However, it should be understood that these practical details should not be used to limit the present disclosure. In other words, in some embodiments of the present disclosure, these practical details are not necessary. In addition, in order to simplify the drawings, some commonly used structures and components will be depicted in the drawings in a simple schematic manner.

Please refer to FIG. 1A and FIG. 1B. FIG. 1A is a side view of a vehicle 100 according to an embodiment of the present disclosure, wherein the second seat cushion 220 is in a flat position relative to the first seat cushion 210. FIG. 1B is another side view of the vehicle 100 in FIG. 1A, wherein the second seat cushion 220 is in an upright position relative to the first seat cushion 210. As shown in FIG. 1A and FIG. 1B, in the present embodiment, the vehicle 100 is a two-wheeled vehicle. Although the vehicle 100 in FIG. 1A and FIG. 1B is a two-wheeled vehicle, the present disclosure is not limited thereto. In actual application, the vehicle 100 may also be a vehicle with more than two wheels. In addition, although the vehicle 100 in FIG. 1A and FIG. 1B is a scooter-type transportation vehicle, the present disclosure is not limited thereto. In practical applications, the vehicle 100 may also be other straddle-type transportation vehicles.

As shown in FIG. 1A and FIG. 1B , in this embodiment, the vehicle 100 includes a vehicle body 110 and a seat cushion assembly 200. The vehicle body 110 has a vehicle compartment 111 (indicated by dotted lines). The seat cushion assembly 200 is disposed above the vehicle compartment 111 and includes a first seat cushion 210 and a second seat cushion 220. The first seat cushion 210 and the second seat cushion 220 are arranged in the front-rear direction of the vehicle 100. That is, the first seat cushion 210 is close to the front of the vehicle, and the second seat cushion 220 is close to the rear of the vehicle. The first seat cushion 210 includes a first cushion body 211, which is configured for a driver to sit on. The second seat cushion 220 includes a second cushion body 221, which is configured for a passenger to sit on. The first seat cushion 210 and the second seat cushion 220 cover the vehicle compartment 111 together.

Please refer to FIG. 2. FIG. 2 is a three-dimensional assembly diagram showing some components of the seat cushion assembly 200 and the cover plate 112 according to an embodiment of the present disclosure. As shown in FIG. 2, in this embodiment, the first seat cushion 210 further includes a first support plate 212 (only a portion is shown in the figure). The first support plate 212 is disposed on the vehicle compartment 111. The first support plate 212 is configured to selectively cover and open a portion of the opening of the vehicle compartment 111. For example, the front edge of the first support plate 212 is rotatably connected to the vehicle body 110, but the present disclosure is not limited thereto. The first pad 211 is disposed on the first supporting plate 212, and can be used by the driver to sit on the first supporting plate 212 when the first supporting plate 212 is covered on the vehicle compartment 111. For example, the material of the first pad 211 includes foam, but the present disclosure is not limited thereto.

As shown in FIG. 2 , in this embodiment, the second seat cushion 220 further includes a second support plate 222. The second support plate 222 is disposed on the vehicle compartment 111. The second cushion body 221 is disposed on the second support plate 222, and can be used for passengers to sit on when the second support plate 222 is covered on the vehicle compartment 111. For example, the material of the second cushion body 221 includes foam, but the present disclosure is not limited thereto.

Please refer to FIG. 3 and FIG. 4. FIG. 3 is a partial cross-sectional view of the components in FIG. 2 along line segment 3-3. FIG. 4 is a three-dimensional view of some components in FIG. 2, and FIG. 4 shows the side of the first seat cushion 210 facing the vehicle compartment 111. As shown in FIG. 3 and FIG. 4, in this embodiment, the first support plate 212 has a groove 212a. The groove 212a is formed on a side of the first support plate 212 away from the first pad 211 (that is, located on the side of the first support plate 212 facing the vehicle compartment 111). The first seat cushion 210 further includes a shaft 213, and the shaft 213 is located in the groove 212a. It can be seen that when the first supporting plate 212 is covered to the vehicle compartment 111 , the rotating shaft 213 is not exposed.

Please refer to Figure 5, Figure 6A and Figure 6B. Figure 5 is a side view of the second cushion 220 according to an embodiment of the present disclosure, wherein the second cushion 221 is represented by a dotted line. Figure 6A is a three-dimensional view of some components of the cushion assembly 200 in Figure 2. Figure 6B is another three-dimensional view of the components in Figure 6A. As shown in Figures 5 to 6B, in this embodiment, the second cushion 220 further includes a hinge structure 223. The hinge structure 223 is connected to the second support plate 222 and is located on a side of the second support plate 222 close to the first cushion 210. The hinge structure 223 extends into the groove 212a of the first support plate 212. The groove 212a provides enough space for the hinge structure 223 to rotate therein, so that the second seat cushion 220 can rotate relative to the first seat cushion 210 to respectively assume the flat configuration of FIG. 1A and the standing configuration of FIG. 1B. In addition, by extending the hinge structure 223 into the groove 212a without being exposed, the hinge structure 223 can be protected from unexpected damage or disassembly, thereby protecting the items in the vehicle compartment 111.

The hinge structure 223 includes a hinge portion 223a and a stop portion 223b. The hinge portion 223a is hinged to the shaft 213. The stop portion 223b is connected to the hinge portion 223a and forms a disassembly opening O with the hinge portion 223a.

Specifically, the hinge portion 223a is hook-shaped (i.e., the hinge portion 223a has an open end), so that it can hook the rotating shaft 213. The stopper portion 223b is in the shape of a baffle and is opposite to the open end of the hinge portion 223a to prevent the hinge portion 223a from detaching from the rotating shaft 213. Thus, when the hinge structure 223 is mounted on the rotating shaft 213, the hinge portion 223a and the stopper portion 223b surround the rotating shaft 213 together and are slidably coupled to the outer surface of the rotating shaft 213 together.

As shown in FIG. 6A and FIG. 6B , in this embodiment, the stopper 223b is configured to move relative to the hinge 223a to adjust the width W of the disassembly opening O (see FIG. 3 ), thereby selectively allowing or not allowing the shaft 213 to pass through the disassembly opening O. The hinge structure 223 can be made of an elastic material, such as plastic. Therefore, the stopper 223b can move relative to the hinge 223a by elastic deformation. When the stopper 223b is not deformed relative to the hinge 223a, as shown in FIG. 6A , the width W of the disassembly opening O is smaller than the diameter of the shaft 213, and therefore the disassembly opening O does not allow the shaft 213 to pass through. When the stopper 223b is deformed relative to the hinge 223a so that the width W of the disassembly opening O is greater than the diameter of the shaft 213, as shown in FIG. 6B, the disassembly opening O allows the shaft 213 to pass through. Thus, the second seat pad 220 of this embodiment can be quickly disassembled relative to the first seat pad 210.

In some embodiments, the aforementioned width W of the disassembly opening O may be defined as the shortest distance between the end of the hinge portion 223a and the stop portion 223b on a cross section perpendicular to the rotation axis 213 (such as the cross section shown in FIG. 3 ).

Please refer to Figure 6C. Figure 6C is another three-dimensional diagram showing the components in Figure 6A. As shown in Figure 6C, in this embodiment, the hinge structure 223 further includes a paddle 223c. The paddle 223c is connected to the stop portion 223b and is configured to be moved by the user's finger to drive the stop portion 223b to move relative to the hinge portion 223a. Specifically, referring to Figures 3 and 6C, the user can push the paddle 223c in the direction indicated by the thick arrow in Figure 6C. The stop portion 223b will be driven by the paddle 223c and move in a direction away from the end of the hinge portion 223a, so that the width W of the disassembly port O gradually increases. When the width W of the disassembly opening O increases to be larger than the diameter of the shaft 213 , the hinge portion 223 a can be removed from the shaft 213 .

Incidentally, the hinge portion 223a and the stop portion 223b are preferably formed in one piece. However, in practical applications, the hinge portion 223a and the stop portion 223b are not limited to two parts of a single elastic structure, but can also be two independent components connected by an elastic member (such as a spring).

In some embodiments, one of the groove 212a and the hinge structure 223 has at least one first engaging structure. The other of the groove 212a and the hinge structure 223 has at least one second engaging structure and at least one third engaging structure. When the first engaging structure is engaged with the second engaging structure, the second cushion 220 is positioned at a first position relative to the first cushion 210. When the first engaging structure is engaged with the third engaging structure, the second cushion 220 is positioned at a second position relative to the first cushion 210. The second cushion 220 at the first position is in a flat configuration relative to the first cushion 210, as shown in FIG. 1A. The second cushion 220 at the second position is in an upright configuration relative to the first cushion 210, as shown in FIG. 1B.

For example, as shown in FIG. 3, and with reference to FIG. 4 and FIG. 5, in this embodiment, the groove 212a has at least one positioning hole 212a1 (i.e., the aforementioned first engaging structure). The hinge structure 223 has at least one positioning protrusion 223d and at least one positioning protrusion 223e (i.e., the second engaging structure and the third engaging structure). When the positioning hole 212a1 is engaged with the positioning protrusion 223d, the second seat pad 220 is positioned at the first position relative to the first seat pad 210. When the positioning hole 212a1 is engaged with the positioning protrusion 223e, the second seat pad 220 is positioned at the second position relative to the first seat pad 210.

In some embodiments, the positioning hole 212a1 can also be changed to be disposed on the hinge structure 223, and the positioning protrusions 223d and 223e can be changed to be disposed in the groove 212a, and the aforementioned positioning effect can also be achieved. In some other embodiments, the positioning hole 212a1 of the groove 212a can also be changed to a protrusion, and the positioning protrusions 223d and 223e of the hinge structure 223 can be changed to holes, and the aforementioned positioning effect can also be achieved. In addition, the present disclosure does not limit the shape of the positioning protrusions 223d and 223e. The positioning protrusions 223d and 223e can be cylindrical, rectangular cylindrical, sheet-shaped, or any combination thereof. In addition, the user can increase or decrease the number of the positioning holes 212a1 and the positioning protrusions 223d and 223e according to needs to stably fix the position of the second seat pad 220.

As shown in FIG. 1B and FIG. 2, in this embodiment, the vehicle 100 further includes a cover plate 112. The cover plate 112 is disposed between the vehicle compartment 111 and the seat cushion assembly 200. The cover plate 112 is configured to cover the opening of the vehicle compartment 111. Thus, even if the second seat cushion 220 is arranged upright relative to the first seat cushion 210, the cover plate 112 can still prevent the space in the vehicle compartment 111 from being exposed.

As shown in FIG. 5 and in conjunction with FIG. 1A , in this embodiment, the second support plate 222 has two opposite edges. The hinge structure 223 extends from one edge (e.g., the front edge) of the second support plate 222. The second seat cushion 220 further includes a hook 224. The hook 224 is connected to the second support plate 222 and is adjacent to the other edge (e.g., the rear edge) of the second support plate 222. In addition, please refer to FIG. 7 , which is another three-dimensional diagram showing some of the components in FIG. 2. As shown in FIG. 7 , in this embodiment, the cover plate 112 has a slot 112a. The hook 224 of the second seat cushion 220 is configured to engage with the slot 112a to fix the second seat cushion 220 to the cover plate 112.

Specifically, as shown in FIG. 5 , the disassembly opening O formed by the stopper 223b and the hinge 223a is substantially oriented in a direction D1 away from the second support plate 222 (i.e., the left direction in FIG. 5 ). The hook 224 extends in a direction D2 opposite to the aforementioned direction D1 (i.e., the right direction in FIG. 5 ). Thus, when the second cushion 220 is in a flat configuration relative to the first cushion 210 as shown in FIG. 1A , the hinge structure 223 cannot be disassembled relative to the shaft 213 along the direction D2 in FIG. 5 due to the engagement between the hook 224 and the slot 112a (see FIG. 7 ).

In some embodiments, the hook 224 can be made of a flexible material, such as plastic, so that when the rear end of the second cushion 220 in FIG. 1A is lifted upward, the hook 224 will be elastically deformed and disengaged from the slot 112a, thereby allowing the second cushion 220 to rotate relative to the first cushion 210.

As shown in FIG. 7 , in this embodiment, the second cushion 220 further includes at least one bracket 225. Please refer to FIG. 5 , in this embodiment, the bracket 225 is connected to the second support plate 222 (via the hinge structure 223) and is located on a side of the hinge structure 223 away from the second support plate 222. In a direction parallel to the rotation axis 213, the width of the bracket 225 is greater than the width of the hinge structure 223. When the second cushion 220 is in an upright configuration relative to the first cushion 210 (as shown in FIG. 7 ), the second cushion 220 stands on the cover plate 112 with the bracket 225. Since the width of the bracket 225 in the direction parallel to the rotation axis 213 is greater than the width of the hinge structure 223 in the left-right direction of the vehicle 100, the stability of the second seat cushion 220 in the upright configuration can be increased.

It should be noted that two brackets 225 are shown in FIGS. 6A to 7 , respectively located on two sides of the hinge structure 223 . However, the present disclosure is not limited thereto. In some other embodiments, the second seat cushion 220 may also include only one bracket 225 .

As shown in FIG. 4 and FIG. 7 , in this embodiment, the first support plate 212 of the first cushion 210 further includes a fastening member 214, which is disposed on a side of the first support plate 212 away from the first cushion body 211. The cover plate 112 further includes a fastening device 112b, which is disposed on a side facing the first cushion 210. The fastening device 112b is configured to be fastened with the fastening member 214 to fix the first cushion 210. In this embodiment, the fastening member 214 is a U-shaped buckle ring, but the present disclosure is not limited thereto. In some other embodiments, the fastening member 214 can also be other shapes, and the fastening device 112b is disposed corresponding to the shape of the fastening member 214.

From the above detailed description of the specific implementation of the present disclosure, it can be clearly seen that according to the seat cushion assembly and the vehicle disclosed in the present disclosure, the second seat cushion has a hinge structure that can be hinged with the rotating shaft of the first seat cushion, so that the second seat cushion can be directly fixed on the first seat cushion and rotate relative to the first seat cushion. The hinge structure of the second seat cushion further includes a stopper that can move relative to the hinge part, so that the disassembly opening formed between the stopper and the hinge part can be elastically adjusted. Therefore, when the width of the disassembly opening is smaller than the rotating shaft of the first seat cushion, the rotating shaft cannot pass through the disassembly opening, so that the hinge structure cannot be disassembled from the rotating shaft. After the width of the disassembly opening is adjusted to be larger than the rotation axis of the first seat cushion, the rotation axis can pass through the disassembly opening without hindrance to separate the hinge structure from the rotation axis. In this way, the second seat cushion of the present disclosure can be quickly disassembled relative to the first seat cushion. In addition, the user can quickly adjust the configuration of the second seat cushion according to actual needs. When the user wants to carry passengers, the second seat cushion will be adjusted to a lying configuration. When the user wants to carry cargo, the user can directly rotate the second seat cushion to a standing configuration.

Although the present disclosure has been disclosed in the above implementation form, it is not intended to limit the present disclosure. Anyone skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be determined by the scope of the attached patent application.
