DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In order to make the technical solutions and advantages of the present application clearer, the antenna bracket and electronic equipment will be described in detail in combination with the drawings.

[0052] The antenna bracket is an important component of electronic devices. The antenna bracket is generally arranged between the motherboard of the electronic device and the battery back cover, pressed on the top of the motherboard, and connected to the shell of the electronic device (such as the middle frame of a mobile phone). It also serves as the antenna layout and motherboard protection.

[0053] In the related art, the antenna bracket is mainly composed of a metal frame and LDS plastic. In order to meet the strength requirements, the entire metal frame is made of the same high-strength metal (such as stainless steel), and the density of each part is uniform, which makes the overall weight of the antenna bracket higher and does not meet the current design standards for lightweight electronic equipment.

[0054] In this regard, an embodiment of the present application provides an antenna bracket, wherein a first portion 11 is connected to a second portion 12 and is formed separately, and at least a portion of the first portion 11 and at least a portion of the second portion 12 are metal frames, wherein the density of the metal frame of the second portion 12 is lower than the density of the metal frame of the first portion 11. Compared with the antenna bracket with uniform density made of high-density metal in the related art, the antenna bracket made of two metals with different densities provided in the present application is lighter in weight, reducing the overall weight of the electronic device, and a first reinforcement member 2 is provided on the outside of the second portion 12, which improves the structural strength of the second portion 12, thereby meeting the weight reduction requirements of the antenna bracket while also ensuring the structural strength of the second portion 12.

[0055] In the antenna bracket provided in the embodiment of the present application, the bracket body 1 is divided into two parts, the metal frame of the first part 11 and the metal frame of the second part 12 are two metal frames with different densities, and the density of the metal frame in the second part 12 is reduced. Compared with the antenna bracket with uniform density in the related art, the antenna bracket made of two metals with different densities provided in the present application is lighter in weight, which reduces the overall weight of the electronic device, and a first reinforcement member 2 is arranged on the outside of the second part 12, which improves the structural strength of the second part 12, meets the weight reduction requirements of the antenna bracket, and ensures the structural strength of the second part 12.

[0056] Optionally, the antenna bracket satisfies at least one of the following:

[0057] The density of the metal frame of the second portion 12 is less than or equal to 30% of the density of stainless steel;

[0058] The density of the first reinforcement member 2 is less than 1.12 g / cm 3 ;

[0059] The strength of the metal frame of the second part 12 is greater than 480 MPa.

[0060] In the related art, stainless steel is mainly used to manufacture the metal part of the antenna bracket. In this embodiment, a metal frame with a density less than or equal to 30% of the density of stainless steel is used to reduce the weight of the metal part of the antenna bracket, which helps to achieve lightweight electronic equipment.

[0061] At the same time, the strength of the metal frame of the second part 12 is designed to be greater than 480 MPa to prevent the strength of the metal frame from changing due to changes in manufacturing materials, ensuring that the antenna layout and mainboard load-bearing protection requirements can be met.

[0062] Due to the need for motherboard protection and LDS antenna manufacturing, the relevant technology may wrap soft plastic parts on part of the metal frame of the antenna bracket. To simplify processing, all parts are usually directly wrapped with LDS plastic. However, in this embodiment, according to different needs, the metal frame in the second part where the antenna is not required to be arranged is wrapped with the first reinforcement, and the density of the first reinforcement is less than 1.12g / cm 3 , which is smaller than the density of conventional LDS plastic materials, so the density of the antenna bracket is further reduced.

[0063] Optionally, at least a portion of the second portion 12 is an aluminum alloy frame; and / or, the first reinforcement member 2 is a nylon member.

[0064] Exemplarily, the second portion 12 is a GM55 aluminum alloy frame, and / or the first reinforcement member 2 is a FE150065 nylon member.

[0065] When the second part 12 is a GM55 aluminum alloy frame, the density is reduced by 70% compared to a stainless steel frame. When the first reinforcement member 2 is a FE150065 nylon member, the density is reduced by 30% compared to LDS plastic.

[0066] In order to further reduce the overall weight of the antenna bracket, in some embodiments of the present application, such as Figure 1 As shown, at least one first weight-reducing structure 21 may be provided on the first reinforcement member 2 to reduce the weight of the first reinforcement member 2 as much as possible while ensuring the structural strength of the second portion 12, thereby reducing the overall weight of the antenna bracket.

[0067] In one example, if Figure 1As shown, the first weight-reducing structure 21 is a weight-reducing hole opened on the first reinforcement member 2 , and those skilled in the art can select and adjust the number and position of the weight-reducing holes according to needs.

[0068] like Figure 3 As shown, the first reinforcement member 2 includes a third portion 22 and a fourth portion 23 , wherein the third portion 22 is U-shaped and connected to the first portion 11 and the second portion 12 respectively, and the fourth portion 23 is the portion of the first reinforcement member 2 other than the third portion 22 .

[0069] according to Figure 4 It can be seen that the fourth portion 23 of the first reinforcement member 2 has a larger coverage area and a heavier weight. Figure 1 As shown, the first weight-reducing structure 21 is a plurality of first weight-reducing grooves 211 opened on the fourth portion 23 of the first reinforcement 2 , and the plurality of first weight-reducing grooves 211 are arranged in an array to reduce the weight of the first reinforcement 2 .

[0070] On this basis, if Figure 4 As shown, a plurality of second weight reducing grooves 212 may be provided on the back side of the first reinforcement 2 (i.e., the surface away from the first weight reducing groove 211). The second weight reducing grooves 212 may be staggered with the first weight reducing grooves 211 or may be overlapped to further reduce the weight of the first reinforcement 2.

[0071] The cross-sectional shapes of the first weight-reducing groove 211 and the second weight-reducing groove 212 may be rectangular, circular, elliptical, etc., and those skilled in the art may select and adjust them according to requirements.

[0072] In some embodiments, Figure 1 As shown, the first weight-reducing structure 21 may include at least two of the above-mentioned weight-reducing holes, the first weight-reducing grooves 211 and the second weight-reducing grooves 212 to reduce the weight of the first reinforcement 2 as much as possible.

[0073] In some embodiments of the present application, Figure 2 As shown, the first part 11 may include a connected antenna arrangement part 111 and a connecting part 112, the connecting part 112 is connected to the second part 12, and the material of the connecting part 112 is different from the material of the second part 12; wherein, a plurality of second weight reduction structures 1121 are arranged on the connecting part 112; and / or, a plurality of third weight reduction structures 121 are arranged on the second part 12.

[0074] The connecting portion 112 and the second portion 12 do not have the function of arranging the antenna, so while ensuring the structural strength, a second weight-reducing structure 1121 may be provided on the connecting portion 112 and / or a third weight-reducing structure 121 may be provided on the second portion 12 to further reduce the overall weight of the antenna bracket.

[0075] In one example, if Figure 1 and Figure 2 As shown, the second weight reduction structure 1121 and the third weight reduction structure 121 are through holes, and the shape of the through holes is circular. Those skilled in the art can select and adjust the shape of the through holes according to requirements, for example, they can be rectangular or elliptical.

[0076] Furthermore, the number and arrangement positions of the through holes are not fixed, and those skilled in the art may select and adjust the number and arrangement positions of the through holes according to weight reduction requirements.

[0077] Optionally, the antenna arrangement portion 111 is a LDS plastic bracket.

[0078] LDS antenna is an antenna manufactured by laser direct structuring technology, which usually requires chemical plating during the manufacturing process. The purpose of chemical plating is to form a metal layer with good conductivity on the surface of the antenna to improve the performance of the antenna. The chemical plating solution usually contains metal particles, chemical solvents and other additives, which are used to react with the plastic substrate during the laser direct structuring process to form a conductive pattern.

[0079] However, there are usually acidic components in the electroless plating solution. Aluminum is prone to oxidation reaction in an acidic environment. When the electroless plating solution comes into contact with the aluminum alloy, it will corrode the aluminum alloy components.

[0080] Therefore, the connecting part 112 used to connect the LDS plastic bracket and the aluminum alloy frame cannot be made of aluminum alloy, that is, the material of the connecting part 112 needs to be different from the material of the second part 12 (aluminum alloy), thereby avoiding corrosion during the LDS antenna plating and ensuring its yield.

[0081] In some embodiments, the connection portion 112 is a stainless steel component, or other metal components that are not easily oxidized by the acidic solution (eg, a copper alloy component). Those skilled in the art can select and adjust according to actual needs.

[0082] According to the above embodiment, the second part 12 is an aluminum alloy frame, and is made of a different material from the connecting part 112 . Therefore, during injection molding, the first part 11 and the second part 12 can be injection molded separately.

[0083] In some embodiments of the present application, the connecting portion 112 is detachably connected to the second portion 12, and the connecting portion 112 and the second portion 12 are respectively injection molded and then assembled; and the connecting portion 112 and the second portion 12 are detachably connected, and when the first portion 11 (especially the antenna arrangement portion 111) or the second portion 12 is defective or damaged, they can be disassembled and replaced separately.

[0084] In the above embodiment, the connecting portion 112 and the second portion 12 are two components respectively formed by injection molding. When the connecting portion 112 is assembled with the second portion 12, interference of parts may occur due to insufficient dimensional accuracy of the components and thermal expansion. Therefore, in some embodiments of the present application, such as Figure 5 As shown, the connecting part 112 may include a plate body 1122, and a first connecting structure 1123 and a second connecting structure 1124 arranged on the plate body 1122; there is a gap 3 between the plate body 1122 and the second part 12; the first connecting structure 1123 and the second connecting structure 1124 are arranged at intervals and are respectively connected to the second part 12; wherein the antenna arrangement part 111 is connected to the plate body 1122.

[0085] The antenna bracket provided in the embodiment of the present application, by setting a gap 3 between the plate body 1122 and the second part 12, can cope with possible size changes or accommodate excess size when the connecting part 112 and the second part 12 are assembled, avoid the occurrence of interference, and improve the fault tolerance of the assembly.

[0086] In some embodiments, Figure 6 As shown, the plate body 1122 includes a connecting plate 11221 and an extension section 11222, wherein the two ends of the connecting plate 11221 are respectively connected to the first connecting structure 1123 and the extension section 11222, and the extension section 11222 is a multi-section stepped structure for connecting to the LDS plastic bracket, wherein the multi-section stepped structure extends the contact area between the LDS plastic bracket and the extension section 11222, thereby improving the connection strength between the LDS plastic bracket and the extension section 11222.

[0087] In order to ensure the normal wireless transmission and reception functions of the antenna, and to suppress the electromagnetic interference from the outside or inside, the mobile phone antenna needs to be grounded.

[0088] In some embodiments of the present application, the first connection structure 1123 is superimposed on the second part 12; the connection portion 112 may also include a first grounding structure 1125, which is connected to the first connection structure 1123 and electrically connected to the second part 12 to ground the first part 11.

[0089] The LDS antenna is connected to the connection part 112, and the connection part 112 is electrically connected to the second part 12 through the first grounding structure 1125, thereby achieving the grounding of the LDS antenna. The first grounding structure 1125 can be electrically connected to the second part 12 in a direct or indirect manner.

[0090] In one example, if Figure 7 and Figure 8As shown, the first grounding structure 1125 includes at least one first protrusion 11251, and the first protrusion 11251 protrudes from the first connection structure 1123 toward the surface of the second part 12, and toward the direction close to the second part 12. By providing the protrusion on the first connection structure 1123, it is ensured that when the first connection structure 1123 is connected and assembled with the second part 12, the protrusion can be directly in contact with the second part 12 and always maintain contact, thereby achieving reliable grounding of the LDS antenna.

[0091] In another example, Figure 6 , Figure 7 and Fig. 9 As shown, a first through hole 11231 is opened on the first connecting structure 1123, and a second through hole 122 is opened on the second part 12. The first connecting structure 1123 and the second part 12 are connected by a fastener 1127 passing through the first through hole 11231 and the second through hole 122; the connecting part 112 also includes a second grounding structure 1126, and the second grounding structure 1126 is connected to the second connecting structure 1124 and is electrically connected to the fastener 1127 to ground the first part 11.

[0092] The fastener 1127 in this example not only serves as a connection structure connecting the first connection structure 1123 and the second part 12, but also serves as a conductive structure, and cooperates with the second grounding structure 1126 to indirectly achieve the grounding of the LDS antenna, further improving the grounding reliability.

[0093] In some embodiments, Fig.10 As shown, the fastener 1127 has a limiting structure, which is used to prevent the fastener 1127 from passing through the first through hole 11231 and the second through hole 122; the second grounding structure 1126 includes at least one second protrusion 11261, and the second protrusion 11261 protrudes from the first connecting structure 1123 toward the surface of the limiting structure of the fastener 1127, in a direction close to the fastener 1127.

[0094] Optionally, the fastener 1127 is a screw, and the limiting structure is a nut on the screw. The screw passes through the first through hole 11231 and the second through hole 122 and is connected to the shell of the electronic device (such as the middle frame of a mobile phone), and the nut abuts against the second protrusion 11261 toward the surface of the first through hole 11231. The LDS antenna guides the current to the shell through the second protrusion 11261 and the screw to complete the grounding.

[0095] It should be noted that although the connection and grounding functions can be achieved by only using screws without the second protrusion 11261, there is a risk of the screws floating (the screws are not locked in place) during assembly of the production line, and there is a risk of the screws loosening. Therefore, adding the second protrusion 11261 to cooperate with the screws can also prevent the screws from floating and reduce the risk of the screws loosening.

[0096] In some embodiments of the present application, Fig.11 As shown, the antenna bracket may further include a second reinforcement member 4 , which wraps the second portion 12 to form at least a portion of the edge of the gap 3 .

[0097] Since the first part 11 and the second part 12 are two components respectively injection molded, and there is a gap 3 between the plate body 1122 and the second part 12, the structural strength at the position of the gap 3 is relatively low. When the antenna bracket is subjected to external pressure, it is easy to cause squeezing of the mainboard, resulting in damage to the mainboard, etc. Therefore, a second reinforcement member 4 is additionally provided to reinforce the structural strength of the position where the second part 12 forms the gap 3.

[0098] In addition, the inventor conducted a comparative test on the weight of the antenna bracket provided in the present application and the weight of the antenna bracket in the related art, and the specific data are shown in Table 1:

[0099]

[0100]

[0101] Table 1

[0102] The antenna bracket provided in the embodiment of the present application has the following advantages:

[0103] (1) When the second portion 12 is an aluminum alloy frame and the first reinforcement member 2 is a nylon member, the weight of the antenna bracket is reduced by more than 50% compared to an antenna bracket using a stainless steel frame and an LDS plastic member.

[0104] (2) A detachable antenna bracket is provided for easy assembly and replacement.

[0105] An embodiment of the present application also provides an electronic device, comprising the above-mentioned antenna bracket.

[0106] In the electronic device provided in the embodiment of the present application, the first part 11 is connected to the second part 12 and is formed separately, and at least a part of the first part 11 and at least a part of the second part 12 are metal frames, wherein the density of the metal frame of the second part 12 is lower than the density of the metal frame of the first part 11. Compared with the antenna bracket with uniform density made of high-density metal in the related art, the antenna bracket made of two metals with different densities provided in the present application is lighter, which reduces the overall weight of the electronic device, and a first reinforcement member 2 is arranged on the outside of the second part 12, which improves the structural strength of the second part 12, thereby meeting the weight reduction requirements of the antenna bracket while also ensuring the structural strength of the second part 12.

[0107] In addition, the use of the above-mentioned antenna bracket also reduces the overall weight of the electronic device, ensures the lightweight requirements of the electronic device, improves the portability of the electronic device, and provides users who hold the electronic device for a long time with a better user experience.
