Description

Technical Field

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

[0002] With the continuous development of consumer electronic products, full-screen products are favored by users, and increasing the screen-to-body ratio of electronic products has become the focus of research and development of manufacturers. At present, most lifting functional devices are used to increase the screen-to-body ratio of electronic products. However, the use of lifting functional devices requires a separate design of flexible circuit boards to ensure electrical connections, which makes it impossible to use lifting functional devices in a standardized manner with existing non-lifting functional devices, increasing the production cost of electronic products. Summary of the invention

[0003] The purpose of the present application is to provide an electronic device for normalizing the use of functional devices with existing non-lifting functional devices, which is beneficial to reducing the production cost of the electronic device and improving product competitiveness.

[0004] The electronic device provided in the present application includes a frame, a middle plate, a circuit board, a driving mechanism, a support member, a functional device, a first connector and a second connector; the frame is provided with a through hole, the through hole connects the inside and the outside of the frame; the middle plate is located inside the frame and fixedly connected to the frame, the circuit board is located inside the frame and fixed to the middle plate; the first connector is fixed to the circuit board and electrically connected to the circuit board; the driving mechanism is located inside the frame and fixed to the frame or the middle plate or the circuit board, and electrically connected to the circuit board, the support member is fixed to the driving mechanism, the functional device is fixed to the support member, and the driving mechanism is used to drive the support member to move so that the functional device extends or retracts from the through hole relative to the frame; the second connector is fixed to the support member and electrically connected to the functional device, when the functional device extends relative to the frame, the second connector is connected to the first connector, and when the functional device retracts relative to the frame, the second connector is disconnected from the first connector.

[0005] The electronic device shown in the present application uses a first connector and a second connector to realize the electrical connection between the functional device and the circuit board. When the driving mechanism drives the support member to move so that the functional device extends relative to the frame, the first connector and the second connector are connected, the functional device is electrically connected to the circuit board, and the electrical signal of the circuit board can be transmitted to the functional device; when the driving mechanism drives the support member to move so that the functional device retracts relative to the frame, the first connector is disconnected from the second connector, and the functional device is disconnected from the circuit board. Compared with traditional lifting functional devices, the electronic device shown in the present application does not need to use FPC to maintain the electrical connection state of the functional device, and there is no need to design different FPCs for different electronic devices. The functional device used in the electronic device shown in the present application can be used in a standardized manner with other non-lifting functional devices, saving the cost of the electronic device and improving the competitiveness of the electronic device.

[0006] Moreover, not using FPC to maintain the electrical connection state of the functional device ensures that the movement trajectory of the functional device relative to the frame is controllable, avoiding the friction and folding of the FPC during the extension or retraction of the functional device relative to the frame, or the fatigue and fracture of the internal wiring of the FPC due to multiple folding and stretching of the FPC, thereby ensuring the reliability of the functional device during use.

[0007] The interior of the frame refers to the entire inner cavity of the electronic device, which is used to house internal components of the electronic device such as the battery, memory card, speaker and receiver.

[0008] In one embodiment, the movement direction of the functional device when it is extended relative to the frame is the same as the movement direction of the second connector toward the first connector; the movement direction of the functional device when it is retracted relative to the frame is the same as the movement direction of the second connector away from the first connector, so that when the driving mechanism drives the support member to move to drive the functional device to move relative to the frame, it also drives the second connector to move relative to the first connector, ensuring that the second connector is connected to the first connector when the functional device is extended relative to the frame, and the second connector is disconnected from the first connector when the functional device is retracted relative to the frame.

[0009] In one embodiment, the support member is a rigid circuit board, which not only effectively supports the functional device and the second connector fixed to the support member, but also ensures the stability of the support member fixed to the driving mechanism. The support member is electrically connected between the functional device and the second connector. That is, the functional device is electrically connected to the second connector through the wiring embedded in the support member, and there is no need to electrically connect the functional device to the second connector through external wiring, thereby improving the neatness of the interior of the frame.

[0010] In one embodiment, the support member includes a first part and a second part connected to the edge of the first part, the first part is fixedly connected to the driving mechanism, the second part is fixedly connected to the functional device, the second connector is fixed to the first part and is located between the functional device and the driving mechanism, and the second connector is close to the driving mechanism. When the driving mechanism drives the support member to move, the movement trajectory of the second connector is more precise and controllable, ensuring the precise contact and connection between the second connector and the first connector.

[0011] In one embodiment, the support member includes a first part and a second part connected to the edge of the first part, the first part is fixedly connected to the driving mechanism, the second connector is fixed to the first part and is spaced apart from the driving mechanism, the second part is located between the second connector and the driving mechanism, and the functional device is fixed to the second part. In this case, the functional device is located between the second connector and the driving mechanism, the functional device is close to the driving mechanism, and when the driving mechanism drives the support member to move, the motion trajectory of the functional device is more accurately controllable, ensuring that the functional device can accurately extend or retract from the through hole relative to the frame.

[0012] In one embodiment, the electronic device further comprises a fixed shell, the fixed shell is fixed to the second part, and the functional device is installed inside the fixed shell, so as to confine the functional device inside the fixed shell, prevent the functional device from falling out from the fixed shell, and improve the assembly stability of the functional device. The fixed shell is slidably connected to the frame, that is, when the driving mechanism drives the support member to move, the fixed shell can extend or retract from the through hole relative to the frame.

[0013] In one embodiment, a seal is provided on the outer surface of the fixed shell. When the fixed shell is retracted relative to the frame, the seal is clamped between the fixed shell and the frame to prevent moisture or other impurities outside the frame from entering the interior of the frame, thereby improving the sealing of the electronic device.

[0014] In one embodiment, the circuit board includes a first circuit board and a second circuit board connected to the first circuit board. The first circuit board and the second circuit board together enclose an installation space. The driving mechanism, the supporting member and the functional device are all installed in the installation space to reduce the thickness of the assembly structure of the driving mechanism, the supporting member, the functional device and the circuit board in the electronic device, which is conducive to the lightweight design of the electronic device.

[0015] In one embodiment, the circuit board is a mainboard of an electronic device.

[0016] In one embodiment, when the functional device is retracted relative to the frame, the support member and the first circuit board are arranged side by side in the thickness direction of the electronic device, which not only avoids the influence of the movement of the support member on the electronic components arranged on the first circuit board and improves the reliability of the electronic device, but also simplifies the assembly structure of the support member and the first circuit board. Alternatively, the support member and the first circuit board are arranged partially overlapping in the thickness direction of the electronic device. At this time, the volume of the first circuit board is not limited, and more electronic components can be arranged on the first circuit board, thereby improving the integration of the electronic device. Moreover, the internal wiring can still be arranged in the overlapping area of ​​the first circuit board and the support member, and the space of the first circuit board can be fully utilized.

[0017] In one embodiment, the first circuit board and the second circuit board are both fixed to the middle plate, so as to fix the first circuit board and the second circuit board inside the frame, thereby ensuring the assembly stability of the first circuit board and the second circuit board inside the frame. The electronic device also includes a processor, the processor is fixed to the first circuit board, and the first connector is fixed to the second circuit board.

[0018] Wherein, the processor is electrically connected to the first connector.

[0019] In one embodiment, the second circuit board is electrically connected to the first circuit board, and the first connector is electrically connected to the processor via wiring embedded in the second circuit board and the first circuit board.

[0020] In one embodiment, the first circuit board and the second circuit board are both rigid circuit boards, and the first circuit board and the second circuit board are electrically connected via an electrical connector such as a plug-in connector.

[0021] In one embodiment, the first circuit board is a rigid circuit board and the second circuit board is a flexible circuit board, which can not only avoid the heterogeneous design of the circuit board and simplify the molding process of the circuit board, but also simplify the space occupied by the circuit board inside the frame, which is conducive to improving the space utilization inside the frame.

[0022] In one embodiment, the functional device is a camera module or a fingerprint recognition module. The camera module can be used for taking pictures, or for physiological feature recognition such as pupil recognition or facial recognition.

[0023] In one embodiment, the frame includes an upper frame and a lower frame that are arranged relatively to each other. When a user uses the electronic device, the upper frame is generally facing upward and the lower frame is generally facing downward. A through hole is provided in the middle of the upper frame. When the functional device extends out of the frame from the through hole, it is convenient for the user to directly use the functional device without adjusting the angle of the electronic device, thereby improving the user's experience.

[0039] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0040] See also Figure 1 and Figure 2 . Figure 1 It is a structural diagram of an electronic device 100 provided in an embodiment of the present application. Figure 2 yes Figure 1 A schematic diagram of a partial exploded structure of an electronic device 100 is shown.

[0041] The electronic device 100 may be an electronic product such as a tablet computer, a mobile phone, a camera, a personal computer, a laptop computer, a vehicle-mounted device, a wearable device, AR (Augmented Reality) glasses, an AR helmet, VR (Virtual Reality) glasses or a VR helmet. Figure 1 The electronic device 100 of the embodiment shown is described by taking a mobile phone as an example. Figure 1 As shown, the width direction of the electronic device 100 is defined as the X direction, the length direction of the electronic device 100 is defined as the Y direction, the thickness direction of the electronic device 100 is defined as the Z direction, and the X direction, the Y direction and the Z direction are perpendicular to each other.

[0042] The electronic device 100 includes a screen 11, a housing 12, a circuit board 20, a processor 30, a driving mechanism 40, a support member 50, a functional device 60, a first connector 70, a second connector 80 and a battery 90. The screen 11 is mounted on the housing 12. The housing 12 includes a frame 13, a back cover 14 and a middle plate 15, and the frame 13 is connected to the edge of the back cover 14. The frame 13 is provided with a through hole (not shown), which connects the inside and outside of the frame 13 so that the functional device 60 can extend or retract from the through hole relative to the frame 13. Among them, the inside of the frame 13 is the internal space of the electronic device 100, and the internal space can also accommodate internal devices such as a SIM card, a memory card, a speaker and a receiver of the electronic device 100. The outside of the frame 13 is the external space of the electronic device 100.

[0043] The screen 11 is located on one side of the frame 13. The screen 11 includes a display surface (not shown) away from the frame 13, and the display surface is used to display images and videos. It should be understood that the screen 11 is not limited to Figure 1 and Figure 2 The 2D (Dimensions) display screen shown may also be a 2.5D curved screen or a 3D curved screen.

[0044] The screen 11 includes a cover plate and a display panel fixed on the cover plate. Among them, the cover plate can be made of transparent materials such as glass. The display panel can use LCD (Liquid Crystal Display, liquid crystal display), OLED (Organic Light-Emitting Diode, organic light-emitting diode) display screen, AMOLED (Active-Matrix Organic Light-Emitting Diode, active matrix organic light-emitting diode or active matrix organic light-emitting diode) display screen, FLED (Flex Light-Emitting Diode, flexible light-emitting diode) display screen, Mini LED, Micro LED, MicroOLED, QLED (Quantum Dot Light Emitting Diodes, quantum dot light-emitting diode), etc. In addition, the display panel can also be integrated with a touch function, that is, the display panel is a touch display panel. At this time, the display panel is electrically connected to the processor 30. The display panel can generate a touch signal and transmit the touch signal to the processor 30. The processor 30 receives the touch signal and controls the opening of the application software (Application, App) in the electronic device 100 according to the touch signal.

[0045] See also Figure 2 and Figure 3 , Figure 3 yes Figure 2 The structure diagram of the housing 12 in the electronic device 100 is shown. Figure 3 The rear cover 14 is not shown.

[0046] The housing 12 is located on the side of the screen 11 away from the display surface. The back cover 14 and the screen 11 are located on both sides of the frame 13, and together with the frame 13, they form the internal space of the electronic device 100. When the user uses the electronic device 100, the screen 11 is placed toward the user, and the back cover 14 is placed away from the user. Figure 1 It can be seen that the screen 11, the back cover 14 and the frame 13 are combined to form a roughly rectangular structure.

[0047] Specifically, the frame 13 includes a top surface and a bottom surface that are arranged opposite to each other, and an inner surface and an outer surface that are connected between the top surface and the bottom surface, and the inner surface is arranged opposite to the outer surface. The screen 11 is located on one side of the frame 13 close to the top surface of the frame 13, and the bottom surface of the frame 13 is connected to the periphery of the back cover 14. The opening of the through hole 130 is located on the outer surface of the frame 13. The through hole 130 extends from the outer surface of the frame 13 to the inner surface and passes through the outer surface of the frame 13. The shape of the through hole 130 is not limited to Figure 3The square shape shown may also be a circle or a bar. It should be noted that the directional terms such as "top" and "bottom" used in the electronic device 100 of the present application are mainly based on the electronic device 100 being attached. Figure 1 The display orientation in the figure is used to illustrate, and does not constitute a limitation on the orientation of the electronic device 100 in an actual application scenario.

[0048] In one embodiment, the frame 13 includes an upper frame 131 and a lower frame 132 that are relatively arranged, and a left frame 133 and a right frame 134 that are connected between the upper frame 131 and the lower frame 132, and the left frame 133 and the right frame 134 are relatively arranged. When the user uses the electronic device 100, the upper frame 131 is generally facing upward, the lower frame 132 is generally facing downward, the left frame 133 is close to the right hand side of the user, and the right frame 134 is close to the left hand side of the user. The through hole 130 is provided in the middle of the upper frame 131. When the functional device 60 extends out of the frame 13 from the through hole 130, it is located in the middle area of ​​the electronic device 100. The user can directly use the functional device 60 without adjusting the angle of the electronic device 100, thereby improving the user's experience.

[0049] The back cover 14 is mounted on the bottom surface of the frame 13. The back cover 14 can be mounted on the bottom surface of the frame 13 in a detachable manner to facilitate the repair and replacement of components such as memory cards, SIM cards and speakers in the electronic device 100. At this time, the frame 13 can be made of metal alloy materials such as titanium alloy or aluminum-magnesium alloy, and the back cover 14 can be made of engineering plastics such as PC (polycarbonate), ABS (acrylonitrile butadiene styrene copolymers) or metal alloys such as titanium alloy, aluminum-magnesium alloy. Alternatively, the back cover 14 and the frame 13 can be integrally formed to improve the structural stability of the electronic device 100. At this time, the frame 13 and the back cover 14 can be made of metal materials.

[0050] The middle plate 15 is located inside the frame 13 and is fixedly connected to the frame 13. Specifically, the middle plate 15 carries the screen 11 to provide support for the screen 11 to prevent the screen 11 from collapsing. Among them, the middle plate 15 is a plate-like structure. The middle plate 15 can be formed on the frame 13 by an injection molding process, so as to form a middle frame of an integrated structure with the frame 13. At this time, the material of the middle plate 15 can be supported by metal alloy materials such as titanium alloy or aluminum-magnesium alloy, and the middle plate 15 and the frame 13 are a whole, which is beneficial to improve the overall strength of the shell 12. It should be understood that the middle plate 15 can also be two independent components with the frame 13, and the present application does not make specific limitations on this.

[0051] See also Figure 2 and Figure 4 , Figure 4 yes Figure 2 The schematic diagram of the assembly structure of the circuit board 20, the processor 30 and the first connector 70 in the electronic device 100 is shown.

[0052] The circuit board 20 is located inside the frame 13 and fixed to the middle plate 15. Specifically, it is detachably mounted on the middle plate 15 to facilitate the maintenance and replacement of the circuit board 20. In this embodiment, the circuit board 20 includes a first circuit board 21 and a second circuit board 22 connected to the first circuit board 21. The first circuit board 21 and the second circuit board 22 together enclose an installation space 201, and the installation space 201 is used to install the driving mechanism 40, the support member 50 and the functional device 60, so as to reduce the thickness of the assembly structure of the driving mechanism 40, the support member 50, the functional device 60 and the circuit board 20 in the electronic device 100, which is conducive to the lightweight design of the electronic device 100. Among them, the first circuit board 21 is electrically connected to the second circuit board 22. It should be understood that the circuit board 20 can be the main board of the electronic device 100, and the circuit board 20 can also be other circuit boards in the electronic device 100 except the main board.

[0053] In one embodiment, the first circuit board 21 and the second circuit board 22 are both rigid circuit boards. The first circuit board 21 and the second circuit board 22 are integrally formed to form the circuit board 20, so as to simplify the molding process of the circuit board 20 and improve the overall strength of the circuit board 20. It should be understood that the first circuit board 21 and the second circuit board 22 can also be independent circuit boards, and are electrically connected through electrical connectors such as plug-ins.

[0054] The circuit board 20 includes a top surface and a bottom surface that are arranged opposite to each other, and a peripheral surface connected between the top surface and the bottom surface. The top surface of the circuit board 20 is partially recessed to form an installation space 201. The installation space 201 is recessed from the top surface of the circuit board 20 to the bottom surface, and penetrates the bottom surface and the peripheral surface of the circuit board 20. Specifically, the installation space 201 includes a first space 202, a second space 203 and a third space 204. The first space 202 is located in the edge area of ​​the circuit board 20 and extends along the Y direction, and is used to install the drive mechanism 40. The second space 203 is connected between the first space 202 and the third space 204, and extends along the X direction. The third space 204 extends along the Y-axis direction and is connected to the outside of the circuit board 20. Among them, the third space 204 and the second space 203 together form a space that is roughly "L" shaped, which is used to accommodate the support member 50 and the functional device 60.

[0055] The processor 30 is fixed to the circuit board 20 and electrically connected to the circuit board 20. Specifically, the processor 30 is fixed to the first circuit board 21 of the circuit board 20 and is electrically connected to the wiring of the first circuit board 21 embedded in the circuit board 20. The processor 30 may include one or more processing units. The multiple processing units may be, for example, an application processor (AP), a modem processor, a graphics processor (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural network processor (NPU). Among them, different processing units may be independent devices or integrated in one or more processors. It should be reasonable to be other processors of the electronic device 100.

[0056] The first connector 70 is electrically connected to the processor. Specifically, the first connector 70 is fixed to the circuit board 20 and electrically connected to the circuit board 20. The first connector 70 is fixed to the second circuit board 22 of the circuit board 20 and electrically connected to the wiring embedded in the second circuit board 22. That is, the first connector 70 is electrically connected to the processor 30 through the wiring embedded in the first circuit board 21 and the second circuit board 22.

[0057] The first connector 70 includes a first protective shell and a connection body fixed inside the first protective shell. The first protective shell is fixed to a position of the circuit board 20 close to the first space 202. The first protective shell is a tubular structure. The connection body is partially inserted into the first protective shell and fixed to the first protective shell, that is, the first protective shell is covered on the outer surface of the connection body to protect the connection body. Among them, the connection body is electrically connected to the processor 30. In this embodiment, the first connector 70 is a Type-C interface connector. Of course, in other embodiments, the first connector 70 may also be a Type-A interface connector or a Type-B interface connector.

[0058] In addition, the first protective shell can be made of metal materials such as stainless steel, which can not only play an electromagnetic shielding role to prevent the influence of external structures on the signals transmitted in the connection body, but also enhance the assembly stability between the first protective shell and the circuit board 20, and improve the reliability of the electronic device 100. The first protective shell can be fixed to the circuit board 20 by screws, welding or bonding.

[0059] The connecting body includes a tongue plate and a plurality of signal terminals arranged on the tongue plate. The tongue plate includes a top surface and a bottom surface arranged opposite to each other. The tongue plate is made of an insulating material to support and protect the plurality of signal terminals arranged thereon. The plurality of signal terminals are arranged on the top surface and the bottom surface of the tongue plate and are electrically connected to the processor 30. Specifically, the plurality of signal terminals arranged on the same surface of the tongue plate are spaced and arranged in parallel, that is, there are gaps between adjacent signal terminals to avoid interference between signals transmitted by adjacent signal terminals. The plurality of signal terminals are electrically connected to the processor 30.

[0060] In another embodiment, the difference from the above embodiment is that the first circuit board 21 is a rigid circuit board, and the second circuit board 22 is a flexible circuit board. At this time, the second circuit board 22 is fixed to the middle plate 15, the first connector 70 is fixed to one end of the second circuit board 22, and the other end of the second circuit board 22 is electrically connected to the first circuit board 21 to achieve the electrical connection between the first connector 70 and the first circuit board 21, and then to achieve the electrical connection with the processor 30. Since the second circuit board 22 is a flexible circuit board, the heterogeneous design of the circuit board 20 is avoided, the molding process of the circuit board 20 is simplified, and the space occupied by the circuit board 20 inside the frame 130 can also be simplified, which is conducive to improving the space utilization inside the frame 13.

[0061] See also Figure 2 and Figure 5 . Figure 5 yes Figure 2 A schematic structural diagram of the driving mechanism 40 in the electronic device 100 is shown.

[0062] The driving mechanism 40 is located inside the frame 13, fixed to the middle plate 15, and electrically connected to the circuit board 20. Specifically, the driving mechanism 40 is installed in the installation space (not marked in the figure) of the circuit board 20, and is used to drive the support member 50 to move so that the functional device 60 extends or retracts from the through hole (not marked in the figure) relative to the frame 13. Among them, the driving mechanism 40 is electrically connected to the processor 30 through the contact connected to the wiring embedded in the circuit board 20. It should be noted that in other embodiments, the driving mechanism 40 can also be fixed to the frame 13 or to the circuit board 20, and this application does not make specific limitations on this.

[0063] The driving mechanism 40 includes a base 41, a driving motor 42, a flexible circuit board 43, a screw (not shown) and a slider 44. The base 41 is installed in the first space of the installation space and can be fixed to the middle plate 15 in a detachable manner such as screws or bolts. The driving motor 42 and the screw are both installed on the base 41. The driving motor 42 is electrically connected to the circuit board 20 through the flexible circuit board 43, that is, the flexible circuit board 43 is electrically connected between the driving motor 42 and the processor 30. The screw extends along the Y direction and is rotationally connected to the driving motor 42. The slider 44 is sleeved on the screw and cooperates with the screw thread. The driving motor 42 receives the driving signal sent by the processor 30 through the flexible circuit board 43, drives the screw to rotate according to the driving signal, and then drives the slider 44 to move along the extension direction of the screw.

[0064] See also Figure 2 and Figure 6 , Figure 6 yes Figure 2 The schematic diagram of the assembly structure of the support member 50 and the driving mechanism 40 in the electronic device 100 is shown.

[0065] The support member 50 is fixed to the driving mechanism 40. Specifically, the support member 50 includes a first portion 51 and a second portion 52 connected to the edge of the first portion 51, and the first portion 51 is fixedly connected to the driving mechanism 40. The first portion 51 can be fixedly connected to the slider 44 of the driving mechanism 40 by a detachable manner such as screws or bolts, so as to facilitate the replacement and maintenance of the support member 50.

[0066] In this embodiment, the support member 50 is a rigid circuit board, which not only ensures the stability of the fixed connection between the support member 50 and the driving mechanism 40, but also effectively supports the functional device 60 and the second connector 80 fixed to the support member 50. It should be understood that in other embodiments, the support member 50 can also be a structural member with a supporting function such as a support frame.

[0067] The support member 50 and the driving mechanism 40 are installed in the installation space together. Specifically, the support member 50 is installed in the second space and the third space. The first part 51 of the support member 51 is accommodated in the second space, and the second part 52 is accommodated in the third space. The support member 50 is an "L"-shaped plate structure adapted to the second space and the third space.

[0068] Since the first portion 51 of the support member 50 is fixedly connected to the slider 44 of the driving mechanism 40, the support member 50 can move along the Y direction in the second space and the third space driven by the slider 44. In addition, since the driving mechanism 40 is installed in the first space, the driving mechanism 40 also limits the movement displacement of the support member 50 along the X direction and the Z direction, realizes the position limitation of the support member 50 in the X-axis direction and the Z-axis direction, and ensures the assembly stability of the support member 50 inside the frame 13.

[0069] See also Figure 2 and Figure 7 , Figure 7 yes Figure 2 The functional device 60 and the second connector 80 in the electronic device 100 are connected to Figure 6 Schematic diagram of the assembly structure of the structure shown.

[0070] The functional device 60 is fixed to the support member 50 and electrically connected to the support member 50. Specifically, the functional device 60 is fixed to the second part 52 of the support member 50 and is electrically connected to the wiring embedded in the second part 52 of the support member 50. Among them, the functional device and the support member 50 are installed together in the installation area (not marked in the figure). When the driving mechanism 40 drives the support member 50 to move, the functional device 60 extends or retracts from the through hole (not marked in the figure) relative to the frame 13. In this embodiment, the functional device 60 is a camera module. Among them, the camera module can be used for taking pictures, and can also be used for physiological feature recognition such as pupil recognition or facial recognition. It can be understood that the functional device 60 can also be a fingerprint recognition module.

[0071] It should be noted that the functional device 60 described in the present application extending from the through hole relative to the frame 13 means that the functional device 60 extends from the through hole to the inside of the frame 13, that is, the functional device 60 extends from the through hole from the inside of the frame 13 to the outside of the frame 13. The functional device 60 retracts from the through hole relative to the frame 13 means that the functional device 60 retracts from the through hole to the inside of the frame 13, that is, the functional device 60 retracts from the through hole from the outside of the frame 13 to the inside of the frame 13.

[0072] In one embodiment, when the functional device 60 is retracted relative to the frame 13, the support member 50 and the first circuit board 21 are arranged side by side in the thickness direction of the electronic device 100, that is, in the Z direction shown in the figure, that is, the support member 50 is accommodated in the installation space of the circuit board 20, and will not be stacked with the first circuit board 21, which not only avoids the movement of the support member 50 in the installation space to affect the electronic components on the first circuit board 21, improves the reliability of the electronic device 100 when in use, but also simplifies the assembly structure of the support member 50 and the first circuit board 21. It should be understood that in other embodiments, when the functional device 60 is retracted relative to the frame 13, the support member 50 and the first circuit board 21 are partially overlapped in the thickness direction of the electronic device 100. At this time, the volume of the first circuit board 21 is not limited, and the volume of the first circuit board 21 can be adaptively increased, so that more electronic components can be arranged on the first circuit board 21, thereby improving the integration of the electronic device 100. Moreover, the area where the first circuit board 21 overlaps with the support member 50 can still be arranged with wiring for electrically connecting components in pairs, and each position of the first circuit board 21 can be fully utilized.

[0073] The electronic device 100 further includes a fixed shell 110. The fixed shell 110 is fixed to the second portion 52 of the support member 50, and the functional device 60 is installed inside the fixed shell 110, so as to confine the functional device 60 inside the fixed shell 110, prevent the functional device 60 from falling off from the fixed shell 110, and improve the assembly stability of the functional device 60. The fixed shell 110 can be fixed to the top surface of the second portion 52, or the second portion 52 can also extend into the interior of the fixed shell 110 and be fixedly connected to the fixed shell 50, which is not specifically limited in the present application.

[0074] The fixed shell 110 is slidably connected to the frame 13, that is, the fixed shell 110 can extend or retract from the through hole relative to the frame 13. In other words, when the driving mechanism 40 drives the support member 50 to move, the fixed shell 110 and the functional device 60 both extend or retract from the through hole relative to the frame 13, so that the fixed shell 110 always protects the functional device 60. Among them, the outer surface of the fixed shell 110 is covered with a sealing member. When the fixed shell 110 is retracted relative to the frame 13, the sealing member is clamped between the fixed shell 110 and the frame 13 to prevent water vapor or other impurities outside the frame 13 from entering the inside of the frame 13, thereby improving the sealing performance of the electronic device 100.

[0075] The second connector 80 is electrically connected to the functional device 60. Specifically, the second connector 80 is fixed to the support member 50 and electrically connected to the support member 50. Among them, the second connector 80 is fixed to the first part 51 of the support member 50 and electrically connected to the wiring embedded in the first part 51 of the support member 50. That is, the second connector 80 is electrically connected to the functional device 60 through the wiring embedded in the first part 51 and the second part 52, so that the functional device 60 and the second connector 80 do not need to be electrically connected through external wiring, which not only avoids the wiring problem of external wiring, but also improves the neatness of the inside of the frame 13.

[0076] At this time, the second connector 80 is located between the functional device 60 and the driving mechanism 40. Compared with the functional device 60, the second connector 80 is closer to the driving mechanism 40. When the driving mechanism 60 drives the support member 50 to move, the second connector 80 will not shake, and the movement trajectory of the second connector 80 is more accurately controllable, ensuring the accurate contact connection between the second connector 80 and the first connector 70.

[0077] See also Figure 2 and Figure 8 , Figure 8 yes Figure 7 The structure shown is Figure 4 Schematic diagram of the assembly structure of the structure shown.

[0078] The second connector 80 and the support member 50 are installed together in the installation area (not marked in the figure) of the circuit board 20. The direction in which the second connector 80 moves toward the first connector 70 is the same as the direction and distance in which the functional device 60 moves relative to the frame 13 when it is extended, and the direction in which the second connector 80 moves away from the first connector 70 is the same as the direction and distance in which the functional device 60 moves relative to the frame 13 when it is retracted, so that when the driving mechanism 40 drives the support member 50 to move, so as to drive the functional device 60 to move relative to the frame 13, the second connector 80 is driven to move relative to the first connector 70, ensuring that when the functional device 60 is extended relative to the frame 13, the second connector 80 is connected to the first connector 70, and when the functional device 60 is retracted relative to the frame 13, the second connector 80 is disconnected from the first connector 70.

[0079] Please also read Figure 9a and Figure 9b . Figure 9a yes Figure 2 A schematic structural diagram of a second connector 80 in an electronic device 100 is shown. Figure 9b yes Figure 9a The partial cross-sectional structure schematic diagram of the second connector 80 cut along the AA direction is shown. In the drawings of the present application, "cut along the AA direction" means cutting along the AA line and the plane where the arrows at both ends of the AA line are located.

[0080] Specifically, the second connector 80 is adapted to the first connector 70. The second connector 80 includes a second protective shell 81 and a plurality of spring pieces 82 housed in the second protective shell 81, and the plurality of spring pieces 82 are electrically connected to the functional device 60. When the functional device 60 is extended relative to the frame 13, the tongue of the first connector 70 extends into the second protective shell 81 of the second connector 80, and the spring piece 82 of the second connector 80 contacts the signal terminal of the first connector 70, thereby realizing the connection between the second connector 80 and the first connector 70, that is, realizing the electrical connection between the functional device 80 and the processor 30. When the functional device 60 is retracted relative to the frame 13, the spring piece 82 of the second connector 80 is away from the signal terminal of the first connector 70, and the tongue of the first connector 70 is detached from the second protective shell 81 of the second connector 80, thereby realizing the disconnection between the second connector 80 and the first connector 70, that is, realizing the disconnection between the functional device 80 and the processor 30.

[0081] See also Figure 2 and Fig.10 , Fig.10 yes Figure 2 The electronic device 100 is shown as a schematic diagram of a structure in another state. Fig.10 The rear cover 14 is not shown.

[0082] When the electronic device 100 needs to use the functional device 60, the processor 30 sends a control signal to the driving mechanism 40, and the slider 44 of the driving mechanism 40 drives the support member 50 to slide upward along the positive direction Y in the installation space until the functional device 60 extends out from the through hole relative to the frame 13. At this time, the second connector 80 and the first connector 70 are plugged in to achieve electrical connection. Since the first connector 70 is electrically connected to the processor 30, the processor 30 can realize signal control of the functional device 60.

[0083] When the electronic device 100 does not need to use the functional device 60, the processor 30 stops communicating with the functional device 60 and sends a control signal to the drive mechanism 40. The slider 44 of the drive mechanism 40 drives the support member 50 to slide along the negative direction Y in the installation space until the functional device 60 retracts from the through hole relative to the frame 13. At this time, the second connector 80 is disconnected from the first connector 70 to cut off the power.

[0084] In the electronic device 100 shown in the embodiment of the present application, the functional device 60 is installed on the support member 50. The functional device 60 only needs to be powered on and off with the processor 30 through the second connector 80. There is no special requirement for the length of the FPC that realizes the electrical connection in the functional device 60. There is no need to design FPCs of different lengths for different electronic devices 100. The functional device 60 can be used in a standardized manner with other functional devices that do not require lifting design, which saves the production cost of the electronic device 100 and improves the competitiveness of the electronic device 100. In addition, the FPC is not used to connect the functional device 60 and the processor 30, which also ensures that the movement trajectory of the functional device 60 is controllable, avoids the problem of the FPC being bent or the internal wiring of the FPC being fatigued and fractured during the lifting process of the functional device 60, and ensures the reliability of the functional device 60 during use.

[0086] The electronic device 100 shown in this embodiment is different from the electronic device 100 shown in the above embodiment in that the third space 204 of the installation space 201 and the second space 203 together form a space that is roughly in the shape of an inverted "T". The first connector 70 is fixed to a position of the circuit board 20 away from the first space 202. That is, the first connector 70 is located on a side of the third space 204 away from the first space 202.

[0087] See also Fig.12 and Fig.13 . Fig.12It is a schematic diagram of the assembly structure of the driving mechanism 40, the supporting member 50, the functional device 60 and the second connector 80 in the second electronic device 100 provided in an embodiment of the present application. Fig.13 yes Fig.12 The structure shown is Fig.11 Schematic diagram of the assembly structure of the structure shown.

[0088] The support member 50 includes a first portion 51 and a second portion 52 connected to the edge of the first portion 51. The support member 50 is an inverted "T"-shaped plate structure adapted to the second space and the third space. Specifically, the first portion 51 is fixedly connected to the driving mechanism 40, the second connector 80 is fixed to the first portion 51 and is spaced apart from the driving mechanism 40, the second portion 52 is located between the second connector 80 and the driving mechanism 40, and the functional device 60 is fixed to the second portion 52.
