Abstract

The invention relates to a pop-up protection device, a seat and a vehicle. The pop-up protection device comprises a mounting framework, a telescopic assembly and a supporting net. The telescopic assembly is connected to the mounting framework, an included angle is formed between the telescopic direction of the telescopic assembly and the plane where the mounting framework is located, and the telescopic assembly can extend when being impacted; the supporting net is connected with the telescopic assembly and the installation framework, so that when the telescopic assembly extends, the supporting net is stressed to deform, and a buffer space defined by the installation framework, the telescopic assembly and the supporting net is formed. According to the scheme, the upper trunk of the passenger can be driven to twist towards the inner side of the vehicle, so that the risk that the front side, with relatively weak chest rigidity, of the passenger directly participates in collision during collision is avoided by adjusting the body posture of the passenger in the early stage of side column collision; and a certain collision buffering space can be formed between the trunk and the vehicle door, so that the collision strength between the trunk of the passenger and the vehicle door plate is relieved.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a pop-up protection device, a seat and a vehicle. BACKGROUND

[0002] In a vehicle side collision accident, especially in a side impact column working condition, excessive intrusion of the B-pillar and the door panel structure will directly threaten the occupant survival space. Collision test data shows that when the impact point is located in the B-pillar area, the upper torso (including the shoulder and ribs) and the pelvic area of the front-row occupant will bear significant impact load. Among them, due to the compression of the chest upper ribs by the arms during the collision process, the risk of rib fracture in this area is significantly increased.

[0003] The current mainstream protection scheme adopts a side airbag device arranged outside the seat side wing, which buffers the contact intensity of the occupant and the door trim panel through airbag deployment. Specifically, the side airbag tries to lift the occupant's arms upward during deployment to alleviate the squeezing effect of the arms on the chest.

[0004] However, it is found in actual application that this scheme has two technical defects: first, there is a dynamic matching deviation between the airbag deployment timing and the door intrusion deformation, resulting in insufficient stability of the arm lifting action; second, when the occupant's body is externally rotated due to the collision effect, the chest protection area changes from the chest side with high rigidity to the chest front side with weak rigidity, at which time the supporting rigidity of the side airbag cannot adapt to the change of the stress position, and the protection efficiency is significantly reduced. SUMMARY

[0005] Therefore, it is necessary to provide a pop-up protection device, a seat and a vehicle to solve the problems that in a side impact column accident of a passenger vehicle, the arms squeeze the chest during the collision, the occupant's torso is laterally twisted, the chest injury is relatively aggravated, and the excessive intrusion of the B-pillar and the door panel increases the collision intensity of the occupant.

[0011] In one of the embodiments, the support rod is in an arc structure protruding towards the direction away from the mounting frame.

[0012] In one of the embodiments, the telescopic assembly further comprises an extension rod, which is connected to the top end of the support rod.

[0015] A vehicle comprising a vehicle body with a door, further comprising a seat as claimed in any one of the above embodiments, the seat is located inside the vehicle body, and the pop-up protection device is located on the side of the seat close to the door.

[0016] The pop-up protection device provided in the above scheme has the advantages that the pop-up elongated telescopic assembly is arranged, and the support net connected to the telescopic assembly is arranged, so that the outer side of the support net is pulled out forward at the same time during the pop-up of the telescopic assembly, and the upper torso of the occupant is twisted to the inside of the vehicle by the skin of the side wing part of the seat during the pulling out of the support net, so as to adjust the body posture of the occupant before the side column collision occurs, and avoid the risk that the chest of the occupant is directly involved in the collision when the collision occurs. On the other hand, when the included angle between the support surface and the plane where the mounting framework is located increases, the region space enclosed by the support net, the mounting framework and the telescopic assembly becomes larger, so that a certain collision buffering space is formed between the torso and the door, which can relieve the collision strength between the torso of the occupant and the door panel.

[0029] An embodiment of the present application provides a vehicle, which can be any passenger car without limitation. The vehicle includes a vehicle body provided with a vehicle door, and further includes a seat 10 as any one of the following, the seat 10 being located inside the vehicle body, and a pop-up protection device 100 being located on a side of the seat 10 close to the vehicle door, for popping up to protect the safety of the occupant when the vehicle is hit.

[0030] Referring to Figure 1 , Figure 1 A structural schematic diagram of a seat 10 in an embodiment of the present application is shown, and the seat 10 provided by the embodiment of the present application is applied to the above-mentioned vehicle, but is not limited thereto. As shown in Figure 1As shown, the seat 10 comprises the pop-up protection device 100 as in any of the embodiments described below, further comprises a backrest framework 200 and a skin 300 wrapping the backrest framework 200, the backrest framework 200 is located inside the space enclosed by the skin 300. The mounting framework 110 of the pop-up protection device 100 described below is located in the same plane as the backrest framework 200, and the pop-up protection device 100 is located inside the space enclosed by the skin 300, so that in the normal state, the pop-up protection device 100 is located inside the skin 300 to avoid affecting the normal use of the seat 10. When the telescopic assembly 120 in the pop-up protection device 100 described below is extended, it can drive the skin 300 to deform and / or the telescopic assembly 120 to partially extend out of the skin 300, thereby avoiding the limitation of the skin 300 interfering with the protection effect of the pop-up protection device 100 on the occupant. Exemplarily, in this embodiment, when the telescopic assembly 120 is extended, it can tear the skin 300 to partially extend out of the skin 300, but this is not as a limitation.

[0031] In combination Figure 2 As shown, Figure 2 A side sectional view of the seat 10 in an embodiment of the present application is shown, in one embodiment, the seat 10 comprises a backrest part 400 and side wing parts 500 located on both sides of the backrest part 400. It can be understood that the side wing parts 500 are usually located on both sides of the occupant in the predetermined seating position, and the pop-up protection device 100 is arranged on one of the two side wing parts 500, so that when the vehicle is impacted, the pop-up protection device can pop up on one side of the occupant, thereby achieving the effect of protecting the occupant from the side. Specifically, when the seat 10 is installed inside the vehicle body, the pop-up protection device 100 is arranged on the side wing part 500 close to the door.

[0032] As Figure 1 and Figure 2 As shown, the seat 10 further comprises a headrest part 600 located above the backrest part 400 and a seating part 700 arranged at an angle with the backrest part 400, the seating part 700 is used for the occupant to sit, and the headrest part 600 is used to support the head of the occupant.

[0033] As Figure 4 As shown, the seat 10 further comprises a side wing support 800 located inside the skin 300, the side wing support 800 is connected to the backrest framework 200 and is arranged separately from the pop-up protection device 100, and the side wing support 800 and the pop-up protection device 100 are respectively located in two different side wing parts 500 of one seat 10 and respectively support the corresponding side wing parts 500; in other words, when the seat 10 is installed inside the vehicle body, since the pop-up protection device 100 is arranged on the side wing part 500 close to the door, the side wing support 800 is correspondingly arranged on the other side wing part 500.

[0034] Combination Figure 3 and Figure 4 As shown, one embodiment of this application also provides a pop-up protective device 100, which includes a mounting frame 110, a telescopic component 120, and a support net 130. Figure 4 As shown, in this embodiment, the mounting frame 110 and the backrest frame 200 of the seat 10 are on the same plane.

[0035] like Figure 2 and Figure 3 As shown, the telescopic component 120 is connected to the mounting frame 110, and the telescopic direction of the telescopic component 120 forms an angle with the plane of the mounting frame 110. The telescopic component 120 is configured to extend upon impact. When the vehicle is impacted, the telescopic component 120 will also be impacted, at which point the telescopic component 120 will automatically extend to protect the occupants. It is understood that "impacted" or "shocked" as mentioned in this specification refers to the force or pressure reaching a set value, and does not mean that it will be triggered by a slight impact. In this embodiment, the telescopic direction of the telescopic component 120 is perpendicular to the plane of the mounting frame 110, but this is not a limitation. In other embodiments, the angle between the telescopic direction of the telescopic component 120 and the plane of the mounting frame 110 can also be other angles close to 90°, which is not limited.

[0036] It is understandable that the extension of the telescopic component 120 needs to be designed according to actual needs, and it is not consistent in different car models or when it is applicable to different occupants, such as family cars, racing cars or children's racing cars, etc. The extension stroke of the telescopic component 120 is not limited here.

[0037] like Figure 1 and Figure 4 As shown, the support net 130 is connected to the telescopic component 120 and the mounting frame 110 respectively, so that when the telescopic component 120 extends, the support net 130 deforms under force and forms a buffer space enclosed by the mounting frame 110, the telescopic component 120 and the support net 130. For illustrative purposes, in... Figure 4 The bold dashed lines in the diagram indicate the deformed portions of the support mesh 130 and skin 300 when the telescopic component 120 extends, while the dashed lines indicate the state of the support mesh 130 and skin 300 when the telescopic component 120 is not extended. Figure 4As shown, when the telescopic assembly 120 is extended, the support net 130 is deformed under force, forming a buffer space surrounded by the mounting framework 110, the telescopic assembly 120 and the support net 130. On the one hand, when the telescopic assembly 120 is extended, i.e. during the ejection process, the support net 130 is pulled out forward at the same time, and during the process of being pulled out forward, the support net 130 twists the upper torso of the occupant inward by the skin 300 of the side wing part 500 of the seat 10, thereby adjusting the body posture of the occupant in the early stage of the side column collision, avoiding the risk that the front side of the occupant with relatively weak chest stiffness directly participates in the collision when the collision occurs. On the other hand, the support net 130, the mounting framework 110 and the telescopic assembly 120 together form a buffer space, which forms a certain collision buffer space between the torso and the door, which will relieve the collision intensity between the torso of the occupant and the door panel.

[0038] Specifically, referring to Figure 4 As shown, the support net 130 is sleeved outside the telescopic assembly 120 and the mounting framework 110, which is equivalent to that the support net 130 is sleeved on both sides of the mounting framework 110 and covers the telescopic assembly 120. For the convenience of description, the side of the mounting framework 110 where the telescopic assembly 120 is installed is defined as the inner side of the mounting framework 110, and the other side is defined as the outer side of the mounting framework 110. When the telescopic assembly 120 is extended, the support net 130 located on the outer side of the mounting framework 110 is forced to tightly adhere to the outer side of the mounting framework 110, and the support net 130 located on the inner side of the mounting framework 110 is stretched and deformed to be pulled out forward along with the extension of the telescopic assembly 120. During the process of being pulled out forward, the support net 130 twists the upper torso of the occupant inward by the skin 300 of the side wing part 500 of the seat 10, thereby adjusting the body posture of the occupant in the early stage of the side column collision, avoiding the risk that the front side of the occupant with relatively weak chest stiffness directly participates in the collision when the collision occurs. In other embodiments, the support net 130 can also partially cover the telescopic assembly 120 and the mounting framework 110, and when the telescopic assembly 120 is extended, the support net 130 is deformed and pulled out forward. The support net 130 can also be fixed on the mounting framework 110 at one side and fixed on the telescopic assembly 120 at the other side, so as to drive the support net 130 to be deformed and pulled out forward when the telescopic assembly 120 is extended. The specific content is not described here.

[0039] In the present embodiment, the support net 130 is a steel wire net, but is not limited thereto, and in other embodiments, the support net 130 can also be a net structure made of other metal materials or other materials.

[0040] As Figure 3As shown, in one embodiment, the telescopic assembly 120 comprises a sleeve 121 and a push rod 122 connected to each other, the push rod 122 is slidably connected to the sleeve 121, the sleeve 121 is connected to the mounting frame 110, and the supporting net 130 is connected to the end of the push rod 122 away from the sleeve 121. When the push rod 122 slides along the sleeve 121 towards the direction away from the mounting frame 110, the telescopic assembly 120 is elongated.

[0041] As shown, Figure 3 In one embodiment, the telescopic assembly 120 further comprises a gas generator 123, which is located in the sleeve 121 and at the end of the sleeve 121 close to the mounting frame 110. The gas generator 123 is configured to generate gas to drive the push rod 122 to slide along the sleeve 121 when the vehicle is impacted. In this embodiment, the gas generator 123 is configured to generate gas when the vehicle is impacted at a specific position, so that the gas generator 123 generates a large amount of gas rapidly when the vehicle is impacted at the expected position, and the telescopic assembly 120 is elongated in a very short time due to the inflation of the gas generator 123, thereby protecting the passengers from injury or reducing the degree of injury. It can be understood that the specific impact refers to the impact when the vehicle is impacted at the expected position, and the vehicle side B pillar is taken as an example in this specification. In this embodiment, when the vehicle is impacted at the side B pillar, the on-board electronic control unit (ACU) will send an ignition instruction to the gas generator 123, so that the gas generator 123 generates gas when impacted. In other embodiments, the gas generator 123 can also generate gas when the vehicle is impacted at a pressure reaching a set value.

[0042] As shown, Figure 3 In this embodiment, the space where the gas generator 123 is located in the sleeve 121 is a region similar to a closed space, so that when the gas generator 123 generates gas, the gas pressure can drive the push rod 122 to slide along the sleeve 121 towards the mounting frame 110.

[0043] As shown, Figure 3 In one embodiment, the telescopic assembly 120 further comprises a supporting rod 124 connected to the end of the push rod 122 away from the mounting frame 110 to move with the telescopic assembly 120, so as to increase the area contact between the telescopic assembly 120 and the skin 300 through the supporting rod 124.

[0044] In combination with Figure 4As shown, in the embodiment, the support net 130 is connected to the support rod 124, so that the connection area of the support net 130 and the telescopic assembly 120 is larger, and when the telescopic assembly 120 is elongated, the support net 130 can pop up in a larger area, so as to better drive the upper torso of the occupant to twist to the inside of the vehicle, so as to adjust the body posture of the occupant before the side column collision occurs, and avoid the risk that the chest rigidity of the occupant is relatively weak in the front side and directly participates in the collision when the collision occurs; on the other hand, compared with single-point support, the space enclosed by the support net 130, the mounting framework 110 and the telescopic assembly 120 is larger, and a larger collision buffering space can be formed between the torso and the door, and the collision intensity between the torso of the occupant and the door panel can be relieved to a greater extent.

[0045] As shown in the embodiment, the support rod 124 is connected to the push rod 122 through a fastener, and the push rod 122 is connected to the telescopic assembly 120. Figure 1 As shown, in the embodiment, the axial direction of the support rod 124 is the same as the longitudinal direction of the seat 10, and it should be noted that the longitudinal direction of the seat 10 refers to the setting direction of the back of the seat 10.

[0046] As shown in the embodiment, the support rod 124 is connected to the push rod 122 through a fastener, and the push rod 122 is connected to the telescopic assembly 120. Figure 3 As shown, in the embodiment, the support rod 124 is connected to the push rod 122 through a fastener, and the push rod 122 is connected to the telescopic assembly 120.

[0047] As shown, in one of the embodiments, the support rod 124 is in an arc-shaped structure protruding outward in the direction away from the mounting framework 110, so as to better adapt to the structural features of the side wing part 500. At the same time, in the embodiment, the support rod 124 is connected to the push rod 122 at the center, and when the support rod 124 moves with the push rod 122 to deform or break through the skin 300, the arc-shaped structure of the support rod 124 makes the stress of the support rod 124 more uniform, so as to obtain a better effect of deforming or breaking through the skin 300. Moreover, since the support rod 124 is in an arc-shaped structure, the part of the support rod 124 located in the armpit area of the vehicle occupant in the predetermined sitting position is inclined at an angle towards the plane where the mounting framework 110 is located, which is more suitable for the angle of the occupant's arm to be inclined and lifted, so as to avoid local extrusion damage to the chest of the occupant during the collision. Figure 3 As shown, in the embodiment, the support rod 124 is connected to the push rod 122 through a fastener, and the push rod 122 is connected to the telescopic assembly 120.

[0048] As shown, in the embodiment, the support rod 124 is connected to the push rod 122 through a fastener, and the push rod 122 is connected to the telescopic assembly 120. Figure 2 As shown, in the embodiment, the support rod 124 is connected to the push rod 122 through a fastener, and the push rod 122 is connected to the telescopic assembly 120. Figure 3 As shown, in one of the embodiments, the telescopic assembly 120 further comprises at least one guide 125, and in the embodiment, the guide 125 is also arranged in the direction perpendicular to the plane where the mounting framework 110 is located. Figure 3As shown, each guide 125 comprises a guide sleeve 1251 and a guide rod 1252 slidingly connected to the guide sleeve 1251, and the support rod 124 is connected to one end of the guide rod 1252 away from the guide sleeve 1251, and the sliding direction of the guide rod 1252 is the same as the sliding direction of the push rod 122, so that when the push rod 122 drives the support rod 124 to move, the movement of the support rod 124 is more stable under the action of the guide rod 1252, avoiding problems such as swinging.

[0049] In one embodiment, the guide 125 further comprises a limiting piece 1253, which is fixedly connected to the guide sleeve 1251 and the guide rod 1252 to limit the sliding of the guide rod 1252, and when the push rod 122 is elongated, the limiting piece 1253 is broken to release the sliding limitation of the guide rod 1252. On the one hand, when the vehicle is not impacted, the limiting piece 1253 can limit the movement of the guide rod 1252, reducing or limiting the movement of the push rod; on the other hand, when the vehicle is impacted, the limiting piece 1253 can limit the sliding of the guide rod 1252, so that the guide rod 1252 can slide in the guide sleeve 1251, thereby playing a guiding role, so that the movement of the support rod 124 is more stable under the action of the guide rod 1252, avoiding problems such as swinging.

[0050] Specifically, when the vehicle is impacted, the push rod 122 of the telescopic assembly 120 will have a tendency to elongate under the force, which will also drive the support rod 124 to have a tendency to move. When the support rod 124 is forced, it also has a tendency to drive the guide rod 1252 to slide. Since the limiting piece 1253 limits the sliding of the guide rod 1252 at this time, the force will first break the limiting piece 1253 to release the limitation of the guide rod 1252, and then as the push rod 122 is elongated, the support rod 124 is driven to move, and in this process, the guide rod 1252 slides with the movement of the support rod 124, thereby playing a guiding role.

[0051] It is worth mentioning that in the embodiment, the limiting member 1253 can be a pin or the like structure, the pin is at least partially arranged in the guide rod 1252 through the guide sleeve 1251 to limit the sliding of the guide rod 1252 relative to the guide sleeve 1251. When the vehicle is impacted, the push rod 122 (such as the gas generator 123 actuating the push rod) has the tendency to be elongated and transmits the force to the pin through the support rod 124, so that the pin is subjected to the force at least in the sliding direction of the guide rod 1252, which causes the pin to break and release the sliding limitation of the pin on the guide rod 1252. Those skilled in the art should understand that the condition for the pin to break is that the force on the pin at least in the sliding direction of the guide rod 1252 is greater than the force required for the pin to break, which can be achieved by increasing the amount of gas released by the above-mentioned gas generator 123 or reducing the angle required for the pin to break, for example, by providing notches on the pin or a section with a smaller diameter, etc., which are not limited herein.

[0052] As shown in Figure 2 and Figure 3 in the embodiment, the number of guides 125 is two, and the two guides 125 are respectively located on both sides of the sleeve 121 to make the force on the support rod 124 uniform, but not as a limitation, in other embodiments, the number of guides 125 can also be single or more than two.

[0053] In one embodiment, when the telescopic assembly 120 is elongated, the end of the telescopic assembly 120 away from the mounting framework 110 is at least partially located in the armpit area of the vehicle occupant in the predetermined seating position, lifting the occupant's arm to avoid local crushing injury to the occupant's chest during the collision.

[0054] In the embodiment, as shown in Figure 3 , the telescopic assembly 120 further comprises an extension rod 126 connected to the support rod 124, the extension rod 126 is connected to the top end of the support rod 124, and as shown in Figure 2 , the extension rod 126 is located at the end of the support rod 124 away from the seating portion 700 to increase the length of the support rod 124 in the armpit area of the vehicle occupant in the predetermined seating position, thereby achieving a better effect of lifting the occupant's arm.

[0055] In the embodiment, the extension rod 126 is inclined from the end close to the support rod 124 to the end away from the support rod 124 towards the direction close to the plane of the mounting framework 110, thereby forming an inclination angle to facilitate the inclination of the occupant's arm.

[0056] The pop-up protection device 100 provided in the above scheme, when the side impact accident of the vehicle occurs, the electronic control unit (ACU) on the vehicle will send an ignition instruction to the gas generator 123, and the gas generated after the ignition of the gas generator 123 will push the push rod 122 outward, the limiting piece 1253 connected with the guide sleeve 1251 of the guide rod 1252 is sheared off, and the support rod 124 drives the side support net 130 fixed thereon to tear the skin 300 of the side wing part 500 of the seat 10 under the positioning of the guide 125 and then push out forward.

[0057] The pop-up protection device 100 provided in the above scheme, by setting the telescopic assembly 120 that can be popped up and elongated, and setting the support net 130 connected to the telescopic assembly 120, the outer side of the support net 130 will be pulled out forward at the same time during the pop-out process of the telescopic assembly 120, and during the pulling-out process of the support net 130, the upper torso of the occupant will be twisted to the inside of the vehicle by the skin 300 of the side wing part 500 of the seat 10, so as to adjust the body posture of the occupant before the side impact occurs, and avoid the risk that the chest of the occupant is relatively weak and directly participates in the collision; on the other hand, when the included angle between the support surface and the plane where the mounting framework 110 is located increases, the area space enclosed by the support net 130, the mounting framework 110 and the telescopic assembly 120 becomes larger, and a certain collision buffer space can be formed between the torso and the door, which will relieve the collision intensity between the torso of the occupant and the door panel, and at the same time, the telescopic assembly 120 also has the effect of lifting the arms of the occupant, avoiding the local extrusion damage to the chest of the occupant during the collision process.
