[0038] In this embodiment, the Z direction refers to the height direction of the vehicle, the X direction refers to the forward direction of the vehicle, and the Y direction refers to the left and right direction of the vehicle.

[0039] The first embodiment of the utility model provides a vehicle-mounted camera structure, which is installed on the roof of the vehicle. Figure 1 and Figure 2 As shown, the vehicle-mounted camera structure includes a camera module 1, a lifting mechanism 2, a rotating mechanism 3, a fixed plate 4 and a sliding plate 5, the camera module 1 is arranged outside the vehicle, the lifting mechanism 2, the rotating mechanism 3, the fixed plate 4 and the sliding plate 5 are arranged inside the vehicle, a first installation space is defined between the roof and the fixed plate 4, the lifting mechanism 2 is installed on the fixed plate 4 and is located in the first installation space, the sliding plate 5 is connected to the lifting mechanism 2, a second installation space is defined between the sliding plate 5 and the roof, the rotating mechanism 3 is installed on the sliding plate 5 and is located in the second installation space, and a rotating shaft 32 of the rotating mechanism 3 extends out of the roof and is connected to the camera module 1.

[0040] The camera module 1 is arranged outside the roof of the vehicle to obtain image information outside the vehicle; the lifting mechanism 2, the rotating mechanism 3, the fixed plate 4 and the sliding plate 5 are arranged inside the vehicle, and the lifting mechanism 2 is arranged in the first installation space inside the vehicle, and the rotating mechanism 3 is arranged in the second installation space inside the vehicle. The lifting mechanism 2 is used to adjust the height direction of the camera module 1, and the rotating structure is used to adjust the left and right direction of the camera module 1 in the horizontal direction. The fixed plate 4 is used to support the lifting mechanism 2, and then plays a role in supporting the vehicle-mounted camera structure, and the sliding plate 5 is used to support the rotating mechanism 3. The vehicle-mounted camera structure is provided with a lifting mechanism 2 and a rotating mechanism 3, which can not only adjust the camera height, but also adjust the camera angle to expand the camera range. The surrounding scenery can be photographed during driving, without the need for passengers to reach out from the window to shoot, which increases safety and convenience. When the vehicle is parked, the environment in a large range around can be monitored. For example, the perpetrator can be found when the vehicle is scratched; if placed in the courtyard, it can also serve as a temporary monitoring device.

[0041] like Figure 2 and Figure 3 As shown, the lifting mechanism 2 includes a lifting drive motor 21, a screw rod 22 and a screw nut 23. The lifting drive motor 21 is installed on the fixing plate 4. One end of the screw rod 22 is connected to the lifting drive motor 21. The screw nut 23 is connected to the screw rod 22 by a thread. The sliding plate 5 is installed on the screw rod 22 and connected to the screw nut 23. When the lifting drive motor 21 is started, the screw rod 22 can be driven to rotate. The screw nut 23 threadedly connected to the screw rod 22 drives the sliding plate 5 to move up and down along the screw rod 22, thereby enabling the camera module 1 to move up and down, thereby expanding the shooting range of the camera module 1.

[0042] In some embodiments, the vehicle-mounted camera structure further includes a slide bar 6 disposed in the first installation space, the slide bar 6 is mounted on the fixed plate 4, the sliding plate 5 is mounted on the slide bar 6, and can move along the slide bar 6. The slide bar 6 is disposed in the first installation space, specifically, disposed between the fixed plate 4 and the sliding plate 5, and the two ends extend out of the fixed plate 4 and the sliding plate 5, respectively. The slide bar 6 plays a guiding role in the movement of the sliding plate 5, thereby improving the stability of the sliding plate 5 during the movement. A guide sleeve 61 is installed at the connection between the slide bar 6 and the sliding plate 5, and the guide sleeve 61 is movably sleeved outside the slide bar 6 so that the slide bar 6 can move along the guide sleeve 61, and the stability of the operation is further ensured during the movement of the slide bar 6.

[0043] In this embodiment, there are two slide bars 6, which are arranged at intervals on both sides of the fixed plate 4, and the two slide bars 6 and the screw rod 22 form a triangular structure. The slide bars 6 are arranged on both sides of the fixed plate 4 to improve the stable guiding effect of the slide bars 6. The slide bars 6 cooperate with the two screw rods 22 to form a triangular structure, which ensures the structural stability of the lifting mechanism 2 and ensures that the camera module 1 with the sliding plate 5 installed is lifted and lowered smoothly along the slide bars 6.

[0044] In some embodiments, the lifting mechanism 2 further includes a screw bolt 24, one side of the sliding plate 5 is connected to the screw nut 23, and the other side of the sliding plate 5 is connected to the screw bolt 24, and the screw bolt 24 cooperates with the screw nut 23 to fix or loosen the sliding plate 5. The screw nut 23 and the screw bolt 24 are respectively arranged on both sides of the sliding plate 5, and the screw nut 23 and the screw bolt 24 are connected by threads, which can clamp the sliding plate 5 and improve the installation reliability of the sliding plate 5. The screw nut 23 and the screw bolt 24 are threadedly connected, which can quickly fix or loosen the sliding plate 5 and improve the efficiency of installing and removing the sliding plate 5.

[0045] The rotating mechanism 3 includes a rotating drive motor 31 and a rotating shaft 32. The rotating drive motor 31 is mounted on the sliding plate 5. One end of the rotating shaft 32 is connected to the power end of the rotating drive motor 31, and the other end of the rotating shaft 32 extends out of the roof and is connected to the camera module 1. After the rotating drive motor 31 is started, the rotating shaft 32 is driven to rotate, and then the camera module 1 is driven to rotate, so that the camera module 1 can swing left and right, thereby expanding the camera range of the camera module 1.

[0046] The rotating shaft 32 extending out of the roof is sleeved with a limiter 33, which is arranged at the connection between the rotating shaft 32 and the roof. For example, the limiter 33 is a rubber sleeve, which is arranged at the connection between the rotating shaft 32 and the roof, restricting the rotating shaft 32 to move only in the Z direction and playing a waterproof role.

[0047] The vehicle-mounted camera structure is installed on the roof cross beam 7. The roof cross beam 7 is welded to the vehicle body 100. A through hole is provided on the roof cross beam 7 for the rotation shaft 32 to pass through. The stopper 33 is provided at the connection between the rotation shaft 32 and the roof cross beam 7. The vehicle-mounted camera structure is installed on the roof cross beam 7 so that the vehicle-mounted camera structure has a higher height and its camera field of view can be ensured. The roof cross beam 7 can be a structural member of the vehicle body 100 itself, directly using the components of the vehicle itself, and making full use of the roof space; the roof cross beam 7 can also be an additional member of the vehicle body, which provides an installation position for the vehicle-mounted camera structure without affecting the strength of the vehicle body 100.

[0048] like Figure 2 As shown, the sliding plate 5 is stepped to form installation positions of different heights, and the first installation position 51 of the rotating mechanism 3 is lower than the second installation position 52 of the screw rod 22. The second installation position 52 of the screw rod 22 refers to the position where the screw rod 22 is connected to the sliding plate 5. The height of the second installation position 52 of the screw rod 22 is higher, and the height of the first installation position 51 of the rotating mechanism 3 is lower. In the limited space of the first installation space, the height of the second installation position is increased, and the screw rod 22 with a larger length specification can be installed between the roof cross beam 7 and the fixed plate, thereby improving space utilization. In the limited space of the first installation space, the camera module 1 has as large an adjustment range as possible in the height direction.

[0049] like Figure 4-Figure 6 As shown, the camera module 1 includes a housing 11, a camera bracket 12 and a camera 13. The camera bracket 12 and the camera 13 are arranged in the housing 11, and the camera 13 is installed on the camera bracket 12. The rotating shaft 32 extends from the bottom of the housing 11 into the housing 11 and is engaged with the camera bracket 12. The camera bracket 12 is used to connect with the camera 13 to support and position the camera 13. The housing 11 accommodates the camera bracket 12 and the camera 13 therein, and plays a role in dustproofing and protecting the camera 13 from bumps. One end of the rotating shaft 32 extends from the bottom of the housing 11 into the housing 11, and is engaged with the camera bracket 12 through the engaging portion 321 at the end of the rotating shaft 32, so as to realize the connection between the rotating shaft 32 and the camera module 1.

[0050] The camera bracket 12 is provided with a limiting column 14 arranged along the front-rear direction of the vehicle body 100, and the rotating shaft 32 is provided with a limiting hole that cooperates with the limiting column 14. Exemplarily, the camera 13 of the camera module 1 is arranged toward the front of the vehicle, and the limiting column 14 is arranged along the radial direction of the rotating shaft 32. The limiting column 14 passes through the rotating shaft 32 to connect the camera bracket 12 and the rotating shaft 32, thereby limiting the Y-direction movement of the rotating shaft 32.

[0051] A camera hole matching the camera 13 is provided at the front of the housing 11 to ensure the shooting field of view of the camera 13 .

[0052] In some embodiments, the rear portion of the housing 11 is provided with a limiting rib 15 extending toward the rotating shaft 32. The limiting rib 15 is formed to extend toward the rotating shaft 32 along the vehicle X-direction, and can limit the X-direction movement of the rotating shaft 32.

[0053] In other embodiments, the limiting rib 15 extends to overlap the limiting column 14 and cooperates with the limiting column 14 to limit the rotating shaft 32, thereby improving the limiting effect and preventing the rotating shaft 32 from moving in the X direction and the Y direction.

[0054] The working process of the vehicle-mounted camera structure is:

[0055] The lifting drive motor 21 is started to drive the screw rod 22 to rotate, and the screw rod nut 23 threadedly connected to the screw rod 22 drives the sliding plate 5 to move up and down, thereby realizing the up and down movement of the camera module 1;

[0056] The rotation drive motor 31 is started to drive the rotation shaft 32 to rotate, and the housing 11 engaged with one end of the rotation shaft 32 rotates along with the rotation of the rotation shaft 32 , thereby realizing the left and right swing of the camera module 1 .
