Description

Technical Field

[0001] The present invention relates to the technical field of safety testing, and more specifically, to a falling simulation testing device and method for a flying car. Background Art

[0002] The existing safety tests of flying cars mainly rely on simulation or static experiments, and lack test equipment that can truly reproduce the free fall or falling process of flying cars in the scene. Existing test equipment usually cannot accurately simulate the physical impact experienced by flying cars during the fall process, especially when evaluating the performance of flying cars and their occupant protection devices, the authenticity and accuracy of the test results are often not guaranteed. For example, although the existing simulation technology can simulate a certain degree of falling scenarios, it fails to fully consider the actual physical impact of flying cars under different flight postures, falling angles and speeds, and cannot fully reproduce the dynamic impact process experienced by flying cars in real environments.

[0003] In addition, existing flying car drop test devices have limitations in adaptability, especially in meeting the testing needs of different types of flying cars. Most existing device designs lack flexibility and cannot effectively adapt to the diversity of flying car structures, sizes, and power systems, limiting the versatility and universality of the test devices.

[0004] The reasons for this problem or defect:

[0005] The root cause of the above problems is that as a new means of transportation, flying cars have significant differences in design and structure, and existing test equipment is usually difficult to meet their special testing needs. Existing test equipment is mostly designed based on traditional vehicle or aircraft test platforms, and has not been fully optimized for the unique working conditions of flying cars, resulting in the inability to accurately simulate the posture changes and impact process of flying cars in actual falls.

[0006] In addition, existing test devices generally lack sophisticated control and monitoring functions. Existing test methods mostly rely on static loads or simplified dynamic models, which cannot truly restore the complex physical changes during the fall of a flying car, especially the effects of impact force, vibration, and inertia. These factors have not been fully considered in existing technologies, resulting in the accuracy and comprehensiveness of test results being restricted.

[0007] There is a simulated fall impact test device, including: a test bench module, including an impact platform, a frame column and a traction power assembly, the impact platform is arranged at the bottom, and the frame column is arranged on the upper surface of the impact platform; a floor module, which is slidably connected with the frame column in the vertical direction, and the traction power assembly is connected with the floor module in a transmission manner to drive the floor module to increase the height or accelerate the fall, and the floor module hits the impact platform when it falls to the lowest point; a lower limb simulation module, which is arranged on the upper surface of the floor module, and the lower limb simulation module has a first state of adsorption connection with the floor module and a second state of abutting against the upper surface of the floor module; a detection module, which is used to detect the acceleration and strain of the lower limb simulation module. The simulated fall impact test device can simulate the scene of free fall or accelerated fall of the elevator, and test the impact and damage caused by the fall to the lower limbs of the human body.

[0008] However, the existing technology is unable to accurately simulate the posture changes of a flying car during an actual fall, resulting in the inability to evaluate the performance of the flying car and its occupant protection device. Therefore, how to invent a flying car fall simulation test device that takes into account the posture changes of the flying car is a technical problem that urgently needs to be solved in this technical field.

DETAILED DESCRIPTION

[0034] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] like Figure 1As shown, a flying car 14 fall simulation test system includes a main frame, a hoisting mechanism, a fall platform 1, a posture control mechanism, a sensor module, a central control module, and an analysis module; the hoisting mechanism is fixedly installed on the top of the main frame, the fall platform 1 is installed at the bottom of the main frame, and the posture control mechanism is installed on the main frame; the hoisting mechanism is releasably connected to the flying car 14; the posture control mechanism is adjustably connected to the flying car 14; the sensor module is arranged in the flying car 14, and is used to monitor the sensor data including acceleration; the central control module is respectively connected to the sensor module and the hoisting mechanism and the posture control mechanism, and is used to receive the sensor data and control the hoisting mechanism and the posture control mechanism; the analysis module is respectively connected to the central control module and the sensor module, and is used to output an evaluation report based on the sensor data and the control data.

[0037] In a specific embodiment: the main frame includes a base platform 2, a plurality of support columns 3 installed on the base platform 2, and a working platform 4 arranged above the plurality of support columns; one end of the hoisting mechanism is fixedly installed on the working platform 4, and the other end is releasably connected to the flying car 14; the attitude control mechanism is arranged on the working platform 4 and the base platform 2, and its horizontal position corresponds to the falling platform 1, and is adjustably connected to the flying car 14; the falling platform 1 is arranged at the bottom of the main frame.

[0038] In this embodiment, the main frame mechanism ensures that the flying car 14 fall simulation test system can work stably during the test. The design of the working platform 4 enables coordination between various devices and provides stable support for operations such as hoisting and state control of the flying car 14. Through this design, the high stability and high reliability of the test device can be ensured.

[0039] In this embodiment, the hoisting mechanism is composed of a power motor 11, a hoisting motor, a cable 12 and a hook lock 13, which is used to hoist the flying car 14 to a designated aerial position. Under the control of the power motor 11, the hook 12 lifts the flying car 14 to a predetermined height. After the hook 13 is opened, the flying car 14 will perform a free fall action to simulate the actual impact force of the flying car 14 during the fall. The precise control of the hoisting mechanism can ensure that the flying car 14 quickly reaches the required height during the test and ensures the accuracy of the falling action.

[0040] In this embodiment, the attitude control mechanism is composed of a plurality of rigid ropes 7, a plurality of rigid ropes 7, a control motor 5, a rigid frame 8, and a traction rope 9 connected to the flying car 14. The mechanism can adjust the key states such as the falling speed and collision angle of the flying car 14 through a precise motor control system to ensure 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 rope 7 work together to fix and constrain the flying car 14 during the falling process, thereby avoiding excessive swinging or attitude changes of the flying car 14 during the falling process, and ensuring the stability and accuracy of the test. In addition, the connection between the rigid rope 7 and the rigid frame 8 can adjust the length, so that the device can adapt to flying cars 14 of different sizes and types, and is easy to install and disassemble, and is suitable for multiple tests.

[0041] In this embodiment, the falling platform 1 is made of high-strength material and has extremely high impact resistance, and can withstand the huge impact force generated when the flying car 14 falls. The design of the platform not only takes into account the absorption of impact force, but also has adjustable height and angle functions, which can simulate the different heights and angles faced by the flying car 14 when it falls. In different test scenarios, by adjusting the angle and height of the falling platform, the falling state of the flying car 14 under different environmental conditions is simulated, so as to more accurately evaluate the safety of the flying car 14 and its occupants.

[0042] In this embodiment, the sensing module is equipped with a variety of high-precision sensors that can monitor the key physical parameters of the flying car 14 during the fall, such as speed, acceleration, vibration, etc. in real time. The sensor system includes but is not limited to acceleration sensors, force sensors, pressure sensors, and strain sensors, etc. These sensors can accurately capture the physical changes of the flying car 14 during the fall, especially the strong impact force generated when the flying car 14 collides with the ground. Sensors can be installed in multiple key parts of the flying car 14, such as passenger seats, seat belts, body structures, etc., to monitor the acceleration, impact force and pressure experienced by the passengers. These data are transmitted to the data acquisition and analysis system in real time through wireless transmission for further analysis.

[0043] 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 pre-processes the sensor data input to the sensor module in real time, and the sensor data is amplified by the signal amplifier and input into the analysis unit together with the control data output by 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, which can collect sensor data at high speed and in real time and process it. Through data analysis, a detailed report on the impact force, acceleration, vibration, and occupant protection effect of the flying car 14 during the fall process can be generated. In addition, the data analysis system can also compare the 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.

[0044] In a 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 test process, and includes an interactive interface, a data monitoring unit, and a test scheduling unit: the interactive interface includes a display and operation panel, which is used to allow testers to set and operate according to the displayed monitoring information; the data monitoring module receives and monitors the monitoring data output by the sensor module, and outputs the corresponding monitoring signal to the interactive interface for display; the test scheduling unit schedules the power motor and all control motors to schedule the lifting mechanism and posture control mechanism based on the setting instructions received from the interactive interface output to ensure that various mechanisms, platforms, and systems can work together; it also includes a safety monitoring unit, which is used to receive data transmitted by the main sensor module, monitor the safety during the test process, and issue an alarm if there is a possible safety risk or equipment risk.

[0045] In this embodiment, the present invention is different from the prior art that mainly relies on simulation and static testing. It reproduces the falling situation of the flying car 14 under different working conditions more realistically and accurately through physical testing. The device simulates the falling of the flying car 14 under various postures, speeds, and angles through the coordination of the hoisting mechanism, the attitude control mechanism, and the falling platform. The attitude control mechanism is equipped with a plurality of rigid ropes 7, a control motor 5, and a fixed pulley 6 to accurately adjust the falling speed, angle, and state of the flying car 14 to ensure stability during the falling process.

[0066] In this embodiment, according to the actual needs of the test, the control motor 5 is asynchronously controlled, and the initial angle of the flying car 14 is adjusted by the difference in the running length of the rigid rope 7. At the same time, according to the actual test needs, when some special test scenarios cannot be achieved by the rigid rope 7, the angle of the falling platform 1 is coordinated to achieve falling scenarios such as large angles.
