Problems solved by technology

However, this design introduces a new field of view blockage
[0006] (3) Display and radar: install cameras and screen displays, or install microwave radar in blind spots, but these methods all have delays and are costly
[0008] However, the above technical solution uses three Fresnel lenses to form a lens group, and the structure is relatively complicated, which increases the production cost.

Embodiment 1

[0226] Embodiment 1: (applied to MPV, SUV and sedan)

[0227] S31: Select a negative Fresnel lens 1 with a focal length of f=-330mm (where the focal length f=-330mm is only a randomly selected negative Fresnel lens 1 with a smaller focal length, without other uniqueness), and use the negative Fresnel lens Er lens 1 center (concentric circle center) is an angle, obtains long=wide=8cm size (this size is the comparatively suitable size selected according to the model of MPV, SUV and car);

[0228] S32: Sit in the driving position and adjust to the daily driving posture, then face the threaded surface of the negative Fresnel lens 1 to the human body, rotate the negative Fresnel lens 1 so that the center of the negative Fresnel lens 1 (the center of the concentric circle) ) is placed in the upper right corner, and then the center of the upper edge of the negative Fresnel lens 1 is fixed to the position of the connecting part 22 of the suction cup 2 through double-sided adhesive tap...

Abstract

The invention relates to the field of vehicle safety driving, and discloses a vehicle A column blind area eliminating device based on a negative Fresnel lens and a matching method. The device comprises a lens and a connecting sucker; the lens is the negative Fresnel lens; and the circle center of a concentric circle of the negative Fresnel lens is deviated from the geometric center. The matching method comprises the following steps: the selected lens and the lens mounting position are determined by adopting mathematical analysis; specifically, the lens is wider, the view expansion is larger; the focal distance is smaller, the view improvement is larger; and the lens is nearer an A column, the view expansion is better. In the vehicle A column blind area eliminating device based on the negative Fresnel lens and the matching method, the optimal mounting position is mathematically derived, so that the refraction performance effect of the negative Fresnel lens is exerted to the greatest extent; even if a single negative Fresnel lens is adopted, a vehicle A column blind area can be effectively eliminated; and the device is simple in structure, low in cost and easy to popularize.

Description

technical field [0001] The invention relates to the field of automobile safe driving, in particular to an automobile A-pillar blind area elimination device and matching method based on a negative Fresnel lens. Background technique [0002] Generally, there are three pillars on each side of the body of a car, and the connecting pillars connecting the roof and the engine compartment in the left and right fronts of the car are called A-pillars. The A-pillar is an indispensable part of the current mainstream frame structure, but the existence of the A-pillar will inevitably Form a visual blind spot, block the driver's line of sight, and bring safety hazards. Therefore, there is a dilemma in the size of the cross-sectional area of ​​the A-pillar. If it is too small, it will lead to insufficient strength of the body, and if it is too large, it will affect the driver's vision. [0003] At present, common solutions for A-pillar blind spots include: [0004] (1) Improve the A-pillar...
