Claims

1. A landing gear for a vertical takeoff and landing aircraft, mounted on the bottom of the aircraft fuselage (10), characterized in that, include: The support mechanism (1) includes a support arm (11), a guide rod (12), and a support foot (13) connected in sequence. The support arm (11) is hinged to the fuselage (10), and the guide rod (12) is hinged to the support foot (13). The support arm (11) is slidably arranged along the guide rod (12). The guide rod (12) is fitted with a first elastic element (14) for recovering energy during the landing of the aircraft. The support arm (11) is provided with a locking mechanism (2). The locking mechanism (2) includes a locking element (21), a second elastic element (22), and a drive assembly. The second elastic element (22) is used to provide a preload force to lock the guide rod (12) with the locking element (21). The drive assembly is used to drive the locking element (21) to release the guide rod (12).

2. The landing gear for a vertical take-off and landing aircraft of claim 1, wherein, The support foot (13) is provided with a pressure sensor for detecting the magnitude of the pressure. The pressure sensor is connected to the control device, and the control device is connected to the drive assembly.

3. Tractor landing gear for a vertical take-off and landing aircraft according to claim 2, characterized in that, The guide rod (12) is provided with a plurality of helical teeth (121), which are arranged along the axial direction of the guide rod (12), and a tooth groove (122) is formed between any two adjacent helical teeth (121).

4. Tractor landing gear for a vertical take-off and landing aircraft according to claim 3, characterized in that, The toothed groove (122) includes a first groove surface (1221) extending along the diameter direction of the guide rod (12), and a second groove surface (1222) set at an acute angle to the first groove surface (1221). The first groove surface (1221) is used to prevent the locking member (21) from retracting when the first elastic member (14) releases potential energy.

5. Tractor landing gear for a vertical take-off and landing aircraft according to claim 4, characterized in that, The end of the locking member (21) is provided with a locking tooth (211) that cooperates with the tooth groove (122).

6. The landing gear for a vertical takeoff and landing aircraft according to any one of claims 1-5, characterized in that, The drive assembly includes an electric cylinder (23) and a connector (24). The electric cylinder (23) is used to drive the connector (24) to move along the axial direction of the guide rod (12). The connector (24) includes a connecting part, which is a wedge-shaped structure. The locking member (21) is provided with a wedge-shaped groove (212) that cooperates with the wedge-shaped structure. The wedge-shaped structure moves along the wedge-shaped groove (212) to drive the locking member (21) to move along the diameter direction of the guide rod (12).

7. Tricycle landing gear for a vertical take-off and landing aircraft according to claim 6, characterized in that, The connector (24) also includes a stepped portion connected to the electric cylinder (23), and the support arm (11) is provided with a guide groove that cooperates with the stepped portion.

8. The landing gear for a vertical take-off and landing aircraft of claim 1, wherein, One end of the first elastic element (14) is connected to the fixed seat (3) on the support arm (11), and the other end of the first elastic element (14) is connected to the base of the guide rod (12).

9. The landing gear for a vertical takeoff and landing aircraft of claim 1, wherein, Both the first elastic element (14) and the second elastic element (22) are springs.

10. An aircraft characterized by, Includes a fuselage (10), the bottom of which is fitted with landing gear for a vertical take-off and landing aircraft as described in any one of claims 1-9.
