Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a bus comprising an electronic unit. The invention also relates to a method of installing said electronic unit in said bus.

On some types of vehicles, there is a need to monitor the operating conditions of the tires and possibly keep a history of the development of some characteristic operating parameters over time. For example, when considering vehicles using tires of the type of tire remaining safe after a puncture, i.e. tires capable of guaranteeing a ride of several kilometers of covered distance even in the case of lowering the tire, several characteristic parameters presented correspond, for example, to the maximum speed, temperature and the maximum distance that must be covered, the aforementioned requirement is especially relevant for the safe use of the mentioned type of tires.

The characteristic parameters that are usually considered can be an identification code, temperature, pressure, distance traveled by the tire, as well as parameters created from mathematical calculations that can be performed on the tire or on the dashboard of the vehicle.

For this purpose, an electronic unit can be installed in the bus, said electronic unit is designed to receive at least one of the aforementioned characteristic parameters. Preferably, the electronic unit may comprise at least one sensor, possibly associated with a control unit (such as a microprocessor) and / or a data storage unit. The electronic unit is preferably associated with the antenna, preferably said antenna has the task of permitting the exchange of an RF signal with devices mounted on a vehicle dashboard.

In addition, the antenna can enable the system present in the bus to appropriately power without using independent power supplies (e.g., batteries in the bus). Therefore, a device mounted on the dashboard of the vehicle is provided to generate an electromagnetic field with which the antenna placed on the bus can communicate by induction, and by which the necessary energy for the operation of the sensor and a possible control unit is delivered by the antenna itself.

US patent 5090237 proposes a pressure sensor for detecting air pressure of a car tire; the sensor has a housing extending into a recess formed in the wall of the tire rim, and an annular flange located on the housing and holding the spring on the side of the rim wall. A spring is provided for fixing part of the outer flange of the pressure sensor housing on the other side of the rim wall.

In this technological area, the applicant considers it necessary:

- improve the ease of production of the engaging housing used for engagement between the electronic unit and the bus;

- to guarantee significant mechanical isolation of the electronic unit from impacts generated along the unit itself from the tire during movement;

- provide the ability to work also in conditions of lack of pressure in the tire;

- provide the ability to easily use the above electronic unit in an already manufactured tire without affecting the operational characteristics of the tire itself (for example, gluing technologies used in tire restoration can be applied).

In addition, the applicant also considers it necessary to implement an engaging housing for the electronic unit, which allows integration into the tire during assembly on the rim.

The Applicant has found that by associating the electronic unit with the bus by means of a fixing body having two parts, the antenna is fitted into the groove of said parts to maintain communication between said parts and said electronic unit, significant production simplification can be achieved and improvements can be made both from the point of the reliability of engagement between the electronic unit and the bus, and from the point of view of the practical operation of the electronic unit itself.

In particular, according to a first aspect, the invention relates to a tire for vehicle wheels having an inner surface of a substantially toroidal shape, comprising:

- an electronic device containing an electronic unit and an antenna, the latter is connected to the said electronic unit and has an inner perimeter edge;

- a locking housing mounted on said inner surface for engagement between said electronic device and said bus, said locking housing comprises at least two parts, said electronic unit is placed between said parts, each of said parts has:

a mounting surface attached to the inner surface of said tire;

a groove into which the inner perimeter edge of said antenna is fitted in order to maintain communication between the electronic unit and the fixing body.

According to another aspect, the present invention relates to a method for mounting an electronic unit in a bus, said method comprising the steps of:

- providing a tire having an inner surface of substantially toroidal shape;

- providing a locking body comprising at least two parts, each of said parts has a mounting surface and a groove;

- providing an electronic device containing an electronic unit and an antenna, the latter is connected to the said electronic unit and has an inner perimeter edge;

- installation of the inner perimeter edge of said antenna in the groove of each of said parts to engage said electronic unit between said parts;

- fixing the mounting surfaces of said parts to the inner surface of said tire.

In a preferred embodiment, the locking body is attached to the tire sealing layer; in this case, preferably, the main longitudinal dimension of the electronic unit is transverse and, in particular, perpendicular to the equatorial plane of the tire.

In a further preferred embodiment, the locking body is attached to the sidewall of the tire; in this case, the main longitudinal dimension of the electronic unit is essentially parallel to the equatorial plane of the tire.

The structural solution of the latter embodiments is aimed at minimizing the effect of the deformation that the tire undergoes during operation on the electronic unit and on the connection between the locking body and the tire.

In another preferred embodiment, the parts of the retainer body are separate parts.

In particular, the two parts defining the locking body may be substantially identical to each other.

Thus, a simplification in production is achieved, since both parts can be realized through one form.

Additional features and advantages will become more apparent from a detailed description of a preferred, but not exclusive embodiment of a bus comprising an electronic unit, and a method of installing said electronic unit in said bus in accordance with the present invention. This description will be described later in this document with reference to the accompanying drawings, data for the purpose of non-limiting examples, in which:

With reference to the drawings, a tire for vehicle wheels in accordance with the present invention is generally indicated by 1.

Tire 1 can be mounted on any type of vehicle, such as cars or motorcycles; more specifically, bus 1 is preferably mounted to be used on vehicles that are equipped with a dashboard with the necessary electronic devices for working together and interacting with devices located on the bus itself and described subsequently.

Tire 1 (Fig. 1a, 1b) has an inner surface 2 of substantially toroidal shape; this inner surface 2 may comprise a layer of elastomeric material, which is substantially airtight and is commonly referred to as a “sealing layer”.

The electronic device 10 is mounted on the inner surface 2.

The electronic device 10 comprises an electronic unit 20 and an antenna 30 (FIGS. 2a-2b).

Preferably, the electronic unit 20 is installed to detect operating parameters related to the bus 1 and the operating conditions of the bus itself. In particular, the electronic unit 20 may include one or more sensors to detect said operating parameters, which, for example, may be tire temperature, internal pressure and / or distance traveled, possibly calculated in conjunction with devices located on the dashboard.

The electronic unit 20 may be associated with a microprocessor connected to said sensors to control their operation, and to a storage unit to store data detected by the sensors.

Preferably stored in the electronic unit 20 (in the storage unit, if present) are the bus identification data, which may provide the ability to specifically identify the bus during processing and evaluation of the operating parameters mentioned above.

Preferably, the electronic unit 20 is configured to "talk" with an electronic device located on the dashboard of the vehicle. To enable communication between the electronic unit 20 and the electronic device on the dashboard, an antenna 30 is provided, which should be operatively associated with the electronic unit 20.

In addition to the above, the antenna 30 can also be used to power the electronic unit 20 and devices associated therewith so as to avoid the use of independent power supplies in the bus 1.

Data is exchanged between the electronic unit 20 and said electronic device through the transmission and reception of radio frequency signals (RF signals), the frequency of which can be in the range between about 100 kHz and about 50 MHz and preferably can correspond to about 125 kHz. In particular, this frequency range can be used if the power supply of the electronic unit 20 should preferably occur through the antenna 30 itself, which in this case will have a “closed” type configuration. If, on the contrary, it is desired to use the antenna for data transmission / reception, frequencies in the range between approximately 300 MHz and approximately 2.5 GHz may also be used, in which case “open” type antennas are used.

In the present context, an “open” type antenna means an antenna whose configuration defines an electrically open circuit. For example, the antenna housing may have one or more ends electrically connected to the detection unit, and one or more “free” ends.

According to the formulation, an antenna with a “closed” type configuration means an antenna whose shape defines an electrically closed circuit, in which case the antenna body has two ends, which are both electrically connected to said detection unit. The interaction between the devices on the dashboard, the antenna 30 and the electronic unit 20, therefore, forms, when required, a detection system that enables the electronic unit 20 to also operate without the presence of batteries or similar power supplies installed inside the bus 1.

The antenna 30 has an inner perimeter edge 31 that is adapted to engage with the locking body, which will subsequently be opened.

Preferably, the antenna 30 has a substantially annular shape.

Preferably, the antenna 30 has two separate contact areas for connection to the electronic unit 20, i.e. the first contact region 31a and the second contact region 31b. In particular, the electronic unit 20 has an oblong shape elongated along the main longitudinal direction D from the first to the second contact region 31a, 31b of said antenna 30 (Figs. 3a-3c, 4a-4c).

In a preferred embodiment, the electronic unit 20 has a substantially prismatic shape and preferably has a parallelepiped shape.

In the case where the antenna 30 has an annular shape, and, in particular, a substantially circular shape, the first and second contact areas 31a, 31b may be diametrically opposed, so that the electronic unit 20 is located along the diameter of said annular shape.

In a preferred embodiment, the antenna 30 comprises a first open type auxiliary antenna and a second closed type auxiliary antenna.

The first auxiliary antenna can operate at 433 MHz, for example, to exchange data with an electronic device located on the dashboard of the vehicle.

The second auxiliary antenna can operate at a frequency of 125 kHz, for example, both to power the electronic unit 20 and to exchange data with the said electronic device.

Preferably, the antenna 30 further comprises an annular support for receiving said first and second auxiliary antennas.

In particular, said annular support may surround the locking body 40.

For mounting the electronic device 10 in the tire 1, a fixing body 40 is provided, which is mounted on the inner surface 2 of said tire 1.

The locking body 40 comprises at least two parts 41; each part 41 has a mounting surface 42 attached to the inner surface 2 of the tire 1, and a groove 43 into which the inner perimeter edge 31 of the antenna 30 is fitted.

The electronic unit 20 is placed between the two parts 41, so that the engagement between the inner perimeter edge 31 of the antenna 30 and the groove 43 of each part 41 provides a restriction of movement between the electronic unit 20 and the locking body 40.

Each part 41 preferably has a holding part 44 having an upper surface 45 facing the front of the mounting surface 42; in a preferred embodiment, a groove 43 is formed between the mounting surface 42 and the holding portion 44.

Preferably, the holding portion 44 of each portion 41 has a recess 44a to allow elastic deformation of the holding portion 44 and subsequent engagement between the antenna 30 and the grooves 43.

In other words, the holding portion 44 can elastically deform so that the same holding portion 44 can be inserted between the electronic unit 20 and the inner perimeter edge 31 of the antenna 30, thereby obtaining a travel restriction between the electronic unit 20 and the fixing body 40.

Preferably, each recess 44a faces the respective side wall of the electronic unit 20.

Advantageously, each part 41 has a first side surface 46 on which a groove 43 is formed, and a second side surface 47, which is in contact with the electronic unit 20.

In more detail, the second side surfaces 47 of the parts 41 are mutually facing each other with their faces to engage the electronic unit 20.

Preferably, the second side surfaces 47 of the parts 41 are substantially parallel to each other.

Preferably, the parts 41 are substantially identical to each other.

Preferably, the electronic unit 20 has a pair of side walls 21 substantially parallel to the main longitudinal direction D; each side wall 21 is at least partially in contact with a corresponding second side surface 47 of said portions 41.

It should be noted that the parts 41 of the locking body 40 are not in contact with each other, so that a significant mechanical isolation of the electronic unit 20 from the effects generated on the same electronic unit 20 by the bus 1 during operation is achieved.

In addition, preserving the preset distance between the two parts 41, the correct operation of the electronic unit 20 is allowed, since the sensors and / or transmitting and receiving devices provided therein are not covered by the material from which the parts 41 are made (for example, elastomeric material).

Preferably, each part 41 has a substantially semi-cylindrical shape; therefore, the locking body 40 has a substantially cylindrical shape.

In this case, the mounting surfaces 42 of the parts 41 define the base of said cylindrical shape.

Each part 41 of the locking body 40 may have a pointed end 48 in contact with the inner surface 2 of the tire 1 and deviating from said inner surface 2; in particular, the angle α defined between the mounting surface 42 of part 41 and the outer inclined side wall of the pointed end 48 is preferably in the range between 25 ° and 60 °, and more preferably between about 40 ° and about 50 °.

It should be noted that in the description and in the following claims for “diameter”, when the circle is not referred to, the maximum total dimension, measured in a plane substantially parallel to the contact surface between the inner surface 2 of the tire 1 and the locking body 40, is meant.

Preferably, the diameter of the upper part of the locking body 40, i.e. the part defined by the holding parts 44 covers a range between 26 mm and 40 mm and, in particular, covers a range between 32 mm and 36 mm.

Preferably, the diameter of the groove 43 covers a range between 20 mm and 35 mm and, in particular, covers a range between 23 mm and 30 mm.

Preferably, the diameter of the locking body 40 in the area of contact with the inner surface 2 of the tire 1 covers a range between 31 mm and 45 mm and, in particular, covers a range between 36 and 40 mm.

Preferably, the ratio between the height of the fixing housing 40 and the height of the electronic unit 20, both are measured in a direction perpendicular to the mounting surface 42 and / or to the upper surface 45, greater than 1.

In the first embodiment, schematically shown in FIG. 1a, the electronic unit 20 is mounted on the inner surface 2 (for example, on the sealing layer 2a) of the tire 1 and is preferably located on the equatorial plane E of the same tire 1; the main longitudinal direction D of the electronic unit 20 is transverse and, in particular, perpendicular to the equatorial plane E.

In a second embodiment, schematically shown in FIG. 1b, an electronic unit 20 is mounted on a side wall 2b of a bus 1; the main longitudinal direction D of the electronic unit 20 is substantially parallel to the equatorial plane E.

Preferably, the parts 41 are made of an elastomeric material selected, for example, from synthetic diene rubbers, natural rubber, ethylene-propylene rubber, ethylene-propylene-diene rubber, and the like.

More specifically, said elastomeric material has a hardness in the range between about 28 ° on the Shore A scale and about 75 ° on the Shore A scale (at 23 ° C), and preferably between about 36 ° on the Shore A scale and about 50 ° on the scale Shore A (at a temperature of 23 ° C).

In a preferred embodiment (FIG. 2a), the parts 41 are separated from each other.

In this case, the mounting surface 42 of the parts 41 may be in direct contact with the inner surface 2 of the tire 1.

In another preferred embodiment (FIG. 2b), the locking body 40 further comprises a connection layer 40a to which the mounting surfaces 42 of the parts 41 are connected.

Parts 41 may be mounted on said connection layer 40a; alternatively, portions 41 may be manufactured as an integral part of said bonding layer 40a.

Preferably, the joint layer 40a is made of an elastomeric material; the latter can be selected, for example, from synthetic diene rubbers, natural rubber, ethylene-propylene rubber, ethylene-propylene-diene rubber, and the like.

In particular, the connection layer 40a may be made of the same material as the parts 41.

In the case where a connection layer 40a is provided, the parts 41 of the fixing body 40 are not directly in contact with the inner surface 2 of the tire 1, the same connection layer 40a is inserted between the parts 41 and the inner surface 2.

It should be noted that in both embodiments (individual parts and parts connected by the connection layer 40a), a satisfactory mechanical isolation between the parts 41 is achieved, and the deformations to which the tire 1 is subjected during movement are not significantly transmitted to the electronic unit 20.

When the electronic unit 20 is to be installed in the bus 1, the parts 41 are arranged so that the second side surfaces 47 face each other.

Preferably, at this stage, the second side surfaces 47 are parallel to each other.

Parts 41 are not in contact with each other; in particular, the parts 41 are arranged so that the distance X between the second side surfaces 47 is substantially equal to the size of the electronic unit 20, measured in a direction transverse and preferably perpendicular to the main longitudinal direction D.

In practice, such a dimension is measured in a direction substantially perpendicular to the second side surfaces 47 of the parts 41; indeed, in a preferred embodiment, the second side surfaces 47 are substantially parallel to the main longitudinal direction D of the electronic unit 20 when the electronic device 10 and the fixing body 40 are assembled.

The electronic unit 20 is then inserted between the parts 41 and, in particular, between the second side surfaces 47; preferably, the insertion direction is substantially perpendicular to the mounting surfaces 42 of the parts 41.

In other words, the step of inserting the electronic unit 20 between the second side surfaces 47 comprises moving relative to each other of the fixing body 40 and the electronic device 10 in a direction substantially perpendicular to the mounting surfaces 42.

In more detail, before moving the locking body 40 and the electronic device 10 to each other, the electronic device 10 is closer to the upper surface 45 than to the mounting surface 42 of each part 41.

The electronic device 10 has a vertical axis passing through the center of gravity of the same electronic device 10 and essentially perpendicular to the plane in which the antenna 30 lies.

The locking body 40 has a vertical axis extending through the center of gravity of the same locking body 40 and substantially perpendicular to the mounting surfaces 42 of the parts 41.

Preferably, during the insertion step of the electronic unit 20 between the parts 41, the vertical axis of the electronic device 10 and the fixing body 40 essentially coincide.

Preferably, during the insertion step of the electronic unit 20 between the parts 41, the antenna 30 is inserted into the grooves 43 of the parts 41, so that the second side surfaces 47 are supported in contact with the electronic unit 20, and the electronic device 10 is thus engaged with the locking body 40. Preferably , during the step of fitting the inner perimeter edge 31 of the antenna 30 into the groove 43 of each part 41, the vertical axis of the electronic device 10 and the fixing body 40 essentially coincide.

The insertion of the electronic unit 20 between the second side surfaces 47 and the insertion of the antenna 30 into the grooves 43 are achieved by elastic deformation of the holding parts 44 of each part 41.

As disclosed above, the parts 41 may be separate parts.

Alternatively, the parts 41 may be connected by a connection layer 40a; in this case, the method according to the invention may include the step of installing the parts 41 on the connection layer 40a.

It should be noted that the installation step of the parts 41 on the connection layer 40a is not performed when the parts 41 are made as an integral part of the connection layer 40a.

Then, the assembly defined by the electronic device 10 and the fixing body 40 is mounted on the inner surface 2 of the tire 1.

In particular, the fastening surfaces 42 of the parts 41 are attached to said inner surface 2, for example by means of suitable adhesive material.

In other conditions, the locking body 40 is manufactured separately from the tire 1 and then attached to the inner surface 2 of the same tire 1.

In the case where the parts 41 are separate parts, the adhesive material is directly applied between the parts 41 and the inner surface 2 of the tire 1, whereas if a bonding layer 40a is provided, such an adhesive material is preferably applied between the bonding layer 40a and the inner surface 2.
