Description

Technical Field

[0001] This utility model relates to the field of oil pressure sensor technology, and in particular to a self-cleaning oil pressure sensor interface. Background Technology

[0002] The oil pressure sensor is an important component of the engine lubrication system. It is used to monitor the oil pressure and convert it into an electrical signal so that the electronic control unit can understand the oil pressure status of the engine. It can monitor the oil pressure in the engine lubrication system in real time and ensure that the oil pressure is within the normal range.

[0003] The oil pressure sensor interface is a component that connects the oil pressure sensor to the engine lubrication system. The interface has a pressure transmission channel that is connected to the engine oil passage. The oil acts on the pressure sensing element of the sensor through this channel, enabling the sensor to accurately measure the oil pressure. The channel design must ensure that the oil can flow smoothly while avoiding pressure loss or fluctuations to ensure the accuracy of the sensor measurement.

[0004] Existing sensor interfaces suffer from inadequate structural design, resulting in a delay in the transmission of oil pressure to the sensor's internal sensing element. Excessively long or narrow channel designs hinder oil pressure transmission, affecting the sensor's response speed and preventing timely reflection of engine oil pressure changes. Current solutions involve redesigning the interface channel structure, shortening the channel length, and appropriately increasing the channel diameter to reduce obstruction of oil pressure transmission. Using tapered or streamlined channel designs allows oil to reach the sensor's internal sensing element more quickly, improving response speed. However, the presence of metal debris and dust impurities in the engine oil persists. These impurities accumulate at the sensor interface during oil flow, hindering the oil's proper action on the sensor's pressure sensing element and causing significant measurement errors. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a self-cleaning oil pressure sensor interface, which aims to improve the problem in the prior art where the accumulation of impurities hinders the normal action of oil on the pressure sensing element of the sensor, resulting in large errors in the measurement results.

A sealing block is fixedly connected to the outer wall of the rotating column, and the outer walls of the two sealing blocks are respectively engaged with the left and right front ends of the outer shell.

[0022] 1. In this utility model, by installing a filter plate, particulate impurities contained in the engine oil can be filtered, so that impurity particles will not accumulate in the channel inside the port and cause measurement errors.

Finally, the service life of the port is extended by the fixation of the corrosion-resistant layer. Attached Figure Description

Rotating the connecting column 5 can drive the filter plate 3 to rotate, so that the locking blocks 4 can rotate in the rotating grooves 8 opened at the upper and lower ends of the front side of the inner wall of the outer casing 1, thereby pulling the connecting column 5 and allowing the filter plate 3 to be pulled out, thus realizing the installation or removal of the filter plate 3.

[0034] Reference Figure 1 , Figure 3 and Figure 5 The weather-resistant mechanism 2 includes a pressure-resistant shell 201. The outer wall of the pressure-resistant shell 201 is fixedly connected to the inner wall of the outer shell 1. The pressure-resistant shell 201 can reduce external pressure damage to the port. A silicone sealant layer 203 is fixedly connected to the inner wall of the pressure-resistant shell 201. The silicone sealant layer 203 can improve the sealing performance inside the port.

[0035] Specifically, the outer wall of the pressure-resistant shell 201 is fixed to the inner wall of the outer shell 1 to reduce pressure damage to the port caused by external factors. Subsequently, a silicone sealant layer 203 is connected to the inner wall of the pressure-resistant shell 201, which can improve the sealing performance inside the port. The inner wall of the silicone sealant layer 203 is fixed to the support layer 204. The inner wall of the support layer 204 is provided with multiple fixing rings 205. Each fixing ring 205 is connected to multiple reinforcing strips 206. The combination of fixing rings 205 and reinforcing strips 206 can enhance the internal strength of the port. At the same time, the inner wall of the support layer 204 is also fixed with a corrosion-resistant layer 207, thereby extending the overall service life of the port.

[0036] Reference Figure 1 , Figure 4 and Figure 5The sealing assembly includes two rotating posts 9, the bottom ends of which are rotatably connected to the left and right sides of the inner wall of the outer shell 1, respectively. A sealing block 10 is fixedly connected to the outer wall of the rotating posts 9, and the outer walls of the two sealing blocks 10 are respectively engaged with the left and right front ends of the outer shell 1. The connecting assembly includes a connecting shell 12, the front end of which is fixedly connected to the rear side of the inner wall of the outer shell 1. A threaded groove 13 is provided on the outer wall of the connecting shell 12. A plurality of arc grooves 202 are provided on the outer wall of the pressure-resistant shell 201, and the plurality of arc grooves 202 are all equally spaced.

[0037] Specifically, by rotating the rotating column 9, the sealing block 10 can seal the front side of the rotating groove 8, thereby locking the filter plate 3 and preventing oil from entering the interior of the rotating groove 8. The connection between the connecting shell 12 and the threaded groove 13 makes it easy to flexibly install the port. The multiple arc grooves 202 improve the toughness of the pressure shell 201 and increase its service life.

[0038] Reference Figure 1 , Figure 2 and Figure 3 Multiple protrusions 6 are fixedly connected to the outer wall of the connecting column 5, and the multiple protrusions 6 are all connected in an equidistant ring; sealing rings 11 are fixedly connected to the front and rear sides of the outer wall of the outer shell 1, and the outer walls of the two sealing rings 11 are both designed to be smooth; a rubber sleeve 14 is fixedly connected to the middle of the outer wall of the outer shell 1, and the front and rear sides of the rubber sleeve 14 are respectively fixedly connected between the adjacent two sealing rings 11.

[0039] Specifically, the connection of multiple protrusions 6 increases the static friction of the connecting post 5, thereby improving the anti-slip effect. The sealing ring 11 improves the sealing performance of the port during use, and the rubber sleeve 14 protects the outer wall of the outer casing 1.

[0040] Working principle: A filter plate 3 is installed on the front side of the inner wall of the outer casing 1, which can filter particulate impurities in the oil, prevent impurities from accumulating in the internal channel of the port and affecting sensor detection, and avoid measurement errors. The locking blocks 4 on the upper and lower sides of the filter plate 3 slide and engage with the rotating grooves 8 at the upper and lower ends of the front side of the inner wall of the outer casing 1, thus fixing the filter plate 3. The rotation of the connecting column 5 can drive the filter plate 3 to rotate, so that the locking blocks 4 can rotate in the rotating groove 8, realizing the installation and removal of the filter plate 3. When it is necessary to clean particulate impurities, rotate the connecting column 5 to make the filter plate 3 rotate, and the locking blocks 4 can rotate in the rotating groove 8. Then pull the filter plate 3, and the cleaning ring 7 on its front outer wall will scrape off the particulate impurities attached to the front side of the inner wall of the port, thus completing the self-cleaning of the port. The sealing component can block the front side of the rotating groove 8 to prevent oil from entering. The connecting component can improve the flexibility of port connection and installation.

[0041] Furthermore, the pressure-resistant shell 201 can withstand external pressure, reducing pressure damage to the port. The inner wall of the pressure-resistant shell 201 is connected to a silicone sealant layer 203, which fills gaps and isolates external media, improving the internal sealing performance of the port and preventing liquid leakage. Multiple fixing rings 205 on the inner wall of the support layer 204 and multiple reinforcing strips 206 connected to the inner wall form a three-dimensional support structure, dispersing internal stress and enhancing the overall strength of the port. The inner wall of the support layer 204 is further fixed with a corrosion-resistant layer 207. This layer reduces chemical corrosion by preventing corrosive substances from contacting the internal materials of the port, extending the service life of the port in complex environments, and increasing the weather resistance of the port.
