Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claims. Specific dimensions and other physical characteristics relating to the embodiments disclosed herein are therefore not to be considered as limiting, unless the claims expressly state otherwise.

[0063] A modular electric truck system 100 is referenced in FIGS. 1-18C. The modular electric truck system 100, hereafter system 100 provides an electric truck 120 that is powered by at least one photovoltaic solar panel 800a-d, and has a reconfigurable body chassis 102 that can adapt to receive interchangeable modular body components 500a-c. At least one trailer 1000a-g operatively attaches to the electric truck for tethered connectivity, or remote control tracking and following; or autonomous tracking and following to the electric truck chassis 120.

[0064] As referenced in FIG. 1, the electric truck 120 includes a chassis 102, such as those used with a truck, van, or semi-truck. The chassis 102 forms the base frame of the truck. The exterior and interior layout, structure, architecture is modifiable. The chassis 102 is created to be scalable in order to easily modify the structure to create different shapes, sizes, and types of vehicles as well as integrate various powertrain systems, charging methods, and technology, referred to as NSC=Neuron Scalable Chassis or SC=Scalable Chassis or NC=Neuron Chassis or SP=Scalable Platform.

[0065] In one embodiment, the chassis 102 is defined by rounded rectangular and or square shapes and or structures represented by 4 sides connected by 4 rounded corners. This shape is unique because the electric truck is referred to as (Squargle or SQR) used as architecture, structure, or function in automotive applications. The Squargle is a structure that can be used but not limited to a lighting architecture (SLA=Squargle Light Architecture) throughout the vehicle. The rounded rectangle is a shape that represents electric truck.

[0066] The electric truck is unique because the identity of neuron is a cell symbolized by the Squargle an enclosed entity created with four structures (flat sides) connected by 4 joints (rounded corners). Therefore the Squargle in essence is the representation of the electric truck, which in essence is an automotive cell that conducts change in the transportation industry.

[0067] Further, the system 100 integrates various attachments, interchanging architectures, and structural modularity to expand functionality while driving, stationary utility, technology, performance, passenger load capacity, storage capacity, and overall vehicle capability. In one embodiment, the pickup truck converts to a sports utility vehicle (SUV) by removing, or covering the truck open bed with a shell (See FIGS. 6 and 7, for example). The SUV configuration provides additional coverage for the interior cabin, and also includes additional seats for added passenger capacity. The SUV configuration is similar to the van configuration described below.

[0068] For example, the electric truck 120 comprises a scalable chassis 102 that can be equipped with multiple interchangeable body components 500a-c that easily attach and detach to a rear portion 106 of the truck chassis 102 to change the appearance and functionality of the electric truck 120. In one embodiment, the chassis 102 comprises a front portion 104 oriented towards the forward motion of the electric truck 120. The front portion 104 is defined by an interior cabin 200.

[0069] The chassis 102 also comprises a rear portion 106 juxtaposition to the front portion 104. The rear portion 106 is defined by an open truck bed 108, and a roof 110. The enclosed rear truck bed space provides additional seating for up to 6 passengers. The roof 110 of this enclosed shape may house a photovoltaic solar panel 800b for charging vehicle battery 114 simultaneous while driving or stationary in parked position. The rear open bed is capable to haul an additional trailer or any storage structure with wheels. Such a multi-task rear open bed changes the purpose and function of the electric truck 120, allowing for multiple task, such as: sanitation, postal delivery, delivery of service and goods, cargo transport, mobile home, and food service.

[0070] Looking now at FIG. 2, the front portion 104 of the chassis 102 is defined by an interior cabin 200 in which the driver and passenger sits on at least one seat 206a-c. The driver sits in a center driving position in a front seat 206a of the interior cabin 200. The center driving position is characterized by the driver sitting in a central position of the interior cabin, for increased visibility and non-biased awareness of truck position. The passengers sit in a left side seat 206b and a right side seat 206c behind the driver.

[0071] The interior cabin 200 also include a steering member 202 operatively connected to the front wheels 116a, 116b for steering thereof. Multiple rear wheels 118a, 118b sit behind the front wheels 116-b. The interior cabin 200 also includes an illumination portion 204 that lights up the dashboard. In one embodiment, the illumination portion 204 comprises a horizontal lighting architecture. The horizontal beam of light may be referred to as The Horizon or Neuron Horizon which is the light source that harmonizes the lower and upper body while creating a strong foundation of stability. In other embodiments, a radio and a speaker system 100 212a, 212b, 212c, 212d may also be available in the interior cabin 200 for entertainment.

[0072] As shown in FIG. 3, the interior cabin 200 also includes at least one communication interface 210a, 210b, and a computer 208 having a software program in the interior cabin allow the driver and passenger to have further control of the components and communications of the system 100. The communication interface may be a touch screen that allows the driver to control aspects of the electric truck, such as remote control, braking capacity, entertainment, and other driving related functions.

[0073] Additionally, the electric truck 200 is unique with a cab forward design, further characterized by a continuous cabin profile defined by a short hood length, raked front windshield. This unique configuration creates a harmonized hood to cabin profile. Furthermore, the driver position is near or above front wheel axle allowing for increased rear passenger and rear storage space.

[0074] In one possible embodiment of the system 100, the interior cabin 200 is defined by a driving space that can be used as a mobile habitat such as the Truck Series, Pickup Truck, Light to Medium Duty Truck, Semi Truck with sleeper cabin and Mobile Lounges. The interior cabin may include a sleeper cabin referred to as Mobilized Dwelling or Mobile Loft or Vehicle Loft or Dynamic Sleeper. The sleeping cabin is unique because the space provided is customizable similar to a hotel room or studio apartment described as CVI=Customizable Vehicle Interior, where the driver and passengers are able to openly customize the vehicle interior space.

[0075] Thus, as shown in the right side rear view of FIG. 4, the driver and passenger are provided with a quiet and comfortable living space with tools to accommodate long hours of driving. Due to the fact that the interior cabin 200 is designed to be like a home, the space is specifically able to integrate any additional technology that the user desires which includes but not limited to mobile phones, tablet, computer 208, internet, entertainment system. Such an interior cabin contributes positively to humanity through automotive innovation by mobilizing the flexibility and convenience that is not provided in present combustion or electric vehicles.

[0076] Turning now to FIGS. 5-7, the system 100 provides at least one modular body component 500a-d detachably attachable to the open truck bed 108 and/or the roof 110 of the chassis 102. The modular body component may attach to the rear portion 106 of the chassis 102 through bolts, screws, slidable rails, welding, a snap-fit relationship, or combinations thereof. In one embodiment shown in FIG. 5, the modular body component comprises a front guard 500a and a van shell 500b. The van shell 500b converts the truck into a van. In one example, a pickup truck converts to a van through a modular rear truck bed that converts the bed into an extension of enclosed interior space.

[0077] In other embodiments shown in FIG. 6, the modular body component may include a truck bed shell 500c and multiple interchangeable roofs 500b having different sizes. The use of truck bed shell 500c and interchangeable roofs creates a large pickup truck configuration that can be used to store items in the rear portion 106 safe from the elements. The roofs 500b may have different heights to accommodate the various load requirements for the open truck bed 108. FIG. 7 illustrates an elongated truck bed shell 500d that is up to 50% longer than truck bed shell 500c. The elongated truck bed shell 500d detachably mates to the sides of the open truck bed 108. Though in some embodiments, the open truck bed may be elongated to accommodate the elongated truck bed shell 500d.

[0078] In another exemplary mode of the truck, the pickup truck converts to a semi-trailer truck. The semi-trailer conversion allows the pickup truck to remove the pickup bed, and replace with a lower rear mounting bed 1406. In this manner, the pickup truck can tow various types and sizes of trailers. For example, FIGS. 14A-14C illustrate side views of the modular electric truck system for a base model 1400, without trailers tracking the truck. FIG. 14A shows a base vehicle 1400 with a truck bed 1402 at the rear portion. In a longer version of the truck, FIG. 14B shows a base vehicle 1404 with the truck bed 1402 removed to reveal a lower rear mounting bed 1406. FIG. 14C shows the base vehicle 1406 with the rear cabin, roof, and mounting bed interchanged, so that the lower mounting bed 1410 is extendable without a wheelbase extension. Multiple additional rear wheels are added to the lower mounting bed 1410 in this configuration.

[0079] In some embodiments, the system 100 provides a pair of steerable front wheels 116a-b supporting the front portion 104 of the chassis 102. Additionally, at least two laterally spaced rear wheels 118a-b supporting the rear portion 106 of the chassis 102. In some embodiments, at least one additional wheel 700 is operational to the rear portion 106 of the chassis 102, adjacent to the rear wheels (FIG. 7). The additional wheels 700 allow for an all-wheel drive conversion of the electric truck. As illustrated, two sets of spaced-apart additional wheels 700 sit behind the rear wheels 118a-b.

[0080] Turning back to FIG. 1, the system 100 provides at least one hub motor 112a, 112b that is operational with any of the aforementioned wheels 116a-b, 118a-b, 700. The hub motor 112a, 112b may be inside the wheels. Each hub motor 112a, 112b operational to drive a respective wheel. In one embodiment, the hub motor 112a, 112bs are encompassed and operational inside the front wheels. In another embodiment, the hub motor 112a, 112b is encompassed and operational the front and rear wheels 116a-b, 118a-b, creating an all-wheel drive truck.

[0081] In some embodiments, the system 100 further comprises a regenerative electric braking circuit 214 for decelerating the electric truck 120. The regenerative electric braking circuit 214 is operatively connected to the hub motor 112a, 112b, whereby the electric braking circuit causes electric braking of the wheels. In this configuration, the hub motor 112a, 112b generates a back electromotive force that feeds the battery as a result of the braking. However in other embodiments, different braking means known in the art of automotive may also be used.

[0082] Looking now at FIG. 8, the system 100 provides at least one photovoltaic solar panel 800a-d. The photovoltaic solar panel is operatively connected to the battery 114 for recharging the battery. The solar panel charges the battery that operatively connects to the at least one hub motor 112a, 112b in the wheels 116a-b, 118a-b, 700. Those skilled in the art will recognize that photovoltaic solar panels absorb sunlight as a source of energy to generate electricity.

[0083] FIG. 8 references the photovoltaic solar panel 800a, 800b disposed on the open truck bed 108 and/or the roof 110 of the chassis, respectively. FIG. 9 shows a photovoltaic solar panel 800c lying along the longitudinal of the truck bed shell 500c. And FIG. 10 shows the photovoltaic solar panel 800d operational in the trailer 1000a. However it is significant to note that any combination of positions for photovoltaic solar panel 800a-d may be used on the electric truck 120 and modular body components 500a-c.

[0084] As discussed above, the electric truck 120 is electrical; and thereby a battery 114 is utilized for powering thereof. The battery 114 operatively connects to the hub motor 112a-b. Those skilled in the art will recognize that electric-vehicle batteries differ from starting, lighting, and ignition (SLI) batteries because they are designed to give power over sustained periods of time. Deep-cycle batteries are used instead of SLI batteries for the electric truck system. The battery may include, without limitation, a lead-acid battery, a nickel metal hydride, a lithium-ion battery.

[0085] Turning now to FIG. 11, the system 100 may include at least one trailer 1000a-g that is operatively attached to the chassis 102. The trailer 1000a-g can follow the chassis 102 in a tethered, wireless, or autonomous configuration. In some embodiments, the trailer may be used to carry people, animals, and supplies. The trailer 1000a-g is adapted to receive and orient at least one of the solar panels for generating electricity for the battery 114.

[0086] In one embodiment, a tethered trailer 1000b is tethered to the rear portion of the chassis through a tether 1100, a chain, cable, or other towing mechanisms known in the art. In the tethered configuration, the trailer 1000b may be non-motorized, simply being pulled by the chassis of the electric truck. In some embodiments, multiple interchangeable trailer roofs 1004 may be used to change the dimensions and shape of the trailer, similar to the electric truck chassis 102. The interchangeable trailer roofs 1004 can have different heights and aerodynamic shapes.

[0087] In another embodiment shown in FIG. 12, a wireless trailer 1000c is wirelessly attached to the chassis 102, and controlled with a remote control system 1200, or a remote multi-haul system. The trailer 1000c may be motorized in this wireless configuration. The remote control system 1200 is disposed in the interior cabin 200 where the driver or passenger can access it easily. However in other embodiments, the remote control system 1200 is controlled from a remote region, away from the electric truck 120.

[0088] The remote control system 1200 is configured to enable the driver, passenger, or remote user to remotely control the wireless trailer 1000c. In some embodiment, the remote control system 1200 comprises a transceiver 1202 in operational connectivity with the software program (FIG. 12). The transceiver 1202 is operable to send and receive radio frequency signals, including messages, location data, information requests, and control codes. However in other embodiments, the interior cabin 200 may have a transmitter and the trailer may have a receiver, as known in the art of remote control.

[0089] In this manner, the remote control system 1200 is operable to wirelessly control operation of the steering member 202, hub motor 112a, 112b, and brake circuit 214, so as to power and steer the trailer 1000c, such that the wireless trailer 1000c can track and follow the chassis per commands transmitted by the driver, passenger, or remote user. In yet another embodiment, multiple autonomous trailers 1000d, 1000e, 1000f, 1000g follow and track the electric truck (FIG. 13). The autonomous trailers 1000d-g may operate independently of each other, or operate in tandem.

[0090] As described above, the pickup truck converts to a semi-trailer truck by removing the pickup bed, and replacing with a lower rear mounting bed 1406. In this manner, the pickup truck can tow various types and sizes of trailers. In one possible use of the semi-trailer truck conversion, FIGS. 15A-15C illustrate side view of the modular electric truck system for a semi-truck configuration of the base model. Here, FIG. 15A shows a truck 1500 with a removable truck bed 1502. Further, FIG. 15B shows the truck 1504 having a truck bed tow extension 1506. And further, FIG. 15C shows the truck 1504 having a truck bed tow extension 1506 with a detachable rear attached tow extension bed 1508 that is motorized and operable autonomously, so that the lower mounting bed is extendable without a wheelbase extension.

[0091] In another exemplary trailer provided in the present invention, FIG. 16A shows a semi-truck conversion truck 1600 with interchangeable and attachable open container rear compartment 1602.

[0094] In some embodiments, the software program is operational to control the autonomous trailers 1000d-g, the remote control system 1200, the illumination portion 204, the battery 114, and the hub motor 112a-b. In other embodiments, the software program enables autonomous control of the autonomous trailers 1000c-g by communicating with a processor in the trailer. The software program may utilize tracking components and software known in the art, i.e., GPS, towers, etc. The system is configurable to expand/upgrade software and hardware to integrate various technologies to support performance, safety, and convenience such as autonomous driving and have the ability to provide various functions fit for the user and/or infrastructure.

[0095] As discussed above, the system is 100% electrical, and thus, must be charged regularly. Thus, the system 100 provides a unique charging trailer 1000a that provides convenient electrical charging cable 1002 for recharging the battery 114 of the electric truck 120. The charging trailer 1000a may also be used to charge other electric vehicles that require charging. The charging trailer 1000a may operate separately from the electric truck, or may attach to the rear portion of the electric truck, charging the battery 114 while simultaneously being towed.

[0096] The trailer 1000b may have rechargeable batteries 1102 that are charged from the at least one photovoltaic solar panel 800d, 800e on the charging trailer 1000a, or one of the solar panels on the roof 110 or rear open bed 108 of the truck chassis 102. A hub motor 1100a, 1100b on each wheel 1104a, 1104b connects with the rechargeable batteries 1102 in the trailer 1000b. In yet another embodiments of the trailer 1000a, the chassis itself converts into a converted trailer. For example, a main frame of the electric truck 120 can be used to convert into the trailer. Thus, the system 100 utilizes myriad combination of trailer shapes and functions.

[0097] In some embodiments, the trailer 1000a-g may be motorized or non-motorized. The trailer 1000a-g is in a shape of a rectangular structure that can be upgraded further with autonomous technology, converting into an autonomous rectangular vehicle. The trailer 1000a-g can be used as a living space such as a home or for various outdoor activities such as camping and provides an enclosed shelter for sleep during travel. The space can be customized for various purposes such as a food truck, delivery vehicle, locker for storage/goods, merchandise pop-up store.

[0098] In conclusion, the modular electric truck system 100 provides an electric truck 120 that has a scalable chassis 102 that can be equipped with interchangeable modular body components 500a-c that detachably attach to the truck chassis to change the appearance and functionality of the electric truck. An interior cabin 200 comprises furniture, lighting elements, computer devices, and entertainment systems. The driver sits in a center driving position where visibility and positional awareness is enhanced. The electric truck is 100% electrical; and thereby provides convenient electrical charging means for the truck through a charging trailer that attaches to the truck, and/or at least one solar panel on the roof, bed, or trailer of the truck. The solar panel charges a battery that operatively connects to a hub motor in the wheels. A remote control system remotely controls at least one trailer. The trailer may be tethered, wireless, or autonomous to wirelessly track and follow the electric truck 120.
