Description:FIELD OF THE INVENTION
The invention is primarily related to a simple and robust system of mounting a battery and connecting the same to an electric vehicle. The invention reduces the complexity involved with an integrated mechanical and electrical connectivity while ensuring mechanical connection before operating the vehicle, and reliability.

BACKGROUND OF THE INVENTION
A major issue faced in electric vehicles, especially logistic vehicles where a bigger battery is used, is mounting of the battery and connectivity.

There are many key challenges faced by various OEMs (original equipment manufacturers) in the field of electric vehicle. One of the major problems faced is the battery mounting and connectivity for electric vehicles. Though battery mounting seems simple and easy, proper positioning and securement of the battery in the mounting frame and proper connectivity to the vehicle to generate power to run the vehicle, is a challenge. This becomes even more challenging when the electric vehicle is a logistic vehicle, especially where a much bigger battery is needed.

CN211505638U discloses a battery internal resistance testing arrangement, especially an anchor clamp and test system for testing battery internal resistance. It has a set of anchor clamps having a sharp module that is connected to the probe assembly on the slider part via a sharp module, for testing the internal resistance of a battery. The anchor clamp holder has a lever to tightly hold the battery. The battery module is connected to the probe assembly after securing the battery with the anchor clamp lever for proper connection between the probe and battery.

EP3871968A1discloses a bicycle battery system having a battery tray within which the battery is placed. The battery tray has a latch mechanism consisting of a latch that engages with a cavity provided inside the front end of the battery. The user activates the lock that consists of a plunger and a spring-loaded tab, to place or remove the battery from the bicycle.

To ensure proper positioning and securement of the battery in the vehicle, mechanical clamping which is used for positioning and securing battery to the vehicle and electrical connection means have been integrated as a single structure. However, this often involves use of components with complex design, high manufacturing cost, lack of use of standard components that may result in issues such as securement, safety of the battery, reliability and recurring costs. Another problem with battery mounting in electric vehicles in particular, is integration of mechanical clamping and electrical connection into a single structure. Hence, having separate mechanical and electrical connections would provide a simpler and cost-effective approach. The problems that are faced include non-clamping or improper clamping of the battery by the user after positioning it in the electric vehicle. As the mechanical clamping for the battery and electrical contact are separate, electrical connection can be established directly independent of mechanical clamping, and the vehicle can operate with the battery power. This could result in reduced battery life and damage to the battery.

Also, placement or removal of the battery is tedious and time-consuming.

Hence, there is a strong need for a simple and robust system that will help alleviate the aforementioned issues. Hence, the present invention is focused on providing a solution that is simple, reliable, and cost-effective.

The present invention is aimed at a novel approach whereby it is mandatory for the user to secure the battery to the vehicle before establishing electrical connectivity.

OBJECT OF THE INVENTION
The principal object of the present invention is to ensure proper mounting of battery in an electric vehicle.

Another object of the present invention is to ensure proper electrical connectivity between the battery and electric vehicle.

Yet another object of the present invention is to ensure proper positioning and securement of a battery prior to electrical connectivity in an electric vehicle.

Still yet another object of the present invention is to ensure that electrical connectivity is not possible without completing the mechanical clamping.

Further, another object of the present invention is to enhance the life and mitigate damage to a battery used in an electric vehicle.

Further, yet another object of the present invention is to ensure that battery securement means and electrical connection means are kept separate so as to keep the design simple and robust.

SUMMARY OF THE INVENTION
The present invention deals with a simple, cost-effective and reliable system of securing a battery and establishing electrical connectivity in an electric vehicle.

Present invention is related to a battery mounting system for an electric vehicle that has a separate electric connection means and securement means to simplify the design which is not integrated in a single design, economical and reliable. Said device includes a battery mounting system, wherein the battery is properly positioned and secured by a mechanical clamping means to prevent it from disengaging, and an electric connection means to the battery can be accomplished only after proper mechanical clamping of the battery to the vehicle body or chassis is complete.

The battery mounting system of the present invention comprises an interconnection between the mechanical clamping means and electric connection means to provide electrical connection to the battery upon positioning and securement of the battery to the vehicle.

DETAILED DESCRIPTION OF THE INVENTION
The present invention is related to a simple battery mounting system comprising separate mechanical clamping means and electrical connection means.

According to a first embodiment of the present invention, the battery mounting system (1) comprises, a mechanical structure (2) for housing a battery, base of said mechanical structure (3), a mechanical clamping means (4), and an electrical connection means comprising an electrical connector (5). Said mechanical clamping means (4) in accordance with this embodiment of the present invention is a toggle clamp (4a) with a lever (6).

The battery is housed in the mechanical structure (2) and fixed to the base of the mechanical structure (3) with the help of a toggle clamp (4a) to ensure proper positioning and securement of said battery. Said toggle clamp (4a) is a pull-action clamp which can be pressed down to create a locked position. The mechanical structure (2) is fixed to the chassis of the electric vehicle. The electrical connector (5) is positioned such that, electrical connection of the battery with the vehicle can be established only through access to said electrical connector (5) when said toggle clamp (4a) is engaged and mechanical clamping is achieved. The electrical connector (5) is blocked by a lever (6a) when the toggle clamp (4a) is not engaged and the mechanical clamping is incomplete, thereby disabling access of electrical connector (5) to the battery.

A toggle clamp, also called as quick clamp, or a quick release clamp, or an over-center clamp, etc., is a fastening device that usually consists of a handle, a holding bar, a linkage system of pivot pins, and one or more levers. The handle is used to control the device, the holding bar is used to grip the workpiece, and the handle is used to boost the applied force. Once the engagement of the workpiece is made, the toggle clamp locks. The toggle clamp typically serves to secure an object tightly in order to prevent it from moving or disengaging upon application of pressure.

As shown in Fig. 1, the battery mounting system (1) comprises a battery, a mechanical structure (2) to house said battery, base of said mechanical structure (3), a toggle clamp (4a), and an electrical connector (5). Said toggle clamp (4a) is arranged on the mechanical structure (2), and functions as a means for locking and unlocking said mechanical structure (2) after positioning the battery in said mechanical structure (2).

According to the embodiments of the present invention, as shown in Fig. 1 to Fig. 6, the battery is mechanically clamped to the base of the mechanical structure (3) via a toggle clamp (4a). The toggle clamp as shown in Fig. 3, consists of a lever (6a) that is used as a handle to activate the toggle clamp (4a) to operate said mechanical structure (2) in open (Fig. 1, Fig. 2 and Fig. 3) and close (Fig. 4, Fig. 5 and Fig. 6) positions. The electrical connector (5) is positioned such that, the electrical connector (5) is accessible only when the toggle clamp (4a) is engaged. If the toggle clamp (4a) is not engaged, the electrical connector (5) is blocked, and the electrical connection is not achieved. Said toggle clamp (4a) is bolted to the chassis of the vehicle. When a user positions the battery in the mechanical structure (2), it is mandatory for the user to complete the mechanical clamping using the toggle clamp (4a) to enable access of electrical connector (5) and thereby establish electrical connection between the battery and vehicle. Said toggle clamp (4a) does not allow the electrical connectivity of the battery with the electrical connector (5) in the open position. The electrical connector (5) is blocked by a lever (6a) when the toggle clamp (4a) is not engaged and securement of battery is incomplete, thereby not allowing establishment of electrical connection with the battery. Said electrical connectivity to the electrical connector (5) is achieved only when the toggle clamp (4a) is in the closed position.

According to another embodiment of the present invention, the toggle clamp (4b) as shown in Fig. 7, comprises of a lever (6b) that is used as a handle to activate the toggle clamp (4b) to operate said mechanical structure (2) in open (Fig. 7, Fig. 8 and Fig. 9) and close (Fig. 10, Fig. 11 and Fig. 12) positions. Said toggle clamp (4b) is positioned on one side of the mechanical structure (2). Said toggle clamp (4b) is a vertical hold down or press type toggle clamp that presses said mechanical structure (2) downwards. The electrical connector (5) is positioned such that, the electrical connector (5) is accessible only when the toggle clamp (4b) is engaged. If the toggle clamp (4b) is not engaged, the electrical connector (5) is blocked, and the electrical connection is not achieved. Said toggle clamp (4b) is bolted to the chassis of the vehicle. When a user positions the battery in the mechanical structure (2), it is mandatory for the user to complete the securement of the battery to the vehicle using said toggle clamp (4b) and access the electrical connector (5), and thereby establish electrical connection between the battery and vehicle. Said toggle clamp (4b) does not allow electrical connectivity between the battery and the electrical connector (5) in the open position. Access to the electrical connector (5) is blocked by a lever (6b) when the toggle clamp (4a) is not engaged and securement of battery is incomplete, thereby disabling access of electrical connector (5) to the battery. Said electrical connectivity to the electrical connector (5) is accessible only when the toggle clamp (4b) is in the closed position. Said toggle clamp (4b) according to this embodiment not only blocks and establishes access of the electrical connector (5) with the battery, but is also arranged such that, it moves fully out of the mechanical structure (2) so that the battery can be easily positioned in said mechanical structure (2) and can also be easily removed.

According to another embodiment of the present invention, as shown in Fig. 13 to Fig. 18, the battery mounting system (1) comprises a battery, a mechanical structure (2), base of said mechanical structure (3), a toggle clamp (4c) with a lever (6c), an electrical connector (5), a toggle lock u-shaped rod (7), and a switch (8). Said battery (1) is secured to the base of the mechanical structure (2) using a toggle clamp (4c). Said toggle lock u-shaped rod (7) is integrated with said mechanical structure (2). Said switch (8) is present near the toggle lock u-shaped rod (7). Said switch (8) may be for example, a spring-loaded electric switch, and is connected in series with said electrical connector (5), such that electricity will flow through said switch (8).

Fig. 13 to Fig. 15 show the toggle clamp (4c) in an unlocked position. In this position, when the toggle clamp (4c) is not locked, the switch (8) is not pressed and does not allow electricity flow through said switch (8). When said switch (8) is in an open position, it is not pressed by said toggle lock u-shaped rod (7), thereby disabling connectivity with said electrical connector (5) and electrical connection between said battery and vehicle. As the connection is incomplete, the supply of power from the battery to the vehicle is disabled.

Fig. 16 to Fig. 18 show the toggle clamp (4) in a locked position. In this position, when the toggle clamp (4c) is locked, the switch (8) is in a pressed position thus enabling electricity to flow through the switch (8). When said switch (8) is in a closed position, it is pressed by said toggle lock u-shaped rod (7), thereby enabling connectivity with said electrical connector (5) and establishing electrical connection between said battery and vehicle. Once the connection is complete, the power supply from the battery to the vehicle is established. Said battery mounting system (1) in accordance with the embodiments of the present invention, is designed such that said toggle clamp (4c) must be in a locked position to enable proper positioning and securement of battery to the vehicle, and the switch (8) must be in a pressed position to enable supply of power from the battery to the vehicle. It is to be understood that said toggle clamp (4c) is not only in contact with said switch (8), but is also in contact with said toggle lock u-shaped rod (7) to transfer the mechanical load to said toggle u-shaped rod (7) thereby enabling the flow of electricity through the switch (8).

According to another embodiment of the present invention, as shown in Fig. 19 to Fig. 22, the battery mounting system (1) comprises a battery, a mechanical structure (2), base of said mechanical structure (3), an electrical connector (5), a mounting plate (9) with a slot (10), a plunger pin assembly (11) comprising one or more plunger pins (12), a plunger (13), and a plunger support (14).

Said battery (1) in accordance with this embodiment is connected to the base of the mechanical structure (3), and said plunger pin assembly (11) is integrated with said mechanical structure (2). Said mechanical structure (2) also includes a mounting plate (9) with a slot (10) for receiving said plunger pin (12). Said plunger pin assembly (11) comprises a plunger (13) such as a spring-loaded plunger, and is provided on a plunger support (14). Said plunger pin (12) is positioned such that, it blocks the electrical connector (5) until it is properly engaged in the slot (10) provided on the mounting plate (9). When the plunger pin (12) is properly positioned in the slot (10) of the mounting plate (9), the electrical connector (5) is accessible and the electrical connection between the battery and electrical connector (5) is established, thus enabling supply of power from the battery to the vehicle.

As shown in Fig. 19 and Fig. 20, the plunger pin assembly (11) is in an open position. In this position, the plunger pin (12) does not engage with the slot (10) of the mounting plate (9) and blocks the electrical connector (5), thereby disabling electrical connection and supply of power from the battery to the vehicle.

As shown in Fig. 21 and Fig. 22, the plunger pin assembly (11) is in a closed position. In this position, the plunger pin (12) engages with the slot (10) of the mounting plate (9), and the electrical connector (5) is accessible and the electrical connection is established, thereby enabling supply of power from the battery to the vehicle.

It is to be understood that, the plunger pin assembly (11) may comprise one or more plunger pins that will engage with one or more slots of the mounting plate (10).

According to another embodiment of the present invention, the battery mounting system (1) comprises one or more toggle clamps (4d-i and 4d-ii), as shown in Fig. 23 to Fig. 28, a handle bar (15) that is used as a handle to activate the toggle clamps (4d-i and 4d-ii), levers (6d-i and 6d-ii) to operate said mechanical structure (2) in open (Fig. 23, Fig. 24 and Fig. 25) and closed (Fig. 26, Fig. 27 and Fig. 28) positions. Said toggle clamps (4d-i and 4d-ii) are positioned on either side of the mechanical structure (2). Said toggle clamps (4d-i and 4d-ii) are press type toggle clamps that press said mechanical structure (2) downwards with the help of said handle bar (15). The electrical connector (5) is positioned such that, the electrical connector is accessible only when both the toggle clamps (4d-i and 4d-ii) are engaged. If the toggle clamps (4d-i) and/or (4d-ii) are disengaged, the electrical connector (5) is blocked, and the electrical connection is not achieved. Said toggle clamps (4d-i and 4d-ii) are fastened to the chassis of the vehicle. In accordance with the embodiment of the present invention, when a user positions the battery in said mechanical structure (2), it is mandatory for the user to complete the securement of the battery to the vehicle using said toggle clamps (4d-i and 4d-ii), to enable access to the electrical connector (5). Said toggle clamps (4d-i and 4d-ii) do not allow the electrical connectivity between the battery and said electrical connector (5) when in an open position. Access to the electrical connector (5) is blocked by a lever (6d-i) when the toggle clamps (4d-i) and/or (4d-ii) are disengaged and securement of battery is incomplete, thereby disabling access to said electrical connector (5) thus leading to disablement of electrical connection between the battery and the vehicle. Said electrical connectivity to the electrical connector (5) is accessible only when the toggle clamps (4d-i and 4d-ii) are in the closed position. Said toggle clamps (4d-i and 4d-ii) in accordance with the embodiment of the present invention, not only block or allow access to the electrical connector (5) for disabling or enabling electrical connection between the battery and the vehicle, but are also arranged such that, they move fully out of said mechanical structure (2) so that the battery can be easily positioned in or removed from said mechanical structure (2).

The battery mounting system according to this embodiment of the present invention is such that said toggle clamps (4d-i and 4d-ii) provide good mechanical clamping of the battery, thereby reducing vibration and fatigue to the battery, and increasing battery life while also enabling a single hand operation using the handle bar (15). This alleviates the problem of the need for the user to go to the other side of the mechanical clamping means to lock the other toggle in instances where the size of the battery is large.

In accordance with the various embodiments of the present invention, the battery mounting system (1) comprises a battery, a mechanical structure (2) to house said battery, base of said mechanical structure (3), a mechanical clamping means (4), and an electrical connection means comprising an electrical connector (5). Said mechanical clamping means (4) is a toggle clamp (4a, 4b, 4c, or 4d-i and 4-d-ii), or a plunger pin assembly (11). Said mechanical clamping means (4) is arranged on said mechanical structure (2), and functions as a means for locking and unlocking said mechanical structure (2) after positioning the battery in said mechanical structure (2) to secure the battery and establish electrical connection. As demonstrated by various embodiments of the present disclosure, proper positioning and securement of batteries in electric vehicles may effectively be achieved using separate securing means and electrical connection means, and use of one or more toggle clamps either standalone or in conjunction with a switch (8), or a plunger pin assembly (11). Proper positioning and securement of the battery is achieved only when said toggle clamp (4a, 4b, 4c, or 4d-i and 4-d-ii) is in a closed position, and permits establishment of electrical connection between the battery and vehicle. In accordance with the embodiments of the present invention, electrical connection between the battery and the vehicle can be established only upon proper positioning and securement of said battery. Upon establishment of electrical connection between the battery and the vehicle, power is supplied for operating the vehicle.

The battery mounting system of the present invention has an advantage of securing the battery safely in the mechanical structure (2), thereby enhancing the life of the battery and in turn life of the vehicle.

The battery mounting system of the present invention also has an advantage of use of off-the-shelf parts that simplifies the architecture of the battery that is used in an electric vehicle.

It is to be understood, however, that the present invention would not be limited by any means to the components, arrangements and materials that are not specifically described, and any change to the components, variations, and modifications can be made without departing from the spirit and scope described in the present invention. , C , Claims:I/We claim:
