The present disclosure relates to a mounting system for mobile devices in a vehicle. More particularly, the present disclosure relates to a mounting system that cools a mobile device when mounted in a vehicle.
Mobile devices and automotive vehicles are in common use. Due to frequent usage demands of mobile devices both during and outside of use within a motor vehicle, the ability to charge a mobile device within a vehicle is a common feature included in motor vehicles, either as part of an integral charging provided with the vehicle to consumers, or as an aftermarket feature sold separately and installed by the user or a technician.
Mobile devices may be charged in automotive vehicles via a USB cable or other cable that connects to the charging port of the mobile device, with the cable typically being plugged into a USB port of the vehicle, or plugged into a USB adapter that is plugged into a corresponding power port provided in the vehicle.
Mobile devices may also be charged in vehicles via wireless charging, a common standard of which is the Qi wireless charging standard, which is compatible with a number of smartphone and mobile device models.
Mobile device usage generates heat during use, which can be undesirable to the user. Temperature increases in mobile devices can also be detrimental to the life-span of the device, having detrimental results on the battery life and other components housed within the device. Heat can also be generated at a greater rate when the device is under heavy usage, which can often occur during vehicle use, such as when using navigation applications. For instance, during use of a navigation application, the device may be constantly downloading maps and traffic data. Additionally, the application may require that the screen remain illuminated to display the information generated by the app to aid the user in navigation. Mobile device usage increases when the screen is on, causing increased battery drain and heat generation.
Heat is also generated during the charging of the device, in addition to during the use of the device. Due to power demands of applications such as navigation applications as well as other applications frequently used during vehicle use, it may be desirable to keep the device in a charging state, to prevent the device from a drained battery condition at the conclusion of vehicle use.
While both wired charging and wireless charging are possible for many mobile devices, in many cases higher currents flow during wireless charging. The higher currents, combined with higher losses commonly associated with wireless charging, the warming of the device may be higher for wireless charging. Wireless charging may be more desirable for users in a vehicle, due to the increased convenience and elimination of a wire running between the device and a location on the console, which tethers the device to the vehicle. In many cases, the wire may need to be unplugged and re-plugged to the charging cable in order to use the device and can be inconvenient to constantly re-plug the device, and in many cases the device will remain unplugged.
In view of the foregoing, there remains a need for improvements to mobile device mounting systems in vehicles.
A system for mounting and cooling a mobile device in a vehicle is provided. The system includes a mounting structure disposed within a vehicle cabin and the mounting structure includes a base surface. A supplemental air outlet is disposed adjacent the base surface of the mounting structure. A supplemental passageway is in fluid communication with the supplemental air outlet and in fluid communication with a source of forced air from a vehicle HVAC system. Forced air from the vehicle HVAC system flows through the supplemental passageway and out of the supplemental air outlet for cooling a mobile device when the mobile device is retained by the mounting structure.
In one aspect, the base surface includes a plurality of nubs projecting from the base surface, the nubs configured to space the mobile device away from the base surface.
In one aspect, the mounting structure defines a recess in which the mobile device is received and the mobile device is securable within the recess.
In one aspect, the mounting structure includes a flap having an open position for allowing air to flow through the supplemental air outlet and a closed position for preventing air flowing from flowing through the supplemental air outlet.
In one aspect, the flap is biased toward the closed position.
In one aspect, the flap includes a projection extending therefrom in a direction opposite a direction of insertion of the mobile device.
In one aspect, insertion of the mobile device onto the mounting structure causes the flap to move from the closed position to the open position, and removal of the mobile device from the mounting structure causes the flap to move from the open position to the closed position.
In one aspect, the supplemental passageway includes an internal flap moveable between an open position and a closed position, wherein air from the HVAC system is blocked from entering the supplemental passageway when the internal flap is closed.
In one aspect, a wireless charging mechanism is disposed adjacent the base surface.
In another aspect, a method for cooling a mobile device in a vehicle is provided. The method includes mounting a mobile device to a mounting structure disposed within a vehicle cabin and providing forced air from a vehicle HVAC system through a supplemental passageway within the vehicle. The supplemental passageway is in fluid communication with a supplemental air outlet disposed adjacent the mounting structure.
The method further includes forcing the forced air out of the supplemental air outlet and into contact with the mobile device when the mobile device is mounted to the mounting structure. The method also includes, in response to contacting the mobile device with the forced air, cooling the mobile device.
In one aspect, the method includes in response to mounting the mobile device, automatically opening the supplemental air outlet to provide fluid communication between the supplemental passageway and the mobile device via the supplemental air outlet.
In one aspect, the method includes removing the mobile device from the mounting structure and, in response thereto, automatically closing the supplemental air outlet.
In one aspect, the mounting structure includes a base surface having a plurality of nubs projecting therefore, and the method includes forcing air between the base surface and the mobile device and around the nubs.
In one aspect, the method includes blocking air from entering the supplemental passageway when a temperature of the forced air is above a predetermined level.
In one aspect, the mounting structure includes a wireless charging mechanism, and the method includes wirelessly charging the mobile device.
Other advantages of the present invention will be readily appreciated, as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
Referring to
The mounting structure 12 is configured to secure a mobile device 20 thereto. The mounting structure 12 includes the wireless charging unit 18, which may be integrated into the structure of the mounting structure 12. Accordingly, when secured to the mounting structure 12, the mobile device 20 will therefore be charged via the wireless charging capability of the wireless charging unit 18 if the mobile device 20 includes wireless charging capability.
In one approach, the mounting structure 12 may include surrounding structure 12a, which may be in the form of arms (not shown) that are configured to grasp the mobile device 20 and secure the mobile device 20 in place relative to the mounting structure 12. The arms may be moveable into and out of engagement with the mobile device 20. The surrounding structure 12a may also be in the form of a band or snap-fit type structure, or may be in the form of a casing that leaves space around the mobile device 20. It will be appreciated that other forms of securing the mobile device 20 in place may also be used.
With reference to
The mounting structure 12 may alternatively, or additionally, include a magnetic element (not shown) disposed on or within the base surface 12b. The magnetic element may be configured to cooperate with corresponding magnetic material of the mobile device 20, thereby utilizing the cooperating magnetic properties of the device 20 and the mounting structure 12 to retain the mobile device 20 on the mounting structure 12.
In the case where the magnetic element is used, the surrounding structure 12a may be excluded from the mounting structure 12, with the retention being accomplished primarily by the magnetic element. However, it may alternatively be desirable to use the securing abilities of both the magnetic element and the surrounding structure 12a to secure the mobile device 20 to the mounting structure 12.
It will be appreciated that other securement mechanisms may be utilized that assist in retained the mobile device 20 to the mounting structure 12. For instance, a surface of the mounting structure may include a “sticky” or “tacky” coating or material that increases the friction between the mobile device 20 and the mounting structure 12. In another aspect, the mounting structure may include one portion of a cooperating structure system, such as hook-and-loop, with the mobile device 20 including the corresponding portion. In another aspect, the mounting structure 12 may include a cutout that corresponds to a protrusion that extends from the mobile device 20. In another aspect, the mounting structure 12 may include one or more suction devices.
The mounting structure 12 and the base surface 12b may include the wireless charging unit 18 fixed thereto. The wireless charging unit 18 may be fixed to the mounting device 12 in a position that will place the wireless charging unit 18 in close proximity to the mobile device 20 when the mobile device is secured to the mounting device 12.
In one approach, the wireless charging unit 18 may be integrated into a body portion of the mounting structure 12, below or embedded into the base surface 12b. In another approach, the charging unit 18 may be a separate component that is affixed or attached to the base surface 12b and configured to be disposed between the mobile device 20 and the base surface 12b when the mobile device 20 is held on the mounting structure 12. In another aspect, the charging unit 18 may be a separate structure and disposed behind the base surface 12b, such that the base surface 12b is disposed between the mobile device 20 and the charging unit 18.
The wireless charging unit 18 may be disposed across substantially the entire base surface 12b of the mounting unit 12, as shown in
The mounting structure 12 may also include a non-slip coating, such as a rubber or elastomeric material that may improve the grip of the mounting structure 12. In one approach, the mounting structure 12 and the base surface 12b thereof may be oriented such that the mobile device 20 may lay generally flat on the base surface 12b, such that the non-slip coating will frictionally retain the mobile device 20 in place and prevent or otherwise limit sliding of the mobile device 20 in response to vehicle maneuvers.
The mounting structure 12 is configured to be disposed adjacent an area of the vehicle interior where the mounting structure 12 may be exposed to cooling air provided by the vehicle HVAC system 16.
The mounting structure 12 may be integrated into the interior structure of the vehicle 15, such as a vehicle console 30 typically in front of the vehicle driver and within reaching distance of the driver. The mounting structure 12 may be formed, at least partially, in the structure 14 used for the vehicle console 30. It will be appreciated that mounting structure 12 may also be disposed near other occupants of the vehicle, such as the passenger seat adjacent the driver, or in other locations of the vehicle where cooling outlets are disposed, and that the reference to the driver and the vehicle console are one example.
The HVAC system 16 of the vehicle includes a plurality of air outlets 32 disposed at different locations across the vehicle console 30. The air outlets 32 may include a mechanism for selectively opening and closing the air outlets 32. The air outlets 32 are configured to provide forced air into the vehicle cabin to provide heating or cooling to the vehicle cabin as is typical.
In one approach, the mounting structure 12 may be arranged on the vehicle console 30 adjacent the openings defined by the air outlets 32. For example, as shown in
With reference to
The wireless charging unit 18 may be disposed adjacent the supplemental air outlet 38. For example, the wireless charging unit 18 may be disposed around the supplemental air outlet 38, above or below the supplemental air outlet 38, or to the side of the supplemental air outlet 38, so long as the wireless charging unit 18 is disposed close enough to the mobile device 20 when the mobile device 20 is secured by the mounting structure 12.
In one approach, the system 10 may not include a wireless charging unit. Wireless charging is typically an additional feature provided on many mobile devices 20, but not all mobile devices include the ability to be charged wirelessly. Most mobile devices may also be charged by a charging cable configured to cooperate with the charging port of the particular mobile device. In the case of the system 10 not including a wireless charging unit, the mounting structure 12 may still retain the mobile device 20 in a position adjacent the supplemental air outlet 38, with device charging being provided by a charging cable compatible with the mobile device 20. The system 10 may still include the mobile charging unit 18, even if the mobile device 20 does support wireless charging, with the wireless charging unit 18 simply going unused.
As shown in
In one form, the flap 40 may be made from a flexible and resilient material, having a nominal position that corresponds to a closed position, such that the flap 40 is biased toward the closed position. The flap 40 may have various forms that will open in response to placing the mobile device 20 on the flap. For example, the opening mechanism of the flap 40 may be in the form of a rotationally symmetric nub which opens orifices when a force is applied on the nub, or the flap 40 may include a living hinge that is configured to permit the flap 40 to pivot in response to a force exerted against the bias. The flap 40 may alternatively be configured to include a mechanical hinge with a spring bias or other biasing mechanism that biases the flap 40 into the closed position. The flap 40 may be in the form of a single flap 40, or may be in the form of a multi-piece flap, with each piece having hinge functionality to allow the flap to open and to return the flap 40 to the closed position. In another aspect, the flap 40 may be in the form of a poppet-type mechanism.
The mounting structure 12 may define a recess 42 into which the mobile device 20 may be placed. The base surface 12b may be at the bottom of the recess 42, and the base surface may be at least partially defined by an outer surface of the flap 40.
The flap 40 may include one or more projections 44 that may have a height within the recess 42 generally corresponding to the depth of the recess 42. Accordingly, when the mobile device 20 is not disposed within the recess 42, the projection 44 does not project beyond the opening of the recess 42, such that the projection 44 will not project out of the recess 42. In another approach, the projection 44 may project out of the recess, or may project to a height that is inward from the opening of the recess 42. It will be appreciated that different heights of the projection 44 may affect the degree to which the flap 40 is opened. However, the degree to which the flap 40 opens may also depend on the extent to which the mobile device 20 is inserted into the recess 42. The height of the recess 42 and the height of the projection 44, and the relative height between them, may vary according to design needs and the ever-changing shapes and designs of mobile devices.
The height of the projection 44 is configured to be large enough such that when the mobile device 20 is seated in the mounting structure 12, the back of the mobile device 20 will force the projection 44 down toward the supplemental passageway 36, such that the flap 40 will move sufficiently inward into the supplemental passageway 36 to create an opening for forced air to flow through the supplemental air outlet 38. The flap 40 need not open fully for forced air to be able to escape through supplemental air outlet 38 and to contact the mobile device.
With reference to
In one approach, the mounting structure 12 may include a plurality of nubs 46 that project from the base surface 12b outwardly in a direction toward the mobile device 20. The nubs 46 may be generally evenly distributed over the base surface 12b, including the outward facing surface of the flap 40. The nubs 46 may be in the form of spikes or dimples or the like. The outer tips of the nubs 46 will contact the facing surface of the mobile device 20 when the mobile device 20 is placed in the mounting structure 12, as shown in
The nubs 46 may be distributed in a generally even distribution with consistent spacing, or may be distributed with a variable spacing. In one aspect, the nubs 46 may be more densely distributed in the middle of the recess 42 relative to the perimeter of the recess 42. In one aspect, the nubs 46 may be more densely distributed at the perimeter. In one aspect, the nubs 46 may have the same size and shape. In another aspect, the nubs 46 may have different sizes and/or shapes. In one aspect, the nubs 46 may be arranged and or sized/shaped randomly across the recess 42.
During operation of the HVAC system 18, the forced air provided by the HVAC system 18 may flow through the various passageways 36 to provide cool air or warm air into the vehicle cabin, depending on the heating/cooling desires of the user. In instances where the air conditioning is operating to cool the vehicle, the cool air provided by the HVAC system 18 can advantageously be diverted or provided into the supplemental passageway 38, where the air will operate to cool the mobile device 20 when the mobile device 20 is disposed in the mounting structure 12 and the flap 40 is closed.
When the mobile device 20 is removed from the mounting structure 12 and the flap 40 is closed, the cooled air that is provided into the device air passageway 36 may be blocked by the flap 40, such that the cooled air will not exit through the supplemental air outlet 38. Accordingly, the cooled air may be efficiently re-routed into other passageways in the HVAC system 18, where it may exit through one of the other air outlets 32 to cool the vehicle cabin as desired. However, in general, the passageway 36 and the air flow into and potentially back out of the passageway 36 when the outlet 38 is closed will not significantly affect the other outlets and passageways of the HVAC system.
In one approach, the device air passage 36 may include an internal flap 48 disposed on the device air passageway 36 that may operate to block the supplemental passageway 36. It may be desirable to block the supplemental passageway 36 when cool air is not being provided, or when hot air is being provided during a heating operation of the HVAC system 18. The internal flap 48 may operate similar to other internal flaps of known HVAC systems, which control which passageways and vents can receive and output the forced air depending on the desires of the user. For example, in a defrost mode, forced air may be directed toward the windshield, or forced air may be directed toward the driver's feet in other instances. Thus, in response to a demand for cabin heating, the internal flap 48 may be closed, to limit additional hot air from reaching the mobile device 20, which can affect the cooling. In another aspect, the HVAC system may be arranged such that only cool air can reach the outlet 38.
However, it will be appreciated that the internal flap 48 may be excluded, even in instances where warm/hot air is being provided. In some cases, the convection provided by the flowing air across the mobile device 20 is sufficient to reduce the heat of the mobile device 20, even in instances where the air being provided is warm. Even if the air is hotter than the device 20, the air flow may still cool the device 20 due to the convection provided by the airflow, if the surrounding air combines with the warmer air being provided to produce an air temperature that is approximately the same or lower than the temperature of the device surface. It will be appreciated that even if the combined air temperature is higher than the device 20, an increase in the surface temperature of the device 20 will be limited to the combined air temperature, and if the device 20 subsequently heats to a temperature higher than the combined air temperature, the device 20 will thereafter be cooled, because the combined air temperature will then be less than the temperature of the device 20. However, typically, the temperature of the warm air provided by the HVAC system 16 will still be less that the temperature of the mobile device 20 in an overheated or highly heated state, and therefore even warm air provided by the HVAC system 16 can still cool the device 20 from an overheated state, and may still provide device cooling benefits relative to an overheated mobile device 20 that is disposed in relatively stagnant air.
The above description has referred to mobile devices 20 that are being charged while mounted to the mounting structure 12. It will be appreciated that the cooling functionality will still be provided even when the mobile device 20 is not plugged in or receiving power from a wireless charging unit 18 or other charging mechanism. The benefits of cooling the device 20 are still present if the device 20 is not charging, because the device 20 may generate heat and benefit from cooling simply by being turned on and/or in use. In some cases, the user may be provided with a toggle feature than can turn off the wireless charging unit 18, similar to unplugging the charging cable. This may be desirable when the device 20 is fully charged or nearly fully charged, in which the user may wish to prevent over-charging of the device 20.
The above description therefore provides for a simple and cost-effective system for mounting a mobile device 20, such as a smartphone or tablet or similar device, to vehicle structure, which allows for cooling of the device 20 in addition to charging of the device 20 when mounted.
A method for cooling the mobile device 20 is also provided by the description herein. The method includes installing a mobile device 20 on the mounting structure 12 of the vehicle. The method also includes providing forced air from the HVAC system 18 directly to the mobile device 20, such that the forced air contacts the mobile device 20 and cools the mobile device. The method 20 may also include opening the supplemental air outlet 38 in response to attaching the device 20 to the mounting structure, and may also include closing the supplemental air outlet 38 in response to removing the mobile device 20 from the mounting structure 12. The supplemental air outlet 38 may be closed automatically. The method also includes charging the mobile device 20 during the cooling operation. The mounting structure 12 may include the wireless charging unit 18, or the charging power may be provided by a charging cable.
Obviously, many modifications and variations of the present invention are possible in light of the above teachings and may be practiced otherwise than as specifically described while within the scope of the appended claims. These antecedent recitations should be interpreted to cover any combination in which the inventive novelty exercises its utility.
