    [0001] FIELD OF APPLICATION OF THE INVENTION The present invention relates to the field of the detection of parameters inside the wheels of a vehicle and in particular to the adaptations for fixing a detection box inside a wheel and more particularly to the inner wall of the tire of the wheel. DESCRIPTION OF THE PRIOR ART There are a plurality of electronic package fastening solutions containing the parameter measuring sensors such as temperature and pressure inside a tire of a wheel. One solution is to attach the housing to the inner walls of the tire as described in FR2899150, DE102007010782, WO2004 / 002758 and WO2011 / 060850.
    [0002] Such a solution nevertheless has several drawbacks, including the following: the proximity of the casing to the tread of the tire subjects it to the same shocks, temperature changes and deformations (such as folding) as those under a wide spectrum of frequencies by the tire, - the heat exchange of this proximity is harmful to the service life of the electronic box and its components, - the centrifugal force tends to keep the sensor in position but also to point out any material contained in the tire tending to obstruct the orifices of the sensor or sensors, - when the centrifugal force does not sufficiently maintain the housing, it can be ejected from the housing in which it was placed for example during the passage of the tire on a 35 sidewalk angle at low speed. More recently, the Applicant has described in EP 2641756, a device for fixing a measuring case on the inner wall of a tire remarkable in that it comprises at least one interposed spacer element. between the housing and said inner wall so as to create a space between the housing and said inner wall. This space made it possible to create an intermediate zone avoiding or attenuating the transmission of shocks and heat. In addition, it gave the possibility to orient the housing so that the measuring port giving access to the sensor is open between said housing and the inner face of the tread of the tire so that the material contained in the The pneumatic force projected by the centrifugal force does not obstruct the orifices of the sensor or sensors. The Applicant has nevertheless found that the fixing at the origin of the spacer could be improved. DESCRIPTION OF THE INVENTION The Applicant has therefore conducted research aimed at improving the attachment of an electronic measuring unit while retaining the advantages of a good orientation of the case. This research led to the design and manufacture of a device for fixing the internal wall of a tire of an electronic parameter measurement unit inside the tire, said box being preformed with an orifice. communicating its interior volume with the inner volume of the tire, the device associating said housing to a flexible receptacle which is fixed to said inner wall by an adhesion means 25 is preformed to receive and retain said housing. According to the invention, the device is remarkable in that said flexible receptacle forms a compartment equipped with an opening, through which said housing is introduced and which is bordered by an externally extending rim and proposing a contact surface for the means of adhesion, so that once the receptacle fixed, said opening is closed by the inner wall on which the receptacle is fixed. This feature is particularly advantageous in that it provides a receptacle which must accommodate the housing before fixing and whose opening is closed by the wall on which the receptacle is sticking. There is then no risk of ejection of the housing in accordance with the objectives of the invention.
    [0003] According to a preferred embodiment, the receptacle is made of an elastic flexible material such as rubber. The housing is placed by stretching the periphery of the opening. The casing is then maintained, it is in slight compression and is not in direct contact with the tire. This receptacle is sufficiently deformable to prevent the shocks and stresses to which the tire is subjected are transmitted to the housing and the sensor it contains. The adhesion means may be mechanical, chemical or molecular. According to another particularly advantageous feature, said opening is equipped with another so-called internal rim flange which, extending internally, creates a narrowing for retaining the housing in said compartment and a bracing defining a space between the housing and the housing. internal wall of the tire. This space avoids direct contact of the housing against the inner wall which allows to isolate said housing on the one hand and preserve the inner waterproof layer of the tire on the other. In addition, said housing is oriented in said compartment so that its opening opens on said space. Thus, the orifice in the housing is not subjected to projections that the centrifugal force is likely to create and is itself protected by the walls of the compartment. This orientation of the housing nevertheless requires features to enable the measurement to be made under good conditions. Thus, to do this, according to another characteristic, the walls of the compartment are pierced by at least one hole. According to a preferred embodiment, said walls are pierced by a plurality of holes. Said housing is itself preformed with at least one projection co-operating with said hole by being housed therein in order to reduce the surface area of the contact points between the housing and the compartment and to prevent the thermal or physical stresses transmitted by the 35 pneumatic compartment do not refer to the housing. Thus, although the receptacle is deformable, its internal walls are fitted to the body of the housing and cooperate by means of this connection projections / holes.
    [0004] According to a preferred embodiment, said housing is preformed with a plurality of projections cooperating with a plurality of holes drilled in said walls of the compartment. Indirectly subjected to stresses and shocks, the housing will move and evacuate the shock energy kinetically and then transfer this energy to the receptacle whose flexible elastic nature ensures the dispersion of the initial energy shock. This connection makes it possible to reduce the movements of the casing while allowing the passage of air for the measurement of the pressure and the temperature of the tire. These holes have other functions to allow the water or other liquid soaps to escape from the receptacle and not to remain accumulated by capillarity on the orifice which is formed the housing for pressure taking.
    [0005] According to another particularly advantageous characteristic, said housing is preformed with projections bearing on the internal rim of the opening of the compartment. These projections reduce the surface of the contact points and create a gap between the surface of the inner flange and the surface of the housing, where air can circulate. To facilitate this circulation, said housing and / or said receptacle are preformed with passages communicating the space created inside the compartment, and the inside of the tire both to allow good measurement but also to facilitate the 'evacuation. According to a particularly advantageous characteristic, said housing is preformed externally grooves in which communicates said preformed orifice in the housing. The walls of the compartment are preformed with orifices communicating with said grooves ensuring that the orifice of the housing communicates with the internal volume of the tire. In addition, these throats and these holes coming in correspondence will facilitate the evacuation of any material likely to be introduced between the housing and said inner wall. The air circulation function is thus associated with the evacuation function out of the compartment of the fluids trapped in the tire, such as water, mounting soap, puncture-resistant liquid, etc.
    [0006] Said housing and said receptacle adopt an oblong shape and are arranged on the inner wall of the tread of the tire so that the greatest length is positioned over the width of the tire. Such an arrangement 5 also contributes to the protection of the housing and the receptacle against the deformations experienced by the tire. In addition, such a shape avoids any aggression of the inner walls of the receptacle by providing a volume without protruding ridges. According to another particularly advantageous characteristic, the casing is made by overmolding its components in a resin thus allowing the realization of the same shape while allowing overmolding of different types of components such as batteries that may differ according to the customer's needs . Since the basic concepts of the invention have been set forth above in their most basic form, other details and features will become more apparent upon reading the description which follows and with reference to the accompanying drawings, given by way of example. non-limiting example, an embodiment of a device according to the invention.

According to another non-limiting embodiment, the receptacle is glued (as for cold vulcanization). According to another non-limiting embodiment, the adhesion means consists of a microsuction attachment module 20 preformed in the receptacle or disposed between the receptacle and the tire wall. Said housing 100 and said receptacle 200 adopt an oblong shape and are arranged on the inner wall of the tread of the tire so that the greatest length 25 is disposed in the width of the tire P so that during training of a fold on the tire, the housing is only slightly subjected to a bending force. As illustrated by the drawings of FIGS. 3, 4 and 5, said flexible receptacle 200 forms a receiving compartment 210 equipped with an opening 220, through which said housing 100 is inserted and which is bordered by a peripheral rim 221. extending externally and providing a contact surface 222 with the gluing means 300 so that once the receptacle is glued, said opening 220 is closed by the inner wall of the tire P on which the receptacle 200 is glued. Said opening 220 is equipped with an additional rim 223 extending internally peripherally, creating a shrinkage by decreasing the opening, for purposes not only of retaining the housing in said compartment but also of a bracing creating A space E between the housing 100 and the inner wall of the tire P. According to the preferred embodiment illustrated, the outer and inner flanges 221 and 223 are preformed in the receptacle 200 in an extension of one another.

The upper wall of the compartment 210 is pierced with a plurality of circular holes 211 in which are introduced vertical cylindrical projections 120 preformed on the upper face of the housing 100 for purposes retaining portions as illustrated in the drawings of FIGS. 3, 6 and 7. Said housing is further preformed on the periphery of its lower face with other cylindrical vertical projections 130 bearing on the internal rim 223 of the opening 220 of the 210. Thus, the housing 100 is in contact with the surface of the receptacle 200 bonded to the tire by means of the ends of these projections. s 130. They also allow the air to circulate in the space E, circulation illustrated by the arrows F.
    [0008] As illustrated, to facilitate this circulation (arrow F), the underside of said housing 100 is preformed with grooves 140 arranged at right angles and communicating with the orifice 110 (the cutting plane has been modified to admit the orifice). . These grooves 140 extend on the sides of said housing 100 and communicate with orifices 212 made for this purpose in the walls of the compartment 210. According to a non-illustrated embodiment, the housing 100 is preformed so that the grooves 140 is cross at the orifice 110. According to a preferred embodiment but not limiting, the housing 100 is entirely overmolded in a hot-melt type resin. According to a preferred embodiment but not limited to, this housing has a Shore A hardness ranging from 60 to 80 and the receptacle has a Shore A hardness ranging from 45 to 60.
    [0009] The maintenance of the housing can be achieved by tearing the wall of the compartment. According to another embodiment not illustrated, said receptacle 200 is equipped with an upper opening controlled by a Velcro that simply control to release the housing 100. It is understood that the device, which has just been above described and shown, has been for disclosure rather than limitation. Of course, various arrangements, modifications and improvements may be made to the example above, without departing from the scope of the invention. 15 20 25 30 35
