Specific implementation

[0022] In order to make the technical means, the creation feature, the purpose and the effect of the utility model easy to understand, the following will be further described in the embodiment and the drawing, but the following embodiment is only the preferred embodiment of the utility model, and is not all. Based on the embodiment in the implementation, the other embodiments obtained by the person skilled in the art without making creative labor all belong to the protection scope of the utility model.

[0023] The specific embodiments of the utility model will be described below in conjunction with the drawings. Specific embodiment one:

[0025] Reference Figures 1-5The gimbal control device for laser scanner comprises a gimbal placing frame 1 and a placing box 13. The gimbal placing frame 1 is L-shaped, and a permanent magnet 9 is arranged at the bottom end of the gimbal placing frame 1. Limiting blocks 4 are embedded on the two sides of the front face of the gimbal placing frame 1. A horizontal sliding groove 3 is formed on the top of the front face of the gimbal placing frame 1. A driving motor set 2 is arranged on one side of the horizontal sliding groove 3. A driving shaft 5 is connected to one end of the driving motor set 2. A sliding plate 6 is threadedly connected to the driving shaft 5. The sliding plate 6 is slidably connected to the horizontal sliding groove 3. An electromagnetic column 7 is arranged in the middle of the sliding plate 6. A rotating ring layer 14 is embedded on the outer surface of the electromagnetic column 7. A bearing ring 15 is arranged on the bottom of the outer surface of the electromagnetic column 7 close to the rotating ring layer 14. A rotating motor 10 is arranged on one side of the top of the sliding plate 6. A motor shaft 11 is connected to the bottom end of the rotating motor 10. A driving gear 12 is connected to the middle of the motor shaft 11. The driving gear 12 and the rotating ring layer 14 are meshed and matched with each other. The driving gear 12 and the rotating ring layer 14 are externally provided with toothings in actual application. Thus, the driving gear 12 can drive the rotating ring layer 14 to rotate. The rotating ring layer 14 can drive the electromagnetic column 7 to rotate. A scanner body 8 is arranged between the sliding plate 6 and the bottom of the gimbal placing frame 1. The scanner body 8 is suspended. Flaps 16 are arranged on the front face and the back face of the placing box 13. A handle 18 is connected to the top of the placing box 13. Support columns 20 are arranged on the bottom of the placing box 13 and the flaps 16. A rotating head 17 is movably connected to the middle of the top end of the placing box 13. A clamping head 19 is arranged on the top of the rotating head 17. The top of the rotating head 17 is clamped to the bottom of the gimbal placing frame 1.

[0026] The L-shaped design of the gimbal placing frame 1 is ergonomically optimized, which facilitates the operator to conveniently install and adjust the equipment in different scenes. The placing box 13 is made of light engineering plastic. The inside of the box wall is provided with a buffer layer, which can effectively reduce the influence of vibration on the equipment placed therein.

[0027] The permanent magnet 9 is made of neodymium-iron-boron strong magnetic material. The strong magnetic force of the permanent magnet 9 can generate sufficient repulsive force to suspend the scanner body 8. The bottom of the scanner body 8 is inlaid with magnetic material repelling the magnetic pole of the permanent magnet 9. Through accurate magnetic force calculation and adjustment, stable suspension is realized. The suspension design reduces the direct friction between the scanner body 8 and the gimbal placing frame 1, reduces mechanical wear and tear, prolongs the service life, and also provides smoother conditions for flexible rotation.

[0028] The limiting blocks 4 are made of rubber material, which is soft and elastic. On the one hand, it can limit the sliding range of the sliding plate 6 in the horizontal sliding groove 3 direction, prevent the sliding plate 6 from excessive displacement due to the failure of the driving motor set 2 or program out of control, and avoid damage to the equipment.

[0029] The driving motor set 2 is composed of high-precision stepping motors, which can accurately control the rotation angle and speed of the driving shaft 5. In close cooperation with the threads in the sliding plate 6, smooth and accurate linear transmission is achieved. When the driving motor set 2 receives a control signal to rotate, the driving shaft 5 drives the sliding plate 6 to slide in the transverse sliding groove 3 according to the set direction and speed, thereby adjusting the transverse position of the scanner body 8.

[0030] The electromagnetic column 7 generates a magnetic field when energized, which interacts with the rotating ring layer 14 to achieve a special rotation control function. The rotating ring layer 14 is made of a metal material with good magnetic conductivity, and the surface teeth are treated with special hardening to improve wear resistance. The bearing ring 15 is selected from high-precision ball bearings to ensure the stability of the electromagnetic column 7 during rotation and reduce radial and axial shaking. When the rotating motor 10 drives the driving gear 12 to rotate, it drives the rotating ring layer 14 to rotate, and the electromagnetic column 7 rotates synchronously under the action of the magnetic field, thereby accurately adjusting the angle of the scanner body 8 to meet different scanning needs.

[0031] The flip cover 16 is connected to the placement box 13 through a damping hinge, so that the flip cover 16 can move slowly and smoothly during opening and closing, avoiding internal equipment collision caused by rapid opening and closing. The bottom of the support column 20 is provided with a rubber non-slip pad to increase the friction with the placement plane and prevent the placement box 13 from sliding accidentally during use. The handle 18 is designed with ergonomics, and the surface is wrapped with soft rubber material, which is convenient for users to carry and reduces hand pressure. The swivel head 17 is internally provided with a universal joint structure, which can realize flexible rotation of the gimbal placement rack 1 relative to the placement box 13 at multiple angles, meeting the needs of rapid adjustment of the scanner angle in different terrains and use scenarios. The chuck 19 ensures the stability of the connection between the gimbal placement rack 1 and the swivel head 17, preventing loosening and falling off. Specific embodiment two:

[0033] Reference Figures 1-5 The permanent magnet 9 made of neodymium iron boron strong magnetic material at the bottom end of the gimbal placement rack 1 continuously releases strong magnetic force. The corresponding embedded magnetic pole repulsion magnetic material at the bottom of the scanner body 8 interacts with it. Based on the same repulsion characteristics, an upward repulsive force is generated to accurately offset the gravity of the scanner body 8, so that it is stably suspended above the bottom of the gimbal placement rack 1. This suspended state isolates direct contact between the two, eliminating the friction brought by traditional contact support, not only making the scanner body 8 rotate more flexible and free of any lag and obstruction, but also greatly reducing the wear of mechanical parts and prolonging the overall durability of the equipment, laying a solid foundation for subsequent accurate scanning operations.

[0034] When the device starts the scanning task, the control system sends an electrical signal to the drive motor group 2 according to the preset program or the real-time instruction of the operator. After receiving the signal, the high-precision stepper motor in the drive motor group 2 accurately drives the drive shaft 5 to rotate in a specific direction and at an accurate speed. The drive shaft 5 is made of high-strength alloy steel and finely ground threads, which are tightly engaged with the threads in the sliding plate 6, converting the rotational motion of the drive shaft 5 into the linear translation of the sliding plate 6. The sliding plate 6 slides along the transverse sliding groove 3. During this process, due to the flexible constraint of the limiting block 4 made of rubber material, it not only ensures that the sliding plate 6 will not deviate from the established track due to abnormal conditions, but also buffers possible collision impact, finally driving the suspended scanner body 8 above to realize accurate horizontal position adjustment and quickly locate the target scanning area.

[0035] When it is necessary to adjust the scanning angle of the scanner body 8, the rotating motor 10 receives the control instruction to start, drives the motor shaft 11 to rotate, and then drives the driving gear 12 connected thereto to rotate at high speed. The driving gear 12 is tightly engaged with the rotating ring layer 14 made of magnetically conductive metal and surface hardened tooth pattern, relying on the strong engagement force between the tooth patterns to force the rotating ring layer 14 to rotate synchronously. At this time, the electromagnetic column 7 is energized to excite a magnetic field, which interacts with the magnetic field of the rotating ring layer 14, and by means of electromagnetic induction principle, makes the electromagnetic column 7 closely follow the rotating ring layer 14 to rotate. As a key connecting component, the electromagnetic column 7 directly drives the scanner body 8 to change the angle smoothly, and the bearing ring 15 of the high-precision ball bearing stably supports the electromagnetic column 7, ensuring that the rotating process is stable and does not shake in the radial and axial directions, and can meet the complex and diverse scanning angle requirements in multiple angles.

[0036] In summary:

[0038] The permanent magnet 9 is made of neodymium iron boron strong magnetic material, and its strong magnetic force can generate enough repulsive force to make the scanner body 8 suspended. The bottom of the scanner body 8 is inlaid with a magnetic material repelling the magnetic pole of the permanent magnet 9, and through accurate magnetic force calculation and debugging, stable suspension is realized. The suspension design reduces the direct friction between the scanner body 8 and the gimbal holder 1, reduces mechanical wear and tear, improves the service life, and also provides smoother conditions for flexible rotation.

[0039] 2、The electromagnetic column 7 generates a magnetic field when energized, and interacts with the rotating ring layer 14 to realize a special rotating control function.

The bearing ring 15 selects high-precision ball bearings to ensure the stability of the electromagnetic column 7 during rotation and reduce radial and axial shaking. When the rotating motor 10 drives the driving gear 12 to rotate, the rotating ring layer 14 is driven to rotate, and the electromagnetic column 7 rotates synchronously under the action of the magnetic field, thereby accurately adjusting the angle of the scanner body 8 to meet different scanning requirements.

[0040] The flip cover 16 is connected with the placement box 13 through a damping hinge, so that the flip cover 16 can slowly and stably move during opening and closing, avoiding internal equipment collision caused by rapid opening and closing. The support column 20 is provided with a rubber anti-skid pad at the bottom to increase the friction with the placement plane and prevent the placement box 13 from accidentally sliding during use. The handle 18 is designed according to human engineering, and the surface is wrapped with soft rubber material, which facilitates the user to carry it by hand and reduces the hand pressure. The rotating head 17 is internally provided with a universal joint structure, which can realize flexible rotation of the gimbal placement rack 1 relative to the placement box 13 at multiple angles, meeting the demand for rapid adjustment of the scanner angle in different terrains and use scenarios, and the chuck 19 ensures the stability of the connection between the gimbal placement rack 1 and the rotating head 17, preventing loosening and falling off.
