Description

[Technical field]

[0001] The present invention 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, ultra-small cameras are being used not only in small electronic products but also in vehicles. For example, black box cameras for vehicle protection or objective data on traffic accidents, rear monitoring cameras that allow drivers to monitor the blind spot at the rear of the vehicle through a screen to ensure safety when reversing the vehicle, and surrounding detection cameras that can monitor the surroundings of the vehicle are installed.

[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 if the vehicle detects lane departure caused by driver inattention or drowsiness while driving, it will sound an alarm.

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

[0043] The camera angle adjustment device 10 is provided on the windshield 2 of the vehicle 1. The camera angle adjustment device 10 can adjust the angle of view of the camera module 200. This makes it possible to compensate for manufacturing tolerances of the camera module 200 and mounting tolerances to the vehicle 1, and adjust the angle of view within a range of directivity angles desired by the user.

[0044] The camera angle adjustment device 10 may include a bracket 100. The bracket 100 may be disposed on one side of the camera module 200. The bracket 100 may be disposed behind the camera module 200. The bracket 100 may be attached to a window glass 2 of a vehicle 1. The bracket 100 may rotatably support the camera module 200. At least a portion of the view angle adjustment member 300 and an elastic member 400 may be disposed on the bracket 100. The bracket 100 may include a main body 102, an extension portion 104, and a support portion 110.

[0045] The body 102 of the bracket 100 may support the housing 210 of the camera module 200. The body 102 may be disposed on one side or rear of the housing 210 of the camera module 200. The body 102 may be formed in a shape and size corresponding to the housing 210 of the camera module 200. Extension parts 104 may be formed on both ends of the body 102 of the bracket 100, and a support part 110 may be formed on an upper part.

[0046] The extensions 104 of the bracket 100 may be extended from both ends of the body 102. The extensions 104 of the bracket 100 may be coupled to the extensions 230 of the camera module 200. The extensions 104 of the bracket 100 may be coupled to the extensions 230 of the camera module 200 via a hinge. The extensions 104 of the bracket 100 may rotatably support the extensions 230 of the camera module 200. In an embodiment of the present invention, the extensions 104 are described as being extended from both ends of the body 102 to one side or rearward, but are not limited thereto and may be extended forward or in the outer circumferential direction from both ends of the body 102.

[0047] The support part 110 may be disposed on an upper portion of the body 102. The support part 110 may be formed by extending upward from an upper surface of the body 102. An elastic member 400 may be disposed on the support part 110. One side of the view angle adjustment member 300 may be disposed on the support part 110. The support part 110 may face the coupling part 220 of the camera module 200. The support part 110 may be spaced apart from the coupling part 220 of the camera module 200 by a certain distance. The support part 110 may include a first side wall 112, a second side wall 114, a third side wall 116, and a fourth side wall 118. One side of the view angle adjustment member 300 may include a first portion. One side of the view angle adjustment member 300 may include a first region. The other side of the view angle adjustment member 300 may include a second portion. The other side of the view angle adjustment member 300 may include a second region.

[0048] The first side wall 112 may be disposed between the camera module 200 and one side of the view angle adjustment member 300. The first side wall 112 may face the coupling portion 220 of the camera module 200. The first side wall 112 may face the second side wall 114. The first side wall 112 may be connected to the third side wall 116. The first side wall 112 may be connected to the fourth side wall 118. The first side wall 112 may include a first opening 1122 and a first groove 1124.

[0049] A part of the angle-of-view adjusting member 300 may be disposed in the first opening 1122 of the first side wall 112. The body 310 of the angle-of-view adjusting member 300 may be disposed in the first opening 1122 of the first side wall 112. A region in which the thread 312 is not present in the body 310 of the angle-of-view adjusting member 300 may be disposed in the first opening 1122 of the first side wall 112. The first opening 1122 of the first side wall 112 may be formed such that the length in the first direction is longer than the length in the second direction perpendicular to the first direction. The first opening 1122 of the first side wall 112 may be formed such that the length in the vertical direction is longer than the length in the horizontal direction. An end 320 of the angle-of-view adjusting member 300 may be disposed between the first opening 1122 and the second opening 1142.

[0050] The first groove 1124 of the first side wall 112 may be formed in a curved shape corresponding to one side surface of the stopper 330 of the view angle adjusting member 300.

One surface of the stopper 330 of the view angle adjusting member 300 may be disposed in the first groove 1124 of the first side wall 112. The size of the first groove 1124 of the first side wall 112 may be smaller than the size of one surface of the stopper 330 of the view angle adjusting member 300. As a result, the view angle adjusting member 300 can be finely rotated with respect to the first side wall 112, and damage to the product can be prevented.

[0051] The second sidewall 114 may face the first sidewall 112. The second sidewall 114 may be connected to a third sidewall 116. The second sidewall 114 may be connected to a fourth sidewall 118. The second sidewall 114 may include a second opening 1142 and protrusions 1144, 1146.

The second opening 1142 of the second side wall 114 may expose one end of the angle-of-view adjusting member 300 to the outside. Specifically, the second opening 1142 of the second side wall 114 may expose the tool groove 322 of the end 320 of the angle-of-view adjusting member 300 to the outside. This allows a user to easily change the length of the angle-of-view adjusting member 300 screwed to the coupling portion 220 of the camera module 200 by clamping a tool in the tool groove 322 and rotating it.

[0053] The protrusions 1144, 1146 of the second side wall 114 may include two protrusions 1144, 1146. The two protrusions 1144, 1146 may be formed on an inner surface of the second side wall 114 facing the first side wall 112, extending toward the other side or toward the first side wall 112. The two protrusions 1144, 1146 of the second side wall 114 may be formed in an area adjacent to a corner of the first side wall 112. The two protrusions 1144, 1146 of the second side wall 114 may be formed in an upper area of ​​the second side wall 114. The second area 420 of the elastic member 400 may be disposed between the two protrusions 1144, 1146 of the second side wall 114 and the bottom surface of the support 110. This makes it possible to prevent the elastic member 400 from being detached.

[0054] The third and fourth side walls 116, 118 may connect the first side wall 112 and the second side wall 114. The end portion 320 and the stopper portion 330 of the view angle adjusting member 300 and the elastic member 400 may be disposed in the space between the third side wall 116 and the fourth side wall 118.
