Description
Technical Field
[0001] The utility model relates to the technical field of vehicle occupant protection devices, in particular to an occupant protection device and a vehicle. Background Art
[0002] Airbags have been widely used in the safety restraint system of automobiles. When the vehicle encounters a frontal collision or a side collision, the airbag can restrain, cushion and protect the passengers. However, when the vehicle encounters a rear collision while driving, if the passengers in the car are not wearing seat belts or the children are not using child safety seats, they are likely to be thrown onto the side glass, rear window or sunroof of the car, collide with the glass window, and even break the glass and be thrown out of the car, causing serious safety incidents.
[0003] In order to protect the passengers, a passenger protection device for automobile glass windows has been specifically proposed, which can cushion the collision between the passengers and the window glass when the vehicle is in a rear-end collision. However, the passenger protection device in the related art mainly relies on guide rails for deployment. The two guide rail devices have more stringent requirements and utilization of space, resulting in the inability to apply and expand to other windows. At the same time, the airbag relies on the inflation tendency of the airbag itself and the height difference of the guide rail structure to achieve deployment and arrangement on the car window. The stability and consistency of the deployment process cannot be reliably guaranteed, thereby failing to reduce the damage to the passengers. Utility Model Content

DETAILED DESCRIPTION
[0027] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.
[0028] In the present invention, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the outline of the part itself. In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another and do not have order or importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.
[0029] like Figure 1-Figure 4 As shown, the first aspect of the utility model provides an occupant protection device for a vehicle, comprising: a protection structure 1 and a driving structure 2, wherein the protection structure 1 is arranged on at least one side of the vehicle window, and the protection structure 1 is configured to be able to be pulled and then unfolded to form a protection area that at least partially covers the window; the driving structure 2 includes a cable 21 and a driving member 22 for driving the cable 21 to be retracted, the cable 21 is fixedly connected to the protection structure 1, and the driving member 22 retracts the cable 21 to make the protection structure 1 unfold.
[0030] Through the above technical solution, the cable 21 of the driving structure 2 is fixedly connected to the protective structure 1, and the driving member 22 reels the cable 21 to unfold the protective structure 1 to form a protective area that at least partially covers the window. Therefore, when the vehicle collides or foreign objects fly into the window from the outside, the setting of the protective structure 1 can not only timely protect the occupants from direct collision with the window glass and prevent the occupants from being thrown out, but also prevent foreign objects from passing through the window into the vehicle and hitting the occupants. Therefore, the protective area formed by the unfolding of the protective structure 1 can protect the occupants, thereby improving safety.
[0031] It should be noted that the vehicle windows in the present invention may refer to some windows in the vehicle body structure that may allow passengers to pass through, such as front windows, side windows, rear windows or sunroof windows. The protective structure 1 preferably covers the entire window area, so that when a collision occurs, it can prevent people in the vehicle from directly colliding with the window glass and prevent passengers in the vehicle from being thrown out of the vehicle. At the same time, the protective area formed by the protective structure 1 can intercept foreign objects outside the cabin. For example, a vehicle millimeter wave radar can be added to the vehicle to detect whether there are foreign objects approaching the window. Of course, in order for the protective structure 1 to be able to unfold in a stable shape, some guide rail structures can also be added to the window frame to enable the protective structure 1 to unfold along the contour of the guide rail.
[0032] In some feasible embodiments, in order to facilitate the unfolding of the protective structure 1 to form a protective area, the protective structure 1 may include an airbag 11. The airbag 11 may surround the periphery of the window and be arranged in a fan-shaped fold. The airbag 11 is configured to expand after inflation to form a protective area covering the window. The airbag 11 may be composed of multiple layers of fabric and can expand rapidly after inflation to partially cover the window, thereby improving the safety of the vehicle.
[0033] It can be understood that the protection structure 1 is configured as an airbag 11 for schematic purposes. In other embodiments, the protection structure 1 can also be a curtain-like fabric. The curtain-like fabric is elastic. When the cable 21 pulls the curtain-like fabric to unfold, the curtain-like fabric can also partially cover the window to form a protection area, so as to intercept and protect people in the car, and at the same time intercept foreign objects outside the cabin to reduce injuries to passengers.
[0034] In order to facilitate the connection of the airbag 11 with the window and the cable 21 respectively, in some feasible embodiments, the inner wall of the airbag 11 is formed with a first connection portion 111 extending toward the window and the outer wall of the airbag 11 is formed with a second connection portion 112 extending away from the window, the first connection portion 111 is fixedly connected to the cable 21, and the second connection portion 112 is used to be fixedly connected to the outer peripheral wall of the window, the first connection portion 111 and the second connection portion 112 can both be a single layer of fabric, and the first connection portion 111 can extend along the edge of the inner wall of the airbag 11 to facilitate the fixed connection of the first connection portion 111 with the cable 21, and the second connection portion 112 can extend along the edge of the outer wall of the airbag 11 to facilitate the fixed connection of the second connection portion 112 with the outer peripheral wall of the window.
[0035] Furthermore, in order to fix the second connecting portion 112 and the window, in some feasible embodiments, the protective structure 1 also includes a fastener, which may be a fastening screw. The second connecting portion 112 is provided with a plurality of spaced-apart mounting portions 113, and the window is provided with connecting holes corresponding one to one with the mounting portions 113. The mounting portions 113 may be an arc-shaped protrusion extending outward, and the connecting hole may be a through hole provided at the arc-shaped protrusion. The connecting hole may be a threaded hole, so that the fastener passes through the mounting portion 113 and is fixedly connected to the connecting hole.
[0036] Of course, the structure in which the second connection portion 112 is fixedly connected to the periphery of the window by fasteners passing through the mounting portion 113 is schematic. In other embodiments, the second connection portion 112 may also be fixed to the periphery of the window by gluing.
[0037] In order to facilitate the positioning of the folded airbag 11, in some practicable embodiments, the protective structure 1 further includes a drawstring 114, which may be a fabric, and may be in multiple numbers and arranged at intervals along the extension direction of the airbag 11. The drawstring 114 may be in the shape of a long strip, and the drawstring 114 extends along the width direction of the airbag 11. The width direction of the airbag 11 may refer to Figure 1 In the middle, it is perpendicular to the extension direction of the airbag 11, and the two ends of the drawstring 114 are fixedly connected to the first connecting part 111 and the second connecting part 112 respectively, so that the folded airbag 11 can be limited by the setting of the drawstring 114 to avoid excessive dispersion of the folded airbag 11, so that the inflated airbag 11 can be unfolded along the set space.
[0038] In order to facilitate the driving member 22 to pull the cable 21 to retract, in some feasible embodiments, the driving member 22 includes a gas generator 221 and a reel 222. The gas generator 221 is connected to the air inlet of the airbag 11. The gas generator 221 is used to generate gas and inflate the airbag 11. In this way, the airbag 11 can be inflated through the setting of the gas generator 221, so that the airbag 11 can be quickly deployed. The reel 222 is fixedly connected to the cable 21. The reel 222 is configured to tighten the cable 21 to guide the airbag 11 to deploy and cover the window, so that after the airbag 11 is deployed, a protective area covering the window is formed to protect the occupants from direct collision with the window glass and to prevent the occupants from being thrown out. At the same time, it can also prevent foreign objects from entering the car through the window and hitting the occupants. The protective area formed by the deployment of the airbag 11 can protect the occupants, thereby improving safety.
[0039] It can be understood that the gas generator 221 and the retractor 222 can be separately arranged or integrated with the gas generator 221 and the retractor 222, wherein the gas generator 221 is a conventional device in the airbag. For example, when the gas generator 221 and the retractor 222 are integrated, the retractor 222 can include an air cavity 223 and a reel 224, the air cavity 223 is arranged in the shell of the retractor 222, the air cavity 223 communicates with the gas generator 221 and the airbag 11, the first end of the reel 224 is fixedly connected to the cable 21, the second end of the reel 224 extends into the air cavity 223 and is configured to be able to As the gas passes through the air cavity 223, the reel 224 can be blown to rotate synchronously to tighten the cable 21. In this way, the gas generator 221 and the reel 222 can be integrated together. The gas produced by the gas generator 221 can not only inflate the airbag 11, but also drive the reel 224 in the reel 222 to tighten the cable 21. Therefore, when the airbag 11 is inflated and deployed, the reel 224 can simultaneously tighten the cable 21 to form a protective area covering the window, protecting the occupants from direct collision with the window glass and preventing the occupants from being thrown out. At the same time, it can also prevent foreign objects from entering the car through the window and hitting the occupants, thereby improving safety.
[0040] In some feasible embodiments, in order to facilitate the gas to drive the reel 224 to rotate and tighten the cable 21, the second end of the reel 224 is constructed as a fan blade structure, and the second end of the reel 224 extends into the air cavity 223 and is rotatably connected to the bottom wall of the air cavity 223. After the gas generator 221 generates gas that enters the air cavity 223, it blows the fan blade structure at the first end of the reel 224, thereby driving the reel 224 to rotate, so as to tighten the cable 21 connected to the second end of the reel 224, thereby inflating the airbag 11 and covering the window to form a protective area, protecting the occupants from direct collision with the window glass and preventing the occupants from being thrown out, thereby improving safety.
[0041] In order to facilitate the combing of the cable 21, in some feasible embodiments, the reel 222 also includes a wire bite 225, which is arranged on at least one side of the reel 224. The wire bite 225 is used to comb the cable 21. For example, two cable installation grooves are provided on the reel 224, and the two cables 21 are respectively wound according to the set installation grooves. A wire bite 225 is provided on each cable 21 and on both sides of the reel 224. The wire bite 225 can be fixed in the shell of the reel 222 and a through hole is provided in the wire bite 225 to guide the cable 21 to pass through. Therefore, through the setting of the wire bite 225, the guide cable 21 can be combed and tightened along the set trajectory to avoid mutual interference between the cables 21. It can be understood that the wire biteer 225 is arranged on the side of the reel 224 close to the airbag 11, so that the rope 21 cooperating with the airbag 11 can be guided and combed, and mutual interference can be avoided during the tensioning of the rope 21, so that the airbag 11 can be quickly unfolded after inflation and cover the window to form a protective area as the rope 21 is tightened.
[0042] In some practicable embodiments, in order to facilitate the cooperation between the cable 21 and the airbag 11, the occupant protection device further includes a wire take-up device 3, which is arranged on the cable 21 and close to the air inlet of the airbag 11. The wire take-up device 3 is used to provide tension to the cable 21 arranged at the periphery of the window, so that the folded airbag 11 can be arranged around the periphery of the window to avoid the airbag 11 being torn due to excessive tension or the airbag 11 being loose due to insufficient tension, which is not conducive to subsequent inflation and deployment; in addition, the occupant protection device further includes a wire block 4, a wire guide block 4, and a wire guide block 4. The wire block 4 is arranged on the side of the window close to the driving structure 2. The wire block 4 is constructed in an arc shape. Since the window is rectangular as a whole, the cable 21 has a corresponding corner when it is arranged, especially the cable 21 is introduced into the corner of the airbag 11 by the reel 222, and it is easy to get entangled during the process of tightening the cable 21. In this way, through the setting of the wire block 4, the movement trajectory of the cable 21 at the turning corner can be guided, so that the cable 21 can be tightened to make the airbag 11 smoothly deploy and cover the window to form a protection area, thereby improving the safety of the occupants.
[0043] In addition, in some practicable embodiments, in order to make the deployed protection area have a certain sealing property, the occupant protection device further includes a sealing ring 5, which avoids the cable 21 and is fixedly arranged on the second connection part 112. The sealing ring 5 may be a rubber pad, and the screw passes through the second connection part 112 and the sealing ring 5 and is fixedly connected to the outer edge of the window. Through the arrangement of the sealing ring 5, when the cable 21 pulls the airbag 11 to deploy toward the center of the window, the protection area is formed, and the second connection part 112 of the airbag 11 does not fall off and forms a seal with the window, thereby preventing external moisture from entering the vehicle, especially after the vehicle has waded through water, and the sealing property can provide a certain amount of time for passengers to escape.
[0044] The second aspect of the utility model provides a vehicle, including the above-mentioned occupant protection device. The cable 21 of the driving structure 2 is fixedly connected to the protection structure 1, and the driving member 22 retracts the cable 21 to make the protection structure 1 unfold, forming a protection area that at least partially covers the window, so that when the vehicle collides or foreign objects fly into the window from the outside, the setting of the protection structure 1 can not only timely protect the occupants from directly colliding with the glass of the window and preventing the occupants from being thrown out, but also prevent foreign objects from passing through the window into the vehicle and hitting the occupants, so that the protection area formed by the unfolding of the protection structure 1 can protect the occupants, thereby improving safety.
[0045] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
[0046] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
[0047] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
