[0002] The main driver's airbag assembly of a motor vehicle is usually arranged between the driver and the steering wheel and the dashboard, especially installed in the steering wheel. For example, the main driver's airbag assembly is first assembled with the steering wheel to form an integral part, and the integral part is then installed on the vehicle. After the steering wheel integral part is installed on the vehicle body, the cover plate of the steering column behind the steering wheel is designed to be close to the rear end of the main driver's airbag assembly, so that the rear end of the main driver's airbag assembly is shielded and cannot be seen or directly touched.

[0003] However, if the driver's airbag assembly is found to have a hardware or software fault and needs to be removed from the steering wheel, the operator will not be able to directly remove the driver's airbag assembly from the steering wheel because the operator cannot reach the rear end of the driver's airbag assembly. This generally requires the vehicle to be removed from the assembly line and moved to the repair area for special disassembly operations. For example, the steering column cover needs to be removed in the repair area before the driver's airbag assembly can be removed for repair or replacement. The entire repair process affects the production efficiency of the assembly line, requires maintenance personnel to spend a lot of time on the operation, has high repair costs, and the vehicle may be scratched during the disassembly process, resulting in additional repair hours and repair costs.

[0035] The present disclosure relates to an auxiliary disassembly tool for disassembling a driver's airbag assembly. The auxiliary disassembly tool according to the present disclosure allows an operator to quickly and conveniently disassemble the driver's airbag assembly from a steering wheel assembly that has been installed on a vehicle. The auxiliary disassembly tool according to the present disclosure is not limited by a narrow operating space, and not only allows an operator to directly complete the disassembly on a vehicle assembly line, but also does not need to disassemble other parts, greatly reducing the time cost and labor cost associated with disassembly.

[0036] Reference Figures 1 to 3 , describing various embodiments of the auxiliary removal tool disclosed in the present invention for removing a driver's airbag assembly.

[0037] The driver's airbag assembly 4 is generally suitable for being installed in the steering wheel 5 along the insertion direction toward the steering column of the steering wheel to form an integral part. The interior of the driver's airbag assembly 4 includes an elastic positioning member 43. The elastic positioning member 43 can be arranged perpendicular to the insertion direction to clamp the driver's airbag assembly 4 in the steering wheel 5. After the integral part is installed on the vehicle, the front end of the driver's airbag assembly 4 can form the central part of the steering wheel 5, and the rear end of the driver's airbag assembly 4 can be covered by the cover plate (not shown) of the steering column of the steering wheel and cannot be seen and touched from the outside.

[0038] The auxiliary disassembly tool 1 is constructed to allow the operator to quickly and conveniently disassemble the driver's airbag assembly 4 from the integral part of the steering wheel that has been installed on the vehicle without being restricted by the narrow operating space and without removing components such as the cover plate.

[0039] The auxiliary disassembly tool 1 may include a handle 3 and a disassembly head 2. The handle is for the operator to hold. The disassembly head 2 may include a connecting section 21 and a disassembly section 22. The connecting section 21 may be configured to be connected to the handle 3. The disassembly section 22 may have an inner recess 222 near its end, and the disassembly section 22 may be configured such that after the integral part is installed on the vehicle, when the steering wheel 5 rotates a certain angle around the steering column, the disassembly section 22 is suitable for extending into the rear end of the main driver's airbag assembly 4 and making the inner recess 222 cooperate with the elastic positioning member 43, so that the operator can remove the main driver's airbag assembly 4 from the steering wheel 5. In this disassembly process, it is not necessary to remove the steering wheel 5 from the vehicle, nor is it necessary to remove the cover plate of the steering column.

[0040] In some embodiments, the rear end of the driver's airbag assembly 4 may have a groove (not shown), such as an elongated groove. The disassembly section 22 is configured to extend along the groove into (e.g., inserted into) the rear end of the driver's airbag assembly 4 until the end of the disassembly section 22 exceeds the elastic positioning member 43 inside the driver's airbag assembly 4 so that the inner recess 222 of the disassembly section 22 contacts and hooks the elastic positioning member 43. This allows the elastic positioning member 43 to be deformed due to being hooked in the inner recess 222 when the inner recess 222 applies a downward force to the elastic positioning member 43, so that the driver's airbag assembly 4 can be released from the steering wheel 5 and separated from the steering wheel. In other words, this allows the operator to use the auxiliary disassembly tool 1 to contact the rear end of the driver's airbag assembly 4 through the groove without disassembling any other components, contact and hook the elastic positioning member 43 to perform the operation, and remove the driver's airbag assembly 4 from the steering wheel 5 by actuating the elastic positioning member 43. The groove 4 can have different thicknesses and lengths, and accordingly, the disassembly section can be configured to have a thickness and length matching the groove 4, so that the disassembly section can be inserted through the groove and its inner concave portion can hook the elastic positioning piece.

[0041] In other embodiments, the rear end of the driver's airbag assembly 4 may have a slit, and the disassembly section 22 is configured to extend along the slit into (for example, inserted into) the rear end of the driver's airbag assembly 4 until the end of the disassembly section 22 exceeds the elastic positioning piece 43 inside the driver's airbag assembly 4 so that the inner recess 222 of the disassembly section 22 contacts and hooks the elastic positioning piece 43.

[0042] The length of the disassembly section 22 may be between 20 mm and 45 mm, for example 37 mm long.

[0043] In one embodiment of the present disclosure, the disassembly section 22 can be formed by a cylindrical rod. In other embodiments, the disassembly section 22 can also be formed by a rod of other shapes, such as a rectangular rod, a pentagonal rod, a hexagonal rod, an octagonal rod, or a rod of other shapes. In some embodiments, the rod of the disassembly section 22 can be adapted to the shape of the groove.

[0044] In some embodiments, the steering wheel 5 can be rotated around the steering column at an angle between 45 degrees and 225 degrees, so that at least a portion of the groove at the rear end of the driver's airbag assembly 4 can be exposed between the steering wheel 5 and the cover plate of the steering column, so as to facilitate the insertion of the disassembly section 22. This allows a portion of the rear end of the driver's airbag assembly to be seen without removing the cover plate or other parts of the steering column. The angle at which the steering wheel 5 rotates around the steering column can preferably be 90 degrees or 180 degrees.

[0045] In one embodiment according to the present disclosure, the inner recess 222 of the disassembly section 22 may be in the form of an inner concave slope (eg, Figure 1 In other embodiments, the inner concave portion may also be in other forms, such as an inner concave arc surface, an inner concave square groove, etc. The shape of the inner concave portion is mainly to better match the shape of the elastic positioning member in the main driver airbag assembly.

[0046] The inner recess 222 may be arranged at a distance of no more than 3 mm from the end 221 of the disassembly section, and the maximum recess depth of the inner recess 222 may be no more than 2 mm, for example, the maximum recess depth may be 1.5 mm or 1 mm. The depth of the inner recess is mainly to better match the size of the elastic positioning member in the driver's airbag assembly. In addition, the inner recess 222 may have a length of no more than 10 mm in the extension direction of the disassembly section 22, for example, a length of 8 mm.

[0047] In some embodiments, the disassembly head 2 can be a straight rod, so that when the operator holds the handle and lifts one end of the handle toward the steering wheel, the inner recess on the other side of the disassembly head can apply a downward force to the elastic positioning member.

[0048] exist Figure 1 In the embodiment shown, the connection section 21 and the disassembly section 22 of the disassembly head 2 may be configured to have an angle with each other, that is, the disassembly head may be hook-shaped. In this embodiment, the connection section 21 of the disassembly head 2 may include a straight section and a curved transition section between the connection section 21 and the disassembly section 22. The straight section may have a length of, for example, 30 mm, and the curved transition section may have a radius of, for example, between 10 mm and 20 mm.

[0049] exist Figure 1In the illustrated embodiment, the angle between the connecting section and the disassembling section may be, for example, between 30 and 70 degrees. This allows the inner recess 222 to more conveniently apply a pressing force to the elastic positioning member 43 when the operator holds the handle 3 and applies force toward the steering wheel 5 .

[0050] In some embodiments, the connection section 21 and the disassembly section 22 of the disassembly head can be assembled together in a detachable manner or a non-detachable manner, for example, by threaded connection, latch connection, welding, etc. In other embodiments, the connection section 21 and the disassembly section 22 of the disassembly head can also be made in the form of a single part.

[0051] In some implementations, the handle 3 and the disassembly head 2 may also be assembled together in a detachable manner or a non-detachable manner, such as by threaded connection, latch connection, welding, etc., or made into a single part.

[0052] exist Figure 1 In the illustrated embodiment, the handle 3 is substantially cylindrical. In other embodiments, the handle may be selected from a linear handle, a T-shaped handle, and an L-shaped handle. The handle 3 may have a length, for example, between 30 mm and 40 mm (e.g., a length of about 35 mm) to facilitate the operator to grasp and operate. The shape and length of the handle are mainly considered to be the size of the operating space. For example, the handle is detachable and can be selected and replaced in the above shapes.

[0053] The surface of the handle and / or the disassembly head may be provided with, for example, a protective cover to prevent the vehicle from being scratched during the disassembly operation.

[0054] Reference Figure 2 and Figure 3 In some embodiments of the present disclosure, the elastic positioning member 43 may be, for example, a U-shaped spring. The U-shaped spring may be arranged in the steering wheel with its opening facing upward, and the two ends of the U-shaped spring are used to cooperate with the positioning member 51 in the steering wheel to fix the driver's airbag assembly 4 in the steering wheel 5.

[0055] exist Figure 2 , Figure 3 In the illustrated embodiment, when the steering wheel is rotated, for example, 180 degrees to expose the groove at the rear end of the driver's airbag assembly 4, the disassembly section 22 of the disassembly head 2 is inserted into the rear end of the driver's airbag assembly 4 along the groove until the inner concave portion 222 of the disassembly section 22 of the disassembly head 2 hooks the U-shaped bottom of the U-shaped spring. At this time, the operator applies a force to the U-shaped bottom by operating the auxiliary disassembly tool 1, so that the U-shaped spring is deformed, and the two ends no longer cooperate with the positioning member 51 in the steering wheel, so that the U-shaped spring no longer clamps the driver's airbag assembly 4 in the steering wheel 5, thereby achieving separation from the steering wheel.

[0056] In other embodiments, the elastic positioning piece may also be in other shapes. In any shape, as long as the inner concave portion 222 of the disassembly section of the auxiliary disassembly tool 1 of the present disclosure can hook the elastic positioning piece, it can be used to disassemble the main driver's airbag assembly 4.

[0057] Although the present disclosure has been disclosed as above in the form of a preferred embodiment, it is not intended to limit the present disclosure. Any technical personnel in this field can make possible changes and modifications to the technical solution of the present disclosure by using the methods and technical contents disclosed above without departing from the spirit and scope of the present disclosure. Therefore, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present disclosure without departing from the content of the technical solution of the present disclosure shall fall within the protection scope of the technical solution of the present disclosure.
