Description

Technical Field

[0001] This application relates to the field of glass technology, and in particular to a glass assembly and a vehicle. Background Technology

[0002] With the rapid development of automotive technology, laminated glass has been widely used in modern automobile manufacturing due to its superior safety performance and additional functions such as dimming and sound insulation. More and more cars, especially new energy vehicles, are equipped with functional laminated glass for their side windows or rear windshields to achieve even more additional functions. However, the way laminated glass is assembled in these technologies makes it difficult to detach from the vehicle body in emergency situations, such as collisions, which greatly affects the efficiency of rescue and escape for occupants. Even with escape devices in these technologies, such as manual window breakers, not only do they rely on occupant operation, but their effectiveness in breaking laminated glass is also limited. Summary of the Invention

[0003] Therefore, it is necessary to overcome the shortcomings of existing technologies and provide a glass assembly and vehicle that can improve the separation efficiency and effect of laminated glass in emergency situations.

[0004] On one hand, this application provides a glass assembly, comprising:

[0005] Laminated glass, the laminated glass comprising a first glass and a second glass stacked together, wherein a portion of the first glass protruding relative to the outer edge of the second glass forms an extension;

[0006] A connector, which is connected to the extension, and further configured to connect to the vehicle body sheet metal; and

[0007] A blasting device is connected to the laminated glass. The blasting device includes a base, a drive mechanism, and a striker. The base is connected to the laminated glass, the drive mechanism is connected to the base, and the drive mechanism is also connected to the striker. When the striker is in its initial position, there is a gap between the striker and the laminated glass. When the drive mechanism is triggered, it drives the striker, causing the striker to move toward the laminated glass and shatter the first glass.

[0008] In one embodiment, the laminated glass further includes an intermediate layer located between the first glass and the second glass, and the extension protrudes relative to the outer edge of the intermediate layer.

[0009] In one embodiment, when the first glass is an outer glass and the second glass is an inner glass, the base is connected to the second glass, and the second glass has a first clearance hole and the intermediate layer has a second clearance hole. The first clearance hole and the second clearance hole are both set corresponding to the position of the striker.

[0010] In one embodiment, the connector and the second glass are connected to the same side of the first glass and are spaced apart.

[0011] In one embodiment, the shortest distance between the connector and the second glass is ≥0.5mm.

[0012] In one embodiment, when the first glass is an outer sheet and the second glass is an inner sheet, the base is connected to the extension, and the base, the connector, and the second glass are all located on the same side of the first glass, with the portion of the first glass opposite to the striker spaced apart from the connector.

[0013] In one embodiment, when the first glass is an inner glass and the second glass is an outer glass, the base is connected to the first glass, and both the base and the connector are located on the side of the first glass away from the second glass. The part of the first glass opposite to the striker is spaced apart from the connector.

[0014] In one embodiment, the laminated glass has a polygonal structure; each side of the first glass corresponds to each side of the second glass, one side of the first glass is aligned with one side of the second glass along the thickness direction of the laminated glass, and the remaining sides of the first glass protrude relative to the remaining sides of the corresponding second glass to form the extension; or, each side of the first glass corresponds to each side of the second glass, and each side of the first glass protrudes relative to the corresponding sides of the second glass to form the extension.

[0015] In one embodiment, the extension includes a first connecting surface, a second connecting surface, and a side surface, the first connecting surface and the second connecting surface being disposed opposite to each other in the thickness direction of the extension, the first connecting surface being oriented toward the outside of the vehicle, the side surface being connected between the first connecting surface and the second connecting surface, and the connector being connected to the second connecting surface;

[0016] The glass assembly further includes an edge covering the side surface, at least a portion of the first connecting surface, and at least a portion of the second connecting surface;

[0017] Wherein, the connector is connected to the second connecting surface and is in contact with or spaced from the edge connected to the second connecting surface; or, the connector is connected to the edge and is connected to the second connecting surface through the edge.

[0018] In one embodiment, when the first glass is an outer pane and the second glass is an inner pane, the projection of the second glass onto the first glass along the thickness direction of the laminated glass is offset from the projection of the edging onto the first glass along the thickness direction of the laminated glass. The connector is connected to the second connecting surface, and the connector and the second glass are connected to the same side of the first glass and spaced apart. Alternatively, when the first glass is an outer pane and the second glass is an inner pane, the edging covers the outer edge of the first glass and is spaced apart from the outer edge of the second glass. The connector is connected to the edging, and the projection of the connector onto the first glass along the thickness direction of the laminated glass is within the range of the projection of the edging onto the first glass along the thickness direction of the laminated glass.

[0019] In one embodiment, when the first glass is an inner glass and the second glass is an outer glass, the edging covers the outer edge of the first glass and abuts against the outer edge of the second glass. The connector is connected to the second connecting surface and is respectively connected to the second glass on both sides of the thickness direction of the first glass. The projection of the connector on the first glass along the thickness direction of the laminated glass is offset from the projection of the second glass on the first glass along the thickness direction of the laminated glass.

[0020] Alternatively, the connector is connected to the edging, and the projection of the connector on the first glass along the thickness direction of the laminated glass is located within the range of the projection of the edging on the first glass along the thickness direction of the laminated glass.

[0021] In one embodiment, the blasting device further includes a locking component disposed between the drive mechanism and the firing pin, and the locking component is rotatably disposed on the base. The locking component has a locked position and an unlocked position. When the locking component is in the locked position, the locking component locks the drive mechanism; when the locking component is in the unlocked position, the locking component unlocks the drive mechanism, and the drive mechanism is triggered.

[0022] In one embodiment, the base includes a fixing sleeve and a positioning plate. One end of the fixing sleeve is connected to the laminated glass, and the positioning plate is disposed inside the fixing sleeve and connected to the fixing sleeve. The positioning plate has a through hole and an unlocking hole communicating with the through hole.

[0023] The locking assembly includes a sliding insert and a rotating member. The sliding insert is rotatably disposed within the fixed sleeve and is located between the positioning plate and the laminated glass. The striking pin is connected to the end of the sliding insert near the laminated glass. The driving mechanism includes an elastic member connected between the sliding insert and the positioning plate. The rotating member passes through the through hole and is connected to the sliding insert. The rotating member is located on the side of the positioning plate opposite to the laminated glass.

[0024] The rotating component can rotate relative to the positioning plate. When the rotating component is opposite to the unlocking hole, the rotating component can completely pass through the unlocking hole, and the locking component is located in the unlocking position. When the rotating component is misaligned with the unlocking hole, the positioning plate can abut against and position the rotating component, and the locking component is located in the locking position.

[0025] In one embodiment, the locking assembly further includes a limiting block connected to the end of the rotating member, the limiting block being located on the side of the positioning plate opposite to the laminated glass; the positioning plate on the side opposite to the laminated glass is provided with a stop member, the stop member abutting against the limiting block; when the rotating member rotates and causes the limiting block to act on the stop member with a pressure greater than a preset value, the limiting block and the rotating member separate; when the limiting block and the rotating member are not separated, and the rotating member is positioned opposite the unlocking hole, the positioning plate abuts against and positions the limiting block.

[0026] In one embodiment, there are two limiting blocks, which are connected to the opposite ends of the rotating member. There are also two blocking members, which are configured to correspond one-to-one with the two limiting blocks.

[0027] In one embodiment, the abutment is configured as a stop block, and the stop block has a first end and a second end opposite to each other along the rotation direction of the rotating member; the first end has a relief recess that can avoid the rotating member, and the first end abuts and engages with the limiting block; the second end abuts and engages with the rotating member; the unlocking hole is located in the area between the two abutments.

[0028] In one embodiment, the blasting device further includes a protective cover detachably connected to the other end of the fixed sleeve.

[0029] In one embodiment, the locking assembly further includes an electrically controlled drive and a locking member disposed between the rotating member and the sliding insert; the electrically controlled drive is mounted on the rotating member and connected to the locking member; the electrically controlled drive can drive the locking member to a locked position or a released position; when the locking member is in the locked position, the locking member is fixedly connected to the sliding insert; when the locking member is in the released position, the locking member releases the sliding insert.

[0030] On the other hand, this application provides a vehicle, including a body panel and the glass assembly, wherein the glass assembly is mounted on the body panel.

[0031] The aforementioned glass assembly and vehicle utilize a design where the outer edge of the second glass in the laminated glass is recessed relative to the first glass, creating an extension within the laminated glass. This ensures that only the first glass is fixed to the vehicle body sheet metal via connectors. Therefore, in an emergency, when occupants wish to escape by breaking a window, a blasting device is used to trigger the drive mechanism. This mechanism drives a striker, causing it to move towards the laminated glass and shatter the first glass. The laminated glass then breaks and separates from the vehicle body sheet metal, thus improving the separation efficiency and effectiveness of the laminated glass. Attached Figure Description

[0051] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0052] It should be noted that in the laminated glass of this embodiment, the outer glass refers to the glass that is close to the external environment of the vehicle, while the inner glass refers to the glass that is close to the internal environment of the vehicle.

[0053] Embodiments of this application provide a glass assembly and a vehicle.

[0054] For example, means of transportation include, but are not limited to, cars, buses, trains, and high-speed trains. This embodiment specifically uses a car as an example of means of transportation, but it is not limited to this.

[0055] Please see Figure 1 , Figure 1 This is a schematic diagram of a vehicle 10 provided in an embodiment of this application. The vehicle 10 may include a body panel 11 and a glass assembly 12. The glass assembly 12 is mounted on the body panel 11.

[0056] It should be noted that, Figure 1 The purpose of this illustration is merely to depict the connection relationship between the body sheet metal 11 and the glass assembly 12, and is not to specifically limit the connection positions, specific structures, and quantities of each device. In other embodiments of this application, the vehicle 10 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0057] The structure of the glass assembly 12 will be described in detail below.

[0058] See Figure 1 An embodiment of this application provides a glass assembly 12, including laminated glass 121 and connector 122.

[0059] For example, please refer to Figure 6 , Figure 7 , Figure 9 , Figure 11 and Figure 13In any case, the glass assembly 12 also includes an edging 123. The edging 123 can be installed on the outer edge of the laminated glass 121 and extends along the circumferential direction of the laminated glass 121. The edging 123 covers at least a portion of the outer edge of the laminated glass 121. A connector 122 connects the edging 123 and the body panel 11. Alternatively, the connector 122 connects the laminated glass 121 and the body panel 11. The connector 122 is used to securely connect the edging 123 or the laminated glass 121 to the body panel 11.

[0060] Of course, the glass assembly 12 may also be without the need for the bezel 123, for example... Figure 5 , Figure 8 , Figure 10 and Figure 12 As shown.

[0061] The laminated glass 121 can be one or more of the following: side window glass, rear windshield glass, and corner window glass of a vehicle. The edging 123 and the laminated glass 121 can be connected to form an integral structure through an integrated injection molding process. Alternatively, the edging 123 and the laminated glass 121 can be separate structures, assembled together by assembly methods such as bonding.

[0062] Please refer to the following: Figure 1 and Figure 6 The laminated glass 121 may include a first glass 1211, a second glass 1212, and an intermediate layer 1213. In the thickness direction of the laminated glass 121, the first glass 1211, the intermediate layer 1213, and the second glass 1212 are stacked sequentially.

[0063] In this embodiment, the first glass 1211 can be the outer glass pane, and the second glass 1212 is the inner glass pane accordingly; conversely, when the first glass 1211 is the inner glass pane, the second glass 1212 is the outer glass pane accordingly. The specific arrangement of the first glass 1211 and the second glass 1212 is not limited in this embodiment and can be set according to actual needs.

[0064] An extension 1214 is formed from the portion of the first glass 1211 that protrudes relative to the outer edge of the second glass 1212. Specifically, the outer edge of the first glass 1211 protrudes relative to the outer edge of the second glass 1212. That is, the outer edge of the second glass 1212 is recessed relative to the outer edge of the first glass 1211. The extension 1214 is formed from the portion of the first glass 1211 that protrudes relative to the outer edge of the second glass 1212. The extension 1214 also protrudes relative to the outer edge of the intermediate layer 1213. That is, the outer edge of the intermediate layer 1213 is recessed relative to the outer edge of the first glass 1211. The outer edge of the extension 1214 can be covered by an edging 123. That is, the outer edge of the first glass 1211 can be covered by the edging 123. The outer edges of the intermediate layer 1213 and the second glass 1212 can both be spaced apart from the edging 123.

[0065] The first glass 1211 can be tempered glass. It is understood that designing the first glass 1211 as tempered glass allows it to shatter quickly and completely upon encountering single or multiple point impacts, effectively dispersing the impact force. The second glass 1212 can also be tempered glass, giving it better strength.

[0066] In some other embodiments, the first glass 1211 can be designed as tempered glass, and the second glass 1212 as ordinary glass. Alternatively, the second glass 1212 can be designed as tempered glass, and the first glass 1211 as ordinary glass. The materials of the first glass 1211 and the second glass 1212 can be determined according to the usage requirements and are not strictly limited.

[0067] In this embodiment, the outer peripheral surface of the intermediate layer 1213 can be flush with the outer peripheral surface of the second glass 1212. That is, the inward length of the intermediate layer 1213 relative to the first glass 1211 can be equal to the inward length of the second glass 1212 relative to the first glass 1211. The outer peripheral surface of the intermediate layer 1213 is the outer surface surrounding the central axis of the intermediate layer 1213. The outer peripheral surface of the second glass 1212 is the outer surface surrounding the central axis of the second glass 1212.

[0068] In some other embodiments, the outer peripheral surface of the intermediate layer 1213 may not be flush with the outer peripheral surface of the second glass 1212. Specifically, the outer edge of the intermediate layer 1213 may protrude relative to the outer edge of the second glass 1212. Alternatively, the outer edge of the intermediate layer 1213 may be recessed relative to the outer edge of the second glass 1212. The key is to ensure that the outer edges of both the intermediate layer 1213 and the second glass 1212 are spaced apart from the edging 123.

[0069] In this embodiment, the intermediate layer 1213 may be adhesive to securely connect the first glass 1211 and the second glass 1212. Exemplarily, the material of the intermediate layer 1213 may be polyvinyl butyral (PVB).

[0070] Understandably, when the first glass 1211 breaks due to external force or excessively cold weather, it will produce a large number of glass fragments. These fragments flying everywhere can cause significant injury to people in the vicinity. Using an adhesive material as the interlayer 1213 can effectively fix the glass fragments, prevent them from flying, reduce the probability of glass fragments injuring people in the vicinity, and thus greatly improve the safety of the laminated glass 121 and enhance its overall strength.

[0071] The intermediate layer 1213 may include a functional layer. For example, the intermediate layer 1213 may include a dimming layer, a sound insulation layer, etc. The functional layer may include wires. The wires are used to connect to a power source to meet the power requirements of the functional layer, thereby enabling the functional layer to perform its functions.

[0072] For example, the extension 1214 may include a first connecting surface 12141, a second connecting surface 12142, and a side surface 12143. The first connecting surface 12141 and the second connecting surface 12142 are disposed opposite to each other in the thickness direction of the extension 1214. The first connecting surface 12141 faces the exterior of the vehicle 10. The first connecting surface 12141 is formed on the exterior surface of the first glass 1211 facing the vehicle 10. The second connecting surface 12142 faces the interior of the vehicle 10. The second connecting surface 12142 is formed on the interior surface of the first glass 1211 facing the vehicle 10. The side surface 12143 connects between the first connecting surface 12141 and the second connecting surface 12142. The side surface 12143 is the outer peripheral surface of the first glass 1211. The outer peripheral surface of the first glass 1211 is the outer surface surrounding the central axis of the first glass 1211. Side 12143, at least a portion of the first connecting surface 12141 and at least a portion of the second connecting surface 12142 are covered by edging 123.

[0073] In summary, of the laminated glass 121, only the outer edge of the first glass 1211 is embedded in the edging 123, which consists of the first glass 1211, the second glass 1212, and the intermediate layer 1213. The second glass 1212 and the intermediate layer 1213 are both separate from the edging 123. The connection relationship between the laminated glass 121, the edging 123, and the connector 122 will be described in detail below through three specific embodiments.

[0074] In a first possible embodiment, the edging 123 covers the outer edge of the extension 1214. That is, the edging 123 covers the outer edge of the first glass 1211. The areas of the edging 123 covering the first connecting surface 12141 and the second connecting surface 12142 of the extension 1214 can be approximately equal. Alternatively, the area of ​​the edging 123 covering the first connecting surface 12141 of the extension 1214 can be larger or smaller than the area of ​​the edging 123 covering the second connecting surface 12142. The edging 123 can contact or be spaced from the outer edge of the second glass 1212. That is, the shortest distance D1 between the edging 123 and the second glass 1212 can be greater than or equal to 0 mm. Further, D1 can be greater than or equal to 0.5 mm. The edging 123 can contact or be spaced from the outer edge of the intermediate layer 1213. That is, the shortest distance D2 between the edging 123 and the intermediate layer 1213 can be greater than or equal to 0 mm. Further, D2 can be greater than or equal to 0.5 mm. The shortest distance D2 between the edging 123 and the intermediate layer 1213 can be equal to the shortest distance D1 between the edging 123 and the second glass 1212.

[0075] Alternatively, in this embodiment, the shortest distance D2 between the edging 123 and the intermediate layer 1213 can also be greater than the shortest distance D1 between the edging 123 and the second glass 1212. Alternatively, the shortest distance D2 between the edging 123 and the intermediate layer 1213 can also be less than the shortest distance D1 between the edging 123 and the second glass 1212.

[0076] It is understood that only the outer edge of the first glass 1211 in the laminated glass 121 is embedded in and fixedly connected to the edging 123. Therefore, when the laminated glass 121 is subjected to external force, the external force only needs to break the first glass 1211, and the laminated glass 121 can break between the second glass 1212 and the edging 123. After breaking, the entire laminated glass 121 is not connected to other components (such as the edging 123, the body sheet metal 11, etc.), and can be completely detached from the body sheet metal 11, ensuring that the large number of fragments generated after the first glass 1211 is damaged will not become a source of injury, providing a safety barrier for personnel. In addition, in this embodiment, the outer edge of the second glass 1212 can be spaced apart from the edging 123. This gap between the second glass 1212 and the edging 123 can be used to accommodate the wires of the functional layer, thereby allowing the wires of the functional layer to enter the vehicle interior through the gap between the second glass 1212 and the edging 123 to connect to the power supply inside the vehicle. While ensuring the overall sealing of the glass assembly 12 is not compromised, electrical connections to the functional layers can be achieved, thereby maintaining the functional integrity of the functional layers. Furthermore, the wires are isolated from the vehicle exterior by the first glass 1211 and the edging 123, preventing them from being corroded by moisture from outside the vehicle.

[0077] In this embodiment, the connector 122 connects the surface of the edging 123 facing the interior of the vehicle and the body sheet metal 11. That is, the connector 122 is connected to the extension 1214 via the edging 123 to fix the extension 1214 to the body sheet metal 11. The projection of the connector 122 on the first glass 1211 along the thickness direction of the laminated glass 121 is located within the range of the projection of the edging 123 on the first glass 1211 along the thickness direction of the laminated glass 121. That is, the projection of the connector 122 on the first glass 1211 along the thickness direction of the laminated glass 121 is offset from the projection of the second glass 1212 on the first glass 1211 along the thickness direction of the laminated glass 121, and is also offset from the projection of the intermediate layer 1213 on the first glass 1211 along the thickness direction of the laminated glass 121. This allows the wire to enter the vehicle interior through the gap between the second glass 1212 and the edging 123 without being blocked by the connector 122, reducing the difficulty of wire assembly and improving production efficiency.

[0078] Furthermore, it is understandable that if the projection of the connector 122 on the first glass 1211 along the thickness direction of the laminated glass 121 coincides with the projection of the second glass 1212 on the first glass 1211 along the thickness direction of the laminated glass 121, then in an emergency, when the laminated glass 121 breaks from the second glass 1212 and the edging 123 due to external force, and people outside the vehicle attempt to push the broken laminated glass 121 from the outside to rescue the people inside the vehicle, the area near its outer edge of the second glass 1212 may be blocked by the connector 122, causing the people outside the vehicle to be unable to push the laminated glass 121, thereby affecting the rescue efficiency.

[0079] Therefore, in this embodiment, the projection of the connector 122 on the first glass 1211 along the thickness direction of the laminated glass 121 is offset from the projection of the second glass 1212 on the first glass 1211 along the thickness direction of the laminated glass 121, and is also offset from the projection of the intermediate layer 1213 on the first glass 1211 along the thickness direction of the laminated glass 121. In this way, when the laminated glass 121 breaks from the second glass 1212 and the edging 123 due to external force, the area around the outer edge of the second glass 1212 will not be blocked by the connector 122, thereby helping people outside the vehicle to quickly push the laminated glass 121 and achieve timely rescue of the people inside the vehicle.

[0080] In this embodiment, the connector 122 can be an adhesive. For example, the connector 122 can be polyurethane (PU).

[0081] In the second possible implementation, unlike the first implementation, the connector 122 can be a screw. The screw passes through the edging 123 and the body panel 11, and is secured by a nut located on the side of the body panel 11 opposite to the edging 123. The screw embedded in the edging 123 is also spaced apart from the extension 1214 embedded in the edging 123. That is, in this implementation, the connector 122 is connected to the extension 1214 via the edging 123 to securely connect the extension 1214 to the body panel 11.

[0082] In the third possible implementation, unlike the first implementation, the connector 122 is connected between the second connecting surface 12142 of the extension 1214 and the body sheet 11. That is, the connector 122 is directly connected to the extension 1214. Also, the connector 122 is connected between the first glass 1211 and the body sheet 11. The connector 122 may contact or be spaced from the portion of the edging 123 located between the second connecting surface 12142 and the body sheet 11. The connector 122 is connected to the second glass 1212 on the same side of the first glass 1211. The connector 122 may contact or be spaced from the second glass 1212. That is, the shortest distance D3 between the connector 122 and the second glass 1212 may be greater than or equal to 0 mm. Further, D3 may be greater than or equal to 0.5 mm. The connector 122 is also connected to the intermediate layer 1213 on the same side of the first glass 1211. The connector 122 can be in contact with or spaced from the intermediate layer 1213. That is, the shortest distance D4 between the connector 122 and the intermediate layer 1213 can be greater than or equal to 0 mm. Further, D4 can be greater than or equal to 0.5 mm. The shortest distance D4 between the connector 122 and the intermediate layer 1213 can also be equal to the shortest distance D3 between the connector 122 and the second glass 1212.

[0083] Alternatively, in this embodiment, the shortest distance D4 between the connector 122 and the intermediate layer 1213 may be greater than the shortest distance D3 between the connector 122 and the second glass 1212. Alternatively, the shortest distance D4 between the connector 122 and the intermediate layer 1213 may be less than the shortest distance D3 between the connector 122 and the second glass 1212.

[0084] In this embodiment, the projection of the second glass 1212 onto the first glass 1211 along the thickness direction of the laminated glass 121 is offset from the projection of the edging 123 onto the first glass 1211 along the thickness direction of the laminated glass 121. That is, the outer edge of the second glass 1212 is spaced apart from the edging 123. Similarly, the projection of the intermediate layer 1213 onto the first glass 1211 along the thickness direction of the laminated glass 121 is also offset from the projection of the edging 123 onto the first glass 1211 along the thickness direction of the laminated glass 121. That is, the outer edge of the intermediate layer 1213 is also spaced apart from the edging 123.

[0085] Understandably, in this embodiment, only the outer edge of the first glass 1211 is embedded in and fixedly connected to the edging 123 in the laminated glass 121. This allows the laminated glass 121 to detach completely from the vehicle body sheet metal 11 when subjected to external force, reducing the likelihood of injury to personnel from a large number of flying fragments generated after the first glass 1211 is damaged, thus providing a safety barrier for personnel. Furthermore, in this embodiment, the second glass 1212 can be spaced apart from the connector 122. This gap between the second glass 1212 and the connector 122 can also be used to accommodate the functional layer's wires, allowing the wires to enter the vehicle interior through the gap between the second glass 1212 and the connector 122 to connect to the vehicle's internal power supply. While ensuring the overall sealing of the glass assembly 12 is not compromised, electrical connection of the functional layer can be achieved, maintaining the functional integrity of the functional layer and preventing the wires from being corroded by moisture from outside the vehicle.

[0086] In this embodiment, the area of ​​the first connecting surface 12141 of the edging 123 covering the extension 1214 can be larger than the area of ​​the second connecting surface 12142 of the edging 123 covering the extension 1214, so that the second connecting surface 12142 of the extension 1214 is exposed more, so that the connector 122 is connected to the second connecting surface 12142.

[0087] In this embodiment, please refer to the relevant documentation. Figure 1 , Figure 15 and Figure 16 The laminated glass 121 can be a polygonal structure. Specifically, the first glass 1211, the second glass 1212, and the intermediate layer 1213 are all polygonal structures. The number of sides of the first glass 1211 is equal to the number of sides of the second glass 1212 and the intermediate layer 1213. All sides of the first glass 1211 correspond one-to-one with all sides of the second glass 1212 and all sides of the intermediate layer 1213. For example, the laminated glass 121 can be... Figure 16 The triangular structure shown. Alternatively, the laminated glass 121 can be... Figure 15 The quadrilateral structure shown is an example.

[0088] For one possible implementation, please refer to Figure 1 , Figure 17 and Figure 18 All edges of the first glass 1211 can be covered by the edging 123. One edge of the second glass 1212 can be covered by the edging 123. That is, the outer edge of one edge of the second glass 1212 is not recessed relative to the first glass 1211. The projections of the remaining edges of the second glass 1212 onto the first glass 1211 along the thickness direction of the laminated glass 121 are all misaligned with the projections of the edging 123 onto the first glass 1211 along the thickness direction of the laminated glass 121. That is, the remaining edges of the second glass 1212 are spaced apart from the edging 123. In other words, the outer edges of the remaining edges of the second glass 1212 are all recessed relative to the first glass 1211. One edge of the intermediate layer 1213 corresponding to the edge of the second glass 1212 covered by the edging 123 can also be covered by the edging 123. That is, the outer edge of one edge of the intermediate layer 1213 is not recessed relative to the first glass 1211. The projections of the remaining edges of the intermediate layer 1213 onto the first glass 1211 along the thickness direction of the laminated glass 121 are all offset from the projections of the edging 123 onto the first glass 1211 along the thickness direction of the laminated glass 121. That is, the remaining edges of the intermediate layer 1213 are spaced apart from the edging 123. In other words, the outer edges of the remaining edges of the intermediate layer 1213 are all recessed relative to the first glass 1211.

[0089] The positional relationship between the edge of the second glass 1212 and / or the intermediate layer 1213 that is spaced apart from the edge 123 and the connector 122 is described in the first, second and third embodiments above, and will not be repeated here.

[0090] In this embodiment, while ensuring the connection stability between the intermediate layer 1213 and the first glass 1211 and the second glass 1212, the intermediate layer 1213 may not have an edge covered by the edging 123. That is, all edges of the intermediate layer 1213 are spaced apart from the edging 123. In other words, the outer edges of all edges of the intermediate layer 1213 are recessed relative to the first glass 1211.

[0091] For an example, please refer to Figure 17 or Figure 18The laminated glass 121 has a polygonal structure. Each edge of the first glass 1211 corresponds to each edge of the second glass 1212. One edge of the first glass 1211 is aligned with one edge of the second glass 1212 along the thickness direction of the laminated glass 121. The remaining edges of the first glass 1211 protrude relative to the remaining edges of the corresponding second glass 1212, forming extensions 1214. In other words, the remaining edges of the first glass 1211 and the remaining edges of the corresponding second glass 1212 are offset along the thickness direction of the laminated glass 121. Furthermore, the remaining edges of the second glass 1212 are recessed relative to the remaining edges of the corresponding first glass 1211.

[0092] In one specific embodiment, please refer to Figure 17 or Figure 18 The laminated glass 121 may include a first edge 1215. The first edge 1215 is composed of the edge of the first glass 1211, the edge of the second glass 1212, and the edge of the intermediate layer 1213, and all of these edges are covered by an edge protector 123. Alternatively, the first edge 1215 may be composed of the edge of the first glass 1211 and the edge of the second glass 1212, and all of these edges are covered by the edge protector 123. The first edge 1215 of the laminated glass 121 can be any edge of the laminated glass 121. For example, this edge of the laminated glass 121 may be the edge of the laminated glass 121 near the bottom of the vehicle.

[0093] It should be noted that in this embodiment, there is only one first edge 1215. That is, the laminated glass 121 includes only one first edge 1215 to prevent the edge of the laminated glass 121 from being fixed too much in an emergency and unable to detach from the body sheet metal 11.

[0094] Understandably, in an emergency, when the laminated glass 121 is subjected to external force, only the edges of the first glass 1211 embedded within the edging 123 are more likely to separate from the vehicle body panel 11. The first edge 1215, where both the first glass 1211 and the second glass 1212 are embedded within the edging 123, has a more stable connection to the vehicle body panel 11 and is relatively less likely to separate from it under external force. Therefore, the first edge 1215 can act as a fulcrum, preventing the entire laminated glass 121 from completely detaching and flying out, thus improving the overall safety of the vehicle and ensuring the partial integrity of the laminated glass 121.

[0095] For example, please refer to Figure 17 The first glass 1211, the second glass 1212, and the intermediate layer 1213 are all quadrilateral structures. The outer edge of one side of the second glass 1212 is not recessed relative to the first glass 1211. The outer edges of the other three sides of the second glass 1212 are recessed relative to the first glass 1211. The outer edges of all four sides of the intermediate layer 1213 are recessed relative to the first glass 1211.

[0096] For example, please refer to Figure 18 The first glass 1211, the second glass 1212, and the intermediate layer 1213 are all triangular structures. The outer edge of one side of the second glass 1212 is not recessed relative to the first glass 1211. The outer edges of the other two sides of the second glass 1212 are recessed relative to the first glass 1211. The outer edges of all three sides of the intermediate layer 1213 are recessed relative to the first glass 1211.

[0097] For another possible implementation, please refer to [reference needed]. Figure 15 and Figure 16 The laminated glass 121 has a polygonal structure. Each edge of the first glass 1211 corresponds to each edge of the second glass 1212, and each edge of the first glass 1211 protrudes relative to the corresponding edge of the second glass 1212 to form an extension 1214. In other words, each edge of the first glass 1211 and the remaining edges of the corresponding second glass 1212 are offset along the thickness direction of the laminated glass 121. Furthermore, the remaining edges of the second glass 1212 are recessed relative to the remaining edges of the corresponding first glass 1211.

[0098] For another possible implementation, please refer to [reference needed]. Figure 15 and Figure 16 All edges of the first glass 1211 can be covered by the edging 123. The projections of all edges of the second glass 1212 onto the first glass 1211 along the thickness direction of the laminated glass 121 are offset from the projections of the edging 123 onto the first glass 1211 along the thickness direction of the laminated glass 121. That is, all edges of the second glass 1212 are spaced apart from the edging 123. In other words, the outer edges of all edges of the second glass 1212 are recessed relative to the first glass 1211. Similarly, the projections of all edges of the intermediate layer 1213 onto the first glass 1211 along the thickness direction of the laminated glass 121 are offset from the projections of the edging 123 onto the first glass 1211 along the thickness direction of the laminated glass 121. That is, all edges of the intermediate layer 1213 are spaced apart from the edging 123. In other words, the outer edges of all edges of the intermediate layer 1213 are recessed relative to the first glass 1211.

[0099] The positional relationship between the edge of the second glass 1212 and / or the intermediate layer 1213 that is spaced apart from the edge 123 and the connector 122 is described in the first, second and third embodiments above, and will not be repeated here.

[0100] Understandably, among all the edges of the laminated glass 121, only the first glass 1211 is embedded within and fixedly connected to the edging 123. Therefore, when the laminated glass 121 is subjected to external force, the laminated glass 121 can be completely detached from the vehicle body sheet 11, ensuring that fragments of the first glass 1211 will not become a source of injury, thus providing a safety barrier for personnel.

[0101] For example, please refer to Figure 15 The first glass 1211, the second glass 1212, and the intermediate layer 1213 are all quadrilateral structures. The outer edges of the four sides of the second glass 1212 are all recessed relative to the first glass 1211. The outer edges of the four sides of the intermediate layer 1213 are also recessed relative to the first glass 1211.

[0102] For example, please refer to Figure 16 The first glass 1211, the second glass 1212, and the intermediate layer 1213 are all triangular structures. The outer edges of the three sides of the second glass 1212 are all recessed relative to the first glass 1211. The outer edges of the three sides of the intermediate layer 1213 are also recessed relative to the first glass 1211.

[0103] Understandably, laminated glass 121 has become a widely used type of glass in automobile manufacturing due to its excellent safety performance and additional functions such as dimming and sound insulation. However, in order to improve the sealing and stability between the laminated glass 121 and the vehicle body, the outer edge of the laminated glass 121 is usually tightly connected to the vehicle body, or even embedded in the vehicle body. For example, the outer edge of the laminated glass 121 may be embedded in the edging 123, making it difficult to quickly separate from the body sheet metal 11 in emergency situations (such as collisions). This greatly affects the efficiency of rescue and escape for occupants.

[0104] Therefore, in this embodiment, by designing the outer edges of the second glass 1212 and the intermediate layer 1213 in the laminated glass 121 to be recessed relative to the first glass 1211, i.e., the first glass 1211 can form an extension 1214 protruding relative to the second glass 1212 and the intermediate layer 1213, so that only the outer edge of the first glass 1211 is embedded in the edging 123, while the outer edges of the second glass 1212 and the intermediate layer 1213 only contact or are spaced apart from the edging 123. In an emergency, when people outside the vehicle want to break the window to rescue someone or people inside the vehicle want to break the window to escape, they only need to break the first glass 1211, and the laminated glass 121 can break between the second glass 1212 and the edging 123, and then detach from the vehicle body panel 11. That is, the thickness of the laminated glass 121 that rescuers need to break is greatly reduced, making it easier for the laminated glass 121 to detach from the vehicle body panel 11, and greatly improving rescue efficiency. Furthermore, in an emergency, the laminated glass 121 can break off from between the second glass 1212 and the edging 123 at the expected position, which not only improves the safety and reliability of the vehicle but also makes it easier to replace the broken laminated glass 121 later, thus improving the replacement efficiency of the laminated glass 121. Moreover, when the second glass 1212 and the edging 123 are spaced apart, the gap between the second glass 1212 and the edging 123 can be used for the wires of the functional layer to pass through, so that the functional layer can achieve its functional characteristics without compromising the sealing performance of the glass assembly 12, thereby enhancing the vehicle's sealing performance.

[0105] In this embodiment, the assembly process of the glass assembly 12 may include at least the following steps:

[0106] First, the second glass 1212 and the intermediate layer 1213 of the laminated glass 121 are designed to be recessed relative to the first glass 1211, so that the first glass 1211 can form an extension 1214 that protrudes relative to the second glass 1212 and the intermediate layer 1213.

[0107] Then, the laminated glass 121 is injection molded with an edge 123. This makes the edge 123 cover the outer edge of the first glass 1211 (i.e., the edge 123 covers the outer edge of the extension 1214) and is spaced apart from the second glass 1212 and the intermediate layer 1213.

[0108] Finally, liquid adhesive is applied between the surface of the edging 123 facing the vehicle interior and the body sheet metal 11. After the adhesive cures, a connector 122 is formed to connect the edging 123 and the body sheet metal 11, ensuring that the cured connector 122 does not contact the second glass 1212 and the intermediate layer 1213. Alternatively, liquid adhesive is applied between the second connecting surface 12142 of the extension 1214 and the body sheet metal 11. After the adhesive cures, a connector 122 is formed to connect the first glass 1211 and the body sheet metal 11, ensuring that the cured connector 122 does not contact the second glass 1212 and the intermediate layer 1213. Alternatively, a screw is placed between the edging 123 and the body sheet metal 11, passing through both. A nut is placed on the side of the body sheet metal 11 away from the edging 123 to secure the screw. A certain distance is maintained between the screw and the outer edges of both the second glass 1212 and the intermediate layer 1213.

[0109] Based on any of the foregoing embodiments, please refer to Figures 2 to 5 The glass assembly 12 also includes a blasting device 20. The blasting device 20 is connected to the laminated glass 121. The blasting device 20 includes a base 21, a drive mechanism 22, and a striking pin 25. The base 21 is connected to the laminated glass 121. The drive mechanism 22 is connected to the base 21 and also to the striking pin 25. When the striking pin 25 is in its initial position, there is a gap between the striking pin 25 and the laminated glass 121. After the drive mechanism 22 is triggered, it drives the striking pin 25, causing the striking pin 25 to move toward the laminated glass 121 and shatter the first glass 1211.

[0110] Understandably, laminated glass 121, with its superior safety performance and additional functions such as dimming and sound insulation, has become a widely used type of glass in the automotive manufacturing industry. The multi-layered structure of laminated glass 121 provides excellent impact protection for vehicle occupants. However, in order to improve the sealing and stability between laminated glass 121 and the vehicle body, the outer edge of laminated glass 121 is usually tightly connected to the vehicle body, or even embedded in the vehicle body. This makes it difficult for laminated glass 121 to quickly separate from the vehicle body in emergency situations (such as collisions), thus affecting the efficiency of rescue and escape for vehicle occupants.

[0111] The aforementioned glass assembly 12, by designing the outer edge of the second glass 1212 in the laminated glass 121 to be recessed relative to the first glass 1211, allows for the formation of an extension 1214 within the laminated glass 121. This ensures that only the first glass 1211 is fixedly connected to the vehicle body sheet metal 11 via the connector 122. Therefore, in an emergency, when occupants wish to escape by breaking the window, they only need to activate the explosive device 20 to trigger the drive mechanism 22. The drive mechanism 22 then drives the impact pin 25, causing the impact pin 25 to move towards the laminated glass 121 and shatter the first glass 1211. The laminated glass 121 breaks and separates from the vehicle body sheet metal 11, thereby improving the separation efficiency and effectiveness of the laminated glass 121.

[0112] Furthermore, the thickness of the laminated glass 121 that rescuers need to break outside the vehicle is significantly reduced, making it easier for the laminated glass 121 to detach from the vehicle body panel 11, thus improving rescue efficiency. In addition, in emergency situations, the laminated glass 121 can break at the expected location, which not only improves the vehicle's safety and reliability but also makes it easier to replace the broken laminated glass 121 later, thus improving the replacement efficiency of the laminated glass 121.

[0113] For example, please refer to Figures 5 to 7 In any given case, when the first glass 1211 is the outer pane and the second glass 1212 is the inner pane, the base 21 is connected to the second glass 1212, and the second glass 1212 has a first clearance hole 12121, while the intermediate layer 1213 has a second clearance hole 12131. Both the first clearance hole 12121 and the second clearance hole 12131 are positioned corresponding to the position of the striking pin 25. Thus, when the first clearance hole 12121 and the second clearance hole 12131 are provided, the striking pin 25 can easily pass through them to shatter the first glass 1211.

[0114] Of course, as an alternative, the second glass 1212 and the intermediate layer 1213 may not need to have clearance holes corresponding to the position of the striking pin 25. When the impact force of the striking pin 25 is large, it can still pass through the second glass 1212 and the intermediate layer 1213, thereby causing the first glass 1211 to shatter.

[0115] It should be noted that, in this embodiment, the corresponding position of the first clearance hole 12121 and the striker 25 means that, along the thickness direction of the laminated glass 121, the projection of the striker 25 is located within the outline area of ​​the first clearance hole 12121. Similarly, the corresponding position of the second clearance hole 12131 and the striker 25 means that, along the thickness direction of the laminated glass 121, the projection of the striker 25 is located within the outline area of ​​the second clearance hole 12131.

[0116] The shapes of the first clearance hole 12121 and the second clearance hole 12131 can be flexibly adjusted and set according to actual needs.

[0117] The first clearance hole 12121 and the second clearance hole 12131 can both be set as closed holes, specifically, for example, circular holes, with a diameter of ≥6mm, specifically 6mm, 8mm or 10mm, etc.

[0118] Of course, both the first clearance hole 12121 and the second clearance hole 12131 can be configured as non-closed holes.

[0119] Please see Figures 5 to 9 In any given example, connector 122 and second glass 1212 are connected to the same side of first glass 1211 and spaced apart. Thus, when the area of ​​first glass 1211 other than connector 122 is shattered by the blasting device 20, the main structure of laminated glass 121 can be separated from the vehicle body sheet 11, and is no longer connected to the edge of first glass 1211 where connector 122 is located. Furthermore, the shattered first glass 1211 and second glass 1212 are connected by an interlayer 1213, ensuring that the large number of fragments generated after the first glass 1211 is damaged will not become a source of injury, providing a safety barrier for personnel.

[0120] The main structure of the laminated glass 121 refers to the area on the laminated glass 121 other than the area where the connector 122 is provided.

[0121] For example, the shortest distance between the connector 122 and the second glass 1212 is ≥0, and the specific shortest distance is, for example, 0, 0.5mm, 1mm or 2mm.

[0122] Please see Figure 8 or Figure 9For example, when the first glass 1211 is the outer pane and the second glass 1212 is the inner pane, the base 21 is connected to the extension 1214, and the base 21, connector 122, and second glass 1212 are all located on the same side of the first glass 1211. The portion of the first glass 1211 opposite to the impact pin 25 is spaced apart from the connector 122. Therefore, when the laminated glass 121 is subjected to the impact pin 25 of the blasting device 20, the impact pin 25 can easily shatter the area of ​​the first glass 1211 outside the connector 122, without being affected by the connector 122 and thus unable to shatter. The portion of the first glass 1211 corresponding to the connector 122 is still connected to the body sheet metal 11 by the connector 122. After the area of ​​the first glass 1211 outside the connector 122 is shattered, the main structure of the laminated glass 121 can be separated from the body sheet metal 11. Furthermore, the shattered first glass 1211 and the second glass 1212 are connected together by an intermediate layer 1213, ensuring that the large number of fragments generated after the first glass 1211 is damaged will not become a source of harm, thus providing a safety barrier for personnel.

[0123] Please see Figures 10 to 14 For example, when the first glass 1211 is the inner pane and the second glass 1212 is the outer pane, the base 21 is connected to the first glass 1211, and both the base 21 and the connector 122 are located on the side of the first glass 1211 away from the second glass 1212. The portion of the first glass 1211 opposite to the impact pin 25 is spaced apart from the connector 122. Therefore, when the laminated glass 121 is subjected to the impact pin 25 of the blasting device 20, the impact pin 25 can easily break the area of ​​the first glass 1211 other than the connector 122, without being affected by the connector 122 and thus unable to break it. The portion of the first glass 1211 corresponding to the connector 122 is still connected to the body sheet metal 11 by the connector 122. After the area of ​​the first glass 1211 other than the connector 122 is broken, the main structure of the laminated glass 121 can be separated from the body sheet metal 11. Furthermore, the shattered first glass 1211 and the second glass 1212 are connected together by an intermediate layer 1213, ensuring that the large number of fragments generated after the first glass 1211 is damaged will not become a source of harm, thus providing a safety barrier for personnel.

[0124] Based on the aforementioned embodiments, the arrangement position of the base 21 on the first glass 1211 is not limited, and can be flexibly adjusted and set according to actual needs, as long as the relative part of the first glass 1211 and the striker 25 are spaced apart from the connector 122.

[0125] Please see Figure 13 and Figure 14 For example, both the base 21 and the connector 122 are connected to the extension 1214. The base 21 is closer to the center of the laminated glass 121 than the connector 122.

[0126] Of course, please see Figure 11 and Figure 12 Alternatively, the base 21 may not need to be provided in the extension 1214. For example, the projection of the base 21 on the first glass 1211 along the thickness direction of the laminated glass 121 is located within the range of the projection of the second glass 1212 on the first glass 1211 along the thickness direction of the laminated glass 121.

[0127] Alternatively, the projection of the base 21 onto the first glass 1211 along the thickness direction of the laminated glass 121 at least partially overlaps with the projection of the second glass 1212 onto the first glass 1211 along the thickness direction of the laminated glass 121.

[0128] In any of the foregoing embodiments, the connection between the base 21 and the laminated glass 121 may include, but is not limited to, various methods such as bonding, welding or injection molding, as long as a fixed connection between the base 21 and the laminated glass 121 can be achieved. The specific connection method can be flexibly adjusted and set according to actual needs.

[0129] Please see Figure 3 and Figure 6 For example, the blasting device 20 also includes a locking component 23. The locking component 23 is disposed between the drive mechanism 22 and the firing pin 25. That is, the drive mechanism 22 is connected to the firing pin 25 through the locking component 23. The locking component 23 is rotatably disposed on the base 21, and the locking component 23 has a locked position and an unlocked position. The locking component 23 can be rotated to adjust from the locked position to the unlocked position. When the locking component 23 is in the locked position, the locking component 23 locks the drive mechanism 22, at which time the drive mechanism is not triggered, and the firing pin 25 cannot be ejected; when the locking component 23 is in the unlocked position, the locking component 23 unlocks the drive mechanism 22, the drive mechanism 22 is triggered, and the drive mechanism 22 acts accordingly on the locking component 23 and the firing pin 25, causing the firing pin 25 to eject, thereby shattering the laminated glass 121.

[0130] For example, the base 21 includes a fixing sleeve 211 and a positioning plate 212. One end of the fixing sleeve 211 is connected to the laminated glass 121, and the positioning plate 212 is disposed inside the fixing sleeve 211 and connected to the fixing sleeve 211. The positioning plate 212 has a through hole 2121 and an unlocking hole 2122 communicating with the through hole 2121.

[0131] The locking assembly 23 includes a sliding insert 231 and a rotating member 232. The sliding insert 231 is rotatably disposed within the fixed sleeve 211 and is located between the positioning plate 212 and the laminated glass 121. A striking pin 25 is connected to the end of the sliding insert 231 near the laminated glass 121. The driving mechanism 22 includes an elastic member 221, which is connected between the sliding insert 231 and the positioning plate 212. The rotating member 232 passes through the through hole 2121 and is connected to the sliding insert 231. The rotating member 232 is located on the side of the positioning plate 212 opposite to the laminated glass 121.

[0132] The rotating component 232 can rotate relative to the positioning plate 212. When the rotating component 232 is positioned opposite the unlocking hole 2122, the rotating component 232 can completely pass through the unlocking hole 2122, and the locking component 23 is in the unlocked position. When the rotating component 232 is misaligned with the unlocking hole 2122, the positioning plate 212 can abut against the positioning rotating component 232, and the locking component 23 is in the locked position.

[0133] For example, the elastic element 221 may include, but is not limited to, a spring or an elastic strip. In this embodiment, the elastic element 221 is specifically a spring, which is sleeved on the outside of the sliding insert 231. The outer wall of the sliding insert 231 has a protrusion 2311, which is provided, for example, around the outer periphery of the sliding insert 231. The opposite ends of the elastic element 221 abut against the protrusion 2311 and the positioning plate 212. Thus, when the locking component 23 is in the locked position, the elastic element 221 is in a compressed state, and the opposite ends of the elastic element 221 abut against and are positioned with respect to the protrusion 2311 and the positioning plate 212, respectively; when the locking component 23 is in the unlocked position, the elastic element 221 is triggered, and the elastic element 221 drives the striking pin 25 and the sliding insert 231 to move toward the laminated glass 121 through its own elastic force, thereby breaking the laminated glass 121.

[0134] Please continue reading. Figure 3 and Figure 6To improve safety and prevent accidental activation, the locking assembly 23, for example, further includes a limiting block 233. The limiting block 233 is connected to the end of the rotating member 232 and is located on the side of the positioning plate 212 opposite to the laminated glass 121. The positioning plate 212 has a stop member 2123 on the side opposite to the laminated glass 121, which abuts against the limiting block 233. When the rotating member 232 rotates and causes the limiting block 233 to act on the stop member 2123 with a pressure greater than a preset value, the limiting block 233 separates from the rotating member 232. When the limiting block 233 is not separated from the rotating member 232, and the rotating member 232 is positioned opposite the unlocking hole 2122, the positioning plate 212 abuts against the positioning limiting block 233. Thus, when it is necessary to unlock the locking component 23, the rotating member 232 is first rotated, causing the limiting block 233 to act on the blocking member 2123 with a pressure greater than the preset value, causing the limiting block 233 to separate from the rotating member 232. Then, the rotating member 232 is rotated to a position opposite to the unlocking hole 2122, thereby unlocking the locking component 23. Conversely, when the limiting block 233 is not separated from the rotating member 232, even if the rotating member 232 rotates to a position opposite to the unlocking hole 2122, the positioning plate 212 abuts against the positioning limiting block 233, thereby indirectly positioning the rotating member 232, and the locking component 23 will still not be unlocked. It can be seen that by adding the limiting block 233 and the blocking component 2123, the blasting device 20 has the function of preventing accidental opening. That is, a certain force is required to break the connection between the rotating component 232 and the limiting block 233 before the rotating component 232 can be adjusted to the unlocked position and the locking component 23 can be unlocked. The safety is improved and accidental activation can be effectively prevented.

[0135] It should be noted that the preset pressure is not limited to 5N, 10N, 15N or 20N, etc., and can be flexibly adjusted and set according to actual needs. No limit is set here.

[0136] It should be noted that the "limiting block 233" in this embodiment can be a part of the "rotating component 232", that is, the "limiting block 233" and the "other parts of the rotating component 232" are integrally formed; or it can be an independent component that can be separated from the "other parts of the rotating component 232", that is, the "limiting block 233" can be manufactured independently and then combined with the "other parts of the rotating component 232" to form a whole.

[0137] For example, the limiting block 233 and the rotating component 232 can be integrally molded by injection molding, or they can be connected by adhesive bonding or snap-fit. In this embodiment, the limiting block 233 and the rotating component 232 are preferably integrally molded from plastic. This not only facilitates manufacturing, but also allows the limiting block 233 and the rotating component 232 to separate by applying a pressure greater than a preset value to make the limiting block 233 press against the blocking component 2123.

[0138] For example, two limit blocks 233 are provided, and the two limit blocks 233 are connected to the opposite ends of the rotating member 232. Two abutment members 2123 are also provided, and the two abutment members 2123 are set one-to-one with the two limit blocks 233. In this way, before the locking component 23 can be unlocked, the rotating member 232 needs to be rotated so that both limit blocks 233 are separated from the rotating member 232. This improves the safety performance compared to using a single limit block 233.

[0139] Based on the aforementioned embodiment, the two blocking members 2123 are symmetrically arranged about the central axis of the base 21.

[0140] For example, the stop member 2123 is configured as a stop block, and the stop block has a first end and a second end opposite to each other along the rotation direction of the rotating member 232. The first end has a relief recess 21231, which can avoid the rotating member 232, and the first end abuts and engages with the limiting block 233; the second end abuts and engages with the rotating member 232; the unlocking hole 2122 is located in the area between the two stop members 2123. Thus, before unlocking the locking assembly 23, the rotating member 232 is rotated in the first direction, causing both limiting blocks 233 to move towards their respective first ends. Since the avoidance recess 21231 can avoid the rotating member 232, and the limiting blocks 233 can abut against the first ends, when the pressure exerted by the rotating member 232 on the abutment 2123 exceeds a preset value, the limiting blocks 233 and the rotating member 232 can be smoothly separated. Then, the rotating member 232 is rotated in the second direction, causing it to move towards the second end. When the rotating member 232 rotates to a position opposite to the unlocking hole 2122, the locking assembly 23 is unlocked. Therefore, rotating the rotating member 232 first in the first direction and then in the second direction—that is, rotating in two different directions—is necessary to unlock the locking assembly 23. This effectively prevents accidental glass breakage due to human error, thus improving safety.

[0141] In this embodiment, one of the first direction and the second direction is, for example, clockwise and the other is counterclockwise. Preferably, the first direction is, for example, clockwise and the second direction is, for example, counterclockwise.

[0142] Based on the aforementioned embodiments, during the unlocking operation of the locking component 23, the rotation angle range of rotating member 232 from the second end to the first end along the first direction is, for example, 50°~135°, specifically, 50°, 60°, 70°, 90°, 100°, 120°, or 135°. The rotation angle range of rotating member 232 from the first end to the unlocking hole 2122 along the second direction is, for example, ≥30°, specifically, 30°, 35°, 40°, or 45°, etc.

[0143] For example, the striking pin 25 may be made of metal materials, such as hardened stainless steel (HRC50-55) or tungsten steel containing 16% or other metal materials. The striking pin 25 has a tapered tip design and a stroke of, for example, 2mm to 10mm, specifically 5mm to 8mm, which can be flexibly adjusted and set according to actual needs to break the laminated glass 121.

[0144] For example, the firing pin 25 is fixedly installed on the sliding insert 231 by various means including but not limited to bonding, snap-fitting, riveting, welding or integral injection molding.

[0145] For example, the drive mechanism 22 in this embodiment specifically uses a spring. The spring is, for example, a stainless steel compression spring, with a preload of, for example, ≥20N when the locking assembly 23 is in the locked position.

[0146] For example, the surface of the spring is plated with a protective layer such as zinc to prevent rust, extend service life, and ensure product performance.

[0147] Please see Figure 4 and Figure 7 For example, the blasting device 20 also includes a protective cover 24, which is detachably connected to the other end of the fixing sleeve 211. Thus, when the protective cover 24 is installed at the other end of the fixing sleeve 211, it prevents the rotating part 232 from being exposed, preventing accidental operation and improving safety. When unlocking is required, the protective cover can be removed from the fixing sleeve 211.

[0148] Specifically, in this embodiment, the protective cover is connected to the fixing sleeve 211 by a snap-fit ​​mechanism. Furthermore, when the protective cover needs to be removed, a force of ≥20N must be applied to it. This improves safety and prevents accidental contact.

[0149] For example, the outer surface of the protective cover may be marked with various symbols such as "blasting" to serve as a warning.

[0150] For example, the protective cover may be made of engineering plastics, such as PA66 with 30% glass fiber. This gives the protective cover good impact resistance and flame retardant properties.

[0151] Please refer to the following: Figure 6 For example, the locking assembly 23 further includes an electrically controlled drive 234 and a locking member 235 disposed between the rotating member 232 and the sliding insert 231. The electrically controlled drive 234 is mounted on the rotating member 232 and connected to the locking member 235; the electrically controlled drive 234 can drive the locking member 235 to move to a locked position or a released position. Specifically, when the locking member 235 is in the locked position, the locking member 235 is fixedly connected to the sliding insert 231; when the locking member 235 is in the released position, the locking member 235 releases the sliding insert 231. Thus, when the electronically controlled drive unit 234 does not receive the unlocking control command, the locking member 235 is connected and fixed to the sliding insert 231, thereby realizing the connection and fixation between the rotating member 232 and the sliding insert 231, and thus playing the role of locking the striker 25; when the electronically controlled drive unit 234 receives the unlocking control command, it can drive the locking member 235 to move to the loosened position, thereby triggering the drive mechanism 22. The drive mechanism 22 causes the sliding insert 231 and the striker 25 to move towards the laminated glass 121, thereby breaking the laminated glass 121.

[0152] Specifically, in this embodiment, the electronically controlled drive unit 234 is electrically connected to the vehicle system. When the vehicle system detects an emergency, it can issue an unlocking control command. The electronically controlled drive unit 234 performs an unlocking action according to the unlocking control command, that is, it drives the locking member 235 to move to the loosened position, thereby triggering the drive mechanism 22. The drive mechanism 22 causes the sliding insert 231 and the striking pin 25 to move towards the laminated glass 121, thereby breaking the laminated glass 121.

[0153] Therefore, the blasting device 20 in this embodiment can not only unlock the locking component 23 by rotating the rotating member 232, but also unlock the locking component 23 in an automatic mode, such as under the control of the vehicle system, which can improve safety and flexibility.

[0154] For example, the electrically controlled drive component 234 may include, but is not limited to, an electromagnet. The locking component 235 may include, but is not limited to, a pin. For example, when the electromagnet is energized, the pin retracts and disengages from the sliding insert 231, thereby releasing the sliding insert 231 and unlocking the locking component 23.

[0155] In one embodiment, see Figure 14 Furthermore, the blasting device 20 in this example can be installed on a single layer of tempered glass to achieve the blasting action of the single layer of tempered glass.
