Abstract

The present invention relates to an automatic closing device of vehicle door locks, in particular for the rear boot door, which comprises a single toothed wheel (40) and a cursor (60) that cooperate to move the catch of the lock.

Description

Description
Automatic closing device of vehicle door locks.
The present patent application for industrial invention relates to an automatic closing device of vehicle door locks, in particular for rear boot doors.
As it is known, a vehicle door generally comprises a lock that is engaged with a pin provided in the vehicle frame.
For safety reasons, the lock must be provided with two clicks. The first click corresponds to the temporary closing that is obtained by positioning the door on the frame. The second click corresponds to the final closing that is obtained by exerting pressure on the door in order to compress the perimeter gaskets provided on the car door and/or frame.
In recent years sophisticated cars have been provided with a device for automatic closing of the rear boot door.
If the door is simply positioned against the frame, and the lock catch only makes the first click, the automatic device provides for perfect door closing by hooking the catch and dragging it until it makes the second click.
In order to understand the structural configuration of a traditional automatic device of known type, this description continues with reference to two drawings, figs. 1 and 2, which respectively show the front and the back of said device. With reference to fig. 1, said device is composed of an elongated box frame (1 ) (closed by a lid not shown in the figure) provided with a bottom wall (1a) and a perimeter lateral edge (1b).
The frame (1 ) houses an electrical motor (2) with shaft positioned in such a manner that the axis of rotation is parallel to the bottom wall (1a). The tip of the shaft, which protrudes from the motor (2), is provided with a worm (3) that engages with a toothed wheel (4) that rotates on a pin with axis perpendicular to the bottom wall (1a) of the frame (1 ).
The toothed wheel (4) is the first of a series of reduction gears (I) that engage mutually in pairs.
The rotational pin of the last (5) of said gears (I) protrudes outside of the bottom wall (1a) of said box frame (1), where it supports a pulley (6), as shown in fig. 2, with a steel cable (not shown in fig. 2) partially wound on the perimeter groove (6a) provided with enlarged head.
The pulley is provided with a housing (6b) for the enlarged head of the steel cable, which is housed in an ordinary sheath with possibility of sliding with respect to it.
As shown in fig. 2, a bracket (7) is situated on the bottom wall (1a) of the box frame (1) in perpendicular position to said wall (1a) and is provided with a hole (7a) with suitable diameter to prevent the sheath from being inserted through the hole (7a), in such a way that the steel cable is uncovered for the section comprised between the stop hole (6b) and the cross hole (7a).
The other end of the cable is fixed to an oscillating lever, which engages the lock catch during its operational travel and drags it until it makes the second click.
The electrical motor (2) of the device is automatically actuated by means of a proximity sensor, as soon as the lock catch makes the first click, so that the door is perfectly locked also if manual closing is not carried out with sufficient energy to cause the second click of the lock catch.
As soon as the lock catch makes the second click, the electrical motor (2) changes the rotation direction, releasing the cable and allowing the oscillating lever to return to idle position by means of a return spring.
The main inconvenience of said device consists in the fact that, in case of accidental blocking of the device during operation, due to breakage or power failure, the oscillating lever will stop, preventing the backward rotation of the catch, which will remain blocked in intermediate position between the first and second click, thus blocking the lock and the door, without possibility of opening it. In this case, an emergency key must be used to activate the gears (I), being impossible to provide the device with a return spring.
More precisely, if a return spring was provided on the last (5) of the gears (I), the thrust exerted by the spring on the gear would not be sufficient to make the entire series of gears rotate backwards, since the system is of irreversible type, whereas, if a return spring was provided on the first gear (4), it would be necessary to considerably increase the power of the electrical motor (2), with consequent higher cost and larger volume of the device in general.
The latter solution has never been adopted also because no suitable springs are currently available, considering that the first (4) of the reduction gears (I) must make many revolutions for the catch to complete its travel and cause the second lick of the lock.
Another drawback of the aforesaid device consists in the noise caused by the high number of reduction gears (I).
Last, but not least, another drawback of the aforesaid devices consists in the fact that the force of traction exerted by them is constant, whereas the force necessary to close the door completely, with the second click of the lock, is not constant and increases during the deformation of the door gaskets by compression.
The purpose of the present invention is to remedy the aforesaid drawbacks by devising a new automatic closing device of vehicle door locks, which is provided with a simpler structural configuration, is less noisy, is composed of a lower number of gears, is smaller, and, most of all, is equipped with a reversible reduction assembly.
These and other purposes have been achieved by the automatic device of the invention, whose main characteristics are illustrated in the first claim.
The device of the invention comprises a lower box frame, of the type with bottom wall and perimeter lateral edge, and an upper lid adapted to be disposed on said lower box frame.
The frame houses an electrical motor, of the type described above, and one toothed wheel, with teeth engaging with the worm fixed on the tip of the shaft of the electrical motor.
The upper and lower side of the toothed wheel are provided with identical specular grooves with spiral profile.
The frame also houses a Y-shaped fork that slides inside a corresponding guide along the longitudinal axis of symmetry, which is arranged in radial direction with respect to the toothed wheel. The end of a traditional metal cable designed to actuate an ordinary oscillating lever, as the one illustrated above, is fitted to the central arm of the Y-shaped fork.
Moreover, the fork is provided at the ends of the two arms with a coaxial opposite pair of pegs, which are respectively inserted in said pair of said spiral grooves.
The actuation of the work causes the rotation of the toothed wheel and the pegs start sliding inside the corresponding groove, with consequent axial translation of the fork.
From this first, general description of the device of the invention it appears obvious that said device comprises a lower number of parts compared to current devices.
Moreover, the new device allows for changing the ratio between the revolution of the motor and the travel of the metal cable, according to the spiral profile, so that the first part of the fork travel is faster and the second part is slower, thus allowing the fork to exert a stronger force on the metal cable and consequently on the lever and catch.
The device of the invention is provided with two spirals instead of one, namely a first upper spiral and a second lower spiral, and with a fork, instead of a single transmission bracket, in order to distribute loads axially, whereas said loads are not axial in the current devices of known type.
Last, but not least, another advantage consists in the possibility to provide the toothed wheel with a return spring of traditional torsional type.
For purposes of clarity, the description of the automatic closing device of vehicle door locks of present invention continues with reference to the enclosed drawings, which only have an illustrative, not limiting purposes, wherein:
- figures 3 and 4 are an exploded axonometric view of the device of the invention seen from two different angles.
- figures 5 and 6 are a top view of the device of the invention in assembled configuration, without upper lid, respectively in working and idle position. With reference to figs. 3 and 4, the device of the invention comprises:
- a lower box frame (10), of the type comprising a bottom wall (10a) and perimeter lateral edge (10b);
- an upper lid (11) that is fitted above the lower box frame (10);
- a traditional electrical motor (20) with a worm (30) fitted on the shaft; - a toothed wheel (40), with teeth designed to engage with the teeth of the worm (30) and parallel sides (40a and 40b), namely upper (40a) and lower (40b) side, provided with a pair of identical guide grooves (50) with spiral profile;
- a rotational pin (12) of said toothed wheel (40), with ends inserted in an aligned pair of holes (13 and 14), the first one being obtained on the base surface (10a) of the box frame (10) and the second one being obtained on the lid (14);
- a fork (60) that comprises a central arm (61) branching off from a pair of parallel arms (62) provided at the end with a coaxial opposite pair of pegs (63) inserted in the corresponding spiral guide groove (50);
- a return spring (70) for said toothed wheel.
The frame (10) is provided with a compartment (A) for the toothed wheel (40), with rotational pin (12) perpendicular both to bottom wall (10a) and lid (11), which closes the compartment (A) on top. Moreover, the frame (10) is provided with a housing (B) for the electrical motor (20), which is held in such a position that the axis of the worm (30) is tangent to the toothed wheel (40).
Finally, the frame (10) is provided with a guide housing (D) for the alternate travels of the fork (60), which is positioned with its longitudinal axis in radial direction with respect to the toothed wheel (40).
As mentioned above, the pegs (63) slide simultaneously inside the guide groove (50) with spiral profile, moving between two stop positions (P1 and P2), the first one (P1) near the external lateral profile of the toothed wheel (40) and the second one (P2) near the central pin (12).
Finally, it must be noted that the end of the steel cable (80) that is inserted and slide in the ordinary sheath (81) is fitted to the central arm (61) of the fork (60).
With reference to fig. 5, when the device is in idle position, the pegs (63) of the fork (60) are situated in the first stop position (P1 ) and the central arm (61 ) of the fork (60) is in the farthest position with respect to the centre of the toothed wheel (40). As soon as the device is actuated, the electrical motor (20) starts the rotation of the worm (30), which actuates the toothed wheel (40) that makes the pegs (63) slide in the guide grooves (50), with simultaneous centripetal travel of the fork (60) in the guide housing (D).
The centripetal travel of the fork (60) ends as soon as the pegs (63) reach the second stop position (P2) that corresponds to the closest position of the fork (60) with respect to the centre of the toothed wheel (40), as shown in fig. 6.
Once the fork (60) has completed the centripetal travel - with consequent execution of the second click by the lock catch - the electrical motor (20) automatically reverses the direction of rotation, so that, by rotating in the opposite direction, the toothed wheel (40) forces the fork (60) to start and end a centripetal travel until it reaches and stops in idle position, that is to say the farthest position with respect to the centre of the wheel (40).
According to a different embodiment, the device of the invention comprises a return spring (70) designed to drive the toothed wheel (60) backwards in order to return the fork (60) always to idle position, that is to say the farthest position with respect to the centre of the wheel (40).
