Technical Field

[0001] This utility model relates to the field of automotive safety technology, and in particular to an automotive safety device that enables rapid external window breaking for rescue. Background Technology

[0002] In recent years, new energy vehicles have emerged and been widely used, and their door lock designs have also become more diverse, such as concealed, semi-concealed, and electronic locks. However, when new energy vehicles encounter emergencies (such as collisions, falling into water, or battery fires) that trap people inside, external rescuers are often unable to carry out rescues quickly due to the complexity of door lock types, vehicle power outages, or lack of suitable breaching tools.

[0003] Therefore, this safety device aims to overcome the limitations of existing technologies and provide a car safety device that allows for rapid window breaking and rescue in emergency situations, thus solving the problem that it is difficult for outsiders to quickly break windows to rescue passengers who have fallen into water, caught fire, or been knocked unconscious by an impact.

The information processing module includes an information control unit and several sensor modules distributed on the vehicle chassis. The information control unit is electrically connected to an electromagnetic switch and is used to process the information collected by the sensor modules.

[0006] This safety device includes a window-breaking circuit module and an information processing module, both installed on the vehicle body. The window-breaking circuit module comprises a power supply unit, an electronic window breaker, an electromagnetic switch, and a mechanical push-button switch. These components are connected in series via wires, with the mechanical push-button switch mounted on the door handle. The information processing module includes an information control unit and several sensor modules distributed on the vehicle chassis to collect vehicle status information. The information control unit is electrically connected to the vehicle's battery, which powers it to ensure it is energized. This information control unit is also electrically connected to the electromagnetic switch. It processes the collected vehicle status information. When the information control unit receives a danger signal, it activates the electromagnetic switch. Pressing the mechanical push-button switch then completes the circuit, triggering the electronic window breaker to quickly shatter the door glass, facilitating rescue of occupants. This safety device is simple, convenient, and effective.

[0007] Preferably, the power supply unit uses a battery module, which is electrically connected to the vehicle's alternator. This battery module, connected to the vehicle's alternator, allows the alternator to charge the battery module, ensuring sufficient power for the power supply unit. This, in turn, ensures the window-breaking circuit module remains powered in case of danger, resulting in good performance.

[0008] Preferably, the sensor module can be used to collect information on collisions, water immersion, or battery thermal runaway. This ensures comprehensive collection of vehicle hazard information, facilitating the information control unit to process the data and activate the electromagnetic switch, thereby activating the window-breaking circuit module and improving its effectiveness.

[0009] Preferably, the electronic window breaker includes a mounting bracket, a pointed piston rod, an ignition tube, and a metal housing.

[0011] Preferably, the inner bottom surface of the protective cover is provided with a clearance notch, and a plurality of evenly spaced support plates are arranged around the clearance notch. The clearance notch is aligned with the tip of the pointed piston rod. The clearance notch on the inner bottom surface of the protective cover facilitates the pointed piston rod to pierce the protective cover, resulting in better performance. Simultaneously, the support plates around the clearance notch correspond to the conical surface of the pointed piston rod. When the pointed piston rod is pushed outward, the support plates can contact the conical surface of the pointed piston rod, providing a reaction force to prevent excessive extension of the pointed piston rod and ensuring the good performance of the safety device.

[0012] Preferably, a guide ring is fitted inside the protective cover, and an installation ring is provided on the outer wall of the end of the guide ring. The installation ring is embedded in a slot, and the guide ring has a guide hole. The rod of the pointed piston rod is sleeved with the guide hole. Specifically, the guide ring fitted inside the protective cover, with an installation ring at its end that can be embedded in the slot, ensures stable and reliable installation of the guide ring. The guide hole in the middle of the guide ring sleeves with the rod end of the pointed piston rod. This structure guides the pointed piston rod, allowing it to accurately break the window, resulting in a highly effective safety device.

[0013] Preferably, the pointed piston rod has a piston head at its tail end, a sealing groove on its side wall, a sealing ring installed within the sealing groove, and a bushing fitted inside the metal housing. The side wall of the piston head is slidably connected to the bushing. Specifically, the pointed piston rod has a piston head at its tail end, a sealing groove on its side wall, and an annular sealing ring fitted inside the sealing groove. The bushing inside the metal housing allows the piston head to slide within it, and the bushing guides the piston head. The sealing ring also improves the sealing effect between the ignition tube and the piston head, ensuring the stable and rapid impact of the pointed piston rod against the door glass, thus guaranteeing the effectiveness of the safety device.

[0014] Preferably, the ignition tube is sleeved with the bushing, the side wall of the metal casing is provided with a diffusion hole, the tail of the ignition tube is connected to the bottom surface of the metal casing, and the ignition tube is electrically connected to the window-breaking circuit module.

[0029] The ignition tube 5 is sleeved with the bushing 43, the tail of the ignition tube 5 is connected to the bottom surface of the metal casing 6, and the ignition tube 5 is electrically connected to the window breaking circuit module 1.

[0030] The working principle of this utility model is as follows: Figure 1-3As shown, this safety device includes a window-breaking circuit module 1 and an information processing module 2, both installed on the vehicle body. The window-breaking circuit module 1 includes a power supply unit 10, an electronic window breaker 11, an electromagnetic switch 12, and a mechanical push-button switch 13. These components are connected in series via wires, and the mechanical push-button switch 13 is mounted on the door handle. The information processing module 2 includes an information control unit 20 and several sensor modules 21 distributed on the vehicle chassis to collect vehicle status information. The information control unit 20 is electrically connected to the vehicle's battery, which powers it to ensure it is always energized. The information control unit 20 is electrically connected to the electromagnetic switch 12. The information control unit 20 processes collected vehicle status information. When the information control unit 20 receives a danger signal, it can activate the electromagnetic switch 12. Then, by pressing the mechanical installation switch, the window-breaking circuit module 1 is connected, activating the electronic window breaker 11 to quickly shatter the vehicle door glass, facilitating rescue of occupants. This safety device is simple and convenient to operate, and its effectiveness is excellent.

[0031] The power supply unit 10 uses a battery module, which is connected to the vehicle's alternator. The alternator can charge the battery module, ensuring sufficient power for the power supply unit 10. This ensures that the window breaking circuit module 1 can be powered normally in case of danger, resulting in good performance.

[0032] Among them, the sensor module 21 is used to collect information on collisions, water immersion, or battery thermal runaway, ensuring that comprehensive information on vehicle hazards can be collected. This allows the main information control unit 20 to process the information and then connect the electromagnetic switch 12 to activate the window breaking circuit module 1, resulting in better performance.

[0033] The electronic window breaker 11 consists of a mounting bracket 3, a pointed piston rod 4, an ignition tube 5, and a metal housing 6. The mounting bracket 3 is fixedly installed on the door glass. An mounting cylinder 30 is installed on the mounting bracket 3, which is arranged perpendicular to the door glass. The metal housing 6 is connected to the mounting cylinder 30 by a sleeve. The pointed piston rod 4 and the ignition tube 5 are respectively installed in the mounting cylinder 30 and the metal housing 6. The pointed end of the pointed piston rod 4 faces the door glass, and the ignition tube 5 is located at the rear end of the pointed piston rod 4. When the ignition tube 5 is ignited, it can push the pointed piston rod 4 towards the door glass, breaking the door glass and facilitating subsequent rescue. This safety device is simple to operate and has good performance.

[0034] The mounting cylinder 30 has a clearance hole 31 on its bottom surface. A protective cover 32 is fitted inside the mounting cylinder 30. The protective cover 32 has a U-shaped barrel structure in cross-section. A slot 33 is provided on the inner side wall of the mounting cylinder 30. A flange 34 is provided at the port of the protective cover 32. The flange 34 can be inserted into the slot 33 to ensure the installation reliability of the protective cover 32. This structure can isolate the pointed piston rod 4 from the door glass, preventing the pointed piston rod 4 from damaging the door glass due to the vibration of the vehicle body, and ensuring good performance.

[0035] The protective cover 32 has a clearance notch 35 on its inner bottom surface, which allows the pointed piston rod 4 to easily pierce the protective cover 32, resulting in good performance. At the same time, several support plates 36 are arranged around the clearance notch 35. The support plates 36 correspond to the conical surface of the pointed piston rod 4. When the pointed piston rod 4 is pushed outward, the support plates 36 can contact the conical surface of the pointed piston rod 4. The support plates 36 can provide a reaction force to the pointed piston rod 4, preventing the pointed piston rod 4 from being pushed out excessively, thus ensuring the good performance of the safety device.

[0036] The protective cover 32 has a guide ring 37 inside, and an installation ring 38 is provided at the end of the guide ring 37. The installation ring 38 can be embedded in the slot 33 to ensure that the guide ring 37 is installed stably and reliably. The guide ring 37 has a guide hole 39 in the middle, which is sleeved with the rod end of the pointed piston rod 4. This structure can guide the pointed piston rod 4, which can accurately break the window, making the safety device effective.

[0037] The pointed piston rod 4 has a piston head 40 at its tail end. The side wall of the piston head 40 has a sealing groove 41, and an annular sealing ring 42 is fitted inside the sealing groove 41. At the same time, a bushing 43 is provided inside the metal shell 6. The piston head 40 can slide inside the bushing 43. The bushing 43 can guide the piston head 40. The sealing ring 42 can improve the sealing effect between the ignition tube 5 and the piston head 40, ensuring that the pointed piston rod 4 can stably and quickly pierce the door glass, thus ensuring the effectiveness of the safety device.

[0038] The ignition tube 5 is connected to the bushing 43. A diffuser hole 44 is provided on the outside of the metal shell 6. The tail of the ignition tube 5 is connected to the bottom surface of the metal shell 6. The ignition tube 5 is electrically connected to the window breaking circuit module 1. The ignition tube 5 can be activated by the electrical signal of the window breaking circuit module 1, which increases the gas pressure in the bushing 43, thereby pushing the pointed piston rod 4 to move and thus realizing the window breaking operation. At the same time, when the ignition pressure inside the window breaking generator exceeds the upper limit, the pressure will open the bushing 43, and the excessive pressure will be released from the diffuser hole 44 on the side, ensuring the integrity of the window breaking generator. The safety device has a good effect.

[0039] When the sensor array in this device detects an emergency such as a collision, flooding, or battery thermal runaway, real-time data is transmitted to the main control unit. The main control unit then activates the electromagnetic switch, establishing a circuit in the window-breaking circuit module and activating the external rescue device. At this point, the rescuer simply needs to press the mechanical button switch, prominently located on the door handle, to trigger the power supply unit to release a momentary current to the electronic window breaker, activating it and enabling the directional window breaker to break. When the electronic window breaker is activated, the ignition tube instantly deploys upon receiving the ignition current, generating a large amount of gas. The resulting pressure pushes the pointed piston rod forward, breaking the window.

[0040] Example 2: The sensor module can be used to detect abnormal vehicle conditions in different states. These abnormal vehicle conditions include: setting up a temperature sensor module at the car's battery to detect whether the battery spontaneously combusts; setting up a sensor module at the airbag to detect whether the airbag is activated and deployed, and whether the vehicle body has been involved in a collision; setting up a water immersion sensor to detect whether water has entered the vehicle body; and setting up a temperature sensor module inside the vehicle body to detect whether the internal circuitry or interior components are burning.

[0041] In Example 3, in addition to the mechanical button switch located on the exterior door handle, another mechanical button switch can be connected in parallel inside and located on the interior door handle. This allows for quick window breaking and self-rescue from the inside in case of an emergency.

[0042] Example 4: The main control unit of this information uses a C51 microcontroller to realize information monitoring and control, and the temperature sensor module uses a Kemin sensor to realize temperature monitoring.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
