Description

[Technical Field]

[0001] The present disclosure relates to a battery mounting device and a vehicle. [Background technology]

[0002] BACKGROUND ART Electric vehicles equipped with batteries (for example, electric cars and electric scooters) have been known in the past.

[0003] In recent years, battery exchange systems have been increasingly adopted in this type of electric vehicle. These battery exchange systems are generally designed based on the concept that when the stored power of a battery installed in a vehicle becomes low, the battery is exchanged with another fully charged battery at a battery exchange station, instead of charging the battery each time (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent application No. 2023-134543 Summary of the Invention [Problem to be solved by the invention]

[0005] In this type of battery exchange system, the operation of a locking mechanism (see, for example, Figures 3, 4, and 5 described below) that supports and secures the battery to the vehicle frame is typically controlled by the ECU, and the battery is removed from and / or attached to the vehicle frame.

[0006] At this time, the ECU establishes communication with the station system at the battery exchange station, and then works with the battery exchange machine at the battery exchange station to exchange the battery installed in the vehicle.

[0007] For this reason, this type of locking mechanism is usually equipped with a sensor to ensure safety during battery replacement, and the ECU performs the battery replacement only after detecting that the battery has been unlocked by the sensor. This is because if a malfunction (i.e., a defect) occurs in the locking mechanism during unlocking, and the battery replacement machine at the battery replacement station continues to operate and tries to forcibly remove the half-locked battery from the vehicle, this could result in damage to the vehicle and / or battery.

[0008] However, in the past, most battery exchange systems of this type have used only one sensor to detect the locked state of the locking mechanism. However, if only one sensor is provided and the ECU determines that switch ON = locked and switch OFF = unlocked based on the sensor signal, if the locking mechanism stops midway due to a malfunction or other reason, However, the system may mistakenly determine that the lock is unlocked even though it is not properly unlocked. If such a mistaken determination is made, the dangerous situation described above may occur.

[0009] The present disclosure has been made in consideration of the above-mentioned problems, and aims to provide a battery mounting device and a vehicle that make it possible to accurately determine the retention state of a battery. [Means for solving the problem]

[0010] The main invention that solves the above-mentioned problems is: a first locking mechanism and a second locking mechanism which are disposed at first and second mounting positions of a storage section in which a battery is stored and which operate in conjunction with each other to fix the battery to the storage section; the first locking mechanism is provided with a first sensor that senses operation of the first locking mechanism and detects completion of locking of the battery based on the operating state of the first locking mechanism; The second locking mechanism is provided with a second sensor that senses the operation of the second locking mechanism and detects the completion of unlocking of the battery based on the operating state of the second locking mechanism. A battery mounting device. [Effects of the Invention]

[0013] Preferred embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. In this specification and drawings, components having substantially the same functions are designated by the same reference numerals, and redundant description will be omitted.

[0014] In each figure, a common Cartesian coordinate system (X, Y, Z) is shown to clarify the positional relationship of each component. The positive direction of the Z axis represents the vertically upward direction of the vehicle, the positive direction of the X axis represents the forward direction of the vehicle, and the positive direction of the Y axis represents the lateral direction of the vehicle.

[0015] An example of the configuration of a battery mounting device according to one embodiment of the present invention (hereinafter referred to as "battery mounting device 1") will be described below.

[0016] Fig. 1 is a diagram showing an example of an application position of the battery mounting device 1. Fig. 2 is a diagram showing an example of the overall configuration of the battery mounting device 1.

[0017] The battery mounting device 1 is mounted on an electric vehicle C such as an electric car or a hybrid car, and holds a battery used as a driving power source for the vehicle C. Note that FIG. 1 illustrates a large vehicle C such as a truck as an example of a suitable application of the battery mounting device 1.

[0018] The battery mounting device 1, for example, holds the battery E fixed to the vehicle frame Cf of the vehicle C, and allows the battery E to be attached to and detached from the vehicle frame Cf of the vehicle C as needed. The battery mounting device 1 is attached to, for example, a side surface of the vehicle frame Cf. Note that the vehicle frame Cf of the vehicle C (for example, a steel frame with a U-shaped cross section) The aggregates extend along the longitudinal direction of the vehicle C, are arranged on both the left and right sides of the vehicle C, and support the vehicle body and various on-board equipment.

[0019] The battery E is a high-voltage battery that supplies operating power for driving the vehicle C. As the battery E, for example, a 200V-class lithium ion battery is used.

[0020] 1 shows two batteries E attached to the vehicle frame Cf and two battery mounting devices 1 that separately hold the two batteries E. In the following, the two battery mounting devices 1 are assumed to have the same configuration, for example, and only the configuration of the battery mounting device 1 mounted on the negative Y side (i.e., the left side of the vehicle C) will be described.

[0021] The battery mounting device 1 includes, for example, a mounting base 10 on which the battery E is placed, a slide rail base 20 that supports the mounting base 10 so that it can slide, locking mechanisms 30X and 30Y that attach the battery E to the vehicle frame Cf, and an ECU 100.

[0022] The slide rail base 20 is attached, for example, to the outer side surface (here, the right side surface) of the vehicle frame Cf and extends horizontally from the vehicle frame Cf toward the outside (i.e., the negative Y direction side) of the vehicle C. The slide rail base 20 guides the mounting base 10 so that it can slide between a battery storage position and a battery attachment / detachment position within the vehicle C.

[0023] The mounting table 10 is a base on which the battery E is placed, and is disposed, for example, so as to span between two guide members of the slide rail base 20. The mounting table 10 is slidable along the slide rail base 20 only in the ±Y directions.

[0024] FIG. 2 shows a state in which the mounting table 10 has been slid from the state in which it is pulled out to the battery attachment / detachment position to the battery storage position.

[0025] In the battery mounting device 1 according to this embodiment, when the battery E is stored in the vehicle C, the battery E is placed on the mounting base 10 when the mounting base 10 is in the battery attachment / detachment position. Then, while the battery E is placed on the mounting base 10, the battery E is slid along the slide rail base 20 and guided from the battery attachment / detachment position to the battery storage position. Then, at the battery storage position, the battery E is locked to the vehicle frame Cf using the locking mechanisms 30X and 30Y. At this time, the terminal portion Ec of the battery E is connected to a connector in the vehicle C, thereby completing the storage of the battery E in the vehicle C.

[0026] On the other hand, in the battery mounting device 1 according to this embodiment, when the battery E is removed from inside the vehicle C, for example, the locking mechanisms 30X and 30Y are driven to release the battery E from the locked state to the vehicle frame Cf. Then, while the battery E is placed on the mounting base 10, it is slid along the slide rail base 20 and guided from the battery storage position inside the vehicle C to the battery attachment / detachment position. Then, at the battery attachment / detachment position, the battery E is pulled up, for example, to a battery exchange machine at a battery exchange station and removed from the vehicle C.

[0027] For an example of the operation of the battery exchange machine in the battery exchange station, please refer to, for example, Patent Document 1, a prior application of the applicant of the present application.

[0028] Next, the detailed configuration of the locking mechanisms 30X and 30Y will be described in detail.

[0029] 3, 4, and 5 are diagrams (plan views) showing an example of the configuration of the locking mechanisms 30X and 30Y. FIG. 3 shows the unlocked state, and FIG. 4 shows the transition between the locked state and the unlocked state. 3, 4, and 5, the battery E is not shown, and only the battery bracket Ea attached to the side of the battery E is shown.

[0030] Fig. 6 is a diagram showing an example of the configuration of battery E. Fig. 7 is a diagram showing an example of the configuration of lock switch 30cX and unlock switch 30cY provided in lock mechanisms 30X and 30Y. Fig. 8 is a diagram showing an example of the configuration of a drive unit for lock mechanisms 30X and 30Y.

[0031] The battery mounting device 1 has two locking mechanisms 30X and 30Y for mounting the battery E to the vehicle frame Cf. The two locking mechanisms 30X and 30Y are disposed at a first mounting position and a second mounting position of a storage section in which the battery E is stored along the front-rear direction of the vehicle frame Cf, and are fixed to the vehicle frame Cf via a bracket or the like (omitted below). The two locking mechanisms 30X and 30Y fix the battery E to the vehicle frame Cf at the first mounting position and the second mounting position, respectively. Note that hereinafter, the two locking mechanisms 30X and 30Y are also referred to as the "first locking mechanism 30X" and the "second locking mechanism 30Y," respectively.

[0032] The first locking mechanism 30X secures the battery E to the vehicle frame Cf at a first attachment position by engaging with a first striker EbX attached to the side of the battery E. The second locking mechanism 30Y secures the battery E to the vehicle frame Cf at a second attachment position by engaging with a second striker EbY attached to the side of the battery E. Here, as shown in FIG. 6, the first striker EbX and the second striker EbY are, for example, rod-shaped members, and are each attached to the side of the battery E by a battery bracket Ea so as to extend in the ±Z directions to positions protruding from the side of the battery E.

[0033] The first and second locking mechanisms 30X, 30Y are configured, for example, by a pair of latches 30aX, 30aY that are provided in pairs along the fore-and-aft direction (±X direction) of the vehicle frame Cf. The first and second locking mechanisms 30X, 30Y are driven, for example, by an on-vehicle actuator 31 (here, a hydraulic cylinder) and operate in conjunction with each other. Note that, hereinafter, the latch 30aX of the first locking mechanism 30X will be referred to as the "first latch 30aX," and the latch 30aY of the second locking mechanism 30Y will be referred to as the "second latch 30aY."

[0034] The first and second locking mechanisms 30X, 30Y maintain a locked state in which the battery E is fixed to the vehicle frame Cf when the battery E is stored inside the vehicle C. Furthermore, the first and second locking mechanisms 30X, 30Y release the locked state between the battery E and the vehicle frame Cf when the battery E is replaced.

[0035] The first and second latches 30aX and 30aY are hook members that are supported on the vehicle frame Cf to be rotatable around the Z axis and engage with the first and second strikers EbX and EbY. The first and second latches 30aX and 30aY each rotate around the Z axis in conjunction with the operation of an on-vehicle actuator 31 (here, a hydraulic cylinder). Note that FIGS. 3, 4, and 5 show separate views of the configuration and operating state of the second latch 30aY viewed from the opposite side of the drawings (i.e., from the minus Z direction), but the configuration and operating state of the first latch 30aX are similar to those of the latch 30aY.

[0036] When locking the battery E to the vehicle frame Cf, the first latch 30aX rotates counterclockwise around the Z axis and engages with the first striker EbX on the battery E side, fixing the battery E to the vehicle frame Cf. When locking the battery E to the vehicle frame Cf, the second latch 30aY rotates counterclockwise around the Z axis and engages with the second striker EbY on the battery E side, fixing the battery E to the vehicle frame Cf. The battery bracket EaY engages with the first and second strikers EbX, EbY on the battery E side and operates to pull the battery E toward the vehicle frame Cf (in the positive Y direction) when fixing the battery E to the vehicle frame Cf (see FIG. 5). As a result, the battery bracket Ea is pressed against the rubber member 30e fixed to the vehicle frame Cf side as a stopper, and the battery E is fixed to the vehicle frame Cf without rattle.

[0037] Furthermore, when unlocking the battery E from the vehicle frame Cf, the first and second latches 30aX and 30aY rotate clockwise around the Z axis, disengaging from the first and second strikers EbX and EbY on the battery E side, thereby enabling the battery E to be removed from the vehicle frame Cf (see Figure 3).

[0038] 3, 4, and 5, in this embodiment, the second latch 30aY is directly connected to the on-vehicle actuator 31, and the first latch 30aX is connected to the on-vehicle actuator 31 via the link rod 30b. As a result, the first latch 30aX and the second latch 30aY are configured to operate in conjunction with each other.

[0039] The on-vehicle actuator 31 is, for example, a hydraulic cylinder that operates a piston along the ±X directions when locking and unlocking, causing the link rod 30b connected to the on-vehicle actuator 31 to swing along the ±X directions. Specifically, the on-vehicle actuator 31 protrudes the piston along the +X direction when locking, and operates to return the piston to its initial state when unlocking. As a result, the first and second latches 30aX and 30aY rotate counterclockwise around the Z axis when locked and engage with the first and second strikers EbX and EbY on the battery E side. Furthermore, the first and second latches 30aX and 30aY rotate clockwise around the Z axis when unlocking, releasing their engagement with the first and second strikers EbX and EbY on the battery E side.

[0040] 8, the on-vehicle actuator 31 is configured to be driven by a hydraulic circuit 32 connected to the on-vehicle actuator 31, a drive pump 34 that supplies hydraulic oil to the hydraulic circuit 32, and a control valve 33 arranged in the hydraulic circuit 32. That is, the drive pump 34 sends high-pressure hydraulic oil to the hydraulic circuit 32, and the control valve 33 controls the supply state of the hydraulic oil to the on-vehicle actuator 31. As a result, the on-vehicle actuator 31 (hydraulic cylinder) converts the fluid energy of the hydraulic oil into mechanical energy to operate the piston.

[0041] The operating state of the on-vehicle actuator 31 is controlled by the ECU 100. The ECU 100 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), an input port, an output port, and a communication module. The ECU 100 is a microcomputer configured to include the above components. For example, by controlling the open / close states of a first relay 102 and a second relay 103, the ECU 100 controls the supply of operating power from an auxiliary battery B (a low-voltage battery that supplies operating power to on-board electrical components mounted on a vehicle C) to the drive pump 34 and the control valve 33, and controls the operation of the drive pump 34 and the control valve 33. The ECU 100 corresponds to the "control unit" of the present invention.

[0042] The battery mounting device 1 according to this embodiment is characterized in that it has a status monitoring function using a lock switch 30cX and an unlock switch 30cY to ensure safety during battery replacement (see Figures 3 to 5).

[0043] The lock switch 30cX is disposed in the first lock mechanism 30X, senses the operation of the first lock mechanism 30X, and detects whether the battery E has been locked based on the operating state of the first lock mechanism 30X.

[0044] The unlock switch 30cY is disposed in the second lock mechanism 30Y, senses the operation of the second lock mechanism 30Y, and detects the completion of unlocking of the battery E based on the operating state of the second lock mechanism 30Y.

[0045] Here, the lock switch 30cX and the unlock switch 30cY are each configured, for example, as a contact switch (see FIG. 7). The contact switch has, for example, a push button portion BS and detects an external pressing action on the push button portion BS. Such a contact switch turns on, for example, when the push button portion BS is pressed a predetermined amount from a reference position.

[0046] In the contact switch according to this embodiment, the stroke range of the push button BS is set to 11 mm, and the switch-on range of the push button BS is set to 9 mm. That is, the contact switch according to this embodiment switches on when the push button BS is pressed 2 mm or more from the reference position (initial position), and switches off when the pressing amount is less than 2 mm. When switched on, the lock switch 30cX and the unlock switch 30cY each send a switch-on signal to the ECU 100.

[0047] In this embodiment, the first locking mechanism 30X includes a first bracket 30dX that operates in conjunction with the operation of the first locking mechanism 30X to press the lock switch 30cX when locking is completed. Specifically, the first bracket 30dX is fixed to the first end side of the link rod 30b (i.e., the position of the link portion on the minus X direction side of the link rod 30b). The position of the link portion on the minus X direction side of the link rod 30b is the position that serves as the operation starting point of the first locking mechanism 30X, and the first bracket 30dX operates in conjunction with the operation of the first locking mechanism 30X in conjunction with the swinging movement of the link rod 30b.

[0048] In this embodiment, the first bracket 30dX extends in the positive Y direction from the first end of the link rod 30b, and has a button contact portion formed at its end in the positive Y direction. The lock switch 30cX is disposed with its push button portion BS facing in the negative Y direction. The first bracket 30dX moves in an arc in conjunction with the swinging motion of the link rod 30b, and when the first lock mechanism 30X completes locking, the button contact portion at its end in the positive Y direction presses the push button portion BS of the lock switch 30cX (see FIG. 5).

[0049] The second locking mechanism 30 also includes a second bracket 30dY that operates in conjunction with the operation of the second locking mechanism 30Y to press the unlock switch 30cY upon completion of unlocking. Specifically, the second bracket 30dY is fixed to the second end side of the link rod 30b (i.e., the position of the link portion on the positive X direction side of the link rod 30b) and operates in conjunction with the swinging motion of the link rod 30b. The position of the link portion on the positive X direction side of the link rod 30b is the position that serves as the operation starting point of the second locking mechanism 30Y, and the second bracket 30dY operates in conjunction with the operation of the second locking mechanism 30Y in conjunction with the swinging motion of the link rod 30b.

[0050] In this embodiment, the second bracket 30dY extends in the positive Y direction from the second end of the link rod 30b, and has a button contact portion formed at its end in the positive Y direction. The unlock switch 30cY is disposed with its push button portion BS facing in the negative X direction. The second bracket 30dY moves in an arc in conjunction with the swinging motion of the link rod 30b, and when the second lock mechanism 30Y completes unlocking, the button contact portion at its end in the positive Y direction presses the push button portion BS of the unlock switch 30cY (see FIG. 3).

[0051] Here, the operating states of the first and second locking mechanisms 30X, 30Y are determined, for example, by the ECU 100. That is, the ECU 100 acquires the sensor signals (i.e., switch ON signals) of the lock switch 30cX and the unlock switch 30cY, and determines which of the three states is in the locking state, the transition state between the locking state and the unlocking state, or the unlocking state based on the sensor signals of the locking switch 30cX and the unlocking switch 30cY.

[0052] Here, the ECU 100 generates a fault occurrence signal relating to the operation of the first and second locking mechanisms 30X, 30Y, for example, when the sensor signals of the lock switch 30cX and the unlock switch 30cY indicate that the first and second locking mechanisms 30X, 30Y are in a "transition state" even though the operation of the first and second locking mechanisms 30X, 30Y has been completed (i.e., the operation of the on-board actuator 31 has been completed).

[0053] The ECU 100 then transmits a failure occurrence signal to the system at the battery exchange station. When the system at the battery exchange station receives the failure occurrence signal, it stops the operation of the battery exchange machine. This prevents the battery exchange machine from continuing to operate despite a malfunction in the first and second locking mechanisms 30X, 30Y, and from forcibly removing the half-locked battery from the vehicle.

[0054] An example of the operation flow of the ECU 100 will be described below.

[0055] 9 and 10 are diagrams showing an example of an operation flow of the ECU 100. The flowcharts shown in Fig. 9 and 10 are processes that the ECU 100 repeatedly executes at predetermined intervals (for example, every 100 msec) according to a computer program.

[0056] In step S1, the ECU 100 determines whether the lock switch 30cX is in the ON state. If the lock switch 30cX is in the ON state (S1: YES), the ECU 100 proceeds to step S3, and if the lock switch 30cX is not in the ON state (S1: NO), the ECU 100 proceeds to step S2.

[0057] In step S2, the ECU 100 determines whether the unlock switch 30cY is in the ON state. If the unlock switch 30cY is in the ON state (S2: YES), the ECU 100 proceeds to step S4, and if the unlock switch 30cY is not in the ON state (S2: NO), the ECU 100 proceeds to step S5.

[0058] In step S3, the ECU 100 determines that the holding state of the battery E is the locked state.

[0059] In step S4, the ECU 100 determines that the holding state of the battery E is the unlocked state.

[0060] In step S5, the ECU 100 determines that the holding state of the battery E is in a transition state between the locked state and the unlocked state. However, in this case, since there is a possibility that a failure has occurred in the first and second locking mechanisms 30X, 30Y, the ECU 100 performs the process of the following step S6.

[0061] In step S6, the ECU 100 performs a failure determination process shown in FIG.

[0062] In step S61, the ECU 100 determines whether the operation of the in-vehicle actuator 31 is complete. If the operation of the in-vehicle actuator 31 is in a completed state (S61: YES), the ECU 100 proceeds to step S62, and if the operation of the in-vehicle actuator 31 is not in a completed state (S61: NO), the ECU 100 ends the processing of the flowchart in FIG. 10 without performing any particular processing.

[0063] In step S62, the ECU 100 determines that a malfunction has occurred in the first and second locking mechanisms 30X and 30Y, and generates a malfunction occurrence signal. The ECU 100 transmits the malfunction occurrence signal to the system on the battery exchange station side.

[0064] In this way, the ECU 100 sequentially acquires the sensor signals of the lock switch 30cX and the unlock switch 30cY and monitors the holding state of the battery E (i.e., the operating states of the first and second locking mechanisms 30X, 30Y). This enables the ECU 100 to detect a malfunction in the first and second locking mechanisms 30X, 30Y.

[0065] [effect] As described above, the battery mounting device 1 according to this embodiment is a first locking mechanism and a second locking mechanism that are disposed at first and second mounting positions of a storage section (in the above embodiment, the vehicle frame Cf) in which the battery is stored and that operate in conjunction with each other to fix the battery to the storage section; The first locking mechanism is provided with a first sensor (in the above embodiment, a lock switch 30cX) that senses the operation of the first locking mechanism and detects that the battery has been locked based on the operating state of the first locking mechanism, The second locking mechanism is provided with a second sensor (unlock switch 30cY in the above embodiment) that senses the operation of the second locking mechanism and detects the completion of unlocking of the battery based on the operating state of the second locking mechanism.

[0066] Therefore, according to the battery mounting device 1 of this embodiment, it is possible to accurately determine the holding state of the battery E, and in addition, it is also possible to accurately detect the occurrence of a failure state in the first and second locking mechanisms 30X, 30Y.

[0067] This makes it possible to stop the battery exchange machine from forcibly pulling out the latch in a half-locked state, for example, even if some kind of malfunction occurs in the first and second locking mechanisms 30X, 30Y while unlocking (for example, if the on-board actuator 31 stops midway).

[0068] The present invention is not limited to the above-described embodiment, but can be applied to various modified aspects.

[0069] For example, in the above embodiment, as an example of the battery mounting device 1, a configuration was shown in which the battery E can be slid between a battery storage position and a battery attachment / detachment position using a slide rail base 20, but in the present invention, the support configuration of the battery E is arbitrary.

[0070] In the above embodiment, the pair of latches 30aX and 30aY are shown as an example of the locking mechanisms 30X and 30Y. However, the locking mechanisms 30X and 30Y used in the present invention are arbitrary, and other locking mechanisms may also be used.

[0071] Although specific examples of the present invention have been described above in detail, these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and alterations of the specific examples exemplified above. [Industrial Applicability]
