Description

Technical Field

[0001] This utility model relates to the field of automotive measuring tools, and in particular to an automotive body height measuring tool. Background Technology

[0002] In automobile manufacturing, the vehicle's height needs to be adjusted to ensure consistent left and right height and to maintain optimal damping and stiffness values ​​for the suspension system. Current methods involve driving the vehicle to a pit inspection station, where two workers work together. One worker in the pit loosens the eccentric bolts connecting the linkages, then gradually adjusts them. Meanwhile, a worker above the pit determines if the vehicle's height is aligned. Once aligned, the worker in the pit tightens the bolts. This process is inconvenient, requires two people, and relies on subjective judgment for height adjustment, resulting in low precision.

[0003] Therefore, a vehicle height measuring tool is needed to measure the vehicle's height. A published Chinese patent, CN203240991U, describes a height measurement method using a height indicator, a connecting device, and a qualified interval label. However, this patent has several drawbacks. First, the connecting device uses a three-pronged structure to connect to the wheel hub, but this structure is fixed, its radius is not adjustable, and the angle between the three prongs is also fixed, limiting its applicability. Second, additional connectors are needed to link the connecting device to the wheel hub. Finally, the height still needs to be determined manually by visually inspecting the label, which is affected by lighting and viewing angle, resulting in insufficient accuracy. Utility Model Content

[0004] The purpose of this utility model is to solve the following technical problems: the existing connection device has a three-claw structure that cannot be adjusted and is used in a single way, requires an additional connecting part to connect to the wheel hub, and still needs to be determined by manually visually checking the label paper, which is not accurate enough.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: According to one aspect of this utility model, a vehicle body height measuring tool is provided, comprising: a wheel hub connecting plate, the wheel hub connecting plate having multiple sets of positioning hole groups, each set of positioning hole groups including multiple positioning holes, and the multiple sets of positioning hole groups being distributed in multiple layers along the radial direction of the wheel hub connecting plate to adapt to wheel hubs of different diameters; a sleeve assembly, the number of which is at least three, each sleeve assembly being detachably inserted into a selected positioning hole via a plug rod; a height indicator rod, which is a long rod-shaped structure; a slider, which is sleeved on the rod body of the height indicator rod and can slide along the length direction of the rod body; a stop rod, which passes through a hole opened in the slider; wherein, a longitudinally extending groove is opened on the rod body of the height indicator rod, and the rod body portion of the stop rod is accommodated in the groove and can slide along it; by moving the slider to drive the stop rod, the end of the stop rod can abut against the arc-shaped reference surface of the vehicle body wheel arch.

[0006] Optionally, the sleeve assembly includes a sleeve body and a plug rod, one end of which is inserted into a positioning hole in the hub connecting plate, and the other end is connected to the sleeve body.

[0007] Optionally, the end of the sleeve body is formed with an internal thread for engaging with a screw on the wheel hub, thereby fixing the entire measuring tool to the vehicle wheel hub.

[0008] Optionally, the lower end of the height indicator rod is movably connected to the center of the hub connecting plate via a hinge mechanism, so that the height indicator rod can rotate relative to the hub connecting plate.

[0009] Optionally, the hinge mechanism includes a connecting rod, one end of which is detachably connected to the center of the hub connecting plate, and the other end of which is provided with a connecting hole, through which a height indicator rod passes to achieve connection with the connecting rod.

[0010] Optionally, the slider is provided with a locking mechanism for pressing and fixing the slider to the height indicator rod.

[0011] Alternatively, the locking mechanism is a screw screwed onto the slider, the end of which abuts against the body of the height indicator rod when tightened.

[0012] Optionally, the height indicator may also be provided with a scale or a qualified range label for indicating the height.

[0013] Optionally, the hub connecting disc is a disc-shaped or three-claw-shaped structure, and the multi-layered positioning hole group is a group of multiple concentric circular holes centered on the center of the hub connecting disc.

[0014] The advantages of this utility model are as follows: the design of multiple sets of positioning holes can adapt to hubs of different diameters, significantly increasing the range of applications of the measuring tool and solving the problems of fixed connection device structure and inability to adjust radius in the prior art; the detachable design of the sleeve assembly facilitates installation and disassembly, simplifying the operation process; the combination design of the slider and stop bar makes height measurement more accurate, no longer relying on manual visual judgment, thus improving measurement accuracy; the overall structure is simplified, and it can be directly connected to the hub without additional connecting parts, reducing the complexity of use.
