Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronics, and particularly relates to a frame assembly and an electronic device. BACKGROUND

[0002] With the continuous development of electronic device technology, multi-functional terminal electronic products are increasingly favored by people. Electronic devices that can be opened and closed, such as notebook computers, folding mobile phones, and handheld game consoles, have the characteristics of thinness, convenience, and multi-functionality, and can be used in multiple scenarios such as entertainment and office work, and are increasingly favored by consumers.

[0003] Electronic devices that can be opened and closed usually include two housings that are rotationally coupled to meet the opening and closing requirements of the electronic device. For example, taking a notebook computer as an example, the electronic device can include a display end and a keyboard end, the display end can include a first housing, and the keyboard end can include a second housing. The first housing and the second housing can be rotationally coupled so that the display end and the keyboard end can be closed or unfolded to realize the opening and closing of the electronic device. Usually, the display end and the keyboard end are kept closed by the magnetic attraction of a magnet, and to achieve a large magnetic attraction effect, the volume and weight of the magnet are large, which is not conducive to the thin and light design of the electronic device. CONTENT OF THE UTILITY MODEL

[0004] The embodiments of the present application provide a frame assembly and an electronic device, which can ensure that the electronic device can be stably kept in a closed state, reduce the number, weight, and occupied space of the magnetic structure, and facilitate the thin and light design of the electronic device.

[0005] The first aspect of the embodiments of the present application provides a frame assembly for an electronic device that can be opened and closed, including two frame structures and a magnetic structure. The two frame structures are respectively used to surround one side of the two back covers of the electronic device, and the two frame structures are rotationally coupled to realize the opening and closing of the electronic device.

[0006] The magnetic structure is embedded on the two frame structures respectively. When the two frame structures are relatively rotated to make the electronic device in a closed state, the magnetic structures on the two frame structures are attracted, and the electronic device can be stably kept in the closed state.

[0007] When the electronic device is in the closed state, the distance between the two frame structures is relatively close, the distance between the magnetic structures embedded in the two frame structures is also relatively close, the distance between the magnetic structures in the two frame structures is narrowed, and there is part of the frame structure and a small gap between the two frame structures in the thickness direction. Compared with the related art in which the magnet is located in the display screen / face shell below the accommodating cavity, the magnetic structure is embedded in the frame structure, and there is no display screen, face shell, and distance to the display screen and face shell between the two magnetic structures, which further narrows the distance between the two magnetic structures and has higher magnetic force efficiency between the magnetic structures. Using a smaller number and smaller volume of magnetic structures can achieve approximately the same or better magnetic attraction, such as reducing the number and weight of the magnetic structures by about half or less, significantly reducing the weight of the frame assembly and the electronic device. Moreover, the space occupied by the magnet below the face shell and below the display screen can be saved, the space utilization is more efficient, the thickness space of the first shell and the second shell is reduced, the electronic device can be stably maintained in the closed state, and the light and thin design of the electronic device is realized.

[0008] In a possible implementation, each frame structure includes a first frame body, a second frame body and a third frame body connected in sequence, and the first frame body and the third frame body are located on both sides of the second frame body, and the frame structure is in the shape of a Chinese character.

[0009] In a possible implementation, the first frame body, the second frame body and the third frame body can each have a magnetic structure, and the magnetic structures on the three frame bodies in the two frame structures are attracted to each other, so that the electronic device is stably maintained in the closed state. The three frame bodies surrounding the frame structure each have a magnetic structure, which can achieve greater magnetic attraction, such as using a relatively small number and relatively low weight of magnetic structures to achieve greater magnetic attraction, which is beneficial to the light and thin design of the electronic device.

[0010] Moreover, the magnetic structures are distributed on the three frame bodies in a decentralized manner, and the large magnetic attraction between the magnetic structures can well maintain the first shell and the second shell in a relatively fixed state when the electronic device is in the closed state, and the electronic device is stably maintained in the closed state. The decentralized distribution of the magnetic structures also makes the distribution of the magnetic force relatively dispersed, and a relatively small force can be used to open the electronic device, which is more labor-saving and convenient for users to exert force, and is beneficial to improving the user experience.

[0011] In a possible implementation, the second frame body has a plurality of magnetic structures embedded therein, and the magnetic structures on the second frame bodies in the two frame structures are attracted to each other, so that the electronic device can be stably maintained in the closed state. Reducing the number and weight of the magnetic structure layout is more beneficial to the light and thin design of the electronic device.

[0012] In a possible implementation, the first frame and the third frame are respectively embedded with a plurality of magnetic structures. The magnetic structures on the two frames on the two sides are attracted to each other, so that the electronic device can be kept in a closed state more stably. The layout quantity and weight of the magnetic structures are relatively small, and the layout dispersion of the magnetic structures is relatively large, so that the electronic device is more labor-saving when being opened.

[0013] In a possible implementation, a groove is formed in the inner surface of the frame structure, and the magnetic structure is arranged in the groove, so that the magnetic structure is embedded in the frame structure, facilitating the embedding and assembly of the magnetic structure on the frame structure.

[0014] In a possible implementation, each magnetic structure includes a plurality of magnetic bodies arranged in sequence. That is, each magnetic structure is a magnetic body group composed of a plurality of magnetic bodies. Each magnetic structure includes a plurality of magnetic bodies, and the plurality of magnetic bodies can be arranged in a distributed manner. The magnetic force distribution of the magnetic structure is relatively dispersed. Compared with a magnetic structure including one magnetic body with a relatively large volume, the electronic device can be opened more labor-savingly, and the use experience is improved.

[0015] Moreover, the magnetic structure includes a plurality of magnetic bodies that can be arranged in a distributed manner. The layout position and quantity of the magnetic bodies have high design flexibility, and the magnetic bodies can be arranged on the frame structure flexibly. The position and quantity of the magnetic bodies can be designed flexibly according to the shape, size, strength and other requirements of the frame structure. The position and quantity of the magnetic bodies can also be designed flexibly in combination with the opening habit, hand feeling and experience requirements of the electronic device, so as to adjust and realize different hand feeling and opening requirements, meet various use scenarios, and improve the use experience.

[0016] In a possible implementation, the polarity directions of the plurality of magnetic bodies are the same. The polarity design of the magnetic bodies is relatively simple, and the implementation is facilitated.

[0017] Along the arrangement direction of the magnetic bodies, the length of the magnetic structure is less than or equal to 6 mm. When the length of the magnetic structure is relatively short, the plurality of magnetic bodies in the magnetic structure are arranged in the same polarity manner, and a relatively large magnetic force efficiency can be achieved.

[0018] In a possible implementation, the polarity directions of any adjacent magnetic bodies are opposite. When being assembled, the repulsive force between the two adjacent magnetic bodies in the same magnetic structure can be reduced, and the assembly is facilitated. Moreover, the magnetic attraction force between the two corresponding magnetic structures on the two frame structures can be further improved. Compared with the magnetic bodies arranged in the same polarity manner, the magnetic force efficiency can be improved by about 5% to 10%.

[0019] Along the arrangement direction of the magnetic bodies, the length of the magnetic structure is greater than or equal to 30 mm. When the length of the magnetic structure is relatively long, the plurality of magnetic bodies in the magnetic structure are arranged in the staggered polarity manner, and the magnetic structure can achieve a relatively large magnetic force efficiency.

[0020] In a possible implementation, the plurality of magnetic bodies form a Halbach array, so that the magnetic structure can function as a Halbach magnet, and the magnetic force efficiency can be improved by about 10% to 20% compared with the case where the magnetic bodies are arranged in the same polarity.

[0021] The length of the magnetic structure ranges from 6 mm to 15 mm along the arrangement direction of the magnetic bodies. When the length of the magnetic structure is the middle length, the plurality of magnetic bodies in the magnetic structure are arranged in the Halbach polarity, and the magnetic structure can achieve a relatively large magnetic force efficiency.

[0022] In a possible implementation, when the two frame structures are relatively rotated to the closed state of the electronic device, the distance between the magnetic structures on the two frame structures ranges from 0.55 mm to 1.55 mm. The distance between the magnetic structures is relatively small, and the magnetic force efficiency is relatively high, so that the electronic device can be kept in the closed state stably. Moreover, the number and weight of the magnetic structures can be reduced, and the thin and light design of the electronic device can be implemented.

[0023] In a possible implementation, when the two frame structures are relatively rotated to the closed state of the electronic device, the distance between the magnetic structures on the two frame structures is 1 mm. The high stability of the electronic device in the closed state is ensured, the thin design is facilitated, the influence of the magnetic structure on the strength of the frame structure can be reduced, and the electronic device has high strength and reliability.

[0024] In a possible implementation, in the magnetic structure of one of the frame structures, at least part of the magnetic bodies are soft magnetic bodies, and in the magnetic structure of the other frame structure, the magnetic bodies attracted to the soft magnetic bodies are hard magnetic bodies. The magnetic attraction between the two magnetic structures can be reduced, the magnetic force demand in a relatively small scene can be met, and the flexibility of the magnetic structure design is improved.

[0025] A second aspect of the present application provides an electronic device, including a display screen, two back covers, and the frame assembly of any one of the above, the two frame structures of the frame assembly are respectively arranged on one side of the two back covers, and the frame structure and the back cover form a containing cavity. At least one side of the frame structure away from the back cover is provided with a display screen. BRIEF DESCRIPTION OF DRAWINGS

[0066] Figure 1 A structural schematic diagram of an electronic device provided by the embodiments of the present application in an open state.

[0067] For example, in some examples, referring to Figure 1 As shown, taking a notebook computer as an example, the electronic device 100 can include a first housing 101 and a second housing 102, and the first housing 101 can be located on one side of the second housing 102.

[0068] Exemplarily, the electronic device 100 can include a display end and a keyboard end, and the keyboard end can include the first shell 101 and the key structure 104. The first shell 101 can serve as a main bearing structural member of the keyboard end.

[0069] Exemplarily, the first shell 101 can include a first back cover (not shown in the figure), a first bezel 101a located at one side of the first back cover, and a face cover 101b. The first bezel 101a and the first back cover enclose a first accommodating cavity, and the face cover 101b can be arranged on a side of the first bezel 101a away from the first back cover. The face cover 101b can cover an opening of the first accommodating cavity to enclose the first accommodating cavity.

[0070] For ease of description, in the embodiments of the present application, as shown in the figure, the thickness direction of the first shell 101 is shown as the z1 direction in the figure. Along the thickness direction, the face cover 101b and the first back cover can be located on two sides of the first bezel 101a, respectively. Figure 1

[0071] As shown in the figure, the width direction of the first shell 101 can be the x1 direction in the figure, and the length direction of the first shell 101 can be the y1 direction in the figure. The length direction, the width direction and the thickness direction can be perpendicular to each other. In the embodiments of the present application, the length, the width and the thickness are only for the convenience of description, and do not mean any limitation on the size. For example, the length can be greater than, equal to or less than the width. Figure 1

[0072] The first back cover and the first bezel 101a can be integrally formed, or in some examples, the first back cover and the first bezel 101a can be separately formed independent structural members, which can be connected and assembled together by means of bonding, threaded connection, clamping connection, welding, interference fit, etc.

[0073] The key structure 104 can be assembled to the first shell 101. For example, the key structure 104 can be arranged on the face cover 101b, and at least part of the key structure 104 can be located in the first accommodating cavity. The key structure 104 can be used to identify the operation information of the user, and can also realize the human-computer interaction with the user, etc.

[0074] It should be understood that the key structure 104 can be a convex mechanical button structure, or the key structure 104 can also be a virtual key, etc.

[0075] The display end can include a second shell 102 and a display screen 105. The second shell 102 can serve as a main bearing structural member of the display end. The display screen 105 can be used to display images, etc., and can also be used to identify the operation information of the user, such as the operation position information, gesture information, etc. of the user, to realize the human-computer interaction with the user, etc.​​

[0076] For example, the second housing 102 can include a second back cover 102b (see Figure 2 ) and a second frame 102a (see Figure 1 ), the second frame 102a is located at one side of the second back cover 102b, and the second frame 102a and the second back cover 102b enclose a second accommodating cavity. The display screen 105 can be arranged on the side of the second frame 102a away from the second back cover 102b, and the display screen 105 can cover the opening of the second accommodating cavity to seal the second accommodating cavity.

[0077] The thickness direction of the second housing 102 is the z2 direction (see Figure 2 ), it can be understood that when the electronic device 100 is in the closed state as shown in Figure 2 , the thickness direction z2, the length direction y2 and the width direction x2 of the second housing 102 can be consistent with the thickness direction, the length direction and the width direction of the first housing 101 respectively. Along the thickness direction, the second back cover 102b and the display screen 105 can be located on both sides of the second frame 102a.

[0078] The display screen 105 and the second back cover 102b can be located on opposite sides of the second frame 102a, and the second frame 102a can be arranged around the display screen 105 to play a role of edge protection for the display screen 105. The side of the display screen 105 away from the second back cover 102b (the second accommodating cavity) can be a display surface, and in some examples, part of the second frame 102a can extend onto the display surface of the display screen 105.

[0079] The second back cover 102b and the second frame 102a can be integrally formed, or in some examples, the second back cover 102b and the second frame 102a can be separately formed independent structural members, which can be connected and assembled together by bonding, threaded connection, clamping connection, welding, interference fit, etc.

[0080] In the embodiments of the present application, the type of the display screen 105 is not limited, for example, the display screen 105 can be an organic light-emitting diode (OLED) display screen, a micro organic light-emitting diode display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a light emitting diode (LED) display screen, a mini organic light-emitting diode (Mini LED) display screen, a micro organic light-emitting diode (Micro LED) display screen, a quantum dot light emitting diode (QLED) display screen, a liquid crystal display (LCD), and the like.

[0081] It should be noted that the keyboard end and the display end can also include other functional modules to ensure the integrity of the functions of the electronic device 100, for example, the first accommodating cavity of the keyboard end can also be provided with a main control circuit board, a charging and discharging system, a heat sink, a microphone, a loudspeaker and the like, and the second accommodating cavity of the display end can also be provided with a camera module and the like.

[0082] Continuing to refer to Figure 1 As shown, the electronic device 100 can also include an opening and closing mechanism 103, the first shell 101 and the second shell 102 can be located on the two sides of the opening and closing mechanism 103, and the opening and closing mechanism 103 is connected with the first shell 101 and the second shell 102 respectively, and the first shell 101 and the second shell 102 can be rotationally matched by the opening and closing mechanism 103, so that the display end and the system end of the electronic device 100 can be relatively rotated to realize the opening and closing of the electronic device 100.

[0083] As shown in Figure 1 The first shell 101 and the second shell 102 can be relatively unfolded to an open state, and the first shell 101 and the second shell 102 cannot be continuously rotated when being unfolded, at this time, the electronic device 100 is in an open state, which can also be called an unfolded state.

[0084] Exemplarily, when the electronic device 100 is in the open state, the second housing 102 can be opened at a certain angle relative to the first housing 101, and the angle between the first housing 101 and the second housing 102 can be selected and set according to actual design requirements. For example, when the electronic device 100 is in the open state, the angle a between the first housing 101 and the second housing 102 is approximately 135°, or in some examples, the angle between the first housing 101 and the second housing 102 can also be about 120°, 140°, 150°, 160°, 170°, 180°, etc.

[0085] Figure 2 For Figure 1 The structural schematic diagram of the electronic device in the closed state.

[0086] Referring to Figure 2 As shown, the first housing 101 and the second housing 102 can be folded to the closed state, and when the first housing 101 and the second housing 102 are in the closed state, they can be completely folded to be parallel to each other (allowing a small deviation), and the included angle between the first housing 101 and the second housing 102 can be approximately 0°, at this time, the electronic device 100 is in the closed state, also called the folded state. The electronic device 100 can be in the form of being folded into two layers, and the first housing 101 and the second housing 102 can have a narrow gap therebetween.

[0087] The first housing 101 and the second housing 102 can also be relatively rotated (folded or opened) to an intermediate state, so that the electronic device 100 is in the intermediate state. Exemplarily, taking the angle between the first housing 101 and the second housing 102 as approximately 135° when the electronic device 100 is in the open state as an example, when the electronic device 100 is in the intermediate state, the included angle between the first housing 101 and the second housing 102 can be greater than 0° and less than 135°.

[0088] It can be understood that the intermediate state can be any state between the open state and the closed state, that is, the electronic device 100 can be switched between the open state and the closed state through the movement of the opening and closing mechanism 103, and the electronic device 100 can have multiple intermediate states.

[0089] In some examples, the electronic device 100 can also be a folding phone, which can be a foldable phone with an in-display folding screen, or the folding phone can also be a foldable phone with an out-display folding screen. Alternatively, the folding phone can be a foldable phone with an in-display folding screen and an additional out-display folding screen, or the folding phone can also be a foldable phone with a partial in-display folding screen and a partial out-display folding screen.

[0090] Figure 3Another structure schematic diagram of the electronic device provided by the embodiment of the present application in an open state.

[0091] Taking the electronic device 100 as an example of a foldable mobile phone with a display screen inside folding, referring to FIG. 1, the electronic device 100 includes a first housing 101, an opening and closing mechanism 103, and a second housing 102. The first housing 101 and the second housing 102 are respectively located on two sides of the opening and closing mechanism 103, and the first housing 101 and the second housing 102 can be respectively connected with the opening and closing mechanism 103, so that the first housing 101 and the second housing 102 are rotationally matched through the opening and closing mechanism 103. The first housing 101 and the second housing 102 can be relatively rotated to realize the opening and closing of the electronic device 100. Figure 3 The electronic device 100 further includes a flexible display screen 106, wherein the display screen 106 is laid on the opening and closing mechanism 103, the first housing 101, and the second housing 102. Specifically, the display screen 106 is located on the same side surface of the first housing 101, the second housing 102, and the opening and closing mechanism 103. For the electronic device 100 with the display screen inside folding, the display screen 106 is arranged on the inner side surface of the first housing 101, the second housing 102, and the opening and closing mechanism 103. For the foldable electronic device 100 with the display screen outside folding, the display screen 106 is arranged on the outer side surface of the first housing 101, the second housing 102, and the opening and closing mechanism 103.

[0092] For example, the first housing 101 can include a first back cover 101c (refer to FIG. 1) and a first bezel 101a. The first bezel 101a is located on one side of the first back cover 101c, and the first bezel 101a and the first back cover 101c enclose a first accommodating cavity. The second housing 102 can include a second back cover (not shown in the figure) and a second bezel 102a. The second bezel 102a is located on one side of the second back cover, and the second bezel 102a and the second back cover enclose a second accommodating cavity.

[0093] Figure 4 Part of the display screen 106 can be located on the side of the first bezel 101a away from the first back cover 101c, and part of the display screen 106 can be located on the side of the second bezel 102a away from the second back cover. The display screen 106 can cover the openings of the first accommodating cavity and the second accommodating cavity to enclose the first accommodating cavity and the second accommodating cavity.

[0094] When the electronic device 100 is in an open state (refer to FIG. 1), part of the display screen 106 and the first back cover 101c can be respectively located on two sides of the first bezel 101a in the thickness direction, and part of the display screen 106 and the second back cover can be respectively located on two sides of the second bezel 102a in the thickness direction. Figure 3

[0095] ​​The first back cover 101c and the first frame 101a can be integrally formed, or the first back cover 101c and the first frame 101a can be separately formed and then connected and assembled together. The second back cover and the second frame 102a can be integrally formed, or the second back cover and the second frame 102a can be separately formed and then connected and assembled together. The assembly method is described above and will not be repeated here.

[0096] In this embodiment of the application, the type of display screen 106 is not limited. Examples of the type of display screen 106 can be found above, and will not be repeated here.

[0097] The electronic device 100 may also include other structural components to ensure the integrity of its functions. For example, the electronic device 100 may also include a main control circuit board, a charging and discharging system, a heat sink, a microphone, a speaker, a camera, and other structural components. The aforementioned structural components may be disposed within the first receiving cavity and / or the second receiving cavity.

[0098] For example, such as Figure 3 As shown, the first housing 101 and the second housing 102 can be unfolded relative to each other into an open state. The first housing 101 and the second housing 102 are unfolded until they can no longer rotate; at this point, the electronic device 100 is in an open state, also referred to as an unfolded state. For example, when the first housing 101 and the second housing 102 are in the open state, they can be approximately 180° apart (a slight deviation is permissible). The display screen 106 can be unfolded and laid flat on one side of the first housing 101, the second housing 102, and the opening / closing mechanism 103.

[0099] Figure 4 for Figure 3 A schematic diagram of the structure of an electronic device in a closed state.

[0100] See Figure 4 As shown, the first housing 101 and the second housing 102 can be folded relative to each other to a closed state, and the display screen 106 also bends accordingly (not shown in the figure). For example, when the first housing 101 and the second housing 102 are in a closed state, they can be completely closed to be parallel to each other (allowing for slight deviations). At this time, the electronic device 100 is in a closed state, also known as a folded state. Part of the display screen 106 is attached to the first housing 101, and part of the display screen 106 is attached to the second housing 102. The part of the display screen 106 opposite to the opening and closing mechanism 103 is bent and located within the screen-accommodating space enclosed by the opening and closing mechanism 103.

[0101] The first shell 101 and the second shell 102 can also be relatively rotatable (foldable or unfoldable) to an intermediate state, so that the electronic device 100 is in the intermediate state, and the display screen 106 opposite the opening mechanism can be folded or unfolded. The intermediate state can be any state between the open state and the closed state.

[0103] To ensure that the electronic device can be stably kept in the closed state, the electronic device is usually kept closed by magnetic attraction. For example, as shown in FIGS. 1 and 2, the electronic device 200 is taken as a notebook computer, and a first magnet 2011 can be arranged in the first shell 201. The first magnet 2011 is located in a first accommodating cavity of the first shell 201 and is located below the face shell 2012 (the side away from the second shell 202) along the thickness direction (z1 direction in FIG. 1) of the first shell 201. Figure 5 Figure 6 A second magnet 2021 can be arranged in the second shell 202. The second magnet 2021 is located in a second accommodating cavity of the second shell 202 and is located below the display screen 203 (the side away from the first shell 201) along the thickness direction (z2 direction in FIG. 2) of the second shell 202. Figure 6 Figure 6 FIG. 4 is a schematic diagram of an electronic device in a closed state according to the related art,

[0104] FIG. 5 is a partial enlarged schematic diagram of an electronic device in a closed state according to the related art. In the figure, Figure 7 FIG. 6 is a schematic diagram of an electronic device in a closed state, viewed along the width direction (x1 direction in FIG. 5) of the first shell (the second shell). Figure 5 Figure 8 FIG. 7 is a schematic diagram of an electronic device in a closed state, viewed along the width direction (x1 direction in FIG. 5) of the first shell (the second shell). Figure 8 Figure 7 FIG. 8 is a schematic diagram of an electronic device in a closed state, viewed along the width direction (x1 direction in FIG. 5) of the first shell (the second shell).

[0105] FIG. 9 is a schematic diagram of an electronic device in a closed state, viewed along the width direction (x1 direction in FIG. 5) of the first shell (the second shell). Figure 7 Figure 8 ​​​​As shown, when the electronic device 200 is in the closed state, the first magnet 2011 and the second magnet 2021 are attracted to each other, so that the first shell 201 and the second shell 202 can be kept relatively fixed, and the electronic device 200 can be stably kept in the closed state. When the electronic device 200 is switched from the closed state to the intermediate state or the open state, an external force is applied to the first shell 201 and the second shell 202, and the external force is greater than the attractive force between the first magnet 2011 and the second magnet 2021, so that the first shell 201 and the second shell 202 can be relatively rotated, and the electronic device 200 can be opened.

[0106] The first magnet 2011 in the first accommodating cavity and the second magnet 2021 in the second accommodating cavity are attracted to each other, and along the thickness direction (such as the z1 direction in FIG. 1A), at least part of the display screen 203 and part of the face cover 2012 will exist between the first magnet 2011 and the second magnet 2021, for example, in the example in which the second bezel 2023 of the second shell 202 extends to the display screen 203, part of the second bezel 2023 (and / or the first bezel 2014) will also exist between the first magnet 2011 and the second magnet 2021, and the distance between the first magnet 2011 and the second magnet 2021 is relatively far. Figure 7 Figure 7 As shown, the first magnet 2011 in the first accommodating cavity is generally fixed on the first rear cover 2013 of the first shell 201 and has a certain distance from the face cover 2012. The second magnet 2021 in the second accommodating cavity is generally fixed on the second rear cover 2022 of the second shell 202 and has a certain distance from the display screen 203. When the electronic device 200 is in the closed state, there will also be a small gap between the first shell 201 and the second shell 202. The existence of these distances will also increase the distance between the first magnet 2011 and the second magnet 2021 when the electronic device 200 is in the closed state, and affect the magnetic force efficiency between the first magnet 2011 and the second magnet 2021. For example, as shown in FIG. 1A, when the electronic device 200 is in the closed state, the distance d1 between the first magnet 2011 and the second magnet 2021 along the thickness direction (such as the z1 direction) is about 2.7mm-3mm, and the distance is relatively large, so that the magnetic force efficiency between the first magnet 2011 and the second magnet 2021 is relatively low. Figure 8

[0107] In order to meet the attraction force requirement between the first magnet and the second magnet when the electronic device is in the closed state, the volume of the first magnet and the second magnet is relatively large, the space occupied in the thickness direction is relatively large, and the weight is relatively heavy. For example, the weight of the first magnet and the second magnet is about 13g, which greatly affects the thickness and weight of the electronic device, and is not conducive to the lightweight design of the electronic device.

[0108] ​​Based on this, the embodiment of the present application provides a frame assembly. By comprising two frame structures and a magnetic structure, the magnetic structure is embedded on the two frame structures respectively. When the two frame structures are relatively rotated to make the electronic device in a closed state, the magnetic structures on the two frame structures are attracted to each other, so that the electronic device can be stably kept in the closed state. The distance between the two frame structures is relatively close in the closed state, and the distance between the magnetic structures embedded in the two frame structures is also relatively close, which shortens the distance between the magnetic structures. In the thickness direction, there is part of the frame structure and a small gap between the two frame structures. Compared with the related art in which the magnet is located in the display screen / face shell below the accommodating cavity, there is no display screen, face shell, and distance to the display screen and face shell between the two magnetic structures, which further effectively shortens the distance between the two magnetic structures, and the magnetic structure has higher magnetic force efficiency. Using a smaller number and smaller volume of magnetic structures can achieve approximately the same or better magnetic attraction force. For example, the number and weight of the magnetic structure can be reduced by about half or less, which significantly reduces the weight of the frame assembly and the electronic device. Moreover, the space occupied by the magnet below the face shell and below the display screen can be saved, the space utilization is more efficient, which is beneficial to reduce the thickness space of the first shell and the second shell, ensures that the electronic device can be stably kept in the closed state, and is beneficial to realize the lightweight design of the electronic device.

[0109] Figure 9 A partial structure schematic diagram of an electronic device in an open state is provided in the embodiment of the present application.

[0110] Referring to Figure 9 As shown in the figure, the frame assembly 107 comprises two frame structures 10. For example, the two frame structures 10 can be respectively used as the first frame 101a and the second frame 102a of the electronic device 100 described above. The two frame structures 10 are rotationally matched, so that the first shell 101 and the second shell 102 of the electronic device 100 can be rotationally matched to realize the opening and closing of the electronic device 100.

[0111] For example, the two frame structures 10 can be rotationally matched by an opening and closing mechanism (not shown in the figure), and the opening and closing mechanism can be located between the two frame structures 10, such as the position shown by the dashed line in the figure.

[0112] Taking the electronic device 100 in Figure 9 as an example of the notebook computer described above, the first frame 101a can be arranged around one side of the first rear cover (not shown in the figure) to form a first accommodating cavity. The face shell 101b can be arranged on the side of the first frame 101a away from the first rear cover, and the first frame 101a can also be arranged around the face shell 101b.

[0113] In some examples, the face cover 101b can be flush with an end surface of the first bezel 101a facing away from the first back cover in the thickness direction. Alternatively, the face cover 101b can protrude from the end surface of the first bezel 101a facing away from the first back cover. Alternatively, in some examples, part of the first bezel 101a can be located on a surface of the face cover 101b facing away from the first accommodating cavity, covering part of the circumferential edge of the face cover 101b.

[0114] The second bezel 102a can surround a side of the second back cover (not shown in the figure) to enclose a second accommodating cavity, and the display screen 105 can be arranged on a side of the second bezel 102a facing away from the second back cover, and the second bezel 102a can also surround the display screen 105.

[0115] In the example of the folding mobile phone described above, the first bezel 101a can surround a side of the first back cover (not shown in the figure) to enclose a first accommodating cavity, and part of the flexible display screen can be arranged on a side of the first bezel 101a facing away from the first back cover (for example, refer to the position of the display screen 105 in Figure 9 , and the first bezel 101a can surround the part of the flexible display screen.

[0116] The second bezel 102a can surround a side of the second back cover (not shown in the figure) to enclose a second accommodating cavity, and part of the flexible display screen can be arranged on a side of the second bezel 102a facing away from the second back cover (for example, refer to the position of the face cover 101b in Figure 9 , and the second bezel 102a can surround the part of the flexible display screen.

[0117] The bezel assembly 107 further comprises a magnetic structure 20 embedded on each of the two bezel structures 10. For example, the magnetic structure 20 can comprise a first magnetic structure 20a and a second magnetic structure 20b, the first magnetic structure 20a can be embedded on the first bezel 101a, and the second magnetic structure 20b can be embedded on the second bezel 102a.

[0118] It should be noted that the number of magnetic structures 20 embedded on each bezel structure 10 is not limited, and one magnetic structure 20 can be embedded on each bezel structure 10, or a plurality of magnetic structures 20 can be embedded on each bezel structure 10.

[0119] When the electronic device 100 is in the open state, taking the angle between the first shell 101 and the second shell 102 of the electronic device 100 as about 180° for example, as shown in Figure 9 , the angle between the first bezel 101a and the second bezel 102a is also about 180°.

[0120] Figure 10 For Figure 9A partial structural schematic diagram of the electronic device in the intermediate state.

[0121] The first frame 101a and the second frame 102a are relatively rotatable, so that the first housing 101 and the second housing 102 can be relatively rotated to the electronic device 100 in the intermediate state, as shown in Figure 10 As shown in the middle, the angle between the first frame 101a and the second frame 102a can be less than 180°.

[0122] Figure 11 For Figure 9 A partial structural schematic diagram of the electronic device in the folded state, Figure 12 An enlarged partial structural schematic diagram of the electronic device in the closed state provided by another embodiment of the present application. Among them, Figure 12 A schematic diagram of the electronic device 100 in the closed state, viewed from the width direction of the first housing 101 (or the second housing 102), such as Figure 9 The x1 direction in the middle).

[0123] As shown in Figure 11 The first frame 101a and the second frame 102a can be relatively rotated and folded, so that the first housing 101 and the second housing 102 can be relatively folded to the electronic device 100 in the closed state. The first magnetic structure 20a on the first frame 101a and the second magnetic structure 20b on the second frame 102a are attracted to each other, and the magnetic attraction force between the first magnetic structure 20a and the second magnetic structure 20b enables the first housing 101 and the second housing 102 to be relatively fixed, thereby enabling the electronic device 100 to be stably maintained in the closed state.

[0124] When an external force is applied to the first frame 101a (the first housing 101) and the second frame 102a (the second housing 102), when the external force is greater than the magnetic attraction force between the first magnetic structure 20a and the second magnetic structure 20b, the first frame 101a and the second frame 102a can be relatively rotated, so that the electronic device 100 switches to the intermediate state or the open state.

[0125] In combination with Figure 11 And Figure 12As shown, when the electronic device 100 is in the closed state, the distance between the two frame structures 10 is relatively close, the distance between the magnetic structures 20 embedded in the two frame structures 10 is also relatively close, and the distance between the first magnetic structure 20a and the second magnetic structure 20b is narrowed. In the thickness direction (such as z1 direction), there is part of the frame structure 10 and a small gap between the two frame structures 10 between the first magnetic structure 20a and the second magnetic structure 20b. Compared with the prior art in which the first magnet is located in the first accommodating cavity and below the face cover, and the second magnet is located in the second accommodating cavity and below the display screen, the magnetic structure 20 is embedded in the frame structure 10, and there can be no display screen 105, face cover 101b, and spacing to the display screen 105 and face cover 101b between the two magnetic structures 20, further narrowing the distance between the two magnetic structures 20.

[0126] Figure 13 The curve diagram of the relationship between the distance between the two magnetic structures and the magnetic force efficiency.

[0127] Referring to Figure 13 As shown, the magnetic force efficiency between the two magnetic structures and the distance between the magnetic structures are inversely proportional to the square of the distance, for example, the magnetic force efficiency and the distance between the magnetic structures can satisfy the condition formula:

[0128]

[0129] Wherein, z can be the vertical straight distance between the two magnetic structures, F0 can be the vertical attraction between the two magnetic structures when the vertical straight distance z = 0, d e may be the equivalent 1 / 4F0 distance, F z (x = 0, z = de) = 1 / 4F0.

[0130] Narrowing the distance between the two magnetic structures can improve the magnetic force efficiency, in the embodiment of the present application, continue to combine Figure 11 and Figure 12As shown, the magnetic structure 20 is embedded in the frame structure 10, effectively reducing the distance between the magnetic structures 20 in the frame structure 10, and the magnetic structures 20 have higher magnetic force efficiency. Using a smaller number and smaller volume of magnetic structures 20 can achieve approximately the same or better magnetic attraction force. For example, compared with the magnet arrangement scheme in the related art, the number and weight of the magnetic structures 20 in the embodiment of the present application can be reduced by about 50% or less, significantly reducing the weight of the frame assembly 107 and the electronic device 100. Moreover, the space occupied by the magnets arranged below the face cover 101b and below the display screen 105 can be saved, space utilization is more efficient, which is beneficial to reduce the thickness of the first shell 101 and the second shell 102, and ensure that the electronic device 100 can be very stably maintained in the closed state, which is beneficial to realize the lightweight design of the electronic device 100.

[0131] For example, when the electronic device 100 is in the closed state, referring to Figure 12 As shown, along the thickness direction (such as z1 direction), the distance d2 between the first magnetic structure 20a and the second magnetic structure 20b can be 0.55mm-1.55mm, the distance between the first magnetic structure 20a and the second magnetic structure 20b is small, and the first magnetic structure 20a and the second magnetic structure 20b have high magnetic force efficiency, so that the electronic device 100 can be stably maintained in the closed state. Moreover, the number and weight of the magnetic structures 20 can be better reduced, which is more beneficial to realize the lightweight design of the electronic device 100.

[0132] For example, when the electronic device 100 is in the closed state, along the thickness direction (such as z1 direction), the distance d2 between the first magnetic structure 20a and the second magnetic structure 20b can be about 1mm, which ensures the high stability of the electronic device 100 in the closed state, is beneficial to thin design, and can reduce the influence of the arrangement of the magnetic structure 20 on the strength of the frame structure 10, and ensures that the electronic device 100 has high strength and reliability.

[0133] For example, when the electronic device 100 is in the closed state, along the thickness direction (such as z1 direction), the distance d2 between the first magnetic structure 20a and the second magnetic structure 20b can be about 1mm, which ensures the high stability of the electronic device 100 in the closed state, is beneficial to thin design, and can reduce the influence of the arrangement of the magnetic structure 20 on the strength of the frame structure 10, and ensures that the electronic device 100 has high strength and reliability.

[0134] It should be noted that when the electronic device 100 is in the closed state, the magnetic structures 20 in the two frame structures 10 are attracted to each other, the positions of the magnetic structures 20 in the two frame structures 10 can correspond to each other, and the polar directions of the two magnetic structures 20 can be approximately consistent. For example, in the thickness direction (for example, the z1 direction), the vertical projections of the two magnetic structures 20 at least partially overlap, so as to ensure that the two magnetic structures 20 have a good magnetic attraction force.

[0135] For example, as shown in FIG. 1A, the vertical projections of the first magnetic structure 20a and the second magnetic structure 20b can completely overlap, which is beneficial to improving the magnetic attraction force between the first magnetic structure 20a and the second magnetic structure 20b. Figure 12

[0136] In some examples, each frame structure 10 can have opposite outer surfaces and inner surfaces, where the outer surfaces can serve as appearance surfaces, and the inner surfaces can be the surfaces of the frame structure 10 facing the first accommodating space or the second accommodating space. The magnetic structure 20 can be embedded on the inner surface of each frame structure 10. By embedding the magnetic structure 20 on the inner surface of the frame structure 10, the distance between the magnetic structures 20 in the two frame structures 10 can be shortened under the condition of ensuring the appearance aesthetics of the frame structure 10.

[0137] Figure 14 FIG. 2 shows a front structure diagram of one of the frame structures in a frame assembly according to an embodiment of the present application, Figure 15 FIG. 3 shows a front structure diagram of one of the frame structures in a frame assembly according to an embodiment of the present application, Figure 14 FIG. 4 shows a back structure diagram of one of the frame structures in a frame assembly according to an embodiment of the present application.

[0138] For example, as shown in FIG. 2, the first frame 101a can have opposite first outer surfaces 10c and first inner surfaces 10a in the thickness direction (for example, the z1 direction). Figure 14 Figure 15 For example, as shown in FIG. 2, the first frame 101a can have opposite first outer surfaces 10c and first inner surfaces 10a in the thickness direction (for example, the z1 direction).

[0139] The first inner surface 10a can face away from the second frame 102a, and the first inner surface 10a can be farther away from the second frame 102a. The first inner surface 10a can face the first accommodating cavity in the first housing. When the electronic device 100 is in the open state, the first outer surface 10c can be the appearance surface of the first frame 101a.

[0140] For example, as shown in FIG. 2, the first magnetic structure 20a can be embedded on the first inner surface 10a of the first frame 101a, so as to ensure the aesthetics of the first outer surface. Figure 15

[0141] ​​​In some examples, the first frame 101a can include a first frame body 11 and a first extension 12, one side of the first extension 12 can form a first outer surface of the first frame 101a, the first frame body 11 can be arranged around the side of the first extension 12 facing away from the first outer surface, and the first frame body 11 can be arranged protruding from the first extension 12, so that the first frame body 11 and the first extension 12 can form a stepped structure on the side of the first inner surface 10a of the first frame 101a.

[0142] The first magnetic structure 20a can be embedded on the first frame body 11. For example, the edge of the face cover can be arranged on the side of the first extension 12 facing away from the first outer surface, so that part of the first frame 101a is arranged around the face cover.

[0143] In some examples, a groove 15 can be formed on the inner surface of the frame structure 10, for example, a groove 15 is formed on the first frame body 11, and the magnetic structure 20 can be arranged in the groove 15, so that the magnetic structure 20 is embedded on the frame structure 10, facilitating the embedding and assembly of the magnetic structure 20 on the frame structure 10.

[0144] It should be noted that the magnetic structure 20 can include one or more magnetic bodies 211 (see Figure 16 ), and the number of grooves 15 can correspond to the number of magnetic bodies 211. In the embodiments of the present application, the shape and size of the groove 15 are not limited, and the shape and size of the groove 15 can be matched with the shape and size of the magnetic body 211. The size of the groove 15 can be greater than or equal to the size of the magnetic body 211.

[0145] Figure 16 For Figure 15 the split structure of the middle frame assembly.

[0146] For example, taking the first frame 101a as an example, referring to Figure 16 , a groove 15 can be formed on the first inner surface 10a of the first frame 101a, and the first magnetic structure 20a can be arranged in the groove 15.

[0147] For example, the opening of the groove 15 can be located on the inner surface of the frame structure 10, the magnetic structure 20 can be arranged in the groove 15 by adhesion, clamping, interference fit, etc., at least part of the magnetic structure 20 can be exposed on the side of the inner surface of the frame structure 10, and the magnetic structure 20 is semi-openly arranged, facilitating assembly and reducing cost. For example, as shown in the first magnetic structure 20a in Figure 16 , the opening of the groove 15 is located on the first inner surface 10a of the first frame 101a, and the first magnetic structure 20a is semi-openly arranged and exposed on the side of the first inner surface 10a of the first frame 101a.

[0148] Among them, the magnetic structure 20 can partially protrude outside the groove 15, or the magnetic structure 20 can be entirely located inside the groove 15, and a part of the magnetic structure 20 is exposed through the opening of the groove 15.

[0149] Alternatively, injection molding or other methods can be used to form an injection molding structure on the inner surface of the frame structure 10, so that the injection molding structure can cover the part of the magnetic structure 20 protruding outside the groove 15 or cover the opening of the groove 15 and the magnetic structure 20 inside the groove 15. In this way, the magnetic structure 20 is enclosed inside the frame structure 10 and the injection molding structure, and the magnetic structure 20 can be not exposed and invisible, making the magnetic structure 20 have higher assembly stability and can play an isolation and protection role for the magnetic structure 20.

[0150] Exemplarily, the structural shapes of the two frame structures 10 of the electronic device can match. For example, each frame structure 10 can include a first frame body, a second frame body, and a third frame body connected in sequence. The first frame body and the third frame body can be respectively located on both sides of the second frame body, making the frame structure 10 in a shape similar to a C shape.

[0151] For example, as shown in Figure 14 to Figure 16 Taking the first frame 101a as an example, the first frame 101a can include a first frame body 110, a second frame body 120, and a third frame body 130 connected in sequence. The first frame body 110 and the third frame body 130 are respectively located on both sides of the second frame body 120, making the frame structure 10 enclose a structure similar to a C shape.

[0152] One end of the first frame body 110 and one end of the third frame body 130 can be respectively connected to both ends of the second frame body 120. The other end of the first frame body 110 and the other end of the third frame body 130 can be arranged adjacent to the opening and closing mechanism of the electronic device. The space between the other end of the first frame body 110 and the other end of the third frame body 130 can facilitate the connection and cooperation between other structural components of the electronic device and the opening and closing mechanism. The second frame body 120 is opposite to the opening and closing mechanism 103, and the second frame body 120 can be arranged farther away from the opening and closing mechanism.

[0153] The first frame body, the second frame body, and the third frame body of the two frame structures 10 respectively correspond to each other. For example, when the electronic device is in a closed state, in the thickness direction, the first frame body of the first frame 101a and the first frame body of the second frame 102a correspond to each other, that is, in the thickness direction, the vertical projections of the two first frame bodies can overlap (partially or entirely). The second frame body of the first frame 101a and the second frame body of the second frame 102a correspond to each other, that is, in the thickness direction, the vertical projections of the two second frame bodies can overlap (partially or entirely). The third frame body of the first frame 101a and the third frame body of the second frame 102a correspond to each other, that is, in the thickness direction, the vertical projections of the two third frame bodies can overlap (partially or entirely).

[0154] In the embodiments of the present application, the layout of the magnetic structure 20 on the three frame structures of the frame structure 10 is not limited, and the magnetic structure 20 can be arranged on all the three frame structures, or the magnetic structure 20 can be arranged on only part of the frame structures. For example, the layout can be selected and set according to the shape, structure, size and strength of the frame structure. The layout can also be set in combination with habits, hand feeling, experience and other needs when the electronic device is opened, so as to meet different habits and hand feeling experience needs of the user and improve the use experience. For example, in some examples, the user is used to opening the electronic device from two sides (the first frame side and / or the third frame side) of the electronic device, and in order to strengthen the hand feeling, the magnetic structure 20 can be arranged on the first frame and the third frame.

[0155] In some examples, the magnetic structure 20 can be arranged on the first frame, the second frame and the third frame, and the magnetic structures 20 on the three frame structures of the two frame structures 10 are attracted to each other, so that the electronic device is stably kept in the closed state. For example, in combination with the structures shown in Figure 15 and Figure 16 As shown in FIGS. 1 and 2, the first frame 110, the second frame 120 and the third frame 130 of the first frame structure 101a are embedded with the first magnetic structure 20a.

[0156] The magnetic structure 20 is arranged on the three frame structures surrounding the frame structure 10, which can achieve greater magnetic attraction. For example, a relatively small number of magnetic structures 20 with relatively low weight can achieve greater magnetic attraction, which is beneficial to the lightweight design of the electronic device.

[0157] In addition, the magnetic structure 20 is distributed in a decentralized manner on the three frame structures, and the strong magnetic attraction between the magnetic structures 20 can keep the first shell 101 and the second shell 102 in a relatively fixed state when the electronic device is in the closed state, so that the electronic device is stably kept closed. The decentralized distribution of the magnetic structure 20 makes the magnetic force relatively dispersed, and a relatively small force can be used to open the electronic device when the electronic device is switched from the closed state to the open state or the intermediate state. For example, by applying force to the corresponding two frame structures, such as the first frame of the first frame structure 101a and the first frame of the second frame structure 102a, the magnetic attraction between the corresponding two frame structures (such as the two first frames) can be overcome to open the two frame structures, so that the two frame structures 10 can be easily opened, which is more labor-saving and convenient for the user to apply force, and is beneficial to improving the use experience.

[0158] Alternatively, in some examples, the magnetic structure 20 can be arranged only on the second frame, for example, only on the second frame 120 of the first frame structure 101a and the second frame structure 102a as shown in FIGS. 3 and 4. Figure 16The first magnetic structure 20a is arranged on the second frame 120. The magnetic structures 20 on the two frame structures 10 are attracted to each other, so that the electronic device can be stably kept in a closed state. The number and weight of the magnetic structures 20 are reduced, and the electronic device is more suitable for thin and light design.

[0159] Alternatively, in some examples, the magnetic structures 20 can be arranged on the first frame and the third frame respectively, for example, as shown in FIG. 1B, the first magnetic structure 20a is arranged on the first frame 110 and the third frame 130. Figure 16 The first magnetic structure 20a is arranged on the first frame 110 and the third frame 130. The magnetic structures 20 on the two frames on the two sides (for example, the two sides along the length direction) are attracted to each other, so that the electronic device can be more stably kept in a closed state. The number and weight of the magnetic structures 20 are relatively small, and the dispersion degree of the magnetic structures 20 is relatively large, so that the electronic device is more labor-saving when opened.

[0160] It should be noted that in the embodiments of the present application, the number of magnetic structures 20 on each frame and the layout position of the magnetic structures 20 on the frame are not limited. For example, the first frame can have one or more magnetic structures 20, the second frame can also have one or more magnetic structures 20, and the third frame can also have one or more magnetic structures 20.

[0161] The number of magnetic structures 20 and the position of the magnetic structures 20 can be selected and set according to the shape, structure, size and strength of the frame. It can also be set in combination with the habit, hand feeling, experience demand and the like when opening the electronic device, for example, it can match the habit, hand feeling and the like when opening and closing the electronic device, such as to meet the demand that the magnetic attraction force is large when closed and it is more labor-saving when opened, adaptively make some areas of some frames have more magnetic structures 20 and the layout position is more compact, and the magnetic attraction force is larger, and some areas have fewer magnetic structures 20 and the layout position is more dispersed, and the magnetic attraction force is larger. For example, in some examples, the user is used to opening the electronic device from both sides, and the three frame structures 10 of the frame structure 10 have magnetic structures 20. More and more magnetic structures 20 can be arranged in the position adjacent to the second frame on the first frame and the third frame, so as to ensure that the magnetic attraction force is larger when closed, and it is convenient to open from the side and has a good hand feeling when opened.

[0162] Among them, Figure 16 An example of the number and layout position of the magnetic structures 20 on the first frame 101a is shown in FIG. 1A, for example, the first frame 110 and the third frame 130 can have two first magnetic structures 20a respectively, such as a first magnetic component 21a and a second magnetic component 21b. The second frame 120 can have four first magnetic structures 20a, such as a third magnetic component 21c, a fourth magnetic component 21d, a fifth magnetic component 21e and a sixth magnetic component 21f.

[0163] Figure 17 FIG. 4 is a schematic view of a front surface structure of another bezel structure in a bezel assembly according to an embodiment of the present application; Figure 18 Figure 17 FIG. 5 is a schematic view of a back surface structure of the bezel structure in FIG. 4.

[0164] In the bezel structure 10 shown in FIG. 4, the second bezel 102a can have a second outer surface 10d and a second inner surface 10b (see FIG. 5) opposite to each other along a thickness direction (z2 direction in the figure). Figure 17 In the bezel structure 10 shown in FIG. 4, the second bezel 102a can have a second outer surface 10d and a second inner surface 10b (see FIG. 5) opposite to each other along a thickness direction (z2 direction in the figure). Figure 18 When the electronic device is in the closed state, the second outer surface 10d of the second bezel 102a can be adjacent to and opposite to the first bezel, and the second outer surface 10d can be closer to the first bezel. The second inner surface 10b can be away from the first bezel, and the second inner surface 10b can face the second accommodating cavity in the second housing. When the electronic device is in the open state, the second outer surface 10d can be the appearance surface of the second bezel 102a.

[0165] The magnetic structure 20 can be embedded on the second inner surface 10b of the second bezel 102a, as shown in FIG. 5. Figure 18 The second magnetic structure 20b can be embedded on the second inner surface 10b of the second bezel 102a to ensure the appearance of the second outer surface 10d, as shown in FIG. 5.

[0166] The structure of the second bezel 102a can be the same as that of the first bezel. For example, the second bezel 102a can include a second frame portion 13 and a second extension portion 14. One side of the second extension portion 14 can form the first outer surface of the second bezel 102a. The second frame portion 13 can be arranged around the side of the second extension portion 14 away from the first outer surface. The second frame portion 13 can protrude from the second extension portion 14, so that the second frame portion 13 and the second extension portion 14 can form a stepped structure on the second inner surface 10b side of the second bezel 102a.

[0167] The second magnetic structure 20b can be embedded on the second frame portion 13. For example, the edge of the display screen can be arranged on the side of the second extension portion 14 away from the second outer surface, so that part of the second bezel 102a can be arranged around the display surface of the display screen.

[0168] Figure 19 FIG. 6 is a schematic view of a disassembled structure of the bezel assembly in FIG. 4, Figure 17 FIG. 7 is a schematic view of the magnetic structures on the two bezel structures in the bezel assembly in FIG. 4. Figure 20

[0169] ​​The arrangement of the second magnetic structure 20b on the second inner surface 10b can refer to the arrangement of the first magnetic structure 20a on the first inner surface 10a, for example, see Figure 19 As shown, a groove 15 can be formed on the second inner surface 10b of the second frame 102a, and the second magnetic structure 20b can be arranged in the groove 15.

[0170] The second magnetic structure 20b can be arranged in a semi-open manner on the second inner surface 10b, or can also be arranged in a closed manner, and the specific implementation manner can refer to the arrangement of the first magnetic structure 20a on the first inner surface 10a, which will not be described here.

[0171] The second frame 102a can include a first frame body 140, a second frame body 150 and a third frame body 160 arranged in sequence, and the connection and layout manner of the first frame body 140, the second frame body 150 and the third frame body 160 can refer to the first frame body 110, the second frame body 120 and the third frame body 130 in the first frame 101a.

[0172] The layout manner of the second magnetic structure 20b on the three frame bodies of the second frame 102a, the number of the second magnetic structure 20b and the layout position of the second magnetic structure 20b on each frame body are not limited, and it can be understood that the layout manner, number and layout position of the second magnetic structure 20b on the second frame 102a can correspond to the layout manner, number and layout position of the first magnetic structure 20a on the first frame 101a (see Figure 20 As described above, in the thickness direction, the vertical projections of the magnetic structures 20 (the first magnetic structure 20a and the second magnetic structure 20b) in the two frame structures 10 (the first frame 101a and the second frame 102a) at least partially overlap to ensure that the first frame 101a and the second frame 102a are attracted when the electronic device is closed.

[0173] The layout manner of the second magnetic structure 20b on the three frame bodies of the second frame 102a can refer to the layout manner of the first magnetic structure 20a on the three frame bodies of the first frame 101a, for example, the second magnetic structure 20b can be arranged on only part of the frame bodies, or the second magnetic structure 20b can be arranged on all the three frame bodies.

[0174] The number of the second magnetic structure 20b and the layout position of the second magnetic structure 20b on each frame body can be designed in correspondence with the number of the first magnetic structure 20a and the layout position of the first magnetic structure 20a on each frame body, and can also be selected and set in combination with the shape, structure, size and strength of the frame body.

[0175] Among them, Figure 19The diagram illustrates an example of the number and layout of magnetic structures 20 on a second border 102a. For instance, the first frame 140 and the third frame 160 of the second border 102a may each have two second magnetic structures 20b, such as a first magnetic unit 22a and a second magnetic unit 22b, respectively. The first magnetic unit 22a and the second magnetic unit 22b can respectively connect to the first magnetic component 21a and the second magnetic component 21b on the first border 101a (see reference). Figure 16 (As shown) Corresponds to the above. When the electronic device is in the closed state, see [reference]. Figure 20 As shown, the first magnetic component 21a and the first magnetic unit 22a attract each other, and the second magnetic component 21b and the second magnetic unit 22b attract each other.

[0176] See also Figure 19 As shown, the second frame 150 of the second border 102a may have four second magnetic structures 20b, such as a third magnetic unit 22c, a fourth magnetic unit 22d, a fifth magnetic unit 22e, and a sixth magnetic unit 22f. The third magnetic unit 22c, the fourth magnetic unit 22d, the fifth magnetic unit 22e, and the sixth magnetic unit 22f can respectively connect with the third magnetic component 21c, the fourth magnetic component 21d, the fifth magnetic component 21e, and the sixth magnetic component 21f on the first border 101a (see reference). Figure 16 (as shown) Corresponds to.

[0177] See Figure 20 As shown, when the electronic device is in the closed state, the third magnetic component 21c attracts the third magnetic unit 22c, the fourth magnetic component 21d attracts the fourth magnetic unit 22d, the fifth magnetic component 21e attracts the fifth magnetic unit 22e, and the sixth magnetic component 21f attracts the sixth magnetic unit 22f.

[0178] In some examples, each magnetic structure 20 may include a plurality of magnetic bodies 211 arranged in sequence; that is, each magnetic structure 20 is a group of magnetic bodies composed of a plurality of magnetic bodies 211. For example, Figure 19 As shown, taking the first magnetic unit 22a as an example, the first magnetic unit 22a includes multiple magnetic bodies 211. For example, the first magnetic unit 22a can be a component structure composed of 6 magnetic bodies 211.

[0179] Each magnetic structure 20 includes multiple magnetic bodies 211, which can be arranged in a distributed manner. The magnetic force distribution of the magnetic structure 20 is relatively dispersed. Compared with a single magnetic body 211, which is larger in size, the magnetic structure 20 can open electronic devices more easily, improving the user experience.

[0180] Moreover, the magnetic structure 20 includes a plurality of magnetic bodies 211 which can be distributedly arranged. The arrangement position, number and the like of the magnetic bodies 211 have high design flexibility, and can be arranged on the frame structure 10. The position and number of the magnetic bodies 211 can be flexibly designed according to the shape, size and strength and the like of the frame structure 10. The position and number of the magnetic bodies 211 can also be flexibly designed in combination with the opening habit, hand feeling and experience demand and the like of the electronic device, so as to adjust and realize different hand feeling and opening and closing demands, meet various use scenarios, and improve the use experience. For example, the magnetic attraction force can be increased in some areas by increasing the number of magnetic bodies 211 and reducing the distance between the magnetic bodies 211. The magnetic attraction force can be reduced in some areas by reducing the number of magnetic bodies 211 and increasing the distance between the magnetic bodies 211.

[0181] In the embodiments of the present application, the shape and size and the like of each magnetic body 211 are not limited. For example, the outer contour shape of the magnetic body 211 can be a regular or irregular shape such as a long strip shape, a trapezoidal shape, an L shape and the like.

[0182] The size of the magnetic body 211 can be relatively small. For example, taking the long strip-shaped magnetic body 211 as an example, the cross-sectional size thereof can be less than 1 mm*1 mm, which is beneficial to the thin design of the electronic device and has higher layout flexibility. For example, the outer contour shape and size and the like of the magnetic body 211 can be selectively set according to the structure, shape and size and the like of the frame structure 10.

[0183] The number of magnetic bodies 211 in each magnetic structure 20 can be the same, or the number of magnetic bodies 211 in at least part of the magnetic structures 20 can also be different. When the electronic device is in a closed state, the number of magnetic bodies 211 in the corresponding two magnetic structures 20 (for example, the corresponding first magnetic assembly 21a and the first magnetic unit 22a) can be the same or can also be different.

[0184] In some examples, the magnetic bodies 211 in the corresponding two magnetic structures 20 can all be hard magnets, which have a relatively large magnetic attraction force. For example, the forming material of the hard magnet is a hard magnetic material, for example, the forming material of the magnetic body 211 can be a ferrite, a neodymium iron boron, a samarium cobalt and the like.

[0185] Alternatively, in some examples, such as in a scenario where the magnetic force demand is relatively small, part of the magnetic bodies 211 in one of the two corresponding magnetic structures 20 can be hard magnets, and the magnetic bodies 211 corresponding to the hard magnets in the other magnetic structure 20 can be soft magnets. The magnetic attraction force between the two magnetic structures 20 can be reduced, and the flexibility of the design of the magnetic structure 20 can be improved.

[0186] The forming material of the soft magnet can be a soft magnetic material, for example, the forming material of the soft magnet can be silicon steel, iron-nickel alloy, ferrite, iron, etc.

[0187] For example, the first magnetic component 21a and the first magnetic unit 22a corresponding to each other are taken as an example, the first magnetic component 21a and the first magnetic unit 22a can each include 6 magnetic bodies 211, the 6 magnetic bodies in the first magnetic component 21a and the 6 magnetic bodies in the first magnetic unit 22a can correspond to each other and attract each other, and there are a total of 12 magnetic bodies 211. Figure 20

[0188] The 12 magnetic bodies 211 can each be a hard magnet. Alternatively, one or more magnetic bodies in the first magnetic component 21a can be a soft magnet, and one or more magnetic bodies corresponding to the soft magnet and attracting each other in the first magnetic unit 22a can be a hard magnet.

[0189] In the embodiments of the present application, the number and layout position of the hard magnet and the soft magnet in the magnetic structure 20 are not limited, and can be flexibly designed according to the opening habit, hand feeling and experience demand, etc., to adjust the magnetic attraction force between the magnetic structures 20.

[0190] In the embodiments of the present application, the polarity layout mode of the plurality of magnetic bodies 211 in the magnetic structure 20 is also not limited, and the magnetic bodies 211 can be arranged in the same polarity, staggered polarity, halbach polarity or other polarity layout mode, which can ensure that the corresponding magnetic structures 20 in the two frame structures 10 attract each other when the electronic device is in a closed state.

[0191] The polarity layout mode of the plurality of magnetic bodies 211 in the magnetic structure 20 is exemplarily illustrated below by taking the first magnetic structure 20a on the first frame 101a, such as the first magnetic component 21a, and the second magnetic structure 20b on the second frame 102a, such as the first magnetic unit 22a, as an example. The polarity layout mode of the magnetic bodies 211 in the other magnetic structures 20 on the first frame 101a and the second frame 102a can be referred to the first magnetic component 21a and the first magnetic unit 22a, and will not be described below.

[0192] Figure 21 A schematic diagram of the polarity layout mode of the magnetic bodies in the magnetic structure according to an embodiment of the present application is shown.

[0193] In some examples, the magnetic bodies 211 of the magnetic structure 20 can be arranged in the same polarity, for example, see Figure 21 ​As shown, the arrow direction is the polarity direction of the magnetic body 211. The polarity directions of the plurality of magnetic bodies 211 in the first magnetic assembly 21a can be consistent, the polarity directions of the plurality of magnetic bodies 211 in the first magnetic unit 22a can be consistent, the polarity directions of the first magnetic assembly 21a and the first magnetic unit 22a are consistent, so that the first magnetic assembly 21a and the first magnetic unit 22a are attracted to each other. The polarity design of the magnetic body 211 is relatively simple and easy to implement.

[0194] It should be noted that under the condition that the distance between the two corresponding magnetic structures 20 is constant, the length of the magnetic structure 20 is different along the arrangement direction of the magnetic body 211 (such as the x1 direction in the figure), and the magnetic force efficiency is different. When the length of the magnetic structure 20 is shorter, the plurality of magnetic bodies 211 in the magnetic structure 20 can be arranged in the same polarity mode, and the magnetic structure 20 can achieve a larger magnetic force efficiency.

[0195] For example, when the distance between the two corresponding magnetic structures 20 is about 1mm, the plurality of magnetic bodies 211 can be arranged in the same polarity mode when the length of the magnetic structure 20 is less than or equal to 6mm, and the magnetic structure 20 has high magnetic force efficiency.

[0196] It should be noted that in some examples, the length of the magnetic structure 20 can be designed according to the shape, size and strength of the frame body in the frame structure 10, as well as the opening and closing habits, hand feeling, magnetic force size design requirements of the user, and the like. The polarity layout mode of the magnetic body 211 is selectively set.

[0197] Figure 22 Another schematic diagram of the polarity layout mode of the magnetic body in the magnetic structure provided by the embodiment of the present application.

[0198] In some examples, the magnetic body 211 of the magnetic structure 20 can be arranged in an alternating polarity mode, and the polarity directions of any two adjacent magnetic bodies 211 in the plurality of magnetic bodies 211 can be opposite. For example, referring to Figure 22 As shown, the polarity of any two adjacent magnetic bodies 211 in the plurality of magnetic bodies 211 of the first magnetic assembly 21a is opposite, the polarity of any two adjacent magnetic bodies 211 in the plurality of magnetic bodies 211 of the first magnetic unit 22a is opposite, and the polarity of the two corresponding magnetic bodies 211 in the first magnetic assembly 21a and the first magnetic unit 22a can be consistent, so that the first magnetic assembly 21a and the first magnetic unit 22a are attracted to each other.

[0199] The polarities of the two adjacent magnetic bodies 211 are opposite, which can reduce the repulsion between the two adjacent magnetic bodies 211 in the same magnetic structure 20, facilitating assembly and implementation. Moreover, the magnetic attraction between the two corresponding magnetic structures 20 on the two frame structures 10 can be further improved, and the magnetic efficiency can be improved by about 5% to 10% compared with the above-mentioned arrangement of the same polarity.

[0200] For example, when the length of the magnetic structure 20 is greater than or equal to 30 mm, the plurality of magnetic bodies 211 can be arranged in the staggered polarity manner, and the magnetic structure 20 has high magnetic efficiency.

[0201] For example, when the length of the magnetic structure 20 is greater than or equal to 30 mm, the plurality of magnetic bodies 211 can be arranged in the staggered polarity manner, and the magnetic structure 20 has high magnetic efficiency.

[0202] Figure 23 Another schematic diagram of the polarity arrangement of the magnetic bodies in the magnetic structure is provided in the embodiments of the present application.

[0203] In some examples, the magnetic bodies 211 of the magnetic structure 20 can be arranged in the Halbach polarity manner, so that the magnetic structure 20 can be used as a Halbach magnet, which is beneficial to improve the magnetic efficiency. For example, the magnetic efficiency can be improved by about 10% to 20% compared with the above-mentioned arrangement of the same polarity.

[0204] For example, referring to FIG. 6, the polarity directions of the two adjacent magnetic bodies 211 are perpendicular to each other, and the included angle between the polarity directions is 90°. Figure 23 As shown in FIG. 6, in the plurality of magnetic bodies 211 of the first magnetic assembly 21a, the polarity directions of the two adjacent magnetic bodies 211 are perpendicular to each other, and the plurality of magnetic bodies 211 form a Halbach array, so that the first magnetic assembly 21a can be used as a Halbach magnet. In the plurality of magnetic bodies 211 of the first magnetic unit 22a, the polarity directions of the two adjacent magnetic bodies 211 are perpendicular to each other, and the plurality of magnetic bodies 211 form a Halbach array, so that the first magnetic unit 22a can be used as a Halbach magnet.

[0205] For example, referring to FIG. 6, the polarity directions of the two adjacent magnetic bodies 211 are perpendicular to each other, and the included angle between the polarity directions is 90°. Figure 23 For example, referring to FIG. 6, the polarity directions of the two adjacent magnetic bodies 211 are perpendicular to each other, and the included angle between the polarity directions is 90°.

[0206] For example, when the length of the magnetic structure 20 is greater than or equal to 30 mm, the plurality of magnetic bodies 211 can be arranged in the staggered polarity manner, and the magnetic structure 20 has high magnetic efficiency.

[0207] For example, when the length of the magnetic structure 20 is 6mm to 15mm, multiple magnetic bodies 211 can be arranged in a Heilbeck polarity manner, and the magnetic structure 20 has high magnetic efficiency.

[0208] In the example where the magnetic bodies 211 in the magnetic structure 20 are arranged in a Hellbeck polarity manner, the distance between the corresponding magnetic structures 20 that attract each other in the first frame 101a and the second frame 102a can be brought as close as possible. By utilizing the unilateral magnetic focusing effect of the Hellbeck magnet, the magnetic efficiency between the corresponding magnetic structures 20 in the two frame structures 10 can be improved.

[0209] Figure 24 This is a comparison diagram of the magnetic forces in a magnetic structure provided in this application embodiment, showing the magnetic bodies arranged in a same polarity manner and in a Hellbeck polarity manner.

[0210] like Figure 24 As shown in the figure, taking a magnetic body with dimensions of 10*17*2.3mm as an example, curve S1 in the figure shows the change of magnetic attraction between two corresponding magnetic structures (such as the first magnetic component 21a and the first magnetic unit 22a) in the two frame structures with different distances when the magnetic bodies are arranged in a same polarity manner. Curve S2 in the figure shows the change of magnetic attraction between two corresponding magnetic structures (such as the first magnetic component and the first magnetic unit) in the two frame structures with different distances when the magnetic bodies are arranged in a Helbeck polarity manner.

[0211] Depend on Figure 24 As shown, the smaller the distance between the two magnetic structures 20 that attract each other, the higher the magnetic efficiency of the magnet structure arranged in the Heilbeck polarity manner. For example, when the spacing is about 2.8 mm, the magnetic efficiencies of the two polarity distribution methods are quite similar.

[0212] For example, in the case where the magnetic bodies 211 in the magnetic structure 20 are arranged in a Hellbeck polarity manner, when the electronic device is in a closed state, the distance between the two magnetic structures 20 that are attracted to each other in the first frame 101a and the second frame 102a can be 0.55mm to 1.55mm, so that the magnetic structures 20 can achieve a greater magnetic attraction force.

[0213] For example, taking the first magnetic component 21a and the first magnetic unit 22a that are attracted to each other as an example, when the electronic device is in a closed state, the distance between the first magnetic component 21a and the first magnetic unit 22a is approximately 0.55mm to 1.55mm. Compared to arranging the first magnetic component 21a and the first magnetic unit 22a in the same polarity manner at the same distance, the first magnetic component 21a and the first magnetic unit 22a have a greater magnetic attraction.

[0214] The polarity layout of the magnetic body 211 can be selectively set according to the length of the magnetic structure 20, the distance between the magnetic structures 20 that can be arranged in the frame structure 10, and the like.

[0215] When the frame structure 10 has a plurality of magnetic structures 20, the polarity layout of the magnetic body 211 in the plurality of magnetic structures 20 can be the same, or the polarity layout of the magnetic body 211 in at least part of the magnetic structures 20 can be different.

[0216] Figure 25 For example, as shown in FIG. 1, the frame structure 10 has a first frame 101a, a second frame 102a, and a third frame 103a. Figure 15 FIG. 2 is a schematic view of a front view of the frame structure of FIG. 1. Figure 26 For example, as shown in FIG. 1, the frame structure 10 has a first frame 101a, a second frame 102a, and a third frame 103a. Figure 18 FIG. 2 is a schematic view of a front view of the frame structure of FIG. 1.

[0217] For example, as shown in FIG. 1, the frame structure 10 has a first frame 101a, a second frame 102a, and a third frame 103a. Figure 25 For example, as shown in FIG. 1, the frame structure 10 has a first frame 101a, a second frame 102a, and a third frame 103a.

[0218] For example, as shown in FIG. 1, the frame structure 10 has a first frame 101a, a second frame 102a, and a third frame 103a.

[0219] For example, as shown in FIG. 1, the frame structure 10 has a first frame 101a, a second frame 102a, and a third frame 103a. Figure 26 For example, as shown in FIG. 1, the frame structure 10 has a first frame 101a, a second frame 102a, and a third frame 103a.

[0220] For example, as shown in FIG. 1, the frame structure 10 has a first frame 101a, a second frame 102a, and a third frame 103a.
