Description

Technical Field

[0001] This utility model relates to bus accessories, and in particular to an outward-opening emergency window for buses. Background Technology

[0002] Currently, most passenger buses use fixed side windows, which improves the vehicle's sealing, safety, and comfort. However, in emergencies such as traffic accidents or fires, these fixed windows can restrict passengers' rapid escape routes. Although existing buses typically equip windows with emergency hammers or one-button window-breaking devices, several problems remain in actual use. For example, using an emergency hammer requires passengers to have certain operating skills and sufficient striking force, especially in emergencies where passengers are often tense and unable to break the window quickly and effectively. While one-button window-breaking devices improve efficiency, passengers may still be cut by sharp glass edges when escaping through the window after the glass is broken, posing a significant safety hazard.

[0003] Therefore, some buses have begun to adopt emergency escape windows to replace traditional window-breaking escape methods. These escape windows are typically located on the side of the carriage and have an openable structure, allowing passengers to quickly open and escape in emergencies, thus improving escape efficiency and safety. However, while these openable emergency escape windows offer convenience, they also bring new problems: in non-emergency situations, some passengers may open the emergency escape windows out of curiosity or other reasons, which not only affects the normal operation of the vehicle but may also adversely affect the vehicle's sealing and safety, and could even lead to safety accidents.

[0004] Since bus drivers are usually located at the front of the vehicle, it is difficult for them to effectively monitor the behavior of passengers inside the carriage while the vehicle is in motion. Therefore, how to prevent passengers from opening emergency escape windows at will while ensuring emergency escape functions has become an urgent technical problem to be solved. Utility Model Content

[0005] This invention proposes an outward-opening emergency window for buses, which allows drivers to easily monitor whether passengers can open the emergency escape window at will, thus solving the aforementioned problems existing in the use of existing technologies.

[0006] The technical solution of this utility model is implemented as follows: A push-out emergency window for passenger vehicles includes an inner frame and an outer frame. The inner frame has a window in the middle, and the window is covered with glass. The upper side of the inner frame is hinged to the outer frame. An air spring is provided between the two sides of the inner frame and the outer frame. One end of the air spring is hinged to the outer frame, and the other end is hinged to the inner frame. A locking mechanism is provided between the lower side of the inner frame and the outer frame. The locking mechanism includes a lock body fixed on the inner frame and a bolt fixed on the lower side of the outer frame. The lock body has a lock opening for the bolt to enter. A lock plate is rotatably connected to the lock body. The lock plate includes a stop for limiting the bolt in the lock opening. A linkage plate that is rotatably connected to the lock body and works in conjunction with the lock plate is also connected to the lock body. A window opening handle is provided on the inner frame. A pull rope is connected between the window opening handle and the linkage plate. A micro switch is provided on the lock body located on one side of the linkage plate. An alarm circuit board electrically connected to the micro switch is provided inside the window opening handle. An alarm horn is provided on the alarm circuit board.

[0007] Preferably, the inner frame has an opening, and a handle seat is fixedly connected to the inner frame at the opening. The window handle is rotatably connected to the handle seat, and a return torsion spring is provided between the window handle and the handle seat. One end of the window handle passes through the opening and is fixedly connected to the pull rope.

[0008] Preferably, the window handle is covered with a handle cover, and the inner frame is fixedly connected to an upper connecting seat and a lower connecting seat on the upper and lower sides of the window handle, respectively. The lower end of the handle cover is rotatably connected to the connecting seat. The upper end of the handle cover is provided with a connecting round hole and an interference fit through one side of the handle cover. The upper connecting seat is provided with a connecting post for engaging in the connecting round hole.

[0009] Preferably, the inner frame has a hollow space inside, the handle seat is installed in the hollow space, the window handle has a wire outlet on both the upper and lower sides near the handle seat, the inner frame has a first wire guide seat near its upper side, and the outer frame has a second wire guide seat near the first wire guide seat on its upper side.

[0010] Preferably, there are two locking mechanisms. The inner frame has an inlet on the lower side of the handle seat that penetrates into the hollow space. The inner frame also has outlets on one side of each locking mechanism that penetrate into the hollow space. The pull rope is divided into two strands that enter the hollow space through the inlet and extend out from the two outlets to connect with the linkage plate of their respective locking mechanisms.

[0011] Preferably, the outer frame has a hook groove on its upper side, the inner frame has a hanging section on its upper side for rotating and engaging with the hook groove, and the outer frame has a plastic bushing on the hook groove and on its upper side.

[0012] Preferably, the outer frame is provided with a first sealing strip and a second sealing strip. The first sealing strip is located between the upper side of the outer frame and the upper side of the inner frame, and between the outer frame and the glass. The second sealing strip is located between the upper side of the outer frame and the inner frame.

[0013] Preferably, the outer frame is fixedly connected with limiting blocks located on both sides of the inner frame.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] 1. This application provides a push-out emergency window for passenger vehicles. By incorporating an openable structure between the inner and outer frames and a locking plate and stop block in the locking mechanism, the emergency window is reliably locked, preventing unauthorized opening in non-emergency situations. Simultaneously, a pull cord is installed between the window handle and the linkage plate, allowing passengers to rotate the linkage plate when opening the emergency window, thereby unlocking the locking plate. The rotation of the linkage plate triggers a microswitch, and the alarm circuit board, upon receiving the signal, controls the alarm horn to sound, providing real-time alerts of the opening action. This facilitates driver monitoring and effectively prevents accidental or malicious opening. This structure is simple, reliable, and highly integrated, enhancing the safety and practicality of the emergency window.

[0016] 2. The window handle is covered with a handle cover, which not only improves the overall neatness of the appearance but also protects the handle structure. More importantly, the handle cover design effectively prevents passengers from accidentally touching or opening the emergency window in non-emergency situations, providing physical protection and a warning function, and enhancing the emergency window's anti-accidental activation function.

[0017] 3. Two locking mechanisms are provided to further enhance the locking stability when the emergency window is closed.

[0018] 4. By setting hook grooves on the outer frame and mounting sections on the inner frame, the inner frame can be stably rotated and connected to the outer frame, improving the flexibility of opening and closing the emergency window. At the same time, the plastic bushings at the hook grooves effectively reduce friction and collision between the aluminum alloy materials, reduce noise generated during rotation, improve the overall vehicle ride comfort, and extend service life.

[0019] 5. By setting a first sealing strip and a second sealing strip on the outer frame, respectively, the gaps between the outer frame and the glass, and between the outer frame and the inner frame are sealed, which effectively improves the overall sealing performance of the emergency window and prevents rainwater from seeping into the interior of the vehicle.

[0042] The following will refer to the appendix in the embodiments of this utility model. Figure 1-20 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] Example 1:

[0044] like Figures 1 to 17As shown, this utility model discloses an outward-opening emergency window for passenger vehicles, including an inner frame 1 and an outer frame 2. A window 11 is located in the middle of the inner frame 1, and glass 12 covers the window 11. The glass is bonded to the inner frame with a glass adhesive. The upper side of the inner frame 1 is hinged to the outer frame 2, and an air spring 3 is provided between the two sides of the inner frame 1 and the outer frame 2. One end of the air spring 3 is hinged to the outer frame 2, and the other end is hinged to the inner frame 1. The air spring 3 provides elastic support to push the inner frame 1 outward, so that after unlocking, passengers only need to apply slight force to push the inner frame 1 outward a certain distance, and the inner frame will open automatically under the elastic force of the air spring 3. Simultaneously, the air spring 3 also provides support, eliminating the need for manual assistance and facilitating the escape of passengers. Furthermore, a locking mechanism is provided between the lower side of the inner frame 1 and the outer frame 2, such as... Figure 8 as well as Figures 14 to 17 As shown, the locking mechanism specifically includes a lock body 41 fixed to the inner frame 1 and a bolt 42 fixed to the lower side of the outer frame 2. A lock opening 411 for the bolt 42 to enter is provided on the lock body 41. A lock plate 43 is rotatably connected to the lock body 41. The lock plate 43 includes a stop 431 for limiting the bolt 42 within the lock opening 411. A linkage plate 44, which is linked and cooperates with the lock plate 43, is also rotatably connected to the lock body 41. Figure 16 and 17 As shown, a torsion spring 45 is provided between the linkage plate 44 and the locking plate 43. The locking plate 43 has a first inclined locking block 432, while the linkage plate 44 has a second inclined locking block 441. The first inclined locking block 432 and the second inclined locking block 441 abut against each other, maintaining a stable relationship between the linkage plate 44 and the locking plate 43 when locked. When the linkage plate 44 is rotated, the second inclined locking block 441 passes over the first inclined locking block 432. Then, as the linkage plate 44 rotates, the torsion spring 45 drives the locking plate 43 to rotate, causing the stop block 431 on the locking plate 43 to no longer limit the bolt 42 within the lock opening 411. Furthermore, during the rotation of the locking plate 43, the bolt 42 is pushed outwards from the lock opening 411. This is the unlocking process for opening the window. Further, as... Figure 8 As shown, a window opening handle 51 is provided on the inner frame 1, and a pull rope 6 is connected between the window opening handle 51 and the linkage plate 44. Therefore, by rotating the window opening handle 51, the pull rope 6 can be driven to pull the linkage plate 44, thereby driving the lock plate 43 to unlock. In addition, as shown in Figures 15-17, a micro switch 7 is provided on the lock body 41 located on one side of the linkage plate 44, and as shown in Figures 15-17... Figure 12As shown, the window handle 51 is equipped with an alarm circuit board 8 electrically connected to the micro switch 7. The alarm circuit board 8 is equipped with an alarm horn 81. When a passenger operates the window handle 51, the pull rope 6 drives the linkage plate 44 and pushes the micro switch 7. After receiving the signal, the alarm circuit board 8 immediately activates the alarm horn 81 to sound, reminding the driver to pay attention to the emergency window being opened, thereby achieving effective monitoring of passenger behavior.

[0045] like Figure 5 and Figure 8 As shown, an opening 13 is provided on the inner frame 1, and a handle seat 52 is fixedly connected to the inner frame 1 at the opening 13 position. The window handle 51 is rotatably connected to the handle seat 52. A reset torsion spring 53 is provided between the window handle 51 and the handle seat 52. The reset torsion spring 53 is used to reset the window handle 51 after it is rotated. One end of the window handle 51 passes through the opening 13 and is fixedly connected to the pull rope 6.

[0046] like Figure 2 Figure 5 Figure 10 as well as Figure 11 As shown, a handle cover 54 is provided over the window handle 51. An upper connecting seat 55 and a lower connecting seat 56 are fixedly connected to the upper and lower sides of the window handle 51, respectively, within the inner frame 1. The upper connecting seat 55 and the lower connecting seat 56 are not directly connected to the window handle 51, but the upper side of the window handle 51 will abut against the upper connecting seat 55 due to the action of the return torsion spring 53. For example... Figure 10 As shown, the lower end of the handle cover 54 is rotatably connected to the connecting seat, as... Figure 11 As shown, the upper end of the handle cover 54 has a connecting hole 541 and an interference fit 542 that extends through one side of the handle cover 54. The upper connecting seat 55 has a connecting post 551 for engaging in the connecting hole 541. When in use, a certain amount of force is required to rotate the upper side of the handle cover 54 downwards to expose the window handle 51. The design of the handle cover 54 not only protects the handle structure, but more importantly, it effectively prevents passengers from accidentally touching or maliciously opening the emergency window in non-emergency situations, thus improving overall safety.

[0047] like Figure 7 and Figure 8As shown, a hollow space 14 is provided inside the inner frame 1, and the through-hole 13 passes through the hollow space 14. Therefore, the handle base 52 is also installed in the hollow space 14. The window handle 51 has a wire outlet 511 on both the upper and lower sides near the handle base 52. The wire outlet 511 is used for the wires of the alarm circuit board 8 to pass through and enter the hollow space 14. The inner frame 1 has a first wire guide 15 near its upper side, and the outer frame 2 has a second wire guide 21 near the first wire guide 15 on its upper side. The wires passing through the lower wire outlet 511 are connected to the micro switch 7. The wires passing through the upper wire outlet 511 reach the first wire guide 15 in the hollow space 14 and then pass through the second wire guide 21, and then connect to the power supply of the bus.

[0048] like Figure 6 As shown, the locking mechanism has two parts, which further enhances the locking stability when the emergency window is closed. Figure 8 As shown, the inner frame 1 has an inlet 16 on the lower side of the handle seat 52 that penetrates into the hollow space 14, and the inner frame 1 has an outlet 17 on one side of each of the two locking mechanisms that penetrates into the hollow space 14. The pull rope 6 is divided into two strands that enter the hollow space 14 through the inlet 16 and extend out from the two outlets 17 to connect with the linkage plate 44 of their respective locking mechanisms. It should also be noted that the wire that passes through the lower outlet 511 into the hollow space 14 also passes through the outlet 17 and connects to the micro switch 7.

[0049] like Figure 9 As shown, the specific structure of the hinge connection between the upper side of the inner frame 1 and the outer frame 2 is as follows: a hook groove 22 is provided on the upper side of the outer frame 2, and a hanging section 18 for rotating and engaging with the hook groove 22 is provided on the upper side of the inner frame 1. The outer frame 2 is provided with a plastic bushing 23 on the hook groove 22 and the upper side of the hook groove 22. The plastic bushing 23 can effectively reduce the friction and collision between aluminum alloy materials, reduce the noise generated during rotation, improve the ride comfort of the whole vehicle, and extend the service life.

[0050] like Figure 4 As shown Figure 7 As shown, a first sealing strip 24 and a second sealing strip 25 are provided on the outer frame 2. The first sealing strip 24 is located between the upper side of the outer frame 2 and the upper side of the inner frame 1, and between the outer frame 2 and the glass 12. Specifically, the uppermost first sealing strip 24 is located between the upper side of the outer frame 2 and the upper side of the inner frame 1, while the other first sealing strips 24 are located between the outer frame 2 and the glass 12. The multiple second sealing strips 25 are all located between the upper side of the outer frame 2 and the inner frame 1. It should be noted that the first sealing strip 24 and the second sealing strip 25 will be compressed and deformed during actual use to form a seal. Figure 7The positions of the first sealing strip 24 and the second sealing strip 25 are for reference only and do not imply that the first sealing strip 24 and the second sealing strip 25 will pass through the inner frame 1 and the glass 12.

[0051] like Figure 4-6 As shown, the outer frame 2 is fixedly connected to the limiting blocks 26 located on both sides of the inner frame 1. The rubber limiting blocks 26 can position the inner frame 1 to prevent it from swaying left and right and have a buffering effect when vibrating.

[0052] Example 2:

[0053] like Figure 18-20 As shown, Embodiment 2 is basically the same as Embodiment 1, except that the structure of the outer frame 2 and the setting of the glass 12 are slightly different from Embodiment 1. In Embodiment 2, the glass 12 covers the outer frame 2 except for the upper side, which makes it more aesthetically pleasing.

[0054] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
