shafts, i.e., a dual-shaft form. The rotating shafts are fitted with relevant springs or other structures to achieve the relevant torque requirements. This structure is easily understood by those skilled in the art and will not be elaborated upon here. The following description of this embodiment will focus on the first rotating shaft 11 and the second rotating shaft 13. In one embodiment of this application, the torque component 1 can be… Figure 2 The form shown is that of an external bushing; another embodiment of this application is as follows: Figure 3 The connecting device shown may include a base 5, the torque assembly 1 is fixed inside the base 5, and the two rotating arms 2 are located outside the base 5. The base 5 is a rigid structure, which provides a stable mounting carrier for the torque assembly 1, so that the first rotating shaft 11 and the second rotating shaft 13 can form an integral structure of the torque assembly 1. At the same time, in order to shield the internal structure of the torque assembly 1 and prevent the electronic components 4 from contacting or rubbing against the internal structure of the torque assembly 1 when installed in electronic devices, a cover 12 can be provided on the target side of the base 5 in this embodiment. An opening can be provided on the cover 12 corresponding to the rotating arm 2, so that the rotating arm 2 can be exposed through the opening and ensure that the rotating arm 2 will not be interfered with by the cover 12 when moving relative to the torque assembly 1. At the same time, the setting of the cover 12 can effectively reduce the overall thickness of the torque assembly 1 compared with the bushing, which is helpful for application in ultra-thin devices.

[0058] The two rotating arms 2 are respectively rotatably connected to the first rotating shaft 11 and the second rotating shaft 13. The two rotating arms 2 can be linked together through the action of the two rotating shafts. For example, see attached figure. Figure 4The first rotating shaft 11 and the second rotating shaft 13 can rotate in conjunction with each other through gear meshing. That is, the rotation of the first rotating shaft 11 can drive the rotation of the second rotating shaft 13, and the rotation of the second rotating shaft 13 can also drive the rotation of the first rotating shaft 11. When the first rotating shaft 11 and the second rotating shaft 13 rotate relative to each other, they can drive the two rotating arms 2 to move relative to each other, either closer or farther apart. It is easy to understand that the two rotating arms 2 have at least a first relative position relationship and a second relative position relationship. Under the first relative position relationship, the two rotating arms 2 and the torque component 1 satisfy the parallel condition, and the two rotating arms 2 also satisfy the parallel condition, i.e., the flattened state. Under the second relative position relationship, the two rotating arms 2 and the torque component 1 satisfy the perpendicular condition, and the two rotating arms 2 satisfy the parallel condition, i.e., the folded state. Here, satisfying the parallel condition can be parallel or approximately parallel, and satisfying the perpendicular condition is similar. The rotating arms 2 can rotate around the rotating shaft through gear meshing with the rotating shaft, or they can be sleeved on the rotating shaft and rotate with the rotation of the rotating shaft. In this embodiment, when the connecting device is installed in the electronic device, the two rotating arms 2 can be used to connect two relatively foldable bodies of the electronic device, thereby realizing the relative rotation and relative folding of the two bodies. The two rotating arms 2 can be as follows: Figure 3 The torsion assembly 1 is arranged symmetrically relative to it, or it can be staggered along the axial direction of the torsion assembly 1.

[0059] The protective component 3 is a deformable structure, which can be a plate-like structure, a sheet-like structure, etc. The protective component 3 can be made of a material with good rigidity and bending resistance, which can be, but is not limited to, steel, alloys, etc. The smaller the thickness of the protective component 3, the better, effectively reducing the overall thickness of the connecting device, for example, 0.02mm. In this embodiment, the protective component 3 covers at least the part of the rotating arm 2 exposed relative to the base 5 or relative to the cover 12, or it can only cover and shield the rotating arm 2, or it can shield both the torque assembly 1 and the rotating arm 2 at the same time, so as to form a protective barrier layer between the electronic component 4 and the connecting device. Even if the rotating arm 2 or other parts of the torque assembly 1 generate resistance, it will be absorbed by the protective component 3 and will not affect the electronic component 4.

[0060] As described above, the connecting device provided in this application, by setting a deformable protective member 3 on the target side of the connecting component, enables the protective member 3 to deform with the relative movement of the rotating arm 2, preventing the connecting device from squeezing, abutting, or rubbing against the electronic component 4 on the target side, thus providing protection. Simultaneously, setting the protective member 3 on the connecting device does not affect the strength of the electronic component 4, and therefore does not affect its bending ability or service life. This solves the technical problem in existing foldable electronic devices where flexible screens are easily abutted or squeezed by the hinge, causing black spots (GDS). Furthermore, the protective member 3 covers the rotating arm 2 of the connecting device. When the connecting device is installed in the electronic device, the protective member 3 is only located within the bending area of ​​the electronic device, without adjoining or connecting to the non-bending area of ​​the electronic device or electronic component 4. Therefore, it does not occupy the structural space of the non-bending area, such as the bonding area between the display screen and the frame, thereby improving the connection stability of the display screen in the electronic device and preventing the display screen from being suspended due to the bonding area being occupied, thus avoiding water ripple phenomena on the display side and effectively improving the display effect.

[0061] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships, such as A and / or B. Specifically, it can be understood as: A and B can be included at the same time, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0062] Further, see Appendix Figure 1 In the specific implementation of the connection device provided in this embodiment, the protective member 3 also covers the cover 12 of the base 5. The protective member 3 is fixed to the cover 12 of the base 5, and the cover 12 of the base 5 is used to shield the torque assembly 11.

[0063] It is understandable that, in order to ensure the stable installation of the protective component 3, in this embodiment, the protective component 3 can be fixed to the cover 12 of the base 5. The base 5 and the cover 12 can be referred to the above description, and will not be repeated here. For details, please refer to the appendix. Figure 1 and attached Figure 4 The protective element 3 has two ends that shield the two rotating arms 2 located outside the cover 12, and the middle part of the protective element 3 shields the cover 12 located between the two rotating arms 2. In this embodiment, the protective element 3 can be fixedly connected to the cover 12, for example: Figure 1 The protective component 3 is bonded or welded to the cover 12 at the position corresponding to the two rotating arms 2, which can be, but is not limited to, by means of bonding or welding. Figure 1The dots arranged in the middle serve as connection points; correspondingly, the protective element 2 can be set to be free at the position of the two rotating arms 2, that is, not connected to any structure of the connecting device or electronic equipment. In this setting, when the protective element 3 deforms with the two rotating arms 2, it can perfectly match the deformation of the electronic component 4 and reduce the friction between the protective element 3 and the electronic component 4, i.e., the display screen. This avoids the situation where the protective element 3 is completely fixed to the rotating arms 2, and the rotating arms 2 move, causing the protective element 3 to deform accordingly, which would require more stress or movement tendency, thereby increasing the friction or contact between the protective element 3 and the electronic component 4, i.e., the display screen.

[0064] Further, see Appendix Figure 4 and attached Figure 5 The connecting device provided in this embodiment further includes two flat plates 6 in a specific implementation. The two flat plates 6 are slidably connected to the two rotating arms 2 respectively. The two rotating arms 2 are located in a first relative position, and the two flat plates 6 form a first plane. The first plane and the first surface on the protective member 3 facing the target side belong to the same surface. The protective member 3 also covers a portion of the side of the flat plate 6 facing the rotating arm 2 on the first surface of each of the two flat plates 6 facing the target side. The two rotating arms 2 are located in a second relative position, and the first space formed by the two flat plates 6 drives the protective member 3 to deform into the target shape and drives the display screen to change into the target shape.

[0065] Understandably, in order to limit the bending of the electronic component 4 (i.e., the display screen) on the folding electronic device using the connecting device, two flat plates 6 are provided in the connecting device in this embodiment. The flat plates 6 are rigid structures, and are slidably connected to the rotating arm 2 at the end away from the torque component 1. They are used to slide along the rotating arm 2 away from the torque component 1 when the two rotating arms 4 approach each other, so as to cooperate with the rotating arm 2 to constrain and limit the electronic component 4 (i.e., the display screen). Refer to the attached figure. Figure 8 The plate 6 is provided with a third slide rail 61. The end of the rotating arm 2 away from the torque assembly 1 is provided with a slider 21 adapted to the third slide rail 61. The third slide rail 61 is arc-shaped to ensure that when the plate 6 slides relative to the rotating arm 2, the end away from the rotating arm 2 can approach the other plate 6. (See attached diagram) Figure 4When the two rotating arms 2 are in the first relative position, that is, when the two rotating arms 2 and the torque assembly 1 satisfy the parallel condition and the two rotating arms 2 are also parallel to each other, the two rotating arms 2 are in a flattened state relative to the torque assembly 1. At this time, the plate 6 is also in a flattened state. Therefore, the surface of the plate 6 facing the target side, that is, the side facing the electronic component 4, together constitutes the first plane. In this state, the protective member 3 is also in a flattened state, so its surface facing the target side and the first plane belong to the same plane. The protective member 3 can cover the end of the plate 6 facing the torque assembly 1, or the protective member 3 can cover the entire plate 6. In this setting, it can not only ensure that when the two rotating arms 2 are in the first relative position, the surface of the protective member 3 facing the target side and the first plane belong to the same plane, but also ensure that when the two rotating arms 2 are in the second relative position, the end of the protective member 3 facing the plate 6 will not interfere with the plate 6. Accordingly, refer to the appendix. Figure 5 When the two rotating arms 2 move to the second relative position, that is, when the two rotating arms 2 satisfy the parallel condition and the two rotating arms 2 satisfy the perpendicular condition with the torque component 1, the two flat plates 6 slide along the rotating arms 2 away from the torque component 1 along the third slide rail 61 as the two rotating arms 4 approach each other to form a figure-eight relative state. The distance between the two rotating arms 2 is approximately the distance between the two rotating shafts. Then, the two flat plates 6 cooperate with the two rotating arms 2 to form a first space that is smaller at the top and larger at the bottom. Then, the electronic component 4, i.e. the display screen, is constrained and limited to make the display screen bend into a shape that is smaller at the top and larger at the bottom, such as a teardrop shape. It is not difficult to understand that the target shape is smaller at the top and larger at the bottom, like a teardrop, to meet the folding requirements of the folding device.

[0066] Further, see Appendix Figure 6 and attached Figure 7 The connecting device provided in this embodiment further includes a trajectory component 51 and two trajectory arms 7 in a specific implementation. The trajectory component 51 is located within the base 5 and provides a motion trajectory. The trajectory arm 7 includes a motion end 71 that cooperates with the motion trajectory and a motion arm 72 located outside the base 5. The motion arm 72 is slidably connected to the plate 6 and is used to drive the two plates 6 to move in the same way. The protective member 3 at least covers the target side of the two trajectory arms 7, and the target side of the trajectory arm 7 is the same side as the target side of the rotating arm 2.

[0067] It is understandable that, in order to constrain and limit the movement of the display screen by the movement of the flat plate 6 with the rotation arm 2, a trajectory component 51 is provided on the base 5 in this embodiment, and a trajectory arm 7 is provided in conjunction with it; the trajectory component 51 is provided with a groove, slide, or guide rail on the base 5 corresponding to the trajectory arm 7; the trajectory arm 7 is a rigid structure, and it is spaced apart from the rotation arm 2 along the axial direction of the torsion component 1; the two trajectory arms 7 can be symmetrically arranged relative to the torsion component 1 or staggered along the axial direction of the torsion component 1; see attached figure. Figure 6 When the two track arms 7 are symmetrically arranged relative to the torque component 1, the cover 12 of the base 5 can be left uncovered, allowing the track arms 7 to be fully exposed outside the base 5. Alternatively, as with the arrangement of the rotating arm 2, an opening can be made in the cover 12 to expose the track arms 7. In this embodiment, the rotating arm 2 is rotated at one end facing the torque component 1 and slidably arranged at the other end away from the torque component 1. Correspondingly, in order to cooperate with the rotating arm 2 and allow the plate 6 to slide along the arc of the third slide rail 61, the track arm 7 can be slidably arranged at one end facing the torque component 1 in conjunction with the track component 51, and rotated at the other end away from the torque component 1. Furthermore, in this embodiment, the track arm 7 can also be slidably connected to the plate 6, such as... Figure 9 As shown, a sliding hole 62 is provided on the plate 6, and a protrusion 73 is provided on the track arm 7 corresponding to the sliding hole 62. This not only guides the movement of the plate 6 but also limits the range of movement of the plate 6, avoiding excessive compression and restriction of the display screen. It is easy to understand that when the two rotating arms 2 are in the first relative position, the sliding hole 62 tilts from the plate 6 towards the rotating arm 2 and away from the torque component 1, so as to cooperate with the subsequent movement of the plate 6 to form a figure-eight shape. The specific tilt angle can be designed and adjusted according to actual needs. It is easy to understand that in this embodiment, the movement of the rotating arm 2 can be driven by the plate 6 to move the track arm 7 within the track component 51 according to the movement trajectory provided by the track component 51, so that the rotating arm 2 also moves according to the movement trajectory. This movement trajectory can also move the two plates 6 to form the aforementioned first plane and first space. Correspondingly, in this embodiment, the protective member 2 can cover the rotating arm 2 and the track arm 7 at the same time, preventing the target side of the track arm 7 from contacting, rubbing, or squeezing the electronic component 4, i.e., the display screen, effectively protecting the electronic component 4, i.e., the display screen.

[0068] Accordingly, see Appendix Figure 10 To achieve the coordinated movement of the rotating arm 2, the trajectory arm 7, and the plate 6 to constrain and limit the electronic component 4 (i.e., the display screen) to form the target shape, this embodiment may also include a first connecting component 8 and a second connecting component 9. The first connecting component 8 and the second connecting component 9 are each configured to correspond to one rotating arm 2. The first connecting component 8 and the second connecting component 9 are used to fix and connect two relatively rotatable or foldable bodies in the electronic device; that is, the first connecting component 8 and the second connecting component 9 are the connecting carriers between the connecting device and the electronic device. The first connecting component 8 and the second connecting component 9 are rigid structures and can be, but are not limited to, plates, blocks, frames, etc. In this embodiment, the first connecting component 8 and the second connecting component 9 have the same structure; the following description will use the first connecting component 8 as an example. (See attached...) Figure 8When the two rotating arms 2 are in the first relative position, the plate 6 and the first connecting assembly 8 are respectively located on the target side and the side opposite to the target side of the rotating arm 2, that is, a receiving space or connecting space is formed between the plate 6 and the first connecting assembly 8, accommodating the rotating arm 2 and the track arm 7 between them. (See attached diagram) Figure 10 and attached Figure 11 The first connecting component 8 is provided with a first slide rail 81 to accommodate the sliding of the rotating arm 2. Referring to the above, it can be seen that the end of the rotating arm 2 furthest from the torque component 1 simultaneously slides between the plate 6 and the first connecting component 8. Figure 8 and Figure 12 As shown in the diagram; the trajectory arm 7 is rotatably connected to the end of the first connecting assembly 8 away from the torque assembly 1 via a rotating shaft. Referring to the above, it can be seen that the trajectory arm 7 is slidably fitted to the base 5 and the sliding plate 6, and rotatably connected to the first connecting assembly 8. Figure 9 and Figure 10 The state shown; at the same time, refer to the appendix. Figure 13 In order to ensure the smooth movement of the aforementioned plate 6, a second slide rail 82 can be provided on the first connecting component 8 in this embodiment. The plate 6 is equipped with a slide rod 63. The second slide rail 82 is arc-shaped and can have the same arc as the third slide rail 61, so as to enable the two plates 6 to move to form a figure-eight shape.

[0069] Further, see Appendix Figure 4 and attached Figure 5 In the specific implementation of the connection device provided in this embodiment, the rotating arm 2 includes an arc segment 22, and the protective member 3 prevents the arc segment from affecting the display screen when the two rotating arms 2 are in the second relative position.

[0070] It is understandable that, in order to cooperate with the tablet 6 in constraining and limiting the electronic component 4, i.e., the display screen, to form the target shape, the rotating arm 2 in this embodiment can be configured to include an arc segment 22. When the two rotating arms 2 are in the first relative position, the arc segment 22 protrudes towards the target side, and the opposite side of the arc segment 22 is used to avoid the related structure of the base 5, preventing interference when the two rotating arms 2 are flattened relative to each other. When the two rotating arms 2 rotate to the second relative position, the two arc segments 22 protrude towards each other so that the distance between the two arc segments 22 is less than the distance between the rotation axes of the two rotating arms 2, or less than the width of the base 5 in the direction between the two rotating arms 2. At this time, the arc segment 22 can limit the display screen; therefore, the protective member 3 in this embodiment must at least cover and block the target side of the arc segment 22. Accordingly, in this embodiment, the rotating arm 22 can Figure 3The diagram shows an L-shaped structure. When the rotating arm 2 rotates to the second relative position, the turning points of the L-shaped structures of the two rotating arms 2 are set facing each other. As a result, the space size of the first space at this position is relatively large, thus forming a first space that is smaller at the top and larger at the bottom with the two flat plates 6. The straight segments of the rotating arm 2 are used to slide and engage with the flat plates 6. The sliding engagement between the two flat plates 6 and the straight segments of the two rotating arms 2 makes the straight segments of the two rotating arms 2 form a figure-eight shape when the two rotating arms 2 are in the second relative position, and the two flat plates 6 also form a figure-eight shape.

[0071] Example 2

[0072] Reference Appendix Figure 14 This embodiment provides an electronic device, which includes a first body 101, a second body 102, a display screen, and a connecting device. The second body 102 is rotatably connected to the first body 101 via the connecting device. The display screen is deformable and is connected to both the first body 101 and the second body 102 across the connecting device. The display screen can deform as the first body 101 and the second body 102 rotate relative to each other. The protective member 3 of the connecting device corresponds to the display screen and can deform as the first body 101 and the second body 102 rotate relative to each other to protect the display screen.

[0073] It is understood that the electronic device provided in this embodiment can be a foldable electronic device, such as a foldable mobile phone, a laptop computer, etc. The first body 101 and the second body 102 are two parts that can rotate or fold relative to each other. For example, the two-part body structure of a foldable mobile phone, which sets up the motherboard and the small board, or the system end and the display end of a laptop computer. In this embodiment, the system end of the laptop computer can also be covered by the display screen to form a touch input mode. The display screen is a flexible display screen.

[0074] The connecting device is the one described in this embodiment. Its structure and working principle are detailed in Embodiment 1 and will not be repeated here. Correspondingly, the two rotating arms 2 of the connecting device are movably connected to the first body 101 and the second body 102, respectively. The relative movement of the two rotating arms 2 can cause the two bodies to move relative to each other. When the two rotating arms 2 are in the first relative position, the two bodies and the display screen are in a flattened state, i.e., the electronic device is in a first posture. When the two rotating arms 2 are in the second relative position, the two bodies and the display screen are in a folded state, i.e., the electronic device is in a second posture. In this configuration, the protective member 3 is placed on the side of the connecting device facing the display screen, and can deform with the relative rotation of the first body 101 and the second body 102 to protect the display screen. In the electronic device of this embodiment, the number of connecting devices can be designed and adjusted according to actual needs. For example, one can be set in the middle of the folding axis of the two bodies, one can be set at each end of the folding axis of the two bodies, or multiple devices can be set at intervals along the folding axis of the two bodies, etc.

[0075] Furthermore, the protective element 3 at least covers the portion of the connecting device exposed relative to the base 5.

[0076] Understandably, in order to avoid the structural components in the connecting device causing sharp point contact or friction to the display screen when the display screen is deformed or folded, in this embodiment, the protective component 3 is set to at least cover the part of the connecting device exposed relative to the base 5, which may include, but is not limited to, the part of the rotating arm 2 exposed relative to the base 5. Thus, the protective component 3 forms a barrier structure between the base 5 and the display screen, preventing the structure of the connecting device that is exposed outside the base 5 from causing sharp point contact or friction to the display screen.

[0077] Further, see Appendix Figure 10 and attached Figure 11In this embodiment, the electronic device includes two connecting components, two flat plates 6, two rotating arms 2, and two track arms 7. The two connecting components are fixedly connected to the first body 101 and the second body 102, respectively. Each connecting component includes a first slide rail 81. Each of the two flat plates 6 is movably connected to one of the connecting components. The two rotating arms 2 are slidably engaged with the first slide rails 81 of the two connecting components. The two track arms 7 are rotatably engaged with the two connecting components. In a first posture, the two flat plates 6 form a first plane, which is the same as the first surface of the protective member 3 facing the display screen. In a second posture, the two flat plates 6 form a first space, which drives the protective member 3 to deform into the target shape and drives the display screen into the target shape. The protective member 3 covers a portion of the first surface of the two rotating arms 2, the two track arms 7, and the two flat plates 6 facing the display screen, including the side of the flat plate 6 facing the rotating arm 2.

[0078] Understandably, in order to achieve both the deformation of the protective component in coordination with the movement of the connecting device and the protection of the display screen, the connecting device in this embodiment can be configured to include a first connecting component 8, a second connecting component 9, two rotating arms 2, two flat plates 6, and two track arms 7, i.e., with... Figure 10 and attached Figure 12 As shown; the arrangement of the two rotating arms 2, two flat plates 7, and two track arms 7 is described in detail in Embodiment 1, and will not be repeated here. The first connecting component 8 and the second connecting component 9 are respectively configured for one rotating arm 2. The first connecting component 8 and the second connecting component 9 are used to fix and connect the first body 101 and the second body 102, respectively; that is, the first connecting component 8 and the second connecting component 9 are the connecting carriers between the connecting device and the electronic device. The first connecting component 8 and the second connecting component 9 are rigid structures, and can be, but are not limited to, plates, blocks, frames, etc. In this embodiment, the first connecting component 8 and the second connecting component 9 have the same structure; the following description will use the first connecting component 8 as an example. (Refer to Appendix) Figure 8 When the two rotating arms 2 are in the first relative position, i.e., the electronic device is in the first posture, the plate 6 and the first connecting component 8 are respectively located on the target side and the side opposite to the target side of the rotating arm 2, that is, a receiving space or connecting space is formed between the plate 6 and the first connecting component 8, accommodating the rotating arm 2 and the trajectory arm 7 between them. (See attached diagram) Figure 10 and attached Figure 11The first connecting component 8 is provided with a first slide rail 81 to accommodate the sliding of the rotating arm 2, providing a motion trajectory guide for the rotating arm 2. Referring to the above, it can be seen that the end of the rotating arm 2 furthest from the torque component 1 is simultaneously slidably connected to the plate 6 and the first connecting component 8. Figure 8 and Figure 12 As shown in the diagram; the trajectory arm 7 is rotatably connected to the end of the first connecting assembly 8 away from the torque assembly 1 via a rotating shaft. Referring to the above, it can be seen that the trajectory arm 7 is slidably fitted to the base 5 and the sliding plate 6, and rotatably connected to the first connecting assembly 8. Figure 9 and Figure 10 The state shown; at the same time, refer to the appendix. Figure 13 To ensure smooth movement of the aforementioned flat plate 6, a second slide rail 82 can be provided on the first connecting component 8 in this embodiment. This is in conjunction with the slide rod 63 on the flat plate 6. The second slide rail 82 is arc-shaped, and its curvature can be the same as that of the third slide rail 61, to facilitate the movement of the two flat plates 6 into a figure-eight shape. Simultaneously, to ensure comprehensive protection of the display screen by the protective component 3, in this embodiment, the protective component 3 can be configured to simultaneously cover the first surface of each of the two rotating arms 2, the two track arms 7, and the first surface of each of the two flat plates facing the display screen, including a portion of the side of the flat plate 6 facing the rotating arm 2. Correspondingly, for the electronic device, refer to the attached... Figure 1 When a connecting device is provided at each end of the rotation axis of the first body 101 and the second body 102, a protective member 3 can be provided for each connection state, or a longer protective member 3 can be provided to cover the target side of the two connecting devices at the same time.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
