Description

Technical Field

[0001] This utility model relates to the technical field of vehicle testing devices, specifically to a passenger vehicle lateral rollover testing device. Background Technology

[0002] With the continuous development of the automotive industry, vehicle safety performance is receiving increasing attention. Among numerous safety performance tests, vehicle rollover tests are a crucial step in evaluating vehicle stability and passenger safety under extreme conditions. In particular, passenger car side rollover tests can simulate scenarios where vehicles roll over under conditions such as side collisions and loss of control, providing important data for vehicle structural design and safety system optimization. Passenger car rollover devices are engineering devices designed to address real-world accident test scenarios such as vehicle rollover caused by side collisions or rollovers on steep slopes due to vehicles running off the road.

[0003] However, traditional experimental setups mostly use a single tilt adjustment mechanism to change the angle of the test platform, which can only adjust the tilt angle of the tilting platform to simulate basic rollover conditions. In real life, vehicle rollover accidents have complex and diverse characteristics, and traditional experimental setups cannot reproduce the complex rollover postures of vehicle rollover accidents through a single tilt adjustment mechanism, such as the superposition of lateral and pitch movements, or the multi-directional contact between the vehicle body and the ground during spiral rollover. Summary of the Invention

[0004] The purpose of this invention is to provide a passenger vehicle side rollover test device, which aims to solve the problem of low flexibility in the prior art.

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

[0006] A passenger vehicle side rollover test apparatus, comprising:

[0007] A slide rail assembly and a base, wherein one end of the slide rail assembly is rotatably mounted on the base to allow the slide rail assembly to have an inclined angle; the slide rail assembly is used to mount a test vehicle, the test vehicle being able to slide on the slide rail assembly along its length.

[0008] An angle adjustment component is movably supported between the slide rail assembly and the base, and the angle adjustment component is used to adjust the tilt angle of the slide rail assembly;

[0009] Multiple height adjustment components are provided, each of which is used to fix and support the base, and each of the height adjustment components can extend and retract along the height direction to adjust the height and tilt angle of the base.

[0010] According to the above-mentioned technical means, each height adjustment component can extend and retract along the height direction, and can adjust the tilt angle of the base. At the same time, the tilt angle of the base can be adjusted by the angle adjustment component, which can also adjust the tilt angle of the slide rail component. The angle adjustment component forms a two-level adjustment between the slide rail and the base. The two combined can produce a compound tilt angle, which significantly expands the test coverage scenario. At the same time, it can reproduce the complex rollover posture of vehicle rollover accidents. This versatility makes the test device not only suitable for the side rollover test of passenger cars, but also suitable for other types of vehicle rollover tests, such as roof rollover tests, by adjusting the parameters, thus improving the versatility and flexibility of the test device.

[0011] Furthermore, it also includes a connecting component slidably mounted on the slide rail assembly, wherein the test vehicle is placed on the connecting component so that the test vehicle is slidably mounted on the slide rail assembly via the connecting component.

[0012] According to the aforementioned technical means, the connecting component is slidably mounted on the slide rail assembly. The test vehicle is placed on the connecting component, and its two ends are connected to the slide rail assembly and the vehicle, respectively. This allows the test vehicle to be mounted more stably on the slide rail assembly, avoiding potential shaking or instability that might occur when the vehicle slides on the slide rail due to direct contact. As an intermediate connecting component, the connecting component can better adapt to the shape and size of the vehicle, ensuring the stability and safety of the vehicle during testing.

[0013] Furthermore, the connecting assembly includes rollers and a connecting frame, the rollers being mounted on the connecting frame and movably mounted on the slide rail assembly so that the connecting frame can move on the slide rail assembly; the connecting frame is used to mount the test vehicle.

[0014] Based on the aforementioned technical means, the frictional resistance between the connecting component and the slide rail component is reduced by incorporating rollers. Compared to a direct sliding connection, the rolling friction coefficient of the rollers is much lower, allowing the test vehicle to slide more smoothly along the slide rail component. This reduces energy loss and speed changes caused by friction, enabling a more realistic simulation of the vehicle's motion in actual rollover scenarios and improving the accuracy and reliability of the test results. The connecting frame, as the intermediate component connecting the vehicle and the rollers, provides stable support and connection, and increases the overall rigidity and stability of the connecting component, reducing potential shaking or deformation during the test and ensuring a smooth testing process.

[0015] Furthermore, the connecting frame includes a frame body for placing the test vehicle. The frame body is adjustable in length along the slide rail assembly to accommodate the width of different types of test vehicles.

[0016] Based on the aforementioned technical means, the frame body can be extended and retracted along the length of the slide rail assembly, allowing the connecting frame to adapt to test vehicles of different widths. In actual tests, the body widths of different vehicle models vary considerably. Through the adjustment function of the telescopic frame body, the width of the connecting frame can be easily adjusted to meet the installation requirements of various vehicle models, increasing the flexibility of the connecting frame.

[0017] Furthermore, the connecting assembly also includes a hook, which is mounted on the connecting frame; a release mechanism is provided on the other end of the slide rail assembly, which can be connected to or disconnected from the hook to fix or release the hook.

[0018] Based on the aforementioned technical means, the design of the hook and release mechanism allows the vehicle to be securely fixed before the test. During the test preparation stage, the vehicle is firmly fixed to the slide rail assembly by the hook, avoiding potential safety accidents caused by accidental sliding of the vehicle and improving the safety of the test process. Especially during high-risk tests, it can effectively prevent the vehicle from going out of control and protect the safety of test personnel and equipment. During the test, the release mechanism can precisely release the hook, allowing the vehicle to begin sliding according to the predetermined initial conditions, thereby improving the accuracy and reliability of the test results.

[0019] Furthermore, the angle adjustment component includes a first adjustment member, one end of which is hinged to the slide rail assembly, and the other end of which is movably mounted on the base, so that the first adjustment member can adjust its own height by moving, thereby adjusting the tilt angle of the slide rail assembly.

[0020] Based on the aforementioned technical means, the first adjusting component can adjust its own height by moving, thereby adjusting the tilt angle of the slide rail assembly, which improves the flexibility and adaptability of the experimental device. Test personnel can quickly adjust the tilt angle of the slide rail assembly according to the center of gravity height, body size, and test requirements of different vehicle models. The experimental device can meet the needs of more vehicle models and test scenarios. The first adjusting component is connected to the slide rail assembly and the base by hinge and movement, which can accurately adjust the tilt angle of the slide rail assembly and ensure the stability of the device during the test. The force generated when the vehicle slides along the slide rail assembly will be transmitted to the base through the first adjusting component, thereby ensuring the stability of the entire device.

[0021] Furthermore, the first adjusting component includes a slide rod and a support rod. The base forms a limiting groove, which is distributed along the length direction of the base. The slide rod is slidably installed in the limiting groove and can move within the limiting groove. One end of the support rod is hinged to the slide rail assembly, and the other end is fixedly connected to the slide rod. The support rod can slide on the limiting groove via the slide rod to adjust its own height.

[0022] Based on the aforementioned technical means, the design of the limiting groove provides a clear movement path for the limiting slide rod, avoiding possible offset or wobbling during the adjustment process, improving the stability and reliability of the adjustment process, ensuring that the tilt angle of the slide rail assembly can be precisely and stably controlled, reducing test errors caused by inaccurate or unstable angle adjustment, and improving the reliability of test results. The design of the limiting slide rod and support rod enables precise control of the tilt angle of the slide rail assembly, reducing test risks caused by improper angle adjustment. At the same time, the design of the limiting groove also prevents the limiting slide rod from accidentally slipping off during the adjustment process, further enhancing the safety of the experimental device.

[0023] Furthermore, the angle adjustment assembly also includes a second adjustment member, one end of which is fixedly connected to the slide rod, and the other end is hinged to the slide rail assembly. The second adjustment member is configured to extend and retract along the length direction, thereby adjusting the tilt angle of the slide rail assembly.

[0024] Based on the above technical means, the second adjustment component is connected to the slide rail assembly and slide rod by means of hinge and telescopic connection. This not only allows for precise adjustment of the tilt angle of the slide rail assembly, but also ensures the stability of the device during the test. The force generated when the vehicle slides along the slide rail assembly is transmitted to the base through the second adjustment component, thereby ensuring the stability of the entire device, improving the safety of the test process, and reducing the risk of test accidents caused by device instability.

[0025] Furthermore, the angle adjustment assembly includes a third adjustment member, the two ends of which are respectively hinged to the slide rail assembly and the base. The third adjustment member can be folded or extended along the height direction of the third adjustment member to adjust the tilt angle of the slide rail assembly.

[0026] According to the above technical means, the third adjustment component is connected to the slide rail assembly and the base by means of hinge and telescopic connection. It can not only accurately adjust the tilt angle of the slide rail assembly, but also ensure the stability of the device during the test. The force generated when the vehicle slides along the slide rail assembly will be transmitted to the base through the third adjustment component, thereby ensuring the stability of the entire device, improving the safety of the test process, and reducing the risk of test accidents caused by device instability.

[0027] Furthermore, the angle adjustment assembly also includes a locking member, which is mounted on the third adjustment member and can lock the third adjustment member to lock the height of the third adjustment member (33).

[0028] According to the above technical means, the locking component is installed on the third adjusting component, which can lock the third adjusting component after it is adjusted to a specific position. This ensures that the third adjusting component can be firmly locked after it is adjusted to the required position, preventing angle changes caused by external forces or vibrations, improving the stability of the experimental device during the test, and ensuring that the tilt angle of the slide rail assembly remains unchanged.

[0029] The beneficial effects of this utility model are:

[0030] 1. Each height adjustment component can extend and retract along the height direction, adjusting the tilt angle of the base. Simultaneously, the tilt angle of the base can be adjusted via an angle adjustment component, which in turn adjusts the tilt angle of the slide rail component. This angle adjustment component creates a two-stage adjustment between the slide rail and the base; the combined effect of these two adjustments produces a composite tilt angle, significantly expanding the test coverage scenarios. It can simulate various scenarios from slight side tilt to severe rollover. This versatility makes the experimental device suitable not only for lateral rollover tests of passenger vehicles but also for other types of vehicle rollover tests, such as roof rollover tests, by adjusting parameters, thus improving the versatility and flexibility of the experimental device.

[0039] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0040] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0041] like Figure 1 As shown, this embodiment proposes a passenger vehicle lateral rollover test device, including: a slide rail assembly 1 and a base 2, one end of the slide rail assembly 1 is rotatably mounted on the base 2 so that the slide rail assembly 1 has an inclination angle; the slide rail assembly 1 is used to mount a test vehicle, and the test vehicle can slide on the slide rail assembly 1 along the length direction of the slide rail assembly 1; an angle adjustment assembly 3 is movably supported between the slide rail assembly 1 and the base 2, and the angle adjustment assembly 3 is used to adjust the inclination angle of the slide rail assembly 1; and multiple height adjustment assemblies 4, each height adjustment assembly 4 is used to fix and support the base 2, and each height adjustment assembly 4 can extend and retract along the height direction to adjust the height and inclination angle of the base 2.

[0042] like Figure 1 As shown, the usage process of this embodiment is as follows: First, each height adjustment component 4 is installed on the ground, then the base 2 is installed on each height adjustment component, and finally the slide rail assembly 1 is installed on the angle adjustment component 3. During use, the tilt angle of the base 2 is adjusted by adjusting the extension height of each angle adjustment component 3. When the tilt angle of the base 2 reaches the preset angle, the adjustment of the extension height of each angle adjustment component 3 is stopped. Then, the angle adjustment component 3 is adjusted when the base 2 reaches the preset angle to adjust the tilt angle of the slide rail assembly 1. During the test, the test vehicle will experience lateral tilting due to the tilt angle of the base 2 and pitching due to the tilt angle of the slide rail assembly 1, thus presenting a complex flipping posture with the superposition of lateral tilting and pitching movements.

[0043] The angle adjustment component 3 first adjusts the slide rail assembly 1 to the preset tilt angle, and each height adjustment component 4 adjusts the base 2 to the preset angle and height. Then, the test vehicle is placed on the slide rail assembly 1, so that the test vehicle can slide along the slide rail assembly 1 and finally collide with the ground.

[0044] Each height adjustment component 4 can extend and retract along the height direction to adjust the tilt angle of the base 2. At the same time, while adjusting the tilt angle of the base 2, the tilt angle of the slide rail component 1 can be adjusted by the angle adjustment component 3. The angle adjustment component 3 forms a two-level adjustment between the slide rail 1 and the base 2. The two combined can produce a compound tilt angle, which significantly expands the test coverage scenario and can simulate various scenarios from slight tilt to severe rollover. This versatility makes the test device not only suitable for the lateral rollover test of passenger cars, but can also be used for rollover tests of other types of vehicles by adjusting the parameters, thus improving the versatility and flexibility of the test device.

[0045] In this embodiment, one end of the slide rail assembly 1 is rotatably connected to the base 2. At the same time, the tilt angle of the slide rail assembly 1 and the height of the base 2 are adjusted by the angle adjustment assembly 3 and multiple height adjustment assemblies 4. This allows the experimental device to flexibly adjust the tilt angle of the slide rail assembly 1 and the height of the base 2, thereby adapting to different vehicle models and test requirements. For passenger vehicles with different center of gravity heights or different vehicle body sizes, the tilt angle of the slide rail assembly 1 and the height of the base 2 can be adjusted to simulate a rollover scenario that is closer to the actual working conditions, thereby improving the accuracy and applicability of the test.

[0046] In this preferred embodiment, each height adjustment component 4 is a telescopic rod.

[0047] like Figure 1 and Figure 2 As shown, this embodiment also includes a connecting component 5, which is slidably mounted on the slide rail assembly 1. The test vehicle is placed on the connecting component 5 so that the test vehicle is slidably mounted on the slide rail assembly 1 via the connecting component 5.

[0048] The connecting component 5 is slidably mounted on the slide rail assembly 1. The test vehicle is placed on the connecting component 5, and its two ends are connected to the slide rail assembly 1 and the vehicle, respectively. This allows the test vehicle to be mounted more stably on the slide rail assembly 1, avoiding potential shaking or instability that might occur when the vehicle slides on the slide rail due to direct contact with it. As an intermediate connecting component, the connecting component 5 can better adapt to the shape and size of the vehicle, ensuring the stability and safety of the vehicle during testing.

[0049] like Figure 2As shown, in this embodiment, the connecting component 5 includes a roller 51 and a connecting frame 52. The roller 51 is mounted on the connecting frame 52 and is movably mounted on the slide rail assembly 1 so that the connecting frame 52 can move on the slide rail assembly 1; the connecting frame 52 is used to mount the test vehicle.

[0050] By incorporating rollers 51, the frictional resistance between the connecting assembly 5 and the slide rail assembly 1 is reduced. Compared to a direct sliding connection, the rolling friction coefficient of rollers 51 is much smaller, allowing the test vehicle to slide more smoothly along the slide rail assembly 1. This reduces energy loss and speed changes caused by friction, enabling a more realistic simulation of the vehicle's motion in actual rollover scenarios and improving the accuracy and reliability of the test results. The connecting frame 52, as an intermediate component connecting the vehicle and rollers 51, provides stable support and connection, and increases the overall rigidity and stability of the connecting assembly 5, reducing potential shaking or deformation during the test and ensuring a smooth testing process.

[0051] like Figure 2 As shown, in this embodiment, the connecting frame 52 includes a frame body 521, which is used to place the test vehicle. The frame body 521 can be extended and retracted along the length of the slide rail assembly 1 to adapt to the width of different types of test vehicles. The ability of the frame body 521 to extend and retract along the length of the slide rail assembly 1 allows the connecting frame 52 to adapt to test vehicles of different widths. In actual testing, the body widths of different vehicle models vary significantly. The adjustment function of the telescopic frame body 521 allows for easy adjustment of the width of the connecting frame 52 to meet the installation requirements of various vehicle models, increasing the flexibility of the connecting frame 52.

[0052] In this preferred embodiment, the frame body 521 includes diagonal braces, which can increase the device stability of the frame body 521.

[0053] like Figure 1 and Figure 2 As shown, in this embodiment, the connecting component 5 also includes a hook 53, which is mounted on the connecting frame 52; a release mechanism 11 is provided on the other end of the slide rail component 1, which can be connected to or disconnected from the hook 53 to fix or release the hook 53.

[0054] The design of the hook 53 and the release mechanism 11 allows the vehicle to be securely fixed before the test. During the test preparation stage, the vehicle is firmly fixed to the slide rail assembly 1 by the hook 53, avoiding safety accidents that may be caused by accidental sliding of the vehicle and improving the safety of the test process. Especially when conducting high-risk tests, it can effectively prevent the vehicle from going out of control and protect the safety of test personnel and equipment. During the test, the release mechanism 11 can precisely release the hook 53, allowing the vehicle to start sliding according to the predetermined initial conditions, thereby improving the accuracy and reliability of the test results.

[0055] like Figure 1 As shown, in this embodiment, the angle adjustment component 3 includes a first adjustment member 31. One end of the first adjustment member 31 is hinged to the slide rail assembly 1, and the other end of the first adjustment member 31 is movably mounted on the base 2 so that the first adjustment member 31 can adjust its own height by moving, thereby adjusting the tilt angle of the slide rail assembly 1.

[0056] The first adjusting component 31 can adjust its own height by moving, thereby adjusting the tilt angle of the slide rail assembly 1, which improves the flexibility and adaptability of the experimental device. Test personnel can quickly adjust the tilt angle of the slide rail assembly 1 according to the center of gravity height, body size and test requirements of different vehicle models. The experimental device can meet the needs of more vehicle models and test scenarios. The first adjusting component 31 is connected to the slide rail assembly 1 and the base 2 by hinge and movement, which can accurately adjust the tilt angle of the slide rail assembly 1 and ensure the stability of the device during the test. The force generated when the vehicle slides along the slide rail assembly 1 will be transmitted to the base 2 through the first adjusting component 31, thereby ensuring the stability of the entire device.

[0057] like Figure 3 As shown, in this embodiment, the first adjusting member 31 includes a slide rod 311 and a support rod 312. The base 2 forms a limiting groove 21, which is distributed along the length direction of the base 2. The slide rod 311 is slidably installed in the limiting groove 21 and can move within the limiting groove 21. One end of the support rod 312 is hinged to the slide rail assembly 1, and the other end is fixedly connected to the slide rod 311. The support rod 312 can slide on the limiting groove 21 through the slide rod 311 to adjust its own height.

[0058] The design of the limiting groove 21 provides a clear movement path for the limiting slide rod 311, avoiding possible offset or shaking of the slide rod 311 during the adjustment process, improving the stability and reliability of the adjustment process, ensuring that the tilt angle of the slide rail assembly 1 can be precisely and stably controlled, reducing test errors caused by inaccurate or unstable angle adjustment, and improving the reliability of test results. The design of the limiting slide rod 311 and the support rod 312 enables the tilt angle of the slide rail assembly 1 to be precisely controlled, reducing the test risk caused by improper angle adjustment. At the same time, the design of the limiting groove 21 can also prevent the limiting slide rod 311 from accidentally slipping off during the adjustment process. In this embodiment, the safety of the experimental device is enhanced.

[0059] like Figure 1 and Figure 3 As shown, in this embodiment, the angle adjustment component 3 further includes a second adjustment member 32. One end of the second adjustment member 32 is fixedly connected to the slide rod 311, and the other end is hinged to the slide rail assembly 1. The second adjustment member 32 is configured to extend and retract along the length direction, thereby adjusting the tilt angle of the slide rail assembly 1.

[0060] The second adjusting member 32 is connected to the slide rail assembly 1 and the slide rod 311 by means of hinge and telescopic connection. It can not only accurately adjust the tilt angle of the slide rail assembly 1, but also ensure the stability of the device during the test. The force generated when the vehicle slides along the slide rail assembly 1 will be transmitted to the base 2 through the second adjusting member 32, thereby ensuring the stability of the entire device, improving the safety of the test process, and reducing the risk of test accidents caused by device instability.

[0061] like Figure 1 As shown, in this embodiment, the angle adjustment component 3 includes a third adjustment member 33. The two ends of the third adjustment member 33 are respectively hinged to the slide rail assembly 1 and the base 2. The third adjustment member 33 can be folded or extended along the height direction of the third adjustment member 33 to adjust the tilt angle of the slide rail assembly 1.

[0062] The third adjusting member 33 is connected to the slide rail assembly 1 and the base 2 by means of hinge and telescoping. It can not only accurately adjust the tilt angle of the slide rail assembly 1, but also ensure the stability of the device during the test. The force generated when the vehicle slides along the slide rail assembly 1 will be transmitted to the base 2 through the third adjusting member 33, thereby ensuring the stability of the entire device, improving the safety of the test process, and reducing the risk of test accidents caused by device instability.

[0063] like Figure 1As shown, in this embodiment, the angle adjustment assembly 3 further includes a locking member 34, which is mounted on the third adjustment member 33. The locking member 34 can lock the third adjustment member 33 to lock its height. The locking member, mounted on the third adjustment member 33, can lock the third adjustment member 33 after it has been adjusted to a specific position, ensuring that the third adjustment member 33 is securely locked after being adjusted to the desired position. This prevents angle changes caused by external forces or vibrations, improves the stability of the experimental device during the test, and ensures that the tilt angle of the slide rail assembly 1 remains unchanged.
