[0002] With the continuous development of electronic technology, periscope lens assemblies have played an increasingly important role in people's lives. However, in actual use, when light propagates in the optical path of the periscope lens assembly, the structural parts in the periscope lens assembly usually block the light, causing the light to diffract, which in turn leads to poor imaging effect of the image finally formed by the periscope lens assembly. Summary of the invention

[0003] The present application aims to provide a periscope lens assembly, an electronic device and a method for manufacturing a periscope lens assembly to solve the problem of poor imaging effect of an image formed by the periscope lens assembly.

In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means that the objects connected before and after are in an "or" relationship.

[0022] See also Figure 1 , Figure 1 A schematic diagram of the structure of a periscope lens assembly provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the periscope lens assembly includes: a light transmission component 20 and a light guiding component 10, wherein the light guiding component 10 is fixedly connected to the light transmission component 20, a light incident surface is provided at the first end of the light guiding component 10 away from the light transmission component 20, and a light shading medium 11 is provided at the edge of the light incident surface.

[0023] The working principle of the embodiment of the present application can be seen in the following description:

[0024] Since a light incident surface is provided at the first end of the light guiding component 10 away from the light transmission component 20, and a light shading medium 11 is provided at the edge of the light incident surface, when the incident light beam is irradiated from the light incident surface into the light guiding component 10, the light shading medium 11 can optimize the light field distribution of the incident light beam, thereby reducing the noise and edge oscillation of the diffraction pattern, weakening the diffraction order energy of the incident light beam, reducing the interference of the diffracted light on the image finally formed by the periscope lens assembly, and thereby enhancing the imaging effect of the image finally formed by the periscope lens assembly.

[0025] Among them, the light transmission component 20 can be used to transmit the incident light beam, and the specific type of the light transmission component 20 is not limited here. Optionally, the light transmission component 20 may include at least one of the following: an imaging lens and a prism. The prism can be tilted or rotated relative to the imaging lens, so as to turn the propagation direction of the incident light beam; and the imaging lens can focus the target object in the external environment onto the optical path corresponding to the incident light beam to complete the propagation and imaging of the incident light beam.

[0026] It should be noted that the setting positions of the light guide component 10 and the light transmission component 20 may not be limited, that is, the incident light beam may pass through the light guide component 10 and the light transmission component 20 in sequence, or the incident light beam may also pass through the light transmission component 20 and the light guide component 10 in sequence.

[0027] The specific method of fixedly connecting the light guide component 10 and the light transmission component 20 is not limited herein. Optionally, the light guide component 10 and the light transmission component 20 can be bonded. Alternatively, the light guide component 10 and the light transmission component 20 can be snapped together.

[0028] The light shielding medium 11 may be fixed to the edge of the light incident surface. For example, the light shielding medium 11 may be bonded to the edge of the light incident surface by glue.

[0029] As an optional implementation, the distribution density of the light-shielding medium 11 close to the center of the light-incident surface is smaller than the distribution density of the light-shielding medium 11 far from the center of the light-incident surface.

[0030] The distribution density of the light-shielding medium 11 at any position close to the center of the light-incident surface is greater than the distribution density of the light-shielding medium 11 at any position far from the center of the light-incident surface.

[0031] For example: the light incident surface includes a first position and a second position, the first position is set close to the center of the light incident surface, the second position is set away from the center of the light incident surface, and the distance between the first position and the center of the light incident surface is smaller than the distance between the second position and the center of the light incident surface, so that the distribution density of the light-shielding medium 11 at the first position is smaller than the distribution density of the light-shielding medium 11 at the second position.

[0032] In the embodiment of the present application, the distribution density of the shading medium 11 can gradually increase along the direction from the center of the light incident surface to the edge position of the light incident surface, that is, the distribution density of the shading medium 11 can be gradually changed. At the same time, since the distribution density of the shading medium 11 gradually increases, the transmittance of the incident light beam gradually decreases, thereby further optimizing the light field distribution of the incident light beam, further reducing the noise and edge oscillation of the diffraction pattern, weakening the diffraction order energy of the incident light beam, reducing the interference of the diffracted light on the image finally formed by the periscope lens assembly, and further enhancing the imaging effect of the image finally formed by the periscope lens assembly.

[0033] It should be noted that, compared with the method of setting silk screen printing at the edge of the light transmission component 20, the embodiment of the present application can reduce the occurrence of long diffraction and water ripple diffraction stray light caused by silk screen printing blocking light, thereby further enhancing the imaging effect of the image finally formed by the periscope lens assembly.

[0034] It should be noted that the shape formed by the light-shielding medium 11 at the edge of the light-incident surface is not limited here. Optionally, the light-shielding medium 11 can form an arc-shaped or semicircular light-shielding area.

[0035] As another optional implementation, the light-shielding medium 11 forms an annular light-shielding area, and the light-transmitting area of ​​the light incident surface is located within the annular light-shielding area.

[0036] The incident light beam may pass through the light-transmitting area and irradiate into the light transmission component 20 .

[0037] In the embodiment of the present application, since the shading medium 11 forms an annular shading area, when the incident light beam is incident on any edge position of the light incident surface, it will pass through the shading medium 11, thereby ensuring that the diffraction phenomenon of the incident light beam is reduced, thereby further enhancing the imaging effect of the image finally formed by the periscope lens assembly.

[0038] Optionally, the transmittance of the annular light-shielding area is less than or equal to 10%, the transmittance of the light-transmitting area is greater than or equal to 90%, and the transmittance difference between any two positions in the light-transmitting area may be within 5%.

[0039] In addition, the width relationship between the annular light-shielding area and the light-transmitting area on the light-entering surface meets the following requirements. For details, see Figure 2 :

[0040] 1%≤((H2-H1) / H2*100%)≤50%;

[0041] Among them, H2 is used to represent the width of the annular light-shielding area on the light-incident surface, and H1 is used to represent the width of the light-transmitting area on the light-incident surface.

[0042] It should be noted that the specific shape of the light-transmitting area is not limited here. Optionally, the shape of the light-transmitting area can be circular, rectangular, elliptical or track-shaped (ie, a combination of two arcs and two rectangles).

[0043] In addition, the shading medium 11 can form an annular shading area, and the light-transmitting area of ​​the light incident surface is located within the annular shading area, that is, the annular shading area can enclose the light-transmitting area, for example: when the light-transmitting area is a rectangular light-transmitting area, the annular shading area can enclose the above-mentioned rectangular light-transmitting area; or, the shading medium 11 can only partially surround the light-transmitting area, for example: when the light-transmitting area is a rectangular light-transmitting area, the shading medium 11 can only be located on one side of the long side or short side of the rectangular light-transmitting area.

[0044] As an optional implementation, the shading medium 11 is a magnetic shading medium. In this way, the distribution density of the magnetic shading medium on the light incident surface can be conveniently adjusted by magnetic force, so that the distribution density of the shading medium 11 has a better gradual change effect.

[0045] As an optional implementation, the magnetic light-shielding medium is ferrosoferric oxide, or the magnetic light-shielding medium includes at least one of the following: ferrite, neodymium iron boron and samarium cobalt.

[0046] The magnetic light-shielding medium may also be a black inorganic substance similar to ferroferric oxide, or the magnetic light-shielding medium may also include metal materials similar to ferrite, neodymium iron boron and samarium cobalt, that is, the magnetic light-shielding medium may be a mixture of multiple metal materials.

[0047] In the implementation manner of the present application, the magnetic light-shielding medium is ferroferric oxide, or the magnetic light-shielding medium includes at least one of the following: ferrite, neodymium iron boron and samarium cobalt, thus increasing the diversity of the magnetic light-shielding medium.

[0048] As an optional implementation, the light-guiding component 10 is provided with a light-emitting surface at the second end close to the light-transmitting component 20 , and the light-shielding medium 11 is provided at the edge of the light-emitting surface.

[0049] The first end and the second end may be two ends disposed opposite to each other, that is, the light incident surface and the light emitting surface are respectively disposed on the two ends disposed opposite to each other.

[0050] The incident light beam may sequentially pass through the light incident surface, the interior of the light guide component 10 and the light emitting surface to irradiate the light transmission component 20 .

[0051] In the embodiment of the present application, a shading medium 11 is provided at the edge of the light emitting surface, so that the light field distribution effect of the incident light beam can be further optimized, the noise of the diffraction pattern and the oscillation of the edge can be further reduced, the diffraction order energy of the incident light beam can be weakened, and the interference of the diffracted light on the image finally formed by the periscope lens assembly can be reduced, thereby further enhancing the imaging effect of the image finally formed by the periscope lens assembly.

[0052] An embodiment of the present application also provides an electronic device, including the periscope lens assembly in the above embodiment. Since the electronic device provided by the embodiment of the present application also includes the periscope lens assembly in the above embodiment, it has the same beneficial technical effects as the above embodiment, and the specific structure of the periscope lens assembly can refer to the corresponding description in the above embodiment, which will not be repeated here.

[0053] As an optional embodiment, the electronic device further includes a control component, a driving component and a magnetic component, the control component being connected to the magnetic component and at least one of the light-guiding components included in the periscope lens assembly through the driving component, and the control component drives the magnetic component and at least one of the light-guiding components to move through the driving component to adjust the distribution position of the magnetic light-shielding medium included in the periscope lens assembly at the edge position of at least one of the light incident surface and the light exit surface of the light-guiding component.

[0054] Among them, the control component can be a control component separately set in the electronic device for adjusting the distribution position of the magnetic shading medium, or the control component can also be the central processing unit of the electronic device, that is, the central processing unit can integrate other control functions and the function for adjusting the distribution position of the magnetic shading medium.

[0055] The specific type of the driving member is not limited herein. Optionally, the driving member may be a connecting rod mechanism, or the driving member may be a combination of a gear and a connecting rod, etc.

[0056] In an embodiment of the present application, during the use of the electronic device, the control component can drive at least one of the magnetic component and the light-guiding component to move through the driving component to dynamically adjust the distribution position of the magnetic light-shielding medium included in the periscope lens assembly at the edge position of at least one of the light incident surface and the light exit surface of the light-guiding component, thereby making the adjustment method of the distribution position of the magnetic light-shielding medium more flexible.

[0057] As an optional implementation, a first accommodating member is disposed at an edge of the light incident surface of the light guide component, the first accommodating member includes a first hollow cavity, and the magnetic light-shielding medium is disposed in the first hollow cavity.

[0058] In an embodiment of the present application, the first housing member includes a first hollow cavity, and a magnetic light-shielding medium is arranged in the first hollow cavity. In this way, when at least one of the magnetic member and the light-guiding member moves, the distribution position of the magnetic light-shielding medium in the first middle frame cavity can be adjusted under the magnetic force of the magnetic member. Compared with the method of fixing the magnetic light-shielding medium with a glue layer, the embodiment of the present application can more flexibly and conveniently adjust the distribution position of the magnetic light-shielding medium in the first middle frame cavity according to actual usage during the use of the electronic device, thereby further reducing the noise and edge oscillation of the diffraction pattern, weakening the diffraction order energy of the incident light beam, reducing the interference of the diffracted light on the image finally formed by the periscope lens assembly, and further enhancing the imaging effect of the image finally formed by the periscope lens assembly.

[0059] As an optional implementation, a second container is disposed at an edge of the light emitting surface of the light guide component, the second container includes a second hollow cavity, and the magnetic light-shielding medium is disposed in the second hollow cavity.

[0060] In the embodiment of the present application, when at least one of the magnetic part and the light-guiding part moves, the distribution position of the magnetic light-shielding medium in the second middle frame cavity can be adjusted under the magnetic force of the magnetic part, so that the distribution position of the magnetic light-shielding medium in the second middle frame cavity can be further flexibly and conveniently adjusted, thereby further reducing the noise and edge oscillation of the diffraction pattern, weakening the diffraction order energy of the incident light beam, and reducing the interference of the diffracted light on the image finally formed by the periscope lens assembly, thereby further enhancing the imaging effect of the image finally formed by the periscope lens assembly.

[0061] The first accommodating member and the second accommodating member may be respectively disposed at two opposite ends of the light guide component, and the structures of the first accommodating member and the second accommodating member may be the same.

[0062] As an optional implementation, both the first accommodating member and the second accommodating member are annular members.

[0063] The shapes of the first and second containers can match the shape of the light guide component, that is, if the light guide component is cylindrical, the first and second containers can be circular rings; or, if the light guide component is a rectangular column, the first and second containers can be rectangular rings.

[0064] In this way, the magnetic light-shielding medium can be distributed in all directions in the first receiving member and the second receiving member, thereby further enhancing the imaging effect of the image finally formed by the periscope lens assembly.

[0065] As an optional embodiment, the magnetic part includes a first magnetic part and a second magnetic part, the light guiding component is arranged between the first magnetic part and the second magnetic part, and the polarity of the magnetic pole of the first magnetic part facing the end of the light guiding component is opposite to the polarity of the magnetic pole of the second magnetic part facing the end of the light guiding component.

[0066] In the embodiment of the present application, the light-guiding component is arranged between the first magnetic part and the second magnetic part, and the magnetic poles of the first magnetic part and the second magnetic part facing the light-guiding component are opposite. By adjusting the distance between the first magnetic part or the second magnetic part and the light-guiding component, the distribution position of the magnetic light-shielding medium can be adjusted, making the adjustment of the distribution position of the magnetic light-shielding medium more convenient.

[0067] In addition, since the magnetic poles of the first magnetic part and the second magnetic part facing the light guiding component are opposite, the first magnetic part and the second magnetic part exert opposite forces on the magnetic light shading medium. By adjusting the distance between the first magnetic part and the light guiding component, and the distance between the second magnetic part and the light guiding component, the first magnetic force of the first magnetic part on the magnetic light shading medium and the second magnetic force of the second magnetic part on the magnetic light shading medium can be matched in magnitude and in opposite directions. Therefore, under the action of the first magnetic force and the second magnetic force, the position of the magnetic light shading medium can be maintained unchanged, and the position of the magnetic light shading medium can be maintained unchanged even when the electronic device is in motion, thereby stabilizing the imaging effect of the electronic device and enhancing the use effect of the electronic device.

[0068] As an optional embodiment, the first magnetic part and the second magnetic part are both electromagnets. In this way, by controlling the intensity of the current flowing through the electromagnet, the magnitude of the magnetic force between the first magnetic part and the second magnetic part can be controlled, which makes the adjustment of the magnetic force between the first magnetic part and the second magnetic part more convenient and flexible.

[0069] As an optional implementation, the magnetic component includes at least two magnetic parts which are sequentially stacked, and the magnetic forces of at least some of the at least two magnetic parts are different.

[0070] In the implementation manner of the present application, since the magnetic forces of at least some of the at least two magnetic parts are different and the strength of the magnetic force of each magnetic part can be controlled individually, the flexibility and diversity of the method of adjusting the distribution position of the magnetic shading medium can be further enhanced.

[0071] In addition, since the magnetic component is composed of multiple magnetic parts stacked together, when some of the magnetic parts fail, only the failed magnetic parts need to be replaced instead of replacing all the magnetic parts, which reduces maintenance costs.

[0072] See also Figure 3 , Figure 3 A flowchart of a method for manufacturing a periscope lens assembly provided in an embodiment of the present application, such as Figure 3 As shown, the method for manufacturing a periscope lens assembly comprises the following steps:

[0073] Step 301, obtaining a light-transmitting substrate, a light-shielding medium and a light transmission component;

[0074] The specific material of the light-transmitting substrate is not limited here, and the material of the light-transmitting substrate can be plastic or the like.

[0075] Optionally, the shape of the light-transmitting substrate can match the shape of the light-transmitting component, so that the light-guiding component obtained by the light-transmitting substrate can be better fixedly connected to the light-transmitting component and the diffraction phenomenon of the incident light beam can be better reduced.

[0076] Step 302, disposing the light-shielding medium at the edge of the light incident surface of the first end of the light-transmitting substrate to obtain a light-guiding component;

[0077] Among them, a light-shielding medium is set at the edge position of the light incident surface of the first end of the light-transmitting substrate to obtain a light-guiding component. Specifically, the light-shielding medium is applied to the above-mentioned edge position, and the distribution density of the light-shielding medium at the edge position is adjusted, and then the light-shielding medium is fixed to the edge position of the light incident surface by glue.

[0078] After obtaining the light-transmitting substrate, the light-transmitting substrate may be pre-processed so that the shape of the light-transmitting substrate matches the shape of the light transmission component.

[0079] Step 303: fixedly connect the light guide component and the light transmission component to obtain the periscope lens assembly.

[0080] In the implementation mode of the present application, since a shading medium is provided at the edge position of the light incident surface of the light guiding component of the final periscope lens assembly, when the incident light beam is irradiated from the light incident surface into the light guiding component, the shading medium can optimize the light field distribution of the incident light beam, thereby reducing the noise and edge oscillation of the diffraction pattern, weakening the diffraction order energy of the incident light beam, reducing the interference of the diffracted light on the image finally formed by the periscope lens assembly, and thereby enhancing the imaging effect of the image finally formed by the periscope lens assembly.

[0081] As an optional implementation, see Figure 3 The light-shielding medium 11 is a magnetic light-shielding medium, and the light-shielding medium is arranged at the edge of the light-incident surface of the first end of the light-transmitting substrate to obtain a light-guiding component, including:

[0082] Applying the magnetic light-shielding medium to the edge of the light incident surface of the first end of the light-transmitting substrate 100 to obtain the light-guiding component 10;

[0083] Obtain an annular magnetic member or two semi-annular magnetic members 200, and sleeve the annular magnetic member or the two semi-annular magnetic members 200 onto the light guide member 10;

[0084] By means of the magnetic force exerted by the annular magnetic part or the two semi-annular magnetic parts 200 on the magnetic light-shielding medium, the distribution position of the magnetic light-shielding medium at the edge position of the light incident surface of the light-guiding component 10 is adjusted so that the distribution density of the light-shielding medium 11 close to the center of the light incident surface is smaller than the distribution density of the light-shielding medium 11 far from the center of the light incident surface.

[0085] The magnetic light-shielding medium of the embodiment of the present application may also be referred to as magnetic powder.

[0086] In the embodiment of the present application, the distribution position of the magnetic light-shielding medium at the edge position of the light incident surface of the light-guiding component 10 can be adjusted by an annular magnetic part or two semi-annular magnetic parts 200, so that the distribution density of the light-shielding medium 11 close to the center of the light incident surface is smaller than the distribution density of the light-shielding medium 11 far from the center of the light incident surface, that is, the distribution density of the light-shielding medium 11 close to the center of the light incident surface is small, while the distribution density of the light-shielding medium 11 far from the center of the light incident surface (i.e., close to the edge position) is large, thereby enabling the final imaging effect of the periscope lens assembly to be better.

[0087] As an optional implementation, see Figure 4 The light-shielding medium 11 is a magnetic light-shielding medium, and the light-shielding medium is arranged at the edge of the light-incident surface of the first end of the light-transmitting substrate to obtain a light-guiding component, including:

[0088] The magnetic light-shielding medium is applied to the edge of the light incident surface of the first end of the light-transmitting substrate to obtain the light-guiding component, wherein the magnetic light-shielding medium forms an annular light-shielding area, and the light-transmitting area of ​​the light incident surface is located within the annular light-shielding area;

[0089] Obtain two first magnetic members 300 , and dispose the light guide member 10 between the two first magnetic members 300 ;

[0090] Rotate the light-guiding component 10, and adjust the distribution position of the magnetic light-shielding medium in the annular light-shielding area through the magnetic force of the two first magnetic parts 300 on the magnetic light-shielding medium, so that the distribution density of the light-shielding medium 11 close to the center of the light-incident surface is smaller than the distribution density of the light-shielding medium 11 far from the center of the light-incident surface.

[0091] The specific shape of the first magnetic member 300 is not limited herein. Optionally, the first magnetic member 300 may be a circular magnetic member or a square magnetic member.

[0092] In the embodiment of the present application, the distribution position of the magnetic light-shielding medium in the annular light-shielding area can also be adjusted by rotating the light-guiding component 10, thus increasing the flexibility and diversity of the methods for adjusting the distribution position of the magnetic light-shielding medium in the annular light-shielding area.

[0093] As an optional implementation, see Figure 5 The light-shielding medium 11 is a magnetic light-shielding medium, the light-transmitting substrate 100 includes a plurality of first regions 12 arranged at intervals, and a second region 13 is provided between any two of the first regions 12. The light-shielding medium is provided at the edge of the light incident surface of the first end of the light-transmitting substrate to obtain a light-guiding component, including:

[0094] Applying the magnetic light-shielding medium to the second region 13 of the light-transmitting substrate 100;

[0095] Obtain a second magnetic member 400, and place the second magnetic member 400 toward the second area 13;

[0096] By means of the magnetic force of the second magnetic member 400 on the magnetic shading medium, the distribution position of the magnetic shading medium in the second area 13 is adjusted so that the distribution density of the shading medium close to the first area 12 is smaller than the distribution density of the shading medium far from the first area 12;

[0097] Cutting is performed in the second region 13 to obtain the light guide component 10, wherein the light guide component 10 includes the first region 12 and at least part of two second regions 13 adjacent to the first region 12. For details, see Figure 6 .

[0098] The cutting in the second area 13 may be performed by using a technique such as laser cutting, thereby obtaining a plurality of light guide components 10 .

[0099] The first region 12 may be referred to as a sample region, and two adjacent first regions 12 may be referred to as a sample1 region and a sample2 region, respectively.

[0100] Among them, see Figure 5 A light shielding medium 11 may be disposed on both the light incident surface 101 and the light emitting surface 102 of the light-transmitting substrate 100 .

[0101] In the implementation manner of the present application, the flexibility and diversity of the method for adjusting the distribution position of the magnetic light-shielding medium in the annular light-shielding area are also increased.

[0102] As an optional implementation, see Figure 7 The second magnetic member 400 includes at least two magnetic parts 401 which are sequentially stacked, and the magnetic forces of at least some of the at least two magnetic parts 401 are different.

[0103] In order to achieve different magnetic forces of different magnetic parts 401 , the magnetic forces of the magnetic parts 401 can be adjusted by controlling the number of coil turns, the current, the distance to the light-transmitting substrate 100 , etc. on the magnetic parts 401 .

[0104] In the implementation manner of the present application, since the magnetic forces of at least some of the at least two magnetic parts are different and the strength of the magnetic force of each magnetic part can be controlled individually, the flexibility and diversity of the methods for adjusting the distribution position of the magnetic shading medium in the annular shading area can be further enhanced.

[0105] It should be noted that Figure 3 and Figure 4 ① to ④ in the Figure 5 and Figure 7 ① to ⑥ within the text can be used to indicate the numbers of the production steps.

[0106] It should be noted that, in an optional embodiment, the first magnetic member and the second magnetic member may be electromagnets or permanent magnets.
