[0061] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0062] Inside the terminal device, it is necessary to limit the electronic components on the motherboard of the terminal device in the thickness direction.

[0063] In related technologies, refer to Figure 1 Typically, a large-area back shell solution is used. For example, it can be a large-area back shell composed of plastic a and metal b, or it can be an all-plastic solution, or it can be a solution that fixes the plastic layer through the sound cavity (SPK BOX).

[0064] However, the heights of electronic components on the motherboard vary, as do the heights of board-to-board (BTB) connectors. Therefore, it is necessary to ensure that the tallest electronic components are effectively limited and to meet the actual processing capabilities of the supporting materials. This results in the back cover of the terminal device being very thick and heavy, making the whole device bulky and affecting the user experience.

[0065] To address the aforementioned issues, this disclosure provides a terminal device comprising a motherboard body, a first chip, and a limiting component. The motherboard body has a first antenna spring, and the first chip covers the first antenna spring. The limiting component includes a first cover plate, which covers the first chip and is securely connected to the motherboard body, thereby pressing the first chip and subsequently the first antenna spring. In this disclosure, by using the first cover plate to press the first chip, sufficient pressure is created between the first chip and the first antenna spring, ensuring stable triggering of the first antenna spring. Furthermore, by distributing the limiting component, which limits various structures on the motherboard body, into smaller, modular components, the overall thickness of the terminal device is reduced, facilitating a thinner and lighter design and improving the user experience.

[0066] According to an exemplary embodiment, such as Figure 2 As shown, this embodiment provides a terminal device 100, which can be an electronic device such as a smartphone or tablet computer, and the terminal device can have a foldable screen and folding function.

[0067] The internal structure of the terminal device shown in the embodiments of this disclosure does not limit the technical solution of this disclosure. It is understood that the internal structures of electronic devices produced by different manufacturers are different, and even the internal structures of different models of electronic devices produced by the same manufacturer are not the same.

[0068] In this embodiment, as Figure 2 and Figure 3 As shown, the terminal device 100 includes a motherboard body 10 and a first chip 20. (Referring to...) Figure 2 The motherboard body 10 supports and mounts various electronic components, enabling electrical connections or insulation between these components. These electrical components include antenna springs, the core processor, various controllers, and interfaces for cameras, speakers, microphones, and display screens. (Refer to...) Figure 2 The antenna spring includes a first antenna spring 11, which may be, for example, a contact spring of an NFC antenna.

[0069] Among them, reference Figure 3 The first chip 20 is included in the aforementioned electronic components. The first chip 20 can cover the first antenna spring 11, thereby enabling the first chip 20 to form an electrical connection with the first antenna spring 11.

[0070] It should be noted that, under normal circumstances, the first antenna spring 11 needs to be subjected to a certain degree of pressure to activate and function. Therefore, sufficient pressure is required between the first chip 20 and the first antenna spring 11 to ensure that the first chip 20 can function properly. In this embodiment, as... Figure 2 and Figure 4 As shown, the terminal device 100 also includes a limiting component 30, which includes a first cover plate 31. The first cover plate 31 covers the first chip 20 and is fastened to the motherboard body 10 so that the first cover plate 31 presses against the first chip 20 and in turn presses against the first antenna spring 11. The material of the first cover plate 31 can be non-metallic, such as plastic (plastic has excellent mechanical properties, electrical properties, heat resistance, chemical resistance, and dimensional stability). Using plastic material to make the first cover plate 31 can, on the one hand, give the first chip 20 a sufficiently large clearance area, reducing the reduction of antenna performance caused by metal shielding; on the other hand, the low density of plastic can reduce the weight of the electronic device.

[0071] Reference Figure 4 Viewed along the thickness direction of terminal device 100 ( Figure 4 (as shown in the z direction), the shape of the first cover plate 31 can be rectangular, circular or irregular, etc. In practical applications, the shape of the first cover plate 31 is mostly irregular, so that it can avoid or limit other electronic components on the motherboard body 10.

[0072] Reference Figure 4 The first cover plate 31 can be securely connected to the motherboard body by means of fastener connection, snap-fit ​​structure, bonding, welding, etc. This embodiment exemplarily illustrates a fastener connection scheme, where the fastener can be a screw. The motherboard body 10 has a through hole (not shown), the first cover plate 31 has a through hole (not shown), and the middle frame 90 has a threaded hole. When assembling the first cover plate 31, the through holes on the first cover plate 31 and the motherboard body 10 are aligned with the threaded hole on the middle frame 90. After the fastener passes through the through holes on the first cover plate 31 and the motherboard body 10, it engages with the threaded hole on the middle frame 90, thereby pressing the first cover plate 31 tightly, thus achieving a secure connection of the first cover plate 31 in the thickness direction of the terminal device. Figure 4 Locking positioning in the z-direction shown in the diagram.

[0073] In this embodiment, by setting a first cover plate to squeeze the first chip, sufficient pressure is applied between the first chip and the first antenna spring to ensure stable triggering of the first antenna spring. Since the limiting components used to limit the various structures on the motherboard are divided into smaller, modular components, the overall thickness of the terminal device is reduced, which is conducive to achieving a thinner and lighter body and improving the user experience.

[0074] In one exemplary embodiment, such as Figure 2 As shown, Figure 2 A terminal device 100 is shown. The terminal device 100 includes a motherboard body 10, a first chip 20, and a limiting component 30. The motherboard body 10 is provided with a first antenna spring 11. The first chip 20 covers the first antenna spring 11. The limiting component 30 includes a first cover plate 31. The first cover plate 31 covers the first chip 20 and is fastened to the motherboard body 10 so that the first cover plate 31 squeezes the first chip 20 and thus squeezes the first antenna spring 11.

[0075] In this embodiment, refer to Figures 2 to 4 The first side of the first chip ( Figure 3 A first circuit board 40 is provided in the x-direction shown. The first circuit board 40 can connect the main board body 10 and a small board (not shown), which is usually located at the bottom of the terminal device 100. Figure 3(In the opposite direction of the y-direction shown), various types of electronic components can also be installed on the small board, which will not be elaborated here. The main board body 10 is provided with a connector 41 for the first circuit board. The connector 41 of the first circuit board 40 and the first circuit board can be connected in a board-to-board (BTB) manner. In the assembled state, the first cover plate 31 can cover and press the connector 41 of the first circuit board, so that the first cover plate 31 can be positioned in the thickness direction of the terminal device 100 (in the opposite direction of the y-direction). Figure 4 The first circuit board 40 is limited in the z direction shown in the figure.

[0076] Reference Figure 3 The second side of the first chip 20 ( Figure 3 The first end 12a of the first set of terminals is set in the y direction shown in the figure.

[0077] In one example, the first set of terminal blocks 12 may include a first terminal block 121 (antenna ANT6) and a second terminal block 122 (antenna ANT2). In the assembled state, the first cover plate 31 covers and presses the first end 12a of the first set of terminal blocks, so that the first terminal block 121 and the second terminal block 122 are more stably connected to the first set of terminal blocks 12, and the first terminal block 121 and the second terminal block 122 are prevented from falling off the first set of terminal blocks 12.

[0078] Reference Figure 3 The third side of the first chip 20 ( Figure 3 The first camera 50 is set up (in the opposite direction of the x-direction shown in the diagram). The first camera 50 can be, for example, a main camera lens, a telephoto lens, an ultra-wide-angle lens, a macro lens, etc. (Refer to...) Figure 4 The first cover plate 31 is provided with a first support arm 311 that bends relative to the first cover plate 31, and the first support arm 311 is in the thickness direction of the terminal device 100. Figure 4 The first arm 311 is positioned higher than the first camera 50 in the z-direction shown in the diagram, so that the first arm 311 can press against the first camera 50.

[0079] Reference Figure 4 A sensor (not shown) and a preset circuit board 37 are disposed on the side of the first cover plate 31 opposite to the first chip 20. The preset circuit board 37 can be equipped with a sensor, such as a flash image sensor or a flicker sensor.

[0080] Among them, such as Figure 4 As shown, the terminal device 100 includes a second camera 60. The second camera 60 and the first camera 50 can be cameras of different types; the type of the second camera is not limited here. (See reference...) Figure 3 , Figure 5 and Figure 6The motherboard body 10 is provided with a first mounting bracket 13, which is used to mount the second camera 60. The first mounting bracket 13 is provided with positioning ribs 131, which can fix the second camera 60 in the first mounting bracket 13. (Refer to...) Figure 6 The first mounting bracket 13 is provided with a second arm 132. Multiple second arms 132 can be provided. Multiple second arms 132 are bent relative to the first mounting bracket 13 towards the side away from the second camera 60 (that is, the second arms 132 can extend in the horizontal direction (perpendicular to the z direction), that is, some second arms 132 extend along the x direction and some second arms 132 extend along the y direction). The second arms 132 can be snapped into the motherboard body 10, so that the first mounting bracket 13 is securely connected to the motherboard body 10.

[0081] Reference Figures 3 to 5 The wiring of the first set of connectors 12 (first connector 121 and second connector 122) passes through the second arm 132, and the first connector 121 and second connector 122 press against the second arm 132. It should be noted that the first connector 121 and second connector 122 are located on the side of the second arm 132 away from the motherboard body 10. The first connector 121 and second connector 122 are limited by the first cover plate 31 in the z direction, so that the first connector 121 and second connector 122 can press against the second arm 132 in the z direction to fix the first mounting bracket 13.

[0082] In one example, refer to Figure 4 and Figure 5 The limiting component 30 also includes a hook 33, which is disposed on the motherboard body 10. The hook 33 bends relative to the motherboard body 10 toward the first wire 121 and the second wire 122 of the first set of connectors 12, so that the hook 33 can squeeze the connecting wires of the first set of connectors to enhance the limiting reliability of the first wire 121 and the second wire 122 on the second arm 132 of the first mounting bracket 13.

[0083] In one exemplary embodiment, such as Figure 2 As shown, Figure 2 A terminal device 100 is shown. The terminal device includes a motherboard body 10, a first chip 20, and a limiting component 30. The motherboard body 10 is provided with a first antenna spring 11. The first chip 20 covers the first antenna spring 11. The limiting component 30 includes a first cover plate 31. The first cover plate 31 covers the first chip 20 and is fastened to the motherboard body 10 so that the first cover plate 31 squeezes the first chip 20 and thus squeezes the first antenna spring 11.

[0084] In this embodiment, as Figures 2 to 4As shown, the terminal device 100 includes a third camera 70 disposed on the motherboard body 10. The third camera 70, the first camera 50, and the second camera 60 can be cameras of different types. (Refer to...) Figure 2 , Figure 7 , Figure 8 and Figure 9 The limiting component 30 includes a second mounting bracket 34, which is fixedly connected to the motherboard body 10. The second mounting bracket 34 can be connected to the motherboard body 10 by fasteners, adhesives, or other means. The second mounting bracket 34 includes a third arm 3411, which is snapped into the third camera 70, limiting the third camera 70 along the thickness direction of the terminal device 100. Figure 2 The displacement in the z-direction shown in the figure.

[0085] In one example, refer to Figures 7 to 9 The second mounting bracket 34 includes a bracket body 341 and a limiting part 342. The limiting part 342 is fixedly disposed on the motherboard body 10. The limiting part 342 and the motherboard body 10 can be integrally formed or welded together. The bracket body 341 is connected to the motherboard body 10, and a third support arm 3411 is formed on the bracket body 341. The bracket body 341 is provided with a limiting hole 3412. In the assembled state, the limiting part 342 on the motherboard body 10 can pass through the limiting hole 3412 of the second mounting bracket 34. It should be noted that in practical applications, in order to reduce the area occupied by the second mounting bracket 34 on the motherboard body 10, the bracket body 341 of the second mounting bracket 34 is usually connected to the motherboard body 10 using only a single fastener (screw). Therefore, a limiting hole 3412 is provided on the bracket body 341. The limiting hole 3412 cooperates with the limiting part 342 to restrict the rotation of the bracket body 341 relative to the fastener.

[0086] Reference Figure 7 The limiting part 342 is fixedly disposed on the motherboard body 10, and the bracket body 341 is fixed to the motherboard body 10 by adhesive connection. The bracket body 341 is fastened to the motherboard body 10 by fasteners. In one example, double-sided adhesive (not shown) can be provided between the bracket body 341 and the motherboard body 10 to fix the bracket body 341 and the motherboard body 10. This fixation can be pre-fixed, and fasteners can be used later to form a more stable fastening connection between the bracket body 341 and the motherboard body 10.

[0087] In one exemplary embodiment, such as Figure 2 As shown, Figure 2A terminal device is shown. The terminal device 100 includes a motherboard body 10, a first chip 20, and a limiting component 30. The motherboard body 10 is provided with a first antenna spring 11. The first chip 20 covers the first antenna spring 11. The limiting component 30 includes a first cover plate 31. The first cover plate 31 covers the first chip 20 and is fastened to the motherboard body 10 so that the first cover plate 31 squeezes the first chip 20 and thus squeezes the first antenna spring 11.

[0088] In this embodiment, as Figure 2 , Figure 10 and Figure 11 As shown, the motherboard body 10 is provided with a second antenna spring 14, which is grounded. The limiting component 30 includes a second cover plate 32, which covers and presses the second antenna spring 14.

[0089] Reference Figure 2 , Figure 10 and Figure 11 The terminal device 100 includes a middle frame 90, a first positioning part 91 disposed on the middle frame 90, and a second positioning part 321 disposed on the second cover plate 32. The first positioning part 91 and the second positioning part 321 cooperate to position the second cover plate 32. In one example, refer to... Figure 4 and Figure 10 The first positioning part 91 can be a cylinder protruding from the main body 10, and the second positioning part 321 can be a through hole penetrating the second cover plate 32 in the z direction, with the inner diameter of the through hole being equal to the outer diameter of the cylinder. When assembling the second cover plate 32, the first positioning part 91 and the second positioning part 321 can be engaged to fix the second cover plate 32.

[0090] Reference Figure 10 The second cover plate 32 can be securely connected to the motherboard body 10 by multiple fasteners. The fasteners can be screws, and the second cover plate 32 can also be connected to the motherboard body 10 by means of clips, welding, etc.

[0091] In one exemplary embodiment, such as Figure 2 As shown, Figure 2 A terminal device is shown. The terminal device 100 includes a motherboard body 10, a first chip 20, and a limiting component 30. The motherboard body 10 is provided with a first antenna spring 11. The first chip 20 covers the first antenna spring 11. The limiting component 30 includes a first cover plate 31. The first cover plate 31 covers the first chip 20 and is fastened to the motherboard body 10 so that the first cover plate 31 squeezes the first chip 20 and thus squeezes the first antenna spring 11.

[0092] In this embodiment, as Figure 2As shown, the motherboard body is provided with a flexible printed circuit (FPC) and a connector for connecting the flexible printed circuit. The connector in this embodiment can be a board-to-board (BTB) connector.

[0093] Reference Figure 2 , Figure 4 and Figure 13 The limiting component 30 includes a clamping member, which is connected to the connector and securely connected to the motherboard body via fasteners. Understandably, when using plastic to manufacture the limiting component, the technical limitations of plastic materials result in a relatively thick thickness, while the height of electronic components in the terminal device ( Figure 2 The difference in the z-direction (as shown in the diagram) makes it impossible to use plastic parts to limit the height of electronic components. The clamping component can be made of materials such as metal or high-strength non-metallic materials to ensure sufficient strength and improve installation reliability. It should also be thin while maintaining high strength, reducing the clamping component's footprint in the thickness direction of the terminal device and facilitating a slimmer, lighter design.

[0094] Among them, such as Figure 2 and Figure 4 As shown, the terminal device 100 includes a first camera 50 and a second camera 60. The first camera 50 and the second camera 60 have been described in the preceding embodiments and will not be repeated here. The limiting component 30 includes a first clamping member 351. The first clamping member 351 is fastened to the connector 51 of the first camera and the connector 61 of the second camera respectively by fasteners. The fasteners can provide pressure to the first clamping member 351, causing the first clamping member 351 to exert pressure on the connector 51 of the first camera and the connector 61 of the second camera, so as to exert pressure in the thickness direction of the terminal device 100. Figure 2 Limiting is performed in the z-direction shown in the diagram.

[0095] Reference Figure 2 and Figure 4 The terminal device 100 includes a middle frame 90, a third positioning part 92 is provided on the middle frame 90, and a fourth positioning part (not shown) is provided on the first clamping member 351. The third positioning part 92 and the fourth positioning part cooperate to position the first clamping member 351. In one example, refer to... Figure 4 The third positioning part 92 can be a cylinder protruding from the motherboard body 10, and the fourth positioning part can be a through hole penetrating the first clamping member 351 in the z direction.
