[0026] When blade 2 is closed in air inlet grille body 1, the upper pushing force of spring return rod 6 is applied to support block 7 and first magnetic attraction block 9, first magnetic attraction block 9 will be pressed against the lower end of first magnet block 4, and first magnetic attraction block 9 will be adsorbed by first magnet block 4, so that blade 2 is stably closed in air inlet grille body 1, and second magnet block 11 is adsorbed to second magnetic attraction block 12 by magnetic force, which is beneficial to better improve the stability of blade 2 when closing, and in summary, it is beneficial to prevent blade 2 from being automatically opened, so as to avoid problems such as pressing loose, abnormal sound and appearance defect of blade 2.

[0027] The alarm 23 is mounted on the top of the air intake grille body 1, and the mounting groove 10 is formed on the inner side wall of the air intake grille body 1 near the lower side of the first magnet block 4. The alarm starting assembly is arranged in the mounting groove 10, and the alarm starting assembly comprises the partition plate 13, the pressing plate 21, the return spring 16, the pressing rod 15, the pressing ball 14, the electromagnet 17, the magnetic iron sheet 18, the positive electrical terminal 19 and the negative electrical terminal 20. The partition plate 13 is fixed in the mounting groove 10, the pressing plate 21 is located on the right side of the partition plate 13, the return spring 16 is connected between the right side of the pressing plate 21 and the inner side wall of the mounting groove 10, the pressing rod 15 is fixed on the left side of the pressing plate 21, the pressing rod 15 is slid to the left and penetrates through the partition plate 13, the pressing ball 14 is fixed on the left end of the pressing rod 15 and extends out of the mounting groove 1, the blade 2 is abutted on the left side of the pressing ball 14, the electromagnet 17 is fixed on the inner side wall of the mounting groove 10, the magnetic iron sheet 18 is connected on the right side of the pressing plate 21, the electromagnet 17 and the magnetic iron sheet 18 are correspondingly arranged on the left and right sides, the positive electrical terminal 19 is connected on the right side of the partition plate 13, the negative electrical terminal 20 is connected on the left side of the pressing plate 21, the positive electrical terminal 19 and the negative electrical terminal 20 are correspondingly arranged on the left and right sides, and the positive electrical terminal 19 is connected with the alarm 23 in series.

[0028] As shown in the drawings, Figures 3-6 When the blade 2 is accidentally opened due to excessive external pressure, the switch 22 is closed and the electromagnet 17 is not energized, so the electromagnet 17 cannot attract the magnetic iron sheet 18. Under the condition that the electromagnet 17 is in contact with the magnetic iron sheet 18, the return spring 16 is arranged to be compressed by the pressing plate 21. Once the blade 2 is accidentally opened counterclockwise, the blade 2 no longer presses the pressing ball 14, and the pressing plate 21, the pressing rod 15 and the pressing ball 14 are pushed to the left by the elastic force of the return spring 16. The pressing plate 21 drives the negative electrical terminal 20 to contact the positive electrical terminal 19. At this time, the power of the internal power supply of the automobile is transmitted to the alarm 23 through the negative electrical terminal and the positive electrical terminal 19. The alarm 23 is started to emit an alarm sound, so as to timely remind the driver and passenger that the blade 2 is accidentally opened, so as to avoid the problem that the blade 2 is accidentally opened and cannot be found in time. The driver and passenger can timely adjust the blade 2 to be closed, so as to prevent the normal running condition of the automobile from being affected, and to ensure the normal driving state.

[0029] As shown in the drawings, Figures 3-6 In the embodiment, the air intake grille body 1 is provided with the switch 22, and the switch 22 is connected with the electromagnet 17 in series.

[0030] When the blade 2 is normally opened counterclockwise, in order to prevent the alarm 23 from sounding accidentally, the switch 22 is installed on the front of the console in the car, and the driver can energize the electromagnet 17 in advance through the switch 22. When the electromagnet 17 is energized, it will be attracted to the magnetic sheet 18 by magnetic force. Under the premise that the negative terminal 20 is electrically connected to the internal power supply of the car, the positive terminal 19 will not be in contact with the negative terminal 20 to be energized. Therefore, when the blade 2 is normally opened, the alarm 23 will not sound an alarm, which helps to avoid false alarms.

[0031] As shown in Figures 3-6 the first recess 3 is provided in the upper end of the inner wall of the air intake grille body 1, the first magnet block 4 is connected to the first recess 3, the second recess 5 is provided in the upper end of the inner side of the blade 2, the spring return rod 6 is fixed in the second recess 5, the support block 7 is connected to the upper end of the spring return rod 6, the first magnetic block 9 is fixed to the upper end of the support block 7, the through hole 8 is provided in the upper end of the blade 2 and communicates with the second recess 5, the first magnetic block 9 extends out of the upper surface of the blade 2 through the through hole 8, and the first magnetic block 9 is attracted to the first magnet block 4 by magnetic force, and the upper right end of the first magnet block 4 is inclined.

[0032] When the opened blade 2 needs to be closed in the air intake grille body 1, the blade 2 is rotated clockwise to reset. During this process, the first magnet block 4 will push the first magnetic block 9 upward along the inclined surface of the first magnetic block 9, and the first magnetic block 9 will drive the support block 7 to compress the spring return rod 6 downward. When the second magnetic block 11 attracts the second magnetic block 12, the blade 2 presses the ball 14, the negative terminal 20 is driven away from the positive terminal 19 by the pressing plate 21, the electromagnet 17 is in contact with the magnetic sheet 18, and the pressing plate 21 compresses the return spring 16. The spring return rod 6 exerts an upward thrust on the support block 7 and the first magnetic block 9, so that the first magnetic block 9 and the first magnet block 4 are firmly attracted together, which helps to ensure the normal closing of the blade 2.
