Description

Technical Field

[0001] The present application relates to the technical field of electronic devices, and in particular, to a button assembly, an electronic device, and a manufacturing method of a button bracket. Background Art

[0002] Multiple antennas are usually provided in an electronic device to meet various communication functions of the electronic device, such as Bluetooth, wireless fidelity (WiFi), call, etc. There is an antenna gap between different antennas to reduce the problem of poor coupling between antennas. When the antenna gap is set at the middle position of the side key of the electronic device, the structure needs to meet the requirements of both the assembly strength of the side key and the antenna performance.

[0003] In the prior art, a flexible printed circuit (FPC) bracket made of pure plastic material is usually adopted. The FPC bracket can be arranged on the side of the antenna away from the side key to avoid the problem of poor coupling between two antenna branches. At least part of the FPC bracket can also be connected to the lug of the side key to prevent the side key from detaching from the electronic device. However, the overall strength of the FPC bracket made of pure plastic material is poor, especially the part of the bracket at the position of the side key lug is prone to deformation or even fracture. If a steel sheet is arranged at the antenna gap position to improve the structural strength, it will cause a change in the length of the antenna branch and even change the nature of the antenna, making it difficult to meet the antenna function requirements.

[0054] Figure 1It is a schematic structural diagram of an electronic device 100. The button assembly can be arranged on the side edge of the electronic device 100. For example, it can be arranged on the right side of the electronic device 100. Exemplarily, the button assembly can include a power button 112 and a volume button 111. The power button 112 can be used to turn on and off the screen of the electronic device 100, power off and power on the electronic device 100, etc. The volume button 111 can be used to increase or decrease the volume of audio and video playback of the electronic device 100, and functions such as taking screenshots. The power button 112 can also be called the first button, and the volume button 111 can also be called the second button. Or the power button 112 can be called the second button, and the volume button 111 can be called the first button. The power button 112 and the volume button 111 can be arranged on the same side of the electronic device 100, or they can also be arranged on different sides of the electronic device 100. The structure of the button assembly needs to meet the strength requirements so that the button assembly can withstand multiple presses without problems such as deformation or fracture.

[0055] Multiple antennas are usually also arranged in the electronic device 100 to meet different communication requirements. There are gaps between the multiple antennas to reduce the problem of poor coupling between antennas. When the gap between the antennas is arranged at the button and its nearby positions, the structure needs to meet the requirements of both the button structure strength and the antenna performance at the same time.

[0056] Figure 2 It is a schematic structural diagram of a button assembly in the prior art. The middle frame 110 can be made of a non-metallic material. The first antenna 121 and the second antenna 122 are arranged in the middle frame 110. A plastic bracket 130 is arranged on the side of the first antenna 121 and the second antenna 122 away from the first button 111 and the second button 112. The plastic bracket 130 can also be called a non-metallic bracket. The plastic bracket 130 can be used to support the FPC. For example, the side of the plastic bracket 130 away from the first antenna 121 and the second antenna 122 can include a groove, and the FPC can be arranged in the groove. And, a lug of the first button 111 and a lug of the second button 112 can be connected to the plastic bracket 130 to prevent the first button 111 or the second button 112 from detaching from the electronic device. The plastic bracket 130 scheme can reduce the problem of poor coupling between two antenna branches. However, the overall strength of the plastic bracket 130 is poor. In particular, the part of the plastic bracket 130 at the lug position is prone to fracture or deformation. And arranging a steel sheet at the antenna gap position to improve the structural strength will easily cause changes in the length of the antenna branches and even change the nature of the antenna, making it difficult to meet the antenna function requirements. Therefore, it is necessary to provide a button assembly that can meet both the requirements of antenna performance and the strength requirements of the button structure.

[0057] The following will introduce in detail the structure of the button assembly provided in the embodiments of the present application with reference to the accompanying drawings. First, refer to Figure 3 the exploded view of the button assembly shown in Figure 4 and the cross-sectional view of the button assembly along the xy plane shown in

[0058] The button assembly may include a first button 111 and a second button 112. The first button 111 and the second button 112 may be disposed on the same side of the electronic device, and the first button 111 and the second button 112 may be arranged along a first direction, which may be the length direction of the first button 111 and the second button 112, that is, the y-axis direction shown in the figure. The first button 111 and the second button 112 may include portions disposed outside the middle frame 110 of the electronic device so that users can press the first button 111 and the second button 112. The first button 111 and the second button 112 may also include portions disposed inside the middle frame 110 of the electronic device, which are used to realize the electrical connection between the first button 111 and the second button 112 and the circuit board when the first button 111 and the second button 112 are pressed, thereby realizing different functions of the electronic device.

[0059] Specifically, refer to Figure 5 the button structure shown in Figure 5 where (a) in Figure 5 is the structure of the first button 111, and Figure 5As shown in (a) thereof, the first button 111 may include a first button body 1111. The cross-sectional shape of the first button body 1111 along the yz plane may be, for example, an annular shape or a rectangular shape. The first button 111 may further include first lugs 1113. The number of the first lugs 1113 may be two. For example, it may include first lugs 1113A and 1113B, and they may be respectively disposed at both ends of the first button body 1111. Both ends of the first button body 1111 may refer to both ends of the first button body 1111 along the first direction. The main plane of the first lug 1113 may be parallel to the main plane of the first button body 1111. The main plane of the first button body 1111 may refer to the surface with a larger planar area of the first button body 1111, that is, the yz plane shown in the figure. The main plane of the first button body 1111 may also be referred to as the main plane of the first button 111. Similarly, the main plane of the first lug 1113 may refer to the surface with a larger planar area of the first lug 1113, that is, the yz plane shown in the figure. The first button 111 may further include a first connecting column 1112. The first connecting column 1112 may be disposed between the first lug 1113 and the first button body 1111 for connecting the first lug 1113 and the first button body 1111. When the first button 111 is disposed in the electronic device, at least a part of the first button body 1111 may be located outside the middle frame 110 for a user to press the first button 111, while the first lug 1113 and the first connecting column 1112 may be located inside the middle frame 110.

[0060] As Figure 5 As shown in (b) thereof, similar to the structure of the first button 111, the second button 112 may include a second button body 1121. When the first button 111 is a volume button and the second button 112 is a power button, the dimension of the second button 112 along the y-axis direction may be smaller than the dimension of the first button along the y-axis direction. The second button 112 may include second lugs 1123. The number of the second lugs 1123 may be two. For example, it may include second lugs 1123A and 1123B, and they may be respectively disposed at both ends of the second button body 1121. The second button 112 may further include a second connecting column 1122. The second connecting column 1122 may be disposed between the second lug 1123 and the second button body 1121 for connecting the second lug 1123 and the second button body 1121. When the second button 112 is disposed in the electronic device, at least a part of the second button body 1121 may be located outside the middle frame 110 for a user to press the second button 112, while the second lug 1123 and the second connecting column 1122 may be located inside the middle frame 110.

[0061] Exemplarily, the structure of the middle frame may refer to Figure 6In the structure shown, the middle frame 110 may include a through hole 113. The position of the through hole 113 may correspond to the position of the first button 111. The dimension of the through hole 113 in the y-axis direction may be the same as the dimension of the first button body 1111 in the y-axis direction, and the dimension of the through hole 113 in the z-axis direction may be the same as the dimension of the first button body 1111 in the z-axis direction, so that the first button body 1111 can be at least partially received in the through hole 113. Moreover, when the first button 111 is pressed, the first button body 1111 can be displaced in the second direction in the through hole 113. The second direction may be a direction perpendicular to the main plane of the first button 111, or in other words, a direction perpendicular to the main plane of the first button body 1111. This second direction is the x-axis direction shown in the figure. The middle frame 110 may further include a through hole 114. The position of the through hole 114 may correspond to the position of the second button 112. The dimension of the through hole 114 in the y-axis direction may be the same as the dimension of the second button body 1121 in the y-axis direction, and the dimension of the through hole 114 in the z-axis direction may be the same as the dimension of the second button body 1121 in the z-axis direction, so that the second button body 1121 can be at least partially received in the through hole 114. Moreover, when the second button 112 is pressed, the second button body 1121 can be displaced in the second direction in the through hole 114.

[0062] The button assembly may further include a first antenna 121 and a second antenna 122. The structures of the first antenna 121 and the second antenna 122 can be referred to Figure 7 the schematic diagram of the antenna structure shown. The first antenna 121 and the second antenna 122 may be disposed within the middle frame 110, that is, on a side of the middle frame 110 away from the first button body 1111. There may be a gap 123 between the first antenna 121 and the second antenna 122 in the first direction. The gap 123 may be formed by two ends of the first antenna 121 and the second antenna 122 approaching each other in the first direction, and the gap 123 may be located between the first button 111 and the second button 112. Exemplarily, the dimension of the gap 123 in the first direction may be 0.8 mm to 1.2 mm, that is, the distance between the two ends of the first antenna 121 and the second antenna 122 approaching each other in the first direction may be 0.8 mm to 1.2 mm.

[0063] It should be noted that the first antenna 121 and the second antenna 122 can be disposed within the middle frame 110 or be part of the middle frame 110. That the first antenna 121 and the second antenna 122 are part of the middle frame 110 may mean reusing the structure of the middle frame 110 to implement the antenna function, so as to reduce the volume and weight of the electronic device. The present application does not limit the shapes and structures of the antenna and the middle frame 110. When the first antenna 121 and the second antenna 122 are part of the structure of the middle frame 110, the material of the middle frame 110 can be a metallic material; when the first antenna 121 and the second antenna 122 are disposed within the middle frame 110, the material of the middle frame 110 can be a non-metallic material to avoid the middle frame 110 affecting the antenna performance. In addition, there can be a plurality of gaps between the first antenna 121 and the second antenna 122 along the first direction. The above-mentioned gap 123 can be one of the plurality of gaps, or in other words, at least one of the plurality of gaps can be located between the first button 111 and the second button 112. The gaps between the antennas can be filled with a non-metallic material, for example, at least part of the structure of the middle frame 110 can be filled, so as to make the structure of the electronic device more stable. The first antenna 121 and the second antenna 122 can be of irregular shapes to adapt to the shape of the middle frame 110 and avoid other components within the middle frame 110.

[0064] To enable the first button 111 and the second button 112 to be stably disposed in the electronic device, through holes can also be provided at positions of the first antenna 121 and the second antenna 122 corresponding to the first button 111 and the second button 112. Specifically, the first antenna 121 can include a through hole 1211 and a through hole 1212. The positions of the through hole 1211 and the through hole 1212 can correspond to the positions of the first connecting post 1112A and the first connecting post 1112B respectively, and the dimension of the through hole 1211 in the y-axis direction and the dimension in the z-axis direction can be greater than the dimension of the first connecting post 1112A in the y-axis direction and the dimension in the z-axis direction respectively, so that the first connecting post 1112A can be received in the through hole 1211, and when the first button 111 is pressed, the first connecting post 1112A can displace in the through hole 1211 along the second direction. Similarly, the dimension of the through hole 1212 in the y-axis direction and the dimension in the z-axis direction can be greater than the dimension of the first connecting post 1112B in the y-axis direction and the dimension in the z-axis direction respectively, so that the first connecting post 1112B can be received in the through hole 1212. In this example, the through hole 1211 can also be referred to as the first through hole.

[0065] Further, to prevent the first button 111 from detaching from the electronic device, the projection of the first lug 1113B in the second direction and the projection of the through hole 1212 in the second direction are at least partially non - overlapping. Furthermore, the movement of the first lug 1113 in the negative x - axis direction shown in the figure can be blocked by the first antenna 121, preventing the first button 111 from detaching from the electronic device. The first lug 1113B can be the lug of the first button 111 that is away from the second button 112.

[0066] For the convenience of assembling the first button 111, the projection of the first lug 1113A in the second direction can be located within the area where the through hole 1211 is located. Or rather, the dimension of the through hole 1211 in the y - axis direction can be greater than or equal to the dimension of the first lug 1113A in the y - axis direction. The first lug 1113A can be the lug of the first button 111 that is close to the second button 112.

[0067] Similar to the structure of the first antenna 121, the second antenna 122 can include a through hole 1221 and a through hole 1222. The dimension of the through hole 1221 in the y - axis direction and the dimension in the z - axis direction can be respectively greater than the dimension of the second connecting post 1122B in the y - axis direction and the dimension in the z - axis direction. The dimension of the through hole 1222 in the y - axis direction and the dimension in the z - axis direction can be respectively greater than the dimension of the second connecting post 1122A in the y - axis direction and the dimension in the z - axis direction, so that the through holes 1221 and 1222 can respectively accommodate the second connecting posts 1122B and 1122A of the second button 112, and when the second button 112 is pressed, the second connecting posts 1122A and 1122B can respectively displace in the second direction in the through holes 1222 and 1221. The through hole 1221 can also be referred to as the second through hole.

[0068] Further, to prevent the second button 112 from detaching from the electronic device, the projection of the second lug 1123A in the second direction and the projection of the through hole 1222 in the second direction are at least partially non - overlapping. Furthermore, the movement of the second lug 1121A in the negative x - axis direction shown in the figure can be blocked by the second antenna 122, preventing the second button 112 from detaching from the electronic device. The second lug 1121A can be the lug of the second button 112 that is away from the first button 111.

[0069] For the convenience of assembling the second button 112, the projection of the second lug 1123B in the second direction can be located within the area where the through hole 1221 is located. Or rather, the dimension of the through hole 1221 in the y - axis direction can be greater than or equal to the dimension of the second lug 1123B in the y - axis direction. The second lug 1123B can be the lug of the second button 112 that is close to the first button 111.

[0070] One side of the first antenna 121 close to the middle frame 110 may further include a groove 1216. The dimension of the groove 1216 in the y-axis direction and the dimension in the z-axis direction may be respectively greater than or equal to the dimension of the first button body 1111 in the y-axis direction and the dimension in the z-axis direction. When the first button 111 is pressed, at least a part of the surface of the first button body 1111 close to the middle frame 110 may be in contact with the groove 1216, and the groove 1216 may limit the movement of the first button 111 in the positive x-axis direction. Similarly, one side of the second antenna 122 close to the middle frame 110 may include a groove 1224. The dimension of the groove 1224 in the y-axis direction and the dimension in the z-axis direction may be respectively greater than or equal to the dimension of the second button body 1121 in the y-axis direction and the dimension in the z-axis direction. When the second button 112 is pressed, at least a part of the surface of the second button body 1121 close to the middle frame 110 may be in contact with the groove 1224, and the groove 1224 may limit the movement of the second button 112 in the positive x-axis direction.

[0071] In some embodiments, the button assembly may further include a first metal bracket 151 and a second metal bracket 152. Among them, the first metal bracket 151 may be disposed on a side of the first antenna 121 away from the first button 111, or on a side of the first antenna 121 away from the first button body 1111, and the projection of the first metal bracket 151 in the second direction may be located within the area where the first antenna 121 is located. The area where the first antenna 121 is located may refer to the entire area covered by the first antenna 121, including the area where the opening on the first antenna 121 is located. The projection of the first metal bracket 151 in the second direction may be located within the area where the first antenna 121 is located, that is, the projection of the first metal bracket 151 in the second direction does not overlap with the slit 123.

[0072] The second metal bracket 152 may be disposed on a side of the second antenna 122 away from the second button 112, or on a side of the second antenna 122 away from the second button body 1121, and the projection of the second metal bracket 152 in the second direction may be located within the area where the second antenna 122 is located. The area where the second antenna 122 is located may refer to the entire area covered by the second antenna 122, including the area where the opening on the second antenna 122 is located. The projection of the second metal bracket 152 in the second direction is located within the area where the second antenna 122 is located, that is, the projection of the second metal bracket 152 in the second direction does not overlap with the slit 123.

[0073] The projections of the first metal bracket 151 and the second metal bracket 152 along the second direction are respectively located within the regions where the first antenna 121 and the second antenna 122 are located, which can avoid the first metal bracket 151 and the second metal bracket 152 from affecting the stub length of the antenna and even affecting the antenna properties, thereby reducing the coupling problem between the first antenna 121 and the second antenna 122. Moreover, the provision of the first metal bracket 151 and the second metal bracket 152 can improve the structural strength of the button assembly and reduce the problems of structural member fracture and deformation caused by multiple presses of the button.

[0074] In some embodiments, the distance between the first metal bracket 151 and the second metal bracket 152 in the first direction can be greater than the distance between the first antenna 121 and the second antenna 122 in the first direction, that is, there can be a spacing between the first metal bracket 151 and the gap 123, and there can also be a spacing between the second metal bracket 152 and the gap 123, so as to further ensure that the provision of the first metal bracket 151 and the second metal bracket 152 does not affect the performance of the first antenna 121 and the second antenna 122.

[0075] In some embodiments, the distance between the end of the first antenna 121 close to the second antenna 122 and the first metal bracket 151 in the first direction can be greater than or equal to 0.2 mm. The end of the first antenna 121 close to the second antenna 122 can be the position of the first antenna 121 closest to the second antenna 122 in the first direction. The distance between the end of the first antenna 121 close to the second antenna 122 and the first metal bracket 151 being greater than or equal to 0.2 mm can be the distance between the end of the first antenna 121 close to the second antenna 122 and the end of the first metal bracket 151 close to the gap 123 being greater than or equal to 0.2 mm.

[0076] In some embodiments, the distance between the end of the second antenna 122 close to the first antenna 121 and the second metal bracket 152 in the first direction can be greater than or equal to 0.2 mm. The end of the second antenna 122 close to the first antenna 121 can be the position of the second antenna 122 closest to the first antenna 121 in the first direction, and the distance between the end of the second antenna 122 close to the first antenna 121 and the second metal bracket 152 can be the distance between the end of the second antenna 122 close to the first antenna 121 and the end of the second metal bracket 152 close to the gap 123.

[0077] The structures of the first metal bracket 151 and the second metal bracket 152 can refer to Figure 8 the structures shown, and the first metal bracket 151 can include a first planar portion 1511, that is Figure 8The part of the first metal bracket 151 to the left of the dashed line, and the first bending part 1512, that is Figure 8 The part of the first metal bracket 151 to the right of the dashed line. The first planar part 1511 can be parallel to the yz plane shown in the figure. The first planar part 1511 can be in the form of a broken line shown in the figure, or can be in a straight-line structure ( Figure 8 not shown in the figure). The first bending part 1512 and the first planar part 1511 can be arranged at an angle. Exemplarily, Figure 8 The first bending part 1512 shown can include a first region 1512A and a second region 1512B. The first region 1512A is the region of the first bending part 1512 connected to the first planar part 1511. The fact that the first bending part 1512 and the first planar part 1511 are arranged at an angle can mean that an angle is formed between the first region 1512A and the first planar part 1511. For example, the first region 1512A and the first planar part 1511 can be in different planes, so that an angle is formed between the plane where the first region 1512A is located and the plane where the first planar part 1511 is located. The second region 1512B can be the region of the first bending part 1512 far from the first planar part 1511. The second region 1512B can be arranged at an angle with the first region 1512A. For example, the plane where the second region 1512B is located can be the yz plane shown in the figure, that is, can be parallel to the first planar part 1511. The plane where the second region 1512B is located can also not be parallel to the plane where the first planar part 1511 is located, as long as there is an angle between the second region 1512B and the first region 1512A.

[0078] When the first metal bracket 151 is connected to the non-metal bracket 130, the first bending part 1512 can be embedded in the non-metal bracket 130. For example, the first metal bracket 151 and the non-metal bracket 130 can be formed by an injection molding process, so that the first metal bracket 151 can be connected to the non-metal bracket 130 through the first bending part 1512. The first metal bracket 151 includes the first bending part 1512, which can make the connection between the first metal bracket 151 and the non-metal bracket 130 more stable, so that the two are not easily separated from each other, and enhance the structural strength of the button assembly, preventing deformation or fracture in the area where the first metal bracket 151 and the non-metal bracket 130 are close to the first lug.

[0079] Figure 8 In the first metal bracket 151 shown, the second region 1512B extends along the negative z-axis direction from the end of the first region 1512A far from the first planar part 1511. The second region 1512B can also extend along the positive z-axis direction, or can also extend at an angle with the z-axis. The present application does not limit this.

[0080] In some embodiments, the dimension of the first metal bracket 151 in the second direction may be 3 to 5 times the dimension of the first planar portion 1511 in the second direction. Taking Figure 8 the structure of the first metal bracket 151 shown as an example, the dimension of the first metal bracket 151 in the second direction may be the maximum distance in the second direction between the first planar portion 1511 and the second region 1512B, that is, Figure 8 d1 marked in Figure 8 The dimension of the first planar portion 1511 in the second direction may also be referred to as the thickness of the first planar portion 1511, that is,

[0081] d2 marked in Figure 8 The thickness of the first planar portion 1511 may also be referred to as the thickness of the first metal bracket 151, and the thicknesses of the first region 1512A and the second region 1512B may be the same as the thickness of the first planar portion 1511, where the thickness of the first region 1512A may be the dimension of the first region 1512A in the direction perpendicular to the main plane of the first region 1512A. Figure 8 Figure 8 Figure 8 The second bent portion 1522 and the second planar portion 1521 may be arranged at an angle. Exemplarily, Figure 8The second bending portion 1522 shown may include a third region 1522A and a fourth region 1522B. The third region 1522A is the region of the second bending portion 1522 connected to the second planar portion 1521. The fact that the second bending portion 1522 and the second planar portion 1521 are arranged at an angle may mean that the third region 1522A and the second planar portion 1521 are arranged at an angle. For example, the third region 1522A and the second planar portion 1521 may be located on different planes, such that the plane where the third region 1522A is located and the plane where the second planar portion 1521 is located are arranged at an angle. The fourth region 1522B may be the region of the second bending portion 1522 far from the second planar portion 1521. The fourth region 1522B may be arranged at an angle with the third region 1522A. For example, the plane where the fourth region 1522B is located may be the yz plane shown in the figure, that is, it may be parallel to the second planar portion 1521. The plane where the fourth region 1522B is located may also not be parallel to the plane where the second planar portion 1521 is located, as long as there is an angle between the fourth region 1522B and the third region 1522A.

[0082] When the second metal bracket 152 is connected to the non-metal bracket, the second bending portion 1522 may be embedded in the non-metal bracket 130. For example, the second metal bracket 152 and the non-metal bracket 130 may be formed by an injection molding process, such that the second metal bracket 152 can be connected to the non-metal bracket 130 through the second bending portion 1522. The second metal bracket 152 includes the second bending portion 1522, which can make the connection between the second metal bracket 152 and the non-metal bracket 130 more stable, so that the two are not easily separated from each other, and enhance the structural strength of the second metal bracket 152 and the non-metal bracket.

[0083] Figure 8 In the second metal bracket 152 shown, the fourth region 1522B may extend along the negative z-axis direction from one end of the third region 1522A far from the second planar portion 1521. The fourth region 1522B may also extend along the positive z-axis direction, or may extend at an angle with the z-axis.

[0084] In some embodiments, the dimension of the second metal bracket 152 in the second direction may be 3 to 5 times the dimension of the second planar portion 1521 in the second direction. For Figure 8The structure of the second metal bracket 152 shown is similar to that of the first metal bracket 151. The dimension of the second metal bracket 152 in the second direction can be the maximum distance in the second direction between the second planar portion 1521 and the fourth region 1522B. The dimension of the second planar portion 1521 in the second direction can also be referred to as the thickness of the second planar portion 1521, or can also be referred to as the thickness of the second metal bracket 152. The thicknesses of the third region 1522A and the fourth region 1522B can be the same as the thickness of the second planar portion 1521. The dimension of the second metal bracket 152 in the second direction can be the same as or different from the dimension of the first metal bracket 151 in the second direction. The dimension of the second planar portion 1521 in the second direction can be the same as or different from the dimension of the first planar portion 1511 in the second direction.

[0085] Figure 9 It is a schematic structural diagram of another metal bracket provided by an embodiment of the present application. For the first metal bracket 151, the first planar portion 1511 and the first bending portion 1512 can also be located on the same plane. The first planar portion 1511 and the first bending portion 1512 can form a linear structure as shown in the figure. Among them, the first planar portion 1511 can extend along the y-axis direction shown in the figure, and the first bending portion 1512 can extend along the z-axis direction shown in the figure, so that the first planar portion 1511 and the first bending portion 1512 are arranged at an angle. Similar to Figure 8 the metal bracket described, the Figure 9 shown first bending portion 1512 can be embedded in the non-metal bracket 130. The first metal bracket 151 can be connected to the non-metal bracket 130 through the first bending portion 1512, so that the connection between the first metal bracket 151 and the non-metal bracket 130 can be more stable and not easily detached.

[0086] The second planar portion 1521 and the second bending portion 1522 of the second metal bracket 152 can also be located on the same plane, and the second planar portion 1521 and the second bending portion 1522 can be linear. The second planar portion 1521 can extend along the y-axis direction shown in the figure, and the second bending portion 1522 can extend along the z-axis direction shown in the figure, so that the second planar portion 1521 and the second bending portion 1522 are arranged at an angle. The second metal bracket 152 can be connected to the non-metal bracket through the second bending portion 1522, so that the connection between the second metal bracket 152 and the non-metal bracket 130 can be more stable and not easily detached.

[0087] When the entirety of the first metal bracket 151 and the second metal bracket 152 is in the planar structure, the dimensions of the first metal bracket 151 and the second metal bracket 152 in the second direction are respectively the same as the dimensions of the first planar portion 1511 and the second planar portion 1521 in the second direction. The dimension of the first metal bracket 151 in the second direction may be the same as or different from the dimension of the second metal bracket 152 in the second direction.

[0088] It should be noted that Figure 8 and Figure 9 the dashed lines in are only for indicating the positions of the planar portions and the bent portions of the metal brackets, and should not limit the structure of the metal brackets themselves.

[0089] In some embodiments, the material of the first metal bracket 151 and / or the second metal bracket 152 may be steel or copper alloy. For example, the material of the first metal bracket 151 and / or the second metal bracket 152 may be 301 stainless steel, 304 stainless steel, 316 stainless steel. Among them, 301, 304, and 316 may be the steel grades of steel. Alternatively, the material of the first metal bracket 151 and / or the second metal bracket 152 may also be materials such as cupronickel. The first metal bracket 151 and / or the second metal bracket 152 being made of steel or copper alloy can make the first metal bracket 151 and the second metal bracket 152 have higher strength and good plasticity, facilitating the bending of the first metal bracket 151 and the second metal bracket 152, so that the first metal bracket 151 and the second metal bracket 152 have a height in the second direction. For example Figure 8 the first metal bracket 151 and the second metal bracket 152 shown in can be bent from a planar metal sheet along a preset position, so that at least part of the structures of the first metal bracket 151 and the second metal bracket 152 are not in the same plane as the rest, and have a height in the second direction. Furthermore, when the first metal bracket 151 and the second metal bracket 152 are connected to the non-metal bracket 130, they are not easily separated from the non-metal bracket 130.

[0090] As described above, the first metal bracket 151 and the second metal bracket 152 can be respectively connected to the non-metal bracket 130 through the first bent portion 1512 and the second bent portion 1522. Correspondingly, as Figure 10In the structure shown, the non-metallic bracket 130 may include a main body portion 131 and protruding portions 132. The main body portion 131 may be linear. One side of the main body portion 131 away from the first button 111 may include one or more grooves (not shown in the figure) for accommodating the FPC 170. The protruding portions 132 may be provided on one side of the main body portion 131 in the z-axis direction. The number of the protruding portions 132 may be two, for example, may include the protruding portions 132A and 132B shown in the figure. Among them, the protruding portion 132A may be connected to the first metal bracket 151, and the protruding portion 132B may be connected to the second metal bracket 152. For the structure in which the non-metallic bracket 130 is fixedly connected to the first metal bracket 151 and the second metal bracket 152, reference may be made to Figure 11 the overall structural schematic diagram of the button bracket described above or Figure 12 the cross-sectional structural schematic diagram of the button bracket shown along the xy plane. Among them, the enlarged cross-sectional structural diagrams of the connection between the first metal bracket 151 and the non-metallic bracket 130 and the connection between the second metal bracket 152 and the non-metallic bracket 130 are respectively shown in the circles. Exemplarily, the first bent portion 1511 and the second bent portion 1512 may be respectively embedded in the protruding portions 132A and 132B through an injection molding process. The dimension of the protruding portion 132A in the x-axis direction may be greater than the dimension of the first metal bracket 151 in the x-axis direction, so that the entire second bent portion 1512 may be disposed within the protruding portion 132A. The dimension of the protruding portion 132B in the x-axis direction may be greater than the dimension of the second metal bracket 151 in the x-axis direction, so that the entire second bent portion 1522 may be disposed within the protruding portion 132B to respectively achieve the connection between the first metal bracket 151 and the second metal bracket 152 and the non-metallic bracket 130. And when the non-metallic bracket 130 is connected to the first metal bracket 152 and the second metal bracket 152, the first planar portion 1511 may be parallel to the second planar portion 1521, and may be parallel to the main planes of the protruding portions 132A and 132B.

[0091] When the first metal bracket 151, the second metal bracket 152, and the non-metallic bracket 130 are disposed in the button assembly or the electronic device, one ends of the protruding portions 132A and 132B away from the main body portion 131 may be disposed in the grooves of the middle frame (not shown in the figure) to support the non-metallic bracket 130 and enable the first planar portion 1511 and the second planar portion 1522 to be respectively located on the through holes 1211 and 1221, restricting the displacement of the first lug 1113A and the second lug 1123B in the negative x-axis direction.

[0092] Continue to refer to Figure 4In the cross-sectional structure shown, when the first metal bracket 151 is disposed in the electronic device, at least a part of the first metal bracket 151 can be disposed on the through hole 1211. Or rather, the projection of the first metal bracket 151 in the second direction can at least partially overlap with the through hole 1211. Moreover, at least a part of the first metal bracket 151 can be disposed between the first lug 1113A and the first antenna 121 in the second direction, and the projection of the first metal bracket 151 in the second direction at least partially overlaps with the projection of the first lug 1113A in the second direction. Thus, the movement of the first lug 1113A in the negative x-axis direction can be blocked by the first metal bracket 151, preventing the first button 111 from coming out of the through hole 1211 and separating from the electronic device during use. Exemplarily, for Figure 8 or Figure 9 the first metal bracket 151 shown, the end of the first planar portion 1511 can be disposed on the through hole 1211. Or rather, at least a part of the structure of the first planar portion 1511 away from the first bending portion 1512 can be disposed on the through hole 1211, and this part of the structure can be disposed between the first antenna 121 and the first lug 1113A, such that the movement of the first lug 1113A in the negative x-axis direction can be blocked by this part of the structure.

[0093] Similarly, when the second metal bracket 152 is disposed in the electronic device, at least a part of the second metal bracket 152 can be disposed on the through hole 1221. Or rather, the projection of the second metal bracket 152 in the second direction at least partially overlaps with the through hole 1221. Moreover, at least a part of the second metal bracket 152 can be disposed between the second lug 1123B and the second antenna 122 in the second direction, and the projection of the second metal bracket 152 in the second direction at least partially overlaps with the projection of the second lug 1123B in the second direction. Thus, the movement of the second lug 1123B in the negative x-axis direction can be blocked by the second metal bracket 152, preventing the second button 112 from coming out of the through hole 1221 and separating from the electronic device during use. For Figure 8 or Figure 9 the second metal bracket 152 shown, the end of the second planar portion 1521 can be disposed on the through hole 1221. Or rather, at least a part of the structure of the second planar portion 1521 away from the second bending portion 1522 can be disposed on the through hole 1221, and this part of the structure can be disposed between the second antenna 122 and the second lug 1123B, such that the movement of the first lug 1123B in the negative x-axis direction can be blocked by this part of the structure.

[0094] It should be noted that Figure 4In the key assembly shown, the first lugs 1113B are connected to the first antenna 121, and the first lugs 1113A are connected to the first metal bracket 151. That is, the projection of the first lugs 1113B in the second direction and the projection of the first antenna 121 in the second direction at least partially overlap, and the projection of the first lugs 1113A in the second direction and the projection of the first metal bracket 151 in the second direction at least partially overlap, so that the movement of the first lugs 1113B in the negative x-axis direction shown in the figure can be blocked by the middle frame 110, and the movement of the first lugs 1113A in the negative x-axis direction can be blocked by the first metal bracket 151. In the embodiment provided in the present application, it is also possible that the first lugs 1113A are connected to the first antenna 121 and the first lugs 1113B are connected to the first metal bracket 151. That is to say, the first metal bracket 151 can also be arranged on the through hole 1212. The projection of the first lugs 1113A in the second direction and the projection of the first antenna 121 in the second direction at least partially overlap, and the projection of the first lugs 1113B in the second direction and the projection of the first metal bracket 151 in the second direction at least partially overlap, so that the movement of the first lugs 1113A in the negative x-axis direction shown in the figure can be blocked by the first antenna 121, and the movement of the first lugs 1113B in the negative x-axis direction shown in the figure can be blocked by the first metal bracket 151. Similar to the structures of the first key 111 and the first metal bracket 151, the second metal bracket 152 can be arranged at one end where the second lugs 1123B are located and connected to the second lugs 1123B, or can be arranged at one end where the second lugs 1123A are located and connected to the second lugs 1123A, which will not be elaborated here.

[0095] Continue to refer to Figure 3 or Figure 4 In the structure shown, the key assembly may further include a circuit board 170. The circuit board 170 may be an FPC. The circuit board 170 may be arranged on the side of the first antenna 121 away from the first key body 1111. The side of the circuit board 170 close to the first key 111 may include a trigger switch. When the first key 111 and the second key 112 are pressed, the trigger switch can be triggered to realize different functions of the electronic device.

[0096] Specifically, when the first key 111 is a volume key, the first key 111 may include a first trigger portion 1114. The number of the first trigger portions 1114 may be 2, for example, including a first trigger portion 1114A and a first trigger portion 1114B, as Figure 5as shown in (a) therein. The first trigger portions 1114A and 1114B can be arranged along the first direction and can be disposed on the same side of the first connection post 1112 on the first button body 1111. The first trigger portions 1114A and 1114B can be in the columnar structure shown in the figure. Correspondingly, the first antenna 121 can include through holes 1213 and 1214, as Figure 7 shown. The positions of the through holes 1213 and 1214 can correspond to the positions of the first trigger portions 1114A and 1114B respectively, and can also correspond to the positions of the trigger switches 161 and 162 respectively. The radial dimension of the through hole 1213 can be greater than or equal to the radial dimension of the first trigger portion 1114A, and the radial dimension of the through hole 1214 can be greater than or equal to the radial dimension of the first trigger portion 1114B. Thus, at least a part of the first trigger portion 1114A can be received in the through hole 1213, and at least a part of the first trigger portion 1114B can be received in the through hole 1214. Moreover, when one end of the first button 111 away from the second button 112 is pressed, one end of the first button 111 away from the second button 112 can be displaced in the positive x-axis direction. Correspondingly, the first trigger portion 1114A can be displaced in the through hole 1213 in the positive x-axis direction and contact the trigger switch 161 to trigger corresponding functions, such as increasing the volume, etc. Similarly, when one end of the first button 111 close to the second button 112 is pressed, one end of the first button close to the second button 112 can be displaced in the positive x-axis direction, and the trigger portion 1114B can be displaced in the through hole 1214 in the positive x-axis direction and contact the trigger switch 162 to trigger corresponding functions, such as decreasing the volume, etc.

[0097] When the second button 112 is a power button, the second button 112 can include a second trigger portion 1124. The number of the second trigger portions 1124 can be one, as Figure 6 shown. The trigger portion 1124 can be disposed between the second lugs 1123A and 1123B, for example, can be disposed at the middle position of the second button body 1121. And the trigger portion 1124 and the second connection post 1122 can be disposed on the same side of the second button body 1121. The trigger portion 1124 can be in the columnar structure. Correspondingly, the second antenna 122 can include a through hole 1223, as Figure 8 shown. The position of the through hole 1223 can correspond to the position of the trigger portion 1124, and the radial dimension of the through hole 1223 can be greater than or equal to the radial dimension of the trigger portion 1124. When the second button 112 is pressed, at least a part of the second button 112 can be displaced in the positive x-axis direction, at least a part of the trigger portion 1124 can pass through the through hole 1223, contact the trigger switch 163, and trigger corresponding functions, such as lighting or extinguishing the screen, etc.

[0098] The first button 111 may further include a foam 1115. The foam 1115 and the first connecting post 1112 may be disposed on the same side of the first button 111, and the foam 1115 may be disposed at the center of the first button 111. The foam 1115 may be used to maintain the balance of the first button 111.

[0099] The embodiment of the present application further provides a method for manufacturing a button bracket. This method can be used to manufacture the above-mentioned first metal bracket, second metal bracket, and non-metal bracket. This method may include steps S1301 to S1303, as Figure 13 shown.

[0100] S1301: Manufacture a metal bracket, which includes a first metal bracket, a second metal bracket, and a metal connecting material. At least a part of the metal connecting material is disposed between the first metal bracket and the second metal bracket.

[0101] S1302: Manufacture a non-metal bracket by using an injection molding process. The first metal bracket and the second metal bracket are respectively connected to the non-metal bracket.

[0102] S1303: Remove the metal connecting material.

[0103] Among them, for step S1301, the structures of the first metal bracket 1511, the second metal bracket 152, and the metal connecting material 153 can be referred to the Figure 14 schematic diagram of the bracket structure shown. The metal connecting material 153 may include a first part 1531 and a second part 1532. The first part 1531 may have a bar-shaped structure as shown in the figure. The number of the second parts 1532 may be two, and the second parts 1532 may be protruding parts on the first part 1531. The two second parts 1532 may be respectively connected to the first metal bracket 151 and the second metal bracket 152. The first metal bracket 151, the second metal bracket 152, and the metal connecting material 153 may be an integrally formed structure, for example, integrally formed by processes such as forging.

[0104] In some embodiments, there may be a groove 1541 between the metal connecting material 153 and the first metal bracket 151, and there may be a groove 1542 between the metal connecting material 153 and the second metal bracket 152. The groove 1541 and the groove 1542 may be formed by processes such as cutting. The groove 1541 and 1542 may be used to facilitate disconnecting the metal connecting material 153 from the first metal bracket 151 and the second metal bracket 152 when assembling the first metal bracket 151 and the second metal bracket 152 into an electronic device.

[0105] For step S1302, when manufacturing the non-metal bracket using the injection molding process, the molten non-metal can be injected into the mold. The molten non-metal can be, for example, molten resin, which forms the non-metal bracket after cooling. During the injection molding process, the first metal bracket and the second metal bracket can be embedded at preset positions in the mold, so that after the non-metal melt cools and forms, the first metal bracket and the second metal bracket can be fixedly connected to it. Furthermore, after demolding, Figure 14 the structure of the key bracket shown can be obtained. A metal connecting material is provided between the first metal bracket and the second metal bracket, which can prevent relative displacement between the first metal bracket and the second metal bracket under the push of the injected non-metal melt during the injection molding process.

[0106] For step S1303, after the non-metal bracket cools and forms, the first metal bracket and the second metal bracket can be stably connected to the non-metal bracket, and then Figure 14 the metal connecting material 153 is removed by breaking or cutting the grooves 1541 and 1542 in to obtain Figure 11 the key bracket shown.

[0107] The embodiment of the present application also provides an electronic device, which may include a key assembly as described in Figures 3 to 12 . The electronic device can be a mobile phone, a tablet computer, a smart watch, a TV, a smart screen, a camera, etc. that includes the key assembly. The type of the electronic device is not limited in the present application.

[0108] It should be noted that in the embodiment of the present application, the "same" size of the structural member does not mean absolute sameness. Those skilled in the art can understand that since those skilled in the art can appropriately adjust the size of the structural member according to the design requirements, the "same" size of the two structural members allows a deviation within a certain range, such as a difference of 0.1 mm to 0.5 mm, etc. Similarly, the mutual parallelism or perpendicularity in terms of angles can also be approximately parallel or perpendicular.

[0109] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present application, and all should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claimed rights.
