Description

[0002] GPS positioning has become an indispensable part of many reconnaissance equipment. Its main body is relatively small. In order to ensure smooth communication, it needs to be extended to a certain height when in use. Differential GPS also has certain requirements for the distance between the primary and secondary GPS ends. This requires it to be installed on an antenna bracket and sent to the designated location by unfolding the bracket.

[0003] The accuracy of differential GPS is closely related to the distance between the primary and secondary GPS. The higher the accuracy required for the indicator, the greater the distance between the two.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely explain the technical solutions in the embodiments of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0036] See also Figure 1-12 In this embodiment, an antenna bracket includes a vertical arm and a rotating arm. The vertical arm is the basic support part of the entire bracket, providing a stable foundation for the installation of the rotating arm and the antenna. The rotating arm is responsible for realizing the extension and posture adjustment functions of the antenna, so that it can meet different usage requirements.

[0037] The vertical arm includes a first support airbag 1, a first reversing valve 2 and a first curved pipe 3. The upper end of the first support airbag 1 is connected to the first reversing valve 2 through a pipeline, and the upper end of the first reversing valve 2 is connected to the first curved pipe 3. The first support airbag 1 is in a compressed state when not inflated. When the antenna bracket needs to be used, the gas is controlled to enter the first support airbag 1 through the first reversing valve 2 to inflate it, thereby providing an upward support force for the entire bracket. The rotating connection end of the first curved pipe 3 is connected to the rotating arm, and its internal cavity structure serves as a gas transmission channel, while providing a connection basis for the rotation of the rotating arm.

[0038] The rotating arm includes a first control airbag 4, a first rotating tube 6, a first slider 7, a second reversing valve 8, a second supporting airbag 9, a third reversing valve 10, a second bent tube 11, a second control airbag 12, a second slider 13, a second rotating tube 15, a fourth reversing valve 16 and a third supporting airbag 17. The extension and posture adjustment functions of the antenna bracket can be realized through the rotating arm.

[0039] The first curved tube 3, the first rotating shaft 5 and the first rotating tube 6 are all hollow structures. The first curved tube 3 is provided with a first axial hole 23 and a first air hole 24, the first air hole 24 is connected to the inner cavity of the first curved tube 3, the first rotating shaft 5 is provided with a second air hole 26, the second air hole 26 is connected to the inner cavity of the first rotating shaft 5, the first rotating tube 6 is provided with a second axial hole 27 and a third air hole 28, the third air hole 28 is connected to the inner cavity of the first rotating tube 6, and the first axial hole 23 and the second axial hole 27 are located in a corresponding position, the first rotating shaft 5 is inserted into the first axial hole 23 and the second axial hole 27, the first air hole 24, the second air hole 26 and the third air hole 28 are located in a corresponding position, and the gas circulation is ensured. Such a structural design enables the gas to be smoothly transmitted from the vertical arm to each part of the rotating arm, providing a power source for the movement of the rotating arm.

[0040] The side of the first curved tube 3 is connected to the first control airbag 4, the first control airbag 4 is connected to the first slider 7, and the first slider 7 is slidably connected to the first rotating tube 6. The first rotating tube 6 is provided with a first slide groove 29, the first slider 7 is provided with a first pin 18, the first pin 18 is provided with a first sleeve 19, and the first sleeve 19 is slidably connected in the first slide groove 29. When the first control airbag 4 is inflated, it stretches and drives the first slider 7 to slide in the first slide groove 29. Since the first slider 7 is connected to the side of the first curved tube 3, and the first curved tube 3 is rotatably connected to the first rotating tube 6 through the first rotating shaft 5, the sliding of the first slider 7 will be converted into the rotation of the first rotating tube 6 around the first rotating shaft 5, so as to realize the extension action of the rotating arm.

[0041] The lower end of the first rotating tube 6 is connected to the second reversing valve 8, the second reversing valve 8 is connected to the second supporting airbag 9, the second supporting airbag 9 is connected to the third reversing valve 10, and the third reversing valve 10 is connected to the second curved tube 11. The structure of the second curved tube 11 is similar to that of the first curved tube 3, and the connection method between the second curved tube 11 and the second rotating tube 15 is also similar to the connection method between the first curved tube 3 and the first rotating tube 6. The second curved tube 11, the second rotating shaft 14 and the second rotating tube 15 are all hollow structures. The second curved tube 11 is provided with a third axial hole 30 and a fourth air hole 31. The fourth air hole 31 is connected to the inner cavity of the second curved tube 11. The second rotating shaft 14 is provided with a fifth air hole. The second rotating tube 15 is provided with a fourth axial hole 32 and a sixth air hole 33. The fifth air hole is connected to the inner cavity of the second rotating tube 15. The third axial hole 30 corresponds to the fourth axial hole 32. The second rotating shaft 14 is inserted into the third axial hole 30 and the fourth axial hole 32. The fourth air hole 31, the fifth air hole and the sixth air hole 33 correspond to each other to ensure gas circulation. The side of the second curved tube 11 is connected to the second control airbag 12. The second control airbag 12 is connected to the second slider 13. The second slider 13 is slidably connected to the second rotating tube 15. The second rotating tube 15 is provided with a second slide groove 34, the second slider 13 is provided with a second pin shaft 20, the second pin shaft 20 is provided with a second sleeve 21, and the second sleeve 21 is slidably connected in the second slide groove 34. The working principle of the second control airbag 12 is the same as that of the first control airbag 4. When inflated, it drives the second slider 13 to move, thereby causing the second rotating tube 15 to rotate around the second rotating shaft 14, further expanding the extension range of the rotating arm.

[0042] The second rotating tube 15 is connected to the fourth reversing valve 16, and the fourth reversing valve 16 is connected to the third supporting airbag 17. The third supporting airbag 17 is inflated in the working state to provide support for the end of the antenna bracket to ensure that the antenna can be stably located at a specified position.

[0043] The first rotating shaft 5 and the second rotating shaft 14 are both provided with sealing grooves 25, and sealing strips 22 are installed on the sealing grooves 25. These sealing strips 22 can effectively prevent gas from leaking from the shaft hole and the air hole during rotation, ensure the sealing of the entire pneumatic system, and ensure the normal operation of the antenna bracket.

[0044] The antenna brackets described in this embodiment can be used in pairs, and the primary GPS and the secondary GPS are respectively set on the third support airbags 17 of the two antenna brackets to ensure the accuracy of the differential GPS. Fig.13 As shown, the first curved pipe 3 is provided with two rotating connection ends, and the two rotating connection ends are respectively connected with rotating arms. The third supporting airbags 17 of the two rotating arms are respectively provided with the main GPS and the secondary GPS to ensure the accuracy of the differential GPS.

[0045] The antenna bracket of this embodiment includes a storage state and a working state when in use, which are as follows:

[0046] In the storage state, the first support airbag 1, the first control airbag 4, the second support airbag 9, the second control airbag 12 and the third support airbag 17 are all deflated and compressed to the smallest state. At this time, each airbag of the antenna bracket is in a contracted state, and the entire bracket can be folded up, occupying the smallest space, which is convenient for storage and carrying. For example, when the antenna bracket is not in use in the reconnaissance equipment, it can be stored in the specific storage space of the equipment without affecting other functions and overall layout of the equipment.

[0047] When the antenna bracket needs to be used to place the antenna at the specified position, it enters the working state. In the working state, the first reversing valve 2 controls the inflation of the first support airbag 1 and / or the first control airbag 4. If the antenna bracket only needs to be initially raised, only the first support airbag 1 can be inflated to gradually extend and provide an upward support force so that the antenna bracket begins to rise. If a part of the rotating arm needs to be unfolded at the same time, the first control airbag 4 can be controlled to inflate. The extension of the first control airbag 4 drives the movement of the first slider 7. The first slider 7 slides along the first slide groove 29 of the first rotating tube 6. Due to the above-mentioned connection relationship, the sliding of the first slider 7 will drive the first rotating tube 6 to rotate along the first rotating shaft 5, thereby realizing the initial extension of the rotating arm. The second reversing valve 8 controls the second support airbag 9 to inflate and extend, further increasing the length of the rotating arm so that the antenna can reach the corresponding position. The third reversing valve 10 controls the inflation of the second control airbag 12, and the extension of the second control airbag 12 drives the second slider 13 to move, and the second slider 13 slides along the second slide groove 34 of the second rotating tube 15, driving the second rotating tube 15 to rotate along the second rotating shaft 14, further extending the extension range of the rotating arm, so that the antenna can reach a farther position or be adjusted to a suitable angle. The fourth reversing valve 16 controls the inflation and extension of the third support airbag 17 to provide stable support for the end of the antenna bracket, ensuring that the antenna can be stably maintained at the specified position during operation, ensuring smooth communication.

[0048] During the entire working process, the posture of the antenna bracket can be changed by accurately controlling the inflation sequence and inflation pressure of the first support airbag 1, the first control airbag 4, the second support airbag 9, the second control airbag 12 and the third support airbag 17. For example, if the antenna bracket needs to be tilted to one side at a certain angle to avoid obstacles, the control airbag on one side can be inflated first to make it rotate accordingly, and then the inflation amount of other airbags can be adjusted to stabilize the posture of the bracket. Or if the antenna needs to be sent to a higher or farther position, the inflation pressure of the first support airbag 1 and the second support airbag 9 can be appropriately increased, and the extension angle of the rotating arm can be reasonably controlled to achieve the best antenna height and signal reception effect.

[0049] In this embodiment, each reversing valve can control each airbag individually. At the same time, since the first curved pipe 3, the first rotating shaft 5, the first rotating pipe 6, the second curved pipe 11, the second rotating shaft 14 and the second rotating pipe 15 are all connected cavity structures, each reversing valve can also synchronously control the airbags. At this time, the gas enters from the first supporting airbag 1, and then flows through the entire bracket through the cavity structure to realize the integrated deployment of the antenna bracket.

[0050] The present embodiment will be described below in combination with actual application scenarios:

[0051] 1. Mobile reconnaissance equipment scenario. In field mobile reconnaissance missions, the reconnaissance equipment needs to be quickly deployed at different locations and perform communication and positioning work. The antenna bracket of the present invention can be conveniently stored in the outer shell of the reconnaissance equipment or a special storage box when in storage, without taking up too much space. When arriving at the designated location, the operator can quickly take out the antenna bracket, and inflate the airbag by controlling each reversing valve according to the operating method of the working state, so that the antenna bracket can be quickly deployed and the antenna can be lifted to a suitable height and angle. For example, in a mountainous environment, there may be obstacles such as trees and rocks. The operator can flexibly adjust the posture of the antenna bracket according to the actual situation, and by changing the inflation order and air pressure, the antenna can avoid obstacles to ensure the accuracy and stability of GPS positioning and communication.

[0052] 2. Vehicle-mounted reconnaissance equipment scenario. For vehicle-mounted reconnaissance equipment, the vehicle may encounter different terrains and environments during driving. When the antenna bracket is installed on the vehicle, it can be kept in storage while the vehicle is driving to reduce wind resistance and occupy space. When the vehicle arrives at the location where reconnaissance work is required and stops, the antenna bracket can be quickly started in working state. For example, in an urban environment, high-rise buildings may block the signal. At this time, the controllability of the antenna bracket can be used to adjust the height and angle of the antenna so that the differential GPS can obtain a better signal, improve positioning accuracy, and meet the requirements of the reconnaissance mission for the accuracy of location information.

[0053] The present invention adopts an airbag as the main structure. Compared with the traditional antenna bracket made of hard materials, the airbag is extremely light when not inflated, which greatly reduces the weight of the entire antenna bracket. This is very important for reconnaissance equipment that has strict requirements on the weight of each device in modern diversified equipment. It will not occupy too much weight resources and is convenient for the overall layout and carrying of the equipment. Since the airbag can be deflated and compressed to the minimum state in the storage state, the storage volume of the antenna bracket is greatly reduced. Even if a folding or telescopic mechanism is adopted, the storage volume of the traditional antenna bracket can only be reduced to a certain extent, while the antenna bracket of the present invention can be more compact when stored, which is convenient for storage in a limited space, thereby improving the portability and storage efficiency of the equipment. The airbag is adopted as the control structure, and the airbag is arranged in each part that needs to move. By controlling the inflation sequence and pressure of different airbags, the predetermined movement can be achieved, and the movement stroke can be accurately changed. This motion controllability makes the antenna bracket more flexible, and the posture can be adjusted according to the actual situation, which is convenient for crossing some obstacles, and improves the adaptability and practicality of the antenna bracket in complex environments.

[0054] In summary, the antenna bracket and the use method thereof of the present invention effectively solve the problems of heavy weight, large storage volume and lack of controllability of traditional antenna brackets, and have important practical application value.

[0055] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. According to the content of this specification, many modifications and changes can be made. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
