[0001] This utility model relates to the field of artificial intelligence technology, and in particular to a data acquisition device. Background Technology

[0002] Artificial intelligence data acquisition refers to the process of collecting data from various sources for training, testing, and optimizing artificial intelligence models. This data can be in various forms such as text, images, and voice, and originates from the Internet, laboratories, sensors, etc. Data acquisition is the foundation for building artificial intelligence models, and its quality and diversity directly affect the model's performance. Data acquisition often requires the use of acquisition devices to complete the acquisition work. Existing acquisition devices are mostly fixed installations, which cannot adjust the acquisition angle and are not conducive to adjusting the acquisition range, thus affecting the acquisition effect and flexibility. Utility Model Content

[0003] The purpose of this invention is to propose a data acquisition device that solves the technical problem in the prior art where the acquisition device is fixedly installed, which is not conducive to adjusting the acquisition range and affects the acquisition effect and flexibility.

[0005] This utility model provides a data acquisition device, including a protective box and an acquisition component. A lifting drive mechanism is installed inside the protective box, and the acquisition component is located at the output end of the lifting drive mechanism. The lifting drive mechanism drives the acquisition component to move up and down, extending or retracting it from the protective box. The acquisition component includes:

[0006] A support frame is disposed at the output end of the lifting drive mechanism;

[0007] A load-bearing ring, which is rotatably mounted on the support frame around a horizontal axis;

[0008] A flipping component is rotatably disposed within the support ring and can rotate around the center of the support ring. A data acquisition device is movably disposed on the flipping component.

[0009] The data acquisition device features an upgraded drive mechanism within a protective enclosure. This mechanism drives the acquisition component to move up and down, extending or retracting it from the enclosure. The acquisition component includes a support frame, a support ring, a tilting assembly, and a data acquisition unit. The support frame is located at the output end of the lifting drive mechanism. The support ring rotates along a horizontal axis on the support frame. The tilting assembly rotates within the support ring and can rotate around its center. The data acquisition unit is movably mounted on the tilting assembly. The rotation of the support ring around the horizontal axis drives the tilting assembly and the data acquisition unit to rotate around the horizontal axis. The tilting assembly rotates around the center of the support ring, causing the data acquisition unit to rotate around the center of the support ring. The movable mounting of the data acquisition unit on the tilting assembly allows for adjustment of its height, angle, and position, thereby adjusting the acquisition range and improving the acquisition effect and flexibility.

[0010] As a preferred embodiment of the aforementioned data acquisition device, the acquisition component further includes:

[0011] A first rotation drive mechanism is disposed on the support frame, and the output end of the first rotation drive mechanism is connected to the bearing ring to drive the bearing to rotate around the horizontal axis.

[0013] As a preferred embodiment of the aforementioned data acquisition device, the acquisition component further includes:

[0014] A second rotation drive mechanism is disposed on the bearing ring, and the output end of the second rotation drive mechanism is connected to the flipping assembly for driving the flipping assembly to rotate around the center of the bearing ring.

The rotation of the driven gear ring drives the flipping component to rotate, thereby realizing the rotation of the data acquisition device on the flipping component around the center of the bearing ring.

[0021] As a preferred embodiment of the aforementioned data acquisition device, a movable ring is rotatably provided on the inner wall of the bearing ring, and the center of the movable ring coincides with that of the bearing ring.

The bidirectional lead screw rotates to drive the two sets of bidirectional threaded rods and the data acquisition devices to move closer or further apart from each other.

[0028] By rotating the bidirectional lead screw, two sets of bidirectional threaded rods are driven to move closer or further apart, thereby driving two sets of data acquisition units to move closer or further apart. This flipping component has a simple structure and is easy to manufacture.

[0029] As a preferred embodiment of the aforementioned data acquisition device, the flip bracket is provided with a guide hole, the guide hole extends along the length direction of the bidirectional threaded rod, the bidirectional threaded rod passes through the guide hole and moves along the extension direction of the guide hole.

[0050] like Figures 1-3 As shown, this embodiment provides a data acquisition device, including a protective box 1 and an acquisition component. A lifting drive mechanism 2 is installed inside the protective box 1. The acquisition component is located at the output end of the lifting drive mechanism 2. The lifting drive mechanism 2 drives the acquisition component to move up and down, extending or retracting from the protective box 1. The acquisition component includes a support frame 3, a bearing ring 4, a flipping component 5, and a data acquisition device 6. The support frame 3 is located at the output end of the lifting drive mechanism 2; the bearing ring 4 is rotatably mounted on the support frame 3 about a horizontal axis; the flipping component 5 is rotatably mounted inside the bearing ring 4 and can rotate about the center of the bearing ring 4; the data acquisition device 6 is movably mounted on the flipping component 5.

[0051] The data acquisition device rotates the support ring 4 around the horizontal axis, thereby driving the flipping component 5 and the data acquisition device 6 to rotate around the horizontal axis. The flipping component 5 rotates around the center of the support ring 4, causing the data acquisition device 6 to rotate around the center of the support ring 4. The data acquisition device 6 is movably mounted on the flipping component 5, thereby realizing the adjustment of the height, angle and position of the data acquisition device 6 to adjust the acquisition range and improve the acquisition effect and flexibility.

[0052] Specifically, such as Figure 2As shown, the lifting drive mechanism 2 includes a lifting frame 21, a lifting motor 23, and a lifting threaded sleeve 24. Two sets of lifting frames 21 are spaced apart. In this embodiment, the two sets of lifting frames 21 are symmetrically arranged inside the protective box 1. Each set of lifting frames 21 has a lifting screw 22 rotatably installed inside, and the lifting screw 22 extends vertically. A lifting motor 23 is installed on the top of each set of lifting frames 21. The output end of the lifting motor 23 is rotatably connected to the lifting screw 22, and the corresponding lifting screw 22 is driven to rotate by the lifting motor 23. Each set of lifting screw 22 is fitted with a set of lifting threaded sleeves 24. The lifting threaded sleeves 24 are threadedly connected to the lifting screw 22 through an L-shaped bracket 10. The support frame 3 is connected between the two sets of lifting threaded sleeves 24. When the lifting screw 22 rotates, the lifting threaded sleeves 24 and the support frame 3 achieve lifting and lowering movement. The above-mentioned lifting drive mechanism 2 has a simple structure and can easily drive the lifting and lowering of the support frame 3.

[0053] like Figure 2 and Figure 3 As shown, the support frame 3 has a semi-circular ring structure, and both sides of the support frame 3 are connected to the lifting threaded sleeve 24 through a set of L-shaped brackets 10. The bearing ring 4 is rotatably disposed inside the support frame 3 and is rotatably connected to both ends of the support frame 3. The support frame 3 has a semi-circular ring structure, which can support the bearing ring 4, and its shape is compatible with the bearing ring 4, making it aesthetically pleasing.

[0054] Optionally, such as Figure 1 As shown, the acquisition assembly also includes a first rotation drive mechanism 7, which is mounted on the support frame 3. The output end of the first rotation drive mechanism 7 is connected to the bearing ring 4 for transmission, so as to drive the bearing ring 4 to rotate around the horizontal axis. The first rotation drive mechanism 7 can drive the bearing ring 4 to rotate around the horizontal axis, so as to realize the adjustment of the angle of the data acquisition unit 6 around the horizontal axis.

[0055] Specifically, such as Figure 3 As shown, the first rotation drive mechanism 7 includes an adjustment motor 71. An adjustment motor 71 is mounted at both ends of the support frame 3, and a drive shaft 72 is mounted at the output end of each adjustment motor 71. A bearing ring 4 is provided between the two sets of drive shafts 72, and the bearing ring 4 is connected to the drive shafts 72. The adjustment motor 71 drives the drive shafts 72 to rotate, which in turn drives the bearing ring 4 to rotate, thereby adjusting the angle.

[0056] Optionally, such as Figure 1 As shown, the acquisition component also includes a second rotation drive mechanism 8, which is disposed on the support ring 4. The output end of the second rotation drive mechanism 8 is connected to the flipping component 5 for transmission, so as to drive the flipping component 5 to rotate around the center of the support ring 4. The second rotation drive mechanism 8 can drive the flipping component 5 to rotate around the center of the support ring 4, thereby realizing the adjustment of the angle of the data acquisition unit 6 around the center of the support ring 4.

[0057] like Figure 4 As shown, the second rotation drive mechanism 8 includes a rotation drive motor 81, a driving gear 82, and a driven gear ring 83. The rotation drive motor 81 is mounted on the bearing ring 4. A linkage shaft 84 is installed at the output end of the rotation drive motor 81, and the driving gear 82 is sleeved on the linkage shaft 84. The rotation drive motor 81 drives the driving gear 82 to rotate. The driven gear ring 83 is rotatably mounted on the bearing ring 4. The outer circumference of the driven gear ring 83 is provided with meshing teeth. The driving gear 82 meshes with the driven gear ring 83. The flipping component 5 is disposed inside the driven gear ring 83 and rotates synchronously with the driven gear ring 83. The second rotation drive mechanism 8 drives the driving gear 82 to rotate through the rotation drive motor 81, which in turn drives the driven gear ring 83, which meshes with the driving gear 82, to rotate. The rotation of the driven gear ring 83 drives the flipping component 5 to rotate, thereby realizing the rotation of the data acquisition device 6 on the flipping component 5 around the center of the bearing ring 4.

[0058] Optionally, a movable ring 9 is rotatably provided on the inner wall of the bearing ring 4. The movable ring 9 is slidably connected to the inner wall of the bearing ring 4, and the center of the movable ring 9 coincides with that of the bearing ring 4. A driven gear ring 83 is connected to one side of the movable ring 9, and a flipping assembly 5 is disposed inside the movable ring 9 and connected to it. The flipping assembly 5 is connected to the driven gear ring 83 through the movable ring 9, so that when the driven gear ring 83 rotates, the flipping assembly 5 is driven to rotate through the movable ring 9. Optionally, the flipping assembly 5 is arranged radially along the movable ring 9.

[0059] In this embodiment, the flipping component 5 includes two sets of data collectors 6. The two sets of data collectors 6 are movably arranged on the flipping component 5 along the length direction of the flipping component 5 so that they can move closer to or further away from each other, thereby adjusting the range and position of data collection and making it more adaptable.

[0060] Specifically, such as Figure 5 As shown, the flipping assembly 5 includes a flipping bracket 51 and a bidirectional lead screw 52. The flipping bracket 51 is rotatably mounted within the bearing ring 4. The bidirectional lead screw 52 is rotatably mounted on the flipping bracket 51 and extends along the length of the flipping bracket 51. The bidirectional lead screw 52 is connected to a drive motor 54, which drives the bidirectional lead screw 52 to rotate. The bidirectional lead screw 52 is threadedly connected to two sets of bidirectional threaded rods 53. Each set of bidirectional threaded rods 53 is equipped with a set of data acquisition devices 6. The rotation of the bidirectional lead screw 52 causes the two sets of bidirectional threaded rods 53 to move closer or further apart, thereby causing the two sets of data acquisition devices 6 to move closer or further apart, thus adjusting the data acquisition range. This flipping assembly 5 has a simple structure and is easy to manufacture.

[0061] Optionally, the flip bracket 51 is provided with a guide hole 511 (see Figure 4The guide hole 511 extends along the length of the bidirectional lead screw 52, ​​and the bidirectional threaded rod 53 passes through the guide hole 511 and moves along the extension direction of the guide hole 511. The guide hole 511 guides the movement of the bidirectional threaded rod 53 and prevents the bidirectional threaded rod 53 from rotating with the bidirectional lead screw 52.

[0062] In this embodiment, the data collector 6 is an optical camera capable of acquiring image data. An AI chip is installed inside the optical camera, which performs artificial intelligence data acquisition on the object being collected. In other embodiments, the data collector 6 is not limited to an optical camera; it can be any other data acquisition device.

[0063] Working principle: The lifting motor 23 drives the lifting screw 22 to move the lifting threaded sleeve 24 upward. The lifting threaded sleeve 24, through the L-shaped bracket 10, drives the support frame 3, the bearing ring 4, the movable ring 9, the flipping assembly 5, and the optical camera upward, thus moving the optical camera to the outside of the protective box 1. The optical camera is equipped with an AI chip, which performs artificial intelligence data acquisition on the object being collected. The adjustment motor 72 drives the bearing ring 4 to rotate through the drive shaft 71. The bearing ring 4 drives the movable ring 9, the flipping assembly 5, and the optical camera to rotate, thereby adjusting the acquisition angle of the optical camera. When it is necessary to adjust the acquisition range of the optical camera, the drive motor 54 drives the bidirectional screw 52 to rotate. Two sets of bidirectional threaded rods 53 are driven to move away from each other, and each set of optical cameras is driven to move away from each other, thereby adjusting the distance between the two sets of optical cameras and their acquisition range. The rotation drive motor 81 drives the drive gear 82 to rotate through the linkage shaft 84. The drive gear 82 drives the movable ring 9 to rotate inside the bearing ring 4 through the driven gear ring 83. The bearing ring 4 drives the flipping component 5 and the optical cameras to rotate inside the bearing ring 4, so that the optical cameras can perform a panoramic acquisition of the object. After the acquisition is completed, all the above operations are reset, and the whole device is stored back inside the protective box 1 for storage and protection, thus completing the use of the new artificial intelligence data acquisition device.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
