[0012] The beneficial effects of the present application compared with the prior art are:

[0013] 1. When the windshield is damaged by an impact, the force causes the second suction cup to detach downwards along with the fragments. The limiting force on the limiting rod disappears, and the limiting force on the trigger block also disappears. The spring releases its length and pushes the trigger block towards the rotating groove. The trigger block pushes the protrusion, the protrusion pushes the trigger rod, the trigger rod pushes the counterweight, and the counterweight pushes the gear to move towards the gear seat and mesh with it. When the protrusion enters the rotating groove, the counterweight provides weightlessness to the trigger rod, the trigger rod provides weightlessness to the trigger block, and the trigger block provides weightlessness to the protrusion, causing the protrusion to deflect downwards along the rotating groove to the bottom of the groove. At this time, the protrusion rotates clockwise with the trigger rod, the trigger rod rotates clockwise with the gear, the gear rotates counterclockwise with the gear seat, the gear seat rotates counterclockwise with the outer shell, and the outer shell rotates the mirror body downwards. At this time, even if the rearview mirror collides with a person, the mirror body will not face the person because it is rotating downwards, and it will not come into contact with the person because it is rotating downwards. Moreover, even if the mirror body breaks, it will not injure the person.

[0014] 2. When the counterweight deflects downwards, it not only causes the gear to mesh and rotate counterclockwise, but also causes the mirror body to rotate downwards, bringing it to a safe angle. Furthermore, when the top of the gear deflects downwards, it touches the compression part, which in turn compresses the trigger rod to rotate backwards around the hinge seat. According to the linkage structure, this causes the other three trigger rods to rotate backwards around their respective hinge seats. The curved parts of these four trigger rods on the front of the mirror body then deflect outwards along the edge of the outer shell. The restraint on the front of the mirror body is released, and the downward rotation of the mirror body creates a weightless effect. Under the elastic support of the spring seat, it falls downwards from the outer shell. Even if the windshield is shattered in an accident, the mirror body will not only deflect downwards to a safe angle, but even if it moves towards the side of the person with the rearview mirror assembly, it will detach prematurely, preventing injury and further improving safety.

[0027] A limiting hole 16 is arranged on the back of the protrusion 12, the protection mechanism 4 further comprises a top rod 17, one end of the top rod 17 is inserted into the limiting hole 16, and the other end of the top rod 17 is hingedly connected with a first suction disc 18 which is inclined upwards, the first suction disc 18 is adsorbed on the front window of the automobile to position the top rod 17.

[0028] The top rod 17 is a plastic rod made of high-temperature-resistant material.

[0029] A second suction disc 19 is arranged on the back of the universal seat 3.

[0030] In use, the first suction disc 18 (or directly fixed by other fixed ways) is adsorbed on the front window of the automobile, the whole rearview mirror is fixed through the universal seat 3, at the same time, the second suction disc 19 is adsorbed on the front window of the automobile to fix the top rod 17, the other end of the top rod 17 is inserted into the limiting hole 16 of the protrusion 12 to limit the position of the trigger block 6 in the supporting pipe 5, at this moment, the spring 13 is compressed by the trigger block 6, and at this moment, the trigger block 6 is deflected downwards along the straight groove 11 and the trigger rod 9 is deflected downwards with the counterweight 10. Figure 2The shown appearance is far from the rotating groove 8, while the protrusion 12 is also limited in the straight groove 11, when the current window is broken by the impact, the destructive force causes the second suction cup 19 to fall down with the debris, the second suction cup 19 will also fall down with the top rod 17, the limiting force on the top rod 17 disappears, the limiting force on the trigger block 6 also disappears, at this time the spring 13 releases the length, and pushes the trigger block 6 towards the rotating groove 8, the protrusion 12 is pushed by the trigger block 6, the trigger lever 9 is pushed by the protrusion 12, the counterweight 10 is pushed by the trigger lever 9, and the gear 14 is pushed by the counterweight 10 to move to the gear seat 15 and engage on the gear seat 15, when the protrusion 12 enters the rotating groove 8, the counterweight 10 provides weightlessness to the trigger lever 9, the trigger lever 9 provides weightlessness to the trigger block 6, the trigger block 6 provides weightlessness to the protrusion 12, and drives the protrusion 12 to deflect downward along the rotating groove 8 to the groove bottom, at this time the protrusion 12 rotates clockwise with the trigger lever 9, the gear 14 rotates clockwise with the trigger lever 9, the gear seat 15 rotates counterclockwise with the gear 14, the outer shell 1 rotates counterclockwise with the gear seat 15, and the mirror body 2 rotates downward with the outer shell 1, at this time even if the rearview mirror collides with the human body, the mirror body 2 will not face the human body due to the rotation downward, and will not come into contact with the human body due to the rotation downward, and even if the mirror body 2 is broken, it will not hurt the human body.

[0031] As Figure 6 shown, the trigger block 6 is provided with a sunken cavity 20 at one end of the spring 13, the free end of the spring 13 is movably supported in the sunken cavity 20 of the trigger block 6, with the release of the length of the spring 13, the protrusion 12 is not only pushed into the rotating groove 8 by the trigger block 6, but also the trigger block 6 can deflect downward along the rotating groove 8 relative to the support end of the spring 13 by using its sunken cavity 20 when the protrusion 12 loses weight downward.

[0032] In another embodiment, as Figures 2 to 6As shown, a support base 21 is fixed on the back of the outer shell 1. The support base 21 is circular. The gear seats 15 are distributed on the circular surface of the support base 21 in the form of tooth surfaces. Under the support of the support base 21, the gear seats 15 are supported on the path of the gear 14 after displacement and rotation. The bottom end of the counterweight block 10 is provided with a weightlessness groove 22. The weightlessness groove 22 faces the support base 21. The gear 14 is fixed on the weightlessness groove 22. The weightlessness groove 22 is arc-shaped. When the counterweight block 10 rotates downward, in addition to the gear 14 meshing with the gear 14 to rotate, the weightlessness groove 22 also covers the back of the gear 14. The top of the mirror body 2 is movable within the top structure of the outer shell 1, and the bottom of the mirror body 2 is movable within the bottom structure of the outer shell 1. The protective mechanism 4 also includes a hinge seat 23 fixed to the lower back of the outer shell 1, and a limiting rod 24 hinged to the hinge seat 23. One end of the limiting rod 24 hinged to the hinge seat 23 has a pressing part 26 that continues to curve backward, and the pressing part 26 is located on the path of the counterweight 10 rotating in the rearward and downward direction. The other end of the limiting rod 24 has a connecting rod structure 27. The connecting rod structure 27 bends from the back of the outer shell 1 in both upward and downward directions and then bends at the bottom and upper front sides of the outer shell 1 to limit the front side of the mirror body 2. A first tension spring 28 is connected between the limiting rod 24 and the back of the outer shell 1, and a second tension spring 29 is connected between the connecting rod structure 27 and the back of the outer shell 1. A spring seat 25 is filled inside the outer shell 1, and the front end of the spring seat 25 is supported on the back of the mirror body 2. Figure 2 As shown, there are actually four hinge seats 23. These four hinge seats 23 are located at the four corners of the back of the outer casing 1. Each hinge seat 23 is connected to an L-shaped limiting rod 24. The linkage structure 27 is a general term for multiple positions, consisting of a linkage unit connecting the left and right limiting rods 24 and a linkage unit hinged between the upper and lower limiting rods 24. Only the limiting rod 24 on the bottom side of the gear seat 15 is provided with a pressing part 26. When the counterweight 10 moves towards the gear seat 15 and deflects downward due to weightlessness, in addition to causing the gear 14 to mesh with the gear seat 15 and rotate counterclockwise, the top of the counterweight 10 will also collide with the pressing part 26 when it rotates to the bottom, causing the limiting rod 24 to deflect upward. The limiting rod 24 rotates with the connecting rod unit, and the connecting rod unit causes the right limiting rod 24 to deflect upwards and backwards. The upward and backward deflection of the right limiting rod 24 causes the right connecting rod unit to deflect, and the right connecting rod unit causes the upper right limiting rod 24 to deflect upwards and backwards. The upward and backward deflection of the upper right limiting rod 24 causes the upper connecting rod unit to rotate, and the upper connecting rod unit causes the upper left limiting rod 24 to deflect upwards and backwards. At this time, the two upper limiting rods 24 deflect upwards and backwards from the top edge of the outer shell 1, and the two lower limiting rods 24 deflect downwards and backwards from the bottom edge of the outer shell 1. At this time, the bending limiting ends of these four limiting rods 24 on the mirror body 2 will leave the mirror surface, the limiting conditions of the mirror surface are released, and the mirror body 2 freely falls out of the outer shell 1.

[0033] The first tension spring 28 provides a pulling force to the limiting rod 24, the front curved end of which is normally limited on the mirror surface, and the second tension spring 29 on the other side provides a supporting force to the two articulated connecting rod units on the other side, and the two limiting rods 24 on the other side are normally articulated together, and the two connecting rod units have sufficient supporting force to limit the two limiting rods 24 on the other side to their front curved ends, which are also limited on the mirror surface.

[0034] According to the above, when the counterweight 10 deflects downward, not only will the gear 14 mesh with the gear seat 15 and rotate counterclockwise, but also the housing 1 will rotate downward with the mirror body 2, bringing the mirror body 2 to a safe angle (rotating downward), and the top end of the gear 14 will also touch and press the pressing part 26, which will press the limiting rod 24 to rotate backward around the hinge seat 23, and according to the connecting rod structure 27, the other three limiting rods 24 will also rotate backward around the hinge seats 23, and the curved parts of the four limiting rods 24 on the front of the mirror body 2 will deflect outward along the edge of the housing 1, at which time the limiting condition on the front of the mirror body 2 is removed, and the mirror body 2 will rotate downward and lose weight, and under the elastic support of the spring seat 25, it will fall downward from the housing 1. When the front window glass is broken by an accident, not only will the mirror body 2 deflect downward to a safe angle, but even if the mirror body 2 moves with the rearview mirror assembly toward the human side, the mirror body 2 will still fall off in advance and will not cause harm to the human body, further improving the safety factor.

[0035] The above orientation designation does not represent the specific orientation of each component in this embodiment, and this embodiment is only for the convenience of describing the scheme and is described relatively with reference to the orientation in the figure. The actual orientation of each component is determined according to its actual installation and actual use and the orientation description habitually used by those skilled in the art, and this is stated herein.

[0036] The above specific embodiments further detail the purposes, technical solutions, and beneficial effects of the present application. It should be understood that the above description is only a specific embodiment of the present application and does not limit the protection scope of the present application.
