[0041] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0042] The following describes a system and method for a vehicle safety island collision test proposed in accordance with an embodiment of the present application with reference to the accompanying drawings. First, the system for a vehicle safety island collision test proposed in accordance with an embodiment of the present application will be described with reference to the accompanying drawings.

[0043] Figure 1 It is a block diagram of a system for a vehicle safety island collision test according to an embodiment of the present application.

[0044] For example, Figure 1As shown, the system 10 for the vehicle safety island collision test includes: a safety island device 100, a traction device 200 and a braking device 300, wherein the safety island device 100 includes a safety island barrier mounting plate 101 and a safety island barrier 102, and the safety island barrier mounting plate 101 is provided with a waist-shaped mounting hole for adjusting the position of the safety island barrier 102; the traction device 200 is used to tow the vehicle to be tested so that the vehicle to be tested hits the safety island device 100 at a preset speed and a preset angle; the braking device 300 is connected to the traction device 200, and the braking device 300 is used to brake the vehicle to be tested when the distance from the safety island device 100 to the test device meets the preset distance, so as to simulate the collision of the vehicle to be tested in front of the safety island device 100.

[0045] Among them, the preset speed and the preset angle can be values ​​pre-set by researchers in this field, or values ​​obtained through a limited number of experiments, or values ​​obtained through a limited number of computer simulations, and are not specifically limited here.

[0046] Specifically, combined Figure 2 As shown, in the embodiment of the present application, the system 10 for the vehicle safety island collision test includes multiple key components, which are composed of a safety island device 100, a traction device 200 and a brake device 300. Among them, the safety island device 100 is composed of a safety island barrier mounting plate 101 and a safety island barrier 102. The waist-shaped mounting hole is specially designed on the safety island barrier mounting plate 101, so that the position of the safety island barrier 102 can be adjusted according to the different widths of various types of vehicles and different safety island collision positions through the waist-shaped mounting hole of the safety island mounting plate, so as to achieve the purpose of adapting to different models and different safety island collision positions. Next, the traction device 200 is mainly used to traction the vehicle to be tested, and ensure that the vehicle to be tested can accurately hit the safety island device 100 at a preset speed and a preset angle. The brake device 300 is connected to the traction device 200, and is used to perform a braking operation immediately when the vehicle to be tested reaches a preset distance from the safety island device 100 during the driving process of the vehicle to be tested, and the vehicle to be tested can be separated from the traction device 200, so that the vehicle to be tested can slide freely to hit the safety island device 100. In this way, the braking device 300 can effectively simulate the real scenario in which the vehicle to be tested collides with the safety island device 100 under actual circumstances, thereby providing important data support for the evaluation of the vehicle's safety performance.

[0047] Optionally, in some embodiments, the preset distance is 0.5m to 1m.

[0048] Optionally, in some embodiments, Figure 3As shown, the traction device 200 includes: a tongue depressor 201, a traction column 202 and a first guide wheel 203, wherein the traction column 202 is used to rotate around a preset center after being subjected to force in a free state to separate the vehicle to be tested and the traction device 200; the first guide wheel 203 is used to drive the traction device 200 to run along a preset track.

[0049] Specifically, a first guide wheel 203 is installed on the traction device 200, which can drive the traction device 200 to run along a preset track under the traction of the traction steel cable; the traction column 202 can withstand external force in a free state and rotate around a preset central axis, thereby achieving effective separation of the traction device 200 from the vehicle to be tested.

[0050] Optionally, in some embodiments, Figure 3 As shown, the brake device 300 includes a guide rod 301, a second guide wheel 302 and a rubber block 303, wherein the guide rod 301 is inserted into the pin hole of the traction column 202, and the guide rod 301 presses the traction cable onto the traction device 200 through the pressing tongue 201, so that the brake device 300 is connected to the traction device 200 through the guide rod 201; the second guide wheel 302 is used to drive the brake device 300 to run along a preset track; the rubber block 303 is used to absorb and mitigate the impact force generated when the vehicle to be tested brakes.

[0051] Specifically, a second guide wheel 302 is installed on the brake device 300, and under the traction of the traction device 200, the brake device 300 can be driven to run along a preset track; the guide rod 301 presses the traction cable tightly onto the traction device 200 through the pressing tongue 201, and at the same time the guide rod 301 is inserted into the pin hole of the traction column 202, thereby connecting the brake device 300 to the traction device 200; the brake device 300 also includes a rubber block 303, which has a brake buffering function. When the vehicle to be tested performs a braking operation, the rubber block 303 can absorb and reduce the impact force generated during the braking process, thereby ensuring the safety and reliability of the entire test process.

[0052] Optionally, in some embodiments, a bearing or a bushing is disposed at the central portion of the traction column 202 so that the main body of the traction column 202 can rotate freely around a preset center.

[0053] That is to say, a bearing or a sleeve structure is provided in the central area of ​​the traction column 202, so that the main body of the traction column 202 can rotate freely around a preset center point.

[0054] According to the system of vehicle safety island collision test proposed in the embodiment of the present application, the to-be-tested vehicle can be towed by the towing device so that the to-be-tested vehicle hits the safety island device at a preset speed and a preset angle; the to-be-tested vehicle can be braked by the braking device when the distance from the safety island device to the to-be-tested vehicle meets the preset distance, so as to simulate the collision of the to-be-tested vehicle in front of the safety island device. Therefore, the system of vehicle safety island collision test can solve the problem of the prior art lacking verification of occupant protection when the vehicle collides with the safety island during driving before the vehicle leaves the factory, thereby improving the safety performance and crashworthiness of the vehicle.

[0055] To facilitate those skilled in the art to further understand the system of the vehicle safety island collision test proposed in the embodiment of the present application, the method of the vehicle safety island collision test proposed in the embodiment of the present application is described below with reference to the accompanying drawings.

[0056] Figure 4 It is a flow chart of a method for a vehicle safety island collision test according to an embodiment of the present application.

[0057] like Figure 4 As shown, the vehicle safety island collision test method adopts Figure 1 The vehicle safety island collision test system of an embodiment, wherein the method comprises the following steps:

[0058] In step S401, the traction device is controlled to run along a preset track under the traction of the traction cable, and the vehicle to be tested is driven to run along the preset track through the traction column.

[0059] Specifically, the starting device can control the traction device to run along the preset track under the traction of the traction cable, and the traction column in the traction device can be used to drive the vehicle to be tested to run along the preset track.

[0060] In step S402, when the test vehicle travels to a distance from the safety island device that meets a preset distance, the brake device is controlled to brake and the traction column is flipped to separate the test vehicle and the traction device, so that the test vehicle can slide freely and collide with the safety island device.

[0061] Specifically, since the brake device is connected to the traction device through a guide rod, when the traction device moves, the brake device can be driven by the guide rod to run along the preset track, and when the distance between the vehicle to be tested and the safety island device reaches the preset distance (0.5m~1m), the system will automatically control the brake device to perform a braking operation. At the same time, the brake device pulls and presses the tongue through the guide rod, and the guide rod is pulled out of the pin hole of the traction column, and the traction column flips, thereby successfully separating the vehicle to be tested from the traction device. As a result, the vehicle to be tested can slide freely without external traction, and eventually collide with the safety island device to test the safety performance of the vehicle.

[0062] Furthermore, in some embodiments, after allowing the vehicle to be tested to slide freely and collide with the safety island device, it also includes: acquiring sensor data and video signals of the vehicle to be tested during the collision process; and analyzing and evaluating the safety performance of the vehicle to be tested based on the sensor data and video signals.

[0063] That is to say, during the free sliding collision safety island of the vehicle to be tested, various sensor data and video signals of the vehicle to be tested can be obtained through data acquisition equipment. These sensor data include but are not limited to real-time monitoring information of various physical quantities such as acceleration, speed, pressure, temperature, etc., and the video signal provides an intuitive record of the collision process. Based on these collected sensor data and video signals, data processing, interpretation and detailed review of video materials are carried out to ensure that the safety performance of the vehicle to be tested in the event of a collision can be accurately evaluated. The evaluation content may include key safety indicators such as the stability of the vehicle structure, the effectiveness of the occupant protection system, and whether the vehicle can maintain the normal operation of key functions after a collision.

[0064] Furthermore, in some embodiments, before controlling the traction device to run along a preset track under the traction of the traction cable, it also includes: weighing and counterweighting the vehicle to be tested so that the total mass of the vehicle to be tested meets the preset mass requirements; installing on-board data acquisition equipment and acceleration sensors, and adjusting the seat position and dummy position in the vehicle to be tested to meet preset conditions.

[0065] It is understandable that some preparations can be done before the collision test. First, the vehicle to be tested needs to be weighed, and after weighing, the vehicle to be tested needs to be counterweighted (such as adding or removing counterweights at specific parts of the vehicle, etc.) to ensure that its total mass meets the preset quality requirements. This step is crucial because it directly affects the accuracy and reliability of subsequent tests. After completing the counterweight work, the necessary on-board data acquisition equipment can be installed to record various parameters of the vehicle during the test in real time, such as speed, acceleration, steering angle, etc., to provide a detailed basis for subsequent data analysis. In addition, acceleration sensors need to be installed at key parts of the vehicle. These sensors can accurately measure the acceleration changes of the vehicle during the dynamic process and provide important data for evaluating the dynamic performance of the vehicle.

[0066] After the equipment is installed, the interior of the vehicle to be tested needs to be adjusted to ensure that the position of the seat and the placement of the dummy meet the preset conditions. That is, first, adjust the height of the seat to the lowest position to ensure that the longitudinal position of the seat is at the midpoint of the front and rear, and then use the 3DH measurement method (three-dimensional height measurement method) is a technology used to obtain the three-dimensional shape and height information of the surface of an object) to adjust the angle of the seat back to 25 degrees. Next, measure the actual distance between the H point of 3DH and the center point of the surface of the front door lock mounting bolt. In order to ensure the correct installation of the seat, it is necessary to compare and analyze this actual measured distance with the theoretical standard distance. If a deviation is found, it is necessary to make corresponding adjustments based on the analysis results until this distance is completely consistent with the theoretical value. After the adjustment work is completed, the coordinates of the H point at this time can be recorded. Next, place the dummy model on the seat of the vehicle to be tested, adjust the H point position of the dummy model, and ensure that it is completely consistent with the H point position obtained by the 3DH measurement method. When the H point position of the dummy model meets the requirements, record the H point coordinates of the dummy model, and also record the coordinate deviation value between the 3DH coordinates. Finally, in order to ensure the symmetry and balance of the vehicle to be tested, it is necessary to accurately determine the front and rear centerline of the vehicle and affix a clear mark on the centerline for subsequent reference and use.

[0067] Furthermore, in some embodiments, after adjusting the seat position and the dummy position in the vehicle to be tested to meet preset conditions, it also includes: adjusting the waist-shaped mounting holes on the safety island barrier mounting plate so that the current position of the safety island barrier coincides with the preset collision point; placing the vehicle to be tested on a preset track, and adjusting the center line of the vehicle to be tested to be consistent with the center line of the preset track.

[0068] That is to say, after adjusting the vehicle to be tested and the dummy model, the position of the safety island device can also be adjusted by carefully adjusting the waist-shaped mounting holes on the safety island barrier mounting plate to ensure that the position of the safety island barrier of the safety island device can accurately correspond to the preset collision point. Next, the vehicle to be tested is placed on the preset track. In order to ensure the accuracy of the test, it is necessary to ensure that the center line of the vehicle to be tested is completely consistent with the center line of the preset track, thereby providing an accurate benchmark for subsequent collision tests.

[0069] According to the method of vehicle safety island collision test proposed in the embodiment of the present application, through the system of vehicle safety island collision test, the problem that the prior art lacks verification of occupant protection when the vehicle collides with the safety island during driving before the vehicle leaves the factory can be solved, thereby improving the safety performance and crash resistance of the vehicle.
