Description
Technical Field
[0001] This utility model relates to the field of laser transmitter technology, specifically to a gimbal structure for an anti-vibration laser transmitter. Background Technology
[0002] In fields such as industrial measurement, laser communication, and precision machining, the stable operation of laser emitters is crucial. The stability of laser emission directly affects measurement accuracy, communication quality, and processing results. Currently, laser emitters are usually mounted on gimbals to enable multi-directional angle adjustment. When in use, the omnidirectional gimbal relies on a dual-axis rotation mechanism consisting of a first and a second mutually perpendicular rotation axis to drive the laser emitter head to achieve 360° angle adjustment without dead angles. This meets the flexible adjustment needs of the laser emission direction in different scenarios, ensuring that the laser can be accurately aimed at the target position. At the same time, it can transmit signals to the controller, which drives a micro drive motor to fine-tune the angle of the dual rotation axis, actively counteracting the angle deviation caused by vibration, further ensuring the stability and accuracy of laser emission, so that the laser can still maintain a precise emission state even in a vibration environment. Traditional laser emitter mounting structures often employ rigid connections or single-spring damping designs, which are ill-suited to handling multi-directional, high-frequency composite vibrations. While rigid connections ensure structural stability, their vibration transmission efficiency is extremely high, making them almost incapable of buffering external impacts. In contrast, while single-spring damping can absorb some low-frequency vibrations, it is prone to resonance under high-frequency vibrations and lacks effective constraints on lateral and tilting vibrations, resulting in significant attitude deviations in the laser emitter.
[0003] Therefore, a gimbal structure for a vibration-resistant laser transmitter is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a universal gimbal structure for a vibration-resistant laser transmitter to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A gimbal structure for a vibration-resistant laser emitter includes a mounting base, a chassis on top of the mounting base, a laser emitter body mounted on top of the chassis, and a vibration-resistant mechanism between the mounting base and the chassis. The vibration-damping mechanism includes a rotating box, inside which a nylon rod is movably engaged. A shock-absorbing spring is fitted onto the nylon rod. A sliding rod is fixedly connected to the outer bottom of the nylon rod. A sliding groove is formed in the side wall of the rotating box. A moving block is fixedly connected to the end of the sliding rod away from the nylon rod. A connecting rod is fixedly connected to the outer side of the moving block. A pressing rod is fixedly connected to the outer side of the connecting rod. A storage compartment is provided on the top of the chassis, and an elastic airbag is installed inside the storage compartment.
[0006] As a further optimization of this utility model, the mounting base and the outer side of the chassis are provided with a stabilizing mechanism. The stabilizing mechanism includes an L-shaped plate, and the inner side of the L-shaped plate is provided with a moving groove. A connecting rod is slidably connected inside the moving groove.
[0007] As a further optimization of this utility model, the chassis is located directly above the mounting base, the operating box is fixedly connected to the directly above the mounting base, and the bottom of the nylon rod is movably connected to the inside of the operating box.
[0008] As a further optimization of this utility model, the top of the nylon rod is fixed and symmetrically distributed at the bottom of the chassis, the slide rod is slidably connected inside the slide groove, and the moving block is slidably connected to the outside of the operating box.
[0009] As a further optimization of this utility model, the connecting rod and the compression rod are movably connected above the mounting base, and the compression rod is located directly above the elastic airbag.
[0010] As a further optimization of this utility model, the L-shaped plates are fixed and symmetrically distributed on the outside of the mounting base, and the top of the L-shaped plates is located on the outside of the chassis.
[0011] As a further optimization of this utility model, the end of the connecting rod away from the moving groove is fixedly connected to the outside of the chassis, and the connecting rods are symmetrically distributed on the outside of the chassis.
[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a chassis drives a nylon rod to move within a rotating box. The shock-absorbing spring on the nylon rod undergoes elastic deformation, initially buffering vibration energy. Simultaneously, the nylon rod drives a sliding rod to slide within a groove, causing the moving block, connecting rod, and pressing rod to move in tandem. The pressing rod compresses the elastic airbag within the storage compartment, and the elastic airbag further absorbs vibration energy using its own elasticity. Through the synergistic effect of the mechanical structure and elastic elements, the impact of vibration on the laser emitter head is significantly reduced, ensuring the stability and accuracy of laser emission.

Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0017] Please see Figures 1-6 This utility model provides a technical solution: A gimbal structure for a vibration-resistant laser emitter includes a mounting base 1, a chassis 2 on the top of the mounting base 1, a laser emitter body 3 mounted on the top of the chassis 2, and a vibration-resistant mechanism 4 between the mounting base 1 and the chassis 2. The vibration-damping mechanism 4 includes a rotating box 41, inside which a nylon rod 42 is movably engaged. A shock-absorbing spring 43 is fitted on the nylon rod 42. A slide rod 44 is fixedly connected to the bottom outer side of the nylon rod 42. A slide groove 45 is opened in the side wall of the rotating box 41. A moving block 46 is fixedly connected to the end of the slide rod 44 away from the nylon rod 42. A connecting rod 47 is fixedly connected to the outer side of the moving block 46. A compression rod 48 is fixedly connected to the outer side of the connecting rod 47. A storage compartment 49 is provided on the top of the chassis 2. An elastic airbag 410 is installed inside the storage compartment 49.
[0018] It should be noted that: the chassis 2 is located directly above the mounting base 1, the operating box 41 is fixedly connected to the top of the mounting base 1, the bottom of the nylon rod 42 is movably connected to the inside of the operating box 41, the top of the nylon rod 42 is fixed and symmetrically distributed at the bottom of the chassis 2, the slide rod 44 is slidably connected to the inside of the slide groove 45, the moving block 46 is slidably connected to the outside of the operating box 41, the connecting rod 47 and the squeezing rod 48 are movably connected above the mounting base 1, and the squeezing rod 48 is located directly above the elastic airbag 410.
[0019] Furthermore, the nylon rod 42 is made of nylon material, which utilizes its own toughness and wear resistance to reduce mechanical wear during repeated movements. At the same time, it helps to absorb high-frequency vibrations. When the elastic airbag 410 is squeezed, the internal gas will generate a reverse thrust, forming a flexible buffer to further absorb the remaining vibration energy. Meanwhile, the symmetrically distributed nylon rod 42 and the compression rod 48 ensure that the vibration energy is dispersed in all directions, avoiding the laser emitter head from deflection caused by excessive local force.
[0020] Specifically: When external vibrations (such as equipment vibration or environmental turbulence) are transmitted to the mounting base (1), the chassis 2 will move up and down or tilt slightly with the vibration, causing the nylon rods 42 symmetrically distributed at the bottom to move in the operating box 41. At this time, the shock-absorbing springs 43 sleeved on the nylon rods 42 will deform (stretch or compress) due to the extension and contraction of the nylon rods 42, and absorb part of the vibration energy through the elastic potential energy of the spring to achieve initial buffering.
[0021] As a further implementation of this solution, a stabilizing mechanism 5 is provided on the outer side of the mounting base 1 and the chassis 2. The stabilizing mechanism 5 includes an L-shaped plate 51, and a moving groove 52 is provided on the inner side of the L-shaped plate 51. A connecting rod 53 is slidably connected inside the moving groove 52.
[0022] It should be noted that: the L-shaped plate 51 is fixed and symmetrically distributed on the outside of the mounting base 1, and the top of the L-shaped plate 51 is located on the outside of the chassis 2. The end of the connecting rod 53 away from the moving groove 52 is fixedly connected to the outside of the chassis 2, and the connecting rod 53 is symmetrically distributed on the outside of the chassis 2.
[0023] Furthermore, the connecting rod 53 on the outer side of the chassis 2 is embedded in the moving groove 52 on the inner side of the L-shaped plate 51. When the chassis 2 moves slightly due to vibration, the connecting rod 53 slides along the moving groove 52. Through the limiting effect of the moving groove 52, the shaking amplitude of the chassis 2 is constrained (such as preventing excessive tilting or displacement), ensuring that the buffering effect of the anti-vibration mechanism 4 is effectively utilized.
[0024] It should be noted that the device is based on the mounting base 1, and its top is connected to the chassis 2 through the anti-vibration mechanism 4. The laser emitter body 3 is installed on the chassis 2. At the same time, a stabilizing mechanism 5 is added to the outside of the mounting base 1 and the chassis 2 to form a three-layer stabilization system of "support-buffering-limiting" to reduce the interference of vibration on the laser emitter from the source.
[0025] Workflow: When the overall structure is subjected to external vibration, the chassis 2 on which the laser emitter body 3 is located will generate corresponding displacement. Since the top of the nylon rod 42 is fixed and symmetrically distributed at the bottom of the chassis 2, the displacement of the chassis 2 will drive the nylon rod 42 to move within the operating box 41. The operating box 41 is fixedly connected to the top of the mounting base 1, providing space for the nylon rod 42 to move. At this time, the shock-absorbing spring 43 sleeved on the nylon rod 42 will undergo elastic deformation due to the movement of the nylon rod 42, using the spring force to initially buffer and absorb the vibration energy, reducing the transmission of vibration to the chassis 2 and the laser emitter body 3. Meanwhile, a sliding rod 44 is fixedly connected to the bottom outer side of the nylon rod 42. During the movement of the nylon rod 42, the sliding rod 44 slides within the groove 45 opened on the side wall of the operating box 41 as the nylon rod 42 moves. The moving block 46, fixedly connected to the end of the sliding rod 44 away from the nylon rod 42, slides along the outer side of the operating box 41 under the drive of the sliding rod 44. The connecting rod 47 fixedly connected to the outer side of the moving block 46 and the pressing rod 48 fixedly connected to the outer side of the connecting rod 47 will also be linked. Since the pressing rod 48 is located directly above the elastic airbag 410 installed in the storage slot 49 at the top of the mounting base 1, the movement of the pressing rod 48 will compress the elastic airbag 410. The elastic airbag 410 uses its own elasticity to further absorb and consume the energy generated by vibration. Together with the shock-absorbing spring 43, it forms a double shock-absorbing effect, effectively reducing the impact of vibration on the laser emitter body 3 and ensuring the stability of its laser emission. In terms of stability, the stabilizing mechanism 5 plays a role in limiting excessive shaking of the chassis 2 and enhancing the overall structural stability. The L-shaped plate 51 is fixed and symmetrically distributed on the outside of the mounting base 1, with its top located on the outside of the chassis 2, providing a lateral support frame for the chassis 2. When the chassis 2 is displaced under vibration, the connecting rod 53 fixedly connected to its outside will slide in the moving groove 52 opened on the inside of the L-shaped plate 51. This sliding connection allows the chassis 2 to adapt to vibration within a certain range, ensuring that the anti-vibration mechanism 4 can function normally. At the same time, through the cooperation of the L-shaped plate 51 and the connecting rod 53, the shaking amplitude of the chassis 2 is limited, preventing the chassis 2 from becoming unbalanced due to excessive shaking, and further ensuring the working stability of the laser emitter body 3.
