Abstract

The utility model belongs to the technical field of anti-theft locks, and especially discloses an anti-theft lock for brushless motor electric bicycles. The anti-theft lock comprises a lock shell and a rotary lock cylinder, wherein a back end of the lock cylinder is provided with two or three plugs electrically connected together, a back end of the lock shell is provided with two or three terminals, back ends of the terminals are connected with wires respectively, and front ends of the terminals are provided with bearing sheets matched with the plugs. When the lock cylinder is in a locking state, the plugs contact with the bearing sheets, and the plugs are separated from the bearing sheets, otherwise. When the anti-theft lock is used, the wires are connected with arbitrarily two or three of the three phase lines coming out from a controller. Therefore, when the lock cylinder is in a locking state, two or three phase lines are contacted through plugs and bearing sheets, and thus a brushless motor cannot work even when being powered on. Due to effects of a highfield and coils, a theft can not easily push or ride an electric bicycle locked by the anti-theft lock. Moreover, the structure of the electric bicycle does not need to be changed, thus making the anti-theft lock convenient to popularize.

Description

The brushless motor Electrical Bicycle is used anti-theft column lock

Technical field

The utility model belongs to the anti-theft column lock technical field, and particularly a kind of brushless motor Electrical Bicycle is used anti-theft column lock.

Background technology

At present the brushless motor Electrical Bicycle is extensively promoted with its energy-saving and environmental protection, advantage such as light, but the anti-theft measure of this kind Electrical Bicycle is relatively poor, and Electrical Bicycle is with respect to bicycle, and prices are rather stiff, is easy to stolen by the lawless person.Electrical Bicycle adopts mechanical lock and power supply lock mostly at present; Mechanical lock is easy to destroyed; In fact just adopt the antitheft of power supply lock; Even but present Electrical Bicycle power supply is locked under the situation of locking, modes such as thief can adopt and ride, implementation are stolen Electrical Bicycle, have very heavy losses for the Electrical Bicycle user.

The utility model content

The technical matters that the utility model solves just provides a kind of good anti-theft effect, the very difficult brushless motor Electrical Bicycle of carrying out or riding is used anti-theft column lock under locking states.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:

The lock core that comprises lock shell and rotation; Be provided with two or three plugs of mutual electrical connection in described lock core rearward end, be provided with adapter plate, on said adapter plate, be fixed with two or three binding posts at said housing front end; The rear end of said binding post is connected with lead respectively; Be provided with the sheet of accepting with said plug coupling at said binding post front end, when said lock core was in locking states, said plug contacted with the said sheet of accepting; When said lock core was in opening, said plug separated with the said sheet of accepting.

The brushless motor Electrical Bicycle that the utility model provided is compared with prior art with anti-theft column lock and is had the following advantages: owing to comprise the lock core of lock shell and rotation; Be provided with two or three plugs of mutual electrical connection in described lock core rearward end, be provided with adapter plate, on said adapter plate, be fixed with two or three binding posts in said housing rear end; The rear end of said binding post is connected with lead respectively; Be provided with the sheet of accepting with said plug coupling at said binding post front end, when said lock core was in locking states, said plug contacted with the said sheet of accepting; When said lock core is in opening; Said plug separates with the said sheet of accepting, and during use, two leads is connected on wherein any two of three phase lines that slave controller comes out to brushless motor; If lead is three, just be connected respectively on three phase lines; When lock core is in locking states, two or three phase lines through plug with accept sheet and contact, can not work under the situation of brushless motor power connection even make; And three or two phase lines link together; Because the effect of highfield and coil makes brushless motor rotate difficulty, thief is after opening mechanical lock; Be difficult to carry out or the Electrical Bicycle of riding; Play anti-theft effect preferably, and do not change the structure of present Electrical Bicycle, be convenient to promote.

Description of drawings

Fig. 1 is brushless motor Electrical Bicycle that the utility model the provided structural representation with the anti-theft column lock opening;

Fig. 2 is brushless motor Electrical Bicycle that the utility model the provided structural representation with the anti-theft column lock locking states;

Fig. 3 is the structural representation that has plug one end lock core;

Fig. 4 is the structural representation of adapter plate.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the brushless motor Electrical Bicycle that the utility model provided is done further detailed description with the structure of anti-theft column lock.

Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, this brushless motor Electrical Bicycle comprises lock shell 1 and the lock core 2 that rotates with anti-theft column lock, is provided with three plugs 3 in lock core 2 rearward end; Certainly, plug 3 can be two, and each plug 3 is electrically connected through electric connection line 4 each other; Be provided with adapter plate 8 in the rear end of housing 1; On adapter plate 8, be fixed with three binding posts 5, certainly, binding post 5 can be two; The rear end of binding post 5 is connected with lead 6 respectively, binding post 5 front ends be provided with plug 3 coupling accept sheet 7.When lock core 2 was in locking states, plug 3 contacted with accepting sheet 7, when lock core 2 is in opening, plug 3 with accept sheet 7 and separate.

During use, can this lock shell 1 be fixed on the on the face preceding of car, three leads 3 are connected respectively on three phase lines that slave controller comes out to brushless motor,, two leads 3 are connected on wherein any two of three phase lines if lead 3 is two.Like this, when lock core 2 is in locking states, two or three phase lines through plug 3 with accept sheet 7 and contact, can not work under the situation of brushless motor power connection even make; And three or two phase lines link together; Because the effect of highfield and coil makes brushless motor rotate difficulty, thief is after opening mechanical lock; Be difficult to carry out or the Electrical Bicycle of riding; Play anti-theft effect preferably, and do not change the structure of present Electrical Bicycle, be convenient to promote.

Certainly, also can be provided with in the lock core rearward end and accept sheet, binding post is provided with plug.

The foregoing description is the explanation to the utility model; Therefore; The protection domain of the utility model not only is confined to the foregoing description, as long as structure is identical with anti-theft column lock with the utility model brushless motor Electrical Bicycle, just drops on the scope of the utility model protection.

Claims

1. the brushless motor Electrical Bicycle is used anti-theft column lock, comprises the lock core of lock shell and rotation, it is characterized in that: two or three plugs being provided with mutual electrical connection in described lock core rearward end; Be provided with adapter plate in said housing rear end; On said adapter plate, be fixed with two or three binding posts, the rear end of said binding post is connected with lead respectively, is provided with the sheet of accepting with said plug coupling at said binding post front end; When said lock core is in locking states; Said plug contacts with the said sheet of accepting, and when said lock core was in opening, said plug separated with the said sheet of accepting.
