Description

Technical Field

[0001] This utility model relates to the field of mobile communication technology, and in particular to the antenna tower top mechanism of a communication vehicle. Background Technology

[0002] A communication vehicle is a vehicle specifically designed to provide mobile communication services. It is typically equipped with advanced communication equipment, antennas, and transmission systems. It can provide stable wireless communication support in disaster relief, major events, temporary network coverage, and areas far from conventional communication facilities. By equipping itself with satellite communication, mobile base stations, and other equipment, a communication vehicle can support various communication needs such as wireless telephone, internet access, and broadcast transmission. It is widely used in disaster relief, law enforcement, military exercises, news reporting, and other occasions.

[0003] Currently, there are various types of communication vehicles on the market, but the antenna towers of these vehicles are often too tall, causing their tops to be exposed outside the vehicle and unable to be fully retracted into the passenger compartment. This can easily damage the antenna towers, affect the stability and driving safety of the vehicle, increase safety hazards, and limit the vehicle's adaptability and operational flexibility. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a communication vehicle antenna tower top mechanism.

[0005] This utility model is achieved using the following technical solution: a communication vehicle antenna tower top mechanism, including a flipping mechanism, an adjustment mechanism, and a protective mechanism, wherein the flipping mechanism is located inside the protective mechanism, and the adjustment mechanism is located inside the flipping mechanism;

[0006] The flipping mechanism includes a storage frame, a drive motor fixedly connected to the inner wall of the storage frame, a drive gear fixedly connected to the output end of the drive motor, a synchronous toothed belt meshing with the surface of the drive gear, a driven gear driving through the inner wall of the synchronous toothed belt, a worm fixedly connected to one side of the drive gear and the driven gear, a worm wheel meshing with the surface of the worm, a limit block fixedly connected to the inner side of the worm wheel, a base rotatably connected to the surface of the limit block, a base plate fixedly connected to the upper end of the limit block, and a support plate rotatably connected to the inner wall of the storage frame.

[0007] Through the above technical solution, the rotation of the worm gear drives the worm wheel to rotate synchronously, which can provide a higher reduction ratio, thereby driving the rotation of the limit block, making the rotation angle more precise and the overall operation more stable.

[0008] As a further improvement to the above solution, the worm is located on the left side of the drive motor, and the worm wheel is located at the upper end of the worm.

[0009] As a further improvement to the above solution, the limiting block is located inside the base, and the base is fixedly connected to the inner wall of the storage frame.

[0010] As a further improvement to the above solution, the adjustment mechanism includes an electric lifting rod, the output end of which is fixedly connected to a connecting plate, the surface of which is fixedly connected to a cantilever bracket, the surface of which is fixedly connected to a pitch push rod, the output end of which is fixedly connected to a base station antenna, the upper end of which is fixedly connected to a gimbal, the top of which is fixedly connected to a warning light, a lightning rod rotatably connected to one side of the warning light, and a microwave antenna rotatably connected to the other side of the warning light.

[0011] Through the above technical solution, the electric lifting rod can drive the connecting plate to rise, thereby raising the base station antenna to an appropriate height. The pitch push rod can flexibly adjust the angle of the base station antenna to ensure that the signal is always in the best state and improve the communication quality.

[0012] As a further improvement to the above solution, the number of cantilever supports is set to three, and the three cantilever supports are equidistantly distributed around the connecting plate, with the pitch push rod located on the outside of the cantilever support.

[0013] As a further improvement to the above solution, the protective mechanism includes a carriage body, and a rectangular groove is formed on the upper surface of the carriage body.

[0014] Using the above technical solution, the electric lifting rod drives the base station antenna through the rectangular slot and rises to the outside of the carriage body.

[0015] As a further improvement to the above solution, the storage frame is fixedly connected to the inner wall of the carriage body, and the electric lifting rod is fixedly connected to the upper end of the floor plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features a flipping mechanism. The drive motor, powered by an external power source, rotates the drive gear. The drive gear meshes with a synchronous belt, causing the driven gear to rotate synchronously. This, in turn, rotates the worm gear, which in turn rotates the worm wheel, which in turn rotates the limiting block. The limiting block, through the rotation of the worm wheel, enters the storage frame. The support plate provides effective auxiliary support to the base plate, thus improving the overall stability of the device during operation and preventing the base station antenna from swaying or tilting. The entire process ensures that the base station antenna can be placed horizontally inside the storage frame after folding and retracting, reducing exposed parts and improving vehicle adaptability and operational flexibility.

[0018] This invention, by setting an adjustment mechanism and a pitch push rod, enables the base station antenna to be adjusted within a certain angle, ensuring the optimal working state of the base station antenna in different working scenarios, improving signal reception and transmission efficiency. At the same time, the pan-tilt unit allows the lightning rod and microwave antenna to be flexibly adjusted in different environments, avoiding interference from external factors, thereby further ensuring the stability of the signal when the device is running in different environments.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0027] Please combine Figure 1-5 The communication vehicle antenna tower top mechanism of this embodiment includes a flipping mechanism 1, an adjustment mechanism 2 and a protective mechanism 3. The flipping mechanism 1 is located inside the protective mechanism 3, and the adjustment mechanism 2 is located inside the flipping mechanism 1.

[0028] The flipping mechanism 1 includes a storage frame 11. A drive motor 12 is fixedly connected to the inner wall of the storage frame 11. A drive gear 13 is fixedly connected to the output end of the drive motor 12. A synchronous toothed belt 14 meshes with the surface of the drive gear 13. A driven gear 15 drives the inner wall of the synchronous toothed belt 14. A worm gear 16 is fixedly connected to one side of the drive gear 13 and the driven gear 15. A worm wheel 17 meshes with the surface of the worm gear 16. A limit block 18 is fixedly connected to the inner side of the worm wheel 17. A base 19 is rotatably connected to the surface of the limit block 18. A base plate 191 is fixedly connected to the upper end of the limit block 18. A support plate 192 is rotatably connected to the inner wall of the storage frame 11. The rotation of the worm gear 16 drives the worm wheel 17 to rotate synchronously, which can provide a higher reduction ratio, thereby driving the rotation of the limit block 18, making the rotation angle more precise and the overall operation more stable.

[0029] The worm 16 is located to the left of the drive motor 12, and the worm wheel 17 is located at the upper end of the worm 16.

[0030] The limiting block 18 is located inside the base 19, and the base 19 is fixedly connected to the inner wall of the storage frame 11.

[0031] The adjustment mechanism 2 includes an electric lifting rod 21. A connecting plate 22 is fixedly connected to the output end of the electric lifting rod 21. A cantilever bracket 23 is fixedly connected to the surface of the connecting plate 22. A pitch push rod 24 is fixedly connected to the surface of the cantilever bracket 23. A base station antenna 25 is fixedly connected to the output end of the pitch push rod 24. A pan-tilt unit 26 is fixedly connected to the upper end of the connecting plate 22. A warning light 27 is fixedly connected to the top of the pan-tilt unit 26. A lightning rod 28 is rotatably connected to one side of the warning light 27, and a microwave antenna 29 is rotatably connected to the other side of the warning light 27. The electric lifting rod 21 can drive the connecting plate 22 to rise, thereby raising the base station antenna 25 to an appropriate height. The pitch push rod 24 can flexibly adjust the angle of the base station antenna 25 to ensure that the signal is always in the best state and improve the communication quality.

[0032] The number of cantilever supports 23 is set to three, and the three cantilever supports 23 are equidistantly distributed around the connecting plate 22. The pitch push rod 24 is located on the outside of the cantilever support 23.

[0033] The protective mechanism 3 includes a carriage body 31. A rectangular groove 32 is provided on the upper surface of the carriage body 31. The electric lifting rod 21 drives the base station antenna 25 through the rectangular groove 32 and rises to the outside of the carriage body 31.

[0034] The storage frame 11 is fixedly connected to the inner wall of the carriage body 31, and the electric lifting rod 21 is fixedly connected to the upper end of the base plate 191.

[0035] The implementation principle of the communication vehicle antenna tower top mechanism in this embodiment is as follows: When the base station antenna 25 needs to be retrieved, the operator first lowers it into the vehicle body 31 using a remote-controlled electric lifting rod 21. Then, the operator connects an external power source to start the drive motor 12. The drive motor 12 drives the drive gear 13 to rotate. The rotating drive gear 13 then drives the driven gear 15 to rotate via a synchronous belt 14, thereby causing the two worm gears 16 to rotate synchronously. The synchronously rotating worm gears 16 drive the worm wheel 17 to rotate together, thereby causing the limiting block 18 inside the base 19 to rotate. After rotating 90° counterclockwise, the limiting block 18 will enter the storage frame 11, thus completing the folding and retrieval of the base station antenna 25, placing it horizontally inside the vehicle body 31, improving the vehicle's adaptability. For adaptability and operational flexibility, the support plate 192 is used to provide auxiliary support for the base plate 191. When the base station antenna 25 is in operation, the operator can manually rotate the support plate 192 to remove it from the inside of the storage frame 11 and place one end inside the base plate 191 to limit the position of the base plate 191, thereby further improving the overall stability of the device during operation. When using the device, the base station antenna 25 can be adjusted at a certain angle by means of the pitch push rod 24, and the lightning rod 28 and microwave antenna 29 can be effectively adjusted by means of the gimbal 26, thereby ensuring that the signal is always in the optimal state. The connecting plate 22 is raised and lowered by means of the electric lifting rod 21, thereby raising the base station antenna 25 to the appropriate position. The entire device can realize the folding and retraction of the base station antenna 25, and at the same time, it can further ensure the stability of the signal and the overall stability of the device when the vehicle is in operation.
