Abstract

The utility model relates to an electric wiper of a vehicle rear vision mirror. The power outputted by a motor is used for driving a square rod to rotate towards the left and the right with 120 DEG through a group of connecting rods. The square rod drives a transmission rod, and the other end of the transmission rod drives a wiper handle through a universal joint cross. The wiper handle rotates from left to right, which leads the wiper to move back-and-forth on the surface of a rear vision mirror. The surface of the rear vision mirror is cleaned.

Description

Electric wiper of vehicle rear vision mirror

This creation system is relevant for a kind of electronic rain brush of automobile rearview mirror.

Pressing automobile rearview mirror, mainly is to make chaufeur in when driving, can see the motoring condition of front vehicle clearly, knows whether operation such as convertible track or turning to declare.So this back mirror is played the part of to take care of on traffic safety and is wanted the role.

The framework upper limb of automobile rearview mirror is comparatively outstanding so that hide rain, but sees the rear vehicle condition shown in the minute surface for ease of chaufeur, covers minute surface so this framework upper limb also can not excessively be given prominence to.So, the automobile rearview mirror framework of present stage, the actual rainwater that can't prevent is built-up on the minute surface, so that causes the afunction of back mirror.

Huge when the force of rain, or when travelling in rainy night, the function of this back mirror completely loses, even the force of rain is little, chaufeur is for protecting traffic safety, and usually when vehicle suspends (when waiting for green light) falls the Qianmen vehicle window, wipes with cloth and tries back mirror.When wanting the wiping right rear, chaufeur must extend body to the right, and is promptly bothersome tiring again, and often has green light bright, still takes place not as good as the situation that starts.Because when above-mentioned chaufeur Chang Bixu utilizes the time-out that travels, wipe the behavior of examination back mirror, this back mirror should possess rain brush in fact, so that clean minute surface at any time.

The applicant feels the important of automobile rearview mirror deeply, and being provides a kind of rear-view mirror electric rain brush, enables in time to clean the dirty dirt and the globule on the back mirror, keeping the peace and quiet of minute surface, and can give full play to its function.

This creation system is with electrical motor coupler link group, and with transmission one square pole left-right rotation, rotational angle is 120 °.This square leverage transmission one drive link, this drive link transmission one windshield wiper handle, this windshield wiper handle can drive rain brush and make reciprocating action.

Architectural feature of the present utility model and function are described in detail with reference to following accompanying drawing:

Fig. 1 is the constructional drawing of this creation.

The scheme drawing that Fig. 2, Fig. 3, Fig. 4 turn left and right for this creation square pole work.

Fig. 5 and Fig. 6 are the scheme drawing of cross universal joint.

Fig. 7 is the rain brush view of this creation.

Fig. 8 is the A-A semi-sictional view enlarged drawing of this creation rain brush.

Fig. 9 is the External view of rain brush on back mirror of this creation.

See also the constructional drawing of shown in Figure 1 creation, the main system of this creation is by electrical motor (1) and reducing gearbox (2) outputting power, and the linkage rod group that is constituted by three connecting rods (21) (22) (23), transmission one square pole (3) turns left and right shown in Fig. 2,3,4.One end of this square pole (3) is provided with the drive link (4) of helical wheel (31) with another helical wheel of transmission (41).One end of this drive link (4) turns left and right with universal joint cross (5) transmission one windshield wiper handle (6).This windshield wiper handle (6) is the bar (61) that is provided with two tool retractilities, and the end system and the rain brush permanent seat (7) of this two bar (61) articulate.Rain brush permanent seat (7) is to be subjected to its moving direction of two groups of guide grooves (81) correcting respectively.The two ends system of this rain brush (9) is separately fixed on the two rain brush permanent seats (7).When windshield wiper handle (6) when turning left and right, can drive rain brush (9) and go up reciprocating at minute surface (82).

The drive link of this creation (4) mainly is being convenient to the usefulness of installation, so that entire mechanism can cooperate the car body setting.Above-mentioned universal joint cross (5) ties up to pivoting point central authorities and is provided with a square block (51) as Fig. 5, shown in Figure 6, so that two tip nodes can articulate the relative square block in center (51) and rotate, can reach the effect of universal transmission.For this reason, when chaufeur was adjusted the angle of back mirror, this universal joint cross (5) can guarantee the transmission of power.

Two bars (61) of above-mentioned windshield wiper handle (6), system wears bar (63) in by an outer tube (62), and be separately fixed on outer tube (62) and the interior bar (63) with (64) two incompressible on a spring, make interior bar (63) have the function of automatic elongation or contraction, so that rain brush (9) is in moving, bar (61) length changes.

In above-mentioned, two guide brackets (7) of the solid rain brush (9) of frame are subjected to the restriction of guide groove (81), are reciprocating according to certain track.So rain brush (9) is to go up reciprocating at minute surface (82).

In sum, the mechanism of this creation to simplify makes back mirror can obtain the purpose of the clear minute surface of brush (82) of electronic rain brush (9), has the practicality of promoting effect in fact.

Claims

1, a kind of electronic rain brush of automobile rearview mirror is primarily characterized in that: by a linkage rod group power transmission one square pole of electrical motor output is done turning left and right of suitable moving angle; This square pole is borrowed helical wheel transmission one drive link, and this drive link is with universal joint cross transmission one windshield wiper handle, and this windshield wiper handle is provided with the bar of two tool retractilities, and the system of end in addition of this two bar articulates with the rain brush permanent seat; This two rain brush permanent seat system is the two ends of rain brush fixedly, so that rain brush is pressed close to minute surface, and are subjected to its moving direction of rain guide groove correcting respectively in two rain brush permanent seats; The power of exporting when electrical motor is when transmission turns left and right windshield wiper handle, and it is reciprocating on minute surface to drive rain brush.

2, the electronic rain brush of automobile rearview mirror as claimed in claim 1 is characterized in that, the bar of windshield wiper handle two tool retractilities is by wearing bar in the outer tube, and with the two ends of an incompressible spring respectively fixedly on outer tube and the interior bar.
