Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a vehicle body height sensor capable of dynamically self-processing signals. Background Art

[0002] The vehicle height sensor is a sensor that detects the relative displacement of the vehicle body and the lower cantilever. The transmission structure of the vehicle height sensor usually includes a sensor body, a swing arm, a connecting rod and an outer bracket, wherein the sensor body and the outer bracket are respectively connected to the vehicle body and the lower cantilever, the outer bracket is rotatably connected to the swing arm through a connecting rod, one end of the swing arm is fixedly connected to the rotating shaft on the sensor body, and the relative displacement of the vehicle body is fed back through the rotation angle of the rotating shaft.

[0003] However, in traditional vehicle height sensors, the rotating shaft, swing arm, connecting rod and external bracket are usually fixed by bolt connection. If the number of swings increases, the transmission structure will become loose, making it impossible to detect changes in vehicle height in real time, and the suspension control system will not be able to control and adjust the vehicle height according to the vehicle status. Utility Model Content

[0004] In order to overcome the shortcomings of the background technology, the technical solution adopted by the utility model is: a vehicle height sensor with dynamic self-processing signals, including a sensor body, a rotating shaft, a bracket plate, a swing arm, a retaining spring, a connecting rod and an external bracket, the sensor body is connected to the bracket plate, and the sensor body is rotatably connected to the rotating shaft for transmitting signals, the rotating shaft is clamped with the swing arm, one end of the swing arm is hinged with the external bracket through a connecting rod, the other end of the swing arm is installed with a retaining spring, a protrusion is provided on the top of the rotating shaft, the rotating shaft passes through the swing arm and the retaining spring in sequence, and the retaining spring is clamped on the swing arm between the protrusions.

[0005] By adopting the above technical solution, the bracket plate is used to be fixed on the vehicle body, and the outer bracket is fixed on the lower cantilever of the vehicle. When the height of the vehicle body changes, the positional relationship between the bracket plate and the outer bracket changes accordingly. The outer bracket drives the rotating shaft to rotate through the connecting rod and the swing arm, and the change in the height of the vehicle body is detected by the rotation angle of the rotating shaft, which meets the needs of the sensor body to dynamically process the rotation angle signal of the rotating shaft. The rotating shaft is fixed to the swing arm by a retaining spring. Compared with the traditional nut locking structure, the retaining spring will not loosen due to the movement of the swing arm, thereby maintaining the stability of the sensor transmission structure and improving the service life of the product.

[0006] The utility model is further configured that the rotating shaft is provided with an external hexagonal portion, the swing arm is provided with an internal hexagonal groove matching the external hexagonal portion, and the rotating shaft is clamped with the swing arm via the external hexagonal portion.

[0007] By adopting the above technical solution, the rotation directions of the rotating shaft and the swing arm are fixed through the structure of the outer hexagonal portion, thereby avoiding rotational offset between the rotating shaft and the swing arm and reducing the detection error of the sensor.

[0008] The utility model is further configured that the swing arm is provided with a receiving groove above the inner hexagonal groove, the receiving groove is provided with a clamping spring, the inner ring of the clamping spring is provided with elastic parts distributed in a circumference, and the protrusion abuts against the elastic part.

[0009] By adopting the above technical solution, during installation, the swing arm and the retaining spring are installed on the rotating shaft in sequence. When the retaining spring is inserted into the rotating shaft, the elastic part is deformed from the axis to the outside by the action of the protrusion until the retaining spring moves to the preset position. The elastic part is reset and abuts against the bottom surface of the protrusion. It is easy to install and has a stable structure.

[0010] The utility model is further configured to further include a protective cover, which is clamped on the accommodating groove and covers the rotating shaft and the clamping spring member at the same time.

[0011] By adopting the above technical solution, the protective cover is used to cover and protect the rotating shaft and the retaining spring, so as to prevent foreign objects from touching and affecting the connection structure of the retaining spring.

[0012] The utility model is further configured that one side of the bracket plate is provided with a limiting portion for limiting the rotation amount of the swing arm.

[0013] With the above technical solution, the bracket plate adopts an integrated bending process and forms a limiter, which limits the rotation of the swing arm to prevent the swing arm from rotating too much and folding in the reverse direction;

[0014] The utility model is further configured that the connecting rod is provided with a ball socket portion, the swing arm is integrally formed with a ball head portion matching the ball socket portion, and the swing arm is hinged with the connecting rod via the ball head portion.

[0015] Furthermore, the outer bracket is hinged with a ball head rod matching the ball socket, and the outer bracket is hinged with the connecting rod via the ball head rod.

[0016] By adopting the above technical solution, both ends of the connecting rod are respectively connected to the swing arm and the outer bracket by ball joints to compensate for the installation errors of the bracket plate, the outer bracket and the frame, and the application range is wide.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The rotating shaft is fixed to the swing arm by a retaining spring. Compared with the traditional nut locking structure, the retaining spring will not become loose due to the movement of the swing arm, thereby maintaining the stability of the sensor transmission structure and increasing the service life of the product.

The rotating shaft 2 passes through the swing arm 4 and the retaining spring 5 in sequence, and the retaining spring 5 is clamped on the swing arm 4 between the protrusion 21.

[0026] Combination Figure 3 , 4 As shown, in this embodiment, the rotating shaft 2 is provided with an external hexagonal portion 22, and the swing arm 4 is provided with an internal hexagonal groove 41 matching the external hexagonal portion 22. The rotating shaft 2 is clamped with the swing arm 4 through the external hexagonal portion 22. The rotation directions of the rotating shaft 2 and the swing arm 4 are fixed by the structure of the external hexagonal portion 22, thereby avoiding rotational offset between the rotating shaft 2 and the swing arm 4 and reducing the detection error of the sensor.

[0027] In this embodiment, the swing arm 4 is provided with a receiving groove 42 above the hexagonal groove 41, and the receiving groove 42 is provided with a retaining spring 5. The inner ring of the retaining spring 5 is provided with an elastic portion 51 distributed in a circumference, and the protrusion 21 abuts against the elastic portion 51. During installation, the swing arm 4 and the retaining spring 5 are installed on the rotating shaft 2 in sequence.

It is easy to install and has a stable structure.

[0028] In this embodiment, a protective cover 8 is also included. The protective cover 8 is clamped in the accommodating groove 42 and covers the rotating shaft 2 and the retaining spring 5 at the same time. The protective cover 8 is used to cover and protect the rotating shaft 2 and the retaining spring 5 to prevent foreign objects from touching and affecting the connection structure of the retaining spring 5.

[0029] In this embodiment, a limiting portion 31 for limiting the rotation amount of the swing arm 4 is provided on one side of the bracket plate 3. The bracket plate 3 adopts an integrated bending process to form the limiting portion 31. The limiting portion 31 limits the rotation amount of the swing arm 4 to prevent the swing arm 4 from rotating too much and flipping in the reverse direction.
