The present application claims priority from Indian Provisional Patent Application No. 202221075291 filed on 25/12/2022, the entirety of which is incorporated herein by a reference.
TECHNICAL FIELD
The disclosure relates to a frame assembly for vehicle. Particularly, the present disclosure relates to an arrangement for mounting a battery compartment on a chassis of an electric vehicle (EV),.
BACKGROUND
The domain of electric vehicles (EVs) is rapidly expanding as the world shifts towards more sustainable and environmentally friendly modes of transportation. Central to the operation of EVs is battery pack, which provides the necessary power to drive the vehicles. The integration of the battery pack within the vehicle are critical to the performance of vehicle and also to the ease of use and maintenance. However, the mounting of battery packs in EVs has been associated with challenges that impede the practicality and user experience.
In the traditional setup, battery packs are often mounted within a fixed compartment of the chassis of EV. Such placement is typically selected to balance the weight distribution of vehicle and to protect the battery from environmental factors and collision impacts. While fixed batteries benefit from a stable center of gravity, the stationary nature poses significant challenges in terms of charging infrastructure requirements and the complexity of replacement or upgrades. Drivers are often constrained by the location of charging stations, which can impact the practicality of EV use, especially on longer journeys or in areas with inadequate charging infrastructure.
Removable battery packs offer an alternative to this, allowing for more flexible charging options, including battery swapping facilities that can reduce vehicle downtime. However, the removal and replacement process can be physically demanding and time-consuming. The battery packs are typically heavy and housed in compartments that are not always easily accessible, requiring considerable physical effort to extract and replace them.
Additionally, the mounting mechanisms for the batteries are often intricate, involving multiple fasteners or connectors that secure the battery to the vehicle. The complexity of the systems can make the installation process cumbersome and may require specialized tools or expertise. Users who attempt to remove or install battery packs without proper knowledge or equipment risk damaging the battery or vehicle, and possibly harming themselves.
The connection interfaces between the battery pack and the power management systems of vehicle also present difficulties. Ensuring a secure and reliable electrical connection is important for the operation of vehicle. Poorly designed connectors can lead to increased resistance, charging inefficiencies, and even safety hazards such as electrical shorts or fires.
Furthermore, as battery technology advances and the capacity of battery packs increases to provide longer range and better performance, the size and weight of the batteries also increase. Such trend exacerbates the existing challenges of battery mounting, requiring even more robust mounting systems to handle the additional mass. The integration of smart technology into battery systems offers some promise, with the potential for automated mounting and dismounting mechanisms that could simplify the process. Yet, the technologies are still in the infancy and are yet to be widely adopted in the market.
Given the importance of battery packs in EVs, and the myriad of challenges associated with the mounting, there is a clear and pressing need for development in the space. The development of more efficient and user-friendly battery mounting systems to enhance the usability and appeal of EVs, addressing one of the key barriers to the widespread adoption.
Thus, there is an urgent need for further development in the field of technology to enable efficient mounting of battery packs to improve the user experience.

FIG. 1 illustrates a front view of an arrangement 100 for mounting a battery compartment on a chassis/frame 102 of an electric vehicle (EV), in accordance with the embodiments of the present disclosure. The arrangement 100 comprises a vehicle frame 102, a mounting member 112 and other known components of a battery mounting arrangement/apparatus.
In an embodiment, the vehicle frame 102 comprises at least one upper frame member 104 and at least one lower frame member 106. The upper frame member 104 and the at least one lower frame member 106 provide structural support and stability to the vehicle frame 102, facilitating the secure attachment and precise alignment of the battery compartment within the chassis of EV. The upper frame member 104 is situated in a position that optimizes the center of gravity of EV when the battery pack is installed, thereby contributing to the overall balance and handling characteristics of the EV. Meanwhile, the lower frame member 106 is positioned to provide additional support and to withstand the stresses and strains encountered during vehicle operation, including the dynamic forces exerted during acceleration, deceleration, and maneuvering. The cooperation between the upper frame member 104 and the lower frame member 106 is instrumental in maintaining the structural integrity of the vehicle frame 102 while also providing a reliable foundation for the battery compartment. The vehicle frame 102, comprising the upper frame member 104 and the lower frame member 106, accommodates the size, shape, and weight of the battery compartment, ensuring that the battery compartment remains securely housed within the vehicle under a range of operating conditions. The arrangement of the at least one upper frame member 104 and at least one lower frame member 106 within the vehicle frame 102 serves to protect the battery compartment from environmental elements and the rigors of daily use, while also allowing for efficient heat dissipation and accessibility for maintenance or replacement of the battery pack.
In an embodiment, the at least one lower frame member 106 comprises a first section 108 and a second section 110, which are integrally formed to support the structural integrity required for the operational demands of the EV. The structure of the first section 108 and the second section 110 allows for an optimized balance between structural resilience and flexibility, enabling said vehicle frame 102 to withstand various stresses and strains encountered during the operation of the EV. Additionally, the first section 108 and the second section 110 accommodate the specific geometric and spatial constraints of the design of EV, ensuring compatibility with a range of battery compartment sizes and shapes.
In an embodiment, the arrangement 100 includes the mounting member 112 that is disposed between the first section 108 and the second section 110 of at least one lower frame member 106 of the vehicle frame 102. The lower frame member 106 is an integral part of the vehicle frame 102 and provides structural support for the battery compartment as well as for the vehicle frame 102 itself.
In an embodiment, the first section 108 and the second section 110 are spaced apart at a predetermined distance to accommodate the mounting member 112 within the interstitial space defined therebetween. Such configuration facilitates a pivotal connection between the battery compartment and the vehicle frame 102, enabling the battery compartment to move relative to the chassis. The mounting member 112 includes pivotal coupling means which are constructed to permit the pivotal movement of the battery compartment between a first position, generally aligned with the vehicle frame 102 during normal operation of the EV, and a second position (i.e., tilted position relative to frame 102), which allows for easier access to the battery compartment for service or exchange of the battery pack contained therein.
In an embodiment, the mounting member 112 serves as a pivotal axis for the battery compartment, allowing the battery compartment to rotate or tilt relative to the longitudinal axis of the vehicle frame 102. Such pivotal movement of the battery compartment is of particular utility when facilitating the mounting and dismounting of the battery pack from the vehicle frame 102, during battery swapping/replacement/repair by providing additional space without dismantling the EV. In the first position, the battery compartment is secured in a stable orientation for vehicular operation, with the battery pack securely housed within. In the second position, the battery compartment is tilted or pivoted away from the first section 108 and the second section 110 of the at least one lower frame member 106, providing improved ergonomic access for maintenance personnel or automated systems to remove, replace, or service the battery pack.
In an embodiment, the mounting member 112 provides a secure and stable support for the battery compartment while still allowing for the requisite pivotal movement.

The mounting member 112 integrates seamlessly with the configurations of vehicle frame 102, providing a versatile solution that can be adapted to a variety of EV designs.
In an embodiment, the arrangement 100 may include locking means associated with the mounting member 112 to secure the battery compartment in both the first position and second position. Such locking means engages automatically or manually to prevent unintentional movement of the battery compartment during vehicle operation or during the battery servicing process. The mounting member 112 can support the weight of the battery compartment and withstand the dynamic forces experienced during the operation of the EV. The dimensions and material specifications of the mounting member 112 are thus selected to provide a balance between strength, weight, and durability.
In an embodiment, the mounting member 112 may incorporate additional features to facilitate the engagement and disengagement of the battery compartment from the mounting member 112. The features may include, but are not limited to, guide rails, rollers, or bearings that reduce friction and wear during the pivotal movement of the battery compartment. The arrangement 100 may further comprise a motorized or manual actuation system to control the pivotal movement of the battery compartment. Such actuation system may be operatively connected to the mounting member 112 and to effectuate the movement of the battery compartment between the first position and second position.
In an embodiment, the mounting member 112 includes damping or cushioning means to reduce shock and vibration transmitted to the battery compartment during the operation of the EV. Such feature is particularly beneficial to extend the service life of the battery pack and to ensure the reliable operation of the EV. The arrangement 100 comply with applicable safety standards and regulations for EVs. The mounting member 112, pivotal coupling means, and any associated locking, actuation, damping, or cushioning systems are constructed to meet or exceed the safety requirements for on-road vehicles.
In an embodiment, the first section 108, the second section 110 and the mounting member 112, may be configured in a co-axial arrangement. The first section 108 and the second section 110 of the at least one lower member 106 align along a common axis with the mounting member 112, thereby providing a streamlined structural integration with the chassis of the EV. The co-axial configuration facilitates a uniform distribution of load and a balanced structural support for the battery compartment when mounted onto the vehicle frame 102. The co-axial arrangement ensures that when the battery compartment is engaged with the vehicle frame 102, the first section 108, the second section 110, and mounting member 112 contributes to the overall rigidity and stability of the mounting system. The co-axial design maintains the integrity of the connection between the battery compartment and the vehicle frame 102 during the dynamic conditions of vehicle operation, such as during acceleration, deceleration, and traversing over uneven terrain. Furthermore, the co-axial arrangement of the first section 108, the second section 110, and mounting member 112 simplifies the assembly process of the battery compartment onto the vehicle frame 102, enabling a more efficient manufacturing and maintenance process.
In an embodiment, the at least one of the first section 108, the second section 110, or the mounting member 112 may comprise a rotational element that facilitates the pivoting of the mounting member 112 with respect to the vehicle frame 102. The incorporation of the rotational element within the vehicle frame 102 permits the battery compartment to transition between a mounted state and an unmounted state, wherein the battery compartment is capable of rotation relative to the vehicle frame 102. The rotation enables a user to more easily access the battery compartment for maintenance, replacement, or upgrading of the battery pack housed within. The rotational element supports the weight of the battery compartment and the battery pack, providing a secure connection while allowing for rotational movement. Furthermore, the rotational element withstands the mechanical stresses associated with the rotation and the vibrational forces encountered during the operation of the EV. The rotational elements may include bearings, pivots, rotatable joints, or swivels integrated within the first section 108, the second section 110, or the mounting member 112. The rotational elements are essential for imparting the pivotal movement required for the mounting member 112 to rotate in relation to the vehicle frame 102. Bearings could facilitate smooth rotation and support heavy loads, while pivots would allow for a fixed axis of rotation. Rotatable joints could provide flexibility in the angle of rotation, and swivels would enable the battery compartment to rotate through multiple axes, enhancing accessibility.
In an embodiment, the arrangement 100 for mounting the battery compartment on the chassis may include a locking mechanism to constrains the movement of the rotational element. The locking mechanism selectively secures the mounting member 112 in a stationary position relative to the at least one lower frame member 106. The locking mechanism operates by engaging with corresponding features on the rotational element and the lower frame member 106, thereby preventing undesired motion that could compromise the integrity of the position of battery compartment or the safety of the battery pack housed within. The locking mechanism delivers a reliable method for maintaining the battery compartment in a fixed orientation during the operation of EV, ensuring that the battery pack remains securely mounted within the confines of the vehicle frame 102. In addition, the locking mechanism affords the user the capability to release the mounting member 112 when access to the battery compartment is required, such as for maintenance, inspection, or replacement of the battery pack. Upon activation of the release feature of the locking mechanism, the mounting member 112 can be moved to a different position, thus allowing the battery compartment to be accessed with ease.
In an embodiment, the mounting member 112 may feature at least one mounting bracket, which is integral to the connection between the battery compartment and the mounting member 112, facilitating secure attachment and proper alignment within the vehicle frame 102. The mounting bracket conform to the contours and specifications of the vehicle frame 102, ensuring a stable fit for the operational stability of the EV. The mounting bracket within the mounting member 112 is optimized to bear the weight of the battery compartment, as well as to withstand the dynamic forces that are encountered during the operation of vehicle, including but not limited to vibrations, accelerations, and decelerations. The mounting bracket is devised to allow for ease of access and convenience in maintenance procedures, where the battery compartment may require to be detached from or reattached to such vehicle frame 102. The mounting bracket within the mounting member 112 accommodates the maintenance activities without compromising the structural integrity of the vehicle frame 102 or the safety of the battery compartment.
In an embodiment, the mounting member 112 may comprise an adjustable tension control, which regulates the ease of rotation in relation to the attachment of battery compartment to the chassis of the EV. The adjustable tension control, incorporated within the mounting member 112 allows for precise adjustments in the tension level, thereby facilitating a controlled and customizable rotational movement of the battery compartment. The mounting member 112 ensures that the tension control can be finely tuned to accommodate varying requirements of the positioning and stability of battery compartment on the EV chassis. Furthermore, the implementation of the adjustable tension control within the mounting member 112 contributes significantly to the overall durability and operational efficiency of the EV by enabling a secure yet adaptable connection between the battery compartment and the EV chassis. The integration of the adjustable tension control in the mounting member 112 is achieved through a series of mechanical components, which are constructed and arranged to provide an effective and reliable means of tension adjustment. The arrangement of mechanical components is particularly advantageous in scenarios where the battery compartment requires frequent repositioning or when the EV is subjected to different driving conditions that necessitate varying degrees of battery compartment stability.
In an embodiment, the mounting member 112 and/or at least one lower frame member 106 may comprise a drive unit to rotate the battery compartment. Specifically, the mounting member 112 is formed with, or securely affixed to, the chassis, providing a stable connection. The drive unit, incorporated into the mounting member 112 and/or said at least one lower frame member 106 facilitates a controlled and precise rotation of the battery compartment. Such feature is essential for various operational needs, such as maintenance, battery replacement, or optimizing the weight distribution of EV for improved performance and stability. Utilizing materials of high structural integrity, yet lightweight, the construction of the mounting member 112 and the at least one lower frame member 106 ensures both the resilience and efficiency of the arrangement 100. The mounting member 112 and/or said lower frame member 106 with the integrated drive unit also allows for a seamless incorporation into chassis, preserving the aesthetic appeal and aerodynamic efficiency of EV.
In an embodiment, the first section 108 may comprise a first extended segment that extend outwardly in the direction of the mounting member 112. In a harmonious complement to the first section, the second section 110 incorporates a second extended segment. The second segment, akin to the counterpart in the first section 108, extends outwardly towards the mounting member 112. The design is further exemplified by the interaction between the first and second extended segments and the mounting member 112. The first segment and the second segment are adjacent to the mounting member 112 and are engaged with the mounting member 112 in a manner that facilitates pivotal rotation. The pivotal rotation capability of the mounting member 112 is a key aspect of the arrangement 100, offering a dynamic and flexible connection that significantly contributes to the overall functionality of the battery compartment mounting system of EV. The passive engagement between the extended first segment, the extended second segment and the mounting member 112 ensures a secure yet adaptable connection, allowing for efficient assembly and maintenance while also accommodating the various stresses and demands typical of EV operation.
In an embodiment, the mounting member 112 may comprise a primary extended portion, which is disposed at a primary end of the mounting member 112. The primary extended portion facilitates a connection between the mounting member 112 and the first section 108 of the arrangement 100. Additionally, a secondary extended portion is disposed at a secondary primary end of the mounting member 112, which is located at the opposite end of the primary end. The secondary extended portion is similarly integral to maintaining a secure attachment of the mounting member 112 to the second section 110 of the arrangement 100. Both the primary extended portion and the secondary extended portion are constructed to enable pivot rotation of the mounting member 112 with respect to each of the first section 108 and the second section 110. The pivotal feature is essential for allowing a degree of flexibility in the positioning and orientation of the battery compartment in relation to the chassis of the EV. The pivotal rotation facilitated by the primary and secondary extended portions ensures that the mounting member 112 can adapt to various configurations and requirements of EV.
In an embodiment, the arrangement 100 may comprise a longitudinal element, which passes through the first section 108, the second section 110, and the mounting member 112. The longitudinal enables pivotal rotation of the mounting member 112 with respect to each of the first section 108 and the second section 110. The pivotal rotation facilitated by the longitudinal element allows the mounting member 112 to adapt to various operational demands, including but not limited to, the adjustment for optimal positioning and alignment of the battery compartment within the chassis of the EV. Furthermore, the arrangement 100 is configured such that the longitudinal element allows for rotational movement and also ensures a secure and stable connection between the mounting member 112 and the first section 108 and the second section 110. Such configuration is paramount in maintaining the integrity of the battery compartment, particularly under dynamic conditions such as movement or vibration of the EV.
FIG. 2 presents a three-dimensional isometric view that exemplifies the tilted positioning of a battery compartment in relation to the vehicle frame, in accordance with the embodiments of the current disclosure. The illustration demonstrates the battery compartment having been pivoted into a tilted orientation through rotation of the mounting member 112. Such an arrangement is paramount for the facilitation of the mounting or dismounting process of battery pack. The pivotal action imparted by the mounting member 112 allows the battery compartment to be maneuvered with ease, enhancing accessibility for maintenance or replacement procedures. Such configuration ensures that the battery pack can be serviced with minimal effort and disruption to the structural integrity of EV. The transformation of the battery compartment to the tilted position is indicative of the practical application of the mounting member 112 in contributing to the efficiency and user-friendliness of the design of EV.
Optionally, the arrangement 100 comprises a U-shaped enclosure that partially or fully encloses the adjustable tension control (e.g., hydraulic damper) and battery compartment. For example, the U-shaped enclosure is disposed such that edges of the U-shaped enclosure are disposed parallely/co-planarly with a front face of the battery compartment and a back portion of the U-shaped enclosure is disposed behind a rear face of the battery compartment. Further, the hydraulic damper is arranged between the rear face of the battery compartment and the curved portion of the U-shaped enclosure. Consequently, such disposing of the hydraulic damper within the U-shaped enclosure enables to protect the hydraulic damper and/or the battery compartment from shocks transmitted to the chassis during operation of the electric vehicle while also providing support to the battery compartment during pivoting of the battery compartment.
Fig. 3 describes a top-perspective view of the frame 102, in accordance with the embodiments of the current disclosure. As shown, the frame 102 comprises one or more upper frame member 104 (for exemplary purpose two upper frame members 104 are depicted) and at least one lower frame member 106 (for exemplary purpose two lower frame members 106 are depicted), wherein the at least one lower frame member 106 comprises first section 108 and second section 110. The first section 108 and second section 110 are spaced apart at a predetermined distance to accommodate the mounting member 112 (which receive battery pack compartment, not shown) within the interstitial space defined therebetween. As illustrated, first section 108, the second section 110 and the mounting member 112 are configured in co-axial arrangement. The co-axial configuration facilitates a uniform distribution of load and a balanced structural support for the battery compartment when mounted onto the vehicle frame 102.
