Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of automobile parts manufacturing, and in particular to a side air curtain guide bracket and a vehicle. Background Art

[0002] As cars become more and more popular, consumers are paying more attention to their safety performance. In road traffic accidents, vehicles may have various forms of accidents, including head-on collision, rear-end collision, side collision, rollover, etc. The impact of the head in a side collision accident often causes fatal injuries. Side airbags are safety devices specifically designed for head protection. They can effectively prevent occupants from suffering head injuries or reduce the extent of their injuries in side collision accidents, and have gradually become a standard configuration for vehicle safety systems. At the same time, the evaluation criteria for side airbags are more stringent, and stricter requirements are put forward for their layout structure, deployment form, protection area, protection effect, etc.

[0003] Side air curtains are usually installed on the inner plate of the upper side beam of the vehicle body side. After they are exploded and ejected, they generally need to pass through the guide limit of the guide bracket to accurately eject to the predetermined position to achieve the purpose of protecting passengers. Traditional side air curtain guide brackets generally have two forms: one is a sheet metal structure, which is designed by welding or screwing the guide bracket on the upper side beam of the vehicle body side; the other is a plastic structure, which is designed by integrating the plastic bracket structure on the interior trim and installed on the upper side beam of the vehicle body side.

[0004] However, the above traditional side air curtain guide brackets have the following shortcomings, such as the sheet metal structure bracket needs to develop tooling fixtures for welding process or use standard parts for assembly and screw connection, which is costly; the plastic structure will increase the complexity of interior trim design, and the mold cost will increase higher than the sheet metal design cost. As a result, the traditional guide bracket has many shortcomings such as complex installation structure, inconvenient disassembly and high cost. Summary of the invention

[0005] In view of this, the embodiments of the present application provide a side air curtain guide bracket and a vehicle, which have the advantages of simple installation structure, easy disassembly and low cost.

[0006] To achieve the above-mentioned purpose, the first aspect of the embodiment of the present application provides a side air curtain guide bracket, which is fixed on the inner plate of the upper side beam of the vehicle, and the side air curtain guide bracket includes a side air curtain mounting portion, a guide portion and a first clamping portion. The side air curtain mounting portion is used to mount the side air curtain; the guide portion is arranged on the side air curtain mounting portion and extends along the first direction, and is used to guide the side air curtain to pop out along the extending direction of the guide portion; the first clamping portion is arranged on the side of the guide portion away from the side air curtain mounting portion, and is used to clamp with the second clamping portion of the inner plate of the upper side beam.

[0007] Specifically, the side air curtain installation part is used to install the side air curtain. When the side air curtain explodes and pops out, since the guide part is arranged in the pop-out direction of the side air curtain, the side air curtain can be guided to unfold along the plane where the guide part is located, thereby protecting the occupants. Among them, since the first clamping part is arranged on the side of the guide part away from the side air curtain, that is, the side of the side air curtain not in contact with the guide part, it can be prevented that the first clamping part scratches or damages the side air curtain when the side air curtain is unfolded, and affects the normal unfolding of the side air curtain. Here, since the guide bracket and the upper side beam inner plate are clamped together by the first clamping part and the second clamping part, compared with the related art in which the upper side beam inner plate is provided with a threaded hole, the guide bracket is provided with a mounting through hole, and the guide bracket is threadedly connected to the inner plate of the connecting beam on the body by screws that cooperate with the threaded holes, it has high installation efficiency and low assembly cost, is not easy to loosen under alternating loads, and does not require high hole making accuracy like threaded connection; in addition, there is also a design in the related art that integrates the plastic structure guide bracket into the interior trim panel and then installs it on the body side beam, but it will increase the complexity of the interior trim panel design, thereby greatly increasing the mold development cost of the interior trim panel, and the plastic structure guide bracket has a difficult to ensure structural strength and poor heat resistance. In summary, the design of the guide bracket of the present application being clamped together with the upper connecting beam inner plate makes the guide bracket installation method simple and easy, with low installation cost and easy disassembly.

[0008] Here, the specific structural form of the first clamping part and the second clamping part is not limited. For example, the first clamping part may be provided with a clamping protrusion, and the second clamping part may be provided with a clamping groove matching with the clamping protrusion, and the clamping protrusion may fit into the clamping groove and engage in a limited position to realize the clamping of the guide bracket and the inner plate of the upper connecting beam; or the first clamping part may be provided with a clamping groove, and the second clamping part may be provided with a clamping protrusion matching with the clamping groove, and the clamping protrusion of the second clamping part may extend into the clamping groove of the first clamping part for clamping.

[0009] In a possible implementation of the present application, the second clamping portion is a clamping hole, and there are two clamping holes, namely a first clamping hole and a second clamping hole. The first clamping portion includes a first sub-clamping portion and a second sub-clamping portion. The first sub-clamping portion is clamped with the first clamping hole, and the second sub-clamping portion is clamped with the second clamping hole. Here, the two clamping holes correspond to the settings of the two clamping portions, respectively, which can improve the stability of the guide bracket clamped on the inner plate of the upper side beam.

[0010] In a possible implementation of the present application, the first sub-clamping portion has a first limiter, the guide portion is a guide plate, the guide plate extends along the first direction, the first limiter is arranged at the rear end of the guide plate, and the first limiter is used to limit the movement of the fixed guide bracket along the first direction. When the guide bracket is clamped with the inner plate of the upper side beam, if the guide bracket in the clamping hole is not further limited, the guide bracket may move relative to the inner plate of the upper side beam, thereby affecting the guidance of the guide portion of the guide bracket to the side air curtain, causing a large deviation in the pop-up direction of the side air curtain, or there is a risk that the guide bracket will be separated from the inner plate of the upper side beam.

[0011] Therefore, it is necessary to limit and fix the guide bracket in three-dimensional space, especially to limit and fix the guide bracket along the pop-up direction of the side air curtain. By providing a first limiter on the guide portion, the guide bracket can be fixed and limited in the first direction to improve the stability of the connection between the guide bracket and the inner plate of the upper side beam.

[0012] In a possible implementation of the present application, the guide portion includes a stop protrusion and a flange, the stop protrusion abuts against the hole wall of the upper side beam inner plate, and the flange direction of the flange faces the first direction; after the flange passes through the upper side beam inner plate, it fits against a side wall of the upper side beam inner plate away from the side air curtain. For example, the upper side beam inner plate is provided with a through hole, the flange and the stop protrusion are relatively arranged on the same side of the guide portion, and after the flange passes through the through hole, it fits against the side wall of the upper side beam inner plate away from the side air curtain, and the stop protrusion abuts against at least part of the hole wall of the through hole. In this way, not only the guide bracket is limited in the first direction, but the flange design can also improve the stability of the connection between the guide bracket and the upper side beam inner plate.

[0013] In a possible implementation of the present application, the guide plate has an opening, and the hole wall on the side of the opening close to the inner plate of the upper side beam has an extension plate parallel to the first direction, and the second sub-clamping portion is a second limiting member, and the second limiting member includes a limiting plate, and the limiting plate is connected to the free end of the extension plate, and the limiting plate is located on the side of the guide plate away from the side air curtain, and the limiting plate can be extended into the second clamping hole, and is used to limit the guide bracket in the second direction; the second direction is perpendicular to the first direction and parallel to the plane where the guide plate is located. With such a design, the movement of the guide bracket in the first clamping hole along the second direction can be limited, and the stability of the guide bracket clamped on the inner plate of the upper side beam can be further ensured.

[0014] In a possible implementation of the present application, along the second direction, there are gaps between the two sides of the limit plate and the corresponding two side hole walls of the second clamping hole, which enable the guide bracket to move within the gap. Here, although the guide bracket has a certain range of motion along the second direction, the plane where the guide plate of the guide bracket is located does not change during the movement of the guide bracket along the second direction, that is, the guide surface of the side air curtain does not change, that is, it does not affect the ejection direction of the side air curtain. With such a configuration, the guide bracket can be moved along the second direction to facilitate the removal of the guide bracket.

[0015] In a possible implementation of the present application, the plane where the limit plate is located has an angle with the plane where the guide plate is located, and the limit plate extends out of the second clamping hole, so that the second sub-clamping portion of the guide bracket can be inserted into the second clamping hole.

[0016] In a possible implementation of the present application, the lower surface of the limit plate has a folding plate, the plane where the folding plate is located is parallel to the second direction, the free end of the folding plate faces the guide plate and is arranged obliquely downward, and along the third direction, the second clamping hole of the folding plate is interference fit, and the third direction is perpendicular to both the first direction and the second direction. If the guide plate moves along the third direction, the angle between the plane where the guide plate is located and the vertical direction will change, which will have a greater impact on the preset pop-up direction of the side air curtain. Therefore, it is necessary to strictly control the movement of the guide plate along the third direction. The method of extending the folding plate into the second clamping hole and having an interference fit therewith realizes the strict clamping limit of the guide plate along the third direction, that is, further improves the reliability of the clamping between the guide bracket and the inner plate of the upper side beam.

[0017] In a possible implementation of the present application, the guide bracket is made of metal and is an integrally formed structure. Here, compared with the guide bracket made of plastic, the guide bracket made of metal has high strength, is not easy to deform, and has high reliability. The metal integrally formed design has a simple structure, high production efficiency, and strong stability.

[0018] The second aspect of the embodiment of the present application provides a vehicle, which includes an upper side beam inner plate, a side air curtain, and a guide bracket of any one of the first aspects. Among them, the vehicle body has a second clamping portion on the upper side beam inner plate; the side air curtain includes a side air curtain body and a side air curtain body connecting portion, and the side air curtain is connected to the side air curtain mounting portion through the connecting portion; the first clamping portion on the guide bracket is clamped with the second clamping portion to detachably connect the guide bracket to the upper side beam inner plate. Such a design, compared with the guide bracket being welded, screwed or integrated with the upper side beam inner plate, the guide bracket installation structure is simple, detachable, and has a low manufacturing cost, which helps to improve the vehicle production efficiency and reduce the manufacturing and maintenance costs of the vehicle.

Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

[0034] The present application embodiment provides a vehicle, referring to Figure 1 and Figure 3 , including an upper side beam inner plate 2, a side air curtain 3 and a guide bracket 1. Here, since the side air curtain 3 can effectively reduce the degree of injury to the occupants when responding to a side collision of the vehicle, the side air curtain 3 is widely used in the active safety of the vehicle. Among them, the vehicle is usually also equipped with a side collision sensor and an airbag controller assembly, a gas generator matched with the side air curtain 3 and its fixing bracket, etc.

[0035] For example, when the vehicle is hit from the side or rolls over, the side collision sensor receives the corresponding side collision signal and transmits it to the airbag controller assembly. The airbag controller assembly analyzes and calculates the signal strength and determines whether and when the airbag system should be detonated based on the results of the vehicle airbag calibration program. When the gas is detonated, a large amount of gas generated is quickly filled into the airbag cavity through the guide plate and the airway. The continuously inflated side air curtain 3 pops out along the guide bracket 1 and unfolds to form an air bag in the shape of a curtain, covering the side surrounding area. The inflated side air curtain 3 can prevent the head of the occupant on the outside of the seat from directly contacting and colliding with the window frame, hard interior or external intrusions at the moment of a traffic accident, thereby reducing the occupant's head injury.

[0036] Specifically, a vehicle provided in an embodiment of the present application, referring to Figure 1 , Figure 2 and Figure 3 The invention comprises an upper side beam inner plate 2, a side air curtain 3 and a guide bracket 1. The vehicle body has a second clamping portion 21 on the side beam inner plate 2; the side air curtain 3 comprises a side air curtain body 31 and a connecting portion 32 on the side air curtain body 31, and the side air curtain 3 is connected to the side air curtain mounting portion 12 through the connecting portion 32; the first clamping portion 11 on the guide bracket 1 is clamped with the second clamping portion 21 to detachably connect the guide bracket 1 to the upper side beam inner plate 2. Compared with the related art in which the guide bracket is threadedly connected to the inner plate of the connecting beam on the vehicle body, such a design has high installation efficiency and low assembly cost, is not easy to loosen under alternating loads, and does not require high hole making accuracy like threaded connection; in addition, there is also a design in the related art in which the guide bracket of the plastic structure is integrated into the interior trim panel and then installed on the side beam of the vehicle body, but it will increase the complexity of the interior trim panel design, thereby greatly increasing the mold development cost of the interior trim panel, and the structural strength of the guide bracket of the plastic structure is difficult to ensure and has poor heat resistance. Therefore, the installation structure of the guide bracket 1 of the present application is simple, reliable, detachable, and saves tooling costs and standard parts manufacturing costs, thereby helping to improve vehicle production efficiency and reduce vehicle manufacturing and maintenance costs.

[0037] It should be noted that the specific structural form of the side air curtain installation part 12 is not limited. For example, the side air curtain installation part 12 is a columnar protrusion, and the extension direction of the columnar protrusion is perpendicular to the plane where the guide part 13 is located. The side air curtain body 31 is located below the columnar protrusion and is in contact with the plane where the guide part 13 is located. The side air curtain body 31 has a connecting part 32 connected to the side air curtain 3 above. Here, the specific structural form of the connecting part 32 is also not limited. For example, it can be a mounting hole that matches the columnar protrusion. The columnar protrusion passes through the mounting hole on the side air curtain 3 to hang the side air curtain body 31 on the guide bracket 1. In order to prevent the side air curtain 3 from detaching from the side air curtain installation part 12, a limiting device can be provided on the free end of the columnar protrusion to prevent the side air curtain 3 from falling off the side air curtain installation part 12. Alternatively, the side air curtain installation part 12 on the guide bracket 1 and the connecting part 32 on the side air curtain 3 are a clamping structure, a screw structure, an adhesive structure, etc., which will not be repeated here.

[0038] The present application embodiment provides a side air curtain guide bracket 1, referring to Figure 1 , Figure 3 and Figure 7 , fixed on the inner plate of the upper side beam of the vehicle, the side air curtain guide bracket 1 includes a side air curtain installation portion 12, a guide portion 13 and a first clamping portion 11. Among them, the side air curtain installation portion 12 is used to install the side air curtain 3; the guide portion 13 is arranged along the side air curtain installation portion 12 and extends along the first direction, and is used to guide the side air curtain 3 to pop out along the extending direction of the guide portion 13; the first clamping portion 11 is arranged on the side of the guide portion 13 away from the side air curtain installation portion 12, and is used to clamp with the second clamping portion 21 of the inner plate of the upper side beam 2.

[0039] Specifically, the side air curtain installation part 12 is used to install the side air curtain 3. Since the guide part 13 is arranged on the side air curtain installation part 12 and extends along the first direction, wherein the first direction is the ejection direction of the side air curtain 3, when the side air curtain 3 explodes and ejects, the guide part 13 can guide the side air curtain 3 to eject along the first direction, that is, to unfold along the plane where the guide part 13 is located, so that the guide part 13 plays a guiding role when the side air curtain 3 ejects, thereby playing an effect of protecting the occupant. Among them, since the first clamping part 11 is arranged on the side of the guide part 13 away from the side air curtain 3, that is, the side of the side air curtain 3 not in contact with the guide part 13, thus, it can be prevented that the first clamping part 11 scratches or scratches the side air curtain 3 when the side air curtain 3 is unfolded and affects the normal unfolding of the side air curtain 3. In addition, since the guide bracket 1 and the upper side beam inner plate 2 are clamped by the first clamping part 11 and the second clamping part 21, the installation method of the guide bracket 1 is simple and easy, and it is convenient to disassemble and maintain.

[0040] Here, the specific structural form of the first clamping portion 11 and the second clamping portion 21 is not limited. For example, the first clamping portion 11 may be provided with a clamping protrusion, and the second clamping portion 21 may be provided with a clamping groove matching the clamping protrusion, and the clamping protrusion may fit into the clamping groove and engage in a limited position to achieve the clamping of the guide bracket 1 and the upper side beam inner plate 2; or the first clamping portion 11 may be provided with a clamping groove, and the second clamping portion 21 may be provided with a clamping protrusion matching the clamping groove, and the clamping protrusion of the second clamping portion 21 may extend into the clamping groove of the first clamping portion 11 for clamping.

[0041] It should be noted that there can be multiple side air curtain guide brackets 1, and the specific number is not limited. When there are multiple guide brackets 1, the number of corresponding clamping holes on the upper side beam inner plate 2 is also multiple. Multiple guide brackets 1 are distributed at intervals on the upper side beam inner plate 2 of the vehicle body, and the extension length of the guide portion 13 of the guide bracket 1 and the preset angle of the guide surface can be pre-designed according to the required pop-up direction of the side air curtain 3 to guide the side air curtain 3 to pop out along the preset direction. Among them, the side of the guide bracket 1 facing the side air curtain 3 is smoothed to prevent the sharp edge of the guide bracket 1 from scratching or breaking the side air curtain 3 when the side air curtain 3 explodes and expands.

[0042] In addition, the guide bracket 1 can be installed at any position on the upper side beam inner plate 2, as long as it is located below the side air curtain 3 so that the guide portion 13 faces the side air curtain 3. Preferably, the guide bracket 1 is installed at a position on the upper side beam inner plate 2 where the area is larger and flatter.

[0043] In some embodiments, reference Figure 1 and Figure 2 The second clamping portion 21 is a clamping hole, and there are two clamping holes, namely a first clamping hole 211 and a second clamping hole 212. The first clamping portion 11 includes a first sub-clamping portion 111 and a second sub-clamping portion 112. The first sub-clamping portion 111 is clamped with the first clamping hole 211, and the second sub-clamping portion 112 is clamped with the second clamping hole 212. Here, the two clamping holes correspond to the arrangement of the two clamping portions, respectively, which can improve the stability of the guide bracket 1 being clamped on the upper side beam inner plate 2.

[0044] Here, preferably, the clamping hole is a square hole. With this design, compared with circular, elliptical, or triangular clamping holes, the contact surface between the clamping portion and the clamping hole is larger, thereby improving the clamping stability.

[0045] In some embodiments, reference Figure 2 , Figure 5 , Figure 6 and Figure 7The first sub-clamping portion 111 is a first stopper, the guide portion 13 is a guide plate, the guide plate extends along the first direction, the first stopper is arranged at the tail end of the guide plate, and the first stopper on the guide portion 13 includes a stop protrusion 1111 and a flange 1112. For example, referring to Figure 2 , Figure 5 and Figure 6 The upper side beam inner plate 2 has a first clamping hole 211, the stopper protrusion 1111 and the flange 1112 are relatively arranged on the same side of the guide portion 13, the stopper protrusion 1111 abuts against the hole wall of the first clamping hole 211 near the upper side beam inner plate 2, the flange 1112 is flanged in the first direction, and the first direction is the pop-up direction of the side air curtain 3; the flange 1112 fits with the side wall of the guide portion 13 away from the side air curtain 3 after passing through the first clamping hole 211, and the first limiter is used to limit the movement of the guide bracket 1 in the first direction. When the guide bracket 1 is clamped with the upper side beam inner plate 2, if the guide bracket 1 in the clamping hole is not further limited, the guide bracket 1 may move relative to the upper side beam inner plate 2, thereby affecting the guidance of the guide portion 13 of the guide bracket 1 to the side air curtain 3, so that the pop-up direction of the side air curtain 3 deviates greatly from the preset pop-up direction, or there is a risk that the guide bracket 1 is separated from the upper side beam inner plate 2.

[0046] Therefore, it is necessary to limit and fix the guide bracket 1 in three-dimensional space, especially to strictly limit and fix the guide bracket 1 along the pop-up direction of the side air curtain 3. By arranging a first limiter on the guide plate, the stop protrusion 1111 of the first limiter abuts against the hole wall of the first clamping hole 211 close to the side wall of the upper side beam inner plate 2, and the flange 1112 on the first limiter fits against the side wall of the guide plate away from the side air curtain 3 after passing through the first clamping hole 211, and the direction of the flange 1112 faces the first direction, wherein the bent portion of the flange 1112 abuts against the hole wall of the second clamping hole 212 away from the side wall of the upper side beam inner plate 2, so that the guide bracket 1 can be fixed and limited in the first direction to improve the stability of the clamping of the guide bracket 1 and the upper side beam inner plate 2. Here, the specific structural form of the stop protrusion 1111 is not limited. For example, the end surface of the stop protrusion 1111 close to the upper side wall of the first clamping hole 211 is horizontally arranged, which can increase the contact area between the stop protrusion 1111 and the upper side wall of the first clamping hole 211, thereby improving the stability of the guide bracket 1 limited in the first direction. In addition, after passing through the first clamping hole 211, the flange 1112 is tightly fitted with the side wall of the guide plate away from the side air curtain 3, that is, zero fit, which can further improve the stability of the clamping between the guide bracket 1 and the upper side beam inner plate 2.

[0047] Continue, refer to Figure 2 , Figure 5 and Figure 6, the guide plate has an opening 131. Here, the setting of the opening 131 is convenient for setting the second sub-clamping portion 112 on the side of the guide plate away from the side air curtain 3, and can save the material cost of the guide bracket 1. Continuing, the hole wall of the opening 131 close to the side of the upper side beam inner plate 2 is provided with an extension plate 132 parallel to the first direction. The second sub-clamping portion 112 is a second limiting member, and the second limiting member includes a limiting plate 1121. The limiting plate 1121 is connected to the free end of the extension plate 132. The limiting plate 1121 is located on the side of the guide plate away from the side air curtain 3. The limiting plate 1121 can extend into the second clamping hole 212 to limit the guide bracket 1 in the second direction; the second direction is perpendicular to the first direction and parallel to the plane where the guide plate is located. With such a design, the movement of the guide bracket 1 in the first clamping hole 211 along the second direction can be limited, and the stability of the guide bracket 1 clamped on the upper side beam inner plate 2 can be further ensured.

[0048] It should be noted that the extension length of the limiting plate 1121 along the second direction is not limited, and its shape is not limited either. Its extension length is less than the minimum distance between the two hole walls of the second clamping hole 212 in the second direction, that is, the limiting plate 1121 can be extended into the second clamping hole 212. Preferably, the limiting plate 1121 adopts a square limiting plate 1121 with a regular shape and easy processing. In addition, the connection between the limiting plate 1121 and the free end of the extension plate 132 can adopt an integrated molding structure, which has strong overall reliability and low manufacturing cost compared to welding, clamping, etc.

[0049] In some embodiments, reference Figure 1 , Figure 2 and Figure 5 In the second direction, there are gaps between the two sides of the limiting plate 1121 and the corresponding two side hole walls of the second clamping hole 212, which enable the guide bracket 1 to move in the gap. Here, although the guide bracket 1 has a certain range of motion in the second direction, the plane where the guide plate of the guide bracket 1 is located does not change during the movement of the guide bracket 1 in the second direction, that is, the guide surface of the side air curtain 3 does not change, that is, it does not affect the ejection direction of the side air curtain 3. With this arrangement, the guide bracket 1 can be moved in the second direction to facilitate the removal of the guide bracket 1.

[0050] It should be noted that the size of the gap between the two sides of the limiting plate 1121 and the second clamping hole 212 is not limited. For example, the limiting plate 1121 and the second clamping hole 212 can be matched with a single-side gap of 1.5 mm in the second direction.

[0051] In some embodiments, reference Figure 2 , Figure 3 and Figure 4The guide bracket 1 is made of metal and is an integrally formed structure. Here, compared with the guide bracket 1 made of plastic, the guide bracket 1 made of metal has high strength, is not easy to deform, has high reliability, and is resistant to high temperatures. And because the guide bracket 1 made of metal has high strength, the guide portion 13, the side air curtain 3 mounting portion 12, and the first clamping portion 11 of the guide bracket 1 can be relatively thinned, or a hole 131 can be opened on the guide portion 13, thereby effectively reducing weight and saving costs. The metal integrally formed design, such as the guide bracket 1 can be integrally formed by stamping, makes the guide bracket 1 simple in structure, easy to install, and has high production efficiency and high reliability.
