Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an electronic equipment. Background Art

[0002] As users' requirements for the performance of electronic devices gradually increase, the waterproof performance of electronic devices has become an important design consideration. In the related art, the housing assembly of the electronic device includes a first housing and a second housing. The second housing is fixed to the circumferential inner side of the first housing. It is understandable that there will inevitably be an assembly gap between the first housing and the second housing. The assembly gap will cause liquid to penetrate into the interior of the electronic device, which is undesirable because it may damage the electronic components inside the electronic device. Therefore, in the related art, the waterproof effect of the electronic device is poor and needs to be further improved. Utility Model Content

[0003] The present application provides an electronic device, which can help improve the waterproof effect of the electronic device.

[0004] In order to achieve the above objectives, this application adopts the following technical solutions:

[0005] The present application provides an electronic device, comprising: a first shell, a second shell, a waterproof component and a plurality of antennas. The second shell is fixed to the inner side of the first shell in the circumferential direction, and the second shell comprises a side frame; the waterproof component is sealed between the side frame and the first shell; a plurality of antennas are fixed between the side frame and the first shell, and the plurality of antennas are spaced apart and distributed in the circumferential direction of the first shell, a first gap is formed between two adjacent antennas, and a sealing component is provided in the first gap; wherein, when the plurality of antennas are stacked between the waterproof component and the first shell, the sealing component is connected to both the first shell and the waterproof component; when the plurality of antennas are stacked between the waterproof component and the side frame, the sealing component is connected to both the side frame and the waterproof component.

[0006] In the electronic device provided in the present application, since a sealant is provided at the first gap, when multiple antennas are located between the waterproof member and the first shell, the sealant is connected to both the first shell and the waterproof member; when multiple antennas are located between the waterproof member and the side frame, the sealant is connected to both the side frame and the waterproof member. When multiple antennas are located between the waterproof member and the first shell, the sealant can block the first gap and the channel surrounded by the waterproof member and the first shell. When multiple antennas are located between the waterproof member and the side frame, the sealant can block the first gap and the channel surrounded by the waterproof member and the side frame. Therefore, liquid can be blocked from entering the interior of the electronic device, thereby improving the waterproof effect of the electronic device.

[0007] In a possible implementation, the material of the sealing member is curing glue. Thus, on the one hand, since the initial state of the curing glue is liquid, the difficulty of assembling the sealing member into the first gap can be reduced. On the other hand, since the stable structure formed by the curing glue during the hardening process can be tightly filled and tightly bonded to the surface joined to the curing glue, the sealing member can more effectively prevent the penetration of liquid and maintain a long-term sealing effect.

[0008] In a possible implementation, the waterproof member is a sealing foam, so that the waterproof member has a simple structure and is easy to assemble.

[0009] In a possible implementation, the antenna is a flexible circuit board. Thus, on the one hand, the antenna has a simple structure and is easy to assemble; on the other hand, the antenna has a low manufacturing cost, which is conducive to reducing the cost of the entire device.

[0010] In one possible implementation, at least one antenna is a first antenna. That is, some antennas may be first antennas, or all antennas may be first antennas. At least one end of the first antenna along the circumference of the first shell has a positioning notch. That is, one end of the first antenna along the circumference of the first shell may have a positioning notch, or both ends of the first antenna along the circumference of the first shell may have positioning notches. It is necessary to explain that when there are multiple first antennas, the number of upper positioning notches of each first antenna may be consistent or inconsistent. The sealant located on the same side of the first antenna as the positioning notch is also filled in the positioning notch. In this way, on the one hand, it is easy to identify the assembly position of the sealant, which is beneficial to improve the assembly efficiency of the sealant; on the other hand, when the sealant is a curing glue, it can also reduce the difficulty of filling the curing glue into the first gap.

[0011] In a possible implementation, the first housing includes a first middle plate and a first frame, the first frame is arranged around the edge of the first middle plate; the first frame is arranged around the side frame; a part of each antenna is located between the inner circumference of the first frame and the outer circumference of the side frame, and another part of each antenna is located between the first middle plate and the side frame. In this way, it is beneficial to increase the space for assembling antennas in the electronic device, and further to make the antenna more stably installed in the electronic device. At the same time, it is also convenient for the part of the antenna located between the inner circumference of the first frame and the outer circumference of the side frame to send and receive signals to the outside of the electronic device.

[0012] In a possible implementation, the side frame includes a first side panel and a second side panel that are arranged opposite to each other, and a third side panel and a fourth side panel that are arranged opposite to each other, and the first frame is formed by connecting the first side panel, the third side panel, the second side panel, and the fourth side panel end to end and enclosing them in sequence. At least one antenna portion is disposed between the first side panel and the first shell, between the second side panel and the first shell, between the third side panel and the first shell, and between the fourth side panel and the first shell. In this way, the radiation signal of the antenna can cover the entire electronic device, and the signal quality received and transmitted by the antenna can be improved.

[0013] In a possible implementation, the first gap includes a first gap section located at the first middle plate, and the sealing member is located at the first gap section. Thus, when the sealing member is a curing glue, it is convenient to fill the curing glue into the first gap.

[0014] In one possible implementation, the electronic device also includes a water-proof seal, which is located on the inner peripheral side of the side frame, abuts against the waterproof component and partially fills the first gap; wherein the portion of the water-proof seal located in the first gap is located on the side of the seal close to the interior of the first shell.

[0015] In this way, on the basis of the sealing member, a water-proof sealing member is provided to perform secondary waterproofing, thereby further improving the waterproofing effect of the electronic device.

[0016] In a possible implementation, the water-proof sealing member is a rubber member, a silicone member or a sealing foam, which is low in cost and easy to assemble.

[0017] In a possible implementation, there are multiple first gaps, and the waterproof seal includes multiple independent and spaced-apart sub-waterproof seals, and the multiple sub-waterproof seals correspond one-to-one to the multiple first gaps, and each sub-waterproof seal partially fills the corresponding first gap. In this way, on the one hand, the number of sub-waterproof seals can be adaptively adjusted according to the number of first gaps. On the other hand, since the multiple sub-waterproof seals are independent and spaced-apart, when a sub-waterproof seal needs to be replaced, it is not necessary to disassemble all the sub-waterproof seals, thereby facilitating replacement. On the other hand, the manufacturing cost of the waterproof seal can be reduced.

[0018] In a possible implementation, the second shell includes a second middle plate, and the side frame is arranged around the edge of the second middle plate; the second middle plate is stacked and spaced apart from the first middle plate; the electronic device also includes a water-proof seal, the water-proof seal is located on the inner peripheral side of the side frame and between the first middle plate and the second middle plate, the water-proof seal abuts against the waterproof member and partially fills the first gap; wherein the part of the sealing structure of the water-proof seal located in the first gap is located on the side of the seal close to the inside of the first shell. In this way, the assembly of the water-proof seal is facilitated.

[0019] In a possible implementation, the waterproof component includes a first waterproof section, which is located on the side facing the inner peripheral surface of the side frame; the waterproof seal sealing structure has a step portion, which has a first step surface and a second step surface, the second step surface is connected to the first step surface and there is an angle between the two, the first step surface faces the first middle plate, the first waterproof section overlaps the first step surface and abuts against the second step surface, and the part of the second step surface on the step portion is filled in the first gap. In this way, while ensuring that the waterproof seal can be filled into the first gap and block the opening connecting the liquid inlet channel and the installation space, the area of ​​the support surface for installing the waterproof seal can also be increased, so that the waterproof seal can be installed more stably.

[0020] In a possible implementation, a circuit board assembly is further included, the circuit board assembly is arranged on the surface of the second middle plate facing the first middle plate, and the waterproof seal seal structure abuts between the circuit board assembly and the first middle plate. In this way, the waterproof seal can be installed inside the electronic device more stably.

[0021] In a possible implementation, the electronic device further includes a circuit board assembly, which is disposed on the inner circumference of the side frame and between the first shell and the second shell, and a radio frequency chip is disposed on the circuit board assembly, and the radio frequency chip is electrically connected to the plurality of antennas. In this way, the first shell and the second shell can be used to protect the circuit board assembly and the radio frequency chip on the circuit board assembly, thereby increasing the service life of the circuit board assembly and the radio frequency chip, and the structural layout is relatively reasonable.

This embodiment and the embodiments below are exemplified by taking the electronic device 100 as a handheld device mobile phone with wireless communication function. The electronic device 100 is roughly in the shape of a rectangular plate. Based on this, in order to facilitate the description of the embodiments below, an XYZ coordinate system is established, and the width direction of the electronic device 100 is specifically defined as the X-axis direction, the length direction of the electronic device 100 is the Y-axis direction, and the thickness direction of the electronic device 100 is the Z-axis direction. It can be understood that the coordinate system of the electronic device 100 can be flexibly set according to actual needs, and no specific limitation is made here. In some other embodiments, the shape of the electronic device 100 can also be a square plate, a circular plate, an elliptical plate, etc., which are not specifically limited here.

The embodiment of the present application is described by taking a straight-screen flat screen mobile phone as an example.

[0041] See also Figure 1 Combined with Figure 2 , Figure 2 for Figure 1 An exploded view of the electronic device 100 is shown. The electronic device 100 includes a screen 1 , a housing assembly 2 , a circuit board assembly 3 and a plurality of antennas 4 .

[0042] Understandably, Figure 1 and Figure 2 The electronic device 100 is only schematically shown to include some components, and the actual shapes, actual sizes, actual positions and actual structures of these components are not subject to Figure 1 and Figure 2 In some other embodiments, the electronic device 100 may not include the screen 1.

[0043] The screen 1 is used to display images, videos, etc. The screen 1 includes a light-transmitting cover plate 11 and a display screen 12. The light-transmitting cover plate 11 and the display screen 12 are stacked and fixedly connected. The light-transmitting cover plate 11 is mainly used to protect the display screen 12 and prevent dust. The material of the light-transmitting cover plate 11 includes but is not limited to glass.

[0044] The display screen 12 may be a flexible display screen or a rigid display screen. For example, the display screen 12 may be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MIL-E) display screen, a micro organic light-emitting diode (MIL-E) display screen, a micro organic light-emitting diode (MIL-E) display screen, a quantum dot light-emitting diode (QLED) display screen, a liquid crystal display (LCD), and the like.

[0045] The screen 1 is fixed to the housing assembly 2. The connection method between the screen 1 and the housing assembly 2 includes but is not limited to gluing.

[0046] The housing assembly 2 is used to protect the internal electronic components of the electronic device 100. Figure 2 The housing assembly 2 includes a first housing 21 , a back cover 23 and a second housing 22 .

[0047] In order to achieve lightweight electronic device 100 and reduce the manufacturing cost of electronic device 100, the material of first housing 21 and second housing 22 may be plastic. Of course, the present application is not limited thereto, in other embodiments, the material of first housing 21 and second housing 22 may also be ceramic, glass or metal.

[0048] See also Figure 2 and Figure 3 , Figure 3 for Figure 1 The schematic diagram of the cross-sectional structure of the electronic device 100 at the AA line is shown. The first housing 21 includes a first middle plate 212 and a first frame 211. The first frame 211 is arranged around the periphery of the first middle plate 212. For example, the first middle plate 212 can be fixed to the first frame 211 by screw connection, clamping, etc.; or the first middle plate 212 and the first frame 211 are an integrally formed structure.

[0049] The back cover 23 and the first middle plate 212 are stacked. The first frame 211 is fixed on the back cover 23, and the first frame 211 is arranged around the periphery of the back cover 23. Exemplarily, the first frame 211 can be fixedly connected to the back cover 23 by bonding, clamping, etc.; or the first frame 211 and the back cover 23 are an integrally formed structure, that is, the first frame 211 and the back cover 23 are an integral structure. The material of the back cover 23 includes but is not limited to plastic, metal or plain leather.

[0050] See also Figure 3 , the second shell 22 is fixed to the circumferential inner side of the first shell 21. Specifically, the second shell 22 includes a side frame 221 and a second middle plate 222. The side frame 221 is arranged around the edge of the second middle plate 222. The connection method between the side frame 221 and the second middle plate 222 can be designed with reference to the connection method between the first frame 211 and the first middle plate 212, which will not be repeated here.

[0051] A portion of the side frame 221 is embedded in the first frame 211. It is understandable that in other embodiments, the entire side frame 221 may be embedded in the first frame 211. It is sufficient as long as the first frame 211 is arranged around the side frame 221.

[0052] The second middle plate 222 is stacked and spaced apart from the first middle plate 212 to form an installation space M. The second middle plate 222 is located on the side of the first middle plate 212 that is away from the back cover 23. The screen 1 is fixedly connected to the surface of the second middle plate 222 that is away from the first middle plate 212. The installation space M is used to accommodate the internal electronic components of the electronic device 100 (for example: circuit board assembly 3, battery, camera module, etc.). It can be understood that in other embodiments, when a accommodating space is defined between the first middle plate 212 and the back cover 23, the internal electronic components of the electronic device 100 can also be arranged in the accommodating space defined between the first middle plate 212 and the back cover 23.

[0053] The circuit board assembly 3 is used to set up electronic components and realize electrical connection between various electronic components. Figure 3 The circuit board assembly 3 is disposed on the inner circumference of the side frame 221 and is located between the first housing 21 and the second housing 22. Specifically, the circuit board assembly 3 is disposed on the surface of the second middle plate 222 facing the first middle plate 212.

[0054] Please continue reading Figure 2 and Figure 3 In some embodiments, the circuit board assembly 3 may include a first circuit board 31 and a second circuit board 32. The first circuit board 31 and the second circuit board 32 are arranged opposite to each other in the Y-axis direction, and the first circuit board 31 and the second circuit board 32 are stacked with the second middle board 222.

[0055] The first circuit board 31 can be used for integrated chips. The chip can be, for example, an application processor (AP), a double data rate synchronous dynamic random access memory (DDR), a universal flash storage (UFS), a radio frequency chip 311, etc. The first circuit board 31 is electrically connected to the display screen 12, and the first circuit board 31 is used to control the display screen 12 to display images or videos.

[0056] The first circuit board 31 can be a hard circuit board, a flexible circuit board, or a hard-soft circuit board. The first circuit board 31 can be a FR- dielectric board, a Rogers R dielectric board, or a mixed dielectric board of FR- and R, etc. Here, FR- is a code for a flame retardant material grade, and the R dielectric board is a high-frequency board.

[0057] The second circuit board 32 is used to integrate electronic components such as universal serial bus (USB) devices and vibrators.

[0058] The second circuit board 32 can be a hard circuit board, a flexible circuit board, or a hard-soft circuit board. The second circuit board 32 can be a FR-4 dielectric board, a Rogers dielectric board, a mixed dielectric board of FR-4 and Rogers, and so on.

[0059] The second circuit board 32 is electrically connected to the first circuit board 31 through a connection structure to achieve data and signal transmission between the second circuit board 32 and the first circuit board 31. The connection structure includes but is not limited to a flexible printed circuit (FPC), a wire, an enameled wire, or a structure formed by weaving a wire and a flexible material.

[0060] It is understandable that there is inevitably an assembly gap Q between the first shell 21 and the second shell 22. Since the assembly gap Q connects the installation space M with the environmental space outside the shell assembly 2. Therefore, the assembly gap Q may cause liquid to penetrate into the first shell 21, which is undesirable because it may damage the internal electronic components of the electronic device 100. Therefore, the shell assembly 2 needs to be sealed. Please refer to Figure 3 In some embodiments, the electronic device 100 further includes a waterproof member 5 , which is sealed between the side frame 221 and the first housing 21 . The waterproof member 5 is annular and is disposed along a periphery of the side frame 221 .

[0061] In some embodiments, the waterproof member 5 is a sealing foam. In this way, the cost is low and it is easy to assemble. In other embodiments, the waterproof member 5 can also be a rubber ring or a silicone ring.

[0062] See also Figure 3 , multiple antennas 4 are electrically connected to the RF chip 311 on the first circuit board 31 to transmit the RF signal from the RF chip 311 to the external space in the form of electromagnetic waves to achieve signal transmission; or multiple antennas 4 can also receive electromagnetic waves from the external space and convert the electromagnetic waves into RF signals and transmit them to the RF chip 311 to achieve signal reception.

[0063] In some embodiments, the RF chip 311 includes a transmitting path and a receiving path. The transmitting path includes devices such as a power amplifier and a filter, and the signal is amplified and filtered by the power amplifier and the filter, and then transmitted to the antenna 4 and transmitted to the outside through the antenna 4; the receiving path includes devices such as a low-noise amplifier and a filter, and the external signal received by the antenna 4 is amplified and filtered by the low-noise amplifier and the filter, and then transmitted to the RF chip 311, so that the electronic device 100 communicates with the external signal through the RF chip 311 and the antenna 4.

[0064] Antenna 4 includes but is not limited to omnidirectional antennas and directional antennas. An omnidirectional antenna is an antenna that radiates signals in all directions of the antenna like a spherical transmitting source, that is, the signal radiation intensity in all directions of the antenna is the same at 360° to achieve the best communication effect. A directional antenna is an antenna that radiates signals in a specific direction.

[0065] Exemplarily, antenna 4 can be a Wi-Fi antenna, and electronic device 100 can achieve short-range communication through antenna 4 to achieve functions such as D2D (device-to-device communication), WiFi screen projection, and WiFi proximity discovery. Antenna 4 can operate in the 2.4G frequency band (frequency in the range of 2.4GHz to 2.5GHz) and / or the 5G frequency band (frequency in the range of 5GHz-6GHz) for WLAN communication. Understandably, both the 2.4G frequency band and the 5G frequency band are used for short-range wireless communication technology. The 2.4G frequency band has a narrow bandwidth, a low frequency, a strong ability to penetrate walls, and a large communication range; the 5G frequency band has a wide bandwidth, a high frequency, and a fast transmission speed. Antenna 4 can select a suitable frequency band according to the working environment to adapt to a variety of application environments and improve the communication performance of the electronic device 100.

[0066] It should be noted that the multiple antennas 4 can work independently of each other or in combination. Each antenna 4 in the electronic device 100 can be used to cover a single or multiple communication frequency bands. Different antennas 4 can also be reused to improve the utilization of the antennas 4.

[0067] In some embodiments, the antenna 4 is a flexible circuit board. That is, a flexible circuit board is provided inside the electronic device 100, and the flexible circuit board is electrically connected to the above-mentioned radio frequency chip 311, so that the flexible circuit board is used as an antenna. In this way, on the one hand, the structure of the antenna 4 is simple and easy to assemble; on the other hand, the manufacturing cost of the antenna 4 is low, which is conducive to reducing the cost of the whole machine. It is understandable that in other embodiments, the antenna 4 can also be a metal sheet.

[0068] See also Figure 3 In some embodiments, the plurality of antennas 4 are fixed between the first housing 21 and the side frame 221. The plurality of antennas 4 are arranged at intervals in the circumferential direction of the first housing 21. For details, please refer to Figure 2 The side frame 221 is in a rectangular ring shape, and the side frame 221 includes a first side plate 2211 and a second side plate 2212 that are arranged opposite to each other, and a third side plate 2213 and a fourth side plate 2214 that are arranged opposite to each other. The first frame 211 is formed by connecting the first side plate 2211, the third side plate 2213, the second side plate 2212, and the fourth side plate 2214 end to end in sequence and enclosing them. It can be understood that in other embodiments, the side frame 221 can also be in a circular ring, an elliptical ring, etc.

[0069] At least a portion of at least one antenna 4 is disposed between the first side plate 2211 and the first housing 21, between the second side plate 2212 and the first housing 21, between the third side plate 2213 and the first housing 21, and between the fourth side plate 2214 and the first housing 21. In this way, the radiation signal of the antenna 4 can cover the entire perimeter of the electronic device 100, thereby improving the quality of signals received and transmitted by the antenna 4.

[0070] For example, an antenna 4 is disposed between the first side plate 2211 and the first shell 21, between the second side plate 2212 and the first shell 21, between the third side plate 2213 and the first shell 21, and between the fourth side plate 2214 and the first shell 21. For another example, an antenna 4 is disposed between the first side plate 2211 and the first shell 21, between the second side plate 2212 and the first shell 21, and a portion of an antenna 4 is disposed between the third side plate 2213 and the first shell 21, and between the fourth side plate 2214 and the first shell 21. For another example, two antennas 4 are disposed between the first side plate 2211 and the first shell 21, between the second side plate 2212 and the first shell 21, between the third side plate 2213 and the first shell 21, and between the fourth side plate 2214 and the first shell 21.

[0071] Of course, the present application is not limited thereto, and in other embodiments, at least one antenna 4 may be disposed between a portion of the side panels of the side frame 221 and the first housing 21. For example, at least one antenna 4 may be disposed only between the first side panel 2211 and the first housing 21; or at least one antenna 4 may be disposed only between the first side panel 2211 and the first housing 21, and between the third side panel 2213 and the first housing 21.

[0072] In order to achieve clearance between multiple antennas 4 and reduce the difficulty and cost of assembling antennas 4. Figure 4 , Figure 4 for Figure 2 Schematic diagram of partial assembly of antenna 4 and first housing 21 in the electronic device shown. In some embodiments, multiple antennas 4 are spaced apart and distributed in the circumferential direction of first housing 21, and a first gap 41 (also called antenna gap) is formed between two adjacent antennas 4. The width d of the first gap 41 is generally greater than or equal to 0.2 mm and less than or equal to 0.8 mm. Exemplarily, the width of the first gap 41 can be 0.3 mm, 0.35 mm, 0.43 mm, 0.5 mm, 0.55 mm, 0.6 mm or 0.7 mm, etc.

[0073] The first slit 41 includes a first slit section 411 and a second slit section 412. The first slit section 411 is located on the first middle plate 212, and the second slit section 412 is located on the inner circumference of the first frame 211. For details, please refer to Figure 3 and Figure 4 , a portion of each antenna 4 is located between the inner circumference of the first frame 211 and the outer circumference of the side frame 221, and the portions of two adjacent antennas 4 located between the inner circumference of the first frame 211 and the outer circumference of the side frame 221 are spaced apart to form the above-mentioned second slot section 412. Another portion of each antenna 4 is located between the first middle plate 212 and the side frame 221, and the portions of two adjacent antennas 4 located between the first middle plate 212 and the side frame 221 are spaced apart to form the above-mentioned first slot section 411. In this way, it is beneficial to increase the space for assembling the antenna 4 of the electronic device 100, and further to facilitate the antenna 4 to be installed in the electronic device 100 more stably. At the same time, it is also convenient for the portion of the antenna 4 located between the inner circumference of the first frame 211 and the outer circumference of the side frame 221 to send and receive signals to the outside of the electronic device 100.

[0074] Of course, the present application is not limited to this. In other embodiments, the antenna 4 as a whole can be located between the inner circumference of the first frame 211 and the outer circumference of the side frame 221 , or between the first middle plate 212 and the side frame 221 .

[0075] On this basis, the antenna 4 is fixed on the surface of the first shell 21 facing the second shell 22. In this way, the antenna 4 can be closer to the outside space, improving the quality of the signal received and sent by the antenna 4. Exemplarily, the antenna 4 can be fixed on the surface of the first shell 21 facing the second shell 22 by gluing. This is conducive to improving the sealing between the antenna 4 and the first shell 21. It can be understood that in other embodiments, the antenna 4 can be fixed on the surface of the side frame 221 facing the first shell 21.

[0076] To further improve the quality of antenna 4's signal reception and transmission. Figure 5 Combined with Figure 6 , Figure 5 for Figure 3 An enlarged view of the circled portion of the structure shown at B; Figure 6 for Figure 5 Schematic diagram of partial assembly of the waterproof component 5 and the antenna 4 with the first shell 21 in the structure shown. In some embodiments, the waterproof component 5 and the antenna 4 are stacked. Specifically, when the antenna 4 is fixed on the surface of the first shell 21 facing the second shell 22, the waterproof component 5 is stacked between the antenna 4 and the side frame 221. When the antenna 4 is fixed on the surface of the side frame 221 facing the first shell 21, the waterproof component 5 is stacked between the antenna 4 and the first shell 21.

[0077] It is understandable that at this time, the waterproof member 5 covers the opening of the first gap 41 toward the waterproof member 5. Since the size of the first gap 41 is small, considering the difficulty of processing and manufacturing the waterproof member 5 and the difficulty of assembly, the waterproof member 5 cannot be used to fill the first gap 41, so when multiple antennas 4 are located between the waterproof member 5 and the first shell 21, the first gap 41, the waterproof member 5 and the first shell 21 will form a liquid inlet channel. When multiple antennas 4 are located between the waterproof member 5 and the side frame 221, the first gap 41, the waterproof member 5 and the side frame 221 will form a liquid inlet channel.

[0078] Since the first gap 41 ( Figure 5 (not shown) the assembly gap Q is connected to the installation space M, so the liquid inlet channel is connected to the assembly gap Q to form a liquid inlet path K. The liquid inlet path K may cause liquid to penetrate into the interior of the first housing 21, resulting in waterproof failure.

[0079] In order to solve the problem that liquid enters the first housing 21 through the liquid inlet path K, causing waterproof failure. Figure 7 Combined with Figure 8 , Figure 7 A schematic diagram of a partial structure of a housing assembly 2 provided in some other embodiments of the present application; Figure 8 for Figure 7 The schematic diagram of partial assembly of the housing assembly waterproof part 5 and the antenna 4 with the first housing 21 is shown. The first gap 41 ( Figure 7 A sealing member 6 is provided inside the first housing 21 (not shown). When multiple antennas 4 are located between the waterproof member 5 and the first housing 21, the sealing member 6 is connected to both the first housing 21 and the waterproof member 5, so that the sealing member 6 is used to block the passage surrounded by the first gap 41, the waterproof member 5 and the first housing 21; when multiple antennas 4 are located between the waterproof member 5 and the side frame 221, the sealing member 6 is connected to both the side frame 221 and the waterproof member 5, so that the sealing member 6 is used to block the passage surrounded by the first gap 41, the waterproof member 5 and the side frame 221. In this way, liquid can be blocked from entering the interior of the first housing 21, and the waterproof effect of the electronic device 100 can be improved.

[0080] It should be noted that the seal 6 can block a local area of ​​the liquid inlet channel or the entire liquid inlet channel. On this basis, the seal 6 can also be entirely located in the liquid inlet channel, or partially located in the liquid inlet channel and partially located outside the liquid inlet channel.

[0081] In some embodiments, the material of the sealant 6 is a curing glue. Exemplarily, the curing glue can be an ultraviolet (UV) glue, a heat curing glue, or a single-component glue. In this way, on the one hand, since the initial state of the curing glue is liquid, the difficulty of assembling the sealant 6 into the first gap 41 can be reduced. On the other hand, since the stable structure formed by the curing glue during the curing process can be tightly filled and tightly bonded to the surface joined to the curing glue. Therefore, the sealant 6 can be more effectively prevented from the penetration of liquid and maintain a long-term sealing effect.

[0082] Of course, the present application is not limited thereto, and in other embodiments, the sealing member 6 may also be a rubber or silicone plug or other structures.

[0083] See also Fig. 9 , Fig. 9 for Figure 8 The structure shown is a schematic diagram of the structure of the hidden waterproof member 5. In some embodiments, the seal 6 is located at the first gap section 411. Since the first middle plate 212 is generally flat, the seal 6 is arranged in the first gap section 411 located at the first middle plate 212. When the seal 6 is a curing glue, it is convenient to fill the curing glue into the first gap 41. Of course, the present application is not limited to this. In other embodiments, the seal 6 can also be located in the second gap section 412.

[0084] See also Fig. 9 In some embodiments, at least one antenna 4 is a first antenna 42. That is, one or more of the multiple antennas 4 may be the first antenna 42, or all of the antennas 4 may be the first antenna 42.

[0085] At least one end of the first antenna 42 along the circumference of the first shell 21 has a positioning notch 421. That is, the first antenna 42 may have a positioning notch 421 at one end along the circumference of the first shell 21, or both ends of the first antenna 42 along the circumference of the first shell 21 may have positioning notches 421. It is necessary to explain that when there are multiple first antennas 42, the number of upper positioning notches 421 of each first antenna 42 may be the same or different.

[0086] The sealing member 6 located on the same side of the first antenna 42 as the positioning notch 421 is also filled in the positioning notch 421. In this way, on the one hand, it is easy to identify the assembly position of the sealing member 6, thereby facilitating the improvement of the assembly efficiency of the sealing member 6; on the other hand, when the sealing member 6 is a curing adhesive, it can also reduce the difficulty of filling the curing adhesive into the first gap 41.

[0087] See also Fig.10 , Fig.10 Schematic diagram of a part of the housing assembly 2 provided in some embodiments of the present application. In some embodiments, the electronic device 100 further includes a watertight seal 7. The watertight seal 7 is located on the inner circumference of the side frame 221. The watertight seal 7 abuts against the waterproof member 5 and partially fills the first gap 41 ( Fig.10 (not shown in the figure), the portion of the watertight seal 7 located in the first gap 41 is located on the side of the seal 6 close to the interior of the first shell 21.

[0088] In this way, the waterproof seal 7 is provided on the basis of the seal 6 to achieve secondary waterproofing, thereby further improving the waterproofing effect of the electronic device 100 .

[0089] In some embodiments, the water-proof seal 7 is a rubber piece, a silicone piece or a sealing foam. In this way, the water-proof seal 7 has a simple structure and is easy to assemble.

[0090] See also Fig.11 , Fig.11 for Fig.10 The schematic diagram of the assembly of the antenna 4 and the waterproof seal 7 in the shell assembly 2 is shown. In some embodiments, there are multiple first gaps 41, and the waterproof seal 7 includes multiple independent and spaced-apart sub-waterproof seals 71, and the multiple sub-waterproof seals 71 correspond to the multiple first gaps 41 one by one, and each sub-waterproof seal 71 is partially filled in the corresponding first gap 41. In this way, on the one hand, the number of sub-waterproof seals 71 can be adaptively adjusted according to the number of first gaps 41. On the other hand, since the multiple sub-waterproof seals 71 are independent and spaced-apart from each other, when a certain sub-waterproof seal 71 needs to be replaced, it is not necessary to disassemble all the sub-waterproof seals 71, thereby facilitating replacement. On the other hand, the manufacturing cost of the waterproof seal 7 can be reduced.

[0091] Of course, the present application is not limited thereto. In other embodiments, the watertight seal 7 may also be formed in a ring shape. The watertight seal 7 includes an annular body and a plurality of sub-watertight seals 71 disposed on the annular body.

[0092] See also Fig.10 On the basis of the above embodiment, the water-proof seal 7 abuts between the circuit board assembly 3 and the first middle plate 212. Specifically, when the first gap 41 is only opposite to the first circuit board 31 in the Z-axis direction, the water-proof seal 7 abuts only between the first circuit board 31 and the first middle plate 212; when the first gap 41 is only opposite to the second circuit board 32 in the Z-axis direction, the water-proof seal 7 abuts only between the second circuit board 32 and the first middle plate 212; when the first gap 41 is opposite to both the second circuit board 32 in the Z-axis direction and the second circuit board 32 in the Z-axis direction, the water-proof seal 7 abuts between the first circuit board 31 and the first middle plate 212 and between the second circuit board 32 and the first middle plate 212. In this way, the water-proof seal 7 can be more stably installed inside the electronic device 100.

[0093] It is understandable that in other examples, the waterproof seal 7 may also abut between the second middle plate 222 and the first middle plate 212 , as long as the waterproof seal 7 is located between the first middle plate 212 and the second middle plate 222 .

[0094] See also Fig.10 In some embodiments, the waterproof member 5 includes a first waterproof section 51, and the first waterproof section 51 is located on the side toward which the inner circumference of the side frame 221 faces. The waterproof seal 7 has a step portion 72, and the step portion 72 has a first step surface 721 and a second step surface 722, and the second step surface 722 is connected to the first step surface 721 and has an angle therebetween. The specific value of the angle depends on actual needs, and this application does not limit it here.

[0095] The first step surface 721 faces the first middle plate 212 . The first waterproof section 51 overlaps the first step surface 721 and abuts against the second step surface 722 . The second step surface 722 on the step portion 72 is filled in the first gap 41 .

[0096] In this way, while ensuring that the water-proof seal 7 can be filled into the first gap 41 and the opening connecting the liquid inlet channel and the installation space M is blocked, the area of ​​the supporting surface for installing the water-proof seal 7 can also be increased, making the installation of the water-proof seal 7 more stable.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
