Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and particularly relates to a frame body and an electronic device. Background Art

[0002] With the continuous development of mobile terminals, users' requirements for mobile terminals such as mobile phones are also getting higher and higher. As an important structural component of a mobile terminal, the middle frame of the mobile terminal has become increasingly important in terms of its material. Compared with a plastic middle frame, a metal middle frame has obvious advantages in terms of feel and appearance, and at the same time has better strength reliability, providing a better user experience for users.

[0003] In related technologies, since a metal middle frame is usually processed and formed on the basis of a whole metal plate by Computerized Numerical Control (CNC), and some antenna structures usually need to be processed in the frame during this process. In order to save processing time and limited by the size of the processing tool, the structure of the antenna processed in the frame is usually relatively simple. In this way, the performance of the frame antenna will be restricted to a certain extent. It can be seen that in related technologies, there is a problem that the performance of the frame antenna is relatively poor. Summary of the Invention

[0004] The present application provides a frame body and an electronic device, which are beneficial to improving the antenna performance of the frame antenna.

[0005] In a first aspect, the present application provides a frame body, including a middle plate and a frame. The frame surrounds the middle plate. The middle plate includes a plurality of first connection positions, and the plurality of first connection positions are arranged at intervals along the edge of the middle plate. And the middle plate is fixedly connected to the frame through the plurality of first connection positions;

[0006] The middle plate includes a middle plate body and a conductive cantilever. A gap is formed between the middle plate body and the frame. The conductive cantilever is arranged in the gap. The first end of the conductive cantilever is connected to the middle plate body, and the second end of the conductive cantilever is connected to the frame. The conductive cantilever is electrically connected to the frame to jointly form an antenna radiator.

[0007] In a second aspect, the present application provides an electronic device, including the frame body described in the first aspect.

[0008] In the embodiments of the present application, by arranging a conductive cantilever in the middle plate and making the conductive cantilever electrically connected to the frame, the conductive cantilever can jointly form an antenna radiator with the frame. In this way, it is beneficial to improve the structural complexity of the antenna in the frame body. Compared with the related technologies where only a relatively simple frame antenna structure can be processed in the frame body, it is beneficial to improve the antenna performance of the frame antenna.

[0058] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0059] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0060] Next, in conjunction with the accompanying drawings, a frame and an electronic device provided in the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0061] Please refer to Figures 1 to 49 , the embodiments of the present application provide a frame, including a middle plate 100 and a frame 200. The frame 200 is disposed around the middle plate 100. The middle plate 100 includes a plurality of first connection positions 110. The plurality of first connection positions 110 are arranged at intervals along the edge of the middle plate 100, and the middle plate 100 is fixedly connected to the frame 200 through the plurality of first connection positions 110;

[0062] The middle plate 100 includes a middle plate body 140 and a conductive cantilever 150. A gap is formed between the middle plate body 140 and the frame 200. The conductive cantilever 150 is disposed in the gap. The first end 151 of the conductive cantilever 150 is connected to the middle plate body 140, and the second end 152 of the conductive cantilever 150 is connected to the frame 200. The conductive cantilever 150 is electrically connected to the frame 200 to jointly form an antenna radiator.

[0063] The above frame can be a metal middle frame of an electronic device. The electronic device can be common electronic devices such as a mobile phone, a tablet computer, etc.

[0064] It can be understood that the above middle plate 100, as the inner plate of the metal middle frame, is located inside the electronic device and can be used to carry relevant components inside the electronic device. Correspondingly, the above frame 200 can form the outer frame of the electronic device.

[0065] The above middle plate 100 and frame 200 can be made of metal materials respectively. For example, in some embodiments of the present application, both the middle plate 100 and the frame 200 are made of aluminum alloy.

[0066] The processing techniques of the above middle plate 100 and frame 200 can be different. For example, in some embodiments of the present application, please refer to Figure 3 , the frame 200 can be a frame structure obtained by processing ordinary profile aluminum alloy using CNC processing technology. Please refer to Figure 4 , the middle plate 100 can be a plate body obtained by processing and forming aluminum alloy in a die casting manner.

[0067] After the middle plate 100 and the frame 200 are processed, the middle plate 100 and the frame 200 can be connected and fixed by welding the multiple first connection positions 110 of the middle plate 100 to the corresponding positions of the frame 200, so as to realize the connection between the middle plate 100 and the frame 200. Then, injection molding is performed on the middle plate 100 and the frame 200 connected together to realize the processing and forming of the frame body.

[0068] The above multiple first connection positions 110 can be relatively evenly distributed along the edge positions of the four sides of the middle plate 100. In this way, the four sides of the middle plate 100 can be respectively fixedly connected to the frame 200, so as to improve the connection stability between the middle plate 100 and the frame 200.

[0069] The above conductive cantilever 150 can refer to: a conductive cantilever 150 whose other positions are spaced apart from other conductive regions of the frame body except for the two ends. For example, please refer to Figures 11 - 12 , the first end 151 of the conductive cantilever 150 is fixedly connected to the middle plate body 140, the second end 152 of the conductive cantilever 150 is fixedly connected to the frame 200, and the other positions of the conductive cantilever 150 except for the two ends are spaced apart from the middle plate body 140 and the frame 200 respectively.

[0070] It can be understood that when the frame is applied to an electronic device, the above antenna radiator can be used as the radiator of the relevant antenna. At this time, the above middle plate body 140 can be used as the main ground of the whole machine, and the antenna radiator can be grounded through the first end 151 of the conductive cantilever 150. At this time, the length of the conductive radiator is the sum of the length of the conductive cantilever 150 and the length of the metal segment in the frame 200 that connects the conductive cantilever 150. In this way, it is beneficial to increase the length of the conductive radiator and the complexity of the antenna radiator structure.

[0071] In this embodiment, by providing the conductive cantilever 150 in the middle plate 100 and electrically connecting the conductive cantilever 150 to the frame 200, the conductive cantilever 150 and the frame 200 can jointly form an antenna radiator. In this way, it is beneficial to increase the structural complexity of the antenna in the frame. Compared with the relatively simple frame antenna structure that can only be processed in the frame in the related art, it is beneficial to improve the antenna performance of the frame antenna. In addition, since the middle plate 100 and the frame 200 are connected through a plurality of first connection positions 110, during the processing of the frame, the middle plate 100 and the frame 200 can be processed separately and then connected. Since the middle plate 100 and the frame 200 can be processed and formed separately, only the frame 200 can be processed by CNC, and for the middle plate 100, a processing method with a lower processing cost and faster speed, such as die casting, can be used. Compared with the prior art where the whole frame needs to be processed by CNC, it is beneficial to reduce the cost of the frame.

[0072] Optionally, the frame 200 includes a plurality of second connection positions 210 corresponding to the plurality of first connection positions 110 one by one. Among the first connection position 110 and the corresponding second connection position 210, one is a first limiting hole and the other is a first limiting post, and the first limiting post penetrates through the first limiting hole; the first connection position 110 is fixedly connected to the corresponding second connection position 210.

[0073] In some embodiments of the present application, the plurality of first connection positions 110 can be respectively a plurality of first limiting posts, and the plurality of second connection positions 210 can be respectively a plurality of first limiting holes.

[0074] In some embodiments of the present application, the plurality of first connection positions 110 can be respectively a plurality of first limiting holes, and the plurality of second connection positions 210 can be respectively a plurality of first limiting posts.

[0075] In some embodiments of the present application, among the multiple first connection positions 110, a part of the first connection positions 110 can be first limiting holes, and the other part can be first limiting posts. Correspondingly, among the multiple second connection positions 210, it can also be that a part of the first connection positions 110 are first limiting holes, and the other part are first limiting posts. Specifically, it can be set according to actual needs, and it only needs to satisfy that among a corresponding group of the first connection position 110 and the second connection position 210, one is a first limiting hole and the other is a first limiting post.

[0076] For the convenience of understanding, in the embodiments of the present application, taking the first connection position 110 as the first limiting post and the second connection position 210 as the first limiting hole as an example, the structure of the frame body in the embodiments of the present application will be further explained.

[0077] Among them, the cross-sectional shape and size of the first limiting hole can match the cross-sectional shape and size of the first limiting post. In this way, when the first limiting post penetrates into the corresponding first limiting hole, the outer side wall of the first limiting post can be attached to the inner wall of the first limiting hole to achieve the limiting and positioning functions.

[0078] In the related art, the internal space size of electronic devices is extremely limited, and the size and cost are directly corresponding. Compared with the integrated processing scheme of the frame and the inner plate in the related art, the detachable frame body scheme provided by the embodiments of the present application requires additional multiple welding positions, that is, it is necessary to additionally add multiple groups of the first connection positions 110 and the second connection positions 210 to form multiple welding positions.

[0079] Both the first limiting post and the first limiting hole of the welding position need to occupy space, and the size of this space will directly affect the area of the main and auxiliary boards, the battery capacity, etc. in the electronic device, and this also directly affects the overall cost and price of the whole machine. In the case where the space is occupied, in order to maintain the electrical performance, the cost will increase significantly. At the same time, the reliability of the first limiting post will directly affect the reliability of the antenna electrical connection. If the first limiting post breaks or has microcracks during injection molding or subsequent processing and cannot be detected later, it will directly affect the yield rate of the frame body and thus affect the cost.

[0080] Based on this, please refer to Figures 5 to 7 , in some embodiments of the present application, the cross-sectional shape of the first limiting post can be in a T shape. In this way, compared with using an oval limiting post, the size space required by the limiting post can be reduced, and at the same time, the limiting post can have higher structural strength. For example, please refer to Figure 8, the size space occupied by the left T-shaped structure is a = 1.5 mm, and the size space b occupied by the right runway circular structure is 1.8 mm. At the same time, the cross-sectional size of the limiting post of the T-shaped structure is larger than that of the limiting post of the runway circular structure. And from the perspective of material mechanics, the limiting post of the T-shaped structure also has better structural strength, which ensures the strength after welding and prevents the welding post from cracking due to subsequent processes.

[0081] It should be noted that, in addition to the T-shaped and runway circular shapes, the cross-sectional shape of the first limiting post can also adopt other shapes, and the cross-sectional shapes of the first limiting posts located in different regions of the inner plate can also be different. For example, please refer to Figure 14 and Figure 15 , in some embodiments of the present application, the cross-sectional shape of the first limiting post is mountain-shaped. Compared with the T-shaped scheme, this structure is equivalent to adding two reinforcing rib positions on both sides of the first limiting post, thereby further improving the structural strength of the first limiting post. Another example, please refer to Figure 16 and Figure 17 , in some embodiments of the present application, the cross-sectional shape of the first limiting post is H-shaped. This structure increases the contact area between the first limiting post and the frame 200 and the middle plate 100 respectively, and can improve the structural strength of the connection between the middle plate 100 and the frame 200. At the same time, when the cross-section of the first limiting post is set to be H-shaped, the cantilever in the middle of the H-shaped will be welded simultaneously with both sides during welding, strengthening the welding strength of the solder joints. Another example, please refer to Figure 3 , the shape of the first limiting post located at the corner of the frame body can be an irregular ellipse to adapt to the shape of the corner of the frame body.

[0082] It can be understood that during the assembly process of the frame body, each first limiting post in the middle plate 100 can be respectively inserted into the corresponding first limiting hole in the frame 200 to achieve the positioning and preliminary fixing between the middle plate 100 and the frame 200. Then, the first limiting post and the corresponding first limiting hole can be welded by welding, so that the first limiting post and the first limiting hole are melted under the high temperature brought by the laser and are tightly connected together after cooling.

[0083] In this embodiment, by making the frame 200 include a plurality of second connection bits 210 corresponding to the plurality of first connection bits 110 one by one, among the first connection bit 110 and the corresponding second connection bit 210, one is a first limiting hole and the other is a first limiting post. In this way, during the assembly of the frame body, each first limiting post can be respectively inserted into the corresponding first limiting hole to achieve the positioning and preliminary fixing between the middle plate 100 and the frame 200. In this way, it is possible to prevent the relative movement of the conductive frame body and the frame 200 during the subsequent welding process, thereby facilitating the improvement of the qualification rate of the obtained frame body.

[0084] Optionally, the frame body includes a first protrusion 220 extending toward the side of the middle plate 100. The middle plate 100 is provided with a notch 120 with an opening facing the frame 200. The first protrusion 220 extends into the notch 120. The middle plate 100 further includes a cantilever 130. The cantilever 130 is arranged along the thickness direction of the middle plate 100, and the cantilever 130 straddles the notch 120 and the first protrusion 220.

[0085] Another difference between the frame body provided by the embodiment of the present application and the metal middle frame in the related art is that the frame 200 and the middle plate 100 need to be assembled together first and then welded. And this assembly process is directional, which causes some structural features in some frame bodies to affect the assembly. For example, common T-slot structures, hidden installation structures, etc. in the frame 200 may interfere with the middle plate 100 during the assembly process, resulting in the problem of difficult assembly. If these structures that may cause interference are cancelled, it will cause a loss of the strength of the frame body and an increase in the overall machine cost.

[0086] Among them, the first protrusion 220 may be various structural members that may cause interference between the frame 200 and the middle plate 100 during the assembly process. For example, please refer to Figure 9 and Figure 10 , in some embodiments of the present application, the first protrusion 220 may be an extended branch extending inward from the frame 200. Among them, this extended branch can realize the electrical connection between the frame 200 and the internal circuit, or realize functions such as grounding of the frame 200.

[0087] Please refer to Figure 10 , in some embodiments of the present application, in order to enable the cantilever 130 to avoid the first protrusion 220, the cantilever 130 can be set into an "overpass" - type structure. Please refer to Figure 10 , during the assembly process, it can be along Figure 10The path indicated by the arrow in [description] assembles the frame 200 with the middle plate 100. That is, when assembling the frame 200, first insert the frame 200 obliquely, then translate the frame 200, and finally let the frame 200 fall vertically so that the first limiting post penetrates into the first limiting hole. At the same time, interference between the frame 200 and the middle plate 100 during the assembly process can be avoided.

[0088] In this embodiment, by making the cantilever 130 span across the notch 120 and the first protrusion 220, and the cantilever 130 protruding along the thickness direction of the middle plate 100 to avoid the first protrusion 220. In this way, interference between the frame 200 and the middle plate 100 at the first protrusion 220 can be avoided. At the same time, since the cantilever 130 spans across both sides of the notch 120, the structural strength of the middle plate 100 at the notch 120 can be improved.

[0089] Optionally, please refer to Figure 18 , the conductive cantilever 150 includes a first segment 153, a bent segment 154, and a second segment 155 connected in sequence. The first segment 153 and the second segment 155 are arranged relatively parallel, and there is a gap between the first segment 153 and the second segment 155. One end of the first segment 153 away from the bent segment 154 is the first end 151 of the conductive cantilever 150, and one end of the second segment 155 away from the bent segment 154 is the second end 152 of the conductive cantilever 150.

[0090] Please refer to Figure 18 , in some embodiments of the present application, the conductive cantilever 150 can be folded along the thickness direction of the frame to form a first segment 153, a bent segment 154, and a second segment 155 connected in sequence, that is, the first segment 153 and the second segment 155 are arranged at intervals along the thickness direction of the middle plate 100. The first end 151 of the conductive cantilever 150 can be opposite to the second end 152 of the conductive cantilever 150, or the first end 151 of the conductive cantilever 150 can be offset in position relative to the second end 152 of the conductive cantilever 150.

[0091] Please refer to Figure 32, the conductive cantilever 150 may further include a process connection position 156. During the processing of the middle plate 100, the conductive cantilever 150 can be fixedly connected to the middle plate body 140 through the process connection position 156. In this way, during the processing of the middle plate 100 and the subsequent injection molding process, it can be ensured that the conductive cantilever 150 is connected to the middle plate body 140, preventing the position of the conductive cantilever 150 from shifting relative to the middle plate body 140, and reducing the risk of breakage at the connection between the first end 151 of the conductive cantilever 150 and the middle plate body 140. After completing the injection molding of the housing, the connection between the conductive cantilever 150 and the middle plate body 140 at the process connection position 156 can be removed by CNC, so as to ensure that in the processed housing, the conductive cantilever 150 is only electrically connected to the middle plate body 140 through the first end. Please refer to Figures 26 to 28 , which is a schematic structural diagram of the conductive cantilever 150 after blanking processing. The conductive cantilever 150 is integrally in a "Z" shape and in a "yin-yang" shaped loop in the horizontal projection direction.

[0092] In this embodiment, by making the conductive cantilever 150 include a first segment 153, a bent segment 154, and a second segment 155 connected in sequence, the first segment 153 and the second segment 155 are arranged opposite to each other, and there is a gap between the first segment 153 and the second segment 155. One end of the first segment 153 away from the bent segment 154 is the first end 151 of the conductive cantilever 150, and one end of the second segment 155 away from the bent segment 154 is the second end 152 of the conductive cantilever 150. In this way, it is beneficial to increase the complexity of the structure of the conductive cantilever 150. Compared with the relatively simple antenna structure that can only be processed in the housing in the related art, it is beneficial to improve the antenna performance of the antenna.

[0093] Optionally, the first connection position 110 is provided at the second end 152 of the conductive cantilever 150.

[0094] Please refer to Figure 21 , in Figure 21 the illustrated embodiment, the first connection position 110 at the second end 152 of the conductive cantilever 150 can be a welding groove. Correspondingly, a welding post can be provided at the corresponding position of the frame 200 as the corresponding second connection position 210. During the assembly process, the welding post can be inserted into the welding groove to achieve position positioning, and then, the welding post and the welding groove can be welded together by welding. After completing the above welding process, the frame 200 and the middle plate 100 are already fixed together. Then, it is put into the mold for injection molding to obtain as Figure 24The frame shown. In the semi-finished product form, the conductive cantilever 150 is wrapped inside the plastic. Therefore, on the basis of the semi-finished frame, a blanking CNC process can be added, and in this process, the connecting structure at the process connection position 156 and the plastic on its surface are processed and removed to obtain Figure 25 The structure shown, where the plastic on the surface of the connecting structure at the process connection position 156 includes Figure 25 The plastic at the CNC blanking processing position 300 in Figures 26 to 28 . After the blanking process, the structure of the metal cantilever inside the plastic is as shown in

[0095] It can be understood that the number of the above process connection positions 156 can be greater than 1, and its specific number and setting position can be set according to actual needs. For example, please refer to Figure 30 , in some embodiments of the present application, the number of the process connection positions 156 is 2 to strengthen the structural strength of the metal cantilever during die casting and prevent fracture. The connecting structure at the process connection position 156 will be removed by CNC processing in the final finished product.

[0096] Please refer to Figures 30 to 34 , in some embodiments of the present application, the above conductive cantilever 150 may not be folded. At this time, the conductive cantilever 150 and the frame 200 can jointly form a Z-shaped antenna design form. Please refer to Figure 12 , a first limiting post can be set at the second end 152 of the conductive cantilever 150 as the first connection position 110. Correspondingly, a corresponding first limiting hole can be set on the frame 200. During the assembly process, the first limiting post at the second end 152 of the conductive cantilever 150 can be embedded into the corresponding first limiting hole, and then, the two are welded to combine the conductive cantilever 150 and the frame 200 into a Z-shaped antenna structure. This structural form can enhance the performance of the antenna, greatly increase the length of the antenna on a limited size length to achieve the performance index of the antenna. At the same time, this design does not increase additional materials and costs, and is a performance improvement scheme without cost increase.

[0097] In this embodiment, by providing the first connection position 110 at the second end 152 of the conductive cantilever 150, in this way, the second end 152 of the conductive cantilever 150 can be fixedly connected to the corresponding second connection position 210 on the frame 200 through the first connection position 110, thereby improving the connection stability between the conductive cantilever 150 and the frame 200.

[0098] Optionally, please refer to Figure 33 , the frame further includes a conductive elastic sheet 157, the second end 152 of the conductive cantilever 150 is connected to the conductive elastic sheet 157, and the conductive elastic sheet 157 abuts against the inner wall of the frame 200.

[0099] In Figure 33 the illustrated embodiment, the above-mentioned conductive cantilever 150 is not folded either. In order to achieve the electrical connection between the second end 152 of the conductive cantilever 150 and the frame 200, a conductive elastic sheet 157 can also be connected to the second end 152 of the conductive cantilever 150 by welding, and the conductive elastic sheet 157 is made to abut against the inner wall of the frame 200, thereby forming a stable electrical connection structure. Finally, after the injection molding is completed, the connection structure at the process connection position 156 is cut off by CNC machining to obtain a finished product as shown in Figure 34 the figure. At this time, the middle plate 100 and the frame 200 are integrally connected in a "Z" shape, realizing the functions corresponding to the antenna.

[0100] In addition, Figure 33 the conductive elastic sheet 157 in the illustrated embodiment can also be replaced by other conductive elastic members. For example, it can be replaced by a conductive foam 167 or other forms of elastic sheets, etc.

[0101] In this embodiment, by making the frame further include a conductive elastic sheet 157, the second end 152 of the conductive cantilever 150 is fixedly connected to the conductive elastic sheet 157, and the conductive elastic sheet 157 abuts against the inner wall of the frame 200. In this way, it is beneficial to increase the complexity of the antenna radiator structure, thereby improving the corresponding antenna performance.

[0102] Optionally, in the middle plate body 140 and the frame 200, one includes a first electrical connection area 160, and the other includes a second electrical connection area 170 corresponding to the first electrical connection area 160. The first electrical connection area 160 is provided with a second limit post 161 and a third limit post 162 extending toward the side of the second electrical connection area 170. The second electrical connection area 170 is provided with a second limit hole 171 and a third limit hole 172. The second limit post 161 is inserted into the second limit hole 171, and the third limit post 162 is inserted into the third limit hole 172 to make the first electrical connection area 160 and the second electrical connection area 170 conduct electricity.

[0103] It can be understood that in some embodiments of the present application, the middle plate body 140 can be made to include the first electrical connection area 160, and the frame 200 includes the second electrical connection area 170. At this time, the above-mentioned second limit post 161 and third limit post 162 are two limit posts extending from the side of the middle plate body 140 toward the frame 200. Correspondingly, the second limit hole 171 and the third limit hole 172 are two limit holes opened in the frame 200.

[0104] In some embodiments of the present application, the first electrical connection region 160 and the second electrical connection region 170 are connected by a connecting member, where the connecting member is used to conduct the first electrical connection region 160 and the second electrical connection region 170, or the connecting member is used to relatively separate the first electrical connection region 160 and the second electrical connection region 170.

[0105] In some embodiments of the present application, the second limiting hole 171 and the third limiting hole 172 belong to the first limiting hole, the second limiting post 161 and the third limiting post 162 belong to the first limiting post, the first electrical connection region is located between the first limiting posts or the first limiting holes, the second electrical connection region is located between the first limiting posts or the first limiting holes, and the first electrical connection region and the second electrical connection region are flat plate-like structures parallel to the middle plate.

[0106] In some other embodiments of the present application, the above-mentioned frame 200 may also include the first electrical connection region 160, and the middle plate body 140 includes the second electrical connection region 170. At this time, the above-mentioned second limiting post 161 and the third limiting post 162 are two limiting posts extending from the side of the frame 200 toward the middle plate body 140. Correspondingly, the second limiting hole 171 and the third limiting hole 172 are two limiting holes formed in the middle plate body 140.

[0107] Please refer to Figures 35 to 49 , taking the above-mentioned middle plate body 140 including the first electrical connection region 160 and the frame 200 including the second electrical connection region 170 as an example in some embodiments of the present application, the structure of the frame provided by the embodiments of the present application is further explained.

[0108] Among them, the second limiting post 161 and the third limiting post 162 may be fixedly connected to the second electrical connection region 170 respectively. Specifically, welding can be performed at the connection between the second limiting post 161 and the second limiting hole 171. At the same time, welding is performed at the connection between the third limiting post 162 and the third limiting hole 172.

[0109] Specifically, there are some electrical connection positions between the frame 200 and the middle plate 100 to facilitate the conduction between the antenna structure located in the frame 200 and the internal circuit. The above-mentioned first electrical connection position and the second electrical connection position may be a set of electrical connection positions in the frame that can realize the conduction between the antenna structure in the frame 200 and the internal circuit.

[0110] It can be understood that the first electrical connection region 160 can be electrically connected to relevant circuit structures inside the electronic device, and the second electrical connection region 170 can be electrically connected to relevant antenna structures in the frame. In this way, the antenna structures in the frame can be electrically connected to the circuit structures inside the electronic device through the second electrical connection region 170 and the first electrical connection region 160 in sequence.

[0111] In this embodiment, since the second limiting post 161 and the third limiting post 162 are respectively fixedly connected to the second electrical connection region 170, the second limiting post 161 and the third limiting post 162 can be electrically conducted with the second electrical connection region 170 respectively. Therefore, the first electrical connection region 160 can be electrically conducted with the second electrical connection region 170 at least through the second limiting post 161 and the third limiting post 162, so as to realize the electrical conduction between the first electrical connection region 160 and the second electrical connection region 170.

[0112] Among them, since Figure 35 In the illustrated embodiment, the non-welding positions of the first electrical connection position and the second electrical connection position are directly overlapped in the thickness direction of the frame body. When the sizes of the middle plate 100 and the conductive frame body fluctuate or one side warps up, gaps are likely to be formed between the first electrical connection position and the second electrical connection position in the thickness direction of the frame body, resulting in the problem of "seemingly connected but not actually connected" between the first electrical connection position and the second electrical connection position, making the size of the local resistance in this area uncontrollable, which has an impact on the overall antenna consistency and other electronic stabilities.

[0113] Based on this, in some embodiments of the present application, the first electrical connection region 160 is provided with a first groove 163 with an opening facing the second electrical connection region 170. The first groove 163 is located between the second limiting post 161 and the third limiting post 162. The bottom of the first groove 163 is arc-shaped. The second electrical connection region 170 is provided with a first convex portion 173 protruding toward the first electrical connection region 160. The first convex portion 173 is embedded in the first groove 163, and the first convex portion 173 is interference-fitted and connected to the bottom of the first groove 163, so that the first electrical connection region 160 and the second electrical connection region 170 are electrically conducted.

[0114] It can be understood that when the middle plate body 140 includes the first electrical connection region 160 and the frame 200 includes the second electrical connection region 170, the first groove 163 is located in the middle plate body 140, and the first convex portion 173 is located in the frame 200.

[0115] Correspondingly, when the above-mentioned frame 200 includes a first electrical connection area 160 and the middle plate body 140 includes a second electrical connection area 170, the first protrusion 173 is located on the middle plate body 140, and the first groove 163 is located on the frame 200.

[0116] Please refer to Figure 36 , in some embodiments of the present application, the above-mentioned middle plate body 140 includes a first electrical connection area 160, the frame 200 includes a second electrical connection area 170, and the bottom of the first groove 163 may be an arc surface with a large R angle. Correspondingly, please refer to Figure 38 , the end face of the first protrusion 173 for contacting the bottom of the first groove 163 will not be chamfered, so that the end face of the first protrusion 173 for contacting the bottom of the first groove 163 has a sharp angle. In this way, during assembly, when the first protrusion 173 is inserted into the first groove 163, the first protrusion 173 can be inserted into the first groove 163. At the same time, since the bottom of the first groove 163 is an arc surface, the sharp angle of the first protrusion 173 will interfere with the bottom of the first groove 163. And the strength of the sharp angle of the first protrusion 173 is not high. Under the external force of the assembly jig being pressed, the position where the sharp angle of the first protrusion 173 interferes with the bottom of the first groove 163 is deformed, so that the first protrusion 173 is tightly connected to the first groove 163.

[0117] In this embodiment, since the first groove 163 and the first protrusion 173 are positions where gaps are likely to occur between the first electrical connection area 160 and the second electrical connection area 170, therefore, by opening a first groove 163 with an opening facing the second electrical connection area 170 in the first electrical connection area 160, the first groove 163 is located between the second limiting post 161 and the third limiting post 162, the bottom of the first groove 163 is arc-shaped, and a first protrusion 173 protruding toward the first electrical connection area 160 is provided on the second electrical connection area 170. The first protrusion 173 is embedded in the first groove 163, and the first protrusion 173 is interference-fitted and connected to the bottom of the first groove 163. In this way, the frame provided by the present application can effectively accommodate the problem that the frame 200 and the middle plate 100 cannot be stably electrically connected due to size differences. At the same time, the first groove 163 and the first protrusion 173 can also play a role in limiting to a certain extent, ensuring the position accuracy during welding.

[0118] Optionally, please refer to Figure 39, the first electrical connection area 160 includes bumps 164 protruding towards the second electrical connection area 170, and the bumps 164 are located between the second limiting posts 161 and the third limiting posts 162. The bumps 164 are interference-fitted and connected to the second electrical connection area 170, so that the first electrical connection area 160 and the second electrical connection area 170 are electrically connected.

[0119] It can be understood that when the middle plate body 140 includes the first electrical connection area 160 and the frame 200 includes the second electrical connection area 170, the bumps 164 are located on the middle plate body 140.

[0120] Correspondingly, when the frame 200 includes the first electrical connection area 160 and the middle plate body 140 includes the second electrical connection area 170, the bumps 164 are located on the frame 200.

[0121] Please refer to Figure 39 , in some embodiments of the present application, the middle plate body 140 includes the first electrical connection area 160, the frame 200 includes the second electrical connection area 170, the bumps 164 may be circular bumps 164 provided on the first electrical connection area 160, and the height of the bumps 164 may be about 0.05 mm. Among them, the number and arrangement positions of the bumps 164 can be set according to actual needs.

[0122] In some embodiments of the present application, the bumps 164 may also be provided on the second electrical connection area 170. At this time, the bumps 164 protrude towards the first electrical connection area 160.

[0123] In this embodiment, by making the first electrical connection area 160 include bumps 164 protruding towards the second electrical connection area 170, and the bumps 164 are located between the second limiting posts 161 and the third limiting posts 162, the bumps 164 are interference-fitted and connected to the second electrical connection area 170, so that the first electrical connection area 160 and the second electrical connection area 170 are electrically connected. In this way, after the frame 200 and the middle plate 100 are assembled, the protrusions can interfere with the second electrical connection area 170, thereby realizing a stable electrical connection between the first electrical connection area 160 and the second electrical connection area 170

[0124] Optionally, an insulating plate 165 is provided between the first electrical connection area 160 and the second electrical connection area 170. At least one of the first electrical connection area 160 and the second electrical connection area 170 is fixedly connected to the insulating plate 165, and the insulating plate 165 is located between the second limiting posts 161 and the third limiting posts 162.

[0125] In addition to the requirement for stable electrical connection, in some scenarios, the first electrical connection region 160 and the second electrical connection region 170 may also have a requirement for stable "electrical disconnection". Specifically, in these scenarios, electrical connection may only be required at the second limiting post 161 and the third limiting post 162, and a stable electrical disconnection effect is required for the region between the second limiting post 161 and the third limiting post 162. Based on this, in the embodiments of the present application, an insulating plate 165 is provided between the first electrical connection region 160 and the second electrical connection region 170, at least one of the first electrical connection region 160 and the second electrical connection region 170 is fixedly connected to the insulating plate 165, and the insulating plate 165 is located between the second limiting post 161 and the third limiting post 162. In this way, due to the isolation effect of the insulating plate 165, the region between the second limiting post 161 and the third limiting post 162 can have a stable electrical disconnection effect.

[0126] In some embodiments of the present application, two positioning holes may be provided in the first electrical connection region 160, and two corresponding positioning posts 1651 may be provided in the insulating plate 165. In this way, the positioning posts 1651 can be inserted into the corresponding positioning holes to achieve the fixed connection between the insulating plate 165 and the first electrical connection region 160, and at the same time, the position of the insulating plate 165 can be fixed. Please refer to Figure 42 , during the assembly process, the insulating plate 165 can be assembled to the first electrical connection region 160 first, and then, the normal assembly and welding processes can be carried out. Please refer to Figure 43 , after the assembly is completed, the first electrical connection region 160 and the second electrical connection region 170 do not directly contact, so as to achieve a stable insulating effect, which is beneficial to ensuring the consistency of the products in mass production.

[0127] It can be understood that, in some embodiments of the present application, two positioning holes may also be provided in the second electrical connection region 170, and two corresponding positioning posts 1651 may be provided in the insulating plate 165. In this way, the positioning posts 1651 can be inserted into the corresponding positioning holes to achieve the fixed connection between the insulating plate 165 and the second electrical connection region 170, and at the same time, the position of the insulating plate 165 can be fixed.

[0128] In this embodiment, by providing an insulating plate 165 between the first electrical connection region 160 and the second electrical connection region 170, at least one of the first electrical connection region 160 and the second electrical connection region 170 is fixedly connected to the insulating plate 165, and the insulating plate 165 is located between the second limiting post 161 and the third limiting post 162. Thus, due to the isolation effect of the insulating plate 165, the region between the second limiting post 161 and the third limiting post 162 can have a stable non - electrical connection effect.

[0129] Optionally, the first electrical connection region 160 is provided with a second groove 166 opening towards the second electrical connection region 170. A conductive foam 167 is embedded in the second groove 166, and the conductive foam 167 is compressed between the bottom of the second groove 166 and the second electrical connection region 170 to electrically connect the first electrical connection region 160 and the second electrical connection region 170.

[0130] It can be understood that when the middle plate body 140 includes the first electrical connection region 160 and the frame 200 includes the second electrical connection region 170, the second groove 166 is located in the middle plate body 140.

[0131] Correspondingly, when the frame 200 includes the first electrical connection region 160 and the middle plate body 140 includes the second electrical connection region 170, the second groove 166 is located in the frame 200.

[0132] Please refer to Figure 45 and Figure 46 , in some embodiments of the present application, when the middle plate body 140 includes the first electrical connection region 160 and the frame 200 includes the second electrical connection region 170, a second protrusion 174 corresponding to the first groove 163 can be provided in the second electrical connection region 170. Thus, after assembly, the second protrusion 174 can be embedded in the second groove 166, so that the conductive foam 167 can be compressed between the second protrusion 174 and the bottom of the second groove 166 to achieve a stable electrical connection between the first electrical connection region 160 and the second electrical connection region 170.

[0133] In some embodiments of the present application, the thickness of the conductive foam 167 can be made greater than the depth of the second groove 166. Thus, after assembly, the conductive foam 167 can be compressed between the second electrical connection region 170 and the bottom of the second groove 166 to achieve a stable electrical connection between the first electrical connection region 160 and the second electrical connection region 170.

[0134] In addition, in some embodiments of the present application, the above-mentioned second groove 166 may also be opened in the second electrical connection area 170. At this time, the conductive foam 167 can be compressed between the bottom of the second groove 166 and the first electrical connection area 160 to achieve a stable electrical connection between the first electrical connection area 160 and the second electrical connection area 170.

[0135] In this embodiment, by opening a second groove 166 with an opening facing the second electrical connection area 170 in the first electrical connection area 160, a conductive foam 167 is embedded in the second groove 166, and the conductive foam 167 is compressed between the bottom of the second groove 166 and the second electrical connection area 170, which is beneficial to achieving a stable electrical connection between the first electrical connection area 160 and the second electrical connection area 170.

[0136] Optionally, the first electrical connection area 160 and the second electrical connection area 170 are fixedly connected by a fastener, and the fastener is located between the second limiting post 161 and the third limiting post 162.

[0137] Please refer to Figure 49 , in some embodiments of the present application, the fastener is a screw 169. Specifically, a threaded hole 175 can be opened in the above-mentioned second electrical connection area 170 by means of CNC and tapping, and a corresponding threaded hole position 168 can be formed by tapping in the first electrical connection area 160. As Figures 47 to 49 shown, after assembly, the screw 169 can be inserted into the threaded hole 175 and the threaded hole position 168 to achieve the fixed connection between the first electrical connection area 160 and the second electrical connection area 170 by a fastener.

[0138] After the screw 169 is tightened, the whole is put into an injection mold for injection molding. As Figure 49 shown, after injection molding is completed, the screw is tightly wrapped in the plastic material, and at this time the screw will not loosen, and a very stable electrical connection state can be formed.

[0139] Similarly, in this embodiment, during specific implementation, the screw 169 can also be replaced with other fasteners such as rivets or pins that can connect two pieces of metal to achieve an effect similar to that of the screw 169.

[0140] In this embodiment, by fixedly connecting the first electrical connection area 160 and the second electrical connection area 170 by a fastener, and the fastener is located between the second limiting post 161 and the third limiting post 162, thus, it is beneficial to achieve a stable electrical connection between the first electrical connection area 160 and the second electrical connection area 170.

[0141] An embodiment of the present application further provides an electronic device, and the electronic device includes the housing described in the above embodiment.
