The cabinet 110 has a working platform 112 located on a top of the cabinet 110 to provide the user with a working plane or carry a screen. The wheels 120 are disposed on the bottom of the cabinet 110, such that the mobile cart 100 can be moved by an external force.

The drawers 130 are disposed in the cabinet 110 for carrying or accommodating things, and are adapted to be pulled out of the cabinet 110 by the user to use or take out the things therein. Specifically, in the present embodiment, the drawers 130 include a keyboard tray 132 and a plurality of compartment drawers 134. The keyboard tray 132 and the compartment drawers 134 are all disposed in the cabinet 110, and can be pulled out of the cabinet 110. In addition, the working platform 112 of the cabinet 110 is located above the keyboard tray 132, and the keyboard tray 132 is located on the top of the cabinet 110. A keyboard and/or a mouse may be disposed on the keyboard tray 132 for the user to input commands for operating a computer. The compartment drawers 134 are located below the keyboard tray 132 for disposing pill boxes or accommodating things such as medical materials, components, etc.

The illumining unit 140 is disposed on the top of the cabinet 110 to illumine the drawer 130 being pulled out of the cabinet 110. In detail, the illumining unit 140 includes a keyboard tray illumining module 141 and a compartment drawer illumining module 142, wherein the keyboard tray illumining module 141 and the compartment drawer illumining module 142 are disposed on the bottom of the working platform 112. The keyboard tray illumining module 141 is configured to illumine the keyboard tray 132 being pulled out of the cabinet 110, and an effective illumining range of the keyboard tray illumining module 141 is located in the surrounding of the keyboard tray 132 being pulled out of the cabinet 110, as shown in FIG. 2. The compartment drawer illumining module 142 is configured to illumine any one of the compartment drawers 134 being pulled out of the cabinet 110, as shown in FIG. 3. The sensing unit 150 is disposed in the cabinet 110, for sensing whether the keyboard tray 132 or one of the compartment drawers 134 of the drawers 130 is pulled out of the cabinet 110 or not, and the sensing result of the sensing unit 150 is the basis for switching on the keyboard tray illumining module 141 or the compartment drawer illumining module 142 or not. The switch unit 160 is disposed on the top of the working platform 112 to control whether the illumining unit 140 is switched on or not manually.

FIG. 2 is a side view showing a keyboard tray illumining module of the mobile cart illumining a keyboard tray. Referring to FIG. 2, the keyboard tray illumining module 141 can respond to the signal from the sensing unit 150. Thus, when the sensing unit 150 senses the keyboard tray 132 being pulled out of the cabinet 110, the keyboard tray illumining module 141 is switched on to illumine the keyboard tray 132 being pulled out. In an embodiment, once a pulled-out length of the keyboard tray 132 from the cabinet 110 reaches one third of a total length L1 of the keyboard tray 132 or reaches two third of a length L2 of a keyboard disposing area 132a of the keyboard tray 132, the sensing unit 150 generates a signal to switch on the keyboard tray illumining module 141, which prevents an unwanted operation of the user. The directions of the aforementioned pulled-out length, the total length L1, and the length L2 are parallel to a pull direction D of the drawers 130. In the present embodiment, once the sensing unit 150 senses the keyboard tray 132 being pulled out of the cabinet 110, the sensing unit 150 outputs a signal to a control unit 170 so as to switch on the keyboard tray illumining module 141 by the control unit 170. The sensing unit 150 may include a contactless sensor (e.g. an optical sensor) or a contact sensor (e.g. a mechanical switch) for sensing the movement of the keyboard tray 132 relatively to the cabinet 110. In addition, a first optical axis A1 of the keyboard tray illumining module 141 may be inclined toward the pull direction of the drawers 130 with respect to the carrying surface of the keyboard tray 132 or with respect to the ground G where the wheels 120 are located. In other words, a first angle θ1 is formed between the first optical axis A1 and the carrying surface of the keyboard tray 132. In the present embodiment, the first angle θ1 ranges from 15 degrees to 75 degrees, and preferably from 30 degrees to 60 degrees, to improve the illumination effect.

FIG. 3 is a side view showing a compartment drawer illumining module of the mobile cart illumining one of the compartment drawers. Referring to FIG. 3, in the present embodiment, the compartment drawer illumining module 142 can respond to the signal from the sensing unit 150. Hence, when the sensing unit 150 senses one of the compartment drawers 134 being pulled out of the cabinet 110, the compartment drawer illumining module 142 is switched on to illumine the compartment drawer 134 being pulled out of the cabinet 110. In an embodiment, once a pulled-out length of the compartment drawer 134 from the cabinet 110 reaches a half of a total length L3 of the compartment drawer 134, the sensing unit 150 generates a signal to switch on the compartment drawer illumining module 142, which prevents an unwanted operation of the user. The directions of the aforementioned pulled-out length and the total length L3 are parallel to a pull direction D (as shown in FIG. 2) of the drawers 130. In the present embodiment, when the sensing unit 150 senses the compartment drawer 134 being pulled out of the cabinet 110, the sensing unit 150 outputs the signal to the control unit 170 so as to switch on the compartment drawer illumining module 142 by the control unit 170. In addition, a second angle θ2 is formed between a second optical axis A2 of the compartment drawer illumining module 142 and the ground G where the wheels 120 are located. The second angle θ2 ranges from 90 degrees to 120 degrees, and preferably is 90 degrees. In other words, the second optical axis A2 of the compartment drawer illumining module 142 may be perpendicular to the ground G where the wheels 120 are located to improve the illumination effect. The range of the light divergence angle of the compartment drawer illumining module 142 is between 30 degrees and 60 degrees. However, the disclosure does not limit the range of the light divergence angle of the compartment drawer illumining module 142, which may be varied according to using requirement.

In the present embodiment, since the higher drawer 130 (i.e. the keyboard tray 132) is closer to the keyboard tray illumining module 141, while the lower drawer 130 (i.e. the compartment drawer 134) is far away from the keyboard tray illumining module 141 and the compartment drawer illumining module 142, brightness of the keyboard tray illumining module 141 may be less than brightness of the compartment drawer illumining module 142 to comply with practical application and save electric power.

In an embodiment, the mobile cart 100 may further comprise a switch unit 160 disposed on the cabinet 110 (e.g. on the working platform 112 as shown in FIG. 1) and electrically coupled to the keyboard tray illumining module 142 and the compartment drawer illumining module 142. Therefore, the user can trigger the switch unit 160 by fingers to switch on the keyboard tray illumining module 141 for illumining the keyboard tray 132 being pulled out, as shown in FIG. 2, or to switch on the compartment drawer illumining module 142 for illumining the compartment drawer 134 being pulled out, as shown in FIG. 3. In the case of disposing the switch unit 160, the sensing unit 150 may be omitted, and the keyboard tray illumining module 141 and the compartment drawer illumining module 142 can be switched on or off merely by the switch unit 160.

In an embodiment, the sensing result of sensing the higher drawer 130 (i.e. the keyboard tray 132) by the sensing unit 150 can be used to switch the keyboard tray illumining module 141 on or off, while the switch unit 160 can be triggered by the user to switch the compartment drawer illumining module 142 on or off. In an embodiment, the sensing result of sensing the lower drawer 130 (i.e. the compartment drawer 134) by the sensing unit 150 can be used to switch the compartment drawer illumining module 142 on or off, while the switch unit 160 can be triggered by the user to switch the keyboard tray illumining module 141 on or off.

In summary, according to the aforementioned embodiments of the disclosure, the drawer being pulled out of the cabinet can be illumined by the illumining unit in an environment without sufficient illumination, such that the user can see the contents in the drawer clearly to ensure the work can be normally performed. The sensing unit can sense whether the drawer (e.g. the keyboard tray or one of the compartment drawers) is pulled out of the cabinet or not, for switching on the illumining unit to illumine the drawer being pulled out of the cabinet accordingly. The switch unit can also be triggered to switch on the illumining unit to illumine the drawer being pulled out of the cabinet. The illumining unit may include a keyboard tray illumining module and a compartment drawer illumining module for illumining the keyboard tray and the compartment drawers respectively.
