[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0033] To address the aforementioned technical problems, this disclosure provides a lens structure, a camera module, and an electronic device. The lens structure includes a lens barrel body and at least one clearance structure. The clearance structure is disposed on the outer wall of the lens barrel body and is formed by recessing or tilting the outer wall in a direction away from the light-incident side of the lens barrel body. In this embodiment, a portion of the outer wall of the lens barrel body is recessed or tilted in the direction of the light-incident side of the lens barrel body to form a clearance structure outside the lens structure. In the assembled state, the device clearance space formed by the clearance structure can accommodate the target device in the electronic device, which helps to improve the overall structural compactness and achieve miniaturization and thinning design.

[0034] According to an exemplary embodiment, such as Figure 1 As shown, this embodiment provides a lens structure 10, which can be applied to electronic devices with image acquisition functions such as smartphones, tablets, and laptops.

[0035] See Figure 1 The lens structure 10 includes a lens barrel body 11, which is cylindrical in shape. Its inner wall encloses a mounting space for installing and protecting optical components (such as an optical system composed of multiple lenses 13). Its outer wall forms the external contour of the lens barrel body 11. The lens barrel body 11 can be cylindrical (see [reference]). Figure 1 It can also be L-shaped or other shapes, but its specific shape is not strictly limited in this embodiment.

[0036] See Figure 1The lens structure 10 includes at least one clearance structure 12, which is disposed on the outer wall of the lens barrel body 11. The clearance structure 12 forms a device clearance space 10a. In the assembled state (i.e., when the lens structure 10 is installed in an electronic device), a portion of the structure of a first preset device (described in detail below) in the electronic device can extend into the device clearance space 10a, thereby shortening the distance between the geometric centers of the lens structure 10 and the first preset device, fully utilizing the gap space between the lens structure 10 and the first preset device, and improving the integration and compactness of the electronic device. The clearance structure 12 can be manufactured on the outer wall of the lens barrel body 11 by machining or integral molding.

[0037] In some embodiments, see Figure 1 The avoidance structure 12 is formed by a portion of the outer wall structure recessing in the direction away from the light-incident side of the lens body. The recessed avoidance structure 12 can be in the form of a groove or a rounded chamfer.

[0038] In other embodiments, see Figure 1 The avoidance structure 12 is formed by tilting a portion of the outer wall towards the light-incident side away from the lens body. The tilted avoidance structure 12 can be presented in the form of a chamfer.

[0039] In this embodiment, a portion of the outer wall of the lens barrel body is recessed or inclined toward the light-incident side of the lens barrel body to form an avoidance structure outside the lens structure. In the assembled state, the device avoidance space formed by the avoidance structure can accommodate the target device in the electronic device, which helps to improve the overall structural compactness.

[0040] In one exemplary embodiment, such as Figure 1 As shown, this embodiment provides a lens structure 10, which includes a lens barrel body 11 and at least one clearance structure 12. The lens barrel body 11 is used to mount a lens 13. The clearance structure 12 is disposed on the outer wall of the lens barrel body 11 and is formed by recessing or tilting from the outer wall toward the light-incident side away from the lens barrel body 11.

[0041] Among them, such as Figure 1 As shown, along the axial direction of the main body 11 of the lens barrel ( Figure 1 (as shown in the z-direction), the lens barrel body 11 includes a first barrel 111 and a second barrel 112 connected together. The outer diameter of the first barrel 111 is larger than the outer diameter of the second barrel 112. By setting the outer diameter of the first barrel 111 to be larger than the outer diameter of the second barrel 112, interference with the lens inside the lens barrel body 11 can be avoided when processing the avoidance structure 12. In some embodiments, along Figure 1 In the z-direction shown, the first cylinder 111 is disposed on the side of the second cylinder 112 away from the light-incident side.

[0042] See Figure 1 Due to the difference in outer diameter between the first cylindrical body 111 and the second cylindrical body 112, a stepped surface 113 is formed at the connection between them. See one example. Figure 1 An exemplary embodiment shows a stepped surface 113 perpendicular to the optical axis direction. In other possible embodiments, the plane containing the stepped surface 113 may also be set to have any angle within the range of 60°-90° with the optical axis direction.

[0043] In this embodiment, see Figure 1 The clearance structure 12 is formed by the chamfer between the outer wall of the first cylindrical body 111 and the stepped surface 113. See one example. Figure 1 and Figure 3 An example is shown with a 45° chamfer. The plane containing the 45° chamfer forms a 45° angle with the optical axis. The angle of the chamfer can be adaptively set according to the shape of the first preset device, for example, it can be any value between 30° and 60°.

[0044] In some embodiments, such as Figure 1 As shown, the clearance structure 12 is an inclined plane, which is a flat surface that forms a non-right angle with the optical axis of the lens structure 10. The inclined plane can be formed, for example, by obliquely cutting the lens body. Since the first preset device in the electronic device usually has a straight edge, by setting the inclined plane in this embodiment, it can be ensured that the distance between each position of the edge of the first preset device and the inclined plane is equal, so as to make full use of the device clearance space 10a and improve compactness.

[0045] In other embodiments (not shown in the figures), the avoidance structure is an inclined surface arranged around the circumference of the first cylinder. In one example, the inclined surface only surrounds a portion of the outer perimeter of the first cylinder, such as each inclined surface surrounding approximately 90°. In another example, the inclined surface surrounds the entire circumference of the first cylinder, that is, the inclined surface surrounds 360°.

[0046] Among them, such as Figure 3 As shown, the lens structure 10 also includes an elastic protective member 14, which is sleeved on the outer wall of the lens barrel body 11 and fits against the outer wall of the lens barrel body 11. The material of the elastic protective member 14 includes, but is not limited to, silicone, rubber, etc.

[0047] See Figure 3 ,along Figure 1In the z-direction shown, the elastic protective member 14 protrudes from the second barrel 112 of the lens barrel body 11, forming a crater structure with the second barrel 112. In the assembled state, the protruding part of the elastic protective member 14 can abut against the components in the electronic device, thereby achieving a seal that is waterproof and dustproof, to prevent external impurities from entering the second barrel 112 and affecting normal image acquisition. In one example, when the lens structure 10 is used as a front-facing camera of an electronic device, the protruding part of the elastic protective member 14 can abut against the non-display side of the display screen 200 of the electronic device.

[0048] See Figure 3 The shape of the elastic protective member 14 is designed based on the outer contour of the lens barrel body 11 where the clearance structure 12 is provided. It is understood that since the device clearance space 10a formed by the clearance structure 12 needs to accommodate specific electronic devices, in some alternative embodiments, the thickness of the portion of the elastic protective member 14 covering the clearance structure 12 can be set to be less than the thickness of other portions, so as to reduce the space occupied by the elastic protective member 14 in the device clearance space 10a, thereby optimizing the internal space layout of the electronic device.

[0049] In one exemplary embodiment, such as Figure 1 As shown, this embodiment provides a lens structure 10, which includes a lens barrel body 11 and at least one clearance structure 12. The lens barrel body 11 is used to mount a lens 13. The clearance structure 12 is disposed on the outer wall of the lens barrel body 11 and is formed by recessing or tilting from the outer wall toward the light-incident side away from the lens barrel body 11.

[0050] The lens structure 10 provided in this embodiment includes each of the structures of the lens structure 10 provided in any of the foregoing embodiments.

[0051] See Figure 1 In the lens structure 10, among the multiple lenses 13, at least one lens 13 is a high-refractive-index lens 13 with a refractive index greater than or equal to 1.67. The refractive index of the high-refractive-index lens 13 can be, for example, 1.67, 1.68, etc. In this embodiment, the lens 13 is configured to have a large refractive index, giving it stronger refractive power. Based on this, even if the thickness of the lens 13 is reduced (… Figure 1 Even in the z-direction shown, the optical performance of the lens 13 can still be guaranteed. This allows for a reduction in the overall thickness of the lens structure 10 by thinning the lens 13, thereby reducing the space occupied by the lens structure 10 within the electronic device. This facilitates the miniaturization of the electronic device and enhances its aesthetic appeal.

[0052] Among them, such as Figure 1As shown, the field of view of lens 13 is set to be greater than or equal to 95°, and the focal length of lens 13 is set to be less than or equal to 2.5mm. It is understood that the overall length of the lens is generally proportional to the focal length of lens 13; by reducing the focal length of lens 13, a smaller overall lens length can be achieved, thereby reducing the thickness of the lens structure 10. Figure 1 (as shown in the z-direction).

[0053] In one example, the refractive index of lens 13 is set to 1.68, the field of view is set to 100°, and the focal length is set to 2.16mm. In this embodiment, by adjusting the refractive index, field of view, and focal length of lens 13, the thickness of lens structure 10 is reduced by approximately 0.63mm compared to related technologies.

[0054] According to exemplary embodiments of this disclosure, such as Figure 4 and Figure 5 As shown, this embodiment also provides a camera module 100, which includes a substrate and a lens structure 10 provided in any of the foregoing embodiments of this disclosure, along the optical axis direction of the lens structure 10 ( Figure 4 (as shown in the z-direction), the lens structure 10 is stacked with the substrate.

[0055] The camera module 100 provided in this embodiment has all the technical features and effects of the lens structure 10. The camera module 100 provided in this embodiment can be used as both a front camera and a rear camera of an electronic device.

[0056] Compared with camera modules 100 in related technologies, this camera module 100, in its assembled state, has a component clearance space 10a that can avoid specific electronic components of the electronic device, optimizing the internal space stacking of the electronic device and improving the overall structural compactness. Furthermore, the camera module 100 is thinner and occupies less space in the thickness direction of the electronic device, facilitating a slimmer and lighter design. When the camera module 100 is used as a rear camera of the electronic device, it can achieve a flush back cover, enhancing the device's aesthetic appeal.

[0057] In some alternative implementations, see Figure 4 and Figure 5 Because the camera module 100 is thinner, the second preset device 70 in the electronic device can be stacked with the camera module 100. The second preset device 70 may be a motherboard, a small board, a heat sink, etc.

[0058] In some embodiments, such as Figure 4 and Figure 5As shown, the base of the camera module 100 includes a lens substrate 30 and a lens mount 20 connected together. The lens substrate 30 includes structures such as a printed circuit board 31 and a flexible circuit board 32. The printed circuit board 31 can provide mechanical support and electrical connection for the image sensor 33. The flexible circuit board 32 is electrically connected to the printed circuit board 31. The flexible circuit board 32 can be bent and deformed to bypass electronic devices in electronic devices and realize wiring in complex spaces.

[0059] See Figure 4 and Figure 5 The lens mount 20 and the printed circuit board 31 of the lens substrate 30 are fastened together to form an accommodating space to cover the image sensor 33 and provide protection.

[0060] See Figure 4 and Figure 5 The lens mount 20 is equipped with a focusing motor (not shown in the attached figure), an image stabilization structure (not shown in the attached figure), etc. The lens mount 20 is connected to the lens structure 10 through the focusing motor and the image stabilization structure. For example, the focusing motor can drive the lens to move relative to the image sensor 33, thereby completing the focus adjustment.

[0061] According to exemplary embodiments of this disclosure, such as Figure 2 and Figure 3 As shown, this embodiment also provides an electronic device, such as a smartphone, tablet computer, laptop computer, or any other electronic product with image acquisition capabilities. The electronic device includes a mid-frame 300 and a preset device, as well as a lens structure 10 or camera module 100 provided in any of the foregoing embodiments of this disclosure. Both the lens structure 10 and the camera module 100 are disposed in the mid-frame 300. The first preset device is disposed in the mounting space defined by the mid-frame 300, and at least a portion of the structure of the first preset device extends into the device clearance space 10a formed by the lens structure 10.

[0062] The electronic device provided in this embodiment has all the technical features and effects of the lens structure 10 and camera module 100 provided in any of the foregoing embodiments of this disclosure, and will not be repeated here.

[0063] In some embodiments, see Figure 2 and Figure 3The electronic device includes a display screen 200, which includes a glass cover 40, a screen substrate 50, and a shielding cover 60. The glass cover 40 is the outermost structure of the display screen 200, used to protect the screen substrate 50 from scratches, dirt, etc. The screen substrate 50 includes a touch layer, a display layer, a driver IC, a backlight layer, etc. The shielding cover 60 covers the side of the screen substrate 50 opposite to the glass cover 40 and covers the side of the screen substrate 50. The shielding cover 60 has the functions of electromagnetic shielding and physical protection of the screen substrate 50. The first preset device is at least one of the screen substrate 50 and the shielding cover 60 of the display screen 200. In the assembled state, the screen substrate 50 or the shielding cover 60 can be configured to partially extend into the device clearance space 10a formed by the lens structure 10, avoiding structural interference, improving the integration and compactness of the electronic device, and facilitating the miniaturization and thinning design requirements of the electronic device.
