Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of camera modules, in particular to an anti-dew substrate lens assembly and a camera module. Background Art
[0002] As people's demand for driving safety continues to increase, camera modules have become an indispensable part of automobiles. At present, after the camera module is assembled on the car body, part of the appearance of the camera module can be seen through the holes in the car body. If this part of the appearance appears in other colors besides the color of the surface protective layer of the lens, it will affect the overall appearance of the car and reduce the beauty of the car. The surface protective layer on the surface of the camera module is usually an insulating layer, which will isolate the conduction between the lens and the shell, thereby affecting the electromagnetic compatibility (EMC) of the camera module. In order to take into account the electromagnetic compatibility of the camera module, the surface protective layer of the lower surface of the lens and the upper surface of the shell is usually removed so that the lens and the shell are mutually conductive. Since the lens and the shell themselves have a certain assembly tolerance, if the surface protective layer is directly removed on the upper surface of the shell, the base material of the shell will exceed the lens, thereby affecting the appearance. And because the surface protective layer has a certain thickness, if only a part of the surface protective layer on the upper surface of the shell is removed, it is difficult for the lens to fit with the shell, and thus it cannot be conductive. Utility Model Content
[0003] Based on this, it is necessary to provide an anti-dew substrate lens assembly and a camera module to address the problem that after the surface protective layer of the shell of the existing camera module is removed, the exposed substrate exceeds the coverage of the lens.
[0004] A dew-proof substrate lens assembly, comprising:
[0005] A lens, the lens comprising a lens barrel and a flange portion arranged around the lens barrel, the lens having a lens protection layer, and a lower surface of the flange portion having a first contact surface formed by removing the lens protection layer;
[0006] A main body shell, the main body shell includes a fixed shell fixedly connected to the lens barrel, a mounting portion connected to the fixed shell and an abutment portion protruding from the mounting portion, the mounting portion has a mounting groove for mounting a sealing ring, the size of the abutment portion is smaller than the size of the mounting portion, the projection of the abutment portion along the axial direction of the lens is located within the lower surface of the flange portion, the main body shell has a shell protective layer, the upper surface of the abutment portion has a second contact surface formed by removing the shell protective layer, the second contact surface of the abutment portion abuts against the first contact surface of the flange portion, and is used to conduct the main body shell and the lens.
[0007] In one embodiment, the cross section of the abutting portion is annular, and the outer diameter of the abutting portion is smaller than the outer diameter of the flange portion.
[0008] In one embodiment, the shape of the first contact surface is the same as the shape of the second contact surface.
[0009] In one embodiment, the groove wall of the mounting groove is flush with the inner wall of the abutting portion.
[0010] In one of the embodiments, a fixing groove for fixing a sealing ring is formed on the outer surface of the lens barrel, and the fixing groove is located inside the mounting groove.
[0011] In one embodiment, the lens and the main body shell are both made of metal materials.
[0012] In one embodiment, the lens protection layer is one of an electroplating layer, an anodized layer, a spray paint layer or an electrophoretic layer.
[0013] In one embodiment, the shell protective layer is one of an electroplating layer, an anodized layer, a spray paint layer or an electrophoretic layer.

[0030] For details, please refer to Figures 1 to 4The present application provides an anti-dew substrate lens assembly, which may include a lens 10 and a main body shell 20, wherein the lens 10 includes a lens barrel 11 and a flange portion 12 arranged around the lens barrel 11, the lens 10 has a lens 10 protective layer, and the lower surface of the flange portion 12 has a first contact surface 121 formed by removing the lens 10 protective layer. The main body shell 20 includes a fixed shell body 21 fixedly connected to the lens barrel 11, a mounting portion 22 connected to the fixed shell body 21 and a contact portion 23 protruding from the mounting portion 22, the mounting portion 22 has a mounting groove 221 for mounting a sealing ring, the size of the contact portion 23 is smaller than the size of the mounting portion 22, the projection of the contact portion 23 along the axial direction of the lens 10 is located within the lower surface of the flange portion 12, the main body shell 20 has a shell protective layer, the upper surface of the contact portion 23 has a second contact surface 231 formed by removing the shell protective layer, the second contact surface 231 of the contact portion 23 abuts against the first contact surface 121 of the flange portion 12, and is used to conduct the main body shell 20 and the lens 10.
[0031] It can be understood that the lower surface of the mounting portion 22 can be laser engraved to remove part of the protective layer of the lens 10 to form the first contact surface 121, and the upper surface of the abutting portion 23 can be laser engraved to remove all of the outer shell protective layer to form the second contact surface 231. Since the projection of the abutting portion 23 along the axial direction of the lens 10 is entirely located within the lower surface of the flange portion 12, that is, the second contact surface 231 is fully covered by the flange portion 12, the anti-dew substrate lens assembly can ensure the conduction between the lens 10 and the main shell 20 while avoiding the problem of color difference between the lens 10 and the main shell 20 due to the exposure of the substrate of the main shell 20, thereby improving the aesthetics of the camera module.
[0032] Optionally, the cross-sectional shape of the abutting portion 23 may be various shapes as long as it can be fully covered by the flange portion 12 .
[0033] Preferably, if Figure 3 and Figure 4 As shown, in one embodiment, the cross section of the abutting portion 23 is annular, and the outer diameter of the abutting portion 23 is smaller than the outer diameter of the flange portion 12. In this way, the cross-sectional shape of the abutting portion 23 is more regular, which is convenient for laser engraving to form the first contact surface 121 and the second contact surface 231.
[0034] Preferably, if Figure 3 and Figure 4As shown, in one embodiment, the shape of the first contact surface 121 is the same as the shape of the second contact surface 231. With such a configuration, the first contact surface 121 and the second contact surface 231 fit exactly together, which can prevent the first contact surface 121 or the second contact surface 231 from contacting the housing protective layer or the lens 10 protective layer to form a height difference, resulting in the first contact surface 121 and the second contact surface 231 being unable to conduct; on the other hand, it can prevent the exposed area of the first contact surface 121 or the second contact surface 231 from being too large, resulting in corrosion of the substrate of the lens 10 or the substrate of the main housing 20.
[0035] In particular, if Figure 2 As shown, in one embodiment, the groove wall of the mounting groove 221 is flush with the inner wall of the abutment portion 23. This arrangement can reduce the processing steps of the mounting groove 221, making the mounting groove 221 easier to process and form. In addition, the inner side surface of the abutment portion 23 can be used as a part of the mounting groove 221, thereby reducing the required depth of the mounting groove 221.
[0036] Preferably, if Figure 2 As shown, in one embodiment, the outer surface of the lens barrel 11 is provided with a fixing groove 111 for fixing the sealing ring, and the fixing groove 111 is located in the mounting groove 221. When assembling the lens 10 and the main housing 20, the sealing ring can be fixed in the fixing groove 111 first, and then the lens 10 is fixed to the main housing 20. In this way, not only can the problem of the sealing ring being offset be avoided, but also the assembly efficiency can be improved.
[0037] Optionally, in one embodiment, the lens 10 and the main housing 20 are both made of metal materials, so that the lens 10 and the main housing 20 can be connected, so that the anti-dew substrate lens housing forms a complete electromagnetic shielding cavity to improve the electromagnetic compatibility of the camera module.
[0038] Optionally, in one embodiment, the protective layer of the lens 10 is one of an electroplating layer, an anodizing layer, a spray paint layer or an electrophoretic layer. In other words, the protective layer of the lens 10 can be formed by electroplating, anodizing, spray painting or electrophoresis. In this way, the protective layer of the lens 10 can protect the substrate of the lens 10 from corrosion, so as to increase the service life of the camera module.
[0039] Similarly, in one embodiment, the shell protective layer is one of an electroplating layer, an anodized layer, a spray paint layer or an electrophoretic layer. The shell protective layer can be formed by electroplating, anodizing, spray painting or electrophoresis. In this way, the shell protective layer can protect the base material of the main shell 20 from corrosion, so as to increase the service life of the camera module.
[0040] Preferably, in one embodiment, the outer shell protective layer and the lens 10 protective layer are both black material coatings. In this way, the colors of the main shell 20 and the lens 10 are more in line with the color of the actual vehicle, which can improve the overall appearance of the camera module after being assembled on the actual vehicle.
[0041] Further, the present application provides a camera module, which may include any of the above-mentioned anti-dew substrate lens components and a module body 30. The module body 30 is installed on the anti-dew substrate lens component. The module body 30 may include a circuit board component, which is installed on the main housing 20, and the circuit board component is bonded to the lens 10.
[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
