Description

Technical Field

[0001] This application relates to the field of optical imaging technology, specifically to a reflective component, a periscope camera module, and an electronic device. Background Technology

[0002] Periscope camera modules are widely used in smartphones, security monitoring, and automotive imaging. Their core feature is the ability to change the direction of light by folding light through a prism, thus achieving long focal length or special angle imaging within a limited space. A typical periscope module consists of a prism and multiple lenses. In existing technologies, the prism is fixed by a separate prism bracket, while the lens at the prism's front end (closer to the object being photographed) is mounted in another lens bracket, with the two assembled via a mechanical structure. However, this split bracket configuration requires reserved installation space and tolerance clearances, making it difficult to further compress the horizontal or vertical dimensions of the periscope camera module, thus failing to meet the demands for thinner and lighter consumer electronics devices. Utility Model Content

[0003] In view of the above, it is necessary to propose a reflective component, a periscope camera module, and an electronic device to reduce the size of the reflective component, thereby meeting the requirements for thinner and lighter electronic devices.

[0004] A first aspect of this application provides a reflective assembly, including a reflector and a support. The reflector reflects light propagating along a first optical axis to a direction propagating along a second optical axis. The support carries the reflector and includes a first support portion, a second support portion, and a pair of side supports. The first support portion extends in a plane perpendicular to the first optical axis, the second support portion extends in a plane perpendicular to the second optical axis, and the side supports extend in a plane parallel to the first and second optical axes to connect the first and second support portions and form a receiving cavity. The first support portion has a light entrance hole opening along the first optical axis, and the second support portion has a light entrance hole opening along the second optical axis. The light exit hole is open; the reflective assembly further includes a first lens, which is disposed on the first support and covers the light entrance hole; the reflector is located in the receiving cavity and connected to the side baffle, the reflector has an optically effective area and an optically ineffective area disposed around the optically effective area, the optically effective area is disposed opposite to the first lens, and is used to reflect light passing through the first lens out of the light exit hole, the optically ineffective area has a clearance portion formed by cutting an edge, the first support has a support area near the clearance portion, the clearance portion abuts against the support area, and at least a portion of the projection of the clearance portion and the support area on a plane parallel to the second optical axis and perpendicular to the first optical axis overlaps.

[0005] In the reflective assembly provided in this application embodiment, by placing the reflector in the receiving cavity and placing it opposite to the first lens, and by having at least a portion of the projection of the clearance portion and the bearing area on a plane parallel to the second optical axis and perpendicular to the first optical axis overlap, the thickness of the optical path and periscope camera module of the traditional split structure is reduced, the size of the reflective assembly is compressed, and the requirements for thinner and lighter electronic devices are met; the clearance portion formed by the chamfer of the optically ineffective area precisely abuts against the bearing area of ​​the support portion, which not only avoids damage to the optically effective area, but also ensures that the installation angle of the reflector is precisely controllable, so that the incident light can be stably reflected at the designed angle after passing through the first lens, thus ensuring imaging accuracy.

[0006] In one possible implementation, the clearance portion includes a beveled edge structure, and the bearing area has a beveled surface adapted to the beveled edge structure.

[0007] In the solution provided in this application embodiment, the combination of the beveled edge structure and the beveled surface of the bearing area, and the angle matching design of the beveled surface, can automatically correct the positional deviation of the reflector during installation, ensuring the strict alignment of the optical effective area with the first lens; the wedge locking effect formed by the beveled surface can effectively resist the displacement of the reflector caused by vibration or impact, and the contact stability is high.

[0008] In one possible implementation, the beveled edge structure includes an outwardly protruding arcuate structure, or the beveled edge structure includes at least two sequentially connected planar structures, or the beveled edge structure includes at least one planar structure and at least two outwardly protruding arcuate structures, with an arcuate structure connected to each of the opposite sides of each planar structure.

[0009] In the solution provided in this application embodiment, by using an outwardly convex arc-shaped structure as a beveled edge, the arc-shaped structure can adaptively adjust the contact pressure with the bearing area, and the geometric characteristics of the arc-shaped surface allow the reflector to automatically fine-tune to the optimal angle position during installation. By employing a beveled edge structure with multiple planes combined, multiple plane structures form a stepped positioning reference, which can reduce installation angle deviation. By setting a composite structure combining planes and arcs, the plane structure provides a rigid positioning reference, while the arc-shaped structure forms an elastic buffer; the combined effect of the two can reduce the displacement of the reflector under vibration.

[0010] In one possible implementation, the bearing area of ​​the first support portion is provided with anti-slip texture.

[0011] In the solution provided in this application embodiment, by setting anti-slip texture in the bearing area, the anti-slip texture can increase the static friction coefficient between the reflector and the bearing area, effectively preventing micro-displacement caused by vibration or impact.

[0012] In one possible implementation, the clearance portion includes a stepped edge structure, and the bearing area includes a stepped support surface corresponding to the stepped edge structure.

[0013] In the solution provided in this application embodiment, the combination of the stepped edge structure and the stepped support surface, the multiple mechanical constraints formed by the stepped structure can reduce the displacement amplitude caused by high-frequency vibration and ensure the stability of the optical path.

[0014] In one possible implementation, the reflector includes a face mirror, a prism, a square mirror, or a polygonal mirror.

[0015] The solution provided in this application embodiment adapts to various reflector types, including prisms that can achieve 90° optical path folding and polygon mirrors that support multi-directional beam control, thus meeting the optical path design requirements of different application scenarios.

[0016] In one possible implementation, the reflective component further includes:

[0017] The second lens is disposed on the second support portion and covers the light-transmitting hole. The second lens is disposed opposite to the reflector and is used to allow light emitted by the reflector to pass through and exit the light-exiting hole.

[0018] In the solution provided in this application embodiment, by integrating a second lens, the second lens and the reflector work together to form a closed optical channel, effectively reducing stray light interference. Furthermore, the second lens can correct aberrations in the reflected beam.

[0019] In one possible implementation, the reflective component further includes:

[0020] An adhesive element is bonded between the end of the reflector away from the relief portion and the second support portion.

[0021] In the solution provided in this application embodiment, by adding an adhesive to fix the end of the reflector away from the relief part, the adhesive and the relief part form a double fixing mechanism, which can ensure the fixed connection between the reflector and the support base and improve the impact resistance of the reflector.

[0022] A second aspect of this application provides a periscope camera module, comprising:

[0023] The reflective component as described above;

[0024] A lens assembly, fixed to the exit end of the reflective assembly; and

[0025] A photosensitive component is fixed to the side of the lens assembly opposite to the reflective component.

[0026] The periscope camera module provided in this application includes the aforementioned reflective component. The reflective component is configured by placing a reflector in a receiving cavity and positioning it opposite to the first lens. The projection of the clearance portion and the support area on a plane parallel to the second optical axis and perpendicular to the first optical axis overlaps at least partially. This reduces the optical path and thickness of the traditional split-structure periscope camera module, compresses the size of the reflective component, and meets the requirements for thinner and lighter electronic devices. The clearance portion formed by the cut edge of the optically ineffective area precisely abuts against the support area of ​​the support portion, which avoids damage to the optically effective area and ensures that the installation angle of the reflector is precisely controllable. This allows the incident light to be stably reflected at the designed angle after passing through the first lens, ensuring imaging accuracy.

[0027] A third aspect of this application provides an electronic device, including: a housing; and a periscope camera module as described above, the periscope camera module being disposed within the housing.

[0028] The electronic device provided in this application includes the aforementioned reflective component. The reflective component reduces the thickness of the optical path and periscope camera module of the traditional split structure by placing the reflector in the receiving cavity and placing it opposite to the first lens. The relief portion and the support area overlap at least partially on a plane parallel to the second optical axis and perpendicular to the first optical axis. This reduces the size of the reflective component and meets the requirements for thinner and lighter electronic devices. The relief portion formed by the cut edge of the optically ineffective area precisely abuts against the support area of ​​the support portion, which avoids damage to the optically effective area and ensures that the installation angle of the reflector is precisely controllable. This allows the incident light to be stably reflected at the designed angle after passing through the first lens, thus ensuring imaging accuracy. Attached Figure Description

[0043] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0044] Please see Figure 1 The first aspect of this application provides a reflective assembly 10, including a support base 11, a first lens 12, and a reflector 13.

[0045] Please see also Figure 2 and Figure 3The reflector 13 is used to reflect light propagating along the first optical axis L1 to propagate along the second optical axis L2. The support base 11 carries the reflector 13. The support base 11 includes a support portion 111, a second support portion 1121, and a pair of side baffles 1122. The support portion 111 is generally plate-shaped. The first support portion 111 extends in a plane perpendicular to the first optical axis L1. The second support portion 1121 is also generally plate-shaped and extends in a plane perpendicular to the second optical axis L2. The side baffles 1122 are also generally plate-shaped and extend in a plane parallel to the first optical axis L1 and the second optical axis L2, connecting the first support portion 111 and the second support portion 1121 to form a receiving cavity 1121a. The first support portion 111 has a light inlet hole 113 opening along the first optical axis L1, and the second support portion 1121 has a light outlet hole 114 opening along the second optical axis L2. The first lens 12 is disposed on the first support portion 111 and covers the light entrance hole 113. The reflector 13 is located in the receiving cavity 1121a and connected to the side baffle portion 1122. The reflector 13 has an optically effective area 131 and an optically ineffective area 132 disposed around the optically effective area 131. The optically effective area 131 is disposed opposite to the first lens 12 and is used to reflect the light passing through the first lens 12 out to the light exit hole 114. The optically ineffective area 132 has a clearance portion 1321 formed by cutting an edge. The first support portion 111 has a bearing area 1111 near the clearance portion 1321. The clearance portion 1321 abuts against the bearing area 1111. At least a portion of the projection of the clearance portion 1321 and the bearing area 1111 on a plane parallel to the second optical axis L2 and perpendicular to the first optical axis L1 overlaps.

[0046] In the reflective assembly 10 provided in this application embodiment, by placing the reflector 13 in the receiving cavity 1121a and placing it opposite to the first lens 12, and by having at least a portion of the projection of the clearance portion 1321 and the support area 1111 on a plane parallel to the second optical axis L2 and perpendicular to the first optical axis L1 overlap, the optical path of the traditional split structure and the thickness of the periscope camera module are reduced, the size of the reflective assembly 10 is compressed, and the requirements for the thinness and lightness of electronic devices are met. The clearance portion 1321 formed by the chamfer of the optically ineffective area 132 precisely abuts against the support area 1111 of the support portion 111, which not only avoids damage to the optically effective area 131, but also ensures that the installation angle of the reflector 13 is precisely controllable, so that the incident light can be stably reflected at the designed angle after passing through the first lens 12, thus ensuring imaging accuracy.

[0047] In this embodiment, the support portion 111 has a first receiving groove 1112 that communicates with the light entrance hole 113. The first lens 12 is disposed at the bottom of the first receiving groove 1112. The minimum vertical distance between the clearance portion 1321 and the bottom of the first receiving groove 1112 is in the range of 0.01mm to 0.2mm.

[0048] In one possible implementation, the reflective assembly 10 further includes a second lens 14. The second lens 14 is disposed on the second support portion 1121 and covers the light exit hole 114. The second lens 14 is disposed opposite to the reflector 13 and is used to allow light emitted by the reflector 13 to pass through and exit the light exit hole 114. The function of the second lens 14 is to converge the light.

[0049] In the solution provided in this application embodiment, by integrating a second lens 14, the second lens 14 and the reflector 13 work together to form a closed optical channel, effectively reducing stray light interference. Furthermore, the second lens 14 can perform aberration correction on the reflected beam.

[0050] In this embodiment, the second support portion 1121 is provided with a second receiving groove 1122a that communicates with the light output hole 114, and the second lens 14 is disposed at the bottom of the second receiving groove 1122a.

[0051] In one possible implementation, the reflective assembly 10 further includes an adhesive 15, which is bonded to one end of the reflective member 13 away from the relief portion 1321 and between the second support portion 1121.

[0052] In the solution provided in this application embodiment, by adding an adhesive 15 to fix the end of the reflector 13 away from the relief portion 1321, the adhesive 15 and the relief portion 1321 form a double fixing mechanism, which can ensure the fixed connection between the reflector 13 and the support base 11 and improve the impact resistance of the reflector 13.

[0053] In this embodiment, the adhesive 15 is an adhesive strip or is formed by curing optical adhesive.

[0054] In some embodiments, the adhesive 15 may be adhered to the side of the reflector 13 adjacent to the relief portion 1321 and the second support portion 1121.

[0055] In one possible implementation, the bearing area 1111 of the support portion 111 is provided with anti-slip texture 1111b.

[0056] In the solution provided in this application embodiment, by setting anti-slip texture 1111b in the bearing area 1111, the anti-slip texture 1111b can increase the static friction coefficient between the reflector 13 and the bearing area 1111, effectively preventing micro-displacement caused by vibration or impact.

[0057] Please see also Figure 4 In one possible implementation, the clearance portion 1321 includes a beveled edge structure 1321a, and the bearing area 1111 has a beveled surface 1111a adapted to the beveled edge structure 1321a.

[0058] In the solution provided in this application embodiment, the cooperation between the beveled edge structure 1321a and the beveled surface 1111a of the bearing area 1111, and the angle matching design of the beveled surface 1111a, can automatically correct the positional deviation of the reflector 13 during installation, ensuring the strict alignment of the optical effective area 131 and the first lens 12; the wedge locking effect formed by the beveled surface cooperation can effectively resist the displacement of the reflector 13 caused by vibration or impact, and the contact stability is high.

[0059] Please see also Figure 5 In one possible implementation, the beveled edge structure 1321a includes an outwardly protruding arcuate structure 1321a1. Specifically, Figure 5 The beveled edge structure 1321a in (a) includes only the outwardly protruding arc surface structure 1321a1. The radius of the arc surface structure 1321a1 can be set according to actual needs, for example, the radius can be set to 9.5mm. By using the outwardly protruding arc surface structure 1321a1 as the beveled edge, the arc surface structure 1321a1 can adaptively adjust the contact pressure with the bearing area 1111, and the geometric characteristics of the arc surface allow the reflector 13 to automatically fine-tune to the optimal angle position during installation.

[0060] In one possible implementation, the beveled edge structure 1321a includes at least two sequentially connected planar structures 1321a2. Specifically, Figure 5 In (b), the beveled edge structure 1321a consists of only three sequentially connected planar structures 1321a2, in which case the beveled edge structure 1321a is approximately C-shaped. By employing a multi-planar combination of beveled edge structure 1321a, multiple planar structures 1321a2 form a stepped positioning reference, which can reduce the installation angle deviation.

[0061] In one possible implementation, the beveled edge structure 1321a includes at least one planar structure 1321a2 and at least two outwardly protruding arcuate structures 1321a1, with an arcuate structure 1321a1 connected to opposite sides of each planar structure 1321a2. Specifically, Figure 5 The beveled edge structure 1321a in (c) includes a planar structure 1321a2 and two outwardly protruding arcuate structures 1321a1. Each side of the planar structure 1321a2 is connected to an arcuate structure 1321a1. In this case, the beveled edge structure 1321a is essentially a planar structure 1321a2 with rounded corners at both ends. By setting a composite structure combining planar and arcuate surfaces, the planar structure 1321a2 provides a rigid positioning reference, while the arcuate structures 1321a1 form an elastic buffer. Their combined effect can reduce the displacement of the reflector 13 under vibration.

[0062] Please see also Figure 6In one possible implementation, the clearance portion 1321 includes a stepped edge structure 1321a3, and the bearing area 1111 includes a stepped support surface 1111c corresponding to the stepped edge structure 1321a3. The stepped edge structure 1321a3 abuts against the stepped support surface 1111c to enhance the vibration resistance of the reflector 13.

[0063] In the solution provided in this application embodiment, the stepped edge structure 1321a3 and the stepped support surface 1111c cooperate to form multiple mechanical limits, which can reduce the displacement amplitude caused by high frequency vibration and ensure the stability of the optical path.

[0064] In one possible implementation, the reflector 13 includes a mirror, a prism, a square mirror, or a polygonal mirror. See also... Figure 7 , Figure 7 The reflector 13 in (a) is a mirror. Figure 7 The reflector 13 in (b) is a prism. Figure 7 The reflector 13 in (c) is a square mirror. Figure 7 The reflector 13 in (d) is a polygonal mirror.

[0065] In the solution provided in this application embodiment, by adapting to various reflector types 13, including prisms that can achieve 90° optical path folding and polygon mirrors that support multi-directional beam control, the optical path design requirements of different application scenarios are met.

[0066] In the reflective assembly 10 of this application embodiment, the reflective element 13 is pre-cut, and the position of the cut edge is designed to avoid interference, so that it can be integrally assembled with the first lens 12 on the support base 11. The assembly space is small and the generation of tolerances can be reduced.

[0067] Please see Figure 8 A second aspect of this application provides a periscope camera module 100, including a reflective assembly 10, a lens assembly 20, and a photosensitive assembly 30. The lens assembly 20 is fixed to the emitting end of the reflective assembly 10. The photosensitive assembly 30 is fixed to the side of the lens assembly 20 opposite to the reflective assembly 10.

[0068] The periscope camera module 100 provided in this application includes the aforementioned reflective component 10. The reflective component 10 is configured by placing the reflector 13 in the receiving cavity 1121a and opposite to the first lens 12. The clearance portion 1321 and the bearing area 1111 have at least partial projections on a plane parallel to the second optical axis L2 and perpendicular to the first optical axis L1. This reduces the optical path and thickness of the periscope camera module 100 of the traditional split structure, compresses the size of the reflective component 10, and meets the requirements for thinner and lighter electronic devices. The clearance portion 1321 formed by the chamfer of the optically ineffective area 132 precisely abuts against the bearing area 1111 of the support portion 111, which not only avoids damage to the optically effective area 131, but also ensures that the installation angle of the reflector 13 is precisely controllable, so that the incident light can be stably reflected at the designed angle after passing through the first lens 12, thus ensuring imaging accuracy.

[0069] Please see Figure 9 A third aspect of this application provides an electronic device 1000, including a housing 200 and a periscope camera module 100, the periscope camera module 100 being disposed within the housing 200. The electronic device 1000 may be, but is not limited to, a mobile phone, tablet computer, laptop computer, smartwatch, monitor, robot vacuum cleaner, etc.

[0070] The electronic device 1000 provided in this application embodiment includes the aforementioned reflective component 10. The reflective component 10 reduces the thickness of the optical path and periscope camera module 10 of the traditional split structure by placing the reflector 13 in the receiving cavity 1121a and opposite to the first lens 12, and the clearance portion 1321 and the bearing area 1111 overlap in at least part of their projection on a plane parallel to the second optical axis L2 and perpendicular to the first optical axis L1, thereby compressing the size of the reflective component 10 and meeting the requirement of thinness and lightness of the electronic device 1000. The clearance portion 1321 formed by the chamfer of the optically ineffective area 132 precisely abuts against the bearing area 1111 of the support portion 111, which not only avoids damage to the optically effective area 131, but also ensures that the installation angle of the reflector 13 is precisely controllable, so that the incident light can be stably reflected at the designed angle after passing through the first lens 12, thus ensuring imaging accuracy.
