Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a hard point measuring tool and a vehicle. Background Art

[0002] With economic development and the increasing improvement of highway networks, the demand for driving safety is also increasing. The leaf springs in the suspension systems of related technologies have a certain impact on the movement of the steering rod. For vehicles with integral leaf spring suspension, interference between the steering and suspension systems is prone to occur during high-speed emergency braking. This means that the steering knuckle arm of the steering system moves with the leaf spring on one hand, while also exhibiting a swinging motion trajectory on the other. This can cause the vehicle to veer off course, affecting braking and wheel bounce performance. In severe cases, the vehicle can even veer into the oncoming lane, compromising driving safety. When the car traverses bumpy roads, the steering wheel can oscillate abnormally, even hitting the driver's hand. This requires the driver to apply a corrective force to the steering wheel, increasing the driver's operational burden and easily causing driver fatigue, which in turn affects driving safety.

[0032] In the description of the present invention, “plurality” means two or more.

[0033] In the description of the present invention, a first feature being “above” or “below” a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact via another feature therebetween.

[0035] The following describes a hard point measurement tool 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0036] like Figure 1-Figure 4 As shown, the hard point measurement tool 1 according to an embodiment of the present invention includes: a plurality of measurement modules 10 and a steering knuckle arm positioning member 200.

[0037] Multiple measurement modules 10 are installed at different locations on the vehicle frame. A knuckle arm locator 200 is adapted to be mounted on the knuckle arm 20. Multiple measurement modules 10 are connected to the knuckle arm locator 200. Together, the multiple measurement modules 10 measure the spatial position of the knuckle arm locator 200 to adjust the installation position of the knuckle arm 20.

[0038] For example, each measurement module 10 is a wire-type displacement sensor, comprising a sensor and a connector connected to the knuckle arm locator 200. Based on the length of the measurement module 10 extending to the knuckle arm locator 200, the measurement module 10 measures the distance between the sensor body 131 and the knuckle arm locator 200. In other words, the measurement module 10 uses the sensor body 131 as the origin for measurement. Because the measurement module 10 is mounted on the vehicle frame, the coordinates of the measurement module 10's origin can be determined based on the location of the frame hole. The other end connects to the knuckle arm locator 200 to measure the length of the knuckle arm 20. Multiple measurement modules 10 can be distributed in front of, behind, and above the knuckle arm 20. The knuckle arm locator 200 is mounted on the knuckle arm 20 to simulate the characteristic position of the knuckle arm 20.

[0039] According to the hard point measurement tool 1 of the embodiment of the present invention, multiple measurement modules 10 are connected to the steering knuckle arm positioning part 200 to facilitate the measurement of the spatial position. Specifically, the theoretical installation position of the steering knuckle arm 20 can be predetermined by utilizing the spatial geometric characteristics during vehicle design. First, the position of the measurement point of the measurement module 10 is calibrated with the frame. Once the frame position is determined, the position coordinates of the measurement module 10 can be obtained. Multiple measurement modules 10 can obtain distance data from the steering knuckle arm positioning part 200 at different measurement positions. For example, the distances between the measurement positions of multiple measurement modules 10 and the steering knuckle arm positioning part 200 are r1, r2, r3..., respectively, and the coordinates of the measurement points of each of the multiple measurement modules 10 are also determined. Multiple measurement modules 10 are connected to the same point. The coordinates of the steering knuckle arm positioning part 200 can be calculated by combining the distance data of multiple measurement modules 10. The coordinates of the steering knuckle arm locator 200 calculated by the multiple measurement modules 10 are compared with the coordinates of the theoretical installation position to determine the deviation distance for installing the steering knuckle arm 20. The steering knuckle arm locator 200 can then be adjusted, for example by replacing the leaf spring and adjusting the position of the steering knuckle arm 20, ultimately ensuring that the steering knuckle arm 20 is installed in the correct position. This avoids an improper kinematic relationship between the leaf spring and the steering rod, and prevents the driver from experiencing abnormal steering wheel swing during braking or bumpy conditions, ensuring safety and reducing the driver's burden.

[0040] Therefore, the hard point measuring tool 1 according to the embodiment of the present invention can better adjust the installation position, and has the advantages of good safety and reduced burden on the driver.

[0041] In some specific embodiments of the present invention, Figure 2 As shown, the plurality of measurement modules 10 include a first measurement module 11 , a second measurement module 12 and a third measurement module 13 .

[0042] The first measuring module 11, the second measuring module 12 and the third measuring module 13 respectively correspond to different frame hole positions of the frame. The first measuring module 11 extends horizontally to the outside of the frame by a first distance, the second measuring module 12 extends horizontally to the outside of the frame by a second distance, and the third measuring module 13 extends horizontally to the outside of the frame by a third distance.

[0043] Since the frame holes are evenly arranged along the length and height directions of the frame, the measurement module 10 is aligned with the position of the frame hole. The coordinates of the first measurement module 11, the second measurement module 12 and the third measurement module 13 can be obtained based on the coordinates of the frame hole. Then, by measuring the distance extended to the steering knuckle arm locating member 200 by collecting the pull line 132, the coordinates of the installation position of the steering knuckle arm locating member 200 can be obtained. The steering knuckle arm locating member 200 indicates the installation position of the steering knuckle arm 20, and the installation position of the steering knuckle arm 20 is adjusted.

[0044] Furthermore, if Figure 2 As shown, the first measuring module 11 , the second measuring module 12 and the third measuring module 13 are arranged in a triangle.

[0045] For example, the first and second measurement modules 11, 12 are located above the third measurement module 13, and the third measurement module 13 is equidistant from the first and second measurement modules 11, 12. In this way, the coordinates of the corresponding positions of the frame holes are determined using the frame holes where the first, second, and third measurement modules 11, 12, and 13 are located as reference points. By extending the coordinates outward by a predetermined distance, the accurate coordinates of the first, second, and third measurement modules 11, 12, and 13 are ultimately obtained. The first, second, and third measurement modules 12, 13 are relatively dispersed, and measuring the distances from each point to the steering knuckle arm locator 200 can reduce measurement errors. During the design phase, the coordinates of the first, second, and third measurement modules 11, 12, and 13 are used to form a sphere with the corresponding measurement distances as the radius. The intersection of the three spheres in space determines the theoretical installation position of the steering knuckle arm 20. The measured position is then compared with the theoretical installation position, and the installation position of the steering knuckle arm 20 is adjusted to ensure accurate installation.

[0046] In some specific embodiments of the present invention, Figure 3 As shown, each measurement module 10 includes a mounting rod 110 , a measurement positioning fixture 120 and a position sensor 130 .

[0047] The mounting rod 110 is mounted in a frame hole of the vehicle frame and extends horizontally outward from the vehicle frame. The measuring and positioning fixture 120 is mounted on the end of the mounting rod 110 that is outside the vehicle frame. The position sensor 130 is mounted on the measuring and positioning fixture 120 and connected to the steering knuckle arm positioning member 200.

[0048] By extending mounting rod 110 horizontally outward a predetermined distance, other axle structures can be avoided and lateral coordinates can be obtained. This brings position sensor 130 closer to knuckle arm locator 200, shortening the distance measured by knuckle arm locator 200. Measurement and positioning tool 120 is installed at one end of mounting rod 110 outside the vehicle frame, providing a mounting support for position sensor 130. This provides greater stability and more accurate positioning.

[0049] Furthermore, if Figure 3 As shown, the positioning fixture is configured with a mounting slot 121, into which the position sensor 130 is mounted. For example, a mounting rod 110 passes through the bottom of the mounting slot 121 to attach to the positioning fixture. The positioning fixture is threadedly connected to the mounting rod 110, facilitating assembly and disassembly of the position sensor 130. The position sensor 130 can be bonded to the mounting slot 121 to maintain its position therein. When disassembly is required, it can be installed and removed together with the positioning fixture.

[0050] In some specific embodiments of the present invention, Figure 3 As shown, each measuring module 10 further includes: an inner nut 21 and an outer nut 22, both of which are threadedly connected to the mounting rod 110, and the inner nut 21 and the outer nut 22 are respectively located on the inner and outer sides of the frame, and adjust the distance that the mounting rod 110 extends out of the outside of the frame.

[0051] Among them, the mounting rod 110 is a screw rod, and the inner nut 21 and the outer nut 22 respectively stop at the inner and outer surfaces of the frame longitudinal beam. By adjusting the distance of the mounting rod 110 extending outward from the outside of the frame by the inner nut 21 and the outer nut 22, the position sensor 130 can be adjusted to a suitable installation position.

[0052] Furthermore, the inner nut 21 and the outer nut 22 may be constructed into a double-nut anti-loosening structure to ensure stable installation of the mounting rod 110 of the measurement module 10 and the vehicle frame.

[0053] In some specific embodiments of the present invention, Figure 4 As shown, the lengths of the multiple mounting rods 110 extending outward from the vehicle frame are different. Position sensors 130 mounted on different mounting rods 110 can perform measurements at different lateral positions, thereby reducing lateral errors and making measurements more accurate.

[0054] In some specific embodiments of the present invention, Figure 3As shown, the position sensor 130 is a wire sensor and includes a sensor body 131 and a collection wire 132. The sensor body 131 is mounted on the measurement and positioning fixture 120. One end of the collection wire 132 is connected to the sensor body 131 and the other end is adapted to extend out of the sensor body 131. The other end of the collection wire 132 is connected to the steering knuckle arm positioning member 200.

[0055] When the position sensor 130 is not in use, the collection cable 132 can be accommodated inside the sensor body 131. The position sensor 130 can obtain the distance between the sensor body 131 and the steering arm positioning piece by extending the collection cable 132 at different measurement positions and connecting the collection cable 132 to the knuckle arm positioning piece.

[0056] In some specific embodiments of the present invention, Figure 2 As shown, the knuckle arm positioning member 200 includes a screw portion 210 and a positioning pin 220. The screw portion 210 is threadedly connected to the knuckle arm 20. The positioning pin 220 is connected to the top of the screw portion 210. The other end of the acquisition cable 132 of the position sensor 130 is configured with a pull ring 140, which is sleeved on the positioning pin 220.

[0057] The screw portion 210 is threadedly connected to the steering knuckle arm 20 to obtain the positioning reference of the steering knuckle arm 20, and the screw portion 210 can appropriately adjust the position of the steering knuckle arm positioning member 200 to ensure the accuracy of the position. The positioning pin 220 extends horizontally and is connected to the pull ring 140 of multiple collection pull lines 132 to accurately measure the position of the steering positioning member. Specifically, the height of the steering knuckle arm positioning member 200 is adjusted, and the distance from the upper surface of the connection hole between the steering knuckle arm 20 and the rear ball joint of the steering longitudinal tie rod to the positioning pin 220 of the knuckle arm positioning tool is recorded. The same method is used to complete another measurement and drawing to obtain the second position point. The line connecting the first position point and the second position point is the axis of the rear ball pin of the steering longitudinal tie rod, which can be compared and analyzed with the design state to determine whether the actual state of the vehicle is different from the design state, thereby achieving the purpose of tool measurement and improving vehicle driving safety and handling comfort.
