Description
Technical field
The utility model relates to the force transmission mechanism field of automobile door lock, is specially a kind of arc gear wheel transmission device that is used for arrangements for automotive doors.
Background technology
Automobile door lock is the key equipment of automobile burglar, and and if only and if the key that is complementary of door lock could rotate after inserting lock core, with rear lock core by transmission device drive dead bolt or stretch out or withdraw, thereby make the car door or the locking or unlocking that fall.The transmission mechanism that is connected with lock core at present is generally rectilinear belt and transmits, and sleeve mechanism all to be positioned over the interlayer of car door interior with the saving space.Consider from the angle of more rational aerodynamic arrangement and good looking appearance, automobile car shape is adopted streamlined and smooth transition more and more at present, the also curved panels that adopt of corresponding car door more, present like this linear belt transmission agency commonly used just is difficult to adapt to the arc interlayer of car door, and its range of application just is very limited.Simultaneously, belt transmits and also to exist low precision, loss is big, moment of torsion is little defective.
Summary of the invention
In order to overcome the defective of prior art, provide a kind of compliance strong, transmit the transmission mechanism that is used for the car door door lock that angle is precise and stable, waste is little, torsional forces is big, the utility model discloses a kind of arc gear wheel transmission device that is used for arrangements for automotive doors.
The utility model reaches goal of the invention by following technical solution:
A kind of arc gear wheel transmission device that is used for arrangements for automotive doors, comprise lock core, drive base and drive lid, drive and to be placed on that both form a cavity on the driving base, the front end of lock core has keyhole, the rear end of lock core is inserted to drive base and drive and is covered in the cavity that forms, it is characterized in that: also comprise the taper driving gear, taper travelling gear and taper driven gear, the taper driving gear, taper travelling gear and taper driven gear all place to drive base and drive and cover in the cavity that forms, the taper driving gear be enclosed within lock core the rear end both connect by key, the taper travelling gear is meshed with taper driving gear and taper driven gear respectively.
The described arc gear wheel transmission device that is used for arrangements for automotive doors, it is characterized in that: the quantity of taper travelling gear is 2～6, meshes successively between the taper travelling gear, is positioned at the taper travelling gear at two ends, one and taper driving gear are meshed, and another and taper driven gear are meshed.
The described arc gear wheel transmission device that is used for arrangements for automotive doors is characterized in that: the addendum angle θ of taper driving gear, taper travelling gear and taper driven gear
aAll between 3 °～5 °.
When the utility model uses, taper driving gear, taper travelling gear and taper driven gear are meshed and place the driving base successively and drive and cover in the cavity that forms, the rear end of lock core is connected with the taper driving gear by key, after inserting key and rotary door lock core, transfer a torque to the taper driven gear by taper driving gear and taper travelling gear, and moment of torsion is passed by the taper driven gear.Because the addendum angle θ of taper driving gear, taper travelling gear and taper driven gear
aAll, therefore,, just make that the axis of taper driving gear, taper travelling gear and taper driven gear is all no longer parallel to each other, so just reached the purpose that adapts to the arc car door by the engagement of angular wheels at different levels greater than 0.Change the quantity of taper travelling gear, perhaps change the addendum angle θ of taper driving gear, taper travelling gear and taper driven gear
a, can adapt to the car door of the different radians of different length.The beneficial effects of the utility model are: compliance is strong, and it is precise and stable to transmit angle, and loss is little, and torsional forces is big.

The specific embodiment
Below further specify the utility model by specific embodiment.
Embodiment 1
A kind of arc gear wheel transmission device that is used for arrangements for automotive doors, comprise lock core 1, drive base 2, drive and cover 3, taper driving gear 4, taper travelling gear 5 and taper driven gear 6, as shown in Figure 1, concrete structure is: drive and cover 3 and be placed on that both form a cavity on the driving base 2, the front end of lock core 1 has keyhole, the rear end of lock core 1 is inserted to drive base 2 and drive and is covered in 3 cavitys that form, and taper driving gear 4, taper travelling gear 5 and taper driven gear 6 all place to drive base 2 and drive and cover in 3 cavitys that form.
Taper driving gear 4 as shown in Figures 2 and 3, taper driving gear 4 be enclosed within lock core 1 the rear end both connect by key.
Taper driven gear 6 as shown in Figure 6 and Figure 7.
The addendum angle θ of taper driving gear 4, taper travelling gear 5 and taper driven gear 6
aAll between 3 °～5 °, present embodiment is got 3 °.
When present embodiment uses, taper driving gear 4, taper travelling gear 5 and taper driven gear 6 are meshed and place driving base 2 successively and drive and cover in 3 cavitys that form, the rear end of lock core 1 is connected with taper driving gear 4 by key, after inserting key and rotary door lock core 1, transfer a torque to taper driven gear 6 by taper driving gear 4 and taper travelling gear 5, and moment of torsion is passed by taper driven gear 6.Because the addendum angle θ of taper driving gear 4, taper travelling gear 5 and taper driven gear 6
aAll greater than 0, therefore, engagement by angular wheels at different levels, just make that the axis of taper driving gear 4, taper travelling gear 5 and taper driven gear 6 is all no longer parallel to each other, axis as taper driving gear 4 and taper driven gear 6 forms a θ angle as shown in fig. 1, has so just reached the purpose that adapts to the arc car door.Change the quantity of taper travelling gear 5, perhaps change the addendum angle θ of taper driving gear 4, taper travelling gear 5 and taper driven gear 6
a, can adapt to the car door of the different radians of different length.
