[0049] This application proposes a rearview mirror, and Figures 1 to 8 show some embodiments of this application.

[0050] Please refer to Figures 1 and 2. In some embodiments of this application, the rearview mirror 1000 includes a housing 1 and a camera module 2, at least a portion of which is located inside the housing 1; wherein at least a portion of the camera module 2 protrudes from an opening 15 on the housing 1 for capturing images.

[0051] When the rearview mirror 1000 in this embodiment is applied to a vehicle, the camera module 2 can capture the outside view of the vehicle and display it on the in-vehicle display screen in real time.

[0052] In some embodiments of this application, the rearview mirror 1000 further includes a support component 3, one end of which is connected to the housing 1. At least a portion of the camera module 2 is placed on the support component 3. The support component 3 is configured to restrict the position of the camera module 2 within the housing 1 so that the optical axis of the camera module 2 coincides with a preset optical axis. With this configuration, after the camera module 2 is installed into the housing 1, the support component 3 supports and limits the installation angle and position of the camera module 2, thereby enabling the optical axis of the camera module 2 to coincide with the preset optical axis of the rearview mirror 1000.

[0053] In the technical solution of this application, by providing a support component 3 inside the housing 1, the installation position and installation angle of the camera module 2 inside the housing 1 are fixed. That is, the camera module 2 can be accurately positioned and installed inside the housing 1 through the support component 3, so that the optical axis of the camera module 2 can coincide with the preset optical axis of the rearview mirror 1000, thereby enabling the image captured by the rearview mirror 1000 to be directly transmitted to the in-vehicle display screen for real-time display.

[0054] In some embodiments of this application, the camera module 2 includes a main body 21 and a lens unit 22, with at least a portion of the lens unit 22 disposed within the main body 21; a support component 3 is located between the main body 21 and the housing 1; in this embodiment, the lens unit 22 is used to take real-time photos of the exterior of the vehicle, the main body 21 encloses the lens unit 22 to provide protection for the lens unit 22, and the support component 3 is located between the main body 21 and the housing 1 to restrict the installation position of the main body 21 within the housing 1, thereby making the optical axis of the lens unit 22 coincide with the preset optical axis of the rearview mirror 1000.

[0055] Understandably, in order for the camera module 2 to capture images outside the vehicle, the lens unit 22 is exposed through the opening 15 of the housing 1.

[0056] Furthermore, the installation method between the support component 3 and the housing 1 is not limited; it can be integrally formed or installed separately. In some embodiments of this application, in order to facilitate the assembly of the rearview mirror 1000 and to make the installation of the camera module 2 within the housing 1 more stable, the support component 3 and the housing 1 are integrally formed.

[0057] In some embodiments of this application, the main body 21 includes a first sub-part 211 and a second sub-part 212 connected to each other. The second sub-part 212 is provided with a cavity 4 and an opening 5 communicating with the cavity 4. At least a portion of the lens unit 22 is located in the cavity 4, and the lens unit 22 is exposed from the opening 5. The cavity 4 provides installation space for the lens unit 22.

[0058] In some embodiments of this application, a cavity 4 is also provided on the first sub-part 211, thereby providing a larger installation space for the lens unit 22 within the main body 21.

[0059] In some embodiments of this application, when the camera module 2 is installed in the housing 1, at least a portion of the second sub-part 212 is located in the opening 15 of the housing 1, so that the lens unit 22 is exposed from the opening 15; a sealing ring is also provided between the hole wall of the opening 15 and the second sub-part 212, so as to prevent impurities or water from entering the housing 1 from the gap between the hole wall of the opening 15 and the second sub-part 212.

[0060] In this embodiment, at least one of the first sub-part 211 and the second sub-part 212 is provided with a support component 3 between itself and the housing 1. That is, in one embodiment of this application, a support component 3 is provided between the first sub-part 211 and the housing 1; in another embodiment of this application, a support component 3 is provided between the second sub-part 212 and the housing 1; and in yet another embodiment of this application, a support component 3 is provided between both the first sub-part 211 and the second sub-part 212 and the housing 1.

[0061] Please refer to Figures 3 and 4. In some embodiments of this application, the support component 3 includes a plurality of first support members 31. One end of the plurality of first support members 31 is connected to the housing 1, and the other end of the plurality of support members 31 is in direct contact with the second sub-part 212. In this embodiment, the first support member 31 is in direct contact with and tightly fitted to the second sub-part 212, so that the first support member 31 can support the second sub-part 212, thereby limiting the optical axis position of the camera module 2, realizing the precise positioning of the camera module 2, and making the optical axis of the camera module 2 coincide with the preset optical axis of the rearview mirror 1000.

[0062] In some embodiments of this application, the second sub-part 212 is cylindrical, and a plurality of first support members 31 are arranged circumferentially along the second sub-part 212.

[0063] Please refer to Figure 4. In some embodiments of this application, three first support members 31 are provided, and the three first support members 31 extend in the same direction to provide partial support for the second sub-part 212. At the same time, the three first support members 31 are arranged at intervals, and the line connecting the ends of the three first support members 31 near the second sub-part 212 is arc-shaped, which matches the surface shape of the second sub-part 212 to enhance the stability of the support for the second sub-part 212.

[0064] Please refer to Figures 5 and 6. In some embodiments of this application, the support component 3 includes at least one second support member 32. One end of the second support member 32 is connected to the housing 1, and the other end is in contact with the first sub-part 211. In this embodiment, the second support member 32 can support the first sub-part 211, thereby limiting the optical axis position of the camera module 2 and achieving precise positioning of the camera module 2, so that the optical axis of the camera module 2 coincides with the preset optical axis of the rearview mirror 1000.

[0065] In some embodiments of this application, the second support member 32 is disposed near the end of the first sub-part 211 that is away from the second sub-part 212; that is, the first sub-part 211 includes a first end connected to the second sub-part 212 and a second end opposite to the first end, and the second support member 32 is disposed near the second end of the first sub-part 211; with this arrangement, the support position of the second support member 32 on the second sub-part 212 is away from the middle position of the housing 1 and is disposed near the edge position of the housing 1, so that the support of the second support member 32 on the housing 1 is more stable.

[0066] In some embodiments of this application, a first support member 31 is provided between the second sub-part 212 and the housing 1, and a second support member 32 is provided between the first sub-part 211 and the housing 1, with the second support member 32 located near the end of the first sub-part 211 and away from the second sub-part 212. In this embodiment, the first sub-part 211 is described as the rear end of the main body 21, and the second sub-part 212 is described as the front end of the main body 21. That is, the first support member 31 and the second support member 32 are respectively provided at the front and rear ends of the main body 21, thereby balancing the camera module 2 in the direction from the front end to the rear end of the main body 21, making the imaging of the camera module 2 more stable.

[0067] It should be added that the opening 15, the first support 31, and the second support 32 located on the housing 1 are arranged sequentially in the extension direction of the preset optical axis of the rearview mirror 1000, so as to adjust the optical axis position of the camera module 2 so that the optical axis position of the camera module 2 coincides with the preset optical axis of the rearview mirror 1000.

[0068] Please refer to Figures 6 and 7. In some embodiments of this application, the camera module 2 includes a first fixing part 6, and the housing 1 includes a second fixing part 7. The first fixing part 6 and the second fixing part 7 are positioned opposite each other and are fixed by a first fastener. In this embodiment, the first fixing part 6 and the second fixing part 7 cooperate with each other to make the housing 1 and the camera module 2 securely fixed, ensuring that the optical axis position of the camera module 2 will not change after the optical axis of the camera module 2 is restricted by the support component 3 to coincide with the optical axis of the rearview mirror 1000.

[0069] The assembly method between the first fixing part 6, the second fixing part 7 and the first fastener is not limited; it can be screwed or riveted, etc.

[0070] In some embodiments of this application, the first fixing part 6 is provided with a through hole, and the second fixing part 7 is provided with a screw hole. The screw hole and the through hole are opposite to each other and communicate with each other. The first fastener is a screw. The screw passes through the through hole and is screwed into the screw hole to achieve relative fixation of the first fixing part 6 and the second fixing part 7, so that the camera module 2 can be fastened in the housing 1.

[0071] It is understandable that the cooperation between the first fixing part 6 and the second fixing part 7 can fix the camera module 2 in the approximate installation position on the housing. During the screw tightening process, the camera module 2 is accurately fixed in the position to be fixed inside the housing 1 through the contact between the first support member 31 and the second support member 32 and the surface of the camera module 2.

[0072] In some embodiments of this application, the housing 1 includes a housing body 11 and a cover plate 12. The housing body 11 is provided with a receiving cavity 8 for accommodating the camera module 2. The cover plate 12 is connected to the housing 1 and covers the receiving cavity 8. The cover plate 12 is configured to be installed on the vehicle body. In this embodiment, the assembly of the rearview mirror 1000 is completed by installing the camera module 2 onto the housing body 11 and then installing the cover plate 12 onto the housing body 11.

[0073] In this embodiment, at least one of the housing body 11 and the cover plate 12 is connected to the support component 3. That is, in one embodiment of this application, the housing body 11 is connected to the support component 3; in another embodiment of this application, the cover plate 12 is connected to the support component 3; and in yet another embodiment of this application, both the housing body 11 and the cover plate 12 are connected to the support component 3.

[0074] In some embodiments of this application, the support component 3 is disposed between the housing body 11 and the side of the camera module 2 away from the cover plate 12, that is, the first support 31 and the second support 32 are both disposed between the housing body 11 and the side of the camera module 2 away from the cover plate 12. In this embodiment, this arrangement is because the camera module 2 is first installed on the housing body 11. At this time, the accommodating cavity 8 is not yet covered, and the positioning and installation of the camera module 2 will not be blocked by the cover plate 12. This makes it easier for the operator or operating tool to adjust the installation position of the camera module 2 so that the camera module 2 is accurately positioned in the housing 1.

[0075] In some embodiments of this application, the second fixing part 7 is also provided inside the housing body 11; that is, by installing the camera module 2 and the housing body 11, the optical axis of the camera module 2 can be adjusted and restricted so that the optical axis of the camera module 2 coincides with the preset optical axis of the rearview mirror 1000.

[0076] In some embodiments of this application, the housing body 11 and the cover plate 12 are connected by screws, and the nut portion of the screw is located on the side of the cover plate 12 away from the housing body 11.

[0077] In some embodiments of this application, the rearview mirror 1000 further includes a sealing element 9, which is disposed on the side of the cover plate 12 away from the housing body 11 and located between the cover plate 12 and the vehicle body. Since there is a gap between the cover plate 12 and the vehicle body, the sealing element 9 is provided between the cover plate 12 and the vehicle body to seal the gap, thereby achieving a waterproof function.

[0078] Please refer to Figure 8. In some embodiments of this application, the rearview mirror 1000 also includes a wiring harness 13. One end of the wiring harness 13 is connected to the camera module 2, and the other end of the wiring harness 13 is connected to electrical components inside the vehicle body, so that the images captured by the camera module 2 can be transmitted to the in-vehicle display screen for real-time display.

[0079] In some embodiments of this application, a through hole 10 is provided through the cover plate 12, and the through hole 10 communicates with the accommodating cavity 8; one end of the wiring harness 13 is connected to the camera module 2, and the other end of the wiring harness 13 extends out of the accommodating cavity 8 through the through hole 10. The wiring harness 13 extends out of the through hole 10 and connects to electrical components inside the vehicle body, thereby enabling the images captured by the camera module 2 to be transmitted to an in-vehicle display screen for real-time display.

[0080] In some embodiments of this application, the cover plate 12 is provided with a protrusion 17 on the side opposite to the housing body 11, and the through hole 10 also penetrates the protrusion 17, so that the wire harness 13 can extend out from the housing 1. A locking protrusion 16 is provided on the periphery of the protrusion 17, and the locking protrusion 16 can be locked onto the periphery of the seal 9, thereby achieving pre-fixation between the seal 9 and the cover plate 12.

[0081] In some embodiments of this application, the screws connecting the housing body 11 and the cover plate 12 also pass through the sealing element 9, so that the housing body 11, the cover plate 12 and the sealing element 9 are securely fixed together.

[0082] In some embodiments of this application, the rearview mirror 1000 further includes at least one buffer 14, which is disposed between the housing 1 and the camera module 2. By providing the buffer 14, it is possible to prevent the rearview mirror 1000 from being damaged by stress directly impacting the camera module 2 when subjected to mechanical shock.

[0083] In one embodiment of this application, a buffer 14 is provided between the housing body 11 and the camera module 2; in another embodiment of this application, a buffer 14 is provided between the cover plate 12 and the camera module 2; in yet another embodiment of this application, buffers 14 are provided between both the housing body 11 and the cover plate 12 and the camera module 2.

[0084] In some embodiments of this application, the buffer 14 is a buffer foam.

[0085] In some embodiments of this application, both the housing body 11 and the cover plate 12 are plastic parts, and the material is a ternary polymer composed of acrylonitrile, styrene and acrylic rubber.

[0086] In some embodiments of this application, the seal 9 is a rubber component, and the material is ethylene propylene rubber.

[0087] In some embodiments of this application, the main body 21 of the camera module 2 is a die-cast part made of die-cast aluminum, and the lens unit 22 of the camera module 2 supports heating function and can work normally in cold winter regions.

[0088] In some embodiments of this application, the wiring harness 13 is tied to the vehicle body with cable ties, thereby reducing the amount of shaking of the wiring harness 13 and thus reducing stress transmission.
