Furthermore, the controller can realize the function of automatic and smooth turning.

[0004] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0005] First, the current lack of angle sensors on the front axle of tractors prevents the machine's intelligent system from acquiring data such as front axle steering, thus hindering the full performance of some intelligent systems.

[0006] Secondly, the angle sensors currently being retrofitted by users in the market are often modified on existing front axles, resulting in low machining precision, large sensor feedback errors, and high failure rates due to component mismatch.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a steering sensor structure to solve the problems of the lack of angle sensors on the front axle of tractors in traditional technologies, which prevents the intelligent system of the entire machine from acquiring data such as front axle steering; and the low processing precision, large sensor feedback error, and high failure rate of angle sensors modified by users in the market due to the mismatch of components.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A steering sensor structure includes a housing and a steering knuckle. A rotating shaft is fixedly connected to the steering knuckle. A positioning groove is provided on the housing to rub against the inner end of the rotating shaft. A connecting shaft is rotatably inserted into the rotating shaft. The inner end of the connecting shaft is fixed to the positioning groove through a positioning structure. A sensor is fixedly connected to the outer end of the rotating shaft. The detection end of the sensor is fixedly connected to the rotating shaft.

[0011] As an optimized solution, the positioning structure includes an end cap fixed to the bottom surface of the positioning groove, the end cap having a keyway, and the inner end of the connecting shaft having a protrusion that matches the keyway.

[0012] As an optimized solution, the rotating shaft has a central channel, and the connecting shaft is rotatably inserted into the central channel.

[0013] As an optimized solution, the outer end of the rotating shaft is provided with a mounting groove that communicates with the central channel, and the housing end of the sensor is fixed in the mounting groove.

[0014] As an optimized solution, the outer end of the shaft is provided with a connecting section, and a bolt is inserted into the connecting section, which is threadedly connected to the steering knuckle.

[0015] As an optimized solution, a positioning pin is inserted between the end cap and the positioning groove.

[0016] As an optimized solution, the end cap is provided with a pin hole, and the positioning groove is provided with a pin groove that matches the pin hole.

[0017] As an optimized solution, screws are inserted side by side on the end cap, and the positioning groove is provided with a threaded groove that is threaded to the end of the screw.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Because the sensor requires a relative rotational relationship, the steering knuckle and the housing are constrained to the same axis by a rotating shaft, and the steering knuckle and the rotating shaft are fixed by bolts;

[0020] The end cap needs to form a fixed structure with the housing to constrain the rotation of the shaft. The end cap is positioned with the housing by a locating pin.

[0021] The end cap has a keyway that mates with the irregular protrusion at the inner end of the rotating shaft. The rotating shaft has a mounting groove for fixing the sensor. When turning, the housing remains stationary, while the rotating shaft and steering knuckle rotate together, causing the sensor to rotate synchronously. Since the sensor's detection end is connected to the rotating shaft fixed on the housing, the sensor housing and the detection end achieve relative rotation, thereby realizing feedback of the rotation angle. The end cap is positioned using a locating pin to improve transmission accuracy. Attached Figure Description

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0029] like Figures 1 to 4 As shown, the steering sensor structure includes a housing 8 and a steering knuckle 7. A rotating shaft 3 is fixedly connected to the steering knuckle 7. A positioning groove 14 is provided on the housing 8 to rub against the inner end of the rotating shaft 3. A connecting shaft 1 is rotatably inserted into the rotating shaft 3. The inner end of the connecting shaft 1 is fixed to the positioning groove 14 through a positioning structure. A sensor 12 is fixedly connected to the outer end of the rotating shaft 3. The detection end of the sensor 12 is fixedly connected to the rotating shaft 3.

[0030] The positioning structure includes an end cap 5 fixed to the bottom surface of the positioning groove 14, a keyway 9 is provided on the end cap 5, and a protrusion 13 matching the keyway 9 is provided at the inner end of the connecting shaft 1.

[0031] A central channel is provided on the rotating shaft 3, and the connecting shaft 1 is rotatably inserted into the central channel.

[0032] The outer end of the rotating shaft 3 is provided with a mounting groove that communicates with the central channel, and the housing 8 end of the sensor 12 is fixed in the mounting groove.

[0033] The outer end of the shaft 3 is provided with a connecting section, and a bolt 2 is inserted into the connecting section. The bolt 2 is threadedly connected to the steering knuckle 7.

[0034] A positioning pin 6 is inserted between the end cap 5 and the positioning groove 14.

[0035] The end cap 5 has a pin hole 11, and the positioning groove 14 has a pin groove that matches the pin hole 11.

[0036] Screws 4 are inserted side by side on the end cap 5, and a threaded groove 10 is provided on the positioning groove 14 to connect with the threaded end of the screw 4.

[0037] The working principle of this device is as follows:

[0038] Since sensor 12 requires a relative rotational relationship, steering knuckle 7 and housing 8 are constrained to the same axis by rotating shaft 3, and steering knuckle 7 and rotating shaft 3 are fixed by bolt 2;

[0039] The end cap 5 needs to form a fixed structure with the housing 8 to constrain the rotation of the shaft 3. The end cap 5 is positioned with the housing 8 by the locating pin 6.

[0040] The end cover 5 has a keyway 9, which cooperates with the irregular protrusion 13 at the inner end of the rotating shaft 3. The rotating shaft 3 has a mounting groove for fixing the sensor 12. When turning, the housing 8 is fixed, and the rotating shaft 3 and the steering knuckle 7 rotate together, driving the sensor 12 to rotate synchronously. Since the detection end of the sensor 12 is connected to the rotating shaft 3 fixed on the housing 8, the sensor 12 housing 8 and the detection end achieve a relative rotation movement, thereby realizing the feedback of the rotation angle. The end cover 5 is positioned by the positioning pin 6 to improve the transmission accuracy.
