[0002] Vehicle body posture refers to the posture or form of the vehicle body when the vehicle is static or running. It is affected by various factors, including the type, design, suspension system, tires, load of the vehicle, etc. Before the vehicle is certified to be put into the market, in order to ensure the stability and accuracy of the vehicle body posture, the height of several vehicle posture points needs to be measured when the vehicle is in different postures (horizontal posture, inclined posture, pitch posture, etc.).

[0003] The measurement process is as follows: place the certified vehicle on the measuring table, the height of the measuring table cannot be changed, control the certified vehicle to adjust to different postures, for each vehicle posture point, use the stylus to aim at the vehicle posture point, and keep the stylus posture unchanged, move the stylus with fixed posture to the height scale, read the reading of the stylus with fixed posture on the height scale, convert the reading, and finally obtain the height of the vehicle posture point. The same steps are performed in sequence until the measurement of the height of different vehicle posture points under different postures of the vehicle is completed.

[0004] However, the conventional measurement method has the following technical defects:

[0042] The present application provides a vehicle posture detection device.

[0043] Please refer to Figure 1 In an embodiment of the present application, the vehicle posture detection device comprises a workbench 10, a measuring scale 20, a rotating assembly 30 and a marking needle assembly 40, the measuring scale 20 is arranged on the workbench 10; the rotating assembly 30 is arranged on the workbench 10 and located on one side of the measuring scale 20; the marking needle assembly 40 is arranged on the rotating assembly 30.

[0044] At present, when measuring the posture height of a vehicle body, multiple to-be-measured vehicle posture points need to be measured under the same vehicle body posture. For example, the front suspension swing arm front suspension bolt center-ground distance, the rear suspension bolt center-ground distance, the front wheel center-ground distance, the rear wheel center-ground distance, etc.

[0045] In the measuring site, the workbench 10 is installed in the pit through the adjusting assembly. The adjusting assembly is used for adjusting the levelness of the workbench 10. Specifically, the workbench 10 adopts a rectangular platform in the embodiment, and the adjusting assembly comprises four telescopic foot supports 50, and one telescopic foot support 50 is arranged at each of four vertex positions of the workbench 10. The telescopic foot support 50 is provided with a matched bolt and nut, and the telescopic function can be realized by adjusting the bolt and nut on the supporting leg. The lengths of the telescopic foot supports 50 at the four vertex positions are adjusted respectively to ensure that the surface height of the workbench 10 reaches the standard and is kept horizontal.

[0046] The vehicle is moved to the workbench 10, and the positions of the measuring scale 20 and the rotating assembly 30 on the workbench 10 are adjusted, so that the measuring scale 20 and the rotating assembly 30 are located on the left and right sides of the vehicle attitude point to be measured respectively.

[0047] The marking needle assembly 40 is rotated to the horizontal state, and the position of the marking needle assembly 40 is adjusted through the rotating assembly 30, so that a certain point of the needle body of the marking needle assembly 40 reaches the vehicle attitude point to be measured, and the needle tip of the marking needle assembly 40 is aligned with the measuring scale 20. The position of the marking needle assembly 40 is fixed, and the reading of the needle tip of the marking needle assembly 40 on the measuring scale 20 at this time is read, which is the height of the vehicle attitude point to be measured. The process of converting the height reading due to the inclination of the marking needle assembly 40 is avoided, and the measurement efficiency is improved.

[0048] After the measurement of the first vehicle attitude point to be measured is completed, the marking needle assembly 40 is adjusted to the initial state, and the above process is repeated to measure the height of the next vehicle attitude point to be measured. When the measurement of all the vehicle attitude points to be measured in the first vehicle attitude state is completed, the vehicle is controlled to enter the next vehicle attitude state to repeat the measurement, until all the vehicle attitude points to be measured in all the vehicle attitude states are measured.

[0049] The technical scheme of the utility model discloses that the rotating assembly 30 can be inclined in multiple directions to adjust the direction of the marking needle assembly 40, so that a certain point of the needle body of the marking needle assembly 40 reaches the vehicle attitude point, and the measurement efficiency is improved because the reading of the needle tip on the height scale does not need to be converted due to the horizontal state of the marking needle assembly 40. Because the reading can be directly read, the height of the measuring scale 20 can be shortened to be less than the height of the vehicle, so that the volume is reduced and the portability is improved.

[0050] In another embodiment, in order to improve the measurement accuracy, the rotating assembly 30 and the measuring scale 20 are fixed on the workbench 10 in a detachable connection mode. Therefore, when measuring different vehicle attitude points to be measured, the positions of the rotating assembly 30 and the measuring scale 20 can be adjusted, so that the rotating assembly 30 and the measuring scale 20 are located on the left and right sides of the vehicle attitude point to be measured.

[0051] Specifically, please refer to Figure 2The rotating assembly 30 specifically comprises a fixing member 31 and a first swing arm 32. The fixing member 31 can be a magnetic fixing seat, and a magnetic switch is used to realize quick disassembly and assembly of the fixing member 31 on the workbench 10, so as to realize quick adjustment of the position of the rotating assembly 30.
