Description

Technical Field

[0001] This disclosure relates to the field of electronic technology, and in particular to an antenna bracket and electronic device. Background Technology

[0002] With a plethora of mobile phone models on the market, consumers are increasingly demanding thinner and lighter phones. Therefore, reducing the thickness of mobile phone products and achieving a thinner and lighter internal structure has become a pressing issue.

[0003] Currently, the antenna brackets inside mobile phones are usually made of pure plastic through injection molding, or with only a small amount of metal incorporated into the plastic. In this case, in order to ensure the yield rate of the plastic antenna brackets, the design thickness of the antenna brackets is usually relatively large, which will lead to an increase in the thickness of electronic devices, failing to meet consumers' demand for thinner and lighter electronic devices.

[0052] The accompanying drawings have illustrated specific embodiments of this disclosure, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0053] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0054] This disclosure provides an antenna bracket, such as... Figure 1 As shown, the antenna support includes a metal part 1 and a plastic part 2. The metal part 1 includes an exposed adapter area 11 and an insulating adapter area 12. The exposed adapter area 11 occupies half or more of the surface of the antenna support. The insulating adapter area 12 is at least partially covered by the plastic part 2 from the top and bottom sides. Figure 1 The shaded area is the exposed adapter area 11, which is not covered by the plastic part 2, while the insulating adapter area 12 is generally covered by the plastic part 2, that is, the insulating adapter area 12 is covered by the plastic part 2 at least from the front or the back.

[0055] It should be understood that the metal part 1 does not necessarily include only the exposed adapter area 11 and the insulating adapter area 12, but may also include other areas and structures. However, relatively speaking, the exposed adapter area 11 and the insulating adapter area 12 already occupy the majority of the metal part 1.

[0056] Taking a mobile phone as an example, the antenna bracket can be located between the motherboard and the battery cover. An NFC (Near Field Communication) antenna can be connected to the side of the antenna bracket facing the battery cover; this antenna bracket can be used to fix the position of the NFC antenna. The NFC antenna can contact the exposed adapter area 11 and connect to the motherboard through clearance holes on the antenna bracket.

[0057] With the thickness of the phone and the NFC antenna already determined, the installation space for the antenna bracket is extremely limited. For example, due to space constraints in the thickness direction (Z-axis) of the phone, the reserved thickness space for the NFC antenna and antenna bracket may only be 0.5mm, and the NFC antenna itself requires an additional 0.25mm of thickness space. Therefore, the usable thickness space for the antenna bracket is only 0.25mm. In this situation, for antenna brackets with small thicknesses, if large-area plastic or pure plastic injection molding is used, the risk of defects such as insufficient glue and trapped air increases significantly, leading to reduced production capacity and yield of the antenna bracket.

[0058] The antenna bracket provided in this disclosure uses a large area of ​​metal part 1 as the main body of the antenna bracket. The thickness of the antenna bracket can be effectively controlled by the exposed adapter area 11 in the metal part 1. The insulating adapter area 12 in the antenna bracket is at least partially covered by the plastic part 2, thereby effectively improving the bonding performance between the metal part 1 and the plastic part 2.

[0059] Furthermore, using a metal part 1 in the antenna bracket can effectively avoid defects such as insufficient glue and trapped air during the injection molding of the plastic part 2, thereby improving the production yield of the antenna bracket; and the metal part 1 can also increase the strength and hardness of the antenna bracket, thereby improving the structural reliability of the antenna bracket.

[0060] Optionally, the metal part 1 can be formed by stamping a metal sheet of uniform thickness. In specific embodiments, the metal sheet is preferably a steel sheet. In other embodiments, the metal sheet can also be made of other materials, such as aluminum, copper, or alloy plates. By stamping, a portion of the metal sheet is bent and deformed in the thickness direction to form a raised or sunken area that is parallel to the flat area of ​​the metal sheet and rises or sinks relative to the flat area in the thickness direction. The exposed adapter area 11 is located on the flat area where no significant deformation has occurred, while most of the insulating adapter area 12 is located on the raised or sunken area.

[0061] The exposed adapter area 11 can be located in the central part of the metal part 1. The location within the electronic device housing corresponding to the exposed adapter area 11 generally has a small reserved installation space for the antenna bracket, and these locations have little impact on antenna performance. Therefore, the exposed adapter areas 11 at these locations do not need to be covered by the plastic part 2. However, the location of the insulating adapter area 21 within the electronic device housing has a larger reserved installation space, requiring the plastic part 2 to fill the installation gaps to ensure the stability of the antenna bracket installation. Furthermore, the location of the insulating adapter area 21 has a greater impact on antenna performance; covering it with the plastic part 2 can effectively reduce the impact of the metal part 1 on antenna performance.

[0062] To improve the bonding performance between the metal part 1 and the plastic part 2, a portion of the flat area may also be covered by the plastic part 2. That is, the insulating adapter area 12 may include a portion of the flat area (the portion of the insulating adapter area 12 adjacent to the exposed adapter area 11). However, due to the limitation of the antenna bracket installation space, a portion of the raised area may not be covered by the plastic part 2. Figure 6 The diagram shown is a front view of the rear structure of the metal part 1. Figure 6 For example, a portion of the raised area located at the upper right of the metal part 1 can rise relative to the exposed fitting area 11, and this raised area is not covered by the plastic part 2. The remaining portion of the raised area can sink relative to the exposed fitting area 11, and this sinking area is basically covered by the plastic part 2.

[0063] like Figure 1 As shown, the insulating adapter region 12 may further include multiple sub-regions recessed relative to the exposed adapter region 11, each sub-region being independent of the others. Each recessed sub-region may be located at the edge of the exposed adapter region 11, thus surrounding the exposed adapter region 11 from different positions. The shape of some sub-regions in the insulating adapter region 12 may match the shape of multiple BTB (Board-to-Board) connectors mounted on the motherboard, allowing the insulating adapter region 12 to crimp the BTB connectors during assembly. Another portion of the sub-regions in the insulating adapter region 12 may have bolt holes for securing the antenna bracket and grounding. The plane containing each sub-region in the insulating adapter region 12 may be parallel to the plane containing the exposed adapter region 11 to ensure sufficient crimping area or bolt mounting area between each sub-region and its corresponding BTB connector.

[0064] In this disclosure, for ease of explanation, the side of the metal part 1 closest to the battery cover is considered the back side of the metal part 1, and the side closest to the motherboard is considered the front side of the metal part 1. The direction of the metal part 1 closest to the battery cover is considered upward, and the direction of the metal part 1 closest to the motherboard is considered downward.

[0065] Optionally, the exposed adapter area 11 has a uniform thickness and flat surfaces on both sides, and the exposed adapter area 11 can occupy 60% or more of the surface of the antenna support. For example... Figure 1-3 As shown, the exposed adapter area 11, which accounts for most of the antenna bracket, is not covered by the plastic part 2, thereby effectively controlling the thickness of the main body of the antenna bracket. The thickness of the insulating adapter area 12 in the metal part 1 is also less than that of a traditional pure plastic antenna bracket. This is because the large area of ​​the metal part 1 used in the antenna bracket effectively reduces the coverage area of ​​the plastic part 2, allowing for the injection molding of a thinner plastic part 2 in a smaller area without worrying about the production yield of the antenna bracket.

[0066] The antenna bracket provided in this disclosure uses a large-area metal part 1 as the main body of the antenna bracket, which effectively reduces the thickness of the antenna bracket while ensuring its reliability. However, the area of ​​the plastic part 2 covering the metal part 1 is small, and the thickness of the plastic part 2 is also relatively thin, which makes it easy for the metal part 1 and the plastic part to peel off. To solve this problem, the antenna bracket provided in this disclosure also has at least one adhesive-coating structure, which includes at least one of the following: adhesive-coated through hole 3, slot 4, fin 5, and protrusion 6.

[0067] Optionally, such as Figure 1 As shown, the metal part 1 may have multiple coated through holes 3, and the plastic part 2 may have multiple protrusions 21. Each protrusion 21 can mate with one coated through hole 3, and the protrusion 21 is located in each coated through hole 3. That is, each coated through hole 3 is filled with plastic, so that the coated through hole 3 can connect the plastic on the upper and lower sides of the insulating adapter region 12. The shapes and sizes of the multiple coated through holes 3 may not be the same. The plastic part 2 and the coated through holes 3 can interlock in the thickness direction, thereby enhancing the bonding performance between the metal part 1 and the plastic part 2.

[0068] Optionally, at least one of the sidewalls of the coated through-hole 3 may be chamfered. That is, the coated through-hole 3 may include a chamfered through-hole. By chamfering the coated through-hole 3, the plastic part 2 and the coated through-hole 3 can interlock in the thickness direction, thereby enhancing the bonding performance between the metal part 1 and the plastic part 2.

[0069] Combination Figure 2 and Figure 3 It can be seen that the areas covered by the plastic part 2 on the back and front of the metal part 1 are different, and further combined Figure 1 It can be seen that the thickness of the plastic portion 2 covering different locations of the metal portion 1 varies. In a specific implementation, the chamfered through-hole can be present at the location where the plastic portion 2 is thinner, so as to connect the plastic portions on opposite sides of the metal portion 1 and improve the bonding performance between the metal portion 1 and the plastic portion 2.

[0070] Optionally, such as Figure 4 Region B in Figure 7 As shown, at least two coated through holes 3 have opposite chamfer directions. In specific implementations, the chamfer direction of the coated through hole 3 is related to the thickness of the plastic portion 2 on both sides of the coated through hole 3. Exemplarily, the coated through hole 3 may include a first chamfered through hole 32 and a second chamfered through hole 33. Both the first chamfered through hole 32 and the second chamfered through hole 33 may have a 45° chamfer. Because the chamfer directions of the first chamfered through hole 32 and the second chamfered through hole 33 are opposite, the metal portion 1 can be glued from both the back and front sides, further improving the bonding performance between the metal portion 1 and the plastic portion 2.

[0071] At the first chamfered through-hole 32, the thickness of the plastic part 2 on the back side of the metal part 1 is greater than the thickness of the plastic part 2 on the front side of the metal part 1. Therefore, the first chamfered through-hole 32 has a chamfer facing the front side of the metal part 1, that is, the diameter of the first chamfered through-hole 32 gradually increases from the back side to the front side of the metal part 1, so as to increase the coating area of ​​the plastic part 2 on the front side of the metal part 1.

[0072] At the second chamfered through-hole 33, the thickness of the plastic portion 2 on the back side of the metal portion 1 is less than the thickness of the plastic portion 2 on the front side of the metal portion 1. Therefore, the second chamfered through-hole 33 has a chamfer facing the back side of the metal portion 1, that is, the diameter of the second chamfered through-hole 33 gradually decreases from the back side to the front side of the metal portion 1, so as to increase the coating area of ​​the plastic portion 2 on the back side of the metal portion 1.

[0073] Furthermore, such as Figure 7 and Figure 8 As shown, at least two of the adhesive-coated through holes 3 have different chamfer sizes. In a specific implementation, the adhesive-coated through hole 3 also includes a third chamfered through hole 34, which has a flared opening on one side. Compared to the first chamfered through hole 32 and the second chamfered through hole 33, the chamfer of the third chamfered through hole 34 is larger, in order to further increase the adhesive-coated area at the third chamfered through hole 34.

[0074] In this disclosure, such as Figure 4 As shown in regions A and B, the first chamfered through-hole 32, the second chamfered through-hole 33, and the third chamfered through-hole 34 are all located on the flat insulating adapter region 12. Specifically, the first chamfered through-hole 32 and the second chamfered through-hole 33 can be located at positions where the plastic portion 2 has a relatively large thickness. The third chamfered through-hole 34 can be located at a position where the plastic portion 2 has a relatively small thickness; that is, the thickness of the plastic portion 2 at the location of the third chamfered through-hole 34 is greater than the thickness of the plastic portion 2 at the locations of the first chamfered through-hole 32 and the second chamfered through-hole 33.

[0075] Specifically, such as Figure 1 He Ru Figure 4As shown in region A, the exposed adapter region 11 may have at least one clearance hole 8, the shape of which is adapted to allow the corresponding electronic device to be exposed. A third chamfered through hole 34 may be located near one of the clearance holes 8. Due to the limited mounting space near the clearance hole 8, the third chamfered through hole 34 is located on a flat insulating adapter region 12, and this flat insulating adapter region 12 has a small area, making it easy to peel off the plastic part 2. By increasing the chamfer degree of the third chamfered through hole 34 to form a flared opening, the bonding performance between the metal part 1 and the plastic part 2 is further improved, reducing the risk of plastic peeling off along the edge of the clearance hole 8.

[0076] like Figure 6 and 8 As shown, the third chamfered through-hole 34 has a chamfer facing the back of the metal part 1, meaning the diameter of the second chamfered through-hole 33 gradually decreases from the back to the front of the metal part 1 (but not necessarily reaching the front). Furthermore, when the third chamfered through-hole 34 is stamped into the metal part 1, the metal part 1 near the third chamfered through-hole 34 undergoes downward deformation. Therefore, compared to the first chamfered through-hole 32 and the second chamfered through-hole 33, the third chamfered through-hole 34 is suitable for being located at a position where the thickness of the plastic part 2 is relatively large.

[0077] Optionally, the through-hole 3 may also include a vertical through-hole 31, the sidewall of which may be perpendicular to the exposed mating area 11. The vertical through-hole 31 may be located at a position where the plastic part is thicker, or at a position where chamfering is difficult.

[0078] For example, such as Figure 1 and Figure 6 As shown, the clearance hole 8 may include a circular camera clearance hole, wherein two camera clearance holes arranged longitudinally along the left edge of the metal part 1 have a communicating opening between them, so that the two camera clearance holes can communicate with each other. Figure 1 As shown, the two interconnected camera clearance holes are filled with a thick plastic part 2, and the connecting opening can also serve as the injection port for the plastic part 2.

[0079] To enhance the bonding performance between the plastic part 2 and the metal part 1, such as Figure 6 As shown, the lateral width of the connecting opening is smaller than the aperture of the camera, so that a flat, insulating adapter area 12 between the clearance holes of the two interconnected cameras can form an insertion portion 121. The insertion portion 121 can be located on the side of the connecting opening near the edge of the metal part 1. This insertion portion 121 can be inserted into the plastic part 2 and covered by the plastic part 2.

[0080] Furthermore, the insertion portion 121 may have a plastic-coated through hole 3 so that the plastic portions 2 on opposite sides of the insertion portion 121 can communicate with each other. Figure 6The example shown is a vertical through hole 31 on the extension portion 121. However, in some embodiments, the adhesive-coated through hole 3 on the extension portion 121 can also be any one or more of the first chamfered through hole 32, the second chamfered through hole 33, and the third chamfered through hole 34.

[0081] Optionally, such as Figure 4 As shown in region E, the metal part 1 may further include a transition region 13 that bends relative to the exposed adapter region 11, and the transition region 13 is located between the exposed adapter region 11 and the insulating adapter region 12. Since the area of ​​each recessed sub-region in the insulating adapter region 12 is small, there is a risk of insufficient adhesive in the smaller sub-regions when applying adhesive from one side of the metal part 1 (e.g., the front side of the metal part 1). Therefore, adhesive-coated through-holes 3 can be provided in the transition region 13 to connect the plastic parts 2 on opposite sides of the metal part 1. That is, at least one adhesive-coated through-hole 3 penetrates the transition region 13 in the thickness direction.

[0082] Furthermore, each adhesive-coated through-hole 3 can simultaneously connect the exposed adapter area 11, the transition area 13, and the insulating adapter area 12, so that the transition area 13 can also be covered with the plastic part 2, further improving the bonding performance between the metal part 1 and the plastic part 2.

[0083] Since it is difficult to process the chamfer at the bend transition region 13, the adhesive-coated through hole 3 penetrating the transition region 13 can be a vertical through hole 31. Of course, in other embodiments, the adhesive-coated through hole 3 penetrating the transition region 13 can also be any one or more of the first chamfered through hole 32, the second chamfered through hole 33, and the third chamfered through hole 34.

[0084] Optionally, such as Figure 4 As shown in regions E and F, transition region 13 may have a corner 131, and at least one adhesive-coated through-hole 3 may be located at corner 131. The connection edge between at least one recessed sub-region of insulating adapter region 12 and exposed adapter region 11 has a corner. Exemplarily, when stamping is required to form an adhesive... Figure 4 When bolt holes are drilled in area F, tearing is likely to occur at the corner 131. By providing a rubber-coated through hole 3 at the corner 131, the risk of tearing can be effectively reduced. At the same time, the rubber-coated through hole 3 at the corner 131 can also connect the plastic parts 2 on opposite sides of the metal part 1, improving the bonding performance between the metal part 1 and the plastic part 2.

[0085] Furthermore, the bolt holes provided on the insulating adapter region 12 in this disclosure, in addition to cooperating with bolts to fix the antenna bracket, can also enable grounding of the antenna bracket. By placing the bolt holes on the recessed sub-regions of the insulating adapter region 12 relative to the exposed adapter region 11, sufficient contact can be made between the bolt holes and the grounding point on the motherboard, thereby ensuring the reliability of the antenna bracket grounding. Each recessed sub-region of the insulating adapter region 12 relative to the exposed adapter region 11 may also be provided with at least one adhesive-coated through-hole 3.

[0086] Optionally, such as Figure 4 As shown in regions B, C, and D, some of the multiple adhesive-coated through holes 3 provided on the metal part 1 can be arranged at intervals along the edge of the metal part 1. The plastic part 2 can fill the spaced adhesive-coated through holes 3 from opposite sides of the metal part 1 to prevent the plastic part 2 from peeling off from the edge of the metal part 1. The adhesive-coated through holes 3 at the edge of the metal part 1 can be any one or more of the following: vertical through hole 31, first chamfered through hole 32, second chamfered through hole 33, and third chamfered through hole 34.

[0087] Optionally, such as Figure 4 As shown in regions B and G, at least a portion of the edge of the metal part 1 may have a groove 4, which is covered by the plastic part 2 so that the plastic in the plastic part 2 fills the groove 4. A snap-fit ​​can be formed between the plastic part 2 and the groove 4, thereby improving the bonding performance between the metal part 1 and the plastic part 2. Furthermore, the bottom width of the groove 4 may be greater than the opening width of the groove 4, that is, the groove 4 may be configured as a dovetail groove to further enhance the bonding force between the groove 4 and the plastic part 2.

[0088] Of the plurality of slots 4 provided in this disclosure, some slots 4 are parallel to the exposed mating area 11, and some slots 4 are bent upward or downward relative to the exposed mating area 11. The slots 4 in multiple directions can provide bonding forces in multiple directions to the metal part 1, thereby improving the bonding performance between the metal part 1 and the plastic part 2. The shapes and sizes of the plurality of slots 4 may not be the same.

[0089] In specific implementation, such as Figure 4 As shown in region B, a portion of the edge of the insulating adapter region 12 is a flat area adjacent to the exposed adapter region 11. Here, the plastic part 2 has a relatively large thickness, and the thickness of the plastic part 2 is also relatively uniform on both the upper and lower sides of the insulating adapter region 12. Therefore, multiple slots parallel to the exposed adapter region 11 can be provided at the edge of the insulating adapter region 12 to improve the bonding performance of the metal part 1 and the plastic part 2 in the direction perpendicular to the thickness.

[0090] Optionally, such as Figure 4 and Figure 5As shown in regions C-D and G-K, at least a portion of the edge of the metal part 1 has a flap 5 bent in the thickness direction. The flap 5 includes a first flap 51 and a second flap 52, the first flap 51 being bent downward relative to the exposed adapter region 11, and the second flap 52 being bent upward relative to the exposed adapter region 11.

[0091] In practice, Figure 4 The C and D regions have second flaps 52, which are configured to cooperate with plastic through holes 3. Figure 4 In regions C and D, the thickness of the plastic portion 2 on the front of the metal portion 1 is relatively small. Therefore, the edge of the metal portion 1 can be bent upwards at these locations to enhance the bonding force between the metal portion 1 and the plastic portion 2 in the thickness direction. The degree of bending of the second wing 52 in regions C and D can be different. The degree of bending of the second wing 52 can depend on the thickness of the plastic portion 2 at the corresponding location, and avoids excessive bending of the second wing 52, which would result in the plastic portion 2 on one side of the second wing 52 being too thin.

[0092] Furthermore, such as Figure 4 As shown in regions C and D, the second wing 52 can be used in combination with the adhesive-coated through hole 3, and at least a portion of the adhesive-coated through hole 3 is provided on the second wing 52. That is, the second wing 52 can be provided with the adhesive-coated through hole 3, or the adhesive-coated through hole 3 can penetrate the transition portion connected by the bent second wing 52, and the transition portion connects the second wing 52 and the flat area of ​​the metal part 1 connected thereto.

[0093] Figure 4 The G, H and I regions are configured to cooperate with the slot 4, that is, the slot 4 can be provided on the wing 5 so that the slot 4 bends in different directions relative to the exposed fitting area 11, thereby providing bonding force in multiple directions.

[0094] Specifically, Figure 4 The G region has multiple second winglets 52 with different degrees of bending, and slots 4 can be formed on the second winglets 52. The shapes and sizes of the multiple second winglets 52 can be different.

[0095] Figure 4 The H region has a second wing 52 that bends upward perpendicularly to the metal part 1. This vertically bent second wing 52 can be located at the edge of the camera clearance hole, where the plastic part 2 is relatively thick. The vertically bent second wing 52 can improve the bonding force between the plastic part 2 and the metal part 1 in the direction perpendicular to the thickness, preventing the metal part 1 from moving within the plastic part 2 due to external drag. Furthermore, a groove 4 can be formed on the vertically bent second wing 52, causing it to also bend upward perpendicularly to the metal part 1, thereby improving the bonding force between the plastic part 2 and the metal part 1 in the thickness direction.

[0096] Figure 4 Region I has a first flap 51 that bends downward relative to the exposed fitting region 11, and a groove 4 may be formed on the first flap 51. Since the thickness of the plastic portion 2 in regions G and I is small, the bending degree of the flap 5 in regions G and I can be small, for example, 15°.

[0097] Because the overall thickness of the antenna bracket is relatively small, the thickness of the plastic part 2 covering the metal part 1 is also relatively small, causing the edges and corners of the metal part 1 to easily lift up. Therefore, as... Figure 4 As shown in J and K, the metal part 1 has a first wing 51 at its corner. By bending the corner of the metal part 1 that is prone to warping downwards at a certain angle to insert it into the plastic part 2, the corner of the metal part 1 can be effectively prevented from warping, and the bonding performance between the metal part 1 and the plastic part 2 can be improved.

[0098] Optionally, such as Figure 4 As shown in regions E and L, at least a portion of the edge of the metal part 1 has a protrusion 6, which protrudes on one side and is recessed on the other side in the thickness direction. Furthermore, the protruding sides of at least two protrusions 6 are opposite.

[0099] In a specific implementation, the protrusion 6 may include a first protrusion 61 and a second protrusion 62, wherein the protruding side of the first protrusion 61 faces downward, and the protruding side of the second protrusion 62 faces both downward and upward. Furthermore, the protruding side of the protrusion 6 is not completely covered by the plastic part 2, that is, the highest point of the protruding side of the protrusion 6 protrudes beyond the plastic part 2, thereby preventing the plastic part 2 from peeling off from the edge.

[0100] like Figure 4 As shown in region E, for the smaller sub-region of the insulating adapter region 12, the width and thickness of the plastic portion 2 covering this sub-region are relatively small, making it easy for the plastic portion 2 to peel off from the edge of the insulating adapter region 12. By providing a protrusion 6 at the edge of the insulating adapter region 12, the peeling of the plastic portion 2 can be effectively prevented, thereby improving the bonding performance between the insulating adapter region 12 and the plastic portion 2.

[0101] Furthermore, the protrusion 6 provided on the insulating adapter region 12 is a second protrusion 62, and the highest point of the protrusion side of the second protrusion 62 can be flush with the upper surface of the exposed adapter region 11 to avoid the increase in the thickness of the antenna support due to the protrusion 6.

[0102] Optionally, the side of the protrusion 6 away from the edge of the metal part 1 is adjacent to the glue-coated through hole 3, and the plastic in the part 2 filled at the recessed side of the protrusion 6 and the glue-coated through hole 3 are connected to each other.

[0103] In specific implementation, such as Figure 4As shown by L, a first protrusion 61 can be provided at the edge of the metal part 1. The recessed side of the first protrusion 61 and the plastic filled by the adhesive-coated through hole 3 are connected to each other, increasing the adhesive-coated area and improving the bonding force between the metal part 1 and the plastic part 2 in the direction perpendicular to the thickness. Furthermore, since the edges of the metal part 1, especially the edges with corners, are prone to lifting, providing the adhesive-coated through hole 3 at the edge to connect the plastic parts on the upper and lower sides of the metal part 1 can effectively reduce the risk of lifting.

[0104] The combined structure of the protrusion 61 and the adhesive-coated through hole 3 can also be understood as the sidewall of the adhesive-coated through hole 3 near the edge protruding in the thickness direction to form the protrusion 6. Figure 4 The L in the example is an example of a combination structure of the first protrusion 61 and the adhesive-coated through hole 3 disposed on a flat insulating adapter region 12. Similarly, the combination structure of the first protrusion 61 and the adhesive-coated through hole 3 can also be disposed on a recessed sub-region in the insulating adapter region 12.

[0105] Optionally, the plastic part 2 has a laser-engraved area 7, which is at least partially located on the sidewall of the plastic part 2 in the thickness direction. The laser-engraved area 7 on the plastic part 2 can be used in conjunction with the antenna on the mid-frame to meet the antenna performance requirements of the electronic device. Furthermore, since the antenna bracket provided in this disclosure uses a large-area metal frame as the main body of the antenna bracket, the amount of plastic part 2 used is greatly reduced, which leads to a corresponding reduction in the area on the plastic part 2 available for setting the laser-engraved area 7. In order to ensure the antenna performance of the electronic device, a laser-engraved area 7 is also provided on the sidewall of the plastic part 2 in the thickness direction, so that the laser-engraved area 7 can be set on the front, sidewall, and back of the plastic part 2, thereby effectively expanding the area of ​​the laser-engraved area 7 and realizing efficient utilization of the plastic part 2.

[0106] It should be noted that, in order to avoid the influence of the metal part 1 on the laser engraving area 7, the orthographic projections of the laser engraving area 7 and the metal part 1 do not coincide. That is, the plastic part 2 covers the edge of the metal part 1, and the edge of the plastic part 2 extends outward relative to the edge of the metal part 1, with the laser engraving area 7 located where the plastic part 2 extends beyond the edge of the metal part 1.

[0107] This disclosure also provides an electronic device having the antenna bracket described above. This electronic device may be, for example, a mobile phone, a tablet computer, or a handheld mobile camera device.

[0108] The antenna bracket provided in this disclosure uses a large-area metal part as the main body of the antenna bracket, and the metal part 1 has an exposed adapter area 11 with uniform thickness and flat surfaces on both sides. The thickness of the antenna bracket can be effectively controlled by the exposed adapter area 11, and the structural reliability of the antenna bracket is improved. The insulating adapter area 12 in the antenna bracket is at least partially covered by the plastic part 2, thereby effectively improving the bonding performance between the metal part 1 and the plastic part 2.

[0109] The antenna support provided in this disclosure also has at least one adhesive-coated structure, which includes at least one of an adhesive-coated through-hole 3, a slot 4, a fin 5, and a protrusion 6. By using multiple adhesive-coated structures, the bonding performance between the metal part 1 and the plastic part 2 can be effectively improved, preventing the plastic part 2 from peeling off from the metal part 1.

[0110] The laser-engraved area 7 is located at least partially on the sidewall of the plastic part 2 in the thickness direction, which effectively expands the area of ​​the laser-engraved area 7 and ensures the antenna performance of the electronic device.
