Description
Technical Field
[0001] The utility model relates to the technical field of sensors, in particular to a height sensor. Background Art
[0002] In the automotive field, height sensors are a vital component that is widely used in automotive suspension systems. Their main function is to monitor the vehicle's suspension status in real time, and then adjust the vehicle height to ensure driving stability and comfort. With the rapid development of the automotive industry, the requirements for vehicle dynamic performance are increasing, and accurate and reliable vehicle height detection has become particularly important. This type of sensor is usually installed at the suspension beam position of a car or motorcycle, and is directly involved in the feedback control of the vehicle's shock absorption system, playing a key role in maintaining the correct body posture and ground clearance.
[0003] However, existing height sensor designs face several challenges in practical applications. In particular, during installation and use, the sensor's sensitive component, the swing arm, is susceptible to accidental touch or external force interference, causing its initial position to shift. This shift not only directly affects the accuracy of the sensor's measurement, but may also trigger a series of chain reactions, such as improper adjustment of the suspension system, reduced vehicle driving stability, and reduced ride comfort. Such problems are particularly prominent during frequent vehicle maintenance operations or complex road conditions, which brings inconvenience to vehicle performance maintenance and may increase users' maintenance costs.
[0004] In view of the above technical limitations, the present application proposes a swing arm height sensor that can correct deviations by itself. Utility Model Content
[0005] In view of the deficiencies in the background technology, the utility model provides a height sensor.
[0006] The technical solution adopted by the utility model is: a height sensor, including an outer shell, a swing arm connected to the outer shell through a rotating shaft, a circle of annular steps is provided on the shaft cylinder below the swing arm, a swing limit groove is provided on the annular step below the swing arm, an arc guide rod is provided in the swing limit groove, a slider is slidably connected to the arc guide rod, the slider is connected to the swing arm through a connecting rod, and correction springs are provided on both ends of the slider and on both side walls of the swing limit groove, and the correction spring can correct the swing arm after the swing arm deviates.
[0007] Furthermore, a fixing hole is provided at the end of the swing arm, and a metal ring is provided in the fixing hole.
[0008] Furthermore, the swing arm is provided with a plurality of penetrating hollow holes, and a through hole is provided on the swing arm in the middle of the hollow holes.
[0009] Furthermore, a plurality of reinforcing ribs are provided between the shaft cylinder and the side wall of the outer shell.
[0010] Furthermore, threaded holes are provided on the side walls on both sides of the outer shell.
[0011] Furthermore, the outer circle of the threaded hole is provided with a circle of annular groove, and a rubber ring is installed in the annular groove.
[0012] The beneficial effects of the utility model are:
[0013] Improved measurement accuracy: The automatic correction mechanism consisting of a correction spring, a slider and an arc-shaped guide rod can automatically correct the abnormal deviation of the swing arm, ensuring that the sensor can still return to the accurate working position even in the event of accidental touch or installation error, thereby significantly improving the accuracy and reliability of vehicle height detection.
[0014] Enhanced anti-interference ability: The annular step and swing limit groove structure in the design effectively limit the unnecessary swing range of the swing arm. Combined with the effect of the correction spring, it greatly enhances the sensor's resistance to external interference and ensures stable operation in complex usage environments.
[0015] Simplified maintenance and installation: Through the above structural optimization, the frequency of sensor failures caused by misoperation is reduced, and the installation and maintenance process is simplified. Once a slight deviation occurs, it can self-adjust, reducing the dependence on professional calibration and saving maintenance costs and time.
[0016] In addition to the objects, features and advantages described above, the present invention has other objects, features and advantages.
[0017] The present invention will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0024] The utility model provides a height sensor.
[0025] In this embodiment, refer to Figure 1-3 The height sensor comprises an outer shell 1, a swing arm 3 connected to the outer shell through a rotating shaft 2, a circle of annular steps 4 are arranged on the shaft cylinder 13 below the swing arm, a swing limit groove 5 is arranged on the annular step below the swing arm, an arc guide rod 6 is arranged in the swing limit groove, a slider 7 is slidably connected to the arc guide rod, the slider and the swing arm are connected by a connecting rod 8, and correction springs (not shown in the figure) are arranged on both ends of the slider and the side walls of the swing limit groove, and the correction spring can correct the swing arm after the swing arm deviates.
[0026] In the above technical solution, by setting an annular step and a swing limit groove on the rotating shaft below the swing arm, and combining the linkage design of the arc guide rod, slider and connecting rod, as well as the instant feedback effect of the correction spring, the height sensor can automatically correct the deviation of the swing arm caused by external force, which significantly improves the working stability of the sensor and the accuracy of measurement, ensures high-precision vehicle height detection under complex working conditions, and improves the overall performance of the vehicle suspension system.
[0027] Specifically, a fixing hole 9 is provided at the end of the swing arm, and a metal ring 10 is provided in the fixing hole.
