Description:TECHNICAL FIELD
The present disclosure relates to battery systems for two-wheeled electric vehicles. Moreover, the present disclosure relates to interchangeable and transportable battery assemblies designed for enhancing convenience and functionality in a two-wheeled electric vehicle operations.
BACKGROUND
In recent years, electric vehicles, particularly two-wheeled electric vehicles, have become increasingly popular due to their environmental benefits and reduced operating costs. Particularly, the two-wheeled electric vehicles depend on efficient and reliable battery systems to function effectively. One of the challenges faced in the electric vehicle industry is the ease of access, charging, and replacement of battery packs in such vehicles. Typically, battery packs in two-wheeled electric vehicles are rigidly mounted within a chassis, making their removal and replacement cumbersome, particularly in outdoor or emergency conditions.
The existing technology for two-wheeled electric vehicle battery systems often lacks the flexibility required for quick and convenient battery access or replacement. Current battery systems either require extensive manual labour or the use of external tools to dismount the battery. Moreover, the current battery systems do not offer portability features that would allow users to remove and transport the battery pack easily. Additionally, safety concerns arise due to the absence of locking mechanisms that prevent the battery system access. At the same time, the two-wheeled electric vehicle is in motion, or there is a lack of weather resistance around access points for battery replacement.
Therefore, in light of the foregoing discussion, there exists a need to overcome the aforementioned drawbacks associated with conventional battery systems.

SUMMARY
The present disclosure provides a battery system for a two-wheeled electric vehicle. The present disclosure provides a solution to the existing problem of how to facilitate easy access, replacement, and transportation of battery packs in two-wheeled electric vehicles without compromising the structural integrity or safety of the two-wheeled electric vehicle. An objective of the present disclosure is to provide a solution that overcomes at least partially the problems encountered in the prior art and provides an improved system for battery access and management.
One or more objectives of the present disclosure are achieved by the solutions provided in the enclosed independent claims. Advantageous implementations of the present disclosure are further defined in the dependent claims.
In one aspect, the present disclosure provides a battery system for a two-wheeled electric vehicle. The battery system includes a battery pack housed within a carrier. Further, the battery system includes the carrier integrated into a chassis of the two-wheeled electric vehicle with a dedicated access point. The battery system further includes a hinge connecting the carrier to the chassis. The hinge allows the carrier to pivot relative to the chassis and a lock for securing the carrier within the chassis.

The holder 208 interacts with other components like side support and cushions ( the upper cushion 206 and the lower cushion 218) to prevent unwanted movement or vibrations that could affect the performance or safety of the battery system 102.
FIG. 2B is a diagram illustrating the battery system in a stored position, in accordance with an embodiment of the present disclosure. FIG. 2B is described in conjunction with elements from FIGs 1 and 2A. With reference to FIG. 2B, there is shown the battery system 102 in an accessible position. The accessible position refers to the configuration of the battery system 102 when the carrier 104, containing the battery pack 108, is tilted outward from the chassis 118 of the two-wheeled electric vehicle 100, making the battery easily accessible for removal or insertion.
The tilt stopper prevents further movement beyond the intended angle, ensuring stability. In the accessible position, the battery pack 108 is fully exposed for easy handling, with a handle available for manoeuvring the battery system 102. During this process, protective cushions (i.e., the upper cushion 206 and the lower cushion 218) remain in place to safeguard the battery system 102 from impacts or damage
Referring to FIGs.2A and 2B, the lock hinge 214 refers to a secondary hinge mechanism that connects the carrier 104 to the chassis 118 in the battery system 102 and allows controlled tilting of the carrier 104 into the accessible position and includes a locking feature to secure the carrier at the desired angle. The lock hinge 214 supports the weight of the battery pack 108 and ensures stability during the tilting process while preventing accidental disengagement when the two-wheeled electric vehicle 100 is in operation. It provides both pivotal motion and locking security. The battery pack 108 is securely housed within the carrier 104. The carrier 104 is vertically aligned within the chassis 118 of the two-wheeled electric vehicle 100, likely fitting into a dedicated compartment. The lock 106 is engaged, securing the carrier 104 to the vehicle frame. The pivot hinge 110 and frame hinge 210 are in their closed positions. The holder 208 is keeping the upper part of the carrier 104 in place. The upper cushion 206 is compressed against the top of the battery pack 108.
In operation, the lock 106 is disengaged, likely through a user-activated mechanism. The disengagement releases the carrier 104, and the pivot hinge 110 is now free to rotate. The weight of the battery pack 108 and the carrier 104 begins to create a moment around the pivot hinge 110, initiating the tilting motion. As the pivot hinge 110 rotates, the carrier 104 begins to pivot outward and upward. The hinge support 220 guides the initial tilting motion, ensuring a controlled movement. As the carrier 104 tilts, the frame hinge 210 begins to articulate, allowing the upper part of the carrier 104 to move independently if needed. The frame hinge 210 on the frame may also rotate, contributing to the overall tilting motion and providing additional support. The holder 208 moves along with the carrier 104, maintaining its grip on the battery pack 108. The upper cushion 206 and the lower cushion 218 flex and adjust to maintain contact with the battery pack 108 throughout the tilting process. The battery pack holder 216 starts to become accessible as the carrier 104 tilts outward. In an implementation, the pivot hinge 110 allows the carrier 104 to tilt to an angle between 30 degrees and 70 degrees relative to the chassis 118 when moving to the accessible position. In another implementation, the pivot hinge 110 enables a compact-access configuration where the carrier 104 tilts between 30 degrees and 45 degrees, ideal for confined spaces such as narrow parking spots or indoor storage areas. A third implementation features an extended-range configuration where the carrier 104 may tilt between 45 degrees and 65 degrees, particularly beneficial for maintenance operations or when maximum accessibility is required. In yet another implementation, the pivot hinge 110 incorporates adjustable stops that allow users to preset preferred tilt angles between 30 degrees and 55 degrees based on their specific needs or physical constraints. An additional implementation includes a multi-stage tilting mechanism where the carrier 104 may be locked at predetermined angles of 30, 45, 60, and 70 degrees, providing optimal positioning for different user heights and accessibility requirements. For specialized applications, an implementation allows for an asymmetric tilt range of 30 degrees to 65 degrees on one side to accommodate unique vehicle designs or specific installation constraints. The tilt range provides accessibility to the battery pack 108, ensuring ease of removal and insertion without requiring excessive force or complex manoeuvres. The adjustable tilt also accommodates various user preferences and two-wheeled electric vehicle 100 designs, enhancing ergonomics and user convenience. Moreover, the tilt angle helps maintain the stability of the during maintenance, reducing the risk of tipping. This controlled range ensures smooth operation, minimizes strain on the hinge mechanism, and protects other components from damage during access.
The tilt stopper 204 engages, preventing further rotation around the pivot hinge 110. The hinge support 220 and the carrier 104 now bear the weight of the battery pack 108 in this angled position. The lock hinge 214 may lock in place to provide additional stability in the accessible position. The handle 222 is fully exposed, allowing for easy gripping and removal of the battery pack 108. The upper cushion 206 and the lower cushion 218 are now in a relaxed state but still in contact with the battery pack 108, providing protection. The pivot hinge 110 serves as the main pivot point and, bears the most stress during the tilting process and likely has a robust construction to handle the weight and repeated movements. The lock hinge 214 allows for articulation of the carrier 104, potentially clearing any obstructions during the tilting process or providing a better angle for battery removal. The frame hinge 210 provides additional support and may help distribute the stress of the tilting motion.
The hinge support 220 acts as a guide rail for the tilting motion, ensuring the carrier 104 follows a predetermined path. The upper cushion 206 and the lower cushion 218 are made of a resilient material that can compress and expand. The upper cushion 206 and the lower cushion 218 protect the battery system 102 from shocks, maintaining its position within the carrier 104 and potentially assisting in the smooth insertion and removal of the battery system 102. The tilt stopper 204 prevents over-tilting, which may potentially cause the battery system 102 to fall out or stress the pivot hinge 110. The tilt stopper 204 engages automatically at the correct angle and may have a shock-absorbing feature to soften the stop at the end of the tilt. The lock 106 is for securing the carrier in the stored position. The lock 106 may have a spring-loaded or otherwise automated re-engagement feature to ensure that the carrier 104 is secured when returned to the stored position. The handle 222 is ergonomically designed and positioned to be easily gripped when the carrier 104 is in the accessible position. The placement of the handle 222 considers the centre of gravity of the battery pack 108 to allow for balanced lifting. The tilting mechanism demonstrates a sophisticated design that balances ease of access, safety, and protection of the battery pack 108. The coordinated movement of multiple hinges, guided by structural elements and controlled by stoppers, allows for a smooth transition that maintains the security of the battery system 102 throughout the process, ensuring smooth and safe access to the battery system 102.
The battery system 102 begins with the battery pack 108 nested within the carrier 104, where their interdependent design enables both secure storage and easy removal. The carrier 104 and the battery pack 108 relationship is enhanced by a multi-point support system including cushions (i.e., the upper cushion 206 and the lower cushion 218), which work in concert with the carrier 104 to provide shock absorption and stability. The tilting mechanism showcases a complex interplay between three hinges, i.e., the pivot hinge 110 at the base initiates the movement, the lock hinge 214 provides intermediate articulation, and the frame hinge 210 on the frame ensures structural stability during transition. The three hinges work synchronously with the lock mechanism and the vertical position holder 212, creating a battery system 102 that is secure yet accessible. The tilt stopper 204 collaborates with the main frame to precisely control the tilting angle between 30 and 70 degrees, while the handle integrates seamlessly with this movement for controlled manipulation. The mechanical symphony extends to the battery's dual-purpose functionality through its emergency power supply interface, where the system transitions from vehicle power source to portable power unit. The weather-resistant seal formed by the gasket around the dedicated access point 112 works in tandem with the structure of the carrier 104 to protect internal components. In the stored position, the integration of the carrier 104 with the chassis 118 creates additional structural rigidity, demonstrating how the battery system 102 contributes to the overall integrity of the two-wheeled electric vehicle 100. The safety interlock mechanism coordinates with the lock 106 and vehicle motion sensors, preventing the battery pack 108 removals during unsafe conditions. When in the accessible position with the tilted carrier, facilitated by rollers and cushioned supports, enabling safe transport. The intricate interdependence culminates in the battery system 102 that achieves secure storage, safe removal, easy transportation, and versatile power supply capabilities, all while maintaining structural integrity and weather protection.

The wheels 224 are positioned at the base of the unit, with the rear wheels likely fixed and the front wheels potentially serving as casters for improved manoeuvrability. With reference to FIG. 3B, there is shown a trolley without battery pack 108.
In operation, the bolt-on trolley is in compact position, the user first extends the handle 222 upward to its full length, providing optimal control height for transportation. The cushioning elements remain in constant contact with the battery pack during movement, absorbing vibrations and protecting the battery from impacts. When moving the battery pack, the user tilts the trolley slightly backwards using the extended handle, allowing the wheels to bear the weight and facilitate smooth rolling movement. The wheels 224 enable easy manoeuvrability across various surfaces, while the bolt-on trolley design ensures the trolley remains securely attached to the battery pack 108 throughout transportation. For storage or when not in use, the bolt-on trolley can be quickly converted to its compact form by retracting the sliding handle. The bolt-on trolley design includes permanent attachment to the battery pack 108 for immediate use, reduced storage space requirements, and elimination of the need to transfer the battery between different carrying devices. The entire system is engineered to provide stable, secure, and efficient transportation of the battery pack while maintaining a user-friendly operation that requires minimal effort for deployment and use.
FIG. 4A is a diagram illustrating the battery system in a stored position, in accordance with an embodiment of another disclosure. FIG. 4A is described in conjunction with elements from FIGs 1 to 3B.
