Description

Technical Field

[0001] The utility model belongs to the technical field of data acquisition devices, and particularly relates to a low-latency flight control sensor data acquisition device. Background Art

[0002] Flight control sensor data acquisition devices play a crucial role in modern aerospace and unmanned aerial vehicle technologies. These devices are responsible for collecting and processing a large amount of data generated during the flight of the aircraft, including information such as attitude, speed, and acceleration. This data is vital for flight control, navigation, and safety management. Existing flight control sensor data acquisition devices are usually installed at various key positions of the aircraft, collect data in real time through sensors, and transmit it to the flight control computer for processing to ensure the stable and precise operation of the aircraft.

[0004] The above device adopts the technical means that each sensor individually occupies a data interface, a functional module is established for each sensor inside the programmable logic device, and the collected data is stored in the register corresponding to each data interface in parallel. Each sensor can collect data according to its own frequency according to the requirements of the flight control system, ensuring the time correlation between each sensor. However, when using the above device, there are still some deficiencies. First, since the aircraft will experience various vibrations and impacts during flight, this data acquisition device is prone to being interfered by these external factors, resulting in inaccurate and unstable collected data. Second, many existing devices lack effective fixing and buffering mechanisms, so that the data acquisition device body is prone to displacement or damage in a severe flight environment. In addition, the sizes and shapes of sensor data acquisition devices for different aircraft are different, and existing devices are difficult to adapt to these differences, lacking flexibility and versatility. Therefore, a new low-latency flight control sensor data acquisition device is needed, which can protect the data acquisition device in a vibration and impact environment, improve data accuracy and stability, and at the same time has strong adaptability and can adapt to data acquisition devices of different sizes and dimensions.

[0026] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a low-latency flight control sensor data acquisition device, including a data acquisition device body 1. The lower end of the data acquisition device body 1 is movably connected to a carrying and placing plate 2, and a buffer mechanism 10 is fixedly connected to the lower end of the carrying and placing plate 2;

[0028] The buffer mechanism 10 includes a connecting block 101 fixedly connected to the outer wall of the lower end of the carrying and placing plate 2. One side outer wall of the lower end of the connecting block 101 is fixedly connected to a fixing block 102. Two limiting rods 103 are slidably connected to the fixing block 102. The upper outer wall of the limiting rod 103 is movably connected to a first spring 104, and the lower outer wall of the limiting rod 103 is movably connected to a second spring 105. The first spring 104 connected to the upper outer wall of the limiting rod 103 is arranged above the fixing block 102, and the second spring 105 connected to the lower outer wall of the limiting rod 103 is arranged below the fixing block 102. The bottom end of the limiting rod 103 is fixedly connected to a base 106. Both sides of the upper outer wall of the base 106 are fixedly connected to second limiting blocks 107. A limiting groove 108 is opened on one side of the second limiting block 107. The limiting groove 108 opened on one side of the second limiting block 107 is slidably connected to the outer wall of one side of the connecting block 101. There are two second limiting blocks 107, and the bottom ends of both are fixedly connected to the upper outer wall of the base 106.

[0029] By providing a data acquisition device body 1, a carrying and placing plate 2 is movably connected to the bottom end of the data acquisition device body 1. Therefore, the data acquisition device body 1 can be placed on the carrying and placing plate 2 to play the role of installation. A connecting block 101 is fixedly connected to the bottom end of the carrying and placing plate 2. There are two connecting blocks 101, which are respectively fixed on both sides of the bottom end of the carrying and placing plate 2. A fixing block 102 is fixedly connected between the two connecting blocks 101. A slot is provided on each side of the fixing block 102, and a limiting rod 103 is slidably connected to the inner wall of the slot. The bottom end of the limiting rod 103 is fixedly connected to a base 106, and a disc is provided at the upper end, which can play a role in limiting the fixing block 102. A first spring 104 is connected between the outer wall of the upper end of the limiting rod 103 and the outer wall of the upper end of the fixing block 102, and a second spring 105 is connected between the outer wall of the lower end of the limiting rod 103 and the outer wall of the lower end of the fixing block 102. Therefore, when the carrying and placing plate 2 is vibrated, it will affect the accuracy and stability of the sensor, resulting in inaccurate data. In this regard, when the data acquisition device body 1 on the upper end of the carrying and placing plate 2 is vibrated or impacted, the connecting block 101 and the fixing block 102 at the bottom end of the carrying and placing plate 2 will act the force generated by the vibration on the first spring 104 and the second spring 105, so that the connecting block 101 slides on the outer wall of the limiting rod 103, and then the generated force is relieved. Thus, it is ensured that the data acquisition device body 1 will not be affected by the outside during use. During the sliding process of the connecting block 101, a second limiting block 107 is provided on each side of its outer wall, and the bottom end of the second limiting block 107 is fixedly connected to the upper outer wall of the base 106. The limiting groove 108 provided on one side of the second limiting block 107 fits with the connecting block 101, which can play a role in limiting the connecting block 101 and enable it to slide smoothly on the limiting rod 103 further.

[0030] As Figures 1 to 3 shown, chutes 3 are provided on both sides of the outer wall of the upper end of the carrying and placing plate 2. Sliders 4 are slidably connected to the inner walls of the chutes 3. Clamping blocks 5 are fixedly connected to the outer walls of the upper ends of the sliders 4. There are four clamping blocks 5, and all of them are movably connected to the outer wall of the data acquisition device body 1. A connecting member 6 is fixedly connected to one side of the outer wall of the clamping block 5. A threaded rod 7 is threadedly connected to the inner wall of the connecting member 6. Two first limiting blocks 8 are movably connected to both sides of the outer wall of the threaded rod 7. There are two first limiting blocks 8 on the threaded rod 7, and the bottom ends of the two first limiting blocks 8 are fixedly connected to the outer wall of the upper end of the carrying and placing plate 2, and the two first limiting blocks 8 are close to the chutes 3. A motor 9 is connected to one side of the outer wall of the threaded rod 7. It is characterized in that: there are two threaded rods 7 and a motor 9 is connected to one side of each of them, and both motors 9 are close to one side of the outer wall of the first limiting block 8.

[0031] It should be noted that four clamping blocks 5 are respectively connected to the four sides of the carrying and placing plate 2, and a sliding block 4 is fixedly connected to the bottom end of the clamping block 5. The sliding block 4 is slidably connected to the inner wall of the sliding groove 3 opened on both sides of the upper end of the carrying and placing plate 2. Therefore, the clamping block 5 can slide through the connection between the sliding groove 3 and the sliding block 4, and then adjust the size between the two clamping blocks 5, so as to facilitate clamping data acquisition device bodies 1 of different sizes, making the device practical. The adjustment of the clamping block 5 can be specifically achieved by connecting a connecting piece 6 provided on one side thereof to a threaded rod 7. Positive threads and reverse threads are respectively provided on both sides of the outer wall of the threaded rod 7, and a connecting piece 6 is provided on the outer walls of both the positive threads and the reverse threads. A first limiting block 8 is connected to the outer walls on both sides of the threaded rod 7, which can play a role in limiting the threaded rod 7. A motor 9 is connected to the outer wall of one side of the threaded rod 7 and on the outer wall of the first limiting block 8. Therefore, when the motor 9 is started, the motor 9 can drive the threaded rod 7 to rotate within the first limiting block 8. At this time, affected by the positive threads and reverse threads provided on the outer wall of the threaded rod 7, the connecting pieces 6 respectively connected to its outer wall will move towards each other, and then drive the clamping block 5 on one side thereof to smoothly slide on the inner wall of the sliding groove 3 through the sliding block 4 connected to the bottom end, and drive the clamping block 5 to move towards each other, thereby clamping the data acquisition device body 1 connected to the upper end of the carrying and placing plate 2. This ensures that it will not shift during the vibration process, and can also be adjusted according to data acquisition device bodies 1 of different sizes and dimensions, greatly increasing the practicality of the device.

[0032] The working principle of the above embodiment is as follows: When installing the data acquisition device body 1 on the aircraft, it will be subjected to impacts or vibrations, which will affect the accuracy and stability of the sensor and cause inaccurate data. To solve this problem, the data acquisition device body 1 is placed on the carrying and placing plate 2. After the motor 9 is started, the motor 9 drives the threaded rod 7 to rotate within the first limiting block 8. Due to the positive and reverse threads provided on the outer wall of the threaded rod 7, the connecting piece 6 will move towards each other under the action of the threads, and then drive the clamping block 5 to smoothly slide on the inner wall of the sliding groove 3 through the sliding block 4 connected to the bottom end, so that the clamping block 5 moves towards each other, and finally clamps and fixes the data acquisition device body 1 connected to the upper end of the carrying and placing plate 2. This ensures that the data acquisition device body 1 will not shift during vibration and can be adjusted according to data acquisition device bodies 1 of different sizes. When the data acquisition device body 1 is subjected to vibration or impact, the vibration force is transmitted to the first spring 104 and the second spring 105 through the connecting block 101 and the fixed block 102 at the bottom end of the carrying and placing plate 2, so that the connecting block 101 slides on the outer wall of the limiting rod 103, thereby alleviating the vibration force and ensuring that the data acquisition device body 1 is not affected by the outside during use.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
