Abstract
Description
Technical Field
[0001] The utility model relates to the field of vehicle-mounted cameras, and in particular to a packaging structure of a vehicle-mounted camera. Background Art
[0002] As we all know, in-vehicle cameras are essential sensors for modern vehicles and will be increasingly installed in future vehicles. Cameras installed outside the vehicle must possess extremely high self-protection capabilities and maintain normal operation in extreme environments. Currently, in-vehicle cameras on the market have a connecting ring around the lens, which is bonded to the housing with UV adhesive. To increase the adhesion between the lens and the housing, the outer diameter of the connecting ring is generally increased to increase the contact area with the adhesive. However, this results in a larger appearance for the in-vehicle camera, hindering miniaturization. Utility Model Content
[0003] In view of the deficiencies of the prior art, the utility model provides a packaging structure for a vehicle-mounted camera, which is beneficial to increasing the bonding strength of UV glue to the lens and the housing, thereby miniaturizing the camera.
[0004] To achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:
[0005] A packaging structure for a vehicle-mounted camera includes a housing and a lens, wherein one end of the lens is inserted into the housing, and a connecting ring extends outward from the outer surface of the lens, with a plurality of through holes provided on the connecting ring; one end of the housing faces the connecting ring and extends an annular boss toward the connecting ring, with a groove provided on the side of the annular boss; UV glue is applied to the end face of the annular boss, and the UV glue is squeezed between the connecting ring and the annular boss, the UV glue fills the through holes and forms a protrusion blocking the through holes on the side of the connecting ring facing away from the annular boss to form an undercut structure; the UV glue flows through the outer peripheral surface of the annular boss and fills the groove to form the undercut structure.
[0006] Furthermore, the outer diameter of the annular boss is smaller than the outer diameter of the portion of the housing connected to the annular boss, and the outer diameter of the connecting ring is larger than the outer diameter of the annular boss.
[0007] Furthermore, the groove is an annular groove that circles the outer circumference of the annular protrusion, and the UV glue covers the outer circumference of the annular boss.
[0008] Furthermore, there are multiple grooves, and the multiple grooves are evenly distributed along the circumference of the annular boss.
[0009] Furthermore, the connecting ring is provided with a plurality of through holes, and the plurality of through holes are evenly distributed along the circumference of the connecting ring.
[0010] The utility model has the following beneficial effects:
[0011] The vehicle-mounted camera packaging structure provided by the utility model has the following characteristics: after the UV glue solidifies, the UV glue is connected to the connecting ring on the lens through an undercut structure, and the UV glue is connected to the annular boss on the shell through an undercut structure, thereby preventing the lens and the shell from moving backwards, greatly improving the bonding strength of the lens and the shell; in addition, by providing a through hole, the contact area between the UV glue and the lens is increased, and even if the outer diameter of the connecting ring is reduced, the lens and the shell can be firmly connected, thereby reducing the external dimensions of the lens and miniaturizing the vehicle-mounted camera.

[0013] Figure 2 yes Figure 1 A cross-sectional view of a vehicle-mounted camera. DETAILED DESCRIPTION
[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0016] like Figures 1 to 2 As shown, this embodiment discloses a packaging structure of a vehicle-mounted camera, which includes a housing 1 , a lens 2 , a back cover 11 , a coaxial terminal 13 and a circuit board 12 .
[0017] The invention comprises a housing 1 and a lens 2. One end of the lens 2 is inserted into the interior of the housing 1. A connecting ring 3 extends from the outer surface of the lens 2 in all directions and is provided with a plurality of through-holes 4. One end of the housing 1 faces the connecting ring 3 and extends an annular boss 5 toward the connecting ring 3. The side of the annular boss 5 is provided with a groove 6. UV glue is applied to the end face of the annular boss, and the connecting ring and the annular boss squeeze the UV glue. The UV glue fills the through-holes and forms a protrusion blocking the through-hole on the side of the connecting ring facing away from the annular boss, forming an inverted structure. The UV glue flows through the outer circumference of the annular boss and fills the grooves to form an inverted structure. After the UV glue solidifies, the UV glue connects to the connecting ring on the lens through the inverted structure, and the UV glue connects to the annular boss on the housing through the inverted structure, thereby preventing the lens and housing from moving in opposite directions and greatly improving the bonding strength between the lens 2 and the housing 1. In addition, the provision of the through-holes increases the contact area between the UV glue 7 and the lens, thereby reducing the outer diameter of the connecting ring, that is, reducing the overall dimensions of the lens, making the vehicle-mounted camera miniaturized.
[0018] Preferably, the outer diameter of the annular boss 5 is smaller than the outer diameter of the portion of the housing 1 connected to the annular boss 5, and the outer diameter of the connecting ring 3 is larger than the outer diameter of the annular boss 5, thereby restricting the UV glue that has not yet solidified and preventing the glue from flowing freely.
[0019] In this embodiment, the groove 6 is an annular groove 6 that runs around the outer circumference of the annular boss 5. The UV adhesive covers the outer circumference of the annular boss, forming an undercut structure that secures the entire annular boss. The diameter of the ring of UV adhesive 7 within the annular groove 6 is smaller than that of the annular boss 5. Even under vibration, the cured UV adhesive 7 is unlikely to separate from the annular boss 5. The housing 1 may be provided with two or more annular grooves 6, coaxially distributed along the direction in which the lens 2 is inserted into the housing 1, forming a multi-layer undercut structure 9.
[0020] The grooves 6 can also be configured in other shapes, such as arcs or circles. Multiple grooves can be distributed along the outer circumference of the annular boss 5 to form multiple undercut structures 9. Preferably, the grooves are evenly distributed along the outer circumference of the annular boss 5 to prevent the UV adhesive 7 from being disengaged from the housing due to uneven localized force. The cross-sectional shape of the grooves 6 is not limited and can be square, C-shaped, etc.
[0021] In this embodiment, the connecting ring 3 is provided with multiple through-holes, with multiple through-holes 4 distributed along the circumference of the connecting ring 3, thereby forming an undercut structure at multiple points. Preferably, the multiple through-holes are evenly distributed along the circumference of the connecting ring to prevent the UV adhesive 7 from being disengaged from the connecting ring 3 due to uneven localized force, resulting in a poor seal. The shape of the through-holes 4 is not limited to circular; various shapes such as polygonal and arcuate are also acceptable. The number of through-holes is not limited and can be one or more.
[0022] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate from the spirit and scope of the technical solutions of the embodiments of the present invention. Therefore, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present invention.
