DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the protection scope of the present application.

[0024] Reference to "an embodiment" in this text means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification is not necessarily all referring to the same embodiment, nor is it necessarily referring to a particular alternative embodiment or set of alternative embodiments. It will be explicitly understood that the embodiments described herein can be combined with other embodiments.

[0025] The auxiliary instrument panel assembly, the interior assembly and the vehicle provided by the present application are described in detail below with reference to the embodiments.

[0026] Please refer to Figures 1 to 3 , Figure 1 is a first structural schematic view of an embodiment of the interior assembly of the present application; Figure 2 is a second structural schematic view of an embodiment of the interior assembly of the present application; Figure 3 is a structural schematic view of an embodiment of the airbag of the present application. The present application provides an auxiliary instrument panel assembly 100. The auxiliary instrument panel 1 can be installed between two seats 201 of a vehicle (not shown in the figure) and fixedly connected with the floor of the vehicle. The auxiliary instrument panel assembly 100 comprises the auxiliary instrument panel 1, the airbag 2 and the airbag inflator 3. The auxiliary instrument panel 1 comprises a top surface 11 and a side surface 12. The top surface 11 is the side of the auxiliary instrument panel 1 that is higher along the height direction of the vehicle, and the top surface 11 can be parallel to the floor of the vehicle body. The side surface 12 is arranged adjacent to the top surface 11. The airbag 2 is arranged in the auxiliary instrument panel 1. The airbag inflator 3 is arranged in the auxiliary instrument panel 1. The airbag inflator 3 is connected with the airbag 2. The airbag inflator 3 is used to inflate the airbag 2. When the vehicle collides, the airbag inflator 3 immediately works to generate a large amount of gas, the airbag 2 is inflated by the large amount of gas in a short time and is ejected and deployed from the auxiliary instrument panel 1, and the working principle of the airbag inflator 3 is well known in the art, which will not be described here.

[0027] Among them, at least part of the airbag 2 can be ejected and deployed from the top surface 11 along the first direction X after being inflated, and at least another part can be ejected and deployed from the side surface 12 along the second direction Y. The first direction X can be a direction substantially upward along the height of the vehicle. That is, the airbag 2 is at least partially ejected upward. The first direction X can be completely parallel to the height direction of the vehicle, or can form a certain angle with the height of the vehicle. For example, the airbag 2 can be vertically and obliquely backward or obliquely forward relative to the height direction of the vehicle. After the airbag 2 is at least partially deployed along the first direction X, it can be used to protect the head or the torso of the occupant. The first direction X intersects the second direction Y. The angle between the first direction X and the second direction Y can range from 75 degrees to 105 degrees, or can range from 60 degrees to 120 degrees. The second direction Y can be a horizontal direction substantially along the width of the vehicle. That is, the airbag 2 is at least partially ejected horizontally. The second direction Y can be completely parallel to the width direction of the vehicle, or can form a certain angle with the width of the vehicle. For example, the airbag 2 can be horizontally obliquely forward relative to the width direction of the vehicle. After the airbag 2 is at least partially deployed along the second direction Y, it can be used to protect the knees, the torso, etc. of the occupant.

[0028] By the above arrangement, the airbag 2 is arranged in the auxiliary instrument panel 1, effectively utilizing the space in the auxiliary instrument panel 1, increasing the flexibility of design, and not easily restricted by the performance of the airbag 2 due to insufficient space. In addition, the airbag 2 can be inflated and ejected and unfolded along the first direction X and the second direction Y, so that the airbag 2 can provide protection from more angles, for example, the head, knees and other positions can be protected at the same time, which is beneficial to improve the protection performance when the vehicle collides.

[0029] Please refer to Figures 4 to 5 , Figure 4 is a third structural schematic diagram of an embodiment of the interior assembly of the present application; Figure 5 is Figure 4 is a cross-sectional view of A-A shown in FIG. 1. In an embodiment, the side surface 12 includes a first side surface 121 and a second side surface 122 arranged opposite to each other. The first side surface 121 and the second side surface 122 can be arranged opposite to each other. The first side surface 121 and the second side surface 122 are adjacent to the top surface 11. The airbag 2 includes at least a first portion 21, a second portion 22 and a third portion 23, which are all in communication with the airbag inflator 3. The first portion 21, the second portion 22 and the third portion 23 can be in communication with the airbag inflator 3 respectively, or can be in communication with the airbag inflator 3 after being communicated in a common part of the airbag 2. After the airbag 2 is inflated, the first portion 21 is ejected and unfolded from the top surface 11 along the first direction X. The second portion 22 is ejected and unfolded from the first side surface 121 along the second direction Y. The third portion 23 is ejected and unfolded from the second side surface 122 along the third direction Z. The first portion 21, the second portion 22 and the third portion 23 can all be inflated and unfolded after inflation, for protecting different body parts of the occupant respectively. The angle between the third direction Z and the second direction Y is greater than or equal to 120 degrees. The third direction Z is substantially opposite to the second direction Y. The third direction Z can be 180 degrees, so that the second portion 22 and the third portion 23 are ejected in opposite directions. The third direction Z can also be arranged as 120 degrees or the like, so that the second portion 22 and the third portion 23 are ejected in mirror-inclined directions. When the auxiliary instrument panel 1 is arranged between two seats, for example, between the main driver seat and the co-driver seat, the first portion 21 can be used to protect the head region of the main driver seat and the co-driver seat occupant. The second portion 22 can be used to protect the knees of the main driver seat occupant. The third portion 23 can be used to protect the knees of the co-driver seat occupant.

[0030] By the above arrangement, after the airbag 2 is inflated, in addition to the first portion 21 being ejected along the first direction X to improve protection, the second portion 22 and the third portion 23 can also be ejected from both sides along the second direction Y and the third direction Z respectively to provide protection. Through one airbag 2 installation point, multiple protection areas are covered, which is beneficial to improve the protection performance.

[0031] The included angle between the third direction Z and the second direction Y can be set according to actual conditions, for example, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 180 degrees, etc., which is not limited here.

[0032] In an embodiment, the sub-instrument panel 1 further comprises a front end 13 and a rear end 14. The front end 13 is a side of the sub-instrument panel 1 closer to the front of the vehicle in the front-rear direction of the vehicle. The rear end 14 is a side of the sub-instrument panel 1 closer to the rear of the vehicle in the front-rear direction of the vehicle. The top surface 11 is provided with a first tear zone 111 near the rear end 14. The first side surface 121 is provided with a second tear zone 1211 near the front end 13. The second side surface 122 is provided with a third tear zone 1212 near the front end 13. The first tear zone 111, the second tear zone 1211, and the third tear zone 1212 are all areas that are easier to break than other positions on the outer surface of the sub-instrument panel 1. That is, the first tear zone 111, the second tear zone 1211, and the third tear zone 1212 can be set to have lower strength than other areas of the sub-instrument panel 1.

[0033] When the airbag 2 inflates and expands, the first portion 21 of the airbag 2 abuts against the first tear zone 111, the second portion 22 abuts against the second tear zone 1211, and the third portion 23 abuts against the third tear zone 1212, and respectively breaks or opens the first tear zone 111, the second tear zone 1211, and the third tear zone 1212. The first portion 21 is ejected from the sub-instrument panel 1 by the first tear zone 111. The second portion 22 is ejected from the sub-instrument panel 1 by the second tear zone 1211. The third portion 23 is ejected from the sub-instrument panel 1 by the third tear zone 1212.

[0034] The distances from the second tear zone 1211 and the third tear zone 1212 to the front end 13 can be the same or different. When the first portion 21 is ejected and deployed, since the first tear zone 111 is near the rear end 14, the first portion 21 can be mostly located near the rear end 14 of the sub-instrument panel 1. After the second portion 22 and the third portion 23 are ejected and deployed, they can be mostly located near the front end 13 of the sub-instrument panel 1.

[0035] Through the above arrangement, the first portion 21 is relatively rear after deployment, and the second portion 22 and the third portion 23 are relatively front after deployment, which is more in line with the distribution required for protecting the occupant. For example, when the occupant is in a sitting position, the first portion 21 can be closer to the relatively rear head of the occupant, and the second portion 22 and the third portion 23 can be closer to the relatively front knees of the occupant, which is beneficial to improve the protection performance.

[0036] In an embodiment, when the part of the second portion 22 is ejected by the first side face 121 in the second direction Y, another part of the second portion 22 also extends and expands in a fourth direction U opposite to the first direction X. The fourth direction U can be a direction generally downward in the vehicle height direction. When the part of the third portion 23 is ejected by the second side face 122 in the third direction Z, another part of the third portion 23 extends and expands in the fourth direction U.

[0037] With the above arrangement, the second portion 22 and the third portion 23 can additionally cover the area in the fourth direction U after being ejected, and when the occupant in the vehicle is in a sitting position, the first portion 21 can protect the head in the first direction X, and the second portion 22 and the third portion 23 can enhance the protection of the knees in the fourth direction U, which is beneficial to improve the protection performance.

[0038] The implementation mode of the above-mentioned extension and expansion of the second portion 22 and the third portion 23 in the fourth direction U can be achieved by the structural design of the airbag 2 itself, so that the surface strength of the second portion 22 and the third portion 23 is different in each direction, and the second portion 22 and the third portion 23 are more easily expanded in the fourth direction U. It can also be achieved by designing a limiting structure, so that when the airbag 2 inflates, the limiting structure presses the second portion 22 and the third portion 23, and the second portion 22 and the third portion 23 extend and expand in the fourth direction U.

[0039] In an embodiment, the top face 11 is provided with a reinforcing area corresponding to the second tear zone 1211 and the third tear zone 1212, respectively. After the airbag 2 inflates, the second portion 22 and the third portion 23 respectively abut against the corresponding reinforcing area in the first direction X, and press the gas in the airbag 2 in the fourth direction U.

[0040] Specifically, the reinforcing area is a region with a certain rigidity and is not easy to deform. After the airbag 2 inflates, the second portion 22 and the third portion 23 are ejected and expand in volume, and then the part of the second portion 22 and the third portion 23 extending upward in the first direction X abuts against the corresponding reinforcing area and cannot further expand due to the limiting. The reinforcing area starts to apply a reaction force to the gas in the second portion 22 and the third portion 23, so that the gas moves in the opposite direction towards the fourth direction U, thereby driving the second portion 22 and the third portion 23 to extend and expand in the fourth direction U.

[0041] With the above arrangement, when the second portion 22 and the third portion 23 are ejected and expanded, the part of the second portion 22 and the third portion 23 can accurately extend in the fourth direction U, and the stability is higher.

[0042] In an embodiment, the airbag 2 comprises a first end 24 and a second end 25. That is, the airbag 2 can be long strip-shaped. The first end 24 forms the second portion 22. The second end 25 forms the third portion 23. The first end 24 and the second end 25 are separated by the first portion 21. The first end 24 is located at the first side 121. The second end 25 is located at the second side 122. The airbag 2 extends from the first end 24 to the rear end 14 and wraps around to the second end 25 to be arranged in a ring shape in the dashboard 1. That is, the airbag 2 is arranged to substantially wrap around the dashboard 1. The airbag inflator 3 is arranged at the rear end 14. The airbag inflator 3 can be arranged at a distance from the first end 24 and the second end 25 so that the first end 24 and the second end 25 expand at approximately the same speed. When the airbag inflator 3 inflates the airbag 2, the airbag inflator 3 simultaneously inflates the first end 24 and the second end 25, and the first end 24 rapidly expands to form the second portion 22, and the second end 25 rapidly expands to form the third portion 23. The area between the first end 24 and the second end 25 also rapidly inflates and expands to form the first portion 21.

[0043] By the above arrangement, the airbag 2 substantially wraps around the dashboard 1, so that a larger volume of airbag 2 can be accommodated in the dashboard 1, and after the airbag 2 is ejected, it is also substantially ejected around the dashboard 1, which can provide a larger protection area, and is beneficial to improve the safety performance.

[0044] In an embodiment, the first end 24 is located at the second tear zone 1211. The second end 25 is located at the third tear zone 1212. Thus, when the airbag 2 inflates, the second portion 22 and the third portion 23 expand rapidly after the second tear zone 1211 and the third tear zone 1212, so as to provide protection as soon as possible, which is beneficial to shorten the ejection time of the airbag 2 and improve the protection efficiency.

[0045] In an embodiment, the dashboard 1 is provided with a receiving groove (not shown in the figure). The opening of the receiving groove can be directed towards the top surface 11. The receiving groove extends from the first side 121 to the second side 122 through the rear end 14. The airbag 2 is arranged in the receiving groove. The top surface 11 covers the receiving groove. The first tear zone 111 can at least partially coincide with the receiving groove near the rear end 14. The first portion 21 can directly reach the first tear zone 111 from the receiving groove along the first direction X. The second tear zone 1211 can at least partially coincide with the receiving groove at the first side 121, and the second portion 22 can directly reach the second tear zone 1211 from the receiving groove after inflation. The third tear zone 1212 can at least partially coincide with the receiving groove at the second side 122, and the third portion 23 can directly reach the third tear zone 1212 from the receiving groove after inflation.

[0046] Through the above arrangement, the airbag 2 can be well accommodated in the auxiliary instrument panel 1, and the accommodating groove is arranged around the auxiliary instrument panel 1, so that the airbag 2 can quickly reach the corresponding surface of the auxiliary instrument panel 1 after inflation, and then quickly pop out, and the protection performance is good. In addition, the top cover is provided with an accommodating groove, so that the airbag 2 is completely hidden in the auxiliary instrument panel 1 when not inflated, and the storage is stable and beautiful.

[0047] Another aspect of the present application provides an interior assembly 200. The interior assembly 200 comprises at least two seats 201 and the auxiliary instrument panel assembly 100 in any of the above embodiments. The auxiliary instrument panel assembly 100 in this embodiment is the auxiliary instrument panel assembly 100 described in the above embodiments, which will not be repeated here. The auxiliary instrument panel assembly 100 is arranged between the two adjacent seats 201. For example, it can be arranged between the driver's seat 201 and the front passenger seat 201. The airbag 2 of the auxiliary instrument panel assembly 100 can at least partially pop out from the auxiliary instrument panel 1 in the first direction X after inflation, and unfold to the position corresponding to the head of the occupant of the seat 201. The position corresponding to the head of the occupant of the seat 201 refers to the position of the head of the occupant when the occupant is in a sitting position on the seat 201. At least another part can pop out from the auxiliary instrument panel 1 in the second direction Y and unfold in front of the position corresponding to the knee of the occupant of the seat 201. The position corresponding to the knee of the occupant of the seat 201 refers to the front of the position of the knee of the occupant in the front-rear direction of the vehicle when the occupant is in a sitting position on the seat 201.

[0048] Through the above arrangement, the airbag 2 is arranged in the auxiliary instrument panel 1, effectively utilizing the space in the auxiliary instrument panel 1, increasing the flexibility of design, and not easily restricted by the performance of the airbag 2 due to insufficient space. In addition, the airbag 2 can pop out and unfold in the first direction X and the second direction Y after inflation, so that the airbag 2 can provide protection to the adjacent seat 201 from more angles, for example, the head, knee and other positions can be protected at the same time, which is beneficial to improve the protection performance of the vehicle in a collision.

[0049] Another aspect of the present application provides a vehicle. The vehicle comprises the interior assembly 200 in any of the above embodiments. The interior assembly 200 in this embodiment is the interior assembly 200 described in the above embodiments, which will not be repeated here. Therefore, by arranging the airbag 2 in the space of the auxiliary instrument panel 1, the interior space of the vehicle is better utilized, the flexibility of design is increased, and the protection effect is better.
