Technical Field

[0001] This invention relates to the field of vehicle inspection technology, specifically to a device for dynamically detecting the chassis height of a vehicle based on an Internet of Things (IoT) distance sensor. Background Technology

[0002] With the rapid development of intelligent transportation systems and autonomous driving technologies, the safety, comfort, and intelligence of vehicles are constantly improving. Against this backdrop, accurately measuring key parameters such as vehicle chassis height has become particularly important.

[0003] Chinese patent CN114136218B, authorized and published on March 17, 2023, discloses a vehicle chassis height detection mechanism and device, which includes: a base; a swing assembly including a swing seat and a torsion spring, wherein the swing seat is rotatably connected to the base, and the torsion spring is connected between the swing seat and the base for driving the swing seat to rotate around the axis of the swing seat to reset the swing seat.

[0004] The aforementioned application document describes the use of a detection device connected to a swing seat to detect the height of a vehicle chassis. However, when the device is used outdoors for extended periods, the top of the detection probe becomes covered with a large amount of dust after repeated height measurements, which affects the accuracy of subsequent test results. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device for dynamically detecting vehicle chassis height based on an Internet of Things (IoT) distance sensor, solving the problems mentioned in the background section. To achieve the above objectives, this invention is implemented through the following technical solution: a device for dynamically detecting vehicle chassis height based on an IoT distance sensor, comprising: The detection base has a sealed chamber inside, and a detection probe with an Internet of Things distance sensor is installed inside the sealed chamber. An extraction pipe connected to an air pump is installed on the side of the sealed chamber. The detection base is internally connected to a sensing block via an elastic telescopic block. A cover plate is slidably connected to the inside of the detection base. A transmission component for transmission is assembled between the sensing block and the cover plate. A processing component is assembled inside the sealed chamber. An extraction component is assembled inside the detection base.

[0006] Preferably, the transmission component includes a movable rod fixed to the side of the sensing block, a shaped block fixedly connected to the side of the movable rod, a fixed plate fixedly connected inside the detection base, a connecting rod connected to the side of the fixed plate via a spring, and a second shaped block fixedly connected to the side of the connecting rod. This device design allows the sealed chamber to be resealed when no testing is required, preventing dust from entering when not in use, thereby improving the accuracy of subsequent test results.

[0007] Preferably, the second irregularly shaped block is located on the side of the first irregularly shaped block and is in contact with the first irregularly shaped block.

[0008] Preferably, the cover plate is located on the side of the connecting rod and is fixed to the connecting rod.

[0009] Preferably, the processing component includes a round rod fixed to the bottom of the connecting rod, a toothed rod fixedly connected to the bottom of the round rod, a turntable rotatably connected to the side of the sealing chamber, teeth rotatably connected to the outer side of the turntable via a torsion spring block, a reciprocating lead screw fixedly connected to the side of the turntable, a sliding block threadedly connected to the outer side of the reciprocating lead screw, and a cleaning brush mounted on the top of the sliding block. By configuring the processing component, the cleaning brush can reciprocate a certain distance to clean dust remaining on the top of the detection probe, thereby improving the accuracy of the detection results.

[0010] Preferably, the sliding block is located inside the sealing chamber and is in a sliding connection with the sealing chamber.

[0011] Preferably, the extraction assembly includes a hydraulic chamber assembled inside the detection base. One end of the hydraulic chamber is slidably connected to a force-bearing rod via a piston, and the other end of the hydraulic chamber is slidably connected to an arc-shaped rod via a piston. A second spring is mounted on the side of the force-bearing rod. A through-rotating rod is rotatably connected inside the extraction pipe. A force-bearing plate is fixedly connected to the side of the rotating rod, and a block is fixedly connected to the bottom of the rotating rod. By setting up the extraction assembly, the extraction pipe, which was originally sealed by the block, can be transformed into an open and rotating structure. The dust inside the sealed chamber is then extracted via an air pump and the extraction pipe, further improving the accuracy of the detection results.

[0012] Preferably, the end of the second spring away from the force-bearing rod is fitted onto the inner wall of the hydraulic chamber.

[0013] Preferably, the force-bearing plate is located on the side of the arc-shaped rod and is fixed to the arc-shaped rod.

[0014] This invention provides a device for dynamically detecting the chassis height of a vehicle based on an Internet of Things (IoT) distance sensor. It has the following advantages: (1) The device for dynamically detecting the chassis height of a vehicle based on an IoT distance sensor can squeeze the sensing block when the moving vehicle moves to the detection base. In conjunction with the elastic telescopic block, irregular block one, fixing plate, spring one, connecting rod, irregular block two, and moving rod one, the sealed chamber closed by the cover plate can be converted into an open state, exposing the detection probe, and performing the corresponding height detection operation on the moving vehicle. When no detection is needed, the sealed chamber can be resealed to prevent dust from entering when not in use, thereby improving the accuracy of subsequent detection results. (2) When the connecting rod moves back and forth, the cleaning brush can move back and forth a certain distance in conjunction with the round rod, toothed rod, turntable, torsion spring block, teeth, reciprocating screw, and sliding block, thereby cleaning the dust remaining on the top of the detection probe, thus improving the accuracy of the detection results. (3) The device for dynamically detecting the vehicle chassis height based on the Internet of Things distance sensor can, when the rack moves towards the side closer to the fixed plate, cooperate with the hydraulic chamber, force rod, arc rod, spring 2, rotating rod and force plate to convert the extraction pipe that was originally blocked by the block into an open rotation, and extract the dust in the sealed chamber through the air pump and extraction pipe, thereby further improving the accuracy of the detection results.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Example 1, please refer to Figures 1-4 A device for dynamically detecting the chassis height of a vehicle based on an Internet of Things (IoT) distance sensor, comprising: The detection base 100 has a sealed chamber 200 inside, and a detection probe 300 with an Internet of Things distance sensor is installed inside the sealed chamber 200. An extraction pipe 700 connected to an air pump is installed on the side of the sealed chamber 200. An induction block 402 is connected to the inside of the detection base 100 via an elastic telescopic block 401. A cover plate 408 is slidably connected inside the detection base 100. A transmission component for transmission is assembled between the induction block 402 and the cover plate 408. The transmission component includes a moving rod 409 fixed to the side of the induction block 402. When a moving vehicle moves to the detection base 100, it can squeeze the induction block 402. The squeezed induction block 402 can compress the elastic telescopic block 401 and move downward. The induction block 402 in the downward moving state can drive the moving rod 409 fixedly connected to it to move downward together.

[0024] A shaped block 403 is fixedly connected to the side of the moving rod 409. A fixing plate 404 is fixedly connected inside the detection base 100. A connecting rod 406 is connected to the side of the fixing plate 404 by a spring 405. A cover plate 408 is located on the side of the connecting rod 406 and is fixed to the connecting rod 406. A shaped block 407 is fixedly connected to the side of the connecting rod 406. The shaped block 407 is located on the side of the shaped block 403 and is in contact with the shaped block 403. When the cover plate 408 moves, the sealed chamber 200, which was closed by the cover plate 408, can be opened, exposing the detection probe 300 located inside the sealed chamber 200, and performing corresponding height detection operations on dynamic vehicles; when the vehicle leaves the detection base 100, the sensing block 402 is no longer restricted and can be reset under the action of the elastic telescopic block 401, so that the cover plate 408 closes the sealed chamber 200, preventing dust from entering when the device is not in use, thereby improving the accuracy of subsequent detection results.

[0025] In use, when a moving vehicle moves to the detection base 100, it can squeeze the sensing block 402. The squeezed sensing block 402 compresses the elastic telescopic block 401 and moves downward. The downward-moving sensing block 402 drives the moving rod 409 fixedly connected to it to move downward together. The moving rod 409 drives the irregularly shaped block 403 fixedly connected to it to move downward. The downward-moving irregularly shaped block 403 squeezes the irregularly shaped block 407. The squeezed irregularly shaped block 407 then drives the connecting rod 406 fixedly connected to it. When the vehicle moves, the connecting rod 406 compresses the spring 405 and moves closer to the fixed plate 404. The moving connecting rod 406 can drive the cover plate 408 fixedly connected to it to move, thereby opening the sealed chamber 200 that was closed by the cover plate 408, exposing the detection probe 300 located in the sealed chamber 200, and performing corresponding height detection operations on the dynamic vehicle. When the vehicle leaves the detection base 100, the sensing block 402 is no longer restricted and can be reset under the action of the elastic telescopic block 401, so that the cover plate 408 closes the sealed chamber 200.

[0026] Example 2, please refer to Figures 1-6 Based on Embodiment 1, the sealed chamber 200 is equipped with a processing component 500. The processing component 500 includes a round rod 501 fixed to the bottom of the connecting rod 406, and a toothed rod 502 is fixedly connected to the bottom of the round rod 501. When the connecting rod 406 moves towards the side closer to the fixed plate 404, it can drive the round rod 501 fixedly connected to the connecting rod 406 to move together. The round rod 501 in the moving state can drive the toothed rod 502 fixedly connected to it to move towards the side closer to the fixed plate 404.

[0027] A turntable 503 is rotatably connected to the side of the sealed chamber 200. A toothed joint 505 is rotatably connected to the outer side of the turntable 503 via a torsion spring block 504. A reciprocating screw 506 is fixedly connected to the side of the turntable 503. A sliding block 507 is threadedly connected to the outer side of the reciprocating screw 506. The sliding block 507 is located inside the sealed chamber 200 and is in a sliding connection with it. A cleaning brush 508 is mounted on the top of the sliding block 507. When the sliding block 507 reciprocates a certain distance horizontally, it drives the cleaning brush 508 on its top to reciprocate a certain distance, cleaning the dust remaining on the top of the detection probe 300, thereby improving the accuracy of the detection results.

[0028] In use, based on Embodiment 1, when the connecting rod 406 moves towards the side closer to the fixed plate 404, it can drive the round rod 501 fixedly connected to the connecting rod 406 to move together. The round rod 501 in the moving state can drive the toothed rod 502 fixedly connected to it to move towards the side closer to the fixed plate 404. At this time, the toothed rod 505 is restricted by the turntable 503 and cannot rotate around the torsion spring block 504 as the axis. This allows the toothed rod 502 to drive the turntable 503 to rotate counterclockwise at a certain angle during the process of moving towards the side closer to the fixed plate 404. When the toothed rod 502 and the round rod 501 are reset with the connecting rod 406, the toothed rod 505 is no longer restricted by the turntable 503 and rotates clockwise at a certain angle around the torsion spring block 504 as the axis. This prevents the rack 502 from driving the turntable 503 to rotate via the teeth 505. As a result, during the reciprocating movement of the rack 502 along the connecting rod 406, the turntable 503 rotates intermittently counterclockwise. The rotating turntable 503 drives the reciprocating screw 506, which is fixedly connected to it, to rotate. Meanwhile, the sliding block 507, threaded onto the outside of the reciprocating screw 506, is simultaneously restricted by the sealing chamber 200, which is slidably connected to it. This causes the sliding block 507 to reciprocate a certain distance horizontally during the rotation of the reciprocating screw 506. The moving sliding block 507 then drives the cleaning brush 508 mounted on its top to reciprocate a certain distance, cleaning the dust remaining on the top of the detection probe 300.

[0029] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, the detection base 100 is internally equipped with a extraction assembly 600. The extraction assembly 600 includes a hydraulic chamber 601 installed inside the detection base 100. One end of the hydraulic chamber 601 is slidably connected to a force-bearing rod 602 via a piston. When the rack 502 moves towards the side closer to the fixed plate 404, it can compress the force-bearing rod 602, and the compressed force-bearing rod 602 can move laterally.

[0030] The other end of the hydraulic chamber 601 is slidably connected to an arc-shaped rod 603 via a piston. When the oil in the hydraulic chamber 601 is squeezed and flows towards the side closer to the arc-shaped rod 603, it can drive the arc-shaped rod 603, which is slidably connected to the hydraulic chamber 601 via the piston, to move out of the hydraulic chamber 601.

[0031] A second spring 604 is mounted on the side of the force-bearing rod 602. The end of the second spring 604 away from the force-bearing rod 602 is mounted on the inner wall of the hydraulic chamber 601. A through-type rotating rod 605 is rotatably connected inside the extraction pipe 700. A force-bearing plate 606 is fixedly connected to the side of the rotating rod 605. The force-bearing plate 606 is located on the side of the arc-shaped rod 603 and is fixed to the arc-shaped rod 603. When the arc-shaped rod 603 is moved out of the hydraulic chamber 601, it can drive the force-bearing plate 606 fixedly connected to it to rotate at a certain angle, so that the force-bearing plate 606 drives the rotating rod 605 fixedly connected to it to rotate at a certain angle together.

[0032] A blocking block 607 is fixedly connected to the bottom of the rotating rod 605. When the rotating rod 605 rotates at a certain angle, it can drive the blocking block 607 fixedly connected to it to rotate, turning the extraction pipe 700, which was originally closed by the blocking block 607, into an open rotation. Through the air pump and the extraction pipe 700, the dust in the sealed chamber 200 is extracted, further improving the accuracy of the test results.

[0033] In use, based on Embodiments 1 and 2, when the rack 502 moves towards the side closer to the fixed plate 404, it can compress the force-bearing rod 602. The compressed force-bearing rod 602 can then move laterally. In conjunction with the hydraulic chamber 601, which is slidably connected to the force-bearing rod 602 via a piston, the force-bearing rod 602, during its movement, compresses the oil originally stored in the hydraulic chamber 601. The compressed oil flows towards the side closer to the arc-shaped rod 603, causing the arc-shaped rod 603, which is slidably connected to the hydraulic chamber 601 via a piston, to move out of the hydraulic chamber 601. The arc-shaped rod 603 is in a moving state. This will cause the force plate 606, which is fixedly connected to it, to rotate at a certain angle, so that the force plate 606 will drive the rotating rod 605, which is fixedly connected to it, to rotate at a certain angle. The rotating rod 605, which is in a rotating state, can drive the block 607, which is fixedly connected to it, to rotate, so that the extraction pipe 700, which was originally closed by the block 607, is opened and rotated. The dust in the sealed chamber 200 is extracted through the air pump and the extraction pipe 700. When the toothed rod 502 is reset, the force rod 602 is no longer restricted and can be reset under the action of the second spring 604. Similarly, the block 607 is reset.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
