Description

Technical Field

[0001] The present disclosure relates to the technical field of side air curtain structures, and in particular to an air curtain protection bracket, an air curtain installation structure and a vehicle. Background Art

[0002] When a car is involved in an accident, the airbag can well protect the safety of the driver and passengers. The injury areas of the occupants in a side collision are mainly concentrated in the head, neck, chest, abdomen, etc. Usually, a side air curtain is set in the cavity structure formed by the car body and the interior panel. When a side collision occurs, the side air curtain explodes and rushes out from the interior, separating the occupant's head or even the head and chest from the car interior to achieve the purpose of protecting the occupant's safety. However, with the gradual popularization of the current smart cockpit, more and more parts are installed on the ceiling of the interior parts around the side air curtain, from the traditional ceiling with only handle brackets to the current ceiling full of smart audio and video parts such as reading lights, speakers, microphones, etc., and these parts are generally purchased in a snap-on form to meet the assembly and disassembly requirements, which is easy to cause splashing during the deployment of the air curtain. Therefore, it is necessary to set a protective bracket around the side air curtain so that the protective bracket can protect the parts on the ceiling when the side air curtain expands, and avoid the expansion of the side air curtain impacting the parts on the ceiling and causing the parts to splash.

[0003] Since the existing protective bracket and side air curtain are two independent components, when the protective bracket and the side air curtain are assembled on the vehicle's body sheet metal, it is necessary to reserve a protective bracket mounting position for installing the protective bracket and a side air curtain mounting position for installing the side air curtain on the body sheet metal. For example, it is necessary to first install the protective bracket on the protective bracket mounting position of the body sheet metal, and then install the side air curtain on the side air curtain mounting position of the body sheet metal. This results in limited space for installation operations and affects the assembly efficiency of the vehicle. Utility Model Content

[0037] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0039] Reference Figures 1 to 7 As shown, the first aspect of the disclosed embodiment provides an air curtain protection bracket, including a bracket body 1, on which a connecting piece 2 is provided, and a side air curtain 3 is installed on the bracket body 1 through the connecting piece 2; a first through hole 111 is provided on the bracket body 1, and the first through hole 111 is used to correspond to the first mounting hole on the vehicle body sheet metal 4, so as to connect the bracket body 1 with the side air curtain 3 installed to the vehicle body sheet metal 4 at least by passing through the first through hole 111 and the first mounting hole.

[0040] Specifically, the side air curtain 3 is arranged inside the vehicle near the ceiling, and the side air curtain 3 extends inside the vehicle from the front of the vehicle toward the rear of the vehicle, that is, the extending direction of the side air curtain 3 is consistent with the length direction of the vehicle. The bracket body 1 can be selected as a plate structure, and the bracket body 1 extends along the extension direction of the side air curtain 3. The bracket body 1 can be selected to include two plates, one plate is arranged on a side surface of the other plate, and a first through hole 111 is provided on one plate. When the plate structure is installed on the body sheet metal 4, the other plate is located on the upper side of the side air curtain and between the side air curtain 3 and the roof of the vehicle, so as to form protection for the components on the ceiling when the side air curtain 3 expands; of course, the bracket body 1 can also be selected as a panel structure, and a skirt board is provided on one side edge of the panel, and the first through hole 111 is provided on the skirt board. The first through hole 111 on the skirt board is arranged opposite to the body sheet metal 4, and a first mounting hole corresponding to the first mounting hole can be provided on the body sheet metal 4, so that the first through hole 111 is arranged opposite to the first mounting hole on the body sheet metal 4, and the staff uses the first fastener 5 to pass through the first through hole 111 to connect with the body sheet metal 4.

[0041] The above-mentioned connector 2 can be selected as an adhesive tape or a plastic belt. The adhesive tape or plastic belt is bent to form an annular structure. The axial direction of the annular structure is consistent with the extension direction of the bracket body 1, so that the connector 2 with an annular structure can be sleeved on the outside of the bracket body 1, and the side air curtain 3 is inserted into the connector 2 with an annular structure, so that the side air curtain 3 is integrated and installed on the bracket body 1. When the connector 2 is an adhesive tape, the bracket body 1 and the connector 2 can be connected by bonding. When the connector 2 is a plastic belt, glue can be used to bond part of the connector 2 to the bracket body 1, or the plastic belt can maintain the stability of the relative position between the bracket body 1 and the bracket body 1 through friction. Of course, the connector 2 can also be selected as a buckle, and the side air curtain 3 is provided with a snap-on protrusion, and the snap-on protrusion is snapped with the buckle, so that the side air curtain 3 is integrated and installed on the bracket body 1.

[0042] Since the expansion of the side air curtain 3 requires the deformation and popping of the interior parts so that it can rush out of the interior parts, the impact force when the side air curtain 3 expands is relatively large. When the connecting member 2 is an annular structure, the structural strength of the connecting member 2 with an annular structure is adjusted according to the impact force when the side air curtain 3 expands, so that the connecting member 2 can bear the weight of the side air curtain 3. At the same time, the impact force when the side air curtain 3 expands can cause the connecting member 2 to break, so that the connecting member 2 will not hinder the expansion of the side air curtain 3; when the bracket body 1 is hung on the vehicle body sheet metal 4, the structural strength of the connecting member 2 can enable the side air curtain 3 to maintain an integrated installation state with the bracket body 1, so that the side air curtain 3 and the bracket body 1 are installed at the position where the side air curtain 3 needs to be installed on the vehicle body sheet metal 4. When the side air curtain 3 expands, the side air curtain 3 impacts the connecting member 2 and causes the connecting member 2 to break, so that the side air curtain 3 can expand and pop out smoothly.

[0043] The body sheet metal 4 may be provided with a through hole as the first mounting hole, or a screw hole as the first mounting hole, as long as the first fastener 5 can pass through the first through hole 111 and the first mounting hole, so that the first fastener 5 can connect the bracket body 1 to the body sheet metal 4. The first fastener 5 may include a bolt or a rivet, and the bolt is passed through the first through hole 111 and the first mounting hole to mount the bracket body 1 on the body sheet metal 4. As long as the first fastener 5 can pass through the first through hole 111 and the first mounting hole on the body sheet metal 4, so that the bracket body 1 is fixedly connected to the body sheet metal 4.

[0044] When the air curtain protection bracket provided by the embodiment of the present disclosure is used, the connecting piece 2 is sleeved on the outside of the bracket body 1, and the side air curtain 3 is inserted into the connecting piece 2, so that the side air curtain 3 is integrated and installed on the bracket body 1 through the connecting piece 2. The staff moves the bracket body 1 with the side air curtain 3 installed so that the first through hole 111 and the first mounting hole on the vehicle body sheet metal 4 are in a relatively set state. The staff passes the first fastener 5 through the first through hole 111 and the first mounting hole to fix the bracket body 1 with the vehicle body sheet metal 4 through the first fastener 5, thereby achieving the installation of the side air curtain 3 on the vehicle body sheet metal 4 while installing the bracket body 1.

[0045] The air curtain protection bracket provided by the embodiment of the present disclosure includes a bracket body 1, a connecting member 2 is arranged on the bracket body, and a side air curtain 3 is installed on the bracket body 1 through the connecting member 2, so that the side air curtain and the bracket body form a whole and are easy to install; a first through hole 111 is arranged on the bracket body 1, and the first through hole 111 is used to correspond to the first installation hole on the body sheet metal 4, so that the bracket body 1 installed with the side air curtain 3 is connected to the body sheet metal 4 at least by a first fastener 5 penetrated through the first through hole 111 and the first installation hole. When assembling on the body sheet metal 4, since the side air curtain 3 and the bracket body 1 are integrated into a whole, it is only necessary to connect the bracket body 1 with the body sheet metal 4 to complete the assembly operation of the side air curtain 3 and the bracket body 1 as a whole on the body sheet metal 4, so that the side air curtain 3 is installed on the body sheet metal 4 while the bracket body 1 is installed, which simplifies the steps of installing the air curtain protection bracket and the side air curtain 3 on the body sheet metal 4, improves the speed of assembling the air curtain protection bracket and the side air curtain 3 on the body sheet metal 4, and thus improves the assembly efficiency of the vehicle.

[0046] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, in some embodiments, the bracket body 1 is further provided with a pre-hook 13, which is used to hook with the body sheet metal 4, so as to pre-hook the bracket body 1 on the body sheet metal 4, and make the first through hole 111 and the first mounting hole arranged opposite to each other. With such arrangement, when the bracket body 1 with the side air curtain 3 installed is assembled on the vehicle body sheet metal 4, the pre-hook 13 is first hooked with the vehicle body sheet metal 4, and the bracket body 1 with the side air curtain 3 installed can be pre-installed on the vehicle body sheet metal 4, so that the first through hole 111 and the first mounting hole are arranged opposite to each other, which is convenient for the staff to pass the first fastener 5 through the first through hole 111 and the first mounting hole, that is, the staff only needs to hook the pre-hook 13 with the vehicle body sheet metal 4 to perform the operation of passing the first fastener 5 through the first through hole 111 and the first mounting hole, and the staff does not need to hold up the side air curtain 3 and the bracket body 1 to adjust the position of the bracket body 1 so that the first through hole 111 is opposite to the first mounting hole, so that the connection between the pre-hook 13 and the vehicle body sheet metal 4 plays a positioning role, which simplifies the operation of assembling the bracket body 1 and the side air curtain 3 and improves the efficiency of assembling the side air curtain 3 and the bracket body 1 on the vehicle body sheet metal 4.

[0047] Specifically, when the bracket body 1 is a plate structure, a first through hole 111 and a pre-hook 13 are provided on one plate. When the plate structure is installed on the body sheet metal 4, the other plate is located on the upper side of the side air curtain and between the side air curtain 3 and the roof of the vehicle, so as to provide protection for the components on the ceiling when the side air curtain 3 expands. Of course, the bracket body 1 can also be selected as a panel structure, and a skirt is provided on one side edge of the panel. The pre-hook 13 is arranged on one side edge of the panel where the skirt is provided, so that when the pre-hook 13 is hung on the body sheet metal 4, the skirt is arranged opposite to the body sheet metal 4, so that the first through hole 111 on the skirt is arranged opposite to the first mounting hole of the body sheet metal 4, which is convenient for the staff to use the first fastener 5 to pass through the first through hole 111 and connect with the body sheet metal 4.

[0048] A through hole can be optionally provided on the above-mentioned body sheet metal 4 as a pre-hanging hole 41, so that the pre-hook 13 can be inserted into the pre-hanging hole 41, so that the position of the bracket body 1 on the body sheet metal 4 remains stable. Of course, a hanging protrusion can also be provided on the body sheet metal 4, so that the pre-hook 13 can be hooked with the hanging protrusion, so that the position of the bracket body 1 and the body sheet metal 4 remains stable.

[0049] The relative positions of the first mounting hole and the pre-hanging hole 41 or the hanging protrusion on the above-mentioned body sheet metal 4 are consistent with the relative positions of the first through hole 111 and the pre-hook 13 on the bracket body 1, that is, when the pre-hook 13 is hooked with the pre-hanging hole 41 or the hanging protrusion, the bracket body 1 and the body sheet metal 4 are arranged relative to each other, so that the first through hole 111 and the axis center line of the first mounting hole of the body sheet metal 4 coincide with each other, so that when the staff installs the side air curtain 3 and the bracket body 1, they only need to hook the pre-hook 13 with the body sheet metal 4, so that the first through hole 111 and the first mounting hole on the body sheet metal 4 can be arranged relative to each other, so that the first fastener 5 can pass through the first through hole 111 and the first mounting hole, and the operation of connecting the bracket body 1 and the body sheet metal 4 through the first fastener 5 can be conveniently completed.

[0050] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the bracket body 1 includes a protective plate 12 and a mounting plate 11; the mounting plate 11 is arranged on one side of the protective plate 12, the pre-hook 13 and the first through hole 111 are arranged on the mounting plate 11, and the side air curtain 3 is located on the side of the protective plate 12 facing away from the mounting plate 11. In this arrangement, the mounting plate 11 is used as a mounting structure with the body sheet metal 4, and the pre-hook 13 is arranged on the mounting plate 11. After the pre-hook 13 is hooked with the body sheet metal 4, the mounting plate 11 can be arranged opposite to the body sheet metal 4, and the protective plate 12 can block the movement of the inflated side air curtain 3, so that the protective plate 12 can guide the expansion direction of the side air curtain 3, and play a protective effect on various parts in the vehicle.

[0051] Specifically, the protective plate 12 and the mounting plate 11 can be selected to be both plate structures. The protective plate 12 can be selected to be connected to one side edge of the mounting plate 11, and the protective plate 12 and the mounting plate 11 are perpendicular to each other or have a set angle so that the cross-section of the protective plate 12 and the mounting plate 11 is "L"-shaped. The protective plate 12 can be selected to be arranged in the horizontal direction and the mounting plate 11 can be arranged in the vertical direction. The protective plate 12 extends along the extension direction of the bracket body 1 to expand the protection area of ​​the protective plate 12, and the mounting plate 11 extends in the vertical direction in the direction away from the protective plate 12 to increase the area where the mounting plate 11 is relatively set to the body sheet metal 4, so as to facilitate the setting of the pre-hook 13 and the first through hole 111 on the mounting plate 11.

[0052] The above-mentioned mounting plate 11 is provided with a pre-hook 13 on one side surface away from the protective plate 12 in the horizontal direction, that is, the mounting plate 11 is provided with a pre-hook 13 on one side facing the body sheet metal 4 in the horizontal direction, so that when the pre-hook 13 is hooked with the body sheet metal 4, the mounting plate 11 is arranged opposite to the body sheet metal 4, and the first through hole 111 is arranged on the mounting plate 11, so that the first through hole 111 is arranged opposite to the first mounting hole on the body sheet metal 4 in the horizontal direction.

[0053] The above-mentioned side air curtain 3 is located on the side of the protective plate 12 facing away from the mounting plate 11, which can prevent the structure of the mounting plate 11 from interfering with the expansion of the side air curtain 3, so as to ensure that the side air curtain 3 can expand smoothly to pop out the interior decoration to protect the occupants; wherein the side air curtain 3 needs to pop out the interior decoration of the vehicle downward when it expands, so that the inflated side air curtain 3 can separate the head and chest of the occupant from the interior decoration of the vehicle to protect the occupants, the bracket body 1 is located on the upper side of the side air curtain 3, so as to prevent the mounting plate 11 and the protective plate 12 from interfering with the downward expansion of the side air curtain 3, and the protective plate 12 is located between the side air curtain 3 and the roof of the vehicle in the vertical direction. Smart audio and video components such as reading lights, speakers, and microphones are usually installed on the roof of the vehicle, so the protective plate 12 can protect the components when the side air curtain 3 expands to prevent the components from splashing.

[0054] Reference Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, there are multiple pre-hooks 13, and multiple pre-hooks 13 are arranged on the mounting plate 11 at intervals along the extension direction of the bracket body 1 to hook with the body sheet metal 4. In this way, the bracket body 1 can be hooked with the body sheet metal 4 through multiple pre-hooks 13, which improves the position stability of the bracket body 1 when it is hooked on the body sheet metal 4, and can prevent the bracket body 1 from rotating around the pre-hooks 13 when it is hooked on the body sheet metal 4, ensuring that when the bracket body 1 is connected to the body sheet metal 4 through the pre-hooks 13, the first through hole 111 and the first mounting hole on the body sheet metal 4 can maintain a relatively arranged state, so that it is convenient for the staff to pass the first fastener 5 through the first through hole 111 and the first mounting hole.

[0055] Specifically, the number of pre-hooks 13 can be selected to be two, and the two pre-hooks 13 are arranged on the mounting plate 11 at intervals along the extension direction of the bracket body 1, and the first through hole 111 can be selected to be arranged between the two pre-hooks 13. Of course, the first through hole 111 can also be selected to be arranged at other positions on the mounting plate 11, and two pre-hanging holes 41 are provided on the body sheet metal 4, and the distance between the two pre-hanging holes 41 is equal to the distance between the two pre-hanging holes 13, so that the two pre-hanging holes 13 are relatively arranged in a one-to-one correspondence with the two pre-hanging holes 41; of course, the pre-hooks 13 can also be selected to be other numbers, and the body sheet metal 4 is provided with pre-hanging holes 41 equal to the number of pre-hooks 13, so that multiple pre-hooks 13 are hooked with multiple pre-hanging holes 41 in a one-to-one correspondence.

[0056] Reference Figure 1 and Figure 2As shown, in some embodiments, the first through hole 111 is disposed between two adjacent pre-hooks 13. In this way, the first through hole 111 is close to the two pre-hooks 13, so that the two pre-hooks 13 are conveniently used as the position reference for setting the first through hole 111, and the position of the first through hole 111 is conveniently determined, so as to ensure that after the two pre-hooks 13 are hooked with the body sheet metal 4, the first through hole 111 and the first mounting hole on the body sheet metal 4 can be arranged relative to each other.

[0057] Specifically, the first through hole 111 is arranged between two adjacent pre-hooks 13 in the extension direction of the bracket body 1, and multiple pre-hooks 13 are connected to the body sheet metal 4. Even if the bracket body 1 is subjected to vibration, the position offset between two adjacent pre-hooks 13 is small, so that the first through hole 111 can maintain a stable relative position with the first mounting hole on the body sheet metal 4. In addition, the first through hole 111 is arranged between two adjacent pre-hooks 13, so that the first mounting hole on the body sheet metal 4 is also arranged between two adjacent pre-hanging holes 41, so that the first through hole 111 is close to the two pre-hanging holes 13, which is convenient for setting the first through hole 111 on the mounting plate 11 with the positions of the two pre-hanging holes 13 as a reference, and the corresponding first mounting hole on the body sheet metal 4 is close to the two pre-hanging holes 41, which is convenient for setting the first mounting hole on the body sheet metal 4 with the two pre-hanging holes 41 as a reference, ensuring that the relative arrangement of the first through hole 111 and the two pre-hanging holes 13 is consistent with the relative position of the first mounting hole and the two pre-hanging holes 41, so as to ensure that when the pre-hook 13 is hung on the body sheet metal 4, the first through hole 111 and the first mounting hole can be relatively arranged.

[0058] Reference Figure 1 and Figure 2 As shown, in some embodiments, the mounting plate 11 is further provided with a second through hole 112, and the second through hole 112 is used for the second fastener to pass through to connect with the second mounting hole on the body sheet metal 4. In this way, the bracket body 1 is connected to the body sheet metal 4 through the first fastener 5 and the second fastener, so that the bracket body 1 and the body sheet metal 4 have two connection points, thereby improving the position stability of the bracket body 1 when it is installed on the body sheet metal 4.

[0059] Specifically, a through hole can be selected on the mounting plate 11 as the second through hole 112, the second through hole 112 can be selected as an oblong hole, and the second through hole 112 extends along the extension direction of the bracket body 1, and a through hole or a screw hole can be selected on the body sheet metal 4 as the second mounting hole. When the bracket body 1 is hung on the body sheet metal 4, the second mounting hole and the second through hole 112 are arranged opposite to each other, so that the second fastener can easily pass through the second through hole 112 and connect with the second mounting hole, thereby increasing the connection points between the mounting plate 11 and the body sheet metal 4. The second fastener can be selected as a bolt or a rivet, as long as the second fastener can pass through the second through hole 112 and the second mounting hole to connect the mounting plate 11 to the body sheet metal 4.

[0060] The above-mentioned second through hole 112 extends in the extension direction of the bracket body 1, so that the second through hole 112 has a certain margin in the extension direction of the bracket body 1, so that even if the second through hole 112 has a processing error, it can be in a relatively set state with the second mounting hole on the body sheet metal 4, ensuring that the second fastener can be connected with the second mounting hole of the body sheet metal 4 after passing through the second through hole 112; and the size of the second through hole 112 in the horizontal direction is larger than the size in the vertical direction, so that after the second fastener passes through the second through hole 112, when the bracket body 1 is vibrated, the vertical movement of the bracket body 1 is reduced; the bracket body 1 and the body sheet metal 4 have two connection points, which can prevent the bracket body 1 from rotating around the first fastener 5 when it is vibrated, thereby improving the position stability of the bracket body 1 when it is installed on the body sheet metal 4.

[0061] Reference Figure 1 and Figure 4 As shown, in some embodiments, the connecting member 2 is formed into an annular structure, and the connecting member 2 is arranged around the outside of the support body 1 and the side air curtain 3, so as to integrally install the side air curtain 3 on the support body 1. In this way, the connecting member 2 of the annular structure can connect the side air curtain 3 with the support body 1 by sleeve arrangement, and the connecting member 2 does not need to be additionally provided with a connecting structure with the support body 1 and the side air curtain 3, thereby reducing the cost of the connecting member 2 and simplifying the connection operation of the connecting member 2 connecting the support body 1 and the side air curtain 3.

[0062] Specifically, the annular structure is sleeved on the outside of the bracket body 1 and the side air curtain 3, so that the inner wall of the annular structure abuts against the surface of the bracket body 1 and the side air curtain 3, so that the side air curtain 3 remains connected with the bracket body 1 through friction and the pressure of the annular structure on the surface of the bracket body 1 and the side air curtain 3, so as to realize the integrated installation of the side air curtain 3 on the bracket body 1.

[0063] Of course, the connecting member 2 can be selected as a tape, and the two ends of the tape are connected after being bent to form an annular structure, and the annular structure is sleeved on the outside of the bracket body 1 and the side air curtain 3. The side air curtain 3 is attached to the side of the protective plate 12 facing away from the mounting plate 11, and the side air curtain 3 is integrated and installed on the bracket body 1 by the structural strength and viscosity of the tape itself; of course, the connecting member 2 can also be selected as an annular structure made of plastic, as long as the connecting member 2 can be sleeved on the outside of the bracket body 1 and the side air curtain 3, and the connecting member 2 can break under the impact force when the side air curtain 3 is expanded, so that the connecting member 2 with the annular structure will not hinder the expansion of the side air curtain 3.

[0064] Reference Figure 1 and Figure 2 As shown, in some embodiments, the support body 1 is provided with a reinforcing rib 121, and the reinforcing rib 121 extends at least along the extension direction of the support body 1. In this way, the reinforcing rib 121 can improve the rigidity of the support body 1, reduce the deformation of the support body 1 when it is subjected to impact force, and prevent the support body 1 from deforming when the side air curtain 3 is inflated, thereby preventing the parts and components contacting the ceiling from being deformed to a large extent and being broken, thereby improving the protective effect of the support body 1 when the side air curtain 3 is inflated.

[0065] Specifically, a raised structure can be selected to be formed on the bracket body 1 as the reinforcing rib 121. Of course, a partial area on the protective plate 12 of the bracket body 1 can also be selected to be bent and raised upward to form the reinforcing rib 121. The reinforcing rib 121 can be selected to extend along the extension direction of the bracket body 1 on the protective plate 12, and a sub-reinforcing rib portion can be formed on the reinforcing rib 121, and the sub-reinforcing rib portion extends toward the mounting plate 11, and the sub-reinforcing rib portion extends to the mounting plate 11, so that the reinforcing rib 121 and the sub-reinforcing rib portion can increase the rigidity of the bracket body 1. The reinforcing rib 121 can improve the rigidity of the bracket body 1 and reduce the deformation of the bracket body 1 when it is impacted. Since the protective plate 12 is used to contact the inflated side air curtain 3, the reinforcing rib 121 can be selected to be set on the protective plate 12. The size of the reinforcing rib 121 is determined according to design requirements, as long as the deformation of the bracket body 1 is less than 1.5 mm when the side air curtain 3 expands and impacts the bracket body 1; if the deformation of the bracket body 1 is greater than 1.5 mm when the side air curtain 3 expands and impacts the bracket body 1, the bracket body 1 is likely to contact the ceiling and transfer the impact force of the side air curtain 3 to the components of the ceiling, and the large deformation of the bracket body 1 is also likely to cause itself to break, affecting the protective effect of the bracket body 1.

[0066] Reference Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, there are multiple connectors 2, and the multiple connectors 2 are arranged at intervals along the extension direction of the bracket body 1, and the side air curtain 3 is connected to the inside of the multiple connectors 2. In this way, the side air curtain 3 is connected to the bracket body 1 through the multiple connectors 2, which increases the position stability of the side air curtain 3 on the bracket body 1, reduces the shaking amplitude of the side air curtain 3 on the bracket body 1, and facilitates the installation of the side air curtain 3 and the bracket body 1 as a whole on the body sheet metal 4.

[0067] Specifically, the number of connecting parts 2 can be selected to be two, and the two connecting rings are respectively arranged at the two ends of the bracket body 1 along the extension direction of the bracket body 1, so that there are two connection points between the side air curtain 3 and the bracket body 1, so as to avoid the side air curtain 3 from shaking relative to the bracket body 1, and improve the stability of the side air curtain 3 when it is integrated and installed on the bracket body 1; of course, other numbers of connecting parts 2 can also be selected, as long as multiple connecting parts 2 are spaced apart on the outside of the bracket body 1 along the extension direction of the bracket body 1, and the side air curtain 3 can be connected to the bracket body 1 through multiple connecting parts 2.

[0068] Reference Figure 1 and Figure 4 As shown, in some embodiments, the connecting member includes an adhesive tape, which is formed into a ring structure to be bonded to the outer sides of the bracket body 1 and the side air curtain 3. In this way, the cost of the adhesive tape is low, and the adhesive tape itself has a bonding function, so that the adhesive tape can be sleeved on the outer sides of the bracket body 1 and the side air curtain 3 and can bond the bracket body 1 and the side air curtain 3 at the same time, thereby improving the stability of the side air curtain 3 when connected to the bracket body 1.

[0069] Specifically, the two ends of the bent tape are connected to form an annular structure, which is sleeved on the outside of the bracket body 1 and the side air curtain 3. The side air curtain 3 is attached to the side of the protective plate 12 facing away from the mounting plate 11, and the side air curtain 3 is integrated and mounted on the bracket body 1 by the structural strength and viscosity of the tape itself. The structural strength of the tape is relatively weak, and when the side air curtain 3 expands, the tape can break or the mutually bonded parts of the tape will separate, so that the tape will not hinder the expansion of the side air curtain 3.

[0070] Reference Figures 1 to 7 As shown, the second aspect of the disclosed embodiment provides an air curtain installation structure, including a vehicle body sheet metal 4, a side air curtain 3 and an air curtain protection bracket as described in any of the above items; a first installation hole for a first fastener 5 to pass through is provided on the vehicle body sheet metal 4, and a side air curtain 3 is installed on the bracket body 1 through a connecting member 2.

[0071] Specifically, the first mounting hole can be selected as a screw hole set on the body sheet metal 4. When the first fastener 5 is a bolt, the bolt passes through the first through hole 111 and is threadedly connected to the first mounting hole. Of course, the first mounting hole can also be selected as a through hole set on the body sheet metal 4. After using the bolt as the first fastener 5 and passing through the first through hole 111 and the first mounting hole, a nut is used to connect to the stud of the bolt to fix the bracket body 1 to the body sheet metal 4. Of course, the first fastener 5 can also be selected as a rivet, and the rivet passes through the first through hole 111 and the first mounting hole to rivet the bracket body 1 to the body sheet metal 4.

[0072] By setting up an air curtain installation structure including a vehicle body sheet metal 4, a side air curtain 3 and the above-mentioned air curtain protection bracket, a first installation hole is provided on the vehicle body sheet metal 4, and a first installation hole for a first fastener 5 to pass through is provided on the vehicle body sheet metal 4, and a side air curtain 3 is installed on the bracket body 1 through a connecting piece 2, and the bracket body 1 installed with the side air curtain 3 is connected to the first installation hole through the first fastener 5, so that the bracket body 1 is stably installed on the vehicle body sheet metal 4, and the side air curtain 3 is integrated and installed on the bracket body 1, so that the side air curtain 3 forms a whole with the bracket body 1 through the connecting piece 2, so that when the connection between the bracket body 1 and the vehicle body sheet metal 4 is completed, the side air curtain 3 can be installed on the vehicle body sheet metal 4 simultaneously, thereby reducing the steps of installing the air curtain protection bracket and the side air curtain 3 on the vehicle body sheet metal 4, and improving the installation efficiency of the side air curtain 3 and the air curtain protection bracket.

[0073] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments, the bracket body 1 is provided with a pre-hook 13, and the body sheet metal 4 is further provided with a pre-hook hole 41, and the pre-hook 13 is hooked with the pre-hook hole 41, so that the first mounting hole is arranged opposite to the first through hole 111. In this way, the pre-hook 13 is inserted into the pre-hook hole 41, so that the pre-hook 13 can bear the weight of the bracket body 1 and the side air curtain 3, and the pre-hook hole 41 has a positioning effect on the bracket body 1 during assembly, so that the bracket body 1 is conveniently and accurately installed at a position opposite to the first mounting hole.

[0074] Specifically, a through-hole seat pre-hanging hole 41 can be selected to be provided on the body sheet metal 4, and the size of the pre-hanging hole 41 matches the pre-hook 13, so that the pre-hook 13 can be inserted into the pre-hanging hole 41, wherein the pre-hook 13 can be selected to include a supporting portion and a hooking portion, the supporting portion is provided on the mounting plate 11, the hooking portion is provided at one end of the supporting portion away from the mounting plate 11, the hooking portion extends downward, and the supporting portion extends in a horizontal direction in a direction away from the mounting plate 11, so that the supporting portion and the hooking portion form a hook structure, and the horizontal distance between the hooking portion and the mounting plate 11 can be selected to be 28 mm, thereby ensuring that the supporting portion can be completely inserted into the pre-hanging hole 41, so that when the pre-hook 13 is hooked with the pre-hanging hole 41, the structural strength of the supporting portion and the hooking portion can support the weight of the bracket body 1 and the side air curtain 3, and at the same time, a larger space is provided between the hooking portion and the mounting plate 11, so that the edge of the pre-hanging hole 41 can enter the space between the hooking portion and the mounting plate 11 to complete the hooking operation of the pre-hanging hole 13 and the pre-hanging hole 41.

[0075] The relative positions of the first mounting hole and the pre-hanging hole 41 on the above-mentioned body sheet metal 4 are consistent with the relative positions of the first through hole 111 and the pre-hook 13 on the bracket body 1, that is, when the pre-hook 13 is hooked with the pre-hanging hole 41, the bracket body 1 and the body sheet metal 4 are arranged relative to each other, so that the first through hole 111 and the axial center line of the first mounting hole of the body sheet metal 4 coincide with each other, so that when the staff installs the side air curtain 3 and the bracket body 1, they only need to hook the pre-hook 13 with the body sheet metal 4, so that the first through hole 111 and the first mounting hole on the body sheet metal 4 can be arranged relative to each other, which facilitates the first fastener 5 to pass through the first through hole 111 and the first mounting hole, and conveniently completes the operation of connecting the bracket body 1 and the body sheet metal 4 through the first fastener 5.

[0076] Reference Figure 1 , Figure 4 and Figure 7 As shown, in some embodiments, the side air curtain 3 includes an air curtain body 31 and an ear piece 32; the ear piece 32 is arranged on the air curtain body 31, and a support hole 321 and an assembly hole 322 are arranged on the ear piece 32; the pre-hook 13 is passed through the support hole 321 and connected with the pre-hook hole 41; the first through hole 111, the assembly hole 322 and the first mounting hole are coaxially arranged, so that the first fastener 5 passes through the assembly hole 322, the first through hole 111 and the first mounting hole in sequence to connect. In this way, the pre-hook 13 can be passed through the support hole 321, so that the pre-hook 13 and the inner wall of the support hole 321 are abutted to share the weight of the side air curtain 3, and the stability of the side air curtain 3 after being integrated with the bracket body 1 is improved; the first fastener 5 can pass through the first through hole 111 and the assembly hole 322 in sequence and be connected with the first mounting hole, so that the ear piece 32 can also be connected with the body sheet metal 4 through the first fastener 5, and the stability of the side air curtain 3 on the body sheet metal 4 is improved.

[0077] Specifically, the air curtain body 31 can be selected as an inflatable airbag, the air curtain body 31 extends from the front of the vehicle toward the rear of the vehicle, the ear piece 32 is a sheet structure connected to the air curtain body 31, the support hole 321 and the assembly hole 322 can be selected as through holes that penetrate the ear piece 32, and the pre-hook 13 on the mounting plate 11 passes through the support hole 321 and is exposed on the side of the ear piece 32 that is away from the mounting plate 11; the ear piece 32 is fitted with the mounting plate 11 of the bracket body 1, and at this time, the assembly hole 322 of the ear piece 32 is arranged opposite to the first through hole 111, so that the first fastener 5 can be simultaneously penetrated in the first through hole 111 and the assembly hole 322; the pre-hook 13 is penetrated in the support hole 321, so that the pre-hook 13 can form a support for the ear piece 32 in the vertical direction, so that the pre-hook 13 shares the weight of the side air curtain 3 when it abuts against the inner wall of the support hole 321, thereby improving the stability of the integrated installation of the side air curtain 3 and the bracket body 1.

[0078] The sizes of the above-mentioned support hole 321 and the pre-hook 13 match each other, and the sizes of the assembly hole 322 and the first through hole 111 match each other; when the bracket body 1 and the side air curtain 3 are installed on the body sheet metal 4, the ear piece 32 is located between the mounting plate 11 of the bracket body 1 and the body sheet metal 4, and the two side surfaces of the ear piece 32 in the horizontal direction are respectively attached to the mounting plate 11 and the body sheet metal 4, and the assembly hole 322 is respectively arranged opposite to the first through hole 111 and the first mounting hole in the horizontal direction, so that the first fastener 5 can pass through the first through hole 111 and the assembly hole 322 in sequence and be connected to the first mounting hole, so that the ear piece 32 can also be connected to the body sheet metal 4 through the first fastener 5, thereby improving the stability of the side air curtain 3 on the body sheet metal 4.

[0079] A third aspect of an embodiment of the present disclosure provides a vehicle, comprising the air curtain mounting structure as described above.

[0080] By using the air curtain installation structure as described above in the vehicle, the side air curtain 3 and the air curtain protection bracket are integrated into a whole for installation, thereby simplifying the assembly steps of the side air curtain 3 and the air curtain protection bracket; and during installation, the staff can hang the pre-hook 13 in the pre-hanging hole 41 on the body sheet metal 4, so that the first through hole 111 and the first mounting hole are arranged opposite to each other, so that the staff can use the first fastener 5 to pass through the first through hole 111 and the first mounting hole, so as to quickly and conveniently install the side air curtain 3 and the air curtain protection bracket on the body sheet metal 4 together.

[0081] When the air curtain protection bracket and air curtain installation structure provided by the embodiment of the present disclosure are used specifically, the connecting member 2 is sleeved on the outer side of the bracket body 1, and the side air curtain 3 is inserted into the connecting member 2. The side air curtain 3 is located at the lower side of the protective plate 12, and the mounting plate 11 is located at the upper side of the protective plate 12. The pre-hook 13 on the mounting plate 11 passes through the support hole 321 on the ear piece 32, and the ear piece 32 is fitted with the mounting plate 11. The support hole 321 on the ear piece 32 is arranged opposite to the first through hole 111. The pre-hook 13 is passed through the pre-hook hole 41 on the body sheet metal 4, so that the mounting plate 11 and the ear piece 32 are arranged opposite to the body sheet metal 4, and the first through hole 111, the support hole 321 and the first mounting hole coincide with the axial center lines in the horizontal direction. The staff uses the first fastener 5 to pass through the first through hole 111, the support hole 321 and the first mounting hole in sequence to fix the bracket body 1 and the ear piece 32 to the body sheet metal 4, thereby completing the operation of installing the side air curtain 3 and the bracket body 1 together on the body sheet metal 4. When the side air curtain 3 expands, the protective plate 12 of the bracket body 1 is located on the upper side of the side air curtain 3, so that the protective plate 12 prevents the side air curtain 3 from impacting the roof of the vehicle, thereby protecting the components in the roof and preventing the components in the vehicle roof from splashing.
