Abstract

The lock carriage assembly has a rack attached driving a brake pinion to control its movement. The electric actuator comprise a box (2) housing an electric motor (3) which is linked to drive a worm screw (5) coupled to an output pinion (4). This is able to rotate a nut (7) through which a screw passes. This in turn moves a carriage through the intermediary of an elastic device (9,11), with a locking lever (12) coupled to the carriage. The carriage is provided with a braking mechanism consisting of a rack (14) which is fixed laterally to the carriage. This engages a brake pinion which serves to reduce the speed of displacement of the carriage and thus minimize the noise of impact at the end of the movement of the locking mechanism.

Description

La présente invention a pour objet un actionneur électrique de condamnation pour serrure de véhicule. The present invention relates to an electric actuator for locking a vehicle lock.

Cet actionneur comprend un boîtier contenant un moteur électrique, une vis réversible accouplée à un pignon de sortie du moteur et pouvant être entraînée en rotation par celui-ci, un écrou traversé par la vis, bloqué en rotation et pouvant entraîner en translation un chariot par linter- médiaire de moyens élastiques, ainsi qu'un levier de renvoi de condamnation accouplé au chariot. This actuator comprises a housing containing an electric motor, a reversible screw coupled to a motor output pinion and which can be driven in rotation by the latter, a nut through which the screw passes, locked in rotation and which can drive a carriage in translation. the intermediary of elastic means, as well as a locking return lever coupled to the carriage.

Ces actionneurs de condamnation, réversibles ou débrayables, sont fixés sur la serrure correspondante. These reversible or disengageable locking actuators are fixed to the corresponding lock.

En général, ces actionneurs utilisent des moteurs dont les vitesses de rotation sont très élevées. Ces moteurs génèrent donc dans les actionneurs des mouvements internes rapides, qui produisent des bruits d'impacts en fin de mouvement du chariot. In general, these actuators use motors whose rotational speeds are very high. These motors therefore generate rapid internal movements in the actuators, which produce impact noises at the end of the carriage movement.

La présente invention a pour but de limiter ces bruits d'impacts. The object of the present invention is to limit these impact noises.

Conformément à l'invention, le chariot est muni de moyens de freinage pour réduire les bruits d'impacts consécutifs aux courses du chariot. According to the invention, the carriage is provided with braking means to reduce impact noise consecutive to the strokes of the carriage.

Suivant un mode de réalisation avantageux, lesdits moyens de freinage comprennent une crémaillère fixée latéralement au chariot, et un pignon-frein, fixé au boîtier, qui coopère avec la crémaillère. According to an advantageous embodiment, said braking means comprise a rack fixed laterally to the carriage, and a pinion-brake, fixed to the housing, which cooperates with the rack.

- Ainsi, lorsque le chariot est entraîné par des moyens élastiques comprimés par écrou, la crémaillère entraîne en rotation le pignon du frein-pignon, qui oppose un couple résistant au déplacement du chariot. - Thus, when the carriage is driven by elastic means compressed by nut, the rack rotates the pinion of the pinion brake, which opposes a torque resistant to the movement of the carriage.

L'invention sera maintenant décrite en référence au dessin annexé qui en illustre une forme de réalisation à titre d'exemple non limitatif. The invention will now be described with reference to the accompanying drawing which illustrates an embodiment thereof by way of non-limiting example.

- la Fig.Unique est une vue en perspective, sensiblement à l'échelle, d'une forme de réalisation de l'actionneur électrique de condamnation selon l'invention. - The Fig.Unique is a perspective view, substantially to scale, of an embodiment of the electric locking actuator according to the invention.

L'actionneur électrique de condamnation illustré au dessin, est destiné à être associé à une serrure de véhicule non représentée, pour condamner ou décondamner celle-ci dans sa position de verrouillage.  The electric locking actuator illustrated in the drawing is intended to be associated with a vehicle lock, not shown, for locking or unlocking the latter in its locked position.

Cet actionneur 1 comprend un boîtier constitué de deux demi-coquilles en matière plastique dont l'une, formant un couvercle 2, est représentée. Ce couvercle 2 contient un moteur électrique 3 dont l'arbre de sortie est équipé d'un pignon 4, et une vis réversible 5 munie d'une roue dentée 6 accouplée au pignon 4, dont la rotation peut ainsi faire tourner la vis 5 autour de son axe. This actuator 1 comprises a housing consisting of two plastic half-shells, one of which, forming a cover 2, is shown. This cover 2 contains an electric motor 3, the output shaft of which is fitted with a pinion 4, and a reversible screw 5 provided with a toothed wheel 6 coupled to the pinion 4, the rotation of which can thus make the screw 5 rotate around of its axis.

L'actionneur comprend également un écrou 7 traversé par la vis 5, bloqué en rotation par les parois latérales d'un chariot 8 dans lequel il est disposé et qui contient la vis réversible 5. De part et d'autre de l'écrou 7 sont disposés des moyens élastiques constitués par des ressorts hélicoïdaux respectifs 9,11 coaxiaux à la vis 5. The actuator also comprises a nut 7 through which the screw 5 passes, locked in rotation by the side walls of a carriage 8 in which it is disposed and which contains the reversible screw 5. On either side of the nut 7 there are elastic means constituted by respective helical springs 9, 11 coaxial with the screw 5.

L'extrémité du chariot 8 est articulée sur un levier de renvoi 12 pourvu d'un secteur denté 13 qui coopère avec un levier de condamnation non représenté, de manière connue en soi. The end of the carriage 8 is articulated on a return lever 12 provided with a toothed sector 13 which cooperates with a not shown locking lever, in a manner known per se.

Le chariot 8 est muni d'une crémaillère 14 fixée latéralement au chariot, du côté de celui-ci opposé au moteur électrique 3. La denture de la crémaillère 14 engrène avec un pignon 15 d'un pignon-frein 16, réalisé de manière connue en soi par un dispositif à accouplement visqueux. Le pignonfrein 16 est fixé au couvercle 2 par des pattes latérales 10, de manière appropriée, par exemple par des vis. Ce pignon-frein comprend un pignon 15 monté rotatif autour d'un axe 17. The carriage 8 is provided with a rack 14 fixed laterally to the carriage, on the side of the latter opposite the electric motor 3. The teeth of the rack 14 mesh with a pinion 15 of a brake pinion 16, produced in known manner per se by a viscous coupling device. The pinion 16 is fixed to the cover 2 by lateral tabs 10, in an appropriate manner, for example by screws. This brake pinion comprises a pinion 15 rotatably mounted about an axis 17.

L'actionneur qui vient d'être décrit fonctionne de la manière suivante. The actuator which has just been described operates in the following manner.

Lorsque l'actionneur est alimenté électriquement, le moteur 3 entraîne en rotation son pignon 4, qui entraine à son tour en rotation la roue dentée 6 et la vis 5. When the actuator is electrically powered, the motor 3 rotates its pinion 4, which in turn drives the toothed wheel 6 and the screw 5.

La rotation de cette dernière déplace l'écrou 7 en translation dans le chariot 8. L'écrou 7 comprime l'un des deux ressorts 9 et 11, selon le sens de rotation du moteur et de la vis 5. En fin de compression, le ressort 9 ou 11 entraîne en translation le chariot 8. La crémaillère 14 entraîne alors en rotation le pignon 15 du frein-pignon 16, qui oppose un couple résistant de freinage à la translation du chariot 8.  The rotation of the latter moves the nut 7 in translation in the carriage 8. The nut 7 compresses one of the two springs 9 and 11, according to the direction of rotation of the motor and of the screw 5. At the end of compression, the spring 9 or 11 drives the carriage 8 in translation. The rack 14 then rotates the pinion 15 of the pinion brake 16, which opposes a resistant braking torque to the translation of the carriage 8.

L'opposition au déplacement du chariot 8 réduit sa vitesse de déplacement dans les deux sens. En raison de la réduction de cette vitesse de déplacement, les bruits d'impacts générés normalement par l'arrêt du mouvement du chariot 8 et du renvoi de chariot 12 sont minimisés. Opposition to the movement of the carriage 8 reduces its speed of movement in both directions. Due to the reduction in this speed of movement, the impact noise normally generated by stopping the movement of the carriage 8 and the carriage return 12 are minimized.

En variante, le système crémaillère 14 et pignonfrein 16 peut être remplacé par tout moyen équivalent, assurant un freinage du chariot 8.  As a variant, the rack 14 and pinion brake 16 system can be replaced by any equivalent means, ensuring braking of the carriage 8.
