This application provides a vehicle safety control device, method, and vehicle. The device includes a collision detection device, a controller, an electronic switch, a relay, and a backup power supply. The collision detection device detects a collision signal and sends it to the controller. Upon receiving the collision signal, the controller determines whether the door lock unlocking conditions are met. If the unlocking conditions are met, the controller activates the electronic switch, which in turn controls the backup power supply to the relay coil to conduct, causing the relay to close. The relay's common contact and normally open contact are connected to the backup power supply and the vehicle's door lock drive device, respectively. When the relay is closed, the normally open contact is connected to the backup power supply, and the electrical signal output by the backup power supply is transmitted to the door lock drive device through the relay to control door lock unlocking. This effectively controls door lock unlocking after a vehicle collision, thereby improving vehicle driving safety.

The utility model provides a peep-proof film convenient for fingerprint unlocking, which comprises a peep-proof film structure, the peep-proof film structure comprises a peep-proof film layer, a use layer and a transparent adhesive layer, the peep-proof film layer is provided with a through hole for exposing a fingerprint identification module or a transparent film is arranged at a position corresponding to the fingerprint identification module on the peep-proof film layer, and the peep-proof film layer is provided with a transparent adhesive layer. The using layer is adhered to the outer side surface of the peep-proof film layer through (optical) transparent glue, and the transparent adhesive layer is adhered to the inner side surface of the peep-proof film layer. According to the peep-proof film facilitating fingerprint unlocking, the through hole or the transparent film is formed in the peep-proof film layer, the fingerprint unlocking function is not affected, the problem that a traditional peep-proof film is difficult in fingerprint unlocking or cannot be unlocked is solved, the peep-proof film not only has the anti-explosion and anti-scraping functions, but also can effectively prevent peeping, meanwhile, the sensitivity of fingerprint unlocking is not affected, and the peep-proof film is convenient to use. The method is suitable for screen protection of electronic equipment such as smart phones and tablet personal computers.

The unlocking equipment comprises a plurality of unlocking ends and flexible transmission parts, each unlocking end comprises a supporting part and an unlocking part, the unlocking parts are arranged on the supporting parts, and the flexible transmission parts are connected with the supporting parts and used for transmitting unlocking power. The unlocking parts are respectively used for acting relative to the supporting parts under the driving of unlocking power and extruding the bolts in the positioning holes through the action so as to drive the bolts to be unlocked; the unlocking equipment provided by the invention is compact in structure, small in size and convenient and flexible to use, not only can unlock the body frame plate, but also can flexibly place the positions of the unlocking ends according to needs so as to correspond to the corresponding plug pins and the positioning holes, so that the unlocking equipment is matched with body frame plates of different models and sizes, different unlocking requirements are met, and the unlocking efficiency is improved. And the universality can be obviously improved.
