Description

La présente invention concerne un système de fixation d'un boîtier d'extrémité en matière plastique sur une culasse en matériau métallique d'un moteur électrique d'activation d'un organe fonctionnel de véhicule automobile. The present invention relates to a system for attaching a plastic end housing to a cylinder head made of metallic material of an electric motor for activating a functional member of a motor vehicle.

De tels moteurs électriques sont utilisés dans les véhicules automobiles pour activer par exemple différents organes de ceux-ci, tels que les vitres, les sièges ou encore les toits ouvrants. Such electric motors are used in motor vehicles to activate, for example, various members thereof, such as windows, seats or even sunroofs.

D'une façon générale, un tel moteur comporte une culasse en matériau métallique à au moins l'une des extrémités duquel est prévu un boîtier de sortie en matière plastique. In general, such an engine comprises a cylinder head made of metallic material at at least one of the ends of which an outlet box made of plastic is provided.

Un tel boîtier peut par exemple comporter un mécanisme de réduction muni d'une roue et d'une vis sans fin. Such a case can for example include a reduction mechanism provided with a wheel and a worm.

La fixation du boîtier sur la culasse est actuellement réalisée de deux façons, qui sont l'une par des moyens de vissage du boîtier contre la culasse et l'autre, par des moyens d'agrafage de ce boîtier sur cette culasse. The attachment of the housing to the cylinder head is currently carried out in two ways, which are one by means of screwing the housing against the cylinder head and the other, by means of stapling of this housing on this cylinder head.

Dans le cas de l'utilisation de moyens d'agrafage, des pattes, par exemple de la culasse, sont déformées pour s'engager dans des portions en creux du boîtier afin d'assurer cette fixation. In the case of the use of stapling means, lugs, for example of the cylinder head, are deformed to engage in hollow portions of the housing in order to ensure this fixing.

On conçoit cependant que ceci présente un certain nombre d'inconvénients, au niveau du temps requis pour ces opérations, des pièces nécessaires, mais également du fait qu'il convient de prévoir des moyens complémentaires de guidage en position du boîtier par rapport à la culasse afin de faciliter cette fixation. It is understood, however, that this presents a certain number of drawbacks, in terms of the time required for these operations, of the parts required, but also of the fact that it is necessary to provide additional means for guiding the position of the housing relative to the cylinder head. to facilitate this fixation.

Le but de l'invention est donc de résoudre ces problèmes. The object of the invention is therefore to solve these problems.

A cet effet, l'invention a pour objet un système de fixation d'un boîtier d'extrémité en matière plastique sur une culasse en matériau métallique d'un moteur électrique d'activation d'un organe fonctionnel de véhicule automobile, caractérisé en ce que le boîtier comporte des parties en saillie adaptées pour s'engager dans des évidements correspondants de la culasse et pour être serties à chaud autour de ceux-ci afin de fixer le boîtier sur la culasse.  To this end, the subject of the invention is a system for fixing an end box of plastic material on a cylinder head made of metallic material of an electric motor for activating a functional member of a motor vehicle, characterized in that that the housing has projecting parts adapted to engage in corresponding recesses of the cylinder head and to be hot crimped around them in order to fix the housing on the cylinder head.

L'invention sera mieux comprise à l'aide de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels
- la Fig.l représente une vue schématique de côté d'un exemple de réalisation d'un système de fixation selon l'invention; et
- la Fig.2 représente une vue de détail illustrant une partie en saillie d'un boîtier sertie autour d'un évidement correspondant d'une culasse, dans un système de fixation selon l'invention.The invention will be better understood with the aid of the description which follows, given solely by way of example and made with reference to the appended drawings, in which
- Fig.l shows a schematic side view of an embodiment of a fixing system according to the invention; and
- Fig.2 shows a detail view illustrating a projecting part of a housing crimped around a corresponding recess of a cylinder head, in a fixing system according to the invention.

On reconnaît en effet sur ces figures, un ensemble de moteur électrique d'activation d'un organe fonctionnel de véhicule automobile, désigné par la référence générale 1. We recognize in these figures, an assembly of electric motor for activating a functional member of a motor vehicle, designated by the general reference 1.

De façon classique, un tel ensemble de moteur comporte une culasse désignée par la référence générale 2, réalisée en matériau métallique et à au moins l'une des extrémités de laquelle est prévu un boîtier en matière plastique désigné par la référence générale 3. Conventionally, such an engine assembly comprises a cylinder head designated by the general reference 2, made of metallic material and at at least one of the ends of which is provided a plastic casing designated by the general reference 3.

Des moyens de fixation complémentaires désignés par la référence générale 4 sont prévus en regard les uns des autres sur cette culasse et sur ce boîtier. Additional fixing means designated by the general reference 4 are provided opposite each other on this cylinder head and on this housing.

Selon l'invention, la fixation du boîtier sur la culasse est assurée par l'intermédiaire de parties en saillie du boîtier venues de matière avec celui-ci et dont deux, 5 et 6, sont représentées sur cette figure et qui sont adaptées pour s'engager dans des évidements correspondants 7 et 8 de la culasse 2, et plus particulièrement d'oreilles 9 et 10 de cette culasse, et pour être serties à chaud autour de ceux-ci afin d'assurer cette fixation du boîtier sur la culasse. According to the invention, the fixing of the housing to the cylinder head is ensured by means of projecting parts of the housing which are integrally formed therewith and of which two, 5 and 6, are shown in this figure and which are suitable for s 'Engage in corresponding recesses 7 and 8 of the cylinder head 2, and more particularly of ears 9 and 10 of this cylinder head, and to be crimped hot around them to ensure this fixing of the housing on the cylinder head.

Comme cela est représenté, ces parties en saillie 5 et 6 du boîtier s'étendent par exemple parallèlement à l'axe de l'ensemble de moteur et peuvent présenter des extrémités de section progressivement décroissante permettant de faciliter leur engagement dans les évidements correspondants de la culasse et donc le centrage du boîtier par rapport à cette culasse. As shown, these projecting parts 5 and 6 of the housing extend for example parallel to the axis of the motor assembly and may have ends of progressively decreasing section making it possible to facilitate their engagement in the corresponding recesses of the cylinder head and therefore the centering of the housing relative to this cylinder head.

On conçoit alors que lorsque ces parties en saillie 5 et 6 du boîtier sont engagées dans les évidements 7 et 8 de la culasse, il suffit de sertir celles-ci à chaud autour de ces évidements pour assurer la fixation du boîtier sur cette culasse comme cela est illustré sur la figure 2. It will therefore be understood that when these projecting parts 5 and 6 of the housing are engaged in the recesses 7 and 8 of the cylinder head, it suffices to crimp them hot around these recesses to ensure the fixing of the housing on this cylinder head like this is illustrated in figure 2.

Différents moyens de sertissage peuvent être utilisés pour réaliser cette opération et on citera à titre d'exemple des moyens de sertissage par voie ultrasonore de type classique. Different crimping means can be used to carry out this operation and an example will be crimping means by ultrasound of conventional type.

On conçoit alors que le système de fixation tel qu'il vient d'être décrit présente un certain nombre d'avantages par rapport aux systèmes de l'état de la technique dans la mesure où celui-ci est extrêmement simple, permet d'engager rapidement le boîtier sur la culasse et ne nécessite pas de pièces supplémentaires pour assurer le centrage du boîtier par rapport à la culasse et la fixation de ces organes. It can therefore be seen that the fastening system as just described has a certain number of advantages compared with the systems of the prior art insofar as this is extremely simple, makes it possible to engage quickly the housing on the cylinder head and does not require additional parts to ensure the centering of the housing relative to the cylinder head and the fixing of these members.

Il va de soi bien entendu que différentes formes de réalisation des parties en saillie de ce boîtier et des évidements correspondants de la culasse peuvent être envisagés, et que de tels moyens peuvent être répartis le long de la zone de jonction entre le boîtier et la culasse.  It goes without saying of course that different embodiments of the projecting parts of this housing and corresponding recesses of the cylinder head can be envisaged, and that such means can be distributed along the junction zone between the housing and the cylinder head .
