Description

Technical Field

[0001] This invention belongs to the field of guidance instrument technology, specifically an inertial guidance instrument with automatic temperature control function. Background Technology

[0002] An inertial navigation system is a precision device that achieves autonomous navigation and positioning based on the principle of inertia. Its core function is to calculate the position, velocity and attitude of an object by measuring its motion parameters (such as acceleration and angular velocity) without relying on external signals. Currently, traditional inertial navigation systems with automatic temperature control mainly rely on the collaborative working mechanism of temperature sensors and heating elements for temperature control. Specifically, the temperature sensor monitors the internal environment of the inertial navigation system and the temperature status of key inertial components such as gyroscopes and accelerometers in real time and accurately. Once the temperature is detected to be lower than the preset ideal operating temperature value, the temperature control circuit will respond quickly and trigger the heating element to start working. The heating element usually adopts the principle of resistance wire heating. Heat is generated by current passing through the resistance wire, thereby raising the internal temperature of the inertial navigation system and ensuring that the inertial components can operate stably in a suitable temperature environment. When the temperature reaches or exceeds the set value, the temperature control circuit will cut off the power supply to the heating element in time, stop the heating process, and prevent the temperature from being too high and damaging the inertial components.

[0003] However, in actual operation, temperature control is required using heating elements. When the heating elements work continuously for a long time, they will be in a high-temperature state. This long-term high-temperature environment will accelerate the aging process of the internal materials of the heating elements, causing changes in their resistance value, reduced heating efficiency, and even serious failures such as broken resistance wires. Once the heating elements age and fail, the temperature control system will no longer be able to effectively control the temperature inside the inertial guide. Summary of the Invention

[0004] To address the problems mentioned in the background section, the present invention provides an inertial guide with automatic temperature control function.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an inertial guidance device with automatic temperature control function, comprising a main body and a power supply unit, and further comprising: Thermal conductive components are installed inside the main body; The heat-conducting component includes a heat-absorbing head fixedly connected inside the main body. A connecting shell is fixedly installed inside the main body. A connecting pipe located inside the connecting shell is fixedly installed on one side of the heat-absorbing head. A rotating block is rotatably connected inside the connecting shell. A pressing wheel is rotatably connected inside the rotating block. A rotating rod is fixedly installed on one side of the rotating block. A motor fixed to the rotating rod is fixedly installed on one side of the outer surface of the connecting shell. A sealing shell is provided inside the main body. A heat-dissipating head fixedly connected to one end of the connecting pipe is rotatably connected inside the sealing shell.

[0006] Preferably, it further includes: A rotating mechanism is disposed inside the sealed shell. The rotating mechanism includes an elastic element fixedly connected to the top of the sealed shell. A rack is fixedly installed at the bottom end of the elastic element. A gear is fixedly installed on one side of the heat dissipation head. A transmission assembly is fixedly installed on the surface of the rotating rod. A cam located at the bottom end of the rack is fixedly installed on one side of the transmission assembly.

[0007] Preferably, it further includes: A sealing assembly is disposed on one side of a sealing shell. The sealing assembly includes a heat exhaust pipe fixedly connected to one side of the sealing shell. A mounting shell is fixedly installed at the top of the heat exhaust pipe. A square shell is fixedly installed inside the mounting shell. A sliding rod is slidably connected inside the square shell. A sealing plate located inside the heat exhaust pipe is fixedly installed at the bottom of the sliding rod. The drive component is located inside the mounting housing.

[0008] Preferably, the drive assembly includes two gears rotatably connected inside the mounting housing. A motor is fixedly mounted on one side of the outer surface of the mounting housing, and the output end of the motor is fixedly connected to one of the gears. A push rod located inside the sliding rod is fixedly mounted on one side of each of the two gears.

[0009] Preferably, a limiting block located on the surface of the connecting pipe is fixedly installed inside the connecting shell, and the extrusion wheel and the limiting block are provided with a gap. The limiting block is designed to be longitudinally symmetrical about the center of the connecting shell.

[0010] Preferably, the connecting tube is made of rubber, and the surface of the connecting tube is in contact with the inner wall of the connecting shell.

[0011] Preferably, the elastic element has a telescopic rod inside, and both ends of the telescopic rod are connected to the elastic element and the rack.

[0012] Preferably, the surface of the push rod is provided with a fixing hole, and the sliding rod located inside the push rod is designed to be circular.

[0013] Preferably, both the square shell and the sliding rod have limiting holes on their surfaces, and the pushing rod can slide inside the limiting holes.

[0014] Preferably, the surface of the extrusion wheel is provided with a rubber sleeve, and there are three extrusion wheels arranged in an array on the surface of the rotating block.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention drives a motor to rotate a rotating rod, which in turn drives a rotating block and a pressing wheel to rotate synchronously. During rotation, the pressing wheel rubs against the connecting pipe, causing it to roll. This rolling action applies pressure to the surface of the connecting pipe, causing it to deform. Since the connecting pipe is connected to a heat-absorbing head, the deformation triggers the heat-absorbing head to generate suction, absorbing the heat generated by the power supply. The heat is conducted through the connecting pipe and then ejected from the heat exhaust head, forming a directional heat flow that blows towards the surfaces of the gyroscope and accelerometer. Ultimately, by utilizing the heat generated by the power supply and driving the motor to press the surface of the connecting pipe with the pressing wheel, the heat is guided to the surfaces of the gyroscope and accelerometer, ensuring that the gyroscope and accelerometer reach and maintain a suitable operating temperature range. This guarantees the normal operation of the gyroscope and accelerometer and improves the overall performance of the navigation system. This invention utilizes a rotating rod to drive a linkage transmission assembly, which in turn drives a cam located at the bottom of a rack to rotate synchronously. The interaction between the cam and the bottom of the rack generates a pushing force, causing the rack to move upward. During this process, the tightly connected elastic element is compressed. When the cam moves away from the bottom of the rack, the elastic element, due to its restorative property, pushes the rack downward, achieving reciprocating movement of the rack. The rack meshes with a gear, and its movement drives a gear to reciprocate. The gear then drives the heat exhaust head to complete its reciprocating rotation. Finally, through the linkage transmission assembly of the rotating rod, the rack drives the heat exhaust head to reciprocate. This reciprocating rotation greatly increases the range of hot air jets from the heat exhaust head, allowing heat to be distributed more widely and evenly, thereby providing more sufficient heat protection for related components. This invention uses a second drive motor to rotate a second gear. The two gears rotate synchronously and drive two push rods to rotate inside a sliding rod. The rotation of the push rods generates axial thrust, forcing the sliding rod to move linearly along the inner wall of the square shell. During the movement, the sliding rod pulls the sealing plate upward, releasing the seal on the exhaust channel heat pipe. At this time, the high-temperature gas accumulated inside the sealed shell forms a directional airflow through the heat pipe and is quickly discharged to the external space. Finally, the second drive motor causes the second gear to drive the sealing plate to release the seal on the heat pipe, realizing the timely discharge of hot gas inside the sealed shell. This effectively avoids the performance degradation or even damage of the gyroscope and accelerometer due to excessive temperature. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, the present invention provides an inertial guidance device with automatic temperature control function, including a main body 100 and a power supply 200, and further including: A heat-conducting component 300 is installed inside the main body 100; The heat-conducting component 300 includes a heat-absorbing head 301 fixedly connected inside the main body 100. A connecting shell 303 is fixedly installed inside the main body 100. A connecting pipe 302 located inside the connecting shell 303 is fixedly installed on one side of the heat-absorbing head 301. A rotating block 304 is rotatably connected inside the connecting shell 303. A pressing wheel 305 is rotatably connected inside the rotating block 304. A rotating rod 306 is fixedly installed on one side of the rotating block 304. A motor 307 fixed to the rotating rod 306 is fixedly installed on one side of the outer surface of the connecting shell 303. A sealing shell 308 is provided inside the main body 100. A heat-dissipating head 309 fixedly connected to one end of the connecting pipe 302 is rotatably connected inside the sealing shell 308.

[0020] Using the above scheme: The operator installs the main body 100 in the designated position. During the operation of the main body 100, heat will appear on the surface of the power supply unit 200, which will drive the motor 307 to rotate, thereby rotating the rotating rod 306. The rotation of the rotating rod 306 will sequentially drive the rotating block 304 and the extrusion roller 305 to rotate. During the rotation of the extrusion roller 305, the friction between it and the connecting pipe 302 causes the extrusion roller 305 to begin rolling. During this rolling process, the extrusion roller 305 will apply pressure to the surface of the connecting pipe 302. After being compressed, the connecting pipe 302 will undergo a certain degree of deformation. Since the connecting pipe 302 is connected to the heat absorption head 301, this deformation will cause the heat absorption head... 301 generates suction, which allows the heat-absorbing head 301 to absorb the heat generated by the power supply unit 200. After the heat is absorbed, it passes through the connecting pipe 302 and is finally ejected from the heat-dissipating head 309. The heat is blown onto the surfaces of the gyroscope and accelerometer, thereby heating them to ensure the overall performance of the navigation system. Finally, by utilizing the heat generated by the operation of the power supply unit 200 and driving the motor 307 to make the extrusion wheel 305 press against the surface of the connecting pipe 302, the heat is guided to the surfaces of the gyroscope and accelerometer, enabling the gyroscope and accelerometer to reach and maintain a suitable operating temperature range, ensuring the normal operation of the gyroscope and accelerometer, and improving the overall performance of the navigation system.

[0021] like Figure 6 As shown, it also includes: The rotating mechanism 400 is located inside the sealing shell 308. The rotating mechanism 400 includes an elastic element 401 fixedly connected to the top of the inside of the sealing shell 308. A rack 402 is fixedly installed at the bottom end of the elastic element 401. A gear 403 is fixedly installed on one side of the heat dissipation head 309. A transmission assembly 404 is fixedly installed on the surface of the rotating rod 306. A cam 405 located at the bottom end of the rack 402 is fixedly installed on one side of the transmission assembly 404.

[0022] The above solution is adopted: Through the design of the rotating mechanism 400, when the rotating rod 306 rotates, the linkage transmission component 404 rotates, and the transmission component 404 drives the cam 405 to rotate together. Since the cam 405 is located at the bottom end of the rack 402, during the rotation of the cam 405, its interaction with the bottom end of the rack 402 generates a pushing force, causing the rack 402 to begin to move upward. During the movement of the rack 402, the elastic element 401, which is closely connected to it, is gradually compressed. When the cam 405 moves away from the bottom end of the rack 402, the elastic element 401 will recover due to its restorative property. The rack 402 is pushed down, thereby realizing the reciprocating movement of the rack 402. The rack 402 meshes with the gear 403. The moving rack 402 drives the gear 403 to reciprocate. The rotation of the gear 403 further transmits power, ultimately driving the heat exhaust head 309 to reciprocate. Finally, through the linkage of the rotating rod 306 and the transmission assembly 404, the rack 402 drives the heat exhaust head 309 to reciprocate. This reciprocating rotation greatly increases the hot air injection range of the heat exhaust head 309, allowing the heat to be distributed more widely and evenly, thereby providing more sufficient heat protection for related components.

[0023] like Figure 7 and Figure 8 As shown, it also includes: A sealing assembly 500 is disposed on one side of a sealing shell 308. The sealing assembly 500 includes a heat exhaust pipe 501 fixedly connected to one side of the sealing shell 308. A mounting shell 502 is fixedly installed at the top of the heat exhaust pipe 501. A square shell 503 is fixedly installed inside the mounting shell 502. A sliding rod 504 is slidably connected inside the square shell 503. A sealing plate 505 located inside the heat exhaust pipe 501 is fixedly installed at the bottom of the sliding rod 504. The drive component 600 is located inside the mounting housing 502.

[0024] like Figure 7 and Figure 8 As shown, the drive assembly 600 includes a second gear 601 rotatably connected inside the mounting housing 502, and there are two gears 601. A second motor 603 is fixedly installed on one side of the outer surface of the mounting housing 502, and the output end of the second motor 603 is fixedly connected to one of the gears 601. A push rod 602 located inside the sliding rod 504 is fixedly installed on one side of each of the two gears 601.

[0025] Using the above scheme: Through the design of the sealing component 500 and the driving component 600, when the internal temperature of the sealing shell 308 is higher than the specified temperature, the second motor 603 will be driven. Then, the second motor 603 drives the second gear 601 to rotate. Since there are two meshing gears 601, the rotating gear 601 will drive the other gear 601 to rotate synchronously, just like a gear transmission. Subsequently, these two gears 601 simultaneously drive the two push rods 602 to rotate inside the sliding rod 504. The rotation of the push rods 602 will drive the sliding rod 504 to rotate within the square shell 504. 03. Internal movement: As the sliding rod 504 moves, it pulls the sealing plate 505 upward, thereby removing the blockage on the heat exhaust pipe 501. The hot air accumulated inside the sealing shell 308 then has an outlet to be released, quickly entering the heat exhaust pipe 501 and being discharged to the outside of the main body 100. Finally, through the drive motor 603, the gear 601 drives the sealing plate 505 to remove the blockage on the heat exhaust pipe 501, realizing the timely discharge of hot air inside the sealing shell 308. This effectively avoids the gyroscope and accelerometer from experiencing performance degradation or even damage due to excessive temperature.

[0026] like Figure 3 and Figure 4 As shown, a limiting block 701 is fixedly installed inside the connecting shell 303 on the surface of the connecting tube 302, and there is a gap between the extrusion wheel 305 and the limiting block 701. The limiting block 701 is longitudinally symmetrical about the center of the connecting shell 303. The connecting tube 302 is made of rubber, and the surface of the connecting tube 302 is in contact with the inner wall of the connecting shell 303.

[0027] The above solution employs the following design: The limiting block 701, fitted onto the connecting pipe 302, provides precise positioning, effectively preventing displacement of the connecting pipe 302 under stress. Furthermore, the gap between the extrusion wheel 305 and the limiting block 701 prevents interference with the rotation of the extrusion wheel 305. The limiting block 701 also features a mirror design, providing stable support for the connecting pipe 302 from multiple directions. The connecting pipe 302, made of rubber, is designed to withstand repeated compression without easily breaking or damaging itself, significantly increasing its lifespan. Additionally, during the rotation of the heat dissipation head 309, the connecting pipe 302, with its rubber material's flexibility and elasticity, adapts well to the dynamic changes caused by the rotation of the heat dissipation head 309, maintaining a stable shape and preventing obstruction of the normal heat transfer.

[0028] like Figure 6 and Figure 8As shown, the elastic element 401 has a telescopic rod inside, and both ends of the telescopic rod are connected to the elastic element 401 and the rack 402. The surface of the push rod 602 has a fixing hole, and the sliding rod 504 located inside the push rod 602 has a circular design.

[0029] The above solution is adopted as follows: Through the design of the elastic element 401, when the elastic element 401 is compressed, the internal telescopic rod will contract synchronously when the elastic element 401 is compressed by external force. During the dynamic process of compression and deformation of the elastic element 401, the relative position of the elastic element 401 is always kept stable, which effectively avoids the position of the elastic element 401 from shifting due to uneven force or external interference when it is compressed, and ensures the stability of the rack 402 movement. Through the design of the push rod 602, since the surface of the push rod 602 has a fixing hole, the sliding rod 504 can slide inside the push rod 602 when the push rod 602 moves. The sliding rod 504 inside the push rod 602 is circular, which ensures that the sliding rod 504 can slide smoothly on the push rod 602.

[0030] like Figure 2 , Figure 3 and Figure 8 As shown, both the square shell 503 and the sliding rod 504 have limit holes on their surfaces, and the push rod 602 can slide inside the limit holes. The surface of the extrusion wheel 305 is provided with a rubber sleeve. There are three extrusion wheels 305, which are arranged in an array on the surface of the rotating block 304.

[0031] The above solution employs the following design: The square shell 503 and sliding rod 504 slide within the limiting hole during the rotation of the push rod 602. This ensures that the square shell 503 and sliding rod 504 do not interfere with the rotation of the push rod 602. Furthermore, the surface of the push rod 602 is in contact with the inner wall of the limiting hole, thus limiting the rotation of the push rod 602 and ensuring its stability. The extrusion wheel 305, with its rubber sleeve, effectively buffers the impact force while extruding the surface of the connecting tube 302, preventing scratches, dents, and other damage to the surface of the connecting tube 302 due to direct force. Therefore, even under frequent extrusion operations, the connecting tube 302 maintains a good appearance and performance.

[0032] Working principle and usage process of this invention: The operator installs the main body 100 in the designated position. During the operation of the main body 100, heat will appear on the surface of the power supply unit 200. Then, the drive motor 307 will cause the rotating rod 306 to rotate. The rotating rod 306 will drive the rotating block 304 and the extrusion wheel 305 to rotate in sequence. Then the extrusion wheel 305 will start to roll. During the rolling process, the extrusion wheel 305 will apply pressure to the surface of the connecting pipe 302. After being extruded, the connecting pipe 302 will deform to a certain extent. During the deformation process, the heat absorption head 301 will start to absorb the heat generated by the power supply unit 200. After the heat is absorbed, it will pass through the connecting pipe 302 and finally be ejected from the heat exhaust head 309. The heat will be blown towards the surface of the gyroscope and accelerometer, thereby heating them to ensure the overall performance of the navigation system. When the rotating rod 306 rotates, the linkage transmission assembly 404 and the cam 405 rotate. During the rotation of the cam 405, the rack 402 begins to move upward. During the movement of the rack 402, the elastic element 401 closely connected to it is gradually compressed. Utilizing the restorative property of the elastic element 401, the rack 402 reciprocates. Then, the moving rack 402 drives the gear 403 to reciprocate. The rotation of the gear 403 further transmits power, ultimately driving the heat dissipation head 309 to reciprocate. When the internal temperature of the sealed shell 308 exceeds the specified temperature, the second motor 603 is driven, which in turn drives the two gears 601 to rotate. The two gears 601 simultaneously drive the two push rods 602 to rotate inside the sliding rod 504. The rotation of the push rods 602 causes the sliding rod 504 to move inside the square shell 503. As the sliding rod 504 moves, it pulls the sealing plate 505 upward, thereby removing the blockage on the heat dissipation pipe 501. The hot air accumulated inside the sealed shell 308 then has an outlet to be released, quickly entering the heat dissipation pipe 501 and being discharged to the outside of the main body 100. This effectively prevents the gyroscope and accelerometer from experiencing performance degradation or even damage due to excessive temperature, and finally completes the operation process.
