Description

Technical Field

[0001] This application relates to the field of electronic technologies, and particularly to a terminal structure component and a terminal device. Background Art

[0002] With the rapid development of terminal devices equipped with cameras, requirements are put forward for both the imaging quality of the cameras and the portability of the terminal devices. To improve the imaging quality of the cameras, the optical system of the cameras usually needs to have a relatively large optical length, resulting in an increase in the total length of the cameras. To improve the portability of the terminal devices, it is usually necessary to compress the thickness of the terminal devices. When the camera is installed on the terminal device, the length direction of the camera is the same as the thickness direction of the terminal device. It is difficult for a terminal device with a small thickness to accommodate a camera with a large total length. A terminal device equipped with a camera with good imaging quality has a large thickness, reducing its portability. A trade-off needs to be made between the portability of the terminal device and the imaging quality of the camera. Summary of the Invention

[0003] This application provides a terminal structure component and a terminal device. By providing a through hole at the first cover plate, and part of the lens assembly is located in the through hole, so that the lens assembly and the cover plate assembly partially overlap in the thickness direction, reducing the overall thickness of the lens assembly and the cover plate assembly, and realizing the thin and light of the terminal device on the premise of keeping the length of the lens assembly unchanged.

[0004] In a first aspect, this application provides a terminal structure component, including: a lens assembly, the optical axis direction of the lens assembly being the 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 part of the second cover plate are sequentially connected in the first direction, the first cover plate has a through hole, the through hole is communicated with 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.

[0005] The terminal structure component provided by the present application includes a lens component, a middle frame, and a cover plate component. The middle frame has a receiving groove, and a part of the lens component is located in the receiving groove. The lens component is fixed to the bottom wall of the receiving groove, so that the middle frame supports and fixes the lens component, ensuring the stability of the position of the lens component relative to the middle frame. The cover plate component includes a first cover plate and a second cover plate. The middle frame, the first cover plate, and the second cover plate are sequentially connected in a first direction. At least a part of the middle frame is connected to at least a part of the first cover plate, and at least a part of the first cover plate is connected to a part of the second cover plate, which is beneficial to ensuring the connection area between the first cover plate and the middle frame, and between 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 component. The cover plate component and the middle frame have strong impact resistance, thus ensuring the protection ability of the cover plate component and the middle frame to the lens component. The cover plate component closes the opening of the receiving groove, and the cover plate component and the bottom wall of the receiving groove clamp the lens component, further realizing the position fixation of the lens component.

[0006] 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, ensuring the protection ability of the first cover plate and the second cover plate to the lens component. At the same time, the connection between the first cover plate and the second cover plate enables the external impact force received by the cover plate component to be dispersed to the first cover plate and the second cover plate, improving the impact resistance of the cover plate component. A part of the lens component extends out of the opening of the receiving groove in the first direction and is located in the through hole, so that the length of the lens component and the thickness of the first cover plate partially overlap in the first direction. On the premise of meeting the accommodation of the lens component by the terminal structure component, the thickness of the terminal structure component in the first direction is reduced, which is beneficial to realizing the thin and light of the terminal structure component and improving the portability of the terminal structure component.

[0007] In a possible implementation manner, 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, the first groove surrounds the through hole, and the first groove is communicated 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 making the outer surface of the first cover plate have a first groove to accommodate the second cover plate, the thickness of the second cover plate and the depth of the first groove at least partially overlap in the first direction, 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, reducing the thickness of the cover plate component in the first direction, that is, reducing the thickness of the terminal structure component in the first direction, which is beneficial to realizing the thin and light of the terminal structure component.

[0008] In a possible implementation, the outer surface has a convex portion, and the convex portion surrounds the periphery of the first groove. By providing a convex portion on the outer surface of the first cover plate, with the convex portion surrounding the periphery of the first groove, the convex portion can limit the position of the second cover plate in a direction perpendicular to the first direction, which is beneficial to improving the stability of the position of the second cover plate.

[0009] In a possible implementation, 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 convex portion relative to the bottom wall of the first groove. By making the height of the second cover plate relative to the bottom wall of the first groove less than or equal to the height of the convex portion relative to the bottom wall of the first groove in the first direction, the second cover plate is completely accommodated in the first groove, and the side wall of the first groove has a better limiting effect on the second cover plate, which is beneficial to improving the stability of the position of the second cover plate.

[0010] In a possible implementation, in the first direction, the spacing 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 making the spacing distance between the bottom wall of the first groove and the outer surface 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 from the outer surface of the first cover plate in the first direction, which can appropriately reduce the depth of the first groove in the first direction, so that the first cover plate has a certain thickness at the first groove, ensuring the structural strength of the first cover plate at the first groove, and the first cover plate has a strong impact resistance, which is beneficial to ensuring the protection ability of the cover plate assembly for the lens assembly.

[0011] In a possible implementation, in the first direction, the thickness of the second cover plate is less than the thickness of the first cover plate, and the hardness of the second cover plate is greater than the hardness of the first cover plate. By making the thickness of the second cover plate less than the thickness of the first cover plate and the hardness of the second cover plate greater than the hardness of the first cover plate, the thickness of the second cover plate is smaller, which is convenient for the first groove to accommodate and limit the second cover plate; at the same time, the second cover plate has a certain structural strength with a smaller thickness, ensuring the protection ability of the cover plate assembly for the lens assembly on the premise of reducing the thickness of the cover plate assembly in the first direction.

[0012] In a possible implementation, on 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 receiving groove, the second groove communicates with the receiving groove, the second groove is used to receive the first cover plate, and the first cover plate is connected to the bottom wall of the second groove. By making the surface of the middle frame facing the first cover plate have a second groove, the second groove surrounds the opening of the receiving groove, and the second groove receives 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, reducing the thickness of the terminal structure assembly in the first direction, which is beneficial to realizing the thin and light of the terminal structure assembly.

[0013] In a possible implementation, the projection of the second cover plate in the first direction and the projection of the middle frame in the first direction partially overlap. By making the projection of the second cover plate in the first direction and the projection of the middle frame in the first direction partially overlap, the middle frame can indirectly support the second cover plate in the first direction, and both the middle frame and the first cover plate are used to support the second cover plate, which is beneficial to improving the stability of the position of the second cover plate.

[0014] In a second aspect, the present application further provides a terminal device, including the terminal structure assembly according to any one of the above first aspect embodiments and a screen, at least a part of the screen and at least a part of the middle frame are connected in the first direction, and the screen is located on the side of the middle frame away from the cover plate assembly. The beneficial effects corresponding to this embodiment and the above embodiments are similar, and will not be repeated in this embodiment.

[0015] In a possible implementation, the bottom wall of the receiving groove has a lens hole, the screen closes the lens hole, on the first direction, the surface of the screen facing the middle frame has an avoidance groove, the avoidance groove communicates with the lens hole, the lens assembly protrudes from the lens hole, and part of the lens assembly is located in the avoidance groove. By making the bottom wall of the receiving groove have a lens hole, the surface of the screen facing the middle frame have an avoidance groove, the avoidance groove communicates with the lens hole, the lens assembly protrudes from the lens hole, and part of the lens assembly is located in the avoidance groove, on the premise of meeting the accommodation of the lens assembly by the terminal device, the length of the lens assembly and the thickness of the avoidance groove at least partially overlap in the first direction, the thickness of the overlapping part of the lens assembly and the screen in the first direction of the terminal device is reduced, and the thickness of the terminal device in the first direction is reduced, which is beneficial to realizing the thin and light of the terminal device and improving the portability of the terminal device.

[0016] In a possible implementation manner, 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, and the middle frame has a second abutting portion. 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 along 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, the middle frame has a second abutting portion, and the first abutting portion and the second abutting portion respectively apply forces towards each other 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 position of the lens assembly.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0038] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application.

Additionally, in this text, the character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0040] Depending on the context, the word "if" as used herein can be interpreted as "when...", "while...", "in response to determining", or "in response to detecting". Similarly, depending on the context, the phrase "if determined" or "if detected (stated condition or event)" can be interpreted as "when determined", "in response to determining", "when detecting (stated condition or event)", or "in response to detecting (stated condition or event)".

[0041] It should be understood that the "first", "second", etc. used in this application are only 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.

It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application.

[0043] In the description of this application, it should be noted that due to manufacturing errors or assembly errors, there may be some angular deviations in a design that should be perpendicular or parallel. For example, a deviation within 15 degrees also belongs to the perpendicular or parallel described in this embodiment.

[0047] With the rapid development of terminal devices equipped with cameras, requirements are put forward for both the imaging quality of the cameras and the portability of the terminal devices.

[0048] In order to improve the imaging quality of the camera and meet a better photographing experience, it is required that the optical system of the camera has higher resolution and imaging quality. Usually, it is necessary to increase the number of lenses in the optical system or make the lenses in the optical system have a larger moving range on the optical axis. These both increase the total optical length of the optical system, and ultimately lead to an increase in the total length of the camera.

[0049] In order to improve the portability of the terminal device and meet a better usage experience, it is usually necessary to compress the thickness of the terminal device. When the camera is installed on the terminal device, the extending direction of the optical axis of the optical system of the camera is the same as the thickness direction of the terminal device, making the length direction of the camera the same as the thickness direction of the terminal device. It is difficult for a terminal device with a smaller thickness to accommodate a camera with a larger total length. The minimum thickness of the terminal device is limited by the total length of the camera, resulting in a larger thickness for the terminal device equipped with a camera with better imaging quality, reducing its portability. It is necessary to make a trade-off between the portability of the terminal device and the imaging quality of the camera.

[0050] At the same time, in order to mount and protect the camera, it is also necessary to set up corresponding fixing structures to support and connect the camera, and it is necessary to set up a housing with a certain thickness to cover the camera to avoid damage to the camera when it is subjected to external impact forces, achieving the protection effect for the camera. The setting of the fixing structure and the housing further increases the thickness of the terminal device at the camera setting position, which is not conducive to meeting the requirement of the terminal device being thin and light.

[0051] The present application provides a terminal structure assembly 100. Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 shows a schematic structural diagram of the terminal structure assembly 100 provided by an embodiment of the present application, Figure 2 shows Figure 1 a cross-sectional view of the terminal structure assembly 100 provided by the shown embodiment at A-A.Figure 3 shows Figure 2 An enlarged view of the terminal structure component 100 provided by the illustrated embodiment at a. The terminal structure component 100 includes a lens component 30, a middle frame 20, and a cover plate component 10. The middle frame 20 has a receiving groove 21, and a part of the lens component 30 is located in the receiving groove 21. The middle frame 20 supports and connects the lens component 30 to ensure the stability of the position of the lens component 30 relative to the middle frame 20, and realizes the fixation and protection of the lens component 30 by the middle frame 20. The cover plate component 10 is connected to one side surface of the middle frame 20. The cover plate component 10 is used to close the opening of the receiving groove 21, and the lens component 30 is located between the cover plate component 10 and the middle frame 20.

[0052] Please refer to the combination of Figure 7 and Figure 10 , Figure 7 shows Figure 1 An exploded view of the terminal structure component 100 provided by the illustrated embodiment, Figure 10 shows a schematic structural diagram of the middle frame 20 provided by the embodiment of the present application. When the lens component 30 is located in the receiving groove 21, the middle frame 20 and the cover plate component 10 enclose the lens component 30 to jointly realize the protection of the lens component 30, and avoid damage to the lens component 30 when it is subjected to an external impact force; at the same time, a sealed space is formed inside the receiving groove 21 to prevent external dust and other substances from entering the lens component 30 and affecting the imaging effect of the lens component 30.

[0053] The optical axis of the lens component 30 is the axis of symmetry of each component in the lens component 30. The lens component 30 includes a lens. The optical axis of the lens component 30 passes through the spherical center of the lens and is perpendicular to the mirror surface of the lens. At this spherical center point, there is no deflection between the incident light and the outgoing light of the lens. When the number of lenses in the lens component 30 is at least two, the optical axis of the lens component 30 passes through the spherical centers of at least two lenses.

[0054] Taking the extending direction of the optical axis of the lens component 30 as the first direction, the thickness direction of the middle frame 20 is the same as the first direction. One side surface of the middle frame 20 in the first direction (such as the X direction in Figure 2 and Figure 3 ) has a receiving groove 21, and a part of the lens component 30 is located in the receiving groove 21. The lens component 30 is fixed relative to the bottom wall of the receiving groove 21, and there is a spacing distance between the lens component 30 and the side wall of the receiving groove 21, which provides a larger space for the receiving groove 21 to receive the lens component 30, simplifies the installation of the lens component 30 in the receiving groove 21, and is also beneficial to avoiding interference between the lens component 30 and the side wall of the receiving groove 21.

[0055] Please refer to Figure 3 and Figure 4 , Figure 4 showsFigure 3 An enlarged view of the terminal structure component provided by the illustrated embodiment at 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 sequentially connected in the first direction. At least a part of the middle frame 20 is connected to at least a part of the first cover plate 11. The projected area of the first cover plate 11 in the first direction is less than or equal to the projected 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 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 coincides with the projection of the middle frame 20 in the first direction.

[0056] In one embodiment, the projected area of the first cover plate 11 in the first direction is less than the projected 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. And in the direction perpendicular to the first direction, there is a spacing distance between the first cover plate 11 and the four peripheral edges of the middle frame 20 (please refer to Figure 1 ). This avoids the first cover plate 11 protruding from the four peripheral edges of the middle frame 20, which is beneficial to improving the aesthetics of the terminal structure component 100. When the first cover plate 11 protrudes from the four peripheral edges of the middle frame 20, the protruding part of the first cover plate 11 is more likely to collide with the outside. Therefore, by having a spacing distance between the first cover plate 11 and the four peripheral edges of the middle frame 20, it is also beneficial to improve the service life of the first cover plate 11, avoiding the collision between the first cover plate 11 and the outside from affecting the connection stability between the first cover plate 11 and the middle frame 20, and further improving the structural stability of the terminal structure component 100.

[0057] Please refer to Figure 8 , Figure 8 which shows a schematic structural diagram of the first cover plate provided by the embodiment of the present application. The first cover plate 11 has a through hole 111. The through hole 111 penetrates the first cover plate 11 in the first direction. The through hole 111 communicates with the receiving groove 21. Part of the lens assembly 30 extends out from the opening of the receiving groove 21 in the first direction and is located within the through hole 111, so that a part of the lens assembly 30 is located in the receiving groove 21 of the middle frame 20, and another part of the lens assembly 30 is located in the through hole 111 of the first cover plate 11. Both the receiving groove 21 and the through hole 111 are 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 can satisfy the accommodation of the lens assembly 30 by the middle frame 20 and the first cover plate 11.

[0058] On the premise that the terminal structure component 100 can accommodate the lens component 30, a through hole 111 is provided on the first cover plate 11. The length of the lens component 30 and the thickness of the first cover plate 11 partially overlap in the first direction, so that the terminal structure component 100 reduces the thickness of the overlapping part of the lens component 30 and the first cover plate 11 in the first direction, and the thickness of the terminal structure component 100 in the first direction is reduced. Compared with the case where the through hole 111 is not provided on the first cover plate 11 and the lens component 30 is only located in the receiving groove 21 of the middle frame 20, in order to accommodate the lens component 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 component 30. In this way, the total thickness of the middle frame 20 and the first cover plate 11 in the first direction is reduced, that is, the thickness of the terminal structure component 100 in the first direction is reduced, which is conducive to realizing the thin and light of the terminal structure component 100 and improving the portability of the terminal structure component 100.

[0059] In some embodiments, there is a spacing distance between the lens component 30 and the inner wall of the through hole 111, which provides a larger space for the through hole 111 to accommodate the lens component 30, simplifies the installation of the first cover plate 11, and avoids interference between the first cover plate 11 and the lens component 30.

[0060] In one embodiment, please refer to Figure 5 and Figure 6 , Figure 5 which shows Figure 3 a schematic cross-sectional structure diagram of the middle frame 20 and the cover plate component 10 provided by the shown embodiment, Figure 6 which shows Figure 5 a cross-sectional view of the middle frame and the cover plate component at B-B provided by the shown embodiment. 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 Figure 5 the X direction in Figure 6 ) 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 (please refer to Figure 6 ). The edge of the through hole 111 protrudes from the edge of the opening of the receiving groove 21 in the direction perpendicular to the first direction to improve the uniformity of the coverage of the opening of the receiving groove 21 by the first cover plate 11.

[0061] Exemplarily, please refer to Figure 6 , the shapes of both the through hole 111 and the opening of the receiving groove 21 are square. 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.

[0062] By making the area of the through hole 111 smaller than the area of the opening of the receiving groove 21, the structures of the middle frame 20 and the first cover plate 11 are transitioned near the opening of the receiving groove 21, and the size of the through hole 111 is appropriately reduced, which is beneficial to improving the structural strength of the first cover plate 11 and ensuring that the first cover plate 11 has sufficient impact resistance, that is, ensuring the protection ability of the first cover plate 11 for the lens module 30. Exemplarily, the shapes of the through hole 111 and the opening of the receiving groove 21 are both circular, the centers of the through hole 111 and the opening of the receiving groove 21 are on the same straight line, this straight line extends 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.

[0063] Please refer to Figure 3 and Figure 7 , 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 closes the through hole 111, and the second cover plate 12 completely covers the through hole 111 in the first direction. Since a part of the second cover plate 12 corresponds to the through hole 111, the non-covered parts of the first cover plate 11 and the second cover plate 12 are connected. The first cover plate 11 can be entirely connected to the second cover plate 12, or a part of the first cover plate 11 can be connected to the second cover plate 12. Exemplarily, 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, and a part of the first cover plate 11 is connected to a part of the second cover plate 12.

[0064] The area of the second cover plate 12 is greater than or equal to the area of the through hole 111, that is, the projected area of the second cover plate 12 in the first direction is greater than or equal to the projected 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.

[0065] The second cover plate 12 is connected to the edge of the first cover plate 11 surrounding the through hole 111. In one embodiment, please refer to Figure 5 , the area of the second cover plate 12 is greater than the area of the through hole 111, and 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 Figure 5In the X direction, 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 beneficial to improving the connection stability between the second cover plate 12 and the first cover plate 11, making the structure of the cover plate assembly 10 more stable. The second cover plate 12 is not easily separated from the first cover plate 11, ensuring the sealing effect of the second cover plate 12 on the through hole 111, making the sealing performance inside the receiving groove 21 better, preventing 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 impact resistance of the first cover plate 11 and the second cover plate 12 is stronger, and the protection ability of the first cover plate 11 and the second cover plate 12 for the lens assembly 30 is also improved.

[0066] After 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 receiving groove 21. The second cover plate 12 and the bottom wall of the receiving groove 21 respectively apply forces in opposite directions along the first direction to the lens assembly 30. The second cover plate 12 and the bottom wall of the receiving groove 21 clamp and fix the lens assembly 30, and the lens assembly 30 is clamped between the second cover plate 12 and the bottom wall of the receiving groove 21, which is beneficial to further improving the position stability of the lens assembly 30.

[0067] 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 resist 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 communicating with the receiving groove 21, a part of the lens assembly 30 is located in the receiving groove 21, and another part of the lens assembly 30 extends out of the opening of the receiving groove 21 in the first direction and is located in the groove 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, 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 at the position where the groove is provided is small, so that the structural strength of the first cover plate 11 at the position where the groove is provided is low and it is easy to be damaged when being impacted; at the same time, there is a problem of stress concentration at the connection between the side wall and the bottom wall of the groove of the first cover plate 11, and it is easy to have a notch effect, resulting in poor impact resistance of the first cover plate 11, and further resulting in poor protection ability of the first cover plate 11 for the lens assembly 30. By making the terminal structure assembly 100 include the connected first cover plate 11 and the second cover plate 12, 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, which is not only beneficial to the partial overlap of the length of the lens assembly 30 and the thickness of the first cover plate 11 in the first direction and reduces the thickness of the terminal structure assembly 100 in the first direction, but also beneficial to improving the structural strength of the first cover plate 11 and the second cover plate 12, so that the external impact force received by the terminal structure assembly 100 is dispersed to the first cover plate 11 and the second cover plate 12, improving the impact resistance of the first cover plate 11 and the second cover plate 12, and further ensuring the protection ability of the first cover plate 11 and the second cover plate 12 for the lens assembly 30.

[0068] 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, thereby 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 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, and at least a portion of the first cover plate 11 is connected to a portion of the second cover plate 12, which is conducive to ensuring 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 protection ability of the cover plate assembly 10 and the middle frame 20 for 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 realizing the position fixation of the lens assembly 30.

[0069] 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. Part of the lens assembly 30 extends from the opening of the accommodating groove 21 in the first direction and is located in 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. On 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 realizing the lightness and thinness of the terminal structure assembly 100 and improving the portability of the terminal structure assembly 100.

[0070] For a possible implementation, see Figure 3 , Figure 7 and Figure 8 The first cover plate 11 has an outer surface 112, which is in the first direction (eg Figure 3 The outer surface 112 of the first cover plate 11 is a surface facing away from the middle frame 20 in the middle X direction, and has a first groove 113, that is, the opening and the bottom wall of the first groove 113 are arranged opposite to each other in the first direction.

[0071] 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. Exemplarily, the bottom wall of the first groove 113 can support and connect the second cover plate 12 simultaneously. Compared with the case where the bottom wall of the first groove 113 supports the second cover plate 12 and the side wall of the first groove 113 connects the second cover plate 12, making the bottom wall of the first groove 113 support and connect the second cover plate 12 simultaneously is beneficial to simplifying the connection process between the second cover plate 12 and the first cover plate 11. At the same time, since it is necessary to compress the thickness of the first cover plate 11 in the first direction, the side wall area of the first groove 113 is 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 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 beneficial to making full use of 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 large connection area, and further ensuring the stability of the connection structure between the second cover plate 12 and the first cover plate 11.

[0072] Please refer to Figure 8 , the first groove 113 surrounds the through hole 111, so that after the second cover plate 12 is connected to the bottom wall of the first groove 113, the through hole 111 can be closed, which is beneficial to simplifying the setting manner of the second cover plate 12. When the first groove 113 surrounds the through hole 111, the side wall of the first groove 113 surrounds the through hole 111, and there is a spacing distance between the side wall of the first groove 113 and the opening edge of the through hole 111 in the direction perpendicular to the first direction, so that the bottom wall of the first groove 113 has a certain area, ensuring the connection area between the second cover plate 12 and the bottom wall of the first groove 113. Compared with the case where the side wall of the first groove 113 is flush with the inner wall of the through hole 111, it is beneficial to improve the connection stability between the second cover plate 12 and the first cover plate 11.

[0073] The first groove 113 and the through hole 111 are communicated, that is, the through hole 111 is provided on the bottom wall of the first groove 113, which is beneficial to simplifying the setting manner of the first groove 113 and the through hole 111. The second cover plate 12 is attached and connected to the bottom wall of the first groove 113. At least a part of the second cover plate 12 is located in 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 is beneficial to realizing the thinning of the terminal structure assembly 100.

[0074] In one embodiment, please refer to Figure 4, in a direction perpendicular to the first direction, there is a spacing distance between the side wall of the second cover plate 12 and the side wall of the first groove 113, which provides a larger space for the first groove 113 to accommodate the second cover plate 12, provides a reserved clearance for the setting error of the first groove 113 and the manufacturing error of the second cover plate 12, avoids the situation where the second cover plate 12 cannot be installed into the first groove 113, and is conducive to simplifying the installation of the second cover plate 12 at the first groove 113. At the same time, it avoids the side walls of the second cover plate 12 and the first groove 113 from being in too close contact. When the first cover plate 11 and / or the second cover plate 12 expands due to heat, the first cover plate 11 and the second cover plate 12 press against each other at the contact position, resulting in damage to the first cover plate 11 and the second cover plate 12. It is conducive to providing space for the appropriate deformation of the first cover plate 11 and the second cover plate 12 and improving the service life of the first cover plate 11 and the second cover plate 12.

[0075] In a possible implementation manner, please refer to Figure 3 , Figure 7 , Figure 8 and Figure 9 , Figure 9 shows a side view of the first cover plate provided by the embodiment of the present application and a partial enlarged view thereof. There is a convex portion 114 on the outer surface 112 of the first cover plate 11. The convex portion 114 protrudes from the outer surface 112 in the 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 for one week. When the second cover plate 12 is located in the first groove 113, the convex portion 114 surrounds the second cover plate 12, and 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 position of the second cover plate 12 in a direction perpendicular to the first direction, which is conducive to improving the stability of the position of the second cover plate 12.

[0076] The convex portion 114 and the first cover plate 11 can be of an integral structure. The surface of the convex portion 114 close to the first groove 113 can have a spacing distance from the side wall 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; or the surface of the convex portion 114 close to the first groove 113 can form the side wall 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 convex portion 114 protrudes from the outer surface 112 in the first direction.

[0077] In one embodiment, the surface of the convex portion 114 close to the first groove 113 forms the side wall of the first groove 113, which is conducive to 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, so that the thickness of the second cover plate 12 in the first direction can be appropriately increased, which is conducive to improving the structural strength of the second cover plate 12. The impact resistance of the second cover plate 12 is enhanced, and further the protection ability of the second cover plate 12 for the lens assembly 30 is improved. Please refer to Figure 9 , the surface of the convex portion 114 away from the first groove 113 can be a smooth arc surface. The two sides of the arc surface in the first direction are respectively and smoothly connected to the surface of the convex portion 114 facing away from the outer surface 112 and the outer surface 112, and the arc surface is recessed toward the side close to the outer surface 112 to achieve a smooth transition in structure between the convex portion 114 and the outer surface 112 of the first cover plate 11, and improve the ornamental and touch feel of the first cover plate 11.

[0078] 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 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 in the first direction. The height of the convex portion 114 relative to the bottom wall of the first groove 113 is the maximum height by which the convex portion 114 protrudes from the bottom wall of the first groove 113 in the first direction. When the surface of the convex portion 114 close to the first groove 113 forms the side wall of the first groove 113, the height of the convex portion 114 relative to the bottom wall of the first groove 113 is the depth of the first groove 113.

[0079] 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 convex portion 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 conducive to the convex portion 114 protecting 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 convex portion 114 relative to the bottom wall of the first groove 113, so that a 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 out of the opening of the first groove 113 along the first direction, which is conducive to reducing the height of the convex portion 114 relative to the bottom wall of the first groove 113, that is, reducing the height of the convex portion 114 relative to the outer surface 112 of the first cover plate 11, so that the transition between the convex portion 114 and the outer surface 112 of the first cover plate 11 is smoother.

[0080] In one embodiment, please refer to Figure 5 , in the first direction (such as Figure 5In the X direction, 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 convex portion 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 convex portion 114 relative to the bottom wall of the first groove 113. The convex portion 114 is flush with the second cover plate 12 or protrudes from the second cover plate 12 in the first direction, and the convex portion 114 completely encloses the second cover plate 12, enabling the convex portion 114 to limit the position of the second cover plate 12, which is beneficial to improving the stability of the position of the second cover plate 12.

[0081] Please refer to Figure 3 , the second cover plate 12 closes the through hole 111, and part of the lens assembly 30 is located in the through hole 111, such that the second cover plate 12 and the lens assembly 30 are oppositely arranged in the first direction and the second cover plate 12 and the lens assembly 30 are in contact. When the side of the cover plate assembly 10 provided with the second cover plate 12 contacts an object such as the ground, since the convex portion 114 protrudes from the second cover plate 12 in the first direction, the convex portion 114 can contact the object such as the ground prior to the second cover plate 12, reducing the situation where the second cover plate 12 is impacted, and further reducing the situation where the lens assembly 30 in contact with the second cover plate 12 is impacted, which is beneficial to protecting the lens assembly 30. Exemplarily, the surface of the convex portion 114 close to the first groove 113 forms the side wall of the first groove 113, the second cover plate 12 is completely accommodated in the first groove 113, and the side wall of the first groove 113 limits the position of the second cover plate 12, which is beneficial to improving the stability of the position of the second cover plate 12.

[0082] In a possible implementation manner, please refer to Figure 5 , in the first direction, there is a spacing distance H1 between the bottom wall of the first groove 113 and the outer surface 112 of the first cover plate 11. The first cover plate 11 and the second cover plate 12 satisfy the relationship: H1 < H2. This spacing distance is less than the height of the second cover plate 12 relative to the bottom wall of the first groove 113, such that the second cover plate 12 protrudes from the first cover plate 11 in the first direction, which can appropriately reduce the depth of the first groove 113 in the first direction, ensure the thickness of the first cover plate 11 at the first groove 113, that is, ensure the structural strength of the first cover plate 11 at the first groove 113. The first cover plate 11 has a strong impact resistance, which is beneficial to ensuring the protection ability of the cover plate assembly 10 for the lens assembly 30.

[0083] When the thicknesses of the first cover plate 11 and the second cover plate 12 in the first direction remain unchanged, if the second cover plate 12 does not protrude from the first cover plate 11 in the first direction, the first cover plate 11 needs to be provided with a first groove 113 having a greater depth in the first direction to accommodate the second cover plate 12. The thickness of the first cover plate 11 at the first groove 113 decreases, reducing the structural strength of the first cover plate 11 at the first groove 113.

[0084] In the first direction, the thickness of the first cover plate 11, the thickness of the second cover plate 12, and the spacing 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 requirements to ensure the structural strength of the first cover plate 11 and the second cover plate 12 and avoid too large a step difference between the second cover plate 12 and the first cover plate 11, which affects the use experience. The step difference between the second cover plate 12 and the first cover plate 11 is the distance 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 in the first direction. 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 relatively smooth, and a convex portion 114 may not be provided on the outer surface 112 for transition.

[0085] In one embodiment, please refer to Figure 3 , the outer surface 112 of the first cover plate 11 has a convex portion 114. The surface of the convex portion 114 close to the first groove 113 forms 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 convex portion 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 convex portion 114 close to the first groove 113 forms the side wall of the first groove 113. This not only realizes the structural transition between the convex portion 114 for the second cover plate 12 and the first cover plate 11, making the surface of the cover plate assembly 10 on the side provided with the second cover plate 12 smoother, but also utilizes the height of the convex portion 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, so that the thickness of the first cover plate 11 at the first groove 113 is larger, 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 convex portion 114. This also makes it possible that when the side of the cover plate assembly 10 provided with the second cover plate 12 contacts an object such as the ground, the convex portion 114 can contact the object such as the ground prior to the second cover plate 12, reducing the situation where the second cover plate 12 is impacted, which is beneficial to protecting the lens assembly 30.

[0086] In one embodiment, please refer to Figure 3 and Figure 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 and 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.

[0087] In a possible implementation manner, please refer to Figure 5 , in the first direction, the thickness of the second cover plate 12 is less than the thickness of the first cover plate 11. Compared with the 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, and the depth of the first groove 113 in the first direction is smaller, so that the first cover plate 11 has a certain thickness at the first groove 113, ensuring the structural strength of the first cover plate 11 at the first groove 113. The first cover plate 11 has a strong impact resistance, which is beneficial to ensuring the protection ability of the cover plate assembly 10 for the lens assembly 30. At the same time, the smaller thickness of the second cover plate 12 also makes the height of the second cover plate 12 protruding from the outer surface 112 in the first direction smaller, which is not only beneficial to reducing the thickness of the cover plate assembly 10 in the first direction and realizing the miniaturization of the terminal structural assembly 100, but also makes the step difference between the first cover plate 11 and the second cover plate 12 smaller, and the structural transition between the second cover plate 12 and the first cover plate 11 is smoother, which is beneficial to ensuring that the cover plate assembly 10 has a better appearance and user experience.

[0088] Since 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 greater than the hardness of the first cover plate 11, ensuring the structural strength of the second cover plate 12 under the condition of a smaller thickness. On the premise of realizing a smaller thickness of the cover plate assembly 10 in the first direction, the protection ability of the cover plate assembly 10 for the lens assembly 30 is ensured.

[0089] In a possible implementation manner, please refer to Figure 3 , Figure 7 , Figure 10 and Figure 11 , Figure 11 shows Figure 10 the cross-sectional view of the middle frame at C-C and its partial enlarged view provided by the shown implementation manner. In the first direction (such as Figure 3 and Figure 11 the X direction in

[0090] 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 is also used to support the second cover plate 12. Similar to the design of the first groove 113 and the second cover plate 12, compared with the bottom wall of the second groove 22 supporting the first cover plate 11 and the side wall of the second groove 22 being connected to the first cover plate 11, the bottom wall of the second groove 22 simultaneously supports and connects the first cover plate 11, which is beneficial to simplifying the connection process between the first cover plate 11 and the middle frame 20. At the same time, the middle frame 20 is used to support the lens assembly 30 and the cover plate assembly 10, so that the middle frame 20 needs to have a certain thickness in the first direction to ensure the structural strength of the middle frame 20. The depth of the second groove 22 on the middle frame 20 is limited in the first direction, resulting in a smaller side wall area of the second groove 22. If the first cover plate 11 is connected to the side wall 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 to the bottom wall of the second groove 22 is beneficial to making full use of the space of the middle frame 20 perpendicular to the first direction, ensuring that the first cover plate 11 and the middle frame 20 have a large connection area, and further ensuring the stability of the connection structure between the cover plate assembly 10 and the middle frame 20.

[0091] 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 can be made opposite. When the first cover plate 11 and the middle frame 20 are connected, the side wall of the second groove 22 surrounds the middle frame 20, so that the side wall of the second groove 22 encloses the first cover plate 11 in the direction perpendicular to the first direction, realizing the protection of the first cover plate 11 by the middle frame 20 in the direction perpendicular to the first direction.

[0092] Please refer to Figure 10 and Figure 11 The second groove 22 communicates with the receiving groove 21, that is, the receiving groove 21 is provided on the bottom wall of the second groove 22, which is beneficial to simplifying the setting manner of the second groove 22 and the receiving groove 21. The first cover plate 11 is adhesively connected to the bottom wall of the second groove 22, and at least a part of the first cover plate 11 is located in the second groove 22. In the 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 structural component 100 in the first direction, which is beneficial to realizing the thin and light of the terminal structural component 100.

[0093] In one embodiment, please refer to Figure 3, in a direction perpendicular to the first direction, there is a spacing distance between the side wall of the first cover plate 11 and the side wall of the second groove 22, which provides a larger space for the second groove 22 to accommodate the first cover plate 11, provides a reserved gap for the setting error of the second groove 22 and the manufacturing error of the first cover plate 11, avoids the situation that the first cover plate 11 cannot be installed into the second groove 22, and is beneficial to simplifying the installation of the first cover plate 11 at the second groove 22. At the same time, it avoids the side walls of the first cover plate 11 and the second groove 22 from contacting too closely. When the first cover plate 11 and / or the middle frame 20 expand due to heat, the first cover plate 11 and the middle frame 20 press against each other at the contact position, resulting in damage to the first cover plate 11 and the middle frame 20. It is beneficial to provide space for the appropriate deformation of the first cover plate 11 and the middle frame 20 and improve the service life of the first cover plate 11 and the middle frame 20.

[0094] 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 may 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 may 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 out of the opening of the second groove 22 along the first direction, which is beneficial for reducing the depth of the second groove 22 and enabling the middle frame 20 to have a certain thickness to ensure the structural strength of the middle frame 20.

[0095] In one embodiment, please refer to Figure 3 , the bottom wall of the second groove 22 is provided with a second bonding member 262. The second bonding 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 and the middle frame 20. The second bonding 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 bonding member 262.

[0096] The design idea of the second groove 22 is similar to that of the first groove 113. Both can improve the connection stability of each component in the terminal structure component 100 and make the thicknesses of the two connected components at least partially overlap in the first direction, reduce the thickness of the terminal structure component 100 in the first direction, and thus realize the thinning and lightening of the terminal structure component 100.

[0097] In one possible implementation manner, please refer to Figure 3 , the projection of the second cover plate 12 in the first direction and the projection of the middle frame 20 in the first direction partially overlap. The middle frame 20 can indirectly support the second cover plate 12, so that both the middle frame 20 and the first cover plate 11 are used to support the second cover plate 12, which is beneficial for improving the stability of the position of the second cover plate 12.

[0098] In a possible implementation manner, please refer to Figure 10 and Figure 11 , on the surface of the middle frame 20 facing the first cover plate 11, there is a mating portion 24, and on the surface of the first cover plate 11 facing the middle frame 20, there is a mating structure corresponding to the mating portion 24. The mating structure on the first cover plate 11 and the mating portion 24 on the middle frame 20 are matingly connected, further improving the connection stability between the first cover plate 11 and the middle frame 20.

[0099] The mating portion 24 is located outside the receiving groove 21 and is disposed close to the receiving groove 21, so that the setting position of the mating portion 24 is close to the lens assembly 30, which is beneficial to increasing the connection stability 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 force, 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 the enclosure of the lens assembly 30, which is beneficial to improving the protection ability of the cover plate assembly 10 and the middle frame 20 for the lens assembly 30. The number of the mating portions 24 can be at least two, and at least two mating portions 24 are evenly disposed around the receiving groove 21.

[0100] In a possible implementation manner, please refer to Figure 3 and Figure 7 , 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 receiving groove 21. The second cover plate 12 and the bottom wall of the receiving groove 21 respectively apply forces in opposite directions along the first direction (such as Figure 3 the X direction in

[0101] ), and the second cover plate 12 and the bottom wall of the receiving groove 21 clamp and fix the lens assembly 30. The terminal structure assembly 100 further includes a buffer member 240, and the buffer member 240 is located between the lens assembly 30 and the second cover plate 12, so that the buffer member 240 is also located 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 member 240.

[0102] In one embodiment, the side of the lens assembly 30 close to the bottom wall of the accommodation groove 21 is the light incident side of the lens assembly 30, and the side of the lens assembly 30 close to the cover plate assembly 10 is the light exiting side of the lens assembly 30. The lens assembly 30 further includes a sensor chip. The sensor chip of the lens assembly 30 is located on the light exiting side of the lens assembly 30, that is, the sensor chip of the lens assembly 30 is close to the cover plate assembly 10. By providing a buffer member 240 between the second cover plate 12 and the lens assembly 30, the buffer member 240 can adjust the magnitude of the pressure exerted by the second cover plate 12 on the sensor chip of the lens assembly 30 through deformation, avoiding excessive pressure exerted by the second cover plate 12 on the sensor chip of the lens assembly 30 and causing damage to the sensor chip.

[0103] The present application also provides a terminal device 200. Please refer to Figure 12 , Figure 13 and Figure 14 . Figure 12 shows a schematic structural diagram of the terminal device 200 provided by the embodiment of the present application. Figure 13 shows Figure 12 a cross-sectional view of the terminal device 200 provided by the shown embodiment at D-D. Figure 14 shows Figure 13 an enlarged view of the terminal device 200 provided by the shown embodiment at c. The terminal device 200 includes the terminal structure assembly 100 and the screen 210 described in any of the above embodiments. The screen 210 is located on one side of the terminal structure assembly 100 in the first direction (such as Figure 13 and Figure 14 the X direction in).

[0104] The screen 210 is connected to the middle frame 20 of the terminal structure assembly 100, and the screen 210 is located on the side of the middle frame 20 away from the cover plate assembly 10, such that the middle frame 20 is located between the screen 210 and the cover plate assembly 10.

[0105] In one embodiment, please refer to Figure 14, the cover plate assembly 10, the middle frame 20, and the screen 210 are sequentially connected in the first direction. The projected areas of the cover plate assembly 10 and the screen 210 in the first direction are both smaller than the projected area of the middle frame 20 in the first direction. The projections of the cover plate assembly 10 and the screen 210 in the first direction are both located within the projection range of the middle frame 20 in the first direction. And in the direction perpendicular to the first direction, there are spacing distances between the cover plate assembly 10 and the screen 210 and the four peripheral edges of the middle frame 20. This avoids the cover plate assembly 10 and the screen 210 protruding from the four peripheral edges of the middle frame 20, which is beneficial to improving the aesthetics of the terminal device 200; at the same time, it avoids the cover plate assembly 10 and the screen 210 being prone to collision with the outside world, and realizes the protection of the cover plate assembly 10 and the screen 210 by the middle frame 20.

[0106] In one embodiment, please refer to Figure 11 and Figure 14 , the surface of the middle frame 20 facing away from the first cover plate 11 has a third groove 14. The opening and the bottom wall of the third groove 14 are oppositely arranged in the first direction (such as Figure 11 and Figure 14 the X direction in

[0107] The lens hole 23 penetrates through the bottom wall of the receiving groove 21 and the bottom wall of the third groove 14, so that the receiving groove 21, the lens hole 23, and the third groove 14 are sequentially connected. 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 that the screen 210 and the middle frame 20 have a large connection area, and further ensure the stability of the connection between the screen 210 and the middle frame 20. The third groove 14 surrounds the lens hole 23, so that the screen 210 can close the lens hole 23 after being connected to the bottom wall of the third groove 14, which is beneficial 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 walls of the third groove 14 enclose the screen 210, and limit the screen 210 in the direction perpendicular to the first direction, which is beneficial to improving the stability of the position of the screen 210.

[0108] In a possible implementation manner, please refer to Figure 10 , Figure 11 and Figure 14, the bottom wall of the receiving groove 21 has a lens hole 23, the lens hole 23 penetrates the bottom wall of the receiving groove 21 along the first direction, and the lens hole 23 communicates with the receiving groove 21. Part of the lens assembly 30 is located in the lens hole 23, so that a part of the lens assembly 30 is located in the receiving groove 21 of the middle frame 20, and another part of the lens assembly 30 is located in the lens hole 23 at the bottom wall of the receiving groove 21. Both the receiving groove 21 and the lens hole 23 are used to accommodate the lens assembly 30.

[0109] The screen 210 closes the lens hole 23, that is, the screen 210 completely covers the lens hole 23 in the first direction. The area of the screen 210 is greater than or equal to the area of the lens hole 23, that is, 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 hole 23 in the first direction. At the same time, the projection of the edge of the lens hole 23 in the first direction is located within the projection range of the screen 210 in the first direction. By closing the lens hole 23 with the screen 210, the sealing of the lens assembly 30 by the cover plate assembly 10, the middle frame 20 and the screen 210 is ensured, and the sealing performance inside the receiving groove 21 is good, avoiding the entry of external dust and other substances into the lens assembly 30 and ensuring the imaging effect of the lens assembly 30.

[0110] The screen 210 has a light-transmitting area, and the light-transmitting area is disposed opposite to the lens hole 23 in the first direction, so that external light can enter the lens assembly 30 through the light-transmitting area and the lens hole 23 to realize the imaging of the lens assembly 30. In one embodiment, the side of the lens assembly 30 close to the bottom wall of the receiving groove 21 is the light incident side of the lens assembly 30, and the side of the lens assembly 30 close to the cover plate assembly 10 is the light exit side of the lens assembly 30. The areas of the lens hole 23 and the light-transmitting area are both larger than the area of the light incident hole of the lens assembly 30, avoiding the middle frame 20 and the screen 210 from blocking the light incident of the lens assembly 30 and enabling external light to smoothly enter the lens assembly 30.

[0111] Please refer to Figure 14 and Figure 15 , Figure 15 shows Figure 12 an exploded view of the terminal device provided by the embodiment shown. In the first direction, the surface of the screen 210 facing the middle frame 20 has an avoidance groove 211. The opening and the bottom wall of the avoidance groove 211 are disposed opposite to each other in the first direction. The avoidance groove 211 communicates with the lens hole 23, and the lens assembly 30 protrudes from the lens hole 23, so that a part of the lens assembly 30 extends out of the lens hole 23 in the first direction and is located in the avoidance groove 211.

[0112] A part of the lens assembly 30 is located in the receiving groove 21 of the middle frame 20, and another part of the lens assembly 30 is located in 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, a part of the lens assembly 30 is located in the through hole 111 of the first cover plate 11, a part is located in the receiving groove 21, a part is located in the lens hole 23, and a part is located in 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.

[0113] On the premise of meeting the accommodation of the lens assembly 30 by the terminal device 200, an avoidance groove 211 is provided 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 is reduced in the first direction of the terminal device 200, and the thickness of the terminal device 200 in the first direction is reduced, which is beneficial to realizing the thin and light of the terminal device 200 and improving the portability of the terminal device 200.

[0114] In one embodiment, please refer to Figure 14 , the bottom wall of the avoidance groove 211 and the lens assembly 30 have a spacing distance in the first direction, which provides a larger space for the avoidance groove 211 to accommodate the lens assembly 30, and is beneficial to simplifying the setting method of the screen 210; at the same time, it avoids the contact between the bottom wall of the avoidance groove 211 and 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 realizing the protection of the screen 210 for the lens assembly 30.

[0115] In a possible implementation manner, please refer to Figure 16 and Figure 17 , Figure 16 shows a schematic structural diagram of the terminal device 200 provided by the embodiment of the present application without the first cover plate 11, Figure 17 shows Figure 12 a cross-sectional view of the terminal device 200 provided by the shown embodiment at E-E and a partial enlarged view thereof.

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 Figure 17In the X direction, 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 along the opposite direction of the first direction, so that the first abutting portion 221 and the second abutting portion 25 respectively apply forces towards each other 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 beneficial to further improve the stability of the position of the lens assembly 30.

[0116] In a possible implementation manner, please refer to Figure 13 、 Figure 14 、 Figure 15 and Figure 18 , Figure 18 which shows a schematic structural diagram of the positioning member 230 provided by the embodiment of the present application. The terminal device 200 further includes a positioning member 230. The positioning member 230 is located in the receiving groove 21. The positioning member 230 is connected to the bottom wall of the receiving groove 21. At least part of the positioning member 230 is located between the lens assembly 30 and the bottom wall of the receiving groove 21, and the lens assembly 30 is fixed to the positioning member 230.

[0117] The positioning member 230 has a positioning hole 233, and the positioning hole 233 communicates with the lens hole 23. The lens assembly 30 sequentially passes through the positioning hole 233 and the lens hole 23 in the first direction (such as Figure 13 and Figure 14 the X direction in), 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 this straight line extends along the first direction. When assembling the terminal device 200, first align the center of the positioning hole 233 and the center of the lens hole 23, and then make the optical axis of the lens assembly 30 pass through the center of the positioning hole 233, that is, the positioning of the position setting of the lens assembly 30 can be realized, and the accuracy of the assembly of the lens assembly 30 can be improved.

[0118] In an embodiment, please refer to Figure 18 ,the positioning member 230 has a first part 231 and a second part 232 connected to each other.

The first part 231 is connected to the bottom wall of the receiving groove 21. The first part 231 has a positioning hole 233. The second part 232 extends from the first part 231 towards the opening direction of the receiving groove 21. The second part 232 surrounds the lens assembly 30. There is a spacing between the second part 232 and the lens assembly 30 to simplify the installation of the lens assembly 30 relative to the positioning member 230 and protect the lens assembly 30. The second part 232 does not extend out of the opening, so that the positioning member 230 is completely received in the receiving groove 21 to avoid the positioning member 230 interfering with the setting of other components. Exemplarily, there is a spacing between the second part 232 and the opening of the receiving groove 21.

[0119] In one embodiment, please refer to Figure 14 , the terminal device 200 further includes a third adhesive member 263 and a seal member 250, and both the third adhesive member 263 and the seal member 250 are located in 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 for bonding the positioning member 230 and the middle frame 20. The seal member 250 is located between the first portion 231 and the lens assembly 30, and the lens assembly 30 and the positioning member 230 clamp the seal member 250. The seal member 250 has elasticity, so that both the seal member 250 and the buffer member 240 can adjust the magnitude of the pressure applied to the lens assembly 30 by the cover plate assembly 10 and the middle frame 20 through deformation, avoiding damage to the lens assembly 30.
