Description

Technical Field

[0001] This disclosure relates to the field of antenna technology, and more particularly to an antenna assembly and electronic device. Background Technology

[0002] As users' demands for electronic device functions become increasingly diverse, the complexity of antenna and circuit design is also gradually increasing. In the antenna assembly of electronic devices, the antenna and the circuit board need to be connected by electrical connectors. At the same time, due to the miniaturization trend of electronic devices, the components on the circuit board are stacked more densely, and the design area of ​​the circuit board is also reduced. In current related technologies, the electrical connectors are usually placed on the circuit board, and the other end of the electrical connector is connected to the antenna assembly. The electrical connectors occupy a large connection area on the circuit board, which is not conducive to achieving miniaturization and integration of electronic devices. Utility Model Content

[0003] To overcome the problems existing in the related technologies, this disclosure provides an antenna assembly and an electronic device.

[0004] According to a first aspect of this disclosure, an antenna assembly is provided, comprising: The frame antenna includes the first sidewall; An electrical connector is mounted on the first sidewall of the frame antenna; A circuit board is disposed inside the frame antenna.

At the same time, it ensures that there is always a sufficient gap between the main body and the elastic support arm, thereby avoiding interference with the performance of the frame antenna due to excessively small gaps. This is beneficial to improving the performance of the frame antenna and the user experience.

[0013] In this disclosure, a second contact portion protruding from the support portion is provided at the free end of the support portion. The second contact portion is used to contact the elastic arm, thereby reducing contact wear between the support portion and the elastic arm and improving the contact stability and reliability between the support portion and the elastic arm.

[0014] In one possible implementation, the elastic arm includes a first part and a second part, the first part being connected to the main body, the second part being bent relative to the first part toward a side away from the main body, a bending portion being provided between the first part and the second part, the bending portion being abutting and connected to the second contact portion.

[0015] In this disclosure, the elastic support arm includes a first part and a second part. The first part is connected to the main body, and the second part is bent away from the main body relative to the first part. A bent part that abuts and connects with the second contact part is also provided between the first part and the second part, thereby avoiding interference between the support part and the connection between the elastic support arm and the circuit board.

[0016] In one possible implementation, the body is welded to the frame antenna.

[0017] In this disclosure, the main body is welded to the frame antenna, thereby improving the connection reliability between the main body and the frame antenna, reducing the risk of electrical connectors falling off, and improving the stability and reliability of the electrical connection of the antenna assembly.

[0018] In one possible implementation, the main body is provided with a welding area, and the elastic arm has a projection area on the main body, the projection area being offset from the welding area.

[0019] In this disclosure, the welding area of ​​the main body and the projection area of ​​the elastic arm on the main body are staggered, thereby avoiding interference from the elastic arm during welding between the main body and the frame antenna, facilitating welding operations, and thus improving welding efficiency.

[0020] In one possible implementation, the body includes a third sidewall located on the side of the body opposite to the frame antenna; The projection area is located in the middle of the third sidewall, and the welding area is located on both sides of the projection area; or, the projection area is located on one side of the third sidewall, and the welding area is located on the other side of the third sidewall.

[0021] In this disclosure, the side of the main body away from the frame antenna is the third sidewall, the projection area is located in the middle of the third sidewall, and the welding area is located on both sides of the projection area; or the projection area is located on one side of the third sidewall, and the welding area is located on the other side of the third sidewall. By staggering the welding area and the projection area, welding is avoided from being interfered with, welding operation is facilitated, and welding efficiency is improved.

[0023] In this disclosure, the electronic device includes the aforementioned antenna assembly. The frame antenna of the antenna assembly and the circuit board are electrically connected by an electrical connector. The circuit board includes a main board and / or a sub-board. Since the electrical connector is located between the first sidewall of the frame antenna and the second sidewall of the circuit board, it does not need to occupy the connection area on the main board and / or the sub-board, which is beneficial for the stacking of components on the main board and / or the sub-board, thereby reducing the overall space occupied by the antenna assembly and realizing the miniaturization and integration of the electronic device.

[0036] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0037] As user demands for electronic device functionality become increasingly diverse, the complexity of antenna and circuit design is also gradually increasing. In the antenna assembly of electronic devices, the antenna and circuit board require electrical connectors for connection. Simultaneously, due to the miniaturization trend in electronic devices, components on the circuit board are stacked more densely, compressing the board's design area. Current technologies mostly employ surface mount technology to place electrical connectors on the circuit board, with the other end of the connector contacting and electrically connecting to the antenna assembly. These connectors typically use surface mount springs and through-hole springs, which carry a high risk of detachment. Furthermore, these connectors occupy a significant connection area on the circuit board, hindering the miniaturization and integration of electronic devices.

[0038] To address the aforementioned technical problems, this disclosure provides an antenna assembly and an electronic device. The antenna assembly of this disclosure electrically connects a frame antenna and a circuit board via an electrical connector. The electrical connector is disposed between the first sidewall of the frame antenna and the second sidewall of the circuit board. Compared to the conventional connection method of placing the electrical connector on the circuit board, this reduces the risk of the electrical connector detaching. The electrical connector does not need to occupy connection area on the circuit board, thereby reducing the overall space occupied by the antenna assembly and facilitating the miniaturization and integration of the electronic device.

[0039] According to an exemplary embodiment, such as Figures 1-10 As shown, this disclosure provides an antenna assembly including a frame antenna 10, an electrical connector 20, and a circuit board 30. The frame antenna 10 radiates by using the metal frame of the electronic device as part of the antenna. The frame antenna 10 includes a first sidewall 11, which is the inner sidewall of the frame antenna 10, that is, the sidewall of the frame antenna 10 that is away from the outside of the electronic device.

[0040] The circuit board 30 is located inside the frame antenna 10, such as... Figure 3 , Figure 4As shown, the circuit board 30 includes a second sidewall 31, which is the sidewall of the circuit board 30 closest to the frame antenna 10. An electrical connector 20 is mounted on the first sidewall 11 of the frame antenna 10. The second sidewall 31 has an electrical connection area 311. The electrical connector 20 is connected to both the first sidewall 11 of the frame antenna 10 and the electrical connection area 311 of the circuit board 30, so that the frame antenna 10 is electrically connected to the circuit board 30 via the electrical connector 20. The circuit board 30 can be configured as a PCB (Printed Circuit Board), but it is understood that it can also be configured as an FPC (Flexible Printed Circuit). This embodiment of the present disclosure does not impose excessive limitations on this.

[0041] Since the electrical connector 20 is installed between the first sidewall 11 and the second sidewall 31, it utilizes the space on the side of the circuit board 30 for electrical connection, instead of directly soldering the electrical connector 20 onto the circuit board 30 as in related technologies. Therefore, it does not require occupying the area on the circuit board 30, which is conducive to achieving tight wiring on the circuit board 30 and also reduces the overall space occupied by the antenna assembly, thereby improving the space utilization rate inside the electronic device.

[0042] In this embodiment, the plane containing the second sidewall 31 is positioned opposite to the plane containing the first sidewall 11. Specifically, if the plane containing the first sidewall 11 is a first plane and the plane containing the second sidewall 31 is a second plane, then the first plane and the second plane are parallel or approximately parallel. The first sidewall 11 and the second sidewall 31 are spaced apart. The projection of the first sidewall 11 onto the second plane can at least partially coincide with the second sidewall 31, or it can be set so that the projection of the first sidewall 11 onto the second plane is offset from the second sidewall 31. The key is to ensure that the first sidewall 11 and the second sidewall 31 are electrically connected via the electrical connector 20. This embodiment does not impose excessive limitations on this aspect.

[0043] It should be noted here that this disclosure Figure 3 The diagram shows the approximate positional relationship between the frame antenna 10, the electrical connector 20, and the circuit board 30, i.e., the arrangement of the three components. The electrical connector 20 is located between the frame antenna 10 and the circuit board 30. Figure 3 Due to limitations of the drawing software, the elastic part 22 of the electrical connector 20 shown in the figure is inserted into the circuit board 30. However, in the actual assembly state, the connection between the elastic part 22 and the circuit board 30 is not as shown in the figure. Instead, the elastic part 22 is connected to the electrical connection area 311 on the second side wall 31 of the circuit board 30 to achieve a stable and reliable electrical connection between the frame antenna 10 and the circuit board 30.

[0044] In this embodiment, the frame antenna 10 and the circuit board 30 of the antenna assembly are electrically connected by an electrical connector 20. The electrical connector 20 is disposed between the first sidewall 11 of the frame antenna 10 and the second sidewall 31 of the circuit board 30. Compared with the conventional connection method of placing the electrical connector 20 on the circuit board 30, the risk of the electrical connector 20 falling off can be reduced. Furthermore, since the electrical connector 20 does not need to occupy the area of ​​the circuit board 30, it is beneficial for other devices on the circuit board 30 to be stacked in a space-efficient manner, thereby reducing the overall space occupation of the antenna assembly and realizing the miniaturization and integration of electronic devices.

[0045] In some embodiments, the electrical connection region 311 includes a groove 3111 and a contact region 3112 disposed within the groove 3111. For example... Figures 4-5 As shown, the electrical connection area 311 is shaped as a groove 3111 recessed from the edge of the second sidewall 31 toward the center of the circuit board 30. The groove 3111 can be formed by cutting, etching, or other methods, or it can be integrally formed with the circuit board 30. A contact area 3112 is provided at the bottom of the groove 3111. The groove 3111 is used to accommodate the electrical connector 20, at least a portion of which extends into the groove 3111. The contact area 3112 is used to contact the electrical connector 20 to achieve electrical connection. The contact area 3112 can be a gold-plated contact area, a silver-plated contact area, a copper-plated contact area, etc. The processing method of the contact area 3112 can be consistent with the process of the circuit board 30, so that the contact area 3112 can be formed at the same time as the circuit board 30, simplifying the processing steps of the circuit board 30 and improving production efficiency.

[0046] In this embodiment of the present disclosure, the electrical connection area 311 includes a groove 3111 and a contact area 3112. The groove 3111 is used to accommodate the electrical connector 20, and the contact area 3112 is used to electrically connect with the electrical connector 20. The space occupied by the antenna assembly is further reduced by the space stacking of the electrical connector 20 extending at least partially into the groove 3111, which is conducive to realizing the miniaturization design of electronic devices.

[0047] In some embodiments, the electrical connector 20 includes a body 21 and an elastic portion 22. For example... Figures 1-3 as well as Figures 6-10 As shown, the elastic part 22 is connected to the main body 21, and the main body 21 is fixedly disposed on the first side wall 11. The electrical connector 20 has the following characteristics: Figure 1 The unassembled state shown and as Figures 2-3 The assembly state shown indicates that when the electrical connector 20 is in the assembled state, the elastic part 22 and... Figures 4-5The electrical connection area 311 shown abuts against the circuit board 30 to achieve electrical connection between the electrical connector 20 and the circuit board 30. The elastic deformation of the elastic part 22 improves the contact tightness between the electrical connector 20 and the circuit board 30, thereby improving the stability and reliability of the electrical connection.

[0048] In this embodiment of the present disclosure, the electrical connector 20 includes a main body 21 and an elastic part 22 connected to the main body 21. The elastic part 22 abuts against the electrical connection area 311 to realize the electrical connection between the electrical connector 20 and the circuit board 30. The elastic deformation of the elastic part 22 improves the stability and reliability of the electrical connection between the electrical connector 20 and the circuit board 30.

[0049] In some embodiments, the electrical connector 20 includes a spring. For example... Figures 6-10 As shown, the elastic part 22 includes an elastic support arm, and a support part 23 is further provided between the elastic support arm and the main body 21. The support part 23 is a simply supported structure with one end raised. Specifically, one end of the support part 23 is connected to the main body 21, and the other end of the support part 23 is bent relative to the main body 21 toward the elastic support arm. In the assembled state, the support part 23 abuts against the elastic support arm to... Figures 1-3 The frame antenna 10 achieves stable antenna performance. At the same time, since the performance of the frame antenna 10 will be interfered with when the gap between the main body 21 and the elastic part 22 (i.e., the elastic support arm) is too small, the support part 23 is set to abut against the elastic support arm to ensure that there is always a sufficient gap between the main body 21 and the elastic support arm, which is conducive to the stable performance of the frame antenna 10 and thus improves the user's communication experience.

[0050] In this embodiment, by providing a support portion 23 connected to the main body 21 and bent relative to the main body 21 toward the elastic support arm, the support portion 23 abuts against the elastic support arm in the assembled state, so that the frame antenna 10 can achieve stable antenna performance. At the same time, it ensures that there is always a sufficient gap between the main body 21 and the elastic support arm, thereby avoiding interference with the performance of the frame antenna 10 due to the small gap, which is beneficial to improving the performance of the frame antenna 10 and the user's experience.

[0051] In one example, the free end of the elastic support arm (i.e., the elastic part 22) is provided with a first contact part 2201, which protrudes from the elastic support arm. The first contact part 2201 is used to contact the second sidewall 31 of the circuit board 30, improving the contact effect between the electrical connector 20 and the circuit board 30. Furthermore, due to the small contact area, it can also reduce contact wear of the elastic support arm, thereby improving the stability and reliability of the electrical connection. The first contact part 2201 can be a dot convex hull, a line convex hull, or other shapes; this embodiment does not impose any special limitations on the specific shape of the first contact part 2201.

[0052] In this embodiment, a first contact portion 2201 protruding from the elastic arm is provided at the free end of the elastic arm, and the first contact portion 2201 contacts and electrically connects with the second sidewall 31 of the circuit board 30, thereby improving the stability and reliability of the electrical connection between the electrical connector 20 and the circuit board 30.

[0053] In some embodiments, the free end of the support portion 23 is provided with a second contact portion (not shown in the figure). For example... Figures 6-10 As shown, the second contact portion protrudes from the support portion 23 and is used to contact the elastic support arm. Because the contact area of ​​the second contact portion is small, it can reduce contact wear between the support portion 23 and the elastic support arm, improving the contact stability and reliability of both. The second contact portion can be a dotted convex hull, a line convex hull, or other shapes. The shape of the second contact portion can be the same as or different from the shape of the first contact portion 2201. This embodiment does not impose any special limitations on the specific shape of the second contact portion.

[0054] In this embodiment of the present disclosure, a second contact portion protruding from the support portion 23 is provided at the free end of the support portion 23. The second contact portion is used to contact the elastic support arm, thereby reducing the contact wear between the support portion 23 and the elastic support arm and improving the contact stability and reliability between the support portion 23 and the elastic support arm.

[0055] In one example, the elastic arm (i.e., the elastic part 22) includes a first part 221 and a second part 222. For example... Figures 6-10 As shown, the first part 221 is connected to the main body 21, and the second part 222 is bent relative to the first part 221 towards the side away from the main body 21. The end of the second part 222 away from the first part 221 is connected to... Figures 1-5 The circuit board 30 is connected, and a bending part 223 is provided between the first part 221 and the second part 222. The bending part 223 abuts and connects with the second contact part.

[0056] In this embodiment of the present disclosure, the elastic support arm includes a first part 221 and a second part 222. The first part 221 is connected to the main body 21, and the second part 222 is bent away from the main body 21 relative to the first part 221. A bent part 223 is also provided between the first part 221 and the second part 222 to abut against and connect with the second contact part, thereby avoiding interference between the support part 23 and the connection between the elastic support arm and the circuit board 30.

[0057] In some embodiments, the main body 21 is welded to the frame antenna 10. For example... Figures 1-3 As shown, the main body 21 and the first sidewall 11 of the frame antenna 10 are connected by welding to improve the connection reliability. The electrical connector 20 can also be provided with, for example, Figure 3The auxiliary mounting part 24 shown is connected to the main body 21. The auxiliary mounting part 24 is used as a handle when welding the electrical connector 20 to the frame antenna 10 to facilitate the welding operation. After welding is completed, the auxiliary mounting part 24 is broken off and removed, and the remaining part is the electrical connector 20 used to realize the electrical connection between the frame antenna 10 and the circuit board 30.

[0058] In this embodiment of the disclosure, the main body 21 is welded to the frame antenna 10, thereby improving the connection reliability between the main body 21 and the frame antenna 10, reducing the risk of the electrical connector 20 falling off, and improving the stability and reliability of the electrical connection of the antenna assembly.

[0059] In one example, such as Figures 6-10 As shown, the main body 21 is provided with a welding area 2101, and the elastic arm (i.e. the elastic part 22) has a projection area 2102 on the main body 21. The projection area 2102 is offset from the welding area 2101, thereby avoiding the presence of the elastic arm from interfering with the welding between the main body 21 and the frame antenna 10.

[0060] In this embodiment, the welding area 2101 of the main body 21 and the projection area 2102 of the elastic arm on the main body 21 are staggered, thereby avoiding interference from the elastic arm during welding between the main body 21 and the frame antenna 10, facilitating welding operations and improving welding efficiency.

[0061] In one example, such as Figures 6-10 As shown, the main body 21 includes a third sidewall 211, which is located on the side of the main body 21 facing away from the frame antenna 10. The side of the main body 21 closest to the frame antenna 10 can be welded to the frame antenna 10 by heating and / or pressurizing the third sidewall 211. In one example, as... Figures 6-8 As shown, the projection area 2102 is located in the middle of the third sidewall 211, and the welding areas 2101 are located on both sides of the projection area 2102, so as to... Figure 7 Taking the orientation shown as an example, the projection area 2102 is located in the central area of ​​the third sidewall 211, and the welding area 2101 is located on the left and right sides of the projection area 2102. In another example, such as Figures 9-10 As shown, the projection area 2102 is located on one side of the third sidewall 211, and the welding area 2101 is located on the other side of the third sidewall 211. Figure 10 Taking the orientation shown as an example, the projection area 2102 is located on the right side of the third side wall 211, and the welding area 2101 is located on the left side of the third side wall 211. Of course, it can be understood that the projection area 2102 can also be located on the left side of the third side wall 211, and the welding area 2101 can be located on the right side of the third side wall 211. This embodiment of the present disclosure does not impose too many restrictions on this.

[0062] In this embodiment, the side of the main body 21 away from the frame antenna 10 is the third sidewall 211, the projection area 2102 is located in the middle of the third sidewall 211, and the welding area 2101 is disposed on both sides of the projection area 2102; or the projection area 2102 is located on one side of the third sidewall 211, and the welding area 2101 is located on the other side of the third sidewall 211. By staggering the welding area 2101 and the projection area 2102, welding is avoided from being interfered with, welding operation is facilitated, and welding efficiency is improved.

[0063] According to an exemplary embodiment, such as Figures 1-10 As shown, this disclosure provides an electronic device, such as a mobile terminal, tablet computer, laptop computer, smartwatch, smart bracelet, etc. The electronic device includes the antenna assembly described in the above embodiment. The antenna assembly includes a frame antenna 10, an electrical connector 20, and a circuit board 30. The frame antenna 10 includes a first sidewall 11, and the circuit board 30 includes a second sidewall 31. The electrical connector 20 is mounted on the first sidewall 11 of the frame antenna 10. The second sidewall 31 has an electrical connection area 311. The electrical connector 20 is connected to both the first sidewall 11 of the frame antenna 10 and the electrical connection area 311 of the circuit board 30, so that the frame antenna 10 is electrically connected to the circuit board 30 through the electrical connector 20.

[0064] The circuit board 30 of the antenna assembly includes a main board and / or a sub-board. In electronic devices, the main board typically serves as the basic framework, integrating core components such as the CPU (Central Processing Unit), memory, and storage to achieve data transmission and signal processing. The sub-board typically connects peripheral modules such as cameras and antennas, allowing some modules to be designed independently and connected to the main board, thereby reducing the design complexity and power consumption of the main board. In one example, the electrical connector 20 can be used to connect the frame antenna 10 to the main board of the electronic device. In another example, the electrical connector 20 is used to connect the frame antenna 10 to the sub-board of the electronic device. In yet another example, the electrical connector 20 connects the frame antenna 10 to both the main board and the sub-board of the electronic device. It is understood that those skilled in the art can make the frame antenna 10 electrically connected to the main board and / or sub-board of the electronic device via the electrical connector 20 according to different design requirements, and this disclosure does not impose any special limitations on this.

[0065] In this embodiment of the disclosure, the electronic device includes the antenna assembly described above. The frame antenna 10 and the circuit board 30 of the antenna assembly are electrically connected by an electrical connector 20. The circuit board 30 includes a main board and / or a sub-board. Since the electrical connector 20 is located between the first sidewall 11 of the frame antenna 10 and the second sidewall 31 of the circuit board 30, it does not need to occupy the connection area on the main board and / or the sub-board, which is beneficial for the stacking of devices on the main board and / or the sub-board, thereby reducing the overall space occupied by the antenna assembly and realizing the miniaturization and integration of the electronic device.

[0066] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0067] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
