Description

Description
A servomechanism used to open a lock
The present patent application for industrial invention relates to a servomechanism used to open a lock, in particular the rear door lock of a car trunk.
As it is known, most locks that are currently mounted in vehicles are of power-assisted type, meaning that they incorporate an electrical actuator, often actuated via remote control, to automatically open the lock without key.
Such a lock of known type is provided with a stop hook mechanism to prevent the lock from opening until the open control is given. More precisely, the lock comprises a disk revolving around a support pin with hooked striker. When the rear door of the car is closed, said hooked striker engages with a projection provided on the internal side of the edge of the compartment against which the rear door is stopped at the end of its closing travel.
At least one retention tooth is obtained along the external edge of said disk, being adapted to cooperate with a stop hook having one end pivoted in a fixed pin provided on the frame of the lock. The stop hook is subject to the action of a return spring that constantly pushes it against the edge of the disk, which is in turn subject to the action of a spring that drives it into rotation in the direction that corresponds to the release of the hooked striker from the projection, thus opening the lock and lifting the rear door.
The free end of the stop hook is coupled with the opening device of the rear door, which is adapted to actuate the stop hook - overcoming the resistance offered by the return spring - in such manner to make the stop hook oscillate in the direction that corresponds to its movement away from the disk.
In case of manual opening device of the rear door, the free end of the stop hook is attached to an actuation cable that is put in traction by actuating a lever used to open the rear door situated inside the vehicle driver and passenger compartment. In case of automatic opening device of the rear door, the free end of the stop hook is associated to a slide actuated by an electrical motor, with interposition of a reduction gear, which is started by means of a control button provided inside the vehicle driver and passenger compartment. More precisely, when the electrical motor is started, the lock opens automatically because the slide is translated in such a direction to move the stop hook away from the disk, thus disengaging the retention tooth and stop hook, with consequent movement of the disk towards end of travel position, which corresponds to lock opening.
A lock of this type is illustrated and disclosed in the Italian patent applications MC2005A000012 and MC2007A00038 of the same applicant.
This type of locks for vehicles is impaired by a drawback consisting in the noise generated by the electrical motor, which is especially noted immediately after opening the rear door, when the electrical motor with reduction gear revolves backwards under the action of said slide pushed by a return spring to bring the slide back to idle position. More precisely, said slide is helically coupled with a worm, wherein a reduction gear is splined, directly engaging with a pinion splined on the drive shaft of the electrical motor.
As mentioned above, when the lock is closed, said slide is in idle position interfaced with the free end of said stop hook.
When the electrical motor is started to open the lock, the pinion of the electrical motor drives the gear into rotation, which in turn drives the worm into rotation, with consequent translation of the slide that, during its operating travel, actuates the stop hook and compresses the return spring of the stop hook.
After opening the lock, the motor stops and the slide recovers its idle position, moving backwards under the drive of the return spring that returns to extended position. During the backward travel of the slide, the slide causes the inverse rotation of the drive unit, including worm, gear joined with worm, pinion engaged with gear, drive shaft joined with pinion, and rotor of the electrical motor joined with drive shaft. Consequently, high noise is generated immediately after opening the lock. GB 2 269 435 discloses a servomechanism used to open vehicle locks, comprising an electrical motor with drive shaft with pinion. The motor pinion engages with a gear joined with a worm that pushes a slide to open the lock.
The motor pinion is mounted on a coupling rocker. Two tooth wheels are mounted on the coupling rocker in opposite positions with respect to the motor pinion.
The coupling rocker rotates around the axis of the pinion and therefore the pinion is always in engagement contact with the gear, both when opening and closing the lock. Consequently, after opening the lock, during the backward travel of the slide, the gear causes the inverse rotation of pinion, drive shaft and rotor, thus generating noise. This is confirmed by the fact that the electrical motor is reversible, meaning that it must rotate in both directions. GB 2 269 435 contains no teachings about how to avoid said noise.
Moreover, the two tooth wheels of the coupling rocker only have a guide function during the oscillation of the coupling rocker. Said tooth wheels are not used to enable/disable engagement between pinion and gear. In fact, the pinion always engages with worm gear.
The purpose of the present invention is to find a solution to the aforementioned drawback by designing an improved servomechanism that is noiseless after opening the lock.
A further purpose of the invention is to find a remedy to the problem by introducing simple improvement modifications, leaving the structural configuration and the operating principle of this type of locks and servomechanism unchanged.
Another purpose is to adopt improvement modifications that are reliable, simple and inexpensive to make.
The aforementioned purposes are achieved by the invention with servomechanism having the characteristics of the independent claim 1 .
The servo-mechanism of the invention comprises the parts of a traditional driving unit, with the addition of an idle tooth wheel interposed between said pinion splined on the drive shaft and gear splined on said worm. The pinion is separated from the gear and the idle tooth wheel permanently engages with said pinion.
Said idle tooth wheel is supported by a crank, which is in turn inserted on the drive shaft in such manner that the axis of rotation of said idle tooth wheel is parallel and side-by-side with the drive shaft coinciding with the axis of the pinion splined on the drive shaft.
Said servomechanism also comprises a spring that keeps the idle wheel away from the gear splined on the worm, in such manner that the idle wheel cannot engage with the gear.
When the electrical motor is started, the pinion engages in the idle wheel and simultaneously makes the crank rotate around the axis of the pinion against the spring action. In this way the idle wheel moves closer to the gear and engages with the gear mounted on the worm.
Said crank moves from a first position wherein the idle wheel is not engaged with the worm gear to a second position wherein the idle wheel is engaged with the worm gear. In the first crank position, the pinion is disconnected from the gear; in the second crank position, the pinion is kinematically connected to the gear by means of the idle wheel.
From this general description of the invention it appears clear that, after opening the lock and stopping the motor, said crank rotates around the axis of the pinion under the return action of said spring and the idle wheel is automatically moved away from the worm gear, thus eliminating coupling between idle tooth wheel and worm gear. In view of the above, during the backward movement of the slide mounted on the worm, only the worm and its gear rotate. Instead, idle wheel, pinion, drive shaft, and rotor of the electrical motor do not rotate. Therefore, no noise is generated.
For explanatory reasons, the description of the servomechanism for locks according to present invention continues with reference to the attached drawings, which only have illustrative, not limiting value, wherein:
- Fig. 1 is a perspective view of the main parts of the servomechanism according to the invention associated with a lock; - Fig. 2 is an exploded perspective view of the main parts of the servomechanism according to the invention;
- Fig. 3A is a front view that shows the position of the various parts of the servomechanism according to the invention when the motor is off;
- Fig. 3B is a perspective view that shows the position of the various parts of the servomechanism according to the invention when the motor is on;
Referring to Fig. 1 , the servomechanism of the invention is disclosed, being generally indicated as (A). The servomechanism (A) is preferably associated with a lock (B).
Lock (B) comprises a mechanism with retention hook. Said mechanism with retention hook comprises a hook (1 ) composed of a lever having a first (1 a) and second end (1 b). First end (1 a) of hook is pivoted on a fixed pin (2), whereas second end (1 b) of hook cooperates with servomechanism (A).
Moreover, lock (B) comprises a disk (3) revolving idle around a support pin (4) parallel to fixed pin (2). Said disk (3) comprises a striker (5) adapted to engage with a projection (not shown in the figures) when closing the lock.
At least one tooth (6) is obtained along the external edge of disk (3) and adapted to cooperate with a counter-tooth (7) obtained on hook (1 ). Hook (1 ) is subject to the action of a return spring (not shown in the figure) that constantly pushes it against the edge of disk (3). Disk (3) is subject to the action of its own return spring (not shown in the figure) that drives it into rotation around its pin (4) in the direction shown by the arrow (F) in Fig. 1 . In this way the striker (5) of the disk is released from the counter-tooth (7) of the hook, consequently opening the lock and automatically lifting the rear door by means of traditional pushers used to favor the opening of the rear door.
Also referring to Fig. 2, servomechanism (A) of the invention comprises an electrical motor (100) with drive shaft (101 ) where a pinion (102) is mounted.
A crack (105) is revolvingly mounted on drive shaft (101 ). Crank (105) comprises a pin (104) parallel to drive shaft (101 ). An idle tooth wheel (103) is revolvingly mounted on pin (104) of crank. Pinion (102) permanently engages with idle tooth wheel (103). Said servomechanism (A) also comprises a gear (106) splined on a worm (107) helically coupled with a slide (108). A female screw sliding on worm (107) is obtained in the slide.
Gear (106) is physically separated from pinion (102), meaning that pinion (102) never engages with gear (106).
Crank (105) moves from a first position wherein idle wheel (103) is not engaged with gear (106) of worm to a second position wherein idle wheel (103) is engaged with gear (106) of worm. In the first crank position pinion (102) is disconnected from gear (106); in the second crank position pinion (102) is kinematically connected to gear (106) by means of idle wheel (103).
A first return spring (109) actuates on the slide (108) to keep it in initial position (shown in Fig. 1 ) when the motor is off. Advantageously, the first return spring is a helical spring disposed around worm (107).
Slide (108) comprises a projection (108a). During the operating travel of slide (108), slide (108) compresses first spring (109) and projection (108a) of spring hits and moves second end (1 b) of hook (1 ), thus opening the lock.
The function of first return spring (109) is to bring back slide (108) to initial position, after lock opening.
Said servomechanism (A) also comprises a second return spring (1 10) acting on crank (105). When the electrical motor is off, second return spring (1 10) keeps crank (105) in initial position wherein idle wheel (103) is not engaged with gear (106) (see Fig. 3A).
More precisely, said second return spring (1 10) is a torsional spring and comprises a free end (1 10a) adhering to pin (104) of the crank where idle wheel (103) is pivoted.
Coupling between idle tooth wheel (103) and pin (104) of crank is suitably frictioned, so that idle wheel (103) starts rotating around pin (104) only if pinion (102) transmits to idle wheel (104) a torsional moment higher than resistant torsional moment attributable to friction forces generated by said frictioned coupling. Referring to Fig. 2, according to the preferred embodiment of the present invention, said frictioned coupling occurs by means of a third precompressed spring (1 1 1 ) inserted on pin (104) of crank.
Idle wheel (103) is provided with hub (103a). The third precompressed spring (1 1 1 ) pushes hub (103a) of idle wheel against a shoulder (104a) of pin (104), in such manner to generate friction resistance between hub (103a) and shoulder (104a).
More precisely, third spring (1 1 1 ) is inserted on pin (104) of crank and compressed by a compression dish (1 12) screwed on pin (104) to adjust the precompression load of third spring (1 1 1 ).
When the motor is off, idle wheel (103) is in position shown in Fig. 3A, viz. idle wheel is not engaged with gear (106) of worm.
When motor (100) is started, pinion (102) actuates idle wheel (103). Being unable to rotate around its pin (104) because of friction resistance between hub (103a) and shoulder (104a), idle wheel (103) pushes pin (104) and crank (105). Consequently, idle wheel (103) makes a revolution around drive shaft (101 ) until said idle wheel (103) is engaged with gear (106), as shown in Fig. 3B.
During said revolution of idle wheel (103) around axis of drive shaft, second return spring (1 10) is loaded, and will return to idle position only when motor (100) is stopped.
When idle wheel (103) is engaged with gear (106), idle wheel (103) is forced to stop its revolution around drive shaft (101 ), therefore the torque transmitted by pinion (102) to idle wheel (103) is used to overcome friction resistance between hub (103a) and shoulder (104a) of idle wheel, with consequent rotation of idle wheel (103) around pin (104) of crank.
Consequently, worm (107) is driven into rotation by gear (106), which is temporarily engaged with idle wheel (103). The rotation of worm (107) corresponds to the travel of slide (108), which moves hook (1 ) and compresses first return spring (109).
When slide (108) reaches the end of its working travel, a proximity sensor (not shown in the figure) stops motor (100). As soon as torque on pinion (102) stops, second spring (1 10) is unloaded and recovers its initial idle position, moving pin (104) away from worm (107) with consequent release of idle wheel (1 03) from gear (106), as shown in Fig. 3A.
Said movement of pin (104) away from worm (107) is made possible because crank (105) is free to revolve idle around drive shaft (101 ).
When slide (108) makes its backward travel, being pushed by first spring (109) in extension phase, worm (107) and gear (106) are the only rotating parts, whereas all other parts of the kinematic chain are stopped.
The function of crank (105)-idle tooth wheel (103) assembly is:
- to connect pinion (102) to gear (106) during actuation of motor (100) to open the lock,
- to disconnect pinion (102) from gear (106) at the end of opening phase to allow for backward movement of slide (108) without causing engagement between gear (106) and idle tooth wheel (103), and therefore without causing inverse rotation of pinion (102) and drive shaft (101 ).
In view of the above, with respect to the actuating devices of known type, the disturbing noise caused by the moving gears and revolving parts of electrical motor (100) is eliminated.
Another advantage of the present invention is that less stress is formed on electrical motor (100), the drive shaft (101 ) of which always rotates in the same direction and only for the few moments when the motor is excited, and not after stopping the motor like in the actuating devices of known type, where the drive shaft is driven into inverse rotation until the slide recovers its idle position when the motor is off.
According to an alternative embodiment, instead of providing frictioned coupling between idle tooth wheel (103) and pin (104), said frictioned coupling is obtained between crank (105) and drive shaft (101 ), without altering the aforementioned operating principle.
