Summary of the Invention

Problems to be Solved by the Invention

[0004] The inventors have found the following problems. In the vehicle disclosed in Non-Patent Document 1 described above, since it is packaged and transported in a disassembled state for automotive parts, there is a problem that it takes time to assemble at the destination.

[0005] This disclosure has been made in view of such circumstances, and provides a vehicle that is easy to assemble at the destination.

Means for Solving the Problems

[0006] The vehicle according to this disclosure is A vehicle body in which a power unit that houses at least the vehicle's power source and a front-rear section to which at least one of the front wheels and rear wheels is attached are connected via a linkage mechanism, The link mechanism has a fastening portion between the power unit and the front and rear sections, and a guide hole that slides the fastening portion to a predetermined position. By sliding the fastening portion along the guide hole, the configuration can be reversibly changed between a driving configuration in which the power unit and the front and rear portions can travel while maintaining a flat state, and a transport configuration in which the front and rear portions can be transported while maintaining a state in which they are folded toward the power unit with the space between the front and rear portions and the power unit as a fold.

[0007] In the press vehicle according to this disclosure, the transport mode and the driving mode can be reversibly changed by sliding the fastening part along the guide hole. This configuration facilitates assembly at the destination.

[0008] At least one of the power unit and the front and rear sections may have a honeycomb structure. This configuration can improve the strength of at least one of the power unit and the front and rear sections. Therefore, deformation of the front and rear sections and the power unit due to impacts during transportation and driving can be suppressed.

[0009] Furthermore, the vehicle may have at least two passenger compartments including doors for the driver to get in and out, and at least one front and rear section and one power unit, for a total of four units. In the driving configuration, the front and rear sections and the power units are extended linearly so as to be adjacent to each other, and the passenger compartments are connected to the front and rear sections or the power units via the link mechanism in a direction perpendicular to the extension direction. In the transport configuration, the passenger compartments may be folded toward the power unit with a fold between them and the front and rear sections or the power unit, so that the passenger compartments are arranged opposite each other and form a hexahedron located on the sides. With this configuration, the vehicle 20 can be stacked when loaded into a transport container, thus increasing transport efficiency and reducing transport costs.

[0010] The vehicle is equipped with a first reinforcing member and a second reinforcing member that are removable depending on the vehicle configuration. In the transport configuration, the first reinforcing member sandwiches the front and rear sections and the power unit, thereby maintaining the front and rear sections in a bent state toward the power unit. In the driving configuration, the second reinforcing member sandwiches the front and rear sections and the power unit, thereby maintaining the power unit and the front and rear sections in a flat state. This configuration makes it possible to suppress deformation of the front and rear sections FR1 and the power unit P1 due to impacts during transport and driving.

[0011] A vehicle body in which a power unit that houses at least the vehicle's power source and a front-rear section to which at least one of the front wheels and rear wheels is attached are connected via a linkage mechanism, In cross-section, the link mechanism is such that the U-shaped cross-section of the front and rear section engages with the U-shaped cross-section of the power unit, allowing for rotation. By rotating the front and rear sections around the link mechanism, the configuration can be reversibly changed between a transport configuration in which the front and rear sections are folded towards the power unit with a fold between them, and a travel configuration in which the power unit and the front and rear sections remain flat and can travel.

[0012] In the press vehicle described herein, the transport mode and the driving mode can be reversibly changed by rotating the front and rear sections around a link mechanism, making assembly at the destination easy. [Effects of the Invention]

[0013] This disclosure makes it possible to provide vehicles that are easy to assemble at the destination. [Brief explanation of the drawing]

[0014] [Figure 1] This is an explanatory diagram illustrating the changes in the form of a vehicle according to Embodiment 1. [Figure 2] This figure shows the changes in the form of the vehicle according to Embodiment 1. [Figure 3] This is a diagram showing an example of a linkage mechanism. [Figure 4] This diagram shows the reinforcing members in the driving and transport modes. [Figure 5] This is an xy-plan view showing the driving configuration of the vehicle according to Embodiment 1. [Figure 6] This is an explanatory diagram illustrating the changes in the form of a vehicle according to Embodiment 2. [Modes for carrying out the invention]

[0015] The present disclosure will be described below through embodiments of the invention, but the invention claimed is not limited to the following embodiments. Furthermore, not all of the configurations described in the embodiments are necessarily essential for solving the problem. For clarity of explanation, the following descriptions and drawings have been omitted and simplified as appropriate. In each drawing, the same elements are denoted by the same reference numerals, and redundant explanations have been omitted where necessary.

[0016] It should be noted that the right-handed xyz Cartesian coordinate system shown in the diagram is merely a convenient representation for explaining the positional relationships of the components. Typically, the positive z-axis is vertically upward, and the xy-plane is horizontal.

[0017] (Embodiment 1) <Vehicle First, referring to FIG. 1, the configuration of the vehicle according to Embodiment 1 will be described. FIG. 1 is an explanatory diagram for explaining the morphological changes of the vehicle according to Embodiment 1. The upper part of FIG. 1 shows the traveling form of the vehicle and is an xy plan view. The lower part of FIG. 1 shows the transportation form of the vehicle and is an xz plan view. The vehicle 10 is typically transported in the transportation form, assembled at the transportation destination, changed to the traveling form, and travels in the traveling form.

[0018] As shown in FIG. 1, the vehicle 10 includes a power unit P1 and front rear parts FR1, FR2. The power unit P1 mounts at least the power source of the vehicle body. In the example shown in FIG. 1, the power unit P1 mounts a battery 40.

[0019] Although not shown in FIG. 1, the power unit P1 may mount a power source of the vehicle 10, such as a transaxle or a motor. Further, the power unit P1 may mount vehicle parts (such as a steering wheel described later) required in the traveling form and tools required when changing the form. Although not shown in FIG. 1, the seat of the vehicle 10 is arranged above the battery 40.

[0020] In the example shown in FIG. 1, the vehicle 10 includes one power unit P1 and two front rear parts FR1, FR2. As shown in FIG. 1, the front rear part FR1 and the front rear part FR2 are arranged so as to sandwich the power unit P1 in the front rear direction of the vehicle.

[0021] At least one of the front wheels and the rear wheels is attached to the front rear part FR1 and the front rear part FR2. In the example shown in FIG. 1, the front wheel FT is attached to the front rear part FR1 and the rear wheel RT is attached to the front rear part FR2.

[0022] Furthermore, the front and rear sections FR1 and FR2 may be configured such that the front wheels FT and rear wheels RT are not attached during transport, and are attached when assembled at the destination to transform into a driving configuration. In this case, the front wheels FT and rear wheels RT may be transported together with the vehicle 10, or they may be procured locally.

[0023] The front and rear sections FR1 and FR2 may have a steering wheel and accelerator pedal attached, or they may be configured to have a steering wheel and accelerator pedal attached when assembled at the destination and converted into a driving configuration. The front and rear sections FR1 and FR2 become part of the pallet in the transport configuration and become a ladder frame in the driving configuration.

[0024] The power unit P1 and the front and rear sections FR1 and FR2 are connected via a linkage mechanism. In the example shown in Figure 1, the distance C1 between the power unit P1 and the front and rear section FR1 is connected by a linkage mechanism. The distance C2 between the power unit P2 and the front and rear section FR2 is connected by a linkage mechanism. The driving mode, transport mode, and details of the linkage mechanism of the vehicle 10 will be described below.

[0025] <Training style> As shown in the upper part of Figure 1, the vehicle 10 is in a driving configuration in which the power unit P1 and the front and rear sections FR1 and FR2 maintain a flat surface. For example, the driver sits in the seat of the power unit P1 (not shown in Figure 1) and operates the vehicle 10 by operating the steering wheel and accelerator pedal attached to the front and rear section FR1. In this case, the front and rear section FR2 may be used as a cargo bed.

[0026] <Transportation form> As shown in the lower part of Figure 1, the vehicle 10 maintains a transportable configuration in which the front and rear sections FR1 and FR2 are folded toward the power unit P1, with C1 and C2 between the power unit P1 and the front and rear sections FR1 and FR2 serving as folds.

[0027] More specifically, as shown in the lower part of Figure 1, the front and rear section FR1 is folded towards the power unit P1, with C1 as the fold line. Similarly, the front and rear section FR2 is folded towards the power unit P1, with C2 as the fold line. In other words, in transport configuration, the front and rear sections FR1 and FR2 are arranged opposite each other, forming a U-shape as shown in the lower part of Figure 1.

[0028] Generally, vehicles are loaded into transport containers in their operational state, meaning that one vehicle is loaded per transport container. However, in the case of the vehicle 10 according to Embodiment 1, it is loaded into the transport container in the transport configuration shown in the lower part of Figure 1. Therefore, multiple vehicles 10 can be loaded into a transport container, resulting in higher transport efficiency and reduced transport costs.

[0029] Furthermore, in the transport configuration shown in the lower part of Figure 1, the battery 40 mounted on the power unit P1 can have its impact during transport suppressed by the front and rear sections FR1 and FR2. In this transport configuration, the width, depth, and height dimensions can be arbitrarily set to match the dimensions of the container.

[0030] <Link mechanism> The link mechanism between the power unit P1 and the front and rear sections FR1 and FR2 will be explained with reference to Figures 2 and 3. Figure 2 is a diagram showing the changes in the form of the vehicle according to Embodiment 1. Figure 3 is a diagram showing an example of the link mechanism.

[0031] An example of a linkage mechanism will be explained with reference to Figure 2. As shown in Figure 2, linkage mechanisms R1 and R2 are located between the power unit P1 and the front and rear sections FR1 and FR2, respectively, at C1 and C2. Since linkage mechanisms R1 and R2 have similar configurations, linkage mechanism R1 will be described below.

[0032] As shown in Figure 2, the link mechanism R1 has a fastening section T1 and a guide hole H1. The fastening section T1 fastens the power unit P1 and the front rear section FR1. The fastening section T1 is typically composed of a bolt and nut and is configured to be tightened and loosened.

[0033] The guide hole H1 has an L-shape. The fastening portion T1 can slide from one end of the L-shape of the guide hole H1 to the other end by loosening the bolt and nut. In other words, the guide hole H1 can be described as a hole that guides the fastening portion to slide to a predetermined position.

[0034] Furthermore, the link mechanism is not limited to the example shown in Figure 2; the link mechanism shown in Figure 3 may also be used. Figure 3 is a cross-sectional view of the link mechanism, and this link mechanism can be used as a substitute for the link mechanism shown in Figure 2.

[0035] As shown in Figure 3, in cross-section, the link mechanism R3 has a U-shaped cross-section of the power unit P1 fitted with the U-shaped cross-section of the front / rear section FR1 (FR2). The fastening section T3 fastens the power unit P1 and the front / rear section FR1 (FR2). The fastening section T3 is typically composed of bolts and nuts, and the front / rear section FR1 (FR2) is configured to be rotatable around the link mechanism R3 (central axis C3). In the U-shaped cross-section of the power unit P1, the central part is provided linearly parallel to the y-axis direction, and the side parts are provided parallel to the z-axis direction. In the U-shaped cross-section of the power unit P1, both ends of the central part are curved relative to the central part, and the side parts are provided. The U-shaped cross-section of the front / rear section FR1 (FR2) is similar.

[0036] <Morphological changes> Next, referring to Figure 2, we will explain the change in the vehicle 10's form from driving mode to transport mode. In Figure 2, step ST1 shows the driving mode, and step ST4 shows the transport mode.

[0037] As shown in step ST1 of Figure 2, when the vehicle 10 is in driving mode, the power unit P1 and the front and rear sections FR1 and FR2 maintain a flat state. In the link mechanism R1, the fastening portion T1 is tightened and fixed at one end of the L-shaped guide hole H1.

[0038] First, the fastening of the fastening part T1 in the link mechanism R1 is loosened. Then, as shown in step ST2 in Figure 2, the fastening part T1 slides from one end of the L-shape of the guide hole H1 toward the shorter end (the center of the L-shape). As a result, as shown in step ST2 in Figure 2, the power unit P1 moves in the negative z-axis direction.

[0039] Next, as shown in step ST3 of Figure 2, the fastening portion T1 slides from the shorter end (center of the L-shape) of the L-shaped guide hole H1 toward the other end. That is, the front rear portion FR1 slides in the negative x-axis direction relative to the power unit P1, and the front rear portion FR2 slides in the positive x-axis direction relative to the power unit P1. As a result, as shown in step ST3 of Figure 2, the front rear portion FR1 becomes capable of being bent toward the power unit P1.

[0040] Next, as shown in step ST4 of Figure 2, the front rear section is folded toward the power unit, with the fold line between the front rear section and the power unit. More specifically, the front rear section FR1 is folded toward the power unit P1, with the fold line C1 between the front rear section FR1 and the power unit P1. Also, the front rear section FR2 is folded toward the power unit P1, with the fold line C2 between the front rear section FR2 and the power unit P1. As a result, the front rear sections FR1 and FR2 of the vehicle 10 are positioned opposite each other.

[0041] To maintain this state, the fastening portion T1 in the link mechanism R1 is tightened and fixed at the other L-shaped end of the guide hole H1. In this way, the vehicle 10 changes from the driving mode (step ST1) to the transport mode (step ST4).

[0042] Figure 2 shows an example in which vehicle 10 changes from a driving mode (step ST1) to a transport mode (step ST4) by changing in the order of step ST1 to step ST4. Vehicle 10 can also change from a transport mode to a driving mode. For example, vehicle 10 changes from a transport mode to a driving mode by changing in the order of steps ST4, 3, 2, and 1 shown in Figure 2.

[0043] In this way, by sliding the fastening part T1 along the guide hole H1, the vehicle 10 can reversibly change between transport mode and driving mode. This configuration makes assembly at the destination easier. Also, even in the case of the link mechanism R3 shown in Figure 3, the vehicle 10 can reversibly change between transport mode and driving mode simply by rotating the front rear part FR1 (FR2) around the link mechanism R3 (central axis C3), making assembly at the destination easier.

[0044] <Reinforcement member> The reinforcing members will be explained with reference to Figure 4. Figure 4 shows the reinforcing members in the driving and transport modes. The upper part of Figure 4 shows the vehicle in the driving mode and is an xy plan view. The lower part of Figure 4 shows the vehicle in the transport mode and is an xz plan view. In Figure 4, the link mechanism is assumed to be the link mechanism R3 shown in Figure 3. Note that in Figure 4, for the sake of simplicity, the front and rear section FR1 and the power unit P1 are shown, and the front and rear section FR2 is omitted.

[0045] As shown in the upper part of Figure 4, the auxiliary member 21 has a triangular shape. The auxiliary member 21 is provided such that one side is parallel to the longitudinal direction of the power unit P1 and the other side is parallel to the longitudinal direction of the front rear section FR1. Two auxiliary members 21 are provided, sandwiching the front rear section FR1 and the power unit P1.

[0046] By inserting a bolt into the hole h2 and tightening a nut while the auxiliary member 21 is sandwiching the front / rear section FR1 and the power unit P1, the front / rear section FR1 can be maintained in a bent state toward the power unit P1. This prevents deformation of the front / rear section FR1 and the power unit P1 due to impacts during transport. It also mitigates the impact on the battery 40 (see Figure 1) during transport.

[0047] As shown in the lower part of Figure 4, the auxiliary member 22 has a rectangular shape. The auxiliary member 22 is provided so that its long side is parallel to the longitudinal direction of the power unit P1 and the front rear section FR1. Two auxiliary members 22 are provided, sandwiching the front rear section FR1 and the power unit P1.

[0048] By inserting a bolt into the hole h3 and tightening a nut while the auxiliary member 22 sandwiches the front / rear section FR1 and the power unit P1, the power unit P1 and the front / rear section FR1 can be kept flat. This suppresses deformation of the front / rear section FR1 and the power unit P1 due to impacts during driving. In addition, it can alleviate the stress applied to the fastening section T3 during driving.

[0049] Figure 4 illustrates an example of attaching reinforcing members, assuming the link mechanism is the link mechanism R3 shown in Figure 3. However, the method is not limited to this, and the reinforcing members may also be attached when the link mechanism is the link mechanism R1 shown in Figure 2. Note that auxiliary member 21 is referred to as the first reinforcing member, and auxiliary member 22 is referred to as the second reinforcing member.

[0050] <Honeycomb structure> The honeycomb structure of the power unit and the front and rear sections will be explained with reference to Figure 5. Figure 5 is an xy plan view showing the driving configuration of the vehicle according to Embodiment 1. In Figure 5, the configuration is the same as shown in Figure 1, except that the power unit P1 and the front and rear sections FR1 and FR2 have a honeycomb structure, so the explanation will be omitted.

[0051] As shown in Figure 5, the vehicle 10 has a honeycomb structure H10 in the power unit P1 and the front and rear sections FR1 and FR2. However, it is not limited to this, and the vehicle 10 may be configured such that at least one of the power unit P1 and the front and rear sections FR1 and FR2 has a honeycomb structure H10.

[0052] The vehicle 10 can be made lighter and stronger by having a honeycomb structure H10 in at least one of the power unit P1 and the front and rear sections FR1 and FR2. Therefore, deformation of the front and rear section FR1 and the power unit P1 due to shocks during transport and driving can be suppressed. In addition, shocks to the battery 40 (see Figure 1) during transport and driving can also be mitigated.

[0053] Furthermore, since the vehicle 10 has a honeycomb structure H10 in at least one of the power unit P1 and the front and rear sections FR1 and FR2, the holes in the honeycomb act as air passages, preventing moisture from accumulating near the battery 40 during transport. This prevents rusting of the battery 40. In addition, the battery 40, which heats up during operation, can be air-cooled.

[0054] The power unit P1 and the front and rear sections FR1 and FR2 are not limited to a honeycomb structure, but may also be configured with braces, grids, or plates.

[0055] Thus, the vehicle 10 according to Embodiment 1 has a link mechanism R1 that includes a fastening portion T1 and a guide hole H1. By sliding the fastening portion T1 along the guide hole H1, the vehicle 10 can reversibly change between transport mode and driving mode. This configuration facilitates assembly at the destination.

[0056] (Embodiment 2) Next, the configuration of the vehicle according to Embodiment 2 will be described with reference to Figure 6. Figure 6 is an explanatory diagram for illustrating the changes in the form of the vehicle according to Embodiment 2. The upper part of Figure 1 shows the vehicle's driving configuration and is an xy-plane view. The lower part of Figure 1 shows the vehicle's transport configuration and is an xz-plane view. Typically, the vehicle 20 is transported in transport configuration, assembled at the destination, and then transformed into a driving configuration.

[0057] Vehicle 20, shown in Figure 6, differs from vehicle 10, shown in Figure 1, in that it includes a front / rear section FR3 and passenger compartments B1 and B2. The configuration of the front / rear section FR3 in vehicle 20 is the same as that of the front / rear sections FR1 and FR2, so its explanation is omitted.

[0058] As shown in Figure 6, the vehicle 20 comprises two passenger compartments B1 and B2, one power unit P1, and three front and rear sections FR1, FR2, and FR3. The passenger compartments B1 and B2 shown in Figure 6 include at least a door for the driver to get in and out.

[0059] Vehicle 20, like vehicle 10, can reversibly change between transport mode and driving mode. The method of changing the mode of vehicle 20 is the same as that of vehicle 10 shown in Figure 2, so the explanation will be omitted. The transport mode and driving mode of vehicle 20 will be described below.

[0060] <Training style> As shown in the upper part of Figure 6, the vehicle 20 extends linearly in the positive x-axis direction in the order of front rear section FR1, power unit P1, front rear section FR3, and front rear section FR2. Front rear section FR1, power unit P1, front rear section FR3, and front rear section FR2 extend adjacent to each other. The passenger sections B1 and B2 are connected to the power unit P1 via a link mechanism (not shown in Figure 6) in a direction perpendicular to the extension direction.

[0061] As shown in the upper part of Figure 6, the vehicle 10 is in a driving configuration in which the front and rear section FR1, the power unit P1, the front and rear section FR3, and the front and rear section FR2 maintain a flat state. In the upper part of Figure 6, for the sake of explanation, the state in which the passenger sections B1 and B2 are parallel to the xy plane is shown, but in the driving configuration, the vehicle 20 is assembled so that the passenger sections B1 and B2 are parallel to the xz plane. The passenger sections B1 and B2 are then connected by, for example, a pipe (not shown in Figure 6) to form the roof of the vehicle. Alternatively, the passenger sections B1 and B2 may be connected by, for example, a pipe (not shown in Figure 6) and covered with cloth to form the roof of the vehicle.

[0062] The driver sits in the seat of the power unit P1 (not shown in Figure 1) and operates the vehicle 20 by operating the steering wheel and accelerator pedal mounted on the front and rear section FR1. In this case, the front and rear sections FR2 and FR3 may be used as cargo beds. As the vehicle 20 is composed of six sections, the cargo space can be increased.

[0063] <Transportation form> As shown in the lower part of Figure 6, the front rear section FR1 is folded towards the power unit P1, using C11 between the power unit P1 and the front rear section FR1 as a fold line. Also, the front rear section FR2 is folded towards the power unit P1, using C13 between the power unit P1 and the front rear section FR3 as a fold line. Furthermore, the front rear section FR2 is folded towards the front rear section FR3, using C15 between the front rear section FR2 and the front rear section FR3 as a fold line.

[0064] Then, using C12 between the passenger compartment B1 and the power unit P1 as a crease, the passenger compartment B1 is kept folded toward the power unit P1. Using C14 between the passenger compartment B2 and the power unit P1 as a crease, the passenger compartment B2 is kept folded toward the power unit P1.

[0065] In other words, as shown in the lower part of Figure 6, in the transport configuration, the vehicle 20 has its front and rear sections FR1 and FR3 facing each other, and the passenger section B1 (not shown in the lower part of Figure 6) and passenger section B2 facing each other. Also, in the transport configuration, the vehicle 20 has its power unit P1 and front and rear section FR2 facing each other, forming a hexahedron as shown in the lower part of Figure 6. In other words, in the transport configuration, the vehicle 20 has its power unit P1 as the bottom surface, its front and rear section FR2 as the top surface, and the passenger sections B1 and B2, and front and rear sections FR1 and FR3 as the sides, forming a hexahedron.

[0066] This configuration allows other vehicles 20 to be stacked on top of each other when the vehicles 20 are loaded into a transport container. This results in higher transport efficiency and reduced transport costs. Furthermore, in the transport configuration shown in the lower part of Figure 6, the battery 40 mounted on the power unit P1 is located inside the hexahedron, thus suppressing impact during transport.

[0067] In the vehicle 20 shown in Figure 6, an example was described in which the vehicle has one power unit P1 and three front and rear sections FR1, FR2, and FR3. However, it is not limited to this, and it may also have a configuration with two front and rear sections and two power units. In other words, the vehicle 20 may have a configuration with at least one front and rear section and at least one power unit, for a total of four.

[0068] Furthermore, in the vehicle 20 shown in Figure 6, an example was described in which the passenger compartment B1 is connected to the power unit P1 via a link mechanism (not shown in Figure 6) in a direction perpendicular to the extension direction. However, the vehicle is not limited to this, and the passenger compartment can be connected to the front / rear section or the power unit via a link mechanism in a direction perpendicular to the extension direction, as long as the passenger compartments are arranged opposite each other in the transport configuration.

[0069] As described above, in the vehicle 20 according to Embodiment 2, the front and rear sections and the power unit are adjacent to each other and connected by a link mechanism, extending in a straight line. The passenger section is connected to the power unit via a link mechanism in a direction perpendicular to the extension direction. With this configuration, the vehicle 20 becomes a hexagonal shape in transport form, and can be stacked when loaded into a transport container. Therefore, transport efficiency is high and transport costs can be reduced.

[0070] The materials used for the aforementioned vehicles 10 and 20 are, for example, metal materials or resin. There are no restrictions on the molding method for the aforementioned vehicles 10 and 20, and they can be molded, for example, by injection molding.

[0071] This disclosure is not limited to the embodiments described above, and may be modified as appropriate without departing from its intent. [Explanation of Symbols]
