Description

DISPOSITIF DE COMMANDE POUR MOTEUR ELECTRIQUE D’UN PULSEUR  CONTROL DEVICE FOR AN ELECTRIC MOTOR OF A PULSE
D’AIR DE VEHICULE AUTOMOBILE  MOTOR VEHICLE AIR
L’invention concerne un dispositif de commande pour un moteur électrique, notamment d’un pulseur d’air pour un dispositif de ventilation, de chauffage et/ou de climatisation de véhicule automobile. The invention relates to a control device for an electric motor, in particular an air blower for a ventilation, heating and / or air conditioning device of a motor vehicle.
Il est connu qu’un tel dispositif de ventilation, de chauffage et/ou de climatisation permet la régulation de la température d’un flux d’air destiné à alimenter l’habitacle du véhicule. Le pulseur d’air permet, quant à lui, de faire entrer et circuler le flux d'air dans le dispositif de ventilation, de chauffage et/ou de climatisation jusqu’à des bouches de sortie, où l’air pénètre dans l’habitacle. It is known that such a ventilation, heating and / or air conditioning device makes it possible to regulate the temperature of an air flow intended to supply the passenger compartment of the vehicle. The air blower allows the air flow to enter and circulate in the ventilation, heating and / or air conditioning system up to the outlet vents, where the air enters the cockpit.
Le pulseur comporte généralement un moteur électrique, notamment à balais, sur lequel est montée une roue pour mettre l’air en mouvement. Le pulseur comporte également un support moteur dans lequel est logé le moteur électrique, ainsi que le dispositif de commande du moteur électrique, le moteur et le dispositif de commande étant connectés l’un à l’autre. The blower generally comprises an electric motor, in particular with brushes, on which a wheel is mounted to set the air in motion. The pulser also includes a motor support in which the electric motor is housed, as well as the electric motor control device, the motor and the control device being connected to each other.
Par exemple, le dispositif de commande est muni d’un connecteur de puissance mâle tandis que le moteur électrique comprend un faisceau électrique et un connecteur de puissance femelle. Le connecteur mâle s’emmanche dans le connecteur femelle, ce qui relie électriquement le dispositif de commande et le moteur. For example, the controller has a male power connector while the electric motor includes an electrical harness and a female power connector. The male connector fits into the female connector, which electrically connects the control device and the motor.
Néanmoins, un tel pulseur présente l’inconvénient que l’ensemble du moteur, du dispositif de commande, de leur connecteur et du support moteur peut être encombrant dans le véhicule, ce qui n’est bien entendu pas optimal selon le type de véhicule que le pulseur équipe. However, such a blower has the disadvantage that the entire engine, the control device, their connector and the engine support can be bulky in the vehicle, which is of course not optimal depending on the type of vehicle that the team kicker.
De plus, la connexion entre le moteur et le dispositif de commande doit être la plus fiable possible, afin d’éviter tout dysfonctionnement du pulseur, qui générerait un dysfonctionnement du dispositif de ventilation, chauffage et/ou climatisation et impacterait nécessairement le confort des usagers du véhicule. Or, selon la position du connecteur dans le véhicule, le dispositif de commande et le moteur peuvent s’éloigner inopportunément l’un de l’autre, ce qui peut occasionner une dégradation de leur connexion électrique. En effet, les pertes par échauffement sont d’autant plus importantes que le faisceau électrique est long. D’autre part, le dispositif de commande peut comporter un ou plusieurs composants électroniques comportant deux pattes de connexion, et brasés sur un circuit imprimé selon la technique dite du montage en surface. On entend par le terme « montage en surface » que le composant est brasé sur la surface du circuit imprimé. Dans le cas où le composant électronique possède des pattes de connexion, celles-ci ne traversent pas le circuit imprimé, par conséquent celui-ci ne possède aucun trou d’insertion des pattes de connexion. Une difficulté de ce type de montage est d’assurer la qualité de la brasure même lorsque le composant à braser présente de légers défauts géométriques, comme deux pattes de connexion non tout à fait coplanaires. In addition, the connection between the motor and the control device must be as reliable as possible, in order to avoid any malfunction of the blower, which would generate a malfunction of the ventilation, heating and / or air conditioning device and would necessarily impact user comfort. of the vehicle. However, depending on the position of the connector in the vehicle, the control device and the motor may move away from one another inappropriately, which can cause deterioration of their electrical connection. Indeed, the losses by heating are all the more important as the electric beam is long. On the other hand, the control device can comprise one or more electronic components comprising two connection tabs, and soldered on a printed circuit according to the technique known as surface mounting. The term “surface mounting” is understood to mean that the component is soldered to the surface of the printed circuit. In the case where the electronic component has connection tabs, these do not pass through the printed circuit, consequently the latter does not have any insertion holes for the connection tabs. One difficulty with this type of mounting is to ensure the quality of the solder even when the component to be brazed has slight geometric defects, such as two connection tabs which are not entirely coplanar.
En effet, dès que les pattes de connexion de l’un des composants ne sont pas tout à fait coplanaires, leur soudure sur le circuit imprimé est fragilisée et peut se rompre durant la vie du véhicule, sous l’effet notamment des vibrations auxquelles le produit est soumis au cours de son utilisation.  In fact, as soon as the connection tabs of one of the components are not entirely coplanar, their soldering on the printed circuit is weakened and can break during the life of the vehicle, notably under the effect of vibrations to which the product is subject to during use.
Le but de l’invention est de remédier au moins partiellement à ces inconvénients. The object of the invention is to at least partially remedy these drawbacks.
A cet effet, l’invention a pour objet un dispositif de commande pour un moteur électrique comprenant une carte de circuit imprimé, ladite carte de circuit imprimé étant munie d’un composant électronique comportant au moins deux pattes, au moins l’une des pattes étant montée en surface de la carte de circuit imprimé et une autre des pattes étant montée traversante de ladite carte de circuit imprimé. To this end, the subject of the invention is a control device for an electric motor comprising a printed circuit board, said printed circuit board being provided with an electronic component comprising at least two legs, at least one of the legs being mounted on the surface of the printed circuit board and another of the tabs being mounted through said printed circuit board.
Ainsi, le composant partiellement traversant et partiellement monté en surface permet de s’affranchir des défauts de localisation dans un même plan des pattes de connexion. En effet, la disposition relative d’une patte de connexion par rapport à l’autre n’est pas importante pour assurer un bon contact entre la patte de connexion devant être brasée sur la surface du circuit imprimé et le circuit imprimé lui-même. Thus, the partially traversing and partially surface-mounted component makes it possible to overcome localization defects in the same plane of the connection tabs. Indeed, the relative arrangement of a connection tab relative to the other is not important to ensure good contact between the connection tab to be soldered on the surface of the printed circuit and the printed circuit itself.
De plus, cette configuration rend possible d’intégrer le dispositif de commande sur le moteur, ce qui réduit la distance entre des balais et un collecteur du moteur ainsi que la distance du faisceau électrique. Selon une autre caractéristique de l’invention, le composant électronique possède deux pattes. En d’autres termes, le composant électronique comprend deux pattes uniquement. In addition, this configuration makes it possible to integrate the control device on the motor, which reduces the distance between the brushes and a motor manifold as well as the distance from the electric harness. According to another characteristic of the invention, the electronic component has two tabs. In other words, the electronic component includes only two legs.
Selon une autre caractéristique de l’invention, le dispositif comprend une liaison électrique sertie avec la patte traversante du composant électronique. According to another characteristic of the invention, the device comprises an electrical connection crimped with the through lug of the electronic component.
Ainsi, grâce à la présente invention, il est possible de s’affranchir de tout connecteur mâle/femelle entre le dispositif de commande et le moteur électrique et rend très fiable la connexion électrique entre le dispositif de commande et le moteur électrique. Thus, thanks to the present invention, it is possible to dispense with any male / female connector between the control device and the electric motor and makes the electrical connection between the control device and the electric motor very reliable.
Selon une autre caractéristique de l’invention, la liaison électrique comprend un fil tressé. According to another characteristic of the invention, the electrical connection comprises a braided wire.
Selon une autre caractéristique de l’invention, la liaison électrique est conformée pour connecter électriquement le composant électronique à un balai du moteur électrique. According to another characteristic of the invention, the electrical connection is shaped to electrically connect the electronic component to a brush of the electric motor.
Selon une autre caractéristique de l’invention, le composant électronique est une bobine ou un condensateur ou une résistance ou un transistor ou une diode. According to another characteristic of the invention, the electronic component is a coil or a capacitor or a resistor or a transistor or a diode.
Selon une autre caractéristique de l’invention, la carte de circuit imprimé comprend un passage de la patte traversante du composant électronique, le passage étant une encoche formée dans un bord de la carte de circuit imprimé ou un trou traversant. According to another characteristic of the invention, the printed circuit board comprises a passage of the through lug of the electronic component, the passage being a notch formed in an edge of the printed circuit board or a through hole.
Selon une autre caractéristique de l’invention, le passage présente une forme générale circulaire ou oblongue ou rectangulaire ou carrée. According to another characteristic of the invention, the passage has a general circular or oblong or rectangular or square shape.
Selon une autre caractéristique de l’invention, la patte traversante forme un angle compris entre 88° et 92° avec un plan dans lequel s’étend la carte de circuit imprimé, de préférence 90°. According to another characteristic of the invention, the through tab forms an angle between 88 ° and 92 ° with a plane in which the printed circuit board extends, preferably 90 °.
L’invention a également pour objet un pulseur d’air pour un dispositif de dispositif de ventilation, de chauffage et/ou de climatisation de véhicule automobile, comprenant un dispositif de commande tel que décrit précédemment. The invention also relates to an air blower for a device for the ventilation, heating and / or air conditioning device of a motor vehicle, comprising a control device as described above.

L’invention a pour objet un dispositif de commande, référencé 1 dans les figures. L’invention a également pour objet un pulseur (non illustré) comprenant le dispositif de commande 1 ainsi qu’un moteur électrique configuré pour être commandé par le dispositif de commande 1. The subject of the invention is a control device, referenced 1 in the figures. The invention also relates to a pulser (not illustrated) comprising the control device 1 as well as an electric motor configured to be controlled by the control device 1.
L’invention a également pour objet un dispositif de ventilation, de chauffage et/ou de climatisation pour un véhicule automobile (non illustré) équipé du pulseur muni du dispositif de commande 1. The invention also relates to a ventilation, heating and / or air conditioning device for a motor vehicle (not shown) equipped with the blower fitted with the control device 1.
Le dispositif de ventilation, de chauffage et/ou de climatisation permet de réguler la température d’un flux d’air à destination de l’habitacle du véhicule. The ventilation, heating and / or air conditioning device makes it possible to regulate the temperature of an air flow intended for the passenger compartment of the vehicle.
Le pulseur permet de faire pénétrer et de mettre en circulation l’air dans le dispositif de ventilation, chauffage et /ou climatisation. Dispositif de commande The blower allows air to enter and circulate in the ventilation, heating and / or air conditioning system. Control device
Comme visible sur la figure 1 , le dispositif de commande 1 comprend une carte de circuit imprimé 2. Comme il ressort également de la figure 1 , la carte de circuit imprimé 2 est délimitée par deux faces parallèles 3, 3’ sur lesquelles sont montées des composants électroniques 4. As shown in FIG. 1, the control device 1 comprises a printed circuit board 2. As also appears from FIG. 1, the printed circuit board 2 is delimited by two parallel faces 3, 3 ′ on which electronic components 4 are mounted.
La carte de circuit imprimé 2 comprend en particulier un composant électronique, référencé 4L, qui est une bobine anti-parasite sur le mode de réalisation illustré. The printed circuit board 2 comprises in particular an electronic component, referenced 4L, which is an anti-interference coil in the illustrated embodiment.
La bobine 4L est un dipôle comportant deux pattes 5, 6 de connexion électrique. The coil 4L is a dipole comprising two tabs 5, 6 for electrical connection.
Comme particulièrement visible sur la figure 1 , la patte 5 est montée sur la face 3 de la carte de circuit imprimé 2. Plus précisément, la patte 5 est brasée sur la surface de la carte de circuit imprimé 2. La patte 6 est montée traversante de la carte de circuit imprimé 2, la carte 2 comprenant un orifice traversant 7 pour le passage de la patte 6. As particularly visible in FIG. 1, the tab 5 is mounted on the face 3 of the printed circuit board 2. More specifically, the tab 5 is soldered on the surface of the printed circuit board 2. The tab 6 is mounted through of the printed circuit board 2, the card 2 comprising a through hole 7 for the passage of the tab 6.
La configuration traversante de la patte 6 permet d’éviter de recourir à un connecteur entre le moteur électrique et le dispositif de commande 1 , comme il sera expliqué ultérieurement. Les dimensions de l’orifice 7 et de la patte 6 sont choisies de sorte qu’il existe un jeu entre les parois de l’orifice 7 et la patte 6. The through configuration of the tab 6 makes it possible to avoid having to use a connector between the electric motor and the control device 1, as will be explained later. The dimensions of the orifice 7 and of the tab 6 are chosen so that there is a clearance between the walls of the orifice 7 and the tab 6.
Le jeu entre la surface de la patte 6 et les parois de l’orifice 7 est compris entre 1 ,5 millimètre et 2,5 millimètres. Cette plage de valeurs du jeu est particulièrement adaptée pour une bobine d’inductance d’un diamètre d’environ 10 millimètres. L’insertion de la patte 6 dans la carte de circuit imprimé 2 est ainsi grandement facilitée, même lorsque l’angle entre la patte 5 et la patte 6 du composant ne mesure pas exactement 90°.  The clearance between the surface of the tab 6 and the walls of the orifice 7 is between 1.5 millimeters and 2.5 millimeters. This range of clearance values is particularly suitable for an inductor with a diameter of about 10 millimeters. The insertion of the tab 6 into the printed circuit board 2 is thus greatly facilitated, even when the angle between the tab 5 and the tab 6 of the component does not measure exactly 90 °.
Le jeu est de préférence choisi pour que la patte 6 s’étende orthogonalement aux faces 3 et 4, avec un écart de ±2°. L’orifice 7 permet une protection de la patte 6, ce qui évite que la patte 6 casse, même en cas d’un déplacement inopportun du dispositif de commande 1. The clearance is preferably chosen so that the tab 6 extends orthogonally to the faces 3 and 4, with a deviation of ± 2 °. The orifice 7 allows protection of the tab 6, which prevents the tab 6 from breaking, even in the event of an untimely movement of the control device 1.
Sur la figure 1 , une extrémité 8 de la patte 6 est libre tandis qu’une extrémité opposée 9 est solidaire d’un corps 10 de la bobine 4L. Sur la figure 3, la bobine 4L est reliée électriquement à un balai 1 1 du moteur électrique. In Figure 1, one end 8 of the tab 6 is free while an opposite end 9 is secured to a body 10 of the coil 4L. In Figure 3, the coil 4L is electrically connected to a brush 1 1 of the electric motor.
La liaison électrique 12 entre l’extrémité 8 et le balai 1 1 comprend un fil tressé. The electrical connection 12 between the end 8 and the brush 1 1 comprises a braided wire.
De préférence, le fil tressé est serti à l’une de ses extrémités à la patte 6 et à l’autre de ses extrémités au balai 1 1. Preferably, the braided wire is crimped at one of its ends to the tab 6 and at the other of its ends to the brush 11.
Avantages Advantages
Le sertissage du fil tressé assure directement, de façon fiable et à moindre coût la liaison électrique entre le dispositif de commande 1 et le moteur électrique, ce qui permet de supprimer tout connecteur de puissance moteur. La configuration selon la présente invention permet également d’intégrer le dispositif de commande 1 sur le moteur, ce qui rend la liaison électrique plus courte et rend l’ensemble moins encombrant. The crimping of the braided wire directly, reliably and inexpensively ensures the electrical connection between the control device 1 and the electric motor, which makes it possible to eliminate any motor power connector. The configuration according to the present invention also makes it possible to integrate the control device 1 on the motor, which makes the electrical connection shorter and makes the assembly less bulky.
Grâce à la configuration selon la présente invention, les éléments anti-parasite (la bobine 4L) sont directement intégrés dans le dispositif de commande 1 , et leur assemblage ne nécessite pas de soudure à la vague, contrairement à l’état de l’art. Thanks to the configuration according to the present invention, the anti-parasite elements (the 4L coil) are directly integrated into the control device 1, and their assembly does not require wave soldering, unlike the state of the art .
Variantes de réalisation Variants of realization
L’invention ne se limite bien entendu pas au mode de réalisation illustré aux figures The invention is of course not limited to the embodiment illustrated in the figures
1 à 3. 1 to 3.
Notamment, selon la variante des figures 4 et 5, la carte de circuit imprimé 2 est munie d’une encoche T.  In particular, according to the variant of Figures 4 and 5, the printed circuit board 2 is provided with a notch T.
Comme particulièrement visible sur la figure 5, l’encoche T comprend une entrée 15 de passage de la patte 6, la patte 6 étant maintenue contre la paroi 16 de l’encoche As particularly visible in FIG. 5, the notch T comprises an inlet 15 for passage of the tab 6, the tab 6 being held against the wall 16 of the notch
7’. 7 ’.
Par ailleurs, le composant électronique traversant peut être un autre type de dipôle ou de multipôle, tel qu’un condensateur ou une résistance ou un transistor ou une diode.  Furthermore, the through electronic component can be another type of dipole or multipole, such as a capacitor or a resistor or a transistor or a diode.
De plus, l’orifice 7 et l’encoche T peuvent présenter différents types de section, notamment circulaire ou oblongue ou rectangulaire ou carrée. In addition, the orifice 7 and the notch T may have different types of section, in particular circular or oblong or rectangular or square.
