[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0030] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0031] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0032] An embodiment of the present application provides a rearview mirror, in which an airflow with a set flow rate provided by a heating power unit of the rearview mirror can be transported to an air outlet through an airflow channel inside the shell, and further output from the air outlet to a defog area, thereby increasing the flow rate of the airflow in the defog area; and the power unit can also input the airflow outside the shell from the air inlet into the shell, thereby reducing the defog power consumption of the rearview mirror while ensuring the defog efficiency of the lens.

[0033] Reference Figure 1 , an embodiment of the present application provides a rearview mirror, the rearview mirror comprising:

[0034] A housing 1, wherein the front side of the housing 1 has a viewing window 11;

[0035] The lens 2 is disposed in the housing 1 and has an air outlet 12 and an air inlet 13 between the housing 1, and a defogging area is formed between the lens 2 and the window 11;

[0036] The power unit 3 is disposed in the housing 1 . The power unit 3 can output airflow to the demisting area through the air outlet 12 and obtain airflow input from the air inlet 13 .

[0037] In this embodiment, when the rearview mirror is in use, the side that facilitates the user's field of vision is the front side. For example, when the rearview mirror is located on the vehicle, the side of the rearview mirror facing the driver is the front side of the rearview mirror, and the other surfaces of the rearview mirror except the front side are the back side of the rearview mirror. For example, the back side of the rearview mirror may include the side of the rearview mirror away from the driver, and the side surface of the rearview mirror located between the side facing the driver and the side away from the driver.

[0038] The front of the shell 1 is on the same side as the front of the rearview mirror, and the back of the shell 1 is on the same side as the back of the rearview mirror. The front of the shell 1 has a window 11, for example, a channel communicating with the outside is formed on the front of the shell 1, and the lens 2 is arranged in the shell 1, and the mirror side of the lens 2 faces the channel of the window 11, so that the user can observe the field of view image captured on the lens 2 through the window 11.

[0039] In this embodiment, the power unit 3 can be an air source or an air pump. The airflow with a set flow rate provided by the power unit 3 can be transported to the air outlet 12 through the air flow channel inside the shell 1, and further output from the air outlet 12 to the demisting area, thereby increasing the flow rate of the airflow in the demisting area; and the power unit 3 can also input the airflow outside the shell 1 from the air inlet 13 into the shell 1, thereby improving the demisting efficiency on the mirror side of the lens 2.

[0040] Specifically, the air outlet 12 and the air inlet 13 between the lens 2 and the housing 1 can be connected to the power unit 3. When the power unit 3 is in operation, it can drive the airflow of the housing 1 to be output from the housing 1 through the air outlet 12, and the power unit 3 can input the airflow outside the housing 1 into the housing 1 through the air inlet 13. The airflow direction is shown in FIG. Figures 1 to 3 As indicated by the arrow.

[0041] See also Figure 1 A demisting area is formed between the lens 2 and the window 11, and the opening of the air outlet 12 faces the demisting area. The airflow output from the shell 1 from the air outlet 12 can enter the demisting area. The demisting area is close to the mirror side of the lens 2, so the mirror side of the lens 2 can be demisted by the airflow flowing in the demisting area, thereby improving the demisting efficiency of the lens 2.

[0042] At the same time, the air inlet 13 can also be opposite to the defog area, so that the airflow in the defog area can be input into the shell 1 through the air inlet 13. For example, at least part of the airflow output from the air outlet 12 can be input into the shell 1 from the air inlet 13, or at least part of the airflow output from the air outlet 12 and the airflow outside the shell 1 (excluding the airflow output from the air outlet 12) can be input into the shell 1 from the air inlet 13 together to form a circulating airflow flow. On the basis of ensuring the defog efficiency of the lens 2, the defog power consumption of the rearview mirror can also be reduced.

[0043] In this embodiment, the window 11 is located on the front side of the shell 1, and the lens 2 can be arranged towards the inside of the shell 1 relative to the window 11, that is, a demisting area located inside the shell 1 and directly exposed to the outside can be formed between the lens 2 and the window 11, and the demisting area is in direct contact with the mirror side of the lens 2, so that the airflow in the demisting area can defog the mirror side of the lens 2.

[0044] Furthermore, when the rearview mirror is located on the vehicle and the vehicle is moving forward in the rain, the power unit 3 is activated and drives the airflow of the shell 1 to be output from the air outlet 12 to the shell 1, and the airflow flows from the edge of the lens 2 to the defogging area through the air outlet 12. The airflow in the defogging area can accelerate the air flow on the mirror side of the lens 2, thereby achieving a rapid defogging effect; and the faster the vehicle speed, the higher the power of the power unit 3 can be, thereby increasing the airflow output from the air outlet 12 to the defogging area, thereby enhancing the defogging effect on the mirror side of the lens 2.

[0045] At the same time, at least part of the airflow output from the air outlet 12 can be input into the shell 1 from the air inlet 13. For example, the power unit 3 can suck the airflow in the demisting area into the shell 1 through the air inlet 13. The airflow in the demisting area includes at least part of the airflow output from the air outlet 12 and the airflow outside the shell 1 to form a circulating airflow flow, thereby improving the demisting efficiency of the rearview mirror.

[0046] In addition, when the airflow on the mirror surface side of the lens 2 continues to flow, the flowing airflow can also prevent raindrops from approaching the lens 2, thereby reducing the risk of fogging on the lens 2. Moreover, the rearview mirror provided in the embodiment of the present application avoids setting an air inlet hole on the back of the housing 1, thereby reducing the air resistance of the rearview mirror.

[0047] The rearview mirror provided in the embodiment of the present application includes a shell 1, the front side of the shell 1 has a window 11; a lens 2, the lens 2 is arranged in the shell 1 and has an air outlet 12 and an air inlet 13 between the shell 1, and a defogging area is formed between the lens 2 and the window 11; a power unit 3, the power unit 3 is arranged in the shell 1, the power unit 3 can output airflow to the defogging area through the air outlet 12, and obtain the airflow input from the air inlet 13, on the basis of ensuring the defogging efficiency of the lens 2, it can also reduce the defogging power consumption of the rearview mirror.

[0048] In one embodiment, see Figure 1 The air outlet 12 and the air inlet 13 are located on opposite sides of the lens 2 .

[0049] In this embodiment, when the power unit 3 is in operation, it can output airflow to the demisting area through the air outlet 12, and obtain the airflow in the demisting area through the air inlet 13 and then input it into the interior of the shell 1; in order to facilitate the airflow output from the air outlet 12 to smoothly enter the interior of the shell 1 through the air inlet 13, the air outlet 12 and the air inlet 13 can be relatively arranged on both sides of the lens 2, so that the outlet direction of the air outlet 12 is toward the inlet direction of the air inlet 13, thereby improving the efficiency of the airflow circulation between the air outlet 12 and the air inlet 13.

[0050] In a specific embodiment, the air outlet 12 and the air inlet 13 are located on the upper and lower sides of the lens 2, and the air outlet 12 and the air inlet 13 are opposite to each other up and down, and the air outlet 12 outputs the air flow downward toward the air inlet 13, so that the air flow output by the air outlet 12 can enter the interior of the shell 1 through the air inlet 13 as much as possible; in another specific embodiment, the opening size of the air inlet 13 is larger than the opening size of the air outlet 12, which can also make the air flow output by the air outlet 12 enter the interior of the shell 1 through the air inlet 13 more.

[0051] In one embodiment, there are multiple air outlets 12 and multiple air inlets 13 between the lens 2 and the shell 1, the multiple air outlets 12 are arranged at intervals on the first side of the lens 2, and the multiple air inlets 13 are arranged at intervals on the second side of the lens 2, and the second side and the first side are located on opposite sides of the lens 2.

[0052] In this embodiment, the lens 2 has a width dimension and a height dimension. The dimension of the lens 2 in the left-right direction can be the width dimension, and the dimension of the lens 2 in the up-down direction can be the height dimension. Multiple air outlets 12 are arranged at intervals on the first side of the lens 2 and can cover the lens 2 in the width direction of the lens 2 to ensure that the airflow output from the air outlet 12 to the defog area can comprehensively defog the mirror side of the lens 2.

[0053] The multiple air inlets 13 are arranged at intervals on the second side of the lens 2, and the multiple air inlets 13 can also cover the lens 2 in the width direction of the lens 2, so as to ensure the effective circulation of the air flow output from the air outlet 12, and also increase the air intake of the air inlet 13, so that the power unit 3 has a sufficient air source.

[0054] In one embodiment, see Figure 1 and Figure 2 The rearview mirror further includes a first heating unit 4, an air outlet channel is formed between the power unit 3 and the air outlet 12, and the first heating unit 4 is arranged in the air outlet channel.

[0055] In this embodiment, the first heating unit 4 may include a heating wire or a heating film. When the airflow is transported between the power unit 3 and the air outlet 12, the first heating unit 4 can heat the airflow so that the airflow output from the air outlet 12 to the defogging area is a hot airflow. The hot airflow can accelerate the evaporation of water vapor on the lens 2 and improve the defogging efficiency of the lens 2.

[0056] In one embodiment, one or more air outlet channels can be formed between the power unit 3 and the air outlet 12. For example, when there are multiple air outlets 12 between the lens 2 and the shell 1, a channel can be formed between the power unit 3 and the multiple air outlets 12; or, a channel can be formed between the power unit 3 and each air outlet 12, that is, multiple channels are set to correspond to the multiple air outlets 12; and the multiple channels can be some of the channels corresponding to the first heating unit 4, or all the channels can be corresponding to the first heating unit 4, so as to flexibly adjust the defog efficiency of the lens 2.

[0057] In one embodiment, see Figure 1 An air intake channel is formed between the power unit 3 and the air intake port 13 , and a circulation channel is formed through the power unit 3 through the air outlet channel, the demisting area and the air intake channel.

[0058] In this embodiment, the airflow output from the air outlet 12 by the power unit 3 through the air outlet channel can all enter the air inlet channel through the air inlet 13 after defogging the lens 2 in the defog area, so as to form a closed circulation channel of the air outlet channel, the defog area and the air inlet channel through the power unit 3, which can not only ensure the defog efficiency of the lens 2, but also reuse the defog airflow, thereby reducing the power consumption of defogging the rearview mirror.

[0059] Alternatively, after the airflow output from the air outlet 12 by the power unit 3 through the air outlet channel defogs the lens 2 in the defog area, part of the airflow enters the air inlet channel through the air inlet 13, and at the same time, the airflow entering the air inlet channel through the air inlet 13 can also include external airflow to ensure the air flow entering the air inlet channel through the air inlet 13.

[0060] In one embodiment, see Figure 1 The power unit 3 includes a pump body, an air inlet end of the pump body is connected to an air inlet passage, and an air outlet end of the pump body is connected to an air outlet passage.

[0061] In this embodiment, the airflow entering the air inlet channel through the air inlet 13 can enter the interior of the pump body from the air inlet end of the pump body, and be output from the air outlet end of the pump body after being compressed inside the pump body, so as to increase the flow rate and flow of the airflow in the air outlet channel, and ensure the efficiency of the airflow output from the air outlet 12 in defogging the lens 2 in the defog area.

[0062] In one embodiment, see Figure 2and Figure 3 The first heating unit 4 includes a heating part 41 and a temperature control part 42 . The heating part 41 is arranged in the air outlet channel. The temperature control part 42 is electrically connected to the heating part 41 and is used to control the heating temperature of the heating part 41 .

[0063] In this embodiment, the heating part 41 can be a heating wire or a heating film, and the temperature control part 42 can include a temperature control controller and a temperature control sensor. The temperature control sensor is a temperature sensor or a thermistor. The temperature control sensor is arranged close to the heating part 41 and can monitor the heating temperature of the heating part 41. At the same time, the temperature control controller can adjust the temperature of the heating part 41 according to the heating temperature of the heating part 41 to avoid damage to the heating part 41 due to excessive temperature, thereby playing a high temperature protection function.

[0064] In one embodiment, see Figure 1 The rearview mirror further includes a second heating unit 5 , which is disposed on a side of the lens 2 away from the window 11 .

[0065] In this embodiment, the side of the lens 2 close to the window 11 is the mirror side of the lens 2, and the side of the lens 2 away from the window 11 is the back side of the lens 2. The second heating unit 5 can be an electric heating wire, an electric heating sheet or an electric heating film. The second heating unit 5 is close to or attached to the back side of the lens 2. It can increase the defog rate of the lens 2 by increasing the temperature of the lens 2 without affecting the external field of view displayed by the lens 2.

[0066] In one embodiment, see Figure 3 , the rearview mirror also includes a rain sensor 6, which is arranged on the housing 1 and is used to monitor rainfall information;

[0067] When the rainfall information reaches a set threshold, at least one of the power unit 3, the first heating unit 4 and the second heating unit 5 is in an operating state.

[0068] In this embodiment, the rearview mirror also includes a rain sensor 6 and a controller. The rain sensor 6 is arranged on the shell 1 and is used to monitor the rainfall in the environment where the rearview mirror is located. The rain sensor 6 can transmit rainfall information to the controller, and the power unit 3, the first heating unit 4 and the second heating unit 5 are electrically connected to the controller.

[0069] When the rainfall information monitored by the rain sensor 6 reaches the set threshold, that is, when the rainfall will affect the display of the image lens 2, the controller controls one or more of the power unit 3, the first heating unit 4 and the second heating unit 5 to act simultaneously, such as controlling the power unit 3 to increase the airflow rate entering the defogging area, or controlling the first heating unit 4 to increase the airflow temperature entering the defogging area, or controlling the second heating unit 5 to directly heat the lens 2, all of which can increase the defogging effect of the rearview mirror.

[0070] An embodiment of the present application provides a vehicle, which includes the above-mentioned rearview mirror.

[0071] In this embodiment, the rearview mirror of the vehicle includes a shell 1, the front of the shell 1 has a window 11; a lens 2, the lens 2 is arranged in the shell 1 and has an air outlet 12 and an air inlet 13 between the shell 1, and a defog area is formed between the lens 2 and the window 11; a power unit 3, the power unit 3 is arranged in the shell 1, the power unit 3 can output airflow to the defog area through the air outlet 12, and obtain the airflow input from the air inlet 13, on the basis of ensuring the defog efficiency of the lens 2, it can also reduce the defog power consumption of the rearview mirror.
