Description

Technical Field

[0001] This utility model relates to the field of automotive safety testing technology, and in particular to a receiving device for calibrating the velocity of a projectile in a pedestrian protection test. Background Technology

[0002] In the development of modern automotive safety technology, pedestrian protection testing plays a crucial role. It is not only a key step in evaluating vehicle safety performance but also a significant driving force for technological advancements and regulatory improvements in the automotive industry. Pedestrian protection tests comprehensively examine a vehicle's ability to protect pedestrians during a collision through carefully designed collision scenarios, such as simulating collisions between a vehicle and a pedestrian's legs and head. These scenarios are designed to realistically reproduce the mechanical environment of actual traffic accidents, ensuring the validity and reliability of the test results. For example, the head model uses a parabolic trajectory in the test to accurately simulate the complex force process experienced by a pedestrian's head after a collision, including upward impact force and forward propulsion force. This simulation not only reflects the physical phenomena in a real collision but also effectively assesses the risk of head injury. Similarly, the leg model uses a horizontal trajectory to simulate the force state of a pedestrian's legs when struck by the front of a vehicle, thereby verifying the protective effect of the vehicle structure on the pedestrian's legs.

[0003] However, while pedestrian protection testing plays an irreplaceable role in improving vehicle safety performance, several aspects of the current pedestrian protection testing process still require optimization. Particularly in the velocity calibration of launchers (such as head and leg models), after completing their simulated collision trajectory, the launchers fall directly to the ground. This not only requires tedious manual retrieval work, increasing labor intensity and reducing efficiency, but also increases the risk of damage due to direct collisions with hard ground surfaces, further driving up testing costs. Furthermore, each damaged launcher necessitates the preparation and calibration of a new model, which is not only time-consuming and labor-intensive but may also introduce testing errors due to slight differences between models, affecting the accuracy and consistency of evaluation results. Therefore, an innovative solution is urgently needed to address the retrieval and protection issues after launcher velocity calibration, simplifying the operation process, improving efficiency, reducing testing costs, and ensuring the accuracy and sustainability of pedestrian protection testing. Utility Model Content

[0004] The purpose of this utility model is to provide a receiving device for calibrating the velocity of projectiles in pedestrian protection tests, so as to solve the problems of projectiles falling directly to the ground after velocity calibration in pedestrian protection tests, which leads to cumbersome manual retrieval, high labor intensity, low work efficiency, high risk of damage to projectiles, and high testing costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A receiving device for calibrating the velocity of a projectile in a pedestrian protection test, wherein the projectile includes an angled emission model and a horizontal emission model, and the receiving device comprises:

[0007] A frame, on which a movable component is mounted, the movable component being used to move the frame;

[0008] A first receiving component, mounted on the chassis, is used to receive angle-emitted models;

[0009] The second receiving component, mounted on the chassis, is used to receive horizontally transmitted models;

[0010] An angle adjustment component is mounted on the frame and connected to a first receiving component. The angle adjustment component is used to adjust the receiving angle of the first receiving component.

[0011] Based on the above-mentioned technical means, the first receiving component and the second receiving component respectively capture the angled launch model and the horizontal launch model. At the same time, the receiving angle of the first receiving component can be flexibly adjusted by the angle adjustment component to adapt to the needs of different collision simulation scenarios. The overall position can be easily adjusted by the moving component on the frame. It has high practicality, wide applicability, good compatibility, high recovery efficiency and convenience. It avoids the risk of the launched object falling directly to the ground and colliding with hard objects on the ground and being damaged, reduces the testing cost and solves the problems of cumbersome launch object recovery and high manual labor intensity.

[0012] Furthermore, the first receiving component includes a first receiving box, which is mounted on the frame. A first feed port is formed at the top of the first receiving box, and the angled emission model is configured to pass through the first feed port into the first receiving box.

[0013] Based on the above technical means, the first receiving box is securely installed on the vehicle frame, and its top is designed with a first feeding port to ensure that the angled launch model can accurately pass through the first feeding port into the first receiving box, realizing efficient and safe reception of the angled launch model, and further improving the convenience and testing efficiency of the launch object recovery in pedestrian protection tests.

[0014] Furthermore, the first receiving component also includes a first buffer pad, which covers the inner wall of the first receiving box.

[0015] Based on the above technical means, a first buffer pad was added to the inner wall of the first receiving box, which reduced the impact force generated when the angled launch model collided with the first receiving box at high speed. This effectively prevented the angled launch model from being damaged due to collision with the first receiving box, reduced testing costs, ensured the integrity of the angled launch model, and thus further ensured the accuracy and consistency of the test results.

[0016] Furthermore, the second receiving component includes a second receiving box mounted on the frame, a second inlet formed on one side of the second receiving box, the first receiving box located on the other side of the second receiving box, and the horizontally emitting model configured to enter the second receiving box through the second inlet.

[0017] Based on the aforementioned technical means, a second inlet is provided on one side of the second receiving box, allowing the horizontally launched model to smoothly pass through the second inlet and enter the second receiving box. The first receiving box is located on the other side of the second receiving box, resulting in a compact layout that facilitates movement and storage. This achieves efficient and safe reception of the horizontally launched model, further improving the convenience and testing efficiency of the launch object recovery in pedestrian protection tests. Moreover, through reasonable space planning, interference between the first and second receiving components is avoided, further enhancing the smoothness and efficiency of the launch object recovery in pedestrian protection tests.

[0018] Furthermore, the second receiving component also includes a second cushioning pad, which covers the inner wall of the second receiving box.

[0019] Based on the above technical means, a second buffer pad was added to the inner wall of the second receiving box, which reduced the impact force generated when the horizontal launch model collided with the second receiving box at high speed. This effectively prevented the horizontal launch model from being damaged due to collision with the second receiving box, reduced the testing cost, ensured the integrity of the horizontal launch model, and thus further ensured the accuracy and consistency of the test results.

[0020] Furthermore, the bottom plate, top plate, and side walls of the second receiving box are all made of protective netting.

[0021] Based on the aforementioned technical means, using a protective net as the bottom plate, top plate, and side wall of the second receiving box not only further reduces the impact force between the horizontal launch model and the second receiving box, ensuring the integrity of the horizontal launch model, but also allows staff to clearly see the entry and dwell status of the launch object, facilitating real-time monitoring and recording of test results. In addition, while ensuring sufficient strength and durability, the protective net also reduces the overall weight of the second receiving box, making it easier to transport and install, further improving the practicality and flexibility of the launch object receiving device in pedestrian protection tests.

[0022] Furthermore, the angle adjustment assembly includes a base support rod, two horizontal support rods, and two vertical support rods. The base support rod is mounted on the frame and abuts against the bottom of the first receiving box. The two horizontal support rods are arranged in parallel, with one end of each horizontal support rod mounted on one side of the second receiving box and the other end connected to the top of one of the vertical support rods. The bottom ends of both vertical support rods are fixed to the frame. A first adjusting horizontal rod is slidably mounted between the two horizontal support rods, and a second adjusting horizontal rod is slidably mounted between the two vertical support rods. The first adjusting horizontal rod, the second adjusting horizontal rod, and the base support rod are arranged in parallel, and the first adjusting horizontal rod and the second adjusting horizontal rod abut against the side wall of the first receiving box.

[0023] Based on the aforementioned technical means, the support base is securely installed on the vehicle frame, providing bottom support for the first receiving box. Two support crossbars are arranged in parallel, with one end connected to the side of the second receiving box and the other end fixed to the vehicle frame via a support vertical bar, forming a stable triangular support structure. This further enhances the overall structural stability. Furthermore, the first and second adjustment crossbars can slide between the two support crossbars and the two support vertical bars, respectively. Combined with the support base, by adjusting the positions of the first and second adjustment crossbars, the receiving angle of the first receiving box can be flexibly adjusted. This ensures that the first receiving box can stably receive the emitted model at different angles, improving the adaptability and adjustment accuracy of the first receiving box, and providing a more flexible and reliable projectile receiving solution for pedestrian protection experiments.

[0024] Furthermore, each of the two supporting crossbars has a first sliding groove formed along its length direction, and the two ends of the first adjusting crossbar are slidably installed in adjacent first sliding grooves respectively. Each of the two supporting vertical bars has a second sliding groove formed along its length direction, and the two ends of the second adjusting crossbar are slidably installed in adjacent second sliding grooves respectively.

[0025] Based on the aforementioned technical means, each of the two supporting crossbars is designed with a first sliding groove along its length. The two ends of the first adjusting crossbar can slide freely within these two first sliding grooves, thereby achieving horizontal position adjustment. The two supporting vertical bars are also provided with a second sliding groove along their length, and the two ends of the second adjusting crossbar slide within these two second sliding grooves, thereby achieving vertical position adjustment. This method offers good stability and high flexibility, allowing the receiving angle of the first receiving box to be precisely adjusted according to actual needs, further enhancing the adaptability and practicality of the projectile receiving device in pedestrian protection tests.

[0026] Furthermore, the moving component includes four or more rollers, each of which is symmetrically mounted on the frame.

[0027] Based on the aforementioned technical means, four or more rollers are symmetrically installed on the frame, ensuring the stability and balance of the whole during movement. This allows operators to easily push or drag the device for quick position adjustments, making the movement and positioning of the receiving device more convenient and providing strong support for the smooth progress of the test.

[0028] Furthermore, the angular emission model is a spherical model, and the horizontal emission model is a cylindrical model.

[0029] Based on the aforementioned technical means, the angled launch model is a spherical model to simulate the trajectory and force of spherical objects such as pedestrian heads in real collisions, while the horizontal launch model adopts a cylindrical model to better simulate the performance of columnar objects such as pedestrian legs in collisions.

[0030] The beneficial effects achieved by this utility model are:

[0031] 1. This utility model captures the angular launch model and the horizontal launch model respectively through the first receiving component and the second receiving component, and easily achieves the overall position adjustment through the moving component on the frame. It has good compatibility, high recovery efficiency and convenience. It avoids the risk of the launch object falling directly to the ground and being damaged by collision with hard objects on the ground, reduces the testing cost and solves the problems of cumbersome launch object recovery and high manual labor intensity.

[0032] 2. This utility model flexibly adjusts the receiving angle of the first receiving component through the angle adjustment component to adapt to the needs of different collision simulation scenarios, and has high practicality and wide applicability. Attached Figure Description

[0046] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0047] This embodiment relates to a receiving device for calibrating the velocity of a projectile in a pedestrian protection test, such as... Figure 1 As shown, a receiving device for calibrating the velocity of a projectile in a pedestrian protection test is disclosed. The projectile includes an angled projectile model 01 and a horizontal projectile model 02. The receiving device includes: a frame 1, on which a moving component 2 is mounted, which is used to move the frame 1; a first receiving component 3, which is mounted on the frame 1 and is used to receive the angled projectile model 01; a second receiving component 4, which is mounted on the frame 1 and is used to receive the horizontal projectile model 02; and an angle adjustment component 5, which is mounted on the frame 1 and connected to the first receiving component 3, and is used to adjust the receiving angle of the first receiving component 3.

[0048] In practical application, the angular launch model 01 is a spherical model, employing a parabolic trajectory during launch velocity calibration to simulate a pedestrian's head impact. The horizontal launch model 02 is a cylindrical model, using a horizontal trajectory during launch velocity calibration to simulate a pedestrian's leg impact. Furthermore, as a preferred embodiment, the moving component 2 consists of four rollers, symmetrically mounted on the frame 1. The number of rollers can also be four or more to improve the stability of the frame 1. Specifically, after the spherical model launches, the frame 1 is moved via the rollers, allowing the first receiver to... Component 3 is located at the drop position of the spherical model. Based on the actual flight angle, the angle adjustment component 5 precisely adjusts the receiving angle of the first receiving component 3, allowing the freely flying spherical model to fall into the first receiving component 3. After the cylindrical model is launched, the frame 1 is moved by the rollers, so that the second receiving component 4 is located at the drop position of the cylindrical model, allowing the freely flying cylindrical model to fall into the second receiving component 4. This design has a wide range of applications, ensures the accuracy of the test, improves the testing efficiency, reduces the risk of damage to the projectile, and provides reliable support for the research and development of pedestrian protection technology.

[0049] In this embodiment, the first receiving component 3 includes a first receiving box 31, which is mounted on the frame 1. A first feed port 311 is formed at the top of the first receiving box 31. The angled emission model 01 is configured to pass through the first feed port 311 and enter the first receiving box 31.

[0050] This implementation example Figure 2 and Figure 5 As shown, the first receiving box 31 is securely installed on the frame 1, realizing efficient and safe reception of the angle-launched model 01, further improving the convenience and testing efficiency of the launch object recovery in pedestrian protection tests. In actual application, after the spherical model is launched, the frame 1 is moved by each roller so that the first receiving box 31 is located at the falling position of the spherical model. According to the actual flight angle, the angle adjustment component 5 is used to precisely adjust the angle of the first feed port 311 so that the freely flying spherical model can pass through the first feed port 311 and enter the first receiving box 31.

[0051] Furthermore, in a preferred embodiment, the first receiving component 3 further includes a first buffer pad 32, which covers the inner wall of the first receiving box 31; as shown Figure 5 As shown, in this embodiment, a first buffer pad 32 is added to the inner wall of the first receiving box 31, which reduces the impact force generated when the angled launch model 01 hits the first receiving box 31 at high speed, reduces the risk of damage to the angled launch model 01 and the first receiving box 31, reduces the testing cost, and ensures the integrity of the angled launch model, thereby further ensuring the accuracy and consistency of the test results.

[0052] In this embodiment, the second receiving component 4 includes a second receiving box 41, which is mounted on the frame 1. A second inlet 411 is formed on one side of the second receiving box 41, and a first receiving box 31 is located on the other side of the second receiving box 41. The horizontally emitting model 02 is configured to enter the second receiving box 41 through the second inlet 411.

[0053] This implementation example Figure 1 , Figure 2 and Figure 4 As shown, the second receiving box 41 is securely mounted on the frame 1, enabling efficient and safe reception of the horizontally launched model 02. This further improves the convenience and testing efficiency of the launch object recovery in pedestrian protection tests. Moreover, through reasonable space planning and compact layout, interference between the first receiving box 31 and the second receiving box 41 is avoided, further improving the smoothness and efficiency of the launch object recovery in pedestrian protection tests. In practical applications, after the cylindrical model is launched, the frame 1 is moved by the rollers so that the second receiving box 41 is located at the fall position of the cylindrical model, allowing the freely flying cylindrical model to pass through the second feed port 411 and enter the second receiving box 41.

[0054] Furthermore, in a preferred embodiment, the second receiving component 4 further includes a second buffer pad 42, which covers the inner wall of the second receiving box 41; as shown Figure 1 As shown, in this embodiment, a second buffer pad 42 is added to the inner wall of the second receiving box 41, which reduces the impact force generated when the horizontal launch model 02 hits the second receiving box 42 at high speed, reduces the risk of damage to the horizontal launch model 02 from the collision with the second receiving box 42, reduces the test cost, and ensures the integrity of the horizontal launch model 02, thereby further ensuring the accuracy and consistency of the test results.

[0055] Furthermore, as a preferred embodiment, the bottom plate, top plate, and side walls of the second receiving box 41 are all made of protective netting 412; such as Figure 1 and Figure 2 As shown, the use of protective netting 412 as the bottom plate, top plate, and side wall of the second receiving box 41 not only further reduces the impact force between the horizontal launching model 02 and the second receiving box 41, ensuring the integrity of the horizontal launching model 02, but also allows the staff to clearly see the entry and exit status of the cylindrical model, facilitating real-time monitoring and recording of test results. In addition, while ensuring sufficient strength and durability, the protective netting 4112 also reduces the overall weight of the second receiving box 41, making it easier to transport and install, further improving the practicality and flexibility of the launching receiving device in pedestrian protection tests.

[0056] In this embodiment, the angle adjustment assembly 5 includes a supporting base rod 51, two supporting cross rods 52, and two supporting vertical rods 53. The supporting base rod 51 is mounted on the frame 1 and can abut against the bottom end of the first receiving box 31. The two supporting cross rods 52 are arranged in parallel. One end of each of the two supporting cross rods 52 is mounted on one side of the second receiving box 41, and the other end is connected to the top end of one of the supporting vertical rods 53. The bottom ends of both supporting vertical rods 53 are fixed on the frame 1. A first adjusting cross rod 54 is slidably installed between the two supporting cross rods 52, and a second adjusting cross rod 55 is slidably installed between the two supporting vertical rods 53. The first adjusting cross rod 54, the second adjusting cross rod 55, and the supporting base rod 51 are arranged in parallel to each other, and the first adjusting cross rod 54 and the second adjusting cross rod 55 can abut against the side wall of the first receiving box 31.

[0057] This implementation example Figure 3 As shown, the support base rod 51 is firmly installed on the frame 1, providing bottom support for the first receiving box 31. The two support crossbars and the support vertical rod form a stable triangular support structure with the frame and the first receiving box 31, further enhancing the stability of the overall structure. Specifically, in practical applications, the bottom centerline of the first receiving box 31 is located on the support base rod 51. The first receiving box 31 is clamped between the first adjusting crossbar 54 and the second adjusting crossbar 55. According to the actual drop angle of the spherical model, the horizontal and vertical positions of the first adjusting crossbar 54 and the second adjusting crossbar 55 are slid respectively, so that the first receiving box 31 can rotate along the support base rod 51 to adjust the angle of the second feed port 411, which facilitates accurate reception of the spherical model. It is highly flexible and improves the adaptability and adjustment accuracy of the first receiving box 41, providing a more flexible and reliable projectile receiving solution for pedestrian protection tests.

[0058] Furthermore, in a preferred embodiment, each of the two supporting crossbars 52 has a first sliding groove 521 formed along its length direction, and the two ends of the first adjusting crossbar 54 are slidably installed in adjacent first sliding grooves 521 respectively; each of the two supporting vertical bars 53 has a second sliding groove 531 formed along its length direction, and the two ends of the second adjusting crossbar 55 are slidably installed in adjacent second sliding grooves 531 respectively; Figure 3As shown, in practical application, both support crossbars 52 are designed with first sliding grooves 521 along their length. The two ends of the first adjusting crossbar 54 can slide freely in these two first sliding grooves 521, thereby realizing horizontal position adjustment. The two support vertical bars 53 are also provided with second sliding grooves 531 along their length. The two ends of the second adjusting crossbar 55 slide in these two second sliding grooves 531, thereby realizing vertical position adjustment. It has good stability and high flexibility, so that the receiving angle of the first receiving box 41 can be precisely adjusted according to actual needs, further improving the adaptability and practicality of the projectile receiving device in pedestrian protection tests.
