Description

Technical Field

[0001] The present invention relates to the technical field of safety airbags, and in particular to an airbag protection cover. Background Art

[0002] Airbags are a key restraint and protection device in passive safety systems. Normally, after being placed in the housing, the airbag is covered by a protective cover with a logo and a tear line. During a collision, the airbag deployment process breaks the tear line, causing the reversible portion of the airbag cover (the reversible portion is the part of the airbag cover that needs to be flipped after the tear line is torn after the airbag is deployed; some airbag covers also include a logo connected to the cover plate) to flip outward, allowing the airbag to break free of the cover.

[0003] In the prior art, airbag covers and logos are designed in a variety of styles. When the airbag is deployed, if the reversible portion / logo on the airbag cover is overweight, the reversible portion or logo may detach from the airbag cover and fly outward after being impacted by the airbag, which undoubtedly poses a potential danger to the driver.

[0004] Based on this, a new technical solution is needed. Summary of the Invention

[0005] In view of this, an embodiment of the present invention provides an airbag protection cover to at least solve the problem in the prior art that the flip-over portion and the logo of the existing airbag protection cover are easily scattered outward when the airbag is deployed.

[0018] Furthermore, the airbag protection cover further includes:

[0019] a covering portion, the covering portion being foldably connected to the first end of the first auxiliary belt, the covering portion being provided with a restraining hole;

[0020] When the first end of the first auxiliary belt is fixed to the connecting post, the covering portion is folded toward the direction of the connecting post, and the restraining hole is placed on the hook assembly to cover at least a portion of the connecting post.

[0021] Furthermore, when the connecting column is provided on the cover plate body and the connecting hole is provided on the logo, the first end of the auxiliary belt is provided between the logo and the cover plate body.

[0022] Furthermore, when the tear line passes through the logo and divides the logo into a first sub-portion and at least a second sub-portion, the first auxiliary belt pulls the first sub-portion through the connecting post, wherein the weight of the first sub-portion is greater than that of the second sub-portion.

[0023] Furthermore, there is at least one tear line to form at least two flip-over portions on the airbag protection cover, and the logo is located on at least one of the flip-over portions;

[0024] There are at least two first auxiliary belts, and the first through hole on each of the first auxiliary belts is arranged to cooperate with at least a portion of the connecting column on the corresponding flippable portion.

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

[0048] The following describes the embodiments 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.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of this 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 this 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 an apparatus and / or practice a method. In addition, other structures and / or functionalities other than one or more of the aspects described herein can be used to implement this apparatus 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 illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0051] Additionally, in the following description, specific details are provided to provide a thorough understanding of the examples, however, one skilled in the art will appreciate that the examples can be practiced without these specific details.

[0052] Existing airbag logos and covers are of various types, and a weakening line is set on the cover. After the front airbag is folded, it is usually placed in a receiving cavity on the steering wheel and covered by the cover. After the front airbag is released, the front airbag impacts the cover, causing the cover to tear along the weakening line. The flip-up part on the cover flips outward to allow the front airbag to rush out of the cover to protect the occupants.

[0053] Since the company logo is installed on the flip part of the cover, when the flip part is flipped by an impact, if the company logo is heavy, the company logo will cause the flip part to fly outward, which may easily cause injuries to the passengers in the car.

[0054] Based on this, this specification proposes a solution: Figure 1 As shown, an airbag protection cover of the present invention assembles and connects the cover body 10 and the logo 20 through the connecting column 30 and the connecting hole 40, and fixes the first end of the first auxiliary belt 50 to the connecting column 30 of the flippable part 11 in the cover body 10, so that when the flippable part 11 is flipped by the impact of the airbag, the first auxiliary belt 50 pulls the logo 20 and the flippable part 11 through the connecting column 30 to prevent the logo 20 and the flippable part 11 from flying outward, and the flippable part 11 can flip normally to allow the internal airbag to deploy.

[0055] The following describes the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0056] like Figures 1 to 5 As shown, an embodiment of the present invention provides an airbag protection cover, including a cover body 10 and a logo 20. The cover body 10 includes a reversible portion 11 and a tear line 12 arranged along the side of the reversible portion 11. The logo 20 is at least partially located on the reversible portion 11, and the cover body 10 and the logo 20 are assembled / hot-melt connected through a plurality of connecting columns 30 and a plurality of connecting holes 40.

[0057] Among them, when the cover body 10 covers the front airbag, if the front airbag is deployed, the front airbag will impact the flip-over part 11, causing the cover body 10 to split along the tear line 12. The flip-over part 11 can flip along the connection between itself and the cover body 10, and drive the logo 20 to flip.

[0058] In some embodiments, the logo 20 may be entirely disposed on the reversible portion 11 , and when the reversible portion 11 is reversed, the logo 20 is entirely reversed along with the reversible portion 11 .

[0059] In some embodiments, the logo 20 may be partially disposed on the reversible portion 11 , and when the reversible portion 11 is reversed, part of the logo 20 is reversed along with the reversible portion 11 .

[0060] For example, the logo 20 is provided with a tear line 12 or the logo 20 is provided in separate parts.

[0061] In some of these embodiments, Figure 2 As shown, a connecting column 30 can be provided on the cover body 10, and a connecting hole 40 can be provided on the logo 20. When installing the logo 20, the logo 20 is installed into the reserved space of the cover body 10 from the inside of the cover body 10 to the outside of the cover body 10, and the connecting column 30 is inserted into the corresponding connecting hole 40 to achieve the installation of the logo 20 on the cover body 10.

[0062] In some of these embodiments, Figure 3 As shown, a connecting hole 40 can be provided on the cover body 10, and a connecting column 30 can be provided on the logo 20. When installing the logo 20, the logo 20 is installed into the reserved space of the cover body 10 from the outside of the cover body 10 to the inside of the cover body 10, and the connecting column 30 is inserted into the corresponding connecting hole 40 to achieve the installation of the logo 20 on the cover body 10.

[0063] In some embodiments, the connecting post 30 is interference-connected with the connecting hole 40 . After the connecting post 30 is inserted into the connecting hole 40 , the logo 20 can be fixed to the cover body 10 .

[0064] For example, the end size of the connecting column 30 can be slightly larger than the size of the connecting hole 40. After the end of the connecting column 30 is forcibly pressed into the connecting hole 40, the end of the connecting column 30 can be limited to the connecting hole 40, and then the logo 20 can be limited to the cover body 10; or the end of the connecting column 30 is inserted into and passes over the connecting hole 40. At this time, since the end size of the connecting column 30 is slightly larger than the connecting hole 40, the end of the connecting column 30 will not easily detach from the connecting hole 40.

[0065] In some embodiments, the connecting post 30 and the connecting hole 40 form a snap-fit ​​connection to restrict the connecting post 30 within the connecting hole 40 .

[0066] In some embodiments, when the outer diameter of the connecting column 30 is smaller than the inner diameter of the connecting hole 40 , after the connecting column 30 is inserted into the connecting hole 40 , the connecting column 30 is fixed to the connecting hole 40 by hot melting to fix the logo 20 to the cover body 10 .

[0067] Preferably, the connecting pillars 30 are fixed in the corresponding connecting holes 40 by hot melting to reduce the difficulty of production.

[0068] like Figure 1 、 6 As shown, the airbag protection cover also includes a first auxiliary belt 50, and the first end of the first auxiliary belt 50 is provided with at least one first through hole 51, and the at least one first through hole 51 is cooperated and connected with at least part of the connecting column 30 on the flippable part 11, and the second end of the first auxiliary belt 50 is connected to the bottom end of the cover body 10, the gas generator and at least one of the airbags.

[0069] Among them, after the first through hole 51 is correspondingly sleeved on the connecting column 30, the first end of the first auxiliary belt 50 is fixed on the connecting column 30 to pull the reversible part 11 and the logo 20 when the reversible part 11 and the logo 20 are flipped by the impact of the airbag, so as to prevent the reversible part 11 and the logo 20 from flying outward.

[0070] The first auxiliary belt 50 is made of cloth.

[0071] In some embodiments, when a connecting column 30 is provided on the cover body 10 and a connecting hole 40 is provided on the logo 20, the first end of the first auxiliary belt 50 can be provided between the logo 20 and the cover body 10, or the first end of the first auxiliary belt 50 can be provided on the side of the logo 20 away from the cover body 10.

[0072] Preferably, the first end of the first auxiliary belt 50 is disposed between the logo 20 and the cover plate body 10 to prevent the first auxiliary belt 50 from being separated from the connecting post 30 .

[0073] Specifically, when the connecting columns 30 are arranged on the cover plate body 10 and the connecting holes 40 are arranged on the marker 20, first, the first through holes 51 of the first auxiliary band 50 are sleeved on the corresponding connecting columns 30, then the marker 20 is installed on the cover plate body 10 from the inside of the cover plate body 10 to the outside of the cover plate body 10, and the connecting holes 40 are sleeved on the connecting columns 30, so that the first end of the first auxiliary band 50 is limited between the marker 20 and the cover plate body 10.

[0074] In some embodiments, when the connecting holes 40 are arranged on the cover plate body 10 and the connecting columns 30 are arranged on the marker 20, after the marker 20 is assembled with the cover plate body 10 through the connecting columns 30 and the connecting holes 40, the first through holes 51 are sleeved on the connecting columns 30, and finally the connecting columns 30 are heat-fused, so as to limit the first end of the first auxiliary band 50 to the connecting columns 30.

[0075] Preferably, the number of the first through holes 51 is multiple, so that the multiple first through holes 51 are sleeved on the multiple connecting columns 30 on the reversible part 11, so as to increase the firmness of the connection between the first end of the first auxiliary band 50 and the connecting columns 30.

[0076] In the embodiment, the number of the first through holes 51 is equal to the number of the connecting columns 30 on the reversible part 11, so as to increase the pulling capacity of the first auxiliary band 50 to the reversible part 11.

[0077] In the embodiment, the size of the first through holes 51 is equal to, slightly larger than or slightly smaller than the size of the connecting columns 30, so as to limit the first auxiliary band 50 to the connecting columns 30.

[0078] In the embodiment, when the size of the first through holes 51 is equal to or slightly larger than the size of the connecting columns 30, the connecting columns 30 can be inserted into the first through holes 51.

[0079] In the embodiment, when the size of the first through holes 51 is slightly smaller than the size of the connecting columns 30, the connecting columns 30 can still be inserted into the first through holes 51 due to the elasticity of the cloth, and the connecting columns 30 cannot be easily separated from the first through holes 51 after being inserted into the first through holes 51, so as to preliminarily fix the first end of the first auxiliary band 50 to the connecting columns 30.

[0080] In some embodiments, when the cover plate body 10 has two reversible parts 11 through the tearing lines 12, if the marker 20 is completely located on one of the reversible parts 11, the first through holes 51 on the first auxiliary band 50 are sleeved on the connecting columns 30 on the reversible part 11 with the marker 20, so as to pull the reversible part 11 and the marker 20, and avoid the scattering of the reversible part 11 and the marker 20.

[0081] In some embodiments, when the tear line 12 passes through the logo 20 and divides the logo 20 into a first sub-portion and at least a second sub-portion, the first auxiliary belt 50 pulls the first sub-portion through the connecting post 30, wherein the first sub-portion is heavier than the second sub-portion.

[0082] Among them, since the heavier the logo 20 and the flip-up part 11 are, the greater the probability that the logo 20 and the flip-up part 11 will fly outward after being impacted by the airbag, it is necessary to connect the first auxiliary belt 50 to the heavier first sub-part to avoid the heavier first sub-part from flying outward after being impacted by the airbag.

[0083] In some embodiments, when the logo 20 is a split structure, the first auxiliary belt 50 pulls the heavier split logo 20 through the corresponding connecting post 30 .

[0084] In some embodiments, when the first end of the first auxiliary band 50 is fixed to the connecting post 30 on the cover body 10 / logo 20, a felt can be used to cover the first end of the first auxiliary band 50 to prevent the connecting post 30 from flying around after being broken by the hot-melt portion.

[0085] In the embodiment of the present invention, the first end of the first auxiliary belt 50 is fixed to the connecting column 30 on the cover body 10 / logo 20, so that the flip portion 11 and the logo 20 can be pulled well, thereby preventing the flip portion 11 and the logo 20 from flying outward when the airbag protection cover is impacted by the airbag.

[0086] Furthermore, when the first end of the first auxiliary belt 50 is connected to the bottom end of the cover body 10, the second end of the first auxiliary belt 50 is located on the side of the flip axis of the flip part 11 away from the flip part 11, so that the first end of the first auxiliary belt 50 is connected to the flip part 11, and the second end is connected to the non-flip part of the cover body 10, thereby realizing the pulling effect of the first auxiliary belt 50 on the flip part 11 and the logo 20.

[0087] When the second end of the first auxiliary belt 50 is connected to the bottom end of the cover plate body 10 , it can be connected to the cover plate body 10 by bolts.

[0088] When the second end of the first auxiliary belt 50 is connected to the gas generator, the second end of the first auxiliary belt 50 can be fixed to the gas generator by means of bolts on the gas generator.

[0089] When the second end of the first auxiliary belt 50 is connected to the airbag, it can be sewn to the bottom of the airbag.

[0090] In some of these embodiments, Figures 6 to 7As shown, the first auxiliary belt 50 also includes a first weakening structure 60, which is arranged at the second end of the first auxiliary belt 50 and is located on the side of the multiple first through holes 51 away from the first end of the first auxiliary belt 50. It is used to at least partially break when the first auxiliary belt 50 is subjected to force, so as to absorb the impact energy received by the first auxiliary belt 50.

[0091] Specifically, when the airbag under the cover body 10 is deployed, the flippable part 11 flips over and causes the first auxiliary belt 50 to be impacted. At this time, the first weakening structure 60 can be disconnected or partially disconnected to absorb the impact energy received by the first auxiliary belt 50, so as to avoid the first end of the first auxiliary belt 50 from being separated from the connecting column 30 or the second end of the first auxiliary belt 50 from being separated from the bottom end of the cover body 10, the gas generator or the airbag; and since the first auxiliary belt 50 absorbs part of the energy after being disconnected, it can also effectively reduce or avoid the flippable part 11 from being disconnected at the flipping axis, causing the flippable part 11 and the logo 20 to fly outward.

[0092] The first weakened structure 60 may be a weakened structure composed of a plurality of weakened holes; the width of the first weakened structure 60 may also be set to be smaller than the overall width of the first auxiliary belt 50 .

[0093] Among them, when the first weakening structure 60 is partially broken, it can initially absorb the impact energy received by the first auxiliary belt 50 and can still maintain the pulling effect on the reversible part 11 until the first weakening structure 60 absorbs enough impact energy and breaks completely. At this time, the impact energy received by the reversible part 11 is reduced, thereby reducing the probability of the reversible part 11 flying outward.

[0094] like Figures 6 to 7 As shown, the first weakening structure 60 includes a weakening portion 61 and a stretching portion 62 . Both the weakening portion 61 and the stretching portion 62 are provided on the first auxiliary belt 50 to absorb the impact energy received by the first auxiliary belt 50 when impacted.

[0095] The weakened portion 61 and the stretched portion 62 are both provided on one side of the first auxiliary belt 50 , and the strength of the weakened portion 61 is smaller than the strength of the stretched portion 62 .

[0096] The weakened portion 61 may be a weakened structure composed of a plurality of weakened holes, or may be formed by cutting off one side of the first auxiliary belt 50 and sewing it with a thread of relatively low strength.

[0097] The stretching portion 62 may be made of an elastic fabric, such as an elastic band.

[0098] Specifically, when the first auxiliary belt 50 is impacted, the weakened portion 61 and the stretching portion 62 are stretched at the same time. At this time, the stretching portion 62 is stretched, thereby alleviating the tension on the weakened portion 61 and maintaining the weakened portion 61 from being torn, while absorbing part of the energy; when the stretching portion 62 is stretched to the extreme, the weakened portion 61 continues to absorb the impact energy received by the first auxiliary belt 50 until the weakened portion 61 breaks.

[0099] The present invention uses the stretching portion 62 and the weakening portion 61 to gradually absorb the impact energy received by the first auxiliary belt 50, thereby making the force curve of the reversible portion 11 smoother, and avoiding the situation where the weakening portion 61 is instantly disconnected when the impact energy is too large, causing the reversible portion 11 to instantly flip over and scatter outward.

[0100] In some of these embodiments, Figures 6 to 8 As shown, the logo 20 further includes a hook assembly 21, and the first auxiliary belt 50 further includes a pre-installed hole 52. The hook assembly 21 is disposed on the inner surface of the logo 20; the pre-installed hole 52 is formed at the first end of the first auxiliary belt 50 and engages with the hook assembly 21, allowing the first end of the first auxiliary belt 50 to be pre-installed on the logo 20, thereby facilitating the first through-hole 51 to be fitted over the connecting post 30.

[0101] Among them, when a pre-installed hole 52 is opened at the first end of the first auxiliary belt 50 to cooperate with the hook component 21, the first through hole 51 on the first auxiliary belt 50 is put on the connecting column 30 after the connecting column 30 is inserted into the connecting hole 40.

[0102] The hook assembly 21 can be integrally cast with the logo 20 or installed on the logo 20 later.

[0103] The pre-installed hole 52 is a hole structure opened at the first end of the first auxiliary belt 50 , and is used to preliminarily position the first end of the first auxiliary belt 50 on the logo 20 when the first through hole 51 is not inserted into the connecting hole 40 .

[0104] In some of these embodiments, Figure 7 As shown, the airbag protection cover also includes a covering portion 70, which can be folded and connected to the first end of the first auxiliary belt 50, and a restraining hole 71 is opened on the covering portion 70, which is used to cooperate with the hook component 21 to limit the covering portion 70 to below the first auxiliary belt 50.

[0105] The covering portion 70 is used to block the scattered hot melt blocks of the connecting post 30 when the hot melt point of the connecting post 30 is destroyed, thereby preventing the hot melt blocks of the connecting post 30 from injuring the occupants.

[0106] When the first end of the first auxiliary belt 50 is fixed to the connecting post 30 , the covering portion 70 is folded toward the connecting post 30 and the restraining hole 71 is placed on the hook assembly 21 to cover at least part of the connecting post 30 .

[0107] Preferably, the covering portion 70 can cover all the connecting pillars 30 .

[0108] Among them, since the connecting column 30 is hot-melted and fixed in the connecting hole 40, if the flip-up part 11 is impacted, the hot-melted part of the connecting column 30 may break under the pulling of the first auxiliary belt 50. Therefore, after the covering part 70 covers the connecting column 30, the covering part 70 can prevent the hot-melted part of the connecting column 30 from flying outward, so as to protect the occupants as much as possible.

[0109] The covering portion 70 may be made of cloth.

[0110] A folding portion may be provided between the covering portion 70 and the first end of the first auxiliary belt 50 , so that the covering portion 70 is folded along the folding portion and covers the connecting column 30 .

[0111] The folding portion may be provided along the tear line 12 or along the edge of the logo 20 .

[0112] The covering portion 70 may be a cloth structure or a ring structure.

[0113] In some of these embodiments, Figure 9 There is at least one tear line 12 on the cover plate body 10 , so as to form at least two reversible portions 11 on the cover plate body 10 . In this case, the logo 20 is located on at least one of the reversible portions 11 .

[0114] When there are at least two reversible parts 11, there are at least two first auxiliary belts 50, and the first through holes 51 on each first auxiliary belt 50 are matched with at least part of the connecting column 30 on the corresponding reversible part 11 to pull the multiple reversible parts 11 respectively.
