Please refer to fig. 1. Fig. 1 is a view illustrating a rotational photographing structure 200 disposed on a display 300 according to an embodiment of the present application.

In fig. 1, a display 300 and a rotating camera structure 200 disposed on the display 300 are shown. The display 300 is, for example, a display device of a computer device. In some embodiments, when a user is playing a video or live broadcast via a computer device, the rotating camera structure 200 may be positioned on top of the display 300 and fixed on the frame 310 of the display 300, as shown in fig. 1. Thus, the rotating camera structure 200 can capture images of a user in front of the display 300, thereby implementing video or live broadcast services.

Please refer to fig. 1 and fig. 2 simultaneously. Fig. 2 is an enlarged partial R view of the arrangement of the rotating camera structure 200 of fig. 1. As shown in fig. 1 and fig. 2, in an embodiment of the present application, the rotational photographing structure 200 includes a rotation mechanism 100, and the rotational photographing structure 200 is fixed to a frame 310 on the top of a display 300 through the rotation mechanism 100. The rotating camera structure 200 further includes a camera device 210, the camera device 210 including an electrical wire 240. In some embodiments, the electrical wire 240 is used to supply power to the rotating camera structure 200, or the rotating camera structure 200 transmits signals to the outside through the electrical wire 240.

It should be noted that the rotating photographing structure 200 shown in fig. 1 and fig. 2 is only an example, and the scope of the present application should not be limited by this. In some embodiments, the rotating photographing structure 200 can be disposed on a device other than the display 300.

In some embodiments, the rotation mechanism 100 of the rotating camera structure 200 can also be independently installed to fix devices or apparatuses other than the camera device 210.

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

In the present embodiment, the image pickup device 210 includes a housing 220, a lens 230, and a wire 240. The electrical wire 240 is configured to provide power to components inside the housing 220 of the camera device 210 or transmit signals to the outside of the camera device 210. For the purpose of detailed description, the housing 220 of the rotational photographing structure 200 is shown in cross section, and components disposed in the housing 220 are also shown in cross section, so as to better understand the composition of the rotational photographing structure 200.

The housing 220 includes a receiving hole 225 at the bottom thereof, the receiving hole 225 is configured to assemble the photographing device 210 on the rotating mechanism 100, and the housing 220 can cover the top of the rotating mechanism 100 to shield the rotating mechanism 100 from being partially exposed.

As shown in fig. 3, in the present embodiment, the rotating mechanism 100 includes a foot stand 110, a bearing seat 130, a wear-resistant member 150, a spring 170, and a fixing screw 180. The screw 180 fixes the spring 170, the wear-resistant member 150 and the bearing seat 130 on the stand 110 sequentially 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 force to the load-bearing seat 130 through the wear-resistant member 150 to abut the load-bearing seat 130 against the foot stool 110.

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

For further explanation of the components of a rotating mechanism 100 of the present application, please refer to fig. 4 and fig. 5. Fig. 4 is an exploded view of a rotating mechanism 100 according to an embodiment of the present application. Fig. 5 is a perspective view of a rotating mechanism 100 according to an embodiment of the present disclosure.

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

The foot 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 a perpendicular direction D3. The top of the bracket 113 includes a screw hole 116. The screw holes 116 are provided to fix screws 180.

As mentioned above, the supporting base 130 includes the sliding slot 133 and two engaging members 136 located at two sides of the sliding slot 133. The engaging member 136 is used to fix the photographing device 210 on the supporting base 130. The sliding slot 133 is disposed for the carriage 130 and the photographing device 210 fixed on the carriage 130 to slide back and forth. As shown in fig. 4, the sliding slot 133 is elongated, and the sliding slot 133 extends in a direction D1. In addition, the sliding groove 133 includes a curved surface S2 and a curved surface S3, and the curved surface S2 of the sliding groove 133 is disposed to abut against and slidably attach to the curved surface S1 of the stand 110, as will be described in detail later.

In the present embodiment, when the load-bearing seat 130 is disposed on the elongated curved surface S1 of the foot stool 110, the bracket 113 of the foot stool 110 will protrude from the sliding slot 133, and the curved surface S2 of the sliding slot 133 will abut against the curved surface S1. Thus, the carriage 130 can slide back and forth on the curved surface S1 through the sliding slot 133.

In fig. 4, a projection of the elongated curved surface S1 in the direction D1 is elongated, thereby further limiting the sliding direction of the carriage 130 along the sliding slot 133 to be in the direction D1.

In the present embodiment, the curved surfaces S1 and S2 are both portions of arc surfaces, but the present invention is not limited thereto. Thus, the carriage 130 can slide back and forth on the curved surface S1 until one end of the sliding slot 133 abuts against the bracket 113. The carriage 130 slides forward, which may correspond to a forward direction of the display 300 (as shown in fig. 1), so that the carriage 130 slides toward the user. In such an embodiment, the range of the sliding of the carrier 130 back and forth can be defined by an angle. In some embodiments, the range of the sliding of the carrier 130 back and forth is less than 90 degrees.

In some embodiments, the sliding range of the carrier 130 is 50 degrees forward, the sliding range of the carrier 130 is 30 degrees backward, and the total sliding range is 80 degrees forward and backward. Therefore, the range of the sliding motion of the supporting base 130 is asymmetric to limit the supporting base 130, so as to avoid the user from being unable to align due to excessive sliding motion.

In the present embodiment, the shape of the entire carrier 130 may be considered as a semicircle. In the embodiment of the rotating mechanism 100 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 supporting base 130 is limited by the sliding slot 133, and the semicircular supporting base 130 can be prevented from colliding with the frame 310 of the display 300, so as to reduce the damage and increase the stability.

The spring 170 is disposed on the load-bearing seat 130 to apply a force to the load-bearing seat 130, so that the load-bearing seat 130 abuts against the foot stool 110. When the front and rear sliding supports 130 are slid to a desired angle to satisfy the user's requirement, the supporting supports 130 can be fixed at the desired angle by the springs 170 urging the supporting supports 130 against the stand 110.

In this embodiment, the screw 180 is used as a fixing member to fix the spring 170 and the load-bearing seat 130 to the bracket 113 of the stand 110. The 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 carrier 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 capable of being used for fixing and abutting the spring 170 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 load-bearing seat 130. The bracket 113 of the foot stool 110 passes through a circular hole in the center of the wear member 150. The spring 170 applies 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-resistant member 150 includes a curved surface S4 and an abutting surface S5. After assembly, the curved surface S4 of the wear-resistant member 150 abuts against and is slidably attached to the curved surface S3 of the bearing seat 130. The abutting surface S5 of the wear-resistant member 150 is opposite to the curved surface S4, and the abutting surface S5 is a plane substantially extending in the direction D1 and the direction D2 for the spring 170 to abut against, wherein the direction D1 and the direction D2 are perpendicular to the direction D3. This facilitates the spring 170 to force the load bearing seat 130 downward against the foot rest 110.

In this way, when the carriage 130 slides back and forth, the wear-resistant member 150 is not moved relative to the foot stool 110. The curved surface S4 of the wear-resistant member 150 and the curved surface S1 of the foot stool 110 jointly clamp the sliding slot 133 of the bearing seat 130 by the downward force of the spring 170. The curved surface S2 of the sliding slot 133 abuts against and slidably fits the curved surface S1 of the foot stool 110 and the curved surface S4 of the wear-resistant member 150, respectively, by the curved surface S3.

In the present embodiment, referring to fig. 4, the spring 170, the wear-resistant member 150 and the load-bearing seat 130 can be removed from the foot stand 110 by removing the screw 180. Therefore, the assembly and disassembly are convenient, and the maintenance is facilitated.

Please refer to fig. 5 and fig. 6. Fig. 6 is a cross-sectional view of the rotating photographing structure 200 according to an embodiment of the present application, in which the rotating photographing structure 200 is disposed on a frame 310 of the display 300. Fig. 6 shows the camera 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 rotating mechanism 100, the bracket 113 passes through the supporting seat 130, the curved surface S2 of the sliding slot 133 of the supporting seat 130 abuts against and slidably fits the curved surface S1 of the foot stool 110, and the curved surface S3 of the sliding slot 133 abuts against and slidably fits the curved surface S4 of the wear-resistant 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 a force to the load-bearing seat 130 through the wear-resistant member 150, so that the sliding groove 133 of the load-bearing seat 130 abuts against the foot stool 110.

In fig. 6, the housing 220 of the photographing device 210 is fixed to the carriage 130 through the receiving hole 225. In detail, in the present embodiment, the carriage 130 has two opposite engaging members 136 respectively located at two sides of the sliding slot 133 in the direction D1, and the two engaging members 136 respectively clamp the edge of the accommodating hole 225 of the housing 220.

In the present embodiment, the sliding groove 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 foot rest 110 of the rotating 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 foot rest 110 of the rotating mechanism 100 are located on the curved surface S1. Therefore, the housing 220 covers all components of the rotating mechanism 100 except the foot rest 110, thereby reducing the influence on the appearance caused by the exposed components of the rotating mechanism 100.

In addition, in the cross section shown in fig. 6, it can be noted that the length of the sliding groove 133 is different from the length of the bracket 113 in the direction D1. That is, the slidable range of the carriage 130 and the photographing device 210 disposed thereon is not symmetrical. With the bracket 113 as the center, the sliding groove 133 reserves more length along the direction D1 (corresponding to the rear of the display 300), and the sliding groove 133 reserves less length along the opposite direction D1 (corresponding to the front of the display 300). Thus, the carrying seat 130 and the photographing device 210 disposed thereon can slide forward by a large angle, and the user is prevented from sliding the photographing device 210 to the rear of the display 300 excessively and being unable to photograph the user in front of the display 300.

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

Fig. 7 and 8 illustrate the embodiment in which the photographing device 210 slides forward on the supporting base 130. As can be seen from fig. 7 and 8, the sliding groove 133 is set back by a greater length around the bracket 113, so that the rotary camera structure 200 can slide to a greater angle in front of the display 300.

In some embodiments, if fig. 6 is defined as a standard position of the photographing device 210 and the carrying seat 130, the photographing device 210 and the carrying seat 130 of fig. 8 slide 50 degrees in front of the display 300 relative to fig. 6, and the other end of the carrying seat 130 abuts against the bracket 113.

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

Fig. 9 and 10 illustrate the embodiment in which the photographing device 210 slides backward on the supporting base 130. As can be seen from fig. 9 and 10, since the sliding groove 133 is set forward with the bracket 113 as a center, the rotational photographing structure 200 has a smaller slidable angle toward the rear of the display 300.

In some embodiments, if fig. 6 is defined as a standard position of the photographing device 210 and the carrying seat 130, the photographing device 210 and the carrying seat 130 of fig. 10 slide 30 degrees to the rear of the display 300 relative to fig. 6, and the other end of the carrying seat 130 abuts against the bracket 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 and can be attached to the curved surface of the foot rest in a sliding manner through the spring, 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 photographic device to form a rotary photographic structure which can be fixed on a display as a video lens to be convenient for a user to adjust, and the bearing seat is provided with the photographic device to cover the mechanical structure and most components of the rotary mechanism, so that the naked body is reduced and the whole body is more beautiful.
