[0001] DESCRIPTION

[0002] BATTERY RAPID EJECTION MECHANISM

[0003] TECHNICAL FIELD

[0004] The present invention relates to a mechanism that increases the safety of electric and hybrid vehicles by enabling dangerous energy storage and generation systems to be quickly and automatically removed from the vehicle in emergency situations.

[0005] In particular, the invention relates to a mechanism in which a piston rod activated by a signal moves toward the battery, applies pressure on it via a press plate, and then rotates around a pin by means of a bearing, thereby disconnecting the hook attached to the pin and / or continues the movement of the piston rod, contacting the battery and allowing it to move out of the vehicle via a press plate.

[0006] STATE OF THE ART

[0007] Batteries are important devices capable of storing a high amount of electric energy. Today, the most widely used lithium-based batteries are preferred in many portable devices, particularly in electric vehicles, due to their high energy density and long service life.

[0008] Electric vehicles operate with electric motors and are generally powered by batteries; compared to fossil-fueled vehicles, they are less harmful to the environment and attract attention with their low operating costs. Electric vehicles come in various types, such as Battery Electric Vehicles (BEV), Hybrid Electric Vehicles (HEV), and Plug-in Hybrid Electric Vehicles (PHEV), and have become a significant component of sustainable transportation by reducing emissions.One of the major obstacles faced in the widespread adoption of these vehicles is the risks inherent to the battery or battery pack technology used, which gives rise to serious concerns regarding the safety of these energy storage units.

[0009] Currently, not only batteries but also fuel cells used as electrical power sources, electricity generators, and any type of energy storage unit— such as capacitors or supercapacitors— that could serve as alternatives to batteries, must be automatically or voluntarily ejected from the vehicle in emergency situations or at any given time.

[0010] In the current art, there is no direct emergency separation system defined for energy storage or generation units in vehicles. Especially in military vehicles operating in high-risk environments, this absence prevents energy-storing or energy-generating systems from being safely disconnected under critical conditions. This shortcoming increases potential hazards in emergency situations, threatening the safety of both vehicles and occupants.

[0011] Although in the current art there are certain designs aimed at the controlled replacement of batteries, there is no proposed solution for detaching the battery from within the vehicle with a single action and quickly ejecting it. As such, the inability to rapidly remove the battery or energy generation unit during emergencies raises significant safety concerns.

[0012] Conventional fire suppression methods are insufficient to extinguish battery fires. However, fires and thermal runaways can be controlled by proper equipment, preventing environmental hazards. In case of fire or thermal runaway, especially in mobile vehicles, it is difficult to access the necessary equipment and materials quickly. Therefore, removing the battery or energy generation system from the vehicle is an important and required precaution to reduce risk.In today's art, solutions such as cutting off the power during emergencies do not suffice. When energy storage or generation systems sustain damage, they still pose risks such as fire, emission of toxic fumes, release of high-temperature gases, or spark generation. Therefore, simply disconnecting the system is insufficient to completely prevent those threats.

[0013] Methods currently suggested for the controlled removal or replacement of batteries do not offer appropriate solutions for battery ejection in emergency situations. Emergency response windows are narrow, and it is clear that current methods do not meet this critical time requirement. Accordingly, there is a need for a more effective solution allowing the battery to be rapidly and safely removed from the vehicle.

[0014] The separation mechanisms suggested in current art are insufficient as standalone technical solutions for removing the battery from the vehicle. The performance of these mechanisms limits their ability to address emergency situations effectively and poses a serious safety risk. Thus, new mechanisms that can rapidly and effectively remove the battery are essential to eliminate this safety gap.

[0015] The patent publication numbered CN108511650A relates to a structure allowing quick disconnection of battery connectors.

[0016] The patent publication numbered CN211108019U relates to systems that enable fast battery pack replacement under normal operating conditions.

[0017] The patent publication numbered CN211108019U also relates to contact separation mechanisms associated with battery ejection systems.

[0018] Consequently, solving the aforementioned problems present in current technology requires the development of a reliable, economical battery ejection mechanism, and theneed for such a system has necessitated progress in this technical field due to the inadequacy of existing solutions.

[0019] OBJECTIVE OF THE INVENTION

[0020] The present invention relates to a mechanism developed to eliminate the disadvantages mentioned above and introduce new advantages to the related technical field, which increases the safety of electric and hybrid vehicles by enabling dangerous energy storage and generation systems to be quickly and automatically removed from the vehicle in emergency situations.

[0021] The objective of the invention is to provide fast and efficient response capability in emergency events, thanks to its single-point triggering feature. This system enables users to quickly and effortlessly remove energy storage or generation units from the vehicle. Thus, timely safety precautions can be taken without loss of time in an emergency, contributing greatly to minimizing risks.

[0022] The most significant objective of the invention is to provide a structure in which a locking mechanism holding the battery or energy generation unit within the vehicle is released with a single triggering action, and in the continuation of the same action, the battery is shifted outward from the vehicle by the same system. This way, the triggering mechanism both unlocks the battery's connection to the vehicle and also ejects it from the vehicle. As a result, the mechanism subject to the invention offers an effective and structurally simple solution for battery ejection that is easy to produce and assemble.

[0023] Another important objective is to provide a support system for ejecting battery or energy generation units, which are too heavy to be manually moved due to their high capacity. These heavy systems can be ejected from the vehicle without human effort by using the mechanism described in the invention.Another key objective is to minimize unusable dead volumes inside the vehicle that may be caused by the presence of the battery ejection system. There is no need for any gap or external equipment on the lateral surfaces adjacent to the battery's ejection axis. The propulsion system subject to the invention is located on the surface opposite the ejection direction. Similarly, the flexible design allows optimization of interior volume and surface utilization.

[0024] Another goal is for the triggering mechanism to be manually operable when necessary. This capability allows users to manually engage the system in the event of a malfunction or failure of the automatic mechanism. Manual control enhances the operator's authority and ensures fast, accurate responses under emergency conditions.

[0025] Another important goal is that the mechanism is strong enough to withstand all mechanical forces under normal operating conditions without requiring redundant equipment. This reduces both the weight and cost of the system by enabling efficient structural integration.

[0026] The invention also aims to allow the battery or energy storage unit to be placed within a cavity in the vehicle structure. This design lets the vehicle body carry the weight and dynamic loads of the battery or energy generation unit while allowing the mechanism to deal only with the ejection-force loads. This enables the creation of a smaller, simpler, and more cost-effective design.

[0027] An additional objective is to offer design flexibility by allowing either the vehicle structure or the mechanism itself to bear the forces acting on the battery or energy storage unit.

[0028] Another aim is for the mechanism to be activatable in all terrain conditions, including deployment in military vehicles. This versatility improves the functionality of the invention and enables safe operation under various scenarios. In military applicationsespecially, offering an effective solution regardless of terrain or environment is a major benefit, enhancing preparedness.

[0029] Another goal is compatibility with vehicles having different physical architectures. This cross-compatibility enables the invention to be used in various types of vehicles, both in civilian and military contexts, increasing its versatility and sustainability.

[0030] The structural and functional characteristics of the invention and all its advantages can be more clearly understood through the figures given below and the detailed explanation provided with reference to these figures. Therefore, the evaluation of the invention should be made by taking such figures and the detailed explanation into consideration.

[0042] DETAILED DESCRIPTION OF THE INVENTION

[0043] In this detailed description, preferred embodiments of the one-step battery ejection mechanism are disclosed solely for the purpose of better understanding the invention and without imposing any limitations.

[0044] In Figures 1 and 2, the battery ejection mechanism and its components related to the invention are shown in detail. In the invention, under normal operating conditions, the battery (10) remains in a fixed position on the surface following the wall (40), in a configuration where it rests against the wall (40).

[0045] When the battery (10) needs to be ejected from the vehicle, the piston (30), activated by a signal, causes its rod (31) to move towards the battery (10). The piston rod (31) applies pressure to the hook (21) through the press plate (32). Under standard conditions, the hook (21), which is connected to a bearing (20) directly attached to the vehicle body and capable of rotating about the pin (11), starts rotating around the pin (11) under said pressure.

[0046] When the hook (21) opens up to allow the press plate (32) to pass through, its connection with the pin (11) is severed. The piston rod (31) continues its motion, allowing the press plate (32) to contact the battery (10).

[0047] Upon contact of the press plate (32) with the battery (10), the force created by the piston (30) moves the battery (10) outward from the vehicle. When the piston rod (31) travels a distance equivalent to the width of the battery or sufficient to make it fall, all connections between the battery (10) and the vehicle are severed.The mechanism can be designed with a single piston (30), or with additional pistons (30) integrated into the sides of the battery (10) to provide ejection. Furthermore, hook (21) mechanisms can be mounted on both sides of the battery (10). These mechanisms can operate using one or two hooks (21).

[0048] The piston (30) can be actuated by various power sources including hydraulic, pneumatic, electric, or any alternative force mechanisms. The system may also be expanded to be usable manually by human power. These features increase the flexibility of the system and broaden its application potential under different scenarios.

[0049] The protection scope of this application is defined in the claims section and cannot be limited by the examples described above, which are provided solely for illustrative purposes. It is evident that a person skilled in the art can realize variations of the invention based on the disclosed new design or apply the structural configuration to analogous fields within the technical domain.
