[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 2The utility model provides an embodiment: a car rearview mirror with a wiper structure, comprising a housing 1, a mounting frame 2 is arranged on the top of the housing 1, and two mounting frames 2 are fixed to both sides of the car by bolt structures. A mounting rod 3 is fixedly connected to the bottom of the mounting frame 2, and a connecting assembly is installed on the top of the housing 1. The mounting rod 3 is restricted to the top of the housing 1 by the connecting assembly, and then the mounting frame 2 and the housing 1 are connected to fix the rearview mirror on the mounting frame 2. A mirror surface 4 is installed at the front of the housing 1, and the road conditions behind the side of the vehicle can be clearly seen through the reflection of the mirror surface 4. Two fixing frames 5 are fixedly connected to the top edge of the shell 1, and a base frame 6 is fixedly connected to the bottom of the shell 1. A motor 9 is fixedly connected to the top of one of the fixing frames 5, a threaded rod 7 is fixedly connected to the output end of the motor 9, and a mounting frame 10 is threadedly connected to the outer periphery of the threaded rod 7. A sliding rod 8 is fixedly connected between the other fixing frame 5 and the base frame 6. The threaded rod 7 can be driven to rotate by starting the motor 9, and the mounting frame 10 can be moved by the rotation of the threaded rod 7. The mounting frame 10 can move up and down under the drive of the threaded rod 7 through the limitation of the sliding rod 8.

[0032] Reference Figure 1-Figure 3 , a movable block 11 is slidably connected to one side of the interior of the installation frame 10, a scraper 12 is fixedly connected to the side of the movable block 11 close to the housing 1, and a plurality of springs 13 are arranged on the other side of the interior of the installation frame 10. The movable block 11 and the scraper 12 are driven to move up and down by the movement of the installation frame 10, so that the scraper 12 can scrape the rainwater on the mirror surface 4. At the same time, when the contact wear of the scraper 12 and the mirror surface 4 is serious, the spring 13 will squeeze the movable block 11, and then the movable block 11 and the scraper 12 will be tightly pressed against the direction of the mirror surface 4, ensuring that the scraper 12 can still be in close contact with the mirror surface 4 after wear, ensuring the stability of the scraper 12 rain scraping effect. The two ends of the threaded rod 7 are rotatably connected between the fixed frame 5 and the base frame 6, and the inner edge of the installation frame 10 is slidably connected to the outer periphery of the slide bar 8, so that the threaded rod 7 can stably rotate to drive the installation frame 10 to move, and ensure that the installation frame 10 can maintain linear movement under the limit of the slide bar 8. The movable block 11 is fixedly connected to the limit strips 14 on both the upper and lower sides, and the limit strips 14 are slidably connected to the inside of the installation frame 10. The limit strips 14 can limit the movable block 11 to prevent the spring 13 from pushing the movable block 11 out of the installation frame 10. The spring 13 is located between the inner wall of the installation frame 10 and the movable block 11, and the scraper 12 and the mirror surface 4 are in contact. The movable block 11 is tightly pressed by the spring 13, thereby ensuring that the scraper 12 and the mirror surface 4 can be in close contact.

[0033] Reference Figure 1 , Figure 2 and Figure 4The connection assembly includes a sleeve 15, the outer side of the sleeve 15 is fixedly connected to the top of the housing 1, a positioning pin 16 is slidably connected inside the sleeve 15, a fixing plate 17 is fixedly connected to one side of the outer periphery of the positioning pin 16, the outer side of the fixing plate 17 is slidably connected to the inside of the sleeve 15, a compression spring 18 is arranged on the other side of the outer periphery of the positioning pin 16, and a clamping plate 19 is slidably connected to the top of the sleeve 15. Pull the positioning pin 16 to separate it from the mounting rod 3. At this time, the worker holds the bottom of the housing 1 with one hand and continues to pull the positioning pin 16 outward with the other hand until the positioning pin 16 shrinks into the sleeve 15. At this time, the clamping plate 19 will fall under the action of gravity and insert into the sleeve 15 to block the end of the positioning pin 16. At this time, the worker can release the positioning pin 16 and operate with both hands, which is more convenient. After that, the maintained rearview mirror is installed on the mounting rod 3 again, and the card plate 19 is pushed upward to be separated from the inside of the casing 15. At this time, the compressed compression spring 18 is reset to push the fixing plate 17 and the positioning pin 16 to reset, so that the positioning pin 16 is reinserted into the slot inside the mounting rod 3, and the positioning installation of the rearview mirror is completed. The outer periphery of the mounting rod 3 is slidably connected to the middle side of the top of the shell 1, and the outer periphery of the positioning pin 16 passes through the shell 1 and is inserted into the inside of the mounting rod 3. The mounting rod 3 is restricted inside the shell 1 by the positioning pin 16, ensuring that the shell 1 and the mounting rod 3 can be fixed together. A baffle 20 is arranged on the top of the card plate 19, and the baffle 20 is fixedly connected to the outer wall of the mounting frame 2. The baffle 20 can prevent the card plate 19 from sliding off the top of the casing 15. One end of the compression spring 18 is fixedly connected to the side of the fixing plate 17 away from the mounting rod 3, and the other end of the compression spring 18 is fixedly connected to the inner wall of the sleeve shell 15. The compression spring 18 tightly holds the fixing plate 17 to prevent looseness between the positioning pin 16 and the mounting rod 3.

[0034] Working principle: When it is necessary to scrape the rain on the mirror surface 4, the threaded rod 7 is driven to rotate by starting the motor 9, and then the threaded rod 7 drives the mounting frame 10 to move up and down along the slide bar 8, and the movable block 11 and the scraper 12 are driven up and down by the movement of the mounting frame 10, and then the scraper 12 can scrape the rain on the mirror surface 4. At the same time, when the contact and wear of the scraper 12 and the mirror surface 4 are serious, the spring 13 will squeeze the movable block 11, and then the movable block 11 and the scraper 12 are tightly pressed toward the direction of the mirror surface 4, ensuring that the scraper 12 can still be in close contact with the mirror surface 4 after wear, and ensuring the stability of the rain scraping effect of the scraper 12. When the rearview mirror is damaged and needs to be repaired, the worker only needs to pull the positioning pin 16 to separate it from the mounting rod 3. At this time, the worker holds the bottom of the housing 1 with one hand and continues to pull the positioning pin 16 outward with the other hand until the positioning pin 16 shrinks and enters the inside of the casing 15. At this time, the clamping plate 19 will fall under the action of gravity and insert into the inside of the casing 15, blocking the end of the positioning pin 16. At this time, the worker can loosen the positioning pin 16 and operate with both hands, which is more convenient. After that, the maintained rearview mirror is installed on the mounting rod 3 again, and the clamping plate 19 is pushed upward to separate it from the inside of the casing 15. At this time, the compressed compression spring 18 is reset to push the fixing plate 17 and the positioning pin 16 to reset, so that the positioning pin 16 is reinserted into the slot inside the mounting rod 3, completing the positioning installation of the rearview mirror.
