Abstract
The utility model discloses a lock for electric bicycles, which is composed of a lock body, a lock core, lock pins, and a drive mechanism, wherein, the drive mechanism is in a structure of gears and racks. The lock core drives the gears to rotate, and the gears drive the racks so that the lock pins can be respectively inserted into a lock hole of a battery box and a lock hole of a front handlebar; therefore, the utility model realized the function that one lock can respectively lock the battery box and the front handlebar, and the inconvenience for users to install a plurality of locks is reduced. The utility model has the advantages of simple structure and easy manufacture, and therefore, the utility model is an ideal fitting for electric bicycles.
Description
The utility model relates to a kind of electric bicycle lock, belongs to lock technology field.
The special lockset of electric bicycle is the indispensable accessory of electric bicycle, the battery case of electric bicycle need often take off charging, but is the demolition parts, need fix and lock again after being installed on the car body, in order to avoid movable with lose the special lockset of battery case so electric bicycle all needs to lock.In addition, locking device, after the locking, preceding handle just can not rotate, and rides to prevent that other people from stealing before all having in the design of a lot of electric bicycles.Add the general trailing wheel commonly used or the lockset of other type, such electric bicycle just needs multiple lockset, makes troubles to the user.How to reduce the trouble that the user opens multiple lockset, the function that can finish these locksets simultaneously again is the problem that the technician should solve.
The purpose of this utility model provides a kind of special electric bicycle lock of can lock simultaneously battery case and the preceding handle of locking.
The purpose of this utility model is achieved in that
A kind of electric bicycle lock, it comprises lock body, lock core, its special feature is, it have two lock pins respectively with battery case lockhole and preceding corresponding lockhole, between lock core and two lock pins, transmission mechanism is arranged.
Above-mentioned electric bicycle lock, described transmission mechanism comprises travelling gear and two tooth bars, one end of described travelling gear links to each other with lock core, tooth bar places the relative both sides of travelling gear respectively, on each tooth bar near travelling gear an end tooth is arranged, and be meshed with travelling gear, the other end is a lock pin.
Above-mentioned electric bicycle lock, described travelling gear is the elongated cylindrical gear.
Above-mentioned electric bicycle lock, described tooth bar is cylindrical rack or plate shaped tooth bar.
Adopt the electric bicycle lock of said structure, can stir the tooth bar of travelling gear both sides respectively when lock core rotates, promptly realized locking, reduced the inconvenience that the user need multiple lockset battery case and preceding with a lock.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
As can be seen from the figure, the utility model is by lock body 1, lock core 2, transmission mechanism, compositions such as lock pin.What transmission mechanism showed in the drawings is gear-rack structure.Travelling gear 7 is the elongated cylindrical gear, and its end is connected with lock core 2.On travelling gear 7, following both sides respectively have a tooth bar 8,9 respectively, tooth bar 8,9 is meshed with travelling gear, described tooth bar is cylindrical rack or plate shaped tooth bar, the modulus of its tooth is identical with module, the advantage of cylindrical rack is need not to adjust direction when mounted, and the latter's advantage is a handling ease.The other end of tooth bar is a lock pin, they respectively with the lockhole of battery case 5 and preceding corresponding the lockhole on 6.
During use, the driver inserts lock core with key, rotates 90 degree, and the lock pin facing to the battery case lockhole is inserted in the lockhole, and battery case is fixed.As handle before the need locking, then be rotated further 90 degree, before inserting, in the lockhole of handle, preceding handle is fixed by the lock pin of lock core drive opposite side, and this moment, the battery case lock pin moved forward, and there is no other influences.For reaching above-mentioned purpose, should there be difference the position of the lock pin of travelling gear both sides when lockset is opened.Be to design so specifically: in the present embodiment, the external diameter of gear is 20 millimeters, rotate 90 degree, then the tooth bar of gear driven both sides moves 16 millimeters, when lock core forwards to two-way when being the enable possition, the battery case lock pin should be in its jack forward position, rotational lock core just can drive tooth bar makes lock pin insert jack, and precedingly when being the full open position, lock core should be a bit larger tham 16 millimeters to lock pin with the jack spacing, when lock core rotates 90 degree self-contained battery boxes, preceding lock pin is moved 16 millimeters under rack drives, arrive the jack forward position, as handle before the need locking, then rotational lock core could insert lock pin preceding jack again.Driver such as need locking battery case then inserts key turns 90 degree self-contained battery boxes like this, as getting final product then being rotated further 90 degree again before the need locking.
Except said gear one rack gear of present embodiment; also can adopt eccentric cam drive mechanism or shift fork drive mechanism; these two kinds of kinds of drive all have application on a lot of unidirectional locksets, and adopt two-way control respectively battery case and preceding the locking also should belong to protection domain of the present utility model.
In the utility model, in the locking battery case, also can realize locking to battery case lid 10, its structure is that a lock hook is installed on lock body 1, its lower end is fixed on the lock body, and lock hook can rotate around fixed axis, and strain with spring the upper end, when lock core rotates, this lock hook can travel forward under the extension spring effect with tooth bar 8, and the lock hook front end just can collude the snap ring that battery case lid 10 stretches out tightly, and battery case is fixed.When the user will open battery case and battery case lid, the backward rotation lock core, tooth bar 8 runs back, and when lock pin withdrawed from jack, tooth bar also pushed up lock hook backward, and the front end of lock hook and the snap ring of battery case lid are thrown off.The utility model not only can lock battery case and preceding handle like this, also can lock battery case lid.
