Description

Technical Field

[0001] The present application relates to the technical field of terminal equipment, and in particular to an electronic device. Background Art

[0002] The reed is a device used to connect the antenna in electronic devices such as mobile phones. For example, the electronic device may include an antenna, an antenna spring and a circuit board, one end of the antenna spring is electrically connected to the circuit board, and the other end of the antenna spring is connected to the antenna through the reed to achieve signal transmission.

[0003] The reed usually extends toward the back cover of the electronic device and is connected to the antenna by spot welding. To meet the spot welding requirements, the height of the reed in the z direction of the electronic device must be at least 0.9 mm. In this case, in order to avoid interference between the reed and the back cover of the electronic device, the z-direction thickness of the electronic device is also difficult to further reduce. Utility Model Content

[0004] The present application provides an electronic device to solve the problem that the z-direction thickness of the electronic device cannot be reduced when avoiding interference between a reed and a rear housing.

[0005] The present application provides an electronic device, including: a reed, a display screen, a circuit board and an antenna. The display screen and the circuit board are arranged relative to each other along a first direction, and the first direction is the thickness direction of the electronic device; the antenna is arranged at the outer edge of the circuit board; the reed is adjacent to the circuit board and the antenna, and the reed includes a first connecting portion and a second connecting portion connected to each other; the first connecting portion extends toward the display screen and is electrically connected to the antenna, and the second connecting portion is electrically connected to the circuit board.

[0006] In the electronic device provided by the embodiment of the present application, the first connection portion of the reed extends toward the display screen and does not occupy the space in the direction of the rear shell of the electronic device. Thus, even if the thickness of the electronic device is further reduced, the reed will not interfere with the rear shell of the electronic device. Therefore, the electronic device provided by the embodiment of the present application is thinner and lighter, which can improve the user experience.

[0007] In some implementations, the first connection portion has a first angle relative to the second connection portion, and the first angle is greater than 45 degrees and less than 135 degrees. In this way, the first connection portion and the second connection portion are formed at an angle to form a reed, so that the reed can connect antennas and circuit boards located at different positions in the electronic device.

[0008] In some implementations, the second connection portion is parallel to the circuit board; the first connection portion is bent relative to the second connection portion toward the display screen and is parallel to the first direction. In this way, the distance between the first connection portion and the rear housing of the electronic device can be increased to avoid interference between the first connection portion and the rear housing when the reed is installed.

[0009] In some implementations, the device further includes: a middle plate; the middle plate is located between the display screen and the circuit board, and the middle plate includes a protrusion; the protrusion is located between the antenna and the circuit board, and includes a support surface facing away from the display screen; and the second connection portion overlaps the support surface. In this way, the protrusion can be used to support the second connection portion of the spring sheet, so as to avoid deformation of the spring sheet caused by the force applied to the second connection portion, thereby affecting other devices in the electronic device.

[0010] In some implementations, the overlap between the second connection portion and the support surface is greater than 50%, so that the reliability of the second connection portion can be improved and the spring leaf can be prevented from being squeezed and deformed.

[0011] In some implementations, the second connection portion is coplanar with the circuit board on the side facing away from the display screen. In this way, the antenna spring can be arranged flatly, so that the antenna spring will not tilt due to the end being tilted, thereby improving the reliability of the antenna spring.

[0012] In some implementations, the device further includes: a middle frame side wall, the middle frame side wall is arranged around the outer edge of the display screen; the antenna is located on the middle frame side wall, the antenna includes a connection surface, the connection surface is arranged opposite to the first connection part, and the connection surface is welded to the first connection part. In this way, the antenna can be connected to the reed.

[0013] In some implementations, along the second direction, the first connection portion includes a welding portion and a supporting portion connected to each other, and the second direction is parallel to the extension direction of the side wall of the middle frame; the welding portion is welded to the antenna; and the supporting portion is connected to the second connection portion. In this way, the welding portion of the spring used for welding to the antenna and the second connection portion used for connecting to the circuit board can be staggered, which can prevent the laser from being blocked by the second connection portion during laser welding, thereby damaging the second connection portion and affecting the subsequent connection between the second connection portion and the antenna spring.

[0014] In some implementations, along the first direction, the height of the support portion is less than the height of the welding portion. The welding portion includes a first welding portion and a second welding portion connected to each other; along the second direction, the first welding portion is connected to the support portion; along the first direction, the second welding portion is connected to the side of the first welding portion away from the display screen, so that the first welding portion and the second welding portion are arranged on both sides of the second connection portion. In this way, along the first direction, the second connection portion is located in the middle of the first connection portion, so that the side view structure of the reed is a T-shaped structure, which can not only ensure the welding area of ​​the welding portion, but also avoid interference between the first connection portion and the back shell of the electronic device.

[0015] In some implementations, the first connection portion further includes a crack stop groove; the crack stop groove is located at the junction of the welding portion and the supporting portion, and the crack stop groove is transitionally connected to the second connection portion. In this way, the crack stop groove can prevent the spring leaf from bending and deforming when subjected to pressure, thereby preventing the spring leaf from tearing at the junction of the welding portion of the first connection portion and the second connection portion, which affects the reliability of the spring leaf.

[0016] In some implementations, the device further includes: a rear shell and an antenna spring; the rear shell is located on the side of the middle frame side wall facing away from the display screen, and the rear shell is connected to the middle frame side wall; the antenna spring is located on the side of the circuit board facing the rear shell, and one end of the antenna spring is electrically connected to the circuit board, and the other end is connected to the second connection portion of the spring. In this way, the spring can be used to realize the electrical connection between the antenna and the antenna spring, and then the signal transmission path between the antenna, the antenna spring and the circuit board can be realized. Through the elastic contact between the antenna spring and the spring, the elastic contact between the antenna spring and the antenna is realized, so as to realize the transmission and reception of radio frequency signals.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be described clearly below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, other embodiments obtained by ordinary technicians in this field without making creative work all belong to the protection scope of the present application.

[0039] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0040] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to the changes in the orientation of the components in the drawings.

[0041] Figure 1 It is a structural diagram of a terminal device.

[0042] like Figure 1 As shown, the terminal device includes a screen 10a, a middle frame 20a and a back cover (not shown in the figure), the screen 10a and the back cover are located on opposite sides of the middle frame 20a, and the screen 10a, the middle frame 20a and the back cover are buckled and connected in sequence to form a whole machine cavity. Among them, the whole machine cavity includes components such as a motherboard, a battery, a speaker assembly and a camera assembly, which are not listed here one by one.

[0043] To facilitate the explanation of the positions of various components in the terminal device, the embodiment of the present application exemplarily establishes a three-dimensional coordinate system based on the terminal device, wherein the x-axis direction is the width direction of the terminal device, the y-axis direction is the length direction of the terminal device, and the z-axis direction is the thickness direction of the terminal device.

[0044] Figure 2 It is a schematic diagram of the internal structure of a terminal device. Figure 2 The structure of the rear cover from the side view is shown, and Figure 2 The structure of the rear cover is not shown.

[0045] like Figure 2 As shown, electronic components such as a main board 40a and a battery area 50a can be arranged on the middle frame 20a. The main board 40a is located in the upper area of ​​the middle frame 20a, and the battery area 50a is located in the lower area of ​​the main board 40a. The battery area 50a is used to place batteries.

[0046] The terminal device is equipped with an antenna unit to transmit and receive radio frequency signals. As user needs increase, the number of antenna units integrated in the terminal device increases, so that the terminal device can have good radio frequency signal transmission and reception functions. Among them, the terminal device usually uses the metal area on the body shell (such as the metal middle frame) as the antenna radiator.

[0047] The antenna part is located on the middle frame part 20a, or the antenna part can be a part of the middle frame part 20a, and the antenna part can be integrally formed with the middle frame part 20a. Multiple antenna parts can be located at different positions of the middle frame part 20a to achieve omnidirectional signal transmission and improve signal transmission quality and efficiency.

[0048] Exemplarily, the top of the middle frame portion 20a may include two antenna portions, which may be located in areas A1 and A2 of the top of the middle frame portion 20a; the side of the middle frame portion 20a may include three antenna portions, which may be located in areas A3, A4 and A5 of the side of the middle frame portion 20a.

[0049] Figure 3 yes Figure 2 The first local structure diagram of the A4 area. Figure 3 A partial structure of the middle frame portion 20 a is shown.

[0050] like Figure 3 As shown, the middle frame portion 20a includes a middle plate portion 21 and a frame portion 22 surrounding the edge of the middle plate portion 21, and the antenna portion 23 is located on the frame portion 22 and exposed from the frame portion 22 toward the terminal device.

[0051] Correspondingly, combined Figure 1 and Figure 3 As shown, a plurality of antenna slots 24 can be provided on the middle frame 20a, and the antenna slots 24 are made of plastic material. The antenna slots 24 are exposed from the outer surface of the middle frame 20a. Figure 1 and Figure 2 As shown, the antennas in the A1 and A2 regions at the top of the middle frame 20a each correspond to an antenna slot 24, and the antennas in the A3, A4 and A5 regions at the side of the middle frame 20a correspond to an antenna slot 24. In this way, the antenna slot 24 can avoid the shielding effect of metal on the radio frequency signal, thereby improving the radio frequency signal strength while ensuring the strength.

[0052] Figure 4 yes Figure 2 The first partial structural diagram of the BB section.

[0053] like Figure 4As shown, the rear cover 30a of the terminal device is bonded to the middle frame portion 20a by adhesive 31. The middle plate portion 21 is adjacent to the screen 10a, and the main board 40a is located on the side of the middle plate portion 21 away from the screen 10a. The frame portion 22 includes an antenna portion 23, and the antenna portion 23 is located on one side of the outer edge of the main board 40a.

[0054] The connection surface of the antenna part 23 is exposed toward the inside of the terminal device, there is a certain distance between the antenna part 23 and the mainboard 40a, and the portion of the middle frame part 20a located between the antenna part 23 and the mainboard 40a is made of plastic material to ensure sufficient antenna clearance, thereby improving the radiation efficiency of the antenna part 23. The antenna clearance means keeping metal away from the antenna body, that is, no metal device is placed around the antenna part 23 for metal shielding.

[0055] Figure 5 yes Figure 2 The second partial structure diagram of the middle BB section.

[0056] like Figure 5 As shown, the main board 40a is provided with a spring piece 70a, which has conductive properties, can resist interference and electromagnetic wave spillover, and has elasticity and shock-absorbing and suppressing functions. The spring piece 70a serves as an antenna feed point, which is used to connect the main board 40a and the antenna part 23, thereby realizing the transmission and reception of radio frequency signals.

[0057] Since there is a certain distance between the antenna part 23 and the main board 40a, and the size of the spring piece 70a is small, there is also a certain distance between the spring piece 70a and the antenna part 23. Therefore, in order to achieve electrical connection between the antenna part 23 and the spring piece 70a, a spot welding spring piece 60a is provided between the antenna part 23 and the main board 40a. Exemplarily, the spot welding spring piece 60a is made of metal.

[0058] Figure 6 yes Figure 2 The second local structure diagram of the A4 area.

[0059] Combination Figure 4 and Figure 6 As shown, the spot welding spring piece 60a includes a first welding piece 611 and a first contact piece 612 connected to each other, the first welding piece 611 is welded to the connection surface of the antenna part 23, and the first contact piece 612 is connected to the middle plate part 21. The first welding piece 611 and the first contact piece 612 are perpendicular to each other and are L-shaped. The extension direction of the first welding piece 611 is parallel to the z-axis, and the extension direction of the first contact piece 612 is parallel to the x-axis.

[0060] One end of the spring piece 70 a is electrically connected to the main board 40 a , and the other end of the spring piece 70 a is elastically in contact with the first contact piece 612 of the spot welding spring piece 60 a . The first welding piece 611 of the spot welding spring piece 60 a is connected to the antenna portion 23 .

[0061] In this way, the spot welding spring piece 60a can be used to realize the electrical connection between the antenna part 23 and the spring piece 70a, and then the signal transmission path between the antenna part 23, the spring piece 70a and the main board 40a can be realized. Through the elastic contact between the spring piece 70a and the spot welding spring piece 60a, the elastic contact between the spring piece 70a and the antenna part 23 is realized, so as to realize the transmission and reception of radio frequency signals.

[0062] The vertical height of the spot welding spring piece 60a in the z direction must be at least 0.9 mm, that is, the width of the contact surface between the first welding piece 611 and the antenna part 23 is at least 0.9 mm, so that the height H of the first welding piece 611 is 611 The thickness is at least 0.9 mm to ensure the welding area required for spot welding, thereby ensuring the reliability of the spot welding of the spring piece 60 a and the antenna portion 23 .

[0063] However, as the terminal device becomes thinner and lighter, the z-direction space of the terminal device is reduced, and the spot welding reed 60a with a certain height may interfere with the back cover 30a of the terminal device, or even make the spot welding reed 60a unable to be installed. In this case, in order to avoid the spot welding reed 60a from interfering with the back cover of the terminal device, it is difficult to further reduce the z-direction thickness of the terminal device.

[0064] Figure 7 It is a schematic diagram of the structure of a spot-welded spring piece 60a.

[0065] like Figure 7 As shown in (a) and (b), in another implementation, the spot welding spring piece 60a includes a second welding piece 621 and a second contact piece 622 connected to each other, and the second welding piece 621 and the second contact piece 622 form an angle, which is an obtuse angle.

[0066] Figure 8 yes Figure 2 The third partial structure diagram of the middle BB section; Fig. 9 yes Figure 2 The fourth partial structure diagram of the middle BB section.

[0067] like Figure 8 and Fig. 9 As shown, the second welding piece 621 is tilted relative to the second contact piece 622, the extension direction of the second welding piece 621 is tilted relative to the z-axis, and the extension direction of the second contact piece 622 is parallel to the x-axis.

[0068] One end of the spring piece 70 a is electrically connected to the main board 40 a , and the other end of the spring piece 70 a is elastically in contact with the second contact piece 622 of the spot welding spring piece 60 a . The second welding piece 621 of the spot welding spring piece 60 a is connected to the antenna portion 23 .

[0069] In this way, the spot welding spring piece 60a can be used to realize the electrical connection between the antenna part 23 and the spring piece 70a, and then the signal transmission path between the antenna part 23, the spring piece 70a and the main board 40a can be realized. Through the elastic contact between the spring piece 70a and the spot welding spring piece 60a, the elastic contact between the spring piece 70a and the antenna part 23 is realized, so as to realize the transmission and reception of radio frequency signals.

[0070] The second welding piece 621 is tilted, which not only ensures that the width of the contact surface between the second welding piece 621 and the antenna part 23 is at least 0.9 mm to ensure the welding area, but also reduces the vertical height of the second welding piece 621 relative to the second contact piece 622. In this way, the overall height of the spot welding spring piece 60a can be reduced, so that the spot welding spring piece 60a will not interfere with the back cover 30a of the terminal device, and the installation of the spot welding spring piece 60a can be achieved, thereby reducing the z-direction thickness of the terminal device.

[0071] However, the second welding piece 621 is tilted, which will cause the adhesive width W between the rear cover 30a and the middle frame 20a to be 31 The reliability of the rear cover 30a and the middle frame 20a is reduced.

[0072] In order to solve the problem that the z-direction thickness of the terminal device cannot be reduced when the spot welding reed 60a and the back cover 30a are prevented from interfering, the embodiment of the present application provides an electronic device, which uses a reed 100 to achieve the connection between the antenna spring 202 and the antenna 211. In this way, the installation of the spot welding reed can be achieved while achieving the lightness and thinness of the electronic device, and the adhesive width of the back cover 30a and the middle frame 20a is not reduced, so as to ensure the reliability of the back cover 30a and the middle frame 20a.

[0073] The electronic device described in the embodiments of the present application includes but is not limited to a mobile phone, a folding screen mobile phone, a notebook computer, a tablet computer, a laptop computer, a personal digital assistant or a wearable device, etc. The following description is made by taking the electronic device as a folding screen mobile phone.

[0074] Fig.10 is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application; Fig.11 It is a rear view of the electronic device provided in the embodiment of the present application.

[0075] like Fig.10 and Fig.11As shown, in some embodiments, the electronic device may include a first body 10, a second body 20, a display screen 30, and a hinge mechanism 40. The first body 10 and the second body 20 are disposed on both sides of the axis direction of the hinge mechanism 40, and the first body 10 and the second body 20 are respectively connected to the hinge mechanism 40, and can be rotated by the hinge mechanism 40 to reduce the angle between the first body 10 and the second body 20 until the electronic device is in a folded state (not shown in the figure); or increase the angle between the first body 10 and the second body 20 until the electronic device is in an unfolded state, such as Fig.10 and Fig.11 Status shown.

[0076] The display screen 30 covers the first body 10, the second body 20 and the hinge mechanism 40, and is connected to the first body 10 and the second body 20 respectively. The rotation of the first body 10 and the second body 20 can drive the display screen 30 to bend or unfold. Exemplarily, the display screen 30 can be a bendable flexible screen, and the display screen 30 has a bending area, so that the display screen 30 can be bent in the bending area as the hinge mechanism 40 rotates. When the electronic device is in the unfolded state, the hinge mechanism 40 is also in the unfolded state. In the unfolded state, the first body 10 and the second body 20 are parallelly distributed on both sides of the hinge mechanism 40, and the display screen 30 is flat on the hinge mechanism 40 in the unfolded state. When the electronic device is in the folded state, the hinge mechanism 40 is also in the folded state. In the folded state, the first body 10 and the second body 20 are relatively distributed on both sides of the hinge mechanism 40, and the hinge mechanism 40 presses the display screen 30 into a water drop shape.

[0077] Depending on the rotation direction of the first body 10 and the second body 20, the flexible screen may be hidden inside the body when the electronic device is in a folded state, or it may be wrapped around the outside of the body. Among them, when the first body 10 and the second body 20 are folded toward the front of the flexible screen, the flexible screen is hidden inside the body when the electronic device is in a folded state, and this electronic device can be called an inner folding screen electronic device, such as an inner folding screen mobile phone; when the first body 10 and the second body 20 are folded toward the back of the flexible screen, the flexible screen is wrapped around the outside of the body when the electronic device is in a folded state, and this electronic device can be called an outer folding screen electronic device, such as an outer folding screen mobile phone.

[0078] To facilitate the explanation of the positions of various components in an electronic device, the embodiment of the present application exemplarily establishes a three-dimensional coordinate system based on the electronic device, wherein the x-axis direction is the width direction of the electronic device, the y-axis direction is the length direction of the electronic device, and the z-axis direction is the thickness direction of the electronic device.

[0079] Taking the second body 20 as an example, the second body 20 includes a middle frame 210 and a rear shell 220. Part of the display screen 30 and the rear shell 220 are located on opposite sides of the middle frame 210 and are connected. The display screen 30, the middle frame 210 and the rear shell 220 form a body cavity of the second body 20. Electronic devices such as circuit boards, camera modules and batteries can be arranged in the body cavity.

[0080] Fig.12 : is a schematic diagram of the structure of the second fuselage 20 provided in an embodiment of the present application. Fig.12 The structure of the second body 20 is shown from the perspective of the rear case 220 , and the structure of the rear case 220 is not shown.

[0081] like Fig.12 As shown, in some embodiments, in the second body 20, electronic components such as a circuit board 201 and a battery compartment 203 may be disposed on the middle frame 210. The circuit board 201 is located in the upper area of ​​the middle frame 210, and the battery compartment 203 is located in the lower area of ​​the circuit board 201, and the battery compartment 203 is used to place batteries.

[0082] The circuit board 201 can be screwed to the middle frame 210 by screws, or can be snapped to the middle frame 210 by buckles. It should be noted that the specific way of fixing the circuit board 201 to the middle frame 210 in the embodiment of the present application is not limited to this, and other ways can also be used, such as a way of fixing by buckles and screws.

[0083] The battery is electrically connected to the circuit board 201 to provide power to the electronic device. The rear shell 220 of the second body 20 can serve as a battery cover for the battery. The rear shell 220 covers the battery to protect the battery and reduce damage to the battery due to collision, fall, etc. of the electronic device.

[0084] As user demands increase, more and more antennas are integrated into electronic devices, so that the electronic devices can have good radio frequency signal receiving and transmitting functions. Among them, electronic devices usually use metal areas (such as metal middle frames) on the body shell as antenna radiators.

[0085] Taking the antenna being arranged in the second body 20 as an example, multiple antennas (not shown in the figure) may be arranged in the second body 20 to realize the transmission and reception of radio frequency signals of the electronic device. The antenna may be located on the middle frame 210, or the antenna may be a part of the middle frame 210, and the antenna may be integrally formed with the middle frame 210. Multiple antennas may be located at different positions of the middle frame 210 to realize omnidirectional signal transmission and improve the quality and efficiency of signal transmission.

[0086] Exemplarily, the top of the middle frame 210 may include two antennas, which may be located in the C1 and C2 regions of the top of the middle frame 210; the side of the middle frame 210 may include three antennas, which may be located in the C3, C4 and C5 regions of the side of the middle frame 210.

[0087] Fig.13 yes Fig.12 The first local structure diagram of the C5 region. Fig.13 A partial structure of the middle frame 210 is shown.

[0088] like Fig.13 As shown, in some embodiments, the middle frame 210 of the electronic device is formed by combining a metal material 2101 and a plastic material 2102. Fig.13 The area with a filling pattern is a metal material 2101, and the area without a filling pattern and is blank is a plastic material 2102.

[0089] The metal material 2101 and the plastic material 2102 are connected to each other to form a carrier substrate, which is the middle frame 210. Exemplarily, the metal material 2101 and the plastic material 2102 can be integrally formed by an injection molding process.

[0090] The plastic position on the side of the middle frame 210 needs to be exposed to form an antenna slot 215, and the antenna slot 215 is made of plastic material 2102. The antenna slot 215 can avoid the shielding effect of metal on the mobile phone radio frequency signal, and improve the mobile phone radio frequency signal strength while ensuring the strength of the mobile phone.

[0091] Fig.14 yes Fig.12 The first partial structural diagram of the DD section.

[0092] like Fig.14 As shown, in some embodiments, the middle frame 210 may include a middle plate 212 and a middle frame side wall 213, and the middle frame side wall 213 is disposed around the outer edge of the middle plate 212 and the outer edge of the display screen 30. The rear shell 220 and the display screen 30 are respectively located on opposite sides of the middle frame side wall 213, and the rear shell 220 and the middle frame side wall 213 are connected by an adhesive layer 221. Fig.13 and Fig.14 The antenna slot 215 is located on the middle frame side wall 213 and is exposed from the middle frame side wall 213 .

[0093] The middle plate 212 is adjacent to the display screen 30, and the circuit board 201 is located on the side of the middle plate 212 away from the display screen 30. The middle plate 212 is adjacent to the display screen 30, and the extension direction of the middle plate 212 is the same as the extension direction of the display screen 30. The circuit board 201 is located on the side of the middle plate 212 away from the display screen 30, and the display screen 30 and the circuit board 201 are arranged opposite to each other along a first direction, which is the thickness direction of the electronic device, and the middle plate 212 is located between the display screen 30 and the circuit board 201.

[0094] The middle frame sidewall 213 includes an antenna 211, and the antenna 211 is located on one side of the outer edge of the circuit board 201. The middle plate 212 can be formed by injection molding of a metal material 2101 and a plastic material 2102, and the middle frame sidewall 213 can also be formed by injection molding of a metal material 2101 and a plastic material 2102.

[0095] The metal material 2101 can realize the local conductive function, and the plastic material 2102 can realize the insulating function. Therefore, in order to ensure the signal transmission requirements, the structure of the middle frame 210 needs to design the specific distribution of the metal material 2101 and the plastic material 2102 according to the requirements. Fig.13 and Fig.14 The portion of the middle frame side wall 213 used to form the antenna 211 is made of a metal material 2101, and the portion of the middle frame side wall 213 located around the antenna 211 is made of a plastic material 2102; the portion of the middle plate 212 adjacent to the antenna 211 is made of a plastic material 2102, and the remaining portion of the middle plate 212 away from the antenna 211 is made of a metal material 2101.

[0096] That is, the area of ​​the middle frame 210 around the antenna 211 is made of plastic material 2102, and the rest of the area is made of metal material 2101. In addition, the metal material 2101 of the middle frame side wall 213 can be integrally formed with the antenna 211, for example, can be stamped using an aluminum-magnesium alloy material.

[0097] The circuit board 201 is laid flat in the electronic device, and the antenna 211 is vertically arranged on the side wall 213 of the middle frame of the electronic device, with a gap between the antenna 211 and the circuit board 201. The setting of the gap cannot be too large, otherwise it will not meet the miniaturization requirements of the electronic device; the gap cannot be too small, otherwise, when the electronic device is impacted, the antenna 211 and the circuit board 201 are prone to collision, and even cause the reed 100 to be over-compressed and plastically deformed. At the same time, the part of the middle plate 212 located between the antenna 211 and the circuit board 201 is made of plastic material to ensure sufficient antenna clearance, thereby improving the radiation efficiency of the antenna 211.

[0098] The electronic device may further include a reed 100 , which is adjacent to the circuit board 201 and the antenna 211 . The reed 100 is located between the circuit board 201 and the antenna 211 to connect the circuit board 201 and the antenna 211 with a certain interval to form a signal transmission path.

[0099] The reed 100 may include a first connection portion 101 and a second connection portion 102 connected to each other; the first connection portion 101 extends toward the display screen 30 and is electrically connected to the antenna 211 , and the second connection portion 102 is electrically connected to the circuit board 201 .

[0100] In this way, while ensuring that there is enough antenna clearance area in the electronic device, the reed 100 can be used to achieve electrical connection between the antenna 211 and the circuit board 201, and then a signal transmission path between the antenna 211 and the circuit board 201 can be realized to achieve the transmission and reception of radio frequency signals.

[0101] In the electronic device provided in the embodiment of the present application, the first connection portion 101 of the reed 100 extends in the direction of the display screen 30, and does not occupy the space in the direction of the rear shell 220 of the electronic device. In this way, even if the z-axis thickness of the electronic device is further reduced, the reed 100 will not interfere with the rear shell 220 of the electronic device. Therefore, the electronic device provided in the embodiment of the present application is thinner and lighter, which can improve the user experience. In addition, the first connection portion 101 is at a certain distance from the rear shell 220, which will not reduce the adhesive width between the rear shell 220 and the middle frame 210, so as to ensure the reliability of the rear shell 220 and the middle frame 210.

[0102] Fig.15 Schematic diagram of the structure of the reed 100 provided in the embodiment of the present application.

[0103] like Fig.15 As shown in (a), in some embodiments, the reed 100 is made of metal and is used to connect the circuit board 201 and the antenna 211 to achieve a signal transmission path.

[0104] For ease of description, the present embodiment defines a first direction, a second direction, and a third direction. The first direction is the thickness (z-axis) direction of the electronic device, the second direction is parallel to the extension direction of the middle frame side wall 213, that is, the second direction is the length (y-axis) direction of the electronic device, and the third direction is the width (x-axis) direction of the electronic device.

[0105] like Fig.15 As shown in (b), the second connection part 102 is partially connected to the first connection part 101. In this way, the reed 100 can ensure the welding area without occupying too much internal space of the electronic device. At the same time, it can also facilitate the welding of the reed 100 and the antenna 211, and the process operation is convenient.

[0106] Along the y-axis direction, the first connection portion 101 may include a connected welding portion 1011 and a supporting portion 1012. The extending direction of the welding portion 1011 is parallel to the extending direction of the supporting portion 1012, and both are parallel to the first direction; the welding portion 1011 and the supporting portion 1012 are coplanar, forming a flat plate structure.

[0107] The welding part 1011 is used to realize welding with the antenna 211, and the supporting part 1012 is connected to the second connecting part 102, and the supporting part 1012 is used to support the second connecting part 102. Among them, the welding can be performed by laser welding. The welding part 1011 and the second connecting part 102 are staggered along the y-axis direction to prevent the laser from being blocked by the second connecting part 102 during laser welding, thereby damaging the surface of the second connecting part 102 and affecting the subsequent connection between the second connecting part 102 and the antenna shrapnel 202.

[0108] Along the z-axis direction, the height H of the support portion 1012 is 1012 Smaller than the height H of the welding portion 1011 1011 , the second connection part 102 can be located along the z-axis in the middle of the first connection part 101. In this way, the welding area of ​​the welding part 1011 can be guaranteed and the internal space occupied by the electronic device can be reduced.

[0109] like Fig.15 As shown in (c), in some embodiments, the first connection portion 101 has a first angle α relative to the second connection portion 102. 1 , the first angle α 1 That is, the support portion 1012 has a first angle α relative to the second connection portion 102. 1 .

[0110] In one implementation, combining Fig.14 and Fig.15 As shown in (c), the first connection portion 101 is bent relative to the second connection portion 102 toward the display screen 30, and the extension direction of the first connection portion 101 is parallel to the first direction; the second connection portion 102 is parallel to the circuit board 201. The extension direction of the first connection portion 101 and the extension direction of the second connection portion 102 have a first angle α 1 ; Among them, the first angle α 1 That is, the support portion 1012 is vertically connected to the second connection portion 102. Correspondingly, the antenna 211 is vertically arranged on the side wall 213 of the middle frame of the electronic device, and the antenna 211 is parallel to the z-axis direction.

[0111] In another implementation, the extension direction of the first connection portion 101 is not parallel to the first direction, so that the first connection portion 101 is inclined relative to the first direction, and the first connection portion 101 and the second connection portion 102 form an acute angle or an obtuse angle. For example, the first angle α 1 The angle is 45 degrees or 135 degrees. Since the first connection portion 101 extends toward the display screen 30, even if the extension direction of the first connection portion 101 is not parallel to the first direction, it will not cause interference between the first connection portion 101 and the rear shell 220. Correspondingly, the antenna 211 is arranged on the side wall 213 of the middle frame of the electronic device in an inclined state, and the antenna 211 is not parallel to the z-axis direction.

[0112] In this way, the state of the antenna 211 is adapted to the connection state of the first connection portion 101 and the second connection portion 102 of the reed 100 , so as to facilitate welding of the antenna 211 and the first connection portion 101 .

[0113] In some embodiments, the welding portion 1011 includes a first welding portion 1011a and a second welding portion 1011b connected to each other; Fig.15 As shown in (b) and (c), along the y-axis direction, the first welding portion 1011a is connected to the supporting portion 1012; Fig.14 and Fig.15 As shown in (c), along the z-axis direction, the second welding portion 1011b is connected to the side of the first welding portion 1011a away from the display screen 30, so that the first welding portion 1011a and the second welding portion 1011b are respectively arranged on both sides of the second connection portion 102.

[0114] The second connection portion 102 is located between the two ends of the first connection portion 101 along the first direction relative to the height of the first connection portion 101. In other words, the second connection portion 102 is located in the middle of the first connection portion 101, so that the side view structure of the reed 100 is a T-shaped structure.

[0115] In this way, along the z-axis direction, the end of the first connection part 101 that is away from the display screen 30 is extended a certain distance toward the rear shell 220 relative to the second connection part 102, which can increase the surface area of ​​the first connection part 101, thereby increasing the welding area between the first connection part 101 and the antenna 211, and ensuring welding reliability. It should be noted that there is still a safe interval between the extended first connection part 101 and the rear shell 220 to avoid interference between the first connection part 101 and the rear shell 220.

[0116] like Fig.15 As shown in (a) and (b), in some embodiments, the first connection portion 101 may further include a crack-stopping groove 103 , and the crack-stopping groove 103 is located at the boundary between the welding portion 1011 and the supporting portion 1012 .

[0117] Fig.15 (b) exemplarily shows that the crack-stopping groove 103 is located in the welding portion 1011 , and the crack-stopping groove 103 is formed by the boundary between the welding portion 1011 and the supporting portion 1012 being recessed into the welding portion 1011 by a certain depth along the z-axis.

[0118] One side edge of the crack stopping groove 103 is transitionally connected to the side of the second connection portion 102 facing the welding portion 1011 , and the other side edge of the crack stopping groove 103 is transitionally connected to the side of the welding portion 1011 facing the second connection portion 102 .

[0119] In this way, the crack-stop groove 103 can prevent the spring leaf 100 from bending and deforming when subjected to pressure, thereby preventing the spring leaf 100 from being torn at the junction of the welding portion 1011 of the first connecting portion 101 and the second connecting portion 102 , thereby affecting the reliability of the spring leaf 100 .

[0120] Fig.16 yes Fig.12 The second partial structural diagram of the middle C5 region; Fig.17 yes Fig.12 Schematic diagram of the third local structure of the middle C5 region.

[0121] Combination Fig.13 , Fig.14 , Fig.16 and Fig.17 As shown, in some embodiments, the antenna 211 includes a connecting surface 2111 , the connecting surface 2111 is disposed opposite to the first connecting portion 101 of the reed 100 , and the connecting surface 2111 is connected to the first connecting portion 101 by welding.

[0122] The middle plate 212 may include a protrusion 214 , where the protrusion 214 is located between the antenna 211 and the circuit board 201 , and the protrusion 214 includes a supporting surface 2141 facing away from the display screen 30 .

[0123] The first connection portion 101 of the reed 100 is used to connect the antenna 211, and the first connection portion 101 extends in the direction of the display screen 30. The second connection portion 102 of the reed 100 extends in the direction of the circuit board 201 and overlaps the support surface 2141 of the protrusion 214. The extension direction of the second connection portion 102 is parallel to the extension direction of the circuit board 201, and on the side away from the display screen 30, the second connection portion 102 is coplanar with the circuit board 201. Exemplarily, the second connection portion 102 can be attached to the protrusion 214 by adhesive to fix the second connection portion 102.

[0124] In this way, the protrusion 214 can be used to support the second connection portion 102 of the reed 100 to prevent the second connection portion 102 from being subjected to force and causing the reed 100 to deform and affect other components in the electronic device.

[0125] In some embodiments, the protrusion 214 can be integrally formed with the middle plate 212. The protrusion 214 can be made of plastic material to play an insulating role. In this way, the spring 100 and the protrusion 214 are not connected to avoid short circuit.

[0126] In some embodiments, the overlap between the second connection portion 102 and the support surface 2141 is greater than 50%. The overlap refers to the ratio of the overlap area between the second connection portion 102 and the support surface 2141 to the total surface area of ​​the second connection portion 102. In this way, the reliability of the second connection portion 102 can be improved, and the spring leaf 100 can be prevented from being squeezed and deformed.

[0127] Fig.18 yes Fig.12 Schematic diagram of the fourth local structure of the middle C5 region; Fig.19 yes Fig.12 The second partial structure diagram of the DD section.

[0128] like Fig.18 and Fig.19 As shown, in some embodiments, the electronic device may further include an antenna shrapnel 202, which has conductive properties, can resist interference and electromagnetic wave spillover, and has elasticity and shock-absorbing and suppressing functions. The antenna shrapnel 202 serves as an antenna feed point, and is used to connect the circuit board 201 and the antenna 211, thereby realizing the transmission and reception of radio frequency signals.

[0129] The antenna spring 202 is located on the side of the circuit board 201 facing the rear housing 220, and the antenna spring 202 is connected across the circuit board 201 and the second connection portion 102 of the spring 100. Since the second connection portion 102 is coplanar with the circuit board 201 on the side away from the display screen 30, the antenna spring 202 can be arranged flatly, so that the antenna spring 202 will not tilt due to the end being tilted, thereby improving the reliability of the antenna spring 202.

[0130] One end of the antenna spring 202 is electrically connected to the circuit board 201 , the other end of the antenna spring 202 is elastically in contact with the second connection portion 102 of the reed 100 , and the first connection portion 101 of the reed 100 is connected to the antenna 211 .

[0131] In this way, the reed 100 can be used to realize the electrical connection between the antenna 211 and the antenna spring 202, and then the signal transmission path of the antenna 211, the antenna spring 202 and the circuit board 201 can be realized. Through the elastic contact between the antenna spring 202 and the reed 100, the elastic contact between the antenna spring 202 and the antenna 211 is realized, so as to realize the transmission and reception of radio frequency signals.

[0132] In the electronic device provided by the embodiment of the present application, the first connection part 101 of the reed 100 extends toward the display screen 30 side, which can increase the distance between the first connection part 101 and the rear shell 220 of the electronic device. The first connection part 101 does not occupy the space in the direction of the rear shell of the electronic device. Even if the thickness of the electronic device is further reduced, the reed 100 and the rear shell 220 will not interfere with each other, thereby ensuring the installation of the reed 100; and the adhesive width between the rear shell 220 and the middle frame 210 can also be ensured to ensure the reliability of the rear shell 220 and the middle frame 210. At the same time, while ensuring that the first connection part 101 does not interfere with the rear shell 220, the first connection part 101 can extend a certain distance toward the rear shell 220 side relative to the second connection part 102 to form a T-shaped structure to ensure the welding area between the first connection part 101 and the antenna 211, so as to ensure the welding area required for spot welding. Therefore, the electronic device provided by the embodiment of the present application is thinner and lighter, which can improve the user experience.

[0133] It should be noted that those skilled in the art will readily come up with other embodiments of the present application after considering the specification and practicing the application disclosed herein. The present application is intended to cover any variations, uses or adaptations of the present application, which follow the general principles of the present application and include common knowledge or customary technical means in the art that are not disclosed in the present application.
