[0027] A retaining spring 34 and a spring 35 are provided on the rotating shaft 33 in the electric folding movement body 31; the retaining spring 34 is clamped at the end of the rotating shaft 33; the spring 35 is sleeved on the outside of the rotating shaft 34; one end of the spring 35 acts on the end surface of the retaining spring 34, and the other end acts on the end surface of the rotating shaft head 32;

[0028] A retaining ring 36 is provided between the rotating shaft head 32 and the rotating shaft 33; the retaining ring 36 is embedded in the rotating shaft 33, and part of the retaining ring 36 passes through the outside of the rotating shaft 33; the retaining ring 36 on the outside of the rotating shaft 33 is clamped on the end face of the rotating shaft head 32; three clamping bodies 331 are provided at the end of the rotating shaft 33 outside the electric folding movement body 31.

[0029] From the above description, it can be seen that the beneficial effects of the present invention are: the automobile exterior rearview mirror realizes rapid disassembly and assembly between the mirror substrate 1 and the mirror base 2 through the electric folding movement 3; the structure of the electric folding movement 3 is simpler, which not only ensures the rotation operation between the mirror substrate 1 and the mirror base 2, but also facilitates subsequent maintenance operations and reduces maintenance time; at the same time, the mirror substrate or the mirror base can be replaced separately, saving maintenance costs.

[0030] Furthermore, a clamping seat 21 is provided on the upper surface of the mirror base 2; three bosses 211 and grooves 212 arranged alternately are evenly provided on the upper end surface of the clamping seat 21; three first square grooves 213, second square grooves 214 and third square grooves 215 are evenly provided on the inner hole end surface of the clamping seat 21; the first square groove 213 is vertically arranged, and the first square groove 213 extends downward from the upper end surface of the clamping seat 21; the second square groove 214 is horizontally arranged, and the second square groove 214 is connected with the first square groove 213; the third square groove 215 is vertically arranged, and the third square groove 215 is connected with the second square 214.

[0031] From the above description, it can be seen that the boss 211 and the groove 212 arranged on the upper end surface of the clamping seat 21 correspond to the structure of the shaft head 32; the connection position relationship between the card body 331 and the clamping seat 21 can be determined through the relative positions of the boss 211, the groove 212 and the shaft head 22; the first square groove 213 guides the card body 331, thereby limiting the downward placement of the shaft 33 along a fixed direction; the second square groove 214 connects the first square groove 213 and the third square groove 215, so that the shaft 33 can rotate a certain angle, and then the card body 331 can enter directly below the third square groove 215; the card body 331 is clamped in the third square groove 215, thereby realizing the function of connecting the shaft 33 with the clamping seat 21.

[0032] Furthermore, the card body 331 is a square structure; and rounded transitions are provided between the end faces of the card body 331 .

[0033] From the above description, it can be seen that the square structure corresponds to the structures of the first square groove 213 , the second square groove 214 , and the third square groove 215 ; the provision of a chamfered transition is beneficial to the connection between the card body 331 and the card connector 21 .

[0034] Furthermore, an arc-shaped groove 321 is provided on the end surface of the inner hole of the rotating shaft head 32 ; the opening of the arc-shaped groove 321 is communicated with the inner hole of the rotating shaft head 32 .

[0035] It can be known from the above description that the arc groove 321 is used to limit the position of the retaining ring 36 in the rotating shaft head 32 , so that the rotating shaft 33 and the rotating shaft head 32 are relatively stationary.

[0036] Furthermore, the rotating shaft 33 is a high-strength metal tube shaft; square holes 332 are symmetrically arranged on the side of the rotating shaft 33; and the square holes 332 are through holes.

[0037] From the above description, it can be seen that the shaft is made of high-strength metal material and a stamping process is adopted, so that the shaft 33 has high strength, strong deformation resistance, and good fatigue resistance; the square hole 332 is used to install the retaining ring 36.

[0038] Furthermore, the retaining ring 36 is a retaining ring formed by heat treatment of stainless steel or manganese steel spring wire.

[0039] It can be seen from the above description that the retaining ring 36 has a high elastic deformation capacity and good fatigue resistance.

[0040] Furthermore, the retaining ring 36 is an open retaining ring, and the end surface of the retaining ring 36 is symmetrically provided with a hanging ear 361; the structural dimension of the hanging ear 361 is the same as the structural dimension of the arc groove 321.

[0041] From the above description, it can be known that the open retaining ring makes the retaining ring 36 have a certain elasticity; the ear 361 is arranged to be the same as the arc groove 321 in order to better limit the relative position of the rotating shaft 33 in the rotating shaft head 32 through the retaining ring 36.

[0042] Furthermore, the hanging ear 361 is an arc-shaped structure, and an opening of the hanging ear 361 is communicated with the retaining ring 36 .

[0043] It can be seen from the above description that the arc-shaped structure enables the ear 361 to have a better deformation ability when the retaining ring 36 is subjected to force, and is smoother during the deformation process.

[0044] The invention is applied to the connection structure of the automobile exterior rearview mirror and is used for connecting the mirror substrate and the mirror base.

[0049] A retaining ring 36 is provided between the rotating shaft head 32 and the rotating shaft 33; the retaining ring 36 is inserted into the rotating shaft 33, and a part of the retaining ring 36 extends to the outside of the rotating shaft 33; the retaining ring 36 on the outside of the rotating shaft 33 is clamped on the end face of the rotating shaft head 32; three clamping bodies 331 are provided at the end of the rotating shaft 33 outside the electric folding movement body 31;

[0050] The upper surface of the mirror base 2 is provided with a clamping seat 21; the upper end surface of the clamping seat 21 is evenly provided with three bosses 211 and grooves 212 arranged alternately; the inner hole end surface of the clamping seat 21 is evenly provided with three first square grooves 213, second square grooves 214, and third rectangular grooves 215; the first square groove 213 is vertically arranged, and the first square groove 213 extends downward from the upper end surface of the clamping seat 21; the second square groove 214 is horizontally arranged, and the second square groove 214 is connected with the first square groove 213; the third rectangular groove 215 is vertically arranged, and the third rectangular groove 215 is connected with the second square 214;

[0051] The card body 331 is a square structure; a rounded transition is provided between each end surface of the card body 331;

[0052] An arc groove 321 is provided on the inner hole end surface of the rotating shaft head 32; the opening of the arc groove 321 is communicated with the inner hole of the rotating shaft head 32;

[0053] The rotating shaft 33 is a high-strength metal tube shaft; square holes 332 are symmetrically arranged on the side of the rotating shaft 33; the square holes 332 are through holes;

[0054] The retaining ring 36 is a retaining ring formed by heat treatment of stainless steel or manganese steel spring wire;

[0055] The retaining ring 36 is an open retaining ring, and a hanging ear 361 is symmetrically provided on the end surface of the retaining ring 36; the structural dimensions of the hanging ear 361 are the same as the structural dimensions of the arc groove 321;

[0056] The hanging ear 361 is an arc-shaped structure, and an opening of the hanging ear 361 is communicated with the retaining ring 36 .

[0057] The working principle of the present invention is as follows: before installation, the three card bodies 331 on the rotating shaft 33 are pre-assembled downward along the first square groove 213; until the end face on the rotating shaft head 32 is in contact with the boss 211 on the clamping seat 21; the electric folding movement body 31 is rotated counterclockwise along the axis of the rotating shaft 33 until the card body 331 is in contact with the side end face of the second square groove 214; since the card body 331 is limited by the second square groove 214, the rotating shaft 33 can no longer rotate.

[0058] Continue to rotate the electric folding mechanism body 31. Since the shaft 33 cannot rotate, the ear 361 of the retaining ring 36 assembled in the shaft 33 undergoes radial deformation along the arc groove 321 of the shaft head 32. When the electric folding mechanism body 31 rotates a certain angle (usually 6-12 degrees), the ear 361 of the retaining ring 36 completely disengages from the arc groove 321, thereby driving the shaft 33 to be tightened upward, so that the card body 331 is clamped in the third-party groove 215.

[0059] At the same time, since the rotating shaft 33 moves a distance into the electric folding movement body 31, the spring 35 is compressed, and when the retaining ring 36 completely leaves the arc groove 321, the electric folding movement body 31 is quickly pulled downward, so that the boss 211 and the groove 212 of the clamping seat 21 fit with the structure on the rotating shaft head 32. At this point, the electric folding movement 3 and the mirror base 2 are quickly installed.

[0060] When the electric folding movement 3 needs to be removed from the mirror base 2, the electric folding movement 3 is pulled upward along the axis of the rotating shaft 33 and rotated a certain angle, so that the ear 361 on the retaining ring 36 returns to the arc groove 321 of the rotating shaft head 32; at this time, the card body 331 is separated from the third square groove 215 and enters the second square groove 214; the electric folding movement 3 is rotated clockwise by a certain angle (usually 6-12 degrees); the electric folding movement 3 can be smoothly taken out from the mirror base 2.

[0061] In summary, the automobile exterior rearview mirror uses an electric folding mechanism to achieve quick disassembly and assembly between the mirror substrate and the mirror base; the electric folding mechanism has a simpler structure, which not only ensures the rotation operation between the mirror substrate and the mirror base, but also facilitates subsequent maintenance operations and reduces maintenance time; at the same time, the mirror substrate or the mirror base can be replaced separately, saving maintenance costs.

[0062] In addition, the structural design of the card seat can not only ensure that the electric folding movement can be disassembled and connected to the mirror base more smoothly, but also ensure the stability of the electric folding movement after being connected to the mirror base.
