The flow-dividing piston is arranged in the first channel and the second channel. When the flow-dividing piston is in the first position, the third channel and the second channel are connected. When the flow-dividing piston is in the second position, the third channel and the first channel are connected.

[0013] The bottom of the first channel and the second channel are provided with connected through grooves, which are parallel to the direction in which the first channel and the second channel extend; one end of the connecting rod passes through the through groove and is connected to the lower end of the flow divider piston.

Detailed Implementation

[0039] This invention addresses the technical problem in existing technologies where airbags are individually configured on seats, making it impossible to install multiple airbags due to space constraints. It provides an integrated smart airbag seat.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] This invention provides an integrated intelligent airbag seat, such as... Figure 1As shown, it mainly includes: a frame 1, a main generator 2, a diversion unit 3, a left head airbag 4, a left chest airbag 5, a right head airbag 6, and a right chest airbag 7. The frame 1 is designed to fit the shape of the seat and serves as the basic support structure for the entire seat. The diversion unit 3 is connected to the frame 1; the frame 1 is a tubular structure with no connection between the left and right sides; the main generator 2 is connected to the diversion unit 3, and the diversion unit 3 can be selectively connected to the inner tube on the left or right side of the frame 1.

[0042] The left head airbag 4 is installed at the top left side of frame 1, and the left chest airbag 5 is installed at the middle left side of frame 1; the right head airbag 6 is installed at the top right side of frame 1, and the right chest airbag 7 is installed at the middle right side of frame 1. The left head airbag 4, left chest airbag 5, right head airbag 6, and right chest airbag 7 are all connected to the inner tube of frame 1. The vehicle MCU is electrically connected to the main generator 2; the main generator 2 generates inflation gas to inflate the corresponding airbags through the connected channels.

[0043] Specifically, such as Figure 1 and Figure 2 As shown, the diversion unit 3 includes: a main base 31, a secondary base 32, a diversion piston 33, a control generator 34, a control piston 35, a connecting rod 36, and a damper 37. The main base 31 is configured as a three-way pipe structure, which in this embodiment is arranged in an inverted "T" shape. The main base 31 has a first channel 31a, a second channel 31b, and a third channel 31c. The first channel 31a and the second channel 31b are connected and are arranged on the same straight line. The third channel 31c is perpendicular to the first channel 31a and the second channel 31b, and is connected to the connection point of the first channel 31a and the second channel 31b. The diversion piston 33 is disposed in the first channel 31a and the second channel 31b, and can move left and right in the first channel 31a and the second channel 31b. The diversion piston 33 is usually placed in the first channel 31a. When the diverting piston 33 is in the first position within the first channel 31a, the third channel 31c and the second channel 31b are connected; when the diverting piston 33 is in the second position within the second channel 31b, the third channel 31c and the first channel 31a are connected. The diverting piston 33 can be configured as an isosceles trapezoidal structure that is narrower at the top and wider at the bottom. The isosceles trapezoidal structure can not only play a better role in diverting the flow, but also reduce the amount of material used to reduce costs.

[0044] The bottom of the first channel 31a and the second channel 31b are provided with connected through grooves, which are parallel to the direction of extension of the first channel 31a and the second channel 31b; one end of the connecting rod 36 passes through the through groove and is connected to the lower end of the flow divider piston 33, and the connecting rod 36 can move left and right in the through groove.

[0045] The secondary base 32 is connected to the main base 31 and is configured as a tubular structure. The control piston 35 is located inside the secondary base 32 and is fixedly connected to the other end of the connecting rod 36. A control generator 34 is provided on the left side of the control piston 35. A damper 37 is provided on the right side of the control piston 35. The damper 37 is used to limit the position of the control piston 35 under normal conditions and prevent the control piston 35 from entering the right side of the secondary base 32. For example, the damper 37 can be made of metal or plastic sheet, which can limit the position of the control piston 35 under normal conditions.

[0046] The first channel 31a of the main base 31 is used to connect to the left side of the frame 1, the first channel 31b of the main base 31 is used to connect to the right side of the frame 1, and the third channel 31c of the main base is used to connect to the main generator 2.

[0047] like Figure 1 and Figure 2 As shown, in specific applications, the first channel 31a of the main base 31 is threaded to the left side of the frame 1, the second channel 31b of the main base 31 is threaded to the right side of the frame 1, and the third channel 31c of the main unit is threaded to the main generator 2. When a vehicle collision occurs, if the car MCU recognizes a right-side collision signal, the main generator 2 receives an ignition command and is triggered to generate gas. The gas passes through the third channel 31c and the second channel 31b of the diversion unit 3 and enters the right-side inner tube of the frame 1, inflating the right-side head airbag 6 and the right-side chest airbag 7 located on the right side of the frame 1. The right-side head airbag 6 and the right-side chest airbag 7 quickly deploy to protect the occupants. If the ACU detects a left-side collision signal, the control generator 34 first receives the ignition command and begins inflation. The gas pushes the control piston 35 to the right and overcomes the damping 37. The control piston 35 then drives the diversion piston 33 to move to the right via the connecting rod 36. The main generator 2 receives the ignition command and triggers the generation of gas. The gas passes through the third channel 31c and the first channel 31a of the diversion unit 3 in sequence and enters the left inner tube of the frame 1, inflating the left head airbag 4 and the left chest airbag 5 located on the left side of the frame 1. The left head airbag 4 and the left chest airbag 5 quickly deploy to protect the occupants.

[0048] like Figure 2As shown, to further ensure the airtightness of the diversion piston 33 and prevent gas from overflowing through it, in a preferred embodiment of the present invention, the diversion unit 3 further includes a first sealing ring 38 and a second sealing ring 39. The first sealing ring 38 is connected to the upper end of the diversion piston 33 and is used to tightly fit with the upper inner wall of the first channel 31a. The second sealing ring 39 is connected to the lower end of the diversion piston 33 and is used to tightly fit with the lower inner walls of the first channel 31a and the second channel 31b. To ensure a sealing effect, the first sealing ring 38 and the second sealing ring 39 can each be configured as two sealing rings.

[0049] Similarly, to further ensure the airtightness of the control piston 35 and prevent gas from overflowing through it, in a preferred embodiment of the present invention, the diversion unit 3 further includes a third sealing ring 310 and a fourth sealing ring 311. The third sealing ring 310 is connected to the upper end of the control piston 35 and is used to tightly fit with the upper inner wall of the sub-base 32; the fourth sealing ring 311 is connected to the lower end of the control piston 35 and is used to tightly fit with the lower inner wall of the sub-base 32. To ensure a sealing effect, the third sealing ring 310 and the fourth sealing ring 311 can each be configured as two sealing rings.

[0050] In embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the left head airbag 4, left chest airbag 5, right head airbag 6, and right chest airbag 7 have the same structure, each including: airbag / air bag 8, inflatable end, and dust cover 9. The airbag / air bag 8 is folded and sewn together with stitches 10; one end of the inflatable end is connected to the airbag / air bag 8, and the other end is used to connect to the inner tube of the frame 1; each airbag / air bag 8 has at least one inflatable end. When multiple inflatable ends are provided on the airbag / air bag 8, their even distribution improves the inflation efficiency of the airbag / air bag 8. The dust cover 9 is fitted over the outside of the airbag / air bag 8. Both ends of the dust cover 9 and the airbag / air bag 8 are fixed to the frame 1 by snap rings; this snap-fit ​​connection method has the advantages of convenient, reliable, and low-cost connection.

[0051] The integrated intelligent airbag seat provided in this embodiment of the invention has at least the following beneficial effects or advantages:

[0052] The integrated intelligent airbag seat provided in this invention features a shunt unit connected to a frame. The frame is a tubular structure with separate left and right sides. A main generator is connected to the shunt unit, which can selectively connect to either the inner tube on the left or right side of the frame. When the vehicle's MCU detects a collision on the left or right side, it controls the corresponding side's inflation line to connect. Gas generated by the main generator enters the corresponding airbag through the connected line and inflates it. This integrated intelligent airbag seat inflates four airbags using a single main generator, eliminating the need for a separate generator for each airbag and reducing installation space. Therefore, multiple airbags can be installed in the seat, providing protection for multiple parts of the occupant's body.

[0053] The integrated intelligent airbag seat provided in this embodiment of the invention features airbag zone control on the left and right sides. It can trigger the airbag on the corresponding side of the seat individually after recognizing a collision on a certain side of the vehicle, thus avoiding triggering the airbag on the side where no accident occurred and achieving precise protection for the occupants.

[0054] The integrated intelligent airbag seat provided in this embodiment of the invention has head airbags and chest airbags mounted on the seat frame, which can rotate synchronously with the seat. Compared with side curtain airbags mounted on the roof of the vehicle, this design is more adaptable to the future development of rotating seats in automobiles.
