[0001] The utility model relates to the technical field of automobile testing devices, in particular to a lifting mechanism used for testing a driver attention monitoring system. Background Art

[0002] Some cars are equipped with a driver attention monitoring system that can monitor the driver's driving behavior. When the driver makes some actions that affect driving, such as making a phone call or smoking, the system will issue an alarm message.

[0003] The reliability of the system is tested through the driver attention monitoring system test. During the test, the light simulation device shines on the driver in the cab from various angles and heights. Therefore, the light simulation device is set on the lifting mechanism, and the lifting mechanism drives the light simulation device to move up and down.

[0004] For example, the patent with the announcement number "CN117133096B" discloses a test system and test method for a driver attention monitoring system. In this solution, the lighting module includes a mounting frame, a first lifting bracket, a second lifting bracket, a light-emitting component and a controller, wherein: the first lifting bracket is arranged on the mounting frame, and the first motor can drive the first lifting bracket to move up and down through the first cable; the second lifting bracket is arranged on the first lifting bracket, and the first lifting bracket can drive the second lifting bracket to move up and down through the second cable; the light-emitting component (light simulation device) is arranged on the second lifting bracket. When the test is completed, the second lifting bracket and the two first lifting brackets are removed from the device, but they are stored in a messy manner after removal, resulting in the need to find the first lifting bracket or the second lifting bracket frequently during subsequent tests.

[0036] like Figure 1-Figure 3 As shown, a lifting mechanism for testing a driver attention monitoring system can drive a light assembly to perform lifting movements, and mainly includes: a mounting frame 1, a first bracket 2 and a second bracket 3.

[0037] The first bracket 2 and the second bracket 3 are arranged at intervals, and the light assembly can be installed on the mounting frame 1. When the mounting frame 1 is lifted and lowered relative to the first bracket 2 and the second bracket 3 during the test, the light assembly on the mounting frame 1 is lifted and lowered together with the mounting frame 1. Specifically, one end of the mounting frame 1 is arranged on the first bracket 2, and the other end of the mounting frame 1 is arranged on the second bracket 3, and the mounting frame 1 can be lifted and lowered relative to the first bracket 2 and the second bracket 3, thereby driving the light assembly to be lifted and lowered on the first bracket 2 and the second bracket 3. Among them, the first bracket 2 and the second bracket 3 each include two side rods 21 and end rods 22 respectively connected to the two ends of the two side rods 21, and the mounting frame 1 can be lifted and lowered along the side rods 21. Two rows of rollers 13 are arranged at both ends of the mounting frame 1, and the two rows of rollers 13 at one end of the mounting frame 1 are respectively movably arranged on both sides of the side rod 21 of the first bracket 2; the two rows of rollers 13 at the other end of the mounting frame 1 are respectively movably arranged on both sides of the side rod 21 of the second bracket 3. That is, two rollers 13 are movably provided on both sides of each side rod 21 on the first bracket 2 and the second bracket 3 on the mounting frame 1. When the mounting frame 1 is lifted or lowered relative to the first bracket 2 and the second bracket 3, the rollers 13 can roll to reduce friction and ensure smooth lifting and lowering movement. In addition, each side rod 21 has rollers 13 on both sides, and the rollers 13 also have a limiting function to prevent the mounting frame 1 from detaching from the first bracket 2 and the second bracket 3.

[0038] A plurality of hooks 10 are provided on the mounting frame 1. When the mounting frame 1 is removed from the first bracket 2 and the second bracket 3, the first bracket 2 and the second bracket 3 can be hooked on the hooks 10. Specifically, the hooks 10 are provided on the back side of the mounting frame 1 to avoid affecting the installation of the lighting assembly. Two hooks 10 are provided at each end close to the mounting frame 1. The hooks 10 at both ends of the mounting frame 1 are symmetrically arranged to ensure the force balance of the mounting frame 1. The hooks 10 of this embodiment are arranged in an L shape, and a guide slope 101 is provided on the top of the L-shaped hook 10. When the first bracket 2 and the second bracket 3 are hooked on the hook 10, the guide slope 101 can facilitate the insertion of the first bracket 2 and the second bracket 3.

[0039] In actual use, this embodiment is provided with a plurality of hooks 10 on the mounting frame 1. When the mounting frame 1 is removed from the first bracket 2 and the second bracket 3, the first bracket 2 and the second bracket 3 can be hooked on the hooks 10 on the mounting frame 1, so as to avoid the first bracket 2, the second bracket 3 and the mounting frame 1 being placed in a disorderly manner. When a test is needed next time, it is also convenient to assemble the lifting mechanism.

[0040] like Figure 2 and Figure 3As shown, the hook 10 and the mounting frame 1 can be fixed by welding, in which case the hook 10 cannot be adjusted. When the first bracket 2 and the second bracket 3 are clamped on the hook 10, only the two hooks 10 at one end of the mounting frame 1 are clamped with the end rods 22 on the first bracket 2 and the second bracket 3, and the two hooks 10 at the other end of the mounting frame 1 are not clamped.

[0041] like Figure 4 and Figure 5 As shown, the hook 10 can also be detachably fixed to the mounting frame 1 by a fixing bolt 12, and the hook 10 can be rotated and adjusted on the mounting frame 1. Specifically, the mounting frame 1 is provided with a bolt through hole 11, and the hook 10 is provided with a threaded hole. The fixing bolt 12 passes through the bolt through hole 11 and is threadedly connected in the threaded hole to fix the hook 10 on the mounting frame 1. During use, when the first bracket 2 and the second bracket 3 are both clamped on the hook 10 side by side, the hook 10 at one end of the mounting frame 1 is detachably clamped on the end rod 22 of both the first bracket 2 and the second bracket 3. The hook 10 at the other end of the mounting frame 1 is detachably clamped on the side rod 21 of both the first bracket 2 and the second bracket 3. Furthermore, when the first bracket 2 and the second bracket 3 are clamped on the hook 10 side by side, the top end of the first bracket 2 is in contact with the bottom end of the second bracket 3, and the bottom end of the first bracket 2 is in contact with the top end of the second bracket 3, that is, the first bracket 2 and the second bracket 3 are inverted head to tail to avoid mutual interference between the side structures of the two. The inversion can make the protruding structures avoid each other.

[0042] During actual use, when the hook 10 of this embodiment is installed by the fixing bolt 12, the hook 10 can be rotated and adjusted on the mounting frame 1. The hook 10 at one end of the mounting frame 1 is clamped on the end rod 22 of the first bracket 2 and the second bracket 3, and the hook 10 at the other end of the mounting frame 1 is clamped on the side rod 21 of the first bracket 2 and the second bracket 3, which can further ensure that the clamping and fixing are reliable.

[0043] In this solution, after the mounting frame 1 is removed from the first bracket 2 and the second bracket 3, the first bracket 2 and the second bracket 3 can be clamped on the hook 10 on the mounting frame 1 to avoid the first bracket 2, the second bracket 3 and the mounting frame 1 being placed in a disorderly manner. When the test is needed next time, it is also convenient to assemble the lifting mechanism.
