Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology, specifically relating to a tool for removing and protecting steering wheel airbags, and a method for using the tool. Background Technology

[0002] Currently, some car steering wheel airbags are clipped onto the steering wheel. When it is necessary to remove the steering wheel airbag for testing and repair, using ordinary screwdrivers or unprofessional tools is not only difficult to remove, but can also easily damage the airbag and surrounding parts and plastic components that do not need to be replaced, thus affecting the appearance and lifespan of the steering wheel.

[0003] With the increase in car ownership in the 21st century, the frequency of vehicle maintenance and modification has increased, and the frequency of airbag removal has also continued to rise.

[0004] Current technology for removing steering wheel airbags often requires two people. When removing an airbag, one operator needs to use both hands to push the airbag fixing clips with the special removal tool, while the other operator uses a pry bar or other tools to remove the airbag. The entire removal process is complicated, requires two operators, and is inefficient.

[0005] Furthermore, currently, automotive steering wheel airbags include two-point snap-fit ​​airbags and three-point fixed airbags. Separating these two types of airbags from the steering wheel relies entirely on existing tools, such as screwdrivers and hex wrenches; no specialized tools are available. Using these existing tools to remove two-point snap-fit ​​or three-point fixed airbags requires working directly in front of the steering wheel in a confined space, making airbag removal difficult. The success of the task depends heavily on the operator's skill. If the operator is inexperienced, it can easily result in damage to the airbag, scratches on the steering wheel and surrounding parts, or even prevent the airbag from being removed from the steering wheel altogether.

[0006] Existing airbag removal tools only have removal functions and no protection functions. After the removal tool opens the locking mechanism, the airbag still needs to be pulled out manually. This process has a large inertia and cannot accurately control the pulling force, which can easily cause accidents such as damage to the locking mechanism and breakage of the airbag wiring harness. It is impossible to complete the removal work with high quality, high efficiency and high precision. Summary of the Invention

[0007] To address the problems of low disassembly efficiency, poor precision, waste of parts, and repetitive manual work caused by easy damage to locking mechanisms and airbag wiring harnesses during airbag removal, this invention provides a steering wheel airbag removal and protection tool. It can achieve precise control disassembly, non-destructive disassembly, disassembly protection, and flexible assembly of airbags, reducing the damage rate to 0%.

[0008] The objective of this invention is achieved through the following technical solution, as shown in the accompanying drawings:

[0020] Functional and Principle Description of the Invention:

[0021] Steering wheel adaptation: First, fix the fixing claw to the steering wheel by adjusting the lateral distance of the fixing mechanism; then, adjust the vertical distance of the fixing claw by adjusting the connecting bolts between the fixing claw and the fixing rod to achieve the adaptation and installation of steering wheels of different sizes.

[0022] Airbag adaptation: By adjusting the installation position of the airbag removal rod along the long groove of the base, the pry bar at the end of the single-point adjusting screw can move laterally, thus enabling the adaptation and installation of airbags of different sizes.

[0023] Single-point pre-extraction of the airbag: Rotate the nut between the single-point adjusting screw and the base. The rotational motion of the nut is converted into the linear motion of the screw. The single-point adjusting screw moves vertically and drives the pry bar at the end of the screw to move vertically, thereby realizing the single-point pre-extraction of the airbag.

[0024] Single-sided airbag removal: In this embodiment, the disassembly rod adjustment mechanism is designed with 3 linkage platforms. After the airbag is pre-removed at one point, the single-sided adjustment nut is rotated. Through the screw transmission mechanism, the single-sided adjustment nut will drive the linkage platform and the two single-point control screws to move in the Z direction, thereby realizing the single-sided removal of the airbag.

[0025] Complete airbag removal: If the airbag has been removed from both sides but is still not completely removed, turn the connecting nut between the main linkage and the main adjusting screw. Through the transmission of the main adjusting screw, the main linkage, the two single-sided linkages, and the four single-point adjusting screws will move vertically together, thereby achieving complete airbag removal.

[0026] The present invention has the following beneficial effects:

[0027] 1. Precise control of disassembly: The disassembly force is precisely controlled by the small pitch of the screw drive mechanism.

[0028] 2. Non-destructive disassembly: Through precise disassembly, the damage rate of locking mechanisms, airbag wiring harnesses, etc. is 0%.

[0029] 3. Disassembly protection: If the airbag pops out accidentally during the disassembly process, the base will block it, preventing injury to the operator.

[0030] 4. Flexible assembly: Through on-site testing, this invention can be used on all models of a certain vehicle type, demonstrating strong versatility. Attached Figure Description
