Description

The present disclosure relates to a venting arrangement for the selective opening and closing of an enclosed space. Furthermore, the present disclosure relates to a vehicle. While motor vehicles are in operating/driving mode, the interior remains closed by a hatch, similar to a door. The hatch incorporates one or more seals to create a tight seal against the vehicle body, preventing dirt, water, and noise from entering the interior. The seal also prevents air from escaping once the hatch is closed, thus maintaining air pressure inside the vehicle. To reduce the build-up of air pressure inside the vehicle when closing the hatch, some vehicles are equipped with passive pressure relief valves. These valves open in response to increased air pressure, allowing air to escape and facilitating hatch closure. They often incorporate a flexible baffle, such as rubber, which opens as the pressure rises during hatch closing. Once the internal pressure equals the external ambient pressure, these valves are designed to close automatically. The DE 10 2015 222803 A1 describes a device for generating movement of a component of a vehicle (40), which has an actuator element that is operationally connected to the component and generates translational and/or rotational movement. Furthermore, describes DE 10 2015 222803 A1 A vehicle equipped with a device for providing movement to a component of the vehicle. However, the device system is complex and not cost-effective. The WO 2013 185012 A1 This describes a vehicle ventilation system comprising one or more flexible membranes to direct airflow at the request of a vehicle occupant. The membranes can be used individually, pre-assembled with other parts of the ventilation system, or formed as a single-piece frame and then installed within the system. The flexible membranes can create compartments within the ventilation system to direct air into the vehicle interior. They can also be used as seals or peripheral panels between internal ventilation components and peripheral elements, such as a ventilation plenum. There is a need to develop a cost-effective and safe system to reduce the build-up of air pressure in the vehicle. Against this background, the purpose of the present disclosure is to provide an improved venting system. In particular, it is to develop a cost-effective venting system for discharging the air pressure that builds up inside the vehicle. At least one of these tasks is achieved by a venting arrangement having the features of claim 1 and/or by a vehicle having the features of claim 20. Preferred embodiments are the subject of the dependent claims. According to one aspect of the present disclosure, a venting arrangement for selectively opening and closing an enclosed space, particularly in or for a vehicle, is disclosed. The venting arrangement can comprise at least one set of modules, each module comprising a first module and a second module arranged in a sequence and coupled to each other via at least one contact surface. The first module can comprise a first housing and at least one first baffle, and the second module can comprise a second housing and at least one second baffle. At least one actuating mechanism can be configured to be attached to at least one set of modules and coupled to the first and/or second baffle of the set of modules to open and close at least one first baffle and/or at least one second baffle. In one embodiment, the first module may further comprise a first deformation element, a first pair of levers, and a fastening mechanism. The first housing may include an engagement side for fastening the at least one first guide wall. At least one edge of the at least one first guide wall may be freely attached to the first housing. In one embodiment, the fastening mechanism can be arranged and configured to pass through two opposite sides of the first housing to connect the first pair of levers and to allow a pivoting movement of the first pair of levers relative to the first housing. In one embodiment, the first deformation element can comprise a raised section and two free ends. The two free ends can be pivotally connected to a first end. The first pair of levers is connected, and the pivoting movement of the first pair of levers can be configured to guide the two free ends in a guide area on two opposite sides of the first housing. The raised section of the first deformation element can be configured to open and close the at least one first guide wall. The first end of the first pair of levers may include a slot to pivotally attach the two free ends of the first deformation element, and the slot may be configured to allow the first deformation element linear movement in the guide area. In one embodiment, the second module can include a second deformation element and a second pair of levers. The second housing can include an engagement side for attaching the at least one second guide wall. At least one edge of the at least one second guide wall can
