The following will describe in detail various embodiments of the present disclosure, and will be illustrated with drawings. In addition to these detailed descriptions, the present disclosure can also be widely implemented in other embodiments, and any easy replacement, modification, and equivalent changes of the embodiments are included in the scope of the present disclosure and are subject to the scope of subsequent patents. In addition, well-known steps or components are not described in the details to avoid unnecessary limitations of the present disclosure. Moreover, unless otherwise specified, the same component symbols in different drawings can be regarded as corresponding components.

Please refer to Figures 1A to 1C, which are schematic diagrams showing the switching of the loading board 130 of the electric vehicle 100 between the folded state and the unfolded state according to an embodiment of the present disclosure.

The electric vehicle 100 may be, for example, an electric scooter, which includes a vehicle body 110, a front wheel 121, a rear wheel 122, and a loading board 130. The vehicle body 110 includes a foot pedal 111, and the foot pedal 111 can be used for a user to place his feet to carry the user. The front wheel 121 and the rear wheel 122 are rotatably connected to the vehicle body 110 and are arranged at the front and rear of the foot pedal 111, so that the electric vehicle 100 can move on the road. The loading board 130 is connected to the vehicle body 110 and is suitable for moving relative to the foot pedal 111 to switch to a folded state or an unfolded state. As shown in Figure 1A, in the folded state, the loading board 130 is supported by the foot pedal 111 and is located on the foot pedal 111. At this time, the loading board 130 can be stacked on the foot pedal 111 for the user to place his feet to carry the user, and the driving function is realized when the user has no need to carry goods. As shown in Figure 1C, in the unfolded state, the loading board 130 is arranged behind the foot pedal 111. At this time, the loading board 130 allows the user to place goods on it, and at the same time, the user can place his feet on the foot pedal 111, thereby realizing the driving and carrying functions together.

As shown in FIG. 1B , the carrier 130 is allowed to move from the folded state shown in FIG. 1A to switch between states. Specifically, the carrier 130 can be connected to the vehicle body 110 via a pair of movable connecting rods ML, which are disposed on both sides of the foot pedal 111 to allow the carrier 130 to pivot relative to the vehicle body 110. By swinging the movable link ML (clockwise movement on the X-Z plane as shown in FIG. 1B ), the carrier 130 can be driven to release the support of the footrest 111 to move away from the footrest 111 and toward the rear of the footrest 111 until the carrier 130 is disposed behind the rear wheel 122, thereby switching to the unfolded state shown in FIG. 1C . Conversely, the carrier 130 is also allowed to move from the unfolded state shown in FIG. 1C to switch the state. Through the reverse swing of the movable link ML (counterclockwise movement on the X-Z plane of Figure 1B), the carrier 130 can be driven to move from behind the rear wheel 122 toward the footrest 111 until the carrier 130 is supported on the footrest 111, thereby switching to the folded state shown in Figure 1A. In other words, the movable link ML can swing relative to the footrest 111 so that the carrier 130 can switch to the folded state or the unfolded state.

In addition, the footrest 111 has an upper surface 111u for stepping. When the loading board 130 is in the unfolded state, the upper surface 111u can be exposed to provide a stepping area for the user when driving. The loading board 130 has a top surface 130t for placing objects and a bottom surface 130b opposite to the top surface 130t. When the loading board 130 is in the folded state, the bottom surface 130b can be attached to the upper surface 111u, so that the loading board 130 is stacked on the footrest 111, and the top surface 130t is used as the stepping area for the user when driving.

Please refer to Figures 2A~2B and 3. Figure 2A shows the electric vehicle 100 with its carrier plate 130 in an unfolded state from a side view, Figure 2B shows the electric vehicle 100 with its carrier plate 130 in a folded state from a side view, and Figure 3 shows the electric vehicle 100 with its carrier plate 130 in an unfolded state from a top view.

The electric vehicle 100 may further include at least one pair of auxiliary wheels, so that the carrier 130 can follow the vehicle body 110 and travel together with the front wheel 121 and the rear wheel 122 in the unfolded state. In this example, the electric vehicle 100 includes two pairs of auxiliary wheels 140. Each pair of auxiliary wheels 140 is connected to the carrier 130 and is disposed on both sides of the carrier 130. As shown in FIG. 2A, when the carrier 130 is in the unfolded state and the front wheel 121 and the rear wheel 122 contact the ground G, each pair of auxiliary wheels 140 also contacts the ground, and in the unfolded state, each pair of auxiliary wheels 140 is disposed on both sides of the pedal 111 and behind the rear wheel 122. As shown in FIG. 2B , when the loading board 130 is in the folded state and the front wheels 121 and the rear wheels 122 are in contact with the ground G, each pair of auxiliary wheels 140 does not contact the ground G, that is, the auxiliary wheels 140 are at a distance d from the ground G, and in the folded state, each pair of auxiliary wheels 140 is arranged on both sides of the pedal 111 and is located below the pedal 111.

In this embodiment, when the carrier 130 is in the unfolded state, at a top view angle (along the Z-axis direction), the upper surface 111u of the foot pedal 111 and the top surface 130t of the carrier 130 do not overlap in projection. However, the present disclosure is not limited to this. In other embodiments, at a top view angle, the upper surface 111u of the foot pedal 111 may partially overlap in projection with the top surface 130t of the carrier 130.

In addition, the two ends of the loading plate 130 corresponding to the front wheel 121 and the rear wheel 122 may each have a groove structure 130R. In this embodiment, the loading plate 130 has two groove structures 130R, namely, a front groove structure 131R corresponding to the front wheel 121 and a rear groove structure 132R corresponding to the rear wheel 122. In a direction parallel to the axial direction of the front wheel 121 or the rear wheel 122 (along the Y-axis direction), the width W1 of the front groove structure 131R and the width W2 of the rear groove structure 132R are greater than the width Wr of the rear wheel 122. In a direction parallel to the radial direction of the front wheel 121 or the rear wheel 122 (along the X-axis direction), the depth D2 of the rear groove structure 132R is greater than the depth D1 of the front groove structure 131R. In the folded state, the rear wheel 122 can be partially accommodated in the receiving space formed by the rear groove structure 132R, and the arm portion 112 of the vehicle body 110 corresponding to the front groove structure 131R can be partially accommodated in the receiving space formed by the front groove structure 131R; and in the unfolded state, the rear wheel 122 can be partially accommodated in the receiving space formed by the front groove structure 131R. In other words, through the design of the groove structure 130R, the loading board 130 can avoid the vehicle body 110 and the rear wheel 122, so as to switch between the folded state and the unfolded state without interference.

According to the above, the electric vehicle disclosed in the embodiment of the present disclosure has a loading board that can be switched between a storage state and an unfolded state, so that the user can realize the driving function when there is no need to load cargo, and realize the driving and loading functions when there is a need to load cargo. Therefore, the present disclosure can meet the needs of users of electric vehicles and solve safety issues.

Although the present disclosure has been disclosed as above by way of embodiments, it is not intended to limit the present disclosure. Those with ordinary knowledge in the technical field to which the present disclosure belongs can make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be subject to the scope of the patent application attached hereto.
