Detailed Embodiments

[0037] To make the objectives, technical solutions and advantages of the present invention clearer, the following will, in conjunction with the embodiments of the present invention, clearly and completely describe the technical solutions in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0038] To solve the technical problem that a camera device cannot adjust its angle with a constant focal length, the present invention provides an angle adjustment device. The angle adjustment device includes a base and a swinging member. The swinging member is slidably arranged on the base along an arc path and is used to mount the camera device base. Among them, the swinging member always rotates around the focal point of the camera device during the sliding process on the base. The following will be elaborated in detail.

[0039] The present invention provides an angle adjustment device 100, which is connected to a camera device 210 and can enable the camera device 210 to adjust its angle relative to the object to be photographed with a constant focal length. Furthermore, the light collected by the camera device 210 is perpendicular to the tangent of the arc surface of the object to be photographed, so as to achieve the best lighting effect and further achieve a better photographing effect.

[0040] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 is a schematic diagram of the mechanism of an embodiment of the angle adjustment device of the present invention; Figure 2 is Figure 1 a schematic diagram of the structure of another perspective of the angle adjustment device shown in Figure 3 is Figure 1 a schematic diagram of the structure of other perspectives of the angle adjustment device shown in . The angle adjustment device 100 includes a base 10, a swinging member 20 and an adjustment assembly 30. The swinging member 20 is arranged relative to the base 10, and the adjustment assembly 30 is connected to the base 10 and the swinging member 20. The base 10 is used to stabilize the angle adjustment device 100. The swinging member 20 mounts the camera device 210 and is used to drive the camera device 210 to rotate. The adjustment assembly 30 is used to adjust the swing of the swinging member 20 relative to the base 10 to adjust the angle of the camera device 210 relative to the base 10.

[0041] In this embodiment, the camera device 210 is a 3D camera; it can be understood that in other embodiments, according to different working conditions, the camera device 210 can also be other camera or photographic equipment, without specific limitation.

[0042] The base 10 includes a first side wall 11 and a second side wall 12 which are oppositely arranged. One of the first side wall 11 and the second side wall 12 is used to connect the swinging member 20 and assist in guiding the swinging of the swinging member 20, and the other assists in guiding the swinging of the swinging member 20. In the present embodiment, the shape of the base 10 is generally rectangular; it can be understood that in other embodiments, the base 10 can also be in other regular or irregular shapes.

[0043] The swinging member 20 includes two side plates 21 and a mounting plate 22, and both side plates 21 are connected to the mounting plate 22. The two side plates 21 are used to enable the swinging member 20 to rotate relative to the base 10, and the mounting plate 22 mounts the imaging device 210.

[0044] The two side plates 21 are respectively fixed to two opposite sides of the mounting plate 22. In the present embodiment, the two side plates 21 and the mounting plate 22 are of an integrally formed structure. The integral formation can enable a better connection stability between the two side plates 21 and the mounting plate 22, thereby improving the movement accuracy of the angle adjustment device 100 and being beneficial for use; it can be understood that in other embodiments, the two side plates 21 and the mounting plate 22 can also be of a split structure and are connected by means such as gluing, snap connection or screw connection.

[0045] The two side plates 21 are respectively arranged opposite to the first side wall 11 and the second side wall 12, and at least a part of the base 10 is accommodated between the two side plates 21, so that the two side plates 21 can swing relative to the base 10. Specifically, a sliding member 13 is provided on the first side wall 11, and an arc-shaped sliding groove 23 is formed on the side plate 21 corresponding to the first side wall 11. The sliding member 13 is slidably arranged in the sliding groove 23, and the center of the arc corresponding to the sliding groove 23 coincides with the rotation center A. Thus, the side plate 21 can slide relative to the base 10 along an arc-shaped path through the sliding groove 23, and further drive the imaging device 210 mounted on the mounting plate 22 to adjust the angle relative to the base 10. And during the rotation process, since the focus of the imaging device 210 is the rotation center A, the focal length of the imaging device 210 remains unchanged, which is beneficial for the lighting of the imaging device 210 and further beneficial for improving the shooting effect of the imaging device 210.

[0046] In the present embodiment, the two side plates 21 jointly drive the mounting plate 22 to swing, which can enhance the stability of the angle adjustment device 100 and is beneficial for the stable transmission of the angle adjustment device 100; it can be understood that in other embodiments, the number of the side plates 21 can also be set to one, and the outer side wall of the base 10 is slidably connected in the above manner, as long as it can ensure that the side plate 21 smoothly drives the mounting plate 22 to swing.

[0047] In this embodiment, the two side plates 21 are respectively arranged in sliding fit with the first side wall 11 and the second side wall 12, so as to prevent the side plates 21 from shaking between the outer side wall of the base 10, further improving the stability of the angle adjustment device 100, preventing the camera device 210 from shaking, and being beneficial to use. It can be understood that in other embodiments, according to different working conditions, the two side plates 21 and the outer side wall of the base 10 can also be arranged in other ways.

[0048] In this embodiment, the number of the sliding grooves 23 on one side plate 21 is two, namely a first sliding groove 231 and a second sliding groove 232. The first sliding groove 231 and the second sliding groove 232 are arranged at intervals, and the centers of the arcs corresponding to the first sliding groove 231 and the centers of the arcs corresponding to the second sliding groove 232 both coincide with the rotation center A. The number of the sliding members 13 on the first side wall 11 is also two, namely a first sliding member 131 and a second sliding member 132. The first sliding member 131 is slidably arranged in the first sliding groove 231, and the second sliding member 132 is slidably arranged in the second sliding groove 232. Such an arrangement can form a virtual swing "fulcrum", ensuring that the swing member 20 always rotates around the rotation center A which is the focus of the camera device 210 during the sliding process relative to the base 10. At the same time, the guiding effect on the swing member 20 is enhanced, so that the swing member 20 can slide smoothly, which is beneficial to use. It can be understood that in other embodiments, according to different working conditions, the numbers of the sliding grooves 23 and the sliding members 13 can also be set to other values, as long as the smooth swing of the swing member 20 can be ensured.

[0049] In this embodiment, the sliding grooves 23 are only arranged on one of the two side plates 21, the sliding members 13 are arranged on the outer side wall of the base 10 corresponding to the side plate 21, and the other side plate 21 is only in sliding fit with the corresponding outer side wall of the base 10, so as to avoid the situation that the sliding grooves 23 are arranged on both side plates 21 and the easy jamming caused by the movement deviation between the two side plates 21, which is beneficial to improving the reliability of the angle adjustment device 100. It can be understood that in other embodiments, according to different working conditions, the sliding grooves 23 can also be arranged on both side plates 21, as long as the smooth transmission of the angle adjustment device 100 can be ensured. Of course, in other embodiments, the sliding grooves 23 can also be arranged on the outer side wall of the base 10, and the sliding members 13 can be arranged on the side plates 21, which can also ensure that the cooperation between the sliding grooves 23 and the sliding members 13 achieves the above purpose.

[0050] In this embodiment, one sliding member 13 is correspondingly arranged for each sliding groove 23. It can be understood that in other embodiments, according to different working conditions, multiple sliding members 13 can also be correspondingly arranged for each sliding groove 23. The multiple sliding members 13 can limit the swing member 20, prevent the swing member 20 from shifting relative to the base 10, and further improve the stability of the angle adjustment device 100.

[0051] In the present embodiment, the sliding member 13 is a roller, which has advantages such as low cost and good sliding performance. The roller abuts against one side wall of the sliding groove 23 and is spaced from the other side wall of the sliding groove 23. Thus, the contact point between the sliding groove 23 and the roller is a force application point of the swing member, and the connection part between the swing member 20 and the adjusting assembly 30 is another force application point. The two force application points jointly stabilize the swing member 20, prevent the swing member 20 from deflecting, and are beneficial to the normal use of the angle adjusting device 100. It can be understood that in other embodiments, the sliding member 13 can also be other sliding elements as long as the above object can be achieved.

[0052] The horizontal position where the midpoint of the arc-shaped sliding groove 23 is located is higher than the horizontal position where the rotation center A is located, that is, the swing member 20 is perpendicular to the rotation center A. Under the action of the gravity of the swing member 20, the sliding groove 23 abuts against the sliding member 13, thereby further preventing the swing member 20 from deflecting and being beneficial to use.

[0053] The angle adjusting device 100 further includes a limiting member (not shown in the figure); a plurality of spaced-apart positioning holes 14 are formed on the outer side wall of the base 10 corresponding to the sliding track of the sliding groove 23. Thus, after the swing member 20 swings relative to the base 10 to the desired angle, the limiting member can be placed in the corresponding positioning hole 14 and abut against the edge of the sliding groove 23, thereby positioning the swing member 20 and being beneficial to the stable shooting of the imaging device 210. Among them, the specific positioning method of the limiting member for the swing member 20 can adopt clamping, snapping, screwing or adsorption and other methods, so that the limiting member locks the swing member 20, thereby ensuring good stability of the swing member 20 after the angle is adjusted and being beneficial to the use of the angle adjusting device 100.

[0054] In the present embodiment, a plurality of positioning holes 14 are provided on the first side wall 11 corresponding to the sliding track of the first sliding groove 231 and corresponding to the sliding track of the second sliding groove 232. The number of limiting members is two, and the two limiting members can be respectively placed in the positioning holes 14 corresponding to the first sliding groove 231 and the positioning holes 14 corresponding to the second sliding groove 232, thereby jointly stabilizing the swing member 20, further improving the reliability of the angle adjusting device 100 and being beneficial to use. It can be understood that in other embodiments, according to the different numbers of the sliding grooves 23, the number of the limiting members can also be set to other values as long as the limiting member can stabilize the swing member 20 to the desired angle.

[0055] In the present embodiment, the base 10 is provided with an angle mark (not shown in the figure) corresponding to the sliding track of the sliding groove 23. The angle mark is used to assist the swing member 20 to adjust the angle relative to the base 10, so that the swing member 20 can be quickly adjusted to the desired angle and is convenient to use. It can be understood that in other embodiments, according to different working conditions, when the swing member 20 can quickly and accurately adjust the angle, the angle mark can also be omitted.

[0056] The adjusting assembly 30 includes a guide member 31 and an adjusting member 32. The guide member 31 is disposed on the base 10. The adjusting member 32 connects the guide member 31 and the swing member 20. The guide member 31 is used to adjust the position of the adjusting member 32. The adjusting member 32 is used to adjust the swing member 20 to swing relative to the base 10.

[0057] The base 10 is provided with a slide rail 15, and the slide rail 15 and the first slide groove 231 respectively have an angle between the projections of the plane parallel to the side plate 21. The guide member 31 is slidably arranged on the slide rail 15, one end of the adjustment member 32 is rotatably connected to the guide member 31, and the other end of the adjustment member 32 is connected to the side plate 21. The adjustment member 32 can drive the side plate 21 to move by axial movement, and during the movement of the side plate 21, the adjustment member 32 can move relative to the base 10 through the guide member 31 to adapt to the position change of the non-axial offset of the adjustment member 32 caused by the arc sliding of the side plate 21, and further enable the mounting plate 22 to swing relative to the base 10 to adjust the angle of the mounting plate 22 relative to the base 10.

[0058] In this embodiment, the slide rail 15 extends in the horizontal direction; it can be understood that in other embodiments, the slide rail 15 may also extend in other directions according to the size and shape of each component.

[0059] In this embodiment, the adjusting member 32 is arranged on the side of the slide groove 23 away from the rotation center A, so that the adjusting member 32 can adjust the angle of the mounting plate 22 relative to the base 10 by pulling the side plate 21, thereby ensuring the smooth transmission of the angle adjustment device 100; it can be understood that in other embodiments, according to different working conditions, the adjusting member 32 can also be set at other positions, as long as the above purpose can be achieved.

[0060] A rotating member 33 is also provided between the guide member 31 and the adjusting member 32, and the rotating member 33 is rotatably connected to the guide member 31; the adjusting member 32 includes an adjusting rod 321, one end of which is clamped on the rotating member 33 and can rotate relative to the rotating member 33. The setting of the rotating member 33 facilitates the installation of the adjusting member 32 on the guide member 31, and when the adjusting member 32 rotates to adjust the angle of the swinging member 20, the adjusting rod 321 can adjust the angle relative to the guide member 31 through the rotating member 33, and can adjust the position relative to the base 10 through the guide member 31, which is beneficial for the adjusting member 32 to smoothly drive the swinging member 20 and improve the reliability of the angle adjustment device 100.

[0061] The adjusting member 32 also includes an adjusting block 322, which is fixedly connected to the side plate 21. The other end of the adjusting rod 321 is screwed to the adjusting block 322, so that the adjusting rod 321 can rotate to drive the adjusting block 322 to move closer to or away from the guide member 31, and further the adjusting block 322 drives the swinging member 20 to swing relative to the base 10, thereby achieving corresponding angle adjustment.

[0062] In this embodiment, the adjusting block 322 is provided with a threaded hole, and the adjusting rod 321 is screwed into the threaded hole by threads. Specifically, the threads are fine threads. Using fine threads can finely adjust the movement of the adjusting block 322, and further enable the adjusting rod 321 to finely drive the swinging member 20 to swing through the adjusting block 322. It can be understood that in other embodiments, according to different working conditions, the adjusting rod 321 and the adjusting block 322 can also be screwed together by other threads as long as the above object can be achieved.

[0063] It is worth noting that the guiding member 31 can limit the axial movement of the adjusting rod 321, so that the adjusting rod 321 uses the guiding member 31 as a force application point to assist in driving the swinging member 20 to swing, preventing the angle adjusting device 100 from malfunctioning due to the axial movement of the adjusting rod 321. In this embodiment, the guiding member 31 axially limits the adjusting rod 321 by clamping the adjusting rod 321 through the rotating member 33. It can be understood that in other embodiments, the guiding member 31 can also axially limit the adjusting rod 321 in other ways, directly or indirectly.

[0064] In this embodiment, the adjusting assembly 30 further includes a driving member (not shown in the figure). The output end of the driving member can drive the adjusting member 32 to rotate, and then the adjusting member 32 drives the mounting plate 22 to rotate relative to the base 10 through the side plate 21, so as to realize the automatic swinging of the swinging member 20 relative to the base 10, and then automatically adjust the rotation angle of the imaging device 210. It can be understood that in other embodiments, according to the corresponding working conditions, the adjusting member 32 can also be manually adjusted to rotate.

[0065] In this embodiment, the driving member is selected as a motor, and the motor has the advantages of convenient material acquisition and low price. It can be understood that in other embodiments, the driving member can also be selected as other types of driving sources as long as it can drive the adjusting member 32 to rotate automatically.

[0066] It is worth noting that the motor can be connected to a controller (not shown in the figure), and the controller can control the motor to perform corresponding angle adjustments according to the preset parameters, so as to achieve the purpose of automatically adjusting the angle of the swinging member 20 as described above.

[0067] For the angle adjusting device provided by the present invention, the swinging member is used to mount the imaging device, and it is slidably arranged on the base along an arc path, and the swinging member always rotates around the focus of the imaging device during the sliding process on the base, so that the imaging device can adjust the angle with a constant focal length, ensuring that the imaging device can achieve a better shooting effect. Moreover, the angle adjusting device has a simple structure and occupies a small space, and can be applied to most working conditions, which is conducive to use.

[0068] Please refer to Figure 4 , Figure 4The figure is a schematic structural diagram of an embodiment of the camera system of the present invention. The present invention also provides a camera system 200, including a camera device 210 and the above-mentioned angle adjustment device 100. The camera device 210 is disposed on the swing member 20. The focal point of the camera device 210 coincides with the rotation center A. The swing member 20 can drive the camera device 210 to rotate relative to the base 10 around the focal point.

[0069] The camera system provided by the present invention has a good shooting effect and broad application prospects by setting the above-mentioned angle adjustment device 100.
