Description

Technical Field

[0001] The present disclosure relates to the technical field of antenna devices, and particularly to an antenna structure and an electronic device. Background Art

[0002] In the existing antenna installation structure, in order to ensure good signal reception simultaneously, the antenna needs to be as close as possible to the outer shell of the product. And to reduce costs, an antenna flexible circuit board is usually used as the antenna of the product. To install the antenna on an electronic device, a through groove is usually provided on the frame of the electronic device, and the antenna flexible circuit board is passed through the through groove. The antenna flexible circuit board is bent so that both ends of the antenna flexible circuit board are respectively arranged on the inner side and the outer side of the frame. A spring piece is arranged on the main board of the electronic device, and the spring piece is in abutting connection with the antenna flexible circuit board on the inner side of the frame. When the spring piece is connected to the antenna flexible circuit board and the main board, the antenna flexible circuit board and the main board approach each other so that the spring piece is pressed, ensuring that the spring piece maintains stable contact with the antenna flexible circuit board and the main board. The spring piece being pressed will apply a force to the antenna flexible circuit board, and the antenna flexible circuit board needs to be attached to the inner side of the frame, so that the frame forms reinforcement for the flexible circuit board, maintaining the stable contact between the spring piece and the antenna flexible circuit board, and preventing the spring piece from piercing the flexible circuit board.

[0034] In order to more clearly understand the above-mentioned objects, features and advantages of the present disclosure, the following will further describe the solutions of the present disclosure. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0036] Refer to Figures 1 to 4As shown in the figure, an embodiment of the present disclosure provides an antenna structure, including an antenna flexible circuit board 1, a spring piece 2, and a housing 3; the housing 3 is provided with a mounting groove 31 penetrating through the housing 3, and the mounting groove 31 includes a first through groove 311 and a second through groove 312 communicating with one end of the first through groove 311; the spring piece 2 includes an abutting portion 22 and a connecting portion 21 connected to the end of the abutting portion 22; the antenna flexible circuit board 1 is attached to the outer side of the housing 3 and covers the mounting groove 31, the connecting portion 21 is connected to the antenna flexible circuit board 1, and the abutting portion 22 is used for connecting to the main board 4; in the first direction, the size of the connecting portion 21 is less than or equal to the size of the first through groove 311, and the size of the abutting portion 22 is greater than the size of the first through groove 311; the abutting portion 22 can pass through the second through groove 312 and be arranged inside the housing 3, and the connecting portion 21 can be arranged in the mounting groove 31. When the connecting portion 21 is in the first through groove 311, the abutting portion 22 can abut against the housing 3 in the areas on both sides of the first through groove 311 along the first direction.

[0037] Specifically, the housing 3 can be selected as a housing structure of a flat plate body, and of course, it can also be selected as a housing structure with a skirt plate provided at the edge of the panel; the mounting groove 31 penetrates through the housing 3 in a direction perpendicular to the surface of the housing 3; as Figure 2 、 Figure 3 and Figure 4 The directions indicated by the arrows in the figure are the first direction a and the second direction b. The width direction of the antenna flexible circuit board 1 can be selected as the first direction a, and the length direction of the antenna flexible circuit board 1 can be selected as the second direction b. The main board 4 is arranged on one side of the housing 3, and the abutting portion 22 of the spring piece 2 is in abutting connection with the main board 4. Therefore, the side of the housing 3 close to the main board 4 is the inner side of the housing 3, and the side of the housing 3 facing away from the main board 4 is the outer side of the housing 3.

[0038] The connecting portion 21 and the abutting portion 22 of the above-mentioned spring piece 2 can be selected to be made of metal, and the connecting portion 21 and the abutting portion 22 can be selected to be connected by welding. Of course, it can also be selected that the connecting portion 21 and the abutting portion 22 are integrally cast; the size of the first through groove 311 in the first direction a is greater than or equal to the size of the connecting portion 21, and the size of the first through groove 311 in the second direction b is greater than or equal to the size of the connecting portion 21, so that the connecting portion 21 can be inserted into the first through groove 311; the size of the second through groove 312 in the first direction a is greater than the size of the connecting portion 21, and the size of the second through groove 312 is greater than or equal to the size of the abutting portion 22. The size of the second through groove 312 in the second direction b is greater than the size of the connecting portion 21, and the size of the second through groove 312 is greater than or equal to the size of the abutting portion 22, so that the connecting portion 21 can be inserted into the second through groove 312, and the abutting portion 22 can pass through the second through groove 312 and be arranged inside the housing 3.

[0039] When the abutting portion 22 passes through the second through slot 312, the connecting portion 21 is within the second through slot 312. The connecting portion 21 can move within the second through slot 312, enabling the connecting portion 21 to move to the connection point between the first through slot 311 and the second through slot 312, so that the connecting portion 21 can enter the first through slot 311 along the second direction b. When the connecting portion 21 enters the first through slot 311, the abutting portion 22 moves with the connecting portion 21 to a position opposite to the first through slot 311. Since the dimension of the abutting portion 22 along the first direction is greater than the dimension of the first through slot 311 along the first direction, the abutting portion 22 can abut against the housing 3 in the regions on both sides of the first through slot 311 along the first direction, transmitting the force generated by the elastic piece 2 to the housing 3, and preventing the force generated when the elastic piece 2 is connected to the main board 4 and the antenna flexible circuit board 1 from piercing the antenna flexible circuit board 1.

[0040] The above-mentioned antenna flexible circuit board 1 is attached to the outside of the housing 3 by bonding. Of course, the antenna flexible circuit board 1 can also be attached to the outside of the housing 3 by means of screws or bolts. The antenna flexible circuit board 1 has a blocking effect on the installation slot 31, preventing liquid from flowing between the outside and the inside of the housing 3 through the installation slot 31, thereby improving the waterproof performance of the housing 3.

[0041] The above-mentioned connecting portion 21 can be selected to include two metal blocks, and the abutting portion 22 includes two metal sheets. One metal sheet is connected to one metal block, and the two metal blocks are spaced apart from each other, and the two metal sheets are spaced apart, so that the two metal sheets are connected to the positive and negative poles of the antenna flexible circuit board 1, and the two metal blocks are connected to the positive and negative poles of the main board 4, enabling the elastic piece 2 to correspondingly connect the positive and negative poles of the main board 4 and the positive and negative poles of the antenna flexible circuit board 1.

[0042] When the antenna structure provided by the embodiment of the present disclosure is specifically used, the abutting portion 22 is passed through the second through slot 312, so that the connecting portion 21 is located in the second through slot 312, thereby enabling the antenna flexible circuit board 1 to be attached to the outside of the housing 3. The antenna flexible circuit board 1 and the elastic piece 2 are moved, so that the connecting portion 21 moves to the connection point between the first through slot 311 and the second through slot 312, and then the connecting portion 21 is moved to enter the first through slot 311. When the connecting portion 21 enters the first through slot 311, the abutting portion 22 moves with the connecting portion 21 to a position opposite to the first through slot 311. The antenna flexible circuit board 1 is connected to the outside of the housing 3, and the abutting portion 22 is connected to the main board 4. At this time, the abutting portion 22 abuts against the housing 3 in the regions on both sides of the first through slot 311 along the first direction, transmitting the force generated by the elastic piece 2 to the housing 3. The main board 4 is electrically connected to the antenna flexible circuit board 1 through the elastic piece 2, enabling the main board 4 to send and receive signals through the antenna flexible circuit board 1.

[0043] The antenna structure provided by the embodiments of the present disclosure includes an antenna flexible circuit board 1, a spring piece 2, and a housing 3; the housing 3 is provided with a mounting groove 31 penetrating through the housing 3, and the mounting groove 31 includes a first through groove 311 and a second through groove 312 that communicate with each other; the spring piece 2 includes an abutting portion 22 and a connecting portion 21 connected to the end of the abutting portion 22; the antenna flexible circuit board 1 is adhesively connected to the outer side of the housing 3 and covers the mounting groove 31, so that liquid cannot move between the outer side and the inner side of the housing 3 through the mounting groove 31, improving the waterproof performance of the antenna structure; the connecting portion 21 is connected to the antenna flexible circuit board 1, and the abutting portion 22 is used to be connected to the main board 4 in the first direction, so that the antenna flexible circuit board 1 is electrically connected to the main board 4 through the spring piece 2; the size of the connecting portion 21 is less than or equal to the size of the first through groove 311, and the size of the abutting portion 22 is greater than the size of the first through groove 311; the abutting portion 22 can pass through the second through groove 312 and be arranged inside the housing 3, the connecting portion 21 can be arranged in the mounting groove 31, the connecting portion 21 can move between the first through groove 311 and the second through groove 312 while the abutting portion 22 moves inside the housing 3, and when the connecting portion 21 is in the first through groove 311, the abutting portion 22 can abut against the areas on both sides of the first through groove 311 along the first direction of the housing 3. Through the cooperation of the spring piece 2 and the mounting groove 31, the acting force of the spring piece 2 is transmitted to the housing 3 to avoid piercing the antenna flexible circuit board 1, and the antenna flexible circuit board 1 is attached to the outer side of the housing 3 without bending, simplifying the installation operation of the antenna structure while improving the waterproof performance of the antenna structure and avoiding the spring piece 2 from piercing the antenna flexible circuit board 1.

[0044] Referring to Figure 2 As shown, in some embodiments, in the first direction, the size of the second through groove 312 is greater than the size of the first through groove 311, and the size of the abutting portion 22 is less than or equal to the size of the second through groove 312; the first through groove 311 extends in the second direction, one end of the first through groove 311 along the second direction communicates with the second through groove 312, the size of the connecting portion 21 along the second direction is less than or equal to the sizes of the first through groove 311 and the second through groove 312 along the second direction, and the size of the abutting portion 22 along the second direction is less than or equal to the size of the second through groove 312 along the second direction; the first direction is perpendicular to the second direction. With such a setting, the sizes of the first through groove 311 and the second through groove 312 in the first direction and the second direction are suitable for accommodating the connecting portion 21, and the size of the second through groove 312 is suitable for the abutting portion 22 to pass through, and the first direction and the second direction are perpendicular, and the first through groove 311 extends in the first direction, simplifying the movement track of the connecting portion 21 from the second through groove 312 to the first through groove 311 and facilitating the movement of the connecting portion 21 between the first through groove 311 and the second through groove 312.

[0045] Specifically, one end of the first through slot 311 can be optionally connected to the middle part of the second through slot 312 along the first direction, so that the installation slot 31 forms a T-shaped slot. Of course, it can also be selected that one end of the first through slot 311 is connected to one end of the second through slot 312 along the first direction, so that the installation slot 31 forms an L-shaped slot.

[0046] The dimensions of the above-mentioned connecting portion 21 in the first direction and the second direction are both smaller than the dimensions of the first through slot 311, that is, the dimension of the connecting portion 21 in the first direction is smaller than the dimension of the first through slot 311 in the first direction, and the dimension of the connecting portion 21 in the second direction is smaller than the dimension of the first through slot 311 in the second direction, so that the connecting portion 21 can be arranged in the first through slot 311; the dimensions of the abutting portion 22 in the first direction and the second direction are both smaller than or equal to the dimensions of the second through slot 312, so that the abutting portion 22 can pass through the second through slot 312 and move from the outside of the housing 3 to the inside of the housing 3.

[0047] The dimension of the above-mentioned second through slot 312 in the first direction is larger than the dimension of the first through slot 311, so that the second through slot 312 can adapt to the dimension of the abutting portion 22. The first through slot 311 extends along the second direction, so that the connecting portion 21 can move to the communication place of the first through slot 311 and the second through slot 312 by moving along the first direction in the second through slot 312, and then the connecting portion 21 can move to the first through slot 311 by moving along the second direction. The first direction and the second direction are perpendicular to each other, which simplifies the movement track of the connecting portion 21 from the second through slot 312 to the first through slot 311 and facilitates the movement of the connecting portion 21 between the first through slot 311 and the second through slot 312.

[0048] Refer to Figure 2 As shown, in some embodiments, the depths of the first through slot 311 and the second through slot 312 are smaller than the dimension of the connecting portion 21 in the direction of the antenna flexible circuit board 1 facing the abutting portion 22. With such a setting, after the abutting portion 22 passes through the second through slot 312, the antenna flexible circuit board 1 can be flush with the outside of the housing 3, avoiding deformation and depression of the antenna flexible circuit board 1 at the installation slot 31 and being easily damaged.

[0049] Specifically, the depth direction of the first through slot 311 and the second through slot 312 is the direction in which the antenna flexible circuit board 1 faces the abutting portion 22. When the size of the connecting portion 21 is equal to the depths of the first through slot 311 and the second through slot 312, the connecting portion 21 is in the first through slot 311 and the second through slot 312. One end of the connecting portion 21 is flush with the outer side surface of the housing 3, and the other end of the connecting portion 21 is flush with the inner side surface of the housing 3, and the abutting portion 22 is in contact with the inner side surface of the housing 3. When the size of the connecting portion 21 is greater than the depths of the first through slot 311 and the second through slot 312, when one end of the connecting portion 21 is flush with the outer side surface of the housing 3, the other end of the connecting portion 21 extends out of the first through slot 311 or the second through slot 312. At this time, there is a gap between the abutting portion 22 and the inner side surface of the housing 3. The difference between the connecting portion 21 and the depths of the first through slot 311 and the second through slot 312 is small, so that the gap between the abutting portion 22 and the inner side surface of the housing 3 is small. When the elastic piece 2 is pressed, its own elastic deformation can make the abutting portion 22 abut against the inner side surface of the housing 3; or the elastic piece 2 can move a small distance to make the abutting portion 22 abut against the inner side surface of the housing 3. The antenna flexible circuit board 1 has a certain deformation ability, and the distance that the elastic piece 2 moves is short and will not pierce the antenna flexible circuit board 1.

[0050] Referring Figure 2 、 Figure 3 and Figure 4 As shown in, in some embodiments, the connecting portion 21 includes a support arm 211 and a welding arm 212. The support arm 211 is connected to the abutting portion 22, and the welding arm 212 is connected to the end of the support arm 211 away from the abutting portion 22. The welding arm 212 extends in the first direction. In the first direction, the size of the welding arm 212 is less than or equal to the size of the first through slot 311. The side of the welding arm 212 away from the support arm 211 is welded to the antenna flexible circuit board 1. With such a setting, the support arm 211 functions to connect the welding arm 212 and the abutting portion 22. The size of the support arm 211 can be smaller than that of the welding arm 212, thereby saving the material of the connecting portion 21. The welding arm 212 can extend in the first direction or the second direction to ensure the contact area between the welding arm 212 and the antenna flexible circuit board 1, so that the welding arm 212 and the antenna flexible circuit board 1 can maintain a stable welded connection.

[0051] Specifically, the support arm 211 can be selected as a straight plate structure. The support arm 211 can be selected to extend along the direction of the antenna flexible circuit board 1 towards the housing 3. The welding arm 212 can be selected to extend along the first direction, and of course, it can also be selected to extend along the second direction. As long as the dimensions of the welding arm 212 and the support arm 211 in the first direction are both smaller than the dimension of the first through slot 311 in the first direction, so that the support arm 211 and the welding arm 212 can be arranged in the first through slot 311 and can move in the first through slot 311; the dimensions of the welding arm 212 and the support arm 211 in the second direction are both smaller than the dimensions of the first through slot 311 and the second through slot 312 in the second direction, so that the support arm 211 and the welding arm 212 can be arranged in the second through slot 312 and the support arm 211 and the welding arm 212 can move in the second through slot 312.

[0052] The above-mentioned support arm 211 and welding arm 212 can be selected to be made of metal. The support arm 211 and the welding arm 212 can be selected to be connected by welding. Of course, it can also be selected that the support arm 211 and the welding arm 212 are of an integrated structure. The antenna flexible circuit board 1 is provided with a metal feed point, and the welding arm 212 is welded to the metal feed point.

[0053] Refer to Figure 2 、 Figure 3 and Figure 4 As shown in, in some embodiments, the abutting portion 22 has elasticity. An abutting head 23 is formed at one end of the abutting portion 22 away from the connecting portion 21. The abutting head 23 is used to abut against the main board 4. With such a setting, the abutting portion 22 is pressed between the inner side of the housing 3 and the main board 4, so that the elastic force of the abutting portion 22 itself can drive the abutting head 23 to move towards the main board 4, and can make the abutting head 23 stably abut against the main board 4, improving the stability of the electrical connection between the antenna flexible circuit board 1 and the main board 4 through the elastic sheet 2.

[0054] Specifically, the abutting portion 22 can be selected as an elastic metal sheet or a metal frame. The abutting head 23 can be selected as a cylindrical structure or a convex structure. The abutting head 23 is used to abut against a set position on the main board 4, so that the abutting head 23 is electrically connected to the main board 4, so that the antenna flexible circuit board 1 is electrically connected to the main board 4. When the abutting head 23 abuts against the main board 4, the abutting portion 22 is pressed between the inner side surface of the housing 3 and the main board 4, so that the elasticity of the abutting portion 22 itself drives the abutting head 23 to closely abut against the main board 4, ensuring a stable electrical connection between the elastic sheet 2 and the main board 4.

[0055] Refer to Figure 4As shown, in some embodiments, the abutting portion 22 includes a bottom plate 221, a top plate 223, and a plurality of side plates 222; the top plate 223 is disposed opposite to the bottom plate 221, the plurality of side plates 222 are connected between the top plate 223 and the bottom plate 221, and the side plates 222 are elastic; the connecting portion 21 is connected to the side of the bottom plate 221 facing away from the top plate 223, and the abutting head 23 is connected to the side of the top plate 223 facing away from the bottom plate 221. With such a setting, when the top plate 223 and the bottom plate 221 approach each other, the side plates 222 undergo elastic deformation and apply an elastic force to the top plate 223 and the bottom plate 221, so that the abutting head 23 can stably abut against the main board 4; the structures of the top plate 223, the bottom plate 221, and the side plates 222 are simple, and the manufacturing cost is low.

[0056] Specifically, the bottom plate 221 and the top plate 223 can both be selected as straight plates, the side plates 222 are connected between the bottom plate 221 and the top plate 223, and when the bottom plate 221 and the top plate 223 approach each other, the side plates 222 are compressed and elastically deformed. It can be selected that the bottom plate 221, the top plate 223, and the side plates 222 are all metal sheets, and it can be selected to bend the two ends of a metal sheet to form the structures of the bottom plate 221, the top plate 223, and the side plates 222. Of course, it can also be selected that the bottom plate 221, the top plate 223, and the side plates 222 are connected to each other by welding. When the elastic sheet 2 abuts against the main board 4, the bottom plate 221 abuts against the inner side surface of the housing 3, so that the elastic force of the side plates 222 is transmitted to the housing 3.

[0057] It can be selected that the number of the side plates 222 is multiple, each side plate 222 is connected between the top plate 223 and the bottom plate 221, and the multiple side plates 222 are arranged at intervals, so that when the top plate 223 and the bottom plate 221 approach each other, the multiple side plates 222 are deformed simultaneously.

[0058] Refer to Figure 4 As shown, in some embodiments, a limiting plate 224 is provided between the top plate 223 and the bottom plate 221. The limiting plate 224 extends along the direction of the top plate 223 facing the bottom plate 221, and the limiting plate 224 is connected to one side edge of the top plate 223 and the bottom plate 221 and abuts against the same side edge of the other. With such a setting, when the top plate 223 moves relative to the bottom plate 221, the limiting plate 224 can guide the moving direction of the top plate 223 or the bottom plate 221, and improve the trajectory stability when the top plate 223 moves relative to the bottom plate 221.

[0059] Specifically, the limiting plate 224 can be selected as a straight plate. The straight plate extends along the direction from the top plate 223 towards the bottom plate 221. It can be selected that the limiting plate 224 is connected to one side edge of the top plate 223 along the first direction and abuts against one side edge of the bottom plate 221 along the first direction. Of course, it can also be selected that the limiting plate 224 is connected to one side edge of the top plate 223 along the second direction and abuts against one side edge of the bottom plate 221 along the second direction. Thus, when the top plate 223 moves relative to the bottom plate 221, the bottom plate 221 fits on the surface of the limiting plate 224 and moves along the extension direction of the limiting plate 224.

[0060] Of course, it can also be selected that the limiting plate 224 is connected to one side edge of the bottom plate 221 along the first direction and abuts against one side edge of the top plate 223 along the first direction. Or it is not limited to that the limiting plate 224 is connected to one side edge of the bottom plate 221 along the second direction and abuts against one side edge of the top plate 223 along the second direction. Thus, when the top plate 223 moves relative to the bottom plate 221, the top plate 223 fits on the surface of the limiting plate 224 and moves along the extension direction of the limiting plate 224.

[0061] The number of the above-mentioned limiting plates 224 can be selected as two. The two limiting plates 224 are arranged oppositely along the second direction, and the two limiting plates 224 respectively abut against the two opposite side edges of the top plate 223 along the second direction, or the two limiting plates 224 respectively abut against the two opposite side edges of the bottom plate 221 along the second direction. The two limiting plates 224 have a better limiting effect on the movement tracks of the top plate 223 and the bottom plate 221 relative to each other, and improve the stability of the relative movement of the top plate 223 and the bottom plate 221 when the elastic sheet 2 is pressed.

[0062] Referring to Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the number of the installation grooves 31 is two, and the number of the elastic sheets 2 is two. The two elastic sheets 2 are arranged in one-to-one correspondence with the two installation grooves 31, so that the two elastic sheets 2 are respectively connected to the antenna flexible circuit board 1 through the two installation grooves 31. With such a setting, the two elastic sheets 2 can respectively correspond to the positive and negative poles of the antenna flexible circuit board 1, which is convenient for the electrical connection between the antenna flexible circuit board 1 and the main board 4.

[0063] Specifically, the number of the installation grooves 31 is two. The two installation grooves 31 can be selected to be arranged at intervals along the first direction. The elastic sheets 2 are arranged at intervals along the first direction. The two elastic sheets 2 are arranged in one-to-one correspondence with the two installation grooves 31, so that the two abutting parts 22 can respectively pass through the two second through grooves 312. Then, when the antenna flexible circuit board 1 moves along the first direction and the second direction, the two elastic sheets 2 can move together with the antenna flexible circuit board 1, and the two connecting parts 21 can respectively enter the two first through grooves 311, so that the two abutting parts 22 can respectively abut against the areas of the housing 3 on both sides of the two first through grooves 311 in the first direction.

[0064] Referring to Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the connecting portion 21 is disposed in the middle of the abutting portion 22 in the first direction, and the first through groove 311 is disposed in the middle of the second through groove 312 in the first direction. With this arrangement, after the abutting portion 22 passes through the second through groove 312, the distance between the connecting portion 21 and the first through groove 311 in the first direction is shortened, facilitating the operation of moving the connecting portion 21 from the second through groove 312 to the first through groove 311.

[0065] Specifically, the connecting portion 21 can be selectively disposed at the central position of the abutting portion 22 in the first direction, and the first through groove 311 can be selectively disposed at the central position of the second through groove 312, so that the first through groove 311 and the second through groove 312 form a T-shaped mounting groove 31. After the abutting portion 22 passes through the second through groove 312, the distance between the connecting portion 21 and the first through groove 311 in the first direction is shortened, enabling the antenna flexible circuit board 1 to move a short distance to move the connecting portion 21 from the second through groove 312 to the first through groove 311.

[0066] An embodiment of the present disclosure further provides an electronic device, including a device body, a main board 4, and the antenna structure as described above; the main board 4 is installed on the device body, the housing 3 is disposed opposite to the main board 4 and connected to the device body, the antenna flexible circuit board 1 is connected to the side of the housing 3 facing away from the main board 4, and the main board 4 abuts against the abutting portion 22.

[0067] Specifically, the electronic device can be selectively a device that requires an antenna such as a mobile phone, a smart watch, and a tablet; the main board 4 is installed on the device body, the housing 3 is disposed opposite to the main board 4, and the antenna flexible circuit board 1 is on the side of the housing 3 facing away from the main board 4, so that the antenna flexible circuit board 1 has better signal transmission quality. The connecting portion 21 is connected to the antenna flexible circuit board 1, and the abutting portion 22 abuts against the main board 4, so that the abutting portion 22 is electrically connected to the main board 4, and thus the antenna flexible circuit board 1 is electrically connected to the main board 4 through the elastic piece 2.

[0068] By connecting the housing 3 to the device body, the antenna flexible circuit board 1 covers the mounting groove 31 of the housing 3, improving the waterproof property of the device body, and the antenna flexible circuit board 1 can be electrically connected to the main board 4 through the elastic piece 2 without bending, facilitating the installation of the antenna flexible circuit board 1 on the outside of the housing 3; the acting force of the elastic piece 2 is transmitted to the housing 3, so that the elastic piece 2 does not pierce the antenna flexible circuit board 1, improving the waterproof property of the electronic device and the operation convenience of assembling the antenna structure in the electronic device.

[0069] When the antenna structure and the electronic device provided by the embodiments of the present disclosure are specifically used, the housing 3 is first connected to the device main body. The connecting portion 21 is welded to the antenna flexible circuit board 1. The abutting portion 22 passes through the second through groove 312, so that the connecting portion 21 is located in the second through groove 312, thereby making the antenna flexible circuit board 1 fit on the outer side of the housing 3. The antenna flexible circuit board 1 is first moved in the first direction, so that the connecting portion 21 moves with the antenna flexible circuit board 1 to the communication position of the first through groove 311 and the second through groove 312. Then, the antenna flexible circuit board 1 is moved in the second direction, so that the connecting portion 21 enters the first through groove 311 in the second direction.

[0070] After the connecting portion 21 enters the first through groove 311, the abutting portion 22 moves with the connecting portion 21 to a position opposite to the first through groove 311. The antenna flexible circuit board 1 is adhesively connected to the outer side of the housing 3, and the abutting portion 22 abuts against the main board 4. At this time, the abutting portion 22 abuts against the areas on both sides of the first through groove 311 of the housing 3 in the first direction. The acting force generated by the elastic piece 2 is transmitted to the housing 3, and the abutting portion 22 maintains a stable abutting connection with the main board 4, so that the antenna flexible circuit board 1 maintains a stable electrical connection with the main board 4 through the elastic piece 2, and the operation of installing the antenna structure on the device main body is completed. The main board 4 is electrically connected to the antenna flexible circuit board 1 through the elastic piece 2, so that the main board 4 can send and receive signals through the antenna flexible circuit board 1.
