Definitions
- the present invention belongs to the field of electronic components responsible for the connectivity of a motorized land vehicle.
- it relates to the passive cooling of a connectivity box housed in an opening in the roof of the vehicle.
- Motor land vehicle means any type of vehicle such as a motor vehicle, a moped, an airplane, a train, a motorcycle, a storage robot in a warehouse, etc.
- “Housed in an opening in the roof” means that the connectivity box is placed in the opening. In particular, it can be inserted into a housing (cavity of the bodywork dedicated to receiving the case) then glued or screwed. In one embodiment, the box is glued or screwed to the bodywork, above an opening.
- the latest generation connectivity boxes are generally linked directly to an exterior surface of the vehicle. Such an arrangement poses problems of overheating of the electronic components included in the case. These electronic components themselves generate significant thermal energy (heat) and, by their arrangement on the bodywork, are subject to the thermal energy provided by the external environment.
- a connectivity box itself generating significant thermal energy housed in a body painted in a dark color (body color), receiving direct sunlight can see its operation degraded.
- An insulating foam configured to define a cooling tank of the connectivity box, the cooling tank being included in an intermediate space formed between the roof and the headliner; wherein the headliner has an air vent configured for airflow between the passenger compartment and the coolant reservoir.
- the cooling tank thus defined puts cool air, or less at least less hot, to the device of the connectivity box.
- the circulation of air with the passenger compartment allows the tank to be at a temperature close to that of the passenger compartment.
- the cooling reservoir is located under the connectivity box.
- the sun's rays on the body do not heat the tank.
- the insulating foam conforms to a contour of the underside of the connectivity box.
- the sun's rays on the body do not heat the tank.
- the insulating foam is assembled by clipping to the connectivity box.
- the foam is very simple to assemble.
- a second aspect of the invention relates to a method for mounting a motorized land vehicle according to the first aspect of the invention, the method comprising:
- the second assembly step comprising at least partial crushing of the foam on the headliner.
- FIG 1 is a diagram illustrating a roof of the vehicle comprising the connectivity box according to one embodiment of the invention
- FIG 2 is a diagram illustrating the connectivity box according to one embodiment of the invention.
- FIG 3 is a diagram illustrating the underside of the connectivity box with a foam according to one embodiment of the invention.
- FIG 4 is a diagram illustrating a view of the connectivity box housed in the pavilion according to one embodiment of the invention.
- the invention is described below in its non-limiting application to the case of a connectivity box installed on a roof, also called a roof, of a motor vehicle.
- a connectivity box installed on the handlebars of an electric bicycle or placed on a headlight of a moped are also possible.
- FIG. 1 is a diagram illustrating a roof of the vehicle comprising the connectivity box according to one embodiment of the invention.
- Figure 1 shows the roof 2 (part of the roof is shown in Figure 1) of the vehicle.
- the connectivity box 4 is included on the roof.
- the box 4 is housed in an opening in the roof, as will be illustrated in Figure 4.
- the visible face of the flag in Figure 1 is located outside the vehicle.
- Figure 2 is a diagram illustrating the connectivity box according to one embodiment of the invention.
- the connectivity box 4 comprises an antenna 41 and a processing box 42.
- the antenna of the shark fin type, comprises several antennas according to the communication channels concerned (wifi, cellular, etc.) which are connected to components present in the box 42. Said components are configured to process, and therefore for example to modulate/demodulate, the signals received by the antennas.
- Figure 3 is a diagram illustrating the underside of the connectivity box with a foam according to one embodiment of the invention.
- the bottom of the connectivity box 4 is represented here, in particular a lower part of the processing box 42.
- An insulating foam 8 is assembled to the connectivity box. As will be detailed below with reference to FIG. 4, the foam thus forms a cooling reservoir under the connectivity box. In particular, the insulating foam follows a contour of the lower face of the connectivity box.
- FIG. 4 is a diagram illustrating a view of the connectivity box housed in the pavilion according to one embodiment of the invention.
- An intermediate space is present between the roof 2 and the trim 12. It is in this space that the cooling tank 14 is included.
- a lower front part 81, an upper front part 82 and a rear part 83 of the foam 8 are shown. Indeed, in Figure 4, the front part (consisting of parts 81 and 82) of the foam is not compressed to illustrate the positioning of the foam. In reality, once the trim is assembled to the roof on which the connectivity box was previously assembled, the front part consisting of parts 81 and 82 is compressed so that part 81 is no longer present and the entire part before compressed at the level of the part 82.
- the rear part 83 can also be compressed, depending on the shapes of the roof and the passenger compartment of the vehicles.
- a cooling tank 14 is included in the intermediate space.
- the roof lining 12 comprises a ventilation grille 10 configured for air circulation between the passenger compartment and the cooling tank.
- the air is therefore exchanged with the passenger compartment and thus provides active cooling devices, such as a fan, of the connectivity box with fresh air.
- One embodiment of the invention relates to a method for mounting a motorized land vehicle according to the first aspect of the invention, the method comprising:
