Technical Field
[0001] This invention relates to the field of vehicles, and more particularly to a rearview mirror assembly and a vehicle. Background Technology
[0002] Currently, vehicle rearview mirrors are generally divided into two types: physical rearview mirrors and electronic rearview mirrors. Electronic rearview mirrors are indirect vision devices that obtain a specified field of view through a system composed of cameras and monitors. Physical rearview mirrors are conventional optical rearview mirrors with optical mirrors. In actual use, electronic rearview mirrors provide a clearer field of view, making it easier for drivers to judge road conditions. However, in extreme weather conditions, the cameras of electronic rearview mirrors are easily contaminated by water mist or mud, affecting their use. Therefore, conventional physical rearview mirrors are more suitable for extreme weather conditions than electronic rearview mirrors. However, due to their larger size, physical rearview mirrors can lead to increased wind resistance and wind noise, affecting the driving experience. Summary of the Invention
[0003] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of this invention is to provide a rearview mirror assembly. The rearview mirror assembly of the invention features a rearview mirror body and a base portion that can be selectively detached, allowing the rearview mirror assembly to select a corresponding rearview mirror feedback mode according to actual environmental conditions. Furthermore, the operation of switching feedback modes is simple and convenient, thereby improving the driving experience.
[0004] The present invention also proposes a vehicle including the above-described rearview mirror assembly.
[0005] The rearview mirror assembly according to the present invention includes a base portion and a rearview mirror body. The base portion is connected to the vehicle body, a camera is disposed on the base portion, and a first snap-fit portion is formed on the base portion. The rearview mirror body is provided with an optical mirror surface, and a second snap-fit portion is formed on the rearview mirror body. The second snap-fit portion is adapted to engage with the first snap-fit portion to fix the rearview mirror body.
[0006] The rearview mirror assembly of the invention features a rearview mirror body and a base that can be selectively detached. This allows the rearview mirror assembly to choose the appropriate rearview mirror feedback method based on actual environmental conditions. For example, in good weather such as sunny days, the rearview mirror body does not need to be installed, allowing the rearview mirror assembly to directly monitor the road surface using a camera. This provides a clearer feedback of road conditions and reduces wind resistance and wind noise. In rainy or snowy weather, the rearview mirror body can be installed, using an optical mirror to monitor the road surface. This reduces the contamination of the rearview mirror assembly's field of vision by water mist and mud, improves the accuracy of the rearview mirror assembly's detection of the road environment, and thus enhances vehicle safety.
[0007] According to one embodiment of the present invention, the base portion includes a housing and a cover, wherein a receiving cavity is formed inside the housing and opens to the outside, and at least a portion of the camera is received in the receiving cavity; the cover closes the opening of the receiving cavity, and a support surface adapted to support the rearview mirror body is formed on the cover; wherein the first snap-fit portion is disposed on the cover.
[0008] According to one embodiment of the present invention, the lower end of the cover is provided with a first snap-fit portion, the first snap-fit portion is received in the receiving cavity, and a snap-fit hole through the height direction is formed in the first snap-fit portion; the second snap-fit portion extends into the snap-fit hole.
[0009] According to one embodiment of the present invention, the lower end of the first snap-fit portion is provided with an opening groove, and the second snap-fit portion is provided with a buckle that protrudes radially from the second snap-fit portion. The buckle is adapted to abut against the opening groove when the first snap-fit portion and the second snap-fit portion are engaged, so as to restrict the relative rotation between the first snap-fit portion and the second snap-fit portion.
[0010] According to one embodiment of the present invention, the buckle is constructed as a plurality of buckles corresponding one-to-one with the opening slots, and the second snap-fit portion has a plurality of deformation grooves spaced apart from each other in the circumferential direction, with each deformation groove disposed between two adjacent buckles.
[0011] According to one embodiment of the present invention, the buckle has chamfers on both sides in the width direction.
[0012] According to one embodiment of the present invention, the rearview mirror assembly further includes a sealing component disposed on the lower side of the first snap-fit portion and connected to the bottom wall of the housing.
[0013] According to one embodiment of the present invention, the sealing assembly includes a support shaft, a sealing plate, and an elastic element. The support shaft is connected to the bottom wall of the housing. The sealing plate is movably disposed at one end of the support shaft near the cover. An extension plate extending radially is formed on the sealing plate, and the extension plate can be selectively received within the opening groove. The elastic element is sleeved on the outer periphery of the support shaft and abuts against the sealing plate.
[0014] According to one embodiment of the present invention, the sealing assembly further includes an extension disposed on the underside of the sealing plate, the extension being movably sleeved on at least a portion of the outer periphery of the support shaft.
[0015] The vehicle according to the present invention is briefly described below.
[0016] The vehicle according to the present invention includes the rearview mirror assembly of the above embodiments. Since the vehicle according to the present invention is equipped with the rearview mirror assembly of the above embodiments, after the rearview mirror assembly is assembled with the vehicle, the vehicle can choose whether to assemble the rearview mirror body according to the actual environmental conditions. For example, in good weather, it is not necessary to assemble the rearview mirror body. The rearview function is realized by collecting information of the rear view of the vehicle body through the camera on the base. Moreover, not assembling the rearview mirror body can reduce the wind resistance and wind noise of the vehicle body and improve the driving experience. In extreme weather, the rearview mirror body can be assembled with the base. The rearview function is realized by collecting information of the rear view of the vehicle body through the optical mirror. This can reduce the influence of impurities such as water mist and mud on the process of collecting visual information and improve the clarity when looking behind. In addition, the overall structure of the rearview mirror assembly is simple and the operation of changing the rearview mode is convenient, which can improve the user experience of the vehicle.

[0031] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0032] Currently, vehicle rearview mirrors are generally divided into two types: physical rearview mirrors and electronic rearview mirrors. Electronic rearview mirrors are indirect vision devices that obtain a specified field of view through a system composed of cameras and monitors. Physical rearview mirrors are conventional optical rearview mirrors with optical mirrors. In actual use, electronic rearview mirrors provide a clearer field of view, making it easier for drivers to judge road conditions. However, in extreme weather conditions, the cameras of electronic rearview mirrors are easily contaminated by water mist or mud, affecting their use. Therefore, conventional physical rearview mirrors are more suitable for extreme weather conditions than electronic rearview mirrors. However, due to their larger size, physical rearview mirrors can lead to increased wind resistance and wind noise, affecting the driving experience.
[0033] The following is for reference. Figures 1-6 A rearview mirror assembly according to an embodiment of the present invention is described.
[0034] The rearview mirror assembly 1 according to the present invention includes a base portion 11 and a rearview mirror body 12. The base portion 11 is connected to the vehicle body, a camera is provided on the base portion 11, and a first snap-fit portion 113 is formed on the base portion 11. An optical mirror surface 123 is provided on the rearview mirror body 12, and a second snap-fit portion 121 is formed on the rearview mirror body 12. The second snap-fit portion 121 is adapted to snap-fit with the first snap-fit portion 113 to fix the rearview mirror body 12.
[0035] The rearview mirror assembly 1 according to the present invention includes a base portion 11 connected to the vehicle body. A camera is mounted on the base portion 11, which can monitor the road conditions behind the vehicle body in real time and transmit the monitored information to the control system inside the vehicle body. This control system can be understood as an integration of electronic devices including a digital vision processing system, a safety system, and a liquid crystal display. The camera, in conjunction with the control system inside the vehicle body, forms a complete electronic rearview mirror, enabling the driver to react promptly to road conditions. The camera improves the clarity of the rearview mirror assembly 1's monitoring of road conditions, avoiding inaccurate road information, reducing the time required for the driver to judge road conditions, and improving driving safety. Simultaneously, the camera enables the rearview mirror assembly 1 to achieve the effects of existing electronic rearview mirrors, while maintaining a small overall size, reducing wind resistance and wind noise, and improving the driving experience.
[0036] The rearview mirror assembly 1 also includes a rearview mirror body 12, on which an optical mirror 123 is provided. The optical mirror 123 can reflect the road conditions behind the vehicle. Here, the rearview mirror body 12 can be understood as a physical rearview mirror in the prior art. A first latching part 113 is provided on the base part 11, and a second latching part 121 is provided on the rearview mirror body 12. The first latching part 113 and the second latching part 121 can be selectively latched together to fix the rearview mirror body 12 to the base part 11.
[0037] It is worth noting that the fixing of the rearview mirror body 12 to the base part 11 is optional, which can also be understood as the rearview mirror and the base part 11 being detachable. Specifically, under normal weather conditions, the rearview mirror assembly 1 can use only the camera on the base part 11 as an electronic rearview mirror. At this time, the rearview mirror assembly 1 is small in size and has low wind resistance, which can improve the driving experience while meeting the rearview requirements. In extreme rain and snow weather, the camera is easily blurred by contamination. At this time, the rearview mirror body 12 can be mounted on the base part 11, so that the rearview mirror assembly 1 uses the traditional optical mirror 123 to reflect road information. At this time, the optical mirror 123 can reduce the contamination of impurities such as water mist and mud, avoid safety hazards caused by unclear road information, and improve vehicle safety.
[0038] The rearview mirror assembly 1 of the invention is provided with a rearview mirror body 12 and a base part 11 that can be selectively detached and coupled together. This allows the rearview mirror assembly 1 to select the corresponding rearview mirror feedback method according to the actual environmental conditions. For example, in good weather such as sunny days, there is no need to install the rearview mirror body 12, and the rearview mirror assembly 1 can directly use a camera to monitor the road surface, which can provide a clearer feedback of the road surface conditions and reduce wind resistance and wind noise. In rainy or snowy weather, the rearview mirror body 12 can be installed, and the optical mirror 123 can be used to monitor the road surface. This can reduce the pollution of the rearview mirror assembly 1's field of vision by water mist and mud, improve the accuracy of the rearview mirror assembly 1 in detecting the road environment, and thus improve vehicle safety.
[0039] In some embodiments, such as Figure 1 and Figure 5 As shown, the rearview mirror body 12 can be provided with a housing 122, and an optical mirror 123 can be mounted on the housing 122. The housing 122 is provided with a second locking part 121 that cooperates with the first locking part 113. During processing, a clearance groove 1221 can be designed on the housing 122, and the second locking part 121 can be disposed in the clearance groove 1221. When the rearview mirror body 12 is assembled with the base part 11, the clearance groove 1221 can avoid at least part of the base part 11.
[0040] According to one embodiment of the present invention, the base portion 11 includes a housing 111 and a cover 112. The housing 111 has an open-to-the-outside receiving cavity formed inside, and at least a portion of the camera is received in the receiving cavity. The cover 112 closes the opening of the receiving cavity, and a support surface 1121 suitable for supporting the rearview mirror body 12 is formed on the cover 112. A first snap-fit portion 113 is disposed on the cover 112.
[0041] Specifically, the base portion 11 constructs a housing 111, within which an outwardly open receiving cavity is formed. During assembly, the camera can be directly assembled into the receiving cavity through the open opening, simplifying the assembly process and preventing the exposure of electrical wiring and other structures, thus improving camera safety. A cover 112 can be provided at the open opening of the receiving cavity to seal it, preventing external dust and other impurities from entering and preventing structures on the camera from detaching from the cavity. Furthermore, a support surface 1121 can be provided on the cover 112. During assembly, the support surface 1121 can contact and support the rearview mirror body 12. The support surface 1121 increases the mating area between the base portion 11 and the rearview mirror body 12, improving the stability of the rearview mirror body 12 assembly.
[0042] According to one embodiment of the present invention, a first snap-fit portion 113 is provided at the lower end of the cover 112, the first snap-fit portion 113 is received in the receiving cavity, and a snap-fit hole 1132 through the height direction is formed in the first snap-fit portion 113; a second snap-fit portion 121 extends into the snap-fit hole 1132.
[0043] Specifically, the rearview mirror assembly 1 can have the first latching portion 113 disposed at the lower end of the cover 112, which can also be understood as the side of the cover 112 away from the support surface 1121, and the first latching portion 113 extends in the opening direction of the receiving cavity. This can be understood as the first latching portion 113 being received inside the receiving cavity after the cover 112 closes the opening of the receiving cavity. The extending direction of the first latching portion 113 allows it to be received inside the receiving cavity, reducing the volume of the base portion 11 and effectively reducing the wind resistance and wind noise of the rearview mirror assembly 1. The first snap-fit portion 113 has a snap-fit hole 1132 that extends through the height direction. This extension through the height direction can be understood as the snap-fit hole 1132 extending through the cover 112 and the first snap-fit portion 113 in sequence. During assembly, the second snap-fit portion 121 can pass through the cover 112 and be received in the snap-fit hole 1132. The snap-fit hole 1132 improves the stability of the engagement between the first snap-fit portion 113 and the second snap-fit portion 121, and also reduces the assembly difficulty between the base portion 11 and the rearview mirror body 12.
[0044] According to one embodiment of the present invention, the lower end of the first latching portion 113 is provided with an opening groove 1131, and the second latching portion 121 is provided with a buckle 1211 that protrudes radially from the second latching portion 121. The buckle 1211 is adapted to abut against the opening groove 1131 when the first latching portion 113 and the second latching portion 121 are engaged, so as to restrict the relative rotation between the first latching portion 113 and the second latching portion 121.
[0045] Since at least a portion of the second latching portion 121 can be accommodated within the latching hole 1132 of the first latching portion 113, the structure of the first latching portion 113 affects the stability of the assembly of the second latching portion 121 with the latching hole 1132. Specifically, the rearview mirror assembly 1 has an opening groove 1131 at the lower end of the first latching portion 113 that opens away from the cover 112. At the same time, the second latching portion 121 has a buckle 1211 that protrudes radially. When the end of the second latching portion 121 extends into the latching hole 1132 to a certain depth, the buckle 1211 can abut against the end face of the opening groove 1131 to limit the relative rotation between the second latching portion 121 and the first latching portion 113, thereby improving the stability of the engagement between the first latching portion 113 and the second latching portion 121, and thus improving the stability of the assembly of the rearview mirror body 12.
[0046] According to one embodiment of the present invention, the buckle 1211 is configured to be a plurality of buckles corresponding one-to-one with the opening slot 1131, and the second snap-fit portion 121 has a plurality of deformation grooves 1212 spaced apart from each other in the circumferential direction, and each deformation groove 1212 is disposed between two adjacent buckles 1211.
[0047] The rearview mirror assembly 1 has multiple opening slots 1131 and multiple latches 1211 spaced apart in the circumferential direction on the first latching part 113 and the second latching part 121, respectively. Each latch 1211 corresponds to one opening slot 1131, which improves the stability of the assembly of the first latching part 113 and the second latching part 121. The second latching part 121 also has a deformation groove 1212 between two adjacent latches 1211. The deformation groove 1212 facilitates the radial deformation of the area where the latch 1211 is located. During assembly, the area where the latch 1211 is located can deform towards the radial inward end, so that the second latching part 121 can extend into the latching hole 1132. When the second latching part 121 reaches the preset position, the inner wall of the latching hole 1132 no longer limits the latch 1211 radially. At this time, the area where the latch 1211 is located reset so that the latch 1211 can stop against the opening slot 1131. The deformation groove 1212 facilitates the assembly of the second snap-fit part 121 and the first snap-fit part 113.
[0048] According to one embodiment of the present invention, the buckle 1211 has chamfers on both sides in the width direction. For example... Figure 6 As shown, the buckle 1211 has chamfered edges on both sides in the width direction. This can be understood as the buckle 1211 gradually decreasing in width radially away from the second engaging portion 121. This design reduces the width of the buckle 1211, causing the area where the buckle 1211 is located to deform radially inward when the second engaging portion 121 is rotated under force. This allows the buckle 1211 to disengage from the opening slot 1131. After the buckle 1211 disengages from the opening slot 1131, the second engaging portion 121 can be removed from the engaging hole 1132, thus enabling the disassembly of the rearview mirror body 12 from the base portion 11. The design of reducing the width of the buckle 1211 reduces the difficulty of disassembling the rearview mirror body 12.
[0049] In some embodiments, at the location where the buckle 1211 is provided with a chamfered structure, the chamfered area, in addition to Figure 6 The inclined plane shown can also be a circular arc transition surface, etc.
[0050] According to one embodiment of the present invention, the rearview mirror assembly 1 further includes a sealing component 13, which is disposed at the lower end of the first latching portion 113 and connected to the bottom wall of the housing 111. When the rearview mirror assembly 1 is not assembled with the rearview mirror body 12, external water mist, dust, etc., can easily enter the receiving cavity through the latching hole 1132 and damage the camera. Therefore, the rearview mirror assembly 1 also provides a sealing component 13 between the first latching portion 113 and the bottom wall of the housing 111. The rearview mirror assembly 1 is located at the lower end of the first latching portion 113 and connected to the bottom wall of the housing 111. Here, the bottom wall can also be understood as the bottom wall of the receiving cavity. The sealing component 13 can seal the latching hole 1132 when the rearview mirror body 12 is not assembled, thereby improving the safety of the camera.
[0051] According to one embodiment of the present invention, the sealing assembly 13 includes a support shaft 131 and a sealing plate 132. The support shaft 131 is connected to the bottom wall of the housing 111. The sealing plate 132 is movably disposed at one end of the support shaft 131 near the cover 112. An extension plate 133 extending radially is formed on the sealing plate 132. The extension plate 133 can be selectively received in the opening groove 1131.
[0052] Specifically, the sealing assembly 13 is provided with a support shaft 131 and a sealing plate 132. The support shaft 131 is connected to the bottom wall of the housing 111, which can also be understood as the bottom wall of the receiving cavity. The sealing plate 132 is provided at the end of the support shaft 131 near the cover 112. When the sealing assembly 13 is assembled, the sealing plate 132 can be received in the snap-fit hole 1132 to seal the snap-fit hole 1132. The sealing plate 132 has radially extending extension plates 133, and the number of extension plates 133 corresponds to the number of opening slots 1131. When the base part 11 is not engaged with the rearview mirror body 12, the extension plates 133 and the opening slots 1131 abut against each other in the height direction so that the extension plates 133 can seal the gap between the opening slots 1131 and the sealing plate 132. The arrangement of the sealing plate 132 and the extension plates 133 can prevent external impurities from entering the receiving cavity through the snap-fit hole 1132 and damaging the camera, thereby improving the safety of the camera.
[0053] In addition, the sealing assembly 13 also includes an elastic element 134, which is sleeved on the outer periphery of the support shaft 131 and abuts against the sealing plate 132. During assembly, the sealing assembly 13 may also be provided with the elastic element 134, which may be a compression spring or similar structure. Specifically, the elastic element 134 may be sleeved on the outer periphery of the support shaft 131 and abut against the sealing plate 132. When the elastic element 134 is assembled, one end of the elastic element 134 abuts against the sealing plate 132, and the other end of the elastic element 134 abuts against the bottom wall of the receiving cavity, and the elastic element 134 is in a compressed state. At this time, the elastic element 134 can apply a pushing force to the sealing plate 132, so that the extension plate 133 and the opening groove 1131 are tightly fitted, further improving the sealing effect of the sealing plate 132 and the extension plate 133 on the first snap-fit portion 113.
[0054] When the rearview mirror body 12 needs to be assembled, the second snap-fit part 121 extends through the cover 112 and into the snap-fit hole 1132. The free end of the second snap-fit part 121 will push the sealing plate 132 toward the bottom wall of the receiving cavity. After the second snap-fit part 121 pushes the sealing plate 132 a certain distance, the buckle 1211 can be snapped into the gap between the extension plate 133 and the opening groove 1131 and abut against the opening groove 1131 to restrict the relative movement between the rearview mirror body 12 and the base part 11. At this time, the elastic member 134 is still in a compressed state and continues to apply a pushing force to the sealing plate 132 so that the sealing plate 132 abuts against the second snap-fit part 121, so that the sealing plate 132 can still seal the snap-fit hole 1132.
[0055] In some embodiments, a drainage channel extending in the height direction is formed in the sealing assembly 13. This can be understood as the sealing plate 132 having a drainage hole 135 at its center, the drainage hole 135 passing through the support shaft 131 in the height direction to form a drainage channel, and the base portion 11 may be provided with a through hole to connect the drainage channel to the outside. When the sealing assembly 13 is assembled, the drainage hole 135 can communicate with the snap-fit hole 1132 to discharge the condensate formed by the water mist entering the snap-fit hole 1132 to the rearview mirror assembly 1, thereby preventing the condensate from lingering in the snap-fit hole 1132 or penetrating into the receiving cavity and damaging the camera, thus improving the safety of the camera.
[0056] According to one embodiment of the present invention, the sealing assembly 13 further includes an extension 136 disposed on the lower side of the sealing plate 132, and the extension 136 is movably sleeved on at least a portion of the outer periphery of the support shaft 131. Figure 7As shown, during assembly, the sealing assembly 13 can have an extension 136 on the lower side of the sealing plate 132. The extension 136 can be sleeved on the support shaft 131, and the extension 136 and the support shaft 131 can move relative to each other. The elastic element 134 is sleeved on the outer periphery of the extension 136 and the support shaft 131. When the sealing assembly 13 is assembled, the elastic element 134 is in a compressed state and can apply a thrust to the sealing plate 132. When the second locking part 121 engages with the first locking part 113, the free end of the second locking part 121 can push the sealing plate 132, causing the extension 136 to move downward relative to the support shaft 131. When the second locking part 121 disengages from the first locking part 113, the elastic element 134 can drive the sealing plate 132 to reset. At this time, the extension 136 moves upward relative to the mounting shaft. The extension 136 can improve the stability of the connection between the sealing plate 132 and the support shaft 131, and at the same time improve the sealing effect of the sealing assembly 13 itself.
[0057] The vehicle according to the present invention is briefly described below.
[0058] The vehicle according to the present invention includes the rearview mirror assembly 1 in the above embodiments. Since the vehicle according to the present invention is equipped with the rearview mirror assembly 1 in the above embodiments, after the rearview mirror assembly 1 is assembled with the vehicle, the vehicle can choose whether to assemble the rearview mirror body 12 according to the actual environmental conditions. For example, in good weather, it is not necessary to assemble the rearview mirror body 12. The rearview function is realized by collecting the information of the rear view of the vehicle body through the camera on the base part 11. Moreover, the rearview mirror body 12 not being assembled can reduce the wind resistance and wind noise of the vehicle body and improve the driving experience. In extreme weather, the rearview mirror body 12 can be assembled with the base part 11. The rearview function is realized by collecting the information of the rear view of the vehicle body through the optical mirror 123. The influence of impurities such as water mist and mud on the process of collecting the view information can be reduced, and the clarity when looking behind can be improved. In addition, the rearview mirror assembly 1 has a simple overall structure and the operation of changing the rearview mode is convenient, which can improve the user experience of the vehicle.
