[0002] With the booming development of the tourism industry, tourist buses with a large passenger capacity are one of the best choices for company team building or tourist group travel. Due to the large passenger capacity of tourist buses, the importance of their escape assistance devices for vehicles is even more self-evident. The common auxiliary escape devices are window-breaking cones or hammers, which can help passengers break the windows to escape when there is a fire in the vehicle or the vehicle is submerged in water.

[0003] For this reason, we previously proposed a window blasting device for passenger vehicles with a publication number of CN118182374B. Specifically, by installing blasting units on both sides of the window, when it is necessary to blast the window, the blasting units are activated to blast both sides of the window to assist passengers in escaping.

[0004] However, we found in the subsequent optimization process that the force in the blasting unit is provided by a spring. After multiple experiments, the spring has a fatigue problem, resulting in a decrease in elastic force, which has an adverse effect on the blasting operation. In addition, the blasting units are installed directly in front of both sides of the vehicle, which easily blocks the sightseeing line of sight and affects the passenger experience.

Detailed implementation manners

[0019] 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.

[0020] Please refer to Figures 1 to 9 , the present invention provides a technical solution: an escape assistance device for vehicle safety, including a frame 1 and a first installation box 12. Among them, the vehicle window 11 is installed inside the frame 1, the first installation box 12 is fixedly installed above the frame 1, and second installation boxes 13 are fixedly installed on both sides of the first installation box 12, and the two second installation boxes 13 are designed to be inclined in an "eight" shape; A first blasting component is provided on the second installation box 13, and the first blasting component is used for blasting on both sides of the vehicle window. A second blasting component is provided on the first installation box 12, and the second blasting component is used to improve the comprehensiveness of the blasting operation. A protection component is provided in the frame 1, and the protection component is used to improve the safety of escape. A falling component is provided on the second installation box 13, and the falling component is used to assist passengers in jumping out of the vehicle to escape.

[0021] The first blasting component includes a blasting module and a safety module. The blasting module includes an installation groove 2 opened in the second installation box 13. The number of installation grooves 2 is four. One side of the installation groove 2 is provided with a connecting plate 21. A first fastening bolt 22 is threadedly connected to the surface of the connecting plate 21. A screw hole adapted to the first fastening bolt 22 is opened on the surface of the second installation box 13. The connecting plate 21 is detachably connected to the surface of the second installation box 13 through the first fastening bolt 22 and the screw hole, and covers one end of the installation groove 2; One side of the connecting plate 21 is detachably connected with a guide post 23. A limiting block 24 is fixedly installed at the end of the guide post 23 away from the connecting plate 21. A power spring 25 is sleeved on the outer peripheral side of the guide post 23. A telescopic cylinder 26 is movably installed on the outer surface of the guide post 23. A first blasting cone 27 is fixedly installed at the end of the telescopic cylinder 26 close to the limiting block 24.

[0022] The safety module includes a first fixing plate 28 fixedly installed on the surface of the second installation box 13. An electric push rod 29 is fixedly installed on the first fixing plate 28. A connecting frame 210 is fixedly installed on the output shaft of the electric push rod 29. The number of connecting frames 210 is four and corresponds to the installation grooves 2 one by one. A limiting plate 211 is fixedly installed at the end of the connecting frame 210 away from the electric push rod 29. The limiting plate 211 covers the end of the installation groove 2 away from the connecting plate 21; A connecting column 212 is fixedly installed in the middle of the connecting frame 210. The four connecting frames 210 are all fixedly installed on the surface of the connecting column 212. A slider 213 is fixedly installed on the outer surface of the connecting column 212. The number of sliders 213 is three and are respectively located in the intervals where the three installation grooves 2 are connected to the installation groove 2. A chute 214 adapted to the slider 213 is opened on the surface of the second installation box 13; Both the limiting block 24 and the guide post 23 are cylindrical, and the diameter of the limiting block 24 is greater than the diameter of the guide post 23. The power spring 25 is located between the connecting plate 21 and the telescopic cylinder 26; The second blasting component includes a servo motor 3 fixedly installed at one end of the first installation box 12. A rotating shaft 31 is fixedly installed on the output shaft of the servo motor 3. Rotating arms 32 are fixedly sleeved on both sides of the outer surface of the rotating shaft 31. An arc-shaped rack 33 is fixedly installed at the end of the rotating arm 32 away from the rotating shaft 31. A second blasting cone 34 is fixedly installed at the end of the arc-shaped rack 33 away from the rotating arm 32.

[0023] Specifically, during use, the device needs to be installed above the vehicle window, with the two second mounting boxes 13 on both sides of the window. Then, a controller electrically connected to the electric push rod 29 and the servo motor 3 is installed at a position close to the passengers on the second mounting box 13, and a warning sign is set around the controller to avoid accidental touch. When the device is not in use, the first blasting cone 27 is limited in the mounting groove 2 by the limiting plate 211 to avoid accidental injury. Since the second mounting box 13 is designed to be inclined, the problem of blocking the view is optimized, preventing the impact on the passengers' sightseeing experience. When a passenger needs to break the window to escape, first start the controller, which activates the electric push rod 29 through the controller. The electric push rod 29 drives the connecting frame 210 to rise. Due to the fixation of the connecting column 212, when the connecting frame 210 fixedly connected to the output shaft of the electric push rod 29 rises, all other connecting frames 210 will follow and rise, causing the limiting plate 211 to rise. After the limiting plate 211 rises, it no longer limits the first blasting cone 27. Under the elastic force provided by the power spring 25, the telescopic cylinder 26 will be pushed, causing the first blasting cone 27 to impact and blast the window 11, achieving the purpose of assisting passengers in escaping. In other embodiments of the present invention, the electric push rod 29 can also be replaced by a pushing member such as an electric cylinder or an electric oil cylinder. To prevent the electric push rod 29 from being unusable due to power failure after an accident in the vehicle, during actual manufacturing, the electric push rod 29 fixedly connected to the connecting frame 210 can also be replaced by a detachable bolt. When not in use, one end of the detachable bolt is detachably fixedly connected to the connecting frame 210, and the other end is screwed onto the surface of the second mounting box 13. When in need of use, the detachable bolt is unscrewed from the surface of the second mounting box 13, and the detachable connection between the detachable bolt and the connecting frame 210 is released. Then, manually pushing the bottom connecting frame 210 can also achieve the above technical objectives of the present invention. Therefore, in actual application, the present invention can choose a manual or electric method for breaking the window according to whether the vehicle is equipped with an emergency power supply, or an electric push rod 29 is installed on one second mounting box 13, and a detachable bolt is installed on the other second mounting box 13 to achieve safety redundancy.

[0024] Furthermore, since the first blasting cone 27 is driven by the elastic force of the power spring 25, it is reusable. Before the subsequent window repair, the first blasting cone 27 needs to be pushed to reset it to the installation groove 2. However, the first blasting cone 27 is in a cone shape. In the traditional solution, when pushing the first blasting cone 27, you can only avoid the tip position of the first blasting cone 27 and push it from its edge. In addition, before the first blasting cone 27 enters the installation groove 2, it is necessary to use a tool to support it. Under the influence of the elastic force of the power spring 25, it is easy to fail to reset, causing accidental injury. The connection plate 21 and the second installation box 13 are set to be detachably connected and fixed by the first fastening bolt 22. Therefore, when resetting the first blasting cone 27, the connection plate 21 is directly removed and dragged backward to allow the first blasting cone 27 to enter the installation groove 2, and then the electric push rod 29 is started to drive the limit plate 211 to reset, and then the connection plate 21 is reset. At this time, the first blasting cone 27 will be held back by the limit plate 211, and it can be completed by pushing the connection plate 21, thereby reducing the difficulty and safety hazard of resetting the first blasting cone 27; Furthermore, during the repeated use of the power spring 25, spring metal fatigue may occur, which may affect the crushing effect of the first blasting cone 27. In the present invention, when the number of times or the time limit of use of the power spring 25 reaches a predetermined value, the connecting plate 21 and the guide column 23 may be disassembled, and then the power spring 25 may be replaced, so as to ensure the blasting effect of the first blasting cone 27. On the other hand, the car window will be in pieces after being blasted, but generally it will still be on the inside of the frame, and the passengers need to push it to break it open. In the present invention, after the electric push rod 29 is started, the servo motor 3 can also be started to drive the rotating shaft 31 to rotate, so that the rotating shaft 31 drives the rotating arm 32 to rotate, and the rotating arm 32 can drive the arc rack 33 to rotate, so that the second blasting cone 34 is flipped to perform a secondary blast on the car window 11, and the broken car window 11 can be broken open. At the same time, the secondary blasting can also avoid incomplete crushing of the first blasting cone 27, ensuring the smooth progress of the crushing operation. Of course, the servo motor 3 can also be replaced by a hand-cranked selection handle, which can also achieve the above-mentioned technical effects of the present invention and achieve the above-mentioned technical purposes of the present invention.

[0025] Example 2: Please refer to Figure 3 , Figure 6 and Figure 10 , the protection assembly includes a pressure rod 4, and the pressure rod 4 is fixedly sleeved on the two second blasting cones 34; A gear 41 is meshed on the upper side of the arc-shaped rack 33, and a gearbox 42 is fixedly installed at both ends of the inner cavity of the first installation box 12. The gear 41 is fixedly connected to the input end of the gearbox 42, and the output end of the gearbox 42 is fixedly connected to the first rotating wheel 43, and the first rotating wheel 43 is movably installed with the first installation box 12; The outer surface of the first runner 43 is drivingly connected to a transmission belt 44. One side of the transmission belt 44 away from the first runner 43 is drivingly connected to a second runner 45. One side of the second runner 45 is movably installed with a second fixing plate 46, and the second fixing plate 46 is fixedly connected to the second installation box 13. A pressing block 47 is fixedly sleeved on the outer surface of one side of the transmission belt 44; A clamping groove 48 is formed on one side of the pressing block 47. A second fastening bolt 49 is threadedly connected to the surface of the pressing block 47, and the second fastening bolt 49 is located above the clamping groove 48; The two gearboxes 42 are arranged in mirror symmetry, and the rotation directions of the output ends are the same.

[0026] On the basis of Embodiment 1, when the car window is broken and burst open, since the car window is adhered to the inner side of the frame by hot melt adhesive, after the car window is broken, there will still be broken glass adhered to the edge of the frame by the hot melt adhesive. When the passenger jumps out of the window, it is easy to be scratched by the edges and corners of the glass, posing a safety hazard; In the present invention, after the second blasting cone 34 breaks the car window 11, the pressing rod 4 will move along with the arc-shaped rack 33. When the pressing rod 4 passes by the car window 11, it will press the remaining glass on the upper side of the frame 1, causing it to break again or fall off, reducing the number of glass pieces and lowering the risk of scratching; When the arc-shaped rack 33 rotates, it will drive the gear 41 to rotate. The gearbox 42 will drive the first runner 43 to rotate, so that the first runner 43 drives the transmission belt 44. The transmission belt 44 can drive the gearbox 42 to rotate. When the transmission belt 44 is driven, it will drive the pressing block 47 to move downward. After the pressing block 47 moves downward, it will move along the edge of the frame 1. At this time, the transmission belt 44 is deformed. After the pressing block 47 passes by the frame 1, the transmission belt 44 resets. The pressing block 47 contacts the glass fragments of the car window 11, so as to press and strike the glass on both sides of the frame 1, causing it to fall off, reducing the number of glass fragments on both sides of the frame 1 and lowering the risk of the passenger being scratched; Furthermore, when the frame 1 needs to be retrimmed, first, the old hot melt adhesive inside the frame 1 needs to be radially removed. During the removal operation, the glue scraping blade can be fixed in the clamping groove 48 through the second fastening bolt 49, and then the transmission belt 44 is driven to drive the pressing block 47 to move up and down reciprocally to assist the staff in removing the glue, making the trimming more convenient; It should be noted that the gearbox 42 used in the present invention is used to optimize the power transmission and energy utilization efficiency of the servo motor 3, such as the rotation speed of the servo motor 3. In actual use, in order to reduce the manufacturing cost, the rotation speed of the servo motor 3 can also be controlled by a controller, and these all belong to the prior art, and the present invention will not elaborate too much here.

[0027] Embodiment 3: Please refer to Figure 1, the falling component includes a support column 5. The support column 5 is fixedly installed between two second mounting boxes 13. Above the inner sides of the two second mounting boxes 13, a first sunshade curtain 51 is adhesively bonded. The upper side of the first sunshade curtain 51 is movably installed with the support column 5. A magnetic ring 52 is adhesively bonded to the side of the first sunshade curtain 51 away from the support column 5. The closer sides of the two magnetic rings 52 are the attracting sides; Below the inner sides of the two second mounting boxes 13, a second sunshade curtain 53 is adhesively bonded. And the lower side of the second sunshade curtain 53 and the second mounting box 13 are fixedly connected by screws. An easy tear line 54 is provided between the second sunshade curtain 53 and the first sunshade curtain 51 and they are connected through the easy tear line 54; A tear opening is provided at the part of the first sunshade curtain 51 above the support column 5. Both the first sunshade curtain 51 and the second sunshade curtain 53 are of a folding design.

[0028] When there is no crushing operation, the first sunshade curtain 51 and the second sunshade curtain 53 can shield sunlight and maintain privacy as sunshade curtains. When the crushing operation is carried out, the first sunshade curtain 51 and the second sunshade curtain 53 can be separated through the easy tear line 54, and the first sunshade curtain 51 can be torn off from the second mounting box 13 and the support column 5 and placed on the lower side of the inner cavity of the frame 1 to prevent the glass fragments on its lower side from scratching the passengers; Furthermore, since tour buses are often of the bus type and there is a certain distance between the windows and the ground, when passengers jump out of the window, it is easy to get injured due to the excessive height. In the present invention, the upper side of the second sunshade curtain 53 can be torn off and tightened into a strip shape, and then the second sunshade curtain 53 can be used to jump out of the frame 1, reducing the distance between the passengers and the ground and reducing the risk of injury to the passengers, further increasing the probability of the passengers getting out of danger smoothly.
