[0028] The embodiments of the present invention 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] The upper leg type test auxiliary device 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0030] Reference Figure 1-Figure 5 According to the upper leg type test auxiliary device 100 of the embodiment of the utility model, it is used for the pedestrian protection upper leg type test. The upper leg type test auxiliary device 100 includes a device body 10, and the device body 10 includes an upper leg type rigid frame 11, a fixed bracket 20 and a laser 30. The fixed bracket 20 is movably and detachably arranged on the upper leg type rigid frame 11. The laser 30 is arranged on the fixed bracket 20, and the center of the laser beam emitted by the laser 30 is used to simulate the center of the upper leg type. Among them, in the pedestrian protection upper leg type test, the laser 30 is suitable for emitting a laser to the front end of the vehicle to assist in the determination of the test marking and the test point position.

[0031] The laser 30 is arranged on the fixed bracket 20, and the fixed bracket 20 is arranged on the upper leg type rigid frame 11 and is movable. The upper leg type rigid frame 11 is fixed on the test equipment. By adjusting the position of the fixed bracket 20 on the upper leg type rigid frame 11, the center position of the laser beam emitted by the laser 30 can be adjusted. When the center of the laser beam is adjusted to be parallel to the center line of the upper leg type rigid frame 11 and the movement direction of the test, the center of the laser beam coincides with the center of the upper leg type, so that the center of the laser beam emitted by the laser 30 can more accurately simulate the center of the upper leg type. In addition, after adjusting the center position of the laser beam, the fixed bracket 20 and the upper leg type rigid frame 11 are relatively fixed.

[0032] Optionally, when adjusting the center position of the laser beam, a three-coordinate measuring instrument can be used to ensure that the line connecting the center of the laser beam and the center of the upper leg type rigid frame 11 is parallel to the movement direction of the test, thereby ensuring that the center of the laser beam coincides with the center of the upper leg type in the movement direction of the test during the test.

[0033] The laser 30 is disposed on the fixed bracket 20, and the fixed bracket 20 is disposed on the upper leg type rigid frame 11 and is detachable, which can facilitate the assembly and disassembly of the fixed bracket 20 and the upper leg type rigid frame 11. In addition, the detachable fixed bracket 20 can facilitate the subsequent test steps of the pedestrian protection upper leg type test. For example, after the upper leg type test auxiliary device 100 completes the test auxiliary work, the fixed bracket 20 can be removed from the upper leg type rigid frame 11, and then the upper leg type foam muscle and skin are installed on the upper leg type rigid frame 11, and the impact test is performed.

[0034] Optionally, the fixing bracket 20 may be detachably connected to the upper leg-shaped rigid frame 11 via a fastener, or the fixing bracket 20 may be detachably connected to the upper leg-shaped rigid frame 11 via a magnetic member.

[0035] In the pedestrian protection upper leg test, the laser 30 emits laser light toward the front end of the vehicle. The laser beam has strong directivity, high brightness and good straightness, and can form a clear auxiliary line at the front end of the vehicle (refer to Figure 4 During the test marking process, the points can be measured and marked along the auxiliary lines formed by the laser beam, thereby improving the accuracy of the test marking and ensuring the accuracy of the test point position, thereby improving the accuracy of the pedestrian protection upper leg type test.

[0036] The center of the laser beam emitted by the laser 30 is used to simulate the center of the upper leg type, and can display the position of the center of the upper leg type in real time. The upper leg type test auxiliary device 100 is moved so that the center of the laser beam moves to coincide with the test point, so that the center of the upper leg type and the test point can be coincident, thereby facilitating point-to-point operation of the upper leg type center and the test point, thereby improving the accuracy and convenience of the pedestrian protection upper leg type test.

[0037] In addition, in the upper leg type test for pedestrian protection, the upper leg type test auxiliary device 100 can cooperate with existing test equipment, such as an upper leg type impactor, a three-coordinate measuring instrument, etc., and use the center of the laser beam to coincide with the test point to record and save the test point. At the same time, the laser beam emitted by the laser can ensure the coincidence degree between the center of the upper leg type and the test point, so that it is easy to measure the test speed when the center of the upper leg type first contacts the front of the vehicle, thereby ensuring that the upper leg type can be accelerated to the specified impact speed when it first contacts the front of the vehicle, thereby improving the accuracy and convenience of the upper leg type test for pedestrian protection.

[0038] It should be noted that in the pedestrian protection upper leg test, the center of the upper leg coincides with the test point and the outer contour of the upper leg just contacts the front of the vehicle, which is the first contact between the leg and the front of the vehicle. The position when the upper leg just contacts the front of the vehicle is the first contact position.

[0039] Optionally, the laser 30 may be disposed at the center of the fixing bracket 20 .

[0040] According to the upper leg type test auxiliary device 100 of the embodiment of the utility model, it is possible to assist in the test marking and the determination of the test points, thereby improving the accuracy of the marking and ensuring the degree of coincidence between the center of the upper leg type and the test points, thereby improving the accuracy and convenience of the pedestrian protection upper leg type test.

[0041] Refer to the following Figure 1-Figure 5 (in Figure 4 as well as Figure 5 The straight line L below the vehicle is the ground reference plane) describes the test process of the upper leg type impact WAD775 test using the upper leg type test auxiliary device 100.

[0042] First, mark and draw lines at the front end of the vehicle. Install the upper leg type test auxiliary device 100 in the test equipment, adjust the center position of the cross laser beam, and use a three-coordinate measuring instrument to ensure that the center of the cross laser beam coincides with the center of the upper leg type in the test movement direction. Move the test equipment so that the upper leg type test auxiliary device 100 is located at the front of the vehicle, and make the vertical laser beam emitted by the cross laser 30 of the upper leg type test auxiliary device 100 align with the longitudinal center line of the vehicle.

[0043] According to the regulations, use a flexible ruler to mark WAD775, WAD930 and IBRL (internal bumper reference line) along the auxiliary line S formed by the cross laser beam on the outer surface of the vehicle, and then move the test equipment in the left and right directions of the vehicle at intervals of 100mm, and use a flexible ruler to mark WAD775 (reference Figure 4 Point a), WAD930 (refer to Figure 4 b) and IBRL (refer to Figure 4 Then move the test equipment in the left and right directions of the vehicle at intervals of 100 mm, repeat the above marking operation, and the test point determination and marking operation can be completed.

[0044] In this process, the coordinates of each point are measured by a three-dimensional coordinate measuring machine, and the impact angle α of each test point is calculated according to the coordinates of WAD930 and IBRL (refer to Figure 5 The impact angle α) is taken as the impact angle, and the specified impact speed is calculated according to the impact angle and the calculation formula when the center of the upper leg coincides with the test point and the outer contour of the upper leg makes first contact with the vehicle.

[0045] Secondly, adjust the impact angle and impact speed of the upper leg type test auxiliary device 100, and perform point-to-point operation between the center of the upper leg type and the test point. Adjust the impact angle of the upper leg type test auxiliary device 100 to the impact angle calculated at one of the test points, and move the upper leg type test auxiliary device 100 along the left and right direction of the vehicle so that the center of the cross laser beam emitted by the cross laser 30 of the upper leg type test auxiliary device 100 coincides with the center of the test point.

[0046] Ensure that the impact angle of the upper leg type test auxiliary device 100 remains unchanged, adjust the relative distance between the upper leg type test auxiliary device 100 and the front of the vehicle, move the test auxiliary device so that the center of the upper leg type coincides with the test point and the upper leg type auxiliary device 100 makes the first contact with the vehicle, and cooperate with the speed measuring device to measure the impact speed of the test point when it makes the first contact. Then, perform the above operations on multiple test points.

[0047] In this process, after the impact angle and impact speed of the upper leg type test auxiliary device 100 are adjusted according to the regulations, the device coordinates of all test points can be recorded in the test equipment. When the impact test is performed on the same vehicle again, the coordinate information recorded in the test equipment can be directly used without the need to perform the marking operation again, thereby greatly improving the test efficiency.

[0048] Finally, by disassembling the fixing bracket 20 of the upper leg type test auxiliary device 100, the upper leg type foam muscle and skin are installed on the upper leg type rigid frame 11 according to the regulations, and an impact test is performed.

[0049] The upper leg type impact WAD775 test process can quickly and accurately complete the marking and marking of test points and the recording of test point coordinates by using the upper leg type test auxiliary device 100, and can conveniently and accurately perform upper leg type point alignment to ensure the accuracy and consistency of the test results. The upper leg type test auxiliary device 100 has high precision, strong repeatability and practicality, is easy to operate, can effectively improve test efficiency, and can provide strong support for the development of pedestrian protection performance.

The fixed bracket 20 is movable along the circumference of the upper leg type rigid frame 11, so that the laser 30 provided on the fixed bracket 20 is movable along the circumference of the upper leg type rigid frame 11. By adjusting the position of the fixed bracket 20 in the circumference of the upper leg type rigid frame 11, the position of the center of the cross laser beam can be adjusted, so that the center of the cross laser beam coincides with the center of the upper leg type in the moving direction of the test, so that the center of the laser beam emitted by the laser 30 can more accurately simulate the center of the upper leg type, thereby ensuring the accuracy of the test.

[0051] Reference Figure 1 Figure 3 According to some embodiments of the utility model, a ball head 12 is formed at the upper end of the upper leg type rigid frame 11, and a receiving cavity 23 for receiving the ball head 12 is formed at the upper end of the fixed bracket 20, and the opening of the receiving cavity 23 faces downward. When the fixed bracket 20 is assembled with the upper leg type rigid frame 11, the receiving cavity 23 at the upper end of the fixed bracket 20 is covered with the ball head 12 at the upper end of the upper leg type rigid frame 11, and the assembly process is relatively simple. And through the cooperation between the ball head 12 and the receiving cavity 23, the fixed bracket 20 can move along the circumference of the upper leg type rigid frame 11, thereby realizing the adjustment of the direction of the laser 30.

In addition, the clamping seat 22 is arranged on the first side 211 of the bracket plate 21 and the laser 30 is arranged on the second side 212 of the bracket plate 21, and the structure is relatively reasonable, which can ensure that the laser beam emitted by the laser 30 is not blocked by the fixed bracket 20 and the upper leg type rigid frame 11.

[0053] Optionally, the device body 10 is also provided with a connecting magnetic column 33, which is fixed on the fixed bracket 20. The connecting magnetic column 33 is magnetically adsorbed on the upper leg-type rigid frame 11 to ensure the connection strength between the fixed bracket 20 and the upper leg-type rigid frame 11. At the same time, it does not affect the movement of the fixed bracket 20 in the circumferential direction along the upper leg-type rigid frame 11.
