Description

Key assembly, electronic device, and key bracket manufacturing method

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on December 17, 2023, with application number 202311744672.9 and invention name “Method for manufacturing a key assembly, electronic device and key bracket”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electronic devices, and in particular to a method for manufacturing a key assembly, an electronic device, and a key bracket. Background Art

[0003] Electronic devices typically feature multiple antennas to support various communication functions, such as Bluetooth, wireless hotspot (Wi-Fi), and calls. Antenna slots are placed between the antennas to reduce coupling issues. When the antenna slot is positioned in the middle of the side button of an electronic device, the structure must meet both side button assembly strength and antenna performance requirements.

[0004] Conventional technology typically uses a flexible printed circuit (FPC) bracket made of pure plastic. This FPC bracket can be placed on the side of the antenna away from the side button to prevent poor coupling between the two antenna branches. At least a portion of this FPC bracket can also be connected to the side button's mounting lug to prevent the side button from detaching from the electronic device. However, pure plastic FPC brackets have poor overall strength, and the portion of the bracket that connects to the side button mounting lug is particularly susceptible to deformation or even breakage. Placing steel sheets at the antenna seam to increase structural strength can cause changes in the length of the antenna branches and even alter the antenna's properties, making it difficult to meet antenna functional requirements.

[0056] Figure 1 is a schematic structural diagram of an electronic device 100. The button assembly can be set on the side edge of the electronic device 100, for example, it can be set on the right side of the electronic device 100. For example, the button assembly can include a power button 112 and a volume button 111. The power button 112 can be used to realize functions such as turning on and off the screen of the electronic device 100, shutting down and starting up the electronic device 100, and the volume button 111 can be used to realize functions such as increasing or decreasing the volume of audio and video playback of the electronic device 100, as well as 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 set on the same side of the electronic device 100, or they can be set on different sides of the electronic device 100. The button assembly structure needs to meet strength requirements so that the button assembly can withstand multiple presses without deformation or breakage.

[0057] The electronic device 100 is typically equipped with multiple antennas to meet different communication needs. Gaps are provided between the antennas to reduce poor coupling between them. When the gaps between the antennas are located near or near buttons, the structure must meet both button strength and antenna performance requirements.

[0058] Figure 2 is a schematic diagram of the structure of a conventional button assembly. The middle frame 110 can be made of non-metallic material. The first antenna 121 and the second antenna 122 are disposed within the middle frame 110. A plastic bracket 130, also referred to as a non-metallic bracket, is disposed on the side of the first antenna 121 and the second antenna 122 away from the first button 111 and the second button 112. This plastic bracket 130 can also be called a non-metallic bracket and can be used to support an 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 into which the FPC can be disposed. Furthermore, a mounting lug for the first button 111 and a mounting lug for 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. While the use of the plastic bracket 130 can reduce the problem of poor coupling between the two antenna branches, the overall strength of the plastic bracket 130 is relatively poor, and the portion of the plastic bracket 130 located at the mounting lug is particularly susceptible to breakage or deformation. However, placing steel sheets at the antenna slots to improve structural strength can easily cause the length of the antenna branches to change, or even change the antenna properties, making it difficult to meet the antenna functional requirements. Therefore, it is necessary to provide a key assembly that can meet both the antenna performance requirements and the key structural strength requirements.

[0059] The structure of the key assembly provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings. First, please refer to the exploded structure diagram of the key assembly shown in FIG3 and the cross-sectional structure diagram of the key assembly along the xy plane shown in FIG4.

[0060] 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 a portion disposed outside the middle frame 110 of the electronic device so that a user can press the first button 111 and the second button 112. The first button 111 and the second button 112 may also include a portion disposed inside the middle frame 110 of the electronic device, for electrically connecting the first button 111 and the second button 112 to the circuit board when the first button 111 and the second button 112 are pressed, thereby realizing different functions of the electronic device.

[0061] Specifically, referring to the key structure shown in FIG5 , FIG5 (a) shows the structure of the first key 111, and FIG5 (b) shows the structure of the second key 112. As shown in FIG5 (a), the first key 111 may include a first key body 1111. The cross-sectional shape of the first key body 1111 along the yz plane may be, for example, an annular or rectangular shape. The first key 111 may also include a first hanging ear 1113. The number of the first hanging ears 1113 may be two, for example, including first hanging ears 1113A and 1113B, and may be respectively disposed at the two ends of the first key body 1111. The two ends of the first key body 1111 may refer to the two ends of the first key body 1111 along the first direction. The principal plane of the first mounting ear 1113 can be parallel to the principal plane of the first button body 1111. The principal plane of the first button body 1111 can refer to the surface of the first button body 1111 with the largest planar surface area, namely, the yz plane shown in the figure. The principal plane of the first button body 1111 can also be referred to as the principal plane of the first button 111. Similarly, the principal plane of the first mounting ear 1113 can refer to the surface of the first mounting ear 1113 with the largest planar surface area, namely, the yz plane shown in the figure. The first button 111 can also include a first connecting post 1112. The first connecting post 1112 can be disposed between the first mounting ear 1113 and the first button body 1111 to connect the first mounting ear 1113 and the first button body 1111. When the first button 111 is installed in an electronic device, the first button body 1111 can be at least partially located outside the middle frame 110 for a user to press the first button 111, while the first mounting ear 1113 and the first connecting post 1112 can be located inside the middle frame 110.

[0062] As shown in FIG5(b), 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 size of the second button 112 along the y-axis may be smaller than the size of the first button along the y-axis. The second button 112 may include two second mounting ears 1123, for example, including second mounting ears 1123A and 1123B, which may be respectively disposed at opposite ends of the second button body 1121. The second button 112 may also include a second connecting post 1122, which may be disposed between the second mounting ear 1123 and the second button body 1121 to connect the second mounting ear 1123 and the second button body 1121. When the second button 112 is set in an electronic device, at least part of the second button body 1121 can be located outside the middle frame 110 for the user to press the second button 112, while the second hanging ear 1123 and the second connecting column 1122 can be located inside the middle frame 110.

[0063] For example, the structure of the middle frame can refer to the structure shown in FIG6 . The middle frame 110 can include a through hole 113. The position of the through hole 113 can correspond to the position of the first button 111. The size of the through hole 113 along the y-axis direction can be the same as the size of the first button body 1111 along the y-axis direction. The size of the through hole 113 along the z-axis direction can be the same as the size of the first button body 1111 along the z-axis direction. This allows the first button body 1111 to be at least partially accommodated in the through hole 113. When the first button 111 is pressed, the first button body 1111 can be displaced in a second direction within the through hole 113. The second direction can 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 also include a through hole 114, the position of the through hole 114 may correspond to the position of the second button 112, and the size of the through hole 114 along the y-axis direction may be the same as the size of the second button body 1121 along the y-axis direction, and the size of the through hole 114 along the z-axis direction may be the same as the size of the second button body 1121 along the z-axis direction, so that the second button body 1121 can be at least partially accommodated in the through hole 114, and when the second button 112 is pressed, the second button body 1121 can be displaced along the second direction in the through hole 114.

[0064] The key assembly may also include a first antenna 121 and a second antenna 122. The structures of the first antenna 121 and the second antenna 122 can be shown in the antenna structure diagram shown in FIG7 . The first antenna 121 and the second antenna 122 can be disposed within the middle frame 110, that is, on a side of the middle frame 110 away from the first key body 1111. A gap 123 may be formed between the first antenna 121 and the second antenna 122 in the first direction. The gap 123 may be formed by the first and second antennas 121 and 122 at their respective ends, which are close to each other in the first direction. The gap 123 may be located between the first and second keys 111 and 112. For example, the gap 123 may have a dimension in the first direction of 0.8 mm to 1.2 mm, that is, the distance between the first and second antennas 121 and 122 at their respective ends in the first direction may be 0.8 mm to 1.2 mm.

[0065] It should be noted that the first antenna 121 and the second antenna 122 can be disposed within the middle frame 110 or can be part of the middle frame 110. The first antenna 121 and the second antenna 122 being part of the middle frame 110 can refer to reusing the structure of the middle frame 110 to implement antenna functions, thereby reducing the size and weight of the electronic device. This application does not limit the shape and structure 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 metal. 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 non-metallic to prevent the middle frame 110 from affecting the antenna performance. In addition, multiple gaps can be formed between the first antenna 121 and the second antenna 122 along the first direction. The gap 123 can be one of these gaps, or at least one of the multiple gaps can be located between the first button 111 and the second button 112. The gap between the antennas can be filled with a non-metallic material, such as at least a portion of the structure of the middle frame 110, to provide greater structural stability for the electronic device. The first antenna 121 and the second antenna 122 can have irregular shapes to adapt to the shape of the middle frame 110 and avoid other components within the middle frame 110.

[0066] To ensure that the first button 111 and the second button 112 can be stably disposed in the electronic device, through holes can also be provided on the first antenna 121 and the second antenna 122 at positions 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 holes 1211 and 1212 can correspond to the positions of the first connecting post 1112A and the first connecting post 1112B, respectively. The dimensions of the through hole 1211 along the y-axis and along the z-axis can be larger than the dimensions of the first connecting post 1112A along the y-axis and along the z-axis, respectively, so that the first connecting post 1112A can be accommodated in the through hole 1211. When the first button 111 is pressed, the first connecting post 1112A can be displaced in the second direction within the through hole 1211. Similarly, the dimensions of the through hole 1212 along the y-axis and along the z-axis can be respectively larger than the dimensions of the first connecting pillar 1112B along the y-axis and along the z-axis, so that the first connecting pillar 1112B can be accommodated in the through hole 1212. In this example, the through hole 1211 can also be referred to as a first through hole.

[0067] Furthermore, to prevent the first button 111 from detaching from the electronic device, the projection of the first hanging ear 1113B along the second direction and the projection of the through hole 1212 along the second direction at least partially do not overlap. Consequently, the movement of the first hanging ear 1113 along the negative x-axis (as shown) can be blocked by the first antenna 121, preventing the first button 111 from detaching from the electronic device. The first hanging ear 1113B can be the hanging ear of the first button 111 that is away from the second button 112.

[0068] To facilitate assembly of the first button 111, the projection of the first hanging ear 1113A along the second direction can be located within the region where the through hole 1211 is located. In other words, the dimension of the through hole 1211 along the y-axis can be greater than or equal to the dimension of the first hanging ear 1113A along the y-axis. The first hanging ear 1113A can be the hanging ear of the first button 111 that is closest to the second button 112.

[0069] Similar to the structure of the first antenna 121, the second antenna 122 may include a through hole 1221 and a through hole 1222. The dimensions of the through hole 1221 along the y-axis and along the z-axis may be larger than the dimensions of the second connecting post 1122B along the y-axis and along the z-axis, respectively. The dimensions of the through hole 1222 along the y-axis and along the z-axis may be larger than the dimensions of the second connecting post 1122A along the y-axis and along the z-axis, respectively. This allows the through holes 1221 and 1222 to respectively accommodate the second connecting posts 1122B and 1122A of the second button 112, and allows the second connecting posts 1122A and 1122B to respectively displace in the second direction within the through holes 1222 and 1221 when the second button 112 is pressed. The through hole 1221 may also be referred to as a second through hole.

[0070] Furthermore, to prevent the second button 112 from detaching from the electronic device, the projection of the second hanging ear 1123A along the second direction and the projection of the through hole 1222 along the second direction at least partially do not overlap. Consequently, the movement of the second hanging ear 1121A along the negative x-axis (as shown) can be blocked by the second antenna 122, thereby preventing the second button 112 from detaching from the electronic device. The second hanging ear 1121A can be the hanging ear of the second button 112 that is away from the first button 111.

[0071] To facilitate assembly of the second button 112, the projection of the second hanging ear 1123B along the second direction can be located within the region where the through hole 1221 is located. In other words, the dimension of the through hole 1221 along the y-axis can be greater than or equal to the dimension of the second hanging ear 1123B along the y-axis. The second hanging ear 1123B can be the hanging ear of the second button 112 that is closest to the first button 111.

[0072] The side of the first antenna 121 close to the middle frame 110 may also include a groove 1216. The size of the groove 1216 along the y-axis direction and the size along the z-axis direction may be greater than or equal to the size of the first button body 1111 along the y-axis direction and the size along the z-axis direction, respectively. When the first button 111 is pressed, at least a portion of the side of the first button body 1111 close to the middle frame 110 may contact the groove 1216. The groove 1216 may limit the movement of the first button 111 along the positive direction of the x-axis. Similarly, the side of the second antenna 122 close to the middle frame 110 may include a groove 1224, and the size of the groove 1224 along the y-axis direction and the size along the z-axis direction may be respectively greater than or equal to the size of the second button body 1121 along the y-axis direction and the size along the z-axis direction. When the second button 112 is pressed, at least a portion of the side of the second button body 1121 close to the middle frame 110 may contact the groove 1224, and the groove 1224 may limit the movement of the second button 112 along the positive direction of the x-axis.

[0073] In some embodiments, the button assembly may further include a first metal bracket 151 and a second metal bracket 152, wherein the first metal bracket 151 may be disposed on a side of the first antenna 121 away from the first button 111, or in other words, on a side of the first antenna 121 away from the first button body 1111, and the projection of the first metal bracket 151 along 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 area covered by the entire first antenna 121, including the area where the opening of the first antenna 121 is located. The projection of the first metal bracket 151 along 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 along the second direction does not overlap with the gap 123.

[0074] The second metal bracket 152 can be disposed on a side of the second antenna 122 away from the second button 112, or in other words, on a side of the second antenna 122 away from the second button body 1121. The projection of the second metal bracket 152 along the second direction can be located within the area where the second antenna 122 is located. The area where the second antenna 122 is located can refer to the entire area covered by the second antenna 122, including the area where the opening of the second antenna 122 is located. The projection of the second metal bracket 152 along the second direction is located within the area where the second antenna 122 is located. In other words, the projection of the second metal bracket 152 along the second direction does not overlap with the gap 123.

[0075] The projections of the first and second metal brackets 151, 152 along the second direction are located within the areas of the first and second antennas 121, 122, respectively. This prevents the first and second metal brackets 151, 152 from affecting the length of the antenna branches, or even affecting the antenna properties, thereby reducing coupling issues between the first and second antennas 121, 122. Furthermore, the provision of the first and second metal brackets 151, 152 improves the structural strength of the key assembly, reducing the risk of structural component breakage and deformation caused by repeated key presses.

[0076] 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 distance between the first metal bracket 151 and the gap 123, and there can also be a distance between the second metal bracket 152 and the gap 123, so as to further ensure that the setting 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.

[0077] In some embodiments, the distance in the first direction between the end of the first antenna 121 near the second antenna 122 and the first metal bracket 151 can be greater than or equal to 0.2 mm. The end of the first antenna 121 near 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 near the second antenna 122 and the first metal bracket 151 is greater than or equal to 0.2 mm, or the distance between the end of the first antenna 121 near the second antenna 122 and the end of the first metal bracket 151 near the gap 123 is greater than or equal to 0.2 mm.

[0078] In some embodiments, the distance in the first direction between the end of the second antenna 122 near the first antenna 121 and the second metal bracket 152 may be greater than or equal to 0.2 mm. The end of the second antenna 122 near the first antenna 121 may 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 near the first antenna 121 and the second metal bracket 152 may be the distance between the end of the second antenna 122 near the first antenna 121 and the end of the second metal bracket 152 near the gap 123.

[0079] The structure of the first metal bracket 151 and the second metal bracket 152 can be seen in the structure shown in Figure 8. The first metal bracket 151 can include a first planar portion 1511, which is the portion of the first metal bracket 151 located to the left of the dotted line in Figure 8, and a first bent portion 1512, which is the portion of the first metal bracket 151 located to the right of the dotted line in Figure 8. The first planar portion 1511 can be parallel to the yz plane shown in the figure. The first planar portion 1511 can be in a broken line shape as shown, or it can be a straight line structure (not shown in Figure 8). The first bent portion 1512 can be arranged at an angle to the first planar portion 1511. For example, the first bent portion 1512 shown in FIG8 may include a first region 1512A and a second region 1512B. The first region 1512A is a region of the first bent portion 1512 connected to the first planar portion 1511. The angle between the first bent portion 1512 and the first planar portion 1511 may refer to an angle between the first region 1512A and the first planar portion 1511. For example, the first region 1512A and the first planar portion 1511 may be located on different planes, such that an angle is formed between the plane where the first region 1512A is located and the plane where the first planar portion 1511 is located. The second region 1512B may be a region of the first bent portion 1512 away from the first planar portion 1511. The second region 1512B may be an angle with the first region 1512A. For example, the plane where the second region 1512B is located may be the yz plane shown in the figure, that is, it may be parallel to the first planar portion 1511. The plane where the second area 1512B is located may not be parallel to the plane where the first planar portion 1511 is located. It is only necessary that there is an angle between the second area 1512B and the first area 1512A.

[0080] When the first metal bracket 151 is connected to the non-metal bracket 130, the first bent portion 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 through an injection molding process, so that the first metal bracket 151 is connected to the non-metal bracket 130 via the first bent portion 1512. The first metal bracket 151 includes the first bent portion 1512, which can make the connection between the first metal bracket 151 and the non-metal bracket 130 more stable, making it difficult for the two to separate from each other, and enhance the structural strength of the key assembly, preventing deformation or fracture of the first metal bracket 151 and the non-metal bracket 130 in the area near the first hanging ear.

[0081] In the first metal bracket 151 shown in Figure 8, the second region 1512B extends from the end of the first region 1512A away from the first planar portion 1511 along the negative direction of the z-axis. The second region 1512B can also extend along the positive direction of the z-axis, or can also extend at an angle to the z-axis. This application does not limit this.

[0082] In some embodiments, the size of the first metal bracket 151 along the second direction can be 3 to 5 times the size of the first planar portion 1511 along the second direction. Taking the first metal bracket 151 structure shown in FIG8 as an example, the size of the first metal bracket 151 along the second direction can be the maximum distance between the first planar portion 1511 and the second region 1512B in the second direction, which is d1 in FIG8 . The size of the first planar portion 1511 along the second direction can also be referred to as the thickness of the first planar portion 1511, which is d2 in FIG8 . The thickness of the first planar portion 1511 can also be referred to as the thickness of the first metal bracket 1511, and the thickness of the first region 1512A and the second region 1512B can be the same as the thickness of the first planar portion 1511, wherein the thickness of the first region 1512A can be the size of the first region 1512A along a direction perpendicular to the main plane of the first region 1512A.

[0083] Similar to the structure of the first metal bracket 151, the second metal bracket 152 can include a second planar portion 1521 and a second bent portion 1522. The second planar portion 1521 is the portion of the second metal bracket 152 located to the right of the dashed line in Figure 8, and the second bent portion 1522 is the portion of the second metal bracket 152 located to the left of the dashed line in Figure 8. The second planar portion 1521 can be parallel to the yz plane shown in the figure. The second planar portion 1521 can be in a zigzag shape as shown, or it can be a straight line structure (not shown in Figure 8). The second bent portion 1522 can be arranged at an angle to the second planar portion 1521. For example, the second bent portion 1522 shown in FIG8 may include a third region 1522A and a fourth region 1522B. The third region 1522A is the region of the second bent portion 1522 connected to the second planar portion 1521. The angled arrangement of the second bent portion 1522 and the second planar portion 1521 may refer to an angled arrangement between the third region 1522A and the second planar portion 1521. For example, the third region 1522A and the second planar portion 1521 may be located on different planes, such that an angle is formed between the plane where the third region 1522A is located and the plane where the second planar portion 1521 is located. The fourth region 1522B may be the region of the second bent portion 1522 away from the second planar portion 1521. The fourth region 1522B may be arranged at an angle to 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 not be parallel to the plane where the second planar portion 1521 is located. It is only necessary that there is an angle between the fourth region 1522B and the third region 1522A.

[0084] When the second metal bracket 152 is connected to the non-metal bracket, the second bent portion 1522 can be embedded in the non-metal bracket 130. For example, the second metal bracket 152 and the non-metal bracket 130 can be formed by an injection molding process, so that the second metal bracket 152 is connected to the non-metal bracket 130 via the second bent portion 1522. The second metal bracket 152 includes the second bent portion 1522, which can make the connection between the second metal bracket 152 and the non-metal bracket 130 more stable, making it difficult for the two to separate from each other, and enhancing the structural strength of the second metal bracket 152 and the non-metal bracket.

[0085] In the second metal bracket 152 shown in Figure 8, the fourth region 1522B can extend from the end of the third region 1522A away from the second planar portion 1521 along the negative direction of the z-axis. The fourth region 1522B can also extend along the positive direction of the z-axis, or can also extend at an angle to the z-axis.

[0086] In some embodiments, the size of the second metal bracket 152 along the second direction can be 3 to 5 times the size of the second planar portion 1521 along the second direction. For the second metal bracket 152 structure shown in FIG8 , similar to the first metal bracket 151, the size of the second metal bracket 152 along the second direction can be the maximum distance between the second planar portion 1521 and the fourth region 1522B in the second direction. The size of the second planar portion 1521 along the second direction can also be referred to as the thickness of the second planar portion 1521, or the thickness of the second metal bracket 152. The thickness of the third region 1522A and the fourth region 1522B can be the same as the thickness of the second planar portion 1521. The size of the second metal bracket 152 along the second direction can be the same as or different from the size of the first metal bracket 151 along the second direction. The size of the second planar portion 1521 along the second direction can be the same as or different from the size of the first planar portion 1511 along the second direction.

[0087] FIG9 is a schematic diagram of the structure of another metal bracket provided in an embodiment of the present application. For the first metal bracket 151, the first planar portion 1511 and the first bent portion 1512 can also be located on the same plane, and the first planar portion 1511 and the first bent portion 1512 can be in a linear structure as shown in the figure, wherein the first planar portion 1511 can extend along the y-axis direction shown in the figure, and the first bent portion 1512 can extend along the z-axis direction shown in the figure, so that the first planar portion 1511 and the first bent portion 1512 are arranged at an angle. Similar to the metal bracket described in FIG8 , the first bent portion 1512 shown in FIG9 can be embedded in the non-metallic bracket 130, and the first metal bracket 151 can be connected to the non-metallic bracket 130 through the first bent portion 1512, so that the connection between the first metal bracket 151 and the non-metallic bracket 130 can be more stable and not easily detached.

[0088] The second planar portion 1521 and the second bent 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 bent portion 1522 can be linear. The second planar portion 1521 can extend along the y-axis shown in the figure, and the second bent portion 1522 can extend along the z-axis shown in the figure, so that the second planar portion 1521 and the second bent portion 1522 are arranged at an angle. The second metal bracket 152 can be connected to the non-metallic bracket via the second bent portion 1522, thereby making the connection between the second metal bracket 152 and the non-metallic bracket 130 more stable and less likely to become detached.

[0089] When the first metal bracket 151 and the second metal bracket 152 are integrally formed into a planar structure, the dimensions of the first metal bracket 151 and the second metal bracket 152 along the second direction are respectively the same as the dimensions of the first planar portion 1511 and the second planar portion 1521 along the second direction. The dimensions of the first metal bracket 151 and the second metal bracket 152 along the second direction may be the same as or different from each other.

[0090] It should be noted that the dotted lines in FIG8 and FIG9 are only for illustrating the positions of the planar portion and the bent portion of the metal bracket, and should not limit the structure of the metal bracket itself.

[0091] In some embodiments, the material of the first metal bracket 151 and / or the second metal bracket 152 can be steel or copper alloy. For example, the material of the first metal bracket 151 and / or the second metal bracket 152 can be 301 stainless steel, 304 stainless steel, or 316 stainless steel, where 301, 304, and 316 can be steel grades. Alternatively, the material of the first metal bracket 151 and / or the second metal bracket 152 can also be nickel silver or other materials. The material of the first metal bracket 151 and / or the second metal bracket 152 being steel or copper alloy can make the first metal bracket 151 and the second metal bracket 152 have high strength and good plasticity, which facilitates 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, the first metal bracket 151 and the second metal bracket 152 shown in FIG8 can be formed from a planar metal sheet that is bent along a predetermined position, so that at least a portion of the structure of the first metal bracket 151 and the second metal bracket 152 is not coplanar with the remaining portion and has a height in the second direction. Furthermore, when the first metal bracket 151 and the second metal bracket 152 are connected to the non-metallic bracket 130, they are not easily separated from the non-metallic bracket 130.

[0092] As described above, the first metal bracket 151 and the second metal bracket 152 can be connected to the non-metal bracket 130 via the first bent portion 1512 and the second bent portion 1522, respectively. Accordingly, as shown in FIG10 , the non-metal bracket 130 can include a main portion 131 and a protruding portion 132. The main portion 131 can be linear, and the side of the main portion 131 away from the first button 111 can include one or more grooves (not shown in the figure) to accommodate the FPC 170. The protruding portion 132 can be provided on one side of the main portion 131 along the z-axis direction. The number of the protruding portions 132 can be two, for example, including the protruding portions 132A and 132B shown in the figure. Among them, the protruding part 132A can be connected to the first metal bracket 151, and the protruding part 132B can be connected to the second metal bracket 152. The structure of the fixed connection between the non-metal bracket 130 and the first metal bracket 151 and the second metal bracket 152 can be seen in the overall structure schematic diagram of the key bracket described in Figure 11 or the cross-sectional structure schematic diagram of the key bracket along the xy plane shown in Figure 12, wherein the circles are respectively enlarged views of the cross-sectional structure of the connection between the first metal bracket 151 and the non-metal bracket 130, and enlarged views of the cross-sectional structure of the connection between the second metal bracket 152 and the non-metal bracket 130. For example, the first bent portion 1511 and the second bent portion 1512 can be respectively embedded in the protruding portions 132A and 132B through an injection molding process. The dimension of the protruding portion 132A along the x-axis can be larger than the dimension of the first metal bracket 151 along the x-axis, so that the entire first bent portion 1512 can be disposed within the protruding portion 132A. The dimension of the protruding portion 132B along the x-axis can be larger than the dimension of the second metal bracket 152 along the x-axis, so that the entire second bent portion 1522 can be disposed within the protruding portion 132B, thereby respectively achieving connection between the first metal bracket 151 and the second metal bracket 152 and the non-metallic bracket 130. Furthermore, 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 can be parallel to the second planar portion 1521, and can be parallel to the main planes of the protruding portions 132A and 132B.

[0093] When the first metal bracket 151, the second metal bracket 152 and the non-metal bracket 130 are arranged in a key assembly or an electronic device, the ends of the protruding parts 132A and 132B away from the main part 131 can be arranged in the groove of the middle frame (not shown in the figure) to support the non-metal bracket 130, and enable the first planar part 1511 and the second planar part 1522 to be located on the through hole 1211 and the through hole 1221 respectively, to limit the displacement of the first hanging ear 1113A and the second hanging ear 1123B along the negative direction of the x-axis.

[0094] Continuing with the cross-sectional structure shown in FIG. 4 , when the first metal bracket 151 is disposed in the electronic device, at least a portion of the first metal bracket 151 can be disposed on the through-hole 1211. In other words, the projection of the first metal bracket 151 along the second direction can at least partially overlap with the through-hole 1211. Furthermore, at least a portion of the first metal bracket 151 can be disposed between the first hanging ear 1113A and the first antenna 121 along the second direction, and the projection of the first metal bracket 151 along the second direction at least partially overlaps with the projection of the first hanging ear 1113A along the second direction. Thus, movement of the first hanging ear 1113A along the negative x-axis can be blocked by the first metal bracket 151, thereby preventing the first button 111 from falling out of the through-hole 1211 and separating from the electronic device during use. Exemplarily, for the first metal bracket 151 shown in Figure 8 or 9, the end of the first planar portion 1511 can be set on the through hole 1211, or in other words, at least a partial structure of the first planar portion 1511 away from the first bent portion 1512 can be set on the through hole 1211, and this partial structure can be set between the first antenna 121 and the first hanging ear 1113A, so that the movement of the first hanging ear 1113A along the negative direction of the x-axis can be blocked by this partial structure.

[0095] Similarly, when the second metal bracket 152 is disposed in the electronic device, at least a portion of the second metal bracket 152 can be disposed on the through-hole 1221, or in other words, the projection of the second metal bracket 152 along the second direction at least partially overlaps with the through-hole 1221. Furthermore, at least a portion of the second metal bracket 152 can be disposed along the second direction between the second hanging ear 1123B and the second antenna 122, and the projection of the second metal bracket 152 along the second direction at least partially overlaps with the projection of the second hanging ear 1123B along the second direction. Thus, the movement of the second hanging ear 1123B along the negative x-axis can be blocked by the second metal bracket 152, thereby preventing the second button 112 from falling out of the through-hole 1221 and separating from the electronic device during use. For the second metal bracket 152 shown in Figure 8 or 9, the end of the second planar portion 1521 can be set on the through hole 1221, or in other words, at least a partial structure of the second planar portion 1521 away from the second bent portion 1522 can be set on the through hole 1221, and this partial structure can be set between the second antenna 122 and the second hanging ear 1123B, so that the movement of the first hanging ear 1123B along the negative direction of the x-axis can be blocked by this partial structure.

[0096] It should be noted that, in the button assembly shown in Figure 4, the first hanging ear 1113B is connected to the first antenna 121, and the first hanging ear 1113A is connected to the first metal bracket 151, that is, the projection of the first hanging ear 1113B along the second direction at least partially overlaps with the projection of the first antenna 121 along the second direction, and the projection of the first hanging ear 1113A along the second direction at least partially overlaps with the projection of the first metal bracket 151 along the second direction, so that the movement of the first hanging ear 1113B along the negative direction of the illustrated x-axis can be blocked by the middle frame 110, and the movement of the first hanging ear 1113A along the negative direction of the x-axis can be blocked by the first metal bracket 151. In the embodiment provided in the present application, the first hanging ear 1113A may be connected to the first antenna 121, and the first hanging ear 1113B may be connected to the first metal bracket 151. That is, the first metal bracket 151 may also be set on the through hole 1212, and the projection of the first hanging ear 1113A along the second direction may at least partially overlap with the projection of the first antenna 121 along the second direction, and the projection of the first hanging ear 1113B along the second direction may at least partially overlap with the projection of the first metal bracket 151 along the second direction, so that the movement of the first hanging ear 1113A along the negative direction of the illustrated x-axis can be blocked by the first antenna 121, and the movement of the first hanging ear 1113B along the negative direction of the illustrated x-axis can be blocked by the first metal bracket 151. Similar to the structure of the first button 111 and the first metal bracket 151, the second metal bracket 152 can be set at the end where the second hanging ear 1123B is located and connected to the second hanging ear 1123B, or it can be set at the end where the second hanging ear 1123A is located and connected to the second hanging ear 1123A, which will not be repeated here.

[0097] Continuing with the structure shown in FIG. 3 or FIG. 4 , the button assembly may further include a circuit board 170, which may be an FPC. The circuit board 170 may be disposed on a side of the first antenna 121 away from the first button body 1111. The side of the circuit board 170 near the first button 111 may include a trigger switch. When the first button 111 and the second button 112 are pressed, the trigger switch may be triggered to implement different functions of the electronic device.

[0098] Specifically, when the first button 111 is a volume button, the first button 111 may include a first trigger portion 1114. The number of the first trigger portions 1114 may be two, for example, a first trigger portion 1114A and a first trigger portion 1114B, as shown in FIG5(a). The first trigger portions 1114A and 1114B may be arranged along a first direction and may be disposed on the same side of the first button body 1111 as the first connecting column 1112. The first trigger portions 1114A and 1114B may have a columnar structure as shown. Accordingly, the first antenna 121 may include through holes 1213 and 1214. As shown in FIG7, the positions of the through holes 1213 and 1214 may correspond to the positions of the first trigger portion 1114A and the first trigger portion 1114B, respectively, and may correspond to the positions of the trigger switch 161 and the trigger switch 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 portion of the first trigger portion 1114A can be accommodated in the through hole 1213, and at least a portion of the first trigger portion 1114B can be accommodated in the through hole 1214. Furthermore, when the end of the first button 111 away from the second button 112 is pressed, the end of the first button 111 away from the second button 112 can be displaced along the positive x-axis. Accordingly, the first trigger portion 1114A can be displaced along the positive x-axis within the through hole 1213 and contact the trigger switch 161, triggering a corresponding function, such as increasing the volume. Similarly, when the end of the first button 111 close to the second button 112 is pressed, the end of the first button close to the second button 112 can be displaced along the positive direction of the x-axis, and the trigger part 1114B can be displaced along the positive direction of the x-axis in the through hole 1214 and contact the trigger switch 162 to trigger the corresponding function, such as reducing the volume.

[0099] When the second button 112 is a power button, the second button 112 may include a second trigger portion 1124. The number of the second trigger portion 1124 may be one. As shown in FIG6 , the trigger portion 1124 may be disposed between the second ears 1123A and 1123B, for example, in the middle of the second button body 1121. The trigger portion 1124 may be disposed on the same side of the second button body 1121 as the second connecting column 1122. The trigger portion 1124 may be a columnar structure. Accordingly, the second antenna 122 may include a through hole 1223. As shown in FIG8 , the position of the through hole 1223 may correspond to the position of the trigger portion 1124, and the radial dimension of the through hole 1223 may be greater than or equal to the radial dimension of the trigger portion 1124. When the second button 112 is pressed, at least a portion of the second button 112 can be displaced along the positive direction of the x-axis, and at least a portion of the trigger portion 1124 can pass through the through hole 1223, contact the trigger switch 163, and trigger the corresponding function, such as turning the screen on or off.

[0100] The first button 111 may further include a foam 1115 , which may be disposed on the same side of the first button 111 as the first connecting column 1112 and located at the center of the first button 111 . The foam 1115 may be used to maintain the balance of the first button 111 .

[0101] An embodiment of the present application also provides a method for manufacturing a key bracket, which can be used to manufacture the above-mentioned first metal bracket, second metal bracket and non-metal bracket. The method may include steps S1301 to S1303, as shown in Figure 13.

[0102] S1301, manufacturing a metal bracket, wherein the metal bracket includes a first metal bracket, a second metal bracket and a metal connecting material, wherein at least a portion of the metal connecting material is disposed between the first metal bracket and the second metal bracket.

[0103] S1302, a non-metallic bracket is manufactured by an injection molding process, and a first metal bracket and a second metal bracket are respectively connected to the non-metallic bracket.

[0104] S1303, remove metal connecting materials.

[0105] For step S1301, the structures of the first metal bracket 151, the second metal bracket 152, and the metal connecting material 153 can be seen in the bracket structure schematic diagram shown in Figure 14. The metal connecting material 153 can include a first portion 1531 and a second portion 1532. The first portion 1531 can be in a strip-shaped structure as shown in the figure. The number of second portions 1532 can be two, and each second portion 1532 can be a protrusion on the first portion 1531. The two second portions 1532 can be connected to the first metal bracket 151 and the second metal bracket 152, respectively. The first metal bracket 151, the second metal bracket 152, and the metal connecting material 153 can be an integrally formed structure, for example, by a casting or forging process.

[0106] In some embodiments, a groove 1541 may be provided between the metal link 153 and the first metal bracket 151, and a groove 1542 may be provided between the metal link 153 and the second metal bracket 152. The grooves 1541 and 1542 may be formed by a process such as cutting. The grooves 1541 and 1542 may be used to facilitate disconnection of the metal link 153 from the first metal bracket 151 and the second metal bracket 152 when the first metal bracket 151 and the second metal bracket 152 are assembled into an electronic device.

[0107] Regarding step S1302, when the non-metallic bracket is manufactured using an injection molding process, a molten non-metal can be injected into the mold. The molten non-metal can be, for example, a molten resin, which is cooled to form the non-metallic bracket. During the injection molding process, the first metal bracket and the second metal bracket can be embedded in the preset positions of the mold so that after the non-metallic melt is cooled and formed, the first metal bracket and the second metal bracket can be fixedly connected to it. Then, after demolding, the structure of the key bracket shown in Figure 14 can be obtained. A metal connecting material is provided between the first metal bracket and the second metal bracket to prevent relative displacement between the first metal bracket and the second metal bracket during the injection molding process due to the push of the injected non-metallic melt.

[0108] For step S1303, after the non-metallic bracket is cooled and formed, the first metal bracket and the second metal bracket can be stably connected to the non-metallic bracket, and then the metal connecting material 153 can be removed by breaking or cutting along the grooves 1541 and 1542 in Figure 14 to obtain the button bracket shown in Figure 11.
