[0041] 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.

[0042] Reference Figures 1 to 4 , an embodiment of the present application provides a rearview mirror, the rearview mirror comprising:

[0043] A housing 1, wherein the front side of the housing 1 has a viewing window 11;

[0044] The lens 2 is disposed in the housing 1 and has an air flow opening 13 between the lens 2 and the housing 1, and a defogging area is formed between the lens 2 and the window 11;

[0045] A power unit 3, which is disposed in the housing 1 and includes a steering structure 31 and an air pump 32, wherein the steering structure 31 is connected to the air pump 32;

[0046] A plurality of airflow channels are formed between the power unit 3 and the airflow port 13, and the airflow channels are connected to the demisting area. The steering structure 31 can drive the air pump 32 to turn so that the outlet of the air pump 32 faces part of the airflow channels.

[0047] 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.

[0048] 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.

[0049] See also Figure 1 A demisting area is formed between the lens 2 and the window 11, and the opening of the air flow port 13 faces the demisting area. The airflow output from the air flow port 13 to the shell 1 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 air flow flowing in the demisting area, thereby improving the demisting efficiency of the lens 2; in addition, the airflow in the demisting area can also be sucked into the interior of the shell 1 through the air inlet formed by the air flow port 13 to form a circulating airflow path.

[0050] 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.

[0051] 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 fundamentally reducing the risk of fogging on the lens 2.

[0052] In one embodiment, there may be one or more air flow openings 13 between the lens 2 and the shell 1, such as an annular air flow opening 13 between the lens 2 and the shell 1, or there may be multiple air flow openings 13 between the lens 2 and the shell 1. The multiple air flow openings 13 may be evenly spaced around the lens 2 to increase the air outlet of the air flow openings 13 and ensure the demisting effect of the air flow in the demisting area on the lens 2.

[0053] In a specific embodiment, there are two air flow openings 13 between the lens 2 and the shell 1. The two air flow openings 13 form two air outlets. The two air outlets are respectively arranged on the upper and lower sides of the lens 2. The air flow can enter the interior of the shell 1 through the air inlet window 12 on the back of the shell 1, and then flow from the upper and lower sides of the lens 2 to the demisting area through the air outlet, thereby achieving a quick demisting effect.

[0054] The multiple air flow channels may include an air outlet channel and an air inlet channel, the air outlet channel corresponds to the air outlet formed by the connected air flow outlet 13, and the air inlet channel corresponds to the air inlet formed by the connected air flow outlet 13; the steering structure 31 can drive the air pump 32 to steering, so that the outlet of the air pump 32 is oriented toward one or more air outlet channels in the first state, and the outlet of the air pump 32 is oriented toward another or more air outlet channels in the second state, while ensuring the defog effect of the lens 2, the flexibility of the air flow in the rearview mirror is improved.

[0055] In one embodiment, see Figure 4 and Figure 6 , the air flow channel includes an upper channel and a lower channel, the upper channel and the lower channel are respectively located at the upper and lower sides of the lens 2, and the air flow port 13 includes an air outlet;

[0056] The steering structure 31 can drive the outlet of the air pump 32 toward the upper channel, so that the upper channel is connected to the defogging area through the air outlet. The airflow passes through the air outlet at the top of the lens 2 and then blows downward toward the defogging area, so that at least part of the airflow in the defogging area flows from top to bottom. The airflow can drive the water droplets and water mist on the lens 2 to flow downward, making it easier to remove the water droplets and water mist from the lens 2, thereby improving the defogging effect of the lens 2.

[0057] In one embodiment, see Figure 5 and Figure 7 The air flow channel includes an upper channel and a lower channel, the upper channel and the lower channel are respectively located at the upper and lower sides of the lens 2, the steering structure 31 can drive the outlet of the air pump 32 toward the lower channel, and the air flow port 13 includes an air outlet;

[0058] The lower channel is connected to the defog area through the air outlet, and the air flow passes through the air outlet at the bottom of the lens 2 and blows toward the defog area, so that at least part of the accumulated water and solid impurities in the lower channel are discharged from the air flow outlet 13 at the bottom, ensuring the cleanliness of the interior of the rearview mirror.

[0059] In one embodiment, see Figures 4 to 7 The rearview mirror further includes a switch unit 7. The back of the housing 1 has an air intake window 12. The switch unit 7 is disposed at the air intake window 12 and is used to control the opening and closing of the air intake window 12.

[0060] When the switch unit 7 controls the air intake window 12 to be in an open state, the air intake window 12 is connected to the back side of the housing and the demisting area through the air flow opening 13 .

[0061] In this embodiment, the air intake window 12 on the back of the shell 1 can be an opening on the back of the shell 1 or a hole area connected to the inside of the shell 1, so that the airflow outside the rearview mirror can enter the interior of the shell 1 through the air intake window 12; and there is an air flow port 13 between the lens 2 and the shell 1, and the switch unit 7 can control the opening and closing of the air intake window 12.

[0062] When the rearview mirror does not need to be defogged, for example, when the environment in which the rearview mirror is located is free of rain or fog, the air intake window 12 can be closed by controlling the switch unit 7 to avoid the formation of an air intake hole on the rearview mirror to increase air resistance.

[0063] When the rearview mirror needs to be defogged, for example, when the environment in which the rearview mirror is located is a rainy and foggy environment, the air intake window 12 can be controlled to open by the switch unit 7, and the rearview mirror can be aired into the interior of the housing 1 through the air intake window 12, and the air intake window 12 is connected to the air flow port 13 through the air flow channel inside the housing 1, so that the external airflow can be transmitted through the air intake window 12 in the housing 1, and the airflow can also be output from the housing 1 from the air flow port 13. Figures 1 to 3 As indicated by the arrow.

[0064] Furthermore, when the rearview mirror is located on the vehicle and the vehicle is moving forward in the rain, the switch unit 7 controls the air intake window 12 to open, and the airflow flowing in the opposite direction to the vehicle can enter the interior of the shell 1 through the air intake window 12 on the back side of the shell 1, and the airflow then flows from the edge of the lens 2 to the defogging area through the air flow port 13. The airflow in the defogging area can accelerate the air flow on the mirror side of the lens 2, thereby achieving a quick defogging effect; and the faster the vehicle speed, the higher the airflow velocity entering the interior of the shell 1 through the air intake window 12 on the back side of the shell 1, thereby increasing the airflow output from the air flow port 13 to the defogging area, thereby improving the defogging effect on the mirror side of the lens 2.

[0065] In another embodiment, the opening degree of the air intake window 12 controlled by the switch unit 7 can be proportional to the speed of the vehicle. The faster the speed of the vehicle, the larger the opening degree of the air intake window 12 controlled by the switch unit 7, and the higher the air flow velocity entering the interior of the shell 1 through the air intake window 12 on the back side of the shell 1, thereby increasing the air flow output from the air flow port 13 to the demisting area.

[0066] In this embodiment, by arranging the power unit 3 inside the shell 1, when the switch unit 7 controls the air intake window 12 to be closed, the power unit 3 can still provide a flowing airflow, so that the airflow is output to the defog area through the air flow port 13, thereby ensuring the defog effect on the lens 2 while avoiding the formation of an air intake hole on the rearview mirror to increase the air resistance.

[0067] When the switch unit 7 controls the air intake window 12 to be in an open state, the power unit 3 can actively inhale air from the air intake window 12, and after the power unit 3 compresses the airflow, the compressed airflow is output to the defog area through the airflow port 13, thereby increasing the flow velocity and flow rate of the airflow and improving the defog rate on the mirror side of the lens 2.

[0068] In this embodiment, the power unit 3 can be an air source or an air pump. The power unit 3 is arranged in the air outlet channel between the switch unit 7 and the air outlet 13. The airflow with a set flow rate provided by the power unit 3 can be transported to the air outlet 13 through the air flow channel inside the shell 1, and further output from the air outlet 13 to the demisting area, thereby increasing the flow rate of the airflow in the demisting area; and the airflow provided by the power unit 3 can be mixed with the airflow entering the shell 1 through the air inlet window 12, thereby improving the demisting efficiency on the mirror side of the lens 2.

[0069] In a specific embodiment, see Figure 4 The air flow channel includes an upper channel and a lower channel respectively located on the upper and lower sides of the lens 2. When the switch unit 7 controls the air intake window 12 to be in an open state, the steering structure 31 drives the outlet of the air pump 32 toward the upper channel.

[0070] Specifically, the air intake window 12 is controlled to open by the switch unit 7, and the air pump 32 can be driven to turn by the steering structure 31. The steering structure 31 drives the outlet of the air pump 32 toward the upper channel, so that the airflow on the lens 2 flows from top to bottom after being output from the airflow outlet 13, thereby driving the water mist on the lens 2 downward, thereby improving the demisting efficiency on the lens 2.

[0071] In a specific embodiment, see Figure 5 The air flow channel includes an upper channel and a lower channel respectively located on the upper and lower sides of the lens 2. When the switch unit 7 controls the air intake window 12 to be in an open state, the steering structure 31 drives the outlet of the air pump 32 toward the lower channel.

[0072] Specifically, by controlling the air intake window 12 to open through the switch unit 7, the rearview mirror can take in air into the interior of the shell 1 through the air intake window 12, and at this time, rainwater outside the rearview mirror can also easily take in air into the interior of the shell 1 through the air intake window 12; in order to facilitate the drainage inside the rearview mirror, the air pump 32 can be driven to turn through the steering structure 31 so that the outlet of the air pump 32 faces the lower channel, which facilitates the drainage of rainwater inside the rearview mirror through the lower channel, thereby avoiding water accumulation inside the rearview mirror and damaging the internal components.

[0073] In one embodiment, see Figure 6 and Figure 7 When the switch unit 7 controls the air intake window 12 to be in a closed state, the air pump 32, the upper channel, the lower channel and the demisting area form a circulating airflow path.

[0074] In this embodiment, one of the upper channel and the lower channel is an air outlet channel, and the other is an air inlet channel; the air pump 32 has an outlet and an inlet, the air pump 32 outputs airflow to the air outlet channel through the outlet, the air outlet channel conveys airflow to the defogging area through the air outlet formed by the air flow port 13, the airflow in the defogging area can also enter the air inlet channel through the air inlet formed by the air flow port 13, the airflow in the air inlet channel flows back to the inlet of the air pump 32, so as to form a circulating airflow path through the air pump 32, thereby improving the efficiency of airflow delivery and reducing power consumption during defogger of the rearview mirror.

[0075] In one embodiment, see Figure 6 The air flow outlet 13 includes an air outlet and an air inlet, the upper channel is connected to the demisting area through the air outlet, and the lower channel is connected to the demisting area through the air inlet;

[0076] The steering structure 31 can drive the outlet of the air pump 32 toward the upper channel, and the inlet of the air pump 32 toward the lower channel.

[0077] In a specific embodiment, see Figure 6 The air flow channel includes an upper channel and a lower channel respectively located on the upper and lower sides of the lens 2. When the switch unit 7 controls the air intake window 12 to be in a closed state, the steering structure 31 drives the outlet of the air pump 32 toward the upper channel, and the inlet of the air pump 32 toward the lower channel.

[0078] In this embodiment, when the switch unit 7 controls the air intake window 12 to be closed, the rearview mirror may not need to be defogged, or the rearview mirror may be defogged through the action of the power unit 3 .

[0079] Specifically, the steering structure 31 drives the outlet of the air pump 32 toward the upper channel, and the compressed airflow output by the air pump 32 can be output from the air flow port 13 through the upper channel and enter the defogging area. The mirror side of the lens 2 is defogged by the airflow flowing in the defogging area, thereby improving the defogging efficiency of the lens 2. At the same time, the inlet of the air pump 32 is toward the lower channel, and the airflow in the defogging area can enter the lower channel through the air inlet and be sucked into the air pump from the inlet of the air pump 32 to form a circulating airflow path. The air inlet and the air outlet can be opposite to each other up and down. By recycling the airflow, the power consumption of the rearview mirror defogging can be reduced while ensuring the defogging effect.

[0080] In a specific embodiment, see Figure 7 The air flow channel includes an upper channel and a lower channel respectively located on the upper and lower sides of the lens 2. When the switch unit 7 controls the air intake window 12 to be in a closed state, the steering structure 31 drives the outlet of the air pump 32 toward the lower channel, and the inlet of the air pump 32 toward the upper channel.

[0081] In this embodiment, when the switch unit 7 controls the air intake window 12 to be closed, the rearview mirror may not need to be defogged, or the rearview mirror may be defogged through the action of the power unit 3 .

[0082] Specifically, the steering structure 31 drives the outlet of the air pump 32 toward the lower channel, and the compressed airflow output by the air pump 32 can be output from the air flow port 13 through the lower channel and enter the defogging area. The mirror side of the lens 2 is defogged by the airflow flowing in the defogging area, thereby improving the defogging efficiency of the lens 2. At the same time, the inlet of the air pump 32 is toward the upper channel, and the airflow in the defogging area can enter the upper channel through the air inlet and be sucked into the air pump from the inlet of the air pump 32 to form a circulating airflow path. The air inlet and the air outlet can be opposite to each other up and down. By recycling the airflow, the power consumption of the rearview mirror defogging can be reduced while ensuring the defogging effect.

[0083] In one embodiment, see Figure 1 and Figure 3 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 13. The first heating unit 4 is disposed in the air outlet channel.

[0084] In this embodiment, the first heating unit 4 can be a heating wire or a heating film. When the air flow is transported between the air inlet window 12 and the air outlet 13, the first heating unit 4 can heat the air flow so that the air flow output from the air outlet 13 to the defogging area is a hot air flow. The hot air flow can accelerate the evaporation of water vapor on the lens 2 and improve the defogging efficiency of the lens 2.

[0085] In one embodiment, one or more air outlet channels can be formed between the power unit 3 and the air outlet 13. For example, when there are multiple air outlets 13 between the lens 2 and the shell 1, an annular channel can be formed between the power unit 3 and the multiple air outlets 13; or, an air outlet channel can be formed between the power unit 3 and each air outlet 13, that is, multiple air outlet channels are set to correspond to the multiple air outlets 13, and the multiple air outlet channels can be part of the air outlet channels corresponding to the first heating unit 4, or all the air outlet channels can be corresponding to the first heating unit 4, so as to flexibly adjust the defog efficiency of the lens 2.

[0086] In one embodiment, see Figure 2 and 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 .

[0087] 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.

[0088] 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 .

[0089] 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.

[0090] 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;

[0091] 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.

[0092] 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.

[0093] 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.

[0094] An embodiment of the present application provides a vehicle, which includes the above-mentioned rearview mirror.
