Problems solved by technology

Obviously, the automatic window breaker can be triggered remotely, and also has the local trigger function of the manual window breaker. However, the electric trigger window breaker uses an electromagnetically controlled window breaker, which has the problem of insufficient force. On the one hand, the local switch is also electronically controlled. If the car enters water and causes the window breaker to fail, there is no more secure backup trigger method

Embodiment 1

[0027] What the present invention discloses is an automatic window breaking device, such as Figure 1-2 As shown, it is a preferred embodiment of the present invention. The window breaking device includes an impact seat 2 fixedly installed on the tempered glass 1 and an actuation box 3 fixedly connected with the impact seat 2. The actuation box 3 is installed on the impact seat 2. At one end away from the tempered glass 1, a first through hole 21 is provided in the impact seat 2, and an impact rod 4 is slidably installed in the first through hole 21, and an impact head 41 is fixedly connected to the first end of the impact rod 4 close to the tempered glass 1; The actuating box 3 is a hollow structure, which can be formed by airtight splicing of multiple box bodies through sealing strips, thereby ensuring the waterproof performance of the actuating box 3 . An actuating mechanism is installed in the actuating chamber 30 inside the actuating box 3, and the first through hole 21 c...

Embodiment 2

[0032] The difference between this embodiment and embodiment one is that the actuating mechanism of the automatic window breaking device is different, such as Figure 3-4 As shown, what this embodiment adopts is the motor 6 whose output shaft is fixedly connected with the threaded mandrel 61 , and the threaded mandrel 61 is driven by the motor 6 to rotate around the axis. In order to adapt to the actuating mechanism, a second through hole 22 parallel to the first through hole 21 is also provided in the impact seat 2, and the second through hole 22 is also communicated with the actuating chamber 30; The guide rod 7, the two ends of the guide rod 7 are supported and positioned by the second positioning head 26 installed at the two ends of the second through hole 22; , making the mutual restriction between the two. Matched, the second end of the impact rod 4 is a sleeve 46 with a thread inside, the sleeve mouth is welded on the connecting rod 8 and a through hole 81 is opened at...

Abstract

The invention discloses an automatic window breaking device. The automatic window breaking device comprises a striking seat fixedly mounted on tempered glass and an actuating box fixedly connected with the striking seat, wherein a first through hole is formed in the striking seat, a striking rod is slidably mounted in the first through hole, a striking head is fixedly connected to the first end, close to the tempered glass, of the striking rod, the actuating box is a hollowed structure, an actuating mechanism is mounted in an actuating cavity inside the actuating box, the first through hole communicates with the actuating cavity, the actuating mechanism converts rotation into pushing force, the pushing force points to the tempered glass and pushes the striking rod to enable the striking head to act on the tempered glass, the device reduces the requirement on a striking stroke of the striking head, reduces the size of the window breaking device, and guarantees that the striking head hasenough striking force to smoothly break the tempered glass.

Description

technical field [0001] The invention relates to a window breaker for vehicles, in particular to an automatic window breaker. Background technique [0002] In recent years, the public has paid more and more attention to the emergency escape of vehicles, and people have put forward higher and higher requirements for the comfort and safety of vehicles, especially large passenger cars carrying a large number of passengers. For a long time, we have equipped large buses with safety hammers. When a vehicle accident occurs, if the windows and doors of the bus cannot be opened due to accidents such as water soaking or burning, passengers can remove the safety hammer. He escaped by smashing a car window. However, in the process of application, it is found that the traditional safety hammer still has certain shortcomings. First, passengers may fail to notice the safety hammer due to nervousness or lose consciousness and cannot use the safety hammer when an accident occurs. Secondly, t...
