It is related to systems. The invention specifically concerns optics that maintain field of view on a fixed carrier structure attached to a vehicle. The vehicle operates kinematically separated from the reflective element in terms of movement; 10 Angular displacement around a joint axis due to the effect of aerodynamic forces generated during movement. a position-changing; pre-tensioned towards the initial position by a passive elastic element and preferably containing an aerodynamic outer shell stabilized by means of a damping element. It relates to the vehicle's side mirror assembly. STATE OF THE ART Vehicle exterior mirrors, due to their structure extending outwards from the vehicle body, are a visual feature of the vehicle. During its movement, it interacts with the airflow, and as a result of this interaction, it exhibits aerodynamic properties. drag, flow separation, vortex formation, pressure fluctuations, and wind-generated noise. These effects can occur. These effects increase especially at high vehicle speeds, 20 the vehicle's fuel / energy consumption and aerodynamic loads on the mirror structure This can affect the aerodynamic behavior of the vehicle's exterior mirrors. various movable or aerodynamically shaped mirror structures for improvement It has been improved. In the known state of the art, the external rearview mirror is mounted on a carrier 25 that is fixed to the vehicle body. It has a mirror housing that can move depending on the section and the aforementioned the housing can be moved to different angular positions around a hinge or pivot axis It is known. US7073914B2 was identified in a literature search conducted on the known state of the art. In patent document number 30, the vehicle's exterior rearview mirror is described as having a fixed mounting section. that it has a movable mirror housing and the mirror housing moves according to the vehicle speed or different angular angles depending on the operating conditions determined by a control system. It is explained that they were brought to these positions. In the document mentioned, the movement of the mirror housing is described. reducing aerodynamic drag and associated wind noise by making it less efficient. 2 The aim is also to improve the visibility of the reflective element as the position of the movable housing changes. The orientation of the reflective element can also be adjusted in order to protect the area. It is anticipated. However, the innovation introduced by the document in question is mirror image. The movement of its housing is primarily via an actuator and control system. This is being done. Therefore, the exterior mirror housing is protected against damage that occurs during vehicle movement. By using the incoming aerodynamic force as a direct driving effect, an external main for automatic angular position change without the need for a motion actuator There is no passive mechanism. In the current state of technology, vehicle exterior mirrors utilize airflow. It is also known how mechanical motion is generated. The literature on known techniques includes 10 The patent document numbered US3712703A, identified in the research, describes the vehicle's exterior design. The presence of fins that rotate around the mirror with the airflow and air direction By means of its elements, the airflow is directed to these fins, creating a mirror-like effect. The rotation around the axis is explained. In this structure, the airflow is connected to the mirror. It generates force on the fins, causing the mirror to rotate. 15 The document also describes how to direct airflow with an aerodynamically shaped housing and It is also foreseen that it will be accelerated. However, the document in question states that it is being moved. The essential element is the mirror itself, which carries the reflective surface, and the airflow obtained from it. movement, especially due to the centrifugal effect of moisture or foreign matter accumulating on the mirror surface It is used to divert attention. Therefore, the direction of vision of the reflective element is 20 only the aerodynamic outer shell, independent of a fixed optical core that protects it by moving the object and balancing that movement with a passive elastic countermoment. This is a structure designed to achieve different stable angular positions at different air speeds. This is not explained in the document. In conclusion, a 25 is a motion-separated core from a fixed core that carries the optical vision function. the outer shell is powered by air force without requiring any main electric shell actuator. spontaneous change of position; balance of movement by elastic return force; sudden Damping against wind, turbulence, and road vibrations; mirroring during movement preserving the viewing direction of the glass and contact between the shell and the fixed optical core. A structure is needed that prevents this from happening. 30 THE PURPOSE OF THE INVENTION The main purpose of the invention is to adjust the optical reflective element in the vehicle's exterior rearview mirror to provide a more accurate view. while maintaining its position, it is separated from the optical reflector element in terms of movement. the aerodynamic outer shell from the relative airflow generated during the vehicle's movement 3 enabling passive angular position change due to the effect of the resulting aerodynamic force. The goal is to create an outer shell system. The purpose of the invention is to demonstrate the effect of the resultant aerodynamic force on the aerodynamic outer shell. There is a non-zero difference between the line and the joint axis that enables the movement of the outer shell. By creating a moment arm, an aerodynamic rotational moment of 5 is generated that enables the movement of the outer shell. The goal is to ensure it is obtained. Another purpose of the invention is to transfer the aforementioned aerodynamic moment to the outer shell at the beginning. by balancing the counter-moment of the passive elastic element that directs it to its position, the outer shell Instead of simply moving between two predetermined positions, it depends on the relative airspeed. The aim is to enable it to assume different stable angular positions depending on the situation. 10 Another aim of the invention is to adjust the angular movement of the aerodynamic outer shell depending on the change in vehicle speed. the spontaneous change in position and the effect of the elastic element on the outside when the vehicle speed decreases by allowing the shell to return to its starting position, any intermediate electrical a passive aerodynamic adaptation mechanism that does not require a motion actuator to provide. 15 Another aim of the invention is to ensure that the aerodynamic outer shell takes into account airflow, crosswind, turbulence, and Sudden or repetitive changes that may occur under variable aerodynamic effects such as vehicle wake flow by limiting its oscillations, the outer shell is controlled around a stable angular position. It offers a damping structure that allows it to move. Another purpose of the invention is to provide an optical reflector during the movement of the aerodynamic outer shell. the element's line of sight is essentially preserved and the movable outer shell and optical reflector a way to prevent mechanical contact from occurring between the element and the fixed supporting structure The goal is to provide motion geometry. Another aim of the invention is to apply this passive aerodynamic motion principle to different types of vehicles. and the outer shell 25 can be adapted to different airflow conditions on the vehicle. through its geometry, joint position, elastic element pre-stress and damping characteristics The aim is to provide it in an adjustable structure. To achieve these purposes, the invention involves a fixed carrier structure that can be attached to a vehicle. movement from an optical reflective element that maintains the located and adjusted viewing position. the aerodynamic outer shell separated in terms of the aerodynamic 30 acting on that outer shell Aerodynamics generated by the moment arm between the force and the joint axis its movement under rotational moment and the movement created by the passive elastic element 4 As a result of balancing with counter-moment, different stable angular velocity depending on the relative air velocity. This is accomplished through a structure that enables them to move to specific locations.

DETAILED DESCRIPTION OF THE INVENTION The invention is a vehicle exterior mirror assembly (1), designed to be attached to the vehicle body. a structured fixed carrier structure (2), on the said fixed carrier structure (2) at least one supported optical reflective element (3), the perimeter of the optical reflective element (3) must be at least The aerodynamic outer shell (4), which forms a part of the aerodynamic outer shell (4) has an angular 35 a joint axis (5) that enables its movement, aerodynamic outer shell (4) to the initial angle 6 at least one passive elastic element (6) and preferably an aerodynamic outer shell (4) that guides correctly It contains at least one damping element (7) that dampens its motion. Fixed support structure (2), directly attached to the vehicle body or via a support arm or mounting base (10) connected via and a fixed transport and positioning for the optical reflector element (3) It forms the region. The optical reflector element (3) is known as 5 according to the driver's vision needs. It can be adjusted via mechanical or electrical adjustment mechanisms and is adjusted. It can maintain its working position independently of the movement of the outer shell (4). In this context, the optical reflective element (3) being “fixed” means that the element in question cannot be fixed in any way This does not mean that the optical reflector element (3) cannot be adjusted by the driver. the determined viewing position, the aerodynamic outer shell (4) during operation 10 This means it is not affected by the angular movement it undergoes. The aerodynamic outer shell (4) encloses the entire perimeter of the optical reflector element (3) or a part of it. surrounding the part and interacting with the relative airflow (11) during the movement of the vehicle It includes external surfaces. The outer shell (4) is the one facing the forward direction of the vehicle's movement. a rounded front section and a rear section that allows airflow to be directed over the shell, 15 It may have top, bottom and / or outer side surfaces. The aerodynamic outer shell (4), optical reflective element (3) and fixed support structure (2) are the same. It is structured in such a way that it will not carry out the movement. Thus, the outer shell (4) is optically reflective. without changing the adjusted viewing position of the element (3) according to the fixed carrier structure (2). It is capable of independent angular movement. 20 The aerodynamic outer shell (4) has at least one bearing on the fixed support structure (2) or It is connected via the articulation region and has a limited angular range around the articulation axis (5). It is supported in a way that will enable movement. The articulated axis (5) can be positioned in the inner region of the outer shell (4) near the vehicle and In the preferred application, it generally extends in a vertical direction. However, 25 the axis of the joint (5), the mirror geometry of the vehicle and the intended direction of movement of the outer shell (4) Depending on the situation, it can also be arranged in a direction other than vertical. The position of the articulated axis (5) affects the aerodynamic force acting on the outer shell (4). A non-zero moment arm (14) is formed between line (13) and the joint axis (5). It is selected in the following way: 30 The movement of the outer shell (4) around the hinge axis (5), the starting position stopper (8) and The maximum angle is limited by the stopper (9). Starting position 7 stopper (8), outer shell (4) when the vehicle is stationary or at low relative air speeds When determining the starting angle, the maximum angle stopper (9) of the outer shell (4) is allowed It limits its maximum angular movement. Circular between the outer shell (4) and the optical reflective element (3) and / or fixed support structure (2) a movement gap (21) is left. This environmental movement gap (21) is left outside 5 mechanical with fixed elements during the movement of the shell (4) around the joint axis (5). It is sized to prevent contact from occurring. Passive elastic element (6) is located between the outer shell (4) and the fixed load-bearing structure (2) or between the outer shell. (4) It is located in an area close to the joint connection. Passive elastic element (6) will enable the outer shell (4) to return to its starting position. It creates an elastic countermoment. Elastic element (6); torsion spring, tension spring, compression spring, leaf spring, elastomeric element, flexible joint or one of these It can be done in combination with other methods. In the preferred application, the passive elastic element (6) is around the joint axis (5). It is a positioned torsion spring. One end of the torsion spring is on the fixed support structure (2), 15 The other end moves on or together with the aerodynamic outer shell (4) It is supported on a connecting element. The passive elastic element (6) is mounted to be pre-tensioned in the initial position. Thus, the outer shell (4) can be protected at low relative air speeds or when the vehicle is stationary. It is held towards the starting position stopper (8). 20 The pre-stress and elastic coefficient of the elastic element (6) cause the outer shell (4) to move. It can be selected to determine the aerodynamic moment threshold required for initiation. Damping element (7) is relative to the outer shell (4) and the fixed load-bearing structure (2) during movement. They are connected in a way that will generate movement. Damping element (7), outer shell (4) sudden air gusts, crosswind, turbulence, vehicle wake flow 25 or road vibrations limit its ability to move quickly back and forth. Damping element (7); rotary viscous damper, linear damper, friction damper, elastomeric damper, magnetic eddy current damper, or a combination thereof. This can be done in this way. 8 The connection points of the damping element (7) and the damping coefficient, the stable angular of the outer shell (4) will enable it to reach that location and reduce unwanted oscillations around that location. It can be selected in this way. When a vehicle moves, the outer shell changes shape as a result of the relative movement between the vehicle and the surrounding air. Relative airflow (11) occurs on (4). 5 Relative airflow (11) creates a variable pressure distribution on the outer surfaces of the outer shell (4). It creates. The resultant of the said pressure distribution on the outer shell (4), This is considered as the resultant aerodynamic force acting on the outer shell. The line of action of the resultant aerodynamic force (13), the geometry of the outer shell (4), the surface Depending on their slopes, the shape of their front and rear sections, and their position on the vehicle, 10 It is determined. The geometry of the outer shell (4) and the hinge axis (5) are affected by the resultant aerodynamic force. In fact, (13) will not pass through the joint axis (5), in other words, the effect there will be a non-zero moment arm (14) between the line (13) and the joint axis (5). It is arranged as follows. 15 moment between the line of action of the resultant aerodynamic force (13) and the hinge axis (5) The arm (14) has an aerodynamic moment of rotation around the joint axis (5) on the outer shell (4). It creates. Therefore, the movement of the outer shell (4) depends not only on the presence of airflow, but also on This depends on the position of the outer shell geometry and the hinge axis (5) relative to each other. 20 Magnitude and direction of the moment arm (14); surface geometry of the outer shell (4), joint axis This can be determined depending on the position of (5) and the direction of arrival of the relative airflow (11). The aerodynamic moment occurring on the outer shell (4) is the initial moment of the outer shell (4). When the outer shell (4) is in the direction that will cause it to move from its position, the joint axis (5) performs angular motion around it. 25 When the outer shell (4) starts to move, the passive elastic element (6) deforms and the outer an elastic countermoment is created which causes the shell (4) to return to its initial position It brings. The counteracting moment created by the aerodynamic moment on the outer shell (4) and the elastic element (6) The moments act in opposite directions. 30 9 At a given relative airspeed, the aerodynamic moment and the elastic countermoment must be equal to each other. An angular position is formed which is balanced by the relative position of the outer shell (4). The stable equilibrium angle for air velocity is defined as (16). In this working principle, the outer shell (4) consists of two that only operate between the starting and ending positions. not in the form of a fixed cover, but rather a 5-positioned balance between aerodynamic load and elastic counterload. It functions as a passive aerodynamic element that can change its position depending on the environment. A small deviation in the angle of the outer shell (4) at the stable equilibrium angle As a result, the difference between the aerodynamic moment and the elastic countermoment is the outer shell (4) It is arranged in such a way as to redirect to the stable equilibrium angle (16). As the relative airspeed of the vehicle increases, the aerodynamic force on the outer shell (4) and the related 10 Aerodynamic moment is generally increasing. When the aerodynamic moment becomes greater than the elastic countermoment, the external The shell (4) moves around the hinge axis (5) in the direction away from the starting position. is doing. As the angle of the outer shell (4) increases, the aerodynamic force distribution of the outer shell and the associated 15 The moment characteristic can also change. At the same time, the passive elastic element (6) As the deformation increases, the elastic countermoment also changes. As a result of these two effects, a new equilibrium angle is formed at a given relative air velocity. If the relative airspeed increases even further, the new aerodynamic load condition will be Another stable angular position can occur. Thus, the outer shell (4), vehicle 20 Changes in speed are detected by an external speed sensor, electronic control unit, or main motion controller. It can track mechanically without the use of an actuator. When the vehicle speed decreases, the aerodynamic moment decreases, and the counter moment of the elastic element (6) becoming dominant and the outer shell (4) to the starting position or lower speed condition It is moving back toward the corresponding stable position. 25 An important feature of the invention is the movement of the aerodynamic outer shell (4) to the optical reflective element. (3) does not change the direction of view. For this purpose, the optical reflector element (3) is supported on a fixed carrier structure (2) The aerodynamic outer shell (4) is separated from the optical reflector element (3) in terms of movement. Therefore, the outer shell (4) can be positioned in one or more different angular positions around the hinge axis (5). When the optical reflector element (3) passes, the driver’s vision is pre-set. It maintains its position. Thanks to this structure, the aerodynamic outer shell (4) adapts to aerodynamic conditions. The function of optical vision is distinguished from its purpose of operation. 5 Starting position stopper (8), outer shell (4) in low speed or stopping condition It determines the starting angle. Maximum angle stop (9) determined by the aerodynamic force of the outer shell (4). It prevents it from exceeding its maximum angular movement limit. Stoppers (8, 9), optical reflective element (3) throughout the range of motion of the outer shell (4), fixed 10 unwanted mechanical contact with the carrier structure (2), support arm (10) and / or vehicle body It is positioned in such a way that this will not happen. The circumferential movement gap (21) located between the outer shell (4) and the fixed elements, outside It also limits the contacts that may occur during the movement of the shell (4). The joint area, elastic element (6) and damping element (7) protect against external 15 such as water, ice, dust and road salt. In order to protect against environmental effects, it is partially or partially protected by a protective sealing element (15) It can be completely surrounded. In addition, secondary safety measures are in place to prevent the outer shell (4) from separating from the vehicle body. The connection (18) can be used. Secondary safety connection (18), flexible tie, wire, strip, pin or it can be implemented in the form of a similar limiting element. 20 Aerodynamic characteristics of the outer shell (4), outer surface geometry and hinge axis (5) Location is determined jointly. changing the line of action (13) of the resultant aerodynamic force on the outer shell (4) or Lips, fins, curved surfaces, recesses, and flow that affect the magnitude of the aerodynamic moment. Orientation surfaces or similar geometric structures may be present. 25 These geometric structures occur at different angular positions of the outer shell (4). It is able to enable a controlled change in aerodynamic moment. Thus, the angular position of the outer shell (4) has the desired characteristic according to the relative air velocity. It is possible to make changes. 11 In one application of the invention, the aerodynamic outer shell (4), the articulated axis (5), passive elastic element (6), damping element (7), starting position stopper (8) and maximum angle The stopper (9) together can form a modular outer shell unit (19). The modular outer shell unit (19) is connected to the existing fixed carrier structure (2). It can be attached to points (20) in a removable or replaceable manner. 5 In this way, different aerodynamic external structures are built on the same basic fixed optical core and carrier structure (2). shell geometries can be used and the aerodynamic behavior of the outer shell (4) of the vehicle depending on the model, mirror geometry, or targeted operating speed range It can be changed. Local airflow around the exterior rearview mirrors on the right and left sides of the vehicle is 10 Since the aerodynamic geometries of the right and left outer shells (4) can be different from each other and / or passive elastic elements (6) pre-stresses can be selected differently from each other. Thus, both outer shells have different aerodynamic characteristics corresponding to the local aerodynamic conditions on their respective sides. It can reach stable equilibrium angles (16). Working principle 15 In the invention device, the aerodynamic outer shell (4) is used when the vehicle is stationary or at low speed. It is held in its initial position by the pre-tension of the passive elastic element (6). When the vehicle starts moving, the relative airflow (11) on the outer shell (4) This creates an aerodynamic pressure distribution, resulting in a resultant aerodynamic force. It occurs. 20 Due to the geometry of the outer shell (4) and the relative position of the hinge axis (5), the resultant moment arm (14) between the line of action of the aerodynamic force (13) and the joint axis (5) This moment arm creates an aerodynamic rotational moment on the outer shell (4). It brings. The aerodynamic moment of rotation will displace the outer shell (4) from its initial position by 25 When it reaches a sufficient level, it counteracts the moment of the passive elastic element (6) externally It enables the shell (4) to rotate around the joint axis (5). Deformation of the passive elastic element (6) and associated counter moment as the outer shell (4) rotates. is changing; at the same time the aerodynamic force distribution and moment of the outer shell (4) Its characteristics are also changing. 30 12 The outer shell (4) is at the point where the aerodynamic moment and the elastic countermoment are equal. A stable equilibrium angle (16) is formed for. Since the aerodynamic moment on the outer shell (4) changes with the change in vehicle speed, The outer shell (4) is in a new stable angular position corresponding to the new aerodynamic load condition. It is heading in that direction. 5 During this movement, the optical reflector element (3) is adjusted on the fixed carrier structure (2). Since the driver's field of vision is maintained, the aerodynamic adaptation of the outer shell (4) ensures the driver's field of vision. It does not fundamentally change its direction. Due to sudden wind gusts or turbulence, the outer shell (4) moves rapidly around the stable angle. If it moves, the damping element (7) limits the movement and the outside 10 It helps the shell (4) to settle into its new equilibrium position in a controlled manner. When the vehicle speed decreases, the aerodynamic moment on the outer shell (4) decreases and passive The counter moment of the elastic element (6) to the outer shell (4) to the starting position or lower speed It directs towards the location corresponding to the condition. Thanks to this working principle, the outer shell (4) can be used with any main electric actuator 15 or without requiring continuous electronic control, to the relative airflow to which the vehicle is exposed It is mechanically adaptable. In this design of the invention, the generation of motion depends not only on the presence of aerodynamic force; the geometry of the aerodynamic outer shell (4), the position of the hinge axis (5), the aerodynamic force The line of action (13), the moment arm (14) and the counter moment of the passive elastic element (6) 20 It is based on mechanical equilibrium, which is determined by the combination of its characteristics. Therefore, instead of the outer shell (4) moving to a single predetermined aerodynamic position, depending on the instantaneous balance of the aerodynamic load and the elastic counterload generated during operation It can assume different stable angular positions at different relative air velocities. The scope of protection for this application is defined in the claims section and is explicitly mentioned above in section 25. The examples given cannot be limited to those that a technically skilled person demonstrates in the invention. the innovation introduced can be created by using similar structures and / or this It is clear that this structure can be applied to other areas with similar purposes using the same technique. Therefore, such structures foster innovation and, in particular, surpass the known state of technology. It is also obvious that it will lack the criterion. 30
