Description

Technical Field

[0001] This application relates to the technical field of electronic products, and particularly to an electronic device. Background Art

[0002] With the increase in the frequency bands supported by electronic devices and the requirements for transmitting or receiving signals, the requirement for the radiation intensity of antennas is getting higher and higher. However, in current electronic devices, the antenna assembly is rather troublesome and the radiation intensity is weak. Summary of the Invention

[0003] This application provides an electronic device, in which the antenna does not need to be assembled and has a relatively strong radiation intensity.

[0004] This application provides an electronic device, including: a housing, a first button, a second button, a first circuit board, a second circuit board, an antenna, and a device circuit board; the antenna includes a radiator and a feeding part, and both the radiator and the feeding part are integrally formed on the housing; the first button, the second button, the first circuit board, the second circuit board, the feeding part, and the device circuit board are all arranged inside the housing.

[0005] The electronic device can be a foldable mobile phone, which includes a first housing and a second housing that are rotatably connected. The above-mentioned housing can be the first housing or the second housing. The electronic device can also be a straight mobile phone.

[0006] The first button can be a volume increase button, the second button can be a volume decrease button, and the device circuit board can integrate a radio frequency chip and a control chip. The radio frequency chip is used to be electrically connected to the feeding part. The signal emitted by the radio frequency chip can be transmitted to the feeding part, and then the feeding part transmits the signal to the radiator, and the radiator emits the signal, so that the electronic device can emit a signal. The signal received by the radiator can be transmitted to the feeding part, and the signal received by the feeding part can be transmitted to the radio frequency chip, so that the electronic device can receive a signal.

[0007] The control chip is used to be electrically connected to the first button through the first circuit board and to the second button through the second circuit board. After pressing the first button, the control chip can control the volume of the electronic device to increase, and after pressing the second button, the control chip can control the volume of the electronic device to decrease.

[0008] Along a first direction, two sides of the first circuit board are respectively connected to the first button and the device circuit board, and two sides of the second circuit board are respectively connected to the second button and the device circuit board; along a second direction perpendicular to the first direction, the first button and the second button are arranged at intervals, the power feeding part is arranged between the first button and the second button and is electrically connected to the device circuit board, the first circuit board and the power feeding part are arranged at intervals, and the second circuit board and the power feeding part are arranged at intervals.

[0009] Thus, at least part of the power feeding part is exposed relative to the first circuit board, and at least part of the power feeding part is also exposed relative to the second circuit board. Furthermore, it is possible to avoid the first circuit board from affecting the signal radiation intensity of the power feeding part, and avoid the second circuit board from affecting the signal radiation intensity of the power feeding part, so that the signal intensity radiated by the power feeding part is relatively strong, and thus the radiation intensity of the antenna can be enhanced.

[0010] In some embodiments, along the second direction, the interval between the first circuit board and the power feeding part is at least 0.8 mm, and the interval between the second circuit board and the power feeding part is at least 0.8 mm. Thus, there is sufficient clearance area between the first circuit board and the power feeding part, and there is also sufficient clearance area between the second circuit board and the power feeding part, so that the radiation performance of the power feeding part can be better exerted.

[0011] In some embodiments, the housing includes a frame and a support member. The frame surrounds the outer periphery of the support member, and the frame is fixedly connected to the outer periphery of the support member; at least part of the support member forms the power feeding part, and at least part of the frame forms the radiator. While the frame serves as the frame and the appearance part of the mobile phone, it can also serve as the radiator, saving components, simplifying the assembly steps, increasing the assembly efficiency, and enhancing the radiation intensity of the antenna. The power feeding part is integrally formed on the support member, which can increase the structural strength of the support member, save components, simplify the assembly steps, and increase the assembly efficiency. In addition, a part of the frame serves as the radiator, so that at least part of the radiator becomes the appearance surface of the mobile phone, that is, at least part of the radiator is exposed on the outside and is in a visible state. Thus, it can not only avoid the radiator occupying the internal space of the mobile phone, but also avoid other components inside the electronic device from blocking the radiator, and further make the radiation intensity of the antenna stronger.

[0012] In some embodiments, the frame includes a first frame, at least a portion of which forms the radiator; the radiator is provided with a first perforation and a second perforation, and along the first direction, the first perforation and the second perforation both penetrate the radiator; the electronic device also includes a first keycap and a second keycap, the first keycap is installed in the first perforation, and the first keycap is fixedly connected to the first button; the second keycap is installed in the second perforation, and the second keycap is fixedly connected to the second button.

[0013] In the related art, as the number of frequency bands that mobile phones need to support increases, the number of corresponding antennas also increases, and the space required to set up the antennas also increases. However, the increase in the number of antennas runs counter to the trend of thinner and lighter mobile phones. In order to meet the number of antenna requirements, the parts of the mobile phone frame where other components are not set are also used as antenna radiators. Correspondingly, the empty positions on the support members are set with feeding parts connected to the antennas, but the number of antennas still cannot meet the demand.

[0014] In this embodiment, in order to solve the above problem, the area on the frame used to install the first keycap and the second keycap is also used. More specifically, the area on the first frame where the first keycap and the second keycap are installed is used to set the radiator. At the same time, the area on the support where the first key module and the second key module are installed is used to set the feeder, so that the radiator can be electrically connected to the RF chip on the device circuit board through the feeder, thereby realizing the function of the antenna. In this way, the number of antennas can be increased, and the antenna can be prevented from affecting the thin and light design of the mobile phone.

[0015] In some embodiments, the first keycap and the second keycap are both made of metal, so that the first keycap and the second keycap have a good operating feel. The outer surfaces of the first keycap and the second keycap are both provided with an insulating layer, so that the first keycap and the second keycap are insulated from each other, thereby preventing the first keycap and the second keycap from affecting the radiation performance of the radiator.

[0016] In some embodiments, the first through hole and the second through hole are connected to form a through hole; the first key cap and the second key cap are integrally formed, thereby facilitating processing and facilitating the simultaneous installation of the first key cap and the second key cap in the through hole, thereby increasing assembly efficiency and improving aesthetics.

[0017] In some embodiments, the radiator operates at medium and high frequencies. The length dimension of the through hole in the first direction is between 15 mm and 25 mm, and the width dimension of the through hole in the first direction is between 1.2 mm and 1.8 mm. If the length dimension or the width dimension of the through hole is too small, correspondingly, in order to enable the first keycap and the second keycap to be smoothly installed into the through hole, it is necessary to reduce the volume of the first keycap and the second keycap. However, if the volume of the first keycap and the second keycap is too small, it will be difficult for the user to operate. If the length dimension or the width dimension of the through hole is too large, it may result in a smaller volume of the radiator, thereby weakening the radiation performance of the radiator. By setting the length dimension of the through hole to be between 15 mm and 25 mm and the width dimension of the through hole to be between 1.2 mm and 1.8 mm, it is possible to make the through hole accommodate the first keycap and the second keycap that are convenient for the user to operate, and at the same time reduce the influence degree of the through hole on the radiation performance of the radiator.

[0018] In some embodiments, a storage portion and a receiving portion are provided inside the housing. Along the first direction, the frame, the storage portion, and the receiving portion are arranged in sequence; the storage portion includes a first storage portion and a second storage portion. Along the second direction, the first storage portion, the feeding portion, and the second storage portion are arranged in sequence; the first button is disposed in the first storage portion, the second button is disposed in the second storage portion, and the device circuit board is disposed in the receiving portion.

[0019] By arranging the storage portion and the receiving portion along the first direction, and arranging the first storage portion, the feeding portion, and the second storage portion along the second direction, and then disposing the first button in the first storage portion and the second button in the second storage portion, it is realized that the first button and the second button are spaced apart by the feeding portion along the second direction. Therefore, the first circuit board can connect the first button and the device circuit board at the shortest distance and can avoid the feeding portion, preventing interference between the first circuit board when connecting the first button and the device circuit board and the feeding portion. The second circuit board can connect the second button and the device circuit board at the shortest distance and can avoid the feeding portion, preventing interference between the second circuit board when connecting the second button and the device circuit board and the feeding portion.

[0020] In some embodiments, the support member further includes an engagement portion. Along the first direction, the frame, the engagement portion, and the feeding portion are connected in sequence; along the second direction, the surface of the first storage portion, the surface of the engagement portion, and the surface of the second storage portion are connected in sequence and are flush to form a sealing surface; the electronic device further includes a sealing member, and one side surface of the sealing member is connected to the sealing surface. The sealing member can be a foam. When the electronic device is assembled, the back plate is fixed to the frame to seal components such as the device circuit board inside the housing, preventing foreign matters such as dust from entering the inside of the housing.

[0021] In some embodiments, the first circuit board is a flexible circuit board, and the first circuit board includes a first connection portion, a first flexible portion, and a second connection portion that are sequentially connected; the first connection portion is disposed in the first accommodation portion, and the second connection portion is disposed in the accommodation portion; along the first direction, the first connection portion and the first button are stacked and connected; along the third direction, the second connection portion and the device circuit board are stacked and connected. The first connection portion is used to connect to the first button, the second connection portion is used to connect to the device circuit board, and the first flexible portion can be deformed so that the first circuit board can smoothly connect the first button and the device circuit board, and occupies a relatively small space.

[0022] In this embodiment, the first circuit board is a flexible circuit board. The first circuit board is used to connect the first button and the radio frequency chip of the device circuit board. The thickness of the first circuit board is relatively thin. On the one hand, it can reduce the volume of the first button module to save the internal space of the first housing. On the other hand, the first circuit board can be deformed, which can make the relative positions of the radio frequency chip and the first button more flexible. Specifically, the first button and the first connection portion are stacked along the first direction, and the second connection portion and the device circuit board are stacked along the third direction. That is, no matter how the relative positions of the radio frequency chip and the first button change, the electrical connection between the radio frequency chip and the first button can be realized through the deformation of the first circuit board. And the first circuit board can be deformed, which can also make the first circuit board fit the corresponding part of the first housing, thereby reducing the space occupied by the first circuit board, increasing the structural compactness after the first button module is assembled, and further saving the internal space of the first housing.

[0023] In some embodiments, the first accommodation portion is provided with a first accommodation groove, and both the first connection portion and the first button are disposed in the first accommodation groove; the electronic device further includes a first reinforcing plate, the first reinforcing plate is disposed in the first accommodation groove, the surface of the first reinforcing plate is stacked and connected to the surface of the first connection portion facing away from the first button, and the surface of the first reinforcing plate facing away from the first connection portion is fixed to the side surface of the first accommodation groove. The first reinforcing plate is connected to the first connection portion to support the first connection portion and enhance its structural strength, increasing the reliability of the connection between the first connection portion and the first button.

[0024] In some embodiments, a first positioning protrusion protrudes from one side of the notch of the first receiving groove of the first reinforcing plate, and a first positioning groove is recessed on the side wall surface of the first receiving groove; the first positioning protrusion is fixed in the first positioning groove to limit the displacement of the first reinforcing plate along the second direction. The first button is located inside the housing, and correspondingly, a first keycap is installed at the frame of the housing. The first keycap is used for the user to press, and the pressing force acts on the first button through the first keycap. The signal change generated by the first button is transmitted to the control chip through the first circuit board. After receiving the signal, the control chip controls the volume of the mobile phone to increase. The first positioning protrusion positions the first reinforcing plate in the second direction. The first button is fixed to the first reinforcing plate. Therefore, the first positioning protrusion also positions the position of the first button along the second direction, thereby avoiding the dislocation of the first button and the first keycap along the second direction, increasing the position accuracy of the first button and the first keycap along the second direction, and increasing the smoothness when pressing the first keycap.

[0025] In some embodiments, a second positioning protrusion protrudes from one side of the first reinforcing plate facing the bottom surface of the first receiving groove, a first positioning hole is provided on the bottom surface of the first receiving groove, and a second positioning groove is recessed on the wall surface of the first positioning hole; the second positioning protrusion extends into the first positioning hole and is fixed in the second positioning groove to limit the displacement of the first reinforcing plate along the third direction. Thus, the dislocation of the first button and the first keycap along the third direction can be avoided, the position accuracy of the first button and the first keycap along the third direction can be increased, and the smoothness when pressing the first keycap can be increased.

[0026] In some embodiments, a first gripping protrusion also protrudes from one side of the first reinforcing plate located at the notch of the first receiving groove, and the first gripping protrusion extends out of the first receiving groove. When assembling the first button, the first connecting portion of the first circuit board and the first reinforcing plate into the first receiving groove, the first gripping protrusion can be held by hand, and the first reinforcing plate can be installed in the first receiving groove from the notch of the first receiving groove. Since the first button and the first connecting portion are both fixedly connected to the first reinforcing plate, the first button and the first connecting portion are installed in the first receiving groove together with the first reinforcing plate. After assembly, at least part of the first gripping protrusion is located outside the first receiving groove. Then, the operator can break the first gripping protrusion from the first reinforcing plate, so that the first gripping protrusion is separated from the first reinforcing plate. Thus, during the installation process, the first gripping protrusion can be held by the operator. After the installation is completed, the first gripping protrusion is broken, which can prevent the first gripping protrusion from occupying space and prevent the first gripping protrusion from affecting the assembly of other components.

[0027] In some embodiments, the accommodating portion is provided with an accommodating cavity, a first accommodating groove is concavely provided on the bottom surface of the accommodating cavity, the device circuit board is disposed in the accommodating cavity, and the second connecting portion is disposed in the first accommodating groove. The second connecting portion is placed in the first accommodating groove, which makes full use of the space inside the housing and can prevent the second connecting portion from protruding and pressing against the device circuit board, which can increase the stability of the device circuit board and enable the second connecting portion to be smoothly connected to the device circuit board at the same time.

[0028] In some embodiments, the electronic device further includes a second reinforcing plate, the second reinforcing plate is disposed in the first accommodating groove, and the second reinforcing plate is laminated on the surface of the second connecting portion facing away from the device circuit board. The second reinforcing plate supports and reinforces the second connecting portion, which can facilitate the installation of the second connecting portion into the first installation groove and increase the stability of the connection between the second connecting portion and the device circuit board.

[0029] In some embodiments, the second circuit board is a flexible circuit board, and the second circuit board includes a third connecting portion, a second flexible portion, and a fourth connecting portion connected in sequence; the third connecting portion is disposed in the second accommodating portion, and the fourth connecting portion is disposed in the accommodating portion; along the first direction, the third connecting portion and the second button are laminated and connected; along the third direction, the fourth connecting portion and the device circuit board are laminated and connected. The third connecting portion is used to connect to the second button, the fourth connecting portion is used to connect to the device circuit board, and the second flexible portion can be deformed so that the second circuit board can smoothly connect the second button and the device circuit board and occupies a relatively small space.

[0030] The second circuit board is a flexible circuit board. The second circuit board is used to connect the radio frequency chip of the second button and the device circuit board. The thickness of the second circuit board is relatively thin, which can reduce the volume of the second button module to save the internal space of the first housing. The second circuit board can be deformed, which can make the relative positions of the radio frequency chip and the second button more flexible. Specifically, the third connecting portion and the second button are laminated along the first direction, and the fourth connecting portion and the device circuit board are laminated along the third direction. That is, no matter how the relative positions of the radio frequency chip and the second button change, the electrical connection between the radio frequency chip and the second button can be realized through the deformation of the second circuit board. And the second circuit board can be deformed, which can also make the second circuit board fit with the corresponding part of the first housing, thereby reducing the space occupied by the second circuit board, increasing the structural compactness after the assembly of the second button module, and further saving the internal space of the first housing.

[0031] In some embodiments, the second receiving portion is provided with a second receiving groove, and both the third connecting portion and the second button are disposed in the second receiving groove; the electronic device further includes a third reinforcing plate disposed in the second receiving groove, and a surface layer of the third reinforcing plate is connected to a surface of the third connecting portion facing away from the second button, and a surface of the third reinforcing plate facing away from the third connecting portion is fixed to a side surface of the second receiving groove. The third reinforcing plate is connected to the third connecting portion to support the third connecting portion and enhance its structural strength, thereby increasing the reliability of the connection between the third connecting portion and the second button.

[0032] In some embodiments, the third reinforcing plate protrudes with a third positioning protrusion on one side of the notch of the second receiving groove, and the side surface of the second receiving groove is recessed with a third positioning groove; the third positioning protrusion is fixed in the third positioning groove to limit the displacement of the third reinforcing plate along the second direction. The second button is located inside the housing, and correspondingly, a second key cap is installed at the border of the housing. The second key cap is used for the user to press, and the pressing force acts on the second button through the second key cap. The signal change generated by the second button is transmitted to the control chip through the second circuit board. After receiving the signal, the control chip controls the volume of the mobile phone to decrease. The second positioning protrusion positions the second reinforcing plate in the second direction. The second button is fixed to the third reinforcing plate. Therefore, the second positioning protrusion also positions the position of the second button along the second direction, thereby avoiding the dislocation of the second button and the second key cap along the second direction, increasing the positional accuracy of the second button and the second key cap along the second direction, and increasing the smoothness when pressing the second key cap.

[0033] In some embodiments, the third reinforcing plate protrudes with a fourth positioning protrusion on a side facing the bottom surface of the second receiving groove, the bottom surface of the second receiving groove is provided with a second positioning hole, and the hole wall surface of the second positioning hole is recessed with a fourth positioning groove; the fourth positioning protrusion extends into the second positioning hole and is fixed in the fourth positioning groove to limit the displacement of the third reinforcing plate along the third direction. Thereby, the dislocation of the second button and the second key cap along the third direction can be avoided, the positional accuracy of the second button and the second key cap along the third direction can be increased, and the smoothness when pressing the second key cap can be increased.

[0034] In some embodiments, a second gripping protrusion protrudes from one side of the notch of the second receiving groove of the third reinforcing plate, and the second gripping protrusion extends out of the second receiving groove. When assembling the second button, the third connecting portion of the second circuit board, and the third reinforcing plate into the second receiving groove, the second gripping protrusion can be held by hand, and the third reinforcing plate can be installed into the second receiving groove from the notch of the second receiving groove. Since both the second button and the third connecting portion are fixedly connected to the third reinforcing plate, the second button and the third connecting portion are installed into the second receiving groove together with the third reinforcing plate. After assembly, at least a part of the second gripping protrusion is located outside the second receiving groove. Then, the operator can break the second gripping protrusion from the third reinforcing plate, so that the second gripping protrusion is separated from the third reinforcing plate. Thus, during installation, the second gripping protrusion can be held by the operator. After installation, the second gripping protrusion is broken off, which can prevent the second gripping protrusion from occupying space and prevent the second gripping protrusion from affecting the assembly of other components.

[0035] In some embodiments, the accommodating portion is provided with an accommodating cavity, a second receiving groove is recessed on the bottom surface of the accommodating cavity, the device circuit board is disposed in the accommodating cavity, and the fourth connecting portion is disposed in the second receiving groove. Placing the fourth connecting portion in the second receiving groove makes full use of the space inside the housing and can prevent the fourth connecting portion from protruding and pressing against the device circuit board, which can increase the stability of the device circuit board and enable the fourth connecting portion to be smoothly connected to the device circuit board.

[0036] In some embodiments, the electronic device further includes a fourth reinforcing plate, the fourth reinforcing plate is disposed in the second receiving groove, and the fourth reinforcing plate is laminated on the surface of the fourth connecting portion facing away from the device circuit board.

[0058] The embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0059] The embodiments of the present application provide an electronic device, which includes but is not limited to a straight cell phone, a foldable cell phone, a notebook computer, a tablet personal computer, a personal digital assistant, a wearable device or a vehicle-mounted device, etc. The wearable device may specifically be a wearable watch, a wearable bracelet, etc.

[0060] In the embodiments of the present application, a foldable cell phone is taken as an example for illustration.

[0061] Please refer to Figure 1 and Figure 2 , Figure 1 which is the schematic diagram of the first state of the cell phone 1000 provided by the embodiments of the present application, Figure 2 which is the schematic diagram of the second state of the cell phone 1000 provided by the embodiments of the present application.

[0062] Figure 1 The foldable cell phone 1000 shown is in a folded state, Figure 2 The foldable cell phone 1000 shown is in an unfolded state. Figure 2 The unfolding angle of the foldable cell phone 1000 shown is 180 degrees. It should be noted that there may be a slight deviation in the angles illustrated in the embodiments of the present application. For example, Figure 2 the unfolding angle of the foldable cell phone 1000 shown being 180 degrees means that it can be 180 degrees or 180 ± 10 degrees. The same understanding can be made for the angles illustrated hereinafter.

[0063] For ease of description, the length direction of the foldable mobile phone 1000 is defined as the X-axis direction (the first direction), the width direction of the foldable mobile phone 1000 is defined as the Y-axis direction (the second direction), and the thickness direction of the foldable mobile phone 1000 is defined as the Z-axis direction (the third direction). The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other pairwise. In other embodiments, the first direction may be the Y-axis direction, and the second direction may be the X-axis direction.

[0064] It should be noted that the orientation terms such as "top", "bottom", "left", "right", "front", and "back" used in the embodiments of this application to describe the mobile phone 1000 are mainly based on the display orientation of the mobile phone 1000 in the appendix Figure 2 for elaboration. Taking the positive direction of the Z-axis as "top" and "up", the negative direction of the Z-axis as "bottom" and "down", the positive direction of the X-axis as "right", the negative direction of the X-axis as "left", the positive direction of the Y-axis as "back", and the negative direction of the Y-axis as "front", which does not form a limitation on the orientation of the mobile phone 1000 in the actual application scenario.

[0065] The foldable mobile phone 1000 includes a main body 1100 and a display screen 1200, and the display screen 1200 is installed on the main body 1100. The display screen 1200 includes a display surface and an installation surface, and the display surface and the installation surface are arranged opposite to each other. The display surface is used to display text, images, videos, etc. The display screen 1200 includes a first display part 1210, a second display part 1220, and a third display part 1230. The third display part 1230 is located between the first display part 1210 and the second display part 1220, and the third display part 1230 is flexible and can be bent along the X direction. The first display part 1210 and the second display part 1220 can actually be bent when not fixed. The direction of the display screen 1200 for displaying the picture can be parallel to the X-axis direction or parallel to the Y-axis direction.

[0066] In this embodiment, the display screen 1200 is a flexible display screen 1200. For example, it can be an organic light-emitting diode (OLED) display screen 1200, an active-matrix organic light-emitting diode (AMOLED) display screen 1200, a mini organic light-emitting diode display screen 1200, a micro organic light-emitting diode display screen 1200, a microorganic light-emitting diode display screen 1200, or a quantum dot light emitting diodes (QLED) display screen 1200.

[0067] Please refer to Figure 1 and Figure 2 , the main body 1100 includes a housing and a rotating mechanism 700. The housing includes a first housing 500 and a second housing 600. The rotating mechanism 700 is connected between the first housing 500 and the second housing 600. When the rotating mechanism 700 rotates, the first housing 500 and the second housing 600 are relatively unfolded or relatively folded.

[0068] In this embodiment, the rotating mechanism 700 can be a hinge. The rotating mechanism 700 is connected between the first housing 500 and the second housing 600, which is equivalent to the rotating structure between the first housing 500 and the second housing 600 to achieve the relative free rotation and relative folding of the first housing 500 and the second housing 600. Specifically, the rotating mechanism 700 includes two connected hinges arranged in sequence along the Y-axis direction. One hinge is connected to the first housing 500, and the other hinge is connected to the second housing 600; alternatively, the rotating mechanism 700 includes one hinge that extends from one side of the mobile phone 1000 to the other side in the Y-axis direction. In other embodiments, the rotating mechanism 700 is two connected and relatively rotatable rotating shafts. One rotating shaft is rotatably connected to the first housing 500, and the other rotating shaft is rotatably connected to the second housing 600 to achieve the relative rotation of the first housing 500 and the second housing 600. In other embodiments, the rotating mechanism 700 can also be a rotating structure with other structures, as long as it can achieve the relative free rotation and relative folding of the first housing 500 and the second housing 600 without damaging the display screen 1200.

The thickness dimensions of the first receiving portion 570, the second receiving portion 580, and the connecting portion 590 are substantially the same to facilitate the first receiving portion 570 to support the seal.

[0083] Figure 6 Yes Figure 2 It is a schematic diagram of a partial structure of the mobile phone 1000 shown in. In this embodiment, the antenna 300 includes a feeding portion 310, a radiator 320, and a spring piece (not shown in the figure). The feeding portion 310 can be a part of the support member 540, that is, a part of the support member 540 constitutes the feeding portion 310. Or rather, the feeding portion 310 is integrally formed on the first housing 500. More specifically, the feeding portion 310 can be integrally formed on the support member 540. Thus, there is no need to additionally provide other devices as the feeding portion 310, reducing the number of components of the mobile phone 1000, avoiding the steps of assembling the feeding portion 310, simplifying the assembling steps, and increasing the assembling efficiency. Specifically, the feeding portion 310 can be the part of the support member 540 located between the first receiving portion 570 and the second receiving portion 580, and the feeding portion 310 sinks relative to the first receiving portion 570 and the second receiving portion 580. The thicknesses of the first receiving portion 570 and the second receiving portion 580 are both greater than the thickness of the feeding portion 310. Specifically, in other words, the first receiving portion 570, the feeding portion 310, and the second receiving portion 580 are arranged in sequence along the Y-axis direction, and the feeding portion 310 is located in the U-shaped space surrounded by the first receiving portion 570, the connecting portion 590, and the second receiving portion 580.

[0084] In this embodiment, the surface of the feeding portion 310 facing away from the first surface 541 is basically flush with the surface of the device circuit board 400 to facilitate the connection between the feeding portion 310 and the device circuit board 400. Here, the same includes processing errors.

[0085] The radiator 320 can be part of the frame 530, that is, a part of the frame 530 constitutes the radiator 320. Or rather, the radiator 320 is integrally formed on the first housing 500. More specifically, the radiator 320 can be integrally formed on the frame 530. Using a part of the frame 530 as the radiator 320 eliminates the need to additionally set up other devices as the radiator 320, reducing the number of components of the mobile phone 1000, avoiding the steps of assembling the radiator 320, simplifying the assembly steps, and increasing the assembly efficiency. It can be understood that at least part of the connection part 590 can be made of conductive metal, and at least part of the connection part 590 is used as the radiator 320 so that the feeding part 310 can be connected to the radiator 320. It can be understood that the parts of the first middle frame 510 used as the feeding part 310 and the radiator 320 are all made of conductive metal. The remaining part of the first middle frame 510 can be made of insulating materials such as plastic or made of metal.

[0086] The radiator 320 can be constituted by a part of the frame 530. Specifically, the radiator 320 can be constituted by a part of the first frame 531. The part of the first frame 531 serving as the radiator 320 is made of conductive metal, and the other part of the first frame 531 is an insulating part 534( Figure 6 as shown in the figure). The insulating part 534 is located between the support 540 and the radiator 320. The length of the radiator 320 in the Y-axis direction can be designed according to the frequency bands that the antenna 300 needs to support. In one embodiment, the radiator 320 needs to radiate signals in the medium and high frequency bands, and the range of the medium and high frequency bands is 1000 MHz to 3000 MHz. Then the length of the radiator is about 1 / 4 wavelength of the signal radiated by the radiator. This embodiment is not limited. The thickness dimension of the first frame 531 in the Z-axis direction is substantially the same as the thickness dimension of the appearance of the mobile phone 1000. Using a part of the first frame 531 as the radiator 320, the thickness dimension of the radiator 320 can be substantially the same as the thickness dimension of the appearance of the mobile phone 1000. Thus, when the frequency bands supported by the antenna 300 are the same, the length of the radiator 320 is basically fixed. However, if the thickness dimension of the radiator 320 is relatively thick, the volume of the radiator 320 is large, and the large volume of the radiator 320 can make the radiation ability of the antenna 300 stronger.

[0087] In addition, the radiator 320 can be constituted by the frame 530. As an appearance component of the mobile phone 1000, at least part of the radiator 320 forms the appearance part of the mobile phone 1000. That is, the radiator 320 can form a part of the appearance surface of the mobile phone 1000. At this time, at least part of the radiator 320 is in a visible state. Thus, it can not only avoid the radiator 320 occupying the internal space of the mobile phone 1000, but also avoid other components inside the mobile phone 1000 from blocking the radiator 320, thereby making the radiation intensity of the antenna 300 stronger.

[0088] In this embodiment, the radiator 320 is provided with a first through hole 321 and a second through hole 322. Along the X-axis direction, the first through hole 321 and the second through hole 322 both penetrate the radiator 320. The first through hole 321 is connected to the first receiving groove 571, and the second through hole 322 is connected to the second receiving groove 581. The first key module 100 includes a first key cap 130, and the second key module 200 includes a second key cap 230. The first through hole 321 is used to install the first key cap 130, and a portion of the first key cap 130 extends into the first receiving groove 571, so that the first key cap 130 can be connected to other components located in the first receiving groove 571. The second through hole 322 is used to install the second key cap 230. The first keycap 130 and the second keycap 230 can both be made of metal, so that the first keycap 130 and the second keycap 230 have a good operating feel. The outer surfaces of the first keycap 130 and the second keycap 230 are both provided with an insulating layer (not shown), so that the first keycap 130 and the second keycap 230 are insulated from each other, thereby preventing the first keycap 130 and the second keycap 230 from affecting the radiation performance of the radiator 320. In other embodiments, the first keycap 130 and the second keycap 230 can also be made of plastic.

[0089] In this embodiment, the first keycap 130 and the second keycap 230 are integrally formed, and the first through-hole 321 and the second through-hole 322 are connected along the Y-axis direction to form a through-hole 323. As a result, it is easy to process and the first keycap 130 and the second keycap 230 are installed in the through-hole 323 at the same time to increase the assembly efficiency and improve the aesthetics. Of course, in other embodiments, the first keycap 130 and the second keycap 230 can also be formed separately, that is, the first keycap 130 and the second keycap 230 are two independent parts, and the first through-hole 321 and the second through-hole 322 can also be two independent holes.

[0090] In this embodiment, the length dimension of the through hole 323 in the Y-axis direction is between 15 mm and 25 mm. Specifically, the length dimension of the through hole 323 can be 15 mm, 18 mm, 21 mm, 24 mm, 25 mm, etc. The width dimension of the through hole 323 in the Z-axis direction is between 1.2 mm and 1.8 mm. Specifically, the width dimension of the through hole 323 can be 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, etc. If the length dimension or the width dimension of the through hole 323 is too small, correspondingly, in order to enable the first keycap 130 and the second keycap 230 to be smoothly installed into the through hole 323, it is necessary to reduce the volume of the first keycap 130 and the second keycap 230. However, if the volume of the first keycap 130 and the second keycap 230 is too small, it will be difficult for users to operate. If the length dimension or the width dimension of the through hole 323 is too large, it may cause the volume of the radiator 320 to be small, thereby weakening the radiation performance of the radiator 320. By setting the length dimension of the through hole 323 between 15 mm and 25 mm and the width dimension of the through hole 323 between 1.2 mm and 1.8 mm, the through hole 323 can accommodate the first keycap 130 and the second keycap 230 that are convenient for users to operate, and at the same time, the influence of the through hole 323 on the radiation performance of the radiator can be reduced.

[0091] In the related art, as the number of frequency bands that the mobile phone 1000 needs to support increases, the number of corresponding antennas 300 also increases, and the space required to set up the antennas 300 is also getting larger. However, the increase in the number of antennas 300 runs counter to the trend of the mobile phone 1000 being thinner and lighter. To meet the demand for the number of antennas 300, the parts of the frame 530 of the mobile phone 1000 where no other components are provided are also used as the radiator 320 of the antenna 300. Correspondingly, the feeding part 310 connected to the antenna 300 is arranged at the vacant position on the support 540. However, the number of antennas 300 still cannot meet the demand.

[0092] In this embodiment, to solve the above problems, the area on the frame 530 for installing the first keycap 130 and the second keycap 230 is also utilized. More specifically, the area of the first frame 531 for setting the first keycap 130 and the second keycap 230 is used to set the radiator 320. At the same time, the area of the support 540 for installing the first key module 100 and the second key module 200 is used to set the feeding part 310, so that the radiator 320 can be electrically connected to the RF chip of the device circuit board 400 through the feeding part 310, thereby realizing the function of the antenna 300. Thus, both the number of antennas 300 can be increased, and the influence of the antennas 300 on the thin and light design of the mobile phone 1000 can be prevented.

[0093] In this embodiment, one end of the elastic sheet is connected to the RF chip, and the other end of the elastic sheet is connected to the feeding part 310. The feeding part 310 is further connected to the radiator 320. As a result, the signal emitted by the RF chip can be transmitted to the radiator 320 through the elastic sheet and the feeding part 310 in sequence, and then the radiator 320 radiates the signal. After receiving the signal transmitted by the elastic sheet, the feeding part 310 can also directly radiate the signal. The signal received by the radiator 320 can also be transmitted to the RF chip through the feeding part 310 and the elastic sheet in sequence. In addition to receiving the signal transmitted by the radiator 320, the feeding part 310 can also directly receive external signals, and the signal directly received by the feeding part 310 can also be transmitted to the RF chip through the elastic sheet to realize the communication function of the mobile phone 1000.

[0094] Please refer to Figure 7 and Figure 8 , Figure 7 is Figure 2 a partial structural schematic diagram of the first button module 100 of the mobile phone 1000 shown in Figure 8 is Figure 7 a split structural schematic diagram of the first button module 100 shown in

[0095] In this embodiment, the first button module 100 includes a first button 110, a first circuit board 120, a first keycap 130 ( Figure 3 shown in

[0096] ), a first reinforcing plate 140, and a second reinforcing plate 160. The first circuit board 120 can be a flexible circuit board. In other embodiments, the first circuit board 120 can also be a rigid circuit board or a conductive component and other devices.

[0097] Please refer to Figure 9 , Figure 9 isFigure 8 Schematic diagram of the structure of the first circuit board 120 of the first button module 100 shown in

[0098] In this embodiment, the first circuit board 120 includes a first connection portion 121, a first flexible portion 122, and a second connection portion 123 that are sequentially connected in the X-axis direction. The first connection portion 121 is used to connect to the first button 110. The first flexible portion 122 connects the first connection portion 121 and the second connection portion 123. The second connection portion 123 is used to connect to the device circuit board 400. Moreover, the width of the first flexible portion 122 is smaller than the width of the first connection portion 121, and the width of the first flexible portion 122 is smaller than the width of the second connection portion 123. Thus, the first connection portion 121 can be reliably connected to the first button 110, the second connection portion 123 can be reliably connected to the device circuit board 400, and the first flexible portion 122 can not only reliably connect the first connection portion 121 and the second connection portion 123, but also has a small area, which can reduce the space occupied by the first circuit board 120 and reduce material consumption.

[0099] Please refer to Figure 10 , Figure 10 is Figure 8 Schematic diagram of the structure of the first reinforcement plate 140 of the first button module 100 shown in

[0100] In this embodiment, the first reinforcement plate 140 includes a first long side 141 and a second long side 142. The first long side 141 is convexly provided with a first positioning protrusion 143 and a first gripping protrusion 144. The first positioning protrusion 143 includes a first extension portion 145 and a first positioning portion 146. One end of the first extension portion 145 is fixedly connected to the first long side 141, and the first positioning portion 146 is fixedly connected to the other end of the first extension portion 145, and the first positioning portion 146 and the first extension portion 145 are perpendicular to each other. In other words, the first extension portion 145 and the first positioning portion 146 are connected in an L shape, and the end of the first extension portion 145 away from the first positioning portion 146 is fixedly connected to the first long side 141. The first positioning portion 146 is used to cooperate with the first receiving portion 570 to limit the displacement of the first reinforcement plate 140 in the Y-axis direction.

[0101] In other embodiments, the first extension portion 145 and the first positioning portion 146 may not be perpendicular. For example, the included angle between the first extension portion 145 and the first positioning portion 146 may be 70 degrees or 80 degrees, etc.

[0102] In this embodiment, the first gripping protrusion 144 is used to facilitate the assembly of the first button module 100 to the first receiving portion 570. The first gripping protrusion 144 includes a first gripping portion 147, a first connecting leg 148, and a second connecting leg 149. The first gripping portion 147 can be in the shape of a rectangular sheet. The first connecting leg 148 and the second connecting leg 149 are both connected to the long side of the first gripping portion 147, and the first connecting leg 148 and the second connecting leg 149 are spaced apart. One end of the first connecting leg 148 away from the first gripping portion 147 is fixedly connected to the first long side 141, and one end of the second connecting leg 149 away from the first gripping portion 147 is fixedly connected to the first long side 141. The first positioning protrusion 143 is located between the first connecting leg 148 and the second connecting leg 149. Thus, on the premise that the length of the first long side 141 is limited, the space of the first long side 141 is fully utilized to arrange the first gripping protrusion 144 and the first positioning protrusion 143, so that the positioning and convenient assembly of the first button module 100 in the Y-axis direction can be realized. In other embodiments, the first gripping protrusion 144 can also be of other shapes, such as semi-circular, etc., without limitation as long as it is convenient to grip and avoids the first positioning protrusion 143.

[0103] It can be understood that Figure 10 the position of the first positioning protrusion 143 shown between the first connecting leg 148 and the second connecting leg 149 is only exemplary. In fact, the first positioning protrusion 143 can also be connected to other positions of the first long side 141.

[0104] A second positioning protrusion 150 protrudes from the second long side 142. The second positioning protrusion 150 includes a second extension portion 151 and a second positioning portion 152. One end of the second extension portion 151 is fixedly connected to the second long side 142, and the second positioning portion 152 is fixedly connected to the other end of the second extension portion 151, and the second positioning portion 152 and the second extension portion 151 are perpendicular to each other. In other words, the second extension portion 151 and the second positioning portion 152 are connected in an L shape, and one end of the second extension portion 151 away from the second positioning portion 152 is fixedly connected to the second long side 142. The second positioning portion 152 is used to cooperate with the first receiving portion 570 to limit the displacement of the second reinforcing plate 160 in the Z-axis direction. In this embodiment, the number of the second positioning protrusions 150 is one. In other embodiments, the number of the second positioning protrusions 150 can also be two or three, etc. The second extension portion 151 and the second positioning portion 152 may not be perpendicular either. For example, the included angle between the second extension portion 151 and the second positioning portion 152 can be 73 degrees or 87 degrees, etc. It can be understood that Figure 10 the position of the second positioning protrusion 150 shown connected to the second long side 142 is only exemplary. In fact, the second positioning protrusion 150 can also be connected to other positions of the second long side 142.

[0105] In this embodiment, the first button 110, the first connection part 121 of the first circuit board 120, and the first reinforcing plate 140 are stacked in sequence. The first button 110 and the first connection part 121 are fixedly connected to achieve the electrical connection between the first button 110 and the first connection part 121, and the first connection part 121 and the first reinforcing plate 140 are fixedly bonded by an adhesive. The second connection part 123 of the first circuit board 120 and the second reinforcing plate 160 are stacked, and the second connection part 123 and the second reinforcing plate 160 are fixedly bonded by an adhesive. The first reinforcing plate 140 supports and strengthens the first connection part 121 and the first button 110. At this time, the first connection part 121 will not be deformed. The second reinforcing plate 160 supports and strengthens the second connection part 123. At this time, the second connection part 123 will not be deformed. The first flexible part 122 can be deformed so that the first connection part 121 and the second connection part 123 can be in a perpendicular state, facilitating the assembly of the first button module 100 to the first housing 500. The first flexible part 122 of the first circuit board 120 is located between the second connection pin 149 and the first positioning projection 143. In other words, the first connection pin 148, the first flexible part 122, the first positioning projection 143, and the second connection pin 149 are arranged in sequence. Thus, within the limited space of the first long side 141, the first connection pin 148, the first flexible part 122, the first positioning projection 143, and the second connection pin 149 do not interfere with each other, increasing the structural stability of the first button module 100. The first positioning projection 143 and the second positioning projection 150 are located on opposite sides of the first reinforcing plate 140, making full use of the space on the first reinforcing plate 140.

[0106] Please refer to Figure 11 and Figure 12 , Figure 11 is Figure 2 a partial structural schematic diagram of the second button module 200 of the mobile phone 1000 shown in Figure 12 is Figure 11 a split structural schematic diagram of the second button module 200 shown in

[0107] The second button module 200 includes a second button 210, a second circuit board 220, a second keycap 230 ( Figure 3 shown in

[0108] Please refer to Figure 13 , Figure 13 which Figure 12 is a schematic structural diagram of the second circuit board 220 of the second button module 200 shown in

[0109] In this embodiment, the second circuit board 220 includes a third connection portion 221, a second flexible portion 222, and a fourth connection portion 223 that are sequentially connected along the X-axis direction. The third connection portion 221 is used to connect to the second button 210, the second flexible portion 222 is used to connect the third connection portion 221 and the fourth connection portion 223, and the fourth connection portion 223 is used to connect to the device circuit board 400. The width of the second flexible portion 222 is smaller than the width of the third connection portion 221, and the width of the second flexible portion 222 is smaller than the width of the fourth connection portion 223. The second flexible portion 222 is provided in an L shape so that the second button 210 can be electrically connected through the second circuit board 220. Specifically, the second flexible portion 222 includes a first flexible segment 224 and a second flexible segment 225. The first flexible segment 224 and the second flexible segment 225 are connected in an L shape. The first flexible segment 224 extends along the X-axis direction, and one end of the first flexible segment 224 away from the second flexible segment 225 is connected to the third connection portion 221. The second flexible segment 225 extends along the Y-axis direction, and one end of the second flexible segment 225 away from the first flexible segment 224 is connected to the fourth connection portion 223. Thus, the third connection portion 221 can be reliably connected to the second button 210, the fourth connection portion 223 can be reliably connected to the device circuit board 400, and the second flexible portion 222 can not only reliably connect the third connection portion 221 and the fourth connection portion 223, but also has a small area, which can reduce the space occupied by the second circuit board 220 and reduce material consumption. In other embodiments, the third connection portion 221, the second flexible portion 222, and the fourth connection portion 223 can also be of other shapes.

[0110] Please refer to Figure 14 , Figure 14 which Figure 12 is a schematic structural diagram of the third reinforcing plate 240 shown in

[0111] The third reinforcing plate 240 includes a third long side 241 and a fourth long side 242. The third long side 241 is convexly provided with a third positioning protrusion 243 and a second holding protrusion 244. The second holding protrusion 244 includes a second holding portion 247, a third connecting leg 248, and a fourth connecting leg 249. The third positioning protrusion 243 includes a third extending portion 245 and a third positioning portion 246. The fourth long side 242 is convexly provided with a fourth positioning protrusion 250. The fourth positioning protrusion 250 includes a fourth extending portion 251 and a fourth positioning portion 252. The structure, connection relationship, and function of each component in the third reinforcing plate 240 can refer to the relevant description of the first reinforcing plate.

[0112] Please refer to Figure 15 , Figure 15 which Figure 2 is a schematic diagram of the partial structural assembly state of the mobile phone 1000 shown in Figure 15 . The first gripping protrusion 144 of the first reinforcing plate 140 shown in

[0113] is not broken, and the second gripping protrusion 244 of the third reinforcing plate 240 is not broken. When assembling the mobile phone 1000, the operator holds the first gripping protrusion 144 and installs the first reinforcing plate 140 into the first receiving groove 571 from the notch of the first receiving groove 571. Since both the first button 110 and the first connecting portion 121 are fixedly connected to the first reinforcing plate 140, the first button 110 and the first connecting portion 121 are installed into the first receiving groove 571 together with the first reinforcing plate 140. During installation, the side of the first button 110 facing away from the first connecting portion 121 abuts against the first keycap 130, and the side of the first reinforcing plate 140 facing away from the first connecting portion 121 is adhered to the side surface of the first receiving groove 571 by an adhesive. In other words, the first keycap 130, the first button 110, the first connecting portion 121, and the first reinforcing plate 140 are sequentially stacked and fixed along the X-axis direction.

[0114] The first long side 141 of the first reinforcing plate 140 is located at the notch of the first receiving groove 571. The first positioning portion 146 of the first positioning protrusion 143 extends into the first positioning groove 572, and the first positioning portion 146 abuts against the bottom surface of the first positioning groove 572 to limit the movement of the first reinforcing plate 140 along the Y-axis direction, that is, to limit the movement of the first button 110 and the first connecting portion 121 along the Y-axis direction. Furthermore, it is possible to avoid misalignment of the first button 110 and the first keycap 130 along the Y-axis direction, increase the positional accuracy of the first button 110 and the first keycap 130 along the Y-axis direction, and increase the smoothness when pressing the first keycap 130.

[0115] Please refer to Figure 16 , Figure 16 which Figure 15 is a schematic diagram of another perspective of the partial structure of the mobile phone 1000 shown in

[0116] . The second extension portion 151 of the second positioning protrusion 150 extends into the first positioning hole 573, and the second positioning portion 152 of the second positioning protrusion 150 extends into the second positioning groove 574. The second positioning portion 152 abuts against the bottom surface of the second positioning groove 574 to limit the movement of the first reinforcing plate 140 along the Z-axis direction, that is, to limit the movement of the first button 110 and the first connecting portion 121 along the Z-axis direction. Furthermore, it is possible to avoid misalignment of the first button 110 and the first keycap 130 along the Z-axis direction, increase the positional accuracy of the first button 110 and the first keycap 130 along the Z-axis direction, and increase the smoothness when pressing the first keycap 130.

[0117] The first gripping protrusion 144 is at least partially located outside the first receiving groove 571. Then, the operator can break the first gripping protrusion 144 from the first reinforcing plate 140, so that the first gripping protrusion 144 is separated from the first reinforcing plate 140.

[0118] Please refer to Figure 17 and Figure 18 , Figure 17 is Figure 2 a schematic diagram of the assembled state of a partial structure of the mobile phone 1000 shown in Figure 18 is Figure 17 an enlarged schematic diagram of the structure at position A in Figure 17 and Figure 18 the first gripping protrusion 144 of the first reinforcing plate 140 shown in has been broken off. Thus, during the installation process, the first gripping protrusion 144 can be held by the operator. After the installation is completed, the first gripping protrusion 144 is broken off, which can prevent the first gripping protrusion 144 from occupying space and prevent the first gripping protrusion 144 from affecting the assembly of other components.

[0119] Next, the operator can hold the second reinforcing plate 160 and the second connecting portion 123 and install the second reinforcing plate 160 and the second connecting portion 123 in the first receiving groove 561, so that the second connecting portion 123 is perpendicular to the first connecting portion 121. The second connecting portion 123 and the second reinforcing plate 160 are stacked and fixed along the Z-axis direction. Then, the surface of the second reinforcing plate 160 facing away from the second connecting portion 123 can be bonded to the bottom surface of the first receiving groove 561 by an adhesive. The second reinforcing plate 160 and the second connecting portion 123 are placed in the first receiving groove 561, making full use of the space inside the housing, and can prevent the second reinforcing plate 160 and the second connecting portion 123 from protruding and pressing against the device circuit board 400, which can increase the stability of the device circuit board 400 and at the same time enable the second connecting portion 123 to be smoothly connected to the device circuit board 400.

[0120] The perpendicularity between the second connecting portion 123 and the first connecting portion 121 can be achieved by the deformation of the first flexible portion 122. Specifically, the first part of the first flexible portion 122 is bent 90 degrees relative to the first connecting portion 121 and is located in the first avoiding groove 575. The second part of the first flexible portion 122 is bent 90 degrees relative to its first part and is stacked on the side of the first receiving portion 570 away from the first frame 531, and the second part of the first flexible portion 122 is parallel to the first connecting portion 121. At this time, the second connecting portion 123 is perpendicular to the first connecting portion 121.

[0121] Please refer to Figure 17 and Figure 19 , Figure 19 is Figure 17Schematic diagram of the enlarged structure at position B. Figure 17 and Figure 19 The state where the second button module 200 is installed is shown in Figure 19 . The process of installing the second button module 200 can refer to the process of installing the first button module 100, which will not be elaborated in this embodiment.

[0122] After both the first button module 100 and the second button module 200 are installed, the device circuit board 400 can be installed into the accommodating cavity, and the second connection portion 123 and the control chip are connected through a board-to-board connector, and the fourth connection portion 223 and the control chip are connected through a board-to-board connector. A shrapnel is used to connect the power feeding portion 310 and the radio frequency chip.

[0123] After the first button module 100 and the second button module 200 are installed, along the Y-axis direction (the second direction), there is a gap between the first circuit board 120 and the power feeding portion 310, and there is a gap between the second circuit board 220 and the power feeding portion 310. Further, it can avoid the first circuit board 120 from affecting the signal radiation intensity of the power feeding portion 310, and avoid the second circuit board 220 from affecting the signal radiation intensity of the power feeding portion 310. Along the X-axis direction, there is a gap between the first circuit board 120 and the radiator 320, and there is also a gap between the second circuit board 220 and the radiator 320. Further, it can avoid the first circuit board 120 from affecting the signal radiation intensity of the radiator 320, and avoid the second circuit board 220 from affecting the signal radiation intensity of the radiator 320. The first circuit board 120 and the radiator 320 can be separated by an insulating portion 534 and a first receiving portion 570, and the second circuit board 220 and the radiator 320 can also be separated by an insulating portion 534 and a second receiving portion 580.

[0124] Further, along the Y-axis direction, the gap between the first circuit board 120 and the power feeding portion 310 is at least 0.8 mm. The gap between the first circuit board 120 and the power feeding portion 310 can specifically be 0.8 mm, 1 mm, or 1.2 mm, etc. The gap between the second circuit board 220 and the power feeding portion 310 is at least 0.8 mm. The gap between the second circuit board 220 and the power feeding portion 310 can specifically be 0.8 mm, 0.9 mm, or 1.1 mm, etc. Thus, there is enough clearance area between the first circuit board 120 and the power feeding portion 310, and there is also enough clearance area between the second circuit board 220 and the power feeding portion 310, so that the radiation performance of the power feeding portion 310 can be better exerted.

[0125] There is a gap of at least 0.8 mm between the first circuit board 120 and the radiator 320. Specifically, it can be 0.8 mm, 1 mm, 1.3 mm, 1.5 mm, etc. There is a gap of at least 0.8 mm between the second circuit board 220 and the radiator 320. Specifically, it can be 0.8 mm, 0.9 mm, 1.1 mm, 1.3 mm, etc. Thus, there is sufficient clearance area between the first circuit board 120 and the radiator 320, and there is also sufficient clearance area between the second circuit board 220 and the radiator 320, enabling the radiation performance of the radiator 320 to be better exerted.

[0126] In addition, in this embodiment, the first circuit board 120 is used to connect the first button 110 and the RF chip of the device circuit board 400. The thickness dimension of the first circuit board 120 is between 0.08 mm and 0.15 mm. The thickness of the first circuit board 120 is relatively thin. On the one hand, it can reduce the volume of the first button module 100 to save the internal space of the first housing 500. On the other hand, the first flexible part 122 can deform, enabling the relative positions of the RF chip and the first button 110 to be relatively flexible. That is, no matter how the relative positions of the RF chip and the first button 110 change, the electrical connection between the RF chip and the first button 110 can be achieved through the deformation of the first flexible part 122. And since the first flexible part 122 can deform, it can also make the first flexible part 122 fit with the corresponding part of the first housing 500, thereby reducing the space occupied by the first flexible part 122, increasing the structural compactness of the first button module 100 after assembly, and further saving the internal space of the first housing 500.

[0127] Similarly, the second circuit board 220 is used to connect the second button 210 and the RF chip of the device circuit board 400. The thickness dimension of the second circuit board 220 is between 0.08 mm and 1.5 mm. The thickness of the second circuit board 220 is relatively thin, which can reduce the volume of the second button module 200 to save the internal space of the first housing 500. The second flexible part 222 can deform, enabling the relative positions of the RF chip and the second button 210 to be relatively flexible. That is, no matter how the relative positions of the RF chip and the second button 210 change, the electrical connection between the RF chip and the second button 210 can be achieved through the deformation of the second flexible part 222. And since the second flexible part 222 can deform, it can also make the second flexible part 222 fit with the corresponding part of the first housing 500, thereby reducing the space occupied by the second flexible part 222, increasing the structural compactness of the second button module 200 after assembly, and further saving the internal space of the first housing 500.

[0128] Please refer to Figure 20 , Figure 20 is Figure 2Schematic diagram of the partial internal structure of the first housing shown in the figure.

[0129] The device circuit board 400 and the battery 800 are arranged along the Y-axis direction, and the battery 800 is used to supply power to devices such as the device circuit board 400. The first button 110 is located on the left side of the device circuit board 400. Therefore, by arranging the first flexible part 122 to extend along the X-axis direction, the first button 110 can be electrically connected to the device circuit board 400 through the first circuit board 120. The second button 210 is located on the left side of the battery 800. Therefore, the second flexible part 222 is arranged in an L shape. Specifically, the second flexible part 222 includes a first flexible section 224 and a second flexible section 225, and the first flexible section 224 and the second flexible section 225 are connected in an L shape. The first flexible section 224 extends along the X-axis direction, and the second flexible section 225 extends along the Y-axis direction, so that the second circuit board 220 can avoid the battery 800 and be connected to the device circuit board 400, enabling the second button 210 to be electrically connected to the device circuit board 400 through the second circuit board 220.

[0130] The above are only partial embodiments and implementation manners of the present application. The protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present application, and all should be covered by the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
