[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 A travel luggage walking noise detection device includes a detection component, a drive component, and a limiting component. The detection component includes a housing 1 and a detector 2. The housing 1 has a detection cavity and openings on its front and rear sides. The drive component includes a bearing roller 3, a friction belt 4, and a first motor 5. The bottom wall of the detection cavity is provided with several sets of bearing rollers 3, and the friction belt 4 is sleeved on the outside of several sets of bearing rollers 3. The output end of the first motor 5 passes through the housing 1 and is connected to a set of bearing rollers 3. The limiting component includes a cover 6, a second motor 7, a worm gear 8, a worm 9, a first screw 10, a sliding frame 11, and a slider. The housing 1 is equipped with a cover 6, and a worm gear 9 and two sets of worm wheels 8 are provided inside the cover 6. The worm gear 9 meshes with the two sets of worm wheels 8. The output end of the second motor 7 passes through the cover 6 and is connected to the worm gear 9. Slide frames 11 are symmetrically arranged on the left and right sides of the detection cavity. A first screw 10 is rotatably arranged inside the slide frame 11. The first screw 10 passes through the housing 1 and the cover 6 and is connected to the center of the worm wheel 8. A slider 12 is also provided inside the slide frame 11. The slider 12 is threadedly connected to the first screw 10. A c-shaped limit frame 13 is also provided on the slider 12.

[0022] The bag is placed in the detection chamber, and the second motor 7 (servo motor) is started to drive the worm 9 to rotate. The worm 9 meshes with two sets of worm wheels 8, which drive the first screw 10 to rotate synchronously. Since the slider 12 is threadedly connected to the first screw 10, the two limiting frames 13 (U-shaped structure) on both sides move towards each other along the sliding frame 11 until the two sides of the bag are clamped.

[0023] The first motor 5 (servo motor) starts, driving the bearing roller 3 to rotate, which in turn drives the friction belt 4 to run at a set speed (0.5-5m / s). The wheels of the bag passively roll under the friction of the friction belt 4, simulating a real walking scenario;

[0024] The detector 2 is embedded in the housing 1. As needed, the sound level meter probe of the detector 2 penetrates through the housing 1. As needed, the front and rear openings of the housing 1 can be fitted with soundproof curtains to ensure effective sound reception and to detect the movement of the bag in a vertical position.

[0025] In actual use, the side wall of the limiting frame 13 is also provided with a positioning component, which includes a second screw 14, a handle 15, a bearing 16, a pressure plate 17, and a guide rod 18. The second screw 14 passes through the front side wall of the limiting frame 13 and is connected to the inner ring of the bearing 16. The pressure plate 17 is provided with a groove that connects to the outer ring of the bearing 16. The pressure plate 17 is also provided with a guide rod 18 that passes through the side wall of the limiting frame 13. Rotating the handle 15 of the positioning component with friction texture 20 drives the second screw 14 to rotate, and the bearing 16 drives the pressure plate 17 to move along the guide rod 18, so that the pressure plate 17 is in close contact with the surface of the bag, fixing its thickness direction and ensuring no shaking during testing.

[0026] In practical use, it is often necessary to detect the tilted state of the bag. For this purpose, the limiting component also includes a hook 19. The top wall of the detection cavity is also hinged with a hook 19. One end of the hook 19 is hinged to the bag body 1, and the other end of the hook 19 can be magnetically connected to the bag body 1. When it is necessary to hang the handle of the bag on the hook 19, the horizontal hook 19 is adjusted to a vertical state, the handle of the bag is hung on the hook 19, the first motor 5 is started, the first motor 5 drives the bearing roller 3 to rotate, the friction belt 4 drives the bag wheel to move, and the detector 2 detects the tilted state of the bag.

[0027] In this embodiment, both the first motor 5 and the second motor 7 are servo motors with precise control.

[0028] In this embodiment, support legs 21 are provided at the four corners of the bottom wall of the box 1, and the support legs 21 provide stable support for the box 1;

[0029] It should be noted that when the bag is tilted, the two sets of limit frames 13 are in a higher position, which will not affect the state of the bag.
