Description

A VENTILATION ASSEMBLY AND A DUCT THEREOFTECHNICAL FIELDThe present subject matter relates generally to a ventilation assembly and aduct member for a vehicle. More particularly but not exclusively, the presentsubject matter relates to a ventilation assembly and a duct member for a three5 wheeled vehicle.BACKGROUNDConventionally, passenger variant or cargo variant of three or four wheeledvehicles are semi-open type which are less comfortable than ideal design for avehicle as they may expose the occupants to unnecessary pollutants, noises,10 environmental elements such as rains and excessive cold or heat. Thus,several modern three wheelers and even four wheelers are focusing ondesigns that prevent such discomforts to the users by providing a closed cabindesign with user operated windows or half doors at the least. Suchconventional vehicles do not have an effective provision for ventilation,15 either in cabin compartment or in passenger compartment. Requirement ofventilation becomes more essential when the cabin compartment or thepassenger compartment is provided with doors, half-doors or windows. Whenthese doors, half-doors or windows are completely closed, due to bad weatheror other disturbances, there is no scope for natural ventilation in the closed20 cabin design. Further, the provision of air conditioning systems in three-wheeler or four wheeled cargo vehicles would be economically unfeasibleowing to the segment of customers involved in purchasing of three wheelersand four wheeled cargo vehicles.However, the need of economic, compact and effective ventilation system is25 not only limited to three wheelers but also in four wheelers and multi-axlevehicles such as trucks, mini-vans, buses, etc.Also, conventional vehicles introduce air inside cabin through a limitedwindow opening area, only when windows are opened. This may also allowSTLO939259R2024CVR 25 Sep 2024 01:52:05 PM IFormality Examination Report --A VENTILATION ASSEMBLY AND A DUCT THEREOF (1-2024-50326).pdfdust and water into the cabin. When the vehicle is moving at slower speed,this opening area is insufficient to provide comfort to the user.Particularly during the rainy season, conventional vehicles owing to theireconomic feasibility design are not equipped with complex and expensive air5 conditioning system. Further, owing to external harsh conditions, the usersare forced to draw their windows which creates suffocation and / or humidcondition inside the cabin space of the vehicle.Additionally, during normal operative environments of vehicles used inpublic transport, there exists a persistent feeling of suffocation owing to10 crowding in the cabin space. In this scenario, the ventilation provided 1slimited to the area or space opened to the environment.In conventional vehicle layouts relating to four wheeled passenger vehicles,the four wheeled passenger vehicles have bonnet in front of cabincompartment which offers lot of space to package multiple units of heating,15 ventilation, and air conditioning (HVAC) system such as air duct, air blower,condenser / radiator, evaporator, cooling hoses, etc. But for three wheeledvehicles or some types of four wheeled cargo vehicles there are inherentspace constraints and it is a challenge to package ventilation system in aconstrained space.20 Apart from this, HVAC system in four wheeled vehicles not only increasesthe cost and weight of the vehicle but also consumes energy from the primemover of the vehicle which reduces the mileage of the vehicle. But invehicles such as three-wheeled vehicles involved in public transport, mileageis very important and hence we cannot increase load on engine.25 Therefore, there is a need of an improved ventilation system whichovercomes the above cited problems of the prior art and which is simple,light-weight, economical, cost-effective, offers ease of serviceability andprovide an effective packaging efficiency.STLO0939259R2024CVR 25 Sep 2024 01:52:05 PM 2Formality Examination Report --A VENTILATION ASSEMBLY AND A DUCT THEREOF (1-2024-50326). pdfBRIEF DESCRIPTION OF THE DRAWINGSThe details are described with reference to an embodiment of a ventilationassembly and a duct member for a vehicle along with the accompanyingfigures.
