[0002] In addition to photographing landscapes around the world, more and more enthusiasts like to photograph wild animals, and ecological photography has become a fashion.

[0003] Driving a car and photographing wild animals inside the car is a common practice for photographers. Because the car provides the best concealment; animals are not afraid of the car but will run away when they see people getting out of the car; it is also the best shelter, not afraid of wind, rain or shine; the car can also track animals in motion well; photographers are very safe inside the car, as many wild animals are aggressive and it is dangerous for photographers to take pictures on the ground.

[0004] Photographers often take pictures in the car. When taking pictures in the car, photographers lean the photographic equipment against the car window and pad it with some bags filled with soft materials to support the photographic equipment for shooting, or set up some support frames on the car window to support the photographic equipment.

[0005] However, when taking pictures in the car, shooting wild animals at the height of the car window is basically a top-down shooting angle, and it is impossible to achieve a flat shooting angle and a bottom-up shooting angle. The shooting angle often fails to reach the ideal state. It is also impossible to achieve stable shooting and meet the requirements of video shooting. Any movement of people in the car will cause the car to shake. With a slight shake of the picture, the video shooting fails. The space inside the car is narrow and crowded, and it is impossible to place the support frame of the photographic equipment, restricting the activities of photographers and making it very difficult to complete the shooting action.

[0006] Most of the photographic equipment on the market currently needs to be manually supported by photographers.

[0050] Currently, more and more photography enthusiasts like to photograph wild animals. When photographing wild animals in a car, it can not only prevent the animals from being frightened, help track the moving animals, but also protect the photographers from wind and rain, and at the same time avoid the photographers being attacked by the animals. Therefore, photographing wild animals in a car is a common practice for photographers. However, when photographing wild animals in a car, due to the height limit of the car window restricting the movement range of the photographing device, the photographing angle often fails to reach the ideal state.

[0051] In view of this, the present invention provides a lifting component for a vehicle-mounted photographing device, aiming to solve the problem that the movement range of the photographing device is restricted by the height of the car window. Among them, Figures 1 to 7 is a schematic structural diagram of an embodiment of the lifting component for a vehicle-mounted photographing device provided by the present invention; Figure 8 is a schematic structural diagram of an embodiment of an automobile photographing component provided by the present invention.

[0052] Please refer to Figures 1 to 4 , the lifting component 100 for a vehicle-mounted photographing device includes a mounting rod 1 and a connecting member 2. The mounting rod 1 extends in the vertical direction, and the lower end is used for inserting into the ground. The connecting member 2 is movably mounted on the mounting rod 1 in the vertical direction and is used for connecting with the photographing device.

[0053] In the technical solution of the present invention, the lower end of the mounting rod 1 is inserted into the ground so that the mounting rod 1 is fixed to the ground, preventing the mounting rod 1 from shaking under the influence of external forces, improving the stability of the mounting rod 1, which is helpful for shooting high-definition videos. At the same time, through the connecting member 2, the shooting device can move up and down along the mounting rod 1 to adjust the height of the shooting device. In this way, through the cooperation of the mounting rod 1 and the connecting member 2, the shooting device can stay at any height, which not only helps to expand the movement range of the shooting device, but also helps to obtain a suitable shooting angle, thus solving the problem that the movement range of the shooting device is limited by the car window.

[0054] Further, there are various ways for the connecting member 2 to move. The connecting member 2 can move up and down outside the mounting rod 1 or inside the mounting rod 1. Specifically, please refer to Figure 2 and Figure 3 , a lifting channel extending in the up and down direction is formed inside the mounting rod 1. A long hole 11 extending in the up and down direction is partially penetrated through the side wall of the lifting channel. In the radial direction of the lifting channel, one end of the connecting member 2 is movably mounted in the up and down direction in the long hole 11, and the other end extends outside the long hole 11 to form a mounting part for connecting with the shooting device. With such a setting, through the long hole 11, the connecting member 2 can move in the lifting channel, hiding the connecting member 2 inside the mounting rod 1, which not only helps to avoid the influence of the outside on the movement of the connecting member 2, but also helps to store the connecting member 2 for convenient carrying.

[0055] Further, please refer to Figure 3 , the mounting rod 1 further includes a guiding structure 16, which includes a sliding rail and a sliding block that cooperate with each other. The sliding rail and the sliding block are respectively arranged on the inner wall of the lifting channel and the connecting member 2. With such a setting, through the sliding rail and the sliding block, the connecting member 2 can move smoothly in the up and down direction, avoiding jitter and improving the stability of the movement of the connecting member 2.

[0056] In order to adjust the position of the connecting member 2 in the up and down direction, please refer to Figure 6 and Figure 7, the vehicle camera lifting assembly 100 includes a mounting base 3, a driving rope 4, and a rotational driving part. The mounting base 3 is provided at the upper end of the mounting rod 1. An installation cavity communicating with the lifting channel is formed in the mounting base 3. The upper end of the driving rope 4 extends into the installation cavity, and the lower end extends into the lifting channel and can move back and forth in the lifting channel in the vertical direction. The connecting member 2 is connected to the driving rope 4. The rotational driving part is rotatably installed in the installation cavity for driving the driving rope 4 to move. With such a setting, when it is necessary to adjust the position of the connecting member 2, the driving rope 4 is driven by the rotational driving part to move in the vertical direction, so that the connecting member 2 moves up and down. When the rotational driving part stops, the driving rope 4 stops moving and is fixed at the current position. Thus, through the rotational driving part and the driving rope 4, the connecting member 2 can stay at any position in the lifting channel, facilitating the shooting by the shooting personnel.

[0057] Further, there are various driving methods for the rotational driving part, which can be manual driving or electric driving. The present invention does not limit this. Specifically, in one embodiment, the vehicle camera lifting assembly 100 includes a rotating handle. The rotational driving part includes the part of the rotating shaft of the rotating handle inserted into the installation cavity. With such a setting, the rotational driving part is driven by the rotating handle to move the driving rope 4 in the vertical direction, thereby driving the connecting member 2 to move in the vertical direction.

[0058] In another embodiment, please refer to Figure 7 , the vehicle camera lifting assembly 100 includes a driving motor 9 and a speed reducer drivingly connected to the driving motor 9. The speed reducer has an output shaft. The rotational driving part includes the part of the output shaft inserted into the installation cavity. With such a setting, the rotational driving part is driven to rotate by the driving motor 9, so as to reduce the working intensity of the shooting personnel and improve the automation degree of the vehicle camera lifting assembly 100.

[0059] Since different vehicles have different heights, in order to enable the vehicle camera lifting assembly 100 to adapt to different vehicles, in this embodiment, the length of the mounting rod 1 in its length direction is adjustable. With such a setting, through the length of the mounting rod 1, the vehicle camera lifting assembly 100 can adapt to vehicles of different heights, improving the usage range of the vehicle camera lifting assembly 100. At the same time, the length of the mounting rod 1 is adjustable, so as to shorten the length of the mounting rod 1, which helps to improve the portability of the vehicle camera lifting assembly 100 and avoid the problem of difficult carrying due to the excessive length of the mounting rod 1.

[0060] Further, the mounting rod 1 includes an upper fixed sleeve rod 12 and a lower fixed sleeve rod 13. The lower fixed sleeve rod 13 is sleeved on the lower end of the upper fixed sleeve rod 12, and the length of the lower fixed sleeve rod 13 sleeved inside the upper fixed sleeve rod 12 is adjustable. With such a setting, by adjusting the length of the lower fixed sleeve rod 13 and the upper fixed sleeve rod 12, the mounting rod 1 can be extended or shortened, so that the length of the mounting rod 1 is adjustable.

[0061] Further, the mounting rod 1 further includes a damping ring 14 and a fastening sleeve 15. The damping ring 14 is sleeved outside the lower fixed sleeve rod 13. One end of the damping ring 14 is sleeved inside the upper fixed sleeve rod 12, and the other end extends outside the upper fixed sleeve rod 12 to form a connecting portion. A notch 141 extending along its length direction is provided at the end of the damping ring 14 opposite to the connecting portion. The fastening sleeve 15 is sleeved on the outer peripheral side of the upper fixed sleeve rod 12, and the part of the fastening sleeve 15 extending beyond the upper fixed sleeve rod 12 is limit-mounted with the connecting portion. With such a setting, through the cooperation of the damping sleeve and the fastening sleeve 15, the upper fixed sleeve rod 12 and the lower fixed sleeve rod 13 are fixed, so that the length of the mounting rod 1 is fixed for subsequent shooting. At the same time, through the notch 141, the damping ring 14 can generate radial deformation, so that the damping ring 14 adapts to the lower fixed sleeve rod 13.

[0062] To facilitate the operator to operate the mounting rod 1, the vehicle-mounted camera lifting assembly 100 further includes a mounting seat 3, two connecting arms 5 and two operating rods 6. The mounting seat 3 is provided at the upper end of the mounting rod 1 and has two horizontally upward opposite first ends and two opposite second ends. The two connecting arms 5 are respectively detachably mounted on the two opposite first ends of the mounting seat 3. The two operating rods 6 both extend along the arrangement direction of the two opposite second ends. Each operating rod 6 is provided at the end of the connecting arm 5 away from the mounting seat 3. With such a setting, through the two connecting arms 5, the two operating rods 6 adapt to the operator's arms, so that the operator can operate the vehicle-mounted camera lifting assembly 100. It can be understood that there are various ways to operate the vehicle-mounted camera lifting assembly 100 by the operating rod 6. It can be to operate the mounting rod 1 to rotate, or to operate the mounting rod 1 to tilt forward or backward, so as to adjust the shooting position of the shooting device and enable the shooting device to achieve multi-angle shooting.

[0063] Further, in one embodiment, a rotating hole is formed at one end of the operating rod 6. The vehicle camera lifting assembly 100 further includes a rotating shaft detachably installed at the end of the connecting arm 5 away from the mounting seat 3. Wherein, the rotating shaft rotatably penetrates through the rotating hole, and is arranged in this way to rotatably mount the operating rod 6 on the connecting arm 5, so that the operating rod 6 can adapt to the forward or backward inclination of the mounting rod 1.

[0064] It should be noted that there are various detachable connection methods between the connecting arm 5 and the mounting seat 3.
