[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 3-5 As shown, one embodiment of this utility model provides a wide-angle lens for a car exterior rearview mirror, including a mirror frame 1. A fixing frame 8 is fixedly connected to the inner wall of the mirror frame 1. A connecting frame 3 is provided on the inner wall of the fixing frame 8. A lens body 2 is fixedly connected to the front end of the connecting frame 3. Springs 4 are fixedly connected to both sides of the inner wall of the connecting frame 3. A locking block 5 is fixedly connected to the other end of each spring 4. The outer wall of the locking block 5 is slidably connected to the inner wall of the connecting frame 3. A slot 11 is provided on both sides of the inner wall of the fixing frame 8. One side of the inner wall of the slot 11 is sloped, and one side of the locking block 5 is arc-shaped. Multiple springs 9 are fixedly connected to the inner wall of the fixing frame 8. A push plate 10 is fixedly connected to the other end of each spring 9. Multiple limiting blocks 7 are slidably connected to the inner wall of the connecting frame 3. A limiting groove 6 is provided on the inner wall of each locking block 5. The shape of the limiting block 7 matches the limiting groove 6 for the assembly and disassembly of the lens body 2.

[0027] Specifically, when installing the lens body 2, first flip the connecting frame 3, remove the limiting block 7 from the limiting groove 6, release the limiting of the locking block 5, remove the locking block 5 by spring 4, insert the connecting frame 3 into the fixing frame 8, and after installation, lock the locking block 5 into the locking groove 11 by spring 4, and push the push plate 10 by spring 9, and push the connecting frame 3. Secondly, when the locking block 5 retracts into the fixing frame 8, it will not cause the limiting block 7 to enter the limiting groove 6. By pushing the lens body 2 backward, the lens body 2 can be taken out forward. The tool-free operation avoids damage such as prying, tearing and twisting, and has strong compatibility with multi-material functional lenses and different vehicle models, reducing the threshold of use, saving time and costs, and ensuring driving safety.

[0028] Reference Figure 1 , Figure 2 and Figure 6As shown, a baffle 12 is provided at the front end of the lens body 2. The lens body 2 and the baffle 12 are similar in shape. Mounting frames 13 are fixedly connected to both ends of the baffle 12. Magnets 14 are fixedly connected to the inner walls of the mounting frames 13. Grooves are provided at both ends of the lens frame 1. The length of the mounting frame 13 is equal to the length of the groove. Metal is fixedly connected to the inner walls of the groove for the installation and removal of the baffle 12.

[0029] Specifically, when the lens body 2 needs to be used, simply pull the mounting frame 13 to remove the baffle 12 from the front of the lens body 2. By setting a detachable baffle 12 on the front of the lens body 2, it can block stone impacts, ultraviolet rays or acid rain and other corrosive substances through physical barriers, avoid aging and discoloration of the mirror coating, and significantly extend the service life of the wide-angle lens.

[0030] Working principle: First, when the lens body 2 needs to be disassembled, simply push the lens body 2 backward, causing the connecting frame 3 at the rear end to move backward, so that the arc surface of the locking block 5 contacts the slope surface of the locking groove 11, and the locking blocks 5 on both sides retract into the connecting frame 3. After retracting into the interior, the limiting blocks 7 on both sides slide downward by gravity, inserting the limiting blocks 7 into the limiting groove 6, thus limiting the locking blocks 5 and releasing the limiting of the lens body 2. Then, the spring 2 pushes the push plate 10, pushing the connecting frame 3 forward to remove the lens body 2, completing the disassembly. Second, when the lens body 2 is not in use, the baffle 12 is placed on the front side of the lens body 2, and the mounting frames 13 on both sides are inserted into the grooves on both sides and attracted to the metal by the magnet 14, thus protecting the lens body 2.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
