Description

Technical Field

[0001] This utility model belongs to the field of vehicle inspection technology and relates to a vehicle chassis height detection device. Background Technology

[0002] In modern logistics and transportation systems, large trucks serve as crucial carriers for cargo transport, and their driving safety is paramount. When a large truck is fully loaded, the cargo causes the vehicle chassis to lower, making chassis height a significant factor affecting driving safety and maneuverability. Appropriate chassis height ensures smooth passage for large trucks under various road conditions, preventing scraping and collisions between the chassis and road obstacles.

[0003] Currently, methods for detecting the chassis height of large trucks have many shortcomings. Traditional manual inspection uses tools such as measuring tapes, which is cumbersome and prone to errors. Manual operation is also greatly affected by subjective factors, as different inspectors have different measurement methods and judgment standards, which can easily lead to measurement errors. Big data inspection solutions suffer from high development and maintenance costs.

[0004] In summary, existing technologies for detecting the chassis height of heavy trucks cannot meet the demands for efficient, accurate, and low-cost detection. There is an urgent need to develop a new type of vehicle chassis height detection device to overcome the shortcomings of existing technologies, improve the reliability and convenience of heavy truck chassis height detection, and ensure the safe driving and efficient transportation of heavy trucks. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a vehicle chassis height detection device. The technical problem this utility model aims to solve is to improve the reliability and convenience of detecting the chassis height of large trucks, thereby ensuring the safe driving and efficient transportation of large trucks.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A vehicle chassis height detection device includes a detection device body, which includes an operating component and a detection component for detecting the vehicle chassis height.

[0008] The detection component includes a gear disk, on the surface of which two sets of rotating rods are fixedly connected. The two ends of the rotating rods are movably fitted with head limit seats and tail limit seats for limiting.

[0009] A moving rod is fixedly connected to the end of the rotating rod away from the gear disk. A positioning bayonet is integrally formed on the body of the moving rod. The positioning bayonet has a U-shaped bayonet design. The internal part of the positioning bayonet holds a connecting shaft. A lifting rod is fixedly connected above the connecting shaft. A scale is opened on the surface of the lifting rod. The lifting rod is slidably installed inside the insert rod. A moving groove for the movement of the positioning bayonet is opened on the side of the insert rod. The operating component is connected to the gear disk.

[0010] The working principle of this invention is as follows: When the gear disc rotates, the rotating rod connected to its surface rotates accordingly. The moving rod connected to the end of the rotating rod away from the gear disc also rotates. The positioning slot at the top of the moving rod is U-shaped, and the connecting shaft at the bottom of the lifting rod is clamped inside. When the moving rod rotates, it drives the lifting rod to move up and down inside the insert rod through the connecting shaft. The moving groove on the side of the insert rod provides space for the movement of the positioning slot. During the up and down movement of the lifting rod, the scale on its surface can display the distance the lifting rod has moved. After the device is moved under the vehicle, the lifting rod is raised by operating the handle until its top touches the vehicle chassis. At this time, the scale value on the dial is the height of the vehicle chassis from the ground, thus completing the detection of the vehicle chassis height. This invention replaces traditional manual tape measure measurement, avoids measurement errors caused by subjective factors of manual operation, significantly improves the accuracy of the detection results, and has a simple structural design that does not require the support of complex big data systems, reducing development and maintenance costs.

[0011] The operating components include a fixed base plate and a handle. The handle is L-shaped, and the inflection point of the handle is hinged to the fixed base plate via a first pin. One end of a receiving rod is hinged to the top of the handle via a second pin, and the other end of the receiving rod is hinged to a push rod via a third pin. A positioning sleeve for limiting the push rod is fixedly connected above the fixed base plate. The push rod slides inside the positioning sleeve. A toothed plate is fixedly connected to the top of the push rod, and the bottom surface of the toothed plate is provided with evenly distributed teeth.

[0012] With the above structure, the handle of the operating component is L-shaped, and its inflection point is hinged to the fixed base plate via a first pin. When the handle is moved up or down, the top of the handle drives the receiving rod to move via a second pin, and the other end of the receiving rod pushes the push rod to slide back and forth within the positioning sleeve via a third pin. The retaining plate at the top of the push rod moves accordingly, and the retaining teeth on the bottom surface of the retaining plate mesh with the gear disk, thereby driving the gear disk to rotate and achieving the purpose of driving the entire detection component to move. The entire detection process is simple to operate and improves detection efficiency.

[0013] The toothed plate is located on the upper surface of the gear disk, and the teeth mesh with the gear disk.

[0014] With the above structure, the teeth of the locking teeth and the gears of the gear disk directly mesh to form a rigid transmission structure, avoiding the slippage or loosening problems of traditional belt and chain transmission methods, and ensuring that the operation of the lever can be accurately converted into the rotation of the gear disk.

[0015] The operating components are fixedly mounted on a fixed chassis, and a first set of omnidirectional wheels for movement is installed below the fixed chassis. A connecting base plate and a supporting base plate are fixedly connected to the bottom ends of the head limit seat and the tail limit seat, respectively. Both the connecting base plate and the supporting base plate are fixedly connected to the side of the fixed chassis, and a second set of omnidirectional wheels is installed at the bottom of the insertion rod.

[0016] With the above structure, the operating components in the main body of the detection device are fixedly mounted on a fixed chassis. The first set of casters under the fixed chassis and the second set of casters at the bottom of the insertion rod are kept on the same horizontal plane. When the device is pushed, the first and second sets of casters can rotate flexibly, allowing the entire device to move under the vehicle to prepare for chassis height detection. This provides stable support and convenient movement for accurate chassis height detection.

[0017] The lifting rod is a three-dimensional rectangular shape and is fitted into the internal through hole of the insertion rod. The moving groove on the side of the insertion rod extends vertically. The length of the moving groove is greater than the maximum lifting stroke of the lifting rod. The U-shaped opening of the positioning bayonet is engaged with the surface of the connecting shaft and can slide up and down along the moving groove.

[0018] The above structure ensures that the scale lines on the dial always remain vertical, avoiding reading deviations caused by instability during the lifting process of the lifting rod, and guaranteeing the accuracy of the height detection value.

[0019] Compared with existing technologies, this vehicle chassis height detection device has the following advantages:

[0020] 1. This utility model replaces traditional manual tape measure measurement with a mechanical linkage structure between the operation component and the detection component, avoiding measurement errors caused by subjective factors of manual operation, greatly improving the accuracy of the detection results, and the structure design is simple, requiring no complex big data system support, thus reducing development and maintenance costs.

[0021] 2. This utility model is equipped with a first universal wheel set and a second universal wheel set, which can be flexibly moved under the vehicle. During operation, simply turn the handle, and the lifting rod will be driven to rise and fall through the meshing transmission of the toothed plate and the gear disc. The scale on the surface of the lifting rod can directly display the chassis height. The entire inspection process is simple to operate and improves inspection efficiency.

[0022] 3. All components of this utility model are installed on a fixed chassis, with a compact and stable structure. The universal wheel set ensures the flexibility of the device's movement, allowing the detection device to easily reach a suitable position under the vehicle, providing stable support and convenient movement conditions for accurately detecting the chassis height.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figures 1-5 As shown, a vehicle chassis height detection device includes a detection device body 1, which includes an operating component 2 and a detection component 3 for detecting the vehicle chassis height.

[0031] The operating component 2 includes a fixed base plate 21 and a handle 22. The handle 22 is L-shaped, and the inflection point of the handle 22 is hinged to the fixed base plate 21 by a first pin 23.

[0032] The top of the handle 22 is hinged to one end of the receiving rod 24 via the second pin 25, and the other end of the receiving rod 24 is hinged to the push rod 26 via the third pin 27. A positioning sleeve 28 for limiting the push rod 26 is fixedly connected above the fixed base plate 21. The push rod 26 slides inside the positioning sleeve 28. A toothed plate 29 is fixedly connected to the top of the push rod 26. The bottom surface of the toothed plate 29 is provided with evenly distributed teeth 210.

[0033] It should be noted that the toothed plate 29 is located on the upper surface of the gear disk 31, and the toothed plate 210 meshes with the gear disk 31.

[0034] In the specific implementation scheme, the handle 22 of the operating component 2 is L-shaped, and its inflection point is hinged to the fixed base plate 21 via the first pin 23. When the handle 22 is moved up or down, the top of the handle 22 drives the receiving rod 24 to move via the second pin 25, and the other end of the receiving rod 24 pushes the push rod 26 to slide back and forth within the positioning sleeve 28 via the third pin 27. The toothed plate 29 at the top of the push rod 26 moves accordingly, and the teeth 210 on the bottom surface of the toothed plate 29 mesh with the gear disk 31, thereby driving the gear disk 31 to rotate.

[0035] The detection component 3 includes a gear disk 31, and two sets of rotating rods 32 are fixedly connected to the surface of the gear disk 31. The two ends of the rotating rods 32 are movably fitted with a head limiting seat 33 and a tail limiting seat 331 for limiting.

[0036] A moving rod 34 is fixedly connected to the end of the rotating rod 32 away from the gear disk 31. A positioning slot 35 is integrally formed on the body of the moving rod 34. The positioning slot 35 has a U-shaped design and holds a connecting shaft 36 inside. A lifting rod 37 is fixedly connected above the connecting shaft 36. A scale 38 is provided on the surface of the lifting rod 37. The lifting rod 37 is slidably installed inside the insert rod 39. A moving groove 310 for the movement of the positioning slot 35 is provided on the side of the insert rod 39. The operating component 2 is connected to the gear disk 31, ensuring stable rotation of the rotating rod 32.

[0037] A moving rod 34 is fixedly connected to the end of the rotating rod 32 away from the gear disk 31. A positioning bayonet 35 is integrally formed on the rod body of the moving rod 34. The positioning bayonet 35 has a U-shaped bayonet design. The internal part of the positioning bayonet 35 holds the connecting shaft 36. A lifting rod 37 is fixedly connected above the connecting shaft 36.

[0038] In a specific implementation scheme, when the gear disk 31 rotates, the rotating rod 32, which passes through its surface, rotates accordingly. The moving rod 34, connected to the end of the rotating rod 32 away from the gear disk 31, also rotates. The positioning slot 35 at the top of the moving rod 34 is U-shaped, and its interior holds the connecting shaft 36 at the bottom of the lifting rod 37. When the moving rod 34 rotates, it drives the lifting rod 37 to move up and down inside the insertion rod 39 through the connecting shaft 36. The moving groove 310 on the side of the insertion rod 39 provides space for the movement of the positioning slot 35.

[0039] The lifting rod 37 has a dial 38 on its surface. The lifting rod 37 is slidably installed inside the insert rod 39. The side of the insert rod 39 has a moving groove 310 for the movement of the positioning latch 35. The operating component 2 is connected to the gear disk 31. The lifting rod 37 is a three-dimensional rectangular shape and is fitted into the internal through hole of the insert rod 39. The moving groove 310 on the side of the insert rod 39 extends vertically. The length of the moving groove 310 is greater than the maximum lifting stroke of the lifting rod 37. The U-shaped opening of the positioning latch 35 is engaged with the surface of the connecting shaft 36 and can slide up and down along the moving groove 310.

[0040] In a further embodiment, the scale 38 on the surface of the lifting rod 37 displays the distance it has moved during its vertical movement. Once the device is positioned below the vehicle 9, the lifting rod 37 is raised using the operating handle 22 until its top touches the vehicle chassis. At this point, the scale value on the scale 38 represents the height of the vehicle chassis from the ground, thus completing the detection of the vehicle chassis height.

[0041] The operating component 2 is fixedly mounted on the fixed chassis 4, and a first set of universal wheels 5 for movement is mounted on the bottom of the fixed chassis 4. The bottom ends of the head limit seat 33 and the tail limit seat 331 are respectively fixedly connected to the connecting base plate 6 and the supporting base plate 7. Both the connecting base plate 6 and the supporting base plate 7 are fixedly connected to the side of the fixed chassis 4, and a second set of universal wheels 8 is mounted on the bottom of the insertion rod 39.

[0042] It should be further noted that the first swivel wheel assembly 5 and the second swivel wheel assembly 8 are kept on the same horizontal plane, and the first swivel wheel assembly 5 and the second swivel wheel assembly 8 are moved under the vehicle 9 to detect the chassis height.

[0043] More specifically, in the main body 1 of the detection device, the operating component 2 is fixedly mounted on the fixed chassis 4. The first universal wheel assembly 5 below the fixed chassis 4 and the second universal wheel assembly 8 at the bottom of the insertion rod 39 are kept on the same horizontal plane. When the device is pushed, the first universal wheel assembly 5 and the second universal wheel assembly 8 can rotate flexibly, allowing the entire device to move under the vehicle 9 to prepare for chassis height detection.

[0044] The working principle of this utility model:

[0045] 1. Principle of overall device movement

[0046] The operating component 2 in the main body 1 of the detection device is fixedly mounted on the fixed chassis 4. The first universal wheel assembly 5 under the fixed chassis 4 and the second universal wheel assembly 8 at the bottom of the insertion rod 39 are kept on the same horizontal plane. When the device is pushed, the first universal wheel assembly 5 and the second universal wheel assembly 8 can rotate flexibly, allowing the entire device to move under the vehicle 9 to prepare for chassis height detection.

[0047] 2. Working principle of the operating components

[0048] The handle 22 of the operating component 2 is L-shaped, and its inflection point is hinged to the fixed base plate 21 via the first pin 23. When the handle 22 is moved up or down, the top of the handle 22 drives the receiving rod 24 to move via the second pin 25. The other end of the receiving rod 24 pushes the push rod 26 to slide back and forth within the positioning sleeve 28 via the third pin 27. The toothed plate 29 at the top of the push rod 26 moves accordingly, and the teeth 210 on the bottom surface of the toothed plate 29 mesh with the gear disk 31, thereby driving the gear disk 31 to rotate.

[0049] 3. Working principle of the detection component

[0050] When the gear disk 31 rotates, the rotating rod 32, which passes through its surface, rotates accordingly. Both ends of the rotating rod 32 are limited by a head limit seat 33 and a tail limit seat 331, respectively, ensuring stable rotation. The moving rod 34, connected to the end of the rotating rod 32 away from the gear disk 31, also rotates. The positioning slot 35 at the top of the moving rod 34 is U-shaped, and its interior holds the connecting shaft 36 at the bottom of the lifting rod 37. When the moving rod 34 rotates, it drives the lifting rod 37 to move up and down inside the insertion rod 39 via the connecting shaft 36. The moving groove 310 on the side of the insertion rod 39 provides space for the movement of the positioning slot 35.

[0051] 4. Height Detection Principle

[0052] As the lifting rod 37 moves up and down, the scale 38 on its surface displays the distance it has moved. Once the device is positioned below the vehicle 9, the lifting rod 37 is raised using the operating handle 22 until its top touches the vehicle chassis. At this point, the scale value on the dial 38 indicates the height of the vehicle chassis from the ground, thus completing the detection of the vehicle chassis height.

[0053] In summary, by using a mechanical linkage structure between the operation and detection components, the traditional manual measurement with a measuring tape is replaced, avoiding measurement errors caused by subjective factors in manual operation, significantly improving the accuracy of the detection results. Moreover, the structural design is simple, requiring no complex big data system support, thus reducing development and maintenance costs.

[0054] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
