Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of blasting impact force tool fixture, especially to a tool fixture for measuring PAB blasting impact force. BACKGROUND

[0002] The arrangement position of the co-driver PAB airbag in the whole vehicle and the design of the peripheral related parts (front windshield, instrument panel, air outlet, front liquid crystal large screen, etc.) all play a crucial role in the explosion process of the co-driver PAB airbag. For example, the distance and angle setting value of the upper surface of the instrument panel from the front windshield will greatly affect the impact force of the windshield glass when the co-driver PAB airbag explodes. In order to clearly determine the key parameter design and propose the requirements for the co-driver airbag part, it is necessary to know the impact force value of the front windshield glass after the co-driver airbag explodes in this environmental part design, so as to determine whether the front windshield glass can withstand the airbag impact.

[0003] At present, the Chinese patent application with the publication number CN 114459717 A discloses a safety airbag point explosion impact force testing device, which comprises a base frame having a first mounting table and a second mounting table; the first mounting table and the second mounting table are parallel to the horizontal plane; an airbag fixing assembly is fixed on the first mounting table; a windshield simulation board is installed on the second mounting table through a support assembly; the lower end of the windshield simulation board is hingedly connected with the support assembly; the upper end of the windshield simulation board is installed on the support assembly through a pulley set, and the included angle between the windshield simulation board and the first mounting table can be adjusted by adjusting the pulley set; a dynamometer; the force value sensor of the dynamometer is pasted on the windshield simulation board.

[0004] The existing patent application adjusts the Z-direction distance from the intersection of the co-driver airbag center axis and the instrument panel to the windshield glass (windshield simulation board) and the angle between the co-driver airbag center axis and the windshield glass (windshield simulation board) to test the impact force of the co-driver airbag subsystem. However, the patent adjusts the angle of the windshield simulation board through the pulley set and measures the impact force value by pasting the force value sensor on the windshield simulation board. When the airbag explodes and impacts, the windshield simulation board moves upward, thereby weakening the impact force. However, the windshield on the car is fixed, which causes a certain deviation between the measured impact force value and the actual value, and improvement is necessary. UTILITY MODEL CONTENTS
