DETAILED DESCRIPTION

[0030] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1 and Figure 2 The present invention provides a technical solution: an adjustment mechanism of a camera unit, comprising a mounting base 4 for mounting the camera unit, a first box body 1, and a second box body 2 falling on the first box body 1, a first adjustment mechanism 3 capable of rotating and lifting the camera unit is arranged in the first box body 1, a second adjustment mechanism 5 capable of adjusting the shooting angle of the camera unit is arranged in the second box body 2, and the second adjustment mechanism 5 comprises a driving component 51, a moving component 52 and a bidirectional supporting component 53.

[0032] See also Figure 2 and Figure 3 The driving assembly 51 is arranged in the second box body 2. The driving assembly 51 includes a motor 511. The motor 511 is fixed on the inner wall of one side of the second box body 2. A worm 512 is fixed to the output end of the motor 511. A horizontally arranged rotating shaft 513 is rotatably connected in the second box body 2. A worm wheel 514 and a spur gear 515 are coaxially fixed on the rotating shaft 513. The worm 512 is meshed with the worm wheel 514. The motor 511 drives the worm 512 to rotate, and the meshing of the worm 512 and the worm wheel 514 drives the rotating shaft 513 to rotate. The transmission action of the spur gear 515 drives the moving assembly 52 to move vertically in the first box body 1.

[0033] In a preferred embodiment, a first fixed plate 21 is fixed in the second box body 2, and a guide groove for vertically slidingly guiding the rack 522 is provided on the first fixed plate 21. A second fixed plate 22 is fixed on the outer side of the second box body 2, and a slide groove for vertically slidingly limiting the slider 523 is provided on the back side of the second fixed plate 22, which is used to limit the moving direction of the moving component 52 so that the moving component 52 can only move vertically in the first box body 1.

[0034] See also Figure 2 and Figure 6 The movable component 52 can move vertically in the second box body 2 under the drive of the driving component 51. The movable component 52 includes a guide rod 521, which is horizontally arranged and perpendicular to the axial direction of the rotating shaft 513. A rack 522 is fixed to one end of the guide rod 521, and the rack 522 is meshed with the spur gear 515. A slider 523 is fixed to the other end of the guide rod 521. Through the meshing of the spur gear 515 and the rack 522, the rack 522 is guided by the guide groove on the first fixed plate 21, and the slider 523 is limited by the slide groove on the second fixed plate 22, so that the guide rod 521 can move vertically in the second box body 2.

[0035] See also Figure 4 and Figure 5 The two-way holding assembly 53 is driven by the moving assembly 52 to push and pull the mounting seat 4 from two directions to adjust the tilt angle of the camera unit. The two-way holding assembly 53 includes an upper movable plate 531 and a lower movable plate 532, which are respectively hinged to the upper and lower ends of the second fixed plate 22. The outer surfaces of the upper movable plate 531 and the lower movable plate 532 are hinged with first connecting rods 533. One end of the two first connecting rods 533 away from the upper movable plate 531 and the lower movable plate 532 is hinged to the upper and lower ends of the back of the mounting seat 4. The upper movable plate 531 and the lower movable plate 532 are hinged with side plates 534 on both sides through second cross bars 537. The middle positions of the two side plates 534 are hinged with first cross bars 535. The middle position of the first cross bars 535 is fixed with a transversely arranged sliding sleeve 536. The sliding sleeve 536 and the first cross bars 535 are distributed in a cross shape. The sliding sleeve 536 is sleeved outside the guide rod 521. Figure 2In the direction shown, when the guide rod 521 moves upward, the guide rod 521 can guide the sliding sleeve 536 so that the first cross bar 535 can push the side plates 534 on both sides to move to the upper right side. At this time, under the push of the side plates 534 on both sides, the upper movable plate 531 and the lower movable plate 532 can rotate synchronously clockwise at the upper and lower ends of the second fixed plate 22. The first connecting rod 533 connected to the upper movable plate 531 pushes the mounting seat 4 to have a movement tendency to rotate to the right, and the first connecting rod 533 connected to the lower movable plate 532 pushes the mounting seat 4 to have a movement tendency to rotate to the left, thereby adjusting the shooting angle of the camera unit downward. Conversely, when the motor 511 works in reverse, the shooting angle of the camera unit can be adjusted upward.

[0036] See also Figure 2 and Figure 7 , an illumination device 6 for providing a light source for the camera unit in a dark environment is arranged on the outer side of the second box body 2. The illumination device 6 synchronously adjusts the fill light direction for the camera unit under the drive of the two-way supporting assembly 53. An active groove for the activity of the illumination device 6 is arranged on the top of the first box body 1. The tail of the illumination device 6 is hinged in the active groove through a pin shaft 61. Two second connecting rods 62 are also hinged on both sides of the tail of the illumination device 6. The upper ends of the two second connecting rods 62 are hinged on the second cross bar 537 at the bottom of the side plate 534. In the process of adjusting the shooting angle of the camera unit downward, the two side plates 534 move to the upper right side. The second cross bar 537 at the bottom of the two side plates 534 can pull the illumination device 6 to rotate clockwise with the pin shaft 61 as the rotation center by pulling the second connecting rod 62, thereby adjusting the illumination angle of the illumination device 6 downward as the camera unit shoots. Conversely, when the motor 511 works in reverse, the illumination angle of the illumination device 6 can be adjusted upward as the camera unit shoots.

[0037] In a preferred embodiment, a notch is formed at the bottom of the lower movable plate 532 to avoid the second connecting rod 62 , so as to avoid mutual interference caused by the movement of the lower movable plate 532 and the second connecting rod 62 .

[0038] The working principle and use process of the present invention are as follows: when adjusting the shooting angle of the camera unit, the present invention can drive the worm 512 to rotate through the operation of the motor 511, and the engagement of the worm 512 with the worm wheel 514 drives the rotating shaft 513 to rotate, and the spur gear 515 is engaged with the rack 522, and the rack 522 is guided by the guide groove on the first fixed plate 21 and the slider 523 is limited by the slide groove on the second fixed plate 22, so that the guide rod 521 can move vertically in the second box body 2, such as Figure 2In the direction shown, when the guide rod 521 moves upward, the guide rod 521 can guide the sliding sleeve 536, so that the first cross bar 535 pushes the side plates 534 on both sides to move to the upper right side. At this time, under the push of the side plates 534 on both sides, the upper movable plate 531 and the lower movable plate 532 can be synchronously rotated clockwise at the upper and lower ends of the second fixed plate 22. The first connecting rod 533 connected to the upper movable plate 531 pushes the mounting seat 4 to have a movement tendency to rotate to the right, and the first connecting rod 533 connected to the lower movable plate 532 pushes the mounting seat 4 to have a movement tendency to rotate to the left, thereby adjusting the shooting angle of the camera unit downward. Conversely, when the motor 511 works in reverse, the shooting angle of the camera unit can be adjusted upward. In the above manner, the tilting direction of the mounting seat 4 can be assisted in two different directions to adjust the shooting angle of the camera unit, and the self-locking effect of the worm gear 514 and the worm 512 on the driving assembly 51 is used to further improve the shooting stability of the camera unit.

[0039] In the initial state, if Figure 2 As shown, the lighting direction of the lighting device 6 is basically consistent with the shooting direction of the camera unit installed on the mounting seat 4. When the shooting angle of the above-mentioned camera unit is adjusted downward, the two side panels 534 move to the upper right side, and the second cross bar 537 at the bottom of the two side panels 534 can pull the lighting device 6 to rotate clockwise with the pin shaft 61 as the rotation center by pulling the second connecting rod 62, thereby adjusting the lighting angle of the lighting device 6 downward as the camera unit shoots. Conversely, when the motor 511 works in reverse, the lighting angle of the lighting device 6 can be adjusted upward as the camera unit shoots. In the above manner, the fill light direction of the lighting device 6 to the camera unit can be synchronously adjusted.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
