Driving video recorder for automotive and having a fan
The present disclosure provides a driving video recorder for an automotive, which includes: a housing having a side wall, a top wall with an air outlet, and a bottom wall with an air inlet; a first electric fan arranged on the bottom wall above the air inlet and in a vertical middle plane of the housing for directing outside air into the housing; two sets of lenses for image capturing arranged at the side wall and positioned symmetrically on both sides of the vertical middle plane of the housing; and heat generating electrical components provided within the housing. The driving video recorder according to the present disclosure has a symmetrically distributed lens structure ensuring system stability, reliability, and enhanced functionality.
1. A driving video recorder for an automotive, comprising:
a housing having a top wall with an air outlet, a bottom wall with an air inlet, and a side wall connecting the top wall with the bottom wall;
a first electric fan arranged on the bottom wall above the air inlet and in a vertical middle plane of the housing for directing outside air into the housing;
two sets of lenses for image capturing arranged at the side wall, each of the two sets of lenses positioned entirely and symmetrically on opposing sides of the vertical middle plane of the housing to face opposite directions and share an optical axis; and
heat generating electrical components provided within the housing, the heat generating electrical components being symmetrically distributed on both sides of the vertical middle plane.
2. The driving video recorder according to claim 1 , wherein a second electric fan is arranged at the top wall below the air outlet for forcing hot air from the heat generating electrical components out of the housing.
3. The driving video recorder according to claim 2 , wherein the second electric fan is aligned with the first electric fan along the vertical middle plane of the housing.
4. The driving video recorder according to claim 1 , wherein the housing is a sphere-shaped housing.
5. The driving video recorder according to claim 1 , wherein the two lenses are panoramic fisheye lenses.
6. The driving video recorder according to claim 1 , wherein the heat generating electrical components are sensors, one or more digital signal processors, and memory components.
7. The driving video recorder according to claim 1 , wherein at least one of the heat generating electrical components is provided with a heat sink.
8. The driving video recorder according to claim 7 , wherein the heat sink is provided with fins for radiating heat.
9. The driving video recorder according to claim 8 , wherein the fins extend in a direction perpendicular to the vertical middle plane.
10. The driving video recorder according to claim 1 , wherein the housing with the side wall, the top wall and the bottom wall is integrally injection molded.
11. The driving video recorder according to claim 1 , wherein the side wall, the top wall and the bottom wall of the housing are formed separately and then assembled into the housing.
12. The driving video recorder according to claim 1 , further comprising a WiFi module.
13. The driving video recorder according to claim 1 , wherein the different directions of the two sets of lenses face are opposite directions.
14. The driving video recorder according to claim 1 , wherein the optical axes of the two sets of lenses coincide.
15. The driving video recorder according to claim 1 , wherein at least one of the two lenses has an optical axis perpendicular to and intersecting the vertical middle plane.
16. The driving video recorder according to claim 2 , wherein the first electric fan and the second electric fan are arranged to blow air in a same direction.
