Description

Technical Field

[0001] This utility model relates to the field of sensors, and in particular to a vehicle height sensor. Background Technology

[0002] Vehicle height sensors are increasingly being widely used in various passenger cars. Existing vehicle height sensors include various types such as Hall effect, photoelectric, and eddy current sensors. Most vehicle height sensors consist of a housing and a rocker arm. The two ends of the rocker arm are connected to the housing and the vehicle suspension, respectively. When the vehicle height changes, the suspension drives the rocker arm to rotate relative to the housing. The rocker arm converts the change in vehicle height into an angle of rotation within the housing. By placing sensing components in the rocker arm and housing, and using different detection methods such as electromagnetic induction or photoelectric induction, the rotation angle is converted into a corresponding data signal, thus enabling the detection of vehicle height.

[0003] In the prior art, patent application number CN202320926696.5 discloses a car body height sensor, including a connecting plate and a car body height sensor. The car body height sensor has grooves machined on the lower left and right sides respectively. The inner walls of the two grooves are respectively connected to a fixing structure. A first arc plate is fixed to the top front of the car body height sensor. The slider in the fixing structure slides back and forth on the inner wall of the groove, thereby driving the vertical cylinder to move back and forth, so that the inner wall of the vertical cylinder is aligned with the top connection port of the roof beam. Then, the bolt is unscrewed through the thread on the inner wall of the vertical cylinder and connected to the thread on the top of the roof beam, thus completing the installation of the car body height sensor.

[0004] The existing vehicle height sensor involves complex disassembly and repair processes, increasing maintenance costs and time. The connection between the connecting rod and the snap-fit ​​component uses complex methods, such as screw fixing, making installation and disassembly cumbersome and inconvenient for routine maintenance and replacement. The excessive number of parts and connection points not only increases manufacturing costs but also reduces the sensor's reliability and durability. Therefore, it is necessary to improve this structure to overcome these shortcomings. Utility Model Content

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with the illustrations and specific embodiments.

[0030] like Figures 1 to 5 As shown, the present invention proposes a vehicle height sensor, comprising,

[0031] The base provides support and installation space. In use, the base is fixedly installed on the frame, forming an integral part with the frame, and provides support for components such as rotating parts and linkage units.

[0032] The rotating part is mounted on the base and can rotate around the circumference of the base. When the vehicle height changes, the linkage unit connected to the rotating part will drive the rotating part to rotate around the base, thereby triggering the Hall component inside the sensor to generate an electrical signal output.

[0033] A linkage unit, wherein a first end of the linkage unit is disposed on a rotating part, and a second end of the linkage unit extends outward from the rotating part; the linkage unit includes...

[0034] Connecting rod one, the first end of the connecting rod one is installed on the rotating part and can move synchronously with the rotating part, and the second end of the connecting rod one is provided with a mounting hole that penetrates through the height direction of the connecting rod one;

[0035] The connector has a connecting part on its first end and a snap-fit ​​connector on its second end. The first end of the connector is mounted on the connecting rod by the connecting part and the mounting hole.

[0036] Connecting rod 2, with a snap-fit ​​part 1 on the first end of the connecting rod 2, one end of the snap-fit ​​part 1 being detachably connected to the connecting rod 2, and a snap-fit ​​hole 1 on the other end of the snap-fit ​​part 1; connecting rod 2, with a snap-fit ​​part 2 on the second end of the connecting rod 2, one end of the snap-fit ​​part 2 being detachably connected to the connecting rod 2, and a snap-fit ​​hole 2 on the other end of the snap-fit ​​part 1; the first end of the connecting rod 2 is installed on the connecting rod by engaging with the snap-fit ​​part 1 through the snap-fit ​​hole 1.

[0037] In use, the first end of connecting rod one is installed on the rotating part and moves synchronously with the rotating part. The second end cooperates with the connector through the mounting hole to transmit the rotation of the rotating part to the connector. The first end of connecting rod two is installed together with the snap-fit ​​connector of the connector through snap-fit ​​hole one. The second end is connected to the vehicle suspension system through snap-fit ​​connector two. When the vehicle height changes, the vehicle suspension system will drive connecting rod two to move, and then transmit this change to the rotating part through the connector and connecting rod one.

[0038] The first end of the connecting rod and the rotating part are integrally formed, and there are no additional connecting parts or joints between the connecting rod and the rotating part, which reduces the error caused by loose connection or wear.

[0039] The inner wall of the mounting hole is provided with an internal thread; the outer surface of the connecting part is provided with an external thread that matches the internal thread; the threaded connection is easier to disassemble and repair. When it is necessary to replace or repair the sensor component, the operator can simply rotate the connecting part to remove it from the mounting hole.

[0040] Both connection hole one and connection hole two are spherical holes, and the snap-fit ​​connector is a spherical part that matches connection hole one. When the snap-fit ​​connector is inserted into connection hole one, its spherical part will automatically position and match the spherical hole. The tight fit between the spherical part and the spherical hole will form a firm connection, which helps to prevent the connector from loosening under vibration or impact. Furthermore, the connection between the spherical hole and the spherical part is still easy to disassemble. The operator only needs to apply enough force to pull the snap-fit ​​connector out of connection hole one. This easy disassembly feature makes the maintenance and replacement of the sensor more convenient.

[0041] The first and second snap-fit ​​components have the same structure, both including a snap-fit ​​body. One end of the snap-fit ​​body is provided with a snap-fit ​​groove, which matches the end of the second connecting rod. The snap-fit ​​body can be detachably mounted on the second connecting rod through the snap-fit ​​groove.

[0042] During installation, the operator first aligns the snap-fit ​​groove of the main body of the snap-fit ​​component with the end of the second connecting rod. Then, the snap-fit ​​component is pushed into place until the snap-fit ​​groove and the end of the second connecting rod are tightly engaged. The snap-fit ​​component is then securely fixed to the second connecting rod. When it is necessary to remove the snap-fit ​​component, the operator simply applies a force in the opposite direction to the installation process to easily remove the snap-fit ​​component from the second connecting rod.

[0043] The connector has a first end that is mounted on the base and integrally connected to the base, and a terminal on the second end of the connector. The connector is connected to an external power source via an adapter and is used to power the sensor.

[0044] The working principle of this utility model is as follows: The base is fixedly installed on the vehicle frame. Then, the rotating part is installed on the base, and the connecting rod unit is connected. When connecting the connecting rod unit, ensure that the first end of connecting rod one is installed on the rotating part, and the second end mates with the connector through the mounting hole. Next, the first end of connecting rod two is installed together with the snap-fit ​​connector of the connector through snap-fit ​​hole one, and the second end is connected to the vehicle suspension system through snap-fit ​​connector two. Connect the adapter of the connector plug to an external power source to power the sensor. When the vehicle height changes, the vehicle suspension system will move connecting rod two. This movement is transmitted to the rotating part through the connector and connecting rod one, thereby triggering the Hall effect sensor inside the sensor to generate an electrical signal output.

[0045] In summary, this vehicle height sensor offers advantages such as structural stability, ease of maintenance, strong adaptability, and convenient power supply. It can maintain vehicle stability and comfort by monitoring changes in vehicle height in real time and adjusting suspension damping and stiffness, thereby improving driving safety and passenger experience.
