[0054] Figure 1 FIG. is a schematic structural diagram of a schematic embodiment of a camera device for a vehicle rearview mirror. Refer to Figure 1 , in the schematic embodiment, the camera device 100 includes a housing 10, a sleeve 20, and a camera assembly 30. The sleeve 20 is disposed in the housing 10 and is capable of moving relative to the housing 10 along a first direction D1 and its opposite direction. The camera assembly 30 includes a rotating shaft 31 and a camera 32. The rotating shaft 31 passes through the sleeve 20 and is capable of rotating relative to the sleeve 20 about a first axis L1. The first axis L1 is parallel to the first direction D1. One end of the rotating shaft 31 is located outside the housing 10, and the structures of the sleeve 20 and the rotating shaft 31 are arranged so that their relative positions along the first direction D1 are fixed. The camera 32 is fixedly provided at one end of the rotating shaft 31 located outside the housing 10.
[0055] Through the cooperation of the rotating shaft and the sleeve, the camera can move along the first direction and its opposite direction, and can rotate about the first axis to obtain a 360° shooting angle of view, effectively reducing the monitoring blind area of the vehicle. In addition, the relative positions of the sleeve and the rotating shaft along the first direction are fixed, which also ensures the overall stability of the camera assembly during adjustment, ensuring the clarity and stability of the captured image.
[0056] Figure 2 For the purpose of illustration Figure 1 is a partial cross-sectional view of the camera device shown in Figure 2 is a partial cross-sectional view taken along Figure 1 II-II only showing the housing 10 and the sleeve 20. Refer to Figure 1 and Figure 2 , in the schematic embodiment, the camera device 100 further includes a first gear 40 and a first driving mechanism 50 disposed in the housing 10. The first gear 40 is capable of rotating relative to the housing 10 about a second axis L2. The second axis L2 is perpendicular to the first direction D1. The sleeve 20 is provided with a rack 22 extending along the first direction D1. The first gear 40 meshes with the rack 22. The output shaft of the first driving mechanism 50 is connected to the first gear 40 to drive the first gear 40 to rotate about the second axis L2. By rotating the first gear 40, the sleeve 20 and the camera assembly 30 can be driven to move along the first direction D1 and its opposite direction. The first driving mechanism 50 is, for example, a stepper motor. This facilitates precise adjustment of the position of the camera along the first direction. However, it is not limited thereto, and the first driving mechanism 50 can also be other forms of driving mechanisms such as a servo motor. It is also possible not to provide the first driving mechanism 50 and instead manually rotate the first gear 40.
[0057] Refer to Figure 2 , in the schematic embodiment, the imaging device 100 further includes a third gear 60 and a second driving mechanism 70 disposed within the housing 10, and a driving gear 71 and a driven gear 72 that mesh with each other. The output shaft of the second driving mechanism 70 is connected to the driving gear 71. The third gear 60 is fixedly connected to the driven gear 72 coaxially. When the second driving mechanism 70 drives the driving gear 71 to rotate, the driving gear 71 can drive the driven gear 72 to rotate, thereby driving the third gear 60 to rotate about a third axis L3 parallel to the first direction D1. The imaging assembly 30 further includes a second gear 33. The second gear 33 is fixedly disposed at one end of the rotating shaft 31 located inside the housing 10. The third gear 60 meshes with the second gear 33 to drive the rotating shaft 31 and the camera 32 to rotate about the first axis L1 under the drive of the second driving mechanism 70. The second driving mechanism 70 is, for example, a stepper motor. This facilitates accurately and stably adjusting the rotation angle of the camera in a plane perpendicular to the first direction. However, it is not limited thereto. In other schematic embodiments, the manner in which the driving gear 71 and the driven gear 72 that mesh with each other are used to transmit force and torque between the second driving mechanism 70 and the third gear 60 can be flexibly replaced with other forms of force and torque transmission structures. The second driving mechanism 70 can also be replaced with other forms of driving mechanisms such as a servo motor according to the actual application scenario. Of course, for the sake of streamlining the mechanical structure, the second driving mechanism 70 can also be not provided, and the third gear 60 can be rotated manually instead.
[0058] In the schematic embodiment, the first driving mechanism 50 and the second driving mechanism 70 are respectively connected to the central control screen through electric wires ( Figure 1 and Figure 2 not shown in the figure), and the camera 32 is connected to the central control screen through a network cable. The driver can manually control the forward or reverse rotation of the first driving mechanism 50 and the second driving mechanism 70 according to the picture information transmitted by the camera 32 displayed on the central control screen to adjust the position of the camera 32 along the first direction D1 and the rotation angle in a plane perpendicular to the first direction D1.
[0059] Figure 3 For the partial structure sectional view of III-III along Figure 2 in the figure. To ensure the clarity of the drawing, Figure 3 only the partial structure of the housing 10 and the sectional view of the sleeve 20 are shown. Refer to Figure 2 and Figure 3, in a schematic embodiment, the sleeve 20 is disposed within the housing 10. An annular groove 311 extending circumferentially along the rotary shaft 31 is formed on the outer circumferential surface of the rotary shaft 31. The sleeve 20 is sleeved on the rotary shaft 31 in the opposite direction of the first direction D1 and is embedded in the annular groove 311. The second gear 33 is detachably disposed at the front end of the rotary shaft 31 along the first direction D1 to prevent the sleeve 20 from disengaging from the rotary shaft 31 along the first direction D1, thereby fixing the relative positions of the sleeve 20 and the rotary shaft 31 along the first direction D1. The structure of the above-mentioned sleeve and rotary shaft is simple, compact and has stable cooperation.
[0060] However, not limited thereto, in another schematic embodiment, the sleeve 20 and the rotary shaft 31 may also adopt other cooperation methods to fix their relative positions along the first direction D1. Refer to Figure 4 , Figure 4 FIG. is a schematic diagram of another schematic embodiment for illustrating the cooperation relationship between the sleeve and the rotary shaft. Figure 4 FIG. is a schematic diagram of a part of the housing 10 and the sleeve 20 provided with the groove 21 cut along a direction perpendicular to the first direction D1. The sleeve 20 is disposed within the housing 10. An annular groove 21 is formed circumferentially on the inner wall of the sleeve 20. A spring plunger 312 is mounted on the outer wall of the rotary shaft 31 (for clarity of the drawing, the rotary shaft 31 and the spring plunger 312 are not cut). The spring plunger 312 is mounted on the rotary shaft 31 by a method well known to those skilled in the art. Figure 4 Only one spring plunger 312 is shown in FIG., and the actual number of spring plungers 312 can be adjusted according to the application scenario. The spring plunger 312 can be inserted into the groove 21 to fix the relative positions of the sleeve 20 and the rotary shaft 31 along the first direction D1. At the same time, the spring plunger 312 can also slide within the groove 21 to allow the rotary shaft 31 to rotate relative to the sleeve 20 about the first axis L1. This structure is simple and convenient for disassembly and assembly.
[0061] Refer to Figure 2 and Figure 3 , in a schematic embodiment, the housing 10 has a bracket 11. The bracket 11 is disposed on the radially outer side of the sleeve 20. A guide groove 111 parallel to the first direction D1 is formed on the surface of the bracket 11 facing the sleeve 20. A guide rail 23 parallel to the first direction D1 protrudes from the surface of the sleeve 20 facing the bracket 11. The guide rail 23 is slidably inserted into the guide groove 111 to support the movement of the sleeve 20 relative to the housing 10 along the first direction D1 and its opposite direction. The guide rail and the guide groove constitute a slide rail pair structure, which is simple, easy to install and maintain, and can provide stable guidance and support for the movement of the sleeve along the first direction and its opposite direction, which is beneficial to improving the movement stability of the camera assembly.
[0062] Figure 5 It includes Figure 1Schematic structural diagram of a vehicle rearview mirror of the camera device shown. The camera device can monitor the surrounding conditions of the vehicle in all directions, improving driving safety and convenience. Refer to Figure 5 , in the illustrative embodiment, the vehicle rearview mirror 90 has a main body 91. The camera device 100 is disposed in a cavity formed by the main body 91. An opening is provided on the surface of the main body 91 facing the ground ( Figure 5 not shown in the figure), and the camera device 100 can extend the camera 32 out of the main body 91 through the opening. This prevents rainwater from entering the main body and damaging the camera device.
[0063] In practical applications, before the vehicle is powered off, the driver can operate the central control screen in advance to retract the camera. In case of ice and snow weather when the rearview mirror is frozen, the driver can operate the central control screen to adjust the position of the camera in the first direction and the rotation angle in a plane perpendicular to the first direction to assist in observing the vehicles behind and on the side. The image captured by the camera can be displayed on the central control screen in real time. In case of vehicle alarm, the driver can use the mobile phone APP to remotely control the camera to monitor the surrounding conditions of the vehicle in real time, and can also cooperate with the monitoring devices installed in the surrounding environment to avoid monitoring blind spots.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
