Description

The present invention relates to a device for power supply and control of an electric motor for driving a movable gate element, in particular a gate leaf. The invention also relates to a drive system for a movable gate element, in particular a gate leaf, comprising such a power supply and control device. The invention also relates to a home automation system comprising such a system. The invention finally relates to a method of operating such a power supply and control device.

It is known to provide an electromechanical system for manipulating one or more movable elements of a gate closing a property or land.

Such an electromechanical system generally comprises an actuator of one or more of the movable elements and a control device making it possible to supply the actuator and thus to translate control commands received from a user into movement actions of the element or elements. mobile. Such an electromechanical system is powered by the commercial electrical network. In some cases, such a system is problematic. In particular, in the event of a power failure, the electromechanical system is no longer powered and it is no longer possible to supply the actuator to operate the mobile element or elements. To remedy this problem, it is common to provide the electromechanical system with a backup battery for, at least temporarily, to power the actuator and thus to maneuver the movable elements.

However, in some cases, due to economic constraints and / or congestion, it is not possible to provide a battery or, in other cases, including prolonged power outage, the capacity of the battery is insufficient to operate the moving element (s) for a desired period. A failure of the control electronics of the system is also problematic. To remedy these problems, it is planned to disengage the electromechanical system of the movable element or elements so as to be able to maneuver it or these manually. Unfortunately, for obvious reasons of safety but also for reasons of architecture of the system, the means for disengaging the electromechanical system are arranged inside the enclosure, so that they are easily accessible only from inside the enclosure. These means could be arranged outside, but the complexity of the architecture and the cost of disengaging means would be unacceptable. Therefore, it appears a problem when the user, wishing to control the opening of the gate, is outside the enclosure and the electromechanical system does not respond to a command order opening the gate. Indeed, in such a case, it has no other solution than to cross the enclosure to disengage the electromechanical system.

The object of the invention is to provide a power supply device of an electric motor to overcome the problems mentioned above and improving the power supply devices known from the prior art. In particular, the invention proposes a power supply device making it possible to control an opening of a gate even in the absence of power supply by the commercial electrical network or in the absence or in the event of failure of a battery of backup installed at the gate.

The device may comprise a first removable connection element to the auxiliary supply source, in particular a socket, the connection terminals to the auxiliary power supply source being able to be located at the level of the first connection element. The device may comprise an element for adapting the power and / or the current and / or the supply voltage supplied by the auxiliary source. The matching element may comprise a power and / or current limiting element and / or the power supply voltage supplied by the auxiliary source.

The device may comprise an electrical switching element electrically connecting the power supply terminals of the electric motor to the terminals for connection to the auxiliary source of power supply of the motor vehicle battery type, in particular an electrical switching element making it possible to control only opening of the gate member or controlling opening and closing of the gate member. The electrical switching element may be a key switch and / or a dead-man switching element. The device may include a disconnect element of the main power source disconnecting the main power source when the auxiliary power source is connected to the device. The device may include a housing member for a connection cable to the auxiliary power supply source. The power supply output terminals of the electric motor may be arranged such that they are not accessible from the outside of an enclosure closed by the gate, in particular the power supply output terminals of the electric motor and the terminals of the electric motor. connection to the auxiliary power supply source of motor vehicle battery type being arranged at substantially opposite locations of the device or the power supply output terminals of the electric motor can be arranged under a removable protection with the aid of a tool, especially using a special tool.

Other features and advantages of the present invention will emerge from the description given below, with reference to the figures which illustrate embodiments having no limiting character.

Figure 1 is a diagram of a first embodiment of a home automation system according to the invention. Figure 2 is a diagram of a second embodiment of a home automation system according to the invention. A first embodiment of a home automation system 20 according to the invention is described below with reference to FIG.

The home automation installation 20 is preferably a motorized gate installation 5 for example a motorized gate installation to a movable element, in particular to a leaf or leaf or to a sliding element, or a motorized gate installation with two movable elements 3, 4, in particular with two leaves. In Figure 1, a motorized portal system 5 with two leaves 3, 4 is shown.

The home automation installation preferably comprises a gate 5 and a system 30 for driving the movable element or movable elements 3, 4 of the gate. In the case where the gate comprises two movable elements, the drive system can obviously include separate motors to maneuver each of the moving elements. However, for the sake of simplification, only one of the motors, the one having the function of driving the movable element 3, is shown in FIG. 1. In this embodiment, the movable elements 3 and 4 are, for example, leaves. A motor vehicle 100 is not part of the home automation system.

The drive system 30 of an element 3 of the gate 5 comprises an electric motor 2 for driving the movable element 3 and a device 1 for supplying and controlling the electric motor 2. In addition, the system can comprise a connecting cable 15 to an auxiliary power supply source 10. The electric motor 2 is preferably a DC electric motor, for example a 24 V DC electric motor. Similar solutions can be envisaged for others. types of motors, including AC or universal motors and / or other voltage values. Preferably, the cable comprises, at a first of these ends, a removable connection element 16 allowing the removable connection of the supply device 1 to the auxiliary supply source 10. For example, the removable connection element 16 may comprising a first male plug, respectively female, intended to cooperate with a second female plug, respectively male, to connect or electrically connect the auxiliary power supply to the power supply device. The second plug is part of a removable connection element 11 included in the supply device 1. Alternatively, the cable can be electrically connected permanently to the power supply device. In this case, a housing element must be provided to store the cable. Such an element is mentioned below. The cable may furthermore, at a second of these ends, comprise another element 17 of removable connection to the auxiliary source of power supply 10. This plug is preferably a male electrical plug of cigarette lighter type compatible with the devices of Cigarette lighter 18 for motor vehicles 100 or compatible with any other automotive interior power socket standard. Indeed, the auxiliary power supply source 10 is an electric battery of a motor vehicle 100. More generally, the auxiliary power supply source can be a portable battery of any type. Most of the users arriving at the gate to cross it have a motor vehicle equipped with a battery 10. In such a motor vehicle, the battery is connected via wiring 19 to a cigarette lighter 18 and / or to another power supply of the same standard or another standard. The cable may additionally or alternatively have any other element allowing an electrical connection to a motor vehicle battery, including clamps. The power supply device 1 for the electric motor 2 for driving the movable element 3 of the gate 5 comprises output terminals 6 for supplying electric power to the electric motor, connection terminals 7 for a main power supply source. 8 and connection terminals 9 to the auxiliary power source 10.

The power supply device comprises, for example, a control element 41, an interface element 42 and an electrical switching element 13. The interface element makes it possible to interface the power supply output terminals 6, control element 41, the electrical switching element 13 and the connection terminals 9 to the auxiliary power supply source 10. The control element 41 can be supplied, via connection terminals 7, by the main power source. 8. The control element 41 mainly serves to supply the motor in response to control commands issued by the user in a normal operating situation of the system. Orders are issued for example from remote control points connected by wire or by non-wire way, including radio, to the control element. Indeed, in this situation, the supply voltage of the motor is supplied to the terminals "Motor 1" of the control element. Moreover, in this situation, the electrical switching element 13 can also be used to translate control commands of the user. Indeed, according to the action of the user on the electrical switching element 13, different terminals of the control element 41 are electrically connected and this is interpreted at the control element 41. It follows that the voltage at the terminals "Motor 1" depends on the interpretations. These interpretations can in particular be made at the level of a logical processing unit 44.

The interface element 42 mainly comprises a connection detection element 43 of the auxiliary power supply source 10, switches 14, 141, an adapter element 12 of the power and / or the electric power supply current. provided by the auxiliary source and possibly a fuse 45. The sensing element and the switches constitute a relay. Indeed, when a voltage appears across the detection element, the switches 14, 141 go from the state shown in Figure 1 to their other switching state. It follows that the motor 2 can no longer be powered from the control element 41, but can only be powered by the auxiliary power supply source 10 through the electrical switching element 13 and the element 12 for adapting the power and / or the current and / or the power supply voltage. The adaptation element advantageously comprises an element 121 for limiting the power and / or the current and / or the power supply voltage. In particular, this limiting element is active when starting the engine (where a peak of power conventionally occurs) and / or when arriving at the end of the race or an arrival against an obstacle (where it is located. also classically produces a peak of power called). This element can provide personal protection in accordance with the standard for obstacle detection. In the event of a rapid current rise detection, the matching element 12 and / or the limiting element 121 cut off the power supply to the motor. One can also imagine that the resumption of movement is only if the user makes a particular maneuver on the electrical switching element: a passage in an original position for example. Examples of electrical switching element are given below. The supply of the motor 2 by the auxiliary power supply source 10 is advantageously moreover through a fuse 45. This protects the auxiliary supply source, in particular the electrical circuit of the vehicle. For this, the fuse is advantageously more sensitive and / or faster than the fuse located in the vehicle between the battery and an electrical outlet 18. Note that, in this embodiment, a single state of the element 13 electrical switching allows to power the electric motor 2 with the auxiliary power supply. The motor 2 can only rotate in one direction when it is powered by the auxiliary power supply. It follows that, in this situation, the action of the engine can only open the gate.

The element 12 for adapting the power and / or the power supply current makes it possible to avoid damaging the electrical circuit of the motor vehicle 100 in which the auxiliary source of power supply is located. Fuse 45 provides additional protection.

Advantageously, the interface element 42 comprises a removable connection element 11 already mentioned above, for example a socket, the connection terminals 9 to the auxiliary power supply source being at the level of the element 11 of FIG. connection.

As previously seen, the electrical switching element 13 electrically connects the power supply output terminals 6 of the electric motor to the connection terminals 9 to the auxiliary power supply source 10. Advantageously, the electrical switching element is a key switch. Preferably, the operation is of the man-dead type, that is to say that the motor is activated only as long as an action is maintained on the electrical switching element. As previously seen, the contactors 14 are part of a disconnect element of the main power source disconnecting the main power source when the auxiliary power source is connected to the device. Advantageously, the supply device 1 comprises a housing element 46 of the connection cable 15 to the auxiliary power supply source. Alternatively, the housing member may be out of the feeder. However, the housing element can be part of the drive system 30, or even be out of the drive system but be part of the home automation system 20. This housing element can be in particular in a pillar supporting the portal. Advantageously, the housing element is closed by a lockable door with a key. Advantageously, this key is the same as that for operating the key switch element. The housing element can be in a mailbox or be a compartment of a mailbox. The cable can also be stored in the motor vehicle. In the latter case it is a connection element 11 which can be placed advantageously in a housing such as the mailbox. Advantageously, the output terminals 6 of electric motor power supply are arranged so as not to be accessible from outside the enclosure closed by the gate. Indeed, it is interesting that the connection element 13 can not be shunted. For example, the power supply output terminals 6 of the electric motor and the connection terminals 9 to the auxiliary power supply source 10 are arranged at substantially opposite locations of the power supply device. Alternatively, the output terminals 6 of electric motor power supply can be arranged under a removable cover, for example a hood using a tool, in particular using a special tool.

One embodiment of an operating method of a feed device 1 according to the invention is described below. It is assumed that the main source of power supply is faulty. The user saw this failure. He then decides to use as an auxiliary source of power the battery of his motor vehicle 100. In a first step, the user deploys the cable 15 and connects an electrical outlet 18 of the motor vehicle to the power terminals 9.

Thus, the auxiliary source of power supply is connected to the power supply terminals 9.

In a second step, the detection element 43 detects the presence of a voltage at the terminals 9. This causes the switches 14, 141 to switch from their state shown in FIG. 1 to their other state. This also causes the disconnection between the terminals 6 and terminals "Motor 1" of the control element 41. In a third step, the user acts on the switching element 13. The motor 2 is again powered by the auxiliary source power supply. The motor then causes the opening of the movable element 3 of the gate 5. In a fourth step, the user disconnects the auxiliary power source of the terminals 9, for example at the plugs 17 and 18. It is then that the detection element is deactivated and that the switches 14 and 141 return to their state shown in FIG. 1. In a fifth step, the user can enter the enclosure at the gate and disengage the motors, particular the motor 2, for driving the movable elements of the portal.

A second embodiment of a home automation system 20 'according to the invention is described below with reference to FIG. 2. The home automation installation 20' differs from the home automation installation previously described only by its switching element 13 ' and, consequently, by the wirings of the interface element 42 '. Indeed, in this embodiment, the switching element 13 'and the wiring are such that it is possible once the auxiliary power supply source connected to the terminals 9 to control the opening and closing of a element of the portal.

The system 30 'differs from the system 30 in the same way. The feeder 1 'differs from the feeder 1 in the same way. It is possible that the voltage of the auxiliary power supply source has a voltage, for example 12 V, different from the nominal power supply voltage of the 24 V motor. This is not very troublesome since the motor powered by the voltage of the auxiliary power supply makes it possible to actuate the motor and therefore the movable gate element to which it is mechanically connected.

Advantageously, the interface element is configured so that the switching element 13 makes it possible to control the activation of the motor and therefore the operation of the mobile element when the power supply device is powered by the main power source. power supply or when the supply device is operating normally and so that the switching element allows to control the activation of the motor and therefore the operation of the movable element when the supply device is powered by the auxiliary power source. power supply. In the latter case, the possibility of control can be limited to a single direction of movement of the movable element. When the power supply device is powered by the main power supply source or when the power supply device is operating normally, the interface element advantageously cooperates with the control element 41 to control the activation of the motor and therefore the operation of the movable element.
