In order to improve the problem that the internal structure of the structure for rotating the video lens is complex, which leads to difficult repair and poor appearance caused by exposed structure, the application provides a rotating mechanism and a corresponding rotary photographing structure, which can be applied to the video lens.

Please refer to fig. 1. Fig. 1 is a view of a rotating photographic structure 200 according to an embodiment of the application disposed on a display 300.

Fig. 1 shows a display 300 and a rotation photographing structure 200 disposed on the display 300. Display 300 is, for example, a display device of a computer device. In some embodiments, when a user is making a video or live broadcast via a computer device, the rotating photographic arrangement 200 may be positioned on top of the display 300, as shown in fig. 1, secured to the bezel 310 of the display 300. Thus, the rotary photographing structure 200 can photograph images of a user in front of the display 300, thereby implementing a video or live broadcast service.

Please refer to fig. 1 and fig. 2 at the same time. Fig. 2 is an enlarged view of a portion R of the rotation photographing structure 200 of fig. 1. As shown in fig. 1 and 2, in an embodiment of the present application, the rotation photographing structure 200 includes a rotation mechanism 100, and the rotation photographing structure 200 is fixed to a bezel 310 on top of a display 300 through the rotation mechanism 100. The rotary photographic arrangement 200 further comprises a photographic arrangement 210, the photographic arrangement 210 comprising an electrical wire 240. In some embodiments, the electrical wires 240 are used to power the rotating photographic structure 200, or the rotating photographic structure 200 transmits signals outwards through the electrical wires 240.

It should be noted that the rotation photographing structure 200 shown in fig. 1 and fig. 2 is only an example, and the protection scope of the present application should not be excessively limited. In some embodiments, the rotation photographing structure 200 can be disposed outside the display 300.

In some embodiments, the rotation mechanism 100 of the rotation photographing structure 200 can be independently disposed for fixing devices or apparatuses other than the photographing device 210.

Please refer to fig. 3. Fig. 3 is an exploded view of a rotation photographing structure 200 according to an embodiment of the application. As described above, in the present embodiment, the rotation imaging structure 200 includes the imaging device 210 and the rotation mechanism 100.

In the present embodiment, the photographing device 210 includes a housing 220, a lens 230, and an electric wire 240. The electric wire 240 is provided to supply power to components inside the housing 220 of the photographing device 210 or to transmit signals to the outside of the photographing device 210. For the purpose of detailed description, the housing 220 of the rotary photographing structure 200 is shown in cross section, and the components disposed in the housing 220 are also shown in cross section to better understand the composition of the rotary photographing structure 200.

The housing 220 includes a receiving hole 225 at the bottom thereof, the receiving hole 225 being provided to assemble the photographing device 210 on the rotation mechanism 100, and the housing 220 being able to cover the top of the rotation mechanism 100 so as to shield a portion of the rotation mechanism 100 from being exposed.

As shown in fig. 3, in the present embodiment, the rotation mechanism 100 includes a foot stand 110, a carrier 130, a wear-resistant member 150, a spring 170, and a screw 180 for fixing. The screw 180 sequentially fixes the spring 170, the wear-resistant member 150, and the carrier 130 on the stand 110 from top to bottom. Such that one end of the spring 170 abuts the screw 180 and the other end of the spring 170 abuts the wear member 150. In the present embodiment, the spring 170 is compressed, so that the spring 170 applies a force to the bearing seat 130 through the wear-resistant member 150 to press the bearing seat 130 against the stand 110.

Since the carrier 130 includes the elongated sliding groove 133 (see fig. 4 later), when the carrier 130 abuts against the stand 110, the carrier 130 can still slide back and forth through the sliding groove 133. In the present embodiment, the housing 220 of the photographing device 210 is substantially fixed to the supporting base 130 of the rotating mechanism 100 through the accommodating hole 225. Thus, the photographing device 210 can slide back and forth on the stand 110 through the sliding groove 133 of the carrying seat 130.

To further illustrate the composition of a rotary mechanism 100 of the present application, please refer to both fig. 4 and fig. 5. Fig. 4 is an exploded view of a rotary mechanism 100 according to an embodiment of the application. Fig. 5 is a perspective view of a rotary mechanism 100 according to an embodiment of the application.

As shown in fig. 4 and 5, in the present embodiment, the rotation mechanism 100 includes a foot stand 110, a carrier 130, a wear-resistant member 150, a spring 170, and a fixing screw 180.

The stand 110 includes a curved surface S1 and a bracket 113 protruding from the curved surface S1. As shown in fig. 4, the bracket 113 protrudes from the curved surface S1 in the vertical direction D3. The top of the bracket 113 includes a screw hole 116. Screw hole 116 is provided to fix screw 180.

As described above, the carrier 130 includes the sliding groove 133 and two engaging members 136 disposed on two sides of the sliding groove 133. The engaging member 136 is used for fixing the photographing device 210 on the carrier 130. The sliding groove 133 is configured to slide the carrying base 130 and the photographing device 210 fixed on the carrying base 130 back and forth. As shown in fig. 4, the chute 133 is elongated, and the chute 133 extends in the direction D1. In addition, the sliding groove 133 includes a curved surface S2 and a curved surface S3 opposite to each other, and the curved surface S2 of the sliding groove 133 is disposed to abut against and slidably fit with the curved surface S1 of the stand 110, which will be described in detail later.

In the present embodiment, when the bearing seat 130 is disposed on the long curved surface S1 of the stand 110, the bracket 113 of the stand 110 will protrude from the chute 133, and the curved surface S2 of the chute 133 will abut against the curved surface S1. In this way, the bearing seat 130 can slide back and forth on the curved surface S1 through the chute 133.

In fig. 4, a projection of the elongated curved surface S1 in the direction D1 is elongated, so as to further limit the sliding direction of the carrier 130 along the chute 133 to be in the direction D1.

In the present embodiment, the curved surfaces S1 and S2 are both arc-shaped portions, but the present application is not limited thereto. In this way, the bearing seat 130 can slide back and forth on the curved surface S1 of the arc until one end of the chute 133 abuts against the bracket 113. The carrier 130 slides forward, for example, corresponding to the front direction of the display 300 (as shown in fig. 1), so that the carrier 130 slides toward the user. In such an embodiment, the range of sliding of the carrier 130 back and forth can be defined by an angle. In some embodiments, the range of sliding of the carriage 130 back and forth is less than 90 degrees.

In some embodiments, the forward sliding range of the carrier 130 is 50 degrees, the backward sliding range of the carrier 130 is 30 degrees, and the total forward and backward sliding range is 80 degrees. In this way, the sliding range of the bearing seat 130 is asymmetric, so as to limit the bearing seat 130, so as to avoid misalignment caused by excessive backward sliding.

In the present embodiment, the shape of the entire carrier 130 may be considered as a semicircle. In the embodiment where the rotation mechanism 100 is disposed on the display 300 (as shown in fig. 1), considering that the frame 310 of the display 300 has a thickness, the sliding range of the bearing seat 130 is limited by the sliding groove 133, so that the semicircular bearing seat 130 can be prevented from colliding with the frame 310 of the display 300, so as to reduce damage and increase stability.

The spring 170 is disposed on the carrier 130 to apply a force to the carrier 130, so that the carrier 130 abuts against the stand 110. After the carrier 130 is slid back and forth to a desired angle to enable the components (e.g., the camera 210) on the carrier 130 to meet the user's requirements, the carrier 130 can be fixed at the desired angle due to the springs 170 abutting the carrier 130 against the foot stand 110.

In the present embodiment, the screw 180 is used as a fixing member to fix the spring 170 and the carrier 130 to the bracket 113 of the stand 110. The screw thread portion 182 of the screw 180 is locked to the screw hole 116 on the top surface of the bracket 113. Thus, one end of the spring 170 abuts against the head 181 of the screw 180 to force the bearing seat 130 downward in the opposite direction D3. It should be noted that the present application is not limited to the fixing member, and other components that can be used to fix and support the spring 170 against are also included in the scope of the present application.

As shown in fig. 4, in the present embodiment, the wear-resistant member 150 is disposed between the spring 170 and the carrier 130. The bracket 113 of the foot stand 110 passes through a circular hole in the center of the wear member 150. The spring 170 applies a force to the carrier 130 through the wear member 150.

The wear member 150 will prevent the spring 170 from directly wearing the carrier 130 during rotation. In the present embodiment, the wear member 150 includes a curved surface S4 and an abutment surface S5. After assembly, the curved surface S4 of the wear-resistant member 150 abuts against and slidably fits against the curved surface S3 of the bearing seat 130. The abutting surface S5 of the wear member 150 is opposite to the curved surface S4, and the abutting surface S5 is a plane extending in the direction D1 and the direction D2, so as to abut the spring 170, wherein the direction D1 and the direction D2 are perpendicular to the direction D3. This facilitates the downward force of the spring 170 to urge the carrier 130 against the foot rest 110.

In this way, when the bearing seat 130 slides back and forth, the wear-resistant member 150 is fixed relative to the foot stand 110. The curved surface S4 of the wear member 150 and the curved surface S1 of the stand 110 jointly clamp the chute 133 of the bearing seat 130 by the downward force of the spring 170. The curved surface S2 of the chute 133 abuts against and slidably engages with the curved surface S1 of the foot stand 110 and the curved surface S4 of the wear-resistant member 150, respectively, with the curved surface S3.

In the present embodiment, referring to fig. 4, the spring 170, the wear member 150 and the bearing seat 130 are removed from the stand 110 together by removing the screw 180. Thus, the assembly and the disassembly are convenient and the maintenance is facilitated.

Please refer to fig. 5 and fig. 6 simultaneously. Fig. 6 is a cross-sectional view of a rotation photographing structure 200 according to an embodiment of the application, wherein the rotation photographing structure 200 is disposed on a frame 310 of a display 300. Fig. 6 shows the photographing device 210 disposed on the rotating mechanism 100 of fig. 5, and the rotating mechanism 100 is disposed on the frame 310 of the display 300.

As shown in fig. 6, in the rotation mechanism 100, the bracket 113 passes through the bearing seat 130, the curved surface S2 of the chute 133 of the bearing seat 130 abuts and slidably abuts against the curved surface S1 of the foot stand 110, and the curved surface S3 of the chute 133 abuts and slidably abuts against the curved surface S4 of the wear member 150. One end of the spring 170 abuts against the screw 180, and the other end of the spring 170 abuts against the abutment surface S5 of the wear member 150. The spring 170 is compressed to apply force to the bearing seat 130 through the wear-resistant member 150, so that the chute 133 of the bearing seat 130 abuts against the foot stand 110.

In fig. 6, the housing 220 of the photographing device 210 is fixed to the carrying base 130 through the receiving hole 225. In detail, in the present embodiment, the carrier 130 has two opposite engaging members 136 located on two sides of the chute 133 in the direction D1, and the two engaging members 136 respectively clamp the edges of the receiving hole 225 of the housing 220.

In the present embodiment, however, the chute 133 extends beyond the curved surface S1 in the direction D1. In this way, the housing 220 substantially completely covers the curved surface S1 of the stand 110 of the rotation mechanism 100, and the components (including the bearing seat 130, the wear-resistant member 150, the spring 170 and the screw 180) other than the stand 110 of the rotation mechanism 100 are all located on the curved surface S1. Thus, the housing 220 covers all components of the rotation mechanism 100 except the foot stand 110, reducing the appearance of the rotation mechanism 100 due to the exposed components.

In the cross section shown in fig. 6, it is noted that the length of the chute 133 is not the same in the direction D1 around the bracket 113. That is, the sliding range of the carriage 130 and the photographing device 210 disposed thereon is asymmetric. With the bracket 113 as a center, the chute 133 reserves a greater length in the direction D1 (corresponding to the rear of the display 300), and the chute 133 reserves a smaller length in the direction opposite to the direction D1 (corresponding to the front of the display 300). Thus, the carrying base 130 and the photographing device 210 disposed thereon can slide forward by a larger angle, and the user is prevented from excessively sliding the photographing device 210 to the rear of the display 300, so that the user in front of the display 300 cannot be photographed.

Please refer to fig. 7 and fig. 8 simultaneously. Fig. 7 and 8 are a perspective view and a cross-sectional view of a photographing device 210 of the rotary photographing structure 200 according to an embodiment of the application.

Fig. 7 and 8 show an embodiment in which the photographing device 210 slides forward on the carriage 130. As can be seen from fig. 7 and 8, since the chute 133 has a larger length reserved rearward about the bracket 113, the rotation photographing structure 200 can slide forward of the display 300 by a larger angle.

In some embodiments, if the standard positions of the photographing device 210 and the carrier 130 are defined in fig. 6, the photographing device 210 and the carrier 130 in fig. 8 slide 50 degrees in front of the display 300 with respect to fig. 6, and the other end of the carrier 130 abuts against the stand 113.

Fig. 9 and 10 are a perspective view and a cross-sectional view of a photographing device 210 of a rotary photographing structure 200 according to an embodiment of the application.

Fig. 9 and 10 show an embodiment in which the photographing device 210 slides backward on the carriage 130. As can be seen from fig. 9 and 10, since the chute 133 is reserved for a smaller length forward with respect to the bracket 113, the sliding angle of the rotation photographing structure 200 to the rear of the display 300 is smaller.

In some embodiments, if a standard position of the photographing device 210 and the carrier 130 is defined in fig. 6, the photographing device 210 and the carrier 130 in fig. 10 slide 30 degrees backward of the display 300 with respect to fig. 6, and the other end of the carrier 130 abuts against the stand 113.

In summary, the present application provides a rotation mechanism and a corresponding rotation photographing structure. The curved surface of the bearing seat is abutted against the curved surface on the foot rest through the spring and can be slidably attached to the curved surface on the foot rest, so that the bearing seat can slide on the curved surface, and the structure is relatively simple and convenient to maintain. The long strip-shaped sliding groove of the bearing seat can further limit the front and back sliding of the bearing seat. The bearing seat is provided with a photographing device to form a rotary photographing structure, the rotary photographing structure can be used as a video lens to be fixed on a display, the adjustment of a user is convenient, and the bearing seat is provided with a mechanical structure and most of components of the rotary mechanism, so that the bare body is reduced, and the whole is attractive.

Although the present application has been described with reference to the above embodiments, it should be understood that the application is not limited thereto, but may be modified and practiced by those skilled in the art without departing from the spirit and scope of the present application.
