[0037] As Figures 1 - 3 shown, an arc track unit for a driver attention monitoring system test mainly includes: a first arc tube 1, a second arc tube 2, a first connector 3, and a second connector 4.

[0038] The first arc tube 1 and the second arc tube 2 are arranged at intervals, and both the first arc tube 1 and the second arc tube 2 are formed by bending rectangular tubes. Moreover, the cross-section of the first arc tube 1 is the same as that of the second arc tube 2, that is, the first arc tube 1 and the second arc tube 2 are made of rectangular tubes of the same specification, which is convenient for obtaining materials. Among them, the length of the first arc tube 1 is less than that of the second arc tube 2, and the center of the first arc tube 1 coincides with the center of the second arc tube 2, that is, they are concentrically arranged. During the test, the lighting module needs to slide along the first arc tube 1 and the second arc tube 2, that is, slide along the centers of the first arc tube 1 and the second arc tube 2.

[0039] Below the two ends of the first arc-shaped pipe 1 and below the two ends of the second arc-shaped pipe 2, a support foot 10 is provided. The four support feet 10 respectively support at the four corners of the arc-shaped track unit, and the entire arc-shaped track unit can be supported.

[0040] In the first connecting piece 3 and the second connecting piece 4, one end of the first connecting piece 3 is detachably connected to one end of the first arc-shaped pipe 1, and the other end of the first connecting piece 3 is detachably connected to one end of the second arc-shaped pipe 2 to connect one end of the first arc-shaped pipe 1 and the second arc-shaped pipe 2. One end of the second connecting piece 4 is detachably connected to the other end of the first arc-shaped pipe 1, and the other end of the second connecting piece 4 is detachably connected to the other end of the second arc-shaped pipe 2 to connect the other end of the first arc-shaped pipe 1 and the second arc-shaped pipe 2. Both ends of the first connecting piece 3 and the second connecting piece 4 are detachably connected to the first arc-shaped pipe 1 and the second arc-shaped pipe 2, which is convenient for detaching the first connecting piece 3 and the second connecting piece 4 from the first arc-shaped pipe 1 and the second arc-shaped pipe 2. After being detached, the space occupied by the arc-shaped track unit is small.

[0041] Specifically, as Figure 3 and Figure 4 shown, the structures of the first connecting piece 3 and the second connecting piece 4 are the same, and the connection positions of the first connecting piece 3 and the second connecting piece 4 on the first arc-shaped pipe 1 and the second arc-shaped pipe 2 can be interchanged, which is convenient for installation, does not require an anti-misalignment structure, and is also convenient for manufacturing. Among them, both the first connecting piece 3 and the second connecting piece 4 include a connecting plate and two rectangular joints 34 respectively fixedly connected to both ends of the connecting plate. The two rectangular joints 34 can be fixed by welding with the connecting plate, or can also be fixed by means of bolts, screws, etc.

[0042] The cross-sections of the first arc-shaped pipe 1 and the second arc-shaped pipe 2 are both rectangular, that is, both are formed by bending rectangular pipes into pipe fittings with a certain curvature, and the radii of the first arc-shaped pipe 1 and the second arc-shaped pipe 2 are not equal. The first connecting piece 3 is detachably connected to the first arc-shaped pipe 1 and the second arc-shaped pipe 2 respectively through the rectangular joints 34 at both ends. The second connecting piece 4 is detachably connected to the first arc-shaped pipe 1 and the second arc-shaped pipe 2 respectively through the rectangular joints 34 at both ends. Specifically, the rectangular joint 34 is detachably inserted into the end of the first arc-shaped pipe 1 or the second arc-shaped pipe 2, that is, the outer dimension of the rectangular joint 34 is less than or equal to the size of the rectangular inner hole of the first arc-shaped pipe 1 and the second arc-shaped pipe 2 to ensure that the rectangular joint 34 can be inserted into the first arc-shaped pipe 1 and the second arc-shaped pipe 2. Another implementation method is that the rectangular joint 34 is detachably sleeved on the end of the first arc-shaped pipe 1 or the second arc-shaped pipe 2, that is, the size of the inner rectangular hole of the rectangular structure is slightly larger than the outer rectangular size of the first arc-shaped pipe 1 and the second arc-shaped pipe 2 to ensure convenient sleeving of the rectangular joint 34.

[0043] During actual use, both ends of the first connecting member 3 are detachably connected to the two ends of the first arc-shaped pipe 1 and the second arc-shaped pipe 2 respectively, connecting the first arc-shaped pipe 1 and the second arc-shaped pipe 2. Both ends of the second connecting member 4 are detachably connected to the other ends of the first arc-shaped pipe 1 and the second arc-shaped pipe 2 respectively, connecting the first arc-shaped pipe 1 and the second arc-shaped pipe 2. When transportation or storage is required, the first connecting member 3 and the second connecting member 4 can be detached from both ends of the first arc-shaped pipe 1 and the second arc-shaped pipe 2 respectively, and the arc-shaped track unit can be disassembled as a whole, effectively reducing the space occupied by the arc-shaped track unit.

[0044] Preferably, first inclined surfaces 12 are provided at both ends of both the first arc-shaped pipe 1 and the second arc-shaped pipe 2, and a second inclined surface 35 is provided on the rectangular joint 34. When the rectangular joint 34 is connected to the end of the first arc-shaped pipe 1 or the second arc-shaped pipe 2, the second inclined surface 35 can slide along the first inclined surface 12. That is, the second inclined surface 35 cooperates with the first inclined surface 12, facilitating the insertion of the rectangular joint 34 into the ends of the first arc-shaped pipe 1 and the second arc-shaped pipe 2, and the insertion is convenient. Specifically, four first inclined surfaces 12 are provided along the circumferences of the end faces of both the first arc-shaped pipe 1 and the second arc-shaped pipe 2, and four second inclined surfaces 35 are provided along the circumference of the rectangular joint 34. The cooperation between the second inclined surface 35 and the first inclined surface 12 has a guiding effect during assembly, facilitating the insertion and assembly of the rectangular joint 34 with the two arc-shaped pipes.

[0045] In this solution, the arc-shaped track unit can be disassembled, and the disassembly and assembly are convenient. The space occupied after disassembly is small, which is convenient for transportation and storage.
