[0097] Optionally, the swing arm 2 and the first connecting rod 35 can be rotatably connected by means of threaded connection or shaft hole matching, which can be specifically configured according to actual needs and is not specifically limited in the embodiment of the present invention.

[0098] Optionally, a fifth rotating member 21 may be provided at the end of the swing arm 2, and a sixth rotating member 352 matching the fifth rotating member 21 may be provided on the first connecting rod 35. One of the fifth rotating member 21 and the sixth rotating member 352 is a ball pin, and the other is a spherical seat, so as to facilitate the rotational connection between the fifth rotating member 21 and the sixth rotating member 352, and further realize the rotational connection between the swing arm 2 and the first connecting rod 35.

[0099] Specifically, the fifth rotating member 21 may be a ball pin, and the corresponding sixth rotating member 352 may be a spherical seat; or, the fifth rotating member 21 may be a spherical seat, and the corresponding sixth rotating member 352 may be a ball pin.

[0100] Specifically, the first rotating member 351 and the sixth rotating member 352 can be respectively provided at both ends of the first connecting rod 35. The first rotating member 351, the first connecting rod 35, and the sixth rotating member 352 can be fixed by splicing, or the first rotating member 351, the first connecting rod 35, and the sixth rotating member 352 can be integrally formed. The specific settings can be made according to actual needs, and the embodiment of the present invention does not make any specific limitations on this.

[0101] For example, Fig. 7A and Figure 7B As shown, the first rotating member 351 and the sixth rotating member 352 are both spherical seats, and the first rotating member 351, the first connecting rod 35 and the sixth rotating member 352 are integrally formed to form a double ball pin seat. The axial direction of the first rotating member 351 is along the first direction, and the axial direction of the sixth rotating member 352 is along the third direction, the third direction intersects with the first direction, and the angle between the third direction and the first direction can be an acute angle, a right angle or an obtuse angle. The third direction and the second direction are skewed or parallel, which can be set according to actual needs, and the embodiment of the present invention does not specifically limit this.

[0102] Specifically, the swing arm 2 can be fixedly connected to the fifth rotating member 21 via a connecting rod, or the main body of the swing arm 2 can be directly fixedly connected to the fifth rotating member 21, or the swing arm 2 can be integrally formed with the fifth rotating member 21.

[0103] Specifically, by loosening the second locking member 331, the first rotating member 351 and the second rotating member 312 can rotate relative to each other, and the phase angle at both ends of the connecting rod 3 can be adjusted; by locking the second locking member 331, the phase angle between the two ends of the connecting rod, i.e., the connecting end and the movable end, can be locked, and jamming between the swing arm 2 and the suspension can be avoided.

[0104] Specifically, since the length of the connecting rod 3 in the first direction can be adjusted, the phase angle between the connecting end and the movable end of the connecting rod 3 can also be adjusted, which can greatly improve the flexibility of the height sensor arrangement to enhance the adaptability of the height sensor. In the development process of some height sensors, the height sensor in the embodiment of the present invention can solve the problems such as the misalignment of the length design of the connecting rod 3 due to lack of experience, which leads to the inability of the connecting rod 3 to return to its original position during the movement of the suspension, and the jamming of the ball pins at both ends of the height sensor due to the low overall assembly accuracy of the suspension. Moreover, the height sensor in the embodiment of the present invention can also avoid problems such as mold scrapping due to design errors, greatly shortening the development cycle of parts and vehicles.

[0105] For example, Figure 5 and Figure 6As shown, the first rotating member 351, the seventh rotating member 322, and the sixth rotating member 352 are spherical seats, and the second rotating member 312, the eighth rotating member 34, and the fifth rotating member 21 are ball pins. The following description is based on this situation:

[0106] The assembly sequence of the connecting rod 3 of the height sensor includes:

[0107] Step 1: Spin the eighth rotating member 34 into the seventh rotating member 322;

[0108] Step 2: Spin the second rotating member 312 into the first rotating member 351;

[0109] Step 3: Sleeve the first gasket 333 outside the third connecting rod 31;

[0110] Step 4: Sleeve the first locking member 332 outside the third connecting rod 31;

[0111] Step 5: Install the second locking member 331 outside the third connecting rod 31;

[0112] Step 6: Thread the third connecting rod 31 and the second connecting rod 32;

[0113] Step 7: According to the length requirement of the connecting rod 3, use the first locking piece 332 to lock the first connecting rod 35 and the third connecting rod 31; according to the angle requirement of the connecting rod 3, use the second locking piece 331 to lock the second connecting rod 32 and the third connecting rod 31 to complete the assembly of the connecting rod 3.

[0114] In the assembled state of the vehicle, the length adjustment principle of the connecting rod 3 is as follows:

[0115] Loosen the first locking piece 332 and the second locking piece 331, so that the third connecting rod 31 is unlocked relative to the first connecting rod 35 and the second connecting rod 32 respectively; use a wrench to clamp the first clamping portion 3111 on the third connecting rod 31, and use another adjustment wrench to clamp the second clamping portion 3211 on the second connecting rod 32, so that the first threaded rod can rotate and retract in the first threaded sleeve. A certain gap space is reserved in the first threaded sleeve so that the first threaded rod can rotate clockwise or counterclockwise in the first threaded sleeve, thereby realizing that the length of the connecting rod 3 in the first direction can be extended or shortened.

[0116] When the length of the connecting rod 3 in the first direction is adjusted to a desired length, the first locking member 332 and the second locking member 331 are locked. At this time, the first connecting rod 35, the second connecting rod 32 and the third connecting rod 31 can form a rigid member with a certain length.

[0117] In the assembled state of the vehicle, the angle adjustment principle of the connecting rod 3 is as follows:

[0118] Release the first locking piece 332. At this time, the second locking piece 331 can be in a locked state, so that the third link 31 and the second link 32 are used as a whole rigid part. By rotating the rigid part, the first link 35 and the third link 31 can rotate relative to each other. When the link 3 rotates to the desired angle, the first locking piece 332 is locked, thereby realizing the adjustment of the phase angle at both ends of the link 3, that is, the phase angle adjustment between the first link 35 and the second link 32.

[0119] The height sensor described in the embodiment of the present invention has at least the following advantages:

[0120] In an embodiment of the present invention, the length of the connecting rod can be adjusted, and the connecting end of the connecting rod is connected to the sensor body, and the movable end of the connecting rod is connected to the suspension. In this way, when the height sensor is assembled on the whole vehicle, if a design error is found or the error of the whole vehicle is large, the length of the connecting rod can be adjusted to meet the assembly requirements, which can avoid design errors in the development process of the height sensor and the problem of scrapping of the connecting rod mold due to design errors, and can shorten the development cycle of parts and vehicles. Moreover, since the length of the connecting rod of the height sensor in the embodiment of the present invention can be adjusted, the height sensor can adapt to different vehicle models.

[0121] In the second aspect, an embodiment of the present invention further discloses a vehicle, which may specifically include a vehicle body, a suspension and the above-mentioned height sensor, wherein the sensor body 1 may be connected to the vehicle body, and the movable end of the connecting rod may be connected to the suspension.

[0122] Specifically, when the suspension moves, it drives the movable end of the connecting rod 3 of the height sensor to move. The connecting end of the connecting rod 3 transmits the movement to the sensor body 1. The chip in the sensor body 1 converts the detection signal and outputs it to the suspension electronic controller. The electronic controller outputs the corresponding control strategy to ensure the posture, comfort, and handling of the suspension.

In this way, when the height sensor is assembled on the whole vehicle, if a design error is found or the error of the whole vehicle is large, the length of the connecting rod can be adjusted to meet the assembly requirements, which can avoid design errors in the development process of the height sensor and the problem of scrapping of the connecting rod mold due to design errors, and can shorten the development cycle of parts and vehicles. Moreover, since the length of the connecting rod of the height sensor in the embodiment of the present invention can be adjusted, the height sensor can adapt to different vehicle models.
