Abstract

This invention relates to the field of sensor technology and discloses a high-temperature sensor with detection and positioning functions. The sensor includes a mounting base, with a heat sink fixedly mounted inside the mounting base and a laser sensor mounted on the outer wall of the mounting base. When a test object in the engine compartment is positioned along the compression path of a folding airbag, the vibration of the test object impacts and compresses the folding airbag. The continuous vibration of the running engine causes a constant change in distance, compressing the outer wall of the folding airbag and causing it to deform. This allows for the delivery of gas, which is then directed and released into the inner cavity of a sealed chamber. This, in turn, drives a cooling impeller, causing it to rotate at the end of the heat sink away from the laser sensor. This creates a temperature difference between the two ends of the heat sink, continuously absorbing and conducting heat from the surrounding area of ​​the laser sensor, ensuring its stable operation.

Description

Technical Field

[0001] This invention relates to the field of sensor technology, specifically to a high-temperature sensor with detection and positioning functions. Background Technology

[0002] A sensor is a device or apparatus that can sense specified measured information and convert it into a usable output signal according to certain rules. It is a core component for detection, control, and data acquisition and is widely used in industrial production, smart devices, automotive electronics, and medical health. In the automotive industry, sensors often need to measure the distance between objects and perform real-time and accurate detection of distance changes of key components in the engine compartment. This is a core link in realizing intelligent engine monitoring and fault early warning.

[0003] When traditional sensors are used to measure distances between objects in the engine compartment, the temperature inside the compartment becomes high as the engine runs. Traditional sensors lack heat dissipation structures, which affects the stable operation and lifespan of the sensors during continuous engine operation, thus affecting the position measurement of some critical components. Even when heat dissipation structures are installed on the sensors to improve heat dissipation efficiency, some technical solutions add electric cooling fans and cleaning air pumps for cooling the sensors and cleaning the laser window, respectively. However, the dual power source design increases the size and weight of the sensors, making it difficult to adapt to the compact installation requirements of the engine compartment.

[0009] As a preferred embodiment of the present invention: the two ends of the outer wall of the drive spring are in contact with the top of the lifting seat and the inner wall of the vent groove, respectively. The inner wall diameter of the vent groove is larger than the outer wall diameter of the lifting seat. The inner cavity of the air guide tube is connected to the inner cavity of the air outlet seat. The lifting seats are installed in the inner cavities of both the air inlet seat and the air outlet seat.

[0010] As a preferred embodiment of the present invention: the inner diameter of the connecting pipe is smaller than the inner diameter of the air guide pipe, and the inner cavity of the connecting pipe communicates with the inner cavity of the sealing chamber; the driving impeller and the heat dissipation impeller are coaxially and fixedly connected; the inner cavity of the fixing pipe communicates with the inner cavity of the sealing chamber; and the installation position of the release seat matches the installation position of the launch window.

[0011] As a preferred embodiment of the present invention: there are two folding airbags, and the two folding airbags are respectively installed on both sides of the outer wall of the mounting base, and the folding airbags are made of hydrogenated nitrile rubber.

[0012] As a preferred embodiment of the present invention: the driving assembly includes a guide seat, a first driving plate is movably sleeved in the inner cavity of the guide seat, a first toothed plate is fixedly mounted on the outer wall of the first driving plate, a second driving plate is rotatably connected to the inner cavity of the guide seat, a second toothed plate is fixedly mounted on the outer wall of the second driving plate, a driving motor is fixedly mounted on the outer wall of the mounting seat, and a driving gear is fixedly mounted on the power output shaft of the driving motor.

[0013] As a preferred embodiment of the present invention: the outer wall of the drive gear meshes with the outer walls of the first gear plate and the second gear plate respectively, and the outer walls of the first drive plate and the second drive plate are connected to the outer walls of the two side folding airbags respectively.

[0015] The present invention has the following beneficial effects: 1. This high-temperature sensor with detection and positioning function utilizes a folded airbag mounted on the outer wall of the mounting base. With the objects to be measured on both sides inside the engine compartment, the distance between them changes continuously due to the engine's vibration. This compression causes the airbag to deform, thereby transporting gas and guiding it into the sealed chamber. This gas then drives the cooling impeller, allowing it to operate at the end of the heat sink away from the laser sensor. This creates a temperature difference between the two ends of the heat sink, enabling the end of the heat sink closer to the laser sensor to continuously absorb heat from its surroundings and dissipate it to the end further away, ensuring the stable operation of the laser sensor.

[0016] 2. This high-temperature sensor with detection and positioning function uses a first drive plate and a second drive plate set on the outer wall of the folded airbag. When there is no significant change in distance between the objects to be measured on both sides, the drive motor is activated. Under the action of the drive motor and the drive gear, the first drive plate and the second drive plate on both sides are driven respectively, thereby compressing the folded airbag. By controlling the rotation direction of the drive motor, the folded airbag is continuously compressed and expanded, thereby continuously delivering gas, which drives the heat dissipation impeller. Under the action of the fixed tube and the release seat, the gas is guided and released, so that the gas acts upward to the outer wall of the emission window, thereby cleaning the outer wall of the emission window and ensuring that the laser sensor can release laser normally to measure distance.

[0019] 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.

[0020] Please see Figures 1-10 A high-temperature sensor with detection and positioning function includes a mounting base 1, a heat sink 2 fixedly mounted in the inner cavity of the mounting base 1, a laser sensor 3 mounted on the outer wall of the mounting base 1, a gas guiding assembly 4 provided on the outer wall of the mounting base 1, a driving assembly 5 provided at the bottom of the mounting base 1, and an emission window 6 fixedly mounted on the outer wall of the laser sensor 3.

[0021] In the above structure, the laser sensor 3 installed on the outer wall of the mounting base 1 can emit infrared laser to the objects to be measured on both sides under the action of the laser sensors 3 on both sides of the outer wall of the mounting base 1, and calculate the time of light reflection back, thereby measuring the distance between the object and the object to be measured. In addition, the heat sink 2 installed in the inner cavity of the mounting base 1 absorbs the heat around the laser sensor 3 under the action of the heat sink 2 and conducts it away from the end away from the laser sensor 3.

[0022] In a preferred embodiment: the air guiding assembly 4 includes a folded airbag 401, a fixing plate 4020 is installed on the outer wall of the folded airbag 401, an mounting plate 4021 is installed on the outer wall of the folded airbag 401, a guide cylinder 402 is installed on the outer wall of the fixing plate 4020, a guide rod 403 is movably sleeved in the inner cavity of the guide cylinder 402, a return spring 404 is installed in the inner cavity of the guide cylinder 402, an air inlet seat 405 is installed at the bottom of the folded airbag 401, an air outlet seat 406 is installed at the top of the folded airbag 401, a venting groove 407 is opened in the inner cavity of the air outlet seat 406, a limit rod 408 is fixedly assembled on the inner wall of the venting groove 407, a drive spring 409 is movably sleeved on the outer wall of the limit rod 408, and a lifting seat 4010 is movably sleeved on the outer wall of the limit rod 408.

[0023] In the above structure, the folded airbag 401 provided on the outer wall of the mounting base 1 causes the distance between the objects to be measured on both sides to change and the objects to be measured on both sides to approach each other, so that the objects on both sides come into contact with the folded airbag 401 and squeeze the folded airbag 401, causing the folded airbag 401 to deform. This causes the guide rod 403 to move inward along the inner wall of the guide cylinder 402 and compress the return spring 404, so that the folded airbag 401 is compressed and deformed between the fixing plate 4020 and the mounting plate 4021, and the space of the inner cavity of the folded airbag 401 is reduced. As the volume of the inner cavity of the folded airbag 401 is compressed, the gas in its inner cavity will push the lifting seat 4010, so that the lifting seat 4010 can move upward along the outer wall of the limiting rod 408 and compress the drive spring 409, thereby making the inner cavity of the folded airbag 401 communicate with the air guide tube 4012, thereby squeezing the gas in the inner cavity of the folded airbag 401 upward into the inner cavity of the air guide tube 4012.

[0024] In a preferred embodiment: the outer wall of the folding airbag 401 is provided with an air guide hole 4011, the top of the air outlet seat 406 is fixedly equipped with an air guide pipe 4012, the end of the air guide pipe 4012 away from the air outlet seat 406 is fixedly equipped with a connecting pipe 4013, the outer wall of the mounting base 1 is equipped with a mounting frame 4014, the outer wall of the mounting frame 4014 is fixedly equipped with a sealing chamber 4015, the inner cavity of the sealing chamber 4015 is rotatably connected to a drive impeller 4016, the inner cavity of the connecting pipe 4013 is rotatably connected to a heat dissipation impeller 4017, the bottom of the sealing chamber 4015 is fixedly equipped with a fixing pipe 4018, and the outer wall of the fixing pipe 4018 is fixedly equipped with a release seat 4019.

[0025] In the above structure, the air guide pipe 4012 provided at the top of the air outlet 406 guides the gas compressed and pushed by the folded airbag 401, so that the gas is released into the inner cavity of the sealed chamber 4015 along the air guide pipe 4012 and the connecting pipe 4013. The gas then drives the drive impeller 4016 to rotate, which in turn drives the heat dissipation impeller 4017 to rotate. The heat dissipation impeller 4017 accelerates the airflow speed on the outer wall of the heat dissipation plate 2, resulting in a lower temperature at the end of the heat dissipation plate 2 away from the laser sensor 3. Thus, the heat dissipation plate 2 continuously conducts heat away from the laser sensor 3, preventing the laser sensor 3 from being affected by the high temperature in the engine compartment and ensuring that the laser sensor 3 can perform normal ranging operations.

[0026] In a preferred embodiment: the outer diameter of the guide rod 403 matches the inner diameter of the guide cylinder 402, the end of the guide rod 403 away from the guide cylinder 402 is connected to the outer wall of the mounting plate 4021, the two ends of the outer wall of the return spring 404 are in contact with the outer wall of the guide rod 403 and the inner wall of the guide cylinder 402 respectively, and the inner cavities of the air inlet seat 405 and the air outlet seat 406 are respectively connected to the inner cavity of the folding airbag 401.

[0027] In the above structure, the guide rod 403, installed in the inner cavity of the guide cylinder 402, can be supported by the return spring 404. The free end of the folding airbag 401 extends to the vibration path of the object under test. When the object under test vibrates, it impacts and squeezes the folding airbag 401, causing it to be compressed. This compresses the folding airbag 401, which in turn pushes the guide rod 403 to move along the inner cavity of the guide cylinder 402, thereby compressing the return spring 404. After the distance between the two objects under test increases, the folding is released. When the folded airbag 401 is compressed, it will be reset and opened by the action of the return spring 404 and the guide rod 403. During the outward expansion of the folded airbag 401, the lifting seat 4010 can block the inner cavity of the air outlet seat 406. However, at this time, the lifting seat 4010 in the inner cavity of the air inlet seat 405 will move upward under the suction of the outward expansion of the folded airbag 401, so that the external air can pass through the air inlet seat 405 and enter the inner cavity of the folded airbag 401, thus replenishing the gas in the inner cavity of the folded airbag 401.

[0028] In a preferred embodiment: the two ends of the outer wall of the drive spring 409 are in contact with the top of the lifting seat 4010 and the inner wall of the vent groove 407, respectively. The inner diameter of the vent groove 407 is larger than the outer diameter of the lifting seat 4010. The inner cavity of the air guide pipe 4012 is connected to the inner cavity of the air outlet seat 406. The lifting seat 4010 is installed in the inner cavities of both the air inlet seat 405 and the air outlet seat 406.

[0029] In the above structure, by providing an air outlet seat 406 and an air inlet seat 405 at the top and bottom of the folding airbag 401 respectively, when the folding airbag 401 is compressed, the air inlet seat 405 is in a closed state and the air outlet seat 406 is in an open state, so that the gas in the inner cavity of the folding airbag 401 is squeezed through the air outlet seat 406 into the air guide tube 4012. When the folding airbag 401 expands outward and resets, the air inlet seat 405 is in an open state and the air outlet seat 406 is in a closed state, thereby allowing external air to enter the inner cavity of the folding airbag 401 to replenish the gas in the inner cavity of the folding airbag 401.

[0030] In a preferred embodiment: the inner diameter of the connecting pipe 4013 is smaller than the inner diameter of the air guide pipe 4012, and the inner cavity of the connecting pipe 4013 communicates with the inner cavity of the sealing chamber 4015; the driving impeller 4016 and the heat dissipation impeller 4017 are coaxially and fixedly connected; the inner cavity of the fixing pipe 4018 communicates with the inner cavity of the sealing chamber 4015; and the installation position of the release seat 4019 matches the installation position of the launch window 6.

[0031] In the above structure, the gas in the inner cavity of the folded airbag 401 is guided by the air guide pipe 4012 through the sealing chamber 4015 set on the outer wall of the mounting frame 4014 and released into the inner cavity of the connecting pipe 4013. Then, under the action of the connecting pipe 4013, the gas is introduced into the sealing chamber 4015, thereby driving the drive impeller 4016, causing the drive impeller 4016 to rotate in the inner cavity of the sealing chamber 4015. As the drive impeller 4016 rotates, the heat dissipation impeller 4017 is driven simultaneously, causing the heat dissipation impeller 4017 to rotate in the inner cavity of the mounting frame 4014, thereby dissipating heat from the end of the heat dissipation plate 2 away from the laser sensor 3, accelerating the air circulation, and thus reducing the temperature of the end of the heat dissipation plate 2 away from the laser sensor 3.

[0032] In a preferred embodiment, there are two folding airbags 401, and the two folding airbags 401 are respectively installed on both sides of the outer wall of the mounting base 1.

[0033] In the above structure, by providing two folding airbags 401 on both sides of the outer wall of the mounting base 1, when the objects to be tested on both sides approach each other, the folding airbags 401 on both sides can be squeezed simultaneously, which can squeeze the gas in the inner cavity of the folding airbags 401 so that more gas can enter the inner cavity of the sealing chamber 4015 to drive the drive impeller 4016 more, so that the drive impeller 4016 rotates in the inner cavity of the sealing chamber 4015. The folding airbags 401 can be made of hydrogenated nitrile rubber, so that the folding airbags 401 can be folded repeatedly.

[0034] In a preferred embodiment: the drive assembly 5 includes a guide seat 501, a first drive plate 502 is movably sleeved in the inner cavity of the guide seat 501, a first toothed plate 503 is fixedly mounted on the outer wall of the first drive plate 502, a second drive plate 504 is rotatably connected to the inner cavity of the guide seat 501, a second toothed plate 505 is fixedly mounted on the outer wall of the second drive plate 504, a drive motor 506 is fixedly mounted on the outer wall of the mounting base 1, and a drive gear 507 is fixedly mounted on the power output shaft of the drive motor 506.

[0035] In the above structure, a first drive plate 502 is provided in the inner cavity of the guide seat 501, and a drive motor 506 is provided on the outer wall of the mounting base 1. The drive motor 506 drives the drive gear 507, which in turn drives the first drive plate 502 and the second drive plate 504 on both sides. This causes the first drive plate 502 and the second drive plate 504 on both sides to move along the inner cavity of the guide seat 501. As a result, the first drive plate 502 and the second drive plate 504 compress the folding airbag 401, actively compressing the volume of the folding airbag 401 and actively squeezing the gas outward from the inner cavity of the folding airbag 401.

[0036] In a preferred embodiment: the outer wall of the drive gear 507 meshes with the outer walls of the first gear plate 503 and the second gear plate 505 respectively, and the outer walls of the first drive plate 502 and the second drive plate 504 are connected to the outer walls of the two side folding airbags 401 respectively.

[0037] In the above structure, the drive gear 507 set on the power output shaft of the drive motor 506 can achieve the driving effect of the drive motor 506. Since the drive gear 507 meshes with the first gear plate 503 and the second gear plate 505 respectively, it can drive the first drive plate 502 and the second drive plate 504 respectively, so that the first drive plate 502 and the second drive plate 504 move along the inner cavity of the guide seat 501, thereby squeezing the outer wall of the folding airbag 401, so as to actively drive the drive impeller 4016 and the heat dissipation impeller 4017, and actively dissipate heat from the end of the heat dissipation plate 2 away from the laser sensor 3.

[0038] In a preferred embodiment: the installation position of the heat sink 2 corresponds to the installation position of the heat sink impeller 4017, and there are two laser sensors 3, which are respectively installed on both sides of the outer wall of the mounting base 1.

[0039] In the above structure, the heat dissipation plate 2 installed in the inner cavity of the mounting base 1 can continuously guide and release external gas through the air inlet seat 405 and the air outlet seat 406 into the inner cavity of the air duct 4012 during the continuous compression and resetting of the folding airbag 401. This drives the drive impeller 4016 and the heat dissipation impeller 4017. As the heat dissipation impeller 4017 rotates, it accelerates the airflow on the outer wall of the heat dissipation plate 2, thereby dissipating heat from the end of the heat dissipation plate 2 away from the laser sensor 3. This creates a temperature difference between the two ends of the heat dissipation plate 2, which in turn continuously dissipates the heat around the laser sensor 3, thus avoiding the long-term effects of the laser sensor 3 being exposed to high temperatures in the engine compartment. Furthermore, the heat dissipation plate 2 can be made of copper, which has good thermal conductivity, facilitating better heat conduction.

[0040] Working principle: During use, the above-mentioned device measures the distance between the two objects to be measured by installing the laser sensor 3 on the outer wall of the mounting base 1. The laser sensor 3 is fixed in the engine compartment, and the free end of its folding airbag 401 extends to the vibration path of the object to be measured. When the object to be measured vibrates, it impacts and compresses the folding airbag 401. When the two objects to be measured approach each other, they can contact and compress the folding airbag 401, causing the folding airbag 401 to deform. This synchronously drives the guide rod 403 to slide inward along the inner wall of the guide cylinder 402 and compresses the return spring 404, thereby causing the folding airbag 401 to move between the fixed plate 4020 and the mounting plate 4021. The compression deformation compresses the inner volume of the folding airbag 401. As the inner volume of the folding airbag 401 continues to decrease, the gas inside the cavity generates a positive thrust, pushing the component lifting seat 4010 upward along the outer wall of the component limiting rod 408 and compressing the component driving spring 409. During this process, the inner cavity of the folding airbag 401 is connected to the air guide pipe 4012, so that the gas in the inner cavity of the folding airbag 401 is forced into the inner cavity of the component air guide pipe 4012. Then, the gas is guided through the air guide pipe 4012 and enters the inner cavity of the sealing chamber 4015 through the connecting pipe 4013, so that the airflow impacts the driving impeller 4016 and makes it rotate, which in turn drives the coaxially connected component heat dissipation impeller 4017 to rotate synchronously. The rotation of the heat dissipation impeller 4017 accelerates the air convection rate on the outer wall of the heat dissipation plate 2, causing a low-temperature area to be formed at the end of the heat dissipation plate 2 away from the component laser sensor 3. Subsequently, based on the thermal conduction characteristics of the component heat dissipation plate 2, the heat around the component laser sensor 3 is continuously conducted outward, reducing the thermal interference of the high temperature environment in the engine compartment on the laser sensor 3 and ensuring the stable operation of the ranging function of the component laser sensor 3. If the objects to be measured on both sides do not approach each other, the drive motor 506 can drive the drive gear 507. Since the drive gear 507 meshes with the first gear plate 503 and the second gear plate 505 respectively, it synchronously drives the first drive plate 502 and the second drive plate 504 to make linear displacement along the inner cavity of the guide seat 501. Through the above transmission structure, an active compressive force can be formed on the outer wall of the component's folding airbag 401. After the inner cavity of the folding airbag 401 is compressed, gas is actively output, thereby driving the component's drive impeller 4016 and cooling impeller 4017 to rotate, ultimately achieving the desired effect. The heat sink 2 has an active heat dissipation function at the end away from the laser sensor 3. When the compressed gas delivery is completed, the gas in the sealed chamber 401 drives the drive impeller 4016 in the inner cavity of the sealed chamber 4015 and continues to be delivered downwards. Under the action of the fixed tube 4018, the gas is guided and delivered to the inner cavity of the release seat 4019. Under the action of the release seat 4019, the gas is guided and released, so that the gas acts on the outer wall of the emission window 6 and has a certain degree of cleaning effect on the outer wall of the emission window 6, ensuring that the laser sensor 3 and the emission window 6 can continuously and stably perform distance detection.
