Detailed Description
The magnetic anti-theft lock for the bicycle axle provided by the invention is described in detail below with reference to the specific implementation of the drawings.
A magnetic anti-theft lock for a bicycle wheel axle is characterized in that: the device consists of a transmission mechanism and a control mechanism; the transmission mechanism comprises a hollow shell 9, an inner shaft 1, an electromagnet I6, an electromagnet II 7, a permanent magnet I4, a permanent magnet II 5, a spline 2 and an outer nut 10; the shell 9 comprises a cylindrical cavity, and an electromagnet I6 and an electromagnet II 7 are fixedly connected inside the shell 9; the spline 2 is arranged on the surface of the middle part of the inner shaft 1, and the first internal spline 13 is arranged at the two ends of the inner shaft 1; the permanent magnet I4 and the permanent magnet II 5 are arranged on the inner shaft 1 through the spline 2, and can axially slide along the spline 2 on the inner shaft 1; the inner shaft 1 is connected with the outer shell 9 through a second bearing 19 and a first bearing 8; the outer nut 10 is in threaded connection with the inner shaft 1; the control mechanism comprises a remote controller 20 and a control unit 28, wherein the remote controller 20 is held by a user and comprises a transmitter 21, and the transmitter 21 is a wireless signal transmitting device and is connected with the control unit 28 in a wireless mode; the control unit 28 is arranged inside the shell 9 and comprises a central processing system 24 and a control system 23, and the control unit 28 is connected with the receiver 22, the power supply 12, the loudspeaker 25, the electromagnet I6, the electromagnet II 7, the motion sensor 26 and the GPS positioning module 27 through circuits; the receiver 22 is a wireless signal receiving device; the GPS positioning module 27 is provided with a wireless communication module, which is connected with the mobile phone through a wireless signal.
It is further: a baffle plate 3 is arranged in the middle of the inner shaft 1.
The inside of the outer nut 10 is provided with a second internal spline 16, and the inner wall of the second internal spline 16 on the outer nut 10 is an electromagnet; the inner walls of the first internal spline 13 at the two ends of the inner shaft 1 are permanent magnets; the external spline 14 is assembled in the first internal spline 13 and the second internal spline 16, and can move along the axial direction of the first internal spline and the second internal spline, and the external spline 14 is made of a material which can be attracted by a magnet.
The electromagnet I6 is opposite to the permanent magnet I4 in opposite directions; the electromagnet II 7 is opposite to the permanent magnet II 5 in opposite directions; the first permanent magnet 4 is opposite to the second permanent magnet 5 in opposite directions.
The principle of the magnetic anti-theft lock for the bicycle wheel axle provided by the invention is explained as follows: the user sends a wireless signal to the receiver 22 through the remote controller 20, the receiver 22 transmits the signal to the central processing system 24, the central processing system 24 integrates and calculates the signal and then sends an instruction to the control system 23, the control system 23 controls the electrifying and de-electrifying of the electromagnet I6 and the electromagnet II 7, when the bicycle is in a locking state, the electromagnet I6 fixedly connected to the shell 9 and the electromagnet II 7 are electrified and magnetized, and the magnetic force direction is shown in figure 4, the magnetic force of the electromagnet I6 and the electromagnet II 7 on the permanent magnet 4 and the permanent magnet II 5 is far greater than the magnetic force between the permanent magnet I4 and the permanent magnet II 5, so that the permanent magnet 4 and the permanent magnet II 5 are respectively attracted by the electromagnet I6 and the electromagnet II 7 on the shell 9, at the moment, the electromagnetic clutch is in an engaged state, and the permanent magnet 4 and the permanent magnet II 5 are connected with the inner shaft 1 through the spline 2, the shell 9 cannot rotate circumferentially, and thus the function of locking the bicycle is realized; when a user presses an unlocking button on the remote controller 20, the electromagnet I6 and the electromagnet II 7 are powered off and demagnetized, and the electromagnet I6, the electromagnet II 7, the permanent magnet I4 and the permanent magnet II 5 are separated due to opposite attraction of the permanent magnet I4 and the permanent magnet II 5, so that the unlocking function is realized.
The inner wall of the internal spline 13 at the two ends of the inner shaft 1 contains permanent magnets, in the unlocked state, the external spline 14 is attracted by the permanent magnets in the internal spline 13, and the external spline 14 is not connected with the internal spline 16 in the external nut 10, so that the external nut can rotate in the unlocked state; in the locked state, the electromagnet in the second internal spline 16 of the outer nut 10 is electrified and magnetized so as to attract the external spline 14, and at the moment, the outer nut 10 and the inner shaft 1 are connected through the external spline 14, so that the outer nut cannot rotate, and a thief cannot rotate the outer nut 10 to perform theft.
The anti-theft module consists of an alarm system and a GPS positioning module 27, wherein the alarm system is provided with a motion sensor 26 in the shell 9, and because the bicycle is in a static state under normal conditions, when the bicycle is knocked and carried, the motion sensor 26 collects signals and transmits the signals to the central processing system 24, the central processing system 24 integrates calculation and sends instructions to the control system 23, and the control system 23 controls the loudspeaker 25 to send alarm sounds; the GPS positioning module 27 is disposed inside the housing 9, and is provided with an antenna communication module, and is connected with the mobile phone through a wireless signal, before use, a user sets a range of the bicycle from the user, when the bicycle exceeds the range, the GPS positioning module 27 transmits real-time data information to the mobile phone through wireless communication and sends a piece of coordinate information to the mobile phone of the user, positioning software on the mobile phone of the user receives the coordinate information and invokes a map, such as a german map or other maps of available third parties, to display a position corresponding to the coordinates to realize positioning of the bicycle position, and since the GPS positioning module 27 is disposed at the inner part of the housing 9 and the outer nut 10 cannot be detached, the GPS positioning module 27 cannot be damaged by outsiders.
In summary, the invention effectively improves various defects in the prior art and can effectively solve the problem that the bicycle is stolen, so that the invention can meet the actual requirement and meet the requirements of the invention patent application.
However, the foregoing is merely illustrative of the preferred embodiments of the present invention and is not intended to limit the scope of the invention; therefore, all simple and equivalent changes which come within the meaning and range of equivalency of the claims and specification are intended to be embraced therein.
