[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figures 1 to 4 In the utility model, a special vehicle compartment space expansion structure comprises a compartment body 1 and a through slot 2 opened on the right side thereof, a movable slot 3 is opened on the inner bottom wall of the compartment body 1, an expansion box 4 is slidably connected to the inner wall of the movable slot 3, the right side of the expansion box 4 passes through the through slot 2 and extends to the outside of the compartment body 1, and the inner top wall of the through slot 2 is opened with evenly distributed expansion slots 5, and the top of the expansion box 4 is fixedly connected with evenly distributed racks 6, and evenly distributed servo motors 7 are installed on the inner wall of the compartment body 1, and the output shaft of the servo motor 7 is meshed with the rack 6 through a gear, and two movable plates 8 are hinged on the inner wall of the expansion box 4, and a movable door 9 is installed on the movable plate 8, and a support mechanism 10 is arranged on the right side of the expansion box 4, wherein the movable plate 8 and the expansion box 4 are connected by a snap buckle.

[0022] The supporting mechanism 10 includes two electric push rods 1001 , which are installed on the right side of the expansion box 4 . A round ball 1002 is fixedly installed on the bottom end of the electric push rod 1001 , and a supporting base 1003 is sleeved on the outer side of the round ball 1002 .

[0023] The side of the movable groove 3 is in an inclined state, and a guide groove 15 is opened on the inner bottom wall of the movable groove 3, and the expansion box 4 is slidably connected to the inner wall of the guide groove 15.

[0024] During the driving of the special vehicle, the expansion box 4 is inside the car body 1, and the bottom of the expansion box 4 is inside the movable groove 3 and can slide inside the movable groove 3, but the gear and rack 6 on the top cooperate to lock the expansion box 4, and the movable plate 8 fits on the inner wall of the expansion box 4 so as not to affect the normal walking inside the special vehicle. When the special police vehicle stops, the user controls multiple groups of servo motors 7 to work at the same time, and the servo motor 7 drives the gear fixedly connected to it to start rotating. Driven by the gear, the rack 6 starts to move to the right, and the expansion box 4 moves rightward through the through groove 2 toward the outside of the car body 1. As the servo motor 7 continues to work After the expansion box 4 is fully expanded to the outside, the servo motor 7 stops locking the expansion box 4, and then the support mechanism 10 operates, and the electric push rod 1001 drives the bottom ball 1002 to move downward, and the support base 1003 moves down accordingly until it is completely in contact with the ground to provide support. If the special vehicle is on an inclined ground, one side of the support base 1003 contacts the ground first, and then as the electric push rod 1001 continues to press down, the support base 1003 gradually contacts the ground to complete the support. In subsequent actual use, the user can rotate the movable plate 8 to form a closed space inside the expansion box 4 and enter and exit through the movable plate 8, or keep it open for easy observation and response to emergencies.

[0025] In the utility model, the expansion box 4 inside the special vehicle can be expanded outward by driving the gear and rack 6 through the servo motor 7, so as to expand the internal space of the vehicle, and the box door of the expansion box 4 is hinged by the movable plate 8, so that in actual use, if the expansion box 4 is inside the vehicle body 1, it will not occupy space and affect the normal movement inside the vehicle body 1, and the movable door 9 can also be folded or closed when on duty outdoors, depending on the specific situation. At the same time, the side support mechanism 10 can fit the inclined ground to keep the stability of the expansion part, which is in line with the particularity of special vehicles.

[0026] See also Figure 1 , 2 4, wherein: two protective covers 11 are installed on the right side of the expansion box 4, and the electric push rod 1001 is located inside the protective cover 11.

[0027] In the present invention, the provision of the protective cover 11 can provide a certain degree of protection for the support mechanism 10 located outside the vehicle, thereby preventing the electric push rod 1001 from being eroded by external wind, rain and dust.

[0028] See also Figure 1 , wherein: evenly distributed installation grooves 12 are opened on the expansion box 4, and transparent glass 13 is installed on the inner wall of the installation groove 12.

[0029] In the utility model, when the special police vehicle stops working, if the expansion box body 4 is in a closed state, external observation can be carried out through the transparent glass 13 inside the installation groove 12, and the glass can be opened to realize ventilation.

[0030] See also Figures 1 to 3 , wherein: a plug 14 is fixedly connected to the right side of the rack 6 , and the plug 14 is arranged corresponding to the expansion slot 5 .

[0031] In the present invention, when the expansion box 4 completely enters the interior of the vehicle body 1, the plug 14 blocks and seals the expansion groove 5, thereby improving the sealing inside the special vehicle and facilitating thermal insulation.

[0032] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
