Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a foldable electronic device. Background Art

[0002] With the continuous development of electronic technology, mobile phones, laptops, tablet computers and other terminal devices are becoming more and more deeply integrated into people's lives. People are also becoming more and more accustomed to watching videos, checking current events, and enjoying movies, sports events, etc. on mobile phones and other terminal products. In order to obtain a larger display screen to improve the user's viewing experience, foldable electronic devices are gradually becoming popular.

[0003] At present, foldable electronic devices usually include two relatively rotatable middle frames so that the foldable electronic device has a closed state and an unfolded state. When the foldable electronic device is closed, a certain force is required to maintain its closed state and closed feel. Magnets are usually installed on the two middle frames so that the two middle frames can be attracted by the magnets to achieve a firm connection and feel of the foldable electronic device in the closed state. However, the magnets are often large in size, and other electronic devices are usually installed on the middle frame. There is a certain spacing distance between the magnets installed on the middle frame and the other electronic devices. The spacing distance includes the wall thickness of the middle frame, the matching gap, etc., which will affect the arrangement of components in the foldable electronic device and reduce the space utilization rate inside the foldable electronic device. Summary of the invention

[0004] The present application provides a foldable electronic device to solve the problem that the magnets installed on the middle frame reduce the space utilization rate inside the foldable electronic device.

[0005] An embodiment of the present application provides a foldable electronic device, including a first middle frame, a second middle frame, an electronic device and a magnet assembly, wherein the second middle frame is rotatably connected to the first middle frame, the electronic device is arranged in the first middle frame or the second middle frame, the first middle frame and the second middle frame are attracted by the magnet assembly, the magnet assembly includes a first magnet, and the first magnet is arranged in the electronic device.

[0006] In the present application, the first magnet is arranged on the electronic device, and in the internal space of the foldable electronic device, the first magnet and the electronic device only include the gap distance n between the first magnet and the electronic device, so that the thickness of the first middle frame of the spacing part between the first magnet and the electronic device can be omitted, and the gap distance between the electronic device and the first middle frame of the spacing part and the gap distance between the first magnet and the first middle frame of the spacing part can also be omitted, thereby reducing the space occupied by the first magnet and the electronic device in the first direction and the second direction in the foldable electronic device, and improving the space utilization inside the foldable electronic device, so that the first magnet or the electronic device can have more installation space in the first direction and the second direction, so that the volume of the first magnet or the electronic device can be designed to be larger, so as to improve the performance of the first magnet or the electronic device and improve the user experience.

[0007] In one possible design, the electronic device is provided with a groove, and the first magnet is arranged in the groove, thereby reducing the stacking space of the electronic device and the first magnet in the third direction, reducing the thickness of the foldable electronic device in the third direction, and facilitating the lightweight design of the foldable electronic device in the third direction. The setting of the groove can limit the magnet in the first direction and the second direction to prevent the first magnet from being displaced in the plane, thereby improving the fixing effect of the first magnet in the groove and improving the structural stability of the foldable electronic device.

[0008] In a possible design, the groove includes a side wall, and a glue-containing groove is recessed on the side wall. By dispensing glue in the glue-containing groove, the first magnet located in the groove can be bonded to the side wall of the groove, thereby improving the tolerance of the first magnet in the groove, so that a first magnet of a smaller volume can still be firmly fixed in the groove, further improving the fixing effect of the first magnet in the groove, and enabling first magnets of different sizes to be stably located in the first groove, further improving the structural stability of the foldable electronic device.

[0009] In one possible design, the depth of the glue groove is d, 0.14mm≤d≤0.16mm. When the depth d of the glue groove satisfies 0.14mm≤d≤0.16mm, the depth of the glue groove is moderate, and the volume of glue that can be contained is sufficient, so that the first magnet can be firmly connected to the side wall of the groove and is not easy to fall off, thereby improving the fixing effect of the first magnet in the groove and improving the structural stability of the foldable electronic device. In addition, the glue groove of this depth is easy to process, has low process requirements, and is not easy to cause waste of glue materials, so that the glue dispensing is easy to fill the glue groove, reducing the manufacturing cost.

[0010] In a possible design, along the third direction of the foldable electronic device, the height of the glue groove is h1, 0.6mm≤h1≤0.8mm. When the height h1 of the glue groove satisfies 0.6mm≤h1≤0.8mm, the volume of the glue groove can be ensured to be moderate, and the volume of the contained glue can be sufficient, thereby ensuring the bonding effect between the first magnet and the side wall of the groove, making it difficult for the first magnet to fall off from the groove, thereby improving the structural stability of the foldable electronic device. The glue groove of this depth is also easy to process, with low process requirements, and is not prone to glue overflow, saving materials and reducing manufacturing costs.

[0011] In a possible design, the groove further includes a bottom wall, and a gap is formed between the bottom wall and the first magnet. By dispensing glue in the gap, the first magnet in the groove can be bonded to the bottom wall of the groove, thereby further improving the fixing effect of the first magnet in the groove and further improving the structural stability of the foldable electronic device.

[0012] In a possible design, along the third direction of the foldable electronic device, the distance of the gap is L, 0.1mm≤L≤0.15mm. When the distance L of the gap satisfies 0.1mm≤L≤0.15mm, there is a glue layer of moderate thickness between the first magnet and the bottom wall of the groove, thereby enhancing the bonding strength between the first magnet and the bottom wall, improving the bonding effect of the first magnet in the groove, so that the first magnet is not easy to detach from the groove, improving the structural stability of the foldable electronic device, and meeting the design requirements of the foldable electronic device to be lighter and thinner, and at a lower cost.

[0013] In one possible design, a boss is provided in the groove, and the boss is protruded from the bottom wall along the third direction of the foldable electronic device, so as to limit the displacement of the first magnet in the third direction, thereby ensuring that there is sufficient gap between the first magnet and the lowest point of the bottom wall in the third direction, thereby ensuring that the thickness of the glue layer is sufficient to ensure the bonding strength between the first magnet and the bottom wall, thereby improving the fixing effect of the first magnet in the groove.

[0014] In a possible design, the boss is convexly arranged at the corner of the bottom wall, so as to ensure that there is a sufficient gap distance L between the first magnet and the middle part of the bottom wall in the third direction, ensure the thickness of the glue layer, increase the bonding area between the first magnet and the bottom wall, further increase the bonding strength between the first magnet and the bottom wall, and further enhance the fixing effect of the first magnet in the groove.

[0015] In a possible design, along the third direction of the foldable electronic device, the height of the boss is h2, 0.05mm≤h2≤0.08mm. When the height h2 of the boss satisfies 0.05mm≤h2≤0.08mm, it can ensure that the gap distance L between the first magnet and the bottom wall is sufficient, thereby ensuring that the thickness of the glue layer is sufficient to ensure the bonding strength between the first magnet and the bottom wall, improve the fixing effect of the first magnet in the groove, and will not cause waste of coating glue, which is also conducive to the design requirements of a lighter and thinner foldable electronic device.

[0016] In one possible design, the electronic device is an audio component, which includes an upper cover, an inner core and a lower cover, wherein the inner core and the upper cover form a front cavity, and the inner core, the lower cover and the upper cover form a rear cavity, and at least a portion of the upper cover is recessed into the rear cavity to form the groove.

[0017] In this solution, at least part of the upper cover is recessed into the rear cavity to form the above-mentioned groove, which can reduce the thickness of the foldable electronic device in the third direction, which is conducive to the lightweight design of the foldable electronic device in the third direction. If the volume of the original first magnet is kept unchanged and the volume of the electronic device is designed to be larger, the electronic device as an audio component can have a larger rear cavity, thereby improving the bass effect of the electronic device, improving the audio performance of the foldable electronic device, and improving the user experience.

[0018] In one possible design, the lower cover is provided with an avoidance groove, and at least the portion of the upper cover that is recessed into the rear cavity is located in the avoidance groove, thereby ensuring the depth of the groove in the third direction, so as to enhance the limiting effect of the groove on the first magnet inside it, and further reduce the stacking space between the first magnet and the upper cover and the lower cover in the third direction, thereby further reducing the thickness of the foldable electronic device in the third direction, which is conducive to the lightweight and thin design of the foldable electronic device in the third direction.

[0019] In a possible design, the magnet assembly also includes a second magnet, the second magnet is arranged in one of the first middle frame or the second middle frame, the first magnet is arranged in the other of the first middle frame or the second middle frame, the first middle frame and the second middle frame are attracted by the first magnet and the second magnet, thereby ensuring that the foldable electronic device has a better feel when closed, and after closing, the first middle frame and the second middle frame can be stably connected to ensure the structural stability of the foldable electronic device.

[0020] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0069] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0070] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0071] In a specific embodiment, the present application is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0072] With the continuous development of electronic technology, mobile phones, laptops, tablet computers and other terminal devices are becoming more and more deeply integrated into people's lives. People are also becoming more and more accustomed to watching videos, checking current events, and enjoying movies, sports events, etc. on mobile phones and other terminal products. In order to obtain a larger display screen to improve the user's viewing experience, foldable electronic devices are gradually becoming popular.

[0073] Please refer to Figure 1 , Figure 1 FIG. 1 is a schematic diagram of the structure of a foldable electronic device in the prior art in an unfolded state. Figure 1 As shown, the existing foldable electronic device usually includes a first middle frame 1' and a second middle frame 2' that are relatively rotatable, so that the foldable electronic device has a closed state and an unfolded state. When the foldable electronic device is closed, a certain force is required to maintain its closed state and closed feel. Usually, magnets are installed on the first middle frame 1' and then the second middle frame 2'. For example, a first magnet 41' and a third magnet 43' are set on the first middle frame 1', and a second magnet 42' and a fourth magnet 44' are set on the second middle frame 2', so that the two middle frames can be attracted by the first magnet 41' and the second magnet 42' and the third magnet 43' and the fourth magnet 44' to achieve a firm connection and feel of the foldable electronic device in the closed state.

[0074] However, the volume of the magnet is often large, and other electronic devices 3' are usually installed on the first middle frame 1' or the second middle frame 2'. Figure 1As shown, the first magnet 41' and the electronic device 3' are arranged on the first middle frame 1', and there is a certain interval between the first magnet 41' and the electronic device 3', and the interval includes the gap distance a of the first middle frame 1' in the interval between the electronic device 3' and the first middle frame 1', the thickness b of the first middle frame 1' in the interval between the first magnet 41' and the electronic device 3', and the gap c between the first magnet 41' and the first middle frame 1' in the interval, which occupies more space in the first direction X and the second direction Y in the electronic device, so that it is easy to affect the arrangement of other components in the foldable electronic device, so that the space utilization rate inside the foldable electronic device is reduced.

[0075] In order to solve the above technical problems, the embodiment of the present application provides a foldable electronic device, which includes any device with a foldable screen function, such as a mobile phone, a tablet computer, a personal digital assistant (PDA), a laptop computer, a car computer, a foldable display device, a foldable display screen, a wearable device, etc. The embodiment of the present application does not impose any special restrictions on the specific form of the above electronic device. For the convenience of explanation, the following description is made by taking the foldable electronic device as an example of a foldable mobile phone. The electronic device of the present application is introduced in the following specific embodiments.

[0076] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a foldable electronic device provided by the present application in an unfolded state. Figure 2 As shown, the foldable electronic device includes a first middle frame 1, a second middle frame 2 and a hinge 5. The first middle frame 1 and the second middle frame 2 are rotatably connected via the hinge 5. When the first middle frame 1 and the second middle frame 2 rotate around the hinge 5 and approach each other, the foldable electronic device can be transformed from an unfolded state to a closed state, thereby reducing the overall size of the foldable electronic device and making it easier for users to carry.

[0077] Furthermore, the first middle frame 1 or the second middle frame 2 may be provided with an electronic device 3, so that the foldable electronic device has multiple functions and good performance. The electronic device 3 may be a voice recognition module, a camera module, an audio component, etc., which is not limited here. In the embodiment of the present application, the electronic device 3 is an audio component as an example for explanation, and as Figure 2 In the specific embodiment shown, the electronic device 3 is arranged on the first middle frame 1 .

[0078] Furthermore, if Figure 2 As shown, the foldable electronic device further includes a magnet assembly 4. When the foldable electronic device is in a closed state, the first middle frame 1 and the second middle frame 2 are attracted by the magnet assembly 4, thereby achieving a firm connection and a good feel in the folded state.

[0079] Among them, the magnet assembly 4 may include a plurality of magnets, and the plurality of magnets are respectively arranged on the first middle frame 1 and the second middle frame 2 to improve the suction stability of the first middle frame 1 and the second middle frame 2. Of course, the magnet assembly 4 may also include a block structure made of a part of magnets and a part of materials that can be attracted by magnets, and the block structure and the magnets are respectively arranged on the first middle frame 1 and the second middle frame so that their positions are opposite, so that they can be attracted to each other when the foldable electronic device is closed, and the first middle frame 1 and the second middle frame 2 can be stably connected after closing, and the cost is lower, which is not limited here.

[0080] For example, Figure 2 As shown, the magnet assembly 4 includes a first magnet 41, a second magnet 42, a third magnet 43 and a fourth magnet 44. The first magnet 41 and the third magnet 43 are arranged on the first middle frame 1, and the second magnet 42 and the fourth magnet 44 are arranged on the second middle frame 2. The first magnet 41 and the second magnet 42 are positioned relative to each other and have opposite magnetic properties. The third magnet 43 and the fourth magnet 44 are positioned relative to each other and have opposite magnetic properties. Therefore, when the foldable electronic device is closed, the first magnet 41 and the second magnet 42 are attracted to each other, and the third magnet and the fourth magnet are attracted to each other, thereby ensuring that the foldable electronic device has a better feel when closed, and after closing, the first middle frame 1 and the second middle frame 2 can be stably connected to ensure the structural stability of the foldable electronic device.

[0081] Furthermore, the first magnet 41, the second magnet 42, the third magnet 43 and the fourth magnet 44 of the magnet assembly 4 can be arranged on the electronic device 3 located on the same middle frame to reduce the spacing distance between the magnets and the electronic device 3, reduce the space occupied by the magnets and the electronic device 3 in the first direction X and the second direction Y in the foldable electronic device, and improve the space utilization inside the foldable electronic device.

[0082] For example, Figure 2 As shown, the electronic device 3 and the first magnet 41 in the magnet assembly 4 are both arranged on the first middle frame 1 , wherein the electronic device 3 is connected to the first middle frame 1 , and the first magnet 41 is connected to the electronic device 3 .

[0083] Compared with the prior art, the first magnet 41 and the electronic device 3 are spaced apart on the first middle frame 1. In this embodiment, Figure 2As shown, the first magnet 41 is arranged on the electronic device 3. In the internal space of the foldable electronic device, the first magnet 41 and the electronic device 3 only include the gap distance n between the first magnet 41 and the electronic device 3, so that the thickness of the first middle frame 1 in the spacing portion between the first magnet 41 and the electronic device 3 can be omitted, and the gap distance between the electronic device 3 and the first middle frame 1 in the spacing portion and the gap distance between the first magnet 41 and the first middle frame 1 in the spacing portion can also be omitted, thereby reducing the occupied space of the first magnet 41 and the electronic device 3 in the first direction X and the second direction Y in the foldable electronic device, and improving the space utilization inside the foldable electronic device, so that the first magnet 41 or the electronic device 3 can have more installation space in the first direction X and the second direction Y, so that the volume of the first magnet 41 or the electronic device 3 can be designed to be larger, so as to improve the performance of the first magnet 41 or the electronic device 3 and improve the user experience.

[0084] Among them, Figure 2 As shown, if the overall volume of the original electronic device 3 is kept unchanged and the volume of the first magnet 41 is designed to be larger in the first direction X and the second direction Y, the area of ​​the first magnet 41 in the first direction X and the second direction Y is larger, the magnetism is better, and it is more conducive to the first magnet 41 and the second magnet 42 arranged on the second middle frame 2 to attract each other, thereby improving the feel of the foldable electronic device when it is unfolded or closed, and can further ensure the firm connection of the foldable electronic device in the closed state, thereby improving the user experience.

[0085] like Figure 2 As shown, if the volume of the original first magnet 41 is kept unchanged and the volume of the electronic device 3 is designed to be larger, taking the electronic device 3 as an audio component as an example, the electronic device 3 as an audio component can have a larger back cavity, or can achieve the installation of a larger core, thereby further improving the sound effect of the audio component, improving the audio performance of the foldable electronic device, and improving the user experience.

[0086] For further information, please refer to Figure 3 and Figure 4 , Figure 3 for Figure 2 A schematic diagram of a part of the structure of a foldable electronic device. Figure 4 for Figure 3 Schematic diagram of the decomposition of Figure 4 As shown, a hollow recessed portion 11 is provided on the first middle frame 1 , and at least part of the electronic device 3 is located in the recessed portion 11 . A groove 311 is provided on the side of the electronic device 3 facing the first magnet 41 , and the first magnet 41 is disposed in the groove 311 .

[0087] In this embodiment, Figure 4As shown, the structure can reduce the stacking space of the electronic device 3, the first middle frame 1 and the first magnet 41 in the third direction Z, reduce the thickness of the foldable electronic device in the third direction Z, and is conducive to the lightweight design of the foldable electronic device in the third direction Z. The setting of the groove 311 can limit the magnet 41 in the first direction X and the second direction Y to prevent the first magnet 41 from being displaced in the plane, thereby improving the fixing effect of the first magnet 41 in the groove 311 and improving the structural stability of the foldable electronic device.

[0088] like Figure 2 As shown, in order to facilitate the fixation of the second magnet 42, the third magnet 43 and the fourth magnet 44 installed on the first middle frame 1 and the second middle frame 2 in the magnet assembly 4, and to reduce the thickness of the foldable electronic device in the third direction, corresponding grooves can be opened on the first middle frame 1 and the second middle frame 2 so that the second magnet 42, the third magnet 43 and the fourth magnet 44 are located in the grooves.

[0089] For example, Figure 2 As shown, in the magnet assembly 4, the first magnet 41, the second magnet 42, the third magnet 43 and the fourth magnet 44 are all roughly rectangular, and some of them are designed with rounded corners. The magnet structure is simple, easy to process and form, and also convenient for opening corresponding grooves on the first middle frame 1, the second middle frame 2 and the electronic device 3, thereby reducing the preparation cost.

[0090] For example, Figure 4 As shown, the first magnet 41 can also be set to be roughly L-shaped, and the groove 311 on the electronic device 3 matches the shape of the first magnet 41, which can further improve the limiting effect of the first magnet 41 and prevent the first magnet 41 from rotating in the groove 311, thereby further improving the fixing effect of the first magnet 41 in the groove 311 and improving the structural stability of the foldable electronic device.

[0091] Of course, the shapes of the individual magnets of the magnet assembly 4 (for example, the first magnet 41, the second magnet 42, the third magnet 43 and the fourth magnet 44) can also be parallelograms, trapezoids, triangles, circles, ellipses, T-shaped, etc. or other irregular shapes, and the shapes of the individual magnets can be the same or different. The shape of the groove corresponding to each magnet is matched with the shape of the magnet arranged inside it to increase the design freedom of the foldable electronic device, which is not limited here.

[0092] Further, taking the electronic device 3 as an audio component as an example, please refer to Figures 5 to 9 As shown, Figure 5 for Figure 3 Another decomposition diagram of Figure 6 for Figure 3 A top view of the structure in the middle. Figure 7 for Figure 6 Cross-sectional view along AA direction, Figure 8 for Figure 6 Cross-sectional view along BB direction, Fig. 9 for Figure 6 Cross-sectional view along CC direction.

[0093] like Figure 5 As shown, the electronic device 3 as an audio component includes an upper cover 31 , a core 32 and a lower cover 33 . The upper cover 31 is connected to the lower cover 33 , and the core 32 is arranged between the upper cover 31 and the lower cover 33 .

[0094] like Figure 7 As shown, the electronic device 3 further includes a sound cavity formed by an upper cover 31 and a lower cover 33, and the inner core 32 divides the sound cavity into a front cavity 34 and a rear cavity 35. Specifically, the inner core 32 and the upper cover 31 form the front cavity 34, and the inner core 32, the lower cover 33 and the upper cover 31 form the rear cavity 35. Figure 7 and Figure 8 As shown, at least a portion of the upper cover 31 is recessed into the rear cavity 35 to form the above-mentioned groove 311 .

[0095] In this embodiment, Figure 8 As shown, at least a portion of the upper cover 31 is recessed into the rear cavity 35 to form the above-mentioned groove 311, which can reduce the thickness of the foldable electronic device in the third direction Z, and is conducive to the lightweight design of the foldable electronic device in the third direction Z. If the volume of the original first magnet 41 is kept unchanged, the volume of the electronic device 3 can be designed to be larger, and the electronic device 3 as an audio component can have a larger rear cavity 35, thereby improving the bass effect of the electronic device 3, improving the audio performance of the foldable electronic device, and improving the user experience.

[0096] Furthermore, if Figure 5 , Figure 7 and Figure 8 As shown, an avoidance groove 331 is provided on the lower cover 33, and at least a portion of the upper cover 31 that is recessed into the rear cavity 35 is located in the avoidance groove 331, thereby ensuring the depth of the groove 311 in the third direction Z, so as to enhance the limiting effect of the groove 311 on the first magnet 41 therein, and further reduce the stacking space between the first magnet 41 and the upper cover 31 and the lower cover 33 in the third direction Z, thereby further reducing the thickness of the foldable electronic device in the third direction Z, which is conducive to the lightweight design of the foldable electronic device in the third direction Z.

[0097] Furthermore, if Fig. 9 As shown, a sound outlet channel 317 communicating with the front cavity 34 is provided on the side of the upper cover 31. Figure 5The sound outlet hole 12 set on the first middle frame 1 is connected, so that the front cavity 34 of the electronic device 3 can be connected with the outside world through the sound outlet channel 317 and the sound outlet hole 12 in sequence to ensure the sound output effect of the electronic device 3.

[0098] For further information, please refer to Fig.10 , Fig.10 for Figure 7 A partial enlarged view of point D in the figure. Fig.10 As shown, a glue containing groove 313 is recessed on the side wall 312 of the groove 311 , and the glue containing groove 313 is used to contain glue.

[0099] In this embodiment, Fig.10 As shown, by dispensing glue in the glue groove 313, the first magnet 41 located in the groove 311 can be bonded to the side wall 312 of the groove 311, thereby improving the fault tolerance of the first magnet 41 in the groove 311, so that a first magnet 41 with a smaller volume can still be firmly fixed in the groove 311, further improving the fixing effect of the first magnet 41 in the groove 311, and enabling first magnets 41 of different sizes to be stably located in the first groove 311, further improving the structural stability of the foldable electronic device.

[0100] Furthermore, if Fig.10 As shown, the depth of the adhesive groove 313 is d, and satisfies 0.14 mm ≤ d ≤ 0.16 mm. For example, d can be 0.14 mm, 0.15 mm, 0.16 mm, etc., and can be specifically designed according to actual needs, and is not limited here.

[0101] like Fig.10 As shown, the depth d of the glue groove 313 cannot be too deep or too shallow. If the depth d of the glue groove 313 is too deep, for example, d>0.16mm, too much glue needs to be filled, and too much glue is easily overflowed, which easily causes waste of materials. In addition, when dispensing glue into the glue groove 313, it is not easy to fill the glue groove 313, which reduces the bonding effect of the first magnet 41 in the groove 311. In addition, the glue groove 313 is too deep and difficult to form, and the process requirements are high, resulting in higher manufacturing costs. If the depth d of the glue groove 313 is too shallow, for example, d<0.14mm, the glue groove 313 can accommodate less glue, thereby reducing the bonding effect between the first magnet 41 and the side wall 312 of the groove 311, causing the first magnet 41 to fall off easily.

[0102] In this embodiment, Fig.10As shown, when the depth d of the glue groove 313 satisfies 0.14mm≤d≤0.16mm, the depth of the glue groove 313 is moderate, and the volume of glue that can be accommodated is sufficient, so that the first magnet 41 can be firmly connected to the side wall 312 of the groove 311 and is not easy to fall off, thereby improving the fixing effect of the first magnet 41 in the groove 311 and improving the structural stability of the foldable electronic device. The glue groove 313 of this depth is easy to process, has low process requirements, and is not easy to cause waste of glue materials, so that the glue dispensing can easily fill the glue groove 313, thereby reducing the manufacturing cost.

[0103] In the embodiment of the present application, the depth d of the glue groove 313 is 0.15 mm, and the glue groove 313 is easily filled with glue during dispensing, thereby improving the bonding effect of the first magnet 41 in the groove 311 .

[0104] Furthermore, if Fig.10 As shown, along the third direction Z of the foldable electronic device, the height of the adhesive groove 313 is h1, and satisfies 0.6mm≤h1≤0.8mm. For example, h1 can be 0.6mm, 0.7mm, 0.8mm, etc., and can be specifically designed according to actual needs, and is not limited here.

[0105] like Fig.10 As shown, if h1 is too large, for example, h1>0.8mm, the volume of the glue groove 313 is too large, the amount of glue that needs to be filled in the glue groove 313 is too much, and glue overflow is likely to occur, which easily causes waste of materials; if h1 is too small, for example, h1<0.6mm, the volume of the glue groove 313 is too small, and the amount of glue contained is small, thereby reducing the bonding effect between the first magnet 41 and the side wall 312 of the groove 311, thereby reducing the fixing effect of the first magnet 41 in the groove 311, causing the first magnet 41 to fall off easily.

[0106] In this embodiment, Fig.10 As shown, Fig.10 As shown, when the height h1 of the glue groove satisfies 0.6mm≤h1≤0.8mm, the volume of the glue groove 313 can be ensured to be moderate, and the volume of the contained glue is sufficient, thereby ensuring the bonding effect between the first magnet 41 and the side wall 312 of the groove 311, making it difficult for the first magnet 41 to fall off from the groove 311, thereby improving the structural stability of the foldable electronic device. The glue groove 313 of this depth is also easy to process, has low process requirements, and is not prone to glue overflow, thereby saving materials and reducing manufacturing costs.

[0107] Furthermore, if Fig.10 As shown, there is a gap 315 between the bottom wall 314 of the groove 311 and the first magnet 41 , and the gap 315 is also used to accommodate glue.

[0108] In this embodiment, Fig.10As shown, by dispensing glue in the gap 315, the first magnet 41 located in the groove 311 can be bonded to the bottom wall 314 of the groove 311, further improving the fixing effect of the first magnet 41 in the groove 311 and further improving the structural stability of the foldable electronic device.

[0109] Furthermore, if Fig.10 As shown, along the third direction Z of the foldable electronic device, the distance of the gap 315 is L, and satisfies 0.1mm≤L≤0.15mm. For example, L can be 0.1mm, 0.12mm, 0.15mm, etc., and can be specifically designed according to actual needs, and is not limited here.

[0110] like Fig.10 As shown, if the gap distance L is too small, for example L<0.1mm, the glue between the first magnet 41 and the bottom wall 314 of the groove 311 is too thin, which may easily lead to a low bonding strength between the first magnet 41 and the bottom wall 314, thereby making the first magnet 41 easily detached from the groove 311; if the gap distance L is too large, for example L>0.15mm, the glue is too thick, which will increase the stacking space between the first magnet 41 and the upper cover 31 in the third direction Z, which is not conducive to the lightweight design of the foldable electronic device, and will cause waste of glue materials and increase manufacturing costs.

[0111] In this embodiment, Fig.10 As shown, when the distance L of the gap 315 satisfies 0.1mm≤L≤0.15mm, there is a glue layer of moderate thickness between the first magnet 41 and the bottom wall 314 of the groove 311, thereby enhancing the bonding strength between the first magnet 41 and the bottom wall 314, and improving the bonding effect of the first magnet 41 in the groove 311, so that the first magnet 41 is not easy to detach from the groove 311, thereby improving the structural stability of the foldable electronic device, and can meet the design requirements of the foldable electronic device to be lighter and thinner, and at a lower cost.

[0112] In the embodiment of the present application, the distance L of the gap 315 is 0.1 mm, which can save glue materials to the greatest extent, ensure the bonding effect between the first magnet 41 and the bottom wall 314 of the groove 311, and make the foldable electronic device thinner and lighter.

[0113] It should be noted that if Fig.10 As shown, the gap 315 and the glue-containing groove 313 can be simultaneously arranged in the same groove 311, and the gap 315 and the glue-containing groove 313 cooperate to contain glue, so that the first magnet 41 can be bonded to the side wall 312 and the bottom wall 314 of the groove 311 at the same time, further improving the fixing effect of the first magnet 41 in the groove 311. Of course, only one of the gap 315 and the glue-containing groove 313 can also be arranged in the groove 311, which is not limited here.

[0114] Furthermore, if Fig.10 As shown, a boss 316 is disposed in the groove 311 , and along the third direction Z of the foldable electronic device, the boss 316 is protruded from the bottom wall 314 .

[0115] In this embodiment, Fig.10 As shown, the bottom wall 314 of the groove 311 is provided with a boss 316, which can limit the displacement of the first magnet 41 in the third direction Z, thereby ensuring that there is a sufficient gap 315 between the first magnet 41 and the lowest point of the bottom wall 314 in the third direction Z, thereby ensuring that the thickness of the glue layer is sufficient to ensure the bonding strength between the first magnet 41 and the bottom wall 314, and improving the fixing effect of the first magnet 41 in the groove 311.

[0116] For further information, please refer to Fig.11 and Fig.12 , Fig.11 for Figure 5 Top view of the middle upper cover. Fig.12 for Fig.11 A schematic diagram of the structure of the middle groove in another embodiment. Fig.11 and Fig.12 As shown, the boss 316 is protruding from the corner of the bottom wall 314, so as to ensure that there is a sufficient gap distance L between the first magnet 41 and the middle part of the bottom wall 314 in the third direction Z, thereby ensuring the thickness of the glue layer, and increasing the bonding area between the first magnet 41 and the bottom wall 314, further increasing the bonding strength between the first magnet 41 and the bottom wall 314, and further improving the fixing effect of the first magnet 41 in the groove 311.

[0117] like Fig.11 In the specific embodiment shown, the shape of the groove 311 is irregular and roughly L-shaped, and the boss 316 can be set at each corner of the groove 311 in the figure. Of course, it can also be set at some corners to further reduce the difficulty of preparation and save preparation costs. There is no limitation here.

[0118] like Fig.12 In the specific embodiment shown, the groove 311 is rectangular in shape, the bosses 316 can be arranged at the four corners, and some of the bosses can be connected to enhance the limiting effect of the first magnet 41 in the third direction Z, thereby ensuring that the gap distance between the first magnet 41 and the middle part of the bottom wall 314 is sufficient.

[0119] Of course, the bosses 316 may also be uniformly protruded from the edge of the bottom wall 314 to further improve the limiting effect of the first magnet 41 in the third direction Z, which is not limited here.

[0120] Furthermore, if Fig.10As shown, along the third direction Z of the foldable electronic device, the height of the boss 316 is h2, 0.05mm≤h2≤0.08mm. For example, h2 can be 0.05mm, 0.06mm, 0.07mm, 0.08mm, etc., which can be set according to actual needs and is not limited here.

[0121] As shown in 10, if the height of h2 is relatively low, for example, h2 < 0.05mm, the limiting effect on the first magnet 41 in the third direction Z is relatively poor, thereby failing to ensure that the gap distance L between the first magnet 41 and the bottom wall 314 is sufficient; if the height of h2 is relatively high, for example, h2 is greater than 0.08mm, the gap distance L between the first magnet 41 and the bottom wall 314 is too large, thereby causing a waste of glue coating and increasing the thickness of the foldable electronic device in the third direction Z, which is not conducive to the design requirement of a thinner and lighter foldable electronic device.

[0122] In this embodiment, Fig.10 As shown, when the height h2 of the boss 316 satisfies 0.05mm≤h2≤0.08mm, it can ensure that the gap distance L between the first magnet 41 and the bottom wall 314 is sufficient, thereby ensuring that the thickness of the glue layer is sufficient, so as to ensure the bonding strength between the first magnet 41 and the bottom wall 314, enhance the fixing effect of the first magnet 41 in the groove 311, and will not cause waste of the coated glue, which is also beneficial to the design requirement of a lighter and thinner foldable electronic device.

[0123] In the embodiment of the present application, the height h2 of the boss 316 is 0.05 mm, which can ensure that there is a sufficient gap distance L between the first magnet 41 and the bottom wall 314 and can make the foldable electronic device thinner and lighter.

Therefore, the protection scope of the embodiment of the present application should be based on the protection scope of the claims.
