Description

Technical Field

[0001] This utility model relates to the field of panoramic camera technology, and specifically to a high-temperature resistant panoramic camera structure. Background Technology

[0002] Currently, panoramic cameras with multiple lenses in multiple directions are available on the market, such as multi-view panoramic cameras. These panoramic cameras include a housing, multiple camera modules evenly arranged around the center line of the housing, and each camera module includes a fisheye lens, a lens control board, a lens mount connected to the lens control board, and a photoelectric sensor module on the lens control board corresponding to the fisheye lens. The housing also contains a main control board connected to each lens control board, and each fisheye lens protrudes from the surface of the housing to achieve multi-directional imaging.

[0003] However, due to the increased number of camera modules, multi-view panoramic cameras generate significantly more heat during operation, which is concentrated inside the housing and is not conducive to rapid dissipation. This is especially true in hot summers or when the ambient temperature is very high, as they cannot dissipate heat quickly, resulting in poor high-temperature resistance and a short service life.

[0004] The purpose of this invention is to provide a high-temperature resistant panoramic camera structure that is reasonably designed and reliable in use, solving the problem of insufficient heat dissipation when multiple camera modules are working simultaneously. It has strong high-temperature resistance and a long service life.

[0005] The technical solution of this utility model is:

[0011] In the aforementioned high-temperature resistant panoramic camera structure, the output cable of the lens control board is connected to the input cable of the main control board using a quick-connect plug.

[0012] The beneficial effects of this utility model are:

[0013] 1. Thermally conductive gel is used to absorb the heat generated by electrical components on each lens control board and main control board, and then a cooling fan removes the heat accumulated in the thermally conductive gel.

[0018] The present invention will be described in detail with reference to the accompanying drawings.

[0019] like Figure 1 , Figure 2 As shown, the high-temperature resistant panoramic camera structure includes a housing and four camera modules evenly arranged around the center line of the housing. Each camera module includes a fisheye lens 1, a lens control board 9, a lens mount 11 connected to the lens control board 9, and a photoelectric sensing module 10 disposed on the lens control board 9 and corresponding to the fisheye lens 1.

[0020] The housing is a spherical shell 2, with the fisheye lenses 1 of each camera module embedded in its surface. A ring-shaped aluminum bracket 3 is built into the top of the spherical shell 2, and the upper edge of the lens control board 9 of each camera module is connected and fixed to the ring-shaped aluminum bracket 3. In this embodiment, the ring-shaped aluminum bracket 3 consists of an upper connecting ring, a lower ring plate, and multiple connecting pieces connecting the upper connecting ring and the lower ring plate. The upper connecting ring is injection molded integrally with the spherical shell 2, and its outer surface is exposed on the surface of the spherical shell 2. The lower ring plate is parallel to the horizontal plane and connected and fixed to the upper edge of the lens control board 9.

[0021] Each lens control board 9 is evenly arranged around the center line of the housing to form a clamping cavity. The top surface of the spherical shell 2 is provided with a hollow top cover 4 corresponding to the clamping cavity, and the inner surface of the hollow top cover 4 is provided with a filter screen 5. A cooling fan 6 is clamped between the upper surface of the annular aluminum hanger 3 and the hollow top cover 4, and the outlet of the cooling fan 6 faces the clamping cavity.

[0022] A thermally conductive gel 8 is clamped in the clamping cavity. The thermally conductive gel 8 contains a tree-shaped heat dissipation tube bundle 7, which consists of multiple inlet pipes and outlet pipes 17 connected to each inlet pipe. The inlet of each inlet pipe of the heat dissipation tube bundle 7 is opposite to the outlet of the cooling fan 6.

[0023] The bottom of the spherical shell 2 is provided with a split base 16, and a main control board 13 connected to each lens control board 9 is fixed inside the split base 16. The output cable of the lens control board 9 and the input cable of the main control board 13 are connected by a quick connector 12.

[0024] In this embodiment, the split base 16 is provided with multiple connecting posts 14 corresponding to the main control board 13. A support column 18 is provided at the bottom center of the split base 16. A terminal block 22 for connecting to the output cable of the main control board 13 is provided on the outer wall of the support column 18. The bottom surface of the thermally conductive gel 8 contacts the electrical components 15 on the main control board 13. The main control board 13 is provided with a clearance through-hole corresponding to the outlet pipe 17 of the heat dissipation tube bundle 7. The outlet of the outlet pipe 17 of the heat dissipation tube bundle 7 passes through the clearance through-hole and extends to the outside of the split base 16. Specifically, a flange 20 is provided at the lower end of the support column 18 and is connected and fixed to the bracket 19 using the flange 20. The outlet of the outlet pipe 17 of the heat dissipation tube bundle 7 is led to below the top surface of the bracket 19. The bracket 19 is a portal frame. The upper surface of the portal frame is provided with a through-hole that mates with the outlet of the outlet pipe 17. A sealing ring 21 is provided on the inner wall of the through-hole.

[0025] During assembly, first assemble each camera module inside the spherical shell 2; then open the hollow top cover 4 and fix the heat dissipation fan 6 to the upper surface of the annular aluminum bracket 3; then insert the thermal conductive gel body 8 and the tree-shaped heat dissipation tube bundle 7, which are fixed as one piece, into the clamping cavity; next, the outlet pipe 17 of the heat dissipation tube bundle 7 passes through the clearance through hole on the main control board 13, the lower end of the support column 18, and the through hole of the bracket 19, and the output cable of the lens control board 9 is connected to the input cable of the main control board 13 using the quick connector 12; finally, connect and fix the split base 16 to the spherical shell 2.

[0026] During use, the four camera modules generate a large amount of heat. The thermal conductive gel 8 absorbs the heat generated by the electrical components on the lens control boards 9 and the main control board 13. The cooling fan 6 is turned on to introduce external air into the heat dissipation tube bundle 7, which then carries away the heat accumulated in the thermal conductive gel 8 and finally discharges it through the outlet pipe 17 of the heat dissipation tube bundle 7.

[0027] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
