Description

Technical Field

[0001] This utility model relates to the field of airbag technology, and in particular to a special detonation tool for pedestrian protection airbags. Background Technology

[0002] With the development of automotive safety technology, pedestrian protection airbags have become an important piece of equipment for improving the pedestrian protection performance of vehicles. During the research, development, verification, and production of pedestrian protection airbags, frequent detonation tests are required to verify key performance indicators such as deployment pattern, detonation timing, and explosion volume. Currently, the common testing method is to simply fix the airbag module in a general fixture or test chamber and detonate it. This method has several drawbacks: 1. Space Occupancy and Cost: Individual test chambers are typically bulky. If airbag deployment tests and pedestrian protection tests use different chambers, it will occupy a large amount of laboratory space, and the equipment purchase cost will also be higher.

[0003] 2. Low testing efficiency: The process of installing, adjusting, and replacing the test component is cumbersome and cannot meet the needs of efficient R&D.

[0004] 3. Inconvenient installation and fixing: Without dedicated tooling, fixing and installing the airbag module during the test may be difficult, resulting in problems such as inaccurate positioning and poor repeatability, which affects the accuracy and reliability of the test data.

[0005] 4. Folding and Shape Control: The folding method of an airbag is crucial to its deployment shape. Some innovative folding methods require specialized folding fixtures, while ordinary fixing devices may not be able to meet these special folding and deployment shape control requirements. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose a special ignition tool for pedestrian protection airbags, which solves the problems in the background art.

[0007] To achieve the above objectives, this utility model provides a dedicated detonation fixture for pedestrian protection airbags, comprising a base frame, an inclined windshield profile plate detachably mounted on one end of the top of the base frame via a bolt assembly, a box mounting platform mounted on the side of the inclined bottom end of the windshield profile plate on the top of the base frame, and a capping mechanism movably mounted on the side of the box mounting platform on the top of the base frame; a triangular frame is mounted on the side of the base frame near the capping mechanism, one end of the capping mechanism is rotatably connected to the top of the triangular frame away from the base frame, and the other end of the capping mechanism is connected to the top of the base frame via two hinge mechanisms.

[0008] Preferably, the box mounting platform includes two L-shaped brackets that are detachably fixed to the top of the base frame by bolt assembly. The two L-shaped brackets are spaced apart, and a middle support frame is provided on the top of the base frame between the two L-shaped brackets. Both the L-shaped brackets and the middle support frame are provided with screw holes adapted to the pedestrian protection airbag box.

[0009] Preferably, the windshield profile plate is inclined downwards towards the box mounting platform, and a baffle is provided on the side of the windshield profile plate closest to the box mounting platform.

[0010] Preferably, the hinge mechanism includes a vertical plate that is detachably fixed to the top of the base frame by a bolt assembly. Two connecting arms are rotatably connected to the top of the vertical plate. The top of the two connecting arms is rotatably connected to a mounting plate. The top of the mounting plates of the two hinge mechanisms are detachably fixed to the cover mechanism by a bolt assembly.

[0011] Preferably, the distance between the two connecting arms and the vertical plate is greater than the distance between the two connecting arms and the mounting plate.

[0012] Preferably, the end of the cap mechanism connected to the triangular frame is a connecting rod, and a connector is provided at the end of the connecting rod near the triangular frame. A connecting block is provided at the top of the triangular frame, and the connecting block has a connecting groove for matching the connector. The connector is inserted into the connecting groove and the connector is rotatably connected to the connecting block through a shaft. The shaft is fixed on the connecting block, and a locking pin is threaded into the connector. The locking pin contacts the shaft to limit the movement of the shaft.

[0013] Preferably, both the base frame and the triangular frame are equipped with transport wheels at their bottoms.

[0014] The beneficial effects of this utility model are as follows: This utility model assembles the pedestrian protection airbag housing onto the housing mounting platform using bolt assemblies, which facilitates assembly and disassembly. An inclined windshield profile plate is provided on the side of the housing mounting platform to simulate a car's windshield. This windshield profile plate is detachable, allowing for windshield replacement as needed. On the other side of the housing mounting platform, a movable opening mechanism is provided via a hinge mechanism to simulate a car's engine hood. The opening mechanism can be adjusted to simulate different opening angles of the engine hood. Transport wheels allow the entire fixture to be moved freely. The entire fixture can quickly adapt to pedestrian protection airbags of different shapes, sizes, and installation points.

[0015] The box-mounting platform uses two L-shaped brackets and a central support frame to install the pedestrian protection airbag box. It is installed with bolt assemblies, allowing for detachable assembly and good adaptability. The windshield contour plate is equipped with baffles to prevent the airbag from bursting inward, ensuring that the airbag can deploy along the windshield.

[0016] The hinge mechanism connects the mounting plate to the two connecting arms via the rotation of the upright plate, allowing the cap mechanism to be installed on the mounting plate. This enables the angle adjustment of the cap mechanism. The other end of the cap mechanism is connected to the connecting slot of the connecting block of the triangular frame via the connecting rod's connecting head and the shaft rod through the connecting rod's connecting slot. The connecting head is inserted into the locking pin and contacts the shaft rod to limit the shaft rod's position, thereby limiting the position of the connecting head and fixing the angle of the cap mechanism.
