Embodiments of the present disclosure relate to a selectively repositionable spotter mirror for a mirror system and a method of making and using the same. All vehicles utilize external rear view mirrors to visualize an area along the side of or behind the vehicle and to fulfill mandatory legal field of view requirements. In some cases, the external mirrors include an additional spotter mirror or spotter glass that functions to help an operator of the vehicle visualize and see objects in a blind zone or blind spot area behind the operator. In vehicles equipped with the additional spotter glass, the external mirrors are adjustable, and any adjustment of the external mirror causes a corresponding adjustment in the spotter glass.
Systems, methods, and apparatuses for a mirror assembly are shown and described. In one embodiment, a mirror assembly for a vehicle includes a housing configured to be coupled to the vehicle, a primary mirror assembly, and a secondary mirror assembly selectively repositionable independent of the primary mirror assembly. The primary mirror assembly includes a primary mirror configured to provide a reflection showing a primary field of view and a first base member coupled to the primary mirror and adjustably coupled to the housing. The secondary mirror assembly includes a secondary mirror configured to provide a reflection showing a secondary field of view and a second base member coupled to the secondary mirror. The second base member is pivotable about a point relative to the first base member such that the secondary mirror is adjustable relative to the primary mirror.
In another embodiment, a mirror assembly for a vehicle includes a housing configured to be coupled to the vehicle a primary mirror assembly, a secondary mirror assembly selectively repositionable independent of the primary mirror assembly, and an actuator coupled to the primary mirror assembly. The primary mirror assembly includes a primary mirror configured to provide a reflection showing a primary field of view and a first base member coupled to the primary mirror and adjustably coupled to the housing. The secondary mirror assembly includes a secondary mirror configured to provide a reflection showing a secondary field of view and a second base member coupled to the secondary mirror. The second base member is pivotable about a point relative to the first base member such that the secondary mirror is adjustable relative to the primary mirror. The actuator is configured to selectively reposition the primary mirror assembly relative to the housing in response to a user input. The secondary mirror assembly is configured to be manually repositionable relative to the primary mirror assembly.
In yet another embodiment, a mirror assembly for a vehicle includes a housing configured to be coupled to the vehicle a primary mirror assembly, and a secondary mirror assembly selectively repositionable independent of the primary mirror assembly. The primary mirror assembly includes a primary mirror configured to provide a reflection showing a primary field of view and a first base member coupled to the primary mirror and adjustably coupled to the housing. The secondary mirror assembly includes a secondary mirror configured to provide a reflection showing a secondary field of view and a second base member coupled to the secondary mirror such that the secondary mirror assembly is repositioned relative to the housing whenever the primary mirror assembly is repositioned relative to the housing. The second base member is pivotable about a point relative to the first base member such that the secondary mirror is adjustable relative to the primary mirror.
These and other features, together with the organization and manner of operation thereof, may become apparent from the following detailed description when taken in conjunction with the accompanying drawings.
Referring to the Figures generally, systems, methods, and apparatuses for a selectively repositionable spotter mirror are shown.
When driving a vehicle, it is desirable to be aware of the vehicle's surroundings. One area that causes particular difficulty is a blind spot of the vehicle. Blind spots are typically unique to every vehicle and operator combination. For example, for a single vehicle, different operators having different height percentiles (e.g., 25th percentile vs. 75th percentile of height) may have different blind spots. Further, vehicles often have seats which are adjustable. With adjustable seats, the blind spots that a particular operator experiences are likely to be unique to that specific operator. In order to assist operators in visualizing blind spots, some cars have side mirror assemblies which include a primary mirror and a spotter mirror that aids in blind spot visualization. The spotter mirrors are typically in the corner of the mirror assembly and offer a different reflected field of view to the operator than the primary mirror. Spotter mirrors are often integral with the mirror, and cannot be adjusted independent from the mirror. As a result, the operator is often left with deciding between adjusting the mirror assembly to utilize either the spotter mirror or the primary mirror. Often, when the operator decides to utilize the primary mirror, the spotter mirror cannot be properly utilized by the operator. This largely prohibits the spotter mirror from enabling the operator to visualize or to see objects in the blind spots.
According to the present disclosure, a mirror system includes a primary mirror assembly and a secondary mirror assembly. The primary mirror assembly may be moveable such that an operator can see an area along the side of a vehicle. The secondary mirror assembly may be moveable independent of the primary mirror assembly such that the operator can see a different area than can be seen in the primary mirror assembly. For example, the secondary mirror assembly can be used to focus on an area corresponding to a blind spot or an area behind the vehicle. In some embodiments, when the secondary mirror assembly is adjusted, the primary mirror assembly is not adjusted. Both the secondary mirror assembly and the primary mirror assembly may be electronically or manually selectively repositioned independent of each other and with respect to each other.

In some embodiments, a similar arrangement to the frame 270, coupler 260, and adaptor 252 arrangement discussed herein is used to couple primary mirror assembly 110 to housing 132.
Referring to
In other embodiments, one or both of primary actuator 520 and secondary actuator 530 are omitted, and primary mirror assembly 110 and/or secondary mirror assembly 120 are instead repositioned manually (e.g., by an operator applying a force or torque directly on primary mirror assembly 110 or secondary mirror assembly 120). Accordingly, primary mirror assembly 110 and secondary mirror assembly 120 may each be either manually repositioned or repositioned using an actuator.
Secondary mirror assembly 120 may be configured to maintain an orientation relative to primary mirror assembly 110 until secondary mirror assembly 120 experiences a threshold torque, either applied directly or created by a force offset from center of rotation 906. Friction between frame 270, coupler 260, and adaptor 252 prevents secondary mirror assembly 120 from moving until the threshold torque overcomes the friction. The threshold torque may be applied by an operator, by an actuator, or by another source. A similar mechanism may couple primary mirror assembly 110 to housing 132 such that primary mirror assembly 110 is configured to maintain an orientation relative to housing 132 until primary mirror assembly 110 experiences a threshold torque.
Processor 504 may be implemented as a specific purpose processor, an application specific integrated circuit (ASIC), one or more field programmable gate arrays (FPGAs), a group of processing components, or other suitable electronic processing components. Memory 506 is one or more devices (e.g., RAM, ROM, flash memory, hard disk storage) for storing data and computer code for completing and facilitating the various user or client processes, layers, and modules described in the present disclosure. Memory 506 may be or include volatile memory or non-volatile memory and may include database components, object code components, script components, or any other type of information structure for supporting the various activities and information structures of the inventive concepts disclosed herein. Memory 506 is communicably connected to processor 504 and includes computer code or instruction modules for executing one or more processes described herein.
In some embodiments, mirror system 100 includes an actuator (e.g., primary actuator 520 or secondary actuator 530) configured to selectively reposition mirrored insert 220. For example, secondary actuator 530 may include a series of linear actuators extending between frame 270 and coupler 260 or spotter base member 240. Extension or retraction of the linear actuators rotates coupler 260 relative to frame 270. By way of another example, primary actuator 520 may include a series of linear actuators extending between housing 132 and mirror base member 210. Extension or retraction of the linear actuators rotates primary mirror assembly 110 relative to housing 132 about a point. By way of yet another example, the secondary actuator 530 includes a gear mechanism coupled to the frame 270 and configured to interface with spotter base member 240 to rotate mirrored insert 220. In other embodiments, one or both of the actuators are omitted and the mirror assemblies are articulated or repositioned manually by an occupant of the vehicle (e.g., the operator, etc.). In these embodiments, friction between the various components facilitates selective manual repositioning of the mirrored inserts relative to housing 132. In either case, mirrored insert 200 and/or mirrored insert 220 may be set to a variety of different orientations. Due to the coupling between frame 270, coupler 260, and adaptor 252, mirrored insert 220 is adjustable to an infinite number of orientations. For each pair of orientations of mirrored insert 220, mirrored insert 220 can be moved to another orientation between the pair, resulting in the infinite number of orientations. Accordingly, secondary mirror assembly 120 is reconfigurable into an infinite number of orientations relative to primary mirror assembly 110, as opposed to having only a finite number of relative orientations.
In some embodiments, the movement of secondary mirror assembly 120 is intentionally restricted. In these embodiments, the movement of secondary mirror assembly 120 may be restricted structurally through frame 270, coupler 260, adaptor 252, or another component of mirror system 100. By way of example, coupler 260 may be restricted from rotating about axis 900. As shown in
According to various embodiments, secondary mirror assembly 120 is located on an outboard (e.g., opposite vehicle 140) side of mirror system 100. In other embodiments, secondary mirror assembly 120 is located on an inboard (e.g., proximate vehicle 140) side of mirror system 100. In some embodiments, secondary mirror assembly 120 is located on a top side of mirror system 100. In other embodiments, secondary mirror assembly 120 is located on a bottom side of mirror system 100. It is understood that secondary mirror assembly 120 can be located at any location and be of any size compared to mirror system 100. The operator of vehicle 140 may adjust primary mirror assembly 110 and/or secondary mirror assembly 120 depending on a seating location in vehicle 140. For example, if the operator moves the operator's seat of vehicle 140, the operator may correspondingly adjust secondary mirror assembly 120. According to various embodiments, input/output interface 510 includes a first set of electronic controls (e.g., levers, knobs, etc.) configured to control primary mirror assembly 110 and a second set of electronic controls configured to control secondary mirror assembly 120. The memory 506 may be configured to store a preset position of primary mirror assembly 110 and/or secondary mirror assembly 120, in some cases for a particular operator. The presets may be selectable by an operator in vehicle 140. When the operator selects a preset, controller 502 may command primary actuator 520 and/or secondary actuator 530 to move the corresponding mirror assembly to a position stored in memory 506. In this way, vehicle 140 can easily adjust a position of the mirror assemblies for different operators in a short amount of time.
In various applications, mirrored insert 200 and mirrored insert 220 are constructed from mirrored glass. In other applications, mirrored insert 200 and mirrored insert 220 are constructed from mirrored plastic or polymer. In still other embodiments, mirrored insert 200 and mirrored insert 220 are constructed from a similar mirrored material. According to various embodiments, mirrored insert 220 has a convex shape. In some embodiments, mirrored insert 200 has a flat or planar shape. Mirrored insert 220 may be coupled to support insert 230 through the use of an adhesive, such as glue or double-sided tape. In an alternative embodiment, mirrored insert 220 is encapsulated in support insert 230 (e.g., through a molding process, etc.).
According to various embodiments, secondary mirror assembly 120 is replaceable and serviceable. For example, in some embodiments, secondary mirror assembly 120 is removed by removing fasteners 290 and removing coupler 260 from spotter base member 240. Similarly, individual components of secondary mirror assembly 120, such as frame 270, may be serviced and replaced. For example, once secondary mirror assembly 120 is removed from mirror system 100, frame 270 may be removed from secondary mirror assembly by removing support insert 230 and mirrored insert 220, and then removing fastener 280. In this way, various components of secondary mirror assembly 120 can be replaced and serviced.
In some embodiments, secondary mirror assembly 120 does not include support insert 230 and spotter base member 240 receives mirrored insert 220 directly. In one embodiment, support insert 230 has a convex shape and mirrored insert 220 has a matching convex shape. In other embodiments, mirrored insert 220 is flexible and support insert has a convex shape such that mirrored insert 220 forms around support insert 230 when installed in secondary mirror assembly 120.
According to various embodiments, any of mirror system 100, primary mirror assembly 110, and secondary mirror assembly 120 may be heated (e.g., in a de-frost mode) and may contain lights (e.g., driving lights, directional lights, proximity awareness lights, security lights, alarm lights, etc.). By way of example, support insert 230 may include an electrical heating element configured to emit thermal energy into secondary mirror assembly 120. The primary mirror assembly 110 and secondary mirror assembly 120 may both or either be magnified or tinted depending on an application of mirror system 100. Further, the shape, size, and configuration of any of mirror system 100, primary mirror assembly 110, and secondary mirror assembly 120 may be altered depending on an application of mirror system 100. Similarly, any of mirror system 100, primary mirror assembly 110, and secondary mirror assembly 120 may be set to positions automatically by control system 500. Memory 506 may store presets or instructions for particular orientations and configurations of primary mirror assembly 110 and secondary mirror assembly 120.
Mirror system 100 may be utilized by a variety of vehicles. For example, mirror system 100 may be utilized by trucks, delivery trucks, delivery vans, refuse trucks, construction vehicles, agricultural vehicles, emergency vehicles, military vehicles, cars, race cars, competition vehicles, motorcycles, mopeds, scooters, bicycles, aircraft, and other vehicles.
