[0055] like Figure 1 As shown, this application embodiment provides an angle adjustment device, which includes a base 10, a first support frame 20, a second support frame 30, and a carrier 40;

[0056] The first support frame 20 is rotatably mounted on the base 10 about the first direction as an axis;

[0057] The second support frame 30 is rotatably mounted on the first support frame 20 about the second direction as an axis;

[0058] The carrier 40 is rotatably mounted on the second support frame 30 about a third direction axis. The carrier 40 is used to carry the product to be tested.

[0059] The angle adjustment device provided in this application embodiment allows the product under test to rotate around a third direction as an axis by rotating the carrier 40, thereby achieving angle adjustment in one dimension. By rotating the second support frame 30, the product under test can rotate around a second direction as an axis, thereby achieving angle adjustment in two dimensions. By rotating the first support frame 20, the product under test can rotate around a first direction as an axis, achieving angle adjustment in three dimensions. This greatly improves the convenience of angle adjustment and can meet the testing needs of the product under test at any angle.

[0060] It should be noted that the first direction mentioned above is the Z-axis, and the first support frame 20 is rotatably mounted on the base 10 about the first direction as its axis, that is, the first support frame 20 rotates around the Z-axis; the second direction is the Z-axis, and the second support frame 30 is rotatably mounted on the first support frame 20 about the second direction, that is, the second support frame 30 rotates around the Z-axis; the third direction is the Y-axis, and the carrier 40 is rotatably mounted on the second support frame 30 about the third direction as its axis, that is, the carrier 40 rotates around the Y-axis. In this way, the product under test located on the carrier 40 can rotate along the X-axis, Y-axis, and Z-axis, thereby achieving arbitrary angle adjustment to meet the testing requirements of the product under test.

[0061] In the application, the products to be tested include, but are not limited to, cameras, smartphones, tablets, smartwatches, digital cameras, gyroscopes, etc.

[0062] In some embodiments, such as Figure 3 As shown, the angle adjustment device also includes a first drive assembly 50, which drives the first support frame 20, the second support frame 30, the carrier 40, and the product to be tested located on the carrier 40 to rotate around a first direction as an axis. In application, the first drive assembly 50 is a direct drive motor (also known as a DD motor), which is an electric motor that directly converts electrical energy into mechanical energy. It does not use a traditional reduction gear system but directly generates the required torque and speed through the motor itself. The main features of the DD motor are high efficiency, precision, low noise, and compact design, making it very suitable for applications requiring high-precision positioning and stability.

[0063] In some embodiments, such as Figure 2 As shown, the first support frame 20 includes a first support plate 21 and two first connecting plates 22;

[0064] The middle part of the first support plate 21 is rotatably connected to the base 10;

[0065] Two first connecting plates 22 are respectively disposed at both ends of the support plate, and the first connecting plates 22 are disposed along the first direction;

[0066] The two ends of the second support frame 30 are rotatably connected to the ends of the two first connecting plates 22 that are away from the support plate.

[0067] This configuration increases the degree of freedom of movement. Since the middle part of the first support plate 21 is rotatably connected to the base 10, the entire first support frame 20 can rotate around the central axis of the base 10, which provides the device with the first degree of rotational freedom.

[0068] The rotatable connection between the second support frame 30 and the first connecting plate 22 allows the second support frame 30 to swing relative to the first support frame 20 in a plane perpendicular to the first direction, providing a second rotational degree of freedom. This increases structural flexibility; the multi-joint design enables the entire system to achieve complex multi-dimensional motion, suitable for applications requiring flexible adjustment of angles and positions (i.e., testing applications for electronic products). Through reasonable layout and design, a large range of motion can be achieved without increasing the overall volume, avoiding interference between mechanical components. Each rotational connection point can be equipped with a high-precision encoder or sensor for real-time monitoring and feedback of position information, thereby achieving precise control of motion.

[0069] In some embodiments, such as Figure 2 and Figure 3 As shown, a protective shell 26 is also provided on the side of the first support plate 21 away from the base 10. The protective shell 26 can cover the connection and mating part between the first support plate 21 and the first drive assembly 50, providing physical protection and preventing external dust and impurities from entering the rotating connection.

[0070] In some embodiments, such as Figure 2 and Figure 3 As shown, a first fixing plate is also provided at the connection between the first support plate 21 and the first connecting plate 22. In application, four first fixing plates are provided, which respectively fix the four connection corners of the first support plate 21 and the two first connecting plates 22. In this way, the connection stability between the first support plate 21 and the first connecting plate 22 is improved, which can effectively improve the overall stability of the first support frame 20.

[0071] In some embodiments, such as Figure 2 and Figure 3 As shown, the two first connecting plates 22, positioned close to each other, form a receiving space on the support plate. This space is used to install the second support frame 30 and the carrier 40. This layout results in a more rational structure and optimizes the spatial arrangement. It allows for a larger range of motion within a limited space, making the entire system more compact, reducing unnecessary material usage, and lowering manufacturing costs.

[0072] In some embodiments, such as Figures 2 to 4 As shown, the second support frame 30 includes two second connecting plates 32 and a second support plate 31:

[0073] The two second connecting plates 32 are rotatably connected to the two first connecting plates 22 respectively;

[0074] The second support plate 31 is located above the base 10, and its two ends are connected to the two second connecting plates 32 respectively.

[0075] The carrier 40 is rotatably positioned in the middle of the second support plate 31. This configuration allows for multi-axis rotation, enabling complex spatial movements and making it suitable for applications requiring high flexibility, thus meeting the testing needs of the product under test.

[0076] In some embodiments, such as Figure 5 and Figure 6 As shown, a second fixing plate is also provided at the connection between the second support plate 31 and the second connecting plate 32. In application, four second fixing plates are provided, which are respectively fixed at the four connection corners of the second support plate 31 and the two second connecting plates 32. This helps to improve the connection stability between the second support plate 31 and the second connecting plate 32, and can effectively improve the overall stability of the second support frame 30.

[0077] In application, the overall configuration of the second support frame 30 is the same as that of the first support frame 20. The second support frame 30 is a scaled-down version of the first support frame 20. This layout results in a compact structure and high space utilization.

[0078] In some embodiments, such as Figure 4 As shown, the angle adjustment device also includes a second drive assembly 60. The second drive assembly 60 is used to drive the second support frame 30, the carrier 40 and the product to be tested located on the carrier 40 to rotate about a second direction as an axis.

[0079] In some embodiments, such as Figure 4 As shown, the angle adjustment device also includes a second drive assembly 60, which includes a first rotary table 61 and a first drive motor 62.

[0080] The first rotary table 61 includes a fixed end and a rotating end. The fixed end is connected to a first connecting plate 22, and the rotating end is connected to a second connecting plate 32.

[0081] The first drive motor 62 is installed on the side of the first connecting plate 22 away from the second connecting plate 32, and the output end of the first drive motor 62 is connected to the rotating end.

[0082] With this configuration, the first drive motor 62, due to its large footprint, is positioned on the side away from the second support frame 30 to avoid mechanical interference during movement. The first rotary table 61 is a hollow rotary platform, and the first drive motor 62 is a servo motor. Servo motors have high torque and precise control, meeting the testing requirements at any angle.

[0083] In some embodiments, such as Figure 2 and Figure 3 As shown, a protective box 24 is provided on the side of the first connecting plate 22 away from the second support frame 30. The protective box 24 provides good physical protection for the second drive assembly 60, preventing the external environment from affecting the first drive motor 62 located inside the protective box 24. In application, multiple heat dissipation holes 240 are also provided around the protective box 24, which helps to dissipate heat from the first drive motor 62 in a timely manner, ensuring that the first drive motor 62 can work normally.

[0084] In some embodiments, two sets of second drive components 60 are provided, with the two sets of second drive components 60 corresponding to the two first connecting plates 22. The two first drive motors 62 drive the two first rotary tables 61 to rotate, thereby causing both ends of the second support frame 30 to rotate simultaneously. This allows for more powerful and faster driving, and the fact that they are located on both sides of the two first connecting plates 22 in the same manner helps to improve the stability of the overall device.

[0085] In some embodiments, such as Figure 4 As shown, a set of second drive components 60 is provided, and another first connecting plate 22 is provided with a rotating shaft 23. The other end of the rotating shaft 23 is rotatably connected to another second connecting plate 32. That is, the second drive components 60 are used for driving, and the rotating shaft 23 enables the other end of the second support frame 30 to rotate accordingly. This arrangement can effectively reduce costs and further simplify the overall structure of the device.

[0086] In some embodiments, such as Figure 4 and Figure 6 As shown, a weight reduction hole 220 is provided on the first connecting plate 22 where the first drive motor 62 is located, which can effectively reduce the weight on the side where the first drive motor 62 is located. A counterweight block 221 is provided on the other first connecting plate 22 where the rotating shaft 23 is located. This can keep the weight of the two ends of the first support frame 20 basically equal, making the rotation smoother and also improving the service life of the device.

[0087] In some embodiments, such as Figures 3 to 6 As shown, the angle adjustment device also includes a third drive assembly 70, which is used to drive the carrier 40 and the product under test located on the carrier 40 to rotate about a third direction as an axis.

[0088] In some embodiments, the second support plate 31 is provided with a mounting hole 310 in the middle, and the angle adjustment device further includes a third drive assembly 70, which includes a second rotary table 71 and a second drive motor 72.

[0089] The second rotary table 71 is installed in the mounting hole 310, and one end of the second rotary table 71 is connected to the carrier 40.

[0090] The second drive motor 72 is installed on the side of the second support plate 31 away from the carrier 40. The second drive motor 72 is connected to the other end of the second rotary table 71. The second drive motor 72 is used to drive the second rotary table 71 to rotate around a third axis, thereby rotating the carrier 40 and the product to be tested. The second rotary table 71 is a hollow rotary platform, and the second drive motor 72 is a servo motor. The servo motor has high torque and precise control, which can meet the testing requirements of any angle.

[0091] In application, the above settings enable omnidirectional motion and independent three-axis control: through the first axis (between the base 10 and the first support plate 21), the second axis (between the first connecting plate 22 and the second connecting plate 32), and the third axis (rotation between the second support plate 31 and the carrier 40), the system can achieve three independent rotational degrees of freedom. This allows the product under test to be adjusted in all directions in space, suitable for applications requiring multi-angle detection, imaging, or operation. Independent control of multiple axes allows users to precisely position the posture of the product under test, ensuring that each test angle accurately reaches the expected position.

[0092] In some embodiments, the first rotary table 61 and the second rotary table 71 are equipped with high-precision encoders or angle sensors, which can provide real-time feedback of the rotation angle, ensuring highly accurate rotation in the third direction. The second rotary table 71 is mounted in the middle of the second support plate 31, forming a stable fulcrum, reducing swaying and errors during rotation, and improving the overall system stability. The symmetrical design of the second rotary table 71 in the middle of the second support plate 31 helps maintain the stability of the system's center of gravity, reduces eccentric torque during rotation, and improves load capacity. The second drive motor 72 is mounted on the side of the second support plate 31 away from the carrier 40, avoiding direct action of the motor on the carrier, reducing additional weight and inertia, and further improving the system's balance and response speed. Integrating the second rotary table 71 into the mounting hole 310 of the second support plate 31 saves space and makes the entire system more compact. If maintenance or replacement of the second drive motor 72 or the second rotary table 71 is required, it can be operated directly from the back of the second support plate 31 without disassembling other components, simplifying the maintenance process. For convenient testing, the control system allows for easy adjustment of the angles of the carrier 40 and the product under test, providing significant convenience, especially in multi-angle photography, video recording, or complex testing scenarios. Particularly in camera equipment, this design enables smooth multi-angle shooting, enhancing the user's visual experience.

[0093] In some embodiments, such as Figure 6As shown, the carrier 40 is detachably mounted in the middle of the second support frame 30. By replacing different product carriers 40, different types of electronic products can be tested at different angles. In application, the detachable mounting methods include, but are not limited to, snap-fit, screw fixing, and magnetic attraction.

Although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
