[0016] Beneficial effects:

[0017] 1. For this automatic window-breaking device for an automobile, in order to avoid the situation that the glass is not broken at one time, the front mounting frame and the rear mounting frame are installed on the top of the inner wall of the automobile near the alarm by bolts, so that when the automobile tilts at 60 degrees, the alarm will sound, and the window-breaking device will receive the signal to start the reduction motor, so that the gear rotates. The gear meshes with the external teeth arranged on the top of the rack, so that the rack can move inside the limiting groove, and the rack will compress the spring, which will cause the rack to contract and accumulate energy inside the limiting groove. The gear is arranged in a semi-gear shape, so when the toothless part of the gear contacts the rack, the energy accumulated by the rack will be released, and the tungsten steel needle will quickly impact the car window. The setting of the reduction motor can enable the tungsten steel needle to continuously break the car window, which can effectively and quickly break the glass.

[0018] 2. For the automotive automatic window-breaking device, to avoid gear rattle between the gear and the rack due to different positions of the rack, when the reduction motor starts and the gear rotates, a left outer tooth on the outer surface of the gear will contact an outer tooth near the spring at the top of the rack. When the gear rotates, the right outer tooth will mesh with an outer tooth near the tungsten steel needle on one side of the movable slot. This enables the gear to rotate and drive the rack to compress the spring until the last outer tooth of the gear. When the gear runs to the empty tooth position, the rack drives the tungsten steel needle to release and impact the window. The setting of the movable slot can effectively avoid gear rattle caused by different positions of the rack during the next meshing of the gear and the rack. Description of the Drawings

[0024] As Figures 1 - 4 shown, the present utility model provides a technical solution: an automotive automatic window-breaking device, including a base body 1. A mounting bracket hole 11 is provided on one side of the base body 1. A front mounting bracket 2 is provided on one side of the base body 1. A rear mounting bracket 3 is provided on the other side of the base body 1. A window-breaking device is provided on the top of the base body 1. The window-breaking device includes a limit groove 7, a rack 9, a tungsten steel needle 10, a spring 8, a motor mounting hole 12, a motor bracket 4, a reduction motor 5, and a gear 6.

[0025] In an embodiment of the present utility model, a limiting groove 7 is provided at the top of the base body 1. The limiting groove 7 runs through one side of the front mounting frame 2. The size of the limiting groove 7 is adapted to the size of the rack frame 9, which enables the rack frame 9 to move inside the limiting groove 7. The rack frame 9 is clamped inside the limiting groove 7. The rack frame 9 is arranged in the shape of a special-shaped block. An activity groove 13 is provided on the upper surface of the rack frame 9. The size of the activity groove 13 is adapted to the size of the three external teeth provided on the outer surface of the gear 6. In this way, one left external tooth provided on the outer surface of the gear 6 can be in contact with the external tooth near the spring 8 at the top of the rack frame 9. When the gear 6 rotates, the right external tooth will be engaged with the external tooth near the tungsten steel needle 10 on one side of the activity groove 13. This enables the gear 6 to rotate and drive the rack frame 9 to compress the spring 8 until the last external tooth of the gear 6. When the gear 6 runs to the toothless position, the rack frame 9 drives the tungsten steel needle 10 to release and impact the car window. The setting of the activity groove 13 can effectively prevent the gear 6 from engaging with the rack frame 9 for the next time and causing gear jamming due to the different positions of the rack frame 9.

[0026] Meanwhile, a tungsten steel needle 10 is provided at one end of the rack frame 9, and a spring 8 is provided at the other end of the rack frame 9. A motor mounting hole 12 is provided at the top of the base body 1. A motor bracket 4 is provided at the top of the base body 1. The motor bracket 4 is arranged in an L shape. The position of the motor bracket 4 is adapted to the size of the reduction motor 5 and the size of the base body 1. A gear 6 is provided on one side of the vertical part of the motor bracket 4, which enables the gear 6 to mesh well with the rack frame 9. A reduction motor 5 is fixedly connected to one side of the motor bracket 4. The output end of the reduction motor 5 is fixedly connected with a gear 6. The gear 6 is arranged in the shape of a semi-gear. Four external teeth are provided on the outer surface of the gear 6. The position of the gear 6 corresponds to the position of the rack frame 9. The gear 6 meshes with the rack frame 9, which enables the gear 6 to drive the rack frame 9 to move when rotating. The gear 6 meshes with the external teeth provided at the top of the rack frame 9. In this way, the rack frame 9 can move inside the limiting groove 7, and the rack frame 9 will compress the spring 8. This will cause the rack frame 9 to contract and accumulate energy inside the limiting groove 7. And when the toothless part of the gear 6 comes into contact with the rack frame 9, the energy accumulated by the rack frame 9 will be released, allowing the tungsten steel needle 10 to quickly impact the car window. The setting of the reduction motor 5 enables the tungsten steel needle 10 to continuously break the car window, which can effectively deal with the situation where the glass is not broken at one time.

[0027] In the present utility model, during use, the front mounting bracket 2 and the rear mounting bracket 3 are installed on the top of the inner wall of the vehicle near the alarm by bolts. In this way, when the vehicle tilts at an angle of sixty degrees, the alarm is triggered to emit an alarm, which causes the window-breaking device to receive a signal and start the reduction motor 5, thereby causing the gear 6 to rotate. The gear 6 meshes with the external teeth provided at the top of the rack 9, so that the rack 9 can move inside the limit slot 7, and the rack 9 will compress the spring 8, which will cause the rack 9 to contract and accumulate force inside the limit slot 7. The gear 6 is a semi-gear. Therefore, when the toothless part of the gear 6 contacts the rack 9, the force accumulated by the rack 9 will be released, allowing the tungsten steel needle 10 to quickly impact the vehicle window. The setting of the reduction motor 5 enables the tungsten steel needle 10 to intermittently break the vehicle window, which can effectively deal with the situation where the glass is not broken at one time.

[0028] Further, when the reduction motor 5 starts and the gear 6 rotates, a left external tooth provided on the outer surface of the gear 6 will contact the external teeth at the top of the rack 9 near the spring 8. When the gear 6 rotates, the right external tooth will mesh with the external teeth on one side of the movable slot 13 near the tungsten steel needle 10. This can cause the gear 6 to rotate and drive the rack 9 to compress the spring 8 until the last external tooth of the gear 6. When the gear 6 runs to the toothless part, the rack 9 drives the tungsten steel needle 10 to release and impact the vehicle window. The setting of the movable slot 13 can effectively prevent the gear 6 and the rack 9 from jamming due to the different positions of the rack 9 during the next meshing.

[0029] The above text generally describes the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
