Light direction order arrange after main cylinder minus lens and rear main cylinder plus lens；Between rear main cylinder minus lens and rear main cylinder plus lens
Airspace is more than five times of front main cylinder and rear main cylinder spacing；When thermal compensation expansion ring because of variations in temperature on optical path direction
When producing flexible, front main cylinder moves the distance generation change before making between main cylinder and rear main cylinder under the driving of thermal compensation expansion ring.
Sky at a temperature of the standard procedure of camera lens assembly process, between described front main cylinder plus lens and rear main cylinder minus lens
Gas interval is 2.2mm.
After described, the airspace between main cylinder minus lens and rear main cylinder plus lens is 12mm.
Main cylinder plus lens before trim ring is fixing before described front main cylinder；After described between main cylinder minus lens and rear main cylinder plus lens
Separate with BC spacer ring, main cylinder plus lens after trim ring is fixing after described rear main cylinder.
The outer housing of described camera lens is one-body molded.
Described lens focus is 19mm.
The optics volume of described camera lens is long 29.1mm, wide 19.6mm, high 19.6mm.
In the present invention, described thermal compensation expansion ring one end is fixed at outer housing, and the other end is connected with described front main cylinder；Work as heat
When compensation expansion ring produces flexible because of variations in temperature on optical path direction, front main cylinder moves under the driving of thermal compensation expansion ring
The distance between front main cylinder and rear main cylinder is made to produce change；Front main cylinder plus lens it is fixed with, in camera lens assembler in described front main cylinder
At a temperature of the standard procedure of sequence, the airspace between described front main cylinder plus lens and rear main cylinder minus lens is 2.2mm；After described
Airspace between main cylinder minus lens and rear main cylinder plus lens is 12mm；Described lens focus is 19mm；This product presses focal length
Value measurement belongs to fish eye lens, and before driving with thermal compensation expansion ring in design, main cylinder movement is to compensate the temperature deformation effect of camera lens
Should, and the distance between front main cylinder and rear main cylinder be far smaller than after lens pitch in main cylinder lens set so that the shape of expansion ring
Change can significantly change the distance between front main cylinder and rear main cylinder, thus lens optical characteristic is produced considerable influence, with simply
Lens construction achieves the temperature self-adaptation of infrared lens, simple in construction, and volume is little, is suitable for the uncooled ir optics of miniaturization
System uses, and this simple lens construction possesses preferable vibration resistance, is suitable for vehicle environment.
In the present invention, the outer housing of described camera lens is one-body molded；Main cylinder plus lens before trim ring is fixing before described front main cylinder；Institute
Separating with BC spacer ring between main cylinder minus lens and rear main cylinder plus lens after stating, after after described rear main cylinder, trim ring is fixing, main cylinder is the most saturating
Mirror；This design possesses good sealing property and resistance to shock, is suitable for using in the automotive environment, the supporting construction letter of this structure
Clean, it is simple to carry out Rigidity Calculation, it is also beneficial to reduce resonance, when camera lens is for country vehicle, the outer housing of camera lens uses
The outer wall of larger thickness, effectively to prevent resonance, promotes the vibration resistance of camera lens further.
