Definitions

  • the present invention relates to a windshield for motor vehicles, particularly motorcycles with two or more wheels but also four-wheel "light” vehicles for urban mobility, having the features specified in the preamble of independent claim 1.
  • a windshield of the above-mentioned type is known for example from EP 1 759 969.
  • the windshield according to the present invention allows to protect the driver of the vehicle, and at least partially also the passenger, if any, from the external atmospheric agents, particularly from the rain, creating a shield for the rain and conveying air, previously heated, if necessary, towards the driver.
  • Motor vehicles are known which are conceived and designed particularly, though not exclusively, for urban mobility. Such vehicles are specifically conceived to provide, in addition to the handling and ease of use of a motorcycle, the stability and comfort of a motorcar, offering therefore in particular a good aerodynamic protection and a good protection against external atmospheric agents.
  • a motorcycle or a scooter either with two wheels or with three or four tilting wheels
  • such a vehicle is typically used for daily journeys to and from the workplaces, irrespective of the weather conditions, even in winter with particularly low temperatures and/or in rainy days.
  • the driver since such a kind of vehicle, as is known, does not have a real bodywork, the driver is not protected by a roof or by side doors or windows, as it is the case with a motorcar provided with a bodywork. The driver, as well as the passenger, if any, is therefore exposed to atmospheric agents, particularly to the rain.
  • the driver as well as the passenger, if any, is exposed to low temperatures during winter, and when the vehicle is traveling the temperature actually perceived is even lower than the air temperature.
  • windshields that are very wide in order to protect as much as possible the driver adversely affect not only the vehicle aerodynamics, particularly at high speed, but also the handling of the steering handlebar at low speed. Furthermore, very wide windshields reduce the driver's visibility in case of rain, in particular at low speed, as the air is not able to make the drops run off the surface of the windshield and therefore the drops collect on the surface of the windshield and thus reduce the driver's visibility.
  • the invention is based on the idea of making a windshield provided with at least one motorized impeller for conveying air from outside towards the base portion of the main body of the windshield. Due to the provision of such motorized impeller(s), even when the vehicle is stationary or traveling at low speed it is possible to generate an air flow through the hollow space of the windshield and hence to generate an air blade, flowing out of the upper opening of the windshield, above the head of the driver of the vehicle.
  • Figures 1 and 2 are respective perspective views that schematically show a windshield according to a first embodiment of the present invention, installed on board of a motor vehicle;
  • Figure 3 is a side view of a motor vehicle, particularly a motor vehicle with three tilting wheels, provided with the windshield of Figures 1 and 2;
  • Figure 4 schematically shows the air flow that during operation flows through the windshield of Figures 1 and 2;
  • Figure 5 is a side view, sectioned through a vertical section plane, of the windshield of Figures 1 and 2;
  • Figure 6 is a perspective, partially exploded view of the windshield of Figures 1 and 2;
  • Figures 7 and 8 are respective perspective views that schematically show a windshield according to a second embodiment of the present invention, installed on board of a motor vehicle;
  • Figure 9 is a side view of a motor vehicle, particularly a motor vehicle with three tilting wheels, provided with the windshield of Figures 7 and 8;
  • Figure 10 schematically shows the air flow that during operation flows through the windshield of Figures 7 and 8;
  • Figure 11 is a perspective view schematically showing a windshield according to a third embodiment of the present invention, installed on board of a motor vehicle;
  • Figure 12 is a side view of a motor vehicle, particularly a motor vehicle with three tilting wheels, provided with the windshield of Figure 11;
  • Figure 13 schematically shows the air flow that during operation flows through the windshield of Figure 11 ;
  • Figures 14 and 15 are perspective views that schematically show a windshield for motor vehicles according to respective further embodiments of the present invention.
  • the attached drawings show, by way of example, some embodiments of a windshield 1 for a motor vehicle with two or more wheels according to the present invention.
  • the windshield 1 comprises a main body 2 made of transparent material, preferably plexiglas or other suitable material.
  • the main body 2 comprises an upper edge 3 and a base portion 4, the latter comprising in turn an inlet manifold 5 (see Figures 4 and 6) configured to convey an air flow F from the outside of the windshield 1 towards the base portion 4 of the main body 2.
  • the main body 2 In order to better convey the air flow F towards the upper edge 3 of the main body 2, the main body 2 also has at least one hollow space 7 (Figure 5) configured to convey the air flow F coming from the inlet manifold 5 of the base portion 4 towards the upper edge 3 of the main body 2.
  • the main body 2 has a sandwich-like structure including an outer panel 2a and an inner panel 2b which are advantageously made of plexiglas and define the hollow space 7 therebetween.
  • the upper edge 3 of the main body 2 advantageously comprises at least one outlet opening 30 for allowing the air flow F to flow out of the main body.
  • an outlet manifold 31 configured to accelerate the air flow F conveyed by the hollow space 7.
  • the outlet manifold 31 may have a flow area restriction, as can be seen for example in the section view of Figure 5, so that the air blade flowing at high speed out of the outlet opening 30 provided at the upper edge 3 of the main body 2 of the windshield allows to divert the rain from the head of the driver, which will then remain dry even (see in particular Figure 3).
  • the inlet manifold 5 comprises an impeller 6 (or alternatively more than one impeller) operated by a motor (not shown), preferably an electric motor, to convey the air flow F from the outside into the inlet manifold 5 even when the vehicle is stationary or traveling at low speed.
  • a motor not shown, preferably an electric motor
  • the impeller 6 (but the same applies also to the case of more than one impeller) may be controlled by the user, for example via a control unit (not shown) controlling the motor that operates the impeller 6.
  • a control unit (not shown) controlling the motor that operates the impeller 6.
  • an operating button or lever (not shown) is advantageously provided on board of the vehicle, for example on the steering handlebar or wheel or on the dashboard, to allow the user to control the impeller(s), especially when the vehicle is stationary or traveling at low speed.
  • the impeller 6 When the impeller 6 is operated, it generates an air flow F that is conveyed from the outside, through the inlet manifold 5, into the hollow space 7 provided in the main body 2 of the windshield 1 and then from the hollow space 7 towards the outlet opening 30 at the upper edge 3 of the main body 2 of the windshield 1.
  • the air flow F leaving the outlet opening 30 generates an air blade above the head of the driver, which protects the driver from the rain even when the vehicle is stationary or traveling at low speed.
  • FIG. 7 to 10 A second embodiment of the windshield 1 according to the present invention is shown in Figures 7 to 10, where parts and elements identical or corresponding to those of the embodiment of Figures 1 to 6 are indicated with the same reference numerals.
  • the hollow space 7 extends only along the perimeter edges of the main body 2 of the windshield 1.
  • the hollow space 7 comprises a first side portion 7a and a second side portion 7b that are joined to an upper portion 7c placed at the upper edge 3 of the main body 2.
  • the side portions 7a and 7b and the upper portion 7c are provided with respective outlet openings, which are indicated with 30a and 30b as far as the side portions 7a and 7b, respectively, are concerned and with 30 as far as the upper portion 7c is concerned, and through which the air flowing through the hollow space 7 can flow out of the windshield.
  • the outlet openings 30a and 30b of the side portions 7a and 7b of the hollow space 7 are arranged so as to be facing, in the mounted condition of the windshield on board of the vehicle, towards the driver of the vehicle.
  • the windshield 1 generates not only an upper air blade (flowing out of the upper outlet opening 30) forming a barrier above the head of the driver, but also side air blades (flowing out of the side outlet openings 30a and 30b) that allow to improve the comfort of the driver, especially at high speed.
  • the air flowing out of the windshield 1 may be heated by suitable heating means, for example electrical resistances, placed preferably close to the impeller(s) of the inlet manifold 5. Clearly, this allows to further improve the comfort of the driver of the vehicle.
  • suitable heating means for example electrical resistances, placed preferably close to the impeller(s) of the inlet manifold 5.
  • Such heating means may also be provided for in the first embodiment of Figures 1 to 6.
  • the inlet manifold 5 is configured to split the air flow F coming from the outside into a first air flow FI that flows through one of the two side portions 7a and 7b of the hollow space 7, namely the portion 7a, and a second air flow F2 that flows through the other side portion 7b.
  • each of the two side portions 7a and 7b extends along the upper edge 3 of the main body 2 with a first upper portion 7c' and a second upper portion 7c", respectively.
  • Each of the two side portions 7a and 7b and of the two upper portions 7c' and 7c" has a respective outlet opening for allowing the air to flow outwards. More specifically, with reference to Figure 13, the first side portion 7a has a first side outlet opening 30a, the second side portion 7b has a second side outlet opening 30b, the first upper portion 7c' has a first upper outlet opening 30' and the second upper portion 7c" has a second upper outlet opening 30".
  • the windshield 1 allows to spread in a more varied way the air flowing out of the windshield.
  • selector means arranged for example on the steering handlebar or wheel or on the dashboard of the vehicle, to allow the driver to manage the air flows through the outlet openings 30a, 30b, 30' and 30".
  • the inlet manifold 5 is provided with a motorized impeller 6, so as to be able to generate an air flow towards the hollow space 7 even in case the vehicle is stationary or traveling at low speed.
  • Figures 14 and 15 where parts and elements identical or corresponding to those of the embodiments of Figures 1 to 13 are indicated with the same reference numerals, show a windshield 1 having a structure like the one of the third embodiment described above, that is to say, with a hollow space including two side portions having respective outlet openings 30a and 30b and two upper portions having respective outlet openings 30' and 30".
  • the inlet manifold 5 is provided with a plurality of motorized impellers 6, instead of a single one, namely two impellers 6 in the example of Figure 14 and four impellers 6 in the example of Figure 15.
