Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and particularly to a vehicle side airbag installation mechanism, a control method, an electronic device, and a storage medium. Background Art

[0002] The side airbags on a vehicle are used to be detonated when the vehicle has a collision to protect the occupants. As Figures 1 to 2 shown, the side airbag 1' is installed on the side wall sheet metal above the left and right sides of the vehicle interior ceiling 4', is installed in the space surrounded by the vehicle body 2', the trim panel 3', and the ceiling 4', and is guided by the side airbag guiding structure. Among them, as Figure 1 shown, the side airbag guiding structure can be a separate independent side airbag guiding structure 5'. In addition, as Figure 2 shown, the side airbag guiding structure can also extend from the trim panel 3' to form a trim panel guiding structure 31'.

[0003] However, regardless of which side airbag guiding structure it is, the existing side airbag guiding structures are all rigidly fixed guiding structures. As Figure 1 shown, the independent side airbag guiding structure 5' is fixed to the vehicle body 2' by bolts 6'. As Figure 2 shown, the trim panel guiding structure 31' is an extended part of the trim panel 3', and the trim panel 3' is fixed to the vehicle body 2' by bolts 7'. Therefore, the side airbag guiding structure is fixed to the vehicle body 2' or the trim panel 3', and cannot move relative to the vehicle body sheet metal 1' or the trim panel 3'.

[0004] Due to the side airbag guiding performance requirements, the side airbag guiding structure needs to be close to the side airbag 1' so that the side airbag 1' can be guided by the side airbag guiding structure when detonated, so as to break away from the trim panel 3' and the ceiling 4' and extend into the occupant compartment to play a role in protecting the vehicle occupants. Therefore, the side airbag guiding structure must be close to the side airbag 1' and can only occupy the space above the overlapping part of the trim panel 3' and the ceiling 4', resulting in a large space required for the side airbag guiding structure. Therefore, the side airbag guiding structure of the prior art is contrary to the market demand for a large interior space of the vehicle. Either it has a great impact on the spatial layout and shape of the vehicle body, ceiling, and trim panel, or it cannot meet the side airbag performance design requirements. Summary of the Invention

[0014] When a collision signal is detected, control the driving device to drive the side air curtain guiding structure to move towards the side air curtain to the air curtain guiding position, and detonate the side air curtain.

[0016] The step of controlling the driving device to keep the side air curtain guiding structure at the starting position specifically includes: controlling the variable polarity magnetic structure to adsorb the fixed polarity magnetic structure to keep the side air curtain guiding structure at the starting position;

[0017] The step of controlling the driving device to drive the side air curtain guiding structure to move towards the side air curtain to the air curtain guiding position specifically includes: controlling the variable polarity magnetic structure to repel the fixed polarity magnetic structure to drive the side air curtain guiding structure to move towards the side air curtain to the air curtain guiding position.

[0026] By providing a side airbag guiding structure that can be driven by a driving device, the side airbag guiding structure has a starting position and an airbag guiding position.

Detailed implementation manners

[0041] The following further illustrates the detailed implementation manners of the present invention with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0042] As Figure 3The following is a schematic structural diagram of a vehicle side airbag installation mechanism according to an embodiment of the present invention, including: a vehicle body sheet metal 1, a trim panel 2, and a roof 3. The trim panel 2 includes a trim panel main body 21 fixedly connected to the vehicle body sheet metal 1. The trim panel main body 21 is provided with a trim panel extension part 22 extending towards the roof 3. The end of the trim panel extension part 22 is overlapped with the roof 3. The vehicle body sheet metal 1, the trim panel 2, and the roof 3 are connected to enclose a side airbag accommodation space for accommodating the side airbag 4. It further includes a side airbag guiding structure 5 and a driving device 6. The side airbag guiding structure 5 is arranged in the side airbag accommodation space and is located between the side airbag 4 and the trim panel main body 21. The driving device 6 is connected to the side airbag guiding structure 5, and the driving device 6 is electrically connected to a controller. The controller 7 controls the driving device 6 to drive the side airbag guiding structure 5 to remain at a starting position or move towards the side airbag 4 to an airbag guiding position in the side airbag accommodation space. When at the starting position, the distance between the side airbag guiding structure 5 and the side airbag 4 is a first distance, and when at the airbag guiding position, the distance between the side airbag guiding structure 5 and the side airbag 4 is a second distance, and the first distance is greater than the second distance.

[0043] Specifically, as Figure 3 shown, the vehicle body sheet metal 1 and the roof 3 are arranged opposite to each other. The trim panel 2 can be arranged below. Among them, the trim panel main body 21 is fixedly connected to the vehicle body sheet metal 1. The trim panel extension part 22 extends towards the roof 3 and is overlapped with the roof 3. The overlapping position of the trim panel extension part 22 and the roof 3 is an overlapping point.

[0044] In some embodiments, the end of the roof 3 is overlapped with the end of the trim panel extension part 22, and the distance between the end of the roof 3 and the vehicle body sheet metal 1 is less than the distance between the end of the trim panel extension part 22 and the vehicle body sheet metal 1.

[0045] The vehicle body sheet metal 1, the trim panel 2, and the roof 3 enclose a side airbag accommodation space. The side airbag 4 is accommodated in the side airbag accommodation space. The specific settings of the vehicle body, the trim panel, the roof, and the side airbag can be realized by using the existing side airbag space layout method. Among them, it is preferably that the vehicle body sheet metal in the vehicle body sheet metal 1, the trim panel 2, and the roof 3 enclose the side airbag accommodation space.

[0046] A side airbag guiding structure 5 is arranged in the side airbag accommodation space. The side airbag guiding structure 5 is located between the side airbag 4 and the trim panel main body 21. The driving device 6 is connected to the side airbag guiding structure 5 and drives the side airbag guiding structure 5.

[0047] In some embodiments, the driving device 6 is fixed to the trim panel main body 21.

[0048] In some embodiments, the trim panel 2 is disposed below the ceiling 3. Inside the side curtain airbag accommodation space, from top to bottom, there are a side curtain airbag 4, a side curtain airbag guiding structure 5, and a driving device 6 in sequence.

[0049] The driving device 6 is electrically connected to the controller 7. The controller 7 controls the driving device 6 such that the driving device 6 drives the side curtain airbag guiding structure 5 to remain at the starting position within the side curtain airbag accommodation space; or drives the side curtain airbag guiding structure 5 to move towards the side curtain airbag 4 within the side curtain airbag accommodation space to the airbag guiding position.

[0050] Wherein, at the starting position, the distance between the side curtain airbag guiding structure 5 and the side curtain airbag 4 is a first distance, and at the airbag guiding position, the distance between the side curtain airbag guiding structure 5 and the side curtain airbag 4 is a second distance, and the first distance is greater than the second distance. Therefore, at the starting position, the side curtain airbag guiding structure 5 is far from the side curtain airbag 4 and closer to the trim panel main body 21, while at the airbag guiding position, the side curtain airbag guiding structure 5 is close to the side curtain airbag 4 and far from the trim panel main body 21, providing a guiding function for the side curtain airbag 4. The side curtain airbag guiding structure 5 can adopt various existing shapes of side curtain airbag guiding structures.

[0051] In some embodiments, the side curtain airbag guiding structure 5 includes a first guiding plate 51, a second guiding plate 52, and a third guiding plate 53 connected in sequence. The first guiding plate 51 and the second guiding plate 52 form an angle, and the second guiding plate 52 and the third guiding plate 53 form an angle. Among them, the first guiding plate 51 contacts the vehicle body sheet metal 1, the third guiding plate 53 contacts the trim panel extension 22, and a second flanging 54 is provided at the contact end of the third guiding plate 53 and the trim panel extension 22.

[0052] More preferably, the first guiding plate 51 is parallel to the vehicle body sheet metal 1, and the third guiding plate 53 is perpendicular to the trim panel extension 22.

[0053] By providing a side curtain airbag guiding structure that can be driven by a driving device, the present invention enables the side curtain airbag guiding structure to have a starting position and an airbag guiding position. At the starting position, the side curtain airbag guiding structure is far from the side curtain airbag, thereby reducing the distance from the trim panel main body, reducing the overall space of the airbag guiding structure, leaving enough space for the ceiling, wiring harness, personal lights, etc. in the side curtain airbag area to meet the design requirements of a large interior space in the vehicle. When it is necessary to inflate the side curtain airbag, the side curtain airbag guiding structure approaches the side curtain airbag, providing a guiding function for the side curtain airbag, enabling the side curtain airbag to be guided and extended into the occupant compartment to protect the occupants.

[0054] In one of the embodiments, the first end of the side curtain airbag guiding structure 5 contacts the vehicle body sheet metal 1, and the second end extends towards the trim panel extension 22. When the side curtain airbag guiding structure 5 moves to the airbag guiding position, the second end contacts the ceiling 3 and drives the ceiling 3 to separate from the trim panel extension 22.

[0055] Specifically, the position of the side air curtain guiding structure 5 can be defined according to the second end where the side air curtain guiding structure 5 contacts the trim panel extension 22. When the side air curtain guiding structure 5 moves to the air curtain guiding position, the second end moves to the overlapping point of the trim panel extension 22 and the ceiling 3, and pushes the ceiling 3 open, causing the ceiling 3 to separate from the trim panel extension 22.

[0056] When the ceiling 3 overlaps with the trim panel extension 22, the trim panel extension 22 supports the ceiling 3. When the side air curtain 4 needs to be detonated, by separating the ceiling 3 from the trim panel extension 22, it is possible to prevent the trim panel extension 22 and / or the ceiling 3 from obstructing the extension of the side air curtain 4.

[0057] Among them, the distance between the second end of the side air curtain guiding structure 5 and the trim panel extension 22 is very small. The ceiling 31 overlaps on the trim panel extension 22, and there is a certain gap between the end of the ceiling 31 and the trim panel extension 22. Therefore, when the second end of the side air curtain guiding structure 5 moves to the overlapping point of the trim panel extension 22 and the ceiling 3, the second end of the side air curtain guiding structure 5 is inserted into the gap between the end of the ceiling 31 and the trim panel extension 22, thereby lifting the ceiling 31.

[0058] In this embodiment, when the side air curtain guiding structure moves to the air curtain guiding position, the ceiling is pushed open by the second end of the side air curtain guiding structure, causing the ceiling to separate from the trim panel extension and leaving a gap, so that when the side air curtain is detonated, it can extend from the connection between the ceiling and the second end of the side air curtain guiding structure through the gap to the passenger compartment to protect the safety of the passengers, and at the same time, it also prevents the side air curtain from getting stuck inside the trim panel when detonated.

[0059] As Figure 4 shown, in one embodiment, the side air curtain guiding structure 5 is provided with one or more guiding hooks 501, and the vehicle body sheet metal 1 is provided with one or more vehicle body guiding mechanisms 11 extending along the direction of the vehicle body sheet metal 1. One end of the guiding hook 501 is fixedly connected to the side air curtain guiding structure 5, and the other end is inserted into the vehicle body guiding mechanism 11 and slides along the vehicle body guiding mechanism 11.

[0060] Specifically, Figure 4 It is a schematic view for observing from the outside of the vehicle towards the vehicle body sheet metal. One or more vehicle body guiding mechanisms 11 extending along the vehicle body direction are provided on the vehicle body sheet metal 1. The guiding hook 501 is inserted into the vehicle body guiding mechanism 11 and can slide along the vehicle body guiding mechanism 11, thereby helping the side air curtain guiding structure 5 to move and limiting the side air curtain guiding structure 5 through the vehicle body guiding mechanism 11. When the guiding hook 501 moves to the lowest position of the vehicle body guiding mechanism 11, the side air curtain guiding structure 5 is in the starting position. When the guiding hook 501 moves to the highest position of the vehicle body guiding mechanism 11, the side air curtain guiding structure 5 is in the air curtain guiding position.

[0061] In some embodiments, the vehicle body guiding mechanism 11 is a guiding groove or a guiding rail.

[0062] In some embodiments, the guiding hook 501 is a hook.

[0063] In some embodiments, the guiding hook 501 is fixedly connected to the first guiding plate 51 or the second guiding plate 52.

[0064] Preferably, the vehicle body guiding mechanism 11 is provided on the vehicle body sheet metal of the vehicle body sheet metal 1.

[0065] In this embodiment, the movement of the side air curtain guiding structure is controlled by the vehicle body guiding mechanism, and the maximum movement amount at the top is limited.

[0066] As Figure 5 shown, in one embodiment, the second end of the side air curtain guiding structure 5 extends towards the trim extension 22, one or more trim guiding mechanisms 23 are provided on the inner wall of the trim extension 22 facing the second end of the side air curtain guiding structure 5, and the second end of the side air curtain guiding structure 5 slides along the trim guiding mechanism 23.

[0067] Specifically, as Figure 5 shown, a trim guiding mechanism 23 is provided on the inner wall of the trim extension 22, and the second end of the side air curtain guiding structure 5 slides along the trim guiding mechanism 23. Preferably, the flange 54 of the side air curtain guiding structure 5 is inserted into the trim guiding mechanism 23 and slides along the trim guiding mechanism 23.

[0068] In some embodiments, the trim guiding mechanism 23 is a guiding groove or a guiding rail.

[0069] In this embodiment, the movement of the side air curtain guiding structure is controlled by the trim guiding mechanism, and the maximum movement amount at the top is limited.

[0070] In one embodiment, the driving device 6 includes a variable polarity magnetic structure 61 and a fixed polarity magnetic structure 62, the variable polarity magnetic structure 61 is fixedly connected to the trim body 21, the fixed polarity magnetic structure 62 is fixedly connected to the side air curtain guiding structure 5, the variable polarity magnetic structure 61 faces the fixed polarity magnetic structure 62, and the controller 7 is electrically connected to the variable polarity magnetic structure 61, and the controller 7 outputs current, stops outputting current or changes the direction of the current to the variable polarity magnetic structure 61.

[0071] This embodiment adopts a magnetic drive method. Among them, the variable-polarity magnetic structure 61 includes a variable-polarity magnetic pole base material 611 and a winding coil 612. The controller 7 is electrically connected to the winding coil 612. By changing the current direction of the winding coil 612, the magnetic field polarity direction of the variable-polarity magnetic pole base material 611 is changed. The variable-polarity magnetic pole base material 611 can be an iron core. The magnetic field polarity direction of the fixed-polarity magnetic structure 62 is fixed. For example, a fixed-polarity magnet can be used.

[0072] By changing the magnetic field polarity direction of the variable-polarity magnetic structure 61, the variable-polarity magnetic structure 61 can adsorb or repel the fixed-polarity magnetic structure 62.

[0073] In some embodiments, the variable-polarity magnetic structure 61 is located below the fixed-polarity magnetic structure 62.

[0074] When the magnetic field polarity direction of the variable-polarity magnetic structure 61 is N at the top and S at the bottom, and the magnetic field polarity direction of the fixed-polarity magnetic structure 62 is also N at the top and S at the bottom, the variable-polarity magnetic structure 61 adsorbs the fixed-polarity magnetic structure 62;

[0075] When the magnetic field polarity direction of the variable-polarity magnetic structure 61 is S at the top and N at the bottom, and the magnetic field polarity direction of the fixed-polarity magnetic structure 62 is also S at the top and N at the bottom, the variable-polarity magnetic structure 61 adsorbs the fixed-polarity magnetic structure 62;

[0076] When the magnetic field polarity direction of the variable-polarity magnetic structure 61 is N at the top and S at the bottom, and the magnetic field polarity direction of the fixed-polarity magnetic structure 62 is S at the top and N at the bottom, the variable-polarity magnetic structure 61 repels the fixed-polarity magnetic structure 62;

[0077] When the magnetic field polarity direction of the variable-polarity magnetic structure 61 is S at the top and N at the bottom, and the magnetic field polarity direction of the fixed-polarity magnetic structure 62 is N at the top and S at the bottom, the variable-polarity magnetic structure 61 repels the fixed-polarity magnetic structure 62.

[0078] Since the variable-polarity magnetic structure 61 is fixedly connected to the trim panel main body 21, and the fixed-polarity magnetic structure 62 is fixedly connected to the side curtain airbag guiding structure 5, when the variable-polarity magnetic structure 61 adsorbs the fixed-polarity magnetic structure 62, the side curtain airbag guiding structure 5 remains in the starting position. When the variable-polarity magnetic structure 61 repels the fixed-polarity magnetic structure 62, the side curtain airbag guiding structure 5 is driven by the fixed-polarity magnetic structure 62 to move from the starting position before movement towards the side curtain airbag 4 to the airbag guiding position after movement. The ceiling 3 also moves from the position where it overlaps with the trim panel extension part 22 before the movement of the side curtain airbag guiding structure 5 and is pushed open by the side curtain airbag guiding structure 5 after the movement of the side curtain airbag guiding structure 5.

[0079] Such as Figure 6The following is a schematic structural diagram of a vehicle side airbag installation mechanism according to another embodiment of the present invention, including: a vehicle body sheet metal 1, a trim panel 2, and a roof panel 3. The trim panel 2 includes a trim panel main body 21 fixedly connected to the vehicle body sheet metal 1. The trim panel main body 21 is provided with a trim panel extension portion 22 extending towards the roof panel 3. The end of the trim panel extension portion 22 is lapped with the roof panel 3. The vehicle body sheet metal 1, the trim panel 2, and the roof panel 3 are connected to enclose a side airbag accommodation space for accommodating the side airbag 4. It further includes a side airbag guiding structure 5 and a driving device 6. The side airbag guiding structure 5 is arranged in the side airbag accommodation space and is located between the side airbag 4 and the trim panel main body 21. The driving end of the driving device 6 is connected to the side airbag guiding structure 5, and the driving device 6 is electrically connected to a controller 7. The controller 7 controls the driving device 6 to drive the side airbag guiding structure 5 to remain in the starting position or move towards the side airbag 4 to the airbag guiding position in the side airbag accommodation space. When in the starting position, the distance between the side airbag guiding structure 5 and the side airbag 4 is a first distance, and when in the airbag guiding position, the distance between the side airbag guiding structure 5 and the side airbag 4 is a second distance, and the first distance is greater than the second distance. The driving device 6 includes a motor 63 and a push rod 64 driven by the motor 63. The push rod 64 is fixedly connected to the side airbag guiding structure 5. The controller 7 is electrically connected to the motor 63. The controller 7 outputs current to the motor 63, stops outputting current, or changes the direction of the current.

[0080] In this embodiment, it is a motor drive mode. The motor 63 is fixed on the trim panel 2 or the vehicle body sheet metal 1. For example, the motor 63 is fixed on the trim panel main body 21. When the controller 7 outputs current to the motor 63, the motor 63 drives the push rod 64 to move towards or away from the side airbag 4. By changing the direction of the current, the movement direction of the push rod 64 will be changed. At the same time, when the controller 7 stops outputting current to the motor 63, the motor 63 will stop driving the push rod 64. Specifically, the motor 63 drives the push rod 64 located in the guide sleeve 66 to move through a transmission mechanism 65, drives the push rod 64 from the retracted position to the extended position, and drives the side airbag guiding structure 5 to move from the starting position before movement to the airbag guiding position after movement. The roof panel 3 is also lapped with the trim panel extension portion 22 before the side airbag guiding structure 5 moves, and is pushed open by the side airbag guiding structure 5 after the side airbag guiding structure 5 moves.

[0081] As Figure 7 The following is a working flowchart of a control method for a vehicle side airbag installation mechanism as described above according to an embodiment of the present invention, including:

[0082] Step S701, continuously monitor the collision signal, and control the driving device 6 to keep the side airbag guiding structure 5 in the starting position;

[0083] Step S702: When a collision signal is detected, control the driving device 6 to drive the side air curtain guiding structure 5 towards the side air curtain 4 to move to the air curtain guiding position, and detonate the side air curtain 4.

[0084] Specifically, the present invention can be applied to an electronic device with processing capabilities in a vehicle, such as an Electronic Control Unit (ECU).

[0085] The electronic device of the vehicle, such as the electronic control unit, executes step S701, continuously monitors the collision signal, and controls the driving device 6 to keep the side air curtain guiding structure 5 in the starting position, so as to reduce the overall space of the air curtain guiding structure and leave enough space for the ceiling, wiring harness, personal lights, etc. in the air bag area of the side air curtain to meet the design requirements of a large space inside the vehicle.

[0086] In some embodiments, when the vehicle acceleration signal, speed signal, and / or door pressure signal exceed a preset threshold, a collision signal is generated.

[0087] Specifically, existing collision signal detection methods can be adopted. The vehicle acceleration signal and vehicle speed signal are obtained through the ACU sensor, the vehicle acceleration signal is obtained through the satellite acceleration sensor, and the pressure signal at the door position is obtained through the door pressure sensor.

[0088] Once the collision signal is detected, step S702 is triggered, controlling the driving device 6 to drive the side air curtain guiding structure 5 towards the side air curtain 4 to move to the air curtain guiding position, providing a guiding function for the side air curtain 4, and at the same time detonating the side air curtain 4, so that the side air curtain can be guided and extended into the passenger compartment to protect the occupants.

[0089] By setting a side air curtain guiding structure that can be driven by a driving device, the side air curtain guiding structure has a starting position and an air curtain guiding position. In the starting position, the side air curtain guiding structure is far from the side air curtain, thereby reducing the distance from the trim panel main body, reducing the overall space of the air curtain guiding structure, and leaving enough space for the ceiling, wiring harness, personal lights, etc. in the air bag area of the side air curtain to meet the design requirements of a large space inside the vehicle. At the same time, by monitoring the collision signal, when the collision signal is detected, the side air curtain guiding structure approaches the side air curtain, providing a guiding function for the side air curtain, so that the side air curtain can be guided and extended into the passenger compartment to protect the occupants.

[0090] Such as Figure 8The following is a flowchart of the working method of a vehicle side air curtain installation mechanism as described above in another embodiment of the present invention. The driving device 6 includes a variable polarity magnetic structure 61 and a fixed polarity magnetic structure 62. The variable polarity magnetic structure 61 is fixedly connected to the trim panel main body 21, and the fixed polarity magnetic structure 62 is fixedly connected to the side air curtain guiding structure 5. The variable polarity magnetic structure 61 faces the fixed polarity magnetic structure 62. The controller is electrically connected to the variable polarity magnetic structure 61. The method includes:

[0091] Step S801, continuously monitor the collision signal, control the variable polarity magnetic structure 61 to adsorb the fixed polarity magnetic structure 62, and keep the side air curtain guiding structure 5 at the starting position;

[0092] Step S802, when a collision signal is detected, control the variable polarity magnetic structure 61 to repel the fixed polarity magnetic structure 62, drive the side air curtain guiding structure 5 to move towards the side air curtain 4 to the air curtain guiding position, and detonate the side air curtain 4.

[0093] Specifically, an electronic device of the vehicle, such as an electronic control unit, executes Step S801 to continuously monitor the collision signal, control the variable polarity magnetic structure 61 to adsorb the fixed polarity magnetic structure 62, and keep the side air curtain guiding structure 5 at the starting position, so as to reduce the overall space of the air curtain guiding structure and leave enough space for the ceiling, wiring harness, personal lights, etc. in the side air curtain airbag area to meet the design requirements of a large interior space.

[0094] Among them, the controller 7 can not output current to the variable polarity magnetic structure 61, and then the fixed polarity magnetic structure 62 can directly adsorb to the variable polarity magnetic structure 61. The fixed polarity magnetic structure 62 can be a fixed polarity magnet, and the variable polarity magnetic structure 61 includes a variable polarity magnetic pole substrate 611 and a winding coil 612. The controller 7 is electrically connected to the winding coil 612. When the controller 7 does not output current, the fixed polarity magnetic structure 62 can directly adsorb the variable polarity magnetic pole substrate 611.

[0095] In addition, the controller 7 can also output current to the variable polarity magnetic structure 61, so that the variable polarity magnetic structure 61 outputs current to adsorb the fixed polarity magnetic structure 62.

[0096] In some embodiments, the variable polarity magnetic structure 61 is located below the fixed polarity magnetic structure 62.

[0097] If the magnetic field polarity direction of the fixed-polarity magnetic structure 62 is N at the top and S at the bottom, then by changing the current direction, it is possible to control the magnetic field polarity direction of the variable-polarity magnetic structure 61 to be N at the top and S at the bottom, so that the variable-polarity magnetic structure 61 adsorbs the fixed-polarity magnetic structure 62; or

[0098] If the magnetic field polarity direction of the fixed-polarity magnetic structure 62 is S at the top and N at the bottom, then by changing the current direction, it is possible to control the magnetic field polarity direction of the variable-polarity magnetic structure 61 to be S at the top and N at the bottom, and the variable-polarity magnetic structure 61 adsorbs the fixed-polarity magnetic structure 62.

[0099] Once the collision signal is detected, step S802 is triggered to control the variable-polarity magnetic structure 61 to repel the fixed-polarity magnetic structure 62, driving the side airbag guide structure 5 towards the side airbag 4 to the airbag guiding position, providing a guiding function for the side airbag 4, and at the same time detonating the side airbag 4 so that the side airbag can be guided and extended into the occupant compartment to protect the occupants.

[0100] In some embodiments, the variable-polarity magnetic structure 61 is located below the fixed-polarity magnetic structure 62.

[0101] If the magnetic field polarity direction of the fixed-polarity magnetic structure 62 is S at the top and N at the bottom, then by changing the current direction, the magnetic field polarity direction of the variable-polarity magnetic structure 61 is controlled to be N at the top and S at the bottom, so that the variable-polarity magnetic structure 61 repels the fixed-polarity magnetic structure 62, and the fixed-polarity magnetic structure 62 moves away from the variable-polarity magnetic structure 61;

[0102] If the magnetic field polarity direction of the fixed-polarity magnetic structure 62 is N at the top and S at the bottom, then by changing the current direction, the magnetic field polarity direction of the variable-polarity magnetic structure 61 is controlled to be S at the top and N at the bottom, so that the variable-polarity magnetic structure 61 repels the fixed-polarity magnetic structure 62, and the fixed-polarity magnetic structure 62 moves away from the variable-polarity magnetic structure 61.

[0103] By controlling the magnitude of the current, the magnitude of the repulsive force is changed, thereby driving the side airbag guide structure 5 towards the side airbag 4 to the airbag guiding position.

[0104] In this embodiment, by outputting current to the variable-polarity magnetic structure, stopping the output of current, or changing the direction of the current, the variable-polarity magnetic structure is enabled to adsorb or repel the fixed-polarity magnetic structure, so that the side air curtain guiding structure has a starting position and an air curtain guiding position. At the starting position, the side air curtain guiding structure is far from the side air curtain, thereby reducing the distance from the main body of the trim panel, reducing the overall space of the air curtain guiding structure, and leaving enough space for the ceiling, wiring harness, personal lamp, etc. in the side air curtain airbag area to meet the design requirements of a large interior space in the vehicle. At the same time, by monitoring the collision signal, when the collision signal is detected, the side air curtain guiding structure approaches the side air curtain to provide a guiding function for the side air curtain, so that the side air curtain can be guided and extended into the occupant compartment to protect the occupants.

[0105] As Figure 9 shown in the best embodiment of the present invention, a working flowchart of a control method for a vehicle side air curtain installation mechanism adopting a magnetic attraction drive method is as follows: Figure 3 shown, and it includes:

[0106] Step S901, detecting the ACU / door pressure / satellite sensor signal;

[0107] Step S902, the ACU control box calculates and determines whether the speed / acceleration / pressure exceeds the threshold. If so, execute Step S903; otherwise, execute Step S906;

[0108] Step S903, the ACU control box outputs a negative current (and maintains it until the collision ends), with the S pole on the top and the N pole on the bottom of the variable-polarity magnetic structure. At the same time, the ACU control box outputs a signal to detonate the side air curtain;

[0109] Step S904, the two magnetic poles repel each other with the same polarity, and the side air curtain guiding structure moves upward along the chute to the air curtain guiding position and pushes open the ceiling, while the side air curtain unfolds;

[0110] Step S905, power off after the collision ends, and end.

[0111] Step S906, the ACU control box outputs a positive current (or does not input current), with the N pole on the top and the S pole on the bottom of the variable-polarity magnetic structure (or the fixed-polarity magnetic structure directly attracts the base material of the variable-polarity magnetic structure). The two magnetic poles attract each other with different polarities, and the side air curtain guiding structure is firmly adsorbed without crosstalk or abnormal noise, and continue to execute Step S901.

[0112] Specifically, the vehicle side air curtain installation mechanism adopting the magnetic attraction drive method is as Figure 3 shown. Among them:

[0113] The side air curtain guiding structure 5 is similar to the existing independent plastic / metal guiding structure design. It can be adjusted in shape and size according to the shapes and spatial layouts of parts such as the trim panel, ceiling, vehicle body, wiring harness, and personal lamp. However, it is not rigidly connected to the vehicle body sheet metal 1 and the trim panel 2 through bolts or snaps. Instead, it is non-rigidly connected to the vehicle body sheet metal 1 or the pillar trim panel 2 and can move along the guide grooves or rails on the vehicle body sheet metal 1 and the trim panel 2 in a specified direction under the action of force. The side air curtain guiding structure 5 can be of any shape and structure that meets the spatial layout and styling requirements. The material of the side air curtain guiding structure 5 can be hard materials such as plastic and metal. The side air curtain guiding structure 5 can move relative to the sheet metal or the trim panel, and the moving direction and limit are controlled by structures such as claws / rails / guide grooves.

[0114] The fixed-polarity magnetic structure 62 has fixed magnetic poles and is rigidly fixed on the side air curtain guiding structure 5. It can drive the side air curtain guiding structure 5 to move in a specified direction under the action of magnetic force.

[0115] The variable-polarity magnetic structure 61 is a magnet with variable polarity. It can change the magnetic pole direction by providing forward / reverse current from a controller 7, such as an ACU control box, so as to generate an attractive force or a repulsive force on the fixed-polarity magnetic structure 62.

[0116] The controller, preferably an ACU control box, is used to execute the control method of the vehicle side air curtain installation mechanism adopting the magnetic attraction driving method of the present invention, such as executing steps S901 to S906. Specifically, the controller 7 receives signals from the ACU / satellite / door pressure sensor, and judges whether it is necessary to move the side air curtain guiding structure 5 by performing algorithm processing on the signals. If the side air curtain 4 needs to be detonated, it is necessary to move the side air curtain guiding structure 5, and the same judgment logic can be shared with the detonation of the side air curtain 4. If it is necessary to move the side air curtain guiding structure 5, the current direction of the variable-polarity magnetic structure 61 is changed to push up the fixed-polarity magnetic structure 62 and the side air curtain guiding structure 5.

[0117] The ACU / satellite / door pressure sensor is used to collect acceleration / speed / pressure information. These sensors are the sensors required to judge whether the side air curtain is detonated, and there is no need to add new sensors separately. Among them, the ACU sensor detects acceleration and speed signals, the satellite acceleration sensor detects acceleration, and the door pressure sensor detects door pressure and speed signals.

[0118] In this embodiment, when arranging the side air curtain in space, the side air curtain guiding structure can be arranged downward in the blank area between the pillar trim panel and the vehicle body sheet metal (these areas usually have no other uses), providing more space for the ceiling, wiring harness, personal lamp, etc. in the airbag area of the side air curtain. At the same time, the side air curtain guiding structure can reduce the overlap amount between the ceiling and the trim panel during the upward movement, and can reduce the resistance during the deployment of the air curtain.

[0119] As Figure 10 Shown in the following is a flowchart of the working process of a control method for a vehicle side airbag curtain installation mechanism as described above. The driving device 6 includes a motor 63 and a push rod 64 driven by the motor 63. The motor 63 is fixedly connected to the trim panel main body 21, and the push rod 64 is fixedly connected to the side airbag curtain guiding structure 5. The controller is electrically connected to the motor 63. The method includes:

[0120] Step S1001: Continuously monitor the collision signal, and control the motor 63 to remain stationary to keep the side airbag curtain guiding structure 5 at the starting position;

[0121] Step S1002: When a collision signal is detected, control the motor 63 to drive the push rod 64 to move towards the side airbag curtain 4 to the airbag curtain guiding position, and detonate the side airbag curtain 4.

[0122] Specifically, an electronic device of the vehicle, such as an electronic control unit, executes Step S1001, continuously monitors the collision signal, and controls the motor 63 to remain stationary to keep the side airbag curtain guiding structure 5 at the starting position, so as to reduce the overall space of the airbag curtain guiding structure and leave enough space to provide more space for the ceiling, wiring harness, personal lights, etc. in the side airbag curtain area, so as to meet the design requirements of a large interior space of the vehicle.

[0123] Among them, the motor 63 is fixed on the trim panel main body 21. In the case where no collision signal is detected, the controller 7 does not output voltage to the motor, so that the motor 63 does not operate and remains stationary to keep the side airbag curtain guiding structure 5 at the starting position.

[0124] Once a collision signal is detected, Step S1002 is triggered. The controller 7 outputs voltage to the motor 63, and the motor 63 operates to drive the push rod 64 to move towards the side airbag curtain 4 to the airbag curtain guiding position, providing a guiding function for the side airbag curtain 4. At the same time, the side airbag curtain 4 is detonated, so that the side airbag curtain can be guided and extended into the passenger compartment to protect the passengers.

[0125] The moving distance of the push rod 64 can be controlled by the motor 63, so as to drive the side airbag curtain guiding structure 5 to move towards the side airbag curtain 4 to the airbag curtain guiding position.

[0126] In this embodiment, by not outputting current to the motor or outputting current to the motor, the motor is not actuated to drive the push rod or the motor is actuated to drive the push rod, so that the side air curtain guiding structure has a starting position and an air curtain guiding position. When in the starting position, the side air curtain guiding structure is far from the side air curtain, thereby reducing the distance from the main body of the trim panel, reducing the overall space of the air curtain guiding structure, and leaving enough space to provide more space for the ceiling, wiring harness, personal lights, etc. in the side air curtain airbag area to meet the design requirements of a large space inside the vehicle. At the same time, by monitoring the collision signal, when the collision signal is detected, the side air curtain guiding structure approaches the side air curtain to provide a guiding function for the side air curtain, so that the side air curtain can be guided and extended into the occupant compartment to protect the occupants.

[0127] As Figure 11 shown in the best embodiment of the present invention, a working flowchart of a control method for a vehicle side air curtain installation mechanism adopting a motor drive mode is as follows: Figure 6 shown, and includes:

[0128] Step S1101, detecting ACU / door pressure / satellite sensor signals;

[0129] Step S1102, the ACU control box calculates and determines whether the speed / acceleration / pressure exceeds the threshold. If so, execute Step S1103; otherwise, execute Step S1106;

[0130] Step S1103, the ACU control box outputs voltage (and maintains it until the collision ends), the motor is actuated, and at the same time, the ACU control box outputs a signal to detonate the side air curtain;

[0131] Step S1104, the push rod pushes the side air curtain guiding structure to move upward to the air curtain guiding position, and at the same time, the side air curtain unfolds;

[0132] Step S1105, power off when the collision ends, and end.

[0133] Step S1106, the ACU control box does not output voltage, the motor is not actuated, the push rod and the side air curtain guiding structure do not move, and continue to execute Step S1101.

[0134] Specifically, the vehicle side air curtain installation mechanism adopting the motor drive mode is as Figure 6 shown. Among them:

[0135] The side air curtain guiding structure 5 is similar to the existing independent plastic / metal guiding structure design. It can be adjusted in shape and size according to the shapes and spatial layouts of parts such as trim panels, ceilings, vehicle bodies, wire harnesses, and personal lights. However, it is not rigidly connected to the vehicle body sheet metal 1 and the trim panel 2 by bolts or snaps. Instead, it is non-rigidly connected to the vehicle body sheet metal 1 or the pillar trim panel 2 and can move along the guide grooves or rails on the vehicle body sheet metal 1 and the trim panel 2 in a specified direction under the action of force. The side air curtain guiding structure 5 can be of any shape and structure that meets the spatial layout and styling requirements. The material of the side air curtain guiding structure 5 can be hard materials such as plastic and metal. The side air curtain guiding structure 5 can move relative to the sheet metal or the trim panel, and the moving direction and limit are controlled by structures such as claws / rails / guide grooves.

[0136] The driving device 6 in this embodiment is an electric push rod. The driving device 6 in this embodiment includes structures such as a motor 63, a transmission mechanism 65, a guide sleeve 66, and a push rod 64. The upper end of the push rod 64 is connected to the side air curtain guiding structure 5, and the lower end of the motor 63 is fixed on the trim panel 2 or the vehicle body sheet metal 1. When the current changes, the push rod 64 extends to generate an upward thrust or contracts to generate a downward contraction force, thereby pushing the side air curtain guiding structure 5 to move in a specified direction.

[0137] The controller 7 is preferably an ACU control box and is used to execute the control method of the vehicle side air curtain installation mechanism using the motor drive mode, such as executing steps S1101 to S1106. Specifically, the controller 7 receives signals from the ACU / satellite / door pressure sensors, and judges whether it is necessary to move the side air curtain guiding structure 5 by performing algorithm processing on the signals. If the side air curtain 4 needs to be detonated, it is necessary to move the side air curtain guiding structure 5, and the same set of judgment logics can be shared with the detonation of the side air curtain 4. If it is necessary to move the side air curtain guiding structure 5, a voltage is applied to the motor 63 of the electric push rod to push up the push rod 64 structure, thereby pushing the side air curtain guiding structure 5 to move upward.

[0138] The ACU / satellite / door pressure sensors are used to collect acceleration / speed / pressure information. These sensors are the sensors required to judge whether the side air curtain is detonated, and there is no need to add new sensors separately. Among them, the ACU sensor detects acceleration and speed signals, the satellite acceleration sensor detects acceleration, and the door pressure sensor detects door pressure and speed signals.

[0139] In this embodiment, when arranging the side air curtain space, the side air curtain guiding structure can be arranged downward in the blank area between the pillar trim panel and the vehicle body sheet metal (these areas usually have no other uses), providing more space for the ceiling, wire harness, personal lights, etc. in the airbag area of the side air curtain. At the same time, the side air curtain guiding structure can reduce the overlap amount between the ceiling and the trim panel during the upward movement, and can reduce the resistance during the deployment of the air curtain.

In some embodiments, the memory 1202 may optionally include a memory remotely provided relative to the processor 1201, and these remote memories may be connected to the device executing the control method of the vehicle side airbag installation mechanism through a network.

[0151] In the present invention, by providing a side airbag guiding structure that can be driven by a driving device, the side airbag guiding structure has a starting position and an airbag guiding position. In the starting position, the side airbag guiding structure is far from the side airbag, thereby reducing the distance from the trim panel main body, reducing the overall space of the airbag guiding structure, leaving enough space for the ceiling, wiring harness, personal lights, etc. in the side airbag area to meet the design requirements of a large space inside the vehicle. At the same time, by monitoring the collision signal, when the collision signal is detected, the side airbag guiding structure approaches the side airbag to provide a guiding function for the side airbag, so that the side airbag can be guided to extend into the occupant compartment to protect the occupants.
