Description

Technical Field

[0001] The utility model relates to the technical field of rotatable windows and windshields of general vehicles, and in particular to an emergency window and a vehicle. Background Art

[0002] Due to their large size and the large number of passengers they accommodate, buses experience significant inertia while driving, increasing the probability of traffic accidents. To prevent passengers from being trapped in the event of an accident, buses are equipped with emergency escape windows on both sides. In the event of an accident and the doors cannot be opened, passengers can open the emergency escape windows to save themselves. Traditional bus windows are sliding, with the two windows opening in opposite directions. If used as emergency escape windows, passengers could easily argue over which window to open, missing their best chance to escape. To prevent this, emergency escape windows have evolved into windows that are fixed to the bus body and cannot be opened. Instead, they are equipped with a safety hammer on the inside. In the event of an accident, passengers can use the hammer to shatter the window glass and escape through the window. However, the shattered glass can easily cause secondary injuries to escaping passengers.

[0003] In response to the above problems, a Chinese invention patent with authorization announcement number CN108621755B and authorization announcement date 2024.08.09 discloses an outward-pushing emergency window, which includes an inner window frame and an outer window frame, a hinge connection component, a support component, an opening and locking component and an alarm system. The outer window frame is used to bond with the vehicle body, and the inner window frame is used to bond with the glass. The inner window frame and the outer window frame both include upper and lower frame bars and side frame bars that are relatively arranged. The hinge connection component rotatably connects the upper frame bars of the inner window frame and the outer window frame, including a vehicle body connection part connected to the vehicle body, a rotating connection part rotatably connected to the vehicle body connection part, and a rotating connection part rotatably connected to the glass. The connected glass connection part and the body connection part include an ear, and the rotating connection part includes a convex head that rotates and fits in the ear. When the glass is pushed outward, the convex head rotates in the ear to realize the rotational cooperation of the inner window frame and the outer window frame; the support assembly includes a gas spring bracket and a gas spring. The gas spring is respectively connected to the side frame strips of the inner window frame and the outer window frame through the gas spring bracket. The gas spring provides assistance and support for the opening of the emergency window; the opening locking assembly is arranged on the inner window frame, and the problem of right-angle change of direction is solved by using a cable soft shaft, which specifically includes a cable guide rail and a handle. A sliding cable is installed in the cable guide rail, and cable slides are riveted on both ends of the sliding cable When the handle is pulled, the handle drives the handle pad, the cable slide, the sliding cable and the locking slider to move along the cable guide rail, the return spring is compressed, and the locking buckle moves to cooperate with the opening slot. At this time, the emergency window is unlocked and can be opened. When closing the emergency window, the emergency window is pulled back to the contact between the inner window frame and the outer window frame by the handle, and the pulling force on the handle is cancelled. The handle pad is reset under the restoring force of the return spring, and the locking buckle is engaged with the The opening slot is separated and the emergency window is locked; the alarm system includes a sound alarm, an inner frame switch and a handle switch. The inner frame switch is equipped with an outer frame magnet arranged on the outer window frame, and the handle switch is equipped with a handle magnet arranged on the inner window frame. When the handle is pulled, the handle magnet on the handle is separated from the handle switch, and the sound alarm sounds an alarm. After pushing the emergency window outward, release the handle, and the handle is reset to the point where the handle switch contacts the handle magnet. At this time, the inner frame switch is separated from the outer frame magnet, and the sound alarm still sounds an alarm. That is, the alarm will not be sounded until the handle switch and the inner frame switch are in contact with the corresponding handle magnet and outer frame magnet at the same time.

[0004] In the above-mentioned emergency window solution, the handle magnet is separated from the handle switch, and the sound alarm will sound an alarm, but at this time the inner frame switch and the outer frame magnet are not separated, that is, the emergency window is not opened or unlocked. Then, when the bus is driving, passengers may stand with the help of the handle, or accidentally touch the handle, which will cause the handle magnet to separate from the handle switch, thereby triggering frequent false alarms of the alarm system, affecting the mood of the driver and passengers; in addition, a rotating connection is provided between the glass connection part and the body connection part, and there is a step between the outer side of the glass connected to the glass connection part and the outer side of the body connection part, which affects the aesthetics of the vehicle body. If the vehicle is operated in winter, the glass of the emergency window is prone to fogging and its environmental adaptability is also poor. Utility Model Content

[0030] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0031] As an important functional part of an operating bus over 7 meters long, the emergency window needs to meet the basic function of enabling passengers to escape quickly. Before the emergency window in the existing technology is opened, the passengers will inevitably touch the handle by mistake, causing the handle magnet to separate from the handle switch, which will lead to frequent false alarms of the sound alarm, which will affect the mood of the driver and passengers. In order to avoid false alarms of the sound alarm, a switch is set at the locking part of the inner and outer window frames. The switch monitors the locking status of the inner and outer window frames and sends a signal to the alarm. The switch is set on the unlocking path of the inner and outer window frames to ensure that the switch will send a signal to the alarm only when the inner and outer window frames are unlocked. Based on the above inventive concept, the utility model proposes an emergency window and a vehicle. By matching the locking mechanism with the unlocking warning switch, the unlocking warning switch monitors the status of the locking mechanism, thereby achieving accurate alarms and avoiding false alarms.

[0032] The implementation method of the emergency window of the present utility model:

[0033] See Figures 1 to 4 As a basic embodiment of the present utility model, the emergency window includes an inner window frame 1 and an outer window frame 2. The inner window frame 1 is used to install glass 3, and the outer window frame 2 is used to be fixed to the vehicle body. A locking mechanism is provided between the inner and outer window frames. The locking mechanism includes a movable locking mechanism 4 provided on the inner window frame 1 and a fixed locking member 5 fixed on the outer window frame 2. An unlocking handle 6 is provided on the inner window frame 1 and is transmission-connected to the movable locking mechanism 4. The movable locking mechanism 4 has a locking position for cooperating with the fixed locking member 5 to lock the inner and outer window frames 2 and an unlocking position for unlocking the inner and outer window frames 2. In addition, an unlocking warning switch 7 is also provided on the inner window frame 1, and the unlocking warning switch 7 is connected to a warning device 8. The moving contact 9 of the unlocking warning switch 7 is arranged on the movable path of the movable locking mechanism 4. When the movable locking mechanism 4 is in the locked position, the unlocking warning switch 7 is in the state of turning off the alarm 8. When the movable locking mechanism 4 moves to the unlocking position, the unlocking warning switch 7 is triggered by the movable locking mechanism 4 and switched to the state of turning on the alarm 8. When the emergency window needs to be opened, the movable locking mechanism 4 can be moved from the locked position to the unlocking position by pulling the unlocking handle 6, thereby unlocking the inner window frame 1 and the outer window frame 2. Only when the movable locking mechanism 4 moves to the unlocking position will the unlocking warning switch 7 be triggered, thereby greatly reducing the probability of the alarm 8 being triggered by mistake.

[0034] As a preferred embodiment of the present invention, the fixed locking member 5 is a lock pin, and the movable locking mechanism 4 includes a lock plate 10 rotatably assembled on the inner window frame 1 and a ratchet plate 11 cooperating with the lock plate 10. The lock plate 10 is rotatably connected to the inner window frame 1 and a torsion spring is provided between the two. A bayonet 12 cooperating with the lock pin is provided on the lock plate 10. When the movable locking mechanism 4 is in the locked position, the lock pin is engaged in the bayonet 12 and limits the lock plate 10. When the movable locking mechanism 4 is in the unlocked position, it pushes the inner window frame 1. The lock plate 10 can be driven by the lock pin to rotate when the inner window frame 1 is opened to release the lock pin, thereby realizing the separation of the inner window frame 1 and the outer window frame 2. While the lock plate 10 is driven to rotate by the lock pin, the torsion spring is twisted and causes the lock plate 10 to maintain the rotation angle when separated from the lock pin. When the emergency window needs to be closed, the emergency window is pulled inward until the lock pin enters When the door is unlocked, the ratchet plate 11 is in engagement with the latch 10, and the latch 10 is in engagement with the latch 10. When the door is unlocked, the ratchet plate 11 is engaged with the latch 10, and the latch 10 is engaged with the latch 10. When the door is unlocked, the ratchet plate 11 is engaged with the latch 10, and the latch 10 is engaged with the latch 10. Figure 4 , Figure 4 The solid line part in the figure represents the position state of the lock plate 10 and the ratchet plate 11 in the locked position, and the dotted line part represents the position state of the lock plate 10 and the ratchet plate 11 in the unlocked position. When the inner and outer window frames are locked, the lock plate 10 is pressed against the ratchet plate 11 and locked by the lock pin and cannot be rotated. When the inner and outer window frames are unlocked, the unlocking handle 6 first drives the ratchet plate 11 to rotate from the locked position to the unlocked position, and then pushes the inner window frame 1 outward. The lock plate 10 moves with the inner window frame 1 and is driven by the lock pin to rotate from the locked position to the unlocked position until the lock pin is separated from the bayonet 12, so that the inner and outer window frames can be unlocked. In other embodiments, at least two movable locking mechanisms 4 are provided, and the two movable locking mechanisms 4 are symmetrically arranged on the lower frame bar of the inner window frame 1. Such an arrangement can make the locking between the inner window frame 1 and the outer window frame 2 more reliable, avoid the formation of a gap between the inner window frame 1 and the outer window frame 2, or even prevent the inner window frame 1 from warping or tilting. Long-term tilting can cause the inner window frame 1 to be unable to lock with the outer window frame 2, thereby ensuring the airtightness of the emergency window in the locked state. In other embodiments, the fixed locking member 5 can also be configured as a columnar rod or a bolt, as long as it can cooperate with the bayonet 12 on the lock plate 10.

[0035] As a preferred embodiment of the present invention, the ratchet plate 11 is connected to the unlocking handle 6 through a pull wire 13, and the pull wire 13 is used to drive the ratchet plate 11 to rotate. When the unlocking handle 6 is pulled, the pull wire 13 moves accordingly and drives the ratchet plate 11 to rotate accordingly, and the limit of the ratchet plate 11 on the lock plate 10 disappears. At this time, the inner window frame 1 is pushed outward, and the lock plate 10 is driven by the lock pin to rotate and separate from the lock pin, thereby realizing the opening of the inner window frame 1. The entire unlocking process is simple and convenient, which can reduce the process time for passengers to open the emergency window and increase the probability of passengers' escape; when the emergency window needs to be closed, an inward pulling force is first applied to the inner window frame 1 until the inner window frame 1 moves to the bayonet 12 and contacts the lock pin again. The lock pin drives the lock plate 10 to rotate and reset, and then the ratchet plate 11 rotates and resets under the action of the pull wire 13 and presses against the lock plate 10 again, and the lock plate 10 is in the locked position again.

[0036] See Figure 5 As a preferred embodiment of the present invention, the inner and outer window frames 2 are rotatably connected by a hinge structure 14. The glass 3 installed on the inner window frame 1 can form a fully flat structure with the outer surface of the outer window frame 2 when the movable locking mechanism 4 is in the locked position. The hinge structure 14 includes a hinge hook 15. The hinge hook 15 is located on the upper frame bar of the outer window frame 2. The upper frame bar of the inner window frame 1 is provided with a rotating bead 16 that cooperates with the hinge hook 15. The rotating bead 16 can flip in the hinge hook 15, thereby driving the inner window frame 1 to flip outward. A double-layer sealing strip 17 is also provided between the inner window frame 1 and the outer window frame 2 to ensure the sealing between the inner window frame 1 and the outer window frame 2. The hinge structure 14 is a prior art and will not be described here.

[0037] See Figure 6 As a preferred embodiment of the present invention, a hidden gas support structure 18 is further provided between the inner and outer window frames 2. The hidden gas support structure 18 is provided in two groups and is respectively provided on the side frame strips of the inner window frame 1 and the outer window frame 2. The hidden gas support structure 18 includes two support brackets 19 respectively provided on the inner and outer window frames and a gas spring 20 connected between the two support brackets 19. The hidden gas support structure 18 can provide assistance for opening the emergency window and provide support for the emergency window after opening. When the emergency window is closed, the hidden gas support structure 18 is hidden between the inner window frame 1 and the outer window frame 2, and has good aesthetics. The hidden gas support structure 18 is a prior art and will not be described here.

[0038] See Figure 7As a preferred embodiment of the present invention, a cold-proof and heat-insulating structure 21 is provided on the outer window frame 2. This cold-proof and heat-insulating structure 21 includes a cotton frame 22 and thermal insulation cotton 23. The cotton frame 22 is mounted on the inner surface of the outer window frame 2, and the thermal insulation cotton 23 is sandwiched within a cotton space 24 formed by the cotton frame 22 and the outer window frame 2. This arrangement prevents frost from forming on the surface of the glass 33 during winter driving, thereby improving the winter riding experience. In other embodiments, an electric heater may be provided within the cotton space 24, as long as it can provide heat to prevent frost from forming on the surface of the glass 33.

[0039] See Figure 8 As a preferred embodiment of the present invention, a semi-hidden handle 25 is provided on the lower frame strip of the inner window frame 1. The semi-hidden handle 25 is of convex design and can constitute a pulling point for closing the emergency window, that is, the lower half of the semi-hidden handle 25 is embedded in the lower frame strip of the inner window frame 1, and the upper half is convex outside the lower frame strip of the inner window frame 1. When closing the emergency window, the emergency window can be pulled and closed by placing the fingers in the concave lower half or by holding the convex upper half. This arrangement provides two ways to close the emergency window, and can save more effort in the process of closing the emergency window, making the internal device of the vehicle body more beautiful.

[0040] See Figure 9 As a preferred embodiment of the present invention, the unlocking handle 6 is rotatably connected to the inner window frame 1 through the handle base 26, and the alarm 8 is integratedly installed on the unlocking handle 6. The handle base 26 is connected to the wiring harness 27 and the signal transmission harness 28. The wiring harness 27 and the signal transmission harness 28 are conductively connected. The other end of the signal transmission harness 28 is connected to the unlocking warning switch 7, and the other end of the wiring harness 27 is connected to the vehicle body for power supply, so that the signal transmission harness 28 sends an electrical signal to the alarm 8. At this time, the unlocking handle 6 has both an unlocking function and an alarm function.

[0041] The operation process of the emergency window of the present invention is as follows: when the emergency window is in the closed state, the lock pin is located in the bayonet 12 and forms a locking position for the lock plate 10. When the door cannot be opened due to an accident, the passenger first pulls the handle, and the pull wire 13 transmits the power of the handle rotation to the ratchet plate 11. The ratchet plate 11 rotates to avoid the lock plate 10. At this time, the inner window frame 1 and the outer window frame 2 are unlocked, and then an outward thrust is applied to the inner window frame 1, and the inner window frame 1 is opened outward. At the same time, the lock plate 10 is driven by the lock pin to rotate to the bayonet 12 and separate from the lock pin. The inner window frame 1 is turned outward to a certain angle. The ratchet plate 11 avoids the lock plate 10 and contacts and cooperates with the unlocking warning switch 7. The unlocking warning switch 7 is closed and the unlocking warning switch 7 is closed. The signal transmission harness 28 connected to the indicator switch 7 sends an electrical signal to the alarm 8 on the unlocking handle 6, and the alarm 8 sounds an alarm, so that the passengers can know that the emergency window has been opened at the first time. Then the passengers apply an outward pushing force to the inner window frame 1, and the inner window frame 1 will be completely flipped open with the help of the hidden air support structure 18, allowing passengers to escape. If the emergency window needs to be closed, place your hand on the semi-hidden handle 25 and apply an inward pulling force to it, so that the inner window frame 1 is flipped and reset to the bayonet 12 to contact the lock pin again, and is driven to reset by the lock pin. At this time, the pull wire 13 drives the ratchet plate 11 to reset, and the ratchet plate 11 again supports the lock plate 10, forming a lock between the inner window frame 1 and the outer window frame 2.

[0042] The vehicle of the present invention is implemented as follows:

[0043] The vehicle includes an emergency window, which is installed on the vehicle body. The emergency window described here is consistent with the above-mentioned emergency window structure and will not be repeated. Installing the emergency window on the vehicle body can avoid false alarms of the alarm device 8, and the unlocking speed between the inner window frame 1 and the outer window frame 2 is faster, and there is no jamming during the unlocking process, so that passengers can escape quickly. Installing the emergency window on the vehicle can effectively increase the possibility of escape of passengers.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall also be included in the scope of protection of the present invention.
