The take-off and landing platform can fix the aircraft on the platform during turbulence, and can always maintain the adsorption force. When the aircraft is required to be released, multiple adsorption points can be released at the same time. The return accuracy of existing aircraft has tolerances. The landing troughs at three angles of the take-off and landing platform can guide the return deviation with a certain error. The existing mechanical fixed take-off and landing platform is very large in size, and it takes time to release the locking structure, and the simultaneity is extremely poor. The present invention has excellent simultaneity in releasing the aircraft. When taking off and releasing, the release time of multiple fixed positions is more synchronized; the aircraft can even be started first, and then released synchronously, which improves the mission efficiency.

[0031] like Figure 4 As shown, when the aircraft is landing, there is a heading deviation. When the aircraft is displaced horizontally, during the landing process, the take-off and landing slider 1b3 can slide in the groove of the guide positioning component 2b; when the aircraft 1 is landing, if the position deviation and heading deviation do not exceed the groove range of the guide positioning component 2b, the take-off and landing slider 1b3 can slide in the groove to the accurate position so that the landing gear adsorption module 1b1 is aligned with the platform adsorption module 2c;

[0032] The platform adsorption module 2c is an electromagnet for power-off demagnetization, and its shape is cylindrical; the outermost layer is a metal protective shell, the middle layer is an enameled wire winding coil, and the inner layer is a strong magnetic magnet; when the positive and negative poles of the platform adsorption module 2c are energized, a magnetic field that cancels out the inner magnet is formed to eliminate the magnetism of the inner strong magnet; the landing gear adsorption module 1b1 is an alloy material that is magnetically conductive and electrically conductive and not easily magnetized (such as silicon steel); the positive pole of the demagnetization control component 2d is connected to one landing gear adsorption module 1b1 (temporarily referred to as the positive pole landing gear adsorption module 1b1), and the negative pole is connected to another landing gear adsorption module 1b1 (temporarily referred to as the negative pole Landing gear adsorption module 1b1); the positive wires of all platform adsorption modules 2c on the take-off and landing platform 2 are connected to the conductive shell of the platform adsorption module 2c corresponding to the positive landing gear adsorption module 1b1; the negative wires of all platform adsorption modules 2c on the take-off and landing platform 2 are connected to the conductive shell of the platform adsorption module 2c corresponding to the negative landing gear adsorption module 1b1; through the above connection, after the aircraft 1 is started, the demagnetization control component 2d on the landing gear assembly 1b can perform power-on demagnetization control on all platform adsorption modules 2c through the contact point between the platform adsorption module 2c and the landing gear adsorption module 1b1;

[0033] The floating shock absorbing module 2d is a steel wire shock absorbing ball; the floating shock absorbing module 2d eliminates tiny displacements and deformations in 6 degrees of freedom; when the take-off and landing platform 2 is bumpy and vibrated, the floating shock absorbing module 2d absorbs and reduces the impact force at the connection between the platform adsorption module 2c and the landing gear adsorption module 1b1, and eliminates the effects of uneven contact points and uneven force caused by manufacturing tolerances, assembly tolerances, and force deformation of the landing gear assembly 1b.

[0040] Embodiment 2:

[0041] The present embodiment is different from the first embodiment in that the degaussing control component 2d is installed in the take-off and landing platform 2 to directly control the platform adsorption component; in this case, the degaussing control component 2d can be a radio remote control device or a simple power switch.

[0042] The aircraft 1 take-off and landing platform 2 is applied to a vehicle-mounted UAV or a ship-mounted take-off and landing platform;
