Servo-stabilized platform

Abstract

This utility model relates to the field of stabilization platform technology, specifically a servo stabilization platform, including a base frame, a horizontal angle adjustment section, a pitch angle adjustment section, and limiting sections. The horizontal angle adjustment section is located above the base frame and is used to adjust the horizontal rotation angle of the servo stabilization platform. The pitch angle adjustment section is located on the horizontal angle adjustment section and is used to mount equipment and adjust the pitch angle of the equipment. Several limiting sections are located on the horizontal angle adjustment section and are used to limit the maximum pitch angle of the pitch angle adjustment section. This utility model adjusts the horizontal rotation angle of the equipment by setting a yaw axis and adjusts the pitch angle of the equipment by setting pitch blocks. Buffer columns that increase in size from top to bottom sequentially contact the rotating equipment mounting frame, causing it to experience increasing resistance until it stops rotating. The resistance on the equipment mounting frame increases slowly, causing it to stop slowly and avoiding equipment vibration due to rigid contact. The blocking blocks can be quickly replaced by turning a threaded rod.

Description

Technical Field

[0001] This utility model relates to the field of stabilization platform technology, and in particular to a servo stabilization platform. Background Technology

[0002] With the rapid development of autonomous driving and remote control technologies, unmanned ground vehicles (UGVs) are increasingly widely used in fields such as military reconnaissance, fire rescue, material transportation, high-altitude operations, and environmental monitoring. However, when UGVs travel in the wild or on unstructured road environments, they inevitably encounter complex conditions such as uneven road surfaces, emergency steering, and acceleration and braking, resulting in continuous multi-axial angular motions and linear vibrations, including pitch, roll, and yaw. This bumping and shaking transmitted from the vehicle can severely and adversely affect the normal operation of onboard mission equipment.

[0003] For many sophisticated vehicle-mounted devices, such as electro-optical reconnaissance cameras, LiDAR, communication antennas, monitoring sensors, or robotic arms, their performance is highly dependent on stable and precise spatial pointing. For example, in the case of an electro-optical pod, severe vehicle shaking can cause blurred or jittery images, or even cause targets to move out of the field of view, significantly reducing reconnaissance efficiency and image intelligence quality. For LiDAR, a stable platform is fundamental to ensuring accurate point cloud data and avoiding registration errors. And for communication antennas, stable pointing is the lifeline for maintaining an uninterrupted, high-quality data link.

[0004] To address these issues, the key lies in isolating the motion transmission between the vehicle body and the mission equipment. Traditional rigid mounting methods clearly cannot overcome this challenge. Therefore, employing a servo-stabilized platform has become a crucial technology for improving the operational efficiency of onboard equipment in unmanned vehicles. Utility Model Content

[0005] The main objective of this invention is to provide a servo stabilization platform to solve the problems raised in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a servo stabilization platform is provided, including a base frame and further comprising:

[0007] A horizontal angle adjustment section, located above the base frame, is used to adjust the horizontal rotation angle of the servo stabilization platform;

[0008] A pitch adjustment section is provided on the horizontal adjustment section, used to install equipment, and can adjust the pitch angle of the equipment;

[0009] The limiting part, which consists of several parts, is provided on the horizontal angle adjustment part and is used to limit the maximum pitch angle of the pitch adjustment part.

[0010] Furthermore, the horizontal angle adjustment part includes a heading axis and a base block. The bottom end of the heading axis is rotatably connected to the base frame, and the top end is rotatably connected to the base block. Supports are fixedly provided on both sides of the base block.

[0011] Furthermore, the bracket has several grooves on its inner side and several holes on the side adjacent to the inner side, the grooves and holes being used to install the limiting part.

[0012] Furthermore, the pitch adjustment unit includes a device mounting frame and a pitch block. The device mounting frame is rotatably disposed between two supports, and the pitch block is fixedly disposed on the top outer side of one of the supports.

[0013] Furthermore, a functional module is fixedly provided on the outer side of the pitch block.

[0014] Furthermore, the limiting part includes a blocking block and a limiting block fixed inside the blocking block. The limiting block has a receiving hole, and the outer contour dimension of the limiting block is smaller than the outer contour dimension of the blocking block.

[0015] Furthermore, the blocking block is fan-shaped, and a number of buffer pillars are fixedly provided on the lower side of the fan-shaped limiting block, with the length of the buffer pillars increasing sequentially from top to bottom.

[0016] Furthermore, the limiting part also includes a threaded rod and a nut. A stop is fixedly provided at the top of the threaded rod, and the outer ring of the threaded rod is provided with two threads with different pitches. The nut is only adapted to the thread at the end closest to the stop.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention allows for adjustment of the horizontal rotation angle of the equipment by setting a yaw axis, and for adjustment of the pitch angle by setting a pitch block. The buffer columns, increasing in size from top to bottom, sequentially contact the rotating equipment mounting frame, increasing the resistance until it stops rotating. The resistance on the equipment mounting frame increases slowly, causing it to stop gradually, avoiding equipment vibration caused by rigid contact. The blocking blocks can be quickly replaced by turning a threaded rod. Attached Figure Description

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] This embodiment provides a servo stabilization platform, such as Figure 1 As shown, it includes a chassis 1, which is mounted on the unmanned vehicle, and also includes:

[0026] The horizontal angle adjustment section is located above the base frame 1 and is used to adjust the horizontal rotation angle of the servo stabilization platform.

[0027] The pitch adjustment section is located on the horizontal adjustment section and is used to install equipment and adjust the pitch angle of the equipment.

[0028] Limiting part 6, there are several limiting parts 6, all of which are provided on the horizontal angle adjustment part, and are used to limit the maximum pitch angle of the pitch adjustment part.

[0029] The horizontal adjustment section includes a yaw axis 2 and a base block 3. The bottom end of the yaw axis 2 is rotatably connected to the base frame 1, and the top end is rotatably connected to the base block 3. Supports 4 are fixedly installed on both sides of the base block 3. A second servo motor is installed inside the yaw axis 2 to drive the base block 3 to rotate. When the base block 3 rotates, the horizontal rotation angle of the equipment mounting bracket 5 on the support 4 can be adjusted.

[0030] like Figure 2 As shown, the inner side of the bracket 4 is provided with several grooves 41, and the adjacent side of the inner side is provided with several holes 42. The grooves 41 and the holes 42 are used to install the limiting part 6.

[0031] The pitch adjustment unit includes a mounting bracket 5 and a pitch block 8. The mounting bracket 5 is rotatably mounted between two supports 4, and the pitch block 8 is fixedly mounted on the top outer side of one of the supports 4. The mounting bracket 5 is used to mount the equipment, and the pitch block 8 houses a first servo motor that drives the mounting bracket 5 to pitch. The mounting bracket 5 and the supports 4 are connected by a crossed roller bearing, which ensures smooth rotation and reduces friction.

[0032] A functional module 7 is fixedly mounted on the outer side of the pitch block 8. Functional module 7 integrates a laser rangefinder, a low-light night vision device, an infrared thermal imager, and an infrared laser illuminator. The laser rangefinder accurately measures the target distance by emitting an invisible laser pulse towards the target, calculating the round-trip time of the laser, and determining the precise distance based on the speed of light. The low-light night vision device images under extremely low ambient light conditions such as starlight and moonlight, amplifying the weak visible and near-infrared ambient light through an image intensifier and converting it into a visible image. The infrared thermal imager detects and images the thermal radiation of objects, capturing the mid- and far-infrared radiation emitted by objects using an infrared detector, displaying different colors for different temperatures, such as white-hot and black-hot modes, enabling operation even in truly "completely dark" environments. The infrared laser illuminator provides active illumination for the low-light camera, emitting near-infrared laser light invisible to the human eye to illuminate the target. The low-light camera can receive this light and form a clear image without the target noticing.

[0033] Functional module 7 also integrates actuators, controllers, receivers, etc. The controller collects the tilt angle signal of the equipment and sends the signal to the receiver. After receiving the signal, the receiver sends a command to the actuator. After receiving the command, the actuator controls the first servo motor and the second servo motor to work and adjust the rotation state of the equipment.

[0034] like Figure 3 As shown, the limiting part 6 includes a blocking block 61 and a limiting block 62 fixedly disposed inside the blocking block 61. The limiting block 62 is provided with a receiving hole 64, and the outer contour dimension of the limiting block 62 is smaller than the outer contour dimension of the blocking block 61.

[0035] The blocking block 61 is fan-shaped, and several buffer pillars 63 are fixedly provided on the lower side of the fan-shaped limiting block 62. The length of the buffer pillars 63 increases from top to bottom. The buffer pillars 63 are made of elastic material, which deforms under pressure to absorb energy and can return to their original shape after the pressure is released. When the equipment mounting frame 5 rotates, it first contacts the longer lower buffer pillars 63 and is blocked by them, slowing down the rotation speed. As the rotation continues, more and more buffer pillars 63 come into contact, and the resistance it experiences increases until it stops rotating. The resistance experienced by the equipment mounting frame 5 increases slowly, causing it to stop slowly and avoiding equipment vibration caused by rigid contact.

[0036] The limiting part 6 also includes a threaded rod 65 and a nut 67. A stop 66 is fixedly provided at the top of the threaded rod 65. The outer ring of the threaded rod 65 has two sections of threads with different pitches. The nut 67 only fits the thread at the end closest to the stop 66. The outer diameter of the stop 66 is larger than the inner diameter of the nut 67 to prevent the stop 66 from being screwed into the nut 67, which would prevent the threaded rod 65 from being screwed out. The nut 67 is rotatably connected to the bracket 4. The receiving hole 64 has a thread that only fits the end furthest from the stop 66. This section of the threaded rod 65 can be screwed into the receiving hole 64. The blocking block 61 is fixed to the inside of the bracket 4 by the limiting block 62. When the equipment mounting frame 5 rotates vertically and abuts against the blocking block 61, the equipment mounting frame 5 cannot continue to rotate, thereby limiting the maximum pitch angle of the equipment. The threaded rod 65 with two sections of threads with different pitches can be driven in and out of the receiving hole 64 by the nut 67, and can also prevent the threaded rod 65 from falling out of the nut 67. When the bottom end of the threaded rod 65 is screwed out of the receiving hole 64, its lower thread just contacts the nut 67, and the threaded rod 65 can no longer rotate. At this time, the blocking block 61 and the limiting block 62 can be removed for easy replacement.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
