Description

Technical Field

[0001] The present invention belongs to the technical field of data scanning, and in particular relates to a wearable three-dimensional scanner auxiliary device. Background Art

[0002] Compared to traditional station-mounted 3D scanners, handheld 3D laser scanners are lightweight, portable, simple to operate, and fast. Traditional station-mounted 3D scanners require scanning at each station, requiring time to wait for scanning and station relocation. Handheld 3D laser scanners, on the other hand, can scan while walking, collecting point cloud data on the go, offering greater flexibility. Common applications include: spatial pipeline corridors, cultural relic protection, architectural surveying, and cadastral mapping.

[0003] Handheld 3D laser scanners offer numerous advantages, but they require operators to hold the instrument and view real-time scanning results on their mobile phones. This can cause elbow discomfort in large, wide-area scanning environments.

[0004] Patent number CN216243153U specifically discloses a wearable arm-lifting and labor-saving bracket for 3D modeling data scanning. This utility model secures the 3D instrument by wearing it, shifting the weight of the scanner from the user's hands to their body, freeing the user's hands and reducing the operational burden. However, the wearable arm-lifting and labor-saving bracket has a simple structure, making it impossible to adjust the position of the device at will, and unable to adapt to the needs of 3D scanning in different scenarios. Moreover, the device for securing the instrument is not compatible with the specifications of most 3D scanning instruments. The present invention provides a solution to this technical problem.

Rotation grooves are respectively provided on both sides of the first movable sleeve 12, and the opening and closing frame 15b is rotatably connected to the movable sleeve through a vertically arranged rotation shaft in the rotation groove. The rotation groove limits the opening and closing frame 15b, so that the opening and closing frame 15b is limited to rotate within a certain range, thereby reducing the tediousness of repeatedly adjusting the angle of the opening and closing frame 15b during use.

[0042] The upper part of the second movable sleeve 14 is fixedly connected to a fixed base 16, which is annular with a slot in the middle. When in use, put down the lifting frame 15a, open the opening and closing frame 15b, put the instrument on the fixed base 16, and then close the fixing frame 15 to fix the instrument.

[0043] See also Figure 1 The lower part of the second movable sleeve 14 is sleeved with a rotating sleeve 17 that can rotate on the movable sleeve. The second movable sleeve 14 is provided with limit rings on both sides of the rotating sleeve 17 to prevent the vertical movement of the rotating sleeve 17. The rotating sleeve 17 is also connected to the mobile phone holder 6. A long rotating shaft seat 17c is provided on the back of the mobile phone holder 6. The rotating sleeve 17 and the long rotating shaft seat 17c are rotatably connected by providing a long rotating shaft 17b. The overall structure of the rotating sleeve and the long rotating shaft enables the mobile phone holder 6 to rotate in the horizontal direction and adjust the elevation angle in the vertical direction.

[0044] See also Figure 6 The mobile phone holder 6 adopts a spring clamping structure. The mobile phone holder 6 includes a plywood 61 and a mounting plate 62. Several slide grooves 63 are provided on the left and right sides of the front of the mounting plate 62. The back of the plywood 61 is fixedly connected with a sliding block 64 that slides on the inner wall of the slide groove 63. A spring 65 is provided between the sliding block 64 and the inner wall of the slide groove 63. Under the action of the spring force, a large clamping force is generated between the two plywoods 61 of the mobile phone holder 6. A rubber pad 66 is fixedly provided on the surface of the plywood 61 to increase the friction between the mobile phone and the plywood 61. The two sides of the sliding block 64 are fixedly connected with a limiting block 64a, and the mounting plate 62 is provided with a limiting groove 64b at the position corresponding to the limiting block 64a, so that the sliding block 64 can be stable in the slide groove 63 when moving.

[0045] See also Figure 7 In order to make the connection between the support arm 2 and the first connecting member 5 more stable during use, the present invention provides the following connection method, but the connection method between the support arm 2 and the first connecting member 5 is not limited to this. All connection methods that can achieve a rotatable connection between the support arm 2 and the first connecting member 5 can be used;

[0046] The first connecting member 5 is rotatably connected to the support arm 2 in the vertical direction through a horizontally arranged rotation locking device 51, and can be locked and fixed after rotation. The rotation locking device 51 includes: a locking knob 51a, and a screw 52b passing through the end of the support arm 2 and the first connecting member 5, and the other end is threadedly connected to a nut 52c. When in use, loosen the locking knob 51a, adjust the rotation angle of the fixer 1, and then tighten the locking knob 51a to fix it.

[0047] The present invention is used as follows: the scanner puts on the adjustable vest and adjusts it to the appropriate tightness. The scanner then inserts the latch plate into the latch, adjusts the adapter assembly 4 and the holder 1 to the desired angle, and then adjusts the connecting components of the holder 1 to adjust the holder 1 to the appropriate elevation angle. The scanner then opens the fixing frame 15, lowers the lifting frame 15a, places the 3D scanner on the lifting frame 15a, and closes the fixing frame 15 to secure the 3D scanner. The scanner then adjusts the first movable sleeve 12 and the second movable sleeve 14 to the appropriate height. Scanning can then begin. If the angle and height need to be adjusted during operation, the connected components can be adjusted sequentially, which is very convenient and labor-saving.
