It plays the role of a "second eye", expanding the driver's field of vision. By conducting a folding durability test on the rotation position of the rearview mirror, the quality of the connecting shaft between the rearview mirror and the vehicle body can be evaluated.

Detailed implementation mode

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the protection scope of the present invention.

[0027] The present invention provides an external rearview mirror rotation position detection mechanism as shown in Figures 1 - 5 The external rearview mirror body 11 is rotatably provided with a mounting seat on the external rearview mirror body 11. Since the external rearview mirror body 11 reflects the conditions behind, on the side and below the vehicle, enabling the driver to indirectly see clearly the conditions in these positions, it plays the role of a "second eye". Therefore, it is necessary to conduct a folding durability test on its rotation position to evaluate the quality of the connecting shaft between the external rearview mirror body 11 and the mounting seat. However, the existing external rearview mirror rotation position detection mechanism can only conduct a folding durability test on the rotation position of one external rearview mirror body 11 at a time. When detecting the rotation positions of multiple external rearview mirror bodies 11, it takes a long time, resulting in relatively low detection efficiency.

[0028] Therefore, in the present invention, two sets of rotation components are provided at the top of the body 1, and both sets of rotation components are driven to rotate by a power component. Two external rearview mirror bodies 11 are installed on the two sets of rotation components. By driving the two rotation components to rotate with one power component, the external rearview mirror body 11 is driven to reciprocate, thereby conducting a folding durability test on its rotation position until the connection between the external rearview mirror body 11 and the mounting seat is damaged or the number of rotations reaches the set requirements.

[0029] Specifically, the power component includes a motor 2 and a support block. Both the motor 2 and the support block are fixedly arranged inside the body 1. The rotating shaft end of the motor 2 is fixedly connected to a reciprocating lead screw 3. The reciprocating lead screw 3 is rotatably connected to the support block. A movable block 4 is threadedly connected to the outer circumference of the reciprocating lead screw 3. Both sides of the movable block 4 are fixedly provided with racks 5. The movable block 4 and the racks 5 are both movably attached to the inner wall of the body 1. One side of the rack 5 away from the movable block 4 is meshed with a gear 6. The gear 6 is rotatably connected to the body 1 through a bearing. After the outer rearview mirror body 11 is installed, the motor 2 is started to drive the reciprocating lead screw 3 to rotate, driving the movable block 4 to reciprocate on the reciprocating lead screw 3, thereby driving the racks 5 on both sides of the movable block 4 to reciprocate, and finally driving the two gears 6 to reciprocally rotate in opposite directions. Since the rotating assembly is arranged on the gear 6, the two sets of rotating assemblies are driven to reciprocally rotate in opposite directions, and a synchronous folding durability test is carried out on the rotating positions of the two outer rearview mirror bodies 11, thus avoiding the problem that the traditional outer rearview mirror rotation position detection mechanism can only perform a folding durability test on the rotating position of one outer rearview mirror body 11 each time. When detecting the rotating positions of multiple outer rearview mirror bodies 11, it takes a long time, resulting in relatively low detection efficiency.

[0030] Further, a clamping assembly for clamping the outer rearview mirror body 11 is arranged on the rotating assembly, and a fixing assembly for installing the outer rearview mirror body 11 is also arranged on the body 1. Among them, the rotating assembly includes a driven rod 7. The driven rod 7 is fixedly arranged in the middle of the top of the gear 6. One end of the driven rod 7 that movably extends out of the upper surface of the body 1 is fixedly provided with a cantilever plate 8. The clamping assembly is arranged at the end of the cantilever plate 8 away from the driven rod 7. The clamping assembly includes two limiting rods 9. An adjusting hole 12 is opened on the cantilever plate 8. One of the limiting rods 9 is fixedly connected to the cantilever plate 8. A threaded end is fixedly arranged at the top of the other limiting rod 9. A limiting plate 13 is fixedly arranged on the outer circumference of the bottom of the threaded end. A fastening screw 14 is threadedly connected to the end of the threaded end that movably extends out of the adjusting hole 12. The outer rearview mirror body 11 is movably attached between the two limiting rods 9.

[0031] Specifically, the outer rearview mirror body 11 is placed between the two limiting rods 9. The position of one of the limiting rods 9 on the adjusting hole 12 is adjusted so that the two limiting rods 9 clamp the outer rearview mirror body 11. Then the fastening screw 14 is tightened on the threaded end, and with the cooperation of the limiting plate 13, the position of this limiting rod 9 is fixed, facilitating the clamping of outer rearview mirror bodies 11 with different thickness specifications.

[0032] In order to prevent the connection shaft between the outer rearview mirror body 11 and the mounting seat from loosening under the vibration of the device and affecting the detection result, a shock-absorbing sleeve 10 is sleeved on the outer circumference of the limiting rod 9. Through the installation of the shock-absorbing sleeve 10, the vibration feeling brought to the connection shaft by the reciprocating rotation of the outer rearview mirror body 11 is reduced.

[0033] Further, the fixing component includes support plates 15. There are two support plates 15, which are respectively fixedly installed at both ends of the top of the machine body 1. On the surfaces of the two support plates 15 facing each other, electric push rods 17 are fixedly arranged. The telescopic ends of the electric push rods 17 movably pass through the two side surfaces of the support plates 15 and are fixedly connected with pressing plates 18. There are two electric push rods 17 symmetrically distributed about the center line of the support plate 15. The driven rod 7 is located exactly in the middle of the two electric push rods 17. Insert the mounting seat of the external mirror body 11 from bottom to top into the middle of the support plate 15 and the pressing plate 18. Start the electric push rod 17 to make the pressing plate 18 displace inward, so as to press the mounting seat of the external mirror body 11 against the support plate 15. Since the two surfaces of the mounting seat are respectively in movable contact with the pressing plate 18 and the support plate 15, it is convenient for the disassembly and installation of the external mirror body 11, and the mounting seats of different sizes of the external mirror body 11 can be pressed and fixed, improving the applicability of the device.

[0034] Further, there is a gap between the support plate 15 and the cantilever plate 8. Two connecting blocks 16 are fixedly arranged on the surface of the support plate 15 close to the electric push rod 17. The connecting blocks 16 and the driven rod 7 are rotationally connected through bearings. By installing the two connecting blocks 16, the rotational stability of the driven rod 7 is improved.
