Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.
[0024] The following describes in detail, with reference to the accompanying drawings, a self-heating device for a car rearview mirror according to an embodiment of the present invention.
[0025] Example 1
[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of a self-heating device for a car rearview mirror provided by this utility model includes a rear seat 1, a lens body 2 is provided on one side of the rear seat 1, a mirror surface 201 and a light-transmitting surface 202 are provided on one side of the lens body 2, and a detachable fixing component and an automatic heating component are provided between the rear seat 1 and the lens body 2.
[0027] The detachable fixing assembly includes a mounting bracket 301, a slot 302, a locking block 303, a bolt seat 304, a fixing ear 305, and a fixing bolt 306. The mounting bracket 301 is fixedly connected to one side of the lens body 2. The slot 302 is formed at one end of the mounting bracket 301. The bolt seat 304 is fixedly connected to one side wall of the rear seat 1. The fixing ear 305 is fixedly connected to one side wall of the mounting bracket 301. The fixing bolt 306 is fixedly installed between the bolt seat 304 and the fixing ear 305. One end of the locking block 303 is sleeved inside the slot 302, and the shape of the locking block 303 matches that of the slot 302. The fixing bolt 306 is rotatably connected to the inside of the fixing ear 305. The fixing bolt 306 and the bolt seat 304 are connected by threads.
[0028] It should be noted that by setting a locking block 303 and a bolt seat 304 on the separate rear seat 1, and using glue to attach the mounting bracket 301 to the lens body 2, and by opening a slot 302 and a fixing ear 305 on the mounting bracket 301, the locking block 303 is inserted into the slot 302, and the fixing bolt 306 is threaded through the fixing ear 305 and into the bolt seat 304 to connect the lens body 2 and the rear seat 1 with the automatic heating component. When the lens body 2 is damaged, the rearview mirror is removed as a whole, and then the fixing bolt 306 is rotated to disengage it from the bolt seat 304. At this time, the locking block 303 can be pulled out from the slot 302, and the broken lens body 2 can be removed and replaced with a new lens with a mounting bracket 301. There is no need to replace the lens assembly with the heating wire, thereby reducing maintenance costs.
[0029] Example 2
[0030] In some embodiments, such as Figure 2 , Figure 3 As shown, the automatic heating assembly includes an electric heating wire 401, a thermally conductive silicone plate 402, a transfer controller 403, a mounting slot 404, and an optical sensor 405. The electric heating wire 401 is fixedly installed on one side of the rear seat 1, the thermally conductive silicone plate 402 is fixedly installed on one side of the electric heating wire 401, the transfer controller 403 is fixedly installed on the rear side of the rear seat 1, the mounting slot 404 is opened at one end of the rear seat 1, and the optical sensor 405 is fixedly installed inside the mounting slot 404. The electric heating wire 401 and the optical sensor 405 are both electrically connected to the transfer controller 403 by wires. One side surface of the thermally conductive silicone plate 402 abuts against one side surface of the lens body 2. The mounting slot 404 is located on one side of the light-transmitting surface 202, and the output end of the optical sensor 405 is located on one side of the light-transmitting surface 202.
[0031] It should be noted that by setting up an optical sensor 405, the sensor detects the lens surface through the light-transmitting surface 202 and transmits the data to the relay controller 403. When there is frost, ice, or water droplets on the lens body 2, the relay controller 403 automatically supplies power to the electric heating wire 401, and heats the lens body 2 through the thermally conductive silicone plate 402. No manual activation is required, making it convenient to use. The relay controller 403 has a microprocessor module for processing the information received by the optical sensor 405 and a power supply module for powering the electric heating wire 401. The optical sensor 405 works by emitting light (usually infrared or laser) and detecting the intensity of the reflected light. When there is no rain or other fog or frost obstructing the light, the reflected light is strong; when rain falls on the sensor surface, the intensity of the reflected light weakens. This change in intensity can be detected and analyzed to determine whether there is rain or other fog or frost.
[0032] Working principle: First, the fixed bolt 306 is threaded through the fixed ear 305 and into the bolt seat 304 to connect the lens body 2 and the rear seat 1 with the automatic heating component. When the lens body 2 is damaged, the rearview mirror is removed as a whole, and then the fixed bolt 306 is rotated to disengage it from the bolt seat 304. At this time, the clip 303 can be pulled out from the slot 302, and the broken lens body 2 can be removed and replaced with a new lens with a mounting bracket 301. There is no need to replace the lens assembly with the heating wire. During operation, the optical sensor 405 detects the lens surface through the light-transmitting surface 202 and transmits the data to the transfer controller 403. When there is frost, ice or water droplets on the lens body 2, the transfer controller 403 will automatically supply power to the electric heating wire 401 and heat the lens body 2 through the heat-conducting silicone plate 402. No manual start is required, making it convenient to use.
