[0038] In conjunction with Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown in

[0039] In some embodiments of the present application, an electronic device 100 is proposed. The electronic device 100 includes a housing 110, a frame 120, a main board 130, and an electrical connector 140. The housing 110 is made of a non-metallic material, and an installation cavity 115 is provided inside the housing 110. The frame 120 is connected to the housing 110. The frame 120 is made of a metallic material and is sleeved outside the housing 110. The main board 130 is connected to the housing 110 and is located inside the installation cavity 115. There is a gap between the main board 130 and the frame 120. The electrical connector 140 includes a first connection portion 141, a second connection portion 142, and a third connection portion 143. The first connection portion 141 is electrically connected to the frame 120, the second connection portion 142 is electrically connected to the main board 130, and the third connection portion 143 connects the first connection portion 141 and the second connection portion 142.

[0040] The installation cavity 115 is formed inside the housing 110 by machining. The main board 130 is installed inside the installation cavity 115. The frame 120 is connected to the housing 110. Electrical connection between the frame 120 and the main board 130 is achieved through the electrical connector 140. The frame 120 can be an antenna of the electronic device 100.

[0041] Based on the spacing between the main board 130 and the housing 120, the electrical connector 140 electrically connects the main board 130 and the housing 120. The electrical connector 140 includes a first connection portion 141, a second connection portion 142, and a third connection portion 143. The first connection portion 141 is electrically connected to the housing 120, the second connection portion 142 is electrically connected to the main board 130, and electrical connection between the first connection portion 141 and the second connection portion 142 is achieved through the third connection portion 143, so that the housing 120 can perform the function of an antenna.

[0042] In some embodiments, optionally, the housing 120 includes a middle frame 122 and a mounting portion 121. The middle frame 122 is sleeved on the housing 110, the mounting portion 121 is disposed on a side of the middle frame 122 facing the housing 110, the mounting portion 121 is spaced from the main board, the mounting portion 121 and the housing 110 are stacked, and a first mounting gap is provided between the mounting portion 121 and the housing 110. At least a part of the first connection portion extends into the first mounting gap. Along the stacking direction of the mounting portion 121 and the housing 110 ( Figure 5 the arrow direction at H1), a second mounting gap 152 is provided between the main board 130 and the housing 110, and at least a part of the second connection portion 142 extends into the second mounting gap 152.

[0043] The housing 120 includes a mounting portion 121. The mounting portion 121 is stacked on the surface of the housing 110. When the mounting portion 121 and the housing 110 are stacked, a first mounting gap 151 exists between the mounting portion 121 and the housing 110. In the stacking direction of the mounting portion 121 and the housing 110, a second mounting gap 152 exists between the main board 130 and the housing 110.

[0044] After the electronic device 100 is assembled, at least a part of the first connection portion 141 is located in the first mounting gap 151, the first connection portion 141 is clamped and fixed between the mounting portion 121 and the housing 110, at least a part of the second connection portion 142 is located in the second mounting gap 152, and the second connection portion 142 is clamped and fixed between the main board 130 and the housing 110.

[0045] When the electrical connector 140 is a conductive component between the housing 120 and the main board 130, the first connection portion 141 and the second connection portion 142 in the electrical connector 140 make full use of the mounting gaps in the electronic device 100, and no additional locking structure is required to fix the electrical connector 140. Therefore, it does not occupy the available space on the main board 130 and reduces the layout difficulty of the electronic components on the main board 130.

[0046] Combined Figure 1 、 Figure 2 and Figure 5As shown, in some embodiments, optionally, the electronic device 100 further includes: a battery 160, the battery 160 is connected to the main board 130, the main board 130 is located between the battery 160 and the housing 110, the battery 160 is spaced apart from the frame 120, and the third connecting portion 143 is located between the side portion of the battery 160 and the housing 110.

[0047] The battery 160 is installed in the installation cavity 115, and the battery 160 is stacked on the main board 130. There is a third installation gap 153 between the battery 160 and the housing 110, and the third connecting portion 143 is located in the third installation gap 153. It can be seen that the entire electrical connector 140 makes use of the installation gaps in the electronic device 100. There is no need to process a specific structure for the electrical connector 140 in the electronic device 100, which can not only reduce the processing difficulty of the electronic device 100, but also improve the space utilization rate inside the electronic device 100. The electrical connector 140 will not additionally increase the space of the electronic device 100 in the X, Y, and Z directions, thus will not increase the overall size of the electronic device 100.

[0048] When the battery 160 is spaced apart from the frame 120, there is an interval space between the battery 160 and the frame 120, and the battery 160 is not likely to affect the performance of the frame 120 as an antenna, and the clearance requirement of the frame 120 as an antenna is ensured.

[0049] As Figure 5 shown, in some embodiments, optionally, the electrical connector 140 is a spring piece, the first connecting portion 141 located in the first installation gap 151 is in an elastic deformation state, and the first connecting portion 141 is in contact with the frame 120, and, the second connecting portion 142 located in the second installation gap 152 is in an elastic deformation state, and the second connecting portion 142 is in contact with the main board 130.

[0050] In this embodiment, the electrical connector 140 is a spring piece, and the electrical connector 140 has elasticity. When the electrical connector 140 contacts other components, the electrical connector 140 can generate elastic deformation.

[0051] When the first connecting portion 141 is located in the first installation gap 151, the first connecting portion 141 is in an elastic deformation state, so that the first connecting portion 141 can be closely attached to the frame 120, improving the contact stability between the first connecting portion 141 and the frame 120. Similarly, when the second connecting portion 142 is located in the second installation gap 152, the second connecting portion 142 is in an elastic deformation state, so that the second connecting portion 142 can be closely attached to the main board 130, improving the contact stability between the second connecting portion 142 and the main board 130.

[0052] The first connection part 141 contacts the frame 120 through elastic deformation, and the second connection part 142 contacts the mainboard 130 through elastic deformation. No additional components are required to press the first connection part 141 against the frame 120, and no additional components are required to press the second connection part 142 against the mainboard 130, which saves parts in the electronic device 100 and reduces the difficulty of installing the electrical connector 140. By providing the deformable first connection part 141 and the second connection part 142 at both ends of the electrical connector 140, the stability of the signal transmission of the electrical connector 140 is ensured, and tolerance is provided for the installation of the electrical connector 140.

[0053] Combination Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, optionally, the first connection portion 141 includes a sub-connection portion 1411 and a deformation portion 1412 connected to each other, the sub-connection portion 1411 is connected to the third connection portion 143, and the deformation portion 1412 is located on a side of the sub-connection portion 1411 away from the third connection portion 143, along the width direction of the sub-connection portion 1411 ( Figure 6 The arrow at W2 in the middle points to the direction, there is an angle between the deformation portion 1412 and the sub-connection portion 1411, a first feeding point 144 is provided on the first connection portion 141, the first feeding point 144 is electrically connected to the frame 120, the first feeding point 144 is located at the end where the distance between the deformation portion 1412 and the sub-connection portion 1411 is the largest, and the deformation portion 1412 generates elastic deformation in the stacking direction of the mounting portion 121 and the shell 110.

[0054] There is an angle between the deformation part 1412 and the sub-connection part 1411. Since the electrical connection member 140 is a spring sheet, the deformation part 1412 can be deformed and warped relative to the sub-connection part 1411. When the first connection part 141 is installed between the mounting part 121 and the housing 110, the mounting part 121 presses down the deformation part 1412, so that the raised side of the deformation part 1412 is pressed down and elastically deformed, thereby ensuring stable contact between the first connection part 141 and the mounting part 121.

[0055] The distance between the deformation part 1412 and the sub-connection part 1411 gradually increases. At the position where the distance between the two is the largest, the elastic force of the deformation part 1412 is the largest. The first feeding point 144 is set at the position where the elastic force is the largest on the deformation part 1412, so that the first feeding point 144 can stably contact the mounting part 121 under the elastic action of the deformation part 1412, thereby ensuring stable power feeding between the first connection part 141 and the mounting part 121.

[0056] like Figure 6 As shown, one side of the deformation portion 1412 where the first feeding point 144 is disposed is tilted upward.

[0057] Combination Figure 6 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, in some embodiments, optionally, from the side where the second connection portion 142 connects the third connection portion 143 to the side where the second connection portion 142 is away from the third connection portion 143, the width of the second connection portion 142 ( Figure 9 The arrow at W1 in the middle points to the width direction of the second connecting portion 142), and a second feeding point 145 is provided on the side of the second connecting portion 142 away from the third connecting portion 143. The second feeding point 145 is electrically connected to the mainboard 130, and the second connecting portion 142 generates elastic deformation in the stacking direction of the mounting portion 121 and the shell 110.

[0058] One side of the second connection portion 142 is connected to the third connection portion 143, and the other side of the second connection portion 142 is away from the third connection portion 143. The width of the second connection portion 142 decreases from the one side of the second connection portion 142 to the other side of the second connection portion 142. The smaller the width of the second connection portion 142, the easier it is to bend, so that the other side of the second connection portion 142 can be bent and warped compared to the one side of the second connection portion 142. When the second connection portion 142 is installed between the main board 130 and the housing 110, the main board 130 presses down the second connection portion 142, so that the warped side of the second connection portion 142 generates elastic deformation, thereby ensuring stable contact between the second connection portion 142 and the mounting portion 121.

[0059] A second feeding point 145 is provided on a side where the second connection portion 142 is separated from the third connection portion 143, and the second feeding point 145 contacts the main board 130, thereby realizing electrical connection between the second connection portion 142 and the main board 130. A side of the second connection portion 142 away from the third connection portion 143 will produce a larger deformation amount, and the second feeding point 145 is provided on a side of the second connection portion 142 away from the third connection portion 143, so that the second feeding point 145 can stably contact the main board 130 under the elastic action of the second connection portion 142, thereby ensuring stable power feeding between the second connection portion 142 and the main board 130.

[0060] like Figure 6 As shown, one side of the second connection portion 142 where the second feeding point 145 is disposed is tilted upward.

[0061] exist Figure 9 , Figure 10 , Figure 11 and Figure 12In it, the electrical connector 140 is a double-spring-arm elastic sheet. There are differences in the structural forms of the double-spring-arm elastic sheets. The feeding point positions of the double-spring-arm elastic sheets can be flexibly changed. After defining the fixed positions of the double-spring-arm elastic sheets, the feeding point positions can be adjusted by changing the shapes of the double-spring-arm elastic sheets, which can facilitate the antenna to find the optimal feeding point position, is not limited by the structural wall thickness, has better antenna performance, and enables more flexible component layout on the main board 130.

[0062] Combined with Figure 14 、 Figure 15 、 Figure 16 and Figure 17 As shown, in some embodiments, optionally, a bending portion 146 is provided between the first connecting portion 141 and the third connecting portion 143. The bending portion 146 bends away from the first connecting portion 141 compared with the third connecting portion 143, and the bending portion 146 provides a deformation force for the first connecting portion 141.

[0063] In the above embodiment, the first connecting portion 141 extends along the circumferential direction of the frame 120, resulting in a relatively large size of the electrical connector 140 in the width direction. When the installation space of the electrical connector 140 in the width direction is limited, other forms of electrical connectors 140 need to be adopted.

[0064] In this embodiment, a bending portion 146 is provided between the first connecting portion 141 and the third connecting portion 143. The bending portion 146 bends away from the first connecting portion 141 compared with the third connecting portion 143. When the frame 120 is installed on the housing 110, the installation portion 121 will press down the first connecting portion 141. At this time, the bending portion 146 will deform, and after the bending portion 146 deforms, it will provide an elastic force for the first connecting portion 141, so that the first connecting portion 141 closely adheres to the installation portion 121. By changing the deformation mode of the electrical connection portion, the occupied space of the electrical connector 140 in the width direction can be reduced. In this embodiment, the bending portion 146 utilizes the space between the housing 110 and the battery 160, improving the space utilization rate of the electrical connector 140 inside the electronic device 100.

[0065] As Figure 13 shown, in some embodiments, optionally, the electronic device 100 further includes: an extension portion 171 and a locking member 172. The extension portion 171 is connected to the main board 130, and at least a part of the extension portion 171 extends out of the edge of the main board 130. The locking member 172 locks the extension portion 171 on the housing 110, and the locking member 172 is spaced apart from the electrical connector 140.

[0066] An extension portion 171 extends from the edge of the main board 130, and the locking member 172 locks the extension portion 171 to the housing 110, thereby fixing the main board 130. When installing the main board 130, the locking member 172 does not need to be directly connected to the main board 130. Therefore, there is no need to provide mounting holes 147 on the main board 130 that cooperate with the locking member 172, and the electronic components on the main board 130 do not need to avoid the locking member 172, which is beneficial to improving the space utilization rate on the main board 130 and reducing the layout difficulty of the electronic components on the main board 130.

[0067] In a possible application, the extension portion 171 and the main board 130 are integrally formed structures. The extension portion 171 is only used as a mounting structure, and no electronic components need to be arranged on the extension portion 171. Alternatively, the extension portion 171 and the main board 130 are separate structures, and the extension portion 171 is pressed onto the main board 130. After locking the extension portion 171, the extension portion 171 fixes the main board 130 through pressure.

[0068] Figure 18 The position of the dashed line in the figure is the position where an opening is provided on the main board 130 in the related art. This opening position is used to connect a screw. Obviously, the position of the dashed line occupies the space on the main board 130.

[0069] Such as Figure 5 shown, in some embodiments, optionally, the electronic device 100 further includes: a colloid 180. On the circumferential direction of the frame 120 ( Figure 3 the arrow direction at point C in the figure), between the mounting portion 121 and the housing 110 is hermetically connected by the colloid 180, and the colloid 180 is located on the side of the first connection portion 141 away from the mounting cavity 115.

[0070] A colloid 180 is provided between the mounting portion 121 and the housing 110. The colloid 180 seals between the mounting portion 121 and the housing 110 to prevent external water and dust from entering the interior of the housing 110 through the gap between the mounting portion 121 and the housing 110.

[0071] The colloid 180 is located in the first mounting gap 151. The first mounting gap 151 is used to fill the colloid 180, so that there will be a gap between the mounting portion 121 and the housing 110. The first connection portion 141 utilizes the gap between the mounting portion 121 and the housing 110, so that there is no need to additionally increase the space between the mounting portion 121 and the housing 110 for the first connection portion 141, and there is no need to increase the size of the electronic device 100 due to the first connection portion 141.

[0072] The colloid 180 is located on the side of the first connecting portion 141 away from the installation cavity 115, which is equivalent to the colloid 180 being located on the outer side of the first connecting portion 141. Therefore, in this embodiment, when installed in the sealed space of the electronic device 100, there is no need to provide an additional waterproof structure for the electrical connector 140, thus simplifying the structure of the electronic device 100.

[0073] In a possible application, the frame 120 further includes a middle frame 122. The installation portion 121 is arranged on the inner circle of the middle frame 122, and the installation portion 121 is of an annular structure.

[0074] As Figure 5 shown, in some embodiments, optionally, a laser-engraved surface 123 is provided on the side of the installation portion 121 facing the colloid 180. The colloid 180 is bonded to the laser-engraved surface 123, and the first connecting portion 141 is attached to the laser-engraved surface 123.

[0075] The installation portion 121 and the housing 110 are hermetically connected through the colloid 180. Laser engraving treatment is performed on the side of the installation portion 121 facing the colloid 180, so as to form the processed laser-engraved surface 123 on the installation portion 121. The end face after the laser engraving treatment can increase the bonding reliability of the colloid 180 and ensure the sealing effect and connection effect between the installation portion 121 and the housing 110.

[0076] In this embodiment, the first connecting portion 141 is attached to the laser-engraved surface 123. After the surface of the frame 120 is laser-engraved, impurities and surface oxide layers on the frame 120 are removed, increasing the conductivity of the frame 120, which is beneficial to improving the electrical connection effect between the first connecting portion 141 and the frame 120. The first connecting portion 141 directly reuses the laser-engraved surface 123 on the frame 120, that is, the colloid 180 and the first connecting portion 141 share the laser-engraved surface 123 on the frame 120, and there is no need to perform a separate secondary laser engraving treatment for the first connecting portion 141, reducing the processing difficulty of the electronic device 100.

[0077] Combined Figure 2 and Figure 5 shown, in some embodiments, optionally, the housing 110 includes: an outer shell 111 and a quick-release component installation portion 112. The quick-release component installation portion 112 is located inside the outer shell 111. The first connecting portion 141 is located between the installation portion 121 and the quick-release component installation portion 112. A recessed portion 113 is provided on the side of the quick-release component installation portion 112 facing the installation cavity 115, and the third connecting portion 143 is located in the recessed portion 113.

[0078] A quick-release component mounting portion 112 is installed on the housing 111. When the electronic device 100 is a watch, the watch band can be installed on the quick-release component. The quick-release component is a component used to connect with the watch band, and the quick-release component can be installed within the quick-release component mounting portion 112. The second connecting portion 142 is attached to one side of the quick-release component mounting portion 112 facing the mounting cavity 115. A recessed portion 113 is formed on the quick-release component mounting portion 112, and the third connecting portion 143 is located within the recessed portion 113. Therefore, the third connecting portion 143 does not protrude from the position on the quick-release component mounting portion 112 where the recessed portion 113 is not provided, or the third connecting portion 143 slightly protrudes from the position on the quick-release component mounting portion 112 where the recessed portion 113 is not provided, which can reduce the space occupied by the third connecting portion 143 between the quick-release component mounting portion 112 and the battery 160.

[0079] In a possible application, in this embodiment, the depth of the recessed portion 113 is greater than or equal to the thickness of the third connecting portion 143. Therefore, the third connecting portion 143 does not protrude from the position on the quick-release component mounting portion 112 where the recessed portion 113 is not provided, and there is no need to leave an installation space for the third connecting portion 143 between the quick-release component mounting portion 112 and the battery 160, and there is no need to increase the size of the electronic device 100 due to the third connecting portion 143.

[0080] As Figure 4 shown, in some embodiments, optionally, the number of the electrical connectors 140 is at least two, and the at least two electrical connectors 140 are distributed on both sides of the quick-release component mounting portion 112.

[0081] In this embodiment, the number of the electrical connectors 140 is at least two. For example, when the number of the electrical connectors 140 is two, one electrical connector 140 is used for power feeding, and the other electrical connector 140 is used for grounding. Among them, antenna power feeding means that radio frequency energy is transmitted to the antenna through a transmission line so that the antenna can transmit or receive electromagnetic waves. Antenna grounding is one of the key measures for system safety and performance. The main purpose of grounding is to safely guide static electricity or lightning current into the ground to prevent damage to the device and ensure personal safety. In addition, good grounding can provide an effective reference ground for the antenna system, thereby improving the stability and performance of the system. Distributing the at least two electrical connectors 140 on both sides of the quick-release component mounting portion 112 can avoid excessive concentration of the electrical connectors 140 on one side of the quick-release component mounting portion 112, thereby reducing the layout pressure inside the electronic device 100.

[0082] Combined Figure 2 、 Figure 5 and Figure 6 shown, in some embodiments, optionally, the third connecting portion 143 is provided with a mounting hole 147, and the quick-release component mounting portion 112 is provided with a hot-melt portion 114, and the hot-melt portion 114 passes through the mounting hole 147.

[0083] An installation hole 147 is machined and formed on the third connection part 143, and a hot-melt part 114 is arranged on the quick-release component installation part 112. When installing the electrical connector 140, the hot-melt part 114 is passed through the installation hole 147, and then the hot-melt part 114 is subjected to hot-melt treatment, so as to fix the third connection part 143 on the quick-release component installation part 112, prevent the third connection part 143 from separating from the quick-release component installation part 112, and ensure the installation stability of the electrical connector 140.

[0084] In an embodiment of the present application, a direct-feed antenna design for the frame 120 in an extreme space is provided. By using the non-bottleneck thickness space, through a customized double-spring-arm elastic sheet (electrical connector 140), the frame 120 and the main board 130 are directly connected, and the antenna signal of the frame 120 is directly transferred to the copper-clad area of the main board 130 inside the body of the electronic device 100. Without affecting the X / Y-direction stacking design of the whole machine, the double-spring-arm elastic sheet is fixed on the housing 110 by hot melting, and the connection is realized by using the reserved space in the layout (first, the dispensing space between the battery 160 and the housing 110, second, the gap between the main board 130 and the housing 110). Through the reuse of the laser-engraved surface 123 and the assembly process, a simple structure and a very low-cost elastic sheet transfer form, stable and reliable antenna connection is realized in a very small space.

[0085] In the direct-feed antenna design of the frame 120 in this embodiment, by using the existing avoidance space gap and dispensing space in the layout, the double-spring-arm elastic sheet is placed in the gap for signal transfer. The antenna clearance is ensured by the split plastic housing 110. Deformed spring arms (the first connection part 141 and the second connection part 142) are arranged at both ends of the double-spring-arm elastic sheet for stable signal connection and tolerance.

[0086] By customizing the double-cantilever elastic sheet and using the non-bottleneck Z-direction space, the middle-frame antenna is connected to the main board 130 through the elastic sheet. The elastic sheet uses the side gap between the rear shell and the battery 160 and is fixed through the hot-melt column to achieve stable and reliable connection.

[0087] Between the frame 120 and the housing 110 on one side of the elastic sheet, and between the main board 130 and the housing 110 on the other side, the connection is made in the Z direction by using the existing gap. The overall fixing structure does not exceed the quick-release component installation part 112 with a Y-direction bottleneck and does not affect the X / Y-direction layout of the whole machine. The positions of the electrical connector 140 and the locking part 172 are decoupled. The position of the main board 130 is not occupied by the locking part 172, and the layout of the locking part 172 can be closer to the edge and more flexible.

[0088] The overall structure of the double elastic arm shrapnel presents a "Z" shape. There are deformed elastic arms at both end platforms, one side contacts the frame 120, and the other side contacts the main board 130. A round hole is opened in the middle position of the double elastic arm shrapnel, which cooperates with the hot melt column of the housing 110 to fix the double elastic arm shrapnel.

[0089] Combined Figure 6 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, the included angle between the first connecting portion 141 and the third connecting portion 143 can be adaptively processed and adjusted according to requirements, and the relative positions of the first feeding point 144 and the second feeding point 145 can be set on the same side or different sides of the electrical connector 140.

[0090] The detailed assembly of the electronic device 100 is as follows:

[0091] First, align the opening of the double elastic arm shrapnel with the hot melt column of the housing 110, and assemble them on the side. Fix the double elastic arm shrapnel on the housing 110 through the hot melt process. The second connecting portion 142 on the double elastic arm shrapnel is located between the housing 110 and the main board 130, and the first connecting portion 141 of the double elastic arm shrapnel is located between the housing 110 and the frame 120.

[0092] Second, assemble the main board 130 vertically downward. The main board 130 is provided with a copper leakage area at the position where it cooperates with the double elastic arm shrapnel. When the main board 130 is assembled in place, the second connecting portion 142 contacts the copper leakage area of the main board 130. The main board 130 and the housing 110 are fixed by screws (locking parts 172), and at the same time, the stable connection between the double elastic arm shrapnel and the main board 130 is realized.

[0093] Third, after assembling the internal components such as the battery 160 and the speaker, start assembling the frame 120. The frame 120 and the housing 110 are fixed and waterproofed using glue or double-sided tape. Before assembly, the glue surface / double-sided tape surface needs to be laser engraved to increase the bonding reliability, and at the same time, the conductivity of the frame 120 can be increased. The frame 120 is designed with a lug (mounting portion 121) at the position of the first connecting portion 141 to provide tolerance and ensure the stable contact between the double elastic arm shrapnel and the frame 120. The first connecting portion 141 of the double elastic arm shrapnel is initially located on the mating surface of the housing 110 and the frame 120. After the assembly of the housing 110 and the frame 120 is completed, the stable contact between the first connecting portion 141 and the frame 120 is realized simultaneously.

[0094] The electronic device 100 in this embodiment has the following advantages:

[0095] First, low cost, simple structure and light weight.

[0096] Second, the double elastic arm shrapnel can be blindly assembled, with simple operation. Only the process of hot melt fixing the double elastic arm shrapnel is added, and the processes of other workstations are reused for normal assembly.

[0097] Third, the connection is stable and reliable. The connection of the electrical connector 140 is inside the fuselage, isolating the outside world, with a low failure risk and a longer service life.

[0098] Fourth, it does not occupy the internal layout space. The double elastic arm shrapnel reuses the existing layout space. In the thickness direction, it reuses the dispensing space and the gap between the housing 110 and the main board 130. In the length direction, it is within the quick-release component installation part 112. In the width direction, there is no structure, and no bottleneck points are added in the X, Y, and Z directions.

[0099] Fifth, the antenna has excellent performance, the feed point position is flexible, the clearance is large, and the interference is small.

[0100] Figure 15 The figure shows another form of the double elastic arm shrapnel. When there is a bottleneck in the width direction of the whole machine for the double elastic arm shrapnel, the deformation direction of the double elastic arm shrapnel is changed to achieve direct feeding of the frame 120. When the deformation direction of the double elastic arm shrapnel is changed, the space occupied in the width direction is small. In this structure, the width of the double elastic arm shrapnel is shortened, the occupied space is reduced, and the layout flexibility of the screen components can be increased.

[0101] In a possible application, the electronic device 100 can be a smart watch, a mobile phone, a tablet computer, or other smart wearable devices.
