Definitions
- the field of the invention is that of the design and manufacture of luggage.
- the field of the invention is more particularly that of opening and closing mechanisms integrated in luggage.
- the opening and closing of an opening relative to a frame on which the opening is movably mounted can be carried out in a purely manual manner such as is traditional in the field of luggage, or else be carried out in a motorized manner such as that this can be seen in other technical fields.
- the sash is conventionally coupled to the frame using a hinge.
- the sash is opened or closed by simply being pivoted around a pivot axis formed by the hinge.
- the mechanism exerts little or no resistance against manipulation of the door by a user.
- a user can easily fold the sash over the frame, thereby changing the sash from an open position to a position folded over the frame.
- Mechanisms with manual actuation are generally provided with means for locking the sash in its folded position on the frame.
- Such locking means can consist of:
- an actuator coupled to the notch to allow it to be retracted from the notch when opening the sash.
- the notch may have a bevel and return means in a projecting position. In this way, when the sash is folded down, it exerts pressure on the notch and pushes it back, thus allowing the sash to pass into its folded position. Arrived in its folded position, the notch is found opposite the notch which, under the effect of the return means, engages in the notch and locks the sash in its folded position.
- the purely manual and mechanical mechanism allows closing of the opening can be done in a natural and intuitive way for a user.
- the motorized mechanism offers automatic closing of the opening without requiring direct user intervention.
- Another objective of the invention is to provide such a piece of luggage which makes it possible to trigger an automatic locking when an opening leaf passes into a folded position on its frame.

- At least one electric motor driving the opening and closing of the opening characterized in that it comprises:
- an electronic unit parameterized with a threshold force S and / or a threshold speed V; and in that the electronic unit is further configured to drive the electric motor so that it drives the opening in the closed position if the force exerted E is greater than or equal to the threshold force S, or if the displacement speed D is greater than or equal to the threshold speed V.
- a user can trigger an automatic closure of the cover by manually initiating this closure.
- the automatic closing via the motor is therefore initiated in a particularly intuitive way.
- This automatic closing is more precisely carried out as soon as the user exerts a sufficient force on the cover.
- the effort is detected thanks to the determination means which make it possible to obtain the force exerted or the speed of movement of the opening resulting from the action of the user.
- the force exerted or the displacement speed are then compared with the threshold force or the threshold speed to allow the triggering of the control of the electric motor by the electronic unit in the case where the exerted force E or the displacement speed D has reached or exceeded at threshold force S or threshold speed S.
- This automatic closing by the electric motor also ensures the correct passage in the closed position of the opening.
- the cover falling on the box can be sudden, at the risk of gradually degrading the baggage.
- the automatic closing of the luggage cover according to the invention avoids these situations.
- a user manually initiates the closing the latter is completed in a certain and controlled (non-abrupt) manner by the electric motor, and the user can grab the baggage and move it without the risk of unexpected opening.

- the determining means comprise a first position sensor of a member of the hinge, called "Witness member"
- the determining means being configured to calculate the force exerted E from a displacement of the witness member generated by the application of the force on the opening as well as a resistance to this displacement exerted by the electric motor, and / or calculate the speed of movement of the opening from a movement of the control member generated by the application of the force on the opening.
- the position of the control member makes it possible to determine the position of the opening relative to the frame, as well as the changes in the position of the opening relative to the frame thanks to changes in the frame. position of this witness body.
- the hinge comprises:
- a mechanism for converting a rotational movement of the electric motor into a translational movement comprising a transmission member movable in translation along a translation axis T; - a coupling member coupled by a first of its ends to the opening on a first pivot point eccentric to an axis of rotation of the opening, and at a second of its ends to the transmission member on a second pivot point, a translation of the transmission member in a first direction causing an opening of the leaf, and a translation of the transmission member in a second direction causing a closing of the leaf; the transmission member forming the control member.
- This design of the hinge allows the witness member to be formed by a member of the conversion mechanism allowing the movement produced by the electric motor to be transmitted to the sash.
- the opening is:
- the electronic unit is further configured to drive the electric motor so that it tends to maintain the opening in its intermediate open position by exerting a resistance R going against a translation of the opening in its intermediate open position to its closed position, with resistance R equal to the threshold force S.
- the opening has a position close to its closed position, which it tends to maintain.
- Such an intermediate opening position can make it possible, for example, to prevent the opening from adopting a position in which it can be very difficult to grasp by a user, for example to interrupt its closing or to reopen it.

- the second sensor (s) are positioned in close proximity to a front edge of the frame, opposite a rear edge of the frame, the hinge being positioned in the frame on the side of the rear edge of the frame.
- This design compensates for the leverage phenomenon and the appearance of a parasitic moment in the event that a person exerts a force on a part of the sash that is opposite the hinge.
- the positioning of one or more second sensors in the immediate vicinity of the front edge of the frame makes it possible to compensate for this parasitic moment and to ensure that the force applied to the opening is correctly determined.
- the second sensor (s) are Hall effect sensors
- the opening door carries one or more magnets positioned opposite the Hall effect sensor (s).
- Such Hall effect sensors make it possible to determine the position of the sash relative to the frame thanks to the ability of these sensors to determine the position of an object through magnetic fields.

- the second sensor 52 is a Hall effect sensor and a magnet 520 complementary to the Hall effect sensor is carried by the opening opposite the second sensor 52.
- Such a Hall effect sensor makes it possible to measure a variation in the magnetic field and thus makes it possible to detect the position of the magnet 520 relative to the second sensor 52 and thus to determine the position of the opening 1 relative to the front edge 201 of the frame 200.
- the determination means 5 are then configured to correlate a signal from the second sensor 52 generated by the application of a force on the sash 1 in its intermediate opening position to the force exerted E.
- such a second sensor 52 makes it possible to compensate for the presence of a parasitic moment, resulting from a leverage effect, in the case where a first force F1 is applied to a front part of the opening 1
- a force F1 is applied to a front part of the opening 1
