Description

Technical Field

[0001] This utility model relates to a window breaker, specifically an electronically controlled window breaker for use in vehicle emergencies. Background Technology

[0002] With the increase in car ownership, car accidents are also increasing. How to better save the lives of passengers and reduce injuries in traffic accidents is an important issue in the field of automotive safety. Besides traffic accidents, various other unexpected events can cause injury, such as vehicle fires, vandalism, falling into water, and malfunctions causing doors and windows to lock. In the event of an accident or incident where passengers cannot quickly escape through the doors, it becomes necessary to escape through broken windows.

[0003] Trapped individuals often attempt to break car windows using sharp objects inside the vehicle, as most items inside are inconvenient for smashing windows. While some cars are equipped with safety hammers, their fixed locations are not readily known, making them prone to loss. Using them requires considerable strength and skill, and untrained occupants, in moments of injury or panic, or when the vehicle is overturned or overturned, are often unable to effectively break tempered glass, thus delaying escape.

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Example 1: Please refer to Figures 1-2 An electrically controlled window breaker includes a bracket 1, a cover 2, and a magnetic impact rod 3. The bracket 1 includes a base plate 11 fixed to the vehicle window and a top plate 12 arranged parallel to the base plate. A hollow tubular slide 13 is provided through the middle of the base plate 11 and the top plate 12. An electromagnetic coil 4 is wound around the outer periphery of the tubular slide 13. The electromagnetic coil 4 is connected to an external power source through a wire with a switch. The upper end face of the tubular slide 13 is open, and the lower end face has a base plate hole 112 in the middle and is supported by an elastic structure 5, such as a spring. The upper edge of the tubular slide 13 is provided with a guide structure 6 that is integrated with the tubular slide. In some preferred embodiments, the guide structure 6 is a plurality of arc-shaped sheet structures, which are evenly arranged on the upper edge of the tubular slide 13. The inner side of the arc-shaped sheet structure is provided with a protruding block slide 62. Correspondingly, a groove is provided on the outer side of the magnetic impact rod 3. The groove can be embedded in the block slide 62. When the magnetic impact rod 3 moves, the block slide 62 guides the magnetic impact rod 3.

[0020] A cover 2 is fastened to the top of the guide structure, and the cover 2 and the guide structure are fixed together by a snap-fit ​​structure. Specifically, in some embodiments, the snap-fit ​​structure includes a triangular wedge 61 disposed on the outside of the guide structure 6 and a groove 21 disposed on the inside of the cover 2. When the cover 2 is fastened to the guide structure, the triangular wedge 61 can be inserted into the groove 21. In some other embodiments, the triangular wedge 61 can also be made into a rectangular wedge.

[0021] The magnetic impact rod 3 is made of iron. The wires wound on the support are energized to generate a magnetic field force, which pushes the impact rod to move along the P direction. A conical needle is set at its front end. When the magnetic impact rod 3 moves downward, it can pass through the hole 112 in the bottom plate and thus break the glass.

[0022] As a preferred embodiment, the inner side of the base plate 11 is provided with a triangular groove 111 for the wires to be led out.

[0023] Please refer to Figure 3 , Figure 4 As a preferred embodiment, the outer periphery of the electromagnetic coil 4 is provided with a shell 8 that protects the electromagnetic coil.

[0024] As a preferred embodiment, in order to avoid accidental activation of the switch in non-emergency situations, the switch is provided with an anti-accidental activation structure. The anti-accidental activation structure includes a surrounding plate 92 that surrounds the switch 10 and is open at the top, and a puncturable film disposed at the top of the surrounding plate 92. In an emergency, the film can be punctured to operate the switch 10.

[0025] Please refer to Figure 5 As a preferred embodiment, in some embodiments, to further avoid accidental damage, a pin safety structure 7 can be installed at the bottom of the base plate 11. The pin safety structure 7 includes a pin disc 71 fixedly connected to the bottom of the base plate 11, and the lower end face of the pin disc 71 is fixedly connected to the car glass. The pin disc 71 has a safety hole 72 in the middle, which is connected to the hole 112 in the base plate. When the conical needle impacts downward, it can pass through the hole 112 in the base plate and the safety hole 72 in sequence and break the glass. At the same time, a sliding groove is provided in the middle of the interior of the pin disc 71, and a pin plate 73 that can slide left and right is provided in the sliding groove. In non-emergency situations, the pin plate 73 can close the safety hole 72. At this time, even if the conical needle impacts downward, the safety hole 72 can protect the glass. In an emergency, the pin plate 73 can be pulled out (preferably, the pulling direction can be designed to face upward to prevent it from easily slipping). At this time, pressing the button will allow the glass to be broken normally by the conical needle.

[0026] As a preferred embodiment, in some embodiments, to improve the reliability of the device, at least one LED indicator facing the occupant area is integrated on the outer surface of the cover; at the moment of power-on, the DC resistance of the coil is detected by a sensor and the detected value is compared with a preset threshold. When the parameter exceeds the allowable deviation range, the LED flashes continuously to indicate replacement or maintenance, thereby enabling the remaining life of the window breaker to be intuitively known without disassembly.
