Description
Technical field
A kind of lockset is the utility model is related to, more particularly to a kind of automatically controlled bicycle lock.
Background technology
With the rise of shared bicycle, the use of automatically controlled bicycle lock is more and more extensive.
1st, existing automatically controlled bicycle lock：When shutting, mobile locking bar, stretched with hour locking lever extension spring, close fore shaft, work as locking bar
On notch alignment latch when, latch inserts locking bar breach and locking under latch spring thrust；During unlocking, motor turns
It is dynamic to drive eccentric shaft（Cam）, overcome latch spring thrust that latch is exited from the breach of circular arc locking bar, locking bar is drawn in locking bar
Retracted in the presence of spring, fore shaft opens.
2nd, the defects of present automatically controlled bicycle lock：
After shutting, latch inserts the breach of locking bar in the presence of latch spring, to stop the movement of locking bar, closes lock
Mouthful.Latch is only withstood by the strength of latch spring, and coupling mechanism force is very weak.When by strong impaction or vibration, especially from slotting
When selling the strong impaction of glide direction, external force is transmitted to latch, compresses latch spring, exits locking bar breach, in the moment exited,
Locking bar is removed in the presence of locking bar extension spring, fore shaft automatic opening, is caused lock to fail, is discharged by lock object.
If very big torsion is needed to overcome latch spring thrust, meeting using the big latch spring of strength, when motor is unlocked
Lead to not unlock.Also can not thoroughly solve the problems, such as that lock is unlocked by external force simultaneously, as long as external force is powerful enough, a total energy lock is beaten
Open, cause lock to fail, discharge by lock object.
The content of the invention
The purpose of this utility model is to provide a kind of reliable, reasonable in design, reliable automatically controlled bicycle lock that locks.
To achieve the above object, technical solution of the present utility model is：
The utility model is a kind of automatically controlled bicycle lock, including lock housing, locking bar, locking bar extension spring, button, motor, drive shaft,
Spacing briquetting, latch, latch spring, the first travel switch, the second travel switch；Described locking bar activity is nested with the lock in lock housing
In bar groove, locking bar extension spring is nested with lock housing and the both ends of locking bar extension spring are separately fixed at one end of locking bar and the inwall lock of lock housing
On bar groove one end, button is fixedly arranged in the middle of in locking bar, the button passes lock housing；Described latch activity be nested with lock housing and
The inner of latch penetrate the locking bar groove of lock housing and holding on the inner neck of locking bar, latch spring is arranged in lock housing and latch
The both ends of spring are acted against on the outer end and lock-shell lining of latch respectively, and motor is arranged in lock housing, the output shaft of motor and drive
The outer end connection of moving axis, the inner face of drive shaft are provided with eccentric shaft or cam, and the eccentric shaft or cam are slipped in the middle part of latch
Driver slot in, driving latch moves back and forth, and the matching relationship of holding or disengaging is formed with the neck on locking bar the inner；Described
Spacing briquetting is wrapped on one side of something of drive shaft, forms projection, and the first travel switch is arranged in lock housing and positioned at drive shaft
Side, the first travel switch can be with the spacing briquettings in drive shaft against the second travel switch is arranged in lock housing and the second row
Cheng Kaiguan can with the pressing plate on latch outer end against.
The utility model also includes control module；The control module is arranged in lock housing and opened by wire and the first stroke
Pass, the electrical connection of the second travel switch, motor.
One side of described bolt driving groove is straight flange, another side is circular arc side.
The both sides of described bolt driving groove are all straight flange.
One side of described bolt driving groove is straight flange, another side is convex outer curve, and the radius of curvature of convex outer curve is more than
The radius of gyration of eccentric shaft.
The combination side that one side of described bolt driving groove is straight flange, another side is straight flange and circular arc or curve, combine side
The radius of curvature of middle circular arc or curved section is more than the radius of gyration of eccentric shaft or cam.
After such scheme, the utility model has advantages below：
1st, because the utility model adds the retaining mechanism being mainly made up of motor, drive shaft, latch etc., shutting
Afterwards, motor is rotated again, and the eccentric shaft on the inner face of drive shaft or cam peak are transferred in the driver slot of latch, blocked
Latch exits locking bar breach, realizes the locking of lock.
2nd, because the utility model does not increase part, the driving groove shape and eccentric shaft on latch are passed through（Cam）Fortune
It is dynamic to coordinate, make eccentric shaft（Cam）Unlock and lock by the driver slot on latch, it is reasonable in design, simple.
3rd, the utility model, to start or stop the operating of motor, controls the interior of drive shaft by the state of travel switch
Eccentric shaft or cam peak stop place on end face, controlled than circuit more reliable.
4th, the utility model thoroughly solves the phenomenon that lock is easily opened by force by external force, and current lock is locked by spring force
Tightly, and spring by the easy deformation of external force, lock is easily strongly opened.Increase retaining mechanism, avoid lock from strongly being opened.
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.

As shown in Fig. 8-Figure 13, when shutting, button 4 of leaving behind manually, locking bar extension spring 3 stretches, and locking bar 2 moves along chute, when
When the neck 21 of locking bar 2 is moved to latch 8, latch 8 inserts the neck 21 of locking bar 2 in the presence of latch spring 9, stops locking bar
2 movement, close fore shaft, now, the driver slot 81 on latch 8 also be moved into drive shaft 6 eccentric shaft 61 or cam 61 ' just
The position that can be transferred to, while latch 8 pushes down the second travel switch 20, motor 5 rotates immediately, eccentric shaft 61 in drive shaft 6 or
Cam 61 ' is transferred in the driver slot 81 of latch 8.When the spacing briquetting 7 in drive shaft 6 leaves the first travel switch 10, motor 5 stops
Rotation stop is moved, and now the eccentric shaft 61 in drive shaft 6 or the peak of cam 61 ' are rested in the driver slot 81 of latch 8, and are driven
The circular arc side 812 of eccentric shaft 61 or the peak of cam 61 ' and the driver slot 81 of latch 8 on axle 6（As shown in figure 16）, straight flange
812A（As shown in figure 17）, curved side 812B（As shown in figure 18）, the combination side 812C of straight line and curve（As shown in figure 19）Between
Gap is less than the stroke that latch 8 exits the neck 21 of locking bar 2.
Emphasis of the present utility model is that：Provided with retaining mechanism.
It is described above, only the utility model preferred embodiment, therefore the utility model implementation can not be limited with this
Scope, i.e., the equivalent changes and modifications made according to present utility model application the scope of the claims and description, it all should still belong to this reality
In the range of being covered with new patent.
