Abstract
Automobile anti-dead angle device, comprising one can the support of adjusting angle, and what support one end was removable is connected on shield glass, and connection a slice that the support other end is removable bears Fresnel lens.Negative Fresnel lens mainly plays a part to increase visual angle, such as: make the dead angle area originally blocked by automobile A column image in driver's seat by bearing Fresnel lens, its principle and concavees lens similar.But, if use common concavees lens to substitute negative Fresnel lens, although also can visual angle be increased, but there will be that corner is dimmed, fuzzy, the phenomenon of imaging distortion, this is because the refraction of light only occurs in the interface of medium, convex lens sheet is thicker, and the part of light rectilinear propagation in glass can make light attenuation.And technique scheme have employed negative Fresnel lens, while increase visual angle, effectively can ensure image quality, meet chaufeur observation habit, contribute to the traffic accident rate reduced because blind area causes.
Description
Technical field
The utility model relates to a kind of optical viewing arrangement for automobile, specifically a kind of automobile anti-dead angle device.
Background technology
Automotive visibility dead angle, is also called blind area, refers in the scope of eyesight, and the obstacle caused because of automobile itself and the place can't see be the A post of automobile, B post and C post especially, often forms blind area to driver and crew.In road traffic accident, some is that motorist is off one's guard blind area and occurring.
In order to reduce because the A post of automobile, B post and C post cause blind area, normally in car, install one or more plane mirrors additional, or installing dead angle radar additional, to obtain wider field range.
Chaufeur observation habit do not checked by catadioptre and dead angle radar, therefore still needs to carry out perfect to automobile anti-dead angle technology.
Utility model content
The utility model proposes a kind of automobile anti-dead angle device, it meets chaufeur observation habit, has applicable field range.
To achieve these goals, the utility model have employed following technical scheme.
Automobile anti-dead angle device, comprising one can the support of adjusting angle, and what support one end was removable is connected on shield glass, and connection a slice that the support other end is removable bears Fresnel lens.
As the improvement of technique scheme, described support is sucker stand, and its bottom is sucker, and sucker is for being adsorbed on shield glass.
Further, described support has the joint of at least one angle adjustable, for adjusting the angle of negative Fresnel lens.
Preferably, the light of negative Fresnel lens is facing to front windshield, and the line of negative Fresnel lens is facing to chaufeur.
In technique scheme, negative Fresnel lens mainly plays a part to increase visual angle, such as: make the dead angle area originally blocked by automobile A column image in driver's seat by bearing Fresnel lens, its principle and concavees lens similar.But, if use common concavees lens to substitute negative Fresnel lens, although also can visual angle be increased, but there will be that corner is dimmed, fuzzy, the phenomenon of imaging distortion, this is because the refraction of light only occurs in the interface of medium, convex lens sheet is thicker, and the part of light rectilinear propagation in glass can make light attenuation.And technique scheme have employed negative Fresnel lens, while increase visual angle, effectively image quality can be ensured.
Therefore compared with prior art, the utility model has following beneficial effect:
Automobile of the present utility model anti-dead angle device, have employed negative Fresnel lens, increases the visual angle of chaufeur, there is applicable field range, effectively can ensure image quality while increase visual angle, meet chaufeur observation habit, contribute to the traffic accident rate reduced because blind area causes.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is STRUCTURE DECOMPOSITION schematic diagram of the present utility model.
Fig. 3 is the structural representation of negative Fresnel lens of the present utility model.
Fig. 4 is principle of work schematic diagram of the present utility model.
Detailed description of the invention
As depicted in figs. 1 and 2, automobile anti-dead angle device, comprising one can the support 1 of adjusting angle, and what support 1 one end was removable is connected on shield glass, and connection a slice that support 1 other end is removable bears Fresnel lens 2.
As depicted in figs. 1 and 2, described support 1 is sucker stand, and its bottom is sucker 11, and sucker is for being adsorbed on shield glass; Described support 1 has joint 12 and the joint 13 of two angle adjustables, for adjusting the angle of negative Fresnel lens 2.
Shown in Fig. 2, one jiao of perforation of negative Fresnel lens 2, coordinates this hole to be fixed on support 1 by negative Fresnel lens 2 by bolt.
As shown in Figure 3, negative Fresnel lens 2 one side be light face, and another side is line face, and in preferably embodiment, the light of negative Fresnel lens 2, facing to front windshield, bears the line of Fresnel lens facing to chaufeur.This embodiment can alleviate the imaging region normal rates that chaufeur is observed, and picture substantially can not distortion distortion.
As shown in Figure 4, the utility model is arranged on the negative Fresnel lens 2 of shield glass 3 mainly to be play a part to increase visual angle, make the dead angle area (i.e. scope folded by two dotted lines) originally blocked by automobile A column 4, image in chaufeur 5 visual field by negative Fresnel lens 2, while increase visual angle, effectively can ensure image quality, meet chaufeur observation habit, contribute to the traffic accident rate reduced because blind area causes.
For a person skilled in the art, the structure that can disclose according to the utility model and principle obtain other various corresponding change and distortion, and all these change and distortion all belongs to protection category of the present utility model.
