[0003] Furthermore, during extended periods of operation, operators lack suitable rest and operating positions. Traditional chassis have not been effectively designed to address this issue, resulting in poor ease and comfort of operation. Therefore, existing vehicle chassis technology struggles to meet complex working conditions and diverse needs. Utility Model Content

[0032] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0033] The purpose of this utility model is to provide a multi-functional remote control vehicle chassis and a remote control moving vehicle to solve the problems existing in the prior art. It has a simple structure, can provide complex motion functions, effectively meet the needs of working conditions, and improve the convenience and comfort of operators during the operation process.

[0034] To make the above-mentioned objectives, features and advantages of the utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] This embodiment provides a multi-functional remote-controlled car chassis, such as Figures 1-4As shown, the system includes: a vehicle body 11, an omnidirectional travel mechanism 12, multiple suspension mechanisms 13, and a remote controller. A driver's seat is provided at the front end of the top of the vehicle body 11 for the operator to sit in. A support station is provided at the rear end of the top of the vehicle body 11 for installing a support mechanism 2 to support the aircraft fuselage 3 that needs to be moved. The omnidirectional travel mechanism 12 is installed below the vehicle body 11 to enable the vehicle body 11 to move in all directions. Multiple suspension mechanisms 13 are installed between the vehicle body 11 and the omnidirectional travel mechanism 12 to raise or lower the vehicle body 11 and absorb the impact force transmitted from the omnidirectional travel mechanism 12 to the vehicle body 11. The remote controller is signal-connected to the omnidirectional travel mechanism 12 and the suspension mechanisms 13.

[0037] The driver's bay provides an operating area for the operator, ensuring convenience and comfort, and allowing the operator to stably control the vehicle. The support bay provides a dedicated support installation position for transporting large, irregular equipment such as aircraft fuselages 3, laying the foundation for specific transport functions and expanding the application range of chassis 1, enabling it to be used in special fields such as aviation equipment transport. The omnidirectional travel mechanism 12, located below the vehicle body 11, ensures its effective function, driving the vehicle body 11 to move in all directions. Compared to traditional travel mechanisms, this omnidirectional movement capability greatly enhances the vehicle's maneuverability and flexibility in complex spatial environments. For example, in narrow, crowded, or irregularly shaped spaces, the vehicle can move and rotate directly in all directions without turning, significantly improving the vehicle's passage efficiency and operational accuracy, and adapting to more complex operating scenarios. The suspension mechanism 13, located between the vehicle body 11 and the omnidirectional travel mechanism 12, enables both the lifting and lowering of the vehicle body 11 and effective shock absorption. In different operating scenarios, the height of the vehicle body 11 can be adjusted according to actual needs. For example, when encountering uneven roads or special loading / unloading requirements, the vehicle body 11 can be flexibly raised or lowered to improve passability and adaptability. Simultaneously, the shock absorption function effectively reduces the impact of road bumps and the shocks generated during driving on the vehicle body 11, protecting the equipment and components inside the vehicle, extending their service life, and improving the overall stability and driving comfort of the vehicle. The remote control is connected to the omnidirectional travel mechanism 12 and the suspension mechanism 13, constructing a convenient and precise control system. Operators can accurately control the movement direction, speed, and other parameters of the omnidirectional travel mechanism 12 through signals sent by the remote control, achieving flexible omnidirectional movement of the vehicle body 11; at the same time, they can precisely control the lifting and lowering actions of the suspension mechanism 13, adjusting the height of the vehicle body 11 according to actual conditions. This efficient signal connection ensures the coordinated operation of all key components of the vehicle, improving overall handling performance and operational accuracy.

[0038] In a preferred embodiment, the multi-functional remote-controlled vehicle chassis 1 further includes a folding seat cushion 14 and a folding pedal 15. The folding seat cushion 14 is located at one end of the top surface of the vehicle body 11, and the folding pedal 15 is installed at the front end of the vehicle body 11. The folding seat cushion 14 and the folding pedal 15 form a driving position. The design of the folding seat cushion 14 and the folding pedal 15 not only meets the operator's seating needs when resting but also takes into account the compactness and maneuverability of the overall vehicle structure. When the seat and pedal functions are not needed, they can be folded away, not occupying too much space and reducing the overall height and volume of the vehicle, so as not to be affected when passing through some space-constrained areas (such as low warehouses or narrow passages). When long-term operation is required, the seat cushion and pedal can be unfolded to provide comfortable support for the operator, improving the operating experience and efficiency.

[0039] In a preferred embodiment, the omnidirectional driving mechanism 12 includes a power system 121 and multiple Mecanum omnidirectional wheels 122. The multiple Mecanum omnidirectional wheels 122 are symmetrically mounted on both sides of the vehicle body 11. The fixed end of the power system 121 is fixedly connected to the vehicle body 11, and the output end of the power system 121 is drive-connected to the Mecanum omnidirectional wheels 122. The power system 121 is also connected to a remote control signal. By using the Mecanum omnidirectional wheels 122 as driving components, combined with the compatible power system 121, the chassis 1 can achieve flexible omnidirectional movement. The symmetrical mounting ensures the balance and stability of the vehicle during omnidirectional movement. The fixed connection between the power system 121 and the vehicle body 11 ensures reliable power transmission, and the drive-connection with the Mecanum omnidirectional wheels 122 provides stable power support for omnidirectional driving. The signal connection with the remote control enables precise control of the driving function, allowing the operator to easily control the vehicle to drive in different directions and at different speeds as needed.

[0040] In a preferred embodiment, the power system 121 includes a motor and a reducer. The fixed end of the motor is fixedly connected to the vehicle body 11, and the output end of the motor is connected to the Mecanum omnidirectional wheel 122 via the reducer. The power system 121, consisting of the motor and reducer, has a reasonable and efficient structure. The motor provides the power source and is fixedly connected to the vehicle body 11, ensuring the stability of the power source. The reducer allows for adjustment of the speed and torque according to actual needs, precisely matching the operating requirements of the Mecanum omnidirectional wheel 122, and meeting the power and speed requirements of the vehicle in different operating scenarios. For example, when rapid movement is required, the speed can be increased, while when carrying heavy objects or requiring greater torque, the torque can be adjusted via the reducer, ensuring the stability and flexibility of vehicle operation.

[0041] In a preferred embodiment, four Mecanum omnidirectional wheels 122 are used, and a suspension mechanism 13 is installed between each Mecanum omnidirectional wheel 122 and the vehicle body 11. This arrangement of four Mecanum omnidirectional wheels 122 provides stable support and a foundation for omnidirectional driving performance. Each omnidirectional wheel is equipped with a suspension mechanism 13 between itself and the vehicle body 11, ensuring good contact between the four Mecanum omnidirectional wheels 122 and the ground under different road conditions, thus improving vehicle stability and grip. Furthermore, the arrangement of one suspension mechanism 13 corresponding to one Mecanum omnidirectional wheel 122 also facilitates precise adjustment of the vehicle body 11's height, enabling accurate adjustment of the vehicle body 11's horizontal posture and adapting to various complex terrains and handling operation requirements.

[0042] In a preferred embodiment, the suspension mechanism 13 includes a swing arm, a shock absorber, and a hydraulic cylinder 131. The top end of the swing arm is rotatably connected to the vehicle body 11, and a Mecanum omnidirectional wheel 122 is mounted on the bottom end of the swing arm. One end of the shock absorber is rotatably connected to the vehicle body 11, and the other end is hinged to the bottom end of the swing arm. The fixed end of the hydraulic cylinder 131 is hinged to the vehicle body 11, and the lifting end of the hydraulic cylinder 131 is hinged to the middle of the shock absorber. The hydraulic cylinder 131 is connected to a remote control signal. The remote control controls the lifting of the hydraulic cylinder 131, which drives the shock absorber to rotate, thereby driving the swing arm to rotate and causing the vehicle body 11 to rise or fall. This structural design of the suspension mechanism 13 enables precise lifting control and effective shock absorption. The hydraulic cylinder 131 achieves lifting action through the remote control signal, drives the shock absorber to rotate, and then drives the swing arm to swing, ultimately achieving height adjustment of the vehicle body 11. This transmission method can precisely control the rise or fall of the vehicle body 11, meeting the precise height adjustment requirements of the vehicle body 11 in different operating scenarios. At the same time, the shock absorption mechanism plays a role throughout the process, effectively absorbing the impact force generated by road bumps and ensuring the stability of the vehicle body 11 during operation.

[0043] In a preferred embodiment, the shock absorption mechanism includes a shock absorber spring, a damper, and a connecting plate. One end of the damper is fixedly connected to the connecting plate, and the other end is hinged to the swing arm. The shock absorber spring is sleeved on the outside of the damper, and both ends of the spring are fixedly connected to the ends of the damper. The end of the connecting plate away from the damper is rotatably connected to the front of the vehicle, and the middle part of the connecting plate is hinged to the lifting end of the hydraulic cylinder 131. This shock absorption mechanism design, in which the shock absorber spring and damper work together, can more effectively absorb and buffer the impact force during vehicle operation. The shock absorber spring is responsible for absorbing most of the impact force, storing energy through its elastic deformation to reduce the magnitude of the impact force transmitted to the vehicle body 11. The damper controls the extension and retraction speed of the shock absorber spring, preventing excessive back-and-forth oscillation and making the shock absorption process smoother and more efficient. The connecting plate not only connects the various components but also is properly hinged to the vehicle body 11 and the hydraulic cylinder 131, ensuring reliable force transmission and the stability of the entire shock absorption mechanism, further improving the vehicle's driving comfort and the protection effect of the vehicle body 11.

[0044] In a preferred embodiment, the damper is a hydraulic damper, which possesses excellent damping characteristics and adjustability. Compared to other types of dampers, the hydraulic damper can more precisely adjust the damping force according to different road conditions and impact magnitudes during vehicle operation. When facing large impacts, the hydraulic damper can provide a larger damping force, quickly suppressing the deformation of the shock absorber springs and reducing vehicle body vibration; when the impact force is small, the damping force can be appropriately reduced, allowing the shock absorber springs to extend and retract more naturally, resulting in a smoother vehicle ride. This characteristic effectively enhances the adaptive capability of the vehicle's shock absorption system, enabling it to adapt to a wider range of road conditions.

[0045] In a preferred embodiment, the remote control is a portable remote control. Choosing a portable remote control significantly improves the operator's ease and flexibility in controlling the vehicle. The operator can move freely within a certain range, standing in the most suitable position to observe the work scene and perform operations, and controlling the vehicle in all directions without being limited to a fixed driving position. This convenience is particularly suitable for work environments with limited operating space or requiring flexible adjustment of the operating position, reducing the complexity of operations and enabling more efficient completion of various handling tasks.

[0046] Example 2

[0047] This embodiment also provides a remote-controlled moving vehicle, such as Figures 5-9As shown, the multi-functional remote-controlled car chassis 1 and support mechanism 2, as described in any of the above embodiments, are included. The support mechanism 2 includes a base 21, a lifting mechanism 22, a horizontal rotation mechanism 23, an elastic buffer mechanism 24, a fixed support plate 25, a first flip support plate 26, a second flip support plate 27, a first telescopic mechanism 28, and a second telescopic mechanism 29. The base 21 is used for mounting on the support position; the fixed end of the lifting mechanism 22 is mounted on the top surface of the base 21; the fixed end of the horizontal rotation mechanism 23 is mounted on the lifting end of the lifting mechanism 22; the elastic buffer mechanism 24 is mounted on the rotating end of the top of the horizontal rotation mechanism 23; the fixed support plate 25 is mounted on the top of the elastic buffer mechanism 24; and the first flip support plate 26 and the fixed support plate 25 are connected together. The system features a side-hinged connection; the second tilting support plate 27 is hinged to the side of the fixed support plate 25 away from the first tilting support plate 26; one end of the first telescopic mechanism 28 is hinged to the bottom of the fixed support plate 25, and the other end is hinged to the first tilting support plate 26; one end of the second telescopic mechanism 29 is hinged to the fixed support plate 25, and the other end is hinged to the second tilting support plate 27. The extension and retraction of the first telescopic mechanism 28 can cause the first tilting support plate 26 to tilt, and the extension and retraction of the second telescopic mechanism 29 can cause the second tilting support plate 27 to tilt, thereby enabling the top surfaces of the first tilting support plate 26, the second tilting support plate 27, and the fixed support plate 25 to form a support surface that matches the aircraft to be moved. Applying the multi-functional remote-controlled vehicle chassis 1 to the remote-controlled transport vehicle allows the remote-controlled transport vehicle to inherit all the advantages of chassis 1. The omnidirectional driving function enables the remote-controlled transport vehicle to flexibly move to designated positions in various work areas and accurately dock with the objects to be transported. The height-adjustable suspension mechanism 13 can adjust the overall vehicle height according to the height of the handling equipment and the requirements of the work site, facilitating loading, unloading, and transportation. Excellent shock absorption ensures that both the handling equipment and the vehicle structure are well protected during handling, reducing the risk of damage caused by road bumps. Meanwhile, the driver's seat, folding seat 14, and pedals enhance the operator's convenience and comfort. This integrated series of functions effectively improves the operational efficiency, safety, and practicality of the remote-controlled moving vehicle, enabling it to better meet the needs of complex handling tasks. By adjusting the first and second telescopic mechanisms 29, the three support plates can form a support surface that conforms to the aircraft's shape, thereby better distributing the aircraft's weight during handling, avoiding excessive local pressure, improving the stability and safety of the support, reducing damage to the aircraft caused by improper support, and broadening the application range of the remote-controlled moving vehicle in various aviation equipment handling scenarios.

[0048] In a preferred embodiment, the lifting mechanism 22 includes a drive motor 221 and four screw jacks 222. The four screw jacks 222 are installed at the four corners of the top surface of the base 21, and the drive motor 221 is installed in the middle of the top surface of the base 21. The output shaft of the drive motor 221 is connected to each screw jack 222 via a transmission assembly to drive the output end of the screw jack 222 to rise or fall. The output end of the screw jack 222 is fixedly connected to the fixed end of the horizontal rotation mechanism 23. This layout of the lifting mechanism 22 enables a smooth and precise lifting function. The four screw jacks 222 are evenly distributed at the four corners of the base 21, working in conjunction with the drive motor 221 in the middle, ensuring that the horizontal rotation mechanism 23 and the supporting structure above it are subjected to uniform force during lifting, effectively preventing tilting and swaying, and ensuring that the vehicle maintains good stability at different heights. Through the transmission components, the drive motor 221 can efficiently transmit power to each screw jack 222, achieving synchronized lifting actions. The height can be precisely adjusted according to different operational needs (such as loading and unloading aircraft at different heights). This stable and precise lifting method improves the adaptability of the remote-controlled moving vehicle to various operational scenarios, thereby enhancing its operational efficiency and safety.

[0049] In a preferred embodiment, the horizontal rotation mechanism 23 is a slewing bearing. The outer ring of the slewing bearing is fixedly connected to the drive end of each screw jack 222, and the inner ring is fixedly connected to the elastic buffer mechanism 24. Using the slewing bearing as the horizontal rotation mechanism 23 provides reliable horizontal rotation capability for the fixed support plate 25 and the structure above it. The slewing bearing features high load-bearing capacity and smooth rotation, ensuring the stability and accuracy of the remote-controlled moving vehicle when adjusting the support surface direction. The connection between the outer ring and the drive end of the screw jack 222, and the inner ring and the elastic buffer mechanism 24, allows the support structure to work together during height adjustment and horizontal rotation. This enables the remote-controlled moving vehicle to easily rotate the support surface horizontally to accommodate aircraft at different placement angles, greatly improving the operational flexibility and applicability of the remote-controlled moving vehicle, reducing handling difficulties and potential equipment damage risks caused by unsuitable support angles, and playing a crucial role, especially in complex work environments.

[0050] In a preferred embodiment, the elastic buffer mechanism 24 includes multiple buffer springs. The bottom end of each buffer spring is fixedly connected to the inner ring of the slewing bearing, and the top end of each buffer spring is fixedly connected to the bottom surface of the fixed support plate 25. The elastic buffer mechanism 24, composed of multiple buffer springs, provides secondary buffering. During vehicle operation and aircraft handling, the buffer springs further absorb road vibrations and impacts generated during aircraft placement and movement. The combined action of multiple buffer springs disperses pressure, ensuring more uniform force transmission between the fixed support plate 25 and the slewing bearing, and preventing excessive local stress. This not only helps protect the fixed support plate 25 and other connecting components but also further enhances the stability of the aircraft support, preventing displacement or damage between the aircraft and the support surface due to excessive vibration and impact, providing additional safety for handling operations, and improving the durability and reliability of the entire remote-controlled moving vehicle system.

[0051] In a preferred embodiment, the system further includes multiple first hinge seats and multiple second hinge seats. The first telescopic mechanism 28 includes multiple second hydraulic cylinders 131. Each first hinge seat is evenly installed on the bottom of one side of the fixed support plate 25. One end of each second hydraulic cylinder 131 is hinged to a first hinge seat, and the other end is hinged to the middle of the first tilting support plate 26. The second telescopic mechanism 29 includes multiple third hydraulic cylinders 131. Each second hinge seat is evenly installed on the bottom of the fixed support plate 25 on the side away from the first tilting support plate 26. One end of each third hydraulic cylinder 131 is hinged to a second hinge seat, and the other end is hinged to the middle of the second tilting support plate 27. This arrangement allows the first and second tilting support plates 27 to achieve smooth and flexible tilting under the precise control of the hydraulic cylinders 131. The multiple hydraulic cylinders 131, in cooperation with the hinge seats, can provide a large driving torque, ensuring the smooth operation of the tilting action. By precisely controlling the extension and retraction of the hydraulic cylinder 131, the first and second tilting support plates 27 can be tilted to a suitable angle to form the optimal support surface shape together with the fixed support plate 25. Simultaneously, the coordinated structural design of multiple components enhances the strength and reliability of the entire support mechanism 2, enabling it to withstand greater pressure and weight, ensuring the stability of the support structure during handling, effectively improving the remote-controlled transfer vehicle's support capability and handling efficiency for aircraft of different shapes, reducing the risk of support structure deformation or failure, and ensuring efficient and safe handling operations.

[0052] In a preferred embodiment, the fixed support plate 25, the first flip support plate 26, and the second flip support plate 27 are curved plates. Using curved plates as the fixed support plate 25, the first flip support plate 26, and the second flip support plate 27 allows for better conformity to the curved surfaces commonly found on most aircraft. Compared to flat plates, curved plates have a tighter contact with the aircraft surface and a larger contact area, allowing the aircraft's weight to be distributed more evenly on the support surface. On one hand, the larger contact area and better fit reduce the pressure per unit area, effectively preventing damage to the aircraft surface due to excessive local pressure; on the other hand, the uniform pressure distribution improves the overall load-bearing capacity of the support mechanism 2, making the support more stable and reliable, reducing swaying caused by unstable support during handling, ensuring the safety and stability of the aircraft during handling, and further enhancing the adaptability and precision of the remote-controlled transfer vehicle for aircraft handling operations.

[0054] This embodiment provides a method for using a remote-controlled moving vehicle as described in Embodiment 2:

[0055] Preparation stage

[0056] Site survey: Operators must first conduct a detailed survey of the work site to understand the spatial layout and ground conditions (such as whether it is flat and whether there are obstacles), and determine the location of large equipment such as the aircraft fuselage 3 to be moved and the target placement point.

[0057] Vehicle deployment and attitude adjustment

[0058] The multi-functional remote-controlled vehicle chassis 1 is moved to a suitable position near the aircraft fuselage 3 that needs to be transported. The omnidirectional driving mechanism 12 is operated using a portable remote control to flexibly adjust the position and direction of the vehicle body 11 according to the space and position of the aircraft fuselage 3. Due to the function of the omnidirectional driving mechanism 12, the vehicle can move horizontally and rotate directly to the designated location without turning in narrow, crowded or irregularly shaped spaces, ensuring that the vehicle accurately aligns with the transport position of the aircraft fuselage 3.

[0059] Based on the height of the aircraft fuselage 3 and the loading and unloading requirements, the hydraulic cylinder 131 of the suspension mechanism 13 is raised and lowered by remote control, which drives the shock absorption mechanism to rotate, and then drives the swing arm to rotate, precisely adjusting the height of the vehicle body 11 to ensure that the relative height between the vehicle and the aircraft fuselage 3 is suitable for subsequent handling operations. At the same time, the shock absorption mechanism can absorb the impact of road bumps to ensure the stability of the vehicle body 11.

[0060] Supporting Institution 2 Preparation

[0061] Install the base 21 on the support position of the vehicle body 11 and confirm that the installation is secure.

[0062] Based on the shape characteristics, placement angle, and support requirements of the aircraft fuselage 3, the drive motor 221 is controlled to drive four screw elevators 222 to rise or fall synchronously through the transmission component, so that the horizontal rotation mechanism 23 and the upper support structure are raised or lowered to a suitable height to adapt to the bottom height of the aircraft fuselage 3 and maintain horizontal stability.

[0063] The horizontal rotation mechanism 23 (slewing bearing) rotates the support structure with fixed support plate 25, first flip support plate 26 and second flip support plate 27 to a suitable direction so that each support plate can accurately correspond to the support part of the aircraft fuselage 3.

[0064] Based on the outline of the aircraft fuselage 3, the first telescopic mechanism 28 (multiple second hydraulic cylinders 131) and the second telescopic mechanism 29 (multiple third hydraulic cylinders 131) are operated. The second and third hydraulic cylinders 131 are controlled by remote control to extend and retract, causing the first and second tilting support plates 27 to tilt to appropriate angles respectively. Together with the fixed support plate 25, they form an arc-shaped support surface that matches the shape of the aircraft fuselage 3, so that the weight of the aircraft fuselage 3 can be more evenly distributed on the support surface, avoiding excessive local pressure.

[0065] Transportation stage

[0066] Connection and Fixing: Reliably connect the support mechanism 2 of the remote-controlled moving vehicle to the aircraft fuselage 3. Appropriate fixing devices (such as straps, buckles, etc., specific devices are not mentioned but need to be considered in actual application) can be used to ensure that the relative positions of the two are fixed during the transportation process and prevent displacement.

[0067] Handling operations

[0068] During transport, operators can adjust the height of the vehicle body 11 using the suspension mechanism 13 via remote control, depending on road conditions. When encountering uneven surfaces, the vehicle body 11 is raised to improve passability; when traveling on smooth surfaces, the height of the vehicle body 11 can be appropriately lowered to improve stability. Simultaneously, the shock absorption mechanism continuously functions to reduce the impact of road bumps on the aircraft fuselage 3 and the vehicle body 11, protecting the equipment.

[0069] The omnidirectional moving mechanism 12 can be controlled by a portable remote controller to flexibly drive the remote-controlled transport vehicle according to the actual site conditions. During omnidirectional movement, the motor provides stable power to the Mecanum omnidirectional wheels 122 through a reducer, ensuring that the vehicle can move quickly to the designated destination and precisely control the direction of travel to transport the aircraft fuselage 3 to the target location.

[0070] Unloading phase

[0071] Position adjustment: After the remote-controlled moving vehicle moves the aircraft fuselage 3 to the target location, the omnidirectional driving mechanism 12 and the suspension mechanism 13 are used again to finely adjust the position and height of the vehicle so that the placement angle and height of the aircraft fuselage 3 are precisely matched with the predetermined unloading position.

[0072] Uninstallation

[0073] By controlling the first and second telescopic mechanisms 29 with a remote controller, the first and second flip support plates 27 are gradually restored to their initial state, releasing the support and contact state of the aircraft fuselage 3.

[0074] The screw elevator 222 of the control lifting mechanism 22 slowly descends, reducing the height of the support structure and allowing the aircraft fuselage 3 to be placed stably at the target location.

[0075] Remove the connection and fixing device to the aircraft fuselage 3, and use the omnidirectional driving mechanism 12 to drive the remote-controlled transfer vehicle away from the unloading site.

[0076] Specific examples have been used to illustrate the principles and implementation methods of the utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of the utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the utility model.
