Description

Window breaking device

technical field

The invention relates to a public safety device, in particular to a vehicle window breaking device.

Background technique

At present, the vehicle window breaking device is mainly installed near the vehicle window in the form of a percussion blasting hammer, which is easy to lose. There have been palm-slap blasting hammers and directional automatic blasting devices in China. These blasting devices are easy to be stolen, and the use efficiency of blasting hammers is not high. The cost of automatic directional blasting devices is high, and it is not easy to cover all car windows. . Chinese patent CN101565029A discloses a pre-assembled automobile glass safety hammer, which belongs to the palm-type blasting hammer. The elastic bowl of this blasting hammer is pre-installed on the glass. The tip of the metal hammer faces the glass. Hit the cover. Although this kind of safety hammer is directly pre-installed on the glass, although it is not easy to lose, it is easy to block the view of the glass, and it can only be hit at a single point. In addition, the tip of the metal hammer is always facing the glass, so it is easy to cause misuse, cause unnecessary losses, and even cause unnecessary panic among the public.

detailed description

The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.

Taking the bus as an example, the window breaking device of this embodiment is installed in a hidden groove on the top of the window. This groove can be a recess on the car body, or a plastic with a U-shaped cross section. The groove (omitted in the figure), its purpose is to hide the broken window device, so that it is not exposed to the normal line of sight. The car window breaking device comprises a hammer head 11 and a hammer handle 14, the hammer head 11 is a shell structure, including a shell 10, the shell 10 is provided with a first spring 2 and a second spring 16, along the upper end surface of the hammer head 11 to The lower end surface is followed by the palm button 1, the impact hammer 5 fixed at the center of the palm button 1, the first spring 2 arranged on the periphery of the hammer 5, the hammer head impact plate 7, and the impact hammer fixed at the center of the hammer head impact plate 7. Hammer 8, the second spring 16 set on the outer periphery of impact hammer 8, a first stroke is provided between impact hammer 5 and hammer head impact plate 7, and a second stroke is provided between impact hammer 8 and the lower end surface of hammer head 11. The outside of the palm button 1 is also provided with a casing 3, an outer cushion 4 is arranged between the casing 3 and the upper end surface of the hammer head 11, and an inner cushion 4 is arranged between the impact hammer 5 and the hammer head impact plate 7. On the hammer handle 14, a lock pin 13 and a lock ring 12 cooperating with the lock pin 13 are provided near the front end. The locking pin 13 is electrically connected. Since the sensing system is a mature technology, its detailed structure will not be described in detail. The sensing system can prompt the locking pin 13 to be released from the locking ring 12 when the vehicle is subject to a major impact or rollover. And the lock ring 12 is fixed on the second installation position, and the position near the rear end on the hammer handle 14 is provided with a rotating connection device 15, and the hammer handle 14 is rotatably fixed on the first installation position by the rotation connection device 15, and the first When the installation position makes the hammer handle 14 rotate, the hammer head 11 can face more than one position on the window plane. The position of the non-window plane of the bus does not block the windows and is not easy to be misoperated. The simplest mode of the rotating connection device 15 wherein may be to set a hole on the hammer handle 14, and a pin shaft passing through the hole, and the pin shaft is fixed in the hidden groove. A resistance ring can be provided between the hole and the pin shaft. When the lock pin 13 is released, the hammer handle 14 can slowly rotate around the fulcrum and fall down.

In addition, the palm button 1 is provided with a button warning light, which is electrically connected to the sensing system, and the sensing system controls the flashing and extinguishing of the button warning light. When the car body is subject to specific impacts and other accidents, the warning light of the button that the window breaking device automatically drops will flash, reminding passengers to hit the palm button 1 to break the window to save themselves.

Therefore, the above-mentioned window breaking device, under normal circumstances, the whole device is connected to the inner wall of the carriage because of the rotating connecting device 15, and the lock ring 12 buckles the locking pin 13, so that the window breaking device is horizontally locked at the hidden position on the top of the window. Does not block the window view. When an accident occurs, the sensing device in the hammer handle 14 causes the lock pin 13 to be unclamped, and the window breaking device swings down with the position of the rotating connection device 15 as the fulcrum. At the same time, the button warning light emits a red warning light to attract the attention of passengers and warn of safety. After the window breaking device is placed, when the passenger slaps the button 1 with his palm, the impact hammer 5 reaches the lowest point after a certain stroke because of the elastic compression of the first spring 2 and the second spring 16, and the outer cushion 4 slows down. After the device itself compresses the impact force, it prevents the device from being damaged due to excessive impact force. Similarly, the inner cushion 6 can also slow down the destruction of the hammer shell 10 under the action of a huge impact force. After the impact hammer 5 hits the hammer head impact plate 7 after the stroke, the impact hammer 8 quickly passes through the hammer hole 9 to impact and break the vehicle window. When the window breaking device is placed down, it can rotate multiple fixed points and strike to realize multi-point blasting of the car window, accelerate the destruction of the car window, and ensure personal safety.

As one of the embodiments, the following parameters can be selected: the inner height of the hammer head is 27mm, the outer diameter is 70mm, the diameter of the spring wire is 3mm, the pitch is 7.5mm, and the spring with 3 coils is selected. In this case, as long as the external force is 70N, the maximum compression amount of 12.5mm can be achieved, and a huge impact force will be generated immediately after a 1cm stroke to shatter the glass. In addition, the impact hammer 8 is made of high-hardness alloy, and its cone head adopts a 60° angle cone head, which ensures the stability of the cone head under huge impact force. Hammer handle 14 can adopt PVC plastics

What is disclosed above is only the preferred embodiment of the present invention, which certainly cannot limit the right scope of the design of the present invention. Therefore, equivalent changes made according to the patent scope of the design of the present invention still fall within the scope of the present invention.
