[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 5 As shown, a road smoothness detection sensor includes a movable base 1 and a protective component 4. A fixed base 2 is installed at the rear end of the upper surface of the movable base 1, and a push handle 3 is provided on the upper surface of the fixed base 2. The protective component 4 is disposed on the surface of the movable base 1 and includes a fixed frame 401, a limiting slide groove 402, a limiting slider 403, a protective sliding cover 404, a protective box 405, a protective cover 406, a heat dissipation vent 407, a heat dissipation cavity 408, and a dustproof net 409. The fixed frame 401 is disposed on the lower side of the movable base 1, and limiting slide grooves are provided on both sides of the fixed frame 401. The limiting slide groove 402 is slidably connected to the inner side of the limiting slide groove 402, and the outer side of the limiting slide 403 is equipped with a protective slide cover 404. The inner surface of the protective slide cover 404 is slidably connected to the surfaces on both sides of the fixed frame 401. A protective box 405 is installed at the front end of the upper surface of the movable seat 1, and a protective cover 406 is connected to the upper side of the protective box 405 by a hinge. A heat dissipation port 407 is opened on the lower inner surface of the protective box 405, and a heat dissipation cavity 408 is opened at the lower inner end of the protective box 405. Dustproof nets 409 are installed at both ends of the inner side of the heat dissipation cavity 408.

[0024] The specific operation is as follows: During use, the laser displacement sensor 6 and the triaxial accelerometer 7 are set inside the fixed frame 401. Through the sliding connection between the limiting slider 403 and the limiting slide groove 402, the protective sliding cover 404 can be driven to slide along the surface of the fixed frame 401. When the protective sliding cover 404 is slid closed, it can protect the laser displacement sensor 6 and the triaxial accelerometer 7. After the protective sliding cover 404 is opened, the flatness can be detected by the laser displacement sensor 6 and the triaxial accelerometer 7. The digital display controller 5 can be protected by the protective box 405, and heat can be dissipated through the heat dissipation port 407 and the heat dissipation cavity 408. The dustproof net 409 can prevent external dust and other impurities from entering the interior of the protective box 405. After opening the protective cover 406, it can be processed in real time by the digital display controller 5.

[0025] Please refer to Figures 2 to 5The protective box 405 is an integrated structure, and a digital display controller 5 is installed inside the protective box 405. Laser displacement sensors 6 are installed at both ends of the lower side of the fixed frame 401, and a three-axis accelerometer 7 is installed at the lower side of the fixed frame 401. Auxiliary support wheels 8 are installed on both sides of the movable seat 1, and a baffle assembly 9 for removing debris is installed at the front of the movable seat 1. The baffle assembly 9 includes a support plate 901, a fixed plate 902, a fixed shaft 903, a movable cylinder 904, and a pusher baffle 905. The support plate 901 is located at the front of the movable seat 1, and fixed shafts 903 and 904 are installed at both ends of the front of the movable seat 1. The plate 902 is fixed, and a fixed shaft 903 is provided at the front end of the inner surface of the plate 902. A movable cylinder 904 is rotatably connected to the outer surface of the fixed shaft 903. A pusher baffle 905 is installed on the surface of the movable cylinder 904. The baffle assembly 9 also includes a fixed hole 906, a threaded fixing rod 907 and an anti-detachment ring 908. Fixed holes 906 are provided on the surface of the fixed plate 902, the two ends of the fixed shaft 903 and the two ends of the movable cylinder 904. A threaded fixing rod 907 is threadedly connected to the inner side of the fixed hole 906, and an anti-detachment ring 908 is threadedly connected to the lower end of the threaded fixing rod 907.

[0026] The specific operation is as follows: Before testing, the movable cylinder 904 is rotated to the inside of the fixed shaft 903, causing the pusher baffle 905 to rotate to the front. The lower side of the pusher baffle 905 is in contact with the ground. The movable cylinder 904 and the fixed shaft 903 are fixed by the engagement of the threaded fixing rod 907 with the inside of the fixing hole 906. The anti-detachment ring 908 prevents the threaded fixing rod 907 from loosening. When the device is used to test the smoothness of the road, during the forward movement, the pusher baffle 905 pushes away garbage, stones, etc. on the ground, preventing them from affecting the test results. After the pusher baffle 905 rotates and resets, it is supported by the support plate 901. The laser displacement sensor 6 emits a laser beam and receives the reflected signal to measure the change in vertical distance between the road surface and the sensor in real time, thereby accurately quantifying the unevenness of the road surface. The triaxial accelerometer 7 measures the vibration acceleration in the X, Y, and Z directions when the vehicle is moving. Combined with the displacement data, the elevation change of the road longitudinal section is calculated, thereby indirectly evaluating the road surface smoothness. The digital display controller 5 processes the sensor data in real time, calculates the smoothness index, displays the results, and stores the data.

[0027] In summary, as Figures 1 to 5As shown, in use, the road smoothness detection sensor device first rotates the pusher baffle 905 to the front by rotating the movable cylinder 904 and the inner side of the fixed shaft 903, so that the lower side of the pusher baffle 905 is in contact with the ground. The movable cylinder 904 and the fixed shaft 903 are fixed by engaging the threaded fixing rod 907 with the inner side of the fixing hole 906. The anti-detachment ring 908 can prevent the threaded fixing rod 907 from loosening. The laser displacement sensor 6 and the triaxial accelerometer 7 are set inside the fixed frame 401. The protective sliding cover 404 can slide along the surface of the fixed frame 401 by sliding the limit slider 403 and the limit slide groove 402. When the protective sliding cover 404 is closed, it can protect the laser displacement sensor 6 and the triaxial accelerometer 7. When the protective sliding cover 404 is opened, the laser displacement sensor 6 emits a laser beam and receives the reflected signal to measure in real time. The vertical distance between the road surface and the sensor changes, thus accurately quantifying the unevenness of the road surface. The vibration acceleration in the X, Y, and Z directions when the vehicle is moving is measured by the triaxial accelerometer 7. Combined with the displacement data, the elevation change of the road longitudinal section is calculated, thereby indirectly assessing the road surface smoothness. The digital display controller 5 is protected by the protective box 405 and dissipated through the heat dissipation vent 407 and heat dissipation cavity 408. The dustproof net 409 can prevent external dust and other impurities from entering the protective box 405. After opening the protective cover 406, the digital display controller 5 can process the sensor data in real time and calculate the smoothness index, display the results and store the data. During the detection process, the movable seat 1 is pushed forward by pushing the handle 3. During the forward movement, the material pusher baffle 905 pushes away the garbage, stones and other debris on the ground to avoid affecting the detection results.
