[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] To facilitate the assembly and disassembly of circuit boards in electronic devices, embodiments of this application provide a circuit board assembly and an electronic device, which will be described below in conjunction with the accompanying drawings.

[0027] For example, please refer to Figure 1 As shown, Figure 1 This is an isometric structural diagram of a circuit board assembly provided in an embodiment of this application. The circuit board assembly 100 in this embodiment includes a circuit board 110 and a mounting base 120.

[0028] Circuit board 110 is a core component in electronic devices, enabling modular functional support to realize the core functions of the electronic device. Circuit board 110 has a top surface and a bottom surface arranged opposite each other. The top surface can be understood as the surface where electronic components, such as resistors and chips, are located; the bottom surface can be understood as the back surface of the surface where electronic components are located, and typically has solder joints or connecting lines. In some embodiments, the finished circuit board 110 structure can also encapsulate the back surface with solder joints or connecting lines to obtain a bottom surface with a flat surface, thereby reducing the impact on other components in the electronic device and facilitating the installation of other components. It should be noted that the top surface and bottom surface are defined in this application embodiment for ease of explanation, but should not be construed as the circuit board 110 only having a top surface and a bottom surface, i.e., it should not be construed as a limitation on the circuit board 110.

[0029] The mounting base 120 includes a base 121, a first elastic element 122, and a second elastic element 123. The first elastic element 122 and the second elastic element 123 are fixedly connected to the base 121, and both the first elastic element 122 and the second elastic element 123 are elastic, such as by using elastic plastic. This reduces the overall weight of the circuit board assembly 100 while ensuring sufficient force resistance. The first elastic element 122 and the second elastic element 123 work together to install and remove the circuit board 110.

[0030] For example, the circuit board assembly 100 has an installed state and a disassembled state.

[0031] The installation state can be understood as the state after the circuit board 110 and the mounting base 120 are assembled together; the installation state can also be called the assembly state. In the installation state, the circuit board assembly 100 can be used to realize the functions of the electronic device.

[0032] In the installed state, the bottom surface of the circuit board 110 is attached to the base 121. The first elastic member 122 cooperates with the base 121 to snap the circuit board 110 in place, thus securing the circuit board 110 securely. Furthermore, the second elastic member 123 abuts against the circuit board 110 and is under pressure. It should be noted that the pressure on the second elastic member 123 is due to the cooperation between the first elastic member 122 and the base 121 pressing the circuit board 110 against the base 121. Due to the positional relationship between the second elastic member 123 and the base 121, the second elastic member 123 is compressed by the circuit board 110 and is thus under pressure.

[0033] The disassembly state can be understood as the state in which the circuit board 110 and the mounting base 120 are about to separate. In this state, the user can remove the circuit board 110 by hand, thereby achieving complete separation of the circuit board 110 and the mounting base 120.

[0034] In the disassembled state, the first elastic element 122 is under pressure under external force, meaning it can move from its initial position to the target position range and change from being engaged with the circuit board 110 in the installed state to being released from it. The second elastic element 123 resets under its own elastic force and pushes the circuit board 110 away from the base 121. When the external force is removed, if the user has not removed the circuit board 110 beforehand, the circuit board 110 will rest on the first elastic element 122.

[0035] It should be noted that, in the disassembled state, although one end of the circuit board 110 is released by the first elastic member 122, the other end of the circuit board 110 is still restricted by the base 121. Therefore, the second elastic member 123 pushing out the circuit board 110 will not cause the circuit board 110 to pop out of the base 121, but will move the circuit board 110 to a position where it is not restricted by the first elastic member 122. At this time, the external force can be removed. After the external force is removed, the circuit board 110 will rest on the first elastic member 122, which can also be considered as the disassembled state.

[0036] In other words, the disassembly state can include a first stage state where an external force acts on the first elastic member 122, moving it from its initial position to a target position range. The disassembly state can further include a second stage state where, after the external force is removed, the first elastic member 122 returns to its original position and the circuit board 110 rests on the outside of the first elastic member 122. Considering that the user can choose when to remove the circuit board 110, the disassembly state is defined as both the first stage state and the second stage state. One possible time to remove the circuit board 110 is when an external force acts on the first elastic member 122, moving it from its initial position to the target position range; this disassembly state is considered the first stage state. Another possible time to remove the circuit board 110 is when, in the first stage state, the external force is removed, the first elastic member 122 returns to its initial position, and the circuit board 110 rests on the first elastic member 122; the circuit board 110 can then be removed at any time thereafter; this disassembly state is considered a combination of the first and second stage states.

[0037] Understandable Figure 1 The diagram shown is a structural schematic of the disassembled state of the circuit board assembly 100. This embodiment of the application uses the structural schematic of the disassembled state as an example for illustration, and should not be construed as a limitation on the structure of the circuit board assembly 100.

[0038] In the circuit board assembly 100 provided in this application embodiment, the circuit board 110 is fixed by a mounting base 120. The mounting base 120 is provided with a first elastic element 122 and a second elastic element 123. The user only needs to apply force to the first elastic element 122 by hand, and with the cooperation of the second elastic element 123, the circuit board 110 can be installed and removed. On the one hand, the circuit board 110 can be securely installed, and on the other hand, the circuit board 110 can be quickly removed without the aid of tools, which improves the convenience of installing and removing the circuit board 110.

[0039] For example, please refer to Figure 2 As shown, Figure 2 This is another isometric structural schematic diagram of the circuit board assembly provided in the embodiments of this application. Figure 2 The circuit board assembly 100 shown is a schematic diagram of its disassembled state, used as an example for illustration and should not be construed as a limitation on the circuit board assembly 100. The base 121 includes a first sub-part 1211, a second sub-part 1212, and a third sub-part 1213 connected in sequence. The first sub-part 1211 and the second sub-part 1212 are bent together, and the third sub-part 1213 is bent together with the second sub-part 1212. In the installed state, the bottom surface of the circuit board 110 is in contact with the second sub-part 1212. The first elastic member 122 is fixedly connected to the first sub-part 1211, and the second elastic member 123 is fixedly connected to the second sub-part 1212.

[0040] It is understood that the second sub-part 1212 is a component that supports the circuit board 110, and the first sub-part 1211 and the third sub-part 1213 are used to support the second sub-part 1212 and to limit the second sub-part 1212 in a set position so as to facilitate the installation and removal of the circuit board 110.

[0041] The structures of the first sub-part 1211, the second sub-part 1212, and the third sub-part 1213 cooperate with the structures of the first elastic member 122 and the second elastic member 123 to install the circuit board 110. The arrangement of the first elastic member 122 and the second elastic member 123 makes it easy to remove the circuit board 110.

[0042] For example, please refer to Figure 1 and Figure 2 And see Figures 3 to 5 As shown, Figure 3 for Figure 1 The top view of the circuit board assembly shown. Figure 4 for Figure 1 The diagram shows a bottom view of the circuit board assembly. Figure 5 for Figure 1 The front view of the circuit board assembly shown.

[0043] The first sub-part 1211 includes a first top wall 1211a and a first bottom wall 1211b. The first sub-part 1211 has a groove 1211c, and the first bottom wall 1211b is part of the groove 1211c, and the first bottom wall 1211b is disposed opposite to the first top wall 1211a. The purpose of the groove 1211c is to accommodate the first elastic member 122. Therefore, the groove 1211c can be surrounded by the first bottom wall 1211b and two side walls connected to the first bottom wall 1211b and disposed opposite to each other, and the two side walls are connected to the first top wall 1211a. Thus, the first top wall 1211a is divided into two parts by the groove 1211c, and the first top wall 1211a is connected to the second sub-part 1212. The first elastic member 122 is connected to the first bottom wall 1211b and extends towards the first top wall 1211a until it protrudes from the first top wall 1211a. The first elastic member 122 extends towards the second sub-part 1212 to facilitate its cooperation with the second sub-part 1212 to clamp the circuit board 110. To avoid interference between the second sub-part 1212 and the first elastic member 122, the second sub-part 1212 is provided with a clearance space to accommodate a portion of the first elastic member 122. By providing the groove 1211c on the first sub-part 1211 to accommodate the first elastic member 122, the first elastic member 122 can be placed without occupying additional space, thus improving space utilization.

[0044] In the case of clamping the circuit board 110, if only one end is clamped, it is easy to cause the fixation to be unreliable and it is not easy to fix the circuit board 110.

[0045] Based on this, the mounting base 120 in this embodiment of the application further includes a snap-fit ​​member 124, which is mounted on the third sub-part 1213. For example, the third sub-part 1213 includes a third top wall 1213a, which is arranged parallel to the first top wall 1211a, and the second sub-part 1212 is inclined between the first top wall 1211a and the third top wall 1213a. The inclination angle can be set as needed and is not specifically limited here.

[0046] The snap-fit ​​component 124 is connected to the third top wall 1213a, meaning the snap-fit ​​component 124 protrudes from and is connected to the third top wall 1213a. The snap-fit ​​component 124 can be bent to achieve snap-fit ​​of the circuit board 110. Furthermore, the snap-fit ​​component 124 may include a first sub-snap-fit ​​component 1241 and two second sub-snap-fit ​​components 1242. The first sub-snap-fit ​​component 1241 is disposed between the two second sub-snap-fit ​​components 1242. The first sub-snap-fit ​​component 1241 and the two second sub-snap-fit ​​components 1242 are arranged along the length of the circuit board 110, thereby forming three snap-fit ​​points. These points cooperate with the first elastic member 122 at one snap-fit ​​point on the other end of the circuit board 110 to securely fix the circuit board 110.

[0047] In the installed state, the snap-fit ​​member 124 and the first elastic member 122 clamp and fix the circuit board 110 from the top surface of the circuit board 110 and cooperate with the second sub-part 1212 from the bottom surface of the circuit board 110. In other words, the snap-fit ​​member 124 and the first elastic member 122 cooperate to snap the circuit board 110 into the second sub-part 1212.

[0048] In order to position the circuit board 110, the second sub-part 1212 is provided with a receiving groove. The second sub-part 1212 can be sunk out of the receiving groove, or a rib can be provided on the second sub-part 1212 to form the receiving groove. The figure shows the rib as an example, but it should not be interpreted as a limitation on the way the receiving groove is set.

[0049] It should be noted that the first sub-part 1211, the second sub-part 1212 and the third sub-part 1213 can be integrally formed during manufacturing, and the snap-fit ​​part 124 can be integrally formed with the third sub-part 1213, thereby facilitating the manufacturing of the mounting base 120.

[0050] The shape and position of the first elastic element 122 and the second elastic element 123 will be described below.

[0051] For example, please refer to Figures 1 to 5 And see Figure 6 and Figure 7 As shown, Figure 6 for Figure 1 The rear view of the circuit board assembly shown. Figure 7 for Figure 3 The diagram shows a cross-sectional view of the circuit board assembly along line AA. The first elastic member 122 includes an elastic plate 1220 and a snap-fit ​​portion 1222. One end of the elastic plate 1220 is connected to the first bottom wall 1211b, and the snap-fit ​​portion 1222 is bent and connected to the other end of the elastic plate 1220. Furthermore, the snap-fit ​​portion 1222 is bent toward the second sub-part 1212. In the installed state, the snap-fit ​​portion 1222 protrudes from the first top wall 1211a toward the second sub-part 1212, thereby facilitating the snap-fit ​​fixation of the circuit board 110.

[0052] The portion of the snap-fit ​​part 1222 facing the second sub-part 1212 may be provided with a stepped structure to fit the edges of the circuit board 110, thereby fixing the circuit board 110.

[0053] For example, the second elastic member 123 may be connected to the third sub-part 1213 and extend to the plane where the second sub-part 1212 is located.

[0054] For example, the second elastic member 123 includes a connecting portion 1230 and an elastic portion 1232. The connecting portion 1230 is bent and connected to the third sub-part 1213, and the elastic portion 1232 is fixedly connected to the connecting portion 1230. The elastic portion 1232 is located on the plane where the second sub-part 1212 is located. The elastic portion 1232 includes a straight section 1232a and a bent section 1232b connected to each other. In the installed state, the straight section 1232a is in contact with the circuit board 110; in the disassembled state, the bent section 1232b abuts against the circuit board 110. It can be understood that the second elastic member 123 is designed to facilitate locking the circuit board 110 in the installed state and to facilitate removing the circuit board 110 in the disassembled state.

[0055] In this circuit board 110, two second elastic members 123 can be provided along its length, and a first elastic member 122 can be located between the two second elastic members 123, so that the circuit board 110 is in a state of balanced force in both the installation and disassembly states, which is beneficial to the stable installation and disassembly of the circuit board 110.

[0056] It should be noted that, in the installed state, the circuit board 110 is fixed by the snap-fit ​​member 124 of the mounting base 120. In conventional methods, a certain gap needs to be reserved between the snap-fit ​​member and the circuit board to prevent the interference fit caused by the machining tolerances of the base and the circuit board from preventing the circuit board from being installed. However, when the circuit board assembly is shaken, the gap between the snap-fit ​​member and the circuit board can cause them to collide and produce abnormal noise. To reduce the generation of abnormal noise in this embodiment, a second elastic member 123 is provided as an elastic pre-compression member. When the first elastic member 122 relaxes the circuit board 110, the second elastic member 123 presses against the circuit board 110 under its own elastic force, ensuring that the circuit board 110 and the base 121 are always in contact, thereby reducing the occurrence of abnormal noise.

[0057] During the disassembly of circuit board 110, the first elastic element 122 first releases circuit board 110 under the action of external force. Under the action of the elastic force of the second elastic element 123, circuit board 110 is pushed away from the second sub-part 1212, that is, the contact surface between circuit board 110 and base 121. At this time, the upper end of circuit board 110 is separated from the second sub-part 1212, and circuit board 110 can be easily removed from base 121 without tools.

[0058] During the installation of circuit board 110, one end of circuit board 110 is first snapped into the snap-fit ​​member 124. Then, under the action of external force, the first elastic member 122 is pulled away from the initial position so that the other end of circuit board 110 can enter the initial position of the first elastic member 122 and abut against the second elastic member 123. Then, the external force is removed, and the first elastic member 122 returns to the initial position under the action of its own elastic force, pressing the circuit board 110 against the second sub-part 1212 until it fits against the second sub-part 1212. During this process, the second elastic member 123 is gradually compressed, which is the pre-compression process mentioned above.

[0059] In the circuit board assembly 100 provided in this application embodiment, the circuit board 110 is fixed by a mounting base 120. The mounting base 120 is provided with a first elastic element 122 and a second elastic element 123. The user only needs to apply force to the first elastic element 122 by hand, and with the cooperation of the second elastic element 123, the circuit board 110 can be installed and removed. On the one hand, the circuit board 110 can be securely installed, and on the other hand, the circuit board 110 can be quickly removed without the aid of tools, which improves the convenience of installing and removing the circuit board 110.

[0060] In the circuit board assembly 100 of this application embodiment, a pre-pressure method is used so that after the locking force is released, the disassembled component, namely the circuit board 110, is automatically ejected under the pre-pressure. Furthermore, the mounting base 120 of this application embodiment has fewer components and lower requirements for positioning accuracy, which can reduce the problem of internal noise in electronic devices caused by tolerances between components. This improves the operational stability and reliability of the circuit board assembly 100, and enhances the user experience of using the electronic device.

[0061] This application also provides an electronic device, which may be a router, smart speaker, in-vehicle computer, or household appliance such as a refrigerator, washing machine, or air conditioner, etc., and is not specifically limited thereto. The electronic device includes a circuit board assembly, which is described above and will not be repeated here.
