Description

Technical Field

[0001] This invention relates to the field of intelligent connected vehicle technology, specifically to an intelligent connected vehicle simulation test platform. Background Technology

[0002] Intelligent connected vehicles refer to the organic combination of vehicle networking and intelligent vehicles. They are equipped with advanced onboard sensors, controllers, actuators and other devices, and integrate modern communication and network technologies to achieve intelligent information exchange and sharing between vehicles, people, roads and back-end systems. This enables safe, comfortable, energy-saving and efficient driving, and ultimately, a new generation of cars that can replace human operation. Before being put into use, intelligent connected vehicles need to undergo simulation testing on a platform to test various indicators of the intelligent connected vehicles.

[0003] However, after using existing simulation testing platforms, the following shortcomings were found:

[0004] 1. Currently, when simulating car crashes, existing crash tests generally involve a frontal impact on the front of the car, which prevents the windshield from being impacted simultaneously. This results in a limited range of impact methods. Consequently, existing technologies cannot impact the windshield or the side of the car simultaneously with the front impact, requiring multiple adjustments to the position of the impactor to simulate the impact on the front and side of the car, thus increasing the testing time.

[0005] 2. When simulating bumps in a car, existing simulations involve vibrating the platform up and down to make the car bumpy. However, existing technologies cannot adjust the vibration amplitude of the platform to make the car bumpy at different amplitudes. At the same time, they cannot simulate left and right bumps, making the simulated bumpy state of the car relatively uniform. This affects the accuracy of the car's bumpy state in simulation tests. Summary of the Invention

[0006] (a) Technical problems to be solved

[0022] (III) Beneficial Effects

[0023] Compared with the known prior art, the technical solution provided by this invention has the following beneficial effects:

[0024] 1. By setting up a lead screw, rotating sleeve, impact ramp, and impact block, the lead screw rotates to drive the impact ramp and impact block to reciprocate, and the impact angle of the impact ramp and impact block is adjusted simultaneously. This simulates multiple impacts on the front of the car and the windshield, eliminating the need for the user to perform multiple operations to simulate multiple impacts on the windshield. This makes it easier for the user to operate and tests the wear degree of car parts under the impact of different shaped impact objects. It simulates the impact of different impact objects encountered by the car in daily use, improves the realism of the impacts on the car during use, and thus tests the impact resistance quality of the front of the car and the windshield.

[0025] 2. The system comprises a first fixed rod, a first driving block, a second impact plate, and a semicircular block. The rotation of the first driving block drives the second impact plate and the semicircular block to reciprocate, simulating an impact on the side of the car while simultaneously subjecting the side window to multiple impacts. This tests the wear and tear on the side window under various impact forces, realistically simulating the impact or multiple impacts on the side of the car and its side window. The rotation of the first fixed rod controls the synchronous rotation of the lead screw and the first driving block, while the lead screw can be rotated independently to simulate the synchronous impact process of the front of the car, the windshield, and the side of the car. It can also simulate the impact process of the front of the car and the windshield separately, ensuring the realism of the simulated impact process and simulating all impact situations that a car would experience in actual use.

[0026] 3. The test platform consists of a test platform body, a second drive block, a fixed column, and a vibrating cylinder. The second drive block rotates while simultaneously moving the vibrating cylinder up and down, causing it to impact the bottom of the test platform body. This vibrates the test platform body, simulating the up-and-down bumping motion of a car. When the car is driven on uneven roads, this simulates the damage to internal car parts caused by the bumps. By rotating the fixed column, the rotation amplitude of the third drive block is adjusted, thereby adjusting the vibration intensity of the vibrating cylinder on the test platform body. This results in different levels of bumps on the test platform body, simulating the varying degrees of bumps a car experiences when driven on uneven roads.

[0027] 4. By setting up an arc-shaped protrusion, a third fixed rod, a fourth rotating block, and an impact column, the fourth rotating block rotates, causing the impact column to reciprocate and the third fixed rod to rotate. This causes the impact column to impact the arc-shaped protrusion, resulting in the test platform body vibrating left and right under the vibration of the arc-shaped protrusion. This limits the synchronous movement of the impact column and the vibrating cylinder, and also allows for the independent movement of the vibrating cylinder. This allows for the simulation of both vertical and horizontal bumps of a car, enriching the diversity of simulated bump conditions. After the bump simulation is completed, damaged parts inside the car can be inspected, and damaged parts can be replaced with higher-quality parts, ensuring the car's longevity and reducing the frequency of parts replacement, thus guaranteeing the durability of parts during the car's use.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0047] The present invention will be further described below with reference to embodiments.

[0048] This embodiment provides a simulation test platform for intelligent connected vehicles, such as... Figure 1 As shown, it includes a support assembly 100, which includes a support base plate 101 and support springs 102. Multiple support springs 102 are symmetrically fixedly connected to the top of the support base plate 101, and a ramp is provided at the top of the support assembly 100.

[0049] In view of the aforementioned support component 100, it can be specifically implemented as follows:

[0050] The top of the support component 100 is provided with a multi-directional impact mechanism 300. The multi-directional impact mechanism 300 simulates a surface impact on the front of the car and a point impact and surface impact on the windshield of the car by adjusting the angle of the impact object, and simultaneously conducts impact tests on the windshield and the side of the car.

[0051] As a preferred embodiment of this example, Figure 3 , Figure 6 and Figure 7 As shown, the multi-directional impact mechanism 300 includes a first mounting shaft 301, which is located above the support base plate 101. One end of the first mounting shaft 301 has a first mounting hole for mounting the motor power output shaft. The other end of the first mounting shaft 301 is fixedly connected to a pulley 302.

The top end of the base 308 is provided with an impact inclined plate 309 and an impact block 310. A connecting plate 322 is fixedly connected to the side of the impact inclined plate 309 near the rotating sleeve 323. The connecting plate 322 is rotatably connected to the rotating sleeve 323. One end of the connecting plate 322 is fixedly connected to the side of the impact block 310 near the rotating sleeve 323. A second fixing rod 324 is provided on the outer surface of the central column of the base 308. The second fixing rod 324 passes through the outer surface of the central column of the base 308.

The through-hole on the outer surface of the central column of the base 308 is directly opposite to the rod groove. One end of the second fixing rod 324 is threaded to the inner wall of the rod groove. The second fixing rod 324 is used to restrict the rotation state of the rotating sleeve 323. By adjusting the angles of the impact ramp 309 and the impact block 310, the car windshield can be subjected to impact forces from objects of different shapes.

[0052] As a preferred embodiment of this example, Figure 3 , Figure 4 and Figure 5As shown, a drive shaft 311 is fixedly connected to the rear end of the pulley 302 on the left side.

[0053] Compared with existing technologies, the simulator adjusts the impact angles of the impact ramp 309 and the impact block 310, as well as the rotation of the first fixing rod 312, to simulate multiple impacts on the front of the car and the windshield, as well as the side of the car, and to the windshield and the side windows of the car. Simultaneously, it simulates the impacts of different objects on the windshield, ensuring the realism of the car in the simulated impact process, thereby simulating all the impact situations that a car would be subjected to in actual use.

[0054] At other levels, this embodiment also provides a mechanism capable of simulating the bumpy conditions of a car, such as...

The bottom end of the third fixing rod 419 is inserted into the outer surface of the central shaft of the third gear 417. The third fixing rod 419 is used to limit the rotation state of the central shaft of the third gear 417. The end of the central shaft of the third gear 417 near the test platform body 201 is fixedly connected to a fourth... A drive rod 421 is rotatably connected to the back of the fourth rotating block 420. At least three impact pillars 422 are provided on the left side of the test platform body 201. One end of the drive rod 421 near the impact pillar 422 is rotatably connected to the central pillar of the impact pillar 422. A connecting rod 423 is provided on the left side of the test platform body 201 near the fourth rotating block 420. Both ends of the connecting rod 423 are fixedly connected to the outer surface of the impact pillar 422. A limit rod 424 is fixedly connected to the bottom end of the impact pillar 422. The bottom end of the limit rod 424 is slidably connected to the top end of the support base plate 101. By rotating the third fixed rod 419, the central axis of the second bevel gear 416 is disconnected or connected to the central axis of the third gear 417, thereby simulating the up-and-down and left-and-right bumping state of a car simultaneously, and also simulating the up-and-down bumping state of a car separately.

[0057] Compared with existing technologies, by rotating the third fixed rod 419, the simulator removes the restriction from the third fixed rod 419 between the central axis of the second bevel gear 416 and the central axis of the third gear 417. This allows for the simulation of the up-and-down bumping of a car, as well as the simultaneous simulation of the up-and-down and left-and-right bumping of a car. This enriches the diversity of the simulated bumping conditions, enabling the inspection of damaged parts inside the car after the bumping simulation is completed. Damaged parts can then be replaced with higher-quality parts, allowing the car to be used for a longer period of time, reducing the frequency of parts replacement, and ensuring the durability of parts during the use of the car.

[0058] In this embodiment, a mechanism for fixing a car is provided, such as... Figure 1 As shown, a fixing clamping component 200 is provided at the top of the support component 100. The fixing clamping component 200 includes a test platform body 201, which is located above the support base plate 101 and is used to fix the car. The clamping distance can be adjusted according to the car size.

[0059] like Figure 1 As shown, the test platform body 201 is fixedly connected to the other end of the support spring 102. The top of the test platform body 201 is symmetrically slidably connected to a clamping plate 202. A turntable 203 is provided at the top of the test platform body 201. A first screw 204 is fixedly connected to the central axis of the turntable 203. The first screw 204 is rotatably connected to the side of the clamping plate 202 near the turntable 203. The first screw 204 is threadedly connected to the top of the test platform body 201. At least three arc-shaped protrusions 205 are fixedly connected to the side of the test platform body 201 away from the multi-directional impact mechanism 300.

[0060] Compared with existing technologies, by moving the clamping plate 202 in opposite directions, the car will not be displaced due to bumps or impacts in the simulated bumpy or impact state, thus ensuring that the car will not be affected by displacement in the simulated bumpy or impact state.

[0061] Working principle:

[0062] Initial limitations: Before simulating bumps or impacts, the drive shaft 311 and the rotating shaft 313 are disconnected. At this time, the distance between one end of the first drive block 315 and one end of the first rotating block 314 is at its maximum. At this time, the clamping distance between the clamping plates 202 is at its maximum. The central axis of the third gear 417 and the central axis of the second bevel gear 416 are disconnected. The rotating sleeve 323 and the base 308 are in a fixed state.

[0063] Car fixing and clamping steps:

[0064] Depend on Figure 1As shown, the car is first driven up the ramp at the top of the support base plate 101 onto the test platform body 201, so that the car is positioned between the clamping plates 202. Then, the user manually rotates the turntable 203, which drives the first screw 204 to rotate. Since the first screw 204 is threaded to the top of the test platform body 201 and rotatably connected to one side of the clamping plate 202, the first screw 204 rotates while driving the clamping plate 202 to move on the test platform body 201, so that the clamping plate 202 clamps the car and fixes the car on the test platform body 201, preventing the car from moving randomly in the simulation state.

[0065] Steps for simulating a car crash:

[0066] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, before use, the user first marks the drive shaft 311, the first fixed rod 312, and the rotating shaft 313 with a marker pen when they are on the same horizontal line. The mark is a line. By rotating the second fixed rod 324, since one end of the second fixed rod 324 is threaded to the inner wall of the rod groove on the rotating sleeve 323, one end of the second fixed rod 324 is disengaged from the rod groove on the rotating sleeve 323. This removes the restriction on the rotation between the rotating sleeve 323 and the central column of the base 308, allowing the rotating sleeve 323 to rotate on the central column of the base 308. The impact angle is then adjusted to impact the inclined plate 309 or the impact block 3. Adjustment is performed at 10, with each rotation possible in 45-degree increments or multiples thereof. This avoids fixing the rotating sleeve 323 to the central pillar of the base 308 after the angle adjustment is complete. After adjustment, the second fixing rod 324 is rotated again to fix the rotating sleeve 323 to the central pillar of the base 308. By adjusting the impact angle of the impact ramp 309 or impact block 310, the car windshield is subjected to impacts from various angles, thereby testing the wear and tear of car parts under impacts from objects of different shapes. This simulates the impacts encountered by cars during daily use, improving the realism of impacts experienced by cars during operation.

[0067] When simulating a collision between the front of a car and its windshield, the motor switch fixedly connected to one end of the first mounting shaft 301 is turned on. The motor's power output shaft drives the first mounting shaft 301 to rotate. The first mounting shaft 301 drives the pulley 302 to rotate at both ends. Since a lead screw 303 is fixedly connected to the end of the pulley 302 near the first mounting shaft 301, the pulley 302 rotates while simultaneously driving the lead screw 303 to rotate. Because a slider 304 is threaded onto the outer surface of the lead screw 303, the lead screw 303 rotates while simultaneously moving the slider 304. The slider 304 moves the L-shaped rod 305, which in turn moves the first impact plate 306. The first impact plate 306 moves the first spring 307, which in turn moves the base 308. The rotating sleeve 323 moves, which in turn moves the connecting plate 322. The connecting plate 322 then moves the impact ramp 309 and the impact block 310. One side of the base 308 impacts the front of the car. The impact ramp 309 or the impact block 310, after the angle is adjusted, impacts the windshield. When the impact ramp 309 or the impact block 310 impacts the windshield, the reaction force of the impact ramp 309 or the impact block 310 bounces it away. The impact ramp 309 or the impact block 310 compresses the first spring 307, causing the first spring 307 to deform. After bouncing away, the impact ramp 309 or the impact block 310 impacts the windshield again due to the deformation of the first spring 307, thus simulating the state of multiple impacts on the windshield. This allows the user to achieve multiple impacts on the windshield without having to perform multiple operations, making it easier for the user to operate.

[0068] When simulating an impact on the front end, windshield, and one side of a car, observe whether the marks made on the drive shaft 311, the first fixed rod 312, and the rotating shaft 313 are on the same horizontal line. If they are, turn off the motor switch fixed to one end of the first mounting shaft 301. Rotate the first fixed rod 312 to bring it back to the outer surface of the rotating shaft 313, so that the bottom end of the first fixed rod 312, via a thread, enters the penetration point on the outer surface of the rotating shaft 313. The rotational state of the drive shaft 311 is restricted together with the restricted state of the rotating shaft 313. Therefore, when the motor switch fixedly connected to one end of the first mounting shaft 301 is turned on again, the first mounting shaft 301 drives the pulley 302 to rotate. The end of the pulley 302 away from the first mounting shaft 301 drives the drive shaft 311 to rotate. During the rotation of the drive shaft 311, the rotating shaft 313 drives the first rotating block 314 to rotate. The first rotating block 314 drives the first driving block 315 to rotate. The protrusion on the first driving block 315 presses against the drive frame 316, causing the drive frame 316 to be supported by the bottom. The plate 101 slides, thereby driving the frame 316 to move the connecting rod 317. The connecting rod 317 drives the second impact plate 318 to move, the second impact plate 318 drives the second spring 319 to move, and the second spring 319 drives the semicircular block 320 to move, impacting one side of the car. When the semicircular block 320 impacts one side of the car, the reaction force generated by the semicircular block 320 impacting the car pushes the semicircular block 320 away, thereby causing the semicircular block 320 to compress the second spring 319, causing the second spring 319 to deform. After being pushed away, the semicircular block 320 passes through the second spring 319. The deformation of the shaft re-impacts one side of the car, thus simultaneously simulating the impact state on the front of the car, the windshield, and one side. This allows the drive shaft 311 to rotate while simultaneously driving the rotating shaft 313, or the drive shaft 311 to rotate independently. This enables the simulation of the impact process of the front of the car, the windshield, and the side of the car, as well as the independent simulation of the impact process of the front of the car and the windshield. This ensures the realism of the car in the simulated impact process, thereby simulating all the impact situations that the car will be subjected to in actual use, and thus testing the impact resistance quality of the front of the car and the windshield.

[0069] When it is necessary to adjust the distance between one end of the first driving block 315 and one end of the first rotating block 314, the second screw 321 is rotated. Since the second screw 321 is threadedly connected to the inner wall of the through-hole on the first rotating block 314, the second screw 321 can move on the inner wall of the through-hole on the first rotating block 314, so that the first rotating block 314 drives the first driving block 315 to move, thereby adjusting the distance between one end of the first driving block 315 and one end of the first rotating block 314, adjusting the distance between the semicircular block 320 and the side of the car, reducing the movement time of the semicircular block 320, and making the semicircular block 320 hit the side of the car faster.

[0070] Steps to simulate a car bumpy ride:

[0071] First, mark the central axis of the third gear 417, the central axis of the second bevel gear 416, and the third fixed rod 419 when they are on the same horizontal line. The marking method is the same as described above. At this time, the central axis of the third gear 417 and the central axis of the second bevel gear 416 are disconnected. The user rotates the fixed column 411 clockwise, so that the third rotating block 406 and the third driving block 407 are no longer restricted by the fixed column 411. The user pulls the third driving block 407, so that the third driving block 407 slides in the third rotating block 406, thereby driving the connecting frame 408 to move, thereby adjusting the bottom length of the connecting frame 408, and then adjusting the moving distance of the connecting frame 408, thereby adjusting the vibration force of the vibration cylinder 409 on the test platform body 201, so that the car produces different levels of bumps on the test platform body 201, thereby simulating the bumps produced when the car is used on an uneven road.

[0072] Then, by turning on the motor switch fixedly connected to one end of the second mounting shaft 401, the power output shaft of the motor drives the second mounting shaft 401 to rotate. The second mounting shaft 401 drives the first gear 402, which is close to the second mounting shaft 401, to rotate. Since the first gear 402 is transmitted through the first toothed belt 403, the two first gears 402 rotate synchronously, thereby driving the second rotating block 404, which is located at the bottom of the test platform body 201 and is symmetrical to each other, to rotate. The second rotating block 404 drives the second driving block 405 to rotate, the second driving block 405 drives the third driving block 407 to rotate, and the third driving block 407 drives the third rotating block 406 to rotate. Since the connecting frame 408 is rotatably connected to the second driving block 405 and the third driving block 407, the second... The rotation of the drive block 405 and the third drive block 407 drives the connecting frame 408 to move, and the connecting frame 408 drives the vibrating cylinder 409 to move, so that the inner wall of the vibrating cylinder 409 squeezes the vibrating rod 206, causing the vibrating rod 206 to vibrate, and causing the test platform body 201 to vibrate, thereby simulating the bumpy state of a car on the top of the test platform body 201, thus simulating the damage to the internal parts of the car caused by the bumpy state when the car is used on an uneven road. When the second drive block 405 starts to rotate, the second drive block 405 drives the connecting frame 408 to descend slowly, and the connecting frame 408 drives the vibrating cylinder 409 to descend. By setting the third spring 410, the vibrating cylinder 409 has a buffering effect during the descent.

[0073] When the central shafts of the third gear 417, the second bevel gear 416, and the markings on the third fixed rod 419 are on the same horizontal line, turn off the motor switch fixedly connected to one end of the second mounting shaft 401, rotate the third fixed rod 419 to the outer surface of the central shaft of the third gear 417, so that the bottom end of the third fixed rod 419 is inserted into the outer surface of the central shaft of the third gear 417, connecting the central shaft of the third gear 417 with the central shaft of the second bevel gear 416, turn on the motor switch fixedly connected to one end of the second mounting shaft 401, so that the power output shaft of the motor drives the second mounting shaft 401 to rotate, the second mounting shaft 401 drives the first gear 402 to rotate, and the first gear 402 drives the second gear 416 to rotate. The second rotating block 404 rotates, driving the connecting frame 408 to rotate. The connecting frame 408 drives the third rotating block 406 to rotate, and the third rotating block 406 drives the connecting shaft 412 to rotate. Since the second gear 413, located at the bottom of the test platform body 201 and symmetrical to each other, is driven by the second toothed belt 414, the connecting shaft 412 drives the two second gears 413 to rotate synchronously. The second gear 413 drives the first bevel gear 415 to rotate. Since the first bevel gear 415 and the second bevel gear 416 mesh and transmit power to each other, the first bevel gear 415 drives the second bevel gear 416 to rotate during its rotation. The second bevel gear 416 drives the third gear 417, which is close to the second bevel gear 416, to rotate. 7. Driven by the third toothed belt 418, the two third gears 417 rotate synchronously, causing the third gears 417 to drive the fourth rotating block 420 to rotate. Since the back of the fourth rotating block 420 is rotatably connected to the drive rod 421, the fourth rotating block 420 drives the drive rod 421 to rotate during rotation. Since the end of the drive rod 421 near the impact post 422 is rotatably connected to the center post of the impact post 422, the drive rod 421 compresses the impact post 422 during rotation, causing the impact post 422 to move under the limit of the limiting rod 424. Multiple impact posts 422 move synchronously through the connection of the connecting rod 423, thereby impacting the arc-shaped protrusion 205 on one side of the test platform body 201. The impact causes the arc-shaped protrusion 205 to vibrate, transmitting the vibration force to the test platform body 201. This causes the test platform body 201 to stretch the support spring 102, resulting in deformation of the support spring 102. When the vibration force disappears, the test platform body 201 automatically resets due to the deformation of the support spring 102, thus simulating the left-right bumping state of a car. This allows for the independent simulation of up-and-down bumping, as well as simultaneous simulation of left-and-right bumping, increasing the diversity of simulated bumping states. After the bumping state simulation is completed, damaged internal parts can be inspected and replaced with higher-quality parts, ensuring the car's longevity.This reduces the frequency of parts replacement in a car, ensuring the durability of parts during use.
