Description

Technical Field

[0001] This utility model relates to the field of throttle position sensor technology, and more particularly to an adaptive automotive throttle position sensor. Background Technology

[0002] The throttle position sensor is used in automotive electronic fuel injection systems. Installed on the throttle body, it converts the throttle opening into an electrical signal and sends it to the ECU (Engine Control Unit) to determine engine operating conditions. Domestically produced cars use over 2 million units per year, and the industry is rapidly expanding. Currently, there are two types of this sensor: digital and analog.

[0003] Existing automotive throttle position sensors on the market are often designed and manufactured based on the specifications of a single type of automotive throttle. Therefore, they can only adapt to the application requirements of that specific type of throttle, presenting significant limitations. Furthermore, due to factors such as manufacturing processes, certain errors inevitably occur at the connection point with the throttle shaft end, and these errors are difficult to adaptively adjust, easily negatively impacting the accuracy of throttle position detection. Utility Model Content

[0004] This utility model relates to an adaptive adjustment automotive throttle position sensor, which solves the problem that existing automotive throttle position sensors are designed based on the production of a single type of automotive throttle, and can only be adapted to the application requirements of this type of automotive throttle. Furthermore, the connection position with the throttle shaft end is affected by processing and has some errors, making it difficult to make adaptive adjustments and easily affecting the accuracy of throttle position detection.

[0005] In a first aspect, this utility model provides an adaptively adjustable automotive throttle position sensor, specifically comprising: a sensor, a toothed seat, bolts, a connecting seat, a U-shaped pin, and tension springs; the sensor internally includes a turntable, the toothed seat is internally connected to the turntable, and the toothed seat is inserted into the shaft end of the throttle; three bolts are internally connected to the turntable; the connecting seat is fixedly connected to the engine and connected to the sensor; a U-shaped pin is externally connected to the sensor, the U-shaped pin is connected to the connecting seat, and two tension springs are externally connected to the U-shaped pin.

[0006] Furthermore, the turntable is provided with a toothed groove inside, and the toothed seat is located in the toothed groove. The teeth on the outside of the toothed seat and the teeth inside the toothed groove mesh with each other. The toothed seat can be replaced according to the different types of throttle shaft ends to meet the adaptation requirements of different types of car throttles. The toothed seat can also be rotated and adjusted according to the position detection accuracy to ensure the accuracy of throttle position detection.

[0007] Furthermore, the turntable has screw holes arranged around its interior, and bolts are threaded into these screw holes. The ends of the bolts contact the outside of the toothed seat. When the toothed seat is connected to the inside of the turntable, the bolts are tightened to fix the toothed seat in place, ensuring a firm connection between the toothed seat and the turntable.

[0008] Furthermore, the sensor has symmetrically arranged sockets inside, and the connector has symmetrically arranged posts outside. The posts are inserted into the sockets, and the sensor and the connector are connected together by the insertion method, making the sensor easier to disassemble and maintain later.

[0009] Furthermore, the sensor is provided with symmetrical guide holes on its exterior, and a U-shaped pin slides through the guide holes.

[0010] Furthermore, the insert has a positioning groove inside, and the end of the U-shaped pin is inserted into the positioning groove.

[0011] Furthermore, the sensor is symmetrically provided with fixed pull holes on its exterior, and the U-shaped pin is symmetrically provided with movable pull holes on its exterior. One end of the tension spring is connected to the fixed pull hole, and the other end of the tension spring is connected to the movable pull hole. When the insertion post is inserted into the insertion hole, the U-shaped pin moves inward under the influence of the tension spring, so that the end of the U-shaped pin is inserted into the insertion hole. The sensor is fixed by the U-shaped pin, ensuring the firmness of the connection between the sensor and the connector.

[0012] This utility model provides an adaptive adjustment automotive throttle position sensor, which has the following beneficial effects:

[0013] In use, the toothed seat can be replaced according to the different types of throttle shaft ends to meet the adaptation requirements of different types of car throttles. The toothed seat can be rotated and adjusted according to the position detection accuracy to ensure the accuracy of throttle position detection. When the toothed seat is connected to the inside of the turntable, the bolts are tightened to fix the toothed seat and ensure the firmness of the connection between the toothed seat and the turntable.

[0014] Furthermore, the sensor is connected to the connector via a plug-in method, making subsequent disassembly and maintenance of the sensor much easier. When the plug is inserted into the socket, the U-shaped pin moves inward under the influence of the tension spring, allowing the end of the U-shaped pin to insert into the socket. The U-shaped pin secures the sensor, ensuring a firm connection between the sensor and the connector. When the sensor malfunctions and needs to be disassembled for repair or replacement, the U-shaped pin is pulled in the opposite direction. The tension spring is gradually stretched, and the end of the U-shaped pin separates from the socket, releasing the sensor from its fixation. This allows the sensor to be removed from the connector, making the operation simpler and more time-saving.

[0029] In this embodiment of the utility model, a toothed groove 1011 is provided inside the turntable 101, and a toothed seat 2 is located inside the toothed groove 1011. The outer teeth of the toothed seat 2 mesh with the inner teeth of the toothed groove 1011. A screw hole 1012 is provided around the inside of the turntable 101, and a bolt 3 is threaded into the screw hole 1012. The end of the bolt 3 contacts the outside of the toothed seat 2.

[0030] By adopting the above technical solution, the toothed seat 2 can be replaced according to the different types of throttle shaft ends to meet the adaptation requirements of different types of car throttles. The toothed seat 2 can be rotated and adjusted according to the position detection accuracy to ensure the accuracy of throttle position detection. When the toothed seat 2 is connected to the inside of the turntable 101, the bolt 3 is tightened to fix the toothed seat 2 and ensure the firmness of the connection between the toothed seat 2 and the turntable 101.

[0031] In Example 2, based on Example 1, the sensor 1 has symmetrically arranged insertion holes 102 inside, and the connecting seat 4 has symmetrically arranged insertion posts 401 outside.
