As shown in the drawings, the window assembly 1 of the present embodiment includes: the window comprises a window frame 10, an outer layer of glass 11, an inner layer of glass 12, a spacing bar 13, a camera 14 and a first alarm 15. The window frame 10 is provided on a vehicle, and at least a portion of the outer glass 11 is wrapped in the window frame 10. At least a portion of the inner glass 12 is wrapped in the window frame 10 and disposed opposite the outer glass 11. An accommodating space is formed among the window frame 10, the outer layer glass 11 and the inner layer glass 12, and the camera 14 and the first alarm 15 are arranged in the accommodating space. The spacing bar 13 is arranged between the outer layer glass 11 and the inner layer glass 12 and is positioned in the accommodating space. The camera 14 shoots images outside the vehicle into image signals, and the driving judges the images outside the vehicle through the image signals so as to reduce blind areas during driving, improve driving safety, and warn passers-by or passengers in the vehicle through the first alarm 15 when danger occurs.

In the present embodiment, the outer glass 11 may be a tempered glass having high transmittance, which can provide a good view for passengers while reducing scratches caused by collision between dust and glass. The inner layer glass 12 may be a strengthened glass similar to the outer layer glass 11, or may be a light-adjusting glass with a light-adjusting function, so as to reduce the strong light entering the eyes of passengers, and improve the riding comfort. In addition, the spacing bar 13 is used for separating the outer layer glass 11 from the inner layer glass 12, and the polymer adhesive is filled at the joint of the spacing bar 13 and the glass, so that the adhesion can be improved, dust and moisture can be prevented from entering the accommodating space, and the camera 14 and the first alarm 15 in the accommodating space can be prevented from being damaged.

The camera 14 is a miniature camera tool, but in some embodiments the camera may be a zoom lens of a larger size to provide a higher resolution image at a greater distance. Alternatively, the camera 14 may have an infrared camera function, and provide a good image of the driver when driving at night, thereby avoiding an accident caused by poor light.

The first alarm 15 may be a high-brightness bulb that emits a flashing light to remind passengers in the vehicle and pedestrians to avoid the vehicle. Still further, the first alarm 15 can emit different colors of light to indicate different levels of danger. For example, when an object is close to but not entering a dangerous area, only yellow light is emitted, and when the object enters the dangerous area, red light is emitted. In addition, the first alarm 15 may be a buzzer to remind passengers and passers-by to evade by sound. In some embodiments, the first alarm 15 may also use the lights and sounds mentioned above to provide a reminder.

As shown in the figure, the window assembly 1a of the present embodiment further includes a signal adapter board 16, compared with the window assembly 1, and the signal adapter board 16 is electrically connected to the camera 14. Since the image signal captured by the camera 14 is an analog signal, but the digital signal is easier to analyze and process than the analog signal, the image signal is converted from the analog signal to the digital signal by the signal adapter board 16 in this embodiment, so as to facilitate the subsequent processing. Otherwise, the remaining elements are the same as those of the first embodiment, and thus are not described again.

Please refer to fig. 3, which is a schematic diagram of a driving safety assistance system according to a third embodiment of the present application. As shown, the driving safety assistance system 2 includes a window assembly 1a, a host 30, a display 41, and a second alarm 42. The window glass assembly 2 of the present embodiment uses the window glass assembly 1a of the second embodiment, which is disposed on a vehicle, and the camera 14 photographs a scene outside the vehicle and generates a first image signal. The host 30 is disposed on the vehicle and electrically connected to the camera 14 and the first alarm 15, and the host 30 is configured to receive and process the first image signal from the window assembly 1 a. The display 41 is provided in the cab of the vehicle, and displays a first image according to the first image signal. The second alarm 42 is disposed in the cab and electrically connected to the main unit 30. Specifically, when the host 30 determines that the vehicle is in a dangerous state according to the first image signal, an alarm signal is generated, and the second alarm 42 warns according to the alarm signal; in addition, the host 30 generates a second image signal and transmits the second image signal to the display 41, and the display 42 displays a second image according to the second image signal, and the second image displays a dangerous area, so that the driver can quickly know the situation to respond.

In the present embodiment, the host computer 30 is a computer having an arithmetic function, and can perform data processing on the first video signal from the camera 14 in addition to the determination of the video. For example, in a normal situation, the host 30 directly transmits the first image signal to the display 41 to provide a view image of a driving blind area; in a dangerous situation, the host 30 may further provide a second image signal to the display 41 to make the display 41 display a second image, where the second image may be an image processed by the host 30 and specially marked or enlarged in a dangerous area, for example, the host 30 colors the contour of a pedestrian or a moving object to make the driver more quickly see a problem point.

Please refer to fig. 4, which is a block diagram of a driving safety assistance system according to a third embodiment of the present application. As shown in the figure, the host 30 further includes a processor 301, an exchanger 302 and a power supply 303, wherein the processor 301 is electrically connected to the power supply 303 and the exchanger 302, the exchanger 302 is electrically connected to the signal adapter board 16, the power supply 303, the display 41, the first alarm 15 and the second alarm 42, and the exchanger 302 is also electrically connected to the braking device 43 of the vehicle. The camera 14 transmits the first image signal to the host 30 through the signal adapting board 16, the processor 301 sends an alarm signal to the first alarm 15 and the second alarm 42 through the switch 302 after determining according to the first image signal, and enables the display 41 to display the second image signal, and the processor 301 controls the braking device 43 of the vehicle to be activated, and further, when the braking device 43 is activated, the processor 301 stops sending the alarm signal. Through the configuration, the host can automatically brake under the dangerous condition so as to avoid the regret phenomenon caused by the untimely reaction of driving.

In an embodiment, the processor 301 may be a microprocessor or a chipset obtained by integration. The processor 301 may also store the safety distance in advance, and may set an upper limit value and a lower limit value, respectively. For example, the processor 301 determines the distance between the carried vehicle and another vehicle according to the first image signal, when the distance between the vehicles is smaller than an upper limit value (e.g., smaller than 3 meters), the processor 301 determines that the situation is a dangerous state, and sends an alarm signal through the switch 302, and when the distance between the vehicles is smaller than a lower limit value (e.g., smaller than 1 meter) and the braking device 43 is not activated by the driver, the processor 301 actively controls the braking device 43 to be activated to stop the vehicle. In other embodiments, the upper limit value and the lower limit value may be set for different types of conditions, for example, when the vehicle travels at a high speed, the upper limit value and the lower limit value of the first group may be set, and when the vehicle travels at a low speed, the upper limit value and the lower limit value of the second group may be set, and the upper limit value and the lower limit value of the first group are higher than those of the second group. In addition, when a dangerous condition occurs (i.e. other vehicles are present beside the vehicle and are located in the distance between the upper limit value and the lower limit value set by the main unit 30), if the driving starts the braking device 43, the braking device 43 will send an actuating signal to the main unit 30, and the main unit 30 generates a closing signal according to the actuating signal to stop the first alarm 14 and the second alarm 42 without the need of driving a manual closing alarm.

The power supply 303 is mainly used as a power source for the processor 301 and the switch 302, and may be a large lithium battery, or may be connected to a train power system and charged by power generated by a vehicle. The switch 302 is provided with a plurality of ports for sending instructions from the processor 301 to various components.

In addition, a display 41, which may be a liquid crystal display or a display having a touch function, is provided in the cab. In some embodiments, the number of displays 41 may be multiple, so that the driver can monitor multiple locations simultaneously to reduce the chance of accidents.

The second alarm 42 may be located next to the display 41 and the second alarm 42 may be the same as the first alarm 15 to provide a light and/or sound indication to the driver to notice the accident.

As shown in the figure, the number of the window assemblies 1a may be multiple, and multiple window assemblies 1a are arranged side by side on the vehicle body, the camera 14 of each window assembly 1a has a camera shooting range (as an area a in the figure), and the camera shooting range of each camera 14 and the camera shooting range of the adjacent camera 14 partially overlap with each other (as an area B in the figure). That is, the imaging ranges overlap with each other, so that a gap between two adjacent imaging ranges is avoided, which leads to security omission. In other embodiments, the processor 30 can also stitch the images into a continuous and wide-range image through the overlapped portions, so that the driver can see the surrounding situation more clearly.

To sum up, the outside condition of vehicle is shot through the camera to the door window assembly of this application to offer and drive and watch first image, when taking place the situation, driving safety auxiliary system sends alarm signal through the host computer, lets first alarm and second alarm send the warning, and simultaneously, the display will be switched into the second image and take place dangerous region with the demonstration. Therefore, the driving safety can be effectively improved.
