Description

Technical Field

[0001] This invention belongs to the technical field of vehicle-mounted mobile communication equipment, specifically relating to a vehicle-mounted multi-antenna flipping and lifting device. Background Technology

[0002] Vehicle-mounted communication systems are a means of achieving high levels of informatization and intelligence by applying advanced wireless communication technology to vehicles, based on the development of intelligent transportation systems and sensor network technology. Currently, the design and research of vehicle-mounted multi-antenna flip-lifting devices is an important trend in the research and development of vehicle-mounted communication systems at home and abroad in recent years, which can better meet the mobility and efficiency requirements of vehicle-mounted equipment.

[0003] Existing antenna lifting and lowering devices can be divided into manual and automatic types. Manual devices are mechanical, requiring manual cranking for deployment and retrieval. When purely manual, operation is slow and inefficient. Automatic devices are electromechanical, using electrical and software controls for deployment and retrieval, and can also be remotely controlled. While electric control meets efficiency requirements, most lifting devices can only support one antenna. Adding a lifting mast when lifting multiple antennas increases material costs. Furthermore, existing lifting masts have limited lifting height, resulting in short antenna transmission distances. Current antenna lifting devices are mounted on vehicles, with the antenna directly mounted on top of the lifting mast without a lowering mechanism. This can lead to insufficient vehicle clearance due to the antenna's excessive height. If the antenna lifting device is not mounted on the vehicle, it must be carried by the vehicle and then removed and deployed on the surrounding open ground upon arrival. This requires laying ropes to secure the lifting device, making manual operation cumbersome and inefficient. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a vehicle-mounted multi-antenna flipping and lifting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vehicle-mounted multi-antenna tilting and lifting device includes a tilting and tilting device, a lifting device, and a vehicle-mounted device.

[0007] The tilting and flipping device includes an antenna, an antenna servo platform, and a tilting and flipping mechanism. The antenna servo platform is composed of a servo control unit vertically mounted below one end of the servo platform plate. The tilting and flipping mechanism is mounted at the other end of the servo platform plate. The antenna is mounted directly above the tilting and flipping mechanism. A pitching mechanism is horizontally mounted to the right of the tilting and flipping mechanism.

[0008] The lifting device includes a spring cable, an electric lifting rod, a lightning arrester, and a geared motor. The spring cable wraps around the electric lifting rod, the lightning arrester is installed on the electric lifting rod and passes through the antenna servo platform at the highest point, and the geared motor is installed side by side with the electric lifting rod in the vehicle compartment.

[0009] The vehicle-mounted device includes a control box and a vehicle-mounted compartment.

[0010] The antenna is a multi-type antenna, and multiple antennas can be installed on the tilting and flipping mechanism.

[0011] The tilting and flipping mechanism includes a DC motor and a worm gear reducer. The DC motor drives the azimuth shaft connected to the end of the reducer to rotate, thereby rotating the antenna. The tilting and flipping adjustment range is 0° to 180°, and the adjustment speed is 6° / s. The automatic unfolding / folding time is 30s.

[0012] The worm gear reducer has a self-locking function, and the antenna can be locked at any stop position; the pitch mechanism is designed with a manual port, and the antenna movement angle can be adjusted by manually cranking the handle in the event of a power failure.

[0013] The electric lifting pole is assembled from multiple aluminum tubes of varying sizes, allowing for easy adjustment of the lifting height, with an effective lifting height of no less than 10 meters.

[0014] When the electric lifting rod is in the closed state, after power is applied, the reduction motor moves the lowest aluminum tube section, and then all aluminum tube sections unfold synchronously. When the electric lifting rod unfolds to the limit position, the limit mechanism takes effect, and the electric lifting rod stops working.

[0015] When the electric lifting boom is in the lifting state, the geared motor rotates in the reverse direction, causing each section of the aluminum tube to descend synchronously. When the electric lifting boom is closed to the limit position, the limit mechanism takes effect, and the lifting boom stops working.

[0016] The deployment and retraction times of the lifting device are both no more than 3 minutes.

[0017] The geared motor is equipped with a manual port, which allows the height of the electric lifting rod to be adjusted manually by cranking the handle in the event of a power outage.

[0018] The control box consists of a main control board and a portable handheld remote control, which includes a button OLED screen, a switch, indicator lights, and an emergency stop button.

[0019] The button enables one-click deployment, one-click retraction, antenna angle adjustment, and electric lifting rod height adjustment of the vehicle-mounted multi-antenna flip-lift device, and displays the status information on the OLED screen.

[0020] The vehicle-mounted multi-antenna flipping and lifting device can operate normally in winds of force 8 and will not be damaged in winds of force 12.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. The lifting device is installed at the rear of the vehicle body, and its integrated design with the vehicle body eliminates the need to lay ropes to secure the lifting device after each trip to the destination, as well as the need for disassembly after completion. This improves work efficiency and wind resistance.

[0023] 2. The lifting device is assembled from aluminum tubes and can be manually or electrically adjusted to raise the height. The effective height can reach 10 meters, which can meet the antenna's information transmission distance. At the same time, it can be retracted into the vehicle compartment to ensure the vehicle's maneuverability.

[0024] 3. The tilting and flipping device can install multiple antennas to meet different needs, reduce the need for additional lifting rods, and save material costs. At the same time, the tilting and flipping device can adjust the antennas to any angle, improving the efficiency of information reception. When the vehicle is in motion, it can tilt and lie inside the carriage to meet the vehicle's maneuverability requirements.

[0025] 4. The lifting and lowering devices can be controlled manually or electrically. The electromechanical control solves the problem of rapid deployment and retraction of the vehicle-mounted antenna during lifting and lowering, reducing manual intervention and improving work efficiency. It can also be operated manually in the event of a power outage. Attached Figure Description

When the electric lifting boom 5 is in the closed state, upon power-on, the reduction motor 7 moves the lowest aluminum tube section, and then all aluminum tube sections unfold synchronously. When the electric lifting boom 5 reaches its limit position, the limit mechanism activates, and the electric lifting boom 5 stops working. When the electric lifting boom 5 is in the lifting state, the reduction motor 7 rotates in the reverse direction, causing all aluminum tube sections to descend synchronously. When the electric lifting boom 5 closes to its limit position, the limit mechanism activates, and the lifting boom stops working. A manual port is designed below the reduction motor 7, allowing adjustment of the electric lifting boom 5's height via a manual crank in the event of a power outage. The lifting device's unfolding and retraction times both do not exceed 3 minutes, and the effective lifting height is not less than 10 meters.
