A kind of automobile rearview mirror by-pass cock
Technical field
The utility model relates to a kind of control switch, especially relates to a kind of automobile rearview mirror by-pass cock.
Background technology
Usually, the driver is by the material object behind the rearview mirror observation vehicle body in driving procedure.During the operation rearview mirror, cause phenomenons such as switch loose contact, inefficacy, short circuit under the incorrect situation in position of operation, can cause the angle of rearview mirror can deviation or the poor direction of rotation true, produce harmful effect when moveing backward, even can cause the generation of traffic accident to the driver.
A kind of driven rearview mirrors switch is disclosed as Chinese patent 03230950.3, comprise pedestal, housing, wiring board, left and right sides diverter switch, eyeglass adjusting button, eyeglass is regulated button and is embedded with universal dish composition button assembly, the button assembly contacts with contact on the wiring board by the conductive rubber assembly, left and right sides diverter switch is a toggle switch, left and right sides switching push button is installed on the shift bar of toggle switch, and left and right sides switching push button is installed on the housing.
200720074169.7 1 kinds of rearview mirror switches of Chinese patent, comprise housing, driving lever, circuit board, two slide blocks, cross structure, described driving lever, circuit board, two slide blocks and cross structure all are arranged in the housing, above-mentioned driving lever is located on the circuit board, the circuit board inwall of driving lever and circuit board contact-segment circumferentially offer four grooves, described slide block is positioned on the circuit board, under housing in, described driving lever connects described slide block, cross structure on two slide blocks is realized circuit control with described circuit board, in the driving lever upper edge of driving lever and circuit board contact-segment circumferentially and groove interlock and be provided with four outer rim projections.When driving lever is in zero-span, the outer rim projection is screwed out outside the groove, withstand on the outer inwall of circuit board recess, at this moment, driving lever can not be regulated by four-way, has reduced operational misunderstanding, meets consumers' demand.
The weak point that above-mentioned patent exists is that automobile need be operated on correct position with the rearview mirror by-pass cock, and rearview mirror is run well, and when the operating position is offset, can cause the phenomenon of switch failures such as loose contact, inefficacy, short circuit.
The utility model content
The purpose of this utility model provides a kind of automobile rearview mirror by-pass cock, solves the integrity problem of switch.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of automobile rearview mirror by-pass cock, and comprise button, shell and control the change over switch of left and right rearview mirror motor, be provided with and the adaptive switching circuit plate of Conductive Rubber Blanket in the shell; It is characterized in that: between button and shell, be provided with and be connected support, uniform four bearing pins of described connection support cylindrical, the bearing pin of two symmetries is connected with button activity by two interior supports of button, and the bearing pin of other two symmetries is by two outer supports and the shell flexible connection of shell; Described also adaptive in the enclosure button positions is provided with the fore-set of four activities, and the other end of fore-set is provided with two contacts; The button of described contact contact Conductive Rubber Blanket forms the bridge-type on-off switch; Two outer supports with fore-set are 45.
More reliable for switch work, the center is provided with alignment pin in described button, and in the adaptive alignment pin position of shell mesopore is set, and alignment pin has in the insertion mesopore of free gap.
In order to prevent the misoperation short circuit, spacing muscle is set in the adaptive button positions of described shell.
For the ease of output switching signal, pin terminal formula output interface is set on shell also.
Connect for the ease of installing, the bearing pin termination on the described support cylindrical is provided with chamfering.The two interior two outer terminations of supporting of supporting termination and shell of described button also are provided with chamfering.
Universal joint construction of switch operation principle: connecting support has four bearing pins on it, two bearing pins and button assembling, and two bearing pins and shell assemble in addition; The operator can be in the random angle operation of button, when control button the time not in the 45 position, the same support of button, overturn around shell together, fore-set under the button force part is down moved, the Conductive Rubber Blanket button that drives herein down moves, by the wiring realization on-off function of wiring board.Export the break-make control signal to the rearview mirror motor by pin terminal formula socket assembly.When control button in the 45 position when (being the angular bisector position on the four direction of bat printing sign front, rear, left and right), button rotates around shell, driving support in the process of button pressed downwards down moves, when button pressed downwards and shell reach certain angle, shell has a spacing muscle to carry out spacing, the fore-set of both sides stops down to move, and the button on the Conductive Rubber Blanket does not reach sudden change power, and Conductive Rubber Blanket is not contacted with circuit on the wiring board.The phenomenon that short circuit and loose contact just can not occur; When hand is decontroled, realize resetting of button by the elastic force of Conductive Rubber Blanket button self.
The beneficial effects of the utility model: owing to adopt four-way button touch structure, be equipped with the bridge-type on-off switch of Conductive Rubber Blanket and wiring board formation, combination by this mechanical system realizes break-make, contact is reliable, and can not cause any short circuit, realized the uniqueness of driven rearview mirrors switching function, no matter promptly how to operate, any two phenomenons that the rearview mirror switch is worked simultaneously can not appear, and reliability is splendid.Design by the Conductive Rubber Blanket button realizes good hand feeling and steering force curve.Outward appearance more attractive in appearance, more convenient operation, hommization more
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
