Description

Technical Field

[0001] This application relates to the field of automotive technology, and more specifically, to an interior rearview mirror and an automobile. Background Technology

[0002] With societal development, automobiles have become an indispensable means of transportation for people's work and daily lives. During driving, to allow drivers to easily observe the situation in the back seat and expand their field of vision, it is particularly important to increase the illumination range of the rearview mirror, especially when the driver is traveling alone with a child. When the child is sitting in the back seat, it is difficult for the driver to observe the child's movements. Frequently looking back poses a driving safety hazard. When observing through the rearview mirror, due to the relative positions of the driver and child and the relatively small reflective surface of existing rearview mirrors, blind spots exist, making it difficult to observe the child's movements.

[0058] To make the purpose, technical solution, and advantages of this application clearer, the following will be described in conjunction with the appendix. Figure 1-6 This application will be described in further detail. It is obvious that the described embodiments are merely some, not all, of the embodiments described herein. All other embodiments obtained by those skilled in the art based on the embodiments described herein without inventive effort are within the scope of protection of this application.

[0059] It should be understood that although the terms first, second, third, etc., may be used in the embodiments of this application, these descriptions should not be limited to these terms. These terms are only used to distinguish the descriptions. For example, first may also be referred to as second without departing from the scope of the embodiments of this application, and similarly, second may also be referred to as first.

[0060] An interior rearview mirror includes a rearview mirror housing 1, a main lens 4, a parent-child mirror 7, a lifting structure 5, and a rotating structure 6.

[0061] The rearview mirror housing 1 is movably mounted on the rearview mirror mounting base 2, which is fixed to the front of the vehicle interior. A parent-child mirror 7 is slidably mounted inside the rearview mirror housing 1. The rearview mirror of this application controls the raising and lowering of the parent-child mirror 7 through the lifting structure 5 and controls the rotation angle of the parent-child mirror 7 through the rotating structure 6, thereby controlling the reflection angle of the parent-child mirror 7.

[0062] This invention improves the overall reflection range of the rearview mirror by incorporating a parent-child mirror 7. Simultaneously, the lifting structure 5 and rotating structure 6 control the lifting and rotation angle of the parent-child mirror 7, facilitating the driver's observation of the rear seats. Furthermore, an eye recognition sensor installed on the rearview mirror collects the driver's eye information, and based on this information, the lifting mechanism and rotating structure 6 control the lifting and rotation angle of the parent-child mirror 7, enhancing the driver's observation and improving safe driving behavior.

[0063] The following description, in conjunction with the accompanying drawings, will provide a detailed account of this embodiment.

[0064] like Figure 1 , Figure 4 , Figure 5 and Figure 6 An interior rearview mirror, as shown, includes:

[0065] A rearview mirror housing 1 is movably mounted on a rearview mirror mounting base 2. Specifically, the rearview mirror housing 1 is movably connected to the rearview mirror mounting base 2 via an angle adjustment structure 3. The angle adjustment structure 3 includes: an angle adjustment block 31 bolted to the rear end of the rearview mirror housing 1; a fixed ball joint 32 integrally connected to the angle adjustment block 31 and located at the rear end of the angle adjustment block 31; and a ball joint connecting pin 33 fixedly mounted on the rearview mirror mounting base 2 and movably connected to the fixed ball joint 32. Since the fixed ball joint 32 and the ball joint connecting pin 33 are movably connected, the illumination angle of the rearview mirror housing 1 can be freely adjusted manually during use.

[0066] Combination Figure 2As shown; the front opening of the rearview mirror housing 1 is provided with a main lens 4; in order to expand the illumination range of the interior rearview mirror, a parent-child mirror 7 is slidably arranged inside the rearview mirror housing 1; specifically: a strip-shaped hole 11 is opened on the top right side of the rearview mirror housing 1, and the parent-child mirror 7 can move up and down at the strip-shaped hole 11 under the drive of the lifting structure 5; the advantage of this design is that, since the lifting position of the parent-child mirror 7 is set on the top right side of the rearview mirror housing 1, it can greatly improve the driver's field of vision, especially when the driver is traveling alone with a child, the driver can observe the child sitting in the back seat through the parent-child mirror 7, avoiding blind spots in the driver's field of vision, which would prevent the driver from being unable to observe the child. At the same time, it also avoids the safety hazard of the driver frequently looking back during driving.

[0067] When the parent-child mirror 7 extends out of the strip hole 11 under the drive of the lifting structure 5, the rotation angle of the parent-child mirror 7 is adjusted by the rotating structure 6, thereby adjusting the reflection angle of the parent-child mirror 7.

[0068] Furthermore, the lifting structure 5 includes a retainer 51, a drive motor 52, a rack 53, and a support limiting member 55; wherein, the retainer 51 is fixed inside the rearview mirror housing 1 by bolts, and a parent-child mirror 7 is slidably disposed inside the retainer 51; the drive motor 52 is fixed on the retainer 51, and the output shaft of the drive motor 52 is driven and connected to the rack 53 through a transmission member 54, for driving the rack 53 to move up and down, and synchronously driving the parent-child mirror 7 to move up and down; specifically: the front end of the rack 53 is movably connected to the parent-child mirror 7 through a rotating structure 6; the right side of the rack 53 is slidably engaged with the support limiting member 55 and slides on the retainer 51; the left side of the rack 53 is engaged with the transmission member 54, and the transmission member 54 drives the rack 53 to move up and down. The advantage of this design is that when the rack 53 drives the parent-child mirror 7 to fully extend out of the strip hole 11, the lower part of the rack 53 is kept fixed by the cooperation of the support limiting member 55 and the transmission member 54, thereby preventing the rack 53 from disengaging from the transmission member 54.

[0069] Optionally, the transmission component 54 is a drive gear, which is sleeved on the output shaft; the support and limiting component 55 is a U-shaped guide rail, which is fixed on the retainer 51 and slides with the rack 53 to prevent the rack 53 from disengaging from the drive gear.

[0070] like Figure 3As shown, the rotating structure 6 includes a protective shell 61, a first drive motor 62, a second drive motor 63, a first transmission component 64, and a second transmission component 65. Specifically, the protective shell 61 is fixedly connected to the rack 53. The protective shell 61 houses the first drive motor 62 and the second drive motor 63 for driving the parent-child mirror 7 to rotate. One end of the first transmission component 64 is driven by the first drive motor 62, and the other end is movably connected to the parent-child mirror 7. The second transmission component 65 has the same structure as the first transmission component 64. One end of the second transmission component 65 is driven by the second drive motor 63, and the other end is movably connected to the parent-child mirror 7. Further, the first transmission component 64 is located at the upper or lower part of the protective shell 61 to drive the parent-child mirror 7 to rotate back and forth; the second transmission component 65 is located on the left or right side of the protective shell 61 to drive the parent-child mirror 7 to rotate left and right.

[0071] In this embodiment, the first transmission component 64 is disposed on the upper part of the protective shell 61; the second transmission component 65 is disposed on the left side of the protective shell 61.

[0072] Optionally, the first transmission component 64 includes: a first turbine 640 meshing with the output shaft of the first drive motor 62, a first transmission rod 641 fixedly connected to the first turbine 640, and a first adjusting rod 642 fixedly connected to the first transmission rod 641; the free end of the first adjusting rod 642 is machined into a first ball head pin, which is movably connected to the ball head seat at the rear end of the parent-child mirror 7.

[0073] Accordingly, the second transmission component 65 includes: a second turbine 650 meshing with the output shaft of the second drive motor 63, a second transmission rod 651 fixedly connected to the second turbine 650, and a second adjusting rod 652 fixedly connected to the second transmission rod 651; the free end of the second adjusting rod 652 is machined into a second ball head pin, which is movably connected to the ball head seat at the rear end of the parent-child mirror 7 through the second ball head pin.

[0074] In another embodiment of this application, the first transmission component 64 may further include a first-stage worm gear; the difference from the above embodiment is that the output shaft of the first drive motor 62 is connected to the first turbine 640 through the first-stage worm gear.

[0075] Furthermore, the rearview mirror of this application also includes a human eye recognition sensor; the human eye recognition sensor is installed on the rearview mirror and electrically connected to the vehicle controller for collecting human eye information; the vehicle controller controls the lifting structure 5 and the rotating structure 6 to start according to the human eye information collected by the human eye recognition sensor, thereby adjusting the reflection angle of the parent-child mirror 7.

[0076] It should be noted that the human eye recognition sensor can be a miniature camera or an image acquisition device. By being installed in front of the vehicle interior, it is convenient to collect the driver's eye information and is not limited to the rearview mirror. In use, the human eye recognition sensor on the lens collects the driver's line of sight and position information. The vehicle controller controls the height and rotation angle of the seven lenses of the parent-child mirror based on the collected human eye information, which facilitates the driver's observation and improves the driver's safe driving behavior.

[0077] This embodiment also provides a car using the above-described embodiments, the car including the aforementioned interior rearview mirror.

However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.
