Description

Technical Field

[0001] The present invention relates to the field of video lenses, and particularly to an image capturing device. Background Art

[0002] With the popularization of remote collaboration and online education, external display video lenses have become key devices for real-time image transmission.

[0003] In the prior art, such devices are usually clamped and fixed on the top of the display screen, and they usually only provide a single forward shooting angle, defaulting to face the user's face; when displaying desktop items, the lens needs to be disassembled and held by hand to adjust the lens orientation. When sharing a handwriting scenario, the user needs to always hold the lens and look down at the desktop to capture the writing process, which is inconvenient to operate and affects the smoothness of collaboration.

[0004] Existing solutions do not fully consider structural lightweight, cost, and user operation experience. For example, the patent document CN210687685U proposes to control the lens angle adjustment by the user operating the motor and the spherical structure, which relies on electric drive and control programs, has a high cost and complex operation, and poor user experience.

[0005] Therefore, it is necessary to design a new type of image capturing device to improve the above defects. Summary of the Invention

[0006] The purpose of the present invention is to provide an image capturing device, which uses a mechanical linkage structure to realize the adjustment of the shooting angle of the camera lens. The user can push the slider with one hand, and through the coordinated action of the rotating member and the transmission member, a single linear movement can be converted into the rotation of the lens, realizing the rapid switching of the shooting angle of the camera lens, instant scene switching, simple operation, and effectively improving the user experience.

[0007] To achieve the above object, the present invention provides an image capturing device, including a camera lens;

[0012] Wherein, when the slider is moved, the slider drives the carrier to displace, and the transmission member drives the rotating member to rotate circumferentially, so as to drive the carrier to displace along the moving direction of the slider and pivot relative to the slider, thereby realizing the adjustment of the shooting direction of the camera lens.

[0013] Preferably, the first direction is perpendicular to the display surface of the display screen, and the slider is movably arranged between a first position and a second position;

[0014] Wherein, when the slider is located at the first position, the camera lens faces the area facing the display surface; and,

[0015] When the slider is operated to move from the first position to the second position, the transmission member drives the rotating member to rotate, so as to drive the carrier to move towards the direction facing the display surface and pivot relative to the slider, so that the camera lens faces the plane where the display screen is placed.

[0016] Preferably, the rotating member is a first gear, and the transmission member is a rack meshing with the first gear; the slider moves along the first direction to drive the first gear to roll along the first direction on the rack, so as to drive the carrier to pivot relative to the slider.

[0018] A first connecting rod, extending along the first direction and having one end hinged to the base;

[0019] A second connecting rod, having a relative third end and a fourth end, the third end being pivotally connected to the other end of the first connecting rod, and,

[0020] A second gear, fixedly connected to the fourth end, the second gear meshing with the first gear; the slider moves along the first direction to drive the second gear to pivot, and further drives the first gear to pivot relative to the slider.

[0021] Preferably, the rotating member is a first wheel body, and the transmission member includes:

[0022] A fixed block, fixedly arranged on the base, and the fixed block has a groove;

[0023] A second wheel body, rotatably arranged on the slider, and,

[0024] An endless belt, extending and arranged along the first direction, the first wheel body and the second wheel body are drivingly connected by the endless belt, and a part of the endless belt is inserted into the groove and engaged with the inner wall of the groove;

[0025] Wherein, when the slider is operated to move along the first direction, the slider drives the annular belt to roll relative to the first wheel body and the second wheel body, so as to drive the first wheel body and the second wheel body to rotate, and enable the carrier to pivot relative to the slider.

[0026] Preferably, a damping pivot connection is provided between the carrier and the slider, and the rotating member rotates to drive the carrier to pivot or stop and position relative to the slider.

[0027] Preferably, the base includes:

[0028] A first clamping member, the slider is slidably disposed on the first clamping member along the first direction, and the first clamping member has a stop surface; and,

[0034] Compared with the prior art, the image capturing device provided by the present invention uses a mechanical linkage adjustment method to realize the adjustment of the shooting angle of the lens, and the structure is simple and reliable. By pushing the slider to move along the first direction, the slider drives the carrier to move synchronously, and the rotating member fixed to the second end of the carrier rotates. Furthermore, the rotating member drives the lens carrier to pivot relative to the slider, realizing the conversion of the linear motion of the slider into the rotational motion of the lens carrier, without relying on electric drive and complex control programs, and the operation is simple. The user can move the slider with one hand to seamlessly switch the camera lens from shooting the user's face to looking down at the desktop (such as displaying a handwriting scene or desktop items), without disassembly or hand-held adjustment, and is suitable for occasions such as video conferencing, online teaching, and live broadcast that require flexible adjustment of the shooting angle, effectively improving the use experience.

[0044] In the specification and claims, certain terms are used to refer to specific elements. Those of ordinary skill in the art should understand that manufacturers may use different terms to refer to the same element. The specification and claims do not use the difference in names as a way to distinguish elements, but use the difference in functions of elements as the criterion for distinction. The term "comprising" mentioned throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to".

[0045] Please refer to Figures 1 - 3 , Figure 1 An assembly schematic diagram of the image capturing device 1 and the display screen 3 proposed by the present invention, Figure 2 A cross-sectional schematic view of the image capturing device 1 according to an embodiment of the present invention, Figure 3 is Figure 2 A cross-sectional schematic view when the sliding member 11 of the image capturing device in

[0046] The image capture device 1 proposed in the present invention is fixed to an object (the object in the present invention is a display screen 3 as an example), and can adjust the shooting direction of its camera lens 2. The above-mentioned image capture device 1 also includes a base 10, a sliding member 11, a supporting member 12 and a transmission member. The above-mentioned base 10 is preferably arranged on the top edge of the display screen 3, and the sliding member 11 is slidably arranged on the base 10 along the first direction D1. The user can push the sliding member 11 along the first direction D1 with one hand. The above-mentioned supporting member 12 has a first end and a second end opposite to each other, wherein the first end is used to hold the camera lens 2, the second end is pivotally connected to the sliding member 11, and a rotating member is fixedly arranged on the second end of the above-mentioned supporting member 12. The transmission member extends along the above-mentioned first direction D1 and is fixedly installed on the base 10, the above-mentioned rotating member is coupled and in contact with the transmission member, and a rotational connection is formed between the rotating member and the transmission member.

[0047] Specifically, when the user pushes the sliding member 11 with one hand to move it along the first direction D1, the sliding member 11 drives the supporting member 12 to move synchronously, and the rotating member fixed to the second end of the supporting member 12 is driven by the transmission member on the base 10 to rotate, so that the supporting member 12 is displaced along the moving direction of the sliding member 11 and pivots relative to the sliding member 11, thereby adjusting the shooting direction of the camera lens 2.

[0048] The image capture device 1 proposed by the present invention uses a mechanical linkage adjustment method to adjust the shooting direction of the camera lens 2. The structure is lightweight and does not require electric drive. The user can quickly switch the shooting angle by pushing and pulling the sliding member 11 with one hand, without disassembly or hand-held adjustment. It is suitable for various occasions that require flexible adjustment of the shooting angle, effectively improving the user experience. In addition, it is understandable that the user can also directly manually bend the camera lens 2 to adjust the angle of the camera lens 2 to meet the needs of different usage scenarios and improve operational flexibility.

[0049] In one of the embodiments, the first direction D1 is defined as a display surface S1 perpendicular to the display screen 3, wherein the positive direction + is the direction facing the user side / display surface, and the negative direction - is away from the user side. The sliding member 11 is linearly movable along this direction between the first position and the second position. For example, in one possible embodiment, limit members (not shown) are respectively provided at both ends of the extension direction of the base 10, corresponding to the first position and the second position, respectively, so as to limit the movement range of the sliding member 11 along the first direction D1, but the present invention is not limited thereto. Among them, if Figure 1 and 2As shown, when the slider 11 is in the first position, the carrier 12 and the camera lens 2 are preferably parallel to the display surface S1, and the camera lens 2 faces the area in front of the front surface of the display screen 3. When the user pushes the slider 11 in the positive direction of the first direction D1 from the first position to the second position, the contact force between the rotating member and the transmission member is converted into a rotational torque, causing the carrier 12 to pivot around the second end. During this process, the camera lens 2 at the first end of the carrier 12 gradually deflects from the initial state of facing the area facing the display surface S1 until the lens looks down on the plane area (i.e., the desktop) where the display screen 3 is placed. In addition, when the slider 11 returns from the second position to the first position, reverse transmission between the rotating member and the transmission member drives the carrier 12 to reset, effectively realizing the rapid switching of the camera lens 2 between the "forward shooting" and "overhead shooting" modes. In one embodiment, the angle between the camera lens 2 and the display surface S1 is between 0° and 90°.

[0050] Further, the operation path of the slider 11 conforms to ergonomics, and when the slider 11 moves from the first position ( Figure 2 ) towards the user side to the second position ( Figure 3 ), during the process of adjusting the pitch angle of the lens, it synchronously moves horizontally towards the user side. This displacement causes the center point of the lens to avoid the projection area of the bracket of the display screen 3 and can effectively improve the integrity of the content displayed on the desktop.

[0051] Please refer to Figures 2 - 3 shown in the first embodiment, the above mechanical linkage method selects a meshing transmission structure of a gear and a rack. Specifically, the rotating member is a first gear 13a fixed to the second end of the carrier 12, and the transmission member is a rack 13b extending along the above first direction D1. Preferably, the tooth pitch and modulus of the first gear 13a and the rack 13b are matched to ensure smooth meshing transmission between the first gear 13a and the rack 13b during sliding movement.

[0052] As Figure 2 shown, in this embodiment, when the user pushes the slider 11 to move in the positive direction of the first direction D1, the slider 11 drives the overall displacement of the carrier 12 and drives the first gear 13a fixed to the second end of the carrier 12 to roll along the tooth surface of the rack 13b, generating a rotational motion. Since the second end of the carrier 12 is pivotally connected to the slider 11, the rotational torque of the first gear 13a drives the carrier 12 and the camera lens 2 to rotate counterclockwise in the Z-X direction (as shown by the arrow A in Figure 2 ), as Figure 3 shown, in this embodiment, when the slider 11 moves to the second position, the carrier 12 pivots to turn the camera lens 2 to look down on the desktop area.

[0053] In addition, it can be understood that when the user moves the slider 11 in the negative direction of the first direction D1 (away from the user side), at this time, the first gear 13a rolls reversely along the tooth surface of the rack 13b, and the rotational torque of the gear drives the carrier 12 and the camera lens 2 to rotate clockwise in the X-Z direction (as Figure 2 shown by arrow A').

[0054] Please refer to Figures 4 - 5 In the second embodiment shown, the above mechanical linkage method selects a double-link and double-gear structure. Specifically, the rotating member is the first gear 14a fixed to the second end of the carrier 12, and the transmission member includes the second gear 14b, the first link 14c, and the second link 14d. The first link 14c extends integrally along the first direction D1, and one end thereof is hinged to the base 10. The second link 14d has opposite third and fourth ends, and its third end is pivotally connected to the other end of the first link 14c. The second gear 14b is fixedly connected to the fourth end of the second link 14d.

[0055] Referring to Figures 4 to 5 shown, when the slider 11 moves along the first direction D1, the carrier 12 and the first gear 14a are displaced. Since the first gear 14a meshes with the second gear 14b, the second gear 14b and the second link 14d pivot and swing, and the first link 14c swings around the hinge axis. During this process, the pivotal swing of the second gear 14b drives the first gear 14a to rotate, thereby driving the carrier to pivot clockwise / counterclockwise. As Figure 5 shown, in this embodiment, when the slider 11 moves to the second position in the positive direction of the first direction D1 (towards the user side), the camera lens 2 rotates counterclockwise in the Z-X direction to switch to the top view mode.

[0056] The above mechanical meshing linkage method proposed by the present invention is simple and compact, has high transmission accuracy, can achieve stable angle switching, and reduces the manufacturing cost.

[0057] Please refer to Figures 6 - 7In the third embodiment shown, the above-mentioned mechanical linkage method uses a pulley transmission structure. The above-mentioned rotating member is the first wheel body 15a, and the transmission member includes a second wheel body 15b, a fixed block 15c and an annular belt 15d. Among them, the above-mentioned fixed block 15c is fixedly installed on the base 10, and the fixed block 15c has a groove body. The overall projection direction of the annular belt 15d extends along the first direction D1. The second wheel body 15b is rotatably arranged on the sliding member 11. The second wheel body 15b is opposite to the first wheel body 15a. The first wheel body 15a and the second wheel body 15b are connected by the annular belt 15d, and part of the annular belt 15d is passed through the groove body and engaged with the inner wall of the groove body. When the sliding member 11 moves along the first direction D1, the annular belt 15d is forced to roll relative to the first wheel body 15a and the second wheel body 15b, driving the first wheel body 15a and the second wheel body 15b to rotate, thereby causing the carrier 12 and the camera lens 2 to pivot relative to the sliding member 11. Figure 7 As shown, in this embodiment, when the sliding member 11 moves to the second position along the positive direction of the first direction D1 (towards the user side), the first wheel body 15a and the second wheel body 15b rotate counterclockwise along the ZX direction, thereby driving the carrier 12 and the camera lens 2 to pivot to switch to the top-view mode. In addition, in other embodiments, the above-mentioned rotating member and transmission member can also select other structures as needed, and the present invention is not limited to the rotating member and transmission member described in the above-mentioned embodiments 1 to 3.

[0058] Furthermore, in one of the embodiments, the supporting member 12 and the sliding member 11 may be connected by a damping pivot connection to ensure that the supporting member 12 can be stopped and positioned at any angle to meet the requirements of multi-angle framing and avoid the camera lens 2 from being randomly offset due to gravity or external forces.

[0059] Please refer to Figure 1 , Figure 2 and Figure 8 As shown, in one embodiment, the base 10 includes a first clamping member 101 and a second clamping member 102. The sliding member 11 is movably disposed on the first clamping member 101 along the first direction D1, the first clamping member 101 has a stop surface S2, and the second clamping member 102 has a connecting end 102a and a free end 102b, and the connecting end 102a is rotatably pivoted to the first clamping member 101. The stop surface S2 of the first clamping member 101 is used to abut against the top of the front frame of the display surface S1, and the free end of the second clamping member 102 abuts against the rear shell of the display screen 3.

[0060] Preferably, the second clamping member 102 further has a counterweight 103. The free end 102b of the second clamping member 102 is pressed against the rear case of the display screen 3 by the counterweight 103. The contact surface between the second clamping member 102 and the rear case of the display screen 3 is designed as an arc surface, and a silicone gasket 104 can be attached as needed to adapt to the rear cases of display screens 3 with different curvatures and prevent scratching the surface during clamping. When clamping display screens 3 with different thicknesses, the second clamping member 102 rotates adaptively around the pivot point, and stable clamping and movement are achieved through the gravity of the counterweight 103 and the friction of the silicone gasket 104.

[0061] In summary, the imaging capture device 1 provided by the present invention realizes the adjustment of the shooting angle of the lens by means of mechanical linkage adjustment. The user pushes the slider 11 to move along the first direction D1 with one hand to form an initial driving force. Through the cooperation of the rotating member and the transmission member, the linear displacement of the slider 11 can drive the carrier 12 to displace along the moving direction of the slider 11 and pivot relative to the slider 11, realizing a rapid switching of the shooting angle of the imaging lens 2 (for example, switching from shooting the user's face to looking down at the desktop), without the need for disassembly or hand adjustment, and is suitable for occasions such as video conferencing, online teaching, live broadcast, etc. that require flexible adjustment of the shooting angle, effectively improving the user experience.

[0062] The present invention has been described by the above related embodiments. However, the above embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention fall within the scope of patent protection of the present invention.
