Camera module and vehicle{CAMERA MODULE AND VEHICLE}

The present invention relates to camera modules and vehicles.

Recently, ultra-small camera modules have been developed, and ultra-small camera modules are widely used in small electronic products such as smartphones, laptops, and game consoles.

As automobiles become more popular, ultra-small cameras are widely used not only in small electronic products but also in vehicles. For example, a black box camera for vehicle protection or objective data on traffic accidents, a rear surveillance camera that allows the driver to monitor blind spots at the rear of the vehicle through the screen to ensure safety when the vehicle is reversing, It is equipped with a surrounding detection camera that can monitor the surroundings of the vehicle.

A camera may be provided with a lens, a lens holder that accommodates the lens, an image sensor that converts an image of a subject collected in the lens into an electrical signal, and a printed circuit board on which the image sensor is mounted. The housing that forms the exterior of the camera has an entirely sealed structure to prevent internal components from being contaminated by foreign substances containing moisture.

As described above, the camera module 10 according to an embodiment of the present invention includes the lens module 300 and the second body 100 through the first guide 130 and the second guide 330. can be combined with each other.

As shown in FIG. 8, before coupling the lens module 300, the sealing member 600 may be coupled to the upper surface of the barrel portion 120. The sealing member 600 may be formed by coupling a ring-shaped member of hardened epoxy to the groove 150. Alternatively, the sealing member 600 may be formed by applying liquid epoxy to the groove 150 through post-processing. It can be hardened.

Next, the lens module 300 may be coupled to the barrel portion 120. At this time, as shown in FIG. 9, when the lens module 300 is coupled to the first body 100, the third protrusion 332 is connected to the barrel portion ( The lens module 300 may be moved in the optical axis direction so as to contact the upper surface of 120.

Next, as shown in FIG. 10, the lens module 300 can be rotated clockwise or counterclockwise so that the third protrusion 332 is coupled to the coupling groove 136. Accordingly, as shown in FIG. 11, the third protrusion 332 is disposed between the second protrusion 134 and the upper surface of the barrel portion 120, so that the first body 100 and the lens module ( 300) can be firmly maintained.

To improve coupling strength, adhesive may be applied between the third protrusion 332 and the inner surface of the coupling groove 136.

Meanwhile, when the third protrusion 332 is coupled to the coupling groove 136, at least a portion of the third protrusion 332 may protrude outward from the outer surface of the barrel portion 120.

According to the above structure, there is an advantage of easy assembly and improved production efficiency due to the coupling structure between the lens module and the first body through the first guide and the second guide.

In particular, compared to the conventional structure in which the lens module and the first body are screwed together, there is an advantage in preventing the generation of foreign substances during the assembly process and preventing failures such as malfunction of components within the module.

Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features. You will be able to understand it. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive.
