DETAILED DESCRIPTION

[0055] As described in the background technology, the lens assembly is an important component of the shooting equipment and is widely used in the fields of cameras, monitors, and the automotive industry. For example, the shooting equipment can be set as a car, and the lens assembly is set on the main body of the car to obtain the scene environment of the main body of the car through the lens assembly; with the improvement of the level of automobile automation, 8 to 12 lens assemblies will be installed on future vehicles, and most of the lens assemblies are located outside the car body, which are easily affected by the environment and contaminated by ice, snow, dust and other dirt, so the cleaning of the lens assembly is becoming more and more important. And a core component in the cleaning of the lens assembly is the injection port that sprays the cleaning fluid to the entire lens, and the injection port is usually set outside the main body of the lens assembly.

[0056] However, since the lens assembly is usually set on the outside of the car body, the lens assembly is easily contaminated with impurities such as ice, snow and dust, which affects the clarity of the image taken by the lens assembly. The jet nozzle has a small spray angle and a high height. It needs to be placed far away from the lens to spray the entire lens and not affect the lens imaging. Therefore, the jet nozzle occupies a large area and has an obviously unsightly appearance. In addition, the design position of the jet nozzle is far away from the lens. After being sprayed, the cleaning fluid needs to fly a distance to reach the desired cleaning area, which wastes energy and needs to be matched with a cleaning device with stronger spraying ability.

[0057] In order to solve the above technical problems, the embodiments of the present application provide a lens assembly and a shooting device, wherein the lens assembly includes a main body, a lens and a cleaning structure; when the lens of the lens assembly is contaminated with impurities such as ice, snow and dust, a cleaning fluid can be sprayed toward the lens through the spray port of the cleaning structure, so that the cleaning fluid can flow through the lens in a first direction, so as to remove impurities such as ice, snow and dust on the surface of the lens by using the cleaning fluid;

[0058] The cleaning structure is concealedly installed on the outer edge of the main body to make the structure of the lens assembly more compact, reduce the assembly space required for the lens assembly, improve the aesthetics of the lens assembly, and reduce the difficulty of installing the lens assembly; and the cleaning structure is concealedly installed on the outer edge of the main body, which can also reduce the distance between the injection port and the lens, and improve the cleaning effect of the cleaning structure on the lens.

[0059] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0060] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0061] Reference Figure 1-Figure 4 The embodiment of the present application provides a lens assembly, including a main body 100, a lens 200 and a cleaning structure 300; wherein the main body 100 can be used to be installed on a car main body 400, etc., the lens 200 and the cleaning structure 300 are both arranged on the main body 100, and the lens 200 and the cleaning structure 300 are arranged along a first direction (i.e., the x direction in the figure), and the first direction can be parallel to the horizontal direction, or the first direction can also form an angle with the horizontal direction;

[0062] Reference Figure 2-Figure 6 Exemplarily, the cleaning structure 300 is provided with a spray port 310 for spraying a cleaning fluid toward a first direction, and the spray port 310 is toward the surface of the lens 200 away from the main body 100, so as to remove impurities such as ice, snow and dust on the surface of the lens 200 through the cleaning fluid.

[0063] In some possible embodiments, the cleaning structure 300 can be concealedly installed on the edge of the main body 100. For example, the cleaning structure 300 can be set on the inner side of the main body 100, and the main body 100 can be set to one of a square body 100, a circular body 100, a teardrop-shaped body 100 and an elliptical body 100.

[0064] It is easy to understand that, along the thickness direction of the main body 100, the orthographic projection of the cleaning structure 300 on the plane where the main body 100 is located can be set on the inner side of the main body 100 to make the structure of the lens assembly more compact and reduce the assembly space required for the lens assembly.

[0065] Exemplarily, a gap may be formed between the edge of the cleaning structure 300 and the outer edge of the main body 100, that is, the main body 100 is arranged around the outside of the cleaning structure 300, so that the cleaning structure 300 is fixed by the main body 100, so that the connection between the cleaning structure 300 and the main body 100 is more stable; the cleaning structure 300 may also be integrally arranged on the main body 100, and a part of the main body 100 forms a spray port 310, so as to clean the lens 200 installed on the main body 100 through the spray port 310.

[0066] When the main body 100 is set as a square main body 100, the cleaning structure 300 can be set at the corners of the square main body 100, and the injection port 310 of the cleaning structure 300 is toward the center of the square main body 100; when the main body 100 is set as a teardrop-shaped main body 100, the cleaning structure 300 can be set at the tip of the teardrop-shaped main body 100, so that the cleaning structure 300 can be hidden and installed on the inner side of the main body 100, making the structure of the lens assembly more compact.

[0067] Alternatively, at least a portion of the cleaning structure 300 is embedded in the main body 100, and the outer edge of the cleaning structure 300 is smoothly transitioned to the outer edge of the main body 100. The main body 100 is formed with an inner recess, and the cleaning structure 300 is filled in the inner recess so that the cleaning structure 300 can be connected to the main body 100, and at least a portion of the cleaning structure 300 can be used to form the outer edge of the lens assembly, so that the cleaning structure 300 can be hiddenly installed on the outer edge of the main body 100.

[0068] Reference Figure 5-Figure 10 In some possible embodiments, the main body 100 may be provided with a receiving groove 110, which accommodates the lens 200, and the bottom surface of the receiving groove 110 is in contact with the first surface of the lens 200, so that the lens 200 can be installed on the main body 100 through the receiving groove 110; illustratively, when the main body 100 is formed with an inner recess, the inner recess can be connected to the receiving groove 110, so that the lens 200 can be fixed by cooperating with the cleaning structure 300 and the main body.

[0069] The main body 100 may also be provided with an abutment portion 120, at least part of which is provided in the receiving groove 110, and the abutment portion 120 abuts against the second surface of the lens 200, so that the bottom surface of the receiving groove 110 and the abutment portion 120 abut against the first surface and the second surface of the lens 200 respectively, thereby making the installation of the lens 200 more stable through the abutment portion 120.

[0070] It should be noted that the abutment portion 120 can be set as an annular abutment portion 120, the outer side of the annular abutment portion 120 is connected to the main body 100, and the inner side of the annular abutment portion 120 extends toward the center of the receiving groove 110, so that the abutment portion 120 faces the surface of the bottom surface of the receiving groove 110 and abuts against the second surface of the lens 200; or, the abutment portion 120 can also be set as a block-shaped abutment portion 120, the first end of the block-shaped abutment portion 120 is connected to the main body 100, and the second end of the block-shaped abutment portion 120 extends toward the center of the receiving groove 110, so that the abutment portion 120 faces the surface of the bottom surface of the receiving groove 110 and abuts against the second surface of the lens 200.

[0071] The material of the abutment portion 120 can be set to a flexible material. When the lens 200 needs to be installed in the receiving groove 110, the lens 200 is moved in the vertical direction so that the abutment portion 120 is deformed, and the first surface of the lens 200 abuts against the bottom surface of the receiving groove 110, and the abutment portion 120 returns to its original state, so that the abutment portion 120 abuts against the second surface of the lens 200, thereby realizing the installation process of the lens 200.

[0072] Exemplarily, the lens 200 can be set as a square lens 200 or a circular lens 200. For example, the lens 200 is set as a circular lens 200. In the first direction, the center of the circular lens 200 is correspondingly arranged at the center of the injection port 310 along the second direction to increase the area of ​​the cleaning fluid flowing through the second surface of the circular lens 200; the second surface of the circular lens 200 is protruded away from the main body 100, and the second surface of the circular lens 200 at least partially extends out of the accommodating groove 110 to increase the visible range 210 of the circular lens 200 and improve the shooting effect of the lens assembly.

[0073] In some possible embodiments, the cleaning structure 300 is configured as: 0.1≤(Dd) / 2L≤1; wherein L is configured as the distance between the jet port 310 and the center of the lens 200; d is configured as the length of the jet port 310 in the second direction (i.e., the y direction in the figure), and D is configured as the length of the lens 200 in the second direction.

[0074] Exemplarily, the cleaning structure 300 can be configured as: (Dd) / 2L≤0.5. For example, (Dd) / 2L can be set to one of 0.1, 0.2, 0.3, 0.4 and 0.5, so that the cleaning fluid sprayed from the injection port 310 of the cleaning structure 300 can fully flow through the surface of the lens 200, thereby improving the cleaning effect of the lens 200.

[0075] In the second direction, the length of the jet port 310 is greater than or equal to half the length of the lens 200, that is, d / D ≥ 50%, and the second direction is perpendicular to the first direction. For example, the length of the jet port 310 can be set to one of 50%, 60%, 70%, 80%, 90% and 100% of the length of the lens 200 to increase the width of the cleaning fluid sprayed by the jet port 310.

[0076] By adopting the above technical solution, when the second surface of the lens 200 of the lens assembly is contaminated with impurities such as ice, snow, and dust, the cleaning structure 300 sprays the cleaning fluid along the first direction through the injection port 310, and the width of the cleaning fluid in the second direction is greater than half of the length of the lens 200 in the second direction, thereby increasing the area of ​​the lens 200 surface through which the cleaning fluid flows, and reducing the area of ​​the lens 200 through which the cleaning fluid does not flow, so as to remove impurities such as ice, snow, and dust on the second surface of the lens 200 through the cleaning fluid.

[0077] It should be noted that, in the second direction, the length of the injection port 310 is greater than or equal to half the length of the lens 200; for example, when the lens 200 is set as a circular lens 200, the length of the circular lens 200 in the second direction is equal to the diameter of the circular lens 200, that is, in the second direction, the length of the injection port 310 is greater than or equal to half the diameter of the circular lens 200;

[0078] When the lens 200 is set as a circular lens 200, in the plane where the first direction and the second direction are located, the jet port 310 can be set as an arc-shaped jet port 310, or the jet port 310 can also be set as a rectangular jet port 310. The embodiment of the present application does not impose further restrictions on this, as long as it can be ensured that the jet port 310 is facing the center of the circular lens 200 to increase the area of ​​the cleaning fluid flowing through the surface of the lens 200.

[0079] Reference Figure 5 and Figure 6 Exemplarily, at least a portion of the cleaning structure 300 is embedded in the main body 100, and the outer edge of the cleaning structure 300 smoothly transitions to the outer edge of the main body 100. The cleaning structure 300 can be movably set on the main body 100. The main body 100 is provided with a pressure ring 140, and at least a portion of the pressure ring 140 abuts against the second surface of the lens 200. The surface of the pressure ring 140 facing away from the main body 100 is attached to the cleaning structure 300, so as to separate the cleaning structure 300 from the main body 100 through the pressure ring 140.

[0080] It is easy to understand that, by movably disposing the cleaning structure 300 on the main body 100 , the cleaning structure 300 can be installed on main bodies 100 of different specifications, so that the cleaning structure 300 has a wider application range.

[0081] Exemplarily, a portion of the pressing ring 140 forms the abutting portion 120 , so that the pressing ring 140 abuts against the second surface of the lens 200 , so that the pressing ring 140 can fix the lens 200 together with the bottom surface of the receiving groove 110 .

[0082] Exemplarily, the main body 100 may be provided with a mounting portion 130, the mounting portion 130 is used to be mounted on a car body 400, etc., and the mounting portion 130 and the lens 200 are arranged along the thickness direction of the main body 100. When the mounting portion 130 is installed on the car body 400, the mounting portion 130 is embedded inside the car body 400, and the part of the main body 100 where the receiving groove 110 is arranged is arranged outside the car body 400, so that the lens 200 and the cleaning structure 300 can be relatively fixed to the car body 400 through the main body 100;

[0083] The cleaning structure 300 is provided with a guide channel 340, the first end of which is used to connect to a storage device for storing cleaning fluid, and the first end of the guide channel 340 is arranged on the inner side of the automobile body 400; the second end of the guide channel 340 extends to the outer side of the automobile body 400, and the second end of the guide channel 340 forms a spray port 310 so that the storage device provides cleaning fluid to the spray port 310 through the guide channel 340.

[0084] Or, refer to Figure 7 and Figure 8 Along the thickness direction of the main body 100, the orthographic projection of the cleaning structure 300 on the plane where the main body 100 is located can be set on the inner side of the main body 100. The cleaning structure 300 can also be integrally set on the main body 100. At least part of the cleaning structure 300 abuts against the second surface of the lens 200, making the structure of the lens assembly more compact and reducing the assembly space required for the lens assembly.

[0085] Exemplarily, part of the cleaning structure 300 can be used to form the abutment portion 120, so that the lens 200 can be relatively fixed to the main body 100 through the cleaning structure 300, making the functionality of the cleaning structure 300 more abundant; and the cleaning structure 300 is integrally arranged on the main body 100, making the molding process of the main body 100 and the cleaning structure 300 more convenient, reducing the assembly process between the main body 100 and the cleaning structure 300, and reducing the production cost of the lens assembly.

[0086] Reference Fig. 9 and Fig.10 In some possible embodiments, the second surface of the circular lens 200 is protruded away from the main body 100, and the second surface of the circular lens 200 at least partially extends out of the accommodating groove 110; the cleaning structure 300 is arranged outside the visible range 210 of the circular lens 200 to reduce the influence of the cleaning structure 300 on the visible range 210 of the circular lens 200.

[0087] It should be noted that the angle of the visible range 210 of the circular lens 200 can be set to V, the visible range 210 of the circular lens 200 can be determined according to the shape of the second surface of the circular lens 200, and the visible range 210 of the circular lens 200 is symmetrically arranged relative to the central axis of the circular lens 200, and the edge of the visible range 210 of the circular lens 200 forms a certain angle with the central axis of the circular lens 200;

[0088] By setting the cleaning structure 300 outside the visible range 210 of the circular lens 200, that is, the angle between the cleaning structure 300 and the central axis of the circular lens 200 is greater than the angle between the edge of the visible range 210 and the central axis of the circular lens 200, the cleaning structure 300 will not block the lens 200, thereby ensuring the use effect of the lens 200.

[0089] It is easy to understand that the lower the height of the cleaning structure 300 extending out of the main body 100, the smaller the possibility that the cleaning structure 300 is located in the visible range 210 of the circular lens 200; the farther the cleaning structure 300 is from the circular lens 200 in the first direction, the smaller the possibility that the cleaning structure 300 is located in the visible range 210 of the circular lens 200. Therefore, the cleaning structure 300 can be located outside the visible range 210 of the circular lens 200 by adjusting the height of the cleaning structure 300 extending out of the main body 100 and the distance between the cleaning structure 300 and the circular lens 200 in the first direction.

[0090] Exemplarily, in the first direction, the jet port 310 is spaced apart from the lens 200, and the distance between the jet port 310 and the lens 200 can be set to L, and the distance L between the jet port 310 and the lens 200 is greater than or equal to 2 mm and less than or equal to 20 mm; for example, the distance between the jet port 310 and the lens 200 can be set to one of 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, 16 mm, 18 mm and 20 mm, thereby reducing the possibility of the cleaning structure being located within the visible range 210.

[0091] It should be noted that when the cleaning structure 300 is farther away from the circular lens 200 in the first direction, the length of the lens assembly in the first direction is longer, so that the occupied area of ​​the lens assembly is larger and the overall aesthetics of the lens assembly is lower;

[0092] Moreover, when the distance between the cleaning structure 300 and the circular lens 200 in the first direction is farther, the distance between the injection port 310 of the cleaning structure 300 and the circular lens 200 in the first direction is farther, so that the energy required for the cleaning fluid sprayed from the injection port 310 to flow to the circular lens 200 is greater, thereby affecting the cleaning effect of the cleaning fluid on the second surface of the circular lens 200.

[0093] By setting the distance between the jet port 310 and the lens 200 to be greater than or equal to 2 mm and less than or equal to 20 mm, the possibility of the cleaning structure being within the visible range 210 is reduced, and the distance between the cleaning structure 300 and the circular lens 200 can be reduced, thereby improving the overall aesthetics of the lens assembly and reducing the energy required for the cleaning fluid sprayed from the jet port 310 to flow to the circular lens 200.

[0094] Reference Figure 5 and Figure 6 In some possible implementations, the lens assembly can be configured as: 0.1≤h / H≤6; wherein, h can be configured as the height of the jet port 310 in the thickness direction of the lens 200, and H can be configured as the distance between the center of the second surface of the lens 200 and the bottom end of the jet port 310, so that the cleaning fluid sprayed from the jet port 310 can fully flow on the second surface of the lens 200, thereby improving the cleaning effect of the cleaning fluid on the second surface of the lens 200.

[0095] Exemplarily, in the thickness direction of the lens 200, a height difference is set between the bottom end of the injection port 310 and the second surface of the lens 200, and the lens assembly is configured as: 0.1 mm ≤ h / (H×X) ≤ 6 mm; wherein X is configured as the height difference between the bottom end of the injection port 310 and the second surface of the lens 200.

[0096] For example, the value of h / (H×X) can be configured to be one of 0.1 mm, 0.2 mm, 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm and 6 mm so that the injection port 310 does not affect the visible range 210 and the structure of the lens assembly is more compact.

[0097] It should be noted that the second surface of the circular lens 200 is convexly arranged away from the main body 100. When the extension height of the injection port 310 is relatively high, the cleaning fluid sprayed from the injection port 310 is easy to flow over the second surface of the circular lens 200, affecting the cleaning effect of the cleaning fluid on the second surface of the circular lens 200.

[0098] By setting the extension height of the jet port 310 to be less than or equal to 0.05 times the distance between the center of the second surface of the circular lens 200 and the bottom end of the jet port 310, the jet port 310 can spray the cleaning fluid toward the second surface of the circular lens 200, so that the cleaning fluid can satisfy the Coandal effect. In a first direction, the cleaning fluid can flow from the part of the circular lens 200 toward the jet port 310 to the part of the circular lens 200 away from the jet port 310, so that the second surface of the circular lens 200 can be cleaned by the cleaning fluid.

[0099] Exemplarily, the height of the injection port 310 may be set to h, the length of the injection port 310 in the second direction may be set to d, and the height of the injection port 310 may be less than or equal to 0.12 times the length of the injection port 310 in the second direction, that is, h / d≤0.12;

[0100] For example, the ratio of the height of the injection port 310 to the length of the injection port 310 in the second direction can be set to one of 0.02, 0.04, 0.06, 0.08, 0.10 and 0.12, so that the cleaning fluid can be uniformly sprayed from the injection port 310 in the second direction, so that the flow rate of the cleaning fluid sprayed from the injection port 310 at various locations along the second direction is more uniform, so that the cleaning fluid can flow uniformly on the second surface of the circular mirror along the first direction.

[0101] Moreover, the height of the injection port 310 is less than or equal to 0.12 times the length of the injection port 310 in the second direction, which reduces the extension height of the injection port 310, so that the cleaning fluid can satisfy the Coandal effect and reduce the possibility of the cleaning fluid flowing over the second surface of the circular lens 200.

[0102] Reference Fig.11 and Fig.12 In some possible embodiments, the cleaning structure 300 is further provided with a baffle 320, which extends along the second direction; the first end of the baffle 320 is connected to the cleaning structure 300, and the first end of the baffle 320 is connected to the top of the injection port 310, and the second end of the baffle 320 extends toward the lens 200, so as to shield the cleaning fluid sprayed from the injection port 310 through the baffle 320 to a certain extent, so that the cleaning fluid can flow along the first direction toward the second surface of the circular lens 200.

[0103] Exemplarily, in the first direction, the length of the baffle 320 can be smaller than the distance between the injection port 310 and the circular lens 200 to reduce the possibility that the baffle 320 is located within the visible range 210 of the circular lens 200; alternatively, the length of the baffle 320 can also be adjusted according to the visible range 210 of the circular lens 200, and the embodiments of the present application do not impose further restrictions on this.

[0104] Reference Figure 2-Figure 6 In some possible embodiments, the cleaning structure 300 is further provided with a guide member, a first end of the guide member is connected to the injection port 310, and a second end of the guide member faces the circular lens 200. The width of the guide member gradually increases from the first end of the guide member to the second end of the guide member, so as to increase the flow angle of the cleaning fluid through the guide member and increase the flow area of ​​the cleaning fluid on the second surface of the circular lens 200.

[0105] Exemplarily, the guide member includes two guide parts 330, both of which are disposed on the main body 100, and the two guide parts 330 are symmetrically disposed relative to the first direction; the ends of the two guide parts 330 close to the injection port 310 form the first end of the guide member, and the ends of the two guide parts 330 close to the circular lens 200 form the second end of the guide member; for example, referring to Figure 3 and Figure 4 In a plane parallel to the first direction and the second direction, the guide portion 330 can be arranged tangent to the circular lens 200 so that the cleaning fluid sprayed from the injection port 310 can flow to the edge of the circular lens 200 through the guide portion 330, thereby increasing the flow area of ​​the cleaning fluid on the second surface of the circular lens 200.

[0106] Reference Figure 2-Figure 4 The guide portion 330 forms an angle with the first direction, and the angle is greater than or equal to 10 degrees and less than or equal to 60 degrees; for example, the angle can be set to one of 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees and 60 degrees.

[0107] Exemplarily, the guide portion 330 can be integrally provided in the cleaning structure 300, or the guide portion 330 can also be installed in the cleaning structure 300 by bonding or the like; or, part of the main body 100 can also be used to form the guide portion 330, so that the guide portion 330 can be integrally provided with the main body, making the molding process of the guide portion 330 more convenient.

[0108] In some possible implementations, the lens assembly may be configured as one of a first lens assembly, a second lens assembly, a third lens assembly, and a fourth lens assembly, wherein the first lens assembly is configured as Figure 7 and Figure 8 As shown, the second lens assembly is as follows Fig.11 and Fig.12 As shown, the third lens assembly is as follows Figure 3 As shown, the fourth lens assembly is as follows Fig. 9 and Fig.10 shown.

[0109] Table 1 is a schematic diagram of the dimensions of the first lens assembly, the second lens assembly, the third lens assembly and the fourth lens assembly, wherein the units of d, D, h, X, L and H are all set to millimeters.

[0111] Table 1

[0112] As shown in Table 1, d / D is greater than 0.5, h / d is less than 0.12, (Dd) / 2L is greater than 0.1 and less than 1, and h / (H×X) is greater than 0.1 mm and less than 6 mm, thereby increasing the width of the cleaning fluid sprayed from the injection port 310 and increasing the area of ​​the cleaning fluid flowing through the surface of the lens 200.

[0113] In summary, when the lens 200 of the lens assembly is contaminated with impurities such as ice, snow, and dust, the cleaning fluid can be sprayed toward the lens 200 along the first direction through the spray port 310 of the cleaning structure 300, so that the cleaning fluid can flow through the lens 200 along the first direction, so as to remove the impurities such as ice, snow, and dust on the surface of the lens 200 by using the cleaning fluid;

[0114] The cleaning structure 300 is concealedly installed on the outer edge of the main body 100 to make the structure of the lens assembly more compact, reduce the assembly space required for the lens assembly, improve the aesthetics of the lens assembly, and reduce the difficulty of installing the lens assembly; and the cleaning structure 300 is concealedly installed on the outer edge of the main body 100, which can also reduce the distance between the injection port 310 and the lens 200, thereby improving the cleaning effect of the cleaning structure on the lens.
