[0042] As Figures 1 to 4 shown in the first aspect, the utility model embodiment provides a kind of window breaking device, and window breaking device includes:

[0043] Punch pin 1, punch pin 1 includes needle body 11 and the first limit protrusion 12 of protruding from needle body 11.

[0047] As can be seen from the above embodiment, in the embodiment of the utility model, because the guide support 2 includes the guide cavity 21 and the contact window 22 communicated with the guide cavity 21, the striker 1 is movably connected in the guide cavity 21, so that the striker 1 can move relative to the guide cavity 21. And because the driving assembly 3 includes the driving shell 31 and the driving piece 32, the driving piece 32 and the driving shell 31 are drivingly connected, the guide support 2 is embedded in the driving shell 31, the inner wall of the driving shell 31 includes the second limiting protrusion 311, so that the driving shell 31 and the guide support 2 can be driven to move relatively by the driving assembly 3, and then the striker 1 is driven to move relatively by the guide support 2. In this way, before breaking the window, the striker 1 can be in the first state, so that the first limiting protrusion 12 protrudes from the contact window 22 and contacts the second limiting protrusion 311, and then the needle body 11 is limited in the guide cavity 21 by the second limiting protrusion 311. When the striker 1 needs to break the window, the driving piece 32 can drive the driving shell 31 to move in the first direction, and when the end of the guide support 2 abuts against the vehicle window glass, the relative movement between the guide support 2 and the driving shell 31 occurs, the guide support 2 drives the striker 1 to displace, and then the striker 1 is in the second state, so that the first limiting protrusion 12 and the second limiting protrusion 311 are separated, the end of the needle body 11 protrudes from the guide cavity 21, and the window breaking is completed. In summary, in the window breaking device provided by the embodiment of the utility model, the relative position between the first limiting protrusion 12 and the second limiting protrusion 311 can be changed to realize the movement of window breaking, the whole structure is simple, easy to install, and when the vehicle is in an abnormal environment and the door 40 cannot be opened, the window breaking device can break the window, the whole process can be automatically completed, the success rate of window breaking can be ensured, and the safety performance of the vehicle is improved.

[0048] In the above embodiment, the striker 1 is in a rod-shaped structure, and the top of the striker 1 is in a sharp needle-shaped structure, which is beneficial to improve the local impact force when breaking the window. The striker 1 includes the needle body 11 and the first limiting protrusion 12 protruding from the needle body 11, and the first limiting protrusion 12 can be a flange structure, a circular truncated cone structure or other protruding structures, so that the first limiting protrusion 12 has sufficient limiting surfaces. It should be noted that the striker 1 can be made of tungsten steel, titanium alloy, molybdenum alloy or other materials with high strength, and the embodiment of the utility model does not limit this.

[0049] The guide support 2 is a shell structure with both ends open. The guide support 2 can be a cylindrical structure, a square cylindrical structure or other cylindrical structure. For example, the guide support 2 can be a cylindrical structure with one end open. A guide hole is formed at the end of the guide support 2 which is not open, so as to facilitate the guide pin 1 to extend out of the guide hole. The inside of the guide support 2 is a guide cavity 21. A through slot structure is formed at the side of the end of the guide support 2 which is open, forming a contact window 22. The guide pin 1 can be movably connected in the guide cavity 21 by clamping, embedding or other methods. The movably connected here can be understood as non-fixed connection, or can be understood as contact connection, so that the relative position between the guide pin 1 and the guide cavity 21 can change under the action of external force.

[0050] The driving assembly 3 includes a driving shell 31 which can be a cylindrical shell structure, a square shell structure or other shell structure. The driving shell 31 is a shell structure with one end open. The guide support 2 is embedded in the driving shell 31 from the end of the driving shell 31 which is open. The gap should be provided between the outer wall of the guide support 2 and the inner wall of the driving shell 31, so that the guide support 2 can move relative to the driving shell 31 under the action of external force. It should be noted that the guide support 2 at least partially extends from the end of the driving shell 31 which is open, so as to ensure that the guide support 2 can first contact the window glass, and then facilitate the change of the relative position between the guide support 2 and the guide pin 1 under the action of force. The second limiting protrusion 311 is arranged on the inner wall of the driving shell 31. The second limiting protrusion 311 can be a boss structure at the variable diameter of the inner wall of the driving shell 31, or a protruding structure on the inner wall of the driving shell 31, or other protruding parts on the inner wall of the driving shell 31. The embodiments of the utility model do not make limitation in this regard. The driving member 32 included in the driving assembly 3 can be a motor gear structure, a cylinder push rod structure or other driving structure which can provide linear motion. The embodiments of the utility model do not make limitation in this regard.

[0051] In some embodiments, the driving shell 31 includes a movable inner cavity which is separated into a first inner cavity 313 and a second inner cavity 314 by a partition 312. The guide support 2 is movably connected in the first inner cavity 313. The needle body 11 includes a needle head 13 and a needle seat 14. The needle head 13 and the needle seat 14 are located at two opposite ends of the needle body 11 in the first direction. The needle body 11 penetrates through the partition 312. The needle seat 14 is located in the second inner cavity 314. In the first state, the needle seat 14 is away from the partition 312. The needle head 13 is located in the first inner cavity 313. In the second state, the needle seat 14 is close to the partition 312. The needle head 13 extends out of the first inner cavity 313. The first direction is indicated by Y in the figure. Figure 4

[0052] ​In this embodiment, a through hole can be formed on the partition plate 312, and the needle body 11 passes through the through hole. The cross-sectional area of the through hole is less than or equal to the cross-sectional area of the needle seat 14, so that the limit at the partition plate 312 is formed. Since the needle seat 14 is away from the partition plate 312 in the first state, and the needle head 13 is located in the first inner cavity 313 in the second state, the limit of the critical point between the two states can be formed by the partition plate 312, so that the needle body 11 is prevented from being ejected from the partition plate 312 as a whole, and the stroke of the needle body 11 moving in the first direction is formed by the through hole formed on the partition plate 312.

[0053] In some embodiments, the window breaking device further comprises a first elastic member 4 sleeved on the striker 1, and the first limiting protrusion 12 is located at one end close to the needle head 13. The first elastic member 4 is located between the first limiting protrusion 12 and the partition plate 312. In the first state, the first elastic member 4 is in a compressed deformation state, and in the second state, the first elastic member 4 is in a recovery deformation state.

[0054] In this embodiment, since the first elastic member 4 is located between the first limiting protrusion 12 and the partition plate 312, when the distance between the first limiting protrusion 12 and the partition plate 312 changes, the elastic deformation state of the first elastic member 4 also changes. The first elastic member 4 can be any one of a rubber elastic body, a spring, a silica gel elastic body, etc. The utility model embodiment is not limited to this, and the following will take the first elastic member 4 as a spring as an example for description. Before breaking the window, the striker 1 can be in the first state, so that the first limiting protrusion 12 protrudes from the contact window 22 and contacts the second limiting protrusion 311, so that the needle body 11 is located in the guide cavity 21 under the limiting action of the second limiting protrusion 311. In this state, the spring is compressed between the first limiting protrusion 12 and the partition plate 312, and is in a compressed deformation state. When the striker 1 needs to break the window, the driving member 32 drives the driving shell 31 to move in the first direction. When the end of the guide bracket 2 abuts against the vehicle window glass, the guide bracket 2 is subjected to the force in the opposite direction of the first direction applied by the vehicle window glass, so that the guide bracket 2 and the driving shell move relatively, the guide bracket 2 drives the striker 1 to displace, and then the striker 1 is in the second state, so that the first limiting protrusion 12 and the second limiting protrusion 311 are separated, and the first limiting protrusion 12 is separated from the restriction of the guide bracket 2. Then, under the action of the elastic force generated in the process of the spring recovering, the needle seat 14 approaches the partition plate 312, and the needle head 13 protrudes from the first inner cavity 313, and the window breaking is completed. In this process, due to the elastic force of the spring, the striker 1 has sufficient impact pressure.

[0055] For example, the maximum pressure that the vehicle window glass can withstand is 108 Pa, i.e. the pressure generated by the breaking window device is greater than 10 8 Pa, i.e. the purpose of breaking the vehicle window glass 50 can be achieved. Based on this, taking the length (△X) of the spring in the free state as 20 mm, the wire shear modulus (G) of the spring as 65 Mn (spring 1 material) G = 80000 MPa, the spring wire diameter (D) as 4.4 mm, the spring wire diameter (d) as 1 mm, and the effective number of turns (N) of the spring as 13 as examples, the spring force (F) of the spring is equal to the elastic coefficient (k) multiplied by the spring deformation variable △X, wherein ， Pa, i.e. the pressure generated by the breaking window device is greater than 10 It can be calculated that the spring force is 63 N. In the case that the cross-sectional area of the needle head 13 of the striker 1 is 0.0314 mm2, the pressure generated by the striker 1 hitting the vehicle window glass is 2×10 9 Pa. Based on the maximum pressure that the vehicle window glass can withstand is 10 8 Pa, therefore the spring force can break the vehicle window glass 50, and thus the breaking window effect of the striker 1 can be ensured.

[0056] In some embodiments, the first inner cavity 313 further comprises a limiting plate 315, which is located between the partition plate 312 and the guide bracket 2; the breaking window device further comprises a second elastic member 5, which is arranged between the end of the guide bracket 2 towards the first inner cavity 313 and the limiting plate 315, and the first elastic member 4 and the needle body 11 both pass through the second elastic member 5; in the first state, the second elastic member 5 is in a compressed state, and in the second state, the second elastic member 5 is in a recovered deformation state.

[0057] In this embodiment, the second elastic member 5 can be any one of a rubber elastic body, a spring, a silica gel elastic body, etc., and the following will be described by taking the second elastic member 5 as a spring. Since the second elastic member 5 is arranged between the end of the guide bracket 2 towards the first inner cavity 313 and the limiting plate 315, and the first elastic member 4 and the needle body 11 both pass through the second elastic member 5, when the guide bracket 2 is subjected to the force in the opposite direction of the first direction applied by the vehicle window glass, the relative movement between the guide bracket 2 and the driving housing 31 occurs, so that the distance between the end of the guide bracket 2 towards the first inner cavity 313 and the limiting plate 315 changes, and further the elastic deformation state of the second elastic member 5 between the end of the guide bracket 2 towards the first inner cavity 313 and the limiting plate 315 changes. The movement principle of the second elastic member 5 is consistent with that of the first elastic member 4, and the embodiment of the utility model will not be described here. In this way, under the action of the second elastic member 5, not only can the effect of the guide bracket 2 being subjected to the force in the opposite direction of the first direction applied by the vehicle window glass be more obvious, but also the impact force of the striker 1 can be larger under the common elastic force of the first elastic member 4 and the second elastic member 5, and the breaking effect of the striker 1 is further ensured.

[0058] As to the type of the driving member 32, in one possible implementation, the driving member 32 comprises a driving motor 321 and a driving gear 322; the driving shaft of the driving motor 321 is connected with the driving gear 322, and the outer surface of the driving housing 31 is provided with a rack 316, and the driving gear 322 is engaged with the rack 316.

[0059] In this embodiment, the driving shaft of the driving motor 321 can be coaxially connected with the driving gear 322. Since the driving shaft of the driving motor 321 is connected with the driving gear 322, and the outer surface of the driving housing 31 is provided with the rack 316, and the driving gear 322 is engaged with the rack 316, when the driving motor 321 rotates, the driving gear 322 can rotate, and further drive the driving housing 31 to move in the first direction, and further the whole breaking process can be automatically completed, and the success rate of breaking is ensured.

[0060] As to the type of the driving member 32, in another possible implementation, the driving member 32 comprises a push rod and a cylinder; one end of the push rod is connected with the piston rod of the cylinder, and the other end of the push rod is connected with the end of the driving housing 31 in the first direction.

[0061] In this embodiment, since the driving member 32 comprises the push rod and the cylinder; one end of the push rod is connected with the piston rod of the cylinder, and the other end of the push rod is connected with the end of the driving housing 31 in the first direction, the extension and retraction of the piston rod of the cylinder can drive the push rod to move, so that the push rod drives the driving housing 31 to move in the first direction, and the whole breaking process can also be automatically completed, and the success rate of breaking is ensured.

[0062] Need to explain, no matter the driving member 32 includes the drive motor 321 and the drive gear 322, or the driving member 32 includes the push rod and the cylinder, can realize the automation of the window breaking process, and facilitate the automation control of the whole window breaking process, so that the whole window breaking process is safe and controllable, and the accuracy is improved.

[0063] From the above embodiment, in the embodiment of the utility model, because the guide support 2 includes the guide cavity 21 and the contact window 22 communicated with the guide cavity 21, the striker 1 is movably connected in the guide cavity 21, therefore can make the striker 1 relative motion with the guide cavity 21. And because the driving assembly 3 includes the driving shell 31 and the driving member 32, the driving member 32 and the driving shell 31 drive connection, the guide support 2 is embedded in the driving shell 31, the inner wall of the driving shell 31 includes the second limit protrusion 311, therefore can drive the driving shell 31 and the guide support 2 relative motion through the driving assembly 3, and then drive the striker 1 relative motion through the guide support 2. In this way, before breaking the window, the striker 1 can be in the first state, so that the first limit protrusion 12 extends from the contact window 22 and contacts the second limit protrusion 311, and then the needle body 11 is limited in the guide cavity 21 under the action of the second limit protrusion 311. When the striker 1 needs to break the window, the driving member 32 drives the driving shell 31 to move in the first direction, and when the end of the guide support 2 abuts against the vehicle window glass, the guide support 2 and the driving shell move relative to each other, the guide support 2 drives the striker 1 to displace, and then the striker 1 is in the second state, finally the first limit protrusion 12 and the second limit protrusion 311 are separated, the end of the needle body 11 extends out of the guide cavity 21, and the window breaking is completed. In summary, in the window breaking device provided by the embodiment of the utility model, the movement of breaking the window can be realized by changing the relative position between the first limit protrusion 12 and the second limit protrusion 311, the whole structure is simple, easy to install, and when the vehicle is in an abnormal environment and the door 40 cannot be opened, the window breaking device can break the window, the whole process can be automatically completed, the success rate of window breaking can be ensured, and the safety performance of the vehicle is improved.

[0064] In a second aspect, as Figure 5 shown, the utility model embodiment still provides a kind of vehicle window breaking escape system, which includes control module 20, signal input module 30 and the window breaking device 10 of any one of the first aspect embodiment;Signal input module 30, window breaking device 10 respectively and control module 20 are electrically connected, wherein signal input module 30 includes air bag trigger signal input end 301, cloud signal input end 302 and artificial signal input end 303, control module 20 is used to control window breaking device 10 to operate based on the electrical signal input of signal input module 30.

[0065] As can be seen from the above embodiments, since the vehicle window breaking escape system comprises the window breaking device 10, and the window breaking device 10 has the beneficial effects of simple structure, easy installation, and the window breaking can be realized through the window breaking device 10 when the vehicle is in an abnormal environment and the door 40 cannot be opened, the whole process can be automatically completed, and the success rate of window breaking can be ensured, so that the vehicle window breaking escape system also has the effects of low preparation cost, easy installation, and the success rate of window breaking can be ensured. Since the signal input module 30 and the window breaking device 10 are respectively electrically connected with the control module 20, the signal input module 30 comprises the airbag triggering signal input end 301, the cloud signal input end 302, and the manual signal input end 303, and the control module 20 is used for controlling the window breaking device 10 to operate based on the electrical signal input by the signal input module 30, so that the electrical signal can be input to the control module 20 through the signal input module 30, and the window breaking device 10 is controlled to break the window through the control module, so that the whole window breaking process is safe and controllable, and is not affected by the signal input environment, that is, no matter what scene the driver and the passenger are in, the window breaking can be performed when the window breaking is needed, and the reliability of the vehicle window breaking escape system can be ensured.

[0066] In addition, it should be noted that the manual signal input end 303 can be understood as an electrical signal actively triggered by the driver and the passenger through a key type, a dial type switch or the like active switch. However, when the vehicle is in a working condition environment such as a serious collision or falling into water, the driver and the passenger cannot actively trigger the electrical signal, and the control electrical signal can be provided through the airbag triggering signal input end and the cloud signal input end 302. Not only can the driver and the passenger ensure that the window breaking action can be triggered when the window breaking operation is needed in any scene, but also the cost of breaking the window glass caused by triggering the window breaking operation when a slight collision occurs can be avoided, and the reliability of the window breaking operation is further ensured.

[0068] In this embodiment, since the vehicle window glass 50 is installed on the vehicle door 40, the distance between the position where the breakage device 10 is installed on the vehicle door 40 and the bottom edge of the vehicle window glass 50 in the second direction when the bottom edge of the vehicle window glass 50 is at a preset distance from the position where the needle 13 included in the striker 1 is in a relative position to the vehicle window glass 50 is a distance between the position where the breakage device 10 is installed on the vehicle door 40 and the bottom edge of the vehicle window glass 50 in the second direction, wherein the first position is on the vehicle window glass 50 and is 15 mm away from the bottom edge of the vehicle window glass 50, and the second direction is the direction of the width of the vehicle, so not only can the breakage device 10 be installed in the limited space of the vehicle door 40, that is, the installation of the breakage device 10 in the limited space of the vehicle door 40 is ensured, but also the normal operation of the breakage device 10 is ensured, and since the position on the vehicle window glass 50 that is 15 mm away from the bottom edge of the vehicle window glass 50 is the weak point of the vehicle window glass 50, the striker 1 can directly impact the weak point of the vehicle window glass 50, thereby ensuring the breakage effect. It should be noted that the distance between the position where the breakage device 10 is installed on the vehicle door 40 and the bottom edge of the vehicle window glass 50 in the second direction should be greater than the size of the driving housing 31 in the extension direction of the striker 1, for example, when the distance between the position where the breakage device 10 is installed on the vehicle door 40 and the bottom edge of the vehicle window glass 50 in the second direction is 45 mm, the size of the driving housing 31 in the extension direction of the striker 1 can be 35 mm, for example, when the distance between the position where the breakage device 10 is installed on the vehicle door 40 and the bottom edge of the vehicle window glass 50 in the second direction is 40 mm, the size of the driving housing 31 in the extension direction of the striker 1 can be 32 mm, that is, the greater the distance between the position where the breakage device 10 is installed on the vehicle door 40 and the bottom edge of the vehicle window glass 50 in the second direction, the greater the size of the driving housing 31 in the extension direction of the striker 1, so that the breakage device 10 can be installed in the limited space of the vehicle door 40, and the striker 1 can normally impact the weak point of the vehicle window glass 50. In addition, in this embodiment, the sizes of different vehicle models are different, so the distance between the position where the breakage device 10 is installed on the vehicle door 40 and the bottom edge of the vehicle window glass 50 in the second direction is also different, that is, the position where the breakage device 10 is installed on the vehicle door 40 is also different for different vehicle models. In addition, the width direction of the vehicle in the above embodiments can be understood as the extension direction of the line between the two side doors of the vehicle, and the second direction is the direction indicated by Z in Figure 4 .

[0069] In some embodiments, as Figure 8As shown, the vehicle further comprises a mounting bracket 60, the door 40 comprises a door window outer reinforcing plate 401; the door window outer reinforcing plate 401 comprises a first mounting surface and a second mounting surface with an included angle, the mounting bracket 60 comprises a first mounting plate 601 and a second mounting plate 602, the plane where the first mounting plate 601 is located intersects with the plane where the second mounting plate 602 is located, the first mounting plate 601 is mounted on the first mounting surface, the second mounting plate 602 is mounted on the second mounting surface, and the plane where the first mounting plate 601 is located faces the vehicle window glass; the drive housing 31 is mounted on the first mounting plate 601, the driving member 32 is mounted on the second mounting plate 602, and the extension direction of the striker 1 and the plane where the vehicle window glass is located have an included angle, and the included angle is a right angle.

[0070] In this embodiment, since the door window outer reinforcing plate 401 comprises a first mounting surface and a second mounting surface with an included angle, the mounting bracket 60 comprises a first mounting plate 601 and a second mounting plate 602, the plane where the first mounting plate 601 is located intersects with the plane where the second mounting plate 602 is located, the first mounting plate 601 is mounted on the first mounting surface, the second mounting plate 602 is mounted on the second mounting surface, and the plane where the first mounting plate 601 is located faces the vehicle window glass 50, the drive housing 31 is mounted on the first mounting plate 601, and the driving member 32 is mounted on the second mounting plate 602, the quick installation of the breakage device 10 can be realized through the mounting bracket 60, the influence of the installation of the breakage device 10 on the strength of the door 40 is reduced, and it can be ensured that after installation, the striker 1 of the breakage device 10 can face the vehicle window glass 50. Since the extension direction of the striker 1 and the plane where the vehicle window glass 50 is located have an included angle, and the included angle is a right angle, the striker 1 can be perpendicular to the vehicle window glass 50, the vehicle window glass 50 and the striker 1 are in vertical force, the stress of the vehicle window glass 50 under the striker 1 is increased, and the reliability of the striker 1 in breaking the window is further ensured.

[0071] In some embodiments, the vehicle further comprises a backup power supply 70; the backup power supply 70 is arranged on the door 40, and the backup power supply 70 and the driving member 32 are electrically connected.

[0072] In this embodiment, since the backup power supply 70 is arranged on the door 40, and the backup power supply 70 and the driving member 32 are electrically connected, when the electrical connection between the driving member 32 and the power supply of the vehicle fails after the vehicle is involved in a collision or falls into water, etc., the breakage of the window can still be continued through the backup power supply 70, the successful triggering of the breakage of the window of the vehicle in any working environment is ensured, and since the backup power supply 70 is also located on the door 40, the electrical connection line between the backup power supply 70 and the driving member 32 is shortened, the circuit line can be shortened to prevent the electrical connection between the backup power supply 70 and the driving member 32 from failing, and the vehicle can be normally triggered when the breakage of the window is needed.
