Description

DESCRIPTION

THERMAL INSULATION DEVICE FOR VEHICLES

Technical field

The present invention falls within the field of vehicle accessories, particularly vehicle windshield accessories. More specifically, the subject of the invention relates to a thermal insulation device for use on heated windshields and rear windows of vehicles.

Background

To prevent excessive heating of the vehicle's passenger compartment and interior elements, such as seats, steering wheel, etc., under direct sunlight, sunshades are used. These include a sheet-like body, usually foldable, designed to cover the windshield or rear window, either inside or outside. The body is made of opaque material and, preferably, can be a heat-insulating material, such as cardboard, and/or can be coated with a reflective material, such as aluminum.

The described sunshade, however, is not capable of preventing freezing, or at least frost formation, on the windshield or rear window when used from the inside, or in extremely cold conditions.

Summary description of the invention

The present invention features a thermal insulation device for vehicles, according to independent claim 1, which combats inclement weather conditions, both heat and cold. Other optional advantageous embodiments of the insulation device of the invention are explained in the "detailed description of an exemplary embodiment" section, as well as in the independent claims.

In particular, the device of the invention comprises a sun visor, intended to cover, at least in part, a windshield of a vehicle, where the sun visor comprises in turn:

- a laminar body provided with:

- a first side made of opaque material and intended to receive incident sunlight, to prevent heating of the vehicle's interior; and

- a second side, opposite the first side.

The body also has:

- one or more electric resistors for heating the body on the second side so that, when the second side is placed against the glass, the glass is heated to prevent the formation of ice or frost; and

- a power socket to power the resistor or resistors from a power source

The device of the invention can be used in summer, to prevent overheating in the vehicle's passenger compartment, and also in winter, preventing freezing or frost formation on the front and/or rear windows of the vehicle.

This device is designed to prevent the inconvenience caused to parked vehicles, both in summer, due to the heating of the passenger compartment, and in winter, in certain locations, by having to scrape the vehicle's windows to remove ice and be able to drive. In particular, in winter, the user can, upon reaching their destination, set up the sunshade with the pre-charged battery, so that upon returning to their vehicle, the windows are free of ice or frost, avoiding the need to scrape.

Detailed description of an embodiment

A detailed description of a preferred embodiment of a thermal insulation device for vehicles according to the present invention is given below with the aid of the aforementioned figures 1-2.

The insulation device includes, as shown in Figure 1, a sunshade (1) intended to cover, at least in part, a window (such as a windshield or a rear window) of a vehicle, and comprising a laminar body (2) provided with a first face (3) and a second face (4), see Figure 2, opposite the first face (3). The first face (3) is intended to receive incident sunlight, to prevent heating of the vehicle's passenger compartment. To this end, the body (2) is manufactured, at least on the first face (3), of opaque material, such as cardboard, fabric (natural or synthetic) or plastic. Preferably, the body (2) is foldable through folds (5). Optionally, the first face (3) is manufactured or, at least, coated, with a reflective material, such as aluminum, for greater effectiveness.

For its part, the body (2) has, preferably closer to the second face (4), one or more electrical resistors (6) for heating the body (2) on the second face (4) and which, when the second face (4) is arranged against the windshield, heat the windshield to prevent the formation of ice or frost. The body (2) additionally includes a power socket (7), for example a USB socket, for supplying the resistors (6) through, for example, a cable (8), from a power source. Preferably the resistor (6) or resistors (6) extend along the body (2). According to a first example, the resistors (6) are supplied directly, by means of the cable (8), from an electricity source of the vehicle itself, which acts as the aforementioned power source, which allows the device to be used with the vehicle started. According to a second example, the resistors (6) are powered, also by means of the cable (8), from an accumulator (9) included in the device of the invention, and which acts as the aforementioned energy source, which allows the device to be used both with the vehicle started and stopped, so that the resistors (6) can be heated in advance or immediately before the start of the trip.

The accumulator (9), together with the cable (8), allow, with reduced dimensions, a rapid charge from the vehicle's electricity source, being able to supply the resistors (8) with sufficient energy for ten hours and be charged while driving, or through the mains, with an adapter if necessary. The accumulator (9) can be for general use, or for specific use for the invention.

The accumulator (9) may have a charge level display (10). It may also include a control (11) to control the intensity of the current supplied, either to allow the user to select an intensity level, for example, as a percentage, or, in collaboration with a thermostat, so that the current intensity is such that it does not allow the glass to fall below a previously defined temperature, either by the programming of the accumulator (9) itself or by the user.

Finally, the sun visor (1) may include fixing means for fixing the body (2) inside the passenger compartment, such as, for example: suction cups, for fixing the body to the windshield; or ropes (12), for fixing the body to internal elements of the passenger compartment, such as projections, hooks, etc.
