Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0043] Buses, as a form of public transportation, are widely used in residents' daily lives. However, due to their large passenger capacity, passengers are often trapped inside the carriage after an accident, increasing the risk of injury or death. Traditional buses are required by regulations to have multiple emergency exits for passengers to escape quickly. However, in practice, passengers often have to escape through small exits such as emergency doors, emergency windows, or safety roof windows, resulting in low escape efficiency and failing to meet the escape needs of buses with large passenger capacities.

[0044] The inventors of this application discovered through research that during a bus accident, passengers often become crowded together, making movement difficult. In such situations, passengers typically choose emergency doors, emergency windows, or roof windows to escape because these exits are relatively easy to open; however, their efficiency is low. Furthermore, in a crowded situation, passengers generally cannot easily break the four corners of the rear window with an emergency hammer, thus making escape through the rear window difficult and relatively inefficient.

[0045] In view of this, this application proposes a vehicle that includes a rear window escape device. This device aims to address the problem that passengers in traditional buses often can only escape through small exits such as emergency doors, emergency windows, or safety roof windows, resulting in low escape efficiency and difficulty in meeting the escape needs of buses with large passenger capacities. It should be noted that any vehicle including the rear window escape device described in this application falls under the category of vehicles proposed in this application. Figures 1 to 7This is a schematic diagram of an embodiment of the rear window escape device proposed in this application.

[0046] Please see Figures 1 to 4 The rear window escape device 100 proposed in this application is installed on the rear window 210 of the bus 200. The rear window escape device 100 includes a window breaker 1, a support device 2, and a receiving device 3. The window breaker 1 is located close to the rear window 210 of the bus 200 and is configured to break the rear window 210 of the bus 200 in an emergency.

[0047] The support device 2 is located on the outside of the bus 200 and below the rear window 210. The support device 2 includes a support plate 21 rotatably mounted on the outer wall of the bus 200 body about an axis extending along a first direction M. During rotation, the support plate 21 has an initial position in contact with the bus 200 body and a support position parallel to the horizontal plane. The support plate 21 is configured to support passengers climbing out of the rear window 210 of the bus 200 in the support position. A receiving member 3 is movably mounted on the support plate 21. The receiving member 3 has a grounding position during movement relative to the support plate 21. When the receiving member 3 is in the grounding position, it is away from the support plate 21 and in contact with the ground.

[0048] In this technical solution, the rear window escape device 100 is installed on the rear window 210 of the bus 200. The rear window escape device 100, via the window-breaking component 1, can shatter the rear window 210 in an emergency, allowing passengers inside the vehicle to escape through the rear window 210. Furthermore, the rear window escape device 100 uses a support device 2 to support passengers climbing out of the rear window 210. Finally, the rear window escape device 100 uses a receiving component 3 to bring passengers on the support plate 21 to the ground, ensuring their safe landing and preventing secondary injuries.

[0049] Specifically, the window breaker 1 is positioned near the rear window 210 of the bus 200. In the event of an accident, the window breaker 1 can shatter the rear window 210 promptly, eliminating the need for passengers to intervene and significantly accelerating escape efficiency. The support plate 21 can actually be a cover for the engine compartment. When in its initial position, the support plate 21 can cover the engine compartment. When rotated to a horizontal support position, it will be positioned directly below the rear window 210, thus catching passengers climbing out of the rear window 210. Furthermore, the rear window 210 of the bus 200 is often quite high, and passengers jumping directly from the support plate 21 may suffer secondary injuries. Therefore, the rear window escape device 100 also includes a receiving element 3. The receiving element 3 provides multiple spaced-apart stepping positions for passengers from top to bottom, and when in the grounding position, the receiving element 3 can contact the ground, allowing passengers to return to the ground more smoothly. The rear window escape device 100 proposed in this application can break the rear window 210 on its own and help passengers escape smoothly from the rear window 210, thereby greatly improving the escape efficiency of the bus 200 and effectively reducing casualties in the event of an accident.

[0050] In practical applications, the bus 200 can also be equipped with a control switch electrically connected to the window breaker 1, and the control switch is located near the driver's seat. In the event of an accident, the driver or a passenger can promptly trigger the control switch, causing the window breaker 1 to shatter the rear window 210. Furthermore, the support plate 21 can also be electrically connected to the control switch, so that when the control switch is triggered, the support plate 21 will promptly rotate to the support position to support passengers climbing out of the rear window 210.

[0051] Please see Figure 3 and Figure 4 In some embodiments, the supporting device 2 further includes a rotating rod 22 and a driving device 23. The rotating rod 22 is rotatably mounted on the body of the bus 200 about an axis extending along a first direction M. A plurality of connecting portions 221 are spaced apart at the center of the rotating rod 22, and the plurality of connecting portions 221 are respectively connected to the supporting plate 21. The driving device 23 is drivenly connected to the rotating rod 22 to drive the rotating rod 22 to rotate when the rear window 210 of the bus 200 is broken.

[0052] The two ends of the rotating rod 22 are rotatably mounted on the body of the bus 200 about an axis extending along the first direction M, and the middle part of the rotating rod 22 is connected to the support plate 21 through multiple connecting parts 221. The support device 2 can drive the rotating rod 22 to rotate through the drive device 23, so the drive device 23 can drive the support plate 21 to rotate relative to the body to the support position.

[0053] There are many specific implementations of the drive device 23. For example, the drive device 23 can drive the rotating rod 22 to rotate via a motor and its output shaft. Alternatively, the drive device 23 can drive a rack to move via a cylinder, and then drive the rotating rod 22 to move via the rack. Of course, the drive device 23 can also directly lift the support plate 21 via a cylinder, causing the support plate 21 to rotate. Therefore, the specific implementation of the drive device 23 is not specifically limited here and can be adjusted according to the actual situation.

[0054] Please see Figure 4 and Figure 5 In some embodiments, the rotating rod 22 is provided with an abutment 222 extending radially therein. The supporting device 2 also includes a limiting member 24 provided on the body of the bus 200, the limiting member 24 being provided with an elongated hole 241 for the abutment 222 to pass through. The extending direction of the elongated hole 241 is corresponding to the movement trajectory of the abutment 222, so that when the supporting plate 21 rotates, the abutment 222 can move within the elongated hole 241, and when the supporting plate 21 moves to the initial position and the supporting position, the abutment 222 abuts against both ends of the elongated hole 241 respectively.

[0055] When the driving device 23 drives the rotating rod 22 to move, the abutment 222 on the rotating rod 22 moves within the elongated hole 241 on the limiting member 24. It should be noted that the extension direction of the elongated hole 241 corresponds to the movement trajectory of the abutment 222. Therefore, when the support plate 21 moves back and forth between the initial position and the bearing position, the interior of the elongated hole 241 does not interfere with the movement of the abutment 222. However, when the support plate 21 moves away from the initial and bearing positions, both ends of the elongated hole 241 abut against the abutment 222, thereby restricting the rotation of the rotating rod 22 and consequently restricting the movement of the support plate 21. By setting the limiting member 24 to cooperate with the abutment 222 on the rotating rod 22, the support device 2 prevents the support plate 21 from moving beyond the initial and bearing positions, ensuring the normal operation of the support plate 21.

[0056] Please see Figure 6 and Figure 7 In some embodiments, the connecting member 3 includes a ladder 31, one end of which is hinged to the support plate 21 so that the ladder 31 can rotate relative to the support plate 21, and the other end of the ladder 31 is detachably connected to the support plate 21.

[0057] Specifically, one end of the ladder 31 is hinged to the support plate 21, allowing the ladder 31 to rotate around the support plate 21. The other end of the ladder 31 is detachably connected to the support plate 21, enabling the ladder 31 to be fixed to the support plate 21 when not in use, without affecting the normal operation of the vehicle. After a passenger climbs onto the support plate 21 from the rear window 210, the passenger can detach the ladder 31 from the support plate 21, lower the ladder 31, and safely climb the ladder 31 to the ground.

[0058] In addition, the receiving component 3 can also receive passengers in other ways. For example, the receiving component 3 can also include a rope ladder, one end of which is connected to the support plate 21. When using it, passengers only need to lower the rope ladder directly without any additional operation, which is very convenient.

[0059] After an accident, passengers are often in a state of high anxiety, making them more prone to making mistakes when climbing the ladder 31. Therefore, the ladder 31 needs to remain stable during use. In some embodiments, the ladder 31 has a storage position that engages with the support plate 21 and a working position away from the storage position during rotation. The receiving member 3 also includes a first limiting part 32 and a second limiting part 33, which are positioned opposite each other on both sides of the ladder 31 in the working position. The first limiting part 32 and the second limiting part 33 are configured to limit the ladder 31 to the working position. When the ladder 31 moves to the working position, one side of the ladder 31 abuts against the first limiting part 32, and the other side abuts against the second limiting part 33, thereby limiting the ladder 31 to the working position, making the ladder 31 more stable in the working position and facilitating passenger climbing.

[0060] In some embodiments, the ladder 31 is located on the side of the support plate 21 away from the rear window 210 of the bus 200. The support plate 21 has a mounting cavity communicating with the outside, and the opening of the mounting cavity is positioned opposite to the ladder 31 in the storage position. The connecting member 3 also includes an integrally formed mounting shaft 34 and a connecting member 35. The mounting shaft 34 is rotatably mounted on the support plate 21, and the connecting member 35 is connected to the ladder 31.

[0061] The first limiting part 32 includes a stop 321 disposed in the mounting cavity. The stop 321 is configured to extend at least partially out of the mounting cavity and abut against the ladder 31 in the working position when the ladder 31 is removed from the storage position. The second limiting part 33 includes a limiting baffle 331. One end of the limiting baffle 331 is connected to the support plate 21 and extends toward the side of the ladder 31 in the working position away from the stop 321. The limiting baffle 331 is configured to abut against the connector 35 in the working position.

[0062] Specifically, when the ladder 31 is in the retracted position, it is in contact with the support plate 21. At this time, the stop 321 is pushed into the mounting cavity by the ladder 31 and is not exposed to the outside. When the ladder 31 moves from the retracted position to the working position, the bottom of the stop 321 loses the support of the ladder 31, so a part of the stop 321 extends out of the mounting cavity and abuts against the ladder 31. In addition, the limiting baffle 331 is itself located on the other side of the ladder 31 relative to the stop 321. Therefore, when the ladder 31 moves from the retracted position to the working position and a part of the stop 321 extends out of the mounting cavity, the stop 321 and the limiting baffle 331 can limit the ladder 31 in the working position.

[0063] When ladder 31 needs to be reset, maintenance personnel need to first push the stop block 321 into the mounting cavity, so that ladder 31 can rotate toward the storage position and return to the storage position. After ladder 31 is attached to the support plate 21, the end of ladder 31 that was previously away from the support plate 21 can be detachably connected to the support plate 21 to complete the storage of ladder 31.

[0064] The rear window 210 of the bus 200 is generally at a relatively high height from the ground, so the ladder 31 may not be long enough to help passengers return to the ground in actual use. Therefore, in some embodiments, the ladder 31 includes a first section 311 and a second section 312 that are nested together in sequence, with the first section 311 hinged to the support plate 21. One of the first section 311 and the second section 312 is provided with a groove extending along its extension direction, and the other corresponding groove of the first section 311 and the second section 312 is provided with a slider so that the second section 312 can slide out from the first section 311.

[0065] In practical applications, when a passenger lowers the ladder 31, the second section 312 will naturally slide off the first section 311 due to its own weight, thus extending the total length of the ladder 31. Specifically, one of the first section 311 and the second section 312 is provided with a groove extending along its extension direction, and the other corresponding groove of the first section 311 and the second section 312 is provided with a slider, allowing the first section 311 and the second section 312 to slide relative to each other. Furthermore, when the slider moves to one end of the groove, the slider and the side wall of the groove will abut against each other, thereby stopping the first section 311 and the second section 312 from moving and preventing the first section 311 and the second section 312 from separating.

[0066] Please see Figure 4 and Figure 7 In some embodiments, the supporting device 2 further includes a spring lock 25 corresponding to the ladder 31 disposed on the supporting plate 21, so as to detachably connect the ladder 31 to the supporting plate 21. The spring lock 25 can stably fix the ladder 31 to the supporting plate 21, and the unlocking of the spring lock 25 is relatively convenient and simple, and passengers can also open it smoothly in an emergency.

[0067] Please see Figures 1 to 2 In practical applications, when the ladder 31 is located on the side of the support plate 21 near the rear window 210 of the bus 200, passengers will inevitably come into contact with the ladder 31 when climbing from the rear window 210 onto the support plate 21, and the ladder 31 may also interfere with the passengers' escape. Therefore, in some embodiments, the ladder 31 is located on the side of the support plate 21 away from the rear window 210 of the bus 200, and the support plate 21 is provided with an operating window 211 corresponding to the ladder 31. The operating window 211 is configured to allow passengers to reach their hands to the other side of the support plate 21 to disassemble and release the ladder 31.

[0068] When the ladder 31 is located on the side of the support plate 21 away from the rear window 210 of the bus 200, passengers may have difficulty lowering the ladder 31 off the support plate 21. Therefore, the support plate 21 is provided with an operating window 211 corresponding to the ladder 31. The operating window 211 is constructed so that passengers can reach their hands to the other side of the support plate 21, thereby enabling passengers to lower the ladder 31 more easily and escape.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
