Description

Technical Field

[0001] This invention relates to the field of vehicle engineering technology, specifically to an automatic window-breaking device for vehicles that have fallen into water. Background Technology

[0002] Vehicles, as a general term for man-made transportation tools, are machines that use power devices or external forces to move and transport. They help humans overcome geographical limitations, greatly shorten the distance between people and between people and things, and thus significantly improve the efficiency of movement and transportation.

[0003] Speeding, distracted driving, or fatigued driving on roads near water can cause vehicles to lose control and plunge into the water. Once in the water, water will quickly rush into the vehicle through the gaps in the doors and the air conditioning vents, causing short circuits in the vehicle's internal circuitry. Furthermore, as the vehicle sinks, the increased external water pressure can make it impossible to open the doors, endangering the lives of the people inside.

[0004] Currently, when a vehicle enters water, the rescue method often relies on the driver or passengers using a window breaker to break the glass and escape through the window. However, after the vehicle enters water, the occupants often cannot find and break the window in time, resulting in a delay in breaking the window. To solve this problem, existing technology involves adding a fixed bracket to the inside of the car door to install the window breaker in a specific position, making it easy for occupants to reach and break the window immediately. However, in actual use, after the vehicle enters water, the occupants may panic due to the impact, and breaking tempered glass requires a strong blow to the corner of the glass, making it difficult to break the window in time for escape, thus failing to meet the rapid escape needs of the occupants. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic window-breaking device for vehicles that have fallen into water, solving the problem of the inconvenience of breaking car windows in a timely manner after a vehicle has fallen into water.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an automatic window-breaking device for vehicles falling into water, comprising a car, wherein window-breaking mechanisms are provided on both the front and rear sides of the car interior, the window-breaking mechanisms being used to facilitate breaking the windows of the vehicle; a release mechanism is provided on the bottom of the car interior, the release mechanism being used to facilitate unfastening the seat belts of the occupants; and a floating mechanism is provided on the outside of the car, the floating mechanism being used to facilitate the vehicle floating on the water surface.

Vehicle seat belts are provided at the front and rear ends of the upper middle part of the inner side of the vehicle. A seat belt buckle is fixedly connected to one end of the vehicle seat belt.

[0008] Preferably, the floating mechanism includes a mounting box, and multiple mounting boxes are respectively fixedly connected to the front and rear walls and left and right sides of the vehicle. An air pump is fixedly connected to one end of the interior of the mounting box, and the output end of the air pump is connected to a delivery pipe. A push plate is slidably connected inside the hollow box, and an airbag is fixedly connected to one side of the push plate. One end of the delivery pipe passes through the push plate and communicates with the airbag. A connecting pipe is connected to one side of the outer wall of the delivery pipe. A fixing plate is fixedly connected to the rear side of the top of the interior of the mounting box. The top end of the connecting pipe communicates with the fixing plate. A piston plate is slidably connected to the inner side of the fixing plate. A support plate is fixedly connected to the outer side of the piston plate. The outer side of the support plate passes through the mounting box and is fixedly connected to the push plate.

[0009] Preferably, the pushing assembly includes a guide rod, which is fixedly connected to the top inner side of the hollow plate, and a spring is provided on the upper outer wall of the guide rod, with the bottom end of the guide rod penetrating the movable plate.

[0010] Preferably, the window-breaking mechanism further includes a guide rail, which is fixedly connected to the top inner side of the hollow box, and the inner side of the guide rail is slidably connected to the hollow plate.

[0011] Preferably, the tripping mechanism further includes mounting plates, two of which are fixedly connected to the bottom left and right sides of the fixing box, respectively. The top of the mounting plate is threaded with a bolt, and the bottom end of the bolt passes through the mounting plate and is threaded to the vehicle.

[0012] Preferably, the release mechanism further includes a fixing rod, which is fixedly connected to the inside right side of the fixing box, and the outside of the fixing rod is slidably connected to the moving plate.

[0013] Preferably, the floating mechanism further includes a one-way valve, which is disposed on the other side of the outer wall of the delivery pipe, and a sealing plate is fixedly connected to one side of the piston plate.

[0014] Preferably, the floating mechanism further includes a baffle plate, which is disposed inside one end of the mounting box.

[0015] Preferably, the window-breaking mechanism further includes buttons, two of which are fixedly connected to the front and rear ends of the lower middle part of the inner side of the vehicle, and the buttons are electrically connected to the motor, the electric telescopic rod and the air pump respectively.

[0016] This invention provides an automatic window-breaking device for vehicles that have fallen into water. It has the following beneficial effects: 1. This invention uses a motor to drive a threaded rod to rotate, which in turn pushes a hollow plate to move. When the hollow plate moves to the window, it is exactly at the end of the thread of the threaded rod. At this time, the rotation of the threaded rod will cause the hollow plate to rotate, and a spring will push a movable plate to extend out of the hollow plate. The movable plate will then drive the hammer to move and strike the window, quickly breaking the window and facilitating the escape of passengers.

[0017] 2. This invention uses an electric telescopic rod to move the mounting base. The mounting base, through a connecting rod, moves the moving plates on both sides towards the center simultaneously, thereby causing the locking block to disengage from the plug-in block and releasing the limiting effect on the plug-in block. At this time, pulling the vehicle's seat belt will cause the seat belt buckle and buckle socket to move simultaneously, automatically releasing the vehicle's seat belt from the occupant and preventing the occupant from being unable to unfasten the seat belt due to panic.

[0018] 3. In this invention, the air pump inflates the airbag through the delivery pipe and delivers the gas to the fixed plate through the connecting pipe, which pushes the piston plate to move. The piston plate pushes the push plate through the support plate to push the airbag out of the mounting box. The air pump continuously inflates the airbag, which causes the airbag to expand. Thus, the buoyancy of the airbag allows the car to float on the water surface and not sink to the bottom, improving the survival rate of people after the vehicle falls into the water.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figure 3 , Figure 4 and Figure 5 This invention provides an automatic window-breaking device for vehicles that have fallen into water, including a car 1. The car 1 has window-breaking mechanisms 2 on both the front and rear sides of its interior. The window-breaking mechanisms 2 are used to facilitate breaking the windows of the vehicle. The bottom of the car 1 has a release mechanism 3, which is used to facilitate unfastening the seat belts of the occupants. The car 1 has a floating mechanism 4 on its outer side, which is used to facilitate the vehicle floating on the water surface. The window-breaking mechanism 2 includes two hollow boxes 21, which are fixedly connected to the front and rear sides of the interior of the car 1, respectively. A motor 22 is fixedly connected to the left side of the hollow box 21. The output end of the motor 22 passes through the hollow box 21 and is fixedly connected to a threaded rod 23. The motor 22 drives the threaded rod 23 to rotate. A hollow plate 24 is threadedly connected to the outer side of the threaded rod 23. When the threaded rod 23 rotates, it drives the hollow plate 24 to move. When the hollow plate 24 moves to the threaded end, it drives the hollow plate 24 to rotate. A movable plate 25 is slidably connected to the inner side of the hollow plate 24. A hammer 26 is fixedly connected to the bottom of the movable plate 25 through the hollow plate 24. The hollow plate 24 can drive the hammer 26 to move through the movable plate 25. A window 27 is provided on the side, which facilitates the rotation of the hollow plate 24. A pushing component 28 is provided on the inner side of the hollow plate 24. The pushing component 28 includes a guide rod 281, which is fixedly connected to the top of the inner side of the hollow plate 24. A spring 282 is provided on the upper side of the outer wall of the guide rod 281. The spring 282 can push the movable plate 25 out of the hollow plate 24. The bottom end of the guide rod 281 passes through the movable plate 25. The window breaking mechanism 2 also includes buttons 210. Two buttons 210 are fixedly connected to the front and rear ends of the lower middle part of the inner side of the car 1, respectively. The buttons 210 are electrically connected to the motor 22, the electric telescopic rod 32 and the air pump 42, respectively. When the button 210 is pressed, the motor 22, the electric telescopic rod 32 and the air pump 42 will be started at the same time. Specifically, when the vehicle unfortunately falls into the water, after the occupant presses button 210, motor 22 will start and drive threaded rod 23 to rotate. Since hollow plate 24 is connected to threaded rod 23, the rotation of threaded rod 23 will drive hollow plate 24 to move. When hollow plate 24 moves to window 27, the position of hollow plate 24 just reaches the threaded end of threaded rod 23. At this time, the continued rotation of threaded rod 23 will no longer drive hollow plate 24 to move, but will drive hollow plate 24 to rotate around threaded rod 23. At the same time, spring 282 will push movable plate 25 to extend, and hollow plate 24 will drive movable plate 25 to rotate, thereby driving hammer 26 fixed at the end of movable plate 25 to move, thereby breaking the window glass and opening an escape route for the people inside the vehicle.

[0023] Reference Figure 3 , Figure 6 and Figure 7The tripping mechanism 3 includes a fixed box 31, which is fixedly connected to the inner bottom of the vehicle 1. An electric telescopic rod 32 is fixedly connected to the left side inside the fixed box 31. A mounting base 33 is fixedly connected to the output end of the electric telescopic rod 32. The electric telescopic rod 32 will pull the mounting base 33 to move. A connecting rod 34 is rotatably connected to the front and rear sides inside the mounting base 33. A moving plate 35 is rotatably connected to one end of the connecting rod 34. The mounting base 33 can pull the moving plate 35 to move through the connecting rod 34. A locking block 36 is fixedly connected to the top of the moving plate 35. A latching socket 38 is provided on the front and rear sides of the top of the fixed box 31. A plug-in block 37 is fixedly connected to the bottom of the latching socket 38. A through-hole is fixed to the outer side of the plug-in block 37. The fixed box 31 engages with the locking block 36. The moving plate 35 will drive the locking block 36 to move, thereby disengaging the locking block 36 from the plug-in block 37 and releasing the limiting effect on the plug-in block 37. The upper middle and rear ends of the inner side of the car 1 are equipped with vehicle seat belts 39. One end of the vehicle seat belt 39 is fixedly connected to a seat belt buckle 310. Pulling the vehicle seat belt 39 will drive the seat belt buckle 310 and buckle socket 38 to move synchronously. The release mechanism 3 also includes a fixed rod 311. The fixed rod 311 is fixedly connected to the inside right side of the fixed box 31. The outer side of the fixed rod 311 is slidably connected to the moving plate 35. The moving plate 35 can only slide on the outer side of the fixed rod 311, thereby guiding the movement of the moving plate 35. Specifically, when the occupant presses button 210, the electric telescopic rod 32 is activated. The electric telescopic rod 32 pulls the connected mounting base 33 to move to the left. Since the mounting base 33 is connected to the two movable plates 35 on both sides through the connecting rod 34, the movement of the mounting base 33 will pull the two movable plates 35 on both sides towards the middle through the connecting rod 34. The movable plates 35 will move along with the locking block 36, causing the locking block 36 to disengage from the plug-in block 37 and release the locking restriction on the plug-in block 37. At this time, the occupant only needs to pull the vehicle seat belt 39, and the entire seat belt buckle 310 can be pulled together with the originally fixed buckle socket 38, thereby freeing the occupant from the restraint of the vehicle seat belt 39.

[0024] Reference Figure 1 , Figure 8 and Figure 9The floating mechanism 4 includes mounting boxes 41, multiple mounting boxes 41 are fixedly connected to the front and rear walls and left and right sides of the vehicle 1 respectively. An air pump 42 is fixedly connected to one end of the mounting box 41. The output end of the air pump 42 is connected to a delivery pipe 43. A push plate 44 is slidably connected inside the hollow box 21. An airbag 45 is fixedly connected to one side of the push plate 44. One end of the delivery pipe 43 passes through the push plate 44 and is connected to the airbag 45. The air pump 42 can deliver gas to the airbag 45 through the delivery pipe 43. A connecting pipe 47 is connected to one side of the outer wall of the delivery pipe 43. A fixing plate 46 is fixedly connected to the rear top of the mounting box 41. Gas can be delivered to the fixing plate 46 through the connecting pipe 47. The top end is connected to the fixed plate 46. The piston plate 48 is slidably connected to the inner side of the fixed plate 46. When the air pressure in the fixed plate 46 increases, it will push the piston plate 48 to move. The outer side of the piston plate 48 is fixedly connected to the support plate 49. The outer side of the support plate 49 passes through the mounting box 41 and is fixedly connected to the push plate 44. The piston plate 48 can push the push plate 44 to move through the support plate 49. The floating mechanism 4 also includes a one-way valve 410. The one-way valve 410 is located on the other side of the outer wall of the delivery pipe 43. The one-way valve 410 can prevent gas leakage inside the airbag 45 when the air pump 42 stops working. A sealing plate 411 is fixedly connected to one side of the piston plate 48. The sealing plate 411 can improve the sealing performance of the piston plate 48. Specifically, when the vehicle falls into the water, pressing button 210 will simultaneously activate four air pumps 42. The air pumps 42 will start supplying gas to the airbag 45 through the delivery pipe 43 and send the gas into the interior of the fixing plate 46 through the connecting pipe 47. When the air pressure in the fixing plate 46 increases, it will push the piston plate 48 to move. The piston plate 48 will further drive the push plate 44 to move through the support plate 49, thereby pushing the entire airbag 45 out of the mounting box 41. At this time, the air pumps 42 are still inflating the airbag 45 to expand its volume. The buoyancy generated by the airbag 45 will allow the car 1 to float on the water surface and thus not sink directly.

[0025] Reference Figure 2 and Figure 4 The window breaking mechanism 2 also includes a guide rail 29, which is fixedly connected to the top inner side of the hollow box 21. The inner side of the guide rail 29 is slidably connected to the hollow plate 24, and the guide rail 29 provides movement guidance for the hollow plate 24. Specifically, the movement of the hollow plate 24 is guided by the guide rail 29, so that when the threaded rod 23 rotates, the hollow plate 24 can move accordingly.

[0026] Reference Figure 6 and Figure 9The release mechanism 3 also includes mounting plates 312. Two mounting plates 312 are fixedly connected to the bottom left and right sides of the fixed box 31 respectively. The top of the mounting plate 312 is threaded with a bolt 313. The bottom end of the bolt 313 passes through the mounting plate 312 and is threadedly connected to the car 1. The floating mechanism 4 also includes a baffle plate 412. The baffle plate 412 is set inside one end of the mounting box 41. Plastic buckles 413 are fixedly connected to the left and right ends of one side of the baffle plate 412. The front and rear sides of the mounting box 41 are provided with slots 414. The plastic buckles 413 engage with the slots 414. The baffle plate 412 can be fixed by the plastic buckles 413. Specifically, the mounting box 31 can be removed by unscrewing bolts 313, making it convenient for staff to inspect and maintain the mounting box 31. The baffle 412 is fixed by plastic clips 413, which provides protection for the mounting box 41 when the vehicle is in motion. When the airbag 45 is deployed, the plastic clips 413 will break under force, causing the baffle 412 to fall off.

[0027] Working principle: When the vehicle falls into the water, pressing button 210 starts the motor 22. The motor 22 drives the threaded rod 23 to rotate. When the threaded rod 23 rotates, it drives the hollow plate 24 to move. When the hollow plate 24 moves to the window 27 position, it is exactly at the end of the thread of the threaded rod 23. When the threaded rod 23 rotates, it will not continue to drive the hollow plate 24 to move, but will drive the hollow plate 24 to rotate. The spring 282 will push the movable plate 25 to extend. The hollow plate 24 drives the movable plate 25 to rotate, which in turn drives the hammer 26 at the end of the movable plate 25 to move, thereby knocking on the window and breaking the window quickly, making it easier for passengers to escape. Furthermore, after the occupant presses button 210, the electric telescopic rod 32 will start simultaneously. The electric telescopic rod 32 will pull the mounting base 33 to move to the left. Since the mounting base 33 is connected to the moving plate 35 through the connecting rod 34, the leftward movement of the mounting base 33 will pull the moving plates 35 on both sides to move to the middle at the same time through the connecting rod 34. The moving plate 35 will further drive the locking block 36 to disengage from the plug-in block 37, thereby releasing the limiting effect on the plug-in block 37. At this time, when the occupant needs to get out of trouble, he / she can pull the vehicle seat belt 39. The vehicle seat belt 39 will drive the seat belt buckle 310 and buckle socket 38 to move at the same time, which can automatically release the restraint of the vehicle seat belt 39 on the occupant. Finally, after the vehicle falls into the water, pressing button 210 will simultaneously start four air pumps 42. The air pumps 42 can inflate the airbags 45 through the delivery pipe 43, and the delivery pipe 43 can deliver the gas to the fixing plate 46 through the connecting pipe 47. When the air pressure in the fixing plate 46 increases, it will push the piston plate 48 to move. When the piston plate 48 moves, it can push the push plate 44 to move through the support plate 49, thereby pushing the airbag 45 out of the mounting box 41. At this time, the air pumps 42 continue to inflate the airbags 45, which will cause the airbags 45 to expand. Then, the buoyancy of the airbags 45 will allow the car 1 to float on the water surface and not sink to the bottom.
