[0024] See also Figure 1-6In the utility model, a vehicle-mounted camera housing with a heat dissipation structure includes a base plate 1, a protective shell 5 and a chip 13. Four limiting columns 11 are fixedly installed on the inner wall of the base plate 1. Two groups of strip openings 21 are opened on the bottom surface of the protective shell 5. The inner wall of each group of strip openings 21 is clamped with a heat sink 3. The inner wall of each heat sink 3 is in contact with the outer surface of the limiting column 11. Four limiting holes 19 are opened on the front of the chip 13. A camera body 12 is installed on the front of the chip 13. The outer surface of each heat sink 3 is in contact with the outer surface of the camera body 12. The strip opening 21 and the limiting column 11 jointly limit the heat sink 3. By contacting the outer surfaces of the two heat sinks 3 with the outer surface of the camera body 12, the two heat sinks 3 can absorb the heat generated when the camera body 12 is running, and the heat sink 3 part located in the protective shell 5 can discharge the absorbed heat into the air.

[0025] Four support columns 20 are fixedly installed on the inner wall of the base plate 1, and a thread groove 18 is provided on the upper surface of each support column 20. Four first bolts 14 are provided on the outside of the base plate 1, and the bottom end of each first bolt 14 passes through the limiting hole 19 and extends to the inside of the thread groove 18. The bottom end of each first bolt 14 is threadedly connected to the inner wall of the thread groove 18. The four support columns 20 jointly support the chip 13. The four first bolts 14 can firmly install the chip 13 on the front side of the four support columns 20. A wire hole 7 is provided on the back side of the base plate 1. A wire 8 is connected to the back side of the chip 13. The other end of the wire 8 passes through the wire hole 7 and extends to the outside of the base plate 1. The wire 8 can be connected to the vehicle's driving system, so that the driver can easily obtain the picture taken by the camera body 12.

[0026] Four receiving grooves 6 are provided on the back of the base plate 1, and a through hole 17 is provided on the inner wall of each receiving groove 6. A second bolt 16 is provided inside each receiving groove 6. A sealing gasket 9 is installed on the front of the base plate 1. The four receiving grooves 6 can respectively receive the top ends of the four second bolts 16, and the sealing gasket 9 can effectively fill the gap between the protective shell 5 and the base plate 1. Four connecting blocks 10 are fixedly installed on the inner wall of the protective shell 5, and a threaded hole 15 is provided on the front of each connecting block 10. One end of each second bolt 16 passes through the through hole 17 and extends to the inside of the threaded hole 15, and one end of each second bolt 16 is threadedly connected to the inner wall of the threaded hole 15. By using the second bolts 16, the protective shell 5 and the base plate 1 can be firmly assembled together. Two fixing blocks 4 are fixedly installed on the left side and the right side of the base plate 1, and a fixing hole 2 is provided on the front of each fixing block 4. The assembler can firmly assemble the device with the vehicle body by using bolts to pass through the fixing holes 2.

[0027] The working principle of the utility model is:

[0028] First, the staff will respectively connect the two heat sinks 3 with the two limit columns 11, and make the outer surface of each heat sink 3 in close contact with the outer surface of the camera body 12. Then, the protective shell 5 and the base plate 1 are assembled together, and then the outer surface of one end of each heat sink 3 is connected with the strip opening 21. The two heat sinks 3 continuously absorb the heat generated by the camera body 12 during operation, and the external air flow of the protective shell 5 continuously absorbs the heat from the outer surfaces of the two heat sinks 3, so that the camera body 12 can achieve effective heat dissipation.
