Description

Technical Field

[0001] This application relates to the field of throttle position sensor technology, and in particular to an automotive throttle position detection sensor. Background Technology

[0002] A throttle position sensor is a device used to detect engine status. It is also called a throttle switch or throttle opening sensor. The main function of the throttle position sensor is to detect whether the engine is idling or under load. Common throttle position sensors mainly consist of a housing, an end cover, a detection circuit, and a metal conductive plate. The detection circuit is installed inside the housing, and the end cover and housing work together to seal and protect the detection circuit.

[0003] While existing throttle position sensors can be used well in daily life, when installed by connecting the cover plate to the top of the sensor, the connection between the cover plate and the sensor is often sealed with a hardened sealing ring. The combination of multiple airbags to soften the connection is not very effective. This results in the hardened sealing ring deforming due to mechanical wear over a long period of use, affecting the sealing performance between the cover plate and the sensor and compromising the safety of the internal components of the sensor. Utility Model Content

[0004] To address the aforementioned issue of inadequate sealing at the joint area due to the combination of multiple airbags for softening, this application provides an automotive throttle position detection sensor.

[0005] The throttle position detection sensor provided in this application adopts the following technical solution: it includes a mounting plate, a sensor body is fixedly connected to the top of the mounting plate, an interface is opened on the surface of the sensor body, a throttle connector is inserted into the inner wall of the interface, a connecting block is fixedly connected to the inner side wall of the sensor body, and a cover plate sleeved on the top of the sensor body is installed on the outer wall of the connecting block.

[0006] A miniature air pump is installed on the side wall of the sensor body, and a first air bladder is provided on the inner side wall of the sensor body. A connecting tube is fixedly connected to the outer wall of the first air bladder, and a second air bladder located below the first air bladder is fixedly connected to one end of the connecting tube.

[0007] A plug rod is fixedly connected to the outer wall of the throttle connector, and a telescopic rod is slidably connected to the top of the interface. One end of the telescopic rod is fixedly connected to a locking block that engages with the outer wall of the plug rod, and a bolt is threadedly connected to the side wall of the interface that slidably connects with the side wall of the throttle connector.

[0008] By adopting the above technical solution, the traditional method of sealing the connection between the cover plate and the sensor by setting a double airbag is changed. Instead, a multi-seal environment formed by the double airbag is used to provide multiple seals for the connection between the cover plate and the sensor. Furthermore, the connection between the sensor and the throttle valve is secured in multiple ways by setting a double locking assembly, thereby improving the sealing performance of the sensor and the stability of the sensor connection, installation and use.

[0009] Preferably, the bottom of the cover plate has a connecting groove that fits onto the top of the sensor body, and the mounting holes on the surface of the cover plate correspond to the mounting holes on the surface of the connecting block.

[0010] By adopting the above technical solution, the effect of pre-shielding and sealing the top of the sensor can be achieved.

[0011] Preferably, the outer wall of the micro air pump is provided with an air delivery pipe that can be detachably connected to the end of the connecting pipe.

[0012] The above technical solution achieves the effect of convenient gas supply and transportation.

[0013] Preferably, the first airbag is connected to the second airbag via a connecting tube.

[0014] By adopting the above technical solution, a multi-layered sealing effect is achieved at the connection between the sensor and the cover plate.

[0015] Preferably, the outer wall of the telescopic rod is fitted with a spring that is fixedly connected to the top of the interface, and one end of the spring is fixedly connected to a pull rod that is fixedly connected to one end of the telescopic rod.

[0016] By adopting the above technical solution, the interface and throttle body connector are initially engaged and installed.

[0017] Preferably, the pressing part of the locking block and the insertion rod is inclined, and the loosening contact part of the locking block and the insertion rod is arc-shaped.

[0018] By adopting the above technical solution, the initial disassembly of the interface and throttle body connector can be achieved.

[0019] Preferably, the side wall of the interface is provided with a nut that is threaded to the outer wall of the bolt, and the connection part between the side wall of the throttle valve connector and the bolt is provided with a groove.

[0020] By adopting the above technical solution, the effect of re-clamping and fixing the interface and connector after initial engagement and installation is improved.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By using a connecting pipe to transport gas, the traditional method of sealing the connection between the cover plate and the sensor by setting a sealing gasket is changed. Instead, a multi-seal environment formed by double airbags is adopted to improve the multi-seal performance of the connection between the cover plate and the sensor.

[0023] 2. By using the engagement of the locking block and the insertion rod, and the connection movement of the bolt and the slot, the connection between the sensor and the throttle valve is secured in multiple ways, improving the sealing performance of the sensor and the stability of the sensor connection, installation and use.

[0031] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0032] This application discloses an automotive throttle position detection sensor.

[0033] Reference Figure 1 , Figure 5 and Figure 6A throttle position detection sensor for automobiles includes a mounting plate 1. A sensor body 2 is fixedly connected to the top of the mounting plate 1. The surface of the sensor body 2 has an interface 3 for connecting to the throttle valve. A throttle valve connector 4 is inserted into the inner wall of the interface 3. A connecting block 5 is fixedly connected to the inner side wall of the sensor body 2. A cover plate 6 for shielding and protecting the top of the sensor body 2 is installed on the outer wall of the connecting block 5. A miniature air pump 7 is installed on the side wall of the sensor body 2. A first airbag 10 is provided on the inner side wall of the sensor body 2. A connecting block 6 is fixedly connected to the outer wall of the first airbag 10. The outer wall of the pipe 9 and the micro air pump 7 is detachably connected to an air supply pipe 8 for convenient gas delivery. One end of the connecting pipe 9 is fixedly connected to a second airbag 11 located below the first airbag 10, and the first airbag 10 is connected to the second airbag 11 through the connecting pipe 9. The outer wall of the throttle body connector 4 is fixedly connected to a plug rod 12. The top of the interface 3 is slidably connected to a telescopic rod 13. One end of the telescopic rod 13 is fixedly connected to a locking block 14 for locking the plug rod 12. The side wall of the interface 3 is threadedly connected to a bolt 18 that is slidably connected to the side wall of the throttle body connector 4.

[0034] Reference Figure 2 and Figure 3 The bottom of the cover plate 6 is provided with a connecting groove for shielding and protecting the top of the sensor body 2, and the mounting holes on the surface of the cover plate 6 are corresponding to the mounting holes on the surface of the connecting block 5, so as to achieve the effect of initial sealing and protection of the top of the sensor during installation and use.

[0035] Reference Figure 3 The outer wall of the telescopic rod 13 is fitted with a spring 15 that is fixedly connected to the top of the interface 3. One end of the spring 15 is fixedly connected to a pull rod 16 for driving the retraction of the locking block 14. The pressing part of the locking block 14 and the insertion rod 12 is inclined, and the loosening contact part of the locking block 14 and the insertion rod 12 is arc-shaped. Through the locking connection of the locking block 14 and the insertion rod 12, the interface 3 and the connector are initially locked and installed for use.

[0036] Reference Figure 2 and Figure 4 The side wall of interface 3 is provided with a nut 17 for driving the bolt 18 to rotate in a limited position. The side wall of the throttle valve connector 4 is provided with a slot 19 at the connection part with the bolt 18. By inserting the bolt 18 into the slot 19, the interface 3 and the connector are initially connected and then reinforced for installation.

[0037] The working principle of this automotive throttle position detection sensor is as follows: According to the sensor's usage position, the mounting plate 1 is installed at the position where the sensor is to be used. After the internal components of the sensor are adjusted, the cover plate 6 is installed on the top of the sensor through the corresponding setting of the mounting holes on the surface of the connecting block 5, so as to initially seal and protect the top of the sensor. The micro air pump 7 is installed on the side wall of the sensor.

[0038] After the miniature air pump 7 is installed, the end of the air supply pipe 8 is connected to one end of the connecting pipe 9 extending to the outside of the sensor, and the miniature air pump 7 is turned on, so that the gas is delivered through the air supply pipe 8 into the connecting pipe 9. The gas is gradually delivered into the first airbag 10 and the second airbag 11, causing the first airbag 10 and the second airbag 11 to gradually inflate. The connection between the cover plate 6 and the sensor is double-sealed by the gas to prevent mechanical wear of the sealing gasket and affect the sealing performance of the connection.

[0039] Next, the throttle body connector 4 is inserted into the interface 3. Under the action of the inclined surface of the pressing part of the insert rod 12 and the locking block 14, the spring 15 will be compressed, and the telescopic rod 13 and the locking block 14 will move away from each other until the contact part of the locking block 14 and the insert rod 12 is flat. At this time, the compressive force on the spring 15 disappears. Under the reaction force of the spring 15 being compressed, the telescopic rod 13 will perform a reset movement. At this time, the locking block 14 will move towards each other, locking and fixing the insert rod 12. After the insert rod 12 and the locking block 14 are initially locked and fixed, the bolt 18 is rotated and the nut 17 limits the bolt 18 so that the bolt 18 is inserted into the slot 19. The connector and interface 3 are double-reinforced for installation and use, which further improves the stability of the installation and use between the sensor and the throttle body.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
