Description

Technical Field

[0001] The invention relates to the technical field of vehicle throttle valves, in particular to a multifunctional testing system and method for a throttle valve sensor. Background Art

[0002] The throttle is a critical component of a car engine. It acts like the engine's "throat," precisely controlling the flow of air into the engine. Air enters the intake manifold through the throttle, where it mixes with gasoline to form a combustible mixture, which then completes the combustion process and provides power to the engine. The throttle's upper end connects to the air filter, while its lower end connects to the engine block, making its position crucial.

[0003] The throttle position sensor (TPS) is responsible for monitoring the throttle opening. It accurately measures the throttle opening and transmits this data in real time to the engine control unit (ECU). Based on information such as throttle opening and engine speed, the ECU precisely controls the air-fuel ratio, ensuring the engine always operates at the optimal air-fuel ratio. Therefore, the reliability of the throttle position sensor directly determines the accuracy of the engine's air supply, which has a profound impact on engine performance and fuel economy.

[0004] Currently, throttle position sensors are often tested using a multimeter to measure resistance or a simple analog-to-digital (A / D) converter to display voltage. Inspectors must use this data to determine if the sensor is qualified. However, this relatively basic testing method requires a high level of professional expertise. Summary of the Invention

[0047] Reference Figure 1-Figure 4 The basic embodiment of the first aspect of the present invention provides a multifunctional testing system for a throttle sensor, comprising:

[0048] Rack 100;

[0049] The base 200 is provided on the frame 100 and is provided with a first air outlet. The base 200 is used to install a throttle valve.

[0050] The wind mechanism 300 includes a second air outlet and a first power member, and the first power member drives the second air outlet to move toward or away from the base 200;

[0051] The adjustment mechanism 400 includes a turntable and a second power member, wherein the second power member can drive the turntable to move toward or away from the base 200 and drive the turntable to rotate;

[0052] The circuit connection mechanism 500 includes a connector and a third power member, and the third power member can drive the connector to move toward or away from the base 200;

[0053] The marking mechanism 600 includes a marking needle and a fourth power member. The third power member can drive the marking needle to move toward or away from the base 200.

[0054] According to an embodiment of the present invention, by such an arrangement, at least some of the following effects can be achieved: by installing the throttle on the machine base 200, the throttle can be installed and fixed, the first air port is connected to the inlet of one of the valves of the throttle, the air mechanism drives the second air port to connect to the other inlet of the throttle valve, the turntable of the adjustment mechanism 400 can drive the throttle shaft of the throttle to rotate, and the circuit connection mechanism 500 can be connected to the throttle joint through a joint, so that the joint is connected to the internal circuit of the throttle; the throttle shaft is driven to rotate by the adjustment mechanism 400 to simulate the use status of the throttle valve, and its opening is confirmed by the throttle position sensor, and its data is received through the joint to confirm the opening value of the throttle valve. If it is confirmed that its opening value is qualified, a mark is provided by the marking mechanism 600 to confirm that the test is qualified; by providing the wind force of the throttle at the first air port and the second air port, the wind flow state when the throttle is in use can be simulated, and at the same time, the inside of the throttle can be cleaned to ensure product quality.

[0055] It should be noted that the power parts here use common cylinders or motors, which can provide rotational or telescopic power for the device.

[0056] It should be noted that the throttle valve is generally provided with an approximately circular structure, which is connected to the throttle shaft. By rotating the structure, the throttle shaft can be driven to rotate. The adjustment structure in this application drives the throttle shaft to rotate by connecting the structure, and the throttle shaft drives the throttle plate to rotate. The throttle position sensor can sense the position of the throttle plate. The adjustment angle of the throttle plate by the adjustment mechanism 400 is compared with the sensing position of the position sensor to judge the reliability of the position sensor.

[0057] In some embodiments, the first power member includes a first telescopic power member and a first rotating power member. The first rotating power member drives the second air outlet horizontally away from the base 200, and the first telescopic power member drives the second air outlet toward or away from the base 200 in the vertical direction.

[0058] The third power member includes a second telescopic power member and a second rotating power member. The second rotating power member drives the joint away from the base 200 in the horizontal direction, and the second telescopic power member drives the joint toward or away from the base 200 in the vertical direction.

[0059] Under this setting, the rotating power part can drive the second air outlet or connector to rotate, playing a avoidance role and providing space for the installation of the throttle. The telescopic power part drives the second air outlet or connector to slide in the up and down directions so that it can be connected to the throttle.

[0060] In some embodiments, the base 200 is provided with a positioning shaft 210 that can abut the throttle. The first air port can be inserted into the throttle to provide preliminary positioning, and the positioning shaft 210 can abut the throttle. The first air port and the positioning shaft 210 can position two points of the throttle, facilitating installation of the throttle on the base 200.

[0061] In some embodiments, the turntable includes a turntable body and a rotating shaft, wherein the rotating shaft can be eccentrically arranged on the turntable body. The turntable and the throttle shaft are coaxially arranged, and the throttle shaft is driven to rotate by the rotating shaft, so that the throttle plate can rotate.

[0062] In some embodiments, the marking mechanism 600 is further provided with a vibration detection mechanism electrically connected to the marking pin. The vibration detection mechanism can be used to detect the stability of the throttle during operation. For example, throttle shaft eccentricity and internal piping deflection can affect the throttle balance. The vibration detection mechanism can be used to determine product quality.

[0063] In some embodiments, the fourth power member can drive the marking needle to move so that the marking needle just contacts the throttle valve, and the vibration detection structure, marking needle, throttle valve, and frame 100 can form an electrical circuit. When the marking needle just contacts the throttle valve, the vibration detection structure, marking needle, throttle valve, and frame 100 can form an electrical circuit. At this time, the vibration detection structure can output a stable voltage. When the throttle valve is ventilated or the throttle shaft rotates, the throttle valve itself may produce extremely small vibrations, causing the distance between the marking needle and the throttle valve to change, and the voltage thereof will also change. For example, when a small distance is generated between the marking needle and the throttle valve, the voltage will decrease or become 0. Based on this change, the vibration amplitude of the throttle valve can be determined to test the stability of the throttle valve.

[0064] It should be noted that during vibration testing, the marking needle slowly moves toward the throttle valve and stops immediately when it contacts the throttle valve. This operation does not form a dent. During the marking process, the marking needle quickly moves toward the throttle valve, forming a dent on the throttle valve. A small, brightly reflective spot can be seen in the field of view, forming the mark.

[0065] It should be noted that the throttle valve abuts against the inner cavity of the throttle valve through the first air port, and the positioning shaft 210 abuts against the side wall of the throttle valve, which is incomplete positioning.

[0066] A basic embodiment of the second aspect of the present invention provides a multifunctional testing method for a throttle sensor, comprising the following steps:

[0067] Installation and connection: Place the throttle on the base 200, connect the first air outlet to the throttle, install the second air outlet to the throttle through the wind mechanism 300, install the rotary disc to the throttle through the adjustment mechanism 400, and connect the connector to the throttle through the circuit connection mechanism 500;

[0068] Detection: One of the first air outlet and the second air outlet forms a positive pressure, while the other forms a negative pressure. The regulating mechanism 400 regulates the rotation of the driving rotary disk to rotate the throttle shaft of the throttle valve;

[0069] Marking: The marking mechanism 600 drives the marking needle to mark qualified products.

[0070] According to an embodiment of the present invention, by such an arrangement, at least some of the following effects can be achieved: by installing the throttle on the machine base 200, the throttle can be installed and fixed, the first air port is connected to the inlet of one of the valves of the throttle, the air mechanism drives the second air port to connect to the other inlet of the throttle valve, the turntable of the adjustment mechanism 400 can drive the throttle shaft of the throttle to rotate, and the circuit connection mechanism 500 can be connected to the throttle joint through a joint, so that the joint is connected to the internal circuit of the throttle; the throttle shaft is driven to rotate by the adjustment mechanism 400 to simulate the use status of the throttle valve, and its opening is confirmed by the throttle position sensor, and its data is received through the joint to confirm the opening value of the throttle valve. If it is confirmed that its opening value is qualified, a mark is provided by the marking mechanism 600 to confirm that the test is qualified; by providing the wind force of the throttle at the first air port and the second air port, the wind flow state when the throttle is in use can be simulated, and at the same time, the inside of the throttle can be cleaned to ensure product quality.

[0071] In some embodiments, during the installation and connection step, the marking mechanism 600 drives the marking needle toward the throttle valve, causing the marking needle to just contact the throttle valve, thereby forming an electrical circuit among the vibration detection structure, the marking needle, the throttle valve, and the frame 100. The fourth power member can drive the marking needle to move, causing the marking needle to just contact the throttle valve, thereby forming an electrical circuit among the vibration detection structure, the marking needle, the throttle valve, and the frame 100. When the marking needle just contacts the throttle valve, the vibration detection structure, the marking needle, the throttle valve, and the frame 100 can form an electrical circuit. At this time, the vibration detection structure can output a stable voltage. During throttle valve ventilation or throttle shaft rotation, the throttle valve itself may produce extremely small vibrations, causing the distance between the marking needle and the throttle valve to change, and the voltage thereof will also change. For example, when a small distance is generated between the marking needle and the throttle valve, the voltage will decrease or become 0. Based on this change, the vibration amplitude of the throttle valve can be determined to test the stability of the throttle valve.

The specific features, structures, materials or characteristics of several embodiments may be combined in accordance with the principles and purposes of the present invention.

As long as the technical effects of the present invention are achieved by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations to these embodiments within the spirit and principles disclosed in the present invention and without departing from the principles and purpose of the present invention should be included in the scope of protection disclosed in the present invention and should be deemed to fall within the scope of protection of the present invention.
