electronic devices

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on March 30, 2023, with application number 202320751180.1 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 field of electronic technology, and in particular to an electronic device. Background Art

[0003] With the development of technology, people have higher and higher requirements for the performance of electronic devices such as mobile phones, such as thinness and high power.

[0004] Taking a foldable screen mobile phone as an example, the electronic device may include a first middle frame, a second middle frame and a flexible display screen. The first middle frame and the second middle frame are rotatably connected, and the flexible display screen is covered on the same side of the first and second middle frames. A plug-in interface is provided on the border of the first middle frame. The interface components in the electronic device are accommodated in the first middle frame and pass through the plug-in interface to electrically connect the electronic device to an external device. In order to improve the performance of electronic devices such as lightness and high power consumption, the related art moves the driver board of the flexible display screen from the second middle frame to the first middle frame. This will result in the electronic components on the driver board being unable to be accommodated in the first middle frame.

[0005] How to accommodate the electronic components on the driver board in the first middle frame while meeting the requirements of lightweight and thin electronic equipment has become a technical problem to be solved.

[0006] Utility Model Content

[0007] The present application provides an electronic device that can accommodate electronic components on a driving board within a first middle frame while meeting the requirements of thinness and lightness of the electronic device.

[0008] According to a first aspect of an embodiment of the present application, an electronic device is provided. The electronic device includes a circuit board, an interface device, a housing, and a first display screen. The housing includes a first middle frame and a second middle frame that are rotatably connected. The first display screen is covered on the same side of the first middle frame and the second middle frame. The first middle frame has a receiving cavity and a plug interface that are interconnected. The circuit board is located in the receiving cavity. The interface device is disposed in the plug interface and is electrically connected to a side of the circuit board facing away from the first display screen. The interface device is configured to be electrically connected to an external device.

[0009] The first display screen has a driving board on a side facing the first middle frame. The driving board has an electronic component group including at least one electronic component. The first middle frame has an accommodating cavity at a position corresponding to the electronic component group. The electronic component group is located in the accommodating cavity.

[0010] In the embodiment of the present application, the interface device is arranged to be inserted into the plug interface, so that the electronic device can be electrically connected and conducted with the external device through the interface device. On this basis, since the interface device and the side of the circuit board facing away from the first display screen are electrically connected, the distance between the interface device and the first display screen can be increased to facilitate the formation of the accommodating cavity on the first middle frame, so that the electronic device group on the driver board can be located in the accommodating cavity and assembled in the first middle frame at the same time as the interface device. In this way, while ensuring that the first display screen can be assembled on the first and second middle frames, since the driver board is located on the side of the first display screen facing the first middle frame, it can also meet people's requirements for lightweight and high power consumption of foldable electronic devices.

[0011] In some optional embodiments, the side of the circuit board facing away from the first display screen is the component side of the circuit board, and the component side has at least one component protruding from the component side, and the component is arranged around the peripheral side of the interface device.

[0012] In this way, the interface device can reuse the space occupied by the components in the first middle frame in the thickness direction of the electronic device, so as to facilitate the lightweight and thin design of the electronic device.

[0013] In some optional embodiments, the height of the interface device on the component surface is equal to or less than the maximum height of the component on the component surface, so as to avoid the interface device being disposed on the component surface affecting the thickness of the electronic device.

[0014] In some optional embodiments, the component includes at least one of an electronic component and a fixed component, so that the interface device can reuse the space occupied by at least one of the electronic component and the fixed component in the first middle frame in the thickness direction of the electronic device.

[0015] In some optional embodiments, the fixing element includes at least one of a spring and a fastener, so that the interface device can reuse the space occupied by at least one of the spring and the fastener in the first middle frame in the thickness direction of the electronic device.

[0016] In some optional embodiments, the first middle frame includes a middle plate and a frame. The frame is arranged around the periphery of the middle plate and forms a receiving cavity with the middle plate. The plug interface is located on the frame. The receiving cavity is a recessed area of ​​the middle plate toward the side of the circuit board, so that a receiving cavity can be formed on the middle plate without affecting the structural strength of the first middle frame, so as to facilitate the assembly of the drive board in the first middle frame.

[0017] In some optional embodiments, the middle plate is bent toward one side of the circuit board at a position corresponding to the electronic component group to form a receiving cavity. The middle plate is supported on the circuit board so that the electronic component group can be assembled in the receiving cavity while the middle plate can also be supported on the circuit board to fix the circuit board in the receiving cavity.

[0018] In some optional embodiments, the middle plate has two bent portions and a horizontal support portion for supporting the circuit board, the two bent portions being arranged on opposite sides of the electronic component group along the axial direction of the plug-in interface and both bent toward one side of the circuit board;

[0019] The horizontal supporting portion is connected between the two bending portions and forms an accommodating cavity with the two bending portions.

[0020] In this way, the middle plate can effectively utilize the distance between the interface device and the first display screen, form a accommodating cavity through its own local bending, and realize the assembly of the electronic device group and the driving board in the first middle frame. At the same time, the middle plate can also be stably supported on the circuit board through the horizontal support part.

[0021] In some optional embodiments, the accommodating cavity matches the outer edge contour of the electronic device group, so as to ensure that the electronic device group can be completely accommodated in the accommodating cavity while saving the space occupied by the electronic device group in the first middle frame, thereby further improving the space utilization in the electronic device.

[0022] In some optional embodiments, the interface device includes a device body having an electrical connection end and a plug end connected to the electrical connection end, the electrical connection end is electrically connected to a side of the circuit board facing the plug interface, and the plug end is arranged in the middle of the plug interface.

[0023] In this way, the interface device is electrically connected to the circuit board through the electrical connection end, and since the plug end is arranged through the middle of the plug interface, it can also ensure that the external device is smoothly plugged into the plug interface and the plug end.

[0024] In some optional embodiments, there is a penetration space between the circuit board and the plug interface, which is connected to the plug interface. The plug end is bent toward one side of the first display screen and passes through the penetration space and is inserted into the middle of the plug interface. The bending of the plug end ensures that the interface device can still be inserted into the middle of the plug interface when it is located on the component surface, thereby ensuring smooth connection of the external device between the plug interface and the plug end.

[0025] In some optional embodiments, an opening is provided on an edge of the circuit board facing the plug interface, and a through space is provided between the edge of the opening and the first middle frame;

[0026] The electrical connection end is overlapped on the circuit board, the plug end is clamped in the opening, and is bent in the penetration space toward one side of the first display screen.

[0027] In this way, while facilitating the electrical connection between the electrical connection end and the circuit board, the arrangement in which the plug-in end is clamped in the opening not only facilitates the electrical connection between the electrical connection end and the circuit board, but also enables the interface device to reuse a certain space with the circuit board in the thickness direction of the electronic device, so as to further reduce the height of the interface device on the circuit board.

[0028] In some optional embodiments, the interface device also includes a cover plate, which is arranged on the electrical connection end and is connected to the circuit board so that the cover plate is pressed on the electrical connection end, thereby enhancing the stability of the electrical connection between the electrical connection end and the circuit board, and can also cover the electrical connection end by the cover plate to protect the electrical connection end.

[0029] In some optional embodiments, the projections of the interface device and the electronic device group on the circuit board at least partially overlap, so as to save the space occupied by the electronic device group and the interface device in the length direction of the first middle frame and meet the large power requirements of the electronic device.

[0030] In some optional embodiments, one end of the interface device electrically connected to the circuit board has a first projection surface on the circuit board, and at least a portion of the electronic device group is located within the first projection surface, so that the projections of the electrical connection end and the electronic device group on the circuit board can at least partially overlap.

[0031] In some optional implementations, the first display screen is a flexible display screen, and the driving board is a driving circuit board.

[0032] By providing a flexible display screen, the shape of the first display screen can be changed accordingly when the configuration of the electronic device changes, thereby realizing the foldable and flattenable functions of the electronic device. In addition, since the driver board is a driver circuit board, it is convenient for the driver circuit board to drive the first display screen to realize the display function of the first display screen.

DETAILED DESCRIPTION

[0047] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0048] An embodiment of the present application provides an electronic device, which may include but is not limited to a mobile phone (such as a foldable screen mobile phone or a non-foldable screen mobile phone), a tablet computer (i.e., a pad), a virtual reality (VR) device, a smart wearable device, and other electronic devices with interface devices.

[0049] FIG1 shows a schematic structural diagram of an electronic device.

[0050] As shown in Figure 1, the electronic device 100 includes a shell. When the electronic device 100 is a non-folding electronic device (such as a non-folding screen mobile phone), the shell may include a first middle frame 1 and a back cover 3. The back cover 3 is connected to one side of the first middle frame 1 and provides a structural frame for the non-folding electronic device together with the first middle frame 1.

[0051] FIG. 2 illustrates an exploded view of the electronic device in FIG. 1 .

[0052] As shown in Figure 2, the first middle frame 1 includes a middle plate 12 and a frame 13. The frame 13 is arranged around the peripheral edge of the middle plate 12 and together with the middle plate 12, it constitutes the first middle frame 1. The frame 13 is a square ring structure composed of a top frame 131, a left frame 132, a bottom frame 133, and a right frame 134 connected end to end. As shown in Figure 2, in some embodiments, when the electronic device 100 has a display function (for example, the electronic device 100 is a mobile phone or a tablet computer), the electronic device 100 also includes a first display screen 4, which is covered on the first middle frame 1 to enable the first display screen 4 to be assembled on the first middle frame 1.

[0053] As shown in FIG2 , when the electronic device 100 is a non-foldable electronic device, the first display screen 4 can be a rigid display screen, which is provided on the side of the first middle frame 1 away from the back cover 3 and, together with the first middle frame 1 and the back cover 3, forms a housing space (not shown in the figure) for the electronic device 100. This housing space can be used to accommodate not only the circuit board 5 and battery (not shown in the figure) of the electronic device 100, but also functional components such as the interface device 6, the earpiece, the camera module 7, the speaker (not shown in the figure), and the microphone (not shown in the figure).

[0054] The circuit board 5 may include a main circuit board 5a (referred to as the main board) and a secondary circuit board 5b (referred to as the secondary board). The main circuit board 5a may be understood as a circuit board carrying electronic components such as a system on a chip (SoC), dynamic random access memory (DRAM), a power management unit, a flash memory chip, and a radio frequency chip. The secondary circuit board 5b may be understood as a circuit board carrying electronic components such as a microphone and a speaker.

[0055] The secondary circuit board 5b is typically disposed within the housing on a side facing the interface device 6, while the primary circuit board 5a is typically disposed within the housing on a side away from the interface device 6. The first display screen 4 can be electrically connected to the primary circuit board 5a to enable the first display screen 4 to perform display or operation functions. The camera module 7 can also be electrically connected to the primary circuit board 5a so that when a user inputs a capture command, the circuit board 5 can control the camera module 7 to capture an image, thereby enabling the capture function of the electronic device 100.

[0056] The interface device 6 can be a Universal Serial Bus (USB) interface. Currently, the Universal Serial Bus interface mainly includes a Micro USB interface and a Type-C interface. The bottom frame 133 has a plug interface 135 connected to the receiving space. The interface device 6 is accommodated in the receiving space and is passed through the middle of the plug interface 135. It can be electrically connected to an external power supply to charge the electronic device 100. Alternatively, the interface device 6 can also electrically connect the electronic device 100 to other external devices such as headphones and storage devices. The middle of the plug interface 135 can be understood as the middle area within the plug interface 135, rather than the upper area or lower area within the plug interface 135.

[0057] 3 to 5 respectively illustrate schematic structural diagrams of an electronic device in different configurations provided by an embodiment of the present application.

[0058] Referring to Figures 3 to 5, in some embodiments, when the electronic device 100 is a foldable electronic device, the shell may further include, in addition to the first middle frame 1 and the back cover 3, a second middle frame 2 rotatably connected to the first middle frame 1, and the first middle frame 1 and the second middle frame 2 are rotatably connected to both sides of the rotating assembly 8 so that the first middle frame 1 and the second middle frame 2 can rotate relative to each other, thereby changing the configuration of the electronic device 100.

[0059] Specifically, the electronic device 100 may further include a rotating assembly 8, and the first middle frame 1 and the second middle frame 2 are rotatably connected to both sides of the rotating assembly 8 to achieve relative rotation between the first middle frame 1 and the second middle frame 2. The rotating assembly 8 may be a shaft assembly, a hinge assembly, or other structural assembly capable of achieving rotation.

[0060] As shown in FIG3 , when the first middle frame 1 and the second middle frame 2 move toward each other in the direction of the arrow in FIG3 , the first middle frame 1 rotates relative to the second middle frame 2 and is stacked on the second middle frame 2. At this point, the first middle frame 1 and the second middle frame 2 are stacked on each other, and the electronic device 100 is in the folded state shown in FIG4 .

[0061] 3 , when the first middle frame 1 and the second middle frame 2 move away from each other in the direction opposite to the arrows in FIG3 , the first middle frame 1 rotates relative to the second middle frame 2 to the plane where the second middle frame 2 is located. At this time, the electronic device 100 is in the flattened state shown in FIG5 .

[0062] As shown in Figures 3 to 5, when the electronic device 100 is a foldable electronic device (such as a foldable screen mobile phone), the first display screen 4 can be a flexible display screen, wherein the first display screen 4 is located on the same side of the first middle frame 1 and the second middle frame 2, so as to realize the assembly of the first display screen 4 in the electronic device 100.

[0063] Furthermore, when the configuration of the electronic device 100 changes, the shape of the first display screen 4 also changes accordingly. For example, when the electronic device 100 is in a folded state, the first display screen 4 is also folded, and when the electronic device 100 is in an unfolded state, the first display screen 4 is also unfolded.

[0064] As shown in Figures 3 to 5, the first middle frame 1 and the second middle frame 2 can be oriented in the direction indicated by the arrows in Figure 3, so that when the electronic device 100 is in a folded state, the first display screen 4 can be bent and attached to the first middle frame 1 and the second middle frame 2 and located inside the electronic device 100 (as shown in Figure 4). In this case, the electronic device 100 can be an inner folding screen device.

[0065] Alternatively, in some embodiments, when the electronic device 100 moves from the flat state to the folded state, the first middle frame 1 and the second middle frame 2 are both moved toward the side away from the first display screen 4 to fold, so that when the electronic device 100 is in the folded state, the first display screen 4 can still be bent and attached to the first middle frame 1 and the second middle frame 2, but is completely exposed to the outside of the electronic device 100. In this case, the electronic device 100 can be an external folding screen device.

[0066] The first display screen 4 has a display surface and a non-display surface, which are located on opposite sides of the first display screen 4. The first display screen 4 has a driver board 41 on the non-display surface. Driver board 41 is a driver circuit board, which is generally a flexible circuit board. Driver components, resistors, capacitors, and other electronic components are arranged on the driver board 41. The area on the driver board 41 where these electronic components are arranged can be referred to as a device area. The first display screen 4 can be electrically connected to a circuit board 5 (e.g., a main circuit board 5a) via the driver circuit board to enable the display or operation functions of the first display screen 4.

[0067] The structure of the electronic device 100 of the present application is further explained below by taking an inward folding screen device as an example.

[0068] FIG6 is an exploded view of the electronic device in FIG5 .

[0069] As shown in Figure 6, in some embodiments, when the electronic device 100 is an inward folding screen device, the electronic device 100 may further include a second display screen 9, which may be a rigid display screen and is located on the side of the second middle frame 2 opposite to the first display screen 4. In this case, the back cover 3 may be located on the side of the first middle frame 1 opposite to the first display screen 4. When the electronic device 100 is in a flattened state, the flexible display screen may serve as the front of the electronic device 100, and the back cover 3 and the second display screen 9 may serve as the back of the electronic device 100. When the electronic device 100 is in a folded state, the back cover 3 may serve as the back of the electronic device 100, and the second display screen 9 may serve as the front of the electronic device 100.

[0070] As shown in Figure 6, the back cover 3 can be together with the first middle frame 1, the second middle frame 2, the first display screen 4 and the second display screen 9 to form a receiving space. Functional devices such as the circuit board 5, the camera module 7, the battery, the interface device 6, the speaker, the microphone, the earpiece, etc. can be accommodated in the receiving space. The plug interface 135 is generally provided on the bottom frame 133 of the first middle frame 1 (as shown in Figure 5). The interface device 6 is accommodated between the first middle frame 1 and the back cover 3, and is passed through the middle of the plug interface 135, and is electrically connected to the circuit board 5 (such as the auxiliary circuit board 5b) accommodated in the first middle frame 1. This is to electrically connect the electronic device 100 to external devices such as an external power supply, headphones, and storage devices.

[0071] At the same time, a battery is also contained in the first middle frame 1 to power the electronic components in the first middle frame 1. The placement of other components such as the battery, speaker, microphone, and earpiece in the electronic device 100 can be referred to the description in the existing related art and will not be further described here.

[0072] FIG. 7 is a schematic diagram illustrating the position change of a driving board of a flexible display screen provided in the related art within an electronic device.

[0073] Since thinness and high power consumption have always been the main contradictions of foldable electronic devices. As shown in Figure 7, in the related art, the electronic device 100a moves the driving board 41a of the first display screen 4a from the second middle frame 2a to the first middle frame 1a. Similar to the above-mentioned first middle frame 1, the first middle frame 1a is also a middle frame in the electronic device 100a that has an insertion port 135a and accommodates an interface device (not shown in the figure). Studies have shown that this can improve the space utilization rate in the electronic device 100a and increase the battery capacity, so as to meet people's requirements for thinness and high power consumption of foldable electronic devices (such as foldable screen mobile phones).

[0074] FIG8 is a schematic diagram showing the assembly of an interface device provided in the related art within an electronic device.

[0075] As shown in Figure 8, when the driving board (not shown in the figure) is provided in the first middle frame 1a, it will be located in the first middle frame 1a together with the interface device 6a and the circuit board 5c. The circuit board 5c can be understood as the above-mentioned auxiliary circuit board 5b. Since the interface device 6a (such as the Type-C interface) is usually soldered to the side of the circuit board 5c facing the first display screen 4a, this will result in a smaller gap between the interface device 6a and the non-display surface of the first display screen 4a. Since the available space in the first middle frame 1a is extremely limited, when the driving board and the interface device 6a are both located in the first middle frame 1a, without affecting the lightweight and thinness of the electronic device 100 (the thickness of the whole machine does not change too much), there will be no space in the first middle frame 1a to accommodate the electronic devices on the driving board. The electronic devices on the driving board are difficult to be assembled in the first middle frame 1a, affecting the assembly of the first display screen 4a on the first middle frame 1a and the second middle frame 2a.

[0076] Therefore, how to realize the assembly of the electronic components and interface components of the driving board in the first middle frame 1 while meeting the requirements of thinness and lightness of electronic equipment has become a technical problem to be solved.

[0077] In view of this, the electronic device 100 provided in the embodiment of the present application can increase the distance between the interface device 6 and the first display screen 4 by arranging the interface device 6 on the side of the circuit board 5 away from the first display screen 4, so that on the basis of meeting the lightness and thinness of the electronic device 100, the electronic devices on the driving board 41 and the interface device 6 can be accommodated in the first middle frame 1, so that the first display screen 4 can be smoothly assembled on the first middle frame 1 and the second middle frame 2.

[0078] The structure of the electronic device 100 of the present application will be further described below with reference to the accompanying drawings and embodiments.

[0079] FIG9 illustrates a first assembly diagram of an interface device provided in an electronic device according to an embodiment of the present application, and FIG10 illustrates a cross-sectional view of the electronic device in FIG9 taken along the AA direction.

[0080] As shown in Figures 9 and 10, electronic device 100 includes a circuit board 5, an interface device 6, a housing, and a first display screen 4. The housing includes a first middle frame 1 and a second middle frame (not shown) that are rotatably connected. The first display screen 4 is located on the same side of the first and second middle frames. The first middle frame 1 has a receiving cavity 11 and an insertion port 135 that communicate with each other. The circuit board 5 is located within the receiving cavity 11. The interface device 6 is disposed within the insertion port 135 and is electrically connected to the side of the circuit board 5 facing away from the first display screen 4. The interface device 6 is configured to electrically connect to an external device.

[0081] In this way, the interface device 6 can be plugged into the plug port 135, so that when the electronic device 100 is assembled in the first middle frame 1, when the external device is plugged into the interface device 6 at the plug port 135, the interface device 6 can realize electrical connection and conduction between the electronic device 100 and the external device.

[0082] The circuit board 5 of the present application may be the aforementioned auxiliary circuit board 5 b, so that the interface device 6 is electrically connected to the auxiliary circuit board 5 b to connect the electronic device 100 with the external device.

[0083] It should be noted that the rotational connection between the first middle frame 1 and the second middle frame can refer to the relevant description above and will not be further elaborated here.

[0084] As shown in FIG10 , the first display screen 4 has a driving board 41 on the side facing the first middle frame 1. The driving board 41 has an electronic component assembly 411 including at least one electronic component. The first middle frame 1 has a receiving cavity 121 on the side facing the first display screen 4. The electronic component assembly 411 is located within the receiving cavity 121.

[0085] The space enclosed by the first display screen 4, the first middle frame 1 and the back cover 3 for accommodating electronic devices all belongs to the accommodation space of the electronic device 100 on one side of the first middle frame 1. In other words, the accommodation space may include but is not limited to the accommodation cavity 121 and the accommodation cavity 11.

[0086] Compared with the existing setting in which the interface device 6a is located on the side of the circuit board 5c facing the first display screen 4a, the present application electrically connects the interface device 6 to the side of the circuit board 5 facing away from the first display screen 4, which can increase the distance between the interface device 6 and the first display screen 4, so as to facilitate the formation of the accommodating cavity 121 on the first middle frame 1, so that the electronic device group 411 can be located in the accommodating cavity 121 and assembled in the first middle frame 1 at the same time as the interface device 6, thereby realizing the assembly of the driving board 41 in the first middle frame 1.

[0087] Since the first middle frame 1 is a middle frame in the electronic device 100 that has a plug-in port 135 and accommodates an interface device (not shown in the figure), and the driving board 41 is located inside the first middle frame 1, the first display screen 4 can not only be assembled on the first middle frame 1 and the second middle frame 2, but also meet people's requirements for lightweight and thin foldable electronic devices as well as high power consumption.

[0088] Therefore, the present application electrically connects the interface device 6 to the side of the circuit board 5 facing away from the first display screen 4, and on the basis of meeting the requirements of lightness and thinness of the electronic device, it can realize the assembly of the electronic device group 411, the driving board 41 and the interface device 6 in the first middle frame 1.

[0089] The first display screen 4 may be a flexible display screen, so that when the configuration of the electronic device 100 changes, the shape of the first display screen 4 can also change accordingly, thereby realizing the folding and unfolding functions of the electronic device 100. It should be noted that when the configuration of the electronic device 100 changes, the change in the shape of the first display screen 4 can be referred to the relevant description above, and no further details are given here.

[0090] The driver board 41 may be a driver circuit board that drives the first display screen 4 to implement the display function of the first display screen 4. The electronic component group 411 may include multiple electronic components (not separately illustrated in the figure), which may include but are not limited to the driver components, resistors, capacitors, etc. The structure of the driver board 41 can be found in the description of the related art and will not be further described here.

[0091] It should be noted that when the electronic device 100 is a non-folding electronic device (such as a non-folding screen mobile phone), a driving board 41 is also provided on the first display screen 4 (rigid display screen), and the interface device 6 and the driving board 41 can also be arranged in the first middle frame 1 of the non-folding electronic device with reference to the layout shown in Figure 10.

[0092] The structure of the electronic device 100 of the present application is further described below by taking the electronic device 100 as a foldable electronic device as an example.

[0093] Because the Type-C interface has the characteristic of blind plugging (adoption) with external devices compared to the Micro USB interface, there is no restriction on the plugging direction of the external device on the Type-C interface when connecting to the external device, making the Type-C interface widely used in electronic devices. Therefore, the interface device 6 in this application mainly refers to the Type-C interface.

[0094] The structure of the electronic device 100 of the present application is further described below using the Type-C interface as an example.

[0095] The interface device 6 has a plug end 612 for plugging into an external device, and the shape of the plug port 135 matches the shape of the plug end 612. Taking the Type-C interface as an example, the outer edge contour of the plug end 612 of the interface device 6 can be an oblong shape, as shown in Figure 9, and the shape of the plug port 135 can be an oblong opening that matches the shape of the plug end 612 of the interface device 6.

[0096] The interface device 6 can be electrically connected to the circuit board 5 by welding or other methods. In this application, the connection method between the interface device 6 and the circuit board 5 is not further limited.

[0097] As shown in FIG10 , the side of the circuit board 5 facing away from the first display screen 4 is the component surface 52 of the circuit board 5 . Component surface 52 has at least one component 51 protruding from the component surface 52 . Component 51 is disposed around the periphery of the interface device 6 , so that the interface device 6 can reuse the space occupied by component 51 within the first middle frame 1 in the thickness direction of the electronic device 100 . This reduces or even avoids the impact of the interface device 6 being disposed on the component surface 52 on the thickness of the electronic device 100 . While meeting the lightweight design of the electronic device 100 , the arrangement of at least one component 51 around the periphery of the interface device 6 also meets the layout requirements of the component 51 on the circuit board 5 . The thickness direction of the electronic device 100 can be seen in the Z direction in FIG9 .

[0098] It should be noted that when the interface device 6 is electrically connected to the component surface 52, the setting positions of at least some of the components on the circuit board 5 on the component surface 52 need to be rearranged so that at least some of the components 51 are arranged around the interface device 6 to ensure that the interface device 6 can be electrically connected to the component surface 52 and passed through the plug interface 135.

[0099] Among them, the component 51 may include at least one of an electronic component and a fixed component, so that the interface device 6 can reuse the space occupied by at least one of the electronic component and the fixed component in the first middle frame 1 in the thickness direction of the electronic device 100, so as to reduce or even avoid the impact of the interface device 6 on the thickness of the electronic device 100 when it is set on the component surface 52.

[0100] The electronic components may be board-to-board (BTB) connectors 511 , coaxial cables 512 , or other electronic devices on the circuit board 5 .

[0101] The fixing element includes at least one of a spring 513 and a fastener. The fastener may include, but is not limited to, a screw or bolt on the circuit board 5. This allows the interface device 6 to reuse the space occupied by the electronic components, spring 513, or fastener within the first middle frame 1 in the thickness direction of the electronic device 100, thereby reducing or even preventing the thickness of the electronic device 100 from being affected by the interface device 6 being disposed on the component surface 52.

[0102] In some embodiments, when the height of the interface device 6 on the component surface 52 is less than or equal to the maximum height of the component 51 on the component surface 52 (for example, the component 51 is a board-to-board connector 511 or a spring clip 513), the interface device 6 can completely reuse the space occupied by the board-to-board connector 511 or the spring clip 513 in the first middle frame 1 in the thickness direction of the electronic device 100 to avoid affecting the thickness of the electronic device 100 when the interface device 6 is set on the component surface 52, so as to meet the lightweight design of the electronic device 100.

[0103] As shown in Figure 10, in other embodiments, when the height of the interface device 6 on the component surface 52 is greater than the maximum height of the component 51 on the component surface 52 (for example, the component 51 is a board-to-board connector 511 or a spring clip 513), the interface device 6 can partially reuse the space occupied by the board-to-board connector 511 or the spring clip 513 in the first middle frame 1 in the thickness direction of the electronic device 100, so as to reduce the excessive impact on the thickness of the electronic device 100 when the interface device 6 is set on the component surface 52, and can also meet the lightweight and thin design of the electronic device 100.

[0104] As shown in Figure 10 , as described above, the first middle frame 1 includes a middle plate 12 and a frame 13 . The frame 13 surrounds the middle plate 12 and, together with the middle plate 12, forms a receiving cavity 11 . The insertion port 135 is located on the frame 13 . The structure of the frame 13 is described above and will not be further elaborated here. Specifically, the insertion port 135 may be provided on the bottom frame 133 of the frame 13 .

[0105] In some embodiments, the accommodating cavity 121 may be a recessed area on the side of the middle plate 12 facing the circuit board 5 (as shown in FIG10 ). In this way, the accommodating cavity 121 can be formed on the middle plate 12 without affecting the structural strength of the first middle frame 1 , thereby facilitating the assembly of the electronic component assembly 411 and the driver board 41 within the first middle frame 1 .

[0106] Specifically, the middle plate 12 is bent toward one side of the circuit board 5 at a position corresponding to the electronic device group 411 to form a receiving cavity 121. The middle plate 12 is supported by the circuit board 5 (as shown in FIG10 ). This bending of the middle plate 12 allows the formation of the receiving cavity 121 without affecting the structural strength of the first middle frame 1, thereby facilitating the assembly of the electronic device group 411 within the receiving cavity 121. Furthermore, the middle plate 12 can also support the circuit board 5, thereby securing the circuit board 5 within the receiving cavity 11.

[0107] As shown in Figure 10, the middle plate 12 has two bent portions 122 and a horizontal support portion 123 that supports the circuit board 5. The two bent portions 122 are arranged on opposite sides of the electronic component assembly 411 along the axial direction of the plug-in port 135 and are both bent toward one side of the circuit board 5. The horizontal support portion 123 is connected between the two bent portions 122 and, together with the two bent portions 122, forms a receiving cavity 121. This allows the middle plate 12 to effectively utilize the distance between the interface device 6 and the first display screen 4. By partially bending itself, the receiving cavity 121 is formed, enabling the assembly of the electronic component assembly 411 and the driver board 41 within the first middle frame 1. The axial direction of the plug-in port 135 is parallel to the length of the first middle frame 1, as shown in the Y direction in Figure 9.

[0108] Furthermore, by supporting the circuit board 5 through the horizontal support portion 123 , a larger contact area can be provided between the circuit board 5 and the middle plate 12 , thereby ensuring that the middle plate 12 has a better supporting effect on the circuit board 5 , so that the middle plate 12 is stably supported on the circuit board 5 .

[0109] The accommodating cavity 121 matches the outer contour of the electronic device assembly 411. For example, the outer contours of the accommodating cavity 121 and the electronic device assembly 411 are identical or similar (as shown in FIG10 ). This ensures that the electronic device assembly 411 can be completely accommodated within the accommodating cavity 121 while saving the space occupied by the electronic device assembly 411 within the first middle frame 1, thereby further improving the space utilization within the electronic device 100.

[0110] It should be noted that, in some embodiments, a notch for accommodating the electronic device group 411 may be further provided on the middle plate 12 . The notch may form the aforementioned accommodating cavity 121 , and may also enable the electronic device group 411 to be assembled in the first middle frame 1 .

[0111] The structure of the electronic device 100 of the present application is further described below by taking the accommodating cavity 121 as an example of a recessed area on the middle plate 12 .

[0112] FIG11 is a partial exploded view of the interior of the electronic device provided in an embodiment of the present application.

[0113] As shown in Figures 10 and 11, the interface device 6 may include a device body 61, the device body 61 having an electrical connection end 611 and a plug end 612 connected to the electrical connection end 611, the electrical connection end 611 is electrically connected to the side of the circuit board 5 facing the plug interface 135, and the plug end 612 is arranged in the middle of the plug interface 135, so that the interface device 6 is electrically connected to the circuit board 5 through the electrical connection end 611, while also ensuring the smooth plugging of the external device into the plug interface 135 and the plug end 612, thereby ensuring smooth conduction between the external device and the electronic device 100.

[0114] As shown in FIG11 , the device body 61 may include, but is not limited to, an insulating member 613 and a plurality of pins 614. The insulating member 613 has a first end and a second end. The first end is overlapped on the circuit board 5, and the second end is inserted into the insertion port 135. The plurality of pins 614 are spaced apart on the insulating member 613 and insulated from each other.

[0115] The first ends of the plurality of pins 614 can extend to the outside of the first end portion and be soldered to the pads on the circuit board 5. The first ends of the plurality of pins 614 and the first end portion together constitute the electrical connection end 611. The second ends of the plurality of pins 614 can extend to the second end portion and together with the second end portion constitute the plug end 612. The plug end 612 can be referred to as the tongue of the interface device 6 to achieve electrical connection between the electronic device 100 and an external device at the interface device 6.

[0116] It should be noted that, in some embodiments, as shown in Figure 11, the interface device 6 can also be provided with a sealing ring 64, which can be sleeved on the circumferential side of the plug-in end 612, so that when the plug-in end 612 is inserted into the plug-in port 135, it can be sealed in the plug-in port 135 by the sealing ring 64 to prevent liquid from entering the interior of the electronic device 100 through the plug-in port 135.

[0117] There is a penetration space 124 between the circuit board 5 and the plug interface 135, which is connected to the plug interface 135. The plug end 612 is bent toward one side of the first display screen 4, and passes through the penetration space 124 and is inserted into the middle of the plug interface 135 (as shown in Figure 10), so that the bending of the plug end 612 can ensure that the interface device 6 can still be inserted into the middle of the plug interface 135 when it is located on the component surface 52, thereby ensuring the smooth connection of the external device between the plug interface 135 and the plug end 612.

[0118] An opening 53 is provided on the edge of the circuit board 5 facing the plug interface 135. A through-space 124 is defined between the edge of the opening 53 and the first middle frame 1. Specifically, the edge of the opening 53 of the circuit board 5, the middle plate 12, and the frame 13 of the first middle frame 1 together define the through-space 124. The electrical connection terminal 611 overlaps the circuit board 5 to electrically connect the electrical connection terminal 611 to the circuit board 5. The plugging terminal 612 is retained within the opening 53 and bent within the through-space 124 toward the side of the first display screen 4, allowing the plugging terminal 612 to pass through the through-space 124 and be positioned in the middle of the plug interface 135.

[0119] Moreover, by having the plug-in end 612 locked in the opening 53, not only can the electrical connection between the electrical connection end 611 and the circuit board 5 be facilitated, but the interface device 6 can also reuse a certain space with the circuit board 5 in the thickness direction of the electronic device 100, so as to further reduce the height of the interface device 6 on the circuit board 5 to meet the lightweight design of the electronic device 100.

[0120] Referring to Figure 11 and in combination with Figure 10, the middle plate 12 is bent toward one side of the first display screen 4 at the position corresponding to the opening 53 to increase the penetration space 124, so that the plug-in end 612 is bent toward one side of the first display screen 4, thereby ensuring that the plug-in end 612 can be penetrated into the middle of the plug interface 135, while allowing the interface device 6 to reuse the space occupied by the driving board 41 in the first middle frame 1 in the thickness direction of the electronic device 100, so as to further meet the lightweight and thin design of the electronic device 100.

[0121] FIG12 is a second schematic diagram of the assembly of an interface device in an electronic device according to an embodiment of the present application.

[0122] As shown in Figures 11 and 12, the interface device 6 also includes a cover plate 62, which covers the electrical connection end 611 and is connected to the circuit board 5 so that the cover plate 62 is pressed on the electrical connection end 611 to enhance the stability of the electrical connection between the electrical connection end 611 and the circuit board 5. At the same time, the cover plate 62 can also cover the electrical connection end 611 to protect the electrical connection end 611.

[0123] As shown in Figure 12, at least two claws 621 can be provided on the peripheral side of the cover plate 62, and the circuit board 5 is provided with a slot 54 at the position corresponding to the claw 621. The claw 621 can be inserted into the slot 54 to realize the assembly of the cover plate 62 on the circuit board 5.

[0124] FIG13 is a schematic diagram showing the structure of the electronic device in FIG10 at different viewing angles.

[0125] As shown in FIG13 , in some embodiments, the projections of the interface device 6 and the electronic device group 411 on the circuit board 5 at least partially overlap, so that the electronic device group 411 can reuse the space occupied by the interface device 6 in the length direction of the first middle frame 1, thereby saving the space occupied by the electronic device group 411 and the interface device 6 in the length direction of the first middle frame 1. The length direction of the first middle frame 1 can be referred to as the Y direction in FIG9 .

[0126] The battery is usually arranged on the driving board 41 in the first middle frame 1 and is located on the side of the electronic device group 411 away from the interface device 6. In this way, after the space occupied by the electronic device group 411 and the interface device 6 in the length direction of the first middle frame 1 is saved, the battery can be made larger in the first middle frame 1 to increase the battery capacity. While making the electronic device 100 lighter and thinner, it can also further meet the large power demand of the electronic device 100.

[0127] Among them, one end of the interface device 6 electrically connected to the circuit board 5 (the end where the electrical connection end 611 of the interface device 6 is located) has a first projection surface 63 on the circuit board 5, and at least part of the electronic device group 411 is located within the first projection surface 63, so that the projections of the interface device 6 and the electronic device group 411 on the circuit board 5 can at least partially overlap, so as to reduce or avoid the impact of the interface device 6 on the thickness of the electronic device 100 while being able to meet the large power requirements of the electronic device 100.

[0128] As shown in Figure 13, in some embodiments, part of the electronic device group 411 can be located within the first projection surface 63, so that the projections of the electronic device group 411 and the interface device 6 on the circuit board 5 can partially overlap. The length L of the overlapping area of ​​the projections of the electronic device group 411 and the interface device 6 on the circuit board 5 can include but is not limited to 1mm, 2mm, 3mm, etc., so as to save space equal to the length L in the length direction of the first middle frame 1 to meet the larger battery capacity of the electronic device 100 (such as a foldable electronic device). For example, when the length L is equal to 3mm, the electronic device group 411 and the interface device 6 can save 3mm of occupied space in the length direction of the first middle frame 1. The direction of the length L is parallel to the length direction of the first middle frame 1.

[0129] With the development of technology, after the size of the interface device 6 group in the length direction of the first middle frame 1 is gradually reduced, the electronic device group 411 can also be completely located within the first projection surface 63, so that the electrical connection end 611 and the projection of the electronic device group 411 on the circuit board 5 can also completely overlap, thereby further saving the space occupied by the electronic device group 411 and the interface device 6 in the length direction of the first middle frame 1, thereby further increasing the capacity of the battery.

[0130] The electronic device 100 provided in the embodiment of the present application can increase the distance between the interface device 6 and the first display screen 4 by flipping the interface device 6 and electrically connecting it to the side of the circuit board 5 away from the first display screen 4, and effectively utilize the distance between the interface device 6 and the first display screen 4. On the basis of meeting the requirements of the electronic device 100 to be lightweight and thin, the electronic device group 411 and the driving board 41 can be accommodated in the first middle frame 1.
