Abstract

The utility model relates to the technical field of vehicles, and discloses a rearview mirror system. The rearview mirror system mainly comprises a fixed support, a mirror body, a steering mechanism and a control circuit, wherein a steering gear is arranged on the fixed support; the steering mechanism comprises a servo motor, a gear set and a worm; and the rear side of the mirror body is joined with the steering mechanism. When vehicles run, the control circuit drives the servo motor through judging the steering directions or lane changing directions of drivers according to turn lights which are turned on by the drivers, furthermore, the worm is driven to drive the steering mechanism to rotate through the steering gear, and the mirror body which is connected with the steering mechanism is deflected to left or right to form a fixed angle, so that the drivers can obtain the required view angles for vehicle turning or lane changing according to the deflection of the mirror body.

Description

A kind of rear-view mirror system

Technical field

The utility model relates to the vehicle technology field, relates in particular to a kind of rear-view mirror system.

Background technology

At present, in Vehicle Driving Cycle, steerman is mainly to rely on the means of the back mirror of the back mirror of the right and left and Che Nei as judgement rear view of vehicle situation, yet, the visual angle that general back mirror provides is limited, in the Vehicle Driving Cycle process, there will be visual dead angles when lane change or turning, cause steerman can't really grasp the situation of rear view of vehicle, therefore, a kind of convex catadioptre be affixed on the script back mirror has appearred on the market, convex minute surface design by the convex catadioptre, provide wider visual angle to steerman, make steerman grasp the vehicle condition at rear, to promote traffic safety.

Yet, driving habit difference due to each steerman, this convex catadioptre can not meet all steermans fully, this be because, the convex catadioptre is to be attached on back mirror, and when steerman is watched back mirror, the image of back mirror and the image that the convex catadioptre presents can overlap originally, the identification of must diverting one's attention in the steerman startup procedure, have influence on the safety of driving on the contrary.Moreover, because the convex catadioptre is the design of convex minute surface, though therefore can provide than wide viewing angle, but can cause the error of distance perspective, can understand the rear view of vehicle vehicle condition though make steerman, but can't determine the distance between front vehicle and steering vehicle, meet accident in the time of will causing lane change when serious, or bump against obstacle while stopping in reversing, reversing.

The utility model content

The purpose of this utility model is to provide a kind of rear-view mirror system, makes steerman can obtain in time needed field-of-view angle, the safety of driving with raising when Vehicular turn or lane change.

For achieving the above object, rear-view mirror system provided by the utility model comprises:

One minute surface body; One fixed support, be positioned at the rear of described minute surface body and relative fixing with described minute surface body, and described fixed support bottom is provided with a steering gear; One steering hardware, described steering hardware is positioned at described minute surface body rear, and described steering hardware comprises a gear cluster, a scroll bar and a servomotor, the described scroll bar action of the described gear set drive of described servo motor driven, described scroll bar and steering gear engagement, drive described fixed support and rotate; And a control circuit, described control circuit is connected with the indicator signal, by the left indicator signal of sources discrimination or the right lamp signal of detecting pulse wave, and drives described servomotor to rotate according to differentiating result.

In technical solutions of the utility model, while by control circuit, detecting the opening direction lamp, the pulse wave produced is from left indicator or from the right lamp, and then control minute surface body turns left or turning clockwise, thereby required wider field-of-view angle while making steerman obtain Vehicular turn or lane change by the deflection of minute surface body, contribute to observe the situation at steering vehicle rear, greatly improved the safety of driving.

The specific embodiment

As shown in FIG. 1 to 3, the utility model a kind of rear-view mirror system is provided, it mainly comprises:

One minute surface body 2;

One fixed support 1, be positioned at the rear of described minute surface body 2 and relative fixing with described minute surface body 2, and described fixed support 1 bottom is provided with a steering gear 11;

One steering hardware 3, described steering hardware 3 is positioned at described minute surface body 2 rears, described steering hardware 3 comprises a gear cluster 32, a scroll bar 33 and a servomotor 31, described servomotor 31 drives described gear cluster 32 to drive described scroll bar 33 actions, described scroll bar 33 and steering gear 11 engagements, drive described fixed support 1 and rotate;

And a control circuit 4, described control circuit 4 is connected with the indicator signal, by the left indicator signal of sources discrimination or the right lamp signal of detecting pulse wave, and drives described servomotor 31 to rotate according to differentiating result.

As shown in Fig. 1～Fig. 5, rear-view mirror system provided by the utility model, in Vehicle Driving Cycle, steerman beats that left indicator is prepared or left during lane change, control circuit 4 detects the left indicator of vehicle and lights produced pulse wave, described control circuit 4 drives servomotor 31, servomotor 31 drives scroll bar 33 by gear cluster 32, because scroll bar 33 and the steering gear 11 on fixed support 1 mesh, and steering gear 11 itself can not rotate, thereby scroll bar 33 is while rotating, scroll bar 33 can drive steering hardware 3 by steering gear 11 and rotate, make the minute surface body 2 that is connected in steering hardware 3 deflect to a fixed angle left, thereby make steerman can see through the deflection left of minute surface body 2 and obtain that vehicle turns left or required field-of-view angle during lane change left.

In addition, when steerman beats that the right-hand rotation indicator prepare to be turned right or to the right during lane change, described control circuit 4 detects the right lamp and lights produced pulse wave, drive servomotor 31 actions, servomotor 31 drives scroll bar 33 by gear cluster 32 and rotates, and now, scroll bar 33 drives steering hardware 3 by steering gear 11 and rotates, make the minute surface body 2 that is connected in steering hardware 3 deflect to a fixed angle to the right, thereby steerman is obtained turn right or required field-of-view angle during lane change to the right.

And, when vehicle completes left-hand rotation, right-hand rotation or lane change action, after steerman is turned off indicator, described control circuit 4 is opened the pulse wave produced less than left and right indicator because of detecting, and then drive servomotor 31 that minute surface body 2 is gone back to original position.

Therefore, rear-view mirror system provided by the utility model, can be when Vehicle Driving Cycle by the signal of indicator that steerman is opened, differentiate and drive that human desires turns to or the direction of lane change, and then adjust the back mirror angle, can avoid because of turn to or during lane change the limited steerman that causes in the angle visual field can't grasp the rear view of vehicle situation.Moreover, due to rear-view mirror system provided by the utility model, at rear-vision mirror face, do not do any change, when therefore steerman is observed the rear view of vehicle situation by back mirror, do not have the situation that causes in the steerman startup procedure identification of must diverting one's attention because the image of the image that the convex catadioptre presents and back mirror overlaps and occur.

Obviously, those skilled in the art can carry out various changes and modification and not break away from spirit and scope of the present utility model the utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model also is intended to comprise these changes and modification interior.
