The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, be respectively the structural representation of first embodiment of the present utility model, wherein, Fig. 1, Fig. 3, Fig. 5 are all corresponding to lock car state, and Fig. 2, Fig. 4, Fig. 6 have figure as can be known all corresponding to unlocking condition, and the utility model comprises:
A support body 1 is fixed on a side of bicycle rear 9; In the present embodiment, offer a perforation 11 on this support body 1, for an end of the wheel shaft 91 that is set in bicycle rear 9, a side of this support body 1 also is provided with a pair of armful of ear 12, is used for being stuck on the bicycle rear fork frame 92, rotates to prevent support body 1;
A heel brace 2 is articulated on this support body 1 by a transverse axis 21;
A lock pin 4 is fixed on the opposite side of this bicycle rear 9; In the present embodiment, these lock pin 4 one ends are provided with axis hole 41, are set on the other end of the wheel shaft 91 of bicycle rear 9 earlier with this axis hole 41, then this lock pin 4 are captiveed joint with this bicycle rear fork frame 92;
One pinion driving system 5 is connected between this transverse axis 21 and the longitudinal axis 31, interlock this heel brace 2 and this lock 3.
See also as Fig. 5, shown in Figure 6, this gear train assembly 5 comprises again:
A driving bevel gear 51 is arranged on this transverse axis 21, rotates synchronously with this heel brace 2;
A passive bevel gear 52 is connected with a joggle with this driving bevel gear 51;
An active straight gear 53 is with these passive 52 coaxial connections and rotation synchronously of bevel gear;
A passive straight gear 55 is arranged on this longitudinal axis 31, and direct or indirect and this active straight gear 53 is connected with a joggle, and these passive straight gear 55 these locks 3 of drive rotate synchronously.
In the present embodiment, pass through middle straight gear 54 engaged transmission between this active straight gear 53 and this passive straight gear 55, thus, under the less prerequisite of the diameter that guarantees straight gear 53,54,55, can between this active straight gear 53 and this passive straight gear 55, reserve enough big distance, make lock 3 can avoid the interference of the sprocket wheel on the trailing wheel 9.And in fact, directly mesh this passive straight gear 55 with active straight gear 53, perhaps, between this active straight gear 53 and this passive straight gear 55, plural middle straight gear is set and comes engaged transmission, also be feasible, just need adjust the diameter of gear.
From Fig. 3, Fig. 4 as can be known, when heel brace 2 falls, the rotation of heel brace 2 will drive driving bevel gear 51, passive bevel gear 52 successively, initiatively straight gear 53, middle straight gear 54 and passive straight gear 55 rotate, the final lock 3 that drives rotates to wheel shaft 91 directions that are parallel to trailing wheel 9, and it is sealed with this lock pin 4, therefore, parking is once finished with the action of lock car, and is very convenient.And when picking up the car, earlier lock 3 is opened, pull heel brace 2 then to level attitude, can drive lock 3 and rotate to wheel shaft 91 directions perpendicular to trailing wheel 9, unblank and the action of packing up heel brace 2 also is to finish in a step, convenient and swift equally.And, use the utility model, when stopping, can finish the lock car, can not forget the situation of lock car, reduced the stolen risk of bicycle.
In order to prevent that heel brace 2 by gravity accidents from falling, cause lock 3 to insert in the trailing wheel 9 and cause danger, also should between heel brace 2 and support body 1, tensioning spring 13 be set, this tensioning spring 13 is often used on the heel brace of ordinary bicycle, does not repeat them here.
And in the process of lock car, might be because the lockpin hole of lock 3 can not align fully with lock pin 4, the convenience that influence is used.For this reason, can further adjust the structure of lock pin 4, shown in Fig. 2 A, be provided with a flap 45, a flanging of this flap 45 be set on the wheel shaft 91 of bicycle rear 9 by centre hole 451 and spiral shell solid, another flanging of this flap 45 can be solid for an end spiral shell of lock pin 4; " door " font locating plate with exit skirt 461 46 is fixing with this flap 45 welding, and this exit skirt 461 can be directed to correct position with lock 3 in lock car process, thus with the corresponding engaging of the other end of lock pin 4.In order to make the engaging process more smooth, preferably the lockpin hole of lock 3 also is set as the shape of outside flaring.
Fig. 7, shown in Figure 8 for another example, be respectively the inner structure scheme drawing of another embodiment of the present utility model under lock car state and unlocking condition, it comes down to the position of bevel gear transmission in the gear train assembly and straight gear transmission is changed, and the gear train assembly 5 after the transposing comprises:
An active straight gear 56 is arranged on this transverse axis 21, rotates synchronously with this heel brace 2;
A passive straight gear 57, direct or indirect and this active straight gear 56 is connected with a joggle;
A driving bevel gear 58 is with these passive 57 coaxial connections and rotation synchronously of straight gear
A passive bevel gear 59 is arranged on this longitudinal axis 31, be connected with a joggle with this driving bevel gear 58, and these passive bevel gear 59 these locks 3 of drive rotates synchronously.
In the present embodiment, pass through middle straight gear 561 engaged transmission between this active straight gear 56 and this passive straight gear 57; This passive bevel gear 59 drives locks 3 rotations by the rotating disk 591 of setting coaxial with it and rotation synchronously.
It should be noted that principal feature of the present utility model is, utilize gear train assembly 5, make to form interlock between heel brace 2 and the lock 3, simplify lock range of driving preface, prevent to forget the lock car.Other structure all has a lot of replacement forms, for example:
The concrete pattern of support body should be the structure of mate gear driving system and selecting;
Lock pin is fixed on the structure of another side of trailing wheel, also can be to be fastened on the axletree with nut;
This passive straight gear 55 drives the structure that this lock 3 rotates synchronously, can be that this lock 3 is weldingly fixed on the flank of tooth of this passive straight gear 55, also welding gasket on the flank of tooth of passive straight gear 55 earlier is weldingly fixed on this lock 3 on this pad then.
In addition, what deserves to be explained is, in the above-described embodiments, lock after sealed is positioned at the rear of the wheel shaft of trailing wheel, and in fact, lock after sealed also can be positioned at the place ahead, top or the below of the wheel shaft of trailing wheel, only otherwise interfere with sprocket wheel, chain, rear crotch and back seat support etc., even installation site of the present utility model can be done freely to adjust in 360 degree scopes, and the technical scheme of installation site after adjusting, all be those skilled in the art on basis of the present utility model, do simple change just available.
More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.
