A cable truss, including upper chord cable, lower chord cable, cable clamp, cable clamp support arm, cable end connecting block; the two ends of the cable clamp support arm are respectively provided with a cable clamp, the cable clamp is a cylindrical structure as a whole, which is composed of upper spiral body, middle spiral body and lower spiral body, the joint of the upper spiral body and the middle spiral body is provided with an upper chord cable through hole, and the joint of the middle spiral body and the lower spiral body is provided with a lower chord cable through hole; a plurality of telescopic locking pin shafts are arranged in the upper spiral body and the lower spiral body in the vertical direction, the middle spiral body is provided with locking pin shaft insertion holes corresponding to the locking pin shafts, and the locking pin shafts are inserted and matched with the locking pin shaft insertion holes. The application solves the design problem of the cable net node, reduces the adverse effect of the unbalanced force between the cable nets on the overall structure, increases the force rationality of the node and the safety of the whole cable net, reduces the processing and manufacturing cost and the construction difficulty, and can be applied to the "sky round place" structure of the "Dream of Red Mansions" drama fantasy garden engineering.

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 present application relates to a kind of hanging delivery device and unmanned aerial vehicle, belong to aerospace technology field, solve the reliability and stability of the hanging goods of the hanging delivery device in prior art, the problem of large load required when unlocking, unlocking component occupies large space.The present application includes shell, hook unit, drive unit and connecting unit;Hook unit includes drive arm, connecting rod and hook;Drive arm and hook are hinged to shell by first hinged shaft and second hinged shaft respectively, and the both ends of connecting rod are hinged to drive arm and hook by third hinged shaft and fourth hinged shaft respectively;Hook can rotate around second hinged shaft, to drive connecting rod and drive arm movement;When hook unit locking state, first hinged shaft, third hinged shaft and fourth hinged shaft are collinear.The present application can realize the stability and reliability of the hanging goods when locking state, unlocking only needs small load, unlocking component structure is compact, and occupies small space.
