[0002] The camshaft position sensor is a sensor used to detect the position of the car's camshaft, also called a synchronous signal sensor. It is a cylinder identification and positioning device. The camshaft position sensor is the most mature Hall-effect sensor technology currently available. Through the Hall effect, the sensor chip collects and outputs signals to the ECU, thereby achieving smooth ignition of the car.

Furthermore, environmental factors such as programming distance (magnetic field strength) can easily lead to errors in camshaft position sensor programming, resulting in inaccurate programming results. Therefore, a programming tool that is compatible with multiple camshaft position sensor models and can control the programming distance is urgently needed. Utility Model Content

[0018] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0019] Example 1

[0020] like Figure 1 and 2As shown, this embodiment provides a programming fixture for a camshaft position sensor. The programming fixture comprises a base 1, a slide rail 2, a mounting plate 3, a support 4, a signal wheel 5, and a micrometer 6. The slide rail 2 is fixed to the base 1, and the mounting plate 3 is slidably mounted on the slide rail 2. A support 4 is provided on one side of the mounting plate 3 and fixed to the base 1. A signal wheel 5 is mounted on the top of the support 4 and rotates around the support 4. The end of the micrometer 6, without an adjuster, passes through the support 4 and is connected to the mounting plate 3. In this embodiment, the slide rail 2 allows the mounting plate 3 to slide within a certain range, restricting relative movement of the mounting plate 3 in the other two directions. The support 4 is used to mount the signal wheel 5, ensuring the position and height of the signal wheel 5, so that the sensor and the signal wheel 5 are aligned at the same height, thereby aligning the centerline of the sensor and the centerline of the signal wheel 5, and avoiding programming errors caused by inadequate programming distance control. In this embodiment, the programming fixture also includes a fixing plate 7, which is mounted at the end of the base 1 and is used to fix the micrometer 6. A spring 8 is mounted on the mounting plate 3, and the other end of the spring 8 is connected to the fixing plate 7. Specifically, micrometer 6 measures the distance between signal wheel 5 and the bottom of the camshaft position sensor, providing programming data for the camshaft position sensor. Spring 8 provides elastic tension between mounting plate 3 and micrometer 6, maintaining close contact between mounting plate 3 and micrometer 6, ensuring that the distance between the camshaft position sensor and signal wheel 5 matches the reading on micrometer 6.

[0021] In this embodiment, mounting plate 3 has a mounting hole 9 at its upper end for mounting a camshaft position sensor. Specifically, mounting hole 9 is used to mount and secure the camshaft position sensor so that the sensor and signal wheel 5 maintain the same height, thereby aligning the sensor's centerline with the signal wheel 5's centerline. This prevents programming errors caused by inadequate programming distance control.

[0022] In this embodiment, the signal wheel 5 includes signal teeth 10, which contact the camshaft position sensor. Specifically, the signal wheel 5 is used for collecting and feeding back signals from the camshaft position sensor. The signal wheel 5 includes slots and signal teeth 10. During programming, the signal teeth 10 of the signal wheel 5 are aligned with the bottom of the camshaft position sensor. The micrometer 6 is adjusted so that the distance between the bottom of the sensor and the signal wheel 5 is at a certain value. The BTPO value at that time is then read. The slots of the signal wheel 5 are then aligned with the bottom of the camshaft position sensor, and the BTPO value at that time is read.

[0023] The present embodiment provides a programming jig for a camshaft position sensor. The utility model provides a programming jig for a camshaft position sensor. The programming jig includes a base, a slide rail, a mounting plate, a pillar, a signal wheel and a micrometer. The base is fixed with a slide rail, and the mounting plate is slidably mounted on the slide rail; a pillar is provided on one side of the mounting plate, and the pillar is fixed on the base; a signal wheel is mounted on the top of the pillar, and the signal wheel rotates around the pillar; the end of the micrometer without an adjuster passes through the pillar and is connected to the mounting plate. The programming jig of the camshaft position sensor of the utility model has a simple structure. The signal wheel and the mounting plate in the programming jig are replaceable to achieve the purpose of being compatible with multiple models of camshaft position sensors. There is no need to frequently adjust the programming parameters, which improves the efficiency of programming the camshaft position sensor. In addition, the programming jig also controls the programming distance by adjusting the micrometer, making the programming of the camshaft position sensor more accurate.

[0024] The working principle of the present utility model is as follows: the programming tool of the camshaft position sensor is placed on a plane, the camshaft position sensor to be programmed is installed in the mounting hole 9 of the mounting plate 3, and electrically connected. Next, the signal tooth 10 of the signal wheel 5 is aligned with the bottom of the camshaft position sensor, the adjuster of the micrometer 6 is rotated to adjust the distance between the bottom of the camshaft position sensor and the signal wheel 5 to 0.2mm, and the BTPO value at this time is read; then the groove of the signal wheel 5 is aligned with the bottom of the camshaft position sensor, and the BTPO value at this time is read. Adjust the micrometer 6 so that the distance between the bottom of the camshaft position sensor and the signal wheel 5 is 1.8mm, and the BTPO value at this time is read. Align the signal tooth 10 of the signal wheel 5 with the bottom of the camshaft position sensor, and read the BTPO value at this time. Calculate and output a 70% programming parameter, align signal tooth 10 of signal wheel 5 with the bottom of the camshaft position sensor, and adjust micrometer 6 so that the BTPO value output by the camshaft position sensor meets the 70% programming parameter. Record the distance between the bottom of the camshaft position sensor and signal wheel 5, as well as the reading of micrometer 6. This completes the entire programming process. To subsequently program other models of camshaft position sensors, simply install the camshaft position sensor to be programmed into the programming fixture, aligning signal tooth 10 of signal wheel 5 with the bottom of the camshaft position sensor, and programming can begin. There is no need to readjust programming parameters, which improves camshaft position sensor programming efficiency.
