Description

Technical Field

[0001] This application relates to the field of electronic product technology, and in particular to an electronic device and circuit board assembly. Background Technology

[0002] With the development of electronic technology, the layout space of motherboards in mobile phones and other electronic devices is becoming increasingly limited. A motherboard typically includes a printed circuit board (PCB) and functional modules integrated on it. Furthermore, electronic components such as flashlights, wireless charging modules, and NFC (Near Field Communication) modules are usually electrically connected to the motherboard's PCB via flexible printed circuit boards (FPCs). This electrical connection is achieved through methods such as soldering springs onto the flexible circuit board.

[0003] To accommodate the internal space layout of electronic devices such as mobile phones, the printed circuit board of the motherboard is sometimes formed into a narrow strip. Usually, the structural strength of the narrow strip of the motherboard is low, and the motherboard cannot place electronic components in this area, which reduces the space utilization of the electronic device. Summary of the Invention

[0004] This application provides an electronic device and a circuit board assembly to improve the space utilization of the electronic device.

[0005] In a first aspect, this application provides an electronic device, which includes a housing and a circuit board assembly. The housing has a receiving cavity. The circuit board assembly includes a printed circuit board, a first reinforcing plate, a second reinforcing plate, and electronic components. The printed circuit board is housed in the receiving cavity and connected to the housing. The first reinforcing plate is made of a conductive material, and its surface abuts against the surface of the printed circuit board, and the first reinforcing plate is fixedly connected to the printed circuit board. The second reinforcing plate is also made of a conductive material, and its surface abuts against the surface of the printed circuit board, and the second reinforcing plate is fixedly connected to the printed circuit board. At least one of the first and second reinforcing plates is electrically connected to the printed circuit board, and the first and second reinforcing plates are spaced apart. The electronic components include a first conductive terminal and a second conductive terminal, the first conductive terminal being electrically connected to the first reinforcing plate, and the second conductive terminal being electrically connected to the second reinforcing plate.

[0006] The electronic device provided in this application abuts the surface of a first reinforcing plate against the surface of a printed circuit board (PCB), and the surface of a second reinforcing plate against the PCB. At least one of the first and second reinforcing plates, both made of conductive material, is electrically connected to the PCB. The first and second reinforcing plates are spaced apart. A first conductive terminal is electrically connected to the first reinforcing plate, and a second conductive terminal is electrically connected to the second reinforcing plate. This not only enhances the structural strength of the PCB through the first and second reinforcing plates, but also connects signal circuits between the PCB and electronic devices through the spaced-apart first and second reinforcing plates. This improves the space utilization of electronic devices on the PCB and enhances the overall space utilization of the electronic device.

[0007] In one possible implementation, the printed circuit board includes a circuit board body and a circuit board extension strip connected together. The circuit board extension strip extends in a direction away from the circuit board body. The width of one end of the circuit board body facing the circuit board extension strip is greater than the width of the circuit board extension strip. At least one of the first reinforcing plate and the second reinforcing plate is configured to be fixedly connected at one end to the circuit board body and at the other end to the circuit board extension strip.

[0008] In this implementation, the electronic device improves the layout utilization on the circuit board extension strip by making the width of the end of the circuit board body facing the circuit board extension strip greater than the width of the circuit board extension strip. At least one of the first reinforcing plate and the second reinforcing plate is configured to be fixedly connected to the circuit board body at one end and fixedly connected to the circuit board extension strip at the other end. It also helps the printed circuit board to better adapt to the spatial layout of the electronic device by using the narrower circuit board extension strip.

[0009] In another possible implementation, at least one of the first reinforcing plate and the second reinforcing plate includes a first reinforcing segment and a second reinforcing segment connected together. The first reinforcing segment is fixedly connected to the circuit board body, and the second reinforcing segment is fixedly connected to the circuit board extension strip. An included angle is formed between the first reinforcing segment and the second reinforcing segment.

[0010] In this implementation, the first reinforcing section is fixedly connected to the circuit board body, and the second reinforcing section is fixedly connected to the circuit board extension strip. The first reinforcing section and the second reinforcing section are arranged to form an angle, which is beneficial for the first reinforcing section and the second reinforcing section to improve the structural strength of the circuit board extension strip in different directions, and is beneficial for the circuit board extension strip to connect more and heavier electronic devices.

[0011] In another possible implementation, the first reinforcing plate includes a first reinforcing segment and a second reinforcing segment, and the second reinforcing plate includes a third reinforcing segment. One end of the third reinforcing segment is fixedly connected to the circuit board body, and the other end of the third reinforcing segment is fixedly connected to the circuit board extension strip. The second reinforcing segment and the third reinforcing segment are spaced apart along the width direction of the circuit board extension strip. The width directions of the second reinforcing segment and the third reinforcing segment are perpendicular to the extension direction of the circuit board extension strip, respectively, and the width of the second reinforcing segment is greater than the width of the third reinforcing segment.

[0012] In this implementation, the relatively wide second reinforcing section can provide a larger connection space for electronic devices, while the relatively narrow third reinforcing section can make full use of the space of the circuit board extension strip to improve structural strength.

[0013] In another possible implementation, the second reinforcing plate further includes a fourth reinforcing segment, the end of the third reinforcing segment away from the circuit board body is connected to the fourth reinforcing segment, the fourth reinforcing segment and the third reinforcing segment are arranged to form an angle, and the fourth reinforcing segment is fixedly connected to the circuit board extension strip; the second reinforcing segment and the fourth reinforcing segment are spaced apart along the extension direction of the circuit board extension strip.

[0014] In this implementation, the fourth reinforcing segment and the third reinforcing segment form an angle, which helps the third and fourth reinforcing segments to improve the structural strength of the circuit board extension strip in different directions, and helps the circuit board extension strip connect more and heavier electronic devices. In addition, the fourth reinforcing segment, which is spaced apart from the second reinforcing segment, can provide a larger connection space for electronic devices.

[0015] In another possible implementation, the first conductive terminal and the second conductive terminal are arranged along the extension direction of the circuit board extension strip, the first conductive terminal is electrically connected to the second reinforcing segment, and the second conductive terminal is electrically connected to the fourth reinforcing segment.

[0016] In this implementation, the first conductive terminal and the second conductive terminal are arranged along the extension direction of the circuit board extension strip, which reduces the limitation of the width of the circuit board extension strip on the connection space of the first conductive terminal and the second conductive terminal, and helps to provide a larger connection space for the first conductive terminal and the second conductive terminal on the circuit board extension strip.

[0017] In another possible implementation, one end of the first reinforcing plate is fixedly connected to the circuit board body, and the other end of the first reinforcing plate is fixedly connected to the circuit board extension strip; the second reinforcing plate is fixedly connected to the circuit board extension strip, and the second reinforcing plate is spaced apart from the circuit board body.

[0018] In this implementation, the circuit board assembly can enhance the structural strength of the printed circuit board through the first reinforcing plate, and the second reinforcing plate can be spaced apart from the circuit board body to reduce the width occupied by the second reinforcing plate on the circuit board extension strip, which is beneficial to setting a narrower circuit board extension strip on the printed circuit board.

[0019] In another possible implementation, along the extension direction of the circuit board extension strip, the end of the first reinforcing plate facing the second reinforcing plate has a notch; the end of the second reinforcing plate facing the first reinforcing section has an extension section that extends into the notch.

[0020] In this implementation, the second reinforcing plate has an extension section at one end facing the first reinforcing section. The extension section extends into the notch of the first reinforcing plate, which is beneficial to improve the structural strength of the circuit board extension strip in different directions and to enable the circuit board extension strip to connect more and heavier electronic devices.

[0021] In another possible implementation, the second reinforcing plate further includes a body segment, and the extension segment and the body segment are arranged along the extension direction of the circuit board extension strip; the width direction of the extension segment and the width direction of the body segment are perpendicular to the extension direction of the circuit board extension strip, and the width of the body segment is greater than the width of the extension segment.

[0022] In this implementation, the width of the body segment is greater than the width of the extension segment, which is beneficial for improving the structural strength of the circuit board extension strip in different directions through the body segment and the extension segment, and is beneficial for connecting more and heavier electronic devices to the circuit board extension strip.

[0023] In another possible implementation, the first conductive terminal and the second conductive terminal are arranged along the extension direction of the circuit board extension strip. The first conductive terminal is electrically connected to the first reinforcing plate, and the second conductive terminal is electrically connected to the body segment. The first conductive terminal, the notch, the extension segment and the body segment are arranged sequentially along the extension direction of the circuit board extension strip.

[0024] In this implementation, the first conductive terminal, the notch, the extension section and the body section are arranged sequentially along the extension direction of the circuit board extension strip. This is beneficial to increase the distance between the first conductive terminal and the second conductive terminal in the extension direction of the circuit board extension strip. This not only improves the structural strength through the body section and the extension section, but also provides a larger connection space for the first conductive terminal and the second conductive terminal at a position far away from the notch and the extension section.

[0025] In another possible implementation, the width of the circuit board extension strip is less than or equal to 2.5 mm.

[0026] In this implementation, the width of the circuit board extension strip is relatively narrow, which makes the circuit board assembly suitable for narrower spaces and improves the applicability of the circuit board assembly.

[0027] In another possible implementation, the electronic device includes a device body and a connecting circuit board. One end of the connecting circuit board is connected to the device body, and the other end of the connecting circuit board is provided with a first conductive terminal and a second conductive terminal. The first conductive terminal and the second conductive terminal are respectively disposed between the printed circuit board and the connecting circuit board. The circuit board assembly also includes a bracket, which is fixedly connected to the printed circuit board. Part of the bracket is disposed on the side of the connecting circuit board facing away from the printed circuit board, and the bracket is fixedly connected to the connecting circuit board.

[0028] In this implementation, the first conductive terminal and the second conductive terminal are respectively disposed between the printed circuit board and the connecting circuit board of the electronic device, which is beneficial to improving the space utilization of the circuit board assembly; some brackets are disposed on the side of the connecting circuit board facing away from the printed circuit board, and the brackets are fixedly connected to the connecting circuit board, which is beneficial to improving the connection stability of the electronic device.

[0029] In another possible implementation, the circuit board assembly also includes an abutment plate disposed between the connecting circuit board and a portion of the bracket; one side of the abutment plate is fixedly connected to the connecting circuit board, and the other side of the abutment plate is fixedly connected to the bracket.

[0030] In this implementation, one side of the abutment plate is fixedly connected to the connecting circuit board, and the other side of the abutment plate is fixedly connected to the bracket, which helps to further improve the connection stability of electronic devices.

[0031] In another possible implementation, at least one of the first conductive terminal and the second conductive terminal includes a compression spring that abuts against the first reinforcing plate or the second reinforcing plate, and the compression spring is used to keep the printed circuit board and the connecting circuit board away from each other.

[0032] In this implementation, the circuit board assembly can improve the connection stability of the electrical connection position through the compression spring used to keep the printed circuit board and the connecting circuit board away from each other, and can also provide greater support strength for the compression spring through the first reinforcing plate, the second reinforcing plate and the bracket.

[0033] Secondly, this application provides a circuit board assembly for use in an electronic device. The electronic device includes a housing and the circuit board assembly. The housing has a receiving cavity. The circuit board assembly includes a printed circuit board, a first reinforcing plate, a second reinforcing plate, and electronic components. The printed circuit board is used to be housed in the receiving cavity and is connected to the housing. The first reinforcing plate is made of a conductive material, and its surface abuts against the surface of the printed circuit board. The first reinforcing plate is fixedly connected to the printed circuit board. The second reinforcing plate is also made of a conductive material, and its surface abuts against the surface of the printed circuit board. The second reinforcing plate is fixedly connected to the printed circuit board. At least one of the first and second reinforcing plates is electrically connected to the printed circuit board, and the first and second reinforcing plates are spaced apart. The electronic components include a first conductive terminal and a second conductive terminal. The first conductive terminal is electrically connected to the first reinforcing plate, and the second conductive terminal is electrically connected to the second reinforcing plate.

[0034] The circuit board assembly provided in this application abuts the surface of a first reinforcing plate against the surface of a printed circuit board, and the surface of a second reinforcing plate against the surface of a printed circuit board. At least one of the first and second reinforcing plates, both made of conductive material, is electrically connected to the printed circuit board. The first and second reinforcing plates are spaced apart. A first conductive terminal is electrically connected to the first reinforcing plate, and a second conductive terminal is electrically connected to the second reinforcing plate. This assembly not only enhances the structural strength of the printed circuit board through the first and second reinforcing plates, but also connects signal circuits between the printed circuit board and electronic devices through the spaced-apart first and second reinforcing plates. This improves the space utilization of electronic devices on the printed circuit board and enhances the space utilization of the corresponding electronic equipment. Attached Figure Description

[0044] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0045] With the development of electronic technology, the layout space of motherboards in mobile phones and other electronic devices is becoming increasingly limited. A motherboard typically includes a printed circuit board (PCB) and functional modules integrated on it. Furthermore, electronic components such as flashlights, wireless charging modules, and NFC (Near Field Communication) modules are usually electrically connected to the motherboard's PCB via flexible printed circuit boards (FPCs). This electrical connection is achieved through methods such as soldering springs onto the flexible circuit board.

[0046] To accommodate the internal space layout of electronic devices such as mobile phones, the printed circuit board of the motherboard is sometimes formed into a narrow strip. Usually, the structural strength of the narrow strip of the motherboard is low, and the motherboard cannot place electronic components in this area, which reduces the space utilization of the electronic device.

[0047] Therefore, an electronic device and circuit board assembly are proposed to improve the space utilization of electronic devices. The electronic device provided in this application can include, but is not limited to, mobile phones, tablets, laptops, PCs (Personal Computers), Ultra Mobile Personal Computers (UMPCs), handheld computers, walkie-talkies, netbooks, POS machines, Personal Digital Assistants (PDAs), wearable devices, security equipment, televisions, and speakers, etc., as mobile or fixed terminals. Mobile phones can include candybar phones and foldable phones, etc., and wearable devices can include VR glasses (Virtual Reality), smart glasses, headphones, smartwatches, and smart bracelets, etc. The embodiments of this application mainly use mobile phones as an example to describe the electronic device. Without obvious conflict, the following structure can also be applied to other electronic devices besides mobile phones.

[0048] Reference Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A perspective view of an electronic device 10 according to one embodiment is shown. Figure 2 An exploded view of the electronic device 10 in this embodiment is shown. The electronic device 10 includes a housing 100 and a circuit board assembly 200, which includes a printed circuit board 210. The X-axis corresponds to the width of the electronic device 10, the Y-axis corresponds to the length, and the Z-axis corresponds to the thickness. The housing 100 may include a middle frame and a back cover 120, which may be made of materials such as plastic or metal. The middle frame may include a side frame 111 and a middle plate 112. The middle plate 112 is located inside the side frame 111, and the edge of the side frame 111 is connected to the middle plate 112. The side frame 111 may be arranged around the edge of the middle plate 112, thus providing a receiving cavity 113 in the housing 100. It is understood that the side frame 111 and the middle plate 112 may be manufactured using a one-piece molding method. Alternatively, the middle frame may not include the middle plate 112.

[0049] When the electronic device 10 has a display function, the electronic device 10 may also include a display screen 130. The display screen 130 may include a light-transmitting plate 131 and a display panel 132, which are stacked together. The edge of the light-transmitting plate 131 can be fixed to one side opening of the frame 111 by means of adhesive or the like, so that the light-transmitting plate 131, the frame 111 and the back cover 120 together form a receiving cavity 113, which can be understood as making the housing 100 have a receiving cavity 113.

[0050] The light-transmitting plate 131 can be a glass plate, sapphire plate, etc., and the display panel 132 can be a flexible display screen or a rigid display screen. In some embodiments, the display panel 132 can be an organic light-emitting diode (OLED) panel, an active matrix organic light-emitting diode (AMOLED) panel, a quantum dot light-emitting diode (QLED) panel, or a liquid crystal display (LCD) panel.

[0051] It is understandable that when the electronic device 10 does not have a display function, the electronic device 10 may also not have the aforementioned display screen 130.

[0052] The aforementioned mid-frame (which may include a frame 111 and a middle plate 112) and components such as a printed circuit board 210, a battery 300, a camera 400, and a USB device can be disposed between the display screen 130 and the back cover. The mid-frame can serve as a mounting frame for the electronic device 10, and components such as the printed circuit board 210, battery 300, camera 400, USB device, and speaker can be mounted on the mid-frame, for example, on the middle plate 112 or the frame 111.

[0053] The printed circuit board 210 can be accommodated in the aforementioned receiving cavity 113 and is connected to the housing 100. For example, the electronic device 10 may also include a bracket 251 and fasteners, wherein the fasteners may be screws or the like; wherein the middle plate 112, the printed circuit board 210, and the bracket 251 can be arranged sequentially, and the fasteners can fix the middle plate 112, the printed circuit board 210, and the bracket 251 to each other. Specifically, the middle plate 112 may have threaded holes, and the printed circuit board 210 may have through holes. The fasteners can pass through the through holes of the printed circuit board 210 and be threadedly connected to the threaded holes on the middle plate 112, thereby fixing the middle plate 112, the printed circuit board 210, and the bracket 251 to each other.

[0054] It is understood that the electronic device 10 may also be without the aforementioned bracket 251. For example, the electronic device 10 may directly fix the printed circuit board 210 to the middle plate 112 or the frame 111 using fasteners. This embodiment does not limit this.

[0055] Furthermore, in the electronic device 10 provided in this application embodiment, the printed circuit board 210 may include a main circuit board (also called a motherboard) and a secondary circuit board. The main circuit board may be used to integrate a control chip, which may be configured as an application processor (AP), etc. In some embodiments, the main circuit board may be electrically connected to the display screen 130, and the main circuit board may be used to enable the display screen 130 to display specific images or videos.

[0056] The secondary circuit board can be used to connect electronic components such as antennas (e.g., 5G antennas) and radio frequency front-ends. The secondary circuit board can also be electrically connected to the main circuit board through flexible printed circuits (FPCs), wires, or enameled wires to realize data and signal transmission between the secondary circuit board and the main circuit board.

[0057] Furthermore, the speaker can be electrically connected to the aforementioned sub-circuit board to receive electrical signals used to generate sound and emit sound. Specifically, the audio signal type electrical signal sent by the main circuit board can be transmitted to the speaker via the sub-circuit board and converted into sound waves by the speaker for output, which can be output through the sound outlet on the housing 100.

[0058] Understandable, Figure 1 and Figure 2 The diagram only schematically illustrates some of the components included in the electronic device 10; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 and Figure 2 Restrictions.

[0059] In addition, refer to Figure 3 or Figure 6 ,in Figure 3 A perspective view of a partial structure of the circuit board assembly 200 in one embodiment is shown. Figure 6A perspective view of a partial structure of the circuit board assembly 200 in another embodiment is shown; wherein the circuit board assembly 200 further includes a first reinforcing plate 220, a second reinforcing plate 230, and electronic components; a printed circuit board 210 is housed in a receiving cavity 113 and is connected to the housing 100; the first reinforcing plate 220 is made of conductive material, and its surface abuts against the surface of the printed circuit board 210, and the first reinforcing plate 220 is fixedly connected to the printed circuit board 210; the second reinforcing plate 230 is made of conductive material. The second reinforcing plate 230 abuts against the surface of the printed circuit board 210, and the second reinforcing plate 230 is fixedly connected to the printed circuit board 210; at least one of the first reinforcing plate 220 and the second reinforcing plate 230 is electrically connected to the printed circuit board 210, and the first reinforcing plate 220 and the second reinforcing plate 230 are spaced apart; the electronic device includes a first conductive terminal 241 and a second conductive terminal 242, the first conductive terminal 241 is electrically connected to the first reinforcing plate 220, and the second conductive terminal 242 is electrically connected to the second reinforcing plate 230.

[0060] The first reinforcing plate 220 and the second reinforcing plate 230 can be understood as plates used to structurally reinforce the printed circuit board 210. For example, the first reinforcing plate 220 and the second reinforcing plate 230 can be respectively set as metal sheets, such as steel sheets, copper alloy sheets, etc. The surface of the first reinforcing plate 220 abuts against the surface of the printed circuit board 210, and the surface of the second reinforcing plate 230 abuts against the surface of the printed circuit board 210. This can be understood as the first reinforcing plate 220 and the second reinforcing plate 230 being respectively attached to the surface of the printed circuit board 210.

[0061] The first reinforcing plate 220 is fixedly connected to the printed circuit board 210, and the second reinforcing plate 230 is fixedly connected to the printed circuit board 210. This connection can be achieved by fixing the plate to the conductive layer of the printed circuit board 210 (specifically, by welding or other methods), or by bonding the plate to the printed circuit board 210. At least one of the first reinforcing plate 220 and the second reinforcing plate 230 is electrically connected to the printed circuit board 210. This can be understood as at least one of the first reinforcing plate 220 and the second reinforcing plate 230 being fixedly connected to the conductive layer of the printed circuit board 210. For example, one of the first reinforcing plate 220 and the second reinforcing plate 230 can be fixedly connected to the conductive layer of the printed circuit board 210, or both the first reinforcing plate 220 and the second reinforcing plate 230 can be fixedly connected to the conductive layer of the printed circuit board 210.

[0062] It is understood that electronic devices can be grounded or connected to signal circuits via first conductive terminals 241 and second conductive terminals 242 respectively through first reinforcing plates 220 and second reinforcing plates 230. Furthermore, the circuit board assembly 200 may include at least two first reinforcing plates 220 and / or at least two second reinforcing plates 230, and the electronic devices may include at least two first conductive terminals 241 and / or at least two second conductive terminals 242, with each first conductive terminal 241 and second conductive terminal 242 connected to its corresponding first reinforcing plate 220 and second reinforcing plate 230. Here, electronic devices can be understood as devices capable of performing certain electrical functions, including but not limited to flashlights, wireless charging modules, and NFC modules.

[0063] In this embodiment, the electronic device 10 abuts the surface of the first reinforcing plate 220 against the surface of the printed circuit board 210, and the surface of the second reinforcing plate 230 against the surface of the printed circuit board 210. At least one of the first reinforcing plate 220 and the second reinforcing plate 230, both made of conductive material, is electrically connected to the printed circuit board 210. The first reinforcing plate 220 and the second reinforcing plate 230 are spaced apart. The first conductive terminal 241 is electrically connected to the first reinforcing plate 220, and the second conductive terminal 242 is electrically connected to the second reinforcing plate 230. This not only enhances the structural strength of the printed circuit board 210 through the first reinforcing plate 220 and the second reinforcing plate 230, but also connects the signal circuit between the printed circuit board 210 and the electronic devices through the spaced-apart first reinforcing plate 220 and the second reinforcing plate 230. This improves the space utilization of the electronic devices on the printed circuit board 210 and enhances the space utilization of the electronic device 10.

[0064] In some implementations, refer to Figure 3 or Figure 6 The printed circuit board 210 may include a connected circuit board body 211 and a circuit board extension strip 212. For example, the circuit board body 211 and the circuit board extension strip 212 may be connected by being integrally molded. The circuit board extension strip 212 extends in a direction away from the circuit board body 211, for example... Figure 3 The circuit board extension strip 212 extends to the right along the X-axis; the width of the end of the circuit board body 211 facing the circuit board extension strip 212 is greater than the width of the circuit board extension strip 212, for example... Figure 3 The width of the right end of the circuit board body 211 is greater than the width of the circuit board extension strip 212; at least one of the first reinforcing plate 220 and the second reinforcing plate 230 is configured such that one end is fixedly connected to the circuit board body 211 and the other end is fixedly connected to the circuit board extension strip 212, for example... Figure 3The first reinforcing plate 220 and the second reinforcing plate 230 are respectively configured such that one end is fixedly connected to the circuit board body 211 and the other end is fixedly connected to the circuit board extension strip 212; of course, one of the first reinforcing plate 220 and the second reinforcing plate 230 can also be configured such that one end is fixedly connected to the circuit board body 211 and the other end is fixedly connected to the circuit board extension strip 212, for example. Figure 6 Only the first reinforcing plate 220 is configured such that one end is fixedly connected to the circuit board body 211 and the other end is fixedly connected to the circuit board extension strip 212.

[0065] In this embodiment, the electronic device 10 improves the layout utilization on the circuit board extension strip 212 by making the width of one end of the circuit board body 211 facing the circuit board extension strip 212 greater than the width of the circuit board extension strip 212, and at least one of the first reinforcing plate 220 and the second reinforcing plate 230 is configured to be fixedly connected at one end to the circuit board body 211 and at the other end to the circuit board extension strip 212. This also helps the printed circuit board 210 to better adapt to the spatial layout of the electronic device 10 by using the narrower circuit board extension strip 212.

[0066] In some implementations, refer to Figure 3 , Figure 4 and Figure 5 or refer to Figure 6 , Figure 7 and Figure 8 At least one of the first reinforcing plate 220 and the second reinforcing plate 230 includes a first reinforcing segment 221 and a second reinforcing segment 222 connected together. For example, the first reinforcing plate 220 can be configured to include a first reinforcing segment 221 and a second reinforcing segment 222 connected together, and the second reinforcing plate 230 can also be configured to include a first reinforcing segment 221 and a second reinforcing segment 222 connected together. The first reinforcing segment 221 is fixedly connected to the circuit board body 211, for example, by welding to the conductive layer of the circuit board body 211 or by bonding to the circuit board body 211. The second reinforcing segment 222 is fixedly connected to the circuit board extension strip 212, for example, by welding to the conductive layer of the circuit board extension strip 212 or by bonding to the circuit board extension strip 212. The first reinforcing segment 221 and the second reinforcing segment 222 form an included angle between them. Figure 5 The first reinforcing segment 221 and the second reinforcing segment 222 are perpendicular to each other, that is, the included angle can be set to 90 degrees; of course, the included angle can be set to other angles greater than 0 degrees and less than 180 degrees, such as 30 degrees, 60 degrees, 120 degrees, 150 degrees, etc., and this embodiment does not limit this.

[0067] In this embodiment, the first reinforcing segment 221 is fixedly connected to the circuit board body 211, and the second reinforcing segment 222 is fixedly connected to the circuit board extension strip 212. The first reinforcing segment 221 and the second reinforcing segment 222 form an angle between them, which is beneficial for the first reinforcing segment 221 and the second reinforcing segment 222 to improve the structural strength of the circuit board extension strip 212 in different directions. For example, it can improve the bending resistance of the circuit board extension strip 212 in the Y-axis direction and the bending resistance of the circuit board extension strip 212 in the Z-axis direction, thereby enabling the circuit board extension strip 212 to connect more and heavier electronic devices.

[0068] In some implementations, refer to Figure 3 , Figure 4 and Figure 5 The first reinforcing plate 220 includes a first reinforcing segment 221 and a second reinforcing segment 222, and the second reinforcing plate 230 includes a third reinforcing segment 231; one end of the third reinforcing segment 231 is fixedly connected to the circuit board body 211, and the other end of the third reinforcing segment 231 is fixedly connected to the circuit board extension strip 212; for example Figure 5 The left end of the third reinforcing section 231 is fixedly connected to the circuit board body 211, and the right end of the third reinforcing section 231 is fixedly connected to the circuit board extension strip 212. Along the width direction of the circuit board extension strip 212, for example along... Figure 5 In the Y-axis direction, the second reinforcing segment 222 and the third reinforcing segment 231 are spaced apart; the width direction of the second reinforcing segment 222 and the width direction of the third reinforcing segment 231 are perpendicular to the extension direction of the circuit board extension strip 212, for example... Figure 3 The width direction of the second reinforcing segment 222 and the width direction of the third reinforcing segment 231 are respectively along the Y-axis direction, and the extension direction of the circuit board extension strip 212 is along the X-axis direction; wherein, the width of the second reinforcing segment 222 is greater than the width of the third reinforcing segment 231, which can be understood as the second reinforcing segment 222 being relatively wider and the third reinforcing segment 231 being relatively narrower.

[0069] In this embodiment, the relatively wider second reinforcing section 222 can provide a larger connection space for electronic devices, such as providing a larger soldering space; the relatively narrower third reinforcing section 231 can make full use of the space of the circuit board extension strip 212 to improve structural strength, for example... Figure 5 The relatively narrow third reinforcing section 231 can make full use of the space of the circuit board extension strip 212 in the Y-axis direction.

[0070] In some implementations, refer to Figure 3 , Figure 4 and Figure 5The second reinforcing plate 230 also includes a fourth reinforcing section 232, and the end of the third reinforcing section 231 away from the circuit board body 211 is connected to the fourth reinforcing section 232, for example... Figure 5 The right end of the third reinforcing segment 231 is connected to the fourth reinforcing segment 232; the fourth reinforcing segment 232 and the third reinforcing segment 231 form an angle between them, for example... Figure 5 The fourth reinforcing segment 232 is perpendicular to the third reinforcing segment 231, meaning the included angle can be set to 90 degrees. Of course, this included angle can be set to other angles greater than 0 degrees and less than 180 degrees, such as 30 degrees, 60 degrees, 120 degrees, 150 degrees, etc., and this embodiment does not limit this. Furthermore, the fourth reinforcing segment 232 is fixedly connected to the circuit board extension strip 212, for example, by welding to the conductive layer of the circuit board extension strip 212 or by bonding to the circuit board extension strip 212; along the extension direction of the circuit board extension strip 212, for example along... Figure 5 In the X-axis direction, the second reinforcement segment 222 and the fourth reinforcement segment 232 are set at intervals.

[0071] In this embodiment, the fourth reinforcing segment 232 and the third reinforcing segment 231 are arranged at an angle, which is beneficial for the third reinforcing segment 231 and the fourth reinforcing segment 232 to improve the structural strength of the circuit board extension strip 212 in different directions. For example, it can improve the bending resistance of the circuit board extension strip 212 in the Y-axis direction and the bending resistance of the circuit board extension strip 212 in the Z-axis direction, thereby enabling the circuit board extension strip 212 to connect more and heavier electronic devices. In addition, the fourth reinforcing segment 232, which is spaced apart from the second reinforcing segment 222, can provide a larger connection space for electronic devices, such as providing a larger soldering space.

[0072] In some implementations, refer to Figure 3 The first conductive terminal 241 and the second conductive terminal 242 are arranged along the extension direction of the circuit board extension strip 212, for example, along... Figure 3 The first conductive terminal 241 is electrically connected to the second reinforcing segment 222, for example, by welding or abutting the first conductive terminal 241 to the second reinforcing segment 222; the second conductive terminal 242 is electrically connected to the fourth reinforcing segment 232, for example, by welding or abutting the second conductive terminal 242 to the fourth reinforcing segment 232.

[0073] In this embodiment, the first conductive terminal 241 and the second conductive terminal 242 are arranged along the extending direction of the circuit board extension strip 212, which reduces the limitation of the width of the circuit board extension strip 212 on the connection space of the first conductive terminal 241 and the second conductive terminal 242. For example, Figure 3The first conductive terminal 241 and the second conductive terminal 242 are less restricted in space in the Y-axis direction of the circuit board extension strip 212, which is beneficial to provide more connection space for the first conductive terminal 241 and the second conductive terminal 242 on the circuit board extension strip 212, such as providing more soldering space.

[0074] In other embodiments, reference is made to... Figure 6 , Figure 7 and Figure 8 One end of the first reinforcing plate 220 is fixedly connected to the circuit board body 211, for example, by welding to the conductive layer of the circuit board body 211 or by bonding to the circuit board body 211; the other end of the first reinforcing plate 220 is fixedly connected to the circuit board extension strip 212, for example, by welding to the conductive layer of the circuit board extension strip 212 or by bonding to the circuit board extension strip 212; for example Figure 6 The left end of the first reinforcing plate 220 is fixedly connected to the circuit board body 211, and the right end of the first reinforcing plate 220 is fixedly connected to the circuit board extension strip 212. In addition, the second reinforcing plate 230 is fixedly connected to the circuit board extension strip 212, for example, by welding to the conductive layer of the circuit board extension strip 212 or by bonding to the circuit board body 211. The second reinforcing plate 230 and the circuit board body 211 are spaced apart, for example, spaced apart along the X-axis direction in the figure.

[0075] In this embodiment, the circuit board assembly 200 can enhance the structural strength of the printed circuit board 210 through the first reinforcing plate 220, and the second reinforcing plate 230 can be spaced apart from the circuit board body 211 to reduce the width occupied by the second reinforcing plate 230 on the circuit board extension strip 212. This facilitates the provision of a narrower circuit board extension strip 212 on the printed circuit board 210, for example... Figure 6 , Figure 7 and Figure 8 The circuit board extension strip 212 in the middle is relative to Figure 3 , Figure 4 and Figure 5 It can be set to be narrower.

[0076] In some implementations, refer to Figure 6 , Figure 7 and Figure 8Along the extension direction of the circuit board extension strip 212, for example, along the X-axis direction in the figure, the first reinforcing plate 220 has a notch 223 at one end facing the second reinforcing plate 230, for example, the right end of the first reinforcing plate 220 has a notch 223 in the figure; wherein, the notch 223 can be located at the corner of the end line of the first reinforcing plate 220, or the notch 223 can be located at the middle of the end line of the first reinforcing plate 220, and this embodiment does not limit this. In addition, the second reinforcing plate 230 has an extension section 233 at one end facing the first reinforcing section 221, for example, the left end of the second reinforcing plate 230 has an extension section 233 in the figure, and the extension section 233 extends into the notch 223. It can be understood that the first reinforcing plate 220 and the second reinforcing plate 230 are staggered by the notch 223 and the extension section 233.

[0077] In this embodiment, the second reinforcing plate 230 has an extension section 233 at one end facing the first reinforcing section 221. The extension section 233 extends into the notch 223 of the first reinforcing plate 220, which is beneficial to improve the structural strength of the circuit board extension strip 212 in different directions. For example, it can improve the bending resistance of the circuit board extension strip 212 in the Y-axis direction and the bending resistance of the circuit board extension strip 212 in the Z-axis direction, thereby enabling the circuit board extension strip 212 to connect more and heavier electronic devices.

[0078] In some implementations, refer to Figure 6 , Figure 7 and Figure 8 The second reinforcing plate 230 also includes a body segment 234. The extension segment 233 and the body segment 234 are arranged along the extension direction of the circuit board extension strip 212, for example, along the X-axis direction in the figure. The width direction of the extension segment 233 and the width direction of the body segment 234 are perpendicular to the extension direction of the circuit board extension strip 212, for example, the width direction of the extension segment 233 and the width direction of the body segment 234 are respectively set along the Y-axis direction in the figure, and the extension direction of the circuit board extension strip 212 is set along the X-axis direction. The width of the body segment 234 is greater than the width of the extension segment 233, which can be understood as the body segment 234 being relatively wider.

[0079] In this embodiment, the width of the body segment 234 is greater than the width of the extension segment 233, which is beneficial to improve the structural strength of the circuit board extension strip 212 in different directions through the body segment 234 and the extension segment 233. For example, it can improve the bending resistance of the circuit board extension strip 212 in the Y-axis direction and the bending resistance of the circuit board extension strip 212 in the Z-axis direction, thereby making it easier to connect more and heavier electronic devices to the circuit board extension strip 212.

[0080] In some implementations, refer to Figure 6 , Figure 7 and Figure 8 The first conductive terminal 241 and the second conductive terminal 242 are arranged along the extension direction of the circuit board extension strip 212, for example, along the X-axis direction in the figure; the first conductive terminal 241 is electrically connected to the first reinforcing plate 220, for example, by welding or abutting; the second conductive terminal 242 is electrically connected to the body segment 234, for example, by welding or abutting; see reference Figure 6 Along the extension direction of the circuit board extension strip 212, for example along the X-axis direction in the figure, the first conductive terminal 241, the notch 223, the extension section 233 and the body section 234 are arranged in sequence.

[0081] In this embodiment, the first conductive terminal 241, the notch 223, the extension section 233, and the body section 234 are arranged sequentially along the extension direction of the circuit board extension strip 212. This is beneficial to increase the distance between the first conductive terminal 241 and the second conductive terminal 242 in the extension direction of the circuit board extension strip 212. This allows for both structural strength enhancement through the body section 234 and the extension section 233, and also provides a larger connection space for the first conductive terminal 241 and the second conductive terminal 242 at a position far from the notch 223 and the extension section 233, such as providing a larger welding space.

[0082] In some embodiments, the width of the circuit board extension strip 212 is less than or equal to 2.5 mm, which makes the circuit board extension strip 212 narrower, thus allowing the circuit board assembly 200 to be used in narrower spaces and improving the applicability of the circuit board assembly 200. Furthermore, the width of the circuit board extension strip 212 is less than or equal to 2 mm, which makes the circuit board extension strip 212 narrower, further allowing the circuit board assembly 200 to be used in narrower spaces and improving the applicability of the circuit board assembly 200.

[0083] In some implementations, refer to Figure 3 or Figure 6The electronic device includes a device body and a connecting circuit board 243, wherein the connecting circuit board can be configured as a flexible circuit board or a printed circuit board; one end of the connecting circuit board 243 is connected to the device body, and the other end of the connecting circuit board 243 is provided with a first conductive terminal 241 and a second conductive terminal 242. For example, the conductive layer of the connecting circuit board 243 can be fixedly connected to the first conductive terminal 241 and the second conductive terminal 242 respectively, for example, by welding. The first conductive terminal 241 and the second conductive terminal 242 are respectively disposed between the printed circuit board 210 and the connecting circuit board 243. For example, in the Z-axis direction of the figure, the connecting circuit board 243 and the printed circuit board 210 are respectively located on the upper and lower sides, while the first conductive terminal 241 and the second conductive terminal 242 are located in the middle position. The bracket 251 included in the circuit board assembly 200 can be configured to be fixedly connected to the printed circuit board 210. This fixed connection includes direct connection and indirect connection through other components. Some brackets 251 are disposed on the side of the connecting circuit board 243 facing away from the printed circuit board 210. For example, some brackets 251 are disposed on the upper side of the connecting circuit board 243 in the figure. The brackets 251 are fixedly connected to the connecting circuit board 243.

[0084] In this embodiment, the first conductive terminal 241 and the second conductive terminal 242 are respectively disposed between the printed circuit board 210 and the connecting circuit board 243 of the electronic device, which is beneficial to improving the space utilization of the circuit board assembly 200; a portion of the bracket 251 is disposed on the side of the connecting circuit board 243 facing away from the printed circuit board 210, and the bracket 251 is fixedly connected to the connecting circuit board 243, which is beneficial to improving the connection stability of the electronic device.

[0085] In some implementations, refer to Figure 3 or Figure 6 The circuit board assembly 200 also includes an abutment plate 252, which can be made of an adhesive material. This means the abutment plate 252 can be an adhesive plate, such as one with adhesive backing. Alternatively, the abutment plate 252 can be made of plastic or metal; for example, it can be a steel plate. This embodiment does not limit this. The abutment plate 252 is disposed between the connecting circuit board 243 and a portion of the support 251, as shown in the figure, where the connecting circuit board 243, the abutment plate 252, and the portion of the support 251 are arranged sequentially. One side of the abutment plate 252 is fixedly connected to the connecting circuit board 243, and the other side is fixedly connected to the support 251, including by methods such as adhesive bonding or abutment.

[0086] In this embodiment, one side of the abutment plate 252 is fixedly connected to the connecting circuit board 243, and the other side of the abutment plate 252 is fixedly connected to the bracket 251, which helps to further improve the connection stability of electronic devices.

[0087] In some implementations, refer to Figure 3 or Figure 6 At least one of the first conductive terminal 241 and the second conductive terminal 242 includes a compression spring 244. This means that either the first conductive terminal 241 or the second conductive terminal 242 is provided with a compression spring 244, or both the first conductive terminal 241 and the second conductive terminal 242 are provided with compression springs 244. The compression spring 244 can be understood as a spring in a compressed state. The compression spring 244 abuts against the first reinforcing plate 220 or the second reinforcing plate 230. The compression spring 244 is used to move the printed circuit board 210 and the connecting circuit board 243 away from each other. It can be understood that the compression spring 244 has a tendency to move the printed circuit board 210 and the connecting circuit board 243 away from each other, but this tendency is limited by the support 251 and the printed circuit board 210.

[0088] In this embodiment, the circuit board assembly 200 can improve the connection stability of the electrical connection position by means of the compression spring 244 used to keep the printed circuit board 210 and the connecting circuit board 243 away from each other. It can be understood that the connection between the printed circuit board 210 and the compression spring 244, and the connection between the connecting circuit board 243 and the compression spring 244 are relatively difficult to loosen. In addition, the compression spring 244 can be provided with greater support strength by means of the first reinforcing plate 220, the second reinforcing plate 230 and the bracket 251.
