Abstract

Provided in the present disclosure is an image acquisition assembly, which belongs to the technical field of image acquisition, and can at least partially solve the problems in the existing art. The image acquisition assembly of the present disclosure includes: an attachment unit configured to be attached onto a display surface of a display screen; and an image acquisition unit connected to the attachment unit and configured to acquire an image on the display surface at a position where the attachment unit is located.

Claims (61)

1 . An image acquisition assembly, comprising:

an attachment unit configured to be attached onto a display surface of a display screen; and

an image acquisition unit connected to the attachment unit, and the image acquisition unit is configured to face the display surface and acquire an image of the display surface at a position where the attachment unit is located.

2 . The image acquisition assembly according to claim 1 , characterized in that the attachment unit comprises:

a housing having a cavity inside and an attachment port in communication with the cavity, wherein when the housing is placed on the display surface with the attachment port facing the display surface, the display surface closes the attachment port in a hermetic seal manner; and

a moving structure in the cavity, wherein the moving structure is movable between a first position and a second position, and an outer side surface of the moving structure maintains the hermetic seal with an inner side of the housing during movement of the moving structure; and the second position is a position in the cavity farther away from the attachment port than the first position.

3 . The image acquisition assembly according to claim 2 , characterized in that

the image acquisition unit is disposed in the cavity and configured to acquire the image of the display surface through the attachment port.

4 . The image acquisition assembly according to claim 3 , characterized in that

the image acquisition unit is fixedly connected to the moving structure.

5 . The image acquisition assembly according to claim 4 , characterized in that

the image acquisition unit comprises a drive circuit board and a lens projecting from one side of the drive circuit board;

the moving structure comprises a first moving member and a second moving member mutually connected, wherein the first moving member has an opening, and the first moving member is located on a side of the second moving member close to the attachment port; and

the drive circuit board is sandwiched between the first moving member and the second moving member, and the lens passes through the opening in the first moving member.

6 . The image acquisition assembly according to claim 5 , characterized in that

a first sealing member is provided between an outer side surface of the lens and an inner side surface of the opening in the first moving member.

7 . The image acquisition assembly according to claim 2 , characterized in that

the image acquisition unit is fixedly disposed on a side of the second position away from the attachment port; and

the moving structure is made of a transparent material.

8 . The image acquisition assembly according to claim 2 , characterized in that

the housing is made of an opaque material,

the attachment unit comprises a suction disk attached to the display surface,

a second sealing member is disposed on an edge of the housing corresponding to the attachment port, and

a third sealing member is disposed between the outer side surface of the moving structure and the inner side surface of the housing.

9 . The image acquisition assembly according to claim 2 , further comprising:

a locking structure configured to at least lock the moving structure when the moving structure is in the second position.

10 . The image acquisition assembly according to claim 2 , characterized in that

the housing further has an operation port in communication with the cavity, and the operation port and the attachment port are positioned at two opposite ends of the cavity; and

the attachment unit further comprises an operation structure connected to a side of the moving structure facing away from the attachment port, and the operation structure extends out of the housing from the operation port.

11 . The image acquisition assembly according to claim 10 , characterized in that

a locking structure is connected to the operation structure at a position outside the housing, and the locking structure is configured to at least contact the housing to lock the moving structure when the moving structure is in the second position.

12 . The image acquisition assembly according to claim 11 , characterized in that

the housing comprises a rear wall opposite to the attachment port, and the operation port is provided on the rear wall; and

the locking structure comprises a locking member and an elastic member; wherein the elastic member is disposed between a rear wall and the moving structure, and when the moving structure is in the second position, the elastic member applies a pressure toward the attachment port to the moving structure; and the locking member is configured to at least contact one side of the rear wall facing away from the attachment port to lock the moving structure when the moving structure is in the second position.

13 . The image acquisition assembly according to claim 12 , characterized in that

the elastic member is a spring sleeved outside the operation structure.

14 . The image acquisition assembly according to claim 12 , characterized in that

the locking member is rotationally connected to the operation structure through a rotation shaft;

the locking member has a first contact surface and a second contact surface, a distance between the second contact surface and the rotation shaft is greater than a distance between the first contact surface and the rotation shaft; and a difference of the distance between the second contact surface and the rotation shaft and the distance between the first contact surface and the rotation shaft, is equal to a distance between the first position and the second position; and

when the locking member is rotated such that the first contact surface contacts a side of the rear wall facing away from the attachment port, the locking member is configured to lock the moving structure in the first position; and when the locking member is rotated such that the second contact surface contacts the side of the rear wall facing away from the attachment port, the locking member is configured to lock the moving structure in the second position.

15 . The image acquisition assembly according to claim 1 , further comprising:

an engagement unit configured to be engaged with the display screen; wherein

the attachment unit is connected to the engagement unit.

16 . The image acquisition assembly according to claim 15 , characterized in that the engagement unit comprises:

a clamp comprises a first branch and a second branch spaced apart from each other, and a connection part connecting the first branch and the second branch, wherein the first branch and the second branch are configured to clamp the display screen therebetween, and the first branch is located on a display surface side of the display screen; wherein

the attachment unit is connected to the first branch.

17 . The image acquisition assembly according to claim 16 , characterized in that the engagement unit further comprises a compression screw and a gasket;

the second branch is provided with a screw hole matched with the compression screw; and

the compression screw passes through the screw hole, and the compression screw is connected to the gasket at an end close to the first branch.

18 . The image acquisition assembly according to claim 15 , further comprising:

a bracket unit on which the display screen is disposed; wherein

the engagement unit is connected to the bracket unit.

19 . An image acquisition assembly, comprising:
