Abstract
The utility model relates to a manual folding mechanism for a rear-viewing mirror, which is designed for sealing, designing and protecting a folding mechanism. The utility model comprises a movable mirror shell and a reflective mirror unit and is characterized in that an insertion piece which is integral with the mirror shell is provided with a hollow cavity, and a threaded rod is arranged in the hollow cavity. The upper end of the threaded rod is provided with a nut, and the lower end of the threaded rod is sheathed with an upper steel ball base which fixes the threaded rod. A spring is arranged between the nut and the upper steel ball base of the threaded rod, and correspondingly, a fixed bearing base is provided with a lower steel ball base which is sheathed on the threaded rod. A joint end surface between the upper and the lower steel ball bases is provided with a plurality of upper and lower craters, and steel balls are inlaid in the craters. Simultaneously, the mirror shell, the threaded rod and fixed base are provided with threading holes for the threading of electrical wires. The utility model has the advantages of good protection effect, light weight and high safety, and is suitable for the popularization and the application of vehicle.
Description
The utility model relates to a kind of automobile rearview mirror manual folding machine structure technical field.
Along with the auto trade development, vehicular spare parts back mirror sales volume increases gradually, generally uses back mirror that following deficiency is arranged usually in the market, and fold mechanism can be seen in the mirror shell, not only influences attractive in appearance but also be subjected to extraneous corrosion easily, reduces service life; The space is narrow and small in the mirror shell, causes initial tension of spring to regulate the test difficulty, causes that the dynamics weight differs when folding, and also influence is used; It is more to water foundry goods, and back mirror is heavier, is that 94193115.3 Chinese patent " overcomes the mirror assembly that the backspring bias voltage enters the position of folding back with power " and be exactly relatively representative type example as application number.
The purpose of this utility model is to provide a kind of fold mechanism base closed, protects fold mechanism preferably, can regulate the back mirror manual folding machine structure of folding dynamics again.
The technical solution of the utility model is to realize like this.This back mirror manual folding machine structure includes fixed mounting base, movable mirror shell, light deflector unit and is installed in this movable mirror shell, it is characterized in that being integral inserts with the mirror shell has cavity, built-in screw rod, there is nut the screw rod upper end, the screw rod lower end is with upper steel ball seat screw rod is fixed, prop up between screw rod upper nut and the upper steel ball seat spring is arranged, fixed mounting base is equipped with the lower steel ball seat that is placed on the screw rod accordingly, the applying end face has a plurality of crater up and down between the last lower steel ball seat, embedded steel ball, mirror shell, screw rod, fixed mounting base have the through wires hole that supply line passes simultaneously.
Back mirror manual folding machine structure advantage of the present utility model has: (1) except necessary through wires hole, mechanism's base closed is protected fold mechanism well; (2) because the degree that screw rod hangs tight the nut compression spring is in the adjustment of mirror shell external application dynamometric device, so control the suitable unanimity of dynamics when making the back mirror of producing folding more conveniently; (3) use plastics inserts fixed fold mechanism, alleviated back mirror weight to a great extent; (4) safety is better, has projection and limited impression between the last lower steel ball seat binding face, can make mirror shell crash-avoidance car body; (5) power lead of electric direction varying device passes from the screw rod endoporus, and the support counterbore seals with vinyl cover, not only safety but also effectively utilize the space.
Description of drawings:
Fig. 1. back mirror manual folding machine structure local structure cutaway view;
Below in conjunction with description of drawings embodiment of the present utility model is further described.
As shown in the figure, this back mirror manual folding machine structure includes fixed mounting base 9, movable mirror shell 6, the light deflector unit is installed in this movable mirror shell, be integral plastics inserts 1 with the mirror shell and have cavity with built-in fold mechanism form fit, a built-in screw rod 2, there is nut 3 the screw rod upper end, the screw rod lower end is with upper steel ball seat 5 screw rod is fixed in the cavity, and upper steel ball seat top is made vast sky heart cylinder and is become spring perch, there is spring 4 on the top between nut and the spring perch, fixed mounting base is provided with the lower steel ball seat 8 that is placed on the screw rod accordingly, the applying end face has a plurality of crater up and down between the last lower steel ball seat, and on circumference, be 90 ° uniform, embedded steel ball 7, the crater, top is shallower than hemisphere, steel ball is climbed on the plane, the crater, lower part is deeper than hemisphere, fixed mounting base is installed the embedded plastic cover plate 10 of counterbore at screw rod, while mirror shell, screw rod, fixed mounting base has through wires hole, pass electric direction varying device electric power connection line 11, upper steel ball seat is shaped on projection in applying end face periphery, and corresponding lower steel ball seat has spacing part annular groove on the applying end face.
When needs are folding, pull the mirror shell, the component that upper steel ball seat is made progress when the steel ball cambered surface is during greater than the deflection of spring power of pretension, top mirror shell integral body is lifted, steel ball break away from the upper steel ball seat crater and and plane contact, the mirror shell just can rotate like a cork, steel ball enters the i.e. folding position of need, crater again after 90 ° when turning over, when the mirror shell resetted, situation was the same.
