Description

Technical Field

[0001] The present application relates to the technical field of vehicle window assemblies, and in particular to a vehicle window assembly and a driving safety assistance system. Background Art

[0002] Trams have become an important means of transportation due to their excellent carrying capacity. However, since trams are usually composed of multiple carriages, there will be a large blind spot on the side of the vehicle for the driver. Currently, trams have integrated cameras, but most of them are rearview mirror cameras. For drivers, the distance between the front and the back is far, so the blind spot still exists, and the driver still needs to stare at the monitoring screen at all times to judge the danger, resulting in limited help for driving safety. Summary of the invention

[0003] The embodiments of the present application provide a vehicle window assembly and a driving safety assistance system to solve the current problems.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In a first aspect, a vehicle window assembly is provided, comprising a window frame, an outer layer of glass, an inner layer of glass, a spacer, a camera, and a first alarm. At least a portion of the outer layer of glass is covered in the window frame. At least a portion of the inner layer of glass is covered in the window frame and is opposite to the outer layer of glass, and there is a containing space between the window frame, the outer layer of glass, and the inner layer of glass. The spacer is arranged between the outer layer of glass and the inner layer of glass and is located in the containing space. The camera and the first alarm are respectively arranged in the containing space.

[0006] The second aspect provides a driving safety assistance system, including a window assembly, a display, and a second alarm. The window assembly is arranged on the body of the vehicle, and the camera captures the exterior of the vehicle and generates a first image signal. The host is arranged on the vehicle, and the host is electrically connected to the camera and the first alarm. The host receives and processes the first image signal from the window assembly. The display is arranged in the cab of the vehicle and is electrically connected to the host. The host transmits an image signal to the display, and the display displays the first image according to the first image signal. The second alarm is arranged in the cab of the vehicle and is electrically connected to the host. Among them, when the host determines that the vehicle is in a dangerous state according to the first image signal, the host generates an alarm signal and transmits it to the second alarm, and the second alarm warns according to the alarm signal; the host also generates a second image signal and transmits the second image signal to the display, and the display displays a second image according to the second image signal, and the second image shows the area where the danger occurs.

[0007] In the embodiment of the present application, the window assembly of the present application uses a camera to capture the situation outside the vehicle to provide the driver with a first image. When a situation occurs, the driving safety assistance system sends an alarm signal through the host, causing the first alarm and the second alarm to issue a reminder. At the same time, the display will switch to the second image to display the dangerous area. Therefore, driving safety can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0015] See also Figure 1, which is a schematic diagram of a vehicle window assembly of the first embodiment of the present application. As shown in the figure, the vehicle window assembly 1 of the present embodiment includes: a window frame 10, an outer layer of glass 11, an inner layer of glass 12, a spacer bar 13, a camera 14 and a first alarm 15. The window frame 10 is arranged on the vehicle, and at least a portion of the outer layer of glass 11 is covered in the window frame 10. At least a portion of the inner layer of glass 12 is covered in the window frame 10 and arranged relative to the outer layer of glass 11. There is an accommodation space between the window frame 10, the outer layer of glass 11 and the inner layer of glass 12, and the camera 14 and the first alarm 15 are arranged in the accommodation space. The spacer bar 13 is arranged between the outer layer of glass 11 and the inner layer of glass 12 and is located in the accommodation space. The camera 14 captures the image of the outside of the vehicle into an image signal, and the driver judges the scene outside the vehicle through the image signal to reduce the blind spot during driving and improve driving safety. At the same time, the first alarm 15 can also be used to warn road users or passengers in the vehicle when danger occurs.

[0016] In this embodiment, the outer glass 11 can be a tempered glass with high light transmittance, which can provide passengers with a good field of vision and reduce scratches caused by the collision between dust and glass. The inner glass 12 can be the same tempered glass as the outer glass 11, or it can be a dimming glass with the function of adjusting light to reduce the strong light entering the eyes of passengers and improve the riding comfort. In addition, the spacer 13 is used to separate the outer glass 11 and the inner glass 12, and the joint between the spacer 13 and the glass is filled with polymer adhesive to improve the adhesion and prevent dust and moisture from invading the accommodation space, thereby preventing the camera 14 and the first alarm 15 located in the accommodation space from being damaged.

[0017] The camera 14 is a miniature camera tool, but in some embodiments, the camera can be a larger zoom lens to provide high-definition images from a farther distance. Alternatively, the camera 14 can also have an infrared camera function to provide the driver with a good image when driving at night to avoid accidents caused by poor light.

[0018] The first alarm 15 can be a high-brightness light bulb, which can remind passengers on the bus and passers-by to take evasive action by emitting flashing light. Furthermore, the first alarm 15 can emit light of different colors to indicate different levels of danger. For example, when an object approaches but has not yet entered the danger zone, only a yellow light is emitted, while a red light is emitted when the object enters the danger zone. In addition, the first alarm 15 can also be a buzzer, which can remind passengers on the bus and passers-by to take evasive action by sound. In some embodiments, the first alarm 15 can also use the above-mentioned light and sound at the same time for reminder.

[0019] See also Figure 2, which is a schematic diagram of a vehicle window assembly of the second embodiment of the present application. As shown in the figure, the vehicle window assembly 1a of this embodiment further includes a signal adapter board 16 compared with the vehicle 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 in practice digital signals are easier to analyze and process than analog signals, in this embodiment, the image signal is converted from an analog signal to a digital signal through the signal adapter board 16 to facilitate subsequent processing. In addition, the remaining components are the same as those of the first embodiment, so they are not repeated here.

[0020] See also Figure 3 , which is a schematic diagram of a driving safety assistance system of the third embodiment of the present application. As shown in the figure, 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 this embodiment uses the window assembly 1a of the second embodiment, which is arranged on the vehicle, and the camera 14 captures the scene outside the vehicle and generates a first image signal. The host 30 is arranged on the vehicle and is electrically connected to the camera 14 and the first alarm 15. The host 30 is used to receive and process the first image signal from the window assembly 1a. The display 41 is arranged in the cab of the vehicle, and displays the first image according to the first image signal. The second alarm 42 is arranged in the cab and is electrically connected to the host 30. Specifically, when the host 30 determines that the vehicle is in a dangerous state based on the first image signal, an alarm signal will be generated, and the second alarm 42 will warn according to the alarm signal; in addition, the host 30 also generates a second image signal and transmits the second image signal to the display 41. The display 42 will display a second image based on the second image signal. The second image will show the dangerous area, so that the driver can quickly know the situation and respond.

[0021] In this embodiment, the host 30 is a computer with a computing function, which can not only judge the image, but also process the first image signal from the camera 14. For example, under normal circumstances, the host 30 directly sends the first image signal to the display 41 to provide a visual image of the driver's blind spot; in dangerous situations, the host 30 also provides a second image signal to the display 41, so that the display 41 displays the second image. The second image can be an image that is specially marked or enlarged after being processed by the host 30. For example, the outline of pedestrians or moving objects is colored by the host 30, so that the driver can see the problem point more quickly.

[0022] Please also read Figure 4, which is a block diagram of the driving safety assistance system of the third embodiment of the present application. As shown in the figure, the host 30 also includes a processor 301, a switch 302 and a power supply 303, wherein the processor 301 is electrically connected to the power supply 303 and the switch 302, and the switch 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. In addition, the switch 302 is also electrically connected to the brake device 43 of the vehicle. The camera 14 transmits the first image signal to the host 30 through the signal adapter board 16. After the processor 301 judges based on the first image signal, it sends an alarm signal to the first alarm 15 and the second alarm 42 through the switch 302, and makes the display 41 display the second image signal, and the processor 301 also controls the brake device 43 of the vehicle to start. Furthermore, when the brake device 43 is started, the processor 301 will stop sending the alarm signal. Through the above configuration, the host can automatically brake in dangerous situations to avoid accidents caused by the driver's slow reaction.

[0023] In an embodiment, the processor 301 may be a microprocessor or a chipset obtained by integration. The processor 301 may also pre-store a safety distance, and an upper limit and a lower limit may be set respectively. For example, the processor 301 determines the distance between the vehicle and other vehicles based on the first image signal. When the distance between the vehicles is less than the upper limit (for example, less than 3 meters), the processor 301 determines that this situation is a dangerous state and sends an alarm signal through the switch 302. When the distance between the vehicles is less than the lower limit (for example, less than 1 meter) and the brake device 43 is not activated by the driver, the processor 301 actively controls the brake device 43 to start to stop the vehicle. In other embodiments, the upper limit and the lower limit may be set for different types of conditions. For example, when the vehicle is traveling at high speed, the upper limit and the lower limit of the first group may be set, and when the vehicle is traveling at low speed, the upper limit and the lower limit of the second group may be set, and the upper limit and the lower limit of the first group are higher than the upper limit and the lower limit of the second group. In addition, when a dangerous situation occurs (that is, another vehicle appears next to the vehicle and is within the distance between the upper limit and the lower limit set by the host 30), if the driver activates the braking device 43, the braking device 43 will send an actuation signal to the host 30, and the host 30 will generate a shutdown signal based on the actuation signal to stop the first alarm 14 and the second alarm 42 without the need for the driver to manually shut down the warning.

[0024] In addition, the power supply 303 is mainly used as the power source of the processor 301 and the switch 302. It can be a large lithium battery, or connected to the train's power system and charged by the power generated by the vehicle. The switch 302 is provided with multiple connection ports to send the instructions of the processor 301 to various components.

[0025] In addition, the display 41 is arranged in the cab, and it can be a liquid crystal display or a display with a touch function. In some embodiments, the number of the display 41 can also be multiple, so that the driver can monitor multiple positions at the same time to reduce the probability of accidents.

[0026] The second alarm 42 may be disposed beside the display 41 , and the second alarm 42 may be the same as the first alarm 15 to provide light and / or sound prompts to alert the driver to the accident.

[0027] See also Figure 5 , which is a schematic diagram of a vehicle according to the fourth embodiment of the present application. As shown in the figure, there may be multiple window assemblies 1a, 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 range (such as area A in the figure), and the camera range of each camera 14 partially overlaps with the camera range of the adjacent camera 14 (such as area B in the figure). In other words, by overlapping the camera ranges, gaps between two adjacent camera ranges are avoided, which may lead to safety omissions. In other embodiments, the processor 30 can also splice the images through the overlapping parts to form a continuous and large-scale image, so that the driver can see the surrounding situation more clearly.

[0028] In summary, the window assembly of the present application uses a camera to capture the situation outside the vehicle to provide the driver with a first image. When a situation occurs, the driving safety assistance system sends an alarm signal through the host, causing the first alarm and the second alarm to issue a reminder. At the same time, the display will switch to the second image to display the dangerous area. Therefore, driving safety can be effectively improved.

[0029] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0030] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
