Terminal structural components and terminal equipment

[0001] This application claims priority to the Chinese patent application with application number 202410323433.4 filed with the State Intellectual Property Office of China on March 18, 2024, and priority to the Chinese patent application with the invention name “Terminal structural components and terminal equipment”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of electronic technology, and in particular to a terminal structural component and a terminal device. Background Art

[0003] With the rapid development of terminal devices equipped with cameras, requirements have been put forward for both the imaging quality of cameras and the portability of terminal devices. In order to improve the imaging quality of cameras, the optical system of the camera usually needs to have a longer optical length, resulting in an increase in the overall length of the camera. In order to improve the portability of terminal devices, it is usually necessary to reduce the thickness of the terminal device. When the camera is installed on the terminal device, the length direction of the camera and the thickness direction of the terminal device are the same. Terminal devices with smaller thicknesses are more difficult to accommodate cameras with larger total lengths. Terminal devices equipped with cameras with better imaging quality have a larger thickness, which reduces their portability. It is necessary to make a trade-off between the portability of the terminal device and the imaging quality of the camera.

[0004] Summary of the Invention

[0005] The present application provides a terminal structure assembly and a terminal device. By setting a through hole at the first cover plate, the lens assembly is partially located in the through hole, so that the lens assembly and the cover plate assembly partially overlap in the thickness direction, thereby reducing the overall thickness of the lens assembly and the cover plate assembly, and achieving a lightweight and thin terminal device while ensuring that the length of the lens assembly remains unchanged.

[0006] In the first aspect, the present application provides a terminal structure assembly, including: a lens assembly, the optical axis direction of the lens assembly is a first direction; a middle frame, having a receiving groove, and part of the lens assembly is located in the receiving groove; a cover plate assembly, including a first cover plate and a second cover plate, at least a part of the middle frame, at least a part of the first cover plate and a part of the second cover plate are connected in sequence in the first direction, the first cover plate has a through hole, the through hole is connected to the receiving groove, part of the lens assembly is located in the through hole, the second cover plate closes the through hole, and the lens assembly is located between the second cover plate and the bottom wall of the receiving groove.

[0007] The terminal structure assembly provided in the present application includes a lens assembly, a middle frame, and a cover plate assembly. The middle frame has a receiving groove, and part of the lens assembly is located in the receiving groove. The lens assembly is fixed to the bottom wall of the receiving groove, so that the middle frame supports and fixes the lens assembly, ensuring the stability of the position of the lens assembly relative to the middle frame. The cover plate assembly includes a first cover plate and a second cover plate. The middle frame, the first cover plate, and the second cover plate are connected in sequence in a first direction. At least a portion of the middle frame is connected to at least a portion of the first cover plate, and at least a portion of the first cover plate is connected to a portion of the second cover plate. This is conducive to ensuring the connection area between the first cover plate and the middle frame, and the second cover plate and the first cover plate, thereby improving the stability of the connection structure between the middle frame and the cover plate assembly. The cover plate assembly and the middle frame have strong impact resistance, thereby ensuring the protection ability of the cover plate assembly and the middle frame for the lens assembly. The cover plate assembly closes the opening of the receiving groove, and the cover plate assembly and the bottom wall of the receiving groove clamp the lens assembly, further achieving the fixation of the position of the lens assembly.

[0008] The first cover plate has a through hole, and the second cover plate is connected to the first cover plate and closes the through hole, thereby ensuring the first cover plate and the second cover plate's ability to protect the lens assembly. At the same time, the first cover plate and the second cover plate are connected so that external impact forces on the cover plate assembly can be dispersed to the first cover plate and the second cover plate, thereby improving the cover plate assembly's impact resistance. A portion of the lens assembly extends from the opening of the accommodating groove in the first direction and is located within the through hole, so that the length of the lens assembly and the thickness of the first cover plate partially overlap in the first direction. Under the premise that the terminal structure assembly can accommodate the lens assembly, the thickness of the terminal structure assembly in the first direction is reduced, which is conducive to achieving a lightweight and thin terminal structure assembly and improving the portability of the terminal structure assembly.

[0009] In one possible embodiment, the first cover plate has an outer surface, which is the surface of the first cover plate facing away from the middle frame in the first direction. The outer surface has a first groove, which surrounds the through hole and is in communication with the through hole. The first groove is used to accommodate the second cover plate, and the second cover plate is connected to the bottom wall of the first groove. By providing the first groove on the outer surface of the first cover plate to accommodate the second cover plate, the thickness of the second cover plate and the depth of the first groove in the first direction at least partially overlap, that is, the thickness of the second cover plate and the thickness of the first cover plate at least partially overlap in the first direction. This reduces the thickness of the cover plate assembly in the first direction, that is, reduces the thickness of the terminal structure assembly in the first direction, and thus facilitates the thinning and lightweight of the terminal structure assembly.

[0010] In one possible embodiment, the outer surface has a protrusion that surrounds the periphery of the first groove. By providing the outer surface of the first cover plate with a protrusion that surrounds the periphery of the first groove, the protrusion can limit the position of the second cover plate in a direction perpendicular to the first direction, thereby improving the stability of the second cover plate's position.

[0011] In one possible embodiment, in the first direction, the height of the second cover plate relative to the bottom wall of the first groove is less than or equal to the height of the protrusion relative to the bottom wall of the first groove. By ensuring that the height of the second cover plate relative to the bottom wall of the first groove in the first direction is less than or equal to the height of the protrusion relative to the bottom wall of the first groove, the second cover plate is completely accommodated within the first groove, and the sidewalls of the first groove have a better effect of limiting the position of the second cover plate, which helps to improve the stability of the second cover plate's position.

[0012] In one possible embodiment, the middle frame includes a first middle frame and a second middle frame, the first middle frame and the second middle frame are rotatably connected, the first middle frame has the receiving groove, the first cover plate includes a main cover plate and a secondary cover plate, the main cover plate is connected to the first middle frame, the main cover plate has the protrusion, the secondary cover plate is connected to the second middle frame, the secondary cover plate has a receiving groove, and the receiving groove is used to accommodate the protrusion. By making the middle frame include a first middle frame and a second middle frame that are rotatably connected, the first cover plate includes a main cover plate and a secondary cover plate, the main cover plate is connected to the first middle frame, the secondary cover plate is connected to the second middle frame, the main cover plate has the protrusion, and the secondary cover plate has the receiving groove, so that when the first middle frame and the second middle frame are relatively rotated to a folded state, the receiving groove can accommodate the protrusion, which is beneficial to reducing the thickness of the terminal structure assembly in the first direction when the middle frame is in the folded state, thereby achieving miniaturization of the terminal structure assembly.

[0013] In one possible embodiment, the terminal structure assembly further includes a connector, and the first and second middle frames are rotatably connected via the connector. When the first and second middle frames are in a folded state, the receiving groove accommodates the protrusion. By including the connector in the terminal structure assembly, the first and second middle frames can rotate relative to each other about the connector, thereby simplifying the relative rotation process of the first and second middle frames. Furthermore, when the first and second middle frames are rotated and folded, the receiving groove accommodates the protrusion, reducing the thickness of the terminal structure assembly in a first direction and achieving miniaturization of the terminal structure assembly.

[0014] In one possible embodiment, in the first direction, the distance between the bottom wall of the first groove and the outer surface is less than the height of the second cover plate relative to the bottom wall of the first groove. By ensuring that the distance between the bottom wall of the first groove and the outer surface is less than the height of the second cover plate relative to the bottom wall of the first groove in the first direction, the second cover plate protrudes relative to the outer surface of the first cover plate in the first direction, and the depth of the first groove in the first direction can be appropriately reduced, so that the first cover plate has a certain thickness at the first groove, thereby ensuring the structural strength of the first cover plate at the first groove, and the first cover plate has strong impact resistance, which is conducive to ensuring the protective ability of the cover plate assembly for the lens assembly.

[0015] In one possible embodiment, in the first direction, the thickness of the second cover plate is less than that of the first cover plate, and the hardness of the second cover plate is greater than that of the first cover plate. By making the thickness of the second cover plate less than that of the first cover plate and the hardness of the second cover plate greater than that of the first cover plate, the thickness of the second cover plate is reduced, thereby facilitating the first groove to accommodate and limit the second cover plate. At the same time, the second cover plate has a certain structural strength despite its small thickness. While reducing the thickness of the cover plate assembly in the first direction, the cover plate assembly's ability to protect the lens assembly is ensured.

[0016] In one possible embodiment, in the first direction, the surface of the middle frame facing the first cover plate has a second groove, the second groove surrounds the opening of the accommodating slot, the second groove is connected to the accommodating slot, the second groove is used to accommodate the first cover plate, and the first cover plate is connected to the bottom wall of the second groove. By providing the second groove on the surface of the middle frame facing the first cover plate, the second groove surrounds the opening of the accommodating slot, and the second groove accommodates the first cover plate, the thickness of the first cover plate and the depth of the second groove at least partially overlap in the first direction. That is, the thickness of the first cover plate and the thickness of the middle frame at least partially overlap in the first direction, thereby reducing the thickness of the terminal structural assembly in the first direction and facilitating a thinner and lighter terminal structural assembly.

[0017] In one possible embodiment, the projection of the second cover plate in the first direction partially overlaps with the projection of the middle frame in the first direction. By partially overlapping the projection of the second cover plate in the first direction with the projection of the middle frame in the first direction, the middle frame can indirectly support the second cover plate in the first direction. Both the middle frame and the first cover plate support the second cover plate, which helps to improve the stability of the second cover plate's position.

[0018] In a second aspect, the present application further provides a terminal device comprising the terminal structure assembly described in any one of the embodiments of the first aspect and a screen, wherein at least a portion of the screen is connected to at least a portion of the middle frame in the first direction, and the screen is located on a side of the middle frame away from the cover assembly. The beneficial effects of this embodiment are similar to those of the above embodiments and are not further described in this embodiment.

[0019] In one possible embodiment, the bottom wall of the accommodating groove has a lens hole, the screen encloses the lens hole, and in the first direction, the surface of the screen facing the middle frame has a relief groove, the relief groove is connected to the lens hole, the lens assembly protrudes from the lens hole, and a portion of the lens assembly is located within the relief groove. By providing the bottom wall of the accommodating groove with a lens hole, the surface of the screen facing the middle frame with a relief groove, the relief groove is connected to the lens hole, the lens assembly protrudes from the lens hole, and a portion of the lens assembly is located within the relief groove, so that, while the terminal device can accommodate the lens assembly, the length of the lens assembly partially overlaps with the thickness of the relief groove in the first direction. The thickness of the terminal device in the first direction is reduced, and the thickness of the terminal device in the first direction is reduced, which is conducive to achieving a lighter and thinner terminal device and improving the portability of the terminal device.

[0020] In one possible embodiment, the terminal device further includes a speaker module, the speaker module is fixedly connected to the middle frame, the lens assembly has a bracket, the speaker module has a first abutting portion, the middle frame has a second abutting portion, and in the first direction, the bracket is located between the first abutting portion and the second abutting portion, the first abutting portion abuts against the bracket along the first direction, and the second abutting portion abuts against the bracket in the opposite direction of the first direction. By making the terminal device further include a speaker module, the speaker module is fixedly connected to the middle frame, the lens assembly has a bracket, the speaker module has a first abutting portion, and the middle frame has a second abutting portion, the first abutting portion and the second abutting portion respectively apply forces in opposite directions along the first direction to the bracket, so that the middle frame and the speaker module clamp and fix the lens assembly, which is beneficial to improving the stability of the lens assembly position.

[0044] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0045] For ease of understanding, the English abbreviations and related technical terms involved in the embodiments of this application are explained and described below.

[0046] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0047] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0048] It should be understood that the term "and / or" as used herein is simply a term used to describe the existence of three possible relationships between related objects. For example, "A and / or B" can represent the existence of A alone, the existence of both A and B, and the existence of B alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0049] The word "if," as used herein, may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to the determination" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)," depending on the context.

[0050] It should be understood that the terms “first”, “second”, etc. used in this application are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0051] In the description of this application, the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting this application.

[0052] In the description of this application, it should be noted that due to manufacturing errors or assembly errors, there are some angular deviations in the design that should be vertical or parallel. For example, the deviation is within 15 degrees, which also falls within the vertical or parallel described in this embodiment.

[0053] When used in this application, "within the range of...", unless it is specifically stated that the end value is not included, it is assumed that both end values ​​of the range are included. For example, in the range of 1 to 5, the two values ​​1 and 5 are included.

[0054] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a conflicting connection or an integrated connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0055] It should be understood that, in this application, "electrical connection" can be understood as physical contact and electrical conduction between components; it can also be understood as the connection between different components in a circuit structure through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit signals. "Connection" and "connected" can both refer to a mechanical or physical connection relationship. For example, "A and B are connected" or "A and B are connected" can mean that there is a fastening member (such as a screw, bolt, rivet, etc.) between A and B, or that A and B are in contact with each other and A and B are difficult to separate.

[0056] With the rapid development of terminal devices equipped with cameras, requirements have been put forward for the imaging quality of cameras and the portability of terminal devices.

[0057] In order to improve the imaging quality of the camera and provide a better photo-taking experience, the camera's optical system is required to have higher resolution and imaging quality. This usually requires increasing the number of lenses in the optical system or making the lenses in the optical system have a larger range of movement on the optical axis. These factors increase the total optical length of the optical system, ultimately leading to an increase in the total length of the camera.

[0058] To improve the portability of terminal devices and provide a better user experience, it is usually necessary to reduce the thickness of the terminal devices. When a camera is installed on a terminal device, the optical axis of the camera's optical system extends in the same direction as the thickness of the terminal device, making the length of the camera and the thickness of the terminal device the same. Thinner terminal devices are less likely to accommodate longer cameras. The minimum thickness of the terminal device is limited by the total length of the camera. As a result, terminal devices equipped with cameras with good imaging quality have a greater thickness, reducing their portability. A trade-off needs to be made between the portability of the terminal device and the imaging quality of the camera.

[0059] At the same time, in order to mount and protect the camera, a corresponding fixed structure is required to support and connect the camera, and a shell of a certain thickness is required to cover the camera to prevent damage to the camera when subjected to external impact forces and to achieve a protective effect on the camera. The provision of the fixed structure and shell further increases the thickness of the terminal device at the camera installation point, which is not conducive to meeting the demand for thin and lightweight terminal devices.

[0060] The present application provides a terminal structure assembly 100. Please refer to Figures 1, 2, and 3. Figure 1 shows a schematic structural diagram of the terminal structure assembly 100 according to an embodiment of the present application. Figure 2 shows a cross-sectional view of the terminal structure assembly 100 at point AA according to the embodiment shown in Figure 1. Figure 3 shows an enlarged view of the terminal structure assembly 100 at point a according to the embodiment shown in Figure 2. The terminal structure assembly 100 includes a lens assembly 30, a middle frame 20, and a cover assembly 10. The middle frame 20 has a receiving groove 21, and a portion of the lens assembly 30 is located within the receiving groove 21. The middle frame 20 supports and connects the lens assembly 30 to ensure the stability of the position of the lens assembly 30 relative to the middle frame 20, thereby achieving the fixation and protection of the lens assembly 30 by the middle frame 20. The cover assembly 10 is connected to a side surface of the middle frame 20 and is used to close the opening of the receiving groove 21. The lens assembly 30 is located between the cover assembly 10 and the middle frame 20.

[0061] Please refer to Figures 7, 8, and 11. Figure 7 shows a sectional perspective view of the terminal structure assembly 100 provided in the embodiment shown in Figure 1 at AA and a partial enlarged view thereof. Figure 8 shows an exploded view of the terminal structure assembly 100 provided in the embodiment shown in Figure 1. Figure 11 shows a schematic structural diagram of the middle frame 20 provided in the embodiment of the present application. When the lens assembly 30 is located in the accommodating groove 21, the middle frame 20 and the cover assembly 10 enclose the lens assembly 30, jointly protecting the lens assembly 30 and preventing the lens assembly 30 from being damaged when subjected to external impact forces. At the same time, a sealed space is formed inside the accommodating groove 21 to prevent external dust and other substances from entering the lens assembly 30 and affecting the imaging effect of the lens assembly 30.

[0062] The optical axis of lens assembly 30 is the axis of symmetry for each component in lens assembly 30. Lens assembly 30 includes a lens. The optical axis of lens assembly 30 passes through the center of the spherical surface of the lens and is perpendicular to the lens surface. At this spherical center point, no deflection occurs between the incident and outgoing light rays. When lens assembly 30 includes at least two lenses, the optical axis of lens assembly 30 passes through the center of the spherical surface of at least two lenses.

[0063] The direction of the optical axis of the lens assembly 30 is defined as the first direction, and the thickness of the middle frame 20 is aligned with the first direction. A side surface of the middle frame 20 in the first direction (e.g., the X direction in Figures 2 and 3) includes a receiving groove 21. A portion of the lens assembly 30 is positioned within the receiving groove 21. The lens assembly 30 is secured relative to the bottom wall of the receiving groove 21. A gap exists between the lens assembly 30 and the sidewalls of the receiving groove 21. This provides more space for the lens assembly 30 to be accommodated within the receiving groove 21, simplifies installation of the lens assembly 30 within the receiving groove 21, and helps prevent interference between the lens assembly 30 and the sidewalls of the receiving groove 21.

[0064] Please refer to Figures 3 and 4. Figure 4 shows an enlarged view of the terminal structure assembly provided by the embodiment shown in Figure 3 at point b. The cover plate assembly 10 includes a first cover plate 11 and a second cover plate 12. The first cover plate 11 is located on one side of the middle frame 20 in the first direction, and the second cover plate 12 is located on the side of the first cover plate 11 away from the middle frame 20 in the first direction. The middle frame 20, the first cover plate 11, and the second cover plate 12 are connected in sequence in the first direction. At least a portion of the middle frame 20 is connected to at least a portion of the first cover plate 11. The projection area of ​​the first cover plate 11 in the first direction is less than or equal to the projection area of ​​the middle frame 20 in the first direction. At the same time, the projection of the first cover plate 11 in the first direction is located within the projection range of the middle frame 20 in the first direction, or the projection of the first cover plate 11 in the first direction completely overlaps with the projection of the middle frame 20 in the first direction.

[0065] In one embodiment, the projection area of ​​the first cover plate 11 in the first direction is smaller than the projection area of ​​the middle frame 20 in the first direction. The projection of the first cover plate 11 in the first direction is within the projection range of the middle frame 20 in the first direction. In addition, in a direction perpendicular to the first direction, the first cover plate 11 and the edges of the middle frame 20 are spaced apart (see FIG1 ). This prevents the first cover plate 11 from protruding from the edges of the middle frame 20, which helps improve the aesthetics of the terminal structure assembly 100. When the first cover plate 11 protrudes from the edges of the middle frame 20, the protruding portion of the first cover plate 11 is more likely to collide with the outside world. Therefore, by providing a spacing between the edges of the first cover plate 11 and the middle frame 20, the service life of the first cover plate 11 is also improved, and collisions with the outside world that affect the stability of the connection between the first cover plate 11 and the middle frame 20 are prevented, thereby improving the structural stability of the terminal structure assembly 100.

[0066] Please refer to Figure 9, which shows a schematic structural diagram of the first cover plate provided in an embodiment of the present application. The first cover plate 11 has a through hole 111, which extends through the first cover plate 11 along a first direction. The through hole 111 is connected to the accommodating groove 21. Part of the lens assembly 30 extends from the opening of the accommodating groove 21 in the first direction and is located within the through hole 111, so that a portion of the lens assembly 30 is located within the accommodating groove 21 of the middle frame 20, and the other portion of the lens assembly 30 is located within the through hole 111 of the first cover plate 11. The accommodating groove 21 and the through hole 111 are both used to accommodate the lens assembly 30. In the first direction, the total thickness of the middle frame 20 and the first cover plate 11 is greater than or equal to the length of the lens assembly 30, which satisfies the need for the middle frame 20 and the first cover plate 11 to accommodate the lens assembly 30.

[0067] On the premise that the terminal structure assembly 100 can accommodate the lens assembly 30, a through hole 111 is provided on the first cover plate 11. The length of the lens assembly 30 and the thickness of the first cover plate 11 partially overlap in the first direction, so that the terminal structure assembly 100 reduces the thickness of the overlapping portion of the lens assembly 30 and the first cover plate 11 in the first direction, and the thickness of the terminal structure assembly 100 in the first direction is reduced. Compared with the case where the first cover plate 11 is not provided with the through hole 111, the lens assembly 30 is only located in the accommodating groove 21 of the middle frame 20. In order to accommodate the lens assembly 30, the thickness of the middle frame 20 in the first direction needs to be greater than or equal to the length of the lens assembly 30. This reduces the total thickness of the middle frame 20 and the first cover plate 11 in the first direction, that is, reduces the thickness of the terminal structure assembly 100 in the first direction, which is conducive to achieving a lighter and thinner terminal structure assembly 100 and improving the portability of the terminal structure assembly 100.

[0068] In some embodiments, there is a spacing distance between the lens assembly 30 and the inner wall of the through hole 111, which provides a larger space for the through hole 111 to accommodate the lens assembly 30, simplifies the installation of the first cover plate 11, and avoids interference between the first cover plate 11 and the lens assembly 30.

[0069] In one embodiment, please refer to Figures 5 and 6. Figure 5 shows a schematic cross-sectional structural diagram of the middle frame 20 and the cover plate assembly 10 provided in the embodiment shown in Figure 3, and Figure 6 shows a cross-sectional view of the middle frame and the cover plate assembly provided in the embodiment shown in Figure 5 at position BB. The area of ​​the through hole 111 is smaller than the area of ​​the opening of the receiving groove 21. The projection of the edge of the through hole 111 in the first direction (such as the X direction in Figure 5) is located within the projection range of the edge of the opening of the receiving groove 21 in the first direction. The first cover plate 11 partially covers the opening of the receiving groove 21 (see Figure 6). The edges of the through hole 111 protrude from the edges of the opening of the receiving groove 21 in a direction perpendicular to the first direction to improve the uniformity of the first cover plate 11 covering the opening of the receiving groove 21.

[0070] For example, referring to FIG6 , the shape of the through hole 111 and the shape of the opening of the receiving groove 21 are both squares, the side length of the through hole 111 is L1, and the side length of the opening of the receiving groove 21 is L2. The through hole 111 and the receiving groove 21 satisfy the relationship: L1<L2, so that the area of ​​the through hole 111 is smaller than the area of ​​the opening of the receiving groove 21.

[0071] By making the area of ​​the through hole 111 smaller than the area of ​​the opening of the receiving groove 21, the structure of the middle frame 20 and the first cover plate 11 is transitioned near the opening of the receiving groove 21, and the size of the through hole 111 is appropriately reduced, which is conducive to improving the structural strength of the first cover plate 11, ensuring that the first cover plate 11 has sufficient impact resistance, that is, ensuring the first cover plate 11's ability to protect the lens assembly 30. Exemplarily, the shape of the through hole 111 and the opening of the receiving groove 21 are both circular, the center of the through hole 111 and the center of the opening of the receiving groove 21 are on the same straight line, the straight line extending along the first direction, and the diameter of the through hole 111 is smaller than the diameter of the opening of the receiving groove 21.

[0072] Referring to Figures 3 and 8, the edge of the second cover plate 12 is connected to the first cover plate 11, the central area of ​​the second cover plate 12 encloses the through hole 111, and the second cover plate 12 completely covers the through hole 111 in the first direction. Because the second cover plate 12 partially corresponds to the through hole 111, the first cover plate 11 is connected to the portion of the second cover plate 12 that does not cover the through hole. The first cover plate 11 can be completely connected to the second cover plate 12, or the first cover plate 11 can be partially connected to the second cover plate 12. For example, the projected area of ​​the second cover plate 12 in the first direction is smaller than the projected area of ​​the first cover plate 11 in the first direction, that is, a portion of the first cover plate 11 is connected to a portion of the second cover plate 12.

[0073] The area of ​​the second cover plate 12 is greater than or equal to the area of ​​the through hole 111, that is, the projection area of ​​the second cover plate 12 in the first direction is greater than or equal to the projection area of ​​the edge of the through hole 111 in the first direction. At the same time, the projection of the edge of the through hole 111 in the first direction is within the projection range of the second cover plate 12 in the first direction.

[0074] The second cover plate 12 is connected to the edge of the first cover plate 11 enclosing the through hole 111. In one embodiment, please refer to Figure 5. The area of ​​the second cover plate 12 is larger than the area of ​​the through hole 111. The second cover plate 12 is connected to the surface of the first cover plate 11 away from the middle frame 20, so that in the first direction (such as the X direction in Figure 5), a part of the second cover plate 12 is opposite to the through hole 111, and another part of the second cover plate 12 is opposite to the first cover plate 11. The first cover plate 11 is connected to and supports the second cover plate 12, which is conducive to lifting the second cover plate 12 The stability of the connection with the first cover plate 11 makes the structure of the cover plate assembly 10 more stable, and the second cover plate 12 is not easy to separate from the first cover plate 11, which ensures the sealing effect of the second cover plate 12 on the through hole 111, so that the sealing inside the accommodating groove 21 is better, avoiding external dust and other substances from entering the lens assembly 30, and ensuring the imaging effect of the lens assembly 30; at the same time, the first cover plate 11 and the second cover plate 12 have stronger impact resistance, and also improve the protection ability of the first cover plate 11 and the second cover plate 12 to the lens assembly 30.

[0075] When the second cover plate 12 closes the through hole 111, the lens assembly 30 is located between the second cover plate 12 and the bottom wall of the accommodating groove 21. The second cover plate 12 and the bottom wall of the accommodating groove 21 respectively apply forces in the first direction toward the lens assembly 30. The second cover plate 12 and the bottom wall of the accommodating groove 21 clamp and fix the lens assembly 30. The lens assembly 30 is clamped between the second cover plate 12 and the bottom wall of the accommodating groove 21, which is conducive to further improving the stability of the position of the lens assembly 30.

[0076] The first cover plate 11 and the second cover plate 12 are located on the same side of the lens assembly 30 in the first direction. The first cover plate 11 and the second cover plate 12 can withstand and absorb external impact forces, thereby protecting the lens assembly 30. When the terminal structure assembly 100 only includes the first cover plate 11, and the first cover plate 11 is provided with a groove that communicates with the accommodating groove 21, a portion of the lens assembly 30 is located within the accommodating groove 21, and another portion of the lens assembly 30 extends from the opening of the accommodating groove 21 in the first direction and is located within the groove of the first cover plate 11, the length of the lens assembly 30 and the thickness of the first cover plate 11 partially overlap in the first direction, which can also reduce the thickness of the terminal structure assembly 100 in the first direction. However, the thickness of the first cover plate 11 is relatively small at the location of the groove, resulting in a lower structural strength of the first cover plate 11 at the location of the groove, making it susceptible to damage when impacted. At the same time, stress concentration occurs at the junction of the sidewall and bottom wall of the groove of the first cover plate 11, which is prone to a notch effect, resulting in poor impact resistance of the first cover plate 11, and thus poor protection of the lens assembly 30 by the first cover plate 11. By making the terminal structure assembly 100 include a first cover plate 11 and a second cover plate 12 connected to each other, the first cover plate 11 is provided with a through hole 111, the second cover plate 12 is connected to the first cover plate 11, and the second cover plate 12 covers the through hole 111, it is beneficial for the length of the lens assembly 30 and the thickness of the first cover plate 11 to partially overlap in the first direction, thereby reducing the thickness of the terminal structure assembly 100 in the first direction, and it is also beneficial for improving the structural strength of the first cover plate 11 and the second cover plate 12, so that the external impact force exerted on the terminal structure assembly 100 is dispersed to the first cover plate 11 and the second cover plate 12, thereby improving the impact resistance of the first cover plate 11 and the second cover plate 12, and thereby ensuring the protection capability of the first cover plate 11 and the second cover plate 12 for the lens assembly 30.

[0077] The present application provides a terminal structure assembly 100, which includes a lens assembly 30, a middle frame 20 and a cover assembly 10. The middle frame 20 has a receiving groove 21, and part of the lens assembly 30 is located in the receiving groove 21. The lens assembly 30 is fixed to the bottom wall of the receiving groove 21, so that the middle frame 20 supports and fixes the lens assembly 30, ensuring the stability of the position of the lens assembly 30 relative to the middle frame 20. The cover plate assembly 10 includes a first cover plate 11 and a second cover plate 12. The middle frame 20, the first cover plate 11, and the second cover plate 12 are sequentially connected in a first direction. At least a portion of the middle frame 20 is connected to at least a portion of the first cover plate 11, and at least a portion of the first cover plate 11 is connected to a portion of the second cover plate 12. This helps to ensure the connection area between the first cover plate 11 and the middle frame 20, and the second cover plate 12 and the first cover plate 11, thereby improving the stability of the connection structure between the middle frame 20 and the cover plate assembly 10. The cover plate assembly 10 and the middle frame 20 have strong impact resistance, thereby ensuring the cover plate assembly 10 and the middle frame 20's ability to protect the lens assembly 30. The cover plate assembly 10 closes the opening of the accommodating groove 21, and the cover plate assembly 10 and the bottom wall of the accommodating groove 21 clamp the lens assembly 30, further achieving the position fixation of the lens assembly 30.

[0078] The first cover plate 11 has a through hole 111, and the second cover plate 12 is connected to the first cover plate 11 and closes the through hole 111, so that the external impact force on the cover plate assembly 10 can be dispersed to the first cover plate 11 and the second cover plate 12, thereby improving the impact resistance of the cover plate assembly 10 and ensuring the protection of the lens assembly 30 by the first cover plate 11 and the second cover plate 12. A portion of the lens assembly 30 extends from the opening of the accommodating groove 21 in the first direction and is located within the through hole 111, so that the length of the lens assembly 30 and the thickness of the first cover plate 11 partially overlap in the first direction. Under the premise that the terminal structure assembly 100 can accommodate the lens assembly 30, the thickness of the terminal structure assembly 100 in the first direction is reduced, which is conducive to achieving a lighter and thinner terminal structure assembly 100 and improving the portability of the terminal structure assembly 100.

[0079] In one possible embodiment, referring to Figures 3, 7, 8 and 9, the first cover plate 11 has an outer surface 112, which is the surface of the first cover plate 11 facing away from the middle frame 20 in a first direction (such as the X direction in Figure 3). The outer surface 112 has a first groove 113, that is, the opening and bottom wall of the first groove 113 are arranged relative to each other in the first direction.

[0080] The first groove 113 is used to accommodate the second cover plate 12. The second cover plate 12 is connected to the bottom wall of the first groove 113, and the bottom wall of the first groove 113 is also used to support the second cover plate 12. For example, the bottom wall of the first groove 113 can simultaneously support and connect the second cover plate 12. Compared to a situation where the bottom wall of the first groove 113 supports the second cover plate 12 while the side walls of the first groove 113 connect to the second cover plate 12, having the bottom wall of the first groove 113 simultaneously support and connect the second cover plate 12 helps simplify the connection process between the second cover plate 12 and the first cover plate 11. At the same time, because the thickness of the first cover plate 11 in the first direction needs to be compressed, the side wall area of ​​the first groove 113 is relatively small. If the second cover plate 12 is connected to the side wall of the first groove 113, the connection area between the second cover plate 12 and the first cover plate 11 is relatively small, which is not conducive to the stability of the connection between the second cover plate 12 and the first cover plate 11. Connecting the second cover plate 12 to the bottom wall of the first groove 113 is conducive to fully utilizing the space of the first cover plate 11 in the direction perpendicular to the first direction, ensuring that the second cover plate 12 and the first cover plate 11 have a larger connection area, and thus ensuring the stability of the connection structure between the second cover plate 12 and the first cover plate 11.

[0081] Referring to Figure 9 , the first groove 113 surrounds the through-hole 111, allowing the second cover plate 12 to seal the through-hole 111 after being connected to the bottom wall of the first groove 113, thereby simplifying the arrangement of the second cover plate 12. When the first groove 113 surrounds the through-hole 111, the sidewalls of the first groove 113 surround the through-hole 111, and a distance is provided between the sidewalls of the first groove 113 and the opening edge of the through-hole 111 in a direction perpendicular to the first direction. This allows the bottom wall of the first groove 113 to have a certain area, ensuring a sufficient connection area between the second cover plate 12 and the bottom wall of the first groove 113. Compared to a case where the sidewalls of the first groove 113 are flush with the inner wall of the through-hole 111, this improves the stability of the connection between the second cover plate 12 and the first cover plate 11.

[0082] The first groove 113 is connected to the through hole 111, that is, the through hole 111 is provided on the bottom wall of the first groove 113, which helps to simplify the arrangement of the first groove 113 and the through hole 111. The second cover plate 12 is fitted and connected to the bottom wall of the first groove 113, and at least a portion of the second cover plate 12 is located within the first groove 113. In the first direction, the thickness of the second cover plate 12 and the depth of the first groove 113 at least partially overlap, that is, the thickness of the second cover plate 12 and the thickness of the first cover plate 11 at least partially overlap in the first direction, reducing the thickness of the cover plate assembly 10 in the first direction, that is, reducing the thickness of the terminal structure assembly 100 in the first direction, which helps to achieve a lighter and thinner terminal structure assembly 100.

[0083] In one embodiment, referring to FIG4 , a distance is provided between the sidewalls of the second cover plate 12 and the sidewalls of the first groove 113 in a direction perpendicular to the first direction. This provides more space for the first groove 113 to accommodate the second cover plate 12, and provides a reserved gap for the setting error of the first groove 113 and the manufacturing error of the second cover plate 12. This prevents the second cover plate 12 from being unable to be installed in the first groove 113, thereby simplifying the installation of the second cover plate 12 in the first groove 113. At the same time, this prevents the sidewalls of the second cover plate 12 from being in too close contact with the sidewalls of the first groove 113, which could cause damage to the first cover plate 11 and the second cover plate 12 by pressing against each other at the contact position when the first cover plate 11 and / or the second cover plate 12 expands due to heat. This provides space for moderate deformation of the first cover plate 11 and the second cover plate 12, thereby improving the service life of the first cover plate 11 and the second cover plate 12.

[0084] In a possible embodiment, please refer to Figures 3, 7, 8, 9 and 10. Figure 10 shows a side view of the first cover plate provided in an embodiment of the present application and a partial enlarged view thereof. A convex portion 114 is provided on the outer surface 112 of the first cover plate 11. The convex portion 114 protrudes from the outer surface 112 along a first direction (such as the X direction in Figure 3). The convex portion 114 surrounds the periphery of the first groove 113, and the convex portion 114 surrounds the first groove 113. When the second cover plate 12 is located in the first groove 113, the convex portion 114 surrounds the second cover plate 12. The surface of the convex portion 114 close to the first groove 113 encloses the second cover plate 12 in a direction perpendicular to the first direction. The convex portion 114 can limit the second cover plate 12 in a direction perpendicular to the first direction, which is beneficial to improving the stability of the position of the second cover plate 12.

[0085] The protrusion 114 and the first cover plate 11 can be an integral structure. The surface of the protrusion 114 near the first groove 113 can be spaced apart from the sidewall of the first groove 113, so that the depth of the first groove 113 is the distance from the bottom wall of the first groove 113 to the outer surface 112 in the first direction. Alternatively, the surface of the protrusion 114 near the first groove 113 constitutes the sidewall of the first groove 113, so that the depth of the first groove 113 is the sum of the distance from the bottom wall of the first groove 113 to the outer surface 112 in the first direction and the distance that the protrusion 114 protrudes from the outer surface 112 in the first direction.

[0086] In one embodiment, the surface of the protrusion 114 on the side closest to the first groove 113 forms the sidewall of the first groove 113, which facilitates increasing the depth of the first groove 113 in the first direction. The first groove 113 is used to accommodate the second cover plate 12, allowing the thickness of the second cover plate 12 in the first direction to be appropriately increased, which facilitates improving the structural strength of the second cover plate 12, enhancing the impact resistance of the second cover plate 12, and thereby improving the protection of the lens assembly 30 by the second cover plate 12. Referring to FIG. 10 , the surface of the protrusion 114 on the side away from the first groove 113 can be a smooth curved surface. The two sides of this curved surface in the first direction are smoothly connected to the surface of the protrusion 114 facing away from the outer surface 112 and the outer surface 112, respectively. The curved surface is recessed toward the side closest to the outer surface 112 to achieve a smooth structural transition between the protrusion 114 and the outer surface 112 of the first cover plate 11, thereby improving the aesthetics and tactile feel of the first cover plate 11.

[0087] In the first direction, the height of the second cover plate 12 relative to the bottom wall of the first groove 113 is the distance in the first direction between the surface of the second cover plate 12 facing away from the lens assembly 30 and the bottom wall of the first groove 113. The height of the protrusion 114 relative to the bottom wall of the first groove 113 is the maximum height of the protrusion 114 protruding from the bottom wall of the first groove 113 in the first direction. When the surface of the protrusion 114 on the side closest to the first groove 113 forms the side wall of the first groove 113, the height of the protrusion 114 relative to the bottom wall of the first groove 113 is the depth of the first groove 113.

[0088] In some embodiments, in the first direction, the height of the second cover plate 12 relative to the bottom wall of the first groove 113 can be less than or equal to the height of the protrusion 114 relative to the bottom wall of the first groove 113, so that the second cover plate 12 is completely accommodated in the first groove 113, which is beneficial for the protrusion 114 to protect the second cover plate 12; in other embodiments, the height of the second cover plate 12 relative to the bottom wall of the first groove 113 can also be greater than the height of the protrusion 114 relative to the bottom wall of the first groove 113, so that part of the second cover plate 12 is accommodated in the first groove 113, and the other part of the second cover plate 12 extends from the opening of the first groove 113 along the first direction, which is beneficial for reducing the height of the protrusion 114 relative to the bottom wall of the first groove 113, that is, reducing the height of the protrusion 114 relative to the outer surface 112 of the first cover plate 11, so that the transition between the protrusion 114 and the outer surface 112 of the first cover plate 11 is smoother.

[0089] In one embodiment, referring to FIG. 5 , in a first direction (e.g., the X direction in FIG. 5 ), the height of the second cover plate 12 relative to the bottom wall of the first groove 113 is H2, and the height of the protrusion 114 relative to the bottom wall of the first groove 113 is H3. The first cover plate 11 and the second cover plate 12 satisfy the relationship: H2 ≤ H3, such that the height of the second cover plate 12 relative to the bottom wall of the first groove 113 is less than or equal to the height of the protrusion 114 relative to the bottom wall of the first groove 113. The protrusion 114 is flush with the second cover plate 12 or protrudes relative to the second cover plate 12 in the first direction. The protrusion 114 completely encloses the second cover plate 12, allowing the protrusion 114 to limit the position of the second cover plate 12, which helps to improve the stability of the position of the second cover plate 12.

[0090] Referring to Figure 3, the second cover plate 12 encloses the through-hole 111, and a portion of the lens assembly 30 is positioned within the through-hole 111, such that the second cover plate 12 and the lens assembly 30 are disposed opposite each other in a first direction and in contact with each other. When the side of the cover plate assembly 10 provided with the second cover plate 12 contacts an object such as the ground, because the protrusion 114 protrudes relative to the second cover plate 12 in the first direction, the protrusion 114 can contact the ground or other object before the second cover plate 12, reducing the impact on the second cover plate 12 and, in turn, the impact on the lens assembly 30 in contact with the second cover plate 12, thereby facilitating protection of the lens assembly 30. For example, the surface of the protrusion 114 adjacent to the first groove 113 forms the sidewall of the first groove 113, allowing the second cover plate 12 to be fully accommodated within the first groove 113. The sidewall of the first groove 113 limits the position of the second cover plate 12, thereby facilitating stability in the position of the second cover plate 12.

[0091] In a possible embodiment, please refer to Figure 5. In the first direction, the bottom wall of the first groove 113 and the outer surface 112 of the first cover plate 11 have a spacing distance H1, and the first cover plate 11 and the second cover plate 12 satisfy the relationship: H1<H2. The spacing distance is less than the height of the second cover plate 12 relative to the bottom wall of the first groove 113, so that the second cover plate 12 protrudes compared with the first cover plate 11 in the first direction, and the depth of the first groove 113 in the first direction can be appropriately reduced to ensure the thickness of the first cover plate 11 at the first groove 113, that is, to ensure the structural strength of the first cover plate 11 at the first groove 113. The first cover plate 11 has strong impact resistance, which is conducive to ensuring the protection ability of the cover plate assembly 10 for the lens assembly 30.

[0092] When the thickness of the first cover plate 11 and the second cover plate 12 in the first direction remains unchanged, if the second cover plate 12 does not protrude compared to the first cover plate 11 in the first direction, the first cover plate 11 needs to be provided with a first groove 113 with a greater depth in the first direction for accommodating the second cover plate 12. The thickness of the first cover plate 11 at the first groove 113 is reduced, thereby reducing the structural strength of the first cover plate 11 at the first groove 113.

[0093] In the first direction, the thickness of the first cover plate 11, the thickness of the second cover plate 12, and the distance between the bottom wall of the first groove 113 and the outer surface 112 of the first cover plate 11 can be set according to actual needs to ensure the structural strength of the first cover plate 11 and the second cover plate 12, and to avoid the step difference between the second cover plate 12 and the first cover plate 11 being too large, which affects the user experience. The step difference between the second cover plate 12 and the first cover plate 11 is the distance in the first direction between the surface of the second cover plate 12 facing away from the first cover plate 11 and the outer surface 112 of the first cover plate 11. When the step difference between the second cover plate 12 and the first cover plate 11 is small, the structural transition between the second cover plate 12 and the first cover plate 11 is smoother, and the convex portion 114 does not need to be provided on the outer surface 112 for transition.

[0094] In one embodiment, please refer to Figure 3, the outer surface 112 of the first cover plate 11 has a protrusion 114, and the surface of the protrusion 114 close to the first groove 113 constitutes the side wall of the first groove 113. In the first direction, the spacing distance between the bottom wall of the first groove 113 and the outer surface 112 of the first cover plate 11 is less than the height of the second cover plate 12 relative to the bottom wall of the first groove 113, and the height of the second cover plate 12 relative to the bottom wall of the first groove 113 is less than the height of the protrusion 114 relative to the bottom wall of the first groove 113. The second cover plate 12 is completely accommodated in the first groove 113, and the surface of the protrusion 114 close to the first groove 113 constitutes the side wall of the first groove 113, which not only realizes the structural transition between the second cover plate 12 and the first cover plate 11 by the protrusion 114, making the surface of the cover plate assembly 10 on the side with the second cover plate 12 smoother, but also utilizes the height of the protrusion 114 protruding from the outer surface 112 in the first direction to limit the second cover plate 12, reducing the opening depth of the first cover plate 11 at the first groove 113, making the thickness of the first cover plate 11 at the first groove 113 larger, and ensuring the structural strength and impact resistance of the first cover plate 11 at the first groove 113. At the same time, the second cover plate 12 protrudes from the outer surface 112 of the first cover plate 11, and the second cover plate 12 is lower than the protrusion 114. When the side of the cover plate assembly 10 provided with the second cover plate 12 contacts the ground or other objects, the protrusion 114 can contact the ground or other objects before the second cover plate 12, thereby reducing the impact on the second cover plate 12 and facilitating the protection of the lens assembly 30.

[0095] In one embodiment, referring to Figures 3 and 5 , a first adhesive member 261 is provided on the bottom wall of the first groove 113. The first adhesive member 261 is located between the first cover plate 11 and the second cover plate 12 and is used to bond the second cover plate 12 to the first cover plate 11. The first adhesive member 261 has a certain thickness in the first direction. In the first direction, the height of the second cover plate 12 relative to the bottom wall of the first groove 113 is the sum of the thickness of the second cover plate 12 and the thickness of the first adhesive member 261.

[0096] In one possible embodiment, referring to FIG. 5 , the thickness of the second cover plate 12 in the first direction is less than that of the first cover plate 11 . Compared to a case where the thickness of the second cover plate 12 is greater than or equal to the thickness of the first cover plate 11 , the second cover plate 12 can be completely located within the first groove 113 . Furthermore, the depth of the first groove 113 in the first direction is relatively small, resulting in a certain thickness of the first cover plate 11 at the first groove 113 . This ensures the structural strength of the first cover plate 11 at the first groove 113 , resulting in a strong impact resistance for the first cover plate 11 , which helps ensure that the cover plate assembly 10 protects the lens assembly 30 . Furthermore, the relatively small thickness of the second cover plate 12 also reduces the height of the second cover plate 12 protruding from the outer surface 112 in the first direction. This not only helps reduce the thickness of the cover plate assembly 10 in the first direction and achieves miniaturization of the terminal structure assembly 100 , but also reduces the step difference between the first cover plate 11 and the second cover plate 12 , resulting in a smoother structural transition between the second cover plate 12 and the first cover plate 11 , which helps ensure that the cover plate assembly 10 has a good appearance and user experience.

[0097] The second cover plate 12 is thinner than the first cover plate 11. In order not to affect the impact resistance of the second cover plate 12, the hardness of the second cover plate 12 is made greater than the hardness of the first cover plate 11, thereby ensuring the structural strength of the second cover plate 12 when the thickness is relatively small. On the premise that the thickness of the cover plate assembly 10 in the first direction is relatively small, the protection ability of the cover plate assembly 10 to the lens assembly 30 is guaranteed.

[0098] In one possible embodiment, please refer to Figures 3, 8, 11, and 12. Figure 12 shows a cross-sectional view of the middle frame at CC and a partially enlarged view thereof, provided in the embodiment shown in Figure 11. In a first direction (such as the X direction in Figures 3 and 12), the surface of the middle frame 20 facing the first cover plate 11 has a second groove 22, with the opening and bottom wall of the second groove 22 being arranged opposite each other in the first direction.

[0099] The second groove 22 is used to accommodate the first cover plate 11. The first cover plate 11 is connected to the bottom wall of the second groove 22, and the bottom wall of the second groove 22 also supports the second cover plate 12. Similar to the design of the first groove 113 and the second cover plate 12, compared to the bottom wall of the second groove 22 supporting the first cover plate 11 and the side walls of the second groove 22 connecting to the first cover plate 11, the bottom wall of the second groove 22 simultaneously supports and connects the first cover plate 11, which helps simplify the connection process between the first cover plate 11 and the middle frame 20. Furthermore, the middle frame 20 is used to support the lens assembly 30 and the cover plate assembly 10, so the middle frame 20 needs to have a certain thickness in the first direction to ensure its structural strength. The depth of the second groove 22 in the middle frame 20 in the first direction is limited, resulting in a smaller sidewall area of ​​the second groove 22. If the first cover plate 11 is connected to the sidewall of the second groove 22, the connection area between the first cover plate 11 and the middle frame 20 is small, which is not conducive to the stability of the connection between the first cover plate 11 and the middle frame 20. Connecting the first cover plate 11 and the bottom wall of the second groove 22 is conducive to fully utilizing the space of the middle frame 20 in the first direction perpendicular to the first direction, ensuring that the first cover plate 11 and the middle frame 20 have a larger connection area, and thus ensuring the stability of the connection structure between the cover plate assembly 10 and the middle frame 20.

[0100] The second groove 22 surrounds the opening of the receiving groove 21, so that after the first cover plate 11 is connected to the bottom wall of the second groove 22, the through hole 111 and the opening of the receiving groove 21 are aligned. When the first cover plate 11 and the middle frame 20 are connected, the sidewalls of the second groove 22 surround the middle frame 20, so that the sidewalls of the second groove 22 enclose the first cover plate 11 in a direction perpendicular to the first direction, thereby ensuring that the middle frame 20 protects the first cover plate 11 in a direction perpendicular to the first direction.

[0101] Referring to Figures 11 and 12 , the second groove 22 is connected to the receiving groove 21, that is, the receiving groove 21 is provided on the bottom wall of the second groove 22, which helps simplify the arrangement of the second groove 22 and the receiving groove 21. The first cover plate 11 is in close contact with the bottom wall of the second groove 22, with at least a portion of the first cover plate 11 located within the second groove 22. In a first direction, the thickness of the first cover plate 11 and the depth of the second groove 22 at least partially overlap, that is, the thickness of the first cover plate 11 and the thickness of the middle frame 20 at least partially overlap in the first direction, reducing the thickness of the terminal structure assembly 100 in the first direction and facilitating a thinner and lighter terminal structure assembly 100.

[0102] In one embodiment, referring to FIG3 , a distance is provided between the sidewalls of the first cover plate 11 and the sidewalls of the second groove 22 in a direction perpendicular to the first direction. This provides more space for the second groove 22 to accommodate the first cover plate 11, and provides a reserved gap for installation errors of the second groove 22 and manufacturing errors of the first cover plate 11. This prevents the first cover plate 11 from being unable to be installed in the second groove 22, thereby simplifying the installation of the first cover plate 11 in the second groove 22. Furthermore, this prevents the sidewalls of the first cover plate 11 and the sidewalls of the second groove 22 from being too close to each other, which could cause damage to the first cover plate 11 and the middle frame 20 by pressing against each other at the contact position when the first cover plate 11 and / or the middle frame 20 expand due to heat. This provides space for moderate deformation of the first cover plate 11 and the middle frame 20, thereby improving the service life of the first cover plate 11 and the middle frame 20.

[0103] In some embodiments, in the first direction, the height of the first cover plate 11 relative to the bottom wall of the second groove 22 can be less than or equal to the depth of the second groove 22, so that the first cover plate 11 is completely accommodated in the second groove 22, which is beneficial for the middle frame 20 to protect the first cover plate 11; in other embodiments, the height of the first cover plate 11 relative to the bottom wall of the second groove 22 can also be greater than the depth of the second groove 22, so that part of the first cover plate 11 is accommodated in the second groove 22, and the other part of the first cover plate 11 extends from the opening of the second groove 22 along the first direction, which is beneficial for reducing the depth of the second groove 22, so that the middle frame 20 has a certain thickness, thereby ensuring the structural strength of the middle frame 20.

[0104] In one embodiment, referring to FIG3 , a second adhesive member 262 is provided on the bottom wall of the second groove 22. The second adhesive member 262 is located between the middle frame 20 and the first cover plate 11 and is used to bond the first cover plate 11 to the middle frame 20. The second adhesive member 262 has a certain thickness in the first direction. In the first direction, the height of the first cover plate 11 relative to the bottom wall of the second groove 22 is the sum of the thickness of the first cover plate 11 and the thickness of the second adhesive member 262.

[0105] The design concept of the second groove 22 is similar to that of the first groove 113. Both can improve the stability of the connection between the various components in the terminal structure assembly 100, and make the thickness of the two connected components in the first direction at least partially overlap, thereby reducing the thickness of the terminal structure assembly 100 in the first direction, thereby achieving the terminal structure assembly 100 being lightweight and thin.

[0106] In one possible embodiment, please refer to Figure 3, the projection of the second cover plate 12 in the first direction partially overlaps with the projection of the middle frame 20 in the first direction, and the middle frame 20 can indirectly support the second cover plate 12, so that the middle frame 20 and the first cover plate 11 are both used to support the second cover plate 12, which is beneficial to improving the stability of the position of the second cover plate 12.

[0107] In one possible embodiment, please refer to Figures 11 and 12, a mating portion 24 is provided on the surface of the middle frame 20 facing the first cover plate 11, and a mating structure corresponding to the mating portion 24 is provided on the surface of the first cover plate 11 facing the middle frame 20. The mating structure on the first cover plate 11 and the mating portion 24 on the middle frame 20 are mated and connected, further improving the stability of the connection between the first cover plate 11 and the middle frame 20.

[0108] The mating portion 24 is located outside the receiving groove 21 and is disposed near the receiving groove 21, placing the mating portion 24 near the lens assembly 30. This helps to increase the stability of the connection between the first cover plate 11 and the middle frame 20 near the lens assembly 30. When the terminal structure assembly 100 is subjected to an external impact, the connection structure between the first cover plate 11 and the middle frame 20 near the lens assembly 30 is not easily damaged, and the cover plate assembly 10 and the middle frame 20 can maintain their enclosure around the lens assembly 30, thereby enhancing the protective capability of the cover plate assembly 10 and the middle frame 20 for the lens assembly 30. The number of mating portions 24 can be at least two, and at least two mating portions 24 are evenly disposed around the receiving groove 21.

[0109] In one possible embodiment, referring to Figures 3 and 8 , after the second cover plate 12 closes the through hole 111, the lens assembly 30 is positioned between the second cover plate 12 and the bottom wall of the receiving groove 21. The second cover plate 12 and the bottom wall of the receiving groove 21 respectively apply forces in a first direction (such as the X direction in Figure 3 ) toward each other to the lens assembly 30, and the second cover plate 12 and the bottom wall of the receiving groove 21 clamp and secure the lens assembly 30. The terminal structure assembly 100 further includes a buffer 240, which is positioned between the lens assembly 30 and the second cover plate 12, such that the buffer 240 is also positioned between the second cover plate 12 and the bottom wall of the receiving groove 21, and the second cover plate 12 and the bottom wall of the receiving groove 21 also clamp the buffer 240.

[0110] The buffer 240 has a certain thickness in the first direction, so that the lens assembly 30 and the second cover plate 12 are spaced apart. The buffer 240 is elastic and can be deformed when subjected to force, so that the spacing distance between the lens assembly 30 and the second cover plate 12 can be adjusted by the degree of deformation of the buffer 240, so that the second cover plate 12 and the bottom wall of the accommodating groove 21 maintain the clamping and fixing of the lens assembly 30, which is beneficial to improving the stability of the position of the lens assembly 30 relative to the middle frame 20.

[0111] In one embodiment, the side of the lens assembly 30 close to the bottom wall of the accommodating groove 21 is the light-incoming side of the lens assembly 30, and the side of the lens assembly 30 close to the cover assembly 10 is the light-emitting side of the lens assembly 30. The lens assembly 30 also includes a sensor chip, which is located on the light-emitting side of the lens assembly 30, that is, the side of the lens assembly 30 close to the cover assembly 10. By disposing a buffer member 240 between the second cover plate 12 and the lens assembly 30, the buffer member 240 can adjust the pressure applied by the second cover plate 12 to the sensor chip of the lens assembly 30 through deformation, thereby preventing the second cover plate 12 from applying excessive pressure on the sensor chip of the lens assembly 30, which could damage the sensor chip.

[0112] The present application also provides a terminal device 200, as shown in Figures 13, 14, and 15. Figure 13 shows a schematic structural diagram of the terminal device 200 provided in an embodiment of the present application, Figure 14 shows a cross-sectional view of the terminal device 200 at position DD provided in the embodiment shown in Figure 13, and Figure 15 shows an enlarged view of the terminal device 200 at position c provided in the embodiment shown in Figure 14. The terminal device 200 includes the terminal structure assembly 100 and a screen 210 as described in any of the above embodiments. The screen 210 is located on one side of the terminal structure assembly 100 in a first direction (such as the X direction in Figures 14 and 15). The screen 210 is connected to the middle frame 20 of the terminal structure assembly 100, and the screen 210 is located on a side of the middle frame 20 away from the cover assembly 10, so that the middle frame 20 is located between the screen 210 and the cover assembly 10.

[0113] At least a portion of the screen 210 is connected to at least a portion of the middle frame 20 in the first direction. The projection area of ​​the screen 210 in the first direction is less than or equal to the projection area of ​​the middle frame 20 in the first direction. At the same time, the projection of the screen 210 in the first direction is within the projection range of the middle frame 20 in the first direction, or the projection of the screen 210 in the first direction completely overlaps with the projection of the middle frame 20 in the first direction. The size relationship between the projection of the screen 210 in the first direction and the projection of the cover assembly 10 in the first direction can be set according to actual needs and is not limited in this application.

[0114] In one embodiment, referring to FIG. 14 , the cover assembly 10, the middle frame 20, and the screen 210 are sequentially connected in a first direction. The projection areas of the cover assembly 10 and the screen 210 in the first direction are both smaller than the projection areas of the middle frame 20 in the first direction. The projections of the cover assembly 10 and the screen 210 in the first direction are both within the projection range of the middle frame 20 in the first direction. Furthermore, in a direction perpendicular to the first direction, the cover assembly 10 and the screen 210 are spaced apart from the four edges of the middle frame 20. This prevents the cover assembly 10 and the screen 210 from protruding beyond the four edges of the middle frame 20, thereby enhancing the aesthetics of the terminal device 200. Furthermore, this prevents the cover assembly 10 and the screen 210 from easily colliding with the outside world, ensuring that the middle frame 20 protects the cover assembly 10 and the screen 210.

[0115] In one embodiment, referring to Figures 12 and 15 , the surface of the middle frame 20 facing away from the first cover plate 11 includes a third groove 14. The opening and bottom wall of the third groove 14 are arranged relative to each other in a first direction (the X direction in Figures 12 and 15 ). The lens hole 23 extends through the bottom wall of the accommodating groove 21 and the bottom wall of the third groove 14, thereby sequentially connecting the accommodating groove 21, the lens hole 23, and the third groove 14. The third groove 14 is used to accommodate the screen 210. The screen 210 is connected to the bottom wall of the third groove 14 to ensure a large connection area between the screen 210 and the middle frame 20, thereby ensuring a stable connection between the screen 210 and the middle frame 20. The third groove 14 surrounds the lens hole 23, so that after the screen 210 is connected to the bottom wall of the third groove 14, the screen 210 can close the lens hole 23, which is conducive to simplifying the setting method of the screen 210; at the same time, when the screen 210 is connected to the bottom wall of the third groove 14, the side wall of the third groove 14 encloses the screen 210, and limits the screen 210 in a direction perpendicular to the first direction, which is conducive to improving the stability of the position of the screen 210.

[0116] The screen 210 is fitted and connected to the bottom wall of the third groove 14, and at least a portion of the screen 210 is located in the third groove 14. In the first direction, the thickness of the screen 210 and the depth of the third groove 14 at least partially overlap, that is, the thickness of the screen 210 and the thickness of the middle frame 20 at least partially overlap in the first direction, which reduces the total thickness of the screen 210 and the middle frame 20 in the first direction, that is, reduces the thickness of the terminal device 200 in the first direction, which is conducive to achieving a lightweight and thin terminal device 200.

[0117] In one possible embodiment, referring to Figures 11, 12, and 15, the bottom wall of the receiving groove 21 has a lens hole 23. The lens hole 23 extends through the bottom wall of the receiving groove 21 in a first direction, and the lens hole 23 is in communication with the receiving groove 21. A portion of the lens assembly 30 is positioned within the lens hole 23, such that a portion of the lens assembly 30 is positioned within the receiving groove 21 of the middle frame 20, and another portion of the lens assembly 30 is positioned within the lens hole 23 at the bottom wall of the receiving groove 21. Both the receiving groove 21 and the lens hole 23 are configured to accommodate the lens assembly 30.

[0118] The screen 210 blocks the lens aperture 23, meaning that the screen 210 completely covers the lens aperture 23 in the first direction. The area of ​​the screen 210 is greater than or equal to the area of ​​the lens aperture 23. Specifically, the projected area of ​​the screen 210 in the first direction is greater than or equal to the projected area of ​​the edge of the lens aperture 23 in the first direction. Furthermore, the projection of the edge of the lens aperture 23 in the first direction is within the projection range of the screen 210 in the first direction. By blocking the lens aperture 23, the cover assembly 10, the middle frame 20, and the screen 210 are sealed against the lens assembly 30. This provides a strong seal within the receiving groove 21, preventing external dust and other substances from entering the lens assembly 30 and ensuring the imaging quality of the lens assembly 30.

[0119] The screen 210 has a light-transmitting area, which is arranged opposite the lens hole 23 in a first direction, so that external light can pass through the light-transmitting area and lens hole 23 into the lens assembly 30, thereby realizing imaging by the lens assembly 30. In one embodiment, the side of the lens assembly 30 near the bottom wall of the accommodating groove 21 is the light-incoming side of the lens assembly 30, and the side of the lens assembly 30 near the cover assembly 10 is the light-outgoing side of the lens assembly 30. The area of ​​the lens hole 23 and the light-transmitting area are both larger than the area of ​​the light-incoming hole of the lens assembly 30, preventing the middle frame 20 and the screen 210 from blocking the light entering the lens assembly 30, allowing external light to enter the lens assembly 30 smoothly.

[0120] Please refer to Figures 15, 16, and 17. Figure 16 shows a cross-sectional perspective view of the terminal device 200 provided in the embodiment shown in Figure 13 at position DD and a partially enlarged view thereof. Figure 17 shows an exploded view of the terminal device 200 provided in the embodiment shown in Figure 13. In the first direction, the surface of the screen 210 facing the middle frame 20 has an escape groove 211. The opening and bottom wall of the escape groove 211 are arranged opposite each other in the first direction. The escape groove 211 is connected to the lens aperture 23. The lens assembly 30 protrudes from the lens aperture 23, so that a portion of the lens assembly 30 extends from the lens aperture 23 in the first direction and is located within the escape groove 211.

[0121] A portion of the lens assembly 30 is located within the receiving groove 21 of the middle frame 20, and another portion of the lens assembly 30 is located within the lens hole 23 and the avoidance groove 211. The receiving groove 21, the lens hole 23, and the avoidance groove 211 are all used to accommodate the lens assembly 30. In one embodiment, the lens assembly 30 is partially located within the through hole 111 of the first cover plate 11, partially located within the receiving groove 21, partially located within the lens hole 23, and partially located within the avoidance groove 211. The through hole 111, the receiving groove 21, the lens hole 23, and the avoidance groove 211 are all used to accommodate the lens assembly 30.

[0122] On the premise that the terminal device 200 can accommodate the lens assembly 30, an avoidance groove 211 is set on the screen 210. The length of the lens assembly 30 and the thickness of the avoidance groove 211 partially overlap in the first direction, so that the thickness of the overlapping part of the lens assembly 30 and the screen 210 of the terminal device 200 is reduced in the first direction. The thickness of the terminal device 200 in the first direction is reduced, which is conducive to realizing the lightweight and thinness of the terminal device 200 and improving the portability of the terminal device 200.

[0123] In one embodiment, please refer to Figure 15, the bottom wall of the avoidance groove 211 and the lens assembly 30 are spaced apart in the first direction, which provides a larger space for the avoidance groove 211 to accommodate the lens assembly 30, which is beneficial to simplifying the setting method of the screen 210; at the same time, it avoids the bottom wall of the avoidance groove 211 from contacting the lens assembly 30, resulting in friction between the bottom wall of the avoidance groove 211 and the lens assembly 30, which is beneficial to the protection of the lens assembly 30 by the screen 210.

[0124] In one possible embodiment, please refer to Figure 13, the middle frame 20 includes a first middle frame 26 and a second middle frame 27, and the first middle frame 26 and the second middle frame 27 are rotatably connected. The terminal structure assembly 100 also includes a connecting member 40, and the connecting member 40 is arranged between the first middle frame 26 and the second middle frame 27, so that the first middle frame 26 and the second middle frame 27 rotate with the connecting member 40 as the axis of rotation.

[0125] The first cover plate 11 includes a main cover plate 115 and a secondary cover plate 116. The main cover plate 115 is connected to the first middle frame 26, and the secondary cover plate 116 is connected to the second middle frame 27. Referring to Figures 13 and 18, Figure 18 shows a schematic diagram of the folded structure of the terminal device 200 provided by the embodiment shown in Figure 13. The middle frame 20 includes an expanded state, a folded state, and an intermediate state between the expanded and folded states. The first middle frame 26 and the second middle frame can rotate relative to each other about the connecting member 40 as a rotation axis, enabling the middle frame 20 to switch between the expanded state and the folded state.

[0126] When the middle frame 20 is in the unfolded state (see Figure 13 ), the angle between the first middle frame 26 and the second middle frame 27 is approximately 180°. A connector 40 is provided between the first middle frame 26 and the second middle frame 27 to space the first middle frame 26 and the second middle frame 27 apart, and the primary cover 115 and the secondary cover 116 are spaced apart. When the middle frame 20 is in the folded state (see Figure 18 ), the angle between the first middle frame 26 and the second middle frame 27 is approximately 0°.

[0127] The embodiments shown in Figures 14 and 15 disclose cross-sectional schematic diagrams of the lens assembly 30 of the middle frame 20 in the unfolded state, and the embodiments shown in Figures 19 and 20 disclose cross-sectional schematic diagrams of the lens assembly 30 of the middle frame 20 in the folded state. The unfolded state and folded state of the middle frame 20 are described in detail below in conjunction with Figures 14, 15, 19 and 20.

[0128] Referring to Figures 13, 14, and 15, the first middle frame 26 has a receiving groove 21, allowing the lens assembly 30 to be positioned on the first middle frame 26. The main cover plate 115 and the first middle frame 26 are connected in a first direction. The main cover plate 115 has a through hole 111, and the second cover plate 12 closes the through hole 111, connecting the second cover plate 12 and the main cover plate 115. In other words, the first middle frame 26, the main cover plate 115, and the second cover plate 12 are sequentially connected in the first direction. Referring to Figure 15, the outer surface of the main cover plate 115 has a protrusion 114. The protrusion 114 surrounds the periphery of the first groove and protrudes from the outer surface of the main cover plate 115.

[0129] Please refer to Figures 13, 19, and 20. Figure 19 shows a cross-sectional view of the terminal device 200 provided in the embodiment shown in Figure 18 at position FF and a partially enlarged view thereof. Figure 20 shows a cross-sectional perspective view of the terminal device 200 provided in the embodiment shown in Figure 18 at position FF and a partially enlarged view thereof. The secondary cover 116 has a receiving groove 117. The receiving groove 117 is recessed relative to the outer surface of the secondary cover 116. When the middle frame 20 is in the folded state, the angle between the first middle frame 26 and the second middle frame 27 is approximately zero. The protrusion 114 is accommodated in the receiving groove 117. This helps to reduce the thickness of the terminal structure assembly 100 in the first direction when the middle frame 20 is in the folded state, thereby achieving miniaturization of the terminal structure assembly 100.

[0130] In one embodiment, referring to FIG. 19 , when the middle frame 20 is in a folded state, the protrusion 114 is accommodated in the receiving groove 117. The depth of the receiving groove 117 can be reasonably set so that the surface of the protrusion 114 facing away from the first middle frame 26 can be in contact with the bottom wall of the receiving groove 117. This prevents the depth of the receiving groove 117 from being too large and affecting the thickness of the secondary cover 116, thereby facilitating the structural strength of the secondary cover 116. The surrounding side surfaces of the protrusion 114 and the side walls of the receiving groove 117 are spaced apart so that the area of ​​the receiving groove 117 is larger than that of the protrusion 114, and the side walls of the receiving groove 117 can enclose the protrusion 114, providing more space for the receiving groove 117 to accommodate the protrusion 114, thereby facilitating the smooth accommodation of the protrusion 114 in the receiving groove 117 when the middle frame 20 is folded.

[0131] The terminal device 200 includes a terminal structure component 100 and a screen 210. The screen 210 is located on the side of the middle frame 20 away from the cover assembly 10. In one embodiment, please refer to Figure 19. The side of the first middle frame 26 away from the main cover 115 can have a screen 210, and the side of the second middle frame 27 away from the secondary cover 116 can also have a screen 210. The screen 210 connected to the first middle frame 26 and the second middle frame 27 is an integrated structure, that is, a flexible display screen.

[0132] When the middle frame 20 is in the unfolded state, please refer to Figures 13, 14 and 15. The screen 210 is fully unfolded, and the part where the screen 210 is connected to the first middle frame 26 and the part where the screen 210 is connected to the second middle frame 27 are approximately located on the same plane, and the plane is perpendicular to the first direction (the X direction as shown in Figures 14 and 15). When the middle frame 20 is in the folded state, please refer to Figures 18, 19 and 20. The first middle frame 26 rotates relative to the second middle frame 27 with the connecting member 40 as the rotating axis. The part of the screen 210 connected to the first middle frame 26 rotates with the rotation of the first middle frame 26. The part of the screen 210 connected to the first middle frame 26 and the part of the screen 210 connected to the second middle frame 27 are close to each other, so that the screen 210 is bent. Please refer to Figure 18. The bending center of the screen 210 is bent, and at this time the screen 210 is located on the outside of the terminal device 200, which is conducive to the design of the external folding screen of the terminal device 200, reducing the setting range of the screen 210, and realizing the miniaturization of the terminal device 200.

[0133] In one possible embodiment, please refer to Figures 21 and 22. Figure 21 shows a schematic structural diagram of a terminal device 200 provided in an embodiment of the present application without a main cover plate 115, and Figure 22 shows a cross-sectional view of the terminal device 200 at EE and a partial enlarged view thereof provided in the embodiment shown in Figure 13. The terminal device 200 also includes a speaker module 220, which is fixedly connected to the middle frame 20. The lens assembly 30 has a bracket 31, which is located on the periphery of the lens assembly 30 and is used to support and protect the lens in the lens assembly 30. The speaker module 220 has a first abutting portion 221, and the middle frame 20 has a second abutting portion 25. In the first direction (such as the X direction in Figure 22), the bracket 31 is located between the first abutting portion 221 and the second abutting portion 25. The first abutting portion 221 abuts against the bracket 31 along the first direction, and the second abutting portion 25 abuts against the bracket 31 in the opposite direction of the first direction, so that the first abutting portion 221 and the second abutting portion 25 respectively apply opposite forces along the first direction to the bracket 31. The middle frame 20 and the speaker module 220 clamp and fix the lens assembly 30, which is conducive to further improving the stability of the position of the lens assembly 30.

[0134] In one possible embodiment, please refer to Figures 14, 15, 16, 17, and 22. Figure 22 shows a schematic structural diagram of a positioning member 230 provided in an embodiment of the present application. The terminal device 200 also includes a positioning member 230, which is located in the receiving groove 21. The positioning member 230 is connected to the bottom wall of the receiving groove 21, and at least a portion of the positioning member 230 is located between the lens assembly 30 and the bottom wall of the receiving groove 21. The lens assembly 30 is fixed to the positioning member 230.

[0135] The positioning member 230 has a positioning hole 233, which is connected to the lens hole 23. The lens assembly 30 passes through the positioning hole 233 and the lens hole 23 in sequence in a first direction (such as the X direction in Figures 14 and 15), so that part of the lens assembly 30 is located in the positioning hole 233. The center of the positioning hole 233 and the center of the lens hole 23 are located on the same straight line, and the straight line extends along the first direction. When assembling the terminal device 200, the center of the positioning hole 233 and the center of the lens hole 23 are first aligned, and then the optical axis of the lens assembly 30 is passed through the center of the positioning hole 233. This can achieve the positioning of the position setting of the lens assembly 30, thereby improving the accuracy of the assembly of the lens assembly 30.

[0136] In one embodiment, referring to FIG. 23 , the positioning member 230 includes a first portion 231 and a second portion 232 connected to each other. The first portion 231 and the second portion 232 can be an integral structure or two connected components, which is not limited in this application. The first portion 231 is connected to the bottom wall of the receiving groove 21 and has a positioning hole 233. The second portion 232 extends from the first portion 231 toward the opening of the receiving groove 21. The second portion 232 encloses the lens assembly 30. The second portion 232 and the lens assembly 30 are spaced apart to simplify the installation of the lens assembly 30 relative to the positioning member 230 and to protect the lens assembly 30. The second portion 232 does not extend from the opening so that the positioning member 230 is fully accommodated in the receiving groove 21, preventing the positioning member 230 from interfering with the arrangement of other components. Exemplarily, the second portion 232 is spaced apart from the opening of the receiving groove 21.

[0137] In one embodiment, referring to FIG. 15 , the terminal device 200 further includes a third adhesive member 263 and a sealing member 250, both of which are located within the receiving groove 21. The third adhesive member 263 is located between the first portion 231 and the bottom wall of the receiving groove 21, and is used to bond the positioning member 230 to the middle frame 20. The sealing member 250 is located between the first portion 231 and the lens assembly 30, and the lens assembly 30 and the positioning member 230 sandwich the sealing member 250. The sealing member 250 is elastic, so that the sealing member 250 and the buffer member 240 can adjust the amount of pressure applied to the lens assembly 30 by the cover assembly 10 and the middle frame 20 through deformation, thereby preventing damage to the lens assembly 30.
