Summary of the Invention

Problems to be Solved by the Invention

[0004] In the assembled vehicle disclosed in Patent Document 1 described above, the vehicle is divided into two parts vertically for connection and disconnection, but the case of dividing and connecting / disconnecting each structural member of the vehicle is not disclosed.

[0005] This disclosure has been made in view of such circumstances, and provides a vehicle that can be connected and disconnected separately for each structural member of the vehicle.

Means for Solving the Problems

[0006] The vehicle according to this disclosure is a vehicle composed of a plurality of structural members, coils are wound around at least both ends of the structural member, by changing the current flowing through the coil, the structural members are magnetized so that the structural members can be connected to each other by magnetic force, and the structural members are demagnetized so that the connection state between the structural members can be released, and the two states are switched.

[0007] In the vehicle described herein, the structural members can be reversibly switched between a magnetized state and a demagnetized state. Therefore, the vehicle's structural members are connected and disassembled separately.

[0008] The vehicle related to this disclosure is A vehicle composed of multiple structural members, Coils are wound around at least both ends of the structural member. By applying the coil current, the structural members are magnetized so that they can be connected to each other by magnetic force. By heating the structural members to a temperature above the Curie temperature, the structural members are demagnetized so that the connection between them can be released.

[0009] In the vehicle described herein, the structural members can be reversibly switched between a magnetized state and a demagnetized state. Therefore, the vehicle's structural members are connected and disassembled separately.

[0010] The vehicle related to this disclosure is A vehicle composed of multiple structural members, Coils are wound around at least both ends of the structural member. By applying a direct current to the coil, the structural members are magnetized so that they can be connected to each other by magnetic force. By applying an alternating current to the coil, the structural members are demagnetized so that the connection between them can be released.

[0011] In the vehicle described herein, the structural members can be reversibly switched between a magnetized state and a demagnetized state. Therefore, the vehicle's structural members are connected and disassembled separately.

[0012] Each of the structural members becomes an S pole at one end and an N pole at the other end by passing an electric current through the coil. Among two adjacent structural members, the S pole of one structural member and the N pole of the other structural member are attracted by magnetic force, so that the structural members may be connected in a connected state. With such a configuration, since the S poles and N poles of the structural members are alternately arranged, the structural members can be connected to each other.

[0013] In the connected state, when the amount of the metal pieces attracted to the structural member exceeds a predetermined amount, the electric current flowing through the coil may be reduced. With such a configuration, the metal pieces attracted in the connected state can be reduced, and the generation of rust in the vehicle can be suppressed.

Effect of the Invention

[0014] According to the present disclosure, a vehicle that can be disassembled and connected separately for each structural member of the vehicle can be provided.

Mode for Carrying Out the Invention

[0016] Hereinafter, the present disclosure will be described through embodiments of the invention, but the invention according to the claims is not limited to the following embodiments. Also, not all of the configurations described in the embodiments are essential as means for solving the problems. For the sake of clarity of explanation, the following description and drawings have been appropriately omitted and simplified. In each drawing, the same reference numerals are assigned to the same elements, and duplicate explanations are omitted as necessary.

[0017] Of course, the right-handed xyz orthogonal coordinates shown in the drawings are for convenience in explaining the positional relationship of the components. Usually, the positive direction of the z-axis is vertically upward, and the xy plane is a horizontal plane.

[0018] (Embodiment 1) <Configuration of Vehicle> First, referring to FIG. 1, the configuration of the vehicle according to Embodiment 1 will be described. FIG. 1 is a configuration diagram of the vehicle according to Embodiment 1. As shown in FIG. 1, the vehicle 10 includes an electrical equipment 30 and a structural member 11.

[0019] The vehicle 10 is composed of a plurality of structural members 11. The structural member 11 is, for example, the frame or piping of the vehicle 10. The structural member 11 is, for example, a hollow member. The cross-sectional shape of the structural member 11 is, for example, a quadrangle, polygon, triangle, circle, or U-shaped. Also, the structural member 11 is not limited to a hollow member, and may be a member without a cavity, such as a quadrangular prism or a cylindrical column. Note that the dimensions such as the plate thickness, diameter, and length of the structural member 11 are arbitrary. The structural member 11 is made of a material that magnetizes when a current or voltage is applied and demagnetizes by any one of the termination of the application of the current or voltage, temperature change, application of a current different from the applied current type, or a combination of these.

[0020] The electrical equipment 30 includes a power supply 12, an inverter 13, and a coil 14. In the electrical equipment 30, the inverter 13 controls the current and voltage flowing from the power supply 12 to the coil 14. By applying current and voltage to the coil 14, the structural members 11 are magnetized, and the structural members 11 attract each other by magnetic force. The coil 14 will be described in detail later.

[0021] In the example shown in Figure 1, the electrical equipment 30 is configured to be installed in the vehicle 10, but it is not limited to this configuration and may be installed outside the vehicle 10. When the vehicle 10 is equipped with the electrical equipment 30, the power source 12 is, for example, a lithium-ion battery. In this case, the current from the power source 12 is a direct current. On the other hand, when the electrical equipment 30 is installed outside the vehicle 10, the power source 12 is, for example, a generator. In this case, the current from the power source 12 is an alternating current.

[0022] The inverter 13 is capable of converting alternating current to direct current. Furthermore, the inverter 13 includes a processing unit, such as a CPU (Central Processing Unit), and a storage unit, such as RAM (Random Access Memory) or ROM (Read Only Memory), which stores various control programs and data. In other words, the inverter 13 functions as a computer and performs various processes based on the aforementioned control programs.

[0023] <coil> The coil will be explained with reference to Figure 2. Figure 2 shows a structural member and a coil. As shown in Figure 2, the coil 14 is wound around one end R1 of the structural member 11. Also as shown in Figure 2, the coil 14 is wound around the other end R2 of the structural member 11. In this way, the coil 14 is wound around at least both ends R1 and R2 of the structural member 11. The coil 14 is always wound around the structural member 11. However, it is not limited to this, and the coil 14 may be wound around and removed from the structural member each time the structural member is magnetized and demagnetized, as described later.

[0024] <Magneticization of structural members> Referring to Figure 2, the case of magnetizing a structural member will be explained. At one end R1, when current (or voltage) is applied to the coil 14 from the power supply 12 (see Figure 1), the coil 14 becomes negative and positive from left to right. Similarly, at the other end R2, when current is applied to the coil 14 from the power supply 12 (see Figure 1), the coil 14 becomes positive and negative from left to right. In other words, by applying current to the coil 14, the structural member 11 becomes magnetized and has a function similar to that of a magnet. Note that the direction of the current flowing through the coil 14 near one end R1 and the direction of the current flowing through the coil 14 near the other end R2 are opposite.

[0025] In this way, by applying current to the coil 14, the structural members 11 become magnetized. This allows the structural members 11 to be connected to each other by magnetic force. Therefore, even if the vehicle is transported to the site in separate structural members 11, the structural members 11 can be connected at the site. Details of the connected state will be described later.

[0026] <Demagnetization of structural members> Referring to Figure 2, the case of demagnetizing the structural member 11 will be explained. When the application of current from the power supply 12 (see Figure 1) to the coil 14 is stopped, the magnetic fields at both ends R1 and R2 are lost, and the structural member 11 can be demagnetized. This allows the structural member 11 to be released from its connected state. Therefore, the vehicle can be disassembled into its structural member 11 and transported. Alternatively, by demagnetizing the structural member 11 from a magnetized state, it is possible to maintain the connected state without disassembly.

[0027] In the above, an example was described in which the application of current from the power supply 12 (see Figure 1) to the coil 14 is stopped to demagnetize the structural member 11. However, the method of demagnetization is not limited to this, and may be done as follows.

[0028] The structural member 11 may also be demagnetized by reversing the direction of the current flowing through each coil 14. That is, the current flowing through the coil 14 near one end R1 is reversed, and the current flowing through the coil 14 near the other end R2 is also reversed. This generates a magnetic field that resonates with the magnetic field in the connected state, thus demagnetizing the structural member 11 while attenuating it. In this way, the structural member 11 can be demagnetized by changing the state from one in which current is applied to the coil 14 to one in which the application is stopped, or by reversing the direction of the current flowing through the coil 14. In other words, the structural member 11 can be demagnetized by changing the current flowing through the coil 14.

[0029] Alternatively, the structural member 11 may be demagnetized by heating it to a temperature above the Curie temperature. Furthermore, if the structural member 11 is magnetized by applying a DC current to the coil 14, the structural member 11 may be demagnetized by applying an AC current to the coil 14.

[0030] <Linked state> The connection state between structural members will be explained with reference to Figures 3 and 4. Figures 3 and 4 show an example of the connection state between structural members. In Figures 3 and 4, the explanation assumes that structural members 111 and 112 are magnetized by applying current to the coil. Although the coil is omitted in Figures 3 and 4, it is assumed here that coils are always wound around structural members 111 and 112. Note that the structural members are connected to each other when the vehicle is in motion, for example.

[0031] As shown in Figures 3 and 4, structural members 111 and 112 have ends R1 and R2. As shown in Figures 3 and 4, when current is passed through the coil of structural member 111, one end R1 becomes a south pole 21 and the other end R2 becomes a north pole 20. Similarly, when current is passed through the coil of structural member 112, one end R1 becomes a south pole 21 and the other end R2 becomes a north pole 20. In this way, structural members 111 and 112 have alternating south poles 21 and north poles 20.

[0032] As shown in Figure 3, the south pole 21 of one structural member 111 and the north pole 20 of the other structural member 112 attract each other by magnetic force, resulting in a connected state between the two adjacent structural members 111 and 112.

[0033] In the connected state shown in Figure 3, the end face at end R2 of structural member 111 and the end face at end R1 of structural member 112 are connected by magnetic force. However, the connected state is not limited to the example shown in Figure 3, and as shown in Figure 4, the end R2 of structural member 111 may be fitted and connected to the end R1 of structural member 112.

[0034] Furthermore, since the current (or voltage) from the power supply 12 (see Figure 1) can be adjusted by the inverter 13, the connection (joining) strength of structural members 111 and 112 can be set arbitrarily.

[0035] <Disassembled state> Referring to Figures 3 and 4, the disassembled state of the structural members will be explained. The disassembled state includes the state in which the magnetic force of the structural members is demagnetized and separated into individual structural members, and the state in which the magnetic force of the structural members is demagnetized and the connected state of the structural members is maintained. Note that in a vehicle, for example, the structural members are in a disassembled state when it is in transport or not moving.

[0036] Referring to Figure 3, the state in which each structural member is separated will be explained in detail. As shown in Figure 3, in the connected state, the end face at end R2 of structural member 111 and the end face at end R1 of structural member 112 are connected by magnetic force. When structural members 111 and 112 are demagnetized, the connected state shown in Figure 3 is released, and structural members 111 and 112 can be separated. Therefore, the vehicle can be disassembled into structural members 11 and transported. In addition, since the vehicle can be disassembled into structural members 11, recycling is also easy.

[0037] Referring to Figure 4, the state in which the structural members are connected will be explained in detail. As shown in Figure 4, in the connected state, the end R2 of structural member 111 is fitted into the end R1 of structural member 112 and connected. When structural members 111 and 112 are demagnetized, the magnetic force acting between structural members 111 and 112 is lost, but the state in which the end R2 of structural member 111 is fitted into the end R1 of structural member 112 can be maintained.

[0038] Here, during operation, the magnetic force used to maintain the coupling state of vehicle 10 may attract and adhere metal fragments, such as iron filings or metal debris. As a result, vehicle 10 may rust due to galvanic corrosion or galvanic corrosion. In contrast, when the structural members are separated, the structural members lose their magnetism, and the metal fragments are shaken off by their own weight.

[0039] Therefore, by temporarily demagnetizing the structural members of vehicle 10 and putting it into a disassembled state, the occurrence of rust can be suppressed. Furthermore, even in the disassembled state, vehicle 10 maintains the state in which the end R2 of structural member 111 is fitted to the end R1 of structural member 112, so it can be easily returned to the connected state shown in Figure 4 simply by applying current again. In addition, by temporarily putting vehicle 10 into a disassembled state, it is also possible to reduce the power consumption of the power source (fuel cell).

[0040] The above describes an example of suppressing rust formation in the vehicle 10 by demagnetizing the structural members. In the coupled state, if the amount of metal pieces attracted to the structural members of the vehicle 10 exceeds a predetermined amount, the current flowing through the coil may be reduced. By using such a configuration, the amount of metal pieces attracted during operation (coupled state) can be reduced, and rust formation in the vehicle 10 can be suppressed.

[0041] Furthermore, the inverter 13 shown in Figure 1 may be controlled to apply current to the coils so that the structural members 11 are connected when the vehicle is in motion. Alternatively, the inverter 13 shown in Figure 1 may be controlled to stop applying current to the coils so that the structural members 11 are separated when the vehicle is not in motion. However, the inverter 13 is not limited to controlling the application of current to the coils to stop; it may also control the direction of the current flowing through each of the coils in the opposite direction, heat the structural members 11 to a temperature above the Curie temperature, or apply different types of current.

[0042] Figures 3 and 4 illustrate the connected and disconnected states, assuming that the coil is always wound around structural members 111 and 112. However, the configuration is not limited to this, and may be as follows.

[0043] Alternatively, coils may be wound around structural members 111 and 112 to magnetize them, and then the coils may be removed from structural members 111 and 112 to connect them. Alternatively, coils may be wound around structural members 111 and 112 to demagnetize them, and then the coils may be removed from structural members 111 and 112 to separate them. In this way, the coils may be wound around structural members 111 and 112 and removed each time they are magnetized and demagnetized, allowing structural members 111 and 112 to be in a connected state and a separated state.

[0044] Thus, in the vehicle according to Embodiment 1, the structural members can be magnetized. Therefore, even if the vehicle is transported to the site in separate structural members, the structural members can be connected at the site. Furthermore, in the vehicle according to Embodiment 1, the structural members can be demagnetized. This makes it possible to release the connection between the structural members. Therefore, the vehicle can be disassembled into structural members for transport, increasing transport efficiency. In other words, in the vehicle according to Embodiment 1, the state of magnetized and demagnetized structural members can be reversibly changed, so the structural members can be easily separated and connected / disassembled at any time, anywhere.

[0045] <Connection decomposition method> Next, the method for connecting and disassembling according to Embodiment 1 will be described. Figure 5 is a flowchart showing the method for connecting and disassembling structural members according to Embodiment 1.

[0046] The method for connecting structural members will now be explained. An electric current is applied to coils wrapped around both ends of the structural members (step ST11). This magnetizes the structural members. Next, the magnetized structural members are connected (step ST12). This results in the connected state shown in Figures 3 and 4.

[0047] The method for connecting structural members will now be explained. The application of current to the coils wrapped around both ends of the structural member is stopped (step ST13). This demagnetizes the structural member. Next, the magnetized structural member is disassembled (step ST14). This results in a disassembled state.

[0048] Thus, the method for connecting and disassembling structural members according to Embodiment 1 allows the structural members to be magnetized. Therefore, even if the vehicle is transported to the site in separate structural members, the structural members can be connected at the site. Furthermore, the method for connecting and disassembling structural members according to Embodiment 1 allows the structural members to be demagnetized. This makes it possible to release the connection between the structural members 11. Therefore, the vehicle can be disassembled into structural members 11 for transport, increasing transport efficiency. In other words, the method for connecting and disassembling structural members according to Embodiment 1 allows for reversible changes between the magnetized and demagnetized states of the structural members, so the structural members of the vehicle can be easily separated and connected / disassembled at any time and in any location.

[0049] The structural members described above are not limited to any particular material, but are preferably made of stainless steel, which has excellent rigidity and strength. The structural members may be ferritic stainless steel, austenitic stainless steel, or martensitic stainless steel. The structural members may also be stainless steel having one of the following structures: ferritic, austenitic, or martensitic, or a combination of these structures.

[0050] This disclosure is not limited to the embodiments described above, and may be modified as appropriate without departing from its intent. [Explanation of symbols]
