[0001] The utility model relates to the technical field of rotary hub vehicle testing, in particular to a display assembly and a fan for rotary hub testing. Background Art

[0002] At present, when performing a wheel-turn test, the driver display (hereinafter referred to as "driver aid") has a variety of arrangements:

[0003] 1. The driver's assistant is placed on the left or right front of the vehicle through a fixed bracket. This solution can achieve vertical lifting, but this setting has a major disadvantage. Due to the space layout of the test room, the driver's assistant may be in the driver's blind spot;

[0004] Second, the driver's assistant is suspended in front of the vehicle through a cantilever structure, and the driver's assistant is adjusted to a suitable position through the cantilever and bearings. However, this solution has the problem that the driver's assistant is small in size and the driver is prone to fatigue when watching it for a long time. At the same time, if the test vehicle model is high, the cantilever structure must be continuously raised, and there is a great safety risk in the overall structural stability in the flow field of the test laboratory.

[0005] 3. The driver's assistant is fixed above the hub fan through a gantry. Although this structure can solve some of the angle adjustment and structural stability problems, the huge structure requires the laboratory to have a large mobile space. At the same time, the viewing angle of the driver's assistant is different due to the different models being tested.

[0006] Fourth, the driver's auxiliary display is directly connected to the cockpit through a cable. However, due to the small screen size, the driver is prone to fatigue after watching for a long time. In addition, due to the difficulty of fixing and vehicle vibration, the driver needs to hold it tightly with both hands, which increases the labor intensity. In some tests with high sealing requirements, this solution does not meet the test requirements and has great limitations.

[0007] Therefore, the existing rotating hub test has the problem that the display screen position adjustment device is not designed properly, and the vehicle driver may suffer occupational injuries if observing for a long time. Utility Model Content
