Description

Technical Field

[0001] This invention belongs to the field of image acquisition technology, and specifically relates to an image acquisition component. Background Technology

[0002] Traditionally, in order to obtain the image displayed on the screen, the camera can be pre-positioned at a distance from the screen. After obtaining the displayed image, post-processing such as image clipping can be used to obtain the desired local / global image.

[0003] To obtain a partial image, the camera can be pre-set at a position far from the display screen, aimed at the area on the screen where the image is to be captured, and then focused before taking the picture. However, the above method requires setting the camera according to the position of the display screen; and if the display screen rotates or shifts, the shooting position may be incorrect or the focus may be inaccurate, requiring corresponding adjustments to the camera, which is cumbersome; in addition, because the distance between the camera and the display screen is relatively far, people or objects may enter between the camera and the display screen, obstructing the shooting path.

Detailed Implementation

[0069] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0070] It is understood that the specific embodiments and accompanying drawings described herein are merely for explaining the invention and are not intended to limit the invention.

[0071] It is understood that, without conflict, the various embodiments of the present invention and the features thereof can be combined with each other.

[0072] It is understood that, for ease of description, the accompanying drawings of this invention only show the parts related to the embodiments of this invention, while the parts unrelated to the embodiments of this invention are not shown in the drawings.

[0073] In some related technologies, it is necessary to use a camera to capture images of a local area displayed on a screen.

[0074] For example, in the grading process of electronic exam papers, the screen displays the electronic exam paper for people to grade, and at the same time, the camera needs to capture the image of the name on the exam paper so that the person corresponding to the exam paper can be identified through image analysis and the person can be matched with the score.

[0075] For example, to ensure the accuracy of the displayed content, a camera can be used to capture an image of a corner of the display screen (such as a specific QR code pre-added to that position) to determine whether the image at that position is correct (e.g., whether it is a specific QR code), and whether the display screen is still displaying normally (e.g., whether it is shut down due to a malfunction or has a distorted display), and whether the specific content displayed is correct.

[0076] Of course, it should be understood that the specific applications that require capturing images of a local area of ​​the display screen are not limited to the examples above.

[0077] Reference Figure 1 In some related technologies, after setting up the display screen 19, the camera (i.e., the image acquisition unit 11) can be set at a specific position far away from the display screen 19, and aimed at the area on the display screen 19 where the image is to be acquired. The camera is then focused and taken. After the image is acquired, the desired local / global image is obtained through post-processing, such as image clipping.

[0078] However, the above methods require pre-setting the camera according to the position of the display screen and adjusting the focus, which is cumbersome.

[0079] Furthermore, if the display screen rotates or shifts after the camera is set up, it may cause the camera to be positioned incorrectly or to lose focus, resulting in the inability to accurately capture images. This necessitates readjusting the camera's position, which is cumbersome. Moreover, in many cases, it is impossible to guarantee that the camera can be adjusted in a timely manner after the display screen rotates or shifts (for example, it is obviously impossible to have someone dedicated to adjust the numerous display screens in many public places at all times), which may result in the camera being unable to capture correct images for an extended period of time.

[0080] In addition, because the distance between the camera and the display screen is relatively far in the above methods, people or objects may enter the area between the camera and the display screen, blocking the camera's shooting path, which will also prevent the camera from capturing the required image.

[0081] Firstly, referring to Figures 2 to 10 This invention provides an image acquisition component.

[0082] The image acquisition component of this embodiment of the invention is used to be disposed on the display screen 19, so that the image acquisition unit 11 therein is aligned with a specified local area of ​​the display surface of the display screen 19, and acquires the image displayed in the local area.

[0083] The display screen 19 is a product capable of displaying images and has a display surface for displaying images. For example, the display screen 19 may be a plate-like structure, and at least one of the two main opposing sides of the plate-like structure has a display surface.

[0084] In this embodiment of the invention, the specific type of display screen 19 to which the image acquisition component is applied is not limited. For example, the display screen 19 can be any product with display function, such as a liquid crystal display panel (LCD), an organic light-emitting diode (OLED) display panel, a monitor, electronic paper, a mobile phone, a tablet computer, a television, a laptop computer, a digital photo frame, or a navigator.

[0085] In some embodiments, the image acquisition component of this invention can be used on a display screen 19 installed in a public place.

[0086] That is, the image acquisition component of this embodiment is particularly suitable for display screens 19 installed in public places, such as display screens on subways, display screens on buses, advertising display screens, etc.

[0087] The image acquisition component of this invention includes: a bonding unit for bonding to the display surface of the display screen 19; and an image acquisition unit 11 connected to the bonding unit for acquiring an image of the display surface at the location of the bonding unit.

[0088] The bonding unit refers to a structure that can be "bonded" (e.g., adsorbed) onto the display surface of the display screen 19 in any way.

[0089] In some embodiments, the image acquisition component of the present invention is used to display a screen 19 with a smooth surface, and further used to display a screen 19 with a flat surface.

[0090] Obviously, "fitting" is generally easier to achieve on smooth surfaces, especially on flat surfaces. Therefore, the image acquisition component of this embodiment is particularly suitable for display screens 19 with smooth display surfaces (and further, flat display surfaces).

[0091] Of course, it is also feasible if the display surface of the display screen 19 is curved, or if the display surface is bendable and deformable, thus potentially deforming into various different shapes.

[0092] Image acquisition unit 11 refers to any device that can realize image acquisition function, such as a camera that captures continuous images, or a camera that captures individual images at intervals.

[0093] In this embodiment of the invention, the image acquisition unit 11 is connected to the bonding unit, so that when the bonding unit is bonded to the display surface of the display screen 19, the image acquisition unit 11 can capture the image displayed on the display surface at the location of the bonding unit.

[0094] The image acquisition component of this embodiment includes a bonding unit and an image acquisition unit 11 connected to each other. The bonding unit can be bonded to any desired position on the display surface of the display screen 19, so that the image acquisition unit 11 can acquire the image displayed on the display surface at the position of the bonding unit (i.e., any desired position).

[0095] As can be seen, attaching the bonding unit to the display surface of the display screen 19 at the position where the image needs to be captured is equivalent to setting the image acquisition unit 11 (such as a camera) at the required position. Therefore, the image acquisition unit 11 can directly acquire images without the need to set up the image acquisition unit 11 and focus separately, which makes the operation simple.

[0096] Meanwhile, when the display screen 19 rotates or shifts, the bonding unit and the image acquisition unit 11 naturally rotate or shift in the same way. The relative position of the image acquisition unit 11 and the display screen 19 remains unchanged. Therefore, the image acquisition unit 11 can still be naturally aligned with the area of ​​the display screen 19 where the image needs to be acquired, and the focus is accurate. There is no need to manually adjust the image acquisition unit 11. The operation is simple and can ensure that the correct image is acquired at any time.

[0097] In addition, since the image acquisition unit 11 is directly connected to the display screen 19 through the bonding unit, the distance between it and the display screen 19 is very short. Usually, no people or objects will enter between the image acquisition unit 11 and the display screen 19, so it will not affect the shooting.

[0098] In some embodiments, the bonding unit includes: a housing 2 having a cavity 21, the housing 2 having a bonding opening 211 communicating with the cavity 21; when the housing 2 is disposed on the display surface with the bonding opening 211 facing the display surface, the display surface can airtightly close the bonding opening 211; a movable structure 3 located in the cavity 21, the movable structure 3 being movable between a first position and a second position, and the outer side of the movable structure 3 maintaining an airtight seal with the inner side of the housing 2 during the movement; the second position is a position in the cavity 21 that is further away from the bonding opening 211 than the first position.

[0099] Reference Figures 4 to 6 As one embodiment of the present invention, the above-mentioned bonding unit may include a housing 2 with an internal cavity 21 (i.e., hollow), the housing 2 having a "bonding opening 211" communicating with the internal cavity 21. Furthermore, the shape of the edge (or the "outer ring" of the bonding opening 211) of the housing 2 matches the shape of the display surface of the corresponding display screen 19, for example, referring to... Figures 4 to 6 If the display surface is a plane, then the edge of the fitting opening 211 of the housing 2 is also located in a plane. Therefore, when the housing 2 is placed on the display surface with the fitting opening 211 facing the display surface (i.e., the fitting opening 211 "presses" against the display surface), the edge of the fitting opening 211 of the housing 2 is in contact with the display surface at all positions, so that the fitting opening 211 is "closed" by the display surface, forming an airtight structure.

[0100] Meanwhile, the housing 2 is also provided with a movable structure 3 that can reciprocate in a direction away from or close to the fitting opening 211, for example, a structure that moves in a direction perpendicular to the display surface; moreover, during the movement of the movable structure 3, its outer surface can maintain an airtight seal with the inner surface of the housing 2.

[0101] Therefore, referring to Figure 3 When the moving structure 3 is located closer to the fitting opening 211 (refer to...) Figure 3 When the distance between the housing 2 and the fitting opening is X1, in the first position (release position), the fitting opening 211 of the housing 2 can be "pressed" against the display surface and closed by the display surface; then, referring to Figure 5 This moves the movable structure 3 to a position further away from the fitting opening 211 (see reference). Figure 5The second position (bonding position) is located at a distance of X2 from the bonding opening. Since the housing 2 and the display surface, as well as the housing 2 and the moving structure 3, are kept airtight, no gas will enter the enclosed space (part of the cavity 21) defined by the display surface, housing 2, and moving structure 3 during the above movement. Therefore, as the moving structure 3 moves, the above space gradually expands and the air pressure in it gradually decreases. Eventually, the housing 2 will be "pressed" or "adsorbed" onto the display surface due to the air pressure difference between this space and the external environment. In other words, the bonding unit is bonded to the display surface.

[0102] As can be seen, for the above-mentioned bonding unit, as long as the bonding port 211 of the housing 2 is placed on the display surface and the moving structure 3 is moved from the first position to the second position, the bonding process can be completed naturally, and the operation is simple.

[0103] Of course, the specific shapes of the shell 2 and the movable structure 3 described above are varied. For example, the shell 2 can be referred to as... Figure 2 , Figure 3 The basic shape is "cylindrical", so the cavity 21 inside is also basically "cylindrical (such as cylindrical, prismatic, etc.)"; while the movable structure 3 can slide back and forth in the "cylindrical" shape, similar to a "piston".

[0104] In some embodiments, the image acquisition unit 11 is disposed in the cavity 21 and is used to acquire images of the display surface through the fitting port 211.

[0105] Reference Figures 2 to 7 As one embodiment of the present invention, the image acquisition unit 11 may be disposed in the cavity 21 of the housing 2, so that it needs to acquire the image displayed on the display surface through the fitting port 211.

[0106] The above methods can make the overall shape of the image acquisition component regular (that is, the shape of the housing 2), saving the space occupied by the image acquisition component; on the other hand, they can also make the image acquisition unit 11 located inside the housing 2, which can play a certain protective role.

[0107] Of course, it is also feasible to connect the image acquisition unit 11 to the housing 2 (fitting unit) in other ways. For example, the image acquisition unit 11 can also be connected to the side of the housing 2, thus being located outside the cavity 21.

[0108] In some embodiments, the image acquisition unit 11 is fixedly connected to the movable structure 3.

[0109] Reference Figures 2 to 6 As one embodiment of the present invention, when the image acquisition unit 11 is located inside the housing 2, it may be disposed on the above-mentioned movable structure 3, so that the image acquisition unit 11 will move with the movement of the movable structure 3.

[0110] For example, as one embodiment of the present invention, the focal length of the image acquisition unit 11 can be preset to ensure that when the moving structure 3 is in the second position (fitting position), the focal point of the image acquisition unit 11 is exactly located at the fitting opening 211, that is, exactly on the display surface. Thus, once the fitting operation is completed, it is equivalent to automatically completing the focusing of the image acquisition unit 11 at the same time, which can further simplify the operation.

[0111] In some embodiments, the image acquisition unit 11 includes a drive circuit board 111 and a lens 112 protruding from one side of the drive circuit board 111.

[0112] The movable structure 3 includes a first movable member 31 and a second movable member 32 connected to each other. The first movable member 31 has an opening 311 and is located on the side of the second movable member 32 near the fitting opening 211.

[0113] The drive circuit board 111 is sandwiched between the first moving part 31 and the second moving part 32, and the lens 112 passes through the opening 311 of the first moving part 31.

[0114] Reference Figure 2 , Figure 3 As one embodiment of the present invention, the image acquisition unit 11 may specifically include a lens 112, which includes lenses and the like, for forming an optical path for acquiring images; the lens 112 is disposed on a plate-shaped drive circuit board 111, which is provided with various circuits and electronic devices for driving the lens 112 to work, so as to realize image acquisition, and also serves to support the lens 112.

[0115] Of course, refer to Figure 8 , Figure 10 The image acquisition unit 11 can also be connected (such as to the drive circuit board 111) to lead wires 113, etc., for powering the image acquisition unit 11 and outputting the image signals acquired by the image acquisition unit 11.

[0116] Accordingly, refer to Figure 2 , Figure 3 The moving structure 3 includes two moving parts: a first moving part 31 and a second moving part 32. Both moving parts can be plate-shaped and can be connected to each other, so that the drive circuit board 111 of the image acquisition unit 11 can be "clamped and fixed" between the two moving parts. At the same time, the first moving part 31, which is closer to the fitting port 211 in the moving structure 3, is also provided with an opening 311 for the lens 112 of the image acquisition unit 11 to pass through in order to acquire the image of the display surface.

[0117] Reference Figure 2 , Figure 3Specifically, the two moving parts can be connected together by multiple screws (four in the figure as an example) passing through the first moving part 31 and the second moving part 32 (actually also passing through the drive circuit board 111).

[0118] Of course, there are various ways to connect the first moving part 31 and the second moving part 32. For example, the first moving part 31 and the second moving part 32 can also be connected by snap-fitting, bonding or other methods, as long as they can be connected and the circuit board of the image acquisition unit 11 is fixed between them. This will not be described in detail here.

[0119] In some embodiments, the first moving member 31, the second moving member 32, and the drive circuit board 111 may each be provided with matching alignment protrusions 391 and alignment notches 392.

[0120] For example, refer to Figure 2 , Figure 3 As one way of referring to the reference, the drive circuit board 111 may be provided with a alignment protrusion 391 protruding toward the second moving member 32, and the second moving member 32 is provided with an alignment notch 392. The alignment protrusion 391 can be engaged in the alignment notch 392. Thus, when assembling the moving structure 3 and the image acquisition unit 11, the correctness of the assembly can be ensured simply by aligning the alignment protrusion 391 and the alignment notch 392 with each other, and the stability of the structure can also be improved.

[0121] Of course, although Figure 2 , Figure 3 The following is an example of a drive circuit board 111 having an alignment protrusion 391 and a second moving part 32 having an alignment notch 392. However, it is also possible if the specific components where the alignment protrusion 391 and the alignment notch 392 are located change, which will not be described in detail here.

[0122] In some embodiments, a first sealing member 71 is provided between the outer side of the lens 112 and the inner side of the opening 311 of the first moving member 31.

[0123] Reference Figure 2 , Figure 3 When the lens 112 of the image acquisition unit 11 passes through the opening 311 on the first moving member 31, in order to avoid air leakage at the contact position between the two and affect the bonding (such as adsorption) effect, a first sealing member 71 (such as a sealing ring) can also be provided between the two.

[0124] Of course, it should be understood that the specific forms of the image acquisition unit 11 and the moving structure 3, as well as the connection methods between them, are diverse and not limited to the examples above. For example, the moving structure 3 may be a plate-shaped moving part that is hermetically sealed to the inner side of the housing 2, and the image acquisition unit 11 may be directly connected (e.g., by bonding, snap-fitting, etc.) to the side of the moving part near the fitting opening 211.

[0125] In some embodiments, the image acquisition unit 11 is fixedly disposed at the second position on the side away from the fitting opening 211; the moving structure 3 is made of transparent material.

[0126] Reference Figure 7 As another embodiment of the present invention, the image acquisition unit 11 can also be fixedly disposed in the cavity 21 of the housing 2, and located further away from the fitting opening 211 than the second position (i.e., more than the moving structure 3) (for example, directly fixed to the inner bottom of the housing 2), and the moving structure 3 is transparent, so that the image acquisition unit 11 can "through" the transparent moving structure 3 to acquire the image of the display surface. In this way, the relative position of the image acquisition unit 11 and the fitting opening 211 is more fixed, which is more conducive to achieving accurate focusing.

[0127] Of course, it should be understood that it is also feasible to set the image acquisition unit 11 in other positions. For example, the image acquisition unit 11 can also be set closer to the fitting opening 211 than the first position (i.e., than the moving structure 3), such as being set directly on the inner side of the housing 2.

[0128] Of course, it should be understood that the specific connection methods of the above image acquisition unit 11 are also diverse, such as snap-fit, adhesive, etc., which will not be described in detail here.

[0129] In some embodiments, the housing 2 is made of an opaque material.

[0130] As one embodiment of the present invention, the material of the housing 2 can be opaque, for example, the housing 2 can be made of materials such as plastic or metal. In this way, when the housing 2 is attached to the display surface, it can "block" the location where the image is to be captured, preventing the outside world from seeing the image displayed on the display surface at that location. On the one hand, it can play a role in confidentiality, and on the other hand, it can also prevent the image at that location from interfering with the display effect. For example, this location can display specific identification marks (such as the QR code mentioned above), instead of conventional display content.

[0131] In some embodiments, the housing 2 is provided with a second sealing element 72 at the edge corresponding to the fitting opening 211.

[0132] Reference Figure 2 , Figure 3 The housing 2 is usually made of rigid material, and the display surface of the display screen 19 is also usually rigid. In order to ensure that the display surface can effectively seal the fitting opening 211, a second sealing element 72 (such as a silicone gasket) can be provided on the outer edge of the housing 2 corresponding to the fitting opening 211, or in other words, a second sealing element 72 can be "put on" the fitting opening 21.

[0133] In some embodiments, a third seal 73 is provided between the outer side of the movable structure 3 and the inner side of the housing 2.

[0134] To ensure that the movable structure 3 can maintain a good airtight seal with the housing 2 when it moves, a third sealing element 73 (such as a sealing ring) can be provided between the outer side of the movable structure 3 and the inner side of the housing 2. For example, the third sealing element 73 can be sleeved on the side of the movable structure 3.

[0135] Of course, the specific form of the third seal 73 should match the form of the moving structure 3. For example, refer to Figure 2 , Figure 3 When the movable structure 3 includes a first movable member 31 and a second movable member 32, and the drive circuit board 111 is sandwiched between the two movable members, the third sealing member 73 is also sleeved on the side of the drive circuit board 111. For example, the third sealing member 73 may have two grooves, which are respectively used for the edge parts of the first movable member 31 and the drive circuit board 111 to be inserted to improve the sealing effect.

[0136] In some embodiments, the image acquisition component further includes a locking structure, which is used to lock the moving structure 3 when the moving structure 3 is in the second position.

[0137] When the bonding unit is in the bonding state (the moving structure 3 is in the second position), the air pressure on the side of the moving structure 3 corresponding to the external environment is greater, so it will be subjected to a force that pushes it to the first position. In order to ensure that the moving structure 3 can automatically stabilize in the second position to maintain the bonding state, a locking structure can be set to fix the moving structure 3 in the second position.

[0138] The specific forms of the locking structure are diverse, and will be described in detail later.

[0139] In some embodiments, the housing 2 further has an operation port 212 communicating with the cavity 21, the operation port 212 and the fitting port 211 being located at opposite ends of the cavity 21; the fitting unit further includes an operation structure 4, which connects to the moving structure 3 on the side opposite to the fitting port 211 and extends out of the housing 2 from the operation port 212.

[0140] Reference Figures 2 to 6 The moving structure 3 is located on the side opposite to the fitting opening 211. Figures 2 to 6 Specifically, the second moving part 32 (located away from the mating opening 211) can also be connected to an operating structure 4, which can be used as a reference. Figures 2 to 6 The operating mechanism 4 is in the form of a lever, which extends out of the housing 2 through the operating port 212 located at the opposite end of the housing 2 and the fitting port 211. The user can grasp the operating structure 4 and "drive" the moving structure 3 to move, so as to switch the fitting unit between the fitting state and the release state, which is easy to operate.

[0141] Meanwhile, due to the presence of the operating port 212, the portion of the cavity 21 located on the side of the moving structure 3 away from the fitting port 211 is connected to the external environment. The air in the cavity will not be compressed or expanded due to the movement of the moving structure 3, nor will it experience pressure changes.

[0142] Of course, the methods for implementing operations on the moving structure 3 are not limited to this. For example, one can also refer to... Figure 7 The bonding unit does not have the above-mentioned operating structure and operating port. Instead, it moves by attracting magnetic devices located outside the housing 2 (correspondingly, the moving structure 3 should also include magnetic devices), or by driving driving devices located inside the housing 2. These methods will not be described in detail here.

[0143] In some embodiments, the operating structure 4 is connected to a locking structure at a position outside the housing 2, and the locking structure is used at least to contact the housing 2 to lock the moving structure 3 when the moving structure 3 is in the second position.

[0144] As one embodiment of the present invention, the above locking structure can be connected to the above operating structure 4 (such as the operating lever) at a position outside the housing 2, so that the locking structure can "lock" on the housing 2 when the moving structure 3 is in the second position, so as to play the role of positioning the moving structure 3.

[0145] In some embodiments, the housing 2 includes a rear wall 22 opposite to the fitting opening 211, and an operating opening 212 is located on the rear wall 22; the locking structure includes a locking member 51 and an elastic member 52; the elastic member 52 is disposed between the rear wall 22 and the movable structure 3, and when the movable structure 3 is in the second position, the elastic member 52 can apply pressure to the movable structure 3 pointing towards the fitting opening 211; the locking member 51 is at least used to contact the side of the rear wall 22 away from the fitting opening 211 when the movable structure 3 is in the second position to lock the movable structure 3.

[0146] Reference Figures 2 to 6 As one embodiment of the present invention, the housing 2 may have a rear wall 22 (which may be a reference). Figure 2 , Figure 3 The rear wall 22 is separable (or integral with other parts of the housing 2), and the operation port 212 is provided on the rear wall 22. Moreover, an elastic member 52 is provided between the rear wall 22 and the moving structure 3 (such as between the rear wall 22 and the second moving member 32). When the moving structure 3 is in the second position, the elastic member 52 is in a compressed state, thereby applying a force to the moving structure 3 towards the fitting port 211; at this time, the locking member 51 of the locking structure is pulled by the operating structure 4 and is stuck on the rear wall 22, thereby preventing the moving structure 3 from moving towards the fitting port 211 and locking the moving structure 3.

[0147] In some embodiments, the elastic element 52 is a spring sleeved outside the operating structure 4.

[0148] Reference Figures 2 to 6 Specifically, the elastic element 52 can be a spring sleeved outside the operating structure 4 (such as the operating lever), so that the operating structure 4 can, to a certain extent, position the spring and ensure the stability of the spring position.

[0149] In some embodiments, the locking member 51 is rotatably connected to the operating structure 4 via a pivot 519.

[0150] The locking member 51 has a first contact surface 511 and a second contact surface 512. The distance between the second contact surface 512 and the rotating shaft 519 is greater than the distance between the first contact surface 511 and the rotating shaft 519. The difference between the distance between the second contact surface 512 and the rotating shaft 519 and the distance between the first contact surface 511 and the rotating shaft 519 is equal to the distance between the first position and the second position.

[0151] When the locking member 51 rotates to the point where the first contact surface 511 contacts the side of the rear wall 22 away from the fitting opening 211, it is used to lock the moving structure 3 in the first position; when the locking member 51 rotates to the point where the second contact surface 512 contacts the side of the rear wall 22 away from the fitting opening 211, it is used to lock the moving structure 3 in the second position.

[0152] As one embodiment of the present invention, the locking member 51 (such as a handle) can be connected to the operating structure 4 (as shown in the reference) via a pivot 519. Figure 2 , Figure 3 The rotating shaft 519 can be inserted into the holes in the locking member 31 and the operating structure 4 and fixed by a nut. Therefore, the locking member 51 can rotate relative to the operating structure 4 (such as the operating lever). When the locking member 51 rotates to different positions, it contacts the rear wall 22 through two different contact surfaces (the first contact surface 511 and the second contact surface 512), and the distance between these two contact surfaces and the rotating shaft 519 (i.e., the connection between the locking member 51 and the operating structure 4) is different.

[0153] Therefore, referring to Figure 3 The fitting opening 211 of the housing 2 can be "pressed" against the display surface of the display screen 19. At this time, the locking member 51 rotates until the first contact surface 511 contacts the rear wall 22. Since the distance between the first contact surface 511 and the rotating shaft 519 is relatively short, the rotating shaft 519 is relatively close to the rear wall 22. That is, the part of the operating structure 4 outside the housing 2 is relatively short, and the part inside the housing 2 is relatively long. Thus, the moving structure 3 is locked in the first position close to the fitting opening 211 and away from the rear wall 22, and the fitting unit is in the released state.

[0154] When bonding is required, please refer to Figure 4The locking member 51 pulls the operating structure 4 to move away from the display screen 19, causing the moving structure 3 to move away from the fitting port 211, reducing the gas in the space defined by the display surface, the inner side of the housing 2, and the moving structure 3, thus achieving fitting; at the same time, the locking member 51 is rotated so that its second contact surface 512 faces the rear wall 22.

[0155] Then, refer to Figure 5 Release the locking member 51. Under the action of the elastic member 52 and the air pressure difference, the second contact surface 512 of the locking member 51 contacts the rear wall 22. Since the distance between the second contact surface 512 and the rotating shaft 519 is relatively long, that is, the rotating shaft 519 is far away from the rear wall 22, the part of the operating structure 4 outside the housing 2 is relatively long, and the part inside the housing 2 is relatively short. Thus, the moving structure 3 is locked in the second position away from the fitting port 211 and close to the rear wall. The fitting unit enters the fitting state and is fitted onto the display surface and remains stable. The image acquisition unit 11 can start to acquire images.

[0156] To remove the bonding unit from the display surface, the locking member 51 can be pulled again and rotated so that the first contact surface 511 faces the rear wall 22. After release, the first contact surface 511 naturally contacts the rear wall 22, the moving structure 3 returns to the first position, the pressure difference between the inside of the bonding unit and the external environment disappears, the bonding unit returns to the released state, and can be removed from the first contact surface 511 towards the rear wall 22.

[0157] As can be seen from the above method, the housing 2 can be switched between the fitting state and the release state simply by pulling the locking member 51 and making a simple rotation. Moreover, the fitting unit can maintain stability on its own in both the fitting state and the release state, so its operation is simple.

[0158] Of course, the specific form of the locking structure is not limited to this; it can also be any other structure that can lock the movable structure 3 in the second position.

[0159] In some embodiments, the bonding unit includes a suction cup for bonding to the display surface.

[0160] As another embodiment of the present invention, the bonding unit can also be a suction cup that can be directly bonded to the display surface, and the image acquisition unit 11 can be connected to the suction cup (for example, connected to the connecting rod behind the suction cup).

[0161] Of course, the specific form of the bonding unit is not limited to the examples of housing 2 and suction cup above; it can also be any other structure that can be bonded to the display surface.

[0162] In some embodiments, the image acquisition component further includes: a snap-fit ​​unit 6 for snap-fit ​​connection to the display screen 19; and an adhesion unit connected to the snap-fit ​​unit 6.

[0163] Reference Figures 8 to 10 As one embodiment of the present invention, the image acquisition component may further include a snap-fit ​​unit 6 that can be snapped onto the display screen 19, and the aforementioned bonding unit (the outer shell 2 visible in the figure) is also connected to the snap-fit ​​unit 6 (as shown in the figure). Figure 8 (Connected by two screws). Thus, when the snap-fit ​​unit 6 is connected to the display screen 19, it is equivalent to fixing the bonding unit at a specific position on the display surface of the display screen 9. At the same time, the bonding unit itself is also bonded to that position, thereby making the positioning of the bonding unit (including the image acquisition unit 11 connected to it) more stable.

[0164] In some embodiments, the engaging unit 6 includes: a clamping member 61, which includes a first branch 611 and a second branch 612 spaced apart, and a connecting portion 613 connecting the first branch 611 and the second branch 612, the first branch 611 and the second branch 612 being used to clamp the display screen 19 between them, and the first branch 611 being located on one side of the display surface of the display screen 19; and an bonding unit being connected to the first branch 611.

[0165] Reference Figure 8 The locking unit 6 may specifically include two branches (first branch 611 and second branch 612) located on both sides of the display screen 19, and the two branches are connected by a connecting part 613. The bonding unit is connected to the branch (first branch 611) located on one side of the display surface. Alternatively, the locking unit 6 is similar to a "clip" that can be clamped onto the display screen 19, and the bonding unit is connected to one of the clips.

[0166] In some embodiments, the engaging unit 6 further includes a clamping screw 62 and a washer 631; the second branch 612 is provided with a screw hole 6121 that matches the clamping screw 62; the clamping screw 62 passes through the screw hole 6121 and is connected to the washer 631 at one end near the first branch 611.

[0167] Reference Figure 8 The locking unit 6 may also include a clamping screw 62, and the branch (second branch 612) corresponding to the back side of the display screen 19 (the side away from the display surface) is provided with a screw hole 6121 that matches the clamping screw 62. The clamping screw 62 passes through the screw hole 6121 and can be tightened to different degrees according to the thickness of the display screen 19, thereby clamping the display screen 19 between the clamping screw 62 and the first branch 611 (that is, the bonding unit). In order to avoid excessive pressure applied to the display screen 19 by the clamping screw 62, a gasket 631 (such as a silicone gasket) can also be connected to the end of the clamping screw 62 that contacts the display screen 19.

[0168] Of course, refer to Figure 8The engaging unit 6 may also include other structures, such as a clamping member 632 for accommodating the above-mentioned gasket 631.

[0169] In some embodiments, the image acquisition component further includes: a support unit 8, a display screen 19 for mounting on the support unit 8; and a locking unit 6 connected to the support unit 8.

[0170] Reference Figure 9 , Figure 10 As one embodiment of the present invention, the image acquisition component may further include a support unit 8, and the display screen 19 is directly mounted on the support unit 8.

[0171] For example, the display screen 19 can be an advertising display screen, which is fixed on and supported by the bracket unit 8, so that the bracket unit 8 and the display screen 19 together can form an "advertisement".

[0172] As can be seen, the position of the display screen 19 relative to the bracket unit 8 is fixed; at the same time, the locking unit 6 is also connected to the bracket unit 8, so the position of the locking unit 6 relative to the bracket unit 8 is also fixed. Therefore, the locking unit 6 can more effectively ensure that the bonding unit is fixed in a specific position on the display screen 19.

[0173] The specific connection methods between the display screen 19 and the bracket unit 8, as well as the specific connection methods between the locking unit 6 and the bracket unit 8, are varied. For example, refer to... Figure 9 The bracket unit 8 is an "outer frame" surrounding each side of the display screen 19, and the locking unit 6 includes the aforementioned "clamp"-type locking member 61, and the connecting part 613 of the "clamp" is connected to one side of the "outer frame"; further, referring to Figure 8 , Figure 10 The locking member 61 can also "hold" the display screen 19 from the side to make its positioning between the display screen 19 more stable. For example, the locking member 61 can be connected to the bracket unit 8 and "hold" the display screen 19 through a structure (not shown in the figure) including the above-mentioned clamping screw, screw hole, gasket, clamping member, etc.

[0174] Of course, the specific forms of the support unit 8 and the engaging unit 6 are not limited to these, and will not be described in detail here.

[0175] Secondly, referring to Figure 11 , Figure 12 This invention provides an image acquisition component.

[0176] The image acquisition component of this embodiment of the invention is used to be disposed on the display screen 19, so that the image acquisition unit 11 therein is aligned with a specified local area of ​​the display surface of the display screen 19, and acquires the image displayed in the local area.

[0177] The image acquisition component of this invention is particularly suitable for display screens 19 installed in public places, such as display screens on subways, display screens on buses, and advertising display screens.

[0178] The image acquisition component of this invention includes: a locking unit 6 for locking onto the display screen 19; and an image acquisition unit 11 connected to the locking unit 6. When the locking unit 6 is locked onto the display screen 19, the image acquisition unit 11 is located at a predetermined distance from the display surface of the display screen 19, and the image acquisition unit 11 is used to acquire an image of the display surface at its location.

[0179] In this embodiment of the invention, the relative positions of the locking unit 6 and the image acquisition unit 11 are fixed. Therefore, when the locking unit 6 is fixed on the display screen 19, it is equivalent to the image acquisition unit 11 (such as a camera) being set at a specific position relative to the display screen 19. The image acquisition unit 11 can directly acquire the image of the required area of ​​the display surface without the need to set up the image acquisition unit 11 and focus separately, which makes the operation simple.

[0180] Meanwhile, when the display screen 19 rotates or shifts, the locking unit 6 and the image acquisition unit 11 naturally rotate or shift in the same way. The relative position of the image acquisition unit 11 and the display screen 19 remains unchanged. Therefore, the image acquisition unit 11 can still be naturally aligned with the area of ​​the display screen 19 where the image needs to be acquired, and the focus is accurate. Thus, there is no need to manually adjust the image acquisition unit 11, making the operation simple and ensuring that the correct image can be acquired at any time.

[0181] In addition, since the image acquisition unit 11 is directly connected to the display screen 19 through the snap-fit ​​unit 6, the distance between it and the display screen 19 is very short. Usually, no people or objects will enter between the image acquisition unit 11 and the display screen 19, so it will not affect the shooting.

[0182] In some embodiments, the locking unit 6 includes: a clamping member, which includes a first branch and a second branch spaced apart, and a connecting portion connecting the first branch and the second branch, the first branch and the second branch being used to clamp the display screen 19 between them, and the first branch being located on one side of the display surface of the display screen 19; the image acquisition unit 11 is connected to the first branch.

[0183] As one embodiment of the present invention, the engaging unit 6 may also include the above-mentioned components. Figure 8 As shown, the clamping member is in the form of a "clamp" consisting of a connecting part and two branches, and at this time the image acquisition unit 11 (not the bonding unit) is directly connected to one of the branches of the clamp corresponding to the display surface.

[0184] Of course, the card-connecting unit 6 may further include the above. Figure 8The clamping screw, screw hole, gasket, clamping parts, and other structures shown will not be described in detail here.

[0185] In some embodiments, the image acquisition component further includes: a support unit 8, a display screen 19 for mounting on the support unit 8; and a locking unit 6 connected to the support unit 8.

[0186] Reference Figure 9 As one embodiment of the present invention, the image acquisition component of the present invention may also include the above-mentioned support unit 8, and the display screen 19 may be disposed on the support unit 8. For example, the support unit 8 and the display screen 19 together form an "advertisement board"; and the locking unit 6 is also connected to the support unit 8 so as to make the connection between the locking unit 6 and the display screen 19 more stable.

[0187] The specific forms of the locking unit 6 and the support unit 8 are varied. For example, the support unit 8 can be in the form of the "outer frame" mentioned above, while the locking unit 6 can be in the form of the above... Figure 8 The clamping screw and other structures are connected to the support unit 8, which will not be described in detail here.

[0188] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
