[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-2 The present invention provides the following embodiments: A chassis height level sensor includes an injection-molded swing arm 1, a base injection-molded unit 7, and a signal processing unit 4. The top right side of the base injection-molded unit 7 has a movable slot, and an angle measuring shaft is rotatably installed in the movable slot. One end of the injection-molded swing arm 1 is fixedly installed on the angle measuring shaft, and a magnetic unit 3 is installed on the end of the injection-molded swing arm 1 installed on the angle measuring shaft. That is, the magnetic unit 3 is located in the movable slot. The magnetic unit 3 is a magnetic element. The signal processing unit 4 is embedded in the base injection-molded unit 7.

[0019] Specifically, the base injection molding unit 7 includes an injection molding component unit 5, and three evenly distributed contact pins 6 are assembled and connected on the left side of the injection molding component unit 5. The signal processing unit 4 is welded onto the injection molding component unit 5, and the injection molding component unit 5 is embedded in the base injection molding unit 7.

[0020] Specifically, a sealing ring 2 is installed inside the movable slot, and the sealing ring 2 is fitted onto the injection-molded swing arm 1 to seal the interior.

[0021] Specifically, the signal processing unit 4 is a sensing chip, and the magnetic component is a magnet, which is injection molded together with the injection-molded swing arm 1.

[0022] Specifically, the injection-molded swing arm 1 is fixed to the external vehicle, and the height level sensor is press-fitted into the base injection unit 7 by the injection-molded swing arm 1, and is connected and fixed by the injection-molded swing arm 1 and the base injection part hook.

[0023] The specific implementation of this embodiment is as follows: The Hall effect principle is adopted. The signal processing unit 4 is a sensing chip, and the magnetic unit 3 is a magnet, which is injection molded together with the injection molding swing arm 1. The injection molding swing arm 1 is carried by a part on the car and rotates on a plane within a certain angle range. At the same time as it rotates, the magnet below also rotates. Then the magnetic field detected by the sensing chip will change. The sensing chip can calculate the angle or displacement of the motion by detecting this change in the magnetic field. By employing an insert design and a chip welding process for assembly positioning, this design and process can reduce quality defects caused by the final injection-molded product to a certain extent; and it can achieve the required precision using ordinary injection molding equipment. This reduces the manufacturing cost of the part and improves the production quality level.
