[0026] Example 1
[0027] like Figure 1-5As shown, the window-breaking escape device of this embodiment includes a hand-operated decorative plate 1 and a push plate 5 arranged in the space between the door guard plate 9 and the door glass 100. The hand-operated decorative plate 1 is provided with an ejector groove, and the inner wall of the ejector groove is provided with a first limiting rib 11 and a second limiting rib 12, and the second limiting rib 12 is located at the rear end of the first limiting rib 11. The ejector 2 is arranged in the ejector groove of the hand-operated decorative plate 1. The front end of the ejector 2 is provided with an ejector needle tip 21, and the ejector needle tip 21 is arranged adjacent to the glass 100. A limiting ring 22 is arranged on the outer wall of the ejector 2, and the limiting ring and the ejector 2 are an integrally formed structure. The limiting ring 22 cooperates with the second limiting rib 12, and the second limiting rib 12 is located at the rear end of the limiting ring 22. The outer wall of the ejector 2 is also sleeved with a first shaft elastic retaining ring 4, and a return spring 3 is arranged on the outer wall of the ejector between the first shaft elastic retaining ring 4 and the limiting ring 22. The push plate 5 includes a push plate body 51 and a sleeve 52. The side wall of the sleeve 52 is provided with a sliding groove 53 along the length direction of the sleeve, and the front end of the sliding groove 53 is provided with a fixed slot. The rear end of the ejector pin 2 is inserted into the sleeve 52 of the push plate 5, and the push plate pin 7 passes through the sliding groove 53 and the ejector pin 2 and is fixed by the second shaft elastic retaining ring 6. The door guard plate 9 is provided with a blocking cover 8, which covers the opening of the buckle decorative plate 1 to block the ejector pin 2.
[0028] The assembly process of the broken window escape device of this embodiment is as follows:
[0029] 1. First, place the plug cover on the door guard plate, install the return spring on the ejector pin, and install the first shaft on the ejector pin with a circlip;
[0030] 2. After assembling the above three parts, put them into the ejector pin groove of the handle trim from the glass side, with the tip of the ejector pin on the glass side;
[0031] 3. Install the push plate from the other side. To prevent the push plate from falling off, fix it with the push plate pin and the elastic retaining ring of the second shaft.
[0032] Open the plug cap when using. Figure 6-7 As shown in the figure, pull out the push plate, rotate it to a certain angle, lock the push plate pin in the fixed slot of the push plate, and then push the push plate hard to break the glass.
[0033] In this embodiment, the second limiting rib 12 and the first axis elastic retaining ring 4 limit the movement distance of the return spring 3, the first axis elastic retaining ring 4 cooperates with the second limiting rib 12 to prevent the ejector 2 from popping out of the buckle plate 1 due to elastic force, and the push plate 5 is installed on the ejector 2 through the push plate pin 7 and the second axis elastic retaining ring 6 to prevent the push plate 5 from falling off. When pushing, the first limiting rib 11 provides resistance, and the first limiting rib 11 is deformed under the action of the thrust, and breaks away from the first limiting rib 11 in an instant, giving the ejector needle tip 21 speed and inertia. The ejector needle tip 21 contacts the glass 100 under the action of inertia, causing uneven stress in the glass, thereby breaking the glass 100.
[0034] When a drowning accident occurs, the window-breaking escape device of this embodiment can easily break the glass due to the pressure difference between the inside and outside of the cabin, and quickly balance the pressure difference between the inside and outside, open the door, and escape in time. Since the device of this embodiment is directly installed on the door, it is not easy to be lost, which improves the safety of the occupants and the survival rate of escape.
