Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to a grille anti-theft device. Background Art

[0002] The car grille is one of the key elements of modern car design. It not only enhances the appearance of the vehicle, but also plays a role in protecting the engine compartment and dissipating heat. With the rapid development of the automobile market and the advancement of technology, more and more consumers are paying attention to the safety and anti-theft performance of the car. However, most traditional car grilles are installed in a simple snap-on manner. Although this installation method is easy to replace and maintain, it also makes it easy to become a target of theft, causing economic losses and safety hazards to car owners.

[0003] To address this problem, there are some common solutions on the market. For example, some vehicles use anti-dismantling screws or anti-dismantling buckles to install the grille, and some vehicles are equipped with special physical locks, such as padlocks or chains, to prevent the grille from being separated from the body after being removed, thereby enhancing the protective effect; in addition, some high-end models have even introduced anti-dismantling alarm devices. These methods have their own characteristics, but there are still certain shortcomings in practical applications. Anti-dismantling screws and anti-dismantling buckles make it impossible to remove the grille during repair and maintenance, and forced removal will cause damage to the grille; padlocks and chains can be shortened and destroyed with simple shearing tools; anti-dismantling alarm devices can only sound an alarm and cannot prevent the grille from being removed.

[0004] In addition, after long-term use, dust easily accumulates on the grille, blocking the grille's ventilation holes, affecting the heat dissipation effect of the engine compartment. It is usually necessary to manually clean or replace the filter regularly, but these methods are inefficient and difficult to achieve automated cleaning.

[0005] Therefore, how to effectively improve the anti-theft performance of the grille and reduce the problem of ventilation hole blockage has become a technical problem that needs to be solved urgently. Summary of the invention

[0006] In order to improve the anti-theft performance of the grille and reduce the problem of ventilation hole blockage, the present application provides a grille anti-theft device.

[0014] By adopting the above technical solution, when the grille anti-theft device is powered on, the telescopic drive member retracts and the card block disengages from the card slot, which does not affect the normal sliding of the rack and the reciprocating rotation of the rotating rod, thereby ensuring that the cleaning rod can smoothly swing in the ventilation hole to perform dust removal operations; when the vehicle body is powered off, the telescopic drive member extends out, the card block is carded into the card slot, preventing the rack from sliding, thereby keeping the rotating rod in a locked state, and the locking block is inserted into the locking hole, preventing the locking block and the locking hole from being unlocked by prying the cleaning rod.

[0022] By adopting the above technical solution, when the vehicle suffers a slight collision, the buffer assembly can effectively absorb the impact force and avoid damage to the grille caused by excessive support of the cleaning rod; specifically, when the impact force acts on the rotating rod, the cleaning rod will shrink into the buffer tube, and the second elastic member will compress and store energy, thereby alleviating the transmission of the impact force; after the impact force disappears, the second elastic member releases the energy and pushes the cleaning rod to return to its original position.

[0023] Optionally, a limiting ring is provided at one end of the buffer cylinder away from the rotating rod, and a limiting block is provided at one end of the cleaning rod located in the buffer cylinder.

[0025] Optionally, a rubber pad is provided on one side of the cleaning rod for cleaning dust in the ventilation hole.

[0026] By adopting the above technical solution, the rubber pad can increase the friction between the cleaning rod and the inner wall of the ventilation hole, thereby more effectively removing dust and dirt attached to the ventilation hole and improving the cleaning effect; at the same time, the rubber material has good flexibility and wear resistance, and can maintain a good shape and function during multiple uses, thereby extending the service life; in addition, the rubber pad can also reduce noise during the cleaning process and improve the user experience.

[0027] In summary, this application includes the following beneficial technical effects: 1.

[0046] The implementation principle of a grille anti-theft device in the embodiment of the present application is as follows: the grille anti-theft device realizes both anti-theft and automatic cleaning functions by combining a unique locking dust removal component 1 and a driving device 2. When the vehicle is driving, wind energy is converted into mechanical energy through the fan blades 225, driving the rotating rod 11 to rotate back and forth, thereby driving the cleaning rod 12 to swing in the ventilation hole 300 to achieve the effect of automatic cleaning; at the same time, when the rotating rod 11 swings to the first side of the ventilation hole 300, the locking block 121 is plugged into the locking hole 201, effectively preventing the grille 200 from being illegally removed; this design not only improves the anti-theft performance of the grille 200, but also significantly reduces the problem of clogging of the ventilation hole 300, prolongs the service life of the grille 200, and improves the overall safety and reliability of the vehicle. In addition, the setting of the backstop assembly 3 makes it possible for the telescopic drive member 31 to retract and the snap-in block 32 to disengage from the snap-in groove 2121 when the vehicle is in the starting state. At this time, the rack 212 can slide freely and the rotating rod 11 can rotate freely, so as to facilitate cleaning of dust in the ventilation hole 300. When the vehicle is turned off, the telescopic drive member 31 is extended and the snap-in block 32 is snapped into the snap-in groove 2121 to prevent the rack 212 from sliding, thereby preventing the locking block 121 and the locking hole 201 from being unlocked by rotating the rotating rod 11. This design further enhances the anti-theft performance of the grille 200, ensuring that the grille 200 remains locked when the vehicle is stopped, thereby reducing the risk of theft. By adding the buffer assembly 4, the working performance of the cleaning rod 12 is improved; when the rotating rod 11 drives the cleaning rod 12 to swing in the ventilation hole 300, the second elastic member 42 can reduce the hard collision of the cleaning rod 12 with the ventilation hole 300, thereby extending the life of the cleaning rod 12; at the same time, it can effectively absorb the impact force when the vehicle suffers a slight collision, avoiding damage caused by excessive support of the cleaning rod 12 to the grille 200. The cooperation of the limiting ring 411 and the limiting block 122 can prevent the cleaning rod 12 from being overextended and falling off, ensuring that it always works within an effective range. Finally, by arranging a rubber pad 6 on one side of the cleaning rod 12, its cleaning effect is further improved. The soft characteristics of the rubber pad 6 enable it to fit tightly on the inner wall of the ventilation hole 300, effectively removing accumulated dust and impurities.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
