Detailed Description

The following specific examples are given by way of illustration only and not by way of limitation, and it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made in the examples without inventive faculty, and yet still be protected by the scope of the claims.

The scheme is realized by the following technical means:

example (b): an escape window breaking device comprises a steel cylindrical outer shell 3, wherein the inner part of the outer shell 3 is hollow and is opened at one end position, and a hollow inner cavity part 3a which is also cylindrical is formed. In the hollow inner chamber portion 3a, a steel columnar rod member is inserted as a primary impact crushing member 1 for performing a collision crushing treatment on the glass window in a window breaking process. The primary impact crushing member 1 is integrally formed by die casting, the main body portion 1a thereof has a cylindrical shape similar to the hollow inner chamber portion 3a but slightly smaller than the hollow inner chamber portion 3a, and the impact portion 1b at the front end thereof has a conical shape with the tip of the cone directed to the outside of the hollow inner chamber portion 3 a. A long-strip-shaped steel rod piece is fixedly installed on the outer side of the primary impact crushing piece 1 in a hinged mode to serve as a secondary extrusion flaring piece 2, the secondary extrusion flaring piece 2 is hinged with the primary impact crushing piece 1, the front portion of the primary impact crushing piece 1 is located at the hinged position of the primary impact crushing piece 2, and the secondary extrusion flaring piece 2 can rotate around a hinged center. A driving structure 4 for driving the secondary extrusion flaring piece 2 to rotate is arranged at the hinged position, and the main component of the driving structure 4 is a torsion spring 4a, one end of the torsion spring is fixed on the secondary extrusion flaring piece 2, and the other end of the torsion spring is fixed on the primary impact crushing piece 1. The bottom position of the hollow inner cavity part 3a is also provided with a composite firing assembly 5 which is provided with an escape window breaking device for providing impact and extrusion power, and the composite firing assembly 5 mainly comprises a secondary firing structure 5b close to the inner side and a primary firing structure 5a close to the outer side. Specifically, the main part of the primary percussion structure 5a is a compression spring, one end of the compression spring is connected with the bottom surface of the hollow inner cavity part 3a in an abutting mode, and the other end of the compression spring is connected with the bottom surface of the primary impact crushing piece 1 in an abutting mode; the secondary triggering structure 5b mainly comprises a gunpowder filling layer and an electric control initiation device.

When the primary impact crushing member 1 and the secondary extrusion flaring member 2 are simultaneously installed in the hollow inner cavity portion 3a of the outer shell 3, the secondary extrusion flaring member 2 is firstly rotated clockwise until the end of the rod member is attached to the outer wall surface of the primary impact crushing member 1, so that the two end portions of the torsion spring 4a are close to each other to be twisted and accumulate potential energy. Then, the first-stage impact crushing piece 1 and the second-stage extrusion flaring piece 2 are pushed inwards from the opening of the outer shell 3 to enter the hollow inner cavity part 3a, the outer side surface of the second-stage extrusion flaring piece 2 abuts against the inner wall surface of the hollow inner cavity part 3a, and the second-stage extrusion flaring piece 2 is prevented from moving; as the primary impact breaker member 1 moves inwardly, the compression spring located within the hollow chamber portion 3a is compressed to accumulate elastic potential energy. When the inner parts are moved to a certain position, the blocking member mounted in the hollow inner chamber portion 3a locks the primary impact breaker member 1 against outward ejection.

When the escape window breaking device works, the locking mechanism 4b releases the locking of the first-stage impact breaking piece 1, potential energy accumulated by the compression spring is released instantaneously and pushes the first-stage impact breaking piece 1 to pop out, the conical front end of the first-stage impact breaking piece 1 impacts the window glass, and the single-point collision forms great pressure at a contact position and breaks the glass at the contact position. Simultaneously at this in-process, second grade extrusion flaring spare 2 moves to the outside of cavity inner chamber portion 3a until breaking away from completely following the one-level striking crushing spare 1 as the main part, and the inner wall of cavity inner chamber portion 3a no longer produces the effect of leaning on to second grade extrusion flaring spare 2 at this moment, and under torsion spring 4 a's effect, be rodlike second grade extrusion flaring spare 2 and rotate and outwards open and lean on the laminating until tip and window glass counterbalance. At this time, the electric control initiation device in the secondary firing structure 5b receives signals and ignites the gunpowder filling layer, and the gunpowder in the hollow cavity part 3a rapidly and violently burns to generate a large amount of heat, so that the air in the cavity rapidly expands and generates strong pushing acting force for the primary impact crushing piece 1. At this moment, the one-level impact crushing piece 1 and the two-level extrusion flaring piece 2 act on the car window glass to extrude towards the outside at multiple points, and the glass crushing point is expanded to form a larger opening at the primary breakdown position, so that the process that personnel need to manually carry out secondary window breaking when passing through is omitted, the escape time is greatly shortened, and the escape condition is more favorable for vehicle passengers.

Preferably, a locking mechanism 4b is arranged at the position where the primary impact crushing member 1 and the secondary extrusion flaring member 2 are hinged, and the locking mechanism can prevent the secondary extrusion flaring member 2 from reversely rotating around the hinge center due to the large acting force of the glass on the secondary extrusion flaring member during the secondary firing process. Specifically, the locking structure comprises a one-way ratchet wheel arranged at the hinged position of the secondary extrusion flaring piece 2 and a swing rod arranged on the primary impact crushing piece 1, and the rotation direction of the teeth of the one-way ratchet wheel is opposite to the rotation direction of the secondary extrusion flaring piece 2 when the secondary extrusion flaring piece is outwards popped. When the one-way ratchet wheel rotates by one gear tooth, the swing rod is embedded into the next tooth groove and continues until the secondary extrusion flaring piece 2 completely abuts against the surface of the window glass and does not move any more. In the process of secondary triggering, the swinging rod is inserted between the gear teeth of the ratchet wheel to play a role in locking the reverse rotation of the ratchet wheel, so that the strength of the secondary extrusion flaring piece 2 and the destructive acting force generated on glass by the secondary extrusion flaring piece are greatly improved.

Preferably, a sealing filler 6 is further installed on the primary impact crushing member 1, and the sealing filler 6 is a rubber sealing ring, and the inner and outer side surfaces of the sealing filler 6 are respectively closely attached to the outer wall surface of the primary impact crushing member 1 and the inner wall surface of the hollow inner cavity portion 3 a. This sealed filling member 6 can effectively prevent inside heat and gaseous outside the emergence escape from the clearance department of two parts when escaping broken window device second grade percussion, guarantees inside powerful effort that produces, effectively optimizes broken window effect.
