Description

Technical Field

[0001] This application relates to the field of electronic product technology, and more particularly to a folding mechanism and an electronic device. Background Technology

[0002] Compared to electronic devices with only one rotating mechanism, foldable electronic devices with three or more folds, that is, electronic devices that increase the display size by unfolding two or more times, are gradually becoming a development trend in electronic devices.

[0003] Electronic devices with three-fold or multi-fold structures have complex motion mechanisms and various folding methods. If users use an inappropriate folding sequence, it may cause pressure or impact on the display screen, affecting the screen's lifespan. Summary of the Invention

[0004] This application provides a folding mechanism and an electronic device that solves the problem of display screen failure caused by incorrect closing sequence of a three-fold screen.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A first aspect of this application provides a folding mechanism for supporting a display screen. The folding mechanism includes: a first structural member, a first rotating mechanism, a second structural member, a second rotating mechanism, and a third structural member connected sequentially. The first structural member and the second structural member are capable of being unfolded or folded relative to each other via the first rotating mechanism, and the second structural member and the third structural member are also capable of being unfolded or folded relative to each other via the second rotating mechanism. The second rotating mechanism includes a groove, and the second structural member includes an accommodating space containing a protrusion, the accommodating space being disposed near the second rotating mechanism. During the process of the first structural member and the second structural member being in an open state, and the second structural member and the third structural member being folded relative to each other from the open state to a first folded state via the second rotating mechanism, the first end of the protrusion is located within the groove, providing resistance to the folding of the second structural member and the third structural member relative to the second rotating mechanism. The first structural member and the second structural member are in an open state, and the second structural member and the third structural member are in a folded state. Therefore, when the user folds the electronic device in the wrong order, the bumps can provide resistance to the folding, providing a damping feel and reminding the user that the closing sequence is incorrect. This helps the user fold the electronic device in the correct order and increases its lifespan.

[0007] In one optional implementation, the folding mechanism further includes a moving component disposed within the accommodating space. During the process of the first and second structural components folding relative to each other from the open state to the second folded state via the first rotating mechanism when the second and third structural components are in the open state, the moving component moves away from the second structural component, forming a clearance space within the accommodating space. In the second folded state, the first and second structural components are folded, and the second and third structural components are open. The distance between the first end of the protrusion and the second rotating mechanism is less than the distance between the second end of the protrusion and the second rotating mechanism. This allows the second end of the protrusion to enter the clearance space, the first end of the protrusion to disengage from the groove, and the second and third structural components to rotate smoothly relative to the second rotating mechanism. That is, when the electronic device is closed in the correct sequence, it can be closed smoothly.

[0008] In one alternative implementation, the moving component and the protrusion move in different directions. As the moving component moves away from the second structural member, it drives the protrusion to move, causing the second end of the protrusion to enter the clearance space, while the first end of the protrusion moves away from the groove. Thus, the moving component and the protrusion move in different directions, allowing them to move collaboratively without affecting each other.

[0009] In one alternative implementation, the moving component is fixedly connected to the protrusion, and the moving component moves in the same direction as the protrusion. The moving component drives the protrusion to move, causing the second end of the protrusion to enter the clearance space, while the first end of the protrusion moves away from the groove. Thus, the moving component and the protrusion move in the same direction, resulting in a simple structure.

[0010] In one alternative implementation, the moving component is not connected to the protrusion. During the process of the second structural component and the third structural component folding from the open state to the second folded state via the second rotating mechanism, the second end of the protrusion enters the clearance space, and the first end of the protrusion moves away from the groove. Thus, the second rotating mechanism can push the second end of the protrusion into the clearance space, and the first end of the protrusion moves away from the groove. The moving component is decoupled from the protrusion, resulting in a simpler structure.

[0011] In one optional implementation, the folding mechanism further includes a first magnetic component and a second magnetic component. The first magnetic component is fixed to the first structural component, and the second magnetic component is located within the clearance space and connected to the moving component. An attractive force exists between the first and second magnetic components. When the first and second structural components are in an open state, and the second and third structural components are in an open state, a gap exists between the first and second magnetic components. During the process of folding the first and second structural components from the open state to the second folded state via the first rotating mechanism, the second magnetic component, under the influence of the attractive force, drives the moving component to move closer to the first structural component, forming a clearance space within the second structural component. Thus, the magnetic component can drive the moving component to form a clearance space to accommodate the protrusion, facilitating the smooth opening and closing of the electronic device.

[0012] In one optional implementation, the folding mechanism further includes a bracket located within the accommodating space and connected to the second structural member. The bracket also includes a first guide portion, with the moving member slidably connected to the first guide portion. Thus, the first guide portion can guide the moving member, facilitating its sliding along a preset direction.

[0013] In one alternative implementation, the extension direction of the first guide portion is perpendicular to the plane containing the second structural member. This allows the moving member to slide along a direction perpendicular to the plane containing the second structural member, which helps to shorten the movement distance, improve response speed, and enhance the driving effect.

[0014] In one alternative implementation, the bracket further includes a second guide portion, to which the protrusion is slidably connected. Thus, the second guide portion can be used to guide the protrusion, facilitating its sliding along a preset direction.

[0015] In one alternative implementation, the first guide portion is a guide rod, and the second guide portion is a guide groove. Alternatively, the first guide portion is a guide groove, and the second guide portion is a guide rod. This simplifies the structure of the guide portion and reduces manufacturing complexity.

[0016] In one optional implementation, the extension direction of the second guide portion is perpendicular to the extension direction of the first guide portion, and the extension direction of the second guide portion is also perpendicular to the axial direction of the second rotating mechanism. This allows the protrusion to slide in a direction perpendicular to the axial direction of the second rotating mechanism, which helps to shorten the movement distance, improves the response speed, and provides a better driving effect.

[0017] A second aspect of this application provides an electronic device including a display screen and a folding mechanism as described above. The folding mechanism is disposed on the side opposite to the light-emitting surface of the display screen, and the display screen is connected to the folding mechanism. Thus, by employing the aforementioned folding structure, when the user closes the electronic device in an incorrect sequence, the peak closing force of the second rotating mechanism can be briefly increased to alert the user of the incorrect closing sequence. When the user closes the electronic device in the correct sequence, the peak closing force of the second rotating mechanism returns to normal, without affecting normal user operation.

[0018] In one optional implementation, the display screen includes a first non-bending area, a first bending area, a second non-bending area, a second bending area, and a third non-bending area connected sequentially. The first non-bending area is connected to the first structural member; the first bending area corresponds to the first rotating mechanism; the second non-bending area is connected to the second structural member; the second bending area corresponds to the second rotating mechanism; and the third non-bending area is connected to the third structural member. Thus, the connection between the display screen and the folding mechanism provides better protection for the display screen.

[0019] In one optional implementation, the electronic device includes a first folded state and a second folded state. In the first folded state, the first non-bending area and the second non-bending area are in an open state, and the second non-bending area and the third non-bending area are in a folded state. Therefore, the first folded state is the state resulting from closing in an incorrect sequence.

[0020] In one optional implementation, the electronic device includes: a second folded state, in which the first non-bending area and the second non-bending area are folded, and the second non-bending area and the third non-bending area are open.

[0021] In one optional implementation, the electronic device includes a third folded state, in which the first non-bending area and the second non-bending area are folded, and the second non-bending area and the third non-bending area are folded, with the first non-bending area located between the second and third non-bending areas. Thus, this third folded state represents the state after all parts are fully closed using the correct folding sequence. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0036] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0037] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0038] This application provides an electronic device, which can be a foldable electronic device such as a mobile phone, monitor, tablet computer, in-vehicle computer, watch, e-reader, laptop computer, or wearable device. This application does not impose any special limitations on the specific form of the above-mentioned electronic device. Figure 1 The illustrated embodiment uses a foldable phone as an example.

[0039] To facilitate understanding of the electronic equipment provided in the embodiments of this application, the following description is provided in conjunction with the accompanying drawings. Figure 1 The following is a description of an existing electronic device:

[0040] Figure 1 This is a schematic diagram of an electronic device in an open state, provided as an embodiment of this application. Figure 1 As shown, the electronic device 1 includes a flexible display screen 10. The flexible display screen 10 can be an active matrix organic light emitting diode (AMOLED) display screen.

[0041] As a self-emissive display, AMOLED displays do not require a backlight module (BLM). Therefore, when the substrate of an AMOLED display is made of a flexible resin material, such as polyethylene terephthalate (PET), the AMOLED display can be bent.

[0042] In this embodiment, a three-fold structure of the electronic device is used as an example for explanation. That is, the electronic device includes three structural components, with adjacent structural components connected by a rotating mechanism. Adjacent structural components can rotate relative to each other to overlap, giving the electronic device a two- or three-layer configuration (corresponding to the first folded state or the second folded state). Adjacent flat sections can also rotate away from each other to flatten, giving the electronic device an open state. In other embodiments, the electronic device may have a four-fold or more fold structure, that is, the electronic device includes four or more structural components, with adjacent structural components connected by a rotating mechanism. Adjacent structural components can rotate relative to each other to overlap or away from each other to flatten. When the electronic device has a four-fold or more fold structure, the structure of the electronic device can be adapted to the description of the three-fold structure in this embodiment, and this application will not elaborate further.

[0043] In addition, such as Figure 1 As shown, the electronic device 1 also includes a folding mechanism 20 for supporting the flexible display screen 10.

[0044] The folding mechanism 20 includes a first structural member 201, a second structural member 202, a third structural member 203, a first rotating mechanism 204 disposed between the first structural member 201 and the second structural member 202, and a second rotating mechanism 205 disposed between the second structural member 202 and the third structural member 203.

[0045] The first structural component 201, the second structural component 202, and the third structural component 203 can be used to support the flexible display screen 10, so that the flexible display screen 10 remains as flat as possible during use and protects the non-display surface of the flexible display screen 10.

[0046] The flexible display screen 10 is fixed to the folding mechanism 20, for example. Other electronic components, such as cameras, headphones, earpieces, buttons, batteries, etc., may also be provided on the first structural member 201, the second structural member 202, and the third structural member 203. This application embodiment does not limit the other electronic components provided on the first structural member 201 and the second structural member 202.

[0047] In some embodiments, the flexible display screen 10 may include a first non-bending area 101 corresponding to the first structural member 201, a second non-bending area 102 corresponding to the second structural member 202, a third non-bending area 103 corresponding to the third structural member 203, a first bending area 104 corresponding to the first rotating mechanism 204, and a second bending area 105 corresponding to the second rotating mechanism 205. The first bending area 104 may be connected between the first non-bending area 101 and the second non-bending area 102, and the second bending area 105 may be connected between the second non-bending area 102 and the third non-bending area 103.

[0048] The first non-bending area 101 can be connected to the first structural member 201, the second non-bending area 102 can be connected to the second structural member 202, and the third non-bending area 103 can be connected to the third structural member 203.

[0049] In some embodiments, the first structural member 201, the second structural member 202, and the third structural member 203 are housing members used to install and fix other components of electronic devices and have diverse structures. The embodiments of this application only briefly illustrate some of the structures of the first structural member 201, the second structural member 202, and the third structural member 203, and the accompanying drawings are also simplified. The embodiments of this application do not strictly limit the specific structures of the first structural member 201, the second structural member 202, and the third structural member 203.

[0050] In other embodiments, the first structural member 201 may include a first middle frame and a first rear cover. The first middle frame is connected to one side of the first rotating mechanism 204, and the first rear cover is located below and fixedly connected to the first middle frame. The first rear cover forms part of the appearance of the electronic device. For example, the first rear cover may be a protective cover for protecting devices located inside the first structural member 201 and for presenting part of the appearance of the electronic device. In other embodiments, the first rear cover may also include a transparent cover and a display screen to realize display and / or touch functions.

[0051] The second structural member 202 may include a second middle frame and a second rear cover. The second middle frame is connected to the other side of the first rotating mechanism 204, and the second rear cover is located below and fixedly connected to the second middle frame. The second rear cover forms part of the appearance of the electronic device. For example, the second rear cover may be a protective cover for protecting devices located inside the second structural member 202 and also for presenting part of the appearance of the electronic device. In some other embodiments, the second rear cover may also include a transparent cover and a display screen to achieve display and / or touch functionality.

[0052] The third structural member 203 may include a third middle frame and a third rear cover. The third middle frame is connected to the other side of the second rotating mechanism 205, and the third rear cover is located below and fixedly connected to the third middle frame. The third rear cover forms part of the appearance of the electronic device. For example, the third rear cover may be a protective cover for protecting devices located inside the third structural member 203 and also for presenting part of the appearance of the electronic device. In some other embodiments, the third rear cover may also include a transparent cover and a display screen to achieve display and / or touch functionality.

[0053] At least one of the first, second, and third middle frames may include both metal and plastic components, and is integrally formed using in-mold decoration (IMD) molding. When at least one of the first, second, and third rear covers is a protective cover, it may be made of glass or metal, and this application does not impose any limitations on this.

[0054] The first, second, and third middle frames each include a border portion and a middle plate portion. The border portion forms part of the appearance of the electronic device, and the middle plate portion is located inside the border portion. The middle plate portion may have multiple protrusions, grooves, or other mounting structures for cooperating with other components of the electronic device so that the other components are mounted on at least one of the middle frames of the first, second, and third middle frames.

[0055] In this application, a first rotating mechanism 204 connects a first structural member 201 and a second structural member 202. Under the action of the first rotating mechanism 204, the first structural member 201 and the second structural member 202 can move closer to or further away from each other. Correspondingly, the first non-bending area 101 and the second non-bending area 102 of the flexible display screen 10 can move closer to or further away from each other, so that the flexible display screen 10 can be folded or unfolded.

[0056] The second rotating mechanism 205 connects the second structural member 202 and the third structural member 203. Under the action of the second rotating mechanism 205, the second structural member 202 and the third structural member 203 can move closer to each other or further away from each other. Correspondingly, the second non-bending area 102 and the third non-bending area 103 of the flexible display screen 10 can move closer to each other or further away from each other, so that the flexible display screen 10 can be folded or unfolded.

[0057] The electronic device includes an open state, a folded state, and an intermediate state. An intermediate state of the electronic device is, for example, the state between the open state and the folded state.

[0058] like Figure 1As shown, when the electronic device is in the open state, the first structural member 201 and the second structural member 202 are both in the open state, as are the second structural member 202 and the third structural member 203. The included angles between the first structural member 201 and the second structural member 202, and between the second structural member 202 and the third structural member 203, can all be approximately 180°. The first structural member 201, the second structural member 202, and the third structural member 203 are all flattened, and the display screen 10 presents a flattened shape. In some other embodiments, when the electronic device is in the open state, the angle between the first structural member 201 and the second structural member 202, and / or the angle between the second structural member 202 and the third structural member 203, may also deviate slightly from 180°, such as 165°, 177°, or 185°. In this case, the first structural member 201, the second structural member 202, and the third structural member 203 are also considered to be flattened. The angle between the first structural member 201 and the second structural member 202 is defined as the angle between the upper sides of the first structural member 201 and the second structural member 202, and the angle between the second structural member 202 and the third structural member 203 is defined as the angle between the upper sides of the second structural member 202 and the third structural member 203. In this embodiment, the orientation that is the same as the light emission direction of the display screen 10 is defined as "up", and the orientation that is opposite to the light emission direction of the display screen 10 is defined as "down".

[0059] In some embodiments, the folding states include: a first folding state, a second folding state, a third folding state, and a fourth folding state.

[0060] Figure 2 for Figure 1 The diagram shows the structure of the electronic device in its first folded state. Figure 2 As shown, when the electronic device is in its first folded state, as Figure 2 As shown, the second structural member 202 and the third structural member 203 are in a folded state, while the first structural member 201 and the second structural member 202 are in an open state. The angle between the first structural member 201 and the second structural member 202 can be approximately 180°, and the angle between the second structural member 202 and the third structural member 203 can be approximately 0°. In some embodiments, the angle between the first structural member 201 and the second structural member 202 may deviate from 180°, and / or the angle between the second structural member 202 and the third structural member 203 may also deviate slightly from 0°, for example, by 3°, 5°, or 8°. This is also considered to indicate that the electronic device is in a first folded state.

[0061] Figure 3 for Figure 1 The diagram shows the structure of the electronic device in its second folded state. Figure 3As shown, when the electronic device is in the second folded state, the first structural member 201 and the second structural member 202 are folded, while the second structural member 202 and the third structural member 203 are open. The angle between the first structural member 201 and the second structural member 202 can be approximately 0°, and the angle between the second structural member 202 and the third structural member 203 can be approximately 180°. In some embodiments, the angle between the first structural member 201 and the second structural member 202 may deviate from 0°, and / or the angle between the second structural member 202 and the third structural member 203 may also deviate slightly from 180°, for example, by 3°, 5°, or 8°. This is also considered as the electronic device being in the second folded state.

[0062] Figure 4 for Figure 1 The diagram shows the structure of the electronic device in its third folded state. Figure 4 As shown, when the electronic device is in its third folded state, the first structural member 201 and the second structural member 202 are folded, and the second structural member 202 and the third structural member 203 are folded. The angle between the first structural member 201 and the second structural member 202 can be approximately 0°, and the angle between the second structural member 202 and the third structural member 203 can also be approximately 0°. The display screen 10 is in a folded state. The first structural member 201 is located between the second structural member 202 and the third structural member 203. That is, when folding the electronic device, it is necessary to fold the first structural member 201 first and then the third structural member 203. The angle between the first structural member 201 and the second structural member 202 can be approximately 0°, and the angle between the second structural member 202 and the third structural member 203 can also be approximately 0°. In some embodiments, the angle between the first structural member 201 and the second structural member 202 may deviate from 0°, and / or the angle between the second structural member 202 and the third structural member 203 may also deviate slightly from 0°, such as by 3°, 5° or 8°, and in this case the electronic device is also considered to be in the third folded state.

[0063] Figure 5 for Figure 1 The diagram shows the structure of the electronic device in its fourth folded state. Figure 5As shown, when the electronic device is in the fourth folded state, the second structural member 202 and the third structural member 203 are folded, and the first structural member 201 and the second structural member 202 are in a semi-closed state. The angle between the first structural member 201 and the second structural member 202 can be approximately 135°, and the angle between the second structural member 202 and the third structural member 203 can be approximately 0°. In some embodiments, the angle between the first structural member 201 and the second structural member 202 may deviate from 135°, and / or the angle between the second structural member 202 and the third structural member 203 may also deviate slightly from 0°, for example, by 3°, 5°, or 8°, and this is also considered as the electronic device being in the first folded state.

[0064] In some embodiments of this application, the first rotating mechanism 204 can be a V-shaped shaft, and the second rotating mechanism 205 can be a U-shaped shaft. The external dimensions of the first rotating mechanism 204 and the second rotating mechanism 205 are different. For example, ... Figure 4 As shown, the first rotating mechanism 204 has a first external surface 300, and the maximum dimension of the first external surface 300 in the thickness direction is defined as a first thickness d1. The second rotating mechanism 205 has a second external surface 400, and the maximum dimension of the second external surface 400 in the thickness direction is defined as a second thickness d2. When the electronic device is in the closed state, the first external surface 300 of the first rotating mechanism 204 is exposed relative to the first structural member 201 and the second structural member 202, and the first external surface 300 forms part of the external surface of the electronic device. The second external surface 400 of the second rotating mechanism 205 is exposed relative to the second structural member 202 and the third structural member 203, and the second external surface 400 forms part of the external surface of the electronic device.

[0065] Among them, such as Figure 4 As shown, the first thickness d1 of the first outer surface 300 of the first rotating mechanism 204 is less than the second thickness d2 of the second outer surface 400 of the second rotating mechanism 205. Furthermore, the second thickness d2 of the second outer surface 400 is approximately equal to the sum of the dimensions of the first structural member 201, the second structural member 202, and the third structural member 203 in the thickness direction. Therefore, if the third structural member 203 is folded before the first structural member 201 is folded, there is no support from the first structural member 201 between the third structural member 203 and the second structural member 202. The second rotating mechanism 205 will then struggle to support the third structural member 203 alone and will be subjected to excessive pressure, thereby damaging the second rotating mechanism 205.

[0066] To achieve the fourth folded state of the electronic device, the third structural member 203 needs to be folded first, followed by the first structural member 201. This adds a third structural member 203 between the first structural member 201 and the second structural member 202. The third structural member 203 abuts against the first non-bending area 101 of the flexible display screen 10, preventing the electronic device from fully closing and thus placing it in the fourth folded state. Figure 5 The fourth folded state shown in the diagram causes excessive tension on the first rotating mechanism 204 and excessive pressure on the flexible display screen 10, thereby damaging the first rotating mechanism 204 and the flexible display screen 10.

[0067] Therefore, this application provides an improved folding mechanism that allows the user to briefly increase the closing peak force of the second rotating mechanism 205 during the process of closing the third structural member 203 first, to indicate to the user that the closing sequence is incorrect. After the user closes the first structural member 201 first, the closing peak force of the second rotating mechanism 205 returns to normal, without affecting the normal closing of the third structural member 203.

[0068] The folding mechanism provided in this application embodiment is used to support a display screen. The folding mechanism includes a first structural member 201, a first rotating mechanism 204, a second structural member 202, a second rotating mechanism 205, and a third structural member 203 connected in sequence.

[0069] The first structural member 201 and the second structural member 202 can be relatively unfolded or folded through the first rotating mechanism 204, and the second structural member 202 and the third structural member 203 can be relatively unfolded or folded through the second rotating mechanism 205. The structures of the first structural member 201, the second structural member 202, the third structural member 203, and the first rotating mechanism 204 are as described in the above embodiments and will not be repeated here.

Figure 7 As shown, the second rotating mechanism 205 includes a groove 21, and the second structural member 202 includes an accommodating space 22, which is disposed near the second rotating mechanism 205.

[0072] The damping mechanism 1000 includes a protrusion 23 disposed within the accommodating space 22. The protrusion 23 includes a first end 231 and a second end 232 opposite to each other. The first end 231 of the protrusion 23 is closer to the second rotating mechanism 205 relative to the second end 232 of the protrusion 23. The protrusion 23 can move relative to the second rotating mechanism 205 in the x-direction, for example, it can move closer to or further away from the second rotating mechanism 205.

[0073] This application does not limit the structure of the second rotating mechanism 205. In some embodiments, the second rotating mechanism 205 includes a main shaft 2001 and a cover 2002, the cover 2002 being fixed to the main shaft 2001 and used to protect the main shaft 2001.

[0074] In some embodiments, the groove 21 may be formed by the main shaft 2001 and the cover 2002, such as Figure 8 As shown, the groove 21 includes a first opening 210, which faces, for example, the second structural member 202.

[0075] In some embodiments, the accommodating space 22 includes a second opening 220 facing the second rotating mechanism 205.

[0076] In some embodiments, the first opening 210 and the second opening 220 are opposite to each other. In this embodiment, the opposite can be directly opposite or there can be a deviation, such as a preset angle, which can be 5°, 10°, 15°, etc.

[0077] The protrusion 23 can slide within the receiving space 22. For example, the protrusion 23 can slide towards or away from the groove 21. In some embodiments, such as Figure 7 As shown, when the protrusion 23 slides to the first preset position, the first end 231 of the protrusion 23 is located in the groove 21. At this time, the protrusion 23 interferes with the main shaft 2001, which can provide resistance to the rotation of the second structural member 202 and the third structural member 203 relative to the second rotating mechanism 205.

[0078] In this embodiment, in order to enable the user to close the electronic device in the correct order, resistance can be provided when the user closes the electronic device in the wrong order.

[0079] For example, when the first structural member 201 and the second structural member 202 are in the open state, and the second structural member 202 and the third structural member 203 are folded relative to each other from the open state to the first folded state via the second rotating mechanism 205, the first end 231 of the protrusion 23 can be located within the groove 21, providing resistance to the folding of the second structural member 202 and the third structural member 203 relative to the second rotating mechanism 205. Thus, when the user closes the third structural member 203 first, the protrusion 23 provides resistance to the closing, increasing the user's feel and alerting the user that the closing sequence is incorrect.

[0080] The folding mechanism provided in this application embodiment can provide resistance to folding through the protrusion 23 when the user folds in the wrong order, thereby increasing the user's feel and reminding the user that the closing order is incorrect. This helps the user fold the electronic device in the correct order and increases the service life of the electronic device.

[0081] This application embodiment does not limit the shape of the protrusion 23 and the groove 21. The shape of the first end 231 of the protrusion 23 can be adapted to the shape of the groove 21. In some embodiments, such as Figure 8 As shown, the groove 21 includes a first inclined surface 2000, and the protrusion 23 includes a second inclined surface 2310. The shapes of the first inclined surface 2000 and the second inclined surface 2310 are adapted to each other. The first inclined surface 2000 can form a groove 21 with other parts of the main shaft 2001, and the shape of the first end 231 is adapted to the shape of the groove 21. During the process of the first structural member 201 and the second structural member 202 being in the open state, and the second structural member 202 and the third structural member 203 being folded relative to each other from the open state to the first folded state via the second rotating mechanism 205, the first end 231 of the protrusion 23 is located in the groove 21, and the first inclined surface 2000 and the second inclined surface 2310 can slide relative to each other, reducing the risk of jamming and breakage, and at the same time providing a damping feel for the folding of the second structural member 202 and the third structural member 203 relative to the second rotating mechanism 205. Figure 8 for Figure 6 A magnified view of the middle damping mechanism when the electronic device is in the second folded state.

[0082] Next, refer to Figure 8 When the protrusion 23 slides to the second preset position, the first end 231 of the protrusion 23 is located outside the groove 21. At this time, the protrusion 23 is decoupled from the main shaft 2001.

[0083] In some embodiments, when the first structural member 201 and the second structural member 202 are in a folded state, the protrusion 23 may be located outside the groove 21, and the second structural member 202 and the third structural member 203 may rotate smoothly relative to the second rotating mechanism 205.

[0084] To enable the protrusion 23 to slide along the accommodating space 22, in some embodiments, the folding mechanism further includes a moving member 24, which is disposed, for example, within the accommodating space 22. During the process of the first structural member 201 and the second structural member 202 folding relative to each other from the open state to the second folded state via the first rotating mechanism 204 when the second structural member 202 and the third structural member 203 are in the open state, the moving member 24 can move along the z-axis away from the second structural member 202, forming a clearance space within the accommodating space 22.

[0085] This application embodiment does not limit the connection method between the moving member 24 and the protrusion 23. In some embodiments, the movement direction of the moving member 24 is different from the movement direction of the protrusion 23, and the moving member 24 and the protrusion 23 are slidably connected. During the movement of the moving member 24 away from the second structural member 202, the moving member 24 drives the protrusion 23 to move, so that the second end 232 of the protrusion 23 enters the clearance space, and the first end 231 of the protrusion 23 moves away from the groove 21.

[0086] Example, Figure 9A This is a schematic diagram of a connection structure between a moving component and a protrusion, provided as an embodiment of this application. Figure 9A As shown, the protrusion 23 is provided with a first guide structure 230a and a third guide structure 230b, and the moving part 24 is provided with a second guide structure 240a and a fourth guide structure 240b. The second guide structure 240a corresponds to the first guide structure 230a, and the fourth guide structure 240b corresponds to the third guide structure 230b.

[0087] When the moving part 24 moves up and down along the z direction, the second guide structure 240a can drive the first guide structure 230a to slide along the x direction, and at the same time, the fourth guide structure 240b can drive the third guide structure 230b to slide along the x direction.

[0088] For example, when the moving component 24 moves upward along the z-axis, a clearance space is formed within the accommodating space 22. The second guide structure 240a can drive the first guide structure 230a to move along the x-axis in the -x direction, and the fourth guide structure 240b can drive the third guide structure 230b to move along the x-axis in the -x direction, causing the protrusion 23 to enter the clearance space. When the moving component 24 moves downward along the z-axis, the clearance space gradually decreases. The second guide structure 240 can drive the first guide structure 230 to move along the x-axis in the +x direction, and the fourth guide structure 240b can drive the third guide structure 230b to move along the x-axis in the +x direction, causing the protrusion 23 to exit the clearance space.

[0089] This application embodiment does not limit the types of the first guide structure 230a, the second guide structure 240a, the third guide structure 230b, and the fourth guide structure 240b. In some embodiments, such as Figure 9A As shown, the second guide structure 240a and the fourth guide structure 240b are guide rails, and the first guide structure 230a and the third guide structure 230b are guide blocks, which are slidably connected to the guide rails.

[0090] The embodiments of this application do not limit the number of guide structures. In some embodiments, the guide structures are a group. In this embodiment, the second guide structure 240a and the first guide structure 230a are a group, and the fourth guide structure 240b and the third guide structure 230b are a group. In other embodiments, there are two or more groups of guide structures.

[0091] In other embodiments, the moving member 24 and the protrusion 23 move in the same direction, and the moving member 24 is fixedly connected to the protrusion 23.

[0092] In other embodiments, the moving member 24 is not connected to the protrusion 23. When the first structural member 201 and the second structural member 202 are in the second folded state, and the second structural member 202 and the third structural member 203 are folded from the open state to the second folded state by the second rotating mechanism 205, the second rotating mechanism 205 pushes the second end 232 of the protrusion 23 to move in the x-direction and enter the clearance space, and the first end 231 of the protrusion 23 moves in the x-direction away from the groove 21.

[0093] To provide power to the moving part 24, a drive unit can also be provided. In some embodiments, the moving part 24 is not connected to the protrusion 23, or the moving part 24 is slidably connected to the protrusion 23, but the moving parts 24 and 23 move in different directions. For example, the moving part 24 can move along the z-axis, and the protrusion 23 can move along the x-axis. Figure 8 As shown, the driving part may include a first magnetic element 261 and a second magnetic element 262. The first magnetic element 261 is fixed to the first structural member, the second magnetic element 262 is located in the accommodating space, and the second magnetic element 262 is connected to the moving member 24. There is an attractive force between the first magnetic element 261 and the second magnetic element 262.

[0094] In this embodiment, an attractive force may exist between the first magnetic element 261 and the second magnetic element 262. That is, the magnetic poles of the ends of the first magnetic element 261 and the second magnetic element 262 near the first magnetic element 261 have opposite polarities. For example, if the end of the first magnetic element 261 near the second magnetic element 262 is the N pole, then the end of the second magnetic element 262 near the first magnetic element 261 is the S pole. Here, a magnetic element, also called a magnet, refers to a substance or material capable of generating a magnetic field. Magnetic elements can include permanent magnets and soft magnets. Permanent magnets can maintain their magnetism for a long time, are not easily demagnetized, and are not easily magnetized. For example, permanent magnets can include alloy permanent magnet materials and ferrite permanent magnet materials. Alloy permanent magnet materials can include alloys such as neodymium iron boron (Nd2Fe14B), samarium cobalt (SmCo), and alnico (AlNiCo). The polarity of a soft magnetic material changes with the polarity of the applied magnetic field, and it can be used as a magnetic conductor and electromagnet. For example, soft magnetic materials can include iron-silicon alloys (silicon steel sheets), soft magnetic ferrite materials, iron, cobalt, nickel, and alloys of iron, cobalt, and nickel. In this application, both the first magnetic element 261 and the second magnetic element 262 can be permanent magnets. Alternatively, one of the first magnetic element 261 or the second magnetic element 262 can be a permanent magnet, capable of maintaining magnetism for a long time, while the other can be a soft magnetic material that can be magnetized by the permanent magnet; this application does not limit this choice.

[0095] When the first structural member 201 and the second structural member 202 are in the open state, and the second structural member 202 and the third structural member 203 are in the open state, there is a gap between the first magnetic member 261 and the second magnetic member 262. During the process of the first structural member 201 and the second structural member 202 folding relative to each other from the open state to the second folded state via the first rotating mechanism 204, the second magnetic member 262, under the action of attraction, drives the moving member 24 to move along the z-axis towards the first structural member 201, forming a clearance space within the second structural member 202, into which the protrusion 23 can enter. Thus, the second structural member 202 and the third structural member 203 can rotate smoothly relative to the second rotating mechanism 205, thereby folding into... Figure 4 The third fold state is shown.

[0096] In other embodiments, when the moving member 24 and the protrusion 23 move in the same direction, for example, when both the moving member 24 and the protrusion 23 can move synchronously along the z-axis, the driving unit can be a motor. During the process of the first structural member 201 and the second structural member 202 moving from the open state to the second folded state through the first rotating mechanism 204, the motor can be activated by the user's operation of the trigger. The motor drives the moving member 24 to move along the x-axis, causing the protrusion 23 to move away from the groove 21 along the x-axis, forming a clearance space within the second structural member 202.

[0097] Furthermore, in order to enable the protrusion 23 and the moving part 24 to slide along a preset direction, such as Figure 9B As shown, a first guide portion 251 and a second guide portion 252 can also be provided, wherein the moving member 24 is slidably connected to the first guide portion 251, and the protrusion 23 is slidably connected to the second guide portion 252. Figure 9B This is a schematic diagram of the disassembled structure of a damping mechanism provided in an embodiment of this application.

[0098] This application embodiment does not limit the structure of the first guide portion 251 and the second guide portion 252. In some embodiments, such as Figure 9B As shown, the first guide portion 251 is a guide rod, and the second guide portion 252 is a guide groove. The moving member 24 has through holes (241a, 241b), and the guide rod passes through these through holes, allowing the moving member 24 to slide along the guide rod in the z-direction. The protrusion 23 is located within the guide groove, and the protrusion 23 can slide along the guide groove in the x-direction.

[0099] In other embodiments, the first guide portion 251 is a guide groove, and the second guide portion 252 is a guide rod. This application does not limit the type of the first guide portion 251 and the second guide portion 252. The structures of the first guide portion 251 and the second guide portion 252 described above are merely illustrative examples; they only need to be able to guide the protrusion 23 and the moving member 24, and all of these fall within the protection scope of this application.

[0100] This application embodiment does not limit the extending directions of the first guide portion 251 and the second guide portion 252. The extending directions of the first guide portion 251 and the second guide portion 252 determine the movement directions of the moving member 24 and the protrusion 23. In some embodiments, the extending directions of the first guide portion 251 and the second guide portion 252 may intersect. For example, the extending directions of the first guide portion 251 and the second guide portion 252 may be perpendicular; in this embodiment, the perpendicularity may have some error.

[0101] In some embodiments, the extending direction of the first guide portion 251 is perpendicular to the plane containing the second structural member 202. The extending direction of the second guide portion 252 is perpendicular to the extending direction of the first guide portion 251, and the extending direction of the second guide portion 252 is perpendicular to the axial direction of the second rotating mechanism.

[0102] The embodiments of this application do not limit the arrangement of the first guide portion 251 and the second guide portion 252. In some embodiments, reference is then made to... Figure 9B The folding mechanism also includes: a bracket 25, which is located at... Figure 7 Within the accommodating space 22 shown, the bracket 25 is connected to the second structural member 202.

[0103] The bracket 25 includes a base 250 and a fixing block 253. The first guide portion 251 includes a first guide rod 251a and a second guide rod 251b, and the second guide portion 252 includes a guide groove disposed within the fixing block 253.

[0104] The first guide rod 251a, the fixing block 253, and the second guide rod 251b are arranged side by side along the x-direction, with the fixing block 253 located between the first guide rod 251a and the second guide rod 251b. The extension direction of the guide rod is, for example, parallel to the z-direction, and the extension direction of the guide groove is parallel to the y-direction.

[0105] The moving component 24 includes a first through hole 241a and a second through hole 241b. A first guide rod 251a passes through the first through hole 241a and is slidably connected to it. A second guide rod 251b passes through the second through hole 241b and is slidably connected to it. Thus, the moving component 24 can slide up and down along the first guide rod 251a and the second guide rod 251b.

[0106] The shape of the moving member 24 is not limited in this embodiment. In some embodiments, the moving member 24 includes a snap-fit ​​portion, and the second magnetic member 262 snaps into the snap-fit ​​portion. When the second magnetic member 262 moves, the moving member 24 moves along the guide rod accordingly.

[0107] The embodiments of this application do not limit the number of damping mechanisms. In some embodiments, a folding mechanism includes one damping mechanism, which is disposed near the middle position of the second rotating mechanism.

[0108] In other embodiments, a folding mechanism includes two damping mechanisms, and the second rotating mechanism includes: a first end and a second end opposite to each other, the first end and the second end being disposed near the edge of the folding mechanism, one of the damping mechanisms being disposed near the first end of the second rotating mechanism, and the other damping mechanism being disposed near the second end of the second rotating mechanism.

[0109] In other embodiments, a folding structure includes multiple damping mechanisms, wherein there are three or more damping mechanisms, and the multiple damping mechanisms can be evenly arranged along the axial direction of the second rotating mechanism.

[0110] Figure 10 A simulation diagram of the torque during the folding process of the electronic device provided in this application embodiment from an open state to a first folded state. Wherein, Figure 10 The vertical axis represents torque in N·mm, and the horizontal axis represents the deformation of the bump in mm. For example... Figure 10As shown, the maximum torque during the folding process of the electronic device from the open state to the first folded state is 200 N·mm. Taking the electronic device with two sets of damping structures as an example, the damping mechanism can provide approximately 4 kgf·cm of torque, and there is no risk of parts jamming or breaking when forcibly bent.

[0111] Figure 11 This is a schematic diagram of the first engagement state of the damping mechanism during the folding process of the electronic device provided in this application embodiment to the first folded state. Figure 11 As shown, when the second and third structural components are folded relative to the second rotating mechanism to a first preset angle, the damping mechanism is in a first engaging state. In this first engaging state, the protrusion 23 is in contact with the main shaft 2001, providing resistance to the folding of the second and third structural components relative to the second rotating mechanism. Thus, when the user closes the third structural component first, the protrusion 23 provides resistance to the closing, increasing the user's feel and alerting the user that the closing sequence is incorrect.

[0112] Figure 12 This is a schematic diagram of the second engagement state of the damping mechanism during the folding process of the electronic device provided in this application embodiment to the first folded state. Figure 12 As shown, when the second structural component and the third structural component are folded relative to the second rotating mechanism to a second preset angle, the damping mechanism is in a second latching state. In this second latching state, the first end of the protrusion 23 slides downward relative to the main shaft 2001, and the second end of the protrusion tilts upward. The moving component 24 and the first magnetic component 261 tilt upward or move upward accordingly. The protrusion 23 can move towards the position of the moving component 24 to avoid jamming. Thus, when the user closes the third structural component in an incorrect folding sequence, the protrusion 23 can provide resistance to the closure, increasing the user's feel and reminding the user that the closure sequence is incorrect. Furthermore, during the process of the user closing in this incorrect sequence, the protrusion 23 and the main shaft 2001 can slide normally relative to each other without jamming or breakage, thus preventing damage to the electronic equipment. The second preset angle is smaller than the first preset angle.

[0113] The following is combined Figures 1-8 The working process of the folding mechanism is explained.

[0114] like Figure 1 As shown, when the first structural member 201 and the second structural member 202 are in the open state, and the second structural member 202 and the third structural member 203 are in the open state, as follows: Figure 7 As shown, there is a gap between the first magnetic component and the second magnetic component 262. The second magnetic component 262 and the moving component 24 are close to the bottom of the bracket 25. There is no clearance space in the accommodating space 22. The protrusion 23 extends out of the accommodating space 22. The first end 231 of the protrusion 23 is located in the groove 21 of the main shaft 2001.

[0115] In one instance, when the user closes the electronic device in the wrong order, for example, the first structural member 201 and the second structural member 202 are in the open state, and the second structural member 202 and the third structural member 203 are folded relative to each other from the open state via the second rotating mechanism 205. Figure 2 During the process of the first folding state shown, as Figure 7 As shown, there is a gap between the first magnetic component and the second magnetic component 262. The second magnetic component 262 and the moving component 24 are close to the bottom of the bracket 25. The first end 231 of the protrusion 23 rotates relative to the main shaft 2001 within the groove 21, providing resistance to the folding of the second structural component 202 and the third structural component 203 relative to the second rotating mechanism 205. Thus, when the user closes the third structural component 203 first, the protrusion 23 provides resistance to the closure, increasing the user's feel and reminding the user that the closure sequence is incorrect, preventing the user from further closing the first structural component 201 and reducing damage to the display screen.

[0116] Correspondingly, when the first structural member 201 and the second structural member 202 are in the open state, and the second structural member 202 and the third structural member 203 are in the open state, Figure 2 The first folded state shown is unfolded relative to the second rotating mechanism 205 to the following state: Figure 1 During the process of opening as shown, such as Figure 7 As shown, there is a gap between the first magnetic element and the second magnetic element 262. The second magnetic element 262 and the moving element 24 are close to the bottom of the bracket 25. The protrusion 23 rotates relative to the main shaft 2001 along the groove 21, providing resistance to the unfolding of the second structural element 202 and the third structural element 203 relative to the second rotating mechanism 205.

[0117] When the user closes the electronic device in the correct sequence, for example, when the second structural member 202 and the third structural member 203 are in the open state, the first structural member 201 and the second structural member 202 fold relative to each other from the open state via the first rotating mechanism 204. Figure 3 During the process of the second folding state shown, as Figure 8 As shown, the second magnetic component 262 drives the moving component 24 to move closer to the first structural component 201 under the action of the attraction, forming a clearance space in the second structural component 202, and the second end 232 of the protrusion 23 can enter the clearance space.

[0118] This application does not limit the manner in which the protrusion 23 enters the clearance space. In some embodiments, such as... Figure 9AAs shown, the protrusion 23 is coupled to the moving part 24. When the moving part 24 moves, it drives the protrusion 23 to move along the x-axis within the clearance space.

[0119] In other embodiments, such as Figure 9B As shown, the protrusion 23 is separated from the moving member 24, and the first structural member 201 and the second structural member 202 are in the following position. Figure 3 The second folded state shown indicates that the second structural member 202 and the third structural member 203 are folded relative to each other from the open state via the second rotating mechanism 205. Figure 4 During the process of the third folding state shown, as Figure 8 As shown, the second rotating mechanism 205 pushes the second end 232 of the protrusion 23 into the clearance space, and the second end 232 of the protrusion 23 moves away from the groove 21 along the x-axis. The second structural member 202 and the third structural member 203 can be smoothly closed or opened.

[0120] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope 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.
