Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 8As shown, the present invention provides a vehicle-mounted unmanned aerial vehicle storage and deployment platform, including a roof platform 1; a sliding cover 2, slidably installed on one side of the top of the roof platform 1; an electric lifting platform 3, movably installed on one side of the inner cavity of the roof platform 1; a unmanned aerial vehicle placement component 4, movably installed on the inner side of the electric lifting platform 3; a correction component 5, including a rubber water storage bag 501, the rubber water storage bag 501 is fixedly installed on the inner side of the unmanned aerial vehicle placement component 4, the rubber water storage bags 501 are fixedly connected to each other through valve flaps 502, and the interior of the unmanned aerial vehicle placement component 4 is provided with a correction iron ball 503 located on the inner side of the rubber water storage bag 501, and the correction iron ball 503 is movably installed on the top of the inner cavity of the unmanned aerial vehicle placement component 4 through a second spherical connector 504.

[0037] Due to the deformability of the rubber water storage bag 501 itself, when the entire drone placement component 4 tilts, the correction iron ball 503 is always vertically downward due to gravity, thereby pushing and smoothly squeezing one side of the rubber water storage bag 501 to deform, so that the water inside is switched through the valve flap 502 to replenish the inside of the other rubber water storage bag 501.

[0038] like Figure 2 As shown, the drone placement assembly 4 includes a movable platform 401, a drone placement platform 402 and a first spherical connector 403;

[0039] The movable platform 401 is movably installed inside the electric lifting platform 3 , and the drone placement platform 402 is movably connected to the top of the movable platform 401 through a first spherical connector 403 .

[0040] By adopting the above solution, through the design of the first spherical connector 403, a spherical connection can be achieved between the movable platform 401 and the drone placement platform 402, so that the drone placement platform 402 can rotate at a free angle on the top of the movable platform 401.

[0041] like Figure 2 and Figure 7 As shown, a limiting telescopic rod 7 located outside the rubber water storage bag 501 is fixedly installed on the top of the movable platform 401, and the top of the limiting telescopic rod 7 is spherically connected to the outer inner cavity of the drone placement platform 402.

[0042] By adopting the above solution: by setting a limited telescopic rod 7, when the drone placement platform 402 as a whole tilts relative to the movable platform 401, the corresponding limited telescopic rod 7 will be squeezed and stretched, so that the overall tilt of the drone placement platform 402 can be limited and supported.

[0043] like Figure 2 and Figure 7As shown, the inner cavity of the roof platform 1 is provided with a first hydraulic assembly 8 located at the bottom of the electric lifting platform 3, and the first hydraulic assembly 8 includes a first hydraulic cylinder 801, a first hydraulic piston rod 802, a connecting plate 803 and a first oil pipe 804;

[0044] The first hydraulic cylinder 801 is fixedly installed inside the roof platform 1 and is located below the outer side of the electric lifting platform 3. The first hydraulic piston rod 802 is movably installed in the inner cavity of the first hydraulic cylinder 801. The connecting plate 803 is hinged between the inner side of the first hydraulic piston rod 802 and the bottom of the electric lifting platform 3. The first oil pipe 804 is fixedly connected to the bottom of the first hydraulic cylinder 801.

[0045] By adopting the above solution: by providing a connecting plate 803, when the electric lifting platform 3 as a whole moves up and down, the connecting plate 803 can be driven to deflect, thereby driving the first hydraulic piston rod 802 as a whole to move toward or away from each other.

[0046] like Figure 2 and Figure 7 As shown, the inner side of the electric lifting platform 3 is provided with a second hydraulic assembly 9 located outside the movable platform 401, and the second hydraulic assembly 9 includes a second hydraulic cylinder 901, a second hydraulic piston rod 902 and a second oil pipe 903;

[0047] The second hydraulic cylinder 901 is fixedly installed on the outer end of the top of the electric lifting platform 3, the second hydraulic piston rod 902 is movably installed in the inner cavity of the second hydraulic cylinder 901, the bottom end of the second hydraulic piston rod 902 is fixedly connected to the outer side of the top of the movable platform 401, and the second oil pipe 903 is fixedly connected to the outer side of the bottom of the second hydraulic cylinder 901.

[0048] The above solution is adopted: by providing a second hydraulic cylinder 901, when hydraulic oil is introduced into or discharged from the inner cavity at the bottom of the second hydraulic cylinder 901, the second hydraulic cylinder 901 as a whole is hydraulically driven to drive the entire drone placement component 4 to perform upward and downward telescopic movement.

[0049] like Figure 2 As shown, the top of the first oil pipe 804 is movably connected to the bottom of the second oil pipe 903 .

[0050] By adopting the above scheme: by providing a first oil pipe 804 and a second oil pipe 903, when the first hydraulic piston rod 802 as a whole moves toward or away from each other, the inner cavity of the first hydraulic cylinder 801 can introduce or extract hydraulic oil into or from the inner cavity of the second hydraulic cylinder 901 through the first oil pipe 804 and the second oil pipe 903.

[0051] like Figure 3 and Figure 7As shown, a clamping assembly 10 located outside the rubber water storage bag 501 is provided on the top of the drone placement platform 402, and the clamping assembly 10 includes a movable frame 101, a clamping block 102 and a power spring 103;

[0052] The movable frame 101 is movably installed on the top of the drone placement platform 402 , and the clamping block 102 is movably installed inside the movable frame 101 . The outer side of the clamping block 102 is elastically connected to the inner wall of the movable frame 101 through a power spring 103 .

[0053] The above solution is adopted: by providing a power spring 103, when the movable frame 101 is extended upward as a whole, the elastic force of the power spring 103 can be released, thereby pushing the clamping blocks 102 to move toward each other to clamp the bottom of the drone, so that the drone is fixed on the top of the drone placement platform 402.

[0054] like Figure 3 As shown, a lifting mechanism 11 located below the movable frame 101 is provided at the bottom of the drone placement platform 402, and the lifting mechanism 11 includes a sliding column 1101, a return spring 1102 and a second pneumatic component 1103;

[0055] The sliding column 1101 is fixedly installed in the middle of the outer side of the bottom surface of the movable frame 101. The sliding column 1101 is elastically connected to the bottom of the drone placement platform 402 through the return spring 1102. The second pneumatic component 1103 is arranged between the outer side of the sliding column 1101 and the inside of the drone placement platform 402.

[0056] The above scheme is adopted: by providing a reset spring 1102, when the second pneumatic component 1103 pushes the sliding column 1101 and the movable frame 101 to move downward as a whole, the second pneumatic component 1103 as a whole will be stretched synchronously, and when the elastic force of the second pneumatic component 1103 is released, the sliding column 1101 and the movable frame 101 will be pulled upward and reset as a whole.

[0057] like Figure 3 As shown, the second pneumatic assembly 1103 includes a second pneumatic groove 11031 and a second pneumatic piston rod 11032;

[0058] The second pneumatic groove 11031 is opened inside the UAV placement platform 402 and is located outside the sliding column 1101. The bottom of the second pneumatic groove 11031 is fixedly connected to the top surface of the bottom end of the sliding column 1101, and the second pneumatic piston rod 11032 is movably installed in the inner cavity of the second pneumatic groove 11031.

[0059] By adopting the above solution, a second pneumatic piston rod 11032 is provided. When gas enters the top of the inner cavity of the second pneumatic groove 11031, the gas pressure pushes the second pneumatic piston rod 11032 to drive the sliding column 1101 and the movable frame 101 to move downward as a whole.

[0060] like Figure 4 As shown, the electric lifting platform 3 is provided with a first pneumatic assembly 6 located inside the bottom of the second hydraulic piston rod 902, and the first pneumatic assembly 6 includes a first pneumatic groove 601, a first pneumatic piston rod 602 and a vent pipe 603;

[0061] The first pneumatic groove 601 is opened inside the electric lifting platform 3 and is located at the inner bottom of the second hydraulic piston rod 902. The first pneumatic piston rod 602 is movably installed in the inner cavity of the first pneumatic groove 601. The first pneumatic groove 601 is fixedly connected with the second pneumatic groove 11031 through the ventilation pipe 603, and the ventilation pipe 603 is made of rubber.

[0062] The above scheme is adopted: by providing a ventilation pipe 603, when the movable platform 401 as a whole moves upward, it will push the first pneumatic piston rod 602 to retract into the inner cavity of the first pneumatic groove 601, and then the gas at the top of the inner cavity of the first pneumatic groove 601 enters into the inner cavity of the second pneumatic groove 11031 through the ventilation pipe 603. At this time, since the ventilation pipe 603 is made of rubber, it is deformable, so that when the movable platform 401 and the drone placement platform 402 move up and down as a whole, the ventilation pipe 603 can continue to maintain the connection effect between the first pneumatic groove 601 and the second pneumatic groove 11031.

[0063] The working principle and use process of the present invention:

[0064] First, when the operator needs to release the drone for use, he can first control the sliding cover 2 to move to one side and open it, and then control the electric lifting platform 3 to drive the drone placement component 4 as a whole upward. At this time, the connecting plate 803 will be deflected to push the first hydraulic piston rod 802 to move towards each other, so as to push the hydraulic oil in the inner cavity of the first hydraulic cylinder 801 through the first oil pipe 804 and the second oil pipe 903 to be introduced into the inner cavity of the second hydraulic cylinder 901, so that the hydraulic pressure in the bottom cavity of the second hydraulic cylinder 901 becomes larger, and then the second hydraulic piston rod 902 can be pushed to drive the movable platform 401 and the drone placement platform 402 to extend upward as a whole.

[0065] Then, when the vehicle body tilts as a whole, the correction iron ball 503 can remain vertically downward due to the action of gravity, and the entire drone placement platform 402 is tilted relative to the correction iron ball 503. Therefore, at this time, the surface of the correction iron ball 503 will squeeze and push one side of the rubber water storage bag 501 inside the drone placement platform 402, so that the water inside the corresponding rubber water storage bag 501 is squeezed and pushed through the correction iron ball 503 into the other rubber water storage bag 501. Since the squeezed rubber water storage bag 501 has less water and becomes lighter, and the water is added to the other rubber water storage bag 501, which deforms and expands and becomes heavier, the entire drone placement platform 402 will deflect in the direction of becoming heavier until the entire drone placement platform 402 is in a horizontal state, and then the drone on the top is in a horizontal state.

[0066] Finally, when the movable platform 401 is driven upward to the highest point, the top of the movable platform 401 will squeeze the first pneumatic piston rod 602 to extend completely upward into the first pneumatic groove 601, and then the gas in the inner cavity at the top of the first pneumatic groove 601 can be introduced into the second pneumatic groove 11031 through the ventilation pipe 603, so that the second pneumatic piston rod 11032 can push the sliding column 1101 to drive the movable frame 101 to move downward as a whole, and then the movable frame 101 moves downward as a whole, so that the bottom inclined surface of the clamping block 102 is squeezed by the top surface of the drone placement platform 402, and shrinks towards each other inside the movable frame 101, and finally the clamping block 102 can be completely stored in the movable frame 101, and the movable frame 101 is completely stored in the drone placement platform 402, and the clamping block 102 on the drone is smoothly released, and then the drone can be controlled to fly out for operation.
