Description
Technical field
The utility model relates to the technical field of vehicle-mounted camera, specially a kind of metal laser rear shell penetration welding
Vehicle-mounted camera.
Background technique
Existing vehicle-mounted camera, rear shell and front housing have locked compression seal pad, Lai Shixian by screw connection simultaneously
The waterproof of front and rear casing, rear shell and front housing are plastic construction injection molding, while rear shell squeezes inner casing, inner casing squeezes camera lens, mirror
O-ring is arranged in the mounting hole inner ring of head and front housing, so that the waterproof of front housing and camera lens is realized, positioned at the heat of the sensor of inner cavity
Can only be by external plastic parts slowly to exterior conductive, which has the drawback that gasket and O-ring are easily deformed,
And then lead to waterproof failure；The heat dissipation of sensor is slow, and temperature rise is excessively high and then leads to that image noise is serious, decoking even occurs；
Overall structure does not have shielding properties, big by extraneous electromagnetic interference, influences the stabilization of image.
Summary of the invention
In view of the above-mentioned problems, the utility model provides a kind of vehicle-mounted camera of metal laser front housing penetration welding,
Its front housing, rear shell weld together, and are not required to increase additional waterproof part, thoroughly completely cut off outside moisture and enter body interior, whole
The perfect heat-dissipating of body, and the electromagnetic interference of maskable outside.
A kind of vehicle-mounted camera of metal laser front housing penetration welding, it is characterised in that: it includes front housing, rear shell, biography
Sensor substrate, the front housing, rear shell are metal material, and the front end of the front housing is installed with preceding convex lens, the use of the front housing
In the periphery of the rear end face of the side nose of positioning rear shell, inner groovy, the front end corresponding to the inner groovy of the side nose are set
Face is plane, and the part towards the inner groovy of the rear shell is protrusion positioning, the sensor base plate be installed in it is described before
On the rear end substrate installation part of shell, the rear end connector of the sensor base plate is arranged backward, and the protrusion positioning of the rear shell is embedding
It is welded to connect in inner groovy loaded on the front housing and by laser penetration formula, formation closure weld seam, the sensor base plate,
Rear end connector is located at rear shell cover together in the installation cavity after front housing.
It is further characterized by
The rear end face of the rear shell is provided with rear convex external interface, when the rear shell cover is loaded on the front housing, the rear end
Connector positioning and plug-in mounting is after described in convex external interface, so that the data of sensor base plate conveniently pass through line transmission to outer
Portion；
Laser penetration formula welding transmits the thermal energy of light to raised positioning ring, interior concave ring groove by the front end face of side nose
Contact with each other face；
The side nose with a thickness of 0.4mm~2mm, it is ensured that effective reliable progress of laser fuU penetration welding.
After the utility model, front housing, rear shell are welded together by laser fuU penetration welding, are not required to increase additional anti-
Wet part thoroughly completely cuts off outside moisture and enters body interior, since front housing, rear shell are metal material, whole thermal diffusivity
Can be good, and the electromagnetic interference of maskable outside.
Detailed description of the invention
Fig. 1 is the main view sectional structure simplified schematic diagram of the utility model；
Title corresponding to serial number is as follows in figure:
Front housing 1, rear shell 2, sensor base plate 3, preceding convex lens 4, side nose 5, front end face 51, inner groovy 6, protrusion positioning 7,
Rear end substrate installation part 8, rear end connector 9, installation cavity 10, rear convex external interface 11.
Specific embodiment
A kind of vehicle-mounted camera of metal laser front housing penetration welding, see Fig. 1: it includes front housing 1, rear shell 2, sensor
Substrate 3, front housing 1, rear shell 2 are metal material, and the front end of front housing 1 is installed with preceding convex lens 4, and front housing 1 is used to position rear shell 2
The periphery of rear end face of side nose 5 inner groovy 6 is set, the front end face 51 corresponding to inner groovy 6 of side nose 5 is plane, after
The part towards inner groovy 6 of shell 2 is protrusion positioning 7, and sensor base plate 3 is installed on the rear end substrate installation part 8 of front housing 1,
The rear end connector 9 of sensor base plate 3 arranges that the protrusion positioning 7 of rear shell 2 in the inner groovy 6 of front housing 1 and is led to backward
Too drastic light-penetrating type is welded to connect, forms closure weld seam, and sensor base plate 3, rear end connector 9 are located at rear shell 2 and are covered on front housing 1
In installation cavity 10 afterwards.
The rear end face of rear shell 2 is provided with rear convex external interface 11, and when the lid of rear shell 2 is loaded on front housing 1, rear end connector 9 positions
It is plugged in rear convex external interface 11, so that the data of sensor base plate 3 conveniently pass through line transmission to outside；
The welding of laser penetration formula positions 7, inner groovy 6 by thermal energy to the protrusion that the front end face 51 of side nose 5 transmits light
Contact with each other face；
Side nose 5 with a thickness of 0.4mm~2mm, it is ensured that effective reliable progress of laser fuU penetration welding.
Front housing, rear shell are welded together by laser fuU penetration welding, are not required to increase additional waterproof part, thoroughly isolation is outer
Boundary's moisture enters body interior, since front housing, rear shell are metal material, whole perfect heat-dissipating, and maskable outside
Electromagnetic interference.
Specific embodiment of the utility model is described in detail above, but content is only what the utility model was created
Preferred embodiment should not be construed as limiting the practical range of the utility model creation.All create according to the utility model is applied
All the changes and improvements made by range etc., shall still fall within the scope of this patent.
