Description

Technical area

[0001] The present disclosure relates to a battery mounting device and a vehicle. State of the art

[0002] Electric vehicles equipped with batteries (e.g., electric cars and electric scooters) are known from the state of the art.

[0003] In recent years, electric vehicles have increasingly adopted battery swapping systems. These systems generally operate on the concept that when the stored energy of the vehicle's battery is depleted, the battery is exchanged at a battery swapping station for another, fully charged battery, instead of recharging the battery each time (see, for example, PTL 1). Citation list for patent literature

[0004] Japanese patent application no. 2023-134543 Summary of the invention: Technical problem

[0005] This type of battery replacement system requires the operation of a locking mechanism (see e.g. Fig. , which will be described later), which holds and secures the battery to the vehicle frame, typically controlled by the control unit, and the battery is removed from the vehicle frame and / or attached to the vehicle frame.

[0006] At this point, the control unit establishes communication with the station system on the side of the battery exchange station and then carries out the replacement of the battery installed in the vehicle in cooperation with the battery changer of the battery exchange station.

[0007] For this reason, this type of locking mechanism is typically equipped with a sensor to ensure safety during battery replacement. The control unit performs the battery change after the sensor detects that the battery release process is complete. This is because the vehicle or the battery could be damaged if the battery replacement machine at the battery replacement station were to operate as usual and forcibly remove the partially locked battery from the vehicle, even if a fault (e.g., a malfunction) occurred in the locking mechanism during the release process.

[0008] In the prior art, this type of battery exchange system typically detects the locking state of the locking mechanism using only one sensor. However, if the system is equipped with only one sensor and the control unit determines from the sensor signal that the switch is ON = locked and the switch is OFF = unlocked, it may register the unlocking even though the lock is not correctly released if the locking mechanism stops during operation due to a malfunction or similar event. Such an incorrect determination can lead to a dangerous situation as described above.

[0009] The present disclosure was made in consideration of the above problems, and one of its aims is to provide a battery mounting device and a vehicle that can accurately determine the mounting status of a battery. Solution to the problem

[0010] To solve the problems described above, a battery fastening device according to the present invention comprises a first locking mechanism and a second locking mechanism, arranged at a first mounting position and a second mounting position of a battery holder in which a battery is stored, and configured to operate in concert to secure the battery to the battery holder. The first locking mechanism includes a first sensor configured to detect operation of the first locking mechanism and to determine whether the battery has been fully locked based on the operating state of the first locking mechanism.The second locking mechanism includes a second sensor configured to detect operation of the second locking mechanism and to recognize battery unlock completion based on the operating state of the second locking mechanism. Advantageous effects of the invention

Description of the embodiments

[0012] Preferred embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. In this description and the drawings, components with substantially the same functions are designated with the same reference numbers, and redundant descriptions are omitted.

[0013] It should be noted that each illustration shows a common orthogonal coordinate system (X, Y, Z) to clarify the positional relationship of each configuration. The positive direction of the Z-axis represents the vertical 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.

[0014] The following describes an exemplary configuration of a battery mounting device (hereinafter referred to as "battery mounting device 1") according to an embodiment of the present invention.

[0015] Fig. Figure 1 is a diagram showing an example of a fixed position of the battery mounting device 1. Fig. is a diagram that shows an example of an overall configuration of the battery mounting device 1.

[0016] The battery mounting device 1 is attached to a vehicle C, such as an electric vehicle or a hybrid vehicle, and holds a battery that serves as a drive energy source for the vehicle C. It should be noted that in Fig. A large vehicle C, such as a truck, is described as a suitable application example for the battery mounting device 1.

[0017] The battery mounting device 1 secures the battery E to the vehicle frame Cf of vehicle C and allows the battery E to be removed from the vehicle frame Cf of vehicle C when necessary, for example. The battery mounting device 1 is attached, for example, to a side surface of the vehicle frame Cf. The vehicle frame Cf (e.g., a steel frame material with a U-shaped cross-section) of vehicle C extends along the longitudinal direction of vehicle C on both the left and right sides of vehicle C and supports the vehicle body and various on-board equipment.

[0018] Battery E is a high-voltage battery that supplies the operating energy for powering vehicle C. For example, a 200-volt class lithium-ion battery is used as battery E.

[0019] It should be noted that Fig. Figure 1 shows two battery mounting devices 1, each holding two batteries E, which are attached to the vehicle frame Cf. The following description assumes that both battery mounting devices 1 have the same configuration, and therefore only the configuration of the battery mounting device 1 that is mounted on the negative side Y (i.e., the left side surface of the vehicle C) is described.

[0020] The battery mounting device 1 comprises, for example, a mounting table 10 on which the battery E is mounted, a sliding rail base 20 which slidably supports the mounting table 10, locking mechanisms 30X and 30Y which secure the battery E to the vehicle frame Cf, and a control unit 100.

[0021] The sliding rail base 20 is, for example, attached to the outer side surface (here the right side surface) of the vehicle frame Cf and extends horizontally from the vehicle frame Cf to the outside of the vehicle C (i.e., in the minus-Y direction). The sliding rail base 20 then guides the assembly table 10 slidably between the battery storage position and the battery installation / removal position in the vehicle C.

[0022] The mounting table 10 is a base on which the battery E is mounted and which is arranged, for example, between two guide elements of the slide rail base 20. It should be noted that the mounting table 10 can only be moved in the ±Y direction along the slide rail base 20.

[0023] Fig. shows a state in which the assembly table 10 is moved from the position for attaching / removing the battery to the position for storing the battery.

[0024] In the battery mounting device 1 according to the present embodiment, when installing the battery E in the vehicle C, the battery E is placed on the mounting table 10 when the mounting table 10 is in the battery mounting / removal position. The battery E, resting on the mounting table 10, is then slid onto the slide rail base 20 and moved from the battery mounting / removal position to the battery storage position. The battery E is then locked in the battery storage position to the vehicle frame Cf by means of the locking mechanisms 30X and 30Y. At this point, the storage of the battery E in the vehicle C is complete if the terminal section Ec of the battery E is connected to a plug in the vehicle C.

[0025] On the other hand, when removing battery E from vehicle C, the locking mechanisms 30X and 30Y in the battery mounting device 1 are actuated according to the present embodiment to release the locked state of battery E on the vehicle frame Cf. Then, battery E, placed on the mounting table 10, is moved on the slide rail base 20 and guided from the battery storage position in vehicle C to the battery mounting / removal position. Then, battery E is lifted at the battery mounting / removal position by a battery changer at a battery exchange station and, for example, removed from vehicle C.

[0026] It should be noted that an example of the operation of the battery exchanger in the battery exchange station can be found, for example, in PTL 1 of the applicant's earlier application.

[0027] Next, a special configuration of the locking mechanisms 30X and 30Y will be described.

[0028] Fig. These are diagrams (top views) showing an example of a configuration of the locking mechanisms 30X and 30Y. Fig. indicates an unlocked state, Fig. shows a transition state between a locked state and an unlocked state and Fig. indicates an unlocked state. Note that in the Fig. Only the battery holder Ea attached to the side of the battery E is shown, and the illustration of the battery E has been omitted.

[0029] Fig. is a diagram showing an example of a battery E configuration. Fig. is a diagram showing an example of a configuration of the locking switch 30cX and the unlocking switch 30cY in the locking mechanisms 30X and 30Y. Fig. is a diagram showing an example of the configuration of a drive section of the locking mechanisms 30X and 30Y.

[0030] The battery mounting device 1 comprises two locking mechanisms 30X and 30Y for securing the battery E to the vehicle frame Cf. The two locking mechanisms 30X and 30Y are arranged at a first mounting position and a second mounting position of a battery holder in which the battery E is accommodated along the longitudinal direction of the vehicle frame Cf, and are attached to the vehicle frame Cf by means of a bracket or the like (hereinafter referred to as "the first mounting position"). The two locking mechanisms 30X and 30Y then secure the battery E to the vehicle frame Cf at the first mounting position and the second mounting position, respectively. Hereinafter, the two locking mechanisms 30X and 30Y are referred to as the "first locking mechanism 30X" and the "second locking mechanism 30Y," respectively.

[0031] The first locking mechanism 30X engages the first latch EbX, which is attached to the side of the battery E, thereby securing the battery E to the vehicle frame Cf in the first mounting position. The second locking mechanism 30Y engages the second latch EbY, which is attached to the side of the battery E, thus securing the battery E to the vehicle frame Cf in the second mounting position. As shown in Fig. As shown, the first latch EbX and the second latch EbY are, for example, rod-shaped elements that are attached to the side surface of the battery E with the battery holder Ea, such that the first latch EbX and the second latch EbY extend in the ±Z direction to positions that protrude from the side surface of the battery E.

[0032] The first and second locking mechanisms 30X and 30Y, for example, consist of a pair of latches 30aX and 30aY paired along the longitudinal direction (±X direction) of the vehicle frame Cf. The first and second locking mechanisms 30X and 30Y are then actuated, for example, by an in-vehicle actuator 31 (here a hydraulic cylinder) to work together. Hereinafter, the latch 30aX of the first locking mechanism 30X is referred to as the "first latch 30aX" and the latch 30aY of the second locking mechanism 30Y is referred to as the "second latch 30aY".

[0033] When battery E is installed in vehicle C, the first and second locking mechanisms 30X and 30Y maintain a locked position in which battery E is secured to the vehicle frame Cf. When you replace battery E, the first and second locking mechanisms 30X and 30Y release the locked position between battery E and vehicle frame Cf.

[0034] The first and second locking bars 30aX and 30aY are hook elements that are rotatably mounted about the Z-axis relative to the vehicle frame Cf and are engaged by the first and second detents EbX and EbY. The first and second locking bars 30aX and 30aY each rotate about the Z-axis in conjunction with the operation of the vehicle's internal actuator 31 (here a hydraulic cylinder). It should be noted that the Fig. Other views show the configuration and operating state of the second bar 30aY from the side opposite the present drawing (i.e., from the side with the minus-Z direction), but the configuration and operating state of the first bar 30aX are the same as the configuration and operating state of bar 30aY.

[0035] When locking battery E to vehicle frame Cf, the first locking bar 30aX rotates counterclockwise around the Z-axis to engage the first detent EbX on the side of battery E and secure the battery to vehicle frame Cf. When locking battery E to vehicle frame Cf, the second locking bar 30aY rotates counterclockwise around the Z-axis to engage the second detent EbY on the side of battery E and secure the battery to vehicle frame Cf. Note that when the first locking bar 30aX and the second locking bar 30aY engage the first and second detent EbX and EbY on the side of battery E to secure the battery to vehicle frame Cf, they pull the battery E towards the side of the vehicle frame Cf (plus the Y direction) (see Fig. ). In this way, the battery E is attached to the vehicle frame Cf without rattling, with the battery holder Ea being pressed against the rubber element 30e, which serves as a stopper on the side of the vehicle frame Cf.

[0036] When you unlock the battery E from the vehicle frame Cf, the first and second latches 30aX and 30aY rotate clockwise around the Z-axis, releasing contact with the first and second detents EbX and EbY respectively on the side of the battery E and allowing the battery E to be removed from the vehicle frame Cf (see Fig. ).

[0037] It should be noted that in the present embodiment, as in the Fig. As shown, the second locking bar 30aY is directly connected to the vehicle's own actuator 31, and the first locking bar 30aX is connected to the vehicle's own actuator 31 via the connecting rod 30b. Thus, the first locking bar 30aX and the second locking bar 30aY are configured to work together.

[0038] The vehicle's internal actuator 31 is, for example, a hydraulic cylinder. At the time of locking and unlocking, the vehicle's internal actuator 31 actuates the piston in the ±X direction to move the connecting rod 30b in the ±X direction. More precisely, when locking, the vehicle's internal actuator 31 actuates the piston so that it extends in the +X direction, and when unlocking, so that it returns to its initial position. Thus, when locking, the first and second latches 30aX and 30aY rotate counterclockwise around the Z-axis, and when unlocking, they engage in the first and second detents EbX and EbY, respectively, on the battery side E. Furthermore, when unlocked, the first and second latches 30aX and 30aY rotate clockwise around the Z-axis and release the contact with the first and second latches EbX and EbY on the battery side E.

[0039] As in Fig. As shown, the vehicle's internal actuator 31 is configured to be driven by a hydraulic circuit 32 connected to the vehicle's internal actuator 31, a drive pump 34 that supplies the hydraulic circuit 32 with operating oil, and a control valve 33, which is located, for example, within the hydraulic circuit 32. This means that the drive pump 34 delivers the operating oil under high pressure to the hydraulic circuit 32, and the control valve 33 regulates the supply of operating oil to the vehicle's internal actuator 31. The vehicle's internal actuator 31 (hydraulic cylinder) thus actuates the piston by converting the fluid energy of the hydraulic oil into mechanical energy.

[0040] It should be noted that the operating state of the vehicle's internal actuator 31 is controlled by the control unit 100. The control unit 100 is, for example, a microcontroller with a central processing unit (CPU), a read-only memory (ROM), a working memory (RAM), an input port, an output port, a communication module, and the like. The control unit 100 controls the opening and closing states of the first relay 102 and the second relay 103, thereby controlling the supply of operating current to the drive pump 34 and the control valve 33 from the auxiliary battery B (a low-voltage battery that supplies operating current to an electrical component mounted in the vehicle C), and, for example, controls the operation of the drive pump 34 and the control valve 33. It should be noted that the control unit 100 corresponds to the "control section" of the present invention.

[0041] The battery mounting device 1 according to the present embodiment is characterized in particular by the fact that it has a status monitoring function by means of the locking switch 30cX and the unlocking switch 30cY in order to ensure safety during battery replacement (see Fig. ).

[0042] The locking switch 30cX, which is located in the first locking mechanism 30X, detects the operation of the first locking mechanism 30X and recognizes the completion of the locking of the battery E based on the operating state of the first locking mechanism 30X.

[0043] The unlocking switch 30cY, which is located in the second locking mechanism 30Y, detects the operation of the second locking mechanism 30Y and recognizes the completion of the unlocking of the battery E based on the operating state of the second locking mechanism 30Y.

[0044] Here, the locking switch 30cX and the unlocking switch 30cY are formed, for example, by a contact switch (see Fig. The contact switch contains, for example, a push button BS and detects when the push button BS is actuated from the outside. Such a contact switch is activated, for example, when the push button BS is pressed inwards by a certain amount from its reference position.

[0045] In the contact-type switch according to the present embodiment, the stroke range of the push button part BS is set to 11 mm and the activation range of the push button part BS is set to 9 mm. That is, the contact switch according to the present embodiment is activated when the push button BS is pressed in 2 mm or more from the reference position (starting position), and it is deactivated when the depression depth is less than 2 mm. The locking switch 30cX and the unlocking switch 30cY each send an activation signal to the control unit 100 when they are activated.

[0046] In the present embodiment, the first locking mechanism 30X comprises a first holder 30dX, which presses the locking switch 30cX when the locking is completed by the operation of the first locking mechanism 30X. Specifically, the first holder 30dX is attached to the first end face of the connecting rod 30b (i.e., at the position of the connecting part on the side of the negative X direction of the connecting rod 30b). The position of the connecting part of the connecting rod 30b on the negative X side is a position that serves as the starting point for the operation of the first locking mechanism 30X, and the first holder 30dX operates in conjunction with the operation of the first locking mechanism 30X and the pivoting movement of the connecting rod 30b.

[0047] It should be noted that in the present embodiment, the first holder 30dX extends from the first end face of the connecting rod 30b in the positive Y direction, and a push button contact part is formed at the end section in the positive Y direction. Furthermore, the locking switch 30cX is arranged such that the push button BS points in the negative Y direction. The first holder 30dX, in conjunction with the pivoting movement of the connecting rod 30b, traces an arc, and after the locking of the first locking mechanism 30X is complete, the push button contact part at the end section presses on the push button part BS of the locking switch 30cX in the positive Y direction (see Figure 3). Fig. ).

[0048] Furthermore, the second locking mechanism 30 includes a second holder 30dY, which presses the release switch 30cY in response to the completion of the release, operating in conjunction with the operation of the second locking mechanism 30Y. Specifically, the second holder 30dY is attached to the second end of the connecting rod 30b (i.e., at the position of the connecting part on the plus-X direction side of the connecting rod 30b) and operates in conjunction with the pivoting movement of the connecting rod 30b. The position of the connecting part of the connecting rod 30b on the plus-X side is a position that serves as the starting point for the operation of the second locking mechanism 30Y, and the second holder 30dY operates in conjunction with the operation of the second locking mechanism 30Y together with the pivoting movement of the connecting rod 30b.

[0049] It should be noted that in the present embodiment, the second holder 30dY extends from the second end of the connecting rod 30b in the positive Y direction, and a push-button contact part is formed on the end section in the positive Y direction. Furthermore, the release switch 30cY with the push-button part BS is arranged in the negative X direction. The second holder 30dY traces an arc in conjunction with the pivoting movement of the connecting rod 30b, and after completion of the release of the second locking mechanism 30Y, the push-button contact part on the end section in the positive Y direction presses the push-button part BS of the release switch 30cY (see Fig. ).

[0050] Here, the operating states of the first and second locking mechanisms 30X and 30Y are determined, for example, by the control unit 100. That is, the control unit 100 detects the sensor signals (i.e., activation signals) of the locking switch 30cX and the unlocking switch 30cY and, based on these sensor signals, determines which of the three states—namely, the locked state, the transition state between locking and unlocking, and the unlocking state—is the current state.

[0051] Here, the control unit 100 generates an error signal regarding the operation of the first and second locking mechanisms 30X and 30Y in a case where the operation of the first and second locking mechanisms 30X and 30Y is complete (i.e., the operation of the vehicle's internal actuator 31 is complete), but the sensor signals of the locking switch 30cX and the unlocking switch 30cY each indicate that the first and second locking mechanisms 30X and 30Y are in a "transitional state".

[0052] The control unit 100 then sends the fault signal to the system on the battery exchange station side. If the system on the battery exchange station side receives a fault signal, it stops the battery exchange machine from operating. This prevents the battery exchange station from operating as usual to forcibly remove the partially locked battery from the vehicle, even though there is a fault in the first and second locking mechanisms 30X and 30Y.

[0053] The following is an example of the workflow of the control unit 100.

[0054] Fig. These are diagrams that show an example of an operating sequence of control unit 100. The diagrams in Fig. The flowcharts shown illustrate processes that are repeatedly executed by control unit 100 at predetermined intervals (e.g. every 100 msec) in accordance with a computer program.

[0055] In step S1, the control unit 100 determines whether the locking switch 30cX is in the ON state. If the locking switch 30cX is in the ON state (S1: YES), the control unit 100 proceeds to step S3, and if the locking switch 30cX is NOT in the ON state (S1: NO), the control unit 100 proceeds to step S2.

[0056] In step S2, control unit 100 determines whether the unlocking switch 30cY is in the ON state. If the unlocking switch 30cY is in the ON state (S2: YES), control unit 100 proceeds to step S4, and if the unlocking switch 30cY is NOT in the ON state (S2: NO), control unit 100 proceeds to step S5.

[0057] In step S3, the control unit 100 determines that the mounting status of battery E is in a state where the locking mechanism is complete.

[0058] In step S4, the control unit 100 determines that the mounting state of battery E is the unlocked state.

[0059] In step S5, the control unit 100 determines that the mounting state of battery E is a transitional state between the locked and unlocked states. In this case, there is a possibility that a fault has occurred in the first and second locking mechanisms 30X and 30Y, and therefore the control unit 100 performs the processing in the subsequent step S6.

[0060] In step S6, control unit 100 executes the following: Fig. The error detection processing described above is carried out.

[0061] In step S61, the control unit 100 determines whether the operation of the vehicle's internal actuator 31 is complete. If the operation of the vehicle's internal actuator 31 is complete (S61: YES), the control unit 100 proceeds to step S62, and if the operation of the vehicle's internal actuator 31 is not complete (S61: NO), the process is stopped in the flowchart of Fig. It ends without any specific processing being carried out.

[0062] In step S62, control unit 100 detects a fault in the first and second locking mechanisms 30X and 30Y and generates a fault signal. Control unit 100 sends this fault signal to a system on the battery exchange station side.

[0063] In this way, the control unit 100 sequentially acquires the sensor signals from the locking switch 30cX and the unlocking switch 30cY to monitor the charging status of battery E (i.e., the operating status of the first and second locking mechanisms 30X and 30Y). This enables the control unit 100 to detect a situation in which a fault has occurred in the first and second locking mechanisms 30X and 30Y. Effects

[0064] As described above, the battery mounting device 1 according to the present embodiment comprises: the first locking mechanism and the second locking mechanism, which are arranged at the first and second mounting positions of the battery holder (vehicle frame Cf in the embodiment described above), into which the battery is inserted, in order to work together and secure the battery to the battery holder. The first locking mechanism comprises the first sensor (locking switch 30cX in the embodiment described above), which detects the operation of the first locking mechanism and recognizes the completion of the battery locking based on the operating state of the first locking mechanism.The second locking mechanism includes the second sensor (unlock switch 30cY in the embodiment described above) which detects the operation of the second locking mechanism and recognizes the unlocking of the battery based on the operating state of the second locking mechanism.

[0065] Thus, with the battery fastening device 1 of the present embodiment, it is possible to accurately determine the fastening status of the battery E and to accurately detect the occurrence of a fault condition in the first and second locking mechanism 30X and 30Y.

[0066] For example, even in a case where a malfunction occurs in the first and second locking mechanisms 30X and 30Y during unlocking (e.g., in a case where the vehicle's internal actuator 31 stops halfway), it is possible to prevent the battery replacement machine from forcibly pulling out the half-locked latch.

[0067] The present invention is not limited to the embodiments described above and can be applied to various modifications.

[0068] In the embodiment described above, for example, an example of a battery mounting device 1 has been described in which the battery E is displaceable between the battery storage position and the battery mounting / removal position on the slide rail base 20, but the configuration for supporting the battery E is not limited in the present invention.

[0069] Furthermore, in the embodiment described above, a pair of latches 30aX and 30aY is described as an example of the locking mechanisms 30X and 30Y. However, the locking mechanisms 30X and 30Y used in the present invention are optional, and other locking mechanisms can also be used.

[0070] Although the specific examples of the present invention have been described in detail above, these specific examples are merely examples and do not limit the scope of the claims. The technology described in the claims comprises various modifications and variations of the specific examples presented above.
