[0062] Example

[0063] like Figures 1 to 8 A specific implementation of the installation structure of a gimbal camera module is shown, which is used for outdoor shooting of a car, including: a gimbal camera, including a shell and a camera module 1, the camera module 1 is arranged on the shell, and the gimbal camera is arranged at a roof beam 2 on the windshield; wherein, the camera module 1 can adopt a 4800W camera module 1.

[0064] The camera module 1 is suitable for shooting outside the vehicle, and the shooting depression angle of the camera module 1 is in the range of 10° to 20°. Figure 1 As shown. Among them, the shooting depression angle of the camera module 1 is the angle between the lower edge of the shooting angle of the camera module 1 and the horizontal line, and the depression angle is generally lower than the horizontal line. The shooting elevation angle is the difference between the shooting elevation angle and the shooting depression angle. The shooting elevation angle is the angle between the upper edge of the shooting angle of the camera module 1 and the horizontal line, and the depression angle is generally higher than the horizontal line.

[0065] Furthermore, the shooting pitch angle of the camera module 1 is in the range of 60° to 75°, which makes the blank space of the sky in the captured videos and pictures more beautiful.

[0066] like Figure 1 and Figure 2 As shown, taking the vehicle body as an example, the vehicle body can be within the range of 1.905m in height, that is, the height of the camera module 1 is within the range of 1.905m in height, the height of the hood can be within the range of 1.549m, and the horizontal distance between the camera module 1 and the front end of the vehicle body can be within the range of 2.044m, so that the shooting depression angle of the camera module 1 passes through the vehicle body, such as the hood part.

[0067] The shooting pitch angle of the camera module 1 is within the range of 10° to 20°, which can ensure that the vehicle body part in the captured video and picture will not be too much and affect the quality and beauty of the video and picture. The shooting pitch angle of the camera module 1 is 60° to 75°, which can ensure that there is enough white space in the sky part, thereby increasing the quality and beauty of the video and picture.

[0068] Optionally, the shooting depression angle of this embodiment can be selected to be 13°, 15° or 18°.

[0069] Furthermore, the shooting pitch angle of the camera module 1 is in the range of 16° to 17°, and in this embodiment, it can be selected as 16.275°. The vehicle body can be located in the captured video and picture, and the camera module 1 has the function of a driving recorder. The shooting pitch angle of the camera module 1 is in the range of 67° to 69°, and in this embodiment, it can be selected as 68.519°.

[0070] Further, such as Figure 2As shown, the distance of the lower boundary line of the shooting field of view of the camera module 1 is within the range of 1.6 to 2.3m. The lower edge of the shooting field of view of the camera module 1 can capture the vehicle body. Among them, the shooting field of view boundary line is the boundary of the shooting angle of view of the camera module 1, and its distance is the intersection line of the boundary line with the ground, and the horizontal distance between this intersection line and the camera module 1. The shooting field of view lower boundary line is the intersection line of the lower edge of the shooting angle of view of the camera module 1 and the ground, and its distance is the intersection line of the lower edge of the shooting angle of view of the camera module 1 and the ground, and the horizontal distance between this intersection line and the camera module 1. It should be noted that the shooting function is actually performed by the shooting lens 9 in the camera module 1. Therefore, the depression angle, elevation angle, pitch angle and field of view boundary line can be understood as taking the shooting lens 9 as the base point.

[0071] Further, such as Figure 2 As shown, the lower boundary line distance of the shooting field of view of the camera module 1 is within the range of 1.9 to 2.0 m. In this embodiment, it can be selected to be within the range of 1.95 m. The lower edge of the shooting angle of the camera module 1 passes through the vehicle body, such as the hood on the vehicle body, and the vehicle body is located in the captured video and picture, so that the pan-tilt camera has the function of a driving recorder.

[0072] Further, such as Figure 2 As shown, the 15% shooting field of view boundary line distance of the camera module 1 is within the range of 2.5 to 3.2m. It can be understood that the shooting angle of the camera module 1 is tangent to the surface of the vehicle body. The camera module 1 is no longer blocked by the front of the vehicle, and the obtained video and picture no longer contain the front part of the vehicle. When the horizontal distance between a person and the camera module 1 exceeds the 15% shooting field of view boundary line distance, the camera module 1 can capture the complete human body video and picture.

[0073] Further, such as Figure 2 As shown, the 15% shooting field of view boundary line distance of the camera module 1 is within the range of 2.8 to 2.9m. In this embodiment, it can be selected to be within the range of 2.814m. When the shooting angle of the camera module 1 exceeds the 15% shooting field of view boundary line distance, the camera module 1 is no longer blocked by the front of the vehicle, and the obtained video and picture no longer contain the front part of the vehicle.

[0074] Further, such as Figure 2 As shown, the follow-up shooting field of view boundary line distance of the camera module 1 is within the range of 3.5 to 4.5m. When the shooting angle of the camera module 1 exceeds the shooting field of view boundary line, the camera module 1 of the pan-tilt camera can follow the shooting. It should be noted that the pan-tilt camera has certain viewing angle requirements when performing follow-up shooting. Only when the position of the object exceeds the distance of the follow-up shooting field of view boundary line, the camera module 1 of the pan-tilt camera can follow the shooting.

[0075] Further, such as Figure 2As shown, the follow-up shooting field of view boundary line distance of the camera module 1 is within the range of 4.0 to 4.1 m. In this embodiment, it can be selected to be within the range of 4.0 to 33 m. When the shooting angle of the camera module 1 exceeds the shooting field of view boundary line, the camera module 1 of the pan-tilt camera can follow and take pictures.

[0076] Further, such as Figure 8 As shown, a decorative panel 3 is provided on the roof cross beam 2, and the roof cross beam 2 and the decorative panel 3 form a mounting cavity, the gimbal camera is arranged in the mounting cavity, and the camera module 1 is located outside the mounting cavity.

[0077] Further, such as Figures 3 to 5 As shown, the housing further includes: the upper cover includes a top surface 4 and an annular circumferential surface 5 from top to bottom, wherein the annular circumferential surface 5 and the top surface 4 enclose a storage space, the storage space is suitable for accommodating the camera module 1, the annular circumferential surface 5 includes a first arc segment 6 and a second arc segment 7 distributed along the circumferential direction, the first arc segment 6 is provided with a mounting hole 8, the mounting hole 8 is suitable for accommodating the shooting lens 9 of the camera module 1, the first arc segment 6 where the mounting hole 8 is located has a first busbar 10, the second arc segment 7 has a second busbar 12, and the absolute value of the slope of the first busbar 10 is less than the absolute value of the slope of the second busbar 12. The slopes of the first busbar 10 and the second busbar 12 are both slopes with respect to the vertical line. It should be noted that a decorative shell can also be provided on the annular circumferential surface 5, and a through hole is provided at the top end of the decorative shell so that the top surface 4 is connected to the outside, and a gap can be provided between the decorative shell and the annular circumferential surface 5. A certain gap may also be provided between the upper cover and the decorative plate 3 so that the camera module 1 will not interfere with the decorative plate 3 when rotating along with the upper cover.

[0078] Further, such as Figure 5 As shown, the absolute value of the slope of the first busbar 10 is in the range of In the range of, the absolute value of the slope of the second busbar 12 is in the range of 0.7 to 1.19. It should be noted that if the first acute angle 21 formed by the first busbar 10 and the vertical line 11 is too small, after the upper shell is installed, the installation direction of the camera module 1 is slightly downward, that is, the camera module 1 will capture the image in front of the vehicle body. If the first acute angle 21 is too small, it means that the slope of the first busbar 10 of the first curved surface where the mounting hole 8 is located will be smaller, and the shooting lens 9 of the camera module 1 is fixed to the mounting hole 8, which will cause the lower field of view of the camera to capture the front cover of the vehicle body, affecting the camera's shooting field of view. , and if the first acute angle 21 is too small, the overall wind resistance of the upper shell will increase; if the first acute angle 21 formed by the first busbar 10 and the vertical line 11 is too large, since the lower field of view of the camera module 1 will capture the image in front of the vehicle, if the first acute angle 21 is too large, it means that the slope of the first busbar 10 of the first curved surface where the mounting hole 8 is located will be larger, and the shooting lens 9601 of the camera module 1 is fixed to the position of the mounting hole 8, which will cause the lower field of view of the camera module 1 to capture images away from the vehicle body, affecting the shooting angle of the camera module 1. If the second acute angle 22 formed by the second busbar 12 and the vertical line 11 is too small, the second arc segment 7 will be similar in shape to the first arc segment 6, resulting in increased wind resistance of the upper cover and whistling. If the second acute angle 22 formed by the second busbar 12 and the vertical line 11 is too large, the busbar slope of the second arc segment 7 of the upper cover will be too large, which will affect the aesthetics of the entire upper cover on the one hand, and on the other hand, the space left for the camera module 1 will become smaller while the position of the connecting portion 13 remains unchanged, making it impossible to accommodate the camera module 1.

[0079] By setting different arc segments, the upper cover has a special shape, and the absolute value of the slope of the first busbar 10 is smaller than the absolute value of the slope of the second busbar 12, so that the lower viewing angle of the camera module 1 in the mounting hole 8 can more easily capture the image in front of the car, and the lower viewing angle of the camera module 1 is easier to capture the image in front of the car. The second arc segment 7 facing away from the mounting hole 8 has a second busbar 12, and the absolute value of the slope of the first busbar 10 is smaller than the absolute value of the slope of the second busbar 12, which can better reduce wind resistance and save production materials. Through the above settings, it can be ensured that the camera module 1 in the upper cover can more easily capture the image in front of the car and reduce wind resistance.

[0080] Further, such as Figure 3 and Figure 4 As shown, the upper cover also includes: a connecting portion 13 and a fixing portion 14, which are arranged in the installation cavity, the connecting portion 13 is connected and arranged between the annular circumferential surface 5 and the fixing portion 14, the connecting portion 13 and the fixing portion 14 are both rotating bodies, the outer diameter of the fixing portion 14 is larger than the outer diameter of the connecting portion 13, and the fixing portion 14, the connecting portion 13, the top surface 4 and the annular circumferential surface 5 are integrally formed.

[0081] Furthermore, the rotation axis of the fixing portion 14 coincides with the rotation axis of the connecting portion 13 and is offset from the geometric center of the top surface 4, so that the camera module 1 can rotate during shooting.
