Abstract
The utility model discloses a trunk lock for a sedan car, which comprises a lock body, an electric actuator, a pawl and a claw. The electric actuator mounted on the lock body is connected with the claw; the pawl and the claw are pivoted at the position of a closing opening of the lock body; and the electric actuator includes a motor, a worm, a worm gear and a swing arm, wherein the motor is fixed onto the lock body, the worm is connected with a motor shaft, the worm gear is meshed with the worm, and the herringbone swing arm is connected with the worm gear. The upper end of the swing arm is provided with a swing arm shaft hole and pivoted on the lock body; the lower end of the swing arm is respectively provided with a pulling end and an opening end; and the swing arm is connected with the claw in a contacting manner by the aid of the opening end.

Description
Technical field
The utility model relates to a kind of vehicle lock, particularly relates to a kind of three-box car baggage compartment lock, and it has independently automatically controlled actuator and pure mechanical lock structure.
Background technology
In the vehicle in early days, automobile trunk lock adopts the pure machinery of the stone dead wire pulling mode of unblanking usually, opens boot at every turn, and the driver must get off, with key manual unlocking boot, very trouble.
Notification number is that the Chinese utility model patent of CN2380642Y discloses the automatically controlled unlocking apparatus of a kind of automobile luggage boot, comprise micromotor, driving gear, roller, reduction gearing, driven wheel, sheave and stone dead wire and housing, be characterized in that driving gear is fixed on the motor shaft, roller and driving gear interlock; Housing bottom is injected with sheave steel axle, and sheave and driven wheel are contained on the sheave steel axle, driven wheel and reduction gearing interlock, and stone dead wire is on sheave, and stone dead wire one end is connected with dead bolt.When unblanking, connect power supply, motor rotates, and driving gear drives roller, reduction gearing, driven wheel, sheave rotation, and along with sheave rotates, stone dead wire twines backward, and the pulling dead bolt is opened the automobile luggage boot.This technical scheme is actually with external YE and replaces manual pulling steel wire to open back-up case lock, though can solve the driver must get off and open the problem of boot, but external YE sealing difference easily enters dust, causes actuator clamping stagnation, disabler.
Notification number is that the Chinese utility model patent of CN200952289Y discloses a kind of car trunk lock, this baggage compartment lock comprises shell, is positioned at the dead bolt and the revoliving arm of shell, also comprise motor and transmission mechanism in the enclosure, described transmission mechanism is connected between motor and the revoliving arm.By this baggage compartment lock, the driver can utilize key to open luggage-boot lid by traditional mode, also can open luggage-boot lid by the control signal drive motors in driver's cabin and does not need to get off.But the transmission mechanism of this technical scheme and lockable mechanism too complexity and overall volume are bigger.
Publication number is that the Chinese utility application of CN201460518U discloses a kind of automatically controlled baggage compartment lock, comprises YE and mechanical lock body, also comprises: the integrated power transmission shaft that has motion thread; The machinery lock body comprises: separate lock construction element, rotate in dead bolt between enable possition and the fastening position, ratchet, with returning spring and the worm gear of dead bolt top to the enable possition; One end of dead bolt and ratchet engagement, the other end is provided with conducting strip; Worm gear respectively with the motion thread of integrated power transmission shaft and ratchet engagement; YE comprises: one drives the power circuit of integrated power transmission shaft and the signal output apparatus of being made up of two leads, when dead bolt in the enable possition or during fastening position, two leads of conducting strip Continuity signal output circuit.This utility model can directly define the feedback signal type according to the body electric system platform by two kinds of dissimilar feedback signals are provided.Separate lock construction element and be arranged in the YE in this technical scheme, when YE damaged or need remove when the car load configuration is adjusted, baggage compartment lock can not use with the traditional approach of pure machinery, and applicability is relatively poor.
Summary of the invention
The utility model mainly is bigger in order to solve the existing baggage compartment lock volume of prior art, weight is heavier, band falls the problem of part or all of mechanical open function after automatically controlled the fractionation, a kind of three-box car baggage compartment lock is provided, it has compact conformation, simple, and automatically controlled part is opened fully independently characteristics with machinery, when YE damages or need remove when the car load configuration is adjusted, baggage compartment lock still can use with the traditional approach of pure machinery, has applicability preferably.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of three-box car baggage compartment lock comprises lock body, YE, ratchet and claw; Described YE is installed on the described lock body and with described claw and is connected; Described ratchet and claw are articulated in closed mouthful of place of described lock body; Described YE comprise one be fixed on motor on the described lock body, a worm screw that is connected with described motor shaft, one with the worm gear and a swing arm that is connected with described worm gear of described worm engaging; Described swing arm is herringbone, and its upper end is provided with the swing arm axis hole and is articulated on the described lock body; Its lower end is respectively equipped with pulling end and opening end, and described swing arm is done contact by described opening end and described claw and is connected.Because described YE and described swing arm all are articulated on the described lock body separately, the dismounting of YE can not influence the use of swing arm, thereby when YE damaged or need remove when the car load configuration is adjusted, baggage compartment lock still can use with the traditional approach of pure machinery.
As a kind of optimal technical scheme of the utility model, be provided with a cam bit in the inner of described worm gear, described cam bit and described worm gear coaxial rotation; Be provided with a swing arm finger in the swing arm between described swing arm axis hole and the described opening end, the profile of described cam bit is done contact with described swing arm finger and is connected under described motor-driven, and promotes described swing arm and described opening end is contacted with described claw work be connected.Do contact by the swing arm finger in described cam bit and described swing arm and be connected, be easier to the dismounting of described YE, and to the influence of described swing arm still less.
As a kind of optimal technical scheme of the utility model, be provided with the backguy groove at the pulling end of described swing arm, on described backguy groove, be provided with the unlatching drag-line; Described swing arm makes described opening end and described claw do contact and is connected under described unlatching drag-line pulling.In the upper end of swing arm the backguy groove is set, is easier to the setting of described unlatching drag-line.
As a kind of optimal technical scheme of the utility model, the molded lines of described cam bit is an evolute.When using YE to open luggage case, move more smooth and easy.
As a kind of optimal technical scheme of the utility model, be provided with a right angle folding surface at described pulling end, described backguy groove is arranged on the described right angle folding surface.Carry out the layout of connecting groove by this right angle folding surface, to adapt to the structural requirement of described lock body.
By the technical solution of the utility model, solved in the prior art, when YE damaged or need remove when the car load configuration is adjusted, baggage compartment lock can not use the problem that applicability is relatively poor with the traditional approach of pure machinery.Described YE is connected as on-fixed with described manually opened swing arm, and all is articulated in independently on the described lock body, has reduced influence each other, makes this lock adapt to the needs of the different configurations of vehicle.
