Description

Technical Field

[0001] The utility model relates to the technical field of automobile maintenance and detection, in particular to a non-contact automobile ground clearance measuring device. Background Art

[0002] The minimum ground clearance of a car refers to the shortest distance between the lowest point of the car other than the wheels and the supporting plane when the car is fully loaded and stationary. It is one of the important indicators for measuring the passability of the car. This parameter is used to characterize the ability of the car to pass over obstacles such as stones and stumps without collision, and is also an important reference indicator for customers to choose cars. The traditional car ground clearance measurement usually relies on tools such as a square ruler or a modified contact ground clearance measuring device to directly contact the parts under the car body. This method is inconvenient to operate and inefficient. It may also lead to large measurement errors due to the subjective judgment errors of the measurer. It is especially inconvenient when the bottom shape of some vehicles is more complex and difficult to accurately reach. At the same time, the inspectors generally need to manually place the measuring device below the vehicle chassis, which poses certain safety risks. Utility Model Content

[0016] In order to better understand the improvements made by the present invention relative to the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] like Figure 1 As shown in FIG. 4 , a non-contact vehicle ground clearance measuring device is mainly composed of a laser level marking instrument 1, a lifting platform 2 and a ruler 3.

[0018] The lifting platform 2 is composed of a placement platform 21, a lifting member 22 and a base 23 arranged in sequence from top to bottom. The laser horizontal marking instrument 1 is preferably fixedly installed on the placement platform 21 by bolt connection. The ruler 3 is installed on the side of the lifting platform 2 and is close to the lifting platform 2. The ruler is provided with a scale. In order to obtain the measurement data more intuitively, the bottom of the ruler 3 is the starting point of the scale. The side of the lifting platform 2 is provided with a mounting socket, and the ruler 3 is fixedly installed in the mounting socket. When testing, in order to meet the height requirements of different car ground clearances, the ruler 3 can be replaced with different scales or ranges. The laser horizontal marking instrument 1 marks and positions the scale 3 by laser, thereby realizing non-contact measurement of the car ground clearance. In order to facilitate lifting and stabilize the laser horizontal marking instrument 1 to reduce shaking during the lifting process, the lifting platform 2 is a manual lifting platform, and the lifting member 22 is lifted by a scissor fork to achieve rapid adjustment and precise height control.

[0019] like Figure 5 As shown, when measuring the ground clearance of a car, first park the car on a flat surface, then place the non-contact ground clearance measuring device on the flat surface on any side of the vehicle, turn on the laser level scriber 1, project a horizontal laser beam, place a rectangular cardboard on the other side of the vehicle opposite to the measuring device, or place one side of the vehicle close to the wall, and observe the beam line projected by the laser level scriber 1 on the wall after passing through the vehicle chassis. In addition to the beam being blocked by the tire, if a new blockage occurs during the upward translation of the laser beam, it means that the laser beam has detected an obstacle at the bottom of the vehicle. At this time, check the scale value corresponding to the laser beam on the ruler 3 to obtain the ground clearance height value of the measured vehicle. Since the bottom end of the ruler 3 is the starting point of the scale, when testing, directly reading the height of the laser beam of the laser level scriber 1 on the ruler 3 is the height of the ground clearance of the car.

[0020] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
