Description

Technical Field

[0001] This utility model relates to a sensor, specifically a vehicle suspension height sensor. Background Technology

[0002] Vehicle suspension height sensors are used in air suspension and active suspension systems in automobiles to detect vehicle height (the relative displacement between the vehicle body and the lower suspension arm or shock absorber support in the vertical direction).

[0003] Currently, common vehicle suspension height sensors typically employ photoelectric sensors. The sensor body is mounted on the vehicle body, and a control linkage converts the vertical movement of the suspension into the rotational movement of a disk slot. Changes in the output of the photoelectric sensor detect the vehicle height and convert this into an electrical signal input to the control device.

[0004] With current technology, a sealed chamber must be designed to prevent light leakage, which makes manufacturing requirements more demanding and increases the overall manufacturing cost. Utility Model Content

[0036] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] Example:

[0038] See Figure 1 and Figure 2 This embodiment discloses a vehicle suspension height sensor, including a cantilever connector 10, a body connector 20, a support rod 30, a drive rod 40, a winding 50, and a slider 60, wherein the cantilever connector 10 is disposed on the lower cantilever of the vehicle suspension, and the body connector 20 is disposed on the vehicle body.

[0039] Specifically, the cantilever connector 10 is arranged horizontally, and its length direction is consistent with the length direction of the lower cantilever of the vehicle suspension. The body connector 20 is also arranged horizontally and is located above the cantilever connector 10, while the body connector 20 and the cantilever connector 10 are parallel to each other.

[0040] One end of the support rod 30 is mounted on the body connector 20 and is set perpendicular to the body connector 20. The support rod 30 is set in a vertically downward direction and is also close to one end of the body connector 20.

[0041] One end of the drive rod 40 is slidably mounted on the cantilever connector 10 and can reciprocate along the length of the cantilever connector 10. The drive rod 40 is also rotatably mounted on the support rod 30 and is arranged in an inclined direction. When the cantilever connector 10 moves up and down, the drive rod 40 can rotate and reciprocate along the length of the cantilever connector 10.

[0042] The winding 50 is disposed on the body connector 20, and the length direction of the winding 50 is consistent with the length direction of the body connector 20. The aforementioned sliding plate 60 is in sliding contact with the winding 50, and the sliding plate 60 is poweredly connected to the end of the drive rod 40 away from the cantilever connector 10, and reciprocates along the length direction of the winding 50 under the drive of the cantilever connector 10.

[0043] A wire 70 is provided at each end of the winding 50, and the wires 70 at both ends of the winding 50 are connected to the same electrode, and a switch is provided on each of the two wires 70. A wire 70 is also connected to the slider 60, and the wire 70 on the slider 60 is connected to another electrode, such as the wires 70 at both ends of the winding 50 being connected to the same cathode, and the wire 70 on the slider 60 being connected to the anode.

[0044] Under normal circumstances, both switches are in the off position when the vehicle suspension height is not adjusted. When the suspension height needs to be adjusted, simply turn on the corresponding switch.

[0045] During the adjustment of the suspension height, one end of the drive rod 40 slides on the cantilever connector 10 and rotates on the support rod 30, causing the slide plate 60 set on the drive rod 40 to slide on the winding resistance 50, thereby realizing the change of resistance value and thus realizing the purpose of calculating the suspension lifting height.

[0046] The overall structure of this technical solution is simple, and it has the advantages of low manufacturing difficulty and low manufacturing cost.

[0047] In this embodiment, the change in resistance value can be converted into the change in the height value of the suspension rising or falling by using instruments such as a modified multimeter or ohmmeter.

[0048] Generally, under normal conditions, the suspension height is at a moderate level, at which point the slider 60 is located in the middle of the winding 50, and the end of the drive rod 40 is located in the middle of the cantilever connector 10.

[0049] In one specific embodiment:

[0050] The vehicle suspension height sensor also includes a telescopic rod 80. Specifically, the end of the drive rod 40 away from the cantilever connector 10 is rotatably mounted on the support rod 30. A gear 100 is provided on the end of the drive rod 40 that is rotatably connected to the support rod 30. One end of the telescopic rod 80 is also rotatably connected to the support rod 30, and a gear 100 is also provided at the end of the telescopic rod 80. The gear 100 on the support rod 30 meshes with the gear 100 on the telescopic rod 80.

[0051] The other end of the telescopic rod 80 is slidably connected to the vehicle body connector 20, and the aforementioned sliding piece 60 is provided on this end of the telescopic rod 80.

[0052] In this embodiment, the end of the drive rod 40 is rotatably connected to the support rod 30, so that when the suspension connector moves up and down, the drive rod 40 rotates around the rotation connection point between it and the support rod 30, and under the action of the two gears 100, the rotation of the drive rod 40 is transmitted to the telescopic rod 80, so that the other end of the telescopic rod 80 slides on the body connector 20, and the length of the telescopic rod 80 also changes accordingly.

[0053] Understandably, by directly designing the slider 60 at the end of the drive rod 40 and rotatably connecting the middle of the drive rod 40 to the support rod 30, although the drive rod 40 can drive the slider 60 to move on the winding 50, the movement trajectory of the slider 60 is arc-shaped, and due to the limited distance between the two ends of the drive rod 40 and the rotatable connection point, the movement distance of the slider 60 is also limited, resulting in a small change in the resistance value on the winding 50, and consequently, low measurement accuracy. However, by setting the telescopic rod 80, the displacement of the slider 60 can be amplified, and the slider 60 can be made to move only along the length direction of the winding 50, thereby improving the measurement accuracy.

[0054] Preferably, in order to further amplify the displacement of the slider 60, the pitch circle diameter of the gear 100 at the end of the drive rod 40 is made larger than the pitch circle diameter of the gear 100 at the end of the telescopic rod 80. The ratio of the pitch circle diameters of the two gears 100 can be selected as 2:1.

[0055] In another specific embodiment:

[0056] The cantilever connector 10 is also provided with a guide rail 90, and the end of the telescopic rod 80 away from the drive rod 40 is slidably mounted on the guide rail 90. The telescopic rod 80 includes a connecting rod 81 and a movable rod 82. One end of the connecting rod 81 is rotatably mounted on the support rod 30, and this end of the connecting rod 81 is connected to the end of the drive rod 40 via the two gears 100 mentioned above. The other end of the connecting rod 81 has a groove 83 along its length. One end of the movable rod 82 is slidably mounted in the groove 83, and the other end of the movable rod 82 is slidably mounted on the guide rail 90 via a slider. The aforementioned sliding plate 60 is mounted on the slider.

[0057] This embodiment discloses a specific structure of a telescopic component, but it does not mean that the structure of the telescopic component is limited to this.

[0058] Preferably, the movable rod 82 is provided with two connecting posts 84, both of which are slidably disposed within the sliding groove 83, with a gap between the two connecting posts 84. This design ensures that the relative movement between the movable rod 82 and the connecting rod 81 is limited to their length directions.

[0059] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
