The sensor body is provided with a signal shaft that senses and generates an electrical signal when rotating. The signal shaft is connected to the swing arm. It also includes a connecting rod, a threaded sleeve, a universal sleeve, a screw, and a ball head screw. The connecting rod is integrally injection molded and is provided with a main rod and an upper mounting head and a lower mounting head that are rotatably distributed at both ends of the main rod. The upper mounting head and the lower mounting head are respectively embedded with a threaded sleeve and a universal sleeve. The swing arm is threadedly connected with a screw that matches the threaded sleeve. One end of the connecting rod is rotatably connected to the swing arm through the threaded sleeve, and the other end is hinged to a ball head screw through the universal sleeve.

[0004] The above technical solution uses a hybrid material of nylon and glass fiber for the main body of the connecting rod. The connecting rod is integrally injection molded on the basis of the threaded sleeve and universal sleeve, which has strong mechanical strength and corrosion resistance. It replaces the traditional metal connecting rod and bushing combination structure, reduces the overall weight of the sensor, and can effectively resist the erosion of harsh environments such as water, salt, and oil.

[0005] The present invention is further configured such that the upper mounting head or the lower mounting head has a cylindrical part and a transition part, the threaded sleeve or universal sleeve is coaxially distributed in the cylindrical part, the main rod is obliquely distributed in the cylindrical part through the transition part, and the axis of the threaded sleeve is parallel to the axis of the universal sleeve.

[0006] Furthermore, the ball head screw includes an external hexagonal portion, a spherical portion, and a stud portion from top to bottom. The universal joint is provided with a spherical groove that matches the spherical portion, and the ball head screw is hinged to the connecting rod through the spherical groove.

[0007] Using the above technical solution, during installation, the sensor body is mounted on the vehicle body, and the connecting rod is connected to the suspension connecting rod via ball head screws. Through the hinge between the ball head screws and the connecting rod, the installation error between the vehicle body and the suspension connecting rod can be automatically compensated, eliminating the problem of connecting rod bending caused by installation stress.

[0008] The present invention is further configured such that the cylindrical portion is provided with a mounting hole, and the outer surface of the threaded sleeve and the universal sleeve is provided with annular teeth for embedding into the mounting hole.

[0009] By adopting the above technical solution, the contact area between the threaded sleeve or universal sleeve and the cylindrical part is increased by the ring tooth, and an interlocking structure that resists pull-out is formed to avoid the phenomenon of the insert loosening or falling out.

[0010] The present invention is further provided that there are staggered triangular ribs one and two between the cylindrical part and the transition part, and both triangular ribs one and two are smoothly connected to the cylindrical part.

[0011] Using the above technical solution, two sets of triangular ribs one and two sets of triangular ribs two are distributed in a cross shape at the junction to enhance the bending strength of the upper / lower mounting head.

[0012] The present invention is further configured such that the two ends of the main rod are provided with rectangular portions and reinforcing ribs connecting adjacent rectangular portions, the reinforcing ribs being distributed in a cross shape around the rectangular portions.

[0013] By adopting the above technical solution, the structural strength of the connecting rod is improved by reinforcing ribs, and its deformation under stress is suppressed, thereby improving the transmission accuracy and signal accuracy of the vehicle height sensor.

The swing arm 2 is threadedly connected with a screw 7 that is compatible with the threaded sleeve 5. One end of the connecting rod 4 is rotatably connected to the swing arm 2 through the threaded sleeve 5, and the other end is hinged to the ball head screw 8 through the universal sleeve 6.

[0018] Combination Figure 3-5As shown, in this embodiment, the upper mounting head 42 or the lower mounting head 43 is provided with a cylindrical portion 44 and an adapter portion 45.

The ball head screw 8 is used to install the suspension connecting rod of the car. The outer hexagonal part 81 is used to place the hexagonal wrench and is threaded to the nut through the stud part 83. The ball part 82 is used to compensate for the installation error between the car body and the suspension connecting rod and eliminate the problem of the connecting rod 4 bending due to installation stress.

[0019] Combination Figure 6 As shown, in this embodiment, the cylindrical part 44 is provided with a mounting hole 46, and the outer surfaces of the threaded sleeve 5 and the universal sleeve 6 are provided with annular teeth 62 for embedding into the mounting hole 46. The annular teeth 62 increase the contact area between the threaded sleeve 5 or the universal sleeve 6 and the cylindrical part 44, and form an anti-pull-out interlocking structure to avoid the phenomenon of the insert loosening or falling out. The connecting rod 4 is made of a mixture of nylon and glass fiber. The universal sleeve 6 is provided with a cutout 63.
