Camera module{CAMERA MODURE FOR VEHICLE}

This embodiment relates to a camera module.

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.

In the case of a camera module mounted on a vehicle, a plurality of substrates may be placed inside the camera module, and a structure capable of fixing the plurality of substrates spaced apart inside the camera module is required.

In some cases, the coupling portion 350, together with the contact portion 356, may have elastic force directed outward from the bottom of the fence portion 342. The protrusion length of the bent portion 369 from the side of the second substrate 320 before coupling of the rear body 110 is the bending length from the side of the second substrate 320 after coupling of the rear body 110. It may be larger than the protruding length of the portion 369. When the rear body 110 is coupled, the outer surface of the bent portion 369 may press the inner surface of the rear body 110 by elastic force.

According to the above structure, when the rear body 110 is coupled, the coupling portion 350 is connected to the second substrate 320 by contact between the inner surface of the rear body 110 and the bent portion 369. ) can be coupled to the groove 325. In addition, there is an advantage that the coupled state of the substrate module 300 within the rear body 110 can be maintained more firmly.

Meanwhile, a grounding structure of the substrate module 300 can be implemented by contact between the shield member 340 and the rear body 110.

Claims (10)

a front body containing a hole;
a lens module at least partially coupled to the hole;
a rear body coupled to the rear of the front body; and
Includes a substrate module disposed in the rear body,
The substrate module is,
A first substrate on which an image sensor is placed;
a second substrate disposed behind the first substrate; and
It includes a shield member coupled to the first substrate and the second substrate,
A protrusion is formed on a side of the second substrate,
The shield member includes a coupling hole into which the protrusion is coupled,
A camera module in which the cross-sectional area of the protrusion is smaller than the cross-sectional area of the coupling hole.
According to claim 1,
The inner surface of the coupling hole has a first surface, a second surface disposed opposite to the first surface, a third surface connecting the first surface and the second surface, and a third surface connecting the first surface and the second surface. Comprising a fourth side opposite to the third side,
A camera module in which the outer surface of the protrusion is in contact with any one of the first to fourth surfaces.
According to claim 2,
A camera module wherein the outer surface of the protrusion is spaced apart from any one of the first to fourth surfaces and the other three surfaces.
According to claim 1,
The shield member is,
a fence portion disposed between the first substrate and the second substrate; and
It protrudes downward from the bottom of the fence portion and includes a coupling portion in which the coupling hole is formed,
A groove is formed on a side of the second substrate where the coupling portion is joined,
The protrusion is a camera module disposed on the bottom of the groove.
According to claim 4,
A camera module in which a slit in a shape that is recessed upward from other areas is disposed outside the area of the lower surface of the fence unit connected to the top of the coupling unit.
According to claim 4,
A camera module extending downward from the bottom of the coupling portion and including a contact portion in contact with an inner surface of the rear body.
According to claim 4,
The contact part is,
a first region extending downward from the bottom of the coupling portion;
a second area extending downward from the bottom of the first area; and
A camera module disposed between the first area and the second area and including a bent portion in contact with an inner surface of the rear body.
According to claim 7,
The contact part is a camera module having elastic force such that the outer surface of the bent part presses the inner surface of the rear body.
According to claim 7,
The first area is arranged at an angle so that the distance to the inner surface of the rear body becomes shorter as it goes downward,
The second area is a camera module arranged at an angle so that the distance to the inner surface of the rear body increases as it moves downward.
According to paragraph 1,
The length of the protrusion in the first direction is 0.4 mm to 0.6 mm or less than the length of the first direction of the coupling hole,
The camera module wherein the second direction length of the protrusion perpendicular to the first direction is 0.2 mm to 0.3 mm or less than the second direction length of the coupling hole.
