DETAILED DESCRIPTION
[0039] In the present application, the terms "top", "bottom", "front", "back", orientation or positional relationship are based on the orientation or positional relationship shown in the drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application. Figure 1
[0040] An embodiment of the present application provides an airbag supporting structure 30 for supporting an airbag 20 after inflation and deployment.
[0041] It should be noted that the airbag supporting structure 30 of the embodiment of the present application can be used to support the airbag 20 after inflation and deployment at various positions of the vehicle. For the purpose of description, please refer to Figure 1 The embodiment of the present application takes the airbag supporting structure 30 for supporting the airbag 20 arranged at the front side of the co-driver seat 40 as an example for description.
[0042] It can be understood that in the normal driving state of the vehicle, the airbag 20 is accommodated at the front side of the co-driver seat 40 and is not inflated and deployed. In the event of a collision accident or other situations, the airbag 20 will be inflated and deployed rapidly to protect the passenger in the co-driver seat 40.
[0043] Please refer to Figure 2 and Figure 3 The airbag supporting structure 30 comprises a plate body assembly 31 and a driving assembly 32. The plate body assembly 31 comprises a main body 311 and a supporting piece 312. The main body 311 defines a containing space with a mounting port 311a. The supporting piece 312 has an initial state at the mounting port 311a and a supporting state extending away from the mounting port 311a to support the airbag 20 after inflation and deployment.
[0044] Specifically, the specific structure of the plate body assembly 31 is different according to the different positions of the airbag supporting structure 30. For example, the plate body assembly 31 is an instrument panel assembly. The airbag supporting structure 30 is used to support the airbag 20 arranged at the front side of the co-driver seat 40.
[0045] The position of the mounting port 311a on the main body 311 can be determined according to the position of the airbag 20 after inflation and deployment. For example, the mounting port 311a is located at the bottom side of the airbag 20 after inflation and deployment, so that the supporting piece 312 extending from the mounting port 311a pushes the airbag 20 from the bottom side, thereby supporting the airbag 20 after inflation and deployment.
[0046] The initial state of the supporting piece 312 refers to the state of the supporting piece 312 at the mounting port 311a in the normal driving state of the vehicle.
[0047] In the initial state, the specific position of the supporting piece 312 is not limited. For example, the supporting piece 312 can be located at the front side or the rear side of the mounting port 311a in the driving direction of the vehicle to shield the mounting port 311a. Of course, it can also be that at least part of the area extends into the mounting port 311a.
[0048] The specific structure of the support 312 is not limited, for example, it can be a support plate with an outer dimension matching that of the mounting hole 311a, which is clamped at the mounting hole 311a and can be separated from the mounting hole 311a under the driving of the driving assembly 32.
[0049] The support state of the support 312 refers to the state in which the support 312 extends to support the airbag 20 when the airbag 20 is inflated and deployed under certain conditions, such as a collision accident or other conditions.
[0050] In this case, the support 312 extends in a direction away from the mounting hole 311a, which is actually moving towards the side of the inflated and deployed airbag 20.
[0051] It should be noted that the extension of the support 312 and the inflation and deployment of the airbag 20 can be performed at different times according to actual conditions. It can also be performed at the same time as the inflation and deployment of the airbag 20 to ensure that the inflated and deployed airbag 20 is supported in the first time.
[0052] The driving assembly 32 drives the movement of the support 312 to switch the support 312 from the initial state to the support state.
[0053] The extension of the support 312 is achieved by moving under the driving action of the driving assembly 32. For example, the driving assembly 32 drives the support 312 to translate.
[0054] The specific structure of the driving assembly 32 is not limited, as long as it can drive the movement of the support 312.
[0055] For example, please refer to Figure 2 , Figure 8 and Figure 9 , the driving assembly includes an electromagnet 321 and a magnetic attraction piece 322 arranged on the support 312. When the electromagnet 321 is in an energized state, the magnetic pole of the end of the electromagnet 321 close to the magnetic attraction piece 322 generates the same magnetic force as the magnetic pole of the end of the magnetic attraction piece 322 close to the electromagnet 321, so that the electromagnet 321 and the permanent magnet generate a repulsive force to drive the movement of the support 312.
[0056] Specifically, the driving action of the driving assembly 32 is achieved by forming a repulsive force between the electromagnet 321 and the magnetic attraction piece 322 after the electromagnet 321 is energized.
[0057] In this case, the magnetic attraction piece 322 is a component capable of generating a magnetic field, which has a magnetic pole, such as a permanent magnet. Its shape is not limited, and it can be a magnetic strip arranged on the support 312.
[0058] The electromagnet 321 can generate an electromagnetic field after being powered on, and also has magnetic poles. By setting the same poles of the electromagnet 321 after being powered on and the magnetic attraction piece 322 close to each other on one side, the electromagnet 321 can repel each other due to the repulsion of the same magnetic poles after being powered on, so that the electromagnet 321 drives the magnetic attraction piece 322 to move by pushing the magnetic attraction piece 322 to drive the support 312 to move.
[0059] In addition, the driving assembly 32 can also adopt other driving structures, such as driving the air bag 20 to inflate and push to drive, or using an oil cylinder, a motor or other driving structures that can drive the support 312 to move. Of course, it can be understood that the driving assembly 32 needs to have a fast response speed and can drive the support 312 to move quickly.
[0060] In addition, the electromagnet 321 is not arranged on the support 312, and the specific arrangement position can be determined according to the actual situation. For example, the driving assembly 32 includes a mounting plate arranged on the main body 311, and a plurality of electromagnets 321 are arranged on the mounting plate. The magnetic attraction piece 322 on the support 312 corresponds to and is arranged opposite to the electromagnet 321.
[0061] Another embodiment of the application provides a vehicle, please refer to Figure 1 , including a vehicle body 10, an air bag 20 arranged on the vehicle body 10, and an air bag support structure 30 according to any embodiment of the application, the air bag support structure 30 is arranged on the vehicle body 10 to support the air bag 20 after inflation and expansion.
[0062] It should be noted that the air bag support structure 30 can be used to support the air bag 20 after inflation and expansion at different positions of the vehicle body 10.
[0063] For example, please refer to Figure 1 , the vehicle includes a co-driver seat 40 arranged in the vehicle body 10, and the air bag support structure 30 is arranged on the front side of the co-driver seat 40 along the driving direction of the vehicle, and the support 312 faces the co-driver seat 40.
[0064] Specifically, the air bag support structure 30 is used to support the air bag 20 on the front side of the co-driver seat 40, which can prevent the air bag 20 from falling down along the instrument panel after inflation and expansion, and avoid falling into the avoidance space on the bottom side of the instrument panel.
[0065] It should be noted that when the air bag support structure 30 is arranged on the front side of the co-driver seat 40, the plate body assembly 31 can be an instrument panel assembly.
[0066] For example, the instrument panel assembly includes a main body 311 having a receiving space and a support 312, the main body 311 includes an instrument panel upper plate and an instrument panel front plate located on the side of the instrument panel upper plate close to the co-driver seat 40, and a mounting port 311a is located on the instrument panel front plate. The support 312 and the driving assembly 32 are located in the receiving space, and the support 312 can support the airbag 20 from the bottom side of the airbag 20 after extending out of the mounting port 311a, thereby ensuring the stability of the airbag 20 to reduce the injury of the head and neck of the passenger on the co-driver seat 40.
[0067] Therefore, due to the airbag support structure 30, the distance between the instrument panel assembly and the co-driver seat 40 can be increased as much as possible without worrying that the airbag 20 cannot provide better protection after inflation and deployment due to falling, thereby ensuring a larger co-driver space and meeting the diversified needs of passengers.
[0068] The airbag support structure 30 of the embodiment includes a plate body assembly 31 and a driving assembly 32, the plate body assembly 31 includes a main body 311 and a support 312, the main body 311 defines a receiving space having a mounting port 311a, and the support 312 has an initial state located at the mounting port 311a and a support state extending away from the mounting port 311a to support the airbag 20 after inflation and deployment, and the driving assembly 32 drives the support 312 to move to switch the support 312 from the initial state to the support state. Therefore, the support 312 can be moved to the airbag 20 after inflation and deployment under the driving action of the driving assembly 32 to form effective support for the airbag 20. For example, the airbag support structure 30 is used to support the airbag 20 on the front side of the co-driver seat 40, which can prevent the airbag 20 on the front side of the co-driver seat 40 from deviating from the preset position after inflation and deployment and falling into the avoidance space on the bottom side of the instrument panel, so that the airbag 20 can provide better protection for the passenger on the co-driver seat 40. Therefore, the safety hazard of the airbag 20 can be reduced, and the safety performance of the airbag 20 is greatly improved.
[0069] In an embodiment, referring to Figures 4 to 6 , the airbag support structure 30 includes a limiting assembly 33 which can be used to limit the movement of the support 312 so that the support 312 can move to the preset position.
[0070] The limiting assembly 33 includes a first limiting structure 331 and a second limiting structure 336, one of the first limiting structure 331 and the second limiting structure 336 is arranged on the support 312, and the other is arranged on the main body 311, when the support 312 is in the support state, the first limiting structure 331 cooperates with the second limiting structure 336 to prevent the support 312 from moving.
[0071] Specifically, according to actual conditions, the first limiting structure 331 can be arranged on the support 312, and the second limiting structure 336 can be arranged on the main body 311. Alternatively, the second limiting structure 336 can be arranged on the support 312, and the first limiting structure 331 can be arranged on the main body 311.
[0072] The limiting structure of the first limiting structure 331 and the second limiting structure 336 located on the support 312 can move with the movement of the support 312, and the limiting structure located on the main body 311 will not move, so that the first limiting structure 331 and the second limiting structure 336 can be caused to form relative movement.
[0073] Through the cooperation of the first limiting structure 331 and the second limiting structure 336, the support 312 can be prevented from moving further away from the mounting port 311a when the support 312 supports the airbag 20 after inflation and expansion, so that the support 312 can be prevented from exceeding the preset position or being directly pushed out and falling off from the main body 311 under the driving action of the driving assembly 32.
[0074] It can be understood that the first limiting structure 331 and the second limiting structure 336 will not hinder the movement of the support 312 during the movement of the support 312 from the initial state to the supporting state.
[0075] In addition, the specific structure of the first limiting structure 331 and the second limiting structure 336 is not limited.
[0076] For example, referring to Figure 10 and Figure 11 , the first limiting structure includes an elastic member 332 and a limiting block 333, the limiting block 333 is connected with the elastic member 332, and the second limiting structure 336 has a limiting hole 336a. When the support 312 is in the supporting state, the limiting block 333 extends into the limiting hole 336a under the elastic force of the elastic member 332.
[0077] Specifically, the elastic member 332 is a structure with elastic force, such as a spring. The limiting block 333 can move under the elastic force of the elastic member 332 by being connected with the elastic member 332. Moreover, during the movement of the support 312, relative displacement will be formed between the first limiting structure 331 and the second limiting structure 336, so that relative displacement will be formed between the limiting block 333 and the limiting hole 336a. When the support 312 is in the supporting state, the extending end of the limiting block 333 will be aligned with the limiting hole 336a, so that the limiting block 333 extends into the limiting hole 336a under the elastic force of the elastic member 332, thereby preventing the movement of the support 312.
[0078] It should be noted that, since the first limiting structure 331 and the second limiting structure 336 are limited by the limiting block 333 extending into the limiting hole 336a, it can not only prevent the support 312 from moving further away from the mounting port 311a when the support 312 supports the airbag 20 after inflation and expansion, but also avoid the situation that the support 312 moves towards the mounting port 311a under the action of the reaction force of the airbag 20 due to insufficient support force of the support 312 under special circumstances (e.g., the passenger hits the airbag 20).
[0079] For example, referring to Figure 10 and Figure 11 , the first limiting structure further comprises a limiting shell 334, the limiting shell 334 has a mounting cavity 334a, at least one side of the opposite sides of the mounting cavity 334a has an opening 334b, the limiting block 333 corresponds to the opening 334b one by one, the elastic member 332 is arranged in the mounting cavity 334a, the support 312 is in the initial state, the limiting block 333 is at least partially received in the mounting cavity 334a, the support 312 is in the supporting state, and the limiting block 333 extends into the corresponding limiting hole 336a through the corresponding opening 334b.
[0080] Specifically, the mounting cavity 334a can have only one side with an opening 334b, so that only one limiting block 333 corresponding to the opening 334b is arranged. Of course, the opposite sides can also have openings 334b, so that two limiting blocks 333 corresponding to the openings 334b can be arranged.
[0081] It can be understood that the opening 334b needs to be arranged on one side of the elastic member 332 along the extension direction, so that the elastic member 332 can push the limiting block 333 to extend into the corresponding limiting hole 336a through the corresponding opening 334b by extension and contraction.
[0082] Of course, the limiting hole 336a and the opening 334b and the limiting block 333 are also one by one. When the support 312 is in the initial state, the limiting hole 336a and the opening 334b are not connected, the elastic member 332 is in the compressed state, and according to the actual situation, the limiting block 333 can be only partially received in the mounting cavity 334a, or all regions can be located in the mounting cavity 334a. When the support 312 is in the supporting state, the limiting hole 336a and the corresponding opening 334b are connected, the elastic member 332 pushes the limiting block 333 to extend into the limiting hole 336a by extension and contraction, thereby achieving the limiting effect.
[0083] In addition, referring to Figure 11 , according to the actual situation, the position of the limiting block 333 relative to the mounting cavity 334a is not limited.
[0084] For example, the limiting block 333 has opposite first and second ends 3331 and 3332, and when the support 312 is in the supporting state, the first end 3331 is located in the mounting cavity 334a, and the second end 3332 extends into the limiting hole 336a.
[0085] Specifically, part of the limiting block 333 is located in the mounting cavity 334a, and part of the limiting block 333 extends into the limiting hole 336a. In this way, the connection between the limiting shell 334 and the limiting block 333 is more stable, and the movement of the first limiting structure 331 as a whole can be better limited, thereby preventing the support 312 from moving.
[0086] In addition, the specific structure of the limiting block 333 is not limited.
[0087] For example, referring to Figure 10 and Figure 11 , the outer size of the first end 3331 is greater than the outer size of the opening 334b. In this way, the limiting block 333 can be prevented from being completely extended from the opening 334b during the process of extending into the limiting hole 336a, thereby reducing the limiting effect of the first limiting structure 331.
[0088] For another example, the outer size of the second end 3332 is greater than the outer size of the opening 334b. In this way, in the case that the entire region of the limiting block 333 is accommodated in the mounting cavity 334a, the extending end of the limiting block 333 can be prevented from being misaligned with the opening 334b, so that after the opening 334b and the limiting hole 336a are communicated, the limiting block 333 can be more smoothly extended into the limiting hole 336a.
[0089] For another example, the limiting block 333 has a connecting channel 333a extending from the first end 3331 to the second end 3332, and the elastic member 332 extends into the connecting channel 333a and abuts against the limiting block 333. In this way, the connection between the elastic member 332 and the limiting block 333 can be more stable, and the force transmission between the elastic member 332 and the limiting block 333 can be more smooth.
[0090] In an embodiment, referring to Figure 5 and Figure 6 , the first limiting structure 331 includes a first guide portion, and the second limiting structure 336 includes a second guide portion 337, and the first guide portion cooperates with the second guide portion 337 to guide the support 312 during the process of switching the support 312 from the initial state to the supporting state.
[0091] Specifically, the first limiting structure 331 and the second limiting structure 336 can not only limit the support 312 when the support 312 is in the supporting state, but also guide the movement of the support 312 when the support 312 is switched from the initial state to the supporting state, so that the support 312 can move to the set position more smoothly.
[0092] It should be noted that the matching mode of the first guide part and the second guide part 337 is determined according to the specific structure, such as sliding fit or rolling fit.
[0093] For example, the second guide part 337 is a sliding groove, and the second limiting structure 336 can be connected to the main body 311 by being folded to form a folded edge. The first guide part can be a structure that can slide along the sliding groove, such as a plate body that can slide along the sliding groove, or a pulley or a slide rail that has a sliding fit with the sliding groove.
[0094] In an embodiment, please refer to Figure 5 The first limiting structure 331 is arranged on the support 312, and the first guide part is a limiting plate 335 with a limiting folded edge 3351, which is located on the side of the second limiting structure 336 away from the mounting port 311a. When the support 312 is in the supporting state, the limiting folded edge 3351 abuts against the second limiting structure 336.
[0095] On the one hand, the limiting plate 335 can cooperate with the second guide part 337 to guide the movement of the support 312. On the other hand, the support 312 can be limited when it supports the air bag 20 after being inflated and expanded.
[0096] Specifically, the first limiting structure 331 is arranged on the support 312, and the second limiting structure 336 is arranged on the main body 311. Due to the cooperation of the first guide part and the second guide part 337, the first limiting structure 331 can move relative to the second limiting structure 336 when the support 312 is switched from the initial state to the supporting state. When the support 312 is in the supporting state, the second limiting structure 336 can abut against the limiting folded edge 3351 to prevent the movement of the support 312 by preventing the movement of the first limiting structure 331.
[0097] In some embodiments, the first limiting structure 331 and the second limiting structure 336 can only abut against each other through the limiting folded edge 3351 and the second limiting structure 336 to prevent the movement of the support 312, or only through the limiting block 333 extending into the limiting hole 336a to prevent the movement of the support 312. Of course, both of the above limiting methods can be used to prevent the movement of the support 312.
[0098] In an embodiment, please refer toFigures 5 to 8 The support member 312 has a connecting flange 3122 folded towards a side close to the limiting plate 335, and the limiting plate 335 is connected with the connecting flange 3122.
[0099] Specifically, the support member 312 can strengthen the connection stability between the support member 312 and the limiting plate 335 by forming the connecting flange 3122 to connect with the limiting plate 335.
[0100] According to actual conditions, the limiting plate 335 and the connecting flange 3122 can be connected by bolts, rivets, adhesives or other connection methods.
[0101] In a specific embodiment, referring to Figures 5 to 7 The limiting plate 335 and the connecting flange 3122 have first and second mounting holes respectively, and the limiting shell 334 is arranged in the first and second mounting holes. The second limiting structure 336 has a sliding slot and a limiting hole 336a, and the limiting plate 335 and the connecting flange 3122 slide along the sliding slot during the movement of the support member 312.
[0102] In an embodiment, referring to Figures 5 to 8 At least part of the outer edge of the support member 312 is folded to form the flange 3122, and the flange 3122 is in interference fit with the mounting port 311a when the support member 312 is in the supporting state.
[0103] Specifically, all of the outer edge of the support member 312 can be folded to form the flange 3122, or only part of the outer edge of the support member 312 can be folded to form the flange 3122.
[0104] When the support member 312 is at the mounting port 311a, at least part of the flange 3122 extends into the mounting port 311a to interfere with the mounting port 311a. In this way, on the one hand, the friction between the support member 312 and the side wall of the mounting port 311a can be increased to prevent the support member 312 from shaking during normal driving of the vehicle, thereby improving the stability of the support member 312 at the mounting port 311a, and on the other hand, the outer surface of the plate body assembly 31 can be made flat.
[0105] In a specific embodiment, the installation steps of the airbag support structure 30 during assembly are as follows:
[0106] Step S1: The upper and lower ends of the elastic member 332 are connected with one limiting block 333 through the connecting channel 333a respectively, and the elastic member 332 and the two limiting blocks 333 connected therewith are inserted into the limiting shell 334 and tightened.
[0107] Step S2: The second limiting structure 336 with the sliding slot is placed inside the main body 311, and the second limiting structure 336 is fixed on the main body 311 by bolts.
[0108] Step S3: bolt the electromagnet 321 to the mounting plate, and place the mounting plate inside the main body 311 and in front of the mounting port 311a, and bolt the mounting plate to the main body 311.
[0109] Step S4: paste the magnetic strip on the front side of the support 312 at the mounting port 311a, push the connecting flange 3122 of the support 312 into the sliding groove from the rear side of the second limiting structure 336, push the limiting plate 335 into the sliding groove from the front side of the second limiting structure 336, bolt the limiting plate 335 to the support 312, adjust the position of the support 312 and the limiting plate 335 along the direction of the sliding groove, press the limiting block 333 into the mounting cavity 334a of the limiting shell 334, and snap into the sliding groove to ensure that the elastic member 332 is in a compressed state.
[0110] Step S5: press the support 312 and the mounting port 311a to interfere fit, and snap them together.
