Detailed Description
The invention will be further described with reference to the following examples.
As shown in fig. 1 and 2, the intelligent lock with an automatic key hole cover of this embodiment includes a lock body 1, a key hole cover 3 is disposed on the lock body 1, a key hole 2, a first piston 4, a second piston 10, a first oil cylinder 5, a second oil cylinder 11, an oil pipe, a magnet 8 and an electromagnet 7 are disposed in the lock body 1, the key hole 2 is disposed at the rear of the key hole cover 3, the key hole cover 3 is connected to the first piston 4, the first piston 4 is disposed below the key hole cover 3, the first piston 4 is disposed in the first oil cylinder 5, the first oil cylinder 5 is connected to the second oil cylinder 11 through the oil pipe, the oil pipe is horizontally disposed, the first oil cylinder 5 and the second oil cylinder 11 are disposed at the same height, the second piston 10 is disposed in the second oil cylinder 11, and the first oil cylinder 5 is connected to the second oil cylinder 11 through the oil pipe, The second oil cylinder 11 and the oil pipe are internally provided with hydraulic oil 6, the second piston 10 is connected with the magnet 8, the magnet 8 is connected above the second piston 10, the electromagnet 7 is arranged above the magnet 8 to generate a magnetic field repulsive to the magnet 8, and the weight of the key hole cover 3 is larger than that of the magnet 8.
when the intelligent lock works normally, a user can open the door lock in a fingerprint identification mode, an ID card identification mode or a password identification mode without using a mechanical key to open the door lock. When the intelligent lock is insufficient in electric quantity, the electromagnet 7 stops being electrified and stops generating repulsive magnetic force to the lower part. At this time, the key hole cover 3 having a weight larger than that of the magnet 8 sinks by gravity, and the first piston 4 connected to the key hole cover 3 is lowered at the position of the first cylinder 5. By the hydraulic action, the second piston 10 is raised at the position of the second cylinder 11, with the magnet 8 connected thereto also being raised. At this time, the key hole cover 3 is opened, and the user can open the intelligent lock through the key hole 2 hidden behind the key hole cover 3.

Meanwhile, the lighter key hole cover 3 is adopted, so that the electromagnet 7 only needs to generate smaller magnetic force to lift the key hole cover 3.
Preferably, the magnet 8 is made of neodymium iron boron, and the material has the characteristics of small volume, light weight and strong magnetism, and is beneficial to adopting a lighter key hole cover 3 and increasing the repulsive force and the effective action range between the electromagnet 7 and the magnet 8.
Preferably, the magnets 8 are bar magnets 8, and the number of the magnets 8 is 2, so that the magnets 8 can generate a larger magnetic force.
preferably, the magnet 8 is surrounded by a magnetic coil 9 to generate a magnetic field repelling the electromagnet 7, so as to increase the repulsion force between the magnet 8 and the electromagnet 7, and the magnet 8 can be magnetized to prevent the magnet 8 from losing its magnetism due to magnetic leakage.
The embodiment avoids the defects that the key hole cover 3 of the intelligent lock in the prior art is inconvenient to open and close and has low automation degree, so that the intelligent lock can automatically open the key hole cover 3 when the electric quantity of the intelligent lock is exhausted, and a user can conveniently open the door lock by means of the mechanical key hole 2; meanwhile, after a new power supply is replaced for the intelligent lock, the key hole cover 3 can be closed again to conceal the key hole 2, and the mechanical key hole 2 is protected and concealed.
