[0021] Compared with the prior art, the advantages and positive effects of the present invention are:

[0022] 1. The utility model is to install the door frame body as a whole at the desired RV, then close the original RV door, then turn on the external power supply of motor 1, use the controller to start motor 1, and the output end of motor 1 starts to drive the main shaft to rotate forward. As the main shaft gradually rotates forward, the wire mesh wrapped on the surface of the main shaft gradually falls from the groove on the surface of the hollow column. As the main shaft continues to rotate forward, the fixed plate on the outer surface of the wire mesh gradually falls to a position near the bottom of the door frame body. Then the staff holds the handle and pulls the handle into the slot. The fixing plate is inserted as a whole between the multiple latches and the door frame body, and the multiple latches are aligned with the multiple sockets. Then the handle is released, and the latch plate and the multiple latches are quickly pushed through the elastic force of the multiple springs, so that the multiple latches quickly pass through the multiple round holes and are inserted into the multiple sockets. In this way, the wire mesh is completely spread out. When the lawbreakers pry open the original door, the staff can use the wire mesh to provide a second layer of protection for the people inside, thereby protecting the people inside the car and preventing the people inside the car from being harmed by some lawbreakers, thereby improving the safety of the people inside the RV.

[0023] 2. In order to deter criminals, the utility model has previously connected the conductive interface to the power supply system in the RV. At the same time, the staff connects the connector of the conductive interface to the surface of the wire mesh. Then the staff uses the controller to start the conductive interface, and the connector of the conductive interface begins to output electricity to the surface of the wire mesh, so that a power grid is formed on the surface of the wire mesh, which strengthens the secondary protection of the RV and creates a certain deterrent to criminals, thereby achieving the goal of deterring criminals when encountering danger and improving the practicality of the RV door frame.

As the main shaft 111 gradually rotates forward, the wire mesh 103 wrapped on the surface of the main shaft 111 gradually falls slowly from the groove on the surface of the hollow column 102. Through the continuous forward rotation of the main shaft 111, the fixed plate 104 on the outer surface of the wire mesh 103 gradually falls to a position near the bottom of the door frame body 1, and then the staff holds the handle 110 and pulls the handle 110 to pull the handle 110 into the sliding groove 107, and then inserts the fixed plate 104 as a whole between the multiple latches 113 and the door frame body 1, and aligns the multiple latches 113 with the multiple sockets 114, and then releases the handle 110, and the elastic force of the multiple springs 108 quickly pushes the plug plate 112 and the multiple The plurality of bolts 113 are quickly inserted into the plurality of holes 105 and the plurality of sockets 114 to spread out the wire mesh 103. When the criminals pry open the original door, the staff can use the wire mesh 103 to provide a second layer of protection for the internal personnel, thereby protecting the personnel in the vehicle and preventing the personnel in the vehicle from being harmed by some criminals, thereby improving the safety of the personnel in the RV. In order to deter the criminals, the conductive interface 2 has been connected to the power supply system in the RV. At the same time, the staff connects the connector of the conductive interface 2 to the surface of the wire mesh 103. Then the staff uses the controller to start the conductive interface 2, and the connector of the conductive interface 2 begins to output electricity to the surface of the wire mesh 103, so that a power grid is formed on the surface of the wire mesh 103, thereby strengthening the secondary protection of the RV and causing a certain deterrent to the criminals, thereby achieving the goal of deterring the criminals when encountering danger and improving the practicality of the RV door frame.
