[0023] A specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0024] See also Figures 1 to 6 A multi-purpose carriage includes a frame 13 and a carriage 100 arranged on the frame 13, and wheels 14 are arranged on the frame 13. The multi-purpose carriage is preferably in the form of a mid-axle trailer, which can be separated from the front vehicle to avoid becoming a burden when the front vehicle is moving. The front vehicle is equipped with a power source and a central control room for operating a drone.

[0025] In addition to the frame 13 and the body 100, the multi-purpose body also includes an adjustment component, a control device and a battery, and the control device and the battery are fixed on the frame 13. The adjustment component is used to switch the body 100 between the folded state and the unfolded state under the control of the control device, and the battery is used to power the control device. When the body 100 is in the folded state, the shape is similar to the body 100 of the existing van or trailer; when the body 100 is in the unfolded state, a drone landing platform is formed, and the drone carried in the body 100 can take off directly from the drone landing platform after arriving at the work site and quickly put into operation.

[0026] See also Figures 1 to 6 The body 100 includes a bottom plate 1, a left side plate 2, a right side plate 3, a left front side plate 4, a right front side plate 5, a left rear side plate 6, a right rear side plate 7, a front air guide plate 8, a rear air guide plate 9, a left top plate 11 and a right top plate 12, see Figure 1 and 2When the box body 100 is in a folded state, the left front side panel 4 and the right front side panel 5 are assembled into a front side panel, the left rear side panel 6 and the right rear side panel 7 are assembled into a rear side panel, the left top panel 11 and the right top panel 12 are assembled into a top panel, the front side panel and the rear side panel are arranged oppositely, the left side panel 2 and the right side panel 3 are arranged oppositely, the top panel and the bottom panel 1 are arranged oppositely, the front air guide plate 8 is folded toward the front side panel, and the rear air guide plate 9 is folded toward the rear side panel. The bottom panel 1, the top panel, the left side panel 2, the right side panel 3, the front side panel and the rear side panel form a closed accommodation space, and the drone is placed in the accommodation space for transportation, and the box body 100 can protect the drone from wind and rain. In other embodiments, the box body 100 may not have a top panel, and the bottom panel 1, the left side panel 2, the right side panel 3, the front side panel and the rear side panel form an open accommodation space; or, the top panel may be integrated and located on one side of the left side panel 2 or the right side panel 3 when unfolded.

[0027] See also Figure 5 and 6 When the body 100 is in the unfolded state, the front air guide plate 8 fills the gap between the left front side panel 4 and the right front side panel 5, and the rear air guide plate 9 fills the gap between the left rear side panel 6 and the right rear side panel 7. The left top panel 11, the left side panel 2, the bottom panel 1, the right side panel 3, and the right top panel 12 are arranged in sequence from left to right, the front air guide plate 8, the bottom panel 1, and the rear air guide plate 9 are arranged in sequence from front to back, the left front side panel 4, the left side panel 2, and the left rear side panel 6 are arranged in sequence from front to back, the right front side panel 5, the right side panel 3, and the right rear side panel 7 are arranged in sequence from front to back, and the bottom panel 1, the left side panel 2, the right side panel 3, the left front side panel 4, the right front side panel 5, the left rear side panel 6, the right rear side panel 7, the front air guide plate 8, the rear air guide plate 9, the left top panel 11 and the right top panel 12 are assembled into a UAV take-off and landing platform without a gap.

[0028] The present invention discloses a design in which the box 100 is unfolded to become a take-off and landing platform for a drone, so that the transportation tool of the drone can also serve as a take-off and landing platform for the drone, which increases the use. The drone can take off and be put into operation after arriving at the work site without unloading and handling, which is conducive to disaster relief. Since the presence of the gap may cause changes in the wind field when the drone takes off and lands on a platform with a gap, affecting the flight safety and stability of the drone, the present invention discloses a design of a front wind deflector and a rear wind deflector to avoid the presence of a gap in the platform formed by the unfolding of the box 100. In order to achieve the rapid unfolding of the box 100, the adjustment component is an automated device controlled by a control device, which is faster and more labor-saving than manually unfolding the box 100.

[0029] In order to realize the unfolding of the carriage 100, the control device is used to execute a method for unfolding the carriage 100, so that the carriage 100 changes from a folded state to an unfolded state, and the method for unfolding the carriage 100 includes the following steps: S1: By adjusting the components, the angle between the front air deflector 8 and the rear air deflector 9 and the bottom plate 1 is expanded from 90° to 180°; S2: By adjusting the components, the angle between the left side plate 2 and the right side plate 3 and the bottom plate 1 is expanded from 90° to 180°; S3: By adjusting the components, the included angle between the left front side panel 4 and the left rear side panel 6 and the left side panel 2 is expanded from 90° to 180°; S4: Enlarging the angle between the right front side panel 5 and the right rear side panel 7 and the right side panel 3 from 90° to 180° by adjusting the components; S5: Enlarging the angle between the left top plate 11 and the left side plate 2 from 90° to 180° by adjusting the assembly; S6: The angle between the right top plate 12 and the right side plate 3 is expanded from 90° to 180° by adjusting the assembly.

[0030] In order to unfold the car body 100 more quickly, after step S1, steps S2 to S6 are performed in parallel. In other embodiments, steps S2 to S6 may also be performed in sequence or in other ways.

[0031] By first executing steps S2 to S6 and then executing step S1, the compartment body 100 can be restored from the unfolded state to the folded state.

[0032] In order to improve the sealing performance between the left top plate 11 and the right top plate 12 when the body 100 is in the folded state, a mounting convex strip 121 is provided on the right top plate 12 to better protect the right top plate 12, and a top plate sealing strip 10 is installed on the mounting convex strip 121. In other embodiments, there may be no sealing strip between the left top plate 11 and the right top plate 12, no sealing, or sealing may be achieved by other means.

[0033] See also Figure 7 and 8 The top plate sealing strip 10 includes an elastic strip portion 10b and a clamping strip portion 10a. The clamping strip portion 10a is clamped on the mounting convex strip 121. When the compartment 100 is in the unfolded state, the state of the top plate sealing strip 10 is shown in FIG. Figure 5 When the compartment 100 is in the folded state, see Figure 7 The top plate sealing strip 10 is located between the left top plate 11 and the right top plate 12 , and the elastic strip portion 10 b is squeezed and deformed by the left top plate 11 and the right top plate 12 , thereby achieving sealing between the left top plate 11 and the right top plate 12 . Figures 1 to 6 The sealing structure between the plates is not shown. The sealing between the left front side plate 4 and the right front side plate 5 and the sealing between the left rear side plate 6 and the right rear side plate 7 can also refer to the sealing method between the left top plate 11 and the right top plate 12.

[0034] The left side panel 2, the right side panel 3 and the front air guide plate 8 are respectively hinged to the bottom panel 1, the left top panel 11, the left front side panel 4 and the left rear side panel 6 are respectively hinged to the left side panel 2, and the right top panel 12, the right front side panel 5 and the right rear side panel 7 are respectively hinged to the right side panel 3. The adjustment assembly includes a plurality of adjustment units 17, and the adjustment unit 17 includes an electric push rod and two connection seats respectively hinged to the two ends of the electric push rod, and the number and specifications of the adjustment units 17 connected to different panels may be different.

[0035] like Figure 3 and 4 A visual safety window 31 is also provided on the right side panel 3 to facilitate the user to observe the drone fixed in the compartment 100 , and there is no gap between the visual safety window 31 and the side panel.

[0036] See also Figure 2 and 9 The left side panel 2 and the right side panel 3 are respectively connected to the bottom panel 1 through two adjusting units 17, the front air guide plate 8 is connected to the bottom panel 1 through one adjusting unit 17, the left top panel 11 is connected to the left side panel 2 through two adjusting units 17, the left front side panel 4 and the left rear side panel 6 are respectively connected to the left side panel 2 through one adjusting unit 17, the right top panel 12 is connected to the right side panel 3 through two adjusting units 17, and the right front side panel 5 and the right rear side panel 7 are respectively connected to the right side panel 3 through one adjusting unit 17.

[0037] The two connecting seats of the adjustment unit 17 are respectively fixed on the two plates connected to the adjustment unit 17. The control device controls the extension and retraction of the electric push rod to make the two plates connected to the adjustment unit 17 rotate relative to each other. During the relative rotation of the two plates, the electric push rod and the connecting seat rotate relative to each other. The electric push rod has a simple structure and is easy to install. In other embodiments, the adjustment unit can also be a power mechanism of other forms.

[0038] The frame 13 is located on the lower side of the body 100. When the body 100 is in the unfolded state, the adjustment unit 17 connecting the bottom plate 1 and the left side plate 2, the right side plate 3 and the front wind deflector 8 is located on the lower side of the UAV take-off and landing platform to prevent these adjustment units 17 from interfering with the take-off and landing of the UAV; since these adjustment units 17 are always located outside the body 100, in order to protect these adjustment units 17, these adjustment units 17 are covered with protective covers 18, and the specifications of the protective covers 18 of adjustment units 17 of different specifications are different.

[0039] When the body 100 is in a folded state, the adjustment unit connecting the left side panel 2 with the left top panel 11, the left front side panel 4 and the left rear side panel 6 and the adjustment unit 17 connecting the right side panel 3 with the right top panel 12, the right front side panel 5 and the right rear side panel 7 are located inside the body 100 and are protected by the body 100.

[0040] like Fig. 9Since the adjustment units 17 connecting the left side plate 2 and the bottom plate 1 and the right side plate 3 and the bottom plate 1 need to withstand a large tensile force, in order to prevent the connection seats of these adjustment units 17 from breaking with the bottom plate 1, these adjustment units 17 in the carriage are reinforced adjustment units. The connection seat included in the reinforced adjustment unit for connecting with the bottom plate 1 is a T-shaped connecting frame 19. The T-shaped connecting frame 19 has a bottom plate connection 191, a frame connection end 192 and an electric push rod connection end 193. The bottom plate connection end 191 and the frame connection end 192 are respectively fixed on the bottom plate 1 and the frame 13 to disperse the tensile force. The electric push rod connection end 193 is used to be hinged with the electric push rod 17 included in the reinforced adjustment unit.

[0041] The rear air deflector 9 is a tailgate of the vehicle body 100 for loading and unloading goods. In addition to the multiple adjustment units 17, the adjustment assembly also includes a cantilever tailgate drive mechanism for lifting and rotating the tailgate. Many existing vans have tailgates and cantilever tailgate drive mechanisms. The tailgate of existing vans mainly functions to load and unload goods. Using the tailgate as the rear air deflector 9 can simplify the structure of the vehicle body 100.

[0042] The multi-purpose carriage further comprises a plurality of leveling legs 15. The frame 13 is provided with wheels 14. The bottom plate 1 and the leveling legs 15 are respectively arranged above and below the frame 13. The leveling legs 15 are adjustable in length and are hinged to the frame 13. Figure 1 and 2 During driving, the leveling legs 15 are substantially parallel to the bottom plate 1 and the length is shortened to the shortest; see Figure 3 and 4 When the car body 100 is in the unfolded state, the leveling legs 15 rotate to a position substantially perpendicular to the bottom plate 1. By adjusting the angle and length of the leveling legs 15, the UAV landing platform can be adjusted to a posture perpendicular to the direction of gravity, thereby solving the problem that the UAV landing platform is not level when the multi-purpose car body is parked on a slope or a bumpy ground.

[0043] Since the UAV landing platform has a large area and heavy weight, in order to ensure the horizontality of the UAV landing platform and prevent the platform from bending due to gravity to become a high middle and low surrounding shape, the multi-purpose carriage also includes a plurality of auxiliary support rods 16, the auxiliary support rods 16 are adjustable in length and are hinged to the left side plate 2 or the right side plate 3, see Figure 1 and 2 During driving, the auxiliary support rod 16 is substantially parallel to the left side plate 2 / right side plate 3; see Figure 5 and 6 When the body 100 is in the unfolded state, the auxiliary support rod 16 rotates to a position substantially perpendicular to the left side plate 2 / right side plate 3. By adjusting the angle and length of the auxiliary support rod 16, the four sides of the UAV landing platform can be supported to keep the UAV landing platform flat.

[0044] The multi-purpose carriage further includes a clearance lamp 20 and a landing indicator lamp, which are arranged on the carriage body 100. Figure 1 and 2 When the box 100 is in the folded state, the clearance lights 20 are located outside the box 100 and are arranged around the box 100. The landing indicator light is located inside the box 100. The landing indicator light is used to assist the drone to land when the box 100 is in the unfolded state. Figure 3 and 4 The specific position and structure of the landing indicator light are not shown in the figure. Those skilled in the art can arrange the landing indicator light and other indicator devices according to the indicator light setting requirements of the UAV take-off and landing platform.

[0045] The multi-purpose box 100 also includes a drone charging interface, which is electrically connected to the battery and is used to charge the drone. The specific position and structure of the charging device are not shown in the drawings, and those skilled in the art can set the charging interface above the bottom plate 1. A drone fixing device is also provided in the box 100, which is used to fix the drone.

[0046] The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention. It should be noted that any modification, equivalent replacement, improvement, etc. made by a person skilled in the art within the spirit and principle of the present invention after reading this specification should be included in the protection scope of the present invention.
