[0047] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0048] The following describes the implementation methods of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that, in the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0049] It should be noted that various aspects of the embodiments within the scope of the appended claims are described below. It should be apparent that the aspects described herein can be embodied in a wide variety of forms, and any specific structure and / or function described herein is merely illustrative. Based on the present application, it should be understood by those skilled in the art that an aspect described herein can be implemented independently of any other aspect, and two or more of these aspects can be combined in various ways. For example, any number and aspect described herein can be used to implement the device and / or practice the method. In addition, other structures and / or functionalities other than one or more of the aspects described herein can be used to implement this device and / or practice this method.

[0050] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0051] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the examples can be practiced without these specific details.

[0052] The ear 20 is usually a strip-shaped structure, and the ear hole is also usually a round hole structure. After the ear 20 is inserted into the buckle 10 and installed on the air curtain, the relative position of the ear 20 and the buckle 10 will change during the air curtain process, causing the employees of the vehicle manufacturer to adjust the ear 20 and the buckle 10 when loading the vehicle, which increases the workload of the employees of the vehicle manufacturer and reduces their work efficiency.

[0053] In addition, since the ear hole does not avoid the push switch on the buckle 10, the push switch is easily squeezed by the side wall of the ear hole during transportation, causing the buckle 10 to be stuck and unable to be installed, which further prevents the air curtain from being successfully installed.

[0054] Therefore, in order to facilitate the OEM's loading personnel to safely, accurately and quickly install the air curtain on the vehicle body, the vehicle manufacturer not only puts forward new requirements for the air curtain to prevent the metal sharp corners from being exposed, but also requires the air curtain supplier to design the installation buckle 10 to limit the position (to prevent the buckle 10 from rotating or shifting in the through hole) and prevent the plastic part from being pressed in (to prevent the push switch from being pressed in). When using the conventional circular mounting hole of the hanging ear 20, in order to limit the installation buckle 10 and prevent the plastic part from being pressed in, it is generally chosen to add a plastic anti-rotation clip, which has a hard rectangular mounting hole, which can effectively prevent the buckle 10 from rotating and the two ends of the plastic part from being pressed in, but it will increase the material cost and the man-hour cost of installing the plastic part. Although it is effective, it is not economical.

[0055] Based on this, this specification embodiment proposes a processing solution: Figures 1 to 3 As shown, an air curtain connection structure of the present invention provides a plurality of special-shaped through holes on the hook body 21, and uses the special-shaped through holes to fit the structure of the buckle 10 while avoiding compression of the press switch on the press member 12, and can also form multiple rotation constraints on the buckle 11, thereby achieving the function of limiting the buckle 10 and preventing the press switch from being pressed in.

[0056] Furthermore, by providing a plurality of openings 215 on the hook body 21, the openings 215 can accommodate metal corners on the bottom panel 111 of the buckle 11 to prevent the metal corners from being exposed, thereby protecting the vehicle occupants and the airbag.

[0057] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0058] Example 1

[0059] like Figures 1 to 4 As shown, an air curtain connection structure of an embodiment of the present invention includes a buckle 10 and a hook 20, the buckle 10 includes a buckle member 11, the buckle member 11 includes a bottom panel 111 and two buckle side walls 112 extending from the bottom panel 111, and the first part between the two buckle side walls 112 forms a first hollow portion 113.

[0060] The buckle 11 is used to cooperate with the mounting part on the vehicle body to install the hanging ear 20 on the vehicle body.

[0061] Specifically, two ends of the bottom panel 111 of the buckle 11 are bent to one side to form two buckle side walls 112 of the buckle 11, and the parts of the two buckle side walls 112 close to the bottom panel 111 are the first parts, and the two first parts are spaced apart and located on both sides of the opening set on the bottom panel 111 to form a first hollow part 113.

[0062] Furthermore, the hanging ear 20 includes a hanging ear body 21 , which is a bar-shaped structure and has a plurality of through holes arranged at intervals.

[0063] When installing the hanging ear 20, the hanging ear body 21 needs to be folded, and the multiple through holes are connected to each other, so that the buckle 11 can pass through the multiple through holes and be installed inside the multiple through holes.

[0064] For example, when the ear hook body 21 is folded so that the centers of the multiple through holes are on the same axis, the buckle 11 is passed through the multiple through holes in sequence. At this time, under the restriction of the multiple through holes, the buckle 11 is initially limited to the multiple through holes.

[0065] The plurality of through holes may include a plurality of irregular-shaped through holes or a combination of irregular-shaped through holes and round holes.

[0066] Furthermore, the multiple through holes include a first through hole 211, the inner wall of the first through hole 211 is provided with a first protrusion 2111 extending into the interior of the first through hole 211, and the width of the first protrusion 2111 matches the width of the first hollow portion 113; wherein, after the folding ear body 21 is folded so that the multiple through holes are axially correspondingly arranged, the fastener 11 passes through the multiple through holes in sequence, and the first protrusion 2111 is clamped in the interior of the first hollow portion 113, so that the two fastener side walls 112 limit the rotation of the fastener 11 in the multiple through holes through the first protrusion 2111.

[0067] The basic hole of the first through hole 211 may be a circular hole or a rectangular hole to match the shape of the two buckle side walls 112 of the buckle 10 .

[0068] The first protrusion 2111 extends toward the middle of the first through hole 211 and has a certain width, so that the first protrusion 2111 can be inserted into the first hollow portion 113 and connected with the first hollow portion 113 .

[0069] Among them, the width of the first protrusion 2111 can be slightly smaller than the width of the first hollow portion 113, so that the first protrusion 2111 can be inserted into the first hollow portion 113; the width of the first protrusion 2111 can be equal to the width of the first hollow portion 113, so that the first protrusion 2111 is just stuck in the first hollow portion 113.

[0070] The first protrusion 2111 may be a rectangular structure or an inverted trapezoidal structure, so that two edges of the first protrusion 2111 can cooperate with the buckle side wall 112 to limit the buckle 11 .

[0071] Furthermore, there are two first protrusions 2111 that are oppositely disposed and both extend toward the middle portion of the first through hole 211 to be clamped on both sides of the first hollow portion 113 to increase the limiting ability of the first protrusions 2111 on the buckle 10 .

[0072] There may be one or more first through holes 211 to increase the limiting strength of the buckle 11 .

[0073] For example, when there are two first through holes 211, after the ear hook body 21 is folded, the two first through holes 211 are overlapped so that the two first protrusions 2111 in the two first through holes 211 are both stuck in the first hollow portion 113 to increase the limiting ability of the buckle 11.

[0074] In this embodiment, the shape of the first through hole 211 is changed so that the first protrusion 2111 cooperates with the buckle side wall 112 of the first hollow portion 113 to limit the buckle 11, thereby preventing relative rotation between the buckle 11 and the ear hook body 21.

[0075] Furthermore, a clamping groove 2112 is formed between the side wall of the first protrusion 2111 and the side wall of the first through hole 211 , and the clamping groove 2112 is used to clamp the buckle side wall 112 .

[0076] Among them, the width of the buckle 10 matches the width of the buckle side wall 112. After the buckle 11 enters the first through hole 211, the buckle side wall 112 is clamped in the slot 2112 to limit the buckle side wall 112 through the slot 2112 to prevent the buckle 11 from rotating in the first through hole 211.

[0077] Furthermore, a second hollow portion 114 is formed in the second portion between the two snap side walls 112 , and a fitting portion 115 is respectively provided in the middle portion of the two snap side walls 112 , and the two snap side walls 112 are fitted together through the fitting portion 115 , wherein one fitting portion 115 extends toward the second hollow portion 114 to form an extended protrusion 116 .

[0078] Specifically, the portion between the two snap-on side walls 112 away from the bottom panel 111 is the second hollow portion 114, and the portions of the two snap-on side walls 112 away from the bottom panel 111 are also spaced apart to form the second hollow portion 114; between the first portion and the second portion of the snap-on side wall 112 is the middle portion of the snap-on side wall 112, and the middle portion of the snap-on side wall 112 is engaged through the engaging portion 115 so that the two snap-on side walls 112 are connected to each other.

[0079] The extending protrusion 116 may be a triangular structure.

[0080] Furthermore, the end of the buckle side wall 112 is folded toward the direction of the bottom panel 111 to the second hollow portion 114 and then flanged to form a buckle convex corner 13. The buckle convex corner 13 can be used to connect to the vehicle body and, when the hook body 21 is folded and put on the buckle 11, it can block the folded hook body 21 to prevent the hook body 21 from detaching from the buckle 11 during transportation.

[0081] Preferably, the folded ear hook body 21 is sleeved between the buckle convex corner 13 and the bottom panel 11 .

[0082] Furthermore, if Figure 5 As shown, the multiple through holes include a second through hole 212, a first avoidance groove 2121 is formed on the inner wall of the second through hole 212, two inner convex portions 2122 are respectively formed on both sides of the first avoidance groove 2121, and the two inner convex portions 2122 respectively extend to the middle part of the second through hole 212; wherein, the second through hole 212 is arranged corresponding to the second hollow portion 114, the first avoidance groove 2121 avoids the extension convex portion 116, and the two inner convex portions 2122 are inserted between the extension convex portion 116 and the two buckle side walls 112 to limit the rotation of the buckle 11 in the multiple through holes.

[0083] The second through hole 212 may be a circular hole or a rectangular hole.

[0084] The width of the first avoiding groove 2121 is equal to the maximum width of the extending protrusion 116 , so that the first avoiding groove 2121 can completely avoid the extending protrusion 116 .

[0085] The inner protrusions 2122 are located on both sides of the first avoidance groove 2121 , and can extend into the second hollow portion 114 after the first avoidance groove 2121 avoids the extended protrusions 116 , so as to cooperate with the buckle side walls 112 forming the second hollow portion 114 to limit the buckle 11 .

[0086] The inner protrusion 2122 may be in a triangular shape or the like, so as to be easily inserted between the extending protrusion 116 and the buckle side wall 112 .

[0087] Among them, the number of first avoidance grooves 2121 is the same as the number of extension protrusions 116. For example, when there are two extension protrusions 116 and they are arranged opposite to each other, there are also two first avoidance grooves 2121 and they are arranged on two opposite sides of the first through hole 211. At this time, there are four inner protrusions 2122.

[0088] When the first avoidance groove 2121 avoids the extension protrusion 116, the extension protrusion 116 cooperates with the first avoidance groove 2121 to limit the buckle 11. Specifically, when the buckle 11 rotates, the two side walls of the first avoidance groove 2121 can prevent the extension protrusion 116 from rotating with the buckle 11.

[0089] Furthermore, an avoidance angle 2123 is provided on one side of the inner protrusion 2122 close to the edge of the buckle side wall 112 for avoiding the edge of the buckle side wall 112 to prevent the inner protrusion 2122 from turning outward or being unable to cooperate, connect or contact with the edge of the buckle side wall 112.

[0090] Furthermore, the bottom panel 111 also includes an opening located between the two buckle side walls 112 .

[0091] The buckle 10 also includes a pressing piece 12, which includes two oppositely arranged extension parts 121 and a switch part 122 located at the end of the extension part 121. The two extension parts 121 pass through the opening and enter between the two buckle side walls 112, so that the two switch parts 122 extend from the hole grooves opened on the buckle side walls 112 respectively, and the switch part 122 and at least part of the second hollow part 114 are located on the same plane.

[0092] The hole groove is opened along the length direction of the buckle side wall 112 .

[0093] The pressing member 12 includes a pressing portion 123 and two extending portions 121 disposed on the pressing portion 123 . A switch portion 122 is disposed on one side of the two extending portions 121 away from the pressing portion 123 .

[0094] One end of the extension portion 121 is fixedly disposed on the pressing portion 123, and the other ends of the two extension portions 121 can be moved closer to each other when pressed. The switch portion 122 is a plate-like structure and is disposed along the length direction of the extension portion 121, and at least partially extends out of the hole slot opened on the buckle side wall 112 to be located outside the two buckle side walls 112.

[0095] Furthermore, the second through hole 212 further includes two second avoiding grooves 2124 , which are respectively formed on two inner walls of the second through hole 212 and are used to avoid the parts of the two switch parts 122 extending from the holes of the buckle side wall 112 .

[0096] The size of the second avoiding groove 2124 is related to the size of the protruding portion of the switch portion 122 .

[0097] Among them, the present application sets a second avoidance groove 2124 on the second through hole 212, so that the first avoidance groove 2121 is used in the second through hole 212 to avoid the extension protrusion 116 and the inner protrusion 2122 is inserted between the extension protrusion 116 and the buckle side wall 112, and the second avoidance groove 2124 can also be used to avoid the switch part 122 to prevent the switch part 122 from being pressed or squeezed, thereby solving the problem in the prior art that the switch part 122 and at least part of the second hollow part 114 are located on the same plane, resulting in the side wall of the second through hole 212 squeezing or pressing the switch part 122, and then squeezing or pressing the switch part 122 between the two buckle side walls 112.

[0098] Among them, after the first avoidance groove 2121 and the second avoidance groove 2124 are provided in the second through hole 212 of the present application, the second through hole 212 as a whole is a cross-shaped structure, so as to avoid the extending protrusion 116 and the switch part 122.

[0099] Furthermore, if Figure 6 As shown, the multiple through holes also include a third through hole 213, and the third through hole 213 includes two third avoidance grooves 2131, and the two third avoidance grooves 2131 are respectively opened on the two inner walls of the third through hole 213; wherein, after the hook body 21 is folded so that the multiple through holes are axially correspondingly arranged, the third avoidance grooves 2131 avoid the parts of the two switch parts 122 extending from the hole grooves of the buckle side wall 112.

[0100] The third through hole 213 is used to avoid the remaining portion of the switch portion 122 .

[0101] Specifically, the first through hole 211 is folded at the first part of the latch 11, the second through hole 212 is folded at the second part of the latch 11, and the third through hole 213 is folded at the middle part of the latch 11, and avoids the switch part 122 through the third avoidance groove 2131 to prevent the third through hole 213 from pressing the switch part 122.

[0102] More specifically, when the hook 20 and the buckle 10 are assembled and installed, the hook body 21 is folded so that the first through hole 211 is folded to the bottom, the second through hole 212 is folded to the top, and the third through hole 213 is folded between the first through hole 211 and the second through hole 212. Then, the buckle 11 is inserted into the first through hole 211, the third through hole 213 and the second through hole 212 in sequence, and the first protrusion 2111 of the first through hole 211 is inserted into the buckle 11. In the first hollow portion 113 of the fastener 11, the third avoidance groove 2131 of the third through hole 213 avoids the switch portion 122, and the first avoidance groove 2121 avoids the extension protrusion 116, so that the inner protrusion 2122 is inserted into the second hollow portion 114 and is clamped between the extension protrusion 116 and the buckle side wall 112, so that the fastener 11 is limited and cannot rotate under the action of the inner protrusion 2122, the first protrusion 2111, and the first avoidance groove 2121.

[0103] In some embodiments, two third through holes 213 may be provided to increase the thickness of the middle folded portion of the ear hook body 21 and avoid the switch portion 122 .

[0104] Furthermore, the ear hook body 21 also includes a first folding weakening line, which is arranged on the ear hook body 21 and located between the two third through holes 213, so as to facilitate folding of the ear hook body 21 so that the two third through holes 213 overlap, thereby increasing the thickness of the folded ear hook body 21.

[0105] Specifically, since the thickness of the middle portion of the buckle 11 is relatively long, at least two third through holes 213 can be provided so as to correspond to the middle portion of the buckle 11 and avoid the switch portion 122 after the ear hook body 21 is folded.

[0106] The first folding weakened line is used to facilitate folding of the ear hook body 21 and prevent a bulge from being formed at the folding line after the ear hook body 21 is folded.

[0107] Among them, the first folding weakening line can be a line hole structure.

[0108] In some of the embodiments, Figures 7-8 As shown, the ear hook body 21 is a double-layer structure to increase the thickness of the ear hook body 21 after being folded.

[0109] For example, the double-layer ear hook body 21 can be an integral structure, which can be folded left and right to increase the overall thickness of the ear hook body 21, thereby increasing the thickness of the first protrusion 2111 and the inner protrusion 2122 to increase the limiting ability of the buckle 11.

[0110] For another example, the double-layer ear hook body 21 may be formed by sewing two sub-pieces to form a double-layer structure.

[0111] Furthermore, there are two hanging ear bodies 21, which are mirror-imaged along the length direction of the hanging ear bodies 21. The two hanging ear bodies 21 are configured to overlap and fold along the symmetry axis of the two hanging ear bodies 21, so that multiple through holes on the two hanging ear bodies 21 overlap with each other.

[0112] The ear hook body 21 is provided with two parts, which are also used to increase the overall thickness of the ear hook body 21, so that the ear hook body 21 can completely cover the first hollow part 113 of the buckle 11, the middle part of the buckle 11 and at least part of the second hollow part 114 after being folded.

[0113] After the ear main bodies 21 are arranged in a mirror image, the two ear main bodies 21 can be folded along the symmetry axis, and then the two ear main bodies 21 can be folded synchronously to be sleeved on the buckle 11 .

[0114] Furthermore, a second folding weakened line 214 is provided at the symmetry axis of the two hanging ear bodies 21 to facilitate folding of the two hanging ear bodies 21 .

[0115] Preferably, the ear hook body 21 of the present invention is an integrated structure, and there are two ear hook bodies 21 and they are arranged as a mirror structure. At the same time, the ear hook body 21 is arranged as two pieces distributed on the left and right. When folding the ear hook body 21, the ear hook body 21 can be first folded left and right to form a two-layer structure, and then the ear hook body 21 is folded along the mirror symmetry axis so that the multiple through holes on the two ear hook bodies 21 are arranged one by one. The two ear hook bodies 21 are folded so that the first through hole 211 can correspond to the first hollow portion 113 of the buckle 11, the second through hole 212 can correspond to the second hollow portion 114, and the third through hole 213 can correspond to the middle part of the buckle side wall 112.

[0116] In some of the embodiments, the ear hook body 21 also includes a plurality of openings 215, which are arranged in the portion of the folded ear hook body 21 that is attached to the bottom panel 111, so as to allow the two side edges or four corners of the bottom panel 111 to enter, so as to hide the two side edges or four corners of the bottom panel 111 and avoid scratching the air curtain when the air curtain is unfolded.

[0117] The ear hook body 21 may be provided with two openings 215 arranged opposite to each other, so that after the buckle 11 is inserted into the folded ear hook body 21 , the two edges of the bottom panel 111 can be inserted into the two openings 215 to hide the metal corners of the bottom panel 111 .

[0118] The ear hook body 21 may be provided with four openings 215 , and after the buckle 11 is inserted into the folded ear hook body 21 , the four corners of the bottom panel 111 are inserted into the four openings 215 to hide the metal corners of the bottom panel 111 .

[0119] An air curtain connection structure of the present embodiment is aligned with the hole on the air curtain lug and sewn into one piece after assembly.

[0120] The long strip hanging ear described in the present invention has multiple through holes, and the first through hole of the multiple through holes has first protrusions at the upper and lower ends, and openings are provided on the left and right sides / four corners. The first protrusion is inserted into the first hollow part of the buckle. When the buckle has a tendency to rotate, the interference with the first protrusion and the side wall of the buckle is used to prevent the buckle from rotating, so as to achieve the limiting of the buckle. The metal parts on both sides or the four corners of the buckle can be loaded into the openings, which can assist in achieving the limiting of the buckle and wrap the sharp metal corners of the buckle to avoid hurting the loader and scratching the airbag when the airbag is deployed. The second through hole of the multiple through holes is obliquely provided with an inner convex part based on a cross structure, and the second avoidance groove arranged laterally avoids the plastic part of the buckle from pressing the switch part to prevent the plastic part from being pressed in. The inner convex part cooperates with the second hollow part of the metal part of the buckle. When the buckle has a tendency to rotate, the interference with the extended convex part of the buckle is used to prevent the buckle from rotating, so as to achieve the limiting of the buckle. The third through hole of the plurality of through holes is a simplified version of the second through hole, and has two third transverse avoidance grooves, and the third avoidance grooves avoid the snap-on plastic part pressing the switch to prevent the plastic part from being pressed in.

[0121] An air curtain connection structure of the present invention, such as Figures 7-8 As shown, the multiple through holes can be flexibly arranged according to the actual needs of different buckles, such as setting a first through hole or two second through holes, or setting a first through hole, a second through hole and a third through hole.

[0122] The long strip hanging ear with multiple through holes described in the present invention can be obtained directly by adjusting the existing round hole ear piece. On the one hand, it can replace the plastic anti-rotation clip, and also realize the limiting of the buckle and avoid the airbag being scratched, thereby saving material cost and labor cost, conforming to the trend of green environmental protection, and meeting the cost control needs of the enterprise. On the other hand, it avoids the exposure of the metal sharp corners of the buckle without increasing the material cost, preventing injuries to the loaders, fully meeting the high requirements of the main engine factory for production safety, and improving the competitiveness of the enterprise.

[0123] The ear piece of the present invention has the following structural features:

[0124] 1. There are multiple through holes for installing buckles on the long strip hanging ear. After folding the long strip hanging ear several times, align it with the lug on the airbag body and then sew it. The folded hanging ear is folded several times again to align the holes, and the buckle is installed in the through hole.

[0125] 2. The through hole on the hanging ear has a hole groove, a protrusion and a clamping part. The hole groove avoids the plastic part from pressing the switch to prevent the plastic part from being pressed in. The protrusion and the clamping part are installed in the hollow part of the buckle. When the buckle tends to rotate, it interferes with the hard part of the buckle to prevent the buckle from rotating, thereby realizing the buckle limit.
