DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The vehicle window breaker provides two technical solutions: Figure 1-4 The first embodiment is shown: comprising:

[0026] The window breaking assembly 2 is installed on the mounting base 1 and is used for quickly breaking the front and rear windshields. The window breaking assembly 2 includes three mounting plates 21, and the three mounting plates 21 are fixedly connected to the front of the mounting base 1. An intermediate rod 22 is fixedly connected between the front and rear mounting plates 21, and the intermediate rod 22 passes through the intermediate mounting plate 21. The surfaces of the intermediate rod 22 located between the two mounting plates 21 are sleeved with torsion springs 24. The surface of the intermediate rod 22 is rotatably connected to a U-shaped frame 23. A handle 25 is fixedly connected to the front of the U-shaped frame 23, and a tungsten steel head 26 is fixedly connected to the back of the handle 25. One end of the torsion spring 24 is fixedly connected to the intermediate rod 22, and the other end of the torsion spring 24 is fixedly connected to the inner side of the U-shaped frame 23.

[0027] The limit assembly 3 is arranged on the mounting base 1 and is used to control the breaking force of the window breaking assembly 2. The limit assembly 3 includes an arc plate 31, which is fixedly connected to the front of the mounting base 1. An arc groove 32 is provided inside the arc plate 31. A guide rod 33 is fixedly connected to the top of the U-shaped frame 23, and the guide rod 33 is inside the arc groove 32. An L-shaped plate 34 is fixedly connected to the top of the arc plate 31. A sliding rod 35 is slidably connected to the right side of the L-shaped plate 34. The sliding rod 35 penetrates the L-shaped plate 34 and extends to one end on the left side of the L-shaped plate 34 and is fixedly connected to a limit block 36. A return spring 37 is sleeved on the surface of the sliding rod 35 located between the L-shaped plate 34 and the limit block 36.

[0028] The alarm 4 is embedded and installed at the middle position of the mounting base 1, and the alarm 4 is composed of a display capable of displaying SOS and a speaker, and an opening button is arranged on the alarm 4.

[0029] When it is necessary to break a window, the cooperation between the torsion spring 34 in the window breaking assembly 2 and the limit assembly 3 enables the window breaker to quickly break the glass and ensure the breaking force. After breaking, the alarm 4 can alert people nearby and quickly provide rescue, thereby improving the practicability of the device when in use.

[0030] like Figure 1 and 2 The second embodiment is shown, and the main difference from the first embodiment is that a mounting base 1 is used to mount the window breaker to the front and rear windshields of the car, and the mounting base 1 includes a bottom plate 11, and double-sided tape 12 is pasted on the four corners on the back of the bottom plate 11.

[0031] The window breaker is installed on the front and rear windshields of the car through the installation base 1, which is easy and quick to install, thereby improving the convenience of the device when in use.

[0032] When in use, the shielding object on one side of the double-sided tape 12 is removed privately, thereby fixing the entire device on the front and rear windshields, and the U-shaped frame 23 is rotated by the handle 25, and the U-shaped frame 23 rotates and drives the guide rod 33 to move, and the guide rod 33 moves and contacts the limit block 36 and pushes the limit block 36 to move, so that the guide rod 33 can pass the position of the limit block 36, and after passing, the limit block 36 is reset under the action of the reset spring 37 to limit the position of the guide rod 33. At this time, the window breaking assembly 2 is in a state of waiting to be knocked. When it is necessary to break the window, the sliding rod 35 is pulled by the pull ring to make the limit block 36 move away from the guide rod 33. At this time, the U-shaped frame 23 is rotated and reset under the action of the two torsion springs 24, and then contacts the glass through the tungsten steel head 26, thereby breaking the window, and the alarm 4 is manually started to send out a distress signal.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
