Novel focusing vehicle-mounted camera

Abstract

The invention provides a novel focusing vehicle-mounted camera capable of enabling a camera to be always in an optimal clear state and guaranteeing the imaging quality of the camera. The novel focusing vehicle-mounted camera comprises a front shell, a rear shell, a sensor substrate and a lens, wherein a convex lens is fixedly arranged at the front end of the front shell; a plurality of thickness direction penetrating holes are arranged in the periphery of the sensor substrate; an electrode bushing is fixedly arranged in each thickness direction penetrating hole; each electrode bushing is fixedly connected to a corresponding electrode bar; the lower end of each electrode bar is fixedly connected to a corresponding mounting position of the front shell; an adjusting distance is reserved between the sensor substrate and the corresponding mounting position of the front shell; the sensor substrate and the front shell are connected through the electrode bar to form an integral structure; thesensor substrate is connected to each electrode bushing through a circuit; the rear shell covers the front shell to form a mounting cavity; and the sensor substrate is arranged in the mounting cavity.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted cameras, in particular to a novel focusing vehicle-mounted camera. Background technique [0002] Existing car cameras, see figure 1 , the back shell e and the front shell d are connected and locked with the compression gasket b through the screw a to realize the waterproof of the front and rear shells, the rear shell e squeezes the inner shell f, the inner shell f squeezes the lens c, and the lens c and the front shell d squeeze The O-ring g is used to realize the waterproofing of the front shell and the lens. Its focal length adjustment method fixes the sensor h and the inner shell f together, so that the lens c and the inner shell f can be adjusted up and down through threads to complete the focus adjustment. Its disadvantages As follows: When the rear shell e presses the inner shell f downward, the inner shell f is deformed by force, which changes the relative distance between the PCBA...

[0002] Existing car cameras, see figure 1 , the back shell e and the front shell d are connected and locked with the compression gasket b through the screw a to realize the waterproof of the front and rear shells, the rear shell e squeezes the inner shell f, the inner shell f squeezes the lens c, and the lens c and the front shell d squeeze The O-ring g is used to realize the waterproofing of the front shell and the lens. Its focal length adjustment method fixes the sensor h and the inner shell f together, so that the lens c and the inner shell f can be adjusted up and down through threads to complete the focus adjustment. Its disadvantages As follows: When the rear shell e presses the inner shell f downward, the inner shell f is deformed by force, which changes the relative distance between the PCBA and the lens, and then causes defocusing, resulting in blurred images, seriously affecting the quality, poor stability, and poor quality. The rate is high; and the torque between the lens c and the inner shell f is difficult to control, debris is easily generated during production, and black spots appear in the image
