Preferably, the light-sensing detecting member 7 is preferably a light-sensing sensor for detecting the intensity of light irradiated in front of the lens 1.
The filter component is arranged on the side of the lens 1 and comprises a filter 4 and a storage bin 2, the top end of the storage bin 2 is fixed on the outer side wall of the shell of the lens 1, and the opening of the storage bin 2 is arranged towards the lens 1. The optical filter 4 is telescopically arranged in the storage bin 2, and the optical filter 4 can extend out of the storage bin 2 and is positioned in front of the lens 1 or can be contracted in the storage bin 2. Specifically, the optical filter 4 can extend out of the storage bin 2 to shield the front of the lens 1 or shrink into the storage bin 2 according to the illumination intensity detected by the light sensation detector 7.
As shown in fig. 4-6, when the light sensation detecting element 7 detects that the illumination intensity in front of the lens 1 is high, the optical filter 4 extends out of the storage bin 2 and moves to the front of the lens 1, light can enter the lens 1 after passing through the optical filter 4, and the optical filter 4 filters out a part of strong light, so that the lens 1 is not affected by the strong light, and the imaging of the lens 1 is clear. As shown in fig. 1-3, when the intensity of the illumination in front of the lens 1 is detected to be not high, the optical filter 4 is received in the storage bin 2 and is not blocked in front of the lens 1, so as to avoid the too low intensity of the illumination collected by the lens 1. The camera device can be used on a vehicle to avoid the image violence caused by the overhigh illumination intensity of the lens 1, effectively ensure the definition of a monitoring picture, and facilitate the driver to clearly judge the road condition and safely drive through the monitoring picture.
Preferably, the filter assembly further comprises a driving assembly for driving the filter 4 to move to the front of the lens 1 to shield the lens 1, or to move into the storage bin 2 to no longer shield the lens 1.
Preferably, the filtering assembly further comprises a cleaning sealing ring 5, the cleaning sealing ring 5 is arranged at an opening of the storage bin 2, a through hole matched with the optical filter 4 is formed in the cleaning sealing ring 5, and the optical filter 4 is cleaned when the cleaning sealing ring 5 is used for the optical filter 4 to pass through the through hole. The cleaning sealing ring 5 is made of rubber or silica gel, and the cleaning sealing ring 5 can scrape off dirt on the surface of the optical filter 4 in the movement process of the optical filter 4. The camera device further includes a gasket 6 disposed at a front end of the lens 1. Specifically, the gasket 6 is disposed at the front end of the housing of the lens 1 and has a ring shape. The gasket 6 may also scrape off dirt from the filter 4 during movement of the filter 4.
Preferably, the filter assembly further comprises a scissor assembly 3, a first end of the scissor assembly 3 is hinged with the filter 4, and a second end is hinged with the bottom of the storage bin 2. The output end of the driving component is connected with a hinge point in the middle of the bottom of the scissor component 3, and the driving component can drive the hinge point to move along the moving direction of the optical filter 4 so as to drive the scissor component 3 to stretch and retract, so that the optical filter 4 is positioned in the storage bin 2 or stretches out to be positioned in front of the lens 1.
The camera device further comprises a controller, the driving assembly and the light sensation detection piece 7 are electrically connected with the controller, and the controller controls the driving assembly to run according to the intensity of illumination detected by the light sensation detection piece 7. If the illumination intensity is too high, the driving component is controlled to drive the filter 4 to move. Preferably, the driving assembly is a cylinder in the embodiment, and may also be a hydraulic cylinder or an electric cylinder in other embodiments.
The more specific working process of the camera device is as follows: light sense detection piece 7 detects the illumination intensity in 1 the place ahead of camera lens, then feed back detected signal to the controller, the controller judges whether illumination intensity is greater than the default, if be greater than the default (also be the illumination intensity in 1 the place ahead of camera lens higher), the outside motion of fork subassembly is cut in the drive of controller air drive subassembly, in order to order about light filter 4 outside motion, in order to shelter from in the place ahead of camera lens 1, the light in 1 the place ahead of camera lens passes through in light filter 4 can enter into camera lens 1 later, light filter 4 can filter some highlight, ensure that camera lens 1 does not receive the highlight influence, it is clear to make camera lens 1 take images. If the light intensity is smaller than the preset value (namely, the light intensity in front of the lens 1 is low), the controller air driving assembly drives the scissor assembly to move inwards so as to drive the optical filter 4 to move inwards, and the optical filter is stored in the storage bin 2 and does not shield the lens 1 any more. The illumination intensity collected by the lens 1 is prevented from being too low.
The embodiment also discloses a vehicle which comprises the camera device and is mainly a commercial transport vehicle.
