The following describes an embodiment of the background cloth switching mechanism of the present invention, please refer to fig. 1 to 5, which specifically includes:

a main frame body 101, a winding shaft 103 for winding the background cloth 109 is movably arranged on the top of the main frame body 101, the winding shaft 103 can rotate on the main frame body 101, and the upper part of the background cloth 109 can be wound in the winding shaft 103, in the embodiment, one color area on the upper part of the background cloth 109 is stored or released through the forward and reverse rotation of the winding shaft 103; a driving part 104 is mounted on the main frame body 101, wherein the driving part 104 is a motor; the driving element 104 is connected with the reel 103 through a transmission element, the reel 103 is fixed with the top end of the background cloth 109, and the driving element 104 is used for driving the reel 103 to rotate, so that the background cloth 109 can be lifted in the main frame body 101; a middle roller seat is fixedly arranged below the scroll 103, a middle roller 106 is movably arranged in the middle roller seat, the middle roller 106 can rotate in the middle roller seat, a guide rail component 102 vertically arranged on the main frame body 101 is arranged below the middle roller seat, a winding moving mechanism 107 is movably arranged on the guide rail component 102, and the winding moving mechanism 107 can vertically move up and down along the guide rail component 102; the winding moving mechanism 107 is movably provided with a lower roller 108, the lower roller 108 can rotate in the winding moving mechanism 107, and the bottom end of the background cloth 109 is fixedly connected to the winding moving mechanism 107 after sequentially winding into the lower roller 108 and the middle roller 106; the background cloth 109 is divided into two or more areas with different colors.

Preferably, a background area is formed between the reel 103 and the middle reel seat, the background area is a view finding area of the camera device, a background lamp panel 110 is arranged in the background area, and the background cloth 109 covers the outer surface of the background lamp panel 110. In this embodiment, the back light panel 110 is disposed in the main frame 101, and light emitted from the back light panel 110 is emitted after passing through the back cloth 109, so that the background illumination effect is better, and the imaging quality of the photo is effectively improved.

In the present embodiment, the background cloth 109 is divided into two areas of different colors, which are a white area disposed on the upper part of the background cloth 109 and a blue area disposed on the lower part of the background part; when the motor is not powered on, the winding moving mechanism 107 stops at the lower limit position by self weight, at this time, the white area in the background cloth 109 is pulled out from the reel 103 and covered on the surface of the background lamp panel 110, and the blue area in the background cloth 109 is arranged in the area below the background lamp panel 110, so the background color at this time is white; when the motor is powered on, the scroll 103 is driven by the motor to rotate clockwise, at this time, the white area in the background cloth 109 is wound into the scroll 103, and simultaneously, the background cloth 109 drives the winding moving mechanism 107 to move upwards to the upper limit position, at this time, the blue area in the background cloth 109 is lifted and covers the surface of the background lamp panel 110, so that the background color at this time is changed into blue; at this point, the switching of the background color is completed. In the embodiment, since the background cloth switching mechanism is driven by only one driving member 104, the problem that the background cloth 109 is wrinkled or even blocked due to the unmatched speeds of a plurality of driving members in the prior art is effectively solved, the control effect is good, and the service life of the background cloth is also reduced.

Meanwhile, in order to ensure that the background cloth 109 is constantly kept in a tensioned state, when the overall mass of the winding movement mechanism 107 is light, a weight assembly may be further added to the winding movement mechanism 107.

The utility model discloses in, the below activity of spool 103 is equipped with upper roller 111, upper roller 111 locates the top of background lamp plate 110, just the bottom of background cloth 109 winds into extremely through this upper roller 111 after in the well roller 106. And the outer sides of the upper roller 111 and the lower roller 108 are protruded to the outside, so that the background cloth 109 disposed between the upper roller 111 and the lower roller 108 is not connected to the background lamp panel 110 at the rear, thereby preventing friction between the background lamp panel 110 and the background cloth 109 and effectively protecting the background cloth 109.

Optionally, the area of each color region in the background cloth 109 is larger than the area of the background lamp panel 110. In this embodiment, since the area of the background lamp panel 110 is matched with the viewing area of the image capturing device, the area of each color area in the background cloth 109 is larger than the area of the background lamp panel 110, which can effectively prevent two different colors from appearing on the background cloth when a picture is taken because the area of a certain color area is too small; wherein, be equipped with a plurality of LED lamp pearls in this backlight panel 110, this LED lamp pearl can be around setting up on the edge of this backlight panel 110, or set up on backlight panel 110 with vertical or transverse arrangement's mode, and this place does not do not specifically prescribe a limit to.

In this embodiment, the guide rail assembly 102 is provided with more than two position sensors, the number of the position sensors is consistent with the number of the areas with different colors in the background cloth 109, and the background cloth 109 is controlled by the position sensors to stay at a predetermined position, so that the areas with different colors cover the outer side surface of the background lamp panel 110, thereby realizing the switching of multiple background colors. In this embodiment, when the number of the areas with different colors in the background cloth 109 is three, the method includes: white area, blue area, red area; and the number of the position sensors is correspondingly set to three, and each position sensor is respectively arranged at different horizontal heights in the guide rail assembly 102.

Preferably, the number of the position sensors is two, which are an upper position sensor 112 and a lower position sensor 113, respectively, the upper position sensor 112 is disposed on the top of the guide rail assembly 102, and the lower position sensor 113 is disposed on the bottom of the guide rail assembly 102.

In the present embodiment, the guide rail assembly 102 is composed of two guide rails parallel to each other. Since the guide rail assembly 102 has two guide rails, the winding moving mechanism 107 is mounted on the two guide rails at the same time, which makes the winding moving mechanism 107 more stable when sliding, so as to prevent the background cloth 109 from tilting on one side when adjusting up and down.

In this embodiment, the transmission member is a drive belt 105.

In yet another embodiment, the transmission member may also be a drive screw or a drive gear set.

The utility model discloses can also be a photographing system, following and carrying out specific description to it with an embodiment, it specifically includes:

an image pickup apparatus and a background cloth switching mechanism as described above; a background area is arranged between a scroll and a middle roller seat in the background cloth switching mechanism, and a lens of the camera shooting equipment is aligned with background cloth covered on the background area; and the viewing area of the lens is within the background area.

In the embodiment, the background cloth has more than two color areas, and the positions of different color areas in the background cloth are adjusted through a driving piece, so that the proper color areas enter the viewing area of the lens, and the background color for photographing is quickly adjusted; because only drive through a driving piece among the background cloth switching mechanism, it has solved effectively among the prior art because of the speed of a plurality of driving pieces mismatch and lead to the background cloth to corrugate and even block up the condition emergence of blocking, and its control effect is good, has also reduced the life of background cloth simultaneously.
