Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to an automobile roof blasting tool. Background Art

[0002] The front airbags at the driver's seat of the car are generally implemented in the form of dashboard airbags. At the moment of a car collision, the dashboard airbags located in the dashboard in front of the driver's seat are inflated and deployed to provide cushioning protection for the driver's seat occupants. However, with the continuous upgrading and improvement of car styling, especially with the use of various LCD screens in the dashboard area, and even lift-type large screens, the styling and deployment functions of the airbags at the dashboard position are increasingly constrained, making it difficult to meet performance and improvement requirements.

[0003] As a safety measure structure to replace the airbag in the driver's seat to complete the protection of the driver's seat, some vehicles currently use a new type of roof airbag. This roof airbag folds the airbag and installs it on the roof above the windshield. When impacted, the airbag opens downward to protect the safety of the occupants. Since this roof airbag is activated and unfolds in front of the occupants along the windshield instead of directly toward the occupants, it can provide more appropriate protection for front-seat occupants of different body shapes and weights, which has attracted the attention of relevant technicians. The design of the relevant roof airbag improves the flexibility of future car interior styles and provides excellent restraint protection performance. The safety protection level is not lower than that of the dashboard airbag of the same specification. And because this airbag is installed in the roof, it can free up the design space of the dashboard area.

[0004] After the ceiling airbag is installed inside the car roof, an airbag outlet needs to be opened so that when the car collides, the airbag can be inflated and popped out from the airbag outlet on the ceiling to protect the safety of the occupants. At present, factories usually use laser weakening systems to cut the car roof to set up the airbag outlet. However, since laser weakening equipment is usually expensive, this may lead to a higher initial investment cost, and laser weakening equipment requires professional technicians to operate with professional technical knowledge and experience, which means that additional training and the introduction of professional talents may be required, which increases the cost expenditure of the factory. Therefore, this application proposes a new solution. Summary of the invention

[0005] In order to reduce the expenditure of using laser weakening equipment as the equipment for cutting and setting the airbag outlet, the present application provides a car roof component blasting tool.
