Description

Technical Field

[0001] This invention relates to the field of automotive safety tools, and in particular to a dual-trigger window breaker. Background Technology

[0002] With the development of the automotive industry, the impact resistance of automotive safety glass has been continuously improved. However, serious escape difficulties remain in emergency situations (such as vehicle flooding, fire, or collision deformation). On the one hand, the high impact resistance of automotive safety glass makes it difficult for occupants to break the window by hand or with simple tools to escape. On the other hand, the concealed door handle design commonly used in modern cars may fail to pop out in a side collision due to damage to components such as sensors, retractors, or motors, preventing rescuers from opening the door and further complicating the rescue. While window breaker products are available on the market for escape by breaking windows, they generally suffer from the following drawbacks:

[0003] Pneumatic window breaker: This device uses an internal air pressure change to impact a striker, similar to a car airbag. The sudden pressure change causes the striker to shatter the glass. However, its core components (such as the generator) have a 15-year shelf life. This means that the device may fail due to the generator expiring during the vehicle's service life, rendering it ineffective in critical situations and severely impacting its reliability. Furthermore, the gas explosion caused by the pressure change generates a loud noise exceeding 110 dBA, far exceeding the 90 dBA threshold for human comfort and safety, potentially causing adverse hearing damage to trapped individuals and rescue personnel.

[0004] Manual pull-ring window breaker: It only supports single manual triggering. In the event of an accident, if the trapped person's movement is restricted (such as injury or entrapment), they may not be able to pull the pull ring effectively, resulting in failure to break the window.

[0005] The aforementioned problems collectively result in the low efficiency and unreliability of existing car window breakers in emergency situations, and may also bring additional safety hazards and inconveniences; therefore, there is an urgent need for a window breaker that is highly reliable, has flexible triggering methods, and is accurate in breaking windows. Summary of the Invention

[0006] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the objective of the present invention is to propose a dual-trigger window breaker, which features dual triggering modes, covers multiple scenarios, offers flexible triggering methods, is unaffected by the expiration date of the generating agent, has high reliability, and provides precise window breaking.

[0007] To achieve the above objectives, embodiments of the present invention provide a dual-trigger window breaker, comprising: an actuator, a striking pin, and a coil spring;

[0008] The actuator is provided with a mechanical triggering mechanism, an electrical triggering interface, a locking element, and a guide element; the mechanical triggering mechanism and the electrical triggering interface are respectively linked with the locking element so that the locking element can be driven to switch between a locked state and an unlocked state when the mechanical triggering mechanism is actuated or the electrical triggering interface receives an external electrical signal.

[0009] The firing pin is disposed on the coil spring, and the firing pin is guided and engaged with the guide member;

[0010] The coil spring has a connecting portion that connects to the striker. The connecting portion is locked by the locking member to allow the coil spring to store energy. When the coil spring releases energy, it drives the striker to strike the car window under the guidance of the guide member.

[0011] According to an embodiment of the present invention, a dual-trigger window breaker improves emergency reliability through dual-mode triggering of a mechanical triggering mechanism and an electrical triggering interface. The manual and electrical triggering methods complement each other, allowing for flexible triggering even when the movement of the driver or passenger is restricted and manual operation is not possible. The use of a coiled spring to store energy instead of a gas generator ensures that the effective service life of the product is not affected by the deterioration of the raw materials, and the structure is stable. The cooperation between the guide and the impact pin ensures a stable impact direction, avoids deviation that could lead to window breaking failure, and ensures precise impact for efficient window breaking.

[0012] In addition, the dual-trigger window breaker proposed in the above embodiments of the present invention may also have the following additional technical features:

[0013] Optionally, the mechanical triggering mechanism includes an unlocking plate for assembling the emergency pull ring. The unlocking plate is linked to the locking component. When the emergency pull ring is pulled, it drives the unlocking plate to switch the locking component from the locked state to the unlocked state. Thus, through the mechanical triggering mechanism of the unlocking plate and the emergency pull ring, the user can directly pull the pull ring to quickly release the locking component, suitable for intuitive operation in emergency scenarios. The mechanical linkage structure is simple, without complex electronic components, reducing the risk of accidental triggering or jamming.

[0014] Optionally, the electrical trigger interface is an external electrical interface used to receive external electrical signals to drive the locking element to switch from the locked state to the unlocked state.

[0015] Optionally, the locking element is rotatably mounted on the actuator, and the mechanical triggering mechanism and the electrical triggering interface are adapted to drive the locking element to rotate and switch between the locked state and the unlocked state.

[0016] Optionally, the locking element has a hook for engaging the connecting portion to lock the coil spring.

[0017] Optionally, the guide member is provided with a guide hole for guiding the impact direction of the firing pin, the firing pin passing through the guide hole and being guided and engaged with the guide hole.

[0018] Optionally, it also includes a cover connected to the actuator to collectively define a receiving cavity for receiving the firing pin and the coil spring, with the impact head of the firing pin extending out of the receiving cavity.

[0019] Furthermore, the coil spring is mounted on the actuator or inside the cover, the connecting part is the end of the coil spring, and the end of the striking pin away from its impact head is connected to the connecting part.

[0020] Furthermore, the guide member is a plate extending toward the cover, and the guide hole penetrates the thickness of the plate; the cover has a notch for inserting the plate at a position corresponding to the plate; after the plate is inserted into the notch, its edge seals against the edge of the notch to keep the receiving cavity closed.

[0032] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] The following is in conjunction with the appendix Figures 1-6 A detailed description of the dual-trigger window breaker according to an embodiment of the present invention.

[0034] The dual-trigger window breaker according to embodiments of the present invention aims to solve the problems of poor reliability (affected by shelf life), high noise, and inconvenience of operation in emergency situations of existing car window breakers.

[0035] like Figure 1 As shown, the dual-trigger window breaker according to an embodiment of the present invention includes an actuator 100, a striking pin 200, and a coil spring 300.

[0036] Specifically, the actuator 100 is provided with a mechanical triggering mechanism 110, an electrical triggering interface 120, a locking member 130, and a guide member 140. The mechanical triggering mechanism 110 and the electrical triggering interface 120 are respectively linked with the locking member 130 so that when the mechanical triggering mechanism 110 is actuated or the electrical triggering interface 120 receives an external electrical signal, the locking member 130 can be driven to switch between a locked state and an unlocked state. The striker 200 is disposed on the coil spring 300, and the striker 200 is guided and cooperated with the guide member 140. The coil spring 300 has a connecting part 310 connected to the striker 200. The connecting part 310 is locked by the locking member 130 so that the coil spring 300 stores energy. When the coil spring 300 releases energy, it drives the striker 200 to strike the car window under the guidance of the guide member 140.

[0037] In other words, the actuator 100 serves as the integrated carrier of the entire window breaker, internally accommodating and coordinating the operation of various components to ensure a compact structure and stable function; the impact pin 200 is a key component used to directly impact and shatter the car glass, and its impact head can concentrate energy to achieve efficient window breaking; the coil spring 300 serves as an energy storage and release unit, providing the instantaneous impact force required to drive the impact pin 200 when released, and its mechanical energy storage method avoids the shelf-life problem caused by chemical reactions; the locking element 130 is used to lock the energy storage state of the coil spring in the standby state to prevent its accidental release and ensure the safety of the window breaker; the mechanical triggering mechanism 110 is adapted to allow manual switching of the state of the locking element 130 to trigger the window breaker; the electric triggering interface 120 serves as the interface for the electric drive triggering mechanism, receiving external electrical signals (such as signals from the vehicle safety system), and switching the state of the locking element 130 through electric drive to trigger the window breaker.

[0038] Therefore, according to an embodiment of the present invention, a dual-trigger window breaker improves emergency reliability through dual-mode triggering via a mechanical triggering mechanism 110 and an electrical triggering interface 120. The manual and electrical triggering methods complement each other; even when the driver or passenger is unable to operate manually due to limited mobility, triggering can still be achieved via an electrical signal, providing flexibility. The use of a coil spring 300 for energy storage replaces the gas generator, ensuring the product's effective lifespan is unaffected by raw material deterioration and maintaining structural stability. The cooperation between the guide 140 and the impact pin 200 ensures stable impact direction, preventing deviation and resulting window breaking failure, and precise impact guarantees window breaking efficiency. In other words, this solution, by combining the mechanical energy storage of the coil spring and the dual-trigger mechanism, overcomes the shortcomings of existing technologies that rely on chemical reactions (shelf life issues) and single triggering methods (operational limitations), providing a safer, more reliable, and more flexible automotive window breaking solution.

[0039] The working principle of this window breaker is as follows: When the window breaker is in normal standby mode, such as Figure 2 As shown, the coil spring 300 is pre-deformed and stores energy. At this time, the locking member 130 securely locks the coil spring 300, preventing it from releasing its elastic potential energy and ensuring the window breaker is in a safe locked state. Simultaneously, the coil spring 300, through its connecting part 310, holds the striking pin 200 in its initial position, preventing it from protruding and avoiding accidental activation. The guide member 140 pre-sets a precise movement path for the striking pin 200, ensuring it impacts in the correct direction after triggering. When an emergency occurs and window breaking is required, it can be triggered in two independent and complementary ways: one is manual triggering, where the user actuates the mechanical trigger mechanism 110, thereby disengaging the locking member 130 from the coil spring 300, such as... Figure 3As shown. Secondly, it is electrically driven, receiving an electrical signal from the vehicle safety system via the electrical trigger interface 120. This electrical signal drives the electric drive mechanism (e.g., a small motor or electromagnet) inside the actuator 100, causing it to actuate and drive the locking member 130 to unlock and release the coil spring 300, as shown. Figure 3 As shown. Whether manually or electrically triggered, once the locking element 130 unlocks, the energy-stored coil spring 300 immediately releases its stored powerful elastic potential energy. The elastic force of the coil spring 300 instantly acts on the impact pin 200, driving it forward at extremely high speed under the guidance of the guide element 140. Under the high-speed impact, the impact head of the impact pin 200 concentrates energy to shatter the car window, thus quickly providing an escape route for the occupants. The entire process relies purely on mechanical energy conversion, avoiding the shelf life and noise problems caused by chemical reactions, ensuring the immediacy and effectiveness of breaking the window.

[0040] According to one or more embodiments of the present invention, the mechanical triggering mechanism 110 includes an unlocking plate 111 for mounting an emergency pull ring. The unlocking plate 111 is linked with the locking member 130. When the emergency pull ring is pulled, the unlocking plate 111 drives the locking member 130 to switch from the locked state to the unlocked state. Thus, through the mechanical triggering mechanism of the unlocking plate 111 and the emergency pull ring, the user can directly pull the pull ring to quickly release the locking member 130, suitable for intuitive operation in emergency scenarios. The mechanical linkage structure is simple, without complex electronic components, reducing the risk of accidental triggering or jamming. More specifically, the unlocking plate 111 is a long strip plate with a hanging hole structure at one end adapted to the emergency pull ring.

[0041] According to one or more embodiments of the present invention, the electrical trigger interface 120 is an external electrical interface used to receive external electrical signals to drive the locking member 130 to switch from the locked state to the unlocked state. This allows compatibility with vehicle safety systems; for example, in the event of an emergency such as a collision, rollover, or submersion in water, an electrical signal is sent to the window breaker via the external electrical interface. This signal drives the electric drive mechanism 150 inside the actuator 100, causing it to actuate and unlock the locking member 130, releasing the coil spring 300. Alternatively, it can be triggered by an electrical signal from an external device, automatically activating after an accident, or triggered remotely via command when the user cannot operate it manually, expanding application scenarios and improving the product's intelligent adaptability.

[0042] According to one or more embodiments of the present invention, the locking member 130 is rotatably disposed on the actuator 100, and the mechanical triggering mechanism 110 and the electrical triggering interface 120 are adapted to drive the locking member 130 to rotate, thereby switching between the locked state and the unlocked state. This rotatable arrangement of the locking member 130 enables smooth state switching; the rotating structure exhibits low motion resistance, resulting in faster locking / unlocking response and reduced triggering delay; furthermore, both the mechanical and electrical triggering mechanisms can drive the locking member 130 to rotate, ensuring stable operation of the dual-mode triggering and improving the overall reliability of the mechanism.

[0043] More specifically, such as Figure 5 and Figure 6 As shown, the locking element 130 is rotatably mounted on the actuator 100 via the pivot 160.

[0044] The unlocking plate 111 is directly sleeved on the end of the rotating shaft 160 that is away from the locking member 130 and extends out of the actuator 100. The unlocking plate 111 is rotatably connected to the actuator 100 through the rotating shaft 160. When receiving manual pulling force, it can drive the rotating shaft 160 to rotate and drive the locking member 130 to switch from the locked state to the unlocked state, thereby realizing mechanical triggering.

[0045] The electric drive mechanism 150 can employ a motor and gear set structure. The gear set structure is connected to the rotating shaft 160, and the motor is connected to the gear set structure. The electric trigger interface 120 is electrically connected to the motor. When the electric trigger interface 120 receives an external electrical signal, the motor operates to drive the rotation of the gear set structure, which in turn drives the rotating shaft 160 to rotate, thereby driving the locking element 130 to switch from the locked state to the unlocked state, achieving electric triggering. Compared to a simple electromagnet, this electric drive mechanism 150 can provide a more precise, stable, and powerful driving force to unlock the locking element 130. The combination of the motor and gear set can achieve speed reduction and torque increase, ensuring that the locking force of the locking element 130 can be reliably overcome under various working conditions, thus guaranteeing the smooth release of the coil spring 300. This implementation method improves the reliability and control accuracy of electric drive triggering, avoids triggering failure due to insufficient or unstable driving force, and further enhances the overall reliability of the window breaker in emergency situations.

[0046] According to one or more embodiments of the present invention, the locking member 130 has a hook 131 for hooking the connecting part 310 to lock the coil spring 300. The hook 131 can tightly hook the connecting part 310 of the coil spring 300 to ensure stable energy storage of the coil spring 300 and avoid unexpected release; when released, the connecting part 310 can be instantly disengaged to ensure that the energy of the coil spring 300 is fully released and drives the firing pin 200 to generate sufficient impact force to break the window.

[0047] In other words, in normal standby mode, the coil spring 300 is pre-deformed and stores energy. At this time, the hook 131 firmly hooks onto the connecting part 310 of the coil spring 300, preventing it from releasing its elastic potential energy and ensuring that the window breaker is in a safe locked state. When the user pulls the emergency pull ring that matches the unlocking plate 111, the pulling force acts on the unlocking plate 111, thereby causing the locking member 130 to rotate and disengage the hook 131 from locking the coil spring 300. Alternatively, when the electric trigger interface 120 receives an electrical signal from the vehicle safety system, the electrical signal drives the electric drive mechanism inside the actuator 100, causing it to move and drive the locking member 130 to rotate, thereby disengaging the hook 131 from locking the coil spring 300.

[0048] According to one or more embodiments of the present invention, the guide member 140 is provided with a guide hole 141 for guiding the impact direction of the striker 200. The striker 200 passes through the guide hole 141 and is guided and engaged with the guide hole 141. In this way, the guide hole 141 restricts the movement trajectory of the striker 200, avoiding directional deviation during impact and reducing the window-breaking force; the engagement of the striker 200 through the guide hole 141 improves the stability of movement, ensures that the impact force is concentrated on the window, and improves the window-breaking efficiency.

[0049] According to one or more embodiments of the present invention, the window breaker further includes a cover 400 connected to the actuator 100 to jointly define a receiving cavity for accommodating the striker 200 and the coil spring 300, with the impact head of the striker 200 extending out of the receiving cavity. Thus, the closed receiving cavity isolates the external environment, protecting the coil spring 300, locking member 130, etc., from corrosion and extending the product lifespan; the design of the impact head extending out of the receiving cavity ensures direct contact with the vehicle window upon impact, avoiding interference from the cover. In other words, the cover 400 is an external structural component used to encapsulate and protect these internal functional components. Together with the actuator 100, it constitutes the overall structure of the window breaker, specifically protecting the internal structure; effectively preventing damage to internal mechanical components from dust, moisture, external impacts, or accidental contact, thereby ensuring the window breaker maintains its reliability and functional stability throughout the vehicle's entire service life, even in harsh automotive environments. This is crucial for ensuring a high success rate in emergency window breaking situations.

[0050] According to one or more embodiments of the present invention, the coil spring 300 is mounted on the actuator 100 or inside the cover 400, the connecting portion 310 is the end of the coil spring 300, and the end of the striking pin 200 away from its impact head is connected to the connecting portion 310. The coil spring 300 can be mounted on the actuator 100 or the cover 400 to adapt to different product structure requirements; the end of the coil spring 300 is connected to the rear end of the striking pin 200, which can maximize the conversion of the energy of the coil spring 300 into the impact force of the striking pin and improve the window breaking effect.

[0051] More specifically, a helical coil spring 300 is used as the energy storage unit, which can store a large amount of elastic potential energy in a relatively compact space and provide a powerful and instantaneous impact force upon release. Due to its structural characteristics, the helical coil spring has good compression stroke and mechanical properties, which can ensure that the impact pin 200 obtains a sufficiently high speed and energy in a short time, thereby efficiently and reliably shattering the car glass.

[0052] Furthermore, the striking pin 200 is mounted on the coil spring 300. The flexibility of the coil spring 300, which can be mounted on the cover 400 or assembled on the actuator 100, provides greater freedom for the structural design and vehicle integration of the window breaker. This design flexibility allows the window breaker to better adapt to the needs of different vehicle models and different installation spaces, optimize component layout, simplify the production and assembly process, and help achieve a more compact or modular product design, thereby reducing manufacturing costs and improving product versatility.

[0053] Among them, such as Figure 2 or Figure 3 As shown, when the coil spring 300 is mounted on the actuator 100, a mesh rib extends from the outer wall of the actuator 100 and a mounting shaft is set at the center of the mesh rib. The mounting shaft is connected to the inner end of the coil spring 300 through a bayonet. The mesh rib contacts the side of the coil spring 300 facing the actuator 100, which makes the coil spring 300 release and store energy more smoothly.

[0054] According to one or more embodiments of the present invention, the guide member 140 is a plate extending toward the cover 400, and the guide hole 141 penetrates the thickness of the plate; the cover 400 is provided with a notch for inserting the plate at a position corresponding to the plate; after the plate is inserted into the notch, its edge seals against the edge of the notch to keep the receiving cavity closed. That is, the guide member 140 and the notch of the cover 400 cooperate to make the window breaker compact in overall structure while having the guiding function of the striker 200, and can protect internal components such as the coil spring 300 and the rotating shaft.
