Description
Technical field:
The present invention relates to a kind of steering hardware, specifically is a kind of automobile rear-vision mirror face redirector that can automatic compensation rear-vision mirror face angle.
Background technology:
The float plate that prior art automobile rear-vision mirror face redirector (being also referred to as mirror driver or minute surface commutator on the industry) generally adopts the rack driven mode to drive in the minute surface deflector is rotated; Described rack driven mode refers to, two motors in the minute surface deflector by the motor worm screw make its rotating shaft in full accord with two and independently turbine and worm decelerator be connected, the output shaft of described turbine and worm decelerator is provided with transmission gear, described tooth bar is meshed with transmission gear, and the top of described tooth bar is connected with float plate; When motor operation, described tooth bar can move up and down in vertical direction under the effect of motor and turbine and worm decelerator, rotates thereby drive with its top bonded assembly float plate, reaches the purpose of adjusting the automobile rear-vision mirror face angle.Because the shape of the tooth bar of this type of drive mostly is vertical bar shaped, and the quantity of tooth bar is generally two, therefore adopt the automobile rear-vision mirror face redirector of this rack driven mode to exist to protect that the little strength that promptly keeps minute surface to stagnate of the power of stagnating is smaller, operation inadequately steadily, minute surface is shaken easily and minute surface bearing load ability smaller defect.
Summary of the invention:
The technical problem to be solved in the present invention is, provide a kind of protect the power of stagnating big, operate steadily, minute surface is not easy to shake and minute surface bearing load ability is big automobile rear-vision mirror face redirector.
Technical solution of the present invention is that a kind of automobile rear-vision mirror face redirector with following structure is provided: it comprises base, be located at two motors on the base, with the rotating shaft of described two motors separately two turbine and worm decelerators of bonded assembly, by tooth bar and transmission gear and turbine and worm decelerator bonded assembly float plate and with base bonded assembly motor loam cake; Described base is provided with cross one another first deep-slotted chip breaker and second deep-slotted chip breaker; Described tooth bar is meant that the second semi-circular tooth bar of an oblong radial groove is arranged for first semi-circular tooth bar of arcwall face and bottom at the bottom; Described bottom is that the outer surface on the first semi-circular tooth bar, the two arc limits of arcwall face is provided with first guide rail that can slide on first deep-slotted chip breaker, and wherein the inner surface on an arc limit is provided with first tooth that is meshed with transmission gear; Described bottom has the outer surface on the second semi-circular tooth bar, the two arc limits of an oblong radial groove to be provided with second guide rail that can slide on second deep-slotted chip breaker, and wherein the inner surface on an arc limit is provided with second tooth that is meshed with transmission gear; It is the first semi-circular tooth bar top of arcwall face that described bottom has the second semi-circular tooth bar of an oblong radial groove to intersect across the bottom; The described first semi-circular tooth bar and the second semi-circular tooth bar two free ends separately are connected with described float plate; Described float plate and motor loam cake are rotatably connected.
After adopting above structure, compared with prior art, the present invention has the following advantages: because the bottom is that the second semi-circular tooth bar of an oblong radial groove all can only move back and forth in the deep-slotted chip breaker of guide rail on base on the outer surface on two arc limits separately with it for the first semi-circular tooth bar of arcwall face and bottom among the present invention, therefore the kinematic velocity of two semi-circular tooth bars evenly, steadily and can not suddenly change among the present invention, thereby make with the rotation of semi-circular tooth bar bonded assembly float plate more steadily, be installed in minute surface on the float plate and be not easy shake; In addition and since the present invention adopted two semi-circular tooth bars wherein be provided with on the inner surface on an arc limit separately can with the mode of transmission gear mating teeth, thereby stagnate power and stationarity of guarantor of the present invention all increased greatly; And, each semi-circular tooth bar has two free ends among the present invention, therefore the point of connection of two semi-circular tooth bars and float plate has four, thereby the stationarity that rotate on the same plane that float plate is made up of four points of connection in the present invention is far longer than the stationarity of the same plane rotation that prior art is made up of two point of connection, and the rotation of the minute surface of its load is also more stable, is not easy shake more.
The above-mentioned first semi-circular tooth bar and the second semi-circular tooth bar separately two free ends be connected with described float plate be meant the described first semi-circular tooth bar and the second semi-circular tooth bar separately two free ends be provided with the cylindricality card article, described float plate end face upper edge circumferential edge is provided with the draw-in groove that can block the cylindricality card article, and described motor loam cake circumferential edge is provided with for the described first semi-circular tooth bar and the second semi-circular tooth bar breach that passes of two free ends separately.This structure not only makes dismounting of the present invention more convenient, and because the contact surface of cylindricality card article and draw-in groove is bigger, thereby further increased the stability that float plate is rotated among the present invention.
As a kind of improvement of the present invention, float plate and the motor loam cake end face center that is meant described float plate that is rotatably connected is provided with spherical cavity among the present invention, is connected with a bulb on the described spherical cavity rotationally; The bottom of described bulb is connected on the motor and covers.Because bulb can freely rotate in spherical cavity, thereby make the rotation of float plate among the present invention flexible more, light.
Described turbine and worm decelerator comprises the transmission worm and gear be located on the base, be loaded on motor worm screw on the motor shaft, and transmission gear bonded assembly helical wheel and be located at transmission gear and helical wheel between jump ring; Described transmission worm and gear, motor worm screw and helical wheel are meshing with each other.Noise when adopting turbine and worm decelerator to reduce greatly that the present invention moves.
