[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0038] See also Figure 1 , which shows an example of the window breaking device provided by the present invention.

[0039] As can be seen from the figure, the window breaking device of this example is used to cooperate with the window of a car, and mainly includes a window breaking unit 100 and a signal triggering unit 200.

[0040] The window breaking unit 100 mainly includes a driving mechanism 101 and a window breaking mechanism 102. The driving mechanism 101 is configured to provide driving power to the window breaking mechanism 102 and control the window breaking mechanism 102 to reciprocate between an initial state and a window breaking state, so that the window breaking unit 100 can perform multiple window breaking actions to ensure the effectiveness of window breaking.

[0041] Furthermore, the signal trigger unit 200 is connected to the driving mechanism 101 in the window breaking unit 100, and is configured to monitor impact, water level, smoke status and button signals, generate a trigger signal, and control the working state of the driving mechanism 101 according to the trigger signal, so that the signal trigger unit 200 can self-start or manually start the window breaking unit 100 in a variety of emergency situations, so as to increase the use scenarios of the emergency escape window breaking unit and improve the window breaking efficiency.

[0042] Among them, the signal trigger unit 200 includes an environmental signal component 210 and a vehicle body signal component 220. The environmental signal component 210 includes a collision sensor, a water level sensor, a smoke sensor and a camera arranged in the vehicle or indoors, so that the signal trigger unit 200 can monitor the collision, water level and smoke status through the environmental signal component 210 when the vehicle or indoors encounters an emergency situation such as collision, falling into water, fire, etc. When the monitoring value reaches the threshold preset by the signal trigger unit 200, an environmental trigger signal is generated to enable the signal trigger unit 200 to control the driving mechanism 101 in the window breaking unit 100 to work, so that the window breaking unit 100 can self-start the window breaking action.

[0043] Furthermore, the vehicle body signal component 220 in the signal trigger unit 200 includes an SOS button and / or a vehicle body controller arranged in the vehicle or indoors, so that when an emergency occurs, the user can press the SOS button and / or a vehicle body controller to enable the vehicle body signal component 220 to obtain a button signal and generate a vehicle body trigger signal, thereby enabling the signal trigger unit 200 to control the driving mechanism 101 in the window breaking unit 100 to work and manually start the window breaking unit 100.

[0044] The signal trigger unit 200 thus constructed can cooperate with the environmental signal component 210 and the vehicle body signal component 220 to realize the self-starting and manual starting of the window breaking unit 100 in various emergency situations, while improving the window breaking efficiency.

[0045] In coordination therewith, the window breaking unit 100 cooperates with the signal triggering unit 200, so that the window breaking unit 100 starts to work under the environmental triggering signal and the vehicle body triggering signal.

[0046] Among them, combined Figure 2 Two independent chambers are formed on the base 2 of the window breaking unit 100, and the two chambers are sealed by the controller cover 1 and the window breaking mechanism cover 2 respectively, so that the driving mechanism 101 is placed in a chamber separated from the window breaking mechanism 102, avoiding the noise and grease generated by the movement of the window breaking mechanism 102 to affect the driving mechanism 101.

[0047] In this example, the driving mechanism 101 is composed of an integrated driving mechanism, including a capacitor 4 and a capacitor ECU5. The capacitor 4 is charged by a battery in the vehicle or indoors, and the storage capacity of the capacitor 4 is ensured to be sufficient to drive the window breaking mechanism 102 to change back and forth between the initial state and the window breaking state, so that the window breaking unit 100 can perform multiple window breaking actions to ensure the effectiveness of window breaking.

[0048] Here, the storage capacity of the capacitor 4 is preferably adapted to the electrical energy required by the window breaking mechanism to break the window three times, so as to ensure that the window breaking mechanism can achieve at least three window breaking actions and ensure effective window breaking.

[0049] Furthermore, combined with Figure 3 The window breaking mechanism 102 includes a motor assembly 110, a gear linkage assembly 120 and a release assembly 130. The motor assembly 110 is connected to the release assembly 130 through the gear linkage assembly 120, and can also drive the gear linkage assembly 120 and the release assembly 130 to move synchronously, so that the release assembly 130 can quickly break the window and improve the window breaking efficiency.

[0050] Combination Figure 1 and Figure 3 The motor assembly 110 includes a motor 17 , which is fixed on the base 2 , and a motor cover 9 is provided on the motor 17 to protect the motor 17 from external influences, thereby extending the service life of the motor 17 .

[0051] Here, the specific structure of the motor 17 is not limited. For example, the motor 17 can be composed of an existing brushless DC motor, a brushed DC motor or a ripple motor.

[0052] Furthermore, the motor 17 is connected to the capacitor 4 through the capacitor ECU5 in the driving mechanism 101, so that the capacitor ECU5 can control the capacitor 4 to discharge the motor 17, so that the motor 17 can rotate, driving the gear linkage assembly 120 and the release assembly 130 to move synchronously. The capacitor ECU5 can also control the reciprocating rotation of the motor 17 to drive the gear linkage assembly 120 and the release assembly 130 to reciprocate synchronously, thereby allowing the window breaking mechanism to reciprocate between the initial state and the broken window state.

[0053] In order to connect the motor 17 with the gear linkage assembly 120 and the release assembly 130, the motor assembly 110 also includes a worm 13, one end of the worm 13 is arranged on the output shaft of the motor 17, and the other end is fixed to the base 2 through a worm shaft pressure block 12 to prevent the worm 13 from swinging during rotation. The worm 13 can rotate synchronously with the motor 17.

[0054] In coordination therewith, the gear linkage assembly 120 comprises a bevel gear 8 for cooperating with the motor assembly 110, and the bevel gear 8 is provided with bevel teeth adapted to the worm 13, so that when the bevel gear 8 is arranged on the worm 13, the bevel gear 8 meshes with the worm 13, and the worm 13 can drive the bevel gear 8 to rotate synchronously.

[0055] Furthermore, the gear linkage assembly 120 also includes a spur gear 7 for cooperating with the release assembly 130. The spur gear 7 is connected to the helical gear 8 through a shaft 15, and a bearing 14 is provided at the end of the shaft 15. A bearing pressure block 6 is provided on the bearing 14, so that the bearing pressure block 6 cooperates with the bearing 14 to fix the displacement of the shaft 15, so that when the worm 13 drives the helical gear 8 to rotate synchronously, the helical gear 8 drives the spur gear 7 to rotate synchronously through the shaft 15.

[0056] Furthermore, combined with Figure 4 and Figure 5 The release assembly 130 includes a linkage outer shell 10 for cooperating with the gear linkage assembly 120. A rack 11 adapted to the spur gear 7 is provided on the outer wall of the linkage outer shell 10, so that the rack 11 is meshed with the spur gear 7. The rotation of the spur gear 7 can drive the linkage outer shell 10 to move axially through the rack 11.

[0057] Therefore, the gear linkage assembly 120 can serve as a connecting piece between the motor assembly 110 and the release assembly 130, so that the motor assembly 110 drives the gear linkage assembly 120 to move, and synchronously drives the release assembly 130 to move.

[0058] Combination Figure 6 and Figure 7 In order to enable the release component 130 to break the window under the drive of the motor component 110 and the gear linkage component 120, a cavity for accommodating the mounting seat 18 is formed in the linkage outer shell 10 of the release component 130. The mounting seat 18 is preferably composed of two semicircular shells to facilitate assembly, and a cavity is formed in the mounting seat 18.

[0059] In coordination with the mounting seat 18, a fixing bracket 16 is further provided at the bottom of the linkage outer shell 10, on which a fixing column 161 is protruding, and a cavity is formed inside the fixing column 161, so that the mounting seat 18 is sleeved on the fixing column 161, and a placement cavity 27 is formed between the mounting seat 18 and the fixing column 161. The axial movement of the linkage outer shell 10 can drive the mounting seat 18 to move toward the fixing column 161, thereby compressing the placement cavity 27.

[0060] Furthermore, a force storage spring 19, a window breaking spring 20 and a ejector pin assembly are arranged in the placement cavity 27. One end of the force storage spring 19 is connected to the inner top surface of the mounting seat 18, and the other end is connected to the top surface of the fixing column 161, so that when the mounting seat 18 moves toward the fixing column 161, pressure is applied to the force storage spring 19 to compress the force storage spring 19.

[0061] In coordination therewith, the window-breaking spring 20 is inserted into the force-storing spring 19 and sleeved on the ejector pin assembly, so that the window-breaking spring 20 and the force-storing spring 19 cooperate to store force on the ejector pin assembly and release the ejector pin assembly under the action of their own elastic force.

[0062] Specifically, combined Figure 8 The ejector pin assembly includes an ejector rod 22, a needle head 23 arranged at the end of the ejector rod 22, and a stopper 21 arranged in the middle area of ​​the ejector rod 22. The ejector rod 22 is inserted into the window breaking spring 20, so that the window breaking spring 20 is built into the force storage spring 19, and one end is connected to the inner top surface of the mounting seat 18, and the other end is connected to the stopper 21.

[0063] In order to enable the window breaking spring 20 and the force storage spring 19 to store and release force on the ejector assembly in the placement cavity, the circumferential surface of the block 21 is configured as an inclined surface, and a step 24 for abutting and cooperating with the block 21 is provided on the circumferential surface of the fixing column 161. The inner wall of the mounting seat 18 extends outward to form a release boss 25 that is compatible with the circumferential surface of the block 21, so that a force storage cavity 28 distributed on the outside of the placement cavity 27 is formed between the step 24 on the fixing column 161 and the release boss 25 of the mounting seat 18, so that the ejector assembly cooperates with the window breaking spring 20 and the force storage spring 19 to store force in the force storage cavity 28, and moves to the placement cavity 27 to release the elastic force, so that the needle 21 applies pressure to the vehicle window to break the window.

[0064] Specifically, in the initial state, the window breaking spring 20 and the ejector pin assembly are integrally arranged in the placement cavity 27 at an angle. At the same time, the end of the ejector pin 22 is connected to the inner top surface of the mounting seat 18, and the stopper 21 and the needle head 23 are arranged in the force storage cavity 28 along with the ejector pin 22 at an angle, so that the window breaking spring 20 is arranged in the force storage cavity 28 at an angle, and the stopper 21 is in abutment with the step 24 on the fixing column 161, and there is a gap between the release boss 25 on the mounting seat 18 and the step 24, such as Figure 7 shown.

[0065] Further, when the capacitor ECU 5 controls the motor 17 to rotate forward, so that the motor 17 drives the mounting seat 18 to move toward the fixed column 161 through the gear linkage assembly 120, pressure is applied to the force storage spring 19 and the window breaking spring 20, and the force storage spring 19 and the window breaking spring 20 are compressed, so that the force storage spring 19 and the window breaking spring 20 store elastic force. When the mounting seat 18 continues to move toward the fixed column 161, the release boss 25 will abut against the circumferential surface of the block 21 on the step 24. At this time, as the mounting seat 18 continues to move toward the fixed column 161, the release boss 25 will apply pressure to the circumferential surface of the block 21 in order to be able to continue to move toward the fixed column 161, so that the block 21 falls off from the step 24 under the action of pressure and falls to the middle area of ​​the placement cavity 27, as shown in FIG. Figure 5 shown.

[0066] At the same time, the window breaking spring 20 falls off from the step 24 together with the block 21 to the middle area of ​​the cavity 27 and releases the elastic force, so that the push rod 22 moves quickly toward the bottom surface of the fixed column 161 under the action of the elastic force, driving the needle 23 to be quickly released from the window breaking hole 26 on the bottom surface of the fixed column 161, applying pressure to the vehicle window, thereby breaking the vehicle window and changing the window breaking unit 100 from the initial state to the broken window state.

[0067] Thus, one window breaking action of the window breaking unit 100 is completed. In order to enable the window breaking unit 100 to perform multiple window breaking actions, the capacitor ECU 5 is configured to control the reciprocating rotation of the motor 17, so that the motor 17 drives the mounting seat 18 to reciprocate between facing and back to the fixed column 161 through the gear linkage assembly 120, thereby driving the window breaking unit 100 to reset from the broken window state to the initial state.

[0068] As an example, when the capacitor ECU 5 controls the motor 17 to rotate in the opposite direction, so that the motor 17 drives the mounting seat 18 to move back toward the fixed column 161 through the gear linkage assembly 120, it will synchronously drive the force storage spring 19, the window breaking spring 20 and the ejector assembly to move back toward the fixed column 161, and the force storage spring 19 will release the elastic force. At the same time, since the ejector rod 22 and the window breaking spring 20 are inclined, when moving back toward the fixed column 161, the ejector rod 22 and the window breaking spring 20 will move along the initial inclined path, so that the ejector rod 22 drives the block 21 to be re-placed on the step 24 on the fixed column 161, abutting and cooperating with the step 24, and driving the needle 23 to withdraw from the window breaking hole 26, so that the window breaking unit 100 is reset from the window breaking state to the initial state, so that the next window breaking action can be performed.

[0069] Furthermore, the capacitor ECU 5 controls the motor 17 to rotate in the forward direction again, which will drive the window breaking unit 100 to change from the initial state to the window breaking state again, so that the window breaking unit 100 can perform multiple window breaking actions to ensure effective window breaking.

[0070] In some embodiments, the driving mechanism 101 can also be composed of a split driving mechanism, including a roller and a pull wire wound on the roller, the roller is arranged on the gearbox of the motor 17, the pull wire is connected to the linked outer shell 10, and is configured so that when the motor 17 rotates forward, the motor 17 drives the roller to rotate forward, and can synchronously shorten the pull wire and roll it on the roller, so that the pull wire drives the linked outer shell 10 and the mounting seat 18 to move synchronously facing the fixed column 161, so that the window breaking unit 100 changes from the initial state to the broken window state, thereby achieving window breaking.

[0071] Furthermore, when the motor 17 rotates in the reverse direction, the motor 17 drives the roller to rotate in the reverse direction, which can synchronously release the pull wire from the roller and stretch it. At the same time, the pull wire returns to its initial position under the elastic force of the force storage spring 19, driving the linkage outer shell 10 and the mounting seat 18 to move synchronously back to the fixed column 161, thereby driving the window breaking unit 100 to reset from the broken window state to the initial state.

[0072] Thus, the window breaking device provided by the present invention is formed.

[0073] The present invention also provides a window breaking method, which uses a window breaking device formed by the above scheme, and the window breaking method comprises:

[0074] Combination Fig. 9 Before breaking the window, the car battery charges the capacitor 4, so that the capacitor ECU 5 controls the capacitor 4 to discharge the motor 17 and controls the motor 17 to rotate in the opposite direction, so that the motor 17 drives the mounting seat 18 to move synchronously back to the fixed column 161 through the worm 13 and the gear linkage assembly 120. When the motor 17 rotates in the opposite direction to the stop position and is blocked, the window breaking unit 100 is adjusted to the initial state and is ready to break the window.

[0075] Furthermore, when the environmental signal component 210 and the vehicle body signal component 220 in the signal trigger unit 200 obtain the environmental trigger and vehicle body trigger signals, the signal trigger unit 200 will control the capacitor ECU 5 to discharge the motor 17, and control the motor 17 to rotate forward, so that the motor 17 drives the mounting seat 18 to move synchronously toward the fixed column 161 through the gear linkage component 120. When the motor 17 rotates forward to the stop position and a stall occurs, the window breaking unit 100 changes from the initial state to the window breaking state, and performs a window breaking action.

[0076] At this time, the capacitor ECU 5 controls the motor 17 to rotate in the reverse direction. When the motor 17 rotates in the reverse direction to a stop position and is blocked, the window breaking unit 100 is reset from the window breaking state to the initial state, and is ready to break the window.

[0077] Next, the capacitor ECU 5 controls the motor 17 to rotate forward again. When the motor 17 rotates forward to the stop position and is blocked, the window breaking unit 100 changes from the initial state to the window breaking state again, and performs a secondary window breaking action.

[0078] By analogy, the capacitor ECU 5 controls the motor 17 to rotate back and forth, so that the window breaking unit 100 can break windows multiple times. Among them, the storage capacity of the capacitor 4 is preferably adapted to the electric energy required for the window breaking unit 100 to break windows three times, so as to ensure that the window breaking unit 100 can achieve at least three window breaking actions and effectively break the window.

[0079] The present invention also provides a vehicle, comprising a frame and a window arranged on the frame, wherein at least one corner of the window is provided with a window breaking device constituted by the above scheme, so that the window breaking device can act on the corner of the window and can quickly and effectively break the window.

[0080] Furthermore, the driving mechanism 101 can also be integrated into a driving control unit of the vehicle or a controller at other locations of the vehicle body to reduce the impact of the operation of the window breaking mechanism 102 on the driving mechanism 101 .

[0081] The window breaking device can also be used in indoor windows, so that people inside the room can quickly escape by breaking the windows through the window breaking device.

[0082] The following examples illustrate the working process of the present invention in a specific application. It should be noted that the following content is only a specific application example of the present solution and does not constitute a limitation to the present solution.

[0083] Combination Fig. 9 First, the capacitor 4 is charged by the car battery so that the storage capacity of the capacitor 4 is at least compatible with the electrical energy required by the window breaking unit 100 to break the window three times.

[0084] Next, the window breaking unit 100 is adjusted to the initial state, and the capacitor ECU 5 controls the capacitor 4 to discharge the motor 17, and controls the motor 17 to rotate in the opposite direction, so that the motor 17 drives the mounting seat 18 to move synchronously away from the fixed column 161 through the worm 13 and the gear linkage assembly 120. When the motor 17 rotates in the opposite direction to the stop position and is blocked, the window breaking unit 100 is adjusted to the initial state and is ready to break the window.

[0085] The environmental signal component 210 of the signal trigger unit 200 monitors the collision, water level and smoke status of the car in real time. When the monitoring value reaches the threshold preset by the signal trigger unit 200, the environmental signal component 210 generates an environmental trigger signal, so that the signal trigger unit 200 controls the capacitor ECU 5 to work, so that the window breaking unit 500 automatically starts the window breaking action.

[0086] Furthermore, when the person in the vehicle presses the SOS button, the vehicle body signal component 220 of the signal trigger unit 200 obtains the vehicle body trigger signal, so that the signal trigger unit 200 controls the capacitor ECU 5 to work, so as to manually start the window breaking unit 500.

[0087] Next, the capacitor ECU 5 controls the capacitor 4 to discharge the motor 17 according to the environmental trigger signal and the vehicle body trigger signal obtained by the signal trigger unit 200, and controls the motor 17 to rotate forward, so that the motor 17 drives the worm to rotate synchronously, so as to drive the helical gear 8 and the spur gear 7 to rotate synchronously in the opposite direction, so that the spur gear 7 drives the linkage outer shell 10 to move synchronously toward the fixed column 161 through the rack 11, so as to drive the mounting seat 18 to move synchronously toward the fixed column 161.

[0088] At this time, the mounting seat 18 applies pressure to the force storage spring 19 and the window breaking spring 20, compressing the force storage spring 19 and the window breaking spring 20, so that the force storage spring 19 and the window breaking spring 20 store elastic force, and the mounting seat 18 continues to move toward the fixed column 161, so that the release boss 25 abuts against the circumference of the block 21 on the step 24, and applies pressure to the circumference of the block 21, so that the block 21 falls off from the step 24 under the action of pressure, and falls from the force storage cavity 28 to the middle area of ​​the placement cavity 27.

[0089] At the same time, the window-breaking spring 20 falls off from the step 24 together with the block 21 to the middle area of ​​the cavity 27 and releases the elastic force, so that the push rod 22 moves quickly toward the bottom surface of the fixed column 161 under the action of the elastic force, driving the needle 23 to be quickly released from the window-breaking hole 26 on the bottom surface of the fixed column 161, exerting pressure on the car window, thereby breaking the car window.

[0090] At the same time, the motor 17 rotates forward to the stop position and is blocked, and the window breaking unit 100 changes from the initial state to the window breaking state, performing a window breaking action.

[0091] Next, the capacitor ECU 5 controls the motor 17 to rotate in the opposite direction, so that the motor 17 drives the worm to rotate synchronously, thereby driving the helical gear 8 and the spur gear 7 to rotate forward synchronously, so that the spur gear 7 drives the linkage outer shell 10 to move synchronously back to the fixed column 161 through the rack 11, thereby driving the mounting seat 18 to move synchronously back to the fixed column 161.

[0092] At this time, the mounting seat 18 synchronously drives the force storage spring 19, the window breaking spring 20 and the ejector pin assembly to move back toward the fixed column 161, the force storage spring 19 releases its elastic force, the ejector pin 22 and the window breaking spring 20 move along the initial inclined path, so that the ejector pin 22 drives the block 21 to be re-positioned on the step 24 on the fixed column 161, abuts against the step 24, and drives the needle 23 to withdraw from the window breaking hole 26.

[0093] At the same time, the motor 17 rotates in the reverse direction and stops, causing a stall. The window breaking unit 100 changes from the window breaking state to the initial state, preparing for a secondary window breaking action.

[0094] Next, the capacitor ECU 5 controls the motor 17 to rotate in the forward direction, so that the motor 17 drives the window breaking unit 100 to change from the initial state to the window breaking state again, and performs a secondary window breaking action.

[0095] By analogy, the capacitor ECU 5 can control the window breaking unit 100 to perform at least three window breaking actions through the motor 17 to effectively break the window.

[0096] The window breaking unit, window breaking method and vehicle provided by the present invention adopt the cooperation of the window breaking unit 100 and the signal triggering unit 200, so that the signal triggering unit 200 manually starts or automatically starts the window breaking unit 100 to break the window in various emergency situations, thereby improving the window breaking efficiency, and controls the window breaking unit 100 to change back and forth between the initial state and the broken window state through the capacitor ECU 5, thereby improving the window breaking efficiency.
