The drawer 130 is adapted to store a plurality of mobile devices (not shown), but the invention is not limited thereto. The support post 170 is configured to abut the ground plane 200 to provide support to the charging cart 100.

Please refer to FIG. 2, which is a cross-sectional view along line A of FIG. 1. As shown in FIG. 2 , the charging cart 100 further includes a lever 140 , a pulling structure 150 and a first guiding structure 160 . The door panel 120 has a space S therein, and the lever 140 is disposed in the space S of the door panel 120. The lever 140 has a fulcrum 141. The fulcrum 141 is pivotally connected to the door panel 120. The lever 140 has an opposite first end 142 and a second end 143, that is, the first end 142 and the second end 143 are rotatable relative to the fulcrum 141. The pull structure 150 connects the first end 142 of the lever 140 and the drawer 130. In the present embodiment, the pull structure 150 can be a cable, and one end of the cable connects the first end 142 of the lever 140 and the other end connects the drawer 130. The first guiding structure 160 is disposed in the cabinet 110 , and the first guiding structure 160 is away from the opening 112 of the cabinet 110 than the drawer 130 , and the pulling structure 150 at least partially resists the first guiding structure 160 . In the present embodiment, the first guiding structure 160 is a roller, but the invention is not limited thereto. The support post 170 pivotally connects to the second end 143 of the lever 140. The support post 170 is configured to be protruded from the space S of the door panel 120 below the door panel 120 by the second end 143 and abuts against the ground plane 200.

More specifically, in the present embodiment, the charging vehicle 100 further includes at least one sliding structure 180. As shown in FIG. 2, the sliding structure 180 is disposed in the cabinet 110, and is located in the opening 112 of the cabinet 110 and the first guiding structure. Between 160, the drawer 130 is slidably coupled to the sliding structure 180 such that the drawer 130 can be at least partially slid away from the cabinet 110 through the opening 112.

Please refer to pictures 3~4. 3 is a perspective view showing the charging cart of FIG. 1 in which the drawer 130 is pulled out from the cabinet 110. Figure 4 is a cross-sectional view taken along line B of Figure 3. As shown in FIGS. 3 to 4, when the drawer 130 is pulled out from the cabinet 110, the end of the pull structure 150 connecting the drawer 130 is also pulled out with the drawer 130. In the present embodiment, the pulling structure 150 bypasses the first guiding structure 160 and is at least partially pressed by the pulling structure 150. Therefore, the pulling structure 150 connects one end of the lever 140 by the guiding of the first guiding structure 160. The pull is also pulled toward the direction of the first guiding structure 160 such that the first end 142 of the lever 140 rotates relative to the fulcrum 141.

Specifically, the charging cart 100 further includes a second guiding structure 165. The second guiding structure 165 is disposed in the space S of the door panel 120 and is at least partially pressed by the pulling structure 150. It is to be noted that, as shown in FIGS. 2 and 4, the pulling structure 150 abuts the portion between the second guiding structure 165 and the first end 142 of the connecting lever 140, and the lever 140 forms an angle α with each other. That is to say, the angle α formed between the pulling structure 150 and the lever 140 is not 0 degrees, nor is it 180 degrees. In this way, when one end of the pulling structure 150 connecting the lever 140 is pulled toward the first guiding structure 160, the first end 142 of the lever 140 can be effectively rotated relative to the fulcrum 141. In the present embodiment, the second guiding structure 165 is a roller, but the invention is not limited thereto.

On the other hand, as shown in Figs. 2 and 4, the lever 140 and the support post 170 form an angle β with each other. That is, the lever 140 and the support post 170 The angle β formed between them is not 0 degrees, nor is it 180 degrees. In this way, when the first end 142 and the second end 143 of the lever 140 rotate relative to the fulcrum 141, the support post 170 will be effectively driven by the second end 143 to protrude from the space S of the door panel 120, so that the support post 170 can The ground plane 200 is biased against the ground 200.

In short, when the drawer 130 is pulled out from the cabinet 110, the support post 170 can protrude from the space S of the door panel 120 by the action of the pulling structure 150 and the lever 140 described above, and then abut the ground plane 200 and Ground 200 applies force. In this way, even if the overall center of gravity of the charging cart 100 is removed from the cabinet 110 due to the drawer 130 being pulled out from the cabinet 110, the charging cart 100 is obtained by the support post 170 abutting the ground surface 200 and applying force to the ground 200. The more stable support effectively reduces the chance of falling over, and thus reduces the likelihood of the user being crushed by the charging vehicle 100.

Moreover, the process of supporting the column 170 from the space S of the door panel 120 and then the grounding surface 200 does not require the use of an additional tool, and thus can be convenient for the user.

Structurally, in the present embodiment, the charging vehicle 100 further includes an elastic member 190. As shown in FIGS. 2 and 4, the elastic member 190 is disposed in the space S of the door panel 120, and the elastic member 190 has opposite fixed ends 191 and a connecting end 192. The fixed end 191 is fixed to the door panel 120, and the connecting end 192 is connected to one end of the second end 143 of the support post 170 pivoting the lever 140. As shown in FIG. 4, when the support post 170 is driven by the second end 143 to protrude from the space S of the door panel 120, the connecting end 192 of the elastic member 190 also moves outward with the support post 170 toward the space S. Since the fixed end 191 of the elastic member 190 is fixed In the door panel 120, the elastic member 190 is elongated as the support post 170 moves outwardly toward the space S, so that the elastic member 190 stores the elastic potential energy.

When the drawer 130 returns into the cabinet 110, as shown in Figures 1 and 2, the pull structure 150 is no longer pulled by the drawer 130, and the pulling structure 150 thus no longer pulls the lever 140. At this time, the elastic member 190 will release the stored elastic potential energy and return to the original length, and the support post 170 is also pulled back into the space S of the door panel 120 by the elastic member 190. In other words, when the elastic member 190 is in a natural state, the support post 170 is located in the space S of the door panel 120. In this way, the process of accommodating the support post 170 in the space S of the door panel 120 does not require the use of an additional tool, and thus can be convenient for the user. Furthermore, when the support column 170 is not required to support the charging cart 100, the support column 170 is housed in the space S to provide a space saving effect. In the present embodiment, the elastic member 190 is a spring, but the invention is not limited thereto.

In summary, the technical solution of the present invention has obvious advantages and beneficial effects compared with the prior art. Through the above technical solutions, considerable technological progress can be achieved, and the industrial use value is widely utilized, which has at least the following advantages:

(1) When the drawer is pulled out from the cabinet, the support post can protrude from the space S of the door panel by the above-described action on the pulling structure and the lever, and then abut against the ground plane and apply force to the ground. In this way, even if the overall center of gravity of the charging car is removed from the cabinet due to the drawer being pulled out from the cabinet body, the charging car is more stably supported by the support column against the grounding surface and the ground is effectively biased. The opportunity to pour can also reduce the possibility of the user being crushed by the charging car.

(2) The process of extending the support column from the space of the door panel and then the grounding surface, and the process of accommodating the support column in the space of the door panel, do not require the use of additional tools, and thus can be convenient for the user.

(3) When the support column is not required to support the charging car, it is more space-saving to store the support column in the space.
