Electronic key with restart function

Abstract

The invention provides an electronic key with a restart function. The electronic key with the restart function comprises a first key bit and a handle, wherein a power source and a working module are arranged in the handle; a first lock cylinder rod is arranged in the first key bit. The electronic key further comprises a second key bit, wherein a slot into which the first key bit is inserted is formed in the second key bit; the first key bit is adaptive to the slot; a fixing structure for fixing the first key bit into the slot in the second key bit is further arranged between the first key bitand the second key bit; a magnetic resetting circuit module used for disconnecting the working module with the power source after approaching a magnet is further arranged in the handle; the magnetic resetting circuit module further comprises a resetting structure for connecting the working module with the power source again after the resetting structure is deviated from the magnet; the magnetic resetting circuit is conducted with the power source through an MOS (Metal Oxide Semiconductor) tube; the first lock cylinder rod is connected with the working module; a second lock cylinder rod connected with the first lock cylinder rod is arranged in the second key bit. By adopting the electronic key provided by the invention, a user can replace the key bit in a more convenient way. Furthermore, the user can conveniently carry more keys at the same time; the electronic key is convenient to restart.

Description

technical field [0001] The invention relates to an electronic key, in particular to an electronic key with restart function. Background technique [0002] Keys include mechanical keys and electronic keys. Electronic keys are one of the tools used to open door locks. They usually include a key head and a handle. The key head is used to match the door lock for unlocking operations, but it is easy to use the key during use. In the case of wear and tear, it is necessary to re-key and replace the handle. Especially for electronic lock keys with remote control devices, it will be more troublesome to replace the key head; Matching, then need to carry a plurality of keys at this moment, take up a lot of space, trouble to use, brought trouble to the user. [0003] And because some manufacturers do not add reset function when making electronic keys, when the electronic key crashes, it can only be restarted by removing the battery after removing the shell, but such an operation will d...

[0002] Keys include mechanical keys and electronic keys. Electronic keys are one of the tools used to open door locks. They usually include a key head and a handle. The key head is used to match the door lock for unlocking operations, but it is easy to use the key during use. In the case of wear and tear, it is necessary to re-key and replace the handle. Especially for electronic lock keys with remote control devices, it will be more troublesome to replace the key head; Matching, at this time, multiple keys need to be carried, which takes up a lot of space and is troublesome to use, which brings troubles to users

[0003] And because some manufacturers do not add reset function when making electronic keys, when the electronic key crashes, it can only be restarted by removing the battery after removing the shell, but such an operation will damage the system, and the electronic keys on the market are It is fixed and installed by screws, so when disassembling the electronic key, it is necessary to remove the screws of the shell first, and then unplug the battery, so that the operation of restarting the electronic key is very cumbersome in practice, and it is very inconvenient for users to operate
