Detailed Description

The invention will now be further described with reference to the accompanying drawings.

The utility model relates to a side gas curtain fixed knot constructs, including preventing the rotor, the side or the top of preventing rotor 1 are equipped with and install couple 2 in advance, and the tip of installing couple 2 in advance extends along preventing 1 plane normal direction of rotor, and the tip of installing couple 2 in advance is equipped with hook-like structure, and install couple 2 in advance and pass the trompil of auricle 3, panel beating 4 to adopt hook-like structure to block the trompil.

In the case of the example 1, the following examples are given,

referring to fig. 1, in this example, the pre-installed hooks 2 are disposed on both sides of the rotation preventing piece 1, the end portions of the pre-installed hooks 2 extend along the normal direction of the plane of the rotation preventing piece 1, and the end portions of the pre-installed hooks 2 are provided with V-shaped hook structures. The opening size of the hook-shaped structures is larger than the opening sizes of the lug pieces 3 and the sheet metal 4, and the two hook-shaped structures are in the same direction.

In this example, there are two assembly scenarios, one is to assemble on the side curtain ear piece, and the other is to assemble on the vehicle body sheet metal. The assembly process and principle are the same for both scenarios.

Referring to fig. 2 and 3, during assembly, the hook 2 to be pre-installed needs to pass through the hole along the normal direction of the hole plane of the lug plate 3 and the metal plate 4 under the action of external force, and under the condition of extrusion of the edge of the hole, the V-shaped hook-shaped structure is elastically deformed, so that the size of the hole is reduced to ensure that the hole is passed through. After the hole is opened, the periphery is extruded and disappears, and the V-shaped hook-shaped structure rebounds to the original state. Under the condition of no destructive external force, the pre-installed hook 2 cannot be automatically separated, so that a stable anti-falling structure is formed, and the pre-installed function is realized.

In the case of the example 2, the following examples are given,

referring to fig. 4, the pre-installed hook 2 is arranged at the top of the rotation preventing piece 1, the end of the pre-installed hook 2 extends along the normal direction of the plane of the rotation preventing piece 1, and the end of the pre-installed hook 2 is provided with a T-shaped hook structure. The width of the end of the hook-shaped structure is larger than the width of the part connected with the anti-rotation piece 1. The two sides below the anti-rotation piece 1 are provided with positioning hooks 5, and the end parts of the positioning hooks 5 extend along the direction parallel to the plane of the anti-rotation piece 1. Referring to fig. 5, the aperture width of the ear panel 3 matches the width of the hook-like structure. Referring to fig. 6, the width of one end of the opening of the metal plate 4 is matched with the width of the hook-shaped structure, and the width of the other end of the opening of the metal plate 4 is smaller than the width of the hook-shaped structure.

In this example, there are two assembly scenarios, one is to assemble on the side curtain ear piece, and the other is to assemble on the vehicle body sheet metal.

Referring to fig. 7, in the assembly process on the side curtain ear, the positioning hooks 5 are assembled into the positioning holes 6 on the surface of the ear 3 in a direction parallel to the plane of the opening. Thereafter, the pre-mount hook 2 is fitted into the opening of the tab 3 in the normal direction of the opening plane by an external force. At this moment, the connection of the anti-rotation piece 1 and the lug piece 3 forms a stable triangular structure, and the anti-falling function is realized.

During the assembly process on the automobile body panel beating, install couple 2 in advance and go deep into the trompil one end of panel beating 4 along trompil plane normal direction, afterwards, under the effect of external force, install couple 2 in advance and remove to the trompil other end of panel beating 4 along the direction that is on a parallel with the trompil plane. At the moment, the width of the hook-shaped structure of the pre-installation hook 2 is larger than that of the other end of the opening of the metal plate 4, so that the anti-rotation piece 1 cannot automatically fall off, and the pre-installation function is realized.
