[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides an on-line detection mechanism for an external rearview mirror as shown in Figures 1-5 Figure 8, which includes a support plate 1 and a bottom plate 3. There are two support plates 1. A conveyor belt 2 is rotatably arranged between the two support plates 1. The bottom plate 3 is fixedly arranged between the two support plates 1 and is in movable contact with the lower surface of the conveyor belt 2. At the middle parts of the tops of the two support plates 1, baffles 4 are fixedly arranged. A detection component is arranged on one of the baffles 4;

[0027] The detection component includes a support rod 9. The support rod 9 is fixedly arranged at the middle part of the top of one of the baffles 4. A lifting groove is fixedly arranged inside the support rod 9. A first motor 10 is fixedly arranged at the bottom of the lifting groove. The rotating shaft of the first motor 10 is fixedly connected with a first lead screw 11. An adjusting plate 12 adapted to the lifting groove is rotatably arranged on the outer circle of the first lead screw 11. One end of the adjusting plate 12 extending out of the lifting groove is rotatably arranged with a rotating plate 13 through a hinge. Hinge seats are fixedly arranged at the bottoms of the rotating plate 13 and the adjusting plate 12. A second electric push rod 14 is rotatably arranged between the two hinge seats. A scale bar 15 is fixedly arranged on the side of the support rod 9. A cantilever rod 16 is fixedly arranged at the top of the support rod 9. An impact block 23 is placed on the top of the rotating plate 13. The impact block 23 is suspended on the cantilever rod 16 through a pull rope 22.

[0028] When this on-line detection mechanism for an external rearview mirror is in use, the external rearview mirror is conveyed to directly below the impact block 23 through the conveyor belt 2. The first motor 10 is started to drive the first lead screw 11 to rotate, so as to drive the adjusting plate 12 to move up and down to different heights, which is convenient for adjusting the impact force of the impact block 23 on the external rearview mirror at different heights. At this time, the second electric push rod 14 is started to make the rotating plate 13 rotate quickly, so that the impact block 23 makes a free fall motion at this height. By recording the scale bar 15 corresponding to the position of the second electric push rod 14, the impact force of the impact block 23 on the external rearview mirror after free fall at this position can be calculated. By using different impact forces for different external rearview mirrors, the fragmentation degree of different external rearview mirrors under different impact forces can be detected, so as to know approximately the range of impact forces that the external rearview mirror can withstand, so that the manufacturer can adjust the relevant parameters of the lens.

[0029] Since the self-weight of the pull rope 22 is negligible and it is not in a taut state throughout the process, the impact force of the impact block 23 is calculated by the way of the free fall of the impact block 23, so as not to cause damage to other components of the device, solving the problem that the existing on-line detection mechanism for external rearview mirrors drives the impact block 23 to impact the external rearview mirror through the telescopic end of the electric push rod, resulting in a large instantaneous reaction force on the electric push rod and easily causing damage to the electric push rod.

[0030] In addition, through the installation of the two baffles 4, the fragments of the broken external rearview mirror are prevented from flying out. At the same time, through the installation of the bottom plate 3, the problem that the elasticity of the conveyor belt 2 affects the detection accuracy is avoided.

[0031] In the present utility model, the conveyor belt 2 rotates at regular intervals to realize the automatic conveying and detection of multiple external rearview mirrors. In order to improve the automation degree of the device and realize the convenience of on-line monitoring, an extension rod 17 is fixedly arranged at one end of the cantilever rod 16 far away from the support rod 9. Cameras 18 are arranged at both ends of the bottom of the extension rod 17. One camera 18 faces the scale bar 15, and the other camera 18 faces the bottom plate 3. Thus, through the installation of the two cameras 18, it is convenient to photograph and read the scale bar 15 corresponding to the height of the second electric push rod 14, and to photograph the fragmentation degree of the corresponding external rearview mirror under the second electric push rod 14 at different positions, which is convenient for remote on-line monitoring and improves the flexibility of the device.

[0032] In order to prevent the external rearview mirror from slipping during impact, first electric push rods 5 are fixedly arranged on the mutually close sides of the two baffles 4. The telescopic ends of the first electric push rods 5 are fixedly connected with clamping plates 6. By starting the first electric push rods 5, the two clamping plates 6 are driven to displace relatively, so as to fix the external rearview mirror.

[0033] In addition, in order to place the external rearview mirror directly below the impact block 23, a photoelectric converter 7 and a laser emitter 8 which are symmetrically distributed about the center line of the bottom plate 3 are respectively fixedly arranged on the mutually close sides of the two baffles 4. The photoelectric converter 7 and the laser emitter 8 are located above the left end of the bottom plate 3. When the external rearview mirror is between the photoelectric converter 7 and the laser emitter 8, the photoelectric converter 7 cannot receive the optical signal of the laser emitter 8. When the external rearview mirror passes through the photoelectric converter 7 and the laser emitter 8, the photoelectric converter 7 receives the optical signal of the laser emitter 8. Thus, through the external controller, the conveyor belt 2 is immediately stopped, and then the first electric push rods 5 are started to drive the two clamping plates 6 to fix the external rearview mirror. At this time, the external rearview mirror is directly below the impact block 23.

[0034] Furthermore, the longitudinal center lines of the bottom plate 3, the baffle 4 and the support rod 9 are in the same vertical plane. Such a setting makes it convenient that after the impact block 23 impacts the external rearview mirror, the reaction force of the external rearview mirror is in the middle of the bottom plate 3, so that the bottom plate 3 will not be unbalanced, bent or tilted.

[0035] After the impact block 23 impacts the outside rearview mirror, it is necessary to lift the impact block 23. Therefore, a chute is fixedly arranged inside the cantilever rod 16. An opening is formed at the bottom of the end of the cantilever rod 16 away from the support rod 9. The opening and the chute communicate with each other. A second lead screw 20 is rotatably arranged in the chute. A movable block 21 is rotatably arranged on the outer ring of the second lead screw 20. The upper surface of the movable block 21 is in movable fit with the chute. One end of the pull rope 22 away from the impact block 23 extends into the chute through the opening and is fixedly connected to the lower surface of the movable block 21. A second motor 19 is fixedly arranged on the side wall of the support rod 9. The rotating shaft of the second motor 19 extends into the chute movably and is fixedly connected to the second lead screw 20.

[0036] Specifically, start the second motor 19 to drive the second lead screw 20 to rotate, drive the movable block 21 to displace in the direction of the second motor 19, pull up the pull rope 22, and thus lift the impact block 23. At this time, the lifting plate 12 is at the lowest position. When the impact block 23 is lifted to the same height as the lifting plate 12, reverse-start the second electric push rod 14 to make the rotating plate 13 rotate back to its original position and fit against the bottom of the impact block 23. At this time, the lifting plate 12 drives the impact block 23 to rise to the height required for the next detection. At the same time, reverse-start the second motor 19 to make the movable block 21 reset, so that during the free fall of the impact block 23, the pull rope 22 is always in a slack state.

[0037] Furthermore, a guide shaft 24 is rotatably arranged at the opening. The pull rope 22 bypasses the guide shaft 24 and is fixedly connected to the movable block 21. Through the installation of the guide shaft 24, the friction between the pull rope 22 and the cantilever rod 16 is avoided. At the same time, when the pull rope 22 pulls up the impact block 23 and the rotating plate 13 rotates, the impact block 23 can be located directly above the rotating plate 13.
