Description

Technical Field

[0001] The present disclosure generally relates to a battery release system for a vehicle, and more particularly, to a battery release system whereby a battery is released from a vehicle and separated from the vehicle in an emergency situation. Background Art

[0002] Due to the influence of environmental regulations, environmentally friendly vehicles, such as electric vehicles, hybrid vehicles, and fuel cell vehicles, each of which is driven by an electric motor, have proliferated throughout the world.

[0003] Such environmentally friendly vehicles include hybrid electric vehicles (HEV), battery electric vehicles (BEV), fuel cell electric vehicles (FCEV), and the like.

[0004] A plug-in hybrid electric vehicle (PHEV) is called a hybrid electric vehicle, and both the PHEV and the BEV are electric vehicles in which electric power is received from outside the vehicle to charge a battery.

[0005] These environmentally friendly vehicles have a common feature that they are provided with a motor as a driving device and a battery for supplying power to the motor.

[0006] If a fire occurs in a battery in an eco-friendly vehicle, the fire could spread quickly due to the internal structure of the battery and its components. Extinguishing fires in batteries in eco-friendly vehicles is difficult using existing fire extinguishing devices used in internal combustion engine vehicles.

[0007] In internal combustion engine vehicles, the fuel used is a flammable material, there are many heat sources, and various wires are entangled, so the risk of fire always exists.

[0008] For example, since the engine room of a vehicle is equipped with a high-temperature engine and various electrical devices, a fire may occur if the engine and the electrical devices are damaged, or if a malfunction occurs due to a vehicle collision.

[0009] In addition, there is a risk of fire in the engine compartment due to engine overheating during driving or during exhaust gas aftertreatment.

[0010] As a conventional fire extinguishing device in a vehicle, a fire extinguisher is provided. However, if the driver fails to use the fire extinguisher in time, the initial fire extinguishing may fail and the fire may spread to the entire vehicle.

[0011] Furthermore, public transportation vehicles such as buses carry many passengers, so fire management for passenger safety is crucial, and failure in the initial response to a fire may result in injury and / or death.

[0012] In addition, since the driver is inside the vehicle while driving, it is often impossible to quickly notice a fire in the engine compartment before a large amount of smoke is generated. Unlike passenger cars, the engine compartment of a bus is usually located at the rear of the bus, making it difficult for the driver to notice a fire in the engine compartment of a bus.

[0013] Therefore, in the early stages of a fire, the driver cannot quickly extinguish the fire and the fire may spread, which may cause the vehicle to burn and increase the risk of injury to passengers.

[0014] In addition, even when a driver or a passenger in a vehicle quickly realizes the occurrence of a fire, it is difficult to quickly extinguish the fire at an early stage by only using a small fire extinguisher provided in the vehicle.

[0015] Therefore, there is known a fire extinguishing system in which, when a fire is detected in an engine room of a vehicle, a fire extinguishing agent is automatically sprayed toward the fire point so as to extinguish the fire quickly at an early stage.

[0016] In a known engine room fire extinguishing system, when a fire occurs in the engine room, a fire detection signal is sent thereto, and high-pressure nitrogen loaded in a nitrogen tank is supplied to a gas cylinder filled with a fire extinguishing agent through a hose.

[0017] Therefore, in the gas cylinder, when the piston is operated by high-pressure nitrogen, the internal fire extinguishing agent is supplied to the injection line under high pressure by the thrust of the piston, and finally the fire extinguishing agent is injected into the fire point through the nozzle of the injection line to extinguish the fire.

[0018] However, although the above-mentioned fire extinguishing system helps to automatically extinguish a fire by automatically spraying a fire extinguishing agent in an engine room of a vehicle or other space in the vehicle, it is difficult to apply the system to extinguishing a fire occurring in a battery pack of an environmentally friendly vehicle.

[0019] Generally, in the case of a battery pack, when a fire occurs, it is almost impossible to extinguish the fire by simply spraying water or a fire extinguishing agent onto the battery pack.

[0020] The battery pack contains ignition materials within its enclosed internal space, and the battery cells that make up the battery pack contain materials with a large amount of oxygen inside. Therefore, due to the residual oxygen inside the battery pack, when a fire occurs in the battery pack, it is difficult to completely extinguish the fire by using water or spraying a fire extinguishing agent (fire extinguishing powder or fire extinguishing liquid), such as those used in conventional internal combustion engine vehicles.

[0021] Therefore, when a fire occurs in the battery of a vehicle, it may not be possible to completely extinguish the fire, and after some time, the fire may spread to the vehicle.

[0022] In recent years, as the use of environmentally friendly vehicles has increased, the risk of fire due to external impact or internal short circuits in batteries or surrounding high-voltage wires has also increased.

[0023] However, so far, there is no technology that can prevent a fire that occurs in a battery from spreading to the entire vehicle, and thus there are risks such as vehicle combustion or passenger injury. Summary of the Invention

[0024] Therefore, the present disclosure proposes a technology that can prevent vehicle combustion or personal injury caused by fire occurring in a battery.

[0025] To achieve the above objectives, according to one embodiment of the present disclosure, a battery release system for a vehicle is provided, which includes: a controller that outputs a control signal to release a battery pack from the vehicle, so that when the controller determines that a fire has occurred in the battery pack, the battery pack is separated from the vehicle; a mounting frame that is mounted to the vehicle body to support the battery pack; and a first locking device that is mounted to the mounting frame to lock the battery pack to the mounting frame so that the battery pack remains on the mounting frame, and the first locking device is operated to release the locked state of the battery pack in response to the control signal of the controller, so that the release of the battery pack is performed.

[0026] The battery release system for a vehicle according to an embodiment of the present disclosure may further include a fire detection sensor that detects a fire occurring in the battery pack, wherein the controller is configured to determine whether a fire has occurred in the battery pack based on a signal from the fire detection sensor.

[0027] In addition, the battery release system for a vehicle according to an embodiment of the present disclosure may further include: an operating device for being operated by a user to release the battery pack; and a second locking device mounted to the mounting frame to lock the battery pack to the mounting frame so that the battery pack remains on the mounting frame, and the second locking device is operated to release the locked state of the battery pack according to the user's manipulation of the operating device due to the connection between the second locking device and the operating device.

[0028] In addition, the battery release system for a vehicle according to an embodiment of the present disclosure may further include a notification device operated by the controller to notify a user of a fire occurring in the battery pack.

[0029] Furthermore, the manipulation device may include a release lever for manipulation by a user, and a release cable connected between the release lever and the second locking device to transmit a manipulation force of the user from the release lever to the second locking device.

[0030] In addition, the mounting frame may include: a base frame that supports the lower portion of the battery pack and is combined with the lower portion of the battery pack via a first locking device; and an upper frame that is combined with the base frame and supports the battery pack on an upper side of the battery pack and is combined with the battery pack via a second locking device.

[0031] Additionally, the base frame may include a pair of sub-frames for supporting a lower portion of the battery pack at opposite sides of the battery pack, each sub-frame being configured to support a lower portion of each opposite end of the battery pack in a longitudinal direction of the battery pack via a first locking device.

[0032] In addition, the first locking device may include: a hook that holds and locks a clamping claw portion provided on a lower portion of the battery pack; and an actuator that is fixedly mounted to each sub-frame, wherein the actuator is connected to the hook and, in response to a control signal output from the controller, forcibly rotates the hook that holds the clamping claw portion in a locked state to a position where the hook releases the clamping claw portion from being in a locked state.

[0033] In addition, the second locking device may include: a first connector fixedly mounted to an upper surface of the battery pack; a second connector fixedly mounted to the mounting frame; and a clamp that clamps and engages the first connector and the second connector with each other and releases the engagement state between the first connector and the second connector by using a user's operating force transmitted from the operating device.

[0034] In addition, the first connector may include: a base plate fixed to the upper surface of the battery pack; a column arranged on the base plate by extending upward from the base plate; and a connecting plate arranged on the upper part of the column, the connecting plate having a disc shape extending in the radial direction of the disc, and the second connector may include: a base plate fixed to the mounting frame; a column arranged on the base plate by extending downward from the base plate; and a connecting plate arranged on the lower part of the column, the connecting plate having a disc shape extending in the radial direction of the disc, wherein the connecting plate of the first connector and the connecting plate of the second connector can be engaged with each other by a clamp when connected to each other.

[0035] In addition, a coupling groove may be provided in one of the connecting plates of the first coupler and the second coupler, and a coupling protrusion may be provided on the remaining one of the two connecting plates to be inserted into the coupling groove.

[0037] In addition, a receiving groove may be provided in the inner circumferential surface of each sub-block so that two connecting plates connected to each other are inserted into the receiving groove.

[0038] In addition, the first locking device may include: a hook that holds and locks a clamping claw portion provided on a lower portion of the battery pack; and an actuator that is fixedly mounted to the mounting frame and, by using a control signal output from the controller, forcibly rotates the hook that holds the clamping claw portion in a locked state to a position where the hook releases the clamping claw portion from being in a locked state.

[0054] Hereinafter, reference will now be made in more detail to exemplary embodiments of the present disclosure, examples of which are shown in the accompanying drawings so that those skilled in the art can effectively perform the embodiments of the present disclosure. However, the present disclosure is not limited to its embodiments and can be implemented in various ways.

[0055] The present disclosure proposes a technology that can prevent a battery mounted on an environmentally friendly vehicle from catching fire and causing vehicle combustion or personal injury.

[0056] As described above, in the event of a fire occurring in the battery pack 1 of an environmentally friendly vehicle, extinguishing the fire by spraying a fire extinguishing agent onto the burning parts has limitations.

[0057] Therefore, in order to prevent the fire from spreading to the vehicle, a method of separating the burning parts from the vehicle can be considered, and separating the burning parts from the vehicle can protect the vehicle and the driver from being harmed by the fire.

[0058] When a fire occurs in a battery pack in a vehicle, the battery pack is automatically released from the vehicle so that the battery pack can be separated from the vehicle and removed therefrom.

[0059] To this end, the present disclosure relates to a system that can release a battery from a vehicle so that the battery can be separated and removed from the vehicle when a fire occurs in the battery. The system responds to a control signal from a controller that detects a fire in the battery and operates through driver manipulation, and releases the state of the battery mounted to the vehicle body to release the battery from the vehicle body so that the battery can be separated from or removed from the vehicle.

[0060] In this disclosure, a battery may refer to a battery in a battery pack unit, ie, a battery pack.

[0061] In addition, the present disclosure can be applied to environmentally friendly vehicles. Specifically, although the present disclosure can be applied to general passenger vehicles, the present disclosure is useful when applied to commercial vehicles, particularly battery-electric trucks and battery-electric buses, and hydrogen-electric trucks and hydrogen-electric buses equipped with fuel cells.

[0062] In the case of a truck or bus, since the vehicle body is large, the battery pack 1 may be mounted on the vehicle body, which is exposed to the outside, rather than being mounted inside the vehicle. Therefore, when the battery release system of the present disclosure is applied, it is possible to release the battery pack 1 in which a fire has occurred from the vehicle, so that the battery pack 1 can be separated from the vehicle and removed therefrom.

[0063] Furthermore, in the case of a bus with a large number of passengers, failure to extinguish the fire initially could result in multiple injuries. Therefore, when initial fire extinguishing is difficult, separating the battery from the vehicle to prevent the fire from spreading to the vehicle may be more effective in preventing a major disaster than extinguishing the battery fire.

[0064] Furthermore, if initial fire extinguishing fails in a bus with many passengers, many casualties may result. Therefore, when initial fire extinguishing is difficult, separating the battery from the vehicle to prevent the fire from spreading to the vehicle may be more effective in preventing many casualties than extinguishing the battery fire.

[0065] That is, since the battery, which may be a source of vehicle fire, can be separated from the vehicle, it is possible to reliably prevent more dangerous situations such as vehicle combustion or personal injury.

[0066] Hereinafter, the configuration of a battery release system according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0067] Figure 1 is a block diagram showing a main configuration of a battery release system according to an embodiment of the present disclosure, Figure 2is a perspective view illustrating a battery release system according to an embodiment of the present disclosure.

[0068] Figure 3 is a side view showing an operating state of the first locking device 40 in the battery release system according to an embodiment of the present disclosure, Figure 4 is a perspective view showing the configuration of the operating device 50 and the second locking device 60 in the battery release system according to the embodiment of the present disclosure;

Figure 8 1 shows a state where two sub-blocks 71a and 71b constitute the jig 70 which are combined with each other in a circular shape to be engaged with each other by an engaging pin 75, Figure 9 A state in which the two sub-blocks 71 a and 71 b are opened by the elastic restoring force of the spring 79 is shown.

[0075] Figure 10 It is a sectional view showing a clamp 70 of a second locking device in a battery release system according to an embodiment of the present disclosure, and is a sectional view showing a state of a connecting plate 68 of a second connector and a connecting plate 64 of a first connector engaged with each other by the clamp 70, wherein the connecting plate 68 and the connecting plate 64 are combined with each other.

[0076] The battery release system according to the present disclosure is configured to integrally perform the functions of mounting the battery pack 1 to the vehicle body and releasing the mounting of the battery pack 1 to the vehicle body frame 2 and removing the battery pack 1 from the vehicle frame to separate and remove the battery pack 1 from the vehicle.

[0077] Regarding the construction of the battery release system, the battery release system according to the present disclosure includes: a controller 20, which determines whether a fire occurs in the battery pack 1; a mounting frame 30, which is mounted to the vehicle body to support and mount the battery pack 1 to the mounting frame; and a first locking device 40, which is mounted to the mounting frame 30, operates the first locking device to lock the battery pack 1 to the mounting frame so that the battery pack remains on the mounting frame, and releases the locked state of the battery pack 1 in response to a control signal of the controller 20, so that the release of the battery pack 1 is performed.

[0078] In addition, the battery release system according to the present disclosure may further include a fire detection sensor 10 that detects a fire in the battery pack 1 , and a notification device 80 that is operated by the controller 20 to notify that a fire has occurred in the battery pack 1 .

[0079] In addition, the battery release system according to the present disclosure may further include: an operating device 50 for being operated by a user to release the battery pack 1; and a second locking device 60, mounted to the mounting frame 30 to lock the battery pack 1 to the mounting frame, so that the battery pack remains on the mounting frame, and due to the connection between the second locking device 60 and the operating device 50, the locked state of the battery pack 1 is released according to the user's manipulation of the operating device 50.

[0080] In an embodiment of the present disclosure, the manipulation device 50 may include a lever 51 (hereinafter referred to as a “release lever”) for manipulation by a user and a power transmission device that transmits the user's manipulation force from the release lever 51 to the second locking device 60 .

[0081] In the embodiment of the present disclosure, the power transmission device may be a cable (hereinafter referred to as a “release cable”) connected between the release lever 51 and the second locking device 60 .

[0082] Therefore, the first locking device 40 is a device that electrically releases the locked state of the battery pack 1 , and in particular, is manipulated to release the locked state of the battery pack 1 by controlling the controller 20 that detects a fire.

[0083] On the other hand, the second locking device 60 is a device that allows the locked state of the battery pack 1 to be manually released by manipulation by a user (e.g., a driver), and operates to allow the locked state of the battery pack 1 to be released by the manipulation device 50 when the user manipulates the manipulation device 50, so as to separate the battery pack 1 from the vehicle after a fire is recognized.

[0084] In the embodiments of the disclosure, the first locking device 40 and the second locking device 60 are coupled to the battery pack 1 in the mounting frame 30 and are components that lock the battery pack 1 to the mounting frame, while the battery pack 1 is maintained and supported on the vehicle via the mounting frame in the locked state of the battery pack.

[0085] In addition, the first locking device 40 and the second locking device 60 are components that are separate from the battery pack 1, so that the battery pack 1 is released from the mounting frame during release of the locked state of the battery pack 1. The state in which the battery pack 1 is locked to the mounting frame 30 can be completely released, and only when the first locking device 40 and the second locking device 60 both release the locked state of the battery pack 1, the battery pack 1 can be separated from the mounting frame 30 to be released from the mounting frame 30.

[0086] In the embodiments of the disclosure, the release of the battery pack 1 indicates that the battery pack is separated from the vehicle by falling from the mounting frame 30 due to the weight of the battery pack, so that the spread of fire to the vehicle is prevented.

[0087] In addition, the release of the locked state of the battery pack 1 by the first locking device 40 and the second locking device 60 indicates that elements that can interfere with the free fall of the battery pack 1 of the configuration of the disclosure and the configuration of the first locking device 40 and the second locking device 60 are removed from the battery pack 1.

[0088] Reference Figure 1 , a fire detection sensor 10 that detects a fire in the battery pack 1, a controller 20 that determines whether a fire occurs in the battery pack 1 by receiving a signal of the fire detection sensor 10, an actuator 41 of the first locking device 40 that operates in response to a control signal of the controller 20, and a notification device 80 that is operated by the controller 20 are shown.

[0089] In the embodiments of the disclosure, the fire detection sensor 10 can be a temperature sensor that measures the temperature of the battery pack 1 and outputs a signal according to the measured value.

[0090] The fire detection sensor 10 is connected to the controller 20 so as to transmit a signal thereto, and the controller 20 can receive the signal output from the fire detection sensor 10 and determine whether a fire occurs in the battery pack 1 based on the temperature of the battery pack indicated by the signal.

[0091] In the embodiments of the disclosure, the controller 20 can be set to determine that a fire occurs in the battery pack 1 when the temperature of the battery pack measured by the fire detection sensor 10 is at least a preset reference temperature.

[0092] In addition, when the controller 20 determines that a fire has occurred in the battery pack 1 , the controller 20 outputs a control signal for releasing the battery pack, and the actuator 41 of the first locking device 40 performs an operation of releasing the battery pack in response to the control signal of the controller 20 .

[0093] In addition, when the controller 20 determines that a fire occurs in the battery pack based on the signal of the fire detection sensor 10 and when the vehicle speed is less than or equal to a reference speed, the controller 20 may be configured to output a control signal for releasing the battery pack.

[0094] In this case, the reference speed may be determined as a stationary vehicle speed at which the vehicle can be determined to be in a stopped state, for example, 0 km / h. Therefore, the battery pack 1 can be released in the case of a fire detection state of the battery pack and a stopped state of the vehicle.

[0095] In addition, when the controller 20 determines that a fire has occurred in the battery pack 1, the controller 20 operates the notification device 80 and notifies the user (driver) of the fire occurrence in the battery pack 1, where the battery pack is in a state locked by the first locking device 40, so that the user can recognize the fire occurrence in the battery pack 1.

[0096] Next, the user determines whether to actually release the battery pack 1 , and when the user finally decides to release the battery pack 1 , the user manipulates the manipulation device 50 to further release the state of the battery pack locked by the second locking device 60 .

[0097] Finally, when the locking performed by the first locking device 40 and the second locking device 60 is released, the battery pack 1 is released from the mounting frame 30 and separated from the vehicle.

[0098] In an embodiment of the present disclosure, the notification device 80 may be one of a sound output device, a display device, or a lamp mounted to the vehicle, which provides notification of fire occurrence in response to a control signal output from the controller 20 .

[0099] Here, the sound output device may be a buzzer installed inside or outside the vehicle, the display device may be a display installed in the instrument panel or an in-vehicle display such as an AVN display, and the lamp may be a warning light installed in the instrument panel or installed inside or outside the vehicle.

[0100] In the embodiment of the present disclosure, the mounting frame 30 is a structure in which the battery pack 1 is mounted in a vehicle, and may be a part of the vehicle body, or may be a frame that is manufactured separately from the vehicle body and then fixed to and combined with a side of the vehicle body.

[0101] In the drawings, the vehicle body is not shown except for the mounting frame 30. The mounting frame 30 may be mounted at a position on the vehicle body from which the battery pack 1 reaches the ground without being disturbed by obstacles when the battery pack 1 vertically falls due to the release of the locking performed by the first locking device 40 and the second locking device 60, and this position may be set as the mounting position of the battery pack.

[0102] For example, for a truck, the mounting frame 30 may be mounted and fixed to a side surface of a vehicle body frame, which is longitudinally arranged toward the front and rear of the vehicle in a lower portion of the vehicle body.

[0103] In an embodiment of the present disclosure, the mounting frame 30 may include: a base frame 31 supporting the lower portion of the battery pack 1; and an upper frame 32 supporting the battery pack 1 at the upper side of the battery pack, wherein the base frame 31 and the upper frame 32 may be combined with each other to form an integral frame.

[0104] In the locked state of the battery pack 1 , the base frame 31 is combined with the lower portion of the battery pack 1 through the first locking device 40 to support the lower portion of the battery pack 1 .

[0105] In an embodiment of the present disclosure, the battery pack 1 may be supported by the base frame 31 , wherein a lower portion of the battery pack 1 is located on the first locking device 40 , ie, the battery pack 1 is loaded on the first locking device 40 .

[0106] In the locked state of the battery pack 1 , the upper frame 32 is combined with the upper portion of the battery pack 1 by the second locking device 60 , and the battery pack 1 may be supported by the upper frame 32 , wherein the battery pack 1 is suspended on the upper frame 32 via the second locking device 60 .

[0107] like Figure 2 As shown, the base frame 31 may include a pair of sub-frames 31a and 31b, which are used to support the lower portion of the battery pack 1 at opposite sides of the battery pack, wherein each of the sub-frames 31a and 31b is configured to have a "U" shape and a first locking device 40 is provided at its lower end portion.

[0108] In addition, the lower end portion of each of the sub-frames 31a and 31b is configured to support the lower portion of the battery pack 1 via the first locking device 40. In particular, each of the two sub-frames 31a and 31b located on opposite sides of the battery pack 1 can be used to support the lower portion of each opposite end portion of the battery pack 1 located in the longitudinal direction of the battery pack via the first locking device 40.

[0109] To this end, the battery release system according to the present disclosure has a pair of first locking devices 40, which perform locking and release simultaneously in response to a control signal of the controller 20, such as Figure 2As shown, each of the first locking devices 40 is used to support each lower end portion of the battery pack 1 in the longitudinal direction of the battery pack, wherein each of the first locking devices 40 is mounted on the lower end portion of the corresponding sub-frame 31a and 31b.

[0110] The upper frame 32 may be a frame having a plate shape horizontally arranged to connect the pair of sub-frames 31 a and 31 b to each other, and opposite ends of the upper frame 32 may be integrally fixed to the sub-frames 31 a and 31 b.

[0111] Thus, a space having a predetermined height from the upper frame 32 to the lower end of the base frame 31 is provided, and the battery pack 1 is located in the space to be installed. In this case, the upper frame 32 can be coupled to the middle portion of the upper surface of the battery pack 1 in the upper portion of the battery pack via the second locking device 60 (see FIG. Figure 2 ).

[0112] The first locking device 40 is mounted to each of the sub-frames 31a and 31b of the base frame 31. In particular, the first locking device 40 is rotatably mounted to the base frame 31. Figure 3 The lower end portion of each of the sub-frames 31a and 31b shown may include: a hook 43 that holds and locks the clamping claw portion 1a of the lower portion of the battery pack 1; and an actuator 41 that is fixedly mounted to each of the sub-frames 31a and 31b and forcibly rotates the hook 43 that holds the locked state of the clamping claw portion 1a to a position where the hook releases the locked state of the clamping claw portion.

[0113] Here, the hook 43 has a hinge pin 44 integrally provided thereon, and is rotatably coupled to a block 42 fixedly mounted to a lower end portion of each of the sub-frames 31 a and 31 b via the hinge pin 44 .

[0114] In an embodiment of the present disclosure, the actuator 41 may be a motor, and driving of the motor is controlled in response to a control signal from the controller 20. In particular, the actuator 41 may be a servo motor.

[0115] In this case, the driving shaft of the motor 41 is connected to the hinge pin 44 of the hook 43, and during the driving process of the motor 41, the rotational force of the motor is transmitted to the hinge pin 44 of the hook 43 via the driving shaft, so that the hook 53 can rotate.

[0116] The motor 41 is driven by the controller 20, which detects a fire in the battery pack 1 and forcibly rotates the hook 43 in the unlocking direction of the hook. Thus, the state of the battery pack 1 locked by the first locking device 40 is released.

[0117] In the present disclosure, the base frame 31 includes a pair of sub-frames 31a and 31b, and in this case, each of the two sub-frames 31a and 31b needs to independently support and lock the battery pack 1. Therefore, each of the first locking devices 40 having the same configuration is mounted to the two sub-frames 31a and 31b.

[0118] In addition, the two first locking devices 40 mounted to each of the sub-frames 31 a and 31 b are simultaneously operated to unlock the battery pack 1 in response to a control signal output from the controller 20 .

[0119] Next, we will refer to Figures 4 to 10 The configurations of the operating device 50 and the second locking device 60 will be described.

[0120] The operating device 50 is operable by a user, such as a driver, to release the battery pack 1. To release the battery pack 1, after the state of the battery pack locked by the first locking device 40 is automatically released by the controller 20 detecting a fire in the battery pack, the user recognizes the fire in the battery pack through the notification device 80 and releases the state of the battery pack locked by the second locking device 60 by operating the operating device 50.

[0121] In the present disclosure, both the first locking device 40 and the second locking device 60 are devices for locking the battery pack 1 to the mounting frame 30 so that the battery pack 1 is retained on the mounting frame. Therefore, the locked state of the battery pack 1 is completely released, and the battery pack can be released only when the state of the battery pack 1 locked by the first locking device 40 is released and then the state of the battery pack 1 locked by the second locking device 60 is also released.

[0122] In an embodiment of the present disclosure, the manipulation device 50 may include a release lever 51 provided at one side of the vehicle to be manipulated by a user, and the power transmission device transmits the user's manipulation force from the release lever 51 to the second locking device 60 .

[0123] Here, the power transmission device may be a release cable 52 connected between the release lever 51 and the second locking device 60 .

[0124] The release lever 51 may be provided at a predetermined position in the vehicle (eg, a driver's seat), and rotatably mounted to a lever housing 51 a fixed to the vehicle.

[0125] In addition, the release cable 52 can be connected from the release lever 51 to the second locking device 60 via the multi-cable box 54, and can include a tube 53a for connecting between fixed elements located in the path of the release cable and a wire 53b for moving along the inside of the tube 53a, a first end of which is connected to the release lever 51 and a second end of which is connected to the second locking device 60, so that the wire is pulled in conjunction with the rotation operation of the release lever 51.

[0126] like Figure 4 and Figure 5 As shown, the tube 53 a of the release lever 51 is used to connect between the lever housing 51 a and the housing 54 a of the multi-cable box 54 , and between the housing 54 a of the multi-cable box 54 and the second coupler 65 of the second locking device 60 .

[0127] In this case, the wire 53b provided by being inserted into the inside of the tube 53a is used to connect between the release lever 51 and the connection plate 55 in the multi-cable box 54, and between the connection plate 55 in the multi-cable box 54 and the clamp 70 of the second locking device 60.

[0128] More specifically, with the wire 53 b passing through the base plate 66 of the second coupler 65 , the wire 53 b extends to the jig 70 on the lower side of the base plate 66 and is connected to the engaging pin 75 of the jig 70 .

[0129] Here, the lever housing 51 a , the housing 54 a of the multi-cable box 54 , and the second coupler 65 of the second locking device 60 are all fixed elements fixedly mounted to the vehicle so as not to move and operate.

[0130] The multi-cable box 54 is used to divide the release cable 52 connected to one release lever 51 into a plurality of release cables. In the embodiment of the present disclosure, the battery release system having the same configuration can be applied to a plurality of battery packs 1, and in this case, the release lever 51 can be commonly used.

[0131] In this case, in order to connect the release cable 52 between one release lever 51 and the plurality of second locking devices 60 , the release cable 52 may be divided into the release cables 52 by the multi-cable box 54 , and the release cable 52 may be connected to the plurality of second locking devices 60 .

[0132] Therefore, when the user manipulates the release lever 51, the plurality of second locking devices 60 connected to the release cables 52 are simultaneously operated to unlock the plurality of battery packs 1. The release cables 52 may be divided into the release cables 52 by the multi-cable box 54. Therefore, the plurality of battery packs 1 can be simultaneously unlocked and released from the mounting frame.

[0133] refer to Figure 4 and Figure 5 , an example can be seen in which one release cable 52 connected to the release lever 51 is divided into two release cables 52 by the multi-cable box 54. Therefore, when one release lever 51 is manipulated, the locking performed by the two second locking devices 60 is released at the same time, and the two battery packs 1 can be simultaneously unlocked and released from the mounting frame.

[0134] refer to Figure 5The connection plate 55 is used to move up and down within the housing 54a of the multi-cable box 54, one release cable 52 connected to the release lever 51 is connected to the first side of the housing 54a of the multi-cable box 54 and the connection plate 55, and two release cables 52 connected to the second locking device 60 are connected to the second side of the housing 54a of the multi-cable box 54 and the connection plate 55.

[0135] In addition, the tube 53a of each release cable 52 is connected to the housing 54a of the multi-cable box 54. In this case, the wire 53b within the tube 53a of each release cable 52 is considered to be connected to the connection plate 55.

[0136] When the release lever 51 is manipulated by pulling, the wire 53b of the release cable 52 connected to the upper side of the connection plate 55 is pulled, and the connection plate 55 is pulled up in Figure 5 In this case, the wires 53b of the two release cables 52 connected to the lower side of the connection plate 55 are pulled at the same time.

[0137] Therefore, the lock performed by the two second locking devices 60 whose ends are connected to the wires 53b of the release cables 52 located at the lower side of the connection plate 55 is released at the same time, and finally, the two battery packs 1 are unlocked and released from the mounting frame at the same time. Figure 5

[0138] In Figure 4 and Figure 5 An embodiment in which one release cable 52 is divided into two release cables 52 is shown, but this is for illustrative purposes, and the present disclosure is not limited thereto. Considering the number of battery packs 1 as a target, the release cable 52 can be divided into three or four release cables.

[0139] In addition, when the vehicle has a plurality of battery packs 1, a plurality of release levers 51 can also be provided. In this case, after the driver checks the battery pack 1 in which a fire has occurred, the driver pulls only the release lever 51 required among the plurality of release levers 51 to manipulate, so that the locked state of the battery pack 1 in which a fire has occurred can be released.

[0140] Next, the second locking device 60 installed to the upper frame 32 of the mounting frame 30 holds the battery pack 1 on the mounting frame by locking the battery pack 1, and since the second locking device 60 is connected to the manipulation device 50, the battery pack 1 is unlocked during the user manipulates the manipulation device 50.

[0141] ​In an embodiment of the present disclosure, the second locking device 60 may include: a first connector 61, which is fixedly mounted to the upper surface of the battery pack 1; a second connector 65, which is fixedly mounted to the upper frame 32 of the mounting frame 30; and a clamp 70, which clamps the first connector 61 and the second connector 65 and engages them with each other by using the user's operating force transmitted from the operating device 50, and releases the engagement state between the first connector 61 and the second connector 65.

[0142] like Figure 4 As shown, the first connector 61 may include: a base plate 62, which is fixed to the upper surface of the battery pack 1 by being combined with the upper surface thereof; a column 63, which is provided on the base plate 62 by extending so as to protrude upward from the base plate 62; and a connecting plate 64, which is provided on the upper portion of the column 63 and has the shape of a disc extending in the radial direction of the disc.

[0143] The second connector 65 may include: a base plate 66, which is connected to the upper frame ( Figure 2 a column 67, which is provided on the base plate 66 by extending so as to protrude downward from the base plate 66; and a connecting plate 68, which is provided on the lower portion of the column 67 and has the shape of a disk extending in the radial direction of the disk.

[0144] In an embodiment of the present disclosure, the base plate 62 of the first connector 61 may be joined and fixed to the upper surface of the battery pack 1 by bolt connection, and the base plate 66 of the second connector 65 may be joined and fixed to the lower surface of the upper frame 32 by bolt connection.

[0145] In the embodiment of the present disclosure, when the battery pack is mounted to the base frame 31 of the mounting frame 30 to be supported during the installation of the battery pack 1, the first coupler 61 provided on the battery pack 1 is combined and engaged with the second coupler 65 mounted to the upper frame 32 of the mounting frame 30. In this case, as shown in FIG. Figure 10 As shown, the connecting plate 64 of the first coupling and the connecting plate 68 of the second coupling are engaged with each other and are simultaneously connected to each other.

[0146] That is, when the battery pack 1 is supported by the base frame 31 , the connecting plate 64 of the first coupler 61 mounted to the battery pack 1 is engaged with the connecting plate 68 of the second coupler 65 mounted to the upper frame 32 by the clamp 70 , wherein the connecting plate 64 and the connecting plate 68 are connected to each other.

[0147] In an embodiment of the present disclosure, the connecting plate 64 of the first connector 61 and the connecting plate 68 of the second connector 65 connected to each other during installation of the battery pack 1 are combined with each other by a groove-projection structure, which allows easy installation of the battery pack 1 and engagement by the clamp 70.

[0148] That is, a coupling groove 69 is formed in one of the connecting plates 64 and 68 of the first and second couplings 61 and 65 , and a coupling protrusion 64 a is formed on the remaining one of the two connecting plates to be inserted into the coupling groove 69 .

[0149] refer to Figure 6 、 Figure 7 and Figure 10 , a coupling groove 69 is formed in the connection plate 68 of the second coupler 65 mounted to the upper frame 32 , and a coupling protrusion 64 a is formed on the connection plate 64 of the first coupler 61 mounted to the battery pack 1 .

[0150] Alternatively, the coupling groove may be formed in the connection plate 64 of the first coupling 61 , and the coupling protrusion may be formed on the connection plate 68 of the second coupling 65 .

[0151] The clamp 70 is used to keep the connecting plate 64 of the first connector 61 and the connecting plate 68 of the second connector 65 connected to each other by covering the connecting plate 64 and the connecting plate 68, and is composed of two sub-blocks 71a and 71b, a hinge part 76 and a coupling pin 75, wherein the two sub-blocks 71a and 71b are hinged to each other by the hinge part 76.

[0152] In this case, the state of the two sub-blocks 71 a and 71 b being clamped to each other is maintained by the engagement pin 75 between the first coupling 61 and the second coupling 65 .

[0153] Each of the sub-blocks 71a and 71b of the clamp 70 may have a circular ring shape. In this case, the circular clamp 70 may be constructed to include each of the two sub-blocks 71a and 71b having a semicircular shape, and the end of each of the two sub-blocks 71a and 71b may be constructed to be rotatable relative to the hinge portion 76.

[0154] When the connection plates 64 and 68 of the two couplings 61 and 65 having a circular shape are connected to each other at the lower position and the upper position, respectively, the two sub-blocks 71a and 71b are configured to cover the entirety of the two connection plates 64 and 68. Therefore, the two connection plates 64 and 68 are integrally combined with each other and clamped to each other by the two sub-blocks 71a and 71b.

[0155] In an embodiment of the present disclosure, receiving grooves 72a and 72b are provided in the inner circumferential surfaces of the sub-blocks 71a and 71b so that approximately half of each of the two connecting plates 64 and 68 are connected to each other, that is, a semicircular portion of each of the two connecting plates 64 and 68 can be accommodated in each receiving groove.

[0156] In addition, the ends of the sub-blocks 71a and 71b opposite to the ends of the sub-blocks 71a and 71b are hinged to each other in the sub-blocks 71a and 71b, that is, the front end portions of the sub-blocks 71a and 71b have stepped joint portions 73a and 73b formed therein. When the two sub-blocks 71a and 71b are rotated relative to the hinge portion 76 and the clamp 70 is formed into a circular shape, the joint portions 73a and 73b of the two sub-blocks 71a and 71b are configured to be combined with each other in the lower position and the upper position.

[0157] In the present disclosure, the pin holes 74a and 74b are provided in the engaging portions 73a and 73b of each of the sub-blocks 71a and 71b by being formed therein. Here, when the two sub-blocks 71a and 71b are combined with each other so that the jig 70 forms a circular shape, that is, when the engaging portions 73a and 73b of the two sub-blocks 71a and 71b are combined with each other, the pin holes 74a and 74b are directly formed by the two engaging portions 73a and 73b located on the lower and upper sides.

[0158] The engaging pin 75 is inserted into the pin holes 74 a and 74 b so that the two engaging portions 73 a and 73 b engaged with each other are integrally combined with each other, and the end of the release cable 52 of the manipulation device 50 is connected to the engaging pin 75 .

[0159] Therefore, when the user pulls and rotates the release lever 51 of the operating device 50, the engaging pin 75 is pulled, and at the same time, the release cable 52 is pulled. Therefore, the engaging pin 75 is removed from the pin holes 74a and 74b of the two sub-blocks 71a and 71b, and the engaged state of the two sub-blocks 71a and 71b can be released.

[0160] In this case, the two sub-blocks 71a and 71b are opened while being rotated by the elastic restoring force of the spring 79 provided in the hinge portion 76. In this case, the two connecting plates 64 and 68 inserted into the receiving grooves 72a and 72b of the two sub-blocks 71a and 71b are removed from the receiving grooves 72a and 72b, and the engagement state between the two connecting plates 64 and 68 is released, and further the engagement state between the first coupler 61 and the second coupler 65 is released.

[0161] Therefore, when the clamp 70 releases the engagement state between the two couplings 61 and 65, the state of the battery pack 1 locked by the second locking device 60 is released. Finally, the first coupling 61 attached to the battery pack 1 is in a state of being separated from the second coupling 65 attached to the upper frame 32 of the mounting frame 30. Next, the battery pack 1 falls due to its weight, and the release of the battery pack can be performed.

[0162] In the embodiment of the present disclosure, the hinge portion 76 may be a known hinge rotatably coupled between the two sub-blocks 71 a and 71 b of the jig 70 .

[0163] In this case, the hinge portion 76 may be a hinge having a spring 79 disposed therein. When the two sub-blocks 71a and 71b are formed into a circular shape so that the two connecting plates 64 and 68 are engaged with each other, the spring 79 is in a deformed state. Next, when the engaging pin 75 is removed from the pin holes 74a and 74b, the spring 79 provides the elastic restoring force required to rotate the two sub-blocks 71a and 71b in the direction of opening the two sub-blocks 71a and 71b.

[0164] That is, the hinge portion 76 may be constructed by including a hinge box 77, a hinge pin 78, and a spring 79. In this case, the hinge box 77 is constructed by being divided into two parts integrally formed into two sub-blocks 71a and 71b, and the hinge pin 78 is inserted between the two parts of the hinge box 77 to combine the two parts with each other.

[0165] In addition, the spring 79 may be provided between the two sub-blocks 71a and 71b, or between the two separated parts of the hinge box 77. When the engaging portions 73a and 73b of the two sub-blocks 71a and 71b are engaged with each other by the engaging pin 75 and the engaging portions 73a and 73b of the two sub-blocks 71a and 71b are combined with each other, the spring 79 is converted into a compressed state, and then when the engaging pin 75 is removed from the pin holes 74a and 74b of the engaging portions 73a and 73b, an elastic restoring force is applied to the two sub-blocks 71a and 71b, and the two sub-blocks 71a and 71b rotate in the opening direction.

[0166] Thus, the configuration of the battery release system according to the embodiment of the present disclosure has been described. Although the operating state of the battery release system has been described together with the above configuration, the operating state will be summarized again below.

[0167] First, the controller 20 detects occurrence of fire in the battery pack 1 by using a signal of the fire detection sensor 10 , and outputs a control signal for removing the battery pack 1 from the vehicle when the vehicle is stopped.

[0168] Next, the servo motor 41 as the actuator of the first locking device 40 is driven in response to the control signal of the controller 20, and the servo motor forcibly rotates the hook 43 downward. Next, the state of the battery pack 1 locked by the first locking device 40 is released.

[0169] At the same time, the controller 20 operates the notification device 80 and notifies that a fire has occurred in the battery pack 1 , and after a user (eg, a driver) recognizes the fire occurrence in the battery pack 1 through the notification device 80 , the user manipulates the manipulation device 50 to perform release of the battery pack 1 .

[0170] In this case, the user manipulates the release lever 51 by pulling the release lever 51 , and the wire 53 b of the release cable 52 is pulled by the rotation of the release lever 51 .

[0171] Therefore, when the release cable 52 is pulled, the engagement pin 75 is pulled upward, which causes the two sub-blocks 71 a and 71 b to engage with each other in the clamp 70 of the second locking device 60 .

[0172] In this case, the engaging pin 75 is removed from the pin holes 74a and 74b formed in the sub-blocks 71a and 71b of the clamp 70 and separated from the two sub-blocks 71a and 71b. Therefore, the sub-blocks 71a and 71b are rotated in the opening direction by the elastic restoring force of the spring 79 in the hinge portion 76.

[0173] Therefore, the connecting plate 64 of the first coupling 61 and the connecting plate 68 of the second coupling 65 are simultaneously removed from the receiving grooves 72a and 72b of the two sub-blocks 71a and 71b, and the clamped and engaged state between the first coupling 61 and the second coupling 65 by the clamp 70 is released. Finally, the state of the battery pack 1 locked by the second locking device 60 is released.

[0174] Finally, the locking performed by the first locking device 40 and the second locking device 60 is completely released, and the battery pack 1 falls downward by its weight. As a result, the connecting plate 64 of the first coupling 61 and the connecting plate 68 of the second coupling 65 are separated from each other, and the battery pack 1 is released from the vehicle's mounting frame 30 and completely separated from the vehicle.

[0175] As described above, after the battery pack in which the fire occurred has been released from the vehicle, the motor of the vehicle is driven by the power source of another battery pack in which the fire did not occur, and thus the vehicle can move away from the released battery pack 1 .

[0176] Therefore, even when a fire occurs in the battery pack, the fire does not spread to the vehicle, and the vehicle and driver can be safely protected from the effects of the fire.

[0177] Although exemplary embodiments of the present disclosure have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the disclosure as disclosed in the accompanying claims.
