For example, when a vehicle encounters an emergency such as a car accident, the vehicle may automatically lose power and be unable to open the door to escape. In this case, breaking the glass becomes the main means for people inside the vehicle to escape.

[0021] In one embodiment, the detection unit includes a first sensor for detecting and identifying ice on the glass body to obtain a second detection signal. The main control unit receives the second detection signal and drives the first vibrator to vibrate at a second vibration frequency and a second amplitude. The first vibrator is used to drive the glass body to vibrate along the thickness direction to separate the glass body from the ice.

[0032] In related technologies, with the popularization of new energy vehicles, the application of hidden door handles and electric locks is becoming increasingly widespread. However, this also brings safety issues. For example, when a vehicle encounters an accident or a battery fire, the vehicle may automatically shut off, making it impossible to open the doors for escape. In such cases, breaking the car window becomes the primary means of escape for occupants. Typically, people use hammers or other hard objects to break the window for escape, but this method is easily limited by space, difficult to implement in crisis situations, and time-consuming, thus affecting the vehicle's safety in emergency situations.

Figure 2 for Figure 1 The diagram shows a partial structural diagram of the glass assembly of the vehicle shown. Figure 3 for Figure 2 The diagram shown is a simplified structural representation of the glass assembly.

[0047] This application provides a means of transportation 1000. The means of transportation 1000 can be a vehicle, ship, submarine, airplane, etc. The means of transportation 1000 in this application embodiment is as follows: Figure 1 The vehicle shown is used as an example for illustration.

[0048] The vehicle can be, but is not limited to, sedans, multi-purpose vehicles (MPVs), sport / suburban utility vehicles (SUVs), off-road vehicles (ORVs), pickup trucks, vans, buses, and trucks. In this specific embodiment, a sedan is used as an example for illustration.

[0049] For ease of description, the embodiments of this application define... Figure 1 The width of the vehicle 1000 shown is the X-axis, the length is the Y-axis, and the height is the Z-axis. The X-axis, Y-axis, and Z-axis are all perpendicular to each other.

[0050] The directional terms such as "top," "bottom," "left," "right," "front," and "back" used in this application are based on the appendix to the specification. Figure 1 The orientation of the vehicle 1000 is described with the forward direction along the length of the vehicle 1000 as the positive direction of the Y-axis, the direction from left to right along the width of the vehicle 1000 as the positive direction of the X-axis, and the direction away from the ground along the height of the vehicle 1000 as the positive direction of the Z-axis.

[0051] The vehicle 1000 includes a body 200, a glass assembly 100, and a power supply (not shown). Both the glass assembly 100 and the power supply are mounted on the body 200. The power supply provides power to the vehicle 1000. The glass assembly 100 includes a glass body 10 and a window-breaking device 20. The glass body 10 provides lighting, ventilation, and visibility for the occupants inside the vehicle 1000. The window-breaking device 20 is connected to the glass body 10. The window-breaking device 20 is electrically connected to the power supply.

[0052] The glass body 10 can be the windshield, rear windshield, side window, corner window, sunroof, etc. of the vehicle 1000. Correspondingly, the glass assembly 100 can be the windshield assembly, rear windshield assembly, side window assembly, corner window assembly, sunroof assembly, etc. of the vehicle 1000. In this embodiment, the glass body 10 is described and illustrated using the side window glass of the vehicle 1000 as an example, and correspondingly, the glass assembly 100 is described and illustrated using the side window assembly of the vehicle 1000 as an example.

[0053] The main body 200 includes a supporting body 201 and a door 202. The supporting body 201 has a doorway 2011. The doorway 2011 connects the inner and outer sides of the main body 200. The door 202 is connected to the edge of the doorway 2011 and can rotate relative to the supporting body 201. The door 202 can open or close the doorway 2011. When the doorway 202 is open, the doorway 2011 is exposed, and occupants can enter or leave the supporting body 201 through the doorway 2011. In this embodiment, the vehicle 1000 is a vehicle, the main body 200 can be understood as the vehicle body, the supporting body 201 can be understood as the vehicle body, and the door 202 can be understood as a vehicle door.

[0054] The body 200 also has a window 2021. The window 2021 connects the inner and outer sides of the body 200. The window 2021 has an outer edge 2022. In this embodiment, the window 2021 is disposed on the door 202, and the window 2021 penetrates both surfaces of the door 202 in the thickness direction. The outer edge 2022 of the window 2021 includes a bottom edge 2023. Along the Z-axis direction, the edge of the outer edge 2022 of the window 2021 away from the top of the door 202 is the bottom edge 2023. It should be noted that, for ease of illustration, Figure 2 The dashed line in the figure represents the bottom edge 2023 of window 2021. In other embodiments, window 2021 may also be disposed on the supporting body 201.

[0055] A glass body 10 is mounted on a window 2021. The glass body 10 is movable relative to a door 202 within the window 2021 along the Z-axis, meaning it can be raised and lowered relative to the door 2021 to open or close the window 2021. A portion of the glass body 10 is obscured by the outer edge 2022 of the window 2021. Exemplarily, a portion of the glass body 10 is obscured by the bottom edge 2023 of the window 2021. A window-breaking device 20 is connected to the glass body 10, and is also obscured by the bottom edge 2023 of the window 2021. It is understood that when the glass body 10 closes or opens the window 2021, a portion of the glass body 10 is always obscured by the bottom edge 2023 of the window 2021. The window-breaking device 20 can be connected to the portion of the glass body 10 obscured by the bottom edge 2023 of the window 2021, and can be connected to any position of that portion of the glass body 10.

[0056] In this embodiment, the window breaking device 20 is always located below the bottom edge 2023 of the window 2021 and is blocked by the bottom edge 2023 of the window 2021 to prevent the window breaking device 20 from being exposed to the window 2021 and thus ensuring the aesthetics of the glass body 10 and improving the appearance of the vehicle 1000.

[0057] In this embodiment, as Figure 3 As shown, the window breaking device 20 is mounted on the side of the glass body 10 facing the interior of the vehicle 1000. In other embodiments, the window breaking device 20 may be mounted on the side of the glass body 10 facing the exterior of the vehicle 1000. In other embodiments, the window breaking device 20 may be mounted on the door 202 and can be indirectly connected to the glass body 10 via a transmission mechanism (such as a transmission rod).

[0058] In this embodiment, the vehicle 1000 also includes a safety module (not shown). The safety module is installed in the main body 200 and electrically connected to an external power source. The safety module may include, but is not limited to, an airbag control module, an electronic parking brake control module, a battery management module, or other electronic control modules responsible for monitoring, managing, and executing the safety functions of the vehicle 1000. The safety module can be triggered and activated when the vehicle 1000 encounters an emergency (such as a collision).

[0059] The safety module is also electrically connected to the window-breaking device 20. When the vehicle 1000 encounters an emergency, the safety module is triggered, and the window-breaking device 20 is activated and vibrates upon detecting the activation of the safety module. The vibration of the window-breaking device 20 causes the glass body 10 to vibrate, thereby automatically and quickly breaking the glass body 10. This facilitates the rapid escape of occupants inside the vehicle 1000 through the window 2021, preventing the door 202 from being unable to be opened directly or quickly in such an emergency, thus ensuring that occupants can escape the vehicle 1000 quickly through the door 2011. For example, the safety module includes an airbag control module. When the vehicle 1000 collides, the airbag control module is triggered, and the window-breaking device 20 is also quickly activated upon detecting the activation of the airbag control module, thus breaking the window.

[0060] In this embodiment, the thickness of the glass body 10 is sufficient not only to ensure rapid breakage by the window-breaking device 20 in emergency situations, but also to meet the structural strength requirements of the glass body 10 in daily use scenarios, thus avoiding the risk of breakage during daily use and ensuring the safety of the glass body 10 in daily use. For example, the thickness of the glass body 10 can be greater than or equal to 1 mm and less than or equal to 6 mm.

[0061] Please continue to refer to the following: Figure 2 and Figure 3 .

[0062] The window-breaking device 20 includes a first vibrator 21, a main control unit 22, and a detection unit 23. The first vibrator 21, the main control unit 22, and the detection unit 23 are all electrically connected to a power source. The detection unit 23 is electrically connected to a safety module, and is used to detect and identify the opening of the safety module and acquire a first detection signal. The main control unit 22 is electrically connected to the detection unit 23 and the first vibrator 21. The main control unit 22 receives the first detection signal from the detection unit 23 and drives the first vibrator 21 to vibrate. Furthermore, based on the received first detection signal, the main control unit 22 can adjust the vibration frequency and amplitude of the first vibrator 21, causing the first vibrator 21 to vibrate at a first vibration frequency and a first amplitude.

[0063] The first vibrator 21 is connected to the glass body 10. The vibration of the first vibrator 21 can control and drive the glass body 10 to generate high-frequency vibration. The high-frequency vibration is defined as vibration with a frequency greater than 20 kHz. The vibration direction of the first vibrator 21 is set at an angle to the thickness direction of the glass body 10, forming a first angle. That is, the vibration direction of the first vibrator 21 forms an angle with the largest surface of the glass body 10 (i.e., the surface in the thickness direction of the glass body 10). The vibration of the first vibrator 21 causes the glass body 10 to vibrate in the thickness direction of the glass body 10. The first angle can be determined based on the installation angle of the first vibrator 21 relative to the thickness direction of the glass body 10. The first angle is greater than or equal to 0° and less than 45°. Preferably, the first angle is 0°, and the vibration direction of the first vibrator 21 is parallel to the thickness direction of the glass body 10.

[0064] In this embodiment, the first vibrator 21 can be an ultrasonic transducer. An ultrasonic transducer is a device that converts electrical energy into mechanical waves. It is generally made of piezoelectric ceramic. When a pulse voltage of a corresponding frequency is applied to it, the internal piezoelectric crystal drives the vibrating plate to vibrate, emitting ultrasonic waves. The ultrasonic waves are sound waves with a frequency higher than 20kHz, which can drive the glass body 10 to vibrate.

[0065] In this embodiment, when the vehicle 1000 encounters an emergency, the safety module is triggered and activated. The detection unit 23 detects and identifies that the safety module is activated and acquires a first detection signal. The main control unit 22 receives the first detection signal from the detection unit 23 and controls the power supply to energize the first vibrator 21, driving the first vibrator 21 to vibrate at a first vibration frequency and a first amplitude. The first vibrator 21 is connected to the glass body 10. The vibration of the first vibrator 21 causes the glass body 10 to vibrate, and causes the glass body 10 to vibrate along the thickness direction of the glass body 10. Moreover, the main control unit 22 can adjust the first vibration frequency of the first vibrator 21 to match the natural frequency of the glass body 10 according to the received first detection signal, so that the first vibrator 21 and the glass body 10 resonate, and adjust the first amplitude of the first vibrator 21 to make the amplitude of the glass body 10 exceed the limit that the material of the glass body 10 can withstand, causing the glass body 10 to break, thus realizing the window breaking function of the window breaking device 20.

[0066] In one embodiment, the detection unit 23 includes a first sensor. The first sensor is capable of detecting and identifying ice layers present on the glass body 10 and acquiring a second detection signal. The second detection signal can be received by the main control unit 22, which then controls the power supply to energize the first vibrator 21. The first sensor can be one or a combination of optical sensors, cameras, temperature sensors, etc.

[0067] In this embodiment, when the glass body 10 is frozen by ice, the first sensor detects and identifies the ice layer on the glass body 10 and acquires a second detection signal. The main control unit 22 receives the second detection signal and controls the power supply to energize the first vibrator 21, driving the first vibrator 21 to vibrate at a second vibration frequency and a second amplitude. The vibration of the first vibrator 21 causes the glass body 10 to vibrate along the thickness direction of the glass body 10 and separate from the ice layer, realizing the de-icing function of the window breaking device 20 and preventing the glass body 10 from being frozen by ice and unable to rise or fall.

[0068] In this embodiment, the vibration frequency of the first vibrator 21 is greater than or equal to 30kHz and less than or equal to 400kHz, and the amplitude of the first vibrator 21 is greater than or equal to 10μm and less than 100μm. When the first vibration frequency of the first vibrator 21 is greater than or equal to 30kHz and less than 100kHz, and the first amplitude is greater than 50μm and less than or equal to 100μm, the first vibrator 21 vibrates at the first vibration frequency and the first amplitude, which can achieve window breaking; preferably, the first vibration frequency of the first vibrator 21 is greater than or equal to 30kHz and less than or equal to 60kHz.

[0069] When the second vibration frequency of the first vibrator 21 is greater than or equal to 100 kHz and less than or equal to 400 kHz, and the second amplitude is greater than or equal to 10 μm and less than or equal to 50 μm, the first vibrator 21 can achieve de-icing when vibrating at the second vibration frequency and the second amplitude; preferably, the second vibration frequency of the first vibrator 21 is greater than or equal to 200 kHz and less than or equal to 400 kHz.

[0070] It is understood that the vibration frequency and amplitude of the first vibrator 21 in this embodiment are adjustable. When the first vibrator 21 has a lower frequency and a larger amplitude, it can automatically and quickly break the window, which is beneficial for passengers to escape quickly through the window 2021 in an emergency. When the first vibrator 21 has a higher frequency and a smaller amplitude, it can perform de-icing, which not only prevents the glass body 10 from being frozen by ice and unable to rise or fall, but also restores the visibility of the glass body 10 after de-icing, preventing the ice from affecting the vision of the passengers inside the vehicle. Moreover, the adjustable vibration frequency and amplitude of the first vibrator 21 meet the breaking or de-icing needs of glass bodies 10 of different specifications, expands the applicability of the window breaking device 20, and achieves the lowest possible development cost.

[0071] In one embodiment, the window-breaking device 20 further includes a second vibrator (not shown). The second vibrator is electrically connected to a power source and to a main control unit 22. The second vibrator can be driven by the main control unit 22 to generate vibration, and the vibration frequency and amplitude of the second vibrator are adjusted by the main control unit 22. The second vibrator is connected to the glass body 10. The vibration of the second vibrator can control and drive the window glass body 10 to generate high-frequency vibration. The vibration direction of the second vibrator is set at an angle to the direction parallel to the maximum surface of the glass body 10, forming a second angle. That is, a second angle is formed between the vibration direction of the second vibrator and the maximum surface of the glass body 10. The vibration of the second vibrator can cause the glass body 10 to vibrate along the direction parallel to the maximum surface of the glass body 10. The second angle can be determined according to the installation angle of the second vibrator relative to the maximum surface of the glass body 10. The second angle is greater than or equal to 0° and less than or equal to 45°.

[0072] The structure of the second vibrator can be the same as or different from that of the first vibrator 21. In this embodiment, the second vibrator can be an ultrasonic transducer.

[0073] The detection unit 23 also includes a second sensor. The second sensor can detect and identify water droplets or dust and other debris on the glass body 10, and can acquire a third detection signal. The third detection signal can be received by the main control unit 22, which then controls the power supply to energize the second vibrator. The second sensor can be one or a combination of optical sensors, cameras, rain sensors, etc.

[0074] In this embodiment, when water droplets or dust or other debris are present on the glass body 10, the second sensor detects and identifies the presence of water droplets or dust or other debris on the glass body 10 and acquires a third detection signal. The main control unit 22 receives the third detection signal and controls the power supply to energize the second vibrator, thereby driving the second vibrator to vibrate at a specific frequency and amplitude. The vibration of the second vibrator causes the glass body 10 to vibrate along a direction parallel to the maximum surface area of ​​the glass body 10. The vibration of the glass body 10 generates a shear force parallel to the surface of the water droplets or dust or other debris on its surface. Driven by the shear force, the water droplets or dust on the glass body 10 can slide off the glass surface, thus realizing the functions of water removal and dust removal of the window breaking device 20.

[0075] In this embodiment, the vibration frequency of the second vibrator is greater than or equal to 30kHz and less than or equal to 400kHz, and the amplitude of the second vibrator is greater than or equal to 10μm and less than 100μm. When the vibration frequency of the second vibrator is greater than or equal to 100kHz and less than or equal to 400kHz, and the amplitude is greater than or equal to 10μm and less than or equal to 50μm, the functions of water removal and dust removal can be achieved; preferably, the vibration frequency of the second vibrator is greater than or equal to 200kHz and less than or equal to 400kHz.

[0076] It is understood that the vibration frequency and amplitude of the second vibrator in this embodiment are adjustable. When the second vibrator has a higher frequency and a smaller amplitude, it can achieve the functions of water removal and dust removal, ensuring the cleanliness and visibility of the glass body 10 and preventing water droplets and dust from affecting the vision of the occupants inside the vehicle. Moreover, the adjustable vibration frequency and amplitude of the second vibrator meet the needs of water removal and dust removal for glass bodies 10 of different specifications, expanding the applicability of the window breaking device 20 and minimizing development costs.

[0077] It should be noted that the number and position of the first vibrator 21 and the second vibrator can be set according to the needs of the glass assembly 100 for de-icing, window breaking, water removal, and dust removal. When the window breaking device 20 of the glass assembly 100 needs to break a window, the window breaking device 20 includes at least one first vibrator 21. When the window breaking device 20 of the glass assembly 100 needs to break a window and de-ic, the window breaking device 20 includes at least one first vibrator 21, and the detection unit 23 includes at least one first sensor. When the window breaking device 20 of the glass assembly 100 needs to break a window, remove water, and remove dust, the window breaking device 20 includes at least one first vibrator 21 and at least one second vibrator, and the detection unit 23 includes at least one second sensor. When the window breaking device 20 of the glass assembly 100 needs to perform window breaking, de-icing, water removal, and dust removal functions simultaneously, the window breaking device 20 includes at least one first vibrator 21 and at least one second vibrator, and the detection unit 23 includes at least one first sensor and at least one second sensor.

[0078] In this embodiment, there are multiple ways to connect the first vibrator 21 and the second vibrator to the glass body 10, and the first vibrator 21 and the second vibrator can be connected to the glass body 10 in the same or different ways.

[0079] For ease of description, the following description assumes that the first vibrator 21 is connected to the glass body 10. The second vibrator may also be connected to the glass body 10 according to the connection method described below, which will not be repeated here.

[0080] For the first connection method, please refer to [link / reference]. Figure 4 , Figure 4 for Figure 2 A schematic cross-sectional view of a portion of the structure of the first embodiment of the glass assembly shown.

[0081] In this embodiment, the glass body 10 includes an outer surface 11 and an inner surface 12. The outer surface 11 and the inner surface 12 are arranged opposite to each other along the thickness direction of the glass body 10. When the glass body 10 is installed on the door 202 and the door 202 is closed (doorway 2011), the inner surface 12 of the glass body 10 faces the inside of the vehicle 1000, and the outer surface 11 faces the outside of the vehicle 1000.

[0082] The glass body 10 can be a single-layer tempered glass, plastic glass, or other single-layer glass structure, or a semi-tempered laminated glass, fully tempered laminated glass, or tempered laminated glass, or other laminated glass structure. In this embodiment, as shown... Figure 4 As shown, the glass body 10 is illustrated using a single-layer glass structure as an example.

[0083] The glass body 10 also includes a fixing through hole 13. The fixing through hole 13 extends through the outer surface 11 and the inner surface 12 of the glass body 10. The fixing through hole 13 is used for a portion of the first vibrator 21 to pass through. It should be noted that the fixing through hole 13 is blocked by the outer edge 2022 of the window 2021.

[0084] The first vibrator 21 includes a first part 211 and a second part 212. Along the length direction of the first vibrator 21 (i.e., the thickness direction of the glass body 10), the first part 211 is connected to one end of the second part 212. The projection of the first part 211 lies within the projection of the second part 212. The first part 211 is used to pass through the fixed through hole 13.

[0085] In this embodiment, the first part 211 of the first vibrator 21 passes through the fixing through hole 13 of the glass body 10, and the end of the first part 211 away from the second part 212 is screwed to the nut 24. The nut 24 abuts against the outer surface 11 of the glass body 10, and the second part 212 of the first vibrator 21 abuts against the inner surface 12 of the glass body 10. Thus, the second part 212 and the nut 24 together clamp the glass body 10, realizing the locking and fixing of the first vibrator 21 and the glass body 10. In this embodiment, the vibration of the first vibrator 21 is directly transmitted to the glass body 10, causing the glass body 10 to vibrate together.

[0086] For the second connection method, please refer to [link / reference]. Figure 5 , Figure 5 for Figure 2 A schematic cross-sectional view of a portion of the structure of the second embodiment of the glass assembly shown.

[0087] In this embodiment, unlike the structure of the first embodiment described above, the glass assembly 100 further includes a bracket 30. The bracket 30 is snapped onto the edge of the glass body 10. The first vibrator 21 is mounted on the bracket 30 and fixed to the glass body 10 by the bracket 30, ensuring both the integrity of the glass body 10 and the connection strength between the first vibrator 21 and the glass body 10. In this embodiment, the vibration of the first vibrator 21 is transmitted to the bracket 30, and then to the glass body 10 through the bracket 30, thereby causing the glass body 10 to vibrate together.

[0088] The glass body 10 also includes a side surface 14. The side surface 14 is connected to the outer surface 11 and the inner surface 12.

[0089] The bracket 30 includes a first surface 31, a second surface 32, and two side surfaces. The first surface 31 and the second surface 32 are arranged opposite to each other along the thickness direction of the bracket 30. The two side surfaces are arranged opposite to each other along the length direction of the bracket 30, and both side surfaces are connected to the first surface 31 and the second surface 32.

[0090] The bracket 30 also includes a snap-fit ​​groove 33. The snap-fit ​​groove 33 is recessed on the first surface 31 of the bracket 30 and recessed towards the second surface 32. The extension direction of the snap-fit ​​groove 33 is the same as the length direction of the bracket 30, and the snap-fit ​​groove 33 extends through both sides. The snap-fit ​​groove 33 includes a first groove sidewall 331, a second groove sidewall 332, and a groove bottom wall 333. The first groove sidewall 331 and the second groove sidewall 332 are arranged opposite to each other and spaced apart along the width direction of the bracket 30, and both the first groove sidewall 331 and the second groove sidewall 332 are connected to the groove bottom wall 333. Both the first groove sidewall 331 and the second groove sidewall 332 are arranged at an angle to the groove bottom wall 333.

[0091] In this embodiment, the bracket 30 can be made of one or more of the following materials: metal or plastic, as long as the connection strength between the bracket 30 and the glass body 10 is met.

[0092] In this embodiment, the first vibrator 21 is located on one side of the support 30 in the width direction and is connected to the support 30. Furthermore, the first vibrator 21 is closer to the second groove sidewall 332 than the first groove sidewall 331. That is, the first vibrator 21 is located on the side of the glass body 10 facing the interior of the vehicle 1000. The first vibrator 21 can be fixed to the support 30 by means of bolting, adhesive, or other methods not limited to bolting or gluing.

[0093] In this embodiment, the glass body 10 extends into the locking groove 33 of the bracket 30 and is clamped and fixed by the first groove sidewall 331 and the second groove sidewall 332. Specifically, the side surface 14 of the glass body 10 faces and abuts against the bottom wall 333 of the locking groove 33. The outer surface 11 of the glass body 10 faces and abuts against the first groove sidewall 331 of the locking groove 33. The inner surface 12 of the glass body 10 faces and abuts against the second groove sidewall 332 of the locking groove 33. In some embodiments, the outer surface 11 of the glass body 10 may face and abut against the second groove sidewall 332 of the locking groove 33. The inner surface 12 of the glass body 10 may face and abut against the first groove sidewall 331 of the locking groove 33.

[0094] In this embodiment, the clamping strength of the first groove sidewall 331 and the second groove sidewall 332 on the glass body 10 is sufficient to prevent the bracket 30 and the first vibrator 21 from falling off the glass body 10. In other embodiments, adhesive can be filled between the glass body 10 and the bracket 30 to further improve the connection strength between the bracket 30 and the glass body 10, ensuring that the bracket 30 and the first vibrator 21 are stably fixed to the glass body 10.

[0095] In this embodiment, the contents that are the same as those in the first embodiment described above will not be repeated here.

[0096] For the third connection method, please refer to [link / reference]. Figure 6 , Figure 6 for Figure 2 A schematic cross-sectional view of a portion of the structure of the third embodiment of the glass assembly shown.

[0097] In this embodiment, unlike the structure of the second embodiment described above, the bracket 30 is mounted on one side of the glass body 10 in the thickness direction, the first vibrator 21 is mounted in the snap-fit ​​groove 33 of the bracket 30, and is fixed to the glass body 10 by the bracket 30.

[0098] Specifically, the second surface 32 of the bracket 30 is bonded to the inner surface 12 of the glass body 10. Along the thickness direction of the glass body 10, the first groove sidewall 331 and the second groove sidewall 332 of the bracket 30 both extend away from the glass body 10. The first vibrator 21 is housed in the snap-fit ​​groove 33 and is held by the first groove sidewall 331 and the second groove sidewall 332. The first vibrator 21 can be locked and fixed to the bracket 30 by means of bolts or other methods.

[0099] In some embodiments, the structure of the bracket 30 is changed, and the first groove sidewall 331 and the second groove sidewall 332 of the bracket 30 are connected and together form the groove sidewall of the locking groove 33. That is, the groove sidewall surrounds the outside of the first vibrator 21 to limit and hold the first vibrator 21.

[0100] In some embodiments, the bracket 30 may not have a snap-fit ​​groove 33, and the first vibrator 21 may be directly mounted on the first surface 31 of the bracket 30, as long as the connection strength between the first vibrator 21 and the bracket 30 is met.

[0101] In some embodiments, glue may be filled between the first vibrator 21 and the bracket 30 to further improve the connection strength between the bracket 30 and the first vibrator 21, ensuring that the first vibrator 21 is stably fixed on the bracket 30.

[0102] In this embodiment, the contents that are the same as those in the first embodiment described above will not be repeated here.

[0103] For the fourth connection method, please refer to [link / reference]. Figure 7 , Figure 7 for Figure 2 A schematic cross-sectional view of a portion of the structure of the fourth embodiment of the glass assembly shown.

[0104] In this embodiment, unlike the second embodiment described above, the glass body 10 is a laminated glass structure. The glass body 10 includes an outer glass plate 15, an intermediate layer 16, and an inner glass plate 17. Along the thickness direction of the glass body 10, the outer glass plate 15, the intermediate layer 16, and the inner glass plate 17 are sequentially stacked and connected. When the glass body 10 is installed on the door 202 and the door 202 is closed (doorway 2011), the outer glass plate 15 faces the outside of the vehicle 1000, and the inner glass plate 17 faces the inside of the vehicle 1000.

[0105] The outer glass panel 15 also includes a first surface 151, a second surface 152, and a first side surface 153. The first surface 151 and the second surface 152 are disposed opposite to each other along the thickness direction of the outer glass panel 15. The first side surface 153 is connected to the second surface 152 and the outer surface 11. The first surface 151 of the outer glass panel 15 can be regarded as the outer surface of the outer glass panel 15, or as the outer surface 11 of the glass body 10. The second surface 152 of the outer glass panel 15 can be regarded as the inner surface of the outer glass panel 15.

[0106] The inner glass plate 17 also includes a third surface 171, a fourth surface 172, and a second side surface 173. The fourth surface 172 and the third surface 171 are disposed opposite to each other along the thickness direction of the inner glass plate 17. The second side surface 173 connects the third surface 171 and the inner surface 12. The third surface 171 of the inner glass plate 17 can be regarded as the inner surface of the inner glass plate 17, and the fourth surface 172 of the inner glass plate 17 can be regarded as the outer surface of the inner glass plate 17, or as the inner surface 12 of the glass body 10.

[0107] The intermediate layer 16 includes a first connecting surface 161, a second connecting surface 162, and a third side surface 163. The first connecting surface 161 and the second connecting surface 162 are disposed along the thickness direction of the intermediate layer 16. The third side surface 163 is connected to the first connecting surface 161 and the second connecting surface 162.

[0108] In this embodiment, the first connecting surface 161 of the intermediate layer 16 is connected to the second surface 152 of the outer glass plate 15. The second connecting surface 162 of the intermediate layer 16 is connected to the third surface 171 of the inner glass plate 17. The intermediate layer 16 is adhesive, which can bond the outer glass plate 15 and the inner glass plate 17 together to form a laminated glass structure, thereby improving the overall structural strength of the glass body 10 and preventing glass shards from flying and injuring occupants inside the vehicle 1000 after the outer glass plate 15 and the inner glass plate 17 break. In addition, the first side surface 153 of the outer glass plate 15, the second side surface 173 of the inner glass plate 17, and the third side surface 163 of the intermediate layer 16 together constitute the side surface 14 of the glass body 10.

[0109] In this embodiment, unlike the structure of the bracket 30 in the second embodiment described above, the first groove sidewall 331 is used to be embedded from the side 14 of the glass body 10 between the inner glass plate 17 and the intermediate layer 16, or between the outer glass plate 15 and the intermediate layer 16. The length of the first groove sidewall 331 is greater than the length of the second groove sidewall 332, that is, the distance from the end face of the first groove sidewall 331 away from the groove bottom wall 333 to the groove bottom wall 333 is greater than the distance from the end face of the second groove sidewall 332 away from the groove bottom wall 333 to the groove bottom wall 333. The length of the first groove sidewall 331 is less than the length of the glass body 10.

[0110] The thickness and length of the first groove sidewall 331 are determined according to the specifications of the glass body 10, provided that its thickness does not affect the overall thickness of the glass body 10, and its length ensures sufficient connection strength between the support 30 and the glass body 10. For example, the length of the first groove sidewall 331 is greater than or equal to 10 mm and less than or equal to 100 mm. The thickness of the first groove sidewall 331 is greater than or equal to 0.2 mm and less than or equal to 2 mm. The thickness and length of the second groove sidewall 332 are set according to the actual production requirements of the glass body 10 product. This application does not impose any limitations on this.

[0111] In this embodiment, the outer glass plate 15, the intermediate layer 16, and the inner glass plate 17 are stacked sequentially along the thickness direction of the glass body 10. The first groove sidewall 331 of the bracket 30 is inserted between the intermediate layer 16 and the inner glass plate 17. The two surfaces of the first groove sidewall 331 in the thickness direction are respectively connected to the second connecting surface 162 of the intermediate layer 16 and the third surface 171 of the inner glass plate 17. The intermediate layer 16 can bond the first groove sidewall 331 together, and the length of the first groove sidewall 331 is greater than the length of the second groove sidewall 332. The first groove sidewall 331 extends into the glass body 10. The length and thickness of the first groove sidewall 331 ensure that the first groove sidewall 331 and the intermediate layer 16 have sufficient contact area and ensure the connection strength between the bracket 30 and the glass body 10. In addition, the intermediate layer 16 and the inner glass plate 17 together clamp the first groove sidewall 331, which further increases the connection strength between the first groove sidewall 331 and the glass body 10; thereby increasing the connection strength between the bracket 30 and the glass body 10 and preventing the bracket 30 from falling off the glass body 10.

[0112] The third surface 171 and the fourth surface 172 of the inner glass plate 17 are opposite to and abut against the first groove sidewall 331 and the second groove sidewall 332, respectively. The second side surface 173 of the inner glass plate 17 is opposite to and abuts against the bottom wall 333 of the locking groove 33. It can be understood that while the bracket 30 is installed with the glass body 10, the inner glass plate 17 is disposed in the locking groove 33 of the bracket 30 and is clamped by the first groove sidewall 331 and the second groove sidewall 332. The locking groove 33 can play a positioning role in the installation of the bracket 30 and the inner glass plate 17, ensuring the assembly accuracy of the inner glass plate 17 and the bracket 30. In some embodiments, glue can also be filled between the inner glass plate 17 and the bracket 30 to improve the connection strength between the bracket 30 and the inner glass plate 17, ensuring that the first vibrator 21 and the bracket 30 are stably fixed on the glass body 10.

[0113] In some other embodiments, the first groove sidewall 331 of the bracket 30 can be inserted between the outer glass plate 15 and the intermediate layer 16. The two surfaces of the first groove sidewall 331 in the thickness direction are respectively connected to the first connecting surface 161 of the intermediate layer 16 and the second surface 152 of the outer glass plate 15. At the same time, the intermediate layer 16 and the inner glass plate 17 are disposed in the snap-fit ​​groove 33 and are clamped by the first groove sidewall 331 and the second groove sidewall 332.

[0114] In some other embodiments, the first groove sidewall 331 of the bracket 30 can be inserted between the outer glass plate 15 and the intermediate layer 16 and connected to them. Simultaneously, the outer glass plate 15 is disposed within the snap-fit ​​groove 33 of the bracket 30 and is held by the first groove sidewall 331 and the second groove sidewall 332. The snap-fit ​​groove 33 provides positioning for the bracket 30 and the outer glass plate 15, ensuring the assembly accuracy of the outer glass plate 15 and the bracket 30. In some embodiments, adhesive can be filled between the outer glass plate 15 and the bracket 30 to improve the connection strength between the bracket 30 and the outer glass plate 15, ensuring that the first vibrator 21 and the bracket 30 are stably fixed to the glass body 10.

[0115] In some other embodiments, the first groove sidewall 331 of the bracket 30 can be inserted between the inner glass plate 17 and the intermediate layer 16 and connected to the inner glass plate 17 and the intermediate layer 16. Meanwhile, the intermediate layer 16 and the outer glass plate 15 are disposed in the snap-fit ​​groove 33 of the bracket 30 and are clamped by the first groove sidewall 331 and the second groove sidewall 332.

[0116] It should be noted that there are various ways to install the bracket 30 and the laminated glass. In actual production, the connection method between the bracket 30 and the glass body 10 is not limited to the examples mentioned above.

[0117] In related technologies, with the popularization of new energy vehicles, the application of hidden door handles and electric locks is becoming increasingly widespread. However, this also brings safety issues. For example, when a vehicle encounters an accident or a battery fire, the vehicle may automatically shut off, making it impossible to open the doors for escape. In such cases, breaking the car window becomes the primary means of escape for occupants. Typically, people use hammers or other hard objects to break the window for escape, but this method is easily limited by space, difficult to implement in crisis situations, and time-consuming, thus affecting the vehicle's safety in emergency situations.

[0118] In this embodiment, a glass assembly 100 is provided, comprising a glass body 10 and a window-breaking device 20 connected to the glass body 10. The window-breaking device 20 includes a first vibrator 21. When an emergency is detected in the vehicle 1000, the first vibrator 21 is rapidly driven to vibrate, and the vibration frequency of the first vibrator 21 is adjusted to match the natural frequency of the glass body 10, achieving resonance between the glass body 10 and the first vibrator 21, until the amplitude of the glass body 10 exceeds the material limit of the glass body 10, causing the glass body 10 to break. In this embodiment, in an emergency, by combining ultrasonic vibration and an electronic control system, the window-breaking device 20 can respond automatically and quickly without human intervention, is not limited by operating space, and greatly saves escape time for occupants, ensuring the safety of the vehicle 1000.

[0119] In addition, the vibration frequency of the first vibrator 21 reaches a predetermined frequency, which can also be used for de-icing. The window breaking device 20 may also include a second vibrator, which reaches a predetermined frequency and can be used to remove water droplets or dust from the glass body 10.

[0120] In some embodiments, the window breaking device 20 may also be equipped with an external switch, which can turn the window breaking function of the window breaking device 20 on or off. When the door 202 of the vehicle 1000 cannot be opened, the driver and passengers can use the external switch to break the glass body 10 and get out of the vehicle through the window 2021.

[0121] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
