Abstract
The utility model discloses an electromagnetic lock which comprises a lock shell. The lock shell is internally provided with a main electromagnet device and an auxiliary electromagnet device that are arranged vertically to each other; the main electromagnet device comprises an electromagnetic coil main body and an iron core; one end of the iron core is provided with a locking pillar that extends out of the lock shell; a spring is arranged between the locking pillar and the electromagnetic coil main body; a first check block is arranged at the transition position between the iron core and the locking pillar; the auxiliary electromagnet device comprises an auxiliary electromagnet coil main body and an auxiliary iron core; the end part of the auxiliary iron core corresponds to the clearance position between the extending stroke and the shrinking stroke of the first check block; and the auxiliary iron core is sheathed with a return spring. By adopting the structure of the electromagnetic lock, the lock shell can be arranged inside a frame of an electric bicycle, so that the frame can be locked safely and reliably by the flexibility of the locking pillar; and when the frame is locked, the electromagnetic lock is positioned in the frame, and lawbreakers are difficult to open the frame by violence, so that the theft-protection performance of the electric bicycle is improved.
Description
Technical field
The utility model relates to a kind of electromagnetic lock.
Background technology
Electrical Bicycle obtains use more and more widely in daily life owing to use environmental protection, convenience.At present, because theft-proof needs, people can add anti-theft column lock to Electrical Bicycle usually.The volume of this anti-theft column lock is bigger, generally is locked on the wheel of Electrical Bicycle, allows the lawless person that chance by tool to open is arranged, and safety can not get ensureing.Electrical Bicycle is propped up car with vehicle frame in the time of withdraw from service usually, makes its rear wheels liftoff.If lock is installed with its holding state locking on vehicle frame, is improved the difficulty of lawless person's stealing.Traditional electric control head lock adopts a secondary electromagnet apparatus to control, its structure comprises electromagnetic coil body and iron core, the front end sleeve of iron core is provided with retracing spring, this front end also is provided with lock, how electromagnetic lock is applied on the vehicle frame of Electrical Bicycle, realization is to the locking of vehicle frame, and the crime difficulty that improves the lawless person is the technical matters that needs to be resolved hurrily.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of electromagnetic lock that realization locks vehicle frame on the cycle frame that can be applicable to.
In order to solve the problems of the technologies described above, a kind of electromagnetic lock of the present utility model, comprise lock housing, be provided with the main electromagnet device and the secondary electromagnet apparatus of two orthogonal installations in the described lock housing, the main electromagnet device comprises electromagnetic coil body and iron core, one end of iron core is provided with lock, lock stretches out outside the lock housing, be provided with spring between lock and the electromagnetic coil body, iron core and lock transition position are provided with first block, secondary electromagnet apparatus comprises secondary electromagnetic coil body and secondary iron core, and stretch corresponding to first block end of secondary iron core, contract interstitial site between the stroke, secondary iron core sleeve is provided with retracing spring.
As improvement of the technical scheme, described secondary iron core is provided with second block, and described retracing spring is arranged between second block and the secondary electromagnetic coil body.
The beneficial effects of the utility model are: this electromagnetic lock can be installed to the lock housing of electromagnetic lock the vehicle frame inside of Electrical Bicycle owing to adopt said structure, and is by the stretching vehicle frame is locked of lock, safe and reliable; When vehicle frame locked, because electromagnetic lock is positioned at vehicle frame inside, the lawless person was difficult to use force and opens it, and has improved the theftproof performance of Electrical Bicycle.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a unlocking condition scheme drawing of the present utility model;
Fig. 2 is a lock-out state scheme drawing of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of electromagnetic lock of the present utility model, comprise lock housing 1, be provided with the main electromagnet device and the secondary electromagnet apparatus of two orthogonal installations in the described lock housing 1, the main electromagnet device comprises electromagnetic coil body 21 and iron core 22, one end of iron core 22 is provided with lock 23, lock 23 stretches out outside the lock housing 1, be provided with spring 24 between lock 23 and the electromagnetic coil body 21, iron core 22 is provided with first block 25 with lock 23 transition positions, secondary electromagnet apparatus comprises secondary electromagnetic coil body 31 and secondary iron core 32, and stretch corresponding to first block 25 end of secondary iron core 32, contract interstitial site between the stroke, secondary iron core 32 is arranged with retracing spring 33.This electromagnetic lock can be installed to the lock housing of electromagnetic lock the vehicle frame inside of Electrical Bicycle owing to adopt said structure, and is by the stretching vehicle frame is locked of lock, safe and reliable; When vehicle frame locked, because electromagnetic lock is positioned at vehicle frame inside, the lawless person was difficult to use force and opens it, and has improved the theftproof performance of Electrical Bicycle.
In the present embodiment, for the better movement position that limits secondary iron core 32, secondary iron core 32 is provided with second block 34, and described retracing spring 33 is arranged between second block 34 and the secondary electromagnetic coil body 31.In work, turn to when shutting in open mode, give secondary electromagnetic coil body 31 power supplies earlier, secondary iron core 32 is sucked by secondary electromagnetic coil body 31, lock ejects under spring 24 effects, secondary electromagnetic coil body 31 outages, secondary iron core 32 resets under action of reset spring and is stuck in first block, 25 rear sides, promptly shuts; Being locked in closed condition turns to when unblanking, give secondary electromagnetic coil body 31 power supplies earlier, secondary iron core 32 is sucked by secondary electromagnetic coil body 31, before secondary electromagnetic coil body 31 is not cut off the power supply, gives electromagnetic coil body 21 power supplies again, lock is sucked by electromagnetic coil body 21, the outage earlier of secondary electromagnetic coil body 31, secondary iron core 32 ejects under action of reset spring, is stuck in first block, 25 front sides, electromagnetic coil body 21 back outages promptly shut.
The above only is a preferential embodiment of the present utility model, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection domain of the present utility model.
