[0048] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the present disclosure, its application, or use. The present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present disclosure thorough and complete and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that unless otherwise specifically stated, the relative arrangement of parts and steps, the composition of materials, numerical expressions, and numerical values set forth in these embodiments should be interpreted as being merely exemplary and not as limiting.

[0049] The terms "first", "second" and similar terms used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different parts. The terms "include" or "comprises" and similar terms mean that the elements before the term include the elements listed after the term, and do not exclude the possibility of also including other elements. The terms "upper", "lower", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0050] In the present disclosure, when a specific device is described as being located between a first device and a second device, an intervening device may or may not be present between the specific device and the first device or the second device. When a specific device is described as being connected to another device, the specific device may be directly connected to the other device without an intervening device, or may be not directly connected to the other device but with an intervening device.

[0051] All terms (including technical or scientific terms) used in this disclosure have the same meaning as those understood by one of ordinary skill in the art to which this disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in, for example, general dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or highly formal sense, unless explicitly defined herein.

[0052] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0053] In the field of highway maintenance, pavement maintenance is highly mechanized with a full range of mechanical equipment, but maintenance operations in other areas outside the pavement are less mechanized and still mainly rely on manual labor.

[0054] The side ditches and slopes on both sides of the highway have complex terrain, narrow walking space, steep slopes, large environmental differences in different sections of the road, and various ditch widths and sizes. There is no dedicated mechanical equipment in the relevant technology, and manual cleaning is still the main method of maintenance. This is not only inefficient, labor-intensive, and high-maintenance, but also poses a major safety hazard.

[0055] Some related technologies use excavators and other operating equipment to enter the ditch area through a temporary road next to the highway. During the entry process, the excavator's direction of travel needs to change from perpendicular to the ditch to parallel to the ditch. When turning, the excavator's tracks rub against the ground and damage the ditch.

[0056] Side ditch scenarios are complex and varied. In some sections, the diversion troughs on the side slopes directly connect to the side ditch, making it impossible for excavators to cross them while moving, resulting in damage. Side ditch cross-sections can vary, including inverted trapezoidal, rectangular, and triangular shapes. Equipment typically needs to straddle the side ditch to operate, but the space available for movement on either side is narrow, and the ditch width varies. The track gauge between the left and right walking mechanisms of the excavator cannot be adjusted, resulting in poor adaptability to these scenarios.

[0057] In view of this, in one aspect of an embodiment of the present disclosure, a chassis system and an engineering vehicle are provided, which have greater flexibility.

[0058] Figure 1 is a schematic diagram of a working scenario according to some embodiments of the chassis system disclosed herein. Figure 1 Area A is the side ditch, area B is the diversion trough, area C is the working surface when the chassis system is operating, and area D is the highway surface.

[0059] Ditch A is a longitudinal artificial ditch installed outside the roadbed. It collects surface water from the highway surface D and directs it into a smooth drainage channel, discharging it below the road through bridges and culverts. The area between ditch A and the highway surface D is the side slope E, on which a raised diversion channel B can be installed.

[0060] Figure 2 is a schematic structural diagram of some embodiments of the chassis system according to the present disclosure, Figure 3 is a partial schematic diagram of some embodiments of the chassis system according to the present disclosure, Figure 4 Schematic diagram of the connection relationship of some embodiments of the chassis system according to the present disclosure.

[0061] refer to Figures 1 to 4 The chassis system includes a frame 1, a posture adjustment mechanism 2, a steering mechanism 3, a walking mechanism 4 and a processor 5. One end of the posture adjustment mechanism 2 is hinged to the frame 1, and the posture adjustment mechanism 2 is configured to rotate around a first direction X relative to the frame 1.

[0062] The steering mechanism 3 includes a mounting body 31 and a rotating body 32 hinged to the mounting body 31 . The mounting body 31 is connected to the other end of the posture adjustment mechanism 2 . The rotating body 32 is configured to rotate relative to the mounting body 31 around a second direction Y perpendicular to the first direction X.

[0063] The walking mechanism 4 is connected to the rotating body 32 , and the processor 5 is signal-connected to the posture adjustment mechanism 2 and the steering mechanism 3 , and is configured to enable at least one of the posture adjustment mechanism 2 and the steering mechanism 3 to adjust the posture of the walking mechanism 4 .

[0064] The first direction X includes but is not limited to the length direction of the frame 1, the second direction Y includes but is not limited to the height direction of the frame 1 or perpendicular to the horizontal plane, and the third direction Z includes but is not limited to the length direction of the frame 1 and the initial travel direction of the walking mechanism 4.

[0065] The posture adjustment mechanism 2 includes but is not limited to being arranged on the side of the frame 1. The hinge axis of the posture adjustment mechanism 2 and the frame 1 is parallel to the first direction X. The posture adjustment mechanism 2 drives the walking mechanism 4 to rotate around the first direction X, thereby realizing the raising or lowering of the walking mechanism 4 relative to the frame 1.

[0066] The steering mechanism 3 is connected between the attitude adjustment mechanism 2 and the traveling mechanism 4. The axis of the articulation between the rotating body 32 and the mounting body 31 is parallel to the second direction Y. The steering mechanism 3 drives the traveling mechanism 4 to rotate about the second direction Y, enabling the traveling mechanism 4 to achieve horizontal steering. This allows the chassis system's travel direction to be switched according to operating conditions during operation, for example, achieving 90° lateral movement. The attitude adjustment mechanism 2 includes, but is not limited to, an articulated connection with the mounting body 31, allowing it to rotate relative to the mounting body 31, achieving greater freedom of adjustment.

[0067] By raising and lowering the running gear 4, the chassis system can cross obstacles such as the diversion trough B during operation. After the running gear 4 is raised to clear the working surface C, the steering mechanism 3 drives the running gear 4 to turn horizontally, and then the running gear 4 is lowered to the working surface C. The running gear 4 does not come into contact with the working surface C during the turning process, and will not damage the side ditch.

[0068] By rotating the traveling mechanisms 4 about the first direction X, the distances between the multiple traveling mechanisms 4 change, thereby adjusting the wheelbase of the chassis system and enabling the chassis system to adapt to side gutters A of different sizes.

[0069] In this embodiment, the posture of the walking mechanism 4 is adjusted by at least one of the posture adjustment mechanism 2 and the steering mechanism 3, so that the chassis system can realize multiple functions such as obstacle crossing, on-the-spot steering, lateral walking and track gauge adjustment, and can flexibly meet complex and diverse working scenarios such as ditch A and slope E, and has strong flexibility and adaptability.

[0070] refer to Figures 1 to 4In some embodiments, the walking mechanism 4 is configured to travel on the working surface C. The processor 5 is configured to rotate the posture adjustment mechanism 2 to drive the walking mechanism 4 to leave the working surface C, and then rotate the steering mechanism 3 to drive the walking mechanism 4 to turn, thereby adjusting the travel direction of the walking mechanism 4.

[0071] In this embodiment, by lifting the walking mechanism 4 off the working surface C and then adjusting the traveling direction of the walking mechanism 4, it is possible to avoid wear of the working surface C during the turning process of the walking mechanism 4. It is also possible to reduce the risk of damage caused by collision with the ditch A, guide groove B and / or slope E during the turning process due to the narrow working area, thereby helping to improve the reliability and flexibility of the chassis system posture adjustment.

[0072] refer to Figures 1 to 4 In some embodiments, the number of the posture adjustment mechanism 2, the steering mechanism 3, and the traveling mechanism 4 are multiple and are spaced apart along the periphery of the frame 1. The processor 5 is configured to adjust the travel directions of the multiple traveling mechanisms 4 in sequence.

[0073] The number of the posture adjustment mechanism 2, the steering mechanism 3, and the traveling mechanism 4 includes, but is not limited to, four each, with one posture adjustment mechanism 2, one steering mechanism 3, and one traveling mechanism 4 forming a group. Two groups are provided on each side of the frame 1 along the first direction X, and the two groups on the same side are spaced apart along the third direction Z.

[0074] During the steering process, one traveling mechanism 4 is first lifted off the working surface C, and the other three traveling mechanisms 4 form a three-point support on the working surface C to improve the stability of the steering process. The four traveling mechanisms 4 complete the steering operation in sequence.

[0075] During the obstacle traversal process, the two front running mechanisms 4 relative to the travel direction are first lifted off the working surface C. The two rear running mechanisms 4 then support themselves on the working surface C and continue to travel forward. The two front running mechanisms 4, which have been lifted off, are then lowered, and the two rear running mechanisms 4 relative to the travel direction are lifted off the working surface C. The two front running mechanisms 4 then support themselves on the working surface C and continue to travel forward. After the two rear running mechanisms 4 have cleared the obstacle, the two rear running mechanisms 4 are lowered. The front and rear running mechanisms 4 sequentially traverse the obstacle, improving the stability of the obstacle traversal operation.

[0076] In this embodiment, steering is achieved by making the multiple traveling mechanisms 4 leave the working surface C in sequence, so that the posture of the chassis system can be kept stable during steering and obstacle crossing, thereby reducing the risk of overturning.

[0077] refer to Figure 4In some embodiments, the chassis system further includes a detection mechanism 6. Detection mechanism 6 is configured to obtain posture information of the frame 1, the posture adjustment mechanism 2, and the steering mechanism 3. The processor 5 is signal-connected to the detection mechanism 6 and is configured to determine the posture of the chassis system based on the posture information of the frame 1, the posture adjustment mechanism 2, and the steering mechanism, so that a user can accurately monitor the posture of the chassis system.

[0078] When traveling on slope E, the detection mechanism 6 detects the angle data of the frame 1 and the attitude adjustment mechanism 2 and sends it to the processor 5. The processor 5 calculates the current attitude of the chassis system and the center of gravity position of the entire vehicle, and then controls the attitudes of the four attitude adjustment mechanisms 2 to keep the entire vehicle in a stable attitude at all times, avoiding the risk of rollover.

[0079] In this embodiment, the processor 5 causes the attitude adjustment mechanism 2 and the steering mechanism 3 to perform corresponding actions according to user instructions to adjust the chassis system to a specified attitude. The processor 5 can integrate functions such as one-touch leveling, one-touch reset, and active anti-rollover to improve user convenience.

[0080] refer to Figures 1 to 3 In some embodiments, the walking mechanism 4 includes a power assembly 41 and a walking portion 42 connected to an output end of the power assembly 41. The walking portion 42 includes tracks or tires.

[0081] In this embodiment, the running part 42 may be a track or a tire. Tracks include, but are not limited to, triangular tracks. Triangular tracks have a large contact area with the working surface C, exerting little pressure on the working surface, and effectively protecting the side ditch A from damage. When the running part 42 is a tire, the posture adjustment mechanism 2 is preferably a swing arm. When the swing arm swings, the tire at the end of the swing arm can flexibly follow the movement.

[0082] refer to Figures 1 to 3 In some embodiments, the posture adjustment mechanism 2 includes a plurality of swing arms arranged in parallel and spaced apart along the second direction, each swing arm being respectively connected to the frame and the mounting body 31. When the posture adjustment mechanism 2 includes a plurality of swing arms, the walking portion 42 is preferably a crawler.

[0083] In this embodiment, the number of swing arms includes but is not limited to two. The two swing arms form a parallelogram, which can drive the walking mechanism 4 to move horizontally so that the walking mechanism 4 can always be parallel to the working surface C during the posture adjustment process, thereby achieving more stable driving.

[0084] refer to Figure 2 In some embodiments, a hollow receiving space 311 is defined between the mounting body 31 and the rotating body 32, and the power assembly 41 is disposed in the receiving space 311. Both the mounting body 31 and the rotating body 32 may include arcuate surfaces to enclose the receiving space 311.

[0085] One end of the oil cylinder 33 is connected to the rotating body 32, and the other end is connected to the mounting body 31, and is arranged outside the accommodation space 311. The power assembly 41 includes a drive motor and a reducer. One end of the reducer is fixed to the side of the rotating body 32 by bolts, and the other end is fixed to the walking part 42.

[0086] In this embodiment, the accommodating space 311 can accommodate the drive motor, reducing the size and occupied space of the steering mechanism 3, making the chassis system layout more compact, so as to operate more flexibly in a narrow working environment.

[0087] refer to Figure 1 In some embodiments, the surface of the frame 1 has one or more hinged parts, and the chassis system is configured to be connected to the machine 9 or the vehicle through the hinged parts. The vehicle can be configured in different forms according to actual functional requirements.

[0088] The first hinge 11 is located at the top of the frame 1 along the second direction Y. The first hinge 11 is used to be hinged to the vehicle. The second hinge 12 is located at the front or rear side of the frame 1 along the third direction Z. The second hinge 12 is used to connect to the tool 9.

[0089] By combining different vehicles and selecting different operating tools, the chassis system can be combined with different vehicles and operating tools to form a variety of mechanical equipment, realize multiple operating functions, and meet the needs of more scenarios.

[0090] Figure 5A 、 5B 5C are schematic diagrams of working states of some embodiments of the engineering machinery disclosed herein, Figure 6A 、 6B 6C are schematic diagrams of the steering process according to some embodiments of the engineering machinery of the present disclosure.

[0091] refer to Figures 5A-5C and Figures 6A-6C In another aspect of the embodiments of the present disclosure, an engineering vehicle is provided, comprising: a chassis system, a slewing mechanism 7 and an arm 8 as in any of the above embodiments.

[0092] The traveling mechanism 4 is configured to travel on the working surface C. The slewing mechanism 7 is disposed on the top of the frame 1 and is configured to rotate relative to the frame 1 in a second direction Y. The boom 8 is connected to the slewing mechanism 7. The processor 5 is connected to the boom 8 and is configured to support the end of the boom 8 on the working surface when the traveling mechanism 4 is driven to lift off the working surface.

[0093] When a construction vehicle crosses an obstacle such as a ditch A or trench B, the boom 8 can provide auxiliary support for the construction vehicle when the traveling mechanism 4 leaves the working surface C. For example, when a construction vehicle enters a ditch, it is usually necessary to switch from traveling perpendicular to the ditch to traveling across the ditch, parallel to the length of the ditch.

[0094] The boom 8 is supported on the working surface C, and the construction vehicle moves forward, thereby assisting the traveling mechanism 4, which is located at the front relative to the direction of travel, to cross the ditch and reach the other side of the ditch, allowing the construction vehicle to straddle the ditch. The auxiliary support of the boom 8 can reduce the risk of the construction vehicle tipping over when the traveling mechanism 4 crosses the ditch and becomes airborne.

[0095] In this embodiment, the chassis of the engineering vehicle can adjust its posture and turn 90 degrees, and can realize functions such as obstacle crossing, on-the-spot turning, lateral walking and adjustable track gauge, meeting the walking needs in complex scenes such as ditches and slopes, and has strong flexibility.

[0096] refer to Figures 5A-5B and Figures 6A-6C In some embodiments, the engineering vehicle further includes an implement 9 connected to the end of the boom 8 or the frame 1. The implement 9 includes at least one of a bucket and a mowing head.

[0097] The tool 9 can be selected according to the actual application scenario. When the tool 9 uses a bucket or a mowing head, the engineering vehicle is Figures 5A-5B The side ditch cleaning vehicle shown in FIG. The tool 9 is contained in the end of the arm support 8 and can be quickly switched by a fully automatic quick-change device.

[0098] In this embodiment, the engineering vehicle can be used in ditch and slope cleaning scenarios to flexibly and stably clean the soil deposited in the ditch and trim the weeds and trees on the slope without damaging the ditch.

[0099] refer to Figure 5C In some embodiments, the engineering vehicle further includes a tool 9 connected to the end of the boom 8 or the frame 1. The tool 9 includes at least one of a milling machine, a sweeper, a flat shovel, and a plate compactor, and the milling machine is hinged to the frame 1.

[0100] When the tool 9 is a milling machine, a sweeper, a flat shovel or a plate compactor, the engineering vehicle is a road pothole repair vehicle. The milling machine is arranged on the front side of the frame 1 through the second hinge portion 12 and can swing around the hinge point to achieve height adjustment.

[0101] In this embodiment, the engineering vehicle can also be used as a road pothole repair vehicle to repair road defects, achieving multiple operational functions, and the application scenarios of the engineering vehicle are diverse. The chassis system can also be combined with different upper vehicles to form a variety of mechanical equipment.

[0102] refer to Figures 6A-6C , the operation process of switching the engineering vehicle from the normal travel mode to the lateral travel mode in the ditch scene is given:

[0103] In step 1, the boom 8 supports the ground, the whole vehicle moves forward, and the boom 8 is retracted at the same time, and finally the two front walking mechanisms 4 pass over the ditch A. At this time, the engineering vehicle straddles the ditch A.

[0104] like Figure 6A In step 2, the posture adjustment mechanism 2 is swung upward, driving one of the walking mechanisms 4 to move off the ground. At this time, the engineering vehicle still has three support points to ensure stability, and the arm 8 can also be used to support the ground to further improve the stability of the vehicle.

[0105] like Figure 6B In step three, the oil cylinder 33 of the steering mechanism 3 retracts, causing the rotating body 32 to drive the traveling mechanism 4 to rotate 90° together.

[0106] like Figure 6C In step 4, the posture adjustment mechanism 2 swings downward, and the walking mechanism 4 falls back and supports the ground.

[0107] Repeat steps 2 to 4 to complete the 90° rotation of all four traveling mechanisms 4. At this time, the vehicle is adjusted to the lateral movement mode. When the traveling mechanism 104 rotates 90°, it does not contact the ground and will not damage the side ditch.

[0108] When an engineering vehicle is traveling on ditch A and needs to cross diversion trough B, the operation process is similar to switching to travel mode:

[0109] The posture adjustment mechanism 2 is swung upward, so that the front running mechanism 4 is lifted off the ground and exceeds the height of the guide groove B. The engineering vehicle moves forward until the front running mechanism 4 completely passes over the guide groove B;

[0110] The posture adjustment mechanism 2 swings downward, causing the front traveling mechanism 4 to fall back to the supporting ground, and the rear traveling mechanism 4 to be lifted off the ground and exceed the height of the guide groove B. The engineering vehicle moves forward until the rear traveling mechanism 4 completely passes over the guide groove B.

[0111] The posture adjustment mechanism 2 is swung downward until the traveling mechanism 4 at the rear side also supports the ground, and the entire vehicle completely passes over the guide groove B.

[0112] When the engineering vehicle is in the normal driving mode, the posture adjustment mechanism 2 is generally parallel to the vehicle's driving direction. When the posture adjustment mechanism 2 swings, the wheelbase between the front and rear traveling mechanisms 4 changes; when the engineering vehicle is in the lateral movement mode, the posture adjustment mechanism 2 is perpendicular to the vehicle's driving direction. When the posture adjustment mechanism 2 swings, the track gauge between the left and right traveling mechanisms 4 changes, so that it can adapt to ditches of various widths.

Based on the above description, those skilled in the art can fully understand how to implement the technical solutions disclosed herein.
