Description

Safety type caravan lock Technical Field The utility model relates to the field of caravan locks, in particular to a safe caravan lock. Background The motor home is used as a mobile carrier integrating accommodation and traffic functions, and the safety of the motor home is the core of attention of users. The door lock is used as a first barrier for car as a house safety protection, needs to meet the anti-theft and anti-damage requirements under the outdoor complex environment, and simultaneously ensures convenient operation under emergency conditions, so that the requirements on the structural reliability and the safety protection level of the lock are quite high. The existing car as a house locks on the market are mainly divided into two main types, namely mechanical locks and electronic locks. The electronic lock is added with an electronic control module, is commonly provided with a coded lock, a brushing card and the like, and triggers an electromagnetic mechanism to drive the lock tongue to move by inputting a correct code or sensing the card, and part of the electronic lock also integrates a remote control function. In the prior art, the single locking structure has the defects that the lock is only dependent on a lockset of a mechanical rotation lock, a lock core is easily damaged by violence of a tool or the lock is unlocked by a technical means, a simple electronic coded lock directly loses a locking function if a circuit is failed or maliciously powered off, an electronic element has poor stability in an outdoor humid and high-temperature environment, is easy to trigger or malfunction by mistake, and cannot form double safety guarantee.
