Description
"LIQUID FLUID LEVEL METERING DEVICE IN CONFINED ENVIRONMENT"
Field of the Invention
[01 ] The invention in question refers to a fluid metering device in a confined environment and, more particularly, a fuel level metering device in a fuel tank of an automotive vehicle or similar.
[02] Considering that said liquid fluid level metering device in confined environment is especially based on magnetic sensing, therefore, in sensing without mechanical contact, the invention in question generally refers to the technological field of the means for indicating or metering the liquid level, according to class G01 F 23/00 of the International Patent Classification and, in a more specific manner, the present invention refers to the technological field of liquid level indication or metering devices using magnetically driven indicating means, according to class G01 F 23/38 of the International Patent Classification.
Fundamentals of the Invention
[03] As is well known to those skilled in the art, the present state of the art comprises certain types of magnetic sensors. Variable Magnetic Reluctance sensors, Hall Effect sensors and Magneto-resistive sensors are only three examples of this type of sensor.
[04] However, the Hall Effect sensor is of particular interest to the present invention, which is normally constituted by a static small chip of semiconductor material, a movable magnet and an electronic circuit which includes an electric power supply and an electrical quantity meter (voltmeter and/or ammeter). According to knowledge consolidated by the state of the art, the functional principle of this type of sensor lies in the fact that the electrical resistance of the chip is sensitive to the presence of the magnetic field of the magnet, wherein the variation of the proximity of the magnet in relation to the chip generates variation in the electrical resistance of the latter and,
consequently, it generates variation in the electric current of the electronic circuit, which sensor converts the variations of current into voltage changes, wherein the voltage output of the sensor can be analog or digital.
[05] Among the many possible applications of a Hall Effect sensor (speed sensor, position sensor and proximity sensor, for example) stands out the application in fuel level metering systems in fuel tank of self- propelled vehicle, as described in the patent documents US 7,093,485 and BRPI 09030379.
[06] In general terms, among other technical aspects not necessarily relevant to the context in question, the patent document US 7,093,485 describes a (Hall Effect) sensor of level especially suited to the installation emerged in a fuel tank. It is thus verified that its static body (body that sustains and accommodates the components which make part of the sensor, except the magnet, and its electrical contacts) comprises a simple closing structure, with unified contouring protection for the electrical contacts. The drawbacks of this assembly are widely explored in the aforementioned patent document BRPI 09030379, which is fully incorporated herein by reference.
[07] The abovementioned and previously cited patent document BRPI 09030379 describes, among other technical aspects not necessarily relevant to the context in question, a (Hall Effect) sensor of level especially suited to the installation submerged in a fuel tank. It is thus verified that its static body (body that sustains and accommodates the components which make part of the sensor, except the magnet, and its electrical contacts) comprises a housing case and a modular cover, said modular cover being designed to close the opening of the housing case through which the components that make part of the sensor, except the magnet, and its electrical contacts are inserted. Said housing case defines individualized contouring protection for the electrical contacts.
[08] Although the fitting connection between the housing case and the modular cover can be optimized to exhaustion (with the application of more efficient sealing joint, for example), it is verified that it will always be subject to possible mounting defects and corrosion degradation due to the chemical properties of the fuel (mainly, due to the chemical properties of fuels with high percentage of ethanol).
[09] Thus, according to the known state of the art, it is verified the absence of fluid metering devices in confined environment whose static body comprises a totally hermetic assembly. Obviously, this current scenario is temerarious, after all, the risks and problems related to the exposure of the internal components of the sensor to the fuel in the storage tank are well known.
[010] In addition, it is also verified that none of the solutions described in the patent documents US 7,093,485 and BRPI 09030379, in addition to the other solutions which make part of the current state of the art, comprise efficient means of limiting or annulling the movement of the internal components of the sensor within the static body. This means that certain vibrations subjected to the self-propelled vehicle are, even minimally, subjected to the said internal components of the sensor, which may collide with the walls of the static body and, consequently, present a reduced service life.
[01 1 ] It is from this scenario that the present invention arises.
Objectives of the Invention
[012] Based on the context previously presented, it is the principal objective of the invention in question presenting a liquid fluid level metering device in confined environment which, especially suited to the installation submerged in a fuel tank, comprises a static body.
[013] Accordingly, it is one of the objects of the present invention that the static body of the liquid fluid level metering device exhibits high resistance to the corrosion due to the chemical properties of the fuel into which it will be submerged.
[014] It is also one object of the invention to avoid contact between the internal components of the sensor and the fuel in which the static body will be submerged.
[015] It is still another object of the invention in question that the assembly of the liquid fluid level metering device in an environment eliminates the possibility of movement of the internal components of the sensor within the static body.
Brief Description of the Invention
[016] The aforementioned objectives are fully achieved by means of the liquid fluid level metering device in confined environment, which comprises a static body and a movable body hingedly fastened to the static body. Said static body is composed of at least one magnetic sensor and at least one conducting assembly (2), and said movable body is composed of at least one magnet.
[017] According to the invention in question, said liquid fluid level metering device in confined environment further comprises at least one housing body provided with at least one housing cavity, so that the magnetic sensor is integrally disposed within the at least one housing cavity of said housing body, and the conducting assembly is at least partially disposed within the at least one housing cavity of said housing body.
[018] In general terms, the volume of said at least one housing cavity of the housing body is filled by at least a thermoset polymer so as to encapsulate, at least partially, the magnetic sensor and the conducting assembly.
[019] Preferably, the liquid fluid level metering device in confined environment further comprises at least one outer body, the encapsulation of the thermoset polymer, housing body, magnetic sensor and conducting assembly being encapsulated by the outer body.

Detailed Description of the Invention
[030] In accordance with the general objects of the invention in question, it is disclosed a liquid fluid level metering device in confined environment whose magnetic sensor is doubly encapsulated, the first
encapsulating layer being formed by thermoset polymer and the second encapsulating layer formed by thermoplastic polymer. The overlapping of these encapsulating layers ends by defining a general structure, which makes impossible any contact between said magnetic sensor and the external environment to the liquid fluid level metering device in confined environment.
[031 ] This means that, even when submerged in fuel, the magnetic sensor of the liquid fluid level metering device in confined environment will be safe, which should guarantee its perfect functioning, in addition to guaranteeing its maximum service life.
[032] In a preliminary manner, Figures 1 , 2, 3, 4, 5, 6, 7, 8 and 9, hereinafter described in detail, refer only to a possible specific embodiment of the present invention. In addition, certain terms used in the following detailed description should be considered in an inclusive and non-literal manner, always based on the illustrative figures and technical effects achieved.
[033] Figure 1 illustrates the preferred embodiment of the liquid fluid level metering device in confined environment, object of the present invention.
[034] According to this figure it is possible to observe that, generally, said liquid fluid level metering device in confined environment is basically composed of a static body A and a movable body B. The said movable body B is hingedly fastened to the static body A, wherein the functional interaction between these bodies allows the sensing of the liquid fluid level in a confined environment, and the functional principles of this type of sensing, based on Hall Effect, are widely known by those skilled in the art. In this embodiment, the movable body B comprises an extending rod C (partially shown).
[035] However, further details relating to the movable body B (obviously, it comprises at least one magnet (not shown)), the extending rod C and the whip connector D, are omitted here since they are not directly related
to the inventive core of the invention in question. This means that, in general terms, the invention in question, considering only its inventive core, achieves the desired results and technical effects independently of the constructive details of said movable body B, extending rod C and whip connector D.
[036] Figure 2 schematically shows the magnetic sensor 1 , which comprises a Hall Effect sensor basically composed of two functional cores 1 1 (semiconductor chip and electronic circuit) and three electrical terminals 12. It is worth emphasizing that the magnetic sensor 1 , presently illustrated, is a trivial magnetic sensor available in the electronic components market.
[037] Figure 3 shows the conducting assembly 2 that integrates the fluid metering device in a confined environment.
[038] In general terms, said conducting assembly 2 is composed of three metallic bodies designed to shape "electrical extensions" for the three electrical terminals 12 of the magnetic sensor 1 .
[039] According to the main embodiment illustrated, each one of the metallic bodies which integrates the conducting assembly 2 comprises an electrical terminal 21 and a positioning extension 22, both being parallelly arranged at different vertical levels. Preferably, the conducting assembly 2 may be industrially obtained by means of die forging processes.
[040] As shown in Figure 4, there is electrical cooperation between the magnetic sensor 1 and the conducting assembly 2, and for this, each of the three electrical terminals 12 of the magnetic sensor 1 is welded to each of the metallic bodies defining the conducting assembly 2.
[041 ] As shown in Figure 5, the liquid fluid level metering device in confined environment further comprises a housing body 3, which has a "front" housing cavity 31 and a "posterior" housing cavity 32. In addition, said housing body 3 further comprises positioning guides 33 and 34, which comprise
projections and/or channels externally defined from the general contour of the housing body 3, for overlapping the outer body 5.
[042] The housing body 3 also comprises a "central" positioning region 35 and two other "lateral" positioning regions 36. In general terms, said positioning regions 35 and 36 comprise ribs defined in the "posterior" housing cavity 32 of the housing body 3.
[043] Further, as shown in Figure 5, it is noticed that the magnetic sensor 1 and the conducting assembly 2 are both disposed within the housing cavities 31 and 32 of the housing body 3. More particularly, the magnetic sensor 1 is integrally disposed within the "front" housing cavity 31 and the conducting assembly 2 is partially disposed within the "posterior" housing cavity 32.
[044] In this condition, the positioning extensions 22 of the metallic bodies which integrate the conducting assembly 2 cooperate with the positioning regions 35 and 36 of the housing body 3, wherein said positioning regions 35 and 36 of the housing body 3 end by defining limit stops for the metallic bodies which integrate the conducting assembly 2, so as to limit and/or prevent the movement of the entire conducting assembly 2 and, consequently, the movement of the magnetic sensor 1 within their respective housing cavities 31 and 32.
[045] As shown in Figure 6, the entire volume of the housing cavities 31 and 32 of the housing body 3 is further filled by thermoset polymer 4 (epoxy or resin, for example), which acts, as previously mentioned, as the first encapsulation for the magnetic sensor 1 . Obviously, the thermoset polymer 4 also ends by encapsulating the welding region between the magnetic sensor 1 and the conducting assembly 2, in addition to maintaining totally static all the portions of the metallic bodies that integrate the conducting assembly 2 housed in the "posterior" housing cavity 32 of the housing body 3. The joint of the housing body 3 with the thermoset polymer 4 ends by defining a general form
which, after being obtained, it can hardly be undone, even if due to chemical stress.
[046] Further, as shown in Figure 5, considering the preferred embodiment of the invention in question, it is only the electrical terminals 21 of the conducting assembly 2 that are free from this first encapsulation.
[047] Figure 7 shows the outer body 5 which integrates the fluid metering device in confined environment.
[048] In general terms, said outer body 5 defines the second encapsulating layer, which is over-injected above the form defined by the housing body 3 and the thermoset polymer 4 in order to define new encapsulation.
[049] Generally, the outer body 5 comprises a general component whose interior is fundamentally shaped according to the geometry of the form defined by the housing body 3 and the thermoset polymer 4, and whose exterior is shaped according to the installation needs of each design, and such external shape may be variable according to the shape of the over- injection mould.
[050] In any case, the outer body 5 comprises a terminal cover 51 especially dedicated to the protection of the electrical terminals 21 of the conducting assembly 2 which are free from the first encapsulation. Such a terminal cover further has locks 54 for the whip connector D. Additionally, as expected, the outer body 5 further comprises a region 53 dedicated to receiving the movable body B.
[051 ] Further, in relation to the outer body 5, it remains to note that it has its form, by means of over-injection, better oriented due to the support guides 33 and 34 of the housing body 3.
[052] Generally, the sequence of Figures 4, 5, 6 and 7 ends by illustrating the industrial production sequence of the static body A, which is defined by the junction and cooperation between the magnetic sensor 1 , the
conducting assembly 2, the housing body 3, the thermoset polymer 4 and the outer body 5.
[053] Figure 9 shows, in a schematic section, said static body A of the liquid fluid level metering device in confined environment.
[054] As can be observed, at least 95%, but preferably 100% of the total area of the magnetic sensor 1 is encapsulated by the form defined by the housing body 3 and the thermoset polymer 4, wherein this same area (at least 95%, but preferably 100%) is also encapsulated, even indirectly, by the outer body 5.
[055] All of the features explained above are more than sufficient to ensure that all the aforementioned objectives are fully achieved.
[056] Finally, it is also important to emphasize that the above description has the sole objective of describing, in an exemplary manner, the particular embodiment of the invention in question. Therefore, it is clear that modifications, variations and constructive combinations of the elements that perform the same function substantially in the same manner to achieve the same results, remain within the scope of protection defined by the appended claims.
