Technical Field
[0001] This utility model relates to the field of automotive sun visor technology, and in particular to a temperature-sensitive color-changing automotive sun visor. Background Technology
[0002] A car sun visor is a device installed on the top inside of a car's windshield. Its main function is to block sunlight or other strong light from shining directly into the eyes of the driver or passengers, thereby reducing glare and improving driving safety and passenger comfort.
[0003] Based on the above, the following problems were found: Current car sun visors are usually physical sunshades, which can effectively block direct sunlight, but they also obstruct the driver's vision. In the evening or early morning, when the angle of direct sunlight is small, the sun can easily shine directly into the driver's eyes. During this time, drivers need to frequently raise and lower the sun visor, which is quite inconvenient.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a temperature-sensitive color-changing car sun visor in order to achieve a more practical purpose. Utility Model Content

[0028] In one possible implementation, the threaded rod 29 passes through the middle of one side of the fixed block 21, and the threaded rod 29 is rotatably connected to the fixed block 21.
[0029] In this embodiment of the utility model, the threaded rod 29 is rotatably connected to the fixed block 21, which facilitates the fixing of the position of the threaded rod 29, so that the rotation of the threaded rod 29 can drive the sliding block 24 to slide.
[0030] In one possible implementation, a rotating block 210 is fixedly installed at the end of the threaded rod 29 away from the sliding block 24, and two operating rings 211 are hinged to the middle of the outer side of the rotating block 210.
[0031] In this embodiment of the utility model, the operation ring 211 is designed to facilitate outward flipping and control the rotation of the rotating block 210, thereby driving the threaded rod 29 to rotate.
[0032] In one possible implementation, an operation groove 212 is provided in the middle of one side of the fixed block 21, and the operation groove 212 is located on the outside of the rotating block 210.
[0033] In this embodiment of the utility model, the operation slot 212 provides storage space for the rotating block 210, making it convenient for the sunshade component 3 to be flipped upward and stored on one side of the original car sunshade 1. It can also be flipped synchronously with the original car sunshade 1 to block the light when the light intensity is high.
[0034] Specifically, the working principle of this temperature-sensitive color-changing car sun visor is as follows: During use, the fixing groove 22 allows it to be fitted onto the bottom of the original car sun visor 1, facilitating the fixed installation of the device. The operating groove 212 provides storage space for the rotating block 210, allowing the sun visor assembly 3 to be flipped upwards and stored on one side of the original car sun visor 1. Furthermore, when sunlight intensity is high, the sun visor assembly 3 and the original car sun visor 1 can be flipped synchronously to block sunlight.
