[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 25, 2023, with application number 202311591999.7 and application name “Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electronic products, and in particular to an electronic device. Background Art

[0003] As the frequency bands supported by electronic devices and the demand for transmitting or receiving signals increase, the radiation intensity requirements for antennas are getting higher and higher. However, the antenna assembly in current electronic devices is relatively troublesome and the radiation intensity is relatively weak.

[0004] Summary of the Invention

[0005] The present application provides an electronic device with an antenna that does not require assembly and has a strong radiation intensity.

[0006] The present application provides an electronic device, comprising: 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 comprises a radiator and a feeder, and the radiator and the feeder are both integrally formed in the housing; the first button, the second button, the first circuit board, the second circuit board, the feeder, and the device circuit board are all arranged inside the housing.

[0007] The electronic device may be a foldable mobile phone, comprising a first housing and a second housing, the first housing and the second housing being rotatably connected, the housing being either the first housing or the second housing. The electronic device may also be a bar phone.

[0008] The first button may be a volume increase button, and the second button may be a volume decrease button. The device circuit board may integrate a radio frequency chip and a control chip. The radio frequency chip is electrically connected to the power feeder. The signal transmitted by the radio frequency chip may be transmitted to the power feeder, which in turn transmits the signal to the radiator. The radiator transmits the signal, allowing the electronic device to emit a signal. The signal received by the radiator may be transmitted to the power feeder, which in turn transmits the signal received by the power feeder to the radio frequency chip, allowing the electronic device to receive a signal.

[0009] The control chip is configured to be electrically connected to the first button via the first circuit board and to be electrically connected to the second button via the second circuit board. When the first button is pressed, the control chip can increase the volume of the electronic device, and when the second button is pressed, the control chip can decrease the volume of the electronic device.

[0010] Along the first direction, the two sides of the first circuit board are respectively connected to the first button and the device circuit board, and the two sides of the second circuit board are respectively connected to the second button and the device circuit board; along the second direction, the second direction is perpendicular to the first direction, the first button and the second button are spaced apart, the 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 feeding part are spaced apart, and the second circuit board and the feeding part are spaced apart.

[0011] As a result, the feeding portion is at least partially exposed relative to the first circuit board, and the feeding portion is also at least partially exposed relative to the second circuit board, thereby preventing the first circuit board from affecting the signal radiation intensity of the feeding portion, and preventing the second circuit board from affecting the signal radiation intensity of the feeding portion, so that the signal intensity radiated by the feeding portion is stronger, thereby improving the radiation intensity of the antenna.

[0012] In some embodiments, along the second direction, the spacing between the first circuit board and the feeder is at least 0.8 mm, and the spacing between the second circuit board and the feeder is at least 0.8 mm. This ensures sufficient clearance between the first circuit board and the feeder, and also between the second circuit board and the feeder, thereby enhancing the radiation performance of the feeder.

[0013] In some embodiments, the housing includes a frame and a support member, wherein the frame surrounds the outer periphery of the support member and is fixedly connected to the outer periphery of the support member; at least a portion of the support member forms the feeder, and at least a portion of the frame forms the radiator. The frame serves as the frame and exterior component of the mobile phone and can also serve as a radiator, saving components, simplifying assembly steps, increasing assembly efficiency, and enhancing the radiation intensity of the antenna. The feeder is integrally formed with the support member, which can increase the structural strength of the support member, save components, simplify assembly steps, and increase assembly efficiency. In addition, a portion of the frame serves as the radiator, so that at least a portion of the radiator can become the exterior surface of the mobile phone, that is, at least a portion of the radiator is exposed to the outside and is visible. This can prevent the radiator from occupying the internal space of the mobile phone and prevent other components inside the electronic device from blocking the radiator, thereby making the radiation intensity of the antenna stronger.

[0014] 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 pass through 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.

[0015] In related technologies, as mobile phones need to support more and more frequency bands, the corresponding number of 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 space on the support is set to the feeding part connected to the antenna, but the number of antennas still cannot meet the demand.

[0016] To address the aforementioned issues, this embodiment utilizes the area on the frame used for mounting the first and second keycaps. More specifically, the area on the first frame where the first and second keycaps are mounted is used to house the radiator. Furthermore, the area on the support member where the first and second key modules are mounted is used to house the feeder. This allows the radiator to be electrically connected to the RF chip on the device's circuit board through the feeder, thereby fulfilling the antenna function. This increases the number of antennas while preventing them from interfering with the phone's slim design.

[0017] 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.

[0018] In some embodiments, the first and second perforations are connected to form a through-hole, and the first and second keycaps are integrally formed. This facilitates processing and allows the first and second keycaps to be simultaneously installed in the through-hole, thereby increasing assembly efficiency and enhancing aesthetics.

[0019] In some embodiments, the radiator operates at medium and high frequencies, the length dimension of the through hole along the first direction is between 15 mm and 25 mm, and the width dimension of the through hole along 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, accordingly, in order for the first keycap and the second keycap to be smoothly installed in the through hole, the volume of the first keycap and the second keycap needs to be reduced, and 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, the volume of the radiator may be small, and the radiation performance of the radiator may be weakened. Setting the length dimension of the through hole between 15 mm and 25 mm and the width dimension of the through hole between 1.2 mm and 1.8 mm can not only make the through hole accommodate the first keycap and the second keycap that are easy for the user to operate, but also reduce the influence of the through hole on the radiation performance of the radiator.

[0020] In some embodiments, a storage portion and an accommodating portion are provided inside the shell, and along the first direction, the frame, the storage portion and the accommodating portion are arranged in sequence; the storage portion includes a first storage portion and a second storage portion, and along the second direction, the first storage portion, the feeding portion and the second storage portion are arranged in sequence; the first button is provided in the first storage portion, the second button is provided in the second storage portion, and the device circuit board is provided in the accommodating portion.

[0021] By arranging the receiving portion and the accommodating portion along the first direction, the first receiving portion, the power feeding portion, and the second receiving portion along the second direction, and then arranging the first button in the first receiving portion and the second button in the second receiving portion, the first button and the second button are separated by the power feeding portion along the second direction. As a result, the first circuit board can achieve the shortest distance connection between the first button and the device circuit board, while avoiding the power feeding portion, thus preventing interference between the first circuit board and the power feeding portion when connecting the first button and the device circuit board. The second circuit board can achieve the shortest distance connection between the second button and the device circuit board, while avoiding the power feeding portion, thus preventing interference between the second circuit board and the power feeding portion when connecting the second button and the device circuit board.

[0022] In some embodiments, the support member further comprises a connecting portion, wherein along the first direction, the frame, the connecting portion, and the feeding portion are sequentially connected; along the second direction, the surface of the first receiving portion, the surface of the connecting portion, and the surface of the second receiving portion are sequentially connected and flush to form a sealing surface; the electronic device further comprises a sealing member, one side surface of the sealing member being connected to the sealing surface. The sealing member may be foam, and when the electronic device is assembled, the back panel is fixed to the frame to seal the device circuit board and other components within the housing to prevent dust and other foreign matter from entering the housing.

[0023] In some embodiments, the first circuit board is a flexible circuit board, comprising a first connecting portion, a first flexible portion, and a second connecting portion connected in sequence; the first connecting portion is disposed in the first receiving portion, and the second connecting portion is disposed in the receiving portion; along the first direction, the first connecting portion and the first button are stacked and connected; along the third direction, the second connecting portion and the device circuit board are stacked and connected. The first connecting portion is configured to connect to the first button, and the second connecting portion is configured to connect to the device circuit board. The first flexible portion can deform to smoothly connect the first circuit board to the first button and the device circuit board, while occupying a relatively small space.

[0024] In this embodiment, the first circuit board is a flexible circuit board, and 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 shell. On the other hand, the first circuit board can be deformed, which can make the relative position of the radio frequency chip and the first button more flexible. Specifically, the first button and the first connecting part are stacked along the first direction, and the second connecting part and the device circuit board are stacked along the third direction. That is, no matter how the relative position of the radio frequency chip and the first button changes, the electrical connection between the radio frequency chip and the first button can be achieved through the deformation of the first circuit board. In addition, the first circuit board can be deformed, and it can also make the first circuit board fit the corresponding part of the first shell, thereby reducing the space occupied by the first circuit board, increasing the structural compactness of the assembled first button module, and further saving the internal space of the first shell.

[0025] In some embodiments, the first receiving portion is provided with a first receiving groove, and the first connecting portion and the first button are both disposed within the first receiving groove. The electronic device further comprises a first reinforcing plate disposed within the first receiving groove, the first reinforcing plate having a surface laminated and connected to a surface of the first connecting portion facing away from the first button, and the surface of the first reinforcing plate facing away from the first connecting portion being fixed to a side surface of the first receiving groove. The first reinforcing plate is connected to the first connecting portion to support the first connecting portion and enhance its structural strength, thereby increasing the reliability of the connection between the first connecting portion and the first button.

[0026] In some embodiments, the first reinforcement plate is provided with a first positioning protrusion on one side of the notch of the first receiving groove, and the first receiving groove is provided with a first positioning groove on the side surface; the first positioning protrusion is fixed in the first positioning groove to limit the displacement of the first reinforcement plate along the second direction. The first button is located inside the housing, and the first keycap is installed on the corresponding 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 reinforcement plate in the second direction. The first button is fixed to the first reinforcement plate, so the first positioning protrusion simultaneously positions the first button in the second direction, thereby preventing the first button and the first keycap from being misaligned 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.

[0027] In some embodiments, the first reinforcement plate has a second positioning protrusion protruding from one side of the bottom surface of the first receiving slot, the bottom surface of the first receiving slot is provided with a first positioning hole, and the wall surface of the first positioning hole is recessed with a second positioning groove. The second positioning protrusion extends into the first positioning hole and is fixed in the second positioning groove to limit displacement of the first reinforcement plate along the third direction. This prevents misalignment of the first key and the first keycap along the third direction, improves the positional accuracy of the first key and the first keycap along the third direction, and enhances smoothness when pressing the first keycap.

[0028] In some embodiments, the first reinforcing plate further includes a first gripping protrusion on one side of the notch of the first receiving slot, the first gripping protrusion extending out of the first receiving slot. When assembling the first button, the first connecting portion of the first circuit board, and the first reinforcing plate into the first receiving slot, the operator can hold the first gripping protrusion and install the first reinforcing plate into the first receiving slot from the notch of the first receiving slot. 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 into the first receiving slot along with the first reinforcing plate. After assembly is complete, the first gripping protrusion is at least partially located outside the first receiving slot. The operator can then break the first gripping protrusion off the first reinforcing plate, separating the first gripping protrusion from the first reinforcing plate. Thus, during installation, the operator can hold the first gripping protrusion. Once installation is complete, the first gripping protrusion is broken off, preventing the first gripping protrusion from occupying space and interfering with the assembly of other components.

[0029] In some embodiments, the housing portion includes a housing cavity, the bottom surface of which is recessed with a first housing groove. The device circuit board is disposed within the housing cavity, and the second connecting portion is disposed within the first housing groove. The placement of the second connecting portion within the first housing groove fully utilizes the space within the housing and prevents the second connecting portion from protruding and pressing against the device circuit board, thereby increasing the stability of the device circuit board and ensuring smooth connection between the second connecting portion and the device circuit board.

[0030] In some embodiments, the electronic device further includes a second reinforcing plate disposed within the first receiving groove and laminated to a surface of the second connecting portion facing away from the device circuit board. The second reinforcing plate supports and reinforces the second connecting portion, facilitating installation of the second connecting portion within the first mounting groove and enhancing the stability of the connection between the second connecting portion and the device circuit board.

[0031] In some embodiments, the second circuit board is a flexible circuit board, comprising 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 receiving portion, and the fourth connecting portion is disposed in the receiving portion; along the first direction, the third connecting portion is stacked and connected to the second button; along the third direction, the fourth connecting portion is stacked and connected to the device circuit board. The third connecting portion is configured to connect to the second button, and the fourth connecting portion is configured to connect to the device circuit board. The second flexible portion is deformable to facilitate connection of the second circuit board to the second button and the device circuit board, while occupying a relatively small space.

[0032] The second circuit board is a flexible circuit board, which is used to connect the second button and the RF chip of the device circuit board. The second circuit board is thin, which can reduce the volume of the second button module to save the internal space of the first shell. The second circuit board can be deformed, which can make the relative position of the RF chip and the second button more flexible, specifically making the third connecting part and the second button stacked along the first direction, and the fourth connecting part and the device circuit board stacked along the third direction. That is, no matter how the relative position of the RF chip and the second button changes, the electrical connection between the RF chip and the second button can be achieved through the deformation of the second circuit board. In addition, the second circuit board can be deformed, which can also make the second circuit board fit the corresponding part of the first shell, thereby reducing the space occupied by the second circuit board, increasing the structural compactness of the second button module after assembly, and further saving the internal space of the first shell.

[0033] In some embodiments, the second receiving portion is provided with a second receiving groove, and the third connecting portion and the second button are both disposed within the second receiving groove. The electronic device further comprises a third reinforcing plate disposed within the second receiving groove, the third reinforcing plate having a surface laminated and connected to a surface of the third connecting portion facing away from the second button, and the surface of the third reinforcing plate facing away from the third connecting portion being 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.

[0034] In some embodiments, the third reinforcing plate is provided with a third positioning protrusion on one side of the notch of the second receiving slot, and a third positioning groove is recessed on the side of the second receiving slot; the third positioning protrusion is fixed within the third positioning groove to limit displacement of the third reinforcing plate in the second direction. A second button is located within the housing, and a second keycap is mounted on the corresponding frame of the housing. The second keycap is configured to be pressed by a user. The pressing force acts on the second button via the second keycap, and the signal generated by the second button is transmitted to the control chip via the second circuit board. Upon 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, so the second positioning protrusion simultaneously positions the second button in the second direction, thereby preventing misalignment of the second button and keycap in the second direction, increasing the positional accuracy of the second button and keycap in the second direction, and enhancing the smoothness of pressing the second keycap.

[0035] In some embodiments, the third reinforcing plate has a fourth positioning protrusion on one side facing the bottom of the second receiving slot, the second receiving slot has a second positioning hole on the bottom, and the wall of the second positioning hole has a fourth positioning groove. The fourth positioning protrusion extends into the second positioning hole and is fixed in the fourth positioning groove to limit displacement of the third reinforcing plate along the third direction. This prevents misalignment of the second key and the second keycap along the third direction, increases the positional accuracy of the second key and the second keycap along the third direction, and improves the smoothness of pressing the second keycap.

[0036] In some embodiments, the third reinforcing plate further includes a second gripping protrusion on one side of the notch of the second receiving slot, the second gripping protrusion extending out of the second receiving slot. When assembling the second button, the third connecting portion of the second circuit board, and the third reinforcing plate into the second receiving slot, the operator can hold the second gripping protrusion and install the third reinforcing plate into the second receiving slot from the notch of the second receiving slot. Since the second button and the third connecting portion are both fixedly connected to the third reinforcing plate, the second button and the third connecting portion are installed together with the third reinforcing plate into the second receiving slot. After assembly is complete, the second gripping protrusion is at least partially located outside the second receiving slot. The operator can then break the second gripping protrusion off the third reinforcing plate, separating the second gripping protrusion from the third reinforcing plate. Thus, the operator can hold the second gripping protrusion during installation. After installation is complete, the second gripping protrusion is broken off, preventing the second gripping protrusion from occupying space and interfering with the assembly of other components.

[0037] In some embodiments, the accommodating portion includes an accommodating cavity, the bottom surface of which is recessed with a second accommodating groove. The device circuit board is disposed within the accommodating cavity, and the fourth connecting portion is disposed within the second accommodating groove. Placing the fourth connecting portion within the second accommodating groove fully utilizes the space within the housing and prevents the fourth connecting portion from protruding and pressing against the device circuit board, thereby increasing the stability of the device circuit board while ensuring smooth connection between the fourth connecting portion and the device circuit board.

[0038] In some embodiments, the electronic device further includes a fourth reinforcing plate disposed within the second receiving groove and laminated to a surface of the fourth connecting portion facing away from the device circuit board. The fourth reinforcing plate supports and reinforces the fourth connecting portion, facilitating installation of the fourth connecting portion within the second mounting groove and enhancing the stability of the connection between the fourth connecting portion and the device circuit board.

[0060] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0061] An embodiment of the present application provides an electronic device, which includes but is not limited to a cell phone, a foldable cell phone, a notebook computer, a tablet personal computer, a personal digital assistant, a wearable device, or a mobile device, etc. The wearable device may specifically be a wearable watch, a wearable bracelet, etc.

[0062] In the embodiments of the present application, an electronic device is taken as an example of a foldable mobile phone.

[0063] Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of a first state of a mobile phone 1000 provided in an embodiment of the present application, and Figure 2 is a schematic diagram of a second state of a mobile phone 1000 provided in an embodiment of the present application.

[0064] The foldable mobile phone 1000 shown in FIG1 is in a folded state, and the foldable mobile phone 1000 shown in FIG2 is in an unfolded state. The unfolding angle of the foldable mobile phone 1000 shown in FIG2 is 180 degrees. It should be noted that the angles illustrated in the embodiments of the present application are allowed to have slight deviations. For example, the unfolding angle of the foldable mobile phone 1000 shown in FIG2 is 180 degrees, which means that it can be 180 degrees or 180±10 degrees. The angles illustrated in the following text can be understood in the same way.

[0065] For ease of description, the length of the foldable phone 1000 is defined as the X-axis direction (first direction), the width of the foldable phone 1000 is defined as the Y-axis direction (second direction), and the thickness of the foldable phone 1000 is defined as the Z-axis direction (third direction). The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other. In other embodiments, the first direction may be the Y-axis direction, and the second direction may be the X-axis direction.

[0066] It should be noted that the directional terms such as "top", "bottom", "left", "right", "front" and "back" used in the embodiment of the present application to describe the mobile phone 1000 are mainly explained based on the display orientation of the mobile phone 1000 in Figure 2, with the direction facing the positive Z-axis as "top" and "up", the direction facing the negative Z-axis as "bottom" and "back", the direction facing the positive X-axis as "right", the direction facing the negative X-axis as "left", the direction facing the positive Y-axis as "back", and the direction facing the negative Y-axis as "front". It does not constitute a limitation on the orientation of the mobile phone 1000 in actual application scenarios.

[0067] The foldable mobile phone 1000 includes a main body 1100 and a display screen 1200, which is mounted on the main body 1100. The display screen 1200 includes a display surface and a mounting surface, which 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 portion 1210, a second display portion 1220, and a third display portion 1230. The third display portion 1230 is located between the first display portion 1210 and the second display portion 1220. The third display portion 1230 is flexible and can be bent along the X-axis. The first display portion 1210 and the second display portion 1220 are actually also bendable when not fixed. The direction in which the display screen 1200 displays the image can be parallel to the X-axis direction or the Y-axis direction.

[0068] In this embodiment, the display screen 1200 uses a flexible display screen 1200, for example, an organic light-emitting diode (OLED) display screen 1200, an active-matrix organic light-emitting diode or active-matrix organic light-emitting diode (AMOLED) display screen 1200, a mini organic light-emitting diode (MID) display screen 1200, a micro organic light-emitting diode (MID) display screen 1200, a micro organic light-emitting diode (MID) display screen 1200, or a quantum dot light-emitting diode (QLED) display screen 1200.

[0069] 1 and 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 expanded or folded.

[0070] In this embodiment, the rotation mechanism 700 can be a hinge. The rotation mechanism 700 is connected between the first shell 500 and the second shell 600, which is equivalent to the rotation structure between the first shell 500 and the second shell 600, so as to enable the first shell 500 and the second shell 600 to rotate freely relative to each other and fold relative to each other. Specifically, the rotation mechanism 700 includes two connected hinges, which are arranged in sequence along the Y-axis, with one hinge connected to the first shell 500 and the other hinge connected to the second shell 600; alternatively, the rotation mechanism 700 includes a hinge that extends from one side of the mobile phone 1000 to the other side along the Y-axis. In other embodiments, the rotation mechanism 700 is two connected and relatively rotatable shafts, one of which is rotatably connected to the first shell 500 and the other is rotatably connected to the second shell 600, so as to enable the first shell 500 and the second shell 600 to rotate relative to each other. In other embodiments, the rotating mechanism 700 may also be a rotating structure of other structures, as long as the first shell 500 and the second shell 600 can be freely rotated and folded relative to each other without damaging the display screen 1200.

[0071] The display screen 1200 is stacked between the first housing 500, the second housing 600, and the rotating mechanism 700. The first display portion 1210 faces the first housing 500, the second display portion 1220 faces the second housing 600, and the third display portion 1230 faces the rotating mechanism 700. When the first and second housings 500, 600 are unfolded relative to each other, the first and second housings 500, 600 are arranged side by side along the Y-axis, with an angle of 180 degrees between them. The display screen 1200 is in the unfolded state, and the rotating mechanism 700 is housed within the first and second housings 500, 600. When the first and second housings 500, 600 are folded relative to each other, the first and second housings 500, 600 are stacked along the Z-axis, with an angle of 0 degrees between them. The display screen 1200 is in the folded state, and a portion of the rotating mechanism 700 is exposed and located between the first and second housings 500, 600, serving as the exterior component of the mobile phone 1000. When the included angle between the first shell 500 and the second shell 600 is 180 degrees and 0 degree, an assembly tolerance angle range is allowed to exist. For example, 180 degrees can be understood as 179 degrees, and 0 degree can be understood as 1 degree.

[0072] Please refer to Figure 3, which is a schematic diagram of the structure of the first housing 500 of the mobile phone shown in Figure 2. In this embodiment, the mobile phone 1000 also includes a first button module 100, a second button module 200, an antenna 300, and a device circuit board 400. The first button module 100, the second button module 200, the antenna 300, and the device circuit board 400 are all disposed in the first housing 500 or the second housing 600. For example, the first button module 100, the second button module 200, the antenna 300, and the device circuit board 400 are all disposed in the first housing 500. The device circuit board 400 can be the mainboard of the mobile phone 1000. The device circuit board 400 integrates a radio frequency chip (not shown) and a control chip (not shown). The control chip can be the central processing unit of the mobile phone 1000. The antenna 300 can be an antenna 300 that supports 4G or 5G frequency bands. The antenna 300 is electrically connected to the radio frequency chip to enable the mobile phone 1000 to receive or transmit signals. In this embodiment, the first button module 100 can be a volume-up module, and the second button module 200 can be a volume-down module. The first button module 100 is electrically connected to the control chip. When a user operates the first button module 100, the control chip receives a signal from the first button module 100 and controls the volume of the mobile phone 1000 to increase. The second button module 200 is electrically connected to the control chip. When a user operates the second button module 200, the control chip receives a signal from the second button module 200 and controls the volume of the mobile phone 1000 to decrease.

[0073] In other embodiments, the first button module 100 may be a volume reduction module, and the second button module 200 may be a volume increase module. Alternatively, the first button module 100 may be a power button module, and the second button module 200 may be a volume reduction module.

The frame 530 is fixedly connected to the periphery of the support member 540. The frame 530 is located on the negative Z-axis side and is flush with the second surface 542 of the support member 540 to facilitate supporting the display screen 1200. The side of the frame 530 located on the positive Z-axis side is raised relative to the first surface 541 of the support member 540, so that the frame 530 and the support member 540 enclose a storage space (not shown). The storage space is used to accommodate components such as the first button module 100, the second button module 200, and the device circuit board 400. The first back plate 520 is fixed to the side of the frame 530 located on the positive Z-axis side to enclose the storage space.

[0075] The frame 530 includes a first frame 531, a second frame 532 and a third frame 533. The first frame 531 and the third frame 533 are opposite to each other along the X-axis direction. The first frame 531 and the third frame 533 are the two long sides of the frame 530; the second frame 532 is connected between the first frame 531 and the third frame 533. The second frame 532 is the short side of the frame 530. The side of the frame 530 opposite to the second frame 532 along the Y-axis direction is used to accommodate the rotating mechanism 700.

[0076] Please refer to Figure 4, which is a schematic diagram of the partial structure of the first middle frame shown in Figure 3. The support member 540 includes a storage portion 550 and a receiving portion 560. The storage portion 550 is connected to the first frame 531, and the receiving portion 560 is connected to the side of the storage portion 550 away from the first frame 531. In other words, along the X-axis direction, the first frame 531, the storage portion 550 and the receiving portion 560 are arranged in sequence. Specifically, the storage portion 550 includes a first storage portion 570 and a second storage portion 580. Along the Y-axis direction, the first storage portion 570 and the second storage portion 580 are arranged at intervals.

[0077] The first receiving portion 570 may be in the shape of an elongated strip, with its length parallel to the Y-axis. The first receiving portion 570 may be formed as a protrusion from the first surface 541. The first receiving portion 570 is provided with a first receiving groove 571, a first positioning groove 572, and a first avoidance groove 575. The first receiving groove 571 and the first positioning groove 572 are both recessed on the side of the first receiving portion 570 facing away from the first surface 541. The first positioning groove 572 also extends through the side of the first receiving groove 571. The first avoidance groove 575 is recessed on the side of the first receiving portion 570 facing away from the first surface 541. The first avoidance groove 575 also extends through the side of the first receiving groove 571 and the side of the first receiving groove 570 facing away from the first frame 531. The first receiving groove 571 is used to install some components of the first button module 100 , the first positioning groove 572 is used to position the first button module 100 , and the first avoiding groove 575 is used to avoid some components of the first button 110 assembly.

[0078] The second receiving portion 580 can be in the shape of an elongated strip, with the length direction of the second receiving portion 580 parallel to the Y-axis direction. The second receiving portion 580 can be formed as a protrusion from the first surface 541. The second receiving portion 580 is provided with a second receiving groove 581, a third positioning groove 582, and a second avoidance groove 585. The second receiving groove 581 and the third positioning groove 582 are both recessed on the side of the second receiving portion 580 facing away from the first surface 541, and the depth and length of the second receiving groove 581 are respectively greater than the depth and length of the third positioning groove 582. The third positioning groove 582 also passes through the side surface of the second receiving groove 581. The second avoidance groove 585 is recessed on the side of the second receiving portion 580 facing away from the first surface 541, and the second avoidance groove 585 also passes through the side surface of the second receiving groove 581 and the side of the second receiving portion 580 facing away from the first frame 531.

[0079] Referring to Figure 4, along the Y-axis, a connecting portion 590 is provided between the first receiving portion 570 and the second receiving portion 580. The connecting portion 590 protrudes from the first surface 541. Along the X-axis, the connecting portion 590 is connected to the first frame 531, and the width of the connecting portion 590 is smaller than the width of the first receiving portion 570, which is also smaller than the width of the second receiving portion 580. In other words, the first receiving portion 570, the connecting portion 590, and the second receiving portion 580 enclose a U-shaped space. The thickness of the first receiving portion 570, the second receiving portion 580, and the connecting portion 590 are substantially the same, so that the first receiving portion 570 can support the sealing member. Specifically, the surface of the connecting portion 590 facing away from the first surface 541, the surface of the first receiving portion 570 facing away from the first surface 541, and the surface of the second receiving portion 580 facing away from the first surface 541 are sequentially connected and flush along the Y-axis to form a sealing surface. The sealing surface is used to set a sealing member (not shown). It is understood that the sealing member is bonded between the sealing surface and the first back plate 520 by adhesive to seal the gap between the sealing surface and the first back plate 520 to prevent foreign matter such as dust and water vapor from entering the receiving cavity. In this embodiment, the sealing member can be foam.

[0080] The accommodating portion 560 is the portion of the support member 540 located to the right of the receiving portion 550. The accommodating portion 560 is provided with a receiving cavity (not shown) for mounting the device circuit board 400. The bottom surface of the accommodating cavity is provided with a first receiving groove 561 and a second receiving groove 562. The first receiving groove 561 is located to the right of the first receiving portion 570, and the second receiving groove 562 is located to the right of the second receiving portion 580. The first receiving groove 561 is used to mount some components of the first key module 100, while the second receiving groove 562 is used to mount some components of the second key module 200.

[0081] Please refer to FIG. 4 and FIG. 5 . FIG. 5 is a schematic diagram of a partial structure of the first middle frame shown in FIG. 3 from another perspective.

[0082] In this embodiment, the first receiving portion 570 further comprises a first positioning hole 573 and a second positioning groove 574. The first positioning hole 573 extends through the second surface 542 and the bottom surface of the first receiving groove 571. The second positioning groove 574 is recessed in the wall surface of the first positioning hole 573 and extends through the second surface 542. The first positioning hole 573 and the second positioning groove 574 are used to position the first button module 100.

[0083] The second receiving portion 580 further defines a second positioning hole 583 and a fourth positioning groove 584. The second positioning hole 583 extends through the second surface 542 and the bottom surface of the second receiving groove 581. The fourth positioning groove 584 is recessed into the wall of the second positioning hole 583 and extends through the second surface 542. The second positioning hole 583 and the fourth positioning groove 584 are used to position the second button module 200.

[0084] It can be understood that the above-mentioned first receiving groove 571, first positioning groove 572, first positioning hole 573, second positioning groove 574, first avoidance groove 575, second receiving groove 581, third positioning groove 582, second positioning hole 583, fourth positioning groove 584, second avoidance groove 585, accommodating cavity, first accommodating groove 561, second accommodating groove 562, etc. are all part of the accommodating space.

[0085] FIG6 is a schematic diagram of a partial structure of the mobile phone 1000 shown in FIG2 . In this embodiment, the antenna 300 includes a feeder 310, a radiator 320, and a spring (not shown). The feeder 310 may be a portion of the support member 540, that is, a portion of the support member 540 constitutes the feeder 310, or in other words, the feeder 310 is integrally formed with the first housing 500. More specifically, the feeder 310 may be integrally formed with the support member 540. Thus, no additional components are required to serve as the feeder 310, reducing the number of components in the mobile phone 1000 and avoiding the need to assemble the feeder 310, thereby simplifying the assembly steps and increasing assembly efficiency. Specifically, the feeder 310 may be a portion of the support member 540 located between the first receiving portion 570 and the second receiving portion 580, and the feeder 310 is sunken relative to the first receiving portion 570 and the second receiving portion 580, with the thickness of the first receiving portion 570 and the second receiving portion 580 both being greater than the thickness of the feeder 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 a U-shaped space enclosed by the first receiving portion 570 , the connecting portion 590 and the second receiving portion 580 .

[0086] In this embodiment, the surface of the feeding portion 310 facing away from the first surface 541 is substantially flush with the surface of the device circuit board 400, so as to facilitate the connection between the feeding portion 310 and the device circuit board 400. This also includes processing errors.

[0087] The radiator 320 can be part of the frame 530, that is, a portion of the frame 530 constitutes the radiator 320, or in other words, the radiator 320 can be integrally formed with the first housing 500. More specifically, the radiator 320 can be integrally formed with the frame 530. Using a portion of the frame 530 as the radiator 320 eliminates the need for additional components to serve as the radiator 320, reducing the number of components in the mobile phone 1000 and eliminating the need to assemble the radiator 320, simplifying the assembly process and increasing assembly efficiency. It is understood that at least a portion of the connecting portion 590 can be made of conductive metal, serving as the radiator 320 to connect the power feeder 310 to the radiator 320. It is understood that the portions of the first midframe 510 that serve as the power feeder 310 and the radiator 320 are both made of conductive metal. The remaining portions of the first midframe 510 can be made of an insulating material such as plastic, or metal.

[0088] The radiator 320 may comprise a portion of the frame 530. Specifically, the radiator 320 may comprise a portion of the first frame 531. The portion of the first frame 531 that serves as the radiator 320 is made of conductive metal. Another portion of the first frame 531 comprises an insulating portion 534 (shown in FIG. 6 ), which is located between the support member 540 and the radiator 320. The length of the radiator 320 along the Y-axis may be designed based on the frequency band that the antenna 300 needs to support. In one embodiment, the radiator 320 needs to radiate signals in the mid- to high-frequency band, ranging from 1000 MHz to 3000 MHz. In this embodiment, the radiator length is approximately 1 / 4 of the wavelength of the signal being radiated. This is not a limitation in this embodiment. The thickness of the first frame 531 along the Z-axis is approximately the same as the thickness of the exterior of the mobile phone 1000. By using a portion of the first frame 531 as the radiator 320, the thickness of the radiator 320 may be approximately the same as the thickness of the exterior of the mobile phone 1000. Therefore, when the frequency band supported by the antenna 300 is the same, the length of the radiator 320 is basically fixed, but the thickness of the radiator 320 is thicker, and the volume of the radiator 320 is larger. The larger volume of the radiator 320 can make the radiation capability of the antenna 300 stronger.

[0089] In addition, the radiator 320 can be composed of a frame 530, and the frame 530 serves as an appearance component of the mobile phone 1000. Therefore, 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, thereby preventing the radiator 320 from occupying the internal space of the mobile phone 1000 and preventing other components inside the mobile phone 1000 from blocking the radiator 320, thereby making the radiation intensity of the antenna 300 stronger.

[0090] In this embodiment, the radiator 320 is provided with a first through-hole 321 and a second through-hole 322. Both the first through-hole 321 and the second through-hole 322 extend through the radiator 320 along the X-axis. The first through-hole 321 communicates with the first receiving groove 571, and the second through-hole 322 communicates with the second receiving groove 581. The first key module 100 includes a first keycap 130, and the second key module 200 includes a second keycap 230. The first through-hole 321 is used to mount the first keycap 130, and a portion of the first keycap 130 extends into the first receiving groove 571, allowing the first keycap 130 to connect to other components within the first receiving groove 571. The second through-hole 322 is used to mount the second keycap 230. Both the first keycap 130 and the second keycap 230 can be made of metal, which provides a good operating feel. The outer surfaces of the first keycap 130 and the second keycap 230 are provided with an insulating layer (not shown) to insulate the first keycap 130 and the second keycap 230, 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.

[0091] 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. This facilitates processing and facilitates the simultaneous installation of the first keycap 130 and the second keycap 230 in the through-hole 323, thereby increasing assembly efficiency and enhancing 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 components, and the first through-hole 321 and the second through-hole 322 can also be two independent holes.

[0092] In this embodiment, the length of the through-hole 323 along the Y-axis is between 15 mm and 25 mm. Specifically, the length of the through-hole 323 can be 15 mm, 18 mm, 21 mm, 24 mm, or 25 mm. The width of the through-hole 323 along the Z-axis is between 1.2 mm and 1.8 mm. Specifically, the width of the through-hole 323 can be 1.2 mm, 1.4 mm, 1.6 mm, or 1.8 mm. If the length or width of the through-hole 323 is too small, the volume of the first keycap 130 and the second keycap 230 must be reduced to ensure smooth installation of the through-hole 323. However, if the volume of the first keycap 130 and the second keycap 230 is too small, it may be difficult for the user to operate. If the length or width of the through-hole 323 is too large, the volume of the radiator 320 may be reduced, thereby weakening the radiation performance of the radiator 320. The length of the through hole 323 is set between 15 mm and 25 mm, and the width of the through hole 323 is set between 1.2 mm and 1.8 mm. This allows the through hole 323 to accommodate the first keycap 130 and the second keycap 230 for easy user operation, while reducing the impact of the through hole 323 on the radiation performance of the radiator.

[0093] In the related art, as the mobile phone 1000 needs to support more and more frequency bands, the corresponding number of antennas 300 also increases, and the space required to set up the antennas 300 also becomes larger and larger. However, the increase in the number of antennas 300 runs counter to the trend of thinning and lightweight of the mobile phone 1000. In order to meet the number requirement of antennas 300, the part of the frame 530 of the mobile phone 1000 where other components are not set is also used as the radiator 320 of the antenna 300. Correspondingly, the vacant position on the support member 540 is set to the feeding part 310 connected to the antenna 300, but the number of antennas 300 still cannot meet the demand.

[0094] In this embodiment, to address the aforementioned issues, the area on the frame 530 used to mount the first keycap 130 and the second keycap 230 is also utilized. More specifically, the area of ​​the first frame 531 where the first and second keycaps 130 and 230 are mounted is used to mount the radiator 320. Simultaneously, the area of ​​the support member 540 where the first and second key modules 100 and 200 are mounted is used to mount the power feeder 310. This allows the radiator 320 to be electrically connected to the RF chip on the device circuit board 400 via the power feeder 310, thereby fulfilling the function of the antenna 300. This increases the number of antennas 300 while preventing the antennas 300 from interfering with the thin and lightweight design of the mobile phone 1000.

[0095] In this embodiment, one end of the shrapnel is connected to the RF chip, and the other end of the shrapnel is connected to the feed part 310, which is then connected to the radiator 320, so that the signal emitted by the RF chip can be transmitted to the radiator 320 through the shrapnel and the feed part 310 in sequence, and the radiator 320 then radiates the signal. After the feed part 310 receives the signal transmitted by the shrapnel, it can also directly radiate the signal. The signal received by the radiator 320 can also be transmitted to the RF chip through the feed part 310 and the shrapnel in sequence. In addition to receiving the signal transmitted by the radiator 320, the feed part 310 itself can also directly receive external signals. The signal directly received by the feed part 310 can also be transmitted to the RF chip through the shrapnel to realize the communication function of the mobile phone 1000.

[0096] Please refer to FIG. 7 and FIG. 8 . FIG. 7 is a partial structural diagram of the first button module 100 of the mobile phone 1000 shown in FIG. 2 , and FIG. 8 is a split structural diagram of the first button module 100 shown in FIG. 7 .

[0097] In this embodiment, the first key module 100 includes a first key 110, a first circuit board 120, a first keycap 130 (shown in FIG3 ), a first reinforcement plate 140, and a second reinforcement plate 160. The first circuit board 120 may be a flexible circuit board. In other embodiments, the first circuit board 120 may also be a rigid circuit board, a conductive member, or other device.

[0098] Along the X-axis, the first keycap 130, first button 110, and first circuit board 120 are connected in sequence. The side of the first circuit board 120 facing away from the first button 110 is connected to the control chip of the device circuit board 400. In other words, along the X-axis (first direction), the two sides of the first circuit board 120 are connected to the first button 110 and the device circuit board 400, respectively. In other embodiments, the first direction can also be the Y-axis. When a user presses the first keycap 130, the pressing force acts on the first button 110 through the first keycap 130. The signal generated by the first button 110 is transmitted to the control chip via the first circuit board 120. After receiving the signal, the control chip controls the volume of the mobile phone 1000 to increase. A first reinforcement plate 140 is connected to the portion where the first circuit board 120 connects to the first button 110 to support the portion where the first circuit board 120 connects to the first button 110 and enhance its structural strength. A second reinforcement plate 160 is connected to the portion where the first circuit board 120 connects to the device circuit board 400 to enhance its structural strength.

[0099] Please refer to FIG. 9 , which is a schematic structural diagram of the first circuit board 120 of the first key module 100 shown in FIG. 8 .

[0100] In this embodiment, the first circuit board 120 includes a first connecting portion 121, a first flexible portion 122, and a second connecting portion 123, which are sequentially connected along the X-axis. The first connecting portion 121 is used to connect to the first button 110, the first flexible portion 122 connects the first connecting portion 121 and the second connecting portion 123, and the second connecting portion 123 is used to connect to the device circuit board 400. The width of the first flexible portion 122 is smaller than that of the first connecting portion 121, which in turn is smaller than that of the second connecting portion 123. This ensures that the first connecting portion 121 can reliably connect to the first button 110, and the second connecting portion 123 can reliably connect to the device circuit board 400. The first flexible portion 122 can reliably connect to both the first connecting portion 121 and the second connecting portion 123. Furthermore, the smaller area of ​​the first flexible portion 122 reduces the space occupied by the first circuit board 120 and reduces material consumption.

[0101] Please refer to FIG. 10 , which is a schematic structural diagram of the first reinforcing plate 140 of the first button module 100 shown in FIG. 8 .

[0102] In this embodiment, the first reinforcing plate 140 includes a first long side 141 and a second long side 142. The first long side 141 is provided with a first positioning protrusion 143 and a first holding protrusion 144. The first positioning protrusion 143 includes a first extension 145 and a first positioning portion 146. One end of the first extension 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 145. The first positioning portion 146 and the first extension 145 are perpendicular to each other. In other words, the first extension 145 and the first positioning portion 146 form an L-shaped connection, with the end of the first extension 145 away from the first positioning portion 146 fixedly connected to the first long side 141. The first positioning portion 146 is configured to cooperate with the first receiving portion 570 to limit displacement of the first reinforcing plate 140 along the Y-axis.

[0103] In other embodiments, the first extending portion 145 and the first positioning portion 146 may not be perpendicular. For example, the angle between the first extending portion 145 and the first positioning portion 146 may be 70 degrees or 80 degrees.

[0104] In this embodiment, the first holding protrusion 144 is used to facilitate assembly of the first button module 100 to the first receiving portion 570. The first holding protrusion 144 includes a first holding portion 147, a first connecting leg 148, and a second connecting leg 149. The first holding portion 147 can be in the form 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 holding portion 147, and the first connecting leg 148 and the second connecting leg 149 are spaced apart. The end of the first connecting leg 148 away from the first holding portion 147 is fixedly connected to the first long side 141, and the end of the second connecting leg 149 away from the first holding 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, given the limited length of the first long side 141, the space on the first long side 141 is fully utilized to provide the first holding protrusion 144 and the first positioning protrusion 143, thereby enabling positioning of the first button module 100 along the Y-axis and facilitating assembly. In other embodiments, the first holding protrusion 144 may also have other shapes, such as a semi-circular shape, etc., without limitation, as long as it facilitates holding and avoids the first positioning protrusion 143.

[0105] It can be understood that the position of the first positioning protrusion 143 between the first connecting foot 148 and the second connecting foot 149 shown in Figure 10 is only exemplary. In fact, the first positioning protrusion 143 can also be connected to other positions of the first long side 141.

[0106] A second positioning protrusion 150 is provided on the second long side 142. The second positioning protrusion 150 includes a second extension 151 and a second positioning portion 152. One end of the second extension 151 is fixedly connected to the second long side 142, while the second positioning portion 152 is fixedly connected to the other end of the second extension 151. The second positioning portion 152 and the second extension 151 are perpendicular to each other. In other words, the second extension 151 and the second positioning portion 152 form an L-shaped connection, with the end of the second extension 151 distal from the second positioning portion 152 fixedly connected to the second long side 142. The second positioning portion 152 is configured to cooperate with the first receiving portion 570 to limit displacement of the second reinforcement plate 160 along the Z-axis. In this embodiment, there is one second positioning protrusion 150. In other embodiments, the number of second positioning protrusions 150 may be two, three, or the like. The second extension 151 and the second positioning portion 152 may also be non-perpendicular. For example, the angle between the second extension 151 and the second positioning portion 152 may be 73 degrees, 87 degrees, or the like. It can be understood that the position where the second positioning protrusion 150 is connected to the second long side 142 as shown in FIG. 10 is merely exemplary. In fact, the second positioning protrusion 150 may also be connected to other positions of the second long side 142 .

[0107] In this embodiment, the first button 110, the first connection portion 121 of the first circuit board 120, and the first reinforcement plate 140 are stacked in sequence. The first button 110 and the first connection portion 121 are fixedly connected to achieve electrical connection between the first button 110 and the first connection portion 121. The first connection portion 121 and the first reinforcement plate 140 are bonded and fixed together using adhesive. The second connection portion 123 of the first circuit board 120 and the second reinforcement plate 160 are stacked and bonded together using adhesive. The first reinforcement plate 140 supports and reinforces the first connection portion 121 and the first button 110, preventing the first connection portion 121 from deforming. The second reinforcement plate 160 supports and reinforces the second connection portion 123, preventing the second connection portion 123 from deforming. The first flexible portion 122 can deform so that the first connecting portion 121 and the second connecting portion 123 become perpendicular to each other, facilitating assembly of the first key module 100 to the first housing 500. The first flexible portion 122 of the first circuit board 120 is positioned between the second connecting pin 149 and the first positioning protrusion 143. In other words, the first connecting pin 148, the first flexible portion 122, the first positioning protrusion 143, and the second connecting pin 149 are arranged sequentially. This ensures that the first connecting pin 148, the first flexible portion 122, the first positioning protrusion 143, and the second connecting pin 149 do not interfere with each other within the limited space of the first long side 141, thereby enhancing the structural stability of the first key module 100. The first positioning protrusion 143 and the second positioning protrusion 150 are located on opposite sides of the first reinforcement plate 140, fully utilizing the space on the first reinforcement plate 140.

[0108] Please refer to FIG. 11 and FIG. 12 . FIG. 11 is a partial structural diagram of the second button module 200 of the mobile phone 1000 shown in FIG. 2 , and FIG. 12 is a split structural diagram of the second button module 200 shown in FIG. 11 .

[0109] The second button module 200 includes a second button 210, a second circuit board 220, a second keycap 230 (shown in Figure 3), a third reinforcement plate 240 and a fourth reinforcement plate 260. The structure of the second button module 200 is similar to that of the first button module. The structure and connection relationship of the components included in the second button module 200 can refer to the relevant description in the first button module. No further details will be given here. The difference between the second button module 200 and the first button module is that the second button module 200 can be used to control the volume reduction of the mobile phone. The difference between the second button module 200 and the first button module is also that the specific shape of the second circuit board 220 is different.

[0110] Please refer to FIG. 13 , which is a schematic structural diagram of the second circuit board 220 of the second key module 200 shown in FIG. 12 .

[0111] 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, which are sequentially connected along the X-axis. 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 that of the third connection portion 221, which is also smaller than that of the fourth connection portion 223. The second flexible portion 222 is L-shaped to facilitate electrical connection of the second button 210 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, and the 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 section 225 extends along the Y-axis, and the end of the second flexible section 225 away from the first flexible section 224 is connected to the fourth connection portion 223. This ensures that the third connection portion 221 can be reliably connected to the second button 210, and the fourth connection portion 223 can be reliably connected to the device circuit board 400. The second flexible section 222 can reliably connect to both the third connection portion 221 and the fourth connection portion 223. Furthermore, the second flexible section 222 has a smaller 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 section 222, and the fourth connection portion 223 can also have other shapes.

[0112] Please refer to FIG. 14 , which is a schematic structural diagram of the third reinforcing plate 240 shown in FIG. 12 .

[0113] The third reinforcing plate 240 includes a third long side 241 and a fourth long side 242. The third long side 241 is 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 extension portion 245 and a third positioning portion 246. The fourth long side 242 is provided with a fourth positioning protrusion 250. The fourth positioning protrusion 250 includes a fourth extension portion 251 and a fourth positioning portion 252. The structure, connection relationship, and function of each component of the third reinforcing plate 240 can be referred to the description of the first reinforcing plate.

[0114] Please refer to Figure 15, which is a schematic diagram of the assembled state of the mobile phone 1000 shown in Figure 2. As shown in Figure 15, the first holding protrusion 144 of the first reinforcing plate 140 is not broken off, and the second holding protrusion 244 of the third reinforcing plate 240 is not broken off.

[0115] When assembling mobile phone 1000, the operator holds first grip protrusion 144 and installs first reinforcement plate 140 into first receiving groove 571 through the notch of first receiving groove 571. Because first button 110 and first connecting portion 121 are both fixedly connected to first reinforcement plate 140, first button 110 and first connecting portion 121 are installed into first receiving groove 571 along with first reinforcement plate 140. During installation, the side of first button 110 facing away from first connecting portion 121 abuts against first keycap 130, and the side of first reinforcement plate 140 facing away from first connecting portion 121 is bonded to the side surface of first receiving groove 571 via adhesive. In other words, first keycap 130, first button 110, first connecting portion 121, and first reinforcement plate 140 are stacked and fixed in sequence along the X-axis.

[0116] 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 abuts against the bottom surface of the first positioning groove 572, thereby limiting the movement of the first reinforcing plate 140 along the Y-axis. This, in turn, limits the movement of the first button 110 and the first connecting portion 121 along the Y-axis. This prevents misalignment of the first button 110 and the first keycap 130 along the Y-axis, improves the positional accuracy of the first button 110 and the first keycap 130 along the Y-axis, and enhances the smoothness of pressing the first keycap 130.

[0117] Please refer to FIG. 16 , which is a structural diagram of a portion of the structure of the mobile phone 1000 shown in FIG. 15 from another perspective.

[0118] 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, thereby limiting the movement of the first reinforcement plate 140 along the Z-axis. This, in turn, limits the movement of the first button 110 and the first connecting portion 121 along the Z-axis. This prevents misalignment of the first button 110 and the first keycap 130 along the Z-axis, improves the positional accuracy of the first button 110 and the first keycap 130 along the Z-axis, and enhances the smoothness of pressing the first keycap 130.

[0119] The first holding protrusion 144 is at least partially located outside the first receiving groove 571 . The operator can then break the first holding protrusion 144 off the first reinforcing plate 140 to separate the first holding protrusion 144 from the first reinforcing plate 140 .

[0120] Please refer to Figures 17 and 18. Figure 17 is a schematic diagram of the partially assembled structure of the mobile phone 1000 shown in Figure 2, and Figure 18 is an enlarged schematic diagram of the structure at point A in Figure 17. As shown in Figures 17 and 18, the first gripping protrusion 144 of the first reinforcing plate 140 has been broken off. This allows the operator to hold the first gripping protrusion 144 during installation. Once installation is complete, the first gripping protrusion 144 is broken off, preventing it from occupying space and interfering with the assembly of other components.

[0121] Next, the operator can hold the second reinforcing plate 160 and the second connecting portion 123 and install them within the first receiving groove 561, such 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. The surface of the second reinforcing plate 160 facing away from the second connecting portion 123 can then be bonded to the bottom surface of the first receiving groove 561 using adhesive. Placing the second reinforcing plate 160 and the second connecting portion 123 within the first receiving groove 561 fully utilizes the space within the housing and prevents the second reinforcing plate 160 and the second connecting portion 123 from protruding and pressing against the device circuit board 400, thereby increasing the stability of the device circuit board 400 while ensuring smooth connection of the second connecting portion 123 to the device circuit board 400.

[0122] The second connection portion 123 and the first connection portion 121 can be perpendicular to each other through 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 connection portion 121 and is located in the first avoidance 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 storage portion 570 away from the first frame 531, and the second part of the first flexible portion 122 is parallel to the first connection portion 121. At this time, the second connection portion 123 is perpendicular to the first connection portion 121.

[0123] Please refer to Figures 17 and 19. Figure 19 is an enlarged schematic diagram of the structure at point B in Figure 17. Figures 17 and 19 show the state where the second key module 200 is installed. The process of installing the second key module 200 can be referred to the process of installing the first key module 100, and will not be repeated in this embodiment.

[0124] After the first button module 100 and the second button module 200 are installed, the device circuit board 400 can be installed in the accommodating cavity. The second connection portion 123 and the control chip are connected via a board-to-board connector, and the fourth connection portion 223 and the control chip are connected via a board-to-board connector. The feed portion 310 and the RF chip are connected using a spring clip.

[0125] After the first button module 100 and the second button module 200 are installed, a gap exists between the first circuit board 120 and the feeder 310, and a gap exists between the second circuit board 220 and the feeder 310, along the Y-axis direction (the second direction). This prevents the first circuit board 120 from affecting the signal radiation intensity of the feeder 310, and prevents the second circuit board 220 from affecting the signal radiation intensity of the feeder 310. Along the X-axis direction, a gap exists between the first circuit board 120 and the radiator 320, and a gap exists between the second circuit board 220 and the radiator 320. This prevents the first circuit board 120 from affecting the signal radiation intensity of the radiator 320, and prevents 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 the insulating portion 534 and the first receiving portion 570, and the second circuit board 220 and the radiator 320 can also be separated by the insulating portion 534 and the second receiving portion 580.

[0126] Furthermore, along the Y-axis, the spacing between the first circuit board 120 and the feed section 310 is at least 0.8 mm, and specifically can be 0.8 mm, 1 mm, or 1.2 mm, etc. The spacing between the second circuit board 220 and the feed section 310 is at least 0.8 mm, and specifically can be 0.8 mm, 0.9 mm, or 1.1 mm, etc. This ensures sufficient clearance between the first circuit board 120 and the feed section 310, and also between the second circuit board 220 and the feed section 310, thereby enhancing the radiation performance of the feed section 310.

[0127] The spacing between the first circuit board 120 and the radiator 320 is at least 0.8 mm, and can specifically be 0.8 mm, 1 mm, 1.3 mm, or 1.5 mm. The spacing between the second circuit board 220 and the radiator 320 is at least 0.8 mm, and can specifically be 0.8 mm, 0.9 mm, 1.1 mm, or 1.3 mm. This ensures sufficient clearance between the first circuit board 120 and the radiator 320, and also between the second circuit board 220 and the radiator 320, allowing the radiator 320 to better perform its radiation performance.

[0128] In this embodiment, a first circuit board 120 is used to connect the first button 110 and the RF chip on the device circuit board 400. The thickness of the first circuit board 120 ranges from 0.08 mm to 0.15 mm. This thinness reduces the volume of the first button module 100, conserving space within the first housing 500. Furthermore, the first flexible portion 122 is deformable, allowing for greater flexibility in the relative position of the RF chip and the first button 110. That is, regardless of the relative position of the RF chip and the first button 110, the deformation of the first flexible portion 122 maintains electrical connection between the RF chip and the first button 110. Furthermore, the deformation of the first flexible portion 122 allows it to conform to corresponding portions of the first housing 500, thereby reducing the space occupied by the first flexible portion 122 and increasing the compactness of the assembled first button module 100, further conserving space within the first housing 500.

[0129] Similarly, a second circuit board 220 is used to connect the second button 210 to the RF chip on the device circuit board 400. The thickness of the second circuit board 220 ranges from 0.08 mm to 1.5 mm. This thinness reduces the volume of the second button module 200, conserving space within the first housing 500. The second flexible portion 222 is deformable, allowing for flexible positioning of the RF chip and the second button 210. This means that regardless of the relative position of the RF chip and the second button 210, the electrical connection between the RF chip and the second button 210 can be achieved through the deformation of the second flexible portion 222. Furthermore, the deformation of the second flexible portion 222 allows it to conform to corresponding portions of the first housing 500, thereby reducing the space occupied by the second flexible portion 222 and increasing the compactness of the assembled second button module 200, further conserving space within the first housing 500.

[0130] Please refer to FIG. 20 , which is a schematic diagram of a portion of the internal structure of the first shell shown in FIG. 2 .

[0131] The device circuit board 400 and battery 800 are arranged along the Y-axis. The battery 800 is used to power the device circuit board 400 and other components. The first button 110 is located on the left side of the device circuit board 400. Therefore, a first flexible portion 122 extending along the X-axis is provided to electrically connect the first button 110 to the device circuit board 400 via the first circuit board 120. The second button 210 is located on the left side of the battery 800. Therefore, the second flexible portion 222 is L-shaped. 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, while the second flexible segment 225 extends along the Y-axis. This allows the second circuit board 220 to avoid the battery 800 and connect to the device circuit board 400, thus electrically connecting the second button 210 to the device circuit board 400 via the second circuit board 220.

[0132] The above are only some of the embodiments and implementations of this application. The scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
