DETAILED DESCRIPTION

[0037] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0038] In the present disclosure, unless otherwise stated, directional words such as "height direction" refer to the height direction of the vehicle in a normal driving state. Figure 1 , Figure 3 , Figure 4 as well as Figure 6 In the height direction shown, "inside" and "outside" refer to the inside and outside of the contour of the relevant parts. In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another, and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0039] In the related art, the height of the suspension can be obtained by measuring the distance between the vehicle frame (or load-bearing body) and the axle (or wheel). The conventional measurement method is that the operator uses a measuring tool (such as a tape measure or a ruler) to measure the distance between the center hole of the wheel and the lowest point of the vehicle body corresponding to the center hole in the height direction to obtain the height of the suspension. This measurement method is prone to measurement errors and degree errors due to improper operation of the operator, and has low measurement accuracy and low measurement efficiency.

[0040] In view of this, if Figures 1 to 6 As shown, the present disclosure provides a vehicle suspension height measurement system 100, which includes a measuring mechanism 1 and a first fixing mechanism 2. The measuring mechanism 1 includes a slide rail 11, a distance measuring device 12 and a driving device 13. The first fixing mechanism 2 is used to be detachably connected to a wheel 5 of a vehicle. The first end of the slide rail 11 is connected to the first fixing mechanism 2, and the second end of the slide rail 11 extends along the height direction of the vehicle suspension. The distance measuring device 12 is slidably connected to the slide rail 11, and the driving device 13 is used to drive the distance measuring device 12 to slide along the slide rail 11 to measure the height of the suspension.

[0041] like Figure 3 and Figure 6 As shown, when the vehicle suspension height measurement system 100 is used to measure the suspension height of the vehicle, the operator can fix the measuring mechanism 1 on the wheel 5 of the vehicle through the first fixing mechanism 2, so that the measuring mechanism 1 and the vehicle have a stable relative position. The slide rail 11 of the measuring mechanism 1 extends along the height direction of the suspension of the vehicle, and the driving device 13 can drive the distance measuring device 12 to slide along the slide rail 11, and the distance measuring device 12 can move along the height of the suspension to achieve the measurement of the height of the suspension.

[0042] In the above-mentioned measurement process, the first fixing mechanism 2 fixes the measuring mechanism 1 on the wheel 5 of the vehicle. Compared with the operator using a tape measure or a ruler for measurement, the measuring mechanism 1 in the embodiment of the present disclosure can maintain a stable relative position with the vehicle through the first fixing mechanism 2, thereby avoiding measurement errors or reading errors caused by changes in relative position, which is conducive to improving the accuracy of measurement. The driving device 13 can drive the distance measuring device 12 to slide along the slide rail 11 to realize automatic measurement of the height of the suspension. The operator does not need to manually operate the distance measuring device 12, which can simplify the measurement process and improve the measurement efficiency.

[0043] As an exemplary application scenario, the vehicle suspension height measurement system 100 provided by the present disclosure can be used to measure the suspension height of the air suspension of the vehicle. The air suspension has the characteristic of being able to adjust its own suspension height. It is necessary to measure the actual suspension height when the air suspension is adjusted to different suspension height states. The solutions in the related art usually require operators to use measuring tools (such as tape measures or rulers, etc.) to perform multiple manual measurements and readings. The working process is cumbersome, inefficient and has large errors. The vehicle suspension height measurement system 100 provided by the present disclosure can be fixed to the wheel 5 through the first fixing mechanism 2. When the height of the air suspension changes, the driving device 13 can drive the distance measuring device 12 multiple times to realize automatic measurement of the suspension height, which has good measurement efficiency and measurement accuracy.

[0044] Through the above technical solution, the vehicle suspension height measurement system 100 can be fixed on the wheel 5 of the vehicle, and the driving device 13 drives the distance measuring device 12 to automatically measure the height of the suspension. The measuring mechanism 1 and the wheel 5 maintain a stable relative position during the measurement process, which is conducive to reducing the measurement error or reading error and improving the accuracy of the measurement. In addition, there is no need to manually operate the distance measuring device 12 during the measurement process, which simplifies the measurement process and has good measurement efficiency.

[0045] The above-mentioned distance measuring device 12 can be any distance sensor or acquisition device. As an exemplary embodiment, the distance measuring device 12 can optionally include a collector and a processor. The collector is electrically connected to the processor, and the processor obtains the suspension height of the vehicle according to the information collected by the collector. Among them, the above-mentioned collector can be an infrared ranging sensor or a camera, etc. For example, in the embodiment where the collector is an infrared ranging sensor, the infrared ranging sensor moves along the slide rail 11 to detect the position information of the lower end of the vehicle body 6 and / or the position information of the center hole of the wheel 5 of the vehicle during the movement, and transmits the position information to the processor, and the processor can calculate the suspension height of the vehicle. Alternatively, in the embodiment where the collector is a camera, the camera moves along the slide rail 11 and captures the image information of the vehicle body 6 and the wheel 5, and transmits the image information to the processor, and the processor can analyze and calculate the suspension height of the vehicle.

[0046] The distance measuring device 12 is slidably connected to the slide rail 11. The slide rail 11 can be formed into any structure with a slide groove or a slider. The distance measuring device 12 can be formed with a slider portion or a slide groove portion that cooperates with the slide rail 11, so that the distance measuring device 12 can be slidably connected to the slide rail 11. Alternatively, the slide rail 11 can include a guide rod, and the distance measuring device 12 can include a sliding hole. The distance measuring device 12 is sleeved on the guide rod through the sliding hole, so that the distance measuring device 12 can be slidably connected to the slide rail 11. For the specific connection method between the distance measuring device 12 and the slide rail 11, those skilled in the art can realize it according to relevant technologies, and the present disclosure does not make specific restrictions on this.

[0047] The driving device 13 can drive the distance measuring device 12 to move along the slide rail 11 through a variety of structures, such as a screw nut pair, a telescopic rod, a transmission belt or an elastic member. As an exemplary embodiment, optionally, the driving device 13 can be a spring, one end of the spring is connected to the slide rail 11, and the other end of the spring is connected to the distance measuring device 12. The spring is used to drive the distance measuring device 12 to slide along the slide rail 11. When the vehicle suspension height measurement system 100 in this embodiment is used to measure, the first fixing mechanism 2 is installed on the wheel 5, and the operator can pull the distance measuring device 12 to make the distance measuring device 12 located at the lowest point of the slide rail 11. After the operator removes the pulling force, the elastic force of the spring can drive the distance measuring device 12 to slide upward along the slide rail 11. In this process, the distance measuring device 12 can measure the suspension height.

[0048] As another exemplary embodiment, optionally, the driving device 13 can be a linear motor, and the distance measuring device 12 is connected to the mover of the linear motor. In this embodiment, the linear motor can include a linear guide rail, which can be fixedly arranged in parallel with the slide rail 11, and the mover moves along the linear guide rail, while driving the distance measuring device 12 to move along the slide rail 11. Alternatively, the slide rail 11 can be used as a guide rail for the linear motor, that is, the mover of the linear motor is installed on the slide rail 11 so as to be able to move along the slide rail 11, and the distance measuring device 12 is fixedly connected to the mover of the linear motor. The mover in this embodiment is integrated with the slide rail 11, which can simplify the structure of the vehicle suspension height measurement system 100 and improve integration.

[0049] Optionally, a level gauge may be provided on the slide rail 11, and the level gauge may be a bubble level gauge or an electronic level gauge, etc., and the present disclosure does not limit this. When the operator installs the vehicle suspension height measurement system 100 on the vehicle, the slide rail 11 may be detected by the level gauge, and the extension direction of the slide rail 11 may be adjusted to ensure that the slide rail 11 can extend along the height direction of the suspension, thereby improving the measurement accuracy.

[0050] The first fixing mechanism 2 is connected to the first end of the slide rail 11, and the slide rail 11 extends in the height direction. The first fixing mechanism 2 can be connected to the slide rail 11 in a variety of ways. As an exemplary embodiment, Figure 2 As shown, optionally, the first fixing mechanism 2 may include a clamping portion, the clamping portion includes two clamping plates arranged relatively spaced apart, screw holes are formed on the two clamping plates, the first end of the slide rail 11 is also formed with a screw hole, the first end of the slide rail 11 is located between the two clamping plates, and the first end of the slide rail 11 can be connected to the first end of the slide rail 11 by connecting bolts that pass through the screw holes on the clamping plates and the first end of the slide rail 11 at the same time.

[0051] When the vehicle suspension height measurement system 100 measures the suspension height of a vehicle, the vehicle is usually in a static state, that is, the wheels 5 and the vehicle body 6 remain relatively still. However, with the development and update of the suspension, in order to detect the performance of the suspension when the vehicle is in operation, it is necessary to measure the height of the suspension when the vehicle is in operation. Based on this, Figures 4 to 6 As shown, optionally, the first fixing mechanism 2 may include a fixing portion 21 and a rotating connection portion 22, wherein the fixing portion 21 is used to be detachably connected to the wheel 5 of the vehicle, and the fixing portion 21 is rotatably connected to the first end of the slide rail 11 through the rotating connection portion 22. When the vehicle is in a running state, the fixing portion 21 rotates following the wheel 5, and the fixing portion 21 is rotatable relative to the slide rail 11, so that the slide rail 11 can be maintained in a state of extending in the height direction of the suspension, and the distance measuring device 12 moves along the slide rail 11 to measure the suspension height when the vehicle is in a dynamic state, thereby realizing that the vehicle suspension height measurement system 100 is used to measure the suspension height of the vehicle when the vehicle is in a dynamic state.

[0052] The first fixing mechanism 2 can be rotatably connected to the first end of the slide rail 11 in a variety of ways. As an exemplary embodiment, the vehicle suspension height measurement system 100 can optionally include a bearing, and one of the rotating connection part 22 and the first end of the slide rail 11 is sleeved on the inner ring of the bearing, and the other of the rotating connection part 22 and the first end of the slide rail 11 is sleeved on the outer ring of the bearing. Since the inner ring and the outer ring of the bearing can rotate relative to each other, the rotating connection part 22 and the first end of the slide rail 11 can rotate relative to each other. In this embodiment, optionally, the rotating connection part 22 can be formed as a sleeve rod to extend into the inner ring of the bearing, and the first end of the slide rail 11 can be formed with a bearing sleeve to accommodate the bearing and fix it to the outer ring of the bearing.

[0053] In order to enable the vehicle suspension height measurement system 100 to perform measurements when the vehicle is stationary, the first fixing mechanism 2 may further include a locking member, which is used to limit the relative rotation between the first fixing mechanism 2 and the first end of the slide rail 11. The locking member may be a friction plate, a locking screw, or a buckle. The present disclosure does not limit the specific structure of the locking member.

[0054] As another exemplary embodiment, optionally, the vehicle suspension height measurement system 100 may further include a wheel speed meter 4, one of the rotating connection part 22 and the first end of the slide rail 11 is fixedly connected to the housing of the wheel speed meter 4, and the other of the rotating connection part 22 and the first end of the slide rail 11 is sleeved on the gear ring inside the wheel speed meter 4. The vehicle suspension height measurement system 100 in this embodiment can measure the rotation speed of the vehicle's wheel 5 while measuring the suspension height of the vehicle, and its function is more comprehensive. The present disclosure does not specifically limit the type and operating principle of the wheel speed meter 4.

[0055] like Figure 4 As shown, optionally, the vehicle suspension height measurement system 100 may further include a second fixing mechanism 3, the second fixing mechanism 3 is connected to the slide rail 11, and the second fixing mechanism 3 is used to be detachably connected to the vehicle body 6. When the vehicle suspension height measurement system 100 is used to measure the suspension height of the vehicle in a dynamic driving state, due to the rotation of the wheel 5, the first fixing mechanism 2 rotates relative to the slide rail 11, and the second fixing mechanism 3 can fix the slide rail 11 to the vehicle body 6, further ensuring the stability of the slide rail 11 and improving the accuracy of the measurement.

[0056] The second fixing mechanism 3 may be connected to the vehicle body 6 by clamping or adsorption, and optionally, the second fixing mechanism 3 includes an adsorption member 31, and the adsorption member 31 is used to be adsorbed on the vehicle body 6. The adsorption member 31 here may be a suction cup or a vacuum suction cup, and the suction cup or vacuum suction cup is used to be adsorbed on the vehicle body 6. Alternatively, the adsorption member 31 may also be a magnetic member, and the magnetic member may be adsorbed on the vehicle body 6 by magnetism.

[0057] Optionally, the second fixing mechanism 3 may further include a sliding connection portion 32, and the second fixing mechanism 3 may be slidably connected to the slide rail 11 via the sliding connection portion 32, so that the second fixing mechanism 3 can be connected to the vehicle body 6 when suitable for different vehicle models, thereby expanding the application scope of the vehicle suspension height measurement system 100.

[0058] Optionally, the first fixing mechanism 2 may include a main body 23 and a fixing part 21, wherein the main body 23 is connected to the first end of the slide rail 11, and the fixing part 21 is used to be connected to the vehicle. The fixing part 21 may be fixed to any position of the wheel 5 by clamping, sleeve connection, abutment or clamping. As an exemplary embodiment, the fixing part 21 is used to be detachably sleeved on the rim hole 51 of the wheel 5, and the rim hole 51 is the center hole 511 or the bolt hole 512 on the rim of the wheel 5. As another exemplary embodiment, the fixing part 21 is used to detachably clamp the rim of the wheel 5.

[0059] like Figure 2 , Figure 4 and Figure 5 As shown, optionally, the fixing portion 21 may include a plurality of claws 211, and the plurality of claws 211 are arranged around the central axis of the fixing portion 21, and the first end of each claw 211 is fixed to the main body 23, and the second end of the claw 211 is set as a movable end and can approach or move away from the central axis of the fixing portion 21, and the second ends of the plurality of claws 211 are used to be commonly sleeved on the rim hole 51 of the wheel 5. It should be noted that the second end of the claw 211 is set as a movable end, which means that the second end of the claw 211 is not fixedly connected to any structure and can move (the movement here can be movement, rotation or elastic deformation, etc.), the second ends of the plurality of claws 211 can extend into the rim hole 51, and the second ends of the plurality of claws 211 are all against the inner wall of the rim hole 51, so that the claw 211 and the rim hole 51 are tightly sleeved.

[0060] In the above embodiment, the plurality of claws 211 may be made of elastic metal material, and when no external force is applied, the outer diameter of the overall structure formed by the plurality of claws 211 is greater than the outer diameter of the rim hole 51. Alternatively, the fixing portion 21 may include a support member, and the support member may be supported between the plurality of claws 211, and provide support force for the plurality of claws 211 when the plurality of claws 211 are sleeved with the rim hole 51, so as to ensure that the plurality of claws 211 and the rim hole 51 are sleeved stably.

[0061] Optionally, the fixing portion 21 may include a tensioning member 212, and the tensioning member 212 is used to apply a clamping force to the plurality of claws 211 so that the second ends of the plurality of claws 211 are close to each other. Figure 4 As shown, the operator can apply a clamping force to the multiple claws 211 through the tensioning member 212 to make the second ends of the multiple claws 211 approach each other, so that the outer diameter of the overall structure formed by the multiple claws 211 is smaller than the inner diameter of the rim hole 51, so that the second ends of the multiple claws 211 can extend into the rim hole 51. The operator loosens the tensioning member 212, and the multiple claws 211 can press against the inner wall of the rim hole 51 under the action of their own elasticity or the action of the support member, thereby realizing the socket connection between the multiple claws 211 and the rim hole 51.

[0062] In the embodiment where the first fixing mechanism 2 includes a clamping portion, Figure 2 As shown, optionally, the tensioning member 212 can be a clamping portion, that is, a plurality of claws 211 can be accommodated between two clamping plates of the clamping portion, and by adjusting the contact positions of the plurality of claws 211 with the clamping plates, or by adjusting the spacing between the two clamping plates, a clamping force can be applied to the plurality of claws 211 through the clamping plates so that the second ends of the plurality of claws 211 are close to each other.

[0063] As another exemplary embodiment, Figure 5 As shown, optionally, the tensioning member 212 includes a threaded sleeve, and the outer peripheral surfaces of the multiple claws 211 are formed with threads. The threaded sleeve is sleeved on the outside of the multiple claws 211 and threadedly cooperates with the multiple claws 211, and the second ends of the multiple claws 211 extend out of the threaded sleeve. When the threaded sleeve rotates along the threads on the multiple claws 211 to approach the second ends of the claws 211, the second ends of the multiple claws 211 are close to each other.

[0064] Optionally, the first fixing mechanism 2 may include a plurality of fixing portions 21, and each fixing portion 21 may be respectively used to be sleeved on the center hole 511 or the bolt hole 512 of the wheel 5. Figure 6 As shown, optionally, a plurality of fixing portions 21 are arranged at intervals along the circumference of the main body 23, so that the plurality of fixing portions 21 can be respectively sleeved on the plurality of bolt holes 512 of the wheel 5. In the above embodiment, optionally, a plurality of long holes 231 corresponding to the plurality of fixing portions 21 can be formed on the main body 23, and the long holes 231 extend along the radial direction of the main body 23, and the fixing portions 21 can be slidably connected to the long holes 231. That is, each fixing portion 21 can move along the long hole 231 to adjust the spacing between the fixing portion 21 and the center hole 511 of the wheel 5, so that the vehicle suspension height measurement system 100 in the above embodiment can be applicable to wheels 5 of different sizes, thereby expanding the application range of the vehicle suspension height measurement system 100.

[0065] In the embodiment where the first fixing mechanism 2 includes a plurality of fixing portions 21, since the plurality of fixing portions 21 are movable relative to their corresponding long holes 231, the operator needs to move and align each fixing portion 21 when installing the first fixing mechanism 2. Figure 5As shown, optionally, the first fixing mechanism 2 also includes a synchronization turntable 24, which is coaxially arranged with the main body 23 and rotatably connected to the main body 23, and the synchronization turntable 24 includes at least two abutment surfaces 241, each of which is arranged at an angle to the radial direction of the synchronization turntable 24, and each of the abutment surfaces 241 can abut against the corresponding fixed portion 21, so that when the synchronization turntable 24 rotates, each abutment surface 241 can push its corresponding fixed portion 21 to move synchronously toward or away from the central axis of the fixed portion 21.

[0066] In the above embodiment, if Figure 5 As shown, optionally, the main body 23 can be formed as a plate-like structure, on which a long hole 231 is formed, and the fixing portion 21 includes a claw 211, a tensioning member 212 and a connecting bolt, the claw 211 and the tensioning member 212 are both located on the first side of the plate-like structure, the connecting bolt passes through the long hole 231, and the bolt head of the connecting bolt is located on the second side of the plate-like structure, the synchronous turntable 24 is located on the second side of the plate-like structure, and the abutment surface 241 of the synchronous turntable 24 is used to abut against the bolt head.
