Description

Technical Field

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

[0002] At present, in order to achieve the thinness and beauty of electronic devices, a magnesium alloy (MDA) plastic middle frame (hereinafter referred to as MDA middle frame) is widely used. The two sides of the MDA middle frame are directly connected to the screen and the back panel, making the electronic device appear as a whole in appearance. Among them, the antenna area is provided around the MDA middle frame to realize the in-mold injection molding antenna.

[0003] However, this antenna structure greatly increases the difficulty of mold manufacturing and production of the MDA middle frame. Excessive manufacturing difficulty not only affects the manufacturing cycle and cost, but also poses challenges to the stability of quality.

[0004] Therefore, how to reduce the manufacturing difficulty of the middle frame assembly is a technical problem that needs to be solved urgently. Summary of the invention

[0005] The present application provides a middle frame assembly and an electronic device, which can reduce the difficulty of manufacturing the middle frame assembly.

[0006] In a first aspect, a middle frame assembly is provided. The middle frame assembly includes a middle frame, and two sides of the middle frame are respectively used to connect a display module and a back plate. The middle frame assembly also includes a bracket, and the bracket includes a bending area, and the bending area includes an edge of a main body of the bracket and a bending portion located at the edge of the main body, and the bending portion is bent along a first direction perpendicular to the main body and connected to the middle frame, and the bending area includes a receiving space, and the receiving space is used to receive an antenna module.

[0007] Based on the middle frame assembly provided in the embodiment of the present application, the middle frame assembly includes a middle frame and a bracket. The bracket is provided with a receiving space for receiving the antenna module. Thus, the manufacturing of the middle frame and the manufacturing of the antenna module can be relatively decoupled, and the middle frame assembly has a lower manufacturing difficulty.

[0008] In combination with the first aspect, in certain implementations of the first aspect, the accommodating space includes a first groove, a bottom surface of the first groove is located on a first surface of the main body, and the first surface of the main body is a surface away from the middle frame.

[0009] Based on the middle frame assembly provided in the embodiment of the present application, the antenna module can be arranged in the first groove on the main body of the bracket, so that the connection between the antenna module and the bracket is more stable while avoiding the antenna module occupying too much space.

[0010] In combination with the first aspect, in certain implementations of the first aspect, the bottom surface of the first groove is also located on the first surface of the bending portion, and the first surface of the bending portion is connected to the first surface of the main body.

[0011] Based on the middle frame assembly provided in the embodiment of the present application, the antenna module can be arranged in the first groove of the bracket main body and the bending part, and the bottom of the first groove can be bent, so that the antenna module is more firmly connected to the bracket while avoiding the antenna module occupying too much space.

[0012] In combination with the first aspect, in some implementations of the first aspect, a bend in the accommodating space along the first direction is arc-shaped.

[0013] Based on the middle frame assembly provided in the embodiment of the present application, the bending part of the accommodating space (for example, the first groove) along the first direction can be arc-shaped, so that the antenna module can smoothly transition from the bracket main body to the bending part, thereby reducing the difficulty of laying the antenna module in the accommodating space, thereby reducing the overall manufacturing difficulty of the middle frame assembly.

[0014] In combination with the first aspect, in certain implementations of the first aspect, the accommodating space includes a portion of two adjacent sides of the main body of the bracket.

[0015] Based on the middle frame assembly provided in the embodiment of the present application, the accommodating space can be located at a top corner of the main body of the bracket. The accommodating space is located on one side of the bent portion of the bracket and is connected to two adjacent sides of the main body of the bracket. This structure allows the antenna module to be extended in all directions, thereby enhancing the communication performance of the electronic device.

[0016] In combination with the first aspect, in certain implementations of the first aspect, a connection between two adjacent sides of the main body of the bracket is arc-shaped.

[0017] Based on the middle frame assembly in the embodiment of the present application, one side of the accommodating space located at the bent portion of the bracket can be a curved surface, and the antenna module can smoothly transition from one side of the main body to the other side, thereby reducing the difficulty of laying the antenna module in the accommodating space, thereby reducing the overall manufacturing difficulty of the middle frame assembly.

[0018] In combination with the first aspect, in some implementations of the first aspect, the accommodation space includes a through hole, and the through hole is used to accommodate a feeding part of the antenna module.

[0019] Based on the middle frame assembly of the embodiment of the present application, the accommodating space may include a through hole penetrating the bracket, so that the feeding part of the antenna module can be coupled with the feeding circuit through the through hole.

[0020] In combination with the first aspect, in some implementations of the first aspect, a bend of the accommodating space along the first direction includes a protruding portion, and the antenna module avoids the protruding portion.

[0021] Based on the middle frame assembly of the embodiment of the present application, the antenna module can avoid the raised portion located at the bend when laid in the accommodating space. The raised portion can be used to make the antenna module and the bracket more firmly combined, thereby enhancing the strength of the middle frame assembly and the electronic device.

[0022] In combination with the first aspect, in certain implementations of the first aspect, the raised portion is located at a connection between two adjacent edges of the main body of the bracket.

[0023] Based on the middle frame assembly of the embodiment of the present application, the protrusion module can be set at the top corner position of the bracket body in the accommodating space. This structure makes it difficult for the antenna module to fall off in all directions, further enhancing the strength of the middle frame assembly and the electronic device.

[0024] In combination with the first aspect, in some implementations of the first aspect, the middle frame includes a second groove, and the second groove is used to accommodate the bending portion.

[0025] Based on the middle frame assembly of the embodiment of the present application, the bracket can be connected to the middle frame by inserting the bending portion into the second groove, so that the bracket can be firmly connected to the middle frame, and at the same time can effectively reduce the overall thickness of the bracket and the middle frame, thereby reducing the thickness of the electronic device.

[0026] In combination with the first aspect, in certain implementations of the first aspect, there is a gap between the bent portion and the groove wall of the second groove.

[0027] Based on the middle frame assembly of the embodiment of the present application, the gap can be used to install the bent portion of the bracket into the second groove of the middle frame, thereby reducing the difficulty of assembling the bracket and the middle frame.

[0028] In combination with the first aspect, in certain implementations of the first aspect, a depth of the first groove located in the main body is at least 0.2 mm.

[0029] In combination with the first aspect, in certain implementations of the first aspect, a groove depth of the first groove at the bending portion is at least 0.3 mm.

[0030] In combination with the first aspect, in some implementations of the first aspect, a length of the first groove along the first direction is at least 1.2 mm.

[0031] In a second aspect, an electronic device is provided, comprising the middle frame assembly in the first aspect or each implementation of the first aspect.

[0032] In combination with the second aspect, in some implementations of the second aspect, the electronic device also includes an antenna module.

[0033] In the middle frame assembly and electronic device provided in the embodiment of the present application, the two sides of the middle frame of the middle frame assembly are respectively used to connect the display module and the back plate, so that the appearance of the electronic device can still be presented as a whole. The bracket of the middle frame assembly is provided with a receiving space for the antenna module, so that the manufacturing of the middle frame is relatively decoupled from the manufacturing of the antenna module. The middle frame assembly has a low manufacturing difficulty. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The present application relates to a middle frame of an electronic device. The electronic device may be a mobile phone, a tablet computer, a tablet computer accessory, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA) and other mobile terminals, or may also be a digital camera, a SLR camera / micro-single camera, a sports camera, a PTZ camera, a drone and other professional shooting equipment. The embodiments of the present application do not impose any special restrictions on the specific form of the electronic device. For ease of understanding, the following description takes the electronic device as an example of a mobile phone.

[0050] As an important part of electronic equipment, the middle frame assembly bears the important responsibility of carrying various components (such as antennas, etc.). The manufacturing difficulty of the middle frame assembly is related to its structure. Excessive manufacturing difficulty will not only affect the manufacturing cycle and cost, but also bring challenges to the stability of quality. The embodiment of the present application provides a middle frame assembly that can effectively reduce the manufacturing difficulty.

[0051] refer to Figure 1 , Figure 1 : is an exploded view of the middle frame assembly of the electronic device provided in the embodiment of the present application. In the embodiment of the present application, the middle frame assembly of the electronic device may include a middle frame 1 and a bracket 2. Among them, the bracket 2 can be fixed on the middle frame 1 to provide support, buffer protection or assist in assembling other components (such as circuit boards, batteries, etc.) for the middle frame 1.

[0052] In order to facilitate the description of the following embodiments, an O-xyz coordinate system is established for the middle frame assembly, wherein the thickness direction of the middle frame 1 is defined as the z-axis direction, the width direction is defined as the x-axis direction, and the length direction is defined as the y-axis direction.

[0053] In some implementations, the bracket 2 is located on one side of the middle frame 1 (hereinafter referred to as side A for ease of description).

[0054] The two sides of the middle frame 1 are respectively used to connect the display module (such as a screen) and the back plate (or can also be called a back cover). For example, the A side of the middle frame 1 is used to connect the back plate. The other side of the middle frame 1 (hereinafter referred to as the B side) is used to connect the display module. Among them, the bracket 2 can be located between the middle frame 1 and the back plate. The bracket 2 can assist the middle frame 1 in fixing other components of the electronic device, such as a battery, a motherboard, etc. In some implementations, an integrated connection method can be adopted between the middle frame 1 and the back plate, so that the appearance of the electronic device can present a visual effect of "only one shell".

[0055] The middle frame 1 may be made of metal, such as aluminum alloy, etc. The forming process of the middle frame 1 may be aluminum alloy sheet stamping. In practical applications, the metal material and forming process of the middle frame 1 may be selected based on actual conditions.

[0056] The bracket 2 can be made of various materials, such as metal, plastic or composite materials, etc. This application does not impose any special limitation on this.

[0057] The middle frame 1 and the bracket 2 can be connected in a variety of ways. For example, the middle frame 1 and the bracket 2 can be connected by fasteners (such as riveting). For another example, the middle frame 1 and the bracket 2 can be connected by bonding, welding, or tight bite. This application does not specifically limit this. The bracket 2 may not be present in the appearance of the electronic device.

[0058] It should be noted that two or more brackets may be placed on the middle frame 1. For example, Figure 1 An implementation manner in which a bracket 2 is placed at one end of the middle frame 1 is shown. In some implementation manners, a bracket (although not shown) may also be placed at the other end of the middle frame 1. The number and shape of the brackets placed on the middle frame 1 are related to the specific application scenario, and this application does not specifically limit this. The following mainly takes the bracket 2 as an example to illustrate the middle frame assembly and the electronic device proposed in this application.

[0059] In the embodiment of the present application, the bracket 2 can be used to carry the antenna module, so that the manufacturing of the antenna module is moderately decoupled from the manufacturing of the middle frame, thereby reducing the difficulty of manufacturing the middle frame assembly.

[0060] See also Figure 2 , Figure 2 2 is an exploded view of the bracket 2 and the antenna module 3 provided in the embodiment of the present application. For example, the bracket 2 includes a bending area. The bending area includes an edge of the main body 21 of the bracket and a bending portion 22 located at the edge of the main body 21. The bending portion 22 is bent along a first direction z perpendicular to the main body 21 and is connected to the middle frame 1 ( Figure 2 The bending area includes a receiving space 23 , and the receiving space 23 is used to receive the antenna module 3 .

[0061] The antenna module 3 is a device for receiving / sending electromagnetic wave radiation. In some cases, the antenna module 3 may also be referred to as a radiator. The radiator may convert the waveguide energy from the transmitter into radio waves, or convert the radio waves into waveguide energy, for radiating and receiving radio waves.

[0062] It should be noted that the shape and size of the antenna module 3 have a crucial impact on the performance of the electronic device. Usually, during the development process of electronic equipment, the antenna module needs to be debugged many times. In the traditional MDA middle frame structure, part of the middle frame shell material is designed as an antenna, which makes it difficult to debug the antenna. In addition, the traditional MDA middle frame must adopt a post-processing process (such as CNC processing), which prolongs the overall development cycle of the electronic device and the cost of the middle frame shell material is relatively high. The solution of accommodating the antenna module on the bracket provided in the embodiment of the present application decouples the design of the antenna module 3 from the main middle frame design of the middle frame assembly, reduces the difficulty of debugging the antenna module, and thus shortens the overall development cycle of the electronic device and reduces development and manufacturing costs.

[0063] The accommodating space 23 can be in various shapes. Figure 2 As shown, the accommodation space 23 can be a first groove located in the bending area, and the bottom surface of the first groove is located on the first surface of the main body 21, and the first surface of the main body 21 is the surface away from the middle frame 1 (i.e., the surface facing the opposite direction of the z-axis). The antenna module 3 can be arranged in the first groove, so that the antenna module 3 does not need to occupy extra space to be fixed on the bracket 2.

[0064] In some implementations, the bottom surface of the first groove is also located at the first surface of the bending portion 22, and the first surface of the bending portion 22 is connected to the first surface of the main body 21. In other words, the first groove can be provided at the bending point between the main body 21 and the bending portion 22. Figure 2 As shown, the first groove (ie, the accommodating space 23) may be a groove with a bend, and the antenna module 3 also presents a bend shape correspondingly.

[0065] In other implementations, although not shown, the bottom surface of the first groove is located on the second surface of the main body 21, and the second surface of the main body 21 is the surface close to the middle frame 1 (i.e., the surface facing the z-axis direction). Optionally, the bottom surface of the first groove is also located on the second surface of the bending portion 22, and the second surface of the bending portion 22 is adjacent to the second surface of the main body 21. In other words, the accommodating space 23 can also be located on the inner surface of the bending area (the surface with a bending angle less than 180 degrees), and this application does not specifically limit this.

[0066] It should be noted that Figure 2Only one implementation of the accommodating space 23 is shown. In other implementations, the accommodating space may not be groove-shaped. For example, the antenna module 3 may be laid on the surface of the bending area. Alternatively, the accommodating space 23 is groove-shaped in the portion of the main body 21, and the accommodating space 23 is not groove-shaped in the portion of the bending portion 22. The antenna module 3 is arranged in the groove in the main body 21 and laid on the surface of the bending portion 22. Alternatively, the accommodating space 23 is not groove-shaped in the portion of the main body 21, and the accommodating space is groove-shaped in the portion of the bending portion 22. The antenna module 3 is laid on the surface of the main body 21 and connected to the groove in the bending portion 22. This application does not specifically limit this.

[0067] Optionally, the bend in the accommodating space 23 along the first direction z is arc-shaped. In other words, the connection between the main body 21 and the bend 22 is arc-shaped. In other words, the bend in the first direction z of the bottom of the first groove is arc-shaped. In this case, when laying the antenna module 3, the main body 21 and the bend 22 can be smoothly transitioned, thereby reducing the difficulty of laying the antenna module 3 in the accommodating space 23, and reducing the overall manufacturing difficulty of the middle frame assembly and the electronic device.

[0068] Optionally, the accommodating space 23 includes a portion of two adjacent sides of the bracket main body 21. In other words, the accommodating space 23 can be located at a vertex of the bracket main body 21. For ease of description, the side of the bending portion 22 connected to one side of the main body 21 is called the A side, and the side connected to the other side of the main body 21 is called the B side. The bottom surface of the accommodating space 23 located at the bending portion 22 can be included in the A side and the B side. This structure allows the antenna module 3 to extend in all directions, thereby enhancing the communication performance of the electronic device.

[0069] It should be noted that, in some implementations, although not shown, the accommodating space 23 may also include two or more vertex corners (such as two adjacent vertex corners) located at the bracket body 21. This is related to the application scenario requirements of the antenna module 3 and the bracket 2, and this application does not specifically limit this.

[0070] Optionally, the connection between two adjacent sides of the main body 21 of the bracket is arc-shaped. That is, the connection between surface A and surface B is arc-shaped. The antenna module 3 can smoothly transition from surface A to surface B at the bend. This structure can reduce the difficulty of laying the antenna module in the accommodation space, thereby reducing the overall manufacturing difficulty of the middle frame assembly and the electronic device.

[0071] Optionally, the bend in the accommodating space 23 along the first direction includes a convex portion 231. Figure 2The raised portion 231 can be regarded as a raised portion located at the bend in the accommodation space 23 (first groove). The raised portion 231 can be a raised portion formed by avoiding the area when the groove is dug on the bracket 2. Alternatively, the raised portion can also be a raised portion installed after the groove is dug on the bracket 2. This application does not specifically limit this.

[0072] The portion of the protruding portion 231 located on the bracket body 21 may be flush with the surface of the body 21 that is not grooved. The portion of the protruding portion 231 located on the bracket bending portion 22 may be flush with the surface of the bending portion 22 that is not grooved.

[0073] It should be noted that the present application does not impose any particular limitation on the length, width and shape of the protruding portion 231 on the bracket body portion 21 and the bending portion 22 .

[0074] Correspondingly, the antenna module 3 may include a through hole 31, which may be formed when the antenna module 3 is laid in the accommodation space 23 to avoid the raised portion 231. In other words, the through hole 31 of the antenna module may be snapped onto the raised portion 231 of the accommodation space 23, so that the antenna module 3 is not easily dropped from the bracket 2, thereby enhancing the stability of the antenna module 3 laid in the accommodation space 23, and further enhancing the strength of the middle frame assembly and the electronic device.

[0075] The raised portion 231 may be located at various positions of the bending portion of the accommodation space 23 along the first direction. Figure 2 As shown, the raised portion 231 can be located at the connection of two adjacent sides of the bracket main body 21. In other words, the raised portion 231 can be located at a vertex of the bracket main body 21. The raised portion 231 is bent from one side of the bracket main body 21 to the other side, forming a bent shape. This structure makes it difficult for the antenna module 3 to fall off in all directions, further enhancing the strength of the middle frame assembly and the electronic device.

[0076] It should be noted that, in some other implementations, although not shown, the raised portion 231 may also be located on one side of the bracket body 21, for example, in a straight strip shape. It should also be noted that, although not shown, the accommodation space 23 may include two or more raised portions, for example, the accommodation space 23 may be provided with raised portions on two adjacent sides of the bracket body 23. This application does not specifically limit this.

[0077] In some implementations, the antenna module 3 may also avoid other components on the bracket 2. For example, the antenna module 3 may avoid the fixing parts used to connect the bracket 2 and the middle frame 1, or avoid other components on the bracket 2. In other words, the shape of the antenna module 3 is also related to the application scenario of the bracket 2, and this application does not specifically limit this.

[0078] The antenna module 3 may be placed in various ways in the accommodation space 23. For example, the antenna module 3 may be a sheet radiator, for example, it may include a conductive layer or a conductive sheet, such as silver paste, copper sheet, etc. This application does not specifically limit this.

[0079] It should be noted that the present application does not specifically limit the number of accommodating spaces on the bracket 2. In other words, the present application does not specifically limit the number of antenna modules.

[0080] See also Figure 3 , Figure 3 A schematic diagram of a bracket 2 provided for an embodiment of the present application. The bracket 3 includes a accommodating space 23A and also includes a accommodating space 23B. The introduction of the accommodating space 23A and the accommodating space 23B can refer to the description of the accommodating space 23 above. Schematically, the accommodating space 23A and the accommodating space 23B can be respectively located at two vertex corners of the main body 21 of the bracket. The accommodating space 23A and the accommodating space 23B may not be connected to each other, or they may be connected to form one accommodating space (although not shown), which is related to the design of the bracket 2 and the antenna module 3. The shapes of the accommodating space 23A and the accommodating space 23B may be the same or different, which is related to the design of the bracket 2 and the antenna module 3, and the present application does not specifically limit this.

[0081] It should be noted that, in some implementations, the distance between the accommodating space 23A and the accommodating space 23B may be determined based on application requirements of the antenna module, and this application does not specifically limit this.

[0082] See also Figure 4 , Figure 4 Provided in the embodiments of this application Figure 3 The antenna module 3A and the antenna module 3B can be laid in the accommodation space 23A and the accommodation space 23B respectively.

[0083] See also Figure 5 , Figure 5 Schematic diagram of the antenna module 3 provided in the embodiment of the present application being laid in the accommodation space 23. The antenna module 3 is marked in gray. Figure 5 The side of the bracket 2 away from the middle frame 1 is shown.

[0084] Optionally, the accommodating space 23 further includes a through hole 232, and the through hole 232 is used to accommodate the feeding part 31 of the antenna module 3. Figure 5 As shown, the antenna module 3 can extend along the through hole 232 to the other side (the side of the bracket 2 close to the middle frame 1 ).

[0085] The feeding part 31 can be coupled to a feeding circuit. The feeding circuit is a combination of all resistors used for receiving and transmitting radio frequency signals. For example, a single feeding path can include a transceiver and a radio frequency front-end circuit. The coupling connection can be a direct electrical connection or an indirect electrical connection, which is not particularly limited in the application.

[0086] It should be noted that in some implementations, according to the design of the antenna module function, the antenna module may also include a grounding portion, and the bracket 2 may be designed as a structure for grounding the antenna module based on grounding requirements, and this application does not specifically limit this.

[0087] See also Figure 6 , Figure 6 Another schematic diagram of the antenna module 3 provided in the embodiment of the present application being laid in the accommodation space 23. The antenna module 3 is marked in gray. Figure 6 The side of the bracket 2 close to the middle frame 1 is shown. A feeding circuit can be placed on the middle frame 1, and the feeding part 31 on the antenna module 3 can be coupled to the feeding circuit.

[0088] In some implementations, the area adjacent to the through hole 232 of the bracket 2 for placing the feeding portion 31 includes a thinned area. Figure 6 As shown, the feeding part 31 can extend to cover a part of the adjacent thinned area after passing through the through hole 232. The thinned area allows the feeding part 31 to have a space for accommodation. After laying the antenna module 3, the side of the bracket 2 close to the middle frame 1 can be relatively flat, reducing the impact of other components installed on the middle frame 1 and saving the space occupied by the middle frame components.

[0089] See also Figure 7 , Figure 7 The bracket provided in the embodiment of the present application is Figure 3 As described above, the accommodation space 23 may be a first groove located in the bending area, and the antenna module 3 is laid in the accommodation space 23 .

[0090] It should be noted that the bracket 2 is bent along the first direction. In some implementations, the inner angle a of the bend may be slightly greater than 90 degrees (eg Figure 7 Or it may be slightly less than or equal to 90 degrees, which is not particularly limited in this application.

[0091] See also Figure 8 , Figure 8 A schematic diagram of the dimensions of the accommodation space 23 provided in an embodiment of the present application.

[0092] Optionally, the groove depth d1 of the first groove (accommodating space 23 ) located in the main body 21 of the bracket may be at least 0.2 mm, leaving sufficient space for laying the antenna module 3 .

[0093] Optionally, the groove depth d2 of the first groove (accommodating space 23 ) located at the bent portion 22 of the bracket may be at least 0.3 mm, leaving sufficient space for laying the antenna module 3 .

[0094] Optionally, the length d3 of the first groove (accommodating space 23 ) located at the bent portion 22 of the bracket along the first direction may be at least 1.2 mm, so that the antenna module 3 has sufficient space to extend in the first direction.

[0095] Optionally, the length d4 of the bent portion 22 of the bracket excluding the accommodating space 23 along the first direction may be approximately 0.3 mm.

[0096] It should be noted that Figure 8 The embodiment shows that the bottom of the first groove is a plane (such as a plane located at the upper edge yox of the bracket body 21, and a plane located at the upper edge zox of the bracket bending portion 22). In some other embodiments, although not shown, the bottom of the first groove may also be an inclined surface, and the groove depth gradually increases or decreases along the inclined surface. This application does not specifically limit this.

[0097] In some implementations, the middle frame 1 includes a second groove 11, and the second groove 11 is used to accommodate the bent portion 22 of the bracket.

[0098] See also Fig. 9 , Fig. 9 Schematic diagram of the connection between the bracket 2 and the middle frame 1 provided in the embodiment of the present application. The depth of the second groove 11 is related to the length of the bracket bending portion 22 along the first direction, and the present application does not specifically limit this. The provision of the second groove 11 can effectively reduce the overall thickness of the bracket 2 and the middle frame 1, thereby reducing the thickness of the electronic device.

[0099] In some implementations, the width of the portion of the bracket bending portion 22 where the antenna module 3 is placed may be longer than the width of the portion of the bending portion 22 where the antenna module 3 is not placed. For example, Figure 3 , Figure 4 and Figure 5 The design of the second groove 22 can be based on the portion of the bracket bending portion 22 where the antenna module 3 is placed. For example, the second groove 22 can be used to accommodate the portion of the bracket bending portion 22 where the antenna module 3 is placed, which extends in the first direction compared to the portion where the antenna module 3 is not placed. Thus, the groove area on the middle frame 1 can be reduced, and the strength and stability of the middle frame assembly can be enhanced.

[0100] In some implementations, there is a gap between the bent portion 22 of the bracket and the groove wall of the second groove 11. The gap can be used to install the bent portion 22 of the bracket into the second groove 11 of the middle frame 1, reducing the difficulty of assembling the bracket 2 and the middle frame 1.

[0101] In some implementations, the middle frame 1 may include a plurality of brackets 2 as described above. For example, the upper and lower portions of the middle frame 1 are connected to brackets 2A and 2B, respectively, and each bracket may be provided with a receiving space for receiving an antenna module. This application does not specifically limit this.

[0102] In the embodiment of the present application, the electronic device may further include a display module (such as a screen), a back plate, and other components such as a battery. For example, the screen and the back plate are respectively arranged on both sides of the middle frame. A bracket is arranged between the middle frame and the back plate, and the bracket can assist in fixing other components (such as a motherboard and a battery space). The screen, the middle frame assembly, and the bottom plate can be connected to form a closed structure.

[0103] In actual applications, the materials of the screen and base plate of the electronic device can be selected according to needs. For example, the screen can be an organic light-emitting diode display or a liquid crystal display, etc., and can be a rigid screen or a flexible screen; the back panel material can be metal, plastic, ceramic, etc., and this application does not limit this.

[0104] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
