DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 3, the base for a mobile surveillance device “A” comprises a base body 1, multiple first wheels 2, multiple second wheels 3, a top assembly 4, a fan 5, a first tube 6 and multiple solar panels.

The base body 1 includes a room 10 formed therein, and multiple batteries 8 and a control unit 9 are located in the room 10. The control unit 9 includes a circuit board, a charging part, an electric power adaptor, a power cable and a control cable. Heat will be generated during operation of the batteries 8 and the control unit 9. The base body 1 is made of metal boards.

The base body 1 is a triangular body and includes a first corner 11, a second corner 12 and a third corner 13. A handle 16 is connected to outside of the first corner 11 of the base body 1.

As shown in FIG. 4, the multiple first wheels 2 are connected to the underside of the base body 1. Preferably, the first wheels 3 include three brake wheels which are respectively perpendicular to three respective angle bisectors 14 of the first corner 11, the second corner 12 and the third corner 13.

A side board 15 is formed between the second corner 12 and the third corner 13. The multiple second wheels 3 are connected to the side board 15. The second wheels 3 include two directional wheels 31 and two universe-direction wheels 32. Each of the second wheels 3 includes a housing 33 connected thereto as shown in FIG. 6 to avoid the second wheels 3 from hitting pedestrians.

As shown in FIGS. 3 and 5, the top assembly 4 is shaped corresponding to the base body 1 and is located on the top of the base body 1. The top assembly 4 includes a first cover 41 and a second cover 42, wherein the first cover 41 is connected to the top of the base body 1. The second cover 42 includes multiple separators 411 on the underside thereof. The second cover 42 is mounted to the first cover 41, so that the separators 411 are located between the first and second covers 41, 42. A ventilation zone 43 is formed between the first and second covers 41, 42. A fan 5 is connected to the first cover 41 and located in the ventilation zone 43 so as to ventilate the room 10 and the ventilation zone 43, such that the heat mentioned above can be removed from the room 10. The first cover 41 includes multiple holes 412 formed to three sides thereof. The first cover 41 is secured to the top of the base body 1 by bolts (not shown) extending through the holes 412.

The fan 5 is electrically connected to the control unit 9 as shown in FIGS. 3 and 5, and is located between the first cover 41 and the second cover 42 to bring cool air through the ventilation zone 43 to remove the heat generated from the batteries 8 and the control unit 9.

As shown in FIGS. 2 and 5, the first end of the first tube 6 extends through the first and second covers 41, 42 and is inserted into the room 10. The second end of the first tube 6 extends beyond the top assembly 4. The first tube 6 is located at the first corner 11. A second tube 7 is retractably inserted into the second end of the first tube 6. A locking member 61 extends through the first tube 6 and secures the first tube 6 to the second tube 7. A transverse bar 71 is connected to the top end of the second tube 7 and a camera 91 is attached to the transverse bar 71.

A solar panel unit 44 as shown in FIGS. 7 and 8 is connected to the top assembly 4 and the solar panel unit 44 is electrically connected to the control unit 9. The solar panel unit 44 is composed of multiple solar panels 441 connected with each other by multiple hinges 442. The solar panel unit 44 is located on the top of the top assembly 4. The multiple solar panels 441 are folded to form a triangle shape assembly which is shaped as the base body 1. Each solar panel 441 includes multiple photons collected on a board and a frame 4412 enclosed to the board. When the solar panels 441 expand, the solar energy is transformed into electrical energy to charge the batteries 8 so that the mobile surveillance device “A” of the present invention does not city power.

As shown in FIGS. 9 and 10, another embodiment of the present invention shows that an expandable solar panel unit 45 is connected to the top assembly 4 and includes a first solar panel 451 and two second solar panels 452. The first solar panel 451 is connected to the top assembly 4, and the two second solar panels 452 respectively have a pivotal portion 46/47 which is pivotably mounted to the first tube 6, so that the first and second solar panels 451, 452 can be pivoted relative to the first tube 6. Each of the pivotal portions 46, 47 has a stop 461/471. Each of the first and second solar panels 451, 452 includes multiple photons 453 collected on a board and a frame 454 enclosed to the board. The first and second stops 461, 471 position the two second solar panels 452 at a desired angle. When the first and second solar panels 451, 452 expand, the solar energy is transformed into electrical energy to charge the batteries 8 so that the surveillance device of the present invention does not city power. When not in use, the first and second solar panels 451, 452 are folded to form a triangle shape assembly which is shaped as the base body 1.

As shown in FIGS. 4 and 6, the base body 1 can be positioned such that the second wheels 3 contact the ground. The base body 1 can be easily carried by holding the handle 16 and move the mobile surveillance device “A” of the present invention from place to another. The users decide whether the base body 1 stands on the first wheels 2 or the second wheels 3. The power cable and the control cable can be pulled via the second tube 7 and are connected to the camera 91.

When the mobile surveillance device “A” of the present invention is set at a desired position, the users move the base body 1 by releasing the first wheels 2 so that the range of surveillance of the camera 91 can be adjusted. After the range of surveillance of the camera 91 is set, the first wheels 2 which are the brake wheels are locked.

The top assembly 4 avoids rain from entering into the batteries 8 and the control unit 9. The solar panels absorb the heat of the sun light. The fan 5 as shown in FIG. 5 installed to the top assembly 4 removes the heat in the room 10 and delivers the heat from the ventilation zone 43 to reduce temperature in the room 10.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
