Technical Field

The invention relates to a battery charger for an electric or hybrid vehicle.

Background

Many known battery chargers for electric or hybrid vehicles are used to charge batteries typically mounted on such vehicles in order to power various electronic devices (e.g., engines, control units, lights, etc.).

In particular, this type of battery charger is provided with an electronic device for recharging the battery, as well as with housing means of the electronic device itself, which are intended to protect and facilitate the installation of the latter in the motor vehicle.

Typically, the housing means defines a housing chamber for the electronic device and is provided with a plurality of connectors to access the housing means in order to operatively connect the electronic device to the battery and/or other electronic components, such as control cards, sensors, etc.

In particular, the containing devices of known type are generally provided with two half-shells which can be connected to each other and respectively define two half-cavities which, when connected , define a containing chamber of the electronic apparatus.

Advantageously, the two half-shells are generally made of metal, which must be machined by means of an injection-molding process which allows to define the shape of the two half-shells and to form a particularly durable and long-lasting housing means.

However, the die-casting process for manufacturing this type of containment device is generally expensive and the resulting half-shells are extremely heavy and bulky, thus adversely affecting the cost and performance of the motor vehicle.

In order to overcome the above-mentioned problems, it is increasingly common to produce battery chargers comprising a containing device provided with a container body defining a containing chamber of the electronic equipment and having a corresponding closing body which is removably associated with the container body to close the containing chamber so as to protect the electronic equipment.

In particular, the enclosure is substantially flat and does not require expensive die casting processes to manufacture, making the containment device significantly less expensive and lighter than the containment devices described above.

However, even this type of containment devices involves related improvements in their strength and durability.

In practice, the battery charger is generally subjected to continuous stresses, such as mechanical and/or thermal stresses mainly caused by the operation of the motor vehicle, and this can affect the enclosure in particular, since, given its plate-like shape, it is often subject to deformations that are particularly significant over time.

This deformation in fact impairs the construction of the enclosure and therefore does not completely seal the containment chamber, so that the electronic equipment is exposed to a serious risk and may cause serious damage to the motor vehicle.

Furthermore, it is very common for liquid deposits to be present on the enclosure, for example due to condensation of air in contact with the enclosure or due to infiltration and/or leakage.

In particular, if not removed in a short time, such liquid deposits can affect the material from which the closure is made, thereby compromising the integrity of the closure and accelerating the deformation process described above.

fig. 2 is a top view of a battery charger according to the present invention.

Detailed Description

With particular reference to the figures, reference numeral 1 generally indicates a battery charger for electric or hybrid vehicles.

In particular, the battery charger 1 for electric or hybrid vehicles comprises:

-at least container bodies 2, which container bodies 2 are mountable on a motor vehicle and define at least containment chambers;

-at least electronic devices housed within the housing compartment, the electronic devices being connectable to at least batteries of the motor vehicle and configured to recharge the batteries;

at least closing bodies 4 of the container body 2, which closing bodies 4 are associated with the container body 2 in a detachable manner to close the receiving chamber.

Suitably, the enclosure 4 is adapted to protect electronic equipment housed within the containment chamber.

Preferably, the container body 2 has a plurality of side walls adjacent to each other and bottom walls defining a containing chamber with the side walls .

In the particular embodiment illustrated, the container body 2 comprises four substantially flat shaped side walls and a substantially flat shaped bottom wall to define a substantially rectangular shaped container body 2.

However, alternative embodiments of the battery charger 1, in which the container body 2 comprises a different number of side walls, so as to form container bodies 2 of different shapes (for example square), cannot be excluded.

Advantageously, the battery charger 1 comprises removable association means of the closing body 4 with the container body 2.

Preferably, the association means are of known type, for example a screw and nut fixing system.

In particular, the enclosure 4 is substantially plate-shaped.

As such , the enclosure 4 allows for sealing the containment chamber and protecting the equipment, thereby minimizing the size and weight of the battery charger 1.

Advantageously, the closing body 4 comprises stiffening means shaped and arranged to prevent deformation of the closing body itself.

In particular, the reinforcing means comprise at least reinforcing elements 5 made on at least the portion of the closing body 4.

With reference to the embodiment shown in the figures, the reinforcing means comprise a plurality of reinforcing elements 5 made on at least the portion of the closing body 4.

Further, the reinforcing element 5 is linear.

However, alternative embodiments of the stiffening means, i.e. wherein the stiffening element 5 has a different shape, e.g. a curved shape, cannot be excluded.

Advantageously, at least of the reinforcing elements 5 are arranged substantially parallel to another reinforcing elements 5.

Furthermore, at least of the reinforcing elements 5 are arranged substantially transversely to the other reinforcing elements 5.

In detail, according to the illustrated embodiment, the battery charger 1 comprises eight reinforcing elements 5, three of which extend parallel to each other along an th direction of extension and five of which extend parallel to each other along a second direction of extension substantially perpendicular to the th direction of extension, as shown in fig. 2.

However, alternative embodiments of the battery charger 1 cannot be ruled out, i.e. wherein the reinforcement means comprise a different number of reinforcement elements 5, these reinforcement elements 5 being arranged according to different combinations of reinforcement elements 5 (parallel, transverse and/or orthogonal to each other) so as to adapt to the shape of the enclosure 4.

As such , the reinforcing element 5 forms a reinforcing mesh extending substantially over the entire extension of the enclosure 4, so as to reinforce its structure at each point in a substantially uniform manner.

In particular, the reinforcing elements 5 distributed in this way give the enclosure 4 a particular resistance to deformation and a particular durability, reducing the risk of compromising the protection of the electronic equipment.

Conveniently, the reinforcing means comprises at least liquid drains.

In particular, the enclosure 4 comprises a plurality of peripheral sides 6 defining an outer surface 7 of the containment chamber, and the evacuation means comprise at least evacuation channels 9, the evacuation channels 9 being formed on the outer surface 7 and being provided with at least evacuation openings 8 at of the peripheral sides 6.

Advantageously, the evacuation channel 9 is able to evacuate the majority of the liquid deposited on the outer surface 7 of the enclosure 4, in particular such as liquid resulting from condensation of air or from leakage and/or infiltration coming into contact with the enclosure 4.

Advantageously, the drainage channel 9 collects the liquid deposited on the outer surface 7 and conveys it outside the enclosure 4, i.e. it conveys the collected liquid to the drainage opening 8, through which the liquid itself leaves the enclosure 4.

In more detail, the discharge means comprise a plurality of discharge channels 9, wherein at least discharge openings 8 are arranged at each peripheral side 6.

Preferably, each discharge channel 9 passes through the outer surface 7 extending substantially between its two peripheral sides 6, the two peripheral sides 6 being arranged substantially opposite to each other.

In other words, each discharge channel 9 is provided with an end arranged in the vicinity of the peripheral side 6, which peripheral side 6 is substantially opposite to the peripheral side 6 where the discharge opening 8 is placed.

Furthermore, at least of the discharge channels 9 are fluidly connected to at least another of the discharge channels 9 and arranged substantially transverse to the at least another of the discharge channels 9.

In other words, each discharge channel 9 communicates with at least another discharge channels 9 intersecting it, so that collected liquid can easily pass from discharge channels 9 to another discharge channels 9.

In particular, according to the illustrated embodiment, the discharge channels 9 cross each other at a plurality of points.

As such , the discharge channels 9 form an interconnected collection network covering substantially the entire outer surface 7 and provided with a plurality of discharge openings 8 communicating with any discharge channel 9.

In fact, this collection network allows the liquid to be removed to reach the discharge opening 8 even in the event of a change in the position of the battery charger 1, for example a change in the inclination of the enclosure 4 and therefore of the outer surface 7 caused by the operation of the motor vehicle.

Advantageously, according to the illustrated embodiment, the reinforcing element 5 coincides with the discharge channel 9.

In particular, the reinforcing element 5 comprises at least concave cross-sections for defining the discharge channel 9.

In more detail, at least of the reinforcing elements 5 and the evacuation channels 9 are made on the outer surface 7 by a moulding process of the closing body 4.

Advantageously, the reinforcing element 5 and the discharge channel 9 are made by secondary compression molding, this secondary compression molding allowing the manufacture of the cross section of the reinforcing element.

Preferably, the process is performed to manufacture the enclosure 4.

The described invention has been determined in practice to be able to achieve the intended aim.

In particular, the construction and arrangement of the reinforcing element may be such that the reinforcing mesh is evenly distributed over the entire closure element, giving it a particular resistance to deformation and better durability over time.

In addition, the presence of the evacuation means makes it possible to remove efficiently and effectively the liquids that may deposit on the external surface, which, if not removed, may compromise the integrity of the material from which the enclosure is made over time.

Furthermore, the use of a moulding process to manufacture the reinforcing element makes it possible to reinforce the structure of the enclosure without imposing more weight on the battery charger.

In detail, the particular configuration of the reinforcing element allows its manufacture and the manufacture of the evacuation channel by compression molding of the closure body.

In fact, this particular configuration allows the reinforcing element to substantially coincide with the discharge channel.
