[0025] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments, not all of the embodiments. Based on the embodiments provided in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present application.

[0026] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It can be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0027] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example: a component or device including one or more parts is not limited to the one or more parts listed, but optionally includes one or more parts that are not listed but inherent to the exemplified product, or one or more parts that it should have based on the described function.

[0028] Before introducing the electronic device provided by the embodiments of the present application, the electronic device in the related art is first introduced. The electronic device in the related art usually includes an integrated middle frame structure to meet the requirements of higher waterproof standards (such as IP68 or IP69). The fact that the electronic device includes an integrated middle frame structure determines that the electronic device must use the frame of the integrated middle frame structure to form the radiator of the antenna. For example, a computer numerical control (CNC) processing technology with a relatively high process cost is used to process an antenna seam in the frame of the integrated middle frame structure to form the radiator of the antenna. In addition, the appearance and structural disassembly of the electronic device including the integrated middle frame structure are limited. In summary, the appearance and structural disassembly of electronic devices with higher waterproof standards (such as IP68 or IP69) in the related art are limited, and the cost is relatively high.

[0029] Next, the electronic device 1 provided in the embodiment of the present application is introduced in detail. The embodiment of the present application provides an electronic device 1, and the electronic device 1 can be but is not limited to a mobile phone, a watch, a tablet computer, a laptop computer and other devices. In the embodiment of the present application, the electronic device 1 is illustrated and described as a mobile phone as an example, which is understandable and should not be understood as a limitation on the embodiment of the present application.

[0030] Please also read Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 A schematic diagram of an electronic device provided in one embodiment of the present application; Figure 2 for Figure 1 A perspective exploded schematic diagram of the electronic device shown; Figure 3 An implementation method provided Figure 1 A schematic cross-sectional view of the electronic device shown in FIG. 1 along line II; Figure 4 for Figure 3An enlarged schematic diagram of the middle II. The electronic device 1 includes a middle frame 10, a front shell 20, an antenna 30 and a first seal 610. The middle frame 10 includes a frame body 110 and a side frame 120. The side frame 120 is bent and connected to the periphery of the frame body 110. The front shell 20 includes a front shell body 210 and a peripheral portion 220. The peripheral portion 220 is bent and connected to the periphery of the front shell body 210. The peripheral portion 220, the front shell body 210 and the frame body 110 cooperate to form a receiving space 20a. There is a first gap 20b between the peripheral portion 220 and the side frame 120. The peripheral portion 220 has a receiving groove 20c, and the receiving groove 20c is connected to the first gap 20b. The front shell 20 also has a through hole 20d that passes through the receiving groove 20c and the receiving space 20a. The antenna 30 includes a radiator 310. The radiator 310 is located in the first gap 20b, the receiving groove 20c, the through hole 20d and the accommodating space 20a. The first sealing member 610 is located in the receiving groove 20c and surrounds the periphery of the radiator 310 to seal the front housing 20 and the radiator 310.

[0031] In one embodiment, the middle frame 10 is the ground electrode in the electronic device 1, and the electronic devices of the electronic device 1 are electrically connected to the middle frame 10 for grounding. In this embodiment, the electronic device 1 includes a middle frame 10 and a front shell 20. Therefore, the front shell 20 and the middle frame 10 are split structures. Since the middle frame 10 and the front shell 20 are split structures, the middle frame 10 can be called a middle frame disassembled part, and the front shell 20 is also called a front shell disassembled part. In one embodiment, the material of the middle frame 10 can be metal, and the material of the front shell 20 can be but is not limited to plastic. When the material of the front shell 20 is plastic, the front shell 20 has a continuous and complete plastic surface.

[0032] Please also read Figure 3 and Figure 5 , Figure 5 for Figure 3 Detailed identification schematic diagram of the cross-sectional view of the electronic device shown in . The middle frame 10 includes a frame body 110 and a side frame 120. The frame body 110 is the large surface part of the middle frame 10, also referred to as the main body. In the present embodiment, the frame body 110 includes a first surface 110a and a second surface 110b that are arranged opposite to each other. In the schematic diagram of the present embodiment, the first surface 110a is taken as the upper surface of the frame body 110, and the second surface 110b is taken as the lower surface of the frame body 110 for illustration. It can be understood that as the placement posture of the electronic device 1 is different, the relative positions of the first surface 110a and the second surface 110b are also different.

[0033] The side frame 120 is bent and connected to the periphery of the frame body 110, and the side frame 120 at least protrudes from at least one of the first surface 110a and the second surface 110b of the frame body 110. In this embodiment, the side frame 120 protrudes from the first surface 110a of the frame body 110, and the side frame 120 protrudes from the second surface 110b of the frame body 110 is used as an example for illustration.

[0034] The front shell 20 is located on one side of the first surface 110a of the frame body 110. The front shell 20 includes a front shell body 210 and a peripheral portion 220. The front shell body 210 is the large surface portion of the front shell 20, and is also called the main body. Figure 3 and Figure 5 In this embodiment, the front shell body 210 includes a third surface 210a and a fourth surface 210b that are disposed opposite to each other. In the schematic diagram of this embodiment, the third surface 210a is taken as the upper surface of the front shell body 210, and the fourth surface 210b is taken as the lower surface of the front shell body 210. In other words, the third surface 210a is the surface of the front shell body 210 that is away from the frame body 110, and the fourth surface 210b is the surface of the front shell body 210 that is adjacent to the frame body 110. It can be understood that as the placement posture of the electronic device 1 is different, the relative positions of the third surface 210a and the fourth surface 210b are also different.

[0035] The peripheral portion 220 is bent and connected to the periphery of the front shell body 210, and the peripheral portion 220 protrudes from at least one of the third surface 210a and the fourth surface 210b of the front shell body 210. In the embodiment, the peripheral portion 220 protrudes from the third surface 210a of the front shell body 210, and the peripheral portion 220 protrudes from the fourth surface 210b of the front shell body 210 is used as an example for illustration.

[0036] The peripheral portion 220, the front shell body 210 and the frame body 110 cooperate to form a receiving space 20a. The peripheral portion 220 of the front shell 20 is at least partially located inside the side frame 120. The peripheral portion 220 and the side frame 120 are spaced apart to form a first gap 20b. The peripheral portion 220 has a receiving groove 20c. In this embodiment, the surface of the peripheral portion 220 facing the side frame 120 has the receiving groove 20c. The receiving groove 20c is connected to the first gap 20b. The front shell 20 also has a through hole 20d. In one embodiment, the through hole 20d is located at the peripheral portion 220; in another embodiment, the through hole 20d is located at the peripheral portion 220 and the front shell body 210; in yet another embodiment, the through hole 20d is located at the front shell body 210. The embodiment of the present application does not limit the position of the through hole 20d, as long as the through hole 20d connects the receiving groove 20c and the accommodating space 20a. It can be seen that the first gap 20b, the receiving groove 20c, the through hole 20d and the accommodating space 20a are connected.

[0037] The antenna 30 includes a radiator 310, and the radiator 310 may be, but is not limited to, a flexible circuit board (FPC) radiator 310. The radiator 310 is located in the first gap 20b, the receiving groove 20c, the through hole 20d, and the accommodating space 20a. It can be seen that the radiator 310 is an independent radiator independent of the middle frame 10. Compared with the radiator formed on the integrated middle frame structure of the electronic device 1 in the related art, the radiator 310 provided in the embodiment of the present application is an independent radiator independent of the middle frame 10, which has a lower cost.

[0038] A portion of the radiator 310 is located in the first gap 20 b . For example, the portion of the radiator 310 located in the first gap 20 b is attached to a surface of the peripheral portion 220 facing the side frame 120 .

[0039] In one embodiment, the antenna 30 further includes a feed source. Accordingly, the electronic device 1 further includes a circuit board. The circuit board is located in the accommodating space 20a. The circuit board is used to carry the feed source. The radiator 310 has a feed point at one end of the accommodating space 20a, and the feed point is electrically connected to the circuit board through an electrical connector (e.g., a conductive spring, or conductive glue, or a conductive screw, etc.) to electrically connect the feed point of the radiator 310 to the feed source. When the electrical connector is a conductive spring, the way in which the electrical connector is electrically connected to the circuit board may not be limited to a front connection (also referred to as a positive spring) or a side connection (also referred to as a side spring). The feed source is used to excite the radiator 310 to receive and / or transmit electromagnetic wave signals. In one embodiment, the radiator 310 also fixes the portion of the radiator 310 located in the accommodating space 20a to a preset position through a positioning member 810 (also referred to as a positioning structure) to electrically connect to the feed source of the circuit board 820.

[0040] The electronic device 1 provided in the embodiment of the present application also includes a first sealant 610, which may be, but is not limited to, a sealant. The first sealant 610 is located in the receiving groove 20c and is arranged around the periphery of the radiator 310 to seal the front shell 20 and the radiator 310. For the convenience of description, the first sealant 610 may also be referred to as a first waterproof path (or waterproof path one). The first sealant 610 is located in the receiving groove 20c. Specifically, the first sealant 610 abuts against the periphery of the radiator 310 and abuts against the peripheral portion 220 to define the side wall of the receiving groove 20c to achieve a better sealing effect. In one embodiment, the waterproofness of the electronic device 1 can meet the requirements of waterproof grade IP68 or waterproof grade IP69.

[0041] Further, please refer again to Figure 4 and Figure 6 , Figure 6 for Figure 4Detailed identification diagram of the structure shown in . In the present embodiment, the receiving groove 20c includes a main body groove 20f and an overflow glue groove 20g. The main body groove 20f is connected to the first gap 20b. The overflow glue groove 20g is connected to the main body groove 20f and the through hole 20d. The first sealing member 610 is partially located in the main body groove 20f, and the other part is located in the overflow glue groove 20g. In the present embodiment, the main body groove 20f and the overflow glue groove 20g are arranged along the first direction D1. The size of the overflow glue groove 20g in the second direction D2 is smaller than the size of the main body groove 20f in the second direction D2. Wherein, the second direction D2 is perpendicular to the first direction D1. In addition, the peripheral portion 220 has a bottom wall surface 221 that defines the main body groove 20f, and a first inclined surface 222 and a second inclined surface 223 that define the overflow glue groove 20g. The first inclined surface 222 is connected to the bottom wall surface 221 and is inclined relative to the bottom wall surface 221. The second inclined surface 223 is disposed opposite to the first inclined surface 222, and is connected to the bottom wall surface 221 and is inclined relative to the bottom wall surface 221. From the arrangement direction of the body groove 20f and the overflow groove 20g, the distance between the first inclined surface 222 and the second inclined surface 223 gradually decreases.

[0042] In this embodiment, the receiving groove 20c includes a main body groove 20f and an overflow glue groove 20g. When the first sealing member 610 is a sealant, glue can be dispensed into the main body groove 20f (referred to as dispensing glue). The glue can flow from the main body groove 20f to the overflow glue groove 20g, which can reduce the generation of bubbles and enhance the sealing effect of the front shell 20 and the radiator 310.

[0043] In summary, the electronic device 1 provided in the embodiment of the present application, the radiator 310 of the antenna 30 in the electronic device 1 is a radiator 310 independent of the middle frame 10. Therefore, compared with the related art in which the radiator 310 is formed on an integrated middle frame structure, the cost of the antenna 30 of the electronic device 1 provided in the embodiment of the present application is lower. The middle frame 10 and the front shell 20 in the electronic device 1 in the embodiment of the present application are separate structures, and the structure of the middle frame 10 and the front shell 20 are designed separately in the embodiment of the present application. The middle frame 10 and the front shell 20 cooperate to form a first gap 20b, a receiving groove 20c, a through hole 20d and an accommodating space 20a. The radiator 310 is located in the first gap 20b, the receiving groove 20c, the through hole 20d and the accommodating space 20a. The electronic device 1 further includes a first seal 610, which is located in the receiving groove 20c and is arranged around the periphery of the radiator 310 to seal the front housing 20 and the radiator 310, so that the electronic device 1 has good waterproof performance. Therefore, the electronic device 1 provided in the embodiment of the present application can take into account both the waterproof performance and the cost of the electronic device 1. That is, the electronic device 1 provided in the embodiment of the present application has a lower cost and good waterproof performance.

[0044] For further information, see Figure 7 , Figure 7 for Figure 3 The line width schematic diagram of the receiving groove in the cross-sectional view of the electronic device shown in FIG. The line width W0 of the receiving groove 20c satisfies: 1.0 mm ≤ W0 ≤ 2.0 mm.

[0045] The line width of the receiving groove 20c is the size of the receiving groove 20c in the second direction D2.

[0046] The line width W0 of the receiving groove 20c may be, but is not limited to, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2.0 mm.

[0047] When the line width W0 of the receiving groove 20c is too small, when glue is dispensed into the receiving groove 20c to form the first seal 610, the glue may not be able to drip into the receiving groove 20c well, but drip to the outside of the receiving groove 20c, thereby resulting in a poor waterproof effect of the formed first seal 610. In other words, when the line width W0 of the receiving groove 20c is too small, there is not enough space for glue dispensing. When the line width W0 of the receiving groove 20c is too large, more glue is required, and the time to prepare the first seal 610 is longer, and the cost of the first seal 610 is higher. In addition, the excessively large line width W0 of the receiving groove 20c will also make the sealing effect of the first seal 610 on the radiator 310 and the front shell 20 worse.

[0048] To sum up, in the electronic device 1 provided in the embodiment of the present application, the line width W0 of the receiving groove 20c satisfies: 1.0mm≤W0≤2.0mm, which, on the one hand, allows the glue to be better dripped into the receiving groove 20c; on the other hand, it can reduce the time and cost of preparing the first seal 610, and can make the first seal 610 have a better sealing effect on the radiator 310 and the front shell 20.

[0049] Accordingly, in one embodiment, the line width W0' of the first sealing member 610 is equal to the line width W0 of the receiving groove 20c. The line width W0' of the first sealing member 610 satisfies: 1.0 mm ≤ W0' ≤ 2.0 mm.

[0050] For example, the line width W0′ of the first sealing member 610 may be, but is not limited to, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2.0 mm.

[0051] The line width W0 ′ of the first sealing member 610 satisfies: 1.0 mm≤W0 ′≤2.0 mm, so that the first sealing member 610 can have a better sealing effect on the radiator 310 and the front housing 20 .

[0052] For further information, see Figure 8 , Figure 8 Another embodiment provides Figure 1A cross-sectional schematic diagram of the electronic device shown in the figure along the II line. In this embodiment, the peripheral portion 220 has an outer peripheral side surface 220a facing away from the front shell body 210 and a bottom surface 220b connected to the outer peripheral side surface 220a by bending. Among them, the outer peripheral side surface 220a and the side frame 120 have the first gap 20b, and the opening of the receiving groove 20c is located at the outer peripheral side surface 220a, and a second gap 20e is provided between the bottom surface 220b of the peripheral portion 220 and the frame body 110. The electronic device 1 also includes a second sealing member 620. The second sealing member 620 is located in the second gap 20e to seal the front shell 20 and the middle frame 10.

[0053] The electronic device 1 provided in this embodiment further includes a second sealing member 620, which can be combined with the electronic device 1 provided in any of the above embodiments. The schematic diagram of the embodiment of the present application should not be understood as limiting the electronic device 1 provided in the embodiment of the present application.

[0054] The second sealing member 620 may be, but is not limited to, foam glue, rubber, glue, etc. Since the second sealing member 620 is located in the second gap 20e between the front housing 20 and the middle frame 10, when the second sealing member 620 is, but is not limited to, foam glue, rubber, glue, etc., the second sealing member 620 may also be referred to as waterproof adhesive. In this embodiment, the second sealing member 620 is foam glue as an example for illustration.

[0055] In this embodiment, the outer peripheral side surface 220a and the side frame 120 have the first gap 20b. As described above, the first sealing member is located in the receiving groove 20c and is arranged around the periphery of the radiator 310 to seal the front shell 20 and the radiator 310. Therefore, the first sealing member 610 can prevent external water vapor or dust from entering the receiving groove 20c from the first gap 20b formed by the outer peripheral side surface 220a and the side frame 120 and entering the accommodating space 20a through the through hole 20d.

[0056] In this embodiment, there is a second gap 20e between the bottom surface 220b of the peripheral portion 220 and the frame body 110, and the electronic device 1 further includes a second seal 620, which is located in the second gap 20e to seal the front shell 20 and the middle frame 10. Therefore, the second seal 620 can prevent external water vapor or dust from entering the accommodating space 20a from the second gap 20e formed between the bottom surface 220b of the peripheral portion 220 and the frame body 110. It can be seen that the electronic device 1 provided in the embodiment of the present application has a better waterproof effect.

[0057] As can be seen from the above introduction, the first seal 610 is located in the receiving groove 20c and is arranged around the periphery of the radiator 310 to seal the front shell 20 and the radiator 310. For the convenience of description, the first seal 610 can also be called a first waterproof path (or waterproof path one).

[0058] In this embodiment, the electronic device 1 further includes a second seal 620. The second seal 620 is located in the second gap 20e to seal the front housing 20 and the middle frame 10. For the convenience of description, the second seal 620 may also be referred to as a second waterproof path (or waterproof path 2).

[0059] In this embodiment, the electronic device 1 includes a first waterproof path and a second waterproof path, so that the electronic device 1 has a better waterproof effect.

[0060] See also Fig. 9 , Fig. 9 for Figure 8 The line width diagram of the second sealing member in the enlarged diagram of III in the figure. The line width W1 of the second sealing member 620 satisfies: 1.0 mm ≤ W1 ≤ 2.5 mm.

[0061] The line width W1 of the second seal 620 may also be referred to as the effective width of the second seal 620. The line width W1 of the second seal 620 may be, but is not limited to, 1.0 mm, or 1.1 mm, or 1.2 mm, or 1.3 mm, or 1.4 mm, or 1.5 mm, or 1.6 mm, or 1.7 mm, or 1.8 mm, or 1.9 mm, or 2.0 mm, or 2.1 mm, or 2.2 mm, or 2.3 mm, or 2.4 mm, or 2.5 mm.

[0062] When the line width of the second sealant 620 is small, the waterproof performance of the electronic device 1 at the second gap 20e formed by the front shell 20 and the middle frame 10 is weak; when the line width of the second sealant 620 is large, the waterproof performance of the electronic device 1 at the second gap 20e formed by the front shell 20 and the middle frame 10 is good, but it is not conducive to the layout of other devices in the electronic device 1.

[0063] In the electronic device 1 provided in the embodiment of the present application, the line width W1 of the second sealant 620 satisfies: 1.0mm≤W1≤2.5mm. On the one hand, this can enable the electronic device 1 to have a better waterproof effect at the second gap 20e formed by the front shell 20 and the middle frame 10; on the other hand, it can facilitate the layout of the second sealant 620 and other devices in the electronic device 1 in the electronic device 1.

[0064] Please continue reading Fig. 9 The second sealing member 620 is compressed and disposed in the second gap 20e, and the height H1 of the second sealing member 620 satisfies: 0.15mm≤H1≤0.4mm.

[0065] The second seal 620 is compressed and disposed in the second gap 20e. The height at which the second seal 620 is compressed and disposed in the second gap 20e is also referred to as the working height of the second seal 620, that is, the working height of the second seal 620.

[0066] When the second sealing member 620 is in a natural state, the height of the second sealing member 620 is named as an original height, and the original height is greater than the working height of the second sealing member 620 .

[0067] The so-called natural state of the second sealing member 620 refers to the state when the second sealing member 620 is not compressed and not stretched. The height of the second sealing member 620 in the natural state is greater than the height of the second sealing member 620 in compression. The height of the second sealing member 620 in the natural state is less than the height of the second sealing member 620 in stretching.

[0068] The second sealing member 620 is compressed and disposed in the second gap 20e, so that the second sealing member 620 can have a better waterproof effect.

[0069] The height H1 of the second sealing member 620 may be, but is not limited to, 0.15 mm, 0.20 mm, 0.25 mm, 0.30 mm, 0.35 mm, or 0.40 mm.

[0070] The second seal 620 is compressed and arranged in the second gap 20e, and the height H1 of the second seal 620 satisfies: 0.15mm≤H1≤0.4mm, which can further improve the sealing performance of the second seal 620, so that the electronic device 1 has a better waterproof effect in the second gap 20e formed by the front shell 20 and the middle frame 10.

[0071] Please also read Fig. 9 and Fig.10 , Fig.10 Schematic diagram of the original height of the second sealing member in a natural state. When the second sealing member 620 is in a natural state, the original height H0 satisfies: 0.2 mm ≤ H0 ≤ 0.5 mm, and H0> H1.

[0072] In this embodiment, the original height H0 of the second sealing member 620 in the natural state may be, but is not limited to, 0.2 mm, or 0.25 mm, or 0.30 mm, or 0.35 mm, or 0.40 mm, or 0.45 mm, or 0.50 mm.

[0073] The original height of the second sealing member 620 in a natural state is greater than the working height of the second sealing member 620 , that is, H0>H1.

[0074] The height H1 of the second seal 620 satisfies: 0.15mm≤H1≤0.4mm; the original height H0 of the second seal 620 in a natural state satisfies: 0.2mm≤H0≤0.5mm, and H0>H1; therefore, the second seal 620 can have a more appropriate compression amount when located at the second gap 20e, which can further improve the sealing performance of the second seal 620, so that the electronic device 1 has a better waterproof effect at the second gap 20e formed by the front shell 20 and the middle frame 10.

In this embodiment, the peripheral portion 220 further has a support surface 220c. The electronic device 1 further includes a display screen 40 and a third sealing member 630. The display screen 40 is disposed on one side of the support surface 220c and has a third gap 40a between the display screen 40 and the support surface 220c. The third sealing member 630 is disposed in the third gap 40a to seal the front housing 20 and the display screen 40.

[0076] The electronic device 1 further includes a display screen 40 and a third sealing member 630, which can be combined with the electronic device 1 provided in any of the above embodiments. In the schematic diagram of this embodiment, the electronic device 1 further includes a display screen 40 and a third sealing member 630, which can be combined with the electronic device 1 provided in the above embodiment as an example, which can be understood that it should not be understood as a limitation on the electronic device 1 provided in the present application.

[0077] The display screen 40 is a component for realizing a display function in the electronic device 1. The support surface 220c is away from the frame body 110 of the middle frame 10.

[0078] The third sealing member 630 may be, but is not limited to, foam glue, rubber, glue, etc. In this embodiment, the third sealing member 630 is glue. When the third sealing member 630 is glue, the third sealing member 630 may be formed by dispensing glue. The third sealing member 630 is disposed in the third gap 40a, the third sealing member 630 abuts against the support surface 220c, and the third sealing member 630 abuts against the surface of the display screen 40 facing the support surface 220c. In this way, the third sealing member 630 can achieve waterproofing of the third gap 40a of the electronic device 1.

[0079] In this embodiment, the electronic device 1 further includes a third sealing member 630, which is located in the third gap 40a to seal the display screen 40 and the front housing 20. For the convenience of description, the third sealing member 630 may also be referred to as a third waterproof path (or waterproof path three).

[0080] As can be seen from the above description, the electronic device 1 includes the first waterproof path. In this embodiment, the electronic device 1 includes the first waterproof path and the third waterproof path, which can make the electronic device 1 have a better waterproof effect.

[0081] In one embodiment, the display screen 40 has a display area and a non-display area. The display area is the area where the display screen 40 of the electronic device 1 displays, and the non-display area is arranged at the periphery of the display area. The non-display area is the area in the electronic device 1 that cannot display. The third sealing member 630 is arranged corresponding to the non-display area of ​​the display screen 40.

[0083] For example, the line width W2 of the third seal 630 may be, but is not limited to, 0.20 mm, or 0.25 mm, or 0.30 mm, or 0.35 mm, or 0.40 mm, or 0.45 mm, or 0.50 mm, or 0.51 mm, or 0.52 mm, or 0.53 mm, or 0.54 mm, or 0.55 mm, or 0.60 mm, or 0.65 mm.

[0084] When the line width of the third sealing member 630 is small, the sealing effect on the third gap 40a between the front shell 20 and the display screen 40 is not good; when the line width of the third sealing member 630 is large, on the one hand, it is not conducive to the assembly of the third sealing member 630 with other components in the electronic device 1, and it is easy to make the entire electronic device 1 wider.

[0085] In the electronic device 1 provided in the embodiment of the present application, the line width W2 of the third seal 630 satisfies: 0.20mm≤W2≤0.65mm. On the one hand, it has a better sealing effect on the third gap 40a between the front shell 20 and the display screen 40; on the other hand, it is conducive to the assembly of the third seal 630 with other components of the electronic device 1, so that the width of the electronic device is narrower.

[0086] It can be understood that in one embodiment, the electronic device 1 includes functional devices, including but not limited to earpieces and light sensors (abbreviated as light sensors). The line width of the third sealing member 630 corresponding to the functional devices can be but not limited to 0.45 mm.

[0087] For further information, please refer to Fig.12 , the third sealing member 630 satisfies: 0.3≤D≤0.5, wherein D=W2 / H2, H2 is the height of the third sealing member 630.

[0088] D=W2 / H2, that is, D represents the ratio of the width to the height of the third sealing member 630. When the third sealing member 630 is glue, D represents the ratio of the glue width to the glue height of the third sealing member 630 (hereinafter referred to as the glue width to glue height ratio). D can be, but is not limited to, 0.3, or 0.31, or 0.32, or 0.33, or 0.34, or 0.35, or 0.36, or 0.37, or 0.38, or 0.39, or 0.4, or 0.41, or 0.42, or 0.43, or 0.44, or 0.45, or 0.46, or 0.47, or 0.48, or 0.49, or 0.5.

[0089] The third sealing member 630 satisfies: 0.3≤D≤0.5, which can ensure that the third sealing member 630 has a good sealing effect on the one hand, and can also make the width of the third sealing member 630 narrower on the other hand. In other words, the third sealing member 630 satisfies: 0.3≤D≤0.5, which can ensure that the third sealing member 630 can still ensure good waterproofing even when it is narrow.
