The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 4, an exterior mirror folding mechanism includes:

the base plate 1, the base plate 1 is set up in the outside rear-view mirror, there are through holes on the base plate 1;

the rotating shaft 2 is arranged at the through hole, the rotating shaft 2 rotates by taking the length extending direction as an axis, and one end of the rotating shaft 2 is attached to the substrate 1;

the elastic body 3, the elastic body 3 compresses the base plate 1 and the rotating shaft 2;

base plate 1 is provided with first recess 11 in the one end of laminating with pivot 2, and pivot 2 is provided with boss 21 in the one end of laminating with base plate 1, and boss 21 mutually supports with first recess 11, and pivot 2 drives base plate 1 and rotates.

Through setting up base plate 1, pivot 2 and elastomer 3, base plate 1 lies in the one end of 2 laminatings of pivot to be provided with first recess 11, and the one end that pivot 2 lies in the base laminating is provided with boss 21, and boss 21 and recess mutually support, and pivot 2 drive base plate 1 when rotatory rotates to make outside rear-view mirror take place to fold, simple structure is reliable, is difficult for breaking down, and life is high, has increased the utility model discloses a practicality and reliability.

Preferably, in the above embodiment, there are three bosses 21, and the three bosses 21 are provided at equal intervals.

Through setting up boss 21 to be three, and equidistant setting between the three boss 21 for it is more stable to mutually support between boss 21 and the first recess 11, even cooperation between one of them boss 21 and the first recess 11 goes wrong, other boss 21 can also form the cooperation each other with first recess 11, continues to provide stable cooperation, thereby it is rotatory to continue to drive base plate 1 when making pivot 2 rotatory, realizes the folding of outside rear-view mirror, has increased the utility model discloses a practicality and reliability.

As a preference of the above embodiment, the length of the boss 21 at the end far from the rotation shaft 2 is longer than that at the end near the rotation shaft 2.

Because the transmission of carrying out the rotation between pivot 2 and the base plate 1, so the required rotatory distance of one end when rotatory of pivot 2 is kept away from to boss 21 is more, so be greater than the one end of being close to pivot 2 with the length of boss 21 in the one end of keeping away from pivot 2 for boss 21 both ends are at rotatory in-process, keep unanimous, have increased driven stability, have increased the utility model discloses a practicality and reliability.

Preferably, the two ends of the boss 21 are provided with a slope structure.

Through setting up the inclined plane structure at boss 21 both ends for pivot 2 when assembling with base plate 1, even boss 21 and first recess 11 do not form the cooperation, but under the effect of elastomer 3 and inclined plane structure, when pivot 2 rotates, after pivot 2 rotated certain angle, boss 21 and the automatic cooperation that forms of first recess 11 have increased the utility model discloses a practicality and reliability.

As a preference of the above embodiment, the substrate 1 is further provided with a second groove 12 at one end close to the rotating shaft 2, and the width of the second groove 12 is smaller than that of the first groove 11.

As a preference of the above embodiment, the first groove 11 and the second groove 12 are provided with a slope structure at both ends.

Through being provided with the inclined plane structure at first recess 11 and second recess 12 both ends for pivot 2 when assembling with base plate 1, even boss 21 and first recess 11 do not form the cooperation, but under the effect of elastomer 3 and inclined plane structure, when pivot 2 rotates, after pivot 2 rotated certain angle, boss 21 and the automatic cooperation that forms of first recess 11 have increased the utility model discloses a practicality and reliability.

Preferably, the elastic body 3 is a compression spring.

Set up elastomer 3 into compression spring, it is simple reliable, increased the utility model discloses a practicality.

Preferably, the rotating shaft 2 is provided with a limiting structure 4 at the other end, and the limiting structure 4 limits the compression spring to move along the length extending direction of the rotating shaft 2.

Through setting up limit structure 4, restriction compression spring removes along 2 length extending direction of pivot to make compression spring extrude pivot 2 and base plate 1, make pivot 2 paste tightly with pivot 2, thereby ensure mutually supporting between arch and the first recess 11, can drive base plate 1 when pivot 2 is rotatory, thereby realize the folding of outside rear-view mirror, increased the utility model discloses a practicality and reliability.

As a preferred embodiment, the other end of the rotating shaft 2 is provided with a clamping groove 22, the limiting structure 4 is a pressing ring 41 and a clamping spring 42, and the clamping spring 42 is arranged in the clamping groove 22.

Through setting up draw-in groove 22 at the 2 other ends of pivot, limit structure 4 is clamping ring 41 and jump ring 42, and clamping ring 41 contacts with compression spring, and jump ring 42 sets up in draw-in groove 22, and the length extending direction of draw-in groove 22 perpendicular to pivot 2, jump ring 42 insert along draw-in groove 22, compress tightly clamping ring 41 and compression spring, realize having increased compression spring's limit function the utility model discloses a practicality and reliability.

As a preference of the above embodiment, the pressing ring 41 is provided with a retaining ring 411 at an end away from the compression spring, and the circlip 42 is located in the retaining ring 411.

Be provided with retaining ring 411 in the one end of keeping away from compression spring through clamping ring 41, jump ring 42 is located retaining ring 411, because the length extending direction of draw-in groove 22 perpendicular to pivot 2, retaining ring 411 is on a parallel with the length extending direction of pivot 2, clamping ring 41 is under compression spring's effect, be exerted a power that is on a parallel with 2 length extending direction of pivot, and the length extending direction of draw-in groove 22 perpendicular to pivot 2, jump ring 42 is located retaining ring 411 again, make limit structure 4 form the structure of a auto-lock, form stable cooperation under the effect of not having the external force, restricted the displacement with compression spring, thereby guaranteed pivot 2 and base plate 1's complex stability, increased the utility model discloses a practicality and reliability.
