Description

Technical Field

[0001] This utility model relates to the technical field of AMT clutch displacement sensor detection equipment, and in particular to a rapid detection device for AMT clutch displacement sensor. Background Technology

[0002] As a core electrical component of the clutch actuator assembly, the AMT actuator displacement sensor accurately measures the actuator's movement distance, playing a crucial role in the closed-loop control of clutch engagement and disengagement. Typically, this displacement sensor is connected to the TCU (Tracking Control Unit) via the vehicle wiring harness. The TCU detects the signal to control the clutch position. The TCU, connected to the sensor via the vehicle wiring harness, supplies power to the sensor. (See below) Figure 5 As shown, the sensor sends the signal back to the TCU through the vehicle wiring harness. In typical system applications, the TCU reads the sensor signal and sends it to the vehicle's CAN network.

[0003] However, when system-level failures occur, such as the TCU failing to obtain (detect) sensor signals, the entire electrical connection involves three parts: the TCU, the vehicle wiring harness, and the sensors. A failure in any of these three parts can cause the sensor signals to fail to be detected. In particular, the AMT system is part of the vehicle chassis system, making on-site testing and diagnosis inconvenient. When a vehicle malfunctions, there is a need for a quick and effective means to locate the cause of the clutch displacement signal failure. In the current AMT system, when a fault related to the displacement signal occurs, the TCU is used to diagnose the clutch displacement sensor. There is no independent sensor detection device to confirm or eliminate sensor factors. However, when using the TCU for testing, it requires the use of bus testing tools and a computer, which places high demands on the operators and makes the testing process complex and inconvenient.

[0004] In view of this, a rapid detection device for AMT clutch displacement sensor is proposed to solve the above problems. Utility Model Content

[0005] To address the technical problem of inconvenient detection of AMT clutch displacement sensors, this utility model provides a rapid detection device for AMT clutch displacement sensors.

[0006] This utility model is achieved using the following technical solution: A rapid detection device for AMT clutch displacement sensor, comprising a plastic base box, a dual-channel high-precision voltage acquisition and display module installed on one side inside the plastic base box, a wire electrically connected to one side of the dual-channel high-precision voltage acquisition and display module, one end of the wire extending out to the outside of the plastic base box and electrically connected to a male connector, and a portable power supply mechanism provided on the outside of the plastic base box.

[0007] As a further improvement to the above solution, a display screen is installed on the upper side of the dual-channel high-precision voltage acquisition and display module.

[0008] As a further improvement to the above solution, the portable power supply mechanism includes a DC power supply installed on the side of the plastic base box away from the dual-channel high-precision voltage acquisition and display module, and an LDO regulator module installed inside the plastic base box on the side close to the DC power supply. The LDO regulator module is electrically connected to the DC power supply.

[0009] As a further improvement to the above solution, a switch is installed on the outer side of the plastic base box. The switch is electrically connected to the LDO voltage regulator module and to the dual-channel high-precision voltage acquisition and display module.

[0010] As a further improvement to the above solution, a transparent protective shell is fixedly connected to the upper side of the plastic base box.

[0011] As a further improvement to the above solution, when the male connector and the female connector of the displacement sensor to be tested are connected, press the switch to power on the displacement sensor and the dual-channel high-precision voltage acquisition and display module. The display screen lights up, and the values ​​of the two output signals of the displacement sensor are measured and read through the screen. Combined with the current position status of the clutch actuator, the theoretical output value is compared to determine whether the displacement sensor is normal.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model enables rapid detection of displacement sensors on vehicles equipped with AMT systems, thereby improving the efficiency of on-site fault diagnosis. It also has the advantages of small size and portability. 2. When this utility model connects the male connector to the female connector of the displacement sensor to be tested, pressing the switch powers on the female displacement sensor and the dual-channel high-precision voltage acquisition and display module, and the display screen lights up. The values ​​of the two output signals of the displacement sensor are measured and read through the screen, and compared with the current position of the clutch actuator and the theoretical output value, thereby determining whether the displacement sensor is normal. Moreover, this detection device has its own power supply and does not rely on external power supply conditions, so it can carry out fault diagnosis on-site more quickly and efficiently.

Figure 4 As shown, it is paired with the female connector on the displacement sensor on the clutch; Please combine Figure 2 As shown, a display screen 8 is installed on the upper side of the dual-channel high-precision voltage acquisition and display module 7, which allows for direct reading of the readings from the outside. Please combine Figure 1 As shown, the portable power supply mechanism includes a DC power supply 2 installed on the side of the plastic base box 1 away from the dual-channel high-precision voltage acquisition and display module 7; In this embodiment, the DC power supply 2 is a 9V battery, which serves as the main power supply and provides 9V DC voltage to the next-level LDO power module. In order to adapt to the parameters of the 5V LDO regulator module 9 in this example, the power supply is selected as a 9V DC battery, which is small in size and can be integrated into a plastic box, reducing the space occupied and achieving the effect of easy portability. Please combine Figure 2 As shown, an LDO voltage regulator module 9 is installed inside the plastic base box 1 on the side near the DC power supply 2, and the LDO voltage regulator module 9 is electrically connected to the DC power supply 2.
