Description

Technical Field

[0001] The present invention relates to the technical field of sensor equipment, and in particular to a packaging structure of an automobile temperature and pressure integrated sensor and a packaging method thereof. Background Art

[0002] The automotive temperature and pressure sensor is a sensor used to measure the temperature of the coolant in the vehicle engine and the pressure in the cooling system. It is usually installed in the engine tank or cooling system and ensures the normal operation of the engine by monitoring the temperature of the coolant and the system pressure. The sensor can provide real-time temperature and pressure data so that the engine control unit (ECU) can monitor and adjust the performance of the cooling system. When the engine temperature is too high or the pressure in the cooling system is abnormal, the ECU can take corresponding measures, such as adjusting the cooling fan speed or reminding the driver to perform maintenance. It helps prevent engine overheating and cooling system failure, and improve driving safety and reliability.

[0003] Among them, many car owners may choose to temporarily ignore the abnormal signals of the car for various reasons. The above methods may cause damage to the car's temperature and pressure integrated sensor. In severe cases, the vehicle may lose control when running at high speed. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a packaging structure of an automotive temperature and pressure integrated sensor, including a shell mechanism, the shell mechanism also includes a device shell, a plurality of mounting grooves are opened on the side wall of the device shell, and a temperature sensing rod is fixedly connected to the inner wall of the device shell. The mechanism provides an installation position for subsequent mechanisms, and plays a stabilizing effect during operation, ensuring the normal operation of the device and avoiding problems such as bumps.

[0005] The cleaning mechanism includes a sliding tube fixedly connected to the inner walls of the plurality of mounting grooves, a linkage tube is slidably connected to the inner wall of the sliding tube, and a fixed plate is fixedly connected to one end of the linkage tube away from the device housing;

[0006] The control mechanism includes several control boards fixedly connected to the bottom of the device housing, an extrusion spring is fixedly connected to the inner wall of the control board, an extrusion plate is fixedly connected to the end of the extrusion spring away from the control board, and the outer wall of the extrusion plate is slidably connected to the inner wall of the control board.

[0007] Preferably, the shell mechanism also includes a detector fixedly connected to the top central axis of the device shell, a transmission line is fixedly connected to the top of the detector, a fixing plate is fixedly connected to the outer wall of the device shell, and a plurality of air outlets are opened on the top of the fixing plate.

[0008] Preferably, the shell mechanism also includes a plurality of sliding grooves provided on the outer wall of the device shell, a threaded rod is fixedly connected to the bottom of the device shell, and a threaded base is meshedly connected to the outer wall of the threaded rod. The present invention is internally provided with a device shell, a fixing plate, a threaded rod, and a threaded base, and the threaded rod and the threaded base are tightly fitted together, thereby increasing the stability of the device during operation.

[0009] Preferably, the cleaning mechanism also includes an exhaust hole opened on the outer wall of the linkage tube, a reset spring 1 is sleeved on the outer wall of the linkage tube, a sealing plate is connected through one end of the linkage tube away from the fixed disk, a reset spring 2 is fixedly connected to the inner wall of the sealing plate, and a sliding plate is fixedly connected to one end of the reset spring 2 away from the sealing plate, the outer wall of the sliding plate is slidably connected to the inner wall of the sealing plate, and the threaded base is fixed in the desired position before use. When high pressure appears on the detection object, the outward repulsiveness of the high-pressure gas is utilized. After the high-pressure gas reaches the inner wall of the equipment housing through the threaded rod, the high-pressure gas will push the sealing plate and the sliding plate to expand outward. In this process, the linkage tube moves outward along the sliding tube. After the linkage tube expands outward to a certain extent, the sliding tube will lose its blockage of the exhaust hole. At this time, the high-pressure air inside the linkage tube will release pressure outward through the exhaust hole. When the internal pressure is reduced, the linkage tube will pull the fixed disk to reset, thereby realizing autonomous pressure relief of the equipment and extending the service life of the equipment.

[0010] Preferably, the cleaning mechanism also includes a plurality of rollers rotatably connected to the side walls of the temperature sensing rod, a belt is sleeved on the outer wall of the roller, one end of the belt close to the equipment housing is fixedly connected to the inner wall of the sealing plate, and the other end of the belt away from the sealing plate is fixedly connected to a cleaning pipe, the inner wall of the cleaning pipe is slidably connected to the outer wall of the temperature sensing rod, and a spring is fixedly connected to the inner wall of the cleaning pipe. When the above-mentioned pressure relief process is performed, the expansion and contraction of the sealing plate is utilized to drive the belt to move outward. At this time, the belt will be affected by the roller and pull the cleaning pipe at the other end to move downward along the temperature sensing rod and clean the outer wall of the temperature sensing rod, thereby avoiding long-term operation of the temperature sensing rod, which causes dirt to accumulate on the outer wall of the temperature sensing rod and affects the sensing efficiency of the temperature sensing rod. In addition, a reset spring is utilized to restrict the linkage pipe during the pressure relief process, so that the cleaning pipe can repeatedly clean the outer wall of the temperature sensing rod.

[0011] Preferably, the control mechanism also includes a limiting block fixedly connected to the bottom of the extrusion plate, the outer wall of the limiting block is slidably connected to the inner wall of the through hole on the control plate, a fixed bracket is fixedly connected to the side wall of the fixed plate, the end of the fixed bracket away from the fixed plate is fixedly connected to the pulling bracket, and the end of the pulling bracket away from the fixed bracket is rotatably connected to the control column. When the pressure inside the detection object does not decrease, the linkage pipe will push the fixed plate to move outward, and at this time the fixed plate will push the fixed bracket and the pulling bracket to move outward, and force the control column to move outward, and drive the extrusion plate to move downward. At this time, the extrusion plate pushes the limiting block to move downward and contacts the threads outside the threaded base, increasing the friction between the threaded rod and the threaded base, avoiding mechanical bumps and body shaking when the car is running at high speed, causing the threaded rod and the inner wall of the threaded base to loosen, resulting in unstable equipment connection.

[0012] Preferably, the control mechanism also includes a ventilation pipe fixedly connected to the inner wall of the air outlet, a control frame is slidably connected to the inner wall of the sliding groove, one end of the control frame close to the linkage pipe is fixedly connected to the outer wall of the fixed disk, and the end of the control frame away from the fixed disk is slidably connected to the outer wall of the detector. When the pressure is relieved, the fixed plate will collect most of the emitted gas and discharge it outward through the air outlet. At this time, the gas will be discharged to the top of the equipment casing through the ventilation pipe, realizing the autonomous dust removal effect of the equipment. In addition, in the process of the fixed disk moving outward, the control frame will be driven to move outward. At this time, the detector can directly connect to the high pressure value inside the equipment by detecting the length of the control frame. Replacing electronic components with mechanical linkage can effectively avoid numerical deviations of electronic components due to high temperature, high pressure and jitter.

[0013] A packaging structure and method of an automotive temperature and pressure integrated sensor includes the following steps:

[0014] S1: Using the outward repulsiveness of high-pressure gas, the high-pressure gas will push the sealing plate and the sliding plate to expand outward. After the linkage pipe expands outward to a certain extent, the sliding pipe will lose its sealing of the exhaust hole;

[0015] S2: Using the expansion and contraction of the sealing plate, the belt is driven to move outward, pulling the cleaning pipe downward along the temperature sensing rod;

[0016] S3: The linkage tube pushes the fixed plate to move outward, the control column moves outward, and drives the extrusion plate to move downward.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention fixes the threaded base at a desired position before use. When high pressure appears on the detection object, the outward repulsiveness of the high-pressure gas is utilized. After the high-pressure gas reaches the inner wall of the device housing through the threaded rod, the high-pressure gas will push the sealing plate and the sliding plate to expand outward. In this process, the linkage tube moves outward along the sliding tube. After the linkage tube expands outward to a certain extent, the sliding tube will lose its blockage of the exhaust hole. At this time, the high-pressure air inside the linkage tube will be released outward through the exhaust hole. When the internal pressure is reduced, the linkage tube will pull the fixed plate to reset, thereby realizing autonomous pressure relief of the device and extending the service life of the device.

[0019] (2) When the present invention performs the above-mentioned pressure relief process, the expansion and contraction change of the sealing plate is used to drive the belt to move outward. At this time, the belt will be affected by the roller and pull the cleaning tube at the other end to move downward along the temperature sensing rod and clean the outer wall of the temperature sensing rod, thereby avoiding the long-term operation of the temperature sensing rod, which causes the accumulation of dirt on the outer wall of the temperature sensing rod and affects the sensing efficiency of the temperature sensing rod. In addition, the reset spring is used to restrict the linkage tube during the pressure relief process, so that the cleaning tube can repeatedly clean the outer wall of the temperature sensing rod.

[0020] (3) After the present invention completes the above process, if the pressure inside the detection object does not decrease, the linkage tube will push the fixed plate to move outward, and at this time the fixed plate will push the fixed bracket and the pulling bracket to move outward, and force the control column to move outward, and drive the extrusion plate to move downward. At this time, the extrusion plate pushes the limiting block to move downward and contacts the threads outside the threaded base, increasing the friction between the threaded rod and the threaded base, avoiding mechanical bumps and body shaking when the car is running at high speed, causing the threaded rod and the inner wall of the threaded base to become loose, resulting in unstable equipment connection.

[0021] (4) When the present invention is releasing pressure, the fixed plate will collect most of the emitted gas and discharge it outward through the air outlet. At this time, the gas will be discharged to the top of the equipment casing through the ventilation pipe, thereby achieving the autonomous dust removal effect of the equipment. In addition, during the outward movement of the fixed plate, the control frame will be driven to move outward. At this time, the detector can directly connect to the high pressure value inside the equipment by detecting the length of the control frame. By replacing electronic components with mechanical linkage, it can effectively avoid numerical deviations of electronic components due to high temperature, high pressure and jitter.

The threaded rod 109 and the threaded base 110 are tightly fitted together, thereby increasing the stability of the device during operation.

[0039] For example 2, please refer to Figure 4 - Figure 8The present invention is a packaging structure of an automotive temperature and pressure integrated sensor. On the basis of Example 1, the cleaning mechanism 2 also includes an exhaust hole 211 opened on the outer wall of the linkage tube 202, a reset spring 1 204 is sleeved on the outer wall of the linkage tube 202, a sealing plate 205 is connected through one end of the linkage tube 202 away from the fixed disk 203, a reset spring 206 is fixedly connected to the inner wall of the sealing plate 205, a sliding plate 207 is fixedly connected to one end of the reset spring 206 away from the sealing plate 205, and the outer wall of the sliding plate 207 is slidably connected to the inner wall of the sealing plate 205. Before use, the threaded base 110 is fixed at the desired position, and the detection object is fixed on the detection object. When high pressure occurs, the outward repulsiveness of the high-pressure gas is utilized. After the high-pressure gas reaches the inner wall of the device housing 101 through the threaded rod 109, the high-pressure gas will push the sealing plate 205 and the sliding plate 207 to expand outward, wherein the linkage tube 202 moves outward along the sliding tube 201 during this process. After the linkage tube 202 expands outward to a certain extent, the sliding tube 201 will lose its blockage of the exhaust hole 211. At this time, the high-pressure air inside the linkage tube 202 will release pressure outward through the exhaust hole 211. When the internal pressure is reduced, the linkage tube 202 will pull the fixed plate 203 to reset, thereby realizing autonomous pressure relief of the equipment and extending the service life of the equipment.

[0040] The cleaning mechanism 2 also includes a plurality of rollers 208 rotatably connected to the side wall of the temperature sensing rod 103, a belt 209 is sleeved on the outer wall of the roller 208, one end of the belt 209 close to the device housing 101 is fixedly connected to the inner wall of the sealing plate 205, and the end of the belt 209 away from the sealing plate 205 is fixedly connected to a cleaning pipe 210, the inner wall of the cleaning pipe 210 is slidably connected to the outer wall of the temperature sensing rod 103, and a spring is fixedly connected to the inner wall of the cleaning pipe 210. When the above-mentioned pressure relief process is performed, the expansion and contraction of the sealing plate 205 is used to drive the belt 209 The belt 209 moves outward, and at this time, the belt 209 will be affected by the roller 208, and pull the cleaning pipe 210 at the other end to move downward along the temperature sensing rod 103, and clean the outer wall of the temperature sensing rod 103, so as to avoid the long-term operation of the temperature sensing rod 103, which will cause the accumulation of dirt on the outer wall of the temperature sensing rod 103 and affect the sensing efficiency of the temperature sensing rod 103. In addition, the reset spring 204 is used to limit the linkage pipe 202 during the pressure relief process, so that the cleaning pipe 210 can repeatedly clean the outer wall of the temperature sensing rod 103.

[0041] The control mechanism 3 also includes a limiting block 304 fixedly connected to the bottom of the extrusion plate 303, the outer wall of the limiting block 304 is slidably connected to the inner wall of the through hole on the control plate 301, a fixing bracket 309 is fixedly connected to the side wall of the fixing plate 203, the end of the fixing bracket 309 away from the fixing plate 203 is fixedly connected to a pulling bracket 305, and the end of the pulling bracket 305 away from the fixing bracket 309 is rotatably connected to a control column 306. When the pressure inside the detection object does not decrease, the linkage tube 202 will push the fixing plate 203 to move outward, and At this time, the fixing plate 203 will push the fixing bracket 309 and the pulling bracket 305 to move outward, force the control column 306 to move outward, and drive the extrusion plate 303 to move downward. At this time, the extrusion plate 303 pushes the limiting block 304 to move downward and contacts the threads outside the threaded base 110, increasing the friction between the threaded rod 109 and the threaded base 110, avoiding mechanical bumps and body shaking when the car is running at high speed, causing the threaded rod 109 and the inner wall of the threaded base 110 to loosen, resulting in unstable device connection.

[0042] The control mechanism 3 also includes a ventilation pipe 307 fixedly connected to the inner wall of the air outlet 107, and a control frame 308 is slidably connected to the inner wall of the sliding groove 108. The end of the control frame 308 close to the linkage pipe 202 is fixedly connected to the outer wall of the fixed disk 203, and the end of the control frame 308 away from the fixed disk 203 is slidably connected to the outer wall of the detector 104. When the pressure is released, the fixed plate 106 will collect most of the discharged gas and discharge it outward through the air outlet 107. At this time, the gas will be discharged to the top of the equipment housing 101 through the ventilation pipe 307, so as to achieve the autonomous dust removal effect of the equipment. In addition, the process of the fixed disk 203 moving outward will drive the control frame 308 to move outward. At this time, the detector 104 can directly connect to the high pressure value inside the equipment by detecting the length of the control frame 308. By replacing electronic components with mechanical linkage, it can effectively avoid the numerical deviation of electronic components due to high temperature, high pressure and jitter.

[0043] The working process of the automotive temperature and pressure integrated sensor includes the following steps:

[0044] S1: Using the outward repulsiveness of the high-pressure gas, the high-pressure gas will push the sealing plate 205 and the sliding plate 207 to expand outward. After the linkage tube 202 expands outward to a certain extent, the sliding tube 201 will lose its blocking of the exhaust hole 211;

[0045] S2: utilizing the expansion and contraction of the sealing plate 205 to drive the belt 209 to move outward, pulling the cleaning pipe 210 to move downward along the temperature sensing rod 103;

[0046] S2: utilizing the expansion and contraction of the sealing plate 205 to drive the belt 209 to move outward, pulling the cleaning pipe 210 to move downward along the temperature sensing rod 103 .

[0047] A specific application of this embodiment is: before use, the threaded base 110 is fixed at a desired position. When the detection object has high pressure, the high-pressure gas is repelled outward. After the high-pressure gas passes through the threaded rod 109 and reaches the inner wall of the device housing 101, the high-pressure gas pushes the sealing plate 205 and the sliding plate 207 to expand outward. In this process, the linkage tube 202 moves outward along the sliding tube 201. After the linkage tube 202 expands outward to a certain extent, the sliding tube 201 loses its contact with the exhaust hole 211. The high-pressure air in the linkage pipe 202 will be released to the outside through the exhaust hole 211 when the internal pressure is reduced. The linkage pipe 202 will pull the fixed plate 203 to reset. During the pressure relief process, the belt 209 is driven to move outward by the expansion and contraction of the sealing plate 205. At this time, the belt 209 will be affected by the roller 208 and pull the cleaning pipe 210 at the other end to move downward along the temperature sensing rod 103 and clean the outer wall of the temperature sensing rod 103 to avoid the temperature sensing rod 103. 03, the long-term work leads to the accumulation of dirt on the outer wall of the temperature sensing rod 103, which affects the sensing efficiency of the temperature sensing rod 103. In addition, the reset spring 204 is used to limit the linkage pipe 202 during the pressure relief process, so that the cleaning pipe 210 can repeatedly clean the outer wall of the temperature sensing rod 103. If the pressure inside the detection object does not decrease, the linkage pipe 202 will push the fixed plate 203 to move outward, and at this time, the fixed plate 203 will push the fixed bracket 309 and the pulling bracket 305. The control column 306 moves outward and forces the extrusion plate 303 to move downward. At this time, the extrusion plate 303 pushes the limiting block 304 to move downward and contacts the threads outside the threaded base 110, increasing the friction between the threaded rod 109 and the threaded base 110. When the pressure is released, the fixing plate 106 will collect most of the discharged gas and discharge it outward through the air outlet 107. At this time, the gas will be discharged to the top of the equipment housing 101 through the ventilation pipe 307, thereby realizing the autonomous dust removal effect of the equipment.
