[0047] To make the purpose, technical solution, and advantages of this application clearer, the following will be described in conjunction with the appendix. Figure 1-8 This application will be described in further detail. It is obvious that the described embodiments are merely some, not all, of the embodiments described herein. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0048] It should be understood that although the terms first, second, third, etc., may be used in the embodiments of this application, these descriptions should not be limited to these terms. These terms are only used to distinguish the descriptions. For example, first may also be referred to as second without departing from the scope of the embodiments of this application, and similarly, second may also be referred to as first.

[0049] In some specific embodiments, this application provides a window-breaking structure, including: a mounting housing 1; the mounting housing 1 has a window-breaking hole 2 on the side near the glass for the movement of a pin assembly 3; wherein the pin assembly 3 is disposed inside the mounting housing 1; the mounting housing 1 also has a pin limiting assembly 4 for restricting the movement of the pin assembly 3; the pin assembly 3 includes: a pin body 31 disposed inside the mounting housing 1; the front end of the pin body 31 has a small-diameter pin rod 32 that can pass through the window-breaking hole 2; the free end of the small-diameter pin rod 32 has a sharp part 33 for piercing the glass; one side of the pin body 31 has a limiting hole 34 that engages with the pin limiting assembly 4; a pressure spring 5 is disposed between the rear end of the pin body 31 and the mounting housing 1.

[0050] It is understood that by installing the ejector pin assembly 3 inside the housing 1, this application can quickly break the car window in an emergency, such as when the vehicle falls into water, to facilitate the escape of occupants and increase the escape rate of occupants.

[0051] In practical applications, the window-breaking structure used in this application can be applied to a position inside the vehicle near the window glass, such as the door glass, the windshield, or the corresponding position of the rear windshield. In this embodiment, the window-breaking structure is arranged on the door sheet metal on the driver's side as an example for illustration.

[0052] Specifically, the pin limiting assembly 4 includes: a linear servo motor 41 fixed to the inner wall of the mounting housing 1; the output shaft end of the linear servo motor 41 is provided with a locking part 42 that mates with the limiting hole 34; wherein, the locking part 42 is a sheet-like structure, and correspondingly, the limiting hole 34 is a square hole; it can be understood that by the locking part 42 arranged at the end of the output shaft cooperating with the limiting hole 34, the pressure spring 5 is limited and fixed; since the pressure spring 5 has a large restoring force, the advantage of the sheet-like structure design is that by increasing the contact area between the locking part 42 and the limiting hole 34, the locking part 42 is prevented from bending locally over time, which would cause jamming when the locking part 42 separates from the limiting hole 34, affecting the function.

[0053] Optionally, the window-breaking structure further includes a connecting structure 6; the connecting structure 6 includes: a shell reinforcing plate 61 fixedly connected to the body sheet metal; the shell reinforcing plate 61 has a fixing hole 62 in the middle for arranging the mounting shell 1; the upper and lower sides of the shell reinforcing plate 61 are connected to the mounting shell 1 through L-shaped brackets 63; the first wall of each bracket 63 is welded and fixed to the mounting shell 1; the second wall of the bracket 63 is connected and fixed to the shell reinforcing plate 61 by bolts; wherein, the first wall and the second wall are vertically connected.

[0054] It is understood that the housing reinforcement plate 61 can fix the housing 1 while also bearing the rebound force generated by the pressure spring 5, thereby ensuring the stability of the window breaking structure connection.

[0055] Specifically, this application, through its window-breaking structure, can quickly respond to the control commands of the vehicle's central control unit in emergency situations, such as when the vehicle falls into water or a fire occurs, to rapidly shatter the window, shorten rescue time, and increase the chances of survival for the people inside the vehicle.

[0056] In one specific embodiment, the application also includes a manual switch, wherein the manual switch may be arranged inside the vehicle and is electrically connected to the linear servo motor 41 via a wiring harness for turning on the linear servo motor 41.

[0057] Optionally, the left and right sides of the housing reinforcement plate 61 are provided with arc-shaped reinforcement portions 64; the ends of the arc-shaped reinforcement portions 64 extend outward and are provided with square fixing plates 65 that are fixedly connected to the body sheet metal. It can be understood that through the structural strength design of the housing reinforcement plate 61, the connection stability of the mounting housing 1 is ensured, while the size of the arc-shaped reinforcement portion 64 can be adapted according to the installation position of the mounting housing 1. That is, through the height difference between the two ends of the arc-shaped reinforcement portion 64, the distance between the sharp part 33 and the glass is ensured, which ensures that the sharp part 33 can break the glass during movement, while avoiding the sharp part from generating excessive piercing force and penetrating the body sheet metal, causing secondary injury to the occupants.

[0058] On the other hand, this application provides an escape system for a vehicle in the event of falling into water, including the aforementioned window-breaking structure; in this embodiment, the window-breaking structure is arranged on the driver's side door assembly 500 of the vehicle as an example.

[0059] The escape system also includes: an inflation device 7 fixed inside the lower crossbeam 100 of the front windshield, an escape airbag 8 connected to the inflation device 7, and an escape rope 9 connected to the escape airbag 8; wherein, one end of the escape rope 9 is fixedly connected to the lower crossbeam 100 of the front windshield through a connecting pin 74.

[0060] The inflation device 7 is fixed to the lower crossbeam 100 of the front windshield via a U-shaped bracket 10; one end of the escape airbag 8 is connected to the inflation device 7, and the other end is in contact with the water tank cover 200; the water tank cover 200 has a cover 300 corresponding to the part of the escape airbag 8; the cover 300 is pasted or snapped onto the water tank cover 200.

[0061] Specifically, when the vehicle falls into the water, the glass is broken through the window breaking structure, and the escape airbag 8 is inflated by the inflation device 7 to assist the occupants in escaping quickly. The escape airbag 8 is located inside the water tank cover 200; the external space of the water tank cover 200 is the atmosphere. It can be understood that during the inflation process, the escape airbag 8 breaks through the cover 300 on the water tank cover 200 and enters the external space of the vehicle, thereby assisting the occupants in escaping.

[0062] Specifically, one end of the escape rope 9 is fixed to a connecting pin 74, and the connecting pin 74 is connected to the lower crossbeam 100 of the front windshield; the escape rope 9 includes a first rope body 91 and a second rope body 92; one end of the first rope body 91 is fixedly connected to the escape airbag 8, and the other end is connected to the first rope body 91 through a buckle structure 93; the other end of the second rope body 92 is fixedly connected to the connecting pin 74; a connecting handle is also provided on the part of the first rope body 91 near the buckle structure 93.

[0063] Optionally, the outside of the escape airbag 8 is also provided with a conspicuous device; the conspicuous device includes: a positioning buoy 400 connected to the escape airbag 8; the surface of the positioning buoy 400 is uniformly arranged with fluorescent protrusions.

[0064] Understandably, the location of a person who has fallen into the water can be quickly located and found through the positioning buoy 400 and the fluorescent protrusions, which facilitates rescue operations.

[0065] Optionally, the inflation device 7 includes: an inflation pump 71, an inflation tube 72, and an airbag locking structure 73; the inflation tube 72 is disposed at the front end of the inflation pump 71, and the front end of the inflation tube is connected to the escape airbag 8 through the airbag locking structure 73; wherein, the airbag locking structure 73 is used to close the air passage connecting the escape airbag 8 and the inflation pump 71; the front end of the escape airbag 8 is glued and fixed to the inflation tube.

[0066] Specifically, the air pump 71 is electrically connected to the manual switch and the vehicle central control unit.

[0067] The airbag locking structure 73 includes: an elastic clamping sleeve 730 disposed on the outer side of the front end of the escape airbag 8, and an airbag guide part 731 disposed on the inner side of the escape airbag 8 and cooperating with the elastic clamping sleeve 730; wherein, the airbag guide part 731 is generally funnel-shaped, used for the direction of inflation of the escape airbag 8 and for cooperating with the elastic clamping sleeve 730 to seal the airway entering the escape airbag 8; the front end of the escape airbag 8 is fixed to the outer side of the airbag guide part 731 by the elastic clamping sleeve; one end of the airbag guide part 731 passes through the airbag locking hole in the middle of the elastic clamping sleeve 730 and is inserted into the inflation tube 72.

[0068] It is understood that the elastic clamping sleeve 730 is made of elastic material and is used to clamp the front end of the escape airbag 8; wherein the contact part between the front end of the escape airbag 8 and the inflation tube 72 is connected by adhesive.

[0069] In use, the air pump 71 introduces air into the escape airbag 8 through the inflation tube 72. The horn-shaped airbag guide part 731 gradually moves away from the inflation tube 72 under the action of high-pressure air until it separates from the elastic clamping sleeve 730. At this time, the elastic clamping sleeve 730 clamps the front end of the escape airbag 8 under its own elastic force, preventing the escape airbag 8 from continuing to take in air. Then, the front end of the escape airbag 8 continues to inflate under the action of high-pressure gas until it overcomes the adhesive force between the escape airbag 8 and the inflation tube 72, thereby completing the separation from the inflation tube 72.

[0070] For ease of use by occupants, the outer side of the escape airbag 8 is fixed to the lower crossbeam 100 of the windshield via a connecting pin 74. The purpose of this design is to make it easy for occupants to grab the escape airbag 8 when the vehicle falls into water. When occupants need to separate the escape airbag 8 from the vehicle, they only need to grab the connecting handle and manually press the buckle structure 93.

[0071] Optionally, the escape system further includes: a water level detection device, electrically connected to the vehicle's central control unit, for detecting water level information when the vehicle falls into water; a water pressure detection device, electrically connected to the vehicle's central control unit, for detecting water pressure information when the vehicle falls into water; and an alarm module, electrically connected to the vehicle's central control unit, configured to send alarm information in response to water pressure or water level information sent by the central control unit.

[0072] It is understood that the water level and water pressure detection devices can detect the water level and water pressure information when the vehicle falls into the water. When the alarm value is triggered, the vehicle controller sends a control command based on the water level and water pressure information. The linear servo motor 41 and the air pump 71 are turned on according to the control command. When the vehicle controller cannot work, the user can manually press the manual switch to start the linear servo motor 41 and the air pump 71.

[0073] It is understandable that this application, through its escape device, can respond quickly in emergency situations, such as when a vehicle falls into water, by breaking the car window glass and activating the escape airbag 8, making full use of the golden escape time to help the escapee escape, thereby increasing the escape rate.

[0074] On the other hand, this application provides a vehicle including the aforementioned escape system.
