Description

[Technical Field]

[0001] This embodiment relates to a camera device. [Background technology]

[0002] In recent years, ultra-miniature camera modules have been developed and are widely used in small electronic products such as smartphones, notebooks, game consoles, etc.

[0003] As automobiles become more widespread, miniature cameras are increasingly being used in vehicles as well as in small electronic products. For example, there are black box cameras for protecting vehicles or providing objective information on traffic accidents, rearview cameras that allow drivers to monitor blind spots at the rear of a vehicle through a screen to ensure safety when reversing, and perimeter detection cameras that can monitor the area around a vehicle.

[0004] Meanwhile, with the development of technology, there is a trend towards adopting Lane Keeping Assist Systems (LKAS), which receive video signals of the road ahead while driving, analyze them in real time, and then issue an alarm when it detects lane departure caused by driver inattention or drowsiness at the wheel.

[0005] However, due to differences in vehicle size and windshield angle, a separate coupler or other configuration must be used for each vehicle to optimize the viewing angle of the camera for the lane departure automatic return system, which creates the problem of increased mold costs. Summary of the Invention [Problem to be solved by the invention]

[0006] This embodiment provides a camera device that allows the user to adjust the angle of view within a desired range of directivity angles. [Means for solving the problem]

[0054] The support member 400 may be disposed in a region between the one end 311 of the body 310 of the view angle adjusting member 300 and the locking portion 320. The region between the one end of the body 310 of the view angle adjusting member 300 and the locking portion 320 may be disposed in the second opening 120 of the support portion 150 of the bracket 100.

[0055] The view angle adjusting member 300 may include a locking portion 320. The locking portion 320 may be formed to extend in the outer circumferential direction of the main body 310. The locking portion 320 may be disposed between a region where the threads are formed in the main body 310 and one end of the main body 310. The locking portion 320 may be spaced a predetermined distance from the one end of the main body 310. The locking portion 320 may be spaced apart from the threads 312. The locking portion 320 may be formed in a disk shape. The other surface 322 of the locking portion 320, which comes into contact with the bracket 100, may be formed in a curved shape.

[0056] The locking portion 320 may be disposed between the first and second surfaces of the support portion 150 of the bracket 100.

The other surface 322 of the locking portion 320, which is formed in a curved shape, may contact the inclined surface 130 formed in the second opening 120 of the bracket 100. The radius of curvature of the other surface 322 of the locking portion 320 may correspond to the radius of curvature of the inclined surface 130 of the bracket 100. One surface of the locking portion 320 may be supported by the support member 400. The one surface 321 of the locking portion 320 may contact the protrusion 410 of the support member 400. This may prevent the view angle adjusting member 300 from moving unintentionally due to transmission of external force or vibration. Specifically, one surface of the locking portion 320 is supported by the protrusion 410 of the support member 400, and the other surface 322 of the locking portion 320 can be maintained in contact with the inclined surface 130 of the bracket 100. As a result, even if an external force or vibration is transmitted to the view angle adjusting member 300 in a direction that loosens the bracket 100 and the camera module 200, a force can be applied that pushes the locking portion 320 of the view angle adjusting device 300 toward the support portion 150 of the bracket 100, thereby preventing the connection between the bracket 100 and the camera module from loosening.

[0057] In one embodiment of the present invention, the other side of the view angle adjusting member 300 can be interpreted as meaning the direction in which the camera module 200 is located, and one side can be interpreted as meaning the opposite direction of the other side.
