Abstract

Disclosed is a remote theftproof lock for an electric bicycle, including a shell body, a brake plate ,a lock head, a lock core, a wireless transmitting remote controller and a wireless receiving controller; a lock hole which can be inserted by the lock head is distributed on the excircle periphery of the brake disk, the lock core is composed of a fixed frame, a front permanent magnet, a rear permanent magnet, a soft magnetic iron core, a coil and a push-pull rod, two extraction terminals of the coil are connected with the controlling output terminal of the wireless receiving controller, the push-pull rod is sequentially passed through a rear end-plate of the fixed frame, the rear permanent magnet, the soft magnetic iron core, the front permanent magnet and a front end-plate of the fixed frame, and is connected with the lock head; the soft magnetic iron core is fixedly connected with the push-pull rod. The magnetic pole direction of the two ends of the soft magnetic iron core can be changed by using the remote controlling to change the current direction of the lock core coil, thereby the sucking state and the rejection state of the front permanent magnet and the rear permanent magnet can be changed to make the soft magnetic iron core produce a front displacement and a rear displacement transiently, the lock head is driven to displace forward and backward, so the lock closing function and the lock opening function can be realized. The structure is simple, the using is convenient, and the reliability is high.

Description

The electric bicycle Remote controlled anti-theft lock

Technical field

The utility model relates to a kind of electric bicycle anti-theft device, particularly a kind of electric bicycle Remote controlled anti-theft lock.

Background technology

Electric bicycle becomes the main walking-replacing tool of people gradually owing to have energy-saving and environmental protection, advantage such as cheap.But meanwhile, the stolen rate of electric bicycle also rises year by year.At present, there is a kind of electric bicycle theftproof lock to be installed in the electric bicycle brake disc housing, the brake disc circumferential periphery is distributed with the lockhole that allows tapered end to insert, its lock core mainly contains two kinds of mechanical lock and automatically controlled lock cores, the former is pure frame for movement, open the lock with the key, the mutual opening rate height, theftproof performance is relatively poor, and must bend over to unblank and shut, inconvenient operation, the latter unblanks by the remote controller drive motors and shuts, and operates more conveniently, but its adopts brush direct current motor to drive tapered end, waterproof, shockproof properties are relatively poor, and theftproof lock is shorter application life.

According to the knowledge of the applicant, existing a kind of relay system electromagnetic lock, its contact energising adhesive (locking-in state), outage flicks (unlocking condition), must could keep locking-in state after outage by complex mechanical construction, therefore existing electromagnetic lock also is not suitable for locking as electric bicycle.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of easy to use, electric bicycle Remote controlled anti-theft lock that reliability is high is provided.

The technical scheme that its technical problem that solves the utility model adopts is as follows: the electric bicycle Remote controlled anti-theft lock, form and comprise housing, brake disc, tapered end, lock core, the wireless transmit remote controller, the wireless receiving controller, the circumferential periphery of described brake disc is distributed with the lockhole that allows tapered end to insert, described brake disc, tapered end, lock core, the wireless receiving controller is positioned at housing, it is characterized in that described lock core is by fixed mount, preceding permanent magnet, back permanent magnet, soft magnet core, coil, pull bar is formed, fixed mount is fixedlyed connected with housing, before permanent magnet and back permanent magnet homopolarity be fixed on opposite to each other fixed mount before, the end plate inboard, soft magnet core is between preceding permanent magnet and back permanent magnet, and keep certain shift length with preceding permanent magnet or back permanent magnet, coil is on soft magnet core, two exits of coil are connected with the control output end of wireless receiving controller, pull bar passes the end plate of fixed mount successively, back permanent magnet, soft magnet core, preceding permanent magnet, the front end-plate of fixed mount, be connected with tapered end, soft magnet core is fixedlyed connected with pull bar.

The utility model can also be realized by following further technical solution: have the tapered end buffer gear of being made up of tapered end seat, spring, draw back plate, tapered end is fixedlyed connected with tapered end seat front portion, spring places in the tapered end seat, draw back plate places tapered end seat posterior medial, and pull bar passes tapered end seat rear portion fixedlys connected with draw back plate.

The beneficial effects of the utility model are as follows: lock core of the present utility model comes down to a kind of electromagnetic type lock core, utilize wireless remote control to change the sense of current of lock core coil, just can change the pole orientation at soft magnet core two ends, thereby change the adhesive or the repulsion state of soft magnet core and forward and backward permanent magnet, make soft magnet core moment produce forward and backward displacement, drive pull bar and the forward and backward displacement of tapered end, realize locking and the function of unblanking.Because soft magnet core no longer has magnetic behind coil losing electricity, so lock core can keep the state after the straighforward operation.Utilize additional tapered end buffer gear, can effectively insert the lockhole that is arranged in the brake disc periphery after brake disc makes the tapered end locking, improve the reliability of theftproof lock by finely tuning.Therefore this Remote controlled anti-theft lock is simple in structure, easy to use, the reliability height.
