Description

Technical Field

[0001] This application relates to the field of rearview mirror technology, and more particularly to a rearview mirror and a vehicle. Background Technology

[0002] The camera in the electronic rearview mirror generates a lot of heat when it is working, which can cause the camera to overheat. If the camera is in an overheated state for a long time, it will fail and shorten its lifespan. Summary of the Invention

[0003] This application provides a rearview mirror and vehicle to address the problem that the camera in the electronic exterior rearview mirror is constantly overheating, thus shortening its service life.

[0004] This application provides a rearview mirror, which includes a housing and a guide member. The housing has a mounting cavity for accommodating a component to be cooled. The housing has a windward side with a wind inlet that communicates with the mounting cavity. The guide member is located within the mounting cavity and has a guide channel. The air inlet of the guide channel communicates with the wind inlet, and the air outlet of the guide channel faces the component to be cooled. The air outlet and the air inlet are at least partially offset in the direction of gravity.

[0005] This application also provides a vehicle, including a body, a door, and the aforementioned rearview mirror, wherein the rearview mirror is connected to the body or the door.

[0006] The rearview mirror of this application, by setting an air inlet on the windward side of the housing, allows more airflow to enter the mounting cavity from the air inlet. After entering the mounting cavity, the airflow is divided by a guide component. The air inlet and outlet of the guide component are offset in the direction of gravity, so that as the airflow flows from the air inlet to the air outlet, the liquid carried by the airflow flows along the inner wall of the guide channel under its own gravity and separates from the gas. The separated gas is then blown toward the component to be cooled, thereby achieving heat dissipation of the component and preventing overheating during operation, which would shorten the service life of the component. In addition, the gas formed after the airflow completes the gas-liquid separation and is blown toward the component to be cooled, can also reduce the risk of accidents such as short circuits.

[0018] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0019] The following description will refer to the accompanying drawings to provide a more complete picture of the present application. The drawings illustrate exemplary embodiments of the present application. However, the present application may be implemented in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. These exemplary embodiments are provided to make the present application thorough and complete, and to fully convey the scope of the present application to those skilled in the art. The same reference numerals denote the same or similar components.

[0020] The terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to limit the application. As used herein, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” are intended to also include the plural forms. Furthermore, when used herein, “comprising” and / or “including” and / or “having,” integers, steps, operations, components, and / or components, but does not exclude the presence or addition of one or more other features, regions, integers, steps, operations, components, and / or groups thereof.

[0021] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. Furthermore, unless expressly defined herein, terms such as those defined in a general dictionary should be interpreted as having the same meaning as they have in the relevant art and in the content of this application, and will not be interpreted as having an idealized or overly formal meaning.

[0022] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, this embodiment provides a vehicle 200, including a body 10, a door 60 and a rearview mirror 100. The door 60 is movably connected to the body 10, and the rearview mirror 100 is connected to either the body 10 or the door 60.

[0024] like Figures 3 to 6As shown, this embodiment provides a rearview mirror 100, including a housing 30 and a guide member 41. The housing 30 has a mounting cavity 303 for housing a component 20 to be cooled. The component 20 can be a camera or other imaging structure capable of capturing images of the environment surrounding the vehicle 200 and uploading these images to a display screen inside the vehicle for viewing by the occupants. Along the forward direction of the vehicle 200, the housing 30 has a windward side P with a wind inlet 301 connected to the mounting cavity 303. Specifically, the windward side P of the housing 30 refers to the side of the housing 30 closer to the front of the vehicle along its length, ensuring that airflow always enters the mounting cavity 303 from the wind inlet 301 to cool the component 20 during the vehicle's forward movement.

[0025] The flow guide 41 is located inside the mounting cavity 303 and has a flow guide channel 43. The air inlet 411 of the flow guide channel 43 is connected to the air inlet 301. The flow guide channel 43 can separate part of the gas and the liquid it carries in the gas entering it. The air outlet 412 of the flow guide channel 43 is set towards the component to be cooled 20, and the air outlet 412 and the air inlet 411 are at least partially offset in the direction of gravity to blow the separated gas toward the component to be cooled 20. The drain outlet 413 of the flow guide channel 43 is used to guide the liquid out of the outer casing 30.

[0026] Thus, the rearview mirror 100 of this application, by setting an air inlet 301 on the windward side P of the housing 30, allows more airflow to enter the mounting cavity 303 from the air inlet 301. After entering the mounting cavity 303, the airflow is diverted by the guide 41. The air inlet 411 and the air outlet 412 of the guide 41 are offset in the direction of gravity, so that as the airflow flows from the air inlet 411 to the air outlet 412, the liquid carried by the airflow flows along the inner wall of the guide channel 43 under its own gravity and separates from the gas. The separated gas is then blown toward the heat dissipation component 20, thereby achieving heat dissipation of the heat dissipation component 20 and preventing the heat dissipation component 20 from overheating during operation, which would shorten the service life of the heat dissipation component 20. In addition, the gas formed after the airflow completes the gas-liquid separation and is blown toward the heat dissipation component 20 can also reduce the risk of accidents such as short circuits.

[0027] For ease of reading, this application introduces a first direction X, a second direction Y, and a third direction Z to describe the embodiments of this application. The first direction X, the second direction Y, and the third direction Z can be three non-parallel straight lines in space; further, the first direction X, the second direction Y, and the third direction Z can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction X is described as the X-axis direction of the three-dimensional coordinate system, the second direction Y as the Y-axis direction of the three-dimensional coordinate system, and the third direction Z as the Z-axis direction of the three-dimensional coordinate system. The first direction X is parallel to the length direction of the vehicle 200, the second direction Y is parallel to the width direction of the vehicle 200, and the third direction Z is parallel to the height direction of the vehicle 200.

[0028] Please combine Figures 3 to 10 In one embodiment, the outer shell 30 includes a first shell 31 and a second shell 32, the first shell 31 and the second shell 32 are detachably connected, and the first shell 31 and the second shell 32 together enclose an installation cavity 303.

[0029] The first housing 31 is generally L-shaped and includes an integrally formed first housing portion 311 and a second housing portion 312. The second housing portion 312 is perpendicular to the first housing portion 311, and the first housing portion 311 is positioned along a second direction Y. Along a first direction X, the second housing portion 312 is integrally formed on the side of the first housing portion 311 near the rear of the vehicle. The shape of the second housing 32 is the same as that of the first housing 31, and the second housing 32 covers the top surface of the first housing 31.

[0030] Along the third direction Z, the top surface of the first housing 31 is provided with a first sub-cavity 3031, and the bottom surface of the second housing 32 is provided with a second sub-cavity 3032. When the first housing 31 and the second housing 32 are connected, the first sub-cavity 3031 and the second sub-cavity 3032 communicate with each other and form an installation cavity 303.

[0031] In this embodiment, the first housing 31 and the second housing 32 are connected by a snap-fit ​​connection. The inner wall of the first housing 31 is provided with a first snap-fit ​​portion 313, and the inner wall of the second housing 32 is provided with a second snap-fit ​​portion 321, and the first snap-fit ​​portion 313 and the second snap-fit ​​portion 321 are snap-fitted together.

[0032] The second latching portion 321 is approximately L-shaped and capable of elastic deformation. A portion of the second latching portion 321 is integrally formed into the second housing 32 along the first direction X, while another portion is spaced apart from the inner wall of the second housing 32 along the third direction Z. A latching groove 3210 is formed on the portion of the second latching portion 321 along the third direction Z. The cross-section of the first latching portion 313 is approximately a right-angled triangle, and its top surface is inclined. This inclined surface supports the second latching portion 321, guiding it to gradually tilt along the third direction Z until it extends into the latching groove 3210, thus achieving latching between the first latching portion 313 and the second latching portion 321.

[0033] It is understood that there are multiple first latching portions 313 and multiple second latching portions 321, with each of the multiple first latching portions 313 corresponding to one of the multiple second latching portions 321. The multiple first latching portions 313 are distributed at intervals around the inner wall of the first housing 31, and the multiple second latching portions 321 are distributed at intervals around the inner wall of the second housing 32.

[0034] Please combine Figures 4 to 7 In one embodiment, the rearview mirror 100 further includes a mounting member 50, which is located in the mounting cavity 303 and is detachably connected to the housing 30. The mounting member 50 is used to mount the air guide 41 and the heat dissipation component 20.

[0035] The shape of the mounting member 50 is adapted to the shape of the first housing 31, that is, the mounting member 50 is also approximately "L" shaped. The mounting member 50 is located inside the first sub-cavity 3031, and the mounting member 50 is detachably connected to the first housing 31.

[0036] Specifically, the inner wall of the first sub-cavity 3031 is provided with a plurality of connecting portions 314. Along the third direction Z, the plurality of connecting portions 314 are spaced apart from the bottom wall of the first sub-cavity 3031. The mounting member 50 is clamped between the bottom wall of the first sub-cavity 3031 and the plurality of connecting portions 314 to limit the position of the mounting member 50. The connecting portions 314 and the mounting member 50 can be connected by fasteners such as bolts, thereby realizing a detachable connection between the mounting member 50 and the first housing 31.

[0037] In this embodiment, one end of the mounting member 50 is exposed outside the housing 30, and the end of the mounting member 50 exposed outside the housing 30 is used to connect to the vehicle body 10 or the door 60.

[0038] Along the second direction Y, the first housing 31 has a first opening 3041 at one end near the vehicle body 10, and the second housing 32 has a second opening 3042 at one end near the vehicle body 10. The first opening 3041 and the second opening 3042 communicate to form a through opening 304, which communicates with the mounting cavity 303. Along the third direction Z, the mounting member 50 has a sealing part 51 protruding on one side near the second housing 32. The sealing part 51 is located inside the mounting cavity 303 and is positioned near the through opening 304. The shape and size of the sealing part 51 are adapted to the through opening 304 so that the outer peripheral surface of the sealing part 51 abuts against the inner peripheral wall of the mounting cavity 303 to close the through opening 304.

[0039] Along the second direction Y, the sealing portion 51 has a plurality of connecting protrusions 511 protruding on the side near the vehicle body 10, and the plurality of connecting protrusions 511 all protrude along the second direction Y. The ends of the plurality of connecting protrusions 511 away from the sealing portion 51 pass through the through opening 304 and connect to the vehicle body 10, thereby realizing the connection between the mounting part 50 and the vehicle body 10.

[0040] In this embodiment, along the third direction Z, the bottom wall of the first housing 31 protrudes with a first mounting portion 316, and the top wall of the second housing 32 protrudes with a second mounting portion 322. Along the second direction Y, the first mounting portion 316 and the second mounting portion 322 are attached to the side of the sealing portion 51 closest to the vehicle body 10. Furthermore, both the first mounting portion 316 and the second mounting portion 322 can be detachably connected to the sealing portion 51 by bolts, thereby achieving a detachable connection between the mounting member 50 and the first housing 31 and the second housing 32, improving the connection stability of the mounting member 50.

[0041] Please combine Figures 4 to 7 In one embodiment, the heat dissipation component 20 is located in the region of the first sub-cavity 3031 corresponding to the second shell portion 312, and the flow guide 41 is located in the region of the first sub-cavity 3031 corresponding to the corner portion of the first shell 31.

[0042] Along the first direction X, a first mounting port 3051 is provided at the end of the second housing 312 away from the first housing 311, and a second mounting port 3052 is provided at the position corresponding to the first housing 31 on the second housing 32. The first mounting port 3051 and the second mounting port 3052 communicate with each other to form a mounting port 305. At least part of the heat dissipation component 20 can be exposed to the outer casing 30 through the mounting port 305, thereby realizing the function of photographing the environment around the vehicle 200.

[0043] In this embodiment, the heat dissipation component 20 includes a camera element 21 and a connecting wire 22. Along the second direction Y, camera fixing portions 212 protrude from opposite sides of the camera element 21. Along the third direction Z, two mounting protrusions 52 protrude from the side of the mounting component 50 near the second housing 32. The two camera fixing portions 212 are correspondingly provided with the two mounting protrusions 52, and the camera fixing portions 212 and their corresponding mounting protrusions 52 abut against each other in the first direction X. The camera fixing portions 212 and their corresponding mounting protrusions 52 are connected by fasteners such as bolts, thereby achieving a detachable connection between the camera element 21 and the mounting component 50.

[0044] Along the first direction X, one end of the imaging component 21 is designated as an imaging end 211, which extends into the mounting opening 305 and is exposed outside the housing 30 through the mounting opening 305 to capture images of the surrounding environment. A wire hole 510 is provided in the sealing portion 51, which passes through the sealing portion 51 along the second direction Y. Along the first direction X, one end of the connecting wire 22 is connected to the end of the imaging component 21 furthest from the imaging end 211, and the other end of the connecting wire 22 passes through the wire hole 510 and is exposed outside the housing 30, so that the end of the connecting wire 22 furthest from the imaging component 21 can be electrically connected to other electrical components of the vehicle 200, thereby realizing functions such as power supply or signal transmission.

[0045] In this embodiment, the outer casing 30 is provided with an exhaust port 306, which is connected to the mounting cavity 303, and the exhaust port 306 can guide the airflow that has completed heat exchange with the heat-dissipating component 20 to exit the mounting cavity 303.

[0046] In some implementations, the exhaust vent 306 may be located on the end face of the second housing portion 312 away from the first housing portion 311. Alternatively, the exhaust vent 306 may be located on one or both side walls of the second housing portion 312 in the second direction Y. Alternatively, the exhaust vent 306 may be located on one or both side walls of the second housing portion 312 in the third direction Z.

[0047] In other embodiments, the exhaust port 306 may also be located at the mounting port 305. For example, the diameter of the mounting port 305 is larger than the outer diameter of the imaging end 211, thereby forming a gap between the wall of the mounting port 305 and the outer peripheral surface of the imaging end 211. This gap is the exhaust port 306, allowing airflow to be discharged from the gap between the wall of the mounting port 305 and the outer peripheral surface of the imaging end 211.

[0048] Furthermore, along the first direction X, a temperature detection element 23 is provided on the side of the imaging element 21 near the guide element 41. The temperature detection element 23 is a temperature sensor, and it can monitor the temperature of the imaging element 21 in real time. When the temperature detection element 23 detects that the temperature of the imaging element 21 is high, it will feed back the temperature signal to the ECU (electronic control unit) to issue an alarm.

[0049] Please combine Figures 3 to 7 In one embodiment, the flow guide 41 is detachably connected to the mounting member 50. The mounting member 50 has a clearance opening 53 at its corner, and the flow guide 41 is located within the space formed by the opening wall of the clearance opening 53 and the inner wall of the first housing 31.

[0050] Along the first direction X, the first housing 311 has multiple air inlets 301 on the side away from the second housing 312, and the positions of the air inlets 301 correspond to the positions of the air guides 41. Correspondingly, the second housing 32 also has multiple air inlets 301 at the positions corresponding to the air guides 41. Along the first direction X, the side of the air guide 41 away from the heat dissipation component 20 abuts against the first housing 31 and the second housing 32, thereby directly connecting the air inlet 411 and the air inlets 301, ensuring that the airflow entering from the air inlets 301 directly enters the air inlet 411.

[0051] Along the first direction X, two flow guiding and fixing portions 416 protrude from the side of the flow guide 41 near the heat dissipation component 20. Along the second direction Y, the two flow guiding and fixing portions 416 are spaced apart. The two flow guiding and fixing portions 416 extend above the mounting component 50, and abut against each other in the third direction Z, thereby limiting the position of the mounting component 50. Furthermore, both flow guiding and fixing portions 416 can be detachably connected to the mounting component 50 using fasteners such as bolts.

[0052] Along the second direction Y, limiting portions 415 are protruding on both opposite sides of the flow guide 41, and each limiting portion 415 has a limiting hole 4150. Along the first direction X, the limiting hole 4150 passes through the limiting portion 415, and the first shell portion 311 has two limiting protrusions 315. The two limiting protrusions 315 are correspondingly arranged with the two limiting portions 415, and the two limiting protrusions 315 respectively pass through the limiting hole 4150 of their corresponding limiting portions 415, thereby achieving the limiting between the first shell 31 and the flow guide 41.

[0053] In this embodiment, the flow channel 43 includes a first section 431, a second section 432 and a third section 433. One end of the first section 431 is set as an air inlet 411, and the other end of the first section 431 is connected to the second section 432. The other end of the second section 432 away from the first section 431 is set as a drain outlet 413. One end of the third section 433 is connected to the second section 432, and the other end of the third section 433 is set as an air outlet 412.

[0054] The guide member 41 is generally square in shape. Along the first direction X, the air inlet 411 is located on the side of the guide member 41 away from the imaging component 21, and the air outlet 412 is located on the side of the guide member 41 closer to the imaging component 21. This allows the airflow leaving the air outlet 412 to blow directly along the first direction X towards the imaging component 21 and the area where the connecting line 22 connects to the imaging component 21, thereby achieving heat dissipation for the imaging component 21 and the connecting line 22. Along the third direction Z, the drain outlet 413 is located on the bottom end face of the guide member 41. In addition, along the third direction Z, the first housing 31 has a water outlet 302 on the side away from the second housing 32, and the water outlet 302 connects to the first sub-cavity 3031. The bottom end face of the guide member 41 abuts against the first housing 31 so that the drain outlet 413 and the water outlet 302 are directly connected, ensuring that the liquid discharged from the drain outlet 413 can flow directly to the water outlet 302.

[0055] It is understood that in other embodiments, specific details can be found in the references. Figure 7 The air guide 41 can also be integrally formed with the housing 30, thus eliminating the need for installation of the air guide 41 and improving the assembly efficiency of the rearview mirror 100. Specifically, the air guide 41 can be formed by protruding from the inner wall of the second housing 32, and the air inlet 301 extends inward from the outer wall of the second housing 32 to connect to the first section 431, so that the air inlet 301 can serve as the air inlet 411 of the air guide channel 43, thereby increasing the flow rate of the air entering the air guide channel 43.

[0056] It is worth noting that, in this case, the portion of the guide member 41 extending beyond the second housing 32 along the third direction Z is attached to the first housing 31.

[0057] In this embodiment, a guide surface M is formed in the guide channel 43. The guide surface M is used to guide the airflow from the air inlet 411 to the air outlet 412. The guide surface M is at least partially inclined to the direction of the airflow flowing towards the air inlet 411, so that the airflow entering the guide channel 43 from the air inlet 411 is guided by the guide surface M, thereby changing the direction of the airflow and flowing towards the air outlet 412, so as to separate the rainwater and other liquids carried in the airflow.

[0058] In this embodiment, the first segment 431 and the second segment 432 are inclined to each other, and the third segment 433 and the second segment 432 are inclined to each other.

[0059] Specifically, along the first direction X, the first segment 431 extends from the side of the guide member 41 away from the imaging member 21 toward the imaging member 21, and the extension length of the first segment 431 is less than the thickness of the guide member 41. The second segment 432 is located inside the imaging member 21, and the second segment 432 extends upward along the third direction Z from the bottom surface of the guide member 41 until the second segment 432 connects with the first segment 431. The guide surface M is an arc surface, and the guide surface M is the groove wall corresponding to the corner structure formed at the connection between the first segment 431 and the second segment 432, so that the flow direction of the airflow entering the first segment 431 along the first direction X is adjusted to be parallel to the third direction Z by the guide surface M, and the airflow after the adjustment flows to the second segment 432. Along the first direction X, the third segment 433 extends from the side of the guide member 41 close to the imaging member 21 toward the side away from the imaging member 21 until the third segment 433 connects with the second segment 432.

[0060] Furthermore, along the direction of gravity (i.e., along the third direction Z), the height of the air inlet 411 is higher than that of the air outlet 412, and the height of the air outlet 412 is higher than that of the drain outlet 413.

[0061] Thus, after the airflow enters the second section 432 from the first section 431, turbulence will form because the first section 431 and the second section 432 are perpendicular to each other. The water and other liquids carried in the airflow flow towards the drain outlet 413 in the third direction Z under the action of their own gravity. When the airflow passes through the opening connecting the third section 433 and the second section 432, part of the airflow can flow towards the third section 433, and then be blown towards the photographing component 21 through the air outlet 412.

[0062] Specifically, a waterproof and breathable membrane can be installed in the third section 433 to further ensure that the airflow leaving from the air outlet 412 does not carry water or other liquids.

[0063] It is understood that in other embodiments, specific details can be found in the references. Figure 8 Along the direction of gravity (i.e., along the third direction Z), the height of the air inlet 411 is lower than that of the air outlet 412, and the height of the air inlet 411 is higher than that of the drain outlet 413. This structural design also allows for the staggered setting of the air inlet 411 and the air outlet 412 in the third direction Z, so that during the process of airflow from the air inlet 411 to the air outlet 412, the rainwater and other liquids carried by the airflow can also be diverted by their own gravity and flow to the drain outlet 413.

[0064] In this embodiment, the multiple air inlets 411 are arranged in two groups along the third direction Z, with the two groups of air inlets 411 spaced apart, and the two groups of air inlets 411 are respectively corresponding to the air inlets 301 on the first housing 31 and the second housing 32. Along the second direction Y, each group of air inlets 411 includes multiple air inlets 411 arranged sequentially at intervals. In addition, multiple air inlets 411 in one group of air inlets 411 are alternately arranged with multiple air inlets 411 in the other group of air inlets 411 in the second direction Y, thereby enabling the multiple air inlets 411 to cover more areas of the guide member 41 and increasing the air intake volume.

[0065] Accordingly, based on the number of air inlets 411, a corresponding number of first sections 431, second sections 432, third sections 433, air outlets 412, and drain outlets 413 are provided. Furthermore, the multiple air outlets 412 are arranged in two groups, spaced apart along the third direction Z. Along the second direction Y, each group of air outlets 412 includes multiple air outlets 412 arranged at intervals. Moreover, multiple air outlets 412 in one group and multiple air outlets 412 in another group are alternately arranged along the second direction Y, thereby allowing the multiple air outlets 412 to cover a larger area of ​​the air guide 41, increasing the air outlet area. Multiple drain outlets 413 are located in the same row, and the multiple drain outlets 413 are arranged at intervals along the second direction Y to avoid increasing the risk of leakage due to an increased drainage area.

[0066] In this embodiment, along the third direction Z, the diameter of the upper set of air inlets 411 is larger than the diameter of the lower set of air inlets 411. Correspondingly, the dimensions of the first section 431, the second section 432, the third section 433, the air outlet 412, and the drain outlet 413 correspond to the dimensions of the air inlets 411 they are connected to.

[0067] Thus, the larger diameter of the upper set of air inlets 411 allows for more airflow, thereby increasing the airflow volume. With more airflow, more liquids such as water are carried. The longer length of the second section 432 corresponding to the larger diameter air inlet 411 allows more water carried by the airflow to be guided through the second section 432 and discharged from the drain outlet 413. Conversely, the shorter length of the second section 432 corresponding to the smaller diameter air inlet 411 results in too much airflow entering, preventing the water from being guided to the drain outlet 413 as effectively as possible.

[0068] In this embodiment, the rearview mirror 100 further includes a filter element 42, which is used to filter impurities in the air entering from the air inlet 301. The filter element 42 can be a baffle with multiple mesh openings 420 to block impurities in the airflow such as dust or flying insects.

[0069] The flow guide 41 is provided with a mounting groove 414, and the filter element 42 is located in the mounting groove 414. The mounting groove 414 is connected to the flow guide channel 43, and is used to filter the gas passing through the flow guide channel 43 by the filter element 42. Along the third direction Z, the mounting groove 414 extends downward from the top surface of the flow guide 41, and the extension length of the mounting groove 414 is less than the height of the flow guide 41. Along the first direction X, the mounting groove 414 is located approximately at the middle position of the first section 431, and the mounting groove 414 is located on the side of the plurality of second sections 432 away from the camera element 21, so that the airflow entering each first section 431 is filtered by the filter element 42 before entering the second section 432.

[0070] It is worth noting that when the filter element 42 needs to be disassembled and cleaned, since the mounting part 50 is connected to the body 10 and the first housing 31 and the second housing 32 are connected to the mounting part 50, the filter element 42 can be cleaned by only disassembling and assembling the second housing 32, without having to remove the mounting part 50 from the body 10, thus improving cleaning efficiency.

[0071] It is understood that in other embodiments, specifically as follows: Figure 7 As shown, when the guide member 41 and the second housing 32 are integrally formed, the side of the guide member 41 near the second housing 32 adopts a concave design to directly form an installation space (i.e., the aforementioned installation groove 414) between the guide member 41 and the inner wall of the second housing 32 for the filter member 42 to be installed. This eliminates the need for a side plate structure between the filter member 42 and the second housing 32, simplifying the overall structure of the rearview mirror 100. In this embodiment, the guide member 41 may have an opening in the second direction Y for placing and removing the filter member 42.

[0072] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the scope of this application. All such changes and substitutions fall within the scope defined by this application.
