In order to facilitate the distinction, the end face of the first step 1123 away from the second step 1124 is set as the first end face 1125, and the first end face 1125 is provided with a light entrance 1126; The second step 1124 is connected to the first step 1123 , and the diameter of the end face of the second step 1124 close to the first step 1123 is larger than the diameter of the first end face 1125 of the first step 1123 . The bosses 1121 are connected to the second steps 1124 and distributed outside the second steps 1124 in the circumferential direction, and their diameter is larger than that of the second steps 1124 , that is, from the bosses 1121 to the second steps 1124 and then to the first steps 1123 . The diameters are successively reduced, so that the volume of the lens barrel 112 can be reduced as a whole. The lens unit 111 includes at least one lens, and the lens is at least partially accommodated in the convex ring 1122 ; the diaphragm 113 is accommodated in the convex ring 1122 and is flush with the first end surface 1125 of the first step 1123 . The diaphragm 113 refers to the entity that restricts the light beam in the optical system, and it can be the edge of a lens, a frame or a specially arranged screen with holes.

In one embodiment, the number of lenses in the lens unit 111 may be set as required, for example, it may include one lens, or may include multiple lenses, which is not limited here. The lens can only be accommodated in the convex ring 1122 , or can be extended from the convex ring 1122 to the boss 1121 , and can be set as required. For the convenience of description, in this embodiment, the lens in the lens unit 111 close to the first end surface 1125 of the first step 1123 is denoted as the first lens, the first lens is accommodated in the convex ring 1122, and the top surface of the lens of the lens unit 111 Protruding toward the light entrance 1126 . The light entrance 1126 can be concave into the lens barrel 112 to form a concave area, the lens of the lens unit 111 is exposed in the concave area, and the top surface of the lens can be higher than the first end surface 1125, and can also be flush with the first end surface 1125 or lower than the first end surface 1125. One end face 1125. The second step 1124 is indirectly connected to the boss 1121 . Specifically, a transition portion is provided between the second step 1124 and the boss 1121 , and the cross-sectional diameter of the transition portion gradually decreases from the boss 1121 toward the second step 1124 . Moreover, the end face of the transition portion connected to the second step 1124 is the same diameter as the end face of the second step 1124 , and the end face of the transition portion connected to the boss 1121 is smaller than the end face of the boss 1121 to reduce the volume of the lens barrel 112 . In a specific application, the first step 1123, the second step 1124, the transition portion and the boss 1121 are all arranged coaxially. Of course, according to actual needs, the second step 1124 can also be directly connected to the boss 1121 .

Referring to FIG. 6 , in an embodiment, the camera 11 may be applied to the terminal device 10 , for example, the terminal device 10 may be a mobile phone, and the camera 11 may be applied to the mobile phone as a front camera. As the screen-to-body ratio of the display screen 12 of the mobile phone becomes higher and higher, the size of the opening of the camera in the display screen 12 (ie the camera through hole 121 ) becomes more and more important. 12 has a higher screen-to-body ratio. The size of the camera through hole 121 of the display screen 12 needs to correspond to that of the camera 11 , so that ambient light can smoothly enter the camera 11 through the camera through hole 121 . Referring to FIG. 5, generally, the following relationship exists between the aperture diameter A of the display screen 12 and the camera 11:

Among them, FOV is the field of view of the camera;

B is the depth of field of view of the camera;

C is the distance from the front end of the camera to the lower surface of the display screen, usually set to 0.15mm.

It can be seen from formula (1) that the aperture diameter A of the display screen 12 depends on the field angle FOV, the field angle depth B and the distance C between the camera 11 and the display screen 12 .

At present, the distance between the diaphragm 113 in the camera 11 and the first lens is relatively small, about 0.1 mm. At this time, the distance between the diaphragm 113 and the first end face 1125 is relatively large, that is, the diaphragm 113 is always set relative to the lens. The top surface is recessed in the convex ring 1122 to reduce stray light and increase the relative illuminance. When the viewing angle FOV is 80.7°, the viewing angle depth B is 1.43 mm, and the aperture diameter A of the display screen 12 is 2.8 mm. It can be seen that the aperture diameter A of the display screen 12 is too large to be further reduced, resulting in The screen ratio of the display screen 12 cannot be further increased.

In this embodiment, the position of the diaphragm 113 is completely designed, so that the diameter of the opening of the display screen 12 can be reduced. By setting the diaphragm 113 to be flush with the first end face 1125 of the first step 1123, the distance between the diaphragm 113 and the first lens can be greatly increased, for example, the distance between the diaphragm 113 and the first lens can be determined by 0.1mm is increased to 0.32mm, at this time the depth of field of view B can be reduced from 1.43mm to 0.99mm, still considering the case where the field of view angle FOV is 80.7°, according to formula (1), the opening of display screen 12 can be obtained. The value of the hole diameter A is reduced from 2.8 mm to 1.913 mm, so that the opening diameter A of the display screen 12 can be greatly reduced, which helps to improve the screen ratio of the display screen 12 . Of course, the distance between the diaphragm 113 and the first lens can be set as required, and is not limited to the above situation.

In one embodiment, the distance between the diaphragm 113 and the first lens is 0.2 mm˜0.5 mm, the field of view FOV of the camera 11 is 75°˜85°, and the depth B of the field of view of the camera 11 is correspondingly 0.5 mm˜1.2 mm, the diameter A of the opening of the display screen 12 can be at least 1.6 mm to 2.1 mm. Compared with the existing 2.8 mm, the diameter A of the opening of the display screen 12 is greatly reduced, so the display screen 12 can be greatly improved. screen ratio.

Further, since the diaphragm 113 in this embodiment is set flush with the first end face 1125 where the light entrance 1126 is located, compared with the current camera, the position of the diaphragm 113 is raised, so that the front end surface of the convex ring 1122 is raised. The thickness of the meat increases, and without affecting the lens unit 111 in the lens barrel 112, the front end surface of the convex ring 1122 can be cut to make the wall thickness thinner, thereby forming the first step 1123, and the convex ring 1122 is not The cut part forms a second step 1124 , and the diameter of the first step 1123 gradually decreases from close to the second step 1124 to its first end face 1125 , so that the head diameter of the camera 11 can be reduced.

Referring to FIG. 4 , in one embodiment, the diameter d1 of the first end surface 1125 of the first step 1123 is 1.9 mm˜2.3 mm, and the end surface of the second step 1124 close to the first step 1123 is the second head step surface. The diameter d2 of the step surface of the second head is 2.5mm to 3.0mm; while the diameter of the head of the existing camera can only be 3.7mm at a minimum, and cannot be further reduced. Therefore, this embodiment can effectively reduce the head diameter of the camera 11. When the camera 11 is applied to the terminal device 10, more space can be saved for the terminal device 10, and the screen ratio can be increased.

Referring to FIG. 4 , in one embodiment, the depth h1 of the first step 1123 is 0.1 mm˜0.5 mm, eg, 0.23 mm; the depth h2 of the second step 1124 is 0.7 mm˜1.0 mm, eg, may be 0.7 mm. When the size of the convex ring 1122 is within the above range, the overall size of the camera 11 can be made smaller, so that the layout of the components inside the terminal device 10 to which the camera 11 is applied can be compacted, thereby facilitating the thinning of the terminal device 10 .

In one embodiment, the camera 11 further includes an image sensor. The image sensor can be installed in the boss 1121 or on the side of the boss 1121 that faces away from the boss ring 1122. The specific position can be set and fixed as required.

Of course, the sealing member 17 may also have other shapes, such as rectangles or other polygons or other special-shaped structures. The sealing member 17 can also be extended between the display screen 12 and the support 16, or between the middle frame 13 and the support 16, so that the gap between the display screen 12 and the camera 11 and the support 16 is sealed , or the gap between the middle frame 13 and the camera 11 and the support 16 is sealed, so as to improve the reliability of waterproof and dustproof.

Referring to FIG. 9, in one embodiment, the terminal device 10 further includes a cover plate 18. The cover plate 18 may be made of glass or sapphire. The lens unit 111 of 11 plays a better protective role. The cover plate 18 may have a 2D structure or a 3D structure, and the cover plate 18 of the 3D structure can make the terminal device 10 have a better appearance effect. Further, an OCA (Optically Clear Adhesive, optical adhesive) layer may be disposed between the cover plate 18 and the display screen 12 , so that the cover plate 18 and the display screen 12 are connected reliably and the display effect of the display screen 12 will not be adversely affected.

In one embodiment, the thickness of the cover plate 18 may be less than or equal to 0.55 mm, and the thickness of the OCA layer may be less than or equal to 0.15 mm.

It can be understood that whether there is an intermediate layer between the two layers should be regarded as being stacked in sequence. For example, an adhesive layer may be provided between the screen and the foam layer. At this time, the screen, the foam layer and the heat dissipation layer should still be considered. stacked in sequence. It can be understood that, due to the use of the OLED screen, the thickness of the display screen 12 can be made smaller, which is beneficial to the reduction of the overall thickness of the terminal device 10 and the thinning of the terminal device 10 .

In one embodiment, the cover plate 18 includes a front surface and a rear surface disposed opposite to each other, the rear surface is close to the display screen 12 , the boundary of the field angle of the camera 11 intersects with the rear surface to form an intersection line, and the intersection line and the edge of the display screen 12 The minimum distance between them is less than 1.0mm. Further, the minimum distance between the intersection line and the edge of the display screen 12 may be less than 0.5 mm. Furthermore, the minimum distance between the intersection line and the edge of the display screen 12 may be less than 0.3 mm. The setting of this distance can make the display screen 12 as close to the optical axis of the lens unit 111 as possible without blocking the field of view of the camera 11 . It can be understood that the boundary of the field of view and the line of intersection formed with the rear surface are virtual surfaces or lines, but the field of view is determined by the structure of the camera 11 , and this parameter can be obtained by measurement.

In one embodiment, the display screen 12 has a plane area, and the plane on which the display screen 12 is located is taken as the reference plane, and the orthographic projection of the first end face 1125 where the light entrance 1126 of the convex ring 1122 is located on the reference plane is the same as that of the display screen 12 . The orthographic projections of the faces partially overlap. The above-mentioned terminal device 10 and the camera 11 can be set close to the edge of the terminal device 10. Since the orthographic projection of the first end face 1125 where the light entrance 1126 is located on the reference plane overlaps with the orthographic projection of the display screen 12 on the reference plane, the edge of the display screen 12 overlaps. It can be as close as possible to the edge of the terminal device 10 to reduce the width of the black border between the edge of the display screen 12 and the frame 131, and to increase the screen ratio while making the width of the black border on the periphery of the display screen 12 more consistent, so as to improve the The appearance integrity of the terminal device 10 . Since there is no need to provide a driving mechanism for the camera, the internal structure of the terminal device 10 is not complicated by the driving mechanism.

Referring to FIG. 9 , in one embodiment, the terminal device 10 further includes a main board 15 , and the main board 15 is disposed on the side of the displayable area facing away from the display screen 12 . Specifically, the main board 15 can be fixedly connected to the on the middle frame 13. The main board 15 is provided with a notch 151 penetrating the edge of the main board, and the camera 11 is provided with the notch 151. This structure can avoid stacking the camera 11 on the main board 15, thereby reducing the overall thickness of the terminal device 10 and facilitating the terminal Thinning of the device 10 .

6 to 9 , in one embodiment, the boundary of the field of view of the camera 11 intersects the rear surface to form an intersection line, and the minimum distance between the intersection line and the inner edge of the frame 131 is 0.1 mm˜0.6 mm. Further, the minimum distance between the intersection line and the inner edge of the frame 131 is 0.2 mm˜0.5 mm. Further, the minimum distance between the intersection line and the inner edge of the frame 131 and the minimum distance between the intersection line and the edge of the display screen 12 can be set to be consistent, so as to prevent the inner edge of the frame 131 from viewing the field of view of the camera 112. cause occlusion. Of course, when the minimum distance between the intersection line and the inner edge of the frame 131 is within the above range of values, the light entrance 1126 of the camera 11 can also be brought close to the edge of the terminal device 10 to increase the screen ratio of the terminal device 10. And can maintain the integrity of the display area. And since there is no need to provide a driving mechanism for the camera 11, the internal structure of the terminal device 10 will not become complicated due to the driving mechanism.
