Description

Technical Field

[0001] The present invention relates to the technical field of automotive accessories, and particularly to an adjustable window-breaking component and a sunshade curtain having the adjustable window-breaking component. Background Art

[0002] As the mainstream panoramic sunroof design, the automotive sliding sunroof usually consists of two rectangular glasses and is slidably opened through the roof rail system. Although the original factory sunroof glass generally has an anti-ultraviolet coating (ultraviolet blocking rate ≥ 90%), it still cannot completely resist the infrared thermal radiation in the high-temperature environment in summer, and it is easy to cause overexposure of the light inside the vehicle when directly irradiated by strong light, affecting the rest of the passengers. Therefore, users often need to install a sunshade curtain for the sunroof by themselves to optimize the driving experience.

[0003] The existing sunshade curtains for sunroofs have the following technical bottlenecks in practical applications:

[0004] The fixed installation mode of the traditional roller sunshade curtain causes it to only statically cover the initial position of the sunroof. When the sunroof glass slides open, the sunshade curtain cannot move and adjust the shielding range accordingly, resulting in continuous light transmission in the uncovered area.

[0005] Conventional sunshade curtains only provide the function of light blocking and lack the active safety design for emergency window breaking. When a vehicle collision or water accident occurs, passengers need to find additional window-breaking tools. And a large number of sharp glass fragments will be generated instantaneously when the traditional sunroof glass breaks. The existing sunshade curtains can neither assist in quickly breaking the window nor effectively block the broken glass from invading the vehicle interior, presenting a potential risk of secondary injury.

[0006] The traditional sunroof escape plan relies on an electric control system. When the vehicle loses power or the system fails, passengers need to break the window by physical hitting. However, the laminated structure and high-strength characteristics of the sunroof glass result in a long time-consuming window-breaking process, and the remaining glass cross-section after breaking is sharp, which is prone to cause scratching risks during the escape process. Summary of the Invention

[0007] In order to overcome the above technical problems, the purpose of the present invention is to provide an adjustable window-breaking component and a sunshade curtain having the adjustable window-breaking component, so as to solve the problems in the above background art that the existing sunshade curtains for sunroofs cannot follow the adjustment of the shielding range when the sunroof is opened due to the traditional roller fixed installation, lack the active safety design for emergency window breaking, and the escape plan relying on electric control is prone to cause secondary injuries due to the long window-breaking time and the remaining sharp glass fragments when the vehicle loses power or the system fails.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an adjustable window-breaking assembly, comprising a skylight top frame, a fixed skylight component and a movable dynamic skylight component, wherein the assembly also includes: a controllable sunshade curtain assembly, installed inside the skylight top frame, for blocking the light transmitted by the fixed skylight component and the dynamic skylight component, and having a driving mechanism with an adjustable shading range; a linkage adjustment assembly, for controlling the linkage or independent operation of the opening and closing actions of the inner sunshade curtain assembly and the dynamic skylight component; a window-breaking assembly, integrated into the operating component of the controllable sunshade curtain assembly, for smashing the dynamic skylight component in an emergency and forming a broken glass protection structure.

[0009] Preferably, the controllable sunshade curtain assembly includes: a front movable frame and a rear fixed frame that are rotatably connected, wherein the front movable frame cooperates with the limit platform through a groove and a magnetic structure to constrain its unidirectional rotational freedom; an inner sunshade curtain assembly driven by a coil spring, wherein the free end of the curtain body is provided with an end slat, and the end slat realizes displacement control through friction contact with the transmission belt.

[0010] Preferably, the driving mechanism includes: a rigid connection structure between the worm and the adjusting knob; the front shaft is rotationally driven by the engagement of the worm gear, and forms a friction transmission system with the transmission belt; the transmission belt realizes the adjustment of the sunshade's expansion amount and self-locking position through the friction contact of the end slats.

[0011] Preferably, the linkage adjustment component includes: a liftable vertical rod, which slides with the front moving frame through a follower plate connected by a spring; a fixed plate arranged at the bottom of the moving skylight component, which establishes a synchronous displacement relationship between the inner sunshade curtain assembly and the moving skylight component when the vertical rod is coupled with the fixed plate.

[0012] Preferably, the vertical rod is provided with: a through-hole guide structure penetrating the end slats; a sliding limit portion cooperating with the long slot of the front movable frame; and an elastic plug-in mechanism which realizes automatic engagement with the fixed plate through spring reset.

[0013] Preferably, the window breaking assembly includes: a push rod hidden in the adjusting button, with a window breaker fixed at the end thereof; an anti-accidental touch protection mechanism, including a limit pin and a silicone sleeve covering the adjusting button; and a window breaker release channel, which passes through the worm and extends to the contact surface of the moving skylight component.

[0014] Preferably, the push rod is provided with: a linear motion guide structure cooperating with the adjusting button slide groove; an energy storage impact mechanism composed of a return spring, which allows continuous triggering of the window breaking operation; and a limit pin insert-type locking device for fixing the stroke in non-emergency conditions.

[0015] Preferably, the transmission belt is driven by friction between the front shaft and the driven wheel, converting the rotational motion of the worm gear reduction mechanism into linear displacement of the end slats, and utilizing the self-locking characteristics of the worm gear to suppress accidental retraction of the inner sunshade assembly.

[0016] Preferably, after the window-breaking component is triggered, the front moving frame can rotate clockwise along the limit table board, pushing the broken moving sunroof component to displace outward. At the same time, the inner sunshade curtain component unfolds to cover the sharp glass section at the edge of the sunroof opening.

[0017] A sunshade curtain adopts the adjustable and window-breaking integrated component according to any one of the above-mentioned claims 1-9.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. By integrating the sunshade curtain adjusting mechanism and the window-breaking component into the sunroof system, the integrated design of the dual functions of sunshading and window-breaking is realized, effectively simplifying the in-vehicle structure layout, reducing the extra occupied space, and at the same time improving the operation convenience;

[0020] 2. Adopting the switchable linkage adjusting component enables the sunshade curtain to be adjusted synchronously with the opening and closing of the sunroof and can also operate independently, meeting the diverse needs of users for light shading and enhancing the use flexibility;

[0021] 3. When breaking the window emergently, the sunshade curtain component follows and covers the broken glass area, forming a flexible barrier to wrap the sharp glass edge, significantly reducing the risk of glass fragments splashing or scratching people, and providing multiple safety guarantees for the occupants;

[0022] 4. The hidden window-breaking component realizes quick window-breaking through a simple triggering design. The reset spring supports multiple impact operations, ensuring the efficient opening of the escape passage in case of emergency. At the same time, the anti-misoperation structure takes into account the safety of daily use. Description of the Drawings

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] An embodiment provided by the present invention: An adjustable window-breaking assembly and a sunshade curtain having the adjustable window-breaking assembly, including a skylight top frame 11, a fixed skylight member 12, and a movable skylight member 13. The movable skylight member 13 is used to open or close on the skylight top frame 11 through a control mechanism. Among them, it further includes:

[0034] Refer to Figures 1 - 4 , a controllable sunshade curtain assembly 20, and the controllable sunshade curtain assembly 20 is used to block the sunlight transmitted through the fixed skylight member 12 and the movable skylight member 13;

[0035] The controllable sunshade curtain assembly 20 is installed inside the skylight top frame 11 and at the bottom of the fixed skylight member 12 and the movable skylight member 13. The controllable sunshade curtain assembly 20 includes a front movable frame 211 and a rear fixed frame 212. The front movable frame 211 and the rear fixed frame 212 are rotatably connected. Refer to Figure 6 As shown, one side of the front movable frame 211 away from the rear fixed frame 212 contacts a limit table board 213 through a groove, and the front movable frame 211 and the limit table board 213 are also in magnetic contact. The limit table board 213 is fixedly connected to the skylight top frame 11, and the rear fixed frame 212 is fixedly connected to the skylight top frame 11. With this design, since the limit table board 213 limits the front movable frame 211 through the groove, the front movable frame 211 can only be adjusted clockwise around the position where it is rotatably connected to the rear fixed frame 212.

[0036] Refer to Figures 4 - 5, a rear fixed frame 212 and a front movable frame 211 are provided with an internal sunshade curtain assembly 22 at the top. The internal sunshade curtain assembly 22 includes a wound sunshade curtain member and a reel. The two ends of the reel are rotatably connected to the rear fixed frame 212. A torsion spring is installed inside the reel for winding the sunshade curtain member. The torsion spring cannot directly pull the end strip 23 to force displacement, but is only designed to assist in winding the sunshade curtain member of the internal sunshade curtain assembly 22. One end of the sunshade curtain member is wound on the reel, and the other end of the sunshade curtain member is fixedly connected to the end strip 23.

[0037] Reference Figure 5 , a worm 25 is provided inside the front movable frame 211. The two ends of the worm 25 are rotatably connected to the front movable frame 211. One end of the worm 25 is fixedly connected to an adjustment knob 24. A front shaft rod 26 is arranged on the side of the worm 25. A worm gear is fixedly connected to the front shaft rod 26, and the front shaft rod 26 is meshed with the worm 25 through the worm gear. The two ends of the front shaft rod 26 are rotatably connected to the front movable frame 211. The front shaft rod 26 is connected with a transmission belt 27. The side of the transmission belt 27 away from the front shaft rod 26 is connected with a runner, and this runner is rotatably connected to the rear fixed frame 212. The transmission belt 27 is in frictional contact with the end strip 23 through a groove.

[0038] During use, when the adjustment knob 24 is rotated, the adjustment knob 24 drives the worm 25 and then drives the front shaft rod 26 to rotate. The rotation of the front shaft rod 26 drives the end strip 23 to move left or right on the front movable frame 211 and the rear fixed frame 212 through the transmission belt 27, so as to adjust the covering position of the internal sunshade curtain assembly 22 to meet the needs of users. And because the front shaft rod 26 cannot drive the worm 25 to have a self-locking function, the sunshade curtain member in the internal sunshade curtain assembly 22 will not be automatically retracted by the torsion spring in the reel. The torsion spring in the reel is mainly used to assist in winding the sunshade curtain member. The transmission belt 27 is connected to the front shaft rod 26 and the runner through friction. When the worm 25 drives the front shaft rod 26, the transmission belt 27 will be driven to move through friction, and then the runner will be driven to rotate through the transmission belt 27, so as to drive the displacement of the end strip 23. When the end strip 23 is moved, because the end strip 23 is in frictional contact with the transmission belt 27, the transmission belt 27 will not move due to the self-locking effect of the end strip 23.

[0039] Reference Figures 6 - 8As shown in the figure, an adjusting component 28 is arranged inside the front moving frame 211. The adjusting component 28 is used to control whether the sunshade component 22 of the inner sunshade curtain moves along with the moving skylight component 13. The adjusting component 28 includes a vertical rod 281. The vertical rod 281 is in sliding contact with the end head plate strip 23 through a through hole. The vertical rod 281 can move up and down in the end head plate strip 23 through the through hole. The vertical rod 281 is connected with a follower plate 283 through a spring. The follower plate 283 is connected to the bottom of the front moving frame 211 through a chute. The vertical rod 281 is in sliding contact with the front moving frame 211 through a long slot. One end of the vertical rod 281 contacts a fixed disk 282 through a groove. The fixed disk 282 is fixedly connected to the bottom of the moving skylight component 13;

[0040] During use, when the skylight needs to be opened, the moving skylight component 13 is first lifted by the control mechanism, then moves towards the fixed skylight component 12, and finally the moving skylight component 13 and the fixed skylight component 12 are close to overlapping to complete the opening of the skylight. Among them, the moving skylight component 13 and the fixed skylight component 12 will not completely overlap, and a part of the moving skylight component 13 will extend beyond the fixed skylight component 12 on the left side;

[0041] Reference Figures 5 - 6 , since one end of the vertical rod 281 contacts the fixed disk 282 through a groove, the fixed disk 282 will move along with the movement of the moving skylight component 13. When the moving skylight component 13 drives the end head plate strip 23 to move through the adjusting component 28, because the worm gear on the front axle rod 26 is self-locking and the transmission belt 27 is in frictional contact with the front axle rod 26, the transmission belt 27 is also immovable. However, since the end head plate strip 23 is in frictional contact with the transmission belt 27, it will be driven by the adjusting component 28, and then drive the inner sunshade curtain component 22 to move. The specific process of the moving skylight component 13 driving the adjusting component 28 to move is that one end of the vertical rod 281 contacts the fixed disk 282 through a groove. When the moving skylight component 13 rises, the spring between the vertical rod 281 and the follower plate 283 releases the tension, so that the vertical rod 281 also rises and continuously maintains groove contact with the fixed disk 282. Along with the rightward movement of the moving skylight component 13, it drives the adjusting component 28 to move. Among them, the vertical rod 281 will slide in the long slot of the front moving frame 211, and the follower plate 283 is in sliding contact with the vertical rod 281 through a through hole;

[0042] When the sunshade curtain component does not need to move along with the moving skylight component 13, by pulling down the vertical rod 281, the spring between the vertical rod 281 and the follower plate 283 will stretch with stored energy, and one end of the vertical rod 281 will disengage from the groove contact with the fixed disk 282. As a result, the moving skylight component 13 will not drive the adjusting component 28 and thus cannot drive the end head plate strip 23 to move. This design enables the sunshade curtain component to have the effect of selectively following or not following the opening and closing movement of the moving skylight component 13.

[0043] Reference Figure 5, the window-breaking component 30 is used to break the movable sunroof part 13. In the event that the vehicle falls into water or an accident occurs, the vehicle loses power or the control system fails. After directly removing the silicone sleeve 33 and the limit pin 32, the push rod 31 is pushed upward. The push rod 31 drives the window breaker 34 to move upward. The end of the window breaker 34 will directly contact the movable sunroof part 13. The window breaker 34 is a product that can be directly purchased in the prior art, and its specific working principle will not be elaborated too much in this text. The working end of the window breaker 34 will break the movable sunroof part 13 to generate cracks. Then, by pushing the front movable frame 211, the front movable frame 211 will rotate clockwise. The front movable frame 211 and the inner sunshade curtain assembly 22 will move together, and the movable sunroof part 13 can be pushed outward to break the vehicle body. Moreover, since the inner sunshade curtain assembly 22 and the front movable frame 211 cover a large part of the movable sunroof part 13, they can wrap the broken glass, provide protection for the people in the vehicle, reduce the amount of glass invading the interior, and when people climb out from the original position of the movable sunroof part 13, due to the sunshade curtain part in the inner sunshade curtain assembly 22 covering the edge of the glass, the damage of the broken glass to people can be reduced.

[0044] The window-breaking component 30 includes a push rod 31. The push rod 31 is fixedly connected to a window breaker 34. The push rod 31 is in sliding contact with an adjustment knob 24 through a chute. The adjustment knob 24 is designed with a limit groove corresponding to the push rod 31 to prevent the push rod 31 from slipping out of the adjustment knob 24. There is also a spring in the chute of the adjustment knob 24 corresponding to the push rod 31. This spring is sleeved on the window breaker 34 and the push rod 31. During the process of pushing the push rod 31 upward, the spring stores energy and contracts. Releasing the push on the push rod 31 will release the stored energy and reset the push rod 31. This design allows the operator to use the push rod 31 and the window breaker 34 to break the movable sunroof part 13 multiple times to improve the breaking effect on the movable sunroof part 13. The adjustment knob 24 also includes a limit pin 32. The limit pin 32 passes through the push rod 31 and the adjustment knob 24 through a through hole to prevent the push rod 31 from displacing under non-emergency conditions. The adjustment knob 24 and the limit pin 32 are externally sleeved with a silicone sleeve 33. The silicone sleeve 33 is made of a flexible material. Its main function is to prevent the limit pin 32 from slipping out of the adjustment knob 24 and to facilitate the user to grasp the adjustment knob 24 for rotation control, improving comfort.

[0045] Reference Figure 5, in the broken window component 30, the window breaker 34 contacts the worm 25 and the adjustment knob 24 through the chute. One end of the worm 25 is also provided with an opening to facilitate the window breaker 34 to extend from the worm 25 to strike and break the movable sunroof member 13. In this broken window component 30, structures such as the push rod 31 and the window breaker 34 are built into the adjustment knob 24 and the worm 25 of the controllable sunshade curtain component 20. The adjustment knob 24 in the controllable sunshade curtain component 20 is located at the position above the heads between the driver's and passenger's seats. The significance of designing it here is to facilitate the use by the driver and passenger, and the built-in push rod 31 also facilitates people to quickly use it in case of emergency, improving the use efficiency.

[0046] Working principle:

[0047] When it is necessary to block the sunlight passing through the movable sunroof member 13 and the fixed sunroof member 12 in the vehicle, by rotating the adjustment knob 24, the adjustment knob 24 can adjust the position of the inner sunshade curtain component 22 to achieve the purpose of blocking the movable sunroof member 13 and the fixed sunroof member 12. By choosing whether to insert one end of the vertical rod 281 in the adjustment component 28 into the fixed disk 282, when the vertical rod 281 is inserted into the fixed disk 282, the vehicle starts the movable sunroof member 13, and the movable sunroof member 13 will drive the sunshade curtain member to move together through the adjustment component 28. When the vertical rod 281 is not inserted into the fixed disk 282, the sunshade curtain member in the inner sunshade curtain component 22 can be made not to move with the movement of the movable sunroof member 13, achieving a selective control effect;

[0048] In case of emergency when it is necessary to break the movable sunroof member 13, by removing the silicone sleeve 33 and the limit pin 32 and pushing the push rod 31 upward, the window breaker 34 can break the movable sunroof member 13, and then push the front movable frame 211 to rotate clockwise ( Figure 4 and Figure 5 ), the movable sunroof member 13 can be pushed to be completely broken and opened, and the broken glass will be blocked by the front movable frame 211 and the sunshade curtain member in the inner sunshade curtain component 22, reducing the possible injury to the vehicle occupants when the movable sunroof member 13 breaks and the broken glass falls, and also being able to wrap the broken glass edge on one side of the movable sunroof member 13, reducing the injury to people when climbing out from the position of the movable sunroof member 13 and being scratched by the glass edge.

[0049] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
