Abstract
Description
Technical Field
[0001] This invention relates to the field of safety testing technology, and more specifically, to a device and method for simulating the fall of a flying car. Background Technology
[0002] Current safety testing of flying cars primarily relies on simulations or static experiments, lacking testing equipment capable of realistically reproducing the freefall or crash process of flying cars in real-world scenarios. Existing testing equipment typically cannot accurately simulate the physical impacts experienced by flying cars during a crash, especially when evaluating the performance of flying cars and their occupant protection devices; the authenticity and accuracy of test results are often compromised. For example, while existing simulation technologies can simulate crash scenarios to a certain extent, they fail to fully consider the actual physical effects of flying cars under different flight attitudes, fall angles, and speeds, and cannot comprehensively reproduce the dynamic impact processes experienced by flying cars in real-world environments.
[0003] Furthermore, existing flying car crash test equipment has limitations in adaptability, particularly in meeting the testing needs of different types of flying cars. Most existing equipment designs lack flexibility and cannot effectively adapt to the diversity of flying car structures, sizes, and power systems, thus limiting the versatility and universality of the test equipment.
[0004] The reasons for this problem or defect are: The root cause of the above problems lies in the fact that flying cars, as an emerging mode of transportation, have significantly different designs and structures, and existing testing equipment is often unable to meet their specific testing requirements. Existing testing devices are mostly designed based on traditional vehicle or aircraft testing platforms, failing to adequately optimize for the unique operating conditions of flying cars, thus making it impossible to accurately simulate the attitude changes and impact processes of flying cars during actual crashes.
[0005] Furthermore, existing testing equipment generally lacks sophisticated control and monitoring capabilities. Existing testing methods largely rely on static loads or simplified dynamic models, failing to accurately reproduce the complex physical changes during a flying car crash, particularly the effects of impact, vibration, and inertia. These factors are not adequately considered in current technologies, thus limiting the accuracy and comprehensiveness of test results.
[0006] A simulated fall impact testing device includes: a test bench module comprising an impact platform, a frame column, and a traction power assembly; the impact platform is located at the bottom, and the frame column is located on the upper surface of the impact platform; a floor module, slidably connected to the frame column in a vertical direction, the traction power assembly being drively connected to the floor module to drive the floor module to rise in height or accelerate its descent, the floor module impacting the impact platform when it reaches its lowest point; a lower limb simulation module, located on the upper surface of the floor module, the lower limb simulation module having a first state of being adsorbed and connected to the floor module and a second state of being abutting against the upper surface of the floor module; and a detection module for detecting the acceleration and strain of the lower limb simulation module. This simulated fall impact testing device can simulate the scenario of an elevator freely falling or accelerating downwards, testing the impact and damage caused to the human lower limbs by the fall.
[0007] However, existing technologies cannot accurately simulate the attitude changes of flying cars during actual crashes, resulting in the inability to evaluate the performance of flying cars and their occupant protection devices. Therefore, how to invent a flying car crash simulation test device that takes into account the attitude changes of flying cars is a technical problem that urgently needs to be solved in this field. Summary of the Invention
[0008] To address the problem that existing technologies cannot accurately simulate the attitude changes of flying cars during actual crashes, this invention provides a crash simulation testing device and method for flying cars, which features accurate and reliable test data and convenient controllability.
[0009] To achieve the above-mentioned objectives of this invention, the technical solution adopted is as follows: A crash simulation testing device for a flying car includes a main frame, a hoisting mechanism, a crash platform, an attitude control mechanism, a sensing module, a central control module, and an analysis module. The hoisting mechanism is fixedly installed on the top of the main frame, the crash platform is installed on the bottom of the main frame, and the attitude control mechanism is installed on the main frame. The hoisting mechanism is releasably connected to the flying car. The attitude control mechanism is adjustablely connected to the flying car.

The control platform consists of several rigid frames arranged around the flying vehicle. Each rigid frame is movably positioned between two rigid ropes. The control platform also includes several traction ropes for towing the flying vehicle. One end of each traction rope is connected to the junction of two rigid frames, and the other end is detachably connected to the flying vehicle.

[0013] Furthermore, the sensing module includes an acceleration sensor; the sensing module also includes any one or more sensors such as a vibration sensor, a force sensor, a pressure sensor, and a strain sensor.
[0014] Furthermore, the analysis module includes a data acquisition unit, a signal amplifier, an analysis unit, and a storage unit.

[0015] Furthermore, the central control module includes a cascaded data monitoring unit, an interactive interface, and a test scheduling unit. The interactive interface includes a display and operation panel, allowing test personnel to set and operate based on the displayed monitoring information. The data monitoring module receives and monitors the monitoring data output by the sensor module and outputs corresponding monitoring signals to the interactive interface for display. Based on the setting instructions received from the interactive interface, the test scheduling unit schedules the operation of the power motor and all control motors, as well as the hoisting mechanism and attitude control mechanism, to ensure that all mechanisms, platforms, and systems can work collaboratively.

Therefore, this invention solves the problem that existing technologies cannot accurately simulate the attitude changes of a flight car during an actual crash, and it features accurate and reliable test data that can be easily controlled.

Detailed Implementation
[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0026] Example 1 like Figure 1 As shown, a flying car 14 crash simulation test system includes a main frame, a hoisting mechanism, a crash platform 1, an attitude control mechanism, a sensing module, a central control module, and an analysis module. The hoisting mechanism is fixedly installed on the top of the main frame, the crash platform 1 is installed on the bottom of the main frame, and the attitude control mechanism is installed on the main frame. The hoisting mechanism is releasably connected to the flying car 14. The attitude control mechanism is adjustablely connected to the flying car 14. The sensing module is located inside the flying car 14 and is used to monitor sensing data including acceleration. The central control module is connected to the sensing module, the hoisting mechanism, and the attitude control mechanism, respectively, and is used to receive sensing data and control the hoisting mechanism and the attitude control mechanism. The analysis module is connected to the central control module and the sensing module, respectively, and is used to output an evaluation report based on the sensing data and control data.
[0027] In one specific embodiment: the main frame includes a base platform 2, a plurality of support columns 3 mounted on the base platform 2, and a working platform 4 disposed above the plurality of support columns; one end of the hoisting mechanism is fixedly mounted on the working platform 4, and the other end is releasably connected to the flying car 14; the attitude control mechanism is disposed on the working platform 4 and the base platform 2, its horizontal position corresponding to the drop platform 1, and is adjustablely connected to the flying car 14; the drop platform 1 is disposed at the bottom of the main frame.
[0028] In this embodiment, the main frame structure ensures the stable operation of the flying car 14 crash simulation test system during testing. The design of the work platform 4 enables coordination between various devices and provides stable support for operations such as hoisting and status control of the flying car 14. This design ensures the high stability and high reliability of the testing device.
[0029] In this embodiment, the hoisting mechanism consists of a power motor 11, a cable 12, and a hook lock 13, used to hoist the flying car 14 to a designated aerial position. Under the control of the power motor 11, the cable 12 lifts the flying car 14 to a predetermined height. After the hook lock 13 is released, the flying car 14 will perform a freefall maneuver, simulating the actual impact force during the fall of the flying car 14. The precise control of the hoisting mechanism ensures that the flying car 14 quickly reaches the required height during the test and guarantees the accuracy of the fall maneuver.
[0030] In this embodiment, the attitude control mechanism consists of multiple rigid ropes 7, control motors 5, a rigid frame 8, and a traction rope 9 connected to the flying car 14. Through a precise motor control system, this mechanism can adjust key states such as the falling speed and collision angle of the flying car 14, ensuring that the test can simulate the behavior of the flying car 14 under different conditions. During the test, by synchronously controlling the operation of all control motors 5, the falling state of the flying car 14 at different speeds and angles can be accurately simulated. The rigid frame 8 and the rigid ropes 7 work together to fix and constrain the flying car 14 during the fall, thereby preventing excessive swaying or attitude changes during the fall and ensuring the stability and accuracy of the test. Furthermore, the connection between the rigid ropes 7 and the rigid frame 8 is adjustable in length, allowing the device to adapt to flying cars 14 of different sizes and types, and it is easy to install and disassemble, suitable for multiple tests.
[0031] In this embodiment, the drop platform 1 is made of high-strength material, possessing extremely high impact resistance and capable of withstanding the enormous impact force generated when the flying car 14 falls. The platform's design not only considers impact absorption but also features adjustable height and angle functions, simulating different height and angle conditions faced by the flying car 14 during a fall. By adjusting the angle and height of the drop platform under different test scenarios, the fall state of the flying car 14 under various environmental conditions can be simulated, thereby more accurately assessing the safety of the flying car 14 and its occupants.
[0032] In this embodiment, the sensing module is equipped with multiple high-precision sensors capable of real-time monitoring of key physical parameters of the flying car 14, such as speed, acceleration, and vibration, during its descent. The sensor system includes, but is not limited to, accelerometers, force sensors, pressure sensors, and strain sensors. These sensors can accurately capture the physical changes of the flying car 14 during its descent, especially the intense impact force generated when the flying car 14 collides with the ground. The sensors can be installed in multiple key locations on the flying car 14, such as the passenger seats, seat belts, and vehicle structure, to monitor the acceleration, impact force, and pressure experienced by the occupants. This data is transmitted wirelessly in real-time to a data acquisition and analysis system for further analysis.
[0033] In this embodiment, the analysis module includes a data acquisition unit, a signal amplifier, an analysis unit, and a storage unit. The data acquisition unit receives and preprocesses the sensor data input from the sensor module in real time. After being amplified by the signal amplifier, the sensor data is input into the analysis unit along with the control data output from the central control module for analysis. The analysis module stores the evaluation report in the storage unit. The analysis module includes a cascaded data acquisition unit, a signal amplifier, and a data storage unit, enabling high-speed, real-time acquisition and processing of sensor data. Through data analysis, detailed reports on the impact force, acceleration, vibration, and occupant protection effects during the fall of the flying car 14 can be generated. Furthermore, the data analysis system can compare safety results under different test conditions, quantify the survivability assessment of the flying car 14, and provide reliable data support to improve the safety design of the flying car 14.
[0034] In one specific embodiment, the central control module is used to monitor, schedule, and coordinate the operation of all test equipment in real time to ensure the efficiency, accuracy, and safety of the testing process. It includes an interactive interface, a data monitoring unit, and a test scheduling unit. The interactive interface includes a display and operation panel, allowing test personnel to set and operate based on the displayed monitoring information. The data monitoring module receives and monitors the monitoring data output by the sensor modules and outputs corresponding monitoring signals to the interactive interface for display. The test scheduling unit, based on the setting instructions received from the interactive interface, schedules the operation of the power motor and all control motors, as well as the hoisting mechanism and attitude control mechanism, ensuring that all mechanisms, platforms, and systems can work collaboratively. It also includes a safety monitoring unit, used to receive data from the main sensor modules, monitor the safety during the testing process, and issue alarms if potential safety or equipment risks exist.
[0035] In this embodiment, unlike existing technologies that primarily rely on simulation and static testing, the present invention uses physical testing to more realistically and accurately reproduce the fall scenarios of the flying car 14 under different operating conditions. The device simulates the fall of the flying car 14 at various attitudes, speeds, and angles through the coordinated operation of a hoisting mechanism, an attitude control mechanism, and a fall platform. The attitude control mechanism is equipped with multiple rigid ropes 7, a control motor 5, and fixed pulleys 6 to precisely adjust the fall speed, angle, and state of the flying car 14, ensuring stability during the fall. Through its flexible hoisting rope control system and adjustment mechanism, the present invention can adapt to flying cars 14 of different types, sizes, and structures, improving the versatility of the device.

[0042] In one specific embodiment, the sensing module includes an acceleration sensor; the sensing module also includes any one or more sensors such as a vibration sensor, a force sensor, a pressure sensor, and a strain sensor.
[0043] In this embodiment, the sensing module is installed at any one or more locations of the passenger seat, seat belt, or vehicle structure of the flying car 14.
[0044] This embodiment also includes a main sensing module, which includes several motor sensors installed on the power motor 11 and each control motor 5, a force sensor installed on the drop platform 1, and vibration sensors installed on the working platform 4, the control track, and the control platform. This embodiment also includes monitoring cameras installed on the drop platform 1, the working platform 4, the control track, and the flying car 14.
[0045] In one specific embodiment, such as Figure 3 As shown, the analysis module includes a data acquisition unit, a signal amplifier, an analysis unit, and a storage unit. The data acquisition unit receives and preprocesses the sensor data input from the sensor module in real time. After being amplified by the signal amplifier, the sensor data is input into the analysis unit along with the control data output from the central control module for analysis. The analysis module stores the evaluation report in the storage unit.
[0046] In one specific embodiment, such as Figure 4 As shown, the central control module includes a cascaded data monitoring unit, an interactive interface, and a test scheduling unit. The interactive interface includes a display and operation panel, allowing test personnel to set and operate based on the displayed monitoring information. The data monitoring module receives and monitors the monitoring data output by the sensor module and outputs corresponding monitoring signals to the interactive interface for display. Based on the setting instructions received from the interactive interface, the test scheduling unit schedules the power motor 11 and all control motors 5, and schedules the operation of the hoisting mechanism and attitude control mechanism to ensure that all mechanisms, platforms, and systems can work collaboratively. In this embodiment, a safety monitoring unit is also included, which is used to receive data from the main sensing module and monitor the safety during the testing process.
[0047] Example 3 like Figure 5 As shown, a method for simulating the crash of a flying car 14 includes the following specific steps: Construct the aforementioned flying car 14 crash simulation test system; The central control module controls the hoisting mechanism to hoist the flying car 14 to the set position and height within the main frame; In this embodiment, when hoisting the flying car 14, the power motor 11 rotates in the reverse direction to lower the cable 12 and hook lock 13 to directly above the flying car 14. The hoisting strap is used to wrap around the underside of the flying car 14 and is connected to the hook lock 13. Then, the power motor 11 is rotated in the forward direction to make the hoisting strap slightly taut. Connect the flying car 14 to the attitude control mechanism; control the attitude control mechanism through the central control module to set the attitude of the flying car 14; In this embodiment, multiple suspension points are provided around the flying car 14; the flying car 14 is connected to the rigid frame 8 by rigid ropes 7, and the connection between the rigid ropes 7 and the flying car 14 is a disconnectable connection. In this embodiment, based on the actual testing requirements, the initial angle of the flying car 14 is adjusted by asynchronously controlling the control motor 5 and utilizing the difference in the running lengths of the rigid ropes 7. Simultaneously, based on actual testing needs, when certain special test scenarios cannot be achieved using the rigid ropes 7, the angle of the drop platform 1 is adjusted collaboratively to achieve large-angle drop scenarios.
[0048] When the attitude setting is completed and the hoisting mechanism is disconnected from the flying car 14, the rigid rope 7 automatically disconnects to ensure the accuracy of the flying car 14 parameters. In this embodiment, based on actual testing requirements, the central control system uniformly schedules all mechanisms within a safe range. If the height provided by the support column 3 alone is insufficient to meet the testing speed requirements, the central control system coordinates the control motors. Simultaneously, as the hook lock 13 opens, all rigid ropes 7 are synchronously accelerated, while the ratchet assembly 10 limits the speed of the rigid ropes 7 to ensure that the speed does not exceed the platform's tolerance. Furthermore, at a distance of five meters from the drop platform 1, the connection between the rigid ropes 7 and the flying car 14 is disconnected to prevent debris from the flying car 14 from damaging the experimental equipment. Disconnect the hoisting mechanism from the flying car 14; The flying car 14 crashes onto the crash platform 1. During the crash, the attitude control mechanism is controlled by the central control module to adjust the attitude of the flying car 14, and the sensor module continuously monitors the sensor data of the flying car 14, including acceleration. Based on the sensor and control data from the test, the analysis module outputs an evaluation report.
[0049] In this embodiment, the analysis module of the flying car 14 crash simulation test system includes a data acquisition unit, a signal amplifier, an analysis unit, and a storage unit. The data acquisition unit receives and preprocesses the sensor data input from the sensor module in real time. After being amplified by the signal amplifier, the sensor data is input into the analysis unit along with the control data output from the central control module for analysis. The analysis module stores the evaluation report in the storage unit. All data collected by the test device is transmitted to the analysis module. The analysis module inputs the analysis data to the central control module for output. The central control module sends control commands to the test device, which responds by changing its own or the flying car 14's state and feeding back the corresponding state to the central control module.
[0050] In this embodiment, the test control system is used to monitor, schedule, and coordinate the operation of all test equipment in real time, ensuring the efficiency, accuracy, and safety of the test process, with the flying car 14 as the test object. The analysis module collects various sensor data in real time and performs dynamic analysis on the test process. The sensing module is equipped with multiple high-precision sensors, capable of monitoring key physical parameters such as speed, acceleration, and vibration of the flying car 14 during the fall process in real time. Therefore, this test method solves the problem that existing technologies cannot accurately simulate the attitude changes of the flying car 14 during actual fall, and has the characteristics of providing accurate and reliable test data that can be easily adjusted.

Based on the setting instructions received from the interactive interface, the test scheduling unit schedules the operation of the power motor (11) and all control motors, as well as the hoisting mechanism and attitude control mechanism, to ensure that all mechanisms, platforms, and systems can work together.
7. A method for simulating the fall of a flying car, characterized in that: The specific steps include the following: Construct a crash simulation test device for a flying car as described in any one of claims 1 to 6; The central control module controls the hoisting mechanism to hoist the flying car (14) to the set position and height within the main frame; Connect the flying car (14) to the attitude control mechanism; control the attitude control mechanism through the central control module to set the attitude of the flying car (14); Disconnect the hoisting mechanism from the flying car (14); The flying car (14) crashes onto the crash platform (1), and during the crash, the sensor module continuously monitors the vehicle's sensor data, including acceleration. Based on the sensor and control data from the test, the analysis module outputs an evaluation report.
8. The method for simulating the fall of a flying car based on claim 7, characterized in that: The attitude control mechanism is equipped with a control platform that can be controlled to move up and down by the central control module. The control platform is disconnected from the flying car (14). When the flying car (14) falls, the falling speed of the flying car (14) can be adjusted in real time by the attitude control mechanism, and the connection with the flying car (14) can be disconnected at any time.
