Description

Technical Field

[0001] This application relates to the field of electronic devices, and more particularly to an electronic device. Background Technology

[0002] Currently, as users demand increasingly sophisticated appearances from electronic products, many electronic devices utilize high-end, textured metal components. However, the prevalence of metal in the casing of electronic devices can easily shield antenna signals, affecting both transmission and reception. Therefore, balancing antenna clearance requirements in scenarios where metal is extensively used in electronic device casings is a problem that needs to be addressed. Utility Model Content

[0003] This application provides an electronic device. The electronic device includes a housing and a screen. The housing includes a frame and a back cover. The frame connects the screen and the back cover. The frame includes a first portion and a second portion. Both the first portion and the back cover are made of a metallic material. The first portion has at least one antenna slot. At least a portion of the second portion is disposed between the first portion and the back cover. The second portion is made of a non-metallic material, and at least a portion of the second portion fills the antenna slot and surrounds at least a portion of the back cover. The second portion and the screen are stacked along the thickness direction of the electronic device.

[0004] Understandably, at least a portion of the second part can fill the antenna gap. The second part is made of non-metallic material, which, while avoiding interference with the antenna signal, can also seal the antenna gap, preventing external moisture and dust from interfering with the operation of the internal components of the electronic device. Both the first part and the back cover are made of metallic material. When the frame and back cover of the electronic device are largely made of metal, the device's casing is stronger, and the frame can fit seamlessly with the back cover to achieve a premium all-metal look and improved appearance. By creating a gap between the first part and the back cover, and filling this gap with the second part made of non-metallic material, at least a portion of the second part can be positioned between the first part and the back cover, creating a clear area between them. This reduces the shielding effect of the metal back cover on the antenna signal, resulting in better antenna signal performance for electronic devices with metal back covers.

[0005] In one possible implementation, the second part surrounds the back cover.

[0006] It is understood that the second part surrounds at least part of the back cover. This can be understood as the second part surrounding a portion of the back cover or completely encircling it. The degree to which the second part surrounds the back cover can be illustrated by the size of the central angle between the two opposite ends of the second part in the circumferential direction around the central axis of the back cover. The central axis of the back cover is perpendicular to the plane containing the back cover. It should be noted that the perpendicularity described here is not absolute in a mathematical sense; it can be approximately perpendicular, allowing for slight deviations. The angle between the central axis of the back cover and the plane containing the back cover can be in the range of 80° to 100°. The larger the central angle corresponding to the second part surrounding the back cover, the larger the resulting clearance area, allowing the antenna to transmit and receive signals better. In this embodiment, the second part surrounds the entire back cover, resulting in a large clearance area, and the color and shape differences on the peripheral sides of the frame are small, resulting in good consistency in the appearance of the casing.

[0007] In one possible implementation, the step difference between the end face of the second part away from the screen and the surface of the back cover away from the screen is in the range of -0.1mm to +0.1mm.

[0008] Understandably, the step difference between the end face of the second part away from the screen and the surface of the back cover away from the screen is in the range of -0.1mm to +0.1mm. The second part is connected between the first part and the back cover. There is no step difference or a small step difference between the end face of the second part away from the screen and the second surface of the back cover at the connection position. The appearance of the shell is relatively flat near the gap position, without protrusions or large step differences. The appearance of the shell is good, and the user does not have obvious steps / scratches when touching it, resulting in a better user experience.

[0009] In one possible implementation, the first part is frame-shaped, the second part includes a main body and a boss, the main body and the first part are fixedly connected, the boss and the inner side of the main body are fixedly connected, the boss and the main body form a mounting groove, and the periphery of the rear cover is fixedly connected to the mounting groove.

[0010] Understandably, by providing a mounting groove in the second part, the periphery of the back cover is fixedly connected to the mounting groove, allowing the second part to better surround the back cover. Furthermore, during the assembly process of the back cover and the frame, the mounting groove can also serve as a positioning structure for the installation and positioning of the back cover, which helps improve assembly efficiency.

[0011] In one possible implementation, the electronic device also includes an adhesive backing. The adhesive backing is disposed between the boss and the back cover, and the boss and the back cover are fixedly connected by the adhesive backing.

[0012] Understandably, the boss and back cover can be secured together using adhesive. The adhesive can also be used to seal and waterproof the gap between the back cover and the frame.

[0013] In one possible implementation, the second part is a plastic component. The second part and the first part are integrally molded structural components. Here, an integrally molded structural component means that the two components are obtained through an integral molding process, whereby the component is connected to the other component during the formation of one of the components, without requiring further processing (such as bonding, welding, snap-fit ​​connections, or screw connections) to join the two components together.

[0014] It is understandable that the second part can be formed onto the first part through injection molding, and can be fixedly connected to the first part during the molding process of the second part. During the preparation of the frame, no additional process is required to assemble the second part and the first part.

[0015] In one possible implementation, the electronic device further includes a latch. The latch is fixedly connected to the inner surface of the back cover. The second part has a limiting groove, in which the latch engages.

[0016] Understandably, by using a latch and a limiting groove, the latch and back cover are fixedly connected, and the latch engages within the limiting groove, thus limiting the relative positioning of the back cover and the middle frame. For example, this can reduce the relative movement of the back cover relative to the middle frame in the XY plane. Since the back cover is made of metal and the second part of the middle frame is made of rubber, the metal back cover is harder than the rubber second part. When the electronic device is subjected to mechanical environments such as drops, the latch and limiting groove can reduce the impact of the back cover on the second part, minimizing damage and allowing the second part to better fill gaps.

[0017] In one possible implementation, the second part has a third surface. The third surface faces the interior of the electronic device. A limiting groove is located on the third surface.

[0018] In this way, at least a portion of the second part can limit the hook in the thickness direction of the electronic device.

[0019] In one possible implementation, the hook and the back cover are integrally molded structural components.

[0020] Understandably, compared to the welding assembly method used for the hooks and back cover, this embodiment uses a one-piece molding process to form the hooks and back cover. This reduces the likelihood of visible marks on the back cover, resulting in a more refined appearance for the casing. Furthermore, the back cover and hooks do not require additional assembly steps, and their connection strength is superior.

[0021] In one possible implementation, the first part includes a first segment and a second segment arranged circumferentially along the frame. The first segment is used to provide button mounting holes, card slots, or sound outlets. An antenna slot is provided on the second segment. The first segment and the back cover are integrally formed structural components. There is a gap between the second segment and the back cover, and at least part of the second part fills the gap.

[0022] Understandably, the connection strength between the first part and the back cover is relatively good. For example, in the manufacturing process of the electronic device housing, the first part of the frame and the back cover can be integrally formed by metal processing technology, and then the second part can be formed on the first part by processes such as insert injection molding, so as to obtain a housing that includes both metal and non-metal materials.

[0023] In one possible implementation, a glue-pulling structure is provided at the joint between the first part and the second part near the antenna slot.

[0024] Understandably, the adhesive-bonded structure, also known as a mechanically interlocked structure or a bonded composite structure, is a method of firmly connecting plastic and metal through physical structure in the injection molding process. This structure can improve the bonding strength and avoid the problems of low bonding strength and slow bonding speed that occur in traditional adhesive bonding methods. Grooves or protrusions can be provided on the surface of the first part that contacts the second part, making the contact surface of the first and second parts rough and uneven. During the molding process of the first and second parts, the contact area between them is large, and the friction on the connecting surface is large, thus resulting in better bonding strength between the first and second parts.

[0025] In one possible implementation, the electronic device further includes an antenna. The radiator of the antenna is formed by at least a portion of the first part, or the radiator of the antenna is fixed to the first part. There are various ways in which the radiator of the antenna can be formed, and this application does not impose any limitation. Attached Figure Description

[0038] The embodiments of this application are described below with reference to the accompanying drawings.

[0039] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Rotary connection" refers to a connection where the components can rotate relative to each other after connection. "Sliding connection" refers to a connection where the components can slide relative to each other after connection. The directional terms mentioned in the embodiments of this application, such as "up," "down," "left," "right," "inner," and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. "Multiple" means at least two.

[0040] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0041] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0042] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0043] Furthermore, the limitations on relative positional relationships mentioned in the embodiments of this application, such as parallel, perpendicular, and aligned, are all relative to the current technological level and are not absolutely strict limitations. Slight deviations are allowed; approximations of parallelism, perpendicularity, and alignment are all acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 degrees (°) and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 degrees and 100 degrees.

[0044] Connection / linking: can refer to a mechanical or physical connection, that is, A and B are connected or linked. It can mean that there are fastened components (such as screws, bolts, rivets, etc.) between A and B, or that A and B are in contact with each other and are difficult to separate.

[0045] Coupling can be understood as direct coupling and / or indirect coupling. "Coupled connection" can be understood as a direct coupling connection and / or indirect coupling connection. Direct coupling can also be called "electrical connection," which can be understood as physical contact and electrical conduction between components; it can also be understood as the form of connection between different components in a circuit structure through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB). "Indirect coupling" can be understood as electrical conduction between two conductors through a gap / non-contact method. In one embodiment, indirect coupling can also be called capacitive coupling, for example, signal transmission is achieved by forming an equivalent capacitance through coupling between the gaps between two conductive parts.

[0046] Relative / Relative Setting: A relative setting with B can refer to A and B being face-to-face. For example, when two structures are set relative to each other, at least a portion of the two structures overlap along a certain direction.

[0047] A radiator, or antenna stub, is a device in an antenna used to receive / transmit electromagnetic wave radiation. In some cases, the term "antenna" is narrowly defined as a radiator, which converts guided wave energy from the transmitter into radio waves, or converts radio waves into guided wave energy, for radiating and receiving radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted to the transmitting radiator via a feed line, where it is converted into electromagnetic wave energy of a specific polarization and radiated in the desired direction. The receiving radiator converts electromagnetic wave energy of a specific polarization from a specific direction in space back into modulated high-frequency current energy, which is then transmitted to the receiver input via a feed line.

[0048] The radiator (or antenna stub) may include a conductor with a specific shape and size, such as a wire or a sheet, and this application does not limit the specific shape. In one embodiment, the wire radiator may be simply referred to as a wire antenna. In one embodiment, the wire radiator may be implemented by a conductive frame, and may also be referred to as a frame antenna. In one embodiment, the wire radiator may be implemented by a support conductor, and may also be referred to as a support antenna.

[0049] It is understood that the specific embodiments described herein are merely for explaining the relevant application and not for limiting the application. It should also be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings.

[0050] Figure 1 This is a schematic diagram of the structure of the electronic device 1000 provided in some embodiments of this application. Figure 2 yes Figure 1 The diagram shows the structure of the electronic device 1000 from another angle. Figure 3 yes Figure 1 The diagram shows a partially exploded view of the electronic device 1000 in some embodiments.

[0051] like Figures 1 to 3 As shown, the electronic device 1000 provided in this application can be a mobile phone, watch, tablet computer, laptop computer, personal digital assistant (PDA), smart home device, personal computer, laptop computer, or other electronic device 1000 with wireless communication capabilities. The electronic device 1000 can also be a handheld device with wireless communication capabilities, a computing device, or other processing device connected to a wireless modem, or other devices capable of receiving and radiating electromagnetic wave signals. Figure 1 The electronic device 1000 of the embodiment shown will be described using a mobile phone as an example.

[0052] For ease of description, the thickness direction of electronic device 1000 is defined as the Z-axis, the length direction as the Y-axis, and the width direction as the X-axis. It is understood that the coordinate system of electronic device 1000 can be set according to actual needs, and this application does not impose any limitations on it.

[0053] In some embodiments, the electronic device 1000 may include a housing 100 and a screen 200. It is understood that... Figure 1 and Figure 2 The electronic device 1000 is shown only schematically, and the actual shape, size, and construction of these components are not subject to change. Figure 1 and Figure 2 Limited. The screen 200 can be mounted on the housing 100. (Attached) Figure 1 The diagram illustrates a roughly rectangular structure formed by the screen 200 and the housing 100. The screen 200 can be used to display images, text, etc. It should be understood that, in the embodiments of this application, when a user holds (typically vertically and facing the screen 200) the electronic device 1000, the electronic device 1000 is positioned with a top, bottom, left side, and right side. The top of the electronic device 1000 may face the sky. In this embodiment, the arrangement direction of the top and bottom may be parallel to the Y-axis. The arrangement direction of the left and right sides may be parallel to the X-axis. It should be noted that the parallelism described here is not absolute in a mathematical sense; it can be approximately parallel, allowing for slight deviations, and the angle can be within the range of 0° to 10°.

[0054] For example, the housing 100 can be used to support the screen 200 and related components of the electronic device 1000. The housing 100 may include a mid-frame 10 and a rear cover 20. The rear cover 20 and the screen 200 can be respectively mounted on opposite sides of the mid-frame 10. The arrangement direction of the rear cover 20 and the screen 200 can be parallel to the Z-axis direction. The rear cover 20 can be fixedly connected to the mid-frame 10 by means of adhesive bonding, welding, etc. In this case, the screen 200, the mid-frame 10, and the rear cover 20 can together enclose the internal space of the electronic device 1000. The internal space of the electronic device 1000 can be used to house the internal components of the electronic device 1000, such as a battery, speaker, microphone, or earpiece.

[0055] In some embodiments, the back cover 20 may be made of a conductive material such as metal. For example, materials such as aluminum, titanium, and stainless steel. It is understood that compared to a back cover 20 made of materials such as glass or ceramic, a metal back cover 20 has a better feel and can provide a better user experience.

[0056] In some embodiments, the middle frame 10 may include a border 1 and a middle plate 2. The border 1 may surround and connect to the middle plate 2. In some embodiments, the middle frame 10 may also include only the border 1. The border 1 connects between the back cover 20 and the screen 200, and together with the screen 200 and the back cover 20, can enclose the internal space of the electronic device 1000. The middle plate 2 may be located within the internal space of the electronic device 1000.

[0057] like Figure 3As shown, the border 1 may include a first short side 101 and a second short side 102 arranged opposite to each other, and a first long side 103 and a second long side 104 arranged opposite to each other. Both the first short side 101 and the second short side 102 can be connected between the first long side 103 and the second long side 104. An angle (e.g., a 90° angle) may be formed between the first long side 103 and the first short side 101. The length of the first long side 103 may be greater than the length of the first short side 101. It should be understood that the length of the first long side 103 may refer to its dimension in its extension direction. The length of the first short side 101 may refer to its dimension in its extension direction. In some embodiments, the first long side 103, the second long side 104, the first short side 101, and the second short side 102 may all be elongated. The border 1 may also include multiple corners. Any two adjacent pairs of the first long side 103, the second long side 104, the first short side 101, and the second short side 102 can be connected by a corner. In some other embodiments, any corner of the frame 1 can also be considered as part of the long or short side adjacent to that corner.

[0058] In this embodiment, when the user holds the electronic device 1000 (see [link]), Figure 1 and Figure 3 When the first short side 101 is located at the top of the electronic device 1000, the second short side 102 is located at the bottom of the electronic device 1000, the first long side 103 is located at the left side of the electronic device 1000, and the second long side 104 is located at the right side of the electronic device 1000.

[0059] It should be noted that, Figure 3 The border 1 shown is illustrated using a non-foldable electronic device 1000 as an example. When the electronic device 1000 is a foldable electronic device 1000 (e.g., a two-fold or three-fold device), the first long side 103, the second long side 104, the first short side 101, and the second short side 102 can be understood as the long and short sides on the middle frame 10 corresponding to one of the folds in the multiple folds.

[0060] Exemplary, the electronic device 1000 may also include a circuit board (not shown). The circuit board may be a printed circuit board (PCB). The circuit board may be located between the mid-frame 10 and the rear cover 20. Electronic components, such as radio frequency chips, may be mounted on the circuit board. In some embodiments, the circuit board may also be located between the screen 200 and the mid-frame 10. This application does not limit the specific location of the circuit board.

[0061] In some embodiments, the electronic device 1000 may also include an antenna (not shown). Exemplarily, the antenna may consist of a conductive portion of the frame 1 of the electronic device 1000 as the main radiator and / or a parasitic branch. The antenna may be used to receive or transmit signals in communication bands used for satellite messaging and / or satellite telephones.

[0062] Understandably, when the frame 10, border 1, and back cover 20 of the electronic device 1000 are largely made of metal, the casing 100 of the electronic device 1000 becomes stronger, and the border 1 can work in conjunction with the back cover 20 to achieve a premium all-metal look and improved appearance. However, large areas of metal can easily shield antenna signals, affecting the signal transmission and reception of the electronic device 1000's antenna. The following section, with reference to the accompanying drawings, will introduce several implementation methods to balance antenna clearance requirements and achieve better antenna signal transmission and reception when the electronic device 1000 uses large areas of metal in the border 1 and back cover 20.

[0063] Figure 4 yes Figure 1 A partial cross-sectional view of one embodiment of the electronic device 1000 shown at another angle at AA. Figure 5 yes Figure 2 A partial cross-sectional view of one embodiment of the electronic device 1000 shown at another angle at BB.

[0064] like Figure 4 and Figure 5 As shown, the frame 1 of the electronic device 1000 may include a first part 11 and a second part 12. The first part 11 is fixedly connected to the second part 12. The first part 11 may be made of a metallic material, such as aluminum, titanium, or stainless steel. The second part 12 may be made of a non-metallic material, such as plastic, rubber, etc. The first part 11 surrounds the second part 12, and the first part 11 may be used to form the main appearance surface of the frame 1.

[0065] For example, when the screen 200 is mounted on the frame 1, the screen 200 and the second part 12 are stacked in the thickness direction of the electronic device 1000. The first part 11 surrounds the screen 200. The first part 11, which is made of metal, is stronger than the second part 12, which is made of non-metallic material, and can better protect the screen 200.

[0066] In some embodiments, the antenna may include at least one radiator. A first portion 11 may be used as the radiator of the antenna. Exemplarily, the first portion 11 may have multiple antenna slots 1101. Metal segments may be included between the multiple antenna slots 1101, and at least one metal segment may be the radiator of the antenna. At least a portion of the second portion 12 may fill the antenna slots 1101. The second portion 12 is made of an insulating non-metallic material, and while avoiding interference with the antenna signal, the second portion 12 can be used to seal the antenna slots 1101, preventing external moisture and dust from interfering with the operation of the internal components of the electronic device 1000.

[0067] It is understandable that the antenna slot 1101 can be set at any position on the frame 1, for example, Figure 1 and Figure 2 The diagram illustrates that antenna slots 1101 are present on the first short side 101, the second short side 102, the first long side 103, and the second long side 104 of the frame 1. Antenna radiators can be installed on all four sides of the frame 1. The more antennas present, the better the communication signal of the electronic device 1000. The number and position of antenna slots 1101 on each side of the frame 1 are not limited to those shown in the accompanying drawings. At least one antenna slot 1101 is provided on the first part 11. The number and position of antenna slots 1101 are not limited in this application, and those skilled in the art can design them according to requirements.

[0068] In other embodiments, the radiator of the antenna may also be a separate structural component disposed within the internal space of the electronic device 1000, for example, fixedly connected to the first portion 11 of the frame 1. For example, the radiator of the antenna may be disposed on a circuit board inside the electronic device 1000.

[0069] In some embodiments, at least a portion of the second part 12 may be disposed between the first part 11 and the rear cover 20. A gap 30 may be present between the first part 11 and the rear cover 20, the gap 30 connecting the internal space of the electronic device 1000 to the outside world and surrounding at least a portion of the rear cover 20. At least a portion of the second part 12 may fill the gap 30 and surround at least a portion of the rear cover 20. Exemplarily, the gap 30 is enclosed by the peripheral side surfaces 203 of the first part 11 and the rear cover 20. The gap 30 serves to form a clearance area for the antenna. It is understood that both the first part 11 and the rear cover 20 are made of metallic material. By providing a gap 30 between the first part 11 and the rear cover 20 and filling the gap 30 with the second part 12 made of a non-metallic material, a clearance area of ​​a certain area can be formed between the rear cover 20 and the first part 11, reducing the shielding effect of the metallic rear cover 20 on the antenna signal and resulting in better antenna signal strength for the electronic device 1000 with the metallic rear cover 20. In addition, the second part 12 fills the gap 30 and can also be used to seal the gap 30 to prevent external moisture and dust from entering the interior of the electronic device 1000 through the gap 30 and interfering with the operation of the internal components of the electronic device 1000.

[0070] It is understood that the second part 12 surrounds at least a portion of the rear cover 20. This can be understood as the second part 12 either partially surrounds the rear cover 20 or completely surrounds it. The extent to which the second part 12 surrounds the rear cover 20 can be illustrated by the size of the central angle between the opposite ends of the second part 12 in the circumferential direction around the central axis of the rear cover 20. The central axis of the rear cover 20 is perpendicular to the plane containing the rear cover 20. It should be noted that the perpendicularity described here is not absolute in a mathematical sense; it can be approximately perpendicular, allowing for slight deviations. The angle between the central axis of the rear cover 20 and the plane containing the rear cover 20 can be in the range of 80° to 100°. The larger the central angle corresponding to the second part 12 surrounding the rear cover 20, the larger the resulting clearance area, allowing the antenna to transmit and receive signals better. For example, Figure 2 The diagram illustrates that the second part 12 encircles the entire back cover 20, and the second part 12 is fitted around the periphery of the back cover 20. It can be understood that, compared to the second part 12 encircling the back cover 20, Figure 2 The diagram shows that the second part 12 surrounds the entire back cover 20, forming a large clearance area, and the color and shape differences of the perimeter 203 of the frame 1 are small, resulting in good appearance consistency of the shell 100.

[0071] In some embodiments, the gap 30 between the first part 11 and the rear cover 20 can be composed of a plurality of discontinuous sub-gap sections. The second part 12 can include a plurality of sub-sections (not shown). In the circumferential direction around the central axis of the rear cover 20, the plurality of sub-sections of the second part 12 are spaced apart, filling the plurality of sub-gap sections. That is, along the circumference of the frame 1, the plurality of sub-sections of the second part 12 can be spaced apart, thereby forming a plurality of clearance areas at different positions along the circumference of the frame 1. Those skilled in the art can adjust the shape of the second part 12 and the number of sub-sections according to the requirements of the antenna signal, thereby adjusting the shape and number of clearance areas. Furthermore, along the circumference of the frame 1, the cross-sectional shape of the second part 12 at different positions can be different, as can be referred to... Figure 5 The two magnification parts in the middle. From Figure 5 It can be clearly seen that the cross-sectional shape of the second part 12 can be adaptively adjusted according to the shape of the gap 30.

[0072] In some embodiments, the first portion 11 may be frame-shaped. The second portion 12 may include a main body 121 and a boss 122. Figure 4 The main body 121 and the boss 122 are schematically distinguished by dashed lines. The main body 121 can be fixedly connected to the first part 11. The boss 122 can be fixedly connected to the inner side of the main body 121. The inner side of the main body 121 refers to the side of the main body 121 away from the first part 11. The boss 122 and the main body 121 can form a mounting groove 123. The periphery of the rear cover 20 is fixedly connected to the mounting groove 123. It can be understood that by providing the mounting groove 123 on the second part 12 and fixing the periphery of the rear cover 20 to the mounting groove 123, the second part 12 can better surround the rear cover 20. Furthermore, during the assembly process of the rear cover 20 and the frame 1, the mounting groove 123 can also serve as a positioning structure for the installation and positioning of the rear cover 20, which helps to improve assembly efficiency.

[0073] In some embodiments, the frame 1 and the back cover 20 can be fixedly connected by means of adhesive bonding, welding, or other methods. For example, the electronic device 1000 also includes an adhesive backing 300. The adhesive backing 300 can be fixedly connected between the frame 1 and the back cover 20. The back cover 20 is fixedly connected to the frame 1 via the adhesive backing 300.

[0074] In some embodiments, at least a portion of the main body 121 of the second part 12 may fill the gap 30. An adhesive backing 300 may be provided between the boss 122 and the back cover 20, and the boss 122 and the back cover 20 may be fixedly connected by the adhesive backing 300. The adhesive backing 300 may also be used to seal and waterproof the gap between the back cover 20 and the frame 1. Exemplarily, the back cover 20 may include a first surface 201, a second surface 202, and a peripheral side surface 203. The first surface 201 and the second surface 202 are disposed opposite to each other, with the first surface 201 being the surface of the back cover 20 facing the interior of the electronic device 1000. The second surface 202 is the surface of the back cover 20 away from the screen 200, i.e., the outer surface of the back cover 20. The peripheral side surface 203 connects between the first surface 201 and the second surface 202. An adhesive backing 300 may be provided between the first surface 201 of the back cover 20 and the boss 122, and the boss 122 and the back cover 20 may be fixedly connected by the adhesive backing 300. Understandably, compared to the solution where the adhesive 300 is fixedly connected between the frame 1 and the peripheral side surface 203 of the back cover 20, this embodiment places the adhesive 300 between the boss 122 and the first surface 201 of the back cover 20. The area of ​​the first surface 201 of the back cover 20 is larger than that of the peripheral side surface 203 of the back cover 20, allowing for a larger bonding area between the adhesive 300 and the frame 1 and the back cover 20, which is beneficial to improving the connection strength between the back cover 20 and the frame 1. Furthermore, the larger bonding area between the adhesive 300 and the frame 1 and the back cover 20 is beneficial to the reliability of the adhesive 300's sealing and waterproofing. External moisture and dust are less likely to enter the internal space of the electronic device 1000 through the gap between the back cover 20 and the frame 1, thus preventing corrosion of the internal components of the electronic device 1000.

[0075] In some embodiments, the second part 12 can be a plastic part, and the second part 12 and the first part 11 can be an integrally molded structural component. Here, an integrally molded structural component means that the two components are obtained through an integral molding process, whereby the component is connected to the other component during the formation of one of the components, without requiring further processing (such as bonding, welding, snap-fit ​​connections, or screw connections) to connect the two components together. For example, the second part 12 can be injection molded onto the first part 11, and can be fixedly connected to the first part 11 during the molding process of the second part 12. During the preparation of the frame 1, no additional process is required to assemble the second part 12 and the first part 11.

[0076] In some embodiments, the frame 1 and the back cover 20 can be integrally formed structural components. For example, combined with... Figure 2As shown, the first part 11 may include a plurality of first segments 111 and a plurality of second segments 112 arranged circumferentially along the frame 1. The first segments 111 are used to provide button mounting holes 105, card slots 106, or sound outlets 107. The second segments 112 may be connected between two adjacent first segments 111. There may be a gap 30 between the second segments 112 of the first part 11 and the back cover 20, and at least a portion of the second part 12 may fill the gap 30. The first segments 111 and the back cover 20 may be integrally formed structural components. In this way, the connection strength between the first part 11 and the back cover 20 is better. It is understood that in the manufacturing process of the housing 100 of the electronic device 1000, the first part 11 and the back cover 20 of the frame 1 may be integrally formed by metal processing technology first, and then the second part 12 may be formed on the first part 11 by processes such as insert injection molding, so as to obtain a housing 100 that includes both metal and non-metal materials. It is understood that the positions of the first segment 111 and the second segment 112 on the border 1 can be on any one or more of the first short side 101, the second short side 102, the first long side 103, and the second long side 104. This application does not impose any restrictions in this regard. The number of first segments 111 and the number of second segments 112 can be one or more.

[0077] In some embodiments, the end face 125 of the second portion 12 away from the screen 200 and the second surface 202 of the rear cover 20 have no step difference or a small step difference at the connection position. Thus, the end face 125 of the second portion 12 away from the screen 200 and the surface of the rear cover 20 away from the screen 200 smoothly transition at the connection point. During the manufacturing process of the housing 100, due to limitations in process precision and assembly tolerances, it is difficult to achieve a step difference of 0 between the end face 125 of the second portion 12 away from the screen 200 and the second surface 202 of the rear cover 20 at the connection position. A smooth transition at the connection point can be achieved even with a small step difference; for example, the step difference between the end face 125 of the second portion 12 away from the screen 200 and the second surface 202 of the rear cover 20 can be in the range of -0.1 mm to +0.1 mm. For example, the step difference between the end face 125 of the second part 12 away from the screen 200 and the second surface 202 of the back cover 20 can be -0.1mm, -0.8mm, -0.5mm, -0.2mm, 0mm, 0.2, 0.5mm, 0.8mm, 0.1mm, etc. It is understood that the second part 12 connects the first part 11 and the back cover 20. At the connection point, there is no step difference, or a small step difference, between the end face 125 of the second part 12 away from the screen 200 and the second surface 202 of the back cover 20. The outer surface of the housing 100 is relatively flat near the gap 30, without protrusions or large step differences. The housing 100 has a good appearance, and users do not experience any obvious steps or scratches when touching it, resulting in a better user experience.

[0078] Figure 6 yes Figure 3 The diagram shows a partial structural view of one embodiment of the back cover 20 from another angle.

[0079] like Figure 3 and Figure 6 As shown, the electronic device 1000 may further include a hook 400. The hook 400 can be fixedly connected to the inner surface of the rear cover 20, that is, the first surface 201 of the rear cover 20. Exemplarily, the hook 400 and the rear cover 20 are integrally formed structural components. It can be understood that, compared to the assembly scheme of the hook 400 and the rear cover 20 by welding, in this embodiment the hook 400 and the rear cover 20 are integrally formed, the rear cover 20 is less likely to have appearance marks, and the appearance of the housing 100 can be more refined. In addition, the rear cover 20 and the hook 400 do not require additional assembly steps, and the connection strength between the two is better.

[0080] It is understandable that there can be one or more hooks 400. When there are multiple hooks 400, they can be arranged at intervals along the circumference of the back cover 20. Figure 6 The diagram illustrates that electronic device 1000 includes four latches 400.

[0081] For example, the hook 400 can be made of a metallic material. The hook 400 has good strength. For example, materials such as aluminum, titanium, and stainless steel.

[0082] In other embodiments, the hook 400 can also be fixedly connected to the first surface 201 of the rear cover 20 by processes such as adhesive bonding or welding.

[0083] Figure 7 yes Figure 3 The diagram shows a structural schematic of one embodiment of the middle frame 10 from another angle. Figure 8 yes Figure 7 A schematic diagram of one embodiment of the first portion 11 of the middle frame 10 shown. Figure 7 In the enlarged portion of the image, fill the second part 12 with a fill pattern to distinguish it from the first part 11.

[0084] like Figure 7 and Figure 8As shown, near the antenna slot 1101, a bonding structure 40 can be provided at the joint between the first part 11 and the second part 12. Exemplarily, the distance between the bonding structure 40 and the second segment 112 of the first part 11 is less than the distance between the bonding structure 40 and the first segment 111 of the first part 11. The bonding structure 40, also known as a mechanical interlocking structure or adhesive composite structure, is a method of firmly connecting plastic and metal through a physical structure in the injection molding process. This structure can improve the bonding strength and avoid problems such as low bonding strength and slow bonding speed that occur in traditional adhesive bonding methods. (Comparison...) Figure 7 and Figure 8 A magnified view of a portion of the image. Figure 7 and Figure 8 The magnified view shows the same location within border 1. Figure 8 The diagram only shows the first part 11 of the frame 1. The surface of the first part 11 that contacts the second part 12 can be provided with grooves or protrusions, so that the contact surface of the first part 11 and the second part 12 is rough and uneven. During the forming process of the first part 11 and the second part 12, the contact area between the two is large and the friction on the connecting surface is large, so the connection strength between the first part 11 and the second part 12 is better.

[0085] It is understandable that there can be multiple adhesive-bonded structures 40, and these multiple adhesive-bonded structures 40 can be arranged along the circumference of the frame 1. At the location where the antenna slot 1101 is provided, more adhesive-bonded structures 40 can be provided to enhance the bonding strength between the first part 11 and the second part 12.

[0086] In some embodiments, the middle plate 2 of the middle frame 10 may also include a third part 21 made of metal and a fourth part 22 made of non-metallic material. Figure 7 The third part 21 is distinguished from the fourth part 22 by using a filling pattern to fill the third part 21. The third part 21 can be integrally formed with the first part 11. The fourth part 22 can be integrally formed with the second part 12. It is understood that during the preparation of the middle frame 10, the first part 11 and the third part 21 made of metal can be prepared first, and then the second part 12 and the fourth part 22 can be formed on the first part 11 and the third part 21 by injection molding or other processes. In this way, no additional assembly steps are required to connect the middle plate 2 and the frame 1.

[0087] In other embodiments, the middle plate 2 can also be fixedly connected to the frame 1 by welding or gluing, and this application does not impose any restrictions.

[0088] Figure 9 yes Figure 7 The diagram shows a partial structural schematic of one embodiment of the middle frame 10 shown from another angle. Figure 10 yes Figure 1 A partial cross-sectional view of one embodiment of the electronic device 1000 shown at another angle at CC. Figure 11 yes Figure 10 The diagram shown is a schematic representation of the structure from another angle.

[0089] like Figure 7 , Figure 9 and Figure 10 As shown, the second part 12 may be provided with a limiting groove 124. The opening of the limiting groove 124 may face the interior of the electronic device 1000. The limiting groove 124 is used to engage with the hook 400. Exemplarily, the limiting groove 124 may be located on the boss 122 of the second part 12. Exemplarily, the second part 12 may have a third surface 126 and a fourth surface 127. The third surface 126 faces the interior of the electronic device 1000, and the fourth surface 127 faces the rear cover 20. The limiting groove 124 may be located on the third surface 126. In this way, at least a portion of the second part 12 can limit the hook 400 in the thickness direction of the electronic device 1000.

[0090] It is understandable that the number of limit slots 124 can be one or more. For example... Figure 7 and Figure 9 As shown, four limiting slots 124 are provided on the middle frame 10. Among them, two limiting slots 124 are located on the first short side 101, and the other two limiting slots 124 are located on the second short side 102. This application does not limit the number and position of the limiting slots 124. In other embodiments, limiting slots 124 may also be provided on the first long side 103 and / or the second long side 104.

[0091] like Figure 10 and Figure 11 As shown, the hook 400 can engage within the limiting groove 124. It can be understood that by setting the hook 400 and the limiting groove 124 to cooperate, the hook 400 and the back cover 20 are fixedly connected. The hook 400 engaging within the limiting groove 124 can limit the relative positioning of the back cover 20 and the middle frame 10. For example, it can reduce the relative movement of the back cover 20 relative to the middle frame 10 in the XY plane. Since the back cover 20 is made of metal and the second part 12 of the middle frame 10 is made of rubber, the hardness of the metal back cover 20 is greater than that of the rubber second part 12. When the electronic device is subjected to mechanical environments such as drops, the cooperation between the hook 400 and the limiting groove 124 can reduce the impact of the back cover 20 on the second part 12, reducing the risk of damage to the second part 12 from the impact of the back cover 20. This allows the second part 12 to better fill the gap 30.

[0092] For example, along the X-axis direction, both sides of the hook 400 have the groove walls of the limiting groove 124, which can limit the movement of the rear cover 20 in the X-axis direction.

[0093] For example, along the Y-axis direction, the groove wall of the limiting groove 124 is located on the side of the hook 400 facing the outside of the electronic device 1000. The limiting groove 124 can limit the tendency of the back cover 20 to move towards the outside of the electronic device 1000 in the X-axis direction. Along the direction from the first short side 101 to the second short side 102, at least two hooks 400 are arranged at intervals, that is, at least one hook 400 is engaged with the first short side 101 and at least one hook 400 is engaged with the second short side 102. The cooperation of the two hooks 400 can limit the movement of the back cover 20 in the Y-axis direction.

[0094] For example, along the Z-axis direction, both sides of the hook 400 have groove walls of the limiting groove 124, which can limit the movement of the rear cover 20 in the Z-axis direction.

[0095] Understandable Figure 10 and Figure 11 This illustration only shows one embodiment of the hook 400. In other embodiments, the hook 400 may also engage with the first long side 103 and / or the second long side 104. The specific way the hook 400 engages with the frame 1 can be adapted by those skilled in the art according to actual needs.

[0096] It is understood that, without conflict, the embodiments and features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0097] It is understood that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.

[0098] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
