TECHNICAL FIELD
[0001] The application belongs to the technical field of sensor fixing, and particularly relates to a rocket sensor fixing seat resistant to vibration and high temperature. BACKGROUND
[0002] A rocket model is a miniaturized device that simulates a real space rocket and is usually used for educational, scientific research or entertainment purposes. According to the complexity, it can be divided into two categories: popular / competition model rockets (usually small solid fuel rockets) and engineering research scale models (used for aerodynamic testing). In a rocket model, sensors act as eyes and ears and are the brain connecting the physical world and the control system. They can collect flight state data of the rocket model, ensure the execution of key actions, and ultimately provide the basis for flight analysis. During the flight of the rocket, sensors are the core components for monitoring attitude, overload, temperature and other key parameters, and their working stability directly determines the accuracy and reliability of data acquisition. However, there are two major challenges in the flight process of the rocket model: first, high-frequency vibration generated by the engine and air dynamic disturbance, which can easily cause relative displacement between the sensor and the fixing seat, resulting in data jitter or even sensor falling off; second, high-temperature radiation and heat conduction generated by the engine combustion, which can cause the temperature of the fixing seat to rise sharply, exceeding the tolerance range of the sensor, resulting in performance degradation or permanent damage of the sensor.
[0003] Most existing rocket sensor fixing seats use single rigid fixing or simple rubber buffer structure, which has obvious defects: (1) in terms of vibration resistance, it can only buffer low-frequency vibration in a single direction, has poor damping effect on high-frequency vibration, and the damping direction is single, making it difficult to reduce vibration from both horizontal and vertical directions, thereby failing to adapt to the vibration environment of the rocket model from ignition to recovery; (2) in terms of high temperature resistance, it mostly relies on single heat insulation material wrapping, and the fixing seat itself lacks effective heat dissipation measures, so heat is easily concentrated inside the fixing seat, making it difficult to be discharged in time, thereby causing the sensor to malfunction due to accumulated heat; (3) traditional fixing seats are mostly customized structures, and sensors are usually fixed through threaded connection or other methods, which has poor adaptability and cannot meet the installation requirements of sensors of different sizes. When different types of sensors need to be installed, different fixing seats need to be replaced, thereby increasing the cost. Therefore, the rocket sensor fixing seat resistant to vibration and high temperature provided by the application has important significance for solving the above problems. SUMMARY

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0036] Please refer to Figures 1-7As shown, a vibration-resistant and high-temperature-resistant rocket sensor mounting base of the present invention includes a base 1, which is a cylindrical structure with a closed bottom. Several mounting seats 2 are fixedly connected to the outer wall of the base 1. Each mounting seat 2 has a mounting hole 3, into which fasteners such as screws can be inserted. This allows the base 1, along with the entire mounting base structure, to be rigidly connected to the interior of the rocket model via the mounting seats 2. A fixing frame 4 is fixedly connected to the inner wall of the base 1. The fixing frame 4 is cross-shaped and has a fixed top. The base 1 has several first heat-conducting plates 5 fixedly connected to its inner wall, and several vibration damping grooves 6 are opened on the outer wall of the base 1. Each vibration damping groove 6 is fixedly connected to a vibration damping frame 7, and each vibration damping frame 7 is provided with a first vibration damping component. Several heat-conducting cavities 8 are opened inside the base 1, and a cover plate 9 is installed on the top of the base 1. A second vibration damping component is provided below the cover plate 9, and several second heat-conducting plates 10 are fixedly connected to its bottom surface. Several heat-conducting holes 11 are opened on the surface of the cover plate 9.
[0037] The positioning assembly includes four brackets 12, each fixedly connected to the top of the mounting frame 4 at its bottom. These brackets are arranged symmetrically from left to right and front to back. Each bracket 12 is equipped with an electric telescopic rod 13. A positioning plate 14 is fixedly connected to the end of the output shaft of each electric telescopic rod 13. The electric telescopic rod 13 can have a built-in battery or be electrically connected to a power supply module inside the rocket body. The effective stroke of the electric telescopic rod 13 is 60-120mm. The maximum clamping size (length × width) of the positioning plate 14 is 200 × 150mm, and the minimum clamping size is 50 × 50mm. The clamping force can be adjusted via the current of the electric telescopic rod 13 (5-10A corresponds to 50-100N). The mounting frame 4 can... The system places the sensors required for the rocket model. After placement, the electric telescopic rod 13 can be driven to move the positioning plates 14 toward the sensors until the four positioning plates 14 are tightly pressed against the four sides of the sensors, thus fixing the sensors by clamping. The position of each positioning plate 14 can be adjusted according to the size and model of the sensors to adapt to various types of sensors without the need to replace different fixing base structures, thereby greatly reducing costs. The positioning plates 14 are replaceable and are equipped with rectangular and arc-shaped positioning plate 14 accessories (detachably connected to the electric telescopic rod 13 by bolts). The arc-shaped positioning plate 14 is adapted to circular sensors to meet the clamping requirements of sensors of different shapes.
[0038] The first vibration damping assembly includes a first vibration damping plate 15, which is located on the outside of the vibration damping frame 7. Several first springs 16 are fixedly connected between the inner sidewall of the first vibration damping plate 15 and the outer sidewall of the vibration damping frame 7. A pair of first vibration damping rods 17 are fixedly connected to the inner sidewall of the first vibration damping plate 15. The first vibration damping rods 17 are symmetrically distributed above and below each of the first springs 16, and their ends penetrate the sidewall of the vibration damping frame 7 and are fixedly connected to a movable plate 18. The movable plate 18 is located on the inner side of the vibration damping frame 7, and a 0.5-1mm gap is reserved between the inner side of the movable plate 18 and the inner wall of the base 1. When the base 1 is rigidly connected... When attached to the inside of the rocket model, each of the first damping plates 15 will press tightly against the inner wall of the rocket body under the elastic reset action of the first spring 16. When the rocket model generates horizontal vibration during flight, the vibration will be transmitted to the first damping plate 15 through the rocket body. After being subjected to force, the first damping plate 15 will drive the first damping rod 17 together with the movable plate 18 to move towards the base 1 and compress each of the first springs 16. At this time, the horizontal vibration can be uniformly decomposed by using multiple first springs 16 that are equidistantly linearly distributed, so as to reduce the horizontal low-frequency vibration received by the sensor.
[0039] The second vibration damping assembly includes a second vibration damping plate 19. A second vibration damping rod 20 is fixedly connected to the top center of the second vibration damping plate 19. The top end of the second vibration damping rod 20 passes through the cover plate 9, and a second spring 21 is wound around its body. The top and bottom ends of the second spring 21 are fixedly connected to the bottom of the cover plate 9 and the top of the second vibration damping plate 19, respectively. The second spring 21 is a high-temperature resistant silicone spring. When the cover plate 9 is installed on the top of the base 1, the second vibration damping plate 19 will press tightly against the top of the sensor fixed on the mounting frame 4 under the elastic reset action of the second spring 21. Under the elastic action of the second spring 21, the distance between the second vibration damping plate 19 and the mounting frame 4 can be automatically adjusted according to the different heights of the sensor. When the rocket model generates vertical vibration during flight, the second vibration damping plate 19 will be forced to move the second vibration damping rod 20 towards the cover plate 9 and compress the second spring 21. At this time, the second spring 21 can decompose the vertical vibration to reduce the vertical low-frequency vibration experienced by the sensor, thereby preventing the sensor from bouncing up and down due to vertical vibration.
[0040] The mounting bracket 4 is reinforced with reinforcing ribs 31 on both adjacent side walls. The reinforcing ribs 31 strengthen the mounting bracket 4 and improve its structural strength, thus preventing bending and deformation after prolonged stress, which would affect the stability of the sensor. The top surface of the mounting bracket 4 is provided with several anti-slip pads 22. The anti-slip pads 22 are long strips, and there are four of them. The surface of the anti-slip pads 22 is provided with herringbone anti-slip texture. When the sensor is placed on the mounting bracket 4, each anti-slip pad 22 can be placed on the bottom of the sensor. At this time, the anti-slip texture on the surface of the anti-slip pads 22 can increase the friction between the sensor and the mounting bracket 4, so as to play an anti-slip role, thereby further improving the stability of the sensor after it is fixed, and preventing it from slipping and shifting.
[0041] The positioning plate 14 is rectangular, and its surface is provided with several protective pads 23. The protective pads 23 are rectangular, and their length is equal to the width of the positioning plate 14. The protective pads 23 are equidistantly distributed linearly along the length of the positioning plate 14. The protective pads 23 are made of high-temperature resistant rubber material and are fixed by adhesives or other means. When the sensor is clamped and fixed by the positioning component, the protective pads 23 can be placed between the positioning plate 14 and the side wall of the sensor to play a flexible protection role. Thus, the clamping force applied by the positioning plate 14 directly acts on the side wall of the sensor, causing the sensor to wear or deform.
[0042] The vibration damping grooves 6 are rectangular and are distributed in an equidistant ring along the circumference of the base 1. The vibration damping frame 7 is C-shaped, with a pair of through holes on its surface equal to the diameter of the first vibration damping rods 17. Each first vibration damping rod 17 passes through its corresponding through hole, and the first vibration damping rod 17 and the through hole are in a transition fit with a clearance controlled at 0.1-0.2 mm. The inner wall of the through hole is coated with a high-temperature resistant self-lubricating coating (such as a titanium nitride coating) to prevent vibration deviation. The first springs 16 are high-temperature resistant silicone springs, and each first spring 16 is linearly distributed at equal intervals along the height of the vibration damping frame 7. The multiple equally spaced annularly distributed vibration damping grooves 6 and the first vibration damping components can cover the perimeter of the base 1, so as to evenly disperse the horizontal vibrations received by the base 1 in the surrounding direction, thereby further improving the vibration damping effect.
[0043] The first damping plate 15 is arc-shaped, and its outer wall surface is provided with several first buffer pads 24. The first buffer pads 24 are arc-shaped and are distributed linearly at equal intervals along the height direction of the first damping plate 15. The first buffer pads 24 are made of high-temperature resistant damping silicone material and are fixed by adhesives or other means. The first buffer pads 24 can be placed between the first damping plate 15 and the inner wall of the rocket body. When the first damping plate 15 is subjected to vibration from the horizontal direction, the high-frequency vibration energy can be consumed by the internal friction of the material of the first buffer pads 24. In conjunction with the first damping component, the deviation in the horizontal vibration transmission process can be avoided, thereby achieving full-frequency vibration attenuation in the horizontal direction.
[0044] The first heat-conducting sheet 5 is annular and is equidistantly linearly distributed along the height direction of the base 1. The heat-conducting cavities 8 are equidistantly annularly distributed along the circumference of the base 1, with their top ends penetrating the top of the base 1. Each heat-conducting cavity 8 is filled with a heat-conducting medium, which can be a high-thermal-conductivity silicone grease, and its filling amount is 90%-95% of the volume of the heat-conducting cavity 8. The top opening of the heat-conducting cavity 8 is sealed by a high-temperature resistant sealing plug (such as a ceramic plug). The sealing plug has a 0.5mm vent hole to balance the pressure and prevent the heat-conducting medium from overflowing. The first heat-conducting sheet 5 is made of copper-aluminum alloy material with strong thermal conductivity. The multiple equidistantly linearly distributed first heat-conducting sheets 5 can fully absorb the heat around the sensor and transfer it to the inner wall of the base 1. At this time, the heat-conducting medium in each heat-conducting cavity 8 can absorb the heat from the inner wall of the base 1 and conduct the heat radially to the outside of the base 1 to achieve rapid heat dissipation, thereby effectively preventing heat accumulation around the sensor.
[0045] The base 1 has an outwardly protruding end face at its top opening, which is provided with several positioning holes 25. These positioning holes 25 are evenly distributed in a ring along the circumference of the base 1. The cover plate 9 is circular, and its diameter is equal to the outer diameter of the end face at the top opening of the base 1. Several studs 26 are fixedly connected to the bottom of the cover plate 9. The number of studs 26 is the same as the number of positioning holes 25, and their diameters are equal to the diameters of the positioning holes 25. Furthermore, the central axes of each stud 26 and each positioning hole 25 are located on the same vertical line. Each of the upper parts is threaded with a nut 27 that mates with it. When the cover plate 9 is placed on top of the base 1, each stud 26 can be aligned and pass through the corresponding positioning hole 25. At this time, the nut 27 is threaded onto each stud 26 and tightened. The cover plate 9 and the second vibration damping assembly can be fixed to the top of the base 1 by means of threaded connection. By unscrewing the nut 27, the cover plate 9 and the second vibration damping assembly can be removed from the top of the base 1 to maintain and repair the sensor on the mounting bracket 4 and the various components inside the base 1.
[0046] The second damping plate 19 is circular, and its central axis is on the same vertical line as the central axis of the fixing frame 4. The bottom surface of the second damping plate 19 is provided with a second buffer pad 28, which is also circular and has the same diameter as the second damping plate 19. The second buffer pad 28 is made of high-temperature resistant damping silicone material and is fixed by adhesives or other means. The second buffer pad 28 can be placed between the second damping plate 19 and the top surface of the sensor. When the second damping plate 19 is subjected to vibration from the vertical direction, the high-frequency vibration energy can be consumed by the internal friction of the material of the second buffer pad 28. In conjunction with the second damping component, the offset during the vertical vibration transmission process can be avoided, thereby achieving full-frequency vibration attenuation in the vertical direction.
[0047] The second heat-conducting sheet 10 is rectangular and is distributed in an equidistant ring around the second damping rod 20. The heat-conducting holes 11 are rectangular holes, and their number is the same as that of the second heat-conducting sheet 10. The central axis of each heat-conducting hole 11 and each second heat-conducting sheet 10 are located on the same vertical line. The area of the heat-conducting holes 11 accounts for 60-80% of the area of the second heat-conducting sheet 10. The second heat-conducting sheet 10 is made of copper-aluminum alloy material with strong thermal conductivity and is fixed by welding or other methods. The heat from above the sensor can be fully absorbed by multiple equidistant ring-shaped second heat-conducting sheets 10 and transferred to each heat-conducting hole 11. The surface heat of the second heat-conducting sheet 10 can be quickly diffused to the outside of the base 1 through the heat-conducting holes 11, thereby effectively preventing heat accumulation above the sensor.
[0048] A top cover 29 is provided directly above the cover plate 9. The top of the top cover 29 is arched, and its bottom surface is circular and corresponds to the diameter of the cover plate 9. Several support rods 30 are fixedly connected to the bottom of the top cover 29 and the top of the cover plate 9 by welding. The support rods 30 are distributed in a ring at equal intervals along the circumference of the cover plate 9. The top cover 29 can cover the entire top of the cover plate 9 to play a role in dust protection, thereby preventing dust and other particles from falling in and clogging the heat conduction holes 11 and affecting heat dissipation.
[0049] The circuits, electronic components, and chip modules involved in this invention are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve improvements to the software and methods.
[0050] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the main controller and power supply integrated inside the rocket body, and the main controller is a conventional known device that can play a remote control role.
[0051] The working principle of this invention is:
[0052] In use, the base 1, along with the entire fixed base structure, can be rigidly connected to the rocket body of the rocket model via the mounting base 2 at the bottom of the base 1. Then, the sensors required for the rocket model can be placed on the fixing frame 4 inside the base 1. After placement, the electric telescopic rod 13 can be driven to move the positioning plates 14 towards the sensors until the four positioning plates 14 are tightly pressed against the four side walls of the sensors, thus fixing the sensors by clamping. The position of each positioning plate 14 can be adjusted according to the size and model of the sensors to adapt to various types of sensors without the need to replace different fixed base structures, thereby greatly reducing costs. Finally, the cover plate 9, together with the second vibration damping mechanism, can be fixed to the base 1 via a threaded connection. At the top of the base 1, the second damping plate 19 will press tightly against the top of the sensor fixed on the mounting frame 4 under the elastic reset action of the second spring 21. At the same time, each of the first damping plates 15 will press tightly against the inner wall of the rocket body under the elastic reset action of the first spring 16. When the rocket model generates horizontal vibration during flight, the vibration will be transmitted to the first damping plate 15 through the rocket body. After being stressed, the first damping plate 15 will drive the first damping rod 17 and the movable plate 18 to move towards the base 1 and compress each of the first springs 16. At this time, the vibration in the horizontal direction can be uniformly decomposed by multiple equidistant linearly distributed first springs 16 to reduce the horizontal low-frequency vibration received by the sensor. When the first damping plate 15 is subjected to horizontal vibration... During upward vibration, the high-frequency vibration energy can be dissipated through the internal friction of the material of the first buffer pad 24. Combined with the first damping component, this avoids deviation during horizontal vibration transmission, thus achieving full-frequency vibration attenuation in the horizontal direction. When the rocket model generates vertical vibration during flight, the second damping plate 19, under pressure, will drive the second damping rod 20 towards the cover plate 9 and compress the second spring 21. At this time, the second spring 21 can decompose the vertical vibration, reducing the low-frequency vertical vibration experienced by the sensor, thereby preventing the sensor from bouncing up and down due to vertical vibration. When the second damping plate 19 receives vertical vibration, the high-frequency vibration energy can be dissipated through the internal friction of the material of the second buffer pad 28, combined with the first damping component... The two vibration damping components can avoid deviation during the vertical vibration transmission process, thereby achieving full-frequency vibration attenuation in the vertical direction. Multiple first heat-conducting sheets 5, which are linearly distributed at equal intervals, can fully absorb the heat around the sensor and transfer it to the inner wall of the base 1. At this time, the heat-conducting medium in each heat-conducting cavity 8 can absorb the heat from the inner wall of the base 1 and conduct the heat radially to the outside of the base 1, so as to achieve rapid heat dissipation and effectively prevent heat accumulation around the sensor. In addition, multiple second heat-conducting sheets 10, which are distributed in a ring at equal intervals, can fully absorb the heat above the sensor and transfer it to each heat-conducting hole 11. Through the heat-conducting holes 11, the surface heat of the second heat-conducting sheets 10 can be quickly diffused to the outside of the base 1, thereby effectively preventing heat accumulation above the sensor.
