Detailed implementation manners

[0023] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0024] Referring to the attached Figures 1 to 5 specification, a rearview mirror with an intelligent electronic display mechanism includes: a rearview mirror housing 1, and a display screen 11 is installed on the rearview mirror housing 1;

[0025] A rain shield assembly 2 is provided on the rearview mirror housing 1. The rain shield assembly 2 includes a rain shield 21, and the rain shield 21 is fixedly arranged on the rearview mirror housing 1. The rain shield assembly 2 blocks part of the rain from falling on the display screen 11 through the rain shield 21;

[0026] An air blowing assembly 3 is arranged inside the rearview mirror housing 1. The air blowing assembly 3 includes a fan one 31 and a heating assembly 34. An air inlet one 32 is opened on the rearview mirror housing 1. The fan one 31 sucks air into the rearview mirror housing 1 through the air inlet one 32. The heating assembly 34 is used to heat the air. An air outlet one 351 and an air outlet two 361 are further provided on the rain shield 21. The air outlet end of the air outlet one 351 points to the display screen 11, and the air outlet end of the air outlet two 361 is parallel to the display screen 11.

[0027] It should be noted that the heating assembly 34 can be an electric heating wire, and the air is heated by energizing the electric heating wire.

[0028] The implementation scenario is as follows: When the vehicle is moving, part of the rainwater is blocked by the rain shield 21 to reduce the rainwater falling on the display screen 11. At the same time, the first blower 31 is driven to draw air into the rearview mirror housing 1 through the first air inlet 32, and the air is heated by the electric heating wire. Then, the first blower 31 blows the heated hot air out through the first air outlet 351 and the second air outlet 361, so that the hot air blown out from the first air outlet 351 blows towards the display screen 11 to defog the display screen 11. At the same time, the hot air blown out from the second air outlet 361 can form an air curtain in front of the display screen 11, and the rainwater blown towards the display screen 11 is blocked by the air curtain, so that the rainwater blown towards the display screen 11 can be reduced, and the hot air can defog the display screen 11 and reduce the influence of rainwater on defogging.

[0029] Further, referring to the attached drawings of the specification Figure 1 The top of the rain shield 21 is inclined, and a plurality of water guide grooves 211 are provided at the top of the rain shield 21.

[0030] It should be noted that when part of the rainwater falls on the rain shield 21, the rainwater can fall through the plurality of inclined water guide grooves 211, so that the rainwater falling on the display screen 11 can be reduced. At the same time, when the rainwater flowing down from the water guide grooves 211 flows down, it can flow towards the rainwater falling on the air curtain, so that the rainwater flowing down from the water guide grooves 211 can take away part of the rainwater about to fall on the air curtain, which can reduce the pressure of blocking rainwater and further reduce the influence of rainwater on defogging.

[0031] Further, referring to the attached drawings of the specification Figures 2 to 5 The blowing assembly 3 further includes a pipeline 33. The air outlet end of the first blower 31 is communicated with the pipeline 33. The pipeline 33 is installed in the rearview mirror housing 1. The heating assembly 34 is installed in the pipeline 33. The heating assembly 34 is used to heat the air entering the pipeline 33. An air duct 35 and an air duct 36 are provided in the rain shield 21. The air duct 35 is communicated with the air duct 36, and the air outlet end of the pipeline 33 is communicated with the air duct 36. The air duct 35 is communicated with the first air outlet 351, and the air duct 36 is communicated with the second air outlet 361.

[0032] It should be noted that the first blower 31 draws external air into the pipeline 33 through the first air inlet 32. When the air flows in the pipeline 33, the air is heated by the heating assembly 34, and the heated hot air is transported into the air ducts 35 and 36, and the hot air is blown out from the first air outlet 351 and the second air outlet 361, so that the hot air blown out from the first air outlet 351 blows towards the display screen 11 and defogs the display screen 11, and the hot air blown out from the second air outlet 361 forms an air curtain in front of the display screen 11 to block rainwater.

[0033] In the above technical solution, an air curtain parallel to the display screen 11 is blown out through the second air outlet 361 to block rainwater. However, since heavy rainfall is usually accompanied by strong winds, although during the driving of the vehicle, the rainwater and strong winds are moving backward relative to the rearview mirror housing 1 itself, due to the slow speed of departure usually during heavy rainfall and strong winds, the strong wind will blow towards the display screen 11. When the strong wind blows towards the display screen 11, it will first blow towards the air curtain, resulting in the strong wind disturbing the air curtain and causing the problem that the air curtain cannot block rainwater. Furthermore, there will be a problem that the strong wind and rainwater will blow towards the display screen 11 together, making it difficult to quickly evaporate a large amount of water droplets falling on the mirror surface. Therefore, the present utility model proposes a turbulent flow component 4, which blows the strong wind through the airflow to disturb the strong wind blowing towards the display screen 11 and weaken the strong wind to prevent the strong wind from blowing directly towards the air curtain.

[0034] Specifically, referring to the attached drawings of the specification Figure 6 and Figure 7 a turbulent flow component 4 is provided on the rearview mirror housing 1. The turbulent flow component 4 includes a second blower 42, and the turbulent flow component 4 blows air towards the external wind force through the second blower 42.

[0035] The turbulent flow component 4 includes a side box 41. The side box 41 is fixedly arranged on the rearview mirror housing 1. The second blower 42 is installed in the side box 41. An air inlet 43, an air outlet 44 and a drain hole 45 are provided on the side box 41. The air inlet 43, the second blower 42 and the air outlet 44 are aligned in the horizontal direction.

[0036] It should be noted that by driving the second blower 42, it intakes air through the air inlet 43 and blows out air through the air outlet 44, so that the air flow collides with the external strong wind, disturbing the external strong wind and weakening the wind force, preventing the strong wind from blowing directly towards the air curtain. By disturbing the strong wind and weakening the wind force, the wind force when blowing towards the air curtain is smaller, thus solving the problem that the strong wind blows directly towards the air curtain and drives the rainwater to blow towards the display screen 11 together.

[0037] Furthermore, referring to the attached drawings of the specification Figure 1 and Figure 2 an intelligent display mechanism 5 is provided on the rearview mirror housing 1. The intelligent display mechanism 5 includes a camera 51. The camera 51 is installed at the bottom of the rearview mirror housing 1. A controller 52 is arranged in the rearview mirror housing 1. The output end of the camera 51 is connected to the input end of the controller 52, and the output end of the controller 52 is connected to the display screen 11.

[0038] It should be noted that the controller 52 can be a PLC or a single-chip microcomputer. By capturing the pictures during driving through the camera 51 and displaying the captured pictures through the controller 52 on the display screen 11, the driver can reduce accidents caused by observation blind spots during driving and can provide a clearer and wider rear view.

[0039] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
