Description

[Technical field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates generally to vehicles, and more particularly to an electric roll-up truck bed cover for covering a truck bed. [Background technology]

[0002] Vehicles are useful in a variety of ways, including the ability to store and transport cargo. For example, trucks (such as pickup trucks) have truck beds that are useful for storing and transporting such cargo.

[0003] However, many trucks on the market today have open truck beds that are uncovered and exposed to the surrounding environment. Without a cover over the truck bed, cargo stored or transported in the truck bed is vulnerable to weather conditions and potential security issues related to, for example, theft. The cargo can be damaged by rain, snow, and even wind, and without a cover, the cargo is in full view and may be exposed to theft.

[0004] To mitigate the possibility of such damage, many truck owners install aftermarket truck bed covers to cover the bed of their trucks. However, such aftermarket truck bed covers are not only difficult to install, but may not precisely fit the specifications of the truck bed of different models of trucks. If the truck bed cover does not precisely fit, rain or snow may get in through gaps between the truck bed cover and the surrounding walls of the truck bed, causing damage to the cargo. Furthermore, many aftermarket truck bed covers are not only difficult to install and difficult to use, but also take up space in the truck bed, reducing the overall usefulness of the truck.

[0018] The present disclosure may be understood by reference to the following detailed description: It should be noted that for clarity of illustration, certain elements in the various drawings may not be drawn to scale, may be represented diagrammatically or conceptually, or may not precisely correspond to particular physical configurations of the embodiments.

[0019] Embodiments of the present invention generally relate to an automated truck bed cover configured to roll down onto a truck bed and cover any stored contents. In one embodiment, the truck bed is known as a "tonneau" and the truck bed cover is a "tonneau cover." As described in more detail below, the tonneau cover may be constructed from a series of movable rigid slats with seals between each slat such that when fully extended onto the truck bed, the entire cover is relatively weatherproof. In one embodiment, the cover is retracted to a rolled up configuration and stored within a compartment under the truck adjacent the connection between the cab and the bed. In use, an electric motor is used to extend or retract the roll-up cover onto the truck bed.

[0020] In use, the edges of each slat making up the cover have one or more rollers that slide along parallel grooves that extend between the cab and the bed and then along the top edge of the bed. The rollers are guided along these grooves from underneath the truck to above the truck bed as the cover is extended and retracted. This arrangement will be more readily understood with reference to the drawings and description that follow.

[0021] In one embodiment, the truck bed cover is made from a series of parallel rigid slats connected to each other via a flexible and watertight linkage. The slats may be about 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100 millimeters wide or more and may have a length that extends from one side of the truck bed to the other. The length may be, for example, 1200, 1300, 1400, 1500, 1550, 1575, 1600, 1625, 1700, 1800, 1900 millimeters or more. In one embodiment, the slat width is about 50 mm and the slat length is about 1600 mm. In one embodiment, there are one or more rollers at each end of each slat configured to fit into a series of "U" or "V" shaped grooves attached to the top of the side of the truck bed. As an electric motor that winds and unwinds the cover is engaged, a roller attached to each slat rolls along the inside of the groove to cover the truck bed. To reduce noise such as rattle when the cover is extended or retracted and when the truck is driven over the road, each roller may be biased to remain firmly pressed against one side of the groove by a flexible strip that applies pressure to the roller to keep it pressed against the groove. In one embodiment, a flexible strip is positioned above each roller to bias the roller in a downward direction against the lower inside of the groove.

[0022] In one embodiment, the vehicle is an electric vehicle powered by a battery pack stored underneath the truck, hi another embodiment, the truck may be a hybrid gasoline truck or a fuel cell truck, or any combination thereof.

[0023] FIG. 1A shows a vehicle 100 having a cab 103 and a cargo bed 104. The cab 103 includes a sloped roof 105 that slopes towards the cargo bed 104 in this embodiment. In one embodiment, the sloped roof 105 covers a portion of the passenger compartment of the cab 103. A tonneau cover 110 according to the present disclosure covers the cargo bed 104. As shown, the tonneau cover 110 may be deployed to completely cover the truck bed and extend all the way from the rear 107 of the cab 103 to the tailgate 108 of the vehicle 100. As shown, the cover 110 provides a relatively smooth, flat surface that extends at the same angle from the sloped roof 105 to the tailgate 108. The transition from the sloped roof 105 to the cover 110 is flush so that the extended cover is at approximately the same angle as the sloped roof 105.

[0024] 1B shows the vehicle 100 with the tonneau cover 110 in a retracted position. In one embodiment, at the rear 107 of the cab 103, there is an articulating panel 112 that connects the cab 103 to the cargo bed 104. The articulating panel 112 is configured as a small rearward facing panel that provides an upper boundary from which the cover 110 deploys. In the extended position, the cover 110 overlaps the top of the cover 110 such that rain or moisture hits the articulating panel 112, travels over the cover 110, and then drains out the rear of the vehicle 100.

[0025] Beneath the connecting panel 112 is an upwardly facing opening 130 that allows the tonneau cover 110 to be rolled up and down from under the vehicle 100. When the tonneau cover 110 moves from the retracted position to the extended position, it moves through the upwardly facing opening 130 to under the connecting panel 112. The opening 130 is formed in part from the rear wall 120 of the cab 103. The rear wall 120 is used to prevent the tonneau cover 110 in the retracted position from colliding with and damaging objects placed in the cargo bed 104. For example, while the vehicle 100 is moving, objects stored in the cargo bed 104 may move within the cargo bed 104. The rear wall 120 prevents these objects from colliding with and potentially damaging the retracted tonneau cover.

[0026] As shown in FIG. 1B, in one embodiment, the tonneau cover 110 can be fully retracted into the opening 130 such that the tonneau cover 110 is fully stored behind or below the rear wall 120. In one embodiment, the tonneau cover 110 is stored in or below the opening 130 or in a structure disposed between the cab and the cargo bed of the vehicle. For example, the tonneau cover 110 may be retracted with the front of the tonneau cover 110 stored below the rear cab window 140 of the vehicle 100 so as not to obstruct the driver's rearward view out of the cab 103. This capability allows the driver to see out through the rear cab window 140 when the tonneau cover 110 is in a retracted position (e.g., rolled and stored as described above). This allows the driver to see into the cargo bed 104 from the cab 103. Also, a person loading cargo into the cargo bed 104 can see into the cab through the rear cab window 140. When in the reverse or stowed position, the tonneau cover 110 is rolled up and stowed beneath the juncture of the cab 103 and the cargo bed 104, as will be described in more detail below.

[0027] When the tonneau cover 110 is deployed, each slat within the cover rides on rollers across the cargo bed 104, upward from the opening 130, within a set of side channels or rails 150A, 150B.

[0028] 1A and 1B, the grooves 150A / 150B extend along the upper edge of the truck bed, which slopes at a downward angle, higher near the cab 103 and lower near the tailgate 108. Thus, the tonneau cover 110 deployed over the bed 104 slopes downward toward the tailgate 108 at an angle that matches the angle of the sloped roof 105. This slope allows water, snow, mud, ice, and other outdoor elements to run down the tonneau cover 110 and out of the vehicle 100, thereby minimizing the weight on the tonneau cover 110 and vehicle 100 caused by such outdoor elements and improving the performance of the vehicle 100. In one embodiment, the transition from the rear of the tonneau cover 110 to the top of the tailgate 108 is a smooth transition that allows water, snow, and the like to run down the cover and over the top of the tailgate 108.

[0029] 2, as shown, the tonneau cover 110 in the retracted or stowed position forms a spiral at a position behind the passenger compartment of the cab 103. The tonneau cover 110 slides downward at the end of the bed 104 below the level of the rear cab window 140 so that the driver can see out of the rear cab window 140 when the tonneau cover 110 is in the retracted or stowed position. In one embodiment, a central motor (shown in FIG. 3) rotates to unroll the tonneau cover 110 so that the tonneau cover 110 is rolled down across the top of the bed 104 and into grooves 150A / 150B (on each side wall of the bed 104).

[0030] FIG. 2 further illustrates the movement of the tonneau cover 110 as it is unrolled from a position beneath the cab 103 and extended from a front portion of the cargo bed 104 to a rear portion of the cargo bed 104.

[0031] It should be understood that the motor and tonneau cover configuration shown in Figure 2 is not the only configuration that will allow the cover to slide over the bed. For example, a motor connected to a roll-up tonneau cover can be attached to a distal end of the tonneau cover 110 and connected to a pulley system that pulls on a cable that helps pull the tonneau cover 110 out of the swirl and onto the bed 104. Thus, movement of the motor pulls on the cable, which in turn pulls the cover into either a retracted or extended position depending on the direction of the motor movement.

[0032] FIG. 3 shows a side cross-sectional view of one design of a rolled-up tonneau cover 110, which is made from a series of slats or movable parts 310 flexibly connected to each other so that the tonneau cover 110 can be rolled around a central axis on which a motor 320 is located.

[0033] As mentioned above, each side edge of the tonneau cover 110 slides inside the grooves 150A / 150B and is actuated by the motor 320 which rotates to move the tonneau cover 110 out of the opening 130 and onto the cargo bed 104.

[0034] In one embodiment, tonneau cover 110 may be made from a series of movable parts 310, each with a set of bearings (not shown) attached to either side and configured to fit within grooves 150A / 150B. Each movable part 310 is connected to its adjacent movable part 310 by a flexible linkage 315 that allows the cover to be rolled up and extended along its grooves.

[0035] In one embodiment, motor 320, which controls the position of tonneau cover 110, may be configured to wind or unwind the tonneau cover 110 as it moves across the top of the cargo bed 104 within grooves 150A / 150B in the top edge of the cargo bed 104. In one embodiment, when motor 320 rotates in one direction, tonneau cover 110 is pushed out of opening 130 and unrolled as it moves out of the cab 103 and towards the tailgate 108 of the cargo bed 104. When motor 320 rotates in the opposite direction, tonneau cover 110 is pulled back to its stowed position below the cab 103.

[0036] In one embodiment, the motor 320 directly controls the movement of the tonneau cover 110, and may increase the speed of movement compared to when there is some intervening part between the motor 320 and the tonneau cover 110 to control the movement of the tonneau cover 110. In one embodiment, a drive assembly is packaged coaxially within the center of the volute of the tonneau cover 110 in the retracted position shown in FIG. 3. In one embodiment, the motor 320 is connected to the tonneau cover 110 through a central rotating drum, with a plunge rod and linear ball bearing assembly mounted at right angles to the drum. The plunge rod is attached to a hinged brace that drives the connected movable part 310. In one embodiment, the motor 320 may rotate clockwise and counterclockwise at a desired speed. In an alternative embodiment, a pair of motors with profiled wheels may rotate clockwise or counterclockwise at a desired speed. In one embodiment, the contoured wheels include a toothed mechanism that can engage with roller shafts attached to the movable portion 310 and push the tonneau cover 110 out of the opening 130 to deploy it, or retract them into the opening 130 to retract the tonneau cover 110.

[0037] It should be appreciated that many different mechanisms can be used to open and close the tonneau cover 110 from a position below the cab 103 to an extended position covering the cargo bed 104. Because the tonneau cover 110 is integral to the vehicle 100 and not attached after manufacture, the tonneau cover 110 can provide a strong weatherproof seal whether in the open or closed position.

[0038] To open or close the tonneau cover 110, a user can press an activation button inside or outside the cab 103. In one embodiment, the activation button is located on top of one of the grooves 150A / 150B located adjacent the loading platform 104. Alternatively, the user can insert a key into a key hole located on the exterior of the vehicle 100. In an alternative embodiment, the vehicle 100 can have wireless access and the tonneau cover 110 can be opened or closed using a wireless device such as a cell phone that can be used to access an application program configured to control the movement of the tonneau cover 110. In another embodiment, the cab or loading platform 104 can include a display screen having a user interface with programmed buttons that can be activated by touch detection to control the movement of the tonneau cover 110 from an open position to a closed position. In one embodiment, the drive system associated with the movement of the tonneau cover 110 uses multiple systems for parallel safety measures. In one embodiment, one such system is driven primarily by two microswitches that can identify a specific open position and a specific closed position. In one embodiment, a high-resolution encoder constantly monitors the position of the tonneau cover 110. In one embodiment, the motor 320 may provide a force feedback feature that allows for disabling power to the motor 320 when a predetermined force, and therefore current, is applied to the motor. In an alternative embodiment, a multi-conductor pinch sensor is attached to the edge of the tonneau cover 110 that can suspend the automatic movement of the tonneau cover 110 at any point during its normal movement if the sensor is activated. In another embodiment, the drive system associated with the movement of the tonneau cover 110 is based on either capacitive or tactile sensing technology that is used to detect the presence of any obstacles during the movement of the tonneau cover 110. In one embodiment, such technology of the drive system may allow the tonneau cover 110 to have the ability to automatically reverse throughout its range of motion when an obstacle is detected. Such a capability can protect the cargo and the tonneau cover 110 (and its system components) from damage.In one embodiment, a pinch sensor may be integrated into the carrier that is attached to the movable portion 310 closest to the tailgate 108 .

[0039] In one embodiment, tonneau cover 110 includes solar cells electrically connected to a photovoltaic charging system and a battery. In one embodiment, the battery is a vehicle battery that powers vehicle 100, which in one embodiment may be an electric truck. When tonneau cover 110 is deployed over cargo bed 104 and the solar cells that make up the slats face the sun, a battery in the electric vehicle can be charged by the solar cells.

[0040] FIG. 4 illustrates one design of the movable parts 310 and linkage 315 of the tonneau cover 110, in which the movable parts are flexibly connected to each other. A first half-moon shaped end 410 of each movable part 310 can be connected to a second rounded end 420 to form the linkage 315. As shown, the first end 410 and the second end 420 of two adjacent movable parts 310 can be flexibly connected in such a manner that the first end 410 and the second end 420 can rotate or pivot relative to each other to allow each movable part 310 to flexibly connect to each adjacent part. As the movable parts 310 move relative to each other, they close the gap 450 formed between the two adjacent movable parts 310. When the tonneau cover 110 is in a rolled up configuration, the gap 450 is wider, and as the tonneau cover 110 is deployed flat across the vehicle bed, the gap 450 becomes narrower. When the tonneau cover 110 is fully extended over the cargo bed 104, the outer surfaces 425 of the two adjacent movable portions 310 form a flat position. This may be useful in allowing any outdoor elements to run down the tonneau cover 110 and out of the vehicle 100, based on the sloping shape of the top of the cargo bed 104, as discussed above. In one embodiment, the vehicle 100 may include a separate gutter that is used to further direct any water or outdoor elements that need to drain out of the cargo bed 104 and out of the vehicle 100.

[0041] In one embodiment, first end 410 and second end 420 are separated by a strip 430 located between an inner surface of first end 410 and an outer surface of second end 420. In one variation, strip 430 is made of polytetrafluoroethylene (PTFE) (e.g., Teflon) and has dimensions that help reduce noise levels associated with first end 410 and second end 420 rubbing against each other when tonneau cover 110 or vehicle 100 is in motion.

[0042] In one embodiment, each of the movable portions 310 that make up the tonneau cover 110 includes a weatherstrip 440 disposed within a groove 445 that extends the length of each movable portion 310. The weatherstrip 440 includes an attachment portion 447 and a flexible contact portion 448. The attachment portion 447 engages the weatherstrip 440 and slides the weatherstrip 440 into the groove 445 of the movable portion 310. The flexible contact portion 448 protrudes into a gap 450 formed between each movable portion 310 to provide a water-tight and weather-tight seal between each movable portion when the tonneau cover 110 is in the extended position. The weatherstrip 440 can be locked to an adjacent movable portion 310 such that the tonneau cover 110 moved to the closed position has a water-impermeable surface. The weatherstrip 440 may be made of a durable, flexible material, such as rubber, to provide a wind-tight seal between adjacent movable portions of the tonneau cover 110. When the tonneau cover 110 is placed in the extended position, the weatherstrip 440 is placed in a locked or closed position to close the gap 450 formed between two adjacent movable parts 310 and apply a sealing pressure, thereby providing a water impermeable surface.

[0043] 5A and 5B show views of a side end 500 of the movable portion 310 of the tonneau cover 110. As shown, the movable portion 310 of the tonneau cover 110 includes an end cover 503 attached to the end of each movable portion 310. The end cover fits to the movable portion 310 on one side and provides a mount for two spacers 530A, 530B. In one embodiment, there are four rollers connected to each movable portion 310, each roller rotatably attached to each slat via a ball bearing. In one embodiment, the ball bearings have a static load rating of 300 pounds. Each side of the slat has a pair of ball bearings and rollers. In one embodiment, calculations and basic FEA (finite element analysis) have confirmed that the movable portion 310 can handle loads from misuse, such as from a 95th percentile male standing on the tonneau cover 110 or from a certain amount of snow piled up on the tonneau cover 110, without significant deflection or component failure beyond a certain threshold.

[0044] Adjacent to each spacer 530A, 530B is a roller 520A, 520B that rolls on ball bearings and allows the movable part to slidably engage a groove that runs along the side of the vehicle. Adjacent to each of the rollers 520A, 520B is a flexible strip 510 that is attached and disposed on the outside of the rollers 520A, 520B. In some embodiments, the rollers 520A, 520B are wheels or bearing / roller assemblies. The rollers 520A, 520B are used to move the movable part 310 (and thus the tonneau cover 110) within and along the grooves 150A / 150B of the cargo bed 104. When rollers 520A, 520B move during operation of tonneau cover 110 or remain in place within groove 150A / 150B during operation of vehicle 100, flexible strip 510 abuts against the upper or lower portion within groove 150A / 150B to bias rollers 520A, 520B against moving up or down, as can be more easily seen with reference to FIG. 5B. As shown, flexible strip 510 is sized and positioned to press against inner upper portion 550 of groove 150A. Such a design may be useful to reduce noise levels associated with movement of rollers 520A, 520B within groove 150A / 150B, or stress levels in rollers 520A, 520B and movable portion 310 or other connecting portions of groove 150A / 150B.

[0045] The flexible strip 510 is configured to provide enough bias to the rollers 520A, 520B so that the rollers remain connected to the groove 150A when the vehicle is moving and cannot bounce up and down within the groove. However, the flexible strip 510 does not provide so much bias that the rollers 520A, 520B cannot roll within the groove 150. In one embodiment, the flexible material is made from a plastic, metal, or other material that is flexible but can slide inside the groove to provide the correct amount of bias to the rollers 520A, 520B.

[0046] The groove 150A may be configured in any shape that will retain the rollers and allow for extension and retraction of the cover 110. For example, the groove may be "U" shaped as shown in FIG. 5B. The groove may also be more "V" shaped, or conical. Additionally, the lower portion of the groove may have features that allow water to drain from the interior of the truck bed. For example, in one embodiment, the lower portion of the groove may have a channel configured to keep water from entering the bed, and instead run down the side of the truck and out near the tailgate. In other embodiments, the groove may have an orifice configured to allow water to drain out onto the roadway outside the groove, rather than into the bed.

Additionally, the order of the operations may be rearranged. A process may correspond to a method, a function, a procedure, a subroutine, a subprogram, etc. When a process corresponds to a function, its termination may correspond to a return of the function to the calling function or to the main function.

[0051] Features or functions described with respect to certain exemplary embodiments can be combined and partially combined in various other exemplary embodiments and / or with various other exemplary embodiments. Also, different aspects and / or elements of the exemplary embodiments can be combined and partially combined in a similar manner as disclosed herein. Furthermore, some exemplary embodiments, individually and / or collectively, may be components of larger systems, and other procedures may take precedence over their application and / or modify their application in other ways. Furthermore, some steps may be required before, after, and / or simultaneously with the exemplary embodiments as disclosed herein. It should be noted that at least any and / or all methods and / or processes disclosed herein can be at least partially performed in any manner via at least one entity or actor.

[0052] Terms used herein may mean direct or indirect, complete or partial, temporary or permanent, operative or inoperative. For example, when an element is referred to as being "on" or "connected" to or "coupled" to another element, the element may be directly "on" or "directly connected" to or "directly coupled" to the other element, and / or there may be intervening elements, including indirect and / or direct variations. In contrast, when an element is referred to as being "directly connected" to or "directly coupled" to another element, there are no intervening elements present.

[0053] In this specification, terms such as first, second, etc. may be used to describe various elements, components, regions, layers, and / or portions, but these elements, components, regions, layers, and / or portions should not necessarily be limited by such terms. These terms are used to distinguish one element, component, region, layer, or portion from another element, component, region, layer, or portion. Thus, a first element, component, region, layer, or portion described below can be referred to as a second element, component, region, layer, or portion without departing from the teachings of the present disclosure.

[0054] The terms used herein are for the purpose of describing certain exemplary embodiments and do not necessarily limit the disclosure. As used herein, the singular forms "a," "an," and "said" are intended to include the plural unless the context clearly indicates otherwise. Also, as used herein, the terms "a" and / or "an" shall mean "one or more," although the phrase "one or more" is also used herein. The terms "comprises," "includes," and / or "comprises," as used herein, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not exclude the presence and / or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof. Furthermore, when the disclosure states that something is "based on" something else, it indicates that such a statement can also be based on one or more other things. In other words, unless otherwise specified, "based on" as used herein means "based at least in part" or "based at least in part" inclusively.

[0055] As used herein, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or." That is, unless otherwise specified or clear from the context, "X uses A or B" is intended to mean any of the natural inclusive permutations. That is, if X uses A, if X uses B, or if X uses both A and B, then "X uses A or B" is satisfied in any of the foregoing cases.

[0056] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure belongs. Terms as defined in commonly used dictionaries should be interpreted to have a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized and / or overly formal sense unless expressly so defined herein.

[0057] This detailed description has been presented for various purposes of illustration and explanation, but is not intended to be exhaustive and / or limiting of the present disclosure in its various disclosed forms. Many modifications and variations of techniques and structures will be apparent to those skilled in the art without departing from the scope and spirit of the present disclosure as set forth in the various claims that follow. Accordingly, such modifications and variations are considered to be part of the present disclosure. The scope of the present disclosure is defined by the various claims, including known equivalents and unforeseen equivalents at the time of filing of the present disclosure.
