The airbag clamping member 12 defines a through hole 121 extending through the top surface 122 of the clamping member and the bottom surface 123 of the clamping member. The through hole 121 It is a receiving space 121. The air bag clamping member 12 is provided with a first positioning member 128 on the top surface 122 of the clamping member. The first positioning member 128 can be a positioning protrusion or a positioning groove. The airbag holder 12 may have a columnar structure in which the end faces are "back" shaped. In other embodiments, the first positioning member 128 may also be disposed on the side surface 129 connecting the clamping member top surface 122 and the clamping member bottom surface 123.

The airbag 11 includes a first wall 111, a second wall 112 opposite the first wall 111, and a side wall 115 connecting the first wall 111 and the second wall 112. The airbag 11 is divided into a carrying area 113 and a bonding area 114 surrounding the carrying area 113. The first wall 111, the second wall 112, and the side walls 115 collectively enclose the balloon chamber 116. The bearing zone 113 is located at a central position of the airbag 11, and the bonding zone 114 is an edge region of the periphery of the airbag 11, and the projection of the bonding zone 114 along the bottom surface 123 of the clamping member is annular. The first wall 111 and the second wall 112 are connected to the bearing area 113 and the bonding area 114. The bonding portion 114 may be bonded to the bottom surface 123 of the holder by bonding and close one end of the bottom surface 123 of the holder of the airbag holding member 12. When the joint region 114 is combined with the bottom surface 123 of the clamp member, the second wall 112 is in contact with the bottom surface 123 of the clamp member, the airbag 11 can protrude into the through hole 121, and the second wall 112 can pass through the through hole 121 and pass through The hole 121 is convex. The first wall 111 can extend into the through hole 121 and be recessed toward the panel carrier 10 to form a receiving cavity 101. The first wall 111 is an inner wall of the receiving cavity 101. The flexible panel 201 is carried on the load bearing area 113 and on the second wall 112. In the airbag 11 of the present embodiment, the thickness of the airbag chamber 116 gradually increases in the direction along the center of the load-bearing area 113 to the joint region 114, wherein the thickness of the airbag chamber 116 refers to the thickness of the airbag chamber 116 after inflation. The airbag 11 can be elastically deformed when subjected to a force, and the airbag 11 can be made of a soft elastic material such as rubber, silica gel or raw rubber. In other embodiments, the bond zone 114 can be secured to the bottom surface 123 of the clamp by fasteners 105, which include bolts, pressure plates.

For example, when the first positioning member 128 is a positioning protrusion, the second positioning member 25 is a positioning groove; When the first positioning member 128 is a positioning groove, the second positioning member 25 is a positioning protrusion. The upper cover 24 of the present embodiment has an integral structure. In other embodiments, the upper cover 24 can be a split structure.

The cover clamp 23 includes opposite clamp bottom surfaces 232. The clamp bottom surface 232 is formed with a mounting portion 21, and the mounting portion 21 can be a positioning groove matching the cover plate 202. At this time, the mounting portion 21 preferably mounts a curved shape cover plate. 202. The cover clamp 23 is housed in the upper cover cavity 242. The cover plate 202 can be mounted to the mounting portion 21. In other embodiments, the mounting portion 21 can also be part of the bottom surface 232 of the clamp. In this case, the mounting portion 21 is preferably mounted with a planar shaped cover plate 202.

When the upper cover 24 containing the cover clamp 23 is mounted on the airbag clamping member 12, the upper cover bottom surface 241 is engaged with the clamping member top surface 122, and the second positioning member 25 is engaged with the first positioning member 128, and the upper cover cavity The body 242 is in communication with the accommodating space 121, and the cover plate 202 corresponds to the flexible panel 201 provided on the airbag 11, and the upper cover 24, the cover clamp 23, the airbag 11, and the airbag holder 12 together form the air suction chamber 102.

The suction chamber 102 may be a closed cavity, and the upper cover 24 is also formed with a suction port 103 communicating with the suction chamber 102. The air pipe of the air suction device is connected to the air suction port 103 and can extract the air in the air suction chamber 102 such that the first air pressure in the receiving cavity 101 is greater than the second air pressure in the air suction chamber 102, so that the air bag 11 is carried toward the cover plate. The belt 20 moves to bring the flexible panel 201 into contact with the cover plate 202. In other embodiments, the air suction port 103 can also be opened on the airbag holder 12.

The air tube of the inflator can be sleeved on the side surface 129 to enable the air tube of the inflator to form a closed cavity with the receiving cavity 101. The first air pressure that can be inflated into the receiving cavity 101 into the receiving cavity 101 is greater than the second air pressure in the airing cavity 102, so that the airbag 11 moves toward the cover carrier 20 to drive the flexible panel 201 and the cover plate 202 to be attached. Hehe.

When the first air pressure in the receiving cavity 101 is greater than the second air pressure in the air suction chamber 102, the airbag 11 is subjected to a resultant force toward the side of the air suction chamber 102 under the action of the first air pressure and the second air pressure, and the airbag 11 is in the airbag 11 Under the combined force, the side of the pumping chamber 102 is deformed and the bearing area 113 is moved toward the side of the pumping chamber 102, so that the carrying area 113 drives the flexible panel 201 disposed on the carrying area 113 to move toward the cover plate 202 and is flexible. The panel 201 is attached to the cover plate 202. Since the joint region 114 is combined with the bottom surface 123 of the clamp member and fixed to the bottom surface 123 of the clamp member, the displacement of the airbag 11 from the load-bearing region 113 of the joint region 114 is greater under the action of the first air pressure and the second air pressure. Generally, the displacement of the center position of the load-bearing area 113 is the largest, and when the flexible panel 201 is disposed at the center position of the load-bearing area 113 (when the center position of the flexible panel 201 corresponds to the center position of the load-bearing area 113), the flexible panel 201 The center first contacts the cover plate 202 and is attached to the cover plate 202. Then, the flexible panel 201 gradually fits on the cover plate 202 from the center toward the edge, and the flexible panel 201 gradually fits on the cover plate 202 to avoid the flexible panel 201. Air bubbles are generated between the cover plate 202. In other embodiments, when the end of the flexible panel 201 is disposed at a central position of the load bearing area 113, the end of the flexible panel 201 corresponding to the central position of the load bearing area 113 first contacts the cover plate 202 and with the cover plate 202. When fitted together, the flexible panel 201 is gradually attached to the cover plate 202 in the direction toward the other end.

The bonding apparatus 100 of the embodiment of the present invention controls the first air pressure in the receiving cavity 101 to be larger than the second air pressure in the air suction chamber 102, and the airbag 11 is deformed and moved toward the side of the cover 20 to be disposed on the airbag 11. The flexible panel 201 moves toward the cover plate 202, so that the flexible panel 201 fits on the cover plate 202, so that there is no need to additionally provide a device for supporting the flexible panel 201 and driving the flexible panel 201 to move, thereby implementing the embodiment of the present invention. The structure of the bonding apparatus 100 is simpler.

The bonding apparatus 100 of the embodiment of the present invention also has the following beneficial effects: the thickness of the airbag cavity 116 gradually increases in the direction from the center of the load-bearing zone 113 to the bonding zone 114, so that the center of the load-bearing zone 113 is generated under the same air pressure. The shape change is big.
