Abstract
Description
Technical Field
[0001] This utility model relates to the field of sensor technology, and in particular to a high-temperature resistant sensor for automotive electronic throttle valves. Background Technology
[0002] The sensor for the automotive electronic throttle is a core component in the automotive electronic throttle control system. It is used to detect the opening degree and rate of change of the throttle valve and transmit this information to the engine control unit in the form of electrical signals. Based on the received signals, the engine control unit precisely controls the intake air volume of the engine, thereby optimizing parameters such as fuel injection and ignition timing, and achieving more efficient engine operation and more precise vehicle control.
[0003] With the rapid development of the automotive industry, electronic throttle systems have gradually replaced traditional mechanical throttles, becoming the core component of modern automotive engine control. Electronic throttles monitor the throttle opening in real time through sensors and transmit signals to the engine control unit to achieve precise fuel injection and ignition control, thereby improving engine efficiency, power, and emissions performance. However, the working environment of electronic throttles is extremely harsh, especially the sensor part, which needs to withstand harsh conditions such as high temperature and vibration for a long time, leading to a decline in the performance of traditional sensors or even failure. At the same time, the sensor may experience wire connector detachment due to vibration, thus requiring the normal use of the sensor. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0027] Example 1:
[0028] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a high-temperature resistant automotive electronic throttle sensor, including a sensor body 1, a sensor connector 2 on one side of the sensor body 1, a heat dissipation assembly 3 on the top of the sensor body 1, a limiting frame 4 fixed to the bottom of the sensor connector 2, two sets of clamping plates 5 slidably connected to the inner wall of the limiting frame 4, a limiting plate 6 fixed to the top of the sensor body 1, a support plate 7 slidably connected to the inner wall of the limiting plate 6, and a fixing assembly 8 at the bottom of the support plate 7.
[0029] The internal components of the sensor body 1 use high-temperature ceramic capacitors and high-temperature resistant resistors. These components have good thermal stability and electrical performance, and can maintain the accuracy of their parameters at high temperatures. It should be noted that the model of the sensor body 1 is 3517022600. The sensor connector 2 is made of silicone rubber, which can ensure the stability and reliability of signal transmission in high-temperature environments. The heat dissipation component 3 can dissipate the heat generated by the sensor body 1 through its internal structure, thereby improving the high-temperature resistance of the sensor body 1. The limiting frame 4 can limit the clamping plate 5 sliding on its inner wall, and at the same time, it can fix the wire head inserted into the sensor connector 2 by driving the clamping plate 5 through its internal structure, preventing the wire head from falling off the sensor connector 2 during the use of the device. The limiting plate 6 can limit the support plate 7 sliding on its inner wall. The support plate 7 can support the fixing component 8 fixed at its bottom. The two sets of fixing components 8 can fix the wires through their internal structure, preventing the wires from being damaged during the use of the device.
[0030] The heat dissipation assembly 3 includes a housing 31 fixed to the top of the sensor body 1, a heat dissipation strip 32 is provided inside the housing 31, and a number of heat dissipation vents 33 are opened on the inner wall of the housing 31.
[0031] The housing 31 protects the heat sink 32 inside it. The heat sink 32 adopts a combination structure of copper base and aluminum fins. This structure combines the high thermal conductivity of copper and the lightweight of aluminum, which can quickly conduct heat and efficiently dissipate heat. The opening of multiple heat dissipation vents 33 can dissipate the heat generated by the sensor body 1 from different directions, thereby improving the heat dissipation efficiency of the structure.
[0032] Example 2:
[0033] This is the second embodiment of the present invention, which is based on the previous embodiment.
[0034] Specifically, the fixing component 8 includes two sets of snap rings 81 fixed to the bottom of the support plate 7. The inner walls of the two sets of snap rings 81 are provided with a first threaded rod 82 arranged horizontally, and the outer side of the first threaded rod 82 is threadedly connected to the inner wall of the snap ring 81. One end of the first threaded rod 82 is fixed with a handle 83.
[0035] The snap ring 81 consists of two sets of clamping blocks. The first clamping block is fixedly connected to the support plate 7, and the outer side of the second clamping block is rotatably connected to the inner wall of the first clamping block. Since the outer side of the first threaded rod 82 is threadedly connected to the inner wall of both sets of clamping blocks, and a snap ring is threadedly connected to the outer side of one end of the first threaded rod 82, when the handle 83 is turned, the handle 83 can drive the first threaded rod 82 fixed at its axis to rotate. The first threaded rod 82 can drive the two sets of clamping blocks to move. Since a snap ring is threadedly connected to one end of the first threaded rod 82, the first threaded rod 82 cannot be displaced when rotating. Therefore, the second clamping block will move to the outer side of the first threaded rod 82, so that the snap ring 81 can fix the wire connected to the inner wall of the sensor connector 2.
[0036] Specifically, four sets of springs 14 are fixed to the inner wall of the limiting frame 4, and one end of each of the four sets of springs 14 is fixedly connected to one side of the clamping plate 5. A lever 15 is fixed to the top of the clamping plate 5, and the outer side of the lever 15 is slidably connected to the inner wall of the limiting frame 4.
[0037] When it is necessary to fix the connector connected to the inner wall of the sensor connector 2, first push the lever 15 to the right. The lever 15 can drive the clamping plate 5 fixed at its bottom to move. After inserting the connector into the sensor connector 2, release the lever 15. At this time, the clamping plate 5 will be driven by the reverse force of the spring 14 to fix the connector, preventing the connector from falling off during the use of the device.
[0038] Specifically, the inner wall of the limiting plate 6 is threaded with a vertically installed second threaded rod 16, and a turntable 17 is fixed at the top of the second threaded rod 16. The inner wall of the support plate 7 is provided with several sets of threaded holes 18, and the size of the threaded holes 18 is the same as the size of the second threaded rod 16.
[0039] When fixing the wire, first pull the support plate 7 out from the inner wall of the limiting plate 6, adjust the fixing component 8 to the appropriate position, and then rotate the turntable 17. The turntable 17 can drive the second threaded rod 16 fixed at its axis to rotate. The second threaded rod 16 will be inserted into the corresponding threaded hole 18 through the drive of the turntable 17, thereby fixing the support plate 7.
[0040] Example 3:
[0041] This is the third embodiment of the present invention, which is based on the first two embodiments.
[0042] Specifically, four sets of mounting bases 9 are fixed on the outside of the sensor body 1, and the four sets of mounting bases 9 are fixed on both sides of the sensor body 1 in a left-right symmetrical design.
[0043] The symmetrical arrangement of multiple mounting bases 9 allows the sensor body 1 to be installed from different directions, thereby improving the stability of the sensor body 1.
[0044] Specifically, a card interface 10 is provided at the bottom of the sensor body 1, and a sealing ring 11 is provided on the inner wall of the card interface 10.
[0045] The card interface 10 connects the sensor body 1 to the automotive electronic throttle. The sealing ring 11 is made of high-temperature epoxy resin. After high-temperature curing, the high-temperature epoxy resin forms a strong protective layer, which makes the sensor body 1 and the automotive electronic throttle form a strong bond, thereby improving the overall high-temperature resistance of the sensor.
[0046] Specifically, a placement groove 12 is provided at the bottom of the sensor body 1, and a sealing plate 13 is provided on the inner wall of the placement groove 12, with the outer side of the sealing plate 13 fitting into the inner wall of the placement groove 12.
[0047] Since the dimensions of the placement groove 12 match the dimensions of the sealing plate 13, the placement groove 12 can accommodate the sealing plate 13. Furthermore, since the sealing plate 13 is made of the same material as the sealing ring 11, the sensor body 1 can form a strong bond with the electronic throttle valve of the vehicle after it is installed there, thereby improving the overall high-temperature resistance of the sensor.
[0048] When installing the sensor, first place the sensor body 1 on the electronic throttle body of the car, and then use fixing bolts to install the sensor body 1 through the four sets of mounting brackets 9. At this time, since the sealing ring 11 and the sealing plate 13 are made of high-temperature epoxy resin, the high-temperature epoxy resin can form a strong protective layer after high-temperature curing, so that the sensor body 1 and the electronic throttle body of the car form a firm bond, thereby improving the overall high-temperature resistance of the sensor. Then push the lever 15 to the right. The lever 15 can drive the clamping plate 5 fixed at its bottom to move. After inserting the terminal into the sensor connector 2, release the lever 15. At this time, the clamping plate 5 will be driven by the reverse force of the spring 14 to fix the terminal, preventing the terminal from falling off during the use of the device. After the terminal is installed, first remove the support plate 7 from the inner wall of the limiting plate 6. Pull out the fixed component 8 and adjust it to a suitable position. Then rotate the turntable 17. The turntable 17 can drive the second threaded rod 16 fixed at its axis to rotate. The second threaded rod 16 will be inserted into the corresponding threaded hole 18 through the drive of the turntable 17, thereby fixing the support plate 7. Then place the wire in the snap ring 81 and rotate the handle 83. The handle 83 can drive the first threaded rod 82 fixed at its axis to rotate. The first threaded rod 82 drives the snap ring 81 to retract, thereby fixing the wire. In case the wire is damaged, during the use of the sensor body 1, the heat generated by the sensor body 1 is absorbed by the heat sink 32, and then the heat is discharged from different directions through the heat dissipation vents 33 opened on the inner wall of the outer shell 31, thereby improving the heat dissipation efficiency of the structure and thus improving the high temperature resistance of the device.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
