Description

Technical Field

[0001] This utility model relates to the technical field of automotive safety testing devices, and in particular to a vehicle pedestrian protection test marking device. Background Technology

[0002] In the development of automotive products, pedestrian protection performance is an important safety evaluation indicator. According to relevant regulations, impact tests on the head, legs, and other body parts must be conducted in specific areas at the front of the vehicle. Before conducting these tests, the impact positions and angles of each test module must be precisely marked on the vehicle body; this process is called marking.

[0003] Traditional marking methods primarily rely on manual measurement and marking using conventional rulers. This process involves repeated measurements and positioning, making it cumbersome and time-consuming. Furthermore, manual measurement and marking are prone to errors and struggle to precisely control the spatial angles of the test module, directly impacting the accuracy and comparability of subsequent test results. While some marking devices exist, they struggle with marking complex areas of the vehicle body. Marking results from different operators or even the same operator at different times can vary significantly. Additionally, for complex vehicle front profiles, it is difficult to quickly and accurately determine the collision test areas for different body parts (such as an adult's head, a child's head, thighs, and calves), affecting the accuracy of the test.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a vehicle pedestrian protection test marking device to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0006] To overcome the shortcomings of the existing technology, the present invention discloses a vehicle pedestrian protection test marking device, which solves the problems of low efficiency, poor operational flexibility, large error and poor repeatability of traditional marking technology.

[0007] This utility model discloses a vehicle pedestrian protection test marking device, comprising:

[0008] The XYZ three-way motion module has a vertical cursor transmitter and an adjustable-angle rotating arm connected to its execution end. The vertical cursor transmitter is located behind the rotating arm.

[0009] The actuator of the rotating arm is pluggably mounted with a test module, which includes a human head model for simulating head impact and a plate structure for simulating leg and torso impact.

[0010] Preferred technical solution: The XYZ three-way moving module includes a horizontal moving mechanism, a lifting mechanism, and a slide bar;

[0011] The lifting mechanism is installed at the actuator end of the horizontal moving mechanism;

[0012] The slide bar is slidably connected to the execution end of the lifting mechanism, and its sliding direction is perpendicular to the moving direction of the horizontal moving mechanism;

[0013] A vertical cursor emitter is fixedly mounted at the rear end of the slide bar, and a rotating arm is connected to the front end of the slide bar via a pivot with a locking function. The ray axis of the vertical cursor emitter is parallel to the axis of the slide bar, ensuring the accuracy of the light spot projection.

[0014] Preferred technical solution: The horizontal moving mechanism includes a horizontal slide rail and a moving plate slidably disposed on the horizontal slide rail. The moving plate is provided with a locking screw for locking it onto the horizontal slide rail, and a handle mechanism is provided at the upper end of the locking screw.

[0015] Preferred technical solution: The horizontal slide rail of the horizontal moving mechanism is provided with an elastic limit mechanism at the end of its stroke.

[0016] Preferred technical solution: The lifting mechanism includes a lifting frame fixedly connected to the movable plate, and a lifting platform that slides vertically along the lifting frame;

[0017] A balancer is connected between the lifting platform and the top of the lifting frame; it is used to balance the weight of the slide bar, rotating arm and test module, making the lifting operation less strenuous.

[0018] The lifting mechanism is equipped with locking bolts for securing the lifting platform to the lifting frame.

[0019] The preferred technical solution is as follows: the bottom of the horizontal moving mechanism is equipped with casters with braking mechanisms and height-adjustable feet. This enables flexible movement and stable support of the device.

[0020] Preferred technical solution: Both the horizontal slide rail of the horizontal moving mechanism and the lifting frame of the lifting mechanism are equipped with scales for marking the moving distance. This facilitates accurate positioning and reading.

[0021] Preferred technical solution: The rear end of the slide bar is equipped with a collision-resistant silicone door stop. This provides a safety buffer, preventing hard collisions with vehicles or other equipment.

[0022] A preferred technical solution includes a dedicated, independently set scribing ruler, made of soft material and available in various sizes. This ruler allows for the drawing of highly conforming reference lines on the vehicle's curved surface based on the points marked by the vertical cursor transmitter.

[0023] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0024] This invention achieves a perfect combination of non-contact optical positioning and physical testing by integrating the vertical cursor transmitter and the test module mounting arm onto the same mobile module. The cursor positioning is contactless and deviation-free, providing a precise benchmark for subsequent marking and testing, ensuring the repeatability and accuracy of test results. The XYZ three-way mobile module, combined with the scale reading, can quickly position the device to the preset coordinates. The flip-up rotating arm and pluggable test module allow the device to quickly adapt to the complex contours of different vehicle models and different types of tests (head impact, leg impact, etc.), greatly improving test preparation efficiency. The combination of bottom casters and feet ensures a balance between mobility and stability. The introduction of a balancer significantly reduces the operator's workload, while locking mechanisms in all directions ensure the rigidity of the entire system after positioning, preventing displacement during testing. Elastic limit mechanisms and anti-collision silicone door stops effectively protect the device itself and the vehicle model under test, avoiding accidental damage. Attached Figure Description

[0036] Example:

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a vehicle pedestrian protection test marking device, including an XYZ three-way moving module 1, a vertical cursor transmitter 2, a rotating arm 3, and a test module 4. The main components of this utility model will be described in detail below:

[0038] The XYZ three-way moving module 1 is used to achieve precise positioning of the device in three-dimensional space. Its bottom is equipped with casters 15 with braking mechanisms and height-adjustable feet 16 for easy movement and leveling / fixing. The XYZ three-way moving module 1 includes a horizontal moving mechanism 11, a lifting mechanism 12, and a sliding rod 13.

[0039] The horizontal moving mechanism 11 includes a horizontal slide rail 111, a moving plate 112, a locking screw 113, and a handle mechanism 114. The moving plate 112 can slide along the horizontal slide rail 111. By rotating the handle mechanism 114, the locking screw 113 is driven downward, thus pressing and fixing the moving plate 112 at any position on the horizontal slide rail 111. An elastic limiting mechanism 115 is installed at the end of the horizontal slide rail 111 to prevent overtravel.

[0040] The lifting frame 121 of the lifting mechanism 12 is fixedly connected to the moving plate 112. The lifting platform 122 can slide vertically up and down along the lifting frame 121. A balancer 123 is installed between the lifting platform 122 and the top of the lifting frame 121 to balance the weight of the subsequent components. The lifting platform 122 can be locked onto the lifting frame 121 by tightening the locking bolts 124 on the lifting mechanism. Precise scales 116 are engraved on both the horizontal slide rail 111 and the lifting frame 121 to indicate the movement distance.

[0041] The slide bar 13 is horizontally mounted on the lifting platform 122, and its sliding direction is perpendicular to the moving direction of the horizontal moving mechanism 11. The vertical cursor emitter 2 is fixedly mounted at the rear end of the slide bar 13, and its front end is connected to the rotating arm 3 through a pivot 14 with a locking function. The rear end of the slide bar 13 is also equipped with a collision-resistant silicone door stop 131. The beam direction of the vertical cursor emitter 2 is parallel to the axis of the slide bar 13 to ensure accurate geometric relationship of the beam projection.

[0042] The rotating arm 3 can rotate around the rotating shaft 14 at the desired angle, and then be fixed by the locking function of the rotating shaft 14. The actuator end of the rotating arm 3 is equipped with a quick-connect interface for pluggable installation of different test modules 4, such as a human head model or a plate structure for leg and torso impact testing.

[0043] In addition, the device is equipped with a separate dedicated scribing ruler 5, which is made of soft rubber or silicone material and comes in different sizes. It can easily fit the curved surface of the car body and is used to scribing lines according to the points marked by the cursor.

[0044] Work process:

[0045] First, fix the vehicle model to be tested on the test bench, push the device to a suitable position in front of it, lower the leveling feet 16 and lock the casters 15 to brake.

[0046] Then, the coordinates for positioning are determined according to the test specifications. All locking mechanisms are loosened, and the device is moved to the target position by manual pushing, referring to the ruler 116. Specifically, the horizontal movement mechanism 11 and the lifting mechanism 12 are positioned first, and then the sliding rod 13 is adjusted for final positioning. During positioning, the light spot emitted by the vertical cursor emitter 2 is always projected onto the vehicle body as a visual reference. After positioning, all locking mechanisms are immediately locked. The corresponding head model or panel structure is then installed on the rotating arm 3, adjusted to the standard impact angle, and locked. When the head model or panel structure contacts the vehicle body, the sliding rod 13 is locked, and a line is drawn according to the current position of the light spot from the vertical cursor emitter 2 to more accurately mark the actual collision area. The operator draws the required collision area reference line on the vehicle surface along the points marked by the light spot, either directly or using a dedicated scribing ruler 5.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
