Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a rearview mirror and a vehicle having the same. BACKGROUND

[0002] The rearview mirror is an important safety component on a vehicle, which can help the driver to conveniently observe the situation behind, on the side and below the vehicle, expand the field of view, and ensure driving safety. In particular, when the driving route is about to change, such as parking, starting, turning, U-turn, etc., the driver can observe the rearview mirror to understand the real-time road conditions in time and effectively avoid traffic accidents.

[0003] A rearview mirror with a slow-moving lamp has been developed in the prior art to enhance the lighting effect when the driver observes the rearview mirror in a specific situation. The slow-moving lamp is a lamp that provides auxiliary lighting for the side of the vehicle when the vehicle is moving slowly, which should be turned on when the low beam or high beam is turned on, and is allowed to be automatically turned on when the vehicle is moving slowly until the vehicle speed reaches 10km / h if any of the following conditions is met: (1) after the engine (propulsion system) is started manually, before the vehicle is started for the first time; (2) when the reverse gear is in the fitting state; (3) the camera for assisting the parking operation system is turned on.

[0004] In addition, the national standard GB 4785-2019 "Installation Regulations for External Lighting and Light Signaling Devices of Motor Vehicles and Trailers" makes the following mandatory requirements for the visual detection of the slow-moving lamp, i.e. the observer should not be able to directly see the viewing surface of the lamp within the specified area boundary range (the area is composed of a transverse plane 10m in front of the vehicle, a transverse plane 10m behind the vehicle, and two longitudinal planes 10m on both sides of the vehicle, with a height of 1m-3m). In order to obtain good lighting effect, the power and light intensity of the slow-moving lamp in the prior art are designed to be larger and larger. In order to meet the mandatory requirements of the above visual detection, a large gap needs to be left between the viewing surface of the slow-moving lamp and the mounting surface of the rearview mirror, and some vehicles block the light by arranging protruding structures on the mounting surface of the rearview mirror. These methods will cause the NVH (Noise, Vibration, Harshness) performance of the rearview mirror to decline, which greatly affects the driving experience of the user.

[0005] Therefore, there is a need in the art for a new technical solution to solve the above problems. SUMMARY

[0006] To solve the technical problem of poor NVH performance of the rearview mirror with a slow-moving light in the prior art, the present application provides a rearview mirror. The rearview mirror comprises a rearview mirror housing having a mounting surface, and a slow-moving light assembly arranged in the rearview mirror housing and comprising a light source, an inner lens having a viewing surface facing the light source, and a non-textured outer shroud arranged in the mounting surface and having an outer surface away from the inner lens, wherein the minimum distance between the viewing surface and the mounting surface is greater than a first preset distance, and the outer surface is recessed from the mounting surface and the maximum distance therebetween is less than or equal to a second preset distance.

[0007] In the rearview mirror of the present application, a rearview mirror housing and a slow-moving light assembly are included. The rearview mirror housing has a mounting surface. It should be noted that since the rearview mirror housing is a three-dimensional structure, in this article, the "mounting surface" refers to a certain specific plane or curved surface of the rearview mirror housing. The slow-moving light assembly is arranged in the rearview mirror housing to provide sufficient illumination for the driver to observe the rearview mirror. The slow-moving light assembly includes a light source, an inner lens, and an outer shroud. The inner lens has a viewing surface facing the light source, and the outer shroud is non-textured, so that the "viewing surface" defined in visual detection can ignore the influence of the outer shroud. The outer shroud is arranged in the mounting surface and has an outer surface away from the inner lens. Among them, the minimum distance between the viewing surface and the mounting surface is greater than the first distance to meet the mandatory requirements of the national standard in visual detection (i.e. the observer cannot directly see the viewing surface when moving within the specified area boundary range). In addition, the outer surface is recessed from the mounting surface and the maximum distance therebetween is less than or equal to the second preset distance, so that the outer shroud and the rearview mirror housing have a small surface difference, preventing the air from generating a large vibration and noise when flowing through the rearview mirror, thereby improving the NVH performance of the rearview mirror.

[0008] In the preferred technical scheme of the rearview mirror cover, the light source is an LED lamp, and the slow driving lamp assembly further comprises a PCB board, the LED lamp is arranged on a first side of the PCB board; a lamp cup, the lamp cup has a base plate opposite to the PCB board and an outer circumferential wall extending from a back surface of the base plate towards the first side, a lamp nest recessed towards the PCB board is formed on the base plate, a light transmission hole located at the center of the lamp nest and capable of receiving the inner layer lens, and the outer layer cover is fixed on a front surface of the base plate. The light source is arranged as an LED lamp, which has the advantages of small volume, low power consumption, long service life, high brightness, low heat and the like. The PCB board can conveniently assemble the LED lamp and other components, and the integration degree is improved. The lamp cup is arranged to facilitate the connection with the PCB board, the inner layer lens and the outer layer cover. In addition, the arrangement of the lamp nest on the lamp cup can also expand the lighting range of the LED lamp, and facilitate the driver to better observe the road conditions around the vehicle through the rearview mirror.

[0009] In the preferred technical scheme of the rearview mirror cover, an inner circumferential wall extending along the circumferential edge of the light transmission hole and towards the first side is formed on the back surface, a plurality of clamping grooves spaced from each other are arranged on the inner circumferential wall, and a clamping protrusion capable of being inserted into the corresponding clamping groove is arranged on the inner layer lens. Through the above arrangement, the inner layer lens can be conveniently assembled to the lamp cup, and the assembly efficiency is improved.

[0010] In the preferred technical scheme of the rearview mirror cover, the slow driving lamp assembly further comprises a fixing frame arranged on a second side of the PCB board opposite to the first side and forming a fixed connection with the PCB board and the outer circumferential wall, respectively. The arrangement of the fixing frame can facilitate the fixed connection of the PCB board and the lamp cup.

[0011] In the preferred technical scheme of the rearview mirror cover, the fixing frame comprises a frame body and a plurality of fixing protrusions spaced from each other along the circumferential edge of the frame body, and each fixing protrusion is configured to be inserted into the corresponding fixing groove of the outer circumferential wall. Through the cooperation between the fixing protrusions and the fixing grooves, the fixing frame can be conveniently connected with the outer circumferential wall.

[0012] In the preferred technical scheme of the rearview mirror cover, the frame body surrounds a heat dissipation area around the LED lamp, and adjacent fixing protrusions together with the frame body and the outer circumferential wall surround a fixing area capable of receiving the potting glue. The frame body is arranged to surround the heat dissipation area around the LED lamp, so that the heat generated by the LED lamp can be conveniently conducted away through the PCB board. In addition, the adjacent fixing protrusions together with the frame body and the outer circumferential wall surround the fixing area capable of receiving the potting glue, so as to further improve the fixing reliability between the fixing frame and the outer circumferential wall by using the potting glue.

[0013] In the preferred technical scheme of the rearview mirror cover, the outer peripheral wall close to the LED lamp is provided with a through hole, and a breathable film for heat dissipation is arranged on the through hole. Through the above arrangement, the heat generated by the LED lamp can be further conducted out through the breathable film, preventing heat accumulation, thereby improving the service life of the LED lamp.

[0014] In the preferred technical scheme of the rearview mirror cover, the outer surface is parallel to the mounting profile. By arranging the outer surface of the outer layer cover parallel to the mounting profile of the rearview mirror, the outer surface and the mounting profile have a uniform gap, further improving the NVH performance of the rearview mirror.

[0015] In the preferred technical scheme of the rearview mirror cover, the second predetermined distance is in the range of 0-0.5mm. Through the above arrangement, the second predetermined distance has a moderate value to ensure that the rearview mirror has good NVH performance.

[0016] In the preferred technical scheme of the rearview mirror cover, the peripheral edge of the outer layer cover is parallel to the peripheral edge of the mounting profile. Through the above arrangement, the outer layer cover has a profile that is approximately the same as the mounting profile and is scaled by a certain ratio, so that the outer layer cover has a regular and aesthetic appearance when arranged on the mounting profile.

[0017] In the preferred technical scheme of the rearview mirror cover, the inner layer lens and the outer layer cover are made of PC or PMMA. Through the above arrangement, the inner layer lens and the outer layer cover have good mechanical properties and light transmission properties.

[0018] In the preferred technical scheme of the rearview mirror cover, the PCB board is an aluminum-based circuit board. The arrangement of the aluminum-based circuit board can make the PCB board have good heat dissipation performance.

[0019] In the preferred technical scheme of the rearview mirror cover, the rearview mirror further comprises a camera arranged in the rearview mirror housing and spaced apart from the slow walking lamp assembly, and the slow walking lamp assembly can provide the camera with illumination of a predetermined light intensity in a predetermined area. Through the above arrangement, the rearview mirror of the present application can conveniently observe the road conditions around the camera, expand the field of view of the driver and passenger, and further improve the driving safety. In addition, the slow walking lamp assembly is configured to provide the camera with illumination of a predetermined light intensity in a predetermined area, which can also ensure that the camera has good image shooting quality and ensures the user's experience.

[0020] In order to solve the technical problem of poor rearview mirror NVH performance of the slow-moving lamp in the prior art, the present application provides a vehicle. The vehicle comprises the rearview mirror of any one of the above. By adopting the rearview mirror of any one of the above, the vehicle of the present application can meet the mandatory requirements of the national standard for the slow-moving lamp viewing surface on the basis of providing sufficient illumination, while significantly reducing the NVH performance and improving the user's experience.

Figure 5 is a sectional view schematic diagram of an embodiment of the slow walking light assembly in the rearview mirror of the present application, obtained along the sectional line B-B shown in Figure 4 ; Figure 6 is a structural schematic diagram of an embodiment of the slow walking light assembly in the rearview mirror of the present application, with the outer protective cover removed; Figure 7 is a back view structural schematic diagram of an embodiment of the lamp cup of the slow walking light assembly in the rearview mirror of the present application; Figure 8 is a structural schematic diagram of an embodiment of the slow walking light assembly in the rearview mirror of the present application, with the outer protective cover and the lamp cup removed; Figure 9 is a structural schematic diagram of an embodiment of the slow walking light assembly in the rearview mirror of the present application, with the outer protective cover, the lamp cup and the inner lens removed.

[0057] As shown in Figures 2-9 , in one or more embodiments, the slow walking light assembly 20 includes a light emitting source 21, an inner lens 22 and an outer protective cover 23. Alternatively, the slow walking light assembly 20 also includes, but is not limited to, a PCB board 24, a lamp cup 25 and a fixing frame 26, etc.

[0058] As shown in Figure 9 , in one or more embodiments, the light emitting source 21 includes 4 LED lights 211 spaced apart from each other. The rated power of each LED light 211 can be 1 W (i.e. watt), or other suitable power higher or lower than 1 W. Alternatively, the number of LED lights 211 can also be set to other suitable number more or less than 4, as long as the light intensity of the light emitting source 21 can meet the illumination needs.

[0059] As shown in Figure 2 , Figure 5 , Figure 6 and Figure 8As shown, in one or more embodiments, the inner lens 22 comprises a substantially circular inner lens body 221 and a lens circumferential wall 222 extending perpendicularly from a circumferential edge of the inner lens body 221 towards a direction away from the inner lens body 221. The inner lens 22 (including the inner lens body 221 and the lens circumferential wall 222) can be integrally formed by an injection molding process using a suitable resin material, so as to simplify the manufacturing process. The resin material can be, but is not limited to, PC, PMMA, etc., so that the inner lens 22 has good mechanical properties and light transmission properties. As shown in Figure 2 and Figure 5 As shown, in the assembled state, the inner lens body 221 has a viewing surface 2211 facing the light emitting source 21. That is, the “viewing surface” herein refers to the inner surface of the inner lens body 221. Referring to Figure 2 In the assembled state, the minimum distance D1 between the viewing surface 2211 and the mounting surface 11 is greater than or equal to a first preset distance. It should be noted that the first preset distance can be measured by a visual detection test method. In one or more embodiments, the first preset distance is 3 mm. Alternatively, the first preset distance can also be set to other suitable settings larger or smaller than 3 mm. Through the above setting, it can be ensured that the viewing surface 2211 of the slow-moving lamp assembly 20 in the rearview mirror 1 of the present application meets the mandatory requirements of visual detection. As shown in Figure 6 and Figure 8 As shown, the inner lens body 221 is further provided with light guide structures 2212 arranged circumferentially along the inner lens body 221. Each light guide structure 2212 extends substantially in the direction of illumination (i.e., the axial direction of the inner lens body 221). The provision of the light guide structures 2212 can expand the illumination range of the light emitting source 21 to meet the design requirements. Referring to Figure 8 In one or more embodiments, the lens circumferential wall 222 is formed with three clamping protrusions 2221 spaced from each other along the circumference thereof. Each clamping protrusion 2221 is configured to form a clamping fit with a corresponding clamping groove 2531 on the inner circumferential wall 253 of the lamp cup 25, so that the inner lens 22 can be conveniently fixed on the inner circumferential wall 253 of the lamp cup 25.

[0060] As shown in Figure 2 , Figure 3 and Figure 5As shown, in one or more embodiments, the outer shroud 23 comprises an outer shroud body 231 and a shroud circumferential wall 232 extending radially outwardly along a circumferential edge of the outer shroud body 231. The outer shroud 23 (including the outer shroud body 231 and the shroud circumferential wall 232) can be integrally formed by an injection molding process using a suitable resin material, so as to simplify the manufacturing process. The resin material can be, but is not limited to, PC, PMMA, etc., so that the outer shroud 23 has good mechanical properties and light transmission properties. The outer shroud body 231 is untextured, so that the influence of the outer shroud 23 can be ignored when defining the "viewing surface" of the slow motion lamp assembly 20. The outer shroud body 231 has a fixed connection with the base plate 251 of the lamp cup 25, so that the outer shroud body 231 is arranged to cover the inner lens 22. The fixed manner includes, but is not limited to, clamping, bonding, screwing, etc. In one or more embodiments, the circumferential edge of the outer shroud body 231 is parallel to the circumferential edge of the mounting profile 11. In other words, the outer shroud body 231 has a profile that is substantially the same as and scaled by a certain ratio of the mounting profile 11, so that the overall styling of the rearview mirror housing 10 is more regular and aesthetically pleasing in the assembled state. Referring to Figure 2 , the outer shroud body 231 has an outer surface 2311 facing away from the inner lens 22. The outer surface 2311 is recessed inwardly from the mounting profile 11 into the rearview mirror housing 10, and the maximum distance D2 between the outer surface 2311 and the mounting profile 11 is less than or equal to a second preset distance. In one or more embodiments, the outer surface 2311 is parallel to the mounting profile 11. That is, the distance D2 between any position on the outer surface 2311 and the mounting profile 11 is the same. In one or more embodiments, the second preset distance is 0-0.5 mm. Alternatively, the second preset distance can also be set to other suitable values. Through the above arrangement, the outer shroud body 231 and the mounting profile 11 have a small surface difference, thereby effectively reducing the vibration and noise generated by the air flowing through the mounting gap of the outer shroud 23 and the rearview mirror housing 10, and significantly improving the NVH performance.

[0061] As shown in Figure 2 , Figure 5 , Figure 8 and Figure 9 , in one or more embodiments, the PCB board 24 is an aluminum-based circuit board, so that it has good heat conduction performance. Alternatively, the PCB board body 241 can also use other suitable circuit boards, such as a copper-based circuit board, etc. The PCB board 24 has a substantially plate-shaped PCB board body 241. The PCB board body 241 has opposite first and second side surfaces 2411 and 2412. Referring to Figure 5 , the first side surface 2411 faces the inner lens 22, and the second side surface 2412 faces away from the inner lens 22. Referring to Figure 8 and Figure 9In the assembled state, the inner lens 22 covers all the LED lamps 211 so that the light generated by the LED lamps 211 can be emitted after passing through the inner lens 22. In addition, a plurality of components 242 are arranged on the first side 2411 of the PCB board body 241 and spaced apart from the LED lamps 211. The components 242 are electrically connected with the LED lamps 211 to control the operation of the LED lamps 211. In addition, the components 242 are electrically connected with the power connection 28 arranged on the second side 2412 of the PCB board body 241 to be connected with an external power supply through the power connection 28, so as to provide power for the LED lamps 211. The components 242 can be, but are not limited to, resistors, rectifier bridges, control chips, etc. In one or more embodiments, two pins (not shown in the figure) are arranged on each LED lamp 211 in addition to the positive and negative electrodes, and the two pins are configured to be connected with an aluminum plate (not shown in the figure) outside the PCB board body 241, so as to transfer part of the heat generated by the LED lamps 211, thereby further improving the heat dissipation efficiency.

[0062] As shown in Figures 2-7 In one or more embodiments, the lamp cup 25 includes a base plate 251, an outer circumferential wall 252, and an inner circumferential wall 253, etc. The lamp cup 25 can be integrally formed by injection molding using a suitable resin material, so as to simplify the manufacturing process. The resin material can be, but is not limited to, PP, PC, etc. Alternatively, the lamp cup 25 can also be processed using a suitable metal material such as aluminum. The base plate 251 has a substantially plate-shaped base plate body 2511. The base plate body 2511 has opposite front and back surfaces. In the assembled state, the back surface of the base plate body 2511 is opposite to the first side 2411 of the PCB board 24, and the front surface of the base plate body 2511 is away from the first side 2411 of the PCB board 24. A lamp nest 2512 recessed towards the PCB board 24 is formed in the middle of the base plate body 2511. A substantially circular light transmission hole 2513 is arranged at the center of the lamp nest 2512. The light transmission hole 2513 is configured to receive the inner lens 22. That is, the inner lens body 221 of the inner lens 22 is arranged in the light transmission hole 2513. In addition, the outer cover 23 is fixed to the front surface of the base plate body 2511 and covers the lamp nest 2512. In other words, the outer cover 23 also covers the light transmission hole 2513 and the inner lens 22 arranged in the light transmission hole 2513. Therefore, the light generated by the LED lamps 211 will pass through the inner lens 22, the lamp nest 2512, and the outer cover 23 in sequence, so as to obtain the illumination range and brightness that meet the design requirements.

[0063] Continuing to refer to Figures 2-7The outer circumferential wall 252 is configured to extend from the back surface of the substrate body 2511 towards the first side surface 2411 of the PCB board 24. In one or more embodiments, seven fixing grooves 2521 are formed on the inner side of the outer circumferential wall 252 and are spaced apart from each other. Each fixing groove 2521 is configured to receive a corresponding fixing protrusion 262 on the fixing frame 26, so that the fixing frame 26 can be conveniently fixed on the lamp cup 25. Alternatively, the number of fixing grooves 2521 can also be set to other suitable numbers more or less than seven, such as six, eight, etc. In one or more embodiments, a substantially circular through hole 2522 is also provided on the outer circumferential wall 252 close to the LED lamp 211. A breathable film 2523 for heat dissipation is provided on the through hole 2522 to further improve the heat dissipation efficiency. The breathable film 2523 can be, but is not limited to, ePTFE (i.e. polytetrafluoroethylene), PE, TPU, etc.

[0064] Continuing to refer to Figure 4 , Figure 6 and Figure 7 , in one or more embodiments, two mounting lugs 254 are provided on the outer side of the outer circumferential wall 252 and are spaced apart from each other. One substantially circular mounting hole 2541 is provided on each mounting lug 254. The mounting hole 2541 is configured to be matched with a suitable fastener (such as a bolt, screw, nut, etc.) so as to fix the lamp cup 25 in the rearview mirror 1. Alternatively, the mounting hole 2541 can also be set to a regular hexagon or other suitable shape. Alternatively, the mounting lugs 254 can also be set to three, four or other suitable numbers.

[0065] Continuing to refer to Figure 7 , the inner circumferential wall 253 is positioned on the back surface of the substrate body 2511 and is located in the middle of the outer circumferential wall 252. Specifically, the inner circumferential wall 253 is configured to extend along the circumferential edge of the light transmission hole 2513 and towards the first side surface 2411 of the PCB board 24. In one or more embodiments, three clamping grooves 2531 are formed on the inner circumferential wall 253 and are spaced apart from each other. Each clamping groove 2531 is configured to receive a corresponding clamping protrusion 2221 in the inner lens 22, so that the inner lens 22 can be conveniently fixed on the lamp cup 25. Alternatively, the number of clamping grooves 2531 can also be set to other suitable numbers more or less than three, such as two, four, etc. Referring to Figures 7-9 In the assembled state, the inner lens 22 fixed on the inner circumferential wall 253 covers all the LED lamps 211, and other components 242 spaced apart from the LED lamps 211 are shielded by the inner circumferential wall 253. That is, the area enclosed by the inner circumferential wall 253 and the outer circumferential wall 252 covers the components 242. Through the above arrangement, the user can see at most the LED lamps 211 but not the other components 242 through the outer cover 23 and the inner lens 22, so as to achieve an aesthetic effect.

[0066] like Figure 4 and Figure 5 As shown, in one or more embodiments, the fixing frame 26 is arranged on the second side 2412 of the PCB board 24 and configured to be connected to the outer peripheral wall 252 of the PCB board 24 and the lamp cup 25, respectively. The fixing frame 26 can be integrally molded using a suitable resin material through injection molding to simplify the manufacturing process. The resin material can be, but is not limited to, PP, PE, etc. In one or more embodiments, the fixing frame 26 includes a frame body 261 and seven fixing protrusions 262 spaced apart from each other along the circumferential edge of the frame body 261. Each fixing protrusion 262 is configured to be inserted into a corresponding fixing groove 2521 in the outer peripheral wall 252 of the lamp cup 25. In one or more embodiments, the frame body 261 surrounds a heat dissipation area 2611 surrounding the LED lamp 211. In other words, all LED lamps 211 located on the first side 2411 of the PCB board 24 fall within the area surrounded by the frame body 261 located on the second side 2412 of the PCB board 24. With the above configuration, the heat generated by the LED lamp 211 can be directly transferred away from the heat dissipation area 2611 through the PCB board 24, ensuring heat dissipation effect. In one or more embodiments, the frame body 261 encloses two spaced-apart heat dissipation areas 2611, one of which is matched with the LED lamp 211, and the other is matched with other components 242, to further improve the heat dissipation effect. In addition, any two adjacent fixing protrusions 262 together with the frame body 261 and the outer peripheral wall 252 form a fixing area 263. A potting compound 27 is arranged in each fixing area 263, so that the outer peripheral wall 252, the fixing frame 26, and the PCB board 24 form a firm and stable fixed connection. The potting compound 27 can be, but is not limited to, polyurethane potting compound, silicone potting compound, or epoxy resin potting compound. Alternatively, the fixing frame 26 can also be configured to form a fixed connection with the PCB board 24 and the lamp cup 25 in other suitable ways.
